When wearing the absorbent article, the outer cover is fitted to cover the wearer's torso, and the inner pad is placed on the skin-facing side of the crotch area of ​​the outer cover. The inner pad is removable from the outer cover and can be replaced as needed depending on the absorption status of urine and other excreted by the wearer. The absorbent article of the present invention is composed of this combination of an inner pad and an outer cover, with pockets provided on the skin-facing sides of the front and rear torso portions of the outer cover that open towards the center in the front-to-back direction, and fastening members provided on the outer surface of the inner pad, with the fastening members provided only in the central region in the front-to-back direction of the inner pad, and the fastening members of the inner pad are fastened to the skin-facing side of the crotch area of ​​the outer cover, and at least one of the front end and rear end of the inner pad is inserted into the pocket of the outer cover. With the inner pad and outer cover configured in this way, when using the inner pad by placing it on the skin-facing side of the outer cover, it becomes easier to set the inner pad on the skin-facing side of the crotch area of ​​the outer cover, and it also becomes easier to stably place the inner pad on the skin-facing side of the crotch area of ​​the outer cover. On the other hand, when replacing the inner pad, it can be easily removed from the outer cover.

[0010] Hereinafter, an absorbent article according to an embodiment of the present invention will be described with reference to the drawings. However, the present invention is not limited to the embodiments shown in the drawings. Figures 1 to 11 show examples of the configuration of an absorbent article according to an embodiment of the present invention. Figure 1 is a perspective view of the absorbent article, Figure 2 is a plan view of the absorbent article shown in Figure 1, with the front and rear body portions of the outer cover undone and unfolded, and the inner pad placed on the skin-facing side of the outer cover, as seen from the skin-facing side, Figure 3 is a III-III cross-sectional view of the absorbent article shown in Figure 2, Figures 4 to 8 are plan and cross-sectional views of the outer cover of the absorbent article shown in Figures 2 and 3, and Figures 9 to 11 are plan and cross-sectional views of the inner pad of the absorbent article shown in Figures 2 and 3.

[0011] The absorbent article 1 has an outer cover 11 and an inner pad 41 placed on the skin-facing side of the outer cover 11. The absorbent article 1 has a front-to-back direction y and a width direction x (see Figure 2). The front-to-back direction y means the direction extending in the front-to-back direction between the wearer's legs when the absorbent article 1 is worn by the wearer. The width direction x means the direction that lies on the same plane as the absorbent article 1 and is perpendicular to the front-to-back direction y, and corresponds to the left-to-right direction of the wearer when the absorbent article 1 is worn. Furthermore, the direction perpendicular to the plane formed by the front-to-back direction y and the width direction x is defined as the thickness direction z. In addition, when the absorbent article 1 is worn by the wearer, the side facing the wearer's skin is called the skin-facing side, and the opposite side is called the outer-facing side.

[0012] In the absorbent article 1, an inner pad 41 is placed on the skin-facing side of the outer cover 11. The outer cover 11 has a front torso portion 13, a rear torso portion 14, and a crotch portion 15 located between them in the front-to-back direction y, and is formed in the shape of pants. The outer cover 11 can be formed into the shape of pants having a waist opening 16 and a pair of leg openings 17 by joining the front torso portion 13 and the rear torso portion 14 at side seal portions 26 on both sides in the width direction x. The waist opening 16 is an opening for the wearer's torso to pass through, and the leg openings 17 are openings for the wearer's legs to pass through. The front torso portion 13 corresponds to the part that comes into contact with the wearer's abdomen when wearing the absorbent article 1, and the rear torso portion 14 corresponds to the part that comes into contact with the wearer's back when wearing the absorbent article 1. In the outer cover 11, the front torso portion 13 and the rear torso portion 14 correspond to the parts located between the waist opening 16 and the leg openings 17. The crotch area 15 is located between the front torso 13 and the rear torso 14, and corresponds to the part that comes into contact with the wearer's crotch. The crotch area 15 is located between the pair of leg openings 17 and is not joined to each other on either side in the width direction x.

[0013] The materials constituting the outer cover 11 are not particularly limited. Examples of materials constituting the outer cover 11 include nonwoven fabrics, woven fabrics, knitted fabrics, plastic films, and laminates thereof. When using fabric materials such as nonwoven fabrics, woven fabrics, or knitted fabrics as the constituent material of the outer cover 11, synthetic fibers such as polyolefins, polyesters, polyamides, and polyurethanes, or natural fibers such as pulp, cotton, and silk can be used as the fibers constituting the fabric material. When using plastic films as the constituent material of the outer cover 11, synthetic resins such as polyolefins, polyesters, polyamides, and polyurethanes can be used. The outer cover 11 may be permeable to liquids or impermeable to liquids.

[0014] The outer cover 11 preferably includes an absorbent core 23. If the outer cover 11 includes an absorbent core 23, even if urine or other fluids overflow from the inner pad 41, the overflowing urine or other fluids can be suitably absorbed by the outer cover 11.

[0015] As shown in Figures 4 to 7, the outer cover 11 equipped with an absorbent core 23 preferably comprises an outer covering member 12 positioned at least on the front torso portion 13 and the rear torso portion 14, and an absorbent body 20 positioned on the skin-facing side of the outer covering member 12 and at least on the crotch portion 15, wherein the absorbent body 20 is preferably configured with the absorbent core 23 positioned between the top sheet 21 and the back sheet 22. This makes it easy to form an outer cover 11 in the shape of pants and equipped with an absorbent core 23.

[0016] The absorbent body 20 only needs to be present in the crotch area 15, and preferably extends to at least a portion of the front torso 13 and / or rear torso 14. More preferably, the absorbent body 20 extends from the crotch area 15 to at least a portion of the front torso 13 and at least a portion of the rear torso 14. In the outer cover 11 shown in the drawing, the absorbent body 12 is positioned on the skin-facing side of the crotch area 15 of the outer cover member 12, which is formed in the shape of pants.

[0017] The top sheet 21 is positioned on the skin-facing side of the absorbent core 23 and is preferably permeable to liquids. The top sheet 21 can be, for example, a nonwoven fabric made from hydrophilic fibers such as cellulose, rayon, or cotton, or a nonwoven fabric made from hydrophobic fibers such as polyolefin (e.g., polypropylene, polyethylene), polyester (e.g., PET), or polyamide (e.g., nylon), in which the surface of the hydrophobic fibers has been made hydrophilic with a surfactant. Alternatively, woven fabric, knitted fabric, perforated plastic film, etc., may be used as the top sheet 21.

[0018] The backsheet 22 is positioned on the outer side of the absorbent core 23 and is preferably impermeable to liquids. The backsheet 22 can be made of, for example, a nonwoven fabric formed from hydrophobic fibers such as polyolefin (e.g., polypropylene, polyethylene), polyester (e.g., PET), or polyamide (e.g., nylon), or a plastic film. Alternatively, a laminate of nonwoven fabric and plastic film may be used.

[0019] When the top sheet 21 and back sheet 22 are made of nonwoven fabric, it is preferable to use spunbond nonwoven fabric, air-through nonwoven fabric, point-bond nonwoven fabric, meltblown nonwoven fabric, airlaid nonwoven fabric, SMS nonwoven fabric, etc. as the nonwoven fabric.

[0020] The absorbent core 23 is not particularly limited as long as it contains an absorbent material capable of absorbing excretions such as urine. As the absorbent core 23, for example, a molded body formed by molding an absorbent material into a predetermined shape can be used. The absorbent core 23 may be covered with a sheet member such as a paper sheet (e.g., tissue paper or thin paper) or a liquid-permeable nonwoven fabric. Examples of absorbent materials contained in the absorbent core 23 include hydrophilic fibers such as cellulose fibers (e.g., crushed pulp fibers), and superabsorbent resins such as polyacrylic acid-based, polyaspartic acid-based, cellulose-based, and starch-acrylonitrile-based resins. The absorbent material may also contain heat-weldable fibers such as polyolefin fibers such as polyethylene and polypropylene, polyester fibers such as PET, and polyamide fibers such as nylon. These heat-weldable fibers may be hydrophilized with surfactants or the like to increase their affinity for bodily fluids such as urine.

[0021] The absorbent material preferably contains hydrophilic fibers to increase the absorption rate of urine and other fluids. Furthermore, the absorbent material preferably contains a water-absorbent resin to increase its absorption capacity. Therefore, the absorbent core 23 preferably contains hydrophilic fibers (especially pulp fibers) and a water-absorbent resin. In this case, for example, it is preferable to use a material in which a water-absorbent resin is mixed or scattered on an aggregate of hydrophilic fibers.

[0022] The absorbent core 23 may be a sheet-shaped absorbent. An example of a sheet-shaped absorbent is one formed by having a water-absorbent resin between nonwoven fabrics and no pulp fibers. Because such a sheet-shaped absorbent has a water-absorbent resin between the nonwoven fabrics, it can achieve a high absorption capacity. Furthermore, because the sheet-shaped absorbent does not have pulp fibers between the nonwoven fabrics, it can be formed into a thin, non-bulky material.

[0023] The absorbent core 23 only needs to be present in the crotch area 15, and preferably extends to at least a portion of the front torso area 13 and / or at least a portion of the rear torso area 14.

[0024] The shape (planar shape) of the absorbent core 23 is not particularly limited. Examples of shapes for the absorbent core 23 include a roughly rectangular shape, an hourglass shape, a shuttlecock shape, etc. In the drawing, the absorbent core 23 is formed in a roughly rectangular shape.

[0025] Preferably, the absorbent body 20 is provided with upright flaps 24 on both sides in the width direction x on the skin side. The upright flaps 24 can prevent leakage of excretions such as urine from the sides. Preferably, the upright flaps 24 are impermeable to liquid. Preferably, the upright flaps 24 are provided with a flap elastic member 25 at the upper end (the end on the wearer's side) when they are raised, and the contractile force of the flap elastic member 25 promotes the upright positioning of the upright flaps 24.

[0026] An outer covering member 12 is provided on the outer surface of the absorbent body 20, and the outer covering member 12 is positioned on at least the front torso portion 13 and the rear torso portion 14. The outer covering member 12 is formed by joining the front torso portion 13 and the rear torso portion 14 to each other at side seal portions 26 on both sides in the width direction x, so that when the absorbent article 1 is worn, the outer covering member 12 of the outer cover 11 covers the wearer's torso. The side seal portions 26 are formed, for example, by joining the front torso portion 13 and the rear torso portion 14 to each other by welding on both sides in the width direction x.

[0027] In one embodiment, the exterior member 12 may be arranged only on the front body portion 13 and the rear body portion 14. In this case, the absorbent body 20 is provided so as to connect the front body portion 13 and the rear body portion 14 of the exterior member 12, and the absorbent body 20 extends from the crotch portion 15 to at least a part of the front body portion 13 and at least a part of the rear body portion 14, with a part of the absorbent body 20 exposed on the outer surface side of the absorbent article 1 at the crotch portion 15. In another embodiment, the exterior member 12 may be arranged on the front body portion 13, the crotch portion 15 and the rear body portion 14. The exterior member 12 may be formed by, for example, the front body portion 13, the rear body portion 14 and the crotch portion 15 located between them being continuous. In this case, the outer covering member 12 can be formed into a pant shape by joining the front torso portion 13 and the rear torso portion 14 to each other with the side seal portion 26, and the absorbent body 20 is provided on the skin-facing side of at least the crotch portion 15 of the outer covering member 12 formed into a pant shape. Alternatively, the outer covering member 12 may be separated in the front-rear direction y at the crotch portion 15 and consist of a portion extending from the front torso portion 13 to the crotch portion 15 and a portion extending from the rear torso portion 14 to the crotch portion 15, with the absorbent body 20 provided so as to connect the two portions. In the outer cover 11 shown in the drawing, the outer covering member 12 is formed into a pant shape.

[0028] It is preferable that the exterior member 12 extends outward in the width direction x than the absorbent body 20 at the front torso portion 13 and the rear torso portion 14. It is also preferable that the exterior member 12 extends outward in the width direction x than the absorbent body 20 at the crotch portion 15. Furthermore, it is preferable that the exterior member 12 extends outward in the front-rear direction y than the absorbent body 20, i.e., forward and backward.

[0029] The outer casing member 12 preferably has an inner sheet 18 and an outer sheet 19 disposed on the outer side of the inner sheet 18. The absorbent body 20 is preferably provided on the skin-facing side of the inner sheet 18. The inner sheet 18 and the outer sheet 19 may be permeable to liquid or impermeable to liquid, and sheet materials usable for the top sheet 21 and back sheet 22 can be used. In the drawing, the inner sheet 18 and the outer sheet 19 are each formed to have a pant shape, but if the outer casing member 12 is formed in a pant shape, it is sufficient that at least one of the inner sheet 18 and the outer sheet 19 is formed in a pant shape. For example, one of the inner sheet 18 and the outer sheet 19 may be provided separated in the front-rear direction y at the crotch area 15.

[0030] Preferably, the outer material 12 is provided with a leg elastic member 27 along the edge of the leg opening 17 (see Figure 7). The leg elastic member 27 is composed of, for example, a front leg elastic member 27A that crosses the crotch area 15 and is provided along the front edge of the leg opening 17, and a rear leg elastic member 27B that crosses the crotch area 15 and is provided along the rear edge of the leg opening 17. The front leg elastic member 27A and the rear leg elastic member 27B provide an elastic member around almost the entire circumference of the edge of the leg opening 17, forming leg gathers that conform to the wearer's legs and preventing leakage of urine, etc., from the crotch area. In Figure 7, the front leg elastic member 27A and the rear leg elastic member 27B are provided separated from each other in the front-rear direction y, but the front leg elastic member 27A and the rear leg elastic member 27B may be partially in contact with each other or may intersect. When the exterior member 12 is composed of an inner sheet 18 and an outer sheet 19, the leg elastic member 27 is preferably positioned between the inner sheet 18 and the outer sheet 19, and is also preferably bonded to the inner sheet 18 and / or the outer sheet 19.

More specifically, it is preferable that multiple torso elastic members 28A extending in the width direction x are provided on the front torso portion 13, and multiple torso elastic members 28B extending in the width direction x are provided on the rear torso portion 14. The torso elastic members 28 are provided between the waist opening 16 and the leg openings 17. The torso elastic members 28 improve the fit around the wearer's waist. Of the torso elastic members 28, elastic members provided at narrow intervals in the front-to-back direction y along the edge of the waist opening 16 may be provided as waist elastic members 29, which forms waist gathers that conform to the wearer's waist, preventing leakage of excretions such as urine from the back or abdomen. In the drawing, the waist elastic members 29 are provided at narrower intervals in the front-to-back direction y than the torso elastic members 28.

[0032] The torso elastic member 28 is preferably provided between the inner sheet 18 and the outer sheet 19. In this case, the torso elastic member 28 is preferably bonded to the inner sheet 18 and / or the outer sheet 19. The waist elastic member 29 may also be provided between the inner sheet 18 and the outer sheet 19, or the outer sheet 19 may be folded back towards the inner sheet 18 at the edge of the waist opening 16 of the outer material member 12, and the waist elastic member 29 may be provided between the folded outer sheet 19 (see Figure 6). In this case, the waist elastic member 29 is preferably bonded to the outer sheet 19.

The provision of these front and rear pockets allows the inner pad 41 to be stably positioned on the skin-facing side of the outer cover 11. The inner pad 41 can be stably positioned on the skin-facing side of the outer cover 11 by inserting its front and rear ends into at least one of the front pocket 32 ​​and the rear pocket 33. The "center in the front-to-back direction y" where the front pocket 32 ​​and the rear pocket 33 open refers to the center C1 side of the outer cover 11 in the front-to-back direction y. Hereinafter, in this specification, the front pocket 32 ​​and the rear pocket 33 may be collectively referred to as "pockets 32, 33". Furthermore, the front and rear ends of the inner pad 41 refer to the front and / or rear ends of the inner pad 41. Of the front and rear ends of the inner pad 41, the front end of the inner pad 41 is inserted into the front pocket 32, and the rear end of the inner pad 41 is inserted into the rear pocket 33.

[0035] The inner pad 41 is placed on the skin-facing side of the outer cover 11. If the outer cover 11 is composed of an outer covering member 12 and an absorbent body 20, as shown in the drawing, it is preferable that the inner pad 41 be placed on the skin-facing side of the absorbent body 20. The inner pad 41 is placed on at least the crotch area 15 of the outer cover 11. In Figure 2, it extends from the crotch area 15 of the outer cover 11 to the front torso area 13 and the rear torso area 14. The inner pad 41 is provided to receive and absorb urine and other fluids excreted by the wearer.

[0036] A fastening member 47 is provided on the outer surface of the inner pad 41. The fastening member 47 is provided to fix the inner pad 41 to the skin-facing side of the outer cover 11. By providing the fastening member 47 on the outer surface of the inner pad 41, the inner pad 41 can be attached to the skin-facing side of the outer cover 11 in a detachable manner for use.

[0037] As the fastening member 47, a hook member or adhesive layer of a hook-and-loop fastener can be used. The hook member of the hook-and-loop fastener is configured with multiple engaging elements protruding from the base, and is attached to the outer surface of the inner pad 41 such that the engaging elements face the outer surface of the inner pad 41. The shape of the engaging elements is not particularly limited and can be hook-shaped, anchor-shaped, mushroom-shaped, columnar, etc. The adhesive layer is attached to the outer surface of the inner pad 41 such that the adhesive layer faces the outer surface of the inner pad 41.

[0038] The fastening member 47 is provided in the central 2 / 4 region of the inner pad 41 in the front-rear direction y, but not in the front 1 / 4 region and the rear 1 / 4 region on either side. The central 2 / 4 region of the inner pad 41 in the front-rear direction y refers to the two central regions divided by dividing the inner pad 41 into four equal parts in the front-rear direction y. The fastening member 47 of the inner pad 41 is then fastened to the skin-facing side of the crotch area 15 of the outer cover 11, and the front end of the inner pad 41 is inserted into the front pocket 32, and / or the rear end of the inner pad 41 is inserted into the rear pocket 33. In Figure 2, the front end of the inner pad 41 is inserted into the front pocket 32, and the rear end of the inner pad 41 is inserted into the rear pocket 33.

[0039] The absorbent article 1 is constructed by combining an inner pad 41 and an outer cover 11 as described above. When the inner pad 41 is placed on the skin-facing side of the outer cover 11, it becomes easier to set the inner pad 41 on the skin-facing side of the crotch area 15 of the outer cover 11, and it also becomes easier to stably install the inner pad 41 on the crotch area 15 of the outer cover 11. Specifically, the inner pad 41 can be stably attached to the crotch area 15 of the outer cover 11 by fastening a fastening member 47 provided in the central region of the front-rear direction y on the outer surface of the inner pad 41 to the skin-facing side of the crotch area 15 of the outer cover 11, and by inserting at least one of the front end and rear end of the inner pad 41 into the pockets 32, 33 of the outer cover 11. Furthermore, since the fastening members 47 are not provided at the front and rear ends of the inner pad 41, it becomes easy to insert the front and rear ends of the inner pad 41 into the pockets 32 and 33 of the outer cover 11, and it becomes easy to set the inner pad 41 on the skin-facing side of the crotch area 15 of the outer cover 11. In addition, it becomes easy to pull out the front and rear ends of the inner pad 41 from the pockets 32 and 33, and when replacing the inner pad 41, it can be easily removed from the outer cover 11.

[0040] To enhance the effects described above, it is preferable that the fastening member 47 is provided in the central 2 / 5 region of the inner pad 41 in the front-rear direction y, and not in the front 3 / 10 region and the rear 3 / 10 region, and more preferably that it is provided in the central 1 / 3 region of the inner pad 41 in the front-rear direction y, and not in the front 1 / 3 region and the rear 1 / 3 region. Furthermore, it is preferable that both the front and rear ends of the inner pad 41 are inserted into the pockets 32 and 33 of the outer cover 11, that is, the front end of the inner pad 41 is inserted into the front pocket 32 ​​and the rear end is inserted into the rear pocket 33.

[0041] In the absorbent article 1, a fastening member 47 is provided on the outer surface of the inner pad 41, but it is preferable that no fastening members are provided inside the pockets 32 and 33 of the outer cover 11. This makes it easy to insert the front and rear ends of the inner pad 41 into the pockets 32 and 33 of the outer cover 11 and to pull them out of the pockets 32 and 33. It is also preferable that no fastening members are provided on the skin-facing side of the crotch area 15 of the outer cover 11, for example, it is preferable that no fastening members are provided on the skin-facing side of the absorbent body 20.

[0042] The shape of the inner pad 41 is not particularly limited. Examples of inner pad shapes include rectangles (including rounded rectangles), hourglass shapes, and shuttlecock shapes. However, from the viewpoint of ease of manufacturing, it is preferable that the inner pad 41 be formed in a substantially rectangular shape.

[0043] The inner pad 41 is preferably formed to be longer in the front-to-back direction y than in the width direction x. For example, the length of the inner pad 41 in the front-to-back direction y is preferably 2.0 times or more the length of the width direction x, more preferably 2.5 times or more, even more preferably 3.0 times or more, and preferably 5.0 times or less, more preferably 4.5 times or less, and even more preferably 4.0 times or less. The length of the inner pad 41 in the front-to-back direction y is preferably 25 cm or more, more preferably 30 cm or more, even more preferably 35 cm or more, and preferably 60 cm or less, more preferably 55 cm or less, and even more preferably 50 cm or less. The length of the inner pad 41 in the front-to-back direction y is preferably shorter than the length of the outer cover 11 in the front-to-back direction y from the front end of the front pocket 32 ​​to the rear end of the rear pocket 33.

[0044] The shape (planar shape) of the fastening member 47 is not particularly limited. Examples of fastening member 47 shapes include squares, circles, ellipses, polygons other than squares, and irregular shapes. Only one fastening member 47 may be provided on the outer surface of the inner pad 41, or multiple fastening members may be provided.

[0045] The fastening member 47 is preferably a hook member of a hook-and-loop fastener. If the fastening member 47 is a hook member of a hook-and-loop fastener, even if the fastening member 47 is fastened to an unintended location on the outer cover 11, the fastening member 47 can be detached from the outer cover 11, the inner pad 41 can be repositioned appropriately, and the fastening member 47 can be fastened again to the desired location on the outer cover 11. This makes it easy to attach the inner pad 41 to the desired location on the outer cover 11. Among these, a hook member having a columnar engaging element is particularly preferred, as this allows the fastening member 47 to be easily detached from the outer cover 11 even if it is fastened to an unintended location on the outer cover 11.

[0046] The inner pad 41 preferably includes an absorbent core 44, and is preferably configured such that the absorbent core 44 is positioned between the top sheet 42 and the back sheet 43, as shown in Figures 9 to 11. Details of the top sheet 42, back sheet 43 and absorbent core 44 of the inner pad 41 are described in the above-described explanation of the top sheet 21, back sheet 22 and absorbent core 23 of the outer cover 11. The inner pad 41 may also be provided with rising flaps 45 on both sides in the width direction x on the skin side, and details of the rising flaps 45 of the inner pad 41 are described in the above-described explanation of the rising flaps 24 of the outer cover 11. The rising flaps 45 preferably have a flap elastic member 46 at the upper end (the end on the wearer side) when they are raised, and the contraction force of the flap elastic member 46 promotes the raising of the rising flaps 45.

[0047] The width (length in the width direction x) of the inner pad 41 is preferably narrower than the opening width W1 of the front pocket 32 ​​and the opening width W2 of the rear pocket 33. This makes it easier to insert the front and rear ends of the inner pad 41 into the front pocket 32 ​​and the rear pocket 33.

[0048] The pockets 32 and 33 of the outer cover 11 can be formed by providing cover sheets 30 and 31 on the skin-facing side of the exterior member 12. Specifically, the front pocket 32 ​​can be formed by providing the front cover sheet 30 on the skin-facing side of the front body portion 13 of the exterior member 12, and the rear pocket 33 can be formed by providing the rear cover sheet 31 on the skin-facing side of the rear body portion 14 of the exterior member 12. This will be explained in detail with reference to Figure 8. Figure 8 shows an example of the formation of a joining region in which the front cover sheet 30 and the rear cover sheet 31 are joined to the exterior member 12 for the outer cover 11 shown in Figure 4. In Figure 8, the joining regions of the front cover sheet 30 and the rear cover sheet 31 to the exterior member 12 are shown with cross-hatching, and the outer edges of the front pocket 32 ​​and the rear pocket 33 are shown with dashed lines. Also, for ease of understanding, the elastic members are omitted from the diagram.

[0049] A front cover sheet 30 is provided on the skin-facing side of the front body portion 13 of the exterior member 12. The front cover sheet 30 has a bonding region 30A that is bonded to the exterior member 12 and a non-bonding region 30B that is not bonded to either the exterior member 12 or the absorbent body 20. The non-bonding region 30B extends forward from the rear edge 30E of the front cover sheet 30, forming a front pocket 32 ​​with the rear edge 30E of the front cover sheet 30 as the opening edge 32E. A rear cover sheet 31 is provided on the skin-facing side of the rear body portion 14 of the exterior member 12. The rear cover sheet 31 has a bonding region 31A that is bonded to the exterior member 12 and a non-bonding region 31B that is not bonded to either the exterior member 12 or the absorbent body 20. The non-bonding region 31B extends rearward from the front edge 31E of the rear cover sheet 31, forming a rear pocket 33 with the front edge 31E of the rear cover sheet 31 as the opening edge 33E. By providing the front cover sheet 30 and the rear cover sheet 31 in this manner, the front pocket 32 ​​and the rear pocket 33 can be easily formed. Although not shown in the drawings, the joining area 30A of the front cover sheet 30 may be formed to join with the exterior member 12, or in place of the exterior member 12, to at least a part of the absorbent body 20, and the joining area 31A of the rear cover sheet 31 may be formed to join with the exterior member 12, or in place of the exterior member 12, to at least a part of the absorbent body 20. In this specification, the front cover sheet 30 and the rear cover sheet 31 may be collectively referred to as "cover sheets 30, 31".

[0050] In the joining area 30A of the front cover sheet 30 and the joining area 31A of the rear cover sheet 31, the means of joining the cover sheets 30, 31 to the exterior member 12 and / or absorbent body 20 are not particularly limited, and known joining means such as welding (e.g., heat sealing or ultrasonic welding) or adhesives can be used. For simplicity, the cover sheets 30, 31 are joined to at least a part of the exterior member 12 and / or absorbent body 20 by adhesive.

[0051] The front pocket 32 ​​is formed by the non-jointed region 30B of the front cover sheet 30 extending forward from the rear edge 30E of the front cover sheet 30 by a predetermined width or more (for example, 50 mm or more or 80 mm or more). At the opening of the front pocket 32, jointed regions 30A exist on both sides of the non-jointed region 30B of the front cover sheet 30 in the width direction x, and the rearmost part of the non-jointed region 30B located between these two jointed regions 30A becomes the opening of the front pocket 32, and the length of this part in the width direction x becomes the opening width W1 of the front pocket 32. A jointed region 30A exists at the front end of the front pocket 32, and the length from the opening edge 32E to the front end of the front pocket 32 ​​becomes the depth of the front pocket 32. The non-jointed region 30B that forms the front pocket 32 ​​may be formed with a constant width extending forward from the rear edge 30E of the front cover sheet 30, or it may be formed so that its width varies.

[0052] The rear pocket 33 is formed by the non-jointed region 31B of the rear cover sheet 31 extending rearward from the front edge 31E of the rear cover sheet 31 by a predetermined width or more (for example, 50 mm or more or 80 mm or more). At the opening of the rear pocket 33, jointed regions 31A exist on both sides of the non-jointed region 31B of the rear cover sheet 31 in the width direction x. The foremost part of the non-jointed region 31B located between these two jointed regions 31A becomes the opening of the rear pocket 33, and the length of this part in the width direction x becomes the opening width W2 of the rear pocket 33. A jointed region 31A exists at the rear end of the rear pocket 33, and the length from the opening edge 33E to the rear end of the rear pocket 33 is the depth of the rear pocket 33. The non-jointed region 31B forming the rear pocket 33 may be formed with a constant width from the front edge 31E of the rear cover sheet 31 toward the rear, or it may be formed with a variable width.

[0053] Although not shown in the drawings, pockets 32 and 33 can also be formed by folding the sheet material constituting the exterior member 12 toward the skin side, and using the folded portion as the cover sheet 30 and 31 described above. For example, the outer sheet 19 constituting the exterior member 12 can be folded toward the skin side at the edge of the waist opening 16, and a part of this folded portion can be joined to the inner sheet 18 and / or absorbent body 20 to form the joined areas 30A and 31A, while the remaining portion can not be joined to either the inner sheet 18 or the absorbent body 20 to form the unjoined areas 30B and 31B. Alternatively, the inner sheet 18 constituting the exterior member 12 can be folded toward the skin side, and a part of this folded portion can be joined to the opposing inner sheet 18 and / or absorbent body 20 to form the joined areas 30A and 31A, while the remaining portion can not be joined to either the opposing inner sheet 18 or the absorbent body 20 to form the unjoined areas 30B and 31B.

[0054] Preferably, the opening edge 32E of the front pocket 32 ​​is positioned to overlap with the absorbent core 23 of the outer cover 11, and the front end of the inner pad 41 is inserted into the front pocket 32, and / or, the opening edge 33E of the rear pocket 33 is positioned to overlap with the absorbent core 23 of the outer cover 11, and the rear end of the inner pad 41 is inserted into the rear pocket 33. This makes it easier to insert the front and rear ends of the inner pad 41 into the pockets 32 and 33. Also, when the front and rear ends of the inner pad 41 are inserted into the pockets 32 and 33, the front and rear ends of the inner pad 41 are supported by the absorbent core 23, making it difficult for the front and rear ends of the inner pad 41 to come out of the pockets 32 and 33 unintentionally. Therefore, the inner pad 41 can be stably installed on the skin-facing side of the crotch area 15 of the outer cover 11. More preferably, both the opening edge 32E of the front pocket 32 ​​and the opening edge 33E of the rear pocket 33 are positioned to overlap with the absorbent core 23. It is more preferable that the front pocket 32 ​​is provided so as to extend forward from a position overlapping with the absorbent core 23 and beyond the front end of the absorbent core 23. It is more preferable that the rear pocket 33 is provided so as to extend backward from a position overlapping with the absorbent core 23 and beyond the rear end of the absorbent core 23.

[0055] The positions of pockets 32, 33 and absorbent cores 23 are defined by unfastening the joint between the front body portion 13 and the rear body portion 14 of the exterior member 12 at the side seal portion 26 and unfolding the outer cover 11, which is then fully extended. For example, the outer cover 11 is unfolded in this manner, and the elastic members provided on the outer cover 11 are cut into small pieces to prevent the elastic members from contracting, and then the outer cover 11 is fully extended to define each position. Each drawing shows a plan view, cross-sectional view, etc., of the outer cover 11 in its fully extended state.

[0056] The opening width W1 of the front pocket 32 ​​and / or the opening width W2 of the rear pocket 33 is preferably 70% or more of the width of the absorbent core 23, more preferably 80% or more, and even more preferably 90% or more. The opening width W1 of the front pocket 32 ​​and the opening width W2 of the rear pocket 33 may be wider than the width of the absorbent core 23. On the other hand, the upper limit of the opening width W1 of the front pocket 32 ​​and the opening width W2 of the rear pocket 33 is preferably 200% or less of the width of the absorbent core 23, more preferably 180% or less, and even more preferably 150% or less. This makes it easier to insert the front and rear ends of the inner pad 41 into the pockets 32 and 33, and makes it easier to stably hold the inner pad 41 in the pockets 32 and 33. The width of the absorbent core 23 as described here refers to the length in the width direction x of the absorbent core 23 at the position where the opening of the front pocket 32 ​​or the opening of the rear pocket 33 overlaps with the absorbent core 23 (more specifically, the length in the width direction x of the absorbent core 23 at the position where the opening of the front pocket 32 ​​or the opening of the rear pocket 33 overlaps with the absorbent core 23 in the front-to-back direction y), if the opening of the front pocket 32 ​​is located in front of the front end of the absorbent core 23, it refers to the length in the width direction x of the front end of the absorbent core 23, and if the opening of the rear pocket 33 is located behind the rear end of the absorbent core 23, it refers to the length in the width direction x of the rear end of the absorbent core 23.

[0057] The opening width W1 of the front pocket 32 ​​and / or the opening width W2 of the rear pocket 33 is preferably wider than the width of the absorbent core 23, and more preferably wider than the width of the absorbent body 20. Furthermore, the opening edge 32E of the front pocket 32 ​​is formed to overlap with the absorbent core 23, and the opening width W1 of the front pocket 32 ​​is preferably wider than the width of the absorbent core 23 at the position overlapping with the opening of the front pocket 32, and more preferably wider than the width of the absorbent body 20 at the position overlapping with the opening of the front pocket 32. Similarly, the opening edge 33E of the rear pocket 33 is formed to overlap with the absorbent core 23, and the opening width W2 of the rear pocket 33 is preferably wider than the width of the absorbent core 23 at the position overlapping with the opening of the rear pocket 33, and more preferably wider than the width of the absorbent body 20 at the position overlapping with the opening of the rear pocket 33.

[0058] The front cover sheet 30 is provided on at least the front torso portion 13, and may extend from the front torso portion 13 to the crotch portion 15. Therefore, the opening edge 32E of the front pocket 32 ​​may be located on the front torso portion 13 or on the crotch portion 15. The front cover sheet 30 may be provided on the entire front torso portion 13 or on only a part of the front torso portion 13. The front cover sheet 30 is preferably wider than the absorbent body 20 in the width direction x, and it is preferable that the length in the width direction x is substantially the same as that of the front torso portion 13 of the exterior member 12.

[0059] The rear cover sheet 31 is provided on at least the rear torso portion 14, and may extend from the rear torso portion 14 to the crotch portion 15. Therefore, the opening edge 33E of the rear pocket 33 may be located on the rear torso portion 14 or on the crotch portion 15. The rear cover sheet 31 may be provided on the entire rear torso portion 14 or on only a part of the rear torso portion 14. The rear cover sheet 31 is preferably wider than the absorbent body 20 in the width direction x, and it is more preferably formed to have a length in the width direction x that is substantially the same as that of the rear torso portion 14 of the exterior member 12.

[0060] It is preferable that the front cover sheet 30 and / or the rear cover sheet 31 are not joined to the absorbent body 20, and it is more preferable that both the front cover sheet 30 and the rear cover sheet 31 are not joined to the absorbent body 20. Accordingly, it is preferable that the joining area 30A of the front cover sheet 30 is formed to join the front cover sheet 30 to the exterior member 12, and it is preferable that the joining area 31A of the rear cover sheet 31 is formed to join the rear cover sheet 31 to the exterior member 12. This makes it easier to insert the front and rear ends of the inner pad 41 into the pockets 32 and 33.

[0061] The cover sheets 30 and 31 may be permeable (hydrophilic) or impermeable, and sheet materials usable for the top sheet 21 and back sheet 22 can be used. For example, if the cover sheets 30 and 31 are permeable, even if urine or other fluids are excreted on the cover sheets 30 and 31, the urine or other fluids can pass through the cover sheets 30 and 31, allowing a wider area of ​​the inner pad 41 to contribute to the absorption of urine or other fluids. In this case, both the front cover sheet 30 and the rear cover sheet 31 may be permeable, or only one of them may be permeable, but it is preferable that at least the front cover sheet 30 is permeable. On the other hand, if the cover sheets 30 and 31 are impermeable, the cover sheets 30 and 31 can prevent leakage of urine or other fluids from the ventral or dorsal side.

[0062] Preferably, the front pocket 32 ​​is provided with an elastic member 34 for the front pocket 34 along the opening edge 32E of the front pocket 32. Similarly, preferably, the rear pocket 33 is provided with an elastic member 35 for the rear pocket 35 along the opening edge 33E of the rear pocket 33. The elastic member 34 for the front pocket is preferably provided on the front cover sheet 30 along the rear edge 30E of the front cover sheet 30, overlapping at least the non-jointed region 30B that forms the front pocket 32. The elastic member 34 for the front pocket is also preferably fixed to the front cover sheet 30 in an extended state. The elastic member 35 for the rear pocket is preferably provided on the rear cover sheet 31 along the front edge 31E of the rear cover sheet 31, overlapping at least the non-jointed region 31B that forms the rear pocket 33. The elastic member 35 for the rear pocket is also preferably fixed to the rear cover sheet 31 in an extended state. By providing the front pocket elastic member 34 and the rear pocket elastic member 35, when the front and rear ends of the inner pad 41 are inserted into the pockets 32 and 33, the front and rear ends of the inner pad 41 are held in place by the front pocket elastic member 34 and the rear pocket elastic member 35. As a result, the front and rear ends of the inner pad 41 are less likely to come out of the pockets 32 and 33, and the inner pad 41 can be stably installed on the skin-facing side of the outer cover 11. Therefore, it is preferable that the outer cover 11 has the front pocket elastic member 34 along the opening edge 32E of the front pocket 32, with the front end of the inner pad 41 inserted into the front pocket 32, and / or the rear pocket elastic member 35 along the opening edge 33E of the rear pocket 33, with the rear end of the inner pad 41 inserted into the rear pocket 33. More preferably, the outer cover 11 is provided with an elastic member 34 for the front pocket and an elastic member 35 for the rear pocket along the opening edge 32E of the front pocket 32 ​​and the opening edge 33E of the rear pocket 33, respectively, and the front and rear ends of the inner pad 41 are inserted into the front pocket 32 ​​and the rear pocket 33, respectively. Hereinafter, the elastic member 34 for the front pocket and the elastic member 35 for the rear pocket may be collectively referred to as "elastic members 34 and 35 for the pockets".

[0063] It is preferable that the elastic member 34 for the front pocket is provided to be longer in the width direction x than the opening width W1 of the front pocket 32. That is, it is preferable that the elastic member 34 for the front pocket extends outward in the width direction x than both ends of the opening of the front pocket 32. It is preferable that the elastic member 35 for the rear pocket is provided to be longer in the width direction x than the opening width W2 of the rear pocket 33. That is, it is preferable that the elastic member 35 for the rear pocket extends outward in the width direction x than both ends of the opening of the rear pocket 33. With the pocket elastic members 34 and 35 provided in this way, when the front and rear ends of the inner pad 41 are inserted into the pockets 32 and 33, the front and rear ends of the inner pad 41 are held down by the pocket elastic members 34 and 35 over the entire width direction x, making it difficult for the front and rear ends of the inner pad 41 to come out of the pockets 32 and 33 unintentionally.

[0064] The number of elastic members 34 for the front pocket may be one or more. The number of elastic members 35 for the rear pocket may be one or more. Preferably, multiple elastic members 34 for the front pocket are provided along the opening edge 32E of the front pocket 32, and multiple elastic members 35 for the rear pocket are provided along the opening edge 33E of the rear pocket 33. When multiple elastic members 34 for the front pocket and multiple elastic members 35 for the rear pocket are provided in this manner, the front and rear ends of the inner pad 41 are pressed down in a planar manner by the multiple elastic members 34 for the front pocket or the multiple elastic members 35 for the rear pocket, and the front and rear ends of the inner pad 41 are held more stably inside the pockets 32 and 33.

[0065] It is preferable that the pocket elastic members 34 and 35 are arranged to overlap with the absorbent core 23. This ensures that when the front and rear ends of the inner pad 41 are inserted into the pockets 32 and 33, the front and rear ends of the inner pad 41 are sandwiched between the absorbent core 23 and the pocket elastic members 34 and 35, making it easier to stably hold them within the pockets 32 and 33. If multiple pocket elastic members 34 and 35 are provided, it is preferable that one or more of the pocket elastic members 34 and 35 are arranged to overlap with the absorbent core 23.

[0066] Preferably, the elastic member 34 for the front pocket is positioned in the front pocket 32, for example, in the 1 / 2 area on the side of the opening edge 32E, and not in the 1 / 2 area on the back side of the front pocket 32. This makes it easier to insert the front end of the inner pad 41 into the front pocket 32, allowing it to reach the back of the pocket. More preferably, the elastic member 34 for the front pocket is positioned in the front pocket 32, in the 1 / 3 area on the side of the opening edge 32E, and not in the 2 / 3 area on the back side of the front pocket 32.

[0067] Preferably, the elastic member 35 for the rear pocket is positioned in the rear pocket 33, for example, in the 1 / 2 area on the side of the opening edge 33E, and not in the 1 / 2 area on the back side of the rear pocket 33. This makes it easier to insert the rear end of the inner pad 41 into the rear pocket 33, allowing it to reach the back of the pocket. More preferably, the elastic member 35 for the rear pocket is positioned in the rear pocket 33, in the 1 / 3 area on the side of the opening edge 33E, and not in the 2 / 3 area on the back side of the rear pocket 33.

[0068] As shown in Figure 4, it is preferable that the narrowest part C2 of the crotch area 15 of the outer cover 11 is located in front of the center C1 in the front-to-back direction y of the outer cover 11. With the outer cover 11 configured in this way, the wearer can move their legs back and forth more easily. In addition, the inner pad 41 placed on the skin-facing side of the crotch area 15 of the outer cover 11 is less likely to swing from side to side due to the back-and-forth movement of the wearer's legs. As a result, the front and rear ends of the inner pad 41 are less likely to come out of the pockets 33, 34 unintentionally, and the inner pad 41 can be stably installed on the skin-facing side of the crotch area 15 of the outer cover 11.

[0069] The outer cover 11 is provided with the front leg elastic member 27A and the rear leg elastic member 27B spaced apart from each other in the front-rear direction y in the portion where they cross the crotch area 15, and the fastening member 47 of the inner pad 41 is preferably fastened to the skin-facing side of the absorbent body 20 at a position overlapping with the front-rear direction y shown by reference numeral 36 in Figure 7, that is, the portion where the front leg elastic member 27A crosses the crotch area 15, the portion where the rear leg elastic member 27B crosses the crotch area 15, or the portion in between these. By fastening the fastening member 47 of the inner pad 41 to the skin-facing side of the absorbent body 20 in this way, the inner pad 41 can be stably installed on the skin-facing side of the crotch area 15 of the outer cover 11. In the outer cover 11, the portion where the front leg elastic member 27A crosses the crotch area 15, the portion where the rear leg elastic member 27B crosses the crotch area 15, or the portion between these, is less affected by the positional fluctuations in the front-to-back direction y due to the contraction force of the front leg elastic member 27A and the rear leg elastic member 27B, and the position in the front-to-back direction y is relatively stable. Therefore, by fastening the fastening member 47 of the inner pad 41 to a position that overlaps with such portions, the inner pad 41 can be stably installed on the skin-facing side of the crotch area 15 of the outer cover 11.

[0070] It is preferable that the front leg elastic member 27A and the rear leg elastic member 27B are provided intermittently in the portion that crosses the crotch area 15. In this case, the contractile force of the front leg elastic member 27A and the rear leg elastic member 27B is lost in the portion that crosses the crotch area 15. Therefore, when the fastening member 47 of the inner pad 41 is fastened to the absorbent body 20 at a position that overlaps with the portion where the front leg elastic member 27A crosses the crotch area 15, the portion where the rear leg elastic member 27B crosses the crotch area 15, or the portion in between these, the inner pad 41 can be installed more stably on the skin-facing side of the crotch area 15 of the outer cover 11.

[0071] When the front leg elastic member 27A and the rear leg elastic member 27B are provided intermittently across the crotch area 15, the front leg elastic member 27A and the rear leg elastic member 27B can be bonded and fixed to the exterior member 12 (specifically, the inner sheet 18 and / or outer sheet 19), and then the front leg elastic member 27A and the rear leg elastic member 27B can be cut with a cutter or the like. In this way, the front leg elastic member 27A and the rear leg elastic member 27B can be provided intermittently in an easy manufacturing manner.

[0072] As shown in Figures 2 and 3, it is preferable that the outer cover 11 is equipped with a rising flap 24 (hereinafter referred to as the "outer rising flap"), and the inner pad 41 is also equipped with a rising flap 45 (hereinafter referred to as the "inner rising flap"). Furthermore, when the inner pad 41 is placed on the skin-facing side of the crotch area 15 of the outer cover 11, it is preferable that the inner rising flap 45 is positioned inward in the width direction x compared to the outer rising flap 24. This allows both the inner rising flap 45 and the outer rising flap 24 to effectively prevent lateral leakage of urine, etc., when urine, etc., is excreted on the inner pad 41.

[0073] In the above case, it is preferable that the standing height of the inner rising flap 45 is higher than the standing height of the outer rising flap 24 at the narrowest part C2 of the crotch area 15 of the outer cover 11. This makes it less likely for urine, etc., to flow over the inner rising flap 45 onto the outer cover 11 when it is excreted on the inner pad 41, and makes it easier to keep the urine, etc. on the inner pad 41. Therefore, it becomes easier to reuse the outer cover 11 and replace only the inner pad 41.

[0074] The inner pad 41 preferably has an hourglass-shaped absorbent core 44, and both side edges of the inner pad 41 in the width direction x are formed in a straight line extending in the front-rear direction y within the range of the front-rear direction y where the absorbent core 44 exists (see Figures 9 and 10). By forming the inner pad 41 in this way, the upright height of the rising flap 45 of the inner pad 41 can be made higher.

[0075] As an hourglass-shaped absorbent core 44, the absorbent core 44 has a front portion 44A, a rear portion 44C, and an intermediate portion 44B between them in the front-rear direction y, and it is preferable that the intermediate portion 44B is formed to be narrower than the front portion 44A and the rear portion 44C. The absorbent core 44 is formed to be widest at the front portion 44A and / or the rear portion 44C. The length in the width direction x of the front portion 44A and the length in the width direction x of the rear portion 44C may be the same or different.

[0076] In the absorbent core 44, the front portion 44A includes the widest part of the front half of the absorbent core 44 and can be defined as the portion in front of that part, and the rear portion 44C includes the widest part of the rear half of the absorbent core 44 and can be defined as the portion in rear of that part. The intermediate portion 44B of the absorbent core 44 can be defined as the portion behind the widest part of the front half of the absorbent core 44 and in front of the widest part of the rear half of the absorbent core 44.

[0077] The absorbent core 44 preferably has portions in the front portion 44A and the rear portion 44C where the length in the width direction x is constant. Therefore, the outer edge of the absorbent core 44 preferably has a straight portion extending in the front-rear direction y in the front portion 44A and the rear portion 44C. The absorbent core 44 may have portions in the middle portion 44B where the length in the width direction x is constant, but it is preferable that one side of the middle portion 44B in the front-rear direction y has a portion where the width gradually increases toward the front portion 44A, and the other side of the middle portion 44B in the front-rear direction y has a portion where the width gradually increases toward the rear portion 44C.

[0078] Preferably, the inner pad 41 has both side edges in the width direction x that extend in a straight line in the front-to-back direction x within the range in the front-to-back direction y where the absorbent core 44 exists, and has a margin portion 48 where the absorbent core 44 does not exist, extending outward in the width direction x from the middle portion 44B of the absorbent core 44. In this case, the margin portion 48 will consist of the top sheet 42 and / or the back sheet 43. When the absorbent article 1 is used, the margin portion 48 of the inner pad 41 will fold toward the wearer's skin, allowing the standing height of the inner standing flap 45 to be formed to be higher. Preferably, the margin portion 48 is not substantially formed outward in the width direction x from the front portion 44A and the rear portion 44C of the absorbent core 44.

[0079] Preferably, the inner pad 41 has a top sheet 42 or a back sheet 43 that is folded back along both side edges in the width direction x of the front portion 44A and rear portion 44C of the absorbent core 44. Specifically, it is preferable that both sides of the top sheet 42 in the width direction x are folded back toward the outer surface side of the absorbent core 44 along both side edges in the width direction x of the front portion 44A and rear portion 44C of the absorbent core 44, or that both sides of the back sheet 43 in the width direction x are folded back toward the skin side of the absorbent core 44 along both side edges in the width direction x of the front portion 44A and rear portion 44C of the absorbent core 44. This makes it easy to form the side edges of the inner pad 41 in the width direction x into a straight line extending in the front-to-back direction y. In addition, even if the wearer's legs come into contact with both end edges of the inner pad 41 in the width direction x, the wearer is less likely to feel discomfort or pain. In Figure 11, both sides of the backsheet 43 in the width direction x are folded back towards the skin side of the absorbent core 44, and the top sheet 42 is joined to both sides of the folded backsheet 43 in the width direction x.

[0080] When the absorbent core 44 of the inner pad 41 is formed in an hourglass shape, it is preferable that the fastening member 47 be provided in a position that overlaps with the middle portion 44B of the absorbent core 44. By providing the fastening member 47 in such a position, the inner pad 41 can be stably installed on the skin-facing side of the crotch portion 15 of the outer cover 11. [Explanation of Symbols]
