Abstract: A method of manufacturing a fabric mesh reinforced monolithic thermoplastic membrane. The open mesh fabric is drawn into the gap between two calender rollers of a membrane extruder, a molten first thermoplastic material is extruded into the throat of the gap between the first roller and the first side of the fabric mesh, while a second molten thermoplastic material is simultaneously extruded into the throat of the gap between the second roller and the second side of the fabric mesh. The composite material is then drawn through the gap between the first and second rollers to force the molten first and second thermoplastic materials into and through the open mesh of the fabric to fuse and bond the molten first and second thermoplastic materials in and about the fabric mesh to form the fabric mesh reinforced monolithic thermoplastic membrane.

Abstract: An improved applicator for medicinal, therapeutic, pharmaceutical, and/or cosmetic preparations comprising an applicator head having a foam applicator head, a flexible tubular reservoir for storing the preparation, and a cap to seal off the applicator end of the applicator head. The foam having one or more slits which form communication passageways between the reservoir and the applicator head and which are compressed by the cap to prevent migration of air from the exterior into the reservoir and passage of preparation from the reservoir to the applicator head when the cap is seated on the applicator head.
