发明名称 Stackable container with tapered stacking tabs
摘要 A container has a bottom panel, side walls, and end walls, with the bottom panel having recesses for accepting stacking tabs The side walls are provided with stacking tabs which are tapered inwardly so as to align with the recesses in the bottom panel of a second container. The inwardly tapered tabs allow for easy stacking without the tabs being deformed when containers are stacked atop one another. To improve strength, the side and end walls are disposed approximately at right angles to the bottom panel. Multiple plies of material are used along the container walls to increase container strength.
