ABSTRACT:
The present invention comprises an apparatus for cooling liquid held in a vessel having an externally extending handle. The apparatus comprises a double-walled container having an inner wall and an outer wall radially spaced apart. The inner wall and outer wall are sealingly attached to a generally flat base member. Each of the inner and outer walls extend generally arcuately about the base member and defines a slot extending substantially perpendicular from the base member. The ends of the inner wall are sealingly connected to the ends of the outer wall adjacent the slot and edges of the inner and outer walls distal from the base member are sealingly attached one to the other for defining a closed space between the inner and outer walls. A refrigerant coolant is disposed in the closed space for maintaining the container at a predeterminately cool temperature for a determinable time interval. The vessel is removably positionable in the container with the handle extending through the slot.
