Description

Die vorliegende Erfindung betrifft eine Siegelkappe für einen in einen Spundstutzen eines Behälters eingesetzten Behälterstopfen, wobei die Siegelkappe eine Deckelscheibe mit einem Befestigungsring aufweist, der mit einer Unterseite der Deckelscheibe verbunden ist, wobei der Befestigungsring eine Rasteinrichtung zur Herstellung einer lösbaren Eingriffsverbindung mit einer an einer Innenwand einer Stopfenmulde des Spundstopfens ausgebildeten Gegenrasteinrichtung aufweist, wobei die Deckelscheibe an ihrem Umfang eine konzentrisch zum Befestigungsring angeordnete Randschürze zur Überdeckung eines Öffnungsrands des Spundstutzens aufweist.The present invention relates to a sealing cap for a container plug inserted into a bung of a container, wherein the sealing cap has a cover plate with a fixing ring which is connected to a bottom of the cover plate, wherein the fastening ring a locking device for producing a releasable engagement connection with one on an inner wall Having a stopper recess of the bung stopper formed counter-locking device, wherein the cover disc has at its periphery a concentric with the mounting ring arranged edge skirt for covering an opening edge of the bung nozzle.

Eine Siegelkappe der eingangs genannten Art ist aus der EP 2 144 821 B1 bekannt. Die bekannte Siegelkappe ist so ausgestaltet, dass bei einer Entfernung der Siegelkappe von dem in den Spundstutzen eingesetzten Spundstopfen die Verbindung zwischen der Deckelscheibe und der Randschürze zerstört werden soll, um eine Manipulation an der Siegelkappe von außen sichtbar zu machen. Der Spundstutzen weist einen radial nach außen vorspringender Sicherungswulst auf, der unmittelbar unterhalb einer Unterkante der Randschürze angeordnet ist und der ein Untergreifen der Randschürze, derart, dass ohne die Verwendung besonderer Hilfsmittel die Randschürze ohne Zerstörung angehoben und so die Siegelkappe von dem Spundstutzen entfernt werden könnte, verhindern soll. Dieser Sicherungswulst erschwert sicherlich das vorstehend erläuterte Untergreifen der Randschürze, wobei jedoch immer noch ein Ringspalt zwischen der Unterkante der Randschürze und dem Sicherungswulst verbleibt, der das Eindringen einer Messerklinge oder dergleichen in den Ringspalt und damit das Untergreifen der Randschürze ermöglicht. Aus der DE102009022800 B3 ist eine Siegelkappe gemäß dem Oberbegriff des Anspruchs 1 bekannt.A sealing cap of the type mentioned is from the EP 2 144 821 B1 known. The known sealing cap is designed so that when removing the sealing cap from the bung plug inserted into the bung the connection between the cover plate and the skirt should be destroyed to make a manipulation of the seal cap visible from the outside. The bung has a radially outwardly projecting Sicherungswulst, the immediate is arranged below a lower edge of the skirt and the underreaching the skirt, such that without the use of special tools raised the skirt without destruction and so the sealing cap could be removed from the bung prevents. This securing bead certainly complicates the above-mentioned engaging under the edge skirt, but still remains an annular gap between the lower edge of the skirt and the backup bead, which allows the penetration of a knife blade or the like in the annular gap and thus under reaching the skirt. From the DE102009022800 B3 a sealing cap according to the preamble of claim 1 is known.

Aus der EP 1 692 046 B1 ist eine Siegelkappe für einen in einen Spundstutzen eines Behälters eingesetzten Behälterstopfen bekannt, die, wie die vorstehend erläuterte, aus der EP 2 144 821 B1 bekannte Siegelkappe, eine an einer Deckelscheibe angeordnete Randschürze zur Überdeckung eines Öffnungsrands des Spundstutzens aufweist. Bei dieser Siegelkappe ist die Randschürze so ausgebildet, dass die Unterkante der Randschürze auf einem am Spundstutzen ausgebildeten Stützbund aufliegt, sodass zwischen der Unterkante der Randschürze und dem Stützbund kein Spalt verbleibt, in den eine Messerklinge oder dergleichen eingreifen könnte, um die Siegelkappe ohne Zerstörung vom Spundstutzen abzuheben.From the EP 1 692 046 B1 is a sealing cap for a container plug inserted into a bung of a container known, which, as explained above, from the EP 2 144 821 B1 has known seal cap, arranged on a cover disc edge skirt for covering an opening edge of the bung. In this sealing cap, the skirt is formed so that the lower edge of the edge skirt rests on a formed on the bung neck support collar so that no gap remains between the lower edge of the skirt and the support collar, in which a knife blade or the like could engage to seal the seal without destruction Remove the bung.

Durch die vorstehend erläuterte Ausgestaltung der Siegelkappe kann zwar verhindert werden, dass eine Manipulation an der Siegelkappe unbemerkt bleibt. Allerdings kann nicht ausgeschlossen werden, dass die Ausgestaltung der Siegelkappe, derart, dass die Randschürze mit ihrer Unterkante auf dem Stützbund des Spundstutzens aufliegt, den Vorgang des Verrastens einer Rasteinrichtung der Siegelkappe, die an einem Befestigungsring der Siegelkappe ausgebildet ist und deren Unterkante sich in einer Ebene mit der Unterkante der Befestigungsschürze befindet, behindert. Dies gilt insbesondere dann, wenn Verunreinigungen oder dergleichen auf dem Stützbund des Spundstutzens abgelagert sind, die den Kontakt der Unterkanten der Randschürze und der Befestigungshülse mit dem Stützbund verhindern, sodass ein vollständiges Verrasten der Rasteinrichtung nicht möglich ist.By the above-described embodiment of the sealing cap can indeed be prevented that a manipulation on the sealing cap goes unnoticed. However, it can not be ruled out that the design of the sealing cap, such that the edge skirt rests with its lower edge on the support collar of the bung, the process of ratcheting a locking device of the sealing cap, which is formed on a mounting ring of the sealing cap and the lower edge in a Level with the lower edge of the mounting skirt is obstructed. This is especially true when contaminants or the like are deposited on the support collar of the bung, the contact of the lower edges of the skirt and the mounting sleeve prevent with the support collar, so that a complete locking of the locking device is not possible.

Der vorliegenden Erfindung liegt daher die Aufgabe zugrunde, eine Siegelkappe vorzuschlagen, die einen erhöhten Schutz gegen Manipulationen aufweist, ohne dass die sichere Rastverbindung zwischen der Siegelkappe und dem Spundstopfen beeinträchtigt wird.The present invention is therefore based on the object to propose a sealing cap, which has an increased protection against tampering, without the secure locking connection between the sealing cap and the bung stopper is impaired.

Zur Lösung dieser Aufgabe weist die erfindungsgemäße Siegelkappe die Merkmale des Anspruchs 1 auf.To solve this problem, the sealing cap according to the invention has the features of claim 1.

Erfindungsgemäß weist der Befestigungsring zwischen der Deckelscheibe und der Rasteinrichtung in einem Stützabstand zur Rasteinrichtung eine Stützeinrichtung zur Abstützung des Befestigungsrings gegen die Innenwand der Stopfenmulde auf.According to the invention, the fastening ring between the cover disc and the latching device in a support distance to the latching device on a support means for supporting the mounting ring against the inner wall of the plug well.

Aufgrund der Abstützung des Befestigungsrings gegen die Innenwand der Stopfenmulde wird die freie Verformung des Befestigungsrings innerhalb der Stopfenmulde behindert. Dies führt zu einer Versteifung des Befestigungsrings, sodass ein Aufbiegen und Abhebeln der Siegelkappe mittels einer in einen unterhalb der Unterkante der Randschürze eingeführten Klinge oder dergleichen erschwert wird.Due to the support of the mounting ring against the inner wall of the plug well, the free deformation of the mounting ring is hindered within the plug well. This leads to a stiffening of the fastening ring, so that bending and prying off of the sealing cap by means of a blade inserted into a below the lower edge of the edge skirt or the like is made more difficult.

Wenn gemäß einer bevorzugten Ausführungsform die Randschürze durch eine Sollbrucheinrichtungen aufweisende Randschürzen-Sollbruchlinie von der Deckelscheibe abgeteilt ist, können die bei dem Versuch, mittels einer in einen unterhalb der Unterkante der Randschürze eingeführten Klinge oder dergleichen die Siegelkappe vom Spundstutzen abzuhebeln, von der Randschürze über die Sollbrucheinrichtungen der Randschürzen-Sollbruchlinie auf die Deckscheibe übertragenen Kräfte aufgrund der Stützeinrichtung nicht durch eine ausreichende Verformung des Befestigungsrings aufgenommen werden, sondern führen zu einer Zerstörung der Sollbrucheinrichtungen. Mit der vorgenannten Versteifung des Befestigungsrings durch Abstützung des Befestigungsrings an der Innenwand der Stopfenmulde wird also in dem Fall, dass Sollbrucheinrichtungen zwischen der Randschürze und der Deckelscheibe vorgesehen werden, die Auslöseempfindlichkeit der Sollbrucheinrichtungen reduziert, sodass bereits vergleichbar geringe Kräfte, die auf die Randschürze wirken, und die bei einem nicht erfindungsgemäß versteiften Befestigungsring keine Zerstörung der Sollbrucheinrichtungen herbeiführen würden, eine Zerstörung der Sollbrucheinrichtungen bewirken.If, according to a preferred embodiment, the skirting is divided by a predetermined breaking devices having edge apron break line of the cover plate, which in the attempt to pry by means of an inserted into a below the lower edge of the skirt apron blade or the like to pry the sealing cap from the bung, from the edge skirt over the Due to the support device predetermined breaking devices of the apron rupture line on the cover plate transmitted forces are not absorbed by a sufficient deformation of the mounting ring, but lead to a destruction of the predetermined breaking devices. With the aforementioned stiffening of the mounting ring by supporting the mounting ring on the inner wall Thus, in the case that predetermined breaking devices are provided between the skirt and the cover disc, the plug depression reduces the triggering sensitivity of the predetermined breaking devices, so that even comparatively small forces acting on the skirting edge and the fastening ring not stiffened according to the invention do not destroy the predetermined breaking devices would cause destruction of the breaking devices.

Trotz dieser Erhöhung der Auslöseempfindlichkeit der Sollbrucheinrichtungen wird ein sicheres Verrasten der Siegelkappe mit dem Spundstopfen bei der Montage der Siegelkappe nicht beeinträchtigt.Despite this increase in the tripping sensitivity of the predetermined breaking devices, a reliable locking of the sealing cap with the bung plug during assembly of the sealing cap is not impaired.

Wenn die Stützeinrichtung an einem der Deckelscheibe benachbarten axialen Endbereich des Befestigungsrings und die Rasteinrichtung an einem freien Endbereich des Befestigungsrings ausgebildet ist, wir eine möglichst breite Stützbasis zur Abstützung des Befestigungsrings geschaffen.If the support device is formed on an axial end region of the fastening ring adjacent to the cover disk and the latching device is formed on a free end region of the fastening ring, we provide the widest possible support base for supporting the fastening ring.

Vorzugsweise ist die Stützeinrichtung auf etwa 2/3 der Höhe des Befestigungsrings im axialen Endbereich des Befestigungsrings angeordnet, so dass eine breite Stützbasis zur Aufnahme eines auf den Befestigungsring bei dem Versuch des Abhebelns wirkenden Biegemoments geschaffen wird.Preferably, the support means is arranged at about 2/3 of the height of the mounting ring in the axial end region of the mounting ring so as to provide a wide support base for receiving a bending moment acting on the mounting ring in the attempt to pry off.

Bei einer vorteilhaften Ausführungsform erstreckt sich die Stützeinrichtung zumindest abschnittsweise über den Umfang des Befestigungsrings. Da die in dem Spundstutzen eingesetzten Behälterstopfen in der Regel in die Stopfenmulde radial hineinragende, segmentartig ausgebildete Vorsprünge als Widerlager für ein zur Montage der Spundstopfen verwendetes Werkzeug aufweisen, ist es ausreichend, wenn die Stützeinrichtung abschnittsweise, also auch segmentartig über den Umfang des Befestigungsrings ausgebildet ist, um eine Abstützung des Befestigungsrings an den die Innenwand der Stopfenmulde mitausbildenden Vorsprüngen zu ermöglichen. Insbesondere ermöglicht die zumindest abschnittsweise Ausbildung der Stützeinrichtung eine Zentrierung des Befestigungsrings in der Stopfenmulde.In an advantageous embodiment, the support means extends at least in sections over the circumference of the mounting ring. Since the container plugs used in the bung usually have in the plug well radially projecting, segmented projections as an abutment for a tool used for mounting the bung, it is sufficient if the support means sections, so is also formed like a segment over the circumference of the mounting ring to allow support of the mounting ring to the inner wall of the plug well mitbildbildenden projections. In particular, this allows at least sections Training the support means centering the mounting ring in the plug well.

Wenn die Stützeinrichtung als kontinuierlich ausgebildeter Stützsteg ausgebildet ist, also etwa als umlaufende und gegebenenfalls mit Unterbrechungen versehene Anformung, Kante oder Verprägung, insbesondere als umlaufende Reihe von Noppen, in dem Kunststoffmaterial der Siegelkappe ausgebildet ist, kann ein Formwerkzeug, das zur Herstellung der am Befestigungsring mit der Stützeinrichtung versehenen Siegelkappe dient, besonders einfach ausgeführt werden.If the support device is formed as a continuously formed support web, so as a circumferential and possibly intermittent Anformung, edge or embossing, in particular as a circumferential row of knobs, is formed in the plastic material of the sealing cap, a mold, for the preparation of the fastening ring provided with the support device seal cap is very easy to run.

Insbesondere kann ein Formwerkzeug zur Anwendung kommen, das als Schieber ausgebildet ist und dessen Entfernung aus einem Formhohlraum der Form zur Herstellung der Siegelkappe die gleichzeitige Ausbildung des Stützstegs und der Rasteinrichtung am Befestigungsring ermöglicht.In particular, a mold may be used, which is designed as a slide and whose removal from a mold cavity of the mold for producing the sealing cap allows the simultaneous formation of the support web and the locking device on the mounting ring.

Wenn die Stützeinrichtung so ausgebildet ist, dass sie nach Herstellung der Eingriffsverbindung zwischen dem Befestigungsring und der Stopfenmulde an der Innenwand der Stopfenmulde anliegt, wir eine besonders genaue Zentrierung des Befestigungsrings in der Stopfenmulde ermöglicht.If the support means is adapted to abut the inner wall of the plug well after the engagement connection between the fixing ring and the plug well is made, we allow a particularly accurate centering of the fixing ring in the plug well.

In einer besonders vorteilhaften Ausführungsform ist die Rasteinrichtung über eine Verbindungseinrichtung mit einer an der Randschürze angeordneten Zuglasche verbunden ist, wobei die Verbindungseinrichtung einen in der Deckelscheibe ausgebildeten Deckelstreifen aufweist, der durch seitliche, Sollbrucheinrichtungen aufweisende Deckelstreifen-Sollbruchlinien von benachbarten Bereichen der Deckelscheibe abgeteilt ist und einen mit der Rasteinrichtung des Befestigungsrings verbundenen Zugsteg aufweist, wobei sich der Deckelstreifen von der Zuglasche am Umfang der Deckelscheibe in einen zentralen Innenteil der Deckelscheibe innerhalb des Befestigungsrings erstreckt und der Zugsteg in einem Kreuzungsbereich zwischen dem Deckelstreifen und dem Befestigungsring angeordnet ist.In a particularly advantageous embodiment, the latching device is connected via a connecting device with a pull tab arranged on the edge skirt, wherein the connecting device has a cover strip formed in the lid strip, which is divided by lateral, predetermined breaking devices having lid strip lines of weakness of adjacent areas of the lid disc and a with the locking device of the fastening ring connected drawbar, wherein the cover strip extends from the pull tab on the circumference of the cover disc in a central inner part of the cover disc within the mounting ring and the drawbridge is disposed in an intersection between the cover strip and the mounting ring.

Diese besondere Ausführungsform der Siegelkappe bietet nicht nur eine größere Sicherheit gegen Manipulation sondern ermöglicht auch eine besonders leichte reguläre Entfernung der Siegelkappe vom Spundstopfen des Spundstutzens durch eine Öffnungsbewegung, bei der die Zuglasche stets in dieselbe Richtung bewegt wird. Nach einer Zerstörung der Sollbrucheinrichtungen zwischen dem Deckelstreifen und der Deckelscheibe infolge einer schräg nach oben gerichteten Bewegung der Zuglasche wird durch Fortsetzung der Bewegung in dieselbe Richtung über den Deckelstreifen und den Zugsteg zwischen dem Deckelstreifen und dem Befestigungsring aufgrund der Verbindung des Zugstegs mit dem Deckelstreifen in einem Kreuzungsbereich zwischen dem Deckelstreifen und Befestigungsring weiterhin eine Zugkraft auf den Befestigungsring ausgeübt, die den Befestigungsring trotz der versteifend wirkenden Stützeinrichtung des Befestigungsrings nach innen deformiert und ein Lösen der Eingriffverbindung zwischen dem Befestigungsring und dem Behälterverschluss ermöglicht.This particular embodiment of the sealing cap not only provides greater security against manipulation but also allows for particularly easy regular removal of the sealing cap from the bung of the bung by an opening movement in which the pull tab is always moved in the same direction. After destruction of the predetermined breaking devices between the cover strip and the cover plate as a result of an obliquely upward movement of the pull tab is by continuing the movement in the same direction on the cover strip and the drawbridge between the cover strip and the mounting ring due to the connection of the pull bar with the cover strip in one Crossing area between the lid strip and mounting ring further exerted a tensile force on the mounting ring, which deforms the mounting ring in spite of the stiffening acting support means of the mounting ring inside and allows release of the engagement connection between the mounting ring and the container closure.

Dabei wird die zur Entfernung der Siegelkappe benötigte, auf den Befestigungsring wirkende Zugkraft unmittelbar von der Zuglasche auf den Deckelstreifen und von diesem über den Zugsteg auf den Befestigungsring übertragen.In this case, the force required to remove the sealing cap, acting on the mounting ring tensile force is transmitted directly from the pull tab on the cover strip and from this over the drawbridge on the mounting ring.

Vorzugsweise ist der Zugsteg zwischen der Rasteinrichtung und dem Deckelstreifen im Bereich einer im Befestigungsring ausgebildeten Ausnehmung mit der Rasteinrichtung verbunden, so dass die Rasteinrichtung aufgrund der Ausnehmung im Befestigungsring leichter verformbar ist.Preferably, the pull bar between the latching device and the lid strip in the region of a recess formed in the fastening ring is connected to the latching device, so that the latching device is easier to deform due to the recess in the fastening ring.

Besonders vorteilhaft ist es, wenn die Rasteinrichtung angrenzend an einen Anschlussbereich des Zugstegs durch parallel zur Deckelscheibe und seitlich zum Zugsteg verlaufende Rasteinrichtungs-Sollbruchlinien von einer mit der Deckelscheibe verbundenen Ringbasis des Befestigungsrings abgeteilt ist, so dass die Verformbarkeit der Rasteinrichtung gegenüber dem Befestigungsring noch weiter erhöht wird und somit eine Entfernung der Siegelkappe vom Behälterverschluss beziehungsweise ein Lösen des Eingriffs der Rasteinrichtung mit dem Behälterverschluss erleichtert wird.It is particularly advantageous if the latching device is divided adjacent to a connection region of the pull bar by parallel to the cover plate and laterally to the drawbar Rasteinrichtungs-breaking lines of a connected to the cover ring ring base of the mounting ring, so that the deformability of the locking device relative to the mounting ring even further increases becomes and thus one Removal of the sealing cap from the container closure or releasing the engagement of the locking device is facilitated with the container closure.

Wenn der Zugsteg einen parallel zur Deckelscheibe verlaufenden Abschnitt aufweist, der mit der Rasteinrichtung verbunden ist, und einen daran anschließenden, quer zur Deckelscheibe verlaufenden Abschnitt aufweist, der mit einem im Innenteil der Deckelscheibe angeordneten Deckelstreifenabschnitt des Deckelstreifens verbunden ist, wird eine weitestgehend radiale Ausrichtung einer auf die Rasteinrichtung des Befestigungsrings wirkenden Zugkraft ermöglicht, so dass bereits eine relativ geringe Zugkraft zur Trennung der Verbindung zwischen der Rasteinrichtung und dem Behälterverschluss ausreichend ist.When the pull bar has a parallel to the cover disc extending portion which is connected to the latching device, and has a subsequent, transverse to the cover plate extending portion which is connected to a arranged in the inner part of the cover plate cover strip portion of the cover strip, a largely radial alignment of a allows the locking device acting on the locking device tensile force, so that even a relatively low tensile force to separate the connection between the locking device and the container closure is sufficient.

Wenn der Deckelstreifenabschnitt eine gegenüber der Deckelscheibe reduzierte Dicke aufweist, wird gewährleistet, dass die Steifigkeit des Deckelstreifenabschnitts gegenüber der Steifigkeit der Deckelscheibe reduziert ist, so dass die Wirkung der vom Deckelstreifen auf die Rasteinrichtung wirkenden Zugkraft erhöht wird.When the lid strip portion has a thickness reduced with respect to the lid disc, it is ensured that the rigidity of the lid strip portion is reduced from the rigidity of the lid disc, so that the effect of the pulling force acting on the latch means from the lid strip is increased.

Ebenfalls erhöhend auf die Wirkung der Zugkraft bzw. die Steifigkeit der Rasteinrichtung im Anschlussbereich der Rasteinrichtung reduzierend wirkt sich aus, wenn die Rasteinrichtung angrenzend an den Anschlussbereich des Zugstegs und im Bereich der im Befestigungsring ausgebildeten Ausnehmung eine Einkerbung aufweist.Increasing also on the effect of the tensile force or the rigidity of the latching device in the connection region of the latching device has a reducing effect if the latching device has a notch adjacent to the connection region of the tensile web and in the region of the recess formed in the fastening ring.

Vorzugsweise ist die Zuglasche des Deckelstreifens in der Randschürze ausgebildet ist, derart, dass die Zuglasche an seitlichen Sollbrucheinrichtungen mit benachbarten Bereichen der Randschürze verbunden ist.Preferably, the pull tab of the lid strip is formed in the skirt, such that the pull tab is connected to lateral predetermined breaking devices with adjacent areas of the skirt.

Wenn der Befestigungsring mit dem zentralen Innenteil der Deckelscheibe einen Becherteil der Siegelkappe bildet, derart, dass der Innenteil der Deckelscheibe einen in der Deckelscheibe ausgebildeten Becherboden bildet, und der Becherboden von einem Außenteil der Deckelscheibe durch eine kreisförmige Innenteil-Sollbruchlinie abgeteilt ist, wird eine besonders starre Verbindung zwischen der Deckelscheibe und dem Befestigungsring ermöglicht, so dass mittelbar über den Becherboden zwar eine Sollbruchverbindung zwischen dem Befestigungsring und der Deckelscheibe vorgesehen ist, die eine Manipulation an der Siegelkappe dadurch erkennbar macht, dass zusammen mit dem Befestigungsring der Becherboden aus der Deckelscheibe herausgetrennt wird.If the fastening ring with the central inner part of the cover disc forms a cup part of the sealing cap, such that the inner part of the cover disc forms a cup base formed in the cover disc, and the cup bottom of an outer part of the cover disc is divided by a circular inner part-predetermined breaking line, a particularly rigid connection between the cover plate and the mounting ring is made possible so that indirectly via the cup bottom a predetermined breaking connection between the mounting ring and the cover plate is provided, which makes a manipulation of the seal cap thereby recognizable that is separated out of the cover disc together with the mounting ring of the cup bottom.

Anderseits wird über die starre Verbindung zwischen dem Befestigungsring und dem Innenteil der Deckelscheibe eine ausreichend stabile Verbindung zwischen der Deckelscheibe und dem Befestigungsring gegeben ist, um eine unbeabsichtigte Zerstörung der Sollbruchverbindung zwischen dem Befestigungsring und der Deckelscheibe bei der Montage der Siegelkappe zu verhindern.On the other hand, a sufficiently stable connection between the cover plate and the mounting ring is given over the rigid connection between the mounting ring and the inner part of the cover disc to prevent inadvertent destruction of the predetermined breaking connection between the mounting ring and the cover plate during assembly of the sealing cap.

Vorzugsweise sind die Sollbrucheinrichtungen zwischen der Zuglasche und den benachbarten Bereichen der Randschürze im Verhältnis zu der Sollbrucheinrichtung der Randschürzen-Sollbruchlinie so ausgebildet, dass bei einer Trennung der Zuglasche aus der Randschürze die Sollbrucheinrichtung der kreisförmigen Randschürzen-Sollbruchlinie erhalten bleibt.Preferably, the predetermined breaking devices between the pull tab and the adjacent regions of the edge skirt are formed in relation to the predetermined breaking device of the apron predetermined breaking line such that the predetermined breaking device of the circular edge skirt break line is maintained when the pull tab is separated from the skirt.

Weiterhin ist es vorteilhaft, wenn die Sollbrucheinrichtung der Innenteil-Sollbruchlinie im Verhältnis zu einer Sollbrucheinrichtung einer Rasteinrichtungs-Sollbruchlinie so ausgebildet ist, dass bei einer Trennung des Deckelstreifens aus der Deckelscheibe die Sollbrucheinrichtung der Innenteil-Sollbruchlinie erhalten bleibt.Furthermore, it is advantageous if the predetermined breaking device of the inner part predetermined breaking line is designed in relation to a predetermined breaking device of a Rasteinrichtungs breaking line so that when a separation of the cover strip from the cover disc, the predetermined breaking device of the inner part predetermined breaking line is maintained.

Nachfolgend werden eine bevorzugte Ausführungsformen der Siegelkappe anhand der Zeichnung näher erläutert.Hereinafter, a preferred embodiments of the sealing cap will be explained in more detail with reference to the drawing.

In den Fign. 1 und 2 ist eine Siegelkappe 10 dargestellt, die eine Deckelscheibe 11 und eine sich im Wesentlich senkrecht zur Deckelscheibe 11 erstreckende, hülsenförmig ausgebildete Randschürze 12 aufweist, die entlang einer Randschürzen-Sollbruchlinie 13 über Sollbruchstege 14, die zusammen eine Sollbrucheinrichtung 15 ausbilden, mit der Deckelscheibe 11 verbunden ist.In the FIGS. 1 and 2 a sealing cap 10 is shown, which has a cover plate 11 and extending substantially perpendicular to the cover plate 11, sleeve-shaped edge skirt 12 which along an edge skirt break line 13 via predetermined breaking webs 14, which together form a predetermined breaking device 15, connected to the cover plate 11 is.

Wie insbesondere aus Fig. 2 ersichtlich, ist an einer Unterseite 16 der Deckelscheibe 11 ein Befestigungsring 17 an der Deckelscheibe 11 ausgebildet, der mit einem zentralen Innenteil 18 der Deckelscheibe 11 einen Becherteil 19 der Siegelkappe 10 ausbildet, derart, dass der zentrale Innenteil 18 einen integral in der Deckelscheibe ausgebildeten Becherboden des Becherteils 19 bildet. Wie ferner aus Fig. 2 ersichtlich, ist der Innenteil 18 der Deckelscheibe 11 von einem Außenteil 20 der Deckelscheibe 11 durch eine kreisförmige Innenteil-Sollbruchlinie 21 abgeteilt, entlang der eine im vorliegenden Fall durch eine in der Deckelscheibe 11 auf der Unterseite 16 ausgebildete Nut definierte Sollbrucheinrichtung 22 ausgebildet ist.As in particular from Fig. 2 can be seen on a bottom 16 of the cover plate 11, a fastening ring 17 is formed on the cover plate 11, which forms a cup member 19 of the sealing cap 10 with a central inner part 18 of the cover disc 11, such that the central inner part 18 integrally formed in the cover disc cup bottom of the cup part 19 forms. As further out Fig. 2 can be seen, the inner part 18 of the cover plate 11 is separated from an outer part 20 of the cover plate 11 by a circular inner part-predetermined breaking line 21 along which a defined in the present case by a formed in the cover plate 11 on the bottom 16 groove predetermined breaking device 22 is formed.

Die Deckelscheibe 11 weist neben der Aufteilung in einen Innenteil 18 und einen Außenteil 20 einen Deckelstreifen 25 auf, der durch parallel zueinander verlaufende und sich von einem Umfang 26 der Deckelscheibe 11 bis in den Innenteil 18 der Deckelscheibe 11 hinein erstreckende Deckelstreifen-Sollbruchlinien 23, 24 mit Sollbrucheinrichtungen 53, 54 definiert ist. Die Sollbrucheinrichtungen 53, 54 sind im vorliegenden Fall in Übereinstimmung mit der Sollbrucheinrichtung 22 durch in der Unterseite 16 der Deckelscheibe 11 angeordnete Nuten ausgebildet.The cover plate 11 has, in addition to the division into an inner part 18 and an outer part 20, a cover strip 25 which by parallel extending and from a periphery 26 of the cover plate 11 into the inner part 18 of the cover plate 11 extending into cover strip-predetermined breaking lines 23, 24th with predetermined breaking devices 53, 54 is defined. The predetermined breaking devices 53, 54 are formed in the present case in accordance with the predetermined breaking device 22 by arranged in the bottom 16 of the cover plate 11 grooves.

Die Deckelscheibe 11 weist eine an ihrem Umfang 26 angeordnete Zuglasche 27 auf, die über eine den Deckelstreifen 25 und einen mit dem Deckelstreifen 25 verbundenen Zugsteg 28 aufweisende Verbindungseinrichtung 56 mit einer am freien axialen Ende des Befestigungsrings 17 ausgebildeten Rasteinrichtung 29 kraftschlüssig verbunden ist. Der Deckelstreifen 25 erstreckt sich von der am Umfang 26 angeordneten Zuglasche 27 bis in den Innenteil 18 der Deckelscheibe 11 innerhalb des Befestigungsrings 17, wobei der Zugsteg 28 in einem Kreuzungsbereich 57 zwischen dem Deckelstreifen 25 und dem Befestigungsring 17 angeordnet ist.The cover plate 11 has a pull tab 27 arranged on its circumference 26, which is connected in a force-locking manner via a cover strip 25 and a draw web 28 connected to the cover strip 25 connecting device 56 with a locking device 29 formed on the free axial end of the mounting ring. The cover strip 25 extends from the pull tab 27 arranged on the circumference 26 into the inner part 18 of the cover disk 11 within the fastening ring 17, the pull web 28 being arranged in an intersection region 57 between the cover strip 25 and the fastening ring 17.

Wie die Fig. 2 und 3 zeigen, erstreckt sich der Zugsteg 28 im Bereich einer mit der Deckelscheibe 11 verbundenen Ringbasis 52 des Befestigungsrings 17 ausgebildeten Ausnehmung 30, die von der hier ringförmig ausgebildeten Rasteinrichtung 29 bis zur Deckelscheibe 11 reicht. Angrenzend an einen Anschlussbereich 51 des Zugstegs 28 an die Rasteinrichtung 29 sind in dem Befestigungsring 17 parallel zur Deckelscheibe 11 verlaufende und die Rasteinrichtung 29 von der Ringbasis 52 abteilende Rasteinrichtungs-Sollbruchlinien 31, 32 ausgebildet, die im vorliegenden Fall in den Befestigungsring eingebrachte Nuten als Sollbrucheinrichtungen 33, 34 aufweisen.As the Fig. 2 and 3 show, the pull bar 28 extends in the region of a connected to the cover plate 11 ring base 52 of the mounting ring 17 formed recess 30, which extends from the here annular locking device 29 to the cover plate 11. Adjacent to a connection region 51 of the pull bar 28 to the latching device 29 are in the mounting ring 17 parallel to the cover plate 11 extending and the latching device 29 from the annular base 52 dividing Rasteinrichtungs-breaking lines 31, 32 formed, which introduced in the present case in the mounting ring grooves as predetermined breaking devices 33, 34 have.

Wie aus einer Zusammenschau der Fign. 1, 2 und 3 deutlich wird, ist die am Ende des Deckelstreifens 11 ausgebildete Zuglasche 27 in der Randschürze 12 ausgebildet, wobei zwischen der Zuglasche 27 und angrenzenden Bereichen der Randschürze hier durch Sollbruchstege 35, 36 am unteren Rand der Randschürze 12 ausgebildete Sollbrucheinrichtungen vorgesehen sind.As if from a synopsis of FIGS. 1, 2 and 3 becomes clear, the trained at the end of the lid strip 11 pull tab 27 is formed in the skirt 12, wherein between the pull tab 27 and adjacent areas of the skirt are here by breakaway webs 35, 36 provided at the bottom of the skirt 12 trained breaking devices are provided.

Fig. 4 zeigt die auf einem Behälterverschluss 37 angeordnete Siegelkappe 10 während der Montage unmittelbar vor Herstellung eines verrastenden Eingriffs der Rasteinrichtung 29 mit einem an einem Behälterstopfen 38 des Behälterverschlusses 37 ausgebildeten Raststeg 39. Fig. 4 shows the sealing cap 10 arranged on a container closure 37 during assembly immediately before producing a latching engagement of the latching device 29 with a latching web 39 formed on a container plug 38 of the container closure 37.

Der Behälterverschluss 37 ist an einem hier nicht näher dargestellten Kunststoffbehälter ausgebildet und weist einen Spundstutzen 40 auf, der mit einem Innengewinde 41 zur Aufnahme des in den Verschlussstutzen 40 mit seinem Außengewinde 42 eingeschraubten Behälterstopfens 38 dient.The container closure 37 is formed on a plastic container not shown here and has a bung 40, which serves with an internal thread 41 for receiving the screwed into the closure piece 40 with its external thread 42 container stopper 38.

Wie die Fig. 4 zeigt, wird zur Herstellung eines verrastenden Eingriffs der Siegelkappe 10 mit dem Behälterverschluss 37 zunächst die Siegelkappe 10 so auf dem Behälterverschluss 37 angeordnet, dass die an dem Befestigungsring 17 ausgebildete Rasteinrichtung 29 sich axial auf dem Raststeg 39 des Behälterstopfens 38 abstützt. In dieser Relativanordnung der Siegelkappe 10 zum Behälterverschluss 37 ist, wie Fig. 4 zeigt, die an der Deckelscheibe 11 angeordnete Randschürze 12 am Umfang einer am Spundstutzen 40 ausgebildeten Ringwulst 43 angeordnet.As the Fig. 4 shows, to produce a latching engagement of the sealing cap 10 with the container closure 37, the sealing cap 10 is first arranged on the container closure 37, that the latching device 29 formed on the mounting ring 17 is axially supported on the latching web 39 of the container stopper 38. In this relative arrangement of the sealing cap 10 to the container closure 37 is how Fig. 4 show the arranged on the cover plate 11 edge skirt 12 is arranged on the circumference of a formed on the bung 40 annular bead 43.

Die Rasteinrichtung 29 des Befestigungsrings 17 weist einen Außendurchmesser d auf, der im Wesentlichen einem Innendurchmesser D einer mit Werkzeugansätzen 67 versehenen Stopfenmulde 44 des Behälterstopfens 38 entspricht. Die Werkzeugansätze 67 dienen als Widerlager für ein in die Stopfenmulde 44 eingeführtes Montagewerkzeug. Der Innendurchmesser D wird im vorliegenden Fall durch den Abstand von Frontflächen 68 der Werkzeugansätze 67 bestimmt, die eine Innenwand 45 der Stopfenmulde mitausbilden und auf denen die Raststege 39 ausgebildet sind. Bei einer Montage der Siegelkappe 10 auf den Behälterverschluss 37 bilden die Frontflächen 68 eine radiale Führung des Befestigungsrings 17 bis zur Anlage gegen den Raststeg 39 ausbildet. Ausgehend von der in Fig. 4 dargestellten Relativposition der Siegelkappe 10 zu dem Behälterverschluss 37, mit der eine koaxiale Relativanordnung der Siegelkappe 10 zum Behälterverschluss 37 beziehungsweise zum Behälterstopfen 38 definiert ist, kann nun durch Aufbringung einer definierten axialen Montagekraft M eine radiale Verformung des Befestigungsrings 17 mit einem anschließenden Verrasten der Rasteinrichtung 29 des Befestigungsrings 17 hinter dem Raststeg 39, wie in Fig. 5 dargestellt, erfolgen, so dass die Montage der Siegelkappe 10 auf dem Behälterverschluss 37 abgeschlossen ist.The latching device 29 of the fastening ring 17 has an outer diameter d, which essentially corresponds to an inner diameter D of a plug recess 44 provided with tool attachments 67 of the container plug 38. The tool projections 67 serve as an abutment for an inserted into the plug recess 44 assembly tool. The inner diameter D is determined in the present case by the distance from front surfaces 68 of the tool projections 67, which mitausbilden an inner wall 45 of the plug well and on which the locking webs 39 are formed. When mounting the sealing cap 10 on the container closure 37, the front surfaces 68 form a radial guide of the mounting ring 17 until it rests against the detent web 39. Starting from the in Fig. 4 shown relative position of the sealing cap 10 to the container closure 37, with a coaxial relative arrangement of the sealing cap 10 to the container closure 37 and the container stopper 38 is defined, can now by applying a defined axial mounting force M, a radial deformation of the mounting ring 17 with a subsequent locking of the locking device 29th the fastening ring 17 behind the locking bar 39, as in Fig. 5 shown, done so that the assembly of the sealing cap 10 is completed on the container closure 37.

Wie nun aus Fig. 5 ersichtlich wird, überragt in der dargestellten Siegelstellung der Siegelkappe 10 die Randschürze 12 den Ringwulst 43 des Spundstutzens 40, so dass ein unmittelbarer Zugriff auf die Deckelscheibe 11 der Siegelkappe zur Entfernung der Siegelkappe 10 von dem Behälterverschluss 37 nicht möglich ist. Vielmehr kann ein Zugriff auf die Deckelscheibe 11 von der Peripherie der Siegelkappe 10 nur über die Randschürze 12 erfolgen, die längs der Randschürzen-Sollbruchlinie 13 über die Sollbruchstege 14 mit der Deckelscheibe 11 verbunden ist. Ein Versuch mittels einer Krafteinwirkung auf die Randschürze 12 die Deckelscheibe 11 von dem Behälterverschluss 37 zu entfernen führt also zwangsläufig zu einer Zerstörung der Sollbruchstege 14, so dass entsprechende Manipulationen an der Siegelkappe 10 gut erkennbar sind.Like now off Fig. 5 it can be seen, surmounted in the illustrated sealing position of the sealing cap 10, the skirt 12 the annular bead 43 of the bung 40, so that a direct access to the cover plate 11 of the sealing cap for removing the sealing cap 10 of the container closure 37 is not possible. Rather, access to the cover plate 11 from the periphery of the sealing cap 10 can be done only on the edge skirt 12, which is connected along the edge apron breaking line 13 via the predetermined breaking webs 14 with the cover plate 11. An attempt by means of a force on the skirt 12 the To remove cover disk 11 of the container closure 37 thus inevitably leads to a destruction of the predetermined breaking webs 14, so that appropriate manipulations of the sealing cap 10 are clearly visible.

Selbst der Versuch die Siegelkappe 10 durch ein Untergreifen einer Unterkante 69 der Randschürze, beispielsweise durch Einführen einer Messerklinge oder dergleichen in eine zwischen der Unterkante 69 und Spundstutzenbasis 70 ausgebildeten Ringspalt 71, und Ausübung einer Demontagekraft F auf die Randschürze 12 behutsam und mit möglichst geringer Krafteinwirkung ohne Zerstörung der von den Sollbruchstegen 14 ausgebildeten Sollbrucheinrichtungen der Randschürzen-Sollbruchlinie 13 vom Behälterstopfen 38 abzuhebeln, führt wegen der Abstützung der Stützeinrichtung 66 des Befestigungsrings 17 an der Innenwand 45 der Stopfenmulde 44 zu einer Zerstörung der Sollbruchstege 14. Aufgrund der in einem Stützabstand a von der Rasteinrichtung 29 des Befestigungsrings 17 angeordneten Stützeinrichtung 66 wird der Befestigungsring 17 in seiner durch die Demontagekraft F bewirkten Ausweichbewegung behindert. Insbesondere ist die Anordnung der Stützeinrichtung 66 am Befestigungsring 17 so gewählt, dass die Stützeinrichtung 66 auf etwa 2/3 der Höhe h des Befestigungsrings 17 im axialen Endbereich des Befestigungsrings 17 angeordnet ist. Aufgrund der Stützeinrichtung 66 steht der zwischen der Innenwand 45 der Stopfenmulde 44 und dem Befestigungsring ausgebildete Ringraum 70 ( Fig. 4 ) nicht für eine Ausweichbewegung des Befestigungsrings 17 durch Biegung um eine horizontale, im vorliegenden Fall senkrecht zur Zeichenebene verlaufende Biegeachse zur Verfügung. Hierdurch wird der Befestigungsring 17 in seinem Biegeverhalten versteift, so dass bei dem Versuch mittels einer in einen unterhalb der Unterkante 69 der Randschürze 12 eingeführten Klinge oder dergleichen die Siegelkappe 10 vom Spundstopfen abzuhebeln, die dabei von der Randschürze 12 über die Sollbruchstege 14 der Randschürzen-Sollbruchlinie 13 auf die Deckelscheibe 11 übertragene Kraft nicht durch eine ausreichende Verformung des Befestigungsrings 17 aufgenommen wird, sondern auf die Sollbruchstege 14 wirkt, mit der Folge, dass die Sollbruchstege 14 zerstört werden.Even attempting the sealing cap 10 by engaging a lower edge 69 of the skirt, for example by inserting a knife blade or the like in a formed between the lower edge 69 and bung base 70 annular gap 71, and exercise a disassembly F on the skirt 12 gently and with the least possible force without destroying the trained by the breaker bars 14 breaking devices of the edge apron breaking line 13 from the container stopper 38 leads due to the support of the support means 66 of the mounting ring 17 on the inner wall 45 of the plug recess 44 to destruction of the predetermined breaking webs 14. Due to the support distance a of the latching device 29 of the mounting ring 17 arranged support means 66 of the mounting ring 17 is hindered in its caused by the disassembly force F evasive movement. In particular, the arrangement of the support device 66 on the fastening ring 17 is selected such that the support device 66 is arranged at approximately 2/3 of the height h of the fastening ring 17 in the axial end region of the fastening ring 17. Due to the support means 66 of the plug 45 of the hollow between the inner wall 44 is formed and the mounting ring annulus 70 ( Fig. 4 ) not for an evasive movement of the mounting ring 17 by bending about a horizontal, in this case perpendicular to the plane extending bending axis available. As a result, the fastening ring 17 is stiffened in its bending behavior, so that in the attempt by means of an inserted into a below the lower edge 69 of the skirt 12 blade or the like to pry the sealing cap 10 from the bung stopper, the case of the skirt 12 over the predetermined breaking webs 14 of the skirting Rupture line 13 transmitted to the cover disc 11 force is not absorbed by a sufficient deformation of the mounting ring 17, but on the predetermined breaking webs 14 acts, with the result that the predetermined breaking webs 14 are destroyed.

Selbst der Versuch, die Siegelkappe 10 durch unmittelbaren Zugriff von oben zu entfernen ist wegen der eingangs beschriebenen Aufteilung der Deckelscheibe 11 in ein Außenteil 20 und ein Innenteil 18 mittels einer Innenteil-Sollbruchlinie 21 erkennbar, da in diesem Fall die längs der Innenteil-Sollbruchlinie 21 ausgebildete Sollbrucheinrichtung 22 zerstört ist.Even the attempt to remove the sealing cap 10 by direct access from above is recognizable because of the initially described division of the cover plate 11 in an outer part 20 and an inner part 18 by means of an inner part-predetermined breaking line 21, since in this case along the inner part-predetermined breaking line 21st trained breaking device 22 is destroyed.

Zur regulären Öffnung beziehungsweise Demontage der Siegelkappe 10 dient die eingangs bereits beschriebene Zuglasche 27, die mittels der aus dem Deckelstreifen 25 und dem Zugsteg 28 gebildete Verbindungseinrichtung 56 mit der Rasteinrichtung 29 des Befestigungsrings 17 verbunden ist.For regular opening or disassembly of the sealing cap 10 is the pull tab 27 already described above, which is connected by means of the lid strip 25 and the pull bar 28 formed connecting device 56 with the latching device 29 of the mounting ring 17.

Wie Fig. 5 zeigt, ist am Ende der Zuglasche 27 eine hier als ringförmige Öse ausgebildete Griffeinrichtung 46 versehen, die zur Entfernung der Siegelkappe 10 erfasst und mit einer, wie in den Fign. 6-8 dargestellt, schräg nach oben gerichteten, im Wesentlichen linearen Öffnungsbewegung 47 bewegt wird.As Fig. 5 shows, at the end of the pull tab 27 is provided here designed as an annular eyelet grip device 46 which detects the removal of the sealing cap 10 and with a, as in the FIGS. 6-8 shown, obliquely upward, substantially linear opening movement 47 is moved.

Wie Fig. 6 zeigt, werden infolge der Wirkung einer Zugkraft Z auf die Zuglasche 27 zunächst die aus Sollbruchstegen gebildeten Sollbrucheinrichtungen 35 und 36 ( Fig. 3 ) zwischen dem freien Ende der Zuglasche 27 und der Randschürze 12 zerstört. Nachfolgend werden bei weiterhin auf die Zuglasche 27 einwirkender Zugkraft Z die Sollbrucheinrichtungen 53, 54 längs den Deckelstreifen-Sollbruchlinien 23, 24 zerstört, so dass ein erster, radial äußerer Deckelstreifenabschnitt 48, der vom Umfang 26 der Deckelscheibe 12 bis zu dem am Deckelstreifen 25 unterseitig ausgebildeten Zugsteg 28 reicht, aus einer Deckelscheibenebene 49 nach oben verschwenkt.As Fig. 6 shows, as a result of the action of a tensile force Z on the pull tab 27, the predetermined breaking devices 35 and 36 ( FIG. Fig. 3 ) between the free end of the pull tab 27 and the edge skirt 12 destroyed. Subsequently, with the tensile force Z still acting on the pull tab 27, the predetermined breaking devices 53, 54 are destroyed along the cover strip break lines 23, 24, so that a first, radially outer cover strip section 48, which is from the periphery 26 of the cover plate 12 to the underside of the cover strip 25 trained drawbar 28 is sufficient, pivoted from a top plate plane 49 upwards.

Bei Fortsetzung der Öffnungsbewegung 47 wirkt ein Anschlussbereich 50, in dem der Deckelstreifen 25 mit dem Zugsteg 28 verbunden ist, zunächst als Schwenkgelenk, bis der Deckelstreifenabschnitt 48 und der von der Rasteinrichtung 29 zum Deckelstreifen 25 hin verlaufende Zugsteg 28 in etwa in dieselbe Richtung ausgerichtet sind und infolge der auf die Rasteinrichtung 29 wirkenden Zugkraft eine Verformung der Rasteinrichtung 29 radial nach innen und eine Trennung eines zweiten, an seinem Ende jedoch weiterhin mit dem Innenteil der Deckelscheibe 11 verbundenen Deckelstreifenabschnitts 55 aus der Deckelscheibe die Folge ist. Die radiale Verformung der Rasteinrichtung wird durch die parallel zur Deckelscheibe ausgebildete Erstreckung eines an die Rasteinrichtung 29 anschließenden Abschnitts 58 des Zugstegs 28 unterstützt. Zur Verbindung des Abschnitts 58 mit dem Deckelstreifen 25 ist ein quer zur Deckelscheibe 11 verlaufender Abschnitt 59 vorgesehen.Continuing the opening movement 47, a connection region 50, in which the cover strip 25 is connected to the pull web 28, first acts as a swivel joint until the cover strip section 48 and the pull web 28 extending from the latching device 29 towards the cover strip 25 are oriented approximately in the same direction and as a result of acting on the latching device 29 a deformation of the latching device 29 radially inwardly and a separation of a second, but at its end still connected to the inner part of the cover plate 11 lid strip portion 55 from the lid disc is the result. The radial deformation of the latching device is supported by the extension of a section 58 of the pull web 28 that is connected to the latching device 29 parallel to the cover disk. To connect the portion 58 with the lid strip 25 a transverse to the cover plate 11 extending portion 59 is provided.

Darüber hinaus wird die Wirkung der Zugkraft Z zur Erzielung der starken radialen Verformung der Rasteinrichtung 29 dadurch erhöht, dass eine Verformung bzw. Stauchung eines radial inneren Deckelstreifenabschnitt 55 erfolgt, der eine reduzierte Dicke aufweist, sowie durch die Schwächung eines Verformungsquerschnitts des Befestigungsrings 17 infolge der im Befestigungsring 17 im Anschlussbereichs 51 des Zugstegs 28 ausgebildeten Ausnehmung 30.In addition, the effect of the tensile force Z to achieve the strong radial deformation of the latching device 29 is increased by a deformation or compression of a radially inner lid strip portion 55 takes place, which has a reduced thickness, and by the weakening of a deformation cross-section of the mounting ring 17 due to in the attachment ring 17 in the connection region 51 of the pull bar 28 formed recess 30th

Wie Fig. 8 zeigt, erfolgt bei Fortsetzung der Öffnungsbewegung 47 ein vollständiges Lösen der Eingriffsverbindung zwischen der Rasteinrichtung 29 des Befestigungsrings 17 und dem Raststeg 39 des Behälterstopfens 38, so dass die Siegelkappe 10 von dem Behälterverschluss 37 abgenommen werden kann.As Fig. 8 shows, on the continuation of the opening movement 47 is a complete release of the engagement connection between the latching device 29 of the mounting ring 17 and the locking bar 39 of the container stopper 38, so that the sealing cap 10 can be removed from the container closure 37.

In den Fig. 9 bis 12 sind Siegelkappen 60, 61 dargestellt, die bei im Übrigen übereinstimmender Ausgestaltung mit der Siegelkappe 10 eine Rasteinrichtung 62 ( Fig. 9 und 10 ) bzw. eine Rasteinrichtung 63 ( Fig. 11 und 12 ) aufweisen.In the Fig. 9 to 12 Seal caps 60, 61 are shown, which in otherwise coincident configuration with the sealing cap 10, a latching device 62 ( FIGS. FIGS. 9 and 10 ) or a locking device 63 ( FIG. FIGS. 11 and 12 ) .

Die Rasteinrichtung 62 weist angrenzend an den Anschlussbereich 51 des Zugstegs 28 und im Bereich der im Befestigungsring 17 ausgebildeten Ausnehmung 30 eine radial äußere Einkerbung 64 auf. Die Rasteinrichtung 63 weist angrenzend an den Anschlussbereich 51 des Zugstegs 28 und im Bereich der im Befestigungsring 17 ausgebildeten Ausnehmung 30 eine axiale Einkerbung 65 auf.The latching device 62 has a radially outer notch 64 adjacent to the connection region 51 of the pull bar 28 and in the region of the cutout 30 formed in the fastening ring 17. The latching device 63 has an axial notch 65 adjacent to the connection region 51 of the pull bar 28 and in the region of the cutout 30 formed in the fastening ring 17.

Bedingt durch die Einkerbung 64 oder 65 kann es bei der vorstehend unter Bezugnahme auf die Fig. 6 bis 8 erläuterten radialen Verformung der Rasteinrichtung 29 zu einem Aufreißen oder einer Durchtrennung der Rasteinrichtung 29 im Bereich der Einkerbung 64 oder 65 kommen, so dass die zur Lösung des Eingriffs der Rasteinrichtung 29 mit dem Raststeg 39 erforderliche Zugkraft Z reduziert werden kann.Due to the notch 64 or 65, it may in the above with reference to the Fig. 6 to 8 explained radial deformation of the latching device 29 come to a rupture or a severing of the latching device 29 in the region of the notch 64 or 65, so that the time required to solve the engagement of the latching device 29 with the latching web 39 tensile force Z can be reduced.
