Electronic vaping device
A cartridge of an electronic vaping device includes a housing extending in a longitudinal direction. The housing includes a sidewall, a transverse wall at the first end of the sidewall, and an inner tube integrally formed with the housing. The sidewall is generally cylindrical and a first end and a second end. The transverse wall includes at least one outlet therein. The inner tube extends in the longitudinal direction. The inner tube is concentrically positioned with respect to the sidewall. The inner tube communicates with the at least one outlet. The cartridge also includes a reservoir between the sidewall and the inner tube. The reservoir is configured to contain a pre-vapor formulation.
