Abstract

The invention relates to a filter cigarette with a tobacco strand enclosed by a cigarette paper, which has a diameter of 5-7 mm, with a smoke yield of at most 1 mg condensate, with a tobacco-side filter element having a relative retention of >90%, with a mouth-side filter element having a relative retention of <10% and with a ventilation zone running in circumferential direction in the encasing and covering paper, which is situated at a distance from the mouth-side filter end, the length of which is at least 1 mm less than that of the mouth-side cork. The nicotine/condensate .10 strand depletion ratio is >=1.0, the overall length of the filter lies between 25-30 mm, the diameter between 5-7 mm and the length of the mouth-side filter cork lies between 13-18 mm.

Description

Die Erfindung betrifft eine dünne Filtercigarette mit einem Durchmesser von etwa 6 mm und einer Länge von 90 bis 100 mm und einer Rauchausbeute von maximal 1 mg Kondensat.The invention relates to a thin filter cigarette with a Diameter of about 6 mm and a length of 90 to 100 mm and a smoke yield of maximum 1 mg condensate.

Dünne Cigaretten dieser erwähnten Abmessungen sind zwar bereits seit vielen Jahren bekannt, allerdings nicht als "leichte" oder "ultra-leichte" Cigaretten sondern mit Stopfdichten und Zugwiderständen sowie Papierporositäten, die keinesfalls die Werte einer heutigen Ultraleicht-Cigarette mit 0,1 mg Nikotin/1 mg Kondensat erreicht. Die Fachwelt hat bislang geglaubt, daß eine Ultraleicht-Cigarette bei kleineren Durchmessern als 8 oder 7 mm gar nicht herstellbar waren.Thin cigarettes of these dimensions are already available known for many years, but not as "light" or "Ultra-light" cigarettes with stuffing densities and draw resistance as well as paper porosities that by no means the values today's ultralight cigarette with 0.1 mg nicotine / 1 mg Condensate reached. So far, experts have believed that a Ultralight cigarette with diameters smaller than 8 or 7 mm were not producible at all.

Aufgabe der Erfindung ist es, eine dünne Filtercigarette mit einem Durchmesser von etwa 6 mm zu schaffen, die aufgrund ihrer Nikotin/Kondensatwerte von 0,1/1 eindeutig als Ultraleicht-Cigarette einzustufen ist und die beim Rauchen eine übliche Zugzahl erreicht.The object of the invention is to use a thin filter cigarette to create a diameter of about 6 mm, due to their Nicotine / condensate values of 0.1 / 1 clearly as an ultralight cigarette is to be classified and the usual for smoking Number of moves reached.

Zur Lösung dieser Aufgabe dienen die Merkmale des Patentanspruchs 1.The features of the claim serve to solve this problem 1.

Durch die Kombination der erfindungsgemäßen Parameter wurde das Ziel auf überraschende Weise erreicht, wobei das Ergebnis für den Raucher äußerst zufriedenstellend ist. Die erfindungsgemäße Cigarette hat eine ansprechende Erscheinungsform, faßt sich gut an und hat auch einen angenehmen Zugwiderstand, der sich beim Rauchen positiv auswirkt.By combining the parameters according to the invention Objective achieved in a surprising way, with the result for the Smoking is extremely satisfactory. The invention Cigarette has an attractive appearance, fits well and also has a pleasant draft resistance, which is the case with Smoking has a positive effect.

Die Erfindung wird im folgenden anhand von Beispielen näher erläutert:

  • Es wurde ein Tabakstrang mit einem Durchmesser von 6,1 mm hergestellt, dessen Stopfdichte 184 mg/cm3 betrug. Die Länge des Tabakstrangs lag bei 70 mm. Der Tabakstrang wurde so gestopft, daß sich ein Zugwiderstand von 100 daPa (deka Pascal) ergab, wobei als Bereich 80 bis 120 daPa zweckmäßig sind. Als Umhüllung für den Tabakstrang wurde ein Cigarettenpapier mit einer Porosität von 24 CORESTA Einheiten (CU) gewählt. Ein geeigneter Bereich wären 8 bis 60 CORESTA Einheiten. Der Tabak hatte einen Anteil von expandiertem Tabak nach dem sogenannten INCOM-Verfahren von 55%. Bei anderen Ausführungen kann der Anteil des expandierten Tabaks zwischen 40 und 100% liegen. Unter "expandiertem" Tabak wird ein Tabak verstanden, der nach dem Expansionsverfahren gemäß der DE-PS 29 03 300, 31 19 330 oder 34 14 625 hergestellt wird. Diese Verfahren werden auch als "INCOM-Verfahren" bezeichnet.
    • The invention is explained in more detail below with the aid of examples:
  • A tobacco rod with a diameter of 6.1 mm was produced, the plug density of which was 184 mg / cm 3 . The length of the tobacco rod was 70 mm. The tobacco rod was stuffed in such a way that a tensile resistance of 100 daPa (deca Pascal) resulted, the range 80 to 120 daPa being expedient. A cigarette paper with a porosity of 24 CORESTA units (CU) was chosen as the wrapper for the tobacco rod. A suitable range would be 8 to 60 CORESTA units. The tobacco had a share of expanded tobacco according to the so-called INCOM method of 55%. In other versions, the proportion of expanded tobacco can be between 40 and 100%. "Expanded" tobacco is understood to mean a tobacco which is produced by the expansion process according to DE-PS 29 03 300, 31 19 330 or 34 14 625. These processes are also referred to as the "INCOM process".

    • An den derart hergestellten Tabakstrang wurde ein Doppelfilter ohne Hohlkammer angesetzt, wobei der strangseitige Filterabschnitt aus Papier und der mundseitige Filterabschnitt aus Celluloseacetat bestand, Die Gesamtlänge des Doppelfilters betrug 27 mm, wobei die Länge des strangseitigen Papierfilters 12 mm und die Länge des mundseitigen Celluloseacetat-Filters 15 mm betrug. Im Abstand von 12 und 13 mm vom mundseitigen Ende des Celluloseacetat-Filters und damit im Abstand von 2 bzw. 3 mm zum Papierfilterabschnitt liefen zwei Reihen von Laserperforierungen durch die Umhüllung, über die Ventilationsluft in den Filter eingeleitet werden kann. Da sich die Perforationslinien im Bereich des Celluloseacetat-Filterabschnitts befinden, strömt die Ventilationsluft nur durch diesen Abschnitt und beeinflußt damit nicht die Strömung durch den Papierabschnitt. Damit wird erreicht, daß die Strömung des Hauptstromrauchs durch den Papierfilterabschnitt verhältnismäßig laminar ist, wobei eine gute Nikotin- und Kondensat-Reduktion erfolgen kann. In dem daran anschließenden Celluloseacetat-Filterabschnitt erfolgt hingegen eine Verwirbelung des Hauptstromrauchs durch die Ventilationsluft, was zu eine deutlichen Geschmacksverbesserung beiträgt.A double filter was attached to the tobacco rod produced in this way attached without a hollow chamber, the strand-side filter section made of paper and the mouth-side filter section made of cellulose acetate existed, The total length of the double filter was 27 mm, the length of the strand-side paper filter being 12 mm and the length of the mouth-side cellulose acetate filter was 15 mm. At a distance of 12 and 13 mm from the mouth end of the cellulose acetate filter and therefore at a distance of 2 or 3 mm to the paper filter section went through two rows of laser perforations the casing through which ventilation air is introduced into the filter can be. Since the perforation lines in the area of Cellulose acetate filter section are located, the ventilation air flows only through this section and thus does not affect the flow through the section of paper. This ensures that the flow of mainstream smoke through the paper filter section is relatively laminar, being a good nicotine and Condensate reduction can take place. In the following In contrast, cellulose acetate filter section is swirled of mainstream smoke from ventilation air what contributes to a significant improvement in taste.

    Durch die Kombination eines Papierfilters mit einem Celluloseacetat-Filter wird ferner erreicht, daß die abgerauchten Cigaretten biologisch wesentlich besser abbaubar sind, da mehr als die Hälfte des zu entsorgenden Cigarettenstummels aus biologisch abbaubarem Material besteht.By combining a paper filter with a cellulose acetate filter it is also achieved that the smoked cigarettes are much more biodegradable because more than half of the cigarette butt to be disposed of from organic degradable material.

    Die einzelnen Parameter der Ausführungsbeispiele werden am Ende der Beschreibung in Form von Tabellen 1 bis 4 wiedergegeben.The individual parameters of the exemplary embodiments are at the end the description in the form of tables 1 to 4.

    Cigarettenrauchen wird zunehmend kritisiert, da insbesondere Nichtraucher sich durch den Rauch und dessen Geruch gestört fühlen. Die erfindungsgemäße Cigarette aus Beispiel 1 weist hier schon deutliche Vorteile gegenüber den meisten handelsüblichen Cigaretten auf, da sie allein aufgrund ihres niedrigen verrauchten Tabakgewichts ca. 40% weniger Nebenstromrauch entstehen läßt und damit zu entsprechend weniger verrauchten Räumen, einem geringeren Geruchseindruck im Raum, sowohl frisch als auch abgestanden, und einem verminderten Geruch der Kleidung, der Haare und der Einrichtungsgegenstände wie Gardinen, Teppiche etc. führt (siehe Tabelle 4).Cigarette smoking is increasingly criticized because in particular Non-smokers are disturbed by the smoke and its smell feel. The cigarette according to the invention from Example 1 points here already clear advantages over most commercially available Cigarettes because they smoke only because of their low Tobacco weight approx. 40% less sidestream smoke lets and thus to correspondingly less smoky rooms, one lower odor impression in the room, both fresh and stale, and a decreased smell of clothing that Hair and furnishings such as curtains, carpets etc. leads (see Table 4).

    Unter Nebenstromrauch wird der Rauch verstanden, der während des Abglimmens der Cigarette aus der Zone vor dem Glutkegel aufsteigt. Verteilt in der Umgebungsluft ist es auch üblich diesen Rauch als "Enviromental Tobacco Smoke" (ETS) oder "second-handsmoke" zu bezeichnen. Um die Rauchmenge zu vergleichen, die von Tabakprodukten beim Verrauchen in die Umgebungsluft abgegeben wird, ist es üblich, eine definierte Anzahl von Mustern der jeweiligen Untersuchunsprobe in einem Raum mit definiertem Volumen und geeigneten Vorrichtungen zur Probennahme für die Messung zu verrauchen. Die Rauchmenge kann z.B. durch Niederschlagung der Rauch partikel auf einer Piezowaage aus einem definierten Probenvolumen bestimmt werden. Die nach diesem Verfahren gemessenen Partikelmassen sind in Tabelle 4 jeweils als Mittelwert aus drei Messungen aufgeführt, um einen Vergleich der von den Ausführungsbeispielen der erfindungsgemäßen Cigaretten erzeugten Rauchmengen mit handelsüblichen Vergleichscigaretten durchzuführen.Side stream smoke is understood to be the smoke that is generated during the The cigarette burns out of the zone in front of the glowing cone. Distributed in the ambient air, it is also common Rauch as "Enviromental Tobacco Smoke" (ETS) or "second-handsmoke" to call. To compare the amount of smoke from Tobacco products released into the ambient air when consumed is, it is common to have a defined number of patterns respective test sample in a room with a defined Volume and suitable sampling devices for the Measurement to consume. The amount of smoke can e.g. by crackdown the smoke particles on a piezo scale from one defined sample volume can be determined. The after this Particle masses measured in Table 4 are each as Average of three measurements listed to compare the of the embodiments of the cigarettes according to the invention produced smoke quantities with standard comparison cigarettes perform.

    Im Anschluß an die Probennahme wurde der Raum durch Probanden eines geschulten Panels (d.i. eine Gruppe) aus Rauchern und Nichtrauchern optisch und geruchlich bewertet. Die Probanden markierten ihren Eindruck anhand des optischen Prüfkriteriums "Verrauchtheit" und des geruchlichen Prüfkriteriums "riecht nach Cigarettenrauch" auf einer Skala von 0 bis 100. Die numerischen Ergebnisse dieser sensorischen Prüfung wurden statistisch ausgewertet, zu Gruppen verdichtet und der folgenden Begriffsskalierung der Prüfkriterien "Verrauchtheit" und "riecht nach Cigarettenrauch" zugeordnet: nicht..., gering..., wenig..., stark..., sehr stark. Die Ergebnisse sind in den Spalten 4 und 5 von Tabelle 4 aufgeführt. Das Ausführungsbeispiel weist quantitativ (-43%) und qualitativ einen geringeren Raucheindruck als handelsübliche Ciaretten auf.Following the sampling, the room was opened by test subjects a trained panel (i.e. a group) of smokers and Non-smokers rated optically and smell. The subjects marked their impression based on the optical test criterion "Smokiness" and the olfactory test criterion "smells like Cigarette smoke "on a scale from 0 to 100. The numerical Results of this sensory test were statistical evaluated, summarized into groups and the following scaling of terms the test criteria "smokiness" and "smells Cigarette smoke "assigned: not ..., low ..., little ..., strong ..., very strong. The results are in columns 4 and 5 listed in Table 4. The embodiment shows quantitatively (-43%) and qualitatively a lower smoke impression as commercially available ciarettes.

    Eine weitere Verbesserung wird erzielt, wenn der Tabakstrang aus Beispiel 1 mit Spezialpapieren, wie sie z.B. von der Fa. Ecusta, Pisgah Forest, NC, U.S.A., zu beziehen sind, umhüllt wird. Die Papiere können in unterschiedlichen Leistungsstufen (Papiere NS1 bis NS3 mit zunehmendem Flächengewicht) eingesetzt werden. Mögliche Ausführungen sind die Beispiele 2a bis 2c, wobei es vom Einsatzgebiet abhängt, ob der Anwender ein Papier geringerer Wirksamkeit wie NS1 wählt, das sich optisch und in der Verfahrbarkeit nicht von Standardpapieren unterscheidet, oder sich für Papiere mit höherer Leistungsfähigkeit entscheidet, die mit zunehmendem Flächengewicht dem Konsumenten auch optisch (dicker, weißer) signalisieren, daß ein Spezialpapier verwendet wird. Durch die Beispiele 2a-c wird der optische Raucheindruck deutlich verringert (siehe Tabelle 4). Geschmacklich werden die Beispiele im Vergleich zu Beispiel 1 von Experten und den Probanden des Rauchpanels als gleichwertig bewertet und im Falle des Beispiels 2a als voller und aromatischer vorgezogen.Another improvement is achieved when the tobacco rod is out Example 1 with special papers, e.g. from Ecusta, Pisgah Forest, NC, U.S.A. The Papers can be of different performance levels (papers NS1 up to NS3 with increasing basis weight). Possible designs are examples 2a to 2c, it being from Area of use depends on whether the user is a paper less Efficacy like NS1 chooses, which is optically and in the movability no different from standard papers, or for Decides papers with higher performance that with increasing weight per unit area also visually (thicker, white) signal that special paper is being used. Examples 2a-c illustrate the visual impression of smoke reduced (see Table 4). The examples are tasty compared to example 1 by experts and the subjects of the Smoke panels rated as equivalent and in the case of the example 2a preferred as full and aromatic.

    Auch der Geruch des Rauches wird für die Beispiele 2a-c in seiner Intensität etwas geringer als der von handelsüblichen Vergleichscigaretten empfunden. Eine weitere Verbesserung ist möglich, indem auf eine zweite Lage der Strangumhüllung Aromen aufgebracht werden, die den Geruch des Rauches positiv beeinflussen, wie dies beispielsweise in der Patentschrift DE 42 44 467 beschrieben ist. Die hiernach hergestellten Anwendungsbeispiele 3a und 3b (wobei Tabakstrang, Filter und die physikalischen und analytischen Daten dem Beispiel 1 entsprechen) zeigen eine signifikante Verminderung in dem Bewertungs-Prüfkriterium "riecht nach Cigarettenrauch" (siehe Tabelle 4).The smell of smoke is also used in Examples 2a-c Intensity somewhat lower than that of standard comparative cigarettes felt. Another improvement is possible by adding flavors to a second layer of the strand wrapper that positively affect the smell of smoke, like this is described for example in the patent specification DE 42 44 467. The application examples 3a and 3b produced according to this (where String of tobacco, filters and the physical and analytical data correspond to Example 1) show a significant reduction in the evaluation test criterion "smells of cigarette smoke" (see table 4).

    Eine weitere Möglichkeit, die quantitative Rauchmenge zu verringern wurde im Beispiel 4 realisiert, indem die Tabakmischung aus Beispiel 1 zu 100% expandiert wurde. Damit wird ein Tabakgewicht unter 300mg erreicht und eine Reduzierung der Partikelmasse um fast 80% gegenüber handelsüblichen Cigaretten. Auch gegenüber einer formatgleichen Cigarette, wie in Beispiel 1 beschrieben, wird eine Reduzierung von über 60% erzielt.Another way to reduce the quantitative amount of smoke was realized in example 4 by the tobacco mixture was expanded to 100% from Example 1. It becomes a tobacco weight reached below 300mg and a reduction in particle mass by almost 80% compared to commercially available cigarettes. Also opposite a cigarette of the same format as described in Example 1, a reduction of over 60% is achieved.

    In einigen Märkten (u.a. Japan, Korea und Ungarn) bevorzugen die Raucher Cigaretten, die Aktivkohle enthalten. Die Aktivkohle wird üblichweise in das tabakseitige Filterelement eingebracht. Im Vergleich zu Cigaretten ohne Aktivkohle werden diese Produkte von Experten übereinstimmend als milder und weicher bezeichnet. Dies beruht auf der Fähigkeit der Aktivkohle, zum Zeitpunkt, während der Rauch den Filter durchströmt, Substanzen der Gasphase, wie z.B Acrolein oder Acetaldehyd, zu adsorbieren. In zwei weiteren Ausführungen wurde bei der in Beispiel 1 beschriebenen Cigarette der stangseitige, aus Papier gefertigte Filterstöpsel mit Aktivkohle bis zu einem Gewichtsanteil von 50% beaufschlagt. Das Aufbringen der Aktivkohle kann prinzipiell auf zwei Wegen erfolgen:In some markets (including Japan, Korea and Hungary) they prefer Smoking cigarettes containing activated carbon. The activated carbon will Usually introduced into the tobacco filter element. in the These products are compared to cigarettes without activated carbon Experts consistently call it milder and softer. This relies on the ability of activated carbon at the time while the smoke flows through the filter, substances of the gas phase, such as e.g. acrolein or acetaldehyde. In two more Comments were made on the cigarette described in Example 1 the rod-side filter plug made of paper with Activated carbon applied up to a weight percentage of 50%. The There are two main ways of applying the activated carbon respectively:

    Erstens durch Aufstreuen der Aktivkohle während der Fertigung des Papierbasisstabes für den Doppelfilter; für eine gleichmäßigere Verteilung der Partikel können zusätzlich Bindemittel oder Haftmittel verwendet werden.First, by sprinkling the activated carbon during the manufacture of the Paper base rod for the double filter; for a more even Distribution of the particles can additionally binders or Adhesives are used.

    Zweitens durch Einbringen sehr fein zerkleinerter Aktivkohlepartikel während des Papierherstellprozesses, was zu einer äußerst gleichmäßigen Verteilung der Partikel und einer sehr effektiven Nutzung (bezogen auf die eingesetzte Gewichtsmenge) des zur Verfügung stehenden Porenvolumens führt.Secondly, by introducing very finely crushed activated carbon particles during the paper making process, resulting in a extremely even distribution of particles and a very effective use (based on the amount of weight used) of the available pore volume.

    In einer anderen Ausführung wurden 30mg Aktivkohle nach dem ersten Verfahren aufgebracht und eine Reduzierung der oben genannten Substanzen der Gasphase von 50% erreicht. Bringt man die gleiche Menge an Aktivkohle nach dem zweiten Verfahren auf, so wird eine Absenkung (bezogen auf Beispiel 1) von 90% erreicht.
