Definitions

  • the invention relates to a method according to the preamble of claim 1, a cigarette end piece, in particular a cigarette filter, for carrying out the method, and a use of this method.
  • a filter chamber is only filled with such an active material with only 5% of its volume, only a very small, narrow segment of the latter is aromatized or filtered over the entire flow cross-section of the smoke gas stream sucked into his mouth, and this under certain circumstances every time the smoker pulls on such a cigarette in different ways, which is extremely undesirable in relation to the taste sensation of a smoker.
  • Chambers which are only partially filled with free-flowing active material also cause the cigarette filters provided with them to be further processed, i.e. when they are transported and connected to the tobacco part to form the filter cigarettes, when used in certain further processing plants, there is a risk of collapse due to insufficient stability of these partially filled chambers, which can give rise to unpleasant disruptions in the further processing of such cigarette filters.
  • cigarette filters with chambers only partially filled with free-flowing active material have the further disadvantage that the tobacco smoke takes the path of the lowest flow resistance when flowing through these only partially filled chambers, i.e. flows through the unfilled part of such a chamber instead of through the granular active material, so that the effect of the latter cannot be optimally used.
  • the object of the present invention is above all to create a method which does not have the disadvantages of the previous methods mentioned above, ie which has a very precise setting of the degree of aromatization and / or filtering of a tobacco smoke flowing through enables, and / or forms an extremely stable, not collapse-prone chamber, and causes an optimal flow and utilization of the granular active material located in such a chamber.
  • the invention further relates to a cigarette end piece according to claim 11.
  • Appropriate further developments of the cigarette end piece according to the invention are the subject of claims 12 and 13.
  • the invention also relates to a use of the method according to the invention as claimed in claim 14.
  • a cigarette Z (shown on an enlarged scale for better visibility) is provided with a tobacco part T which is connected to a chamber filter via a so-called tipping paper strip 4.
  • the chamber filter consists of the two plugs 5 and 6, which are connected in a known manner to an enveloping strip 7 to form a chamber 1 located between them.
  • this free-flowing granulate mixture to be filled into these filter chambers can easily be produced very precisely with this previously determined mixing ratio of activated carbon 2 and inactive charcoal 3 and with an extremely even distribution of the two mixture components among one another and e.g. be introduced into the chambers 4 of a cigarette filter unit to be manufactured by means of a device known from CH-A-604 574.
  • the amount of free-flowing activated carbon 2 present in these chambers 1 is thereby extremely precise, so that no relevant difference in the amount of active material 2 filled in or the filtering effect can be determined between different chambers 1 in this way.
  • the extremely uniform distribution of the activated carbon components 2 over the entire chamber volume also results in an extremely even inflow all of the activated carbon components 2 located in this chamber 1 and thereby in turn achieving an optimal utilization of their adsorption effect on the flowing tobacco smoke.
  • the best possible filling of the individual chambers 1 with the mixture of active and inactive free-flowing material 2, 3 which is active against the flowing tobacco smoke should be sought between different cigarette filter units, although in practice depending on the system used for filling this mixture into the individual chambers 1, a maximum degree of chamber filling of only about 95 to 97% of the chamber volume can be achieved, which, however, still has very significant advantages over the methods known hitherto when using much smaller volumes of active material per chamber than the chamber volume causes.
