Patent number: 6613175Abstract: The present invention relates to a method of applying a hot melt adhesive to an absorbent article, such that the article has low autoadhesion, yet maintains excellent attachment properties during use in a consumer's undergarments. This is achieved by selecting the rheological properties of the adhesive and the mechanical properties of the substrate being coated. The adhesive is directly applied to a backsheet layer outer surface, wherein the adhesive has a viscosity of less than about 10,000 centipoise at a temperature of about 130 to about 177 degrees Celsius. The backsheet layer has a tensile strength of at least 5 Newtons per 25 millimeter width of material.Type: GrantFiled: March 30, 2000Date of Patent: September 2, 2003Assignee: McNeil-PPC Inc.Inventors: Michael Moscherosch, Joseph Michael Luizzi, Jr.

Patent number: 6391011Abstract: Disclosed is a sanitary napkin having flaps folded over the topsheet. This arrangement helps to maintain the topsheet in a sanitary condition and is more convenient for the wearer than a configuration having the flaps folded over the backsheet. The flaps may be maintained in this folded arrangement by a unitary release strip which bridges the flaps and covers any adhesive used to attach the flaps to the undergarment. If desired, the release paper may further wrap the longitudinal side margins of the sanitary napkin to additionally cover adhesive disposed on the central portion of the backsheet. If desired, the flaps may be folded over the topsheet, overlap each other and be adhesively joined to the other flap.Type: GrantFiled: May 8, 1995Date of Patent: May 21, 2002Assignee: The Procter & Gamble CompanyInventors: Elizabeth Jean Davis, Thomas Ward Osborn, III
