Estimating the term…
An insulated door for use in a refrigerator having an ice and water through the door dispenser is made by attaching a liner for housing the dispenser on the rear face of the door in line with a front opening. The liner is secured to the door as are the hinge bearings and a tube extends between the liner and the lower hinge bearing for conducting electrical wires and a water tube. The only opening in the liner is at a point to receive ice cubes from the dispenser in the refrigerator and this opening is covered prior to foaming. The door is placed in a foaming fixture which completely enclosed and supports the door and the liner and foam is injected so that the foam, when expanded and hardened, completely covers the rear face of the door. After the door is removed from the foaming fixture, the thin layer of foam at the inlet opening is cut away and the door is completed by adding the liner and the gaskets and other hardware as well as the dispensing unit itself.
An insulated door for a refrigerator, said door having a rectangular front face, said door having a front panel of sheet material forming the rectangular front face of the door, said panel having front and rear sides and having inturned edges along each side forming the top, bottom and sides of the door, each of said edges terminating in an inturned lip extending in a plane parallel to said front face, an opening in said front face, a dispenser liner secured in abutting relation to the rear side of said front panel and extending completely over said opening, fastener means extending through said front face clamp said liner in place, said liner having an inlet opening at a rear of said door, said liner extending rearwardly beyond said inturned lips, and a layer of rigid insulating foam in contact with the rear side of said front panel said inturned edges, said inturned lips and said liner, said foam layer being unbroken and uninterrupted except for an opening at said inlet opening, said opening in said foam layer being slightly larger than said inlet opening.
