ABSTRACT:
A valve is provided which includes a dispensing spout and a spout insert. The spout insert includes a pair of upwardly extending posts which project up and into the spout. The spout urges the posts towards each other and a valve bridge extends between the posts and overlays a hole defined in the spout insert through which liquid flows when a suction force is applied to the spout. When no suction force is applied to the spout, the valve bridge closes the hole.
