Abstract

A shisha consumable cartridge includes a housing having an exterior surface sized and shaped for operable insertion into a shisha device. The cartridge further includes a first chamber in the housing; a first aerosol-generating substrate in the first chamber; a second chamber in the housing and adjacent to the first chamber. A second aerosol-generating substrate in the second chamber. The compositions of the first aerosol-generating substrate and the second aerosol-generating substrate may be the same or different. The first chamber defines a first fresh air inlet and an opposing first aerosol outlet, such that, in use, fresh air entering the first fresh air inlet carries aerosol generated from through the first aerosol outlet. The second chamber defines a second fresh air inlet and an opposing second aerosol outlet, such that, in use, fresh air entering the second fresh air inlet carries aerosol generated from through the second aerosol outlet.

First claim

The invention claimed is:

1. A shisha consumable cartridge comprising:
a housing having an exterior surface sized and shaped for operable insertion into a shisha device;
a first chamber in the housing;
a first aerosol-generating substrate in the first chamber;
a second chamber in the housing, wherein the second chamber is adjacent to the first chamber;
a second aerosol-generating substrate in the second chamber, wherein the compositions of the first aerosol-generating substrate and the second aerosol-generating substrate are the same or different;
wherein the first chamber defines a first fresh air inlet and an opposing first aerosol outlet, such that, in use, fresh air entering the first fresh air inlet carries aerosol generated from through the first aerosol outlet;
wherein the second chamber defines a second fresh air inlet and an opposing second aerosol outlet, such that, in use, fresh air entering the second fresh air inlet carries aerosol generated from through the second aerosol outlet; and
wherein the first and second chambers, each independently, have an aspect ratio of at least 1.5:1, or at least 2:1, or at least 3:1.

2. The shisha consumable cartridge according to claim 1 , further comprising one or more additional chambers in addition to the first and second chambers.

3. The shisha consumable cartridge according to claim 2 , wherein at least one of the chambers is empty.

4. The shisha consumable cartridge according to claim 1 , wherein the chambers are formed from thermally conductive material.

5. The shisha consumable cartridge according to claim 4 , wherein the thermally conductive material comprises aluminium.

6. The shisha consumable cartridge according to claim 1 , wherein the cartridge is formed from a magnetic induction susceptor material.

7. The shisha consumable cartridge according to claim 6 , wherein the first and second chambers are cylindrical chambers.

8. The shisha consumable cartridge according claim 1 , wherein the first and second chambers have polygonal cross-sectional shapes along a majority of their lengths.

9. The shisha consumable cartridge according to claim 8 , wherein the cross-sectional shapes are hexagonal.

10. The shisha consumable cartridge according to claim 9 , wherein at least one sidewall of the first chamber is a sidewall of the second chamber.

11. The shisha consumable cartridge according to claim 10 , wherein the first and second chambers are part of a honeycomb array of chambers.

12. The shisha consumable cartridge according to claim 11 , wherein the array of chambers comprises at least 7 chambers.

13. A shisha assembly comprising:
a vessel defining an interior configured to contain a volume of liquid, the vessel comprising a head space outlet conduit;
an aerosol-generating element in fluid connection with the vessel, the aerosol-generating element comprising:
a cartridge receptacle configured to receive a shisha consumable cartridge, according to claim 1 ;
a heating element in thermal contact with the shisha consumable cartridge, wherein the heating element is configured (i) to heat different chambers of the cartridge at different temperatures, (ii) to heat different chambers of the cartridge at different times, (iii) to heat one or more chambers of the cartridge using varying temperature profiles, or any combination of one or more of (i)-(iii); and

an aerosol outlet in fluid connection with the cartridge receptacle and a fresh air inlet channel in fluid connection with the cartridge receptacle.

14. A shisha assembly comprising:
a vessel defining an interior configured to contain a volume of liquid, the vessel comprising a head space outlet conduit;
an aerosol-generating element in fluid connection with the vessel, the aerosol-generating element comprising:
a cartridge receptacle configured to receive a shisha consumable cartridge, according to claim 1 , wherein a material forming the first and second chambers comprises a magnetic susceptor material;
an inductive heating element configured to heat the susceptor material when the cartridge is received in the receptacle, wherein the heating element is configured (i) to heat different chambers of the cartridge at different temperatures, (ii) to heat different chambers of the cartridge at different times, (iii) to heat one or more chambers of the cartridge using varying temperature profiles, or any combination of one or more of (i)-(iii); and

an aerosol outlet in fluid connection with the cartridge receptacle and a fresh air inlet channel in fluid connection with the cartridge receptacle.

15. The shisha assembly according to claim 13 , wherein the shisha device is configured to control heating of the heating element such that the aerosol-generating substrate in the shisha consumable cartridge is sufficiently heated to generate an aerosol but not to cause the aerosol-generating substrate to burn during operation.

16. The shisha consumable cartridge according to claim 1 , wherein at least one of the first aerosol-generating substrate and the second aerosol-generating substrate comprises tobacco.
