Patent ID: 8870090

Claim:
A volatile liquid droplet dispenser device for connection with a reservoir containing a liquid substance to be dispensed, the device comprising: (a) a first substrate having a space for containing said liquid substance; (b) liquid outlet means for ejecting liquid substance from said device, wherein said space is arranged proximate to said liquid outlet means so that liquid substance may exit the space of the device by traversing said liquid outlet means; (c) a second substrate containing connection means arranged to receive said reservoir, and having a liquid inlet means for allowing said liquid substance to enter said device from said reservoir; and (d) an actuating element arranged on the liquid outlet means to cause vibration of liquid substance in said space so that vibrating liquid substance contacts the liquid outlet means and then exits said device as a liquid droplet spray generated by vibration, wherein the liquid outlet means of said first substrate comprises a perforated nozzle membrane having a plurality of outlet nozzles, wherein said first substrate contains at least one fluidic capillary priming channel arranged to receive said liquid substance from said space so as to fill the channel so that said liquid substance is in close proximity to said outlet nozzles for priming said liquid substance for ejection through said nozzle membrane, and wherein said at least one fluidic capillary priming channel is formed directly in said nozzle membrane of the liquid outlet means of said first substrate.
