  • Pressure sensitive cap closure and valve
    Patent number: 5850908
    Abstract: A closure cap valve apparatus for mounting on the top of a beverage container. A piston valve within the cap is biased towards closure to prevent spillage. Additionally, pressure increase within the container is directed to increase sealing force of seals positioned on the piston and thus prevents the release of pressure from the container, allowing the closure to be used for carbonated beverages. The piston is displaced from the closed position, even when the container internal pressure is increased, by the user sucking on a mouth piece.
