ABSTRACT:
A cooling receptacle for individual beverage containers comprises a double-walled cylinder open at the top and closed at its base. The base is hollow and contains a high density granular material. The inner cylindrical wall is formed of a material having a higher thermal conductivity than the material of the outer cylindrical wall. An annular resilient retaining element is secured to the inner surface of the inner cylindrical wall. A detachable closure disc formed of a material having a relatively low thermal conductivity and having a central opening exposing the cavity of the receptacle is adapted to seal the cooling chamber between the inner and outer cylindrical walls of the receptacle.
