ABSTRACT:
An improved pour spout assembly in a paperboard carton comprises a pour spout front panel formed from a section of a vertical side wall of the carton, and a component adhered to the interior surface of the side wall. The component has two sections separated by a frangible score. One section comprises a pour spout back panel and a pair of wings. The other section is a backboard having a pair of prongs that extend downward. Each prong forms a channel with an adjacent vertical edge of the pour spout opening to hold a wing in abutting relationship with the edge. The prongs also act as stoppers to prevent the pour spout from being pushed back into the interior of the carton.
