Abstract

Disclosed is a consumable for use with apparatus for heating aerosolisable material to volatilise at least one component of the aerosolisable material. The consumable comprises an outer tube, an inner member inside the outer tube, and at least one support that supports the inner member relative to the outer tube so that at least one air gap exists between the inner member and the outer tube. At least one of the inner member, the outer tube and the support comprises aerosolisable material that is heatable to generate aerosol in the air gap. The consumable has at least one outlet for permitting the aerosol to pass out of consumable from the air gap.

First claim

The invention claimed is:

1. A consumable for use with apparatus for heating aerosolisable material to volatilise at least one component of the aerosolisable material, wherein the consumable comprises:
an outer tube, an inner member inside the outer tube, wherein the inner member comprises a hollow inner tube that defines a passageway configured to receive a heating element of an apparatus for heating aerosolisable material, and at least one support that supports the inner member relative to the outer tube so that at least one air gap exists between the inner member and the outer tube;
wherein at least one of the inner member, the outer tube and the support comprises aerosolisable material that is heatable to generate aerosol in the air gap; and
wherein the consumable has at least one outlet for permitting the aerosol to pass out of consumable from the air gap.

2. The consumable of claim 1 , wherein the at least one support comprises a plurality of supports that are circumferentially spaced from each other.

3. The consumable of claim 1 , wherein the at least one support is located between the inner member and the outer tube.

4. The consumable of claim 3 , wherein the at least one support comprises an annular non-circular support between the inner member and the outer tube.

5. The consumable of claim 3 , wherein the at least one support comprises a folded or corrugated element between the inner member and the outer tube.

6. The consumable of claim 1 , wherein at least one of the inner member and the outer tube comprises the aerosolisable material.

7. The consumable of claim 6 , wherein the at least one of the inner member and the outer tube comprises a carrier, and the aerosolisable material is affixed to the carrier.

8. The consumable of claim 1 , wherein the at least one support comprises a heating material that is heatable by penetration with a varying magnetic field to thereby heat the aerosolisable material.

9. A system for heating aerosolisable material to volatilise at least one component of the aerosolisable material, the system comprising:
the consumable of claim 1 ; and
apparatus for heating the aerosolisable material of the consumable to volatilise at least one component of the aerosolisable material, the apparatus comprising a heating zone for receiving the consumable, and a device for causing heating of the aerosolisable material when the consumable is in the heating zone.

10. The system of claim 9 , wherein the device comprises a magnetic field generator for generating a varying magnetic field for penetrating the heating zone when the consumable is in the heating zone.

11. The system of claim 9 , wherein the device of the apparatus comprises a heatable heating element in the heating zone; and wherein the inner member of the consumable comprises an inner tube that is located around a passageway that opens at an axial end of the consumable so that the heating element is insertable into the passageway.

12. A consumable for use with apparatus for heating aerosolisable material to volatilise at least one component of the aerosolisable material, wherein the consumable comprises:
an outer tube; and
an inner member inside the outer tube, wherein the inner member comprises a hollow inner tube that defines a passageway configured to receive a heating element of an apparatus for heating aerosolisable material, wherein at least part of the inner member is spaced from the outer tube by at least one air gap, and wherein the inner member comprises aerosolisable material that is heatable to generate aerosol in the air gap;
wherein the consumable has at least one outlet for permitting the aerosol to pass out of consumable from the air gap.

13. The consumable of claim 1 or claim 12 , wherein the inner member comprises a carrier, and the aerosolisable material is affixed to the carrier.

14. The consumable of claim 1 or claim 12 , wherein the aerosolisable material comprises an amorphous solid.

15. A consumable for use with apparatus for heating aerosolisable material to volatilise at least one component of the aerosolisable material, wherein the consumable comprises:
an outer tube;
an inner member inside the outer tube, wherein the inner member comprises a hollow inner tube that defines a passageway configured to receive a heating element of an apparatus for heating aerosolisable material, wherein at least part of the inner member is spaced from the outer tube by at least one air gap; and
aerosolisable material comprising an amorphous solid that is heatable to generate aerosol in the air gap;
wherein the consumable has at least one outlet for permitting the aerosol to pass out of consumable from the air gap.

16. The consumable of claim 1, claim 12, or claim 15 , wherein at least one of the inner member and the outer tube is circular.

17. The consumable of clsim 1 , claim 12, or claim 15 , wherein the inner member and the outer tube are concentric.

18. The consumable of claim 1, claim 12, or claim 15 , wherein the hollow inner tube is located around a passageway that opens at an axial end of the consumable so that a heating element for heating the aerosolisable material is insertable into the passageway in use.

19. The consumable of claim 1, claim 12, or claim 15 , wherein the at least one outlet is at an axial end of the consumable.

20. The consumable of claim 1, claim 12, or claim 15 , comprising heating material that is heatable by penetration with a varying magnetic field to thereby heat the aerosolisable material.

21. The consumable of claim 20 , wherein the heating material comprises one or more materials selected from the group consisting of: an electrically-conductive material, a magnetic material, and a magnetic electrically-conductive material.

22. The consumable of claim 20 , wherein the heating material comprises a metal or a metal alloy.

23. The consumable of claim 20 , wherein the heating material comprises one or more materials selected from the group consisting of: aluminium, gold, iron, nickel, cobalt, conductive carbon, graphite, steel, plain-carbon steel, mild steel, stainless steel, ferritic stainless steel, molybdenum, silicon carbide, copper, and bronze.

24. The consumable of claim 20 , wherein at least one of the inner member and the outer tube comprises the heating material.
