CIGARETTE SYSTEM

摘要

28 A novel non-self-extinguishing factory-made cigarette is described which has a free burn rate of no more than about 4 mm/min., preferably no more than about 3.5 mm/min. This free burn rate permits the provision of a cigarette having a greater number of puffs, at least about 2 more, preferably at least about 4 more and more preferably at least about 6 more, than a conventional cigarette of same dimensions and length of tobacco rod. The cigarettes may be partially smoked, extinguished, stored and then resmoked. The free burn rate and greater-than-normal number of puffs may be achieved by employing a slower burning tobacco blend, a lower draw resistance tobacco, a greater tobacco density and/or a burn rate retardant wrapper.
