Provided is an assembly for use in an apparatus for heating aerosolizable material to volatilize at least one component of the aerosolizable material to generate an inhalable aerosol. The assembly having a structure delimiting an opening through which aerosolizable material can be removably inserted into the apparatus, a door coupled to the structure and movable between an open position where access to the opening is unrestricted and a closed position where access to the opening is restricted, and a latching arrangement configured to hold the door in at least one of the open position and the closed position when the door is in the one of the open position and the closed position until an external force is applied, in use, to release the latching arrangement.

An aerosol provision device is described. A housing delimits a first opening at a first end of the housing through which to receive aerosol generating material and delimits a second opening at a second end of the housing. At least one heater is arranged within the housing and configured to heat the aerosol generating material received within the housing thereby to generate an aerosol. A hollow member is arranged within the housing and extends at least partially between the second and first openings. The hollow member has an end that faces the second opening and is configured to encourage the formation of liquid droplets.
