ABSTRACT:
A container is provided with a pour spout fitment. The fitment carries a flange which secures the fitment to the container, the flange surrounding a dispensing opening in the container. The pour spout is normally externally closed by a screw cap threaded thereon. A frangible membrane normally spans and internally closes the dispensing opening. A hollow piercing insert is positioned within the pour spout lumen, the lower edge of the insert being serrated to define cutting teeth. The screw cap is removed and the piercing element pushed downwardly to thereby rupture the frangible membrane and permit dispensing from the container. The interior of the spout is provided with a plurality of axially spaced, inwardly extending ribs which cooperate with outwardly extending protrusions on the piercing insert to thus define a plurality of discrete axial locations of the piercing insert relative to the spout.
