A hinged door panel for refrigerators and freezers includes a rectangular shell having hinge bearing members mounted on each corner. Each hinge bearing defines a generally cylindrical opening proportioned to receive a hinge pin of a hinge mounted on the main cabinet of the refrigerator or freezer. The inner walls of the hinge pins are formed with a plurality of vent openings which allow gases to escape during the foaming of the insulation. The vent passages are sized so that they freely pass the gases and air contained within the cavity during the foaming but prevent insulating material from entering the hinge pin passage.

An insulated hinge panel for thermal cabinets comprising a polygonal shell having corners and defining at least part of a cavity, hinge bearings mounted in said shell adjacent to said corners, said hinge bearings extending into said cavity and defining a generally cylindrical passage adapted to receive and journal a hinge pin, said cylindrical passage being open at an outer end exterior of said shell and substantially closed at its inner end by an inner end wall, and insulation foamed in place filling said cavity including said corners, said hinge bearings providing at least one vent opening through which gases within said cavity are vented while said insulation is foamed so that said foam substantially fills said corners, said at least one vent opening being sized and shaped to allow gases to vent while preventing said foam insulation from entering said cylindrical passage.
