ABSTRACT:
A single paperboard blank for forming a carton having a tear open spout for dispensing material contained therein. The blank includes a first main panel with first and second side panels and end flaps hingedly connected thereto by way of fold lines. In addition, a second main panel is hingedly connected to the second side panel and includes a third side panel and end flaps hingedly connected thereto by way of fold lines. A closure flap is formed in the third side panel and a spout panel is hingedly connected to the third side panel. The formed carton has a plurality of side walls hingedly connected to one another by fold lines, a top wall and a bottom wall, with one of the side walls including an outer panel and an inner panel adhesively secured thereto with closure flap formed in the inner panel. A tear protective flap is formed in the outer panel for sealing the carton until the initial use. The spout is hingedly connected with the inner panel and adhered to the closure flap, such that, the spout and the closure flap extend outward from the carton when opened to form the passage through which the material in the carton may be poured. Retention wings are included on the spout to keep it from opening too far and to constrict the flow of material from the carton.
