8381. Guinane, M. April 1. Stoppers; refilling, preventing.-Relates to bottles which cannot be refilled after having been once emptied. The neck 3 is tapered to form a seat for the ball valve 8 and has a solid portion 4 formed with a hollow underside 5 and a liquid passage 6. During filling, the valve is held up by the wire 9 as shown, and after the bottle is filled the wire is withdrawn, allowing the valve to drop to its seat. When the bottle is inverted, the valve drops into the hollow 5 and permits the contents to be poured out. When the bottle is returned to the upright position, the valve drops to its seat and prevents the reintroduction of liquid. The mouth of the bottle is normally closed by an ordinary cork.
