An auto lock tray is formed from a single blank of cut and scored foldable material comprising a bottom panel, side and end walls extending in an upright condition at each edge of the bottom panel and diagonally disposed product supporting panels interiorly of the tray which extend from the upper edges of the side walls downwardly at acute angles with the bottom of the tray. The product supporting panels are retained in position within the tray by a pair of locking flaps including interengaged tabs and slots which become fully engaged as a result of an over center folding action.

An auto lock tray prepared from a single blank of material comprising: (a) a substantially centrally located bottom panel of generally rectangular shape having paired side and end walls foldably attached thereto, said side and end walls having upper edges and ends with corner connecting flaps foldably attached to the ends of said side walls, and a first pair of locking flaps foldably attached to the upper edges of said end walls, said locking flaps each include two or more locking tabs on the outer edges thereof which cooperate with locking slots formed in the bottom panel along the fold lines foldably attaching the end walls to the bottom panel and the corner connecting flaps are each captured between an end wall and a locking flap to form the tray with upstanding side and end walls; (b) a pair of product supporting panels one foldably attached to the upper edge of each of said side walls and located inside the tray at an acute angle with respect to said bottom panel, said product supporting panels each including a plurality of matching product accepting slots for accepting and retaining products packaged in the tray and a panel support flap at each end of said product supporting panel for supporting the ends of the product supporting panels, each of said panel support flaps having adjacent edges which abut respectively the bottom panel and a side wall of the tray at a corner of the tray; and, (c) a second pair of locking flaps one foldably attached to the inner side of each of said product supporting panels, said second locking flaps each including alternating tabs and slots formed at their outer edges which interlock in the over center position of said locking flaps, said flaps substantially fully overlapping one another in their unlocked condition when lying in a plane defined by the top of the tray, but which become interlocked when they are urged past their over center position inside the tray to provide the sole means for retaining each product supporting panel in its acute angular position within the tray.
