Abstract
A refuse container of the type adapted to be lifted during an emptying cycle from an upright position by opposed retaining arms of a mechanical dumping unit, emptied into a refuse vehicle and lowered back to the upright position. The refuse container comprises a bottom, with side walls connected to the bottom on one end and defining an open top on the other end. The side walls include first and second spaced-apart shoulders which define a narrowed waist formed in the walls around the periphery of the refuse container to receive the retaining arms and lock the refuse container against movement relative to the retaining arms during both the lifting and lowering movements of the emptying cycle.
