Abstract
Abstract A method of creating odors in which the individual components from which the odor is to be formed, in volatile form, are stored in their own individual receptacles, controlled amounts of said components being released, by evaporation, from their individual storage receptacles, with the various evaporation products being subsequently intermixed to produce the desired odor by first intermixing individual evaporation products into respective streams of air and thereafter intermixing the respective streams of air to effect an intermixing of the various evaporation products therein contained, and a device for practicing such method employing means for producing a plurality of individual air streams, novel individual storage means for respective components to be employed in the creation of such odor, each individual storage means having means associated therewith for effecting a controlled release by evaporation of the associated stored component, such storage means being so arranged with respect to the air stream that the release of the evaporation products of each of the various stored components is effected into a different air stream, means being provided for effecting an intermixture of such air streams subsequent to the introduction therein of the various components.
