Definitions

  • the invention relates to a cigarette paper tube with filter and tobacco receiving space which can be filled with tobacco for the self-production of a cigarette.
  • Such cigarette paper tubes are generally known and commercially available. They are offered in connection with loose or rod-shaped or cartridge-like tobacco for the self-production of cigarettes. However, the known cigarette paper tubes provide a constant, i.e. unchangeable size. Accordingly, the present invention seeks to provide cigarette paper tubes of the type mentioned, which are variable in terms of the filter, with the simplest manufacturing technology.
  • 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 enveloped 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 on the inner filter piece wrapped with cigarette paper by a mouthpiece covering paper without forming wrinkles on the mouthpiece covering paper.
  • the two filter pieces allow both a variation in the filter length and a variation in 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 of the filter of each cigarette paper tube can be adjusted without influencing the length of the tobacco receiving space. This measure also allows the smoking behavior of the cigarette paper tube filled with tobacco to be varied in an extremely simple manner.
  • the two filter pieces can each be configured identically or differently from one another.
  • the one filter piece e.g. an acetate carbon filter and the other filter piece an acetate or crepe filter.
  • the tip paper is preferably highly porous, in particular micro-lasered
  • the Filling of the outer filter piece is also highly porous, for example micro-lasered, so that a predetermined amount of outside or secondary air can be drawn in in the area of the outer filter piece.
  • the tip of the tip paper is only glued to the covering of the outer filter piece, at least in the area of the outer filter piece, in particular along longitudinally axial and / or axially spaced and axially spaced strips. Point-by-point bonding is also conceivable. In any case, it must be ensured that there is a sufficiently large, highly porous or perforated area in order to be able to mix in sufficiently cool outside air in the hot smoke.
  • the two filter pieces are preferably close together in the axial direction; alternatively, they can also be axially spaced from one another to form a so-called filter chamber.
  • the tip paper can be perforated separately, so that in each area the cool smoke can be mixed with cool outside air each time, which not only cools the smoke, but also dilutes it.
  • the double or multiple filter is preferably set so that the draft and smoke behavior corresponds to that of a conventional factory cigarette, despite the relatively short tobacco receiving space.
  • the tobacco filling is preferably part of a prefabricated tobacco rod which is held together in a dimensionally stable manner by an outer covering.
  • the tobacco rod has a diameter which is only slightly smaller than the inner diameter of the tobacco receiving space of the cigarette paper tube.
  • the wrapping of the tobacco rod can either be highly porous so that it cannot be smoked outside the cigarette paper tube; alternatively, the tobacco rod can also be processed according to Art a smokable cigarette. In this respect there is no restriction on the possible variations.
  • the diameter of the outer filter piece is approximately 2/10 mm larger than the outer diameter of the inner filter piece covered with cigarette paper. Then it is ensured that when the outer and inner filter pieces are wrapped with tip paper, this does not crease in the area of the outer filter piece.
  • the preferred tobacco filling mentioned above is set in connection with the multiple filter so that using the cigarette paper tube according to the invention approximately as many smoke passes can be made as with a conventional factory cigarette.
  • a further filter piece can be inserted between the outer and inner filter piece, which is also part of a so-called insert filter.
  • This intermediate filter piece is preferably associated with an adhesive-free perforated zone of the tip coating paper.
  • the intermediate filter piece is dimensioned such that an intermediate space is created between the tip paper and the outer peripheral surface of the intermediate filter piece, in particular an annular intermediate space.
  • the minimum distance between the tip paper and the outer peripheral surface of the intermediate filter piece is about 30 ⁇ .
  • the distance between the tip paper and the outer circumferential surface of the intermediate filter piece should not exceed 40 ⁇ .
  • the outer filter piece in the case of a Duplo filter design, can be provided in a constriction extending over the circumference in order to define the above-mentioned space.
  • the two last-mentioned embodiments are distinguished by an extremely low spread of the degree of ventilation in comparison with known filter designs. Above all, the so-called interference layer effects, as they occur in conventional filter designs, are avoided, or at least considerably reduced. In this way, a largely constant degree of filter ventilation can be achieved.
  • 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, e.g. at a smoke flow rate of 17.5 cm3 / s on 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 designed as a mineral filter in order to filter out toxic compounds in the smoke without the smoker coming into contact with the corresponding filter piece.
  • the outer filter piece closes the inner filter piece from the outside.
  • Fig. 1 shows an industrially prefabricated cigarette paper tube with a Duplo filter, consisting of an inner filter piece 12 directly adjacent to the tobacco receiving space 11 and an outer filter piece 13 which is held in fixed association with the inner filter piece 12 by a tip paper 14. 2, the inner filter piece 12 is enveloped by the cigarette paper 15. The outer diameter of the outer filter piece 13 corresponds to the outer diameter of the inner filter piece 12 together with the cigarette paper wrapper 15, so that the tip paper 14 can also be folded around the outer filter piece 13 without creases.
  • the mouthpiece covering paper protrudes in a conventional manner over the inner end face of the inner filter piece 12 which delimits the tobacco receiving space 11.
  • the mouthpiece covering paper can be highly porous in the area of the outer filter piece 13, for example provided with a perforation 16 which extends over the circumference and coincides with a corresponding highly porous area of the envelope of the outer filter piece 13.
  • a perforation 16 which extends over the circumference and coincides with a corresponding highly porous area of the envelope of the outer filter piece 13.
  • the cigarette paper tube described is also suitable in association with an industrially prefabricated, dimensionally stable tobacco portion in the form of a rod-like tobacco cartridge, which is either smokable or non-smokable outside the cigarette paper tube 10, and in any case consists of completely smokable material. If an additional filter piece is attached to one end of the tobacco cartridge, the filter variation described can be increased in a corresponding manner. In this way, a kind of triple filter is obtained with the assembled cigarette.
  • the filter piece attached to the tobacco cartridge is preferably relatively short, for example only 5 mm long.
  • a tobacco cartridge designed in this way can be part of a so-called duplo tobacco portion, which overall has a length that corresponds to twice the length of the tobacco receiving space of an assigned cigarette paper tube.
  • the Duplo tobacco portion either contains a double filter in the middle, which is cut apart in the middle before use, so that two tobacco cartridges with a filter piece attached to the front are obtained.
  • the Duplo tobacco portion can also have a filter piece at each end.
  • a cigarette is then produced by pushing an assigned cigarette paper tube onto both ends of the Duplo tobacco portion and then separating it in the region of the joint of the two cigarette paper tubes pushed on at the end.
  • this Duplo tobacco portion is also suitable in association with conventional cigarette paper tubes with a simple filter piece, which can preferably be dimensioned somewhat shorter than the filter pieces of comparable conventional filter tubes.
  • the ventilation zone advantageously lies in the area of the filter pieces attached to the tobacco cartridge.
  • the attached filter pieces can e.g. with retention-specific substances, in particular with activated carbon and / or silica gel. It is also possible to provide taste-influencing active substances, such as menthol or the like. These active substances can e.g. are located in so-called microcapsules, which can be broken open from the outside by light finger pressure, the finger pressure being so light that the tip paper or cigarette paper is not damaged or crumpled as a result.
  • microcapsules have the advantage that the active ingredients are encapsulated until use and only take effect after they have been broken open. This prevents premature volatilization of the active ingredients.
  • the inner filter piece 12 according to the embodiment according to FIGS. 1 and 2 can also be provided with such microcapsules. The above description makes it very clear that the cigarette paper tube according to the invention is characterized by a high degree of freedom.
