A unitary carton end for supporting a fixture for shipment and storage in a normal, upright orientation, said fixture having normal top and bottom sides and including a weight bearing flange which extends laterally from said carton end fixture adjacent the normal top of said fixture, comprising:
- a vertical wall having a normal top and bottom edge, and two sides, said wall formed of sheet material;
- a partial bottom floor wall formed of sheet material extending from said normal bottom edge of said vertical wall and positioned adjacent said normal bottom of said fixture;
- and
- a hollow vertically extending column formed unitarily of sheet material with said carton end wall, said vertically extending column abutting said bottom floor wall at one end and said upper weight bearing flange at the other end, said column having at least two vertical sides extending inward from said vertical wall and joined by a vertically extending fold spaced a substantial distance inward from said vertical wall, said column spaced a substantial distance inward from said side edges of said vertical wall and positioned with the vertically extending fold under the weight bearing flange to support said fixture in said normal, upright orientation by transmitting the weight of said fixture from said upper weight bearing flange to said bottom floor wall through the folded portion of said column.
A unitary carton end for supporting an upper weight bearing flange of an enclosed fixture having a top and bottom, comprising:
- a vertical wall formed of sheet material;
- a partial bottom floor wall formed of sheet material extending unitarily from said vertical wall and positioned adjacent said bottom of said fixture;
- a vertically extending column formed unitarily of sheet material with said vertical wall, said column abutting said floor wall at one end and said weight bearing flange at the other end, said column including at least one vertically extending fold;
- and
- said partial floor wall including means for holding said one vertically extending fold of said column in a folded configuration, comprising a recessed pocket on one surface of said partial floor wall conforming to the perimeter of said column and positioned around said column.
A carton blank for forming one end of a carton for enclosing a device, comprising:
- a flat end wall portion including four linear sides;
- three flaps extending unitarily from three of said four linear sides of said end wall portion;
- a fourth flap extending unitarily from the remaining linear side of said end wall portion, said fourth flap including an extension for forming a hollow column within said carton end for bearing the weight of said enclosed device, said column including at least one fold line in the direction of the weight of said device;
- and
- one of said three flaps including means for holding said hollow column folded about said fold line, comprising a recess in said one of said three flaps.
