Abstract
Abstract A refrigerator cabinet structure is provided in which a closedcell foamed seal is utilized as a seal between the rear panel and outer wrapper of the refrigerator cabinet at the rear and an open-cell foamed seal is utilized between the outer wrapper and inner liner at the front of the refrigerator cabinet. The space between the inner liner, outer wrapper and rear panel is then filled with a conventional foamed plastic insulating material with the open cell foam seal at the front of the refrigerator cabinet permitting the escape of air as the foamed plastic expands into the space between the outer wrapper, inner liner and rear panel.
