Abstract

A defrosting device for use in a household or commercial environment to effectively defrost frozen food packages is described. The device consists of three major parts; a top shell, a bottom shell and a hinge mechanism connecting the top shell and the bottom shell to allow the top shell to rotate around the hinge to open and close relative to the bottom shell. To defrost a frozen food package, the defrosting device rests on a flat surface, such as on a countertop, and the frozen food package is sandwiched between the top shell and the bottom shell. Since resistance to heat transfer from the ambient, air and from the flat surface to the frozen food package is minimized through the paths along the top shell as well as the bottom shell, the defrosting device is able to effectively defrost frozen food packages.

Claims

1. A defrosting device resting on a significantly flat surface for use to defrost a frozen food package, comprising:

A top shell comprising a top side that is substantially exposed to ambient air, a bottom side, a hermetically sealed top cavity formed by said top side and said bottom side, and a liquid material significantly filling said top cavity;

wherein said bottom side comes into direct contact with said frozen food package that is positioned underneath said top shell;

A bottom shell comprising a bottom side that rests on said flat surface, a top side, a hermetically sealed bottom cavity formed by said bottom side and said top side, and a liquid material significantly filling said bottom cavity;

wherein said top side comes into direct contact with said frozen food package that rests on said top side of said bottom shell;

A hinge mechanism connecting said top shell and said bottom shell to allow said top shell to rotate around said hinge mechanism to open and close in relation to said bottom shell

2. A defrosting device as defined in claim 1, wherein said liquid material that fills said top cavity and said bottom cavity is preferably at least partially filled with at least one particulate material whose thermal conductivity is higher than that of said liquid material.

3. A defrosting device as defined in claim 1, wherein said top side of said top shell is preferably made of a substantially rigid and thermally conductive material.

4. A defrosting device as defined in claim 3, wherein said top side of said top shell includes at least one fin to increase surface area.

5. A defrosting device as defined in claim 1, wherein said bottom side of said top shell is preferably made of a durable and flexible material such that said bottom side of said top shell can significantly conform to the shape and contour of said frozen food package resting underneath said top shell.

6. A defrosting device as defined in claim 1, wherein said bottom side of said bottom shell is preferably made of a substantially rigid and thermally conductive material.

7. A defrosting device as defined in claim 6, wherein said bottom side of said bottom shell is substantially covered with a thermally conductive interface material to minimize thermal resistance between said bottom side of said bottom shell and said flat surface upon which said defrosting device rests.

8. A defrosting device as defined in claim 1, wherein said top side of said bottom shell is preferably made of a durable and flexible material such that said top side of said bottom shell can significantly conform to the shape and contour of said frozen food package resting on top of said bottom shell.
