Publication number: 20240090089Abstract: A method of forming a heater assembly of an e-vaping device includes bending a wire to form a first lobe and bending the wire to form a second lobe. The first lobe and the second lobe form a generally sinuously-shaped heater having a first set of lobes and a second set of lobe. A first apex of the first lobe is generally opposite a second apex of the second lobe. The method may also include curling the first set of lobes towards the second set of lobes to form a heater having a substantially tubular form. The heater defines an opening there through.Type: ApplicationFiled: November 21, 2023Publication date: March 14, 2024Applicant: Altria Client Services LLCInventors: Christopher S.

Publication number: 20230405242Abstract: In the non-nicotine electronic vaping device, a saturation sensor measures at least one electrical characteristic of the wick between the heating element and the probe wire at a first time and a second time, wherein the at least one electrical characteristic includes a resistance, a capacitance, or both a resistance and a capacitance. Control circuitry is configured to cause the non-nicotine e-vaping device to: calculate a refill rate at which the non-nicotine pre-vapor formulation flows onto the wick based on the at least one electrical characteristic at the first time and the at least one electrical characteristic at the second time; determine that the refill rate is less than a threshold refill rate; and output a low non-nicotine pre-vapor formulation alert in response to determining that the refill rate is less than the threshold refill rate.Type: ApplicationFiled: September 6, 2023Publication date: December 21, 2023Applicant: Altria Client Services LLCInventors: Robert C.

Publication number: 20230371130Abstract: A cartridge for an e-vaping device includes a housing extending along a longitudinal axis of the cartridge, and an outlet-end insert coupled to the outlet end of the housing. The housing at least partially encloses a pre-vapor formulation reservoir and a vapor generator of the cartridge and further channels light via internal reflection through an interior of the housing. The outlet-end insert includes an outlet in flow communication with the vapor generator, directs the vapor generated by the vapor generator out of the cartridge through the outlet, and further emits the light channeled through the interior of the housing. One or more properties of the light are controllable.Type: ApplicationFiled: July 14, 2023Publication date: November 16, 2023Applicant: Altria Client Services LLCInventors: Christopher S.
