  • the effect produced inside the passenger compartment is rather limited, in view of the fact that the ashtray is normally closed and the scented substance is gradually covered by trash, ash and cigarette tabs.
  • a second type provides for deodorizing devices designed to be hung in the passenger compartment, generally at the rear-view mirror.
  • these devices consist substantially of a piece of absorbent card impregnated with fragrance, which over time releases said fragrance through its opposite breathable surfaces. When the entire scented substance has evaporated, the card no longer performs its function and therefore must be replaced.
