摘要： A smoking article comprises a tobacco rod and a filter connected to the tobacco rod. The filter comprises a first filter segment and a hollow tube segment downstream of the first filter segment. The hollow tube segment defines a cavity at the mouth end of the filter providing an unrestricted flow channel that extends from the downstream end of the first filter segment to the mouth end of the filter. The length of the hollow tube segment is at least about 25 percent of the overall filter length. Further, the smoking article comprises a ventilation zone comprising at least one circumferential row of perforations provided at a location around the first filter segment.

摘要： A smoking article assembly (100) comprising a smoking article (80), and a tube (10) for temporary affixment to the smoking article. The smoking article comprises a tobacco rod, and a mouthpiece comprising a filter and a tipping wrapper, the tipping wrapper circumscribing the filter and attaching the filter to the tobacco rod. The tube is configured to be disposed around at least a portion of the mouthpiece such that the tube is slidable over the outer surface of the tipping wrapper. The tube comprises an open upstream end; an open downstream end; an outer surface; and an inner surface defining a lumen for receiving the mouthpiece of the smoking article, the lumen extending from the open upstream end to the open downstream end. The coefficient of static friction between the inner surface of the tube and the outer surface of the tipping wrapper may be between about 0.5 and about 0.9. The lumen may be substantially cylindrical and have a diameter that is between one percent and four percent greater than the average diameter of the smoking article mouthpiece.
