Patent attributes
There is disclosed a fluid-transfer article which is suitable for use as part of an aerosol-generating system of a type which may be used as a smoking substitute. 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, said activation surface being disposed at an end of said article configured for thermal interaction with a heater of an aerosol-generation apparatus. The activation surface includes at least one arcuate surface portion and is configured such that, when the fluid transfer article is arranged with respect to a said heating surface for thermal interaction therebetween, the or each said arcuate surface portion opposes said heating surface and is concave towards said heating surface. The arcuate surfaces form channels to receive an air stream to flow across the heated activation surface and become entrained with released aerosol precursor and then to be drawn towards a mouthpiece.
