Abstract: Described herein is a cartridge for use with apparatus for heating smokable material to volatilize at least one component of the smokable material. The cartridge comprises a housing defining a chamber, smokable material located in the chamber, and a mass of thermal insulation material located between the smokable material and the housing. Also disclosed is apparatus for heating smokable material to volatilize at least one component of the smokable material. The apparatus comprises an assembly having an interface, and the cartridge, wherein the cartridge is for co-operating with the interface of the assembly.

Abstract: Described herein is a heating device for use with apparatus for heating smokable material to volatilize at least one component of the smokable material. The heating device comprises a heating element, and smokable material bonded to the heating element. The heating element comprises a layer of electrically-conductive material, a first layer of polyimide, and a second layer of polyimide. The layer of electrically-conductive material is located between the first and second layers of polyimide. Also described are cartridges comprising the heating device, apparatus comprising the heating device and methods of manufacturing the heating device.

Abstract: A device is provided comprising a heat source material which is a phase change material and which undergoes an exothermic phase change upon activation by an activating agent to generate heat, a heat source chamber holding the heat source and an activation chamber providing the activating agent, and a barrier separating the interior of the heat source chamber from the interior of the activation chamber, wherein the activation chamber is deformable and wherein deformation of the activation chamber causes rupture of the barrier to allow contact between the activating agent and the heat source material. Embodiments also provide an activation chamber for use in the device and comprising an activating agent to trigger activation of a heat source material.
