Abstract:
1. A modular coupling system for pressurized gas containers, said containers comprising an integral flow regulator, the coupling system comprising a first coupler part adapted to be fixedly secured to a pressurized gas container in a substantially non-removable manner and a second coupler part adapted to be fixedly secured to, or integrally formed with, a gas utilizer device or equipment such as a flow meter, conservor or other delivery apparatus, the first coupler part being provided with valve closure means and the coupling system having venting means allowing escape of trapped pressurized gas upon removal of a gas utilizer device or equipment from a pressurized gas container before separation of the first and second coupler parts takes place, and the first coupler part has a gas delivery valve resiliently biased to a closure position, the gas delivery valve having a valve-operating member engaged in use by the second coupler part upon coupling together of the first and second coupler parts, and the first and second coupler parts have a common axis and the valve-operating member is displaceable transversely thereof to effect opening or closure of the gas delivery valve as the first and second coupler parts are turned with respect to one another about the common axis.
