Patent number: 7910795Abstract: A technique for imparting latent elasticity to components of an absorbent article is provided. More specifically, a latent elastic film that contains a crosslinkable semi-crystalline polyolefin is initially incorporated into an absorbent article. The film is not highly elastic prior to crosslinking and is thus dimensionally stable. Consequently, the film need not be maintained in a mechanically stretched condition during attachment to other components of the absorbent article, which provides for greater freedom in the location and manner in which the components are attached together. Once incorporated into the absorbent article, the semi-crystalline polyolefin is crosslinked to form a three-dimensional network having elastic memory. The film may also be heat activated, either through crosslinking or an additional step, to cause the film to shrink and further improve its stretch characteristics.Type: GrantFiled: March 9, 2007Date of Patent: March 22, 2011Assignee: Kimberly-Clark Worldwide, Inc.Inventors: Oomman P.

Publication number: 20100312218Abstract: The present invention aims to provide a wearing article improved so that front and rear waist regions can be easily and normally engaged with each other. A front waist region 8 is provided along a pair of opposite side edges 11 with first fastening members 13, and a rear waist region 9 is provided along a pair of opposite side edges 12 with second fastening members 14 adapted to be engaged with the associated first fastening members 13. Each of the second fastening members 14 is formed with an uneven structure having a plurality of crests 17 extending in a transverse direction X and spaced one from another in a longitudinal direction Y. Even when the uneven structure formed by the uneven region 16 as the latter 16 contracts comes in contact and engagement with the first fastening member 13, a degree of engaging force between the uneven structure and the first fastening member 13 is extremely weak and the uneven structure can be easily disengaged from the first fastening member 13.Type: ApplicationFiled: August 14, 2008Publication date: December 9, 2010Applicant: UNI-CHARM CORPORATIONInventors: Makoto Ichikawa, Naoto Ohashi
