Patent ID: 7328833

Claim:
A heavy duty, knockdown container that is transformable between a flat, compact orientation for storage and shipping and a deployed configuration for containing goods, the container formed from a pair of substantially identical complementary blanks that are coupled to one another, wherein each blank comprises: a generally rectangular gluing side panel having a top, a pair of sides and a bottom; an integral, generally rectangular central side panel adjacent said gluing side panel, the central side panel having a top, a pair of sides and a bottom; a folding line defined between said central side panel and said gluing side panel; an integral receiving side panel adjacent said central side panel, the receiving side panel having a top, a pair of sides and a bottom; a second folding line defined between said central side panel and said receiving side panel; a generally rectangular gluing flap foldably defined adjacent said gluing side panel for attaching the gluing side panel on a first blank to the receiving side panel on a complementary blank; a generally trapezoidal segment foldably coupled to said central side panel at the bottom thereof for mating with a similar trapezoidal segment of the complementary blank to form a foldable polygonal bottom of said container, the trapezoidal segment comprising a bottom glue flap, a spaced apart relief slot, and a glue reception region proximate the relief slot that foldably mates with the bottom glue flap on the trapezoidal segment of a complementary blank; a first, generally trapezoidal flange foldably disposed at the bottom of said gluing side panel which contiguously borders and is separated from said trapezoidal segment, the first trapezoidal flange comprising an integral, adjacent, foldable flange glue flap; and, a second, generally trapezoidal flange foldably disposed at the bottom of said receiving side panel which contiguously borders and is separated from said trapezoidal segment for coupling to the foldable flange glue flap of a first trapezoidal flange associated with a gluing side panel of a complementary blank thereby forming a foldable shelf disposed beneath the container bottom for reinforcing the container bottom when the container is deployed.
