Abstract
An e-vapor device may include a reservoir, a heater, and a bimetallic actuator. The reservoir is configured to hold a pre-vapor formulation. The reservoir defines an outlet configured to release the pre-vapor formulation therefrom. The heater is configured to heat the pre-vapor formulation released from the reservoir to generate a vapor. The bimetallic actuator may be configured to seal the outlet of the reservoir when vaping is not occurring and configured to unseal the outlet when vaping is occurring.
