A portable apparatus for sequentially cooling a pluraity of containers of beverages and the like includes a portable housing containing the following devices. An evaporator circulates a refrigerant therethrough and defines a receptacle for receiving a container to be cooled in close heat-conducting relation thereto. A supply tank initially contains pressurized refrigerant sufficient for cooling a plurality of containers. A conduit transmits the pressurized refrigerant from the supply tank to the evaporator. A valve forms a part of the conduit and includes devices for actuating the valve to allow the flow of pressurized refrigerant from the supply tank and devices responsive to the flow of a predetermined quantity of refrigerant from the supply tank sufficient for cooling a single container for deactuating the valve device to stop the flow of refrigerant from the supply tank and provide the predetermined quantity of refrigerant to the evaporator for cooling the container received in the receptacle.

A portable, open cycle, refrigeration apparatus for sequentially cooling containers of beverages and the like and having a capacity for a plurality of sequential cooling operations comprising: a portable housing; evaporator means carried by said housing for receivIng and circulating a refrigerant therethrough during each cooling operation and including venting means for releasing the refrigerant after circulation to the atmosphere and defining therewithin a receptacle for recieving a container to be cooled in close heat-conducting relation thereto; a refrigerant supply tank carried by said housing for initialy containing a supply of a pressurized refrigerant sufficient for a plurality of sequential cooling operations; conduit means carried by said housing and communicating with said evaporator means and said refrigerant supply tank for transmitting the pressurized refrigerant from said tank to said evaporator means; and valve means carried by said housing and forming a part of said conduit means and including means for actuating said valve means to allow the flow of pressurized refrigerant from said refrigerant supply tank and pressure responsive means responsive to the flow of a predetermined quantity of less than the total supply of refrigerant from said supply tank sufficient for a single cooling operation for deactuating said valve means to stop the flow of refrigerant from said supply tank and provide the predetermined quantity of refrigerant to said evaporator for a single cooling operation.
