ABSTRACT:
A vapor dispersing device in which evaporative dispersion of volatile and diffusive components of an air treating agent is regulated over an extending period by the use of a container, for the agent, into which at least one rigid porous wick extends to transfer the agent from the container to a porous plastic element from the surface of which dispersion of the agent will occur by means of evaporation, the surface of the element being impregnated with an occluding agent, the evaporation rate of which is chosen, relative to rate of deposition on non-volatile components of the air treating agent in the element, to result in an even dispersion rate over a desired operating period.
