Abstract: A structural foam partition formed by mating identical thin wall panel member halves obtained from the same mold. Panel member halves having molded-in fasteners for mating the panels, molded-in ribs for increasing structural rigidity, and molded-in means to join assembled partitions into restroom enclosures. Alternatively, a structural foam partition with molded-in corrugations to increase structural rigidity.

Abstract: A shopping cart having a basket mounted on a wheeled base. The basket comprises a main body member which is molded in one piece from plastics material and defines the bottom, front and side walls of the basket. A one-piece gate molded of plastics material is hingedly mounted on the body member and comprises the rear wall of the basket. The gate includes an integral handle which extends between and is rotatably supported on the side walls for both hingedly mounting the gate and for structurally connecting the side walls together. A collapsible baby seat assembly, which is preferably formed of plastics material in a single molding operation, is hingedly and slidably supported on the gate for movement between collapsed and non-collapsed positions. The base is also formed by a one-piece frame which is molded from plastics material, which frame has wheels mounted thereon for rolling engagement with a support surface.
