Abstract: Sealing structure for providing a seal between the perimeter of a door and a surrounding structure such as a door frame. The sealing structure is preferably formed as a tri-part extrudate and is particularly useful in providing a seal for a structure (e.g., a refrigerator, freezer, walk-in freezer, etc.) where it is desirable to obtain a hermetic and/or thermal seal.

Abstract: A honeycomb door seal for resiliently sealing a door to a surrounding structure has a semi-rigid base and a plurality of flexible enclosures. A central enclosure, capable of abutting a door, has an outer surface which is connected to a back side member of the seal through a plurality of ribs. A plurality of ribs generally form a common junction at the back side of the structure with each rib extending forwardly at an acute angle with respect to the door contact surface, i.e., the plane of the door. The remaining enclosures are arranged and shaped to provide good recovery and resiliency of the door seal. The seal can be made out of a flexible polymer such as a thermoplastic elastomer or a thermoplastic olefin.
