Definitions

  • the invention relates to a filter for tobacco products and smoking utensils, in particular for cigarettes, cigarette tubes, cigarette holders and cigar holders according to the preamble of claim 1.
  • Such a filter is known from DE-GM 1 818 066.
  • a cigarette holder with a gas mixing chamber, but without a filter core, is described in DE-PS 586 839. With these filters The air streams entering through the holes in the jacket of the gas mixing chamber should cause the smoke to swirl and thereby separate condensable components.
  • filters in different embodiments are known as absorption and turbulence filters.
  • the absorption filters include the usual cellulose and carbon filters as used in filter cigarettes.
  • Turbulence filters have inserts which divide the inside of the filter jacket into a multiplicity of chambers, on the walls of which the heavy particles of smoke, which are mainly formed by condensate, separate.
  • the known filters are more or less effective in separating condensable smoke components, but they are not suitable for reducing the smoke content of carbon monoxide and other noxious substances.
  • the object of the invention is to create a filter which is suitable for tobacco products and smoking utensils and which also has a very high effectiveness in eliminating carbon monoxide and other noxious substances.
  • the filter core can consist of a cellulose stick in a conventional manner.
  • the gas mixing chamber can then be delimited by an insert which adjoins the cellulose rod and forms the perforated wall which closes the gas mixing chamber at the end of the smoke inlet.
  • the gas mixing chamber can advantageously form a unit with a filter core known per se, the smoke channels of which are delimited by a helical web or by disk-shaped transverse walls.
  • two gas mixing chambers connected axially one behind the other can also be arranged in front of the filter core and are separated from one another by a wall having openings.
  • a chamber is also arranged at the smoke outlet end of the filter, which opens out into narrow spaces arranged in the extension of the filter core in a space enclosed by the rear section of the filter jacket.
  • Such a pen prevents the smoke emerging from the filter from striking the tongue with a strong jet, particularly when the filter is used directly as a cigarette holder. Rather, the smoke is deflected radially by the central pin and distributed in a pleasant way over the entire oral cavity of the smoker.
  • the cigarette shown in Fig. 1 consists in a known manner of a tobacco rod 1 arranged in a paper tube and a roll 2 of fiber material arranged at the rear end of the paper tube. Between the rear end of the tobacco rod 1 and the front end of the roll 2 of fibrous material, a pot-shaped insert 3 is arranged, the bottom 4 provided with holes facing the tobacco rod and supporting the rear end of the tobacco rod. With the ends of its tubular wall, the pot-shaped insert is supported at the end of the roller 2.
  • This pot-shaped insert 2 defines a gas mixing chamber into which the smoke can enter through the holes 5 in the bottom 4 of the insert 3.
  • Fig. 3 illustrates how the air entering through the holes 6 in the direction of the arrows 7 and the smoke jets 8 entering through the holes 5 cause vortices within the gas mixing chamber and thereby thorough mixing and partial conversion of the smoke components with one another and with the inflow of fresh air cause.
  • the bottom 4 of the insert 3 has five holes 5 of 1.7 mm in diameter.
  • the holes 6 in the jacket of the gas mixing chamber are dimensioned such that the air flowing into the gas mixing chamber is approximately 10 vol.% Of the tobacco smoke. 3, two diametric holes 6 are provided. At If necessary, the number of holes can also be reduced or increased.
  • Fig. 4 shows an arrangement with three holes 6 'evenly distributed over the circumference of the insert 3'.
  • the cigarette holder essentially consists of a cylindrical tube 11, which forms the filter jacket, and a filter core inserted into the filter jacket, which consists of a central rod 12 and a helical web 13 surrounding the rod. This web extends to the inside of the filter jacket 11 and accordingly forms a helical channel which passes through the filter jacket 11 essentially over its entire length.
  • the rod 12 carries a disc 14, which serves as an abutment for a cigarette 15 inserted into the filter jacket 11, indicated by dash-dotted lines in FIG. 5, and has radial slots 16 (FIG. 7) which form passages for tobacco smoke.
  • the disk 14 could also have holes 5 as are in the bottom 4 of the insert 3 according to FIG. 1.
  • this gas mixing chamber is arranged in front of the actual filter, that is, in front of the areas in which the condensate and nicotine are separated.
  • the filter shown in FIG. 5 immediately forms a cigarette holder and is accordingly provided with a kind of mouthpiece.
  • the filter jacket 11 at the smoke outlet end has an inwardly turned section 21, on which the rod 12 of the filter core is attached with a cup-shaped extension 22.
  • a chamber 23 is also created behind the filter, in which the smoke can relax before it exits through longitudinal slots 24 into the opening 25 of the cigarette holder formed by the filter.
  • This opening 25 forming the mouthpiece is formed by the space which is enclosed by the turned-back portion 21 of the filter jacket 11.
  • the longitudinal slots 24 are located in the wall of the pot 22, with which the filter core is pushed onto the inserted section 21 of the filter jacket 11.
  • a pin 26 is arranged in the extension of the rod 12 of the filter core, which extends coaxially into the space 25 and prevents the smoke from escaping from the tip of the cigarette as a sharp jet. Rather, the pin 26 causes a very pleasant distribution of the smoke over the oral cavity.
  • Another very attractive method for improving the filter effect is to connect two gas mixing chambers axially one behind the other before the filter insert, as is shown in FIG. 5 by the dashed wall 14 'which delimits a second gas mixing chamber 18'.
  • the wall 14 ' is provided with holes 5' for the passage of smoke.
  • FIGS. 8 to 10 The embodiment of the invention shown in FIGS. 8 to 10 is a cigarette holder very similar to the embodiment of FIG. 5 with an integrated turbulence filter.
  • An essential difference is only that the central rod 32 of the filter core arranged in the filter jacket 31 does not carry a helical web, but rather disk-shaped transverse walls 33, which in turn are connected to one another by walls 34 extending in the axial direction.
  • the transverse walls 33 alternately have recesses 35 located on different sides of the longitudinal walls 34, which form openings for the passage of smoke, so that here too there is a kind of spiral path on which the smoke must pass through the filter core.
  • This type of filter core design is known per se. As in the embodiment according to FIG.
  • the filter core is also preceded by a gas mixing chamber 38 which is delimited by disks 35, 36, of which the wall 35 in turn has holes 37 for the smoke to pass through, while the disk 36 has one at its edge Opens opening 39 for the passage of smoke.
  • the design of the mouthpiece is the same as in the embodiment according to FIG. 5.
  • the mode of operation is also essentially the same.
  • FIG. 11 illustrates a modified form of the mouthpiece, as can be used with a cigarette holder according to FIGS. 5 and 8.
  • the cup-shaped extension 52 engages at the end of the rod 42 of the filter core at a distance between the filter jacket 41 and its inwardly turned section 51, so that two mutually coaxial cavities 53, 54 are formed within the area delimited by the turned section 51, which are formed by Slots 55 communicate with each other, which are located in the cup-shaped extension 52 of the rod 42.
  • This design of the mouthpiece results in a kind of labyrinth, which still provides increased security against the escape of condensate from the cigarette holder.
  • such a filter can be designed directly as a cigarette tip 61. With such a tip, twelve to fifteen cigarettes can be smoked without the filtering effect weakening significantly.
  • the use of the mouthpiece according to FIG. 11 even makes it possible to smoke fifteen to twenty cigarettes with a filter tip before problems occur when the tip is used.
  • the use of turbulence filters has the advantage over fiber filters in that their effect does not deteriorate appreciably with the increasing absorption of pollutants, because the effective surfaces on which the pollutants condense are not significantly diminished by their use or their effect is impaired.
  • the filter will become unusable because the narrow channels contained therein clog or condensate escapes from the smoke outlet end of the filter.
  • a labyrinth according to FIG. 11 enables to provide larger flow cross-sections at the smoke outlet end so that a blockage cannot occur so quickly, while at the same time the provided labyrinth largely prevents condensate from escaping.
  • filters according to the invention with a gas mixing chamber can be produced in a wide variety of embodiments depending on the desired use.
  • the inserts used in filter cigarettes can also form two gas mixing chambers connected axially one behind the other and / or can be designed in a similar manner to the corresponding sections of the filters according to FIGS. 5 and 8.
