Publication number: 20120060853Abstract: A smoking article may include a cigarette incorporated within an electrically powered aerosol generating device that acts as a holder for that cigarette. The smoking article possesses at least one form of tobacco. The smoking article also possesses a mouth-end piece that is used by the smoker to inhale components of tobacco that are generated by the action of heat upon components of the cigarette. A representative smoking article possesses an outer housing incorporating a source of electrical power (e.g., a battery), a sensing mechanism for powering the device at least during periods of draw, and a heating device (e.g., at least one electrical resistance heating element) for forming a thermally generated aerosol that incorporates components of tobacco. During use, the cigarette is positioned within the device, and after use, the used cigarette is removed from the device and replaced with another cigarette.Type: ApplicationFiled: November 16, 2011Publication date: March 15, 2012Inventors: John Howard Robinson, David William Griffith, JR., Billy Tyrone Conner, Evon Llewellyn Crooks, Dempsey Bailey Brewer, JR.
