ABSTRACT:
A molded plastic fruit container is constructed to provide ventilation without uncontrolled drippage into a lower container by virtue of bottom openings surrounded by raised rims, side openings that terminate above the bottom, and end weep holes to direct drippage away from a lower stacked container. The end walls are each provided with an end reinforcing rib grid that has gusseted horizontal ribs that extend further outwardly for improved engagement with a mechanical gripper. A bottom reinforcement rib grid is inset from a rim circumscribing the bottom so that the bottom rib grid is receivable in a lower container for secure stacking. The ribs of the bottom rib grid have ramped ends to allow an upper container to be swept off easily. The transverse ribs underneath the bottom openings are cut away to maintain ventilation and allow stacking with a conventional wooden crate.
