Abstract:
    A cigarette (30) includes an ignition element (36) in contact with tobacco (40, 42), surrounded by a composite outer wrapper (38). The outer wrapper (38) is impervious to oxygen causing the tobacco (40, 42) to extinguish between puffs. The ignition element (36), however, has a longer static burn time than the tobacco (40, 42) and remains smoldering between puffs. Upon a subsequent puff, the smoldering ignition element (36) reignites the tobacco (40, 42). One or more initially occluded perforations (34) in the outer layer (38) maintain the uniformity in combustion of the tobacco (40, 42) and the ignition element (36).
