ABSTRACT:
A device for the controlled dispensation and unattended evaporation of volatile liquids includes a housing that accommodates a reservoir charged with a volatile liquid. The reservoir has an outlet for releasing the volatile liquid from a lower end of the reservoir. A valve mounted on the reservoir controls the flow of the volatile liquid through the reservoir outlet. The valve allows a controlled quantity of the volatile liquid, in the form of discrete droplets, to be gravitationally delivered, on demand, to an absorbent matrix. A matrix housing supports the matrix below the reservoir outlet. The absorbent matrix absorbs volatile liquid that the outlet delivers and dispenses the volatile liquid as a vapor to an external environment. The absorbent matrix dispenses the vapor via a ventilator that may be either releasably or integrally mounted to either the matrix housing or the housing that accommodates the reservoir.
