Abstract

A cartridge for housing an aerosol-forming substrate includes a body with 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, where the cap is movable between a first position, in which the wall opening is open, and a second position, in which the wall opening is closed by the cap.

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,
wherein the cap is movable between a first position, in which the wall opening is open, and a second position, in which the wall opening is closed by the cap, wherein the cartridge is constructed for use in a shisha device when heated, and the body is made of one or more heat resistant materials, wherein the cap comprises a cap opening, and wherein the cap is rotatable about an axis from the first position to the second position, 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.

2. 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.

3. The cartridge according to claim 1 , wherein the wall opening comprises a single hole.

4. The cartridge according to claim 1 , wherein the wall opening comprises a plurality of holes.

5. The cartridge according to claim 1 , wherein the wall opening comprises 5% or greater of an area of the wall the opening is on, or 75% or less of the area of the wall the opening is on, or both.

6. The cartridge according to claim 1 , the cap comprising a cap opening having a shape of a sector of a circle.

7. The cartridge according to claim 1 , the cap comprising a cap opening comprising a plurality of holes.

8. The cartridge according to claim 1 , the cap comprising a cap opening comprising 5% or greater of an area of the cap, or 75% or less of an area of the cap, or both.

9. The cartridge according to claim 1 , wherein the cap is removably attached to the body.

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

11. The cartridge according to claim 10 , wherein the aerosol-forming substrate comprises tobacco.

12. The cartridge according to claim 10 , wherein the aerosol-forming substrate comprises a shisha aerosol-forming substrate.

13. The cartridge according to claim 1 , wherein the body comprises an interior wall dividing the cavity into at least a first section and a second section, and wherein the cap is rotatable to selectively open the first section or the second section or to close both the first and second sections.

14. The cartridge according to claim 13 , wherein the cap comprises a planar portion with a central opening and a tubular portion aligned with the central opening and extending from the planar portion into the body of the cartridge with a center axis disposed perpendicular to the planar portion of the cap, the cap opening comprising an opening in the tubular portion of the cap, the tubular portion being constructed to selectively open one of the sections.

15. The cartridge according to claim 14 , wherein the body comprises an outer wall and inner cylindrical wall comprising the wall opening, the tubular portion of the cap being disposed adjacent the inner cylindrical wall of the body.

16. A shisha system comprising:
the cartridge of 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 cartridge of claim 5 , wherein the wall opening comprises 75% or less of the area of the wall the opening is on.
