No. 60-7709, Japanese Unexamined Patent Publication No. 56-91002, etc., in order to ensure good attachment to the crotch part during use and to secure the dimensions of the end flap on the diaper body, It is constructed by trim cutting with recesses on both sides of the center part, but not only is the material of the trim cut part wasted, but the end flap part does not need to be made of the same material as the diaper. However, they use the same expensive materials as diapers, making the product expensive.

Reference numeral 1 denotes a leak-proof layer, which is formed of a water-impermeable resin film such as a polyethylene film. On the surface of the leak-proof layer 1, An absorbent body 2 formed narrower than the leakage prevention layer 1 is positioned. The structure of this absorbent body 2 is not particularly limited as long as it can absorb and retain urine etc. excreted from the human body.
In this embodiment, an absorbent paper 3 is placed on the inner surface of the leak-proof layer 1, and a relatively thick cotton pulp layer 4 is placed on the inner surface of the absorbent body 3. The polymer absorbent sheet 5 is placed in a sandwich pattern. Then, the surface of the absorbent body 2 is covered with a water-permeable surface layer 6 formed of a nonwoven fabric made of polyolefin fibers, etc., and the surface layer 6 and the leak-proof layer 1 are heated at least at both sides of the absorbent body 2. Attach by welding, adhesive, etc. When the surface layer 6 and the leak-proof layer 1 have the same length in the width direction and the longitudinal direction, the adhesion between the surface layer 6 and the leak-proof layer 1 is determined not only at both sides of the absorbent body 2 but also at the longitudinal direction. In this case, the surface layer 6 and the leak-proof layer 1 are bonded together, but in order to save on the surface layer 6, which is a relatively expensive material, the width of the surface layer 6 is made to be approximately the same as that of the leak-proof layer 1, and the length is When the direction is substantially the same as that of the absorbent body 2, the leak-proof layer 1 and the surface layer 6 are bonded only at positions on both sides of the absorbent body 2.

面積に形成している。 Then, the above surface layer 6, leak prevention layer 1, absorber 2
A diaper main body 7 is formed. Since there is no need to consider the end flap part of this diaper body 7, it is formed to be narrow enough to be worn between the crotch.
It is possible to reduce the amount of materials used compared to conventional products. Further, an end flap 8 formed separately from the diaper body 7 is fixed to the longitudinal end of the diaper body 7 on the surface layer 6 side. As shown in FIGS. 2 and 4, this end flap 8 is made of a resin laminate 10 such as foamed urethane resin, urethane film, polyethylene film, etc., and a nonwoven fabric 1.
The material sheet 12 is laminated on the surface of the diaper 1 to have stretchability and elasticity, and the material sheet 12 is punched and molded separately from the manufacturing process of the diaper body 7. The end flap 8 formed by punching and molding is fixed to the side corresponding to the back part in the longitudinal direction of the diaper main body 7, but the end flap 8 is fixed to the longitudinal direction of the diaper main body 7 on the opposite side from the fixing part of the end flap 8. As shown in FIG. 2, the covering flap 13 is integrally punched and formed from the same material sheet 12. Both sides of the end flap 8 protrude outward from the width direction of the diaper main body 7 to form protruding pieces 14, and the fixing portion of the end flap 8 is attached to the inner surface of the protruding piece 14 when worn on the human body. A fastening portion 15 is formed for fastening to the outer surface of the opposite ventral side. The attachment portion 15 is formed by applying an adhesive such as hot melt to the protruding piece 14, and by attaching release paper or the like to the diaper main body 7 side of this coating type, a release layer is formed. 16
is formed, and before the start of fastening use, the fastening part 15 of the protruding piece 14 is bent toward the mold release layer 16 to temporarily fasten the fastening part 15 to the mold release layer 16. Further, the covering flap 13 is formed to have approximately the same width as the diaper main body 7, and is formed in an area that covers a part of the longitudinal direction of the absorbent body 2 while being fixed to the end of the surface layer 6 of the diaper main body 7. are doing.

る。 In order to fix the diaper main body 7 and end flaps 8, which are formed in separate processes, as shown in FIG. This is done by placing the end flap 8, but the results are somewhat different depending on whether only the end flap 8 is fixed to the diaper main body 7 or when the end flap 8 with the covering flap 13 integrally attached is fixed. To connect the end flap 8 integrally provided with the covering flap 13 and the diaper main body 7, the diaper main body 7 is continuously fed in a connected state as shown in FIG. 17, a covering flap 13 is placed on one diaper main body 7 to be connected, and an end flap 8 is placed on the other diaper main body 7, and each covers a little of the longitudinal surface of each absorbent body 2. In this state, heat weld the
It is fixed to the diaper main body 7 using adhesive or the like to prevent leakage from the longitudinal direction of the absorbent body 2. In the next step, the covering flap 13 and end flap 8 are cut from the connecting portion 17. By repeating this process, the end flap 8 is fixed to one side of the diaper body 7 in the longitudinal direction.
A covering flap 13 is fixed to the other longitudinal end. In this state, the surface layer 6 that covers the surface of the absorbent body 2 can have approximately the same longitudinal dimension as the absorbent body 2, which saves the amount of expensive material used for the surface layer 6. becomes possible.

いる。 Further, the covering flap 13 is not necessarily an essential requirement, and in different embodiments, only the end flap 8 may be fixed to the diaper body 7. Further, on the leak-proof layer 1 side of the diaper main body 7, an adhered film 18 formed of polypropylene film or the like is provided to releasably fasten the fastening part 15.
It is fixed on the side opposite to the fixed part of the end flap 8.

製品を得ることができるものである。Effects of the Invention Since the present invention is configured as described above, by forming the end flaps provided at the longitudinal ends of the diaper separately from the diaper body, there is no need to be limited by the shape, size, material, etc. of the diaper. This makes it possible to arbitrarily decide according to the purpose of use. Therefore, for example, if the end flap is laminated with a moisture-impermeable resin, leakage from the longitudinal surface layer can be prevented, and a hydrophilic surface material that easily absorbs sweat, such as rayon fiber, which is different from the surface layer, can be used. For the surface layer, it is possible to use a material such as polyolefin fiber, which has good wet bag performance. In addition, since the diaper body can be formed without considering the required dimensions of the end flaps, the dimensions of the diaper body can be limited to the width necessary only for the disposal of excrement, and there is no need to trim and cut both sides of the diaper body, and the end flap portion Since there is no need to consider dimensions, it is possible to reduce the amount of moisture-permeable surface layer, which is an expensive material, which reduces the amount of material used in diapers compared to conventional products, resulting in a cheaper product. It is something that can be done.
