1. A carrier for an aerosol precursor, the carrier comprising:
a housing for engagement with an aerosol-generating apparatus, said housing being 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; and
a fluid-transfer article provided within the housing, the fluid-transfer article comprising: 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 heating surface of an aerosol-generation apparatus; said activation surface including at least one arcuate surface portion and being 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.
