Description

DETAILED DESCRIPTION OF THE INVENTION Industrial Field of the Invention The present invention relates to a disposable diaper having a fastening tape for fixing a diaper. Particularly, it relates to a disposable diaper that fits the waist of a wearer.

2. Description of the Related Art Conventional diapers have been devised variously in recent years to prevent leakage of urine and feces. For example, in order to prevent leakage from the crotch, it has become common to form a gather by inserting an elastic material into the part that contacts the crotch of the diaper. On the other hand, leaks from the waist of urine and feces have not been devised so much, but in some cases, elastic members are put in the waist to form gathers (Japanese Patent Laid-Open No. 59-1446).
01, JP-A-60-17101). However, since such gathering is not connected to the fastening tape, it is difficult for the gathering force to be applied to the gathering even when the tape is pulled, and it is difficult to stretch the gathering portion and attach it to the wearer. Therefore, it is difficult to completely fit the diaper to the waist portion, and the effect of preventing leakage of urine and feces from the waist portion is small. Also, JP-A-61-2760
Proposal of a diaper that has an elastic part on a part of the tape (the part that is not fixed to the diaper in advance. The part that is fixed to the ventral side of the diaper to fix it to the wearer when wearing it. The fixing part below) Has been done. Since this diaper has an elastic part and a tape part integrated, the force applied to the tape is transmitted to the elastic part, so it has some effect in fitting the waist part, but the elastic part is on the fixed part side of the tape. Therefore, there is a drawback that it is very difficult to handle when wearing a diaper because it has no waist. Also, when the diaper is attached, when pulling the tape, the force is applied to the entire stretchable part, so the stretchable member may be cut unless the stretchable member has a certain degree of hardness, and there is a limit to how soft and stretchable it is. It also has the drawback of hindering the texture and stretching effect.

SUMMARY OF THE INVENTION An object of the present invention is to provide a diaper that eliminates the above-mentioned drawbacks and fits the waist of a wearer to prevent leakage of urine from the waist.

Therefore, the present invention relates to a liquid-permeable surface sheet, a liquid-impermeable back sheet, an absorbent body interposed between the sheets and an adhesive tape as a means for fixing to the wearer, and Part of the part of the tape that is fixed to the diaper in advance by using it (hereinafter referred to as the fixing part) is made of a stretchable member, and stretches when pulled by applying force to the tape when attached. By providing it, the object of the present invention can be achieved.

In other words, by making a part of the fixing part of the adhesive tape an elastic member, when the tape is pulled, the gathering can be brought close to that part of the diaper due to the elasticity, and when the tape is attached, the tape can be pulled to extend the elastic part. Since it is reinforced by the back sheet and the front sheet, it is hard to break and it is possible to design effectively with greater elasticity, and the elastic material can be made softer. Further, when the elastic portion is not in the fixed portion, there is an advantage that the tape is easy to use.

[Brief description of drawings]

FIG. 1 is a diaper using the present invention. There are gathers by elastic parts of adhesive tape on both sides of the waist on the back side, and by pulling the adhesive tape tab, this gather stretches and the waist part of the wearer wears. Adhesion between the skin and diaper fits well and prevents excrement leakage. 2 and 3 are cross-sectional views taken along the line AA 'in FIG. 1 and are enlarged views of the places where gathers are formed by the elasticity of the elastic portion of the adhesive tape. 1: Surface material 2: Absorber 3: Adhesive fastening tape 4: Fastening tape expansion / contraction part 5: Target tape 6: Release tape 7: Back sheet
