ABSTRACT:
A carton closure is formed with cutaway areas at side edges of the minor flaps and the inner major flap, arranged so that when in the closed position portions of the minor flaps underlie the inner major flap and portions of the inner major flap underlie the minor flaps to prevent racking of the carton during filling and sealing and to provide back-up resistance during sealing operations.
