Yes. At least the stool flight receiving hole 31 in the bottomed flight receiving hole 30 is formed in a shape and size that can be accommodated in the defecation tube portion of the diaper cover in the base invention.

  Gathers 14 and 15 are provided in a portion 12 where the diaper body fabric 10 hits the waist of the living body and a portion 13 where both feet of the living body come out from the diaper body fabric 10, respectively. Frills 16 for preventing stool leakage are provided at the edges of the two vertical sides of the diaper body fabric 10. The cover fabric 20 has a substantially square planar shape, and elongated protrusions 21 protrude outward from the upper and lower portions of the outer edge. One planar fastener 22 is provided on the inner wall surface of the projecting piece 21. The other planar fastener (for example, pile ground) 17 corresponding to the planar fastener 22 is provided in a wide range outside the portion located in the abdomen when the diaper main body fabric 10 is attached to the living body.

  On both sides of the connecting line 33 in the diaper main body fabric 10, urine leakage prevention walls 18 that substantially match the dimensions from the end of the stool receiving hole 31 to the end of the stool receiving hole 32 are erected. Yes.

  The diaper configured as described above can be manufactured as follows. A raw fabric 10A for the diaper body fabric 10 is prepared. As shown in FIG. 4, the raw fabric 10 </ b> A has a square planar shape, and its configuration is as shown in FIG. 5. That is, the waterproof sheet 40 is disposed outside the diaper. The waterproof sheet 40 is a sheet in which an outer skin 41 made of mesh-like paper or the like and a waterproof resin sheet 42 such as vinyl disposed inside the outer skin 41 are bonded and integrated. It becomes a cover for diapers and traps moisture inside.

  The surface of the diaper that touches the skin of the living body can be constituted by, for example, a surface sheet 43 that permeates water and confines it inside. An extremely thin waterproof resin sheet 44 is disposed on the surface in contact with the waterproof sheet 40. Between the surface sheet 43 and the resin sheet 44, a cover sheet 45, a water adsorbing member 46, and a wrapping sheet 47 are arranged from the surface sheet 43 side.

  The cover sheet 45 is a sheet that allows water to pass therethrough, and is more preferably a sheet that allows water to pass through and is confined inside. The water adsorbing member 46 can be made of an absorbent material including cotton-like or sponge-like paper or cloth. The wrapping sheet 47 can be configured by a sheet similar to the cover sheet 45.

  The wrapping sheet 47 includes a bottom surface 47A and a folding margin 47B that protrudes from two opposite sides of the bottom surface 47A and is bent inward from the upper side. The water adsorbing member 46 is placed on the bottom surface 47A of the wrapping sheet 47, the cover sheet 45 is overlaid thereon, and the core body 48 is assembled such that the water adsorbing member 46 and the cover sheet 45 are wrapped by the margin 47B. The assembled core body 48 has a planar shape that fits within the broken lines shown in the top sheet 43 and the resin sheet 44, and the core body 48 is sandwiched between the top sheet 43 and the resin sheet 44. The portion on the edge side from the broken line is fixed by heat welding or the like. The multiple sheet 49, which is the main body of the diaper produced by this fixing, is overlaid with the waterproof sheet 40 and, for example, is suitably bonded at the edge side from the broken line of the top sheet 43 and the resin sheet 44. In addition, each member which comprises the multiplex sheet | seat 49 is only an example, and arrangement | positioning and the number to use of a waterproof sheet | seat, a water adsorption sheet | seat (material), etc. are changed suitably. Alternatively, a superabsorbent polymer, a superabsorbent resin, or the like may be disposed at any part of the multiple sheet 49 to confine moisture excrement such as urine in the multiple sheet 49.

  The size of the raw fabric 10A having the above configuration can be, for example, 900 mm × 600 mm in length × width. This raw fabric 10A is folded in half along the center line c in FIG. 4, the pattern 2 shown in FIG. 6 is applied to the raw fabric 10A, and a connecting line L is drawn at the connecting portion. The pattern 2 is formed with convex portions 3 corresponding to the diaper-bottomed stool receiving hole 30 in a predetermined width, a predetermined height, and a predetermined shape, so that a necessary and sufficient bottomed stool receiving hole 30 can be obtained. . Since the connecting line L is a sewn line for sewing with a sewing machine or a line segment showing a connecting part for heat welding, it is not necessary to actually draw the connecting line L, and it is sufficient if the connecting process can be performed.

  In the present embodiment, the coupling is performed using a sewing machine, and sewing is performed along the coupling line L by a lock sewing machine or an edge sewing machine. In this case, some lock sewing machines have a cut-and-sew function for sewing with the excess portion as a clerk, so there is no need to cut along the connecting line L in this sewing machine. Cutting is performed along the connecting line L. In addition, when performing the coupling | bonding by an adhesive agent or heat welding, it is necessary to cut along the coupling line L. FIG.

  FIG. 7 shows a state in which the inner side is opened after the coupling is performed as described above. In this case, a bottomed stool receiving hole 30 is completed. In this embodiment, a stool stool receiving hole 31 and a stool stool receiving hole 32 are formed. Next, weaving the positions of the ½ dimension from the connecting line 33 to the left side and the right side along the broken line b, stitching the position d to a predetermined depth from the top of the mountain as shown in FIG. A leakage prevention wall 18 is formed. As described above, the urine leakage prevention wall 18 has a length substantially matching the dimension from the end of the stool receiving hole 31 to the end of the stool receiving hole 32 on both sides of the connecting line 33. It is formed. The urine leakage prevention wall 18 may be formed by bending the entire raw fabric 10A as described above, and sewing the multiple sheet 49 except the waterproof sheet 40 and sewing the multiple sheet 49. Also good. Further, the urine leakage prevention wall 18 may be configured by attaching a nonwoven fabric or the like having gathered wrinkles to the multiple sheet 49 by heat welding or the like on the portion where the urine leakage prevention wall 18 is formed in the multiplex sheet 49. In addition, a non-woven fabric or the like that is bent to form a crease is provided on the surface of the multiple sheet 49, and the crease is formed into a gather form using this to attach the base to the multiple sheet 49 side by heat welding. Thus, the urine leakage prevention wall 18 may be configured.

  Next, two cover cloths 20 having a concave shape in plan view as shown in FIG. 9 are prepared for left and right. The cover fabric 20 can be configured by attaching a nonwoven fabric to the waterproof sheet 40 shown in FIG. Of course, the same structure as the diaper main body fabric 10 can also be adopted. A double-sided tape 24 for adhering to the surface of the outer skin 41 of the waterproof sheet 40 of the diaper main body fabric 10 is attached to the inner vertical edge, and the cover fabric 20 is attached to the diaper main body fabric 10. In the cover fabric 20, the length of the inner vertical side to which the double-sided tape 24 is attached is about 1/3 to 2/5 of the vertical length of the diaper main body fabric 10. As appropriate. One planar fastener 22 is provided on the inner wall surface of the protruding piece 21.

  The gathers 14 and 15 can be created using the gathering component 50 shown in FIG. A tape 51 in which an adhesive material is applied to one surface of the nonwoven fabric corresponding to the length of the gathered portion before shrinkage shown in FIG. 10 (a), and a rubber string 52 corresponding to the length of the gathered portion after shrinkage. (FIG. 10B) constitutes a gather component 50. As shown in FIG. 10C, the rubber string 52 is extended so as to match the length of the tape 51, and the rubber string 52 in the extended state is attached to the adhesive material surface 51 </ b> A of the tape 51. The gathered component 50 in the stretched state is attached to positions (ranges) P1 and P2 to be gathers 14 and 15 in the diaper main body fabric 10 (FIG. 11). When the hand is released after the sticking, the rubber string 52 contracts and the gathers 14 and 15 are created. This gathering manufacturing method is only an example, and various methods such as sewing with a sewing machine with a stretchable member such as rubber stretched on the pasting part, or pasting with an adhesive or heat welding, etc. Can be adopted.

  The frill 16 is attached to the required position. The portion of the position P2 is a straight line, but this portion can be cut out in an arc shape toward the inside to form a shape that fits appropriately along the thigh portion. Furthermore, in the diaper main body fabric 10, the other planar fastener 17 (for example, a pile ground) corresponding to the planar fastener 22 is provided on the surface side of a wide region covering the abdomen when the diaper is mounted. With this configuration, the waist size can be adjusted by the planar fasteners 17 and 22.

  In the above configuration, the diaper main body fabric 10 is configured by the multiple sheet 49 and the waterproof sheet 40. However, as shown in FIG. 12, the bubble cushioning material sheet 60 is interposed between the multiple sheet 49 and the waterproof sheet 40. Also good. In this case, the bubble cushioning material sheet 60 is also provided with holes 61 and 62 (bubbles inside the hole) corresponding to the stool receiving hole 31 and the stool receiving hole 32. Further, it is expected that the softness can be controlled by reducing the size of the bubbles in the bubble cushioning material sheet 60 or adjusting the amount of air in the bubbles, thereby giving a comfortable wearing feeling.

  In the first embodiment, the stool receiving hole 31 and the urine receiving hole 32 are provided in the bottomed stool receiving hole 30 to prevent the stool from being mixed with the stool, and the sacrum and the pubic part. However, as shown in FIGS. 13 and 14, only the feces receiving hole 31 may be provided in the bottomed feces receiving hole 30. In the case of this configuration, there is no hole for receiving urine, but the stool receiving hole 31 is sufficiently deep (for example, 80 mm or more) and the volume is increased to prevent urine from being mixed with the stool. Since the sacrum and pubic area can be kept clean, it can be expected to prevent the development of cystitis. The diaper according to the second embodiment can also be manufactured in the same manner as the first embodiment.
