ABSTRACT:
A refrigerator cabinet includes a storage compartment defined by encased walls forming a peripheral edge surface surrounding the access opening. A door is hingedly mounted adjacent one edge and includes a resilient sealing gasket to seal the opening. A resilient flap is mounted on the inner panels of the walls or on the opposed liner panel of the door so that an auxiliary seal is formed separate from the gasket. An extended dead air space is provided between the flap, gasket and the opposed panels so that heat transfer from the area of the gasket into the compartment is substantially eliminated. The elongated body of the flap is approximately 70 Shore A Durometer hardness, and the base is approximately 70 Shore D Durometer hardness of a suitable plastic, such as polyvinylchloride. In one embodiment, the cross-section of the body takes the form of a bulb with a substantially semicircular cross-section, and in another embodiment, the body takes the form of a spike in cross-section with a convergent 5.degree. angle from the base. Corner sealing inserts attach to the adjacent ends of the wipers.
