A one-piece container formed from a single unitary blank of corrugated paperboard has a bottom wall, opposed side walls and inwardly inclined opposed end walls. Stacking tabs project upwardly from the end walls and tab locks in the bottom wall receive the stacking tabs of a subjacent container when the containers are stacked on top of one another. A reinforcing corner post extends the full height of the container in each corner. The corner posts are formed by panels extending from opposite ends of the end walls, wherein the panels include a first panel foldably joined to an end of an associated end wall and adhered to an adjacent side wall, a second panel foldably joined to the first panel and extending diagonally across the corner, and a third panel foldably joined to the second panel and adhered to an adjacent side wall.

1. A one-piece container formed from a single unitary blank of corrugated paperboard, the one piece container comprising: a bottom wall, opposed side walls and opposed end walls, one of either the side walls (12, 13) or the end walls (14, 15) being inwardly inclined;stacking tabs (18) on a top edge
1. A one-piece container formed from a single unitary blank of corrugated paperboard, the one piece container comprising: a bottom wall, opposed side walls and opposed end walls, one of either the side walls (12, 13) or the end walls (14, 15) being inwardly inclined;stacking tabs (18) on a top edge of the inwardly inclined walls, the stacking tabs extending coplanar with the associated inclined wall;tab locks in the bottom wall in positions to receive the stacking tabs of a subjacent container with an associated inclined wall;reinforcing corner posts (40) each of which extending diagonally across each interior corner of the container and are formed by respective folded corner post panels (41) on opposite side edges of each end wall, each of the respective folded corner post panels (41) being divided by spaced apart parallel folds (42) and (43) into respective first, second and third panels (44), (45) and (46), the first panels positioned contiguous to the associated end wall (14 or 15), being folded perpendicular to the associated end wall and adhered to an adjacent inner end surface of the adjacent side wall (12 or 13), wherein a respective corner post pad (47) being foldably joined to a top edge of the respective first panel (44), the corner post pad being folded down to lie over top of an upper end of the respective reinforcing corner post, the second panels (45) being folded at an acute angle to the first panels (44) so that they extend diagonally across the interior corner of the container, and the third panels (46) lie against and are adhered to an inner surface of the adjacent end wall and wherein each of the third panels (46) have a stacking tab (18A) on an upper edge thereof in alignment with and lying against the stacking tab (18) on an adjacent said inwardly inclined end wall, whereby said stacking tabs have a double thickness. 2. The container of claim 1 wherein each of the reinforcing corner posts extending the full height of the container in each corner. 3. The container of claim 1 wherein the end walls (14, 15) are the inwardly inclined walls. 4. The container of claim 1 wherein two lid panels each of which is foldably joined to an upper edge of the opposed side walls (12, 13); each of the lid panels has a slot in each opposite end thereof in position to receive the stacking tab on the inclined end wall when the lid panel is folded into horizontal closed position over the container; anda locking tab is foldably joined to an end of each of the lid panel adjacent each said slot, the locking tabs adapted to fold downwardly over an upper edge of a respective said end wall, and a heel on each said locking tab adapted to extend upwardly and lie against an outer surface of an adjacent stacking tab when said locking tab is folded downwardly over a said end wall. 5. A blank for making a container having a bottom wall, opposite inclined end walls, opposite side walls, a full depth corner post in each corner, stacking tabs on upper edges of the end walls, and tab locks in the bottom wall for receiving the stacking tabs, wherein said blank comprises: a central bottom wall panel;a side wall panel foldably joined to each opposite side edge of said bottom wall panel;a end wall panel foldably joined to each opposite end edge of said bottom wall panel; andcorner post panels foldably joined to opposite ends of each said end wall panel, said corner post panels each comprising a first panel foldably joined to an end of an associated said end wall panel, a second panel foldably joined to said first panel, and a third panel foldably joined to said second panel, wherein said first panels are adapted to lie against and be adhered to an inner end surface of an adjacent said side wall panel, said second panels are adapted to extend diagonally across a corner, and said third panels are adapted to lie against and be adhered to an inner surface of an adjacent said end wall panel in a container erected from said blank wherein:said end wall panels and said side wall panels each have an upper edge opposite the edge thereof foldably joined to the bottom wall panel,said first, second and third panels each have an upper edge aligned with the upper edge of a respective associated said end wall panel,a corner post pad is foldably joined to an upper edge of each said first panel, and stacking tabs extend from the upper edges of said end wall panels and said third panels and wherein:a lid panel is foldably joined to the top edge of each said side wall panel;each said lid panel has a slot in each opposite end thereof in positions to receive a respective said stacking tab in a container erected from the blank, anda locking tab is foldably joined to an end edge of each said lid panel adjacent each said slot, said locking tabs adapted to fold downwardly over an upper edge of a respective said end wall in a container erected from said blank, and a heel on each said locking tab adapted to extend upwardly and lie against an outer surface of an adjacent stacking tab when said locking tab is folded downwardly over said end wall in a container erected from said blank.
