In the absorbent articles described in Patent Document 1 and Patent Document 2, the inner side in the width direction of the three-dimensional gather is configured to be able to bulge to the skin side. Specifically, since the inner tip in the width direction of the three-dimensional gather stands up with the outer side in the width direction of the three-dimensional gather as a fulcrum (see FIG. 2 of Patent Document 1 and FIG. 2 of Patent Document 2), the three-dimensional gather when worn The slope of the is opposite to the slope of the wearer's skin. Therefore, only the inner tip in the width direction of the three-dimensional gather comes into contact with the skin of the wearer, which causes concern about leakage of body fluid.

In the absorbent article described in Patent Document 2, the colored figure is provided near the center of the absorbent article in the front-rear direction. However, a person who causes the wearer to wear the absorbent article, for example, a wearer such as a caregiver, has difficulty in understanding which position on the wearer's body the colored figure should be adjusted to, depending on the body shape of the wearer.

Further, the colored figure is provided at a position overlapping with the elastic member for forming the leg gathers. Therefore, the region where the colored figure is provided is contracted in the front-rear direction, which makes it difficult to visually recognize the worn figure. In this case, the mounting assistant does not stabilize the position of the colored figure, and it is difficult to use the colored figure as a positioning mark.

Therefore, there is a demand for an absorbent article having a mark that can improve a sense of security against leakage of bodily fluid and that is easier for a wearer to understand and can be easily positioned with respect to the wearer.

The absorbent article according to one aspect has a front-rear direction, a width direction orthogonal to the front-rear direction, a front waist region, a rear waist region, a front waist region, and a back waist region. A crotch region, an absorber provided in at least the crotch region and the rear waist region, fastening tapes provided on both widthwise outer sides of the rear waist region, and at least the front and rear portions in the crotch region. And a gather provided on the skin surface side. The gather includes a gather sheet configured such that an outer side portion in the width direction can be erected, and a plurality of elastic members provided on the gather sheet and extending along the front-rear direction. At least one first elastic member of the plurality of elastic members or an imaginary line obtained by extending the first elastic member in the front-rear direction overlaps the absorber in the rear waist region. The first elastic member has a contracting portion that contracts in the front-rear direction together with the gather sheet. The rear edge of the shrinking portion is located rearward of the center of the absorbent article in the front-rear direction and in front of the line connecting the front edges of the fastening tape. Of the plurality of elastic members, the second elastic member positioned on the outermost side in the width direction of the gather sheet extends rearward from the rear edge of the contracting portion.

It is possible to provide an absorbent article having a mark that can improve the sense of security against leakage of body fluid, can be more easily understood, and can be easily positioned by the wearer.

(1) Outline of Embodiments At least the following matters will be made clear by the present specification and the description of the accompanying drawings.

The absorbent article according to one aspect has a front-rear direction, a width direction orthogonal to the front-rear direction, a front waist region, a rear waist region, a front waist region, and a back waist region. A crotch region, an absorber provided in at least the crotch region and the rear waist region, fastening tapes provided on both widthwise outer sides of the rear waist region, and at least the front and rear portions in the crotch region. Direction, and has a gather provided on the skin surface side, and the gather has a gather sheet configured such that an outer side portion in the width direction is erected, and the gather sheet is provided in the gather sheet, and the gather sheet is provided in the front-rear direction. A plurality of elastic members extending along the at least one first elastic member of the plurality of elastic members, or an imaginary line obtained by extending the first elastic member in the front-rear direction is the rear waistline. In a region, the first elastic member overlaps with the absorber, and the first elastic member has a contracting part that contracts in the front-rear direction together with the gather sheet, and a rear edge of the contracting part is the absorbent article of the absorbent article. A second elastic member that is located rearward of the center in the front-rear direction and is located in front of a line that connects the front edges of the fastening tape, and is located on the outermost side in the width direction of the gather sheet among the plurality of elastic members. The member extends rearward from the rear edge of the contracting portion.

In the absorbent article according to this aspect, the gather has the gather sheet configured such that the outer side portion in the width direction can be erected, and the gather comes into close contact with the wearer's skin when worn. In particular, since the widthwise outer portion of the gather sheet is configured to be able to stand up, the slope of the gathered sheet that has stood up is approximately along the slope of the wearer's skin, and the skin side of the gather sheet is a surface of the wearer. Fits the skin. As a result, it is possible to give a sense of security that the liquid can be prevented from leaking at least in the crotch region.

Further, since the second elastic member extends rearward of the rear edge of the contracting portion, the outermost tip in the width direction of the gather sheet is located at the rear side of the contracting portion of the first elastic member. 2 It rises slightly to the skin side due to the contraction action of the elastic member. Thereby, even if urine is transmitted to the back side in a sleeping posture of the wearer, it is possible to prevent the liquid from leaking from the outer side in the width direction of the rear waist region.

Further, the first elastic member forming the gather can be used as a mark for wearing the absorbent article at an appropriate position. Specifically, the mounting assistant first changes the state in which the wearer is lying on his back to the state in which the wearer is lying sideways. The wearing assistant lays the absorbent article under the buttocks of the wearer so that the center of the absorbent article and the center of the body are aligned with the wearer lying sideways. At this time, the wearing assistant collects the first region on the side where the body is lower than the center of the absorbent article in the width direction, moves the first region near the lower side of the body, and opposes the first region. The second area on the side is spread. Here, since the first elastic member or a virtual line extending the first elastic member in the front-rear direction overlaps with the absorber in the rear waistline region, a guideline for the position of the outer end portion of the absorber in the width direction. Becomes Therefore, it becomes easy for the wearing assistant to understand at which position in the width direction the absorbent article should be placed under the buttocks of the wearer lying sideways, using the first elastic member as a guide.

Furthermore, the rear edge of the contracting portion of the first elastic member is located rearward of the center of the absorbent article in the front-rear direction and in front of the line connecting the front edges of the fastening tape. This position roughly corresponds to the cracked portion of the base of the wearer's leg, that is, the lower end of the groin. Therefore, by aligning the rear edge of the contracting portion of the first elastic member with the cracked portion of the base of the wearer's leg, the position of the absorbent article in the front-rear direction can be aligned. Here, since the colored pattern as in Patent Document 2 is provided at the center of the absorbent article in the front-rear direction and where it is contracted by the contraction portion, it is difficult for the wearer to visually recognize it due to the contraction of the sheet, It may be difficult to know where to position the colored figure on the wearer. On the other hand, in this aspect, since the end of the contracted portion, that is, the boundary between the contracted portion and the non-contracted portion can be used as the mark, the mark does not become difficult to be visually recognized due to the contraction of the sheet accompanying the contraction of the elastic member. Also, as described above, the absorbent article can be positioned in the front-rear direction by aligning the rear edge of the contraction portion with the cracked portion of the base of the wearer's leg.

Next, the mounting assistant changes the position of the wearer to the back so that the wearer's body is placed on the second area. Next, the mounting assistant changes the position of the wearer from the supine position to the opposite lateral position, and pulls the first region outward from the bottom of the wearer's body in the width direction. At this time, the position of the absorbent article with respect to the wearer may be finely corrected by using the end portion of the contracted portion of the first elastic member as a mark.

Next, the mounting assistant changes the position of the wearer to the back again, covers the abdomen of the mounting assistant with the front waist region, and fastens the fastening tape provided on the rear waist region to the front waist region. ..

As described above, in the absorbent article according to the present aspect, the first elastic member used as a gather and the end of the contracted portion can be used as a mark when the absorbent article is positively worn. Therefore, it is a mark that is easier for the wearer to understand and easier to position for the wearer.

According to a preferred embodiment, the back waist region is a skin sheet provided on the skin side of the absorber, a non-skin sheet provided on the non-skin side of the absorber, and the skin surface. A sheet and a flap sheet that extends outward in the width direction with respect to the non-skin surface sheet, the flap sheet including the fastening tape, the rear edge of the shrinking portion, the front edge of the flap sheet to each other. It is located in front of the connecting line.

Since the contraction portion of the first elastic member is located in front of the line connecting the front edges of the flap sheet, it is possible to prevent the flap sheet from contracting in the front-rear direction. As a result, the shape in the vicinity of the region where the fastening tape is provided is stable, so that the fastening tape can be stably fixed to the front waist region.

According to a preferred aspect, the gather sheet has a fixing portion fixed to a sheet on the non-skin side of the gather sheet on the rear side of the rear edge of the contracting portion.

Since the gather sheet is fixed to the gather sheet at the rear side of the rear side edge of the contracting section, the rigidity of the rear side region becomes higher than the rear side edge of the contracting section, and the rear side of the contracting section becomes higher. The shape of the area behind the edge is stable. The area on the rear side of the rear edge of the shrinking portion is closer to the area where the fastening tape is provided. Since the shape near the region where the fastening tape is provided is stable, the fastening tape can be stably attached to the front waist region.

According to a preferred aspect, the fixing portion extends in the front-rear direction across a line connecting front edges of the fastening tape. As a result, it is possible to increase the rigidity of the region from the position in front of the line connecting the front edges of the fastening tape to the position in the rear of the line. Therefore, the shape of the region on the line connecting the fastening tapes is more stable, and the fastening tape can be stably fixed to the front waist region.

According to a preferred aspect, the absorbent body has a plurality of low basis weight regions each of which is formed of an absorbent material having a basis weight lower than that of the surrounding absorbent material or a region where the absorbent material does not exist, and the plurality of low basis weight regions. Are extending along the front-rear direction, are arranged at intervals in the width direction, the end in the front-rear direction of the low basis weight region is more than the center in the front-rear direction of the absorbent article. It is located on the rear side and in front of the line connecting the front edges of the fastening tape.

The low basis weight area of the absorbent body can be visually recognized from the skin side of the absorbent article or can be recognized by touching. Therefore, the mounting assistant visually or tactilely senses that the end portion in the front-rear direction of the low basis weight area is located behind the center in the front-rear direction of the absorbent article and in front of the line connecting the front edges of the fastening tape. Can be recognized as being located. Since the position of the end portion of the low basis weight region in the front-rear direction is approximately the same as the position of the end portion of the contraction portion in the front-rear direction, it can be used as a guide for the position of the end portion of the contraction portion as a mark.

In particular, when the low basis weight area is visible from the skin surface side of the absorbent article, the boundary between the low basis weight area of the absorbent body and the area around the absorbent body, that is, the end of the low basis weight area should be seen by the wearer's eyes. Easy to pull. Here, since the plurality of low basis weight regions are lined up in the width direction at intervals, the eyes of the wearing assistant easily move in the width direction. The position of the end portion of the low basis weight region in the front-rear direction is substantially the same as the position of the end portion of the contraction portion in the front-rear direction, and therefore, the mounting assistant uses the end portion of the contraction portion of the first elastic member, That is, it becomes easy to recognize the mark for wearing the absorbent article at an appropriate position.

According to a preferred aspect, the first elastic member is provided on the rear side of the contracting portion and adjacent to the contracting portion, and has an end portion in a natural state that is wider than the contracting portion in the width direction.

Since the natural end of the first elastic member is wide in the width direction, the natural end is easy to visually recognize. Since the end portion in the natural state is provided adjacent to the contracting portion, the end portion of the contracting portion, that is, the mark for wearing the absorbent article at an appropriate position can be conspicuous.

According to a preferred aspect, the end portion in the natural state is located in front of a line connecting front edges of the fastening tape. As a result, the natural end of the first elastic member approximately corresponds to the cracked portion of the base of the wearer's leg, that is, the lower end of the groin. Therefore, not only the rear end of the contracting portion of the first elastic member but also the natural end of the first elastic member can be used as a mark for aligning the absorbent article in the front-rear direction.

According to a preferred aspect, the absorbent article has a fold line extending along the front-rear direction, and the fold line is formed in a region different from the region in which the plurality of elastic members are provided.

Since the fold line extending along the front-rear direction is formed in a region different from the region in which the plurality of elastic members are provided, it is possible to suppress the formation of a crease in the region in which the plurality of elastic members are provided. .. This makes it easier to bring the gathers, which are composed of a plurality of elastic members, into close contact with the wearer's skin.

According to a preferred aspect, a rear waistline elastic member along the width direction is provided in the rear waistline region, and the first elastic member is more than the rear waistline elastic member in the width direction. Located on the outside.

Since the first elastic member is located outside the rear waistline elastic member in the width direction, it is possible to reduce the risk that the position of the end of the contracted portion of the first elastic member is displaced due to the contraction of the rear waistline elastic member. can do. This makes it easier to cause the end of the contracting portion of the first elastic member to function as a mark.

An absorbent pad according to one aspect is an absorbent pad used in the absorbent article described above, wherein the front-rear direction along the front-rear direction of the absorbent article, a width direction orthogonal to the front-rear direction, and the width A maximum width portion having a maximum width in a direction, and a constricted portion constricted in the width direction from the maximum width portion, wherein the boundary between the maximum width portion and the constricted portion is the absorbent at the time of use. It is located behind the center of the article in the front-rear direction and in front of the line connecting the front edges of the fastening tape.

Both the boundary between the maximum width portion and the constricted portion of the absorbent pad and the rear end of the contracting portion of the first elastic member of the absorbent article are rearward of the center in the front-rear direction of the absorbent article. It is located in front of the line that connects the front edges of the tape. Therefore, the rear end of the contracting portion of the first elastic member of the absorbent article can also be used as a mark when attaching the absorbent pad to the absorbent article. Specifically, the absorbent pad is attached to the absorbent article so that the boundary between the maximum width portion and the constricted portion of the absorbent pad is located at the rear end of the contracted portion of the first elastic member of the absorbent article. Thus, the absorbent pad can be attached to an appropriate position on the absorbent article.

FIG. 1 is a diagram showing a state in which the absorbent article is stretched to a state in which the wrinkles of the sheet constituting the absorbent article 100 are eliminated. FIG. 2 is a cross-sectional view of the absorbent article taken along the line AA of FIG.

The absorbent article according to the present embodiment is preferably of a type that a wearer such as a caregiver wears on a wearer such as a care recipient. In particular, the absorbent article according to the present embodiment is preferably a disposable diaper for adults.

The absorbent article 1 includes a front-back direction L extending to the front side and a back side of the wearer's body, a width direction W orthogonal to the front-back direction L, and a thickness direction T orthogonal to the front-back direction L and the width direction W. Have. Further, in the present specification, the “skin surface side” corresponds to the side facing the wearer's skin during use. The "non-skin side" corresponds to the side facing away from the wearer's skin during use.

The absorbent article 100 has a front waist region R1, a back waist region R2, and a crotch region R3. The front waist region R1 faces the front side of the wearer's body during use. The rear waist region R2 faces the rear side of the wearer's body during use. The crotch region R3 is located between the front waistline region R1 and the rear waistline region R2, and is disposed at the crotch of the wearer during use.

The absorbent article 100 has at least the absorber 40 arranged in the crotch region R3 and the rear waist region R2. The absorber 40 may extend from the crotch region R3 to the front waist region R1 and the back waist region R2.

The absorbent article 100 includes the skin sheet 10 provided on the skin surface side of the absorber 40 and the non-skin surface sheet 20 provided on the non-skin surface side of the absorber 40. The skin sheet 10 covers the absorber 40. The skin sheet 10 may include at least one layer of liquid-permeable sheet. The non-skin surface sheet 20 may include at least one layer of a liquid-impermeable sheet.

The absorbent article 100 has the fastening tapes 94 provided on both outer sides of the rear waistline region R2 in the width direction W. Two fastening tapes 94 may be provided on both outer side portions in the width direction W. In this case, the pair of fastening tapes 94 located on the rear side tightens the circumference of the wearer's waist, and the pair of fastening tapes 94 positioned on the front side lowers the circumference of the wearer's waist, for example, around the legs. You can tighten the vicinity. The fastening tape 94 has an engaging portion 96 that engages with the front waist region R1. The engagement part 96 may be configured by a large number of hooks. In this case, the front waist region R1 may have a loop region 98 that can be engaged with the engaging portion 96.

As a specific example, the fastening tape 94 may be formed on the flap sheet 90. The flap sheet 90 extends outward in the width direction W with respect to the skin surface sheet 10 and the non-skin surface sheet 20. The flap sheet 90 may be joined to the skin sheet 10 and/or the non-skin sheet 20 at the joint portion 92. From the viewpoint of increasing the joining force of the flap sheet 90, the skin sheet 10 and/or the non-skin sheet 20 may be joined to both the skin sheet 10 and the non-skin sheet 20.

The absorbent article 100 has gathers that extend in the front-rear direction L at least in the crotch region R3 and are provided on the skin surface side. In the present embodiment, the gather includes an inward gather 50 in which the inner portion in the width direction W can stand and an outward gather 60 in which the outer portion in the width direction W can stand.

The inward gather 50 may include the skin sheet 10 and the inner elastic member 52. Specifically, the outer side portion of the skin sheet 10 is folded back inward in the width direction W. The inner elastic member 52 is wrapped by the folded-back portion of the outer portion of the skin sheet 10. The inner elastic member 52 constitutes a gather together with the outer portion of the skin sheet 10 by being attached to the outer portion of the skin sheet 10 in a stretched state.

The outward gather 60 includes a gather sheet 61 whose outer portion in the width direction W can be erected and a plurality of elastic members extending along the front-rear direction L. The plurality of elastic members include a first elastic member 62 and a second elastic member 66. The first elastic member 62 and the second elastic member 66 are provided on the gather sheet 61. The first elastic member 62 and the second elastic member 66 form an outward gather 60 together with the gather sheet 61 by being attached to the gather sheet 61 in a stretched state.

The first elastic member 62 is provided inside the second elastic member 66 in the width direction W. A plurality of the first elastic members 62 may be provided at intervals in the width direction. The second elastic member 66 is located on the outermost side in the width direction W of the gather sheet 61 among the plurality of elastic members.

In the absorbent article according to this aspect, the outward gather 60 has a gather sheet 61 whose outer portion in the width direction W can be erected, and the gather sheet 61 is in close contact with the wearer's skin when worn. .. In particular, since the outer side portion of the gather sheet 61 in the width direction is configured to be erected, the slope of the erected gather sheet 61 substantially follows the inclination of the wearer's skin and fits the wearer's skin in a planar manner. .. As a result, it is possible to give a sense of security that the leakage of the liquid can be prevented.

The gather sheet 61 is preferably made of a hydrophobic non-woven fabric. This can prevent the liquid from seeping out through the gather sheet 61.

The first elastic member 62 or an imaginary line obtained by extending the first elastic member 62 in the front-rear direction L overlaps with the absorber 40 in the rear waistline region R2. The first elastic member 62 has a contraction portion 63 that contracts in the front-rear direction L together with the gather sheet 61. The rear edge of the contracting portion 63 of the first elastic member 62 is located behind the center CL of the absorbent article 100 in the front-rear direction L and in front of the line L1 connecting the front edges of the fastening tape 96. .. Thereby, as will be described later, the first elastic member 62 and the rear end of the contracting portion 63 can be used as a mark when the absorbent article 100 is worn.

In order to make the rear end portion of the first elastic member 62 and the contracting portion 63 thereof conspicuous, it is preferable that the first elastic member 62 be formed in a color different from that of the gather sheet 61. As a specific example, the gather sheet 61 is white and the first elastic member 62 is blue or light blue.

The first elastic member 62 may be provided on the rear side of the contracting portion 63 and adjacent to the contracting portion 63, and may have an end portion 64 in a natural state that is wider in the width direction W than the 63 contracting portion. The natural end portion 64 is not joined to the gather sheet 61. Since the natural end 64 of the first elastic member 62 is widened in the width direction W, the natural end 64 is easily visible. Since the end portion 64 in this natural state is provided adjacent to the contracting portion 63, the end portion of the contracting portion 63, that is, the mark for wearing the absorbent article 100 at an appropriate position can be made conspicuous. .. When not only the end of the first elastic member 62 on the rear side of the contracting portion 63 but also the end 64 of the first elastic member 62 in the natural state is used as a mark, the end 64 in the natural state is the fastening tape 94. It is preferable to be located in front of the line L1 connecting the front edges of the.

The rear edge of the contracting portion 63 of the first elastic member 62 is preferably positioned in front of the line L2 that connects the front edges of the flap sheet 90. Accordingly, it is possible to prevent the flap sheet 90 from contracting in the front-rear direction L due to the contracting action of the first elastic member 62. Therefore, the shape near the region where the fastening tape 94 is provided is stable, so that the fastening tape 94 can be stably fixed to the front waist region R1.

The contraction portion 63 of the first elastic member 62 is preferably provided on the rear side of the loop region 98 of the front waist region R1. As a result, it is possible to prevent wrinkles from being generated in the loop region 98 due to the contracting action of the first elastic member 62. Therefore, the fastening tape 94 can be stably fixed to the loop region 98.

The flap sheet 90 is preferably formed with a length that covers only the circumference of the wearer's waist. If the flap sheet 90 extends to the crotch side of the wearer's waistline, the flap sheet 90 may be an obstacle and make it difficult for the wearer to wear the absorbent article. Further, the flap sheet 90 is formed to have a length that covers only the circumference of the wearer's waist, and the rear edge of the contracting portion 63 of the first elastic member 62 ties the front edges of the flap sheet 90 together. When located in front of the line L2, the rear edge of the contracting portion 63 of the first elastic member can be used as an alignment for the cracked portion of the base of the wearer's leg, that is, the lower end of the groin, and The flap sheet 90 can be used as an alignment for the wearer's waist.

The gather sheet 61 is fixed to a sheet on the non-skin surface side of the gather sheet 61 on the rear side of the rear edge of the contracting portion 63, and on the non-skin surface side of the folded gather sheet 61 in the present embodiment. It is preferable to have the fixing portion 70. In the region where the fixing portion 70 is present, the outward gather 60 is less likely to stand up than the crotch region R3 or is unable to stand up.

The fixed portion 70 increases the rigidity of the region on the rear side of the rear edge of the contracting portion 63, and stabilizes the shape of the region on the rear side of the rear edge of the contracting portion 63. The area on the rear side of the rear edge of the contracting portion 63 is close to the area where the fastening tape 94 is provided. Since the shape near the region where the fastening tape 94 is provided is stable, the fastening tape 94 can be stably fixed to the front waist region R1.

The fixed portion 70 preferably extends in the front-rear direction L across a line L1 connecting the front edges of the fastening tape 94. As a result, it is possible to increase the rigidity of the region from the position in front of the line L1 connecting the front edges of the fastening tape 94 to the position in the rear of the line L1. Therefore, the shape of the region on the line connecting the fastening tapes 94 is more stable, and the fastening tape 94 can be stably fixed to the front waist region R1.

The second elastic member 66 preferably extends rearward of the rear edge of the contracting portion 63 of the first elastic member 62. As a result, in the rear waistline region R2, the outermost tip of the gather sheet 61 in the width direction W slightly rises due to the contracting action of the second elastic member 66. Thereby, even if urine is transmitted to the back side in a sleeping posture of the wearer, it is possible to prevent the liquid from leaking from the outer side in the width direction of the rear waist region R2.

The absorbent article 100 may include the rear waistline elastic member 80 along the width direction W in the rear waistline region R2. The rear waistline elastic member 80 is attached to the seat forming the rear waistline region R2 in an expanded state. The first elastic member 62 is located outside the rear waistline elastic member 80 in the width direction W. Since the first elastic member 62 is located outside the rear waistline elastic member 80 in the width direction W, the position of the end of the contracting portion 63 of the first elastic member 62 is changed by the contraction of the rear waistline elastic member 80. The risk of displacement can be reduced. Thereby, the end of the contracting portion 63 of the first elastic member 62 can be made to easily function as a mark.

The absorbent article 100 may be folded in the packaged state. Therefore, the absorbent article 100 may have the fold line FL that extends along the front-rear direction L for folding the absorbent article 100 in the packaged state. The fold line FL may be a valley fold line when viewed from the skin surface side. Preferably, the fold line FL is formed in a region different from the region in which the plurality of elastic members 62, 66 configuring the outward gather 60 are provided. More preferably, the fold line FL is provided inside the region in which the plurality of elastic members 62 and 66 are provided in the width direction W. As a result, it is possible to prevent the region in which the plurality of elastic members 62 and 66 are provided from having a crease. Therefore, the outward gather 60 formed by the plurality of elastic members 62, 66 can be easily brought into close contact with the wearer's skin.

The absorbent body 40 may have a plurality of low basis weight areas 42 that are formed of an absorbent material having a basis weight lower than that of the surrounding absorbent material, or a region having no absorbent material. The plurality of low basis weight regions 42 extend in the front-rear direction L and are arranged in the width direction W at intervals. Preferably, the end portion of the low basis weight region 42 in the front-rear direction L is located behind the center CL of the absorbent article 100 in the front-rear direction L and in front of the line L1 connecting the front edges of the fastening tape 94. ..

The low basis weight area 42 of the absorbent body can be visually recognized from the skin side of the absorbent article or can be recognized by touching. Therefore, the wearing assistant visually or tactilely senses that the end portion of the low basis weight region 42 in the front-rear direction L is behind the center CL of the absorbent article 100 in the front-rear direction L and the front edges of the fastening tape 94. It can be recognized that it is located in front of the line L1 connecting the lines. Since the position of the end portion of the low basis weight region 42 in the front-rear direction L is approximately the same as the position of the end portion of the contraction portion 63 in the front-rear direction L, it is used as a guide for the position of the end portion of the contraction portion 63 as a mark. Can be used.

In particular, when the low basis weight area 42 is visible from the skin side of the absorbent article 100, the boundary between the low basis weight area 42 of the absorbent body and the area around it, that is, the end of the low basis weight area 42, is a mounting aid. Easy to catch Here, since the plurality of low basis weight regions 42 are arranged at intervals in the width direction W, the eyes of the wearer easily move in the width direction W. Since the position of the end portion of the low basis weight region 42 in the front-rear direction L is approximately the same as the position of the end portion of the contraction portion 63 in the front-rear direction, the mounting assistant uses the contraction portion 63 of the first elastic member 62. It becomes easy to recognize the end portion, that is, the mark for wearing the absorbent article 100 at an appropriate position.

More preferably, the end of the low basis weight region 42 in the front-rear direction L is located in front of a line L2 connecting front edges of the flap sheet 90 described later. Thereby, the end portion of the low basis weight region 42 in the front-rear direction L can be arranged at a position closer to the position of the end portion of the contraction portion 63 in the front-rear direction.

Further, the low basis weight region 42 may be composed of a region in which the absorbent material is substantially absent. In this case, since the absorbent article 100 can be positively bent at the low basis weight area 42, the absorbent article 100 is less likely to be twisted during use.

The absorber 40 may be bound in the width direction W in the crotch region R3. In other words, the width W of the absorber 40 in the crotch region R3 is smaller than the width W of the absorber 40 in the front waist region R1 and the rear waist region R2. In this case, it is preferable that the first elastic member 62 that constitutes the outward gather 60 is located outside the outer edge of the absorbent body 40 in the crotch region R3 in the width direction W. As a result, a recess is formed between the outer edge of the absorbent body 40 in the width direction W and the standing outward gather 60. Therefore, even if the body fluid flows to the outside in the width direction W along the surface of the absorber 40, the body fluid is stored in the recess. Therefore, it is possible to prevent body fluid from leaking from the outside of the crotch region R3 in the width direction W.

The mark does not become hard to see.

Next, the mounting assistant changes the position of the wearer to the back so that the wearer's body is placed on the second region 102 (see FIG. 3C). Next, the mounting assistant changes the body position of the wearer from the supine state to the opposite side-to-side state (see FIG. 3(d)), and the first region 101 from the bottom of the wearer's body to the outer side in the width direction. (See Fig. 3(e)). At this time, the position of the absorbent article 100 with respect to the wearer may be finely corrected by using the end of the contracting portion 63 of the first elastic member 62 as a mark.

Next, the wearing assistant changes the body position of the wearer to the supine state again (see FIG. 3(f)), covers the abdomen of the wearing assistant with the front waist region R1, and is provided in the back waist region R2. The fastening tape 94 is fastened to the front waist region R1. This allows the wearer to wear the absorbent article 100 on the wearer.

As described above, in the absorbent article 100 according to this aspect, when the absorbent article 100 is positively worn, the first elastic member 62 used as the outward gather 60 and the end portion of the contracting portion 63 thereof are worn. Since it can be used as a mark, it is a mark that can be more easily understood by the wearing assistant and can be easily positioned with respect to the wearer.

Here, as described above, when the natural end portion 64 of the first elastic member 62 is located in front of the line L1 connecting the front edges of the fastening tape 94, the natural end portion of the first elastic member 62 is used. The portion 64 generally corresponds to the cracked portion of the base of the wearer's leg, that is, the lower end of the groin. Therefore, not only the rear end of the contraction portion of the first elastic member 62 but also the natural end 64 of the first elastic member is used as a mark for aligning the absorbent article 100 in the front-rear direction L. be able to. When the natural state end portion 64 of the first elastic member 62 is also used as a mark, the natural state end portion 64 of the first elastic member 62 must be located in front of the line L2 connecting the front edges of the flap sheet 90.
