Definitions

  • the invention relates to a ventilated filter cigarette according to Preamble of claim 1.
  • From DE-OS 32 28 950 is a generic ventilated filter cigarette a proportionally volume-activated (i.e. expanded) tobacco blend known, which has a nicotine content of 2-5%.
  • This Cigarette has a low efficiency filter with a filter efficiency of a maximum of 35%.
  • the condensate values according to the Examples are between 7 and 17 mg "tar", i.e. Condensate.
  • From DE-OS 36 38 801 is a ventilated filter cigarette known essentially constant taste per train. This is achieved by using a special filter material, that with increasing steam content of the main stream smoke for ventilation air is becoming increasingly permeable.
  • EP-A2-0 283 672 describes the doping of cigarette tobacco with nicotine and levulinic acid or nicotine levulate disclosed.
  • the Condensate values of the ventilated filter cigarettes made with it should be less than 7 mg "tar”.
  • the object of the invention is to provide an ultra-light filter cigarette in which, compared to the known prior art, the maintenance of an almost constant, high-quality taste per train with overall extremely low condensate and nicotine values and, at the same time, reduction of all undesirable The smoke contents of both the main flow smoke and the secondary flow smoke are guaranteed to a minimum when using conventional, inexpensive equipment materials, in particular without complicated filter technology.
  • the combination according to the invention can, for example all unwanted smoke ingredients both the gas and the particle phase can be reduced to a minimum, with the Flavors and flavors desired by smokers including Surprisingly, nicotine is still in one fully satisfactory dimensions are available to the non-smokers.
  • value level e.g. K ⁇ 1 mg / N ⁇ 0.1 mg
  • subjective: fully satisfactory Flavor volume - may contribute that, again, not predictable an approximately constant amount of "flavor condensate" from the first pull is offered, as shown in Figure 1, in the amount of condensate offered per train versus the number of trains is applied. This is precisely the case with conventional ones Ultralight cigarettes do not exist and like them contribute to lack of acceptance.
  • volume-activated tobacco is characterized by the INCOM process in particular by maintaining the cell structure of the tobacco fibers from what is not to this extent in other known methods given is.
  • the cell structure of several, according to other methods volume-activated tobacco suffers considerably pulled, and associated with it can be significant aroma and Nicotine losses occur, which is not the case with INCOM tobacco the case is.
  • This multiple filter, also multi or combination filter consists of at least two different, possibly filter parts arranged at a distance (hollow chamber filter) from one another or filter sections that consist of different, different filter materials are built and therefore retain different smoke ingredients to different extents and thus also "tastefully" coordinated can be tasted, especially in connection with this positive effect adapted, high degree of ventilation.
  • the tobacco mixture as a whole is preferably inflatable or Undergone expansion process.
  • the volume increases the mixture and gives - based on the initial volume - a corresponding increase in the "filling capacity" of the tobacco mixture.
  • only the lamina portion is undamaged Tobacco containing cell material, expanded or volume-activated, usual film tobacco, if it is added, thus Not. Due to the (mathematical) expansion of the overall mixture expandable lamina tobacco and non-expandable film tobacco the intimately mixed, finely cut tobacco pieces together a both mechanical and thermal treatment exposed.
  • Time-dependent migration is likely to be this way of nicotine from foil tobacco to lamina tobacco respectively from high nicotine-containing lamina tobacco to the lower favors nicotine-containing lamina tobacco, so that a more homogeneous Nicotine distribution in the tobacco blend is achieved.
  • This The procedure is more expensive, but favors the while of smoking the cigarette with the same taste Effect of main stream smoke. But it can only part of the tobacco blend such as the Lamina tobacco the unexpanded portion are subjected to the expansion process the mixture used can be conventional or "technical" tobacco like rib cuts. The latter can be used, for example, to control the taste serve the reactivity of the cigarette according to the invention, as well the addition of known casing and flavor substances, which also contribute to the desired overall taste impression. Ultimately can be added to the casing and / or flavoring Total tobacco mixture or parts thereof before or after Bloating or expansion processes take place. The finished tobacco blend is then in a known manner on conventional cigarette machines including the sophisticated multiple filters proceed to the filter cigarettes according to the invention.
  • the tobacco mixture is otherwise used same manufacturing conditions on the use of film tobacco completely dispensed with, so that here the entire final cigarette tobacco mixture volume activatable. This leaves natural Tobacco of up to 6% by weight nicotine, in particular Cases even use up to 8% by weight nicotine.
  • PAPER double filters
  • ACETAT conventional cellulose acetate fiber filter
  • the tensile resistance of the 12 mm long string-side PAPER filter section was 175 daPa
  • Draw resistance of the 13 mm long ACETAT filter section on the mouth was 15 daPa.
  • the caused by a laser perforation Filter ventilation resulted in a degree of ventilation according to DIN 6565 of 77% additional air.
  • the smoke data of this cigarette A1 (measurements according to DIN-ISO 3402/4387/10315 / 10362-1) are summarized in Table 1.
  • the smoke pH was also measured, according to the method described by Harris et al. (32 nd Tob. Chem. Res. Conf., 1978) method described above.
  • Table 1 also shows the corresponding values for cigarettes A2 and A3, which differ from cigarette A1 only in the filter.
  • a PAPIER / ACETAT double filter with a strand-side PAPIER filter section of 12 mm length and a mouth-side ACETAT filter section of 13 mm length was used, but with different pulling resistances and a different value for the degree of ventilation.
  • Table 2 shows the smoke data for the three cigarettes B1, B2 and B3, which differ from each other in the drawing resistance of the filter sections and the degree of ventilation.
