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: An e-vapor device may include a vaporizer assembly that is detachably coupled to a battery assembly via a connector. The connector may include a male connecting portion and a female connecting portion. The male connecting portion may include mating arms extending from a rim of the male connecting portion. The female connecting portion may include an inner surface and lugs on the inner surface. The mating arms of the male connecting portion are configured to engage the lugs of the female connecting portion so as to electrically couple the vaporizer assembly and the battery assembly. A knurled pattern may also be provided on an outer surface of the male connecting portion and/or female connecting portion so as to conformally interface with a reversed pattern on an inner surface of the vaporizer assembly and/or the battery assembly.

Abstract: A folded heater of an electronic vaping device includes a first plurality of U-shaped segments arranged in a first direction and defining a first side of the heater and a second plurality of U-shaped segments arranged in the first direction and defining a second side of the heater. The second side is substantially parallel to the first side. The heater also includes a first lead portion and a second lead portion. The first plurality of U-shaped segments, the second plurality of U-shaped segments, the first lead portion, and the second lead portion are a single integral member.
