Definitions

  • Such a system is e.g. B. known from DE-C-34 07 461 and EP-A-155 514.
  • the present invention is based on the object of improving the aforementioned system in terms of taste and / or retention of the filter without having to make changes to the conventionally used filters, in particular acetate filters.
  • the smoking behavior, retention and / or the taste of the tobacco smoke can be varied or adjusted in a simple manner by appropriate changes to the filter piece additionally attached to a front end of the tobacco portion.
  • the length of the tobacco portion together with the additionally attached filter piece corresponds to the length of the normally available tobacco receiving space of the filter cigarette paper sleeve or sleeve.
  • the system according to the invention is characterized by a type of Duplo filter.
  • the air inlet openings in the cigarette paper according to claim 5 are now produced by laser technology.
  • the system is characterized by more secondary air, so that the smoker reach less pollutants.
  • the attached filter piece is mixed with retention-specific substances, in particular with activated carbon and / or silica gel.
  • taste-influencing active substances can be provided in the attached filter piece, these active substances being e.g. B. can also be in microcapsules that can be broken open by light finger pressure from the outside without this finger pressure remaining visible on the cigarette paper.
  • the filter piece used can also be a mere acetate filter, which is enriched with retention-specific and / or taste-influencing active ingredients.
  • the additional filter piece is held within this wrapper.
  • these binders preferably serve at the same time for fixing the filter piece attached on the end face, the end face of the filter piece facing the tobacco portion and axially extending depressions and / or to improve the bond between the tobacco portion and the filter piece Has surveys so that a kind of toothing between tobacco and filter piece is achieved.
  • FIG. 1 shows an industrially prefabricated, dimensionally stable tobacco portion 10 in association with a likewise industrially prefabricated cigarette paper tube 11 with a conventional acetate filter 12 of the conventional type used by self-tampers.
  • the essential element of the system is the dimensionally stable tobacco portion, which is non-smokable outside the cigarette paper tube 11 otherwise consists entirely of smokable material, and on one end face an additional filter piece 13 is attached, which in the convectioned state according to FIG. 2 directly on the acetate filter 12 prefabricated cigarette paper sleeve is present. Accordingly, you get a kind of Duplo filter with the assembled cigarette.
  • the tobacco portion 10 consists of a covering 14 made of thin cellulose fleece which is extremely porous, the porosity being represented schematically by the holes or pores 15.
  • the porosity 15 extends over the entire length of the tobacco portion 10.
  • the additional filter piece 13 is held in the casing 14 in direct contact with the tobacco filling 16.
  • the porosity 15 is set such that the tobacco portion 10 is not smokable as such.
  • the tobacco filling 16 in the wrapper 14 is about as tightly packed as in an industrially manufactured cigarette.
  • the tobacco portion, including the attached filter piece has a length that corresponds approximately to the length of the tobacco receiving space 17 of a commercially available cigarette paper tube 11.
  • the outer diameter of the tobacco portion is slightly smaller than the inner diameter of the cigarette paper tube 11, so that it can be inserted or inserted into the cigarette paper tube 11 without any problems.
  • the outside diameter of the tobacco portion 10 is preferably approximately 1/20 - 3/10 mm smaller than the inside diameter of the cigarette paper tube. In this constellation, the tobacco portion 10 can be inserted into the prefabricated cigarette paper tube without any tools; on the other hand, flawless wearability of the cigarette thus produced is guaranteed.
  • the system according to the invention is also suitable for use in connection with rolling papers of cigarette paper, as is used in a conventional manner by self-turning machines.
  • the system also includes a conventional filter that is also screwed in.
  • a conventional filter and the prefabricated tobacco portion with attached filter piece are thus screwed in through the cigarette papers and glued in a conventional manner to form a longitudinal seam.
  • this way of producing cigarettes is extremely skillful Requires, since it is usually not possible to wrap the cigarette papers sufficiently tightly around the filter and tobacco portion and to glue them together.
  • this system has the disadvantage over the system with a prefabricated cigarette paper sleeve that cigarette paper papers generally have a longitudinal fold that always remains visible, so that everyone knows immediately that it is a self-made, namely self-rolled cigarette. Furthermore, there is the disadvantage that a cigarette manufactured in this way cannot be offered to a third party due to the formation of adhesive seams with saliva.
  • the filter piece 13 can be slightly tapered towards the free end.
  • the attached filter piece 13 can be a porous, i.e. H. have air-permeable outer surface, which in the convection state, d. H. in the finished cigarette, air inlet openings 18 in the cigarette paper are assigned. This gives a known ventilation effect in front of the actual filter 12. In this way, the smoker also draws in ambient air.
  • the air inlet openings 18 are preferably produced by conventional laser technology.
  • the attached filter piece 13 can be mixed with retention-specific substances, in particular with activated carbon and / or silica gel. It is also possible to provide taste-influencing active ingredients, such as menthol or the like. These active ingredients can e.g. B. are located in so-called microcapsule, which can be broken open from the outside by light finger pressure, the finger pressure being so light that the cigarette paper of the cigarette paper tube 11 is not damaged or crushed thereby.
  • microcapsules have the advantage that the active ingredients are encapsulated until use and only take effect after they have been broken open. An early one This prevents volatilization of the active ingredients.
  • the filter piece 13 has approximately the same cross section as the tobacco filling 16 inside the casing 14.
