## Abstract

Several embodiments of plastic dumpsters with improved strength and durability are disclosed. In one embodiment, gussets connect pockets to bevel walls, connecting the side walls to front and rear walls of the dumpster. The bevel walls are stronger than the side walls of the dumpster. Other embodiments disclose gussets integral with front and rear walls of the dumpster for improved strength. Other embodiments disclose removable, separately formed sleeves that are secured to the sides of the dumpster to form pockets for receiving the forks of a truck.

## Claims

### Claim 9

A dumpster comprising:
a base wall;
a pair of opposite first walls extending upwardly from the base wall;
a pair of opposite second walls extending upwardly from the base wall; and
a pocket for receiving a fork of a lift, the pocket on one of the first walls, the pocket including a pocket wall having alternating single-wall thickness sections and box beam sections.

### Claim 10 (depends on 9)

The dumpster of claim 9 wherein the box beam sections each have an open end.

### Claim 11 (depends on 10)
