Description

Bezeich n u ng : Zigarettenf ilter Designation: cigarette filter
Die vorliegende Erfindung betrifft ein Rauchwarenfilter, insbesondere einen Filter für eine Zigarette.The present invention relates to a tobacco product filter, in particular a filter for a cigarette.
Rauchwaren werden seit langer Zeit in nahezu allen Kulturkreisen geraucht. Neben dem dam it verbundenen Genuss hat sich aber auch gezeigt, dass der Genuss von Tabak gesundheitsgefährdend ist. I nsbesondere ist nachgewiesen, dass das Risiko, an Krebs zu erkranken, bei Rauchern deutlich erhöht ist.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.
Um die gesundheitsschädlichen Bestandteile des Tabaks beim I nhalieren zu reduzieren, werden Filter eingesetzt, die entweder m it der Rauchware fest verbunden sind (z. B. Zigarettenfilter) , oder die jeweils beim Rauchen in den Rauchstrom gebracht werden (z. B. Filter für Reifen) . Diese Filter sollen zum einen krebserregende Teerprodukte und zum anderen die Droge „Nikotin" ( Nervengift) zurückhalten. Trotz ständiger Verbesserung von Filtermaterialien ist es nicht möglich, sämtliche Schadstoffe zurückzuhalten. Dies ist aber auch dadurch bedingt, dass zwar Schadstoffe zurückgehalten werden sollen, der Rauchgenuss jedoch nicht zu sehr eingeschränkt werden darf. Der Geschmack oder die Nikotinaufnahm e soll nicht derart reduziert werden, dass der Raucher die Lust am Genuss verliert. Viele Raucher verkürzen Filter sogar, indem sie sie abbrechen, um som it einen stärkeren Geschmack zu erzielen.In order to reduce the harmful components of the tobacco during inhalation, 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." Despite continual improvement of filter materials, it is not possible to retain all harmful substances, but this is due to the fact that pollutants are retained, the smoking pleasure However, 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.
Für Zigaretten haben sich Filter aus Zellulose durchgesetzt. Diese wird in einem aufwendigen chem ischen Prozess zu Zellulose Triacetat umgewandelt. Die Ace- tat-Flocken, das Zwischenprodukt, wird m it Hilfe von Aceton in eine Spindellösung übergeführt. Diese wird m it speziellen Spinnm aschinen zu langen Fäden gesponnen, die einen ganz bestim mten Querschnitt aufweisen. Sehr viele Fäden werden zu einem Endlos- Band zusam mengeführt, das schließlich der Zigarettenindustrie als Grundlage für den Filter dient.For cigarettes, 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.
Besonders bei so genannten "leichten" Zigaretten wird der Filter m it winzigen Löchern versehen. Dadurch soll der Rauch m it Luft verdünnt werden, so dass er weniger Teer und Nikotin enthält. I nzwischen ist sogar umstritten, ob Filterzigaretten weniger schädlich sind als filterlose Zigaretten. Beim I nhalieren werden feinste Fasern m it in die Lunge transportiert, die die Anzahl der inhalierten Substanzen steigern. Gleichzeitig führt der größere Widerstand beim Saugen zu einer längeren Saugphase und som it zu einer tieferen I nhalation als bei filterlosen Zigaretten.Especially with so-called "light" cigarettes, 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. When inhaling, the finest fibers are transported into the lungs, increasing the number of inhaled substances. At the same time, the greater resistance during suction leads to a longer suction phase and thus to a lower inhalation than with filterless cigarettes.
Die Aufgabe der vorliegenden Erfindung besteht nun darin, einen verbesserten Filter für Rauchwaren zu schaffen. Der Filter soll zum einen Schadstoffe zurückhalten, zum anderen aber den Rauchgenuss möglichst wenig beeinflussen. Der Tabak soll nicht verändert werden, insbesondere sollen die kohlenabhängigen Schadstoffe möglichst elim iniert werden.The object of the present invention is now to provide an improved filter for tobacco products. On the one hand, 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.
Die Aufgabe wird durch einen Rauchwarenfilter m it einem Speicherm ineral gelöst.The task is solved by a tobacco filter with a storage medium.
Als Speicherm aterial kom mt insbesondere natürliches oder synthetisches Zeo lith in Frage. Hinzu kom m en u.a. Zeolith- Variitäten, wie Skolezit und Natrolith. I n gro ßen Mengen verwendete natürliche Zeolithe sind Klinopt ilolit h und Heulandit. Zeolith oder Siedestein bezeichnet eine lockere Gruppe chem isch sehr kom plexer Silikat- Minerale. Zeolith hat eine variable Farbe, weiß, gelb, braun oder rosa sind auch oft vertreten, auch farblose Varianten existieren. Wesentlich ist, dass das Mineral je nach Typ bis etwa 40 % des Trockengewichts an Wasser speichern kann.In particular, natural or synthetic zeolite is suitable as the storage medium. In addition, com m u. A. Zeolite varieties such as scolecite and natrolite. Natural zeolites used in large quantities are clinoptilithite and heulandite. Zeolite or boiling stone refers to a loose group of chemically very complex silicate minerals. Zeolite has a variable color, white, yellow, brown or pink are also often represented, even colorless variants exist. It is essential that the mineral, depending on the type, can store up to about 40% of the dry weight of water.
Zeolithe bestehen aus einer m ikroporösen Gerüststruktur aus AIO4 - und SiO4- Tetraedern. Dabei sind Alum inium - und Silizium -Atome untereinander durch Sauerstoffatome verbunden. Je nach Strukturtyp ergibt sich dadurch eine Struktur aus gleichförm igen Poren und/oder Kanälen, in denen Stoffe absorbiert werden können. Zeolithe können dam it gleichsam als Siebe verwendet werden, da nur Moleküle in den Poren absorbieren, welche einen kleineren kinetischen Durchmesser besitzen als die Porenöffnungen der Zelolithstruktur. Zeolithe fallen daher auch in die Gruppe der Molekularsiebe.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.
Erfindungsgemäß können auch modifizierte Zeolithe eingesetzt werden. Durch l onenaustausch oder chem ische Behandlungen können Zeolithe derart verändert werden, dass eine Erhöhung der katalytischen Wirkung und/ oder eine Erhöhung der therm ischen oder chem ischen Beständigkeit erzielt wird.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.
Zeolith hat weiterhin eine ausgezeichnete Wirkung als l onentauscher, es kann Schadstoffe nicht nur speichern, sondern auf dem Wege des l onentausches zerlegen und in harm lose Grundsubstanzen aufteilen.Furthermore, 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.
Vorteilhafterweise weist der erfindungsgemäße Rauchwarenfilter aus Zeolith eine Korngröße von ca. 1 m m bis 6 m m auf, wodurch ein angenehmer Luft- und Rauchstrom durch den Rauchwarenfilter ermöglicht wird.Advantageously, 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.
Erfindungsgemäß können die vorteilhaften Eigenschaften oder Fähigkeiten des Speicherm inerals dadurch erhöht werden, wenn die hydrophilen Mineralien hydrophobiert werden, also die Mineralien derart beschichtet werden, dass sie vom Rauch oder während des Rauchens nicht befeuchtet werden.According to the invention, 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.
Vorteilhafterweise erfolgt eine solche hydrophobe Beschichtung m it einem Stoff, der unter Belastung bzw. bei Hitze geschmacksfrei bleibt und auch keine Schadstoffe abgeben darf, die ihrerseits schädlich sein können. Erfindungsgemäß wird deshalb vorteilhafterweise ein Polydim ethylsiloxan verwendet. Das in entsprechender Korngröße vorliegende Zeolith wird m it Polydimethylsiloxan eingesprüht und verm ischt, der Anteil an Polydimethylsiloxan an der Gesamtmasse beträgt etwa 2 bis 1 0% , vorteilhafterweise etwa 5% . Polydimethylsiloxan ist auch unter den Bezeichnungen Dimetikon oder Simetikon bekannt. Dieser Zusatzstoff ist von m inus 240 ° C bis 1 .600 ° C stabil und zerfällt nicht, so dass es für einen Einsatz in einem Rauchwarenfilter äu ßerst geeignet ist. Erfindungsgemäß ist auch eine Em ulsion aus Wasser und Polydim ethylsiloxan verwendbar, der Rauchwarenfilter beinhaltet dann etwa 2-20% , vorzugsweise 10% dieser Em ulsion. Der Anteil von Wasser zu Polydimethylsiloxan in der Em ulsion beträgt etwa 2: 1 , vorzugsweise 35% an Polydimethylsiloxan.Advantageously, such 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. According to the invention, 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.
Der erfindungsgemäße Rauchwarenfilter kann als separater Filter beispielsweise für Reifen eingesetzt werden, er kann aber auch unm ittelbar in eine bereits gefertigte Zigarette eingesetzt sein. I m letzteren Fall hat sich gezeigt, dass es besonders günstig ist, wenn etwa 500 mg des erfindungsgemäßen Rauchwarenfilters zwischen dem bisher üblichen Filter, beispielsweise aus Zellulose, und dem Tabak angeordnet werden. Die besten Wirkungen wurden dann erzielt, wenn der erfindungsgemäße Rauchwarenfilter zwischen zwei Teile des bisherigen Zellulosefilters eingefügt wird. Der bisherige Zellulosefilter wird also geteilt und dazwischen wird ein erfindungsgemäßer Rauchwarenfilter eingesetzt. Theoretisch ist aber auch eine m undseitige Anordnung am Ende des Zellulosefilters möglich. Grundsätzlich kann der erfindungsgemäße Rauchwarenfilter auch ohne einen weiteren Filter, also anstelle des bisherigen Zellulosefilters eingesetzt werden.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.
Die positive Wirkung des erfindungsgemäßen Rauchwarenfilters in einer Zigarette lässt sich weiterhin erfindungsgemäß auch dadurch steigern, wenn im Bereich des erfindungsgemäßen Rauchwarenfilters oder kurz davor kleine, rund umlaufende Einschnitte in den Au ßenmantel der Zigarette eingebracht werden, die einen Nebenluftstrom ermöglichen, der den Rauch verdünnt und den Rauchwarenfilter kühlt.According to the invention, 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.
Die Wirksam keit des erfindungsgemäßen Rauchwarenfilters wurde in zahlreichen Expertisen nachgewiesen. Beispielsweise hat sich gezeigt, dass ein herköm m licher Zellulosefilter in einer Rauchzone von 1 ,5 bis 4,5 cm , gemessen ab dem freien Ende der Zigarette in Richtung des Filters, etwa 460 mg/m 3 an Substanzen passieren lässt, während der erfindungsgem äße Rauchwarenfilter m it Neben- lufteinschnitten nur 65 mg/m 3 durchlässt. Nikotin wird dabei nicht vollständig gefiltert, da dies den Genuss zu stark einschränken würde.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.
Der Rauchwarenfilter kann auch m it Zement oder einem ähnlichen Material gebunden werden und sozusagen als Block an beliebiger Stelle im Rauch- und Luftstrom eingesetzt werden.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.
