ABSTRACT:
Mechanism for attaching a valve assembly to a pressurized container having a neck closed by a puncturable diaphragm and surrounded by a radially outwardly extending circumferential rim. The mechanism includes a body portion having a partial skirt with an inward arcuate lip to engage beneath one side of the circumferential rim of the container and a central upstanding boss which is internally threaded to receive the threaded stem of the valve assembly. A locking arm is pivotally received on the central boss and has a downwardly displaced inwardly extending lip to engage beneath the circumferential rim of the container. In the normal position of the locking arm, its lip is radially spaced less than 180.degree. from an opposite end of the arcuate lip of the body to define an entrance opening for receiving the rim of the container therethrough. The locking arm is resiliently movable outward from the body, so that the mechanism can be manually forced edgewise over the container rim to carry the arm lip and opposite end of the arcuate lip past diametrically opposite positions on the container rim to lock the mechanism to the container. The locking arm can then be swung toward the opposite end of the arcuate lip to close the entrance and secure the attachment mechanism in place on the neck of the container.
