Abstract (en)
[origin: EP3711599A1] 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 (35) of a first material, and has holes (37) therein which receive aerosol precursor from the first region. The second region 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 (41) of the fluid-transfer article. A heater (24) is proximate but spaced from the activation surface to heat it to release aerosol precursor in the form of a vapour therefrom. The heater is separable from the activation surface.
