    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: The device for diffusing volatile substances, comprises a container (1) that contains a volatile substance (2); a perforable sheet (3) that closes at least a portion of said container (1); at least one perforating element (4) that can perforate said perforable sheet (3); and a porous element (5) that is impregnated with the volatile substance (2) when the perforable sheet (3) is perforated; wherein the porous element (5) comprises at least one weakened area (6) in correspondence with said at least one perforating element (4).
    It permits to provide a device for diffusing volatile substances where an accidental leakage is avoided.

    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.

    摘要: Hand dispenser for cleaning, disinfectant and/or perfuming liquid products, of the type including a container having a dispensing button which operates a piston of a piston pump for dispensing liquid product from a nozzle, and a seat for a refill including a bottle containing a sprayable liquid formulation, the piston pump being indifferently housed in the container or in the refill. The container includes a cover hinged on the container, for closing the seat of the refill, and a mechanical coupling between the cover and the dispensing button, which causes the dispensing button to raise beyond its ordinary rest position, when the cover is opened, and to lower to its ordinary rest position, when the cover is closed.
