Abstract (en)

[origin: EP3711605A1] An aerosol delivery system has a fluid-transfer article (34) which holds an aerosol precursor, and which is arranged to transfer the aerosol precursor to a second region (36) of the fluid-transfer article. The second region has a first part (36a) adjacent to a first region of a first material, and has holes (37) therein which receive aerosol precursor from the first region. The second region (36) also has a second part (36b) of a second material, which second part is adjacent to the first part, is of porous material and extends across the holes in the first part. The second material is resistant to higher temperatures than the first material. Since the second part of the second region is porous, aerosol precursor will pass therethrough from the holes to an activation surface of the fluid-transfer article. A heater (24) contacts part of that activation surface to heat it to release aerosol precursor in the form of a vapour therefrom. The heater is not bonded to the activation surface, but is separable therefrom. The second part of the second region has one or more recesses (38) therein opening towards the heater. The recesses form at least one gap between the activation surface and the heater, with the at least one gap forming at least one air-flow pathway along the activation surface.
