ABSTRACT:
A one-piece blank forms a liquid-tight carton having plural rectangular side walls sealed or integral with one another at adjoining side edges and flat end panels of polygonal shape, the carton facilitating ultrasonic scaling of the end walls to the side walls through a unique set of sealing tabs on the side and end walls. The process and equipment for sealing the end walls to the side walls permits ultrasonic heating and sealing after the carton is full of liquid through a compression of the sealing tabs of these walls between facing dies which are diagonally aligned in relationship to the side and end walls. The carton formed by this blank facilitates nesting of multiple cartons, one above the other.
