Aerosol generating device

Abstract

An aerosol generating device generates an aerosol from aerosol-generating material. The device has a receptacle including a peripheral wall defining a heating zone for receiving at least a portion of the aerosol-generating material. An elongate rib protrudes into the heating zone. The elongate rib has a locating face arranged to space the heating zone from the peripheral wall and to provide an airflow path between the article and the peripheral wall. The elongate rib extends at least partially circumferentially about the peripheral wall.
