Definitions
- the invention relates to a sealing cap for a security lock.
- Generic sealing caps made of plastic have become known from DE-A's 36 37 644 and 33 15 548.
- the object of the invention is therefore to provide a sealing cap of the type mentioned, which can be applied in a simple manner.
- a locking screw which has at least one circumferential groove on the inner edge of its recess
- two are articulated as an anchoring element the anchoring flaps connected to the cover surface project downward, each having on their outer edge in the circumferential groove on the inner edge of the locking screw engaging anchoring teeth, and that the two anchoring flaps are connected to one another by two articulated bracing struts which are supported on the bottom of the recess of the locking screw.
- Such a circumferential groove is usually already formed on the inner edge of the recess of the locking screw by the production of the external thread of the locking screw, so that this groove or several grooves can be used as undercuts for anchoring the sealing cap.
- connection of the two anchoring flaps pivotally attached to the cover surface by the common expansion struts ensures that the two anchoring flaps are held in place in their anchoring position with great rigidity because the two anchoring flaps are supported diagonally against one another via the expansion struts.
- the sealing cap which in the closed state is a largely rigid component in itself, can only be released after destruction. The requirements for a tamper-evident closure are therefore met to a high degree.
- the sealing cap is put on in a simple manner by pressure or impact from above.
- the force required for this is relatively low, because a high force transmission in the manner of a toggle joint is achieved by pivoting the articulated struts.
- the sealing cap can therefore be applied with relatively little force; she
- in the closed state it is such a rigid structure that it can only be detached after it has been destroyed.
- the two expansion struts engage with at least one locking element projecting from the cover surface.
- the spreading struts are securely held in their locking position in the closed state even when the sealing cap is deformed by external forces.
- a second embodiment of the invention it is provided for locking screws, in the recess of which two laterally open eyelets are arranged, that two anchoring tongues connected to the cover surface and extending at a distance parallel thereto are provided as anchoring elements, which are turned laterally by a rotary movement of the sealing cap the eyelets are insertable, and that the anchoring tongues have barbs engaging behind the eyelets at their free ends.
- the anchoring elements have at least two locking hooks projecting downward from the cover surface are that snap elastically and positively behind opposite undercuts of the locking screw.
- the sealing cap is connected to the screw plug by simply pressing it on until the locking hooks snap behind the undercuts. Since this is a form-fitting connection, loosening is only possible if the sealing cap is destroyed.
- the sealing cap 1 shown in FIGS. 1-3 is made in one piece from plastic and is intended for connection to a screw plug 2 of a safety closure of a liquid container, in particular a safety closure according to DIN 6643 for a steel bung container.
- the screw plug 2 has an upwardly open recess 3 with an edge 4 on which an external thread 5 is formed.
- grooves 6 are formed on the inner edge, which represent undercuts.
- the sealing cap 1 has an essentially flat cover surface 7 which covers the screw plug 2 and which merges into a cap edge 8 which overlaps the edge of the safety closure.
- two anchoring flaps 9 protrude downward at opposite points, each of which is articulated to the cover surface 7 via a thin hinge web 10.
- the two anchoring flaps 9 each have a plurality of anchor teeth 11 on their outside.
- the two anchoring flaps 9 are connected to one another by two diametrically arranged expansion struts 12.
- Each expansion strut 12 is connected in an articulated manner to the associated anchoring flap 9 via a hinge web 13.
- the two expansion struts 12 are connected to one another by a joint web 14.
- the joint formed by the joint web 14 lies at the lowest point of the expansion struts 12, ie the two Spreading struts 12 extend from the hinge webs 14 in a flat V-shaped arrangement obliquely upwards to the two anchoring flaps 10, which are pivoted inwards with respect to the vertical.
- the sealing cap 1 can be placed on the screw plug 2, as shown in Fig. 1.
- the two expansion struts 12 are supported on the bottom of the recess 3 on a sheet metal strip 2a which is usually provided there. If the sealing cap 1 is now pressed by pressure or impact from above onto the locking screw 2, the inner ends of the expansion struts 12 are pressed into the position shown in FIG. 2 up to their horizontal position. The expansion struts 12 spread the two flaps 9 apart into the vertical position shown.
- their anchor teeth 11 are pressed into the grooves 6 on the inner edge of the locking screw 2 and form a positive locking connection there.
- Each expansion strut 12 has a rib 16 on its upper side, which is supported at its outer end by a projection 17 in the closed state (FIG. 2) on the inside of the anchoring flap 9 which is connected in an articulated manner.
- the anchoring flap is held stable in its position in which the anchor teeth 11 engage in the grooves 6.
- a latching web 18 connected to the lid surface 7 forms a latching element projecting downward from the lid surface 7, which engages with the two expanding struts 12 in the closed state.
- the latching web 18 is essentially arrow-shaped at its lower end in cross section and has a latching edge 19 on both sides, which in the closed state (FIG. 2) is engaged behind by a latching hook 20, which is connected to the associated expansion strut 12 and is designed as an upper projection of the rib 16.
- the locking web 18 forms with its lower end a stop for the inner ends of the two expansion struts 12. This prevents the expansion struts 12 from moving further upward after their extended position has been exceeded. As shown in FIG. 2, in the closed state of the sealing cap, the expansion struts 12 remain in an essentially extended position in which the two anchoring flaps 9 are supported in a stable manner. The stop formed by the locking web 18 prevents the spreading struts from moving upward in the closed state.
- the latching web 18 is connected to a tear tab 21 which is delimited in the cover surface 7 by lines of weakness 22.
- the tear tab 21 can be gripped on a grip tongue 23 and pulled up.
- the expansion struts 12 are released and the sealing cap 1, which has been destroyed along the weakening lines 22, can be removed.
- a plurality of projecting cams 24 are provided which are supported on the upper edge of the locking screw 2 and which ensure that the top of the safety lock is ventilated.
- the sealing cap 1 'shown in FIGS. 4 and 5 is intended for connection with a screw plug 2, in particular a screw plug according to DIN 6643, which has two laterally open eyelets 25 in its recess 3.
- two anchoring tongues 26 are provided as anchoring elements, which are integrally connected at one end 26a to the cover surface 7 of the sealing cap 1 '.
- the anchoring tongues 26 extend on a circular arc section concentrically to the center of the sealing cap 1 'at a distance parallel to the cover surface 7. They lie on a diameter which corresponds to the distance between the two eyelets 25.
- each anchoring tongue 26 is laterally inserted into the associated eyelet 25 by a rotary movement, which is indicated by an arrow 27 in FIG. 5.
- the anchoring tongues 26 each have an inwardly directed barb 28. These barbs 28 engage behind the eyelets 25 at the end of the rotational movement and prevent the sealing cap 1 'from rotating back.
- the sealing cap can only be opened by violent destruction.
- FIGS. 6 and 7. A further modified embodiment of a sealing cap 1 ′′ is shown in FIGS. 6 and 7.
- at least two, in the exemplary embodiment shown four latching hooks 29 project downward from the cover surface 7.
- These latching hooks 29 engage elastically and positively behind opposite undercuts 25a on the edge of the eyelets 25 of the locking screw 2.
- the locking hooks 29 also prevent the sealing cap 1 ′′ from rotating, so that it is not possible to bring the locking hooks 29 out of engagement with the undercuts 25a by rotation.
- the sealing cap 1 ' is centered the screw plug 2 is appropriate.
- centering projections 30 projecting downward from the cover surface 7 are provided in the form of cylindrical sections which run concentrically to the peripheral edge of the sealing cap 1 ′′ and which center the sealing cap 1 ′′ on the inner edge of the locking screw 2.

Abstract
Description
Die Erfindung betrifft eine Siegelkappe für einen Sicherheitsverschluß. Gattungsgemäße Siegelkappen aus Kunststoff sind durch die DE-A's 36 37 644 und 33 15 548 bekanntgeworden.The invention relates to a sealing cap for a security lock. Generic sealing caps made of plastic have become known from DE-A's 36 37 644 and 33 15 548.
Aufgabe der Erfindung ist es daher, eine Siegelkappe der eingangs genannten Gattung zu schaffen, die in einfacher Weise aufgebracht werden kann.The object of the invention is therefore to provide a sealing cap of the type mentioned, which can be applied in a simple manner.
Diese Aufgabe wird erfindungsgemäß durch die Merkmale der Kennzeichenteile der unabhängigen Patentansprüche gelöst, die verschiedene Ausführungsformen der Siegelkappe definieren. Da die einrastende Verbindung zwischen der Siegelkappe und der Verschlußschraube innerhalb der Ausnehmung der Verschlußschraube und nicht am äußeren Rand des Sicherheitsverschlusses erfolgt, ist diese Verbindungsstelle nach dem Einrasten nicht mehr von außen zugänglich, so daß eine nachträgliche Manipulation, insbesondere ein Öffnen des Verschlusses ohne Zerstörung der Siegelkappe nicht mehr möglich ist. Damit sind die Anforderungen an einen Originalitätsverschluß gegeben.This object is achieved according to the invention by the features of the characterizing parts of the independent claims, which define different embodiments of the sealing cap. Since the locking connection between the sealing cap and the locking screw takes place within the recess of the locking screw and not on the outer edge of the security lock, this connection point is no longer accessible from the outside after snapping in, so that subsequent manipulation, in particular opening the lock without destroying the Sealing cap is no longer possible. This means that the requirements for a tamper-evident seal are met.
Gemäß einer ersten Ausführungsform der Erfindung ist bei Verwendung einer Verschlußschraube, die am Innenrand ihrer Ausnehmung mindestens eine umlaufende Rille aufweist, vorgesehen, daß als Verankerungselement zwei gelenkig mit der Deckelfläche verbundene Verankerungsklappen nach unten ragen, die jeweils an ihrer Außenkante in die umlaufende Rille am Innenrand der Verschlußschraube eingreifende Ankerzähne aufweisen, und daß die beiden Verankerungsklappen durch zwei sich am Boden der Ausnehmung der Verschlußschraube abstützende, gelenkig miteinander verbundene Spreizstreben miteinander verbunden sind.According to a first embodiment of the invention, when using a locking screw which has at least one circumferential groove on the inner edge of its recess, it is provided that two are articulated as an anchoring element the anchoring flaps connected to the cover surface project downward, each having on their outer edge in the circumferential groove on the inner edge of the locking screw engaging anchoring teeth, and that the two anchoring flaps are connected to one another by two articulated bracing struts which are supported on the bottom of the recess of the locking screw.
Eine solche umlaufende Rille ist üblicherweise am Innenrand der Ausnehmung der Verschlußschrauben schon durch die Herstellung des Außengewindes der Verschlußschraube gebildet, so daß diese Rille oder mehrere Rillen, als Hinterschneidungen für die Verankerung der Siegelkappe genutzt werden können.Such a circumferential groove is usually already formed on the inner edge of the recess of the locking screw by the production of the external thread of the locking screw, so that this groove or several grooves can be used as undercuts for anchoring the sealing cap.
Durch die Verbindung der beiden schwenkbar an der Deckelfläche angebrachten Verankerungsklappen durch die gemeinsamen Spreizstreben wird erreicht, daß die beiden Verankerungsklappen in ihrer Verankerungsstellung mit großer Steifigkeit festgehalten werden, weil sich die beiden Verankerungsklappen über die Spreizstreben diagonal gegeneinander abstützen. Infolge des formschlüssigen Eingriffs der Ankerzähne der Verankerungsklappen an den Hinterschneidungen der Verschlußschraube kann die Siegelkappe, die im verschlossenen Zustand ein in sich weitgehend formsteifes Bauteil darstellt, nur nach Zerstörung gelöst werden. Die Anforderungen an einen Originalitätsverschluß sind daher in hohem Maße erfüllt.The connection of the two anchoring flaps pivotally attached to the cover surface by the common expansion struts ensures that the two anchoring flaps are held in place in their anchoring position with great rigidity because the two anchoring flaps are supported diagonally against one another via the expansion struts. As a result of the positive engagement of the anchor teeth of the anchoring flaps on the undercuts of the locking screw, the sealing cap, which in the closed state is a largely rigid component in itself, can only be released after destruction. The requirements for a tamper-evident closure are therefore met to a high degree.
Das Aufsetzen der Siegelkappe erfolgt in einfacher Weise durch Druck oder Schlag von oben. Die hierfür benötigte Kraft ist verhältnismäßig gering, weil durch die Schwenkung der gelenkig miteinander verbundenen Spreizstreben eine hohe Kraftübersetzung nach Art eines Kniehebelgelenks erzielt wird. Die Siegelkappe kann daher mit verhältnismäßig geringer Kraft aufgebracht werden; sie stellt im verschlossenen Zustand jedoch ein in sich so formsteifes Gebilde dar, daß sie nur nach Zerstörung gelöst werden kann.The sealing cap is put on in a simple manner by pressure or impact from above. The force required for this is relatively low, because a high force transmission in the manner of a toggle joint is achieved by pivoting the articulated struts. The sealing cap can therefore be applied with relatively little force; she However, in the closed state it is such a rigid structure that it can only be detached after it has been destroyed.
Die beiden Spreizstreben stehen im geschlossenen Zustand mit mindestens einem von der Deckelfläche vorspringenden Rastelement in Eingriff. Dadurch werden die Spreizstreben im geschlossenen Zustand auch dann sicher in ihrer Verriegelungsstellung gehalten, wenn durch äußere Kräfte eine Verformung der Siegelkappe erfolgt.In the closed state, the two expansion struts engage with at least one locking element projecting from the cover surface. As a result, the spreading struts are securely held in their locking position in the closed state even when the sealing cap is deformed by external forces.
Gemäß einer zweiten Ausführungsform der Erfindung ist für Verschlußschrauben, in deren Ausnehmung zwei seitlich offene Ösen angeordnet sind, vorgesehen, daß als Verankerungselemente zwei mit der Deckelfläche verbundene und sich im Abstand parallel zu dieser erstreckende Verankerungszungen vorgesehen sind, die durch eine Drehbewegung der Siegelkappe seitlich in die Ösen einführbar sind, und daß die Verankerungszungen an ihren freien Enden die Ösen hintergreifende Widerhaken aufweisen.According to a second embodiment of the invention, it is provided for locking screws, in the recess of which two laterally open eyelets are arranged, that two anchoring tongues connected to the cover surface and extending at a distance parallel thereto are provided as anchoring elements, which are turned laterally by a rotary movement of the sealing cap the eyelets are insertable, and that the anchoring tongues have barbs engaging behind the eyelets at their free ends.
Solche seitlich offenen Ösen sind an den herkömmlichen Verschlußschrauben ohnehin vorgesehen. Die Verbindung mit der Siegelkappe erfolgt durch eine einfache Drehbewegung, bis die Verankerungszungen so weit in die Ösen eingesteckt sind, daS die Widerhaken an den Ösen einrasten. Eine Rückdrehbewegung zum Öffnen der Siegelkappe wird dadurch formschlüssig verhindert, so daß die Siegelkappe beim Öffnen zerstört werden muß.Such laterally open eyelets are provided on the conventional locking screws anyway. The connection with the sealing cap is made by a simple rotary movement until the anchoring tongues are inserted into the eyelets until the barbs snap into place on the eyelets. A backward rotation to open the sealing cap is thereby positively prevented, so that the sealing cap must be destroyed when opening.
Gemäß einer dritten Ausführung der Erfindung ist vorgesehen, daß die Verankerungselemente mindestens zwei von der Deckelfläche nach unten vorspringende Rasthaken sind, die elastisch und formschlüssig hinter gegenüberliegende Hinterschneidungen der Verschlußschraube einrasten.According to a third embodiment of the invention it is provided that the anchoring elements have at least two locking hooks projecting downward from the cover surface are that snap elastically and positively behind opposite undercuts of the locking screw.
Die Verbindung der Siegelkappe mit der Verschlußschraube erfolgt hierbei durch einfaches Aufdrücken, bis die Rasthaken hinter den Hinterschneidungen einrasten. Da es sich um eine formschlüssige Verbindung handelt, ist auch hier ein Lösen nur unter Zerstörung der Siegelkappe möglich.The sealing cap is connected to the screw plug by simply pressing it on until the locking hooks snap behind the undercuts. Since this is a form-fitting connection, loosening is only possible if the sealing cap is destroyed.
Weitere vorteilhafte Ausgestaltungen des Erfindungsgedankens sind Gegenstand der Unteransprüche.Further advantageous embodiments of the inventive concept are the subject of the dependent claims.

Die in den Fig. 1-3 dargestellte Siegelkappe 1 ist einstückig aus Kunststoff hergestellt und ist zur Verbindung mit einer Verschlußschraube 2 eines Sicherheitsverschlusses eines Flüssigkeitsbehälters bestimmt, insbesondere eines Sicherheitsverschlusses nach DIN 6643 für einen Spundbehälter aus Stahl.The sealing
Die Verschlußschraube 2 weist eine nach oben offene Ausnehmung 3 mit einem Rand 4 auf, an dem ein Außengewinde 5 ausgebildet ist. Bei der Herstellung des Außengewindes 5 an der aus Blech geformten Verschlußschraube 2 entstehen am Innenrand Rillen 6, die Hinterschneidungen darstellen.The
Die Siegelkappe 1 weist eine die Verschlußschraube 2 überdeckende, im wesentlichen ebene Deckelfläche 7 auf, die in einen den Rand des Sicherheitsverschlusses übergreifenden Kappenrand 8 übergeht.The sealing
Von der Deckelfläche 7 springen an einander gegenüberliegenden Stellen zwei Verankerungsklappen 9 nach unten vor, die mit der Deckelfläche 7 jeweils über einen dünnen Gelenksteg 10 gelenkig verbunden sind.From the
Die beiden Verankerungsklappen 9 weisen jeweils an ihrer Außenseite mehrere Ankerzähne 11 auf. Die beiden Verankerungsklappen 9 sind durch zwei diametral angeordnete Spreizstreben 12 miteinander verbunden. Jede Spreizstrebe 12 ist über einen Gelenksteg 13 gelenkig mit der zugeordneten Verankerungsklappe 9 verbunden. In der Mitte der Siegelkappe 1 sind die beiden Spreizstreben 12 miteinander durch einen Gelenksteg 14 verbunden. Das durch den Gelenksteg 14 gebildete Gelenk liegt in dem in Fig. 1 dargestellten Ausgangszustand der Siegelkappe 1 am untersten Punkt der Spreizstreben 12, d.h. die beiden Spreizstreben 12 erstrecken sich von den Gelenkstegen 14 in flacher V-förmiger Anordnung schräg nach oben zu den beiden Verankerungsklappen 10, die gegenüber der Senkrechten nach innen geschwenkt sind.The two
In dieser Stellung kann die Siegelkappe 1 auf die Verschlußschraube 2 aufgesetzt werden, wie in Fig. 1 dargestellt ist. Mit ihren beiden inneren Enden, an denen jeweils ein unterer Stützwulst 15 vorgesehen ist, stützen sich die beiden Spreizstreben 12 am Boden der Ausnehmung 3 an einem dort üblicherweise angebrachten Blechstreifen 2a ab. Wenn die Siegelkappe 1 nun durch Druck oder Schlag von oben auf die Verschlußschraube 2 gedrückt wird, werden die inneren Enden der Spreizstreben 12 bis über ihre horizontale Stellung in die in Fig. 2 gezeigte Stellung gedrückt. Die Spreizstreben 12 spreizen dabei die beiden Verschlußklappen 9 auseinander bis in die dargestellte senkrechte Stellung. Zugleich werden deren Ankerzähne 11 in die Rillen 6 am Innenrand der Verschlußschraube 2 eingedrückt und bilden dort eine formschlüssige Rastverbindung.In this position, the
Jede Spreizstrebe 12 weist an ihrer Oberseite eine Rippe 16 auf, die sich an ihrem äußeren Ende mit einem Vorsprung 17 im geschlossenen Zustand (Fig. 2) an der Innenseite der jeweils gelenkig angeschlossenen Verankerungsklappe 9 abstützt. Dadurch wird die Verankerungsklappe stabil in ihrer Stellung gehalten, in der die Ankerzähne 11 in die Rillen 6 eingreifen.Each
Ein mit der Deckelfläche 7 verbundener Raststeg 18 bildet ein von der Deckelfläche 7 nach unten vorspringendes Rastelement, das im geschlossenen Zustand mit den beiden Spreizststreben 12 in Rasteingriff tritt.A
Hierzu ist der Raststeg 18 an seinem unteren Ende im Querschnitt im wesentlichen pfeilförmig ausgebildet und weist beiderseits eine Rastkante 19 auf, die im geschlossenen Zustand (Fig. 2) von jeweils einem Rasthaken 20 hintergriffen wird, der mit der zugeordneten Spreizstrebe 12 verbunden und als oberer Vorsprung der Rippe 16 ausgeführt ist.For this purpose, the
Zugleich bildet der Raststeg 18 mit seinem unteren Ende einen Anschlag für die inneren Enden der beiden Spreizstreben 12. Dadurch wird verhindert, daß sich die Spreizstreben 12 nach Überschreiten ihrer gestreckten Stellung weiter nach oben bewegen. Wie die Fig. 2 zeigt, bleiben die Spreizstreben 12 im geschlossenen Zustand der Siegelkappe in einer im wesentlichen gestreckten Stellung, in der eine stabile Abstützung der beiden Verankerungsklappen 9 erfolgt. Der vom Raststeg 18 gebildete Anschlag verhindert eine Bewegung der Spreizstreben nach oben im geschlossenen Zustand.At the same time, the
Der Raststeg 18 ist mit einer Aufreißlasche 21 verbunden, die in der Deckelfläche 7 durch Schwächungslinien 22 umgrenzt ist. Zum Öffnen des Verschlusses kann die Aufreißlasche 21 an einer Griffzunge 23 erfaßt und hochgerissen werden. Dadurch werden die Spreizstreben 12 freigegeben, und die Siegelkappe 1, die entlang der Schwächungslinien 22 zerstört ist, kann abgenommen werden.The
An der Unterseite der Deckelfläche 7 sind mehrere vorspringende Nocken 24 vorgesehen, die sich am oberen Rand der Verschlußschraube 2 abstützen und die dafür sorgen, daß die Oberseite des Sicherheitsverschlusses belüftet wird.On the underside of the
Die in den Fig. 4 und 5 dargestellte Siegelkappe 1' ist zur Verbindung mit einer Verschlußschraube 2 bestimmt, insbesondere einer Verschlußschraube nach DIN 6643, die in ihrer Ausnehmung 3 zwei seitlich offene Ösen 25 aufweist.The sealing cap 1 'shown in FIGS. 4 and 5 is intended for connection with a
Als Verankerungselemente sind hierbei zwei Verankerungszungen 26 vorgesehen, die an ihrem einen Ende 26a mit der Deckelfläche 7 der Siegelkappe 1' einstückig verbunden sind. Die Verankerungszungen 26 erstrecken sich auf einem Kreisbogenabschnitt konzentrisch zur Mitt der Siegelkappe 1' im Abstand parallel zur Deckelfläche 7. Sie liegen auf einem Durchmesser, der dem Abstand der beiden Ösen 25 entspricht.In this case, two anchoring
Nach dem Aufsetzen der Siegelkappe 1' wird durch eine Drehbewegung, die in Fig. 5 mit einem Pfeil 27 angedeutet ist, jede Verankerungszunge 26 in die zugeordnete Öse 25 seitlich eingeführt. An ihren freien Enden weisen die Verankerungszungen 26 jeweils einen nach innen gerichteten Widerhaken 28 auf. Diese Widerhaken 28 greifen am Ende der Drehbewegung hinter die Ösen 25 und verhindern eine Rückdrehbewegung der Siegelkappe 1'. Die Siegelkappe kann nur durch gewaltsame Zerstörung geöffnet werden.After the sealing cap 1 'has been put on, each anchoring
Eine weitere abgewandelte Ausführungsform einer Siegelkappe 1'' ist in den Fig. 6 und 7 dargestellt. Hierbei springen von der Deckelfläche 7 mindestens zwei, im dargestellten Ausführungsbeispiel vier Rasthaken 29 nach unten vor. Diese Rasthaken 29 rasten elastisch und formschlüssig hinter gegenüberliegenden Hinterschneidungen 25a am Rand der Ösen 25 der Verschlußschraube 2 ein. Die Rasthaken 29 verhindern zugleich eine Drehung der Siegelkappe 1'', so daß es nicht möglich ist, die Rasthaken 29 durch eine Drehung außer Eingriff mit den Hinterschneidungen 25a zu bringen.A further modified embodiment of a
Um ein sicheres Einrasten der Rasthaken 29 zu gewährleisten, ist eine Zentrierung der Siegelkappe 1' an der Verschlußschraube 2 zweckmäßig. Hierzu sind von der Deckelfläche 7 nach unten ragende Zentriervorsprünge 30 in Form von Zylinderabschnitten vorgesehen, die konzentrisch zum Umfangsrand der Siegelkappe 1'' verlaufen und die die Siegelkappe 1'' am Innenrand der Verschlußschraube 2 zentrieren.In order to ensure that the latching hooks 29 engage securely, the sealing cap 1 'is centered the
