10,797. Dunne, R. May 23. Bottles, non-refillable.- The bottle is provided with a hollow stopper 1, preferably of glass, having a venting-passage at one side, and a lateral opening 7 to permit the outflow of liquid, which escapes through an opening 8 in the top of the stopper. The stopper rests upon a flange 15 formed at the lower end of the neck, which flange also forms a seat for a spring-controlled valve 9. A cork ring 14 is inserted to ensure a close fit of the stopper in the bottle. When a spiral spring is used to control the valve, a guide-rod is provided as shown. The lower end of the stopper is of frusto-conical shape, to limit the movement of the valve.
