Abstract

Abstract A dispenser for liquids controlling room odors in which limited amounts of liquid are deposited on a dispensing blade and the blade is brought into contact with a rough surface on a revolving disk of porous expanded plastic to intermittently compress the plastic in a circular path and distribute the liquid directly thereon for extensive permeation in the disk while propelling air to entrain and vaporize liquid from the remaining rough surface of the disk.
