Abstract

Claims (31)

1 . An aerosol delivery device, comprising:

a housing;

a first aerosol forming unit comprising:

a first chamber configured to contain a first liquid composition; and

a first metering orifice in fluid communication with the first chamber, wherein the first metering orifice comprises a first metering valve configured to selectively release the first liquid composition from the first chamber and deliver the first liquid composition to a first nozzle, the first nozzle comprising a first orifice that is configured to aerosolize the first liquid composition in the absence of heating such that the aerosol comprises particles of a first average size range;

a second aerosol forming unit comprising:

a second chamber configured to contain a second liquid composition; and

a second metering orifice in fluid communication with the second chamber wherein the second metering orifice comprises a second metering valve configured to selectively release the second liquid composition from the second chamber and deliver the second liquid composition to a second nozzle, the second nozzle comprising a second orifice that is configured to aerosolize the second liquid composition in the absence of heating such that the aerosol comprises particles of a second average size range that is different from the first average size range.

2 . The aerosol delivery device of claim 1 , wherein the first metering orifice is configured to generate an aerosol with sufficiently small particle size for pulmonary administration.

3 . The aerosol delivery device of claim 2 , wherein the first metering orifice is configured to generate an aerosol with an average particle size in the range of about 0.05 microns to about 5 microns.

4 . The aerosol delivery device of claim 1 , wherein the second metering orifice is configured to generate an aerosol with sufficiently large particle size to predominately avoid pulmonary administration.

5 . The aerosol delivery device of claim 4 , wherein the second metering orifice is configured to generate an aerosol with an average particle size in the range of about 1 micron to about 50 microns.

6 . The aerosol delivery device of claim 1 , wherein the first liquid composition and the second liquid composition both comprise a propellant.

7 . The aerosol delivery device of claim 1 , wherein at least one of the first liquid composition and the second liquid composition further comprise a vapor pressure adjusting solvent.

8 . The aerosol delivery device of claim 1 , wherein at least one of the first liquid composition and the second liquid composition further comprise a surfactant.

9 . The aerosol delivery device of claim 1 , wherein at least one of the first liquid composition and the second liquid composition further comprise one or more other ingredients.

10 . The aerosol delivery device of claim 1 , wherein the first liquid composition further comprises an active ingredient.

11 . The aerosol delivery device of claim 10 , wherein the active ingredient is selected from the group consisting of nicotine, stimulants, pharmaceutical ingredients, nutraceutical ingredients, medicinal ingredients, and botanical ingredients.

12 . The aerosol delivery device of claim 1 , wherein the second liquid composition further comprises at least one flavor compound.

13 . The aerosol delivery device of claim 1 , wherein the first metering orifice and the second metering orifice are configured to be activated simultaneously.

14 . The aerosol delivery device of claim 1 , wherein the device further comprises an externally accessible activation element configured to provide for manual activation the device for release of an aerosol.

15 . The aerosol delivery device of claim 14 , wherein the device further comprises a controller, and wherein manual activation of the device with the externally accessible activation element causes the controller to direct the release of an aerosol.

16 . The aerosol delivery device of claim 1 , wherein the device further comprises a puff-activation element configured to provide for release of an aerosol when a user draws on the device.

17 . The aerosol delivery device of claim 16 , wherein the puff-activation element comprises a pressure sensor configured to measure differential pressure in the device.

18 . The aerosol delivery device of claim 17 , wherein the device further comprises a controller in direct communication with the pressure sensor, and wherein the puff-activation element causes the controller to direct release of the aerosol.

19 . The aerosol delivery device of claim 1 , further comprising a power source and one or more control components.

20 . The aerosol delivery device of claim 1 , wherein the pressure within the first chamber and pressure within the second chamber are independently greater than ambient pressure.

21 . The aerosol delivery device of claim 1 , wherein the pressure within the first chamber and the pressure within the second chamber are within the range of about 25 psi to about 150 psi.

22 . The aerosol delivery device of claim 1 , further comprising a mouthpiece portion positioned to receive the aerosol from the first and second metering orifices and having an opening for egress of the aerosol from the mouthpiece portion.

23 . The aerosol delivery device of claim 22 , further comprising one or more channels positioned between the first and second metering orifices and the mouthpiece portion.

24 . The aerosol delivery device of claim 23 , wherein the device comprises a first channel configured to transfer the aerosol from the first metering orifice to the mouthpiece portion and a second channel configured to separately transfer the aerosol from the second metering orifice to the mouthpiece portion.
