<p>A fluid container adapted to contain fluid under pressure, has a discharge outlet normally closed by a frangible diaphragm which is supported by a member held in a position at which it prevents bursting of the diaphragm by pressure within the container. A rotary member is coupled to the diaphragm-supporting member, and means are provided for effecting selective rotation of the rotary member, to free the diaphragm supporting member to move away from the supporting position whereby the diaphragm is no longer supported against bursting.</p> |
