Patent number: 6340782Abstract: A method of securing an elastic band between two material layers which are at least partially defined by meltable material includes forming perforations in the elastic band, placing the elastic band between two material layers, and bonding the material layers to one another through the perforations by heat fusion, wherein the perforations in the elastic band are formed at the same time as the material layers are fused together (i.e., the formation of the perforations in the elastic band is directly followed by bonding together, through the perforations, portions of the material layers). An elastic band secured between two material layers for inclusion in articles of one-time use includes the use of material layers that are at least partially defined by meltable material and an elastic band having perforations formed therein. The material layers are positioned on opposite sides of the elastic band and are joined together by heat fusion in a punctiform and/or linear bonding pattern.Type: GrantFiled: February 8, 1996Date of Patent: January 22, 2002Assignee: SCA Hygiene Products AktiebolagInventors: Robert Kling, Berth-Ove Wall

Patent number: 6325787Abstract: Absorbent articles such as disposable diapers, incontinent briefs, diaper holders, training pants, feminine hygiene garments and the like, that have a unique waist feature that improves the dynamic fit as well as the containment characteristics of the absorbent article. Such absorbent articles comprise a chassis assembly preferably comprising a liquid pervious topsheet, a liquid impervious backsheet, and an absorbent core positioned between the topsheet and the backsheet; an extensible back waist feature; and a closure system for maintaining the absorbent article on the wearer. The extensible back waist feature provides an extensible feature that provides a more comfortable and contouring fit by initially conformably fitting the diaper to the wearer and by sustaining this fit. The extensible back waist feature has a hip panel, a central waistband panel, and a pair of side panels. The force/extension characteristics of each panel is designed to provide such improved fit and containment.Type: GrantFiled: July 14, 1999Date of Patent: December 4, 2001Assignee: The Procter & Gamble CompanyInventors: Donald Carroll Roe, David Joseph Kenneth Goulait, Sheila Snyder Rodriguez, Edward Paul Carlin, Kimberly Ann Dreier, Carolyn Mae Jasper, Dean Jeffrey Daniels
