Abstract

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.
