ABSTRACT:
A multi-layer insulator for a beverage container which includes an externally threaded base and a main sleeve extending upwardly from the base and having a collapsible side wall. The main sleeve comprises an exterior fabric layer, an interior fabric or neoprene layer, and an intermediate insulation layer. The lid for the insulator has internal threads for screwing the lid over the externally threaded base assembly, such that when the insulator is not in use the main sleeve is collapsible into the base with the lid screwed on the base to enclose the sleeve. When the insulator is in use, the lid is unscrewed from the base, the main sleeve is extended to receive the container and the lid is inverted and screwed to the base from the bottom thereof, functioning essentially as a coaster. The multi-layer insulator also has a closure band at the upper end of the main sleeve, with the band being adjustable to accept beverage containers of varying diameter.
