Abstract: This is a device for dispersing a vapor, such as a deodorant or fragrant vapor, into the air when a movable element, such as the actuation arm of a flush toilet, is moved from a usual `at rest` position. A switch responsive to movement of the movable element from its `at rest` position closes a circuit which energizes an electrically actuated means, such as a motor or a solenoid operated lever, which when actuated opens the valve of a container from which a vapor of a deodorant or fragrance is dispersed under pressure. The device is particularly adapted for dispersing a deodorant into the air in a bathroom or lavatory when the toilet therein is flushed.
