CIGARETTE SIDESTREAM SMOKE AND FREE-BURN RATE CONTROL DEVICE

摘要

PURPOSE: A cigarette sidestream smoke and free-burn rate control device is provided, which is to be used in combination with a cigarette or other tobacco product to control sidestream smoke and increase the number of puffs available to the smoker from a given amount of tobacco. CONSTITUTION: A device for minimizing cigarette sidestream smoke and reducing free-burn rate of a burning cigarette comprises: i) a non-combustible tubular element (12) encasing an effective length of a tobacco charge of a cigarette (14) located in the tubular element; and ii) the tubular element having a means for both minimizing sidestream smoke emission from a burning tobacco charge and reducing free-burn rate of such burning tobacco charge to increase number of puffs from the burning tobacco charge.
