Abstract
Abstract In automatically discharging an effective substance, such as a deodorizing agent, from an aerosol container into a normally closed room, such as a bathroom, closet and the like, the aerosol container is pivotally mounted in a rigid holder secured to the door of the room so that the container provides a flywheel mass which discharges the effective substance when the door is displaced from its normally closed position. Preferably, a tilting valve forms the discharge member from the container, the container can be supported by the holder in the upright or inverted position. In effecting a slow release of the effective substance, it can be sprayed into a porous sponge-like member secured in the holder from which it slowly evaporates. Further, for signalling that the container is empty, a whistle device can be arranged at its outlet opening for providing a whistle tone when the container is empty or a whistle tone can be provided at each discharge from the container so that the tone is no longer emitted when the container becomes empty.
