Abstract

Claims (26)

1 . A cartridge for an aerosol provision system, wherein the cartridge comprises:

a reservoir containing aerosolizable material for aerosolizing;

an aerosolizable-material-level observation means for allowing a user to observe a level of aerosolizable material inside the reservoir;

wherein the aerosolizable-material-level observation means comprises a portion of the reservoir, and wherein an optical property of the portion of the reservoir is varied in operation by the user of the cartridge;

wherein the aerosolizable-material-level observation means further comprises a light source for illuminating the contents of the reservoir.

2 . A cartridge according to claim 1 , wherein the aerosolizable-material-level observation means is material from the reservoir which can vary between a first state and a second state, wherein visibility through the reservoir is greater in the second state than when the material is in the first state.

3 . A cartridge according to claim 1 , wherein the light source is attached to a wall of the reservoir.

4 . A cartridge according to claim 1 , further comprising an air channel extending from an air inlet for the cartridge to an outlet via an aerosol generation region.

5 . A cartridge according to claim 4 , further comprising an aerosol outlet tube, extending between the aerosol generating region and the outlet, for directing aerosol generated in the aerosol generating region through to the outlet.

6 . A cartridge according to claim 5 , wherein the reservoir extends around the aerosol outlet tube.

7 . A cartridge according to claim 1 , wherein the reservoir is annular.

8 . A cartridge according to claim 1 , further comprising a vaporiser located in the cartridge.

9 . A cartridge according to claim 8 , when further dependent on claim 4 wherein the reservoir comprises a first end which is proximal the outlet of the cartridge, and a second end which is proximal the vaporiser.

10 . An aerosol provision system comprising the cartridge of claim 1 and a control unit, wherein the control unit comprises a receptacle that includes an interface arranged to cooperatively engage with the cartridge so as to releasably couple the cartridge to the control unit, wherein the control unit further comprises a power supply and control circuitry.

11 . A method of observing the level of aerosolizable material inside a reservoir from the cartridge according to claim 1 , wherein the method comprises:

illuminating the contents of the reservoir using the light source; and

using the aerosolizable-material-level observation means to observe the level of aerosolizable material inside the reservoir.

12 . A method of observing the level of aerosolizable material inside a reservoir from the aerosol provision system according to claim 10 , wherein the method comprises:

illuminating the contents of the reservoir using the light source; and

using the aerosolizable-material-level observation means to observe the level of aerosolizable material inside the reservoir.

13 . An aerosol provision system, wherein the system comprises:

a reservoir containing aerosolizable material for aerosolizing;

an aerosolizable-material-level observation means for allowing a user to observe a level of aerosolizable material inside the reservoir;

wherein the aerosolizable-material-level observation means comprises a portion of the reservoir, and wherein an optical property of the portion of the reservoir is varied in operation by the user of the aerosol provision system;

wherein the aerosolizable-material-level observation means further comprises a light source for illuminating the contents of the reservoir; and

wherein the light source is located in the reservoir and/or is attached to a wall of the reservoir.
