Description

Verschluss für Getränkebehälter Closure for beverage containers
[0001] Die Erfindung betrifft einen Verschluss für Getränkebehälter mit einem im Wesentlichen zylindrischen Hals mit endseitiger Öffnung und einer Verschlusskappe.The invention relates to a closure for beverage containers having a substantially cylindrical neck with end-side opening and a closure cap.
[0002] Getränkebehälter mit gattungsbildenden Verschlüssen sind in unterschiedlicher Ausgestaltung bekannt. Diese sind insbesondere als Keg-Fässer weit verbreitet. Dabei handelt es sich um Getränkefässer meist aus Metall und ggf. mit Gummiummantelung in unterschiedlichen Größen. Die Fässer weisen am oberen Ende einen im Wesentlichen zylindrischen Hals auf mit einer endseitigen Öffnung. Diese Öffnung wird mit einer Verschlusskappe verschlossen. Diese Kappe weist üblicherweise ein Ventil und einen Anschluss für ein Kupplungselement zu einer Zapfanlage oder dgl. auf. Das Ventil ist mit einem innen im Fass liegenden Rohr verbunden, das bis in den Bodenbereich des Fasses reicht und über das der Fassinhalt zum Ventil hinaufgedrückt wird, wenn ein Überdruck im Inneren des Fasses erzeugt wird.Beverage containers with generic fasteners are known in different configurations. These are especially common as keg barrels. These are mostly beverage barrels made of metal and possibly with rubber sheath in different sizes. The barrels have at the upper end a substantially cylindrical neck with an end-side opening. This opening is closed with a cap. This cap usually has a valve and a connection for a coupling element to a dispenser or the like. On. The valve is connected to a tube located inside the barrel, which extends into the bottom of the barrel and over which the contents of the barrel are pushed up to the valve when an overpressure is created inside the barrel.
[0003] Für die Verbindung der Verschlusskappe mit dem Hals sind eine Reihe von verschiedenen Systemen bekannt. Die WO 2007/064277 A1 zeigt beispielsweise eine Anordnung, bei der die Verschlusskappe außenseitig den Hals übergreift und dort über eine formschlüssige Anordnung von umlaufenden Nuten und kor- respondierenden Kragen eine Verrastung der Verschlusskappe mit dem Fasshals ermöglicht. Weiterhin weist der Hals einen umlaufenden Ring unterhalb der Verschlusskappe auf, der zur Stabilisierung und Handhabung des Fasses notwendig ist.For the connection of the cap with the neck a number of different systems are known. For example, WO 2007/064277 A1 shows an arrangement in which the closure cap engages over the neck on the outside and makes it possible to lock the closure cap to the neck of the neck via a form-fitting arrangement of circumferential grooves and corresponding collar. Furthermore, the neck has a circumferential ring below the cap, which is necessary for the stabilization and handling of the barrel.
[0004] Weitere Fassverschlüsse sind beispielsweise in der DE 101 38 365 A1 , der EP 0 915 283 B1 oder der DE 36 08 300 A1 bekannt.Further barrel closures are known, for example, in DE 101 38 365 A1, EP 0 915 283 B1 or DE 36 08 300 A1.
[0005] Die erfindungsgemäßen Behälterverschlüsse weisen allerdings eine Reihe von Nachteilen auf. Insbesondere sind sie aufwändig und teuer, schwierig zu reinigen und müssen aus Stabilitätsgründen Versteifungen im Halsbereich haben, um die teilweise hohen mechanischen und insbesondere die Druckbelastungen im Inneren des Fasses aufnehmen zu können.The container closures according to the invention, however, have a number of disadvantages. In particular, they are complex and expensive, difficult to clean and must have reasons of stability stiffeners in the neck area to the sometimes high mechanical and in particular the pressure loads in the neck Inside of the barrel to be able to record.
[0006] Die Erfindung soll demgegenüber eine deutliche Vereinfachung der Verschlussgestaltung ermöglichen und so bei gleichbleibender oder sogar erhöhter Stabilität der Halsanordnung einen einfachen und sicheren Verschluss des Fasses erlauben.In contrast, the invention should allow a significant simplification of the closure design and thus allow a constant and even increased stability of the neck assembly a simple and secure closure of the barrel.
[0007] Die Erfindung erreicht dies durch einen Verschluss für Getränkebehälter mit den Merkmalen des Patentanspruches 1.The invention achieves this through a closure for beverage containers with the features of claim 1.
[0008] Der innenliegende Rastkragen wirkt mit der am Außenumfang des im Wesentlichen ringförmigen Einsteckschaftes befindli-chen Rastnut derartig zusammen, dass nach dem Einstecken der Verschlusskappe die Rastnut durch die sich verjüngende Profilierung über den Rastkragen geschoben werden kann und nach dem Eindrücken diesen unterseitig übergreift, so dass eine umlaufende Verrastung der Rastnut mit der in Einsteckrichtung liegenden Ringfläche des Rastkragens entsteht und so eine sichere Haltung der Verschlusskappe gewährleistet ist. Die Profilierung der Rastnut ist dabei in Einsteckrichtung spitz zulaufend ausgebildet, so dass ein einfaches Einstecken der Kappe möglich ist. Die Dimensionierung der wirksamen Tiefen von Rastkragen und korrespondierender Rastnut sind so ausgebildet, dass ein sicherer Halt der Verschlusskappe gewährleistet ist.The inner locking collar interacts with the locking groove located on the outer circumference of the substantially annular insertion shaft in such a way that, after inserting the locking cap, the locking groove can be pushed over the locking collar by the tapered profiling and, after pressing in, overlaps it on the underside, so that a circumferential latching of the detent groove with the insertion surface in the direction of the annular surface of the detent collar is formed, thus ensuring a secure position of the closure cap. The profiling of the locking groove is tapered in the insertion direction, so that a simple insertion of the cap is possible. The dimensioning of the effective depths of the detent collar and the corresponding detent groove are designed so that a secure hold of the closure cap is ensured.
[0009] So wird erreicht, dass die komplette, für die Haltung der Kappe nötigeIt is thus achieved that the complete, necessary for the attitude of the cap
Formflächengestaltung im Inneren des Halses liegt, was für den Außenhalsbereich weitestmögliche Gestaltungsmöglichkeiten offen lässt bei gleichzeitig mindestens gleichbleibender bzw. erhöhter Stabilität der Gesamtanordnung.Form surface design is located inside the neck, which leaves open the widest possible design options for the outer neck area at the same time at least constant or increased stability of the overall arrangement.
[0010] Diese erfindungsgemäße Behältergestaltung, bietet daher eine Reihe von Vorteilen gegenüber den bekannten Behältergestaltungen. Insbesondere kann die Außenseite des Behälterhalses vielfältige Ausgestaltungen annehmen, abhängig von dem gewünschten Einsatzzweck. Sie kann beispielsweise vollkommen glatt sein, einen umlaufenden Ring aufweisen zur Kompatibilität mit vorhandenen Anlagen oder auch eine umlaufende Nut aufweisen, so dass eine besonders kompakte und trotzdem sicher greifbare Behältergestaltung entsteht. Gleichzeitig ist durch die innen liegende Verrastung des Behälters mit der Verschlusskappe eine sichere Verbindung der beiden Elemente ermöglicht, die den Behälterinhalt sicher vor Umgebungsein- flüssen schützt und eine hohe Druckbeständigkeit und dgl. aufweist. Ausgestaltungen der Erfindung ergeben sich aus den Unteransprüchen.This container design according to the invention, therefore, offers a number of advantages over the known container designs. In particular, the outside of the container neck can take on a variety of configurations, depending on the desired application. For example, it can be completely smooth, have a circumferential ring for compatibility with existing equipment or also have a circumferential groove, so that a particularly compact, yet secure tangible container design arises. At the same time, the internal latching of the container with the closure cap enables a secure connection of the two elements, which reliably protects the container contents from environmental influences and has high pressure resistance and the like. Embodiments of the invention will become apparent from the dependent claims.
[0011] Vorgesehen kann sein, dass die Verschlusskappe einen umlaufenden, den Hals außenseitig übergreifenden Stütz- und/oder Führungsring aufweist.Provided may be that the closure cap has a circumferential, the neck on the outside cross-spanning support and / or guide ring.
[0012] Dieser Ring ist so gestaltet, dass er die Halsöffnung außenseitig übergreift und so einerseits eine genaue Führung der Kappe bei dem Aufsetzen ermöglicht und andererseits eine Kraftübertragung von dem innen liegenden Einsteckschaft über die Verschlusskappenoberseite auf die Außenseite des Halses ermöglicht, so dass eine verbesserte Stabilität und Halteeigenschaften der Kappenanordnung entsteht.This ring is designed so that it engages over the neck opening on the outside and so on the one hand allows an accurate guidance of the cap during placement and on the other hand enables a power transmission from the inner insertion shaft on the cap top to the outside of the neck, so that an improved Stability and holding properties of the cap assembly arises.
[0013] Vorgesehen kann sein, dass auf der der öffnungsseitigen Ringfläche des Rastkragens eine Dichtung vorgesehen ist.It can be provided that on the opening-side annular surface of the locking collar, a seal is provided.
[0014] Ein oben liegender umlaufender Dichtungsring stellt so eine vorteilhafte Möglichkeit der Abdichtung des Getränkebehälters gegen die Umgebung dar, da die Verschlusskappe nach dem Aufsetzen gegen die Dichtung gedrückt wird und sich an der unteren Ringfläche des Rastkragens verrastet, so dass eine sichere Quetschkraft auf die Dichtung wirkt und für eine gute Dichtwirkung sorgt.An overhead circumferential sealing ring thus provides an advantageous way of sealing the beverage container against the environment, since the cap is pressed after placement against the seal and locked to the lower annular surface of the detent collar, so that a secure squeezing force on the Seal acts and ensures a good sealing effect.
[0015] Vorgesehen kann ebenfalls sein, dass auf der Außenfläche des Einsteckschaftes eine Dichtung vorgesehen ist.It can also be provided that a seal is provided on the outer surface of the insertion shaft.
[0016] Durch die entsprechende Dimensionierung der einzelnen Teile, insbesondere des Dichtungsringes, kann auch zwischen der innen liegenden Fläche des Rastkragens und der Außenfläche des Einsteckschaftes eine gute Dichtwirkung durch eine dazwischen liegende Dichtung erzielt werden. [0017] In Ausgestaltung ist vorgesehen, dass der Hals einen außen-seitig umlaufenden Stützring aufweist.By appropriate dimensioning of the individual parts, in particular of the sealing ring, a good sealing effect can be achieved by an intermediate seal between the inner surface of the detent collar and the outer surface of the Einsteckschaftes. In an embodiment, it is provided that the neck has an outer side circumferential support ring.
[0018] Derartige Stützringe, auch Neckringe genannt, sind bei bestimmten Fassbzw. Keg-Versionen bekannt. Dort dienen sie allerdings insbesondere der Stabilisierung der Gesamtanordnung. Gerade dies ist bei der erfindungsgemäßen Halsgestaltung nicht mehr nötig. Trotzdem kann ein entsprechender Ring an der Außenseite vorgesehen sein, wobei dieser dann im Wesentlichen der Kompatibilität mit vorhandenen Abfüll- oder Zapfanlagen dient und für die eigentliche Stabilität und Funktion des Behäiterverschiusses nicht mehr notwendig ist.Such support rings, also called neck rings, are certain Fassbzw. Keg versions known. There, however, they serve in particular to stabilize the overall arrangement. This is no longer necessary with the neck design according to the invention. Nevertheless, a corresponding ring may be provided on the outside, which then essentially serves the compatibility with existing filling or dispensing equipment and is no longer necessary for the actual stability and function of the Behäiterverschiusses.
[0019] Vorgesehen kann daher ebenfalls sein, dass der Hals eine außenseitig umlaufende Halte- und/oder Führungsnut aufweist.Provided may therefore also be that the neck has an outside circumferential holding and / or guide groove.
[0020] Auch eine derartige Nut bietet sich als Möglichkeit zur maschinellen Getränkebehälterhandhabung an. Auch an einer solchen Nut kann der Behälter sicher ergriffen und durch die für die Abfüllung und dgl. benötigten Anlagen transportiert werden. Da, wie ausgeführt, durch die erfindungsgemäße Halsgestaltung an der Außenseite keine Stabilitätserhöhenden Maßnahmen mehr nötig sind, kann auch über die Nut eine ähnliche Funktionalität erreicht werden.Such a groove offers itself as a possibility for machine beverage container handling. Even at such a groove, the container can be taken safely and transported by the required for bottling and the like. Equipment. Since, as stated, by the neck design according to the invention on the outside of any stability-enhancing measures are no longer necessary, a similar functionality can be achieved via the groove.
[0021] Vorteilhaft kann sein, dass der Hals einen innenseitig umlaufenden Stützring aufweist.It may be advantageous that the neck has an inside circumferential support ring.
[0022] Über einen derartigen Stützring lässt sich die Gesamtanordnung weiter stabilisieren, insbesondere gegenüber mechanischen Belastungen von außen und gegenüber einem Überdruck im Inneren.About such a support ring, the overall arrangement can be further stabilized, especially against mechanical loads from the outside and against an overpressure in the interior.
[0023] Dabei kann es vorteilhaft sein, dass der innenseitig umlaufende Stützring derartig ausgebildet ist, dass sich die Rastnut bei Verformung der Verschlusskappe mit dem Stützring verklemmt.It may be advantageous that the inside circumferential support ring is formed such that the locking groove jammed in deformation of the cap with the support ring.
[0024] In einer derartigen Gestaltung sitzt der Stützring unterhalb des umlaufenden Rastkragens in einem Abstand, der für ein sicheres Eintreten und Verrasten der Rastnut mit der unteren Ringfläche des Rastkragens nötig ist. Weiterhin ist der Abstand so gewählt, dass sich bei einer Verformung der Verschlusskappe die entsprechende Aufbiegung übertragen durchIn such a configuration, the support ring sits below the circumferential detent collar at a distance for a safe entry and locking the Locking groove with the lower annular surface of the locking collar is necessary. Furthermore, the distance is selected so that transmitted in a deformation of the cap, the corresponding bend through
[0025] den Einsteckschaft so auf die Rastnut auswirkt, dass diese unten mit dem Stützring in Kontakt kommt und so eine Verklemmwirkung entsteht, die die Stabilität zusätzlich erhöht.The Einsteckschaft so affects the locking groove, that this comes down with the support ring in contact and thus a Verklemmwirkung arises, which additionally increases the stability.
[0026] Weitere Vorteile und Merkmale der Erfindung ergeben sich aus den Zeichnungen. Diese zeigen inFurther advantages and features of the invention will become apparent from the drawings. These show in

Die Rastnut 6 ist so ausgebildet, dass sie nach dem Einstecken die in Einsteckrichtung liegende Ringfläche 7 des Rastkragens 4 übergreift. Auf der gegenüberliegenden Ringfläche 8 des Rastkragens 4 ist eine Ringdichtung 9 angeordnet. Zusätzlich ist am Hals ein außenseitig umlaufender Stützring 10 zum sicheren Ergreifen des Getränkebehälters 1 mit bekannten Anlagen vorgesehen.[0028] FIG. 3 has an insertion shaft 5, at the end remote from the cap 3, a peripheral locking groove 6 is arranged, which in the insertion direction Bevelled is profiled, so that easy insertion is possible. The locking groove 6 is formed so that it engages after insertion in the insertion direction lying annular surface 7 of the locking collar 4. On the opposite annular surface 8 of the locking collar 4, a ring seal 9 is arranged. In addition, an outside circumferential support ring 10 is provided for securely gripping the beverage container 1 with known systems at the neck.
[0029] Bei der in Fig. 2 dargestellten Variante des erfindungsgemäßen Verschlusses ist der Behälter analog der in Fig. 1 dargestellten Version ausgestaltet. Die Verschiusskappe weist zusätzlich zu den Merkmalen, wie sie in der in Fig. 1 dar- gestellten Ausgestaltung vorhanden sind, einen Stütz- und/oder Führungsring 11 auf, der die Halsöffnung außenseitig übergreift und so für eine Gegenkraft gegen den im Inneren verlaufenden Schaft 5 mit Rastnut 6 bilden kann und zusätzlich das Aufstecken durch eine Abschrägung am in Einsteckrichtung liegenden Ende weiter vereinfacht.In the variant of the closure according to the invention shown in Fig. 2, the container is designed analogous to the version shown in Fig. 1. In addition to the features as they are present in the embodiment shown in FIG. 1, the closure cap has a support and / or guide ring 11, which engages over the neck opening on the outside and thus for a counterforce against the shaft 5 extending in the interior can form with locking groove 6 and in addition the attachment by a bevel on the end lying in the insertion further simplified.
[0030] Weiterhin ist auf der zum Behälterhals liegenden Fläche des Schaftes 5 eine umlaufende Ringdichtung 12 zusätzlich zur auf dem Rastkragen 4 liegenden Ringdichtung 9 vorgesehen, was für eine weitere Verbesserung der Dichtigkeit sorgt.Furthermore, a circumferential annular seal 12 is provided in addition to lying on the locking collar 4 ring seal 9 on the lying to the container neck surface of the shaft 5, which ensures a further improvement of the tightness.
[0031] Bei der in Fig. 3 vorgesehenen Ausgestaltung ist die Gestaltung der Verschlusskappe 3 analog der in Fig. 2 dargestellten Kappengestaltung ausgebildet. Allerdings weist der Hals 2 des Getränkebehälters 1 eine umlaufende Halte- und/oder Führungsnut 13 auf, die alternativ dazu dient, dass der Behälter 1 an seinem Hals 2 maschinell ergriffen und bewegt werden kann.In the embodiment provided in FIG. 3, the design of the closure cap 3 is designed analogously to the cap design illustrated in FIG. 2. However, the neck 2 of the beverage container 1 has a circumferential holding and / or guide groove 13, which alternatively serves to enable the container 1 to be gripped and moved by machine at its neck 2.

Ansonsten ist die Gestaltung sowohl der Verschlusskappe 3 als auch des Öffnungsbereiches des Getränkebehälterhalses 2 analog der im vorangegangenen beschriebenen Ausgestaltung.10 still has a holding or guide groove 13. Otherwise, the design of both the cap 3 and the opening portion of the beverage container neck 2 is analogous to that described in the foregoing Design.
[0034] Bei der in Fig. 5 dargestellten Ausgestaltung des erfindungsgemäßen Getränkebehälterhalses 2 ist zusätzlich zu der im vorangegangenen beschriebenen Ausgestaltung ein innen umlaufender Stützring 14 vorgesehen. Dieser stabilisiert die Halsöffnung zunächst mechanisch. Weiterhin ist der Abstand zwischen dem Stützring 14 und der in Öffnungsrichtung gegenüberliegenden Ringfläche 7 des Rastkragens 4 derartig gewählt, dass die Rastnut 6 in die zwischen Stützring 14 und Ringfläche 7 gebildete Nut eingreift. Dabei ist der Abstand weiter-hin so gewählt, dass bei einer Verformung der Verschlusskappe 3 eine Verklemmung zwischen der Nut 6 und dem Stützring 14 in Verbindung mit der Ringfläche 7 erfolgt, was die Stabilität der Gesamtanordnung in derartigen Fällen erheblich erhöhen kann.In the embodiment of the beverage container neck 2 according to the invention shown in Fig. 5, an inner circumferential support ring 14 is provided in addition to the embodiment described in the foregoing. This first stabilizes the neck opening mechanically. Furthermore, the distance between the support ring 14 and the opposite in the opening direction of the annular surface 7 of the locking collar 4 is selected such that the locking groove 6 engages in the formed between the support ring 14 and annular surface 7 groove. The distance is further chosen so that upon deformation of the cap 3 is a deadlock between the groove 6 and the support ring 14 in conjunction with the annular surface 7, which can significantly increase the stability of the overall arrangement in such cases.
[0035] Die in Figur 5 gezeigte Variante wird dahingehend weiter verbessert, dass die Dichtung 15 derart zwischen dem unteren Ende der Rastnut 6 und dem Stützring 14 angeordnet ist, dass der Ringraum 16, welcher sich zwischen Hals 2 und der Rastnut 6 bildet, vollständig hermetisch verschlossen wird. DieThe variant shown in Figure 5 is further improved to the effect that the seal 15 is arranged between the lower end of the locking groove 6 and the support ring 14, that the annular space 16, which forms between the neck 2 and the locking groove 6, completely hermetically sealed. The
Überbrückung des Abstandes zwischen Rastnut 6 und Stützring 14 durch die Dichtung 15 hat eine weitere mechanische Stütze der Verschlusskappe 3 der zur Folge, so dass diese noch flacher und filigraner konstruiert werden kann.Bridging the distance between the locking groove 6 and support ring 14 through the seal 15 has a further mechanical support of the cap 3 of the result, so that it can be constructed even flatter and filigree.
[0036] Natürlich ist die Erfindung nicht auf die vorstehenden Ausführungsbeispiele beschränkt, sondern kann in vielfältiger Hinsicht abgewandelt werden, ohne den Grundgedanken zu verlassen.Of course, the invention is not limited to the above embodiments, but can be modified in many ways, without departing from the spirit.
[0037] So sind beispielsweise die Gestaltungen des Halses genau wie die Dimensionierungen der einzelnen Komponenten vom Einsatzzweck abhängig und variabel. BezugszeichenlisteFor example, the designs of the neck as well as the dimensions of the individual components depending on the purpose and variable. LIST OF REFERENCE NUMBERS
