Abstract

A handheld hydrosol delivery device includes a canister which is at least partially filled with a liquid formulation of one or more liquids and optional particles, and one or more propellants where at least one of the liquids, propellants, particles and combinations thereof is a flavor; a pressure valve which expels at least a portion of the liquid formulation and at least a portion of the propellant from the canister while dispersing the propellant into the liquid formulation forming a consumable flavored hydrosol comprising one or more gases dispersed within the liquid formulation, through a nozzle delivering the hydrosol to a user.

First claim

What is claimed is:

1. A method of producing a consumable flavored hydrosol for oral consumption with a portable handheld flavor delivery device, the portable handheld flavor delivery device comprising at least one canister therein wherein the at least one canister includes one or more liquids and one or more propellants, the method comprising:
expelling at least a portion of the one or more liquids and at least a portion of the one or more propellants from the at least one canister while dispersing the one or more propellants into the one or more liquids so as to form a consumable flavored hydrosol comprising one or more gases mixed within one or more liquids;
wherein the portable handheld flavor delivery device includes a pressure valve that is activated via a pressure drop such that the one or more propellants and the one or more liquids are expelled from the pressure valve when the pressure valve is activated.

2. The method of claim 1 , wherein the portable handheld device comprises a nozzle, the method comprising applying a suction force to the nozzle to activate the pressure valve.

3. The method of claim 1 , wherein the portable handheld device includes a flow sensor and a controller, the method further comprising sensing air flow created by a pressure drop with the flow sensor, sending a signal to the controller from the flow sensor when airflow is sensed, and activating the pressure valve by sending a signal from the controller to the pressure valve.

4. The method of claim 1 , wherein the at least one canister comprises a first canister and a second canister, the method comprising expelling the one or more propellants from the first canister and expelling the one or more liquids from the second canister.

5. The method of claim 1 , wherein the portable handheld device comprises a nozzle, the method further comprising delivering the consumable flavored hydrosol through the nozzle to a consumer's mouth.

6. The method of claim 1 , comprising pressurizing a portion of the one or more liquids before expelling the one or more liquids.

7. The method of claim 1 , wherein at least a portion of the one or more propellants comprises a compressed gas.

8. The method of claim 1 , wherein at least a portion of the one or more propellants comprises a liquid that forms a gas when expelled wherein the liquid that forms a gas when expelled is dispersed into the one or more liquids.

9. The method of claim 1 , wherein the one or more liquids comprises one or more thickening agents such that the consumable flavored hydrosol comprises one or more thickening agents.

10. The method of claim 1 , wherein the one or more propellants comprises one of carbon dioxide, oxygen, nitrous oxide, air or a combination thereof.

11. The method of claim 1 , wherein the consumable flavored hydrosol comprises one or more flavor compounds, and further wherein the one or more liquids optionally comprise the one or more flavor compounds; and
(a) the one or more flavor compounds comprise one or more non-aqueous flavor compounds; and/or
(b) the one or more flavor compounds comprise one or more aqueous flavor compounds.

12. The method of claim 1 , wherein
(a) the consumable flavored hydrosol comprises one or more surfactants, and further wherein the one or more liquids optionally comprise the one or more surfactants;
(b) the consumable flavored hydrosol comprises one or more ingredients selected from the group consisting of propylene glycol alginate, lipids, proteins, extracts from yucca plants, foam stabilizers, and mixtures thereof;
(c) the consumable flavored hydrosol comprises one or more particles, and further wherein the one or more liquids comprise the one or more particles; and/or
(d) the consumable flavored hydrosol comprises a foam, a gel, an emulsion or a combination thereof.

13. The method of claim 1 , wherein the consumable flavored hydrosol comprises a flavor selected from the group consisting of ginger, juniper, wintergreen, licorice, anise, cinnamon, lemon, orange, cloves, vanilla, menthol and mixtures thereof.

14. The method of claim 1 , further comprising expelling one or more particles with the one or more liquids and the one or more propellants and dispersing the one or more particles with the one or more propellants into the one or more liquids, thus forming a consumable flavored hydrosol comprising one or more gases and one or more particles dispersed within one or more liquids.

15. The method of claim 14 , wherein the particles are solids that vaporize in the hydrosol wherein the particles add flavor to the consumable flavored hydrosol.

16. The method of claim 14 , wherein the particles are a salt that dissolves in a liquid matrix of the consumable flavored hydrosol.
