Description

Kunststoffverschluss  Plastic closure
Die vorliegende Erfindung betrifft einen Kunststoffverschluss zur Verwendung auf einem Schlauchbeutel mit einer Entnahmeöffnung, umfassend einen Unterteil mit einer Tülle, die über der Entnahmeöffnung angeordnet ist und einen Oberteil mit einer Kappe zum dichten Verschliessen der Tülle. The present invention relates to a plastic closure for use on a tubular bag having a dispensing opening, comprising a base with a spout disposed above the dispensing opening and an upper with a cap for sealing the spout tightly.
Auf dem Markt sind heute eine grosse Anzahl von Schlauchbeuteln vertreten, die jedoch mehrheitlich aus mehrlagigen Folien gefertigt sind, insbesondere solchen Folien, die mindestens eine Lage Papier, eine Lage Kunststoff sowie eine Lage Aluminium aufweisen. Diese Schlauchbeutel sind relativ druckfest und werden vorwiegend kubisch gestaltet . On the market today, a large number of tubular bags are represented, but the majority of which are made of multilayer films, especially those films that have at least one layer of paper, a layer of plastic and a layer of aluminum. These tubular bags are relatively pressure-resistant and are designed predominantly cubic.
Seit einiger Zeit sind jedoch auch Schlauchbeutel, die nur aus Kunststofffolie bestehen, auf dem Markt. Insbesondere sind solche Schlauchbeutel als Nachfüllbeutel für Kosmetika üblich. Schlauchbeutel, die aus reiner Kunststofffolien gefertigt sind, besitzen üblicherweise entweder gar keinen Verschluss und zur Entnahme wird lediglich ein Teil des Schlauchbeutels weggeschnitten und der Inhalt des For some time, however, tubular bags, which consist only of plastic film, on the market. In particular, such tubular bags are common as refills for cosmetics. Tubular bags, which are made of pure plastic films, usually either have no closure and for removal, only a portion of the tubular bag is cut away and the contents of the
- l - Schlauchbeutels in einen Behälter umgeleert. Alternativ sind aber auch Schlauchbeutel aus Kunststoff vorhanden, die einen Flansch mit Ausgusstülle aufweisen und darauf angebracht ein reiner Schraubverschluss . Da wie bereits erwähnt, diese Schlauchbeutel entweder nur einmal oder jedenfalls nur wenige Male geöffnet und geschlossen werden müssen, kommen meist nur Schraubverschlüsse zur Anwendung. KunststoffVerschlüsse bestehend aus einem Unterteil mit einer Tülle und einer am Unterteil über ein Scharnier verbundenen Kappe, sind auf dem Markt in beliebig vielen Varianten erhältlich, doch deren Anbringung auf Schlauchbeuteln kommt nicht in Frage. Schlauchbeutel aus Kunststoff sind hoch flexibel und entsprechend wirken auf diese, während des Transportes und dem Handling relativ grosse Kräfte, die zur Verformung der Schlauchbeutel führen und entsprechend den Innendruck erhöhen. Reine Scharnierverschlüsse vermögen diesen Kräften üblicherweise nicht standzuhalten. Aus Sicherheitsgründen kommen daher bis heute auf Schlauchbeuteln meist nur KunststoffVerschlüsse der eingangsgenannten Art zum Einsatz. - l - Tube bag changed into a container. Alternatively, however, tubular bags are made of plastic, which have a flange with spout and attached to a pure screw. Since, as already mentioned, these tubular bags either only once or at least only a few times must be opened and closed, usually only screw caps are used. Plastic closures consisting of a lower part with a spout and a cap connected to the lower part via a hinge are available on the market in any number of variants, but their attachment to tubular bags is out of the question. Plastic bag made of plastic are highly flexible and act accordingly on this, during transport and handling relatively large forces that lead to deformation of the tubular bag and increase accordingly the internal pressure. Pure hinged closures are usually unable to withstand these forces. For safety reasons, therefore, only plastic closures of the type mentioned initially are usually used on tubular bags.
Die Anmelderin wird nun Schlauchbeutel aus reiner Kunststofffolie auf den Markt bringen, die als Trinkbehältnis geeignet sein sollen. Dies verlangt, dass solche Schlauchbeutel mit einem Kunststoffverschluss versehen sind, die zum schnellen Öffnen und Schliessen mit einem Scharnierverschluss versehen sind, der jedoch so angepasst ist, dass er auch höheren Drücken standhalten kann, ohne dabei an Schliesskraft zu verlieren. Diese Aufgabe löst ein Kunststoffverschluss gemäss Oberbegriff des Patentanspruches 1, der sich dadurch auszeichnet, dass die Kappe direkt schraubbeweglich mit der Tülle verbindbar und indirekt schwenkbar auf die Tülle auf und zu klappbar gehalten ist. The Applicant will now bring tubular bags made of pure plastic film on the market, which should be suitable as a drinking container. This requires that such tubular bags are provided with a plastic closure, which are provided with a hinged closure for quick opening and closing, but which is adapted so that it can withstand even higher pressures, without in the process of losing grip. This object is achieved by a plastic closure according to the preamble of claim 1, which is characterized in that the cap is directly schraubbeweglich connected to the spout connectable and indirectly pivotally held on the spout on and to fold.
Bevorzugterweise wird die Tülle als Trinktülle gestaltet mit einem zylindrischen Teil, an dem ein verjüngender, gewölbt konischer Teil anschliesst, wobei der zylindrische Teil mit einem zur Verbindung mit dem Schlauchbeutel geeigneten Flansch versehen ist. Solche Trinktüllen sind als Unterteil auf Kunststoffflaschen bekannt, besitzen dann jedoch keinen Flansch zur Kleb- oder Schweissverbindung auf einen Schlauchbeutel . Preferably, the grommet is designed as a drinking spout with a cylindrical part, to which a tapered, curved conical part connects, wherein the cylindrical part is provided with a suitable for connection to the tubular bag flange. Such drinking spouts are known as the lower part of plastic bottles, but then have no flange for gluing or welding connection to a tubular bag.
Prinzipiell wäre es auch denkbar, die Kappe direkt mit der Tülle beziehungsweise dem Flansch des Unterteiles zu verbinden über ein relativ langes, sogenanntes Schlackerband. Solche Bänder dienen lediglich als Verlustsicherung, haben jedoch keine Wirkung auf die Schliessbewegung . Deshalb wird hier vorgeschlagen, die Kappe über ein Spannband mit einem Haltering zu verbinden, der auf dem zylindrischen Teil der Tülle drehbar und axial fixiert gehalten ist. Besonders vorteilhaft gestaltet man den erfindungsgemässen Kunststoffverschluss derart, dass beim Abschluss der öffnenden Schraubbewegung die Unterkante der Kappe zumindest im Bereich nahe des Überganges vom zylindrischen in den verjüngenden, gewölbt konischen Teil der Tülle gelangt. Diese Lösung ist insbesondere dann von Vorteil, wenn bei der öffnenden Schraubbewegung der Kappe, das Spannband von einer annähernd gestreckten, ungespannten Lage in eine vollständig gestreckte, gespannte Lage kommt. Wird nun die Schwenkbewegung durchgeführt, so wird nun die Unterkante der Kappe entlang dem verjüngenden, gewölbt konischen Teil der Tülle entlang einer erzeugenden Linie dieses Rotationskörpers geführt, wobei beim Öffnen und Schliessen eine Schnappbewegung der Kappe erzielt wird. In principle, it would also be conceivable to connect the cap directly to the grommet or to the flange of the lower part via a relatively long, so-called Schlackerband. Such bands serve only as a loss of security, but have no effect on the closing movement. Therefore, it is proposed here to connect the cap via a tension band with a retaining ring which is rotatably and axially fixed on the cylindrical part of the spout. It is particularly advantageous to design the plastic closure according to the invention in such a way that at the conclusion of the opening screw movement the lower edge of the cap is at least in the area near the transition from the cylindrical to the tapered, curved conical part of the spout passes. This solution is particularly advantageous if during the opening screwing movement of the cap, the clamping band comes from an approximately stretched, untensioned position in a fully stretched, tensioned position. Now, if the pivoting movement is performed, then the lower edge of the cap is guided along the tapered, curved conical part of the spout along a generating line of this rotating body, wherein when opening and closing, a snap movement of the cap is achieved.

Der Kunststoffverschluss wird insgesamt mit 1 bezeichnet. Der Kunststoffverschluss 1 besteht aus einem Unterteil 2, der auf einem Schlauchbeutel 4 angebracht wird und einen Oberteil 3 der mit dem Unterteil 2 verbindbar ist. The plastic closure is designated overall by 1. The plastic closure 1 consists of a lower part 2, which is mounted on a tubular bag 4 and an upper part 3 which is connectable to the lower part 2.
Der hier gezeigte Schlauchbeutel 4 besteht aus einer reinen Kunststofffolie und ist hier als Schlauchbeutel mit einem Giebeldach realisiert. Selbstverständlich lässt sich der erfindungsgemässe Kunststoffverschluss auch auf anderen Schlauchbeuteln anbringen unabhängig von deren Form und Materialwahl. Der erfindungsgemässe Kunststoffverschluss ist jedoch geeignet und hierzu ausgelegt, um auf Schlauchbeuteln aus relativ hoch flexiblen Materialien angebracht zu werden, um sicher zu stellen, dass der Verschluss auch bei hohem Innendruck sich nicht selbsttätig öffnet. The tubular bag 4 shown here consists of a pure plastic film and is realized here as a tubular bag with a gable roof. Of course, the plastic closure according to the invention can also be applied to other tubular bags, irrespective of their shape and choice of material. However, the plastic closure according to the invention is suitable and designed for this purpose to be applied to tubular bags made of relatively highly flexible materials, to make sure that the closure does not open automatically even at high internal pressure.
Der Schlauchbeutel weist eine Entnahmeöffnung 5 auf, welche in die Folie des Schlauchbeutels 4 eingestanzt ist. Der Unterteil 2 ist entsprechend so ausgerichtet, dass dieser relativ exakt über dieser Öffnung zu liegen kommt und wird auf der Folie entweder aufgeklebt oder aufgeschweisst . Falls eine Schweissverbindung realisiert werden soll, so versieht man den Unterteil mit entsprechenden Schweissleitelementen 24. The tubular bag has a removal opening 5, which is stamped into the film of the tubular bag 4. The lower part 2 is correspondingly aligned so that it comes to rest relatively precisely over this opening and is either glued or welded on the film. If a welding connection is to be realized, then one provides the lower part with corresponding welding guide elements 24.
Der Unterteil 2 des Kunststoffverschlusses 1, der in der Figur 3 im Detail dargestellt ist, besteht im wesentlichen aus einem umlaufenden, ringförmigen Flansch 20, der auf seiner Unterseite die bereits erwähnten Schweissleitelemente 24 aufweist. Vom Flansch 20 zur Trinkmündung 28 hin, ist eine Tülle 21 vorhanden. Diese Tülle 21 ist hier als sogenannte Trinktülle gestaltet. Die Tülle 21 besitzt einen unteren, vom Flansch aus nach oben gerichteten ersten, zylindrischen Teil 22, dem sich ein verjüngender, gewölbter, konischer Teil 23 anschliesst. Am zylindrischen Teil 22 der Tülle 21 ist ein umlaufendes Formschlussmittel 25 ein- beziehungsweise angeformt. Dieses umlaufende Formschlussmittel kann beispielsweise ein, wie hier in der Figur 3 dargestellt, Haltehub sein oder etwa an derselben Lage eine umlaufende Haltewulst. Insbesondere wenn es sich hierbei um eine Haltewulst handelt, kann diese auch in Teilabschnitte unterteilt sein, so dass die Haltewulst nicht durchgehend verlaufend gestaltet ist. Oberhalb des umlaufenden Formschlussmittels 25 aber immer noch im Bereich des zylindrischen Teiles 22 der Tülle 21, verläuft ein Aussengewinde 26. Dieses Aussengewinde 26 kann aus einem einzigen Gewindegang bestehen, der relativ flach verläuft und sich um annähernd 360° erstreckt oder auch aus mehreren kürzeren Gewindegangabschnitten, die entsprechend steiler gestaltet sind, sodass mit einem geringeren Verdrehwinkel derselbe Hub erzielt wird. The lower part 2 of the plastic closure 1, which is shown in detail in Figure 3, consists essentially of a circumferential, annular flange 20 having on its underside the already mentioned Schweissleitelemente 24. From the flange 20 to the mouth 28, a spout 21 is present. This spout 21 is designed here as a so-called drinking spout. The spout 21 has a lower, upwardly directed from the flange first cylindrical portion 22, which is followed by a tapered, curved, conical part 23. On the cylindrical part 22 of the nozzle 21, a circumferential positive-locking means 25 is formed or formed. This circumferential positive locking means may be, for example, a retaining stroke, as shown here in FIG. 3, or a peripheral retaining bead approximately at the same position. Especially if this is a Holding bead acts, this can also be divided into sections, so that the retaining bead is not designed to be continuous. Above the encircling form-fitting means 25 but still in the region of the cylindrical part 22 of the spout 21, an external thread 26 extends. This external thread 26 may consist of a single thread, which extends relatively flat and extends approximately 360 ° or from several shorter thread sections , which are designed steeper so that the same stroke is achieved with a smaller angle of rotation.
Oberhalb des zylindrischen Abschnittes 22 schliesst ein nach oben verjüngender, gewölbter und somit auch konischer Teil 23 an. Dieser Teil 23 der Tülle stellt jenen Teil dar, den der Benutzer beim Trinken in den Mund oder an den Mund führt. Der obere Rand dieses konischen Teiles 23 ist mit einer Abschlusswulst 27 versehen, die im wesentlichen als Verletzungsschutz für den Benutzer dient. Die Tülle, die oben offen ist, weist entsprechend eine Trinkmündung 28 auf. Die Trinkmündung 28 besitzt vorzugsweise einen nach innen und unten hinabgezogene, umlaufende, ringförmige Dichtwand 29 auf. Diese Dichtwand 29 wirkt mit einer entsprechenden Dichtung mit der Kappe 40 zusammen. Der sogenannte Oberteil ist für sich in der Figur 4 in einer vollständig geöffneten, der Herstellungslage entsprechenden Form dargestellt. Der Oberteil besteht im Wesentlichen aus drei Elementen, nämlich zum einen aus einem Haltering 30 und zum anderen aus einer Kappe 40, wobei beide Teile über ein drittes Element, nämlich einem Spannband 31 miteinander verbunden sind. Statt eines einzigen Spannbandes können auch zwei parallel verlaufende, relativ nahe beieinander angeordnete Spannbänder 31 vorhanden sein, womit eine etwas erhöhte Schnappwirkung beim Öffnen und Schliessen des Verschlusses erzielt wird. Above the cylindrical portion 22 includes an upwardly tapering, curved and thus conical part 23 at. This part 23 of the spout represents that part which the user is leading while drinking in the mouth or mouth. The upper edge of this conical part 23 is provided with a Abschlusswulst 27, which essentially serves as injury protection for the user. The spout, which is open at the top, accordingly has a drinking mouth 28. The drinking mouth 28 preferably has an inwardly and downwardly drawn down, circumferential, annular sealing wall 29. This sealing wall 29 cooperates with the cap 40 with a corresponding seal. The so-called upper part is shown in FIG. 4 in a completely open form corresponding to the production position. The upper part consists essentially of three elements, namely on the one hand from a retaining ring 30 and the other from a cap 40, wherein both parts via a third element, namely a tension band 31 are interconnected. Instead of a single tightening strap, it is also possible for two tensioning straps 31, which run parallel to one another and are arranged relatively close to one another, to be provided, thus achieving a somewhat increased snap action when the closure is opened and closed.
Der Haltering 30 besteht im Wesentlichen aus einer zylindrischen Ringwand 32. Diese zylindrische Ringwand 32 ist weniger hoch als der zylindrische Teil 22 der Tülle 21. Der Haltering 30 deckt im Normalfall etwa 50 - 75% des zylindrischen Teiles 22 der Tülle 21 ab. Auf der Innenseite der zylindrischen Ringwand 32 erkennt man ein umlaufendes Formschlussmittel 33, welches hier als Rückhaltewulst realisiert ist. Diese Rückhaltewulst 33 hat im Querschnitt die Form eine Sägezahnes. Das entsprechende umlaufende Formschlussmittel 25 am Unterteil 2, ist im Querschnitt entsprechend gegengleich gestaltet. Selbstverständlich können die Formschlussmittel 25 und 33 auch vertauscht sein, wie zuvor beschrieben, das heisst im Haltering könnte eine entsprechende Nut auf der Innenseite angebracht sein und am zylindrischen Teil 22 der Tülle 21 könnte entsprechend eine umlaufende Wulst vorhanden sein und auch hier könnte diese Haltewulst einen sägezahnartigen Querschnitt aufweisen. Da normalerweise die Wandstärke der Tülle 21 grösser ist als die Wandstärke des Halteringes 30, wird man jedoch die Anordnungen der Haltemittel, wie hier dargestellt, wählen. The retaining ring 30 consists essentially of a cylindrical annular wall 32. This cylindrical annular wall 32 is less high than the cylindrical portion 22 of the spout 21. The retaining ring 30 covers normally about 50-75% of the cylindrical portion 22 of the spout 21 from. On the inside of the cylindrical annular wall 32 can be seen a circumferential positive locking means 33, which is realized here as a retaining bead. This retaining bead 33 has the shape of a sawtooth in cross section. The corresponding peripheral positive locking means 25 on the lower part 2, is designed in accordance with the same cross-section. Of course, the positive locking means 25 and 33 may also be reversed, as described above, that is, in the retaining ring, a corresponding groove could be mounted on the inside and on the cylindrical portion 22 of the spout 21 could accordingly a circumferential bead be present and also here this retaining bead could have a sawtooth cross-section. Since normally the wall thickness of the spout 21 is greater than the wall thickness of the retaining ring 30, but you will choose the arrangements of the holding means, as shown here.
Ferner erkennt man am Haltering 30 eine in der zylindrischen Ringwand 32 angebrachte Ausnehmung 34. Der Ausnehmung 34 diametral gegenüberliegend ist aussen am Haltering 30 eine Ansatzstelle 35 angeformt, an dem das bereits erwähnte Spannband 31 angreift. Nahe der Ansatzstelle 35, kann das Spannband zusätzlich noch mit einem Filmscharnier 36 versehen sein. In gleicher Weise ist das Spannband 31 wiederum über eine Ansatzstelle 35 an der Kappe 40 angeformt und auch hier kann ein entsprechendes Filmscharnier vorhanden sein. Furthermore, it can be seen on the retaining ring 30, a recess 34 mounted in the cylindrical annular wall 32. The recess 34 diametrically opposite the outside of the retaining ring 30 is formed an attachment point 35 on which the aforementioned clamping band 31 engages. Near the attachment point 35, the tension band may additionally be provided with a film hinge 36. In the same way, the clamping band 31 is in turn formed on a point of attachment 35 on the cap 40 and also here, a corresponding film hinge may be present.
Die Kappe 40 des Oberteiles 3 besitzt eine Mantelwand 41, die im Prinzip rein zylindrisch gestaltet sein kann, hier jedoch aus ästhetischen Gründen etwas der Formgebung der Tülle gleicht, geht in eine Deckfläche 42 über. Auf der Innenseite dieser Deckfläche 42 erkennt man eine ringförmig, senkrecht davon abstehende Wand 43 auf, welche eine Dichtung darstellt, welche entsprechend dichtend auf der Innenseite der Dichtwand 29 der Tülle 21 in deren Mündung 28 hineinzuragen kommt, wenn der Verschluss geschlossen ist. Diese Dichtung 43 wird in der Fachsprache meist als Dichtolive bezeichnet. Entsprechend ist diese etwas auf der Aussenseite gewölbt oder mit entsprechenden Dichtlippen versehen. The cap 40 of the upper part 3 has a jacket wall 41, which may be designed purely cylindrical in principle, but here, for aesthetic reasons, something resembles the shape of the spout, is in a top surface 42 on. On the inside of this top surface 42 can be seen on an annular, perpendicularly projecting wall 43, which is a seal, which in accordance with sealing on the inside of the sealing wall 29 of the spout 21 hineinzieuragen in the mouth 28 when the shutter is closed. This seal 43 is usually referred to in the jargon as a sealing olive. Corresponding is this arched on the outside or provided with appropriate sealing lips.
Bedeutend ist jedoch, dass die Kappe 40 auf der Innenseite der Mantelwand 41 mit einem Innengewinde 48 versehen ist. Hiermit wird die Kappe 40 zu einer Schraubkappe, obwohl der Oberteil gesamthaft ein Scharnierverschluss bildet. Dieser Scharnierverschluss hat eine Kappe und einen als Haltering 30 gestalteten Verschlussunterteil, der aber das Spannband 31 mit der Kappe 40 verbunden ist. Significantly, however, that the cap 40 is provided on the inside of the jacket wall 41 with an internal thread 48. Hereby, the cap 40 becomes a screw cap, although the top part collectively forms a hinge closure. This hinge closure has a cap and designed as a retaining ring 30 closure bottom part, but the tension band 31 is connected to the cap 40.
An der Unterkante 47 der Mantelwand 41 ist über Sollbruchstellenbrücken 44 ein Garantieelement 45 in Form eines Schilds 45 angeformt. An diesem Garantieelement beziehungsweise Schild 45, ist eine Abreisslasche 46 einstückig angeformt. Das Schild 45 weist auf einer Innenseite wiederum einen Teil eines Formschlussmittels auf, welches im montierten Zustand des Verschlusses in das entsprechende Formschlussmittel 25 des Unterteiles eingreift. At the lower edge 47 of the jacket wall 41, a guarantee element 45 in the form of a shield 45 is formed via predetermined breaking point bridges 44. At this warranty element or shield 45, a tear-off tab 46 is integrally formed. The shield 45 has on an inner side again a part of a positive locking means, which engages in the assembled state of the closure in the corresponding positive engagement means 25 of the lower part.
Für die Montage des erfindungsgemässen Verschlusses wird der Oberteil, der wie in der Figur 4 dargestellt, hergestellt worden ist, erst geschlossen, das heisst, dass die zylindrische Ringwand 32 des Halteringes 30 kommt fluchtend unter der Unterkante 47 der Kappe 40 zu liegen, und wird danach auf den Unterteil 2 aufgesetzt. Der Unterteil 2 kann bereits auf einen noch leeren Schlauchbeutel aufgeschweisst sein oder auch mit dem bereits aufgesetzten Oberteil 3 zusammen auf den leeren Schlauchbeutel aufgesetzt und verklebt oder verschweisst werden. Bei der Öffnung des erfindungsgemässen Verschlusses, dreht man zuerst die Kappe 40, wobei sich gleichzeitig der Haltering 30 mitdreht. Bei dieser Drehbewegung führt die Kappe 40 eine axiale Bewegung aus, während der Haltering 30 keine axiale Bewegung durchführt. Entsprechend wird das Spannband 31 vollständig gestreckt und gespannt. Ist diese Schraubbewegung der Kappe durchgeführt, so kommt die untere Kante 47 der Mantelwand 41 der Kappe 40 etwa auf der Höhe des Überganges vom zylindrischen Teil 22 zum verjüngenden, gewölbten konischen Teil 23 zu liegen. Vorgängig hat man jedoch bereits mit Hilfe der Abreisslasche 46 die Sollbruchstellen 44 zerstört und somit das Schild 45 abgerissen, sodass keine Formschlussverbindung zwischen der Kappe 40 und dem Unterteil 2 mehr besteht. Prinzipiell lässt sich aber die Kappe auch ohne vorheriges Abreissen des Garantieelementes 45 öffnen, da die hier bei auftretenden, relativen, axialen Verschiebungen zwischen der Kappe 40 und dem Haltering 30 genügen, um die Sollbruchstellenbrücken 44 zu zerstören. Dies verlangt allerdings einen grösseren Kraftaufwand. In beiden Fällen wird hierdurch jedoch der Schild 45 wegfallen und das Garantieelement hat seine Unversehrtheitsfunktion ausgeübt . Nach Beendigung der Schraubbewegung an der Kappe 40 lässt sich nun diese problemlos schwenken. Hierbei gleitet die Unterkante 47 im Bereich der dem Garantieelement diametral gegenüberliegt entlang einer erzeugenden Mantellinie der Tülle 21 im verjüngten, gewölbten, konischen Teil 23 entlang der Tülle. Hierdurch findet eine gesteuerte Öffnungsfunktion statt, während gleichzeitig das Spannband 31 praktisch als Teil eines Schnappscharnieres wird, eines Verschlusses mit einer virtuellen, sich verschiebenden Drehachse. For the assembly of the closure according to the invention, the upper part, which has been produced as shown in FIG. 4, is first closed, that is to say that the cylindrical annular wall 32 of the retaining ring 30 comes to rest flush below the lower edge 47 of the cap 40, and becomes then placed on the lower part 2. The lower part 2 can already be welded onto a still empty tubular bag be or even placed with the already attached shell 3 together on the empty tube bag and glued or welded. When the closure according to the invention is opened, the cap 40 is first turned, with the retaining ring 30 also rotating at the same time. During this rotational movement, the cap 40 performs an axial movement, while the retaining ring 30 performs no axial movement. Accordingly, the tension band 31 is completely stretched and tensioned. If this screwing movement of the cap is carried out, then the lower edge 47 of the jacket wall 41 of the cap 40 comes to rest approximately at the level of the transition from the cylindrical part 22 to the tapered, curved conical part 23. Previously, however, the breaking points 44 have already been destroyed with the help of the tear-off tab 46 and thus the sign 45 has been torn off so that there is no longer any positive connection between the cap 40 and the lower part 2. In principle, however, the cap can be opened without prior tearing off of the guarantee element 45, since the occurring here, relative, axial displacements between the cap 40 and the retaining ring 30 to destroy the predetermined breaking point bridges 44. However, this requires a greater effort. In both cases, however, this will remove the shield 45 and the guarantee element has exercised its integrity function. After completion of the screwing on the cap 40 can now swing this easily. Here, the lower edge 47 slides in the region of the guarantee element diametrically opposite along a generating generatrix of the spout 21 in the tapered, curved conical portion 23 along the spout. As a result, a controlled opening function takes place, while at the same time the clamping band 31 becomes practically part of a snap hinge, a closure with a virtual, shifting axis of rotation.
Beim Schliessen des erfindungsgemässen Verschlusses findet der umgekehrte Ablauf der zuvor beschriebenen Öffnungsbewegung statt. Dank dieser ungewöhnlichen Kombination erzielt man diverse Vorteile. Setzt man den erfindungsgemässen Verschluss vor dem Anbringen auf den Schlauchbeutel wie zuvor beschrieben erst zusammen und schweisst danach diesen auf den noch nicht völlig fertig gestellten Schlauchbeutel auf, so kann danach der Schlauchbeutel gefüllt und schliesslich durch eine Schweissung verschlossen werden, sodass man eine aseptische Füllung des Schlauchbeutels garantieren kann. Des Weiteren erhält man einen Schlauchbeutel mit einem Verschluss, der einerseits hohen Innendrücken standhält und andererseits aber auch einen gewünschten Trinkkomfort, sowie eine gesicherte Wiederverschliessung des Beutels erlaubt. Während des Trinkens genügt es, lediglich die Schraubkappe auf und zu zuklappen, will man jedoch den nicht vollständig geleerten Schlauchbeutel transportieren oder im Kühlschrank aufbewahren, so wird man die Schraubbewegung durchführen und damit die gesicherte Position erreichen. Der erfindungsgemässe Verschluss kombiniert folglich in perfekter Weise einen herkömmlichen Schraubverschluss mit einem bekannten Schnappscharnierverschluss . When closing the closure according to the invention, the reverse sequence of the opening movement described above takes place. Thanks to this unusual combination, you get several advantages. If the closure according to the invention is first put together before being applied to the tubular bag as described above and then welded onto the tubular bag which has not yet been completely finished, then the tubular bag can be filled and finally closed by welding, so that an aseptic filling of the tube is obtained Tubular bag can guarantee. Furthermore, you get a tubular bag with a closure that withstands high internal pressures on the one hand and on the other hand also allows a desired drinking comfort, as well as a secure reclosure of the bag. While drinking, just open the screw cap but if you want to transport the not completely emptied tubular bag or store in the refrigerator, so you will perform the screwing and thus reach the secured position. The inventive closure thus perfectly combines a conventional screw cap with a known snap hinge closure.
