Abstract
A two-piece paperboard container composed of an outer carton and liner includes a paperboard pour spout formed from portions of the outer carton and liner. The pour spout includes a spout body and a pair of spout wings hingedly connected to opposing edges of the spout body. The outer carton encompasses the liner and includes a spout body reinforcing panel overlying the spout body. The spout body reinforcing panel is adhered to the spout body and moves in tandem with the spout body in response to the pour spout being opened and closed. The outer carton further includes a plurality of top and bottom flaps adapted to form the respective top and bottom of the container. A pair of backboard panels extending from one of the top flaps are folded to form a backboard of the pour spout.
