Abstract
An auxiliary box placed in an insulated chamber, vessel or container to produce a controlled temperature. The auxiliary box receives a coolant, such as dry ice (CO2), and is constructed to allow controlled escape of the coolant into the chamber, vessel or container at a predetermined rate thereby controlling and maintaining the temperature ranges in the chamber, vessel or container to be cooled at a substantial constant temperature.
Claims6
An auxiliary cooling box for positioning in a product receiving space in an insulated container for maintaining said space at a constant selected low temperature, a quantity of dry ice CO2 coolant in said cooling box, said cooling box including peripheral wall areas provided with different porosity characteristics to vary the flow of coolant into said product receiving space, and a closure for selective porosity areas in the peripheral wall of said cooling box to maintain a predetermined temperature in said product receiving space in said insulated container.
In combination with an insulated container having a product receiving space provided with a removable closure to provide access to said space, an auxiliary cooling box dimensioned to be placed in said space, a quantity of dry ice CO2 coolant in said auxiliary box, said auxiliary box having a porous wall area for discharging gaseous coolant into said space at a selective rate to lower the temperature in said product receiving space to a constant selected temperature for a predetermined time interval.
