A refrigerator liner of a vacuum formed plastic with a thickness of about 0.007″to 0.050″has each corner formed without crinkling when thermal insulation material is foamed against the outer surface of the liner. The non-crinkling of each corner of the refrigerator liner is accomplished through forming each of the corners with a flat surface having its periphery as a circle during vacuum forming of the refrigerator liner rather than with a spherical radius. This enables the flat surface to be placed in tension when moved against a corresponding flat surf...
A refrigerator cabinet including a relatively thin liner of vacuum formed plastic material having a thickness no greater than about 0.050 inch; a casing disposed in spaced relationship to and surrounding said liner; and foamed-in-place thermal insulation material substantially completely filling the space between said liner and said casing and formed by foaming of a liquid foam supplied between said liner and said casing, said insulation material adhering to said liner and casing during foaming of the liquid foam; said liner including: a bottom wall; a t...
