  • Patent number: 4914341
    Abstract: A refrigerator cabinet has a metal outer shell with a one-piece, thermoplastic inner liner having a peripheral flange received in a groove formed in the outer shell. Foamed-in-place insulation is used between the liner and the shell and the cabinet has a partition separating the interior of the liner into an upper freezer and lower fresh food compartment. The partition is supported by inwardly projecting ribs formed integrally with the liner extending around the back and two sides and terminating adjacent the peripheral flange. The peripheral flange in the area of the partition has an offset portion extending away from the front face, forming a curved portion which cooperates with the projecting ribs in providing vertical compliance of the liner during thermal expansion and contraction to reduce the possibility of stress cracking.
