Abstract
Resilient seal and retainer assemblies for the side edges of a swing door panel of a cargo container. Each assembly includes, in one embodiment, a resilient seal member and a relatively rigid retainer member, coextruded of polyvinyl chloride. The retainer member includes a channel part with a web and opposed flanges for receiving one of the side edges of the door panel and the retainer member also includes a base part extending from the web for supporting the resilient seal member which includes a convex, thinned-walled rim part and internal webs extending radially inwardly from the rim part to reinforce the rim part and to restore the rim part to a convex, undeflected condition when the rim part is disengaged from a sealing surface on a frame of the door panel. In an alternate embodiment, the seal member of each of the assemblies is provided with its own integral coextruded base part which may be slidably or snap-fitted into engagement with a separately formed retainer member.
