摘要 |
A smoking article (10) incorporates a tobacco rob (12) and a filter attached to the tobacco rod. The filter includes a concentric filter segment (20) having a central core portion (23) with sorbent material and an outer periphery layer (24) circumscribed about the central core portion. At least about 80 weight % of the sorbent in the smoking article is disposed in the central core portion. The central core portion has a lower RTD than the periphery layer. A ventilation zone (30) is disposed adjacent an upstream end of the concentric sorbent segment. |
