  • the present invention relates to a closure for direct or indirect application to a container neck which is closed directly or indirectly by a push-through membrane or film.
  • a film or membrane provides a guarantee for the end user that the contents of the container correspond to what the supplier has filled in.
  • Screw locks which are secured against unscrewing for the first time offer greater security.
  • Such screw closures are known. So that the cap cannot be unscrewed easily, it is provided with a guarantee band, which is connected to the container neck like a riddle. This prevents the cap from being unscrewed as long as the guarantee band is intact. The cap can only be unscrewed after the guarantee tape has been torn off and removed.

  • EU PS 0050 490 specifies a further development. After the guarantee tape has been removed, the cap can be screwed on further and grips under the edge of an upper, detachable part of the container neck. When the cap is unscrewed for the first time, the cap tears off the detachable part from the neck of the container.
  • the invention has for its object to provide a container closure that can be used in containers, the content of which is guaranteed against contact by means of a membrane or film.
  • it should be user-friendly and, instead of a simple screw cap, have a pouring opening which can be closed by a captive cap with a hinge. Handling should be as simple as possible, so that no detailed instructions for use are required.
  • the invention solves this problem with a closure of the type mentioned, which has the specific features of claim 1.
  • the closure must be able to assume two layers, namely a higher position with respect to the neck of the container, in which the film or membrane is intact, and a lower position, in which the film or membrane is pierced or cut through. These two positions are referred to below as the “guarantee position” or “use position” of the closure.
  • Claim 2 proposes to bring the closure into the position of use by screwing it from the guarantee position (after tearing off or breaking off the guarantee band).
  • the closure can be brought from the guarantee position into the position of use by axially pushing on or pushing (also after tearing off or breaking off the guarantee band).
  • Figures 1.1a, 1b show a screw-on plastic hinge closure with a cap 1 and a lower part 2, which are connected to one another by a film hinge 3 known per se.
  • This actual closure is not directly connected to the container 5 by means of an annular intermediate piece 4.
  • the intermediate piece has an internal thread 41 and an external thread 42. With the internal thread it is fastened on the container neck 51.
  • the actual closure 1, 2, 3 is screwed onto the external thread 42 of the intermediate piece.

Abstract

Der aus Kunststoff hergestellte Verschluss findet Verwendung bei einem Behälter dessen Hals durch eine durchstechbare Membran (6) verschlossen ist. Die unversehrte Membran bildet eine Garantie dafür, dass der Behälterinhalt der Original­füllung entspricht. Ein Durchstechen der Membran wird dadurch erreicht, dass der Verschluss als Ganzes zwei Höhenlagen bezüglich des Behälterhalses einnehmen kann. Die höhere Lage wird durch ein abreissbares Garantieband (44,45) gesichert. Erst nach dem Abreissen des Garantiebandes kann der Verschluss als Ganzes durch Aufschrauben in die tiefere Lage gebracht werden wobei zugleich die Membrane (6) durch­stossen wird. Das Garantieband ist an seiner Innenseite mit einer rätschenartigen Verzahnung (44) versehen, die ein Ab­schrauben des Verschlusses verunmöglicht. Das Garantieband ist an einem separaten Zwischenstück (4) angebracht, das auf den Behälterhals (51) augesprengt ist und die Membran (6) überdeckt. Das Zwischenstück ist aussen mit einem Gewinde (42) versehen und trägt oben die Mittel (43), welche dazu dienen die Membran (6) zu durchstechen.

The closure made of plastic is used in a container whose neck is closed by a pierceable membrane (6). The intact membrane guarantees that the contents of the container correspond to the original filling. Piercing of the membrane is achieved in that the closure as a whole can take up two positions with respect to the neck of the container. The higher location is secured by a tear-off guarantee tape (44.45). Only after tearing off the guarantee tape can the closure as a whole be screwed into the lower position, at the same time piercing the membrane (6). The inside of the guarantee band is provided with a riddle-like toothing (44) which prevents the closure from being unscrewed. The guarantee band is attached to a separate intermediate piece (4) which is blasted onto the container neck (51) and covers the membrane (6). The intermediate piece is provided with a thread (42) on the outside and carries at the top the means (43) which serve to pierce the membrane (6).

Description

Die vorliegende Erfindung bezieht sich auf einen Verschluss zum direkten oder mittelbaren Aufbringen auf einen, durch eine durchsteckbare Membran oder Folie direkt oder mittelbar verschlossenen Behälterhals. Eine solche Folie oder Membran bildet für den Endverbrauch eine Garantie, dass der Inhalt des Behälters dem entspricht was der Lieferant eingefüllt hat. Ausserdem trägt sie durch absoluten Luftabschluss dazu bei, dass keine Oxydation des abgefüllten Produktes stattfinden kann.The present invention relates to a closure for direct or indirect application to a container neck which is closed directly or indirectly by a push-through membrane or film. Such a film or membrane provides a guarantee for the end user that the contents of the container correspond to what the supplier has filled in. In addition, due to the absolute absence of air, it contributes to the fact that no oxidation of the filled product can take place.

Bekannt sind einfache Verschlüsse mit einer auf dem Behälterhals aufschraubbaren Kappe unten der sich eine von Hand oder mit einem Hilfswerkzeug zu durchstechende Folie befindet. Ein solcher Verschluss bietet, ohne Nachprüfung dem Endabnehmer keine Garantie, dass der Inhalt unversehrt ist. Er müsste dazu erst die Kappe abschrauben!Simple closures are known with a screw-on cap on the container neck below which is a film to be pierced by hand or with an auxiliary tool. Without a check, such a closure does not guarantee the end customer that the Content is intact. He would have to unscrew the cap first!

Grössere Sicherheit bieten Schraubverschlüsse die gegen ein erstes Abschrauben gesichert sind. Derartige Schraubverschlüsse sind bekannt. Damit die Kappe nicht ohne weiteres abgeschraubt werden kann ist sie mit einem Garantieband versehen, das rätschenartig mit dem Behälterhals in Verbindung steht. Dadurch wird das Abschrauben der Verschlusskappe verhindert solange das Garantieband unversehrt ist. Erst nachdem das Garantieband abgerissen und entfernt worden ist, kann die Kappe abgeschraubt werden. Zur Dokumentation sei auf die DE-A 24 56 931, 29 04 181, 29 23 379, 29 52 779 und 32 02 226 verwiesen.Screw locks which are secured against unscrewing for the first time offer greater security. Such screw closures are known. So that the cap cannot be unscrewed easily, it is provided with a guarantee band, which is connected to the container neck like a riddle. This prevents the cap from being unscrewed as long as the guarantee band is intact. The cap can only be unscrewed after the guarantee tape has been torn off and removed. For documentation, reference is made to DE-A 24 56 931, 29 04 181, 29 23 379, 29 52 779 and 32 02 226.

Eine Weiterentwicklung gibt die EU-PS 0050 490 an. Nachdem das Garantieband entfernt ist, kann die Kappe weiter aufgeschraubt werden und fasst dabei unter den Rand eines oberen, absprengbaren Teiles des Behälterhalses. Beim erstmaligen Abschrauben der Kappe reisst die Kappe den absprengbaren Teil vom Behälterhals ab.EU PS 0050 490 specifies a further development. After the guarantee tape has been removed, the cap can be screwed on further and grips under the edge of an upper, detachable part of the container neck. When the cap is unscrewed for the first time, the cap tears off the detachable part from the neck of the container.

Sämtliche bisher bekannten Massnahmen zur Erhöhung der Sicherheit für die Unberührtheit des Behälterinhaltes, stehen im direkten Widerstreit mit der gewünschten Bequemlichkeit beim Gebrauch. Will man vom Behälterinhalt Gebrauch machen, muss jedesmal die Kappe abgeschraubt und danach wieder aufgeschraubt werden. Es besteht dabei die Gefahr, dass die abgeschraubte Kappe verloren geht, so dass der Behälter nicht mehr verschlossen werden kann und der Inhalt verdirbt oder in seiner Qualität beeinträchtigt wird.All previously known measures to increase the security for the untouchedness of the container contents are in direct conflict with the desired convenience in use. If you want to use the container contents, you have to unscrew the cap each time and then screw it back on. There is a risk that the unscrewed cap is lost, so that the container can no longer be closed and the contents spoil or its quality is impaired.

Die Erfindung stellt sich zur Aufgabe einen Behälterverschluss zu schaffen, der bei Behältern verwendet werden kann, deren Inhalt mittels einer Membran oder Folie gegen Unberührtheit garantiert ist. Zudem soll er gebraucherfreundlich sein, und statt einer einfachen Abschraubkappe eine Ausgussöffnung aufweisen, die durch eine unverlierbare Kappe mit Scharnier verschlossen werden kann. Die Handhabung soll möglichst einfach sein, so dass keine ausführliche Gebrauchsanweisung erforderlich ist.The invention has for its object to provide a container closure that can be used in containers, the content of which is guaranteed against contact by means of a membrane or film. In addition, it should be user-friendly and, instead of a simple screw cap, have a pouring opening which can be closed by a captive cap with a hinge. Handling should be as simple as possible, so that no detailed instructions for use are required.

Die Erfindung löst diese Aufgabe mit einem Verschluss der eingangs genannten Art, der die spezifischen Merkmale des Patentanspruches 1 aufweist.The invention solves this problem with a closure of the type mentioned, which has the specific features of claim 1.

Der Verschluss muss prinzipiell in der Lage sein zwei Lagen einzunehmen, nämlich einer bezüglich des Behälterhalses höhere Lage, bei dem die Folie oder Membran unversehrt ist und eine tiefere Lage bei dem die Folie oder Membran durchstochen oder durchschnitten ist. Diese beiden Lagen werden im Folgenden als "Garantielage" beziehungsweise "Gebrauchslage" des Verschlusses bezeichnet.In principle, the closure must be able to assume two layers, namely a higher position with respect to the neck of the container, in which the film or membrane is intact, and a lower position, in which the film or membrane is pierced or cut through. These two positions are referred to below as the "guarantee position" or "use position" of the closure.

Die Erfindung bietet dazu zwei Varianten an. Patentanspruch 2 schlägt vor den Verschluss durch eine Schraubwirkung von der Garantielage (nach Abreissen oder Absprengen des Garantiebandes) in die Gebrauchslage zu bringen. Gemäss Patentanspruch 3 lässt sich der Verschluss durch axiales Aufschieben oder Stossen (ebenfalls nach Abreissen oder Absprengen des Garantiebandes) von der Garantielage in die Gebrauchslage bringen.The invention offers two variants for this. Claim 2 proposes to bring the closure into the position of use by screwing it from the guarantee position (after tearing off or breaking off the guarantee band). According to claim 3, the closure can be brought from the guarantee position into the position of use by axially pushing on or pushing (also after tearing off or breaking off the guarantee band).

In der Zeichnung sind einige Ausführungsbeispiele des Erfindungsgegenstandes dargestellt:

  • Figur 1 zeigt einen Schraubverschluss in Garantielage;
  • Figur 1a denselben Verschluss in Gebrauchslage und
  • Figur 1b den Verschluss nach Figur 1a mit geöffneter Verschlusskappe

  • Figur 5 ein Zwischenstück für sich und einen Behälter, dessen Hals so geformt ist, dass das Zwischenstück auf den Hals aufgepresst oder aufgesprengt werden kann.
Some exemplary embodiments of the subject matter of the invention are shown in the drawing:
  • Figure 1 shows a screw cap in the guaranteed position;
  • Figure 1a the same closure in the position of use and
  • 1b the closure according to FIG. 1a with the closure cap open
  • Figure 2 shows a closure in the guaranteed position, which can be brought into the position of use by axial pushing or pushing;
  • Figure 2a shows the closure of Figure 2 in the use position;
  • Figure 2b the same closure with the cap open;

Die Figuren 1,1a,1b zeigen einen aufschraubbaren Kunsttoff-Scharnierverschluss mit einer Kappe 1 und einem Unterteil 2, die durch ein an sich bekanntes Filmscharnier 3 miteinander verbunden sind. Dieser eigentliche Verschluss ist nicht direkt, sondern mittels eines ringförmigen Zwischenstücks 4 mit dem Behälter 5 verbunden. Das Zwischenstück hat ein Innengewinde 41 und ein Aussengewinde 42. Mit dem Innengewinde ist es auf den Behälterhals 51 befestigt. Auf das Aussengewinde 42 des Zwischenstückes ist der eigentliche Verschluss 1,2,3 aufgeschraubt. Zwischen dem oberen Rand des Flaschenhalses 51 und dem Zwischenstück 4 ist eine Folie 6 angebracht, die mit dem Rand des Behälterhalses und gegebenenfalls zusätzlich mit dem Zwischenstück 4 versiegelt, verschweisst oder angeklebt ist. Das Zwischenstück 4 ist mit einem Oeffnungsorgan 43 versehen das sich in Garantielage nach Figur 1 oberhalb der Folie 6 befindet. Wird der Verschluss von der Garantielage in die Gebrauchslage nach Figur 1a gebracht, betätigt ein hohler Stössel 21 das Oeffnungsgrad 43 und bringt es in die in Figur 1a dargestellte Lage 43' bei der es die Folie 6 aufgeschnitten und weggedrückt hat.Figures 1.1a, 1b show a screw-on plastic hinge closure with a cap 1 and a lower part 2, which are connected to one another by a film hinge 3 known per se. This actual closure is not directly connected to the container 5 by means of an annular intermediate piece 4. The intermediate piece has an internal thread 41 and an external thread 42. With the internal thread it is fastened on the container neck 51. The actual closure 1, 2, 3 is screwed onto the external thread 42 of the intermediate piece. A film 6 is attached between the upper edge of the bottle neck 51 and the intermediate piece 4, which is sealed, welded or glued to the edge of the container neck and optionally additionally to the intermediate piece 4. The intermediate piece 4 is provided with an opening member 43 which is in the guarantee position according to FIG. 1 above the film 6. If the closure is brought from the guarantee position into the use position according to FIG. 1a, a hollow plunger 21 actuates the degree of opening 43 and brings it into the position 43 'shown in FIG. 1a, in which it has cut open the film 6 and pushed it away.

Der Unterteil 2 ist wie oben erwähnt mit einem hohlen Stössel 21 versehen, der an die Ausgussöffnung 22 anschliesst. In der Gebrauchslage nach Figur 1a liegt der ringförmige Vorsprung 23 auf dem Zwischenstück 4 auf und bestimmt die exakte Lage des Verschlusses bezüglich des Zwischenstückes. Die Kappe 1 ist mit einem Schliessring 11 versehen, der bei geschlossener Kappe die Ausgussöffnung 22 verschliesst.As mentioned above, the lower part 2 is provided with a hollow plunger 21 which adjoins the pouring opening 22. In the position of use according to FIG. 1a, the annular projection 23 lies on the intermediate piece 4 and determines the exact position of the closure with respect to the intermediate piece. The cap 1 is provided with a locking ring 11 which closes the pouring opening 22 when the cap is closed.

Damit der Verschluss nicht ohne weiteres von der Garantielage (Figur 1) in die Gebrauchslage (Figur 1a) gebracht werden kann, ist am Zwischenstück ein Garantieband 44 angebracht und durch eine Sollbruchnaht 45 damit verbunden. An der Innenseite ist das Garantieband mit rätschenartigen Zähnen 46 versehen, die mit entsprechenden am unteren Teil des Behälterhalses angebrachten Zähnen 52 im Eingriff sind. Dadurch wird verindert, dass der Verschluss aus seiner Garantielage einfach abgeschraubt werden kann.So that the closure cannot be easily moved from the guarantee position (FIG. 1) to the use position (FIG. 1a), a guarantee band 44 is attached to the intermediate piece and connected to it by a predetermined breaking seam 45. On the inside, the guarantee band is provided with riddle-like teeth 46 which engage with corresponding teeth 52 attached to the lower part of the neck of the container. This prevents the fastener from being easily unscrewed from its guaranteed position.

Am Garantieband ist ein Griffstück 47 angebracht mit dem es vom Zwischenstück abgerissen werden kann. Erst nach dem Abreissen des Garantiebandes kann der Verschluss von der Garantielage weiter bis in die Gebrauchslage geschraubt werden.On the guarantee tape a handle 47 is attached with which it can be torn off the intermediate piece. Only after the guarantee tape has been torn off can the closure of the guarantee position continue to be screwed into the position of use.

Die Figuren 2,2a,2b zeigen einen ähnlichen Verschluss, der sich aber prinzipiell von dem Verschluss nach Figur 1 dadurch unterscheidet, dass er von seiner Garantielage nach Figur 1 in die Gebrauchslage nach Figur 1a durch axiales Aufschieben oder Stossen bringbar ist. Ein weiterer Unterschied besteht darin, dass dabei die Folie 60 von einem hohlen Dorn 201, der in die Ausgussöffnung 202 mündet, durchstossen wird, so dass sie in die in Figur 2a dargestellte Lage 601 gelangt. Das Zwischenstück 40 ist nicht auf dem Behälterhals 501 aufgeschraubt, sondern aufgesprengt. An seiner Aussenseite hat das Zwischenstück kein Gewinde, sondern zwei parallel verlaufende Arretierungsrillen 402, wie in grösserem Masstab in Figur 5 ersichtlich ist. Der Abstand zwischen den Rillen 402 bestimmt den Abstand zwischen der Garantielage und Gebrauchslage. Im Innern des Unterteiles 20 sind Arretierungsnasen 202 angebracht (siehe auch Figur 3), die je nach der Lage des Verschlusses 10,20,30 hinter die obere oder die untere Rille greifen. Damit die Garantielage gesichert ist, ist auch hier ein Garantieband 403 am Zwischenstück 40 angebracht und durch eine Sollbruchnaht 404 damit verbunden. Im Gegensatz zum Garantieband nach Figur 1 ist hier aber keine rätschenartige Drehsicherung mehr erforderlich. Der in der Garantielage befindliche Verschluss kann zwar gedreht aber nicht mehr abgezogen werden. Bei entsprechender Form (wie bei Figur 2) des, an den Behälterhals anschliessenden Teiles des Behälters wird beim Aufschieben in die Gebrauchslage das Garantieband selbsttätig abgesprengt. Stattdessen könnte es auch mit einem Abreissgriff versehen sein.FIGS. 2, 2a, 2b show a similar closure, which differs in principle from the closure according to FIG. 1 in that it can be moved from its guaranteed position according to FIG. 1 to the position of use according to FIG. 1a by being axially pushed on or pushed. Another difference is that the film 60 is pierced by a hollow mandrel 201, which opens into the pouring opening 202, so that it reaches the position 601 shown in FIG. 2a. The intermediate piece 40 is not screwed onto the container neck 501, but is blown open. On the outside, the intermediate piece has no thread, but two parallel locking grooves 402, as can be seen on a larger scale in FIG. 5. The distance between the grooves 402 determines the distance between the guarantee position and the use position. In the interior of the lower part 20 there are locking lugs 202 (see also FIG. 3) which, depending on the position of the closure 10, 20, 30, engage behind the upper or the lower groove. So that the guarantee situation is secured, is also here Guarantee tape 403 attached to the intermediate piece 40 and connected to it by a predetermined breaking seam 404. In contrast to the guarantee tape according to FIG. 1, however, no riddle-like anti-rotation lock is required. The closure in the warranty position can be turned, but can no longer be removed. With a corresponding shape (as in FIG. 2) of the part of the container adjoining the container neck, the guarantee band is automatically blown off when it is pushed into the position of use. Instead, it could also be equipped with a tear-off handle.

Der Verschluss nach Figur 2 kann daher durch Druck in Richtung des Pfeiles A von der Garantielage nach Figur 2 in die Gebrauchslage nach Figur 2a gebracht werden. Hierzu genügt ein Schlag oder Stoss. Dabei platzt das Garantieband 403 von selber ab und die Arretierungsnasen 202 die bisher unter die obere Rille 402 griffen, greifen nun unter die untere Rille 402. Als Anschlag dient der ringförmige Vorsprung 203 an der Unterseite des Unterteiles 20.The closure according to FIG. 2 can therefore be brought from the guarantee position according to FIG. 2 into the use position according to FIG. 2a by pressing in the direction of arrow A. All you need to do is hit or hit. In this case, the guarantee band 403 breaks off by itself and the locking lugs 202, which previously reached under the upper groove 402, now reach under the lower groove 402. The annular projection 203 on the underside of the lower part 20 serves as a stop.

Die Figuren 3-5 zeigen einige weitere Ausführungsvarianten.Figures 3-5 show some other variants.

Figur 3 zeigt unten einen Behälterhals 502 an dem parallel verlaufende Arretierungsringe 503 direkt angeformt sind. Auf den oberen Rand des Halses ist eine Folie 60 angebracht, mit dem der Inhalt des Behältnisses gegen unbefugten Eingriff gesichert ist. Dadurch ist ein gesondertes Zwischenstück überflüssig geworden. Dagegen muss jetzt das Garantieband 204 am Unterteil 20 des Verschlusses angebracht werden. Es ist durch die Sollbruchnaht 205 mit dem unteren Rand des Unterteiles 20 verbunden. Ansonsten entspricht die Anordnung und die Wirkungsweise dem anhand der Figuren 2,2a,2b beschriebenen.Figure 3 shows below a container neck 502 on which parallel locking rings 503 are directly molded. A film 60 is attached to the upper edge of the neck, with which the contents of the container are secured against unauthorized intervention. As a result, a separate intermediate piece has become unnecessary. In contrast, the guarantee band 204 must now be attached to the lower part 20 of the closure. It is connected to the lower edge of the lower part 20 by the predetermined breaking seam 205. Otherwise, the arrangement and the mode of operation correspond to that described with reference to FIGS. 2,2a, 2b.

Figur 4 zeigt einen aufschraubbaren Verschluss. Der Behälterhals weist ein Aussengewinde 504 und eine daran anschliessende Rätschenverzahnung 505 auf. Der obere Rand des Halses ist mit einer aufgeklebten oder aufgeschweissten Membran 60 versehen. Der untere Rand des Unterteiles 20 ist mit einem Garantieband 204 mit Abreisslasche 206 versehen.Figure 4 shows a screw-on closure. The container neck has an external thread 504 and an adjoining ratchet toothing 505. The upper edge of the neck is provided with a glued or welded membrane 60. The lower edge of the lower part 20 is provided with a guarantee tape 204 with a tear-off tab 206.

Der Unterteil 20 des Verschlusses ist mit einem, dem Gewinde 504 am Behältnis entsprechenden Innengewinde 207 versehen. An der unteren, dem Behälterhals zugewendeten Seite des Unterteiles 20 ist eine Schneidspitze 208 angebracht, die in eine Auflaufkante 209 übergeht, die wie eine Pflugschar wirkt. Beim Aufschrauben (nach dem Entfernen des Garantiebandes) in die Gebrauchslage schneidet zuerst die Spitze 208, nach dem Erreichen einer gewissen Tiefe schneidet der Zahn nicht mehr und die Auflaufkante 209 drückt die teilweise ringförmig aufgeschnittene Membran 60 nach innen. Es besteht aber keine Gefahr, dass ein loser Teil der Folie in den Behälter gelangt.The lower part 20 of the closure is provided with an internal thread 207 corresponding to the thread 504 on the container. On the lower side of the lower part 20 facing the container neck, a cutting tip 208 is attached, which merges into a leading edge 209, which acts like a ploughshare. When screwing (after removing the guarantee tape) into the position of use, the tip 208 first cuts, after reaching a certain depth the tooth no longer cuts and the leading edge 209 presses the partially annularly cut membrane 60 inwards. However, there is no risk that a loose part of the film will get into the container.

Figur 5 zeigt ein Zwischenstück 400, das bei entsprechender Dimensionierung das Zwischenstück 40 nach Figur 2 ersetzen könnte. Es unterscheidet sich aber von diesem dadurch, dass als Ersatz für eine gesonderte Folie hier der obere Teil des Zwischenstückes so dünn ausgebildet ist, dass es eine durchstechbare Membran 405 bildet. Zusätzlich ist diese Membran noch mit sternförmig angeordneten Schwächungslinien 406 versehen. Für ein sicherers Aufsprengen auf den Behälterhals ist das Zwischenstück mit einer Ringwulst 506 versehen und die Innenwand des Zwischenstücks 400 weist eine Ringwulst 407 auf.FIG. 5 shows an intermediate piece 400 which, with appropriate dimensioning, could replace the intermediate piece 40 according to FIG. 2. However, it differs from this in that, as a replacement for a separate film, the upper part of the intermediate piece is so thin that it forms a pierceable membrane 405. In addition, this membrane is also provided with lines of weakness 406 arranged in a star shape. For a more secure blasting on the neck of the container, this is Intermediate piece provided with an annular bead 506 and the inner wall of the intermediate piece 400 has an annular bead 407.

Der Uebersichtlichkeit halber sind in der Zeichnung diejenigen Sicherungsmittel weggelassen, welche ein Oeffnen der Kappe 1 beziehungsweise 10 verhindern solange sich der Verschluss in der Garantielage befindet. Ohne derartige Sicherungsmittel könnte man die Kappe öffnen und die Folie oder Membran durch die Ausgussöffnung hindurch aufstechen!For the sake of clarity, those securing means which prevent opening of the cap 1 or 10 as long as the closure is in the guarantee position are omitted in the drawing. Without such securing means, the cap could be opened and the film or membrane pierced through the pouring opening!

Ein solches Sicherungsmittel könnte die Form eines zusätzlichen Garantiebandes haben, was aber umständlich wäre. Die schweizerische Pantentschrift No. ........ (Gesuch No ........) gibt eine Lösung für dieses Problem an, indem an der Kappe ein Haken angeformt ist der die Kappe in Garantielage verriegelt und sich selbsttätig vom Unterteil löst, wenn der Verschluss in die Gebrauchslage gebracht wird!Such a safeguard could take the form of an additional guarantee band, which would be cumbersome. The Swiss pantograph No. ........ (Request No ........) provides a solution to this problem by forming a hook on the cap that locks the cap in the guaranteed position and automatically detaches itself from the lower part if the closure is brought into the position of use!
