Patent number: 11700877Abstract: Cigarettes are provided which contain a filtering system and flavorants encapsulated with polyvinyl acetate, wherein deactivation of a sorbent by the flavorant is reduced through the encapsulation of the flavorant within the polyvinyl acetate. A preferred flavorant is menthol. The encapsulated flavorants are prepared by mixing at least one flavorant with polyvinyl acetate and a solvent, such as ethanol, and forming the encapsulated flavorants. Methods of making cigarettes and smoking the articles are also provided.Type: GrantFiled: March 6, 2020Date of Patent: July 18, 2023Assignee: Philip Morris USA Inc.Inventors: Ulrike Becker, Tony Howell, Lixin Xue, Georgios D. Karles, Jay A. Fournier

Patent number: 7518123Abstract: A heat capacitor for a capillary aerosol generator comprises a phase change material that changes phases at a temperature approximately equal to a temperature sufficient to volatilize liquid material in a capillary passage of the capillary aerosol generator. The phase change material stores heat, which can be used to generate aerosol either continuously or intermittently over a given time. The use of stored heat in the phase change material to generate aerosol over time enables operation of the capillary aerosol generator remote from a large energy source.Type: GrantFiled: September 25, 2006Date of Patent: April 14, 2009Assignee: Philip Morris USA Inc.Inventors: Tony Howell, Clover Hariaczyi, Marc Belcastro

Publication number: 20070023058Abstract: A method of forming a liquor comprising tobacco solutes, the method comprising extracting tobacco solutes from tobacco by flowing an extraction solvent through tobacco to form a tobacco solutes-rich extraction solvent and a tobacco solutes-poor tobacco, and forming tobacco solutes-rich liquor by flowing the tobacco solutes-rich extraction solvent through an entrapment solvent, wherein the tobacco solutes comprise nicotine and at least one tobacco flavor compound and/or tobacco aroma compound and the liquor comprises the tobacco solutes dissolved in the entrapment solvent. A preferred extraction solvent comprises a supercritical fluid. Also provided are cigarettes and cigarette components comprising extracted tobacco solutes such as flavor compounds, aroma compounds and nicotine. Further, tobacco from which aroma compounds and/or nicotine have been extracted can be used in cigarettes.Type: ApplicationFiled: July 29, 2005Publication date: February 1, 2007Inventors: Tony Howell, Gregory Griscik
