ABSTRACT:
A pouring nozzle for a soft drink, milk or liquor bottle, carton, or the like, which has a feature in that when the container is in an upright position, the nozzle automatically closes to seal off the container. The nozzle includes an internal ball which floats on liquid trapped in the nozzle to close and seal the nozzle when the container is upright. However, the ball is forced into a cavity in the nozzle when the container is tilted over to permit liquid to flow freely from the container through the nozzle.
