Abstract: An electronic smoking article or electronic vaping 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.

Abstract: An electronic smoking article includes a heater in communication with a liquid supply reservoir including liquid material and operable to heat the liquid material to a temperature sufficient to volatilize the liquid material contained therein and form an aerosol. The volatilized material flows through a sheath flow and aerosol promoter insert that is operable to cool the aerosol, reduce the particle size of the aerosol and increase the delivery rate of the aerosol.

Abstract: The method includes supporting at least one first heater, and at least partially supporting at least one portion of at least one first wick, using a support plate in an e-vaping section, configuring the at least one first wick to transfer a pre-vapor formulation from a reservoir to the at least one first heater, forming an electrical connection between the at least one first heater and a terminal that is electrically connectable to a power supply, and positioning the support plate nearer a downstream end than an upstream end of the reservoir relative to a normal direction of airflow through the e-vaping section during use, a major surface of the support plate being transverse to the normal direction of airflow.
