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.

The conveyor system of claim 10, wherein: the lifting mechanism includes an actuating ram having a ram axis oriented parallel to the width of the main conveyor. 12. The conveyor system of claim 10, wherein: the transfer drive belt defines a serpentine belt path having first and second uppermost belt path portions located on opposite sides of the main conveyor drive belt. 13. The conveyor system of claim 12, wherein: the serpentine belt path includes a drop down belt path portion between the first and second uppermost belt path portions, the drop down belt path portion running under the main conveyor drive belt. 14. The conveyor system of claim 12, further comprising: a second transfer drive belt defining a second serpentine belt path having first and second uppermost belt path portions parallel to those of the first transfer drive belt; and a transfer frame upon which both of the transfer drive belts are mounted, the lifting mechanism being connected between the main conveyor and the transfer frame. 15. The conveyor system of claim 14, wherein: the rollers of the main conveyor are spaced at regular intervals along the length of the main conveyors; and the first and second transfer drive belts are each located between two adjacent ones of the regularly spaced rollers of the main conveyor, so that none of the regularly spaced rollers of the main conveyor need be removed to accommodate the transfer apparatus. 16. The conveyor system of claim 14, further comprising: the first and second transfer drive belts each being toothed belts; a transfer drive motor including a motor brake; and a transfer drive train between the drive motor and the first and second transfer drive belts, the transfer drive train including first and second toothed drive sprockets engaging the first and second toothed transfer drive belts. 17. The conveyor system of claim 14, further comprising: a stop abutment attached to the transfer frame and located upstream of the transfer drive belts, the stop abutment extending above the rollers of the main conveyor when the lifting mechanism of the transfer apparatus is in its raised position. 18. A method of transferring an article laterally off of a belt driven live roller main conveyor having a central main conveyor drive belt extending parallel to a length of the main conveyor, comprising: (a) engaging the article from below in at least two locations on opposite sides of the main conveyor drive belt; (b) raising the article above the rollers of the main conveyor; and (c) transporting the raised article laterally off of the main conveyor. 19. The method of claim 18, wherein: step (a) includes engaging the article in at least four locations, two of which are on either side of the main conveyor drive belt. 20. A transfer apparatus for transferring articles laterally off of a main roller conveyor, comprising: a support frame adapted to be attached to the main conveyor; a transfer frame movable relative to the support frame; a lifting mechanism, connected between the support frame and the transfer frame for lifting the transfer frame relative to the support frame; first and second toothed transfer drive belts mounted on the transfer frame; a transfer drive motor mounted on the transfer frame; and a transfer drive train connecting the drive motor to the first and second toothed transfer belts, the transfer drive train including first and second toot hed driving sprockets engaging the first and second toothed transfer drive belts, respectively. 21. The apparatus of claim 20, wherein the transfer drive motor includes a motor brake. 22. The apparatus of claim 20, in combination with the conveyor, the conveyor being a belt driven live roller conveyor. 23. The apparatus of claim 20, in combination with the conveyor, the conveyor being a line shaft drive conveyor. 24. A transfer apparatus for transferring articles laterally off of a main roller conveyor, comprising: a support frame; a transfer frame; a lifting mechanism connected between the support frame and the transfer frame; first and second transfer drive belts mounted on the transfer frame; and a stop abutment attached to the transfer frame and extending upwardly on an upstream side of the transfer apparatus, so that when the lifting mechanism is in a raised position the stop abutment extends above the main roller conveyor. 25. The apparatus of claim 24 in combination with the conveyor, the conveyor being a belt driven live roller conveyor. 26. The apparatus of claim 24, in combination with the conveyor, the conveyor being a line shaft drive conveyor. 27. A transfer apparatus for transferring articles laterally off of a main roller conveyor, comprising: a support frame having a width and a length; a transfer frame; first and second transfer drive belts mounted on the transfer frame and extending parallel to the width of the support frame; and a lifting mechanism, connected between the support frame and the transfer frame, the lifting mechanism including an actuating ram extending perpendicular to the length of the support frame. 28. The transfer apparatus of claim 27, in combination with the main conveyor, the main conveyor being a belt driven live roller conveyor. 29. The transfer apparatus of claim 27, in combination with the main conveyor, the main conveyor being a line shaft drive conveyor.
