A smoking article (110) comprises a rod (12) of smokable material in axial alignment with a liquid release device (118), the device comprising: a stationary porous element (20) fixed with respect to the rod (12); a mobile porous element (22) axially aligned with and axially movable relative to the stationary porous element (20); and at least one frangible capsule (34) of liquid retained between the porous elements (20), (22), whereby axial movement of the mobile element (22) from a first position in which the capsule (34) is intact toward the stationary element (20) to a second position causes the capsule (34) to rupture and release the liquid into the porous elements (20), (22) and in which the mobile element (22) is restrained against undesired axial movement in at least one, preferably both, of the first and second positions. |
