And both side walls extending between the first and second folding lines connected to the front and rear walls, and the front and rear walls facing each other are inclined toward the second sheet from the opening toward the second sheet. , Facing each other of the mount Both side walls of the liquid-absorbing core are inclined toward the end of the second sheet from the opening, and the peripheral edge of the opening of the first sheet conforms to the front and rear walls and both side walls of the mount. The front wall of the mount is located between the first folding lines and gradually separated from the first folding line from the opening toward the second sheet. A central portion that is bent by a pair of third folding curves, extends between the third folding curves and is recessed rearward in the longitudinal direction of the peripheral edge of the opening, and extends between the first and third folding curves. And the rear wall of the mount is located between the second folding lines and gradually extends from the second folding line from the opening toward the second sheet. It is bent by a pair of spaced apart fourth fold curves and extends between the fourth fold curves so as to open the opening. The central portion of the peripheral portion that is recessed forward in the longitudinal direction and the both side portions that extend between the second and fourth folding lines and face the both side walls are partitioned, and the central portion of the rear wall is A recessed portion is formed by cutting out the mount from the outer peripheral edge of the mount extending toward the second sheet toward the inner peripheral edge of the mount extending toward the opening. It extends to the recessed part of the wall.
According to another aspect of the present invention, the pants further include a belt-like pad fixing sheet that is disposed on an inner side and extends between the front and rear waist areas, and the pad fixing sheet includes the waist area of the front and rear waist areas. An insertion opening having a fixed both end portion fixed to a peripheral edge portion and a free intermediate portion extending between the both fixed end portions and capable of inserting a rear region of the pad is formed at a lateral center of the free intermediate portion. And the pad has a connecting sheet positioned on the outer surface of the first sheet with an opening connected to the opening of the first sheet, and the front region and the intermediate region of the pad are fixed to the pad. Located on the outer surface of the sheet, the rear region is inserted into the insertion port of the fixed sheet and interposed between the pants and the fixed sheet, and the connecting sheet is located at the opening peripheral edge of the first sheet A fixed inner peripheral edge, and A free front portion extending from the front area of the pad in the vertical direction and detachably attached to the fixed sheet via a fixing means, and fixed to the pad fixing sheet located in the rear area of the pad A free rear portion that is detachably attached via a means, and the free rear portion is formed with a recessed portion in which the connecting sheet is cut out from an outer peripheral edge of the connecting sheet toward the fixed inner peripheral edge. And the second space extends to the recessed portion of the connecting sheet.

The present invention has the following embodiments.
(1) A spacer having elastic elasticity in a lateral direction is disposed in the first space and attached to the both side walls so as to be shrinkable, and the both side walls are disposed in the lateral direction of the pad by the shrinkage force of the spacers. It is attracted towards.
(2) Both side walls of the mount are tapered from the rear wall of the mount toward the front wall, and the area of the rear wall is larger than that of the front wall.
(3) The fastening means is a hook member attached to the inner surface of the connecting sheet or a pressure-sensitive adhesive applied to the inner surface of the connecting sheet.
(4) The area of the rear area of the pad is larger than that of the front area and the intermediate area of the pad, and the rear area has a bag shape that spreads laterally toward the rear in the vertical direction of the pad. .

  According to the excrement disposal pad according to the present invention, the second space that is located above the first space and extends in the vertical direction is formed between the horizontal center portion of the first sheet and the core. Even if one sheet and the core come into contact with each other and the first space is blocked, the excrement passes from the intermediate region to the front and rear region through the second space, and the excrement can be efficiently absorbed and held throughout the entire core. .

  A pad in which a mount is fixed to the opening peripheral edge of the first sheet and the mount is bent through the first and second folding lines, the opening peripheral edge conforms to the front and rear walls and both side walls of the mount. Since the opening peripheral part forms a barrier against excrement, the excrement accommodated in the first space does not get over the opening peripheral part, and the excrement opening Leakage from can be prevented. Since the pad has a higher rigidity than the first and second sheets, the pad has a three-dimensional shape of the opening peripheral portion that protrudes upward from the core even if some pressure is applied in the thickness direction of the pad. It is maintained by the mount, and the opening periphery is not crushed, and the opening periphery does not lose its function as a barrier against excrement.

  In a pad where the front wall of the mount is bent at the first and third folding curves and the rear wall of the mount is bent at the second and fourth folding curves, the front wall extends between the first and third folding curves Both side portions of the rear wall support the pressure applied in the thickness direction of the pad together with the both side walls, and both side portions of the rear wall extending between the second and fourth folding lines support the pressure applied in the thickness direction of the pad together with the both side walls. The buckling strength of the mount with respect to the pressure applied in the thickness direction of the pad is improved, the mount is hard to be crushed, and the three-dimensional form of the opening peripheral edge protruding upward from the core is reliably maintained by the mount.

  A recessed portion in which the mount is cut out is formed at the center of the rear wall of the mount, and the pad in which the second space extends to the recessed portion of the rear wall is projected upward of the core in the recessed portion of the rear wall. The shape of the 1st sheet | seat which becomes can be maintained, and since the back wall of the mount does not block the 2nd space, excretion passes the 2nd space to the back area of a pad reliably.

  Pads with elastically stretchable spacers attached to both side walls so that they can be shrunk in the lateral direction are drawn by the spacers so that the two side walls of the mount are drawn inwardly in the lateral direction of the pads. It is reliably maintained, and the three-dimensional form of the peripheral edge of the opening that protrudes upward from the core is reliably maintained by the mount and the spacer. Even if this pad is subjected to a large pressure in the thickness direction, the periphery of the opening is crushed and the mount becomes flat, when the pressure is released, the mount is immediately restored to a three-dimensional form by the contraction force of the spacer, As a result, the peripheral edge of the opening is restored to a three-dimensional shape that protrudes upward from the core.

  When the side walls of the mount are tapered from the back wall of the mount toward the front wall, and the area of the back wall of the mount is larger than that of the front wall of the mount, Since both the side walls fit in the crotch portion of the wearer, it is possible to prevent the peripheral edge of the opening in the crotch portion of the wearer from being bulky.

  The connecting sheet is arranged on the outer surface of the first sheet, and the pad attached to the pants by fixing the free front portion of the connecting sheet to the outer surface of the pad fixing sheet arranged on the inside of the pants has the pad attached to the pants. Sometimes, the front area and the middle area of the pad are positioned on the outer surface of the fixed sheet and fixed to the fixed sheet, so that the movement of the pants can be directly transmitted to the pad compared to the case where the pad is attached to the pant itself. Even if the pants are moved by the wearer's movement, the pad does not move following it. Even if the pants are deviated from the wearing position, the pads do not deviate and the pad can be kept in contact with the wearer's skin. Since the rear area of this pad is located between the pants and the pad fixing sheet, even if the wearer's body pressure is applied to the pad, the rear area of the pad is not easily crushed and excreted in the rear area of the pad. Objects do not leak from the opening. Moreover, since the pad containing the excrement can be removed from the pants and discarded, and only the pad can be replaced, the pants can be used repeatedly.

  A pad having a free rear part that can be attached to and detached from the pad fixing sheet is connected to the outer surface of the fixing sheet together with the free front part of the connecting sheet when the pad is attached to the pants. Compared with the case where only the front part is fixed to the fixed sheet, the pad can be securely fixed to the fixed sheet, and the displacement movement of the pad inside the pants can be prevented.

  A recessed portion in which the connecting sheet is cut out is formed in the free rear portion of the connecting sheet, and the pad in which the second space extends to the recessed portion of the connecting sheet is convex upward of the core in the recessed portion of the connecting sheet. Since the form of the first sheet can be maintained and the second space is not crushed by the free rear portion of the connecting sheet, the excrement reliably moves to the rear area of the pad through the second space.

  The pad's rear area is larger than that of the front area and the middle area, and the rear area of the pad has a bag shape that spreads laterally toward the rear of the pad. Even if a large amount of excrement is excreted during use of the pad, all of the excrement can be accommodated in the first space of the rear wall.

  FIG. 7 is a perspective view of the pad 20 </ b> A of FIG. 1 shown in the mounted state, and the pad 20 </ b> A is attached to the inside of the diaper cover 59. In FIG. 7, the horizontal direction is indicated by an arrow L, the vertical direction is indicated by an arrow M, and the thickness direction is indicated by an arrow N. The cover 59 has both end portions 60 extending in the lateral direction and both side portions 61 extending in the vertical direction. The front waist region 62 and the rear waist region 64 are vertically disposed between the waist regions 62 and 64. And a crotch region 63 located at the bottom. In the crotch region 63, both side portions 61 are curved inward in the lateral direction of the cover 59. The cover 59 has an hourglass shape in plan view.

  The cover 59 is formed of a composite sheet obtained by laminating a hydrophobic fiber nonwoven fabric 65 located on the skin contact side and a ventilation impermeable plastic film 66 located on the skin non-contact side. A belt-like elastic member 67 for waistline extending in the lateral direction is attached to both end portions 60 so as to be contractible. A plurality of leg-around elastic members 68 extending in the vertical direction are attached to the side portions 61 so as to be shrinkable. These elastic members 67 and 68 are interposed between the non-woven fabric 65 and the film 66, and are fixed to the non-woven fabric 65 and the film 66 in a state of being stretched at a predetermined magnification. A pair of tape fasteners 69 extending in the lateral direction are attached to both side portions 61 of the rear waist region 64. The free part of the tape fastener 69 is coated with an adhesive that is covered and protected by a release paper (not shown). A rectangular target tape 70 is fixed to the outer surface of the film 66 in the front waistline region 62 so that the free portion of the tape fastener 69 is detachably fastened.

  The procedure for mounting the pad 20A is as follows. The release paper 58 is peeled off to expose the adhesive 30, and the outer surface of the second sheet 22 is fixed to the inside (nonwoven fabric 65) of the cover 59 via the adhesive 30, and the pad 20 </ b> A is attached to the cover 59. When the pad 20A is attached to the cover 59, the front region 43 of the pad 20A is located in the front waistline region 62 and the crotch region 63, the intermediate region 44 is located in the crotch region 63, and the rear region 45 is inseam Located in a region 63 and a rear waistline region 64. The opening 31 formed in the first sheet 21 is located in the crotch region 63 of the cover 59. After the pad 20A is attached to the cover 59, the crotch region 63 of the cover 59 is positioned at the crotch portion of the wearer, and both side portions 61 of the back waist region 64 are moved to the abdomen side of the wearer, so that the back waist region Both side portions 61 of 64 are overlapped on the outside of both side portions 61 of the front waistline region 62. Next, the free part of the tape fastener 69 is fixed to the outer surface of the target tape 70 via the adhesive, and the front waistline region 62 and the back waistline region 64 are connected. The cover 59 to which the front and rear waist areas 62 and 64 are connected is formed with a waist opening and a pair of leg openings (not shown). Excretion excreted during the mounting of the pad 20 </ b> A passes through the opening 31 and is accommodated in the first space 32, and is absorbed and held in the core 23.

  In the pad 20 </ b> A, the lateral center portion 33 of the first sheet 21 protrudes upward from the core 23 along the longitudinal center line M <b> 1, and a first space is formed between the lateral center portion 33 of the first sheet 21 and the core 23. Since the second space 34 that is located above the portion 32 and extends in the vertical direction is formed, even if the first sheet 21 and the core 23 come into contact with each other and the first space 32 is blocked, the excrement is in the second space. 34, the intermediate region 25 of the pad 20A moves to the front and rear regions 24, 26, and the excreta can be efficiently absorbed and held throughout the core 23. In the pad 20 </ b> A, since the opening peripheral portion 35 that protrudes upward from the second sheet 22 forms a barrier against excrement, the excrement does not go over the opening peripheral portion 35, and excretion accommodated in the first space 32. An object does not leak from the opening 31 to the outside of the pad 20A. The pad 20A has a rigidity higher than that of the first and second sheets 21 and 22 because the mount 36 has higher rigidity than the first and second sheets 21 and 22, even if pressure is applied in the thickness direction of the pad 20A, A form is hold | maintained, the opening peripheral part 35 does not collapse easily, and the opening peripheral part 35 does not lose the function as a barrier with respect to excrement.

  In the pad 20 </ b> A, both side portions 47 of the front wall 43 extending between the first and third folding lines 39 and 41 support the pressure applied to the thickness direction of the pad 20 </ b> A together with the side walls 44. , 42 and both side portions 49 of the rear wall 45 support the pressure applied in the thickness direction of the pad 20A together with the side walls 44, so that the buckling strength of the mount 36 against the pressure applied in the thickness direction of the pad 20A is improved. The mount 36 is not easily crushed, and the three-dimensional form of the opening peripheral edge 35 is reliably maintained by the mount 36. Further, since both side walls 44 of the mount 36 are attracted inward in the lateral direction of the pad 20A by the contraction force of the spacer 51, the three-dimensional form of the mount 36 is reliably maintained by the spacer 51, and the upper side of the core 23 is The three-dimensional form of the opening peripheral edge 35 that is convexly convex is reliably maintained by the mount 36 and the spacer 51. Even if the pad 20A is subjected to a large pressure in the thickness direction and the peripheral edge 35 of the opening is crushed and the mount 36 becomes flat, the mount 36 immediately becomes a three-dimensional form by the contraction force of the spacer 51 when the pressure is released. Thus, the opening peripheral portion 35 is restored to a three-dimensional form that protrudes upward from the core 23.

  The pad 20 </ b> A has a recessed portion 50 formed in the central portion 48 of the rear wall 45 of the mount 36, and the second space 34 extends to the recessed portion 50 of the rear wall 45. The form of the first sheet 21 that protrudes upward can be maintained, the rear wall 45 of the mount 36 does not block the second space 34, and excrement passes through the second space 34 and the rear area of the pad 20 </ b> A. Transition to 45 without fail. The pad 20A has a bag-like shape in which the rear area 45 spreads in the lateral direction toward the rear in the vertical direction of the pad 20A. Therefore, the volume of excreta in the first space 32 in the rear area 45 is large, and the pad 20A is being used. Even if a large amount of excrement is excreted, all of the excrement can be accommodated in the first space 32 of the rear area 45. In the pad 20A, both side walls 44 of the mount 36 are tapered from the rear wall 45 toward the front wall 43, and the area of the front wall 43 is smaller than that of the rear wall 45. Therefore, when the pad 20A is mounted, the pad 20A is mounted. The front wall 43 and the both side walls 44 of 36 will fit in a wearer's crotch part, and the opening peripheral part 35 will not be bulky in a crotch part.

The rigidity value of the mount 36 is in the range of 2 to 40 mN · m. When the stiffness value of the mount 36 is less than 2 mN · m, the mount 36 is easily crushed when pressure is applied in the thickness direction of the pad 20 </ b> A, and the shape of the opening peripheral edge 35 that protrudes upward from the core 23 is maintained. I can't. When the stiffness value of the mount 36 exceeds 40 mN · m, the opening peripheral edge portion 35 that comes into contact with the wearer's skin during wearing of the pad 20 </ b> A gives an unpleasant stimulus to the wearer. The rigidity value of the mount 36 was measured according to the Taber method (JIS P 8125). The measurement method is as follows.
(1) The same mount 36 used for the pad 20A was cut to prepare a measurement sample having a vertical dimension of 50 mm and a horizontal dimension of 25 mm. For the measurement of the rigidity value, a Taber Stiffness Tester manufactured by Yasuda Seiki Seisakusho Co., Ltd. was used, and the rigidity values in the vertical and horizontal directions of the sample were measured.
(2) Next, the measurement procedure will be described. (a) The thickness (A) of the sample is measured. (b) Insert the sample so that it touches the center of the chuck (lower side) of the testing machine. (c) The sum of the left and right gaps between the support roller and the sample is adjusted to (A) × 0.80 (mm). (d) Put the auxiliary weight 1/2 on top. (e) Rotate the sample in both the left and right directions, stop at the point where the 15-degree support score coincides with the center score of the pendulum, and read the scale on the testing machine. The numerical value on the left side of the scale is (B), and the numerical value on the right side of the scale is (C).
(3) The stiffness value of the sample was calculated by the formula: stiffness value (N · cm) = ((B) + (C)) / 2 × (auxiliary weight coefficient) /1000×9.807. The calculated rigidity value of the sample in the vertical and horizontal directions is 2 to 40 mN · m, and the rigidity value of the sample is set as the rigidity value of the mount 36.

In the pad 20A, the lateral extensional stress of the spacer 51 is in the range of 0.01 to 1.5N. If the elongation stress of the spacer 51 is less than 0.01 N, the side walls 44 of the mount 36 cannot be sufficiently pulled in the lateral direction of the pad 20A due to the contraction force of the spacer 51. If the extension stress of the spacer 51 exceeds 1.5 N, the side walls 44 of the mount 36 that are attracted in the lateral direction by the contraction force of the spacer 51 may come into contact with each other, and the opening 31 may close its mouth. The elongation stress of the spacer 51 was measured by the following method.
(1) The spacer 51 removed from the pad 20A was cut to prepare a measurement sample having a vertical dimension of 100 mm × a horizontal dimension of 70 mm. A tensile tester manufactured by Shimadzu Corporation was used for the measurement of the elongation stress.
(2) Next, the measurement procedure will be described. Both ends of the sample in the lateral direction are clamped by a chuck of a tensile tester (sample clamping dimension of the chuck: about 10 mm, dimension between the chucks of the sample: about 50 mm), and the sample is pulled laterally at a speed of 100 mm / min. After extending to 300%, the extended state is released. Again, the sample was pulled laterally through the testing machine at a speed of 100 mm / min, the sample was stretched to 200%, and the force applied to the testing machine at that time was measured. Here, elongating the sample to 200% means, for example, that when the inter-chuck dimension of the sample is 50 mm, the sample is extended to about 100 mm, which is a value obtained by multiplying 2.0 by 50 mm. The elongation stress of the sample was 0.01 to 1.5 N, and the elongation stress of the sample was taken as the elongation stress of the spacer 51.

The pad 20B is different from that shown in FIG. 1 in that a connecting sheet 71 extending in the vertical direction is attached to the outer surface of the first sheet 21, and the pad 20B is attached to the inside of the pants 80 described later via the connecting sheet 71. is there. Since the other configuration of the pad 20B is the same as that of the pad 20B in FIG. 1, the same reference numerals as those in FIG.

  Urethane foam is used for the connecting sheet 71. The connecting sheet 71 is formed with an opening 72 that extends in the longitudinal direction passing through the connecting sheet 71. The opening 72 has the same shape and size as the opening 31 and is connected to the opening 31. The connecting sheet 71 surrounds the opening 72 and is fixed to the outer peripheral surface of the opening peripheral edge 35, a fixed inner peripheral edge 73, a free front part 74 extending longitudinally forward from the peripheral edge 73, and a vertical direction from the peripheral edge 73. And a free rear portion 75 extending rearward. The free front portion 74 extends longitudinally forward from the front region 43 of the pad 20B. The free rear portion 75 is located on the rear region 45 of the pad 20B. The free front portion 74 and the free rear portion 75 are not fixed to the first sheet 21. On the inner surface of the free front portion 74, a circular hook member 76 (fixing means) arranged in a laterally spaced manner is fixed. On the inner surface of the free rear portion 75, a circular hook member 77 (fixing means) arranged in a laterally spaced manner is fixed. Note that the inner surfaces of the free front and rear portions 74 and 75 are surfaces facing the core 23. The free rear portion 75 is formed with a recessed portion 79 in which the connecting sheet 71 is cut out from the outer peripheral edge 78 of the connecting sheet 71 toward the fixed inner peripheral edge 73. The recessed portion 79 extends in the vertical direction along the vertical center line M1. A second space 34 extends in the recessed portion 79.

  FIGS. 13 and 14 are a partially broken perspective view of the pants 80 and a partially broken perspective view of the pants 80 shown with the pad 20B attached. FIGS. 15 and 16 are cross-sectional views taken along line 15-15 in FIG. It is a figure and the enlarged view of FIG. 13 and 14, the horizontal direction is indicated by an arrow L, and the vertical direction is indicated by an arrow M. In addition, the outer surface of the fixed sheet 92 refers to a surface facing the wearer. The pants 80 are made of a hydrophobic fiber nonwoven fabric. The pants 80 have a front waistline region 81 and a back waistline region 83 that are opposed to each other, and a crotch region 82 that is positioned between the waistline regions 81, 83. In the pants 80, the side portions 84 of the front and rear waist regions 81 and 83 overlap each other, and the side portions 84 of the waist regions 81 and 83 are fixed via a large number of heat-sealed portions 85 arranged intermittently. The pant 80 is formed with a waist opening 86 and a pair of leg openings 87.

  A plurality of waistline elastic members 89 extending in a ring shape are attached to the waist periphery 88 of the pants 80 surrounding the waist opening 86 so as to be contractible. A plurality of leg-around elastic members 91 extending in a ring shape are attached to the leg periphery 90 of the pants 80 surrounding the leg opening 87 so as to be contractible. The elastic members 89 and 91 are fixed to the pants 80 via an adhesive (not shown) in a state where the elastic members 89 and 91 are expanded to a predetermined magnification. On the inner side of the pants 80, a belt-like pad fixing sheet 92 that is positioned between the front and rear waist regions 81 and 83 and extends in the vertical direction is attached.

  For the fixing sheet 92, a hydrophobic fiber nonwoven fabric having elastic stretchability is used. The fixed sheet 92 forms an arc downward from the front and rear waist regions 81 and 83 of the pants 80 toward the crotch region 82. The fixed sheet 92 has fixed both end portions 93 fixed to the waist periphery 88 of the front and rear waist regions 81 and 83, and a free intermediate portion 94 extending between the fixed both end portions 93. The free intermediate portion 94 is not fixed to the pants 80 and is spaced upward from the crotch region 82 of the pants 80. A slit 95 (insertion opening) is formed in the middle of the free intermediate portion 94 in the lateral direction by cutting the fixed sheet 92 while slightly leaving both lateral sides. The slit 95 is formed at the center in the longitudinal direction of the crotch region 82 of the pants 80 and extends in the lateral direction.

  The procedure for attaching the pad 20B to the pants 80 is as follows. The front region 24 and the intermediate region 25 of the pad 20B are disposed on the outer surface of the fixed sheet 92, and the rear region 26 of the pad 20B is inserted from the slit 95 toward the rear waist region 83 side of the pants 80. Is interposed between the pants 80 and the fixed sheet 92. Next, the inner surfaces of the free front and rear portions 74 and 75 of the connecting sheet 71 are fixed to the outer surface of the fixed sheet 92 via the hook members 76 and 77. The front area 24 and the intermediate area 25 of the pad 20B are fixed to the fixed sheet 92. The rear region 26 of the pad 20 </ b> B is positioned between the pants 80 and the fixed sheet 92 without being fixed to the fixed sheet 92. The front region 24 and the intermediate region 25 are located in a substantially front half of the crotch region 82 of the pants 80, and the rear region 26 is located in a substantially rear half of the crotch region 82 of the pants 80. After the pad 20B is attached to the pants 80, the pants 80 are attached to the wearer. Excretion excreted during wearing of the pants 80 passes through the opening 31 and is accommodated in the first space 32 of the pad 20 </ b> B, and is absorbed and held in the core 23.

  In the pad 20 </ b> B, the horizontal central portion 33 of the first sheet 21 protrudes upward from the core 23 along the vertical center line M <b> 1, and a first space is formed between the horizontal central portion 33 of the first sheet 21 and the core 23. Since the second space 34 that is located above the portion 32 and extends in the vertical direction is formed, even if the first sheet 21 and the core 23 come into contact with each other and the first space 32 is blocked, the excrement is in the second space. 34, the intermediate region 25 of the pad 20B moves to the front and rear regions 24 and 26, and the excrement can be efficiently absorbed and retained throughout the core 23. In the pad 20 </ b> B, the opening peripheral portion 35 that protrudes upward from the core 23 forms a barrier against excrement, so that excrement does not get over the opening peripheral portion 35, and excrement accommodated in the first space 32 is not contained. There is no leakage from the opening 31 to the outside of the pad 20B. Since the mount 36 has higher rigidity than the first and second sheets 21 and 22 in the pad 20B, even if pressure is applied in the thickness direction of the pad 20B, the three-dimensional shape of the opening peripheral portion 35 is increased by the rigidity of the mount 36. The shape is maintained, the opening peripheral edge 35 is not easily crushed, and the opening peripheral edge 35 does not lose its function as a barrier against excrement.

  In the pad 20B, both side portions 47 of the front wall 43 extending between the first and third folding lines 39, 41 support the pressure applied in the thickness direction of the pad 20B together with the side walls 44, and the second and fourth folding lines 40 are provided. , 42, both side portions 49 of the rear wall 45 support the pressure applied in the thickness direction of the pad 20B together with the side walls 44, so that the buckling strength of the mount 36 against the pressure applied in the thickness direction of the pad 20B is improved. The mount 36 is not easily crushed, and the three-dimensional form of the opening peripheral edge 35 is reliably maintained by the mount 36. Further, since both side walls 44 of the mount 36 are attracted inward in the lateral direction of the pad 20B by the contraction force of the spacer 51, the three-dimensional form of the mount 36 is reliably maintained by the spacer 51, and the upper side of the core 23 is The three-dimensional form of the opening peripheral edge 35 that is convexly convex is reliably maintained by the mount 36 and the spacer 51. Even if the pad 20B is subjected to a large pressure in the thickness direction and the opening peripheral portion 35 is crushed and the mount 36 is flattened, when the pressure is released, the mount 36 is immediately formed into a three-dimensional form by the contraction force of the spacer 51. Thus, the opening peripheral portion 35 is restored to a three-dimensional form that protrudes upward from the core 23.

  In the pad 20B, recessed portions 50 and 79 are formed in the central portion 48 of the rear wall 45 of the mount 36 and the free rear portion 75 of the connecting sheet 71, and the second space 34 extends to the recessed portions 50 and 79. Therefore, the form of the first sheet 21 that protrudes upward from the core 23 in the recessed portions 50 and 79 can be maintained, and the rear wall 45 and the free rear portion 75 do not block the second space 34, and excrement Reliably passes through the second space 34 to the rear region 26 of the pad 20B. The pad 20B has a bag shape in which the rear area 26 spreads in the lateral direction toward the rear in the vertical direction of the pad 20B. Therefore, the waste storage capacity of the first space 32 in the rear area 26 is large, and the pad 20B is being used. Even if a large amount of excrement is excreted, all of the excrement can be accommodated in the first space 32 of the rear area 26. In the pad 20B, both side walls 44 of the mount 35 are tapered from the rear wall 45 toward the front wall 43, and the area of the front wall 43 is smaller than that of the rear wall 45. Therefore, when the pad 20B is attached, the pad 20B is mounted. The front wall 43 and the both side walls 44 of 36 will fit in a wearer's crotch part, and the opening peripheral part 35 will not be bulky in a crotch part.

  When the pad 20B is attached to the pants 80 via the connecting sheet 71, the front region 24 and the intermediate region 25 are positioned on the outer surface of the fixed sheet 92 and fixed to the sheet 92. Is not directly transmitted to the pad 20B, and even if the pants 80 are moved by the wearer's movement, the pad 20B does not move following it. Even if the pants 80 are deviated from the wearing position during wearing, the pad 20B is not deviated by the pants 80, and the contact state of the pad 20B with the wearer's skin can be maintained. It is not excreted outside 20B. Since the rear area 26 of the pad 20B is located between the pants 80 and the fixing sheet 92, even if the wearer's body pressure is applied to the crotch area 82 of the pants 80, the rear area 26 of the pad 20B is not easily crushed. The excrement accommodated in the first space 32 of the rear area 26 does not leak from the opening 31. The pad 20B containing the excrement can be removed from the pants 80 and discarded, and only the pad 20B can be replaced. Therefore, the pants 80 can be used repeatedly.

  In addition, when the pants 80 are worn, the circumferential edge 88 of the waistline is expanded by the wearer's torso, so that the fixed sheet 92 having elastic stretchability is extended in the vertical direction, and the fixed sheet 92 contracts. Since the pad 20B is pressed against the wearer's skin with force, the contact state of the pad 20B with the wearer's skin can be reliably maintained. Furthermore, since the free intermediate portion 94 of the fixed sheet 92 is spaced upward from the crotch region 82 of the pants 80, the rear region 26 of the pad 20B interposed between the pants 80 and the fixed sheet 92 is crushed by the sheet 92. There is nothing, and the leakage from the opening 31 of the excrement accommodated in the 1st space 32 of the rear area 26 can be prevented reliably.

  In the pad 20B, the rigidity value of the mount 36 is in the range of 2 to 40 mN · m. When the stiffness value of the mount 36 is less than 2 mN · m, the mount 36 is easily crushed when the pressure is applied in the thickness direction of the pad 20 </ b> B, and the shape of the opening peripheral edge 35 that protrudes upward from the core 23 is maintained. I can't. When the stiffness value of the mount 36 exceeds 40 mN · m, the opening peripheral edge portion 35 that comes into contact with the skin of the wearer during wearing of the pad 20B gives an unpleasant stimulus to the wearer. The rigidity value of the mount 36 was measured according to the Taber method (JIS P 8125). The measuring method is the same as that of the mount of FIG.

  In the pad 20B, the lateral extensional stress of the spacer 51 is in the range of 0.01 to 1.5N. If the elongation stress of the spacer 51 is less than 0.01 N, the side walls 44 of the mount 36 cannot be sufficiently pulled in the lateral direction of the pad 20B due to the contraction force of the spacer 51. When the extension stress of the spacer 51 exceeds 1.5 N, both side walls 44 of the mount 36 that are drawn in the lateral direction of the pad 20B by the contraction force of the spacer 51 come into contact with each other, and the opening 31 closes its mouth. There is. The method for measuring the extension stress of the spacer 51 is the same as that of the spacer 51 of FIG.

  In addition to the illustrated composite sheet, the first and second sheets 21 and 22 include either a hydrophobic fiber nonwoven fabric, a gas-permeable liquid-impermeable plastic film, or a composite nonwoven fabric obtained by laminating two or more hydrophobic fiber nonwoven fabrics. It can also be used. The first and second sheets 21 and 22 include a composite nonwoven fabric (SM nonwoven fabric, SMS nonwoven fabric) in which a spunbond nonwoven fabric having high strength and good flexibility is superposed on both sides or one side of a melt-blown nonwoven fabric having high water resistance. SMMS nonwoven fabric) can also be used. The spacer 51 can be made of a stretchable fiber nonwoven fabric. For the connection sheet 71, any one of cellulose sponge, nylon sponge, styrene foam, fiber nonwoven fabric, and plastic film can be used in addition to urethane foam. A non-stretchable fiber nonwoven fabric can also be used for the fixing sheet 92. The spacer 51 and the fixing sheet 92 are made of crimped fibers obtained by melting and spinning a thermoplastic synthetic resin of polypropylene, polyethylene, or polyester on at least one surface of a hydrophilic and stretchable fiber nonwoven fabric made of thermoplastic elastomer resin fibers. It is also possible to use a composite nonwoven fabric obtained by superposing hydrophilic fiber nonwoven fabrics.

  As the fiber nonwoven fabric, a nonwoven fabric produced by each method of spunlace, needle punch, melt blown, thermal bond, spunbond, and chemical bond can be used. Polyester-based, polyacrylonitrile-based, polyvinyl chloride-based, polyethylene-based, polypropylene-based, and polystyrene-based fibers can be used for the constituent fibers of the nonwoven fabric. As the constituent fibers, core-sheath type composite fibers, parallel type composite fibers, atypical hollow fibers, microporous fibers, and bonded type composite fibers can also be used. As the stretchable fiber nonwoven fabric, a nonwoven fabric manufactured by melt blown or spunbond manufacturing methods can be used. As the constituent fiber of the stretchable nonwoven fabric, a stretchable fiber obtained by melting and spinning a thermoplastic elastomer resin can be used.

  Virgin paper or used paper can be used for the mount 36. There is no particular limitation on virgin paper and waste paper, art paper, colored paperboard, coated paper, kraft paper, glassine paper, Kent paper, building paper, cotton paper, high quality paper, medium quality paper, white paperboard, drawing paper, moisture-proof paper, bond Paper, marble paper, chipball, decorative board base paper, recycled paper, and the like can be used.

  For fixing the first and second sheets 21 and 22, fixing the mount 36 to the first sheet 21, bonding the core 23 to the second sheet 22, and fixing the spacer 51 to the mount 36, an adhesive or heat seal is used. It is possible to use heat welding means such as sonic seal. As the adhesive, a hot-melt adhesive, an acrylic adhesive, or a rubber adhesive can be used.

  In the pads 20 </ b> A and 20 </ b> B, the opening 31 is formed in the front region 24 and the intermediate region 25, but it is sufficient that the pad 20 </ b> A and 20 </ b> B is formed in at least the intermediate region 25. In the pads 20 </ b> A and 20 </ b> B, the spacer 51 may not be attached to the mount 36. Further, the mount 36 and the spacer 51 can be omitted. In the pads 20A and 20B, the mount 36 is bent only by the first and second folding curves 39 and 40, and the third and fourth folding curves 41 and 42 may not be formed on the mount 36. In the pad 20 </ b> B, hook members 76 and 77 are attached to the inner surface of the connecting sheet 71, but a pressure-sensitive adhesive can be applied to the inner surface of the connecting sheet 71 instead of the hook members 76 and 77. When applying a pressure-sensitive adhesive, it is necessary that the adhesive is covered and protected by a release paper. In the pants 80, the slit 95 is formed in the fixed sheet 92, but an elliptical opening (insertion opening) that is long in the lateral direction can be formed in the sheet 92 instead of the slit 95. The pants 80 may be made of a woven fabric or a knitted fabric instead of the nonwoven fabric.
