ABSTRACT:
A cabinet structure having upstanding sidewalls defining vertical corners. The sidewalls include an inner liner, an outer shell, and foamed-in-place insulation between the liner and shell. A first breaker collar extends between the shell and liner across the insulation space. A second breaker collar extends between the shell and liner across the insulation space, with the breaker collars having spaced end portions at a corner of the cabinet. A collar corner element is installed across the space between the breaker collar ends at the corner and includes temporary locking structure for holding the corner element in place during the forming of the foamed-in-place insulation. The corner element further includes a locking wall extending into the insulation space so as to be embedded in the foamed-in-place insulation upon completion of the foaming operation. A number of different structures for effecting the temporary retention of the corner element in the cabinet structure during the foaming operation are disclosed.
