## Abstract

The cartridge includes a housing body, a hollow inner body extending longitudinally within the housing body and a reservoir configured to store a pre-vapor formulation. The reservoir is tubular and at least a portion of the reservoir is disposed between the housing body and the hollow inner body. A distal end of the reservoir defines a vent hole. A wick is in fluid communication with the reservoir and a heater is configured to vaporize the pre-vapor formulation in the wick.
