The skin-side sheet 2, the non-skin-side sheet 3 and the side sheet 6 each extend from the peripheral edge of the absorbent core 4, and at the end portions of at least two sheets of the extension portions, an adhesive and heat seal The end seal portion 1E is formed by being joined to each other by a known joining means such as the above. On the skin-facing surface of the napkin 1, a leak-proof groove 7 is formed in which the skin-side sheet 2 and the absorbent core 4 are integrally recessed. The leak-proof groove 7 has an annular shape in plan view, and extends from the front part A to the rear part C via the crotch part B. The leak-proof groove 7 is formed by embossing.

  As the skin-side sheet 2, it is possible to use various types of conventionally used absorbent articles of this type without any particular limitation, assuming that the sheet is a liquid-permeable sheet that can permeate body fluid such as menstrual blood. A woven fabric, a nonwoven fabric, a porous sheet or the like made of synthetic fiber or natural fiber can be used. As the non-skin-side sheet 3, various leak-proof sheets conventionally used for this type of absorbent article can be used without particular limitation, and are liquid-impermeable (including water repellency) and moisture-permeable. Are preferably used. For example, a non-skin-side sheet 3 can be suitably used as a non-skin-side sheet 3 by stretching a film made of a synthetic resin such as polyethylene in which fine powder made of a filler such as calcium carbonate is dispersed and providing fine pores. As the side sheet 6, what can be used as the non-skin side sheet 3 can be used.

  As shown in FIG. 4, the absorbent core 4 has a vertically long shape in the longitudinal direction X, the longitudinal direction thereof coincides with the longitudinal direction X, and the width direction thereof coincides with the lateral direction Y. The absorbent core 4 extends from the front part A to the rear part C via the crotch part B. In 1st Embodiment, the absorptive core 4 consists of what hold | maintained the highly water-absorbing polymer between the fiber aggregates which consist of fiber materials, such as a pulp fiber, or the fiber of this fiber aggregate, Both surfaces of the skin facing surface and the non-skin facing surface are covered with a liquid-permeable core wrap sheet (not shown) made of paper, nonwoven fabric or the like.

  As shown in FIGS. 4 and 5, the absorbent core 4 includes a standard absorbent portion 40 and a protruding portion 41 that is thicker than the standard absorbent portion 40. In the first embodiment, the standard absorbent portion 40 is a region in which both the thickness and the basis weight are relatively small in the absorbent core 4, and the protruding portion 41 is relatively both in the thickness and the basis weight in the absorbent core 4. Is a large area, the front side and the rear side of the absorbent core 4 in the longitudinal direction X are respectively the standard absorbent part 40, and the central part of the longitudinal direction X sandwiched between the pair of front and rear standard absorbent parts 40, 40 is the projecting part 41. It is. As shown in FIG. 4, the protrusion 41 in the first embodiment extends from the front part A of the napkin 1 to the rear part C via the crotch part B and has a hexagonal shape in plan view.

In the first embodiment, as shown in FIGS. 4 and 5, the protruding portion 41 includes a maximum width portion 42 extending over the entire length in the lateral direction Y of the absorbent core 4, that is, the entire width, and the maximum width portion 42. The front side convex part 43 formed ahead of the vertical direction X and the rear side convex part 44 formed behind the maximum width part 42 in the vertical direction X are provided. The hatched portions in the figure are both convex portions 43 and 44. The absorbent core 4 is formed symmetrically with respect to a virtual vertical center line CLx that bisects the absorbent core 4 in the vertical direction X and extends in the horizontal direction Y.

  As shown in FIG. 4, the entire maximum width portion 42 is disposed in the crotch portion B, and has a quadrangular shape (rectangular shape) in plan view. A pair of side edges 420 and 420 extending in the vertical direction X of the maximum width portion 42 form both side edges of a portion (crotch portion B) where the maximum width portion 42 exists in the absorbent core 4. In this way, the protrusion 41 (maximum width portion 42) that plays an important role in the expression of various characteristics such as fit and leakage prevention properties exists over the entire width of the absorbent core 4 in the crotch B, for example, Even when the wearing position of the napkin 1 slightly deviates in the lateral direction Y from the proper position due to the movement of the wearer, the protruding portion 41 (maximum width portion 42) can still come into contact with the crotch portion of the wearer. Therefore, the napkin 1 is excellent in followability to the wearer's movement, fit, and leakage prevention.

  On the other hand, as shown in FIG. 4, the front-side convex portion 43 is disposed so as to straddle the second folding line 22 that forms the boundary between the front portion A and the crotch portion B in the longitudinal direction X, and the rear-side convex portion 44 is arranged so as to straddle the first folding line 21 forming the boundary between the rear part C and the crotch part B in the vertical direction X. The front convex portion 43 has an isosceles triangle shape in a plan view as shown in FIG. 4, and is connected to both side edges 420 and 420 of the maximum width portion 42, and has two sides having the same length in the isosceles triangle. It has a vertical end 430 that is V-shaped in plan view. Similarly, the rear-side convex portion 44 has an isosceles triangle shape, is connected to both side edges 420 and 420 of the maximum width portion 42, and has a V-shape in plan view that forms two sides having the same length in the isosceles triangle. It has a longitudinal end 440. The vertical end 430 of the front convex portion 43 and the vertical end 440 of the rear convex portion 44 are arranged so that the V-shaped top portions 431 and 441 protrude outward in the vertical direction X, respectively. .

  The maximum width portion 42 and the both convex portions 43 and 44 are integrally formed. In this specification, “integrally formed” means that a plurality of portions, for example, the front convex portion 43 and the maximum width portion 42 are integrated without using a bonding means such as an adhesive or heat fusion. Meaning that they are integrally formed from the same material. When a plurality of parts of the absorbent core 4 are integrally molded, the stool has a continuity in which excretion fluid such as menstrual blood can move smoothly.

  In 1st Embodiment, the protrusion part 41 of the absorptive core 4 protrudes from the non-skin opposing surface 40b of the standard absorption part 40 to the non-skin side sheet | seat 3 side, as shown in FIG. Thus, as shown in FIG.2 and FIG.5, since the protrusion part 41 which is a part of the absorptive core 4 protrudes in the non-skin side sheet | seat 3 side rather than the standard absorption part 40 which is the periphery part. A space 47 is formed between the non-skin facing surface 40 b of the standard absorbent portion 40 of the absorbent core 4 and the non-skin side sheet 3.

In the first embodiment, as shown in FIG. 4, a groove 45 is formed in the standard absorbing portion 40 along the longitudinal end 430 of the front convex portion 43 and the longitudinal end 440 of the rear convex portion 44. . Further, outside the groove 45 in the longitudinal direction X, a plurality of linear grooves 46 extend in the longitudinal direction X, and a plurality of linear grooves 46 also extend in the lateral direction Y, and are orthogonal to each other. Thus, the standard absorption portion 40 may be partitioned into a plurality of small regions by a plurality of linear grooves 46 having a lattice shape in plan view. In the first embodiment, the grooves 46 are formed. The groove 45 and the groove 46 are connected. In the standard absorbent portion 40, the small area is a high basis weight portion having a relatively large basis weight, and the formation portions of the grooves 45 and 46 are low basis weight portions having a relatively small basis weight. In the first embodiment, as shown in FIG. 5, the groove 45 has an opening in the non-skin facing surface 40 b of the standard absorbent portion 40, and the skin facing surface 40 a side of the standard absorbent portion 40 forms the bottom of the groove 45. doing. Although not shown, the groove 46 similarly has an opening in the non-skin facing surface 40b of the standard absorbent portion 40. On the contrary, the grooves 45 and 46 may have an opening in the skin facing surface 40a of the standard absorbent portion 40.

  The grooves 45 and 46 of the standard absorbent portion 40 are intentionally reduced in a known absorbent core manufacturing method using a fiber stacking device as compared with the peripheral portion of the core forming material including the absorbent material. Is a so-called embossed groove, that is, a recess formed by embossing (pressing) a flat plate-like absorbent core having a uniform basis weight and no irregularities on the surface. Absent. Therefore, the normal embossed groove has a higher density than the peripheral portion because the core forming material is consolidated by embossing, but the grooves 45 and 46 are not consolidated in the formation process. There is no substantial difference in density in comparison with the peripheral part (non-grooved part). In addition, the normal embossed groove has no substantial difference in basis weight in comparison with its peripheral part, but the grooves 45 and 46 have a lower basic weight than the peripheral part.

  A known method for manufacturing an absorbent core that can be used for forming the grooves 45 and 46 is, for example, an accumulation core formed on the outer surface of a fiber stacking device (rotating drum or the like) by using a core forming material supplied in an air flow. In this step, the step of depositing at the bottom of the concave portion is used. In such a step, the concave portion for accumulation having a partly different hole area ratio is used. Specifically, the step corresponds to a portion where the grooves 45 and 46 are to be formed. By using recesses for accumulation in which the opening ratio of the bottom is adjusted to be relatively low, a thin and low basis weight portion in which the grooves 45 and 46 are formed, and a meat in which no grooves (recesses) are formed. An absorbent core 4 having a thick and high basis weight portion can be formed.

  Thus, the absorptive core 4 in the first embodiment is formed by partially varying the amount of accumulated core forming material, and the portion where the amount of accumulated core forming material is relatively small is standard. A portion where the absorbent portion 40 and the core forming material have a relatively large amount of fibers is a protruding portion 41 including a maximum width portion 42, a front convex portion 43, and a rear convex portion 44. Therefore, the protruding portion 41 is formed to have a larger basis weight as well as thickness than the standard absorbing portion 40.

  The standard absorbent portion 40 in the sanitary napkin 1 is the small region surrounded by the grooves 45 and 46 that are relatively high basis weight portions, and the linear relatively low basis weight portion 45 that surrounds the small regions. , 46 and a block structure having a number of individually independent block regions. In the first embodiment, such a structure is adopted as shown in FIG. By making the standard absorbent portion 40 into a block structure, the absorbent core 4 becomes flexible in both the vertical direction X and the horizontal direction Y, and as a result, the absorbent core 4 has a shape of the wearer's body. It will be easy to follow. Furthermore, since excrement such as menstrual blood can be guided and flow through the relatively thin grooves 45 and 46, the absorbent core 4 has liquid diffusibility in the vertical direction X and the horizontal direction Y. Excellent.

  In the stacked body 10 in the unfolded state as shown in FIG. 3, the individual package 20 of the first embodiment first folds the first folding region 12 on the central region 11 along the first folding line 21, and then The two-fold region 13 is folded on the first fold region 12 at the second fold line 22, and then the extended portions from the side edges along the longitudinal direction X of the napkin 1 in the packaging material 9 are bonded to each other with an adhesive, It is manufactured by forming the sealing portion 23 (see FIG. 1A) by bonding by a known bonding means such as heat sealing and arranging the fastening tape 30 at the predetermined position.

  Here, referring again to the configuration particularly closely related to the main characteristics of the individual package 20 of the first embodiment, the protruding portion 41 of the absorbent core 4 straddles the single folding line 21 from the central region 11. Extending to the first folding region exposed portion 122 (see FIGS. 2 to 4), the rear-side convex portion 44 as the extending portion has an isosceles triangle shape in plan view as shown in FIG. The length, that is, the width in the lateral direction Y gradually decreases as the distance from the distance increases. Further, as shown in FIG. 1, the rear side convex portion 44 does not reach the boundary 91 between the first folding region exposed portion 122 and the second folding region 13, and the rear side convex portion 44 and the boundary 91 The standard absorption part 40 exists between them.

  And as one of the main features of the individual package 20 of the first embodiment, as shown in FIG. 1, when the first folding region exposed portion 122 is viewed from the top, the fastening tape 30 and the first of the protrusion 41 are used. The point which the back side convex part 44 which is the extension part to the folding area | region exposed part 122 has overlapped is mentioned. That is, the fastening tape 30 overlaps the longitudinal end 440 of the rear side convex portion 44, which is a boundary between the rear side convex portion 44 and the standard absorbing portion 40 in the first folding region exposed portion 122.

  When opening the unopened individual package 20 as shown in FIGS. 1A and 2, the free end portion 32 of the fastening tape 30 is usually picked with fingers, and this is removed from the first folding region exposed portion 122. It peels off from the upper surface, and also pulls the fastening tape 30 as it is, and performs an operation of peeling the packaging materials 9 joined by the sealing portion 23.

  However, in the individual package 20 of the first embodiment, there is a difference in thickness between the rear side convex portion 44 and the standard absorbing portion 40 at the position where the longitudinal end 440 of the rear side convex portion 44 is formed. The level | step difference resulting from this has arisen (refer FIG.2 and FIG.5). And in the individual package 20 of 1st Embodiment, since the fastening tape 30 has overlapped with the vertical direction end 440 of the back side convex part 44 as above-mentioned, ie, it has overlapped with the said level | step difference, it is the piece of an unopened state When the free end 32 of the fastening tape 30 in the body 20 is to be picked with a finger according to a conventional method, the fastening tape 30 is stopped by the pressure when the fastening tape 30 is pushed from above with the tip of the finger (for example, the index finger). The individual packaging 20 is compressed in the thickness direction around the lower part of the adhesive tape 30, and the members facing each other across the step, for example, the non-skin side sheet 3 and the standard absorbent part 40 are in close contact with each other. . As a result, in the individual package 20, as shown in FIG. 6, the thickness of the fixed end portion 31 of the fastening tape 30 and the lower portion in the vicinity thereof is smaller than the thickness of the free end portion 32 and the lower portion in the vicinity thereof. In addition, since the free end portion 32 easily floats from the upper surface of the first folding region exposed portion 122, the free end portion 32 can be easily picked up with fingers, and the portion where the thick protruding portion 41 is folded is formed. Even when the bulge rises and becomes bulky, the subsequent opening operation can be performed smoothly and quickly. In addition, the operation can be easily performed without being greatly affected by the ease of picking the free end 32 of the fastening tape 30.

  Moreover, in 1st Embodiment, the protrusion part 41 of the absorptive core 4 is extended from the center area | region 11 to the 2nd folding area | region 13 through the one folding line 22 (refer FIGS. 2-4), the extension As shown in FIG. 1, the front-side convex portion 43 that is the protruding portion does not reach the front-side longitudinal end 40 </ b> E of the standard absorbent portion 40, and the front-side convex portion 43 and the fastening tape 30 (fixed end portion 31). Is a step due to a difference in thickness between the front convex portion 43 and the standard absorbing portion 40. Therefore, in the first embodiment, in addition to the step on the rear convex portion 44 side described above, the presence of the step on the front convex portion 43 side causes the individual packaging when the fastening tape 30 is pressed from above. The degree of compression of the body 20 is relatively large, so that the free end portion 32 of the fastening tape 30 is more likely to float from the upper surface of the first folding region exposed portion 122.

  Further, in the first embodiment, as shown in FIGS. 2 and 5, the protruding portion 41 including the maximum width portion 42, the front side convex portion 43, and the rear side convex portion 44 is not in the peripheral standard absorbing portion 40. Since the space portion 47 is formed between the standard absorbent portion 40 and the non-skin side sheet 3 by protruding from the position of the skin facing surface 40b to the non-skin side sheet 3, the fastening tape 30 is The degree of compression of the individual package 20 when pressed from above is further increased, and the ease of gripping the free end 32 is further improved. From the standpoint of ensuring the effects of the formation of the space 47 more reliably, and from the viewpoint of the fit and leakage prevention of the napkin 1, the height of the space 47, that is, the protrusion of the protrusion 41P. The height H (see FIG. 5) is preferably 0.5 mm or more, more preferably 1.0 mm or more, and preferably 15 mm or less, more preferably 10 mm or less.

Moreover, in 1st Embodiment, as shown in FIG.1 (b), the 1st in the fastening tape 30 is shown.
As for the surface facing the folding region exposed portion 122, the free end portion 32 side is a non-bonding portion 33 that does not have adhesiveness to the first folding region exposed portion 122, and the remaining portion is a bonding portion 34. In the top view of the first folding region exposed portion 122 as shown in FIG. 5B, the adhesive portion 34 of the fastening tape 30 and the rear side that is the extended portion of the protruding portion 41 to the first folding region exposed portion 122. The portion (minimum width portion) having the shortest length, that is, the width in the lateral direction Y of the convex portion 44 overlaps. In the form shown in FIG. 1B, the minimum width portion is the front end portion, that is, the top portion 441 of the longitudinal end 440 of the rear side convex portion 44 and the vicinity thereof. In general, the part where the adhesive part 34 exists is a part that is easily pressed by a finger such as an index finger when trying to pick the free end 32 of the fastening tape 30 with a finger, and such a part that is easily compressed in the thickness direction. The adhesive portion 34 and the minimum width portion of the rear-side convex portion 44, that is, a portion where a step due to the thickness difference between the rear-side convex portion 44 and the standard absorbing portion 40 is overlapped with each other. The ease of picking the free end 32 of the tape 30 can be further improved.

  Moreover, in 1st Embodiment, as shown to Fig.1 (a), the fastening tape 30 is distribute | arranged to the center of the horizontal direction Y of the individual body 20, Therefore The free end part 32 of the fastening tape 30 is provided. The degree of freedom in the pulling direction when picking and pulling a finger with a finger is high and not only pulling in parallel to the vertical direction X but also pulling in the direction crossing the vertical direction X improves the opening operation of the individual package 20 Has been.

  In addition, as shown in FIG. 1, in the first embodiment, the boundary between the rear side convex portion 44 and the standard absorbing portion 40, that is, the longitudinal end 440 of the rear side convex portion 44 is stopped in the top view. Since the portion overlapping the attachment tape 30 has a V shape having a top portion 441 projecting toward the fixed end portion 31 side of the attachment tape 30, the free end portion 32 of the attachment tape 30 is grasped with fingers. As a pulling direction when pulling, in addition to being parallel to the vertical direction X, it is possible to select a direction orthogonal to each of the pair of vertical ends 440 and 440 existing on the left and right sides of the top portion 441. On the other hand, for example, in a conventional absorbent article individual body having a typical mid-high portion (projecting portion) having a quadrangular shape in plan view, the longitudinal end of the mid-high portion overlapping the fastening tape is in the lateral direction. Therefore, there is only one longitudinal direction as a pulling direction when the free end of the fastening tape is picked up with fingers and pulled. Thus, the individual package 20 of the first embodiment can cope with various opening methods in combination with the fastening tape 30 being arranged at the center in the lateral direction Y of the individual package 20. .

From the viewpoint of ensuring the above-described effects, the first folding region exposed portion 122 has a central portion in the lateral direction Y on the first folding line 21 side (more specifically, a rear convex portion. 44 is the highest rigidity, and the rigidity of both end portions in the lateral direction Y on the first folding line 21 side (more specifically, the non-arrangement part of the rear convex portion 44 on the first folding line 21 side) is high. It is preferable that other parts other than both parts have intermediate rigidity between both parts. Here, “the portion on the first folding line 21 side in the first folding region exposed portion 122” refers to the first folding region exposed portion 122 and the first folding region 21 in the unopened individual package 20. It means an area within 5 mm on the boundary 91 side with the second folding area. Since such a magnitude relationship is established with respect to the rigidity of each part of the first folding region exposure part 122, the individual package 20 as a whole can be easily bent at a boundary between parts having different stiffnesses. When the free end 32 of the fastening tape 30 is to be picked with fingers when opening, the opening operation is performed such that the individual package 20 is bent, thereby further improving the ease of picking the free end 32. Can do. In general, since the rigidity of each part of the individual package 20 is proportional to the basis weight, in order to give the above-described rigidity difference to the first folding region exposed part 122, a relatively high rigidity portion has a high basis weight, The relatively low rigidity portion may have a low basis weight, and the intermediate rigidity portion may have an intermediate basis weight. In the first embodiment, the projecting portion 41 has a maximum width portion 42 extending over the entire length in the lateral direction Y of the absorbent core 4, and the rear convex portion 44 is bent by the first folding line 21. Therefore, the protrusion 41 is arranged in the vicinity of the central portion in the lateral direction Y on the first folding line 21 side, and the both ends in the lateral direction Y on the first folding line 21 side are arranged in the standard absorbent part 40. Are overlapped, the rigidity difference as described above is given to the first folding region exposed portion 122.

From the viewpoint of making the above-described operation and effects more reliable, the dimensions and the like of the protruding portion 41 including the maximum width portion 42, the front-side convex portion 43, and the rear-side convex portion 44 are set as follows. It is preferable.
The basis weight of the protrusion 41 is preferably 100 g / m ² or more, more preferably 200 g / m ² or more, and preferably 1500 g / m ² or less, more preferably 1200 g / m ² or less.

  7 to 9 show another embodiment of the individual package of the absorbent article of the present invention. In other embodiments described later, constituent parts different from the individual package 20 of the first embodiment will be mainly described, and the same constituent parts will be denoted by the same reference numerals and description thereof will be omitted. The description of the individual package 20 of the first embodiment is applied as appropriate to components that are not specifically described.

  In the individual packaging 20, the protruding portion 41 protrudes from the surface position (non-skin facing surface 40 b) of the standard absorbent portion 40 toward the non-skin side sheet 3 (see FIG. 5), but the individual packaging shown in FIG. 7. In 20A, on the contrary, the protrusion part 41 protrudes from the surface position (skin opposing surface 40a) of the standard absorption part 40 to the skin side sheet | seat 2 side. That is, in the individual package 20 </ b> A, the protruding portion 41 has a protruding portion 41 </ b> P that protrudes toward the skin side sheet 2 from the skin facing surface 40 a of the standard absorbent portion 40. Therefore, in the individual package 20A, the non-skin facing surface 40b and the non-skin side sheet 3 of the standard absorbent portion 40 are provided between the skin facing surface 40a of the standard absorbent portion 40 of the absorbent core 4 and the skin side sheet 2. A space portion similar to the space portion 47 (see FIG. 5) is formed. For this reason, the individual package 20 </ b> A is excellent in ease of picking the free end portion 32.

  The above-described individual packages 20 and 20A according to the first embodiment of the present invention are used as sealing and unsealing knobs for individual packages that are not in use, and are separate from the individual packages 20 and 20A. Although the tape 30 is provided, the individual package 20B according to the second embodiment of the present invention shown in FIG. 8 does not include such a fastening tape, but instead of the individual package 20B. The wrapping material 9 (one end in the longitudinal direction of the wrapping material 9 folded together with the sanitary napkin 1), which is a constituent member, functions as a sealing portion and an unsealing knob for an individual package in an unused state.

In the individual package 20B of the second embodiment, as shown in FIG. 8, the upper surface of the first folding region covering portion 121 or the upper surface of the first folding region covering portion 121 in the unused state of the individual packaging 20B is covered. The fastening adhesive 35 is disposed on the lower surface of the second folding region 13, and the second folding region 13 can be detachably secured to the first folding region covering portion 121 via the fastening adhesive 35. It is made like that. The fastening adhesive 35 in the second embodiment has a single continuous straight line in a plan view, and the second fold of the packaging material 9 at the overlapping portion of the first fold region covering portion 121 and the second fold region 13. A position spaced a predetermined distance in the vertical direction X from the vertical direction X end 91 on the region 13 side extends over substantially the entire length in the horizontal direction Y of the overlapping portion. The width (length in the longitudinal direction X) of the fastening adhesive 35 is preferably 0.5 to 5 mm. In the packaging material 9, the longitudinal direction end region 92 sandwiched between the longitudinal direction X end 91 of the packaging material 9 and the fastening adhesive 35 is not in relation to the first folding region covering portion 121 located immediately below it. It is adhesion and can function as a picking part for opening that is picked with fingers when opening the individual package 20B.

  Further, in the individual package 20B of the second embodiment, as shown in FIG. 8, the rear-side convex portion 44 that is an extension portion of the protruding portion 41 to the first folding region exposed portion 122 is a first folding line. The width gradually decreases with increasing distance from 21, and reaches the boundary between the first folding region exposed portion 122 and the second folding region 13, that is, the longitudinal X end 91 of the packaging material 9. More specifically, the rear side convex portion 44 straddles the longitudinal direction X end 91 of the packaging material 9 in the longitudinal direction X, and the top portion 441 overlaps the longitudinal direction end region 92 of the packaging material 9. And in the individual package 20B of 2nd Embodiment, as shown in FIG. 8 in the top view, the fastening adhesive 35 is an extension part to the 1st folding area | region exposed part 122 of the protrusion part 41. As shown in FIG. There is no overlap with the rear convex portion 44, and the standard absorbent portion 40 exists between the rear convex portion 44 and the fastening adhesive 35.

  Also in the individual package 20B of the second embodiment configured as described above, as in the individual packages 20 and 20A of the first embodiment, the rear that forms the boundary between the rear-side convex portion 44 and the standard absorbent portion 40. At the position where the vertical end 440 of the side convex portion 44 is formed, a step due to the thickness difference between the two is generated. And as above-mentioned in the individual package 20B, since the vertical direction edge part area | region 92 of the packaging material 9 has overlapped with the vertical direction edge 440 of the back side convex part 44, ie, has overlapped with the said level | step difference, it is an unopened state When the vertical end region 92 in the individual package 20B is to be picked with a finger according to a conventional method, the pressure when the vertical end region 92 is pushed from above with the tip of the finger (for example, the index finger) The individual package 20B is compressed in the thickness direction around the lower part of the longitudinal end region 92, and the members facing each other across the step, for example, the non-skin side sheet 3 and the standard absorption The part 40 is in close contact. As a result, in the individual package 20B, as shown in FIG. 9, the thickness of the fastening adhesive 35 and the lower part in the vicinity thereof is the thickness of the longitudinal end region 92 of the packaging material 9 and the lower part in the vicinity thereof. The vertical end region 92 is more likely to float from the upper surface of the first folding region exposed portion 122, so that the vertical end region 92 can be easily picked with fingers, and the subsequent opening operation Can be done smoothly and quickly.

  The shape in plan view of the fastening adhesive 35 is not limited to a continuous straight line parallel to the lateral direction Y as shown in FIG. 8 and may be any shape that extends in the lateral direction Y. For example, a curved line, a wavy line, a zigzag line, etc. Alternatively, the adhesive adhering portions and the adhesive non-adhering portions may be alternately arranged in the horizontal direction Y to form a discontinuous line extending in the horizontal direction Y as a whole. When the fastening adhesive 35 adheres discontinuously, the projecting portion 41 extends to the first folding region exposed portion 122 (rearward) with respect to an imaginary line connecting the adhesive attaching portions. It only needs to satisfy the positional relationship with the side convex portions 44) and the like. Further, there may be a plurality of fastening adhesives 35 extending in the lateral direction Y. In this case, the boundary between the first folding region exposed portion 122 and the second folding region 13 (the longitudinal direction X end 91 of the packaging material 9). It is only necessary that the fastening adhesive 35 closest to) satisfies the positional relationship with the extended portion (rear side convex portion 44) of the protruding portion 41 to the first folding region exposed portion 122 and the like. As the fastening adhesive 35, the same material as the material for forming the adhesive portion (adhesive) in the fastening tape 30 of the individual package 20 described above can be used.

As mentioned above, although this invention was demonstrated based on the embodiment, this invention can be changed suitably, without being restrict | limited to the said embodiment.
For example, a groove (not shown) may be formed in a portion that overlaps with the folding lines 21 and 22 in the protruding portion 41 (the front convex portion 43 and the rear convex portion 44). The protrusion 41 may have an opening on the skin facing surface (the surface facing the skin side sheet 2), and the protrusion 41 has an opening on the non-skin facing surface (the surface facing the non-skin side sheet 3). You may do it. Thus, the protrusion 4
If the groove is formed along the folding lines 21 and 22 in FIG. 1, the protruding portion 41 easily bends along the groove. Therefore, when opening the individual body 20, the individual body 20 follows the groove. By performing an opening operation that bends, the ease of picking the free end portion 32 can be further improved. Moreover, from a viewpoint of improvement of an absorptivity, leak-proof property, etc., it consists of various nonwoven fabrics between the skin side sheet | seat 2 and the absorptive core 4 (the said core wrap sheet | seat which coat | covers the skin opposing surface of the absorptive core 4). A liquid permeable sheet may be interposed.

All the parts of only the one embodiment described above can be used together as appropriate. For example, the individual package of the absorbent article in which a part of the packaging material folded together with the absorbent article, such as the individual package 20B, functions as a sealing part and an opening knob for the individual package. Similarly to the fastening tape 30 in FIG. 20, a fastening tape may be disposed on the upper surface of the individual package.
