Beschreibung
Zusammenfassung:	A smoking article includes a cylinder of smoking material, a filter attached to the cylinder of smoking material, and a tube of preferably porous and/or perforated material adapted to collapse at an open end upon exposure to thermal energy and preferably extending from one end portion of the smoking material to the junction of the filter and the cylinder of smoking material. Thermal energy generated by a burning portion of the tobacco filler material within the cylinder of smoking material is transferred by convection through the open portion of the tube after the end portion of the tube has collapsed closed by the heat from the burning portion of the tobacco.
