Abstract
Gasket for refrigerator cabinets of the kind including a soft bellows-type portion used for sealing the area between the cabinet and the door and extending from a base portion able to match the outer door and/or inner door of the refrigerator cabinet. The base portion is substantially rigid and has at one end, a sealing portion made of substantially soft material extending toward the inner door. The soft material portion has good flexible and spring back features when exposed to refrigerator and freezer temperatures. These features make the gasket able to further seal, preferably by compression, the space located between the cabinet and inner door in a more internal area of the refrigerator cabinet. Furthermore, the soft sealing portion is independent and free from constraints with respect to the soft bellows-type portion.
