Description

Die Erfindung betrifft eine Filtervorrichtung für eine Zigarette und/oder Pfeife zur Filterung von gesundheitsschädlichen Stoffen beim Rauchen, wobei die Filtervorrichtung zumindest eine Filterschicht mit einem Trägermedium umfasst.The invention relates to a filter device for a cigarette and / or pipe for filtering harmful substances when smoking, the filter device comprising at least one filter layer with a carrier medium.

Weiters betrifft die Erfindung eine Zigarette mit zumindest einer erfindungsgemäßen Filtervorrichtung.The invention further relates to a cigarette with at least one filter device according to the invention.

Weiters betrifft die Erfindung eine Pfeife mit zumindest einer erfindungsgemäßen Filtervorrichtung.The invention further relates to a whistle with at least one filter device according to the invention.

Rauchen ist die Hauptursache für die Entwicklung vieler letaler Krankheiten. Derartige Folgen des Rauchens führen nicht nur zu einer Verschlechterung des Allgemeinbefindens und der Arbeitsfähigkeit, sondern fügen allen Organen und Systemen im menschlichen Organismus Schaden zu.Smoking is the leading cause of the development of many lethal diseases. Such consequences of smoking not only lead to a deterioration in general well-being and the ability to work, but also damage all organs and systems in the human organism.

Der Zigarettenrauch, der vom Menschen beim Rauchen eingeatmet wird enthält Schwefel, Chlor, Kalium, Calcium, Brom und praktisch das gesamte Spektrum von Schwermetallen wie Blei, Cadmium, Chrom, Mangan, Eisen, Kupfer, Strontium, Zink und Nickel.The cigarette smoke inhaled by humans when smoking contains sulfur, chlorine, potassium, calcium, bromine and practically the entire spectrum of heavy metals such as lead, cadmium, chromium, manganese, iron, copper, strontium, zinc and nickel.

Im Zigarettenrauch sind mehr als die Hälfte der Gesamtmenge aller chemischen Komponenten enthalten, welche in der Zigarette selbst enthalten sind, wobei die Gesamtmenge an Schwermetallen im Rauch sowohl klassischer als auch leichter Zigaretten die gleiche ist.Cigarette smoke contains more than half of the total amount of all chemical components that are contained in the cigarette itself, the total amount of heavy metals in the smoke of both classic and light cigarettes being the same.

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 dadurch gelöst, dass die zumindest eine Filterschicht eine Salzschicht aufweist, welche auf dem Trägermedium angeordnet ist, wobei die Salzschicht aus zumindest einem anorganischen Salz gebildet ist.This object is achieved in that the at least one filter layer has a salt layer which is arranged on the carrier medium, the salt layer being formed from at least one inorganic salt.

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 preliminary studies that have not yet been published, the inventors surprisingly found that filter devices at least one with a Filter layers coated with a salt layer have a significantly improved filter effect compared to conventional filter devices. With the help of the X-ray fluorescence analysis, it was possible to detect an increased sorption capacity of the filter device for the elements lead, strontium, calcium and vanadium.

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.It can be provided that the two or more filter layers are connected to one another at least in sections. For example, the filter layers can be glued to one another in order to avoid mutual displacement of the individual filter layers.

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.It can be provided that the at least one filter layer is designed 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 useful if, in a filter device according to the invention, two or more filter layers are made 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 nonwoven, for example, can be used 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. For example, a saline solution is expediently used for the coating. The salt layer according to the invention can thus only consist of 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.It can be provided that the salt layer comprises at least one further salt 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 carrier media. The salt flower of Sea salt, for example, consists on average of over 97% sodium chloride, 0.5% calcium sulphate, 0.3% magnesium chloride, 0.2% magnesium sulphate ("Epsom salt") and about 0.1% potassium chloride, the remainder being 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 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 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 inventors' preliminary investigations have surprisingly shown 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 them together in order to then release the brine contained therein, are a particularly convenient variant to be able to moisten 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 which contains at least 14 g of dissolved substances per 1 kg of water. Today, the term brine is mainly used 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) iso-osmotic to the blood plasma in injection-suitable water can be used to coat the carrier medium.

Es kann vorgesehen sein, dass die zumindest eine Salzsolekapsel von 0,1 bis 1 ml einer wässrigen Salzlösung enthält.It can be provided that the at least one salt brine capsule contains from 0.1 to 1 ml of an aqueous salt 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 salt brine capsule can be opened by the action of external force, the capsule shell preferably being made of gelatin or a material containing gelatin.

Es kann vorgesehen sein, dass das Trägermedium aus Mull, Leinen und/oder Vliesstoff gebildet ist.It can be provided that the carrier medium is formed from gauze, linen and / or nonwoven 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.
