Es ist eine Aufgabe der Erfindung, eine Filtervorrichtung für Zigaretten und/oder Pfeifen bereitzustellen, welche verbesserte Filtereigenschaften aufweist.It is an object of the invention to provide a filter device for cigarettes and/or pipes which has improved filter properties.

Diese Aufgabe wird durch die Merkmale der Ansprüche 1 und 5 gelöst.This object is solved by the features of claims 1 and 5.

In bisher noch nicht veröffentlichten Voruntersuchungen konnte von den Erfindern überraschenderweise festgestellt werden, dass Filtervorrichtungen zumindest einer mit einer Salzschicht beschichtete Filterschichte im Vergleich zu herkömmlichen Filtervorrichtungen eine deutlich verbesserte Filterwirkung aufweisen. Mit Hilfe der Röntgen-Fluoreszenz-Analyse konnte eine erhöhte Sorptionsfähigkeit der Filtervorrichtung bei den Elementen Blei, Strontium, Calcium und Vanadium nachgewiesen werden.In previously unpublished preliminary studies, the inventors surprisingly found that filter devices at least one with a Salt layer coated filter layer compared to conventional filter devices have a significantly improved filter effect. With the help of X-ray fluorescence analysis, an increased sorption capacity of the filter device for the elements lead, strontium, calcium and vanadium could be demonstrated.

Es kann vorgesehen sein, dass die Filtervorrichtung zwei oder mehrere Filterschichten umfasst.It can be provided that the filter device comprises two or more filter layers.

Es kann vorgesehen sein, dass die zwei oder mehreren Filterschichten zumindest abschnittsweise miteinander verbunden sind. Beispielsweise können die Filterschichten miteinander verklebt sein, um solcherart ein gegenseitiges Verschieben der einzelnen Filterschichten zu vermeiden.Provision can be made for the two or more filter layers to be connected to one another at least in sections. For example, the filter layers can be glued together in order to prevent the individual filter layers from shifting relative to one another.

Es kann vorgesehen sein, dass die zumindest eine Filterschicht in Form einer einschichtig gepressten Tablette ausgebildet ist, vorzugsweise mit einer Dicke von 0,1 bis 100 µm.Provision can be made for the at least one filter layer to be in the form of a single-layer pressed tablet, preferably with a thickness of 0.1 to 100 μm.

Besonders zweckmäßig kann es sein, wenn bei einer erfindungsgemäßen Filtervorrichtung zwei oder mehrere Filterschichten aus unterschiedlichen Trägermedien hergestellt sind.It can be particularly expedient if, in a filter device according to the invention, two or more filter layers are produced from different carrier media.

Als Trägermaterialien, die die mit Salz beschichteten Filterschichten bilden, können beispielsweise Textilmaterialien aus Leinen oder Baumwolle, Mull, und/oder Vliesstoff eingesetzt werden.Textile materials made of linen or cotton, gauze and/or non-woven fabric can be used, for example, as carrier materials which form the filter layers coated with salt.

Besonders vorteilhaft kann es sein, wenn das anorganische Salz, welches die Salzschicht bildet, ein Natriumsalz enthält. Zweckmäßig wird zur Beschichtung beispielsweise eine Kochsalzlösung verwendet. Die Salzschicht gemäß der Erfindung kann somit auch nur aus einem einzigen anorganischen Salz, vorzugsweise einem Natriumsalz, besonders bevorzugt aus Kochsalz, bestehen.It can be particularly advantageous if the inorganic salt which forms the salt layer contains a sodium salt. A saline solution, for example, is expediently used for the coating. The salt layer according to the invention can therefore also consist of only a single inorganic salt, preferably a sodium salt, particularly preferably common salt.

Es kann vorgesehen sein, dass die Salzschicht zumindest ein weiteres Salz umfasst, das ausgewählt ist aus der Gruppe bestehend aus: Kaliumsalz, Calciumsalz, Magnesiumsalz, Mangansalz. Im Rahmen der Erfindung können neben Kochsalz auch noch andere Salze oder Salzmischungen eingesetzt werden. Beispielsweise kann auch Meersalz zum Beschichten der Salzschichten auf den Trägermedien verwendet werden. Die Salzblume von Meersalz besteht beispielhaft im Mittel aus über 97 % Natriumchlorid, 0,5 % Calciumsulfat, 0,3 % Magnesiumchlorid, 0,2 % Magnesiumsulfat ("Bittersalz") und etwa 0,1 % Kaliumchlorid, der Rest ist verbliebenes Wasser.Provision can be made for the salt layer to comprise at least one further salt which is selected from the group consisting of: potassium salt, calcium salt, magnesium salt, manganese salt. In addition to table salt, other salts or salt mixtures can also be used within the scope of the invention. For example, sea salt can also be used to coat the salt layers on the support media. The salt flower of Sea salt, for example, consists on average of more than 97% sodium chloride, 0.5% calcium sulfate, 0.3% magnesium chloride, 0.2% magnesium sulfate ("Epsom salt") and about 0.1% potassium chloride, the rest is remaining water.

Es kann vorgesehen sein, dass die Salzschicht eine Schichtdicke von 0,5 bis 10 µm, vorzugsweise 1 bis 5 µm, aufweist.It can be provided that the salt layer has a layer thickness of 0.5 to 10 μm, preferably 1 to 5 μm.

Die Aufgabe wird ebenso gemäß Anspruch 5 dadurch gelöst, dass die Filtervorrichtung zumindest eine Salzsolekapsel umfasst, wobei die zumindest eine Salzsolekapsel eine wässrige Salzlösung enthält, die von einer Kapselhülle umgeben ist, wobei die zumindest eine Salzsolekapsel an der zumindest einen Filterschicht angeordnet ist.The object is also achieved according to claim 5 in that the filter device comprises at least one brine capsule, the at least one brine capsule containing an aqueous salt solution which is surrounded by a capsule shell, the at least one brine capsule being arranged on the at least one filter layer.

In den Voruntersuchungen der Erfinder hat sich überraschend gezeigt, dass durch Befeuchten der Salzschichten auf der zumindest eine Filterschicht die Filterwirkung der Filtervorrichtung weiter verbessert werden kann. Eine oder mehrere Salzsolekapseln, die in der Filtervorrichtung integriert sind und die durch einfaches Zusammendrücken geöffnet werden können, um sodann die darin befindliche Salzsole freizusetzen, sind eine besondere komfortable Variante, um die erfindungsgemäße Filtervorrichtung vor oder während des Rauchens befeuchten zu können.The preliminary investigations of the inventors surprisingly showed that the filter effect of the filter device can be further improved by moistening the salt layers on the at least one filter layer. One or more brine capsules, which are integrated in the filter device and which can be opened by simply squeezing to then release the brine contained therein, are a particularly convenient variant for moistening the filter device according to the invention before or during smoking.

Unter dem Begriff "Salzsole" versteht man eine wässrige Lösung von Salzen, die mindestens 14 g gelöster Stoffe pro 1 kg Wasser enthält. Die Bezeichnung Salzsole wird heute hauptsächlich für entsprechend konzentrierte Natriumchlorid-Lösungen verwendet.The term "brine" means an aqueous solution of salts containing at least 14 g of dissolved substances per 1 kg of water. The term brine is mainly used today for appropriately concentrated sodium chloride solutions.

Es kann vorgesehen sein, dass die Salzlösung eine Kochsalzlösung mit einer Salzkonzentration von 0,9 bis 35,9% ist.It can be provided that the saline solution is a saline solution with a salt concentration of 0.9 to 35.9%.

Beispielsweise können eine isotonische Kochsalzlösung, oder eine zum Blutplasma isoosmotische Lösung aus Kochsalz (Natriumchlorid) in injektionsgeeignetem Wasser zur Beschichtung des Trägermediums verwendet werden.For example, an isotonic saline solution or a solution of saline (sodium chloride) in injection-suitable water that is isoosmotic to the blood plasma can be used for coating the carrier medium.

Es kann vorgesehen sein, dass die zumindest eine Salzsolekapsel von 0,1 bis 1 ml einer wässrigen Salzlösung enthält.Provision can be made for the at least one brine capsule to contain from 0.1 to 1 ml of an aqueous saline solution.

Es kann vorgesehen sein, dass die Kapselhülle der zumindest einen Salzsolekapsel durch äußere Krafteinwirkung öffenbar ist, wobei die Kapselhülle vorzugsweise aus Gelatine oder einem Gelatine-enthaltenden Material hergestellt ist.It can be provided that the capsule shell of the at least one brine capsule can be opened by external force, the capsule shell preferably being made of gelatine or a material containing gelatine.

Es kann vorgesehen sein, dass das Trägermedium aus Mull, Leinen und/oder Vliesstoff gebildet ist.Provision can be made for the carrier medium to be formed from gauze, linen and/or non-woven fabric.

Die Aufgabe wird ebenso gelöst durch eine Zigarette mit zumindest einer erfindungsgemäßen Filtervorrichtung.The object is also achieved by a cigarette with at least one filter device according to the invention.

Die Aufgabe wird ebenso gelöst durch eine Pfeife mit zumindest einer erfindungsgemäßen Filtervorrichtung.The object is also achieved by a whistle with at least one filter device according to the invention.
