Picnic Cooler with Internal Compartment for Cooling with Liquid Nitrogen

Abstract

A picnic cooler with a cooling mechanism based on the use of liquid nitrogen, that comprises four sides, bottom, cover, an internal compartment, an adapter. The internal compartment is integrated into one or more sides of the cooler and is made of a material that cools rapidly upon contact with the quick nitrogen. The internal compartment has one or more ventilation opening. The connector is designed to enable the attaching of an external canister of liquid nitrogen so as to enable introduction of liquid nitrogen from the canister into the internal compartment through the connector.

What is claimed is: 
     
         1 . A picnic cooler with a cooling mechanism based on liquid nitrogen, that comprises four sides, a bottom, a cover, and internal compartment, and an adapter; wherein the internal compartment is integrated into one or more sides of the cooler and is made of a material that becomes cold upon contact with liquid nitrogen; wherein the internal compartment has one or more ventilation openings; wherein the adapter is designed to enable the user to connect an external canister of liquid nitrogen so that liquid nitrogen may be introduced from said canister into the internal compartment through said adapter. 
     
     
         2 . A picnic cooler with an independent cooling mechanism based on liquid nitrogen that comprises a dedicated compartment ( 101 ) for a nitrogen canister in which a nitrogen canister ( 102 ) may be installed, an electric spigot ( 103 ), a cooling means ( 104 ), an aperture for introducing nitrogen into the cooler ( 105 ), an aperture for releasing nitrogen from the cooler ( 106 ), an electric power source ( 107 ), and a command and control system ( 108 ); wherein the designated compartment is equipped with an adaptor ( 1010 ) to which the opening of the nitrogen canister is attached; wherein the aperture for releasing nitrogen from the cooler ( 106 ) is equipped with a unidirectional valve ( 1060 ); and whereby the command and control system ( 108 ) is equipped with a controller ( 1081 ) and a temperature sensor ( 1082 ).
