ABSTRACT:
A generally cylindrical, tub-shaped carton having a reinforced 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 hingedly connected to a horizontal base portion. The latter includes a rectangularly-shaped central portion to which is integrally connected on opposite sides thereof two triangularly-shaped base portions. Intermediate each triangularly-shaped base portion and a side wall panel is an articulated webbed corner which, in the erected position of the carton, is of multiple paperboard sheet construction, and which functions to reinforce the base 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 reduced cost of manufacture, and also offering better sealing of the carton during packaging of the butter therein.
