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.
Claims7
A composite coaster for use with a beverage container comprising a first substrate of open cell foam material and a second substrate of polymeric fabric material, the first substrate of open cell material being superposed onto the second substrate of polymeric fabric material, and being bonded thereto.
A composite coaster assembly comprising a first substrate of polymeric fabric material, a second substrate of polymeric fabric material and a third substrate of open cell polymeric foam material, said fabric substrates being superposed onto opposite sides of said open cell foam substrate and bonded thereto.
