Definitions

  • the invention provides apparatus for treating prepared tobacco by inserting the tobacco in an enclosure, either as 1oose" tobacco alone or in a temporary container or as a smokers article such as a cigarette, cigarillo or cigar, and applying suction or fluid pressure across the matrix of tobacco so as to result in a flow of fluid therethrough for the purpose of introducing a treating substance to be carried by the flow of fluid into the tobacco.
  • substances to tobacco for use in a pipe or in smoking articles.
  • These substances may be for instance: flavours and casing solutions containing menthol or licorice; burn or ash control substances; various humectants or medicines such as ephedrine or narcotic substances; and psychogenic drugs including canabinol or euphoric agents.
  • All manner of substances, including finely-divided powders, solutions and dispersions, may be infused through or coated upon strands of tobacco by the apparatus of this invention.
  • tobacco is treated by inserting the same in an enclosure, applying a diflerential of fluid pressure across the enclosure so as to result in a flow of fluid through the tobacco, and introducing a treating substance into the flow of fluid so as to be carried into the tobac-
  • the differential of fluid pressure may be obtained by applying suction at a first location of the enclosure, or a greater than atmospheric pressure, e.g. as from a propellent fluid, at a second location of the enclosure, but it is preferred to use both suction and pressure together or successively as it has been found that this results in a particularly thorough permeation of the tobacco matrix by the treating substance.
  • the treating substance may be applied separately to the enclosure, but it is preferred to include the treating substance in the propellant fluid ab initio, or to obtain mixing of, the propellant fluid and the treating substance immediately prior to application to the tobacco in the enclosure.
  • the tobacco may be inserted in the enclosure 'when in a loose condition, e.g. for the treatment of pipe tobacco, or loose tobacco may be temporarily housed in a receiver such as a cartridge or tube from which it is removed after the treatment.
  • the tobacco may also five-eighths inserted into the enclosure when incorporated in a smokers article such as a cigarette, cigarillo, or cigar, which may therefore be treated by the smoker himself, as well as at the factory where they are made.
  • Apparatus for carrying out the invention comprises broadly means for supporting the tobacco in an enclosure, means for applying a differential of fluid pressure across said enclosure so as to result in flow of fluid through the tobacco, and means for introducing a treating substance into the flow of fluid, so as to be carried into the tobacco.
  • the apparatus may have a body in which the enclosure is housed, a casing being slidable sealingly on said body, in the manner of a piston and associated cylinder, and defining an internal space which communicates with the enclosure.
  • the apparatus may include reservoir means containing the treating substance under pressure, and means for controlling flow of said treating substance from the reservoir means to the enclosure.
  • means for applying suction at one location of the enclosure there are provided means for applying suction at one location of the enclosure, and other means for introducing both propellant fluid and the treating substance at another location of the enclosure.
  • means for applying suction at one location of the enclosure and other means for introducing both propellant fluid and the treating substance at another location of the enclosure.
  • reservoir means for the propellant fluid there may be provided, reservoir means for the treating substance,
  • the reservoirs and preferably also the mixing and control valve, constitute an assembly which is removable and replaceable as a whole when re-charging is required.
  • the treating substance may be in the form of liquid or gas adapted to carry dissolved or dispersed substances through the tobacco matrix and leaving a coating thereon or impregnation therein.
  • a single cigarette may be treated by placing it within a rigid tube, applying suction to one end of the tube, for instance by extending the tube by movement of a plunger or sleeve to create a vacuum at one end of the cigarette and simultaneously or shortly thereafier propelling treatment substance through the cigarette from the other end by blowing a mixture of Freon gas and menthol for instance from an aerosol can into the tobacco rod.
  • This treatment can further be applied to a group of articles simultaneously, such as a pack of 20 cigarettes or cigarillos; or
