ABSTRACT:
A hermetically sealable fluid containment assembly is provided. Fluids, such as compressed gases, are typically stored in a base container having a shoulder with a neck projecting outwardly from the shoulder. In accordance with the invention, a collar member generally surrounds the neck and rests upon the shoulder of the base container. A locking arrangement is provided to securely fasten the collar member to the base container. A closure member in the form of a protective cap engages the collar member. To prevent the leakage of fluid between the collar and the base container, a seal is provided between respectively engaging surfaces of the base container and the collar. The leakage of gas between the collar member and the closure member is also prevented by a second seal disposed between respective engaging surfaces of the closure member and the collar member.
