Abstract: A carrier, apparatus and method for making an aerosol precursor liquid suitable for aerosolized delivery by a device such as an electronic cigarette. A carrier is fluid permeable and comprises a tobacco-derived medium for carrying a functional component, the medium being configured to release the functional component into a fluid to provide an aerosol precursor liquid infused with the functional component. A method for mixing an aerosol precursor liquid for aerosolized delivery of a functional component by an aerosol delivery device comprises bringing the tobacco-derived medium carrying the functional component into contact with fluid and allowing the fluid to saturate the medium to thereby cause the medium to release the functional component into said fluid to form an aerosol precursor liquid infused with the functional component. A receptacle comprising a chamber for the carrier is provided for mixing the aerosol precursor liquid. Example functional components include nicotine and nicotine salts.

Abstract: An aerosol-delivery system having: an aerosol-generation apparatus with a receptacle for receiving a carrier; a heater; and a carrier for an aerosol precursor with a housing for location in said receptacle. Said housing is configured to provide a fluid pathway between a first end that is disposed in fluid engagement with an inlet of said aerosol-generating apparatus and a second end that is disposed in fluid engagement with an outlet of said aerosol-generating apparatus. A fluid-transfer article is located within said housing, the fluid-transfer article having a first region for holding an aerosol precursor and for transferring said aerosol precursor to an activation surface of a second region of said article, said activation surface disposed at an end of said carrier configured for thermal interaction with a heater of said aerosol-generation apparatus.

Abstract: An aerosol-generation apparatus, which is suitable for use as part of an aerosol-generating system of a smoking substitute type. The apparatus comprises a heater having a planar heating surface, and is configured to receive an aerosol precursor carrier for thermal interaction the heating surface. The heater comprises a heating element at the heating surface, and the heating surface comprises a fluid transport region adjacent the heating element. The fluid transport region is configured to move liquid across the heating surface towards the heating element.

Abstract: The present invention relates to an inhaler comprising: an assembly including a heater element arranged in the inhaler to be proximal to a substrate region configured for supporting a vapour or atomiser precursor substrate; wherein the assembly is configured such that the heater element is operative to achieve and maintain a target temperature in the substrate region throughout a period corresponding to a plurality of consecutive uses of the inhaler.

Abstract: There is disclosed a fluid-transfer article which is suitable for use as part of an aerosol-generating system. The fluid-transfer-article comprises a first region for holding an aerosol precursor and for transferring said aerosol precursor to an activation surface of a second region of said article. The activation surface is disposed at an end of said article configured for thermal interaction with a heater of an aerosol-generation apparatus. At least the second region of the fluid-transfer article is formed from a polymeric wicking material.

Abstract: There is disclosed a device for nicotine delivery, comprising: a vapour outlet conduit for coupling to, and for fluid communication with, a vapour creation system, said vapour outlet conduit defining a fluid passage therethrough for delivery of vapour from a vapour creation system to a user; wherein said vapour outlet conduit comprises a nicotine carrier unit region configured to accept a nicotine carrier unit and retain said nicotine carrier unit in said fluid passage. Also disclosed is a system for nicotine delivery and kits-of-parts for assembling the device and system.
