Abstract:
1. A vacuum insulated door structure comprising: a first wall member having a first perimetrical edge, at least four outer sidewalls that extend substantially perpendicular from the first perimetrical edge and to a perimetrical lip, a barrier layer having a hermetic barrier film and a heat sealing layer, a first inner facing surface and a first outer facing surface; a second wall member having a second inner facing surface, a second outer facing surface, a second barrier layer having a hermetic barrier film and a heat sealing layer, and a second perimetrical edge coupled to the first wall member proximate the perimetrical lip, wherein the second wall member comprises at least four inner side walls defining a second wall opening distal from at least a portion of the second perimetrical edge, and wherein the at least four inner sidewalls extend from the second wall opening toward the first wall member to a back wall, wherein the at least four sidewalls and the back wall define a second wall offset; at least one tubular member having first and second conduit ends, an inner conduit surface and an outer conduit surface, wherein the first conduit end is coupled to a first wall conduit opening defined by the first wall member and the second conduit end is coupled to a second wall conduit opening defined by the second wall offset, and wherein the inner conduit surface provides a fluid communication between the first wall outer facing surface and the second wall outer facing surface, and wherein the first and second wall members and the at least one tubular member form a door structure; and a cavity insulation material disposed within a cavity volume defined by an interior volume of the door structure, wherein the cavity volume is hermetically sealed, wherein the cavity volume includes an at least partial vacuum.
