Patent number: 8273069Abstract: A stretchable composite sheet used in a waist region of a disposable wearing article. The stretchable composite sheet has a stretchable sheet and a non-stretchable sheet, and the stretchable sheet is stretched. Nip roll mechanisms are respectively arranged on one end side in the stretch direction (SD) and the other end side, and the stretchable sheet is bonded to the non-stretchable sheet by the nip roll mechanisms with the stretchable sheet contracted in the direction (CD) orthogonal to the stretching direction (SD). The above processes provide the stretchable composite sheet with basic weight change regions in which the basis weight of the stretchable sheet is changed depending on stretch conditions of the stretchable sheet. The basic weight of the basic weight change regions is greater than that of a center region of the stretchable composite sheet.Type: GrantFiled: April 2, 2008Date of Patent: September 25, 2012Assignee: Uni-Charm CorporationInventors: Kyota Saito, Mariko Takeuchi, Yusuke Kawakami

Patent number: 8246597Abstract: A pant-type wearing article configured so as to prevent a lateral zone of a front waist region and an associated lateral zone of a rear waist region which should remain fastened together from being needlessly disengaged from each other. In the pant-type wearing article an outer surface of a base sheet strip constituting a front fastener component is bonded to a fixed region defined on an inner surface of a front lateral zone. The front lateral zone includes a free region to which the base sheet strip is not bonded. The free region normally takes a posture folded back in a waistline direction so that an outer surface of the front lateral zone lies inside.Type: GrantFiled: April 20, 2009Date of Patent: August 21, 2012Assignee: Uni-Charm CorporationInventors: Akiyoshi Kinoshita, Natsuko Aoyagi, Kayoko Tanaka, Yasuhiko Kenmochi

Patent number: 8235959Abstract: A process is claimed for making a composite sheet useful as topsheet with one or more openings to receive fecal material useful for an absorbent article, said composite sheet comprising a wrinkled, patterned elasticized region that comprises a patterned first sheet and an elastic material said first sheet being patterned with troughs, that are typically compacter, i.e. of higher density, prior to attachment to the elastic material. The troughs are attached to the elastic material. The resulting composite sheet has a uniform wrinkle pattern. Also claimed are specific absorbent articles. Also claimed are composite sheets with a specific residual strain and peel force value.Type: GrantFiled: December 5, 2008Date of Patent: August 7, 2012Assignee: The Procter Gamble CompanyInventors: Ekaterina Anatolyevna Ponomarenko, Mattias Schmidt, Tina Brown (née Lehmann)r, Alexander Eberhard Unger, Alexander Berk, Darrell Ian Brown, Blanca Arizti

Publication number: 20120191057Abstract: The present invention aims to provide a wearing article adapted to prevent unintentional displacement of a crotch region relative to front and rear waist regions by elastics attached to the crotch region. A diaper includes front and rear waist members, a crotch member by the intermediary of which the front and rear waist members are connected with each other. The rear waist member is formed with a waist fit section and an appendix section. Of the crotch member, front and rear ends including front and rear end flaps are bonded to the front and rear waist members, respectively, to form front and rear bonded regions. Both side flaps are provided on respective inner surfaces thereof with gasket elastics attached thereto. Each of the gasket elastic overlaps at one end with a part of the front waist elastic and overlaps at the other end with a part of the appendix section elastic. Furthermore, the one end overlaps with the front bonded region and the other end overlaps with the rear bonded regions.Type: ApplicationFiled: September 27, 2010Publication date: July 26, 2012Applicant: UNI-CHARM CORPORATIONInventors: Shunsuke Takino, Shunsuke Masaki

Patent number: 8221372Abstract: Provided is a disposable diaper, in which fastening tapes are brought into direct engagement with the surface of an outer-face back sheet made of a nonwoven fabric. The disposable diaper is enabled to adjust its size slightly according to the body shape of a baby, by improving the force of the fastening tapes to engage with the outer-face back sheet and the force to join the outer-face back sheet and a leakage-preventing sheet. The disposable diaper has its outer-face back sheet made of a nonwoven fabric prepared by an air-through method, in which fibers are thermally melted to each other at the time of manufacturing the nonwoven fabric by feeding hot air in a drum transfer process.Type: GrantFiled: June 15, 2006Date of Patent: July 17, 2012Assignee: Daio Paper CorporationInventors: Shinichi Kouno, Tsuyoshi Utsunomiya, Sadanao Manabe, Toshikazu Maeda, Yumiko Seike, Miyuke Ochi

Patent number: 8206366Abstract: A pant-like, prefastened, disposable absorbent article having two leg openings which are directly below and visible through a waist opening. The waist opening has a relaxed waist opening measurement or relaxed waist diameter that is greater than a width of a chassis of the absorbent article in a crotch region. As such, the wearer's legs are positioned within and through the leg openings for easy application of the pant-like prefastened, disposable absorbent article. After initial application of the absorbent article, a waist size adjustment feature allows the waist perimeter dimension to be adjusted to conform the waist opening to the waist of the wearer.Type: GrantFiled: December 7, 2001Date of Patent: June 26, 2012Assignee: Kimberly-Clark Worldwide, Inc.Inventors: Paul Joseph Datta, Michael Francís Drymalski, Kristi Jo Bryant

Publication number: 20120150137Abstract: A film that contains a thermoplastic composition having a substantial portion of a renewable, natural starch polymer, and yet is elastic and exhibits good strength properties, is provided. Although starch is normally chemically incompatible with most elastomeric polymers due to their different polarities, the present inventors have discovered that phase separation may be minimized by selectively controlling certain aspects of the film, such as the nature of the elastomeric polymer and the starch polymer, and other film components, the relative amount of the film components, and the process for making the film.Type: ApplicationFiled: December 8, 2010Publication date: June 14, 2012Applicant: KIMBERLY-CLARK WORLDWIDE, INC.Inventors: James H.
