ABSTRACT:
A pressurized liquid dispensing container and valve assembly comprises an essentially upright container for containing under pressure a liquid to be dispensed and a discharge valve assembly above the container. The valve assembly includes a valve body and a nozzle having a discharge opening that is controlled by a valve. The valve includes a frustoconical valve seat formed in an end wall of the nozzle, and a frustoconical valve head which is axially movable between an inward seating position and an outward position in which the valve is open. A protective cap is screw threaded on the outside of the nozzle and has a discharge aperture in its outer end wall. The valve head has an outer end surface that normally abuts against an inside surface of the cap so as to restrict flow from the nozzle through the discharge aperture in the cap. The cap when screwed tightly holds the valve closed. Partial unscrewing of the cap adjusts the amount of valve opening and rate of liquid discharge. By partial unscrewing of the cap, one can obtain either a spray or a steady stream of liquid.
