Die Erfindung betrifft einen Behälter zur Aufnahme von unter Druck stehenden Getränkeflüssigkeiten, wie Bier, Softdrinks und Weln, der mit einem oben angeordneten, zur Befüllung oder Entleerung der Getränkeflüssigkeit an ein Anschlussstück kuppelbaren, integriert eine Sicherheitsberststelle aufweisenden Fitting versehen ist, wobei die Sicherheitsberststelle am Außenumfang des Fittings als ein einstückig am Fitting vorspringend angeformter, konzentrisch zu einem mit dem Behälterinneren in Strömungsverbindung stehenden Wandungsloch des Fittings angeordneter Ringansatz ausgebildet ist, wobei in dem Ringansatz ein das Wandungsloch abdeckendes und verschließendes, membranartiges Berstelement befestigt ist, wie durch die WO 2006/113416 A1 bekannt geworden. WO 2005/113416 beschreibt einen Behälter gemäß dem Oberbegriff des Anspruchs 1.The invention relates to a container for receiving pressurized beverage liquids, such as beer, soft drinks and Weln, which is provided with a top, for the filling or emptying of the beverage liquid to a connector detachable, integrally provided a security bursting fitting is provided, wherein the Sicherheitsberststelle on the outer periphery of the fitting is formed as an integrally formed on the fitting projecting, concentric with a standing with the container interior in flow connection Wandungsloch the fitting arranged annular projection, wherein in the ring approach a Wandungsloch covering and occlusive, membrane-like bursting element is fixed, as by the WO 2006/113416 A1 known. WO 2005/113416 describes a container according to the preamble of claim 1.

Ein eine Sicherheitsberst- bzw. Sollbruchstelle aufweisender Behälter ist weiterhin durch die EP 0 686 120 B1 bekannt geworden. Dieser aus Metall hergestellte Behälter besitzt einen das Füllgut bzw. die Getränkeflüssigkeit aufnehmenden Hohlkörper, der aus einem Im wesentlichen zylindrischen Mantel und aus zwei nach außen gewölbten Endböden besteht. Mindestens einer der Endböden weist eine Ausformung auf, die vorzugsweise als eine sogenannte Bodentasse aus der Bodenwölbung herausragt, wobei in der Bodentasse ein Behälteranschlussstutzen vorgesehen ist. Zumindest einer der Endböden ist mit einer an seiner Außenseite ausgebildeten Kerbe als Sollbruchstelle versehen, die die Funktion einer Überdrucksicherung bzw. Überlastsicherung erfüllt.A Sicherheitsberst- or predetermined breaking point exhibiting container is still through the EP 0 686 120 B1 known. This container made of metal has a filling material or beverage liquid receiving hollow body, which consists of a substantially cylindrical shell and two outwardly curved end floors. At least one of the end floors has a shape, which preferably protrudes as a so-called ground cup from the bottom curvature, wherein in the bottom cup a container connection piece is provided. At least one of the end floors is provided with a notch formed on its outside as a predetermined breaking point, which fulfills the function of an overpressure protection or overload protection.

Die Überdrucksicherung, die in verschiedenen Varianten aus der DE 4041 636 A1 bekannt ist, soll verhindern, dass bei unsachgemäßer Behandlung des Behälters sowie bei Fehlbedienung oder Funktionsausfall von Druckminderorganen der Behälterinnendruck bis zum Bersten des Behälters auf sehr hohe Werte ansteigt. Vielmehr soll in einem definierten Druckabstand vom maximalen Berstdruck des Behälters auf gefahrlose Weise der entstandene Überdruck durch selbsttätiges Öffnen der Sicherheitsberststelle bzw. -bruchstelle In der Behälterwandung abgeleitet werden.The overpressure protection, which in different variants from the DE 4041 636 A1 is known to prevent improper handling of the container and in the event of incorrect operation or malfunction of pressure-reducing organs, the internal pressure of the container rises to very high values until the container bursts. Rather, in a defined pressure separation from the maximum bursting pressure of the container in a safe way, the resulting overpressure should be derived by automatically opening the safety bursting point or break point in the container wall.

Aus der WO 2010/091775 A1 ist ein Behälter mit einer darin vorgesehenen Blase bekannt, die oben, an ihrem Kopfende mit einem kragenartigen Anschlussmittel ausgebildet Ist, dass zum Abfüllen der Flüssigkeit mit einem Fitting bzw. Sicherheitsfitting verbindbar ist, der verschließbare Durchgangsöffnungen für einerseits ein Druckgas und andererseits die Getränkeflüssigkeit besitzt. Die Behälter bzw. Blasen, insbesondere hergestellt aus PET, kommen zum mit CO2-Druckgas betriebenen Ausschank von auf Trinktemperatur temperierten Getränken zum Einsatz. Über den oben am Behälter bzw. der Blase angeordneten Fitting, der ein Getränke- und ein Gasventil aufweist und über einen einen Anschlusskragen des Behälters bzw. der Blase mit einer Rastnut des Fittings von außen her verbindenden Adapterring befestigt ist, aufsetzbaren Zapfkopf bzw, ein aufsetzbares Anschlussstück kann das Getränk entnommen bzw. der Behälter/die Blase befüllt werden. Das Getränk wird hierbei über ein von oben in den Behälter hineinragendes Steigrohr zum Getränkeauslass ausgetrieben.From the WO 2010/091775 A1 a container with a bladder therein is known, which is formed at the top, at its head end with a collar-like connection means that for filling the liquid with a fitting or safety fitting is connectable, the closable through-openings for on the one hand a compressed gas and on the other hand has the beverage liquid. The containers or bubbles, in particular made of PET, are used for serving with CO 2 -discharge gas of beverages tempered to drinking temperature. About the top of the container or the bladder arranged fitting having a beverage and a gas valve and is attached via a connection collar of the container or the bladder with a locking groove of the fitting connecting from the outside adapter ring, attachable tap head or, an attachable Connecting piece can be removed from the drink or the container / the bladder be filled. The drink is here expelled via a projecting into the container from above riser to the beverage outlet.

Eine Getränke-Ausschankeinrichtung mit einem oben am Flüssigkeitsbehälter angeordneten Fitting ist weiterhin aus der EP 2 121 505 B1 bekannt. Zur Befestigung des Fittings ist eine Behälteröffnung zur Außenseite hin mit einer Aufbördelung ausgebildet, die von einem Verbindungsstück, beispielsweise ein metallischer Pressring oder ein aufschraubbarer Kunststoffring, umgriffen wird. Das Steig- bzw. Fittingrohr ist dort als in seiner Längsrichtung verstellbarer, beweglicher Bestandteil der Dichtung ausgebildet und gestuft positionierbar.A beverage dispensing device with a top of the liquid container arranged fitting is further from the EP 2 121 505 B1 known. For attachment of the fitting, a container opening is formed to the outside with a flaring, which is encompassed by a connector, such as a metallic press ring or a screw-on plastic ring. The riser or fitting tube is designed there as a movable part of the seal which is adjustable in its longitudinal direction and can be positioned in a stepped manner.

Der Erfindung liegt die Aufgabe zugrunde, einen Behälter der eingangs genannten Art zu schaffen, bei dem in einfacherer Weise eine Sicherheitsberststelle mit zudem besserer Funktionalität vorgesehen werden kann.The invention has for its object to provide a container of the type mentioned, in which in a simpler manner a security bursting point can also be provided with better functionality.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, dass ein von außen mit einem zylindrischen Formkopf in den radial vorspringend vorgesehenen Ringansatz eingestecktes oder auf diesen aufgestecktes Perforationselement eine dem membranartigen Berstelement zugewandte Spitze und zur manuellen Entlastung der Sicherheitsberststelle eine sich dem Formkopf in Umfangsrichtung des Fittings anschließende, beim Abheben vom Fitting weg die Spitze in das membranartige Berstelement bewegende Lasche aufweist. Die somit bidirektionale Sicherheitsberststelle des Fittings, z.B. ein Korb-, Flach- oder Dreikantfitting, bietet erfindungsgemäß eine Zusatzfunktion, nämlich neben der Überdruck- bzw. Überlastsicherung eine gezielte, manuell von außen einzuleitende Druckentlastung, wie insbesondere zur Gewährleistung eines völlig drucklosen Behälters zu dessen Entsorgung. Denn durch Ziehen an der Lasche bewegt sich die ansonsten stationäre Spitze in Richtung auf den Behälter bzw. dessen membranartiges Berstelement und durchsticht bzw. zerstört dieses. Durch den in den Ringansatz eintauchenden Formkopf, der durch Klemmung, Verschwelung oder -klebung Im bzw. auf dem Ringansatz gehalten werden kann, lässt sich das membranartige Berstelement auch lose, gegebenenfalls unter Zwischenschaltung eines Dichtrings, In den Ringansatz einsetzen.This object is achieved in that a plugged from the outside with a cylindrical mold head in the radially projecting annular approach or plugged onto this perforation a membrane-like bursting element facing tip and manual relief of Sicherheitsberststelle a the forming head in the circumferential direction of the fitting subsequent, at Lift off the fitting away the tip has in the membrane-like bursting element moving tab. The thus bidirectional bursting point of the fitting, e.g. a basket, flat or triangular fitting, according to the invention offers an additional function, namely in addition to the overpressure or overload protection targeted, manually initiated from the outside pressure relief, in particular to ensure a completely pressureless container for its disposal. For by pulling on the tab, the otherwise stationary tip moves in the direction of the container or its membrane-like bursting element and pierces or destroys this. By dipping into the ring approach mold head, which can be held by clamping, charring or gluing in or on the ring approach, the membrane-like bursting element can also loose, possibly with the interposition of a sealing ring, in the ring approach to use.

Zur einfacheren Betätigung und Einleitung der gezielten manuellen Druckentlastung wird erfindungsgemäß vorgeschlagen, dass an die Lasche eine nach außen vorstehende Auslösenase angeformt ist. Die sich an den Außenumfang über ihre begrenzte Länge an die Wandung des Fitting anschmiegende Lasche lässt sich somit über die gleichzeitig zur Druckentlastung dienende Auslösenase bequem ergreifen und wegziehen.For easier operation and initiation of targeted manual pressure relief, the invention proposes that an outwardly projecting release tab is formed on the tab. The adjoining the outer circumference over its limited length to the wall of the fitting tab can thus take over the same time serving to relieve pressure release lug comfortably and pull away.

Nach einem weiteren Vorschlag der Erfindung ist die Lasche im Bereich zwischen der Auslösenase und dem Formkopf mit einem sich über ihre Breite erstreckenden Filmscharnier ausgebildet. Es lässt sich damit der Originalitätszustand der Sicherheitsberststelle kontrollieren. Denn wenn diese zur Druckentlastung schon manuell betätigt worden ist, wird das durch das dann gebrochene Filmscharnier sofort erkennbar.According to a further proposal of the invention, the tab is formed in the region between the release tab and the forming head with a film hinge extending over its width. It can thus control the originality state of the security burst station. Because if this has already been manually operated to relieve pressure, the then broken film hinge is immediately recognizable.

Weitere Merkmale und Einzelheiten der Erfindung ergeben sich aus den Ansprüchen und der nachfolgenden Beschreibung eines in den Zeichnungen schematisch dargestellten Ausführungsbeispiels der Erfindung. Es zeigen:

Ein im Ausführungsbeispiel nach Fig. 1 dargestellter Behälter 1 zur Aufnahme bzw. zur druckgasbetriebenen Abgabe von Getränkeflüssigkeiten wie Bier, Softdrinks und Wein, besteht aus einem äußeren Stahlmantel 2 und einer darin angeordneten Blas 3 aus thermoplastischem Kunststoffmaterial, insbesondere PET.One in the embodiment according to Fig. 1 illustrated container 1 for receiving or for pressurized gas dispensing of beverage liquids such as beer, soft drinks and wine, consists of an outer steel shell 2 and a blast 3 arranged therein made of thermoplastic material, in particular PET.

An der Oberseite des Behälters 1 ist über einen Adapterring 4 ein Fitting 5 befestigt, der ein in die Blase 3 hineinragendes Steigrohr 6 aufweist, über das die Flüssigkeit aufsteigt. An den Fitting 5 lässt sich zum Befüllen mit einer Getränkeflüssigkeit in beispielsweise einer Brauerei ein Anschlussstück oder zum Zapfen durch den Verbraucher ein Zapfkopf anschließen. Der Fitting 5 ist, wie bekannt, mit Strömungskanälen für einerseits ein Druckgas und andererseits die Flüssigkeit versehen.At the top of the container 1, a fitting 5 is attached via an adapter ring 4, which has a protruding into the bubble 3 riser 6, via which the liquid rises. To the fitting 5 can be connected for filling with a beverage liquid in, for example, a brewery a connection piece or for tapping by the consumer a tap head. The fitting 5 is, as known, provided with flow channels for on the one hand a compressed gas and on the other hand, the liquid.

Wie sich den Fig. 2 bis 4 entnehmen lässt, ist der Fitting 5 an seinem Außenumfang mit einer Sicherheitsberststelle 7 ausgebildet. Hierzu ist einstückig mit dem Fitting 5 ein radial nach außen vorspringender Ringansatz 8 angeformt, der konzentrisch ein über einen Strömungskanal 9 und die Strömungskanäle des Fittings mit dem Behälterinnern in Verbindung stehendes Wandungsloch 10 umschließt (vgl. Fig. 3). In den Ringansatz wird hier unter Zwischenschaltung eines Dichtungsringes 11 ein membranartiges Berstelement 12 eingesetzt, das das Wandungsloch 10 verschließt bzw. abdeckt und bei auftretendem Überdruck (maximal 25 bar, bei dünnwandigen Behältern niedriger) anspricht bzw. öffnet.How the Fig. 2 to 4 can be seen, the fitting 5 is formed on its outer circumference with a Sicherheitsberststelle 7. For this purpose, integrally formed with the fitting 5 is a radially outwardly projecting annular shoulder 8 which concentrically surrounds a wall hole 10 communicating with the container interior via a flow channel 9 and the flow channels of the fitting (cf. Fig. 3 ). In the ring approach a membrane-like bursting element 12 is inserted here with the interposition of a sealing ring 11, which is the Wandungsloch 10 closes or covers and responds or opens when overpressure occurs (maximum 25 bar, lower for thin-walled containers).

Das optional beispielsweise einzuklebende membranartige Berstelement 12 wird in dem Ringansatz 8 durch ein Perforationselement 13 gehalten, das mit einem Formkopf 14 in den Ringansatz 8 eingesteckt und dort durch beispielsweise Klemmung fixiert wird.The optionally membrane-like rupture element 12 to be adhesively bonded, for example, is held in the annular shoulder 8 by a perforation element 13, which is inserted into the annular shoulder 8 with a forming head 14 and fixed there by clamping, for example.

Der Formkopf 14 ist mit einer nach innen vorstehenden, dem membranartigen Berstelement 12 zugewandten Spitze 15 ausgebildet (vgl. Fig. 3), die das Ansprechen bzw. Öffnen der Sicherheitsberststelle 7 unterstützt, weil sie dazu beiträgt, dass das bei Überdruck nach außen beaufschlagte Berstelement 12 spätestens sicher dann einreißt bzw. zerstört wird, wenn es auf die Spitze 15 auftrifft.The forming head 14 is formed with an inwardly projecting, the membrane-like bursting element 12 facing tip 15 (see. Fig. 3 ), which supports the response or opening of the safety bursting point 7, because it contributes to the fact that the bursting element 12, which is acted upon in the event of overpressure, then tears or is destroyed at the latest when it strikes the tip 15.

Das Perforationselement 13 ist weiterhin mit einer Lasche 16 versehen, die sich in der in Fig. 4 dargestellten, fertig montierten Einbausituation ihrer Länge entsprechend an die Wandung des Fittings 5 anschmiegt. Die Sicherheitsberststelle 7 erhält durch das Perforationselement 13 eine Zusatzfunktion, nämlich eine gezielte manuelle Druckentlastung durch abheben bzw. wegziehen der Lasche 16 von dem Fitting 5, wodurch die Spitze 15 in Richtung auf das membranartige Berstelement 12, in dieses zerstörend eindringend, bewegt wird. Zum handhabungsfreundlichen Ab- bzw. Wegziehen der Lasche 16 ist diese mit einer Auslösenase 17 versehen.The perforation element 13 is further provided with a tab 16, which in the in Fig. 4 illustrated, fully assembled installation situation of their length conforms to the wall of the fitting 5. The Sicherheitsberststelle 7 receives by the perforation 13 an additional function, namely a targeted manual pressure relief by lifting or pulling away the tab 16 of the fitting 5, whereby the tip 15 in the direction of the membrane-like bursting element 12, in this destructively penetrating, is moved. For handling-friendly removal or removal of the tab 16, this is provided with a release lug 17.

In dem Bereich zwischen der Auslösenase 17 und dem Formkopf 14 verläuft über die Breite der Lasche 16, d.h. von oben nach unten, ein Filmscharnier 18, das eine Prüfung des Originalitätszustands der Sicherheitsberststelle 7 erlaubt, indem durch in Augenscheinnahme sofort erkennbar ist, ob das Filmscharnier bereits gebrochen ist und somit eine manuelle Druckentlastung zuvor schon durchgeführt wurde.In the area between the release tab 17 and the forming head 14 extends across the width of the tab 16, ie from top to bottom, a living hinge 18, which allows a check on the originality state of the security burst 7 by immediately recognizable by visual inspection, whether the film hinge already broken and thus a manual pressure relief has already been carried out.
