ABSTRACT:
A stackable tray is constructed of a bottom wall, a pair of end walls extending upwardly from the bottom wall, and a pair of side walls extending upwardly from the bottom wall and between the end walls. The end and side walls are preferably divergent in an upward direction. A pair of stacking support walls extend upwardly relative to the bottom wall, and are spaced slightly inwardly from the tray end walls. The stacking support walls are interconnected with the tray side walls. The side walls and stacking support walls are constructed of folded panels, and tabs are formed on the stacking support walls and on inner panels of the side walls, and the tabs of the stacking support walls and side walls function to interconnect the stacking support walls with the side walls upon folding of the stacking support wall panels and the side wall panels.
