Abstract
A device for releasing a volatile substance into an environment in a controlled/metered manner. A reservoir made of a substance-absorbent material that is impregnated with a volatile substance in its liquid phase is located in a cavity open at the front surface of a container body made of a material non-permeable to the substance. A wood or wood-type panel permeable to the substance covers the cavity. A clip may be fixed to the back surface of the container body so that the device may be secured to a mounting surface. The device may be packaged with skin pack film such that a vapor barrier is formed, preserving/storing the substance until such time as opened/activated by the consumer. When activated, a volatilization mechanism is initiated wherein the panel absorbs the substance from the reservoir, the substance is introduced to ambient air, volatilized, released and, finally, dispersed throughout an environment.
