Definitions

  • the invention relates to a cigarette paper tube with a filter and tobacco room, for making a cigarette can be filled with tobacco.
  • cigarette paper tubes are generally known (see document DE 4206509 A) and available in the stores. You will be in touch with loose or also prefabricated tobacco rod or cartridge Homemade cigarettes offered.
  • cigarette paper tubes represent filters and Tobacco intake room a constant, i.e. unchangeable size
  • the present invention is the Task based on cigarette paper tubes of the aforementioned Provide type that is variable in terms of the filter are, with the simplest manufacturing technology Means.
  • the cigarette paper tube according to the invention is thus characterized by a filter which consists of at least two filter pieces, the inner filter piece adjacent to the tobacco receiving space being encased by cigarette paper, while the outer filter piece has a diameter which corresponds approximately to the diameter of the inner filter piece including cigarette paper wrapping , so that the outer filter piece can be held by a mouthpiece covering paper on the inner filter piece covered with cigarette paper without forming wrinkles on the mouthpiece covering paper.
  • the two filter pieces allow both a variation of the filter length and a variation of the physical and / or chemical properties of the filter, without this being associated with a greater manufacturing outlay in comparison to conventional filter cigarette paper tube manufacture.
  • the outer filter piece is preferably part of a so-called insert filter, as is used in the production of conventional cigarettes.
  • the insert filter is inserted between two separate cigarette paper tubes, each with an inner filter piece, and is cut in half after being wrapped with tip paper.
  • the inner filter pieces are also part of a so-called double filter, as used to manufacture conventional cigarette paper tubes with filters.
  • the length can be adjust the filter of each cigarette paper tube, without affecting the length of the tobacco room becomes. This measure can also be extremely simple The smoking behavior of the cigarette paper tube filled with tobacco vary.
  • the two filter pieces can each be the same or be different from each other.
  • a filter piece e.g. an acetate carbon filter and the other filter piece is an acetate or crepe filter.
  • the tip of the tip is to add outside air preferably highly porous, in particular micro-lasered, the Filling of the outer filter piece also highly porous, e.g. is micro-lasered, so that in the area of the outer filter piece a predetermined amount of outside or secondary air can be drawn in is.
  • This allows the well-known Achieve effects of adding cool outside air.
  • the mouthpiece covering paper is to promote the effect at least in the area of the outer filter piece only partially, in particular along the axial and / or over the Extending circumferentially and axially spaced apart Stripes glued to the outer filter piece. Point-by-point bonding is also conceivable.
  • a sufficiently large or highly porous perforated area is present to suffice in hot smoke to be able to mix in cool outside air.
  • the two filter pieces are preferably in the axial direction close together; alternatively, they can also be axially apart be spaced to form a so-called filter chamber.
  • the tip paper can be separately perforated so that in this area with everyone Sufficiently cool outside air can be mixed in with the hot smoke is, whereby not only a cooling of the smoke, but a dilution of the same is also obtained.
  • the double or multiple filter is preferably set so that despite the relatively short tobacco and smoking behavior that of a conventional factory cigarette equivalent.
  • the tobacco filling is preferably part of one prefabricated tobacco rod through an outer wrapper is held together in a dimensionally stable manner.
  • the tobacco rod has one Diameter, which is only slightly smaller than that Inner diameter of the tobacco-receiving space of the cigarette paper tube.
  • the wrapping of the tobacco rod can either be highly porous be so that it is not outside the cigarette paper tube is smokable; alternatively, the tobacco rod can also be processed according to Art a smokable cigarette. insofar there is no limit to the possible variations.
  • the diameter is of the outer filter piece about 2/10 mm larger than the outer one Diameter of the inner filter piece covered with cigarette paper. Then it is guaranteed that the impact from outer and inner filter piece with mouthpiece covering paper this does not wrinkle in the area of the outer filter piece.
  • the preferred tobacco filling mentioned above is related with the multiple filter especially set so that under Use of the cigarette paper tube according to the invention, for example as many smoke moves can be made as with one conventional factory cigarette.
  • the outer and inner filter piece yet another filter piece be used, which is also part of a so-called insertion filter is.
  • This intermediate filter piece is preferably a Perforated zone of the mouthpiece covering paper assigned without adhesive.
  • the intermediate filter piece is dimensioned that a gap between the tip paper and outer peripheral surface of the intermediate filter piece arises, in particular an annular space.
  • the minimum distance between the tip paper and the outer peripheral surface the intermediate filter piece is about 30 ⁇ . Should be 40 ⁇ Distance between tip paper and outer peripheral surface of the intermediate filter piece.
  • the outer Filter piece in a constriction extending over the circumference be provided to the space mentioned define.
  • the last two embodiments mentioned are characterized by an extremely low dispersion of the degree of ventilation compared to known filter designs out. Above all, the so-called interference layer effects as they avoided with conventional filter designs, at least significantly reduced. It can be done this way a largely constant degree of filter ventilation to reach.
  • the inner filter piece can be formed from a smoke-impermeable material with at least one axially extending smoke channel.
  • the inner filter piece therefore forms a hollow choke.
  • the inner and outer filter pieces are preferably spaced apart from one another to form a so-called filter chamber into which the aforementioned smoke channel opens.
  • the wrapping or the tip paper is breathable in the area of the filter chamber.
  • the pressure drop in the mouthpiece can be adjusted particularly well, for example at a smoke flow rate of 17.5 cm 3 / s per 40-200 mm water column. Despite this drop in pressure, it is ensured that no large quantities of flavors are lost through the passage of smoke through the mouthpiece.
  • the mouthpiece is easy to manufacture in the manner described: it is just as suitable for mass production as the embodiments described above. If a single smoke duct is used, its inside diameter can be between 0.5 and 1.5 mm, preferably between 0.8 and 1.0 mm.
  • the inner filter piece can be used as a mineral filter be trained to filter out toxic compounds in smoke, without the smoker with the appropriate filter piece came into contact.
  • the outer filter piece closes the inner filter piece from the outside.
  • 1 shows an industrially prefabricated cigarette paper tube with a duplo filter consisting of an inner, immediately adjacent to the tobacco receiving space 11 filter piece 12 and an outer filter piece 13, which by a Mouthpiece covering paper 14 in a fixed assignment to the inner filter piece 12 is held.
  • 2 is the inner Filter piece 12 wrapped in cigarette paper 15.
  • the outer Diameter of the outer filter piece 13 corresponds to the outer one Diameter of the inner filter piece 12 including the cigarette paper wrapper 15, so that the tip paper 14 crease-free also struck around the outer filter piece 13 can be.
  • the tip paper is in conventional Way over the inner, the tobacco receiving space 11 delimiting Front of the inner filter piece 12 in front.
  • the tip paper in the Area of the outer filter piece 13 highly porous e.g. with a Perforation 16 extending over the circumference be dealing with a corresponding highly porous area the covering of the outer filter piece 13 covers.
  • This Envelope is no longer shown in the figures since it is generally known.
  • Cigarette paper tube also in association with an industrial prefabricated dimensionally stable tobacco portion in shape a rod-like tobacco cartridge that is outside the cigarette paper tube 10 either smokable or non-smokable is, in any case, made of completely smokable material consists. Is an additional one on one end of the tobacco cartridge If the filter piece is attached, the filter variation described can be increase accordingly. You get at the assembled cigarette in this way a kind of Triple filter.
  • the filter piece attached to the tobacco cartridge is preferably relatively short, e.g. only 5 mm long.
  • Such a trained tobacco cartridge can be part of a so-called duplo tobacco portion be that has a total length that the double the length of the tobacco storage space associated with one Cigarette paper tube corresponds.
  • the Duplo tobacco serving contains either a double filter in the middle, which before use is cut apart in the middle, so that one two tobacco cartridges with a filter piece attached to the front receives.
  • the Duplo tobacco portion can also be used in each case have a filter piece at the end.
  • the making of a Cigarette then takes place by postponing an assigned one Cigarette paper tube on both ends of the Duplo tobacco serving and then separating them in the area of the joint of the two cigarette paper tubes pushed on at the front.
  • This Duplo portion of tobacco is also suitable also in association with conventional cigarette paper tubes simple filter piece, which is preferably a little shorter can be dimensioned as the filter pieces more comparable conventional Filterhülsen.
  • the ventilation zone is if such is provided, advantageously in the area of the filter pieces attached to the tobacco cartridge.
  • the attached filter pieces can e.g. with retention-specific Fabrics, especially with activated carbon and / or silica gel be offset. Also taste-influencing agents be provided, such as menthol or the like.
  • These active substances can e.g. are located in so-called microcapsules that are caused by light finger pressure can be broken from the outside, whereby the finger pressure is so light that the tip paper or cigarette paper is not damaged or wrinkled becomes.
  • the aforementioned microcapsules have the advantage that the active ingredients are encapsulated until use and only take effect after breaking open. An early one This prevents volatilization of the active ingredients.
  • the inner filter piece can also 12 according to the embodiment according to FIGS. 1 and 2 be provided with such microcapsules. The above Description shows very clearly that the invention Cigarette paper tube by a high degree of Degrees of freedom.
