Abstract

A smoking device for generating and releasing smoking vapor free from contamination into the mouth of a user comprising a mouthpiece for providing vapor for inhalation to a user including a tubular casing containing a heater for heating a smoking substance at a substantially constant low temperature by regulating the flow of fuel by a thermal regulator and further having means for visual indication of the operation of the device.

Claims

1. A cartridge for use in a smoking device comprising:

a wrapper containing a smokeable material comprising a vapor forming medium and fine pieces of tobacco material wherein all of the fine pieces of tobacco have a diameter of less than 3 mm; and

at least one perforation in the top of the wrapper, through which at least one aeration well is created in the tobacco, wherein tobacco is arranged between a bottom of the aeration well and a bottom of the cartridge, and wherein the at least one perforation allows an exit of an inhalable vapor generated from heating, without burning, the smokeable material.

2. The cartridge of claim 1, wherein the wrapper comprises aluminum.

3. The cartridge of claim 1, wherein the smokeable material vaporizes when heated to a temperature required to vaporize the smokeable material.

4. The cartridge of claim 3, wherein the temperature is below 400 F.

5. The cartridge of claim 3, wherein the cartridge is configured to be inserted into a device wherein the device is capable of vaporizing the smokeable material.

6. The cartridge of claim 5, wherein the cartridge is configured to be inserted into a vaporization chamber of the device.

7. The cartridge of claim 5, wherein the vapor forming medium comprises glycerine.

8. The cartridge of claim 1, wherein the smokeable material is moist.

9. A cartridge for use in a smoking device comprising:

a wrapper containing a smokeable material comprising a vapor forming medium and fine pieces of tobacco material wherein all of the fine pieces of tobacco have a diameter of less than 3 mm; and

at least one perforation in the top of the wrapper, through which at least one aeration well is created in the tobacco, wherein tobacco is arranged between a bottom of the aeration well and a bottom of the cartridge, and wherein the at least one perforation allows an exit of an inhalable vapor generated from heating, without burning, the smokeable material, and

wherein the cartridge is enclosed on all surfaces except the one surface with the at least one perforation.

10. A cartridge for use in a smoking device comprising:

a wrapper containing a smokeable material comprising a vapor forming medium and fine pieces of tobacco material wherein all of the fine pieces of tobacco have a diameter of less than 3 mm; and

at least one aeration well in the tobacco material that extends from a top of the wrapper, wherein tobacco is arranged between a bottom of the aeration well and a bottom of the cartridge, and wherein the aeration well is aligned with a perforation to be made in the top of the wrapper in order to provide aeration of an inhalable vapor generated from heating, without burning, the smokeable material.
