Description

Rauchwarenumhüllungsmaterial mit verbesserten Kohlenmonoxidreduzierungseigenschaften Smoking article wrapping material with improved carbon monoxide reduction properties
Beschreibung:Description:
Die vorliegende Erfindung betrifft ein verbessertes Rauchwarenumhüllungsmaterial, das bei Rauchwaren, z.B. Zigaretten, das Kohlenmonoxid als Bestandteil von Rauchinhaltsstoffen reduziert, ohne dass die Luftdurchlässigkeit des Rauchwarenumhüllungspapiers im unverbrannten Zustand verändert wird.The present invention relates to an improved smoking article wrapping material useful in smoking articles, e.g. Cigarettes that reduce carbon monoxide as a constituent of smoke ingredients without altering the air permeability of the tobacco wrapper paper in the unburned state.
Auf dem einschlägigen Fachgebiet ist es bekannt, dass durch Erhöhung der Luftdurchlässigkeit des Rauchwarenumhüllungspapiers oder durch Veränderung des Anteiles von organischen (z. B. Zellulose) und anorganischen Substanzen (z.B. Füllstoff, vorzugsweise Calciumcarbonat) im Rauchwarenumhüllungsmaterial (vgl. beispielsweise CA-A-2065788) oder durch Reduzierung der Masse des Rauchwarenumhüllungsmaterials (vgl. beispielsweise WO-A-03/034846) oder durch Einsatz von Katalysatoren eine Reduzierung des Kohlenmonoxid (CO) als Bestandteil der Rauchinhaltsstoffe erreicht werden kann.It is known in the art that by increasing the air permeability of the tobacco wrapper paper or by altering the content of organic (eg, cellulose) and inorganic substances (eg, filler, preferably calcium carbonate) in the smoking article wrapping material (see, for example, CA-A-2065788 ) or by reducing the mass of the tobacco product wrapping material (see, for example, WO-A-03/034846) or by using catalysts, a reduction of the carbon monoxide (CO) can be achieved as part of the smoke ingredients.
Die bekannten Erfindungen und Anwendungen zielen direkt oder indirekt auf eine Veränderung der Luftdurchlässigkeit des Rauchwarenumhüllungsmaterials ab, wodurch in nur wenig veränderten Verhältnissen alle Rauchinhaltsstoffe reduziert und die Zugzahl der Rauchwaren verändert werden.The known inventions and applications are aimed directly or indirectly at a change in the air permeability of the tobacco product wrapping material, which reduces all smoke ingredients and changed the number of smoking products in only slightly changed proportions.
Häufig erzielen diese Lösungen jedoch nur eine geringe Reduzierung des Kohlenmonoxidgehalts oder das Verhältnis der Rauchinhaltsstoffe, insbesondere das durch gesetzliche Regulierungsmaßnahmen interessierende Verhältnis von CO und Trockenkondensat, wird nur unwesentlich beeinflusst.Frequently, however, these solutions only achieve a slight reduction in the carbon monoxide content or the ratio of the smoke constituents, in particular the ratio of CO and dry condensate, which is of interest due to legal regulation measures, is only insignificantly influenced.
Ferner verändern die im Stand der Technik eingesetzten Katalysatoren zur Reduzierung von CO das Aussehen der Rauchwarenumhüllungspapiere oder entsprechen nicht gesetzlichen Regelungen. Ziel der vorliegenden Erfindung ist es somit, die oben geschilderten Probleme zu überwinden und ein Rauchwarenumhüllungsmaterial bereitzustellen, das bei unveränderter Luftdurchlässigkeit eine Reduzierung des Kohlenmonoxidgehaltes der Rauchinhaltsstoffe ermöglicht.Further, the CO reduction catalysts used in the prior art change the appearance of the tobacco wrapper papers or do not conform to legal regulations. The aim of the present invention is thus to overcome the above-mentioned problems and to provide a tobacco product wrapping material, which allows a reduction of the carbon monoxide content of the smoke ingredients with unchanged air permeability.
Überraschenderweise haben die Erfinder der vorliegenden Erfindung festgestellt, das die obige Aufgabe durch ein Rauchwarenumhüllungsmaterial gelöst wird, das als Füllstoff zwei in der Teilchengröße und Menge unterschiedliche Calciumcarbonate beinhaltet.Surprisingly, the inventors of the present invention have found that the above object is achieved by a smoking article wrapping material containing as filler two calcium carbonate different in particle size and amount.
Gegenstand eines Aspekts der vorliegenden Erfindung ist somit ein Rauchwarenumhüllungsmaterial, das als Füllstoff Calciumcarbonate unterschiedlicher Teilchengröße enthält, wobei eines der Calciumcarbonate eine Teilchengröße von 0,1 bis 2 μm aufweist und in einer Menge von 51 -99 %, bezogen auf den Gesamtgehalt an Calciumcarbonatfüllstoffen, enthalten ist und ein anderes Calciumcarbonat eine Teilchengröße von 3,5 -10 μm aufweist und in einer Menge von 1 - 49 %, bezogen auf den Gesamtgehalt an Calciumcarbonatfüllstoffen, enthalten ist.Thus, in one aspect of the present invention, there is provided a tobacco ware wrapping material containing calcium carbonate of different particle size as a filler, one of the calcium carbonates having a particle size of 0.1 to 2 μm and an amount of 51 to 99%, based on the total content of calcium carbonate fillers. and another calcium carbonate has a particle size of 3.5-10 microns and is contained in an amount of 1-49% based on the total content of calcium carbonate fillers.

Des weiteren können dem erfindungsgemäßen Rauchwarenumhüllungsmaterial optional weitere Füllstoffe wie Calciumcarbonat einer anderen Teilchengröße, Titandioxid, Magnesiumoxid, Talkum oder Kaolin zugesetzt werden.The calcium carbonates used according to the invention are calcium carbonate having a particle size of from 0.1 to 2.0 μm, preferably from 0.3 to 1 μm, in an amount of from 51 to 99%, preferably from 70 to 95%, based on the Total amount of the fillers, as well as a second calcium carbonate having a particle size of 3.5 -10 .mu.m, preferably 4 to 6 .mu.m, in an amount of 1 -49%, preferably 5 -30%, based on the total amount of fillers , is included. Furthermore, further fillers such as calcium carbonate of a different particle size, titanium dioxide, magnesium oxide, talc or kaolin may optionally be added to the tobacco product wrapping material according to the invention.
Die Differenzierung der Teilchengröße des Calciumcarbonates bewirkt beim Verbrennungsprozess des Rauchwarenumhüllungsmaterials in Kombination mit einer daraus gefertigten Rauchware, vorzugsweise Zigarette, die Bildung eines äußeren Ascheschlauches, der eine in besonderer Weise poröse Struktur aufzeigt.The differentiation of the particle size of the calcium carbonate causes in the combustion process of the tobacco product wrapping material in combination with a manufactured therefrom smoking product, preferably cigarette, the formation of an outer ash tube, which shows a particularly porous structure.
Die poröse Struktur des verglimmten Rauchwarenumhüllungspapiers wird im wesentlichen durch die erfindungsgemäße Kombination von zwei in der Teilchengröße und Menge unterschiedlichen Calciumcarbonate und die Gesamtmenge des Calciumcarbonates und nur unwesentlich durch die Höhe der Luftdurchlässigkeit des Rauchwarenumhüllungsmaterials bestimmt.The porous structure of the smoldering tobacco wrapper paper is essentially determined by the inventive combination of two different in particle size and amount calcium carbonates and the total amount of calcium carbonate and only slightly by the level of air permeability of the tobacco product wrapping material.
Ferner kann das erfindungsgemäße Rauchwarenumhüllungsmaterial optional eine die Brenngeschwindigkeit verzögernde Substanz und/oder eine die Brenngeschwindigkeit beschleunigende Substanz enthalten.Further, the tobacco product wrapping material of the present invention may optionally include a burning rate retarding substance and / or a burning rate accelerating substance.
Als die Brenngeschwindigkeit verzögernde Substanz lässt sich erfindungsgemäß Di- natriumhydrogenphosphat nennen.According to the invention, the substance delaying the burning rate can be called diisodium hydrogenphosphate.
