Abstract

The invention provides an article, such as an aerosol-generating smoking article that does not combust tobacco, that includes a tobacco rod and a filter element connected to the tobacco rod, the filter element having an end proximal to the tobacco rod and an end distal from the tobacco rod, wherein the filter element includes a first section of filter material and a second section of filter material, and further includes a smoke-altering flavorant.

First claim

What is claimed is:

1. An article comprising a tobacco rod and a filter element connected to the tobacco rod, said filter element having an end proximal to the tobacco rod and an end distal from the tobacco rod defining a mouth end of the article, wherein said filter element comprises a first section of filter material with a plurality of channels formed therein and extending at least partially longitudinally through the first section of filter material, said plurality of channels each being adapted for passage of mainstream smoke between said tobacco rod and a second section of filter material arranged in an end-to-end configuration with said first section of filter material, the first section of filter material comprising a gathered polyester web and a smoke-altering material comprising a flavorant and the second section of filter material comprising cellulose acetate, wherein a filter material comprising cellulose acetate is positioned in at least one of said plurality of channels of said first section of filter material.

2. The article of claim 1 , wherein the total cross-sectional area of said plurality of channels is about 0.1 mm 2 to about 50 mm 2 .

3. The article of claim 1 , wherein each of said plurality of channels has an internal diameter of about 0.25 mm to about 2 mm.

4. The article of claim 1 , wherein the tobacco rod comprises an aerosol forming material.

5. The article of claim 4 , wherein the aerosol forming material comprises a polyol.

6. The article of claim 4 , wherein the aerosol forming material is present in an amount of about 10 weight percent to about 50 weight percent, based on the combined dry weight of the aerosol forming material and tobacco material.

7. The article of claim 4 , wherein the tobacco rod comprises reconstituted tobacco.

8. The article of claim 7 , wherein the reconstituted tobacco is manufactured using paper-making type or cast sheet type processes.

9. The article of claim 1 , wherein the flavorant is menthol.

10. The article of claim 1 , wherein the article is an aerosol-generating smoking article that does not combust tobacco.

11. The article of claim 1 , wherein the plurality of channels in the first section of filter material include a plurality of channels positioned along the periphery of the first section of filter material.
