The spray can has a liquid delivery tube for conducting liquid to be dispensed to an outlet and a selectively controllable interruption plunger for preventing liquid dispensing flow from the spray can. The plunger, for selectively preventing liquid flow, is independent from the finger-pressure spray can dispensing valve.
