  • FRAGRANCE DIFFUSER, PARTICULARLY FOR SMALL SPACES, AND ASSOCIATED PRODUCTION PROCESS
    Publication number: 20150028124
    Abstract: A fragrance diffuser, particularly for small spaces, comprising a main body which forms an expansion seat, a containment chamber, which is segregated from the remaining part of the main body for containing a fluid, and a membrane which faces the external environment and is at least partially proximate to the expansion seat; at least one passage channel being interposed between the containment chamber and the expansion seat, provided internally with at least one barrier partition for the fluid. The fragrance diffuser has a closed configuration in which the partition is active to stop the passage of the fluid from the containment chamber to the expansion seat and a configuration for use in which the partition is inactive for the passage of the fluid from the containment chamber to the membrane, passing through the expansion seat.
