摘要：Mechanism for attaching a valve assembly to a pressurized container having aneck closed by a puncturable diaphragm and surrounded by a radially outwardlyextending circumferential rim. The mechanism includes a body portion having a partialskirt with an inward arcuate lip to engage beneath one side of the circumferential rim ofthe container and a central upstanding boss which is internally threaded to receive thethreaded stem of the valve assembly. A locking arm is pivotally received on the centralboss and has a downwardly displaced inwardly extending lip to engage beneath thecircumferential rim of the container. In the normal position of the locking arm, its lip isradially spaced less than 180. degree. from an opposite end of the arcuate lip of thebody 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 canbe manually forced edgewise over the container rim to carry the arm lip and oppositeend of the arcuate lip past diametrically opposite positions on the container rim to lockthe mechanism to the container. The locking arm can then be swung toward the oppositeend of the arcuate lip to close the entrance and secure the attachment mechanism inplace on the neck of the container.
