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. ## Claims ### Claim 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. ### Claim 2 (depends on 1) 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. ### Claim 3 (depends on 2) The consumable article according to claim 2, wherein the spacer comprises a material having a thermal conductivity less than 5 W/m·K. ### Claim 4 (depends on 2) 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. ### Claim 5 (depends on 2) 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. ### Claim 6 (depends on 2) The consumable article according to claim 2, wherein the spacer comprises a corrugated material arranged circumferentially about an outer diameter of the inner shell. ### Claim 7 (depends on 6) 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. ### Claim 8 (depends on 1) 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. ### Claim 9 (depends on 1) 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. ### Claim 10 (depends on 1) 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. ### Claim 11 (depends on 1) The consumable article according to claim 1, wherein the susceptor material comprises aluminum. ### Claim 12 (depends on 1) The consumable article according to claim 1, wherein the heater comprises a plurality of heating elements. ### Claim 13 (depends on 1) The consumable article according to claim 1, wherein the outer shell comprises a paper material. ### Claim 14 (depends on 1) The consumable article according to claim 1, wherein the thermally insulating layer comprises air and/or a solid-based thermally insulating material. ### Claim 15 (depends on 1) 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. ### Claim 16 (depends on 15) The apparatus according to claim 15, further comprising a resistive heater arranged to be inserted into the aerosolizable material contained within the inner shell. ### Claim 17 (depends on 1) The consumable article according to claim 1, wherein the outer shell extends along a substantial length of the consumable article. ### Claim 18 (depends on 1) 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. ### Claim 19 (depends on 1) The consumable article according to claim 1, wherein the heater is configured to be heated without direct electrical contact by the apparatus. ### Claim 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.
