Abstract: An appliance door particularly suited for use as a refrigerator or freezer door includes a hollow, blow molded door slab, and a food storage shell or casing projecting from one wall of the slab. The parts forming the shell are prepared in a first step, e.g., by blow molding, and then are removably mounted as inserts in registering recesses formed in the bottom of the cavity of one of two plates or sections forming the mold for the door slab. The two mold sections are then closed over a tubular, plastic parison which is then inflated to form in the mold the hollow door slab, portions of one wall of which mold over and around a series of male projections which extend into the mold cavity from the mold inserts, thus causing the shell to be molded to and to project from the slab upon subsequent opening of the mold sections and removal of the slab therefrom.

Abstract: Each of two identical hinge plates has projecting from one longitudinal side edge thereof four, spaced, coaxially aligned barrels, two of which have therethrough coaxial bores, and each of the other two of which has a reduced-diameter cylindrical pin projecting from one end thereof. The four barrels of each plate are arranged so that the two barrels containing bores are consecutive or adjacent to each other, and the two barrels bearing the cylindrical pins are adjacent to each other. A hinge is assembled by inserting the pins of each hinge plate coaxially and rotatably into the barrel bores in the other plate. Thereafter a locking element may be inserted between a pair of adjacent barrels to prevent accidental disengagement of the cylindrical pins from the barrel bores.
