Patent number: 7744576Abstract: An absorbent article, preferably a disposable absorbent article such as a diaper, is disclosed having an absorbent core which imparts increased wearing comfort to the article and makes it thin and dry. The absorbent core useful for an absorbent article comprises a substrate layer, a discontinuous layer of absorbent material, and a layer of thermoplastic material. A second surface of the discontinuous layer of absorbent material is in at least partial contact with a first surface of the substrate layer. Portions of a second surface of the layer of thermoplastic material are in direct contact with the first surface of the substrate layer and portions of said second surface of the layer of thermoplastic material are in direct contact with a first surface of the discontinuous layer of absorbent material. A process for providing a storage layer for an absorbent core useful in an absorbent article is further disclosed.Type: GrantFiled: February 11, 2004Date of Patent: June 29, 2010Assignee: The Procter & Gamble CompanyInventors: Ludwig Busam, Uwe Jurgen Becker, Michael Divo, Bruno Johannes Ehrnsperger, Roland Engel, Torsten Lindner, Siegfried Link, Volker Maier, Sanaul Kabir Siddiquee, Gabriele Stiehl, Thomas Tombuelt

Publication number: 20100160885Abstract: An absorbent pad including a chassis having a first side edge and a second side edge. The chassis includes a liquid pervious topsheet and a liquid impervious backsheet. An absorbent system is disposed between the topsheet and the backsheet. An elastic element is disposed along each of the first and second side edges of the chassis and attached to at least one of the topsheet and the backsheet, the elastic elements generating a cupping action so that the absorbent pad is biased towards a cup-like shape. A first side adhesive element is attached to the chassis inwardly from the first side edge of the chassis. A second side adhesive element is attached to the chassis inwardly from the second side edge of the chassis. A central adhesive element is attached to the chassis between the first and second side adhesive elements.Type: ApplicationFiled: December 24, 2008Publication date: June 24, 2010Inventor: Richmond R.

Publication number: 20100152693Abstract: A feminine care absorbent article has a longitudinal axis, a transverse axis, and an absorbent structure configured for disposition adjacent a female wearer's vaginal region to absorb bodily fluids discharged by the wearer. The absorbent structure has end portions and a middle portion located between the end portions. The absorbent structure has at least one line of weakness disposed in one of the end portions and configured to facilitate folding of the absorbent structure in a longitudinal direction in response to a lateral compressive force. The absorbent structure has a relief for inhibiting the longitudinal folding of the absorbent structure facilitated by the at least one line of weakness from extending beyond the middle portion of the absorbent structure.Type: ApplicationFiled: December 15, 2008Publication date: June 17, 2010Applicant: KIMBERLY-CLARK WORLDWIDE, INC.Inventors: Carmen Lira, Adrienne Rae Loyd

Publication number: 20100152642Abstract: An absorbent article includes an absorbent body in contact with a moisture activatable shrinking yarn in the form of a metering string. The metering string includes a hanging portion that is at least initially visible to a user when the absorbent article is in use. By observing the change in length of the hanging portion, a user wearing the absorbent article can determine how saturated the absorbent article has become. The metering string may be used with absorbent articles such as tampons and diapers.Type: ApplicationFiled: December 17, 2008Publication date: June 17, 2010Inventors: Jaeho Kim, John Gavin MacDonald

Publication number: 20100152697Abstract: [Problem] To prevent a diaper from causing leakage by controlling displacement or deformation of an absorbent pad resulting from body movements. [Means for Solving Problem] A disposable diaper in the present invention is configured in such a manner that a section corresponding to a first portion at the longitudinal intermediate of the inner elastic members 13i is designated as an unfixed section 14 where a back sheet 1 and an outer sheet 12 are not fixed; a section corresponding to a second portion on the both longitudinal sides of the unfixed section 14 is designated as a fixed section, where the back sheet 1 and the outer sheet 12 are fixed; the unfixed section 14 with the inner elastic members 13i is not fixed to the back sheet 1 or the outer sheet 12, or is fixed only to the outer sheet 12; and the fixed section with the inner elastic members 13i is fixed to the back sheet 1 and the outer sheet 12.Type: ApplicationFiled: July 18, 2008Publication date: June 17, 2010Inventor: Yuki Nakano

Publication number: 20100137823Abstract: An absorbent article includes a chassis extending about a longitudinal axis and having a topsheet, a backsheet and an absorbent structure disposed between the topsheet and the backsheet. The chassis has a first transverse axis dividing the absorbent structure into a front body panel terminating in a front waist region and a rear body panel terminating in a rear waist region. The rear waist region has a first elastic region. The chassis is delimited by opposed longitudinal edges and opposed transverse edges. In the rear waist region, the absorbent structure terminates at a first distance from the transverse edge and the first elastic region extends substantially parallel to the transverse edge and spaced therefrom by a second distance and spaced from the absorbent structure by a third distance. The third distance is greater than said second distance or substantially equal thereto.Type: ApplicationFiled: May 21, 2007Publication date: June 3, 2010Applicant: SCA Hygiene Products ABInventors: Helena Corneliusson, Rozalia Bitis, Ingrid Stjernholm
