本発明は、使い捨ておむつの粘着テープ、特に粘着面の

の欠点がある。In conventional adhesive tapes of this type, adhesive is applied to the entire adhesive surface of the tape in a substantially uniform thickness. When the diaper is put on, the adhesive surface coated with an adhesive on the free end area of the adhesive tape is fixed to the back sheet of the diaper. Generally, the back sheet is made of a thin flexible synthetic resin film such as polyethylene, so in order to check for defecation or to re-tighten the waist, the adhesive side of the adhesive tape that is attached to it is peeled off from the back sheet. When doing so, there are disadvantages such as damage to the back sheet and difficulty in peeling off the adhesive surface of the adhesive tape due to its elongation.

テープに存する。The main object of the present invention is to eliminate the above-mentioned drawbacks by applying a creative design to the adhesive surface of an adhesive tape.
To achieve this object, the present invention provides an adhesive tape for a disposable diaper comprising adhesive tapes for fastening the waist portion of the diaper body at both ends of the diaper body. The adhesive tape is characterized in that the adhesive surface is formed by grooves and protrusions that are alternately arranged in the length direction and oriented in the width direction.

ある。As shown in FIGS. 2 to 4, the adhesive tape 2 is provided with an adhesive surface 3 formed by coating an adhesive on its tip region and a non-adhesive gripping portion 4 at its outer end. The adhesive surface 3 is formed by concave stripes 5 and convex stripes 6 that are alternately located in the length direction of the adhesive tape 2 and parallel in the width direction. In the embodiments shown in FIGS. 2 and 3, no adhesive is present in the grooves 5, and in the embodiment shown in FIG. 4, adhesive is present in the grooves 5. Although it varies depending on the area of the adhesive surface 3, in general, the width of the grooved portion 5 is 1 to 5 mm, the width of the raised portion 6 is 3 to 10 mm, and the width of the grooved portion 5 relative to the adhesive surface 3 is 1 to 5 mm.
The occupied area ratio is 50% or less, preferably 10 to 30 inches.

織布９を位置せしめるためのものにほかならない。As shown in FIGS. 2 to 4, the base material 7 of the adhesive tape 2 is composed of a flexible synthetic resin film 8 and a non-woven fabric 9 integrated into one composite body, and the tip of the adhesive tape 2 is shaped so that the sides of the film 8 are in contact with each other. The section is folded back, and each layer of the folded section is integrated into a composite structure. The reason why the film 8 and the non-woven fabric 9 are integrated in this way is to give the base material 7 the necessary rigidity and to position the non-woven fabric 9 with a good feel on the side of the child's desk. .

It is preferable that it is 10 tm. However, the present invention is not limited to this size.

The following steps will be described with reference to FIGS. 5 and 6. Note that the adhesive tape 2a shown in FIG. 5 has an adhesive surface 3a having a uniform thickness, and the adhesive tape 2 shown in FIG.
This invention relates to the embodiments shown in FIGS. 2 and 3 described above (the following description also applies to the embodiment shown in FIG. 4). Further, FIGS. 5 and 6 are cross-sectional views of the diaper being worn and the adhesive surfaces 3, 3a of the adhesive tape 2.2a fixed to the back sheet 10 of the diaper.

易い。While the diaper is being worn, shear stress in the direction of the arrow atb is always applied to the interface between the sticky surfaces 3, 3a and the back sheet 10, especially at the boundary edges between the two or the back sheet 1.
Strain is accumulated in the back sheet 10 by concentrating strain on areas where the thickness and molecular orientation are uneven and the strength is low. Therefore, in the case shown in FIG. 5, when the adhesive surface 3a is peeled off from the back sheet 10, the back sheet 10 is likely to tear from the portion where strain has accumulated. However, in the case shown in FIG. 6, since the adhesive surface 3 is discontinued in the peeling direction, the strain accumulated in the back sheet 10 described above is caused to spread from one end of the adhesive surface 3 to the other end. distributed between As a result, the strain accumulated on the back sheet 10 is significantly less than in the case shown in FIG. 5, and when the adhesive surface 3 is peeled off from the back sheet 10, there are fewer defects as in the case shown in FIG. . Furthermore, since the back sheet 10 has less distortion as described above, it is separated from the adhesive surface 3 while maintaining a relatively clean state. Furthermore, since the elongation of the back sheet 10 is prevented from increasing gradually as the adhesive surface 3 is peeled off, the adhesive surface 3 can be easily peeled off.
