The present invention includes a blank and container formed of cellulose-based materials configured to form a reusable and collapsible container. The container in the partially assembled, knock-down position lies substantially flat and is capable of being stacked and shipped. Arrival at a job site or at a time requiring the use of the container, the partially assembled knock-down container may be easily converted into a fully erect container ready for use as intended. Once loaded with product, the first and second top panels may be folded down to enclose the container. The container positions the relief scores primarily in the side panels with only a single relief score in the bottom panel. This configuration allows the bottom panel to distend while the container is in the collapsed state while not adversely affecting overall container strength.

What is claimed is: 1. A single sheet of foldable material cut and scored to define a container, comprising: a bottom panel having a substantially centrally located score line; a first side panel connected with the bottom panel along a first fold line; a pair of opposed second side panels, connected with the bottom panel along a second fold line and a third fold line, the second fold line and the third fold line being substantially parallel to one another and separated by the bottom panel; a plurality of relief score lines formed in the each of the pair of opposed second side panels, the plurality of relief score lines radiating from a respective corner of the pair of opposed second side panels and running to substantially the center of the respective pair of opposed second side panels, wherein each of the plurality of relief score lines are at a different angle relative to the second fold line; a cut-out formed in each of the opposed second side panels, each of the cut-outs being in contact with the relief score lines and being spaced from the periphery of the respective second end panel; each of the second side panels having a pair of opposed side edges, each of the second side panel side edges having a first corner panel attached thereto, the attachment forming a first side edge of each first corner panel, each of the first corner panels having a second side edge opposite its first side edge, a second corner panel attached to each of the first corner panels along the second side edge, the entire bottom edge of each of the first and second corner panels being defined by a cut line and being adjacent the bottom panel in the formed container; and wherein each pair of first and second corner panels being juxtaposed. 2. The container of claim 1, wherein the single sheet of foldable material is formed from a cellulose-based material. 3. The container of claim 1, wherein the cellulose based material is formed from at least one of a wood pulp, straw, cotton, and bagasse. 4. The container of claim 1, wherein the cellulose based material is in the form of at least one of a fiberboard, containerboard, corrugated containerboard and paperboard. 5. A blank for a container comprising: a single sheet of foldable material cut and scored to define a bottom panel; a pair of opposed first side panels connected with the bottom panel along a pair of first fold lines, the pair of first fold lines being substantially parallel and separated by the bottom panel; a pair of opposed second side panels, connected with the bottom panel along a second fold line and a third fold line, the second fold line and the third fold line being substantially parallel to one another and separated by the bottom panel; a substantially centrally located score line extending through the bottom panel and opposed second side panels; a plurality of relief score lines formed in the each of the pair of opposed second side panels, the plurality of relief score lines radiating from a respective corner of the pair of opposed second side panels and running to substantially the center of the respective pair of opposed second side panels, wherein each of the plurality of relief score lines are at a different angle relative to the second fold line; a cut-out formed in each of the opposed second side panels, each of the cut-outs being in contact with the relief score lines and being spaced from the periphery of the respective second end panel; each of the second side panels having a pair of opposed side edges, each of the second side panel side edges having a first corner panel attached thereto, the attachment forming a first side edge of each first corner panel; each of the first corner panels having a second side edge opposite its side edge, a second corner panel attached to each of the first corner panels along the second side edge; and the bottom edge of each of the first and second corner panels being defined by a cut line between the corner panels and the first side panels.
