DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a disposable diaper having a post-treatment bag, and more particularly to a post-treatment post-treatment diaper which is easy and more hygienic.

[0002]

2. Description of the Related Art There are widely used disposable diapers of the complete pants type and the tape type. This complete pants type is made in advance in a pants shape as shown in FIG. 9, and when worn, it is worn through both feet like pants. The tape fastening type has a developed shape as shown in FIG. 10, which is cut off along the side flaps (8) on both sides of the complete pants type, and covers the crotch of the human body forward and backward when worn. Is attached to the other end of the fastening tape (9) attached to the other end to be used as a pants shape. The cross-sectional structure of such a disposable diaper has an inner surface covered with a surface nonwoven fabric (11) with an absorber (10) interposed therebetween as shown in FIGS. 13 (a) and (b), and an outer surface with an impermeable liquid such as polyethylene. The backsheet (12) is covered with a nonwoven fabric (13), and the backsheet (12) is further laminated with an exterior nonwoven fabric (13).

[0003] For example, after the use of a complete pants type disposable diaper, the disposable diaper is treated as follows and then discarded. That is, as shown in FIG. 9, a folding adhesive tape (14) is attached in advance to the upper end of the paper diaper on the ventral side, and after use, it is wound from the crotch portion and the adhesive tape (14) is turned into a bar shape as shown in FIG. As shown in FIG. 12, the adhesive tape (14) is drawn out, extended, and adhered, thereby discarding the filth while being wound up inside.

By the way, in such a processing method, since only a part of the wound diaper is stopped, it is not possible to completely contaminate the dirt, and there is a concern that the waste may protrude from the side or generate an odor. In addition, depending on the movement of the wearer during wearing, there is a possibility that the attached adhesive tape comes into contact with furniture, bedding, or the like, and comes off or is damaged. In particular, in the case of a baby, the corners of the attached adhesive tape (2) may be in contact with the skin.

SUMMARY OF THE INVENTION The present invention has been made in view of the foregoing, and as a result, it has been possible to provide a disposable diaper with a post-treatment bag which can completely contain the dirt in the disposable diaper after use.

That is, the present invention relates to a disposable diaper in which an absorbent is interposed between an inner surface nonwoven fabric and an outer liquid-impermeable backsheet, or a disposable diaper having an outer nonwoven fabric further provided on the outer surface of the backsheet. A bag is formed on the outermost surface of the disposable diaper, and the disposable diaper wound so that the bag is turned upside down is covered with the bag by turning over the bag. It is a paper diaper with a post-processing bag, at this time, one of the opposite sides of the rectangular sheet as a bag is folded back to single or double, respectively, and the leading edges of the folded portions abut, close or overlap,
It is preferable that a line for fixing the folded portion and the non-folded portion is provided along the edge of the other opposing side.

Further, in the method for producing a disposable diaper according to the present invention, the long sheet member is supplied in the longitudinal direction, and both side edges thereof are continuously folded in a single or double manner, and the leading edges of the folded portions are brought into contact with each other and come close to each other. Alternatively, after overlapping, the folded portion and the non-folded portion are fixed in a band shape in the width direction at a predetermined interval in the longitudinal direction, and then cut along the band-shaped fixing line to obtain a bag body. Is fixed to the outermost surface of the disposable diaper.

[0008]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS As shown in FIG. 1, a long sheet member (1) made of nonwoven fabric or polyethylene is supplied in the longitudinal direction, and both side edges of the long sheet member (1) are continuously connected as shown in FIG. First, it is folded back once and then again as shown in FIG. 3 to form double folded portions (2) and (2) continuously, and the leading edges of the folded portions (2) and (2) are brought close to each other. Was. Then, as shown in FIG. 4, the folded portions (2) and (2) and the non-folded portion (3) are fixed in the width direction by heat fusion at predetermined intervals, and then cut along the fixing line (4). As a result, a bag (6) having an opening (5) between the leading edges of the folded portions (2) and (2) was produced.

The outer surface of the non-folded portion (3) of the bag (6) is fixed to the outermost surface of a tape-type disposable diaper or a complete pants-type disposable diaper by hot melt or the like, thereby obtaining a structure shown in FIGS. A paper diaper with such a post-processing bag was manufactured. In this example, such a bag was fixed to the outer surface of the disposable diaper in the final step of the disposable diaper manufacturing,
It may be fixed at any earlier manufacturing stage. Further, in this embodiment, the opening (5) is a case where the leading edges of the folded portions (2) and (2) are close to each other. This also includes the case of superimposition.

According to the disposable diaper with a post-treatment bag as shown in FIGS. 5 and 6, the diaper is folded inside after use, and the disposable diaper is wound so that the filth portion is inside, so as to form a rod as shown in FIG. . Then, by opening the opening (5) to both sides and turning the bag (6) upside down, the rolled-up diaper can be completely covered by the bag (6) turned upside down.

The fixing position of such a post-processing bag is not limited to the position shown in FIGS. 5 and 6, and may be a crotch position of a disposable diaper. Although the opening (5) of the bag body is fixed in the vertical direction in FIGS. 5 and 6, the bag body may be fixed in the horizontal direction. Further, such a bag body may be a general bag member (7) as shown in FIG. In addition, as the material of the bag body, a polyethylene sheet or a non-woven polyethylene laminated paper can be used in addition to the above-mentioned non-woven fabric.

[0012]

According to the present invention, a used diaper can be easily and completely stored in a processing bag in a compact manner.
There is no odor or hygiene concerns before disposal, and since there is no conventional tape, there is no danger of strongly touching the skin, and the operation of changing diapers becomes easy.
