Abstract
A combined spray and evaporative air freshener or the like device which comprises a generally cylindrical ornamental shroud open at one end and having an apertured top, for application to a conventional aerosol spray container having a manually depressible valve for actuating the same. The top of the shroud has an interior bottom opening cup which in general surrounds the actuator for the valve and receives the spray upon depression of the valve stem, the spray falling in droplets into the valve cup. An impregnated absorptive ring may be placed in the cup in position to be impinged upon by the spray in situ, the impregnated material being activated by the spray when the shroud is depressed, releasing additional fragrance into the air. The ring may also be placed in the usual valve cup surrounding the valve and in this case it is activated by the spray material dripping on it.
