Abstract:
1. A self-contained, hand-held spray dispensing device for dispensing one or more liquid material(s), the dispensing device comprising: a container having a discharge port for each material, each container having a liquid ejecting element associated therewith, each liquid ejecting element being connectable to a force transmitting yoke having a working surface thereon, each container being responsive to a force imposed by the liquid ejecting element thereby to cause a liquid material in that container to be ejected from the discharge port, a housing; a first and a second liquid discharge line disposed within the housing, each liquid discharge line having an inlet end and an outlet end; a container support arrangement able to receive and to support a first and a second liquid container within the housing such that the discharge port of each container is disposed in fluid communication with the inlet end of a liquid discharge line; an actuator disposed within the housing, the actuator being operative to apply a motive force to a working surface of a yoke receivable within the actuator; a cartridge support arrangement disposed within the housing, the cartridge support arrangement being able to receive and to support a cartridge holding a pressurized fluid; a first pressurized fluid line able to convey a pressurized fluid from a cartridge receivable within the housing into the actuator; a valve able to control the flow of a pressurized motive fluid through the pressurized fluid line; and a trigger operatively associated with the valve, the trigger being movable from a rest position to a first operational position, when in the first operational position the trigger being operative to open the valve to permit a pressurized motive fluid from a cartridge receivable within the housing to flow through the pressurized fluid line into the actuator to generate a motive force on the working surface of a yoke receivable within the actuator, thereby to cause each liquid ejecting element to eject a liquid in the container through the discharge port thereof; a second pressurized fluid line able to convey a pressurized fluid from a cartridge receivable within the housing over the outlet end of each liquid discharge line, the valve also able to control the flow of a pressurized fluid through the second pressurized fluid line; and the trigger, when in the first operational position, being operative to control the valve to permit a pressurized fluid to flow through the second pressurized fluid line, whereby a flow of pressurized fluid is able to pass over the outlet ends of the liquid discharge lines to generate an aerosoling action on any liquid material emanating from the outlet ends of the liquid discharge lines.
