The aerosol container includes a valve, means for biasing the valve to a closed position, an outwardly extending valve stem having an internal passage in fluid communication with the valve and a discharge outlet in fluid communication with the stem passage. The container discharges a quantity of the contents therein through the valve, the passage and the discharge outlet upon relative movement between the valve stem and the container against the biasing means. The dispenser includes a housing having an aperture, means connected interiorly of the housing for maintaining the discharge outlet and valve stem in fixed alignment with the housing aperture, and means within the housing for automatically and periodically moving the aerosol container with respect to the valve stem against the biasing means to discharge a quantity of the contents of the container from the discharge outlet through the housing aperture.
