Abstract

A bung hole closure for cans is described, in which a liquid is stored under pressure or without pressure and from which it is removed under pressure by means of a tap fitting. It comprises a plug-like soft portion bored thru axially having at least one sealing portion in the inside bore, a projection serving for support on the rim region of the can lid surrounding the can opening and a seal seat for the rim of the can opening provided underneath the projection. This soft portion is surrounded by a reinforcing hard portion in the form of a sleeve, which has a projection which is embedded in the projection of the soft portion. The jacket of the sleeve is perforated and has smooth continuous webs and, arranged between these webs, conically outward protruding catches which can be pushed into the material of the soft portion.

Description

Die Erfindung betrifft einen Spundlochverschluss für Dosen, in denen eine Flüssigkeit unter Druck oder ohne Druck aufbewahrt und daraus unter Druck mittels einer Zapfarmatur entnommen wird,bestehend aus einer axial durchbohrten stopfenartigen Spundbüchse mit mindestens einem Dichtteil in der Innenbohrung, einer zur Auflage auf den die Dosenöffnung umgebenden Randbereich des Dosendeckels dienenden Auskragung und einem unterhalb der Auskragung vorgesehenen Dichtsitz für den Rand der Dosenöffnung. The invention relates to a bunghole closure for cans, in which a liquid is kept under pressure or without pressure and is removed therefrom under pressure by means of a tap fitting, consisting of an axially pierced stopper-like bung with at least one sealing part in the inner bore, one for resting on the can opening surrounding edge area of the can lid serving cantilever and a sealing seat provided below the cantilever for the edge of the can opening .

Spundlochverschlüsse dieser Art sind in verschiedenen Ausführungsformen bekannt. Sie werden mit einer Kleinzapfarmatur angestochen, um die Flüssigkeit unter Druck zu zapfen. Der Spundlochverschluss muss einerseits gewährleisten, dass die Dose mit der isobarometrisch eingefüllten Flüssigkeit völlig dicht verschlossen ist und andererseits beim Anstechen der eingeführte Stechdegen der Zapfarmatur so abgedichtet wird, dass die in der Dose herrschenden und auftretenden Druckbedingungen in keiner Weise beeinträchtigt werden. Um einen dichten Sitz in der Dosenöffnung sicherzustellen, ist an der Stoßstelle zwischen der Auskragung und der Aussenwand der bekannten Spundbüchsen eine ringförmige, zweckmässig mit einer Dichtlippe versehene Ausnehmung angeordnet, in die die Randkante des Spundloches eingreift. Das bedeutet, dass gegebenenfalls an dieser Stelle in der Wand der Spundbüchse eine gewisse Schwächung auftritt. Die Dichtung gegenüber dem einzuführenden und eingeführten Stechdegen der Zapfarmatur wird durch zwei oder drei Wulstringe in der Innenbohrung der Spundbüchse erreicht. Für den Dichtvorgang ist eine ausreichende Elastizität der Spundbüchse erforderlich und daher bestehen die bekannten Spundbüchsen aus einem gummiartigen, verhältnismässig weichen Material, das auf eine bestimmte Shorehärte eingestellt sein muss. Bei zu hoher Shorehärte leidet die Dichtigkeit.Bunghole closures of this type are known in various embodiments. They are pierced with a small tap to tap the liquid under pressure. The bunghole closure must on the one hand ensure that the can is completely sealed with the isobarometric liquid and, on the other hand, when the piercing plug is inserted, it is sealed in such a way that the pressure conditions prevailing and occurring in the can are in no way impaired. In order to ensure a tight fit in the Dosenöffnun g , an annular, expediently provided with a sealing lip recess is arranged at the joint between the projection and the outer wall of the known bung bushes, in which engages the edge of the bung hole. This means that there may be a certain weakening at this point in the wall of the sheet pile. The seal against the inserted and inserted prong of the tap fitting is achieved by two or three bead rings in the inner bore of the bung. One is off for the sealing process sufficient elasticity of the bung is necessary and therefore the known bung are made of a rubber-like, relatively soft material that must be adjusted to a certain Shore hardness. If the Shore hardness is too high, the tightness suffers.

Der Nachteil der bekannten Spundlochverschlüsse besteht unter anderem darin, dass eine optimale Dichtung nicht erreicht werden kann. Es müssen daher Kompromisse eingegangen werden, die letztlich doch nicht befriedigende Ergebnisse bringen. So kann das Einbringen der Spundbüchse nie axial und in einem Arbeitsgang erfolgen. Das den Gegenhalt bildende Gummimaterial im Konusbereich der Spundbüchse muss verdrängt werden. Die Montage des Spundlochverschlusses ist nur durch erheblichen, wechselseitigen Kraftaufwand auf den Umfangsrand, beispielsweise durch mehrere Hammerschläge, möglich. Ein Hammerschlag auf frisch abgefülltes Bier ist insbesondere wegen der sofort einsetzenden Entkarbonisierung höchst unerwünscht. Die Auskragung, die auf dem die Dosenöffnung umgebenden Randbereich des Dosendeckels aufliegt, besteht aus dem gleichen weichen Material wie das Dichtteil. Wenn eine solche Spundbüchse mit dem Hammer in die Dosenöffnung eingeschlagen wird, kann es passieren, dass die weiche Auskragung nachgibt und die ganze Spundbüchse in die Dose hineingedrückt wird. Beim Einschlagen muss der Konus der Spundbüchse nachgeben, damit der öffnungsrand in die Ausnehmung an der Aussenwand der Spundbüchse einschnappen kann. Durch die Wucht des Hammerschlags kann aber auch der Dosendeckel verformt werden. Ferner kann beim Anstechen die Gummispundbüchse eingezogen werden, und zwar dann, wenn vor dem Anstechen der in der Regel aus hartem Kunststoff bestehende Stechdegen der Zapfarmatur nicht angefeuchtet wird. Der durch die Wulstringe sowie die in den Wulstringen verankerte und auszustossende Dichtkappe dem Stechdegen entgegengesetzte Widerstand ist dabei häufig so gross, dass die Spundbüchse mit dem Stechdegen in die Dose hineingezogen wird. Schliesslich kann die öffnung des Spundloches auch dadurch verzogen werden, dass bei Lagerung der gefüllten Dose ohne Kühlung, beispielsweise im Sommer durch Erwärmung, der Druck in der Dose ansteigt. Eine verzogene Dosenöffnung verformt aber auch den weichen Spundlochverschluss, so dass die Dichtigkeit leidet.The disadvantage of the known bunghole closures is, among other things, that an optimal seal cannot be achieved. Compromises must therefore be made that ultimately do not lead to satisfactory results. This means that the sheet pile can never be inserted axially and in one operation. The rubber material in the cone area of the sheet pile can be replaced. The bunghole plug can only be installed by considerable mutual force exertion on the peripheral edge, for example by several hammer blows. A hammer blow on freshly bottled beer is highly undesirable, especially because of the immediate decarbonization. The projection, which rests on the edge area of the can lid surrounding the can opening, is made of the same soft material as the sealing part. If such a sheet pile can be hammered into the can opening, the soft overhang can give way and the whole sheet pile can be pressed into the can. When tapping, the cone of the sheet pile must give way so that the opening edge can snap into the recess on the outer wall of the sheet pile. Due to the force of the hammer blow, the can lid can also be deformed. Furthermore, the rubber bung can be retracted when piercing, if the piercing tab of the tap fitting, which is generally made of hard plastic, is not moistened prior to piercing. The one anchored by the bead rings as well as those in the bead rings Butting sealing cap opposing the stab is often so great that the sheet pile can be pulled into the box with the stab. Finally, the opening of the bung can also be distorted by the fact that when the filled can is stored without cooling, for example in the summer by heating, the pressure in the can increases. A warped can opening also deforms the soft bunghole closure, so that the tightness suffers.

Aufgabe der Erfindung ist es, einen Spundlochverschluss der eingangs genannten Art zu schaffen, bei dem die Spundbüchse einerseits eine ausreichende Festigkeit aufweist und andererseits eine einwandfreie Dichtung gewährleistet und somit die Nachteile der bekannten Verschlüsse ausgeschaltet werden und ein automatisches Verschliessen der Dosen auch maschinell ermöglicht wird und Bier nicht schon unmittelbar nach dem Abfüllen durch Hammerschläge beschädigt wird.The object of the invention is to provide a bunghole closure of the type mentioned, in which the bunghole has sufficient strength on the one hand and on the other hand ensures a perfect seal and thus eliminates the disadvantages of the known closures and automatic sealing of the cans is also possible by machine and Beer is not damaged by hammer blows immediately after bottling.

Diese Aufgabe wird dadurch gelöst, dass ein die Spundbüchse bildendes Weichteil und ein dieses verstärkendes Hartteil, vorgesehen ist, das in Form einer Hülse das Weichteil wie ein Käfig umgibt, an einem freien Rand der Hülse eine Auskragung angeformt ist, die in der Auskragung des Weichteils eingebettet ist, der Mantel der Hülse durchbrochen ist, derart, dass von einem der Auskragung gegenüberliegenden Ring der Hülse bis zu einem oberen Abschlussring der Hülse durchgehende-Stege und zwischen jeweils zwei Stegen vom Ring ausgehende, unterhalb des Abschlussringes endende und konisch nach aussen abstehende Schnapper angeordnet sind, und dass die Stege im Material des Weichteils der Spundbüchse bündig eingebettet, die Schnapper dagegen in das Material eindrückbar sind.This object is achieved in that a soft part forming the bung bush and a hard part which reinforces it is provided, which surrounds the soft part in the form of a sleeve like a cage, and a projection is formed on a free edge of the sleeve, which protrudes into the projection of the soft part is embedded, the jacket of the sleeve is perforated such that webs extending from a ring of the sleeve opposite the projection to an upper end ring of the sleeve and between two webs starting from the ring, ending below the end ring and projecting conically outwards are arranged, and that the webs are embedded flush in the material of the soft part of the sheet pile rifle, whereas the catches can be pressed into the material.

Zweckmässige Ausbildungen des Spundlochverschlusses sind in den Unteransprüchen gekennzeichnet.Appropriate designs of the bunghole closure are characterized in the subclaims.

Durch einen solchen Spundlochverschluss werden alle Nachteile der bekannten Spundbüchsen ausgeschaltet. Durch die Kombination des die Dichtung gewährleistenden Weichteils mit einem Hartteil wird ein Eindrücken der Spundbüchse sowohl beim Einsetzen derselben in eine Dosenöffnung als auch beim Anstechen vermieden. Die Auskragung ist durch die Verstärkung aus hartem Material so fest, dass sie sich nicht verformen kann. Ausserdem erhält die Spundbüchse durch das sie umgebende Hartteil eine solche Steifigkeit, dass ein Verziehen der Dosenöffnung und damit ein Verformen der Spundbüchse nicht zu befürchten ist. Hinzu kommt, dass die Montage erleichtert wird. Beim Einsetzen rutscht der Spundlochverschluss dank der glatten Aussenwand der Hülsenteile sowie der Federwirkung der Schnapper leichter in die Dosenöffnung. Sobald die Auskragung der Spundbüchse auf dem Dosendeckel sitzt, spreizen sich die beim Einführen durch den Rand der Dosenöffnung nach innen gedrückten Schnapper wieder nach aussen und rasten am Rand der Dosenöffnung ein. Der Spundlochverschluss wird dabei unlösbar festgehalten. Die Herstellung des erfindungsgemässen Spundlochverschlusses ist äusserst einfach, da er in einem Arbeitsgang durch Spritzen hergestellt werden kann.Such a bunghole closure eliminates all of the disadvantages of the known bung bores. The combination of the soft part, which ensures the seal, with a hard part prevents pressing in of the bung, both when inserting it into a can opening and when piercing. The cantilever is so strong due to the reinforcement made of hard material that it cannot deform. In addition, the hard part that surrounds it gives the sheet pile rifle such a degree of rigidity that there is no need to fear warping of the can opening and thus deformation of the sheet pile rifle. In addition, assembly is made easier. When inserted, the bunghole closure slips more easily into the can opening thanks to the smooth outer wall of the sleeve parts and the spring effect of the catch. As soon as the cantilever of the bung is seated on the can lid, the snaps that are pushed in through the edge of the can opening spread out again and snap into place at the edge of the can opening. The bunghole closure is held permanently. The bunghole closure according to the invention is extremely simple to produce, since it can be produced in one operation by spraying.

Der Spundlochverschluss besteht aus einem Weichteil I und einem Hartteil II.The bunghole closure consists of a soft part I and a hard part II.

Das Weichteil I ist die dichtende Spundbüchse mit einer Auskragung 1 und Dichtteilen, wie Wulstringen 3 in der Innenbohrung. Unterhalb der Auskragung 1 ist im Mantel der Spundbüchse eine umlaufende Fläche 4 vorgesehen, die bei einer bevorzugten Ausführungsform des erfindungsgemässen Spundlochverschlusses die Aufgabe der Dichtung zwischen der Spundbüchse und dem Rand 14 der Dosenöffnung 13 im Dosendeckel 12 übernimmt (Fig. 5). Dadurch wird eine besonders gute Flächendichtung erreicht, die auch bei nicht unter Druck stehenden Dosen hundertprozentige Dichtheit gewährleistet.The soft part I is the sealing bung with a projection 1 and sealing parts, such as bead rings 3 in the inner bore. Below the overhang 1, a circumferential surface 4 is provided in the jacket of the sheet pile, which in a preferred embodiment of the bunghole closure according to the invention takes on the task of sealing between the sheet pile and the edge 14 of the can opening 13 in the can lid 12 (FIG. 5). This results in a particularly good surface seal, which guarantees 100% tightness even with cans not under pressure.

Das Hartteil II verstärkt das für die Dichtung verantwortliche Weichteil I. Es besteht aus einer Hülse 5, die an einem Rand eine Auskragung 6 aufweist. Diese Auskragung 6 ist in der Auskragung 1 des Weichteils I eingebettet (Fig. 2 und 4). Der Mantel der Hülse 5 ist in axialer Richtung durchbrochen. Der der Auskragung 6 gegenüberliegende Rand der Hülse 5 ist durch einen Ring 7 abgeschlossen. Vom Rand dieses Ringes 7 gehen Stege 8 aus, die mit einem oberen Abschlussrand 7' der Hülse 5 verbunden sind. Zwischen jeweils zwei Stegen 8 sind ebenfalls vom Ring 7 ausgehende Schnapper 9 vorgesehen. Diese Schnapper 9 sind nach aussen konisch ausgestellt und enden unterhalb des Abschlussringes 7' der Hülse 5 (Fig. 3). Sie bilden die Verrastung des Spundlochverschlusses in der Dosenöffnung 13.The hard part II reinforces the soft part I responsible for the seal. It consists of a sleeve 5 which has a projection 6 on one edge. This projection 6 is embedded in the projection 1 of the soft part I (FIGS. 2 and 4). The jacket of the sleeve 5 is broken through in the axial direction. The edge of the sleeve 5 opposite the projection 6 is closed by a ring 7. From the edge of this ring 7 go from webs 8, which are connected to an upper end edge 7 'of the sleeve 5. Snaps 9 extending from the ring 7 are also provided between two webs 8. These catches 9 are flared outwards and end below the end ring 7 'of the sleeve 5 (FIG. 3). They form the latching of the bunghole closure in the can opening 13.

Aus den Fig. 2, 2A und 4 ist der zusammengesetzte Spundlochverschluss ersichtlich. Die Hülse 5 des Hartteils II umgibt den Körper des die Spundbüchse bildenden Weichteils I, wobei die Stege 8 im Weichteil I eingebettet sind, dabei aber die Aussenseiten der Stege 8 bündig mit dem Material des Weichteils I liegen. Die Schnapper 9 stehen mit ihren konisch nach aussen verlaufenden Aussenflächen über die Fläche 4 unterhalb der Auskragung 1 des Weichteils I vor. Auf diese Weise entsteht eine Art Ausnehmung unterhalb der Auskragung 1, in die der Rand 14 der Dosenöffnung 13 eingreift. Diese Ausnehmung wird von der weiter oben erwähnten Fläche 4 begrenzt.The assembled bunghole closure can be seen from FIGS. 2, 2A and 4. The sleeve 5 of the hard part II surrounds the body of the soft part I forming the bung bush, the webs 8 being embedded in the soft part I, but the outer sides of the webs 8 being flush with the material of the soft part I. The snappers 9 project with their conically outwardly extending outer surfaces over the surface 4 below the overhang 1 of the soft part I. In this way, a kind of recess is created below the projection 1, in which the edge 14 of the can opening 13 engages. This recess is delimited by the surface 4 mentioned above.

Die Auskragung 6 der Hülse 5 ist in der Auskragung 1 des Weichteils I eingebettet und vollständig von dessen Material umgeben. Die freie Oberseite eines jeden Schnappers 9 ist nahezu vom Material des Weichteils I bedeckt, so dass hier keine schwache oder undichte Stelle entsteht und der die Fläche 4 aufweisende Ring 2 (Fig. 2) des Materials des Weichteils I keine Unterbrechung aufweist.The projection 6 of the sleeve 5 is embedded in the projection 1 of the soft part I and completely surrounded by its material. The free top of each catch 9 is almost covered by the material of the soft part I, so that there is no weak or leaky point here and the ring 2 (FIG. 2) of the material of the soft part I having the surface 4 has no interruption.

Beim Eindrücken des Spundlochverschlusses in die Dosenöffnung 13 werden die Schnapper 9 nach innen in das Material der Spundbüchse gedrückt. Sie schnappen wieder nach aussen, sobald die Auskragung 1 des Verschlusses auf dem Dosendeckel 12 aufliegt und der Rand 14 der Dosenöffnung 13 die Oberkanten der Schnapper 9 freigibt (Fig. 2).When the bunghole closure is pressed into the can opening 13, the catches 9 are pressed inward into the material of the bungie. They snap outwards again as soon as the overhang 1 of the closure on the can lid 12 rests and the edge 14 of the can opening 13 releases the upper edges of the catch 9 (FIG. 2).

Zum Verschliessen der Bohrung der Spundbüchse sind zwei Ausführungsformen möglich.Two embodiments are possible for closing the bore of the sheet pile rifle.

Die der Auskragung 6 gegenüberliegende öffnung der Hülse 5 des Hartteils II kann durch eine am freien Rand des Ringes 7 angeformte Platte 10 verschlossen werden. Diese Platte 10 muss vom Stechdegen der Zapfarmatur durchgestossen werden und zu diesem Zweck sind Sollbruchstellen 10' in der Platte vorgesehen.The opening of the sleeve 5 of the hard part II opposite the projection 6 can be closed by a plate 10 formed on the free edge of the ring 7. This plate 10 must be pierced by the spear of the tap fitting and for this purpose predetermined breaking points 10 'are provided in the plate.

Andererseits kann die Hülse 5 an beiden Enden offen sein. In diesem Fall ist eine an sich bekannte Dichtkappe 11vorgesehen, die die gesamte Bohrung der Spundbüchse einnimmt. Sie ist Dicht- und Abdeckkappe zugleich (Fig. 4).On the other hand, the sleeve 5 can be open at both ends. In this case, a sealing cap 11, known per se, is provided, which takes up the entire bore of the bung. It is a sealing and cover cap at the same time (Fig. 4).

Schliesslich kann der Boden des Weichteils/durch eine durchstossbare Platte oder Membran verschlossen sein (nicht dargestellt), die die Dichtigkeit des einzusetzenden und eingesetzten Spundlochverschlusses sicherstellt. Die Platte oder Membran kann am Bodenrand des Weichteils/angeformt sein.Finally, the bottom of the soft tissue / can be closed by a pierceable plate or membrane (not shown), which ensures the tightness of the bunghole closure to be used and inserted. The plate or membrane can be formed on the bottom edge of the soft tissue.
