A waste container provides at least one protrusion spaced below a lip extending radially outwardly from an upper edge of the waste container. The at least one protrusion is spaced below the lip to permit a gripper from an automatic lifter to grasp the waste container between the at least one protrusion and the upper lip. The at least one protrusion may be a plurality of triangular shaped bosses formed midway between the upper edge and lower edge of the waste container. Alternatively, the at least one protrusion may be a base portion which extends radially outwardly at a lower edge of the waste container. The at least one protrusion prevents the waste container from slipping completely through the grippers while the waste container is inverted while emptying the contents into a truck.
