Abstract
Description
Die Erfindung betrifft eine Filtercigarette gemäß Oberbegriff des Patentanspruchs 1.The invention relates to a filter cigarette according to the preamble of
Filter für Tabakrauch, die gänzlich aus Tabak bestehen sind seit langem bekannt. Sie besitzen gute Filtereigenschaften und sind für viele Raucher aus Gründen wie biologische Abbaubarkeit, natürliche Herkunft, ökologische Aspekte besonders attraktiv. Durch Einsetzen hocharomatischer Tabake führt dies zu verbesserten Geschmackseigenschaften des Tabakrauches.Filters for tobacco smoke, which consist entirely of tobacco have long been known. They have good filtering properties and are particularly attractive for many smokers for reasons such as biodegradability, natural origin, and ecological aspects. By using highly aromatic tobaccos this leads to improved taste characteristics of the tobacco smoke.
Nachteil von herkömmlichen Tabakfiltern ist, dass der Tabak mit den Lippen und der Zunge des Verbrauchers direkt in Berührung gelangt, was zum Anhaften von Tabak führt und zu sensorischen Irritationen führt. Auch die optische Anmutung des Tabakfilters stößt häufig auf Ablehnung.Disadvantage of conventional tobacco filters is that the tobacco comes into direct contact with the lips and the tongue of the consumer, which leads to the adhesion of tobacco and leads to sensory irritation. The visual appearance of the tobacco filter is often met with rejection.
Die
Die
Diese Verfahren und Vorgehensweisen sind jedoch umständlich und unwirtschaftlich und vermeiden nicht den direkten Kontakt des Konsumenten mit dem Tabak. Der Raucher ist weiterhin mit der Tabakoberfläche in Kontakt. Zudem stört die optische und haptische Wahrnehmung der tabakartigen Querschnittsfläche des mundseitigen Filterendes sowie die Unebenheit und mangelnde Festigkeit des Tabakfilters.However, these methods and procedures are cumbersome and uneconomical and do not avoid the direct contact of the consumer with the tobacco. The smoker is still in contact with the tobacco surface. In addition, the visual and haptic disturbs Perception of the tobacco-like cross-sectional area of the mouth-side filter end and the unevenness and lack of strength of the tobacco filter.

Der Erfindung liegt die Aufgabe zu Grunde, eine herkömmliche Filtercigarette, bei der ein Filterelement mit einem Umwickelpapier direkt mit dem Tabakstrang verbunden ist, mit einem sensorisch verbesserten und dabei einwandfreien Rauchgenuss bereitzustellen und dabei die Filtereigenschaften im Vergleich zu der Verwendung herkömmlicher Filtermaterialien zu verbessern. Gleichzeitig sollen die labialen und lingualen Störeinflüsse herkömmlicher Tabakfilter vermieden werden; ferner soll die Filterkonstruktion in ihren physikalischen Eigenschaften (Stopfdichte des Tabaks und Zugwiderstand) denen von herkömmlichen Filtercigaretten entsprechen.The invention is based on the object , a conventional filter cigarette, in which a filter element is connected to a Umwickelpapier directly to the tobacco rod, with a sensorially improved and thereby flawless smoking pleasure and thereby improve the filter properties compared to the use of conventional filter materials. At the same time, the labial and lingual perturbations of conventional tobacco filters should be avoided; Furthermore, the filter construction should correspond in their physical properties (stuffing density of the tobacco and draw resistance) to those of conventional filter cigarettes.
Weitere vorteilhafte Merkmale sind in den Unteransprüchen aufgeführt.Further advantageous features are listed in the subclaims.
Ein wesentlicher Vorteil der Erfindung besteht in der Vermeidung von lingualen, labialen und haptischen Irritationen durch Einsatz des mundseitigen Hohlfilterteils, das außerdem durch seine Oberflächenglätte angenehme haptische und optische Eigenschaften aufweist. Ein weiterer Vorteil der Erfindung ist es, dass durch den Einsatz von aromatischen Tabaken im Tabakfilter ein deutlich verbesserter Geschmack erzielt wird. Gleichzeitig ermöglicht diese Maßnahme eine deutliche Reduzierung der Materialeinsatzkosten, da im Strang weniger aromatische und damit kostengünstigere Tabake zum Einsatz kommen können. Demzufolge ist das Wesen der Erfindung die Ausbildung des Filtrationssystems aus einmal einem Tabakfilter und zum anderen einem Hohlfilter.An essential advantage of the invention is the avoidance of lingual, labial and haptic irritations by using the mouth-side hollow filter part, which also has pleasant haptic and optical properties due to its surface smoothness. Another advantage of the invention is that a significantly improved taste is achieved by the use of aromatic tobaccos in the tobacco filter. At the same time this allows Measure a significant reduction in material costs, as in the strand less aromatic and thus cheaper tobaccos can be used. Accordingly, the essence of the invention is the formation of the filtration system from once a tobacco filter and on the other hand, a hollow filter.
Zusätzlich werden mit der vorliegenden Erfindung besondere Strömungseigenschaften des Filters ausgenutzt.In addition, the present invention exploits particular flow characteristics of the filter.
Ein weiterer Vorteil besteht in der verbesserten Optik durch den erhöhten Abstand der Tabakoberfläche vom mundseitigen Filterende. Zudem werden durch den Einsatz eines Hohlfilterteils in einem Tabakfilter Materialkosten für die hocharomatischen Filtertabake eingespart.Another advantage is the improved appearance due to the increased distance of the tobacco surface from the mouth-side filter end. In addition, the use of a hollow filter part in a tobacco filter saves material costs for the highly aromatic filter tobacco.
Als aromatische Tabakfiltermaterialien werden Tabake von guter Blattqualität, wie z.B. Tabake mit einem sehr geringen Anteil an expandierten Tabaken, Rippen- oder Folientabaken oder Tabake, die zuvor einer Aromaanreicherung unterzogen wurden, eingesetzt. Die aromatische Tabakportion im Tabakfilterelement reduziert deutlich den negativen Geschmackseindruck gegenüber einteiligen künstlichen Filterelementen. Zur Aromaanreicherung des Tabakfiltermaterials können thermische Verfahren auf an sich bekannte Weise angewendet werden.As aromatic tobacco filter materials, tobaccos of good leaf quality such as e.g. Tobacco with a very small proportion of expanded tobaccos, rib or foil tobaccos or tobaccos, which were previously subjected to flavor enrichment used. The aromatic tobacco portion in the tobacco filter element significantly reduces the negative taste impression over one-piece artificial filter elements. For flavor enrichment of the tobacco filter material, thermal processes can be used in a manner known per se.
Das Strangumhüllungsmaterial kann in einer Ausführungsform aus mindestens einer Umhüllungslage rekonstituiertem Tabak oder natürlichem Tabakblatt bestehen, wobei das Deckblatt in einer spiralförmigen Wickelung angebracht ist.The strand wrapping material may in one embodiment consist of at least one wrapping layer of reconstituted tobacco or natural tobacco leaf with the topsheet mounted in a helical wrap.

Figur 1 zeigt eine erste Ausführungsform mit einem Tabakstrang 1 und einem Tabakfilterabschnitt 2, an den mundseitig ein Hohlfilterteil 3 angesetzt ist, der eine der in Figur 5 gezeigten Querschnittsformen haben kann. Die Tabakrauchströmung wird durch den Hohlfilter nach dem Coanda-Effekt so gelenkt, dass die Strömung entlang einer festen Oberfläche erfolgt. Dieser Wirbelgrenzflächeneffekt erzeugt neben der rauchstrombedingten hohen Aromaqualität eine zusätzlich erhöhte Kondensatabscheidung an der Oberfläche des Hohlfilters, ohne dass dieser eine zusätzliche Zugwiderstandserhöhung bewirkt. Figure 1 shows a first embodiment with a
Zur Reduzierung der Kondensat- und Nikotinwerte kann der Tabakfilter, wie es in Figur 2 gezeigt ist, ventiliert werden. Die Anordnung der Ventilationsmittel z.B. eine Perforationsreihe 7 ist vorzugsweise am strangseitigen Filterende vorgesehen. Sowohl der Hauptstromrauch als auch die zugeführte Ventilationsluft durchströmen dann den aromareichen Tabak über eine längstmögliche Strecke, was zur maximalen Aromaanreicherung des dem Konsumenten zugeführten Rauchstromes führt.To reduce condensate and nicotine levels, the tobacco filter as shown in Figure 2 may be ventilated. The arrangement of the ventilation means, for example, a row of

Man erkennt, dass der Mantel 9 vom Tabakstrang 1 bis zum mundseitigen Ende der Cigarette reicht, während der vom Mantel umhüllte Tabakkern 8 im Abstand zum mundseitigen Filterende endet, so dass in diesem Bereich der Hohlfilter 3 gebildet ist. FIG. 4 shows a smoke product with a coaxial or core filter with tobacco core 8 and jacket 9 made of other filter material, for example cellulose acetate. It can be seen that the jacket 9 extends from the
Der Hohlfilter 3 ist entweder ein hohles Rohr oder ein Stutzen gemäß Figur 5a, oder ein Rohr oder Stutzen mit konzentrischem Innenrohr gemäß Figur 5b. Das Innenrohr 4 hat bei der Ausführungsform nach Figur 5b einen kreisförmigen Querschnitt, während der Querschnitt bei der Ausführungsform nach Figur 5c eine rechteckige Form und nach der Figur 5d eine weitere geometrische Form aufweist. Es sind auch andere Querschnittsformen für das Innenrohr 4 möglich. Die Figuren 5e und 5f zeigen ferner Stege 5, die das Innenrohr 4 in einem äußeren Hohlfilterteil 3 tragend abstützen.The
Es wird darauf hingewiesen, dass sich die Ausführungsform nach Figur 5f von der Ausführungsform nach Figur 5e dadurch unterscheidet, dass das Innenrohr 4 beispielsweise mit Celluloseacetat gefüllt ist. Auch hierbei verbessert der vorgeschaltete Tabakfilter die negativen Gesamteindrücke der üblichen gänzlich aus Filtermaterial wie Papier oder Kunststoff bestehenden Filter.It should be noted that the embodiment according to FIG. 5f differs from the embodiment according to FIG. 5e in that the
Der Tabak, welcher im Filter eingesetzt wird, wird für einen Zeitraum zwischen 1 Minute und 15 Minuten auf eine Tabaktemperatur zwischen 60°C und 150°C, vorzugsweise 80°C gebracht und einer hohen relativen Feuchte ausgesetzt und mit einer Schnittbreite von 0,3 mm bis 0,6 mm geschnitten.
Der Tabakfilter erhält mundseitig einen Hohlfilterteil, ein sogenannter Recessfilter, und wird an einer herkömmlichen Cigarettenmaschine mit dem Tabakstrang mittels eines Umwickelpapiers verbunden. Die Cigaretten besitzen eine attraktive optische Anmutung und es treten beim Rauchen keine lingualen oder labialen Störeinflüsse auf.The tobacco, which is used in the filter is brought to a tobacco temperature between 60 ° C and 150 ° C, preferably 80 ° C and exposed to a high relative humidity and with a cutting width of 0.3 for a period of between 1 minute and 15 minutes mm to 0.6 mm cut.
On the mouth side, the tobacco filter receives a hollow filter part, a so-called recess filter, and is connected to the tobacco rod by means of a wrapping paper on a conventional cigarette machine. The cigarettes have an attractive visual appearance and there are no lingual or labial disturbances during smoking.
Beispiel 2: 200 kg Tabak werden einer Casingaufbereitung unterzogen, in einer feinen Schnittbreite von 0,3 mm bis 0,6 mm geschnitten und zu Filterteilen weiterverarbeitet. Der mundseitige Hohlfilterteil besteht aus Polyethylen, wobei die innere Röhre über drei Stege an die Außenwand des Hohlfilters verbundenen ist. Die Tabakfilter- und Hohlfilterteile werden zu Doppelfiltern verarbeitet und mit Hilfe eines Umwickelpapiers an den Tabakstrang angesetzt. Der umhüllte Tabakstrang enthielt eine Tabakmischung mit einem hohen Anteil an Rippen und preisgünstigen Tabaken. Der Zugwiderstand des erfinderischen Filters betrug 82 mm WS, lag also im Bereich der Zugwiderstände von Filtern aus herkömmlichen Materialien. Eine sensorische Prüfung in einer Gruppe von 12 freiwilligen Testpersonen ergab, dass die erfindungsgemäße Cigarette gegenüber einer Cigarette mit einstückigem Tabakfilter ohne Hohlmundstück einen deutlich besseren Geschmack zeigte. Des weiteren wurden die Testpersonen nach ihren optischen und haptischen Eindrücken befragt. Es ergab sich eine einstimmige Meinung, dass sowohl der optische, haptische und linguale bzw. labiale Störeindruck gegenüber der Vergleichscigarette deutlich gemindert ist. Example 2: 200 kg of tobacco are subjected to a casing treatment, cut into a fine cutting width of 0.3 mm to 0.6 mm and further processed into filter parts. The mouth-side hollow filter part is made of polyethylene, wherein the inner tube is connected via three webs to the outer wall of the hollow filter. The Tabakfilter- and hollow filter parts are processed into double filters and attached using a Umwickelpapiers to the tobacco rod. The wrapped tobacco rod contained a tobacco blend with a high content of ribs and low cost tobaccos. The draw resistance of the inventive filter was 82 mm WS, that is in the range of draw resistances of filters made of conventional materials. A sensory examination in a group of 12 volunteers revealed that the Cigarette according to the invention compared to a cigarette with one-piece tobacco filter without a hollow mouthpiece showed a significantly better taste. Furthermore, the test persons were asked about their visual and haptic impressions. It was a unanimous opinion that both the visual, haptic and lingual or labial disturbance impression compared to the comparison cigarette is significantly reduced.
