[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 temporary fixing tape.

[0002]

2. Description of the Related Art A conventional disposable diaper has a structure that naturally requires a wearer to wear the disposable diaper. That is, after the diaper is applied to the buttocks in a state where the wearer is laid down, the tip of the fastening tape is peeled off and fixed to the ventral surface of the disposable diaper.

[0003]

[Problems to be Solved by the Invention] However, it is troublesome to put the wearer to sleep every time the diaper is worn, and it is convenient if the wearer can wear the diaper while standing.
Also, when trying to attach a conventional disposable diaper while standing, press the back of the diaper against the wearer's back with one hand, and stop the disposable diaper with the other hand against the abdomen. It is necessary to peel off the leading end of the adhesive tape and fix it to the ventral surface of the disposable diaper, which is practically impossible.

Further, in recent years, a structure in which a reinforcing sheet made of a polyethylene sheet or the like having a large area is fixed in advance on the ventral surface of a disposable diaper, and a fastening tape is fixed to the reinforcing sheet has become mainstream. ing. In this case, since the reinforcing sheet is provided, if the fixing position of the fastening tape is improper, for example, if the fastening tape is fixed too loosely, the fastening tape is once peeled off from the reinforcing sheet, and the reinforcing sheet is again provided. This is advantageous in that it can be fixed at another position on the upper side.

However, once the fastening tape is peeled off from the reinforcing sheet to re-tighten, the entire disposable diaper is loosened, and skill is required to re-tighten. Furthermore, when mounting the disposable diaper, it is necessary to balance the right and left, that is, to match the center of the disposable diaper with the center of the wearer in order to prevent leakage. For this,
Although it has been developed to provide the reinforcing sheet for reattachment, and to display a fastening position on the surface of the reinforcing sheet, for example, to print a number or print a mark, first fix one of the right and left and then As long as the other is fixed, one of the right and left sides is often shifted, and it is difficult to balance, especially in the case of tight fastening.

SUMMARY OF THE INVENTION Accordingly, it is an object of the present invention to satisfy the requirement that the wearer can easily wear the product while standing up, that the wearer can easily wear it tightly, and that it is easy to balance left and right. is there.

[0007]

The above object is achieved by fixing the front end of the paper diaper to the abdominal surface via the adhesive layer on the inner surface thereof while the diaper is fixed to the base portion at the flaps on the both sides on the back side of the disposable diaper. In a disposable diaper having a tape to be fixed, a temporary fixing tape is provided on an inner surface of an adhesive layer at a tip portion of the fixing tape, and the temporary fixing tape includes a flap portion or a fixing tape on both side ends on the back side of the disposable diaper. It can be solved by having an adhesive layer for temporary fixing to the ventral surface on the inner surface of the temporary fixing tape.

[0008]

According to the present invention, since the temporary fixing tape is provided and temporarily fixed, the paper diaper can be fixed without worrying that the disposable diaper is slipped off when tightly fixed. Therefore, when mounting, it can be mounted not only in a lying state but also in a standing state.

[0009]

Next, the present invention will be described in detail with reference to examples.
FIG. 1 is an overall perspective view of the disposable diaper according to the present invention, and FIG.
FIG. 4 to FIG. 4 are cross-sectional views of the longitudinal end in the preparation for mounting and the mounting state of the paper diaper. FIG. 5 is an enlarged cross-sectional view of the fastening tape in a mounting preparation stage of FIG.

1 is a liquid-permeable sheet made of a nonwoven fabric or the like;
Is a liquid-impervious sheet such as a polyethylene sheet,
The absorber 6 is enclosed between the two sheets. Also F
Is a flap portion formed by an overlapped portion of both sheets where no absorber is present, and fastening tapes 3 are provided at both ends on the back side in the longitudinal direction so as to wrap the flap portions F and F, respectively. . The base 31 of the fastening tape 3 is fixed to the liquid-impermeable sheet 2 by a hot-melt adhesive or the like so as to be substantially inseparable, whereas the tip 32 is provided with an adhesive layer 33 on the inner surface thereof. And can be peeled off.

Further, on the liquid-permeable sheet 1 side of the back flap F on which the fastening tape 3 is provided, a release tape 41 formed of a sheet piece of polyethylene or the like cannot be peeled off by a hot melt adhesive or the like. It is fixed to. In the embodiment, a release tape 42 for temporary fixing, which is also formed of a sheet piece of polyethylene or the like, is fixed to the liquid-impermeable sheet 2 side of the abdominal flap F so as to be non-peelable by a hot melt adhesive or the like. .

On the other hand, a reinforcing tape 7 having a considerably high breaking strength is fixed vertically and horizontally on the liquid-impervious sheet 2 on the abdominal side by a hot melt adhesive or the like due to the shape of the tip of the fastening tape 3. ing. On the reinforcing tape 7, a positioning mark and a design of the fastening tape 3 are printed as in the conventional example.

The above construction is basically known, except for a temporary fixing release tape 42. In the present invention, however, the temporary fixing tape 3 is temporarily provided inside the front end portion 32 of the fastening tape 3 and between the fixing tape 3 and the release tape 41. A stop tape 5 is provided. The adhesive tape 51 is applied to the release tape 41 side of the temporary fixing tape 5, and a portion extending from a side edge of the flap F is outwardly folded. Are adhered to the inner surface of the distal end portion 32 by pressure-sensitive adhesive layers 51 and 33. Further, a knob 53 is formed by folding the inner portion inward.

The tip of the tip 32 of the fastening tape 3 is also bent inward to form a knob 34. Release tape 41
, The inner end of the knob 53, and the inner end of the knob 34 are displaced outward in this order, ensuring ease of pinching and peeling from the lower layer. Moreover, since the grip portions 53 and 34 are not adhered to the release tape 42 and the temporary fixing tape 5, respectively, the releasability is easy.

The following is the procedure for mounting the disposable diaper of the present invention. First, after the back part and the abdomen part of the diaper are inserted into the crotch of the wearer with the wearer standing, the knob 53 of the temporary fixing tape 5 is clarified in the process shown in FIGS. , And the temporary fixing tape 5 and the fixing tape 3 are peeled off as a single piece.
It is adhered to the surface of the release tape 42 for temporary fixing. The temporary fixing on both sides is not something that is tightly fixed to the wearer, but it is sufficient to temporarily fix it with enough looseness to prevent slippage, so that it can be performed even if the wearer stands.

Next, from the temporarily fixed state, as shown in FIG. 4, the fastening tape 3 is peeled off from the temporarily fixed tape 5 via the knob 34, and is brought into the abdominal reinforcing tape 7 side. At the position on the reinforcing tape 7 where the paper diaper is tightly fixed, the tip 32 of the fastening tape 3 is adhered via the adhesive layer 33. In this case, as shown in FIG. Therefore, due to the double folding, the hardness of the release tape 41 does not damage the wearer's skin as compared with the conventional case without double folding. The bonding of the fastening tapes 3 and 3 to the reinforcing tape 7 can be easily performed even if the wearer stands, since there is no fear that the disposable diaper will slip off due to the temporary fixing.

In the above example, release tape for temporary fixing
42 can be omitted if necessary. In this case,
The temporary fixing tape 5 can be fixed to an appropriate position of the liquid impermeable sheet 2 of the flap portion F.

In the present invention, the temporary fixing tape 5 is provided with a flap portion F or a fixing tape 3 at both ends on the back side of the disposable diaper.
Although the above example is an example in which it is integrated with the fastening tape 3, it can be integrated with the flap portion F. For example, as shown in FIG. 6, the temporary fixing tape 5A can be fixed to the liquid impermeable sheet 2 with a hot melt adhesive 10A or the like. Fastening tape 3
Are fixed to the temporary fixing tape 5A with the hot melt adhesive 10B. Further, as shown in FIG. 7, the temporary fixing tape 5B can be fixed to the outer fold of the release tape 41 with a hot melt adhesive 10C or the like.

[0019]

[Effects of the Invention] As described above, according to the present invention, the wearer can easily wear the product even while standing, and it is simple even when wearing it tightly. In addition, advantages such as simplicity are provided.
