Patent number: 6761957Abstract: The ability to transport body liquids in consumer products such as diapers, incontinents and feminine napkins is a key factor in their performance. This invention is designed to provide specific high fluxes (volume of liquid/(time*mass of polymer) of aqueous liquids in designated directions using bundles of new specially designed fibers. The key factors for the bundles are a high specific adhesion for the liquid of interest, a high specific volume of the bundle itself, and alignment of the fibers within the bundle. The invention includes novel liquid acquisition/distribution systems and absorbent products that include a liquid acquisition/distribution system which may incorporate the novel bundles of fibers.Type: GrantFiled: November 18, 1999Date of Patent: July 13, 2004Assignee: Clemson University Research FoundationInventors: Bobby Mal Phillips, Jackson Lee Nelson, Shriram Bagrodia

Patent number: 6761709Abstract: A liquid reception device is disclosed as a component, for example, of a personal care product such as a disposable diaper, an incontinent garment, or for other applications such as, for example, an industrial soaker pad or the like. The device includes liquid activated means to move a liquid insult from a target zone to a peripheral zone. The liquid activated transport means is operated mechanically by suction created by compression or vacuum or by physical movement of a liquid container from the target zone to the peripheral zone. The disclosed device provides increased use of available liquid handling capacity.Type: GrantFiled: April 12, 2002Date of Patent: July 13, 2004Assignee: Kimberly-Clark Worldwide, Inc.Inventors: Michael Tod Morman, Bryan David Haynes, Thomas Harold Roessler

Publication number: 20040127864Abstract: A diaper includes a liquid-absorbent core extending between front and rear waist regions, a liquid-pervious first sheet covering upper and lower surfaces of the core and a liquid-impervious second sheet. The diaper is formed with a cleaved zone continuously extending in the front waist region and the crotch region in a longitudinal direction of the diaper and extending through the core. Along the cleaved zone, an upper covering section of the first sheet extends downward from the upper surface of the core and a lower covering section of the first sheet also extends downward along the cleaved zone. The upper and lower covering sections extend outward in a transverse direction of the diaper symmetrically about the cleaved zone to define a penis pocket below the cleaved zone.Type: ApplicationFiled: December 12, 2003Publication date: July 1, 2004Inventor: Tomoko Sugito
