Abstract (en)
A smoking article (10)(50) comprises: a rod (2) of smokable material; a filter (4) circumscribed by a filter wrapper (56)(16,18); a rod end band (20) of tipping paper attaching the rod (2) to the filter (4); a mouth end band (22) of tipping paper; and a substantially air impermeable sleeve (24) disposed between the rod end (20) and mouth end (22) bands of tipping paper. The sleeve (24) overlies a portion of the filter wrapper and is moveable relative thereto between a first position and a second position, wherein the level of ventilation obtained in the first position is different to the level of ventilation obtained in the second position. Preferably, the sleeve (24) is a central band of tipping paper.
