Abstract

Smoking articles are disclosed herein. The present disclosure is directed to a smoking article that comprises a heat source configured to generate heat upon ignition thereof, a substrate material having opposed first and second ends, the heat source being disposed proximate the first end of the substrate material and the substrate material having an aerosol precursor composition associated therewith, a mouthpiece, the mouthpiece being disposed proximate the second end of the substrate material, and a heat transfer component. In one implementation, the heat transfer component comprises a hollow structure and opposing first and second flanges located on respective ends thereof, wherein the hollow structure extends through the heat source such that the heat source is located between the first and second opposing flanges. In another implementation, the heat transfer component is located within the heat source, penetrates at least a portion of the substrate material, and includes a cap located between the heat source and the substrate material.

First claim

The invention claimed is:

1. A smoking article comprising:
a heat source configured to generate heat upon ignition thereof;
a substrate material having opposed first and second ends, the heat source being disposed proximate the first end of the substrate material, and the substrate material having an aerosol precursor composition associated therewith;
a mouthpiece, the mouthpiece being disposed proximate the second end of the substrate material; and
a heat transfer component located within the heat source,
wherein the heat transfer component extends from the heat source and penetrates at least a portion of the substrate material, wherein the heat transfer component includes a cap located between the heat source and the substrate material, and wherein the cap comprises an end portion that covers an end of the heat source and a rim portion that extends peripherally around at least a portion of a length of the heat source.

2. The smoking article of claim 1 , wherein the heat transfer component comprises one or more substantially close-ended structures.

3. The smoking article of claim 2 , wherein the one or more close-ended structures are constructed of at least one of aluminum, and copper with an aluminum coating.

4. The smoking article of claim 1 , wherein the heat transfer component comprises one or more substantially solid rods.

5. The smoking article of claim 4 , wherein the one or more substantially solid rods are constructed of at least one of aluminum, and copper with an aluminum coating.

6. The smoking article of claim 1 , wherein the heat transfer component comprises one or more substantially solid sheets.

7. The smoking article of claim 6 , the one or more substantially solid sheets are constructed of at least one of aluminum, and copper with an aluminum coating.

8. The smoking article of claim 1 , wherein the substrate material comprises at least one of tobacco-containing beads, tobacco shreds, tobacco strips, pieces of a reconstituted tobacco material, or tobacco rods.

9. The smoking article of claim 1 , further comprising a liner configured to circumscribe the substrate material and at least a portion of the heat source.

10. The smoking article of claim 1 , wherein the mouthpiece comprises an intermediate component.

11. The smoking article of claim 1 , wherein the mouthpiece comprises a filter.

12. The smoking article of claim 1 , wherein the heat source comprises an extruded monolithic carbonaceous material.

13. The smoking article of claim 12 , wherein the extruded monolithic carbonaceous material defines one or more grooves extending longitudinally from a first end of the extruded monolithic carbonaceous material to an opposing second end of the extruded monolithic carbonaceous material.

14. The smoking article of claim 1 , wherein the substrate material comprises a series of overlapping layers of an initial substrate sheet.

15. A smoking article comprising:
a heat source configured to generate heat upon ignition thereof;
a substrate material having opposed first and second ends, the heat source being disposed proximate the first end of the substrate material, and the substrate material having an aerosol precursor composition associated therewith;
a mouthpiece, the mouthpiece being disposed proximate the second end of the substrate material; and
a heat transfer component located within the heat source,
wherein the heat transfer component extends from the heat source and penetrates at least a portion of the substrate material, wherein the heat transfer component includes a cap located between the heat source and the substrate material, and wherein the heat transfer component comprises an aluminum mesh.

16. The smoking article of claim 15 , wherein the heat transfer component further comprises an aluminum disc positioned at a location along a length of the aluminum mesh.

17. A smoking article comprising:
a heat source configured to generate heat upon ignition thereof;
a substrate material having opposed first and second ends, the heat source being disposed proximate the first end of the substrate material, and the substrate material having an aerosol precursor composition associated therewith;
a mouthpiece, the mouthpiece being disposed proximate the second end of the substrate material; and
a heat transfer component located within the heat source,
wherein the heat transfer component extends from the heat source and penetrates at least a portion of the substrate material, wherein the heat transfer component includes a cap located between the heat source and the substrate material, and
further comprising a second substrate material having opposed first and second ends, the second substrate material being disposed between the first substrate material and the mouthpiece.

18. The smoking article of claim 17 , wherein the second substrate material comprises at least one of tobacco-containing beads, tobacco shreds, tobacco strips, pieces of a reconstituted tobacco material, or tobacco rods.
