ABSTRACT:
A self-cooling fluid container includes a fluid chamber for containing the fluid-to-be-cooled. A refrigerant chamber, containing a pressurized refrigerant, is affixed to the base of the fluid chamber and extends at least partially into the fluid chamber. The interior region of the refrigerant chamber is fluidicly isolated from and thermally coupled to the interior region of the fluid chamber. A refrigerant dispersal assembly defines a vented dispersal region including a portion adjacent to the refrigerant chamber and separated from the interior of that chamber by a perforatable wall. A cooling activator is adapted to selectively form a fluidic path from the interior of the refrigerant chamber to the dispersal region through the perforatable wall, permitting release and expansion of the pressurized refrigerant.
