Patent number: 8870843Abstract: A disposable absorbent product extends longitudinally along a longitudinal axis and laterally along a transverse axis, with the transverse axis conceptually dividing the product into first and second hemispheres. The product has a permeable topsheet, an impermeable backsheet overlaying the topsheet, and an absorbent core disposed between the topsheet and the backsheet for storing fluid secreted by the wearer of the disposable absorbent product. Each of a pair of side regions extends laterally outboard of the absorbent core, with each side region having a first face configured to face the wearer during use and a second face opposite the first face. The product also has at least one skin-friendly adhesive element in the first hemisphere in at least one of the side regions for temporarily attaching the disposable absorbent product to the skin of the wearer.Type: GrantFiled: August 7, 2012Date of Patent: October 28, 2014Assignee: SCA Hygiene Products ABInventors: Eugene Patrick Dougherty, Jr., Raymond Martin Carter

Publication number: 20140135722Abstract: A disposable absorbent product includes a topsheet, a backsheet overlaying the topsheet, and an absorbent core disposed between the topsheet and the backsheet for absorbing fluid secreted by a wearer of the product. The product also includes a wetness indicating material in the topsheet, the backsheet, or the absorbent core, with the wetness indicating material having a water-soluble element and an inodorous component trapped by the water-soluble element. The water-soluble element is configured to degrade in the presence of fluid secreted by the wearer of the product, thereby releasing the inodorous component into the surrounding air.Type: ApplicationFiled: November 13, 2012Publication date: May 15, 2014Inventors: Eugene Patrick DOUGHERTY, Jr., Frank Stephen GLAUG, Raymond Martin CARTER
