Definitions

  • the invention relates to a ventilated filter cigarette according to the preamble of patent claim 1.
  • a ventilated filter cigarette with a proportionally volume-activated (i.e. expanded) tobacco mixture which has a nicotine content of 2-5%.
  • This cigarette has a low efficiency filter with a maximum filter efficiency of 35%.
  • the condensate values according to the examples are between 7 and 17 mg "tar", i.e. Condensate.
  • EP-A2-0 283 672 discloses doping cigarette tobacco with nicotine and levulinic acid or nicotine levulate.
  • the condensate values of the ventilated filter cigarettes manufactured with it should be below 7 mg "tar”.
  • ventilated filter cigarettes are known or available on the market at the time of registration, the condensate (K) and nicotine (N) values of which are around or below 1 mg K and 0.1 mg N.
  • the Cigarette NOW from REYNOLDS / USA with a condensate value of ⁇ 0.5 mg, furthermore the Cigarette DUNHILL ULTIMATE LIGHTS from Rothmans with a value specification "Less than 1 mg TAR, 0.1 mg NICOTINE".
  • Such cigarettes are judged by most consumers to be in need of taste improvement, which can be derived on the one hand from the comparatively small market share of such cigarettes and on the other hand is confirmed by internal smoking tests.
  • the object of the invention is to create an ultra-light filter cigarette, in which, compared to the known prior art, the maintenance of a nearly constant, qualitatively good taste offer per train with overall extremely low condensate and nicotine values and simultaneous reduction of all undesirable smoke constituents of both the main flow smoke and the secondary flow smoke to a minimum, using conventional, inexpensive equipment materials, in particular without complicated filter technology.
  • volume-activated tobacco by the INCOM process is characterized in particular by the preservation of the cell structure of the tobacco fibers, which is not the case with other known processes.
  • the cell structure of a number of tobacco products that are volume-activated by other methods is considerably affected, and in connection with this, in some cases considerable loss of aroma and nicotine can occur, which is not the case with INCOM tobacco products.
  • Relevant flavorings, nicotine and secondary alkaloids are at most "unlocked", i.e. they can be transferred particularly easily from even small amounts of air or mainstream smoke.
  • this unexpectedly high taste volume at the lowest values could be promoted by using the multi-filter, which is part of the invention and is highly retentive, the retention performance or efficiency of which is determined by the total amount of substance (condensate and nicotine) retained in the filter, based on the inflowing amount of substance.
  • This multiple filter also known as a multi-filter or combi-filter, consists of at least two different filter parts or filter sections, which may be spaced apart (hollow chamber filter) and which are made up of different filter materials that differ from one another and therefore retard different smoke constituents to different extents. kidneys and thus also "taste" can be coordinated with one another, especially in connection with a high degree of ventilation adapted to this taste-positive effect.
  • This desired effect can be achieved by using commercially available or certain sidestream smoke-reducing cigarette papers - for example by cigarette papers according to the patent documents DE 38 02 645 and DE 38 02 646 of the applicant - are strengthened, also by correspondingly smaller dimensioned cigarette formats.
  • the tobacco mixture as a whole is preferably subjected to the blowing or expansion process.
  • the volume of the mixture increases and, based on the initial volume, results in a corresponding increase in the "filling capacity" of the tobacco mixture.
  • only the lamina portion or tobacco containing undamaged cell material is inflated or volume-activated, so conventional film tobacco, if added, is not. Due to the (arithmetical) expansion of the entire mixture of expandable lamina tobacco and non-expandable film tobacco, the intimately mixed, finely cut tobacco parts are exposed to both mechanical and thermal treatment.
  • the time-dependent migration of the nicotine from the film tobacco to the lamina tobacco or from the high-nicotine-containing lamina tobacco to the less nicotine-containing lamina tobacco is presumably favored, so that a more homogeneous nicotine distribution in the tobacco mixture is achieved.
  • this procedure is more expensive, it favors the taste effect of the main stream smoke that remains constant while the cigarette is being smoked.
  • only a part of the tobacco mixture, such as the lamina tobacco can be subjected to the expansion process.
  • the unexpanded portion of the mixture used can consist of conventional or "technical" tobaccos such as rib cuts.
  • the latter can be used, for example, to control the taste of the reactivity of the cigarette according to the invention, as can the addition of casing and flavoring substances known per se also contribute to the desired overall taste impression.
  • the casing and / or flavoring substances can be added to the overall tobacco mixture or to parts thereof before or after the blowing or expansion process.
  • the finished tobacco mixture is then processed in a known manner on conventional cigarette machines, including the multiple filters according to the claims, to form the filter cigarettes according to the invention.
  • the film tobacco is completely dispensed with under otherwise identical production conditions, so that the entire final cigarette tobacco mixture can be volume-activated.
  • Natural tobacco of up to 6% by weight of nicotine is used, in special cases even up to 8% by weight of nicotine.
  • cigarette strands were produced (diameter 7.9 mm, length 59 mm) a tobacco operating weight of 460 mg and a total weight including cigarette paper of 500 mg.

  • a PAPIER / ACETAT double filter with a string-side PAPIER filter section of 12 mm length and a mouth-side ACETAT filter section of 13 mm length was used, but with different tensile resistances and a different value for the degree of ventilation.

Abstract

Une cigarette à filtre aérée comprend un filtre multiple ayant une plus grande capacité globale de rétention, pourvu de perforations d'aération dans différentes sections. La cigarette à filtre aérée contient un mélange de tabac expansé à haute teneur en nicotine. Le mélange de tabac contient en tant qu'éléments constitutifs des limbes de tabac avec une teneur en nicotine comprise entre 1,0 % et 8 % et/ou des feuilles de tabac avec une teneur en nicotine comprise entre 5 % et 10 %, ainsi qu'un acidulant. La teneur en nicotine du mélange de tabac est comprise entre 2,5 % et 5 %. La résistance au tirage du filtre multiple est plus haute du côté du faisceau que du côté de la bouche et le degré d'aération est compris entre 50 % et 95 % d'air ajouté. Le courant principal de fumée a de préférence un goût de type 'american blend' qui reste approximativement constant avec chaque bouffée. La valeur de pH de la fumée est comprise dans une plage entre 6,0 et 7,5. Tout en donnant de bons résultats sensoriels, les valeurs de condensat et de nicotine sont, respectivement, inférieures à 1 mg/cigarette et à 0,1 mg/cigarette et, dans certains cas particuliers, inférieures à 3 mg/cigarette et à 0,6 mg/cigarette.
