Patent number: 5733275Abstract: Absorbent products having integral belt means for retaining the absorbent product in a position to absorb body fluids are disclosed. In a preferred embodiment, a napkin is provided wherein straps are cut from the material of the napkin. These straps are then tied around the body of the user when the napkin is applied. The straps are flexible enough to allow them easily to be tied to each other on the side. The straps may or may not be retained by the waistband of an undergarment. Alternatively, a second embodiment is provided wherein long flap-like straps extend longitudinally away from the transverse ends of the absorbent product. These straps are then engaged by the elastic waistband on an undergarment, to retain the napkin in place. Methods of manufacturing absorbent products are also disclosed.Type: GrantFiled: October 22, 1996Date of Patent: March 31, 1998Assignee: McNeil-PPC, Inc.Inventors: Martha Davis, Daniel Formosa, Jeannie Gerth, Patricia A.

Patent number: 5453296Abstract: A method of making an absorbent product in which pressure sensitive adhesive is used to attach the product to a user's undergarment. The product does not require release paper to protect the adhesive from unintended contact prior to use. The product is made by forming depressions in a fluid impervious barrier so as to create raised areas in the barrier that protect the adhesive. The depressions may be formed in the garment facing surface of the barrier and the adhesive applied within the depressions so that the raised areas adjacent the depressions protect the adhesive. Alternatively, the depressions may be formed in the surface of the barrier opposite the garment facing surface so as to create raised areas in the garment facing surface and the adhesive applied adjacent the raised areas.Type: GrantFiled: May 4, 1993Date of Patent: September 26, 1995Assignee: McNeil-PPC, Inc.Inventors: Nels J. Lauritzen, John T. Ulman
