1. An aerosol delivery device comprising:
a storage for storing an aerosol precursor;
a passive aerosol generator comprising an aerosol generator portion configured to receive the aerosol precursor from the storage;
an air flow passage configured to direct air past the aerosol generator portion to pick up the aerosol precursor from the passive aerosol generator portion to form an aerosol; and
a barrier arrangement for inhibiting evaporation of aerosol precursor when the barrier arrangement is closed, the barrier arrangement being openable to permit generation of aerosol.
