In the packaging of an absorbent article, a main body peeling sheet and a packaging sheet are arranged on the non-skin-facing side of the absorbent article. When peeling the main body adhesive portion from the main body peeling sheet during unfolding of the packaging of the absorbent article, the front end of the packaging sheet such as a tag tape is held and the packaging sheet is pulled in the unfolding direction relative to the absorbent article. However, the main body adhesive portion of the absorbent article is in contact with the main body peeling sheet, not the packaging sheet. Therefore, there have been cases where it has been difficult to peel the flap peeling sheet from the flap adhesive portion.

Therefore, there is a demand for a packaging body for an absorbent article in which the absorbent article is individually packaged by a packaging sheet, and in which the main body peeling sheet can be easily peeled from the main body adhesive portion when the packaging body is unfolded.

(1) Overview of the embodiment

From the description in this specification and the attached drawings, at least the following are clear:

According to one embodiment, a packaging body of an absorbent article is provided in which absorbent articles are individually packaged by a packaging sheet. The absorbent article comprises: a main body portion; a flap portion extending outwardly in the width direction from the main body portion; a main body adhesive portion arranged on a non-skin-facing side of the main body portion and having an adhesive for fixing the main body portion to underwear; a flap adhesive portion arranged on a non-skin-facing side of the flap portion and having an adhesive for fixing the flap portion to underwear; a main body release sheet covering the main body adhesive portion and further joined via the packaging sheet and the main body fixing portion; and a flap release sheet covering the flap adhesive portion in a state in which the flap portion is folded toward the skin-facing side of the main body portion. The packaging body is folded inwardly from a first folding line extending in the width direction from a first end edge, which is an outer edge in the front-back direction of the packaging body, and further, in a folded state from the first folding line, is folded inwardly from a second folding line extending in the width direction and located on a second end edge side opposite to the first end edge. At least a part of the flap adhesive portion and the flap release sheet are arranged closer to the second end edge side than the second fold line. In a third folded state folded from the second fold line, the packaging sheet and the flap release sheet are faced in a region where the flap fixing portion joins the packaging sheet and the flap release sheet. In the third folded state, the main body fixing portion and the flap fixing portion overlap in the thickness direction.

In a conventional absorbent article packaging body, a main body peeling sheet and a packaging sheet are arranged on the non-skin-facing side of the absorbent article. When peeling the main body adhesive portion from the main body peeling sheet during unfolding of the absorbent article packaging body, the front end of the packaging sheet, such as a tag tape, is held and the packaging sheet is pulled in the unfolding direction with respect to the absorbent article. However, the main body adhesive portion of the absorbent article is in contact with the main body peeling sheet, not the packaging sheet. Therefore, when unfolding the packaging body, even if the packaging sheet is pulled in the unfolding direction with respect to the absorbent article, the force in the unfolding direction is not appropriately applied to the main body peeling sheet, and there are cases where it is difficult to peel the main body peeling sheet from the main body adhesive portion, or it is difficult to peel the flap peeling sheet from the flap adhesive portion. Therefore, the packaging body according to the present embodiment is configured so that, when unfolding the packaging body, the main body peeling sheet can be easily peeled from the main body adhesive portion, and the flap peeling sheet can be easily peeled from the flap adhesive portion.

According to this aspect, when unfolding the packaging body from the third folded state to the second folded state, since the main body fixing portion and the flap fixing portion overlap in the thickness direction, force is transmitted from the packaging sheet to the main body peeling sheet and the absorbent article through the main body fixing portion, so that the packaging body is unfolded from the second fold line as a starting point, and the flap peeling sheet can be pulled in the direction away from the flap adhesive portion through the flap fixing portion. Accordingly, the main body peeling sheet can be easily peeled from the main body adhesive portion, and the flap peeling sheet can be easily peeled from the flap adhesive portion.

According to a preferred embodiment, the main body fixing portion and the flap fixing portion may be arranged closer to the first fold line than the center of the front-back direction of the second fold line and the first fold line when the packaging body is folded based on the first fold line and the second fold line.

According to this aspect, when unfolding the packaging body with the second fold line as the starting point, since the main body fixing portion and the flap fixing portion are separated from the second fold line, which serves as the rotation axis, by pulling the packaging sheet, the first fold line side can easily move in the rotational direction with the second fold line side as the center.

According to a preferred embodiment, the flap portions are provided as a pair on both sides of the width direction of the main body portion, the flap adhesive portions are respectively provided on the pair of flap portions, the flap portions are spaced apart from each other in a state where they are folded toward the skin-facing side of the main body portion, the flap peeling sheet covers the pair of flap adhesive portions, and the flap fixing portion may overlap an area between the pair of flap adhesive portions in the thickness direction.

When unfolding the packaging body from the second folding line as a starting point, when the user pulls the packaging sheet, the flap peeling sheet moves away from the flap adhesive portion. At this time, since the flap adhesive portion and the flap fixing portion do not overlap, the area in the flap peeling sheet that is in contact with the flap fixing portion moves first, and the area in the flap peeling sheet that is in contact with the flap adhesive portion follows and moves. The tip of each flap portion stands up from the base of each flap as a starting point, and the pair of flap portions and the main body portion surround an approximately triangular space.

In a state where the flap portion and the absorbent article are arranged to form a triangle, the center of the width direction of the flap release sheet (the portion overlapping the flap fixing portion) is pulled toward the packaging sheet, so that the flap release sheet is bent. At this time, the flap release sheet tries to maintain a flat state by being pulled simultaneously with the packaging sheet. As a result, the outer edge of the flap adhesive portion in the state where the flap portion is folded to the main body portion begins to peel from the flap release sheet. The flap release sheet gradually separates from the flap adhesive portion, so that the flap release sheet can be easily peeled from the flap adhesive portion.

According to a preferred embodiment, the widthwise length of the flap fixing portion may be longer than the widthwise length of the main body fixing portion.

According to this aspect, when unfolding the packaging body from the second folding line, the flap peeling sheet can be pulled in the peeling direction over a wide range in the width direction through the flap fixing portion. Therefore, the flap peeling sheet can be easily peeled from the flap adhesive portion.

According to a preferred embodiment, the widthwise length of the flap fixing portion may be shorter than the widthwise length of the main body fixing portion.

According to this aspect, when the leading edge of each flap is deformed to stand up with respect to the origin of each flap, the leading edge of each flap can be further pulled toward the center in the width direction of the main body portion, thereby increasing the standing angle of the flap. Accordingly, the flap peeling sheet can be peeled more easily from the flap adhesive portion.

According to a preferred embodiment, the flap fixing member may be arranged spaced apart from the flap adhesive members in the width direction in the region between the pair of flap adhesive members.

According to this aspect, the standing angle of the flap can be further increased, so that the flap peeling sheet can be easily peeled from the flap adhesive portion.

According to a preferred embodiment, the flap adhesive portion has a first flap adhesive portion and a second flap adhesive portion which is positioned on the inner side of the first flap adhesive portion in the width direction when the absorbent article is in a deployed state, and an edge of the first flap adhesive portion on the second short edge side may be positioned on the second short edge side of the second flap adhesive portion.

According to this aspect, the edge on the second end side of the flap adhesive portion becomes the side away from the second fold line, which is the starting point of unfolding, when unfolding the package from the second fold line. The second flap adhesive portion located on the base side of the flap portion extends further away from the starting point of unfolding than the first flap adhesive portion located on the tip side of the flap portion. Therefore, when the tip of each flap is deformed to stand up with respect to the base of each flap, the tip side of the flap portion is likely to stand up earlier than the base side of the flap portion. By increasing the standing angle of the flap portion, the outer edge of the flap adhesive portion and the flap release sheet are gradually separated, so that the flap release sheet can be more easily separated from the flap adhesive portion.

According to a preferred embodiment, the main body fixing part may have a first main body fixing part arranged in a first region on the first short edge side rather than the first fold line.

According to this aspect, since the packaging sheet and the main body peeling sheet are joined at the first main body fixing portion in the first region on the first edge side rather than the first fold line, when the packaging sheet is pulled so as to be unfolded from the second fold line, it becomes easier to unfold the absorbent article via the packaging sheet and the main body peeling sheet.

According to a preferred embodiment, the body fixing part may have the first body fixing part and a second body fixing part arranged in a second region between the first folding line and the second folding line in the unfolded state of the packaging body.

According to this aspect, the packaging sheet and the main body peeling sheet are joined by the main body fixing portion in both the first region and the second region. When force is applied to the first fold line side through the packaging sheet so as to unfold from the second fold line, force can be applied to both sides of the first fold line, making it easier to unfold the absorbent article through the packaging sheet and the main body peeling sheet.

According to a preferred embodiment, the first body fixing portion and the second body fixing portion may overlap in the thickness direction in the third folded state.

According to this aspect, when force is applied to both sides of the first folding line by the first main body fixing portion and the second main body fixing portion, the force becomes easy to transmit, making it easier to unfold the absorbent article through the packaging sheet and the main body peeling sheet.

A packaging body of an absorbent article according to another aspect is a packaging body of an absorbent article in which the absorbent article is individually packaged by a packaging sheet. The absorbent article has a main body portion having an absorbent core, a pair of flap portions extending on opposite outer sides in the width direction from the main body portion, a main body adhesive portion having an adhesive that is arranged on a non-skin-facing side of the main body portion and fixes the main body portion to underwear, a pair of flap adhesive portions that are arranged on a non-skin-facing side of each of the flap portions and have an adhesive that is arranged on a non-skin-facing side of the main body portion and fixes the main body portion to underwear, and a flap release sheet that covers the pair of flap adhesive portions when the flap portions are folded on the skin-facing side of the main body portion. The above packaging body, in a first folded state in which the flap portion is folded toward the skin-facing side of the main body portion, a first end edge, which is an outer edge of the front-back direction of the packaging body, is folded inwardly from a first fold line extending in the width direction as a starting point, and in a second folded state folded from the first fold line as a starting point, is folded inwardly from a second fold line extending in the width direction and located on a second end edge side opposite to the first end edge. At least a portion of the flap adhesive portion and the flap release sheet are arranged closer to the second end edge side than the second fold line. In a third folded state folded from the second fold line as a starting point, the packaging body has a flap fixing portion that joins the packaging sheet and the flap release sheet in a region where the packaging sheet and the flap release sheet face each other. The absorbent core has a low unit weight portion in which the unit weight of the absorbent core is lower than that of the surroundings. The above low unit weight portion has a second side low unit weight region extending in the front-back direction on the second edge side from the second folding line.

In the conventional absorbent article packaging, the packaging sheet is pulled in the unfolding direction through the front end of the packaging sheet such as a tag tape, and the absorbent article is unfolded while the flap peeling sheet is pulled together with the packaging sheet. However, since the flap peeling sheet is in contact with the flap adhesive portion, the flap portion is easily deformed to follow the flap peeling sheet through the flap adhesive portion. When the flap portion follows the flap peeling sheet, the tip of the flap portion stands up with respect to the root of the flap portion. In this state, when the flap peeling sheet is pulled together with the packaging sheet, when the flap peeling sheet slides in the width direction with respect to the flap portion, shear stress is generated by the flap adhesive portion. Therefore, there were cases where it was difficult to peel the flap peeling sheet from the flap adhesive portion. Therefore, the packaging according to the present embodiment is configured so that the flap peeling sheet can be easily peeled from the flap adhesive portion.

According to the present embodiment, when the packaging body is unfolded from the second fold line as a starting point, when force is applied to the first fold line through the packaging sheet, the packaging body rotates in a region on the side of the first fold line relative to the second fold line, with respect to the region on the side of the second short edge relative to the second fold line, and the flap release sheet moves in the direction of rotation together with the packaging sheet according to the movement. At this time, the region on the side of the second short edge relative to the second fold line is easily bent in the width direction due to the deformation starting point extending in the front-back direction by the second-side low-unit-weight region. Therefore, when the flap portion is pulled via the flap release sheet and the flap adhesive portion, the base portion of the flap portion moves inward in the width direction. The flap release sheet is pulled in the unfolding direction together with the packaging sheet, and tries to maintain a flat state. On the other hand, the angle at which the flap portion stands up from the skin-facing side of the absorbent article increases as the base portion of the flap portion moves inward in the width direction. Because of this, the flap release sheet and the flap portion become easy to separate in the unfolding direction, so that the outer edge of the flap adhesive portion peels off from the flap release sheet, allowing the flap release sheet to be easily peeled off from the flap adhesive portion.

According to a preferred embodiment, the low unit weight portion has a front-rear low unit weight region parallel to the front-rear direction, and the front-rear low unit weight region does not have to be provided in a region on the first edge side rather than the first fold line in the unfolded state.

According to this aspect, when unfolding from the second fold line as a starting point, the region on the second short edge side rather than the second fold line is moved in the rotational direction relative to the region on the first fold line side rather than the second fold line. At this time, the region between the first fold line and the flap fixing portion is difficult to deform inward in the width direction, and relatively, the region on the second short edge side rather than the second fold line is easy to deform inward in the width direction. Therefore, when the flap portion is pulled via the flap peeling sheet and the flap adhesive portion, the base portion of the flap portion moves inward in the width direction, so that the standing angle of the flap portion tends to increase.

According to a preferred embodiment, the front-rear low-unit weight region may not be provided in a region between the first folding line and the second folding line in the unfolded state.

According to this aspect, when unfolding from the second fold line as a starting point, the region on the first end edge side is less likely to be deformed than the second fold line, and the region on the second end edge side is relatively more likely to be deformed inward in the width direction than the second fold line. Therefore, when the flap portion is pulled through the flap peeling sheet and the flap adhesive portion, the base portion of the flap portion moves inward in the width direction, and the standing angle of the flap portion tends to increase.

According to a preferred embodiment, the second side low-unit weight region and the flap fixing portion may be arranged closer to the first fold line than the center of the front-back direction of the second fold line and the first fold line in the third folded state.

According to this aspect, since the flap fixing portion is separated from the second fold line, which becomes the rotation axis when unfolding from the second fold line, it becomes easy to move the flap peeling sheet in the unfolding direction by pulling the packaging sheet during unfolding. At this time, since the deformation starting point due to the second-side low-unit-weight region is provided on the first fold line side, the standing angle of the flap portion on the first fold line side can be further increased.

According to a preferred embodiment, the low-unit-weight portion has a first-side low-unit-weight region arranged closer to the first edge than the first fold line in the deployed state, and the first-side low-unit-weight region may extend outward in the width direction toward the first fold line in the region between the first fold line and the flap fixing portion in the deployed state.

According to the present embodiment, a deformation origin point is formed in a region between the first fold line and the flap fixing portion, which extends outward in the width direction toward the first fold line side. When viewed in the cross-section in the thickness direction, an absorbent core on the flap peeling sheet side relative to the flap fixing portion forms a deformation origin point extending outward in the width direction from the flap fixing portion toward the first fold line due to a deformation origin point by the first-side low-unit-weight region. Therefore, when the flap peeling sheet is pulled by the packaging sheet, a deformation origin point is also formed in the flap peeling sheet that extends outward in the width direction from the flap fixing portion toward the first fold line. The flap peeling sheet is deformed so as to separate from the flap adhesive portion, so that the flap peeling sheet can be easily peeled from the flap adhesive portion.

According to a preferred embodiment, the present invention has a body peeling sheet that covers a body adhesive portion and is bonded to the packaging sheet via a body fixing portion, wherein the body fixing portion is arranged in a region on the first edge side rather than the first fold line in an unfolded state, and the low unit weight portion may have an intermediate low unit weight region located in a region between the first fold line and the second fold line in an unfolded state.

According to this aspect, the force applied to the packaging sheet is transmitted to the body peeling sheet through the body fixing portion. The body peeling sheet is in contact with the body adhesive portion of the absorbent article, and thus easily transmits force to the absorbent article. Therefore, in the third folded state, when the user applies force to the first fold line through the packaging sheet, the force is transmitted to the body peeling sheet through the body fixing portion, and the first fold line side of the body portion easily moves in the rotational direction centered on the second fold line. When the first fold line side of the body portion moves in the rotational direction centered on the second fold line in the third folded state, the absorbent core in the area between the first fold line and the second fold line is deformed based on the intermediate low unit weight area. By deforming the absorbent core in the area between the first fold line and the second fold line, the flap peeling sheet is deformed to separate from the flap adhesive portion, and the flap peeling sheet can be easily peeled from the flap adhesive portion.

According to a preferred embodiment, the second side low unit weight region may extend in the width direction in a region on the second end side relative to the flap fixing portion in the deployed state.

According to this aspect, since the second-side low-unit-weight region extends in the width direction in the region on the second end side relative to the flap fixing portion, distortion can be absorbed by the second-side low-unit-weight region. Even when the packaging sheet cannot be pulled substantially perpendicularly to the second end of the absorbent article, the second-side low-unit-weight region absorbs distortion, so that the flap peeling sheet can be pulled substantially perpendicularly to the flap adhesive portion. Therefore, the flap peeling sheet can be easily peeled from the flap adhesive portion.

According to a preferred embodiment, the second side low-unit weight region may extend in the width direction in the region between the flap fixing portion and the first folding line in the deployed state.

According to this aspect, the region between the flap fixing portion and the first fold line is more likely to be subjected to force in the unfolding direction in the fourth unfolding process. Since the second side low unit weight region is provided in the region between the flap fixing portion and the first fold line in the unfolded state, it is easier to obtain the effect of absorbing distortion of the main body portion.

According to a preferred embodiment, the second side low unit weight region may reach the outer edge of the absorbent core.

According to this aspect, the region on the second end side of the absorbent article and the region overlapping the flap fixing portion can be divided by the second side low unit weight region, so that the effect of absorbing distortion of the main body portion can be more easily obtained.

In addition, a packaging body of an absorbent article according to another aspect is a packaging body of an absorbent article in which the absorbent article is individually packaged by a packaging sheet. The absorbent article comprises a main body portion, a pair of flap portions extending outwardly in the width direction from the main body portion, a pair of flap adhesive portions each arranged on a non-skin-facing side of the flap portions and having an adhesive for fixing the flap portions to underwear, and a flap release sheet covering the flap adhesive portions when the flap portions are folded toward the skin-facing side of the main body portion. The packaging body, in a first folded state in which the flap portion is folded toward the skin-facing side of the main body portion, has a first end edge, which is an outer edge of the packaging body in the front-back direction, folded inwardly with a first fold line extending in the width direction as a starting point, and in a second folded state folded with the first fold line as a starting point, has a second fold line extending in the width direction and located on the second end edge side opposite to the first end edge, folded inwardly with the second fold line as a starting point. At least a part of the flap adhesive portion and the flap release sheet are arranged closer to the second end edge side of the absorbent article than the second fold line. In a third folded state folded with the second fold line as a starting point, the packaging body has a flap fixing portion that joins the packaging sheet and the flap release sheet in a region where the packaging sheet and the flap release sheet face each other. The above-described main body portion has an absorbent core, a surface sheet positioned on the skin-facing side of the absorbent core, and a standing-up leak-prevention gather positioned on the skin-facing side of the surface sheet. The leak-prevention gather has a contraction portion that stands up by contraction of a leak-prevention elastic member, and a starting point portion that serves as a starting point for standing up of the contraction portion. The starting point portion has a first starting point portion positioned further outside in the width direction than the contraction portion. The contraction portion has an extension portion that extends inwardly in the width direction from the first starting point portion, and a fold-back portion that is folded outwardly in the width direction from an inner edge of the extension portion as a starting point. The fold-back portion has the leak-prevention elastic member, and is configured to be able to stand up with respect to the extension portion in a flap region that extends in the width direction from the flap portion. The outer edge of the fold-back portion is arranged further outside in the width direction than the absorbent core.

When unfolding a conventional absorbent article packaging, the front end of the packaging, such as a tag tape, is held, the packaging sheet is pulled in the unfolding direction, and the flap peeling sheet is pulled together with the packaging sheet while unfolding the absorbent article. However, since the flap peeling sheet is in contact with the flap adhesive portion, the flap portion is easily deformed to follow the flap peeling sheet via the flap adhesive portion. When the flap portion follows the flap peeling sheet, the flap portion is twisted, and the flap adhesive portion is unintentionally adhered, so that there are cases where the flap adhesive portion cannot be used appropriately when the absorbent article is used. Therefore, the packaging according to the present embodiment is configured to suppress the problem of unintentional adhesion in the packaging of an absorbent article in which the flap peeling sheet is pulled together with the packaging sheet and the flap peeling sheet is peeled from the flap adhesive portion. More specifically, it is configured so that the main body peeling sheet can be easily peeled from the main body adhesive portion, thereby suppressing the problem of the flap adhesive portion unintentionally sticking.

According to this aspect, since the outer edge which becomes the standing vertex of the folded portion is located further outside in the width direction than the absorbent core, when the flap portion tries to move inward in the width direction during unfolding in the third folded state, the standing vertex of the folded portion is likely to touch the inner surface of the flap portion in the folded state of the flap portion. The outer side in the width direction can also be pressed toward the wearer by the standing vertex of the folded portion. Therefore, even if the flap portion is pulled together with the flap peeling sheet, the movement of the flap portion inward in the width direction can be controlled. By suppressing the twisting of the flap portion, it is possible to suppress the problem of the flap adhesive portions sticking to each other or the flap adhesive portions sticking to an unintended area.

According to a preferred embodiment, the inner edge of the first starting point may be arranged on the outer side in the width direction of the absorbent core in the flap region.

According to this aspect, since the inner edge of the first starting point portion, which is the standing point of the entire shrinkage portion, is located further outside in the width direction than the absorbent core, when the flap portion attempts to move inward in the width direction, the shrinkage portion is likely to come into contact with the inner surface of the flap portion in the first folded state, and the flap portion can be pressed toward the outside in the width direction.

According to a preferred embodiment, the starting point may have a second starting point positioned further outside the contraction portion in the forward/reverse direction, and an inner edge of the second starting point may be arranged in an area overlapping the absorbent core.

According to this aspect, since the second starting point is overlapped with a relatively rigid absorption core, the contraction section becomes more easily erected.

According to a preferred embodiment, the flap adhesive portion may be spaced apart in the width direction from a flap folding line that folds the flap portion toward the skin-facing side of the main body portion.

The vicinity of the flap fold line is prone to wrinkles or twists due to folding of the flap portion. According to this aspect, it is possible to suppress unintentional adhesion of the flap adhesive portion due to wrinkles or the like due to folding of the flap portion.

According to a preferred embodiment, the flap fixing portion overlaps an area between the pair of flap adhesive portions in the thickness direction, and may be spaced apart from the flap adhesive portions.

According to this aspect, in the third folded state, when the user pulls the packaging sheet, the flap peeling sheet moves in the unfolding direction away from the flap adhesive portion in the thickness direction. At this time, since the flap adhesive portion is spaced apart from the flap fixing portion in the width direction, it is difficult to move in the unfolding direction together with the flap fixing portion, and it is easy to maintain a flat state. Therefore, it is possible to suppress the problem that the flap peeling sheet is easy to peel from the flap adhesive portion, and the flap adhesive portions stick to each other or the flap adhesive portions stick to an unintended area.

According to a preferred embodiment, the starting point has a second starting point located further outside the contraction portion in the front-back direction, and in a region overlapping the second starting point of the leak-prevention gather, a leak-prevention joint that joins the fold-back portion and the extension portion, and a leak-prevention non-joined portion located further outside the fold-back portion in the width direction and in which the fold-back portion and the extension portion overlap without being joined, are provided, and the leak-prevention non-joined portion may reach the outer edge of the fold-back portion.

According to this aspect, the outer edge of the fold-backed portion is not joined to the extension portion, but stands up with respect to the extension portion. The fold-backed portion also becomes more likely to stand up on the outer side in the width direction toward the wearer, thereby pressing the flap portion toward the outer side in the width direction, thereby restricting the movement of the flap portion inward in the width direction.

According to a preferred embodiment, the outer edge of the anti-seal joint may be arranged on the outer side in the width direction relative to the outer edge of the absorbent core.

The standing point of the fold-backed portion of the overlapping region in the thickness direction with the second starting point becomes the outer edge of the anti-swelling joint. Since the standing point of the fold-backed portion is located on the outer side in the width direction than the absorbent core, when the flap portion tries to move inward in the width direction, the shrinkage portion is likely to come into contact with the inner surface of the flap portion in the width direction, so that the flap portion can be pressed toward the outer side in the width direction.

According to a preferred embodiment, the spring-preventing elastic member may be arranged on the outer side in the width direction relative to the flap peeling sheet in the first folded state.

The outer region in the width direction from the flap release sheet is not covered by the flap release sheet, has low rigidity, and is prone to deformation. By providing a spring-preventing elastic member of the fold-back portion in that region, it is possible to suppress the flap portion's widthwise inward movement in the region with relatively low rigidity.

According to a preferred embodiment, in the unfolded state of the packaging body, the area of the flap adhesive portion in a region inside the center of the width direction of the flap portion may be larger than the area of the flap adhesive portion in a region outside the center of the width direction of the flap portion.

The area inside the center in the width direction of the flap portion is close to the flap fold line, and wrinkles or twists are likely to occur due to folding of the flap portion. By increasing the area of the flap adhesive portion in the area inside the center in the width direction of the flap portion, wrinkles or twists in the vicinity of the flap fold line can be suppressed, and wrinkles or the like can be suppressed from occurring in the flap adhesive portion.

According to a preferred embodiment, the absorbent core may be provided with a low unit weight portion having a lower unit weight of absorbent material than the surroundings in the flap region.

According to this aspect, the absorbent core of the flap region is easily bent based on the low-unit weight portion. Therefore, when the flap release sheet is pulled away from the flap adhesive portion, the flap release sheet moves in the unfolding direction while the base portion of the flap portion moves inward in the width direction. At this time, the flap portion is pressed outward in the width direction by the contraction portion, making it easy to maintain the flap adhesive portion in a flat state. It is possible to suppress the formation of wrinkles or the like in the flap adhesive portion.

According to a preferred embodiment, the low-unit weight portion may overlap in the region between the pair of flap adhesive portions in the thickness direction.

The absorbent core of the flap region is easily bent based on the low-unit weight portion between a pair of flap adhesive portions. Therefore, when the flap adhesive portion is pulled through the flap release sheet, the flap portion is more easily erected. At this time, the flap portion is pressed outward in the width direction by the contraction portion, making it easy to maintain the flap adhesive portion in a flat state. Therefore, while suppressing the formation of wrinkles, etc. in the flap adhesive portion, the flap release sheet can be moved in the unfolding direction, and the flap release sheet can be peeled from the flap adhesive portion.

According to a preferred embodiment, the absorbent article has a body adhesive portion having an adhesive that is arranged on the non-skin-facing side of the body portion and fixes the body portion to underwear, and the low-unit-weight portion may be provided in an area that does not overlap the body adhesive portion and the flap adhesive portion when the package is in an unfolded state.

According to this aspect, the area that does not overlap the main body adhesive portion and the flap adhesive portion is an area that is not bonded to the underwear when worn, and is thus prone to deformation. By providing the low-unit-weight portion in that area, the absorbent core is more prone to deformation with the low-unit-weight portion as a starting point, and the flap portion is more prone to standing up. The flap release sheet and the flap portion are easily separated in the unfolding direction, and the flap release sheet can be peeled from the flap adhesive portion while suppressing twisting of the flap portion.

In addition, there are cases where the drawings include parts whose dimensional relationships or ratios are different from each other.

Fig. 1 is a plan view of the package in the unfolded state as viewed from the skin-facing side. Fig. 2 is a plan view of the package in the unfolded state as viewed from the non-skin-facing side. The plan views shown in Figs. 1 and 2 are plan views of the unfolded state. The unfolded state is a state in which the absorbent article and the packaging sheet are not folded, and the absorbent article is unfolded to the extent that wrinkles due to leak-prevention gathers or the like are not formed. Here, the "skin-facing side" corresponds to the side facing the wearer's skin during use. The "non-skin-facing side" corresponds to the side facing away from the wearer's skin during use.

The packaging body (110) of the absorbent article (hereinafter referred to as the packaging body) has an absorbent article (1) and a packaging sheet (100) for individually packaging the absorbent article. The packaging body (110) has a first end edge and a second end edge, which are outer edges in the front-back direction of the packaging body (110). The first end edge is an end edge located on the inside of the packaging body in an individually packaged packaging state as shown in Fig. 11 and the like, and the second end edge is an end edge located on the outside of the packaging body in the packaging state. The inside of the packaging body means the inner side in the thickness direction of the packaging body (110) in the packaging state. The first end edge of the present embodiment is a rear end edge (110R), and the second end edge is a front end edge (110F). In addition, in another form, the first end edge may be a trailing edge (110R), and the second end edge may be a front edge (110F). In addition, the front edge (110F) of the packaging body (110) may be formed by the front edge (100F) of the packaging sheet (100), or may be formed by the front edge (1F) of the absorbent article (1). Similarly, the rear edge (110R) of the packaging body (110) may be formed by the rear edge (100R) of the packaging sheet (100), or may be formed by the rear edge (1R) of the absorbent article (1). The front edge (110F) of the packaging body (110) of the present embodiment is formed by the front edge (100F) of the packaging sheet (100), and the rear edge (110R) of the packaging body (110) is formed by the rear edge (1R) of the absorbent article (1).

The absorbent article (1) has a front-back direction (L) and a width direction (W). The front-back direction (L) is a direction extending from the front side (back side) of the wearer to the back side (dorsal side), or a direction extending from the back side of the wearer to the front side. The width direction (W) is a direction orthogonal to the front-back direction (L). The absorbent article has a thickness direction (T) extending to the skin-facing side (T1) and the skin-non-facing side (T2).

An absorbent article (1) has a central region (S3), a front region (S1), and a rear region (S2). The central region (S3) is a region having an excretory port contact portion that contacts the wearer's excretory port (e.g., vaginal port). When the absorbent article is worn on underwear, the central region (S3) is located at the crotch of the underwear. That is, the central region is a region that is placed at the wearer's crotch, that is, between the wearer's legs. The central region (S3) may be positioned toward the front in the absorbent article. More specifically, the center of the central region (S3) in the front-back direction (L) may be located toward the front of the center of the absorbent article (1) in the front-back direction (L).

The front region (S1) is located in front of the central region (S3). The front edge of the front region (S1) defines the front edge of the absorbent article (1). The rear region (S2) is located in back of the central region (S3). The rear edge of the rear region (S2) defines the rear edge of the absorbent article (1). The length in the front-back direction (L) of the rear region (S2) may be longer than the length in the front-back direction (L) of the central region (S3).

An absorbent article (1) has a main body portion (2) and a flap portion (5). The main body portion (2) has at least an absorbent core (31), a surface sheet (10), and a back sheet (20), and has a vertically elongated shape. The flap portion (5) extends outward in the width direction from the main body portion (2). The flap portion (5) may extend outward in the width direction (W) from the outer edge of the absorbent core (31) in the central region (S3). In addition, in the present embodiment, the outer edge is an outer short edge in the width direction, and the inner edge is an inner short edge in the width direction. The flap portion (5) may be composed of a wing (3) and a hip flap (4). In the present embodiment, the wing (3) may be provided in the central region (S3), and the hip flap (4) may be provided in the rear region (S2). The flap portion (5) of the present invention is positioned in front of the second fold line (FL2) described later, and is configured to be deployable when the package (110) is deployed from the second fold line (FL2). The flap portion (5) of the present embodiment is configured by a wing (3). In another form, in a form in which the hip flap (4) is positioned in front of the second fold line (FL2), the hip flap (4) may constitute the flap portion of the present invention.

The wings (3) are provided as a pair on both sides in the width direction of the main body (2), and the hip flaps (4) are also provided as a pair on both sides in the width direction of the main body (2). The wing (3) and the hip flap (4) may be configured by laminating a side sheet (15) and a back sheet (20) described later. The wing (3) is configured to be folded back toward the back sheet (20). When in use, the wing (3) is folded toward the non-skin-facing side of the crotch portion of the underwear.

The hip flap (4) is positioned rearward of the wing (3) and is provided in the rear region (S2). The hip flap (4) is not folded when in use and is placed between the underwear and the buttocks of the wearer. In the present embodiment, the hip flap (4) is not provided with an absorbent material. Instead, the hip flap (4) may be provided with an absorbent material.

The leading edge of the wing (3) is defined by the joint of the wing (3) and corresponds to the forward portion among the two portions that are most inwardly offset in the width direction (W). The leading edge of the wing (3) may define the boundary between the central region (S3) and the forward region (S1). The trailing edge of the wing (3) is defined by the joint of the wing (3) and corresponds to the rearward portion among the two portions that are most inwardly offset in the width direction (W). The trailing edge of the wing (3) may be located between the central region (S3) and the rear region (S2). Here, the region between the leading edge of the wing (3) and the trailing edge of the wing (3) in the front-back direction (L) is referred to as a “flap region.” Since the flap region of the present embodiment coincides with the central region, it is hereinafter described as the central region (S3).

The absorbent article (1) is configured to be individually packaged by a packaging sheet (100). The packaging body (110) is folded to the skin-facing side (T1) of the main body portion (2) with the flap fold line (FL5) as a starting point in the unfolded state in which the absorbent article (1) is placed on the packaging sheet (100). Fig. 3 is a plan view of the packaging body (110) as viewed from the skin-facing side in the first folded state in which the flap part (5) is folded to the skin-facing side of the main body portion. Fig. 4 is a plan view of the packaging body (110) as viewed from the non-skin-facing side in the first folded state. The boundary between the main body portion (2) and the flap part (5) may be the flap fold line (FL5) or the joint (the base of the wing) of the flap part (5). The flap fold line (FL5) extends in the forward-backward direction (L) and may be parallel to the forward-backward direction (L).

The packaging body (110) is folded inwardly of the packaging body (110) with the first folding state in which the wing (3) is folded on the skin-facing side (T1) of the main body (2), with the first folding line (FL1) extending in the width direction (W) as a starting point. The packaging body (110) is folded inwardly of the packaging body with the second folding line (FL2) as a starting point, in the second folding state in which the wing (3) is folded along the first folding line (FL1). The second folding line (FL2) is located closer to the shear edge (110F), which is the second short edge, than the first folding line (FL1).

In addition, the packaging body (110) of the present embodiment is folded inwardly of the packaging body with the third folding line (FL3) extending in the width direction (W) as a starting point in the third folded state folded by the second folding line (FL2). The third folding line (FL3) is located closer to the shear edge (110F), which is the second short edge, than the second folding line (FL2). In the fourth folded state folded by the third folding line (FL3), the shear edge (100F) of the packaging sheet (100) is fixed to the outer surface of the packaging sheet (100) by the tag tape (102). In this way, a packaging state is achieved in which the absorbent article (1) is individually packaged by the packaging sheet (100) (see Fig. 11). In addition, the inner surface (100T) of the packaging sheet (100) is a surface positioned on the absorbent article (1) side in the unfolded state, and the outer surface (100B) of the packaging sheet (100) is a surface positioned on the opposite side to the absorbent article (1) in the unfolded state. As shown in Fig. 1, the absorbent article (1) of the present embodiment has, in the unfolded state, a first region (R11) between the first fold line (FL1) and the rear edge (1R) of the absorbent article (1), a second region (R12) between the first fold line (FL1) and the second fold line (FL2), a third region between the second fold line (FL2) and the third fold line (FL3), and a fourth region (R14) between the third fold line (FL3) and the front edge (1F) of the absorbent article (1). Additionally, in other forms, the packaging body (110) may not be folded based on the third folding line (FL3).

FIG. 5 is a cross-sectional view taken along line 1A-1A in FIG. 1. An absorbent article (1) includes a surface sheet (10) facing the wearer's skin, a back sheet (20) facing the opposite side to the wearer's skin, and an absorbent core (31) disposed between the surface sheet (10) and the back sheet (20). The surface sheet (10) faces the wearer's skin during use. The back sheet (20) faces the opposite side to the wearer's skin during use. The absorbent core (31) includes an absorbent material that absorbs body fluid and extends along the front-back direction (L) of the absorbent article.

The surface sheet (10) is composed of any sheet-shaped material having a liquid-permeable structure, such as a nonwoven fabric, a woven fabric, a porous plastic sheet, a mesh sheet, etc. As the material for the woven fabric or nonwoven fabric, either natural fiber or chemical fiber can be used.

The back sheet (20) is a liquid-impermeable sheet. The back sheet (20) can be a sheet in which a breathable resin film is bonded to a nonwoven fabric such as a polyethylene sheet, a polypropylene sheet, a breathable resin film, a spun bond, or a spun lace.

Fig. 6 is a plan view of an absorbent core. The absorbent core (31) is arranged at least in the central region (S3) and the rear region (S2). In addition, the absorbent core may extend from the central region (S3) to the front region (S1). The absorbent core (31) may be composed of an absorbent material that absorbs liquid. The absorbent core (31) may be surrounded by a core wrap (not shown). The core wrap may cover the absorbent core (31) at least on the skin-facing side more than the absorbent core (31). As a specific example, the core wrap may have a sheet arranged on the skin-facing side more than the absorbent core (31) and a sheet arranged on the non-skin-facing side more than the absorbent core (31).

The absorbent material constituting the absorbent core (31) may be formed of, for example, hydrophilic fibers, pulp, and superabsorbent polymer (SAP). The core wrap may be composed of, for example, a nonwoven fabric or a tissue sheet. The sheet on the skin-facing side and the sheet on the non-skin-facing side constituting the core wrap may be composed of the same sheet. As a variation, the absorbent core (31) may not be covered by the core wrap. In this case, the absorbent core (31) may be covered by the surface sheet (10) and the back sheet (20).

The absorbent core (31) may have multiple regions having different unit weights. Fig. 6 is a plan view of the skin-facing side (T1) of the absorbent core (31). The absorbent core (31) may have at least a high unit weight portion (33), a low unit weight portion (34), and a medium unit weight portion (35). The unit weight of the absorbent material (pulp) of the high unit weight portion (33) is higher than the unit weight of the absorbent material of the medium unit weight portion (35), and the unit weight of the absorbent material (pulp) of the medium unit weight portion (35) is higher than the unit weight of the absorbent material (pulp) of the low unit weight portion (34). The high unit weight portion (33) is thicker than the surrounding absorbent cores (31) and forms a medium-to-high unit weight portion (36). The high unit weight portion (33) has a first high unit weight portion (331) and a second high unit weight portion (332) arranged with a gap in the front-back direction. The second high unit weight portion (332) is located at the rear side of the first high unit weight portion (331). A first low unit weight portion (341) may be arranged between the first high unit weight portion (331) and the second high unit weight portion (332) in the front-back direction (L).

The high-unit weight portion (33) may be arranged at the center of the absorbent core (31) in the width direction (W). The outer edge of the high-unit weight portion (33) may be located further inside the outer edge (31E) of the absorbent core (31) in the width direction (W). At least a part of the high-unit weight portions [the first high-unit weight portion (331) and the second high-unit weight portion (332)] (33) may be arranged in the central region (S3). The high-unit weight portion (33) may extend in the front-back direction (L) beyond the central region (S3). The center of the high-unit weight portion (33) in the front-back direction (L) may be located forward of the center of the absorbent article (1) in the front-back direction (L), or may be located forward of the center of the central region (S3) in the front-back direction. In addition, the center of the front-back direction (L) of the high-unit weight portion (33) becomes the center of the front-back direction of the front edge of the first high-unit weight portion (331) and the rear edge of the second high-unit weight portion (332).

As shown in Fig. 5, a plurality of through holes (38) may be formed in the high-unit-weight portion (33) that penetrate from the skin-facing surface of the absorbent article (1) to the non-skin-facing surface of the absorbent core (31) in the thickness direction (T). The through holes (38) may be formed in a plurality at intervals when viewed from a planar surface. Since the through holes (38) are formed in the high-unit-weight portion (33), even when a large amount of body fluid such as menstrual blood or urine is excreted at one time, it is difficult for the body fluid to be drawn into the absorbent core (31) and overflow. It is possible to maintain the dryness of the skin-facing surface of the absorbent article, and effectively maintain a good fit and a comfortable feeling.

The through hole (38) may be provided on the rear side of the high-unit weight portion (33), or may be provided on the second low-unit weight portion (342) of the rear area (S2). It is easy to draw body fluid flowing along the skin in the direction of gravity in a sleeping position more toward the absorbent side.

Between the outer edge (33E) of the high-unit weight portion (33) and the outer edge (31E) of the absorbent core (31) and between the shear edge of the high-unit weight portion (33) and the shear edge of the absorbent core (31), a medium-unit weight portion (35) having a lower unit weight than the high-unit weight portion (33) and a higher unit weight than the low-unit weight portion (34) is arranged. The medium-unit weight portion (35) is an area, among areas having different unit weights, that is arranged at the outer edge and the shear edge of the absorbent core (31). In addition, in a configuration where an area having different unit weights is provided at the outer edge (31E) of the absorbent core (31), this area is the area having the highest proportion at the outer edge (31E), and in a configuration where an area having different unit weights is provided at the front edge of the absorbent core (31), this area is the area having the highest proportion at the shear edge. The unit weight of the intermediate weight portion (35) of the present embodiment is 300 g/㎡, and is a portion other than the low unit weight portion (34) and the high unit weight portion (33), and is arranged over the entire area in the front-back direction (L) of the outer edge (31E) of the absorbent core (31) and the entire area in the width direction of the shear edge of the absorbent core (31).

The low unit weight portion (34) may at least have a first low unit weight portion (341), a pair of second low unit weight portions (342) positioned rearward of the first low unit weight portion (341), a pair of third low unit weight portions (343) positioned rearward of the second low unit weight portion, and front and rear low unit weight portions (345). The low unit weight portion (34) has a lower unit weight and lower rigidity than the intermediate weight portion (35). Therefore, when force is applied to the absorbent core (31), the low unit weight portion is most likely to deform. Therefore, the low unit weight portion (34) deforms to absorb the force, or the low unit weight portion (34) becomes a starting point of deformation of the absorbent core (31).

The unit weight of the low unit weight portion (34) is preferably 150 g/m2 or less, and the unit weight of the low unit weight portion of the present embodiment is 100 g/m2. The low unit weight portion (34) may be less than 50%, more preferably less than 35%, of the unit weight of the absorbent core (31) adjacent to the low unit weight portion (34). By increasing the difference in unit weight between the low unit weight portion (34) and its surroundings, when force is applied to the absorbent core (31), the force can be locally concentrated on the low unit weight portion (34). As a result, as described later, the low unit weight portion is deformed, and the absorbent core (31) can be made to fit the body better.

The low unit weight portion (34), the medium unit weight portion (35), and the high unit weight portion (33) may be defined as follows. The area having the highest proportion on the outer edge (31E) of the absorbent core (31) is defined as the medium unit weight portion (35). When viewed in cross section, a portion that is 20% or thicker than the thickness of the medium unit weight portion (35) and extends in the plane direction is defined as the high unit weight portion (33). The boundary between the high unit weight portion (33) and the medium unit weight portion (35) is defined by defining the center in the thickness direction (T) of a portion extending in the plane direction of the medium unit weight portion (35) and a portion extending in the plane direction of the high unit weight portion (33), and a portion that is thicker than the center in the thickness direction (T) is defined as the high unit weight portion (33), and a portion that is thinner than the center in the thickness direction (T) is defined as the medium unit weight portion (35). Likewise, when viewed in cross section, a portion that is thinner by 20% or more than the thickness of the intermediate weight portion (35) and extends in the plane direction is designated as the low unit weight portion (34). The boundary between the low unit weight portion (34) and the intermediate weight portion (35) is defined by the center in the thickness direction of the portion extending in the plane direction of the intermediate weight portion (35) and the portion extending in the plane direction of the low unit weight portion (34), and a portion that is thicker than the center in the thickness direction (T) is designated as the intermediate weight portion (35), and a portion that is thinner than the center in the thickness direction (T) is designated as the low unit weight portion (34).

The second low unit weight portion (342) is spaced apart from the first low unit weight portion (341) in the front-back direction (L) and is provided at the rear side relative to the first low unit weight portion (341). The second low unit weight portion (342) may be positioned at the rear side relative to the central region (S3) or may be positioned at the rear side relative to the rear edge of the wing (3). The second low unit weight portion (342) may extend inwardly in the width direction (W) from the outer edge (31E) of the absorbent core (31) and may also extend obliquely relative to the width direction (W).

The third low-unit weight portion (343) is spaced apart from the second low-unit weight portion (342) in the front-rear direction (L) and is provided on the rear side relative to the second low-unit weight portion (342). The third low-unit weight portion (343) may be arranged in the rear region (S2). The second low-unit weight portion (342) may extend inwardly in the width direction (W) from the outer edge (31E) of the absorbent core (31) and may also extend obliquely with respect to the width direction (W).

The front and rear low unit weight portions (345) are provided in the rear region (S2). The front and rear low unit weight portions (345) may span the center of the width direction (W) of the absorbent core (31). The front and rear low unit weight portions (345) are provided along the front and rear direction at the center of the width direction (W) of the absorbent core (31). The front and rear low unit weight portions (345) are provided further rearward than the second high unit weight portion (332) and further rearward than the central region (S3). The front and rear low unit weight portions (345) may extend rearward from the rear edge of the second high unit weight portion (332).

The low unit weight portion (34) has a plurality of low unit weight regions. The low unit weight portion (34) has a second-side low unit weight region (R41) that extends in the front-back direction on the front edge side relative to the second fold line (FL2). The second-side low unit weight region (R41) may be arranged in at least one of the third region (R13) and the fourth region (R14), and is composed of the first low unit weight portion (341), a part of the second low unit weight portion (342), and a part of the front-back low unit weight portions (345). The second low unit weight portion (342) straddles the second fold line (FL2), and the region overlapping the second fold line (FL2) and the region on the rear edge side relative to the second fold line (FL2) do not constitute the second-side low unit weight region (R41). Likewise, the front and rear low unit weight portion (345) straddles the second fold line (FL2), and the region overlapping the second fold line (FL2) and the region on the rear edge side of the second fold line (FL2) do not constitute the second-side low unit weight region (R41). In Fig. 6, the second-side low unit weight region (R41) of the second low unit weight portion (342) and the second-side low unit weight region (R41) by the front and rear low unit weight portions (345) are indicated by drawing a diagonal line. In addition, the second-side low unit weight region (R41) should extend in the front-back direction (L) even a little, and should not be parallel to the width direction (W). Therefore, the entire first low unit weight portion (341) constitutes the second-side low unit weight region (R41).

At least a part of the second-side low-unit-weight region (R41) overlaps the flap fixing portion (92) in the third folded state. In the present embodiment, the second-side low-unit-weight region (R41) of the first low-unit-weight portion (341) overlaps the flap fixing portion (92) in the third folded state. As shown in Fig. 12, the second-side low-unit-weight region (R41) is arranged closer to the first fold line (FL1) than the center (CL12) in the front-back direction of the second fold line (FL2) and the first fold line (FL1) in the third folded state. The second-side low-unit-weight region (R41) extends in the width direction (W) in the region closer to the front edge than the flap fixing portion (92) in the unfolded state. Specifically, a part of the first low-unit-weight portion (341) is arranged in a region between the flap fixing portion (92) and the first fold line (FL1) in the packaged state, closer to the front edge than the flap fixing portion (92). In addition, the second-side low-unit-weight portion (R41) may extend in the width direction even a little, and may not be parallel to the front-back direction. The second-side low-unit-weight portion (R41) may reach the outer edge of the absorbent core (31). Specifically, the first low-unit-weight portion (341) reaches the outer edge of the absorbent core (31).

The low unit weight portion (34) has a front-rear low unit weight region (R42) that is parallel to the front-rear direction (L). The front-rear low unit weight region (R42) is composed of the front-rear low unit weight portion (345). The front-rear low unit weight region (R42) is arranged across the second folding line (FL2). The front-rear low unit weight region (R42) is arranged in the second region (R12) and the third region (R13), and is not arranged in the first region (region on the first edge side relative to the first folding line) (R11) and the fourth region (R14).

The low unit weight portion (34) has a first side low unit weight region (R43) arranged at the rear edge side relative to the first fold line (FL1) in the deployed state. The first side low unit weight region (R43) may be located in the first region (R11) and is formed by a part of the third low unit weight portion (343). In Fig. 6, the first side low unit weight region (R43) in the third low unit weight portion (343) is indicated by a diagonal line. The first side low unit weight region (R43) extends outward in the width direction (W) toward the first fold line (FL1) in the region between the first fold line (FL1) and the flap fixing portion (92) in the deployed state shown in Fig. 6. In addition, in the present embodiment, the positions of the flap fixing part (92) and the main body fixing part (91) in the unfolded state are positions corresponding to the positions of the flap fixing part (92) and the main body fixing part (91) in the packed state when unfolded. The positions of the flap fixing part (92) and the main body fixing part (91) when unfolded are shown in FIG. 1 and FIG. 2.

The low unit weight portion (34) has an intermediate low unit weight portion (R44) arranged in an area between the first folding line (FL1) and the second folding line (FL2) in the unfolded state. The intermediate low unit weight portion (R44) may be located in the second area (R12), and is composed of a part of the third low unit weight portion (343), a part of the second low unit weight portion (342), and a part of the front and rear low unit weight portions (345). In Fig. 6, the intermediate low unit weight portion (R44) is indicated by drawing a diagonal line.

Continuing, based on Fig. 1, the pressing portion will be described. The first pressing portion (81) overlaps at least a portion of the first low unit weight portion (341) and extends along the first low unit weight portion (341). The manner in which the first pressing portion (81) extends along the first low unit weight portion (341) includes not only a configuration in which the direction in which the first low unit weight portion (341) extends and the direction in which the first pressing portion (81) extends coincide, but also a configuration in which the angle formed by the two directions is less than 5 degrees. In addition, the direction in which the first low unit weight portion (341) extends and the direction in which the first pressing portion (81) extends become lines connecting the width centers of the portions in a configuration in which each portion has a constant width. The first pressing portion (81) may be provided so as to overlap at least a portion of the first low unit weight portion (341) and extend along the first low unit weight portion (341). The outer edge of the first compression portion (81) may be positioned inside the outer edge (31E) of the absorbent core (31), and the inner edge of the first compression portion (81) may terminate within the first low-unit-weight portion (341). The first compression portion (81) may be positioned inside the outer edge (33E) (see Fig. 6) of the high-unit-weight portion (33) in the width direction (W). In a configuration having a plurality of high-unit-weight portions, the outer edge of the high-unit-weight portion that is positioned furthest outside in the width direction is used.

In addition, the second compression portion (82) overlaps at least a portion of the second low-unit-weight portion (342) and extends along the second low-unit-weight portion (342). The outer edge of the second compression portion (82) may be positioned further inward than the outer edge of the absorbent core (31), and the inner edge of the second compression portion (82) may be positioned further inward in the width direction (W) than the inner edge of the second low-unit-weight portion (342). The third compression portion (83) overlaps at least a portion of the third low-unit-weight portion (343) and extends along the third low-unit-weight portion (343). The outer edge (83E) of the third compression member (83) may be positioned further inward than the outer edge (31E) of the absorbent core (31), and the inner edge of the third compression member (83) may be positioned further inward in the width direction (W) than the inner edge of the third low-unit weight member (343).

The first compression member (81), the second compression member (82), and the third compression member (83) are provided as a pair at intervals in the width direction (W). The first compression member (81), the second compression member (82), and the third compression member (83) are line-symmetrical with respect to a center line that passes through the center of the width direction (W) of the absorbent article and also extends in the front-back direction (L).

The absorbent article (1) may have a second sheet (not shown) arranged between the surface sheet (10) and the absorbent core (31). The second sheet may be a liquid-permeable sheet that allows liquid such as body fluid to pass through. Preferably, the hydrophilicity of the second sheet is higher than that of the surface sheet (10). The second sheet may be composed of the same material as the surface sheet (10).

The absorbent article (1) may have a side sheet (15) covering the outer edge of the surface sheet (10). The side sheet (15) covers the outer edge of the surface sheet (10) in the width direction (W) and extends outward in the width direction (W) from the surface sheet (10). Furthermore, in the present embodiment, the absorbent article (1) has the side sheet (15), but the absorbent article (1) may not have the side sheet (15). In this case, the surface sheet (10) may cover the entire absorbent core. Furthermore, in the present invention, the outer edge is an outer end in the width direction, and the inner edge is an inner end in the width direction.

The side sheet (15) can be composed of the same material as the surface sheet (10). However, in order to prevent body fluid attached to the surface sheet (10) from leaking outward of the absorbent article (1) in the width direction (W) by running over the side sheet (15), it is preferable that the side sheet (15) has hydrophobic or water-repellent properties. The side sheet (15) may be arranged on the outer edge of the absorbent core, the wing (3), and the hip flap (4) in the width direction (W).

The absorbent article (1) may have a standing-up leak-prevention gather (60). The leak-prevention gather (60) is positioned on the skin-facing side (T1) of the surface sheet (10) and is configured to be able to stand up on the skin-facing side (T1) more than the surface sheet (10) when worn. Fig. 7 is a cross-sectional view of the absorbent article (1) taken along the line 1B-1B in Fig. 1 in an unfolded state. Fig. 8 is a cross-sectional view taken along the line 1B-1B in Fig. 1 in an unfolded state with the leak-prevention gather (60) standing up. Fig. 9 is a cross-sectional view taken along the line 1C-1C in Fig. 1 in an unfolded state. Fig. 10 is a cross-sectional view taken along the line 1C-1C in Fig. 1 in an unfolded state.

The leak-prevention gather (60) is composed of a side sheet (15) and a leak-prevention elastic member (61). The leak-prevention gather (60) has a contraction portion (62) that stands up by contraction of the leak-prevention elastic member (61), a first starting point portion (63) that is located outside the contraction portion (62) in the width direction (W) and serves as a starting point for the standing of the contraction portion, and a second starting point portion (64) that is located outside the contraction portion (62) in the front-back direction (L) and serves as a starting point for the standing of the contraction portion. As shown in Fig. 1, an inner edge (64I) of the second starting point portion (64) is located inside the inner edge (63I) of the first starting point portion (63) in the width direction (W). The inner edge (63I) of the first starting point (63) is positioned further outside in the width direction (W) than the absorbent core (31) in a region inside the front-back direction (L) of the second starting point (64). In addition, the region inside the front-back direction (L) of the second starting point (64) includes a central region (S3). The inner edge (64I) of the second starting point (64) is positioned in a region overlapping the absorbent core (31). The outer edge (63E) of the first starting point (63) coincides with the outer edge (64E) of the second starting point (64). In addition, in another form, the outer edge (63E) of the first starting point (63) may be positioned further outside in the width direction (W) than the outer edge (64E) of the second starting point (64). In addition, in the second starting point (64), the side sheet (15) and the surface sheet (10) are configured by two rows of bonding areas spaced apart in the width direction. The inner edge of the starting point configured by the multiple rows of bonding areas is the inner edge of the bonding area of the row located most inside in the width direction. In addition, the outer edge of the starting point configured by the multiple rows of bonding areas is the outer edge of the bonding area of the row located most outside in the width direction.

The side sheet (15) is folded outward in the width direction (W) at the tip of the contraction portion (62) and is laminated in two layers, and a leak-preventing elastic member (61) is arranged between the two layers of the side sheets (15). The contraction portion (62) has an extension portion (621) that extends inward in the width direction (W) from a first starting point portion (63), and a fold-back portion (622) that is folded outward in the width direction from the inner edge of the extension portion (621) as a starting point. The fold-back portion (622) has the leak-preventing elastic member (61), and the extension portion (621) does not have the leak-preventing elastic member (61). The fold-back portion (622) is configured to be able to stand up with respect to the extension portion (621) in a central region (S3) as a flap region that extends in the width direction (W) from the flap portion (5). The fold-back fold portion (622) should preferably be configured to be able to stand up at least in the central region (S3), and in the present embodiment, it is configured to be able to stand up in a region on the inner side in the front-back direction than the second starting point portion (64). The fold-back fold portion (622) is arranged on the skin-facing side (T1) of the extension portion (621). The extension portion (621) and the fold-back fold portion (622) each have two layers of side sheets (15). The standing vertex of the leak-prevention gather (60) becomes the outer edge (tip) of the fold-back fold portion (622). The inner edge of the fold-back fold portion (622) coincides with the inner edge of the extension portion (621). The outer edge of the fold-back fold portion (622) may coincide with the outer edge of the extension portion (621). The outer edge of the folded portion (622) is positioned further outside in the width direction (W) than the outer edge of the absorbent core (31) in the unfolded state shown in Fig. 7.

As shown in FIGS. 7 and 8, in an area on the inner side in the front-back direction (L) from the second starting point (64), the fold-back portion (622) is not joined to the extension portion (621). Therefore, in an area on the inner side in the front-back direction (L) from the second starting point (64), the contracted portion (62) stands up toward the wearer with the inner edge of the first starting point (63) as the starting point. The standing peak of the anti-swelling gather (60) becomes the outer edge (tip) of the fold-back portion.

As shown in FIGS. 9 and 10, the area overlapping with the second starting point (64) has a leak-preventing joint (65) that joins the fold-back portion (622) and the extension portion (621), and a leak-preventing non-joined portion (66) that is located on the outer side in the width direction (W) of the leak-preventing joint (65) and where the fold-back portion (622) and the extension portion (621) overlap without being joined. The leak-preventing joint (65) and the leak-preventing non-joined portion (66) are provided on the surface where the fold-back portion (622) and the extension portion (621) face each other. The leak-preventing joint (65) extends outward in the width direction (W) from the inner edge of the surface where the fold-back portion (622) and the extension portion (621) face each other. The outer edge (65E) of the leak-prevention joint (65) is positioned further outside the outer edge (31E) of the absorbent core (31) in the width direction (W). The leak-prevention non-joint (66) is provided between the outer edge of the leak-prevention joint (65) and the outer edge (622E) of the fold-back fold (622). That is, the leak-prevention non-joint (66) reaches the outer edge (622E) of the fold-back fold (622). Therefore, in the region overlapping with the second starting point (64), the fold-back fold (622) of the shrinkage portion (62) stands up toward the wearer based on the outer edge of the leak-prevention joint (65).

As shown in Fig. 2, the absorbent article (1) has an adhesive portion (70) provided on the non-skin-facing side (T2) of the back sheet (20). The adhesive portion (70) is a region provided with an adhesive for fixing the absorbent article (1) to a wearable article such as underwear.

The adhesive portion (70) may have a main body adhesive portion (71), a wing adhesive portion (72), and a hip flap adhesive portion (73). The wing adhesive portion (72) constitutes the flap adhesive portion of the present invention. The main body adhesive portion (71) is arranged on the non-skin-facing side (T2) of the main body portion (2) and has an adhesive that fixes the main body portion (2) to underwear. The main body adhesive portion (71) is provided in an area overlapping the absorbent core (31) in the thickness direction (T) of the absorbent article (1). It is preferable that the main body adhesive portion (71) extends continuously or intermittently from at least the central area (S3) to the rear of the absorbent article (1). The main body adhesive portions (71) extend in the front-back direction (L) and are provided in multiple numbers at intervals in the width direction (W). The main body adhesive portions (71) of the present embodiment are arranged in groups of four with the center of the width direction of the main body portion (2) interposed between them.

The main body adhesive portion (71) is covered by a main body release sheet (75). The main body release sheet (75) is arranged between the packaging sheet (100) and the absorbent article (1). The main body release sheet (75) is bonded to the inner surface of the packaging sheet (100) via the main body fixing portion (91). The main body adhesive portion (71) and the main body release sheet (75) are arranged across the first fold line (FL1), the second fold line (FL2), and the third fold line (FL3). As shown in Fig. 2, a plurality of main body fixing portions (91) are arranged at intervals in the front-back direction (L). The main body fixing part (91) has a first main body fixing part (911) provided in the first region (R11), a second main body fixing part (912) arranged in the second region (R12), a third main body fixing part (913) arranged in the third region, and a fourth main body fixing part (914) arranged in the fourth region (R14). In addition, the main body fixing part (91) preferably has at least the first main body fixing part (911).

The wing adhesive portion (72) is arranged on the skin-facing side (T2) of the wing (3) and has an adhesive that fixes the wing (3) to underwear. As shown in Fig. 2, the wing adhesive portion (72) has a first wing adhesive portion (721) and a second wing adhesive portion (722). The first wing adhesive portion (721) constitutes a first flap adhesive portion, and the second wing adhesive portion (722) constitutes a second flap adhesive portion. The second wing adhesive portion (722) is located on the inner side (the base side of the wing) in the width direction than the first wing adhesive portion (721) in the unfolded state of the absorbent article (1). The hip flap adhesive portion (73) is arranged on the non-skin-facing side (T2) of the hip flap (4) and has an adhesive that fixes the hip flap (4) to underwear. The front edge of the first wing adhesive portion (721) may be arranged further back than the front edge of the second wing adhesive portion (722). The rear edge of the first wing adhesive portion (721) may coincide with the rear edge of the second wing adhesive portion (722) in the front-back direction.

The length of the first wing adhesive portion (721) in the front-back direction may be longer than the length of the second wing adhesive portion (722) in the front-back direction. In addition, the area of the first wing adhesive portion (721) is larger than the area of the second wing adhesive portion (722). In the unfolded state of the package, the area of the wing adhesive portion (72) in an area inner than the center in the width direction (W) of the wing (3) may be larger than the area of the wing adhesive portion (72) in an area outer than the center in the width direction of the wing. The area inner than the center in the width direction (W) of the wing (3) is close to the flap fold line (FL5), and wrinkles or twists are likely to occur due to the folding of the wing (3). By increasing the area of the wing adhesive portion (72) in the area inner than the center in the width direction (W) of the wing (3), wrinkles or twists in the vicinity of the flap folding line (FL5) can be suppressed, and wrinkles or the like can be suppressed from occurring in the wing adhesive portion (72). In addition, by suppressing the twisting of the wing (3), problems such as wing adhesive portions (72) sticking to each other or wing adhesive portions (72) sticking to unintended areas can be suppressed.

The wing adhesive portion (72) and the hip flap adhesive portion (73) may be spaced apart from the flap fold line (FL5) in the width direction (W). The vicinity of the flap fold line (FL5) is prone to wrinkles or twists due to the folding of the wing (3) and the hip flap (4). Since the wing adhesive portion (72) and the hip flap adhesive portion (73) are spaced apart from the flap fold line (FL5) in the width direction (W), it is possible to suppress unintentional adhesion of the wing adhesive portion (72) or the hip flap adhesive portion (73) due to the wrinkles, etc. In addition, by suppressing twisting of the wing (3), it is possible to suppress problems such as wing adhesive portions (72) sticking to each other or hip flap adhesive portions (73) sticking to each other, or wing adhesive portions (72), etc. sticking to unintended areas.

In the wing (3), the rigidity of the region where the wing adhesive portion (72) is not provided is lower than the rigidity of the region where the wing adhesive portion (72) is provided. Similarly, in the hip flap (4), the rigidity of the region where the hip flap adhesive portion (73) is not provided is lower than the rigidity of the region where the hip flap adhesive portion (73) is provided. By providing regions with relatively low rigidity between the wing adhesive portion (72) and the flap fold line (FL5) and between the hip flap adhesive portion (73) and the flap fold line (FL5), deformation due to folding of the wing (3) or the like in those regions can be absorbed, and wrinkles or the like can be suppressed from occurring in the wing adhesive portion (72) or the hip flap adhesive portion (73). In addition, by suppressing twisting of wings (3), etc., it is possible to suppress problems such as wing adhesive parts (72) sticking to each other or hip flap adhesive parts (73) sticking to each other or wing adhesive parts (72) sticking to unintended areas.

As shown in Fig. 3, when the wing (3) and the hip flap (4) are folded on the skin-facing side (T1) of the main body (2), the wing adhesive portion (72) and the hip flap adhesive portion (73) are arranged on the surface side (opposite to the side facing the packaging sheet (100)) of the absorbent article (1) and are covered by a flap peeling sheet (76). When the wing (3) is folded on the skin-facing side (T1) of the main body (2), the pair of wing adhesive portions (72) are spaced apart from each other. Similarly, when the hip flap (4) is folded on the skin-facing side (T1) of the main body (2), the pair of hip flap adhesive portions (73) are spaced apart from each other.

The flap release sheet (76) covers a pair of wing adhesive portions (72). In addition, the flap release sheet (76) is arranged across the second fold line (FL2) and covers both the wing adhesive portion (72) and the hip flap adhesive portion (73). In another embodiment, the flap release sheet (76) may be arranged to cover only the wing adhesive portion (72). It is preferable that at least a portion of the wing adhesive portion (72) and the flap release sheet (76) be arranged closer to the front edge (110F) of the package than the second fold line (FL2).

The packaging sheet (100) extends toward the rear edge side from the first folding line (FL1), and in the third folded state, the flap peeling sheet (76) and the outer surface (100B) of the packaging sheet (100) face each other. The flap peeling sheet (76) is, in the third folded state, joined to the outer surface (100B) of the packaging sheet (100) via the flap fixing portion (92). The flap fixing portion (92) is arranged toward the front edge (110F) of the packaging body (110) from the second folding line (FL2), and in the third folded state, is arranged in an area where the packaging sheet (100) and the flap peeling sheet (76) face each other.

As shown in Fig. 12, in the packaging state, the outer surface (100B) of the packaging sheet (100) is joined to the flap peeling sheet (76) via the flap fixing portion (92), and the inner surface (100T) of the packaging sheet (100) is joined to the body peeling sheet (75) via the body fixing portion (91). The body fixing portion (91) and the flap fixing portion (92) overlap in the thickness direction (T). It is preferable that at least a part of the body fixing portion (91) and at least a part of the flap fixing portion (92) overlap.

In addition, although the flap release sheet (76) of the present embodiment is arranged across a pair of wing adhesive portions (72), in another form, the flap release sheet (76) may be separated in the width direction and arranged to cover each wing adhesive portion (72). In a configuration in which the flap release sheet (76) covers each wing adhesive portion (72), the flap fixing portion (92) may be provided on each flap release sheet (76).

The bonding strength of the packaging sheet (100) and the body peeling sheet (75) by the body fixing portion (91) is higher than the bonding strength of the body peeling sheet (75) and the absorbent article by the body adhesive portion (71). Therefore, when the body peeling sheet (75) is pulled through the packaging sheet during use, the packaging sheet (100) and the body peeling sheet (75) are not peeled off, and the body peeling sheet (75) is separated from the absorbent article (1) and the body adhesive portion (71).

Likewise, the bonding strength of the packaging sheet (100) and the flap peeling sheet (76) by the flap fixing portion (92) is higher than the bonding strength of the flap peeling sheet (76) and the absorbent article (1) by the wing adhesive portion (72). Therefore, when the flap peeling sheet (76) is pulled through the packaging sheet during use, the packaging sheet (100) and the flap peeling sheet (76) are not peeled off, and the flap peeling sheet (76) is separated from the absorbent article and the main body adhesive portion (71).

In addition, the bonding strength of the tag tape (102) and the packaging sheet (100) may be higher than the strength of the main body fixing part (91) that bonds the packaging sheet (100) and the main body peeling sheet (75). Therefore, the packaging body (110) can be unfolded while holding the tag tape (102) without damage to the main body fixing part (91) that bonds the packaging sheet (100) and the main body peeling sheet (75).

The bonding strength of the tag tape (102) and the packaging sheet (100) may be higher than the bonding strength of the main body peeling sheet (75) and the main body adhesive portion (71). In addition, the bonding strength of the tag tape (102) and the packaging sheet (100) may be higher than the bonding strength of the flap peeling sheet (76) and the wing adhesive portion (72). As described below, according to the packaging body of the present embodiment, the user can start to unfold the packaging body (110) near the tag tape (102) and the shear edge of the absorbent article (1) by grasping them, and can separate the packaging sheet (100) and the absorbent article without moving his/her hand until the unfolding is completed. At this time, since the bonding strength of the tag tape (102) and the packaging sheet (100) is higher than the bonding strength of the main body peeling sheet (75) and the main body adhesive portion (71), the main body adhesive portion (71) and the main body peeling sheet (75) can be peeled off through the packaging sheet (100) while maintaining the bonding of the tag tape (102) and the packaging sheet (100). Similarly, since the bonding strength of the tag tape (102) and the packaging sheet (100) is higher than the bonding strength of the flap peeling sheet (76) and the wing adhesive portion (72), the wing adhesive portion (72) and the flap peeling sheet (76) can be peeled off through the packaging sheet (100) while maintaining the bonding of the tag tape (102) and the packaging sheet (100).

Continuing, with reference to FIGS. 11 to 20, the unfolding manner when using the packaging body will be described. FIG. 11 is a perspective view of a packaging state in which absorbent articles (1) are individually packaged by packaging sheets (100). FIG. 12 is a cross-sectional view taken along line 11A-11A shown in FIG. 11. FIGS. 13 to 17 are drawings explaining the unfolding process in a cross-section based on line 11A-11A shown in FIG. 11. FIG. 13 shows a packaging body (110) of unfolding steps 2 and 3. FIG. 14 shows a packaging body (110) of unfolding step 4. FIG. 15 shows a packaging body (110) of unfolding step 5. FIG. 16 shows a packaging body (110) of unfolding steps 6 and 7. FIG. 17 shows a packaging body (110) of unfolding step 7. Fig. 18 is a drawing showing a packaging body (110) in the unfolding process 4. Fig. 19 is a cross-sectional view taken along line 13A-13A in Fig. 13. Figs. 20 to 22 are drawings showing a packaging body in the unfolding process 4 in cross-sections taken along line 13A-13A in Fig. 13. In addition, for convenience of explanation, in Figs. 19 and 20, the leak-prevention gather is omitted, and in Figs. 21 and 22, the leak-prevention gather (60) is shown. In addition, the unfolding modes shown below are examples, and may be unfolded in other modes by a user.

The user first unfolds the package (110) in the packaging state shown in Figs. 11 and 12 by pulling the tag tape (102) and unfolding the absorbent article (1) and the packaging sheet (100) with the third fold line (FL3) as the starting point (unfolding process 1). Fig. 13 shows the package (110) in the third folded state, folded with the first fold line (FL1) and the second fold line (FL2) as the starting point, and not folded by the third fold line (FL3).

The user then continues to peel the packaging sheet (100) from the main body adhesive portion (71) (development process 2). More specifically, as shown in Fig. 13, the front edge (100F) of the packaging sheet (100) is moved in the rotational direction (X131) with the second fold line (FL2) as the center, thereby moving the packaging sheet (100) away from the main body adhesive portion (71). At this time, the main body peeling sheet (75) is joined to the packaging sheet (100) by the main body fixing portion (91), and therefore moves together with the packaging sheet (100). In Fig. 13, the packaging sheet (100) and the main body peeling sheet (75) in the development process 2 are indicated by a dashed line.

The user peels the packaging sheet (100) from the main body adhesive portion (71) to the vicinity of the second folding line (FL2), and then moves the packaging sheet (100) in a rotational direction (X132) centered on the first folding line (FL1) so as to move the packaging sheet (100) away from the main body adhesive portion (71) (unfolding step 3). In Fig. 13, the packaging sheet (100) and the main body peeling sheet (75) in the unfolding step 3 are shown in solid lines.

As shown in Fig. 14, the user subsequently unfolds the packaging sheet (100) and the absorbent article (1) from the second fold line (FL2) as a starting point (unfolding step 4). In the unfolding step 4, the packaging body (110) is unfolded from the third folded state to the second folded state. In the third folded state folded from the second fold line (FL2), the packaging sheet (100) and the flap release sheet (76) are joined via the flap fixing portion (92). Therefore, when the packaging body (110) is unfolded from the third folded state to the second folded state, the flap release sheet (76) is pulled away from the wing adhesive portion (72) via the packaging sheet (100). More specifically, the user moves the packaging sheet (100) in the rotational direction (X14) centered on the second fold line (FL2). Thereby, as shown in Fig. 14, the packaging sheet (100), the main body (2), and the flap peeling sheet (76) move in the rotational direction (X14), so that the flap peeling sheet (76) moves away from the wing adhesive portion (72). Fig. 14 shows a state in which the flap peeling sheet moves in the rotational direction like the packaging sheet, so that the flap peeling sheet is away from the wing adhesive portion (72).

The user also further pulls the packaging sheet (100) so that the packaging sheet (100) and the absorbent article (1) are unfolded without being folded at the second fold line (FL2) (unfolding step 5). In the state shown in Fig. 15, only the flap release sheet (76) is folded at the second fold line (FL2), and the other members are in a first folded state that is not folded at the second fold line (FL2). In this state, the flap release sheet (76) is in contact with the hip flap adhesive portion (73) located in the second region (R12). In the cross-section shown in Fig. 15, the hip flap adhesive portion (73) is not shown, but a position corresponding to the hip flap adhesive portion (73) is virtually shown.

The user then moves the packaging sheet (100) in the rotational direction (X161) with the first fold line (FL1) as a starting point, as shown in Fig. 16 (unfolding process 6). At this time, the main body peeling sheet (75) and the flap peeling sheet (76) arranged with the packaging sheet (100) interposed therebetween move in the rotational direction (X161) with the first fold line (FL1) as a starting point. In the first region (R11), the main body peeling sheet (75) is peeled from the main body adhesive portion (71). At this time, the flap peeling sheet (76) located at the rear edge side relative to the second fold line (FL2) is in contact with the hip flap adhesive portion (73) of the second region (R12). Therefore, when the user further pulls the packaging sheet (100), the packaging body (110) moves in the rotational direction (X162) (Fig. 16) and the rotational direction (X17) (Fig. 17) with the first fold line (FL1) as the starting point (unfolding process 7). Fig. 17 shows a state in which the area of the rear edge side of the packaging sheet (100) and the absorbent article (1) relative to the first fold line (FL1) moves in the rotational direction (X17) with the first fold line (FL1) as the starting point. The user can peel off the main body peeling sheet (75) and the flap peeling sheet (76) together with the packaging sheet (100) to expose the main body adhesive portion (71), the wing adhesive portion (72), and the hip flap adhesive portion (73). According to this method of unfolding, the user can start unfolding by holding the packaging (110) near the tag tape (102) and the shear edge of the absorbent article (1), and separate the packaging sheet (100) and the absorbent article without holding the hand until unfolding is completed.

The aforementioned unfolding process 4 can, depending on the user, grip the packaging sheet (100) and the absorbent article (1) near the first fold line (FL1) and rotate the packaging body near the first fold line (FL1) with the second fold line (FL2) as the starting point. When unfolded in this manner, the force for unfolding the packaging sheet (100) is easily transmitted to the flap fixing portion (92), so that the flap peeling sheet (76) can be easily peeled from the wing adhesive portion (72).

However, depending on the user, in the aforementioned unfolding process 4, the shear edge (100F) side of the packaging sheet (100) is gripped and the packaging sheet (100) is pulled and unfolded, continuing from the previous unfolding process 3. Specifically, for example, the shear edge (1F) of the absorbent article (1) is gripped with one hand, and the shear edge (100F) of the packaging sheet (100) is gripped with the other hand, so that the packaging sheet (100) is peeled from the main body adhesive portion (71) in the region between the first fold line (FL1) and the shear edge (1F) of the absorbent article (1) (unfolding process 3), and the packaging sheet (100) and the absorbent article (1) are gripped as they are, and force is applied to the first fold line (FL1) through the packaging sheet (100) to unfold the packaging body (110) (unfolding process 4). The packaging body (110) of the absorbent article according to the present embodiment is configured so that, when the packaging sheet (100) is gripped in the unfolding step 4 and the packaging body (110) is unfolded, the main body peeling sheet (75) can be easily peeled from the main body adhesive portion (71), and the flap peeling sheet (76) can be easily peeled from the wing adhesive portion (72).

As described above, in the unfolding process 4, when force is applied to the first fold line (FL1) through the packaging sheet (100), the packaging body (110) moves in the rotational direction (X14) (Fig. 14) with the first fold line (FL1) side centered on the second fold line (FL2), and along with the movement, the flap release sheet (76) moves in the rotational direction (X14) together with the packaging sheet (100), so that the flap release sheet (76) separates from the wing adhesive portion (72) in the third region (R13).

When moving the first fold line (FL1) side in the rotational direction (X14) with the second fold line (FL2) side as the center, it is necessary to move not only the packaging sheet (100) but also the entire absorbent article (1) in the rotational direction. Even if force is applied only to the packaging sheet (100), if the absorbent article (1) does not move in the rotational direction (X14), force that moves in the front-back direction (L) is applied only to the packaging sheet (100), and the flap release sheet (76) cannot be pulled in the direction away from the wing adhesive portion (72) via the flap fixing portion (92). As a result, shear stress is generated by the wing adhesive portion (72) in contact with the flap release sheet (76), and there is a concern that it will be difficult for the flap release sheet (76) to separate from the wing adhesive portion (72) in the third region (R13).

In the packaging body (110) according to the present embodiment, the force applied to the packaging sheet (100) is transmitted to the body peeling sheet (75) through the body fixing portion (91). This is because the body peeling sheet (75) is in contact with the body adhesive portion (71) and thus easily transmits force to the absorbent article (1). When a user applies force through the packaging sheet (100) with the first fold line (FL1) side facing the rotational direction (X14), the force is transmitted to the body peeling sheet (75) through the body fixing portion (91), so that the first fold line (FL1) side of the absorbent article (1) easily moves in the rotational direction (X14).

The main body fixing portion (91) overlaps the flap fixing portion (92) in the thickness direction (T). Therefore, force is transmitted from the packaging sheet (100) to the main body peeling sheet (75) and the absorbent article (1) through the main body fixing portion (91), and when the packaging sheet (100) and the main body peeling sheet (75) move in the rotational direction (X14), the flap peeling sheet (76) also easily moves in the rotational direction (X14), so that the flap peeling sheet (76) can be easily peeled from the wing adhesive portion (72). Therefore, the main body peeling sheet (75) can be easily peeled from the main body adhesive portion (71), and the flap peeling sheet (76) can be easily peeled from the wing adhesive portion (72).

The main body fixing portion (91) and the flap fixing portion (92) may be arranged closer to the first fold line (FL1) than the center of the front-back direction (L) of the second fold line (FL2) and the first fold line (FL1) when the packaging body (110) is in a third folded state where it is folded based on the first fold line (FL1) and the second fold line (FL2). The center of the front-back direction (L) of the second fold line (FL2) and the first fold line (FL1) becomes the center of the front-back direction of the third region (R13). Since the main body fixing portion (91) and the flap fixing portion (92) are spaced apart from the second fold line (FL2) which becomes the rotational axis in the unfolding step 4, the first fold line (FL1) side easily moves in the rotational direction centered on the second fold line (FL2) in the unfolding step 4. In addition, it is preferable that at least a part of the main body fixing portion (91) and at least a part of the flap fixing portion (92) are arranged closer to the first fold line (FL1) than the center of the front-back direction (L) of the second fold line (FL2) and the first fold line (FL1). More preferably, it is preferable that the main body fixing portion (91) and the flap fixing portion (92) are arranged closer to the first fold line (FL1) than the center of the front-back direction (L) of the second fold line (FL2) and the first fold line (FL1).

The flap fixing portion (92) may overlap, in the thickness direction (T), an area between a pair of wing adhesive portions (72) when the packaging body (110) is in a third folded state in which the first fold line (FL1) and the second fold line (FL2) are the starting point. When the flap release sheet (76) moves away from the wing adhesive portion (72) in the unfolding process 4, the area of the flap release sheet (76) that comes into contact with the flap fixing portion (92) moves first, and the area of the flap release sheet (76) that comes into contact with the wing adhesive portion (72) follows and moves. This is because the wing adhesive portion (72) and the flap fixing portion (92) do not overlap. As shown in FIG. 18 and FIG. 20, the tip of each wing (3) moves in the rotational direction (X18) with the origin of each wing as the starting point, and stands up from the skin-facing side (T1) of the absorbent article (1). The pair of wings (3) and the main body (2) are arranged to surround an approximately triangular space.

In a state where the wing (3) and the main body (2) are arranged to form a triangle, the center of the width direction (W) of the flap release sheet (76) (the portion overlapping with the flap fixing portion (92)) is pulled toward the packaging sheet (100), so that the flap release sheet (76) is bent. However, the flap release sheet (76) tries to maintain a flat state by being pulled together with the packaging sheet (100). Therefore, in the unfolding process 4, the flap release sheet (76) moves in a state where the tip of the wing (3) is deformed to stand up from the base of the wing, so that the outer edge of the wing adhesive portion (72) in the first folded state begins to peel from the flap release sheet (76). The flap release sheet (76) gradually separates from the wing adhesive portion (72), so that the flap release sheet (76) can be easily peeled from the wing adhesive portion (72).

The length in the width direction (W) of the flap fixing portion (92) may be shorter than the length in the width direction (W) of the main body fixing portion (91). When the tip of each wing (3) is deformed to stand up with respect to the base of the wing (3) in the unfolding process 4, the tip of each wing can be further pulled toward the center of the width direction (W) of the main body portion (2) to increase the standing angle of the wing (3). Therefore, the flap peeling sheet (76) can be peeled off more easily from the wing adhesive portion (72).

In another form, the length in the width direction (W) of the flap fixing portion (92) may be longer than the length in the width direction (W) of the main body fixing portion (91). In the unfolding process 4, the flap release sheet (76) can be pulled in the unfolding direction over a wide range in the width direction through the flap fixing portion (92). Accordingly, the flap release sheet (76) can be peeled from the wing adhesive portion (72).

The flap fixing portion (92) may be arranged spaced apart from the wing adhesive portions (72) in the width direction in the region between the pair of wing adhesive portions (72). When the tip of each wing (3) is deformed to stand up with respect to the base of the wing (3) in the unfolding process 4, the standing angle of the wing (3) can be further increased. Therefore, the flap peeling sheet (76) can be peeled off more easily from the wing adhesive portions (72).

The front edge of the first wing adhesive portion (721) may be arranged further back than the front edge of the second wing adhesive portion (722). The front edge, which is the edge on the second short edge side of the wing adhesive portion (72), becomes the side away from the second folding line (FL2), which becomes the starting point of unfolding in the unfolding step 4. The second wing adhesive portion (722) located on the base side of the wing (3) extends further from the second folding line (FL2) than the first wing adhesive portion (721) located on the leading end side of the wing (3). In the first folded state in which the wing (3) is folded toward the skin-facing side of the main body (2), the wing adhesive portion located on the inner side in the width direction has a shorter length in the front-back direction. Therefore, when the tip of each wing (3) is deformed to stand up with respect to the base of each wing (3), the tip side of the wing (3) is likely to stand up earlier than the base side of the wing (3). By increasing the standing angle of the wing (3), the outer edge of the wing adhesive portion (72) and the flap release sheet (76) are gradually separated, so that the flap release sheet (76) can be more easily separated from the wing adhesive portion (72).

In addition, the second side low unit weight region (R41) of the low unit weight portion (34) may extend in the front-back direction (L) on the shear edge side relative to the second fold line (FL2). The absorbent core (31) in the region on the shear edge side relative to the second fold line (FL2) forms a deformation starting point extending in the front-back direction (L) by the second side low unit weight region (R41), and becomes easy to bend in the width direction (W). Therefore, in the unfolding process 4, when the wing (3) is pulled via the flap release sheet (76) and the wing adhesive portion (72), the center of the width direction (W) of the region on the shear edge side relative to the second fold line (FL2) is deformed so as to be separated from the flap release sheet (76). The absorbent core (31) in the region on the shear edge side relative to the second fold line (FL2) is deformed into a curved shape. Thereby, as shown in Fig. 18, the base of the wing (3) located in the region on the front edge side from the second folding line (FL2) moves inward in the width direction (W), so that the standing angle of the wing (3) increases. Therefore, the tip of each wing stands up with the base of each wing as the starting point, and the pair of wings (3) and the main body (2) are arranged to surround an approximately triangular space. As described above, the outer edge of the wing adhesive portion (72) in the first folded state begins to peel off from the flap peeling sheet (76). The flap peeling sheet (76) gradually separates from the wing adhesive portion (72), so that the flap peeling sheet (76) can be easily peeled off from the wing adhesive portion (72).

In addition, the front and rear low-unit-weight regions (R42) of the low-unit-weight portion (34) do not have to be provided in the first region (R11) on the rear edge side relative to the first fold line (FL1) in the unfolded state. In the unfolding process 4, when unfolding with the second fold line (FL2) as the starting point, the region on the first fold line (FL1) side relative to the second fold line (FL2) is moved in the rotational direction with respect to the region on the front edge side relative to the second fold line (FL2). At this time, since the region between the first fold line (FL1) and the flap fixing portion (92) is difficult to deform inwardly in the width direction, the region on the front edge side relative to the second fold line (FL2) is relatively easy to deform inwardly in the width direction. Therefore, when the wing (3) is pulled through the flap release sheet (76) and the wing adhesive portion (72), the root of the wing moves inward in the width direction (W), so that the standing angle of the wing (3) tends to increase. Therefore, the flap release sheet (76) can be easily peeled from the wing adhesive portion (72).

In another form, the front and rear low unit weight regions (R42) do not have to be provided in the second region (R12). That is, the front and rear low unit weight regions (R42) do not have to be provided in the region between the first fold line (FL1) and the second fold line (FL2) in the deployed state. Since the front and rear low unit weight regions (R42) are not provided in both the first region (R11) and the second region (R12), in the deployed process 4, the region on the first short edge side is more difficult to deform than the second fold line (FL2), and the region on the front edge side is relatively more likely to deform inward in the width direction (W) than the second fold line (FL2). Therefore, when the wing (3) is pulled via the flap peeling sheet (76) and the wing adhesive portion (72), the base portion of the wing (3) moves inward in the width direction, so that the standing angle of the wing (3) tends to increase. Accordingly, the standing angle of the wing (3) becomes larger, so that the flap peeling sheet (76) can be easily peeled from the wing adhesive portion (72).

The second side low-unit weight region (R41) and the flap fixing portion (92) may be arranged closer to the first fold line (FL1) than the center of the front-back direction (L) between the second fold line (FL2) and the first fold line (FL1) when the packaging body (110) is in a third folded state with the first fold line (FL1) and the second fold line (FL2) as the starting point. Since the flap fixing portion (92) is away from the second fold line (FL2), which becomes the rotation axis when unfolding with the second fold line (FL2) as the starting point, it becomes easy to move the flap peeling sheet (76) in the unfolding direction by pulling the packaging sheet (100) during unfolding. At this time, since the deformation starting point due to the second side low-unit weight region (R41) is provided on the first folding line (FL1) side, the standing angle of the wing (3) can be further increased on the first folding line (FL1) side.

The first side low unit weight region (R43) of the low unit weight section (34) may extend outward in the width direction (W) toward the first fold line (FL1) in the region between the first fold line (FL1) and the flap fixing portion (92) in the unfolded state. A deformation starting point that extends outward in the width direction (W) toward the first fold line (FL1) is formed in the region between the first fold line (FL1) and the flap fixing portion (92). When viewed in the cross-section in the thickness direction, the absorbent core (31) on the flap peeling sheet side relative to the flap fixing portion (92) has a deformation starting point that extends outward in the width direction (W) from the flap fixing portion (92) toward the first fold line (FL1) due to the deformation starting point by the first side low unit weight region (R43). Accordingly, when the flap release sheet (76) is pulled through the packaging sheet (100) in the unfolding process 4, a deformation starting point is formed in the flap release sheet (76) that extends outward in the width direction (W) from the flap fixing portion (92) toward the first fold line (FL1). The flap release sheet (76) is deformed to separate from the wing adhesive portion (72), so that the flap release sheet (76) can be easily peeled from the wing adhesive portion (72).

The packaging body of the present embodiment is configured so as to suppress the problem of unintentional adhesion of the wing adhesive portion (72) as the flap adhesive portion in the fourth unfolded state. Specifically, the outer edge (622E) of the fold-back fold portion (622) may be arranged on the outer side in the width direction from the absorbent core (31). The fold-back fold portion (622) of the contracted portion (62) has a leak-preventing elastic member (61), and in the central region (S3), the outer side in the width direction also stands up toward the wearer, starting from the inner edge of the extension portion (621).

As shown in Fig. 21, when the wing (3) is folded with the flap fold line (FL5) as the starting point, a leak-prevention gather (60) is arranged between the wing (3) and the main body (2) arranged with the flap fold line (FL5) in between. Therefore, the inner surface (the skin-facing surface side in the unfolded state) of the wing (3) in the folded state is arranged to face the outer edge (622E) of the folded portion (622). As shown in Fig. 22, in the unfolding step 4, when the wing (3) is pulled together with the flap peeling sheet (76) and moves inward (X221) in the width direction (W), the outer edge (622E) of the folded portion (622) comes into contact with the inner surface of the wing (3), thereby restricting the movement of the wing (3) inward in the width direction. Fig. 22 shows a state in which the outer edge (622E) of the folded-back portion (622) is in contact with the inner surface of the wing (3). The outer edge (622E) of the folded-back portion (622) is positioned on the outer side in the width direction relative to the absorbent core (31), and presses the wing (3) toward the wearer also on the outer side in the width direction near the outer edge (31E) of the absorbent core (31) (X222). Therefore, by suppressing the twisting of the wing (3) in the unfolding process 4, it is possible to suppress problems such as wing adhesive portions (72) sticking to each other or wing adhesive portions (72) sticking to unintended areas.

The inner edge (63I) of the first starting point (63) may be arranged on the outer side in the width direction (W) of the absorbent core (31) in the central region (S3). The standing point of the entire contraction portion (62) in the central region (S3) becomes the first starting point (63). Since the inner edge of the first starting point (63) is positioned on the outer side in the width direction (W) of the absorbent core (31), when the wing (3) attempts to move inward in the width direction, the contraction portion (62) easily comes into contact with the inner surface of the wing (3) in the first folded state. Accordingly, the flap portion can be pressed toward the outer side in the width direction, and twisting of the wing in the unfolding process 4 can be suppressed.

In addition, the inner edge (64I) of the second starting point portion (64) may be arranged in an area overlapping the absorbent core (31). The second starting points (64) are provided in a pair with a gap in the front-back direction, and the area between the second starting points (64) in the front-back direction (L) stands up with the second starting point portion (64) as the starting point. Since the second starting point portion (64) is overlapped on the absorbent core (31) having relatively high rigidity, the standing point by the second starting point portion (64) becomes stable, and the contraction portion (62) stands up more easily in the area between the second starting points (64) in the front-back direction (L).

The flap fixing portion (92) overlaps an area between a pair of wing adhesive portions (72) in the thickness direction (T), and may be spaced apart from the wing adhesive portions (72). In the unfolding process 4, when the user pulls the packaging sheet (100), the flap peeling sheet (76) moves in the unfolding direction away from the wing adhesive portions (72) in the thickness direction (T) (X162 in FIG. 16, X17 in FIG. 17). At this time, since the wing adhesive portion (72) is spaced apart from the flap fixing portion (92) in the width direction (W), it is difficult to move in the unfolding direction together with the flap fixing portion (92), and it is easy to maintain a flat state. Accordingly, in the unfolding process 4, the flap peeling sheet (76) is easily peeled off from the wing adhesive portion (72), so that problems such as the wing adhesive portions sticking to each other or the wing adhesive portion (72) sticking to an unintended area can be suppressed.

The non-joined portion (66) of the anti-sewage gather (60) may reach the outer edge (622E) of the fold-back portion (922) in the unfolded state. The outer edge of the fold-back portion (622) is not joined to the extension portion (621) and stands up with respect to the extension portion (621). The fold-back portion (622) is made easier to stand up more toward the wearer on the outer side in the width direction (W), thereby urging the wing (3) toward the outer side in the width direction and restricting the movement of the wing (3) in the width direction (W).

The outer edge (65E) of the anti-slip joint (65) may be arranged further outside in the width direction (W) than the outer edge (31E) of the absorbent core (31). The standing point of the fold-backed portion (622) in the area overlapping the second starting point (64) becomes the outer edge (65E) of the anti-slip joint (65). Since the standing point of the fold-backed portion (622) is located further outside in the width direction (W) than the absorbent core (31), when the wing (3) in the fold-backed state tries to move inward in the width direction (W), the contraction portion (62) is likely to come into contact with the inner surface of the wing. By pressing the wing (3) toward the outside in the width direction, the movement of the wing (3) in the width direction can be restricted.

The leak-preventing elastic member (61) may be arranged on the outer side in the width direction (W) of the flap release sheet (76) in the first folded state. The area on the outer side in the width direction (W) of the flap release sheet (76) in the first folded state is not covered by the flap release sheet (76), and therefore has low rigidity and is prone to deformation. By providing the leak-preventing elastic member (61) of the fold-back portion (622) in the above area, it is possible to suppress the inward movement of the wing (3) in the width direction in the area having relatively low rigidity.

In the central region (S3), a low-unit weight portion (34) may be provided. Specifically, in the central region (S3), at least a first low-unit weight portion (341) extending in the front-back direction is provided. The low-unit weight portion (34) has a curved shape in which the center in the width direction protrudes toward the front side and extends in the front-back direction (L). The absorbent core (31) in the central region (S3) is easily bent with the first low-unit weight portion (341) as a starting point. More specifically, as shown in Fig. 22, when the wing (3) is pulled via the flap release sheet (76) and the wing adhesive portion (72), the center in the width direction (W) of the absorbent core (31) is deformed into a curved shape so as to be separated from the flap release sheet (76). By this, as shown in FIG. 18 and FIG. 22, the origin of the wing (3) located in the area on the shear edge side relative to the second folding line (FL2) moves inward in the width direction (W).

Therefore, in the unfolding process 4, the flap peeling sheet (76) moves in the unfolding direction while the origin of the wing (3) moves inward in the width direction (W) (X162 in Fig. 16, X17 in Fig. 17). At this time, the wing (3) is pressed outward in the width direction by the contraction portion (62), making it easy to maintain the wing adhesive portion (72) in a flat state. It is possible to suppress the formation of wrinkles or the like in the wing adhesive portion (72).

The low-unit weight portion (34) may overlap in the region between the pair of wing adhesive portions (72) in the thickness direction (T). The absorbent core (31) of the central region (S3) is easily bent with the low-unit weight portion (34) as the starting point between the pair of wing adhesive portions (72). Therefore, when the wing adhesive portion (72) is pulled through the flap release sheet (76), the wing (3) is more easily erected. At this time, the wing (3) is pressed outward in the width direction (W) by the contraction portion (62), so that the wing adhesive portion (72) is easily maintained in a flat state. Therefore, while suppressing the formation of wrinkles or the like in the wing adhesive portion (72), the flap release sheet (76) can be moved in the unfolding direction, and the flap release sheet (76) can be peeled from the wing adhesive portion (72).

The low-unit weight portion (34) may be provided in an area that does not overlap the main body adhesive portion (71) and the wing adhesive portion (72) when the package (110) is in an unfolded state. The area that does not overlap the main body adhesive portion (71) and the wing adhesive portion (72) is an area that is not bonded to underwear or the like when worn and is prone to deformation. By providing the low-unit weight portion (34) in the above area, the absorbent core (31) is more prone to deformation with the low-unit weight portion (34) as a starting point, and the wing (3) is more prone to standing up. The flap release sheet (76) and the wing (3) are prone to falling in the unfolded direction, and the flap release sheet (76) can be peeled from the wing adhesive portion (72) while suppressing twisting of the wing (3).

The packaging body of the present embodiment is configured so as to be able to absorb distortion of the absorbent article in the fourth unfolded state. Specifically, the second side low unit weight region (R41) may extend in the width direction (W) in a region on the shear edge side relative to the flap fixing portion (92) in the unfolded state. When unfolding from the second fold line (FL2) as a starting point, some users may have difficulty pulling the packaging sheet (100) approximately perpendicular to the shear edge (1F) of the absorbent article (1). When the shear edge (1F) of the absorbent article (1) is grasped with one hand and the packaging sheet (100) is pulled with the other hand, the flap fixing portion (92) to which force is applied via the packaging sheet (100) is pulled obliquely, causing distortion in the main body portion (2) in the region between the flap fixing portion (92) and the shear edge (1F) of the absorbent article (1). If distortion occurs in the main body (2) in the area between the flap fixing portion (92) and the shear edge (1F) of the absorbent article (1), it becomes difficult for the flap release sheet (76) and the wing adhesive portion (72) to move in the direction in which they are separated from each other. There is a concern that shear stress caused by the wing adhesive portion (72) may occur, making it difficult to smoothly separate the flap release sheet (76) from the wing adhesive portion (72).

Since the second side low unit weight region (R41) extends in the width direction (W) in the region on the side of the shear edge (second end edge) (1F) relative to the flap fixing portion (92), the second side low unit weight region (R41) can absorb distortion of the main body portion (2). Specifically, as shown in Fig. 23, the second side low unit weight region (R41) by the first low unit weight portion (341) is deformed, so that distortion in the front-back direction (L) and the width direction (W) can be absorbed. Fig. 23 is a drawing showing a deformation state of the absorbent core (31) as viewed from a plane of the absorbent article. Fig. 23 (a) is a state before deformation, and Fig. 23 (b) is a state after deformation. For example, with respect to the shear edge (1F) of the absorbent article, when the wing (3) is pulled upward and to the left in Fig. 21 through the flap fixing portion (92) and the packaging sheet (100), force is applied to the main body portion (2) sandwiched by the wing (3) toward the left and upward. As shown in Fig. 23 (b), when force is applied to the main body portion (2) toward the left and upward, the first low unit weight portion (341) is deformed. More specifically, force of symbol (X211) is applied to the left region of the main body portion (2), and force of symbol (X211) is applied to the right side of the main body portion. As a result, the first low unit weight portion (341) is deformed, so that the flap fixing portion (92) and the main body fixing portion (91) are tilted upward and to the left, thereby absorbing distortion of the flap fixing portion (92) and the wing adhesive portion (72). Fig. 24 is a perspective view of the packaging body (110) in the unfolding process 4, and schematically shows a state in which the distortion of the region on the shear edge side relative to the flap fixing portion (92) in the fourth unfolding process is absorbed. The symbol (22WCL) in Fig. 24 indicates the center of the width direction (W) of the main body portion (2). Even in a case where the packaging sheet cannot be pulled approximately vertically with respect to the shear edge of the absorbent article, the second-side low-unit-weight region (R41) absorbs the distortion, and the flap peeling sheet (76) can be pulled approximately vertically with respect to the wing adhesive portion (72). Therefore, the flap peeling sheet (76) can be easily peeled from the wing adhesive portion (72).

The second side low unit weight region (R41) may extend in the width direction (W) in the region between the flap fixing portion (92) and the first fold line (FL1) in the unfolded state. The region between the flap fixing portion (92) and the first fold line (FL1) is more likely to be subjected to force in the unfolding direction in the fourth unfolding process. Since the second side low unit weight region (R41) is provided in the region between the flap fixing portion and the first fold line (FL1), it is easy to further obtain the effect of absorbing distortion of the main body portion (2).

The second side low unit weight region (R41) may reach the outer edge of the absorbent core (31). The region on the front edge (1F) side of the absorbent article (1) and the region overlapping the flap fixing portion (92) can be divided by the second side low unit weight region (R41), making it easier to obtain the effect of absorbing distortion of the main body portion (2).

The main body fixing portion (91) may have a first main body fixing portion (911). The first main body fixing portion (911) is provided in the first region (R11) and is arranged on the first end edge side relative to the first fold line (FL1). Since the packaging sheet (100) and the main body release sheet (75) are joined at the first main body fixing portion (911) on the rear end edge side relative to the first fold line, when the packaging sheet (100) is pulled so as to be expanded from the second fold line (FL2) in the expansion step 4, it becomes easier to expand the absorbent article via the packaging sheet (100) and the main body release sheet (75). The first main body fixing portion (911) is positioned on the outer side of the movement direction with respect to the area to be moved (the area rearward of the second fold line) when the packaging body (110) is moved in the rotational direction (X14) of Fig. 14. Accordingly, it becomes easier to apply force to the entire moving area, and the package (110) can be moved more smoothly in the rotational direction (X14), thereby unfolding the package (110) based on the second folding line.

The main body fixing portion (91) may have a first main body fixing portion (911), and the low-unit-weight portion (34) may have an intermediate low-unit-weight portion (R44) located in a second region (R12) (region between the first folding line and the second folding line). A force applied to the packaging sheet (100) is transmitted to the main body peeling sheet (75) through the main body fixing portion (91). The main body peeling sheet (75) is in contact with the main body adhesive portion (71), and thus easily transmits force to the absorbent article (1). Therefore, when the user applies force to the first fold line (FL1) through the packaging sheet (100) in the third folded state, the force is transmitted to the main body peeling sheet (75) through the main body fixing part (91), so that the first fold line side of the main body portion (2) easily moves in the rotational direction (X162, X17) (Figs. 16 and 17) centered on the second fold line (FL2). When the first fold line side of the main body portion (2) moves in the rotational direction centered on the second fold line (FL2) in the third folded state, the absorbent core (31) of the second region (R12) deforms based on the intermediate low unit weight region (R44). As the absorbent core (31) of the second region (R12) is deformed, the flap release sheet (76) is deformed to follow the absorbent core (31) of the second region (R12), and the flap release sheet (76) is deformed to separate from the wing adhesive portion (72). Therefore, the flap release sheet (76) can be easily peeled off from the wing adhesive portion (72). The intermediate low unit weight region (R44) may be configured so that the absorbent core (31) of the second region (R12) is easily deformed, and may extend in the width direction or may extend in the front-back direction. More preferably, as in the present embodiment, the intermediate low unit weight region (R44) may extend in the width direction and also in the front-back direction. That is, the intermediate low unit weight region (R44) may be inclined in the width direction and also in the front-back direction. According to this configuration, the absorbent core of the second region (R12) is prone to bending in both the front-back and width directions, making it easier for the flap release sheet (76) to be further deformed to separate from the wing adhesive portion (72).

The main body fixing portion (91) may have a first main body fixing portion (911) and a second main body fixing portion (912). The second main body fixing portion (912) is arranged in the second region (R12) between the first fold line (FL1) and the second fold line (FL2) in the unfolded state of the package. The packaging sheet (100) and the main body peeling sheet (75) are joined by the main body fixing portion (91) in both the first region (R11) and the second region (R12). When the packaging sheet (100) is pulled so as to unfold from the second fold line (FL2), force can be applied to both sides of the first fold line (FL1), making it easier to unfold the absorbent article via the packaging sheet (100) and the main body peeling sheet (75).

The first main body fixing portion (911) and the second main body fixing portion (912) may overlap in the thickness direction (T) in the third folded state. It is preferable that at least a part of the first main body fixing portion (911) and at least a part of the second main body fixing portion (912) overlap. In the unfolding process 4, when force is applied to both sides across the first fold line by the first main body fixing portion (911) and the second main body fixing portion (912), the force is easily transmitted, making it easier to unfold the absorbent article through the packaging sheet and the main body peeling sheet.

On the front edge (1F) side of the absorbent article (1) beyond the third fold line (FL3), the boundary between the high-unit weight portion (33) and the mid-unit weight portion (35) may extend in the width direction (W). The boundary between the high-unit weight portion (33) and the mid-unit weight portion (35) is provided at the outer edge of the high-unit weight portion (33) in the width direction and the short edge of the high-unit weight portion (33) in the front-back direction (L). Among these, the boundary between the high-unit weight portion (33) and the mid-unit weight portion (35) located on the front side may extend in the width direction (W) ahead of the third fold line (FL3). The boundary between the high-unit weight portion (33) and the mid-unit weight portion (35) is prone to deformation due to a difference in rigidity caused by the difference in the unit weight of the absorbent material. The boundary between the high-unit weight portion (33) and the medium-unit weight portion (35) allows the main body portion (2) in the unfolding process 4 to absorb distortion. The area in front of the third fold line (FL3) is close to a portion of the packaging body that is held with one hand, such as the tag tape (102) of the packaging body. Therefore, distortion of the main body portion (2) can be absorbed in an area close to a portion that is held with the packaging body (110). Even when the packaging sheet (100) cannot be pulled approximately vertically with respect to the shear edge of the absorbent article, the boundary between the high-unit weight portion (33) and the medium-unit weight portion (35) absorbs distortion, and the flap release sheet (76) can be pulled approximately vertically with respect to the wing adhesive portion (72). Therefore, the flap release sheet (76) can be easily peeled from the wing adhesive portion (72).

In order to further obtain the effect of absorbing distortion due to the boundary between the high unit weight portion (33) and the medium unit weight portion (35), a low unit weight portion (34) extending in the width direction (W) may be provided in front of the boundary between the high unit weight portion (33) and the medium unit weight portion (35). The distortion of the main body portion (2) can be absorbed by the rigidity difference due to the boundary between the high unit weight portion (33) and the medium unit weight portion (35) and the deformation of the low unit weight portion.

In addition, in order to further obtain the effect of absorbing distortion due to the boundary between the high-unit weight portion (33) and the medium-unit weight portion (35), a non-adhesive portion where no adhesive portion (70) is provided may be provided so as to extend in the width direction on the front side of the boundary between the high-unit weight portion (33) and the medium-unit weight portion (35). The non-adhesive portion is an area that is not attached to underwear or the like when worn and is prone to deformation. By providing a non-adhesive portion extending in the width direction (W), an area overlapping the non-adhesive portion of the main body portion (2) is deformed, so that distortion of the main body portion (2) can be absorbed. The non-adhesive portion extending in the width direction may be an area between adhesive portions in the front-back direction in a form in which the adhesive portions extending in the width direction are arranged at intervals in the front-back direction.

The boundary between the high unit weight portion (33) and the medium unit weight portion (35), the low unit weight portion (34) extending in the width direction, and the non-adhesive portion may be provided at least in one, or they may be provided in combination. In addition, the boundary between the high unit weight portion (33) and the medium unit weight portion (35), the low unit weight portion (34) extending in the width direction, and the non-adhesive portion may reach the outer edge of the absorbent core (31), or may not reach the outer edge of the absorbent core (31).

In addition, the first compression member (81) overlaps the first low-unit-weight member (431) constituting the second-side low-unit-weight region (R41). By means of the first compression member (81), the collapse of the shape of the first low-unit-weight member (431) due to deformation can be suppressed, and deformation of the absorbent core (31) can be sustained. In addition, the region where the second-side low-unit-weight region (R41) and the first compression member (81) overlap tends to have a greater difference in rigidity with respect to the surrounding absorbent core (31), and thus tends to become a deformation starting point. Therefore, by deforming the absorbent core (31) when the package is deployed, the flap peeling sheet (76) can be peeled off from the wing adhesive member (72) more smoothly.

Likewise, the second compression member (82) overlaps the second low-unit-weight member (432) that constitutes the second-side low-unit-weight region (R41) and the intermediate low-unit-weight region (R44). By means of the second compression member (82), the shape collapse of the second low-unit-weight member (432) due to deformation can be suppressed, and deformation of the absorbent core (31) can be sustained. In addition, the region where the intermediate low-unit-weight region (R44) and the second compression member (82) overlap tends to have a rigidity difference with respect to the surrounding absorbent core (31), and thus tends to become a deformation starting point even more easily. Therefore, by deforming the absorbent core (31) when the package is deployed, the flap peeling sheet (76) can be peeled off from the wing adhesive member (72) even more smoothly.

Likewise, the third compression member (83) overlaps the third low-unit weight member (433) constituting the intermediate low-unit weight region (R44). By the third compression member (83), the collapse of the shape of the third low-unit weight member (433) due to deformation can be suppressed, and deformation of the absorbent core (31) can be sustained. In addition, the region where the intermediate low-unit weight region (R44) and the third compression member (83) overlap is likely to have a difference in rigidity with respect to the surrounding absorbent core (31), and is more likely to become a deformation starting point. Therefore, by deforming the absorbent core (31) when the package is deployed, the flap peeling sheet (76) can be peeled off from the wing adhesive member (72) more smoothly.
