  • Refill-preventing valve for non-refillable containers
    Patent number: 5467798
    Abstract: A non-refill valve for a non-refillable container, comprising a valve body having an inlet and an outlet and a passage through the valve body interconnecting the inlet and the outlet. A valve stem slides in the passage and has an axial passageway that extends partway therethrough and that terminates laterally in a passageway that extends through a side wall of the stem intermediate the ends of the stem. A ball in the stem rests on a seat on the stem and closes the valve stem passageway against the flow of gas from the outlet towards the inlet. A first spring urges the ball against the seat to permit flow of gas only in a direction from the inlet to the outlet by displacing the ball from the seat against the action of the first spring in an open position of the valve. A second spring urges the stem in the direction of the flow of gas from the inlet to the outlet, and a seal acts between the stem and the valve body.
