An apparatus adapted to disseminate a volatile liquid, such as a fragrance, into an atmosphere in which its presence in vapour form is desired, the apparatus comprising a reservoir ( 1 ) of volatile liquid ( 2 ) and a porous wick that extends from the liquid in the reservoir to the atmosphere where it provides an evaporating surface, the wick being formed in at least two parts, at least one of which parts is in contact with the liquid and which comprises substantially no evaporating surface ( 3 ), and at least one other of which parts forms an evaporating surface ( 8,9 ), the parts being integral in the apparatus and that part comprising the evaporating surface being adapted to be movable either into liquid transfer contact or into non-liquid transfer separation with that part in contact with the liquid. The apparatus is simple, rugged, effective, cheap to make and easy to use. It is especially useful as an air freshener in motor vehicles.
