ABSTRACT:
A passive aromatic substance dispenser is described. A highly absorbent rod shaped wick, held within a hermetically sealed tube, serves as a fragrance dispensing reservoir in contact with an efficient fragrance diffuser, and also serves as a convenient means for suspending the diffuser in a selected area to be fragranced. When fragrancing an area is not desired, closing the housing for the diffuser seals the diffuser from ambient air currents, protecting the aromatic substance from evaporating from the diffuser. The vacuum that develops within the tube due to the absorption of aromatic substance from the rod and into the diffuser prevents draining of the fragrance material from the rod and into the diffuser when not required, thus providing self regulation of the fragrance material by the dispenser.
