  • Cigarette having reduced sidestream smoke
    Patent number: 6823873
    Abstract: 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.
    Type: Grant

    Assignee: Philip Morris USA Inc.

  • Smoking article having reduced sidestream smoke
    Patent number: 6311694
    Abstract: 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.
