Abstract

An aerosol-generating article for an aerosol-generating device including a heating element is provided, the aerosol-generating article including: an aerosol-forming substrate including homogenised tobacco material; a support element disposed immediately downstream of the aerosol-forming substrate; an aerosol-cooling element disposed downstream of the support element; and an outer wrapper circumscribing the aerosol-forming substrate, the support element, and the aerosol-cooling element, the support element abutting the aerosol-forming substrate.

Claims (53)

1. An aerosol-generating article for an aerosol-generating device comprising a heating element, the aerosol-generating article comprising:

an aerosol-forming substrate comprising homogenised tobacco material;

a support element disposed immediately downstream of the aerosol-forming substrate;

an aerosol-cooling element disposed downstream of the support element; and

an outer wrapper circumscribing the aerosol-forming substrate, the support element, and the aerosol-cooling element,

wherein the support element abuts the aerosol-forming substrate.

2. The aerosol-generating article according to claim 1 , wherein the aerosol-forming substrate is penetrable by the heating element of the aerosol-generating device.

3. The aerosol-generating article according to claim 1 ,

further comprising a front plug upstream of the aerosol-forming substrate,

wherein the front plug is penetrable by the heating element of the aerosol-generating device, and

wherein the outer wrapper circumscribes the aerosol-forming substrate, the support element, the aerosol-cooling element, and the front plug.

4. The aerosol-generating article according to claim 1 , wherein the support element is configured to resist a penetration force of at least 2.5 Newtons during insertion of the heating element of the aerosol-generating device into the aerosol-forming substrate.

5. The aerosol-generating article according to claim 1 , wherein the aerosol-forming substrate is disposed at an extreme upstream end of the aerosol-generating article.

6. The aerosol-generating article according to claim 1 , wherein the aerosol-forming substrate comprises a gathered sheet of the homogenised tobacco material.

7. The aerosol-generating article according to claim 6 , wherein the gathered sheet of homogenised tobacco material is crimped.

8. The aerosol-generating article according to claim 1 , wherein the support element comprises a hollow tubular element.

9. The aerosol-generating article according to claim 8 , wherein the support element further comprises a hollow cellulose acetate tube.

10. The aerosol-generating article according to claim 1 , wherein the aerosol-cooling element is disposed immediately downstream of the support element and abuts the support element.

11. The aerosol-generating article according to claim 1 , wherein the aerosol-cooling element comprises a gathered sheet of biodegradable polymeric material.

12. The aerosol-generating article according to claim 11 , wherein the aerosol-cooling element further comprises a gathered sheet of polylactic acid.

13. The aerosol-generating article according to claim 1 ,

further comprising a mouthpiece disposed at an extreme downstream end of the aerosol-generating article,

wherein the outer wrapper circumscribes the mouthpiece.

14. The aerosol-generating article according to claim 13 , wherein the mouthpiece comprises a plug of cellulose acetate tow.

15. An aerosol-generating system, comprising:

an aerosol-generating device comprising a heating element; and

an aerosol-generating article according to claim 1 .

16. An aerosol-generating article for an aerosol-generating device comprising a heating element, the aerosol-generating article comprising:

an aerosol-forming substrate comprising between 5% and 30% by weight of an aerosol former, on a dry weight basis;

a support element disposed immediately downstream of the aerosol-forming substrate;

an aerosol-cooling element disposed downstream of the support element; and

an outer wrapper circumscribing the aerosol-forming substrate, the support element, and the aerosol-cooling element,

wherein the support element abuts the aerosol-forming substrate.

17. The aerosol-generating article according to claim 16 , wherein the aerosol-forming substrate is penetrable by the heating element of the aerosol-generating device.

18. The aerosol-generating article according to claim 16 ,

further comprising a front plug upstream of the aerosol-forming substrate,

wherein the front plug is penetrable by the heating element of the aerosol-generating device, and

wherein the outer wrapper circumscribes the aerosol-forming substrate, the support element, the aerosol-cooling element, and the front plug.

19. The aerosol-generating article according to claim 16 , wherein the support element is configured to resist a penetration force of at least 2.5 Newtons during insertion of the heating element of the aerosol-generating device into the aerosol-forming substrate.

20. The aerosol-generating article according to claim 16 , wherein the aerosol-forming substrate is disposed at an extreme upstream end of the aerosol-generating article.

21. An aerosol-generating article for an aerosol-generating device comprising a heating element, the aerosol-generating article comprising:

an aerosol-forming substrate having a length of between 7 millimetres and 15 millimetres;

a support element disposed immediately downstream of the aerosol-forming substrate;

an aerosol-cooling element disposed downstream of the support element; and

an outer wrapper circumscribing the aerosol-forming substrate, the support element, and the aerosol-cooling element,

wherein the support element abuts the aerosol-forming substrate.

22. The aerosol-generating article according to claim 21 , wherein the aerosol-forming substrate is disposed at an extreme upstream end of the aerosol-generating article.

23. An aerosol-generating article for an aerosol-generating device comprising a heating element, the aerosol-generating article comprising:

an aerosol-forming substrate;

a support element disposed immediately downstream of the aerosol-forming substrate;

an aerosol-cooling element disposed downstream of the support element, wherein the aerosol-cooling element comprises a gathered sheet of biodegradable polymeric material; and

an outer wrapper circumscribing the aerosol-forming substrate, the support element, and the aerosol-cooling element,

wherein the support element abuts the aerosol-forming substrate.
