A fully erected one-piece, four wall container made of a foldable material having a tray with a bottom wall panel, a front wall, a rear wall and two side walls. Each of the front wall, the two side walls and the rear wall are configured to be folded to a position that is perpendicular to the bottom wall panel. Locations on the front wall and the rear wall that are mutually adjacent the first and second side walls each have a triangular piece hingedly joined thereto and to a respective one of the first and second side walls. Each triangular piece is configured to be oriented perpendicular to respective first and second side walls and parallel to respective front and rear walls, all in response to each of the front, rear and first and second side walls becoming oriented perpendicular to the bottom wall panel. |

1. A fully erected one-piece, four wall container made of a foldable material, comprising:
a tray having a bottom wall panel, said bottom wall panel having a front edge, a pair of side edges and a rear edge, a planar front wall hingedly joined to said front edge at a front bottom edge, a planar first side wall hingedly joined to one of said side edges at a first side bottom edge, a planar second side wall hingedly joined to the other of said side edges at a second side bottom edge, a planar rear wall hingedly joined to said rear edge at a rear bottom edge, each of said front wall, said first and second side walls and said rear wall being configured to be folded to a position that is perpendicular to said bottom wall panel, locations on said front wall and said rear wall that are mutually adjacent said first and second side walls each having a planar triangular piece having only three substantially straight edges hingedly joined thereto and hingedly joined to a respective one of said first and second side walls, each said triangular piece being configured to be oriented perpendicular to respective said first and second side walls and parallel to respective said front and rear walls, all in response to each of said front, rear and first and second side walls becoming oriented perpendicular to said bottom wall panel; a first flap hingedly joined to said front wall along an edge that is remote from said front bottom edge that is hingedly joined to said front edge; a slit extending coextensively along the hinge joining said first flap to said front wall, at least said front wall having a cut-out that opens into said slit; a lid panel hingedly joined to said rear wall along a rear top edge that is remote from said rear bottom edge that is hingedly joined to said rear edge and configured to overlay said tray and said bottom wall panel; and a second flap hingedly joined to said lid panel along an edge that is remote from said rear top edge that is hingedly joined to said rear wall, said second flap being configured to be oriented perpendicular to said lid panel and extending through said slit when said lid panel becomes oriented parallel to said bottom wall panel and overlays said tray and an upwardly facing surface of said first flap; wherein the front wall, the first side wall, the second side wall and the rear wall define sides of a rectangular boundary coextensive with a periphery of the bottom wall panel and the triangular pieces extend outside of the rectangular boundary; and wherein said front wall and said rear wall each have a first width dimension, said bottom wall panel has a second width dimension, and said first flap and said lid panel have a third width dimension, with said first and third width dimensions being the same.
