ABSTRACT:
A self-cooling fluid container for beverages includes a beverage chamber and a refrigerant chamber in a nested configuration. Release of the refrigerant effects cooling of the beverage as a result of conductive heat transfer between the expanding refrigerant and the beverage chamber. The refrigerant chamber is wholly self-contained and nests snugly within a recess formed in the beverage chamber, thereby providing enhanced wall thickness and strength for containing a pressurized refrigerant, as well as enhanced heat transfer between the beverage chamber and the refrigerant chamber.
