Abstract: A device for evaporating volatile substances includes a wick (1) impregnated with volatile substances and a heating element (2) that heats the wick (1) for purposes of evaporating said volatile substances. The device further includes a reflective element (3) for reflecting the heat from the heating element (2) to said wick (1). The heating element (2) can be preferably a resistor or a ceramic heater. The reflective element (3) directs substantially all the heat provided by the heating element to the wick, thereby preventing an excessive rising of the temperature of the surface of the device.

Abstract: The device (1) comprises a substrate (2) impregnated with volatile substances and a first film (3) that is impermeable to the volatile substances applied to one face of the substrate (2) and a second film (4) provided with a plurality of holes (5) applied to the other face of the substrate (2). The method for manufacturing said device 1 comprises the following steps: applying a first film (3) to a face of the substrate (1); impregnating the substrate (1) by depositing the volatile substances on the face of the substrate (1) that is not coated with the first film (3); leaving the volatile substances to fully impregnate the substrate (1); and applying a second film (4) provided with a plurality of holes (5) to the other face of the substrate (1). The device permits a more continuous diffusion of the volatile substances along time.

Abstract: An air freshener for vehicles includes a main body for holding a container for volatile substances and a foldable clip that may be placed in a substantially perpendicular position with respect to the main body. The foldable clip is rotatable with respect to the main body. The clip may always be connected with the main body, so that it is sold with it occupying a reduced space in the package. The clip may be rotated to be adapted to any kind of ventilation grids.

Abstract: A device for diffusion of volatile substances that includes a container for containing volatile substances, including the container, an aperture defining a sealing area, and a multilayer structure placed on the aperture. The multilayer structure includes a microporous membrane through which the volatile substances are diffused and a barrier layer that is removed before a first use. The multilayer structure also includes a sealing portion in contact with the sealing area. A device with a microporous membrane where the porosity of the membrane at the portion of the sealing area has been substantially reduced or eliminated to stop liquid transportation.
