Patent number: 5952043Abstract: Wet-like cleaning wipes and similar articles that are particularly useful in removing perianal soils. These wipes comprise a carrier substrate such as tissue paper web and a emulsion applied to the substrate, wherein the emulsion comprises a continuous external lipid phase and a dispersed internal polar phase (e.g., water). The continuous external lipid phase of this emulsion is sufficiently brittle that it ruptures when subjected to low shear during use to release the dispersed internal polar phase.Type: GrantFiled: August 25, 1998Date of Patent: September 14, 1999Assignee: The Procter & Gamble CompanyInventors: Larry Neil Mackey, Arthur Wong, Edward Aprahamian, Jr., Gayle Marie Frankenbach, Magda El-Nokaly, Godfrey Reiter, Paul Seiden, John Michael Blevins, John William Toussant, Paul Dennis Trokhan

Patent number: 5800654Abstract: Disclosed is a sanitary napkin having flaps folded over the topsheet. This arrangement helps to maintain the topsheet in a sanitary condition and is more convenient for the wearer than a configuration having the flaps folded over the backsheet. The flaps may be maintained in this folded arrangement by a unitary release strip which bridges the flaps and covers any adhesive used to attach the flaps to the undergarment. If desired, the release paper may further wrap the longitudinal side margins of the sanitary napkin to additionally cover adhesive disposed on the central portion of the backsheet. If desired, the flaps may be folded over the topsheet, overlap each other and be adhesively joined to the other flap.Type: GrantFiled: January 10, 1997Date of Patent: September 1, 1998Assignee: The Procter & Gamble CompanyInventors: Elizabeth Jean Davis, Thomas Ward Osborn, III

Patent number: 5776121Abstract: Absorbent articles, such as disposable diapers, having two waist regions and a crotch region are provided. The absorbent articles comprise a liquid pervious topsheet, a liquid impervious backsheet, an absorbent core disposed between the topsheet and the backsheet, and a pair of longitudinally extending barrier cuffs. The barrier cuffs are formed from a lateral extension of the topsheet and the backsheet in at least the crotch region of the absorbent article using material that is normally discarded when the crotch area is formed. A cuff area is defined by pairs of laterally opposed cuts in the lateral extension of the topsheet and the backsheet. The cuff area is then folded and joined to the topsheet or other underlying structure to form the barrier cuff and an optional gasketing cuff.Type: GrantFiled: March 20, 1996Date of Patent: July 7, 1998Assignee: The Procter & Gamble CompanyInventors: Donald Carroll Roe, Frank Heinrich Bakes, Dean Jeffrey Daniels, Kimberly Ann Dreier, Michael Thomas Huber, John Carroll Molander
