ABSTRACT:
A dispensing package for a volatile composition such as a room deodorant and the like that comprises a container having at least two chambers. In one of the chambers is packaged a bed of inert solid, adsorbent granules having absorbed thereon a volatile ingredient for dispensing into the atmosphere. The container has an outlet vapor port in a wall of the chamber and a second vapor inlet port which communicates with a second chamber; the latter having a collapsible wall surface. A check valve is provided in the wall of the second chamber to permit air intake whereby volatile components adsorbed on the surface of the solid bed of granules can be dispensed into the atmosphere by pumping the collapsible wall of the second chamber, thereby forcing air through the bed of solid granules and desorbing of the the volatile adsorbate, which is dispensed into the atmosphere. Preferably, the bed of solid adsorbent is formed with a plurality of volatile components of different volatilities which are each adsorbed onto an inert carrier to provide a plurality of volatile-component-bearing, solid fractions which are blended together in preselected proportions to provide the desired proportional release rate of each of the volatile components.
