Description

Die vorliegende Erfindung betrifft einen Aufgußbeutel, vorzugsweise Doppelkammer-Aufgußbeutel, insbesondere zur Bereitung von Tee, mit mindestens einer aus einem Filtermaterial bestehenden, ein Substanzquantum enthaltenden Kammer, die an ihrem Kopfende verschlossen ist, an dem ein Faden mit einem als Handhabe und/oder zur Information dienenden Etikett befestigt ist.The present invention relates to an infusion bag, preferably a double-chamber infusion bag, especially for making tea, with at least one consisting of a filter material containing a substance quantum Chamber, which is closed at the head end, on which a thread with an as Handle and / or informational label is attached.

Aufgußbeutel für Tee sind in verschiedenen Ausführungsformen gebräuchlich. Insbesondere hat sich die Verwendung von Doppelkammer-Aufgußbeuteln durchgesetzt, die zwei benachbart zueinander angeordnete, Seite an Seite liegende Kammern aufweisen, die jeweils ein Quantum von Teegut in Form von getrockneten und zerkleinerten Teeblättem enthalten. Die beiden Kammern sind am Boden durch eine Querfaltung, auch Bodenfalz genannt, miteinander verbunden und an ihrem Kopfende gemeinsam durch eine Verbindung verschlossen, an der ein Faden mit einem Etikett befestigt ist. In der Regel wird dazu ein in zwei Arbeitsgängen hergestellter Kopfverschlußfalz gebildet, indem in einem ersten Arbeitsgang die Ecken des Aufgußbeutels eingefaltet werden und in einem zweiten Arbeitsgang der an der Spitze stehenbleibende trapezförmige Teil umgelegt wird. Daraufhin werden die eingefalteten Teile durch eine Verbindung unter gleichzeitiger Befestigung eines Fadenendes aneinandergeheftet. Ein derartiger Doppelkammer-Aufgußbeutel ist beispielsweise aus der GB-A-1 157 513 bekannt. Er besteht aus einem leicht durchlässigen Material, welches es der Aufgußflüssigkeit ermöglicht, die auszulaugende Substanz, insbesondere den Tee, aufzuschließen und die darin enthaltenen Stoffe zu lösen. Tea infusion bags are used in various forms. In particular, the use of double-chamber infusion bags enforced, the two adjacent to each other, side by side Have chambers, each a quantity of tea in the form of contains dried and crushed tea leaves. The two chambers are on the floor with a cross fold, also called floor fold, with each other connected and closed together at the head end by a connection, to which a thread is attached with a label. Usually this becomes a two-step head lock fold is formed by in one first operation, the corners of the infusion bag are folded and in one second step the trapezoidal part that remains at the top is thrown. Then the folded parts are connected tacked together while fastening one end of the thread. On such a double chamber infusion bag is for example from the GB-A-1 157 513 known. It's made of a slightly permeable material, which enables the infusion liquid to extract the substance to be leached out, especially the tea, to digest and dissolve the substances contained therein.

Hierzu finden insbesondere Filterpapiermaterialien Verwendung. Zur Befestigung des Fadens am Aufgußbeutel bzw. am Etikett und zur Verbindung des Kopfverschlußfalzes ist es bekannt, Verschlußklemmen aus Metall - sogenannte Heftel - zu verwenden, die im Bereich des Falzes des Kopfendes des Aufgußbeutels bzw. am Etikett angeordnet werden.In particular filter paper materials are used for this. For fixing of the thread on the infusion bag or on the label and for connecting the Head closure fold it is known, closure clamps made of metal - so-called Booklet - to be used in the area of the fold of the head end of the Aufgußbeutels or be arranged on the label.

Ferner ist es beispielsweise aus der DE-U-296 13 448 bekannt, den Faden zur Befestigung am Aufgußbeutel bzw. an dem Etikett mit diesem zu vernähen.Furthermore, it is known for example from DE-U-296 13 448 to thread the Attach the attachment to the infusion bag or the label with it.

Eine sichere Verbindung bzw. Befestigung des Aufgußbeutels mit dem Faden bzw. dem Etikett ist bei den bekannten Verbindungs- und/oder Befestigungsmöglichkeiten nicht immer gewährleistet. So ist insbesondere bei der Verwendung einer Verschlußklammer ein sicheres Einklemmen des Fadens nicht gewährleistet, so daß der Faden relativ einfach aus der Klammer herausrutschen und sich somit vom Etikett bzw. vom Aufgußbeutel lösen kann. Ein weiteres wesentliches Problem ist dadurch gegeben, daß die Verbindungsmedien, das heißt die Verschlußklemmen eine geschmacksverändemde bzw. -beeinflussende Wirkung haben und für den Verbraucher störend wirken.A secure connection or attachment of the infusion bag to the thread or the label is in the known connection and / or fastening options not always guaranteed. So is especially when using a closing clip does not ensure that the thread is clamped securely, so that the thread slides out of the clip relatively easily and thus can detach from the label or the infusion bag. Another essential The problem is that the connection media, that is Closure clamps have a taste-changing or influencing effect have and disrupt the consumer.

Das Vernähen des Fadens mit dem Aufgußbeutel bzw. mit dem Etikett vermeidet zwar eine geschmacksverändemde bzw. -beeinflussende Wirkung, weist aber herstellungstechnische Mängel auf. So muß beispielsweise der zum Vernähen vorgesehene Faden nach dem Vernähen eines ersten Aufgußbeutels und seines Etiketts zum Vernähen eines weiteren Aufgußbeutels um eine gewisse erforderliche Länge gezogen werden. Dabei kann es zu unerwünschten Verknotungen oder Verkettungen kommen, die sich allenfalls durch aufwendige Fadenführungsmaßnahmen vermeiden lassen.Avoid sewing the thread to the infusion bag or label a taste-changing or influencing effect, but has manufacturing defects. For example, it has to be sewn provided thread after sewing a first infusion bag and his Labels for sewing another infusion bag around a certain one required length. Doing so can cause unwanted effects Knots or concatenations occur, which are at most complicated Have thread guiding measures avoided.

Der Erfindung lag die Aufgabe zugrunde, einen gattungsgemäßen Aufgußbeutel, vorzugsweise Doppelkammer-Aufgußbeutel, so zu verbessern, daß ein zuverlässiger und hinsichtlich geschmacksverändernder bzw. -beeinflussender Wirkungen neutraler Kopferschluß des Aufgußbeutels mit integrierter Fadenhalterung geschaffen wird. The invention was based on the object, a generic Tea bags, preferably double-chamber tea bags, to improve so that a reliable one that changes or influences taste Effects of neutral head closure of the infusion bag with integrated Thread holder is created.

Die Aufgabe wird durch die Erfindung dadurch gelöst, daß das Kopfende der Kammer mittels eines Blattes aus heißsiegelfähigem Filterpapier verschlossen ist, das zugleich den Faden am Kopfende des Aufgußbeutels befestigt.The object is achieved by the invention in that the head end of the Chamber is closed by means of a sheet of heat-sealable filter paper, which also attaches the thread to the head of the infusion bag.

Unter Heißsiegeln wird ganz allgemein das Verbinden von zwei Stoffen bei erhöhter Temperatur verstanden. Die zu verbindenden Flächen werden dabei auf die Erweichungstemperatur des Materials erhitzt und durch Druck miteinander verbunden, wobei die Materialien bei der angewendeten Temperatur nicht plastisch werden. Die Erhitzung des Materials kann auf unterschiedliche Art und Weise erfolgen, beispielsweise mittels beheizter Metallplatten, durch Wärmeimpulse oder mittels Hochfrequenz. Durch das Heißsiegeln erhält man besonders feste Verbindungen, die die gleichen Eigenschaften aufweisen, wie die zum Heißsiegeln verwendeten Materialien.In general, heat sealing involves joining two substances together Temperature understood. The areas to be connected are assigned to the Softening temperature of the material heated and by pressure with each other connected, the materials not at the applied temperature become plastic. The heating of the material can be done in different ways and Way, for example by means of heated metal plates Heat impulses or by means of high frequency. By heat sealing you get particularly strong connections that have the same properties as the materials used for heat sealing.

Die Verwendung eines Blattes aus heißsiegelfähigem Filterpapier als Kopfverschluß des Aufgußbeutels hat den wesentlichen Vorteil, daß keine geschmacksverändemden bzw. -beeinflussenden Medien und/oder Materialien in mittelbarem bzw. unmittelbarem Kontakt mit dem in der Kammer enthaltenen Substanzquantum treten und gegebenenfalls störend wirken können, da heißsiegelfähiges Filterpapier keine geschmacksverändernden Stoffanteile aufweist. Ferner lassen sich so aufwendige Arbeitsgänge zum Verschließen der Aufgußbeutel vermeiden. Durch die flächige Verteilung und der Verbindung mit dem Filterpapier ist femer gewährleistet, daß die Verbindung von Faden und Aufgußbeutel sich auch bei hohen Temperaturen nicht löst. Ferner wird durch die Verwendung des erfindungsgemäßen Blattes ein äußerst anpaßbarer Verschluß geschaffen, der auch größere Belastungen problemlos aufnehmen kann, ohne zerstört oder beschädigt zu werden. Dies wird unter anderem durch die flächige Befestigung erreicht, welche größere Kohäsions- und/oder Adhäsionskräfte aufweist als bisher bekannte Verschlüsse.The use of a sheet of heat sealable filter paper as Head closure of the infusion bag has the essential advantage that none media and / or materials that change or influence taste indirect or direct contact with that contained in the chamber Enter the quantum of substance and may have a disruptive effect because heat-sealable filter paper no taste-changing substance having. Furthermore, complex operations for closing the Avoid tea bags. Through the flat distribution and the connection with the filter paper is also guaranteed that the connection of thread and Tea bags do not dissolve even at high temperatures. Furthermore, the Use of the sheet of the invention an extremely customizable closure created that can easily accommodate larger loads without to be destroyed or damaged. This is partly due to the areal Attachment achieved which greater cohesive and / or adhesive forces has closures than previously known.

Aus der EP-A-0 458 215 war es zwar bekannt, den Faden am Kopfende des Aufgußbeutels mittels eines mehrlagigen Blattes zu befestigen. Das Blatt besteht hierbei aus einer Lage Polyethylen zum Befestigen des Blattes am Aufgußbeutel, einer Lage Polyester, die die notwendige Festigkeit für das Blatt ergibt, und einer zweiten Lage aus Polyethylen, mit der eine Lage aus Papier gehalten wird. Außer diesem mehrschichtigen Aufbau, der im Gegensatz zum erfindungsgemäßen Filterpapier nicht durchlässig und nicht geschmacksneutral ist, erfolgt mit dem Blatt kein Verschließen des Kopfendes des Aufgußbeutels, sondern lediglich eine Befestigung des Fadens.From EP-A-0 458 215 it was known to thread the end of the Attach the infusion bag using a multi-layer sheet. The leaf exists one layer of polyethylene for attaching the sheet to the infusion bag, a layer of polyester that provides the necessary strength for the sheet, and one second layer of polyethylene that holds a layer of paper. Except this multilayer structure, which in contrast to the invention Filter paper is not permeable and not tasteless, is done with the sheet no closing of the head end of the infusion bag, only one Fastening the thread.

Das zur Befestigung verwendete Blatt aus heißsiegelfähigem Filterpapier kann dabei jede beliebige Form aufweisen, beispielsweise streifenförmig, rechteckig, viereckig, dreieckig oder kreisförmig ausgebildet sein.The sheet of heat-sealable filter paper used for attachment can have any shape, for example stripe-shaped, rectangular, be square, triangular or circular.

Gemäß einem weiteren Merkmal der Erfindung ist der Aufgußbeutel als Doppelkammer-Aufgußbeutel ausgestaltet, der zwei aus Filterpapiermaterial bestehende, Seite an Seite aneinanderliegende, jeweils ein Substanzquantum enthaltende Kammern aufweist, die durch eine Querfaltung am Boden miteinander verbunden und deren Kopfenden gemeinsam durch das Blatt aus heißsiegelfähigem Filterpapier verschlossen und aneinander befestigt sind.According to a further feature of the invention, the infusion bag is as Double chamber infusion bag designed, the two of filter paper material existing, side by side, each one quantum of substance Containing chambers, which are joined together by a transverse fold on the bottom connected and their head ends together through the sheet heat-sealable filter paper are sealed and attached to each other.

Zum Verschließen der Kammern gibt es mehrere erfindungsgemäße Ausgestaltungen. Zum einen können die Kopfenden der Kammern gemeinsam durch einen in Querrichtung verlaufenden Verschlußfalz abgeschlossen und duch ein rechteckiges Blatt befestigt sein. Zum anderen werden die Kopfenden der Kammern durch ein sich über die Länge des Kopfendes der Kammern erstreckendes, rechteckiges und mit einer Querfaltung versehenes Blatt verschlossen, das in der Art eines Reiters auf die Kopfenden der Kammern aufgesetzt ist. Schließlich ist es möglich, die mit einem in Querrichtung verlaufenden Verschlußfalz versehenen Kopfenden der Kammern durch ein als schlauchförmiger Streifen ausgebildetes Blatt zu verschließen, das über die Kopfenden geschoben ist.There are several according to the invention for closing the chambers Configurations. For one thing, the head ends of the chambers can pass through together completed a transverse locking seam and by a rectangular sheet. Secondly, the head ends of the chambers by extending over the length of the head end of the chambers Rectangular and cross-folded sheet closed in the Kind of a rider is placed on the head ends of the chambers. After all it is possible, the provided with a transverse transverse locking seam Head ends of the chambers by a tubular strip To close the sheet that is pushed over the head ends.

Vorzugsweise ist auch das Etikett am Faden durch ein Blatt aus heißsiegelfähigem Material befestigt.The label on the thread is preferably also made of a sheet of heat-sealable material Material attached.

Der in Fig. 1 dargestellte Doppelkammer-Aufgußbeutel 1 weist zwei, Seite an Seite aneinanderliegende Kammern 2 und 3 auf, die am Boden 4 über eine W-förmige Querfaltung 5 miteinander verbunden sind und jeweils ein vorgegebenes Quantum einer durch eine Aufgußflüssigkeit auszulaugender Substanz, insbesondere Tee, enthalten. Die Kopfenden der beiden Kammern 2 und 3 sind gemeinsam durch einen in Querrichtung verlaufenden Verschlußfalz 6 verschlossen und durch ein rechteckiges Blatt 7 aus heißsiegelfähigem Filterpapier aneinander befestigt. Mit dem Blatt 7 wird gleichzeitig ein Faden 8 im Bereich des Verschlußfalzes 6 des Kopfendes des Doppelkammer-Aufgußbeutels 1 befestigt.The double chamber infusion bag 1 shown in Fig. 1 has two, side by side adjacent chambers 2 and 3 on the bottom 4 via a W-shaped Cross fold 5 are connected to each other and each a predetermined quantity a substance to be leached out by an infusion liquid, in particular tea, contain. The head ends of the two chambers 2 and 3 are together through a transverse closing seam 6 closed and by a rectangular sheet 7 made of heat-sealable filter paper attached to each other. With the sheet 7 is simultaneously a thread 8 in the region of the closing fold 6 of the Attached top of the double chamber infusion bag 1.

Der Faden 8 ist an seinem anderen Ende mittels einer hier nicht explizit dargestellten Verbindung 10, beispielsweise einem Heftel oder einem Knoten, mit einem zur Handhabe und/oder Information dienenden Etikett 9 verbunden. Das Etikett 9 kann aus heißsiegelfähigem Material bestehen und der Faden direkt angesiegelt werden. Durch die Verwendung des Blattes 7 zur Befestigung des Fadens 8 mit dem Doppelkammer-Aufgußbeutel 1 ist eine Geschmacksveränderung bzw. -beeinflussung insbesondere eines Tees durch die Verbindung bzw. deren Verbindungsmedien ausgeschlossen. Darüber hinaus wird mit dem Blatt 7 aus heißsiegelfähigem Filterpapier zwischen dem Faden 8 und dem Aufgußbeutel 1 eine einfache und schnell zu fertigende Verbindung geschaffen, die gleichzeitig zum Verschließen des Aufgußbeutels 1 dient.The thread 8 is not explicit at its other end by means of one here Connection 10 shown, for example a booklet or a knot with a label 9 used for handling and / or information. The Label 9 can consist of heat-sealable material and the thread directly be sealed. By using the sheet 7 to attach the Thread 8 with the double chamber infusion bag 1 is a change in taste influencing or influencing in particular a tea through the connection or their connection media excluded. In addition, sheet 7 made of heat-sealable filter paper between the thread 8 and the infusion bag 1 created a simple and quick connection that works simultaneously serves to close the infusion bag 1.

Fig. 2 zeigt eine weitere Ausführungsform für eine erfindungsgemäße Befestigung des Fadens 8 und einen erfindungsgemäßen Verschluß eines Doppelkammer-Aufgußbeutels 1 mittels eines Blattes 7 aus heißsiegelfähigem Filterpapier. Hier ist das Blatt ein sich über die Länge des Kopfendes des Doppelkammer-Aufgußbeutels 1 erstreckendes, rechteckiges Blatt 7, welches eine Querfaltung 11 aufweist und nach Art eines Reiters am Kopfende der Kammern 2 und 3 des Doppelkammer-Aufgußbeutels 1 aufgesetzt ist und so die Kammern 2 und 3 verschließt. Dabei wird gleichzeitig der Faden 8 von der Querfaltung 11 aufgenommen und so am Doppelkammer-Aufgußbeutel 1 befestigt.Fig. 2 shows a further embodiment for a fastening according to the invention of the thread 8 and a closure according to the invention of a double-chamber infusion bag 1 by means of a sheet 7 of heat-sealable filter paper. Here is the leaf extends over the length of the head end of the double-chamber infusion bag 1 extending rectangular sheet 7, which has a transverse fold 11 has and like a rider at the head of chambers 2 and 3 of Double chamber infusion bag 1 is placed and so the chambers 2 and 3 closes. At the same time, the thread 8 is removed from the transverse fold 11 recorded and thus attached to the double chamber infusion bag 1.

Wie in Fig. 2 zu erkennen, ist hier die Verbindung 10 zwischen dem Faden 8 und dem Etikett 9 ebenfalls durch ein rechteckiges Blatt 12 aus heißsiegelfähigem Material geschaffen, welches den Faden 8 am Etikett 9 befestigt.As can be seen in Fig. 2, here is the connection 10 between the thread 8 and the label 9 also by a rectangular sheet 12 made of heat sealable Created material that attaches the thread 8 to the label 9.

Die in Fig. 3 dargestellte Variante der Befestigung des Fadens 8 im Bereich des Verschlußfalzes 6 des Doppelkammer-Aufgußbeutels 1 durch ein Blatt 7, welches gleichzeitig die Kopfenden der beiden Kammern 2 und 3 aneinander befestigt, unterscheidet sich von der in Fig. 1 dargestellten Ausführungsform durch eine andere Ausgestaltung des in Querrichtung verlaufenden Verschlußfalzes 6 der beiden Kammern 2 und 3. Im Gegensatz zu der Ausführungsform gemäß Fig. 1 ist der Kopfverschlußfalz 6 bei der Ausführungsform gemäß Fig. 3 dadurch hergestellt, daß die Kammern 2 und 3 des Doppelkammer-Aufgußbeutels 1 von den Kopfenden her nur umgelegt sind, ohne daß die Ecken vorher eingefaltet wurden.The variant shown in Fig. 3 of fastening the thread 8 in the area of Sealing fold 6 of the double-chamber infusion bag 1 by a sheet 7, which at the same time the head ends of the two chambers 2 and 3 are attached to each other, differs from the embodiment shown in Fig. 1 by a another configuration of the transverse closing fold 6 of the two chambers 2 and 3. In contrast to the embodiment according to FIG. 1 the head lock fold 6 in the embodiment according to FIG. 3 thereby made that the chambers 2 and 3 of the double-chamber infusion bag 1 of the head ends are only folded down without the corners being folded in beforehand were.

Wie in Fig. 3 zu erkennen, ist hier die Verbindung 10 zur Befestigung des Fadens 8 an dem Etikett 9 durch einen Knoten 13 gegeben. Dazu weist das Etikett 9 eine Öffnung 14 auf, durch die der Faden 8 hindurchgesteckt und durch den Knoten 13 gegen ein Herausrutschen gesichert ist.As can be seen in Fig. 3, here is the connection 10 for fastening the thread 8 given on the label 9 by a knot 13. For this purpose, the label 9 has a Opening 14 through which the thread 8 is inserted and through the knot 13 is secured against slipping out.

Bei dem in Fig. 3 alternativ gebrochen dargestellten Doppelkammer-Aufgußbeutel, von dem nur das Kopfende dargestellt ist, ist das Blatt 7 sich über die Länge des Kopfendes erstreckend als Schlauchstreifen ausgebildet, der über das Kopfende des Doppelkammer-Aufgußbeutels 1 geschoben und durch heißsiegeln, die kammern 2 und 3 verschließend und den Faden 8 befestigend, mit dem Doppelkammer-Aufgußbeutel 1 verbunden ist.In the alternative, double-chamber infusion bag shown broken in FIG. 3, of which only the head end is shown, the sheet 7 is the length of the Head end extending as a tubular strip, which over the head end of the double-chamber infusion bag 1 and heat sealed by chambers 2 and 3 closing and attaching the thread 8, with the Double chamber infusion bag 1 is connected.

Selbstverständlich lassen sich sämtliche Varianten der verschiedenen Ausführungsformen für eine Befestigung des Fadens 8 am Doppelkammer-Aufgußbeutel 1 bzw. des Fadens 8 am Etikett 9 kombinieren. Dabei lassen sich insbesondere für die Verbindung 10 zwischen dem Faden 8 und dem Etikett 9 auch die bisher gebräuchlichen Verbindungs- bzw.
