ABSTRACT:
A flow controlling pouring spout has a hollow body portion provided with structure to facilitate attachment to the lip about a pouring opening of a container. A spout portion extending normally generally horizontally communicates with the interior of the container through the hollow body portion and has a baffle separating a lower pouring passage and an upper displacement air passage which extends from adjacent to the discharge opening of the spout to the inner end of the spout and has a displacement air opening from the inner end of the air passage to the inner end of the pouring passage. A hinged closure plug is mounted on the discharge end of the pouring spout. Swivel structure connects the pouring spout with the base portion to permit turning the spout from pouring orientation to non-pouring orientation. Stabilizing and flow controlling slidably cooperating flanges are provided on the swivelly related base portion and spout.
