DISPOSABLE PULL-ON DIAPER

摘要

The present invention aims to provide a disposable pull-on diaper improved so that the diaper may be conveniently put on the wearer's body.;Each of leg side flaps of a crotch panel has an outer side region and an inner side region. In the lowest region of the crotch region, the outer side region and the inner side region respectively have a dimension of at least 10 mm in a transverse direction wherein the inner side region extends in a longitudinal direction and the outer side region extends in the transverse direction from the inner side region.

1. A disposable pull-on diaper having a longitudinal direction, a transverse direction and a front-back direction wherein side edge portions opposed to each other in the transverse direction of a front panel defining a front waist region are joined to side edge portions opposed to each other in the transverse direction of a rear panel defining a rear waist region to form an annular waist region and wherein front and rear end portions of a crotch panel extending in the front-back direction to define a crotch region are joined to the front waist region and the rear waist region, respectively, wherein:
the crotch panel includes an absorbent structure located in a central portion in the transverse direction thereof and a pair of leg side flaps extending along the absorbent structure on both sides in the transverse direction thereof; and the leg side flaps are formed of nonwoven fabric sheets extending in the transverse direction from the absorbent structure and a plurality of elastic members secured under tension to the respective nonwoven fabric sheets so as to extend parallel in the front-back direction, each of the leg side flaps has a proximal edge integrated with the absorbent structure and a distal edge defining each of side edges of the crotch panel, an area extending in the transverse direction between the proximal edge and the distal edge is divided into an outer side region including the distal edge and the leg elastic members and an inner side region including the proximal edge, one of the leg elastic members is secured to the distal edge, a dimension in the transverse direction between the outer side region and the inner side region is at least 10 mm in an area extending in the transverse direction across a lowest region in the longitudinal direction, the inner side region extends upward in the longitudinal direction from the proximal edge and the outer side region extends outward in the transverse direction from the proximal edge.
