Detailed Description

(1) Brief description of the embodiments

At least the following matters will be apparent from the description of the present specification and the accompanying drawings.

An absorbent article according to one aspect includes: a front-back direction and a width direction orthogonal to each other; a crotch region including a center in the front-rear direction, a front region located on a front side of the crotch region, and a rear region located on a rear side of the crotch region; and an absorbent core disposed at least in the crotch region and the front region, wherein the absorbent core is provided with a pair of side slits extending in the front-rear direction in the crotch region and a deformation guide extending outward in the width direction toward the front side in the front region, and the width of the deformation guide is smaller than the width of the side slits.

The absorbent core in the crotch region is provided with side slits. The absorbent core may be entered into the width direction inside in the lower crotch region through the side slits. Since the absorbent core in the crotch region has a short length in the width direction, the absorbent core is easily accommodated in the crotch, and discomfort during wearing can be suppressed.

In addition, the absorbent core in the front side region is provided with a deformation guide. The deformation guide portion extends toward the outer side in the width direction, and can deform the absorbent core along the groin portion. At this time, if the length in the width direction of the deformation guide portion is too long, the length in the width direction of the deformed portion of the absorbent core becomes long, and the length of the portion of the absorbent core disposed along the body becomes short, which may cause leakage in the front region. However, since the width of the deformation guide portion is smaller than the width of the side slit, the length of the absorbent core in the width direction in the front region can be secured, and leakage in the front region can be suppressed. Thus, the front region can be attached along the groin of the wearer while suppressing leakage.

According to a preferred aspect, the deformation guide portion may be formed of at least one of a low basis weight region in which a basis weight of an absorbent material of the absorbent core is lower than that of a periphery thereof, a compressed portion in which the absorbent core is compressed in a thickness direction, a slit formed in the absorbent core, and a structure having a rigidity difference of the absorbent core.

According to a preferred aspect, the absorbent article may have a topsheet on the skin surface side of the absorbent core and raised leakage preventing gathers on the skin surface side of the topsheet, the leakage preventing gathers having a contracted portion raised by contraction of a leakage preventing elastic member and a base point portion serving as a standing base point of the contracted portion, the absorbent core may have a 1 st region sandwiched by the side slits and a 2 nd region located between the side slits and the outer edge of the absorbent core, and the contracted portion may overlap the 2 nd region in the thickness direction.

Since the absorbent article is sandwiched by the legs during wearing, a force directed inward in the width direction is applied to the absorbent core. At this time, the 2 nd region of the absorbent core is pulled inward in the width direction and toward the skin surface side by contraction of the contraction portion. Since the contracted portion overlaps the 2 nd region in the thickness direction, a force is generated that pulls the 2 nd region inward in the width direction and toward the skin surface side. When a force is applied from the outside to the inside in the width direction during wearing, the 2 nd area is easily moved to the skin surface side of the 1 st area and to the inside in the width direction. Therefore, the length of the absorbent core in the width direction is easily shortened.

According to a preferred aspect, the absorbent core may be formed with a central slit that is located between the side slits in the width direction and extends in the front-rear direction.

According to this aspect, the region between the side slits is easily bent in the thickness direction by the central slit, and the length in the width direction of the entire absorbent core in the lower crotch region can be further shortened.

According to a preferred aspect, the side slits may have a rear narrow portion in which the length of the side slits in the width direction becomes shorter toward the rear side, and the rear narrow portion may reach rear end edges of the side slits.

According to this aspect, since the side slits have the rear narrow width portion, the length of the absorbent core in the crotch region that becomes shorter in the width direction becomes shorter toward the rear side during wearing. That is, the length of the absorbent core in the width direction can be secured in a certain region including the rear end edge of the side slit. The length of the absorbent core in the width direction on the hip side is ensured, the hip is covered by the absorbent core, and leakage in the region corresponding to the hip is suppressed. By making the length of the absorbent core in the width direction shorter by the side slits, an effect of suppressing a feeling of incongruity can be obtained, and leakage in the region corresponding to the buttocks is suppressed by the absorbent core.

According to a preferred aspect, the side slits may have a front narrow portion in which the length of the side slits in the width direction becomes shorter toward the front side, and the front narrow portion may reach a front end edge of the side slits.

According to this aspect, since the side slits have the front narrow width portion, the length of the absorbent core in the crotch region that becomes shorter in the width direction becomes shorter toward the front side during wearing. That is, the length of the absorbent core in the width direction can be secured in a certain region including the front end edges of the side slits. The length of the absorbent core in the width direction on the urination port side can be secured, and leakage in the urination region can be suppressed.

According to a preferred embodiment, the absorbent core may have: a 1 st region sandwiched by the side slits; a 2 nd region located between the side slit and the outer edge of the absorbent core; a 3 rd region sandwiched by the deformation guide portions; and a 4 th region located between the deformation guide and an outer edge of the absorbent core, wherein a maximum length in the width direction of the 3 rd region is larger than a maximum length in the width direction of the 1 st region.

According to this aspect, the 3 rd region sandwiched by the deformation guide portions can secure a length in the width direction more than the 1 st region sandwiched by the side slits, and the body can be covered with the absorbent core over a wide range. The length of the absorbent core in the width direction in the front region can be ensured, and leakage in the front region can be suppressed.

According to a preferred aspect, the width of the deformation guide portion may be 1/2 or less of the width of the side slit.

According to this aspect, the effect of being able to fit along the groin of the wearer while suppressing leakage in the front region can be further obtained.

According to a preferred aspect, the deformation guide may be located inward in the width direction from an outer edge of the absorbent core.

According to this aspect, the outer edge of the absorbent core can be brought into surface contact with the body without being deformed by the deformation guide. Thus, leakage in the front region can be further suppressed. In the case where the deformation guide portion is formed of a slit, the absorbent material is present at a position outside the deformation guide portion in the width direction. The body fluid diffused by the deformation guide can be retained by the absorbent material, and side leakage can be suppressed.

According to a preferred aspect, the absorbent article may have a topsheet positioned on the skin surface side of the absorbent core and raised leakage preventing gathers positioned on the skin surface side of the topsheet, the leakage preventing gathers having a contracted portion raised by contraction of a leakage preventing elastic member and a base point portion serving as a standing base point of the contracted portion, and the leakage preventing elastic member may overlap the deformation guide portion in the thickness direction.

According to this aspect, the deformation guide portion is pulled toward the skin surface side by the contraction of the contraction portion. The absorbent core is deformed in the thickness direction with the deformation guide portion as a base point, and the deformed portion can be arranged close to the body. Thus, the absorbent core will be more body conforming and leakage will be inhibited.

According to a preferred aspect, the leakage preventing elastic member may not overlap a region located forward of the center of the deformation guide portion in the front-rear direction, but may overlap a region located rearward of the center of the deformation guide portion in the front-rear direction.

According to this aspect, the region on the rear side of the center in the front-rear direction of the deformation guide portion is pulled up toward the skin surface side by contraction of the leakage preventing elastic member, and is easily fit along the body. On the other hand, the region located forward of the center in the front-rear direction of the deformation guide portion is less likely to be pulled up toward the skin surface side by contraction of the leakage-preventing elastic member, and can be easily arranged to cover the body while maintaining a planar shape. By arranging the absorbent core in such a way as to cover the body, leakage can be suppressed.

According to this aspect, the absorbent core in the front region is provided with the front mark portion that can be recognized from the skin surface side of the absorbent article and the non-skin surface side of the absorbent article. The front mark portion extends toward the front side and outward in the width direction, and is arranged along the inguinal portion. The groin portion is difficult to be hidden by clothing or an absorbent article during wearing, and is easily visible to a wearer assistant positioned on the side of the wearer. The front mark portion can be aligned with respect to the groin portion of the wearer to align the absorbent article in a proper position.

According to a preferred embodiment, the front mark portion may be a slit formed in the absorbent core.

According to this aspect, the absorbent core is easily deformed with the front mark section as a base point. Therefore, the aforementioned mark portion can be aligned with the inguinal portion, and the aforementioned mark portion can be arranged along the inguinal portion. Thus, the absorbent article can be aligned in position and the absorbent core can be arranged along the groin portion. In addition, by deforming the absorbent core with the slits as the base points, wrinkles are generated around the slits in the skin surface and the non-skin surface of the absorbent article. The wrinkles form marks, and the absorbent article can be more easily placed at an appropriate position on the body.

According to a preferred aspect, the absorbent article may include a skin-facing sheet positioned on a skin surface side of the absorbent core and a non-skin-facing sheet positioned on a non-skin facing side of the absorbent core, and the skin-facing sheet and the non-skin-facing sheet may be joined to each other in a region overlapping the slit.

According to this aspect, the skin surface sheet and the non-skin surface sheet are joined together, and the slit is tightly attached to the skin surface sheet and the non-skin surface sheet, thereby improving the visibility of the slit. The visibility of the mark portion formed by the slit is improved, and the absorbent article can be aligned more easily to a proper position.

According to a preferred embodiment, the absorbent core may be provided with a compressed portion obtained by compressing the absorbent core at least in the thickness direction in any one of a region adjacent to the inner edge of the slit and a region adjacent to the outer edge of the slit.

According to this aspect, the absorbent core is compressed in the pressing section, and the visibility of the edge of the slit constituting the front mark section is improved, thereby improving the visibility of the front mark section.

According to a preferred aspect, the absorbent core may be provided with a pair of crotch marks extending in the front-rear direction in the crotch region, and the crotch marks may be visible from the skin surface side of the absorbent article and the non-skin surface side of the absorbent article.

According to this aspect, even in a position closer to the crotch than the inguinal portion, the positioning with respect to the body can be performed by the crotch mark portion. The front mark portion extends outward in the width direction, and the crotch mark portion extends in the front-rear direction. Since the front mark portion and the crotch mark portion extend in different directions, the boundary therebetween is easily conspicuous. Therefore, the region to be disposed along the groin portion can be easily grasped, and the absorbent article can be more easily aligned to an appropriate position.

According to a preferred aspect, the absorbent article may include a non-skin surface sheet positioned on a non-skin-facing side of the absorbent core, the non-skin surface sheet may include a printed portion that is visible from the non-skin surface side of the absorbent article, and the printed portion may include a 1 st printed portion that overlaps an outer edge of the front mark portion and a 2 nd printed portion that overlaps an outer edge of the crotch mark portion.

According to this aspect, the wearing assistant can easily grasp the front mark portion by the 1 st printing unit and can easily recognize the crotch mark portion by the 2 nd printing unit. The boundary between the front mark portion and the crotch mark portion is easily grasped, the region to be arranged along the inguinal portion is easily grasped, and the absorbent article is more easily aligned to an appropriate position.

According to the absorbent article relating to a preferred aspect, the width of the front mark portion may be smaller than the width of the crotch mark portion.

According to this aspect, the wearing assistant can easily grasp the front mark portion and the crotch mark portion. The boundary between the front mark portion and the crotch mark portion is easily grasped, the region to be arranged along the inguinal portion is easily grasped, and the absorbent article is more easily aligned to an appropriate position.

According to a preferred aspect, the absorbent article may include a non-skin surface sheet positioned on a non-skin-facing side of the absorbent core, the non-skin surface sheet including an outer sheet constituting the non-skin surface of the absorbent article, the outer sheet being formed with embossed portions, the embossed portions being disposed in a region overlapping the front mark portion.

According to this aspect, the thickness of the non-skin surface sheet is reduced by the embossing portion. Therefore, the visibility of the front mark portion from the non-skin surface side of the absorbent article can be improved.

(2) Embodiment 1

The disposable diaper according to embodiment 1 will be described below with reference to the drawings. In the following description of the drawings, the same or similar parts are denoted by the same or similar reference numerals. It should be noted that the drawings are schematic configurations, and ratios of the respective dimensions and the like are different from actual ones. Therefore, the specific dimensions and the like should be determined in consideration of the following description. In addition, the drawings may include portions having different dimensional relationships or ratios from each other.

The absorbent article of embodiment 1 is configured to be fitted along the groin of the wearer while suppressing leakage in the front region while suppressing a feeling of discomfort in wearing in the lower crotch region. In the related art, an absorbent article having a slit extending in the front-rear direction is disclosed. The slits of the prior art extend outward in the width direction from the crotch region toward the front region, function as urine diffusion paths, and diffuse urine in the front-back direction. In addition, as a conventional slit, a slit reaching the outer edge of the absorbent body is disclosed. The absorbent body having the slit is separated into a center absorbent body and a side absorbent body by the slit. In the absorbent article having the above-described configuration, when a force for pulling the front portion side of the center absorbent body toward the crotch portion side is applied, first, the front portion side of the center absorbent body is pulled toward the crotch portion side, and the side absorbent bodies positioned on both sides are pulled toward the crotch portion side with a slight delay from the front portion side of the center absorbent body due to the force. The absorbent body is attached along the groin of the wearer by such movement. However, in the absorbent article of the related art, when a force directed inward in the width direction is applied during wearing, the slit is deformed, and the length of the absorber in the width direction may become short. The slits are arranged across the crotch region and the front region, and the width of the absorbent body is shortened in the crotch region and also shortened in the front region. The crotch region is a region sandwiched between the legs, and the length of the absorbent core in the width direction of the crotch region is shortened, thereby suppressing a feeling of discomfort when worn. However, the front region is a region where urine is discharged, and if the length of the front region in the width direction of the absorbent core cannot be secured, leakage may occur. The present invention has been made in view of the above problems, and is configured to be able to fit along the groin of the wearer while suppressing a feeling of discomfort when worn in the lower crotch region and suppressing leakage in the front region.

Fig. 1 is a plan view of an absorbent article 10 according to embodiment 1 viewed from the skin surface side, and fig. 2 is a plan view of an absorbent core 50 according to embodiment 1 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 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 be a pants-type absorbent article, or may be a child-use absorbent article.

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 front side and the back side of the body. 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 of the wearer and the non-skin surface side T2 of the wearer. In this specification, the "skin surface side" corresponds to the side facing the skin of the wearer during use. The "non-skin-side" corresponds to the side facing opposite the skin of the wearer during use.

The absorbent article 10 has a front region S1, a rear region S2, and a crotch region S3. The front region S1 faces the front side of the wearer' S body in use. The rear region S2 faces the rear side of the wearer' S body in use. The crotch region S3 is located between the front region S1 and the back region S2, and is disposed in the crotch of the wearer during use. The crotch region S3 can be defined by the absorbent core 50. Specifically, in the absorbent core 50 having the neckdown portion 51, the region of the absorbent core 50 where the neckdown portion 51 is formed is a region in the front-rear direction L of the crotch region S3. In the absorbent core 50 without the neckdown portion 51, a central region among regions obtained by trisecting the longitudinal length of the absorbent core 50 is a region in the longitudinal direction L of the crotch region S3. In the present embodiment, the front end edge of the neckdown portion 51 of the absorbent core 50 defines the boundary between the crotch region S3 and the front region S1, and the rear end edge of the neckdown portion 51 of the absorbent core defines the boundary between the crotch region S3 and the rear 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 (portions of the absorbent article other than the fastening tape 94 described later).

The absorbent article 10 has an absorbent core 50 disposed in at least the crotch region S3 and the front region S1. The absorbent core 50 may extend from the crotch region S3 to the front region S1 and the back region S2. The absorbent core 50 may be, for example, a laminate of comminuted pulp or a superabsorbent polymer (SAP) or an absorbent material comprising a mixture thereof. As shown in fig. 3, the absorbent article 10 may have an absorbent body comprising an absorbent core 50 and a core wrap sheet 56. The core wrap sheet 56 is disposed so as to cover the skin surface side and the non-skin surface side of the absorbent core 50, and may be, for example, a thin paper sheet or a nonwoven fabric sheet. The structure of the absorbent core 50 will be described in detail later.

As shown in fig. 3, the absorbent article 10 may have a skin-facing sheet 41 positioned on the skin-facing side T1 of the absorbent core 50 and a non-skin-facing sheet 42 positioned on the non-skin-facing side T2 of the absorbent core 50. The skin sheet 41 may have a core wrap sheet 56, a surface sheet 41a, and a side sheet 41b on the skin surface side T1 of the absorbent core 50. The top sheet 41a may have liquid permeability and be disposed so as to cover at least the center of the absorbent core 50 in the width direction W. The side sheet 41b may be made of a hydrophobic nonwoven fabric, and is disposed to cover both side portions of the front sheet 41a in the width direction W at a position outside the center of the absorbent core 50 in the width direction W. The non-skin surface sheet 42 may have liquid impermeability and is provided on the non-skin surface side of the absorbent core 50. The non-skin-facing sheet 42 may include a core wrap sheet 56 positioned on the non-skin-facing side T2 of the absorbent core 50, a liquid-impermeable back film 42a, and an outer sheet 42b disposed on the non-skin-facing side T2 of the back film 42 a. The exterior sheet 42b may be formed of a nonwoven fabric.

The absorbent article 10 may have standing leak-proof gathers 60. The leakproof gathers 60 are positioned on the skin surface side of the top sheet 41a and can stand up against the top sheet 41 a. The leakage preventing gathers 60 have contracted portions 61 that rise up by contraction of the leakage preventing elastic members 66, and origin points 62 that serve as origin points of erection of the contracted portions 61. The base point portion 62 may have a 1 st base point portion 62a (see fig. 3) located on the outer side in the width direction W than the constricted portion 61 and a 2 nd base point portion 62b (see fig. 1) located on the outer side in the front-rear direction L than the constricted portion 61. The leakage-preventing elastic member 66 is disposed on the inner edge of the side sheet 41b, and stands up the inner edge of the side sheet 41b toward the wearer.

The absorbent article 10 may have leg hole elastic members 67 disposed in the leg hole openings 65. The leg hole elastic members 67 are disposed along the leg hole opening portions 65, and the leg hole opening portions 65 are fitted to the leg holes of the wearer. The leg elastic members 67 are disposed between the side sheet 41b and the back film 42 a. The leakage preventing elastic member 66 and the leg hole elastic member 67 are stretchable in the front-rear direction L and are disposed along the front-rear direction L.

The absorbent article 10 may have fastening tapes 94 provided on both outer sides in the width direction W of the rear region S2. The hook and loop fastener 94 may have an engaging portion 96 that engages with the non-skin surface of the front region S1.

Next, the structure of the absorbent core 50 will be described in detail. The absorbent core 50 may be formed with slits and deformation guides 54. The slits are portions where substantially no absorbent material constituting the absorbent core 50 is arranged. The slits are portions where the absorbent material has a weight per unit area of 0 or portions where the absorbent material is designed to be 0 despite the fact that scattered absorbent material from the surroundings is arranged. The slits absorb deformation or become the base points of deformation when the absorbent core 50 is subjected to a force. The slits may have a pair of side slits 52 and a central slit 55.

As shown in fig. 2, the absorbent core 50 may have a 1 st region R1 sandwiched by the pair of side slits 52, a 2 nd region R2 located between the side slits 52 and the outer edge 50S of the absorbent core 50, a 3 rd region R3 sandwiched by the deformation guides 54, and a 4 th region R4 located between the pair of deformation guides 54 and the outer edge of the absorbent core 50. In fig. 2, the 1 st region R1, the 2 nd region R2, the 3 rd region R3, and the 4 th region R4 are indicated by hatching. The 2 nd regions R2 are located outside the respective side slits 52 in the width direction W, and are provided in pairs. The 1 st region R1 and the 2 nd region R2 are regions extending in the width direction W from the side slits 52. At least a part of the central slit 55 may be disposed in the 1 st region R1. The 3 rd regions R3 are located outside the respective deformation guide portions 54 in the width direction W, and are provided in pairs. The 3 rd region R3 and the 4 th region R4 are regions extending in the width direction W from the deformation guide 54.

The side slits 52 may be disposed at least in the crotch region S3. The front edges 52F of the side slits 52 can be disposed in the crotch region S3, and the rear edges 52R of the side slits 52 can be disposed in the crotch region S3. The side slits 52 may extend at least in the front-rear direction L, and may be along the front-rear direction L or may have a portion inclined with respect to the front-rear direction L. The length of the side slit 52 in the width direction W may be constant or may vary. The side slits 52 may not be provided at the center of the width direction W of the absorbent core 50, but may be provided in a pair symmetrically with respect to the center of the width direction W of the absorbent core 50.

The deformation guide 54 is configured to deform the absorbent core 50 in the thickness direction T. The absorbent core 50 is configured to deform from the deformation guide 54 as a base point when a force is applied during wearing or the like. The deformation guide 54 may be located on the front side than the side slit 52, at least in the front side region S1. The front end edge 54F of the deformation guide portion 54 is disposed in the front side region S1, and the rear end edge 54R of the deformation guide portion 54 is disposed in the crotch region S3. At least a part of the deformation guide 54 extends toward the front side outward in the width direction in the front side region S1.

The deformation guide 54 is configured by at least one of a low basis weight region in which the basis weight of the absorbent material of the absorbent core 50 is lower than the surrounding, a pressed portion in which the absorbent core 50 is compressed in the thickness direction T, a slit formed in the absorbent core 50, and a structure of poor rigidity of the absorbent core 50. The deformation guide 54 of the present embodiment is formed of a slit. The deformation guide 54 may be integrated with the side slit or may be separate. The deformation guide 54 of the present embodiment is formed integrally with the side slit 52. The rear end edges 54R of the deformation guide portions 54 may be continuous with the front end edges 52F of the side slits 52. The rear end edge 54R of the deformation guide portion 54 may be located on the front side with respect to the center in the front-rear direction L of the absorbent article 10, and may be located on the front side with respect to the center in the front-rear direction L of the absorbent core 50.

The width of the deformation guide 54 is smaller than the width of the side slit 52. The width of the side slit 52 is the length in the direction orthogonal to the longitudinal direction of the side slit 52, and the width of the side slit 52 extending in the front-rear direction L is the length in the width direction. Similarly, the width of the deformation guide 54 is the length in the direction orthogonal to the longitudinal direction of the deformation guide 54, and the width of the deformation guide 54 extending in the front-rear direction L is the length in the width direction. In the case of the side slit 52 and the deformation guide 54 being integrated, the boundary between the side slit 52 and the deformation guide 54 may be a portion having a varying width. In the configuration in which the width of the side slits 52 and the width of the deformation guide 54 are varied, the maximum width of the deformation guide 54 may be smaller than the maximum width of the side slits 52, or the average width of the deformation guide 54 may be smaller than the average width of the side slits 52.

Next, a modification of the absorbent article 10 configured as described above will be described. Fig. 4 is a view schematically showing a deformed state of the absorbent body when worn. Fig. 4 schematically showsbase:Sub>A deformation mode of the absorber in the crotch region S3 in thebase:Sub>A-base:Sub>A cross section, and fig. 5 showsbase:Sub>A deformation mode of the absorber in the front region S1 in the B-B cross section. Fig. 4 (a) shows a state in which a force directed inward in the width direction is applied during wearing, and fig. 4 (b) shows a state in which a force directed further inward in the width direction is applied from the state shown in fig. 4 (a). Fig. 5 (a) shows a state before wearing, and fig. 5 (b) shows a state during wearing. Fig. 6 is a view schematically showing an absorbent article in a state of being worn on a wearer.

When the absorbent article 10 is worn, the absorbent article 10 is sandwiched between the legs, and a force directed inward in the width direction W is applied to the crotch region S3 by the legs. As shown in fig. 4, when a force directed inward in the width direction W is applied to the absorbent body in the crotch region S3, the side slits 52 of the absorbent core 50 deform, and the 2 nd region R2 moves inward in the width direction W (arrow a in fig. 4 a), whereby the length of the absorbent body in the width direction W becomes shorter. The absorbent core 50 can enter the inside in the width direction through the side slits 52 in the crotch region S3. Since the length of the absorbent core 50 in the width direction in the crotch region S3 is shortened, the absorbent core 50 can be easily accommodated in the crotch, and the uncomfortable feeling during wearing can be suppressed.

The front region S1 of the absorbent article 10 is arranged to cover the abdomen and the groin of the body. Therefore, the absorbent body is deformed along the body, and the side portions in the width direction of the absorbent core are positioned on the skin surface side with respect to the center in the width direction of the absorbent core. The absorbent core 50 in the front region S1 is provided with a deformation guide 54. The deformation guide 54 extends toward the front side to the outside in the width direction. As shown in fig. 5 (b), the absorbent core 50 can be deformed along the groin portion with the deformation guide portion 54 as a base point. At this time, if the length of the deformation guide 54 in the width direction is too long, the length of the portion of the absorbent core 50 deformed in the width direction becomes long, and the length of the portion of the absorbent core 50 disposed along the body is short, so that there is a possibility that leakage may occur in the front region S1. However, since the width of the deformation guide 54 is smaller than the width of the side slits 52, the length of the absorbent core 50 in the width direction in the front region S1 can be secured, and leakage in the front region S1 can be suppressed. As shown in fig. 6, leakage in the front region S1 can be suppressed, and the absorbent core 50 can be fitted along the groin portion of the wearer.

In order to further obtain an effect that the uncomfortable feeling at the time of wearing in the crotch region S3 can be suppressed and the leakage in the front region S1 can be suppressed while fitting along the groin portion of the wearer, the width of the deformation guide portion 54 may be 1/2 or less of the width of the side slit 52. The distance of inward movement in the width direction obtained by the side slits 52 can be secured, and the distance of inward movement in the width direction in the front region S1 can be suppressed.

The center slit 55 may be located between the side slits 52 in the width direction W and extend in the front-rear direction L. The central slit 55 may be separated from the side slits 52 in the width direction and from the deformation guide 54 in the width direction. At least a portion of the central slit 55 may be disposed in the crotch region S3. The front edge 55F of the central slit 55 is disposed in the crotch region S3, and the rear edge 55R of the central slit 55 is disposed in the rear region S2. The center slit 55 may be located more rearward than the side slits 52, and the front end edge 55F of the center slit 55 may be located more rearward than the front end edge 52F of the side slits 52 and the rear end edge 54R of the deformation guide portion 54. The central slit 55 may extend at least in the front-rear direction L, and may have a portion inclined with respect to the front-rear direction L along the front-rear direction L.

The 1 st region R1 is easily bent in the thickness direction T by the central slit 55, and the length in the width direction of the entire absorber can be further shortened. More specifically, when a force is applied from the outside to the inside in the width direction during wearing, the absorbent core 50 is easily deformed so that the inside edge of the 1 st region R1 faces the skin surface side, as indicated by an arrow C in fig. 4 (a), with the outside edge (side slit 52) of the 1 st region R1 as the starting point. Thus, the widthwise length of the absorbent core 50 is easily made shorter. The absorbent core 50 in the crotch region S3 is deformed into a convex shape having the center in the width direction of the absorbent core 50 as the apex, and the length in the width direction of the entire absorbent core 50 can be further shortened. Further, the deformation of the absorbent body caused by the absorbent article 10 being sandwiched between the legs may be a deformation in a convex shape with the center of the absorbent body in the width direction as the apex, as shown in fig. 4 (a), or the 2 nd region R2 may be moved to the inside in the width direction without deforming the absorbent body in the thickness direction T. In the deformation in which the 2 nd region R2 slides, the length in the width direction of the absorbent core 50 also becomes shorter in accordance with the length in the width direction of the side slits 52.

In addition, when the absorbent article 10 is used, an absorbent pad may be used by being placed on the skin surface side of the absorbent article 10. At this time, in the crotch region S3, the 2 nd region R2 of the absorbent core 50 moves toward the skin surface side T1 of the 1 st region R1, whereby the skin surface of the absorbent core 50 is pushed up toward the wearer, and the absorbent pad can be disposed close to the skin surface. The absorbent pad can be fitted to the body and leakage can be further suppressed. In the front region S1, the 4 th region is deformed to rise toward the skin surface side with respect to the 3 rd region with the deformation guide portion 54 as a base point. By disposing the absorbent pad in the 3 rd region, the outer edge of the absorbent pad can be held so as to be sandwiched by the 4 th region. In this way, since the absorbent core 50 deforms along the groin portions in a state where the absorbent pad is held, the absorbent pad can be arranged along the region between the groin portions.

As shown in fig. 2, the side slits 52 may have a rear narrow portion 58 that is shorter in length in the width direction of the side slits 52 toward the rear side. The front end edge 58F of the rear narrow portion 58 may be located on the rear side of the center 52CL of the side slit 52 in the front-rear direction L. The rear end edge 58R of the rear narrow-width portion 58 can reach the rear end edge 52R of the side slit 52. The outer edges of the side slits 52 in the present embodiment are linear extending in the front-rear direction L, and the inner edges of the side slits 52 are bent outward in the width direction W at the rear narrow portion 58. Since the side slits 52 have the rear narrow width portion 58, the length of the absorbent core 50 in the crotch region S3 that becomes shorter in the width direction W becomes shorter toward the rear side when worn. That is, the length of the absorbent core 50 in the width direction is easily secured in a certain region including the rear end edges 52R of the side slits 52. The absorbent core 50 can secure the length in the width direction of the absorbent core 50 located on the hip portion side, and the hip portion is covered with the absorbent core 50, whereby leakage in the region corresponding to the hip portion can be suppressed. By making the length of the absorbent core 50 in the width direction W short by the side slits 52, an effect of suppressing a feeling of incongruity can be obtained, and leakage in the region corresponding to the buttocks can be suppressed by the absorbent core 50.

The side slits 52 may have a front narrow part 57 toward the front side and the width direction length of the side slits 52 becomes shorter. The front end edge 57F of the front narrow width portion 57 can reach the front end edge 52F of the side slit 52, and the rear end edge 57R of the front narrow width portion 57 can be positioned on the front side of the center in the front-rear direction L. The outer edges of the side slits 52 of the embodiment are linear extending in the front-rear direction L, and the inner edges of the side slits 52 are bent outward in the width direction W at the front narrow portion 57. Since the side slits 52 have the front narrow width portions 57, the length of the absorbent core 50 in the crotch region S3 that becomes shorter in the width direction W becomes shorter toward the front side when worn. That is, the length of the absorbent core 50 in the width direction W is easily secured in a certain region including the front end edges 52F of the side slits 52. The length of the absorbent core 50 in the width direction W on the urination port side can be secured, and leakage in the urination region can be suppressed.

The side slit 52 has a wide width portion 53. The wide portion 53 is located between the front narrow portion 57 and the rear narrow portion 58 of the side slit 52. In the wide portions 53, the outer edges and the inner edges of the side slits 52 are linear along the front-rear direction L, and the width of the side slits 52 is constant. The wide portion 53 may have a length in the width direction W that is equal to or greater than the length in the width direction W of the 2 nd region R2. The length of the wide portion 53 in the width direction W may be equal to or greater than the length of the 2 nd region R2 adjacent to the wide portion 53 in the extended state of the absorbent article 10 in the width direction W. At least a part of the wide portion 53 is disposed in the crotch region S3, but the entire region of the wide portion 53 in the front-rear direction L may be disposed in the crotch region S3. The center 53CL of the wide portion 53 in the front-rear direction L may be located on the front side of the center 10CL of the absorbent article 10 in the front-rear direction L and on the front side of the center of the crotch region S3 in the front-rear direction L. Since the width-directional length of the wide portion of the side slit 52 is equal to or greater than the width-directional length of the side region, the side slit 52 can be made to enter the inside in the width direction over the entire width-directional area of the side region. The absorbent core 50 is easily accommodated in the crotch by shortening the length of the absorbent body in the width direction, and the uncomfortable feeling during wearing can be suppressed.

The 3 rd region R3 may have a maximum length in the width direction W greater than that of the 1 st region R1. The 3 rd region R3 sandwiched by the deformation guide portions 54 can secure a length in the width direction W more than the 1 st region R1 sandwiched by the side slits 52, and the absorbent core 50 can cover a wide area of the body. The length of the absorbent core 50 in the width direction in the front region S1 can be secured, and leakage in the front region S1 can be suppressed.

The side slits 52 may be located widthwise inward of the outer side edge 50S of the absorbent core 50, not reaching the outer side edge 50S of the absorbent core 50. With this configuration, the absorbent is present on the outer side in the width direction W than the side slits 52. The body fluid diffused through the side slits 52 can be held by the absorbent material, and side leakage can be suppressed.

The rear edges 52R of the side slits 52 may be located in the crotch region S3, and the side slits 52 do not reach the rear region S2. With this configuration, the region in which the length of the absorbent body in the width direction W is short hardly reaches the back region S2, and the absorbent core 50 in the back region S2 can be brought into contact with the body with a large width, thereby suppressing leakage.

The deformation guide 54 may be located inward in the width direction than the outer side edge 50S of the absorbent core 50, without reaching the outer side edge 50S of the absorbent core 50. According to this configuration, the outer edge of the absorbent core 50 can be brought into surface-contact with the body without being deformed by the deformation guide 54. Thus, the leakage in the front side region S1 can be further suppressed. In the case where the deformation guide 54 is formed of a slit, an absorbent material is present at a position on the outer side in the width direction than the deformation guide 54. The body fluid diffused through the deformation guide 54 can be held by the absorbent material, and side leakage can be suppressed.

The absorbent article is pulled up toward the skin side by the contraction part 61 of the leakproof gathers when worn. The contracted portion 61 of the leakproof gathers can overlap the 2 nd region R2 in the thickness direction T in the extended state of the absorbent article. When worn, the absorbent core 50 is sandwiched between the legs, and a force directed inward in the width direction is applied to the absorbent core. At this time, the 2 nd region of the absorbent core 50 is pulled inward in the width direction and toward the skin surface side by contraction of the contraction portion 61. When a force directed inward in the width direction is applied during wearing, the 2 nd region R2 is pulled inward in the width direction (arrow a in fig. 4 a) and toward the skin surface side T1 of the 1 st region R1 (arrow B in fig. 4 a) from the outer side to the inner side in the width direction. Therefore, the 2 nd region R2 moves inward in the width direction W toward the skin surface side T1 of the 1 st region R1, and the length of the absorbent core 50 in the width direction is likely to be shorter. In the state shown in fig. 4 (a), the 2 nd region R2 moves further inward in the width direction W toward the skin surface side T1 of the 1 st region R1, and becomes the state shown in fig. 4 (b). In the state shown in fig. 4 (b), the 1 st region R1 and the 2 nd region R2 overlap in the thickness direction T, and the length of the absorber in the width direction becomes shorter.

The contracted portion 61 of the leakproof gather can overlap the deformation guide portion 54 in the thickness direction T in the extended state of the absorbent article. The deformation guide portion 54 is pulled toward the skin surface by the contraction of the contraction portion 61. The absorbent core 50 deforms in the thickness direction T using the deformation guide 54 as a base point, and the deformed portion can be arranged close to the body. Thus, the absorbent core 50 can be more conformable to the body and leakage can be inhibited.

The contracted portion 61 of the leak-proof gather may overlap a region on the rear side of the center in the front-rear direction L of the deformation guide portion 54, rather than a region on the front side of the center in the front-rear direction L of the deformation guide portion 54, in the extended state of the absorbent article. The region on the rear side of the center of the deformation guide portion 54 in the front-rear direction L is pulled up toward the skin surface side by contraction of the contraction portion 61, and is easily pulled along the body. On the other hand, the area on the front side of the center in the front-rear direction L of the deformation guide 54 is less likely to be pulled up toward the skin surface side by the contraction of the contraction portion 61, and is easily arranged to cover the body while maintaining a planar shape. By configuring the absorbent core 50 to cover the body, leakage can be inhibited.

The 1 st origin point 62a located more outward in the width direction W than the contracted portion 61 among the origin point 62 constituting the leakproof gathers 60 may overlap with the 2 nd region R2 in the thickness direction T in the extended state of the absorbent article. The 1 st base point portion 62a located on the outer side in the width direction W than the contraction portion 61 is pulled inward in the width direction W and toward the skin surface side T1 by contraction of the contraction portion 61.

In the extended state of the absorbent article shown in fig. 1, the inner edges of the contracted portions 61 of the leakproof gathers 60 may overlap the wide portions 53 of the side slits 52 in the thickness direction T. Since the contraction portion 61 overlaps the wide portion 53 in the thickness direction T, a force is generated to pull the wide portion 53 inward in the width direction W and toward the skin surface side T1. When a force is applied from the outside to the inside in the width direction during wearing, the 2 nd region R2 is easily pulled toward the skin surface side of the 1 st region R1 and toward the inside in the width direction as shown by an arrow B in fig. 4 (a). Therefore, the 2 nd region R2 moves inward in the width direction toward the skin surface side of the 1 st region R1, and the length of the absorbent core 50 in the width direction is likely to be shorter.

A leg elastic member 67 that contracts in the front-rear direction L may be provided at a position outside the 2 nd region R2 in the width direction. When the 2 nd region R2 is pulled up toward the skin surface side T1 by contraction of the leg hole elastic members 67 and a force is applied from the outer side to the inner side in the width direction during wearing, the 2 nd region R2 is easily moved toward the skin surface side T1 of the 1 st region R1 and toward the inner side in the width direction. Thus, the widthwise length of the absorbent core 50 is easily shortened.

On an imaginary line (for example, FL 1) extending in the width direction across the wide width portion 53, the length in the width direction W of the 2 nd region R2 may be larger than the length in the width direction W of the 1 st region R1. When the 2 nd region R2 moves inward in the width direction and the skin surface side T1 of the 1 st region R1, the 1 st region R1 overlaps with the 2 nd region R2, and the length in the width direction of the entire absorbent core 50 can be shortened. Since the 2 nd region R2 has a length in the width direction larger than the length in the width direction of the 1 st region R1, the 2 nd region R2 can be accommodated within the range in the width direction of the 1 st region R1, and the length in the width direction of the entire absorbent core 50 can be shortened. The virtual line FL1 is a line extending in the width direction and arranged to overlap the wide portion 53. The virtual line FL1 may overlap at least a part of the region from the front end edge to the rear end edge of the wide portion 53.

More preferably, the 2 nd region R2 may have a width-directional length of 1/2 or less of the width-directional length of the 1 st region R1 on the virtual line FL1 extending in the width direction across the wide portion 53. When the 2 nd region R2 moves inward in the width direction and toward the skin surface side of the 1 st region R1, the 2 nd region R2 overlaps the 1 st region R1. At this time, since the length of the 2 nd region R2 in the width direction is 1/2 or less of the length of the 1 st region R1 in the width direction, even if the entire 2 nd region R2 moves inward in the width direction and overlaps with the 1 st region R1, the 2 nd regions R2 can be suppressed from overlapping with each other. Thus, the increase in the thickness of the absorbent core 50 locally due to the overlapping of the 2 nd regions R2 with each other can be suppressed. Therefore, the pressure concentration due to the local increase in the thickness of the absorbent core 50 is less likely to occur, and deterioration in the wearing feeling can be suppressed.

The absorbent core 50 may have a necked portion 51 having a length in the width direction W smaller than the maximum width of the absorbent core 50. The region of the maximum width 50M of the absorbent core 50 is disposed across the front region S1 and the crotch region S3, and is disposed across the back region S2 and the crotch region S3. The neck region 51 of the absorbent core 50 may be disposed in the crotch region S3. Since the absorbent core 50 in the crotch region S3 sandwiched between the crotch of the wearer has a short length in the width direction W, the absorbent core 50 is easily accommodated in the crotch of the wearer, and discomfort during wearing can be suppressed. The center 51CL of the neckdown portion 51 in the front-rear direction L may be located on the front side than the center 10CL of the absorbent article 10 in the front-rear direction L. The effect of shortening the length of the absorbent body in the width direction W on the front side of the absorbent article 10 is easily obtained.

The wide portion 53 may be arranged in the front-rear direction L in a region where the constricted portion 51 is provided. By sandwiching the absorbent core 50 with the legs, the length of the absorbent core 50 in the width direction in the neckdown portion 51 is shortened by the deformation of the wide width portion 53. The absorbent core 50 can be more easily accommodated in the crotch, and the uncomfortable feeling during wearing can be suppressed.

Next, an absorbent article 10X according to embodiment 2 will be described. Hereinafter, in the description of embodiment 2, the same reference numerals are used for the same components as those of embodiment 1, and the description thereof is omitted. The absorbent article according to embodiment 2 is configured to be able to align the absorbent article in an appropriate position with respect to a wearer. In general, when an absorbent article is worn on a wearer of an adult who is in a bed-ridden state, a wearing assistant wears the absorbent article on the wearer in a state where the wearing assistant is not positioned on the front side of the wearer but positioned on the side surface side of the wearer. In a state where the wearer-assistant is positioned on the side surface of the wearer, it may be difficult to recognize the navel of the wearer and to align the absorbent article. Therefore, in the conventional absorbent article, the absorbent article may not be properly aligned with respect to the wearer.

In addition, when a belt-type absorbent article is worn by a wearer-assistant positioned on the side surface side of the wearer, for example, the abdomen of the wearer is covered with the front waistline region in a state where the rear waistline region is laid under the body of the wearer, and then the fastening tape positioned on the outer side in the width direction of the rear waistline region is pulled outward in the width direction, and the fastening tape is fastened to the front waistline region. At this time, the wearer may pull the fastening tape outward in the width direction, which may cause the position of the absorbent article in the width direction to shift. Even if the wearer corrects the shift in the width direction of the absorbent article, the absorbent article blocks the navel, and it may be difficult to position the wearer with respect to the navel. Therefore, in the conventional absorbent article, the absorbent article may not be properly aligned with respect to the wearer. The present invention has been made in view of the above problem, and is configured to align an absorbent article in an appropriate position with respect to a wearer.

Fig. 7 is a plan view of the absorbent article according to embodiment 2 as viewed from the non-skin surface side. Fig. 8 is a plan view of the absorbent core according to embodiment 2 as viewed from the skin surface side. Fig. 9 isbase:Sub>A cross-sectional view of the absorbent article according to embodiment 2 taken along the linebase:Sub>A-base:Sub>A shown in fig. 1. Fig. 10 is a view showing an absorbent body of the absorbent article according to embodiment 2, taken along the line B-B shown in fig. 1. The mode of wearing the absorbent article according to embodiment 2 on the wearer is the same as the mode shown in fig. 6 of embodiment 1.

The absorbent core according to embodiment 2 is provided with a front mark portion. The front mark portion is a mark for aligning with the groin of the wearer when the absorbent article is worn, and is visible from the skin surface side T1 and the non-skin surface side T2 of the absorbent article. The reference numeral portion of the present embodiment is formed in the absorbent core 50 and is constituted by the auxiliary slit 54. The auxiliary slit 54 is the same as the slit constituting the deformation guide portion in embodiment 1, and the same reference numerals are used.

The auxiliary slit 54 as the front mark portion is configured to be visible from the skin surface side T1 of the absorbent article through the skin-facing sheet 41, and configured to be visible from the non-skin surface side T2 of the absorbent article 10X through the non-skin-facing sheet 42. The term "visible" in the present invention means that a test subject having good vision (1.0 or more) in both eyes can see the object in a room (standard: 500 to 750 lx) illuminated with daylight color (4600 to 5400K (on) as a color temperature standard) at a distance of about 30 to 50 cm. The slit of embodiment 2 may have a pair of auxiliary slits 54, a pair of side slits 52, and a central slit 55. The side slits 52 constitute the crotch mark portion of the present invention.

As shown in fig. 8, the absorbent core 50 may have a 1 st region R1 sandwiched by the pair of side slits 52, a 2 nd region R2 located between the side slits 52 and the outer edge 50S of the absorbent core 50, a 3 rd region R3 sandwiched by the pair of auxiliary slits 54, and a 4 th region R4 located between the auxiliary slits 54 and the outer edge of the absorbent core 50. In fig. 8, the 1 st region R1, the 2 nd region R2, the 3 rd region R3, and the 4 th region R4 are shown with different hatching. The 2 nd regions R2 are located outside the respective side slits 52 in the width direction W, and are provided in pairs. The 1 st region R1 and the 2 nd region R2 are regions extending in the width direction W from the side slits 52, and a pair of the 3 rd regions R3 are provided outside the auxiliary slits 54 in the width direction W. The 3 rd region R3 and the 4 th region R4 are regions extending in the width direction W from the auxiliary slit 54.

The auxiliary slits 54 may be configured to deform the absorbent core 50 in the thickness direction T. The absorbent core 50 is configured to deform from the auxiliary slit 54 as a base point when a force is applied thereto, for example, during wearing. The auxiliary slits 54 may be positioned on the front side compared to the side slits 52, at least in the front side region S1. The front end edges 54F of the auxiliary slits 54 are disposed in the front side region S1, and the rear end edges 54R of the auxiliary slits 54 are disposed in the crotch region S3. At least a part of the auxiliary slit 54 extends toward the front side to the outside in the width direction W in the front side region S1.

The reference numeral portion in the present embodiment is constituted by the auxiliary slit 54, but the reference numeral portion is not limited thereto. The front mark portion may be configured to be visible from the skin-surface side T1 and the non-skin-surface side T2 of the absorbent article 10X, and may be configured by at least one of a low basis weight region in which the basis weight of the absorbent material of the absorbent core 50 is lower than the surroundings, a compressed portion in which the absorbent core 50 is compressed in the thickness direction T, a slit formed in the absorbent core 50, and a structure having a poor rigidity of the absorbent core 50.

The front mark portion of the present embodiment is constituted by the auxiliary slit 54 and is continuous with the side slit 52 constituting the crotch mark portion. The auxiliary slit 54 may be integrated with the side slit 52 or may be separated therefrom. The rear end edges 54R of the auxiliary slits 54 may be connected to the front end edges 52F of the side slits 52. The rear end edges 54R of the auxiliary slits 54 may be positioned on the front side with respect to the center in the front-rear direction L of the absorbent article 10X, and may be positioned on the front side with respect to the center in the front-rear direction L of the absorbent core 50.

The auxiliary slit 54 constituting the front mark portion extends outward in the width direction W toward the front side and is disposed along the groin portion of the wearer. The groin portion is difficult to be shielded by clothing or an absorbent article during wearing, and is easily seen by a wearer assistant positioned on the side of the wearer. Therefore, the auxiliary slit 54 can be aligned with the groin of the wearer when worn, and the absorbent article 10X can be aligned at an appropriate position. After the absorbent article 10X is worn, the auxiliary slit 54 can be recognized from the non-skin surface side T2, and it can be confirmed whether or not the auxiliary slit 54 is at a position corresponding to the groin. Therefore, the wearing assistant can grasp whether or not the absorbent article is worn at the correct position from the non-skin surface side of the absorbent article.

Further, since the front mark portion is the auxiliary slit 54, the absorbent core 50 is easily deformed from the auxiliary slit 54 as a base point when worn. Therefore, the auxiliary slit 54 can be aligned with the inguinal portion, and the auxiliary slit 54 can be disposed along the inguinal portion. Thus, the absorbent article can be aligned in position, and the absorbent core 50 can be arranged along the groin portion. As shown in fig. 6, the absorbent core 50 is deformed with the auxiliary slits 54 as base points, and wrinkles are generated around the auxiliary slits 54 on the skin surface and the non-skin surface of the absorbent article 10X. The wrinkles become marks, and the auxiliary slit 54 is more easily arranged in the groin.

The front region S1 of the absorbent article 10X is deformed from the auxiliary slit 54 as a base point. The auxiliary slit 54 extends forward and outward in the width direction and is deformed to follow the groin portion. The 3 rd region R3 between the auxiliary slits 54 covers the bulge of the body between the inguinal regions, and the 3 rd region R3 is curved toward the skin surface side T1 from the 4 th region R4 on the outer side in the width direction W than the auxiliary slits 54. In a cross section of the front region S1 along the width direction W, the front region is deformed into a curved shape so as to cover the body.

As shown in fig. 10, the skin sheet 41 is joined to the non-skin sheet 42 in the region overlapping the auxiliary slit 54. In the present embodiment, the core wrap sheet 56 as the skin-facing sheet 41 and the core wrap sheet 56 as the non-skin-facing sheet 42 are joined to each other in a region overlapping the auxiliary slit 54. When the skin sheet 41 and the non-skin sheet 42 are joined, the auxiliary slit 54 is in close contact with the skin sheet 41 and the non-skin sheet 42, and the visibility of the auxiliary slit 54 is improved. Since the visibility of the front mark portion is improved, it is easier to align the absorbent article at an appropriate position.

In order to improve the visibility of the auxiliary slits 54, the inner and outer edges of the auxiliary slits 54 may be pressed in the thickness direction T. By performing the press working on the inner edge and the outer edge of the auxiliary slit 54, the visibility of the edge of the auxiliary slit 54 is improved, and the visibility of the front mark portion can be improved.

The absorbent core 50 may have a crotch indicium. The crotch mark portion is a mark for aligning with the crotch of the wearer when the absorbent article is worn, and is visible from the skin surface side T1 and the non-skin surface side T2 of the absorbent article. The crotch mark portion of the present embodiment is formed in the absorbent core 50 and is constituted by the side slits 52. The side slits 52 as the crotch mark portions are configured to be visible from the skin-surface side T1 of the absorbent article 10X through the skin-sheet 41, and configured to be visible from the non-skin-surface side T2 of the absorbent article 10X through the non-skin-sheet 42.

The crotch mark portion of the present embodiment is constituted by the side slits 52, but the crotch mark portion is not limited thereto. The crotch mark portion may be configured to be visible from the skin surface side T1 and the non-skin surface side T2 of the absorbent article 10X, and may be configured by at least one of a low basis weight region in which the basis weight of the absorbent material of the absorbent core 50 is lower than the surrounding, a compressed portion in which the absorbent core 50 is compressed in the thickness direction T, a slit formed in the absorbent core 50, and a poor rigidity structure of the absorbent core 50.

The side slits 52 may be disposed at least in the crotch region S3. The front edges 52F of the side slits 52 can be disposed in the crotch region S3, and the rear edges 52R of the side slits 52 can be disposed in the crotch region S3. The side slits 52 may extend at least in the front-rear direction L, and may be along the front-rear direction L or may have a portion inclined with respect to the front-rear direction L. The length of the side slit 52 in the width direction W may be constant or may vary. The side slits 52 may not be provided at the center of the width direction W of the absorbent core 50, but a pair may be provided symmetrically with respect to the center of the width direction W of the absorbent core 50.

By providing the side slits 52 in the absorbent core 50, the side slits 52 can be positioned with respect to the body at a position closer to the crotch than the inguinal portions. The side slits 52 extend in the front-rear direction L, and facilitate the disposition of the crotch region S3 along the front-rear direction L of the body when worn. After wearing, it can be grasped whether or not the crotch region S3 is accurately disposed from the non-skin surface side T2 of the absorbent article 10X. The auxiliary slit 54 extends outward in the width direction W, and the side slit 52 extends in the front-rear direction L. Since the auxiliary slits 54 and the side slits 52 extend in different directions, the boundary therebetween is easily conspicuous. Therefore, the region to be disposed along the groin portion can be easily grasped, and the absorbent article 10X can be more easily aligned to an appropriate position.

Further, since the crotch mark portion is the side slits 52, the absorbent core 50 is easily deformed from the side slits 52 as a base point during wearing. Specifically, in the state where the absorbent article 10X is worn, the absorbent article 10X is sandwiched between the legs, and a force directed inward in the width direction W is applied to the crotch region S3 by the legs. When a force directed inward in the width direction W is applied to the absorber in the crotch region S3, the side slits 52 of the absorbent core 50 deform, the 2 nd region R2 moves inward in the width direction W, and the length of the absorbent core 50 in the width direction W becomes shorter. The absorbent core 50 can enter the inside in the width direction through the side slits 52 in the crotch region S3. Since the length of the absorbent core 50 in the width direction in the crotch region S3 is short, the absorbent core 50 is easily accommodated in the crotch, and discomfort during wearing can be suppressed. Therefore, the crotch region S3 can be positioned with respect to the crotch via the side slits 52, and can be disposed in the region between the legs. Thus, the absorbent article can be aligned in position, and the absorbent core can be arranged in a more desirable compact state.

As shown in fig. 9, the skin sheet 41 may be joined to the non-skin sheet 42 in the region overlapping the side slits 52. In the present embodiment, the core wrap sheet 56 as the skin-facing sheet 41 and the core wrap sheet 56 as the non-skin-facing sheet 42 are joined to each other in a region overlapping with the side slits 52. When the skin sheet 41 is joined to the non-skin sheet 42, the side slits 52 are in close contact with the skin sheet 41 and the non-skin sheet 42, and the visibility of the side slits 52 is improved. By improving visibility of the side slits 52, it is easier to align the absorbent article in position.

In order to improve the visibility of the side slits 52, the inner and outer edges of the side slits 52 may be pressed in the thickness direction T. By performing the press working on the inner and outer edges of the side slits 52, the visibility of the edges of the side slits 52 can be improved, and the visibility of the crotch mark portion can be improved.

The width of the auxiliary slits 54 may be smaller than the width of the side slits 52. The width of the side slits 52 is the length in the direction orthogonal to the longitudinal direction of the side slits 52, and the side slits 52 extending in the front-rear direction L are the length in the width direction. Similarly, the width of the auxiliary slit 54 is the length in the direction orthogonal to the longitudinal direction of the auxiliary slit 54, and the auxiliary slit 54 extending in the front-rear direction L is the length in the width direction. In the case of the side slit 52 and the auxiliary slit 54 being integrated, the boundary between the side slit 52 and the auxiliary slit 54 may be a portion having a varying width. In the configuration in which the width of the side slits 52 and the width of the auxiliary slits 54 are changed, the maximum width of the auxiliary slits 54 may be smaller than the maximum width of the side slits 52, or the average width of the auxiliary slits 54 may be smaller than the average width of the side slits 52.

The auxiliary slit 54 is a mark for positioning with respect to the inguinal portion in the front region S1, and is easier to see than the side slit 52 provided in the crotch region S3. Therefore, even if the width of the auxiliary slit 54 is smaller than the width of the side slit 52, the function of the front mark portion is easily exhibited. Further, by making the width of the auxiliary slit 54 different from the width of the side slit 52, the wearer can easily distinguish between the auxiliary slit 54 and the side slit 52. The boundary between the auxiliary slit 54 and the side slit 52 is easy to grasp, the region to be arranged along the inguinal portion is easy to grasp, and the absorbent article 10X is easier to be aligned to an appropriate position.

If the length of the auxiliary slit 54 in the width direction is too long, the length of the portion of the absorbent core 50 deformed in the width direction becomes long, and the length of the portion of the absorbent core 50 disposed along the body becomes short, which may cause leakage in the front region S1. However, since the width of the auxiliary slits 54 is smaller than the width of the side slits 52, the length of the absorbent core 50 in the width direction in the front region S1 can be secured, and leakage in the front region S1 can be suppressed. As shown in fig. 6, leakage in the front side region S1 can be suppressed, and the absorbent core 50 can be fitted along the groin portions of the wearer.

In order to further obtain an effect that the wearer can fit the wearer along the groin while suppressing discomfort in the crotch region S3 and leakage in the front region S1, the width of the auxiliary slit 54 may be 1/2 or less of the width of the side slit 52. The distance of inward movement in the width direction obtained by the side slits 52 can be secured, and the distance of inward movement in the width direction in the front region S1 can be suppressed.

The center slit 55 may be located between the side slits 52 in the width direction W and extend in the front-rear direction L. The central slit 55 may be separated from the side slits 52 in the width direction and the auxiliary slits 54 in the width direction. At least a portion of the central slit 55 may be disposed in the crotch region S3. The front edge 55F of the central slit 55 is disposed in the crotch region S3, and the rear edge 55R of the central slit 55 is disposed in the rear region S2. The central slit 55 may be located more to the rear side than the side slits 52, and the front end edge of the central slit 55 may be located more to the rear side than the front end edge 52F of the side slits 52. The center slit 55 may extend at least in the front-rear direction L, and may be along the front-rear direction L or may have a portion inclined with respect to the front-rear direction L.

The 1 st region R1 is easily bent in the thickness direction T by the central slit 55, and the length in the width direction of the entire absorber can be further shortened. More specifically, when a force is applied from the outside toward the inside in the width direction during wearing, the absorbent core 50 is easily deformed so that the inside edge of the 1 st region R1 faces the skin surface side, with the outside edge (side slit 52) of the 1 st region R1 as the starting point. Thus, the widthwise length of the absorbent core 50 is easily made shorter. The absorbent core 50 in the crotch region S3 may be deformed into a convex shape having the center in the width direction of the absorbent core 50 as the apex, and the length in the width direction of the entire absorbent core 50 can be further shortened.

In addition, when the absorbent article 10X is used, an absorbent pad may be used by being placed on the skin surface side of the absorbent article 10X. At this time, in the crotch region S3, the 2 nd region R2 of the absorbent core 50 moves to the skin surface side T1 of the 1 st region R1, and the skin surface of the absorbent core 50 is pushed up toward the wearer, so that the absorbent pad can be disposed close to the skin surface. The absorbent pad can be fitted to the body, and leakage can be further suppressed. In the front side region S1, the 4 th region R4 is deformed to rise toward the skin surface side with respect to the 3 rd region R3 with the auxiliary slit 54 as a base point. By disposing the absorbent pad in the 3 rd region, the outer edge of the absorbent pad can be held between the 4 th region. In this way, the absorbent core 50 deforms along the groin portions while holding the absorbent pad, and therefore the absorbent pad can be disposed along the region between the groin portions.

The 3 rd region R3 may have a maximum length in the width direction W greater than that of the 1 st region R1. The 3 rd region R3 sandwiched by the auxiliary slits 54 can secure a length in the width direction W more than the 1 st region R1 sandwiched by the side slits 52, and can cover the body with the absorbent core 50 over a wide range. The length of the absorbent core 50 in the width direction in the front region S1 can be secured, and leakage in the front region S1 can be suppressed.

The side slits 52 may be located widthwise inward of the outer side edge 50S of the absorbent core 50, not reaching the outer side edge 50S of the absorbent core 50. With this configuration, the absorbent is present outside the side slits 52 in the width direction W. The body fluid diffused through the side slits 52 can be retained by the absorbent material, and side leakage can be suppressed.

The rear edges 52R of the side slits 52 may be located in the crotch region S3, and the side slits 52 do not reach the rear region S2. With this configuration, the region in which the length of the absorbent body in the width direction W is short hardly reaches the back region S2, and the absorbent core 50 in the back region S2 is in wide contact with the body, thereby suppressing leakage.

The auxiliary slits 54 may be located widthwise inward of the outer side edge 50S of the absorbent core 50, not reaching the outer side edge 50S of the absorbent core 50. According to this configuration, the outer edge of the absorbent core 50 can be brought into surface contact with the body without being deformed by the auxiliary slits 54. Thus, the leakage in the front side region S1 can be further suppressed. In the case where the auxiliary slits 54 are slits, the absorbent material is present at positions outside the auxiliary slits 54 in the width direction. The body fluid diffused through the auxiliary slit 54 can be retained by the absorbent material, and side leakage can be suppressed.

A leg elastic member 67 that contracts in the front-rear direction L may be provided at a position outside the 2 nd region R2 in the width direction. When the 2 nd region R2 is pulled up toward the skin surface side T1 by contraction of the leg hole elastic members 67 and a force is applied from the outer side toward the inner side in the width direction during wearing, the 2 nd region R2 easily moves toward the skin surface side T1 of the 1 st region R1 and the inner side in the width direction. Thus, the widthwise length of the absorbent core 50 is easily shortened.

The absorbent core 50 may have a neckdown portion 51 having a length in the width direction W smaller than the maximum width of the absorbent core 50. The region of the maximum width 50M of the absorbent core 50 is disposed across the front region S1 and the crotch region S3, and across the back region S2 and the crotch region S3. The neck region 51 of the absorbent core 50 may be disposed in the crotch region S3. Since the length of the absorbent core 50 in the width direction W of the crotch region S3 sandwiched between the wearer 'S crotch is short, the absorbent core 50 is easily accommodated in the wearer' S crotch, and discomfort during wearing can be suppressed. The center 51CL of the neckdown portion 51 in the front-rear direction L may be located on the front side than the center 10CL of the absorbent article 10X in the front-rear direction L. The effect of shortening the length of the absorber in the width direction W on the front side of the absorbent article 10X is easily obtained.

The non-skin surface sheet may have printed portions 81 and 82 that can be seen from the non-skin surface side T2 of the absorbent article. The printing portion may have a 1 st printing portion 81 overlapping the outer edge of the auxiliary slit 54 and a 2 nd printing portion 82 overlapping the outer edge of the side slit 52. The printed portion may be configured to be visible from the non-skin surface side T2 of the absorbent article. The printed portion of the present embodiment is provided on the back film 42a and configured to be visible through the exterior sheet 42b. The wearer can easily grasp the auxiliary slit 54 by the 1 st printing portion 81 and easily recognize the side slit 52 by the 2 nd printing portion 82. The boundary between the auxiliary slit 54 and the side slit 52 is easily grasped, the region to be arranged along the inguinal portion is easily grasped, and the absorbent article is more easily aligned to an appropriate position.

The 1 st printing portion 81 and the 2 nd printing portion 82 may be provided over the entire region in the front-rear direction of the absorbent article, over the entire region in the front-rear direction of the absorbent core, or only over the region overlapping the auxiliary slit 54 and the side slit 52. The 1 st printing portion 81 and the 2 nd printing portion 82 of the present embodiment are provided in the front-rear direction over the entire region in the front-rear direction of the absorbent article. The 1 st printing unit 81 and the 2 nd printing unit 82 are preferably separated in the width direction in order to be easily distinguished from each other.

The embossed portion 45 may be formed on the outer sheet 42b other than the skin-facing sheet. The embossed portion 45 is a portion obtained by compressing the exterior sheet 42b in the thickness direction T. The embossed portion 45 may be disposed at least in a region overlapping with the auxiliary slit 54. The thickness of the non-skin surface sheet is reduced by the embossing portion. Therefore, visibility of the auxiliary slit 54 from the non-skin surface side of the absorbent article can be improved. The thickness of the non-skin surface sheet 42 is made thin by the embossing portion 45. Therefore, the visibility of the auxiliary slit 54 from the non-skin surface side T2 of the absorbent article 10X can be improved. The embossed portion 45 may overlap the side slit 52. The visibility of the side slit 52 from the non-skin surface side T2 of the absorbent article 10X can be improved.

The embossed portion 45 may be provided over the entire area of the exterior sheet 42b, may be provided over the entire area overlapping the absorbent core 50, or may be provided only over the area overlapping the auxiliary slit 54 and the side slit 52. The embossed portion 45 of the present embodiment is formed in a lattice shape over the entire area of the outer sheet 42b.
