An apparatus adapted to disseminate volatile liquid into an atmosphere by heating and evaporation, and simultaneously to provide illumination, comprising (a) a source of heat and light comprising at least one electric light bulb 4; (b) a reservoir 2 for holding the liquid 7, having (i) an upper end comprising an opening leading to the atmosphere, this opening being covered by a mesh 11 defining a series of apertures; (ii) a lower end in which is formed a re-entrant portion whose shape conforms closely to the exterior form of the bulb, such that, in place, most of the glass surface of the bulb is surrounded, at least that part of the reservoir in the vicinity of the bulb being translucent or transparent; and (c) a volatile liquid that is transparent or translucent, and that has a viscosity under conditions of use such that it will be retained by a mesh of having apertures of the same size as those of the mesh in the upper end. The apparatus provides an effective and aesthetically attractive method of disseminating liquids such as fragrances and insecticides into the atmosphere, and it has the added advantage of safety when inadvertently knocked over.
