A description is given of a container closure for filling and emptying containers, in particular drum-like transporting containers, which can be inserted in an exchangeable manner into a container opening, which receives a plug head. The container closure has a riser tube, which is connected to the plug head, and a removal connection element, it being the case that the latter can be locked to the plug head by means of a stud coding system which has coding studs and matching coding recesses. According to the invention, the coding studs are provided on a first securing part and the coding recesses are provided on a second securing part. One of the securing parts is designed as an annular disc, which can separately be fitted loosely, such that it cannot slip off, onto the modular removal connection element. The other of the securing parts is integrated in the plug head. The container closure described avoids mix-up of chemicals, permits simultaneous liquid removal and ventilation, and, while complying with the regulations for licensing hazardous substances, can be connected to commercially available containers or drums.

Description

Die Erfindung betrifft einen Behälterverschluß mit den Merkmalen gemäß Oberbegriff von Anspruch 1.The invention relates to a container closure with the features according to Preamble of claim 1.

Derartige Behälterverschlüsse sind bekannt. In der US-A-4,699,298 (DE-A-3 608 300) ist eine Verbindungsvorrichtung zum Einsetzen von Rohren bzw. Röhren in die Spundöffnung eines Fasses zum Fördern von Flüssigkeit aus dem Faß beschrieben. Zur Vermeidung von Verunreinigungen der aus dem Faß zu fördernden Flüssigkeiten weist die Verbindungsvorrichtung ein mechanisches Stiftcodiersystem auf, welches Vorsprünge und Ausnehmungen aufweist, so daß ein bestimmtes Entnahmeelement an den Spundkörper nur anschließbar ist, wenn die entsprechenden Vorsprünge und Ausnehmungen entsprechend dem Codiersystem zueinander passen. Mittels eines außen übergreifenden Überwurfringes wird das Entnahmeelement, in welches ein jeweiliger Teil des Stiftcodiersystems fest integriert ist, d.h. eine Einheit mit dem Entnahmeelement bildet, verschraubt. Für verschiedene Stoffe, welche verschiedene Stiftcodiersysteme erfordern, um ein unbeabsichtigtes Kombinieren von Systemen, welche bereits für unterschiedliche Flüssigkeiten verwendet worden sind, sind daher die entsprechenden Entnahmeelemente komplett unterschiedlich zu gestalten. Dies macht derartige Behälterverschlüsse relativ teuer, da sie quasi in Einzelfertigung hergestellt werden müssen.Such container closures are known. One is in US-A-4,699,298 (DE-A-3 608 300) Connection device for inserting pipes or tubes in the Bung opening of a barrel for pumping liquid out of the barrel described. To avoid contamination from the barrel too conveying liquids, the connecting device has a mechanical Pen coding system, which has projections and recesses, so that a certain removal element can only be connected to the sheet pile is when the corresponding protrusions and recesses correspond the coding system fit together. By means of an overarching The ring is the removal element, in which a respective part of the pin coding system is firmly integrated, i.e. one unit with the removal element forms, screwed. For different fabrics, which different Pen coding systems require in order to inadvertently combine Systems that have already been used for different liquids the corresponding removal elements are completely different to design. This makes such container closures relatively expensive because they almost have to be manufactured individually.

Des weiteren ist aus der US-A-3,913,608 ein Behälteranschlußelement bekannt, welches einen Bajonettverschluß aufweist, um ein Anschlußelement rasch und leicht von einem Stutzen eines Behälters entfernen bzw. an diesen anbringen zu können. Eine zusätzliche Sicherung gegen unbeabsichtigtes Anschließen eines Elementes, welches bereits für eine andere Flüssigkeit als die in dem Behälter befindliche verwendet wurde, ist nicht vorgesehen.Furthermore, a container connecting element is known from US-A-3,913,608, which has a bayonet lock around a connecting element quickly and easily remove from or on a nozzle of a container to be able to attach. An additional safeguard against accidental Connect an element that is already for a liquid other than the one used in the container is not intended.

Aus der DE-PS 103116 ist ein Faßverschluß bekannt, mittels welchem ein Füllen bzw. Entleeren eines Fasses unter Druck ohne Anbohren des Verbundes ermöglicht ist. In dem beschriebenen Faßverschluß ist in seinem Spund eine Ventilanordnung vorgesehen, welche dadurch geöffnet bzw. geschlossen werden kann, daß ein zum Spund passender Ausschankstutzen aufgeschraubt wird, welcher Rohransätze aufweist, mittels welchen die Ventile geöffnet bzw. bei Entfernen derselben wieder geschlossen werden. Ein Stiftcodiersystem zur Sicherung des Anschlusses eines speziellen Stutzens für einen speziellen Spund ist nicht beschrieben.From DE-PS 103116 a barrel closure is known, by means of which a Filling or emptying a barrel under pressure without drilling the composite is possible. In the barrel closure described is in his Bung provided a valve arrangement which thereby opened or it can be concluded that a serving nozzle matching the bung is screwed on, which has pipe lugs, by means of which the Open valves or close them again when removing them. A pin coding system to secure the connection of a special connector for a special bung is not described.

Des weiteren ist in der US-A-3,905,522 eine Flüssigkeitsausgabevorrichtung zur Verwendung mit einem Anschlußhahn bzw. einem Anschlußelement für Flüssigkeitsbehälter beschrieben. Diese Vorrichtung weist einen Spundkopf auf, welcher ein sich in das Innere eines zu entleerenden Fasses erstreckendes abgewinkeltes Siphonrohr trägt und an welchem mittels Schraubgewinde ein Entnahmeelement an der Außenseite eines Fasses anschließbar ist, welches mit entsprechenden Flüssigkeitsleitungen verbunden ist. Die Vorrichtung weist kein Stiftcodiersystem auf. Das Siphonrohr erstreckt sich vom Spundkörper aus in einem Winkel bezüglich der Mittelachse der Vorrichtung in das Faß hinein, wobei das daran sich anschließende wiederum zurückgewinkelte Stück des Siphonrohres mit seinem Ende bis auf die gedachte Mittelachse der Vorrichtung zurückgeführt ist. Die Abwinkelung des Siphonrohres soll verhindern, daß das im Faß verbleibende Rohr mit der Faßfüllausrüstung kollidiert bzw. das Füllen stört.Also in US-A-3,905,522 is a liquid dispenser for use with a connection tap or a connection element for Liquid container described. This device has a bung head which extends into the interior of a barrel to be emptied angled siphon tube carries and on which by means of screw thread a removal element can be connected to the outside of a barrel, which is connected to corresponding liquid lines. The device does not have a pen coding system. The siphon tube extends from Sheet piling at an angle with respect to the central axis of the device into the barrel, the one following it, again angled back Piece of the siphon tube with its end up to the imaginary Center axis of the device is returned. The bend of the siphon tube is to prevent the tube remaining in the barrel with the barrel filling equipment collides or interferes with the filling.

Das Dokument DE-A 36 08 300 beschreibt eine Spundverbindung für einen festen Behälter aus einem Spundkörper, der in ein Spundloch des Behälters eingeschraubt wird, und Steigrohren, die durch Löcher in dem Spundkörper geführt werden.

Accordingly, the coding pins 4 as cylindrical pins 4 'and circular segment-shaped pins 4 "(Fig. 3 and 4).

Der die Stiftscheibe tragende Überwurfstopfen 6 ist auf dem zylindrischen Teil des Entnahmeanschlußelementes 3 gegen Abstreifen gesichert, so daß er nach seiner Montage auf diesem zylindrischen Teil des ansonsten für unterschiedliche Chemikalien vollkommen gleich ausgebildeten Entnahmeanschlußelementes 3 von diesem nicht mehr ohne weiteres entfernbar ist.The cap plug 6 carrying the pin washer is on the cylindrical Part of the removal connector 3 secured against stripping so that it after mounting it on this cylindrical part of the otherwise for different Chemicals completely identical trained connection element 3 of this is no longer easily removable.

Wenn das Entnahmeanschlußelement 3 mit dem Spundkopf 1 verbunden werden soll, wobei entsprechend dem Stiftcodiersystem nur eine codierte Anordnung von zylinderförmigen und kreisringsegmentförmigen Stiften zu den entsprechend geformten Ausnehmungen paßt, so wird zunächst das Entnahmeanschlußelement mit seinem zylindrischen Rohrabschnitt 16 in den Spundkopf 1 bis in den Bereich des zylindrischen Teils 15 des Spundkopfes 1 eingesteckt. Anschließend wird die Stiftscheibe 7 so gedreht, daß ihre Codierstifte 4 zu den entsprechenden Codierausnehmungen 5 passen und mit diesen Stiften in diese Codierausnehmungen eingesetzt, bis die Stiftscheibe 7 auf der äußeren Stirnfläche des Spundkopfes 1 aufliegt. Anschließend wird der mit seinem Gewindeabschnitt 11 den zentralen Bereich der Stiftscheibe 7 durchgreifende Überwurfstopfen 6 in den abgesenkten Innengewindeabschnitt 12 des Spundkopfes 1 eingeschraubt, bis das Entnahmeanschlußelement 3 fest mit dem Spundkopf 1 verbunden ist. Damit der Überwurfstopfen 6 mit der Stiftscheibe 7 nicht von dem zylindrischen Teil des Entnahmeanschlußelementes entfernbar ist, besitzt letzteres am Ende des zylindrischen Abschnittes einen Anschlagflansch 13. An der Stirnseite dieses Anschlagflansches 13 ist ein in einer Nut angeordneter erster O-Ring 14 vorgesehen, welcher im montierten Zustand eine Dichtung des Entnahmeanschlußelementes 3 im Spundkopf 1 schafft. Dabei ruht dieser erste O-Ring 14 auf einer im Innern des Spundkopfes 1 am Ende des abgesenkten Innengewindeabschnittes 12 angeordneten Schulter.When the removal connector 3 is connected to the bung head 1 should be, according to the pen coding system only one coded Arrangement of cylindrical and circular segment-shaped pins to the suitably shaped recesses fits, so the removal connector is first with its cylindrical tube section 16 in the bung head 1 to the area of the cylindrical part 15 of the bung head 1 plugged in. Then the pin disc 7 is rotated so that its Coding pins 4 match the corresponding coding recesses 5 and with inserted these pins into these coding recesses until the pin washer 7 rests on the outer end face of the bung head 1. Then will with its threaded section 11 the central area of the pin disc 7 penetrating cap 6 in the lowered internal thread section 12 of the bung head 1 screwed in until the removal connection element 3 is firmly connected to the bung head 1. So that the cap 6 with the pin washer 7 not from the cylindrical part of the removal connection element is removable, the latter has at the end of the cylindrical Section a stop flange 13. On the end face of this stop flange 13 a first O-ring 14 arranged in a groove is provided, which in the assembled state a seal of the removal connection element 3 in the bung head 1 creates. This first O-ring 14 rests on an im Inside of the bung head 1 at the end of the lowered internal thread section 12 arranged shoulder.

Der Spundkopf 1 besitzt einen in Richtung des Behälterinneren weisenden zylindrischen Teil 15. In diesem zylindrischen Teil ist eine Belüftungsöffnung 17 vorgesehen. Der Innendurchmesser dieses zylindrischen Teils 15 des Spundkopfes 1 ist größer als der Außendurchmesser des zylindrischen Rohrabschnittes 16 des Entnahmeanschlußelementes 3, wobei unterhalb der Belüftungsöffnung 17 eine Ringschulter 19 angeordnet ist, von welcher ab sich der Innendurchmesser des zylindrischen Teils 15 des Spundkopfes 1 verringert. Auch dieser Abschnitt verringerten Durchmessers unterhalb der Ringschulter 19 im zylindrischen Teil 15 des Spundkopfes 1 ist bezüglich seines Innendurchmessers noch größer als der Außendurchmesser des zylindrischen Rohrabschnittes 16 des Entnahmeanschlußelementes 3. An einer Stelle des zylindrischen Rohrabschnittes 16 des Entnahmeanschlußelementes 3, welcher sich im montierten Zustand des Entnahmeanschlußelementes 3 im zylindrischen Teil 15 des Spundkopfes 1 unterhalb der Belüftungsöffnung 17 befindet, ist ein zweiter, in eine Nut eingelassener O-Ring 18 vorgesehen, welcher einen Raum zur Be- und Entlüftung nach unten in das Steigrohr 2 abdichtet, welcher zwischen der Innenfläche des zylindrischen Teils 15 des Spundkopfes und der Außenfläche des zylindrischen Rohrabschnittes 16 des Entnahmeanschlußelementes 3 vorhanden ist.The bung head 1 has one pointing in the direction of the interior of the container cylindrical part 15. In this cylindrical part there is a ventilation opening 17 provided. The inside diameter of this cylindrical part 15 of the Sheet head 1 is larger than the outer diameter of the cylindrical Pipe section 16 of the removal connector 3, below the Ventilation opening 17, an annular shoulder 19 is arranged, from which the inner diameter of the cylindrical part 15 of the bung head 1 decreased. This section of reduced diameter below the Ring shoulder 19 in the cylindrical part 15 of the bung head 1 is relative its inner diameter is still larger than the outer diameter of the cylindrical Pipe section 16 of the removal connector element 3. At one Place of the cylindrical tube section 16 of the removal connection element 3, which is in the assembled state of the removal connection element 3 in cylindrical part 15 of the bung head 1 below the ventilation opening 17th there is a second O-ring 18 embedded in a groove, which has a space for ventilation in the riser pipe 2 seals which between the inner surface of the cylindrical part 15 of the Bung head and the outer surface of the cylindrical tube section 16 of the Discharge connection element 3 is present.

Dieser zylindrische Rohrabschnitt 16 des Entnahmeanschlußelementes 3 ist bis weit ins Innere des Entnahmeanschlußelementes 3 in Form eines zylindrischen Ringspaltes gemäß Fig. 1 nach oben geführt, und zwar bis in einen verdickten Bereich des Entnahmeanschlußeiementes 3, an welchem Entlüftungsventile bzw. Leitungen in einen Anschlußstutzen 20 einschraubbar sind, über welche die entsprechende Lüftung erfolgt. This cylindrical tube section 16 of the removal connection element 3 is to the inside of the removal connection element 3 in the form of a cylindrical 1, up to one thickened area of the extraction connection element 3, on which vent valves or lines can be screwed into a connecting piece 20, through which the appropriate ventilation takes place.

Auf dem in den Behälter hineinreichenden zylindrischen Teil 15 des Spundkopfes 1 ist ein Steigrohr 2 straff sitzend aufgeschoben, so daß es durch diesen zylindrischen Teil 15 gehalten wird. Am unteren Ende des Steigrohres 2 ist ein Öffnungstrichter 9 angeordnet, welcher bei eingesetztem Spundkopf 1 auf dem Behälterboden aufsitzt. Der Öffnungstrichter weist an seiner dem Behälterboden zugewandten Stirnfläche umfangsmäßig voneinander beabstandete Stege 10 auf, welche gewährleisten, daß bei auf dem Behälterboden aufgesetztem Öffnungstrichter 9 des Steigrohres 2 zwischen dem Behälterboden und den Stegen 10 ein ausreichender Strömungsquerschnitt vorhanden ist. Durch die Stege 10 wird des weiteren gewährleistet, daß beim Einschrauben des Spundkopfes 1 in die Behälteröffnung möglichst wenig Material des Öffnungstrichters 9 in Reibkontakt mit dem Behälterboden bzw. der Behälterwand kommt, so daß die Menge gegebenenfalls abgeriebener Teilchen minimiert bzw. gänzlich vermieden wird.On the cylindrical part 15 of the bung head reaching into the container 1, a riser pipe 2 is pushed tightly so that it passes through this cylindrical part 15 is held. At the bottom of the riser 2, an opening funnel 9 is arranged, which when the bung head is inserted 1 sits on the bottom of the container. The opening funnel points to his the end face facing the container bottom circumferentially from one another spaced webs 10, which ensure that when on the container bottom attached opening funnel 9 of the riser pipe 2 between the Container bottom and the webs 10 have a sufficient flow cross-section is available. The webs 10 further ensure that when screwing the bung head 1 into the container opening if possible little material of the opening funnel 9 in frictional contact with the bottom of the container or the container wall comes, so that the amount if necessary abraded particles are minimized or completely avoided.

Im Bereich zwischen dem auf den zylindrischen Teil des Spundkopfes 1 aufgesetzten oberen Teil des Steigrohres 2 und seinem Öffnungstrichter 9 befindet sich ein Abschnitt, welcher als Faltenbalg 8 ausgebildet ist. Durch diesen Faltenbalg 8 können mehrere Zentimeter in Längsrichtung zur Anpassung an unterschiedliche Abstände zwischen einem Boden bzw. einer Wand eines Behälters und dem gegenüberliegenden in eine Behälteröffnung eingeschraubten Spundkopf 1 ausgeglichen werden. Auch dadurch ist es möglich, ein und denselben Behälterverschluß für verschiedene Behälterabmessungen und Behälterarten einzusetzen. Darüber hinaus dient der Faltenbalg 8 dazu, gegebenenfalls vorhandene Neigungen des Behälterbodens oder der Behälterwand, auf welchem bzw. auf welcher der Öffnungstrichter 9 aufgesetzt wird, auszugleichen, ohne daß ein Abknicken des Steigrohres 2 beim Einsetzen des Spundkopfes 1 in die Öffnung des Behälters auftreten kann. In the area between the cylindrical part of the bung head 1 the upper part of the riser 2 and its opening funnel 9 there is a section which is designed as a bellows 8. By this bellows 8 can be adjusted several centimeters in the longitudinal direction to different distances between a floor or a wall one container and the opposite screwed into a container opening Sheet head 1 can be compensated. This also makes it possible one and the same container closure for different container dimensions and container types. The bellows 8 also serves in addition, any existing inclinations of the container bottom or Container wall, on which or on which the opening funnel 9 is placed will compensate for, without kinking the riser 2 when Insertion of the bung head 1 into the opening of the container can occur.

Vielmehr ist anstelle dessen ein Gewindestopfen 22 in den Spundkopf 1 eingesetzt. Der Gewindestopfen 22 ist in einen Gewindeabschnitt des Spundkopfes 1 dichtend einschraubbar, welcher zu dem den Überwurfstopfen 6 aufnehmenden abgesenkten Innengewindeabschnitt 12 nach innen abgesetzt ist. Die Behälter können entweder mit einem herkömmlichen Verschluß versehen sein, oder können bereits mit einem derartigen Spundkopf ausgerüstet sein, welcher im Anlieferungszustand den Gewindestopfen 22 zum Verschließen trägt. Dadurch ist gewährleistet, daß lediglich eine zu den durch die Codierausnehmungen 5 in dem Spundkopf 1 vorgegebenen Formen und Abstände passende Codierstiftanordnung und damit ein bestimmtes Entnahmeanschlußelement 3 paßt. Somit ist durch das vorgegebene Stiftcodiersystem eine Verwechselung von Chemikalien ausgeschlossen.In Fig. 2 a bung head 1 carrying the riser pipe 2 is shown, wherein in this representation the removal connection element 3 is not used. Instead, there is a threaded plug 22 in the bung head 1 used.
