Abstract
An electronic smoking article includes a reservoir containing a liquid material and having an outlet, a capillary having a capillary inlet and a capillary outlet, the capillary inlet of the capillary in communication with the outlet of the reservoir, a heater operable to heat the capillary to a temperature sufficient to at least initially volatilize liquid material contained within the capillary, and a shuttle valve between the outlet of the reservoir and the capillary inlet. The shuttle valve is operable to prevent release of liquid material from the reservoir when the shuttle valve is in a closed position and is operable to release liquid material from the reservoir when the shuttle valve is in an open position.
