<p>A subject of the present invention is a device for the diffusion of a volatile product, such as a perfume, in liquid phase. This device is characterized by the use of a microporous polymeric membrane (4) with a pore diameter comprised between 0.1 and 5 micrometers and rendered super-hydrophobic so as not to be wetted by the liquid phase. This membrane can constitute a vertical wall of a container (3) containing the liquid phase. <IMAGE></p> |
