Patent number: 10258089Abstract: The present disclosure relates to an electronic smoking article that provides for improved aerosol delivery. Particularly, the article comprises a wicking element useful for improving delivery of aerosol precursor to a heating element. In particular, the wick can take on a brush-like configuration. The present disclosure further relates to methods of forming an aerosol in a smoking article.Type: GrantFiled: September 14, 2017Date of Patent: April 16, 2019Assignee: RAI Strategic Holdings, Inc.Inventors: Stephen Benson Sears, Grady Lance Dooly, David William Griffith, Jr., Andries Don Sebastian, Yi-Ping Chang

Publication number: 20190098938Abstract: The present invention provides a conductive substrate useful for Joule heating, such as in an electronic smoking article. Particularly, the invention provides a resistive heating element formed of a conductive substrate. The conductive substrate comprises an electrically conductive material and a carbonaceous additive, such as a binder material. The conductive substrate is carbonized in that it is subjected to calcining conditions to effectively reduce the carbonaceous additive to its carbon skeleton. It has been found that such carbonized substrate has surprisingly improved resistance properties in relation a substrate of the same formulation that is not carbonized. The carbonized substrate can include an aerosol precursor material. The formed resistive heating element can be included in an electronic smoking article to simultaneously provide resistive heating and aerosol formation with a single, unitary component.Type: ApplicationFiled: December 3, 2018Publication date: April 4, 2019Inventors: David William Griffith, JR., Yi-Ping Chang, Calvin W. Henderson, Ricky Lee Montgomery, Walter Charles Liebscher, II, Chandra Kumar Banerjee, Paul E. Braxton, Stephen Benson Sears, Kenneth Allen Beard, Timothy Brian Nestor, Balager Ademe, Frederic Philippe Ampolini, Dennis Lee Potter

Publication number: 20190090548Abstract: The present disclosure provides components useful in heating, particularly heating of an aerosol precursor solution so as to vaporize the solution and form an aerosol. The disclosure particularly provides an electrically conductive, porous carbon heater. The heater may be combined with an aerosol precursor transport element that also is formed of carbon. The heater and transport element may form an atomizer that can be useful in an electronic smoking article, such as in a cartridge that is adapted for attachment to a control body. In some embodiments, the disclosure provides a cartridge of an electronic smoking article, the cartridge being formed substantially completely of carbon.Type: ApplicationFiled: November 30, 2018Publication date: March 28, 2019Inventors: Michael F. Davis, Balager Ademe, Chandra Kumar Banerjee, Susan K. Pike, David William Griffith, JR., Steven Benson Sears, Evon L. Crooks, Karen V. Williams, Timothy Brian Nestor, David Bovender

Patent number: 10231488Abstract: A smoking article may include a cigarette incorporated within an electrically powered aerosol generating device that acts as a holder for that cigarette. The smoking article possesses at least one form of tobacco. The smoking article also possesses a mouth-end piece that is used by the smoker to inhale components of tobacco that are generated by the action of heat upon components of the cigarette. A representative smoking article possesses an outer housing incorporating a source of electrical power (e.g., a battery), a sensing mechanism for powering the device at least during periods of draw, and a heating device (e.g., at least one electrical resistance heating element) for forming a thermally generated aerosol that incorporates components of tobacco. During use, the cigarette is positioned within the device, and after use, the used cigarette is removed from the device and replaced with another cigarette.Type: GrantFiled: January 24, 2018Date of Patent: March 19, 2019Assignee: RAI Strategic Holdings, Inc.Inventors: John Howard Robinson, David William Griffith, Jr., Billy Tyrone Conner, Evon Llwellyn Crooks, Dempsey Bailey Brewer, Jr.
