  • Patent number: 4550849
    Abstract: A thermoformable plastic commerical refuse container is rotationally molded with a pair of metal lifting sleeves in situ' molded into the container. The side walls of the container are designed to accept the metal sleeves internally of the container and to distribute the lifting stress over the wall. The container walls are outwardly projected above the sleeves so as to increase the available storage volume of the container. An improved box-shaped top flange design is used to tie the walls of the container together and to provide increased strength and rigidity.
