Abstract
An insulating holder for a beverage container has a cylindrical or frusto-conical sleeve having a lower end, an open upper end, an inner surface and an outer surface. The sleeve is made of a resilient elastomer having heat-sensitive tackiness, for example a thermoplastic elastomer such as thermoplastic polyurethane and/or polyurea.
Claims5
A reusable insulating holder for a beverage container suitable for a further said use comprising:
- a sleeve, of a cylindrical or frusto-conical shape, having an open lower end, an open upper end, and inner and outer surfaces;
- wherein the material of the sleeve is a resilient thermoplastic elastomer exhibiting a heat-sensitive tackiness in response to the heat of the beverage and whereas the presence of said heat results in tackiness on said inner and outer surfaces and whereas the absence of said heat eliminates said tackiness;
- wherein the sleeve is removable and reusable for a further said use;
- wherein the thermoplastic elastomer is a multi-block polymer;
- and
- wherein the sleeve is a molded, seamless monolithic structure.
