Abstract

The aerosol-generating article comprises a housing having an open end. The housing comprises a cavity for holding an aerosol-forming substrate. The article further comprises a piston movable within the housing into the direction of the open end of the housing. The aerosol-generating device comprises a cavity for receiving at least a portion of an aerosol-generating article comprising an aerosol-forming substrate. A heating chamber is arranged adjacent the cavity for heating aerosol-forming substrate received from the aerosol-generating article. The cavity and the heating chamber are arranged along a same longitudinal axis such that aerosol-forming substrate is transferrable from the aerosol-generating article into the heating chamber with a linear movement in the direction of the longitudinal axis.

First claim

The invention claimed is:

1. Aerosol-generating article for use with an aerosol-generating device, comprising an article-receiving cavity configured to receive at least a portion of the aerosol-generating article and a heating chamber arranged adjacent the article-receiving cavity for heating aerosol-forming substrate received from the aerosol-generating article, the article comprising a housing having an open end, the housing comprising a substrate-holding cavity for holding an aerosol-forming substrate, wherein a solid aerosol-forming substrate is provided in the substrate-holding cavity, the article further comprising a piston movable within the housing into the direction of the open end of the housing.

2. Aerosol-generating article according to claim 1 , wherein a length of the housing is identical to or longer than a length of the piston.

3. Aerosol-generating article according to claim 1 , further comprising at least one airflow channel through the article, the airflow channel extending from one end of the article to an opposite end of the article.

4. Aerosol-generating article according to claim 3 , wherein the at least one airflow channel is arranged along the piston.

5. Aerosol-generating system comprising an aerosol-generating device and an aerosol-generating article according to claim 4 , wherein the article-receiving cavity and the heating chamber are arranged along a same longitudinal axis such that aerosol-forming substrate is transferrable from the aerosol-generating article into the heating chamber with a linear movement in the direction of the longitudinal axis,
wherein the aerosol-generating article is arranged at least partially in the article-receiving cavity of the device.

6. Aerosol-generating system comprising an aerosol-generating device and an aerosol-generating article according to claim 3 , wherein the article-receiving cavity and the heating chamber are arranged along a same longitudinal axis such that aerosol-forming substrate is transferrable from the aerosol-generating article into the heating chamber with a linear movement in the direction of the longitudinal axis,
wherein the aerosol-generating article is arranged at least partially in the article-receiving cavity of the device.

7. Aerosol-generating system according to claim 6 , wherein the device comprises a push element adapted for pushing the piston of the aerosol-generating article relative to the housing of the aerosol-generating article.

8. Aerosol-generating system according to claim 6 , wherein the device comprises a device housing and a mouthpiece, the mouthpiece comprising the push element.

9. Aerosol-generating system comprising an aerosol-generating device, and an aerosol-generating article according to claim 1 wherein the article-receiving cavity and the heating chamber are arranged along a same longitudinal axis such that aerosol-forming substrate is transferrable from the aerosol-generating article into the heating chamber with a linear movement in the direction of the longitudinal axis,
wherein the aerosol-generating article is arranged at least partially in the article-receiving cavity of the device.

10. Aerosol-generating system according to claim 9 , wherein the device further comprises an ejection mechanism for ejecting aerosol-forming substrate out of the heating chamber.

11. Aerosol-generating system according to claim 10 , wherein the device comprises a push element adapted for pushing the piston of the aerosol-generating article relative to the housing of the aerosol-generating article.

12. Aerosol-generating system according to claim 9 , wherein the device comprises a push element adapted for pushing the piston of the aerosol-generating article relative to the housing of the aerosol-generating article.

13. Aerosol-generating system according to claim 12 , wherein the device comprises a device housing and a mouthpiece, the mouthpiece comprising the push element.

14. Aerosol-generating system according to claim 9 , wherein the heating chamber comprises a base and heating chamber walls, which base is relatively movable to heating chamber walls.

15. Aerosol-generating system according to claim 9 , wherein an inner lateral dimension of the housing of the aerosol-generating article corresponds to an inner lateral dimension of the heating chamber.

16. Kit for an aerosol-generating system, the kit comprising an aerosol-generating device and an aerosol-generating article comprising an aerosol-forming substrate,
the aerosol-generating device comprising an article-receiving cavity configured to receive at least a portion of the aerosol-generating article comprising an aerosol-forming substrate, the device further comprising a heating chamber arranged adjacent the article-receiving cavity for heating aerosol-forming substrate received from the aerosol-generating article,
the aerosol-generating article comprising a housing having an open end, the housing comprising a substrate-holding cavity for holding aerosol-forming substrate, wherein a solid aerosol-forming substrate is provided in the substrate-holding cavity, the article further comprising a piston movable within the housing into the direction of the open end of the housing;
wherein the aerosol-generating article is configured to be mounted at least partly in the article-receiving cavity of the aerosol-generating device such that the aerosol-forming substrate is transferrable from the aerosol-generating article into the heating chamber with a linear movement.

17. Kit according to claim 16 , wherein the device further comprises an ejection mechanism for ejecting aerosol-forming substrate out of the heating chamber.

18. Kit according to claim 16 , wherein the heating chamber comprises a movable base, which is configured to be movable into the direction of the top of the heating chamber such that used aerosol-forming substrate is ejectable out of the heating chamber.

19. Kit according to claim 16 , wherein the device comprises a push element adapted for pushing the piston of the aerosol-generating article relative to the housing of the aerosol-generating article.

20. Kit according to claim 19 , wherein the device comprises a device housing and a mouthpiece, the mouthpiece comprising the push element.
