Abstract
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.
Claims28
A waste container comprising
- a generally cylindrical body wall;
- a bottom wall closing a lower end of the body wall;
- a lip extending radially outward from an upper end of the body wall;
- and
- at least one protrusion extending outward from the container spaced below the lip, the at least one protrusion integrally molded with the body wall, the at least one protrusion spaced below the lip to define a gripping area therebetween for engagement by a gripper for lifting and inverting the waste container, the at least one protrusion protruding outwardly farther than an outer surface of the gripping area wherein the body wall includes a plurality of vertical inner and outer splines, wherein the at least one protrusion protrudes outwardly from at least one of the outer splines and the outer splines are non-parallel.
A molded plastic waste container comprising
- a generally cylindrical body wall;
- a bottom wall closing a lower end of the body wall;
- an upper radial protrusion extending radially outward from an upper end of the body wall;
- and
- a plurality of bosses integrally molded with the body wall and protruding outward from the body wall between the upper radial protrusion and the bottom wall wherein the plurality of bosses are spaced below the upper radial protrusion to define a gripping area;
- and
- further including grippers engaging the body wall entirely between the upper radial protrusion and the plurality of bosses, wherein the plurality of bosses each have a generally straight edge defining the gripping area between the generally straight edges of the plurality of bosses and the upper radial protrusion.
A molded plastic waste container comprising
- a generally cylindrical body wall having a plurality of vertically extending splines;
- a bottom wall closing a lower end of the body wall;
- a lip extending circumferentially about an upper end of the body wall;
- a pair of handles protruding outwardly from the body wall;
- and
- a plurality of bosses protruding outward from the body wall between the lip and the bottom wall, the plurality of bosses spaced below the lip to define a gripping area therebetween for engagement by a gripper for lifting and inverting the waste container wherein the plurality of bosses includes:
- a first plurality of generally circular bosses arranged below a plurality of triangular bosses;
- and
- a second plurality of generally circular bosses are arranged above the plurality of triangular bosses.
A molded plastic waste container comprising
- a generally cylindrical body wall having a plurality of vertically extending splines;
- a bottom wall closing a lower end of die body wall;
- a lip extending circumferentially about an upper end of the body wall;
- a pair of handles protruding outwardly from the body wall;
- and
- a plurality of generally triangular bosses and a plurality of generally circular bosses protruding outward from the body wall between the lip mid the bottom wall, the plurality of triangular bosses and the plurality of generally circular bosses spaced below the lip to define a gripping area therebetween for engagement by a gripper for lifting and inverting the waste container, the generally circular bosses each substantially smaller than each of the plurality of triangular bosses, wherein a first portion of the plurality of circular bosses are arranged below the plurality of triangular bosses and a second portion of the plurality of circular bosses are arranged above the plurality of triangular bosses, wherein the waste container does not have wheels.
