Publication number: 20230310225Abstract: An array of absorbent articles each having a topsheet, a backsheet, and an absorbent core is described. A first absorbent article has a first physical feature disposed between the topsheet and the absorbent core, and a second absorbent article has a second physical feature disposed between the topsheet and the absorbent core. The first physical feature has a first length between 27 and 77 percent of a first absorbent core length. The second physical feature has a second length between 27 and 77 percent of a second absorbent core length. The first length is less than the second length, and the first physical feature comprises a convex portion oriented toward a first end of the first absorbent article and/or the second physical feature comprises a convex portion oriented toward a first end of the second absorbent article.Type: ApplicationFiled: June 2, 2023Publication date: October 5, 2023Inventors: Bret Darren SEITZ, Douglas Gregory STEVENS

Publication number: 20180177648Abstract: An absorbent article comprises a chassis comprising a topsheet, a backsheet, and an absorbent core disposed between the topsheet and the backsheet, the chassis having a body-facing surface and an outer-facing surface. The article also comprises a pair of side flaps comprising a first surface, a second surface opposite the first surface, and a first adhesive. The side flaps have a proximal end and a free distal end wherein each distal end is foldable around an edge of an undergarment when applied on the undergarment during use to attach the first adhesive to the underside of the undergarment thereby attaching the absorbent article to the undergarment.Type: ApplicationFiled: December 19, 2017Publication date: June 28, 2018Inventors: Frederick Michael LANGDON, Remo BELLUCCI, Bruce William LAVASH, Callida Williams LUDHER, Douglas Gregory STEVENS

Patent number: 7979256Abstract: A method for determining absorbent article effectiveness of a virtual absorbent article. The steps of the method include providing a virtual body model, providing a virtual absorbent article model, providing virtual simulation software, running a virtual simulation of deformation of the virtual absorbent article model in proximity with the virtual body model, running a virtual simulation of the fluid balance of the virtual absorbent article model in proximity with the virtual body model, coupling the virtual simulation of deformation of the virtual absorbent article model and the virtual simulation of the fluid balance of the virtual absorbent article model, and determining absorbent article effectiveness of the virtual absorbent article model in proximity with the virtual body model.Type: GrantFiled: January 30, 2007Date of Patent: July 12, 2011Assignee: The Procter & Gamble CompanyInventors: Matthew Joseph Macura, Paul Martin Lipic, Mel Allende-Blanco, James Kenneth Comer, Jr., Douglas Gregory Stevens, Bruce William Lavash

Patent number: 7684939Abstract: A method for designing an absorbent article. The steps of the method are generating a physical spatial map of saturation of a fluid within an absorbent in a physical test environment, generating a virtual spatial map of saturation of a fluid within an absorbent in a virtual test environment, identifying absorbent-fluid interaction properties for the absorbent such that the virtual spatial map of saturation approximates the physical spatial map of saturation, inputting the absorbent-fluid interaction properties into a virtual model of the absorbent article to produce a representation of at least one feature of the absorbent article, evaluating the virtual model of the absorbent article to determine the performance of the at least one feature of the absorbent article, modifying the design of the absorbent article in response to the performance of the at least one feature of the absorbent article determined from the virtual model of the absorbent article.Type: GrantFiled: August 16, 2006Date of Patent: March 23, 2010Assignee: The Procter & Gamble CompanyInventors: Mel Allende-Blanco, Brian Bert Anderson, William Handy Hartt, IV, Paul Martin Lipic, Mattias Schmidt, Douglas Gregory Stevens, Bruno Johannes Ehrnsperger
