A device for dispensing a volatile liquid as a vapor includes a porous support of natural or synthetic woven or non-woven fibre, porous glasses, porous plastics (optionally in film form), parchment, leather or rubber provided with an organopolysiloxane material which serves to close the pores of the support to the passage of liquid but permits the passage of vapour from the liquid. The volatile liquid is a perfume, insecticide, insect repellant, insect attractant, higher animal repellant, corrosion inhibitor, a germicidal agent or a medicament. A space treatment vapor emanating device is thus provided the external surface of which device is dry to the touch. |
