Abstract

An aerosol delivery system has a fluid transfer article with a first region for holding an aerosol precursor, and a wick which extends from the reservoir and makes abutting unbonded contact with a heating region of a heater of the aerosol-delivery system. There may be a seal closing the reservoir, with the wick extending through the seal so that aerosol precursor may pass from the reservoir through the wick to the heating surface. When the heater is active, that aerosol precursor will be heated to form an aerosol or vapour. When the user sucks or inhales through the aerosol delivery system, air flows through the air-flow pathway across the heating surface of the heater, so that aerosol passes from the heater and/or wick to the user in the air-flow. The heating region of the heater may be flexible. It may therefore deform due to the contact between itself and the wick ensuring good contact therebetween. The fluid-transfer article and the heater may be separable, to allow the fluid-transfer article to be replaced. The heating region includes at least one electrically conductive filament which generates heater when electrical current is passed therethrough. The or each filament has a coating of electrically insulating material thereon, the coating having a thickness not greater than 50µm.
