Abstract
An e-vaping section includes an outer housing, a supply reservoir, an inner tube, and a heater capable of vaporizing a pre-vapor formulation. The section includes a female threaded connector on an end of the e-vaping section that defines an air inlet positioned adjacent to threads of the connector. A power section includes an outer housing and a power supply, with a male treaded connector defining a vent hole. An assembled e-vaping device connects two e-vaping sections via the male and female threaded connectors causing the air inlet and vent hole to be in fluid communication with each other. A method of manufacturing an e-vaping device includes adjusting a cross-sectional area of the air inlets defined by the female threaded connector to adjust a resistance-to-draw (RTD) value for the device.
