Abstract

A cartridge for housing an aerosol-forming substrate includes a body with one or more walls having a wall opening; a cavity in the body in fluid communication with the at least one wall opening; and a cap rotatably connected to the body, where the cap is movable between a first position, in which the wall opening is exposed, and a second position, in which the wall opening is closed by the cap. The cap includes electrical connection points to selectively heat a portion of the contents of the cartridge.

First claim

The invention claimed is:

1. A cartridge for housing an aerosol-forming substrate, the cartridge comprising:
a body comprising one or more walls, and a wall opening in at least one of the one or more walls;
a cavity in the body in fluid communication with the at least one wall opening; and
a cap rotatably connected to the body, the cap comprising:
an outer edge;
a non-electrically-conductive material;
a first electrical connection point disposed along the outer edge;
a second electrical connection point disposed along the outer edge; and
an electrically conductive material forming an electrically conductive path extending from the first electrical connection point to the second electrical connection point,

wherein the cap is movable between a first position, in which the wall opening is exposed, and a second position, in which the wall opening is closed by the cap.

2. The cartridge according to claim 1 , wherein the outer edge of the cap outside of the first and second electrical connection points and of the electrically conductive material forming an electrically conductive path is non-electrically-conductive.

3. The cartridge according to claim 1 , wherein at least one of the one or more walls of the body comprises a resistive material.

4. The cartridge according to claim 1 , wherein the cap is rotatable about an axis to selectively form an electrical circuit comprising the electrically conductive path and a heating element.

5. The cartridge according to claim 1 , wherein the body comprises an interior wall dividing the cavity into at least a first compartment and a second compartment.

6. The cartridge according to claim 5 , wherein the cap is rotatable about an axis to selectively open the first compartment or the second compartment or to close both the first and second compartments.

7. The cartridge according to claim 5 , wherein at least one of the one or more walls of the body comprises two or more sections of resistive material, each section of resistive material corresponding to one of the two or more compartments.

8. The cartridge according to claim 1 , wherein the first and second electrical connection points define a sector of the cap, the cap comprising a cap opening within the sector, wherein in the first position the cap opening is at least partially aligned with the wall opening, and wherein in the second position the cap opening is not aligned with the wall opening.

9. The cartridge according to claim 1 , wherein the first and second electrical connection points are radially set apart by 20° degrees or greater.

10. The cartridge according to claim 1 , wherein the cap comprises an opening comprising a cut-out extending from the first electrical connection point to the second electrical connection point.

11. The cartridge according to claim 1 , wherein the wall opening is on a top wall, a bottom wall, or a side wall, or any combination thereof.

12. The cartridge according to claim 1 comprising an aerosol-forming substrate disposed in the cavity.

13. The cartridge according to claim 12 , wherein the aerosol-forming substrate comprises tobacco.

14. The cartridge according to claim 12 , wherein the aerosol-forming substrate comprises a shisha aerosol-forming substrate.

15. The cartridge according to claim 1 , wherein the body comprises an interior wall dividing the cavity into a first compartment and a second compartment, the cartridge comprising a first type of aerosol-forming substrate disposed in the first compartment and a second type of aerosol-forming substrate disposed in the second compartment.

16. A shisha system comprising:
the cartridge according to claim 1 with an aerosol-forming substrate disposed in the cartridge; and
a shisha device comprising:
a receptacle for receiving the cartridge;
a heating element for heating the aerosol-forming substrate when the cartridge is received in the receptacle of the shisha device;
a vessel having a liquid fill level and defining a head space above the liquid fill level;
an aerosol conduit for conveying aerosol from the receptacle to the vessel; and
an outlet in communication with the head space.

17. The shisha system according to claim 16 , wherein the receptacle comprises electrical connection points constructed to be aligned with and to connect with the first and second electrical connection points of the cartridge.

18. The shisha system according to claim 17 , wherein the heating element comprises two or more sections of resistive material that are selectively heatable when the first and second electrical connection points of the cartridge are aligned and connected with the electrical connection points of the receptacle.

19. The cartridge according to claim 1 , wherein the first and second electrical connection points are radially set apart by up to 150°.
