Abstract: An aerosol-generating device includes a housing that defines a capsule-receiving cavity, a lid configured to close the housing, and a replaceable mouthpiece coupleable to the lid such that air entering the housing and drawn through the capsule-receiving cavity exits out of the mouthpiece. The lid may be fixedly coupled to the housing at a first point and releasably coupleable to the housing at a second point. The capsule-receiving cavity may have a first end having a first width, and a second end have a second width that is different from the first width. The capsule-receiving cavity may be tapered between the first end and the second end. The mouthpiece may be coupleable to the first end. One or more alignment member may be disposed at or towards the second end. The alignment members may include seals and/or electrical connections and/or flat surfaces and/or angled surfaces.

Abstract: An apparatus is provided to heat smokeable material (3) to volatilise at least one component of the smokeable material, wherein the apparatus comprises a chemical heat source (2); and an actuating mechanism (6), and wherein the actuating mechanism, upon actuation, activates the heat source which heats the smokeable material. A method of heating a smokeable material to volatilise components of the smokeable material for inhalation is also provided, and use of a chemical heat source to volatilise components of the smokeable material for inhalation.
