Abstract
An aerosol dispensing device comprises a tubular body that provides a plenum, a mouthpiece having an outlet, a valve for dispensing fluid from a canister as an aerosol with relatively large and small droplet sizes into the plenum for supply to a user through the mouthpiece, and a baffle arrangement that provides first and second passageways each coupled at one end to the plenum and so configured to receive relatively small and large size droplets in the aerosol respectively, the other end of the first passageway extending to the outlet in the mouthpiece to supply the small size droplets to the user, and the other end of the second passageway being closed to inhibit passage of the large size droplets to the mouthpiece outlet, and containing a absorbent pad to prevent leakage of liquid from the canister. The pad may be pre-loaded with a flavourant.
