ABSTRACT:
A carton for fast food items is provided. The carton has a polygonal bottom panel with four generally rectangular side wall panels foldably attached to the edges thereof. A major top closure panel is foldably connected to one of the side wall panels, and a minor top closure panel is foldably connected to the opposite side wall panel. The minor top closure panel carries a closure tab having bilateral locking wings. A slot is provided in the major top closure panel for receiving the closure tab. The carton includes corner closing, backfolded, double layer webs at each corner. Each web is foldably connected to a first associated side wall panel at a perforated fold scoreline collinear with the edge of that panel, and to an adjacent side wall panel along an angled perforated or cut fold scoreline extending outwardly at approximately 45.degree. from each corner of the bottom wall panel. The present invention also encompasses a die cut blank for forming the carton.
The present invention also includes a forming fixture for erecting the carton at the point of use. The forming fixture has a base and two pairs of forming walls, each wall angling upwardly and outwardly from the base, one pair of walls being disposed at an angle of approximately 45.degree. to the base, while the other pair of walls is at approximately a 60.degree. angle.
