Abstract

The invention relates to a reconstituted smoking material which comprises a non-polyol aerosol generator, tobacco (optional), binder (optional) and inorganic filler. A further polyol aerosol generator may also be contained in the smoking material. There is also provided a smoking article containing such material in a conventional arrangement or with a core axially disposed within an annulus. A further aspect of the invention is the provision of a polyol or non-polyol aerosol generator disposed in the filter element of a smoking article, which may contain the inventive smoking material. The aerosol material on the filter is eluted into the aerosol of the smoke on burning of the smoking article.

Claims (8)

1. A smoking article comprising a smokable rod and a filter, said rod comprising a core and an outer part, said core comprising a first smoking material and a first cigarette paper wrapper enwrapping said first smoking material and said outer part comprising a second smoking material disposed annularly about said core and a second cigarette paper wrapper enwrapping said second smoking material, wherein either of said first or said second smoking material comprises from 6 to 30% by weight of a non-polyol aerosol generator, selected from the group consisting of triethylene glycol diacetate, glycerol triacetate, glycerol diacetate or a combination thereof, up to 20% by weight tobacco, binder at not more than 20% by weight and not less than 30% by weight inorganic filler of CaCO 3 .

2. A smoking article according to claim 1 , wherein said smoking material of either of said first or second smoking material is particulate.

3. A smoking article according to claim 1 , wherein both said first and said second smoking materials comprise from 6 to 30% by weight of said non-polyol aerosol generator, up to 20% by weight tobacco, binder at not more than 20% by weight and not less than 30% by weight inorganic filler of CaCO 3 .

4. A smoking article according to claim 1 , wherein the other of said first or second smoking material is cut tobacco filler.

5. A smoking article according to claim 1 , wherein both said core and said outer part of said smokable rod extend over the full length of said rod.

6. A smoking article according claim 1 wherein said core is disposed coaxially of said rod.

7. A smoking article according to claim 1 and the filter comprising filtration material containing an elutable aerosol generator which is a polyol and/or a non-polyol aerosol generator, said elutable aerosol generator being elutable from the filter upon smoking of the smoking article to enhance the aerosol provided from the smoking material.

8. A smoking article comprising a smokable rod and a filter, said rod comprising a core and an outer part, said core comprising a first smoking material and said outer part comprising a second smoking material disposed annularly about said core, wherein either of said first or said second smoking material comprises from 6 to 30% by weight of a non-polyol aerosol generator, up to 20% by weight tobacco, binder at not more than 20% by weight and not less than 30% by weight chalk.
