Patent number: 8951239Abstract: A disposable diaper has an absorbent body, an outer covering sheet and two end holding sheets, and both end portions of the absorbent body are fixed between the end holding sheets and the outer covering sheet. Since a turndown portion of an upper end portion of the end holding sheet is bonded on an upper end portion of a first covering sheet, a waist covering portion has structure where the first covering sheet is laminated on the two-layered end holding sheet. Therefore, a thickness of the outer covering sheet can be reduced, while maintaining strength of the waist covering portion by appropriately selecting material of the end holding sheet, thereby to easily improve softness of the disposable diaper. Since an upper end of a second covering sheet is positioned below the turndown portion, softness and breathability in an area between the turndown portion and the second covering sheet is increased.Type: GrantFiled: July 11, 2011Date of Patent: February 10, 2015Assignee: Livedo CorporationInventors: Kenji Nakaoka, Yuki Takahashi

Patent number: 8808264Abstract: An absorbent article providing improved body fit. The absorbent article includes an extensible fluid permeable facing layer and a first absorbent layer joined to the facing layer. Each zone of extensibility is a region of the first absorbent layer of relatively higher extensibility than regions of first absorbent layer adjacent to the zone of extensibility. A liquid impermeable backsheet is joined to the facing layer at the periphery. The liquid impermeable backsheet has a garment facing surface. A fastening means is disposed on at least a portion of the garment facing surface of the liquid impermeable backsheet. The fastening means defines attachment zones. At least a portion of the first absorbent layer is decoupled from the attachment zones of the fluid impermeable backsheet.Type: GrantFiled: August 3, 2012Date of Patent: August 19, 2014Assignee: The Procter & Gamble CompanyInventor: Bruce William Lavash

Patent number: 8784397Abstract: A leg wrap structure is provided in a disposable absorbent garment such as a diaper or training pants. The leg wrap structure has a base layer, a top layer, and an elastic construction disposed therebetween. The elastic construction includes a plurality of spaced apart (e.g. generally equally spaced apart) elastic elements (e.g. strands or threads) that are aligned in a generally in generally parallel relation. Further, the top and base layers define a region of inelasticity. The leg wrap structure provides for the efficient formation of a reservoir and a plurality of fluid dams each capable of capturing a quantity of fluid to minimize the occurrence of fluid leaks from the absorbent article. Methods of forming such absorbent articles are disclosed.Type: GrantFiled: April 21, 2010Date of Patent: July 22, 2014Assignee: DSG Technology Holdings Ltd.Inventors: Kuo-Shu Edward Chang, Anne Smid, Patrick King Yu Tsang, Ian Walker, Andrew Wright

Patent number: 8758319Abstract: In a standing part (342) of each side wall part (34) in an absorbent product (1), an inwardly bending part (3423) is formed between a first elastic member (35) and a second elastic member (36). When the absorbent product (1) is worn, the inwardly bending part (3423) where no elastic member is provided comes into contact with a wearer to be deformed into surface shape, and a portion in the vicinity of the inwardly bending part (3423) and the first elastic member (35) contacts with the wearer in surface shape. Therefore, the wearer is prevented from being compressed excessively by the first elastic member (35) and the second elastic member (36) and excrement is prevented from leaking out to the outer side of the absorbent product (1).Type: GrantFiled: September 1, 2010Date of Patent: June 24, 2014Assignee: Livedo CorporationInventor: Yuki Takahashi
