ABSTRACT:
A plastic blow molded containr and lid combination wherein the double-walled lid is screwed to the top of the container and a parallel pair of horizontal recesses are provided on opposite sides of the container wall for receiving forks of a forklift for lifting and otherwise manipulating the container with a conventional forklift. The bottom of the container is also provided with forklift access recesses for lifting and manipulating the container from the bottom with a conventional forklift. The underside of the lid is provided with a protrusion for engaging the upper end of a salvage drum within the container to confine the drum between the top and bottom of the container. An override lid lock mechanism is provided to prevent the lid from accidentally unthreading itself. In addition, central portions of the bottom of the container are recessed upwardly with respect to perimeter portions of the container bottom so that the container in an empty condition will stably rest on a surface without easily tipping. The container and lid are blow molded of high density/high molecular weight thermoplastic such as polyethylene.
