An apparatus adapted to disseminate volatile liquid, such as a fragrance, into an atmosphere comprises a reservoir (1) containing volatile liquid and, extending into and therefrom, an essentially cylindrical liquid transfer member (4) that transfers liquid from the reservoir to an evaporating surface (6) through which the transfer member passes by means of a hole in the evaporating surface. The evaporating surface comprises a rigid sheet that extends essentially laterally from the transfer member and bears on its surface capillary channels adapted to accept liquid from the transfer member and spread it over the surface of the evaporating surface. The transfer member is elastically compressible in diameter, with a diameter in its non-compressed form greater than that of the hole, and, prior to putting into service of the apparatus, is held in a compressed form of diameter smaller than that of the hole, such that, when the compression is released, the transfer member expands into liquid transfer contact with the evaporating surface. This ensures optimal liquid transfer contact between transfer member and evaporating surface.
L'invention concerne un appareil conçu pour disséminer un liquide volatil, tel qu'une fragrance, dans une atmosphère et comprenant un réservoir (1) renfermant un liquide volatil et un élément de transfert de liquide, s'étendant dans le réservoir et à partir de celui-ci, en forme générale de cylindre (4) transférant le liquide du réservoir dans une surface d'évaporation (6) à travers laquelle l'élément de transfert passe, au moyen d'un trou ménagé dans la surface d'évaporation. Celle-ci comprend une feuille rigide s'étendant de manière sensiblement latérale à partir de l'élément de transfert et supportant sur sa surface des canaux capillaires conçus pour accepter le liquide provenant de l'élément de transfert et pour le diffuser sur la surface de la surface d'évaporation. L'élément de transfert est élastiquement compressible au niveau du diamètre, lequel, dans sa forme non comprimée, est supérieur à celui du trou, et avant de mettre l'appareil en service, ledit élément est maintenu dans sa forme comprimée dans laquelle son diamètre est inférieur à celui du trou, afin que, lors de la libération de la compression, l'élément de transfert s'étende en contact de transfert de liquide avec la surface d'évaporation, garantissant ainsi un contact de transfert de liquide optimal entre l'élément de transfert et la surface d'évaporation.
