ABSTRACT:
A transportable container for carrying refrigerated products in frozen (sub zero Fahrenheit) or refrigerated (for example, 40.degree. F.) temperatures includes a structural container having an insulated outer shell with an access doorway. The upper portion of the container includes a transverse perforated baffle and positioned above the baffle are a pair of spaced apart canisters containing liquid refrigerant (CO.sub.2, for example). A gas or liquid feeder tube penetrates each bottle and communicates with an on/off valve. A feeder tube can draw liquid to dispense for cooling, or it can release gas and pressure within the canister to boil the CO.sub.2. When CO.sub.2 reaches its boiling point, the canister, its bracket, and the cold plate reach very cold temperatures to cool the cargo area. The gas is released through copper tubing over the cold plate to act as a method for convection. A temperature regulator valve dispenses CO.sub.2 from the canisters through a header in order to maintain a desired temperature over a wide span of temperatures including, for example sub zero temperatures (-20.degree. F., for example) up to room temperature.
