Abstract
A retainer for use in a refrigerator door or the like in which insulative material is foamed during a foaming process in the interior of the door. The door or the like is formed of separate shell and pan portions which have edges which are inserted in respective opposing slots of the retainer. Fins are provided on surfaces of the retainer opposite the shell and pan portion edges to form a seal therewith which retains the insulative material within the interior of the door during the foaming process. The fins are made of a material which is softer and more flexible than the material of the remainder of the retainer and the fins eliminate a need to clean foamed insulative material which leaks through the seams between the retainer and the shell and pan portions during the foaming process from the exterior surfaces of the shell and pan portions.
