Patent number: 7819853Abstract: Variable stretch composites having one or more first elastomeric members disposed on a first region of an extensible substrate, and one or more second elastomeric members disposed on a second region of the extensible substrate which different from the first elastomeric members to provide variable properties to said regions of the composite. The composite has been incrementally stretched to at least partially break up the structure of the substrate in order to reduce its resistance to stretch. The variable stretch composites are useful for disposable and durable articles, such as disposable absorbent articles including diapers, pull-on diapers, training pants, incontinence briefs, catamenial garments, baby bibs, and the like, and durable articles like garments including sportswear, outerwear and the like. The present invention also relates to methods of forming such variable stretch composites.Type: GrantFiled: May 22, 2006Date of Patent: October 26, 2010Assignee: The Procter & Gamble CompanyInventors: Fred Naval Desai, Urmish Popatlal Dalal, Donald Carroll Roe

Patent number: 7781640Abstract: A disposable absorbent article including a wetness sensation member and visible highlighting indicating the presence of the wetness sensation member to facilitate an opportunity for the toilet training of the wearer. The wetness sensation member includes a permeable layer and a flow control layer. Urine deposited on the wetness sensation member can penetrate through the permeable body-facing layer in a z direction away from the wearer to the flow control layer. The flow control layer retards the passage of the urine through the wetness sensation member in the z direction while supporting the movement of the urine in an x-y plane to increase the wetted area contacting the wearer's skin and thereby enhance the wearer's awareness that urination has occurred. The visible highlighting is visible when viewing a body-facing surface of the article and may be associatively correlated with an externally visible marking and/or with the concept of toilet training.Type: GrantFiled: November 17, 2005Date of Patent: August 24, 2010Assignee: The Procter & Gamble CompanyInventors: Mary Elizabeth Davis, Donald Carroll Roe, Patrick Jay Allen, Edward Paul Carlin
