At least the following matters will be made clear from the description of the present specification and the drawings.

An absorbent article according to one aspect has: a front-back direction and a width direction orthogonal to each other; a crotch region including the center in the front-rear direction, a front waistline region located on the front side of the crotch region, and a rear waistline region located on the rear side of the crotch region; an absorbent core disposed in at least the crotch region; a fixing member protruding outward in the width direction in the rear waistline region; and a target region in the front waistline region to which the fixing member is fixed, the fixing member having: a 1 st flap having a 1 st engaging portion fixed to the target region; and a 2 nd wing piece which is positioned on the front side of the 1 st wing piece and has a 2 nd engaging portion fixed to the target area, wherein the target area is provided with a 1 st mark portion and a 2 nd mark portion positioned on the rear side of the 1 st mark portion, and the 1 st mark portion includes: a 1 st outer end pattern similar to a 1 st outer end located at the widthwise outer end of the 1 st flap in a developed state of the absorbent article; and a 1 st cross pattern similar to a 1 st cross edge, the 1 st cross edge crossing the 1 st outer edge of the 1 st tab and extending in the width direction, the 2 nd mark portion having: a 2 nd outer end pattern similar to a 2 nd outer end located at the widthwise outer end of the 2 nd flap in the unfolded state; and a 2 nd intersecting pattern similar to a 2 nd intersecting edge, the 2 nd intersecting edge intersecting with the 2 nd outer end edge of the 2 nd fin and extending in the width direction, the 1 st mark portion and the 2 nd mark portion being arranged in line in the front-rear direction.

The 1 st tab is a pattern similar to the intersecting two sides of the 1 st tab (the 1 st outer edge and the 1 st intersecting edge), and the 2 nd tab is a pattern similar to the intersecting two sides of the 2 nd tab (the 2 nd outer edge and the 2 nd intersecting edge). The wearer can appropriately grasp the position where the 1 st flap is aligned with the 1 st mark and the position where the 2 nd flap is aligned with the 2 nd mark, as compared with the mark formed by a single line. Further, since the 1 st tab and the 2 nd tab are arranged in the front-rear direction, the positions at which the 1 st flap and the 2 nd flap arranged in the front-rear direction are fixed are not easily confused. Whereby the respective fin can be fixed in position.

According to a preferable aspect, the 1 st cross pattern and the 2 nd cross pattern may extend so as to approach each other in the front-rear direction as going toward the inner side in the width direction. According to this aspect, the 1 st flap and the 2 nd flap can be fixed so as to approach each other as they face inward in the width direction. The angle of the 1 st flap and the angle of the 2 nd flap can also be guided, so that the fixing member can be fixed in a manner that the force of fastening with respect to the center of the width direction of the abdomen of the wearer is increased.

According to a preferred aspect, the 1 st mark part and the 2 nd mark part may be separated in the front-rear direction. According to this aspect, the positions at which the 1 st fin and the 2 nd fin arranged in the front-rear direction are fixed can be more easily distinguished, and the respective fins can be fixed at appropriate positions.

According to a preferred aspect, at least one of the 1 st mark part and the 2 nd mark part may be disposed in a region overlapping with the absorbent core. According to the present aspect, the absorbent core can be pressed by fixing at least one of the 1 st flap and the 2 nd flap. The adhesiveness of the absorbent core can be improved, and leakage can be suppressed.

According to a preferred aspect, at least one of the 1 st and 2 nd marked portions may span the front end edge of the absorbent core. According to this aspect, the front end edge of the absorbent core can be pressed by fixing at least one of the 1 st flap and the 2 nd flap. The adhesive property of the absorbent core can be improved, and leakage caused by the front edge of the absorbent core hanging from the body can be suppressed.

According to a preferable aspect, the front end edge of the absorbent core may extend rearward toward the inside in the width direction, and the 1 st cross pattern may extend rearward toward the inside in the width direction. According to this aspect, the absorbent core can be pressed along the shape of the front end edge of the absorbent core by fixing the 1 st flap along the 1 st cross pattern of the 1 st mark portion. Leakage due to the front end edge of the absorbent core hanging from the body can be suppressed.

According to a preferred aspect, the 1 st mark portion may have a 1 st engagement pattern similar to the 1 st engagement portion, and the 2 nd mark portion may have a 2 nd engagement pattern similar to the 2 nd engagement portion. According to this aspect, the position of the 1 st engaging portion can be directly aligned with the 1 st engaging pattern, and the position of the 2 nd engaging portion can be directly aligned with the 2 nd engaging pattern. Thereby enabling the individual fins to be fixed in more appropriate positions.

According to a preferred embodiment, the 1 st mark portion includes an outer 1 st mark portion and an inner 1 st mark portion disposed at a position inward in the width direction from the outer 1 st mark portion, the 2 nd mark portion includes an outer 2 nd mark portion and an inner 2 nd mark portion disposed at a position inward in the width direction from the outer 2 nd mark portion, the outer 1 st mark portion includes a 1 st recognized portion having a color difference Δ E with respect to the inner 1 st mark portion of 3.0 or more, and the outer 2 nd mark portion includes a 2 nd recognized portion having a color difference Δ E with respect to the inner 2 nd mark portion of 3.0 or more. The wearer can select the outer 1 st marker and the inner 1 st marker, and can select the outer 2 nd marker and the inner 2 nd marker, depending on the body size of the wearer, etc. In this case, the wearer can easily distinguish the outer 1 st mark from the inner 1 st mark by the 1 st identification part, and can easily distinguish the outer 2 nd mark from the inner 2 nd mark by the 2 nd identification part. Therefore, the 1 st flap can be fixed at a position suitable for the body shape of the wearer without confusing the outer 1 st tab and the inner 1 st tab, and the 2 nd flap can be fixed at a position suitable for the body shape of the wearer without confusing the outer 2 nd tab and the inner 2 nd tab.

According to a preferred aspect, the 1 st outer end pattern may have a length longer than the 1 st outer end edge, the 1 st cross pattern may have a length longer than the 1 st cross edge, the 2 nd outer end pattern may have a length longer than the 2 nd outer end edge, and the 2 nd cross pattern may have a length longer than the 2 nd cross edge. The 1 st tab is not entirely covered by the 1 st tab in a state where the 1 st tab is aligned with the 1 st mark, and the 2 nd tab is not entirely covered by the 1 st tab in a state where the 2 nd tab is aligned with the 2 nd mark. Therefore, the 1 st and 2 nd markers can be visually recognized with the 1 st and 2 nd fins fixed, and whether the fin fixing position is appropriate can be determined. The fastening position of the wings can be corrected as desired so that the respective wings are fastened in place.

(2) Embodiments of absorbent article

A disposable diaper as an absorbent article of an embodiment is described below with reference to the drawings. The disposable diaper may be a disposable diaper for adults or a disposable diaper for children. In the following description of the drawings, the same or similar parts are denoted by the same or similar reference numerals. However, the drawings are schematic, and it should be noted that the scale of each dimension and the like are different from the actual scale and the like. Therefore, specific dimensions and the like should be determined with reference to the following description. Further, the drawings may include portions having different dimensional relationships and ratios from each other.

Fig. 1 is a plan view of the absorbent article 10 according to the present embodiment as viewed from the skin surface side, and fig. 2 is a plan view of the absorbent core 30 according to the embodiment as viewed from the skin surface side. Fig. 3 isbase:Sub>A sectional view taken along linebase:Sub>A-base:Sub>A shown in fig. 1. The plan views shown in fig. 1 and 2 show an extended state in which the absorbent article 10 is extended to a state in which no gathers are formed. The absorbent article 10 of the present embodiment is an extended type absorbent article for adults, but is not limited to this. The absorbent article 10 may also be an absorbent article for children.

The absorbent article 10 has a front-back direction L and a width direction W that are orthogonal to each other. The front-back direction L is defined by a direction extending to the body front side and the body rear side. In other words, the front-rear direction L is a direction extending in the front-rear direction in the unfolded absorbent article 10. The absorbent article 10 has a thickness direction T orthogonal to both the front-back direction L and the width direction W. The thickness direction T extends toward the skin surface side T1 on the wearer side and toward the non-skin surface side T2 on the wearer side. In the present specification, the "skin surface side" corresponds to a side facing the skin of a wearer during use. The "non-skin-side" corresponds to a side facing away from the skin of the wearer during use.

The absorbent article 10 has a front waistline region S1, a rear waistline region S2, and a crotch region S3. The front waistline region S1 faces the body front side of the wearer in use. The rear waist region S2 faces the rear side of the wearer' S body in use. The crotch region S3 is located between the front waistline region S1 and the rear waistline region S2, and is disposed in the crotch of the wearer during use. The crotch region S3 can be defined by the absorbent core 30. Specifically, in the absorbent core 30 having the constriction 31, the region of the absorbent core 30 in which the constriction 31 is formed is the region of the crotch region S3 in the front-rear direction L. In the absorbent core 30 without the constriction 31, the central region of the region obtained by trisecting the length of the absorbent core 30 in the front-rear direction is the region in the front-rear direction L of the crotch region S3. In the present embodiment, the front end edge of the narrowing portion 31 of the absorbent core 30 defines the boundary between the crotch region S3 and the front waistline region S1, and the rear end edge of the narrowing portion 31 of the absorbent core defines the boundary between the crotch region S3 and the rear waistline region S2.

The absorbent article 10 has leg hole openings 65. The leg hole openings 65 are portions recessed inward in the width direction W at the outer edge of the main body portion of the absorbent article (the portion of the absorbent article other than the fixing member 90 described later). In the present embodiment, the outer edge is an outer edge in the width direction, and the inner edge is an inner edge in the width direction.

The absorbent article 10 has an absorbent core 30 disposed at least in the crotch region S3. The absorbent core 30 may extend from the crotch region S3 to the front waistline region S1 and the back waistline region S2. The absorbent core 30 may be, for example, a laminate of absorbent materials containing comminuted pulp or superabsorbent polymer (SAP) or mixtures thereof. The absorbent article 10 may have an absorbent body including an absorbent core 30 and a core wrap (not shown). The core wrap may be disposed so as to cover the skin surface side and the non-skin surface side of the absorbent core 30, and may be, for example, a tissue paper or a nonwoven fabric sheet.

The absorbent article 10 may have a skin-facing sheet 41 positioned on the skin-facing side T1 of the absorbent core 30 and a non-skin-facing sheet 42 positioned on the non-skin-facing side T2 of the absorbent core 30. The skin sheet 41 may have a surface sheet 41a and side sheets 41b. The top sheet 41a may have liquid permeability and be disposed so as to cover at least the center of the absorbent core 30 in the width direction W. The side sheet 41b may be made of a hydrophobic nonwoven fabric, and may be disposed so as to cover both side portions in the width direction W of the front sheet 41a on the outer side in the width direction W than the center in the width direction W of the absorbent core 30. The non-skin surface sheet 42 may have liquid impermeability and be provided on the non-skin surface side of the absorbent core 30. The non-skin-facing sheet 42 may include a liquid-impermeable back-side film 42a and a back-side nonwoven fabric 42b disposed on the non-skin-facing side T2 of the back-side film 42 a.

The absorbent article 10 may have fixing members 90 provided on both outer side portions in the width direction W of the rear waistline region S2. Fig. 4 is an enlarged plan view of the fixing member 90 shown in fig. 1. The fixing member 90 is configured to be fixable to the target region 80 provided in the front waistline region S1. The fixing members 90 extend from the main body portion to both widthwise outer sides in the rear waistline region S2. More specifically, the fixing members 90 extend outward in the width direction from the outer edge of the skin-facing sheet 41 and the outer edge of the non-skin-facing sheet 42. The fixing members 90 may be disposed on both sides in the width direction, and may be axisymmetric with respect to an article width center 10CW which is the center in the width direction of the absorbent article.

The fixing member 90 has a base 95 joined to the skin-facing sheet 41 and the non-skin-facing sheet 42 of the rear waistline region S2, and a 1 st flap 91 and a 2 nd flap 92 fixed to the base 95.

The 1 st cross edge 912 and the 2 nd cross edge 922 may extend in the width direction, and include not only a structure extending parallel to the width direction but also a structure inclined with respect to the width direction.

As shown in fig. 2, the target region 80 is a region to which the 1 st engaging portion 913 and the 2 nd engaging portion 923 of the fixing member are fixed when worn. The target region 80 may be a region having a ring member to which an engagement portion as a hook member is fixed, or may be provided across the entire front waistline region in a configuration in which the engagement portion can be engaged with the entire surface of the non-skin surface sheet 42. The engaging portion of the present embodiment is configured to be fixable to the back-side nonwoven fabric 42b, and the target region 80 is a region where the back-side nonwoven fabric 42b is arranged. However, in order to fix the fixing member 90 at an appropriate position, it is preferable to fix the fixing member 90 within a certain range, and a marking portion serving as a mark for fixing the fixing member 90 is provided in the target region 80 of the present embodiment. The mark portion is configured to be visually recognizable from the non-skin surface side of the absorbent article. The marking portion may be printed on the back side film 42a or may be printed on the back side nonwoven fabric 42b.

Fig. 5 is an enlarged plan view of the marker shown in fig. 2. The marking portion has a 1 st marking portion 51 and a 2 nd marking portion 52. The 2 nd mark portion 52 is located on the rear side of the 1 st mark portion 51. The 1 st mark part 51 and the 2 nd mark part 52 are arranged in the front-rear direction L. The 1 st mark portion 51 and the 2 nd mark portion 52 may partially overlap or may be separated. The 1 st mark 51 is a mark for fixing the 1 st flap 91. The 1 st mark part 51 has a 1 st outer end pattern 511 similar to the 1 st outer end edge 911 and a 1 st intersecting pattern 512 similar to the 1 st intersecting edge 912.

The 1 st outer end pattern 511 and the 1 st cross pattern 512 may be connected or separated.

The 2 nd mark portion 52 is a mark for the fixing position of the 2 nd flap 92. The 2 nd flag 52 has a 2 nd outer end pattern 521 similar to the 2 nd outer end edge 921 and a 2 nd crossing pattern 522 similar to the 2 nd crossing edge 922. The 2 nd crossing pattern 522 may have at least one of a front 2 nd crossing pattern F522 similar to the front 2 nd crossing edge F922 and a rear 2 nd crossing pattern R522 similar to the rear 2 nd crossing edge R922. The front 2 nd intersecting pattern F522 is located on the rear side of the rear 2 nd intersecting pattern R522. The 2 nd outer end pattern 521 and the 2 nd cross pattern 522 may be connected or separated.

The 1 st mark part 51 may have at least the 1 st outer end pattern 511 and the 1 st cross pattern 512, and may have a non-similar portion that is not similar to the outer shape of the 1 st flap 91. The non-similar portion is, for example, a portion different from the shape and angle, shape of the tab. For example, the 1 st mark part 51 may have a non-similar portion between the 1 st outer end pattern 511 and the 1 st cross pattern 512, or the non-similar portion may be connected to the 1 st outer end pattern 511, or the non-similar portion may be connected to the 1 st cross pattern 512. Similarly, the 2 nd marking part 52 may have at least the 2 nd outer end pattern 521 and the 2 nd cross pattern 522, and may have a non-similar portion that is not similar to the outer shape of the 2 nd flap 92. For example, the 2 nd marking part 52 may have a non-similar portion between the 2 nd outer end pattern 521 and the 2 nd crossing pattern 522, may have the non-similar portion connected to the 2 nd outer end pattern 521, and may have the non-similar portion connected to the 2 nd crossing pattern 522.

The 1 st mark part 51 may be provided in plurality at intervals in the width direction W so as to represent the fixing position of the 1 st flap 91 in stages. The 1 st mark 51 may include an outer 1 st mark 51X and an inner 1 st mark 51Y disposed on the inner side in the width direction W than the outer 1 st mark 51X. The 1 st mark 51 may have an intermediate 1 st mark 51Z disposed between the outer 1 st mark 51X and the inner 1 st mark 51Y. The outer 1 st mark portion 51X, the inner 1 st mark portion 51Y, and the intermediate 1 st mark portion 51Z may be separated in the width direction W or may be partially continuous.

The 2 nd mark part 52 may be provided in plural at intervals in the width direction W so as to indicate the fixing position of the 2 nd fin 92 in stages. The 2 nd mark portion 52 may include an outer 2 nd mark portion 52X and an inner 2 nd mark portion 52Y disposed on the inner side in the width direction W than the outer 2 nd mark portion 52X. The 2 nd mark part 52 may have an intermediate 2 nd mark part 52Z disposed between the outer 2 nd mark part 52X and the inner 2 nd mark part 52Y. The outer 2 nd mark portion 52X, the inner 2 nd mark portion 52Y, and the intermediate 2 nd mark portion 52Z may be separated in the width direction W or may be partially continuous.

Next, a fixing mode of the fixing member 90 of the absorbent article 10 configured as above will be described. Fig. 6 is a diagram showing a state in which the fixing member 90 is fixed to the target region 80. Specifically, the 1 st flap 91 is aligned with and fixed to the outer 1 st mark 51X, and the 2 nd flap 92 is aligned with and fixed to the outer 2 nd mark 52X. When the absorbent article 10 is worn on the wearer, the fixing member 90 is pulled toward the front waistline region S1 side in a state where the rear waistline region S2 is brought into contact with the back side of the wearer and the front waistline region S1 is brought into contact with the abdomen side of the wearer, and the left and right 1 st flaps 91 and the left and right 2 nd flaps 92 are fixed to the target region 80. That is, the absorbent article 10 having the 1 st flap 91 and the 2 nd flap 92 performs an operation of fixing a total of four flaps to the target area 80. At this time, since the plurality of flaps are provided in the upper, lower, left, and right directions depending on the wearer, the fixing member 90 may not be disposed at an appropriate position. In addition, depending on the wearer, the position of the 1 st flap 91 and the position of the 2 nd flap 92 may be confused, and the fixing member may not be disposed at an appropriate position.

The absorbent article 10 of the present embodiment is configured such that the wearer can grasp the position to which each flap is fixed by the marking portion. Specifically, the 1 st flag 51 is a pattern similar to the two intersecting edges (the 1 st outer end edge and the 1 st intersecting edge) of the 1 st flap 91, and the 2 nd flag 52 is a pattern similar to the two intersecting edges (the 2 nd outer end edge and the 2 nd intersecting edge) of the 2 nd flap 92. The wearer can align both sides of the 1 st mark part 51 with both sides of the 1 st flap, and can appropriately grasp the position where the 1 st flap 91 is aligned with the 1 st mark part 51. Similarly, the wearer can align both sides of the 2 nd marking part 52 with both sides of the 2 nd flap, and can appropriately grasp the position where the 2 nd flap 92 is aligned with the 2 nd marking part 52. Further, since the 1 st tab 51 and the 2 nd tab 52 are arranged in the front-rear direction L, the positions at which the 1 st flap 91 and the 2 nd flap 92 arranged in the front-rear direction L are fixed are not easily confused. Thus enabling the individual tabs to be secured in place.

The 1 st cross pattern 512 and the 2 nd cross pattern 522 may extend so as to approach each other in the front-rear direction L as going toward the inside in the width direction W. That is, the 1 st cross pattern 512 may extend toward the inner side of the width direction W toward the rear side, and the 2 nd cross pattern 522 may extend toward the inner side of the width direction W toward the front side. The 1 st flap 91 and the 2 nd flap 92 can be disposed so as to approach each other inward in the width direction W. The angle of the 1 st flap 91 and the angle of the 2 nd flap 92 can be guided, and the fixing member 90 can be fixed so as to increase the force of fastening with respect to the center of the wearer's abdomen in the width direction W.

The distance between the inner 1 st mark portion 51Y and the inner 2 nd mark portion 52Y in the front-rear direction L may be shorter than the distance between the outer 1 st mark portion 51X and the outer 2 nd mark portion 52X in the front-rear direction L. When the fixing positions of the flaps are selected in stages and fixed at positions closer to the article width center 10CW, the 1 st flap 91 and the 2 nd flap 92 can be disposed so as to be close to each other, and the fixing member 90 can be fixed so as to increase the force of fastening with respect to the center of the wearer's abdomen in the width direction.

The 1 st mark portion 51 and the 2 nd mark portion 52 may be separated in the front-rear direction L. With this configuration, the positions at which the 1 st flap 91 and the 2 nd flap 92 arranged in line in the front-rear direction L are fixed can be more easily distinguished, and the respective flaps can be fixed at appropriate positions. Note that, as long as a portion where the 1 st mark part 51 and the 2 nd mark part 52 are separated is provided, the 1 st mark part 51 and the 2 nd mark part 52 may be separated over the entire range, or the 1 st mark part 51 and the 2 nd mark part 52 may be partially separated.

The 1 st mark 51 and the 2 nd mark 52 may partially overlap each other and indicate a portion where the mark of the flap preceding the wearing order is missing. That is, in the state of being fixed in the correct fixing order, the state of the flap visible to the wearer can be indicated by the mark portion. In the present embodiment, the 1 st mark portion 51 partially overlaps the 2 nd mark portion 52, the 2 nd mark portion 52 is a shape in which a part of the 2 nd flap 92 is missing, and the 1 st mark portion 51 is a shape in which the 1 st flap 91 is not missing, and is shown to overlap the 2 nd mark portion 52. Thus, the wearer can grasp the correct fastening order of the flaps, and can grasp that the 1 st flap 91 is fastened to overlap the 2 nd flap 92, that is, that the 2 nd flap 92 is fastened first and the 1 st flap 91 is fastened next.

The 1 st mark part 51 may have a 1 st engagement pattern 513 similar to the 1 st engagement part 913, and the 2 nd mark part 52 may have a 2 nd engagement pattern 523 similar to the 2 nd engagement part 923. The position of the 1 st engaging portion 913 can be directly aligned with the 1 st engaging pattern 513, and the position of the 2 nd engaging portion 923 can be directly aligned with the 2 nd engaging pattern 523. This can fix the engagement portion of the fin at a more appropriate position. The 1 st engagement pattern 513 and the 2 nd engagement pattern 523 preferably do not overlap.

The 1 st mark part 51 may be larger than the outer shape of the 1 st flap 91, and the 2 nd mark part 52 may be larger than the outer shape of the 1 st flap 91. Specifically, the length of the 1 st outer end pattern 511 may be longer than the 1 st outer end edge 911. The length of the 1 st cross pattern 512 may be longer than the 1 st cross edge 912. The 2 nd outer end pattern 521 may have a length longer than the 2 nd outer end edge 921. The length of the 2 nd crossing pattern 522 may be longer than the 2 nd crossing edge 922. As shown in fig. 6, in a state where the 1 st flap 91 is aligned with the 1 st mark part 51, the 1 st mark part 51 is not entirely covered with the 1 st flap 91, and in a state where the 2 nd flap 92 is aligned with the 2 nd mark part 52, the 2 nd mark part 52 is not entirely covered with the 2 nd flap 92. Therefore, the 1 st tab 51 and the 2 nd tab 51 can be visually recognized with the 1 st tab 91 and the 2 nd tab 92 fixed, and whether or not the tab fixing positions are appropriate can be determined. The fastening position of the wings can be corrected as desired so that the respective wings are fastened in place.

More preferably, the 1 st mark part 51 may have a portion larger than the outer shape of the 1 st flap 91 and a portion smaller than the outer shape of the 1 st flap 91. That is, the 1 st mark part 51 may have a shape spanning the outer edge of the 1 st flap 91. Likewise, the 2 nd marker 52 may have a portion larger than the outer shape of the 2 nd flap 92 and a portion smaller than the outer shape of the 2 nd flap 92. That is, the 2 nd marker 52 may be shaped to span the outer edge of the 2 nd tab 92. The 1 st flap 91 can be fixed so as to overlap the 1 st mark portion 51. Further, since the 1 st mark part 51 can be seen even after the fixing, it is possible to determine whether the fixing position of the 1 st flap 91 is appropriate. Similarly, the 2 nd flap 92 can be fixed so as to overlap the 2 nd mark portion 52. Further, since the 2 nd mark portion 52 can be seen even after the fixing, it is possible to determine whether or not the fixing position of the 2 nd fin 92 is appropriate.

In the case where the mark portions represent the fixing positions of the flaps in stages, the appearance of each mark portion may be different. Specifically, the outer 1 st mark part 51X may have the 1 st recognition part 515 having a color difference Δ E of 3.0 or more with respect to the inner 1 st mark part 51Y. The 1 st recognizer 515 may have a color difference Δ E of 3.0 or more with respect to the intermediate 1 st marker 51Z. In the present embodiment, the 1 st engagement pattern 513 of the outer 1 st mark portion 51X, the 1 st engagement pattern 513 of the inner 1 st mark portion 51Y, and the 1 st engagement pattern 513 of the intermediate 1 st mark portion 51Z function as the 1 st recognition portion 515, respectively, and the difference in the color difference therebetween is 3.0 or more. The outer 2 nd mark portion 52X may have a 2 nd recognition portion 525 having a color difference Δ E of 3.0 or more with respect to the inner 2 nd mark portion 52Y. The 2 nd identifier 525 may have a color difference Δ E of 3.0 or more with respect to the intermediate 2 nd mark portion 52Z. In the present embodiment, the 2 nd engagement pattern 523 of the outer 2 nd mark part 52X, the 2 nd engagement pattern 523 of the inner 2 nd mark part 52Y, and the 2 nd engagement pattern 523 of the intermediate 2 nd mark part 52Z function as the 2 nd recognition part 525, respectively, and the difference in the color difference therebetween is 3.0 or more.

As a result of various studies, the applicant found that, in general, when the color difference Δ E is 3.0 or more, the user can easily recognize two regions as different regions. The wearer can select the outer 1 st mark part 51X and the inner 1 st mark part 51Y, and select the outer 2 nd mark part 52X and the inner 2 nd mark part 52Y according to the body size of the wearer and the like. At this time, the wearer can easily distinguish the outer 1 st mark part 51X from the inner 1 st mark part 51Y by the 1 st recognition part 515, and can easily distinguish the outer 2 nd mark part 52X from the inner 2 nd mark part 52Y by the 2 nd recognition part 525. Therefore, the 1 st flap 91 can be fixed at a position suitable for the body shape of the wearer without confusing the outer 1 st tab 51X and the inner 1 st tab 51Y, and the 2 nd flap 92 can be fixed at a position suitable for the body shape of the wearer without confusing the outer 2 nd tab 52X and the inner 2 nd tab 52Y.

In addition, as another mode of making the appearance of the mark portions which stepwise indicate the fixing positions of the fins different, the patterns of the mark portions may be different, or the thickness and shape of the lines may be different. The 1 st identification portion of the outer 1 st mark portion 51X and the 2 nd identification portion of the outer 2 nd mark portion 52X may be the same color or pattern, and the 1 st identification portion of the inner 1 st mark portion 51Y and the 2 nd identification portion of the outer 2 nd mark portion 52X may be the same color or pattern. According to this configuration, an operation error in which the 1 st flap and the 2 nd flap are fixed at different stages (for example, the outer 1 st mark part 51X and the inner 2 nd mark part 52Y) is less likely to occur, and the 1 st flap and the 2 nd flap are easily fixed at the same stage (for example, the outer 1 st mark part 51X and the outer 2 nd mark part 52X).

The 1 st mark portions 51 are disposed on both sides with respect to the article width center 10CW, and the 2 nd mark portions 52 are disposed on both sides with respect to the article width center 10 CW. The wearer can fix the left and right flaps on both sides of the article width center 10 CW. The 1 st mark section 51 and the 2 nd mark section 52 may be axisymmetric with respect to the article width center 10 CW. The left and right fins can be fixed symmetrically. A center mark portion 55 extending in the front-rear direction may be provided between the 1 st mark portion 51 and the 2 nd mark portion 52. By aligning the center mark portion 55 with the center of the body, the absorbent article 10 can be worn at a more appropriate position.

At least one of the 1 st mark part 51 and the 2 nd mark part 52 may be disposed in a region overlapping the absorbent core 30. By fixing at least one of the 1 st flap 91 and the 2 nd flap 92, the absorbent core 30 can be pressed. The adhesiveness of the absorbent core 30 can be improved, and leakage can be suppressed.

The 1 st mark portion 51 and the 2 nd mark portion 52 may be disposed on the rear side of the front end edge 30F of the absorbent core 30. At least one of the 1 st mark portion 51 and the 2 nd mark portion 52 may span the front end edge 30F of the absorbent core 30. According to this structure, by fixing at least one of the 1 st flap 91 and the 2 nd flap 92, the front end edge of the absorbent core 30 can be pressed. The close adhesion of the absorbent core 30 can be improved, and leakage due to the front end edge 30F of the absorbent core 30 hanging up from the body can be suppressed.

The 1 st cross pattern 512 may extend along the front end edge 30F of the absorbent core 30. The front end edge 30F of the absorbent core 30 of the present embodiment extends rearward as it goes inward in the width direction W. That is, the front end edge 30F of the absorbent core 30 is curved rearward toward the article width center 10 CW. The 1 st cross pattern 512 may extend to the rear side as facing the inner side in the width direction W. By fixing the 1 st flap 91 along the 1 st cross pattern 512 of the 1 st mark part 51, the absorbent core 30 can be pressed along the shape of the front end edge 30F of the absorbent core 30. Leakage due to the front end edge 30F of the absorbent core 30 hanging from the body can be suppressed.
