Abstract: A cartridge of an electronic vaping device includes a reservoir configured to store a pre-vapor formulation and a heating element configured to heat the pre-vapor formulation. The heating element includes a metal tube having a first end and a second end. The metal tube defines an opening therethrough. The metal tube includes a sidewall defining at least one spiral channel extending substantially continuously along a portion of the metal tube.

Abstract: 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.

Abstract: An apparatus for the automated filling of cartridges of e-vapor devices may include a filling drum configured to receive at least one cartridge of an e-vapor device. The apparatus may additionally include a needle assembly including at least one hypodermic needle. The needle assembly is configured to transition between a lowered state and a raised state. The lowered state is where the hypodermic needle is moved down into the cartridge, while the raised state is where the hypodermic needle is lifted up and away from the cartridge. The apparatus may further include a pump assembly configured to pump a pre-vapor formulation into the cartridge when the needle assembly is in the lowered state. The pump assembly may include a variable amplitude cam system configured to adjust an amount of the pre-vapor formulation for pumping to the cartridge without changing start and stop times for the pumping.
