Abstract
An aerosol delivery device comprises an aerosol-generation apparatus, including a heater and a fluid-transfer article. The fluid-transfer article has a reservoir for the holding an aerosol precursor, a wick arrangement to receive aerosol precursor from the reservoir, and a wick support element. The wick support element has at least one capillary bore therethrough. Hence, it allows aerosol precursor to pass from the reservoir to the wick in a capillary manner through the or each bore. Preferably, the heater makes abutting, unbonded contact with an activation surface of the wick soas to interact thermally therewith. This allows the heater to separable from the wick, for example, when the fluid-transfer article is separated from the rest of the device. This may be necessary when the aerosol precursor in the reservoir of the fluid transfer article has been consumed.
