Abstract: A heavy-duty, wear resistent, blow-molded plastic wheel comprising first and second integrally-formed wheel sides defined by alternating axially spaced-apart and joined side segments. A solid center core portion surrounds a central axle bore. The wheel also includes an integrally-formed, axially-extending tread, and molded, integrally-formed axle bore support means in the first and second wheel sides radially-outwardly adjacent of the axle bore and diagonally extending between the first and the second wheel sides to provide enhanced support to the axle bore.

Abstract: A heavy-duty, wear resistent, blow-molded plastic wheel comprising a circular web defining a central axle bore, an integrally-formed radially-extending peripheral side wall, and an integrally-formed, axially-extending tread, the side wall having a width no greater than one-fourth the width of the tread. A roll-out type, plastic waste container having a waste-receiving container body, a handle, a lifting bar and wheel mounts is provided in combination with a heavy-duty, wear resistant, blow-molded plastic wheel as described above mounted on the wheel mounts.

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.
