  • Publication number: 20120060853
    Abstract: 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.

  • Patent number: 7856990
    Abstract: A filter element incorporating an adsorbent material is provided. The filter element may comprise a first section of filter material and a second section of filter material spaced apart to form a compartment therebetween. The compartment may be filled with one or more adsorbents or the compartment may be divided into two regions, wherein one compartment region is filled with an adsorbent and the other compartment region is either filled with an ion-exchange resin or remains empty. The section of filter material adjacent to the tobacco rod may include one or more channels therethrough for passaging smoke directly from the tobacco rod into the adsorbent-filled compartment. The mouth end section of filter material may contain a breakable capsule, wherein the breakable capsule is filled with a flavoring agent capable of altering the taste characteristics of mainstream smoke.

  • Patent number: 5685323
    Abstract: A disposable filter attachment for smoking articles, such as cigarettes, comprises first and second filter segments and an insertion tube at one end thereof for receiving and supporting a conventional filtered or unfiltered cigarette to be smoked. The first filter segment contains a carbonaceous material for removing gas phase components of the mainstream cigarette smoke. The total pressure drop across the filter attachment is very low, e.g., less than about 15 mm of water at 17.5 cc/sec air flow and preferably in the range of about 3 mm to about 12 mm of water at 17.5 cc/sec air flow.
