Abstract

The invention is a disposable diaper (1) provided with: an absorbent body (2) comprising an absorbent (23) and an outer composite sheet (22); and expandable side panels (3). The side panels (3) have two sheets (31, 32) and an elastic member (33), and have fastening tape (4) at the leading edge (3a). The outer composite sheet (22) has an anti-leak sheet (22a) and an outer nonwoven fabric (22b) that is joined thereto by means of an outer adhesive layer (61). The side panels (3) have main body side and base end side adhesive layers (35, 36). The base end (3b) is reinforced by means of a reinforcing adhesive layer (63) that overlaps or is continuous with the adhesive layer (35), and is joined to the outer composite sheet (22) by a connecting adhesive layer (62). The adhesive layers (35) are formed, at a distance from each other, on the outside of the adhesive layer (61) in the diaper width direction, and the adhesive layers (35, 63, 62, 61) are provided so that there are no gaps in the diaper width direction.

Description

technical field [0001] The present invention relates to a disposable diaper and a method for its manufacture. Background technique [0002] In the prior art, there is known an unfolded disposable diaper in which a part of the absorbent main body including the absorbent body, which is arranged on the wearer's back side when worn, is attached in the width direction of the absorbent main body. Stretchable side panels that stretch upward (refer to Patent Document 1). [0003] Such a disposable diaper is manufactured by manufacturing side panels in a process different from that of the absorbent main body and adding them to the absorbent main body, so that the amount of materials used for the side panels and the amount of material used for the materials can be suppressed. The generated waste is excellent in terms of environmental protection and cost reduction. [0004] But, on the other hand, when pulling the fastening tape etc. that is arranged on the front end portion of the s...
