Abstract
A container and trolley system comprises a container that has a base and a sidewall that form a cavity and a trolley that comprises a trolley base and a plurality of wheels. The trolley base may include a container receiver that has a bottom surface that supports the container and sidewall surface. A projection may extend from the sidewall surface that has a proximal end at the sidewall surface and a distal end that extends toward a central region of the container receiver. The projection may engage the container to help secure the container to the trolley.
Claims20
A trolley configured to secure a container comprising:
- a trolley body comprising a side structure having a lower end and an upper end, an upper surface extending from the upper end of the side structure, and a lower surface opposite the upper surface, wherein the upper surface comprises a container receiver;
- wherein the container receiver includes a bottom surface spaced below the upper surface and a sidewall surface extending between the upper surface and the bottom surface;
- wherein the sidewall surface includes a first projection;
- wherein the first projection has a proximal end and a distal end opposite the proximal end, wherein the proximal end is connected to the sidewall surface and the distal end is located a first predetermined distance from the sidewall surface in a direction toward a central region of the container receiver;
- and
- a plurality of wheel assemblies connected to a plurality of wheel receivers connected to the lower surface of the trolley body.
A container and trolley system comprising:
- the container comprising a base and a sidewall extending upward from the base forming a cavity with an opening at a top end of the sidewall;
- and
- a trolley comprising:
- a trolley body comprising a side structure having a lower end and an upper end, an upper surface extending from the upper end of the side structure, and a lower surface opposite the upper surface, wherein the upper surface comprises a container receiver;
- wherein the container receiver includes a bottom surface spaced below the upper surface and a sidewall surface extending between the upper surface and the bottom surface;
- wherein the sidewall surface includes a first projection extending inward from the sidewall surface and wherein the first projection is connected to the bottom surface of the container receiver;
- and
- a plurality of wheel assemblies connected to a plurality of wheel receivers connected to the lower surface of the trolley body;
- and
- wherein the bottom surface of the container receiver supports the base of the container and the first projection engages the container to help secure the container to the trolley.
