Patent number: 9066836Abstract: Absorbent articles having a liquid permeable topsheet, a liquid impermeable backsheet, and an absorbent core disposed between said topsheet and said backsheet are disclosed. The backsheet has a physical variation along at least one axis, wherein said physical variation defines a first backsheet zone and a second backsheet zone, and at least one elastomeric element having at least one primary direction of stretch, said elastomeric element at least partially overlapping and joined to first and/or second backsheet zone, wherein a relaxed pathlength of said elastomeric element in the primary direction of stretch is less than a total pathlength of said backsheet in the region of overlap. The physical variation is a measurable difference as measured by a physical property selected from the group consisting of basis weight, thickness and density.Type: GrantFiled: November 14, 2013Date of Patent: June 30, 2015Assignee: The Procter & Gamble CompanyInventors: Donald Carroll Roe, Pankaj Nigam, Mark James Kline, Jeromy Thomas Raycheck, Carl Louis Bergman

Publication number: 20140155810Abstract: Disclosed is a tampon applicator package assembly having a tampon applicator and a cap having a closed end and an open end. The tampon applicator has a barrel for housing a pledget and a plunger. The plunger has an end portion that is a cap cover that connects to a remainder of the plunger and mates with the cap at the open end to provide a seal with the cap that completely encloses the tampon applicator in the cap. Also disclosed is an assembly having a tampon applicator, a cap having both a closed end and open end, and a cap cover for covering the open end of the cap. When the cap cover is placed on the open end, the open end is sealed and the tampon applicator is completely enclosed in the cap.Type: ApplicationFiled: June 25, 2013Publication date: June 5, 2014Inventors: Sezen BUELL, Richard B. TIMMERS, Pankaj NIGAM, Ricardo de OLIVEIRA, Scott OSIECKI, Philip BURKHARDT, Adeyinka ABDUL

Patent number: 8684990Abstract: A simple disposable pant-like garment includes an absorbent assembly attached to a chassis. The absorbent assembly includes an absorbent core that may contain superabsorbent particles, which may be contained inside pockets. The absorbent assembly is folded laterally inward at both of its side edges to form laterally opposing side flaps. Each side flap is attached to an interior surface of the absorbent assembly adjacent to its end edges. A longitudinally extending elastic gathering member is attached to each side flap adjacent to its proximal edge. When the article is worn, the elastic gathering members contract and raise the side flaps to form breathable side barriers. The chassis includes a water-impermeable sheet and may be extensible. The absorbent assembly may be attached in a cruciform pattern such that portions of the chassis that lie outside the attachment pattern are not restrained by attachment to the absorbent assembly and therefore remain extensible.Type: GrantFiled: September 12, 2005Date of Patent: April 1, 2014Assignee: The Procter & Gamble CompanyInventors: Gary Dean LaVon, Pankaj Nigam

Publication number: 20070049897Abstract: A simple disposable absorbent article, which can be a pull-on garment, includes a chassis and an absorbent assembly. A belt is fastenable to the chassis, and both the belt and the chassis can be independently extensible or substantially inextensible. The belt can be fastened to the chassis at opposing ends, at least one of which being releasable and refastenable to induce a tension in the belt and a contractive force on the underlying chassis, thereby enhancing the fit of the garment at the wearer's waist. The belt can further define a frangible region that can be broken to define opposing outer ends, at least one of which can be drawn and refastened to induce the contractive force on the underlying chassis.Type: ApplicationFiled: August 24, 2005Publication date: March 1, 2007Inventors: Gary LaVon, Stephen Lange, Kara Cain, Pankaj Nigam
