Patent number: 8088967Abstract: A disposable absorbent article has a liquid permeable liner, an outer cover, and an absorbent body disposed between the liner and the outer cover for absorbing liquid body waste. A flow control layer is disposed between the liner and the absorbent body. The flow control layer is adapted to retard the flow of liquid body waste penetrating the liner toward the absorbent body. The flow control layer has a plurality of apertures for permitting at least some of the liquid body waste that passes through the liner to flow past the flow control layer toward the absorbent body without migrating laterally outward around lateral side edges of the flow control layer.Type: GrantFiled: May 28, 2009Date of Patent: January 3, 2012Assignee: Kimberly-Clark Worldwide, Inc.Inventors: Richard L.

Patent number: 8016803Abstract: An absorbent article having a backsheet, an absorbent core, a topsheet, and a genital coversheet. The topsheet has an opening positioned to allow exuded fecal material to pass therethrough when the article is worn by a wearer. The genital coversheet is positioned across a portion of the aperture and covers the wearer's genitals. A void space is formed between the genital coversheet and the absorbent core and a void space is formed between the topsheet and the absorbent core.Type: GrantFiled: September 13, 2005Date of Patent: September 13, 2011Assignee: The Procter & Gamble CompanyInventors: Joerg Mueller, Cornelia Martynus, Ralf Geilich, Simone Seeboth, Ekaterina Anatolyevna Ponomarenko, Michael I.

Patent number: 7956236Abstract: An absorbent article including a backsheet, an absorbent core, a topsheet with apertures, and a sublayer that includes at least one acquisition layer. The sublayer includes a multitude of holes. At least some of the apertures overlap partially at least some of the holes to form combined apertures in an overlap area that has an open area of between 15% and 50%. The absorbent article may provide improved isolation of feces away from the skin of a wearer of the absorbent article and/or improved immobilization of feces received by the absorbent article.Type: GrantFiled: September 22, 2006Date of Patent: June 7, 2011Assignee: The Procter & Gamble CompanyInventors: Ekatarina Anatolyevna Ponomarenko, Monika Imgard Johanning, Ralf Geilich

Patent number: 7951127Abstract: An absorbent article for fecal matter handling, especially with respect to mushy and/or pasty fecal matter, along with methods of making the same. A composite bodyside liner can reduce the amount of fecal matter that remains on the skin of a wearer after removal of the absorbent article from the wearer. The bodyside liner can include only a fluid pervious liner layer. Alternatively, the bodyside liner can include a fluid pervious liner layer and a surge layer. A fecal adhering treatment composition is applied to at least a portion of the bodyside liner to reduce the amount of fecal matter that remains on the skin of the wearer after the absorbent article is removed.Type: GrantFiled: December 15, 2006Date of Patent: May 31, 2011Assignee: Kimberly-Clark Worldwide, Inc.Inventors: Lisa M. Sanabria, Eugenio G. Varona

Patent number: 7893314Abstract: A breathable backsheet (1) includes a water vapor permeable first layer (2) and a water vapor permeable second layer (3) for an absorbent article (4), where the backsheet (1) is water vapor permeable in a Z-direction. The backsheet (1) includes a condensation zone (7) between the two layers (2, 3). The first layer (2) is adapted to allow a first amount m1 of mass flow water vapor to pass the first layer (2) in the Z-direction, wherein the second layer (3) is adapted to allow a second amount m2 of mass flow water vapor to pass the second layer (3) in the Z-direction. The condensation zone (7) is adapted to temporary condense and shore an amount t•.mc of water vapor such that no formation of condensed of water vapor will occur on the outside (6, 11) of the backsheet (1).Type: GrantFiled: October 29, 2004Date of Patent: February 22, 2011Assignee: SCA Hygiene Products ABInventors: Chatrine Stridfeldt, Solgun Drevik
