Abstract
Abstract The present invention provides a multi-piece container which locks together. A hinged locking section is attached to each end of a base. Side wall locking members have locking flaps which interact with the hinged locking sections and upper locking flanges which interact with internal locking flaps on the side walls of a side wall section to lock the side walls to the base.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
187 words
A container comprising a base member, end locking sections hingedly attached to the end edges of said base member, a pair of side wall locking members each locked to one of said end locking sections, each of said side wall locking members having a first central lower locking flap on the top face of one of said end locking sections, and side locking flaps extending between said end locking sections and said base member, a central side wall extending upwardly from said central locking flap along said hinged attachment between said locking section and said base member, side wall elements extending upward from said side locking flaps, a side wall locking flange on the upper edge of said central side wall and said side wall elements, a rectangular side wall member telescoped around the outer edge of said side wall locking members, said side wall member having side walls, side wall locking flaps extending from the lower edge of each side wall, said side wall locking flaps being hingedly attached to said side walls and extending upwardly internally of said side walls and mating with said flange.
Claim 2
Dependent Claim
187 words
A container comprising a base member, end locking sections hingedly attached to the end edges of said base member, a pair of side wall locking members each locked to one of said end locking sections, each of said side wall locking members having a first central lower locking flap on the top face of one of said end locking sections, and side locking flaps extending between said end locking sections and said base member, a central side wall extending upwardly from said central locking flap along said hinged attachment between said locking section and said base member, side wall elements extending upward from said side locking flaps, a side wall locking flange on the upper edge of said central side wall and said side wall elements, a rectangular side wall member telescoped around the outer edge of said side wall locking members, said side wall member having side walls, side wall locking flaps extending from the lower edge of each side wall, said side wall locking flaps being hingedly attached to said side walls and extending upwardly internally of said side walls and mating with said flange.
Claim 3
Dependent Claim
40 words
The container of claim 1 in which said flange is formed of side wall locking elements hingedly attached to the upper edge of said side walls, said side locking elements extending downwardly from the upper edge of said side walls.
Claim 4
Dependent Claim
14 words
The container of claims 1 or 2 further comprising legs on said base member.
Claim 5
Dependent Claim
14 words
The container of claims 1 or 2 further comprising a cover on said container.
Claim 6
Independent Claim
