ABSTRACT:
A bracket for strenghtening a carton which has a bottom wall, side walls, an end flap and interior flaps, for holding the flaps and for supporting additional cartons in a stack of cartons, comprising a flange parallel to the bottom wall and a pair of members perpendicular to the bottom wall joined by the flange and extending substantially throughout the height of the carton to resist the bending and twisting of the carton. The members are each positioned to substantially enclose one of the corners of the carton and to abut an edge, perpendicular to the bottom wall, of one of the side walls and the end flap. Tabs are provided to align a stack and to lock the carton top closed.
