Definitions

  • the present invention relates to a tobacco product filter, in particular a filter for a cigarette.
  • Smoke products have long been smoked in almost all cultures. In addition to the associated benefits, it has also been shown that the consumption of tobacco is hazardous to health. In particular, it has been shown that the risk of developing cancer is significantly higher among smokers.
  • filters are used which are either firmly connected to the smoking product (eg cigarette filters) or which are brought into the smoke stream each time they are smoked (eg filters for Tires) .
  • These filters are intended to retain carcinogenic tar products as well as the drug "nicotine.”
  • the taste or nicotine intake should not be reduced so much that the smoker loses the pleasure of indulging in. Many smokers even shorten filters by breaking them off to give them a stronger flavor.
  • filters made of cellulose have prevailed. This is converted into cellulose triacetate in a complex chemical process. Acetate flakes, the intermediate product, are transferred into a spindle solution with the aid of acetone. This is spun with special spinning mills into long threads that have a very specific cross-section. Very many threads are merged into a continuous band, which finally serves the cigarette industry as the basis for the filter.
  • the filter is provided with tiny holes. This is intended to dilute the smoke with air so that it contains less tar and nicotine. There is even controversy as to whether filter cigarettes are less harmful than non-filter cigarettes.
  • filter cigarettes are less harmful than non-filter cigarettes.
  • the finest fibers are transported into the lungs, increasing the number of inhaled substances.
  • the greater resistance during suction leads to a longer suction phase and thus to a lower inhalation than with filterless cigarettes.
  • the object of the present invention is now to provide an improved filter for tobacco products.
  • the filter should retain pollutants, on the other hand, it should influence the smoking experience as little as possible.
  • the tobacco should not be changed, in particular, the carbon-dependent pollutants should be minimized as possible.
  • the task is solved by a tobacco filter with a storage medium.
  • natural or synthetic zeolite is suitable as the storage medium.
  • Zeolites consist of a microporous framework structure of AIO 4 and SiO 4 tetrahedra. In this case, aluminum atoms and silicon atoms are interconnected by oxygen atoms. Depending on the type of structure, this results in a structure of uniform pores and / or channels in which substances can be absorbed. Zeolites can thus be used as sieves, since only molecules that have a smaller kinetic diameter than the pore openings of the zeolite structure absorb in the pores. Zeolites therefore also fall into the group of molecular sieves.
  • Modified zeolites can also be used according to the invention. By ion exchange or chemical treatments zeolites can be changed in this way be achieved that an increase in the catalytic activity and / or an increase in the thermal or chemical resistance is achieved.
  • zeolite has an excellent action as an ion exchanger, it can not only store pollutants, but decompose them by exchange of ions and divide them into harmless basic substances.
  • the tobacco product filter made of zeolite according to the invention has a particle size of about 1 m m to 6 m, whereby a pleasant flow of air and smoke through the tobacco product filter is made possible.
  • the advantageous properties or abilities of the storage mineral can be increased if the hydrophilic minerals are rendered hydrophobic, ie the minerals are coated in such a way that they are not moistened by the smoke or during smoking.
  • a hydrophobic coating takes place with a substance which remains free of taste under load or in the absence of heat and which is also not allowed to give off harmful substances which in turn can be detrimental. Therefore, according to the invention, a polydimethylsiloxane is advantageously used.
  • the present in appropriate particle size zeolite is sprayed m with polydimethylsiloxane and verm isik, the proportion of polydimethylsiloxane in the total mass is about 2 to 1 0%, advantageously about 5%.
  • Polydimethylsiloxane is also known by the names Dimetikon or Simetikon.
  • This additive is stable from about 240 ° C to 1600 ° C and does not disintegrate, making it extremely suitable for use in a tobacco filter.
  • an emulsion of water and polydimethylsiloxane can also be used, the tobacco product filter then containing about 2-20%, preferably 10% of this emulsion.
  • the proportion of water to polydimethylsiloxane in the emulsion is about 2: 1, preferably 35% of polydimethylsiloxane.
  • the tobacco product filter according to the invention can be used as a separate filter, for example for tires, but it can also be used without being able to insert it into a cigarette which has already been manufactured. In the latter case, it has been found that it is particularly favorable when about 500 mg of the tobacco product filter according to the invention between the previously common filter, for example made of cellulose, and the Tobacco be arranged. The best effects were achieved when the tobacco product filter according to the invention is inserted between two parts of the previous cellulose filter. The previous cellulose filter is thus divided and in between an inventive tobacco product filter is used. Theoretically, however, a m-sided arrangement at the end of the cellulose filter is possible. In principle, the tobacco product filter according to the invention can also be used without a further filter, ie instead of the previous cellulose filter.
  • the positive effect of the tobacco product filter according to the invention in a cigarette can also be increased if, in the region of the tobacco product filter according to the invention or shortly before, small, all-round incisions are made in the outer shell of the cigarette, which allow a secondary air flow which dilutes the smoke and cool the tobacco filter.
  • the effectiveness of the tobacco product filter according to the invention has been demonstrated in numerous expertises. For example, it has been shown that a conventional cellulose filter in a smoking zone of 1.5 to 4.5 cm, measured from the free end of the cigarette in the direction of the filter, about 460 mg / m 3 of substances pass, while the inventive Outer tobacco filters with secondary air slits only lets through 65 mg / m 3 . Nicotine is not completely filtered, as this would limit the enjoyment too much.
  • the tobacco product filter can also be bound with cement or a similar material and, as it were, used as a block at any point in the smoke and air flow.
  • FIG. 2 shows a structure of a cigarette with a tobacco product filter according to the invention
  • 3 shows a second embodiment variant of a cigarette with a tobacco product filter according to the invention
  • Figures 1 to 4 illustrate the invention by way of example with reference to a commercially available filter cigarette 20.
  • Figure 1 shows such a filter cigarette 20, consisting of a tobacco portion 22, to which a filter 24 connects.
  • the length ratios shown are only to be understood as examples.
  • the filter 24 shown is usually made of a cellulosic material.
  • FIG. 2 shows a first possibility of arranging a tobacco product filter 26 according to the invention.
  • the tobacco product filter 26 is integrated into the filter 24 in such a way that the overall length of the original filter 24 is substantially retained. This means that a part of the original filter 24 is replaced by the tobacco product filter 26, wherein the tobacco product filter 26 is arranged between two sections of the original filter 24.
  • the tobacco product filter 26 is preferably formed of a natural or synthetic zeolite.
  • FIG. 3 shows an embodiment variant according to the invention in which cuts 28 in the enveloping of the filter 24 enable a supply of fresh air during the aspiration of the smoke.
  • the cuts 28 shown may also have other shapes and directions, it is essential that a fresh air supply is possible, which also cools the tobacco product filter 26.
  • FIG. 4 illustrates a variant embodiment of a filter cigarette 20 according to the invention with a tobacco product filter 26, in which it is arranged directly adjacent to the tobacco portion 22, ie between the filter 24 and the tobacco portion 22.
  • the length of the original filter 24 can be maintained, but it can also be reduced by the length of the tobacco product filter 26.
  • the invention is not limited to the described embodiments, but rather includes all equivalent variants.
  • the smoke Renfilter 26 can be used in particular in filter cigarettes 20, but it can also be modified accordingly, and to be suitable for other tobacco products.
  • the tobacco product filter 26 may include, in addition to zeolite, also an emulsion of polydimethylsiloxane and water, the proportion of emulsion to the total mass of the tobacco product filter 26 being about 2 to 20%.
  • the length of a herköm union union filter cigarette 20 is about 82 m m
  • the length of the filter 24 is about 21 m m
  • the length of the tobacco portion 22 accordingly about 61 m m.
