Abstract

A guarantee closure having a closure body with a guarantee foil and a pour-out spout as well as a closure cap fitting onto the closure body. The pour-out spout is arranged on the closure body such that it may be pivoted up. The guarantee foil, by pivoting-up the pour-out spout into the pour-out position, is cut open and thus frees the passage to the pour-out spout. The closure body comprises a relief for receiving the guarantee foil and forms above the relief, by two shoulders arranged over one another and distanced from one another, a free space for receiving the lying pour-out spout. This is enclosed and held by a film-hinge material bridge which in the lying condition connects the two shoulders with a surface which seen from the outside is concave and on the upper side of the lying pour-out spout runs together to a point which defines the pivoting axis of the pour-out spout. On pivoting up the pour-out spout the film-hinge material bridge snaps into a permanent shape which is convex when viewed from the outside and thus holds the pour-out spout in the closure position.

Description

Diese Erfindung betrifft einen Garantie-Verschluss für Flüssigkeitsbehälter oder Schüttgutbehälter zur Verpackung etwa von Salz, Zucker und ähnlichen schütt- bzw. rieselfähigen Stoffen. Um einen Garantie-Verschluss handelt es sich dabei deshalb, weil beim erstmaligen Öffnen eine Garantiefolie oder die Verpackungshaut selbst aufgeschnitten werden muss.This invention relates to a guarantee closure for liquid containers or bulk containers for packaging such as salt, sugar and the like pourable or pourable substances. It's about a warranty clasp this is because, when opening for the first time, a guarantee film or the packaging skin itself must be cut open.

Viele Verschlüsse von Lebensmittelbehältern und -Flaschen wie auch Verschlüsse von Behältern für Reinigungsmittel oder allerlei Flüssigkeiten wie Schmieröle, Chemikalien und ähnliches sind als Garantieverschlüsse ausgeführt. Wenn der Verschlussdeckel entfernt wird, so bleibt der Inhalt immer noch hermetisch verschlossen, bis eine meist als Dichtfolie ausgeführte Garantiedichtung gesondert durchstochen oder entfernt wird.Many closures of food containers and bottles as well as closures of containers for detergents or all kinds of liquids such as Lubricating oils, chemicals and the like are designed as guarantee closures. When the cap is removed, the contents are still hermetic closed until a usually executed as a sealing foil warranty seal separately punctured or removed.

Als Beispiel für einen solchen Garantieverschluss mag ein breiten Kreisen bekannter Kunststoffverschluss mit Verschlusskörper und zugehörigem Deckel dienen, wie er für Ketchup-Flaschen verwendet wird. Der Verschlusskörper weist einen nach oben gerichteten Ausguss-Stutzen auf und an seiner Unterseite befindet sich eine Alufolie, die dort eingelegt oder aufgeklebt ist und als Garantiedichtung oder Garantieverschluss wirkt. Wird eine neue Flasche zum ersten Mal geöffnet, so wird in einigen Fällen zunächst ein Garantieband entfernt, wonach der Verschlussdeckel hochgeklappt werden kann. Der Verschlussdeckel ist als Kappe ausgeführt, und wenn diese Kappe zugeklappt ist, umschliesst sie einen Hohlraum auf dem Verschlusskörper. Der Verschlusskörper seinerseits ist auf das Flaschengewinde aufgeschraubt. Auf diesem Verschlusskörper angeordnet ist ein senkrecht auf der Verschlusskörperschulter stehender Ausguss-Stutzen, der mit dem Hochklappen der Verschlusskappe freigegeben wird. Dieser Ausguss-Stutzen ist auf seiner Unterseite von einem Garantieverschluss in Form einer unterhalb des Verschlusskörpers eingelegten Alufolie verschlossen. Bevor man also erstmals Ketchup ausgiessen kann, muss diese Alufolie am unteren Ende des Ausguss-Stutzens durchstochen werden. Herkömmlich wird das mit einem spitzen Gegenstand gemacht, zum Beispiel mit einer Messerspitze. Der Nachteil dabei besteht allerdings darin, dass die Folie nicht sauber längs des inneren Stutzenrandes weggeschnitten wird, sondern mehr oder weniger unregelmässig zerfetzt wird. Einzelne Brauen der Alufolie mögen anschliessend noch in den Ausguss-Stutzen ragen oder gar lösgelöst von der Alufolie beim Ausgiessen mit dem Inhalt nach aussen kommen. Für das erstmalige Öffnen eines derartigen Verschlusses bzw. dessen Garantiefolie muss also ein zusätzliches Werkzeug, etwa ein Messer oder eine Nadel, verwendet werden. Ausserdem erfolgt diese Öffnung der Garantiefolie nicht systematisch und in einer technisch solcherart sauberen Weise, die eine vollständige Freigabe des Strömungsquerschnittes des Ausguss-Stutzens sicherstellen würde.As an example of such a guarantee closure may be a wide circles known plastic closure with closure body and associated cover serve as it is used for ketchup bottles. The closure body has an upwardly directed spout on and located on its underside an aluminum foil, which is inserted or glued there and as a warranty seal or warranty clasp works. If a new bottle is opened for the first time, Thus, in some cases, a guarantee strip is removed, after which the Closing lid can be folded up. The closure lid is as a cap executed, and when this cap is closed, it encloses a cavity on the closure body. The closure body in turn is on the Screwed thread. On this closure body is arranged a perpendicular to the closure body shoulder standing spout, which with the folding up of the cap is released. This spout nozzle is on its underside of a guarantee closure in the form of a below closed the shutter body inserted aluminum foil. So before you go For the first time ketchup can pour out, this aluminum foil at the lower end of the Pouring spout to be pierced. This is usually done with a sharp tip Subject made, for example, with a knife tip. The disadvantage here However, it is that the film is not clean along the inner neck edge is cut away, but more or less irregularly shredded becomes. Individual brewing of the aluminum foil may still be in the spout protrude or even dissolved from the aluminum foil when pouring with the contents come to the outside. For the initial opening of such a closure or its warranty film must therefore an additional tool, such as a knife or a needle. In addition, this opening of the guarantee film takes place not systematically and in a technically clean way that a complete release of the flow cross-section of the spout nozzle would make sure.

Beim Flüssigkeitsbehälter muss es sich aber nicht unbedingt um eine Flasche handeln, sondern es kann auch eine Kartonbox eingesetzt werden, wie das etwa für allerlei Fruchtsäfte, Limonaden, Süsswasser, Tee und Milchprodukte praktiziert wird. Kartonboxen werden überdies auch für die Verpackung von Schüttgütern wie Zucker, Salz und Ähnlichem eingesetzt. Bei diesen Kartonboxen stellt sich stets das Problem, wie der Karton an der Stelle, wo der Verschluss sitzt, geöffnet wird. Bei diesen Kartonboxen ist es nämlich der Karton selbst, welcher die Rolle der Garantiefolie übernimmt, und der Karton muss deshalb nach dem oder mit dem Öffnen des Verschlusses durchstochen oder aufgeschnitten werden, was bisher durch einen gesonderten Arbeitsschritt erfolgen musste und oftmals nur unter Zuhilfenahme von Werkzeugen zu bewerkstelligen war. Aus der FR-2'789'659 A ist ein Verschluss mit einem um 90° schwenkbaren Ausguss-Stutzen bekanntgeworden. Der untere Teil des Ausguss-Stutzens reisst beim Aufschwenken eine Dichtfolie auf. Der nach unten schwenkbare Teil weist einen Querschnitt auf, welcher der Hälfte des oberen Teils des Ausguss-Stutzens entspricht, bildet also einen Halbzylinder. Entsprechend ist dieser aussen rund und bildet keine Schneide. Der endseitige Rand dieses Halbzylinders trägt eine Anzahl von Reisszähnen. Desweiteren ist dieser Halbzylinder gegenüber dem oberen, rohrförmigen Ausguss-Stutzen geschwächt und droht beim Abschwenken, wenn zum Aufreissen ein grosses Drehmoment nötig ist, zu knicken. Die US 6'161'728 A zeigt einen weiteren Verschluss mit einem um 90° schwenkbaren Ausguss-Stutzen, bei dessen Aufschwenken zwei gesonderte, seitlich zum Ausguss-Stutzen versetzte, am Stutzenflansch befestigte Messer abgeschwenkt werden. Diese Lösung ist jedoch aufwändig und teuer.The liquid container is not necessarily a bottle But it can also be used a cardboard box, like the for all sorts of fruit juices, sodas, fresh water, tea and dairy products is practiced. Carton boxes are also used for packaging Bulk materials such as sugar, salt and the like used. With these carton boxes always poses the problem of how the carton sits where the closure sits is opened. In these carton boxes, it is the carton itself which the role of the guarantee foil takes over, and the cardboard must therefore after the or pierced or cut open with the opening of the closure, what had previously been done by a separate step and often only with the help of tools was to accomplish. From FR-2'789'659 A is a closure with a 90 ° swiveling spout known. The lower part of the spout tears at the Swing open a sealing foil. The swiveling down part has a Cross-section on which half of the upper part of the spout-neck corresponds, thus forms a half-cylinder. Accordingly, this is outside around and does not form a cutting edge. The end edge of this half-cylinder carries one Number of teeth. Furthermore, this half cylinder is opposite to the weakened upper, tubular spout and threatens when pivoting, if a large torque is needed to tear open. The US 6'161'728 A shows another closure with a 90 ° swiveling Pouring spout, in the swinging two separate, laterally to Swiveled spout spigot, knife attached to spigot flange become. However, this solution is complicated and expensive.

Es ist daher die Aufgabe der vorliegenden Erfindung, einen Garantie-Verschluss für Flüssigkeits- und Schüttgutbehälter zu schaffen, welcher die obengenannten Nachteile überwindet und bei dem mit dem erstmaligen Öffnen des Verschlusses die Garantiefolie sauber geöffnet wird und dabei sichergestellt wird, dass der Querschnitt des Ausguss-Stutzens freigegeben wird und auch freigehalten bleibt.It is therefore the object of the present invention to provide a guarantee closure for liquid and bulk containers to create, which the above Overcomes disadvantages and when opening the shutter for the first time the guarantee film is opened clean and it is ensured that the cross section of the spout is released and also kept free remains.

Diese Aufgabe wird gelöst von einem Garantie-Verschluss für einen Flüssigkeits- und Schüttgutbehälter, bestehend aus einem Verschlusskörper mit einem darin in Ausgangslage liegend angeordneten, jedoch aus dieser Position aufschwenkbaren Ausguss-Stutzen, der gegenüber dem Verschlusskörper dichtend von einer filmscharnierartigen Materialbrücke umschlossen ist, welche beim Aufschwenken des Ausguss-Stutzens von einer konkaven in eine konvexe Form springt und umgekehrt und dadurch den Ausguss-Stutzen in den Endpositionen seines Schwenkbereichs festhält, sowie einer zugehörigen Garantiefolie, die in liegender Position des Ausguss-Stutzens unterhalb und längs desselben verläuft, wobei die Schwenkachse am Ausguss-Stutzen an einer solchen Stelle liegt, dass sein hinterer Abschnitt beim Aufschwenken des Ausguss-Stutzens nach unten schwenkt, und der sich dadurch auszeichnet, dass der Ausguss-Stutzen in seiner liegenden Position mit seinem unteren, hinteren Ende so in eine Spitze ausläuft, dass von seiner Wandung zwei Kanten gebildet werden, welche schiefwinklig zur Ausguss-Stutzenachse auf diese Spitze zulaufen, und dass die Spitze in eine Perforierspitze ausgeformt ist, indem sie einen zur Garantiefolie zeigenden Kunststoff-Kegel bildet oder ein längs der Ausguss-Stutzenachse ausgerichtetes, flächiges Kunststoff-Dreieck mit nach unten gerichteter scharfer Spitze, weiter dass der Ausguss-Stutzen in dieser liegenden Position auf seiner unteren hinteren Längsseite eine scharfe, kielförmige Längskante bildet, sodass beim Aufschwenken des Ausguss-Stutzens die Garantiefolie zunächst von der Perforierspitze durchstechbar ist und hemach von der Längskante ab der Perforationsstelle aufschneidbar ist.This task is solved by a guarantee closure for one Liquid and bulk container, consisting of a closure body with one arranged in it in the starting position, but from this position Swiveling spout, which faces the closure body is sealingly enclosed by a film hinge-like material bridge, which when swinging the spout neck from a concave into a convex Form jumps and vice versa and thereby the spout nozzle in the Holds end positions of its pivoting range, as well as an associated Warranty film, lying in the lying position of the spout below and along the same runs, wherein the pivot axis at the spout on a nozzle such place is that its rear section when swinging the Pouring spout pivots down, and which is characterized in that the spout nozzle in its lying position with its lower, rear End so ends in a point that formed by its wall two edges which are at an angle to the spout nozzle axis on this tip run, and that the tip is formed into a perforating point by forms a guarantee film showing plastic cone or a along the Spout spigot aligned, flat plastic triangle with pointed sharp tip down, further that the spout-neck in this lying on its lower rear long side a sharp, Keel-shaped longitudinal edge forms, so when swinging the spout-neck the guarantee film is first pierceable by the perforating tip and hemach can be cut from the longitudinal edge from the perforation point.

Vorteilhafte Ausführungen dieses Garantie-Verschlusses sind in den Zeichnungen in verschiedenen Positionen dargestellt und werden in der nachfolgenden Beschreibung im einzelnen erläutert. Anhand dieser Zeichnungen wird auch die Funktion des Verschlusses erklärt.Advantageous versions of this warranty closure are in the Drawings are presented in different positions and are discussed in the following Description explained in detail.

Die Figur 1 zeigt den Garantie-Verschluss in einem Längsschnitt längs der Achse der Flasche 20, die hier allerdings nur angedeutet ist. Er besteht aus einem Verschlusskörper 1, einem Ausguss-Stutzen 2 und einer zum Verschlusskörper 1 passenden Verschlusskappe 3. Diese Verschlusskappe 3 ist hier mittels eines Filmschamiers 18 einstückig mit dem Verschlusskörper 1 verbunden, sodass sie an ihm aufklappbar ist. Es ist aber auch denkbar, die Verschlusskappe 3 als gesondertes Stück zu fertigen, wobei sie dann entweder mit Schappverschlüssen ausgerüstet ist, sodass sie auf den Verschlusskörper 1 aufsteckbar ist, oder aber dass sie mit einem Innengewinde ausgerüstet ist und somit auf ein passendes Aussengewinde am Verschlusskörper 1 aufschraubbar ist. Der Verschlusskörper 1 bildet auf seiner Unterseite einen rundum verlaufenden Absatz 11, auf den eine Garantiefolie 4 eingelegt oder aufgeklebt ist. Diese Garantiefolie 4 stellt sicher, das der Verschluss den Behälter oder die Flasche 20 hermetisch verschliesst und garantiert gleichzeitig, dass derjenige, der den Verschluss das erste Mal öffnet, auch tatsächlich der Erste ist, welcher Flüssigkeit aus dem Behälter oder der Flasche 20 entnehmen kann. Im hier gezeigten Beispiel ist der Verschlusskörper 1 mittels eines Innengewindes 15 auf das Aussengewinde 16 am Flaschenhals 17 dieser Flasche 20 aufgeschraubt. Das Besondere an diesem Garantie-Verschluss ist es nun, dass der Ausguss-Stutzen 2 am Verschlusskörper 1 aufschwenkbar angeordnet ist, wobei die Garantiefolie 4 durch Aufschwenken des Ausguss-Stutzens 2 in dessen Ausgiesslage durch diesen selbst automatisch aufgeschnitten wird. Hierzu ist der Ausguss-Stutzen 2 wie hier gut sichtbar liegend zwischen zwei am Verschlusskörper 1 gebildeten, in Abstand voneinander übereinander angeordneten Schultern 12,13 gehalten. Genauer gesagt wird er von einer filmscharnierartigen Materialbrücke 5 gehalten, welche den ganzen Ausguss-Stutzen 2 dichtend umschliesst und die beiden Schultern 12,13 am Verschlusskörper 1 verbindet. In der Figur 1, die ja den Garantie-Verschluss vor seinem ersten Öffnen zeigt, ist der Ausguss-Stutzen 2 liegend im Freiraum 14 untergebracht, welcher von den beiden Schultern 12,13 des Verschlusskörpers 1 unten und oben begrenzt wird, sowie seitlich durch seine senkrecht zu den Schultern stehende Wandung. In dieser Position des Ausguss-Stutzens 2 bildet die filmscharnierartige Materialbrücke 5 von aussen her gesehen, das heisst hier von links gesehen, eine konkave Fläche. Oberhalb des Ausguss-Stutzens 2, wo die den Ausguss-Stutzen 2 umschliessende Materialbrücke 5 zusammenläuft, bildet der Punkt 6 eine Drehachse 6 für den Ausguss-Stutzen 2. Wie man sieht, ist der Ausguss-Stutzen 2 auf seiner hier unteren Seite 7 gegen rechts hin, also gegen dasjenige Ende hin, das gegen den Behälter 20 hin geschwenkt werden soll, länger als auf der oberen Seite 8 und läuft dort in eine Spitze 9 aus. Damit sind von seiner Wandung zwei Kanten 10 gebildet, welche schiefwinklig auf diese Spitze 9 zulaufen. Diese Aussenkanten 10 wirken als Schneidkanten, wie das später klar wird.FIG. 1 shows the guarantee closure in a longitudinal section along the Axis of the bottle 20, which is only hinted at here. It consists of one Closure body 1, a pour spout 2 and one to the closure body. 1 matching cap 3. This cap 3 is here by means of a Filmschamiers 18 integrally connected to the closure body 1, so they it is hinged on it. But it is also conceivable, the cap 3 as a separate Piece to manufacture, in which case they are either with snap closures is equipped so that it can be plugged onto the closure body 1, or that it is equipped with an internal thread and thus to a suitable External thread on the closure body 1 can be screwed. The closure body 1 forms on its underside an all-round paragraph 11, on the one Guarantee foil 4 is inserted or glued on. This warranty film 4 ensures the closure hermetically seals the container or bottle 20 and at the same time guarantees that the one who opens the lock for the first time, actually, the first thing is which liquid from the container or bottle 20 can take. In the example shown here, the closure body 1 by means of an internal thread 15 on the external thread 16 at the bottleneck 17th screwed on this bottle 20. The special feature of this guarantee closure it is now that the spout nozzle 2 on the closure body 1 swung open is arranged, the guarantee film 4 by pivoting the spout neck 2 cut automatically in the pouring through this itself becomes. For this purpose, the spout is 2 as seen here clearly lying between two formed on the closure body 1, arranged one above the other at a distance from each other Shoulders 12,13 held. More precisely, he is of a film hinge type Material bridge 5 held, which the entire spout 2 encloses sealing and connects the two shoulders 12,13 on the closure body 1. In the figure 1, yes the guarantee closure before its first opening shows, the spout nozzle 2 is accommodated lying in the free space 14, which bounded by the two shoulders 12,13 of the closure body 1 below and above is, as well as laterally by its perpendicular to the shoulders wall. In this position of the spout neck 2 forms the film hinge-like Material bridge 5 seen from the outside, that is seen here from the left, a concave surface. Above the spout-neck 2, where the spout-spigot 2 enclosing material bridge 5 converges, the point 6 forms an axis of rotation 6 for the spout 2. As you can see, the spout 2 is on his lower side 7 towards the right, that is towards the end, the is to be pivoted against the container 20, longer than on the upper Page 8 and runs out there in a tip 9. So are two of its wall Edges 10 are formed, which run at an angle to this tip 9. These outer edges 10 act as cutting edges, as will become clear later.

Unterhalb der Figur 1 ist der Garantie-Verschluss anhand von Figur 2 in einer Ansicht von vorne gezeigt, wobei man ihn hier von der linken Seite der Figur 1 her sieht. Die Verschlusskappe 3 weist eine sich nach unten erstreckende, den Verschlusskörper 1 an dieser Stelle überlappende Zunge 19 auf. Diese Zunge 19 ist vorteilhaft über eine Dünnstelle 21 vom übrigen Material der Verschlusskappe 3 etwas abgesetzt, sodass sie leicht etwas nach aussen geschwenkt und mit zwei Fingern ergriffen werden kann. Zum Öffnen des Verschlusses ergreift man diese Zunge 19 an der Verschlusskappe 3 und schwenkt die Verschlusskappe 3 auf dem darunterliegenden Verschlusskörper 1 um ihre auf der Rückseite angeordnete Schamierverbindung 18 hoch.Below the figure 1 is the guarantee closure with reference to Figure 2 in a view from the front, where you can see him from the left side of the figure 1 looks forth. The cap 3 has a downwardly extending, the Closure body 1 at this point overlapping tongue 19. This tongue 19 is advantageous over a thin spot 21 from the rest of the material of the cap 3 slightly offset so that they are slightly slightly outwards and with two Fingers can be taken. To open the shutter you take this Tongue 19 on the cap 3 and pivots the cap 3 the underlying closure body 1 to their arranged on the back Sham marriage 18 high.

Die Figur 3 zeigt den Garantie-Verschluss in einem Längsschnitt mit bereits in dieser Weise aufgeklappter Verschlusskappe 3. Anhand dieser Figur soll nun das Aufschwenken des Ausguss-Stutzens 2 und das dabei erfolgende Aufschneiden der Garantiefolie 4 erklärt werden. Man ergreift nämlich mit zwei Fingern den Vorderteil des Ausguss-Stutzens 2, der aus der Materialbrücke 5 hervorragt, und schwenkt diesen um die Drehachse 6 hoch in Richtung des eingezeichneten Pfeiles. Der Ausguss-Stutzen 2 kann auch mittels Aufdrücken der Daumenbeere auf dessen Mündung und hernach einer Schwenkbwegung des Daumens aus seiner liegenden Lage um die Drehachse 6 herum hochgeschwenkt werden. Wie das hier eingezeichnet wird, reisst dabei zunächst die Spitze 9 des unteren Endes des Ausguss-Stutzens 2 ein Loch in die Garantiefolie 4, und bei weiterem Aufschwenken des Ausguss-Stutzens 2 schneiden die Kanten 10 beidseits des entstandenen Loches weiter, sodass aus der Garantiefolie 4 ein Streifen ausgeschnitten wird, der vom weiterschwenkenden Ausguss-Stutzen 2 zurückgebogen wird. Die Figur 3 zeigt diese Aufschwenkbewegung, während welcher das Zerschneiden der Garantiefolie 4 erfolgt, auf halbem Weg.FIG. 3 shows the guarantee closure in a longitudinal section with already in this way unfolded cap 3. Based on this figure is intended now the pivoting of the spout 2 and the thereby taking place cutting warranty film 4 will be explained. It takes two fingers the front part of the pour spout 2, which protrudes from the material bridge 5, and pivots it about the axis of rotation 6 high in the direction of the drawn Arrow. The spout 2 can also by pressing the Thick berry on its mouth and after a Schwenkbwegung of Thumb pivoted from its lying position about the axis of rotation 6 around become. As this is drawn here, the top 9 of the bottom of the spout 2 a hole in the warranty film 4, and at further swiveling the spout-neck 2 cut the edges 10 on both sides of the resulting hole on, so from the guarantee film 4 a strip is cut, which is bent back from the further pivoting spout 2 becomes. 3 shows this Aufschwenkbewegung, during which the Slicing the guarantee film 4 takes place, halfway.

Die Figur 4 zeigt die Vollendung dieser Bewegung. Jetzt ist der Ausguss-Stutzen 2 in seiner Ausgiesslage angelangt und die Garantiefolie 4 ist hinreichend aufgeschnitten, sodass sie den Querschnitt des Stutzens 2 freigibt und das auch so bleibt, weil der aufgeschnittene Streifen der Garantiefolie 4 vom unteren Ende des Ausguss-Stutzens 2 zurückgehalten wird. Während des Aufschwenkens des Ausguss-Stutzens 2 hat sich die filmscharnierartige Materialbrücke 5 verformt. Sie musste dabei einen Totpunkt überwinden. Bei Überwindung dieses Totpunktes schnappte die Materialbrücke 5 von einer von aussen gesehen zunächst konkaven Form, unter welcher sie eine Federspannung entwickelte, welche den Ausguss-Stutzen 2 in der liegenden Lage hielt, in eine nun konvexe Form, unter welcher sie eine Federspannung in Richtung des Aufschwenkens des Stutzens 2 entwickelt, und ihn deshalb in der einmal eingenommenen Ausgiesslage hält. Der Garantie-Verschluss ist jetzt geöffnet und die Flasche 20 zum Ausgiessen ihres Inhaltes bereit.Figure 4 shows the completion of this movement. Now is the spout 2 arrived in its pouring position and the guarantee film 4 is sufficient cut open so that it releases the cross section of the nozzle 2 and that too so remains because the cut strip of the guarantee film 4 from the lower end the spout 2 is retained. During the swinging of the Spout nozzle 2, the film hinge-like material bridge 5 has deformed. she had to overcome a dead center. In overcoming this dead center the material bridge 5 snapped from a concave view from the outside Form under which she developed a spring tension, which the spout nozzle 2 held in the lying position, in a now convex shape, under which they spring tension in the direction of pivoting of the nozzle. 2 developed, and therefore keeps him in the once taken pouring position. Of the Warranty lock is now open and bottle 20 is pouring out its Content ready.

In Figur 5 ist diese Lage des Garantie-Verschluss mit aufgeklappter Verschlusskappe 3 und mit dem Ausguss-Stutzen 2 in Ausgiesslage und aufgeschnittener Garantiefolie von oben gesehen dargestellt. Wie man hier erkennt, ist am Verschlusskörper 1 auf dessen Vorderseite eine Einbuchtung 29 ausgenommen, welche es erleichtert, bei geschlossener Verschlusskappe 3 die ihn überlappende Zunge 19 zu ergreifen. Das von oben gesehen den Ausguss-Stutzen 2 umgebende Material 5 gehört zur filmscharnierartigen Materialbrücke 5, die hier also konvex nach aussen gekrümmt ist und aufgrund ihrer Federspannung den Stutzen 2 fortan in der Ausgiesstage hält. Die obere Schulter 13 des Verschlusskörpers 1 bildet eine Ausnehmung 23, innerhalb welcher diese Materialbrücke 5 den Ausguss-Stutzen 2 dicht umschliesst, sodass also das Flascheninnere ausschliesslich durch den Ausguss 2 mit dem Flaschenäusseren kommuniziert. Mit unterbrochener Linie ist der Innendurchmesser des Verschlusskörpers 1 eingezeichnet, über den sich die Garantiefolie erstreckt. Diese ist jedoch im hier gezeigten Zustand bereits aufgeschnitten und zur Seite geschoben, wenn auch hier nicht sichtbar. Auf der Innenseite der Verschlusskappe 3 sieht man einen Kragen 22. Dieser ist dazu bestimmt, bei wieder geschlossenem Zustand des Verschlusses den Mündungsrand des Ausguss-Stutzens 2 zu umschliessen, sodass dieser erstens dicht verschlossen wird und zweitens die Lage des Ausguss-Stutzens 2 zusätzlich gesichert wird. In Figure 5, this position of the warranty closure with unfolded cap 3 and with the spout nozzle 2 in pouring and cut open Warranty film shown from above. As you can see here is on the front of the closure body 1, a recess 29 is excluded, which makes it easier, when the cap 3 is closed, the overlapping him To seize tongue 19. Seen from above the spout 2 surrounding material 5 belongs to the film hinge-like material bridge 5, here thus convexly curved outward and due to their spring tension the Stutzen 2 keeps in the Ausgiesstage from now on. The upper shoulder 13 of the closure body 1 forms a recess 23 within which this material bridge 5 the spout neck 2 tightly encloses, so so the inside of the bottle exclusively through the spout 2 communicates with the Flaschenäusseren. With broken line, the inner diameter of the closure body 1 is drawn, over which the warranty film extends. However, this one is shown here Condition already cut open and pushed aside, though here not visible. On the inside of the cap 3 you can see a collar 22. This is intended when the closed state of the closure To enclose the mouth edge of the spout neck 2, so this firstly tightly closed and secondly the position of the spout 2 additionally secured.

Die Figur 6 zeigt schliesslich diesen Garantie-Verschluss in einem Längsschnitt mit wieder zugeklappter Verschlusskappe 3, mit nach erstmaligem Gebrauch in Ausgiesslage stehengebliebenem Ausguss-Stutzen 2. Hier sieht man sehr schön, wie der Kragen 22 an der Verschlusskappe 3 den Mündungsrand des Ausguss-Stutzens 2 umschliesst. Die filmschamierartige Materialbrücke 5 verbleibt in ihrer von aussen gesehen konvexen Form, und das untere Ende des Ausguss-Stutzens 2 drückt die aufgeschnittene Garantiefolie 4 weiterhin zur Seite und hält somit den Ausguss frei.Finally, FIG. 6 shows this guarantee closure in a longitudinal section with again closed cap 3, with after the first time Use in pouring spout remaining spout 2. Here you can see very nice, as the collar 22 on the cap 3 the mouth edge of the Spout spout 2 encloses. The film-like material bridge 5 remains in its outwardly convex shape, and the lower end of the Pour spout 2 pushes the cut warranty film 4 continues to the side and thus keeps the spout free.

In Figur 7 ist der Garantieverschluss in einer Anwendung an einer Karton-Flüssigkeitsbox oder Karton-Schüttgutbox 20' gezeigt, und zwar in der Abbildung links für ein Ausgiessen des Inhaltes über eine Schmalseite der Verpackungsbox, und in der Abbildung rechts daneben für ein Ausgiessen des Inhaltes über eine Ecke der Verpackungsbox. Solche Karton-Packungen werden für allerlei Fruchtsäfte, Limonaden, Süsswasser, Tee und Milchprodukte eingesetzt, in vielen Länder sogar für Weine. Desweiteren werden auch schüttfähige Inhalte wie etwa Zucker und Salz und ähnliche Waren in solchen Kartonboxen verpackt. Anstatt einer kreisrunden Form wie in den Figuren 1 bis 6 gezeigt weist der hier gezeigte Garantieverschluss im Beispiel links eine rechteckige Grundform auf und in der Variante zum Verbauen in der Ecke einer Kartonbox eine schiffchenförmige Grundform. Das Anordnen des Verschlusses in der Ecke ist deshalb von Vorteil, weil dann der Inhalt, der ja am besten in einer Ecke zusammenläuft, restlos aus der Box entleert werden kann. Weitere Grundformen des Verschlusses sind denkbar, je nach den Gegebenheiten und der Gestaltung der Verpackung. Der Garantie-Verschluss 1' kann auf die Kartonbox 20' aufgeklebt sein oder mittels einer Ultraschall-Schweissung dichtend mit der Kartonbox 20' verbunden sein. In diesem Fall ist eine Kunststoff-Folie unterhalb der oberen Abschlussfläche der Kartonbox eingelegt und der Verschluss ist sodann unter Einschluss der Karton-Abschlussfläche mit der darunter eingelegten Kunststoff-Folie wenigstens stellenweise mittels einer Ultraschall-Schweissung verschweisst. In Figure 7, the guarantee closure is in an application on a cardboard liquid box or carton bulk box 20 'shown in the figure left for pouring the contents over a narrow side of the packaging box, and in the picture to the right for pouring the contents over one Corner of the packaging box. Such carton packs are used for all kinds of fruit juices, Sodas, freshwater, tea and dairy products used in many countries even for wines. Furthermore, also pourable content such as Sugar and salt and similar goods packed in such cardboard boxes. Instead of a circular shape as shown in Figures 1 to 6, the one shown here Guarantee closure in the example on the left a rectangular basic form on and in the Variant for installation in the corner of a cardboard box a ship-shaped Basic form. Arranging the closure in the corner is therefore advantageous because then the content, which is best in a corner converges completely the box can be emptied. Other basic forms of the closure are conceivable depending on the circumstances and the design of the packaging. The warranty lock 1 'may be glued to the cardboard box 20' or by means of a Ultrasonic welding seal to be connected to the carton box 20 '. In this Case is a plastic film below the upper end surface of the cardboard box is inserted and the closure is then including the cardboard end surface at least in places with the plastic foil inserted underneath welded by means of ultrasonic welding.

Wie man aus der Figur 8 ersieht, ist die Verschlusskappe 3' hier als flacher Deckel ausgebildet und überlappt den Verschlusskörper 1' nach vorne, das heisst in der Zeichnung nach links, während das Verschlusskappenscharnier 25 etwa in der Mitte der Verschlusslänge angeordnet ist. Der vordere Teil des Deckels ist daher um die Schamierachse 25 nach oben aufschwenkbar, wie das mit einem Pfeil eingezeichnet ist, wozu die Verschlusskappe 3' an ihrem vorderen, auskragenden Rand 24 ergriffen werden kann. Am einfachsten setzt man den Daumen unter dem Rand 24 der Verschlusskappe 3' an, wie das im Bild gezeigt ist, und zieht sie dann hoch. Wie man in der Zeichnung weiter erkennt, ist auf der Unterseite der nach oben schwenkbaren Verschlusskappe 3' ein Ausguss-Stutzen 2' angeformt. Dieser ist auf seiner hinteren bzw. in aufgeschwenktem Zustand unteren Seite abgeschrägt und läuft also gegen dasjenige Ende hin, das beim Aufschwenken gegen den Behälter 20' hin geschwenkt wird, in eine Spitze 9' aus. Damit sind von seiner Wandung zwei Kanten 10' gebildet, welche schiefwinklig auf diese Spitze 9' zulaufen. Nach unten zeigend kann wie hier gezeigt an der Spitze 9' eine Perforierspitze 27 ausgeformt sein. Diese kann von einem mit der Spitze nach unten zeigenden Kunststoff-Kegel gebildet sein, wobei die Spitze des Kegels in eine spitze kurze Nadel auslaufen kann, oder die Perforierspitze wird von einem längs der Ausguss-Stutzenachse ausgerichteten flächigen Kunststoff-Dreieck mit scharfer Spitze gebildet. Die untere hintere Längsseite 7' des Ausguss-Stutzens 2' ist in eine scharfe kielförmige Längskante ausgeformt, welche als Schneidkante wirken kann, wie das noch erklärt wird. Unter dem Verschluss verläuft der Karton 28 der Flüssigkeits- oder Schüttgutbox und wird von der Spitze 27 leicht nach unten gedrückt. Der Verschluss ist von oben auf die Kartonbox aufgeleimt oder mittels einer Ultraschall-Schweissung mit einer unterhalb des Kartons eingelegten Kunststoff-Folie 26 verbunden.As can be seen from Figure 8, the cap 3 'is here as flat Cover formed and overlaps the closure body 1 'forward, that is in the drawing to the left, while the cap hinge 25 is approximately in the center of the shutter length is arranged. The front part of the lid is therefore swinging up to the hinge axis 25 upwards, like that with a Arrow is shown, including the cap 3 'at its front, cantilevered Edge 24 can be taken. The easiest way is to put your thumb under the edge 24 of the cap 3 ', as shown in the picture, and then pull her up. As you can see in the drawing is on the bottom the upwardly pivotable cap 3 'a spout 2' formed. This is lower on its rear or in the swung-open state Beveled side and so runs towards the end, the swinging pivoted against the container 20 ', in a tip 9' from. Thus, two edges 10 'are formed by its wall, which obliquely to run to this point 9 '. Pointing downwards as shown here on the Tip 9 'a perforating 27 be formed. This can be from one with the Tip be formed downwardly facing plastic cone, the tip of the Cone may leak into a pointed short needle, or the perforating tip will from a flat plastic triangle aligned along the spout nozzle axis formed with sharp point. The lower rear longitudinal side 7 'of the spout 2 'is formed in a sharp keel-shaped longitudinal edge, which can act as a cutting edge, as will be explained. Under the lock the carton 28 of the liquid or bulk material box runs and gets off the top 27 pressed down slightly. The closure is glued on top of the cardboard box or by means of ultrasonic welding with one below the carton inserted plastic film 26 connected.

Die Figur 9 zeigt, wie der Verschluss funktioniert. Zunächst wird mit einem Finger, am besten mit dem Daumen, der Verschlussdeckel 3' an seinem Rand 24 ergriffen und um die Schamierachse 25 hochgeklappt, wodurch gleichzeitig der an der Unterseite des Verschlussdeckels 3' angeordnete Ausguss-Stutzen 2' um 90° in die vertikale Lage geschwenkt wird. Aussen zwischen dem schwenkbaren Ausguss-Stutzen 2' und dem Verschlussgehäuse 1' befindet sich eine dünne Dichtmembrane 5' in Form einer filmscharnierartigen Materialbrücke, die in der Ausgangslage bei liegendem Ausguss-Stutzen 2' wie in Figur 8 gezeigt von aussen gesehen, das heisst in der Zeichnung von links gesehen, konkav gekrümmt ist. Beim Hochschwenken der Verschlusskappe 3' und des daran angeformten Ausguss-Stutzens 2' springt diese Membrane 5' in eine konvexe Form und entwickelt in dieser Lage eine Kraft in Richtung des Hochschwenkens des Ausguss-Stutzens 2'. Weil die Schwenkachse etwa in der Mitte der Länge des Ausguss-Stutzens 2' angeordnet ist, klappt bei seinem Hochschwenken sein hinterer, speziell geformter Teil nach unten. Dabei drückt die Perforierspitze 27 auf den Karton 28 der Flüssigkeitsbox 20' und reisst dort ein Loch in denselben. Das ist ganz wesentlich, denn nur ausgehend von einer solchen Einriss-Stelle lässt sich der dicke Karton 28 weiter aufschneiden. Beim Hochklappen des Ausguss-Stutzens 2' drückt jetzt die untere kielförmige Längskante des Ausguss-Stutzens 2' auf die Einriss-Stelle und diese als Messer wirkende untere Kante am Stutzen 2' schneidet das aufgerissene Loch weiter auf, sodass der untere Teil des Ausguss-Stutzens 2' schliesslich in das Innere der Kartonbox 20' ragt und diese geöffnet ist. In der Figur 9 ist zum besseren Verständnis eine mittlere Schwenkposition von Verschlussdeckel 3' und Ausguss-Stutzen 2' strichliniert eingezeichnet. Schliesslich erreicht der Ausguss-Stutzen 2' die vertikale Lage, in welcher die Dichtmembrane 5' von aussen gesehen konvex gekrümmt ist und den Ausguss-Stutzen 2' in dieser Lage festhält. Wird der Ausguss-Stutzen 2' nach dem Ausgiessen der gewünschten Flüssigkeitsmenge wieder niedergeschwenkt, so springt die Membrane 5' wieder in ihre konkave Form und hält den Stutzen 2' in der liegenden Lage fest. Damit ein flüssiger Inhalt sauber ausgiessbar ist, kann der Rand des Ausgiess-Stutzens 2' mit einer Abtropfnase 30 ausgerüstet sein.Figure 9 shows how the closure works. First, with a Finger, preferably with the thumb, the cap 3 'at its edge 24 taken and folded up to the hinge axis 25, which at the same time at the bottom of the closure lid 3 'arranged spout 2' by 90 ° is pivoted to the vertical position. Outside between the swiveling spout 2 'and the closure housing 1' is a thin sealing membrane 5 'in the form of a film hinge-like material bridge, which in the starting position with horizontal spout 2 'as shown in Figure 8 from the outside seen, that is seen in the drawing from the left, is concavely curved. When swinging up the cap 3 'and the spout formed thereon 2 'jumps this membrane 5' in a convex shape and developed in this position, a force in the direction of the high pivoting of the spout nozzle 2 '. Because the pivot axis approximately in the middle of the length of the spout neck 2 ' is arranged, folds his back up, specially shaped Part down. The perforating tip 27 presses on the cardboard 28 of the Fluid box 20 'and tears a hole in it. That's very important because only from such a tear point can the thick cardboard 28 further cut. When folding up the spout 2 'press now the lower keel-shaped longitudinal edge of the spout neck 2 'on the tear point and this acting as a knife lower edge on the neck 2 'cuts the torn Hole further on, so that the lower part of the spout 2 'finally into the interior of the cardboard box 20 'protrudes and this is open. In the figure 9 is for a better understanding, a mean pivoting position of closure lid 3 ' and spout 2 'dashed lines drawn. Finally, the spout reaches 2 ', the vertical position in which the sealing membrane 5' from the outside Seen convexly curved and the spout nozzle 2 'holds in this position. If the spout nozzle 2 'after pouring the desired amount of liquid pivoted down again, the membrane jumps 5 'back into their concave shape and holds the nozzle 2 'in the lying position. So a liquid Content is pourable, the edge of the spout can 2 'with a drip nose 30 be equipped.
