Abstract: 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.
Abstract: An apparatus and method for discharging vapocoolants in stream or mist form includes the use of selected fluoroelastomers for valve parts to regulate discharge. The fluoroelastomers provide long-term stability to the vapocoolants to enable superior shelf life without minimal loss or contamination of the vapocoolant. In addition, a filter is provided to remove contaminants from vapocoolant prior to passage through the nozzle opening.
