ABSTRACT:
A nestable and stackable container is provided with the bottom, end walls and side walls fixedly secured to each other to form a unitary structure. The container further comprises a plurality of alternately inwardly and outwardly offset portions on the side walls extending upwardly from the bottom, the inwardly offset portions each having a generally horizontal shoulder defining its upper edge. A stacking shelf is mounted on each side wall for pivotal movement about a horizontal axis extending longitudinally of the side wall at a location below and outwardly of the wall from the shoulder. The stacking shelf is pivotal about the axis, between a stacking position wherein the shelf overlies and projects inwardly of the shoulder, and a nesting position wherein the shelf is inclined upwardly and outwardly of the shoulder. A stacking rail is formed at the bottom of each opposed side wall, with the rail being receivable in a recess formed in the stacking shelf when the shelf is in its stacking position. A generally flat interference surface on the shelf is spaced from and oriented relative to the pivotal axis such that the interference surface yieldably slides across the shoulder of the inwardly offset portion to frictionally resist pivotal movement of the shelf through at least an intermediate portion of its movement between the nesting and stacking positiions. The container further comprises a plurality of bail structures formed in and horizontally spaced along the shelf.
