ABSTRACT:
A hollow body has a connected tubular discharge stem. The stem has a tapered tip formed with at least one discharge passage. An annular gasket complementing the shape of the taper is normally seated on the tip and valves off the passage. A hollow tubular shell is over the stem and carries the gasket at its upper end. The shell encloses a spring working between the bottom of the shell and a fin on the stem spaced back from the tip. In operation, the shell is moved away from the body so liquid can discharge through the gasket.
