Description

[Technical Field]

[0001] The present disclosure relates to a set of absorbent articles. [Background technology]

[0002] Conventionally, there is known an absorbent article that is capable of preventing leakage of body waste by providing a pair of side absorbent bodies on both sides of a central absorbent body and making the pair of side absorbent bodies easier to stand up (see Patent Document 1). [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Japanese Patent Application Laid-Open No. 2013-102888 Summary of the Invention [Problem to be solved by the invention]

[0004] The color of an absorbent body, including an absorbent core, is generally white and often the same color as the other components of an absorbent article. Therefore, even if the leak prevention effect is improved by increasing the width of the absorbent core, as in the absorbent article described in Patent Document 1, the user of the absorbent article cannot easily visually recognize that the absorbent core is wider. As a result, it is difficult for the user to feel a sense of security about the absorbent article (in other words, a sense of expectation that the absorbent core will effectively prevent leakage of body exudates, or a sense of the effect that the absorbent article effectively suppresses leakage of body exudates around the legs). Cultivating such a sense of security about the absorbent article is extremely important for alleviating the user's anxiety and allowing the user to live a comfortable life, especially when the absorbent article is used for long periods of time or at night.

[0005] Therefore, one aspect of the present disclosure aims to provide an absorbent article set that can effectively improve the sense of security of the user. [Means for solving the problem]

[0006] An absorbent article set according to one aspect of the present disclosure is an absorbent article set including an absorbent article that is a pants-type or tape-type disposable diaper having a ventral region that is located on the ventral side of a wearer when worn, a dorsal region that is located on the dorsal side of the wearer when worn, and a crotch region that is located between the ventral region and the dorsal region, arranged along the longitudinal direction, and an absorbent pad that is attached to the absorbent article when used, wherein the absorbent article has a liquid-permeable top sheet that is located on the skin-facing side of the wearer when worn, a liquid-impermeable back sheet that is located on the non-skin-facing side of the wearer when worn, and an absorbent body that is disposed between the top sheet and the back sheet and includes an absorbent core that absorbs excrement of the wearer, and the absorbent body has a pair of colored regions that are arranged to overlap with the absorbent core in the thickness direction that is perpendicular to the longitudinal and width directions on both sides of a center line that passes through the center of the absorbent body in the width direction that is perpendicular to the longitudinal direction and is parallel to the longitudinal direction, and a pair of colored regions that are provided on the absorbent core. and a non-colored region disposed between the pair of colored regions in the width direction on the same side as the absorbent core, the outer edge of each of the pair of colored regions in the width direction being disposed so as to overlap an edge of the absorbent core in the width direction, the number of sheet materials laminated on the pair of colored regions on the side opposite to the side on which the absorbent core is disposed relative to the pair of colored regions being equal to or less than the number of sheet materials laminated on the non-colored region on the side opposite to the side on which the absorbent core is disposed relative to the non-colored region, the pair of colored regions and the non-colored region being disposed closer to the wearer's skin than the absorbent core, and when the absorbent pad is attached to the skin-facing side of the absorbent article so that the center line passes through the center of the absorbent pad in the width direction, the outer edge of the pair of colored regions in the width direction is located outside the outer end of the absorbent pad in the width direction at a central position of the absorbent body in the longitudinal direction.

[0007] In the absorbent article set of the above embodiment, even when the absorbent pad is attached to the absorbent article for use in combination with the absorbent article, the outer edges of the pair of colored regions can be visually recognized by the user at the center of the absorbent body in the longitudinal direction. This allows the user to visually understand that the absorbent article has an absorbent core that is wider than the absorbent pad in the region where side leakage is a concern (i.e., the center of the absorbent body in the longitudinal direction). As a result, the user's sense of security can be effectively improved. [Effects of the Invention]

[0008] According to the present disclosure, it is possible to provide an absorbent article set that can effectively improve the sense of security of the user. [Brief explanation of the drawings]

[0030] [Embodiment] 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.

[0031] An absorbent article 1 according to one embodiment will now be described. Fig. 1 is a perspective view of the absorbent article 1. Fig. 2 is a plan view of the absorbent article 1 as viewed from the non-skin-facing side Z2, and Fig. 3 is a plan view of the 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. Fig. 5 (A) and (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.

[0032] In the following description, a "wearer" is a person who wears the absorbent article 1. The "skin-facing side" is the side that faces the wearer's skin when the absorbent article 1 is worn by the wearer (hereinafter referred to as "worn state"). The "non-skin-facing side" is the side that faces away from the wearer's skin when worn. The "user" of the absorbent article 1 includes the wearer described above, as well as a helper (caregiver) who raises or looks after the wearer, who is a child or a person being cared for.

[0033] As shown in Fig. 1, the absorbent article 1 is, for example, a pants-type disposable diaper that absorbs urine and other body waste from a wearer. That is, the 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 absorbent article 1 is composed of an exterior body 10 that faces outward (non-skin-facing side Z2) when worn, and an interior body 20 fixed to the interior of the exterior body 10. The absorbent article 1 is configured to be cut by tearing a pair of side seal portions 10a of the exterior body 10 provided on both the left and right sides of the wearer.

[0034] 2 and 3 show the absorbent article 1 in an unfolded state in which the exterior body 10 is cut along a pair of side seal portions 10a and the absorbent article 1 is stretched to a state in which no wrinkles are formed. In the following explanation, unless otherwise specified, the shape and positional relationship of each part of the absorbent article 1 in the unfolded state will be described.

[0035] As shown in Figures 2 and 3, the absorbent article 1 has a configuration in which a ventral region 1a located on the ventral side of the wearer when worn, a dorsal region 1b located on the dorsal side of the wearer when worn, and a crotch region 1c located between the ventral region 1a and the dorsal region 1b are arranged along the longitudinal direction Y.

[0036] In the unfolded state, the absorbent article 1 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 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."

[0037] When the absorbent article 1 is a pants-type diaper as in this embodiment, the ventral region 1a is defined as the portion of the absorbent article 1 in the unfolded state (see FIGS. 2 and 3) that extends from the ventral end 10b of the exterior body 10 to the dorsal end of the ventral side seal 10a. Similarly, the dorsal region 1b is defined as the portion of the absorbent article 1 in the unfolded state that extends from the dorsal end 10c of the exterior body 10 to the ventral end of the dorsal side seal 10a. Note that when the absorbent article 1 has a configuration other than a pants-type diaper (for example, a tape-type diaper or an absorbent pad), the ventral region 1a and the dorsal region 1b may be defined by other methods. For example, when the entire absorbent article 1 is divided into four equal parts in the longitudinal direction Y, the two central regions may be defined as the crotch region 1c, and the regions on either side of the crotch region 1c may be defined as the ventral region 1a and the dorsal region 1b.

[0038] (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 back-side sheet 13. For 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 (hourglass-shaped in this embodiment). 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 back 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 back-side sheet 13 is disposed so as to overlap the main body sheet 11 in the back region 1b. The main body sheet 11 is formed of, for example, an SMS nonwoven fabric. The ventral-side sheet 12 and the back-side sheet 13 are formed of, for example, a spunbond nonwoven fabric.

[0039] 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 on the non-skin-facing side Z2 (outside) of the main body sheet 11.

[0040] The end 121a of the folded inner portion 121 is located on the dorsal side of the ventral end 20a of the inner body 20 and on the ventral side of the ventral end 31a of the absorbent core 31 contained in the inner body 20.

[0041] 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 stretch members 14 are arranged in 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 stretch 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 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 stretch members 14 are made of an elastic material such as rubber thread or spandex.

[0042] The back-side sheet 13 is folded back so as to sandwich the back-side end portion 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 on the non-skin-facing side Z2 (outside) of the main body sheet 11.

[0043] The end 131a of the folded inner portion 131 is located on the ventral side of the dorsal end 20b of the inner body 20 and on the dorsal side of the dorsal end 31b of the absorbent core 31 contained in the inner body 20.

[0044] 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 absorbent article 1. Therefore, like the ventral waist portion provided with the above-mentioned abdominal stretchable members 14, the back waist portion of the exterior 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.

[0045] Between the outer portion 132 and the main body sheet 11, a plurality of (three in this embodiment) leg-hole stretchable members 16 are arranged in the longitudinal direction Y, closer to the ventral side than the plurality of back-hole stretchable members 15. As shown in FIG. 2, each leg-hole stretchable member 16 extends in the width direction X between the edges 1e of the back region 1b of the 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 stretchable members 16 allows the outer body 10 to stretch to fit the wearer's legs. The plurality of leg-hole stretchable members 16 are made of an elastic material, such as rubber thread or spandex.

[0046] 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 back 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) 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 absorbent article 1 has a configuration in which the outer body 10 and the inner body 20 are integrally joined.

[0047] (Interior body configuration) 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.

[0048] The topsheet 21 is located on the skin-facing side Z1 of the wearer when worn, and constitutes 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 absorbent body 23 from the skin-facing side Z1. Typically, the topsheet 21 is plain white. The topsheet 21 is adhered to the surface of the skin-facing side Z1 of the absorbent body 23 (the surfaces of the white tissue 32 and colored tissue 33 described below) with, for example, a hot melt adhesive (not shown).

[0049] 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 sandwiched between them. 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 by, for example, a hot melt adhesive (not shown).

[0050] 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 urine and other body waste that passes through the topsheet 21; a pair of white tissues 32 that cover the skin-facing side Z1 of the absorbent core 31; and a pair of colored tissues 33 that are disposed on the pair of white tissues 32. 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.). The back end 31b of the absorbent core 31 is located closer to the back than the back end 20b of the inner body 20 (topsheet 21, etc.).

[0051] 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.

[0052] 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 extend from the outer edges 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).

[0053] The pair of colored tissues 33 are tissues colored in a color other than white (blue, for example). The pair of colored tissues 33 are arranged so as to overlap the absorbent core 31 in the thickness direction Z on both sides of a center line CL1 that passes through the center of the absorbent body 23 (absorbent core 31) in the width direction X and is parallel to the longitudinal direction Y. The outer end portions 33a of each of the pair of colored tissues 33 in the width direction X are arranged so as to overlap the edge 31c of the absorbent core 31 in the width direction X. When viewed from the thickness direction Z, each of the pair of colored tissues 33 is formed in a rectangular shape extending from the ventral end portion 31a to the dorsal end portion 31b of the absorbent core 31. That is, the edge 33b (see FIG. 3) of each colored tissue 33 in the longitudinal direction Y overlaps the edge (ventral end portion 31a and dorsal end portion 31b) of the absorbent core 31 in the longitudinal direction Y.

[0054] Here, since the topsheet 21 is a liquid-permeable nonwoven fabric as described above, the color of the components on the non-skin-facing side Z2 of the topsheet 21 can be seen through from the skin-facing side Z1 of the topsheet 21. Therefore, the colors of the pair of colored tissues 33 can be visually recognized from the skin-facing side Z1. That is, as shown in FIG. 3 , a pair of colored tissues 33 form a pair of colored regions A1. Furthermore, on the same side of the absorbent core 31 as the side on which the pair of colored regions A1 is provided (the skin-facing side Z1 in this embodiment), a non-colored region A2 is formed between the pair of colored regions A1 in the width direction X. The colored region A1 is the region where the colored tissues 33 are arranged, and when viewed from the skin-facing side Z1 of the topsheet 21, the color of the colored tissues 33 (blue in this embodiment) can be seen through. The non-colored region A2 is a region where the colored tissues 33 are not arranged, and is a region where the white (uncolored) color of the white tissues 32 is visible when viewed from the skin-facing side Z1 of the topsheet 21. That is, in this embodiment, the colored tissues 33 function as a member that constitutes the colored region A1, and the white tissues 32 mainly function as a member that constitutes the non-colored region A2 (white region).

[0055] 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. When this elastic member 26 contracts in the longitudinal direction Y, the portion of the side sheets 24 arranged 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.

[0056] (Actions and Effects of Absorbent Article 1) 3, in the absorbent article 1 described above, each outer edge portion (outer end portion 33a of the colored tissue 33) of the pair of colored regions A1 in the width direction X is arranged to overlap with the edge 31c of the absorbent core 31 in the width direction X. Furthermore, the quantity X1 of sheet materials stacked on the pair of colored regions A1 (colored tissue 33) on the side opposite (skin-facing side Z1) to the side where the absorbent core 31 is arranged (non-skin-facing side Z2) relative to the pair of colored regions A1 (colored tissue 33) is equal to or less than the quantity X2 of sheet materials stacked on the non-colored region A2 (white tissue 32) on the side opposite (skin-facing side Z1) to the side where the absorbent core 31 is arranged (non-skin-facing side Z2) relative to the non-colored region A2 (white tissue 32) (i.e., "X1≦X2"). In this embodiment, as shown in Fig. 5, the only sheet material placed on the colored area A1 (colored tissue 33) is the topsheet 21, so "X1 = 1 topsheet 21". Similarly, the only sheet material placed on the non-colored area A2 (white tissue 32) is the topsheet 21, so "X2 = 1 topsheet 21". Therefore, "X1 = X2" is established.

[0057] As described above, the absorbent article 1 is provided with a pair of colored regions A1 having outer edges that overlap the edges 31c of the absorbent core 31 in the width direction X, and the number X1 of sheet materials stacked on the pair of colored regions A1 is equal to or less than the number X2 of sheet materials stacked on the non-colored regions A2 (in this embodiment, X1 = X2). That is, by not disposing a greater number of sheet materials on the pair of colored regions A1 than the non-colored regions A2, the visibility of the pair of colored regions A1 is not unnecessarily impaired. This allows the user to properly view the pair of colored regions A1 and easily grasp the position of the edges 31c of the absorbent core 31 in the width direction X. As a result, the user can expect that the absorbent core 31, which is positioned up to a position that overlaps the outer edges of the pair of colored regions A1 (the outer ends 33a of the colored tissues 33), will effectively prevent leakage of body waste. Furthermore, when it is confirmed that no side leakage of body waste has occurred after use of the absorbent article 1, it is possible to suitably foster a sense of security in the absorbent article 1 (in other words, a sense of trust in the absorbent article 1 based on the realization that the effects that were expected in advance as described above have actually been achieved). Therefore, the absorbent article 1 can effectively improve the sense of security of the user.

[0058] Furthermore, the area along the edge of the colored area A1 in the width direction X (the outer edge 33a of the colored tissue 33) is configured so that the number of stacked sheet materials is not greater than in other areas within the colored area A1. In other words, the entire colored area A1 has similar visibility, and the area along the edge of the colored area A1 (the outer edge 33a) that is particularly desired to be visible to the user is configured so that visibility is not impaired compared to other areas within the colored area A1. This allows the user to easily visually determine the position of the edge 31c of the absorbent core 31 through the colored area A1.

[0059] The pair of colored regions A1 and non-colored region A2 are arranged closer to the wearer's skin side Z1 than the absorbent core 31. According to the above configuration, when the absorbent article 1 is put on a wearer (i.e., when the user visually recognizes the skin side Z1 of the absorbent article 1), the pair of colored regions A1 allow the user to visually recognize the region where the absorbent core 31 is arranged (the position of the edge 31c in the width direction X), thereby preferably giving the user a sense of security about the absorbent article 1.

[0060] 5(B), when the leakage preventing gathers 25 are folded inward in the width direction X, the inner edge of the colored region A1 in the width direction X (i.e., the inner end 33c of the colored tissue 33) is located more inward in the width direction X than the apex 25a of the leakage preventing gathers 25. According to the above configuration, even when the leakage preventing gathers 25 are folded inward in the width direction X to the maximum extent, the colored region A1 is not completely hidden by the leakage preventing gathers 25, and therefore the visibility of the colored region A1 can be ensured.

[0061] 5(B), when the leakage preventing gathers 25 are folded inward in the width direction X, the edge 31c of the absorbent core 31 in the width direction X is located further outward in the width direction X than the apex 25a of the leakage preventing gathers 25 at the center position of the absorber 23 in the longitudinal direction Y (on the center line CL2 in FIG. 3). According to the above configuration, by forming the absorbent core 31 into a wide shape that has the above-mentioned positional relationship with the leakage preventing gathers 25 (for example, a shape that does not have a typical waisted shape, or even if there is a waisted portion, the width of the waisted portion is larger than a typical size), the absorbent core 31 can be made more effective in preventing side leakage of body exudates. Furthermore, the colored region A1 visually emphasizes that the absorbent core 31 is wide enough that the position of the edge 31c has the above-mentioned positional relationship with the leakage preventing gathers 25, and therefore the user can be made to feel more comfortable wearing the absorbent article 1. Furthermore, by providing the absorbent core 31 with a wide shape and providing the colored region A1 along the edge 31c of the absorbent core 31 in this manner, even when an absorbent pad such as a urine absorption pad is placed on the inner body 20 (topsheet 21) of the absorbent article 1, the colored region A1 can be made to extend out on both sides of the absorbent pad in the width direction X, allowing the user to visually recognize that the absorbent core 31 is wide. As a result, even when the absorbent article 1 is used in combination with an absorbent pad, the user can be given a favorable sense of security when using the absorbent article 1.

[0062] Furthermore, the absorbent core 31 is formed to have a substantially uniform width throughout the longitudinal direction Y. In this embodiment, the absorbent core 31 is formed to have a rectangular shape of uniform width when viewed from the thickness direction Z. According to the above configuration, the absorbent core 31 does not have a constricted shape and is formed to have a wide width throughout the longitudinal direction Y, thereby improving the effect of preventing side leakage and the sense of security given to the user.

[0063] As shown in FIGS. 3 and 5 , a portion of the absorbent core 31 included in the crotch region 1c is provided with a pair of recesses 311 on both sides of the centerline CL1, each extending in the longitudinal direction Y and having a thickness in the thickness direction Z that is smaller than that of the surrounding area. As an example, the recesses 311 can be formed by layering a material (e.g., SAP, pulp) that constitutes 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 a portion where the material that constitutes the absorbent core 31 is not present and where the absorbent core 31 has no thickness (i.e., a thickness of 0). This configuration allows the absorbent core 31 to be deformed starting from the pair of recesses 311. This improves the side leakage prevention effect of the wide absorbent core 31 while reducing discomfort that may be experienced by the wearer due to the wide absorbent core 31.

[0064] 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 an arched 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 recess 311.

[0065] As shown in FIG. 3 , in this embodiment, the entirety of each of the pair of recesses 311 overlaps with the colored region A1 in the thickness direction Z. As an example, the center position of the recess 311 in the longitudinal direction Y (the portion located most inward in the width direction X) is disposed so as to contact the inner end of the colored region A1 (the inner end 33c of the colored tissue 33) when viewed from the thickness direction Z. According to the above configuration, by overlapping the recess 311, which is the deformation starting point of the absorbent article 1, with the colored region A1, the colored region A1 can be deformed appropriately. This makes it easier for the user to visually observe how the colored region A1 (i.e., the absorbent core 31) appropriately deforms in response to the movement of the legs. As a result, the absorbent article 1 can provide the user with a sense of security.

[0066] As shown in FIG. 6A, each of the pair of recesses 311 may be arranged so that half or more of its area overlaps with the colored region A1 in the thickness direction Z. In this example, the innermost portion of the recess 311 in the width direction X is located inside the inner end 33c of the colored region A1 (colored tissue 33) when viewed from the thickness direction Z, so that half or more of the entire area of ​​the recess 311 overlaps with the colored region A1. Alternatively, as shown in FIG. 6B, each of the pair of recesses 311 may be arranged so that at least a portion of the recess 311 overlaps with the colored region A1 in the thickness direction Z. In this example, only the tip ends of the ventral curved portion 311a and the dorsal curved portion 311b of the recess 311 overlap with the colored region A1. Even with the configuration shown in FIG. 6A or 6B, the above-mentioned effect of making it easier for the user to visually recognize how the colored region A1 (i.e., the absorbent core 31) appropriately deforms in response to the movement of the legs can be obtained. However, from the viewpoint of more suitably obtaining the above-mentioned effect, the form of FIG. 6(B) is more preferable than the form of FIG. 6(C), and the form of the above-mentioned embodiment (FIG. 3) is even more preferable than the form of FIG. 6(B).

[0067] At the center position (on the center line CL2) of the absorbent body 23 in the longitudinal direction Y, the sum (w1 × 2) of the widths w1 of the pair of colored regions A1 in the width direction X may be equal to or greater than the width (w2) of the non-colored region A2 in the width direction X. That is, the width w1 of the pair of colored regions A1 may be set so that "w1 × 2 ≧ w2" holds. For example, as shown in FIG. 7A, the sum of the widths w1 of the colored regions A1 may be configured to be greater than the width w2 of the non-colored region A2. According to the above configuration, by making the widths of the pair of colored regions A1 sufficiently larger relative to the non-colored region A2, the visibility of the pair of colored regions A1 can be effectively improved.

[0068] Alternatively, at the center position (on the center line CL2) of the absorbent body 23 in the longitudinal direction Y, the sum of the widths w1 of the pair of colored regions A1 in the width direction X may be less than or equal to the width w2 of the non-colored region A2 in the width direction X. That is, the widths w1 of the pair of colored regions A1 may be set so that "w1 × 2 ≦ w2" holds. For example, as shown in FIG. 7B, the sum of the widths w1 of the colored regions A1 may be configured to be smaller than the width w2 of the non-colored region A2. According to this configuration, by limiting the width of the pair of colored regions A1 relative to the non-colored region A2 to a certain value or less, the amount of coloring material required to form the pair of colored regions A1 can be reduced. Furthermore, by providing the colored regions A1 only in positions relatively close to the edge 31c of the absorbent core 31, the colored regions A1 can more accurately indicate to the user the position of the edge 31c of the absorbent core 31.

[0069] 3, in this embodiment, the width w1 of the pair of colored regions A1 is set so that the sum (w1×2) of the widths w1 of the pair of colored regions A1 is equal to the width w2 of the non-colored region A2. This configuration makes it possible to obtain a good balance between the advantages of the above-mentioned case where "w1×2≧w2" and the case where "w1×2≦w2".

[0070] Each of the pair of colored regions A1 is preferably disposed over at least the entire crotch region 1c in the longitudinal direction Y. In this embodiment, the ventral end 31a and the dorsal end 31b of the absorbent core 31 reach the ventral region 1a and the dorsal region 1b, respectively, and both ends of each colored region A1 in the longitudinal direction Y (both end edges 33b of the colored tissue 33) overlap the ventral end 31a and the dorsal end 31b of the absorbent core 31, thereby satisfying the above-mentioned arrangement conditions. According to the above configuration, the colored regions A1, which serve as markers for the edge positions of the absorbent core 31, are disposed over the entire crotch region 1c, which is the area most susceptible to side leakage of body excrement (i.e., the area where the user is most likely to be concerned about side leakage), thereby providing a sense of security to the user.

[0071] As shown in FIG. 3, each of the pair of colored regions A1 is preferably arranged so as to overlap with the regions on both sides of the central region R1 in the longitudinal direction Y (the ventral region R2 and the dorsal region R3) when the absorbent article 1 is divided into thirds in the longitudinal direction Y. In this embodiment, the ventral region 1a is included in region R2, and the dorsal region 1b is included in region R3, and each colored region A1 extends from the ventral region 1a to the dorsal region 1b, thereby satisfying the above-mentioned arrangement condition. According to the above configuration, by making the length of the colored region A1 in the longitudinal direction Y sufficiently long, the visibility of the colored region A1 can be improved, and a sense of security for the user can be suitably fostered. Note that, from the viewpoint of further enhancing the above-mentioned effect, it is more preferable that each of the pair of colored regions A1 is arranged so as to overlap with the regions on both sides in the longitudinal direction Y (the regions on both sides excluding the two central regions) when the absorbent article 1 is divided into fourths in the longitudinal direction Y.

[0072] The edges of each of the pair of colored regions A1 in the longitudinal direction Y (edges 33b of the colored tissue 33) overlap with the edges of the absorbent core 31 in the longitudinal direction Y (ventral end 31a and dorsal end 31b). According to the above configuration, by making the length of the colored regions A1 in the longitudinal direction Y sufficiently long to be the same length as the absorbent core 31, the visibility of the colored regions A1 can be improved, and a sense of security for the user can be favorably fostered.

[0073] 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 the material constituting the absorbent core 31 is not present and the absorbent core 31 has no thickness (zero thickness). 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 located between the pair of recesses 311 and in a position facing the wearer's urethral opening. As an example, the groove 312 is formed in a rectangular shape that is long in the longitudinal direction Y when viewed from the thickness direction Z.

[0074] 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 adhesion of the absorbent core 31 to the wearer's urethral opening can be improved, and 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. This effectively reduces the risk of urine leakage, and provides the user with an even greater sense of security when wearing the absorbent article 1.

[0075] As shown in FIGS. 3 and 5, the inner body 20 includes 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 the present embodiment, as an example, the topsheet 21 described above is formed in a bag shape so as to cover the side surfaces 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 so as to contact the urethral opening), effectively improving the contact of the absorbent core 31 with the wearer's urethral opening.

[0076] Furthermore, in this 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 this 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 urethral opening of the wearer.

[0077] [Variations] 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 absorbent article 1 described above may be modified to other configurations or omitted.

[0078] In the above-described embodiment, the pair of colored regions A1 and the non-colored region A2 were arranged on the skin side Z1 with respect to the absorbent core 31. In contrast, for example, as shown in FIG. 8, the pair of colored regions A1 and the non-colored region A2 may be arranged on the non-skin side Z2 with respect to the absorbent core 31. In the example of FIG. 8, the colored tissue 33 constituting the colored region A1 is arranged between the absorbent core 31 and the back sheet 22. Therefore, the quantity X1 of the sheet material laminated on the colored region A1 (colored tissue 33) on the non-skin side Z2 is the quantity of only the back sheet 22 and the front sheet 21 (the portion covering the back sheet 22), whereas the quantity X2 of the sheet material laminated on the non-colored region A2 (white tissue 32) on the non-skin side Z2 is the quantity obtained by adding the absorbent core 31 to the back sheet 22 and the front sheet 21 (the portion covering the back sheet 22). Thus, "X1 < X2" holds. Even if it is considered that the white color of the non-colored region A2 is constituted by the absorbent core 31, "X1 = X2" is obtained, and at least "X1 > X2" does not hold. According to the above configuration, when the absorbent article 1 is taken out from a package (for example, a package containing a plurality of absorbent articles 1, etc.) or after the absorbent article 1 is worn by the wearer (that is, in a scene where the non-skin side Z2 of the absorbent article 1 is visually recognized by the user), the region (the position of the edge 31c in the width direction X) where the absorbent core 31 is arranged is visually grasped by the user by the pair of colored regions A1, so that a sense of security for the absorbent article 1 can be preferably given to the user.

[0079] Note that the configuration of the above-described embodiment and FIG. 8 may be combined. That is, the colored tissue 33 may be arranged on the skin side Z1 with respect to the absorbent core 31 as in the above-described embodiment, and the colored tissue 33 may also be arranged on the non-skin side Z2 with respect to the absorbent core 31 as in the example of FIG. 8. In this case, from both the skin side Z1 and the non-skin side Z2, the position of the edge 31c of the absorbent core 31 can be visually grasped by the user by the colored region A1 constituted by the colored tissue 33, and a sense of security for the absorbent article 1 can be more preferably given to the user.

[0080] In the above embodiment, the shape, width (length in the width direction X), and length (length in the longitudinal direction Y) of one colored region A1 are the same as the shape, width, and length of the other colored region A1, but at least one of the shape, width, and length of one colored region A1 may be different from at least one of the shape, width, and length of the other colored region A1.

[0081] In the above embodiment, the colored region A1 is realized by arranging the colored tissue 33 as a separate member from the absorbent core 31 and the white tissue 32, but the colored region A1 may also be formed by printing (for example, color printing on a part of the white tissue 32). When the colored region A1 is formed by printing, the number of members required to form the colored region A1 can be reduced.

[0082] Furthermore, when printing is used, it is easy to form colored regions A11, A12, and A13 having a predetermined pattern as shown in FIG. 9. Colored region A11 shown in FIG. 9(A) is formed by arranging multiple vertically striped colored portions. Colored region A12 shown in FIG. 9(B) is formed by arranging multiple horizontally striped colored portions. Colored region A13 shown in FIG. 9(C) is formed by regularly arranging multiple dot-shaped colored portions. Note that when a colored region is formed by multiple scattered colored portions in this manner, the region including the multiple colored portions (i.e., a single region that can be perceived as a single region in which multiple colored portions are arranged in a predetermined pattern) can be defined as the region (colored regions A11 to A13) corresponding to colored region A1 described in the above embodiment.

[0083] Furthermore, in the above embodiment, the absorbent article 1 is a pants-type diaper, but the absorbent article 1 may also be a tape-type diaper. Furthermore, the absorbent article 1 may also be an absorbent pad that has the same or similar configuration as the inner body 20 of the above embodiment, but does not include a configuration corresponding to the outer body 10 of the above embodiment. When the absorbent article 1 is configured as a tape-type diaper or an absorbent pad, the "unfolded state" of the absorbent article 1 described in the above embodiment can be rephrased as a state in which the absorbent article 1 is stretched to a state in which no wrinkles are formed.

[0084] As shown in FIG. 10 , the above-described absorbent article 1 may be combined with an absorbent pad 50 to form an absorbent article set 100. The absorbent pad 50 has an absorbent core 51, a topsheet 52 covering the skin-facing side Z1 of the absorbent core 51, and a backsheet 53 covering the non-skin-facing side Z2 of the absorbent core 51. The absorbent core 51 may be made of, for example, the same material as the absorbent core 31 (e.g., SAP, pulp, etc.). As an example, the absorbent pad 50 has a rectangular shape when viewed in the thickness direction Z. However, the shape of the absorbent pad 50 is not limited to the above. For example, the absorbent pad 50 may be formed in an hourglass shape, or may be formed in a shape asymmetric with respect to a central axis parallel to the longitudinal direction Y.

[0085] In the absorbent article set 100, when the absorbent pad 50 is attached to the skin-facing side Z1 of the inner body 20 of the absorbent article 1 so that the center line CL1 passes through the center of the absorbent pad 50 in the width direction X, the outer edges of the pair of colored regions A1 in the width direction X (outer ends 33a of the colored tissue 33) are located outside the outer ends 50a of the absorbent pad 50 in the width direction X at the center of the absorbent body 23 in the longitudinal direction Y (i.e., on the center line CL2). As an example, a joining member for joining the absorbent pad 50 to the inner body 20 (topsheet 21) may be provided on the non-skin-facing side Z2 of the backsheet 53 of the absorbent pad 50. In this case, the absorbent pad 50 can be attached to the inner body 20 by placing the absorbent pad 50 relative to the inner body 20 so that the center line CL1 passes through the center of the absorbent pad 50 in the width direction X, as described above, and pressing the backsheet 53 of the absorbent pad 50 against the topsheet 21 of the inner body 20.

[0086] In the absorbent article set 100 of the above embodiment, even when the absorbent pad 50 is attached to the inner body 20 of the absorbent article 1 to be used in combination with the absorbent article 1, the outer edges (outer ends 33a) of the pair of colored regions A1 can be visually recognized by the user at the center position (on the center line CL2) of the absorbent body 23 in the longitudinal direction Y. This allows the user to visually recognize that the absorbent article 1 has an absorbent core 31 that is wider than the absorbent pad 50 in the region where side leakage is a concern (i.e., the center position of the absorbent body 23 in the longitudinal direction Y). As a result, the user's sense of security can be effectively improved.

[0087] The absorbent articles constituting the absorbent article set 100 do not need to have all of the configuration of the absorbent article 1 of the above embodiment. It is sufficient that at least one pair of colored regions A1 (components constituting the colored regions A1) are arranged closer to the skin side Z1 than the absorbent core 31 and have the wide shape described above on the center line CL2. The absorbent article 1 may also be a tape-type disposable diaper. Even in this case, the same effects as those described above when the absorbent article 1 is a pants-type disposable diaper can be obtained. The absorbent articles 1 and the absorbent pads 50 may also constitute a group of products having the same brand name (a designation given to products with the same concept). That is, the absorbent article set 100 having the above configuration may be realized by combining corresponding absorbent articles 1 and absorbent pads 50 with the same brand name (and size). In this case, the user can easily obtain the absorbent articles 1 and absorbent pads 50 constituting the absorbent article set 100 using the same brand name as a marker (i.e., feel a sense of security by obtaining the above-described absorbent article set 100). For example, a brand name (e.g., "Lifree (registered trademark)") common to the absorbent article 1 and the absorbent pad 50 may be displayed on the absorbent article 1 itself (e.g., on the non-skin-facing side Z2 of the exterior body 10) or on a package containing one or more absorbent articles 1. Similarly, the common brand name may be displayed on the absorbent pad 50 itself or on a package containing one or more absorbent pads 50. [Explanation of symbols]
