DISSEMINATING DEVICE FOR VOLATILE LIQUID

摘要

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.
