Description

Die Erfindung betrifft eine Zigarettenpapierhülse mit Filter und Tabakaufnahmeraum, der zur Selbstherstellung einer Zigarette mit Tabak füllbar ist.The invention relates to a cigarette paper tube with a filter and tobacco room, for making a cigarette can be filled with tobacco.

Derartige Zigarettenpapierhülsen sind allgemein bekannt (siehe Dokument DE 4206509 A) und im Handel erhältlich. Sie werden in Verbindung mit losem oder auch stab- bzw. patronenartig vorgefertigtem Tabak zur Selbstherstellung von Zigaretten angeboten. Die bekannten Zigarettenpapierhülsen stellen jedoch hinsichtlich Filter und Tabakaufnahmeraum eine konstante, d.h. unveränderbare Größe dar. Dementsprechend liegt der vorliegenden Erfindung die Aufgabe zugrunde, Zigarettenpapierhülsen der eingangs genannten Art bereitzustellen, die hinsichtlich des Filters variabel sind, und zwar mit einfachsten herstellungstechnischen Mitteln.Such cigarette paper tubes are generally known (see document DE 4206509 A) and available in the stores. You will be in touch with loose or also prefabricated tobacco rod or cartridge Homemade cigarettes offered. The well-known However, cigarette paper tubes represent filters and Tobacco intake room a constant, i.e. unchangeable size Accordingly, the present invention is the Task based on cigarette paper tubes of the aforementioned Provide type that is variable in terms of the filter are, with the simplest manufacturing technology Means.

Diese Aufgabe läßt sich durch die kennzeichnenden Merkmale des Anspruchs 1 lösen, wobei vorteilhafte Details der erfindungsgemäßen Ausführung in den Unteransprüchen beschrieben sind.
Die erfindungsgemäße Zigarettenpapierhülse zeichnet sich also durch einen Filter aus, welcher aus wenigstens zwei Filterstücken besteht, wobei das innere, an den Tabakaufnahmeraum angrenzende Filterstück von Zigarettenpapier umhüllt ist, während das äußere Filterstück einen Durchmesser aufweist, der etwa dem Durchmesser vom inneren Filterstück samt Zigarettenpapierumhüllung entspricht, so daß das äußere Filterstück durch ein Mundstückbelagpapier am inneren mit Zigarettenpapier umhüllten Filterstück ohne Ausbildung von Falten am Mundstückbelagpapier gehalten werden kann. Die beiden Filterstücke erlauben sowohl eine Variation der Filterlänge als auch eine Variation der physikalischen und/oder chemischen Eigenschaften des Filters, ohne daß dies mit einem größeren herstellungstechnischen Aufwand im Vergleich zur herkömmlichen Filterzigerettenpapierhülsen-Herstellung verbunden ist. Vorzugsweise ist das äußere Filterstück jedenfalls Teil eines sog. Einsetzfilters, wie er bei der Herstellung herkömmlicher Zigaretten verwendet wird. Der Einsetzfilter wird bei der Herstellung jeweils zwischen zwei voneinander separierten Zigarettenpapierhülsen mit jeweils innerem Filterstück eingesetzt und nach Einschlag mit Mundstückbelagpapier hälftig voneinander getrennt. Die inneren Filterstücke sind ebenfalls jeweils Teil eines sog. Doppelfilters, wie er zur Herstellung herkömmlicher Zigarettenpapierhülsen mit Filter verwendet wird.
This object can be achieved by the characterizing features of claim 1, advantageous details of the embodiment according to the invention being described in the subclaims.
The cigarette paper tube according to the invention is thus characterized by a filter which consists of at least two filter pieces, the inner filter piece adjacent to the tobacco receiving space being encased by cigarette paper, while the outer filter piece has a diameter which corresponds approximately to the diameter of the inner filter piece including cigarette paper wrapping , so that the outer filter piece can be held by a mouthpiece covering paper on the inner filter piece covered with cigarette paper without forming wrinkles on the mouthpiece covering paper. The two filter pieces allow both a variation of the filter length and a variation of the physical and / or chemical properties of the filter, without this being associated with a greater manufacturing outlay in comparison to conventional filter cigarette paper tube manufacture. In any case, the outer filter piece is preferably part of a so-called insert filter, as is used in the production of conventional cigarettes. The insert filter is inserted between two separate cigarette paper tubes, each with an inner filter piece, and is cut in half after being wrapped with tip paper. The inner filter pieces are also part of a so-called double filter, as used to manufacture conventional cigarette paper tubes with filters.

Abhängig von der Länge des Einsetzfilters läßt sich die Länge des Filters einer jeden Zigarettenpapierhülse einstellen, ohne daß Einfluß auf die Länge des Tabakaufnahmeraums genommen wird. Durch diese Maßnahme läßt sich auch in äußerst einfacher Weise das Rauchverhalten der mit Tabak gefüllten Zigarettenpapierhülse variieren.Depending on the length of the insert filter, the length can be adjust the filter of each cigarette paper tube, without affecting the length of the tobacco room becomes. This measure can also be extremely simple The smoking behavior of the cigarette paper tube filled with tobacco vary.

Die beiden Filterstücke können jeweils gleichermaßen oder voneinander verschieden ausgebildet sein. Im letztgenannten Fall kann das eine Filterstück z.B. ein Acetatkohlefilter und das andere Filterstück ein Acetat- bzw. Kreppfilter sein.The two filter pieces can each be the same or be different from each other. In the latter In this case, a filter piece e.g. an acetate carbon filter and the other filter piece is an acetate or crepe filter.

Zur Beimischung von Außenluft ist das Mundstückbelagpapier vorzugsweise hochporös, insbesondere mikrogelasert, wobei die Füllung des äußeren Filterstücks ebenfalls hochporös, z.B. mikrogelasert, ist, so daß im Bereich des äußeren Filterstücks eine vorbestimmte Menge von Außen- bzw. Nebenluft einziehbar ist. Damit lassen sich die allgemein bekannten Effekte der Zumischung von kühler Außenluft erzielen. Um diesen Effekt zu begünstigen, ist das Mundstückbelagpapier zumindest im Bereich des äußeren Filterstücks nur teilflächig, insbesondere längs axialer und/oder sich über den Umfang erstreckender und axial voneinander beabstandeter Streifen mit der Umhüllung des äußeren Filterstücks verklebt. Auch eine punktweise Verklebung ist denkbar. Auf jeden Fall muß beachtet werden, daß ein genügend großer hochporöser oder perforierter Bereich vorhanden ist, um im heißen Rauch ausreichend kühle Außenluft zumischen zu können.The tip of the tip is to add outside air preferably highly porous, in particular micro-lasered, the Filling of the outer filter piece also highly porous, e.g. is micro-lasered, so that in the area of the outer filter piece a predetermined amount of outside or secondary air can be drawn in is. This allows the well-known Achieve effects of adding cool outside air. To this The mouthpiece covering paper is to promote the effect at least in the area of the outer filter piece only partially, in particular along the axial and / or over the Extending circumferentially and axially spaced apart Stripes glued to the outer filter piece. Point-by-point bonding is also conceivable. Definitely must be noted that a sufficiently large or highly porous perforated area is present to suffice in hot smoke to be able to mix in cool outside air.

Die beiden Filterstücke liegen in axialer Richtung vorzugsweise dicht aneinander; alternativ können sie auch axial voneinander beabstandet sein unter Ausbildung einer sog. Filterkammer. Im Bereich derselben kann das Mundstückbelagpapier gesondert perforiert sein, so daß in diesem Bereich bei jedem Zug dem heißen Rauch ausreichend kühle Außenluft zumischbar ist, wodurch nicht nur eine Abkühlung des Rauchs, sondern auch eine Verdünnung desselben erhielt wird.The two filter pieces are preferably in the axial direction close together; alternatively, they can also be axially apart be spaced to form a so-called filter chamber. In the area of the same, the tip paper can be separately perforated so that in this area with everyone Sufficiently cool outside air can be mixed in with the hot smoke is, whereby not only a cooling of the smoke, but a dilution of the same is also obtained.

Der Doppel- bzw. Mehrfachfilter ist vorzugsweise so eingestellt, daß trotz relativ kurzem Tabakaufnahmeraum das Zug- und Rauchverhalten dem einer herkömmlichen Fabrikzigarette entspricht. Die Tabakfüllung ist vorzugsweise Teil eines vorgefertigten Tabakstrangs, der durch eine äußere Umhüllung formstabil zusammengehalten ist. Der Tabakstrang weist einen Durchmesser auf, welcher nur geringfügig kleiner ist als der Innendurchmesser des Tabakaufnahmeraums der Zigarettenpapierhülse. Die Umhüllung des Tabakstrangs kann entweder hochporös sein, so daß er außerhalb der Zigarettenpapierhülse nicht rauchbar ist; alternativ kann der Tabakstrang auch nach Art einer rauchfertigen Zigarette hergestellt sein. Insofern besteht keine Beschränkung der Variationsmöglichkeiten.The double or multiple filter is preferably set so that despite the relatively short tobacco and smoking behavior that of a conventional factory cigarette equivalent. The tobacco filling is preferably part of one prefabricated tobacco rod through an outer wrapper is held together in a dimensionally stable manner. The tobacco rod has one Diameter, which is only slightly smaller than that Inner diameter of the tobacco-receiving space of the cigarette paper tube. The wrapping of the tobacco rod can either be highly porous be so that it is not outside the cigarette paper tube is smokable; alternatively, the tobacco rod can also be processed according to Art a smokable cigarette. insofar there is no limit to the possible variations.

Bei einem konkreten Ausführungsbeispiel ist der Durchmesser des äußeren Filterstücks etwa 2/10 mm größer als der äußere Durchmesser des mit Zigarettenpapier umhüllten inneren Filterstücks. Dann ist gewährleistet, daß beim Einschlag vom äußeren und inneren Filterstück mit Mundstückbelagpapier dieses im Bereich des äußeren Filterstücks keine Falten wirft.In a specific embodiment, the diameter is of the outer filter piece about 2/10 mm larger than the outer one Diameter of the inner filter piece covered with cigarette paper. Then it is guaranteed that the impact from outer and inner filter piece with mouthpiece covering paper this does not wrinkle in the area of the outer filter piece.

Die oben erwähnte bevorzugte Tabakfüllung ist in Verbindung mit dem Mehrfachfilter vor allem so eingestellt, daß unter Verwendung der erfindungsgemäßen Zigarettenpapierhülse etwa genauso viele Rauchzüge gemacht werden können wie mit einer herkömmlichen Fabrikzigarette.The preferred tobacco filling mentioned above is related with the multiple filter especially set so that under Use of the cigarette paper tube according to the invention, for example as many smoke moves can be made as with one conventional factory cigarette.

Bei einer besonderen Ausführungsform kann zwischen dem äußeren und inneren Filterstück noch ein weiteres Filterstück eingesetzt sein, welches ebenfalls Teil eines sog. Einsetzfilters ist. Diesem Zwischenfilterstück ist vorzugsweise eine klebstoffrei perforierte Zone des Mundstückbelagpapiers zugeordnet. Des weiteren ist das Zwischenfilterstück so dimensioniert, daß ein Zwischenraum zwischen Mundstückbelagpapier und äußerer Umfangsfläche des Zwischenfilterstücks entsteht, insbesondere ein ringförmiger Zwischenraum. Der Mindestabstand zwischen Mundstückbelagpapier und der äußeren Umfangsfläche des Zwischenfilterstücks beträgt etwa 30 µ. 40 µ sollte der Abstand zwischen Mundstückbelagpapier und äußerer Umfangsfläche des Zwischenfilterstücks nicht überschreiten.In a particular embodiment, the outer and inner filter piece yet another filter piece be used, which is also part of a so-called insertion filter is. This intermediate filter piece is preferably a Perforated zone of the mouthpiece covering paper assigned without adhesive. Furthermore, the intermediate filter piece is dimensioned that a gap between the tip paper and outer peripheral surface of the intermediate filter piece arises, in particular an annular space. The minimum distance between the tip paper and the outer peripheral surface the intermediate filter piece is about 30 µ. Should be 40 µ Distance between tip paper and outer peripheral surface of the intermediate filter piece.

Alternativ kann bei einer Duplo-Filter-Ausführung das äußere Filterstück in einer sich über den Umfang erstreckenden Einschnürung versehen sein, um den erwähnten Zwischenraum zu definieren. Die beiden zuletzt genannten Ausführungsformen zeichnen sich durch eine extrem geringe Streuung des Ventilationsgrades im Vergleich mit bekannten Filterkonstruktionen aus. Vor allem werden die sog. Störschicht-Effekte, wie sie bei herkömmlichen Filterkonstruktionen auftreten, vermieden, zumindest erheblich reduziert. Es läßt sich auf diese Weise ein weitgehend gleichbleibender Filter-Ventilationsgrad erreichen.Alternatively, with a Duplo filter version, the outer Filter piece in a constriction extending over the circumference be provided to the space mentioned define. The last two embodiments mentioned are characterized by an extremely low dispersion of the degree of ventilation compared to known filter designs out. Above all, the so-called interference layer effects as they avoided with conventional filter designs, at least significantly reduced. It can be done this way a largely constant degree of filter ventilation to reach.

Das innere Filterstück kann bei einer besonderen Ausführungsform aus einem rauchundurchlässigen Material mit mindestens einem sich axial erstreckenden Rauchkanal ausgebildet sein. Das innere Filterstück bildet demnach eine hohldefinierte Drossel. Bei dieser Ausführungsform sind inneres und äußeres Filterstück vorzugsweise voneinander beabstandet unter Ausbildung einer sog. Filterkammer, in die der erwähnte Rauchkanal mündet. Die Umhüllung bzw. das Mundstückbelagpapier ist im Bereich der Filterkammer lulftdurchlässig. Auf diese Weise läßt sich besonders gut der Druckabfall im Mundstück einstellen, z.B. bei einer Rauchfließgeschwindigkeit von 17,5 cm3/s auf 40 - 200 mm Wassersäule. Trotz dieses Druckabfalls ist gewährleistet, daß durch die Rauchpassage des Mundstücks keine größeren Mengen von Geschmackstoffen verlorengehen. Das Mundstück ist in der beschriebenen Weise einfach herstellbar: Es eignet sich ebenso wie die vorbeschriebenen Ausführungsformen für die Massenproduktion. Wird ein einziger Rauchkanal eingesetzt, so kann dessen Innendurchmesser zwischen 0,5 und 1,5 mm, vorzugsweise zwischen 0,8 und 1,0 mm, betragen.In a special embodiment, the inner filter piece can be formed from a smoke-impermeable material with at least one axially extending smoke channel. The inner filter piece therefore forms a hollow choke. In this embodiment, the inner and outer filter pieces are preferably spaced apart from one another to form a so-called filter chamber into which the aforementioned smoke channel opens. The wrapping or the tip paper is breathable in the area of the filter chamber. In this way, the pressure drop in the mouthpiece can be adjusted particularly well, for example at a smoke flow rate of 17.5 cm 3 / s per 40-200 mm water column. Despite this drop in pressure, it is ensured that no large quantities of flavors are lost through the passage of smoke through the mouthpiece. The mouthpiece is easy to manufacture in the manner described: it is just as suitable for mass production as the embodiments described above. If a single smoke duct is used, its inside diameter can be between 0.5 and 1.5 mm, preferably between 0.8 and 1.0 mm.

Alternativ kann das innere Filterstück als mineralischer Filter ausgebildet sein, um toxische Verbindungen im Rauch auszufiltern, ohne daß der Raucher mit dem entsprechenden Filterstück in Berührung gelangt. Das äußere Filterstück schließt das innere Filterstück nach außen hin ab. Alternatively, the inner filter piece can be used as a mineral filter be trained to filter out toxic compounds in smoke, without the smoker with the appropriate filter piece came into contact. The outer filter piece closes the inner filter piece from the outside.

Die obigen Beispiele lassen erkennen, daß hinsichtlich der Ausbildung und Variation des erfindungsgemäßen Filters kaum Grenzen gesetzt sind.The above examples show that with regard to the Training and variation of the filter according to the invention hardly There are limits.

Nachstehend wird eine erfindungsgemäß ausgebildete Zigarettenpapierhülse mit Duplo-Filter anhand der beigefügten Zeichnung beschrieben. Es zeigen:

the cigarette paper tube according to FIG. 1 in longitudinal section.

Fig. 1 zeigt eine industriell vorgefertigte Zigarettenpapierhülse mit einem Duplo-Filter, bestehend aus einem inneren, unmittelbar an den Tabakaufnahmeraum 11 angrenzenden Filterstück 12 und einem äußeren Filterstück 13, welches durch ein Mundstückbelagpapier 14 in fester Zuordnung zum inneren Filterstück 12 gehalten wird. Entsprechend Fig. 2 ist das innere Filterstück 12 vom Zigarettenpapier 15 umhüllt. Der äußere Durchmesser des äußeren Filterstücks 13 entspricht dem äußeren Durchmesser des inneren Filterstücks 12 samt Zigarettenpapierumhüllung 15, so daß das Mundstückbelagpapier 14 faltenfrei auch um das äußere Filterstück 13 herumgeschlagen werden kann. Das Mundstückbelagpapier steht in herkömmlicher Weise über die innere, den Tabakaufnahmeraum 11 begrenzende Stirnseite des inneren Filterstücks 12 vor.1 shows an industrially prefabricated cigarette paper tube with a duplo filter consisting of an inner, immediately adjacent to the tobacco receiving space 11 filter piece 12 and an outer filter piece 13, which by a Mouthpiece covering paper 14 in a fixed assignment to the inner filter piece 12 is held. 2 is the inner Filter piece 12 wrapped in cigarette paper 15. The outer Diameter of the outer filter piece 13 corresponds to the outer one Diameter of the inner filter piece 12 including the cigarette paper wrapper 15, so that the tip paper 14 crease-free also struck around the outer filter piece 13 can be. The tip paper is in conventional Way over the inner, the tobacco receiving space 11 delimiting Front of the inner filter piece 12 in front.

Wie oben beschrieben, kann das Mundstückbelagpapier im Bereich des äußeren Filterstücks 13 hochporös, z.B. mit einer sich über den Umfang erstreckenden Perforation 16 versehen sein, die sich mit einem entsprechenden hochporösen Bereich der Umhüllung des äußeren Filterstücks 13 deckt. Diese Umhüllung ist in den Figuren nicht mehr dargestellt, da sie allgemein bekannt ist.As described above, the tip paper in the Area of the outer filter piece 13 highly porous, e.g. with a Perforation 16 extending over the circumference be dealing with a corresponding highly porous area the covering of the outer filter piece 13 covers. This Envelope is no longer shown in the figures since it is generally known.

Wie ebenfalls eingangs dargelegt, eignet sich die beschriebene Zigarettenpapierhülse auch in Zuordnung zu einer industriell vorgefertigten formstabilen Tabakportion in Form einer stabartigen Tabakpatrone, die außerhalb der Zigarettenpapierhülse 10 entweder rauchbar oder auch nicht rauchbar ist, auf jeden Fall aus vollständig rauchbarem Material besteht. Ist an einer Stirnseite der Tabakpatrone ein zusätzliches Filterstück angesetzt, läßt sich die beschriebene Filtervariation in entsprechender Weise erhöhen. Man erhält bei der konfektionierten Zigarette auf diese Weise eine Art von Tripel-Filter. Das an der Tabakpatrone angesetzte Filterstück ist vorzugsweise relativ kurz, z.B. nur 5 mm lang. Eine derart ausgebildete Tabakpatrone kann Teil einer sog. Duplo-Tabakportion sein, die insgesamt eine Länge aufweist, die der doppelten Länge des Tabakaufnahmeraums einer zugeordneten Zigarettenpapierhülse entspricht. Die Duplo-Tabakportion enthält entweder mittig ein Doppelfilter, welches vor dem Gebrauch in der Mitte auseinandergeschnitten wird, so daß man zwei Tabakpatronen mit stirnseitig angesetztem Filterstück erhält. Alternativ kann die Duplo-Tabakportion auch jeweils endseitig ein Filterstück aufweisen. Die Herstellung einer Zigarette erfolgt dann durch Aufschieben einer zugeordneten Zigarettenpapierhülse auf beide Enden der Duplo-Tabakportion und anschließender Trennung derselben im Bereich der Stoßstelle der beiden stirnseitig aufgeschobenen Zigarettenpapierhülsen. Im übrigen eignet sich diese Duplo-Tabakportion auch in Zuordnung zu herkömmlichen Zigarettenpapierhülsen mit einfachem Filterstück, welches vorzugsweise etwas kürzer bemessen sein kann als die Filterstücke vergleichbarer herkömmlicher Filterhülsen. As also explained at the beginning, the one described is suitable Cigarette paper tube also in association with an industrial prefabricated dimensionally stable tobacco portion in shape a rod-like tobacco cartridge that is outside the cigarette paper tube 10 either smokable or non-smokable is, in any case, made of completely smokable material consists. Is an additional one on one end of the tobacco cartridge If the filter piece is attached, the filter variation described can be increase accordingly. You get at the assembled cigarette in this way a kind of Triple filter. The filter piece attached to the tobacco cartridge is preferably relatively short, e.g. only 5 mm long. Such a trained tobacco cartridge can be part of a so-called duplo tobacco portion be that has a total length that the double the length of the tobacco storage space associated with one Cigarette paper tube corresponds. The Duplo tobacco serving contains either a double filter in the middle, which before use is cut apart in the middle, so that one two tobacco cartridges with a filter piece attached to the front receives. Alternatively, the Duplo tobacco portion can also be used in each case have a filter piece at the end. The making of a Cigarette then takes place by postponing an assigned one Cigarette paper tube on both ends of the Duplo tobacco serving and then separating them in the area of the joint of the two cigarette paper tubes pushed on at the front. This Duplo portion of tobacco is also suitable also in association with conventional cigarette paper tubes simple filter piece, which is preferably a little shorter can be dimensioned as the filter pieces more comparable conventional Filterhülsen.

Bei den zuletzt genannten Ausführungsformen liegt die Ventilationszone, sofern eine solche vorgesehen ist, vorteilhafterweise im Bereich der an der Tabakpatrone angesetzten Filterstücke.In the last-mentioned embodiments, the ventilation zone is if such is provided, advantageously in the area of the filter pieces attached to the tobacco cartridge.

Die angesetzten Filterstücke können z.B. mit retentionsspezifischen Stoffen, insbesondere mit Aktivkohle und/oder Silicagel versetzt sein. Auch können geschmacksbeeinflussende Wirkstoffe vorgesehen sein, wie Menthol od. dgl. Diese Wirkstoffe können sich z.B. in sog. Mikrokapseln befinden, die durch leichten Fingerdruck von außen her aufbrechbar sind, wobei der Fingerdruck so leicht ist, daß das Mundstückbelagpapier oder Zigarettenpapier dadurch nicht beschädigt oder verknautscht wird. Die vorgenannten Mikrokapseln haben den Vorteil, daß die Wirkstoffe bis zum Gebrauch eingekapselt sind und erst nach dem Aufbrechen wirksam werden. Eine vorzeitige Verflüchtigung der Wirkstoffe ist auf diese Weise ausgeschlossen. Selbstverständlich kann auch das innere Filterstück 12 gemäß der Ausführungsform nach den Figuren 1 und 2 mit derartigen Mikrokapseln versehen sein. Die obige Beschreibung läßt sehr deutlich erkennen, daß sich die erfindungsgemäße Zigarettenpapierhülse durch einen hohen Grad von Freiheitsgraden auszeichnet.The attached filter pieces can e.g. with retention-specific Fabrics, especially with activated carbon and / or silica gel be offset. Also taste-influencing agents be provided, such as menthol or the like. These active substances can e.g. are located in so-called microcapsules that are caused by light finger pressure can be broken from the outside, whereby the finger pressure is so light that the tip paper or cigarette paper is not damaged or wrinkled becomes. The aforementioned microcapsules have the advantage that the active ingredients are encapsulated until use and only take effect after breaking open. An early one This prevents volatilization of the active ingredients. Of course, the inner filter piece can also 12 according to the embodiment according to FIGS. 1 and 2 be provided with such microcapsules. The above Description shows very clearly that the invention Cigarette paper tube by a high degree of Degrees of freedom.

Sämtliche in den Anmeldungsunterlagen offenbarten Merkmale werden als erfindungswesentlich beansprucht, soweit sie einzeln oder in Kombination gegenüber dem Stand der Technik neu sind.All features disclosed in the registration documents are claimed as essential to the invention, insofar as they are individually or new in combination with the prior art are.
