Abstract
A smoking article includes a cylinder of smoking material having at least one hollow tube having a heat conductive wall within the cylinder of smoking material and a filter system attached to the cylinder of smoking material. The filter system includes an adsorbent material therein. The at least one hollow tube extends from within the cylinder of smoking material through the adsorbent material. At least one flavorant material is retained within the at least one hollow tube, and upon exposure to heat from the heat conductive wall of the hollow tube the flavorant material releases a flavorant.
Claims15
A smoking article comprising:
- a cylinder of smoking material;
- a filter system attached to the cylinder of smoking material, the filter system having an adsorbent material;
- at least one hollow tube having a heat conductive wall within the cylinder of smoking material, the at least one hollow tube extending from within the cylinder of smoking material through the adsorbent material;
- and
- at least one flavorant material retained within the at least one hollow tube, and wherein the flavorant material releases a flavorant upon exposure to heat from the heat conductive wall of the hollow tube.
A smoking article comprising:
- a cylinder of smoking material;
- at least one hollow tube within the cylinder of smoking material, the at least one hollow tube having a heat conductive wall;
- and
- a filter system attached to the cylinder of smoking material, the filter system having an adsorbent material located between upstream and downstream filtering material and wherein the at least one hollow tube extends from within the cylinder of smoking material through the upstream filtering material and adsorbent material into the downstream filtering material.
