Produce tray

A tray comprising a bottom panel, side walls foldably connected to opposite sides of said panel via a pair of substantially parallel side fold lines, a pair of end wall forming panels, each of said end wall forming panels being defined in said bottom panel and said side walls by a line of weakness extending across said bottom panel and partway into each of said side walls, and a first pair of fold lines extending one from each end of said line of weakness toward a junction formed with the projection of the adjacent of said side fold lines, a second pair of fold lines extending one from said line of weakness toward each of said junctions to form in each of said end wall forming panels, an end wall and a pair of side connecting walls, said first and second pairs of fold lines being symmetrically arranged with respect to the longitudinal centre line of the tray, each of said side connecting walls being in overlying face-to-face relationship with its adjacent of said side walls, a reinforcing side panel foldably connected to each of said side walls and positioned in face-to-face overlying relationship to the side wall to which it is connected and its adjacent said side connecting wall, end edges at each end of said reinforcing side wall panels, said end edges abutting said end walls thereby to hold said end walls in erected position, one of said reinforcing side wall panels having a flap foldably connected to its free edge and the other of said reinforcing side wall panels having a bottom wall foldably connected to its free end, said foldable connection between said side walls and said reinforcing side wall panels and between said one reinforcing side wall panel and said flap and said other reinforcing side wall panel and said bottom wall being substantially parallel to said pair of fold lines connecting said side walls with said bottom panel, releasable means to lock said bottom wall in face-to-face relationship with said bottom panel and said reinforcing side wall panels in position relative to said side walls, said side connecting walls and said end walls thereby to form the sole means for holding said tray in erected position.
