Definitions
- the present invention relates to a plastic closure according to the preamble of claim 1.
- a plastic closure is known from the document JP 3 61180961 U known.
- a DosierverParkppe from the EP-A-0286843 known in which on the container neck a connectable part is screwed, which has an external thread on which the designed as a dosing cup screw cap is screwed.
- the connecting part itself has an intermediate bottom and in this intermediate bottom a plurality of openings are provided which are intended to serve as an outlet and on the other hand as a return or for the intake of air on the one hand.
- the present inventive solution is designed for a designed as a tubular bag container.
- Such soft packaging poses new problems. Since these problems have not been solved so far, no soft packages are on the market, which have a cap that is designed as a dosing cup. On the one hand, such soft packs have no bottleneck and thus a dosing cup can not be mounted on the bottleneck.
- such soft packaging have a connectable to the container part with external thread, which is usually designed as a simple spout with a terminal flange and allow this flange by means of ultrasound réelleschweiissen on the film of the soft packaging.
- the soft packaging is slightly deformed during handling, especially when it is still full, by gripping and accordingly increases the level of the liquid up into the closure area. If you put a return, as usual, at the lowest point, so this effect would be favored.
- the present invention has therefore set itself the task to improve a plastic closure of the type mentioned above so that it is particularly suitable for soft packaging, especially tubular bag, and overcomes the aforementioned disadvantages.
- a plastic closure of this kind with the features of the preamble is characterized in that the sleeve part connectable to the container has a weldable connection to a container designed as a tubular bag serving flange and the cap wall is provided with a circumferential collar in which an internal thread is arranged , wherein the cap on the spout of the connectable with a container Tüllenteils by means of an external thread is screwed, being arranged on the outside of the cap shell wall, in the area covered by the collar, a circumferential sealing bead as the first seal and a remaining flat surface on an upper Edge of the spout is designed as a deformable press seal and forms a second seal.
- the plastic closure is designated overall by 1. It consists of two parts, namely a spout part 2 and a cap 3 which can be screwed onto it. This entire closure in the assembled state is in the FIG. 1 shown. To explain the Tüllenmaschines 2 is now on the FIG. 2 refer.
- the Tüllenteil 2 consists of the actual spout 20, which corresponds to a cylindrical pipe section and terminally has a flange 23.
- the spout 20 has on the outside of its jacket wall 22 an external thread 21st With respect to the lower edge of the spout 20 offset upwards, and thus above the plane in which the flange 23 extends, an annular connecting wall 24 is radially inwardly formed from the inside of the shell wall 22 formed.
- This connecting wall 24 connects the casing wall 22 with a beak-shaped spout 25.
- This spout is thus arranged concentrically within the casing wall 22 of the spout 20.
- the spout 25 is formed by a cylindrical pipe section which is cut inclined to the center axis Z.
- This center axis is the common center axis for both the spout 20 and for the spout 25.
- the aforementioned connecting wall 24 extends' perpendicular to this connection axis Z.
- the spout 25 is sized in height so that the beak-shaped spout 25 with its tip the shell wall 22 of the spout 20 at least by the width of the distance between the jacket wall 21 and the wall of the spout 25 surmounted.
- the beak-shaped spout 25 is formed from a cylindrical pipe section. He thus has a cylindrical jacket wall 26.
- the tip 27 of the beak-shaped spout 25 lies on the longest generatrix.
- the spout 25 is provided with a reflux opening 28.
- This reflux opening 28 may, in principle, be designed as a window, but in the embodiment illustrated and preferred here this reflux opening 28 designed as a vertically extending, slot-shaped recess. This solution is particularly preferred because in this way the entire sleeve part 2 can be manufactured without a slider.
- the cap 3 is described below with reference to FIGS Figures 3 and 5 described.
- the cap 3 consists of a cylindrical cap shell wall 30, which is closed off by a cover surface 31. Slightly above the center, a circumferential, concentrically arranged collar 32 is integrally formed on the cap casing wall 30. This collar 32 has an internal thread 33. This internal thread 33 is adapted to the external thread 21 on the spout 20.
- the connection of the collar 32 is selected so that the cap shell wall 30 ends shortly above the connecting wall 24 in the fully screwed-on state. Accordingly, a Anschlagungswulst 29 is formed on the outer surface of the jacket wall 22 of the spout.
- the plastic closure according to the invention is used for attachment to a tubular bag.
- the flange 23 is used by means of which the plastic closure 1, for example, with ultrasound, on the plastic film of the tubular bag is weldable. Thanks to the double-walledness of the sleeve part 2, formed from the spout 20 and the beak-shaped spout 25 concentrically attached thereto with the connecting wall 24, results in an increased stability. Accordingly, this stability no longer needs to be increased by the flange 23, and thus the flange 23 can be made extremely thin-walled. This thinness of the flange 23 facilitates the welding and reduces the welding time.
- the wall thickness of the flange 23 is preferably made thinner by 20-40% than the lateral wall 22 of the spout 20.
- cap 3 also has a stabilizing effect. This is because the cap skirt wall 30 is dimensioned so that it practically engages in the spout 20 with a minimal undersize.
- the reflux opening 28 is not only above the plane in which the flange 23 extends, but also above the plane in which the annular connecting wall 24 extends. This ensures that in a completely filled tubular bag, just by the same, not already a certain amount of the tubular bag contents in the trough-shaped gap between the casing wall 22 of the spout and the spout 25 passes. Nevertheless, it can happen, especially if the user squeezes the tubular bag too tightly, that liquid comes into this area. However, as soon as he realizes this and reduces the pressure somewhat, a large part of the liquid will flow back through the reflux opening 28. This remainder, now remains in this annular trough will remain at a conventional spout angle in this area.
- FIG. 6 In contrast to rigid vessels, such as plastic bottles or glass bottles, considerably higher internal pressures can occur in tubular bags and correspondingly higher requirements for tightness must be met. This is on the FIG. 6 directed.
- the cap skirt wall 30 In the FIG. 6 one recognizes the cap skirt wall 30 in the region in which the collar 32 already described is formed. In this area, which is covered by the collar 32, a sealing bead 35 is formed on the cap shell wall 30. In the closed state of the closure, this sealing bead 30 presses on the inside of the shell wall 22 of the spout 20. The higher the pressure is within the tubular bag and thus built within the cap 3, the more presses the sealing bead 35 on the shell wall 22 of the Spout.
- the diameter in the region of the sealing bead 35 must be greater than the inner diameter of the spout 20 or In order to still be able to close this closure with reasonable effort, the shell wall of the spout in the region of the upper edge is provided with a chamfer 36.

Description
Die vorliegende Erfindung betrifft einen Kunststoffverschluss gemäß dem Oberbegriff des Anspruchs 1. Ein solchen Verschluss ist aus dem Dokument
Vor rund 30 Jahren haben sich die flüssigen Waschmittel und Weichspüler auf dem Markt durchgesetzt. Diese wurden in Kunststoffflaschen angeboten, und mit Schraubkappen verschlossen, die als Dosierbecher gestaltet sind. Aus der
In Abwandlung davon ist eine Dosierverschlusskappe aus der
Letztlich sind noch zwei weitere Dokumente bekannt, die Lösungen mit sehr ähnlichem Aufbau zeigen. In der
Während bei den bisherigen Lösungen diese immer konzipiert sind für Flaschen oder Kunststoffflaschen, die eine relativ feste Struktur haben, ist die vorliegende erfindungsgemässe Lösung für ein als Schlauchbeutel gestaltetes Behältnis ausgelegt. Bei solchen Weichverpackungen stellen sich neue Probleme. Da diese Probleme bisher nicht gelöst waren, sind bisher auch keine Weichverpackungen auf dem Markt, die eine Kappe aufweisen, die als Dosierbecher gestaltet ist. Zum einen haben solche Weichverpackungen keinen Flaschenhals und somit kann auch ein Dosierbecher nicht auf dem Flaschenhals befestigt werden.While in the previous solutions they are always designed for bottles or plastic bottles, which have a relatively strong structure, the present inventive solution is designed for a designed as a tubular bag container. Such soft packaging poses new problems. Since these problems have not been solved so far, no soft packages are on the market, which have a cap that is designed as a dosing cup. On the one hand, such soft packs have no bottleneck and thus a dosing cup can not be mounted on the bottleneck.
Üblicherweise, haben solche Weichverpackungen eine mit dem Behältnis verbindbaren Teil mit Aussengewinde, das üblicherweise als einfacher Ausguss mit endständigem Flansch gestaltet ist und es erlauben diesen Flansch mittels Ultraschall auf die Folie der Weichverpackung aufzuschweissen. Die Weichverpackung wird beim Handhaben, insbesondere wenn diese noch voll ist, durch das Ergreifen leicht deformiert und entsprechend steigt der Pegel der Flüssigkeit an bis in den Verschlussbereich. Würde man einen Rücklauf, wie sonst üblich, am tiefsten Punkt anbringen, so würde dieser Effekt noch begünstigt.Usually, such soft packaging have a connectable to the container part with external thread, which is usually designed as a simple spout with a terminal flange and allow this flange by means of ultrasound aufzuschweiissen on the film of the soft packaging. The soft packaging is slightly deformed during handling, especially when it is still full, by gripping and accordingly increases the level of the liquid up into the closure area. If you put a return, as usual, at the lowest point, so this effect would be favored.
Hinzu kommt, dass man um eine sichere und schnelle Verschweissung zu realisieren einen relativ dünnwandigen Flansch und eine dünnwandige Tülle bildet. Um aber ein sicheres Hantieren zu erreichen wäre es wünschenswert, wenn insbesondere die Mantelwand der Tülle dickwandig wäre, um ein Verformen des ganzen Verschlusses während der Handhabung zu vermeiden.In addition, in order to realize a secure and rapid welding, a relatively thin-walled flange and a thin-walled grommet are formed. But to one To achieve safe handling, it would be desirable if in particular the jacket wall of the spout would be thick-walled in order to avoid deformation of the entire closure during handling.
Giesst man direkt aus der Tülle, so läuft immer ein Teil der Flüssigkeit entlang der Tülle nach Aussen ab. Hiermit wird das Gewinde verschmutzt und bei jeder Schraubbewegung wird das Material weiter nach unten transportiert, so dass die gesamte Ästhetik des Verschlusses nicht mehr gegeben ist.If you pour directly out of the spout, some of the liquid will always flow out along the spout. This dirty the thread and with each screwing movement, the material is transported further down, so that the overall aesthetics of the closure is no longer given.
Die vorliegende Erfindung hat sich daher zur Aufgabe gestellt, einen Kunststoffverschluss der eingangs genannten Art so zu verbessern, dass dieser für Weichverpackungen, insbesondere Schlauchbeutel, besonders geeignet ist und die vorgenannten Nachteile behebt.The present invention has therefore set itself the task to improve a plastic closure of the type mentioned above so that it is particularly suitable for soft packaging, especially tubular bag, and overcomes the aforementioned disadvantages.
Einen Kunststoffverschluss dieser Art mit den Merkmalen des Oberbegriffes zeichnet sich dadurch aus, dass der mit dem Behältnis verbindbare Tüllenteil einen zur schweissbaren Verbindung mit einem als Schlauchbeutel gestalteten Behältnis dienenden Flansch aufweist und die Kappenwand mit einem umlaufenden Kragen versehen ist, in dem ein Innengewinde angeordnet ist, wobei die Kappe auf der Tülle des mit einem Behältnis verbindbaren Tüllenteils mittels eines Aussengewindes aufschraubbar ist, wobei auf der Aussenseite der Kappenmantelwand, im Bereich der vom Kragen überdeckt ist, eine umlaufende Dichtwulst als erste Dichtung angeordnet ist und eine verbleibende plane Fläche an einer oberen Kante der Tülle als deformierbare Pressdichtung ausgestaltet ist und eine zweite Dichtung bildet.A plastic closure of this kind with the features of the preamble is characterized in that the sleeve part connectable to the container has a weldable connection to a container designed as a tubular bag serving flange and the cap wall is provided with a circumferential collar in which an internal thread is arranged , wherein the cap on the spout of the connectable with a container Tüllenteils by means of an external thread is screwed, being arranged on the outside of the cap shell wall, in the area covered by the collar, a circumferential sealing bead as the first seal and a remaining flat surface on an upper Edge of the spout is designed as a deformable press seal and forms a second seal.
Dank dieser konzentrischen Ausgestaltungsform mit der ringförmigen Verbindungswand wird eine erhöhte Festigkeit erzielt, auch wenn der gesamte Verschluss dünnwandig realisiert wird, da Ausguss und Tülle eine Versteifung bilden und andererseits im geschlossenen Zustand die als Dosierbecher gestaltete Kappe mit seiner Aussenfläche an der Innenfläche der Tülle anliegt und somit stützend wirkt. Dank der bezüglich der Tülle nach oben versetzten Verbindungswand und der zur ebenfalls nach oben versetzten Verbindungswand ebenso Rückflussöffnung wird zudem vermieden, dass schon bei geringem Druck auf dem Behältnis die Flüssigkeit in den Bereich zwischen der Kappe und dem Ausguss gelangt.Thanks to this concentric design with the annular connecting wall increased strength is achieved, even if the entire closure is realized thin-walled, since the spout and spout form a stiffener and on the other hand in the closed state designed as a dosing cup cap rests with its outer surface on the inner surface of the spout and thus supporting. Thanks to the relation to the spout upwardly offset connecting wall and also upwardly offset connecting wall as well as reflux opening is also avoided that even at low pressure on the container, the liquid enters the area between the cap and the spout.
Weitere vorteilhafte Ausgestaltungsformen des Erfindungsgedankens gehen aus den abhängigen Ansprüchen hervor und deren Bedeutung und Wirkungsweise wird in der nachfolgenden Beschreibung mit Bezug auf die anliegenden Zeichnungen erläutert.Further advantageous embodiments of the inventive concept will become apparent from the dependent claims and their meaning and effect will be explained in the following description with reference to the accompanying drawings.

Der Kunststoffverschluss ist gesamthaft mit 1 bezeichnet. Er besteht aus zwei Teilen, nämlich einen Tüllenteil 2 und einer darauf aufschraubbaren Kappe 3. Dieser gesamte Verschluss im zusammengebauten Zustand ist in der
Der Tüllenteil 2 besteht aus der eigentlichen Tülle 20, die einem zylindrischen Rohrabschnitt entspricht und endständig einen Flansch 23 aufweist. Die Tülle 20 besitzt auf der Aussenseite seiner Mantelwand 22 ein Aussengewinde 21. Bezüglich des unteren Randes der Tülle 20 nach oben versetzt, und damit oberhalb der Ebene in der der Flansch 23 verläuft, ist eine ringförmige Verbindungswand 24 radial nach innen gerichtet von der Innenseite der Mantelwand 22 angeformt. Diese Verbindungswand 24 verbindet die Mantelwand 22 mit einem schnabelförmigen Ausguss 25. Dieser Ausguss ist somit konzentrisch innerhalb der Mantelwand 22 der Tülle 20 angeordnet. Der Ausguss 25 ist durch einen zylindrischen Rohrabschnitt gebildet, der geneigt zur Zentrumsachse Z geschnitten ist. Diese Zentrumsachse ist die gemeinsame Zentrumsachse sowohl für die Tülle 20 als auch für den Ausguss 25. Die erwähnte Verbindungswand 24 verläuft' senkrecht zu dieser Verbindungsachse Z. Der Ausguss 25 ist in der Höhe so bemessen, dass der schnabelförmige Ausguss 25 mit seinem Spitze die Mantelwand 22 der Tülle 20 mindestens um die Breite des Abstandes zwischen der Mantelwand 21 und der Wand des Ausgusses 25 überragt.The
Wie bereits erwähnt ist der schnabelförmige Ausguss 25 aus einem zylinderförmigen Rohrabschnitt gebildet. Er weist somit eine zylindrische Mantelwand 26 auf. Die Spitze 27 des schnabelförmigen Ausgusses 25 liegt auf der längsten Mantellinie. Auf der kürzesten Mantellinie bzw. im Bereich der kürzesten Mantellinie ist der Ausguss 25 mit einer Rückflussöffnung 28 versehen. Diese Rückflussöffnung 28 kann im Prinzip als ein Fenster gestaltet sein, in der hier dargestellten und bevorzugten Ausführungsform ist jedoch diese Rückflussöffnung 28 als eine in senkrechter Richtung sich erstreckende, schlitzförmige Ausnehmung gestaltet. Diese Lösung ist insbesondere bevorzugt, da auf dieser Weise der gesamte Tüllenteil 2 ohne Schieber gefertigt werden kann.As already mentioned, the beak-shaped
Die Kappe 3 ist nachfolgend mit Bezug auf die
Wie bereits eingangs erwähnt dient der erfindungsgemässe Kunststoffverschluss zur Anbringung auf einen Schlauchbeutel. Zur Befestigung dient der Flansch 23 mittels dem der Kunststoffverschluss 1, beispielsweise mit Ultraschall, auf die Kunststofffolie der Schlauchbeutels aufschweissbar ist. Dank der Doppelwandigkeit des Tüllenteiles 2, gebildet aus der Tülle 20 und den konzentrisch dazu angebrachten, schnabelförmigen Ausguss 25 mit der Verbindungswand 24, ergibt sich eine erhöhte Stabilität. Entsprechend braucht diese Stabilität nicht mehr durch den Flansch 23 erhöht zu werden, und folglich kann der Flansch 23 äusserst dünnwandig gebildet werden. Diese Dünnwandigkeit des Flansches 23 erleichtert die Verschweissung und reduziert die Schweisszeit. Die Wandstärke des Flansches 23 wird bevorzugterweise um 20 - 40% dünner gestaltet als die Mantelwand 22 der Tülle 20.As already mentioned, the plastic closure according to the invention is used for attachment to a tubular bag. For attachment, the
Hinzu kommt, dass auch die Kappe 3 stabilisierend wirkt. Dies liegt daran, dass die Kappenmantelwand 30 so dimensioniert ist, dass sie praktisch mit einem minimalen Untermass in die Tülle 20 eingreift.In addition, the
Die Rückflussöffnung 28 ist nicht nur oberhalb der Ebene in der der Flansch 23 verläuft, sondern auch oberhalb jener Ebene in der die ringförmige Verbindungswand 24 verläuft. Dies stellt sicher, dass bei einem vollständig gefüllten Schlauchbeutel, allein schon durch das Fassen desselben, nicht bereits eine gewisse Menge des Schlauchbeutelinhaltes in den trogförmigen Zwischenraum zwischen die Mantelwand 22 der Tülle und den Ausguss 25 gelangt. Trotzdem kann es vorkommen, insbesondere wenn der Benutzer den Schlauchbeutel zu fest quetscht, dass Flüssigkeit in diesen Bereich kommt. Sobald er dies jedoch realisiert und den Druck etwas reduziert wird ein Grossteil der Flüssigkeit durch die Rückflussöffnung 28 zurückströmen. Diese Restmenge, die nun in diesem ringförmigen Trog verbleibt, wird bei einem üblichen Ausgusswinkel in diesem Bereich verbleiben. Erst wenn sich der Schlauchbeutel bereits stark geleert hat und der Ausgusswinkel gegen 90° zur Horizontalen kommt, könnten Reste aus diesem ringförmigen Trog ausströmen. Dann befindet sich aber praktisch auch der Rand der Tülle 20 oberhalb der Öffnung 34 der Kappe bzw. des nun als Dosierbecher dienenden Teiles.The
Im Gegensatz zu rigiden Gefässen, wie beispielsweise Kunststoffflaschen oder Glasflaschen können in Schlauchbeutel erheblich höhere Innendrucke auftreten und entsprechend sind höhere Anforderungen an die Dichtigkeit zu erfüllen. Hierzu wird auf die
Damit dieser Effekt möglichst gross ist, muss selbstverständlich der Durchmesser im Bereich der Dichtwulst 35 grösser sein als der Innendurchmesser der Tülle 20 bzw. der Innendurchmesser der Mantelwand 22. Damit man trotzdem diesen Verschluss mit vernünftigem Kraftaufwand schliessen kann, ist die Mantelwand der Tülle im Bereich des oberen Randes mit einer Anfasung 36 versehen.Of course, in order for this effect to be as large as possible, the diameter in the region of the sealing
Diese Anfasung führt dazu, dass eine Reststirnfläche 37 verbleibt, die relativ dünn ist. Ist nun die Anschlagswulst 29 korrekt angebracht, so lässt sich die Kappe 3 bei der Montage so fest zuschrauben, dass der Kragen 32 endständig auf die Anschlagswulst 29 zum Anliegen kommt und dabei gleichzeitig die Reststirnfläche 37 an der Kragenverbindungswand 38 unter einem genügenden Druck zum Anliegen kommt und sogar dabei leicht deformiert wird. So ergibt sich zwischen der Reststirnfläche 37 und der Kragenverbindungswand 38 eine zweite Dichtung die als Pressdichtung realisiert ist. Schliesslich bildet sich aber auch noch eine dritte Dichtung, ebenfalls als Pressdichtung zwischen dem unteren Rand des Kragens 32 und dem Anschlagwulst 29.This chamfering results in leaving a
Entsprechend ergibt sich so ein Kunststoffverschluss der speziell für Schlauchbeutel geeignet ist unter Meidung der Nachteile des Standes der Technik.Accordingly, this results in a plastic closure which is particularly suitable for tubular bags while avoiding the disadvantages of the prior art.
