ABSTRACT:
A pour spout for conducting fluid from a container to a receptacle. The pour spout includes a conduit member having a first end interconnectable with the container and a second end having a discharge opening and a vent opening, and a closure member positioned adjacent to the discharge opening. The closure member is movable relative to the conduit member between a first position where the discharge and vent openings are closed, a second position where the vent opening is open, and a third position where the discharge opening is open. A closure locking device prevents bypassing the second position during movement of the closure member from the first position to the third position. A vent locking device prevents movement of the closure member from the first position to the second position when the container is tipped beyond a predetermined angle. Another device retains sub-ambient pressure within the container when closure member is in the second position.
