Abstract

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