Abstract
Disposable smoking devices disclosed in a variety of pipe, cigarette or cigar configurations, and designed to totally suppress the inhalation by the user of the toxic substances contained in tobacco smoke. This goal is achieved by keeping the air-intake channel separated from the combustion chamber by a fire-resistant, but heat-conductive wall and by depositing on the channel-side of this wall nicotine and other tobacco-simulating substances in a volatile or sublimable form whose vapors only are inhaled; thus giving the user the same sensations as a common pipe, cigar or cigarette, but free of the deleterious effects inherent to the absorption of tobacco smoke. The air intake channel may be located either in the center of the combustion chamber or along its periphery.
Claims25
A smoking device which comprises:
- a combustion chamber;
- combustible material held within said chamber;
- a mouth piece;
- an air-intake conduit connected to said mouth piece, said conduit having an area contiguous to said combustion chamber but separated from it by a heat-conductive wall, shaped and dimensioned to prevent smoke generated in said combustion chamber from entering said conduit and mouth piece means allowing temporary passage of air between the combustion chamber and the air intake conduit during the initial lighting of the smoker's device via an aperture shaped and positioned in said wall;
A smoking pipe comprising:
- a bowl;
- a mouth piece;
- a stem connecting the bowl to the mouth piece;
- said stem and said mouth piece having a channel therethrough in communication with the inside of said bowl;
- a separable, heat-resistant cupule inserted within said bowl, said cupule suitable for holding combustible material and acting as a combustion chamber and wherein said cupule has at least an aperture shaped and positioned to allow temporary passage of air between the combustion chamber and said channel during the initial lighting of the smoking pipe;
- means for drawing air around the periphery of said cupule and through said channel wherein said aperture is not in position to allow temporary passage of said air;
- and
- volatile substances applied against the outside walls of said cupule.
