Abstract
A generally cylindrical, tub-shaped carton having a flat bottom, and particularly suited for containing butter or margarine, is formed of a single paperboard blank, and is characterized by having a generally cylindrical-shaped side wall formed of two panels, each of which is integrally formed with and hingedly connected to one of two opposing sides of a hexagonal horizontal base portion. Intermediate each of the remaining sides of said hexagonal base portion and a side wall panel is an articulated webbed corner which, in the erected position of the carton, is wholly disposed within the tub-shaped carton in a flattened relationship against said side wall panels to reinforce the side wall seam of the tub-shaped carton. The hexagonal base or bottom of the carton is flat, thereby offering a more stable carton having greater capacity at a reduced cost of manufacture, and also offering better sealing of the carton during packaging of the butter therein.
