Definitions

  • BACKGROUND Traditional cigarettes are smoked by lighting an end of a wrapped tobacco rod and drawing air predominately through the lit end by suction at a mouthpiece end of the cigarette. Traditional cigarettes deliver smoke as a result of combustion, during which tobacco is combusted at temperatures that typically exceed 800 °C during a puff. The heat of combustion releases various gaseous combustion products and distillates from the tobacco. As these gaseous products are drawn through the cigarette, they cool and condense to form an aerosol, which provides the flavors and aromas associated with smoking. [0002] Traditional cigarettes produce sidestream smoke during smoldering between puffs. Once lit, they normally are fully consumed or discarded. Relighting a traditional cigarette is possible, but is not desirable for subjunctive reasons including flavor, taste and odor.
  • An alternative to the more traditional cigarette is the electrically heated cigarette used in electrical smoking systems.
  • electrical smoking systems significantly reduce sidestream smoke, and also permit smokers to suspend and reinitiate smoking as desired.
  • Exemplary electrical smoking systems are disclosed in commonly-assigned U.S. Patents Nos. 6,026,820; 5,988,176; 5,915,387; 5,692,526; 5,692,525; 5,666,976; 5,499,636; and 5,388,594, each of which is hereby incorporated by reference in its entirety.
  • Electrical smoking systems include an electrically powered lighter and an electrically heated cigarette, which is constructed to cooperate with the lighter.
  • electrical smoking systems be capable of delivering smoke in a manner similar to the smoker's experiences with traditional cigarettes, such as by providing an immediacy response (smoke delivery occurring immediately upon draw), a desired level of delivery (that correlates with FTC tar level), a desired resistance to draw (RTD), as well as puff-to-puff and cigarette-to-cigarette consistency.
  • Nolatile flavorings have been incorporated in traditional cigarettes to add flavors and aromas to mainstream and sidestream tobacco smoke. See, for example, U.S. Patents ⁇ os. 3,006,347; 3,236,244; 3,344,796; 3,426,011; 3,972,335; 4,715,390; 5,137,034; 5,144,964; and 6,325,859, and commonly- owned International Publication No. WO 01/80671.
  • the added flavorings are desirably volatilized when the cigarette is smoked.
  • volatile flavorings tend to migrate in the cigarette to other components and possibly through the entire cigarette. Nolatile flavorings can be lost from cigarettes during storage and distribution at ordinary conditions prior to smoking of the cigarettes.
  • Flavorings that have been incorporated in traditional cigarettes also can chemically and/or physically deteriorate by contacting and/or reacting with other components of the cigarette, as well as with the environment.
  • activated carbon has been incorporated in traditional cigarettes to remove gas- phase constituents from mainstream smoke.

  • An electrically heated cigarette includes one or more sorbents and at least one flavoring for affecting flavor, taste, and/or aroma of tobacco smoke.

Abstract

L'invention concerne des cigarettes chauffées électriquement qui sont utilisées dans un système électrique servant à fumer et qui comportent un additif libérateur d'arôme ainsi qu'un agent de sorption permettant d'éliminer efficacement un ou plusieurs constituents en phase gazeuse de la fumée de tabac du courant principal. L'additif libérateur d'arôme comprend au moins un arôme. Cet arôme est libéré dans la cigarette lorsque l'additif libérateur d'arôme atteint au moins une température minimale pendant que la cigarette est fumée. L'additif libérateur d'arôme peut se présenter sous plusieurs formes telles que des perles, des pellicules ou des composés d'inclusion. Cette invention se rapporte en outre aux systèmes électriques servant à fumer qui contiennent lesdites cigarettes chauffées électriquement, à des procédés de production de ces cigarettes, ainsi qu'à des procédés pour fumer lesdites cigarettes.
