Abstract
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.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
144 words
In a container for fruit or the like that is made of substantially impervious material and includes a horizontal bottom wall completely circumscribed by vertical side and end walls, the improvement wherein: at least one elongated ventilation opening is formed through the bottom wall and is completely surrounded by a raised rib which extends above the level of the bottom wall; there are a plurality of reinforcing ribs on the lower surface of the bottom wall that span the ventilation opening; at least one weep hole is formed through a vertical wall, each said weep hole extending at least partially below the level of the raised rib; and the upper surface of the bottom wall outside of the raised rib is flat to define a channel so that fluid collected thereon will flow out through the weep holes rather than through the ventilation openings.

Claim 3
Dependent Claim
31 words
A container according to claim 1, wherein there is also at least one ventilation opening through a vertical wall with its lower end above the lowest level of the weep hole.
Claim 4
Dependent Claim
64 words
A container according to claim 1, and in which the outer surface of each of the end walls is provided with an outwardly extending reinforcing rib grid comprising vertical and horizontal ribs, wherein the horizontal ribs extend further outwardly at a given height than the vertical ribs at the same height to provide transverse support ledges for enhanced engagement with a vertical gripping mechanism.
