Abstract
A new Portable Food Refrigeration System for facilitating cooling of food when a refrigerator is unavailable thereby preventing the food from melting and becoming unappealing. The inventive device includes an outer pan formed to receive a frozen gel pack on the bottom surface, and an inner pan removably positioned within the outer pan juxtaposed the frozen gel pack where the inner pan creates a seal with the outer pan preventing the escape of cooled air from between the pans.
Claims6
A Portable Food Refrigeration System comprising:
- an outer pan constructed from a rigid insulating material including at least one handle secured to the upper exterior portion;
- a gel pack removably positioned on the interior bottom surface which is freezable;
- and
- an inner pan formed to a shape similar to the outer pan for retaining food and including at least one handle secured to the upper exterior portion, said inner pan being slidably positionable within in the interior of the outer pan to produce a nested relationship between said inner and outer pans;
- wherein one of said pans has a sealing protrusion located substantially adjacent to and along the upper edge of said one pan and the other of said pans has a sealing groove located substantially adjacent to and along the upper edge of said other pan such that when said pans are placed in a nested relationship said sealing groove and said sealing protrusion are moved into a mated condition, wherein the mated condition of said sealing protrusion and said sealing groove forms a substantially air tight barrier and resists movement of said inner pan out of the nested relationship with said outer pan.
