  • Gas container, a coupling for a gas container, and a method of making a gas container
    Patent number: 5082243
    Abstract: A coupling connects a valve structure to a container for enclosing pure gas under high pressure. The neck of the container and the valve structure include cooperating contact surfaces. One of the contact surfaces is convexly curved, or alternatively is of frusto-conical shape. The other of the contact surfaces is of convex spherical shape. A sealing ring is compressed between those contact surfaces. The inner surface of the container is polished to achieve a high degree of smoothness. The container is formed of a top part, and a bottom portion welded to an intermediate mantle.
