Description

  The present invention relates to an ostomy pouch for collecting bodily fluids and human excreta, and in particular, an ostomy pouch that can be discarded and disposed of in a flush toilet together with excrement collected after use, and a manufacturing method thereof, and an ostomy appliance using the ostomy pouch About.

  Such ostomy pouches have been awaited for many years because there is no need for an unpleasant operation of discharging and cleaning the excrement from the pouch after use, but up until now only UK Welland Medical has been commercialized. It has not yet spread.

  Patent Document 1 relates to a product of the above-mentioned Welland Medical. In this orthosis, the ostomy pouch has a predetermined strength in the dry state during use, and after use, the base material is a disintegrating polyvinyl alcohol film that loses strength due to dissolution or disintegration caused by the water flow in the toilet. A water-resistant material for protecting from the water in the excrement is laminated on the inner surface. However, since it is necessary to discard and replace not only the ostomy pouch that becomes the inner bag after use but also all the devices including the face plate and the outer bag, there are problems in terms of ease of operation and cost.

  Patent Document 2 is based on the applicant of the present application, and a pouch that can be poured into a flush toilet made of a water-soluble film is used as an inner bag, and the inner bag can be detachably accommodated in an outer bag that can be attached to and detached from a face plate. Various forms of appliances are disclosed. In addition to an opening for allowing excrement to pass through the inner bag in common with the outer bag, an example is also disclosed in which another opening that can be opened and closed for taking out the inner bag is provided. The inner bag can be attached and detached by, for example, attaching an adhesive to the flange of the inner bag and coupling it to the face plate, forming the opening of the inner bag in a flared shape, and sandwiching the flare portion between the fitting portion of the outer bag and the face plate There are things.

  In Patent Document 3, a bag body in which a plastic film is laminated on a water-dispersible paper sheet is used as an inner bag, and an integrated bag and a water-insoluble outer bag by an easily peelable adhesive are made detachable from a face plate. Is. In order to dump the inner bag into the toilet after use, it is also necessary to discard the outer bag. Although the face plate can be reused, the cost is still inevitable.

  In Patent Document 4, an inner bag is detachably accommodated in an outer bag that can be attached to and detached from a face plate. The face plate and the outer bag can be attached and detached by an adhesive coupling portion, and the flange portion of the inner bag is sandwiched between the inner peripheral side of the coupling. For this reason, it is easy to position the flange of the inner bag and the flange of the outer bag by attaching a peelable liner with a grip surface molded to the inner bag, and after the adhesive bonding between the outer bag and the flange of the inner bag, It is designed to be connected to the face plate. However, since the flange of the inner bag is adhesively bonded even though it has a small diameter, there is a problem in picking and removing the flange of the inner bag without dirtying the hand after use in the state where the excrement is stored. is there.

  In patent document 5, a zipper fastener is attached to the outer peripheral part of an outer bag, the front surface can be opened and closed widely, and the inner bag can be easily attached to and detached from the face plate. However, a special appliance is required in which the outer bag and the face plate are integrated and a zipper fastener is attached to the outer periphery of the outer bag. The inner bag has a tear, and the flange thickness is 0.8mm or less to make it easy to flow in flush toilets, but it may be allowed in large flush toilets in Europe and the United States, but at least in Japan There are doubts about clogging of flush toilets and degradability in household septic tanks.

  Patent Document 6 is a one-piece ostomy pouch in which a face plate and a bag are integrated. The base material of the bag is made of water-soluble polyvinyl alcohol, the face plate is made of a skin protecting agent containing a hydrophilic component and a hydrophobic component, and the backing material is a laminated film of a water-soluble polymer and a biodegradable resin. It is easy to collapse by the water flow of the flush toilet. However, there is a problem in safety because the outer bag is not used. Moreover, in order to prevent the cross section of the water-soluble polyvinyl alcohol film exposed at the opening of the bag body from being damaged by contact with excrement during use, the portion including this cross section is heat sealed and insolubilized. . For this reason, there is a doubt about the discardability of this insolubilized part.

  Patent Document 7 also protects the cross section of the water-soluble polyvinyl alcohol film exposed at the opening of the bag body. In this invention, a collar is provided on the face plate corresponding to the edge of the opening of the bag body, and the edge is used. Although it does not come into contact with excrement, the edge cannot be completely protected by such a color alone. In the present invention, there is no description or suggestion about the outer bag.

  In order to solve the above-mentioned problems, the present applicant has proposed an ostomy pouch using an underwater disintegrating sheet, a manufacturing method thereof, and an ostomy appliance (Japanese Patent Application No. 2006-7494).

  ADVANTAGE OF THE INVENTION According to this invention, the problem of a prior art can be solved, and the ostomy pouch which was low cost and excellent in practicality, its manufacturing method, the usage method of an ostomy pouch, and an ostomy appliance can be provided.

  Embodiments of the present invention are described below. Note that the specific configuration and manufacturing method of the ostomy pouch and ostomy appliance will be described in the section of Examples described later.

  The ostomy pouch of the present invention comprises a bag body and a flange using an underwater disintegrating sheet in which a water-resistant layer is provided on one surface of an underwater disintegrating base material made of underwater disintegrating paper or a water-soluble resin film. The bag body is formed by joining two underwater disintegrating sheets into a bag shape by joining their peripheral edges to each other, or an underwater disintegrating sheet formed in a gusset shape, and has an opening for receiving excrement on one side. A part is provided. The flange is formed by forming an underwater disintegratable sheet-like base material into a ring shape.

  Water-disintegrating paper is water-soluble paper or water-soluble binder that dissolves quickly in hot or cold water by making fibrous carboxymethyl cellulose or by making carboxymethyl after making fibrous cellulose. This is a water-dispersed paper that is obtained by papermaking cellulose fibers and is stirred in warm or cold water to rapidly disperse the cellulose fibers. Toilet paper base paper can also be used. Underwater disintegrating paper to be used for the bag and flange should be selected appropriately for basis weight, thickness, water-soluble paper, and water-dispersed paper according to the required flexibility and strength, ease of impregnation of water-resistant materials, etc. Can do.

  The water-soluble resin film is a well-known one, and a polyvinyl alcohol film, a methyl / ethyl cellulose or the like whose saponification degree is adjusted so as to obtain an appropriate water solubility can be used.

  The water-resistant layer provided on the water-disintegrating base material is a continuous thin film that does not have cracks or pinholes even when it comes into contact with excrement when it is lined with the base material. And when the base material thrown into the water flow of the flush toilet collapses and collapses, it breaks down quickly or at least cracks. Furthermore, what has the biodegradability which decomposes | disassembles easily in the public sewage system or the septic tank separately installed in the household is preferable.

  As the material used for the water resistant layer, for example, a material mainly composed of a low molecular weight amorphous polyalphaolefin can be used as long as it is a thermoplastic resin. You may use the composition which mixed the brittle provision component with the thermoplastic resin. In this case, the thermoplastic resin may be polyethylene, polypropylene, polystyrene, polyamide, polyester, polyurethane, polylactic acid, polybutylene succinate, ethylene vinyl acetate copolymer (hereinafter “EVA”), ethylene / vinyl alcohol copolymer, etc. It is. As the component that imparts brittleness to the thermoplastic resin, for example, any component that suppresses the elongation of the thermoplastic resin and lowers the tear strength may be used. Powders such as talc, silica, titanium oxide, paraffin wax, carnauba wax And waxes such as low molecular weight polymers. The combination of the thermoplastic resin and the brittleness imparting component is preferably EVA and paraffin wax, EVA and polylactic acid, polyethylene terephthalate and low molecular weight polycaprolactan having a molecular weight of about 5,000.

  As a method of laminating a water-resistant layer on an underwater disintegratable substrate, there are a method of laminating a film such as a coating used by a hot melt coater such as a roll coater or a die coater, or a thermoplastic resin.

  In the ostomy pouch of the present invention, a water-resistant barrier member is provided along the inner peripheral surface of the opening for receiving the excrement of the bag and the flange, that is, the cross section. The structure of a barrier member should just be a thing of the shape and arrangement | positioning which excrement does not contact an underwater disintegrating base material. Moreover, the material used for a barrier member can use what is used for the water-resistant layer of a water disintegrating sheet.

  What is used for the water-resistant layer of an underwater disintegrating sheet can also be used for joining the flange and the bag. In addition, if an ostomy pouch is thrown into the water and the backed base material collapses, it can be disassembled into pieces immediately after dumping by the water flow of the flush toilet. Also, it is possible to use a water-soluble pressure-sensitive adhesive having moderate water-solubility or disintegration that causes cracks, or a pressure-sensitive adhesive composed of components that disintegrate in contact with water.

  As a material used for the water-soluble adhesive, for example, an adhesive such as polyvinyl acetate, starch, polyvinyl alcohol, and acrylic that can be appropriately dissolved in water can be used. For example, a water-soluble pressure-sensitive adhesive containing 100 to 100 parts by weight of polyvinyl alcohol having a saponification degree of 70 to 100%, 10 to 160 parts by weight of a water-soluble plasticizer selected from sugar, alkanolamine and polyether polyol, and 100 to 150 parts by weight of polyethyleneimine. Can be used. Also, for 100 parts of water-soluble base polymer (copolymer of methoxyethyl acrylate, caprolactone acrylate and sodium styrenesulfonate), 30 parts of water-soluble plasticizer (hexaol), surfactant (polyoxyethylene sorbitan fatty acid ester) A water-soluble or water-dispersible pressure-sensitive adhesive containing 1 part can also be used.

  An adhesive composed of components that disintegrate in contact with water is one that absorbs moisture and weakens the cohesive force of the adhesive and disintegrates, and has a styrene / isoprene / styrene copolymer as a hydrophobic component. Combined (SIS), polyisobutylene, hydrophilic component, Karaya gum, pectin, gelatin, polyester polyol, polyvinyl alcohol, other petroleum-based tackifiers as water-soluble polymers to enhance disintegration when discarded in water Etc. can be blended.

The ostomy pouch of the present invention is manufactured as follows.
1) A sheet that forms a bag and a flange are punched out from the underwater disintegrating sheet to create a sheet that becomes a flange.
2) Prepare a ring-shaped member to be a barrier member. The ring-shaped member is a ring made of a predetermined thermoplastic resin and having an outer diameter loosely fitted into the opening of the bag body and the flange and having a predetermined thickness.
3) Next, the sheet to constitute the bag and the sheet to be the flange are overlapped with the openings arranged concentrically with each other. At this time, the flange and the bag may be joined.
4) Next, the ring-shaped member is concentrically disposed so that the outer peripheral portion thereof is in contact with the inner peripheral surface of the opening portion of the sheet.
5) Next, when this ring-shaped member is hot-pressed, the ring-shaped member melts and covers and closely adheres to the inner peripheral surface of the opening. For this reason, the punched cross section of the underwater disintegrating substrate is covered with the barrier member. Alternatively, the flange member and the bag body may be joined simultaneously with melting the ring-shaped member in a predetermined shape.
6) When a hot press is not used, a sheet to form a bag and a sheet to be a flange are bonded in advance, and the sheet is attached to a mold, and the material of the barrier member is injected to the periphery of the opening. A so-called insert molding method that covers the cross section of the opening may also be used.
7) After that, when the sheet to constitute the bag is folded and heat-sealed to form a bag, an ostomy pouch is completed.

  Although the ostomy pouch of the present invention can be used as an inner bag for various ostomy appliances, a particularly preferred embodiment is that a flange of the inner bag is provided in a predetermined region on the radially inner side of the fitting portion for attaching and detaching the face plate and the outer bag. It clamps and fixes using the pressing force at the time of a fitting part fitting. For this reason, the face plate and the outer bag can be fixed using a pressing force when the inner bag is sandwiched between the inner and outer flanges of the fitting portion for attaching and detaching each other. It will have a structure that can be.

  For example, as shown in FIGS. 3 and 4 of Japanese Utility Model Publication No. 7-15542 by the applicant of the present invention, the flange of the inner bag is sandwiched and fixed inside the fitting portion of the face plate and the outer bag. The ring-shaped sealing piece 19 provided on the bag body shown in FIG. 5 and the ring-shaped taper portion 5 provided on the face plate, and also Japanese Patent Application No. 2005-120868 “Fitting device and excrement provided with the fitting device” The ring-shaped inner flange / ring-shaped seal protrusion and the ring-shaped seal portion shown in the specification and drawings of the “accommodating device” may be used. In the latter case, in order to securely fix the inner bag without increasing the size of the brace, the radial width of the pressing portion of the ring-shaped inner flange is 2.0 to 10 mm, preferably 3.0 to 6.0 mm. Good.

  The flange of the ostomy pouch serving as the inner bag has an outer diameter larger than the inner diameter of the ring-shaped inner flange and smaller than the outer diameter of the joint between the flange and the bag body, which is the substantial inner diameter of the flange. If present, the flange can be pressed against the face plate without causing unnecessary interference between the ring-shaped inner flange and the flange or bag. Further, since the fitting portion of the face plate is provided on the non-contact surface of the face plate and the portion protruding from the ring-shaped seal portion, the outer diameter of the flange is almost equal to or smaller than the inner diameter of the protruding portion. The flange does not cause unnecessary interference with the face plate.

  Moreover, as long as the inner bag, the face plate, and the outer bag satisfy the dimensional relationship, the form of the inner bag forms an opening on one surface of the bag body as in the present invention, and a barrier member on the inner periphery of the opening For example, the flange may be formed by flaring the opening of the bag body, or may be provided with a sheet-like flange around the opening using the end of the bag as an opening. Good.

  When the water-disintegrating base material constituting the flange of the inner bag and the bag body is water-disintegrating paper, the following convenience is obtained because the base material is stiff. That is, when the outer bag is removed from the face plate and the inner bag body is accommodated, the inner bag base material is loose, so the outer bag flange is sandwiched between the inner bag flange and the inner bag flange. Adheres to the surface of the flange of the outer bag. If the flange of the inner bag is slid along the surface of the flange of the outer bag in this state, the flange of the inner bag can be positioned concentrically with the flange of the outer bag. If the outer bag in which the flange of the inner bag is positioned concentrically is coupled to the face plate, the inner bag can be attached to the face plate at the same time.

  Since the inner bag is simply sandwiched between the outer bag and the face plate, when the connection between the face plate and the outer bag is released after use, the inner bag is detached from the face plate as it is. If the liquid excrement enters between the flange and the face plate during use, and the flange and face plate adhere due to the capillary force of the infiltrated excrement, remove a part of the inner bag from the outside of the outer bag. By gripping, the inner bag can be detached from the face plate. To take out the inner bag from the outer bag, it is possible to just pick the outside of the flange, or by bending the flange portion of the outer bag, the upper portion of the bag body of the inner bag may be protruded from the opening of the flange portion of the outer bag .

  The ostomy pouch of the present invention is not limited to the form in which the flange of the inner bag is sandwiched in the radially inner side of the fitting portion for attaching and detaching the face plate and the outer bag, and Japanese Patent Application No. 2006-7494 “Ostomy Pouch and its As shown in the description and drawings of “Manufacturing method and ostomy appliance”, a flange may be sandwiched between the fitting portions. Furthermore, it goes without saying that an ostomy pouch can be attached to and detached from the face plate by providing an adhesive layer as a water resistant layer of the flange and attaching and detaching the adhesive layer of the flange to the landing portion of the face plate.

Example 1
FIGS. 1 and 2 are processes for manufacturing an ostomy pouch according to the present invention, FIGS. 3 to 5 are processes for joining a flange and a bag and forming a barrier member using a hot press, FIG. 6 is a process for forming a barrier member by injection molding, and FIG. 7 shows the completed ostomy pouch.

The ostomy pouch of this invention is demonstrated along a manufacturing process. First, the entire manufacturing process will be described. Sheet 1 is a water-disintegrating paper made from Mishima Paper Co., Ltd. “Water-soluble paper” cultivar 30MDP, basis weight 30g / m ² , ethylene vinyl acetate copolymer (hereinafter referred to as “EVA”) as the main component and total weight of paraffin wax A water resistant layer obtained by die coating a hot melt composition containing 40% by weight of a coating to a thickness of 20 g / m ² is provided and punched into a shape to constitute a bag. Flange 2 is a water-disintegrating paper manufactured by Mishima Paper Co., Ltd. “Water-soluble paper” cultivar 120MDP, basis weight 120g / m ² , provided with a water-resistant layer of the same material and thickness as sheet 1 and punched into a predetermined ring shape It is.

  First, the sheet 1 and the flange 2 are joined to each other on a surface where a water-resistant layer is not formed by hot pressing or the like described later, and a barrier member is provided at the same time or after joining (FIG. 1A). Next, gussets 4 and 5 are formed by folding both the upper and lower sides in the longitudinal direction of the sheet 1 at a position corresponding to the inside of the flange 2 (FIG. 1B). The bent end portions 6a and 7a are further bent to oppose the end portions 6b and 7b (FIG. 2A). Since the water-resistant layer of the thermoplastic resin is provided on the opposed surfaces of the front end portions 6b and 7b, this surface is heat-sealed to make the sheet 1 cylindrical. Next, the left and right ends 8, 9 that are left open are heat-sealed to complete the bag body 10 having gussets on the top and bottom of the figure (FIG. 2 (b)). The completed ostomy pouch will be described later (FIG. 7).

  A method of joining the above-described sheet 1 and flange 2 using a hot press and providing a barrier member on the inner peripheral surface of the opening will be described. The molded sheet 25 serving as a barrier member is made of the same material as the water-resistant layers 17 and 19, has an outer diameter and an inner diameter that overlap with the edge of the opening, has a ring shape with a thicker inner periphery and a thinner outer periphery. It is a member. The flange 2, the molded sheet 25, and the sheet 1 are placed in this order on the mold cradle 14, and the upper mold 11 is disposed with the glass cloth PTFE sheet 13 laid (FIG. 3).

  When the heated upper mold 11 is lowered, the thick inner peripheral portion of the molded sheet 25 is crushed and spreads in the horizontal direction, covering the cross section of the water-soluble paper 18, 20 and contacting the openings of the water-resistant layers 17, 19 The entire inner peripheral surface of the opening is covered with the part. At the same time, the outer peripheral portion of the molded sheet 25 sandwiched between the water-soluble papers 18 and 20 joins both. The portion of the water-resistant layer 17 to which the heated upper mold 11 is in pressure contact is crushed and thinned, and an excessive bulge 21 may occur at the corner portion 12 of the upper mold 11, or breakage and pinholes may occur. The corner portion 12 of the upper mold 11 is preferably chamfered. If air is trapped in the upper mold 11, the molded sheet 25, and the sheet 1, a pinhole may be generated in the water-resistant layer 17 when the trapped air escapes, so the glass cloth PTFE sheet is laid as described above. Then, it is recommended that air be gently released along the irregularities on the surface of the glass cloth PTFE sheet (FIG. 4). When the hot press is completed, the barrier member 26 is covered along the edge of the opening 3 and is integrated with the water-resistant layers 17 and 19 and fixed to the water-soluble paper 18 and 20 (FIG. 5). The sheet 1 and the flange 2 may be bonded in advance with a hot melt adhesive or the like, and hot pressing may be performed using a molded sheet having an outer diameter substantially equal to the diameter of the opening.

  The barrier member can also be provided by an insert molding method. FIG. 6 shows a subassembly 31 in which the sheet 1 and the flange 2 are joined. The insert molding die includes a cylindrical upper die 33 and a ring-like lower die 34 fitted concentrically with the lower portion of the upper die 33. Nozzle holes 36 for injecting molten resin are arranged at equal intervals on the inner peripheral surface of the upper mold 33. The sheet 1 and the flange 2 are bonded in advance with a hot-melt adhesive or the like as indicated by a joint portion 32 to form a subassembly 31. When the flange 2 side of the subassembly 31 is placed in the recess 34 a of the lower mold 34 and then the upper mold 33 is lowered, the cavity 35 is formed by the upper mold 33, the lower mold 34, and the subassembly 31. . In this state, a molten thermoplastic resin is injected from the nozzle hole 36 into the cavity 35 to cover the cross section of the opening integrally with the subassembly 31.

  In the ostomy pouch completed by the manufacturing process described above, the flange 2 protrudes from the bag body 10 in the short side direction of the bag body 10, and the bag body 10 protrudes from the outer periphery of the flange 2 in the long side direction (FIG. 7 ( a)). According to a sectional view through the opening 3 (FIG. 7 (b)) and a view from the top (FIG. 7 (c)), the back of the bag 10 is in the vicinity of the opening by the gussets 4 and 5 when the bag 10 is inflated. It can be easily guessed that the depth up to 10a is increased compared to the depth without gussets 4,5.

(Example 2)
FIG. 8 shows the face plate (FIG. 8 (a)) and outer bag (FIG. 8 (b)) of the ostomy appliance of the present invention, and FIG. 9 shows the face plate (FIG. 9 (a)) and outer bag. When the ostomy pouch is accommodated (FIG. 9B), FIG. 10 is a view showing a state where the inner bag and the outer bag are attached to the face plate. 9 and 10, the outer bag is illustrated with a dotted line so that it can be easily distinguished from the inner bag. For the face plate and outer bag used in Example 2, the specification and drawings of Japanese Patent Application No. 2005-120868 can be referred to.

  First, the entire ostomy appliance according to the present invention will be described in accordance with a procedure for attaching and detaching. The face plate 41 has a ring shape called a so-called floating flange in which a skin protective material 43 is laminated on the skin-contacting side of the substrate 42 and is fixed around the opening 44 on the non-skin-contacting side of the substrate 42 and the outer peripheral portion is lifted. A seal portion 45 is provided, and a common opening 44 is formed in the skin protection material 43, the substrate 42, and the ring-shaped seal portion 45. On the outer periphery of the upper surface 46 of the ring-shaped seal portion 45, a ring-shaped protrusion 47 having a fitting portion for coupling with the outer bag 51 is provided. The outer bag 51 includes an opening portion 56 for receiving excrement, a ring-shaped flange 52 in which a fitting portion for coupling with the face plate 41 is formed, and a bag body 53. The flange 52 is provided with a ring-shaped inner flange 54 that extends radially inward and toward the face plate from the fitting portion. The inner bag 61 includes a flange 62 and a bag body 63. Only the upper portion of the bag body 63 shows two upper end portions 68 and 69 according to the gusset, but the lower end is the same.

  In order to attach the ostomy pouch of Example 1 to the face plate 41, first, the ostomy pouch of Example 1 is attached as an inner bag to the outer bag. The bag body 63 of the inner bag 61 is inserted through the opening 56 of the outer bag 51 only from the portion below the flange 62. Next, the upper portions 68 and 69 from the flange 62 of the bag body 63 of the inner bag 61 are bent and placed inside the bag body 53 of the outer bag 51. At this time, the outer bag 51 and the inner bag 61 have a double structure as a whole, and the inner bag 61 has an appropriate hardness in the water 62 that is the base material of the flange 62 and the bag body 63. It closely contacts the ring-shaped inner flange 45 of the outer bag 51. Since the flange 62 of the inner bag 61 is in the form of a sheet with a flat contact surface, it can be slid and aligned with the ring-shaped inner flange 54 of the outer bag 51 in a concentric manner.

  Since the outer diameter of the flange 62 of the inner bag 61 is set smaller than the inner diameter of the ring-shaped protrusion 47 of the face plate 41, the fitting portion provided on the flange 52 of the outer bag 51 is used as the ring-shaped protrusion 47 of the face plate 41. By combining with the fitting portion provided in the inner plate 61, the face plate 41 and the outer bag 51 are combined, and the flange 62 of the inner bag 61 is sandwiched and fixed between the ring-shaped inner flange 54 and the ring-shaped seal portion 45. The face plate 41 and the inner bag 61 are combined.

  After use, the coupling between the face plate 41 and the outer bag 51 is released, and the inner bag 61 and the outer bag 51 are removed from the face plate 41 while being integrated. It is bent so that the flange 62 of the outer bag 51 protrudes from the opening of the flange 52 by sandwiching two places in the direction perpendicular to the paper surface of the flange 52 of the outer bag 51 with a thumb and an index finger. While holding this state while holding both sides of the flange 52 of the outer bag 51, the upper part of the bag body 63 of the inner bag 61 is pushed from the back to protrude from the opening 56 of the outer bag 51. The upper end of the protruding bag body 63 is pinched and taken out from the outer bag 51, and the inner bag 61 is dumped into a flush toilet. Clean the face plate 41 and attach a new inner bag together with the outer bag as described above.

Details of the connecting portion will be described.
FIG. 11 shows the details of the connecting portion in a state where the inner bag is attached to the outer bag and before being attached to the face plate, and FIG. 12 shows the details of the connecting portion where the outer bag and the inner bag are attached to the face plate. For the sake of explanation, FIGS. 11 and 12 are shown with the axial direction enlarged compared to the radial direction.

According to FIG. 11, the face plate 41 is provided with a pair of protrusions for fitting to the ring-shaped protrusion 47, and the ring-shaped seal portion 45 has a ring-shaped inner peripheral portion near the opening 44. A concave portion 48 and a convex portion 49 are formed by pressing when the seal portion 45 is heat-sealed to the substrate 42 (FIG. 11A).
The flange 52 of the outer bag 51 is provided with a pair of recesses for fitting, a ring-shaped inner flange 54 extends radially inward from the fitting portion, and the tip 55 has a thick protruding cross section. (FIG. 11B). The ring-shaped inner flange 54 has a radial width (W1) of 4.1 mm along the surface that presses the ring-shaped seal portion, a width (W2) from the fitting portion to the tip portion 55 of 3.0 mm, and an inner diameter. Is 60 mm (FIG. 11C).
The flange 62 of the inner bag 61 has an outer diameter of 70 mm, and the outer diameter of the joint with the bag body 63 is 54 mm. When the inner bag 61 is attached to the outer bag 51, the center portion of the flange 62 is somewhat drawn into the outer bag, but the ring-shaped inner flange 54 and the tip 55 thereof are the flange of the inner bag 61. 62 and the wedge 63 between the bag 63 and the flange 62 comes into close contact with the ring-shaped inner flange 54 to perform the above-described alignment.

  According to FIG. 12, the convex portion of the flange 45 fits into the concave portion of the flange 52, and at this time, the ring-shaped inner flange 54 and its tip 55 press the flange 62 toward the ring-shaped seal portion 45. The inner bag 61 is coupled to the face plate 41. Since the distal end portion 55 is molded to be thick, the flange 62 can be firmly sandwiched without being rolled up by pressing. Further, since the convex portion 49 exists in the ring-shaped seal portion 45, the convex portion 49 is pressed against the flange 62 and is sealed at the pressing portion, whereby the liquid excreta is connected to the flange 62 and the convex portion 49. It is possible to block leaching from the contact portion to the outer peripheral side.
