초록

An apparatus and method for discharging liquids such as vapocoolants in stream or mist form includes the use of a filter to remove contaminants from the liquid prior to dispensing through the nozzle opening. A streamlined flow of liquid is delivered to the nozzle to prevent after spray and the filter spaced from the nozzle to inhibit pulsation of the dispensed liquid stream. The filter and nozzle are provided as an assembly mounted in a passageway in the container actuator.
