  • Patent number: 5396907
    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.
