It relates to excreta containing products.

  A waste-containing product is used inside an underwear or disposable diaper to absorb urine or stool excreted by an elderly person or a urinary incontinence patient, or a waste-containing product itself is used as a disposable diaper. The

  Some conventional waste-containing products have a bag body that absorbs excrement as described in the following Patent Documents 1 to 3, and an opening is formed in the bag body. This type of excrement-containing product requires that the peripheral portion of the opening is in close contact with the body, and if a gap is formed between the peripheral portion and the body, the excrement is placed inside the bag body. It does not enter effectively and is likely to leak outside.

  The one described in Patent Document 1 is a diaper for infants or incontinent persons, which is formed into a bag shape with a top sheet and a back sheet, and an absorbent core is provided therein. An opening is formed in the top sheet, and a spacer is disposed around the top sheet inside the top sheet. The spacer is formed by filling the outer cover with a non-absorbing spherical polymer.

  As described above, the conventional waste-containing product attempts to bring the peripheral edge of the opening into close contact with the body by arranging a spacer or the like on the peripheral edge of the opening of the bag. However, since this type of excrement-containing product tends to collapse when used in close contact with the body, excrement such as urine and stool is difficult to enter the bag, and excrement is likely to leak to the outside. ing.

  In addition, since the spacers, cardboard, and elastic materials described in each of the above patent documents are all difficult to be deformed flexibly, there is a limit in reliably bringing the peripheral edge of the opening into close contact with the body through these. .

  SUMMARY OF THE INVENTION The present invention solves the above-described conventional problems, and provides a waste-containing product that easily forms a space for receiving excrement in the bag body, with the peripheral edge portion of the opening of the bag body being in close contact with the body. It is an object.

The present invention, in a waste containing product having a bag body having an opening, and a liquid absorber installed inside the bag body,
An elastically deformable elastic wall extending from the peripheral edge of the opening toward the inside of the bag body is provided.

  In this excrement containing product, since the elastic wall extends from the periphery of the opening portion toward the inside of the bag body, the opening of the bag body is caused by the elastic force of the elastic wall when worn on the body. The peripheral part of the part or the top part facing the skin side of the elastic wall tends to adhere closely to the excretory part of the body. Further, since the space is maintained inside the bag body on the back side of the opening by the elastic wall, the excretion part such as urine and stool excreted from the excretion part is surely accommodated in the bag body. Become.

  In this invention, it is preferable that the said elastic wall is a shape where the opening dimension of the vertical direction and a horizontal direction becomes gradually wide toward the inside of a bag body.

  Since the elastic wall has a shape in which the interval is widened toward the inside of the bag body, excrement is easily accommodated in the bag body. Further, when pressure is applied from the body, the elastic wall is easily bent and deformed, and an excessive feeling of pressure is not given to the body.

  Further, according to the present invention, the top part facing the skin side of the elastic wall has a vertically long shape in which the opening dimension in the vertical direction is larger than the opening dimension in the horizontal direction, and the front end part and the rear end part facing the vertical direction of the top part are , It protrudes to the skin side from the middle part.

  As described above, when the top portion facing the skin side of the elastic wall is vertically long and the front and rear end portions are raised from the middle portion, the opening of the bag body or the top portion has a shape in the front-rear direction of the body. It becomes easy to closely adhere along, and excrement is reliably captured in the bag body, and leakage to the outside hardly occurs.

  Moreover, the said bag body has the opposing bottom part which opposes the said elastic wall, and the height dimension from the opposing bottom part in the said intermediate part is 0 of the height dimension from the opposing bottom part in the said front-back end part. .8 times or less and 0.2 times or more.

  Furthermore, the minimum value of the height dimension is preferably 10 mm, and the maximum value is preferably 100 mm.

  When the top portion facing the skin side of the elastic wall has the above structure, the opening portion of the bag body or the top portion of the elastic wall is always easily adhered along the front-rear direction around the body excretion portion.

  Moreover, in this invention, Preferably, the top part which faces the skin side of the said elastic wall is formed of the cushion body.

  The cushion body is formed, for example, by wrapping a fiber assembly in a sheet, and when applying force to the cushion body and applying force in a direction along the wall surface to the wall body of the elastic wall In addition, the cushion body is deformed with a weaker force than the wall body.

  If the cushion body is provided in this way, even if the top of the elastic wall is in direct contact with the body, the contact feeling is soft and the wearing feeling is good.

  In the present invention, the top of the elastic wall facing the skin may be formed so that the edge of the wall main body does not face the skin.

  If the top of the elastic wall facing the skin is deformed as described above, the edge of the wall body does not give the skin a sense of resistance.

  In the present invention, the elastic wall may protrude to the skin side with respect to the opening of the bag, and the top of the elastic wall may contact the skin, or the top may be closer to the bag than the opening of the bag. It may be located inside.

  Furthermore, in this invention, it can comprise as a liquid guide being provided in the area | region enclosed by the said elastic wall.

  The conducting liquid is a fiber assembly. For example, the fiber assembly is a bundle of fibers opened from a tow (TOW), or the fiber assembly is formed of a plurality of nonwoven fabrics.

  Moreover, it is preferable that the said liquid guide protrudes toward the outer side of a bag body rather than the top part which faces the skin side of the said elastic wall.

  When the liquid guide is provided, the liquid guide comes into close contact with the excretory part, and urine is reliably accommodated in the bag body through the excretion part.

  In the present invention, the peripheral edge of the opening of the bag body or the top of the elastic wall facing the skin side can be easily adhered to the periphery of the excretory part of the body. Further, since the space is easily secured in the bag body by the elastic wall, the excrement is easily stored in the bag body, and leakage to the outside hardly occurs.

Further, the exterior sheet 3 is flattened inside the rear edge 3c of the exterior sheet 3 and joined by a seal line 4 extending in the lateral direction (X direction). The exterior sheet 3 is flattened inside the front edge portion 3d of the exterior sheet 3 and joined by a seal line extending in the lateral direction (X direction). As shown in FIG. 2, the front portion of the exterior sheet 3 is folded toward the back surface of the bag body 2, and the front edge portion 3 d is overlapped on the back surface side of the bag body 2.

  The bag body 2 formed as described above has a rectangular opposed bottom portion 5 formed on the back side and a skin facing portion 6 formed on the front side. In the skin facing portion 6 of the bag body 2, an opening facing the facing bottom portion 5 is formed. The opening is formed so as to be surrounded by the opening edge 3 e and the opening edge 3 f of the exterior sheet 3. The opening edge 3e is formed by cutting the right edge 3a of the exterior sheet 3 into a concave shape, and the opening edge 3f is formed by cutting the left edge 3b of the exterior sheet 3 into a recess. .

  As shown in FIGS. 2 and 4, in the bag body 2, a liquid absorber 8 is provided inside the opposed bottom portion 5. The liquid absorber 8 has a rectangular shape, and is bonded and fixed to the exterior sheet 3 inside the opposed bottom portion 5.

  As shown in FIGS. 1 and 2, an elastic wall 111 is provided from the opening edge portions 3 e and 3 f toward the inside of the bag body 2. The elastic wall 111 is provided over the entire circumference of the opening formed by the opening edges 3e and 3f. However, the present invention is not limited to the elastic wall 111 provided around the entire periphery of the opening, but the elastic wall 111 is provided at a part of the periphery of the opening. May be. The elastic wall 111 is preferably provided at 60% or more of the peripheral length of the opening.

  The elastic wall 111 includes a wall body 11 and a cushion body 15 attached to the upper edge portion 11a of the wall body 11. As shown in FIG. 2, the upper edge portion 11 a of the wall body 11 is located inward of the bag body 2 closer to the opposed bottom portion 5 than the opening edge portions 3 e and 3 f, and is below the elastic wall 111. The skirt portion 11 b of the wall body 11 that is an edge portion is provided at a position that is closest to the inner surface of the opposed bottom portion 5.

  The gap in the vertical direction (Y direction) of the skirt portion 11b is wider than the opening dimension in the vertical direction (Y direction) of the upper edge portion 11a, and the horizontal direction (X direction) of the upper edge portion 11a. The distance in the lateral direction (X direction) at the skirt 11b is wider than the opening size at. That is, the elastic wall 111 has a tapered shape such that the inner space gradually widens from the opening edge portions 3e and 3f toward the opposed bottom portion 5.

  The accommodation port 7 is formed to be surrounded by the cushion body 15. The upper surface of the cushion body 15 is the top 111a of the elastic wall 111.

  As shown in FIG. 2, the cushion body 15 is formed of a cushion material 16 and a sheet 17 that wraps the cushion material 16. The sheet 17 wraps the cushion material 16, and an inner edge 17 a and an outer edge 17 b are bonded to the inner surface and the outer surface of the wall body 11.

  The cushion body 15 has a substantially circular cross section, and is disposed along the entire periphery of the upper edge portion 11 a of the wall body 11 and along the entire periphery of the peripheral edge portion of the accommodation port 7. The opening edge 3 e and the opening edge 3 f of the exterior sheet 3 are located on the outer peripheral surface of the cushion body 15, and the exterior sheet 3 is bonded and fixed to the cushion body 15. The exterior sheet 3 may be bonded to the outer surface of the wall body 11, and the exterior sheet 3 may be bonded to both the outer peripheral surface of the cushion body 15 and the outer surface of the wall body 11.

  The opening portion surrounded by the opening edge portions 3e and 3f and the accommodation port 7 surrounded by the cushion body 15 both have an opening size in the vertical direction (Y direction) and an opening size in the horizontal direction (X direction). It is a vertically long shape larger than that.

  As shown in FIG. 2, in the front end portion 7 a of the storage port 7, the vertical direction from the inner surface of the opposed bottom portion 5 to the top portion of the cushion body 15, that is, the front end portion of the top portion 111 a of the elastic wall 111 (the vertical direction relative to the inner surface of the opposed bottom portion 5). ) Is the height dimension H1, a similar height dimension at the rear end 7b of the peripheral edge of the storage port 7 is H2, and a similar height dimension is H3 at the intermediate portion (center portion) 7c in the front-rear direction of the storage port 7. And

  The height H3 is smaller than the height dimension H1 and the height dimension H2. As a result, the cushion body 15, that is, the top portion 111 a of the elastic wall 111 positioned at the peripheral edge of the accommodation port 7, the front end portion 7 a and the rear end portion 7 b are raised on the skin side, and the intermediate portion 7 c is the opposed bottom portion 5. The cushion body 15 is curved in a concave shape in the vertical direction.

  The minimum value of the height dimension H3 at the intermediate portion 7c is 10 mm, preferably 15 mm. The maximum heights H1 and H2 at the front end portion 7a and the rear end portion 7b are 100 mm, preferably 80 mm, and more preferably 60 mm. That is, the height dimension from the inner surface of the opposed bottom portion 5 to the upper surface of the cushion body 15, that is, the top portion 111a of the elastic wall 111 is 10 to 100 mm, preferably 10 to 80 mm, and more preferably 10 to 60 mm.

  The height dimension H3 is 0.8 times or less and 0.2 times or more with respect to the height dimension H1 and the height dimension H2.

  FIG. 5 is a cross-sectional view of the wall main body 11 and the cushion body 15 taken along the longitudinal center line Oy shown in FIG.

  The wall body 11 is easily bent and deformed as shown in FIG. 4 when a buckling load in the direction along the wall surface is applied, and is easily elastically restored to its original shape when the load is removed. It is formed of foamed resin materials such as urethane, olefin, and styrene, paper materials, relatively thick nonwoven fabrics, or a laminate of a plurality of nonwoven fabrics bonded together. The wall body 11 preferably has a surface coated with a water repellent.

  As shown in FIG. 5, the skirt part 11b of the wall main body 11 extends substantially linearly in the horizontal direction, and the upper edge part 11a of the wall main body 11 has a concave shape in which an intermediate part is recessed from the front and rear end parts. . That is, the height dimension in the vertical direction from the opposed bottom part 5 of the wall body 11 at the front end part 7a of the storage port 7 is Ha, the height dimension at the rear end part 7b is Hb, and the height at the intermediate part 7c. When the dimension is Hc, the height dimension Hc is lower than the height dimension Ha and the height dimension Hb, and Hc is 0.8 times or less of Ha or Hb and 0.2 times or more. As a result, as shown in FIG. 1, the cushion body 15 is curved in a concave shape in the longitudinal direction at the peripheral edge of the accommodation port 7.

  As shown in FIG. 3, when the excrement containing product 1 is installed in the crotch portion 21 of the body and the bag body 2 is attached to the curved shape in the front-rear direction of the crotch portion 21, the opposed bottom portion of the bag body 2. 5 receives pressure from underwear 25. Since the skirt 11b of the wall body 11 extends linearly in the horizontal direction, the pressing force F shown in FIG. 5 acts on the front end of the skirt 11b due to the compression force. The wall body 11 is deformed, and the cushion body 15 is bent and deformed in a large concave shape in the vertical direction. Therefore, the cushion body 15 located at the peripheral edge of the accommodation port 7 is likely to adhere closely along the front-rear direction along the protruding curved surface of the crotch portion 21.

  Moreover, the shape shown in FIG. 6 may be sufficient as an elastic wall. In the elastic wall 111A shown in FIG. 6, the upper edge portion 11a of the wall main body 11A extends linearly in the horizontal direction, and the hem portion 11b of the wall main body 11A has an intermediate portion rather than the longitudinal front and rear end portions. The shape is recessed toward the upper edge portion 11a. As a result, the height dimension Hf at the intermediate part 7c is lower than the height dimension Hd in the vertical direction of the wall body 11A at the front end part 7a of the storage port 7 and the height dimension He at the rear end part 7b. . The height dimension Hf is 0.8 times or less and 0.2 times or more with respect to Hd or He.

  When the excreta containing product using the elastic wall 111A shown in FIG. 6 is in a natural state as shown in FIG. It is substantially parallel to the opposed bottom 5. However, when the excrement containing product is installed in the crotch part of the body as shown in FIG. 3 and receives a compressive force from the underwear 25, the compressive force causes the hem 11b of the wall main body 11 as shown in FIG. An upward force F acts on the front end portion and the rear end portion. And the wall main body 11 deform | transforms and the peripheral part of the accommodating port 7 becomes concave shape so that the intermediate part 7c faces the opposing bottom part 5 rather than the front-end part 7a and the rear-end part 7b, and the peripheral edge of the accommodating port 7 It becomes easy for the cushion body 15 located in the body to follow the shape of the crotch part of the body.

FIG. 7 is a perspective view illustrating the structure of the cushion body 15.
When a force is applied to the cushion body 15 and a force along the wall surface (buckling load) is applied to the wall body 11, the force that compresses and deforms the cushion body 15 causes the wall body 11 to bend and deform. It is set so as to be weaker than the force to be applied. That is, the wall body 11 functions to maintain the shape of the peripheral edge of the storage port 7, press the peripheral edge of the storage port 7 against the crotch portion, and further form a space on the back side of the storage port 7. On the other hand, the cushion body 15 functions so that the peripheral edge portion of the accommodation port 7 is in soft contact with the crotch portion 21 of the body.

  The cushion body 15 shown in FIG. 7 is a separate body from the wall main body 11, and the cushion material 16 is a bundle of fibers opened from tow (TOW). The fiber is formed of polyethylene (PE) resin, polypropylene (PP) resin, polyethylene terephthalate (PET) resin or the like, or a composite synthetic fiber combining the above resins, and the fineness is about 1.1 to 11 dtex. . The fibers opened from the tows are not bonded to each other, but the individual fibers are crimped fibers, and the fibers are intertwined so that the shape as a bundle can be maintained.

  In the cushion material 16, individual fibers continuously extend along the peripheral edge of the accommodation port 7, and the bundle of fibers is wrapped by a sheet 17, and an inner edge 17 a and an outer edge of the sheet 17. The portion 17b is bonded to the inner surface and the outer surface of the wall body 11. The sheet 17 is an air-through nonwoven fabric obtained by fusing the synthetic resin fibers formed of the various resins with hot air, a spunbond nonwoven fabric, a melt blown nonwoven fabric, or a resin film formed of various synthetic resin fibers. The sheet 17 is hydrophobic and liquid-impermeable, and is preferably used that has been subjected to a water-repellent treatment by applying a water-repellent agent to the surface.

  Since the fiber bundle opened from the tow is crimped and entangled, it can be elastically contracted when a force f is applied from above.

  FIG. 8 shows an example in which the cushion body 15A is formed integrally with the wall body 11B. The wall body 11B is formed by stacking and adhering a foamed resin material or a plurality of nonwoven fabrics. The wall body 11B is formed by folding a sheet of foamed resin material or the like into two at the upper edge. A plurality of slits 18 are formed at the upper edge of the wall body 11 to form a cushion material 16A in which the wall body 11B is cut into thin pieces. The cushion material 16 </ b> A is bundled and covered with a sheet 17.

  The cushion material is not limited to those shown in FIGS. 7 and 8, but a low-density air-through nonwoven fabric, a foamed resin material, a soft resin material other than the foamed resin, a synthetic rubber, a urethane resin, cotton, It can be formed of natural rubber or the like.

  The exterior sheet 3 forming the bag 2 is a resin film, a spunbond nonwoven fabric, a meltblown nonwoven fabric, a multilayer nonwoven fabric in which a spunbond nonwoven fabric and a meltblown nonwoven fabric are laminated, and is hydrophobic and liquid-impermeable. It is. Moreover, the exterior sheet 3 is preferably used in which at least the outer surface of the bag body 2 is water-repellent.

  The liquid absorber 8 is formed by forming air bags by laminating pulp by an air raid method and bonding them with a binder, a laminate of absorbent paper, or a liquid permeable sheet to form a plurality of bags. It is one that encloses a superabsorbent resin (SAP) inside, or a combination of these absorbers.

  FIGS. 3 and 4 show a state in which the excreta containing product 1 is installed in the crotch portion 21 of the female body 20. The front edge portion 3d of the bag body 2 is directed to the abdomen side, the rear edge portion 3c is directed to the buttocks side, the female urine portion faces the storage port 7, and the cushion body 15 is located around the urine portion at the crotch portion 21. To.

  As shown in FIG. 1, the cushion body 15 positioned at the peripheral edge of the storage port 7 is curved in a concave shape in the longitudinal direction so that the cushion body 15 faces the skin side at the front end portion 7a and the rear end surface 7b. Therefore, the cushion body 15 comes to follow the surface shape of the crotch portion 21. As shown in FIG. 3, when an underwear 25 (or a disposable diaper) is worn on the outside of the excrement containing product 1, the excreta containing product 1 is pressed against the crotch portion 21 by the underwear 25. With this pressure, the cushion body 15 is further curved in a concave shape in the vertical direction as indicated by a broken line in FIG. 5 or FIG. Therefore, the cushion body 15 is easily adhered to the crotch portion so as not to form a gap with the periphery of the excretory portion.

  As shown in FIG. 4, the cushion body 15 elastically contracts and hits the crotch portion 21, and the wall main body 11 can be freely bent and deformed, so that the cushion body 15 can be securely adhered around the excretory portion in the crotch portion 21. become. Further, since the cushion body 15 is soft and can be elastically deformed with respect to the compressive force, and the wall body 11 can also be elastically deformed so that the surface thereof is curved, the crotch portion 21 is soft against the skin.

  As shown in FIG. 4, the wall main body 11 extends from the opening edges 3 e and 3 f toward the inside of the bag body 2, and the height from the opposed bottom 5 of the bag body 2 to the top of the cushion body 15 is high. Since it is 10 mm or more, the bag body 2 is not completely crushed on the back side of the storage port 7, and a space is secured in the bag body 2 inside the storage port 7. Therefore, when urine is excreted, the urine reliably passes through the storage port 7 and enters the bag body 2, and is reliably absorbed by the liquid absorber 8 in the bag body 2. Since urine is given to the space on the back side of the storage port 7 and is absorbed by the liquid absorber 8, it is difficult for urine to overflow from the storage port 7 to the outside.

  FIG. 9 shows the excreta containing product 100 of the second embodiment of the present invention, and is a cross-sectional view cut along the same cut surface as shown in FIG.

  The bag body 102 of the excrement containing product 100 is formed of an upper exterior sheet 103 a and a lower exterior sheet 103 b made of the same material as the exterior sheet 3. Both the upper exterior sheet 103a and the lower exterior sheet 103b have a planar shape such as a rectangle or an oval shape, and the upper exterior sheet 103a and the lower exterior sheet 103b are bonded to each other at the fixing portion 104 at the peripheral edge.

  The lower exterior sheet 103b forms an opposed bottom 5 and a liquid absorber 8 is provided on the inner side. In the skin facing portion 6, an opening surrounded by the opening edge 103c of the upper exterior sheet 103a is formed.

  The elastic wall 111B is entirely formed of the same material as that of the wall body 11, the skirt 11b is located close to the liquid absorber 8, and the top 111a facing the skin side is from the opening of the bag body 102. Also in the position protruding to the skin side. The upper exterior sheet 103a is adhered to the outer surface of the elastic wall 111B at the opening edge 103c.

  The elastic wall 111B includes a wall main body 11D formed in a tapered shape so that the opening size gradually increases toward the inside of the bag body 102, and a deformed portion in which a part of the wall main body 11D is deformed at the top 111a. 11E. The deformed portion 11E is bent so that its cross section is circular or oval, so that the edge 11e of the wall body 11D does not face the skin side. A portion surrounded by the deforming portion 11E is the accommodating port 7.

  In the excrement containing product 100, the elastic wall 111B protrudes relatively long from the opening of the bag body 102 toward the skin side, and the deformed portion 11E hits the periphery of the excretory portion of the body. And the deformation | transformation part 11E becomes easy to closely_contact | adhere to skin by the comparatively soft elastic deformation of the elastic wall 111B.

  In addition, the material which forms the wall main body 11D in the said deformation | transformation part 11E may be made thin, and the deformation | transformation part 11E may function as a cushion body.

10A and 10B are cross-sectional views showing modifications of the elastic wall 111B shown in FIG.
In the elastic wall 111B shown in FIG. 10A, a part of the wall main body 11D is bent into a rectangular cross section at the top 111a of the wall main body 11D to form a deformed portion 11F, and the elastic wall shown in FIG. In 11B, in the top part 111a of the wall main body 11D, a part of the wall main body 11D is formed into a T-shaped cross section to form a deformed part 11G.

  FIG. 11 shows an excreta containing product 101 according to the third embodiment of the present invention, and is an exploded perspective view showing the bag body 2 and the liquid guide 30 separately. FIG. 12 is a cross-sectional view taken along line XX showing a state in which the liquid guiding liquid 30 is stored in the bag body 2, and FIG. 13 is a state in which the liquid guiding liquid 30 is stored in the bag body 2 and attached to the crotch portion 21. It is the same sectional view as FIG. 4 which shows a state.

  The bag body 2 of the excrement containing product 101 has the same structure and the same shape as the first embodiment shown in FIG.

  Inside the bag body 2, a liquid guide 30 is stored. The liquid guide 30 is hydrophilic and has a large number of voids therein, and has a structure capable of guiding urine inside. As shown in FIG. 11, the liquid guide 30 has a raised portion 31 and a flat portion 32 that is continuous with the skirt portion of the raised portion 31. As shown in FIGS. 12 and 13, when the guiding liquid 30 is stored in the bag body 2, the lower surface 32 a of the guiding liquid 30 comes into contact with the liquid absorber 8, and the raised portion 31 is located on the back side of the storing port 7. In the space surrounded by the elastic wall 111. Further, the flat portion 32 extends further rearward in the bag body 2 than the bottom portion 11 b of the wall body 11.

  In the raised portion 31, the upper surface 31a has a protruding shape, and the periphery of the raised portion 31 has a tapered shape that gradually spreads from the upper surface 31a toward the lower surface 32a. In a state where the liquid guide 30 is stored in the bag body 2, the upper surface 31 a is exposed to the outside from the storage port 7. The upper surface 31 a protrudes outward from the top portion 111 a of the elastic wall 111 (the upper surface of the cushion body 15) at least at the intermediate portion 7 c at the peripheral edge of the storage port 7, and more preferably The front end portion 7a and the rear end portion 7b of the peripheral edge also protrude outward from the top portion 111a.

  As shown in FIG. 13, when the excrement containing product 101 is installed in the crotch portion 21 of a woman, the liquid guide 30 protruding from the containing port 7 is in close contact with the excretory portion and the periphery of the female genital. The liquid guide 30 functions to guide the excreted urine to the inside of the bag body 2, and also functions to keep a space inside the bag body 2 on the back side of the accommodation port 7. The excreted urine penetrates the internal space of the liquid guiding liquid 30 and is quickly guided into the bag body 2 and absorbed by the liquid absorber 8. Since the cushion body 15 located on the outer periphery of the liquid guide 30 is in close contact with the crotch portion 21 while the liquid guide 30 is in close contact with the crotch portion 21, the urine can be reliably accommodated in the bag body 2 and hardly leaked to the outside. .

  In the embodiment shown in FIGS. 11 to 13, the liquid guide 30 is formed of a bundle of fibers opened from tow (TOW). This fiber is formed of polyethylene (PE) resin, polypropylene (PP) resin, polyethylene terephthalate (PET) resin, or a composite synthetic fiber combining the above resins, and the fineness is about 1.1 to 11 dtex. is there. As the fiber, a surface-treated surfactant is applied to the surface, or a surface-treated surfactant is applied to the inside of the fiber to perform a hydrophilic treatment.

  The fibers opened from the tow continuously extend without interruption, and the fibers are not bonded to each other. However, since the individual fibers are crimped fibers, the fibers are intertwined so that the shape of the liquid guide 30 can be maintained.

  In the illustrated embodiment, when the fiber is opened from the tow, the fiber bundle is expanded in the width direction to form a bundle of sheet-like fibers having a predetermined thickness and a predetermined width. The liquid guide 30 is formed by stacking a plurality of layers in a vertical direction (Z direction). Therefore, in this liquid guiding liquid 30, each fiber extends in the longitudinal direction (Y direction). In the fiber bundle, numerous voids are formed between the crimped fibers to guide urine.

  FIGS. 14A and 14B are perspective views showing a liquid guide 40 according to another embodiment and a manufacturing process thereof.

  As shown in FIG. 14A, a plurality of water permeable sheets 41 having hydrophilicity and voids inside are stacked. As described above, the water-permeable sheet 41 is a bundle of fibers that are spread from the tow so as to have a certain thickness. Or the laminated body of a pulp and the air through nonwoven fabric formed with the synthetic resin fiber by which the hydrophilic process was carried out may be sufficient. By folding a plurality of the water permeable sheets 41, the liquid guide 40 shown in FIG. 14B is formed.

  When the water permeable sheet 41 is formed of a bundle of fibers, the sheet surface of each water permeable sheet 41 comes to rise from the opposed bottom 5 toward the accommodation port 7. The fibers extend substantially vertically from the opposed bottom 5 toward the receiving port 7. Therefore, when a large amount of urine is excreted in a short time, it becomes easy to guide the urine toward the liquid absorber 8 located inside the opposed bottom portion 5.

  FIGS. 15A and 15B are perspective views showing a liquid guide 50 and a manufacturing process thereof according to still another embodiment.

  The water-permeable sheet 51 shown in FIG. 15A is the same as the water-permeable sheet 14 shown in FIG. However, the water-permeable sheet 51 is cut into a trapezoid (or a triangle) in a state where one or a plurality of sheets are stacked, that is, the width dimension gradually decreases from the long side 51a to the short side 51b.

  As shown in FIG. 15 (B), the water-permeable sheet 51 is folded alternately in turn by folding lines L1, L2, L3, L4 parallel to the sides 51a, 51b, and the folded body shown in FIG. 15 (B). 52 is formed. When the folded body 52 is bent, a liquid guide 50 shown in FIG. 15C is formed. The liquid guide 50 has a tapered shape in which the long side 51a side is thick and gradually narrows toward the short side 51b. Therefore, it becomes easy to match the shape of the space surrounded by the wall body 11 in the bag body 2. This liquid guiding liquid 50 also has a sheet surface and a fiber direction perpendicular to each other, so that urine can be easily guided to the liquid absorber 8.

FIG. 16 shows still another embodiment of the liquid guiding liquid.
16 (A) is formed of a bundle of fibers opened from the tow as shown in FIG. 11, but from the upper surface 71a protruding from the storage port 7 to the lower surface 72a, A recess 71 is formed. The recess 71 extends in the vertical direction (Y direction). Further, the depth of the recess 71 may be up to the middle of the lower surface 72a, or may reach the lower surface 72a.

  For example, in the liquid guide 70 formed of a bundle of fibers, the depression 71 is formed, so that urine can be guided to the depression 71 and easily transferred to the liquid absorber 8.

  Both the liquid guide 80A shown in FIG. 16B and the liquid guide 80B shown in FIG. The water permeable sheet 81 is the same as the water permeable sheet 14. The liquid guiding liquids 80A and 80B are formed by stacking the water permeable sheets 81 in the X direction and the Y direction with the sheet surface of the water permeable sheets 81 oriented vertically.

  The liquid guides 80A and 80B are also easily guided to the liquid absorber 8 when a large amount of urine is given in a short time because the sheet surface and the fibers are oriented in the vertical direction.
