Abstract
A flat of fiberboard in knocked-down form for setting up into a tray which has strengthened corners. The flat consists of laminated strength-producing connecting corner tabs between hinged side-wall forming flaps. The tabs are formed on the ends of the flaps and some of the flaps are provided with angular fold lines which provide foldable sections in these flaps, the fold lines extending from the flap hinge lines of the respective flaps to a point within the flaps and a slit being provided from that point in each flap to the outer edge of the flap to permit folding of the foldable flap sections.
