ABSTRACT:
There is provided a portable refrigerating unit to be used for chilling beverages, the same having an outer shell insulated on the inside and an inner shell for holding a beverage container in close fitting relationship therewith. The inner shell is fabricated of a highly thermoconductive material, such as aluminum. The close fitting relationship with the beverage container allows an efficient conductive heat transfer when the outer surface of the inner shell is subjected to an evaporating refrigerant gas directed thereon by an evaporator tube that is mounted between the outer and inner shells. Refrigerant gas is supplied to the evaporator tube by a disposable pressurized refrigerant gas container. An ejector is provided for ejecting the beverage container after chilling.
