ABSTRACT:
A refrigerated beverage mug is provided which includes a self-contained mechanical refrigeration unit which is powered by a power unit mounted onboard the beverage mug. The mechanical refrigeration unit is a closed loop system which is mounted to the beverage mug and includes a compressor, a condenser, an expansion flow passage and an evaporator. The condenser and the evaporator are integrally formed with the main body of the beverage mug. The compressor is mounted to the beverage mug for circulating a refrigerant through the condenser, the expansion flow passage and the evaporator. The power unit includes a chamber which contains a pressurized, expansible fluid such as liquid nitrogen, which is selectively released for passing through a pressure chamber of the compressor to power the compressor and the mechanical refrigeration unit. A manifold is integrally formed into the compressor housing for passing the expansible fluid from the compressor and across a portion of the condenser.
