A pour spout assembly for a container. A first tongue and a second tongue are formed in a wall of the container. The first tongue is defined by a transverse slit in the wall and downwardly extending slits in the wall at opposite ends of the transverse slit. The second tongue is defined by the transverse slit and by upwardly extending slits at opposite ends of the transverse slit. A central portion of a web member is attached to an inner face of the first tongue. The web member includes outer glue panels attached to the container wall and connected to the central portion by accordian pleat panels. The second tongue swings in response to contact with the central portion of the web as the central portion of the web passes it in moving between positions inside and outside the container as the first tongue swings between a closed position in which the first tongue is aligned with the wall and an upper section of the central portion of the web covers and closes the transverse slit and an open position in which the first tongue extends upwardly and outwardly from hinging means of the first tongue.
