Tubular cigarette device comprising cerium oxide |
摘要 |
A device for minimizing cigarette sidestream smoke and reducing free-burn rate of a burning cigarette is disclosed. The device comprises a non-combustible tubular element encasing an effective length of a tobacco charge of a cigarette located in the tubular element. The tubular element minimizes sidestream smoke emission from a burning tobacco charge and reduces free-burn rate of such burning tobacco charge to increase the number of puffs from the burning tobacco charge.
