An apparatus adapted to disseminate volatile liquid into an atmosphere, the apparatus comprising at least one evaporation element having at least one evaporation surface bearing at least one capillary channel and at least one wick, the wick making contact with the evaporation element at a surface other than the one bearing the capillary channel. Liquid transfer contact between wick and capillary channel is provided by means of at least one capillary passage passing from that part of the evaporation element contacting the wick to the capillary channel. The evaporation element is preferably a capillary sheet. The apparatus allows the use of wicks that are smaller than usual, with no loss in efficiency of dissemination. It is also cheaper and more convenient to manufacture.
