Abstract

Official abstract text for this publication.

A refrigerator includes an inner liner, an outer wrapper and a trim breaker that extends between the inner liner and the outer wrapper to define an insulated structural cabinet. The trim breaker includes a plurality of gas-blocking flakes, wherein each gas-blocking flake includes a longitudinal axis that extends substantially parallel with an elongated surface of the respective gas-blocking flake. The longitudinal axis and the elongated surface of each corresponding gas-blocking flake is oriented to be substantially parallel with a portion of an outer surface of the trim breaker located near the respective gas-blocking flake.

First claim

Opening claim text (preview).

What is claimed is: 1. A refrigerator comprising: an inner liner; an outer wrapper; and a trim breaker that extends between the inner liner and the outer wrapper to define an insulated structural cabinet, wherein: the trim breaker includes a plurality of gas-blocking flakes that are disposed throughout the trim breaker, wherein each gas-blocking flake includes a longitudinal axis that extends substantially parallel with an elongated surface of the respective gas-blocking flake; and wherein the longitudinal axis and the elongated surface of each corresponding gas-blocking flake is oriented to be substantially parallel with a portion of an outer surface of the trim breaker located near the respective gas-blocking flake. 2. The refrigerator of claim 1 , wherein the plurality of gas-blocking flakes are made of at least one of mica particles and glass particles. 3. The refrigerator of claim 1 , wherein the trim breaker includes a substantially homogenous mixture formed from a base material and the plurality of gas-blocking flakes. 4. The refrigerator of claim 3 , wherein the substantially homogenous mixture includes an amount of gas-blocking flakes that is in a range of from approximately 10 percent to 40 percent by volume of the substantially homogenous mixture. 5. The refrigerator of claim 3 , wherein the base material includes a polymer material. 6. The refrigerator of claim 3 , wherein the base material includes at least one of a polymer network and a silica-based material. 7. The refrigerator of claim 1 , wherein the plurality of gas-blocking flakes include a range of sizes measured along the longitudinal axis, wherein the range of sizes is from approximately 5 microns to approximately 800 microns. 8. The refrigerator of claim 1 , wherein the trim breaker partially defines an interior cavity of the insulated structural cabinet that is maintained at an at least partial vacuum. 9. The refrigerator of claim 1 , wherein an aspect ratio of length to thickness for each respective gas-blocking flake is in a range of from approximately 100 to approximately 5,000. 10. The refrigerator of claim 1 , wherein the trim breaker includes an epoxy coating that is disposed on the outer surface of the trim breaker.
