An apparatus for disseminating volatile liquid such as fragrance or insecticide into an atmosphere from a reservoir, the transfer to atmosphere being at least partially achieved by means of a transfer member having external capillary channels. The volatile liquid is one in which at least 30% by weight of the materials therein have a molecular weight of 175 maximum, and which has a surface tension of less than 40 dynes/cm. The transfer member is of plastics material having a surface energy of less than 45 dyne/cm. The combination allows for particularly efficient dissemination.
L'invention concerne un appareil destiné à la diffusion d'un liquide volatil, tel qu'un parfum ou un insecticide, dans une atmosphère, à partir d'un réservoir, le transfert dans l'atmosphère se faisant au moins partiellement par l'intermédiaire d'un élément de transfert comportant des capillaires externes. Le liquide volatil renferme au moins 30 % en masse de substances ayant un poids moléculaire inférieur ou égal à 175 et a une tension superficielle inférieure à 40 dyne/cm. L'élément de transfert est en plastique et a une tension superficielle inférieure à 45 dyne/cm. Cette combinaison permet une diffusion particulièrement efficace.
