Patent number: 9782306Abstract: A secondary internal topsheet and 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 inbetween. The elastic construction includes a plurality of spaced apart elastic elements that are aligned in a generally in generally parallel relation. The leg wrap structure and secondary topsheet 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: June 30, 2014Date of Patent: October 10, 2017Assignee: DSG Technology Holdings Ltd.Inventors: Patrick King Yu Tsang, Andrew Wright, Ian Walker, Edward Kuo-Shu Chang

Patent number: 9205005Abstract: An absorbent article has a liquid-permeable top sheet of a white non-woven fabric, a liquid-impermeable back sheet opposing the top sheet, and an absorbent between the top sheet and the back sheet. A colored element is provided on the side of the top sheet that does not contact the skin, is visible through the top sheet, and is colored to a color other than white. The top sheet has protrusions and indentations in the thickness direction. The basic weight of the protrusions is greater than the basic weight of the indentations. The color difference between the Lab value of the color of the colored element visible through the protrusions of the top sheet and the Lab value of the color of the colored element visible through the indentations of the top sheet is 2.8 or more.Type: GrantFiled: September 26, 2011Date of Patent: December 8, 2015Assignee: UNICHARM CORPORATIONInventors: Kyo Kikuchi, Kei Wakasugi, Junko Ueda, Naoto Ohashi, Yasuhiro Yamanaka

Patent number: 8878000Abstract: An absorbent article having a front end region, a rear end region, a central region disposed between the front and rear end regions, a fluids source area, and a transverse axis and a longitudinal axis. The absorbent article includes a topsheet, a backsheet, an absorbent core disposed between the topsheet and the backsheet, and a reinforcing structure disposed within the central region. In one aspect of the invention, the reinforcing structure includes a pair of traverse reinforcing elements each of which is formed by two traverse channels. The two traverse channels may be disposed generally parallel to the transverse axis with a reinforcement distance such that the absorbent core has an average density of in the range of about 5% to about 500% higher at the traverse reinforcing element than the fluids source area.Type: GrantFiled: June 17, 2013Date of Patent: November 4, 2014Assignee: The Procter & Gamble CompanyInventors: Atsushi Ueminami, Maki Hasegawa

Patent number: 8852161Abstract: Absorbent garment such as a diaper and an incontinence guard, said garment has a first body panel, a second body panel and a crotch portion there between. The garment is provided with opposed laterally extending belt members attached to the waist portion of the first body panel and are adapted to be wrapped around the waist of the wearer of the garment and fastened together by a first fastener. The second body panel at its waist portion is provided with second fasteners adapted to be fastened to the belt members, in such a way that the garment will assume a pant-like shape. The belt members are interconnected by a waist band extending in transverse direction along the waist portion of the first body panel. At least one of the belt members has an elastic region located at the proximal end of said belt member adjacent said waist band.Type: GrantFiled: June 21, 2006Date of Patent: October 7, 2014Assignee: SCA Hygiene Products ABInventor: Kent Hermansson

Patent number: 8545472Abstract: In a pants-type absorbent product, a first middle elastic member is located along a horizontal direction in a middle front part between a pair of leg openings in an outer covering sheet. The first middle elastic member contracts a first sheet and a second sheet, and middle gathers are formed. Thus, it is possible to improve fitting of a middle part to a wearer. In the middle front part, both ends of the first middle elastic member are apart from edges of the pair of leg openings, and a pair of non-contracted parts are provided between the both ends of the first middle elastic member and the edges of the pair of leg openings, to thereby improve flexibility of portions in the vicinities of the leg openings in the outer covering sheet.Type: GrantFiled: September 14, 2011Date of Patent: October 1, 2013Assignee: Livedo CorporationInventors: Masaru Fujioka, Yuki Takahashi
