ABSTRACT:
A refrigerator cabinet includes a storage compartment defined by encased walls including inner metal panels and corresponding breaker panels 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 formed on the breaker panel so that an auxiliary seal is formed separate from the gasket against the liner panel of the door upon closing. 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 of a suitable plastic, such as polyvinylchloride. In the preferred embodiment, the cross-section of the body takes the form of a spike in cross-section with a convergent 5.degree. angle from the base. The flaps extend at included angles of approximately 45.degree. to the panels.
