Patent number: 6277458Abstract: The present invention relates to a laminated structure comprising an adhesive coated strip which is mounted upon a release strip wherein the release strip includes a partible break and wherein the release strip farther includes a tab. Deflection of the release strip tab in a direction away from the adhesive coated strip generates a partial separation of the release strip tab from the general plane of the release strip at the partible break causing an edge of the adhesive coated strip to be exposed for grasping by the user. The present invention also relates to methods for removal of an adhesive coated strip from the release strip.Type: GrantFiled: March 15, 1999Date of Patent: August 21, 2001Assignee: The Procter & Gamble CompanyInventors: Robert Stanley Dirksing, Paul Albert Sagel
