Absorbent article fastening device having stiffness changing characteristics

摘要

The present invention relates to a disposable absorbent article comprising a chassis defining a front waist region, a back waist region, and a crotch region disposed between the front waist region and back waist region. The article includes a fastening system that includes one or more fastening devices, each having at least one tab member configured to releasably connect to a slot member when, for instance, fastening the article to the body of the wearer. A variable stiffness member is associated with at least a portion of the fastening device that, in response to a predetermined external stimulus, reduces its stiffness to correspondingly reduce the stiffness of the fastening device.

主权项

1. An absorbent article having a front waist region, a back waist region opposed to the front waist region and a crotch region located between the front waist region and the back waist region, a pair of longitudinal edges and a pair of end edges, the absorbent article comprising:
a topsheet; a backsheet attached to the topsheet; and a fastening system including at least one fastening device configured to connect a first article location to a second article location, the fastening device including a variable stiffness member having an original stiffness before experiencing a predetermined stimulus and a permanently reduced stiffness after experiencing the predetermined stimulus, wherein the reduced stiffness is at least 10% less than the original stiffness.
