A housing shell (120) configured to receive a supply packet (108) comprising a pre-vapor formulation, a mouthpiece secured to an end of the housing shell (120), a puncture device (110) in the housing shell (120), And an evaporator device comprising a heater structure in the housing shell (120) and disposed in thermal contact with the prevapor formulation. The mouthpiece is configured to move from the retracted position to the retracted position. The lancing device (110) is configured to pierce the supply packet (108) to release the pre-vapor formulation as the mouthpiece transitions to the retracted position. The heater structure is configured to vaporize the prevapor formulation to produce steam. [Selection] Figure 1
