ABSTRACT:
A unitary paperboard blank for forming a tray with point-of-use flip-up partitions. The blank has an extension flap attached to the top edge of one of the side walls along a breakaway line of weakness. The extension flap has one or more divider panels formed therein depending upon the number of compartments desired in the tray. The side wall with its attached extension flap is folded over the bottom panel and the extension flap is glued to the inside surface of the bottom panel. The side wall is then broken away from the extension flap and the tray then formed on conventional tray forming equipment.
