Description

Fi I terpatrone für Rauchgeräte Filter cartridge for smoking devices
Die Erfindung betrifft eine Fi lterpatrone für Rauchgeräte, wie Tabakpfeifen, Zigaretten- und Zigarrenspitzen, welche aus einem spiralförmig ausgebi ldeten Kern und aus einem porösen Werkstoff und einer diesen umgebenden Hülse besteht.The invention relates to a filter cartridge for smoking devices, such as tobacco pipes, cigarette and cigar tips, which consists of a spirally formed core and a porous material and a sleeve surrounding it.
Fi I terpatronen der in Betracht kommenden Art sind in den unterschiedl ichsten Ausführungsformen bekanntgeworden. Be¬ grenzt wirksame Fi lter für Rauchgeräte enthalten in einer rauchdurchströmten Hülse Akti kohlestückchen, da Aktivkohle in besonderem Maße geeignet ist, die unerwünschten, im Tabakrauch enthaltene Bestandtei le, wie Nikotin, Teer¬ desti l late und andere Substanzen, wei testgehend zu adsorbie¬ ren. Fi I terpatronen dieser Art haben verschiedene Nach¬ tei le; ihre Wirksamkeit hat Grenzen und ihre Kosten sind relativ hoch.Filter cartridges of the type in question have become known in the most varied of embodiments. Limited effective filters for smoking devices contain pieces of activated carbon in a smoke-flowed sleeve, since activated carbon is particularly suitable for adsorbing the undesired constituents contained in tobacco smoke, such as nicotine, tar distillate and other substances Filter cartridges of this type have various disadvantages; there are limits to their effectiveness and their costs are relatively high.
Aus den Unterlagen des DE-GM 17 60 179 ist ein Zigaretten- Fi l ermundstück für Tabakrauch bekanntgeworden, welches aus einer starkwandi gen Hülse aus saugfäh i gern Mater i aI besteht, in deren inneren Hohlraum sich eine Spirale be¬ findet, die aus einem Kernstab und einem auf diesen spiral¬ förmig aufgewickelten Band besteht. Ziel und Zweck der im inneren Hohlraum befindl ichen Spirale ist, daß der Rauch den Fi lter längs eines etwas längeren Weges durchströmt, als wenn er diesen auf geradem Wege in axialer Richtung durch¬ strömen würde. Durch die Spirale wird der Tabakrauch an der Innenwand der saugfähigen Fi lterhülse entlanggeführt, wobei die unerwünschten Rauchbestandtei le adsorbiert werden. Fi ltermundstücke dieser Art haben den Nachtei l , nur eine ungenügende Fi lterung bzw. Adsorption der aus dem Rauch her¬ auszufi lternden Bestandtei le zu bewirken.From the documents of DE-GM 17 60 179 a cigarette fi l mouthpiece for tobacco smoke has become known, which consists of a thick-walled sleeve made of absorbent material, in the inner cavity of which there is a spiral consisting of a Core rod and a spiral wound on this consists. The aim and purpose of the spiral located in the inner cavity is for the smoke to flow through the filter along a somewhat longer path than if it were to flow through it in a straight path in the axial direction. The tobacco smoke is guided along the inner wall of the absorbent fi lter sleeve by the spiral, the unwanted smoke constituents being adsorbed. Filter mouthpieces of this type have the disadvantage of only one to cause insufficient filtering or adsorption of the constituents to be filtered out of the smoke.
Ein ähnl iches Zigaretten-Fi ltermundstück ist Gegenstand des DE-GM 16 92 707. Bei diesem ist ein aus porösem Fi ltermaterial bestehender Strang mit krei sförmi gern Quer¬ schnitt mit einem spiralförmig angeordneten Rauchkanal mit einer Papierhül le versehen. Von diesem Strang werden die Zigaretten-Fi ltermundstücke in gewünschter Länge abgetrennt. Der poröse Fi lterstrang besteht aus elasti¬ schem Werkstoff . Die Fi lterwirkung eines solchen Fi lters ist gleichgfal ls ungenügend und daher für die Praxis unbrauchbar .A similar cigarette fi lter mouthpiece is the subject of DE-GM 16 92 707. In this, a strand consisting of porous fi lter material is provided with a circular cross section with a spirally arranged smoke channel with a paper sleeve. The cigarette mouthpieces of the desired length are separated from this strand. The porous filter strand consists of elastic material. The filter effect of such a filter is likewise insufficient and therefore unusable in practice.
Schl ießl ich ist aus der US-PS 41 35 523 ein Fi lterelement für Zigaretten-Mundstücke bekanntgeworden, welches ähn¬ l ich den zuvor beschriebenen Fi ltermundstücken ausgebi ldet ist. Bei diesem befindet sich jedoch an einem Ende eine den ganzen Querschnitt ausfül lende Scheibe, durch welche der Tabakrauch nach Durchströmen des spiralförmigen Rauch¬ kanals hindurchtreten sol l. Der eigentl iche Fi lter besteht aus Cel I u loseacetat und ist von einem porösen Papier um¬ geben. Die Fi lterwirkung auch dieses Fi lters ist ungenügend, insbesondere angesichts der erhöhten Anforderungen an die Adsorptionsfähigkeit solcher Fi lter in heutiger Zeit.Finally, US Pat. No. 4,135,523 has disclosed a filter element for cigarette mouthpieces which is designed similarly to the filter mouthpieces described above. In this case, however, there is a disc that fills the entire cross section at one end, through which the tobacco smoke should pass after flowing through the spiral smoke channel. The actual filter consists of cellulose acetate and is surrounded by a porous paper. The filter effect of this filter is also insufficient, especially in view of the increased requirements for the adsorption capacity of such filters today.
Die Unbrauchbarkei t al ler vorbekannten Fi lter ergibt sich vor al lem daraus, daß kein einziger von ihnen in der Praxis Anwendung gefunden hat.The uselessness of all known filters arises above all from the fact that none of them have been used in practice.
Der Erfindung l iegt die Aufgabe zugrunde, eine Fi lter¬ patrone für Rauchgeräte zu schaffen, welche in besonderem Maße geeignet ist, die an solche Fi lter gestel lten Anfor- derungen zu erfül len, wobei -der Fi lter einen kleinstmög- l ichen Raum einnehmen sol l , ohne daß jedoch dadurch die Leistungsfähigkeit des Fi lters beeinträchtigt ist. Ins¬ besondere sol l es die Fi lterkonstruktion erlauben, zu einem berechenbaren Ergebnis zu gelangen, so daß dadurch die die Wirksamkeit des Fi lters beeinflussenden Faktoren entsprechend festlegbar sind.The invention is based on the object of creating a filter cartridge for smoking devices which is particularly suitable and meets the requirements made of such filters. The filter should take up the smallest possible space without, however, impairing the performance of the filter. In particular, the filter construction should allow a calculable result to be achieved, so that the factors influencing the effectiveness of the filter can be determined accordingly.
Zur Lösung dieser Aufgabe wird gemäß der Erfindung vorge¬ schlagen, die in Betracht kommenden Fi lterpatronen in der Weise auszubi lden, daß der mehrgängige, den zentralen Kern bi ldende Schneckenkörper aus einer porösen adsorptions¬ fähigen organischen Masse aus eiweißhaltiger Stärke, welcher gegebenenfal ls zusätzl ich ein organisches Binde¬ mittel zugesetzt sein kann, besteht, welche gegebenenfal ls einen Antei l an Aktivkohleparti eln enthält, und daß der Schneckenkörper an seiner Oberfläche mit Aktivkohlepartikeln beschichtet ist.To achieve this object, it is proposed according to the invention to design the filter cartridges in question in such a way that the multi-start screw body forming the central core is made of a porous adsorbable organic mass of protein-containing starch, which may be additional I can be added an organic binder, which may contain a proportion of activated carbon particles, and that the surface of the screw body is coated with activated carbon particles.
Für den Schneckenkörper kann anstel le der erwähnten orga¬ nischen Masse auch ein geeigneter keramischer Werkstoff ver¬ wendet werden. Schl ießl ich ist es aber auch mögl ich, als Schneckenkörper ein spiralförmig verdri l ltes Chen i I ledraht- element zu verwenden, dessen radial von der Drahtseele nach außen ragende Fadenstücke mit einer größtmögl ichen Menge an Aktivkohlepartikeln besetzt sind.Instead of the mentioned organic mass, a suitable ceramic material can also be used for the screw body. Finally, it is also possible to use a spirally twisted Chen I I wire element as the screw body, the thread pieces of which protrude radially outwards from the wire core are covered with the greatest possible amount of activated carbon particles.
Die vorgeschlagene Form eines Schneckenkörpers ermögl icht es, den Fi lter den vorgegebenen Bedingungen in idealer Weise anzupassen, da sich die Anzahl der Flächen wie auch deren Steigung bzw. ihr Neigungswinkel in solcher Weise festlegen lassen, daß die gewünschte Wirksamkeit zuver¬ lässig sichergestel lt ist. Um die Sc-hneckenkörper der in Betracht kommenden Art an ihren Oberflächen bestmögl ich mit Aktivkohlepartikeln beschichten zu können, wird zur Haftvermittlung ein geeignetes Bindemittel , beispielsweise ein Cel lulose- Klebstoff oder Pol yv i ny I al kohol od.dgl . verwendet, welches die Adsorpt ionsei geπschaft der Aktivkohle¬ partikel n.icht beeinträchtigt.The proposed shape of a screw body makes it possible to adapt the filter to the given conditions in an ideal manner, since the number of surfaces as well as their incline or their angle of inclination can be determined in such a way that the desired effectiveness is reliably ensured . In order to be able to coat the screw bodies of the type in question as best as possible with activated carbon particles, a suitable binding agent, for example a cellulose adhesive or polyvinyl alcohol or the like, is used to promote adhesion. used, which does not adversely affect the adsorption of the activated carbon particles.
Weitere Merkmale und konstruktive Einzelheiten der erfin¬ dungsgemäß ausgebi ldeten Fi lter gehen aus den Unteran¬ sprüchen und der nachfolgenden Beschreibung der in den Figuren 1 bis 5 der Zeichnung dargestel lten bevorzugten Ausführungsbeispiele hervor. Es zeigen:Further features and constructive details of the filters designed according to the invention are evident from the subclaims and the following description of the preferred exemplary embodiments shown in FIGS. 1 to 5 of the drawing.

Fig. 5 einen Axialschnitt durch eine Fi lterpatrone mit einem Schneckenkörper nach Fig. 1 als Kern, welcher von einer Papier- bzw. Karton¬ hülse umgeben ist. Der in Fig. 1 dargestel lte Fi lterkern besteht aus .einem mehrgängigen, vorl iegend dreigängigen Schneckenkörper 11, der, wie aus Fig. 2 ersichtl ich, aus- drei im Querschnitt sternförmig angeordneten, die Gänge der Schnecke bi ldenden Bändern 12 besteht, die längs der Achse 13 miteinander ver¬ bunden sind und über die Länge des Schneckenkörpers 11 um die Achse 13 spiralförmig gedreht sind.5 shows an axial section through a filter cartridge with a screw body according to FIG. 1 as the core, which is surrounded by a paper or cardboard sleeve. The filter core shown in FIG. 1 consists of a multi-start, predominantly three-start screw body 11, which, as can be seen from FIG. 2, consists of three star-shaped belts 12 which form the cross-sections of the screw and which form the threads of the screw are connected to one another along the axis 13 and are spirally rotated about the axis 13 over the length of the screw body 11.
Wie die Figuren 3a und 3b erkennen lassen, kann der Schneckenkörper 11 beispielsweise vier oder auch sechs Bänder 12 aufweisen. Selbstverständl ich können auch mehr solcher Bänder 12 vorgesehen werden.As can be seen in FIGS. 3a and 3b, the screw body 11 can have, for example, four or even six bands 12. Of course, more such tapes 12 can also be provided.
Der Schneckenkörper 11 besteht vorzugsweise aus einem porösen Werkstoff aus Stärke in Form von Mehl oder Hart- gries, welche einen entsprechenden Antei l an eiwei߬ haltigem Kleber besitzen. Reicht dieser Kleber noch nicht aus, um eine ausreichende Bindung der Stärkepartikel her¬ beizuführen, so kann der Masse zusätzl ich ein organisches Bindemittel, vorzugsweise Eiweiß, zugesetzt werden. Dieser Masse sind vorzugsweise ein Porenbi ldner sowie Aktivkohle¬ partikel zugesetzt, damit einerseits die Porosität des Schneckenkörpers eine gewünschte Größe annimmt und anderer seits die Adsorptionsfähigkeit gesteigert wird.The screw body 11 preferably consists of a porous material made of starch in the form of flour or semolina, which has a corresponding proportion of protein-containing adhesive. If this adhesive is not sufficient to ensure sufficient binding of the starch particles, an additional organic binder, preferably protein, can be added to the mass. A pore former and activated carbon particles are preferably added to this mass, so that on the one hand the porosity of the screw body assumes a desired size and on the other hand the adsorption capacity is increased.
Die Masse wird zweckmäßigerweise mittels eines Extruders zu einem schneckenförmigen Strang gepreßt, von welchem dann die Tei lstücke in gewünschter Länge abgetrennt werden. Die einzelnen Schneckenkörper werden an ihrer Oberfläche mit Aktivkohlepartikeln beschichtet, wodurch eine außerordentl ich gute Fi lterwirkung erreicht wird.The mass is expediently pressed by means of an extruder into a helical strand, from which the parts are then separated in the desired length. The surface of the individual snail bodies is coated with activated carbon particles, which results in an extraordinarily good filtering effect.
Um die Aktivkohlepartikel auf den in Betracht kommenden Oberflächen festhaftend zu befestigen, findet ein Binde- mittel Anwendung, welches gewährleistet, daß die Adsorp- t ionsfähi gei t der Aktivkohlepartikel wei testgehend er- hal ten bleibt.In order to fix the activated carbon particles firmly on the surfaces in question, a binding agent medium application, which ensures that the adsorption capacity of the activated carbon particles is maintained as far as possible.
Der in Fig. 4 dargestel lte, erfindungsgemäß ausgebi ldete Schneckenkörper kann aber auch aus einem spiralförmigen Cheni I I edrahtel ement 14 bestehen. Die zwischen zwei ver¬ dri l lten Drähten der Seele 15 eingespannten Fadenstücke 16, welche längs der Seele 15 spiralförmig angeordnet sind, sind so dicht wie mögl ich mit Aktivkohlepartikeln besetzt, wobei zum Zwecke des Anhaftens an den Fadenstücken gleichfal ls ein geeignetes Bindemittel Anwendung findet.The screw body shown in FIG. 4 and embodied according to the invention can also consist of a spiral Cheni I wire element 14. The pieces of thread 16 clamped between two twisted wires of the core 15, which are arranged spirally along the core 15, are filled with activated carbon particles as densely as possible, a suitable binder also being used for the purpose of adhering to the thread parts .
Da die zuvor beschriebenen Schneckenkörper 11 bei indu¬ striel ler Produktion relativ große Toleranzen hinsicht¬ l ich vorgegebener Dimensionswerte aufweisen, und auch mehr oder weniger empfindl ich sind, und weiterhin der Dichtheit zwischen dem Filter und der diesen umgebenden Wand des Hohlraums, in welchen der Fi lter eingesetzt ist, eine bedeutende Rol le zukommt, werden die Schnecken¬ körper 11 mit einer Papier- oder Kartonhülse 17 umhül lt, um so eine Fi lterpatrone 21 zu bi lden, welche in den dafür vorgesehenen Hohlraum in einer Tabakpfeife oder einer Zigaretten- oder Zi garrenspi tze ei nzustecken ist, wöbe i sie mögl ichst dicht an die Wandung des Hohlraums ari¬ sch I i eßen sol I .Since the previously described screw bodies 11 have relatively large tolerances with regard to predetermined dimension values in industrial production and are also more or less sensitive, and furthermore the tightness between the filter and the wall of the cavity surrounding it, in which the If a filter is used, an important role is played, the screw bodies 11 are wrapped in a paper or cardboard sleeve 17 in order to form a filter cartridge 21 which is inserted into the cavity provided in a tobacco pipe or a cigarette or cigarspitze is to be plugged in, I want it to be as close as possible to the wall of the cavity.
Besonders vortei lhaft ist es daher, den den Kern des Fi lters bi ldenden Schneckenkörper 11 mit einer verhältnismäßig lockeren Faserv I ies I age 19 zu umgeben und diesen dann in die Papier- bzw. Kartonhülse 17' hineinzustecken, die zu diesem Zweck an einem Ende eine Aufweitung 20 aufweist. Letztere hat überdies die Aufgabe, daß die solchermaßen ausgebi ldete Fi I terpat rone 21 mit ihrer Papier- bzw. Karton¬ hülse 17' an der Wandung der Bohrung von Tabakpfeifen bzw. Zigaretten- oder Zigarrenspitzen, in die der Fi lter einge¬ setzt ist, abdichtend anl iegt, um zu vermeiden, daß Tabak¬ rauch durch den Zwischenraum zwischen dem Fi lter und der Bohrungswandung indurchströmt, was dort zu unerwünschter Kondensatbi ldung führt. Die Faserv I i es I age 19 an der Innen¬ seite der Hülse 17' dichtet die Schneckengänge 12 gegen diese ab, damit der Tabakrauch gezwungen wird, den Schnecken¬ körper 11 spiralförmig zu durchströmen. Es ist aber auch mögl ich, die unerwünschte Kondensatbi ldung dadurch zu be¬ heben, daß man auf der Außenseite der Papier- bzw. Karton¬ hülse 17 elastische Partikel , wie z.B. Flocken, Fasern od.dgl . Material in geeigneter Schichtstärke anbringt, um die gewünschte Abdichtung zu erzielen.It is therefore particularly advantageous to surround the snail body 11 forming the core of the filter with a relatively loose fiber fleece 19 and then insert it into the paper or cardboard sleeve 17 ', which for this purpose has one end has an expansion 20. The latter also has the task that the so trained filter cartridge 21 rests with its paper or cardboard sleeve 17 'on the wall of the bore of tobacco pipes or cigarette or cigar tips into which the filter is inserted, in order to avoid that tobacco smoke flows through the space between the filter and the bore wall, which leads to undesirable condensate formation there. The fiber structure 19 on the inside of the sleeve 17 'seals the screw flights 12 against it, so that the tobacco smoke is forced to flow through the screw body 11 in a spiral. However, it is also possible to remove the undesirable condensate formation by placing 17 elastic particles, such as flakes, fibers or the like, on the outside of the paper or cardboard sleeve. Apply material in a suitable layer thickness to achieve the desired seal.
Zweckmäßigerweise ist die Papier- bzw. Kartonhülse 17 an ihrer Innenseite gleichfal ls mit adsorbierenden Aktiv¬ kohl epartkel n beschichtet, wodurch di e Wi rksamkei t des Fi lters noch verbessert wird. Anstel le der Aktivkohle¬ partikel können aber auch geeignete Fasermaterial ien Ver¬ wendung finden, die dann zusätzl ich mit Aktivkohleparti eln versetzt sein können.The paper or cardboard sleeve 17 is expediently also coated on the inside with adsorbing activated carbon particles, as a result of which the effectiveness of the filter is further improved. Instead of the activated carbon particles, however, suitable fiber material can also be used, which can then also be mixed with activated carbon particles.
Um eine einfache und saubere Entnahme einer verbrauchten, erfindungsgemäß ausgebi ldeten Fi I terpat rone aus einer Tabakpfeife oder einer Zigarren- oder Zigarettenspitze zu ermögl ichen, ist an dieser vortei lhafterweise ein Faden¬ oder Drahtstück 18 befestigt, an dem man anfassen kann, um die Fi I erpat rone aus dem sie aufnehmenden Hohlraum her- auszuz i ehen.In order to enable a simple and clean removal of a used filter cartridge, designed in accordance with the invention, from a tobacco pipe or a cigar or cigarette holder, a thread or wire piece 18 is advantageously attached to this, on which one can grip around the Pull the cartridge out of the cavity that receives it.
Die erfindungsgemäß ausgebi ldeten Fi lterpatronen lassen sich rationel l und insbesondere kostengünstig herstel len. Sie weisen eine hohe Adsorptionsfähigkeit für die aus den Rauchgasen zu entfernenden Substanzen auf, welche be¬ trächtl ich über derjenigen bisher verwendeter Fi lter I iegt .The filter cartridges designed in accordance with the invention can be produced economically and in particular cost-effectively. They have a high adsorption capacity for the substances to be removed from the flue gases, which is considerably higher than that of previously used filters.
