Abstract

There is provided a smoking article (10) comprising: a tobacco rod (12) comprising a charge (16) of tobacco material circumscribed by a wrapper (18); a filter (14) arranged downstream of the tobacco rod (12); and a hollow tube (20) defining an inner cavity (22) and attaching the filter (14) to the tobacco rod (12). An affixing portion (24) of the tobacco rod (12) is received within the inner cavity (22) and secured to the hollow tube (20) by means of a thermally deactivatable adhesive (26) provided on an outer surface of the wrapper (18) or on an inner surface of the hollow tube (20) or on both. Thus, upon deactivation of the adhesive, at least a portion of the tobacco rod (12) becomes slidable within the hollow tube (20) in relation to the filter (14).

As the rod of smokeable material is sucked, the coal is advanced towards the mouth end of the rod. [0003] Consumers typically extinguish their cigarettes just as the burnt coal is about to reach the filter. This usually requires the use of an ashtray or other suitable surface against which to extinguish the cigarette. This can undesirably leave an unpleasant odor on the consum...
