Abstract

A waste container includes a body portion including an outer wall extending upward from a base wall. A lid is pivotably secured to the body portion. A latch assembly selectively secures the lid to the body portion. The latch assembly includes a handle rotatably mounted to the lid and connected to a lower actuator portion. The lower actuator portion has a disk portion with at least one cam portion. The disk portion is rotatable upon rotation of the handle by a user. Rotation of the cam portion selectively releases the latch assembly securing the lid to the body portion.

First claim

What is claimed is:

1. A waste container comprising:
a body portion including an outer wall extending upward from a base wall;
a lid; and
a latch assembly selectively securing the lid to the body portion, the latch assembly including a handle rotatably mounted to the lid and connected to a lower actuator portion having a disk portion, the disk portion having a lower surface having at least one cam portion projecting downward, such that the disk portion is rotatable upon rotation of the handle by a user and such that rotation of the at least one cam portion selectively releases the latch assembly securing the lid to the body portion.

2. A waste container comprising:
a body portion including an outer wall extending upward from a base wall;
a lid; and
a latch assembly selectively securing the lid to the body portion, the latch assembly including a handle rotatably mounted to the lid and connected to a lower actuator portion having a disk portion having at least one cam portion, such that the disk portion is rotatable upon rotation of the handle by a user and such that rotation of the cam portion selectively releases the latch assembly securing the lid to the body portion, wherein the latch assembly further includes an upper latch portion and a lower latch portion, the upper latch portion including an actuating lever, the cam portion of the disk portion is configured to actuate the actuating lever and release the upper latch portion from the lower latch portion.

3. The waste container of claim 2 wherein the cam portion is configured to displace the actuating lever vertically upon rotation of the disk portion.

4. The waste container of claim 3 wherein the disk portion includes a plurality of cam portions, each of the plurality of cam portions configured to actuate the actuating lever upon rotation of the disk portion.

5. The waste container of claim 1 wherein the lid is hingeably connected to a handle portion spaced rearwardly of an upper edge of the body portion.

6. The waste container of claim 5 further including a plurality of wheels rotatably connected to the body portion.

7. A waste container comprising:
a body portion including an outer wall extending upward from a base wall;
a lid; and
a latch assembly selectively latching and unlatching the lid to the body portion, the latch assembly including a handle rotatably mounted to the lid and configured to selectively latch and unlatch the latch assembly upon rotation of the handle, an upper surface of the lid and a lower surface of the handle including interfering portions that are positioned to interact with one another to resist rotation of the handle out of an unlatched position.

8. The waste container of claim 7 wherein the interfering portions include a plurality of convex surfaces on the upper surface of the lid and the lower surface of the handle.

9. The waste container of claim 7 wherein the interfering portions include a plurality of bosses on the upper surface of the lid and the lower surface of the handle.

10. A waste container comprising:
a body portion including an outer wall extending upward from a base wall;
a lid pivotably secured to the body portion, the lid including an upper panel portion and a lip projecting downward from a periphery of the upper panel portion, a plurality of reinforcement ribs extending downward from the upper panel portion, the reinforcement ribs extending forwardly from the lip at a rearward edge of the lid and spaced away from side edges of the lid.

11. The waste container of claim 10 wherein the reinforcement ribs extend from a rearward edge of the lid and then curve toward one another proximate a front of the lid.

12. The waste container of claim 1 wherein the lower surface of the disk portion includes a recessed portion adjacent the cam portion, the cam portion including a ramp portion adjacent the recessed portion.

13. The waste container of claim 1 wherein at least one cam portion vertically displaces a first component of the latch assembly upon rotation of the disk portion to selectively release the latch assembly.

14. The waste container of claim 1 wherein the outer wall of the body portion includes a front portion opposite a rear portion, the lid hingeably mounted proximate the rear portion of the outer wall, the latch assembly selectively securing the lid only to the front portion of the outer wall of the body portion.

15. The waste container of claim 1 wherein the outer wall of the body portion includes a front portion opposite a rear portion, the lid hingeably mounted proximate the rear portion of the outer wall, the handle rotatably mounted to the lid closer to the front portion than to the rear portion of the outer wall.

16. The waste container of claim 15 wherein the lid is hingeably connected to a handle portion spaced rearwardly of an upper edge of the body portion.

17. The waste container of claim 16 further including a plurality of wheels rotatably connected to the body portion.

18. The waste container of claim 17 wherein the lower surface of the disk portion includes a recessed portion adjacent the cam portion, the cam portion including a ramp portion adjacent the recessed portion.

19. The waste container of claim 10 wherein the reinforcement ribs are spaced about ¼ of a width of the lid from the side edges of the lid.

20. The waste container of claim 17 wherein the lid is hingeably connected to a handle portion spaced rearwardly of an upper edge of the body portion.

21. The waste container of claim 7 wherein the interfering portions include a plurality of convex surfaces on at least one of the upper surface of the lid and the lower surface of the handle.

22. The waste container of claim 7 wherein the interfering portions include a plurality of bosses on at least one of the upper surface of the lid and the lower surface of the handle.
