    摘要: A volatile substance dispensing device (101) and method of fabrication thereof based on a container (201) sealed by a membrane layer (220) with at least one perimetral channel (103) which prevents lateral diffusion of the volatile substance during storage. The at least one perimetral channel (103) is at least partially filled with blocking means such as glue (303) or a protrusion (302) of a separation layer (230) produced by applying heat welding during fixation to the container (201). The dispensing device (101) further comprises a removable barrier layer (240) on top of the separation layer (230).

    摘要: 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.
