[0010] The present specification and the accompanying drawings will make clear at least the following aspects [1] to

[12] .

[0011] [1] A pants-type absorbent article comprising a main body having an outer body and an inner body fixed to the inside of the outer body, wherein the main body has a structure in which a ventral region located on the ventral side of a wearer when worn, a dorsal region located on the dorsal side of the wearer when worn, and a crotch region located between the ventral region and the dorsal region are arranged along the longitudinal direction, the outer body has a waist opening through which the wearer's torso is passed, and a pair of leg openings through which both legs of the wearer are passed, the inner body has a liquid-permeable top sheet located on the skin side of the wearer when worn, a liquid-impermeable back sheet located on the non-skin side of the wearer when worn, and an absorbent body disposed between the top sheet and the back sheet and having an absorbent core for absorbing the wearer's bodily waste, a pants-type absorbent article in which, in a folded state in which the main body portion is folded in half along a fold point extending parallel to a width direction perpendicular to the longitudinal direction, a first width which is the width of the absorbent core along the end of the crotch region in the longitudinal direction is equal to or greater than a second width which is the width of the inner body along the fold point, and a portion of the absorbent core included in the crotch region is provided with a pair of recesses on both sides of a center line which passes through the center of the absorbent body in the width direction and is parallel to the longitudinal direction, the recesses respectively extending in the longitudinal direction and making the thickness of the absorbent core in the thickness direction perpendicular to the longitudinal direction and the width direction smaller than that of the surrounding area.

[0012] In the above-described pant-type absorbent article, the absorbent core is formed wide so that the relationship "first width ≥ second width" is satisfied in the folded state. Furthermore, when the pant-type absorbent article is folded in half, such as when the pant-type absorbent article is removed from a package (wrapped body), the user can easily recognize by sight and touch that the absorbent core in the crotch region is wide. That is, the user can recognize that the portion of the absorbent core near the end of the crotch region (i.e., the folded end of the crotch region located at the lowest end, if the end of the waist opening is considered to be the upper end before the pant-type absorbent article is folded) has a sufficient width compared to the portion near the folding origin of the inner body. This gives the user a sense of expectation that the wide absorbent core will effectively prevent leakage of body exudates. Furthermore, when it is confirmed that no side leakage of body exudates occurs after use of the pant-type absorbent article, a sense of security regarding the pant-type absorbent article (in other words, a sense of trust in the pant-type absorbent article based on the realization that the previously expected effects as described above have actually been achieved) can be favorably fostered. Furthermore, the absorbent core is provided with a pair of longitudinally extending recesses on both sides of the centerline. This allows the absorbent core to be deformed starting from the pair of recesses, thereby reducing the discomfort that a wearer may experience when wearing the absorbent core due to the widened absorbent core. Therefore, the pants-type absorbent article can improve comfort and security for the user when worn.

[0013] [2] A pants-type absorbent article according to [1], wherein in the folded state, the first width is equal to or greater than a first length, which is the length from the folding point in the longitudinal direction to the end of the waist opening.

[0014] [3] A pants-type absorbent article according to [1] or [2], wherein in the folded state, the first width is equal to or greater than a second length, which is the length from the fold origin to the end of the crotch region in the longitudinal direction.

[0015] [4] A pants-type absorbent article according to any one of [1] to [3], wherein in the folded state, the first width is equal to or greater than a third length, which is the widthwise length of the end portion of the inner body in the longitudinal direction.

[0016] [5] A pants-type absorbent article according to any one of [1] to [4], wherein in the folded state, the first width is equal to or greater than a fourth length, which is the length of the ventral region and the dorsal region in the longitudinal direction.

[0017] According to each of the configurations [2] to [5] above, the user can be more effectively made aware that the absorbent core is wide when folded, thereby more effectively fostering a sense of security in the user regarding prevention of side leakage.

[0018] [6] A pants-type absorbent article according to any one of [1] to [5], wherein the pair of recesses are arranged so as not to overlap with an elastic member provided to stretch the main body portion in the width direction.

[0019] According to the above-mentioned configuration [6], by not overlapping the part of the absorbent core that is particularly susceptible to deformation in the crotch region (i.e., the part where the pair of recesses is provided) with the elastic member that expands and contracts in the width direction, it is possible to prevent the part of the absorbent core that is particularly susceptible to deformation in the width direction. This makes it possible to preferably maintain the wide state of the part of the absorbent core included in the crotch region in the folded state. As a result, it is possible to more effectively make the user aware of the wideness of the absorbent core.

[0020] [7] A pants-type absorbent article according to any one of [1] to [6], wherein the absorbent core has a portion in the crotch region that extends outward in the width direction beyond the outer body.

[0021] According to the configuration [7] above, by forming the absorbent core in the crotch region to be wide enough to extend outward in the width direction beyond the outer body, the user can be more effectively made aware of the wide absorbent core when in the folded state.

[0022] [8] A pants-type absorbent article according to [7], wherein the portion of the absorbent core that extends outward in the width direction beyond the outer body in the crotch region is positioned opposite the wearer's gracilis muscle when worn.

[0023] According to the configuration [8] above, the absorbent core is formed to be wide so as to cover the area where a gap is likely to occur between the wearer and the pants-type absorbent article when the thighs become thinner due to a decrease in muscle thickness caused by aging (i.e., the area corresponding to the wearer's gracilis muscle), thereby more effectively improving the user's sense of security.

[0024] [9] A pants-type absorbent article according to [7] or [8], wherein the absorbent body extends outward in the width direction beyond the outer body in the crotch region, and the non-skin-facing portion of the part where the absorbent core is arranged is colored a different color from the outer body.

[0025] According to the above-mentioned configuration [9], the portion including the widthwise end of the absorbent core formed wide in the crotch region (i.e., the colored portion) can be easily visually recognized from the non-skin-facing side, thereby making it possible to more effectively make the user aware of the wide absorbent core in the folded state.

[0026]

[10] A pants-type absorbent article according to any one of [1] to [9], wherein at least one of the entire non-skin-facing portion of the absorbent body where the absorbent core is located and the outer casing is colored so that the entire non-skin-facing portion of the absorbent body where the absorbent core is located and the outer casing are colored differently.

[0027] According to the configuration

[10] above, by emphasizing the contrast (color difference) between the absorbent body (absorbent core) and the outer casing, it is possible to make it easier to visually grasp the position of the absorbent core.

[0028]

[11] A package for accommodating a plurality of pants-type absorbent articles, wherein each of the plurality of pants-type absorbent articles has a main body portion having an outer body and an inner body fixed to the inside of the outer body, wherein the main body portion has a structure in which a ventral region located on the ventral side of a wearer when worn, a dorsal region located on the dorsal side of the wearer when worn, and a crotch region located between the ventral region and the dorsal region are arranged along the longitudinal direction, wherein the outer body has a waist opening through which the torso of the wearer is passed and a pair of leg openings through which both legs of the wearer are passed, and wherein the inner body has a liquid-permeable top sheet located on the skin side of the wearer when worn, a liquid-impermeable back sheet located on the non-skin side of the wearer when worn, and an absorbent body disposed between the top sheet and the back sheet and having an absorbent core for absorbing excrement of the wearer, Each of the plurality of pants is stored in a folded state in which the main body portion is folded in half along a fold point extending parallel to a width direction perpendicular to the longitudinal direction, and in the folded state, a first width, which is the width of the absorbent core along the end of the crotch region in the longitudinal direction, is equal to or greater than a fourth width, which is the width of the main body portion along the fold point, and is equal to or greater than a third width, which is the width of the end of the waist opening.

[0029] In the above-mentioned package, a plurality of pant-type absorbent articles are stored in a folded state, and each pant-type absorbent article satisfies the relationships "first width ≧ fourth width" and "first width ≧ third width" when folded. This allows a user to easily recognize by sight and touch that the absorbent core in the crotch region is wide when the pant-type absorbent article is folded in half when removing the pant-type absorbent article from the package. This gives the user a sense of expectation that the wide absorbent core will effectively prevent leakage of body exudates. Furthermore, when it is confirmed that no side leakage of body exudates occurs after use of the pant-type absorbent article, this can favorably foster a sense of security regarding the pant-type absorbent article (in other words, a sense of trust in the pant-type absorbent article based on the realization that the expected effects have actually been achieved). Therefore, the above-mentioned package can improve the user's sense of security.

[0030]

[12] The package of

[11] , wherein in the folded state, the first width is 1.5 times or more the third width.

[0031] According to the configuration

[12] above, in the folded state, the visibility of the wide portion of the absorbent core in the crotch region can be more effectively improved, thereby more suitably improving the sense of security of the user.

[0032] [Embodiments] Hereinafter, embodiments of the present disclosure will be described in detail with reference to the drawings. In the following description, the same or equivalent elements will be designated by the same reference numerals, and duplicate explanations will be omitted. The drawings may be partially simplified or exaggerated for ease of understanding, and the dimensional proportions are not limited to those shown in the drawings.

[0033] A pants-type absorbent article 1 according to one embodiment will now be described. Fig. 1 is a perspective view of the pants-type absorbent article 1. Fig. 2 is a plan view of the pants-type absorbent article 1 as viewed from the non-skin-facing side Z2, and Fig. 3 is a plan view of the pants-type absorbent article 1 as viewed from the skin-facing side Z1. Fig. 4 is a schematic diagram of the cross-sectional structure taken along line IV-IV in Fig. 3. Figs. 5(A) and 5(B) are schematic diagrams of the cross-sectional structure taken along line VV in Fig. 3. Fig. 5(A) schematically shows a state in which leakage-preventing gathers 25, which will be described later, are erected, and Fig. 5(B) schematically shows a state in which the leakage-preventing gathers 25 are laid inward to the maximum extent.

[0034] In the following description, a "wearer" refers to a person who wears the pants-type absorbent article 1. The "skin-facing side" is the side that faces the wearer's skin when the pants-type absorbent article 1 is worn by the wearer (hereinafter referred to as the "worn state"). The "non-skin-facing side" is the side that faces away from the wearer's skin when worn. The "user" of the pants-type absorbent article 1 includes the wearer described above, as well as a helper (caregiver / caregiver) who raises or cares for the wearer, who is a child or a care recipient.

[0035] As shown in Fig. 1, as an example, the pants-type absorbent article 1 is a pants-type disposable diaper that absorbs urine and other body waste from a wearer. That is, the pants-type absorbent article 1 has a waist opening H1 through which the wearer's torso is passed and a pair of leg openings H2 through which the wearer's legs are passed (Fig. 1 shows the leg opening H2 through which the left leg is passed). The pants-type absorbent article 1 is composed of a main body 50 having an outer body 10 that faces outward (non-skin-facing side Z2) when worn, and an inner body 20 fixed to the inside of the outer body 10. The pants-type absorbent article 1 is configured to be cut by tearing a pair of side seal portions 10a of the outer body 10 provided on both the left and right sides of the wearer.

[0036] 2 and 3 show the pants-type absorbent article 1 in an unfolded state in which the outer casing 10 is cut along a pair of side seal portions 10a and the pants-type absorbent article 1 is stretched to a state in which no wrinkles are formed. In the following description, unless otherwise specified, the shape and positional relationship of each part of the pants-type absorbent article 1 in the unfolded state will be described.

[0037] In the unfolded state, the pants-type absorbent article 1 (main body portion 50) extends in the width direction X and the longitudinal direction Y. The longitudinal direction Y is the direction in which the ventral region 1a, the crotch region 1c, and the back region 1b are aligned. In the unfolded state, the longitudinal direction Y is the direction in which the ventral region 1a and the back region 1b face each other with the crotch region 1c in between. The width direction X is a direction perpendicular to the longitudinal direction Y, and corresponds to the left-right direction of the wearer when worn. The thickness direction Z is a direction perpendicular to both the width direction X and the longitudinal direction Y, and is the direction in which the outer body 10 and the inner body 20 overlap each other. In the following description, the side of the pants-type absorbent article 1 in the longitudinal direction Y where the ventral region 1a is located may be simply referred to as the "ventral side," and the side in the longitudinal direction Y where the back region 1b is located may be simply referred to as the "dorsal side."

[0038] In this embodiment, the ventral region 1a is defined as a portion of the pant-type absorbent article 1 in the unfolded state (see FIGS. 2 and 3) that is included in the range from the ventral end 10b of the exterior body 10 to the dorsal end of the ventral side seal portion 10a. Similarly, the dorsal region 1b is defined as a portion of the pant-type absorbent article 1 in the unfolded state that is included in the range from the dorsal end 10c of the exterior body 10 to the dorsal end of the dorsal side seal portion 10a.

[0039] (Configuration of the Exterior Body) As shown in FIGS. 2 to 4 , the exterior body 10 includes a main body sheet 11, a ventral-side sheet 12, and a dorsal-side sheet 13. As an example, the main body sheet 11 is a sheet member that defines the overall outer shape of the exterior body 10 when viewed in the thickness direction Z (in this embodiment, as an example, an hourglass shape). However, the configuration of the main body sheet 11 is not limited to the above. For example, the main body sheet 11 may have a so-called three-piece configuration, including two sheet members corresponding to the ventral side and the dorsal side, and a sheet member disposed on the non-skin-facing side Z2 of the interior body 20. The ventral-side sheet 12 is disposed so as to overlap the main body sheet 11 in the ventral region 1a. The dorsal-side sheet 13 is disposed so as to overlap the main body sheet 11 in the dorsal region 1b. The main body sheet 11 is formed of, for example, an SMS nonwoven fabric. The ventral-side sheet 12 and the dorsal-side sheet 13 are formed of, for example, a spunbond nonwoven fabric.

[0040] The ventral-side sheet 12 is folded back so as to sandwich the ventral end 11a of the main body sheet 11. That is, the ventral-side sheet 12 has an inner portion 121 located inside the main body sheet 11 (skin-facing side Z1) and an outer portion 122 located outside the main body sheet 11 (non-skin-facing side Z2).

[0041] The end 121 a of the folded inner portion 121 is located on the dorsal side of the ventral end 20 a of the inner body 20 and on the ventral side of the ventral end 31 a of the absorbent core 31 contained in the inner body 20 .

[0042] The end 122a of the folded outer portion 122 is positioned further toward the back than the end 121a of the inner portion 121. A plurality of (19 in this embodiment) abdominal elastic members 14 are arranged along the longitudinal direction Y between the outer portion 122 and the main body sheet 11 in the abdominal region 1a. As shown in Fig. 2, each abdominal elastic member 14 extends parallel to the width direction X between the edges 1d in the width direction X of the abdominal region 1a of the pants-type absorbent article 1. Therefore, the abdominal waist portion of the exterior body 10 stretches in the width direction X while fitting around the waist of the wearer. The plurality of abdominal elastic members 14 are made of an elastic material such as rubber thread or spandex.

[0043] The back-side sheet 13 is folded back so as to sandwich the back-side end 11b of the main body sheet 11. That is, the back-side sheet 13 has an inner portion 131 located inside the main body sheet 11 (skin-facing side Z1) and an outer portion 132 located outside the main body sheet 11 (non-skin-facing side Z2).

[0044] The end 131 a of the folded inner portion 131 is located on the ventral side of the dorsal end 20 b of the inner body 20 and on the dorsal side of the dorsal end 31 b of the absorbent core 31 contained in the inner body 20 .

[0045] The end 132a of the folded outer portion 132 is positioned closer to the ventral side than the end 131a of the inner portion 131. A plurality of (fifteen in this embodiment) back stretchable members 15 are arranged along the longitudinal direction Y between the outer portion 132 and the main body sheet 11 in the back region 1b. As shown in FIG. 2 , each back stretchable member 15 extends parallel to the width direction X between the edges 1e in the width direction X of the back region 1b of the pants-type absorbent article 1. Therefore, like the ventral waist portion provided with the above-mentioned abdominal stretchable members 14, the back waist portion of the outer body 10 also stretches in the width direction X while fitting to the waist of the wearer. The plurality of back stretchable members 15 are made of an elastic material such as rubber thread or spandex.

[0046] Between the outer portion 132 and the main body sheet 11, a plurality of (three in this embodiment) leg-hole elastic members 16 are arranged along the longitudinal direction Y, closer to the ventral side than the plurality of back-hole elastic members 15. As shown in Fig. 2, each leg-hole elastic member 16 extends in the width direction X between the edges 1e of the back region 1b of the pants-type absorbent article 1, and includes a portion that extends in a curved shape along the edge of the back portion of each of the pair of leg openings H2. The plurality of leg-hole elastic members 16 allow the outer body 10 to stretch to fit the wearer's legs. The plurality of leg-hole elastic members 16 are made of an elastic material, such as rubber thread or spandex.

[0047] The inner portion 121 of the ventral sheet 12 and the inner body 20 are bonded to each other by a hot melt adhesive (not shown) arranged between the inner portion 121 and the inner body 20. The outer portion 122 of the ventral sheet 12 and the main body sheet 11 are bonded to each other by a hot melt adhesive (not shown) arranged between the outer portion 122 and the main body sheet 11, so as to sandwich the plurality of abdominal elastic members 14. Similarly, the inner portion 131 of the back sheet 13 and the inner body 20 are bonded to each other by a hot melt adhesive (not shown) arranged between the inner portion 131 and the inner body 20. The outer portion 132 of the back sheet 13 and the main body sheet 11 are bonded to each other by a hot melt adhesive (not shown) arranged between the outer portion 132 and the main body sheet 11, so as to sandwich the plurality of spine elastic members 15 and the plurality of leg elastic members 16. Furthermore, the main body sheet 11 and the inner body 20 are bonded to each other by a hot melt adhesive (not shown) that is disposed between the main body sheet 11 and the inner body 20 (back sheet 22). By joining the various components together as described above, the pants-type absorbent article 1 has a configuration in which the outer body 10 and the inner body 20 are integrally joined.

[0048] 2, 3, and 5, the inner body 20 has a rectangular shape that extends in the longitudinal direction Y and the width direction X when viewed in the thickness direction Z, with the length in the longitudinal direction Y being longer than the length in the width direction X. The inner body 20 has a topsheet 21, a backsheet 22, an absorbent body 23, and a pair of side sheets 24.

[0049] The topsheet 21 is located on the skin-facing side Z1 of the wearer when worn and forms the surface that comes into contact with the wearer's skin. The topsheet 21 is made of a liquid-permeable (water-permeable) nonwoven fabric such as a spunbond nonwoven fabric, and covers the skin-facing side Z1 of the absorbent body 23. Typically, the topsheet 21 is plain white. The topsheet 21 is adhered to the skin-facing side Z1 surface of the absorbent body 23 (white tissue 32, described below) with, for example, a hot melt adhesive (not shown).

[0050] The back sheet 22 is a sheet that is positioned on the non-skin-facing side Z2 of the wearer when the garment is worn. Specifically, the back sheet 22 is positioned on the opposite side of the top sheet 21 with the absorbent body 23 in between. The back sheet 22 is made of, for example, a liquid-impermeable (water-impermeable) film, and covers the absorbent body 23 from the non-skin-facing side Z2. The back sheet 22 is adhered to the surface of the non-skin-facing side Z2 of the absorbent body 23, for example, with a hot melt adhesive (not shown).

[0051] The absorbent body 23 is disposed between the topsheet 21 and the backsheet 22 of the inner body 20. As shown in FIG. 5 , the absorbent body 23 includes an absorbent core 31 that absorbs the wearer's urine and other excrement that has passed through the topsheet 21, and a pair of white tissues 32 that cover the skin-facing side Z1 of the absorbent core 31. The width (length in the width direction X) of the absorbent body 23 (absorbent core 31) is approximately the same as the width of the inner body 20. The length (length in the longitudinal direction Y) of the absorbent body 23 (absorbent core 31) is slightly shorter than the length of the inner body 20. Specifically, the ventral end 31a of the absorbent core 31 is located closer to the back than the ventral end 20a of the inner body 20 (topsheet 21, etc.). Furthermore, the dorsal end 31b of the absorbent core 31 is located closer to the back than the dorsal end 20b of the inner body 20 (topsheet 21, etc.).

[0052] The absorbent core 31 is layered on the backsheet 22. The absorbent core 31 contains, for example, pulp fibers and a superabsorbent polymer (SAP) and absorbs the wearer's urine. The pulp used in the absorbent core 31 may be, for example, chemical pulp, cellulose fiber, rayon, acetate, or other cellulose fibers. The superabsorbent polymer may be, for example, a starch-based, acrylic acid-based, or amino acid-based particulate or fibrous polymer.

[0053] The pair of white tissues 32 are arranged to cover the skin-facing side Z1 of the absorbent core 31. As an example, the pair of white tissues 32 each extend from the outer edge of the absorbent core 31 in the width direction X to the center in the width direction X, and are arranged to overlap each other in the center in the width direction X. When viewed from the thickness direction Z, each of the pair of white tissues 32 is formed in a rectangular shape extending from the ventral end 31a to the dorsal end 31b of the absorbent core 31. In other words, the edge of each white tissue 32 in the longitudinal direction Y overlaps the edge of the absorbent core 31 in the longitudinal direction Y (the ventral end 31a and the dorsal end 31b).

[0054] The pair of side sheets 24 are located at the ends of the inner body 20 in the width direction X. The pair of side sheets 24 form a pair of leakage-preventing gathers 25 for preventing leakage of excrement, such as urine, excreted by the wearer in the width direction X (side leakage). The pair of leakage-preventing gathers 25 are provided on both sides of the absorbent body 23 in the width direction X, fixed at both ends in the longitudinal direction Y (fixed areas FA), and configured to be able to stand up by contracting the portion between the fixed areas FA in the longitudinal direction Y. As an example, the leakage-preventing gathers 25 have a structure in which multiple (e.g., four) elastic members 26 extending in the longitudinal direction Y are arranged inside the side sheets 24 folded into a bag shape. Note that FIG. 3 illustrates only one elastic member 26 out of the four elastic members 26 included in each leakage-preventing gather 25 shown in FIG. 5 . By contracting this elastic member 26 in the longitudinal direction Y, the portion of the side sheets 24 located between the fixed areas FA functions as the leakage-preventing gathers 25. The elastic member 26 is made of an elastic material such as rubber thread or flat rubber.

[0055] As shown in FIGS. 3 and 5 , a pair of recesses 311 are provided in a portion of the absorbent core 31 included in the crotch region 1c. The pair of recesses 311 extend in the longitudinal direction Y on both sides of the centerline CL1, and are portions of the absorbent core 31 where the thickness in the thickness direction Z is smaller than that of the surrounding area. As an example, the recesses 311 may be formed by layering materials (e.g., SAP, pulp) constituting the absorbent core 31 only in an area on the backsheet 22 excluding a partial area (an area where the recesses 311 are to be formed). In this case, the recesses 311 are portions where the materials constituting the absorbent core 31 are not present and the absorbent core 31 has no thickness (i.e., a thickness of 0). Alternatively, the recesses 311 may be regions where the materials constituting the absorbent core 31 are arranged, but where the amount of materials is less than that of other portions of the absorbent core 31 (portions other than the recesses), resulting in a thinner region than the other portions. According to the above configuration, it is possible to deform the absorbent core 31 starting from a pair of recesses 311, so that the wide absorbent core 31 improves the effect of preventing side leakage while reducing the discomfort that the wearer may experience when wearing the absorbent core 31 due to the wide absorbent core 31.

[0056] 3 , in this embodiment, each of the pair of recesses 311 has a ventral curved portion 311a that curves outward in the width direction X from the center position of the recess 311 in the longitudinal direction Y toward the ventral side, and a dorsal curved portion 311b that curves outward in the width direction X from the center position of the recess 311 toward the dorsal side. That is, each recess 311 has a bow shape in which the center position in the longitudinal direction Y is located at the innermost position in the width direction X and both end positions in the longitudinal direction Y are located at the outermost positions in the width direction X. According to the above configuration, the pair of recesses 311 each having the ventral curved portion 311a and the dorsal curved portion 311b can improve fit around the wearer's legs, and as a result, can effectively reduce any discomfort the wearer may experience when wearing the garment.

[0057] As shown in FIGS. 3 and 5 , a portion of the absorbent core 31 included in the crotch region 1c is provided with a groove 312 extending in the longitudinal direction Y along the centerline CL1 and having a smaller thickness in the thickness direction Z than the surrounding area. As an example, the groove 312, like the pair of recesses 311, can be formed by layering a material (e.g., SAP, pulp) constituting the absorbent core 31 only in an area on the backsheet 22 excluding a partial area (an area where the groove 312 is to be formed). In this case, the groove 312 is formed by a portion of the absorbent core 31 where no material constituting the absorbent core 31 is present and where the absorbent core 31 has no thickness (i.e., a thickness of 0). In this embodiment, both the pair of recesses 311 and the groove 312 are formed by layering a material constituting the absorbent core 31 only in an area excluding the area where the pair of recesses 311 and the groove 312 are to be formed. The groove 312 is positioned between the pair of recesses 311, facing the wearer's urethral opening. As an example, the groove portion 312 is formed in a rectangular shape that is long in the longitudinal direction Y when viewed from the thickness direction Z.

[0058] According to the above configuration, urine excreted by the wearer (urine that has permeated the topsheet 21) can be suitably diffused along the grooves 312 in the longitudinal direction Y of the absorbent core 31, thereby improving the urine absorption efficiency of the absorbent core 31. Furthermore, since the absorbent core 31 is deformable along the grooves 312, the absorbent core 31 can be improved in its adhesion to the wearer's urethral opening. Furthermore, by forming the absorbent core 31 into a wide shape and providing the grooves 312, as in this embodiment, the area of ​​the absorbent core 31 that exists outside the adhesion portion (the portion facing the urethral opening) in the width direction X can be sufficiently increased, while improving the adhesion of the absorbent core 31 to the wearer's urethral opening. This effectively reduces the risk of urinary leakage, providing the user with an even greater sense of security when wearing the pants-type absorbent article 1.

[0059] As shown in Figures 3 and 5, the inner body 20 has an elastic member 27 that stretches at least a portion of the absorbent core 31 in the crotch region 1c along the centerline CL1 in the longitudinal direction Y. The elastic member 27 is made of an elastic material such as rubber thread or flat rubber, similar to the elastic member 26. In this embodiment, as an example, the topsheet 21 described above is formed in a bag shape to cover the sides of the absorbent core 31 and the non-skin-facing side Z2 of the backsheet 22. The elastic member 27 is fixed and disposed between the backsheet 22 and the topsheet 21 on the non-skin-facing side Z2 of the backsheet 22. This prevents sagging (i.e., movement away from the urethral opening) of the contact portion of the absorbent core 31 (the portion that deforms along the groove portion 312 to contact the urethral opening), effectively improving the contact of the absorbent core 31 with the wearer's urethral opening.

[0060] Furthermore, in the present embodiment, as an example, the elastic members 27 are arranged at positions corresponding to the grooves 312 when viewed from the thickness direction Z (in the present embodiment, positions along the edges of the grooves 312). More specifically, a pair of elastic members 27, each extending in the longitudinal direction Y, are arranged along both side edges of the grooves 312 in the width direction X. This makes it possible to more effectively prevent sagging (i.e., movement away from the urethral opening) of the close-fitting portions of the absorbent core 31 (portions that deform along the grooves 312 so as to fit closely to the urethral opening), and to more effectively improve the close-fitting of the absorbent core 31 to the wearer's urethral opening.

[0061] Fig. 6 is a side view showing an example of a packaging body 90 that stores a plurality of pant-type absorbent articles 1. The packaging body 90 includes a packaging sheet 91 for packaging a plurality of pant-type absorbent articles 1. The packaging sheet 91 is formed, for example, in the shape of a bag that has a substantially rectangular parallelepiped shape when the plurality of pant-type absorbent articles 1 is stored therein. The packaging sheet 91 is made of, for example, a synthetic resin such as polyethylene, polypropylene, or polyethylene terephthalate. As shown in Fig. 6, the packaging body 90 may store a plurality of pant-type absorbent articles 1 stacked in multiple layers (two layers in the example of Fig. 6).

[0062] The state of each pant-type absorbent article 1 contained in the package 90 will be described with reference to FIGS. 7 and 8 . FIG. 7 is a view of the pant-type absorbent article 1 in an unfolded state as viewed from the front ventral side. FIG. 7 is a view of the pant-type absorbent article 1 (see FIG. 1 ) in a usable (wearable) state with the pair of side seal portions 10 a uncut as viewed from the front ventral side. FIG. 8 shows the pant-type absorbent article 1 in a folded state. In this folded state, the main body portion 50 is folded in half along a fold point FL2 extending parallel to the width direction X. In this embodiment, as an example, the folded state is a state in which the main body portion 50 is folded in half along the fold point FL2 after wing folding, which will be described later. The fold point FL2 is set so that the length of the pant-type absorbent article 1 in the longitudinal direction Y is approximately half. For example, the fold point FL2 is defined as a fold line along which the pant-type absorbent article 1 is folded in half when being contained in the package 90. The fold starting point FL2 may be set at a position where the length of the pants-type absorbent article 1 in the longitudinal direction Y is half (i.e., a position where the end of the waist opening H1 overlaps with the end 10d described later), or it may be set so that when folded in half as in this embodiment, the end of the waist opening H1 is positioned slightly inside the end 10d.

[0063] In the present embodiment, as an example, the folded pants-type absorbent article 1 is obtained by the following procedure. First, as shown in FIG. 7 , the pants-type absorbent article 1 is arranged so that the ventral portion (the portion corresponding to the ventral region 1a located on the front side in FIG. 7 ) and the dorsal portion (the portion corresponding to the dorsal region 1b located on the rear side in FIG. 7 ) overlap and are flattened. Then, the portions of the ventral and dorsal portions of the main body portion 50 that are outward in the width direction X from the folding point FL1 are folded toward the front side (ventral side) along the folding point FL1. The folding point FL1 is a fold line that runs along the edge of the width direction X of the inner body 20 in the ventral region 1a. For example, the folding point FL1 is along a pair of edges 31c (or near the pair of edges 31c) of the thick absorbent core 31 in the width direction X. Therefore, the thickness (strength) of the main body portion 50 changes with the folding point FL1 as a boundary line, making it possible to easily fold the main body portion 50 along the folding point FL1. Hereinafter, folding the main body portion 50 along the folding starting point FL1 as described above will be referred to as a “wing fold.” When the pants-type absorbent article 1 arranged in this manner is viewed from the front, ventral side, the end of the main body portion 50 in the longitudinal direction Y that is opposite to the waist opening H1 (i.e., the folded-back portion of the crotch region 1c) will be defined as the “end 10d of the crotch region 1c.”

[0064] Next, of the wing-folded main body portion 50, the portions of the ventral and dorsal portions that are closer to the waist opening H1 than the fold starting point FL2 are folded toward the front (ventral side) along the fold starting point FL2. This results in a pant-type absorbent article 1 in a folded state as shown in Fig. 8. The package 90 contains a plurality of pant-type absorbent articles 1 that are folded in this manner. Therefore, when a user removes the pant-type absorbent article 1 from the package 90, the user will recognize the pant-type absorbent article 1 in a folded state. The dimension in the longitudinal direction Y of the pant-type absorbent article 1 in a folded state is the length from the fold starting point FL2 to the end 10d.

[0065] (Effects of the Present Embodiment) In the pants-type absorbent article 1 described above, in the folded state ( FIG. 8 ), the width W1 (first width) in the width direction X of the absorbent core 31 along the end 10d of the crotch region 1c in the longitudinal direction Y is equal to or greater than the width W2 (second width) in the width direction X of the inner body 20 along the folding point FL2. That is, in the pants-type absorbent article 1, the absorbent core 31 is formed wide so that the relationship "W1 ≧ W2" is satisfied in the folded state. In the present embodiment, the stretching force of the back elastic member 15 acts on the portion of the inner body 20 along the folding point FL2, so that "W1 > W2" is satisfied. Furthermore, in the present embodiment, the width W1 is equal to or greater than the width W4 (fourth width) in the width direction X of the main body portion 50 along the folding point FL2. Here, the width W4 of the main body portion 50 is slightly larger than the width W2 of the inner body 20 by the amount including the outer body 10. Therefore, the relationship "W1 ≧ W4 > W2" is satisfied in the folded state. In this embodiment, the relationship "W1 > W4 > W2" is satisfied. Furthermore, when the pant-type absorbent article 1 is folded in half, such as when the pant-type absorbent article 1 is removed from the package (wrapping body 90), the user can easily recognize by sight and touch that the absorbent core 31 in the crotch region 1c (i.e., the portion of the absorbent core 31 along the end 10d) is wide. That is, the user can recognize that the portion of the absorbent core 31 on the end 10d side has a sufficient width compared to the portion of the absorbent core 31 on the folding origin FL2 side. This gives the user a sense of expectation that the wide absorbent core 31 will effectively prevent leakage of body exudates. Furthermore, when it is confirmed that no side leakage of body exudates occurs after use of the pant-type absorbent article 1, a sense of security regarding the pant-type absorbent article 1 can be favorably fostered (in other words, a sense of trust in the pant-type absorbent article 1 based on the realization that the previously expected effects have actually been achieved). The absorbent core 31 is also provided with a pair of recesses 311 extending in the longitudinal direction Y on both sides of the center line CL1.This allows the absorbent core 31 to be deformed starting from the pair of recesses 311, thereby reducing discomfort that the wearer may experience when wearing the absorbent core 31 due to the widened absorbent core 31. Therefore, the pants-type absorbent article 1 can improve the comfort and security of the user when worn.

[0066] In the folded state (FIG. 8), the width W1 is equal to or greater than the length L1 (first length) from the fold starting point FL2 in the longitudinal direction Y to the end of the waist opening H1 (the portion where the ventral end 10b and the dorsal end 10c overlap). In other words, "W1≧L1" holds. This configuration more effectively lets the user recognize that the absorbent core 31 is wide in the folded state, thereby more effectively fostering a sense of security in the user regarding prevention of side leakage.

[0067] In the folded state (FIG. 8), the width W1 is equal to or greater than the length L2 (second length) from the fold starting point FL2 in the longitudinal direction Y to the end 10d of the crotch region 1c. That is, "W1≧L2" holds. As shown in FIG. 8, in this embodiment, the end of the waist opening H1 is located more inward in the longitudinal direction Y than the end 10d. That is, "L1<L2" holds. Therefore, the above-described configuration (W1≧L2>L1) can further enhance the above-described effect (the effect of more effectively letting the user recognize that the absorbent core 31 is wide).

[0068] In the folded state (FIG. 8), the width W1 is equal to or greater than the length L3 (third length; see FIG. 7) in the width direction X of the end (ventral end 20a) in the longitudinal direction Y of the inner body 20. In other words, "W1≧L3" is established. This configuration makes it possible to more effectively make the user aware that the absorbent core 31 is wide in the folded state, thereby more effectively fostering a sense of security in the user regarding prevention of side leakage.

[0069] In the folded state (FIG. 8), the width W1 is equal to or greater than the length L4 (fourth length; see FIG. 7), which is the length of the ventral region 1a and the dorsal region 1b in the longitudinal direction Y (i.e., the length of the side seal portion 10a common to the ventral region 1a and the dorsal region 1b in the longitudinal direction Y). In other words, "W1≧L4" is established. This configuration more effectively allows the user to recognize that the absorbent core is wide in the folded state, thereby more effectively fostering a sense of security in the user regarding prevention of side leakage.

[0070] 2 and 3 , the pair of recesses 311 are arranged so as not to overlap with the elastic members 14, 15, and 16 provided to expand and contract the main body 50 (exterior body 10) in the width direction X. According to the above configuration, the portion of the absorbent core 31 that is particularly susceptible to deformation in the crotch region 1c (i.e., the portion provided with the pair of recesses 311) is prevented from overlapping with the elastic members 14, 15, and 16 that expand and contract in the width direction X, thereby preventing the portion of the absorbent core 31 from shrinking in the width direction X. This allows the portion of the absorbent core 31 included in the crotch region 1c to maintain a wide width in the folded state. As a result, the user is more effectively made aware of the wideness of the absorbent core 31.

[0071] 2 and 8, the absorbent core 31 has a portion 31d in the crotch region 1c that extends outward in the width direction X beyond the exterior body 10. In this embodiment, as shown in FIGS. 2 and 8, the portion 31d extends outward in the width direction X beyond the exterior body 10 in both the unfolded state and the folded state. Furthermore, when the garment is worn correctly so that the portion 31d does not tuck inward, the portion 31d remains extended outward in the width direction X beyond the exterior body 10 even in the worn state. According to the above configuration, by forming the absorbent core 31 in the crotch region 1c wide enough to extend outward in the width direction X beyond the exterior body 10, the user can more effectively recognize that the absorbent core 31 is wide in each state (folded state, unfolded state, and worn state).

[0072] Furthermore, the above-described configuration (the configuration in which the absorbent core 31 has the portion 31d) provides the following effects regardless of whether or not the above-described dimensional relationships in the folded state are satisfied. That is, the user can easily recognize by sight and touch that the absorbent core 31 in the crotch region 1c is wide, due to the portion 31d that protrudes outward from the outer casing 10 in the width direction X. This gives the user a sense of expectation that the wide absorbent core 31 will effectively prevent leakage of body exudates. Furthermore, when it is confirmed that no side leakage of body exudates occurs after use of the pant-type absorbent article 1, a sense of security regarding the pant-type absorbent article 1 can be favorably fostered (in other words, a sense of trust in the pant-type absorbent article 1 based on the realization that the above-described expected effects have actually been achieved). Therefore, the pant-type absorbent article 1 having the above-described configuration (the configuration in which the absorbent core 31 has the portion 31d) can improve the user's sense of security.

[0073] Furthermore, the portion 31d of the absorbent core 31 is located in a position facing the musculus gracilis of the wearer when the article is worn. According to the above configuration, the absorbent core 31 is formed wide so as to cover the portion where a gap is likely to occur between the wearer and the pants-type absorbent article 1 when the thighs become thinner due to a decrease in muscle thickness caused by aging (i.e., the portion corresponding to the musculus gracilis of the wearer), thereby more effectively improving the sense of security of the user.

[0074] The non-skin-facing side Z2 of the portion 23a (see FIGS. 2 and 8 ), which extends further outward in the width direction X than the exterior body 10 in the crotch region 1c of the absorbent body 23 and in which the absorbent core 31 (portion 31d) is disposed, may be colored a color different from that of the exterior body 10. For example, when the exterior body 10 is uncolored (white), the non-skin-facing side Z2 of the portion 23a may be colored a color (e.g., blue) that distinguishes it from the exterior body 10. This configuration makes it easier to visually recognize the portion 31d (i.e., the colored portion) including the edge 31c in the width direction X of the absorbent core 31, which is formed wide in the crotch region 1c, from the non-skin-facing side Z2. As a result, the user can more effectively recognize that the absorbent core 31 is wide in the folded state.

[0075] At least one of the entire non-skin-facing side Z2 of the absorbent body 23 where the absorbent core 31 is located and the exterior body 10 may be colored so that the entire non-skin-facing side Z2 of the absorbent body 23 where the absorbent core 31 is located and the exterior body 10 are different colors. For example, when the exterior body 10 is uncolored (white), the entire non-skin-facing side Z2 of the absorbent body 23 where the absorbent core 31 is located may be colored in a color (e.g., blue) that is distinguishable from the exterior body 10. As an example, as shown in FIG. 9 , the absorbent body 23 may have colored tissue 33 arranged on the non-skin-facing side Z2 of the absorbent core 31 (e.g., between the absorbent core 31 and the backsheet 22). The colored tissue 33 is a material colored in a color that is distinguishable from the exterior body 10. Alternatively, the absorbent body 23 may be uncolored (white), and the exterior body 10 may be colored in a color (e.g., blue) that is distinguishable from the absorbent body 23. According to the above configuration, by emphasizing the contrast (color difference) between the absorbent body 23 (absorbent core 31) and the exterior body 10, it is possible to make it easier to visually grasp the position of the absorbent core 31 in a folded state ( FIG. 8 ), etc.

[0076] Furthermore, in the packaging body 90, the plurality of pant-type absorbent articles 1 are housed in a folded state ( FIG. 8 ), and each pant-type absorbent article 1 satisfies the above-described relationship "W1≧W4" in the folded state. As described above, in this embodiment, the relationship "W1>W4" is satisfied. Also, as shown in FIG. 8 , the width W1 is equal to or greater than the width W3 (third width) in the width direction X of the end of the waist opening H1 (the portion where the ventral end 10b and the dorsal end 10c overlap). That is, in the folded state, the relationship "W1≧W3" is also satisfied. In this embodiment, the width of the portion including the end of the waist opening H1 is reduced by the above-described wing folding, and the stretchable force of the back elastic member 15 acts on this portion, so that "W1>W3" is satisfied. As a result, when the user removes the pant-type absorbent article 1 from the packaging 90, the user can easily recognize by sight and touch that the absorbent core 31 in the crotch region 1c is wide when the pant-type absorbent article 1 is folded in half. This gives the user a sense of expectation that the wide absorbent core 31 will effectively prevent leakage of body waste. Furthermore, when it is confirmed that no side leakage of body waste occurs after use of the pant-type absorbent article 1, a sense of security regarding the pant-type absorbent article 1 can be suitably fostered (in other words, a sense of trust in the pant-type absorbent article 1 based on the realization that the effects that were expected as described above have actually been achieved). Therefore, the packaging 90 can improve the user's sense of security.

[0077] In the folded state (FIG. 8), it is preferable that width W3 is less than width W1 (W1>W3). In this case, the portion of the absorbent core 31 located in the crotch region 1c (i.e., the portion having width W1) protrudes outward in the width direction X from the portion including the end of the waist opening H1 of the main body portion 50 (i.e., the portion having width W3). Therefore, in the folded state shown in FIG. 8, the wide portion of the absorbent core 31 (i.e., the portion protruding outward in the width direction X as described above) can be recognized by the user. As a result, the above-mentioned effect (improved sense of security for the user) can be further enhanced. From the viewpoint of further enhancing the above-mentioned effect, it is more preferable that width W1 be 1.5 times or more than width W3. According to the above configuration, the visibility of the wide portion of the absorbent core 31 in the crotch region 1c is more effectively improved in the folded state, thereby more suitably improving the sense of security for the user.

[0078] [Modifications] Although the embodiments of the present disclosure have been described above, the present disclosure is not limited to the above embodiments. The materials and shapes of each component are not limited to those described above, and various materials and shapes can be used. Furthermore, some components of the pants-type absorbent article 1 and the packaging body 90 described above may be modified to other configurations or omitted.

[0079] For example, in the above embodiment, the recesses 311 are formed in a shape that extends continuously in the longitudinal direction Y, but the recesses 311 may be formed discontinuously. In this case, a set of a plurality of recesses that are formed discontinuously may be defined as the recesses 311. Furthermore, the recesses 311 may be compressed grooves formed by, for example, embossing.

[0080] Furthermore, in the above embodiment, the folded state was defined as a state in which the pant-type absorbent article 1 is folded in half along the fold point FL2 so that the ventral portion faces inward, but the folded state may also be defined as a state in which the pant-type absorbent article 1 is folded in half in the opposite direction (i.e., a state in which the pant-type absorbent article 1 is folded in half along the fold point FL2 so that the dorsal portion faces inward). Furthermore, in the above embodiment, the folded state was defined as a state in which the pant-type absorbent article 1 is wing-folded along the fold point FL1 and then folded along the fold point FL2, but the wing fold may be omitted. Furthermore, the folded state of the pant-type absorbent article 1 described above does not necessarily have to match the state when it is contained in the packaging body 90. For example, when the pant-type absorbent article 1 is not contained in the packaging body 90 in a folded state, the folded state of the pant-type absorbent article 1 described above may be defined as a state in which the length of the pant-type absorbent article 1 in the longitudinal direction Y is half the length of the pant-type absorbent article 1 in an unfolded state (i.e., the length from the end of the waist opening H1 to the end 10d).
