Abstract

See full text

An outer structure for a refrigerated food storage apparatus includes an outer shell forming a visible exterior of the apparatus; and an inner liner made of molded plastic and coupled to the outer shell, to form an inter-panel space to be filled with a body of foam insulation. The inner liner includes bosses of a predetermined length, integrally formed with the inner liner at regular intervals and extending toward the outer shell, to support and maintain a constant spacing between the outer shell and inner liner; a foam-injection inlet for injecting foam; and vents for exhausting air and gases generated during a foam injection process. A reactive foam completely fills the inter-panel space, to form a consistent body of insulation. The force of the reactive foam filling the inter-panel space closes a hinged first flap for covering the foam-injection inlet and a plurality of hinged second flaps for covering the vents. The foam-injection inlet is formed in the bottom of a container centrally installed on the inner liner, to communicate with the inter-panel space.
