Abstract
Apparatus having a valve for a container intended to hold liquid. The valve includes an inner conduit which can be easily assembled through flexible fingers of an outer sleeve. The inner conduit both moves axially relative to the outer sleeve between open and closed positions and circumferentially so that the inner conduit can be threaded with respect to a mating hose. A tab which functions to stop the valve in the closed position, as well as in the open position, includes tamper-evident structure.
