ABSTRACT:
A plastic container is provided having a cover pivotally connected to a bottom wall and provided with side flaps extending therefrom for interconnecting the cover and sidewalls. The side flaps each include an arc-shaped edge and a locking tab formed in the side flap spaced inwardly from the arc-shaped edge, with the locking tab of each side flap being movable out of the plane of the side flap. In addition, each of the sidewalls includes a locking slot formed therein, with each locking slot including a central slot portion and end slot portions forming end locking elements at each end of the central slot portion, with the end locking elements being movable out of the plane of the respective sidewalls. Each of the locking tabs is engageable with and movable relative to a respective locking slot, such that movement of a locking tab to engage one of the end locking elements operates to bias the engaged locking tab and locking element out of their respective planes and to automatically lock the cover of the container in an open or closed position.
A cabinet is also provided for holding a plurality of such containers in an aligned or stacked arrangement.
