Abstract
A device for delivering a metered quantity of vaporized liquid material to the surrounding atmosphere is disclosed. The device includes a reservoir for storing the liquid material, and a conduit in flow communication with the reservoir, with a portion of the conduit defining a dosing chamber for storing the metered quantity of the liquid material. The conduit further includes an impeding portion for restricting the flow of the liquid material from the dosing chamber toward the reservoir. An outlet nozzle is provided and is in flow communication with the dosing chamber. A thermal activator is disposed adjacent the dosing chamber for vaporizing the liquid material in the dosing chamber thereby ejecting the vaporized material through the outlet nozzle to the atmosphere.
