  • Publication number: 20100108084
    Abstract: A filtered cigarette includes a smokable rod and a filter element. The smokable rod is secured to the filter element using tipping material. The tipping material includes at least one flavorant providing a sensory characteristic. The cigarette may include more than one layer of tipping material. An outer layer of tipping material can overlie at least a portion of an underlying inner layer of tipping material, and during use by the smoker, the outer layer can be removed from the cigarette. Thus, it is possible for a cigarette manufacturer to provide a cigarette that can be used as such by the smoker, or that can be adapted by the smoker to provide a different sensory experience (e.g., the visual, organoleptic, trigeminal, aromatic, and tactile characteristics of the cigarette can be altered by removal of the outer tipping material, and or by provision of a tipping material layer that is treated with a flavorant and/or provides a desirable diffusivity).

  • Patent number: 5159944
    Abstract: A cigarette includes a charge or roll of smokable material (e.g., tobacco cut filler) circumscribed by two layers of paper wrapping materials. The first or inner wrapping material includes a cellulosic base web and carbonaceous material within the web. The second or outer wrapping material circumscribes and overwraps the first wrapping material, has a cellulosic base web and inorganic filler material, and exhibits an air permeability of below about 8 CORESTA units. The cigarette is capable of sustaining smolder under FTC smoking conditions while yielding very low levels of visible sidestream smoke.

  • Patent number: 5092353
    Abstract: Cigarettes which yield very low levels of sidestream "tar" during use comprise a paper wrapper having an air permeability of less than about 10 CORESTA units, and a blend of a tobacco filler material and a second smokable material. The second smokable material preferably includes about 60 weight percent calcium carbonate, about 30 weight percent pyrolyzed alpha-cellulose and about 10 weight percent carboxymethyl cellulose. Such cigarettes, when used, generate very low amounts of sidestream "tar", and hence, very low levels of visible sidestream smoke.

  • Patent number: 5067499
    Abstract: The present invention relates to fuel elements useful in smoking articles which produce an aerosol that resembles tobacco smoke, but contains no more than a minimal amount of incomplete combustion or pyrolysis products.Preferred embodiments of the present invention comprise a short combustible carbonaceous fuel elements, usually less than about 20 mm in length, preferably from about 5 to 15 mm in length, and most preferably about 10 mm in length. The diameter of the fuel elements of the present invention generally is less than about 8 mm, preferably from about 3 to 7 mm, and most preferably from about 4 to 6 mm.Smoking articles utilizing the fuel elements of the present invention are capable of providing an aerosol "smoke" which is chemically simple, consisting essentially of air, oxides of carbon, water, and the aerosol which carries any desired flavorants or other desired volatile materials, and trace amounts of other materials.

  • Patent number: 5020548
    Abstract: The present invention preferably relates to a smoking article which is capable of producing substantial quantities of aerosol, both initially and over the useful life of the product, without significant thermal degradation of the aerosol former and without the presence of substantial pyrolysis or incomplete combustion products of sidestream aerosol. The article of the present invention is able to provide the user with the sensations and benefits of cigarette smoking without the substantial combustion products produced by burning tobacco in a conventional cigarette. In addition, the article may be made virtually ashless so that the user does not have to remove any ash during use.
