Abstract
Description
Die Neuerung betrifft zur einmaligen Verwendung vorgesehene Aufsteckfilter für Zigaretten.The innovation concerns clip-on filters for cigarettes intended for single use.
Zigarettenspitzen mit Filterpatronen, die beispielsweise mit Aktivkohle gefüllt sind, die beim Rauchen der Zigaretten im Tabakrauch enthaltene gesundheitsschädliche sowie die den Raucher beim Rauchen störende Stoffe zurückhalten sollen, sind im Handel.Cigarette holders with filter cartridges, which are filled with activated carbon, for example, are said to contain harmful substances contained in tobacco smoke when smoking cigarettes, and substances that are harmful to smokers when smoking are on the market.
Die bekannten Zigarettenspitzen sind zur mehrfachen Benutzung vorgesehen; die Wirkung ihrer Filterelemente ist nicht immer befriedigend.The known cigarette tips are intended for multiple use; the effect of their filter elements is not always satisfactory.
Der Neuerung liegt, die Aufgabe zugrunde, zur einmaligen Verwendung vorgesehene Filter zum Aufstecken auf Zigaretten vorzuschlagen, deren Länge der Länge üblicher Zigaretten integraler Mundstücke entspricht, die bei bestimmungsgemäßer Verwendung infolge des besonderen Filtereinsatzes hoch wirksam sind.The innovation is based on the task of proposing filters for single use to be placed on cigarettes, the length of which corresponds to the length of conventional cigarettes with integral mouthpieces, which are highly effective when used as intended due to the special filter insert.
Die der Neuerung zugrunde liegende Aufgabe wird gelöst durch ein Aufsteckfilter der in Anspruch 1 angegebenen Ausbildung.The object on which the innovation is based is achieved by a plug-on filter of the design specified in
Vorteilhafte Ausgestaltungen des neuerungsgemäßen Aufsteckfilters sind in den Unteransprüchen angegeben.Advantageous refinements of the plug-on filter according to the innovation are specified in the subclaims.
Das Aufsteckfilter besteht aus einem Rohrkörper und einer im Rohrkörperhohlraum angeordneten Filterscheibe.The clip-on filter consists of a tubular body and a filter disk arranged in the tubular body cavity.
Der Rohrkörper besteht bevorzugt aus Kunststoffolie, insbesondere bevorzugt transparenter Kunststoffolie.The tubular body preferably consists of plastic film, particularly preferably transparent plastic film.
Die Länge des Hohlkörpers entspricht vorteilhaft der Länge zigarettenintegraler Mundstücke handelsüblicher Zigaretten.The length of the hollow body advantageously corresponds to the length of cigarette-integral mouthpieces of commercially available cigarettes.
Der Rohrkörperinnendurchmesser ist dem Außendurchmesser der Zigarette derart angepaßt, daß der Rohrkörper auf diese aufschiebbar ist, wobei der Rohrkörper teilweise der Umfangsfläche der Zigarette unter leichter Spannung anliegt.The inside diameter of the tube body is adapted to the outside diameter of the cigarette in such a way that the tube body can be pushed onto it, the tube body partially abutting the circumferential surface of the cigarette under slight tension.
In der Beschreibung und in den Ansprüchen wird als erstes Ende des Rohrkörpers dasjenige desselben bezeichnet, von dem aus bei bestimmungsgemäßer Verwendung des Filters die Zigarette in den Rohrkörperhohlraum eingeschoben wird.In the description and in the claims, the first end of the tubular body is the one from which the cigarette is inserted into the tubular body cavity when the filter is used as intended.
Das zweite Rohrkörperende liegt dem ersten gegenüber; es umfaßt ein rohrkörperintegrales Widerlager- und Stützelement, das die Mündungsöffnung des Rohrkörperhohlraums am zweiten Rohrkörperende unter Freilassung einer zentralen Öffnung teilweise verlegt.The second tubular body end is opposite the first; it comprises an abutment and support element which is integral with the tubular body and which partially displaces the mouth opening of the tubular body cavity at the second end of the tubular body, leaving a central opening free.
Der Rohrkörper kann im Bereich seines ersten Endes eine Zone umfassen, die derart konisch ausgebildet ist, daß sich der Durchmesser des Rohrkörpers im Bereich dieser bis zum ersten Rohrende stetig vergrößert.In the area of its first end, the tubular body can comprise a zone which is conical in such a way that the diameter of the tubular body is in the area thereof steadily enlarged up to the first pipe end.
Das rohrkörperintegrale Widerlager- und Halteelement am zweiten Rohrkörperende dient zur Lagefixierung der Filterscheibe im Rohrkörperhohlraum.The abutment and holding element integral to the tubular body at the second end of the tubular body serves to fix the position of the filter disk in the hollow space of the tubular body.
Definitionsgemäß soll die technische Bedeutung der Bezeichnung "Widerlager- und Halteelement" sowohl eine Stirnwand mit zentraler Kreisöffnung am zweiten Rohrkörperende umfassen, als auch einen in den Rohrkörperhohlraum gestülpt ausgebildeten kreisringförmigen Bördelrand.According to the definition, the technical meaning of the term “abutment and holding element” is intended to include both an end wall with a central circular opening at the second end of the tubular body and an annular flanged edge that is placed inside the hollow body cavity.
Das Widerlager-und Halteelement in seinen beiden angegebenen baulichen Varianten erfüllt gegenüber der Filterscheibe jeweils die gleiche Funktion, nämlich ihre Lage im Rohrkörperhohlraum derart festzulegen, daß sie beim Einschieben der Zigarette in den Rohrkörperhohlraum vom ersten Ende des Rohrkörpers her 'nicht aus diesem herausgedrückt wird.The abutment and holding element in its two specified structural variants fulfills the same function in relation to the filter disk, namely to determine its position in the tubular body cavity in such a way that when the cigarette is inserted into the tubular body cavity from the first end of the tubular body it is not pushed out of it.
Der Durchmesser des Rohrkörpers wird im Bereich der Rohrkörperstirnwand mit zentraler Öffnung bzw. dem kreisringförmigen Bördel jeweils partiell derart verringert, daß die Filterscheibe durch die bezeichneten Elemente lagefixiert wird.The diameter of the tubular body is partially reduced in the region of the tubular body end wall with a central opening or the annular flange in such a way that the filter disk is fixed in position by the elements described.
Der den Rohrhohlraumdurchmesser verringernde kreisringförmige Bördelrand entsteht dadurch, daß man am zweiten Rohrkörperende einen endkantennahen Bereich in warmformbaren Zustand überführt und ihn unter Einstülpung über seine gesamte Umfangslinie nach innen bördelt und dann abkühlt.The annular flanged edge which reduces the tube cavity diameter is created by converting an area near the end edge into a thermoformable state at the second end of the tube body and turning it over with an indentation flaps its entire circumference inwards and then cools down.
Die Filterscheibe ist schwammartig porös strukturiert aufgebaut und besteht aus regenerierter Cellulose (Cellulosehydrat).The filter disc has a porous, sponge-like structure and consists of regenerated cellulose (cellulose hydrate).
Die poröse, schwammartige Struktur der Filterscheibe macht diese für Zigarettenrauch durchlässig. Durch ihre große Oberfläche und infolge des sie bildenden Werkstoffs mit hoher Flüssigkeits-Rückhaltefähigkeit ist die Filterscheibe in hohem Maße befähigt, Zigarettenrauch enthaltende gesundheitsschädliche oder den Raucher störende Bestandteile des Zigarettenrauchs aufzunehmen und zurückzuhalten.The porous, sponge-like structure of the filter disc makes it permeable to cigarette smoke. Due to its large surface area and the material with a high liquid retention capacity that forms it, the filter disk is highly capable of absorbing and retaining components of the cigarette smoke that are harmful to health or disturb the smoker.
Der Durchmesser der im Rohrkörperhohlraum angeordneten Filterscheibe ist dem Innendurchmesser des Hohlkörpers derart angepaßt, daß die Innenseite des Rohrkörpers der Umfangsfläche der im Querschnitt kreisförmigen Filterscheibe unter leichter Preßkrafteinwirkung fest anliegt. Die Filterscheibe grenzt dabei mit einer Oberfläche vorteilhaft unmittelbar an das Widerlager und Halteelement des Rohrkörpers an.The diameter of the filter disk arranged in the tubular body cavity is adapted to the inside diameter of the hollow body in such a way that the inside of the tubular body bears firmly against the circumferential surface of the filter disk which is circular in cross section with the action of a slight compressive force. The filter disk advantageously adjoins with a surface directly on the abutment and holding element of the tubular body.
Die Filterscheibe hat eine Dicke, die vorteilhaft etwa einem Viertel der Länge des Hohlkörpers entspricht.The filter disk has a thickness which advantageously corresponds to approximately a quarter of the length of the hollow body.
Zur Herstellung des Filters geht man beispielsweise von einem einwandigen Rohr mit oder ohne Längsnaht aus, das aus Kunststoffolie.besteht, beispielsweise einem Rohr aus weichmacherfreiem Polyvinylchlorid, das beispielsweise eine Wandstärke von 100 /um besitzt.For the preparation of the filter it is, for example, of a single-walled tube with or without a longitudinal seam, the Kunststoffolie.besteht from, for example, a tube made of unplasticized polyvinyl chloride, for example, a wall thickness of 100 / um has.
Ein Endabschnitt des Kunststoffrohres wird dann durch Erwärmen auf eine Temperatur gebracht, bei der das Rohr warmformbar ist. Der erwärmte Endabschnitt des Rohres wird dann über die gesamte Länge des Umfangs nach innen derart um- und in den Rohrhohlraum eingestülpt, daß am derart behandelten Kunststoffrohrende ein kreisringförmiger umlaufender Folienbördel mit zentraler kreisförmiger öffnung entsteht.An end portion of the plastic tube is then heated to a temperature at which the tube is thermoformable. The heated end section of the tube is then turned over the entire length of the circumference and turned inside the tube cavity in such a way that an annular, circumferential film flange with a central circular opening is formed at the plastic tube end treated in this way.
Man läßt den wärmebeaufschlagten Rohrbereich bzw. den gebildeten Bördel dann abkühlen.The heat-affected tube area or the flare formed is then allowed to cool.
Danach wird eine kreisförmige Filterscheibe der genannten Ausbildung vom anderen Ende des Rohres her in dessen Hohlraum derart ein- und in diesem soweit in Richtung auf das zweite Rohrende zugeschoben, daß eine Oberfläche der Filterscheibe an den integralen Bördel angrenzt.Thereafter, a circular filter disk of the aforementioned design is inserted from the other end of the tube into its cavity and pushed so far in the direction of the second tube end that a surface of the filter disk adjoins the integral flange.
Das zur einmaligen Verwendung vorgesehene Aufsteckfilter für Zigaretten kann entweder bereits vom Zigarettenhersteller auf die Mundstückseite der Zigarette aufgeschoben werden oder erst vom Käufer der Zigarette.The clip-on filter for cigarettes intended for single use can either be pushed onto the mouthpiece side of the cigarette by the cigarette manufacturer or only by the buyer of the cigarette.
Die Zeichnung erläutert die Neuerung.The drawing explains the innovation.
In der Zeichnung ist schematisch und im Querschnitt das Aufsteckfilter für Zigaretten beispielhaft dargestellt.In the drawing, the clip-on filter for cigarettes is shown schematically and in cross-section as an example.
In der Zeichnung bedeutet 1 den Rohrkörper, 2 den Rohrkörperhohlraum, 3 das erste Rohrkörperende, 4 das zweite Rohrkörperende, 5 ein sich konisch erweiterndes Endteil des Rohrkörpers, 6 ist ein rohrkörperintegraler, kreisringförmiger Bördel am zweiten Rohrkörperende, der ein rohrkörperintegrales Widerlager- und Halteelement für die im Rohrkörperhohlraum 2 angeordnete Filterscheibe 7 bildet. 8 ist eine, in den Rohrkörperhohlraum eingeführte Zigarette.In the drawing, 1 means the tubular body, 2 the tubular body cavity, 3 the first tubular body end, 4 the second tubular body end, 5 a conically widening end part of the tubular body, 6 is a tubular body-integral, annular flange at the second tubular body end, which is an abutment and holding element integral to the tubular body the
