Abstract
This cover for an opened beverage container has a pivoted valve in the withdrawal passage that is opened and closed according to the position of a tubular spout integral with the valve. The valve is supported by journals engaging bearings, and having a conical sealing portion. The spout has a ball-ended vent plug engageable with a vent opening in the cover, with the opening having a snap-in section and a dissociated more relaxed sealing section that continues to grip the ball end gently after repeated uses of the snap-in function.
