ABSTRACT:
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 surface of a foam plug by the pressure produced during foaming of the foamed thermal insulation material. This results in each corner having a central portion with a convex cross section and an outer portion surrounding the central portion and concave in cross section whereby it does not appear to be crinkled.
