Description

Der Erfindung liegt das Problem zugrunde, die Bildung von Flecken auf der Hülle von Zigaretten zu vermeiden.The invention is based on the problem of the formation of stains on the shell of To avoid cigarettes.

Die Käufer von Zigaretten betrachten das fleckenlos weiße Aussehen einer Zigarette als Hinweis auf die Qualität. Auch wenn diese Auffassung nicht unbedingt richtig ist - in feuchtwarmem Klima können Zigaretten auch nach kurzer Lagerung Verfärbungen aufweisen, welche den Rauchgeschmack nicht beeinträchtigen - haben sich die Hersteller nach den Erwartungen des Marktes zu richten.Buyers of cigarettes look at the spotless white appearance of a cigarette as an indication of the quality. Even if this view is not necessarily correct - in In warm and humid climates, cigarettes can discoloration even after a short storage period have, which do not affect the taste of smoke - have the manufacturers to meet the expectations of the market.

Die Fleckenbildung auf Zigarettenpapier läßt sich dadurch erklären, daß an den Kontaktstellen zwischen Papier und Tabakteilchen gelöste Tabakinhaltsstoffe das Papier durchdringen können, da dieses sowohl porös wie hydrophil ist.The staining on cigarette paper can be explained by the fact that to the Contact points between paper and tobacco particles dissolved tobacco ingredients the Penetrate paper as it is both porous and hydrophilic.

Es wäre vorstellbar, die Fleckenbildung bei Zigarettenpapier herabzusetzen, indem dieses mit irgendwelchen Substanzen beschichtet wird, welche das Papier völlig undurchlässig machen. Solche Beschichtungen wurden vorgeschlagen, um ein rasches Verlöschen abgelegter Zigaretten zu bewirken. Um den Gehalt verschiedener Rauchinhaltsstoffe kontrollieren zu können, ist der Zigarettenhersteller im allgemeinen jedoch an einer gewissen Luftdurchlässigkeit des Zigarettenpapiers interessiert. Das Problem besteht somit darin, einerseits das Papier für Luft durchlässig zu halten, andererseits die Durchlässigkeit für gelöste Zigarettenbestandteile herabzusetzen.It would be conceivable to reduce the staining of cigarette paper by this is coated with any substances that make the paper completely make impermeable. Such coatings have been suggested to be to cause rapid extinction of stored cigarettes. To the content of different Being able to control smoke ingredients is generally the cigarette maker However, interested in a certain air permeability of the cigarette paper. The Problem is, on the one hand, to keep the paper permeable to air, on the other hand, to reduce the permeability to dissolved cigarette components.

in US-A 5,143 099 ist zur Lösung des Problems vorgeschlagen worden, die Zigarettenhülle durch zwei Lagen Papier zu bilden, wobei die innere Hülle sehr hohe Permeabilität aufweist, damit die Gesamtpermeabilität hinreichend hoch bleibt. In diesem Zusammenhang wurde bereits die Möglichkeit erwähnt, die innere Hülle durch Zugabe von 0,5% Alkylketendimer wasserabstoßend zu machen.in US-A 5,143,099 has been proposed to solve the problem, the cigarette wrapper by forming two layers of paper, the inner shell having very high permeability so that the total permeability remains sufficiently high. In this In connection, the possibility has already been mentioned of adding the inner shell by adding of 0.5% alkyl ketene dimer to repel water.

Der Erfindung liegt gegenüber dem erwähnten Stand der Technik die Aufgabe zugrunde, die Verwendung von zwei Lagen Papier überflüssig zu machen, und zwar mittels eines Imprägnierstoffes, welcher unschädlich ist und den Rauchgeschmack möglichst wenig verändert. The invention is compared to the mentioned prior art, the task to make the use of two layers of paper redundant, namely by means of an impregnating substance, which is harmless and the smoke taste changed as little as possible.

Es war überraschend, daß es zur Lösung der Aufgabe führen würde, die Zigarette mit einer Hülle zu versehen, welche eine Lage aus Papier mit wasserabstoßender Imprägnierung aus einem Zellulosederivat, insbesondere aus Ethylzellulose, umfaßt. EP 0 419 981 zeigt nämlich eine solche Zigarette, bei welcher jedoch die Luftdurchlässigkeit unter 5 Coresta-Einheiten liegt.It was surprising that it would lead to the solution, the cigarette with to provide a cover which is a layer of paper with water repellent Impregnation of a cellulose derivative, in particular of ethyl cellulose. Namely, EP 0 419 981 shows such a cigarette, in which, however, the Air permeability is less than 5 Coresta units.

Erfindungsgemäß ist vorgesehen, daß zur Erzielung einer Luftdurchlässigkeit der Hülle von wenigstens 20, vorzugsweise wenigstens 50 Coresta-Einheiten, das Zellulosederivat in mehreren Schichten aufgetragen ist.According to the invention it is provided that the Achieving an air permeability of the shell of at least 20, preferably at least 50 Coresta units, the cellulose derivative in multiple layers is applied.

An sich erfüllen verschiedene Zellulosederivate die gestellten physikalischen Bedingungen hinsichtlich Luftdurchlässigkeit und Wasserundurchlässigkeit des imprägnierten Papiers, beispielsweise hinreichend hoch derivatisierte Zelluloseether und Zelluloseester (z.B. Nitrozellulose). Bevorzugt wird jedoch Ethylzellulose, da diese mit Sicherheit unschädlich ist - sie entspricht der deutschen Tabakverordnung - und den Rauchgeschmack praktisch nicht verändert.As such, various cellulose derivatives fulfill the stated physical requirements Conditions regarding air permeability and water impermeability of the impregnated Papiers, for example, sufficiently highly derivatized cellulose ethers and Cellulose esters (e.g., nitrocellulose). However, ethylcellulose is preferred, since these with Safety is harmless - it corresponds to the German tobacco regulation - and the Smoky taste practically unchanged.

Weitere Einzelheiten der Erfindung werden anschließend anhand von Vergleichsversuchen diskutiert.Further details of the invention will subsequently be described by way of comparative experiments discussed.

Zigarettenpapier mit einem Flächengewicht von 26 g/m2 wurde im Tiefdruckverfahren mittels einer Beschichtungswalze mit Zelluloseazetoproprionat (CAP) oder mit Zelluloseazetobutyrat (CAB) oder mit Ethylzellulose (EC) beschichtet. Die Auftragsmenge betrug etwa 0,7 g/m2. Mit dem so hergestellten Zigarettenpapier wurden Zigaretten hergestellt.Cigarette paper with a basis weight of 26 g / m 2 was gravure coated by means of a coating roll with cellulose acetoproprionate (CAP) or with cellulose acetate butyrate (CAB) or with ethyl cellulose (EC). The application rate was about 0.7 g / m 2 . Cigarettes were produced with the cigarette paper thus produced.

Zur Prüfung auf ihre Fleckenanfälligkeit wurden die Zigaretten in verpacktem und unverpacktem Zustand entweder bei 20°C und 60% rel. Luftfeuchte oder bei 30°C und 80% rel. Feuchte gelagert. Die Fleckenüberprüfung (jeweils 100 Zigaretten) erfolgt sofort nach Erzeugung sowie nach 24 und 48 Stunden. Ausgewertet wurde nach Fleckengröße und Anzahl, über eine Gewichtung wurden die Ergebnisse in ein Punktesystem überführt.To check for their staining, the cigarettes were packed in and unpackaged state either at 20 ° C and 60% rel. Humidity or at 30 ° C and 80% rel. Moisture stored. The stain check (100 cigarettes each) takes place immediately after production as well as after 24 and 48 hours. It was evaluated after Stain size and number, over a weighting were the results in one Transferred points system.

Die Auswertung ergab folgendes Ergebnis: Beschichtung mit 0,7 g EC 572 Punkte Beschichtung mit 0,7 g CAP 223 Punkte Beschichtung mit 0,7 g CAB 77 Punkte The evaluation gave the following result: Coating with 0.7 g EC 572 points Coating with 0.7 g CAP 223 points Coating with 0.7 g CAB 77 points

Obwohl ethylzellulosebeschichtetes Papier vergleichsweise starke Fleckenanfälligkeit (hohe Punktezahl) zeigte, wurde die weitere Entwicklung mit diesem Material durchgeführt, da bei CAP und CAB eine unerwünschte Veränderung des Rauchcharakters festgestellt wurde. Immerhin war ja auch bei Verwendung von EC-beschichtetem Papier im Vergleich zu unbeschichtetem Papier zunächst eine wesentlich geringere Fleckenhäufigkeit festzustellen. Nach etwa einem Monat zeigte sich jedoch bei den mit EC beschichteten Papier hergestellten Zigaretten kleine dunkle Flecken, während bei solchen mit unbeschichtetem Papier größere gelbe Flecken auftraten. Dies legte die Vermutung nahe, daß durch Fehlstellen in der Beschichtung Farbstoffe in das Papier eindringen, deren Ausbreitung durch die Beschichtung unterbunden wird. Aufgrund dieser Überlegungen wurden die Versuche mit zweifach beschichtetem Papier wiederholt, also mit Zigarettenpapier, das mit 1,4 g/m2 EC beladen war. Damit sank die Fleckenanfälligkeit nach der oben wiedergegebenen Berechnungsmethode auf 56 Punkte, reduzierte sich also gegenüber der einfachen Beschichtung um eine Zehnerpotenz. Dieses hervorragende Ergebnis bestätigte sich im Langzeitversuch.Although ethylcellulose-coated paper showed relatively high susceptibility to staining (high score), further development was performed with this material because of an undesirable change in the smoke character of CAP and CAB. After all, even with the use of EC-coated paper compared to uncoated paper, a significantly lower stain frequency was initially observed. However, after about one month, the cigarettes made with EC-coated paper showed small dark spots, while those with uncoated paper had larger yellow spots. This suggested that by defects in the coating dyes penetrate into the paper, whose spread is prevented by the coating. Based on these considerations, the experiments were repeated with double-coated paper, ie with cigarette paper loaded with 1.4 g / m 2 EC. Thus, the susceptibility to staining decreased to 56 points according to the calculation method reproduced above, thus reducing by one order of magnitude compared to the simple coating. This excellent result was confirmed in the long-term trial.

Besonders zu betonen ist, daß der beschriebene Erfolg erreicht wurde, obwohl die Porosität des Papiers, welche vor der Beschichtung 50 Coresta-Einheiten betragen hatte, nach der Beschichtung immer noch 20 Coresta-Einheiten betrug. Erste Versuche mit stärker porösem Papier als Ausgangsmaterial bestätigen, daß auch bei einer Endporosität von 50 Coresta-Einheiten die erfindungsgemäße radikale Verminderung der Fleckenanfälligkeit erzielt wird (eine Coresta-Einheit (CU) gibt an, wieviel cm3 Luft pro Minute durch eine Fläche von 1 cm2 Papier unter einem Druck von 10 cm Wassersäule fließen).Of particular note is that the described success was achieved although the porosity of the paper, which before coating was 50 Coresta units, was still 20 coresta units after coating. First experiments with more porous paper as starting material confirm that even with a final porosity of 50 Coresta units, the inventive radical reduction of stain-susceptibility is achieved (a Coresta unit (CU) indicates how many cm 3 of air per minute through an area of 1 cm 2 of paper flow under a pressure of 10 cm of water).
