Abstract: A rotationally molded container rim and method for fabrication thereof. The inventive method includes rotationally molding a container while at the same time integrally molding a circumferential rim having an enclosed interior void. Molten plastic and unmelted particles flow from a primary portion of the mold through a gap of uniform width into a secondary mold portion to form the rim. During molding, air is vented from the enclosed void to ambient air outside the mold through a vent opening. The vent opening preferably includes a hollow tube. The rotationally molded container rim that is formed according to the inventive method preferably includes walls that form an enclosed polygonal section. The walls enclose the interior void and at least one vent opening leads from the interior of the rim to the outside of the container.

Abstract: A new molding composition used, for example, in a rotationally-molded thermoplastic refuse container of the type having a hollow handle integrally-molded with a refuse carrying compartment of the container, the improvement which includes a wall integrally-formed with the refuse container and sealingly enclosing the hollow handle from communication with the refuse-carrying compartment of the container for providing greater strength to the container and preventing refuse from lodging in the hollow handles.
