ABSTRACT:
A disposable, self-stabilizing tray, which is shipped in a flat condition and which forms a stable, non-collapsible structure as it is being erected, is disclosed. The tray includes a transverse downwardly directed panel partition which extends between the top and bottom panel members, and which, as the tray is being erected, cams a longitudinal panel into a downwardly directed direction. A protrusion or projection from the longitudinal panel is thus cammed into a locking notch which is formed by a recessed shoulder of an opening in the bottom member of the tray. An integral blank useful for constructing the tray is also disclosed.
