Abstract

Provided herein is a composition for use in a device for generating an inhalable medium, the composition including (a) 20-40% by weight of air-cured and/or fire-cured tobacco, (b) 0-35% by weight of flue-cured and/or sun-cured tobacco that has not been subjected to any further treatment which affects the flavor properties of tobacco, and (c) 25-80% by weight of flue-cured and/or sun-cured tobacco that has been further treated to enhance the flavor properties of tobacco.

Claims

1. A composition for use in a device for generating an inhalable medium, the composition comprising:

about 20-40% by weight of a first material comprising at least one of an air-cured tobacco and a fire-cured tobacco;

about 0-35% by weight of a second material comprising at least one of a flue-cured tobacco that has not been subjected to any further treatment which affects the flavor properties thereof and a sun-cured tobacco that has not been subjected to any further treatment which affects the flavor properties thereof, and

about 25-80% by weight of a third material comprising at least one of a flue-cured tobacco that has been further treated to enhance the flavor properties thereof and a sun-cured tobacco that has been further treated to enhance the flavor properties thereof.

2. The composition of claim 1 comprising 15-35% by weight of the second material and 25-65% by weight of the third material.

3. The composition of claim 1 comprising 25-35% by weight of the first material, 20-30% by weight of the second material, and 35-55% by weight of the third material.

4. The composition of claim 1 comprising 35-40% by weight of the first material, 30-35% by weight of the second material, and 25-35% by weight of the third material.

5. The composition of claim 1 comprising both air-cured tobacco and fire-cured tobacco, wherein the weight ratio of air-cured tobacco to fire-cured tobacco is from about 3:

1 to about 1;

3.

6. The composition of claim 1, wherein the third material comprises tobacco that has been exposed to a processing temperature at least about 45°

C. while positioned in a moisture-retaining material at a packing density on a dry weight basis of at least 200 kg/m³ at the start of the process, and wherein the third material has a moisture content of between about 10% and about 23%.

7. The composition of claim 6, wherein the third material has undergone a Maillard reaction.

8. The composition of claim 1 comprising air-cured tobacco, fire-cured tobacco and flue-cured tobacco that has not been subjected to any further treatment which affects the flavor properties thereof.

9. The composition of claim 8 comprising at least one of dark air-cured tobacco and dark fire-cured tobacco.

16. The composition of claim 1 comprising both air-cured tobacco and fire-cured tobacco, wherein the weight ratio of air-cured tobacco to fire-cured tobacco is from about 2:

1 to about 1;

2.

10. A device for generating an inhalable medium,

the device comprising:

a container configured to hold a liquid;

a heater configured to volatilize the liquid held in the container;

a chamber containing a tobacco composition comprising;

about 20-40% by weight of a first material having at least one of an air-cured tobacco and a fire-cured tobacco;

about 0-35% by weight of a second material comprising at least one of a flue-cured tobacco that has not been subjected to any further treatment which affects the flavor properties thereof and a sun-cured tobacco that has not been subjected to any further treatment which affects the flavor properties thereof; and

about 25-50% by weight of a third material comprising at least one of a flue-cured tobacco that has been further treated to enhance the flavor properties thereof and a sun-cured tobacco that has been further treated to enhance the flavor properties thereof; and

an outlet;

wherein the container, the heater, the chamber, and the outlet are arranged such that, in use, an inhalable medium passes out of the outlet, the inhalable medium comprising one or more constituents of the tobacco composition and volatilized liquid in the form of at least one of a vapor and an aerosol.

11. The device of claim 10,

wherein the container, the heater, the chamber, and the outlet are arranged such that, in use, liquid volatilized by the heater passes, in the form of at least one of a vapor and an aerosol, through the tobacco composition to thereby entrain one or more constituents from the tobacco composition to produce the inhalable medium which passes out of the outlet.

12. A cartridge for use in a device for heating tobacco material, the cartridge containing a tobacco composition comprising:

about 20-40% by weight of a first material having at least one of an air-cured tobacco and a fire-cured tobacco;

about 0-35% by weight of a second material comprising at least one of a flue-cured tobacco that has not been subjected to any further treatment which affects the flavor properties thereof and a sun-cured tobacco that has not been subjected to any further treatment which affects the flavor properties thereof; and

about 25-50% by weight of a third material comprising at least one of a flue-cured tobacco that has been further treated to enhance the flavor properties thereof and a sun-cured tobacco that has been further treated to enhance the flavor properties thereof.

13. The cartridge of claim 12, comprising (i) a liquid container which includes a liquid comprising nicotine and optionally one or more of an aerosol generating agent and a flavoring, and (ii) a chamber in which the tobacco composition is provided.

14. A method of generating an inhalable medium using an apparatus comprising a container holding a liquid, a heater for volatilizing the liquid, a tobacco composition and an outlet, the method comprising:

volatilizing the liquid held in the container;

forming an inhalable medium, the inhalable medium comprising (a) the volatilized liquid in the form of at least one of a vapor and an aerosol and (b) one or more constituents of a tobacco composition comprising;

about 20-40% by weight of a first material having at least one of an air-cured tobacco and a fire-cured tobacco;

about 0-35% by weight of a second material comprising at least one of a flue-cured tobacco that has not been subjected to any further treatment which affects the flavor properties thereof and a sun-cured tobacco that has not been subjected to any further treatment which affects the flavor properties thereof; and

about 25-50% by weight of a third material comprising at least one of a flue-cured tobacco that has been further treated to enhance the flavor properties thereof and a sun-cured tobacco that has been further treated to enhance the flavor properties thereof; and

passing the inhalable medium out of the outlet.

15. The method according to claim 14 further comprising:

entraining one or more constituents from the tobacco composition in at least one of a vapor and an aerosol formed by the volatilized liquid by passing the at least one of a vapour and an aerosol through the tobacco composition to generate the inhalable medium; and

passing the inhalable medium out of the outlet.
