PULL-ON DIAPER

Abstract

A pull-on diaper includes a front waist region and a rear waist region joined together along joints defined by transversely opposite edges of these waist regions so as to form a waist-hole and a pair of leg-holes. The joints are adapted to be ruptured for disposal of the diaper which has been used. The front waist region and the rear waist region are joined together along the joints by means of joining members and each of the joining members is provided with a gripper formed integrally with this joining member and rupture guides extending from the gripper toward the waist-hole and the associated one of the leg-holes.

Claims

1. A pull-on diaper comprising a front waist region and a rear waist region joined together along joints defined by transversely opposite edges of said waist regions so as to form a waist-hole and a pair of leg-holes; said joints being adapted to be ruptured for disposal of the diaper which has been used;said front waist region and said rear waist region being joined together along said joints by means of joining members; andeach of said joining members being provided with a gripper formed integrally with the joining member and rupture guides extending from said gripper toward said waist-hole and the associated one of said leg-holes, respectively.

2. The pull-on diaper defined by claim 1, wherein said gripper is a finger-grip formed by making a cut in a part of said joining member and said rupture guides extend from upper and lower roots of said finger-grip, respectively.

3. The pull-on diaper defined by claim 1, wherein said rupture guides respectively comprise a plurality of incisions arranged to extend stepwise from said gripper toward said waist-hole and associated one of said leg-holes, respectively, at given intervals.

4. The pull-on diaper defined by claim 3, wherein said rupture guides respectively comprise a plurality of incisions arranged to extend stepwise from said gripper toward said waist-hole and associated one of said leg-holes, respectively, at given intervals and each pair of the adjacent incisions partially overlap each other as viewed in a direction orthogonal to a longitudinal direction of said incisions.

5. The pull-on diaper defined by claim 3, wherein said joining member is made of a fibrous nonwoven fabric comprising fibers oriented in on direction and a length of said incision is shorter than a length of said fibers; wherein a distance between each pair of the adjacent said incisions is the same as or shorter than said length of said incisions; and wherein said longitudinal direction of said incisions is orthogonal to said one direction in which said fibers of said fibrous nonwoven fabric are oriented.

6. The pull-on diaper defined by claim 1, wherein said gripper is located between said waist-hole and the associated one of said leg-holes.
