CIGARETTE HAVING REDUCED SIDESTREAM SMOKE

摘要

A cigarette (30) includes an ignition element (36) in contact with tobacco (40, 42), surrounded by a composite outer wrapper (38). The outer wrapper (3 8) is impervious to oxygen causing the tobacco (40, 42) to extinguish between puffs. The ignition element (36), however, has a longer static burn time tha n the tobacco (40, 42) and remains smoldering between puffs. Upon a subsequent puff, the smoldering ignition element (36) reignites the tobacco (40, 42). O ne or more initially occluded perforations (34) in the outer layer (38) maintai n the uniformity in combustion of the tobacco (40, 42) and the ignition elemen t (36).
