Abstract
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 envelope 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.Cigarette buyers consider the spotless white appearance of a cigarette as an indication of quality. Even if this view is not necessarily correct - in humid climate, cigarettes can become discolored even after brief storage have that do not affect the smoke taste - the manufacturers have according to 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 the Contact points between paper and tobacco particles dissolved tobacco ingredients Can penetrate paper because 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 proposed to a quickly extinguished discarded cigarettes. To the content of various The cigarette manufacturer is generally able to control smoke ingredients interested in a certain air permeability of the cigarette paper. The The problem is, on the one hand, to keep the paper permeable to air, on the other hand to reduce the permeability for 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 the cigarette case has been proposed to solve the problem to form by two layers of paper, the inner shell being very high permeability has, so that the overall permeability remains sufficiently high. In this The possibility of adding the inner shell has already been mentioned of 0.5% alkyl ketene dimer to make it water repellent.
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. Zur Lösung dieser Aufgabe wird erfindungsgemäß eine Zigarettenhülle aus Papier mit wasserabstoßender Imprägnierung vorgesehen, welche dadurch gekennzeichnet ist, daß das Imprägniermittel ein Zellulosederivat ist. Eine derartige Imprägnierung setzt die Permeabilität herunter. Auch wenn diese auf einem für den Zigarettenhersteller hinreichend hohen Wert gehalten wird, verhindert jedoch die vorgeschlagene Imprägnierung weitgehend das Durchdringen färbender Substanzen zur Außenseite der Hülle.The object of the invention is in relation to the prior art mentioned to eliminate the need to use two layers of paper by means of an impregnating substance which is harmless and the smoky taste changed as little as possible. To solve this problem, the invention Paper cigarette case provided with water-repellent impregnation, which characterized in that the impregnating agent is a cellulose derivative. A such impregnation lowers the permeability. Even if this on one sufficiently high value for the cigarette manufacturer is prevented the proposed impregnation largely the penetration of coloring substances to the outside of the case.
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 physical requirements Conditions regarding air permeability and water impermeability of the impregnated Papers, for example sufficiently derivatized cellulose ethers and Cellulose esters (e.g. nitrocellulose). However, preference is given to ethyl cellulose, since this is with Security is harmless - it corresponds to the German tobacco regulation - and the Smoke taste practically unchanged.
Weitere Einzelheiten der Erfindung werden anschließend anhand von Vergleichsversuchen diskutiert.Further details of the invention are then based on 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 coated in a gravure printing process using a coating roller with cellulose acetoproprionate (CAP) or with cellulose acetobutyrate (CAB) or with ethyl cellulose (EC). The application quantity was approximately 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 test their susceptibility to staining, the cigarettes were packaged in and unpackaged condition either at 20 ° C and 60% rel. Humidity or at 30 ° C and 80% rel. Moist stored. The stain check (100 cigarettes each) is carried out immediately after generation and after 24 and 48 hours. Was evaluated after Spot size and number, the results were weighted in one Points system transferred.
Die Auswertung ergab folgendes Ergebnis:
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 ethyl cellulose-coated paper showed comparatively high susceptibility to staining (high score), the further development was carried out with this material, since an undesirable change in the smoke character was found in CAP and CAB. After all, even with the use of EC-coated paper, there was initially a significantly lower staining frequency compared to uncoated paper. After about a month, however, small dark spots appeared in the cigarettes made with EC-coated paper, while larger yellow spots appeared in those with uncoated paper. This suggested that through defects in the coating dyes penetrate the paper, the spreading of which is prevented by the coating. On the basis of these considerations, the tests were repeated with double-coated paper, that is with cigarette paper loaded with 1.4 g / m 2 EC. This reduced the susceptibility to stains according to the calculation method given above to 56 points, which means that it was reduced by a power of ten compared to the simple coating. This excellent result was confirmed in the long-term test.
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).It should be particularly emphasized that the success described was achieved, although the porosity of the paper, which had been 50 Coresta units before coating, was still 20 Coresta units after coating. Initial tests with more porous paper as the starting material confirm that even with an end porosity of 50 Coresta units, the radical reduction in susceptibility to staining according to the invention is achieved (a Coresta unit (CU) indicates how much cm 3 air per minute through an area of 1 cm 2 of paper flow under a pressure of 10 cm water column).
