ABSTRACT:
A drinking container having a removable, freezable member. The drinking container has a cylindrical inner receptacle and a surrounding cylindrical outer receptacle. An annular chamber is formed between the inner and outer receptacles. A refrigerant member comprising a plastic envelope containing a freezable gel is dimensioned to fit into the annular chamber, and is readily removable therefrom. A cap engages the drinking container to retain the refrigerant member once placed in the annular chamber. The refrigerant member is preferably an annular sleeve which slips between the inner and outer receptacles, and folds flat for storage and freezing. The inner receptacle projects above the outer receptacle so that the user is obliged to engage only one wall with the mouth and lips, thereby enjoying comfortable drinking, rather than being obliged to span the combined thickness of the inner and outer receptacle walls together with the refrigerant member when drinking. Optionally, the drinking container has an external handle for grasping.
