  • Patent number: 7293848
    Abstract: A refrigerator cabinet includes a shell having first and second laterally spaced, upstanding side walls that are interconnected by a top wall, each of the walls includes an in-turned front edge portion defining a liner receiving cavity. The shell further includes a mullion bar, which partitions the shell into first and second liner cavities, and a base member. Both the mullion bar and base member have respective liner receiving portions. With this arrangement, first and second liners are adapted to be inserted into their respective cavities and flexed such that three sides are inserted into the liner receiving cavities, while the remaining side is positioned against a land of the mullion bar or base member. Once in place, the liners are secured through a mullion bar cover and a base member cover. This construction combines the benefits of a front-load process with that of a flex-load process, lowering assembly time without the need to reinforce the liner.
