  • Patent number: 11700877
    Abstract: 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: Grant

  • Patent number: 7518123
    Abstract: 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.

  • Publication number: 20070023058
    Abstract: 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.
