A device adapted to provide volatile liquid material to an atmosphere, comprising a reservoir containing volatile liquid material, a rod-like transfer member extending therefrom and adapted to transfer liquid from the reservoir, and at least one diffusion surface adapted to receive the liquid from the transfer member and facilitate its evaporation into the atmosphere, the diffusion surface extending essentially laterally from the transfer member and comprising at least one non-integral, non-porous sheet bearing a surface capillarity, which sheet has an extent and a capillarity sufficient to allow an appropriate evaporation. The device is cheap and easy to construct, versatile and diffuses odor without major changes of the odor over time.
A device adapted to provide volatile liquid material to an atmosphere, comprising
A device according to 2, wherein the diffusion surface is mounted on the transfer member by means of an aperture in the diffusion surface, the aperture having a shape that allows the placing of the diffusion surface on the transfer member such that it is in liquid transfer contact therewith.
A device according to 3, wherein the diffusion surface is mounted on the transfer member by means of an aperture in the diffusion surface, the aperture having a shape that allows the placing of the diffusion surface on the transfer member such that it is in liquid transfer contact therewith.
A device according to 4, wherein the diffusion surface is mounted on the transfer member by means of an aperture in the diffusion surface , the aperture having a shape that allows the placing of the diffusion surface on the transfer member such that it is in liquid transfer contact therewith.
