Definitions

  • the invention relates to a filter cartridge for smoking devices, such as tobacco pipes, cigarette and cigar tips, which consists of a spirally formed core and a porous material and a sleeve surrounding it.
  • Filter cartridges of the type in question have become known in the most varied of embodiments.
  • Limited effective filters for smoking devices contain pieces of activated carbon in a smoke-flowed sleeve, since activated carbon is particularly suitable for adsorbing the undesired constituents contained in tobacco smoke, such as nicotine, tar distillate and other substances
  • Filter cartridges of this type have various disadvantages; there are limits to their effectiveness and their costs are relatively high.
  • a cigarette fi l mouthpiece for tobacco smoke which consists of a thick-walled sleeve made of absorbent material, in the inner cavity of which there is a spiral consisting of a Core rod and a spiral wound on this consists.
  • the aim and purpose of the spiral located in the inner cavity is for the smoke to flow through the filter along a somewhat longer path than if it were to flow through it in a straight path in the axial direction.
  • the tobacco smoke is guided along the inner wall of the absorbent fi lter sleeve by the spiral, the unwanted smoke constituents being adsorbed.
  • Filter mouthpieces of this type have the disadvantage of only one to cause insufficient filtering or adsorption of the constituents to be filtered out of the smoke.
  • a similar cigarette fi lter mouthpiece is the subject of DE-GM 16 92 707.
  • a strand consisting of porous fi lter material is provided with a circular cross section with a spirally arranged smoke channel with a paper sleeve.
  • the cigarette mouthpieces of the desired length are separated from this strand.
  • the porous filter strand consists of elastic material. The filter effect of such a filter is likewise insufficient and therefore unusable in practice.
  • US Pat. No. 4,135,523 has disclosed a filter element for cigarette mouthpieces which is designed similarly to the filter mouthpieces described above. In this case, however, there is a disc that fills the entire cross section at one end, through which the tobacco smoke should pass after flowing through the spiral smoke channel.
  • the actual filter consists of cellulose acetate and is surrounded by a porous paper. The filter effect of this filter is also insufficient, especially in view of the increased requirements for the adsorption capacity of such filters today.
  • the invention is based on the object of creating a filter cartridge for smoking devices which is particularly suitable and meets the requirements made of such filters.
  • the filter should take up the smallest possible space without, however, impairing the performance of the filter.
  • the filter construction should allow a calculable result to be achieved, so that the factors influencing the effectiveness of the filter can be determined accordingly.
  • the filter cartridges in question in such a way that the multi-start screw body forming the central core is made of a porous adsorbable organic mass of protein-containing starch, which may be additional I can be added an organic binder, which may contain a proportion of activated carbon particles, and that the surface of the screw body is coated with activated carbon particles.
  • a suitable ceramic material can also be used for the screw body.
  • a spirally twisted Chen I I wire element as the screw body, the thread pieces of which protrude radially outwards from the wire core are covered with the greatest possible amount of activated carbon particles.
  • a suitable binding agent for example a cellulose adhesive or polyvinyl alcohol or the like, is used to promote adhesion. used, which does not adversely affect the adsorption of the activated carbon particles.
  • FIG. 1 shows a side view of a screw body of a filter cartridge designed according to the invention
  • FIG. 2 shows a radial view through the screw body according to FIG. 1;
  • 3a and 3b each have a wheel through a screw body in further embodiments
  • FIG. 4 shows an axial section through a filter cartridge which consists of a Chen i I I edrahtel element and a paper or cardboard sleeve surrounding it, and
  • FIG. 5 shows an axial section through a filter cartridge with a screw body according to FIG. 1 as the core, which is surrounded by a paper or cardboard sleeve.
  • the filter core shown in FIG. 1 consists of a multi-start, predominantly three-start screw body 11, which, as can be seen from FIG. 2, consists of three star-shaped belts 12 which form the cross-sections of the screw and which form the threads of the screw are connected to one another along the axis 13 and are spirally rotated about the axis 13 over the length of the screw body 11.
  • the screw body 11 can have, for example, four or even six bands 12. Of course, more such tapes 12 can also be provided.
  • the screw body 11 preferably consists of a porous material made of starch in the form of flour or semolina, which has a corresponding proportion of protein-containing adhesive. If this adhesive is not sufficient to ensure sufficient binding of the starch particles, an additional organic binder, preferably protein, can be added to the mass. A pore former and activated carbon particles are preferably added to this mass, so that on the one hand the porosity of the screw body assumes a desired size and on the other hand the adsorption capacity is increased.
  • the mass is expediently pressed by means of an extruder into a helical strand, from which the parts are then separated in the desired length.
  • the surface of the individual snail bodies is coated with activated carbon particles, which results in an extraordinarily good filtering effect.
  • the screw body shown in FIG. 4 and embodied according to the invention can also consist of a spiral Cheni I wire element 14.
  • the pieces of thread 16 clamped between two twisted wires of the core 15, which are arranged spirally along the core 15, are filled with activated carbon particles as densely as possible, a suitable binder also being used for the purpose of adhering to the thread parts .
  • the screw bodies 11 Since the previously described screw bodies 11 have relatively large tolerances with regard to predetermined dimension values in industrial production and are also more or less sensitive, and furthermore the tightness between the filter and the wall of the cavity surrounding it, in which the If a filter is used, an important role is played, the screw bodies 11 are wrapped in a paper or cardboard sleeve 17 in order to form a filter cartridge 21 which is inserted into the cavity provided in a tobacco pipe or a cigarette or cigarspitze is to be plugged in, I want it to be as close as possible to the wall of the cavity.
  • the paper or cardboard sleeve 17 is expediently also coated on the inside with adsorbing activated carbon particles, as a result of which the effectiveness of the filter is further improved.
  • activated carbon particles instead of the activated carbon particles, however, suitable fiber material can also be used, which can then also be mixed with activated carbon particles.
  • a thread or wire piece 18 is advantageously attached to this, on which one can grip around the Pull the cartridge out of the cavity that receives it.
  • the filter cartridges designed in accordance with the invention can be produced economically and in particular cost-effectively. They have a high adsorption capacity for the substances to be removed from the flue gases, which is considerably higher than that of previously used filters.

Abstract

Une cartouche filtrante pour articles pour fumeurs, par exemple les pipes à tabac, les embouts de cigarettes et de cigares, est formée d'un noyau, à conception en spirale, composé d'un matériau poreux et d'une enveloppe entourant celui-ci. Le corps spiral (11) constituant le noyau central est composé d'un matériau organique adsorptif formé d'une matière renfermant de l'albumine, à laquelle peut être ajoutée, le cas échéant, une quantité de particules de charbon actif, la surface du corps spiral (11) étant recouverte de particules de charbon actif.
