Abstract
A beverage container insulator has an outer, vinyl coated, flexible plastic foam sleeve member open at both ends and having inwardly curved ends with re-entrant edges. A substantially rigid cup-shaped plastic inner liner, shorter than the sleeve member, is disposed in the sleeve member with an interference fit between the liner and sleeve member. A top edge of the liner has a radially projecting flange to add rigidity and aid in retaining the liner within the sleeve member. The liner has a vacuum break opening in a transverse bottom wall to provide for ease of insertion, retention and removal of a beverage container with respect to the insulator.
