Abstract
A reusable, composite coaster for use with a beverage container is characterized by a base substrate of open cell foam material which is heat fusion and pressure bonded to a cover substrate of polymeric fabric material. The open weave of the polymeric fabric material permits moisture to drain into the open cell foam layer, while preventing the buildup of a partial vacuum between the bottom surface of a beverage container and the coaster surface. Moreover, the polymeric fabric cover substrate increases the tear resistance of the assembly, while the open cell foam layer increases the reservoir capacity of the composite assembly.
