Definitions

  • Examples of a filter mouthpiece which provides for partial localization of exit smoke at the periphery are certain embodiments disclosed by Kiefer et al. in U.S. 3,768,489 and by Labbe in 3,685,523. Miller, U.S. 3,062,219, discloses an offset opening to partially localize the exit smoke at one side of the filter tip.
  • the invention is a mouthpiece or exit tip baffle for a filtered cigaret or cigaret holder having a filter, which serves to focus or collimate the exit smoke to a narrow pattern. This is done not merely with a central opening, but with a 3-dimensional funneling mouthpiece. Such a pattern improves the subjective perception of cigarets which have a low "tar" delivery as a result of filtration, usually with air dilution.
  • the smoke from cigaret rod 11 passes through a filter 12 and is collimated by plastic mouthpiece 13 to exit through orifice 14, diameter 0.44 cm, in a stream which is shown schematically as 15 based on observations made during smoking by an automated smoking machine by using high speed cinematography.
  • Figure 2 shows a similar mouthpiece 16 having a very much smaller orifice 17, 0.16 cm in diameter, which produces a smoke pattern 18 converging to a focus and diverging thereafter.
  • Figure 3 illustrates the exit pattern 19 diverging directly from an unmodified filter of a conventional 0.78 cm diameter.
  • the pattern 20 is kept nearly constant by hollow mouthpiece 22.
  • Figure 5 shows a filter cigaret equipped with an alternative mouthpiece 23 having cone-shaped baffle 24 (supported in its central location by fins or prongs-not shown) and giving an exit smoke pattern 21 which is likewise cone-shaped.
  • the present invention employs a different approach: a reinforcement of the impact perceived by the smoker through addition of a mouthpiece baffle having such a configuration that the issuing smoke is confined to a narrow stream. This configuration is not simply an orifice alone, but an orifice as a termination of a funnel-shaped mouthpiece shaped to focus the smoke stream or cause it to converge.
  • the convergence of the smoke may be toward a central point or into another defined exit pattern such as a cone.
  • the result is enhancement of the subjective effect of the smoke which may have been attenuated by dilution or filtration.
  • the effect is particularly noticeable with a centralized delivery ( Figures 1 and 2).
