    摘要： A cigarette includes an ignition element in contact with tobacco, surrounded by a composite outer wrapper. The outer wrapper is impervious to oxygen causing the tobacco to extinguish between puffs. The ignition element, however, has a longer static burn time than the tobacco and remains smoldering between puffs. Upon a subsequent puff, the smoldering ignition element re-ignites the tobacco. One or more initially-occluded perforations in the outer layer maintain the uniformity in combustion of the tobacco and ignition element.

    摘要： A smoking article comprises a smoking accessory and a cigarette. The smoking accessory includes a holder and a substantially air-impermeable sleeve which is coupled to a distal portion of the holder and is coaxial therewith. The cigarette is received in the smoking accessory such that a distal end of the cigarette is located substantially flush with a distal end of the sleeve. The cigarette includes a column of tobacco which is shorter than that used in conventional cigarettes, e.g., 20 mm in length or less. An air gap separates an outer surface of the cigarette from the sleeve, and plural openings are formed in the sleeve to supply air to the cigarette. In use, the sleeve restricts the flow of air to the cigarette, thereby slowing combustion and reducing sidestream smoke between puffs.

    摘要： The present invention relates to a process for producing a tasteless carbon heat source from a preformed article of a ligno-cellulosic material according to which the article is pyrolyzed in a continuously exchanged inert atmosphere at a temperature within the range of from about 800.degree. to about 1100.degree. C., for from about 0.5 to about 3 hours, then cooled in the inert atmosphere at a rate of from about 500.degree. to about 10.degree. C. per hour to a temperature within the range of from about 275.degree. C. to about 25.degree. C., and then subjected to at least one additional process step selected from an oxygen absorption step, a salt impregnation followed by heat treatment step, and a water desorption step. The present invention also relates to a smoking article including the carbon heat source, and a flavor generator comprising a substrate material containing at least one thermally releasable flavorant.

    摘要： An improved process for expanding tobacco is disclosed wherein tobacco components such as stems, midribs and veins are contacted with an alkaline-hydrogen peroxide solution to effect expansion, washed and then dried and/or roasted to produce an expanded tobacco material highly suitable for use in smoking products. Prior to contact with the alkaline hydrogen peroxide solution, the tobacco materials are subjected to a pretreatment step with gaseous ozone to prevent clumping and/or interadherence of the tobacco shreds which would otherwise occur during the drying step.
