ABSTRACT:

The plungers is connected to a manually operable cap containing a return spring, and the cap has a rim with a pair of internal barbs which engage an external flange on the body when the cap is fully depressed, to latch the valve open. A pair of flats on the cap rim are squeezed together in order to release the latch.
