Patent number: 8632516Abstract: Disposable pant like garments are disclosed. Pant like garments of the present invention generally comprise a main absorbent portion and a pair of side portions. One or more sections of the pant-like garments are provided with one or more cohesive areas which allow for cohesive fastening and refastening of portions of the garment. The cohesives chosen may have the same properties or may be of the selective adhesive type. Pant like garments may be provided with cohesive fasteners and not other types of refastening means. In other variations, cohesive fasteners may be supplemented with one or more frangible bonds. Also disclosed are side portions having cohesive areas which may be converted in use from an abutting facing relationship to an overlapping facing relationship. Multiple cohesive areas of varying types for providing differential bond properties during use are also disclosed.Type: GrantFiled: November 2, 2011Date of Patent: January 21, 2014Assignee: The Procter & Gamble CompanyInventors: Gregory Ashton, Michael Charles Raufman, Frederick Michael Langdon, Donald Louis Zgoda, Mark James Kline, Robin Lynn McKiernan, Mary Lee Amirpour

Publication number: 20120271265Abstract: A stretch laminate having enhanced features is disclosed. The laminate may include a first layer of nonwoven, a second layer of an elastomeric material, a third layer of a polyethylene and/or ductile polymeric film, and optionally, a fourth layer which may also be a nonwoven. The third layer may be bonded to the second layer in a pattern that includes bonded and unbonded areas. Following lamination the laminate may be activated to impart stretchability in a stretch direction. Activation causes plastic deformation/elongation of the third layer along the stretch direction, and upon elastic contraction of the second layer the deformed/elongated third layer gathers in the unbonded areas, creating desirable visual and tactile effects. The laminate has other advantages and may be provided with other features for enhancement of visual and/or tactile effects. The laminate may be used to form components of absorbent articles such as disposable diapers and training pants.Type: ApplicationFiled: April 20, 2011Publication date: October 25, 2012Inventor: Frederick Michael Langdon
