Abstract

A consumable article for use with an apparatus arranged to heat aerosolizable material to volatilize at least one component of the aerosolizable material is disclosed. The consumable article has an outer shell and an inner shell within the outer shell. The inner shell contains aerosolizable material. The consumable article also has a thermally insulating layer separating the inner shell from the outer shell.

First claim

The invention claimed is:

1 . A consumable article for use with an apparatus arranged to heat aerosolizable material, the consumable article comprising:
an outer shell; an inner shell within the outer shell, the inner shell containing the aerosolizable material; a thermally insulating layer separating the inner shell from the outer shell; and a heater arranged to heat the aerosolizable material, wherein the heater forms a layer that is: positioned between the inner shell and the aerosolizable material, embedded within the inner shell, or formed by the inner shell, and wherein the heater comprises a susceptor material that is heatable by penetration with a varying magnetic field to heat the aerosolizable material.

2 . The consumable article according to claim 1 , further comprising a spacer located between the inner shell and the outer shell, the spacer being arranged to provide a separation between the inner shell and the outer shell.

3 . The consumable article according to claim 2 , wherein the spacer comprises a material having a thermal conductivity less than 5 W/m·K.

4 . The consumable article according to claim 2 , wherein the spacer comprises one or more materials chosen from a cardboard material, a paper material, a wood material, and a plastics material.

5 . The consumable article according to claim 2 , wherein the spacer comprises a plurality of spacer elements arranged circumferentially about an outer surface of the inner shell.

6 . The consumable article according to claim 2 , wherein the spacer comprises a corrugated material arranged circumferentially about an outer diameter of the inner shell.

7 . The consumable article according to claim 6 , wherein one or more inner portions of the corrugated material contact the inner shell and one or more outer portions of the corrugated material contact the outer shell.

8 . The consumable article according to claim 1 , wherein the inner shell and outer shell are cylindrical, the inner shell having a cross-sectional diameter less than a cross-sectional diameter of the outer shell.

9 . The consumable article according to claim 1 , further comprising a flow channel comprising a path between the inner and outer shells, the flow channel fluidically connecting a first end of the consumable article and a second end of the consumable article opposite the first end.

10 . The consumable article according to claim 1 , wherein the inner shell comprises a paper material and the susceptor material is bonded to an inner surface of the inner shell.

11 . The consumable article according to claim 1 , wherein the susceptor material comprises aluminum.

12 . The consumable article according to claim 1 , wherein the heater comprises a plurality of heating elements.

13 . The consumable article according to claim 1 , wherein the outer shell comprises a paper material.

14 . The consumable article according to claim 1 , wherein the thermally insulating layer comprises air and/or a solid-based thermally insulating material.

15 . An apparatus arranged to heat aerosolizable material to volatilize at least one component of the aerosolizable material, the apparatus comprising a housing and the consumable article according to claim 1 , the housing arranged to receive the consumable article.

16 . The apparatus according to claim 15 , further comprising a resistive heater arranged to be inserted into the aerosolizable material contained within the inner shell.

17 . The consumable article according to claim 1 , wherein the outer shell extends along a substantial length of the consumable article.

18 . The consumable article according to claim 1 , further comprising a plurality of spacers, wherein at least a portion of the thermally insulating layer is located longitudinally between the plurality of spacers.

19 . The consumable article according to claim 1 , wherein the heater is configured to be heated without direct electrical contact by the apparatus.

20 . An apparatus arranged to heat aerosolizable material to volatilize at least one component of the aerosolizable material, the apparatus comprising a consumable article, the consumable article comprising:
an outer shell; an inner shell within the outer shell, the inner shell containing the aerosolizable material; and a heater element arranged for heating the aerosolizable material, wherein the inner shell and outer shell are separated by a thermally insulating layer, wherein the heater element forms a layer that is:
positioned between the inner shell and the aerosolizable material,
embedded within the inner shell, or
formed by the inner shell,
wherein the heater element comprises a susceptor material that is heatable by penetration with a varying magnetic field to heat the aerosolizable material.
