Abstract

The spout closure comprises a spout (15) with a corresponding spout cap (1). The free opening of the spout is sealed in one piece (5) by a sealing plate and a cutting ring (8) is formed on the underside of the spout cap (1) which fits in the free opening of the spout. Cooperating guide means (4,9) are provided on the outer side of the spout and the inner side of the top. On rotation of the spout cap (1) in the opening direction the above causes the spout cap (1) to be firstly pressed against the spout (15) with a part of the cutting ring (8) thereof which breaks off the sealing plate (5) that is then removed from the spout. The sealing plate (5) further comprises a concentric annular wall (6) on the upper side thereof in the spout (15) and, on the inner side of the lid of the spout cap (1), a clip ring (7) is formed concentrically, which on fitting the cap (1) encloses the annular wall (6) on the sealing plate (5) and generates therewith a clip connection. On lifting off the cap (1) after the initial opening the broken off sealing plate (5) is retained on the cap (1).

Description

Flüssigkeitsverpackungen aus Karton, Getränkedosen und Becher mit Verschluss-Systemen leiden bis heute am Nachteil, dass die gewünschte absolute Gasdichtigkeit nicht gegeben ist, obwohl das eigentliche Packungsmaterial völlig gasdicht ist. Die Problemstelle liegt bei den Verschluss-Systemen. Eine gewisse Gaspermeation und somit ein langsames Eindiffundieren von Sauerstoff durch das Verschlusssystem und dessen Material wird nämlich nicht wirksam vermieden. Die Haltbarkeit der verpackten Flüssigkeiten wie etwa von Milch und Fruchtsäften ist deshalb begrenzt. Obwohl die eigentlichen Packungsmaterialien völlig gasdicht sind und man von einer aspetischen Verpackung spricht, können die Inhaltsstoffe wegen der Diffusion von Sauerstoff durch das Ausgiess- und Verschluss-System "kippen" und verderben.Liquid packaging made of cardboard, beverage cans and cups with closure systems suffer to the present disadvantage that the desired absolute gas-tightness is not given, although the actual packing material is completely gas-tight. The problem lies in the closure systems. A certain gas permeation and thus a slow diffusion of oxygen through the closure system and its material is not effectively avoided. The shelf life of packaged liquids such as milk and fruit juices is therefore limited. Although the actual packing materials are completely gas-tight and one speaks of an aspetic packaging, the ingredients can "tip over" and spoil because of the diffusion of oxygen through the pouring and sealing system.

Ein Lösungsansatz besteht darin, dass die Verschluss-Stutzen oder die Öffnungen in der Packung mit einer speziellen Folie, zum Beispiel einer Aluminiumfolie, gasdicht verschlossen werden und erst beim erstmaligen Öffnen diese Folie aufgeschnitten oder herausgebrochen wird. Hierzu bestehen die Verschluss-Systeme aus drei Teilen: Einem Stutzen, der auf die Packung montiert wird, einer im Stutzen geführten Schneidhülse sowie einer Stutzenkappe. Beim Wegschrauben der Stutzenkappe dreht diese die Schneidhülse mit, die sich sodann nach unten verschiebt und die gasdichte Folie aufschneidet. Es sind auch Lösungen bekannt, bei denen eine gasdichte Folie nachträglich auf den oberen Stutzenrand aufgesiegelt wird und dann die Stutzenkappe aufgeprellt wird. Der Benützer muss dann nach dem Wegschrauben der Kappe die Siegelfolie gesondert wegreissen und gesondert entsorgen. Oftmals wird aber die weggerissene Siegelfolie achtlos weggeworfen. Nach dem Wegreissen und Entsorgen der Siegelfolie muss die Kappe wieder aufgeschraubt werden und eine Ausgussklappe wird dann daran aufgeklappt, wonach erst der Verschluss zum Ausgiessen bereit ist. Der Öffnungsvorgang erfordert daher mehrere Schritte. Selbst wenn auf solche Stutzenöffnungen eine gasdichte Folie aufgesiegelt wird, so bleibt doch eine gewisse Gaspermeabilität aufgrund des Kunststoff-Materials bestehen und ein geringes Durchdiffundieren von Sauerstoff durch die Stutzenwandung ist unvermeidar.
Dokument FR-A-2- 779 418 offenbart einen gasdichten Stutzenverschluß mit einer Drehplatte mit Zähmen zur Durchbrechung den Verpackung.One approach is to seal the closure sockets or the openings in the package with a special foil, for example an aluminum foil, in a gas-tight manner, and only when this foil is opened for the first time will this foil be cut open or broken out. For this purpose, the closure systems consist of three parts: a nozzle, which is mounted on the package, a guided in the nozzle cutting sleeve and a nozzle cap. When unscrewing the nozzle cap this rotates with the cutting sleeve, which then moves down and cuts the gas-tight film. There are also known solutions in which a gas-tight film is subsequently sealed onto the upper nozzle edge and then the nozzle cap is aufgeprellt. The user must then after unscrewing the cap the sealing film tear away separately and dispose of separately. Often, however, the torn-off sealing foil is thrown away carelessly. After the removal and disposal of the sealing foil, the cap must be screwed on again and a spout is then unfolded, after which only the closure is ready for pouring. The opening process therefore requires several steps. Even if such a nozzle openings a gas-tight film is sealed, yet there remains a certain gas permeability due to the plastic material and a low Durchdiffundieren of oxygen through the Stutzenwandung is inevitable.
document FR-A-2-779418 discloses a gas-tight neck closure with a rotary plate tame to break the packaging.

Die Aufgabe der vorliegenden Erfindung ist es, einen gasdichten Stutzenverschluss mit Öffnungseinrichtung anzugeben, welcher die geforderte Gasdichtigkeit bietet, welcher aus nur zwei Teilen besteht und welcher eine automatische Öffnungseinrichtung für ein einfaches Öffnen einschliesst. In einer Variante soll durch das erstmalige Öffnen des Stutzenverschlusses keine gesondert zu entsorgende Dichtfolie anfallen. In einer weiteren Variante soll der Stutzenverschluss auch eine von aussen prüfbare Erstöffnungsgarantie bieten.The object of the present invention is to provide a gas-tight neck closure with opening device, which provides the required gas-tightness, which consists of only two parts and which includes an automatic opening device for easy opening. In one variant, should be incurred by the first-time opening of the neck closure no separately to be disposed of sealing film. In another variant, the neck closure should also offer an externally testable first-opening guarantee.

Diese Aufgabe wird gelöst von einem gasdichten Stutzenverschluss mit Öffnungseinrichtung, bestehend aus einem Stutzen mit zugehöriger Stutzenkappe, der sich dadurch auszeichnet, dass der Stutzen in seiner lichten Öffnung einstückig von einer Dichtplatte verschlossen ist und an der Unterseite der Stutzenkappe ein in die lichte Öffnung des Stutzens einpassender Ring angeformt ist, und dass zusammenwirkende Führungsmittel an Stutzenaussenseite und Kappeninnenseite vorhanden sind, sodass beim Drehen der Stutzenkappe in Öffnungsrichtung dieselbe mit ihrem Ring unter Herausbrechen der Dichtplatte durch denselben zunächst ein stückweit gegen den Stutzen hin pressbar ist und hernach vom Stutzen entfernbar ist.This object is achieved by a gas-tight neck closure with opening device, consisting of a nozzle with associated nozzle cap, which is characterized in that the nozzle is integrally sealed in its clear opening of a sealing plate and at the bottom of the nozzle cap in the clear opening of the nozzle fitting ring is formed, and that cooperating guide means on Stutzenaussenseite and cap inside are present, so that upon rotation of the nozzle cap in the opening direction the same with its ring under the breaking out of the sealing plate by the same first a piece pressed against the nozzle and afterwards it is removable from the nozzle.

In Figur 1 ist der gasdichte Stutzenverschluss in geschlossenem Zustand dargestellt, wobei er in dieser Abbildung in eine unten befüllte Getränkedose 2 integriert ist. Diese Getränkdose 2 wird nach dem Befüllen in gestürztem Zustand mit dem ebenfalls dargestellten Dosenboden 3 versiegelt. Der Stutzenverschluss besteht aus einem Stutzen 15, der hier nicht sichtbar ist und im gezeigten Beispiel einstückig zur Getränkedose 2 gehört, und weiter einer zugehörigen Stutzenkappe 1, die hier auf den Stutzen 15 aufgesetzt ist. Der Stutzenverschluss aus Stutzen 15 und Stutzenkappe 1, das heisst der hier oberhalb der Trennlinie eingezeichnete Teil, kann selbstverständlich auch an anderen Verpackungen eingesetzt werden, zum Beispiel an Kartonverpackungen, an Flaschen und anderen Gebinden.In FIG. 1 the gas-tight neck closure is shown in the closed state, where he in this figure in a bottom filled beverage can. 2 is integrated. This beverage can 2 is sealed after filling in the toppled state with the can bottom 3 also shown. The nozzle closure consists of a nozzle 15, which is not visible here and in the example shown is integral with the beverage can 2, and further an associated nozzle cap 1, which is placed here on the nozzle 15. Of course, the neck closure from neck 15 and neck cap 1, that is to say the part shown here above the dividing line, can also be used on other packagings, for example on cardboard packagings, on bottles and other containers.

In Figur 2 ist dieser Stutzenverschluss ohne Stutzenkappe an dieser Getränkedose 2 gezeigt. So präsentiert sich der eigentliche Stutzen 15 vor dem Aufsetzen der Stutzenkappe. Er ist gasdicht ausgeführt, indem er mittels einer bekannten Co-Injektionstechnik gespritzt wird. Dabei wird ein Barrierematerial aus zum Beispiel EVOH oder PA als Spritzkomponente, die allseits von zwei weiteren Spritzkomponenten umschlossen ist, in die Kavität des Spritzwerkzeuges eingespritzt, sodass hernach eine Barriereschicht im Innern des Stutzens 15 gebildet ist und dieser somit gasundurchlässig wird. Als Besonderheit erkennt man aussen am Kragen des Stutzens 15 um den Umfang verteilt angeordnete, radial abstehende Führungsnocken 4. Weiter ist die lichte Öffnung des Stutzens 15 von einer Dichtplatte 5 verschlossen. Diese Dichtplatte 5 besteht nicht bloss aus einer dünnen Folie, sondern besteht aus einer stabilen Platte, die an ihrem Aussenrand allerdings über eine Dünnstelle mit der Stutzeninnenwand einstückig verbunden ist. Konzentrisch auf dieser Dichtplatte 5 ist eine Ringwand 6 angeordnet, deren Funktion im weiteren Verlauf der Beschreibung noch klar wird.In FIG. 2 this nozzle closure without nozzle cap is shown on this beverage can 2. Thus, the actual nozzle 15 presents before placing the nozzle cap. It is gas-tight by being sprayed by means of a known co-injection technique. In this case, a barrier material of, for example, EVOH or PA as an injection component, which is surrounded on all sides by two further injection components, injected into the cavity of the injection mold, so that afterwards a barrier layer is formed in the interior of the nozzle 15 and this is thus gas impermeable. A special feature can be seen on the outside of the collar of the nozzle 15 distributed around the circumference arranged, radially projecting guide cam 4. Next, the clear opening of the nozzle 15 is closed by a sealing plate 5. This sealing plate 5 is not only made of a thin film, but consists of a stable plate, which is integrally connected at its outer edge, however, via a thin point with the nozzle inner wall. Concentric on this sealing plate 5, an annular wall 6 is arranged, whose function will become clear in the further course of the description.

In Figur 3 ist nun die zugehörige Stutzenkappe 1 dargestellt, und zwar hier von unten gesehen, also in gestürzter Lage. An der Innenseite des Deckels der Stutzenkappe erkennt man einen konzentrisch angeordneten Schnappring 7. Beim Aufsetzen der Stutzenkappe 1 passt dieser Schnappring 7 über die Ringwand 6 auf der Dichtplatte 5 des Stutzens 15 und schnappt an derselben ein, wie das noch aufgezeigt wird. Weiter ist auf der Innenseite des Deckels der Stutzenkappe 1 ein Schneidring 8 konzentrisch angeordnet. Dieser Schneidring 8 bildet unten einen gezahnten Rand. Bei aufgesetzter Stutzenkappe 1 passt dieser Schneidring 8 genau in das Stutzeninnere und schliesst an die Stutzeninnenwand an. Weiter erkennt man in der Innenwand der Stutzenkappe 1 besondere, eingelassene Nuten, welche als Führungskulissen 9 für die an der Aussenseite des Stutzens 15 angeordneten, radial abstehenden Nocken 4 zu wirken bestimmt sind. Die Führungskulissen 9 weisen einen an der Kappe 1 leicht ansteigenden Abschnitt auf, der anschliessend in einen etwa im 45°-Winkel abwärts geneigten Abschnitt übergeht. Etwa in der Mitte der leicht ansteigenden Abschnitte sind herausbrechbare Garantieplättchen 10 angeordnet, die auf ihrer hier dem Betrachter zugewandten Innenseite der Stutzenkappe 1 einen Kugelabschnitt aufweisen und daher bombiert sind. Auf der Aussenseite der Stutzenkappe 1 verlaufen diese Garantieplättchen 10 bündig mit der Kappenaussenseite, die ansonsten gerillt oder gerändelt ausgeführt ist, um für den Benützer einen guten Griff zu bieten. Der untere, hier dem Betrachter zugewandte Rand der Stutzenkappe 1 weist gegenüber den Enden der Führungsnuten 9 Abschrägungen 11 auf. Mit Hilfe dieser Abschrägungen 11 lässt sich die Stutzenkappe 1 über die Nocken 4 am Stutzen 15 auf denselben stülpen. Die Nocken 4 gleiten dann über die Abschrägungen 11 und längs der Kappen-Innenwand in die Führungsnuten 9 und schnappen darin ein.In FIG. 3 now the associated nozzle cap 1 is shown, and seen here from below, ie in a crashed position. On the inside of the lid of the nozzle cap can be seen a concentrically arranged snap ring 7. When placing the nozzle cap 1 fits this snap ring 7 on the annular wall 6 on the sealing plate 5 of the nozzle 15 and snaps on the same, as will be shown. Further, a cutting ring 8 is concentrically arranged on the inside of the lid of the nozzle cap 1. This cutting ring 8 forms a toothed edge below. With attached cap 1, this cutting ring fits 8 exactly in the nozzle interior and connects to the nozzle inner wall. Next you can see in the inner wall of the nozzle cap 1 special, sunken grooves, which are determined to act as guide slots 9 for arranged on the outside of the nozzle 15, radially projecting cam 4. The guide slots 9 have a slightly rising on the cap 1 section, which then merges into an approximately at 45 ° angle downwardly inclined portion. About in the middle of the slightly rising sections breakable guarantee tiles 10 are arranged, which have on their here facing the viewer inside of the nozzle cap 1 a ball portion and are therefore cambered. On the outside of the neck cap 1, these guarantee tiles 10 are flush with the outside of the cap, which is otherwise grooved or knurled to provide a good grip for the user. The lower, here the viewer facing edge of the nozzle cap 1 has 9 bevels 11 relative to the ends of the guide grooves. With the help of these chamfers 11, the nozzle cap 1 can be put over the cams 4 on the nozzle 15 on the same. The cams 4 then slide over the chamfers 11 and along the cap inner wall into the guide grooves 9 and snap into it.

Die Figur 4 zeigt die Stutzenkappe 1 von oben gesehen. Man erkennt die Abschrägungen 11 unteren Rand, hier von aussen gesehen, sowie die gerillte äussere Umfangswand und die darin über feine Materialbrücken gehaltenen, herausbrechbaren Garantieplättchen 10.The FIG. 4 shows the neck cap 1 seen from above. It can be seen the bevels 11 lower edge, seen from the outside, and the grooved outer peripheral wall and held therein over fine material bridges, break-out Guarantee tiles 10th

Die Figur 5 zeigt die aus der Innenwand der Stutzenkappe 1 ausgenommene Nut 9, welche als Führungskulisse für einen Nocken 4 wirkt, anhand eines Querschnitts. In dieser vergrösserten Darstellung lässt sich die Ausgestaltung der Garantieplättchen 10 ersehen, die auf ihrer Innenseite eine kugelige Oberfläche aufweisen und im gezeigten Beispiel über vier feine Materialbrücken in der Stutzenkappenwand gehalten sind. Darunter erkennt man eine der Abschrägungen 11 als Einlaufführung für die Nocken 4. Weiter erkennt man an der Deckelinnenseite den Schnappring 7 sowie den Schneidring 8 mit seinem gezahntem Schneiderand. Wie man sieht, ist auf der Innenseite des unteren Randes des Schnapprings 7 ein Wulst 14 ausgeformt, mit welchem der Schnappring 7 an der Ringwand 6 auf der Dichtplatte 5 des Stutzens 15 einschnappen kann.The FIG. 5 shows the recessed from the inner wall of the nozzle cap 1 groove 9, which acts as a guide link for a cam 4, based on a cross section. In this enlarged view, the design of the warranty tiles 10 can be seen, which have on their inside a spherical surface and are held in the example shown on four fine material bridges in the neck cap wall. One recognizes one of the bevels 11 as an inlet guide for the cam 4. Next you can see on the inside of the lid, the snap ring 7 and the cutting ring 8 with its toothed cutting edge. As you can see, it is on the inside of the bottom edge of the snap ring 7 a bead 14 formed with which the snap ring 7 can snap on the annular wall 6 on the sealing plate 5 of the nozzle 15.

In Figur 6 ist der Stutzenverschluss in geschlossenem Zustand in einem Querschnitt längs der Rotationsachse des Stutzens 15 und der Kappe 1 dargestellt. Die Stutzenkappe 1 wurde von oben axial auf den Stutzen 15 aufgeschoben. Dabei sind die radial von der Stutzenaussenseite abstehenden Nocken 4 über die Abschrägungen 11 aufgelaufen und schnappten wie hier sichtbar gemacht in den Nuten 9 bzw. Führungskulissen in der Innenseite der Kappenwand ein. Die Hinterschneidungen 13 sorgen dafür, dass die Stutzenkappe 1 nicht wieder vom Stutzen 15 in axialer Richtung abgezogen werden kann. In dieser aufgesetzten oder aufgepressten Lage der Stutzenkappe 1 liegt der Schneidring 8 satt an der Innenseite des Stutzens 15 an. Der Schnappring 7 andrerseits wurde über die Ringwand 6 gestülpt und der Aussenwulst an dieser Ringwand 6 schnappt hinter dem Innenwulst 14 am Schnappring 7 ein. Trotz dieser Schnappverbindung lässt sich aber der Schnappring 7 gegenüber der Ringwand 6 um die Rotationsachse des Stutzens 15 bzw. der Kappe 1 verdrehen. Ebenso könnte anstelle des Überstülpens des Schnappringes 7 über die Ringwand 6 der Schnappring 7 auch in das Innere der Ringwand 6 einpassen und die Schnappverbindung wäre dann durch einen Aussenwulst am Schnappring und einen Innenwulst an der Ringwand realisiert. Wie man anhand dieser Schnittdarstellung erkennt, ist die Dichtplatte 5, welche sich über die lichte Öffnung des Stutzens 15 erstreckt, an ihrem Rand über eine umlaufende Dünnstelle 12 mit der Innenwand des Stutzens 15 einstückig verbunden. In der nächsten Figur wird aufgezeigt, wie dieser Verschluss nun geöffnet wird.In FIG. 6 the nozzle closure in the closed state in a cross section along the axis of rotation of the nozzle 15 and the cap 1 is shown. The nozzle cap 1 was slid axially from above onto the nozzle 15. The protruding radially from the outside of the nozzle cams 4 accumulated on the chamfers 11 and snapped as made visible here in the grooves 9 and guide slots in the inside of the cap wall. The undercuts 13 ensure that the neck cap 1 can not be withdrawn again from the nozzle 15 in the axial direction. In this patch or pressed-on position of the neck cap 1 of the cutting ring 8 is full on the inside of the nozzle 15. The snap ring 7 on the other hand was slipped over the annular wall 6 and the outer bead on this annular wall 6 snaps behind the inner bead 14 on the snap ring 7 a. Despite this snap connection but can the snap ring 7 relative to the annular wall 6 rotate about the axis of rotation of the nozzle 15 and the cap 1. Likewise, instead of the over-insertion of the snap ring 7 on the annular wall 6 of the snap ring 7 also fit into the interior of the annular wall 6 and the snap connection would then be realized by an outer bead on the snap ring and an inner bead on the annular wall. As can be seen from this sectional view, the sealing plate 5, which extends over the clear opening of the nozzle 15, is integrally connected at its edge via a circumferential thin spot 12 with the inner wall of the nozzle 15. The next figure shows how this shutter is opened.

Hierzu zeigt die Figur 7 den Stutzenverschluss beim Öffnungsvorgang, wobei die Stutzenkappe 1 in einem Querschnitt längs ihrer Rotationsachse dargestellt ist, um einen Einblick in das Innere des Verschlusses zu gewähren. Zum Öffnen wird die Stutzenkappe 1 im Gegenuhrzeigersinn gedreht. Infolge der leicht ansteigenden Führungskulissen 9 an der Innenwand der Stutzenkappe 1 wird diese gleichzeitig zur Verdrehung in axialer Richtung gegen den Stutzen 15 hin bewegt. Dabei drückt der gezahnte untere Rand des Schneidringes 8 drehend auf die Dünnstelle 12 um die Dichtplatte 5 und schert diese unter der herrschenden Punktlast ab. Nach dieser Abscherung befinden sich die Nocken 4 an der Knickstelle der Führungskulisse 9, die nun in einem ca. 45°-Winkel abfällt. Bei weiterem Drehen der Stutzenkappe 1 wird dieselbe deshalb in axialer Richtung vom Stutzen 15 wegbewegt und lässt sich schliesslich von diesem abziehen. Wegen der beim erstmaligen Aufsetzen der Stutzenkappe 1 entstandenen Schnappverbindung zwischen dem Schnappring 7 an der Stutzenkappe 1 und der Ringwand 8 an der Dichtplatte 5 verbleibt die Dichtplatte 5 an der Stutzenkappe 1 und wird von derselben weiterhin gehalten.This shows the FIG. 7 the neck closure during the opening process, wherein the neck cap 1 is shown in a cross section along its axis of rotation, to provide an insight into the interior of the closure. To open the neck cap 1 is rotated counterclockwise. As a result of the slightly rising guide slots 9 on the inner wall of the nozzle cap. 1 This is simultaneously moved to rotate in the axial direction against the nozzle 15. The toothed lower edge of the cutting ring 8 rotatably presses on the thin spot 12 around the sealing plate 5 and shears it off under the prevailing point load. After this shearing, the cams 4 are at the bend of the guide slot 9, which now drops in an approximately 45 ° angle. Upon further rotation of the nozzle cap 1, the same is therefore moved away from the nozzle 15 in the axial direction and can finally be deducted from this. Because of the snap connection formed between the snap ring 7 on the neck cap 1 and the annular wall 8 on the sealing plate 5 during the initial placement of the neck cap 1, the sealing plate 5 remains on the neck cap 1 and continues to be held by the same.

Die Figur 8 zeigt den Stutzenverschluss in geschlossenem Zustand in einem Horizontalschnitt durch die Stutzenkappe 1 und den Stutzen 15. Der Schnitt verläuft dabei gerade oberhalb der Nocken 4. Dadurch ist in dieser Abbildung die Lage der Nocken 4 sowie der Garantieplättchen 10 nach dem erstmaligen Aufsetzen der Stutzenkappe 1 auf den Stutzen 15 einsichtig. Beim erstmaligen Öffnen des Verschlusses werden durch das Drehen der Stutzenkappe 1 im Gegenuhrzeigersinn die Garantieplättchen 10 über die Nocken 4 gefahren und daher brechen zwei bis drei der feinen Materialbrücken und die Garantieplättchen 10 werden in der Folge etwas nach aussen geschwenkt, aber immer noch an einer oder zwei Materialbrücken festgehalten. Die Stutzenkappe 1 kann dann weiter im Gegenuhrzeigersinn gedreht werden, wodurch wie oben beschrieben die Dichtplatte 5 aus dem Stutzen 15 herausgebrochen wird, und wonach die Stutzenkappe 1 dann nach weiterem Losdrehen mitsamt der herausgebrochenen Dichtplatte 5 vom Stutzen 15 abgezogen werden kann.The FIG. 8 shows the neck closure in the closed state in a horizontal section through the neck cap 1 and the nozzle 15. The section runs just above the cam 4. Thus, in this figure, the position of the cam 4 and the guarantee plate 10 after the first attachment of the neck cap 1 the nozzle 15 reasonable. When opening the shutter for the first time by turning the neck cap 1 counterclockwise the warranty tiles 10 are driven over the cam 4 and therefore break two to three of the fine material bridges and the guarantee tiles 10 are pivoted slightly outwards in the sequence, but still at one or two bridges of material held. The nozzle cap 1 can then be rotated further counterclockwise, which as described above, the sealing plate 5 is broken out of the pipe 15, and then the nozzle cap 1 can then be withdrawn after further loosening together with the broken-off sealing plate 5 from the nozzle 15.

In Figur 9 ist die abgezogene Stutzenkappe 1 von unten gesehen gezeigt. In ihrem Innern hält sie die herausgestanzte bzw. abgescherte Dichtplatte 5 fest, sodass diese nicht als Wegwerfteil achtlos irgendwo liegenbleibt, sondern später zusammen mit der ganzen Dose und ihrem Verschluss korrekt entsorgt wird. Nach der Öffnung des Stutzenverschlusses präsentiert sich die Getränkedose wie in Figur 10 dargestellt. Wenn die Stutzenkappe 1 erneut auf den Stutzen 15 aufgesetzt wird, so passt der Schneidring 8 exakt in den Stutzen 15 und dichtet gegenüber der Stutzeninnenwand ab. Ausserdem schnappen dabei die Nocken 4 erneut in der Führungskulisse 9 ein und die Kappe 1 ist auf dem Stutzen 15 vor unbeabsichtigtem Abziehen gesichert. Anstatt die Kappe 1 über die Anschrägungen 11 auf den Stutzen 15 aufzudrücken, kann die Kappe 1 auch im umgekehrten Sinn wie beim erstmaligen Öffnen, das heisst im Uhrzeigersein auf den Stutzen 15 gedreht werden. Der Verschluss ist hernach wieder dicht und die Kappe 1 auf dem Stutzen gesichert.In FIG. 9 the withdrawn neck cap 1 is seen from below. Inside it holds the punched out or sheared sealing plate 5 so that it does not lie left as a disposable careless anywhere, but later disposed of properly together with the whole can and its closure. After opening the neck closure, the beverage can presents itself as in FIG. 10 shown. When the neck cap 1 again on the neck 15 is placed, the cutting ring 8 fits exactly into the nozzle 15 and seals against the nozzle inner wall. In addition, while snapping the cam 4 again in the guide slot 9 and the cap 1 is secured to the nozzle 15 against accidental removal. Instead of pressing the cap 1 over the chamfers 11 on the neck 15, the cap 1 can also be rotated in the reverse direction as the first time opening, that is, in Uhrzeigersein on the neck 15. The closure is then tight again and the cap 1 secured on the neck.
