Description

Absorbent article

The present invention relates to an absorbent article.

Conventionally, an absorbent article having a pair of leak-proof cuffs extending in the front-rear direction on both sides of an absorbent body having an absorbent core is widely known. The leak-proof cuff has an upright portion that can be erected by an elastic member having elasticity in the front-rear direction at least in the inseam region, an upright edge that serves as an upright fulcrum of the upright portion, and an upright portion in the front waist circumference area and the rear waist circumference region. It has a front-rear joint portion that is arranged on the outer side in the front-rear direction and is joined to the skin surface side of the absorbent body.

Patent Document 1 discloses an absorbent article in which the standing edge is arranged outside the absorption core in the width direction in the inseam region. Such absorbent articles can provide more excrement storage space than those with an upright edge located on the absorption core.

JP-A-2015-173871

In general, since the absorbent core has high rigidity, it tends to give a feeling of strangeness to the wearer, and the wearing comfort of the absorbent article may deteriorate. The amount of absorbent cores placed on the waistline (front waistline and / or rear waistline) side away from the inseam area to improve the comfort of the absorbent article while maintaining the absorption of excrement. It is possible to reduce. Here, by reducing the amount of the absorbent core, the front-rear joint may not overlap with the absorbent core in the plan view of the absorbent article. In this case, excrement may leak beyond the leak-proof cuff. In particular, there is a problem that excrement easily leaks beyond the leak-proof cuff in the sleeping posture.

Therefore, in the inseam region, the standing edge is arranged at least outside the absorption core in the width direction, and the front-rear joint is arranged at a position where it does not overlap with the absorption core in the plan view of the absorbent article. As for the sex article, an absorbent article capable of suppressing the leakage of excrement beyond the leak-proof cuff is desired.

The absorbent article according to one embodiment includes a front-rear direction, a width direction orthogonal to the front-rear direction, a thickness direction, a first waist circumference area, a second waist circumference area, the first waist circumference area, and the second waist circumference area. The inseam region sandwiched in the front-rear direction, the absorption core, the absorbent body having the absorption core, and the pair of leak-proof cuffs extending in the front-rear direction on both sides of the absorption body. Have. The leak-proof cuff has an upright portion that can be erected by contraction of the first elastic member having elasticity in the front-rear direction at least in the inseam region, an upright edge that serves as an upright fulcrum of the upright portion, and the first. It has a front-rear joint portion that is arranged outside the upright portion in the front-rear direction in the girth region and the second girth region, and is formed by being joined to the skin surface side of the absorbent body. The upright edge is arranged in the inseam region at least outside the absorption core in the width direction. In a plan view of the absorbent article, at least one of the front-rear joints is arranged at a position that does not overlap with the absorbent core. The absorbent article has a contracted portion that contracts in the anteroposterior direction due to contraction of a second elastic member arranged outside the erecting edge in the width direction in the inseam region.

(1) Outline of Embodiment At least the following matters will be clarified by the description of this specification and the accompanying drawings.
The absorbent article according to one embodiment includes a front-rear direction, a width direction orthogonal to the front-rear direction, a thickness direction, a first waist circumference area, a second waist circumference area, the first waist circumference area, and the second waist circumference area. The inseam region sandwiched in the front-rear direction, the absorption core, the absorbent body having the absorption core, and the pair of leak-proof cuffs extending in the front-rear direction on both sides of the absorption body. Have. The leak-proof cuff has an upright portion that can be erected by contraction of the first elastic member having elasticity in the front-rear direction at least in the inseam region, an upright edge that serves as an upright fulcrum of the upright portion, and the first. It has a front-rear joint portion that is arranged outside the upright portion in the front-rear direction in the girth region and the second girth region, and is formed by being joined to the skin surface side of the absorbent body. The upright edge is arranged in the inseam region at least outside the absorption core in the width direction. In a plan view of the absorbent article, at least one of the front-rear joints is arranged at a position that does not overlap with the absorbent core. The absorbent article has a contracted portion that contracts in the anteroposterior direction due to contraction of a second elastic member arranged outside the erecting edge in the width direction in the inseam region.

If the front and rear joints do not overlap with the highly rigid absorption core, the upright part will not be supported stably. Therefore, it was found that the absorption core expanded by absorbing the excrement pushes the upright portion outward in the width direction, and the upright portion tends to fall outward in the width direction. Especially in the sleeping position, if the anterior-posterior joint that is not located under the wearer (for example, the anterior-posterior joint on the front side in the back position) does not overlap the absorption core, the anterior-posterior joint is thickened by the absorption core. The movement in the longitudinal direction was difficult to be restricted, and the position of the front-rear joint was unstable. As a result, it was found that the front-rear joint could not stably support the upright portion, and the upright portion was particularly liable to fall outward in the width direction. As a result of diligent studies, the inventor has found that when the absorbent article has a contracted portion that contracts in the front-rear direction due to the contraction of the second elastic member, the standing portion does not easily fall outward in the width direction. Specifically, when the contracted portion contracts in the front-rear direction, the contracted portion is lifted toward the skin surface side. The upright edge on the inner side of the contraction portion in the width direction is lifted together with the contraction portion so that the upright portion can maintain its height. In addition, since the portion outside the width direction W from the standing edge is lifted more toward the skin surface side than the standing edge, the standing portion is less likely to fall outward in the width direction. As a result, it is possible to prevent excrement from leaking beyond the leak-proof cuff.

According to a preferred embodiment, the absorbent article may have an exterior body arranged on the non-skin surface side of the absorbent body in the first waist circumference region. The exterior body may have a waist elastic member having elasticity in the width direction. In a plan view of the absorbent article, at least a part of the front-rear joint may overlap with the waist elastic member. Since the front and rear joints are in close contact with the wearer's body due to the expansion and contraction of the waist elastic member, the position of the front and rear joints in the thickness direction is stable. As a result, the front-rear joint can stably support the upright portion, so that the upright portion can be prevented from falling outward in the width direction.

According to a preferred embodiment, the waist elastic member may extend continuously from at least one of the pair of leak-proof cuffs to the other in the first waist circumference region. The expansion and contraction of the elastic waist member causes the exterior body to come into close contact with the body between the pair of leak-proof cuffs. Therefore, the excrement that diffuses outward in the front-rear direction between the pair of leak-proof cuffs is less likely to diffuse to the outside in the front-rear direction than the waist elastic member, and the leakage of the excrement can be suppressed.

According to a preferred embodiment, the absorbent article may have an exterior body arranged on the non-skin surface side of the absorbent body in the first waist circumference region. The exterior body may have a waist elastic member having elasticity in the width direction. In a plan view of the absorbent article, the waist elastic member may be arranged at a position that does not overlap with the front-rear joint. By arranging the waist elastic member at a position that does not overlap with the front-rear joint, the contraction force in the width direction of the waist elastic member becomes difficult to work on the front-rear joint. As a result, it becomes difficult for the standing edge to approach the absorption core together with the front-rear joint portion, and it is possible to prevent the standing portion from being tilted outward in the width direction by the expanded absorption core.

According to a preferred embodiment, the absorbent article may have an exterior body arranged on the non-skin surface side of the absorbent body in the first waist circumference region. The exterior body may have a waist elastic member having elasticity in the width direction. A non-bonded region in which the absorbent body and the exterior body are not bonded may be provided. In a plan view of the absorbent article, the anterior-posterior junction may be located in the non-junction region. As a result, even if the exterior body contracts in the width direction due to the contraction of the waist elastic member, the region of the absorbent body that overlaps the non-joined region is not easily affected by the contraction of the waist elastic member. Therefore, the contraction force in the width direction of the waist elastic member becomes difficult to work on the front and rear joints. As a result, the upright fulcrum together with the front-rear joint becomes difficult to approach the absorption core due to the contraction of the waist elastic member, and the upright portion can be made difficult to be tilted outward in the width direction by the expanded absorption core.

According to a preferred embodiment, the second elastic member may have an effective portion in which elasticity is exhibited. In the front-rear direction, the outer edge of the effective portion in the front-rear direction may be arranged inside the front-rear joint. By arranging the outer edge of the effective portion inside the front-rear joint portion, the front-rear joint portion is less likely to be affected by the contraction of the second elastic member. This makes it difficult for the front-rear joint to be pulled inward in the front-rear direction, and makes it easier to maintain the position of the front-rear joint. Therefore, the contraction force of the first elastic member can be maintained in the upright portion, and the uprightness of the upright portion can be maintained. As a result, it is possible to prevent excrement from leaking beyond the leak-proof cuff.

According to a preferred embodiment, the absorbent article may have an exterior body arranged on the non-skin surface side of the absorbent body in the first waist circumference region. The exterior body may have a waist elastic member having elasticity in the width direction. In a plan view of the absorbent article, the outer end portion of the upright portion in the front-rear direction may overlap with the exterior body. When the absorbent article is attached, the wearer attaches the absorbent article after the outer body contracted by the waist elastic member is extended in the width direction. Therefore, when the outer end portion of the standing portion in the front-rear direction overlaps with the exterior body, the wearer can wear the absorbent article in a state where the standing portion is pulled outward in the width direction due to the extension of the exterior body. As a result, it is possible to prevent the standing portion from being tilted outward in the width direction by the expanded absorption core as compared with the case where the standing portion is arranged inward in the width direction.

As shown in FIG. 4, the edge 62E of the side sheet 62 may be arranged inside the width direction W of the absorbent body 41 with respect to the side edge in the width direction W. As a result, the edge 62E of the side sheet 62 is less likely to hit the wearer's skin, and deterioration of the touch can be suppressed.

The orthostatic elastic member 75 is an elastic member having elasticity in the front-rear direction L. Due to the contraction of the erecting elastic member 75, the erecting portion of the leak-proof cuff 70 can be erected on the skin surface side T1. That is, the orthostatic elastic member constitutes the "first elastic member" of the present invention. The orthostatic elastic member 75 may be composed of, for example, a rubber thread or an elastic sheet. The orthostatic elastic member 75 is composed of one or more elastic members. When the number of the orthostatic elastic members 75 is 2 or more, the orthostatic elastic members 75 may be arranged at intervals in the width direction W. In the present embodiment, the orthostatic elastic member 75 is composed of a first orthostatic elastic member 751 and a second orthostatic elastic member 752. As shown in FIG. 6, the first standing elastic member 751 is located closest to the skin surface side T1 when the leak-proof cuff 70 is standing. Therefore, the first standing elastic member 751 is arranged at the position closest to the apex Ap of the leak-proof cuff 70. On the other hand, the second standing elastic member 752 is located on the most non-skin surface side T2 when the leak-proof cuff 70 is standing. Therefore, the second standing elastic member 752 is arranged at the position farthest from the apex Ap (first fold FL1) of the leak-proof cuff 70 in the direction along the side sheet 62.

In the present embodiment, the side sheets 62 (pair of sheet layers 62p) are further folded back from the second fold FL2 as a base point. Therefore, in FIG. 4, the first orthostatic elastic member 751 is the second orthostatic elastic member. It is arranged outside the width direction W of 752. As shown in FIG. 4, the absorbent article 1 is formed between the second standing elastic member 752 (the elastic member located on the non-skin surface side T2 when the leak-proof cuff 70 is standing) and the standing edge 73 described later. , The joint portion (in-sheet joint portion) 63 for joining the pair of sheet layers 62p to each other with an adhesive may be provided. The joint portion 63 in the sheet may be, for example, an HMA (hot melt adhesive).

The leg elastic member 85 is an elastic member having elasticity in the front-rear direction L. The leg elastic member 85 is arranged outside the standing edge 73 in the width direction W. The leg elastic member 85 may be made of, for example, a rubber thread or an elastic sheet. The leg elastic member 85 has an effective portion in which elasticity is exhibited. In the drawings of the present specification, only the effective portion where the elasticity of the leg elastic member 85 is exhibited is shown. Therefore, in the present embodiment, as shown in FIG. 5, the front end edge 85FE and the rear end edge 85RE of the leg elastic member 85 are the outer end edges of the effective portion of the leg elastic member 85 in the front-rear direction L. In the front-rear direction L, the front end edge 85FE and the rear end edge 85RE of the leg elastic member 85 may be arranged inside the front-rear joint portion 711. The front end edge 85FE of the leg elastic member 85 may be arranged on the rear side of the front joint portion 711F in the front-rear direction L, and the rear end edge 85RE of the leg elastic member 85 is on the front side of the rear joint portion 711R in the front-rear direction L. May be placed in. The effective portion is a portion where the side sheet 62 is expanded and contracted together with the expansion and contraction of the leg elastic member 85. The invalid portion that is not an effective portion is a portion in which only the leg elastic member 85 expands and contracts, and the side sheet 62 does not expand and contract.

The leg elastic member 85 is composed of one or more elastic members. When the number of leg elastic members 85 is 2 or more, the leg elastic members 85 may be arranged at intervals in the width direction W. When the number of leg elastic members 85 and the number of standing elastic members 75 are two or more, the distance between the leg elastic members 85 may be narrower than the distance between the standing elastic members 75 in the width direction W. Further, the number of leg elastic members 85 may be larger than the number of standing elastic members 75. In the present embodiment, the leg elastic member 85 is composed of a first leg elastic member 851, a second leg elastic member 852, a third leg elastic member 853, and a fourth leg elastic member 854. Of the one or more leg elastic members 85, the first leg elastic member 851 is arranged on the innermost side in the width direction W, and the fourth leg elastic member 854 is arranged on the outermost side in the width direction W. A contraction portion 85R that contracts in the front-rear direction L due to contraction of the leg elastic member 85 is provided. The width of the contracted portion 85R is at least from the innermost leg elastic member 85 (that is, the first leg elastic member 851) to the outermost leg elastic member 85 (that is, the fourth leg elastic member 854) in the width direction W. Is the length of. As shown in FIG. 4, the length of the contracted portion 85R may be longer than the length from the innermost leg elastic member 85 to the outermost leg elastic member 85.

In the present embodiment, the orthostatic elastic member 75 and the leg elastic member 85 are sandwiched between a pair of sheet layers 62p. As a result, the standing elastic member 75 and the leg elastic member 85 are in contact with the sheet layer 62p. The region outside the width direction W with respect to the fourth leg elastic member 854 arranged on the outermost side in the width direction W may be a non-bonded region in which the pair of sheet layers 62p are not bonded to each other. The absorbent article 1 has a pair of leak-proof cuffs 70 extending in the front-rear direction L on both sides of the absorbent body 41. The leak-proof cuff 70 can stand on the skin side T1. The leak-proof cuff 70 may be composed of a composite telescopic sheet 60. The leak-proof cuff 70 may have a leak-proof joint 71, an upright portion 72, and an upright edge 73.

The leak-proof joint 71 is a portion that joins the side sheet 62 (composite telescopic sheet 60) to the absorbent main body 41. The leak-proof joint 71 may be made of an adhesive. In the inseam region S3, the inner edge of the leak-proof joint portion 71 in the width direction W is arranged outside the absorption core 50 in the width direction W. As shown in FIGS. 4 and 5, the leak-proof joint 71 is located outside the front-rear joint portion 711 located outside the standing edge 73 in the front-rear direction L and outside the width direction W from the standing edge 73. It may have a width joint 712 to be arranged. The front-rear joint portion 711 may have a front joint portion 711F arranged in the front waist circumference region S1 and a rear joint portion 711R arranged in the rear waist circumference region S2.

As shown in FIG. 5, at least one of the front and rear joints 711 is arranged at a position that does not overlap with the absorption core 50. Specifically, the front joint portion 711F is arranged on the front side of the front end edge of the absorption core 50. The rear joint portion 711R is arranged outside the side edge of the absorption core 50 in the width direction W. In the plan view of the absorbent article 1, at least a part of the front-rear joint portion 711 may overlap with the waist elastic member. Specifically, at least a part of the front joint portion 711F may overlap with the front waist elastic member 22. In the embodiment, the front waist elastic member 22 extending continuously in the width direction W from one side end portion of the front side exterior body 20 to the other side end portion is formed from one outer edge of the front joint portion 711F to the other. It continuously overlaps to the outer edge. The end portion of the front waist elastic member 22 exists between one side end portion and the other side end portion of the front side exterior body 20 so that a part of the front joint portion 711F overlaps with the front waist elastic member 22. You may. The rear joint portion 711R is the same as the front joint portion 711F. In the embodiment, the rear waist elastic member 32 continuously overlaps from one outer edge of the rear joint portion 711R to the other outer edge.

Further, as shown in FIG. 5, in the plan view of the absorbent article 1, the front-rear joint portion 711 may be arranged in the non-joint region NBR. Therefore, the front joint portion 711F may be arranged so as not to overlap the front main body joint portion 28 in the thickness direction T. The rear joint portion 711R may be arranged so as not to overlap the rear main body joint portion 38 in the thickness direction T. The upright portion 72 can be upright by one or more upright elastic members 75. The standing portion 72 stands up by the contraction of the standing elastic member 75. In the plan view of the absorbent article 1, the outer end portion of the standing portion 72 in the front-rear direction L may overlap with the exterior body 15. As shown in FIG. 5, the front end portion 72F of the upright portion 72 overlaps with the front exterior body 20. The rear end portion 72R of the standing portion 72 overlaps with the rear exterior body 30. The standing edge 73 serves as a standing fulcrum of the standing portion 72. The upright edge 73 is composed of an inner edge of the front-rear joint 711 (a rear edge of the front joint 711F and a front edge of the rear joint 711R) and an inner edge of the width joint 712.

The absorbent article 1 may have a pair of leg gathers 80. The leg gather 80 may be composed of a composite telescopic sheet 60. The leg gather 80 is arranged outside the upright edge 73 in the width direction W. The leg gather 80 has a contraction portion 85R. The contracted portion 85R contracts in the front-rear direction L in the inseam region S3 due to the contraction of the leg elastic member 85 arranged outside the standing end edge 73 in the width direction W. That is, the leg elastic member 85 constitutes the "second elastic member" of the present invention.

The leak-proof cuff 70 and the leg gather 80 are composed of a pair of sheet layers 62p. As shown in FIG. 6, the pair of sheet layers 62p are arranged on the outermost side in the width direction W from the position P1 in contact with the first standing elastic member 751 located closest to the skin surface when the leak-proof cuff 70 stands. It extends continuously to the position P2 in contact with the fourth leg elastic member 854. Therefore, both of the pair of sheet layers 62p overlap all the leg elastic members 85 in the thickness direction T. In the present embodiment, since the first fold FL1 is arranged on the leak-proof cuff 70, the pair of sheet layers 62p exceeds the first standing elastic member 751 and the first fold FL1, that is, the leak-proof cuff 70. It extends continuously to the apex Ap. Further, the pair of sheet layers 62p extends beyond the fourth leg elastic member 854 to the outside in the width direction W.

Further, as shown in FIGS. 4 and 6, the component members arranged on the non-skin surface side T2 of the side sheet 62 and directly or indirectly joined to the side sheet 62 are more than the standing edge 73. It may extend outward in the width direction W. The constituent members may overlap one or more leg elastic members 85 in the thickness direction T, and preferably overlap all leg elastic members 85.

In the present embodiment, the constituent member is at least one of a center sheet 43, a liquid-impermeable sheet 46, a non-skin surface sheet 47, and a non-skin side side sheet 48. As shown in FIGS. 4A and 4B, the center sheet 43 and the non-skin side side sheet 48 are directly joined to the side sheet 62. The liquid-impermeable sheet 46 is indirectly joined to the side sheet 62 via the non-skin side side sheet 48. The non-skin surface sheet 47 is directly bonded to the side sheet 62 (see FIG. 4A), and is indirectly bonded to the side sheet 62 via the liquid-impermeable sheet 46 and / or the non-skin side side sheet 48. ing.

In the absorbent article 1 of the present embodiment, the fourth leg elastic member 854 arranged on the outermost side in the width direction W from the first standing elastic member 751 located on the skin surface side T1 when the leak-proof cuff 70 stands up. Since the standing edge 73 exists in the meantime, a pair of sheet layers 62p exists in the vicinity of the standing edge 73. Therefore, as shown in FIG. 6, even if the excrement E flowing on the surface of the absorbent article 1 and moving to the outside in the width direction W exudes from the second sheet layer 622 to the outside in the width direction W, the first The sheet layer 621 can prevent exudation to the outside in the width direction W. As a result, leakage of excrement generated by exuding to the outside of the width direction W of the leakage-proof cuff can be suppressed. When the in-sheet joint portion 63 is provided between the second upright elastic member 752 and the upright end edge 73, the excrement is collected by the in-sheet joint portion 63 in the outer first sheet layer in the width direction W. It becomes difficult to reach 621 (see FIG. 6). Thereby, the leakage of the excrement generated by the excrement exuding to the outside of the width direction W of the leakage-proof cuff 70 can be suppressed.

Here, if the front-rear joint portion 711 does not overlap with the highly rigid absorption core 50, the upright portion 72 is not stably supported. Therefore, as shown in FIG. 7A, the absorption core 50 expanded by absorbing the excrement pushes the upright portion 72 to the outside of the width direction W, and the upright portion 72 easily falls to the outside of the width direction W. I found out. Especially in the sleeping position, when the front-rear joint portion 711 not arranged under the wearer (for example, the front joint portion 711F in the lying state) does not overlap with the absorption core 50, the front-rear joint portion 711 is the absorption core 50. The movement in the thickness direction T was difficult to be restricted, and the position of the front-rear joint portion 711 was unstable. As a result, it was found that the front-rear joint portion 711 could not stably support the upright portion 72, and the upright portion 72 was particularly liable to fall outward in the width direction W.

As a result of diligent studies by the inventor, when the absorbent article 1 has a contracted portion 85R that contracts in the front-rear direction L due to the contraction of the leg elastic member 85, the standing portion 72 is less likely to fall outward in the width direction W. I found. Specifically, as the contracted portion 85R contracts in the front-rear direction L, the contracted portion 85R is lifted to the skin surface side T1 as shown in FIG. By lifting the upright edge 73 together with the contracted portion 85R, the upright portion 72 can maintain its height. In addition, since the outside of the leak-proof joint 71 in the width direction W is lifted more toward the skin surface side T1 than the inside of the width direction W of the leak-proof joint 71, the width direction is wider than that of the leak-proof joint 71. The upright portion 72 located inside the sill is less likely to fall outward in the width direction W. As a result, it is possible to prevent the excrement E from leaking beyond the leak-proof cuff 70. Preferably, the contracted portion 85R is arranged in at least a part of the extension region extending outward in the width direction from the standing edge 73 located outside the standing portion 72 in the width direction.

Even when the front-rear joint portion 711 is arranged at a position where it does not overlap the absorption core 50, if the standing edge 73 overlaps the absorption core 50 in the inseam region S3, the absorption core 50 expands. The upright edge 73 (that is, the upright portion 72) moves to the skin surface side T1 together with the outer surface of the absorption core 50. Therefore, the problem that the expanded absorption core 50 tilts the upright portion 72 outward in the width direction does not occur. Further, since the pair of sheet layers 62p are continuously extended in the vicinity of the standing edge 73 in the width direction W, the rigidity in the vicinity of the standing edge 73 is higher than that in the case where a single sheet layer is extended, for example. It gets higher. Therefore, the standing portion 72 can be stably supported.

Further, since at least a part of the front-rear joint portion 711 overlaps with the waist elastic member WE in the thickness direction T, the front-rear joint portion 711 comes into close contact with the wearer's body due to the expansion and contraction of the waist elastic member WE. As a result, the position of the front-rear joint portion 711 in the thickness direction T is stable, and the front-rear joint portion 711 can stably support the upright portion 72. Therefore, it is possible to prevent the standing portion 72 from falling outward in the width direction W. Further, the waist elastic member WE overlapping the front-rear joint portion 711 extends continuously from one of at least one pair of leakage-proof cuffs 70 to the other. Due to the expansion and contraction of the waist elastic member WE, the exterior body 15 comes into close contact with the body between the pair of leakage-proof cuffs 70. Therefore, the excrement that diffuses to the outside of the front-rear direction L between the pair of leakage-proof cuffs 70 is less likely to diffuse to the outside of the front-rear direction L than the waist elastic member WE, and the leakage of the excrement can be suppressed.

Further, in the plan view of the absorbent article 1, the front-rear joint portion 711 is arranged in the non-joint region NBR. Even if the exterior body 15 contracts in the width direction W due to the contraction of the waist elastic member WE, the non-bonded region NBR of the absorbent main body 41 is not easily affected by the contraction of the waist elastic member WE. Therefore, the contraction force of the waist elastic member WE in the width direction W becomes difficult to act on the front-rear joint portion 711. As a result, the upright edge 73 together with the front-rear joint portion 711 becomes difficult to approach the absorption core 50, and the upright portion 72 can be made difficult to be tilted to the outside in the width direction W by the expanded absorption core 50.

Further, in the front-rear direction L, the front-end edge 85FE and the rear-end edge 85RE, which are the outer edge of the effective portion of the leg elastic member 85, are arranged inside the front-rear joint portion 711, so that the front-rear joint portion 711 becomes a leg. It becomes less susceptible to the shrinkage of the elastic member 85. As a result, the front-rear joint portion 711 is less likely to be pulled inward in the front-rear direction L, and the position of the front-rear joint portion 711 can be easily maintained. Therefore, the contraction force of the standing elastic member 75 can be maintained, and the standing property of the standing portion 72 can be maintained. As a result, it is possible to prevent excrement from leaking beyond the leak-proof cuff 70.

Further, generally, when the absorbent article 1 is attached, the wearer attaches the absorbent article 1 after the exterior body 15 contracted by the waist elastic member WE is extended in the width direction W. Therefore, when the front end portion 72F and the rear end portion 72R, which are the outer ends of the standing portion 72 in the front-rear direction L, overlap with the exterior body 15, the standing portion 72 moves to the outside in the width direction W due to the extension of the exterior body 15. When properly placed, the wearer can wear the absorbent article. As a result, the standing portion 72 can be made less likely to be tilted to the outside of the width direction W by the expanded absorption core 50 as compared with the case where the standing portion 72 is arranged inside the width direction W. Further, by increasing the number of leg elastic members 85 to be larger than the number of standing elastic members 75, the contracted portion 85R can be easily lifted to the skin surface side T1, and the standing edge 73 can be stably lifted. In addition, since the contracted portion 85R hits the wearer on the surface, the rigidity of the leg gather 80 can be increased, and the flatness of the leg gather 80 can be easily maintained. As a result, the leg gathers can be easily fitted to the wearer's skin on the surface, and the wearer's leg circumference can be suppressed from being locally pressed.

(3) Modification example Next, a modification example will be described with reference to FIG. FIG. 8 is a schematic plan view of the absorbent article according to the modified example. The same description as in the embodiment will be omitted. As shown in FIG. 8, in the plan view of the absorbent article 1, the waist elastic member WE may be arranged at a position that does not overlap with the front-rear joint portion 711. As a result, the contraction force of the waist elastic member WE in the width direction W becomes difficult to act on the front-rear joint portion 711. Therefore, the standing edge 73, which is the standing fulcrum of the standing portion 72 together with the front-rear joint portion 711, becomes difficult to approach the absorption core, and the standing portion 72 can be made difficult to be tilted to the outside in the width direction W by the expanded absorption core 50. .. In the absorbent article 1 according to the first modification, only the second front waist elastic member 222 is arranged as the waist elastic member WE in the front waist circumference region S1. Further, in the rear waist circumference region S2, all of the first rear waist elastic members 321 that continuously extend from one side end portion of the rear side exterior body 30 to the other side end portion are behind the front and rear joint portions 711. It is located on the side.

In the above, the leak-proof cuff 70 and the leg gather 80 are formed by one side sheet 62, but the present invention is not limited to this. The leak-proof cuff 70 and the leg gather 80 may be formed of separate sheets. In the above description, in the plan view of the absorbent article 1, both the front joint portion 711F and the rear joint portion 711R are arranged at positions that do not overlap with the absorption core 50, but the present invention is not limited to this.
