Description

Absorbent article

Technical Field

The present invention relates to an absorbent article such as a sanitary napkin.

Background

Patent document 1 discloses a sanitary napkin including a front sheet, a back sheet, and an absorbent body. The absorber is disposed between the front sheet and the back sheet. The absorbent body includes a high basis weight portion having a relatively high basis weight and a low basis weight portion adjacent to the high basis weight portion and having a relatively low basis weight. The low-basis weight portions are formed in a plurality of linear shapes along the longitudinal direction and the width direction of the sanitary napkin. The high basis weight portion corresponds to a portion formed by dividing the low basis weight portion into straight lines. Each of the plurality of high basis weight portions is rectangular in plan view except for the high basis weight portion located at the edge of the absorbent body. The high basis weight portions of the absorbent body have the same shape and the same size as each other except for the high basis weight portions located at the edges of the absorbent body.

Disclosure of Invention

The inventors of the present application have found the following problems with respect to the absorbent article including the absorbent body as described in patent document 1. The wearer's body has various shapes (curvatures) corresponding to the parts thereof. Thus, there are cases where: if the size of the high basis weight portion of the absorbent body is constant, even if the absorbent article is appropriately attached to a certain portion of the wearer, the absorbent article is difficult to attach to another portion of the wearer.

In addition, the following is also considered: by making the high basis weight portion of the absorbent body small in size, the absorbent body can be easily fitted to the body of the wearer. However, if the size of the high basis weight portion is made too small, the entire absorbent article is too easily bent. This causes a problem that the absorbent article is twisted and gives a wearer a sense of discomfort.

In addition, the absorbent article needs to be fitted along the wearer's hips for the wearer to feel comfortable. In particular, for the comfort of the wearer, it is preferable that the rear portion of the absorbent article be curved in a gentle arc such that the rear portion entirely wraps the buttocks. Therefore, it is not preferable to form the high basis weight portion of the absorbent body to be too small in the rear portion of the absorbent article. In addition, in the rear portion of the absorbent article which is strongly pressed against the buttocks in the sleeping position, it is not preferable to form the high-basis-weight portion of the absorbent body to be too small in size from the viewpoint of durability.

Accordingly, it is desirable to provide an absorbent article that can be more easily fitted to each part of a wearer and can reduce discomfort given to the wearer.

An absorbent article in one form includes: an absorbent article comprising a front-back direction and a width direction orthogonal to each other, an excretory opening contact region facing an excretory opening of a wearer, a rear region located on the rear side of the excretory opening contact region and having hip flaps bulging in the width direction, an absorbent body disposed at least in a region from the excretory opening contact region to the rear region, and a plurality of grooves dividing the absorbent body into a plurality of zones at least in a region from the excretory opening contact region to the rear region, wherein the absorbent article comprises: a 1 st position which is located on the rear side of the excretory opening contact region, on the front side of the maximum width position of the hip flap, and which is the narrowest in width in the width direction of the absorbent article; and a 2 nd position corresponding to a maximum width position of the hip flaps, a length of the section in the front-back direction at the 1 st position being smaller than a length of the section in the front-back direction at the 2 nd position, a central groove being one of the plurality of grooves being provided in the rear region along a center line connecting centers in the width direction of the absorbent article.

In addition, there are also portions having different dimensional relationships and ratios from each other in the drawings.

(1) Integral structure of absorbent article

Fig. 1 is a plan view of an absorbent article according to an embodiment. Fig. 2 is a plan view of the absorbent article viewed from the side opposite to the viewing direction of fig. 1. Fig. 5 is a schematic view of the absorbent article in a use state in a standing position. Fig. 6 is a schematic view of the absorbent article in a virtual state in which the hip of the wearer is not deformed by compression in the sleeping position. Fig. 7 is a schematic view of the absorbent article in a state in which the buttocks of the wearer are crushed and deformed in the sleeping position. Fig. 8 is a schematic cross-sectional view of the absorbent article in a use state, taken along line 6A-6A of fig. 1.

The absorbent article 1 has a front-back direction L, a width direction W, and a thickness direction T. The front-back direction L is a direction extending from the front side (abdomen side) of the wearer to the back side (back side) of the wearer, or a direction extending from the back side of the wearer to the front side of the wearer. The width direction W is a direction orthogonal to the front-rear direction L. The "skin surface side" corresponds to a side facing the skin of the wearer when used. The "non-skin surface side" corresponds to a side opposite to the skin surface side in use, that is, a side facing in a direction opposite to the skin of the wearer.

The absorbent article 1 includes a excretory opening abutment region S1, a front region S2, a rear region S3, and an intermediate region S4. The excretory opening abutment region S1 is a region opposing the excretory opening (e.g., vaginal opening) of the wearer. When the absorbent article is worn on underwear, the excretory opening contact region S1 is located in the crotch portion of the underwear. That is, the excretory opening contact region S1 is a region disposed at the crotch of the wearer, i.e., between the legs of the wearer.

The front region S2 is located on the front side of the drain port contact region S1. The front end edge of the front side region S2 defines the front end edge 91 of the absorbent article 1. The rear region S3 is located rearward of the drain contact region S1 and the intermediate region S4. The rear end edge of the rear region S3 defines the rear end edge 92 of the absorbent article 1. The length in the front-rear direction L of the rear region S3 is preferably longer than the length in the front-rear direction L of the excretory opening abutment region S1.

The intermediate region S4 is a region between the excretory opening abutment region S1 and the rear region S3. The length of the intermediate region S4 in the front-rear direction L is preferably 10mm to 50 mm.

The rear region S3 includes a 1 st rear region S3a located more frontward than the center of the rear region S3 in the front-rear direction L and a 2 nd rear region S3b located more rearward than the center of the rear region S3 in the front-rear direction L.

Here, as shown in fig. 5, the intermediate region S4 is located slightly rearward of the crotch of the wearer. The intermediate region S4 corresponds to a region of the wearer' S body where the curvature is high. In this way, the region of the wearer' S body with a high curvature corresponds to a region having a length of 10mm to 50mm on the rear side of the excretory opening contact region S1.

The 1 st posterior region S3a is opposite the portion of the body having a lower curvature than the portion of the body at the middle region S4. In addition, the 2 nd posterior region S3b is opposed to a part of the body having a curvature lower than that of the part of the body at the 1 st posterior region S3 a.

The flap 3 is preferably provided in the drain port abutting region S1. The wing sections 3 are folded back toward the non-skin surface side of the crotch section of the undergarment during use. In addition, in the rear side region S3, it is preferable to provide the hip flaps 4 bulging outward in the width direction W. The flap portions 3 extend to the outer side in the width direction W than the outer edge of the absorbent core described later in the excretory opening contact region S1. The hip flap 4 is provided in the rear region S3, and the hip flap 4 is a portion that bulges in the width direction W. In the present embodiment, the hip flaps 4 extend to the outer side in the width direction W than the outer edge of the absorbent core described later in the excretory opening contact region S1. Instead of this, an absorbent body may be provided to the hip flaps 4.

The leading edge of the wing portion 3, which corresponds to the portion located on the front side of the two portions recessed to the maximum extent inward in the width direction W, is defined by the root portion of the wing portion 3. The boundary between the excretory opening contact region S1 and the front region S2 may be defined by the front edge of the flap portion 3. The rear end edge of the wing portion 3, which corresponds to the portion located on the rear side of the two portions recessed to the maximum extent inward in the width direction W, is defined by the root portion of the wing portion 3. Here, a region in the front-rear direction L between the front end edge of the wing portion 3 and the rear end edge of the wing portion 3 is referred to as a "wing portion region". In the absorbent article having the wing portions, the excretory opening contact region S1 is substantially the same region as the wing portion region. Thus, it should be noted that the term "drain port abutment region S1" and "wing region" in the present specification can be replaced with each other.

Hereinafter, the position that is rearward of the excretory opening contact region S1, forward of the maximum width position P2 of the hip flaps 4, and narrowest in the width direction W of the absorbent article 1 is referred to as "position 1P 1". In the absorbent article having the wing sections, the 1 st position P1 corresponds to the rear end edge of the wing section 3 described above. Hereinafter, the position corresponding to the maximum width position of the hip flaps will be referred to as "position 2P 2". In addition, an intermediate position between the 1 st position P1 and the 2 nd position is referred to as "3 rd position P3".

The absorbent article 1 has an absorbent body 30. The absorber 30 is provided at least in the excretory opening contact region S1, the intermediate region S4, and the rear region S3. The absorbent body 30 may also extend from the excretory opening abutment region S1 to the front side region S2. The absorber 30 is sandwiched between the liquid-permeable skin-facing sheet 10 and the liquid-impermeable non-skin-facing sheet 20. The absorbent body 30 may also include an absorbent core containing an absorbent material for absorbing liquid and a core-covering layer covering the absorbent core. The absorbent material constituting the absorbent core can be formed of, for example, hydrophilic fibers, pulp, and Super Absorbent Polymers (SAP).

The flesh facing sheet 10 preferably includes a front sheet 11 and side sheets 12. The topsheet 11 covers the absorbent body 30. The side sheet 12 extends outward in the width direction W from an end in the width direction W of the front sheet 11. The inner side edge 12E of the side panel 12 extends in the front-rear direction L and is folded back outward in the width direction W. Between the folded side pieces 12, a stretchable member 90 stretchable in the front-rear direction L is disposed. The inner edge 12E of the side sheet 12 is not joined to the front sheet 11. The stretchable member 90 is joined to the side sheet 12 in an extended state to a predetermined length. Thereby, the inner side edge 12E of the side panel 12 contracts in the front-rear direction L in a natural state. Thus, the inner edge 12E of the side panel 12 and the stretchable member 90 constitute a standing leak-proof cuff.

The joint between the stretchable member 90 and the side sheet 12 is a portion that exhibits the stretching force of the stretchable member 90. The stretchable member 90 has non-joined portions at both ends in the front-rear direction L that are not joined to the side sheets 12. The non-joined portion of the stretchable member 90 becomes a portion in which the stretching force of the stretchable member 90 cannot be exhibited. In the present specification, the portion of the stretchable member 90 excluding the portion that does not exhibit the stretching force of the stretchable member 90 is referred to as an "effective length portion" of the stretchable member 90.

Preferably, the effective length portion of the stretchable member 90 is disposed forward of the maximum width position P2 of the hip flap 4. This can suppress contraction of the regions near the maximum width position P2 and on the rear side of the position P2 of the hip flaps 4 in the front-rear direction L. As a result, the rear region S3 can be deformed to widely wrap the buttocks of the wearer.

(2) Detailed structure of absorbent

The absorber 30 has a plurality of grooves 42 that divide the absorber 30 into a plurality of segments (high basis weight portions) 40 at least in the intermediate region S4 and the rear region S3. In the present embodiment, a plurality of grooves 42 that divide the absorber 30 into a plurality of segments 40 are formed only in the intermediate region S4 and the rear region S3. Instead, a plurality of grooves 42 that divide the absorber 30 into a plurality of divisions 40 may be provided in the excretory opening contact region S1 and the front region S2.

The portion partitioned by the plurality of grooves 42 constitutes a high basis weight portion 40 having a basis weight larger than the basis weight of the grooves 42. The weight per unit area of the grooves 42 is smaller than the weight per unit area of the high weight portion 40. The groove 42 may be formed by a recess having a thickness smaller than the thickness of the weight unit area 40. In addition, the groove 42 may be a portion where no absorbent material is present. In this case, the grooves 42 are regions where the basis weight of the absorbent material is substantially zero, and the grooves 42 are configured as through grooves.

The weight per unit area of the absorbent material at the portion of the channel 42 is preferably 150g/m²Hereinafter, more preferably 100g/m²The following. Further, it is more preferable that the weight per unit area of the absorbent in the grooves 42 is substantially 0g/m². The weight per unit area of the absorbent in the grooves 42 is preferably that of the absorbent in the high weight-per-unit area portion 40The weight per unit area is 60% or less, more preferably 50% or less.

In the present embodiment, the high basis weight portions 40 formed by dividing the grooves 42 are provided in the intermediate region S4 and the rear region S3. The high basis weight portions 40 other than the high basis weight portions 40 arranged at the edges of the absorber 30 are divided into rectangles or squares. From the viewpoint of easily following the movement of the body, it is preferable that the high basis weight portions 40 other than the high basis weight portions 40 existing at the edge of the absorber 30 have substantially the same shape in the same regions S1, S2, S3, and S4. Instead, the high basis weight portion 40 may have a shape other than a rectangle or a square.

Preferably, the groove 42 is formed linearly along the front-rear direction L and the width direction W. Instead, the groove 42 may have a curved or bent shape.

In addition to the embodiment shown in fig. 1, the high basis weight portions 40 having different shapes or sizes may be present in the same regions S3 and S4. In this case, the groove 42 may not be formed linearly along the front-rear direction L and the width direction W. The grooves 42 serve as boundaries for changes in the rigidity of the absorber 30. Therefore, the grooves 42 easily serve as the base points of deformation of the absorber 30. Preferably, the groove 42 extending in the width direction W extends from one end of the absorbent body 30 to the other end of the absorbent body 30 at least in the intermediate region S4.

In the absorbent article of the present embodiment, the length in the front-rear direction L of the high basis weight portion 40 at the 1 st position P1 is smaller than the length in the front-rear direction L of the high basis weight portion 40 at the 2 nd position P2. Here, in the present specification, in the case where there is no high unit area weight portion 40 at the 1 st position P1 or the 2 nd position P2, that is, in the case where the 1 st position P1 or the 2 nd position P2 is located in the groove 42, "the high unit area weight portion 40 at the 1 st position P1" and "the high unit area weight portion 40 at the 2 nd position P2" are interpreted as "the high unit area weight portion 40 adjacent to the 1 st position P1" and "the high unit area weight portion 40 adjacent to the 2 nd position P2", respectively. In addition, when the lengths of the plurality of high unit area weight portions 40 at the 1 st position P1 are different from each other and the lengths of the plurality of high unit area weight portions 40 at the 2 nd position P2 are different from each other, the "length of the high unit area weight portions 40 in the front-rear direction L" means "the maximum value among the lengths of the plurality of high unit area weight portions 40 in the front-rear direction L".

According to the above configuration, the length of the high basis weight portion 40 in the front-rear direction L is substantially smaller in the middle region S4 than in the rear region S3. Thereby, the absorber 30 is easily deformed in the front-rear direction L in the intermediate region S4. To further exhibit this effect, it is preferable that the length in the front-rear direction L of all the high basis weight parts 40 at the 1 st position P1 be smaller than the length in the front-rear direction L of all the high basis weight parts 40 at the 2 nd position P2.

The middle region S4 including the 1 st position P1 is a portion where force from the legs of the wearer is easily applied. Since the intermediate region S4 is easily deformed in the front-rear direction L, the absorbent body 30 in the intermediate region S4 can be deformed to follow the movement of the wearer. This allows the absorbent article 1 to be maintained in a state of being fitted to the body in the vicinity of the excretory opening of the wearer even during the movement of the wearer.

Here, the length of the intermediate region S4 in the front-rear direction L is set to 10mm to 50mm, and thus, particularly in a portion where the curvature of the wearer' S body is high, the intermediate region S4 of the absorbent body 30 can be easily attached to the portion.

In the rear region S3, the length of the high basis weight portion 40 in the front-rear direction L is substantially increased. This can suppress the entire rear region S3 from being easily bent, and can prevent the rear region S3 from being twisted. As a result, the uncomfortable feeling given to the wearer can be reduced. Further, since the rear region S3 is a region facing the buttocks of the wearer having a small curvature, the rear region S3 can be made to sufficiently fit the buttocks of the wearer even if the high basis weight portion 40 has a large size (see also fig. 5).

In particular, in the sanitary napkin for night use in which the length in the front-rear direction L of the rear region S3 is greater than the length in the front-rear direction L of the front region S2, the rear region S3 is strongly deformed by the buttocks of the wearer in the sleeping position, and therefore, the absorbent body 30 is likely to be twisted. In particular, it is preferable to suppress twisting of the absorbent body in the back region S3 by making the length of the back region S3 in the front-back direction L longer.

Further, since the length of the intermediate region that is relatively easily deformed in the front-rear direction L is 10mm or more, the deformation of the excretory opening contact region S1 is less likely to be transmitted to the rear region S3. Thereby, the excretory opening abutment region S1 and the rear region S3 are easily deformed into different shapes, respectively. Thus, the regions S1, S2, and S3 of the absorber 30 are easily fitted to the shape of the wearer' S body.

The center groove 42a, which is one of the plurality of grooves 42, is provided along a center line CL formed by connecting the centers in the width direction W of the absorbent article in the rear side region S3. Thereby, the center of the rear region S3 in the width direction W is deformed into a convex shape by being forced from the outside in the width direction W to the inside in the width direction W (see fig. 8). The center in the width direction W of the rear region S3 is opposite to the hip cleft of the wearer. Thus, the rear side region S3 is easily fitted in match with the wearer' S gluteal cleft.

In the rear side region S3, the length of the center groove 42a in the front-rear direction L is preferably 120mm or more, and more preferably 150mm or more. In a cross section of the wearer's body along the front-rear direction L, a cleft between buttocks (cleft buttocks) exists in a region from the rear of the perineum to the coccyx. By extending the center groove 42a in the rear side region S3 long as described above, the rear side region S3 can protrude toward the hip cleft of the wearer in the region from the rear of the perineum to the coccyx in the use state of the absorbent article.

The length in the front-rear direction L of the high unit area weight portion 40 at the 1 st position P1 is smaller than the length in the front-rear direction L of the high unit area weight portion 40 at the 3 rd position P3. In addition, the length in the front-rear direction L of the high unit area weight portion 40 in the 3 rd position P3 is smaller than the length in the front-rear direction L of the high unit area weight portion 40 in the 2 nd position P2. In the present specification, in the case where there is no high unit area weight part 40 at the 3 rd position P3, that is, in the case where the 3 rd position P3 is located at the groove 42, "the high unit area weight part 40 at the 3 rd position P3" is interpreted as "the high unit area weight part 40 adjacent to the 3 rd position P3". In addition, in the case where the lengths of the plurality of high basis weight portions 40 at the 3 rd position P3 are different from each other, "the length of the high basis weight portions 40 in the front-rear direction L" means "the maximum value among the lengths of the plurality of high basis weight portions 40 in the front-rear direction L". According to this structure, the high basis weight portion 40 has a large size in the 2 nd rear region S3b facing the portion of the wearer' S buttocks near the back. Therefore, the absorbent article 1 can be suppressed from being twisted at the portion of the buttocks of the wearer close to the back, and the wearer can be given a feeling of reassurance.

Preferably, the area of the high unit area weight part 40 at the 1 st position P1 is smaller than the area of the high unit area weight part 40 at the 2 nd position P2. In the present specification, in the case where there is no high unit area weight portion 40 at the 1 st position P1 or the 2 nd position P2, that is, in the case where the 1 st position P1 or the 2 nd position P2 is located in the groove 42, "the area of the high unit area weight portion 40 at the 1 st position P1" and "the area of the high unit area weight portion 40 at the 2 nd position P2" are respectively interpreted as "the area of the high unit area weight portion 40 adjacent to the 1 st position P1" and "the area of the high unit area weight portion 40 adjacent to the 2 nd position P2". In addition, when the lengths of the plurality of high basis weight portions 40 at the 1 st position P1 are different from each other, or the lengths of the plurality of high basis weight portions 40 at the 2 nd position P2 are different from each other, "the area of the high basis weight portion 40 at the 1 st position P1" and "the area of the high basis weight portion 40 at the 2 nd position P2" mean "the maximum value among the areas of the high basis weight portions 40 at the 1 st position P1" and "the maximum value among the areas of the high basis weight portions 40 at the 2 nd position P2", respectively. Thus, in general, the size of the high unit area weight portion 40 in the middle region S4 is smaller than the area of the high unit area weight portion 40 in the rear region S3. Therefore, the absorbent body 30 can be more easily deformed in the front-back direction L and the width direction W in the intermediate region S4, and the absorbent body 30 in the intermediate region S4 can be more easily deformed to follow the movement of the wearer.

The high basis weight portions 40 of the absorber 30 may all have the same thickness or may have different thicknesses from each other. In the excretory opening contact region S1, the thickness of the absorbent body present in the region sandwiched between the pair of front compressing sections 81 described later may be greater than the thickness of the high basis weight sections 40 in the intermediate region S4 and the rear region S3. Since the excretory opening contact region S1 is a region facing the excretory opening of the wearer, the thickness of the absorbent body in the excretory opening contact region S1 can be increased, thereby facilitating the attachment of the absorbent body to the excretory opening of the wearer.

The thick portion of the absorbent body as described above is hereinafter referred to as a "convex portion". When the convex portion exists in the region sandwiched between the pair of front compression portions 81, the groove 42 may not be formed in the convex portion. This makes it possible to bring the excretory opening contact region S1 into close contact with the skin of the wearer.

In the present specification, the length of the high basis weight portion 40 is measured with a gauge in a state where the absorbent article 1 is stretched until wrinkles of the absorbent article 1 disappear.

Fig. 6 shows a state where the cross-sectional view shown in fig. 5 is rotated by 90 degrees, that is, a state where the wearer is bedded with the back facing upward. Although the body of the wearer is pressed by the bedding in a state where the wearer is bedded upside down, fig. 6 shows a virtual state where the body of the wearer is not pressed by the bedding for convenience of explanation. Fig. 6 illustrates a virtual line LB representing bedding. The region where the virtual line LB of the bedding overlaps the body is a region where the body is pressed by the bedding and the body is deformed in a bedded state. Fig. 7 shows a state in which the body of the wearer lying on his back is pressed by the bedding and deformed. In the state shown in fig. 7, the region where the virtual lines of the body and the bedding overlap in fig. 6 is deformed. More specifically, the swelling of the buttocks of the wearer is crushed and deformed, and a part of the buttocks of the wearer is flat. The crushed and deformed portion of the hip moves toward the crotch side (left direction in fig. 7) and swells from the base of the leg toward the foot. The intermediate region S4 is disposed in the squashed portion of the buttocks. Since the high basis weight portions 40 of the intermediate region S4 are formed to be small as described above, the intermediate region S4 can be flexibly deformed along the portions of the buttocks which bulge and are crushed, and can be arranged along the portions of the buttocks which are crushed and deformed. This allows the absorbent article 1 to be fitted to the body even in a sleeping position, and prevents a gap from being formed between the absorbent article 1 and the buttocks of the wearer. As a result, discomfort to the wearer can be reduced.

(3) Compression part

The absorbent article 1 has a compressed portion formed by compressing at least the absorber 30 in the thickness direction T. The compression section preferably includes a front compression section 81 and a pair of long compression sections 82 (see fig. 1). The front compressing unit 81 and the long compressing unit 82 may be formed by compressing the skin-care sheet 10 and the absorbent core 30 in the thickness direction T.

The front compression unit 81 is provided at least in the drain port contact region S1 and extends in the front-rear direction L. The front compression section 81 may also extend from the drain port abutment region S1 to the front region S2. The front compression section 81 is bent in the width direction W near the front end edge of the absorbent body 30 and is continuously connected in a U-shape. Instead, the front-side compressing units 81 may be provided on both sides independently of each other with a center line CL formed by connecting the centers in the width direction of the absorbent article therebetween. That is, the pair of front-side compression units 81 may be provided independently in a disconnected state.

The pair of front compressing sections 81 preferably have a narrowed portion 81a narrowed inward in the width direction W in the front region S2. The narrowed portion 81a may have a shape that is narrowed more inward than the configuration shown in fig. 1. Thus, even after the excretory opening contact region S1 is deformed in a convex manner toward the excretory opening of the wearer, the front region S2 can be maintained in a relatively flat shape. This makes it possible to make the absorbent article 1 fit to the body of the wearer easily even in the region on the front side of the excretory opening of the wearer.

When a wearer wears underwear to which an absorbent article such as a sanitary napkin is attached, the excretory opening contact region S1 receives a force from both legs of the wearer that compresses the absorbent article in the width direction W. This force is applied to the front compression unit 81 provided in the drain port contact region S1. The front side compression portion 81 has a rigidity larger than that of an uncompressed portion of the absorber 30. Therefore, the front compression unit 81, which receives a force directed from the outside in the width direction W toward the inside in the width direction, compresses the absorbent body 30 in the central portion of the excretory opening contact region S1 in the width direction. Thereby, the absorbent body 30 in the central portion of the excretory opening contact region S1 deforms convexly so as to be in close contact with the body of the wearer.

The long compressed portion 82 extends in the front-rear direction L. The long compressed portion 82 may extend linearly along the front-rear direction L or may extend curvilinearly so as to be inclined with respect to the front-rear direction L. The elongated compressed portion 82 preferably extends from the 1 st rear region S3a to the 2 nd rear region S3 b.

The pair of long compressed parts 82 are provided on both sides of the rear region S3 with the center line CL therebetween, more specifically, with the center groove 42a therebetween. Since the pair of long compressed portions 82 has high rigidity, they serve as base points of deformation of the absorbent body 30. The central groove 42a sandwiched between the pair of elongated compressed parts 82 is more likely to protrude toward the body side of the wearer. This enables the rear region S3 of the absorbent article to be further fitted to match the hip cleft of the wearer (see fig. 8).

The front side compression unit 81 and the sliver compression unit 82 are disconnected from each other at the high basis weight unit 40 at the 1 st position P1, and preferably, the front side compression unit 81 and the sliver compression unit 82 are disconnected from each other at the intermediate region S4. Since the front compression unit 81 and the sliver compression unit 82 are disconnected from each other at the intermediate region S4, the force applied to the front compression unit 81 can be suppressed from being transmitted to the rear region S3 via the compression units. Thereby, the excretory opening abutment region S1 and the rear region S3 can be easily deformed independently of each other. Further, since the front compression section 81 and the long compression section 82 having high rigidity are disconnected from each other in the intermediate region S4, the absorbent body 30 can be deformed relatively freely in the intermediate region S4. Thereby, the excretory opening abutment region S1 and the rear region S3 can be more easily deformed independently of each other.

The absorbent article 1 preferably has a pressure-bonded part 51 formed by compressing the absorber 30 along the groove 42. The pressure contact portion 51 can be formed by embossing. Preferably, the pressure-bonded sections 51 are formed only in the absorber 30, and not in the skin sheet 10. Specifically, when the groove 42 is a through groove, the pressure-bonding section 51 is preferably formed in a core wrap covering the absorbent core made of an absorbent material. In the case where the groove 42 is not a through groove, the pressure-bonding section 51 is preferably formed on a core cladding layer covering the absorbent core made of an absorbent material and the absorbent material. Since the pressure-bonding sections 51 are not formed on the skin surface sheet 10, the skin feel of the skin surface sheet 10 that touches the skin of the wearer can be improved.

The pressure-bonding section 51 is preferably provided at least in the groove 42 extending in the width direction W adjacent to the high basis weight section 40 at the 1 st position P1. Preferably, the crimping portion 51 is provided along the width direction W in the intermediate area S4. The crimp 51 may also be provided on the slot 42 in the drain contact area S1, the front area S2, and the rear area S3. The pressure-bonding section 51 may be provided in the groove 42 extending in the front-rear direction L.

The pressure-bonding section 51 can suppress the shape of the absorbent material in the high basis weight section 40 from being deformed. This can maintain the shape of the high basis weight portion 40 for a long period of time.

(4) Adhesive area

As shown in fig. 2, the absorbent article 1 includes a 1 st main body adhesive region 61, a 2 nd main body adhesive region 62, a flap adhesive region 63, and a hip flap adhesive region 64 provided with an adhesive for fixing the absorbent article 1 to underwear S. These adhesive regions 61 to 64 are provided on the non-skin surface side of the non-skin surface sheet 20 provided at a position closer to the non-skin surface side than the absorber 30. The adhesive regions 61 to 64 may be covered with a release sheet before use. The release sheet can prevent the adhesive in the adhesive regions 61 to 64 from being deteriorated before use. The release sheet is removed by the wearer at the time of use.

The 1 st body bonding region 61 is disposed forward of the 2 nd body bonding region 62. The 1 st and 2 nd

body bonding regions

61 and 62 extend in the front-rear direction L. The 1 st body bonding region 61 is preferably disposed across the drain port contact region S1 and the front region S2. The 2 nd main body bonding region 62 is disposed in the rear region S3. The 2 nd main body attachment region 62 is preferably disposed across the 1 st rear region S3a and the 2 nd rear region S3 b.

The 1 st and 2 nd

body bonding regions

61 and 62 are provided in the drain contact region S1 and the rear region S3 so as to avoid the high area-basis-weight portion 40 at the 1 st position P1, and in particular so as to avoid the intermediate region S4. Specifically, it is preferable that the adhesive regions 61 to 64 are not provided in the intermediate region S4. Since the intermediate region S4 is not directly fixed to underwear by the adhesive regions 61 to 64, the absorbent article can be deformed relatively freely in the intermediate region S4. This allows the excretory opening contact region S1 and the rear region S3 to be deformed into different shapes in accordance with the shape of the body of the wearer (see also fig. 5).

In addition, the 1 st and 2 nd

body bonding regions

61 and 62 are not present at the central groove 42 a. Thereby, the rear region S3 is easily deformed to be convex at the center groove 42 a. In particular, the rear side region S3 is easily deformed into a convex shape at the center groove 42a by receiving a force from the inner side in the width direction to the outer side in the width direction from the undergarment through the

adhesive regions

61, 62. This enables the rear region S3 of the absorbent article to be further fitted in conformity with the hip cleft of the wearer.

The wing part bonding region 63 is provided in the wing part 3. The hip flap adhesive area 64 is provided in the hip flap 4. Preferably, the pair of elongated compressed parts 82 are provided in a region overlapping the 2 nd main body bonding region 62. This facilitates transmission of force from the undergarment to the pair of long compressed parts 82 via the 2 nd main body adhesive region 62. This makes it easier for the pair of long compressed parts 82 to compress the absorbent body 30 in the width direction W, and the absorbent body 30 is more likely to deform in a convex shape in the central groove 42 a.

(5) Folding of absorbent articles

The absorbent article 1 may also be individually packaged in a folded-up state. The folding of the absorbent article 1 will be described below with reference to fig. 1 to 4. Fig. 3 is a plan view of the absorbent article 1 folded along the folding line FL of fig. 1 and 2. Fig. 4 is a schematic side view of the absorbent article 1 folded along the folding line F1-folding line F3 of fig. 3.

The absorbent article 1 preferably includes a front-rear folding line FL extending in the front-rear direction L and a 1 st folding line F1, a 2 nd folding line F2, and a 3 rd folding line F3 extending in the width direction W. These folding lines FL, F1, F2, F3 are imaginary lines for folding the absorbent article 1. The front-rear folding line FL is preferably provided at a position outside the outer end of the absorbent body 30 in the width direction W.

The 1 st fold line F1 is located at the rearmost position among the plurality of fold lines F1, F2, F3 extending in the width direction W. Preferably, the 1 st fold line F1 passes over the absorbent body groove 42 in the rear side region S3. More preferably, the 1 st folding line F1 does not pass through the high basis weight portion 40 of the absorbent body. The 1 st folding line F1 enables the absorbent article 1 to be habitually folded. Thus, the absorbent article 1 is easily deformed along the 1 st folding line F1. The 1 st fold line F1 tends to deform the rear region S3 along the arc in the front-rear direction of the wearer' S buttocks. Therefore, the rear region S3 is easily fitted along the curvature of the buttocks of the wearer.

Preferably, the 1 st fold line F1 does not pass through the hip flap bond area 64. This can prevent the hip flap adhesion region 64 from being bent habitually. If the hip flap adhesive region 64 is bent habitually, the hip flap adhesive region 64 adhered to the undergarment is likely to peel off due to the influence of the habitual bending. In contrast, by avoiding the 1 st fold line F1 from passing through the hip flap adhesive region 64, the hip flaps 4 can be stably secured to the undergarment.

The 2 nd folding line F2 is provided between the 1 st folding line F1 and the 3 rd folding line F3 in the front-rear direction L. The 2 nd folding line F2 may be disposed on the front side of the pair of elongated compressed parts 82 with respect to the 2 nd folding line F2. The 2 nd fold line F2 may also pass over the 2 nd body bond region 62.

In the example shown in fig. 1, the 2 nd folding line F2 is provided at a position away from the groove 42 extending in the width direction W. Instead, the 2 nd folding line F2 may be provided on the groove 42 extending in the width direction W. In this case, there is an advantage that the absorbent article 1 is easily folded at the position of the 2 nd folding line F2. Further, since the position of the groove 42 of the absorbent body 30 is also a position that is likely to be a folding base point in the use state of the absorbent article, even if habitual bending occurs in the groove 42 due to the 2 nd folding line F2, the fit of the absorbent article is not degraded.

The 3 rd folding line F3 is provided at a position more to the front side than the 2 nd folding line F2. The 3 rd fold line F3 is preferably provided in the front side region S2. By providing the 3 rd folding line F3 at a position forward of the wing portion 3, it is possible to prevent the wing portion 3 from being bent habitually.

First, the absorbent article 1 is folded inward with the front and rear folding lines FL as a base point so that the non-skin surface side is exposed outward (see fig. 3). Preferably, the absorbent article 1 is folded in the order of the 1 st folding line F1, the 2 nd folding line F2, and the 3 rd folding line F3 from the state shown in fig. 3 (refer to fig. 4).

In the state where the absorbent article 1 is folded, the rear end edge 92 of the absorbent article is positioned inside the absorbent article. In the state where the absorbent article 1 is folded, the front end edge 91 of the absorbent article is positioned outside the absorbent article. In addition, the 1 st folding line F1 is located inside the folded absorbent article 1. The 2 nd folding line F2 and the 3 rd folding line F3 are located on the outer side of the folded absorbent article 1.

When the absorbent article 1 is folded as described above, the curvature of the absorbent article 1 is maximized at the 1 st folding line F1. Since the position of the 1 st fold line F1 having the highest curvature passes over the groove 42, the absorbent article 1 can be folded neatly. On the other hand, the curvature of the absorbent article 1 is smaller at the 2 nd folding line F2 and the 3 rd folding line F3. Therefore, even if the 2 nd folding line F2 and the 3 rd folding line F3 do not pass through the groove 42, the absorbent article 1 can be folded neatly.

In the example shown in fig. 1, the front-rear folding line FL extending in the front-rear direction L is located on the outer side in the width direction W than the absorbent body 30. Instead, the front-rear folding lines FL may pass over the absorbent body 30. By passing the front-rear folding lines FL over the absorber 30, the absorbent article 1 can be folded more compactly.

In addition, in the case where the front and rear folding lines FL pass over the absorbent body 30, it is preferable that the front and rear folding lines FL pass over the grooves 42 extending in the front and rear direction L. This makes it possible to easily fold the absorbent article 1 at the position of the front and rear folding lines FL.

(6) Embodiment 2

Fig. 9 is a plan view of the absorbent article of embodiment 2. In embodiment 2, the same components as those in embodiment 1 are denoted by the same reference numerals. Hereinafter, description of the same structure as that of embodiment 1 may be omitted.

Like embodiment 1, the absorbent article 1 of embodiment 2 includes a plurality of high basis weight portions 40 and a plurality of grooves 42. In embodiment 2, a plurality of grooves 42 that divide the absorber 30 into a plurality of segments 40 are formed not only in the intermediate region S4 and the rear region S3 but also in the excretory opening contact region S1 and the front region S2. In embodiment 2, the length of the high basis weight portion 40 in the width direction W is greater on the outer side in the width direction than on the center in the width direction.

In the example shown in fig. 9, the absorber 30 is divided into a region R1 closest to the center line CL, a region R3 closest to the widthwise outer side, and a region R2 between the region R1 and the region R3. Here, the length in the width direction W of the high basis weight portion 40 in the region R1 closest to the center line CL is smaller than the length in the width direction W of the high basis weight portion 40 in the region R2. The length of the high basis weight portion 40 in the width direction W in the region R2 is smaller than the length of the high basis weight portion 40 in the width direction W in the region R3 located most outward in the width direction.

In embodiment 2, the high basis weight portion 40 is divided into rectangular or square regions in the regions R1, R2, and R3. The groove 42 is formed linearly along the front-rear direction L and the width direction W. Preferably, the high basis weight portions 40 other than the high basis weight portions 40 present at the edges of the absorber 30 have substantially the same shape in the same regions R1, R2, and R3. In addition to the embodiment shown in fig. 9, high basis weight portions 40 having different shapes or sizes may be present in the same regions R1, R2, and R3. In this case, it is preferable that the length in the width direction W of the plurality of high basis weight portions 40 in the region R1 closest to the center line CL be smaller than the length in the width direction W of the plurality of high basis weight portions 40 in the region R2. Further, it is preferable that the length in the width direction W of the plurality of high basis weight portions 40 in the region R2 is smaller than the length in the width direction W of the plurality of high basis weight portions 40 in the region R3 located most outward in the width direction.

As described above, the length of the high basis weight portion 40 in the width direction W increases as it approaches the center line CL. This makes it easy for the absorbent article to deform in the region near the center line CL. The region near the center line CL of the absorbent article faces a highly curved portion such as a wearer's excretory opening or hip cleft. Therefore, the absorbent article 1 can be more easily fitted to the body of the wearer by easily deforming the region near the center line CL of the absorbent article.

(7) Embodiment 3

Fig. 10 is a plan view of the absorbent article of embodiment 3. In embodiment 3, the same components as those in embodiment 1 are denoted by the same reference numerals. Hereinafter, the same configurations as those of embodiment 1 may be omitted.

The absorbent article 1 of embodiment 3 has a plurality of high basis weight portions 40 and a plurality of grooves 42, as in embodiment 1. In embodiment 3, a plurality of grooves 42 that divide the absorber 30 into a plurality of segments 40 are formed not only in the intermediate region S4 and the rear region S3 but also in the excretory opening contact region S1 and the front region S2. In embodiment 3, the length in the width direction W of the high basis weight portions 40 in the intermediate region S4 is smaller than the length in the width direction W of the high basis weight portions 40 in the rear region S3.

Preferably, the high basis weight portions 40 other than the high basis weight portions 40 existing at the edges of the absorber 30 have substantially the same shape in the same regions S1, S2, S3a, and S3 b. In addition to the embodiment shown in fig. 10, high area weight portions 40 having different shapes or sizes from each other may be present in the same regions S1, S2, S3a, S3 b. In this case, it is preferable that the length in the width direction W of the plurality of high weight portions 40 in the middle region S4 is smaller than the length in the width direction W of the plurality of high weight portions 40 in the rear region S3.

Further, it is more preferable that the length in the width direction W of the plurality of high weight portions 40 in the 1 st rear region S3a is smaller than the length in the width direction W of the plurality of high weight portions 40 in the 2 nd rear region S3 b.

In the absorbent article 1 according to embodiment 3, the intermediate region S4 is more likely to deform because the high basis weight portion 40 of the intermediate region S4 is smaller in size. This makes it possible to make the intermediate region S4 more easily fit to a portion of the wearer having a high curvature.

In addition, the high basis weight portion 40 of the rear region S3 is large in size. This can prevent the entire rear region S3 from being bent too easily, and can prevent the rear region S3 from being twisted. As a result, the uncomfortable feeling given to the wearer can be reduced. Further, since the rear region S3 is a region facing the buttocks of the wearer having a small curvature, the rear region S3 can be made to sufficiently fit the buttocks of the wearer even if the high basis weight portion 40 has a large size (see also fig. 5).

(8) Embodiment 4

Fig. 11 is a plan view of the absorbent article of embodiment 4. In embodiment 4, the same components as those in embodiment 1 are denoted by the same reference numerals. Hereinafter, description of the same structure as that of embodiment 1 may be omitted.

Like embodiment 1, the absorbent article 1 of embodiment 4 includes a plurality of high basis weight portions 40 and a plurality of grooves 42. The center groove 42a, which is one of the plurality of grooves 42, is provided along the center line CL in the rear side region S3.

In embodiment 4, the width of the center groove 42a in the width direction W widens from the rear region S3 toward the middle region S4. Thus, in the wide portion of the center groove 42a, that is, the 1 st back region S3a and the middle region S4, the vicinity of the center line CL of the absorbent body 30 is likely to protrude toward the hip cleft of the wearer. On the other hand, the narrow portion of the central groove 42a, i.e., the rear portion of the 2 nd rear region S3b, is less likely to protrude toward the wearer in the vicinity of the center line CL of the absorbent body 30, and is likely to be formed flat. The rear side portion of the 2 nd rear region S3b is opposite to a region near the sacrum on the rear back side than the hip cleft of the wearer. Thus, by forming the rear side portion of the 2 nd rear region S3b to be flat, the 2 nd rear region S3b is made to fit the wearer' S body easily.

(9) Embodiment 5

Fig. 12 is a plan view of the absorbent article of embodiment 5. Fig. 12 shows one surface of the absorbent article on the side where the bonded regions 61 to 64 are provided. In embodiment 5, the same components as those in embodiment 1 are denoted by the same reference numerals. Hereinafter, description of the same structure as that of embodiment 1 may be omitted.

Like embodiment 1, the absorbent article 1 of embodiment 5 includes a 1 st main body adhesive region 61, a 2 nd main body adhesive region 62, a flap adhesive region 63, and a hip flap adhesive region 64.

The 1 st body bonding region 61 is disposed at least in the drain port contact region S1. The 1 st body attachment region 61 may also be disposed in the front side region S2. The 2 nd main body bonding region 62 is disposed in the rear region S3. In embodiment 5, the 1 st and 2 nd

body bonding regions

61 and 62 are divided into a plurality of sections along the front-rear direction L.

This allows force to be transmitted independently from the undergarment to each high unit weight portion 40 via each of the 1 st and 2 nd body

adhesive regions

61 and 62. This allows each region of the absorbent article to be deformed in accordance with the shape of the body in accordance with the difference in the shape of the body. In order to facilitate such deformation, it is preferable that the 1 st and 2 nd

body bonding regions

61 and 62 be provided at least in the excretory opening contact region S1 and the rear region S3 in correspondence with the high basis weight portions 40 in the front-rear direction L. Further, it is preferable that the 1 st and 2 nd

body bonding regions

61 and 62 are provided between the grooves 42 extending in the width direction W adjacent to each other, and are not provided on the grooves 42 extending in the width direction W.

The 1 st and 2 nd

body bonding regions

61 and 62 are provided so as to avoid the high basis weight portion 40 at the 1 st position P1, and preferably, the 1 st and 2 nd

body bonding regions

61 and 62 are provided so as to avoid the intermediate region S4. In other words, the 1 st and 2 nd

body bonding regions

61 and 62 are preferably not provided in the intermediate region S4. In addition, the 1 st and 2 nd

body bonding regions

61 and 62 are not present in the central groove 42 a.

While the present invention has been described in detail with reference to the above embodiments, it will be apparent to those skilled in the art that the present invention is not limited to the embodiments described in the present specification. The present invention can be implemented as modifications and variations without departing from the spirit and scope of the present invention defined by the claims. Therefore, the description of the present specification is for illustrative purposes and does not have any limiting meaning to the present invention.
