Definitions
- the invention relates to a filter mouthpiece for a smoking product, in particular a cigarette, with a filter strand surrounded by a mouthpiece wrap layer with an essentially circular, oval or lenticular cross-section, in which the smoke flowing in the direction of the filter longitudinal axis is deflected from the direction of flow in the region of the mouth-side filter strand end.
- Filter mouthpieces of the aforementioned type are known from European laid-open specification No. 0025327, FIG. 5, and from European laid-open specification No. 0039591.
- the smoke arriving at the mouth end of the filter strand is deflected by flow obstacles.
- the known embodiments have the disadvantage that, in any case, at least one additional work step is required after the usual steps in the manufacture of cigarettes in order to attach the flow obstacle to the smoke exit surface.
- the invention is directed to a filter mouthpiece of the type mentioned at the outset which can be processed in the course of conventional cigarette production at unchanged high production speeds, the special measures for filter modification being able to take place before the tobacco and filter strands are joined together.
- a filter mouthpiece in which the mouthpiece wrapping ends on the mouth side at a distance from the end of the filter strand and the protruding end of the filter strand is tapered in the direction of the flow of smoke, the smoke flowing out from the end of the protruding filter at an angle to the longitudinal axis of the cigarette.
- the smoke stream is deflected from the longer part of the filter strand during smoking and emerges approximately perpendicular to the oblique surfaces, with the desired positive taste effect, in particular in the case of so-called light cigarettes sets.
- the delimiting surfaces are curved; with a suitable shape, the smoke flow will normally find the shortest way out of the filter, i.e. Flowing out obliquely with respect to the longitudinal axis of the cigarette, and not the longer way in the direction of the longitudinal axis of the filter.
- Filter tips of the invention can generally be processed in conventional cigarette machines.
- the cigarettes are manufactured in such a way that the tobacco strands covered with paper are attached to the two ends of a double filter; The double filter is then cut vertically and in the middle with a rapidly rotating knife.
- the protruding filter strand end of the filter mouthpiece of the invention is preferably substantially conical or frustoconical, spherical, dome-shaped or spherical segment-shaped, in the manner of an ellipsoid or ellipsoid segment or stepped.
- the angle ⁇ is 20-45 °. With frustoconical filter ends, however, angles ⁇ of up to 75 ° are also possible.
- the invention is not only applicable to filters with air impermeable but surprisingly also to those with air permeable tip paper, i.e. applicable to so-called side-ventilated filters.
- the filter mouthpiece according to FIG. 1 comprises a filter strand 2 placed on a tobacco rod 1, which is wrapped in a mouthpiece covering paper 3. If necessary, a connecting sheet, not shown, can also be provided for connecting the filter and tobacco rod.
- the filter strand 2 is cut vertically at its end adjacent to the tobacco strand 1 in the usual way. At the mouth end of the filter rod end, the delimiting surfaces 4 of the filter rod 2 form an angle a of e.g. 45 ° with the formation of a cone 9. Since the filter strand 2 is made of fibers customary for cigarettes, e.g. Cellulose acetate fibers or foamed, open-pored filter material, there are no problems due to the formation of the mouth end of the filter strand, e.g. regarding the leakage of filter material.
- FIGS. 2-6 relate to other configurations of the filter mouthpieces of the invention, the mouth-side filter strand end of which also protrudes beyond the mouthpiece covering paper 3.
- the filter strand 2 can be configured on the mouth side in the form of a truncated cone 10, a hemisphere 11, a hemisphere segment 12 or in the form of tapered steps 13.
- the preferred directions of smoke outlet are marked with arrows.
- the embodiment according to FIG. 6 is particularly suitable for cigarettes with an oval or lenticular cross section, because in this case the smoke e.g. according to the preferred direction of smoke flow according to the arrows according to FIG. can be directed into the cheek cavities of the smoker.
- the smoke exit surfaces of the mouth-side filter strand end of the embodiments according to FIGS. 1-7 can also be partially airtightly sealed; the suitable positions for this are e.g. 7 with the reference numeral 14.
- Cigarettes with mouthpieces of the type shown here have a significantly fuller smoky taste than those with conventional filter mouthpieces. In addition, the sharpness and scratchiness of the smoke are reduced.
- the filter effect of filter mouthpieces modified according to the invention is the same as that of conventional filter mouthpieces. No changes in the composition of the smoke components were found.

Description
Die Erfindung betrifft ein Filtermundstück für ein Rauchprodukt, insbesondere eine Cigarette, mit einem von einer Mundstückwickellage umgebenen Filterstrang mit im wesentlichen kreisförmigem, ovalem oder linsenförmigem Querschnitt, in dem der in Richtung der Filterlängsachse strömende Rauch im Bereich des mundseitigen Filterstrangendes aus der Strömungsrichtung abgelenkt ist.The invention relates to a filter mouthpiece for a smoking product, in particular a cigarette, with a filter strand surrounded by a mouthpiece wrap layer with an essentially circular, oval or lenticular cross-section, in which the smoke flowing in the direction of the filter longitudinal axis is deflected from the direction of flow in the region of the mouth-side filter strand end.
Filtermundstücke der vorgenannten Art sind aus der europäischen Offenlegungsschrift Nr. 0025327, Fig. 5, sowie aus der europäischen Offenlegungsschrift Nr. 0039591 bekannt. Bei den bekannten Ausführungsformen wird der am mundseitigen Ende des Filterstrangesankommende Rauch durch Strömungshindernisse abgelenkt.Filter mouthpieces of the aforementioned type are known from European laid-open specification No. 0025327, FIG. 5, and from European laid-open specification No. 0039591. In the known embodiments, the smoke arriving at the mouth end of the filter strand is deflected by flow obstacles.
Die Rauchkonzentration in bestimmten Filterbereichen führt zu einer positiven Beeinflussung des Geschmacks des auftretenden Rauchs. Die bekannten Ausführungsformen weisen allerdings den Nachteil auf, dass in jedem Falle im Anschluss an die üblichen Schritte einer Cigaretternherstellung mindestens ein zusätzlicher Arbeitsschritt erforderlich ist, um an der Rauchaustrittsfläche das Strömungshindemis anzubringen.The smoke concentration in certain filter areas leads to a positive influence on the taste of the smoke that occurs. However, the known embodiments have the disadvantage that, in any case, at least one additional work step is required after the usual steps in the manufacture of cigarettes in order to attach the flow obstacle to the smoke exit surface.
Die Erfindung ist auf ein Filtermundstück der eingangs genannten Art gerichtet, das im Verlauf einer üblichen Cigarettenherstellung bei unverändert hohen Produktionsgeschwindigkeiten verarbeitet werden kann, wobei die besonderen Massnahmen der Filtermodifikation vor dem Zusammenfügen von Tabak- und Filterstrang erfolgen können.The invention is directed to a filter mouthpiece of the type mentioned at the outset which can be processed in the course of conventional cigarette production at unchanged high production speeds, the special measures for filter modification being able to take place before the tobacco and filter strands are joined together.
Diese Aufgabe wird erfindungsgemäss durch ein Filtermundstück gelöst, bei dem die Mundstückwickellage mundseitig im Abstand vor dem Filterstrangende endet und das überstehende Filterstrangende sich in Rauchströmungsrichtung verjüngend ausgebildet ist, wobei der Rauch aus dem überstehenden Filterstrangende schräg zur Cigarettenlängsachse ausströmt.This object is achieved according to the invention by a filter mouthpiece in which the mouthpiece wrapping ends on the mouth side at a distance from the end of the filter strand and the protruding end of the filter strand is tapered in the direction of the flow of smoke, the smoke flowing out from the end of the protruding filter at an angle to the longitudinal axis of the cigarette.
Soweit das mundseitige Fifterstrangende des Filtermundstückes der Erfindung von schrägen, ebenen Flächen gebildet ist, wird beim Rauchen der Rauchstrom aus dem längeren Teil des Filterstranges abgelenkt und tritt etwa senkrecht zu den schrägen Flächen aus, wobei sich, insbesondere bei sogenannten Leichtcigaretten, der gewünschte positive Geschmackseffekt einstellt. Entsprechendes gilt für den Fall, dass die begrenzenden Flächen gekrümmt sind; bei geeigneter Formgebung wird sich der Rauchstrom normalerweise den kürzesten Weg aus dem Filter suchen, d.h. schräg in Bezug zur Cigarettenlängsachse ausströmen, und nicht den längeren Weg in Richtung der Filterlängsachse.As far as the mouth end of the filter mouthpiece of the filter mouthpiece of the invention is formed by oblique, flat surfaces, the smoke stream is deflected from the longer part of the filter strand during smoking and emerges approximately perpendicular to the oblique surfaces, with the desired positive taste effect, in particular in the case of so-called light cigarettes sets. The same applies in the event that the delimiting surfaces are curved; with a suitable shape, the smoke flow will normally find the shortest way out of the filter, i.e. Flowing out obliquely with respect to the longitudinal axis of the cigarette, and not the longer way in the direction of the longitudinal axis of the filter.
Filtermundstücke der Erfindung können im allgemeinen in üblichen Cigarettenmaschinen verarbeitet werden. In modernen Cigarettenmaschinen werden die Cigaretten in der Weise hergestellt, dass die mit Papierumhüllten Tabakstränge an den beiden Enden eines Doppelfilters angebracht werden; der Doppelfilter wird anschliessend mit einem schnell rotierenden Messer senkrecht und in der Mitte durchgeschnitten.Filter tips of the invention can generally be processed in conventional cigarette machines. In modern cigarette machines, the cigarettes are manufactured in such a way that the tobacco strands covered with paper are attached to the two ends of a double filter; The double filter is then cut vertically and in the middle with a rapidly rotating knife.
Die Herstellung von Filtermundstücken mit mehreren Begrenzungsflächen erfordert etwas abweichende Massnahmen; sie ist insbesondere dann sehr einfach, wenn die überstehenden Filterstrangenden an ihrem Ende stumpf ausgebildet sind und ihre Form rotationssymmetrisch in bezug auf die Mittellängsachse der Cigarette ist, z.B. nach Art eines Kegelstumpfes, Kugelsegmentes, Ellipsoidstumpfes oder in stufenförmiger Verjüngung. Es ist dann lediglich erforderlich, in der Mitte eines Doppelfilters eine entsprechende Ausnehmung anzubringen, wonach der Doppelfilter, nach Vereinigung mit den Tabaksträngen, mittig in der Ausnehmung senkrecht durchgeschnitten wird.The manufacture of filter mouthpieces with several boundary surfaces requires somewhat different measures; it is particularly simple if the protruding ends of the filter strands are blunt at their ends and their shape is rotationally symmetrical with respect to the central longitudinal axis of the cigarette, e.g. in the manner of a truncated cone, spherical segment, truncated ellipsoid or in a step-shaped taper. It is then only necessary to make a corresponding recess in the middle of a double filter, after which the double filter, after being combined with the tobacco rods, is cut through vertically in the center of the recess.
Das überstehende Filterstrangende des Filtermundstückes der Erfindung ist vorzugsweise im wesentlichen kegel- oder kegelstumpfförmig, kugel-, kalotten- oder kugelsegmentförmig, nach Art eines Ellipsoids oder Ellipsoidsegmentes oder stufenförmig ausgebildet.The protruding filter strand end of the filter mouthpiece of the invention is preferably substantially conical or frustoconical, spherical, dome-shaped or spherical segment-shaped, in the manner of an ellipsoid or ellipsoid segment or stepped.
Es können jedoch auch mehrere, jeweils schräg zueinander verlaufende ebene und/oder nicht ebene, z.B. sphärisch gekrümmte Flächen vorgesehen sein, z.B. kegelförmig ausgebildete Endflächen mit der Spitze in Strömungsrichtung, d.h. auf den Mund des Rauchers weisend Die begrenzenden Flächen des mundseitigen Filterstranges bilden einen Winkel α von mindestens 5°.However, several planes and / or planes which are each inclined to one another, e.g. spherically curved surfaces may be provided, e.g. conical end faces with the tip in the direction of flow, i.e. Pointing to the smoker's mouth. The delimiting surfaces of the mouth-side filter strand form an angle α of at least 5 °.
Gemäss einer weiteren bevorzugten Ausführungsform der Erfindung beträgt der Winkel α 20-45°. Bei kegelstumpfförmigen Filterenden sind jedoch auch Winkel α bis zu 75° möglich.According to a further preferred embodiment of the invention, the angle α is 20-45 °. With frustoconical filter ends, however, angles α of up to 75 ° are also possible.
Die Erfindung ist nicht nur auf Filter mit luftundurchlässigem, sondern überraschenderweise auch auf solche mit luftdurchlässigem Mundstückbelagpapier, d.h. auf sogenannte seitenventilierte Filter, anwendbar.The invention is not only applicable to filters with air impermeable but surprisingly also to those with air permeable tip paper, i.e. applicable to so-called side-ventilated filters.
Weitere Merkmale der Erfindung ergeben sich ausderfolgenden Beschreibung bevorzugter Ausführungsbeispiele, wobei auf die Zeichnungen Bezug genommen wird. Die Anwendbarkeit des Filtermundstücks der Erfindung ist nicht auf Cigaretten beschränkt; es kann auch beispielsweise bei Cigarillos und dergleichen eingesetzt werden.Further features of the invention will become apparent from the following description of preferred embodiments, reference being made to the drawings. The applicability of the filter mouthpiece of the invention is not limited to cigarettes; it can also be used for example in cigarillos and the like.

Das Filtermundstück gemäss Fig. 1 umfasst einen auf einen Tabakstrang 1 aufgesetzten Filterstrang 2, der von einem Mundstückbelagpapier 3 umhüllt ist. Gegebenenfalls kann zur Verbindung von Filter- und Tabakstrang noch ein nicht gezeigtes Verbindungsblättchen vorgesehen werden. Der Filterstrang 2 ist an seinem an den Tabakstrang 1 angrenzenden Ende in üblicher Weise senkrecht geschnitten. An dem mundseitigen Filterstrangende bilden die begrenzenden Flächen 4 des Filterstranges 2 mit der durch 5 gekennzeichneten Querschnittsebene des Filterstranges einen Winkel a von z.B. 45° unter Ausbildung eines Kegels 9. Da der Filterstrang 2 aus für Cigaretten üblichen Fasern, z.B. Celluloseacetatfasern oder geschäumtem, offenporigem Filtermaterial besteht, ergeben sich durch die Ausbildung des mundseitigen Filterstrangendes keine Probleme, z.B. bezüglich des Austritts von Filtermaterial.The filter mouthpiece according to FIG. 1 comprises a

Wie aus den Zeichnungen ersichtlich, kann der Filterstrang 2 mundseitig in Form eines Kegelstumpfes 10, einer Halbkugel 11, eines Halbkugelsegementes 12 oder in Form von sich verjüngenden Stufen 13 ausgebildet sein. Die bevorzugten Rauchaustrittsrichtungen sind mit Pfeilen gekennnzeichnet.The embodiments according to FIGS. 2-6 relate to other configurations of the filter mouthpieces of the invention, the mouth-side filter strand end of which also protrudes beyond the
Die Ausführungsform gemäss Fig. 6 ist insbesondere für Cigaretten mit ovalem oder linsenförmigem Querschnitt geeignet, weil bei dieser entsprechend der bevorzugten Rauchströmungsrichtung entsprechend den Pfeilen gemäss Fig. 7 der Rauch z.B. in die Wangenhöhlungen des Rauchers geleitet werden kann.The embodiment according to FIG. 6 is particularly suitable for cigarettes with an oval or lenticular cross section, because in this case the smoke e.g. according to the preferred direction of smoke flow according to the arrows according to FIG. can be directed into the cheek cavities of the smoker.
Die Rauchaustrittsflächen des mundseitigen Filterstrangendes der Ausführungsformen gemäss den Fig. 1-7 können auch teilweise luftundurchlässig vesiegelt sein; die hierfür geeigneten Positionen sind z.B. in Fig. 7 mit dem Bezugszeichen 14 versehen.The smoke exit surfaces of the mouth-side filter strand end of the embodiments according to FIGS. 1-7 can also be partially airtightly sealed; the suitable positions for this are e.g. 7 with the
Cigaretten mit Mundstücken der hier gezeigten Art weisen gegenüber solchen mit herkömmlichen Filtermundstücken einen deutlich volleren Rauchgeschmack auf. Zusätzlich werden Schärfe und Kratzigkeit des Rauches vermindert. Die Filterwirkung erfindungsgemäss modifizierter Filtermundstücke ist die gleiche wie bei den herkömmlichen Filtermundstücken. Änderungen der Zusammensetzung der Rauchbestandteile wurden nicht festgestellt.Cigarettes with mouthpieces of the type shown here have a significantly fuller smoky taste than those with conventional filter mouthpieces. In addition, the sharpness and scratchiness of the smoke are reduced. The filter effect of filter mouthpieces modified according to the invention is the same as that of conventional filter mouthpieces. No changes in the composition of the smoke components were found.
