ABSTRACT:
A collapsible plastic container includes a top perimeter, a bottom and a plurality of sidewalls formed in a generally rectangular configuration. At least one of the sidewalls is pivotable between a collapsed position and an opened position. An engaging portion of the pivotable sidewall includes a first opening therein, which is disposed adjacent a receiving portion of either the top perimeter and the bottom including a second opening therein in the opened position. The first and second openings are relatively positioned such that they are aligned when the pivotable sidewall is in its opened position. A locking lug is positioned such that it is extendible into the aligned openings of an adjacent container when the container and the adjacent container are in a stacked arrangement. A lid may also be provided including a second locking lug. The structure ensures that the sidewalls are securely held in their vertical position to thereby ensure that the container will bear its maximum load. Additionally, the locking lugs prevent the sides from being pushed in when the containers are stacked or closed to thereby provide added security.
