Aerosol devices and methods for inhaling a substance and uses thereof
Devices, cartridges, and method are described herein for emulating smoking wherein a device generates an aerosol for inhalation by a subject by heating a viscous material that can have a tactile response in the mouth or respiratory tract, while reducing Hoffman analytes and mutagenic compounds delivered to the user as compared to a common tobacco cigarette.
1. A device for aerosolizing a material comprising:
a body including a heater;
a vaporizable material contained in a cartridge; and
a lid sealed upon the cartridge, wherein the lid comprises apertures or vents;
wherein the vaporizable material comprises propylene glycol, glycerin, and a tobacco material comprising pieces of tobacco;
wherein the device is configured to generate an aerosol by heating the vaporizable material to a target temperature at which the vaporizable material forms an aerosol substantially free from at least one Hoffmann analyte;
wherein the propylene glycol and glycerin are present in an amount to produce a visible aerosol; and
wherein the apertures or vents of the lid allow an exit of the aerosol generated from heating the vaporizable material.
2. The device of claim 1 , wherein the vaporizable material is a fluidic or viscous vaporizable material.
3. The device of claim 1 , wherein the cartridge comprises a flange.
4. The device of claim 3 , wherein the lid is sealed upon the flange.
5. The device of claim 1 , wherein the lid is metallic.
6. The device of claim 1 , wherein the lid comprises a heat-sealable film or aluminum.
7. The device of claim 1 , wherein the at least one Hoffmann analyte is selected from the group consisting of: ammonia, aminonaphthalenes, benzopyrene, formaldehyde, acetaldehyde, acetone, methyl ethyl ketone, butyraldehyde, hydrogen cyanide, nitrous oxides, tobacco-specific nitrosamines (TSNAs), pyridine, quinolone, hydroquinone, phenol, cresols, tar, carbon monoxide, 1,3-butadiene, isoprene, acrylonitrile, benzene, toluene, and styrene.
8. The device of claim 1 , wherein the pieces of tobacco are less than 2 mm in diameter.
9. The device of claim 1 , wherein the target temperature is 100° C. to 200° C.
10. The device of claim 1 , wherein the aerosol contains at least 70% less Hoffman analytes than a common tobacco cigarette.
11. The device of claim 1 , wherein the glycerin is present in an amount to produce a visible vapor when the aerosol is exhaled by a user.
12. A cartridge for use in a vaporizer device comprising an oven chamber configured for the cartridge to be inserted therein, the cartridge comprising:
a shell containing a vaporizable material comprising propylene glycol, glycerin, and a tobacco material comprising pieces of tobacco; and
a lid sealed upon the shell, wherein the lid comprises a plurality of apertures or vents;
wherein the plurality of apertures or vents of the lid are configured to allow exit of an aerosol generated from heating the vaporizable material within the cartridge to a target temperature by a heater of the vaporizer device; and
wherein the propylene glycol and glycerin are present in an amount to produce a visible aerosol.
13. The cartridge of claim 12 , wherein the shell comprises a flange and the lid is sealed upon the flange.
14. The cartridge of claim 12 , wherein the pieces of tobacco are less than 2 mm in diameter.
15. The cartridge of claim 12 , wherein the target temperature is 100° C. to 200° C.
16. An aerosol-generating device comprising:
a body comprising a heater and an oven chamber;
a mouthpiece connected to the body such that the mouthpiece is configured to be hinged open to provide access to the oven chamber; and
a cartridge configured to be inserted into the oven chamber, the cartridge comprising:
a shell containing a vaporizable material comprising propylene glycol, glycerin, and a tobacco material comprising pieces of tobacco, wherein the heater is configured to heat the vaporizable material within the cartridge within the oven chamber to a target temperature; and
a lid sealed upon the shell, the lid comprising a plurality of apertures or vents configured to allow exit from the cartridge of an aerosol generated by heating the vaporizable material within the cartridge;
wherein the propylene glycol and glycerin are present in an amount to produce a visible aerosol.
17. The device of claim 16 , wherein the shell comprises a flange and the lid is sealed upon the flange.
18. The device of claim 16 , wherein the pieces of tobacco are less than 2 mm in diameter.
19. The device of claim 16 , wherein the target temperature is 100° C. to 200° C.
