Flavoured rods for use in aerosol-generating articles
A rod is provided, formed from a first sheet including a tobacco material and a second sheet including a non-tobacco flavourant, the first and second sheets being gathered together and circumscribed by a wrapper. The rod may be used as a component part of an aerosol-generating article.
1. A rod, comprising:
a first sheet comprising tobacco material, wherein the first sheet is crimped; and
a second sheet comprising a non-tobacco flavourant, wherein the second sheet is crimped,
wherein the first sheet and the second sheet are of the same width, and
wherein the first sheet and the second sheet in an overlapping relationship are gathered together and circumscribed by a wrapper, such that the non-tobacco flavourant and the tobacco material are evenly distributed throughout the rod, a cross-section taken at any point along a length of the rod having the same proportion of the first sheet to the second sheet.
2. The rod according to claim 1 , wherein the first sheet is a sheet of homogenised tobacco material.
3. The rod according to claim 1 , wherein the second sheet is a polymeric or a paper sheet coated with the non-tobacco flavourant.
4. The rod according to claim 1 , wherein the second sheet is a polymeric or paper sheet impregnated with the non-tobacco flavourant.
5. The rod according to claim 1 , wherein the second sheet comprises a biodegradable polymer.
6. The rod according to claim 1 , wherein the non-tobacco flavourant comprises menthol.
7. The rod according to claim 1 , wherein the second sheet comprises polylactic acid.
8. The rod according to claim 1 , wherein the rod has a substantially uniform cross-section.
9. A smoking article comprising a rod according to claim 1 .
10. An aerosol-forming substrate for a heated aerosol-generating article comprising a rod according to claim 1 .
11. A system comprising an electrically-operated aerosol-generating apparatus and an aerosol-generating article for use with the apparatus, the aerosol-generating article comprising an aerosol-forming substrate according to claim 10 .
12. A heated aerosol-generating article comprising a combustible heat source and an aerosol-forming substrate according to claim 10 located downstream of the combustible heat source.
13. A heated aerosol-generating article for use in an electrically-operated aerosol-generating system comprising an aerosol-forming substrate according to claim 10 .
