A stackable container for carrying produce. The container has tapered side walls or end walls to aid in the stacking of like containers. Also, the container has locking flaps that allow the container to be erected manually and without the need for fasteners. Further, at least one tapered wall of the container has a reinforcement flap that creates a partial top structure in the upper part of the container that helps prevent bulging of the walls. The reinforcement flap also creates doubled stacking tabs and diagonal corner posts that aid in the stacking of like containers.

The invention claimed is: 1. A container formed from a blank, the container comprising: a base panel; two opposing end walls connected to the base panel at substantially a 90° angle; two opposing side walls connected to the base panel at an angle less than 90°, the side walls having a width equal or greater than the width of upper edges of the end walls and at least one stacking tab projects from an upper edge of at least one of the opposing side walls and the base panel further comprises at least one stacking slot cut into the base panel, the at least stacking one slot positioned to accept the at least one stacking tab extending from an angled side wall of a sub-adjacent container; side flaps connected to opposing sides of the side walls, each of the side flaps comprising an inner flap connected to an outer flap, wherein the inner flap has a first lock recess along a top edge thereof, the outer flap has a second lock recess along a top edge thereof and further, wherein each respective side flap is folded inwardly so that the outer flap lies flush against an inner surface of the inner flap; and locking flaps connected to the end walls by at least one pair of lock hinge assemblies, wherein each locking flap folds inwardly to sandwich the adjacent folded side flaps between the locking flap and the adjacent end wall and further, wherein each locking hinge assembly locks into the first and second lock recess of the adjacent folded side flap and wherein the at least one side wall has a first thickness and further comprises a crushed area, the crushed area having a second thickness, the second thickness being less than the first thickness, wherein a bottom of the crushed area is adjacent to the at least one stacking slot. 2. The container according to claim 1, further comprising a flap tab disposed on the base panel adjacent to the at least one stacking slot, the flap tab having a contact edge disposed adjacent and parallel to the at least one stacking slot. 3. The container according to claim 1, further comprising a reinforcement flap connected to an upper edge of a first of the at least one side walls by at least one doubled stacking tab, wherein the reinforcement flap lies flush against an inner surface of the at least one side wall. 4. The container according to claim 3, wherein the base panel further comprises at least one stacking slot cut into the base panel, the at least one stacking slot positioned to accept the at least one doubled stacking tab extending from an angled side wall of a sub-adjacently stacked container. 5. The container according to claim 4, wherein the at least one stacking slot is positioned adjacent to the at least one side wall. 6. The container according to claim 5, further comprising a flap tab disposed on the base panel adjacent to the at least one stacking slot, the flap tab having a contact edge disposed adjacent and parallel to the at least one stacking slot. 7. The container according to claim 1, wherein the at least one side wall further comprises a window recess disposed along an upper edge. 8. The container according to claim 7, further comprising at least one reinforcement piece, the at least one reinforcement piece connected to the upper edge of a second at least one side wall, wherein the reinforcement piece lies flush against an inner surface of the second at least one side wall, the at least one reinforcement piece further comprising a second corner flap connected to a side end of the at least one reinforcement piece, wherein the second corner flap extends diagonally from the at least one reinforcement piece towards one of the adjacent locking flaps. 9. The container according to claim 8, wherein each of the locking flaps comprises a second lock slot disposed along the outer edge thereof, a second lock tab projects from a side edge of the second corner flap and further, wherein the second lock tab extends into the second lock slot. 10. The container according to claim 1, wherein a first bottom tab projects from a bottom edge of each of the at least one inner flaps, a second bottom tab projects from a bottom edge of the outer flap adjacent to the at least one inner flap, at least one tab slot is disposed on the base panel adjacent to at least on of the end walls and further, wherein the first and second bottom tabs extend into the tab slot.
