Abstract:

A portable ice chest (100) used for maintaining its contents in a cooled or frozen state for an extended period of time. The ice chest includes an insulated cover (300) with an inner compartment (315) and an insulated container (200) with a bottom compartment (270). The cover is adapted to fit airtight upon the top opening (245) of the container. To maintain the contents of the ice chest in a frozen state, a refrigerant coolant such as dry ice is placed in the inner compartment only. To maintain the contents of the ice chest in a refrigerated state, a refrigerant coolant such as dry ice is placed in the bottom compartment only. Additionally, when no dry ice is placed in either compartments, the present invention can be used as a regular ice chest.
