Abstract

This diaper (1A) is provided with: an absorbent main body (2) including an absorbent (23), a surface sheet (21), and an outer-layer composite sheet (22); and an elastic side panel (3) attached to a lateral part of the absorbent main body (2). A fastening tape (4) is provided to a distal end part (3a) of the side panel (3). The absorbent main body (2) has a three-dimensional-guard forming sheet (24) at both lateral parts thereof. The three-dimensional-guard forming sheet (24) has a two-layer-structure portion (24a) and a three-layer-structure portion (24b) in which both lateral parts of a single sheet are folded back and layered over each other, and the layers are bonded together. The three-dimensional-guard forming sheet (24) is fixed at both lateral parts of the absorbent main body (2) to a sheet (31) constituting the side panel (3).

Description

technical field [0001] The present invention relates to an unfolded disposable diaper. Background technique [0002] Conventionally, there has been known an unfolded disposable diaper in which an elastic body that expands and contracts along the width direction of the absorbent body is installed on a portion disposed on the wearer's back side in an absorbent body including an absorbent body. side panels (refer to Patent Document 1). [0003] Such a disposable diaper can be manufactured by manufacturing side flap sheets in a process different from that of the absorbent body and adding them to the absorbent body, so that the amount of materials used for the side flaps or waste generated from the materials can be suppressed, Excellent in terms of environment or cost. [0004] However, conversely, when the diaper is worn by stretching the hook and loop fastener provided at the front end portion of the side panel, the junction of the side panel and the absorbent main body and i...
