The closure consists of the base part (11) and the lid (13) having two rotary pins (15). In the closed state, the pin (20) closes the delivery opening (18). A locking member (23) is constructed on the lid (13) which can only be opened when the locking member (23) has been removed. The locking member (23) has a dual function. It also serves for piercing a closure film on the bottle. For this purpose, the locking member (37) is pressed into the spout (39) and then removed again. <IMAGE>

Description

Die Erfindung betrifft einen Verschluss für Behälter, insbesondere für Flaschen, mit einem Basisteil, welcher mindestens eine Ausgabeöffnung aufweist und auf den Behälter aufgesetzt werden kann, einem Deckel, welcher mit dem Basisteil gelenkig verbunden ist, um die Ausgabeöffnung freizugeben oder zu verschliessen,und einem wegnehmbaren Sperrglied zur Verhinderung und/oder Anzeige einer unbefugten Oeffnung des Verschlusses. Ein Verschluss dieser Art ist beispielsweise in der EP-A-0151242 dargestellt. Er weist einen Basisteil und einen Deckel auf, die mit einem Filmscharnier miteinander verbunden sind. An der Peripherie des Basisteils befindet sich ein aus einem Stück mit dem Basisteil bestehender Kunststoffstreifen. Dieser Kunststoffstreifen weist in Abständen voneinander kleindimensionierte Verbindungsstellen mit dem Basisteil auf. Zwischen dem Basisteil und dem Kunststoffstreifen besteht daher eine Vielzahl von Schlitzen, in welche nach dem ersten Schliessen des Deckels entsprechende Zähne des Deckels eingreifen, so dass dieser nicht mehr geöffnet werden kann, ohne dass der Kunststoffstreifen abgerissen wird. Das Abreissen lässt sich sehr leicht bewerkstelligen, indem man ein loses Ende des Kunststoffstreifens ergreift und wegreisst. Beim Wegreissen werden die Verbindungsstellen nacheinander zerstört, ohne dass hiefür ein grosser Kraftaufwand notwendig wäre. Nach dem Wegreissen des Kunststoffstreifens kann der Deckel mit Leichtigkeit geöffnet werden. Wenn der Käufer eine Flasche im Laden kauft, so zeigt der intakte Verschluss an, dass sich die Flasche im Originalzustand befindet, also nicht geöffnet wurde. Der Verschluss erfüllt somit eine Garantie-Funktion.The invention relates to a closure for containers, in particular for bottles, with a base part which has at least one dispensing opening and can be placed on the container, a lid which is articulated to the base part in order to open or close the dispensing opening, and a removable locking member to prevent and / or display an unauthorized opening of the closure. A closure of this type is shown, for example, in EP-A-0151242. It has a base part and a lid, which are connected to one another with a film hinge. At the periphery of the base part there is a plastic strip consisting of one piece with the base part. This plastic strip has small-sized connection points with the base part at intervals. There is therefore a large number of slots between the base part and the plastic strip, into which corresponding teeth of the cover engage after the cover has been closed for the first time, so that it can no longer be opened without the plastic strip being torn off. Tearing off is very easy to do by grasping a loose end of the plastic strip and tearing it away. If they are torn away, the connection points are destroyed one after the other without great effort being required. After tearing off the plastic strip, the lid can be opened with ease. When the buyer buys a bottle in the store, the intact closure indicates that the bottle is in its original condition, i.e. not opened. The closure therefore fulfills a guarantee function.

Der vorbekannte Verschluss hat den Nachteil, dass er relativ kompliziert ist und zu seiner Herstellung teure Werkzeuge erfordert. Da er aus einem einzigen Teil besteht, kann er lediglich einfarbig ausgeführt werden. Das Filmscharnier mit Kunststoffeder kann beim Oeffnen oder Schliessen zu einer raschen Deckelbewegung führen, bei der die Gefahr besteht, dass Tropfen vom Flascheninhalt, z.B. Ketchup, wegfliegen.The known closure has the disadvantage that it is relatively complicated and requires expensive tools to manufacture it. Since it consists of a single part, it can only be made in one color. The film hinge with plastic leather can lead to a rapid lid movement when opening or closing, with the risk of that drops of the bottle contents, e.g. ketchup, fly away.

Es ist Aufgabe der vorliegenden Erfindung, einen verbesserten Verschluss der eingangs erwähnten Art zu schaffen, welcher mindestens einen Teil dieser Nachteile vermeidet.It is an object of the present invention to provide an improved closure of the type mentioned at the outset which avoids at least some of these disadvantages.

Erfindungsgemäss wird dies dadurch erreicht, dass der Deckel als zweiarmiger Hebel ausgebildet ist, und dass das Sperrglied zwischen einem Arm des Hebels und dem Basisteil angeordnet ist, um ein Oeffnen des Deckels ohne vorherige Entfernung des Sperrglieds zu verhindern. Im Gegensatz zum bekannten Stand der Technik besteht beim Versuch,den Deckel vor der Entfernung des Sperrgliedes zu öffnen, keine Gefahr, dass das Sperrglied entfernt wird. Beim Oeffnen wird nämlich das Sperrglied auf Druck beansprucht. Zweckmässigerweise stellt das Sperrglied einen wegbrechbaren Teil des Deckels oder des Basisteils dar. Ein fehlendes Sperrglied an einem Verschluss zeigt an, dass der Verschluss bereits einmal geöffnet wurde. Das Sperrglied hat somit Garantiefunktion. Das wegbrechbare Sperrglied kann entweder zusammen mit dem Deckel oder zusammen mit dem Basisteil hergestellt werden. In der Regel ist die Herstellung zusammen mit dem Deckel einfacher. Die Verbindung des Sperrgliedes mit dem Deckel oder dem Basisteil erfolgt vorteilhaft durch dünne Verbindungsstege, die ohne grossen Kraftaufwand brechen, so dass das Sperrglied leicht weggebrochen werden kann. Wird ohne vorheriges Wegbrechen der Versuch unternommen, den Verschluss zu öffnen, so gelingt dies nicht. Da bei einem solchen Oeffnungsversuch das Sperrglied auf Druck beansprucht wird, treten an den Verbindungsstegen keine Zug- oder Scherkräfte auf. Sie bleiben daher intakt. Dies stellt eine gewisse Kindersicherung dar. Andererseits ist es möglich, die Verbindungsstege sehr schwach auszugestalten, was das gewollte Entfernen des Sperrglieds erleichtert.According to the invention, this is achieved in that the cover is designed as a two-armed lever and in that the locking member is arranged between an arm of the lever and the base part in order to prevent the lid from being opened without first removing the locking member. In contrast to the known prior art, when attempting to open the lid before removing the locking member, there is no danger that the locking member will be removed. When opening, the locking member is stressed under pressure. The locking member expediently constitutes a break-away part of the cover or the base part. A missing locking member on a lock indicates that the lock has already been opened once. The blocking element thus has a guarantee function. The breakable locking member can be made either together with the lid or together with the base part. As a rule, it is easier to manufacture together with the lid. The connection of the locking member to the lid or the base part is advantageously carried out by thin connecting webs that break without great effort, so that the locking member can be easily broken away. If an attempt is made to open the closure without breaking away beforehand, this will not succeed. Since the locking member is subjected to pressure during such an opening attempt, no tensile or shear forces occur at the connecting webs. Therefore, they remain intact. This represents a certain amount of child safety. On the other hand, it is possible to make the connecting webs very weak, which facilitates the deliberate removal of the locking member.

Vorteilhaft stellen Deckel und Basisteil separate Teile dar. Dies ermöglicht es, den Verschluss mit zwei relativ einfachen Formen herzustellen. Diese Formen können dann auch leicht als Mehrfachformen ausgeführt werden. Da ferner bei der Herstellung als separate Teile kein Filmscharnier zwischen Basisteil und Deckel notwendig ist, kann der Verschluss aus einem relativ billigen Kunststoff gefertigt werden, ohne dass die Gefahr besteht, dass ein Filmscharnier bricht. Die Verwendung von Mehrfachformen ermöglicht auch eine hohe Produktionskapazität. Von besonderem Vorteil ist die Möglichkeit der verschiedenen Farbgebung von Basisteil und Deckel. Wenn der Deckel eine Beschriftung trägt, kann auch die Beschriftung ohne grösseren Aufwand geändert werden. Diese Vorteile wiegen den Nachteil auf, dass der Verschluss aus zwei Teilen zusammengesetzt werden muss. Auch bei einem einstückigen Verschluss muss nach der Herstellung der Deckel in den Basisteil eingedrückt werden, was einen ähnlichen Arbeitsgang erfordert wie das Zusammensetzen des Verschlusses aus zwei Teilen. Wenn auch ein zweiteiliger Verschluss einem einstückigen Verschluss vorgezogen wird, kann doch festgestellt werden, dass die vorliegende Erfindung auch als einstückiger Verschluss realisierbar ist.The lid and base part are advantageously separate parts. This makes it possible to produce the closure with two relatively simple shapes. These shapes can then easily be designed as multiple shapes. Since also in the manufacture since separate parts do not require a film hinge between the base part and the lid, the closure can be made from a relatively cheap plastic without the risk of a film hinge breaking. The use of multiple molds also enables a high production capacity. The possibility of different colors for the base part and lid is particularly advantageous. If the lid has a label, the label can also be changed without much effort. These advantages outweigh the disadvantage that the closure has to be composed of two parts. Even in the case of a one-piece closure, the cover must be pressed into the base part after manufacture, which requires a similar process to assembling the closure from two parts. Even if a two-part closure is preferred to a one-piece closure, it can nevertheless be established that the present invention can also be implemented as a one-piece closure.

Zweckmässigerweise ist das Sperrglied als Werkzeug zum Durchstechen einer Verschlussfolie des Behälters ausgebildet. Es kann zu diesem Zwecke eine Spitze aufweisen. Vorteilhaft ist am Sperrglied auch ein Vorsprung vorgesehen,welcher die Stechbewegung begrenzt und damit verhindert, dass das Sperrglied in den Behälter gelangt. Der Vorsprung am Sperrglied erleichtert auch das Wegbrechen des Sperrglieds vom Deckel oder vom Basisteil.The locking member is expediently designed as a tool for piercing a closure film of the container. It may have a tip for this purpose. A protrusion is also advantageously provided on the locking member, which limits the lancing movement and thus prevents the locking member from getting into the container. The projection on the locking member also facilitates the breaking away of the locking member from the cover or from the base part.

Eine vorteilhafte Ausführungsform der Erfindung sieht vor, dass der Deckel in einer Nut des Basisteils angeordnet ist. Dies ergibt eine formschöne Konstruktion und bildet auch einen Schutz des Deckels beim Transport des Behälters. Der Deckel ist zweckmässigerweise von oben betrachtet ungefähr rechteckförmig und weist im Querschnitt ein etwa U-förmiges Profil auf. Dies ergibt eine einfache Ausbildung des Deckels, wobei trotz geringem Materialbedarf eine relativ grosse Festigkeit erzielt wird.An advantageous embodiment of the invention provides that the cover is arranged in a groove in the base part. This results in an elegant design and also protects the lid when the container is being transported. The lid is expediently approximately rectangular when viewed from above and has an approximately U-shaped profile in cross section. This results in a simple design of the cover, a relatively high strength being achieved despite the low material requirement.

Ein Ausführungsbeispiel der Erfindung wird nun unter Bezugnahme auf die Zeichnung beschrieben. Es zeigt:

Der in den Figuren 1 bis 4 dargestellte Verschluss besteht aus einem Basisteil 11 und einem Deckel 13, die gelenkig miteinander verbunden sind. Diese gelenkige Verbindung wird durch zwei Drehzapfen 15 des Deckels 13 bewerkstelligt, die in entsprechende Lager im Basisteil 11 eingreifen. Basisteil 11 und Deckel 13 sind Spritzteile aus Kunststoff. Sie können verschiedene Farben aufweisen und auch aus verschiedenen Materialien bestehen. Als Kunststoffmaterial eignet sich beispielsweise Polypropylen, Polystyrol, Polikarbonat, Polyäthylen.The closure shown in Figures 1 to 4 consists of a base part 11 and a lid 13 which are hinged together. This articulated connection is brought about by two pivot pins 15 of the cover 13, which engage in corresponding bearings in the base part 11. Base part 11 and cover 13 are molded parts made of plastic. You can have different colors have and also consist of different materials. Polypropylene, polystyrene, polycarbonate, polyethylene, for example, are suitable as the plastic material.

Am Basisteil 11 ist ein Stutzen 17 ausgebildet, der in bekannter Weise so ausgestaltet ist, dass eine feste Verbindung mit dem Behälter, z.B. einer Flasche 16, erzielt wird, wo der Verschluss Verwendung findet. Der Basisteil weist ferner einen Kragen 19 auf, dessen Formgebung auf jene der Flasche 16 abgestimmt ist.On the base part 11, a nozzle 17 is formed, which is designed in a known manner so that a fixed connection to the container, e.g. a bottle 16, is achieved where the closure is used. The base part also has a collar 19, the shape of which is matched to that of the bottle 16.

Wie Figur 2 zeigt, ist ein längliches Sperrglied 23 mit dünnen Stegen 25 mit dem Deckel 13 verbunden. Das Sperrglied kann daher leicht abgetrennt werden. Die Abtrennung wird noch durch einen seitlichen Vorsprung 27, an welchem man mit dem Finger angreifen kann, erleichtert.As FIG. 2 shows, an elongate locking member 23 with thin webs 25 is connected to the cover 13. The locking member can therefore be easily removed. The separation is further facilitated by a lateral projection 27 on which one can grip with the finger.

Von Bedeutung ist nun, dass der Deckel 13 als zweiarmiger Hebel ausgebildet ist. Im nichtabgetrennten Zustand verhindert das am kürzeren Arm 21 des Hebels angeordnete Sperrglied 23 ein Oeffnen des Deckels 13. Wird nämlich an der Nase 29 eine Kraft nach oben ausgeübt, so wird das Oeffnen des Deckels 13 durch das Sperrglied 23 verhindert, weil es zwischen dem Hebelarm 21 und dem Grund 31 der Nute 33 im Basisteil 11 eingeklemmt bleibt. Erst nach dem Wegbrechen des Sperrteils 23 kann der Deckel 13 um die Zapfen 15 gedreht werden, wie dies in Figur 4 dargestellt wird.It is important that the cover 13 is designed as a two-armed lever. In the non-disconnected state, the locking member 23 arranged on the shorter arm 21 of the lever prevents opening of the lid 13. If an upward force is exerted on the nose 29, the opening of the lid 13 is prevented by the locking member 23 because it is between the lever arm 21 and the bottom 31 of the groove 33 remains clamped in the base part 11. Only after the blocking part 23 has broken away can the cover 13 be rotated around the pins 15, as is shown in FIG.

Wie Figur 3 zeigt, ist der Deckel 13 von oben betrachtet etwa rechteckförmig. Aus Figur 2 ist weiter ersichtlich, dass der Deckel 13 im Querschnitt ein etwa U-förmiges Profil aufweist. Es sind aber auch andere Formgebungen des Deckels möglich.As shown in FIG. 3, the cover 13 is approximately rectangular when viewed from above. From Figure 2 it can also be seen that the cover 13 has an approximately U-shaped profile in cross section. However, other shapes of the cover are also possible.

Figur 4 zeigt die Verwendung des Sperrglieds als Werkzeug zum Durchstechen einer Verschlussfolie 34 des Behälters 16. Zu diesem Zweck weist das Sperrglied 23 eine Spitze 35 auf. Der Vorsprung 27 dient als Begrenzung.FIG. 4 shows the use of the locking member as a tool for piercing a closure film 34 of the container 16. For this purpose, the locking member 23 has a tip 35. The projection 27 serves as a limitation.

Der hintere Teil 37 des Sperrgliedes ist geriffelt, um die Handhabung zu erleichtern. Die Ausgabeöffnung 18 wird durch das Ende eines rohrförmigen Ausgusses 39 gebildet, der zugleich als Führung des Sperrgliedes 23 beim Durchstechen der Verschlussfolie 34 dient (Fig. 4). Bei geschlossenem Deckel 13 wird die Ausgabeöffnung 18 durch den Zapfen 20 des Deckels verschlossen (Fig. 1).The rear part 37 of the locking member is corrugated to facilitate handling. The dispensing opening 18 is formed by the end of a tubular spout 39, which also serves as a guide for the locking member 23 when the closure film 34 is pierced (FIG. 4). When the lid 13 is closed, the dispensing opening 18 is closed by the pin 20 of the lid (FIG. 1).

Wie die Fig. 5 zeigt, kann das Sperrglied 23 auch eine andere Formgebung besitzen als in Fig. 2. Das Sperrglied 23 von Fig. 5 ist aber wiederum mit Stegen 25 am Deckel 13 befestigt. Es erstreckt sich seitlich über den Deckel 13 hinaus, so dass es der Käufter leicht als wegbrechbares Glied erkennt und abtrennen kann. Wie Fig. 6 zeigt, kann ein Werkzeug 23′ lose oder wegbrechbar unter dem Deckel 3 angeordnet sein und zum Durchstechen einer Verschlussfolie verwendet werden (Fig. 7), indem es in den Ausguss 39 gesteckt wird.As shown in FIG. 5, the locking member 23 can also have a different shape than in FIG. 2. The locking member 23 of FIG. 5 is in turn fastened to the cover 13 with webs 25. It extends laterally beyond the lid 13, so that the buyer can easily recognize it and break it off as a breakable member. As shown in Fig. 6, a tool 23 'can be arranged loosely or breakaway under the lid 3 and used to pierce a sealing film (Fig. 7) by inserting it into the spout 39.

Es sind verschiedene Aenderungen möglich, ohne vom Gedanken der Erfindung abzuweichen. So kann z.B. das Sperrglied 23 oder Werkzeug 23′ auch am Basisteil 11 ausgebildet werden. Es kann z.B. durch Eindrückzapfen 42 wegbrechbar am Basisteil 11 oder Deckel 13 befestigt sein (Fig. 8).Various changes are possible without departing from the spirit of the invention. For example, the locking member 23 or tool 23 'are also formed on the base part 11. For example, can be attached to base part 11 or cover 13 in a break-away manner by push-in pin 42 (FIG. 8).
