ABSTRACT:
The invention involves a pressurized package containing an aqueous latex paint which is discharged from a collapsible piston within the pressurized container by the action of a propellant under pressure, and wherein the stream of paint discharging upon opening of the valve of the container is broken up by a mechanical breaker before being discharged through the nozzle in the form of a fine spray or mist devoid of propellant. Means are provided in the form of a cap for the nozzle for reducing or substantially eliminating the space about the nozzle after use of portions of the contents of the package to prevent drying out of any paint adhering to the nozzle and thereby clogging the nozzle. The paint employed is an aqueous acrylic latex emulsion paint in which the pigment content ranges from 2% to 15%.
