Description of the invention (1) Brief description of the invention The present invention relates to disposable diapers that can be rolled up and discarded after use. ---------- itch ------ 1T .f (please read the precautions on the back and then write down this page) The previous technology is published in Japanese Shikai Ping 5 _ 5 1 3 2 7 bulletin It describes the use of disposable diapers in the underpants after use, tearing the opening edge of the waist with elastic members in the direction of the waist to make a stretchable ring body, and using this ring_body to roll up the used diapers and discard them. . The method of discarding diapers in this way does not expose parts dirty with excrement, so it is good in terms of hygiene and aesthetics. In Shikaihei 5-3 3 9 5 3 1 of Japan, it is stated that an adhesive tape is prepared on the back sheet of a diaper, and this tape is used to roll up the diaper and the problem to be solved by the invention. The use of adhesive tape to roll up the used diapers has the advantage of simplicity, but if the adhesive surface of the tape is stained, it will lose its adhesion and completely lose its function. The method of rolling up the used diaper into a ring-shaped body as disclosed in the publication No. 5-5 1 3 2 7 is true, so that the method of rolling up the diaper does not have such a disadvantage, but when removing the dirty diaper, if If the left and right sides of the diaper are torn open, there is a problem that this method cannot be used. If you defecate when wearing underwear-type diapers, tear the left and right sides of the diaper and take off the diaper. At this time, the paper size is not applicable to the Chinese National Standard (€) 84 specifications (210 to 297 mm) -4- A7 ____B7_ printed by the employee consumer cooperative of the Central Bureau of Standards of the Ministry of Economic Affairs 5. Description of the invention (2) It can be made into the aforementioned ring-shaped body without rolling up the diaper, so it is not good. Here, the subject of the present invention is to roll up the diaper even if the left and right sides of the pant-type diaper are torn. Means for Solving the Problems In order to solve the aforementioned problems, the present invention was previously titled as follows: the liquid-absorbent chip is interposed between the liquid-permeable top sheet and the liquid-impermeable back sheet, and the left and right side edges of the front waist region and the back waist region are respectively They are joined together to form a pant-type disposable diaper with a waist opening and a pair of leg openings. With regard to the relevant premise, the present invention is characterized in that the back sheet has a designated portion in any of the upper and lower directions of the front and rear waist regions, and has a full width across the left and right directions of the region toward the outside of the diaper. A wrinkle of the wrinkle, the inner surface of the wrinkle is provided with at least one stretchable elastic member along the circumference of the waist, and the upper and lower base ends of the wrinkle extend toward the aforementioned waist circumference to apply a stitch, and the wrinkle The left and right ends of the fold are overlapped and fixed to any of the left and right edges of the waist area. EXAMPLES With reference to the attached drawings, the pant-type disposable diapers related to the present invention will be described in detail as follows. The pant-type disposable diaper 1 shown in the partially cut perspective view shown in Figure 1 is seen from the rear side. The diaper 1 is composed of a liquid-permeable surface sheet 2, a liquid-impermeable back sheet 3, and a liquid-absorbent chip 4 interposed between the two sheets 2'3, and has a front waist region 6 and a rear amine The enclosed area 7 and the area around the two waists are in accordance with the Chinese National Standard (CNS) Λ4 specifications (210X297mm) _ 5 (Please read the precautions on the back before writing this page privately) Binding · Stranding A7 B7 5. Description of the invention (3)-Please first note the notes on the back of the cabinet ik 4, then I install the crotch area 8 between pages 6 and 7. The front and back sheets 2 and 3 are joined to each other at a portion extending from the periphery of the chip. The front and rear waist regions 6 and 7 have their respective side edges ^ A and 7 A, which extend toward the outside of the diaper i and overlap with the surface film 2 as the inside, and are joined intermittently in the fusion region 9 arranged vertically in the diaper Instead, the waist opening 11 and the pair of left and right leg openings 12 are defined. A waist elastic member 13 and a leg elastic member 14 are arranged on the peripheral portions of the openings 1 1 and 12. These elastic members 1 3 and 14 are joined to any of the front and back sheets 2 and 3 in an extended state. Inside. -'The front and rear waist regions 6, 7 of the diaper 1 are provided with a plurality of elastic members 16 extending in parallel to the waist direction and arranged at a certain interval in the up and down direction. This elastic member 16 is interposed between the back sheet 3 and the chip 4 and is bonded to the inner surface of the back sheet 3 in an extended state. However, the portion of the elastic member 16 extending laterally from the side edge of the chip is located between the front and back sheets 2, 3. Printed by the Beigong Consumer Cooperative of the Central Bureau of Standards of the Ministry of Economic Affairs 11 The rear waistline area 7 is near the center in the up and down direction, and the back sheet 3 is bent toward the outside of the entire diaper 1 of its banner, forming a wrinkle with a U-shaped cross section 1 7. The wrinkle 17 has the top and bottom of the wrinkle at the right and left ends 18 overlapped on the outer surface of the side edge portion 7 A of the back waistline region 7 and is fixed by the fusion area. Not easy to peel. The upper and lower base end portions 21A, 21B of the wrinkle 17 (refer to Fig. 2 to be described later) extend from the back sheet 3 toward the waistline with slits 22A, 22B that are intermittently cut away. In addition, the cutouts 22A and 22B may extend to the wrinkled side end portion 18, or may not extend to this place. In addition, the size of this paper is in accordance with Chinese National Standard (cns) a4 (2 mm 297 mm) -6-V. Description of the invention (4), the length of each cut 2 2A, 2 2B arranged in the direction of the body circumference is When the length of the portion between the cuts is large, it is preferable in the tearing operation. In addition, if the back sheet 3 is made of fiber nonwoven fabric or contains fiber nonwoven fabric, it is preferable that these slits are crossed in the direction of the fiber to determine the direction when tearing off. Fig. 2 is a π-ll line cross-sectional view of Fig. 1, showing a cross section of wrinkle 17; The back sheet 3 is almost U-shaped in the lateral direction and is formed by a fold 17 that is bent. The inner surface near the top 19 has at least one elastic member 26 extending in the waist direction and joined in an extended state, overlapping each other. The inner surfaces of the are joined by a hot-melt adhesive (not shown in the figure). The wrinkle 17 thus formed can be torn away from the outside of the back waistline region 7 at the cutouts 22A, 22B except for the left and right end portions 18. In FIG. 2, the left and right end portions 18 of the torn crease 17 are fixed to the back waist region 7 and form a ring together with this region 7. The relevant wrinkle 17 can be torn off after the front and back of the fusion zone 9 on the left and right sides of the diaper 1 after wearing, and the wrinkle 17 can also form a ring together with the area around the rear body 7 》 The third figure printed by the Employee Consumer Cooperative of the Central Bureau of Standards of the Ministry of Economic Affairs is a perspective view of a user rolling up a diaper 1 using a wrinkle 17. The dirty diaper 1 can be pulled down and taken off, or the left and right sides can be torn off and taken off. The wrinkle 17 is torn off by the area around the body during the taking off process. Next, the wrinkle 17 is positioned on the outside, the diaper 1 is rolled up, and the wrinkle is folded in the illustrated state. The wrinkle 17 is elastic due to the presence of the elastic member 26, so that the rolled up diaper can be unfolded and the diaper can be easily bundled. This elastic member 26 can be used in conjunction with the paper standard of the front and back of the paper. It uses the Chinese National Standard (CNS) A4 specification (210X297 mm) -7-A7 B7 317493 V. Description of the invention (5) Please read the SJ I matters first The elastic member 16 in the waist area 6 '7 is the same as that of this page. In addition, it can also be an elastic member with a different elasticity. The wrinkle 17 may be located in any of the front and rear waist regions 6, 7 and if it is provided in the back waist region 7, the hands of the infant wearing the diaper 1 are not easily constructed, which is preferable. In the diaper 1 related to this invention, conventional materials can be used for the front and back sheets 2, 3 or the chip 4, and these materials can be joined with adhesives such as hot-melt adhesives. If these materials also have hot-melt properties, by melting The welding area 9 illustrated in the figure is an example of the latter bonding. These fixing techniques can also be used when fixing the side end portion 18 of the wrinkle 17. Effects of the Invention The underpants-type disposable diaper related to the present invention has the left and right ends at any one of the front and rear waist regions, and has the flexibility to cut these side ends from there. The diaper is folded, so when removing the diaper, even if the left and right sides have been torn open, the diaper can be rolled up and discarded.
