Description

Die Erfindung bezieht sich auf einen Aufgußbeutel mit einem durch eine in dessen Kopfteil vorgesehenen Ausnehmung geführten Zugfaden, der den Aufgußbeutel in Längsrichtung umgibt und mittels dem dieser auspressbar ist, wobei der Zugfaden doppelt durch die Ausnehmung des Kopfteiles hindurch gesteckt und auf einer Seite des Aufgußbeutels zu einer Schlinge geformt ist, und wobei das eine von der Schlinge abführende Teilstück des Zugfadens den Aufgußbeutel umschlingt.The invention relates to an infusion bag with one in the head part provided recess guided thread, which the infusion bag in the longitudinal direction surrounds and by means of which this can be squeezed out, the pulling thread being double through the Recess of the head part inserted through and on one side of the infusion bag a loop is formed, and wherein the one section of the loop leading away from the loop Pulling thread wraps around the infusion bag.

Dokument WO 0134486 zeigt einen derartigen Aufgußbeutel bzw. gemäß dem Oberbegriff des Anspruchs 1.Document WO 0134486 shows such an infusion bag or according to the preamble of claim 1.

Durch die nachveröffentlichte DE 100 01 003 A1 ist des weiterein ein Aufgußbeutel dieser Art bekannt. Bei dieser Ausgestaltung ist im Kopfteil des Aufgußbeutels nur eine mittig angeordnete Schlinge vorgesehen, durch die der Zugfaden einfach oder gegebenenfalls auch doppelt hindurchgeführt und um den Beutel geschlungen ist. Zwar kann durch Auseinanderziehen der von dem Aufgußbeutel abführenden Zugglieder des Zugfadens der Aufgußbeutel ausgewrungen werden, dieser ist aber in nur zwei rechteckige oder bei einer doppelten Umschlingung in drei dreieckförmige Kammern unterteilt, so daß das Auspressen des Aufgußbeutels mitunter nicht optimal zu bewerkstelligen ist. Vor allem aber ist bei beiden Ausgestaltungen von Nachteil, daß im Bereich der zur Schlingenbildung vorgesehenen Ausnehmung hohe Zugkräfte auf das Kopfteil ausgeübt werden, so daß dieses ausreißen kann und der Inhalt des Aufgußbeutels in das zubereitete Getränk gelangt, das in derartigen Fällen zusätzlich zu behandeln ist.Due to the post-published DE 100 01 003 A1 this is also an infusion bag Kind known. In this embodiment, only one is in the center of the infusion bag Arranged loop provided through which the pull thread easily or if necessary also passed twice and wrapped around the bag. Although can by Pulling apart the pulling members of the pulling thread leading away from the infusion bag Infusion bags are wrung out, but this is in only two rectangular or one double wrapping divided into three triangular chambers, so that the Squeezing the infusion bag is sometimes not optimal. Especially but is disadvantageous in both configurations that in the area of loop formation provided recess high tensile forces are exerted on the head part, so that this can tear out and the contents of the infusion bag in the prepared drink arrives, which must be treated in such cases.

Aufgabe der Erfindung ist es daher, einen Aufgußbeutel in der vorgenannten Gattung derart weiterzubilden, daß an diesem der Zugfaden nicht nur ohne metallische Klammern zu befestigen ist und ein nahezu vollständiges Ausdrücken des Aufgußbeutels mittels des Zugfadens ermöglicht wird, sondern es soll auch erreicht werden, daß der Aufgußbeutel in mehrere gleichmäßig zu bemessende Aufnahmekammern zu unterteilen ist. Vor allem aber soll gewährleitstet sein, daß ein Ausreißen im Bereich des Kopfteils des Aufgußbeutels auch bei hoher Krafteinwirkung über die Zugglieder nahezu ausgeschlossen ist. Die Handhabung beim Aufbrühen eines Aufgußbeutels soll somit weiter vereinfacht werden, auch sollen, wie bei der bereits bekannten Ausgestaltung, keine Beeinträchtigungen des aufgebrühten Tees durch Fremdkörper in Kauf zu nehmen sein.The object of the invention is therefore to provide an infusion bag in the aforementioned type to develop in such a way that the drawstring not only without metallic clips is to be attached and an almost complete expression of the infusion bag by means of Zugfadens is enabled, but it should also be achieved that the infusion bag in several receptacles to be dimensioned equally must be subdivided. But especially it should be ensured that tearing in the area of the head part of the infusion bag is almost impossible even with high force on the tension members. The Handling when brewing an infusion bag should thus be further simplified, also, as in the already known embodiment, no impairment of the brewed teas can be tolerated by foreign bodies.

Gemäß der Erfindung wird dies bei einem Aufgußbeutel der vorgenannten Art dadurch erreicht, daß das den Aufgußbeutel umschlingende Teilstück des Zugfadens durch die Schlinge zurückgeführt ist und das weitere, von der Schlinge abführende Teilstück und das durch diese hindurchgeführte Teilstück des Zugfadens jeweils Zugglieder zum Auspressen des Aufgußbeutels bilden und wobei in das Kopfteil des Aufgußbeutels zwei mit seitlichem Abstand zueinander vorzugsweise auf gleicher Höhe angeordnete Ausnehmungen eingearbeitet sind, daß der Zugfaden doppelt durch jede der Ausnehmungen hindurch gesteckt ist und zwei Schlingen gebildet sind, die über ein an dem Kopfteil des Aufgußbeutels anliegendes Zwischenstück miteinander verbunden sind, und daß die an dem Aufgußbeutel anliegenden Teilstücke des Zugfadens durch die Schlingen zurückgeführt sind und die Zugglieder bilden.According to the invention, this is done in an infusion bag of the aforementioned type achieved that the infusion bag looping portion of the thread through the Loop is returned and the further section leading away from the loop and that through this section of the tension thread passed each tension members for pressing form the infusion bag and being in the head part of the infusion bag two with side Clearances to one another, preferably arranged at the same height are incorporated in that the pull thread double through each of the recesses is plugged and two loops are formed, one over the head part of the Aufgußbeutels adjacent adapter are connected to each other, and that the sections of the pulling thread lying against the infusion bag through the loops are returned and form the tension members.

Zweckmäßig ist es hier, den seitlichen Abstand der beiden Ausnehmungen von den Längskanten des Aufgußbeutels derart zu wählen, daß bei parallel zu den Längskanten des Aufgußbeutels verlaufenden Teilstücken des Zugfadens der Aufgußbeutel beim Zusammenpressen in drei etwa gleich breit bemessene Abschnitte unterteilt ist.It is useful here, the lateral distance of the two recesses from the To choose the longitudinal edges of the infusion bag so that parallel to the longitudinal edges of the infusion bag extending portions of the drawstring of the infusion bag at Pressing together is divided into three sections of approximately the same width.

Nach andersartigen Anordnungen des Zugfadens kann dieser derart durch die beiden Schlingen und im Bereich des Bodens des Aufgußbeutels geführt sein, daß die Teilstücke des Zugfadens auf einer Seite des Aufgußbeutels kreuzweise und auf der anderen Seite parallel zu dessen Längskanten verlaufen, oder daß die Teilstücke der Zugfaden auf beiden Seiten des Aufgußbeutels kreuzweise angeordnet sind. Es ist aber auch möglich, den Zugfaden derart durch die beiden Schlingen und im Bereich des Bodens des Aufgußbeutels zu führen, daß die Teilstücke der Zugfaden auf beiden Seiten des Aufgußbeutels in Form eines Dreieckes angeordnet sind.After different arrangements of the thread, this can be done by the two Loops and be guided in the area of the bottom of the infusion bag that the sections of the drawstring crosswise on one side of the infusion bag and on the other side run parallel to its longitudinal edges, or that the sections of the pull thread are arranged crosswise on both sides of the infusion bag. But it is also possible the tension thread through the two loops and in Area of the bottom of the infusion bag to guide the sections of the drawstring are arranged on both sides of the infusion bag in the form of a triangle.

Zur Führung des Zugfadens im Bereich des Bodens des Aufgußbeutels können zwei, vorzugsweise jeweils mit etwa gleichem Randabstand wie die die Schlingen aufnehmenden Ausnehmungen, angeordnete Durchbrechungen oder bei dreieckförmig verlaufenden Teilstücke des Zugfadens eine mittig angeordneten Ausnehmung vorgesehen werden.To guide the pull thread in the area of the bottom of the infusion bag two, preferably each with approximately the same edge distance as that of the loops receiving recesses, arranged openings or at triangular sections of the pulling thread arranged in the middle Recess are provided.

Die beiden Zugglieder des Zugfadens können gemeinsam an einem Etikett angebracht bzw. einzeln mit Etiketten versehen oder durch einen Knoten fest miteinander verbunden sein.The two tension members of the tension thread can be together on a label attached or individually labeled or fixed by a knot be connected.

Wird ein Zugfaden gemäß der Erfindung an einem der Aufgußbeutel angebracht, so ist es ohne weiteres möglich, den Aufgußbeutel ohne Hilfsmittel auszuquetschen und die restliche Flüssigkeit nahezu vollständig aus diesem herauszudrücken. Dazu sind lediglich die von dem Kopfteil abgeführten Zugglieder des Zugfadens auseinander zu ziehen. Durch den in Längsrichtung doppelt und mit seitlichem Abstand um den Aufgußbeutel, der somit in drei Kammern unterteilt ist, geschlungenen Zugfaden wird nämlich der Aufgußbeutel auch 2-fach fest zusammengedrückt, so daß dessen Volumen verkleinert wird, ohne daß es dazu irgendwelcher Hilfsmittel bedarf.If a pull thread according to the invention is attached to one of the infusion bags, so it is easily possible to squeeze the infusion bag without tools and to push the remaining liquid almost completely out of it. To do this only the tension members of the tension thread removed from the head part apart pull. By the double in the longitudinal direction and with a lateral distance around the Infusion bag, which is thus divided into three chambers, becomes looped pull thread namely the infusion bag also 2 times firmly compressed, so that its Volume is reduced without the need for any tools.

Da der Zugfaden jeweils ohne Hilfsmittel an dem Aufgußbeutel gehalten ist, wird beim Aufbrühen das Aroma des Tees durch metallische Fremdkörper nicht beeinträchtigt und verfälscht. Auch wird beim Zusammenpressen des Aufgußbeutels dieser nicht beschädigt, auf diesen werden nämlich beim Auseinanderziehen der beiden Zugglieder des Zugfadens keine seitlich gerichteten Kräfte ausgeübt, diese Kräfte werden vielmehr von den Schlingen, durch die die Zugglieder hindurchgeführt sind, aufgenommen. Vor allem ist hier von Vorteil, daß durch die Anordnung von zwei Schlingen die abzustützenden Zugkräfte gewissermaßen halbiert werden. Beschädigungen im Bereich des Kopfteils des Aufgußbeutels werden somit beim Auspressen zuverlässig, auch wenn hohe Kräfte ausgeübt werden, vermieden. Mit sehr geringem Fertigungsaufwand werden demnach die Herstellung eines Aufgußbeutels und dessen Handhabung beim Aufbrühen von Getränken sehr vereinfacht. Auch ist der Zugfaden an jeder Art von Aufgußbeuteln problemlos anzubringen.Since the pull thread is held on the infusion bag without any aids When brewing, the aroma of the tea is not caused by metallic foreign bodies impaired and adulterated. Also when compressing the infusion bag this is not damaged, namely when pulling apart the no lateral forces exerted on both tension members of the tension thread, these Rather, forces are exerted by the slings through which the tension members pass are included. The main advantage here is that the arrangement of two loops the tensile forces to be supported are effectively halved. Damage in the area of the head part of the infusion bag is thus at Squeezing reliably avoided even when high forces are exerted. With very low manufacturing costs are accordingly the manufacture of a Infusion bag and its handling when brewing beverages very much simplified. The drawstring on any type of infusion bags is also easy to install.

Die in den Figuren 1 bis 6 dargestellten und mit 1 bzw. 1' bezeichneten Aufgußbeutel sind in unterschiedlicher Weise ausgebildet und jeweils mit einem Kopfteil 2 bzw. 2' versehen, an dem ein Zugfaden 11 angebracht ist. Bei der Ausgestaltung nach den Figuren 1 und 2 ist an den Enden des Zugfadens 11 ein Etikett 21 befestigt, bei der Ausgestaltung nach den Figuren 3 bis 6 sind die beiden Enden des Zugfadens 11 jeweils mit einem zweiteiligen Etikett 21', 21 " versehen.The shown in Figures 1 to 6 and designated 1 and 1 ' Infusion bags are designed in different ways and each with one Head part 2 or 2 'provided on which a pulling thread 11 is attached. In the The embodiment according to FIGS. 1 and 2 is a at the ends of the tension thread 11 Label 21 attached, in the embodiment according to Figures 3 to 6 are the two Each end of the tension thread 11 is provided with a two-part label 21 ', 21 ".

Zur Befestigung des Zugfadens 11 sind in das Kopfteil 2 bzw. 2'des Aufgußbeutels 1 bzw. 1 'jeweils zwei Ausnehmungen 4 und 5 in Form von Bohrungen eingearbeitet, durch die der Zugfaden 11 in Form von Schlingen 12 bzw. 13 zweifach hindurchgezogen ist. Die beiden Teilstücke 14 und 15 des Zugfadens 11, die über ein an dem Kopfteil 2 bzw. 2' des Aufgußbeutels 1 bzw. 1' anliegenden Teilstück 14 miteinander verbunden sind, sind im Anschluß an die Schlingen 12 bzw. 13 um den Aufgußbeutel 1 bzw. 1', und zwar um dessen Boden 3, geschlungen, sodann durch die Schlingen 12 bzw. 13 zurückgeführt und mit Abstand zu dem Aufgußbeutel 1 bzw. 1 'an dem Etikett 21 bzw. an zwei Hälften eines durch Perforation oder Einschnitte leicht zu teilenden Etiketts 21', 21 " befestigt. Die von dem Aufgußbeutel 1 bzw. 1' abführenden Teilstücke 15 und 16 bilden somit Zugglieder 17 und 18.To attach the pull thread 11, 2 or 2 ′ of the infusion bag 1 are in the head part or 1 ', two recesses 4 and 5 are machined in the form of bores, through which the pull thread 11 in the form of loops 12 and 13 twice is pulled through. The two sections 14 and 15 of the tension thread 11, the a section 14 lying against the head part 2 or 2 'of the infusion bag 1 or 1' are connected to each other, are following the loops 12 and 13 around the Infusion bag 1 or 1 ', namely around the bottom 3, looped, then through the loops 12 and 13 are returned and at a distance from the infusion bag 1 or 1 'on the label 21 or on two halves of one by perforation or Incisions easy to divide labels 21 ', 21 "attached. From the infusion bag 1 and 1 'laxative sections 15 and 16 thus form tension members 17 and 18.

Werden nach dem Aufbrühen des Aufgußbeutels 1 bzw. 1' die beiden von diesem abführenden Zuggliedern 17 und 18 des Zugfadens 11, wie dies in Figur 2 dargestellt ist, auseinandergezogen, so werden die um den Aufgußbeutel 1 bzw. 1' geführten Teilstücke 15 und 16 des Zugfadens 11 verkürzt. Der Aufgußbeutel 1 bzw. 1' wird dadurch zusammengedrückt und somit ausgewrungen, so daß die in diesem befindliche restliche Flüssigkeit, ohne daß es eines Hilfsmittels bedarf, ausgequetscht wird. Und da dieser Vorgang ohne weiteres über einem Gefäß vorgenommen werden kann, werden nicht nur die Aromastoffe des in dem Aufgußbeutel 1 bzw. 1' befindlichen Tees nahezu vollständig genutzt, sondern es werden auch Verunreinigungen durch abtropfende Flüssigkeit bei der Entsorgung des Aufgußbeutels 1 bzw. 1' vermieden.After the brewing of the infusion bag 1 or 1 ', the two of this laxative tension members 17 and 18 of the tension thread 11, as shown in Figure 2 is shown pulled apart, so that around the infusion bag 1 or 1 ' guided sections 15 and 16 of the tension thread 11 shortened. The infusion bag 1 or 1 'is thereby compressed and wrung out, so that in this remaining liquid, without the need for an aid, is squeezed out. And since this process easily over a vessel can be made, not only the flavorings of the in the Infusion bags 1 or 1 'located teas almost completely used, but it there will also be contamination from dripping liquid during disposal of the infusion bag 1 or 1 'avoided.

Um ein seitliches Abrutschen des Zugfadens 11 von dem Aufgußbeutel 1', insbesondere bei dessen Lagerung und/oder Transport, auszuschließen, sind, wie dies in Figur 3 gezeigt ist, im Bereich des Bodens 3' in den Aufgußbeutel 11' zwei Durchbrechungen 6 und 7 eingearbeitet, durch die die Teilstücke 15 und 16 hindurch gesteckt sind. Die Durchbrechungen 6 und 7 sind hierbei etwa mit dem gleichen Abstand zu den Längskanten des Aufgußbeutels 1' angeordnet wie die beiden Ausnehmungen 4 und 5, wobei die Abstände derart gewählt sind, daß beim Zusammenpressen des Aufgußbeutels 1' drei etwa gleich groß bemessene Kammern gebildet sind. Die Teilstücke 15 und 16 verlaufen demnach etwa parallel zu den Längskanten des Aufgußbeutels 1, ein Verrutschen des Zugfadens 11 ist dadurch auch bei unsachgemäßer Behandlung ausgeschlossen.In order for the pulling thread 11 to slide sideways off the infusion bag 1 ', especially when storing and / or transporting it, how this is shown in Figure 3, in the region of the bottom 3 'in the infusion bag 11' two Openings 6 and 7 are incorporated, through which the sections 15 and 16 pass are stuck. The openings 6 and 7 are approximately the same Distance to the longitudinal edges of the infusion bag 1 'arranged like the two Recesses 4 and 5, the distances being chosen such that when Compress the infusion bag 1 'three approximately the same size Chambers are formed. The sections 15 and 16 therefore run approximately parallel to the longitudinal edges of the infusion bag 1, slipping of the tension thread 11 therefore excluded even with improper handling.

Mittels des Zugfadens 11 können somit unterschiedlich gestaltete Aufgußbeutel 1 bzw. 1' ausgepreßt werden, ohne daß dabei auf diesen im Bereich der Ausnehmungen 4 und 5 hohe Kräfte ausgeübt werden. Die Zugkräfte werden vielmehr über die Schlingen 12 und 13 vollständig in den Zugfaden 11 übertragen ohne den Verschluß des Aufgußbeutels zu belasten, so daß durch Auseinanderziehen der Zugglieder 17 und 18 ein nahezu vollständiges Auspressen des Aufgußbeutels 11 gewährleistet ist.By means of the pull thread 11, differently designed infusion bags 1 can or 1 'are pressed out without this in the area of Recesses 4 and 5 high forces are exerted. The tensile forces will rather, completely transferred into the tension thread 11 via the loops 12 and 13 without straining the closure of the infusion bag, so that by Pulling the tension members 17 and 18 apart almost completely the infusion bag 11 is guaranteed.

Bei der in Figur 4 dargestellten Ausführungsvarianten sind die Teilstücke 15 und 16 des Zugfadens 11 derart durch die Schlingen 12 und 13 sowie die im Bereich des Bodens 3' in den Aufgußbeutel 1' eingearbeiteten Durchbrechungen 6 und 7 geführt, daß die Teilstücke 15 und 16 auf der einen Seite des Aufgußbeutels 1' parallel zu dessen Längskanten und auf der anderen Seite kreuzweise angeordnet sind. Gemäß Figur 5 ist aber auch eine kreuzweise Anordnung der Teilstücke 15 und 16 auf beiden Seiten des Aufgußbeutels 1' möglich.In the embodiment variants shown in FIG. 4, the sections are 15 and 16 the thread 11 through the loops 12 and 13 and in the area of Bottom 3 'in the infusion bag 1' incorporated openings 6 and 7th led that the sections 15 and 16 on one side of the infusion bag 1 ' arranged parallel to its longitudinal edges and crosswise on the other side are. According to FIG. 5, however, there is also a crosswise arrangement of the sections 15 and 16 possible on both sides of the infusion bag 1 '.

Bei dem in Figur 6 gezeigten Aufgußbeutel 1' ist in dessen Boden 3' nur eine Durchbrechung 8 mittig eingearbeitet, durch die die beiden Teilstücke 15 und 16 des Zugfadens 11 hindurchgezogen und umgelenkt sind. Der Zugfaden 11 umschlingt demnach den Aufgußbeutel 1' auf beiden Seiten in Form eines Dreiecks.In the infusion bag 1 'shown in FIG. 6, there is only one in the bottom 3' thereof Opening 8 incorporated centrally through which the two sections 15 and 16 of the Drawstring 11 are pulled through and deflected. The tension thread 11 wraps around accordingly the infusion bag 1 'on both sides in the form of a triangle.
