    Abstract: A lighter integral with a smoking article includes a gas burner and a tube for receiving a smokable material, such as a cigarette. The gas burner generates a stable pre-mixed flame that is used to heat the material to be smoked. The smokable material may be separated from the heat source, such as a flame or a catalyst bed, by a barrier that allows heat to flow between the heat source and an interior portion of the tube. Various configurations of barriers are provided. Furthermore, an attachment is provided that allows for the conversion of a conventional lighter into a lighter that may be integrally combined with a smoking article.

  • Patent number: 5417227
    Abstract: A smoker's pipe (10) has a section (22) which is rotatable relative to a section (66). A combustion chamber is formed by and between the two sections (22, 66). A tobacco holder (36) or a cigarette (C) is located within the pipe(10). A movable portion of a lighter unit (44) is moved axially inwardly of the pipe (10) while a mouthpiece (12) at the opposite end of the pipe (10) is within the user's mouth. This movement of the lighter unit part creates a flame (F) which is directed axially inwardly into the pipe bowl, to ignite the tobacco (T) within the tobacco holder (36) or a cigarette (C) in place of the tobacco holder (36). When it is desired to extinguish combustion, pipe section (22) is rotated relative to pipe section (66). This closes off air supply openings (16) and air supply passageways (42). The user can continue smoking the pipe (10) until combustion is completely extinguished.

    Abstract: A device including a housing, a mouthpiece, a bellows, and an igniter is provided to contain secondary smoke. A cigarette may be sealed in the housing of the device and lit by the igniter. Once the cigarette is lit, when a smoker draws a breath through the mouthpiece, air is drawn through the lit cigarette and the resulting smoke-ladened air from the cigarette passes into the smoker's mouth. If the smoker then exhales into the device, the exhaled smoke is conducted to the bellows. The secondary smoke, thus trapped in the bellows, may later be released where it is safe and permissible to do so.
