Description

The present invention relates to an absorbent article.

Conventionally, an absorbent article having an absorbent core and a waist elastic member arranged in a state of being extended in the width direction in a waist circumference region is known (see, for example, Patent Document 1).

The waist elastic member has a continuous elastic member and a discontinuous elastic member. The continuous elastic member extends continuously in the width direction from one outer portion of the waist circumference region to the other outer portion. The discontinuous elastic member does not extend continuously in the width direction, at least in the region overlapping the absorption core in the thickness direction.

The contraction of the continuous elastic member and the discontinuous elastic member fits the waistline area to the wearer's body and suppresses the waistline area from shifting toward the inseam side. On the other hand, in the region where the discontinuous elastic member does not continuously extend in the width direction, the contraction force of the waist elastic member is reduced, so that the absorption core can be suppressed from contracting in the width direction. As a result, the absorption area of the absorption core is secured, and the leakage of excrement from the waist opening side is suppressed.

Japanese Unexamined Patent Publication No. 2013-123447

The absorbent article of Patent Document 1 has leg side gathers that can stand up to the skin surface side. By standing the leg side gathers, it is possible to block the excrement that diffuses in the width direction on the absorber in the inseam area, and it is possible to suppress the lateral leakage of the excrement.

However, in the region where the contraction force of the waist elastic member is reduced, the force for directing the absorbent article toward the body is weak, so that the waist circumference region is separated from the body and a gap is likely to occur. Therefore, there is a problem that the excrement diffused on the absorber toward the waist circumference region is likely to cause lateral leakage by diffusing in the width direction.

Therefore, the present invention has been made to solve the above-mentioned problems, and suppresses leakage of excrement due to sagging of the inseam region in an absorbent article having a continuous elastic member and a discontinuous elastic member in the waist circumference region. The purpose is to provide an absorbent article that can be produced.

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 waist circumference area composed of a first waistline area and a second waistline area, the first waistline area, and the first waistline area. The inseam area sandwiched between the second waistline area in the front-rear direction, the absorbent body extending from the inseam area to at least the first waistline area in the front-rear direction, and the width direction in the waistline area. It has a waist elastic member that is arranged in an extended state. The waist elastic member includes a continuous elastic member that continuously extends in the width direction from one outer portion of the first waist circumference region to the other outer portion, and the width at least in the center of the waist circumference region in the width direction. It has a discontinuous elastic member that does not extend continuously in the direction. The absorbent body has an absorbent core containing the absorbent material and leg side gathers capable of standing upright on the skin surface side. The leg side gathers are formed on a standing portion that can be erected by contraction of a leg side elastic member arranged in a state of being extended in the front-rear direction, and outside the center of the absorption core in the width direction in the width direction. It has a front-rear fixing portion for fixing the leg side sheet to be arranged outside the upright portion in the front-rear direction. The continuous elastic member has an inner continuous elastic member arranged inside the front-rear direction with respect to the inner end edge of the front-rear fixed portion in the front-rear direction.

(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 waist circumference area composed of a first waistline area and a second waistline area, the first waistline area, and the first waistline area. The inseam area sandwiched between the second waistline area in the front-rear direction, the absorbent body extending from the inseam area to at least the first waistline area in the front-rear direction, and the width direction in the waistline area. It has a waist elastic member that is arranged in an extended state. The waist elastic member includes a continuous elastic member that continuously extends in the width direction from one outer portion of the first waist circumference region to the other outer portion, and the width at least in the center of the waist circumference region in the width direction. It has a discontinuous elastic member that does not extend continuously in the direction. The absorbent body has an absorbent core containing the absorbent material and leg side gathers capable of standing upright on the skin surface side. The leg side gathers are formed on a standing portion that can be erected by contraction of a leg side elastic member arranged in a state of being extended in the front-rear direction, and outside the center of the absorption core in the width direction in the width direction. It has a front-rear fixing portion for fixing the leg side sheet to be arranged outside the upright portion in the front-rear direction. The continuous elastic member has an inner continuous elastic member arranged inside the front-rear direction with respect to the inner end edge of the front-rear fixed portion in the front-rear direction.

Due to the contraction of the continuous elastic member, the area where the continuous elastic member is arranged comes into close contact with the wearer's body. On the other hand, inside the inner continuous elastic member in the front-rear direction, since the discontinuous elastic member does not continuously extend in the width direction, there is a low shrinkage region in which the contraction force in the width direction is low. As a result, the inside of the inner continuous elastic member in the front-rear direction is relatively easy to separate from the body side.

Here, since the inner continuous elastic member is arranged inside the front-rear fixed portion in the front-rear direction, the upright portion and the inner continuous elastic member located inside the front-rear fixed portion in the front-rear direction. Overlap in the thickness direction. Therefore, at the position where the standing portion and the inner continuous elastic member overlap, the standing portion can be brought into close contact with the body. As a result, it is possible to prevent the excrement from reaching the outside of the standing portion in the front-rear direction, and it is possible to prevent the excrement from diffusing in the width direction from the outside of the standing portion in the front-rear direction. On the other hand, on the inside in the front-rear direction from the position where the standing portion and the inner continuous elastic member overlap, the standing portion can stand from the overlapping position as a base point due to the contraction of the leg side elastic member, so that the standing portion can stand on the absorber in the width direction. It can block the spreading excrement. From the above, it is possible to suppress the leakage of excrement diffused on the absorber toward the waist circumference side.

According to a preferred embodiment, the inner continuous elastic member may be composed of a plurality of elastic members adjacent to each other in the front-rear direction. As a result, the standing portion can be brought into close contact with the body in a planar manner, and the standing portion can be firmly fixed at a position where the standing portion and the inner continuous elastic member overlap. Therefore, it is possible to prevent the excrement from reaching the outside in the anteroposterior direction from the standing portion. As a result, it is possible to suppress the diffusion of excrement in the width direction from the outside in the front-rear direction of the standing portion.

According to a preferred embodiment, the inner continuous elastic member may be composed of the absorption core and all the continuous elastic members overlapping in the thickness direction. As a result, the absorption core can be brought into close contact with the wearer's body due to the contraction of the inner continuous elastic member, and the excrement can be prevented from reaching the outside in the front-rear direction from the absorption core. In addition, since the inner continuous elastic member is arranged inside the front-rear fixed portion in the front-rear direction, it is possible to further prevent excrement from reaching the outside in the front-rear direction from the standing portion. it can. As a result, it is possible to suppress the diffusion of excrement in the width direction from the outside in the front-rear direction of the standing portion.

According to a preferred embodiment, the inner continuous elastic member may have the largest contractile force among the waist elastic members. By increasing the contraction force of the inner continuous elastic member, the standing portion can be brought into close contact with the body. As a result, it is possible to suppress the diffusion of excrement in the width direction from the outside in the front-rear direction of the standing portion. In addition, by bringing the standing portion into close contact with the body, the inner portion in the front-rear direction becomes easier to separate from the body side than the overlapping position of the standing portion and the inner continuous elastic member. This makes it easier to erect the upright portion with the overlapping position as the base point, and it is possible to block the excrement that diffuses in the width direction on the absorber.

According to a preferred embodiment, the inner continuous elastic member may have an innermost continuous elastic member arranged on the innermost side in the front-rear direction among the inner continuous elastic members. Among the waist elastic members, the contraction force of the innermost continuous elastic member may be the largest. The innermost continuous elastic member can be firmly attached to the body, and excrement can be prevented from reaching the outside in the front-rear direction of the innermost continuous elastic member. In addition, since the standing portion stands up from the position where the standing portion and the innermost continuous elastic member overlap, the standing portion is easily raised by making the contraction force of the innermost continuous elastic member the highest, and the absorbent body. It can block the excrement that spreads in the width direction on the top.

According to a preferred embodiment, the absorbent article may have an absorber that includes the absorbent core. The absorber may have a low basis weight region in which the basis weight of the absorbent material is lower than that of the surroundings. The inner continuous elastic member may overlap the low basis weight region in the thickness direction. Since the rigidity of the low basis weight region is lower than that of the surroundings, the contraction force of the inner continuous elastic member is less likely to be hindered by the rigidity of the absorber. In particular, since the basis weight of the absorbent material is lower in the low basis weight region than in the surrounding area, the absorber in the low basis weight region is relatively difficult to swell even if the absorber absorbs excrement. Therefore, the contraction of the overlapping continuous elastic member is unlikely to be inhibited even after excretion. Therefore, due to the contraction of the inner continuous elastic member, the region overlapping the inner continuous elastic member in the thickness direction can be further brought closer to the wearer's body side. Therefore, it is possible to prevent the excrement from reaching the outside of the inner continuous elastic member in the front-rear direction. In addition, the standing portion can be easily raised, and the excrement diffused in the width direction on the absorber can be blocked.

According to a preferred embodiment, the absorption core, the upright portion, and the inner continuous elastic member may overlap in the thickness direction. As a result, the standing portion is brought into close contact with the body side due to the contraction of the inner continuous elastic member. Therefore, the standing portion and the inner continuous elastic member are inside from the position in the front-rear direction from the position where the standing portion and the inner continuous elastic member overlap in the thickness direction. The standing part stands up. Since a part of the upright portion, which is the base point of the upright portion, is supported by the highly rigid absorption core, the position of a part of the upright portion can be stably fixed. Therefore, it is possible to make it easier to erect the inner erecting portion in the front-rear direction than a part of the erecting portion.

According to a preferred embodiment, the absorption core may have a squeezed portion in which the absorption core is squeezed in the thickness direction. The squeezed portion, the upright portion, and the inner continuous elastic member may overlap in the thickness direction. Since a part of the upright portion, which is the base point of the upright portion, is supported by the squeezed portion having high rigidity in the absorption core, the position of a part of the upright portion can be stably fixed. Therefore, it is possible to make it easier for the inner standing portion to stand up in the front-rear direction than a part of the standing portion.

According to a preferred embodiment, the inner edge of the front-rear fixing portion may be arranged in a region where the discontinuous elastic member does not continuously extend in the width direction. In the region where the discontinuous elastic member does not extend continuously in the width direction, the contraction force in the width direction is low, so that the absorption core does not easily shrink in the width direction and the front-rear fixed portion does not easily move inward in the width direction. As a result, it is possible to secure a storage space for excrement in the width direction, and it is possible to suppress the diffusion of excrement beyond the standing portion.

According to a preferred embodiment, the first girth region is a front girth region arranged on the ventral side of the wearer, and the second girth region is a rear girth region arranged on the dorsal side of the wearer. It may be there. The absorbent article includes a front exterior body arranged in the front waist circumference area, a rear exterior body arranged in the rear waist circumference region, an outer portion of the front exterior body in the width direction, and the rear exterior body. It may have a side joint that joins the outer side in the width direction. In the front waist circumference region, the inner continuous elastic member may be arranged 5% to 20% behind the front end edge of the side joint portion with respect to the total length of the absorbent article in the front-rear direction. Thereby, the inner continuous elastic member can be provided in the region where the dent at the lower end of the wearer's abdomen is likely to be arranged. Since the dent at the lower end of the abdomen of the wearer tends to generate a gap between the wearer and the front exterior body, the absorption core can be easily bent in the front-rear direction along the dent at the lower end of the abdomen of the wearer. Therefore, due to the contraction of the inner continuous elastic member, the region where the inner continuous elastic member is arranged comes into close contact with the wearer's body (specifically, the dent at the lower end of the abdomen). As a result, it is possible to prevent the excrement from reaching the outside in the front-rear direction from the standing portion. On the other hand, inside the inner continuous elastic member in the front-rear direction, the absorption core is bent in the front-rear direction, so that it is relatively easy to separate from the body side. As a result, the standing portion can stand up from the vicinity of the recess at the lower end of the abdomen, so that the excrement diffused in the width direction on the absorber can be blocked.

According to a preferred embodiment, the contraction force of the inner continuous elastic member overlapping the legside elastic member in the thickness direction may be larger than the contraction force of the legside elastic member. As a result, the leg side elastic member can be firmly fixed at a position where the leg side elastic member overlaps the inner continuous elastic member in the thickness direction. The standing portion can be firmly erected by the contraction force of the leg side elastic member.

The absorbent article 1 is, for example, a pants-type disposable diaper, a tape-type disposable diaper, a shorts-type sanitary napkin, or the like. The absorbent article 1 of the embodiment is a pants-type disposable diaper.

As shown in FIG. 1, the absorbent article 1 has a width direction W orthogonal to the front-rear direction L and the front-rear direction L. The anterior-posterior direction L is defined by the direction extending to the anterior side and the posterior side of the body. In other words, the anteroposterior direction L is a direction extending anterior-posteriorly in the deployed absorbent article 1. Further, the absorbent article 1 has both the front-rear direction L and the width direction W orthogonal to each other in the thickness direction T.

The absorbent body 20 is arranged at least in the inseam area S3. The absorbent body 20 extends in the front-rear direction L from the inseam area S3 to at least the front waist circumference area S1. Therefore, it may extend over the front waist circumference area S1, the rear waist circumference area S2, and the inseam area S3. The absorbent main body 20 overlaps the exterior body 50 in the thickness direction T in the front waist circumference area S1 and the rear waist circumference region S2. The exterior body 50 is arranged at least in the waist circumference area. The exterior body 50 may be composed of a front exterior body 50A arranged in the front waist circumference area S1 and a rear exterior body 50B arranged in the rear waist circumference area S2.

The side joint portion 16 may extend along the front-rear direction L in each of the front exterior body 50A and the rear exterior body 50B.

As shown in FIG. 1, with the side joint 16 formed, the absorbent article 1 has a waist opening 17 through which the wearer's torso is passed and a pair of legs into which the wearer's legs are inserted. The leg circumference opening 18 is formed. The waist opening 17 may be defined by the front end edge S1F of the front waist circumference area S1 and the rear end edge S2R of the rear waist circumference area S2.

In the pants-type absorbent article 1, the inseam region S3 may be defined by the inner edge of the side joint 16 in the front-rear direction L. The boundary between the front waist circumference region S1 and the inseam region S3 may be defined by the rear end edge 16R of the side joint portion 16 in the front waist circumference region S1. The boundary between the rear waist circumference region S2 and the inseam region S3 may be defined by the front end edge 16F of the side joint portion 16 in the rear waist circumference region S2. The inseam area S3 may be defined by the area provided with the leg circumference opening 18. The leg circumference opening 18 is a portion recessed inward in the width direction W from the outer edge of the absorbent article 1.

Further, the front end portion and the rear end portion in the present specification are portions that occupy a certain range in the front-rear direction L including the edge in the front-rear direction L, and the front end edge and the rear end edge are edges in the front-rear direction L. The outer edge includes a front edge and a trailing edge, and the outer edge includes a front edge and a trailing edge.

The absorbent main body 20 may have an absorbent body 30, a front surface sheet 41, a back surface sheet 42, and a leg side sheet 47. In an embodiment, the absorbent body 20 has a leg gather 70 and a leg side gather 80.

The absorber 30 has at least an absorption core 31. The absorption core 31 contains an absorption material. The absorption core 31 may contain, for example, ground pulp or a highly absorbent polymer (SAP), or a mixture thereof. As shown in FIG. 2, the absorption core 31 is arranged in the inseam region S3. Further, the absorption core 31 may be arranged in the front waist circumference area S1 and may be arranged in the rear waist circumference area S2. As shown in FIGS. 2 and 3, the absorption core 31 may extend from the front waist circumference region S1 to the rear waist circumference region S2 in the front-rear direction L.

The absorber 30 may have a core wrap 32 that covers the absorption core 31. The core wrap 32 may cover the absorption core 31 at least on the skin side T1 of the absorption core 31. The absorption core 31 may sandwich the absorption core 31 in the thickness direction T. The core wrap 32 may cover the absorption core 31 so as to sandwich the absorption core 31 in the width direction W. The core wrap 32 does not have to cover a part of the absorption core 31 (for example, a part of the non-skin surface side T2 of the absorption core 31). The core wrap 32 may be made of, for example, a tissue or a non-woven fabric.

The absorber 30 may have a low basis weight region LR in which the basis weight of the absorbent material is lower than that of the surroundings. In the present embodiment, the absorption core 31 is not arranged and the core wrap 32 is arranged in the low basis weight region LR in the thickness direction T. Therefore, the basis weight of the absorbing material in the low basis weight region LR is 0. The basis weight of the absorbing material may be 0, and the absorption core 31 may not substantially exist in the low basis weight region LR. A part of the absorption core 31 adjacent to the low basis weight region LR in the width direction W may be present by spilling into the low basis weight region LR. The “surroundings” here mean the periphery of the low basis weight region LR of the absorber 30, and do not include the region where the absorber 30 is not arranged.

On both outer sides of the low basis weight region LR in the width direction W, there may be a high basis weight region HR having a basis weight higher than the basis weight of the absorbing material of the low basis weight region LR. In the present embodiment, the high basis weight region HR is a region in which the absorption core 31 exists. The high basis weight region HR in the front waist circumference region S1 may be the basis weight of the absorption material equivalent to the region in which the absorption core 31 exists in the inseam region S3. For example, the difference between the basis weight of the absorption material of the absorption core 31 in the high basis weight region HR in the front waist circumference region S1 and the basis weight of the absorption material of the absorption core 31 in the inseam region S3 may be within 5%.

The absorption core 31 may have a squeezed portion in which the absorption core 31 is squeezed in the thickness direction T. The squeezing portion may be provided in the high basis weight region HR arranged on both outer sides of the low basis weight region LR in the width direction W.

The surface sheet 41 may be composed of a plurality of sheets. When the surface sheet 41 is composed of a plurality of sheets, the surface sheet 41 includes a sheet arranged only on the skin surface side T1 of the absorber 30 and a sheet of the absorber 30 in addition to the skin surface side T1 of the absorber 30. It may be composed of a sheet arranged up to T2 on the non-skin surface side.

The back sheet 42 is located on the non-skin surface side T2 of the absorber 30. The back sheet 42 may have liquid impermeable properties, and may be made of, for example, a film. As shown in FIG. 7, the back surface sheet 42 may be arranged on the skin surface side T1 of the leg side sheet 47 in the region overlapping the absorber 30 in the thickness direction T. The back sheet 42 may be arranged on the most non-skin surface side T2.

The leg side sheet 47 is arranged outside the width direction W of the absorption core 31 with respect to the center of the width direction W. The leg side seat 47 faces the wearer's skin. The leg side sheet 47 may extend in the width direction W so as to straddle the center of the absorbent article 1 in the width direction W on the non-skin surface side T2 of the absorption core 31. The leg side sheet 47 may be arranged on the non-skin surface side T2 of the back surface sheet 42 in a region overlapping the absorber 30 in the thickness direction T. The leg side sheet 47 may be made of, for example, a non-woven fabric.

As shown in FIG. 7, the leg side seat 47 may be composed of one seat member. The leg side sheet 47 may be folded back to the skin surface side T1 on both outer sides of the absorbent body 20. Specifically, the leg side seats 47 may be folded back from the non-skin surface side T2 to the skin surface side T1 along the first fold FL1 extending in the front-rear direction L on both outer sides of the absorbent body 20. The leg side sheet 47 may have a first portion 471 extending from the center of the absorbent body 20 in the width direction W to the first fold FL1 on the non-skin surface side T2 of the absorber 30 in the width direction W. The leg side sheet 47 may form the side edge of the absorbent body 20. Further, the leg side seat 47 may have a second portion 472 extending from the first portion 471 to the second fold FL2 in the width direction W.

Further, the leg side seat 47 may be further folded so as to sandwich the leg side elastic member 85. Specifically, the leg side seat 47 may be folded back from the skin surface side T1 to the non-skin surface side T2 along the second fold FL2 extending in the front-rear direction L. The leg side seat 47 may have a third portion 473 extending from the second fold FL2 to the third fold FL3 in the width direction W.

Further, the leg side seat 47 may be further folded back so as to sandwich the front and rear fixing portions 811 described later. Specifically, the leg side seat 47 may be folded back from the skin surface side T1 to the non-skin surface side T2 along the third fold FL3 extending in the front-rear direction L. The leg side seat 47 may have a portion extending from the third fold FL3 toward the absorption core in the width direction W.

The first front sheet 51F and the second front sheet 52F may be made of, for example, a non-woven fabric.

The rear exterior body 50B may be separated from the front exterior body 50A in the front-rear direction L. The rear exterior body 50B may be arranged on the non-skin surface side T2 of the absorbent body 20. The rear exterior body 50B may have a first rear seat 51R and a second rear seat 52R arranged on the non-skin surface side T2 of the first rear seat 51R. The first rear seat 51R may be arranged on the non-skin surface side T2 of the waist elastic member 55. The second rear seat 52R may be arranged on the skin surface side T1 of the waist elastic member 55. The first rear seat 51R may have a first front folded portion 51FP formed by folding the outer portion in the front-rear direction L to the skin surface side T1.

The first rear sheet 51R and the second rear sheet 52R may be made of, for example, a non-woven fabric.

The exterior body 50 has a waist elastic member 55 that is arranged in a state of being extended in the width direction W in the waist circumference region. The waist elastic member 55 may be composed of a thread-like or string-like elastic member extending in the width direction W. The length L in the front-rear direction (that is, the thickness of the elastic member) of the thread-like or string-like elastic member may be, for example, less than 5 mm. The waist elastic member 55 may have a continuous elastic member 55C and a discontinuous elastic member 55N.

The continuous elastic member 55C continuously extends in the width direction W from one outer portion of the front waist circumference region S1 (or the rear waist circumference region S2) to the other outer portion. Of the continuous elastic members 55C, the continuous elastic member 55C arranged in one of the front waist circumference area S1 and the rear waist circumference region S2 is referred to as a first continuous elastic member, and the continuous elastic member 55C arranged in the other is the second continuous elastic member 55C. It may be called an elastic member. For example, the continuous elastic member arranged in the front waist circumference area S1 is the first continuous elastic member, and the continuous elastic member arranged in the rear waist circumference area S2 is the second continuous elastic member.

The continuous elastic member 55C may have an overlapping continuous elastic member 55CO and a non-overlapping continuous elastic member 55CN. The overlapping continuous elastic member 55CO may overlap the absorption core 31 in the thickness direction T outside at least one of the discontinuous elastic members 55N in the front-rear direction L. In the embodiment, the overlapping continuous elastic member 55CO overlaps the absorption core 31 and the thickness direction T outside the inner discontinuous elastic member 55NA, which will be described later, in the front-rear direction L.

As shown in FIG. 5, in the embodiment, the continuous elastic member 55C overlaps the leg elastic member 75 outside at least one of the discontinuous elastic members 55N in the front-rear direction L. In the embodiment, the overlapping continuous elastic member 55CO overlaps the leg elastic member 75 in the thickness direction T. Hereinafter, as an example of the continuous elastic member 55C overlapping the leg elastic member 75 in the thickness direction T, the overlapping continuous elastic member 55CO will be described as an example. The overlapping continuous elastic member 55CO may overlap the low basis weight region LR in the thickness direction T. On the other hand, the non-overlapping continuous elastic member 55CN does not have to overlap the absorption core 31 in the thickness direction T. In the embodiment, the non-overlapping continuous elastic member 55CN does not overlap the absorbent body 20 in the thickness direction T. The non-overlapping continuous elastic member 55CN may include an elastic member that overlaps the absorbent body 20 in the thickness direction T.

The overlapping continuous elastic member 55CO may be composed of a plurality of elastic members arranged at intervals in the front-rear direction L. In the embodiment, the overlapping continuous elastic member 55CO is composed of four elastic members.

The overlapping continuous elastic member 55CO is 5% of the total length of the absorbent article 1 in the front-rear direction L (from the front edge to the trailing edge of the absorbent article 1) from the front edge 16F of the side joint 16 in the front waist circumference region S1. It may be placed 20% behind. Further, in the front waist circumference region S1, the overlapping continuous elastic member 55CO is 20% to 90% forward, preferably 40%, from the rear end edge 16R of the side joint portion 16 with respect to the total length of the side joint portion 16 in the front-rear direction L. It may be placed 70% forward, more preferably 45% to 65% forward.

The continuous elastic member 55C may have an inner continuous elastic member 55CI. The inner continuous elastic member 55CI is arranged inside the front-rear direction L with respect to the inner end edge 811E of the front-rear fixing portion 811 described later. As in this embodiment, the overlapping continuous elastic member 55CO may have an inner continuous elastic member 55CI. Therefore, the inner continuous elastic member 55CI may overlap the absorption core 31 in the thickness direction T. Further, the inner continuous elastic member 55CI may overlap the low basis weight region LR in the thickness direction T.

The inner continuous elastic member 55CI, like the overlapping continuous elastic member 55CO, is 5% to 20% behind the total length of the absorbent article 1 in the front-rear direction L from the front end edge 16F of the side joint portion 16 in the front waist circumference region S1. May be placed. Similarly, in the front waist circumference region S1, the inner continuous elastic member 55CI is 20% to 90% forward, preferably 40%, from the rear end edge 16R of the side joint portion 16 with respect to the total length of the side joint portion 16 in the front-rear direction L. It may be located 70% forward, more preferably 45% to 65% forward.

The inner continuous elastic member 55CI may be composed of a plurality of elastic members adjacent to each other in the front-rear direction L. In the present embodiment, of the four elastic members constituting the overlapping continuous elastic member 55CO, two elastic members arranged inside in the front-rear direction L are the inner continuous elastic member 55CI. Therefore, the inner continuous elastic member 55CI has a first inner continuous elastic member 55CIA and a second inner continuous elastic member 55CIB. The first inner continuous elastic member 55CIA is arranged on the innermost side in the front-rear direction L among the inner continuous elastic members 55CI. The second inner continuous elastic member 55CIB is adjacent to the first inner continuous elastic member 55CIA on the outside of the first inner continuous elastic member 55CIA in the front-rear direction L.

Among the waist elastic members 55, the inner continuous elastic member 55CI may have the largest contractile force. Further, among the waist elastic members 55, the contraction force of the first inner continuous elastic member 55CIA may be the largest.

In the present specification, the contraction force of the elastic member can be measured by, for example, the following method. The length H0 in the width direction W of the effective length portion of the elastic member is measured in a state where the absorbent article 1 is extended to the maximum in the front-rear direction L so that the wrinkles generated in the absorbent article 1 cannot be visually recognized. Next, the elastic member is removed from the absorbent article 1, and the length H1 of the effective length portion of the elastic member in the width direction W is measured. Then, the contraction force of the elastic member can be calculated by "contraction force = H0 / H1".

The continuous elastic member 55C may have a telescopic sheet 55CS that continuously extends in the width direction W from one outer portion of the front waist circumference region S1 to the other outer portion. The telescopic sheet 55CS is a sheet-shaped elastic member. The length of the telescopic sheet 55CS in the front-rear direction L may be, for example, 5 mm or more. The stretchable sheet 55CS may be composed of, for example, a stretchable resin film, a stretchable non-woven fabric, or a combination thereof.

The stretchable sheet 55CS has elasticity at least in the width direction W, and is arranged in a stretched state in the width direction W. The telescopic sheet 55CS may be arranged between the first front sheet 51F and the second front sheet 52F in the thickness direction T. The elastic sheet 55CS may be arranged on the skin surface side T1 of the thread-shaped or string-shaped waist elastic member 55.

In the state where the telescopic sheet 55CS is extended in the width direction W, the outer portion of the telescopic sheet 55CS in the width direction W may be fixed to the first front side sheet 51F and / or the second front side sheet 52F by the side joint portion 16. .. Further, in the stretchable sheet 55CS, for example, due to an adhesive portion (not shown) such as a hot melt type adhesive (HMA) or a sonic seal, at least a part of the main surface of the stretchable sheet 55CS is formed on the first front side sheet 51F and / or. And the second front seat 52F may be fixed.

The discontinuous elastic member 55N does not extend continuously in the width direction W at least in the center of the width direction W in the waist circumference region. The center of the girth region in the width direction W is at least a region from one outer end of the absorption core 31 to the other outer end.

In the region where the discontinuous elastic member 55N does not continuously extend in the width direction W, the contraction force in the width direction W is reduced as compared with the region where the discontinuous elastic member 55N continuously extends in the width direction W. There is. As a method of providing a region in which the discontinuous elastic member 55N does not continuously extend in the width direction W, for example, the following method can be used.

In the first method, the contraction region may be reduced by not arranging the discontinuous elastic member 55N in the extended state. For example, an adhesive for fixing the discontinuous elastic member 55N (for example, a hot melt type adhesive (HMA)) is arranged in a region where the discontinuous elastic member 55N is arranged in an extended state to reduce the shrinkage force. No adhesive for fixing the discontinuous elastic member 55N is arranged in the region (hereinafter referred to as the low shrinkage region LER). As a result, the discontinuous elastic member 55N is fixed in the stretched state in the region where the adhesive is arranged. In the region where the adhesive is not arranged and sandwiched between the regions where the adhesive is arranged in the width direction W, the discontinuous elastic member 55N is maintained in the stretched state, so that the discontinuous elasticity is maintained in the region. By cutting the member 55N, the cut discontinuous elastic member 55N contracts. As a result, the discontinuous elastic member 55N having contractility (that is, in the extended state) is not arranged in the low shrinkage region LER, and the low shrinkage region LER can be provided. Therefore, in the low shrinkage region LER, the discontinuous elastic member 55N does not continuously extend in the width direction W.

When the low shrinkage region LER (hereinafter, the first low shrinkage region LER1) is provided by the above-mentioned first method, the discontinuous elastic member 55N may have a fixed portion and a non-fixed portion. The fixed portion is a portion arranged in an extended state. The non-fixed portion is a portion that exists in the natural state without being fixed in the extended state.

In the second method, the contraction force of the discontinuous elastic member 55N may be reduced by cutting (cutting) the discontinuous elastic member 55N fixed to the low contraction region LER at a plurality of points. As a result, the discontinuous elastic member 55N does not continuously extend in the width direction W. In this case, even if the discontinuous elastic member 55N is fixed in the extended state, the contraction force of the discontinuous elastic member 55N is reduced. In addition, since the discontinuous elastic member 55N in which the contraction force remains is arranged (fixed) in the low shrinkage region LER (hereinafter, the second low shrinkage region LER2) provided by the above-mentioned second method, The contraction force of the second low contraction region LER2 is generally larger than the contraction force of the first low contraction region LER1.

The discontinuous elastic member 55N may have an inner discontinuous elastic member 55NA and an outer discontinuous elastic member 55NB. The inner discontinuous elastic member 55NA is arranged inside the overlapping continuous elastic member 55CO in the front-rear direction L. The outer discontinuous elastic member 55NB is arranged outside the overlapping continuous elastic member 55CO in the front-rear direction L.

As shown in FIG. 5, in the first method, the inner discontinuous elastic member 55NA is not continuously extended in the width direction W, so that the first low shrinkage region LER1 is provided. In the first low shrinkage region LER1, the inner discontinuous elastic member 55NA having shrinkage in the width direction W is not arranged. Inner discontinuous elastic members 55NA are arranged on both outer sides of the first low shrinkage region LER1 in the width direction W.

On the other hand, according to the second method, the outer discontinuous elastic member 55NB is not continuously extended in the width direction W, so that the second low shrinkage region LER2 is provided. In the second low shrinkage region LER2, the outer discontinuous elastic member 55NB is arranged. The contraction force of the outer discontinuous elastic member 55NB arranged in the second low contraction region LER2 is larger than the contraction force of the outer discontinuous elastic member 55NB arranged outside the width direction W of the second low contraction region LER2. Is also low.

Next, the leg gather 70 will be described. The leg gather 70 is a gather provided outside the absorption core 31 in the width direction W. The leg gathers 70 may be provided around the leg opening 18 and the leg opening 18. Further, it may be provided on the non-skin surface side T2 of the leg side gather 80.

The leg gather 70 is pulled up toward the wearer's body by the contraction of the leg elastic member 75. The leg gather 70 has a leg elastic member 75. The leg elastic member 75 is arranged outside the absorption core 31 in the width direction W in the inseam region S3. The leg elastic member 75 is arranged in a state of being extended in the front-rear direction L. The leg elastic member 75 extends in the front-rear direction L at least in the inseam region S3. The leg elastic member 75 is arranged in the front waist circumference region S1. The leg elastic member 75 may be arranged in the rear waist circumference region S2.

As shown in FIG. 7, in the present embodiment, the leg elastic member 75 may be arranged on the leg side seat 47. The leg elastic member 75 may be arranged between the leg side sheet 47 and the back surface sheet 42 in the thickness direction T. Further, the leg elastic member 75 may be arranged so as to be sandwiched between the leg side seats 47 in the thickness direction T. Among the plurality of leg elastic members 75, some leg elastic members 75 (for example, the leg elastic members 75 arranged on the outermost side in the width direction W) are sandwiched between the leg side seats 47 in the thickness direction T. May be placed. The leg elastic member 75 may be fixed to the leg side sheet 47 or may be fixed to the back surface sheet 42. Therefore, the leg gather 70 may be composed of a leg side seat 47 in addition to the leg elastic member 75. The leg gather 70 may be composed of a leg elastic member 75, a leg side sheet 47, and a back surface sheet 42. The leg elastic member 75 is arranged on another sheet member (a sheet member other than the back surface sheet 42 and the leg side sheet 47) arranged outside the absorption core 31 in the width direction W in the thickness direction T. It may have been done.

As shown in FIG. 5, in the embodiment, the leg elastic member 75 overlaps the continuous elastic member 55C in the thickness direction T outside at least one of the discontinuous elastic members 55N in the front-rear direction L. The leg elastic member may overlap the overlapping continuous elastic member 55CO in the thickness direction T. The leg elastic member 75 may overlap two or more elastic members among the plurality of elastic members constituting the overlapping continuous elastic member 55CO in the thickness direction T. In FIG. 5, the leg elastic member 75 overlaps the four overlapping continuous elastic members 55CO in the thickness direction T. Further, the leg elastic member 75 overlaps the inner continuous elastic member 55CI in the thickness direction T. Further, the leg elastic member 75 may overlap the discontinuous elastic member 55N in the thickness direction T. The leg elastic member 75 may overlap the inner discontinuous elastic member 55NA in the thickness direction T. The leg elastic member 75 may be arranged at a position where it does not overlap with the outer discontinuous elastic member 55NB in the thickness direction T.

The leg elastic member 75 may overlap the telescopic sheet 55CS as the continuous elastic member 55C in the thickness direction T. Therefore, in the front-rear direction L, the inner edge of the telescopic sheet 55CS in the front-rear direction L may be inside the outer edge of the leg elastic member 75 in the front-rear direction L.

The leg elastic member 75 may be arranged at a position that does not overlap with the continuous elastic member 55C in the thickness direction T in the rear waist circumference region S2. The leg elastic member 75 may overlap with the discontinuous elastic member 55N in the thickness direction T in the rear waist circumference region S2, or may be arranged at a position where the leg elastic member 75 does not overlap.

As shown in FIG. 5, the length L1 of the portion where the leg elastic member 75 overlaps the front waist circumference region S1 in the thickness direction T overlaps with the rear waist circumference region S2 in the thickness direction T. The length of the portion in the front-rear direction L may be longer than the length L2. When the leg elastic member 75 overlaps the front waist circumference area S1 and does not overlap the rear waist circumference region S2 in the thickness direction T, the length L2 = 0, so that the length L1 is longer than the length L2.

The overlapping continuous elastic member 55CO that overlaps the leg elastic member 75 in the thickness direction T may have the largest contraction force among the waist elastic members 55. When the overlapping continuous elastic member 55CO is composed of a plurality of elastic members, any one of the plurality of elastic members may have the largest contraction force among the waist elastic members 55. Of the overlapping continuous elastic members 55CO overlapping the leg elastic member 75 and the thickness direction T, the overlapping continuous elastic member 55CO located on the innermost side in the front-rear direction L (in FIG. 5, the innermost continuous elastic member 55CIA) has the highest contraction force. It can be big.

Further, the contraction force of the overlapping continuous elastic member 55CO that overlaps the leg elastic member 75 in the thickness direction T may be larger than the contraction force of the leg elastic member 75. The contraction force of one or more overlapping continuous elastic members 55CO among the overlapping continuous elastic members 55CO may be larger than the contraction force of the leg elastic member 75. The contraction force of all overlapping continuous elastic members 55CO may be larger than the contraction force of the leg elastic member 75. Alternatively, the contraction force of the leg elastic member 75 may be larger than the contraction force of the overlapping continuous elastic member 55CO that overlaps the leg elastic member 75 in the thickness direction T.

Here, as shown in FIG. 8A, in the conventional absorbent article, the leg elastic member 75 does not overlap the continuous elastic member 55C in the thickness direction T. In this case, since the force on the skin surface side T1 is not sufficiently applied to the leg elastic member 75 in the front waist circumference region S1, the position of the leg elastic member 75 is difficult to be fixed. Therefore, the leg elastic member 75 can easily be separated from the body or can easily move to the rear in the front-rear direction L. Therefore, due to the contraction of the leg elastic member 75, not only the force in the direction toward the front waist circumference region S1 but also the force in the direction toward the rear waist circumference region S2 acts on the leg elastic member 75. As a result, as shown in FIG. 8A, when the wearer raises the leg in the lying posture, the leg elastic member 75 arranged in the inseam area S3 is sufficiently pulled up to the front waist circumference area S1 side. As shown by the outline 20L of the absorbent main body 20, the inseam region S3 is likely to be maintained in a hanging state. In this case, since the absorption core 31 is separated from the wearer's body, there is a risk of lateral leakage of excrement. In particular, after excretion, the inseam region S3 hangs down due to the weight of the absorption core 31 that has absorbed the excrement, so that the excrement that the absorption core 31 could not absorb may leak in the width direction W in the inseam region S3.

As described above, in the embodiment, the leg elastic member 75 overlaps the continuous elastic member 55C in the thickness direction T. Since the leg elastic member 75 is subjected to a force on the skin surface side T1 due to the contraction of the continuous elastic member 55C, as shown in FIG. 8B, the leg elastic member 75 arranged in the front waist circumference region S1 is the continuous elastic member 55C. It becomes easy to be fixed at the position P1 that overlaps with the thickness direction T. As a result, the leg elastic member 75 contracts, and a force F acts on the leg elastic member 75 in the direction toward the position P1. Therefore, for example, as shown in FIG. 8B, when the wearer raises the leg in the lying posture, the leg elastic member 75 arranged in the inseam area S3 is pulled up to the front waist circumference area S1 side. .. In FIG. 8A, as shown by the outline 20L of the absorbent body 20, the inseam region S3 is pulled up by pulling up the leg elastic member 75. As a result, the sagging of the inseam region S3 can be suppressed, and the absorption core 31 can be brought closer to the wearer's body.

Further, the region overlapping the continuous elastic member 55C in the thickness direction T is brought into close contact with the wearer's body side due to the contraction of the continuous elastic member 55C, so that the region is less likely to shift to the inseam region S3 side. In addition, the continuous elastic member 55C overlaps with the leg elastic member 75 on the outside of the inner discontinuous elastic member 55NA in the front-rear direction L. In the region where the inner discontinuous elastic member 55NA does not extend continuously in the width direction W, the contraction force is reduced as compared with the portion where the inner discontinuous elastic member 55NA extends continuously, so that the continuous elastic member It is possible to suppress the front waist circumference region S1 from shrinking in the width direction W inside the front-rear direction L (that is, on the inseam region S3 side) with respect to 55C (overlapping continuous elastic member 55CO in the embodiment), and to secure an absorption area. .. Therefore, it is possible to suppress lateral leakage of excrement due to hanging of the inseam area S3 while suppressing the front waist circumference area S1 from shrinking in the width direction W.

Further, the leg elastic member 75 may be arranged at a position that does not overlap with the continuous elastic member 55C in the thickness direction T in the rear waist circumference region S2. As a result, as shown in FIG. 8A, in a sleeping posture in which the front waist circumference area S1 is on the upper side and the rear waist circumference area S2 is on the lower side, the end portion of the leg elastic member 75 on the rear waist circumference area S2 side becomes the rear waist circumference. Since the position is not fixed by the continuous elastic member 55C of the region S2, the inseam region S3 is difficult to be pulled down to the rear waist circumference region S2 side due to the contraction of the leg elastic member 75, and the inseam region S3 is moved to the front waist circumference by the contraction of the leg elastic member 75. It can be easily pulled up to the region S1 side. Thereby, in the sleeping posture, the front waist circumference area S1 can be easily brought close to the wearer's body, and the lateral leakage of excrement due to the hanging of the inseam area S3 can be suppressed.

Further, the first waist circumference region where the leg elastic member 75 overlaps the continuous elastic member 55C in the thickness direction T may be the front waist circumference region S1. The wearer often sleeps (lays down) on his back with the ventral side facing up. Therefore, by facilitating the inseam area S3 to be pulled up to the ventral side by the contraction of the leg elastic member 75, it is possible to easily suppress the lateral leakage of excrement due to the hanging of the inseam area S3 in the sleeping posture.

Further, the leg elastic member 75 may have an overlapping continuous elastic member 55CO. As a result, the absorption core that overlaps the overlapping continuous elastic member 55CO in the thickness direction is brought into close contact with the wearer's body side due to the contraction of the overlapping continuous elastic member 55CO, so that it is difficult to shift to the inseam region side. The weight of the absorption core 31 (particularly, the absorption core 31 that has absorbed excrement) can prevent the entire absorption core 31 from shifting toward the inseam region. Further, inside the overlapping continuous elastic member 55CO in the front-rear direction L (that is, on the inseam region S3 side), the inner discontinuous elastic member 55NA suppresses the absorption core 31 from shrinking in the width direction to secure an absorption area. Can be done.

Further, the leg elastic member 75 may overlap with two or more elastic members among the plurality of elastic members constituting the continuous elastic member 55C in the thickness direction T. The leg elastic member 75 arranged in the front waist circumference region S1 is more easily fixed to the front waist circumference region S1 by overlapping with two or more continuous elastic members 55C in the thickness direction T. As a result, the leg elastic member 75 contracts, so that the leg elastic member 75 arranged in the inseam area S3 can be easily pulled up toward the front waist circumference area S1 side, and the inseam area S3 can be easily pulled up.

Further, in the front waist circumference region S1, the continuous elastic member 55C overlapping the leg elastic member 75 in the thickness direction T is 5% to 20 with respect to the total length of the absorbent article 1 in the front-rear direction L from the front end edge 16F of the side joint portion 16. % May be placed behind. As a result, the continuous elastic member 55C can be provided in the region where the recess at the lower end of the wearer's abdomen is likely to be arranged. Since the dent at the lower end of the abdomen of the wearer tends to generate a gap between the wearer and the front exterior body 50A, the absorber 30 (absorption core 31) is moved to L in the front-rear direction along the dent at the lower end of the abdomen of the wearer. It can be easily bent. As a result, the absorber 30 can be arranged along the abdomen that swells from the recess at the lower end of the wearer's abdomen in the anteroposterior direction L, and the absorber 30 can be fitted to the wearer's body in the anteroposterior direction L. ..

Further, the continuous elastic member 55C that overlaps the leg elastic member 75 in the thickness direction T may have the largest contraction force among the waist elastic members 55. As a result, the region in which the continuous elastic member 55C is arranged has a strong force of coming into close contact with the wearer's body side due to the contraction of the continuous elastic member 55C, so that the region is less likely to shift to the inseam region S3 side. As a result, the leg elastic member 75 can be firmly fixed while suppressing the entire absorption core 31 from shifting toward the inseam region S3.

Further, the contraction force of the continuous elastic member 55C that overlaps the leg elastic member 75 in the thickness direction T may be larger than the contraction force of the leg elastic member 75. As a result, the leg elastic member 75 can be firmly fixed at a position where the leg elastic member 75 overlaps the continuous elastic member 55C in the thickness direction T. The inseam region can be pulled up firmly by the contraction force of the leg elastic member 75, and the sagging of the inseam region S3 can be suppressed.

Further, the continuous elastic member 55C that overlaps the leg elastic member 75 in the thickness direction T may overlap the low basis weight region LR and the thickness direction T. Since the rigidity of the low basis weight region LR is lower than that of the surroundings, the contraction force of the continuous elastic member 55C is less likely to be hindered by the rigidity of the absorber 30. Due to the contraction of the continuous elastic member 55C, the absorber 30 in the low basis weight region LR can be brought closer to the wearer's body side, and the front waist circumference region S1 can be fitted to the wearer's body. In particular, since the absorption material in the low basis weight region LR has a lower basis weight than the surroundings, even if the absorber 30 absorbs excrement, the absorber 30 in the low basis weight region LR is relatively difficult to swell. Therefore, the contraction of the continuous elastic member 55C is less likely to be inhibited even after excretion, and the front waist circumference region S1 can be fitted to the wearer's body even after excretion. As a result, it is possible to suppress the displacement of the front waist circumference region S1 toward the inseam region S3 and the leakage of excrement from the waist opening 17 side.

Further, the discontinuous elastic member 55N may further have an outer discontinuous elastic member 55NB arranged outside the continuous elastic member 55C in the front-rear direction L, which overlaps with the leg elastic member 75 in the thickness direction T. As a result, outside the continuous elastic member 55C that overlaps the leg elastic member 75 and the continuous elastic member 55C in the thickness direction T, the front waist circumference is not tightened toward the wearer's body side on the center side of the width direction W of the front waist circumference region S1. While fitting the region S1, on the outer side of the wearer, the front waist circumference region S1 can be fitted along the wearer's body by the contraction of the outer discontinuous elastic member 55NB.

Next, the leg side gather 80 will be described. The leg side gather 80 is a gather that can stand up on the skin side T1. It may be provided on the skin surface side T1 of the leg side gather 80. The leg side gather 80 may have a fixed portion 81 and an upright portion 82.

The fixing portion 81 fixes the leg side seat 47. Specifically, the fixing portion 81 fixes a part of the leg side seat 47 to which the leg side elastic member 85 is fixed to a member located on the non-skin surface side T2 of the part of the leg side seat 47. .. In the embodiment, the third portion 473 of the leg side seat 47 is fixed to the fourth portion 474 by the fixing portion 81. The fixing portion 81 may be composed of, for example, an adhesive portion such as a hot melt type adhesive (HMA) or a sonic seal.

The fixing portion 81 includes a front-rear fixing portion 811 for fixing the leg side seat 47 on the outside of the standing portion 82 in the front-rear direction L, and a width fixing portion for fixing the leg side seat 47 on the outside of the standing portion 82 in the width direction W. It has 812 and. The front-rear fixing portion 811 may have a front fixing portion arranged in the front waist circumference region S1 and a rear fixing portion arranged in the rear waist circumference region S2.

In the embodiment, the front-rear fixing portion 811 has an inner edge 811E inside the front-rear direction L. The continuous elastic member 55C is arranged inside the front-rear fixing portion 811 in the front-rear direction L with respect to the inner end edge 811E. Specifically, the inner continuous elastic member 55CI is arranged inside the front-rear fixing portion 811 in the front-rear direction L with respect to the inner end edge 811E. Further, the overlapping continuous elastic member 55CO other than the inner continuous elastic member 55CI is arranged outside the inner end edge 811E of the front-rear fixing portion 811 in the front-rear direction L. Further, the front-rear fixing portion 811 has an inner edge 811S inside in the width direction W. The inner edge 811S of the front-rear fixing portion 811 may be arranged in the low shrinkage region LER in which the discontinuous elastic member 55N does not continuously extend in the width direction W.

As shown in FIG. 6, the absorption core 31, the upright portion 82, and the inner continuous elastic member 55CI may overlap in the thickness direction T. Further, when the absorption core 31 is provided with the squeezed portion, the squeezed portion, the standing portion 82, and the inner continuous elastic member 55CI may overlap in the thickness direction T.

As shown in FIG. 7B, the upright portion 82 can be upright by contraction of the leg side elastic member 85. The upright portion 82 can stand up with the boundary between the upright portion 82 and the fixed portion 811 as a base point. Specifically, the upright portion 82 can stand up with the inner edge of the width fixing portion 812 in the width direction W as a base point in the width direction W, and in the front-rear direction L, inside the front-rear direction L of the front-rear fixing portion 811. It can stand up with the edge 811E as the base point. However, as will be described later, when the continuous elastic member 55C (inner continuous elastic member 55CI) is arranged inside the front-rear direction L with respect to the inner end edge 811E of the front-rear fixed portion 811 in the front-rear direction L, it contracts. The portion can stand up with the position SP overlapping the inner continuous elastic member 55CI in the thickness direction T as a base point.

The leg side elastic member 85 is arranged on the leg side seat 47 in a state of being extended in the front-rear direction L. In the present embodiment, the leg side elastic member 85 is sandwiched between the leg side seats 47. The leg side elastic member 85 may be composed of a single elastic member, or may be composed of a plurality of elastic members arranged at intervals in the width direction W. In this embodiment, it is composed of two elastic members. The leg side elastic member 85 may be composed of a thread-like or string-like elastic member extending in the front-rear direction L. The leg side elastic member 85 is arranged on the leg side seat 47 in a state of being extended in the front-rear direction L. In the present embodiment, the leg side elastic member 85 is sandwiched between the leg side seats 47. Specifically, it is arranged between the second portion 472 and the third portion 473 of the leg side seat 47. The leg side elastic member 85 may be fixed to at least one of the second portion 472 and the third portion 473 of the leg side seat 47.

The contraction force of the inner continuous elastic member 55CI that overlaps the leg side elastic member 85 in the thickness direction T may be larger than the contraction force of the leg side elastic member 85.

Here, as shown in FIG. 9A, in the conventional absorbent article, the continuous elastic member 55C is not arranged inside the front-rear fixing portion 811 in the front-rear direction L with respect to the inner end edge 811E. Therefore, as usual, the standing portion 82 stands up with the inner end edge 811E of the front-rear fixed portion 811 as a base point. For this reason, the vicinity of the inner edge 811E of the front-rear fixing portion 811 is likely to be separated from the wearer's body, and a gap G is likely to be generated between the absorbent article and the body. Therefore, there is a problem that the excrement diffused on the absorber 30 toward the waist circumference region is diffused in the width direction W, so that lateral leakage is likely to occur.

As described above, in the embodiment, the continuous elastic member 55C has an inner continuous elastic member 55CI arranged inside the front-rear direction L with respect to the inner end edge 811E of the front-rear fixing portion 811. As shown in FIG. 9B, since the inner continuous elastic member 55CI is arranged inside the front-rear direction L with respect to the inner end edge 811E of the front-rear fixing portion 811, it is inside the front-rear direction L with respect to the front-rear fixing portion 811. The located standing portion 82 and the inner continuous elastic member 55CI overlap each other in the thickness direction T. Therefore, at the position where the standing portion 82 and the inner continuous elastic member 55CI overlap, the standing portion 82 can be brought into close contact with the body. As a result, it is possible to prevent the excrement from reaching the outside of the upright portion 82 in the front-rear direction L, and the excrement is diffused from the outside of the upright portion 82 in the front-rear direction L in the width direction W. Can be suppressed. On the other hand, inside the position SP where the standing portion 82 and the inner continuous elastic member 55CI overlap in the front-rear direction L, the standing portion 82 can stand from the overlapping position SP as a base point due to the contraction of the leg side elastic member 85. The excrement that diffuses in the width direction W on the absorber 30 can be blocked.

Further, due to the contraction of the continuous elastic member 55C, the region where the continuous elastic member 55C is arranged comes into close contact with the wearer's body. On the other hand, inside the inner continuous elastic member 55CI in the front-rear direction L, since the discontinuous elastic member 55N does not continuously extend in the width direction W, there is a low shrinkage region LER in which the contraction force in the width direction W is low. .. As a result, the inside of the inner continuous elastic member 55CI in the front-rear direction L is relatively easy to separate from the body side. From the above, it is possible to suppress the leakage of excrement diffused on the absorber 30 toward the front waist circumference region S1 side.

Further, the inner continuous elastic member 55CI may be composed of a plurality of elastic members adjacent to each other in the front-rear direction L. As a result, the standing portion 82 can be brought into close contact with the body in a planar manner, and the standing portion 82 can be firmly fixed at the position SP where the standing portion 82, the inner continuous elastic member, and 55CI overlap. Therefore, it is possible to prevent the excrement from reaching the outside of the upright portion 82 in the front-rear direction L. As a result, it is possible to suppress the diffusion of excrement in the width direction W from the outside of the upright portion 82 in the front-rear direction L.

Further, among the waist elastic members 55, the contraction force of the inner continuous elastic member 55CI may be the largest. By increasing the contraction force of the inner continuous elastic member 55CI, the standing portion 82 can be brought into close contact with the body. As a result, it is possible to suppress the diffusion of excrement in the width direction W from the outside of the upright portion 82 in the front-rear direction L. In addition, by bringing the standing portion 82 into close contact with the body, the inner portion in the front-rear direction L is more easily separated from the body side than the overlapping position SP of the standing portion 82 and the inner continuous elastic member 55CI. As a result, the standing portion 82 can be easily raised with the overlapping position SP as a base point, and the excrement diffused in the width direction W on the absorber 30 can be blocked.

Further, among the waist elastic members 55, the contraction force of the innermost continuous elastic member 55CIA may be the largest. The innermost continuous elastic member 55CIA can be firmly brought into close contact with the body, and excrement can be prevented from reaching the outside of the innermost continuous elastic member 55CIA in the front-rear direction L. In addition, since the standing portion 82 stands up from the position SP where the standing portion 82 and the innermost continuous elastic member 55CIA overlap, the standing portion 82 stands up by maximizing the contraction force of the innermost continuous elastic member 55CIA. It becomes easy to make the excrement, and the excrement diffused in the width direction on the absorber 30 can be blocked.

Further, the inner continuous elastic member 55CI may overlap with the low basis weight region LR in the thickness direction. As a result, the rigidity of the low basis weight region LR is lower than that of the surroundings, so that the contraction force of the inner continuous elastic member 55CI is less likely to be hindered by the rigidity of the absorber 30. In particular, since the absorption material in the low basis weight region LR has a lower basis weight than the surroundings, even if the absorber 30 absorbs excrement, the absorber 30 in the low basis weight region LR is relatively difficult to swell. In particular, in the present embodiment, since the basis weight of the low basis weight region LR is 0, the swelling of excrement can be suppressed. Therefore, the contraction of the overlapping continuous elastic member 55CO is unlikely to be inhibited even after excretion. Therefore, due to the contraction of the inner continuous elastic member 55CI, the region overlapping the inner continuous elastic member 55CI in the thickness direction T can be further brought closer to the wearer's body side. Therefore, it is possible to prevent the excrement from reaching the outside of the inner continuous elastic member 55CI in the front-rear direction L. In addition, the standing portion 82 can be easily raised, and the excrement diffused in the width direction W on the absorber 30 can be blocked.

Further, the absorption core 31, the upright portion 82, and the inner continuous elastic member 55CI may overlap in the thickness direction T. As a result, the standing portion 82 is brought into close contact with the body side due to the contraction of the inner continuous elastic member 55CI. Therefore, the position SP is based on the position SP where the standing portion 82 and the inner continuous elastic member 55CI overlap in the thickness direction T. The inner standing portion 82 stands up in the front-rear direction L. Since a part of the upright portion 82, which is the base point of the upright portion of the leg side gather 80, is supported by the highly rigid absorption core 31, the position of a part of the upright portion 82 can be stably fixed. Therefore, it is possible to make the inner standing portion 82 stand up more easily in the front-rear direction L than a part of the standing portion 82.

Further, the squeezed portion, the upright portion, and the inner continuous elastic member 55CI may overlap in the thickness direction T. As a result, a part of the upright portion 82, which is the base point for the upright portion of the leg side gather 80, is supported by the highly rigid pressing portion in the absorption core 31, so that the position of a part of the upright portion 82 is stably fixed. it can. Therefore, the inner standing portion 82 can be made easier to stand in the front-rear direction + than a part of the standing portion 82.

Further, the inner edge 811S of the front-rear fixing portion 811 may be arranged in the low shrinkage region LER. As a result, in the low shrinkage region LER, since the shrinkage force in the width direction W is low, the absorption core 31 is difficult to shrink in the width direction W, and the front-rear fixing portion 811 is hard to move inward in the width direction W. As a result, it is possible to secure a storage space for excrement in the width direction W, and it is possible to suppress the diffusion of excrement beyond the standing portion 82.

Further, the inner continuous elastic member 55CI may be arranged 5% to 20% behind the front end edge 16F of the side joint portion 16 with respect to the total length of the absorbent article 1 in the front-rear direction L in the front waist circumference region S1. As a result, the inner continuous elastic member 55CI can be provided in the region where the dent at the lower end of the wearer's abdomen is likely to be arranged. Since the dent at the lower end of the abdomen of the wearer tends to generate a gap between the wearer and the front exterior body 50A, the absorption core 31 may be easily bent in the front-rear direction L along the dent at the lower end of the abdomen of the wearer. it can. Therefore, due to the contraction of the inner continuous elastic member 55CI, the region where the inner continuous elastic member 55CI is arranged comes into close contact with the wearer's body (specifically, the recess at the lower end of the abdomen). As a result, it is possible to prevent the excrement from reaching the outside of the upright portion 82 in the front-rear direction L. On the other hand, inside the inner continuous elastic member 55CI in the front-rear direction L, the absorption core 31 is relatively easily separated from the body side due to the bending in the front-rear direction. As a result, the standing portion 82 can stand up from the vicinity of the recess at the lower end of the abdomen, so that the excrement diffused in the width direction W on the absorber 30 can be blocked.

The contraction force of the inner continuous elastic member 55CI that overlaps the leg side elastic member 85 in the thickness direction T may be larger than the contraction force of the leg side elastic member 85. As a result, the leg side elastic member 85 can be firmly fixed at a position where the leg side elastic member 85 overlaps the inner continuous elastic member 55CI in the thickness direction T. The standing portion 82 can be firmly erected by the contraction force of the leg side elastic member 85.

The telescopic sheet 55CS as the continuous elastic member 55C may be arranged inside the front-rear direction L with respect to the inner end edge 811E of the front-rear fixing portion 811. Therefore, in the front-rear direction L, the inside of the front-rear direction L of the telescopic sheet 55CS. The edge may be inside the inner edge 811E of the front-rear fixing portion 811. As a result, the standing portion 82 can stand up from the inner edge of the telescopic sheet 55CS in the front-rear direction L, so that the excrement diffused in the width direction W on the absorber 30 can be blocked. In the region where the elastic sheet 55CS and the thread-like or string-like overlapping continuous elastic member 55CO overlap in the thickness direction T, the standing portion 82 can be brought into close contact with the body, so that the excrement is L in the anterior-posterior direction than the standing portion 82. It can be prevented from reaching the outside of.

As a result, the leg elastic member 75 is easily fixed in both the front waist circumference area S1 and the rear waist circumference region S2. Therefore, the inseam area S3 can be pulled up to both the front waist area S1 and the rear waist area S2 by the contraction of the leg elastic member 75, and lateral leakage of excrement due to the hanging of the inseam area S3 is suppressed especially in the standing posture. It can be done easily.

In the absorbent article 1 according to the second modification, the inner continuous elastic member 55CI may be composed of the absorption core 31 and all the continuous elastic members 55C overlapping in the thickness direction T. That is, all the overlapping continuous elastic members 55CO may be arranged inside the front-rear direction L with respect to the inner end edge 811E of the front-rear fixing portion 811 in the front-rear direction L. As a result, the absorption core 31 can be brought into close contact with the wearer's body due to the contraction of the inner continuous elastic member 55CI, and the excrement can be prevented from reaching the outside of the absorption core 31 in the front-rear direction L. In addition, since the inner continuous elastic member 55CI is arranged inside the front-rear direction L with respect to the inner end edge 811E of the front-rear fixing portion 811, the excrement reaches the outside of the front-rear direction L with respect to the standing portion 82. That can be further prevented. As a result, it is possible to suppress the diffusion of excrement in the width direction W from the outside of the upright portion 82 in the front-rear direction L.
