FIG. 3 is a conceptual plan view of the pad P. FIG. 4 is a schematic plan view of the diaper 1 in the unfolded state. FIG. 5 is a schematic cross-sectional view of the diaper 1 in the unfolded state. FIG. 6 is a schematic longitudinal sectional view of the diaper 1 in the unfolded state. FIG. 7 is a diagram in which only the separate backside band member 40 is taken out from FIG. 4, and is a schematic plan view of the separate backside band member 40 provided in the diaper 1. FIG. 8 is a diagram in which only the separate abdominal band member 45 is taken out from FIG. 4, and is a schematic plan view of the separate abdominal band member 45 provided in the diaper 1.

  A disposable diaper (hereinafter also simply referred to as diaper 1) as an example of an absorbent article according to the present embodiment is a disposable diaper mainly intended for wearing by adults, and is used particularly in a nursing facility or the like.

  Moreover, it is assumed that the diaper 1 inserts and uses the pad P (refer FIG. 3). Like the diaper 1, this pad P is an absorbent body covered with a non-woven fabric, and is used by being inserted between the diaper 1 and the wearer's skin. And if the pad P is not inserted and the diaper 1 is used alone, the diaper 1 must be replaced every time the excrement is excreted, but the diaper 1 is inserted with the pad P inserted. When used, since excrement is absorbed mainly by the absorbent body of the pad P when excrement is excreted, it is sufficient to replace only the pad P. Therefore, when the pad P is used, it is not necessary to replace the diaper 1 every time excrement is excreted, and the diaper 1 can be used for a long time.

  In the following description, the longitudinal direction, the lateral direction, and the thickness direction of the diaper 1 are simply referred to as “vertical direction”, “lateral direction”, and “thickness direction”, respectively. Regarding the thickness direction, the side in contact with the wearer is also referred to as “skin side” or “inside”, and the opposite side is also referred to as “non-skin side” or “outside”. In the following description, “lateral direction” is also referred to as “width direction”.

  The diaper 1 according to the present embodiment has a vertical direction, a horizontal direction, and a thickness direction as three directions intersecting (orthogonal) with each other. Moreover, the diaper 1 is what is called a 3 piece type, and has three components. That is, this diaper 1 has an absorbent main body 10 that is applied to the crotch part of the wearer and absorbs excrement such as urine as the first part, and the abdomen part of the wearer as the second part. It has an abdominal band member 20 that covers it, and a back band member 30 that covers the back side of the wearer as a third part.

  Furthermore, in the diaper 1 according to the present embodiment, as the fourth and fifth parts, a separate back side belt member 40 and a separate body different from the absorbent main body 10, the abdominal side belt member 20, and the back side belt member 30. A ventral belt member 45 is added to the three parts. These separate band members are provided to maintain the pad P inserted into the diaper 1 in an appropriate position (to be described in detail later), and the separate back side band member 40 is the back side band member 30. In the vertical direction, it is positioned closer to the center side of the absorbent main body 10 than the dorsal belt member 30 in the vertical direction, and the separate ventral belt member 45 is overlapped with the ventral belt member 20 in the vertical direction. It is located on the center side of the absorbent main body 10 relative to the ventral band member 20.

  In the unfolded state of FIG. 4, the back side band member 30 on which the separate back side band member 40 is overlapped and the abdominal side band member 20 on which the separate abdominal side band member 45 is stacked are arranged in parallel with a vertical interval therebetween. In the state, the absorptive main body 10 is stretched between them. And the back | dorsal band member 30 is fixed to the one end part 10a in the vertical direction of the absorptive main body 10, and the ventral | abdominal band member 20 is being fixed to the other end part 10b, and the external appearance has comprised the planar view substantially H shape.

  And from this state, the absorptive main body 10 is folded in half with the substantially central portion in the longitudinal direction (that is, the longitudinal direction) as the folding position. When the ventral band member 20 and the dorsal band member 30 that are opposed to each other in the folded state are joined and connected, the band members are formed in an annular shape. That is, the diaper 1 is formed by joining both edge portions 30 a in the lateral direction of the back band member 30 and both edge portions 20 a in the lateral direction of the ventral band member 20. Thereby, it becomes the diaper 1 of the wearing condition in which the trunk periphery opening 1a and a pair of leg periphery opening 1b as shown in FIG. 1 were formed.

  Hereinafter, the five components of the diaper 1, that is, the absorbent main body 10, the ventral band member 20, the dorsal band member 30, the separate dorsal band member 40, and the separate ventral band member 45 will be described.

  The absorbent main body 10 (see FIGS. 4 to 6) corresponds to the wearer's crotch (inseam) and is intended to absorb excrement such as urine. As shown in FIG. 4, the absorbent main body 10 has a rectangular shape in plan view, and is provided such that the longitudinal direction (long side direction) is along the vertical direction.

  The absorbent main body 10 includes an absorber 11, an absorber upper sheet member 12, an absorber lower sheet member 13, a top sheet member 14, and a back sheet member 15.

  The absorbent body 11 is a member (absorbent core) formed by laminating liquid absorbent materials, and can absorb excrement such as urine. The absorber 11 according to the present embodiment is a so-called SAP sheet. Here, the absorbent body 11 of the SAP sheet is substantially free of pulp (here, “substantially free of pulp” means that the weight of the pulp is more than 10% of the total weight of the absorbent body 11). This means an absorber 11 made of an absorbent polymer. Note that the SAP sheet according to the present embodiment does not contain any pulp.

  As shown in FIG. 5, the absorbent upper sheet member 12 and the absorbent lower sheet member 13 are liquid permeable covering the absorbent body 11 sandwiched from the upper side (skin side) and the lower side (non-skin side) in the thickness direction. It is a sheet (nonwoven fabric).

  As shown in FIG. 5, the top sheet member 14 is a sheet-like member that covers the absorber 11 sandwiched between the absorber upper sheet member 12 and the absorber lower sheet member 13 from the upper side (skin side). 11 is a liquid-permeable nonwoven fabric having a plane size larger than 11.

A plurality (18 in the present embodiment) are arranged (shown by broken lines). The ventral belt rubber 23 is interposed between the two nonwoven fabrics 21 and bonded and fixed to the two nonwoven fabrics 21. Further, each of the plurality of ventral side band rubbers 23 is provided from one end to the other end of the ventral side band member 20 in the lateral direction, and these ventral side band rubbers 23 are arranged in the vertical direction. It has become. As a result, the ventral belt member 20 is provided with lateral stretchability and imparts stretchability to the waist opening 1 a of the diaper 1.

  A sheet-like cover member 50 (nonwoven fabric) for enhancing the pulling strength is provided at the boundary between the ventral belt member 20 and the absorbent main body 10.

  The dorsal belt member 30 (see FIGS. 4 to 6) is a sheet-like member corresponding to the wearer's back and buttocks. As shown in FIG. 4, the back side band member 30 has a rectangular shape in plan view, and is provided such that the longitudinal direction (long side direction) is along the lateral direction. The back band member 30 is formed by overlapping and joining two nonwoven fabrics 31. In the present embodiment, as shown in FIGS. 4 and 5, an illustration sheet 32 on which an illustration (not shown) such as a floral pattern is formed is provided between the two nonwoven fabrics 31.

  The back side belt member 30 is overlapped and fixed to one end portion 10 a in the longitudinal direction of the absorbent main body 10. The portion of the back band member 30 that is overlapped with the absorbent main body 10 is provided on the central portion of the back band member 30 in the lateral direction and on the side closer to the center of the absorbent main body 10 of the back side band member 30 in the vertical direction. ing. In other words, the absorbent main body 10 is not overlapped on both ends of the back band member 30 in the lateral direction and on the side far from the center of the absorbent main body 10 of the back band member 30 in the vertical direction.

  Bonding and fixing are performed at both end portions 66a of the overlapping portion 66 in the lateral direction and the far end portion 66b on the side far from the center of the absorbent main body 10 in the longitudinal direction. However, joining and fixing are not performed at the near end portion 66c on the side close to the center of the absorbent main body 10 in the vertical direction and the center portion 66d. Therefore, a pocket-shaped one end insertion portion 80 having an opening at the near end portion 66c for inserting the one end portion Pa in the longitudinal direction of the pad P is formed in the gap between the back band member 30 and the absorbent main body 10. . As shown in FIG. 2, when the pad P is inserted into the diaper 1, one end portion Pa of the pad P is inserted into the one end insertion portion 80.

  Moreover, in this Embodiment, the back | dorsal band member 30 is piled up on the absorptive main body 10 so that the absorptive main body 10 may be covered from the skin side (inner side). That is, the back band member 30 is located on the skin side (inside) of the absorbent main body 10.

  Further, as shown in FIGS. 4 and 6, the back side band member 30 is an elastic member (specifically, thread rubber. For convenience, it is referred to as a back side band thread rubber 33). A plurality (16 in the present embodiment) are arranged (shown by broken lines). The back side band rubber 33 is interposed between the two nonwoven fabrics 31 and bonded and fixed to the two nonwoven fabrics 31. Further, each of the plurality of backside band rubbers 33 is provided from one end to the other end of the backside band member 30 in the lateral direction, and these backside band rubbers 33 are arranged in the longitudinal direction. It is in a state. As a result, the dorsal belt member 30 is provided with a lateral stretchability and imparts a stretchability to the waist opening 1 a of the diaper 1.

  A sheet-like cover member 50 (nonwoven fabric) for enhancing the pulling strength is provided at the boundary between the back band member 30 and the absorbent main body 10.

  The separate back side belt member 40 (see FIGS. 4 to 7) is a sheet-like member for maintaining the pad P inserted into the diaper 1 in an appropriate position. As shown in FIG. 4, the separate dorsal band member 40 is overlapped with the dorsal band member 30, and is located on the center side of the absorbent main body 10 with respect to the dorsal band member 30 in the vertical direction (in other words, the ventral band member 20. Side). Further, as shown in FIGS. 4 and 7, the separate back side band member 40 is provided so that the longitudinal direction thereof is substantially along the lateral direction as in the case of the back side band member 30 (strictly speaking, the separate back side band member 40 The central part 40a in the lateral direction of the side band member 40 is provided in a meandering state so as to be positioned closer to the central side of the absorbent main body 10 than the end part 40b (in other words, the abdominal side band member 20 side).

  The separate backside band member 40 is formed by overlapping and joining two nonwoven fabrics 41. In addition, in this Embodiment, while the length in the horizontal direction of the two nonwoven fabrics 41 is the same, as shown in FIG. 6, the length in the vertical direction differs. However, the length in the vertical direction may be the same.

  As described above, the separate backside band member 40 is overlapped with the backside band member 30, but as shown in FIG. 6, the backside band member 30 covers the backside band member 30 from the non-skin side (outside). It is piled up. Moreover, since the absorptive main body 10 is located in the non-skin side (outside) of the back | dorsal band member 30, in the overlapping part 70 of the separate back | dorsal band member 40 and the back | dorsal band member 30, both are absorptive main bodies. 10 (positioned in the central portion of the overlapping portion 70 in the lateral direction, referred to as the first overlapping region A1), and a portion overlapping both without the absorbent main body 10 ( Located at both ends in the lateral direction of the overlapping portion 70. This is called a second overlapping region A2. That is, in the first overlapping region A1, the separate back side band member 40 and the back side band member 30 overlap with the absorbent main body 10 sandwiched therebetween, and in the second overlapping region A2, the separate back side band member 40 and the dorsal belt member 30 are in contact with each other. The overlapping portion 70 is provided from one end to the other end in the lateral direction of the back side belt member 30 and the separate back side belt member 40, and is provided substantially along the horizontal direction.

  In addition, in the first overlap region A1, the separate backside band member 40 overlaps the backside band member 30 via the absorbent main body 10, so that when viewed from the absorbent main body 10, the separate backside band member 40 itself ( It will overlap with the absorbent main body 10 itself). Moreover, as shown in FIG. 4, the area | region (3rd side which adjoins 1st overlap area | region A1, and is located in the center side (in other words, the abdominal side belt member 20 side) of the absorptive main body 10 rather than 1st overlap area | region A1. The separate backside band member 40 overlaps the absorbent main body 10 also in the overlapping region A3). That is, as the overlapping portion 72 between the absorbent main body 10 and the separate backside band member 40, the first overlapping region A1 and the third overlapping region A3 exist. As is clear from FIG. 4, the length of the overlapping portion 72 in the vertical direction is longer than the length of the overlapping portion 70 in the vertical direction, and the length of the overlapping portion 72 in the horizontal direction is larger than the length of the overlapping portion 70 in the horizontal direction. Is also shorter. The overlapping portion 72 is provided from one end to the other end in the lateral direction of the absorbent main body 10 and is provided so as to be substantially along the lateral direction.

  Thus, the separate back side band member 40 is located on the non-skin side (outside) of the absorbent main body 10 and the back side band member 30. And as above-mentioned, since the back side belt member 30 is located in the skin side (inner side) of the absorptive main body 10, as shown in FIG. With the back side band member 40 positioned on the outside of the absorbent main body 10, the back side band member 30 and the separate back side band member 40 sandwich the absorbent main body 10. In the present embodiment, as described above, the separate back side band member 40 and the back side band member 30 sandwich the absorbent main body 10 in the first overlapping region A1. And in the said 1st overlap area | region A1, the separate back | dorsal band member 40 will cover the one end insertion part 80 located in the overlap part 66 mentioned above from the non-skin side (outside).

  Further, in the overlapping portion 72 (the first overlapping region A1 and the third overlapping region A3), the separate back side band member 40 and the absorbent main body 10 are joined. In addition, in the second overlapping region A2, the separate back side band member 40 and the back side band member 30 are joined.

  In addition, it has already been described that both edges 30a in the lateral direction of the back band member 30 are joined to both edges 20a in the lateral direction of the abdominal band member 20, but both sides of the separate back band member 40 in the lateral direction have been described. The edge portion 42 is also joined to both edge portions 20a in the lateral direction of the ventral side belt member 20. Further, the both edge portions 42 are also joined to both edge portions 47 in the lateral direction of a separate ventral side belt member 45 described later.

  Further, as shown in FIGS. 4, 6, and 7, the separate back side band member 40 is an elastic member (specifically, rubber thread. Specifically, a separate back side band thread for convenience. It is called rubber 43. In the figure, a plurality (in the present embodiment, five) are arranged. This separate backside band thread rubber 43 is interposed between the two nonwoven fabrics 41 and joined and fixed to the two nonwoven fabrics 41. Further, as shown in FIG. 4, each of the plurality of separate backside band thread rubbers 43 is provided from one end to the other end of the separate backside band member 40 in the lateral direction. Crossed. Furthermore, these separate backside band thread rubbers 43 are arranged in the longitudinal direction. As a result, the separate dorsal belt member 40 is provided with a substantially horizontal stretchability.

  Further, the stress of the separate back-side band rubber 43 (in other words, the tension of the separate back-side band rubber 43. That is, the stress of the separate back-side band member 40 in the expansion and contraction direction of the separate back-side band rubber 43) is The central portion 40a is smaller than the end portion 40b in the lateral direction of the separate back side belt member 40 (the reason for this will be described later). In the present embodiment, when attaching the separate backside belt rubber 43 to the separate backside belt member 40, the separate backside belt rubber 43 is attached in a loosened state at the central portion 40a rather than the end portion 40b. (The end portion 40b is attached by extending the separate back-side belt rubber 43 more). This realizes a stress difference between the central portion 40a and the end portion 40b.

  Further, in the present embodiment, as described above, the five separate back-side belt rubbers 43 are arranged in the vertical direction, but the five separate back-side belt rubbers 43 are arranged at an equal pitch. Do not mean. That is, four of these separate back-side band thread rubbers 43 are end portions closer to the center of the absorbent main body 10 among the both ends in the longitudinal direction of the separate back-side band member 40 (for convenience, the near-end 1 is located at the far end (referred to as the far end 40d for convenience). Further, the separate back-side band rubber 43 (far-end thread rubber 43b) of the far-end portion 40d is positioned (intersects) with the overlapping portion 70 of the back-side band member 30 and the separate back-side band member 40. On the other hand, the separate back-side band thread rubber 43 (near-end thread rubber 43a) of the near end portion 40c is not located in the overlapping portion 70. That is, the separate back-side belt rubber 43 is provided at positions corresponding to both the overlapping portion 70 and the non-overlapping portion of the separate back-side belt member 40.

  Further, the four near-end thread rubbers 43 a intersect with the absorbent main body thread rubber 17 provided on the side flap 16. And the intersection (a plurality exists. For example, the intersection C1 in FIG. 4) of both the rubber threads is on the joint part which joins both members in the overlapping part 72 of the absorptive main body 10 and the separate body belt member 40. positioned. In other words, the absorptive main body 10 and the separate backside band member 40 are joined at the intersection C1.

  The separate ventral belt member 45 (see FIGS. 4 to 6 and 8) is a sheet-like member for maintaining the pad P inserted in the diaper 1 in an appropriate position. As shown in FIG. 4, the separate dorsal belt member 40 is overlapped with the ventral belt member 20 in the longitudinal direction in the longitudinal direction with respect to the center side of the absorbent main body 10 (in other words, the dorsal belt member 30. Side). Further, as shown in FIG. 4, the separate abdominal band member 45 is provided so that the longitudinal direction thereof is along the horizontal direction, like the abdominal band member 20. The length of the separate abdominal band member 45 in the vertical direction is smaller than the length of the separate back side band member 40 in the vertical direction.

In the present embodiment, the two nonwoven fabrics 46 have the same length in the horizontal direction, but have different lengths in the vertical direction as shown in FIG. However, the length in the vertical direction may be the same.

  As described above, the separate abdominal band member 45 is superimposed on the abdominal band member 20, but as shown in FIG. 6, the abdominal band member 20 is covered with the abdominal band member 20 from the non-skin side (outside). It is piled up. Moreover, since the absorptive main body 10 is located in the non-skin side (outside) of the abdominal side belt member 20, both the absorptive main body 10 are in the overlap part 74 of the separate abdominal side belt member 45 and the abdominal side belt member 20. And a portion overlapping with each other without the absorbent main body 10 (overlapping) (the overlapping portion 74 is located in the central portion in the lateral direction of the overlapping portion 74 and called the fourth overlapping region A4). Located at both ends of the portion 74 in the lateral direction (referred to as a fifth overlapping region A5). That is, in the fourth overlap region A4, the separate ventral belt member 45 and the ventral belt member 20 overlap with the absorbent main body 10 sandwiched therebetween, and in the fifth overlap region A5, the separate ventral belt member 45. And the ventral belt member 20 are in contact with each other. The overlapping portion 74 is provided from one end to the other end in the lateral direction of the ventral belt member 20 and the separate ventral belt member 45, and is provided along the lateral direction.

  Further, in the fourth overlap region A4, the separate ventral belt member 45 overlaps the ventral belt member 20 via the absorbent main body 10, so that when viewed from the absorbent main body 10, the separate ventral belt member 45 itself ( It will overlap with the absorbent main body 10 itself). Further, as shown in FIG. 4, a region (sixth region) adjacent to the fourth overlapping region A4 and located closer to the center side of the absorbent main body 10 (in other words, the back side belt member 30 side) than the fourth overlapping region A4. The separate ventral belt member 45 overlaps the absorbent main body 10 also in the overlapping region A6). That is, the fourth overlapping region A4 and the sixth overlapping region A6 exist as the overlapping portion 76 between the absorbent main body 10 and the separate ventral belt member 45. As apparent from FIG. 4, the length of the overlapping portion 76 in the vertical direction is longer than the length of the overlapping portion 74 in the vertical direction, and the length of the overlapping portion 76 in the horizontal direction is larger than the length of the overlapping portion 74 in the horizontal direction. Is also shorter. The overlapping portion 76 is provided from one end to the other end in the lateral direction of the absorbent main body 10 and is provided along the lateral direction.

  In this way, the separate ventral belt member 45 is located on the non-skin side (outside) of the absorbent main body 10 and the ventral belt member 20. And as above-mentioned, since the abdominal side belt member 20 is located in the skin side (inner side) of the absorptive main body 10, as shown in FIG. The abdominal band member 20 and the separate abdominal band member 45 sandwich the absorbent main body 10 in a state where the ventral band member 45 is located outside the absorbent main body 10. In the present embodiment, as described above, the separate abdominal band member 45 and the abdominal band member 20 sandwich the absorbent main body 10 in the fourth overlapping region A4. And in the said 4th overlap area | region A4, the separate ventral | abdominal band member 45 will cover the other end insertion part 82 located in the overlap part 64 mentioned above from the non-skin side (outside).

  Further, in the overlapping portion 76 (fourth overlapping region A4 and sixth overlapping region A6), the separate ventral belt member 45 and the absorbent main body 10 are joined. In the fifth overlapping region A5, the separate ventral belt member 45 and the ventral belt member 20 are joined.

  Further, as shown in FIGS. 4, 6, and 8, the separate abdominal belt member 45 is an elastic member that stretches in the horizontal direction (specifically, thread rubber. This is called 48. In the drawing, a plurality (in the present embodiment, three) are arranged. This separate ventral band thread rubber 48 is interposed between the two nonwoven fabrics 41 and joined and fixed to the two nonwoven fabrics 41. Further, as shown in FIG. 4, each of the plurality of separate ventral side band rubbers 48 is provided from one end to the other end in the lateral direction of the separate ventral side band member 45, and Crossed. Further, these separate ventral side band rubbers 48 are arranged in the longitudinal direction. As a result, the separate ventral belt member 45 is provided with lateral stretchability. Further, the stress of the separate abdominal band rubber 48 (in other words, the tension of the separate abdominal band rubber 48. That is, the stress of the separate abdominal band member 45 in the expansion and contraction direction of the separate abdominal band rubber 48) The separate ventral belt member 45 is smaller in the central portion 45a than the end portion 45b in the lateral direction.

  The three separate abdominal side band rubbers 48 are located at the end of the separate abdominal side band member 45 that is closer to the center of the absorbent main body 10 in the longitudinal direction. The separate ventral belt rubber 48 is not located in the overlapping portion 74 between the ventral belt member 20 and the separate ventral belt member 45. Further, the separate ventral belt rubber 48 intersects the absorbent main body rubber 17 provided on the side flap 16. And the intersection (a plurality exists. For example, the intersection C2 in FIG. 4) of both thread rubbers is on the joint part which joins both members in the overlap part 76 of the absorptive main body 10 and the separate ventral | abdominal belt member 45. positioned. In other words, the absorptive main body 10 and the separate ventral belt member 45 are joined at the intersection C2.

=== Effectiveness of Diaper 1 According to this Embodiment ===
As described above, the diaper 1 according to the present embodiment has a longitudinal direction and a transverse direction that intersects the longitudinal direction, and absorbs excrement, and the longitudinal direction of the absorbent body 10. A dorsal band member 30 fixed to one end 10a in the direction and an abdominal band member 20 fixed to the other end 10b in the longitudinal direction of the absorbent main body 10, and the dorsal band member 30 in the lateral direction The diaper 1 was formed by joining both edge portions 30a and both edge portions 20a of the ventral belt member 20 in the lateral direction. In addition, it has a thread rubber, and has a separate back side belt member 40 and a separate back side belt member 45 different from the absorbent main body 10, the back side belt member 30, and the abdominal side belt member 20, One back side member (in this embodiment, the back side belt member 30) of the back side belt members 30 is disposed inside the absorbent main body 10, and the other back side member (in this embodiment, a separate back). In the state where the side band member 40) is located outside the absorbent main body 10, the back side band member 30 and the separate back side band member 40 sandwich the absorbent main body 10, and the back side band member 30 and One end insertion portion 80 for inserting one end portion Pa of the pad P is formed in the gap of the absorbent main body 10, and one of the separate ventral side belt member 45 and the ventral side belt member 20 (this embodiment). The ventral belt member 20) is on the inside of the absorbent main body 10 and the other With the ventral member (in this embodiment, a separate ventral band member 45) positioned on the outside of the absorbent main body 10, the ventral band member 20 and the separate ventral band member 45 are absorbent. The other end insertion portion 82 for inserting the other end portion Pb of the pad P is formed in the gap between the ventral belt member 20 and the absorbent main body 10 with the main body 10 interposed therebetween. Therefore, the pad P inserted into the diaper 1 can be maintained at an appropriate position.

  Conventionally, an absorbent main body that absorbs excrement, a back band member fixed to one end portion in the longitudinal direction of the absorbent main body, and a ventral band member fixed to the other end portion in the vertical direction of the absorbent main body, In addition, a so-called three-piece type diaper formed by joining both edges in the lateral direction of the back band member and both edges in the lateral direction of the ventral band member is widely used.

  And when using this diaper, a pad may be inserted and used for the said diaper. One end insertion portion for inserting one end of the pad is formed in the gap between the back band member and the absorbent main body, and the other end of the pad is inserted in the gap between the ventral band member and the absorbent main body. Therefore, when the pad is inserted into the absorbent article, one end of the pad is inserted into the one end insertion portion, and the other end is inserted into the other end insertion portion.

  However, conventionally, the pad is not properly pressed in the one end insertion portion and the other end insertion portion, and there is a problem that the pad cannot be maintained at an appropriate position (the pad becomes easy to move). As a result, there is a problem that the pad is displaced and the excrement leaks.

  On the other hand, in the present embodiment, a separate back side band member 40 and a separate abdominal side band member 45 provided with rubber thread are separately prepared, and the back side band member 30 and the separate back side band member 40 are absorbent. The main body 10 is sandwiched, and the abdominal band member 20 and the separate abdominal band member 45 sandwich the absorbent main body 10. Therefore, in a state where the gap between the back band member 30 and the absorbent main body 10, that is, the one end Pa of the pad P inserted into the one end insertion portion 80 is sandwiched between the separate back side band member 40 and the back side band member 30. It is appropriately pressed down by both members. Further, the gap between the ventral band member 20 and the absorbent main body 10, that is, the other end portion Pb of the pad P inserted into the other end insertion portion 82 is sandwiched between the separate ventral band member 45 and the ventral band member 20. It can be properly pressed by both members. Therefore, it becomes possible to maintain the pad P at an appropriate position (the pad P becomes difficult to move), and it is possible to suppress the problem that the pad P is displaced and the excrement leaks.

  In the present embodiment, the separate back side band member 40 and the absorbent main body 10 are joined, and the separate ventral side band member 45 and the absorbent main body 10 are joined. Therefore, the separate back side band member 40 and the separate abdominal side band member 45 do not float from the absorbent main body 10, and thus the pad P can be more appropriately pressed through the absorbent main body 10. Therefore, the pad P can be more reliably maintained at an appropriate position.

In the central part, the stress of the rubber thread is small. Therefore, the occurrence of an event that makes it difficult to insert the pad P into the one end insertion portion 80 (the other end insertion portion 82) due to the absorptive main body 10 positioned at a position corresponding to the center portion contracting in the lateral direction due to the stress. It is possible to maintain the pad P in an appropriate position while considering suppression.

  Further, in the present embodiment, at least one member of the absorbent main body thread rubber 17 provided on the side flap 16, the separate back side belt member 40 and the separate back side belt member 45 (in this embodiment) Is crossed with the thread rubber (separate backside belt rubber 43, separate abdominal band rubber 48) provided on both members, and is provided on both members of the absorbent main body thread rubber 17. The intersection C1 (intersection C2) of the thread rubber (separate backside belt rubber 43, separate abdominal band rubber 48) is the absorbent main body 10 and the one member (separate backside belt member 40, separate ventral sideband). The overlapping portion 72 (overlapping portion 76) with the member 45) is located on the joint for joining both members. Therefore, the thread rubbers that intersect each other can be directly linked to each other (by the interaction of both thread rubbers), and the pad P can be pressed more appropriately. Therefore, it is possible to more reliably maintain the pad P at an appropriate position.

  Moreover, in the said embodiment, the rubber thread (separate body) provided in at least one member (in this embodiment, both members) of the separate back side band member 40 and the separate abdominal side band member 45 The dorsal side belt rubber 43 and the separate ventral side belt rubber 48) intersect with the absorbent main body 10. Therefore, it is possible to hold the absorbent main body 10 from one end to the other end in the lateral direction by the elastic force of the rubber thread, and the elastic main body 10 is positioned in the gap between the absorbent main body 10 and the back band member 30 (abdominal band member 20). The pad P to be pressed can be pressed more appropriately. Therefore, it is possible to more reliably maintain the pad P at an appropriate position.
