  "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 method of creating an impression of smoking comprising: deploying a device comprising a casing and a mouthpiece, wherein the casing is removably attached to the mouthpiece, wherein the device generates a smokeless vapor by heating a substance housed entirely in the casing, the substance containing a tobacco material and glycerine; heating the substance to a target temperature to generate a vapor having impression of smoke from the substance; and inhaling the vapor from the mouthpiece at a draw rate from the device that creates the impression of smoking, wherein the draw rate is restricted by an air inlet on the mouthpiece, wherein the air inlet transports fresh air from the mouthpiece to the substance in the casing.",
    "2. The method of claim 1, wherein the heat is provided by a butane fuel heater.",
    "3. The method of claim 1, wherein the heat is provided by an electric heater.",
    "4. The method of claim 3, wherein the electric heater is a battery-powered electric heater.",
    "5. The method of claim 1, wherein the target temperature is maintained at a preselected temperature.",
    "6. The method of claim 5, wherein the preselected temperature is selected according to the vaporization temperature of the tobacco material.",
    "7. The method of claim 1, wherein the target temperature is below 400 degrees F.",
    "8. The method of claim 1, wherein the target temperature is below 350 degrees F."

  "description_excerpt": "1. Field of the Invention\n\nThe present invention is directed to improvements in smoking devices, particularly to smoking articles which employ a formed tobacco cartridge as a source of producing vapor by heat transfer to the cartridge by conduction, convection, and radiation for smoke and flavor. The present invention relates to self-contained vaporization devices, and more particularly, to a low-temperature vaporization device for use of tobacco product. The device is of an elongated main body with a mouthpiece at one end and an attached tubular casing at the other end having a vaporization chamber and a heater. The mouthpiece and the casing form an unitary unit.\n\n2. Description of the Related Art\n\nSmoking devices, such as cigarette holders and pipes are well known in the art for providing flavored vapor from a smokeable substance to a user for therapeutic and smoking pleasure. However, existing devices used have no control of heating and combustion of the tobacco products. The devices tend to produce toxic, tarry and carcinogenic by-products which are harmful and also impart a bitter and burnt taste to a mouth of a user.\n\nA further problem is that there is no control of contamination of the inhaled vapor mixture with heater exhaust gases, due to inappropriate proportioning and location of the inlets and the exhaust vents. Typically, the exhaust gas is used to directly heat the tobacco, and those gases contain harmful byproducts of incomplete combustion.",
