This invention provides a smoking article (1) having reduced sidestream smoke in the inter-puff period. A smoking article (1) according to the invention may comprise segments of a high level of tobacco-containing material (5) interconnected by segments of low level of tobacco-containing material (6) which are capable of maintaining smoulder in the inter-puff period and re-igniting the segments of a high level of tobacco-containing material (5) in the puff period. Alternatively, a smoking article according to another aspect of the invention may comprise a lengthwise, axially extending, tobacco-containing fuse portion (46) which sustains smoulder in the inter-puff period when surrounding tobacco material (45) is substantially extinguished and which re-ignites the extinguished material on puffing of the smoking article (1).
A smoking article comprising a rod of combustible material wrapped in a wrapper, which rod is provided with an inter-puff region capable of maintaining smoulder in an inter-puff period of time between puffs whilst adjacent material is extinguished, the inter-puff region comprising a fuse portion which extends substantially along the full length of said rod of combustible material and said fuse portion comprising tobacco-containing material comprised of tobacco material and one or more non-tobacco materials selected from the group consisting of binders;
A smoking article comprising a rod of combustible material wrapped in a wrapper, which rod is provided with an inter-puff region capable of maintaining smoulder in an inter-puff period of time between puffs whilst adjacent material is extinguished, said rod of combustible material comprising a coiled arrangement of a thread of tobacco-containing material, said inter-puff region extending lengthwise but not linearly coaxially of said rod, and said material of said inter-puff region being the same as the material of said puff region, said inter-puff region comprising tobacco-containing material comprised of tobacco material and one or more non-tobacco materials selected from the group consisting of binders;
