Abstract
An aerosol delivery device comprises: a storage for storing aerosol precursor liquid, the storage comprising an air bleed channel for permitting air to enter the storage as the storage empties of aerosol precursor in use; and a liquid transfer element for transferring aerosol precursor liquid from the storage to an aerosol generator, wherein the air bleed channel and the liquid transfer element are configured such that aerosol precursor liquid from the liquid transfer element forms an obstruction in the air bleed channel in use to reduce flow through the air bleed channel, the aerosol delivery device further configured such that the obstruction is removed to open the air bleed channel in response to a user drawing on the aerosol delivery device.
