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.

A foldable carton formed from a flat blank for use with a pair of stregthening brackets, each bracket having a stiffening flange, a pair of side members extending perpendicularly to said stiffening flange along the height of said stiffening flange, an end flange formed on each of said pair of side members extending parallel to said stiffening flange, a flap retainer depending perpendicularly from said stiffening flange, an internal member depending from said stiffening flange and extending along the height of said side members, and said end flanges and slap retainer being spaced on opposite sides of said internal member, said carton comprising: a bottom wall; a pair of side walls; a pair of end flaps; and a pair of interior flaps integrally connected to said pair of side walls; said end flaps and said interior flaps being sized and configured to be foldingly disposed in a substantially parallel orientation on opposite sides of said internal member of said strengthening bracket and be frictionally engaged by said end flanges and said flap retainer, respectively, to hold said end flaps and said interior flaps against said internal member of said strengthening bracket.
