  • Patent number: 6532965
    Abstract: A non-burning cigarette holder is comprised of an upstream cylindrical section of a low heat conducting material and a downstream cylindrical section of a relatively high heat conducting material. The upstream cylindrical section has a first upstream chamber for receiving a fuel source and a second downstream chamber defining a fuel mixture chamber which is in flow communication with the first upstream chamber. The downstream cylindrical section is provided with a flame holder downstream of the chamber and a flame chamber is disposed between the flame holder and a cigarette receiving chamber adapted to receive a tobacco rod or a cigarette. The fuel source may be an ethanol-water mixture disposed within the upstream cylindrical section or the fuel source may be attached to the upstream end of the upstream cylindrical section.

  • Patent number: 4765348
    Abstract: A non-combustible simulated cigarette inhaler device includes a hollow cylindrical tube having an open air inlet end and an opposed open air outlet end to be placed in the mouth of a user. A first element of air permeable material is located within the hollow tube across a segment of the transverse cross-sectional area of the tube and a second element of air permeable material is located within the hollow tube across the remaining segment of the transverse cross-section of the tube. The first element is impregnated with a nicotine free base material. The second element is impregnated with an acid which is reactive with the free base to form a salt having a pH in the range of approximately 5 to 7. Examples of such acids are 2-butenoic acid, 2-methyl-2-butenoic acid, isocaproic, caproic, and caprylic acids.
