Definitions

  • the invention relates to a ventilated filter cigarette, according to the preamble of patent claim 1.
  • EP 0 875 160 A1 describes a ventilated filter cigarette which has a filter part which has a coaxial filter core and a filter jacket which surrounds the coaxial filter core.
  • ventilation holes for introducing ventilation air into the jacket are provided.
  • the design of the material specifications and the dimensioning of the individual elements of the tobacco rod and the filter are designed so that when the smoker covers the ventilation holes, the smoke is essentially passed through the filter jacket in the manner of a changeover valve, while in the case of uncovered ventilation holes, the smoke mainly flows through the filter core of the coaxial filter part.
  • the aim of this development is to be able to quantitatively control the smoke yield with different consumer behavior, for example to minimize an increase in the condensate values.
  • this smoke is an aerosol, i.e. a mixture of air and liquid droplets. These can be of significantly different sizes, but this is not recognizable to the human eye.
  • the taste assessment of tobacco smoke by the consumer i.e. the aroma quality or the intensity of the taste impression, is measured by the smoke flow rate and by the droplet size and distribution, which are measured with the help of mobility analyzers or by selective collection and sorting by particle weight or particle size can be influenced.
  • the object of the invention is to provide a filter construction with which the distribution of the droplet size supplied to the smoker and the flow rate of the smoke can be controlled.
  • a filter cigarette with the features of claim 1 is used to solve this problem.
  • the condensate and nicotine values are set over a very short distance in the filter section facing the tobacco rod.
  • the filter diameter used by the main flow smoke is reduced, which accelerates the smoke in this area to about three times the speed.
  • Such a filter construction leads to a significant increase in aroma compared to a conventional filter with low condensate values. It has been shown that both the smoke composition and the average droplet size are influenced by the change in the flow rate and that the aroma impression and thus the taste can be increased at significantly higher flow rates.
  • the drawing shows a schematic representation of a filter cigarette with a tobacco rod 6 and a filter 7, which are arranged in a colinear manner one behind the other and connected to one another by a wrapping paper 8.
  • the tobacco rod is usually between 55 and 75 mm long, while the length of the filter is 21 to 27 mm.
  • the wrapping paper 8 covers the interface between the filter 7 and the tobacco rod 6 about 2 to 5 mm.
  • Suitable filter materials for the filter 7 are sheet-like, fibrous or granular filter materials, such as cellulose, cellulose esters, preferably cellulose acetate, meltblown filters, e.g. manufactured according to WO97 / 33026, airlaid filter material e.g. manufactured according to US 4,375,447, additive filter materials, tobacco, other easily decomposable filter materials or thermoplastic filter fibers.
  • Additives can be added by sprinkling or spraying onto the filter materials, e.g. Fibers, or by direct injection into the material strand.
  • Possible additives for the filter material are: flavoring agents, acids or bases in suspended or dissolved form, or selectively acting adsorbents such as activated carbon or SiO 2.
  • the pH values of the particle spectra can be influenced by adding acids or bases.
  • additives with a selective retention effect are organic acids and their salts, metals and metal oxides, nitrogen components, ion exchange systems (e.g. zeolites), alcohols, polyphenols and porphyrin derivatives.
  • the tobacco rod 6 is initially connected to a tobacco rod-side filter part 3 in the form of a so-called monofilter, to which a mouth-side filter part 4 in the form of a coaxial filter is connected at the end facing away from the tobacco rod 6.
  • the monofilter forming the tobacco rod-side filter part 3 is made of one of the above-mentioned filter materials, preferably of cellulose acetate with a single titer of 2.50 den and a total titer of 35,000 den and optionally mixed with activated carbon.
  • the outside diameter of the filter part 3 on the tobacco rod side is 7.8 mm, and its length is 13.0 mm.
  • the pressure drop in the tobacco rod-side filter part 3 should be, for example, 30 to 50 mmWS, preferably 42 mmWS.
  • the wrapping paper 8 is provided with ventilation holes 5 as ventilation means, which are arranged in the form of 1 to 3 rows, preferably 2 rows of holes, around the filter 7, in the area of the mouth-end filter part 4 is the wrapping paper 8 however completely impermeable.
  • ventilation holes 5 ventilation air m is sucked into the filter 7, which leads to the fact that the condensate and nicotine values of the main flow smoke supplied from the tobacco rod 6 are reduced in the area of the filter part 3 on the tobacco rod side.
  • ventilation holes are to be produced, for example mechanically or electrostatically or by means of laser perforations.
  • Other also known ventilation means are cannulas or material savings.
  • the mouth-side filter part 4 forming a coaxial filter has a core 1 and a jacket 2 coaxially surrounding the core 1.
  • the pressure drop of the core can be between 10 and 50 mmWS.
  • the jacket is designed so that its pressure drop is at least a factor of 2 greater than that of the core.
  • the coat can also be smoke-tight.
  • the core 1 had a diameter of 4.0 mm and a length of 8.0 mm. In one embodiment it was made from cellulose acetate with a single titer of 6.0 denier and a total titer of 17,000 denier. The tensile resistance or pressure drop of core 1 was 20 mmWS.
  • the jacket 2 coaxially surrounding the core 1 had an inner diameter of 4.0 mm and an outer diameter of 7.8 mm with a length of likewise 8.0 mm.
  • the coaxial filter had a length of 8.0 mm with a diameter of 7.8 mm.
  • Possible ranges for other embodiments are: a single titer in the range from 3.0 to 8.0 den, preferably 6.0 den and a total titer in the range from 15,000 to 50,000 den, preferably 17,000 den, for the core.
  • the range for the tobacco rod-side single titer is 1.5 to 5 den and for the total titer 15000 to 60,000 den.
