Description

Die Erfindung richtet sich auf einen Verschluß für einen flaschenartigen Behälter, insbesondere für Operationsspülwasser oder dergleichen, mit einer angeformten Verschlußkappe, umfassend eine auf ein Gewinde an dem Behälterhals über die Verschlußkappe aufschraubbare Schutzkappe, wobei die Schutzkappe mit einem am Behälter axial festlegbaren Originalitätssicherungsring verbunden ist und wobei die Schutzkappe nach Trennen vom Orignalitätssicherungsring gegen die Verschlußkappe durch weiteres Aufschrauben andrückbar ist und dadurch die Verschlußkappe längs der Sollbruchstelle vom Behälter abgerissen wird.The invention relates to a closure for a bottle-like container, in particular for surgical rinse water or the like, with an integrally formed closure cap, comprising a protective cap which can be screwed onto a thread on the container neck via the closure cap, the protective cap being connected to a tamper-evident securing ring which can be axially fixed to the container, and wherein the protective cap can be pressed against the closure cap by further screwing after separation from the originality securing ring, and the closure cap is thereby torn from the container along the predetermined breaking point.

Ein derartiger Verschluß ist aus der EP-A-50 490 bekannt.Such a closure is known from EP-A-50 490.

Bei solchen flaschenartigen Verpackungen, insbesondere für Operationsspülwasser, muß sichergestellt sein, daß die beim Herstellen der Verpackung und dem gleichzeitigen Befüllen erzielte Sterilität bis zur Verwendung bei der Operation gewährleistet ist, wobei es dann darauf ankommt, daß die hermetisch versiegelte Flasche schnell, mühelos und zuverlässig geöffnet werden kann.In such bottle-like packaging, especially for surgical rinse water, it must be ensured that the sterility achieved in the manufacture of the packaging and the simultaneous filling is guaranteed until use in the operation, in which case it is important that the hermetically sealed bottle is quick, effortless and reliable can be opened.

Diesen Anforderungen werden herkömmliche Verpackungen, wie z.B. die gattungsgemäß als bekannt vorausgesetzte, nicht gerecht.Conventional packaging, such as the generic presupposed as known, not fair.

Bei den bekannten Verpackungen muß z.B. der Originalitätssicherungsring mittels einer Öse an einer Sollbruchstelle aufgetrennt und in Umfangsrichtung abgezogen werden. Eine derartige Aufreiß- und Abziehbewegung ist umständlich und mit einer mit Handschuhen versehenen Hand nur schwer zu bewerkstelligen. Nach dem Entfernen des Originalitätssicherungsringes, der auch Pilferproofring genannt wird, muß die Schutzkappe nach unten gedreht werden, was ebenfalls mit einem erheblichen Kraftaufwand verbunden ist, weil gemäß dem Stand der Technik bei diesem Vorgang eine innere Ringschulter der Schutzkappe zunächst über eine Hinterschneidung an der Verschlußkappe gebracht werden muß, und weil darüber hinaus die aneinander gleitenden Flächen bei diesem Vorgang relativ groß sind. Aufgrund dieses großen Kraftaufwandes bei einer Schutzkappe von verhältnismäßig geringem Außendurchmesser kann es abgesehen von dem Zeitaufwand für den Öffnungsvorgang sogar dazu kommen, daß die sterilen Handschuhe des Operationsassistenzpersonals zerreißen, was naturgemäß mit außerordentlichen Gefahren verbunden ist.In the known packaging, for example, the tamper-evident ring must be separated at a predetermined breaking point by means of an eyelet and pulled off in the circumferential direction. Such a tear-open and pull-off movement is cumbersome and is difficult to accomplish with a gloved hand. After removing the tamper-evident ring, which is also called pilferproof ring, the protective cap must be turned downwards, which is also associated with considerable effort, because according to the prior art, an inner ring shoulder of the protective cap initially has an undercut on the closure cap during this process must be brought, and because the sliding surfaces are relatively large in this process. Because of this great effort with a protective cap of relatively small outer diameter, it can even happen that the sterile gloves of the Operations assistants tear apart what is naturally associated with extraordinary dangers.

Um den Originalitätssicherungsring gegen ein axiales Abziehen zu sichern, ist es bekannt, diesen mit Vorsprüngen und den Behälterhals mit korrespondierenden Hinterschneidungen zu versehen. Bei einem in Umfangsrichtung abziehbaren Originalitätssicherungsring mit einer radialen Sollbruchstelle müssen diese Vorsprünge relativ groß sein, um einen sicheren Sitz zu gewährleisten, was wiederum die Handhabung beim Öffnen erschwert. Bei anderen bekannten Lösungen ist der Originalitätssicherungsring mit einem unterhalb desselben am Behälterhals liegenden Haltering verbunden, welcher mit dem Behälter selbst durch Ultraschallschweißen oder Kleben verbunden ist. Allerdings wird hierdurch nicht die zu fordernde hohe Dichtigkeit in allen Fällen gewährleistet.In order to secure the tamper-evident ring against axial pulling off, it is known to provide it with projections and the container neck with corresponding undercuts. In the case of a tamper-evident securing ring which can be peeled off in the circumferential direction and has a radial predetermined breaking point, these projections must be relatively large in order to ensure a secure fit, which in turn makes handling when opening difficult. In other known solutions, the tamper-evident ring is connected to a retaining ring located below it on the container neck, which is connected to the container itself by ultrasonic welding or gluing. However, this does not guarantee the high level of tightness required in all cases.

Der Erfindung liegt die Aufgabe zugrunde, einen Verschluß der eingangs genannten Art so auszugestalten, daß bis zur Verwendung bei einer Operation ein absolut dichter Verschluß gewährleistet ist, daß der Verschluß sich im Bedarfsfall aber schnell und mühelos öffnen läßt, wobei sowohl das Aufschrauben der Schutzkappe zum Abreißen der Verschlußkappe als auch das anschließende Abschrauben der Schutzkappe leichtgängig und problemlos möglich sein soll, und wobei letztlich auch ein völlig dichtes und steriles Aufschrauben der Schutzkappe dann möglich sein soll, wenn die Verschlußkappe bereits abgerissen ist.The invention has for its object to design a closure of the type mentioned in such a way that an absolutely tight closure is guaranteed until use in an operation, but that the closure can be opened quickly and effortlessly if necessary, both unscrewing the protective cap for Tearing off the cap and the subsequent unscrewing of the protective cap should be smooth and easy, and ultimately a completely tight and sterile screwing on of the protective cap should be possible when the cap has already been torn off.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß der Innendurchmesser des durch korrespondierende Vorsprünge und Hinterschneidungen am Behälter festlegbaren Originalitätssicherungsringes an seiner Oberkante größer als der Außendurchmesser der Schutzkappe an ihrer Unterseite ist, wobei zwischen Originalitätssicherungsring und Schutzkappe abreißbare Verbindungsstege angeordnet sind, und daß unterhalb der Unterkante der Schutzkappe eine Ringschulter am Behälter mit einer konischen Auflaufdichtfläche für den Unterrand der Schutzkappe angeordnet ist.This object is achieved in that the inner diameter of the tamper-evident ring, which can be fixed by corresponding projections and undercuts on the container, is larger on its upper edge than the outer diameter of the protective cap on its underside, wherein connecting webs which can be torn off are arranged between the tamper-evident ring and the protective cap, and that below the lower edge of the Protective cap an annular shoulder is arranged on the container with a conical sealing surface for the lower edge of the protective cap.

Durch die vorgesehene, von Arzneimittelflaschen an sich bekannte Verbindung zwischen Originalitätssicherungsring und Schutzkappe ist es möglich, den Originalitätssicherungsring durch einfaches weiteres Aufschrauben der Schutzkappe in den axial nach unten festgelegten Originalitätssicherungsring hinein zu lösen. Demnach braucht für die Trennung von Schutzkappe und Originalitätssicherungsring nicht eine gesonderte Bewegung vorgenommen zu werden, insbesondere entfällt das mühsame radiale Aufbrechen und Abziehen in Umfangsrichtung. Die Schraubbewegung nach unten muß zum Abreißen der Verschlußkappe ohnehin vorgenommen werden, so daß die Verwendung eines derartigen Originalitätssicherungsringes im vorliegenden Fall besonders günstig ist. Die Schutzkappe bildet gleichzeitig einen sicheren Schutz bei der Lagerung und beim Transport.The proposed connection, known per se from pharmaceutical bottles, between tamper-evident ring and protective cap makes it possible to loosen the tamper-evident ring by simply screwing on the protective cap further into the tamper-evident ring fixed axially downward. Accordingly, a separate movement does not need to be carried out for the separation of the protective cap and tamper-evident ring, in particular the tedious radial opening and peeling in the circumferential direction is eliminated. The downward screwing movement must be carried out anyway to tear off the closure cap, so that the use of such a tamper-evident ring is particularly favorable in the present case. The protective cap also provides secure protection during storage and transportation.

Die Ausbildung der Stege kann bereits beim Spritzen erfolgen, so daß der gesamte Verschluß umfassend die Schutzkappe und den Originalitätssicherungsring in einem Spritzvorgang hergestellt werden kann. Alternativ ist es auch möglich, durch Einbringung einer umlaufenden Perforierung nach dem Spritzen des Verschlusses stegartige Verbindungen auszubilden.The webs can already be formed during spraying, so that the entire closure includes the protective cap and the tamper-evident ring a spraying process can be produced. Alternatively, it is also possible to form web-like connections by introducing a circumferential perforation after the closure has been sprayed.

Durch die konische Auflaufschulter am Flaschenhals wird durch die fortgesetzte Aufschraubbewegung eine absolut dichte Verbindung zwischen der Schutzkappe und dieser Auflaufschulter erreicht, so daß der Behälter vor der Operation bereits in diese Position gebracht werden kann, um das Öffnen noch weiter zu beschleunigen und zu erleichtern oder aber mittels einer Injektionsspritze vor der Operation Zusätze in den Behälter injiziert werden können, wobei auch danach noch eine hermetische und sterile Abdichtung durch die aufgesetzte Schutzkappe erzielbar ist.Due to the conical casserole shoulder on the bottle neck, an absolutely tight connection between the protective cap and this casserole shoulder is achieved by the continued screwing-on movement, so that the container can be brought into this position before the operation in order to accelerate and facilitate opening even more, or else additives can be injected into the container before the operation by means of an injection syringe, whereby a hermetic and sterile seal can also be achieved afterwards by the attached protective cap.

In weiterer Ausgestaltung der Erfindung ist vorgesehen, daß die Innenseite der Unterkante der Schutzkappe einen konischen Anlageabschnitt aufweist. Dieser Anlageabschnitt ist korrespondierend zur Auflaufschulter ausgebildet, so daß zwei aneinanderliegende Dichtflächen geschaffen werden.In a further embodiment of the invention it is provided that the inside of the lower edge of the protective cap has a conical contact section. This contact section is designed to correspond to the overrun shoulder, so that two adjacent sealing surfaces are created.

Günstigerweise kann auf die Auflaufschulter ein dünner, elastischer Dichtring aufgesetzt werden. Dieser Dichtring muß so gewählt werden, daß er formtechnisch bedingte Nahtvorsprünge an der Behälteraußenwand auszugleichen vermag.A thin, elastic sealing ring can advantageously be placed on the casserole shoulder. This sealing ring must be selected in such a way that it is able to compensate for seam projections on the outer wall of the container due to the shape of the technology.

Vorteilhafterweise ist wenigstens der vertikale Abschnitt der Schutzkappe doppelwandig ausgebildet, wobei an der Innenseite der inneren Wand das Schraubgewinde und an der Innenseite der äußeren Wand der konische Anlageabschnitt ausgebildet ist. Durch diese Doppelwandigkeit wird zum einen der Außendurchmesser der Schutzkappe trotz Verwendung eines Normgewindes vergrößert, so daß die Schutzkappe erheblich leichter zu handhaben ist, andererseits wird die Elastizität der Außenwand erhöht, so daß zuverlässige, definierte Anlage der Anlageschulter am Unterrand der Schutzkappe an der Auflaufschulter am Behälterhals gewährleistet ist.Advantageously, at least the vertical section of the protective cap is double-walled, wherein the screw thread is formed on the inside of the inner wall and the conical contact section is formed on the inside of the outer wall. Due to this double wall, the outer diameter of the protective cap is increased despite the use of a standard thread, so that the protective cap is considerably easier to handle, on the other hand the elasticity of the outer wall is increased, so that reliable, defined contact of the contact shoulder on the lower edge of the protective cap on the overrun shoulder on Container neck is guaranteed.

Mit Vorteil ist vorgesehen, daß im ungeöffneten Zustand ein innenliegender, ringförmiger Vorsprung der Schutzkappe in eine Hinterschneidung am Behälterhals unterhalb der Verschlußkappe eingreift. Hierdurch wird erreicht, daß ein entsprechender Eingriff beim Öffnen des Behälters im Bedarfsfall nicht erst durch die Bedienungsperson hergestellt werden muß, so daß hierdurch das Aufschrauben der Schutzkappe weiter erleichtert wird. Beim Abschrauben der Schutzkappe wird die Verschlußkappe in an sich bekannter Weise durch den in die Hinterschneidung eingreifenden Vorsprung mitgenommen.It is advantageously provided that, in the unopened state, an inner, annular projection of the protective cap engages in an undercut on the container neck below the closure cap. This ensures that a corresponding intervention when opening the container does not have to be made by the operator if necessary, so that the screwing on of the protective cap is further facilitated. When the protective cap is unscrewed, the cap is carried along in a manner known per se by the projection engaging in the undercut.

An der Außenseite der Verschlußkappe können Greiflamellen angeordnet sein, um die aufgrund des vergrößerten Durchmessers ohnehin verbesserte Handhabbarkeit der Verschlußkappe noch weiter zu verbessern.Gripping lamellae can be arranged on the outside of the closure cap in order to further improve the manageability of the closure cap, which is improved anyway due to the enlarged diameter.

Um eine möglichst geringe, definierte Reibung zwischen der Schutzkappe und der Verschlußkappe beim Nachuntenschrauben der Schutzkappe zu erzielen, kann vorgesehen sein, daß an der Innenseite des Deckelbereichs der Schutzkappe eine nach innen gerichtete Ausbauchung angeordnet ist. Diese weist vorzugsweise eine etwa kugelkalottenförmige Konfiguration auf. Beim Nachuntenschrauben der Schutzkappe kommt der Pol der Kalotte auf der ebenen Oberseite der Verschlußkappe zu liegen, so daß bei der Drehbewegung eine sehr geringe Reibung auftritt und gleichwohl die Verschlußkappe definiert und sicher nach unten gedrückt wird.To minimize the defined friction between the protective cap and the closure cap when screwing down To achieve the protective cap, it can be provided that an inward bulge is arranged on the inside of the lid area of the protective cap. This preferably has an approximately spherical cap-shaped configuration. When the protective cap is screwed down, the pole of the calotte comes to rest on the flat upper side of the cap, so that very little friction occurs during the rotary movement and the cap is nevertheless defined and pressed down securely.

Alternativ hierzu ist es auch möglich, daß an der Innenseite des Deckelbereiches der Schutzkappe wenigstens ein nach unten gerichteter, in Umfangsrichtung kontinuierlich die Höhe verändernder Rippenvorsprung angeordnet ist. Vorzugsweise sind zwei sich je über einen Winkelbereich von 180° erstreckende, derartige Vorsprünge vorgesehen. Hierdurch wird erreicht, daß beim Aufschrauben auf die Verschlußkappe ein punktueller, asymmetrischer Andruck ausgeübt wird, so daß diese mit fortschreitender Drehbewegung mit geringstem Kraftaufwand abgeschert wird.As an alternative to this, it is also possible for at least one downwardly directed rib projection which continuously changes in height in the circumferential direction to be arranged on the inside of the cover region of the protective cap. Preferably, two such projections each extending over an angular range of 180 ° are provided. This ensures that when the screw cap is screwed on, a selective, asymmetrical pressure is exerted, so that it is sheared off with the least amount of force as the rotary movement progresses.

Das Gewinde am Behälterhals ist günstigerweise ein Trapez-Normgewinde. Ein solches Normgewinde, welches z.B. eine Steigung von 3 mm pro Windung haben kann, ist herstellungstechnisch problemlos und stellt eine zuverlässige Kraftübertragung sowohl beim Aufschrauben als auch beim Abschrauben sicher.The thread on the neck of the container is conveniently a standard trapezoidal thread. Such a standard thread, which can have, for example, a pitch of 3 mm per turn, is problem-free in terms of production technology and ensures reliable power transmission both when screwing on and when unscrewing.

Fig. 3
on the left a section and on the right a side view of a protective cap according to the invention, which is placed on a container according to FIG. 1.

Ein in Fig. 1 dargestellter Behälter umfaßt einen flaschenartigen Grundkörper 1, an dessen Oberseite ein Ringbund 2 im Anschluß an einen konischen Übergangsabschnitt 2′ ausgebildet ist. An den Ringbund 2 schließt sich nach oben ein Ringbereich 3 verminderten Querschnitts mit einer Mehrzahl von Hinterschneidungen 4 an, welche sich jeweils über einen begrenzten Umfangswinkelbereich erstrecken.A container shown in Fig. 1 comprises a bottle-like base body 1, on the top of which an annular collar 2 is formed following a conical transition section 2 '. At the top of the ring collar 2 is a ring region 3 of reduced cross-section with a plurality of undercuts 4, each of which extends over a limited circumferential angle region.

Wiederum oberhalb des Bereiches 3 ist eine Auflaufschulter 5 ausgebildet, welche eine sich nach oben zu verjüngende, konische Auflauffläche 6 aufweist.Again, above the area 3, a ramp shoulder 5 is formed, which has a conical ramp surface 6 to be tapered upwards.

Hieran anschließend befindet sich ein Gewindeabschnitt 7 wiederum verminderten Durchmessers mit einem NormTrapezgewinde 8.This is followed by a threaded section 7, again of reduced diameter, with a standard trapezoidal thread 8.

Zwischen einem sich an den Gewindeabschnitt 7 anschließenden Zylinderabschnitt 9 nochmals verminderten Durchmessers und der Verschlußkappe 10 ist eine Sollbruchstelle 11 ausgebildet, welche insbesondere in Fig. 2 gut zu erkennen ist und einen nach innen gerichteten Abschnitt 12 der Verschlußkappe umfaßt, welcher über eine sehr dünne Wandung 13 mit dem Zylinderabschnitt 9 verbunden ist. Die Verschlußkappe 10 ist an ihrer Oberseite durch eine etwa ebene Fläche 14 abgeschlossen.A predetermined breaking point 11 is formed between a cylinder section 9, which is again of reduced diameter, adjoining the threaded section 7, and the closure cap 10, which can be seen particularly well in FIG. 2 and comprises an inwardly directed section 12 of the closure cap, which has a very thin wall 13 is connected to the cylinder section 9. The closure cap 10 is closed at its top by an approximately flat surface 14.

Die in Fig. 3 dargestellte Schutzkappe 15 ist im Ausführungsbeispiel mit einem Originalitätssicherungsring 16 einstückig gespritzt. Der Außendurchmesser D1 der Schutzkappe 15 an deren Unterkante 17 ist kleiner als der Innendurchmesser D2 des Originalitätssicherungsrings 16 an dessen Oberkante 18. Die Schutzkappe 15 ist in diesem Bereich mit dem Originalitätssicherungsring 16 über eine Mehrzahl von Verbindungsstegen 19 verbunden.The protective cap 15 shown in FIG. 3 is injection-molded in one piece in the exemplary embodiment with a tamper-evident ring 16. The outer diameter D1 of the protective cap 15 on its lower edge 17 is smaller than the inner diameter D2 of the tamper-evident ring 16 on its upper edge 18. The protective cap 15 is connected in this area to the tamper-evident ring 16 via a plurality of connecting webs 19.

Der Originalitätssicherungsring 16 weist im Bereich seiner Unterkante 20 eine Mehrzahl von Vorsprüngen 21 auf, welche korrespondierend zu den Hinterschneidungen 4 an der Oberseite des Behälters ausgebildet sind und in diese so eingerastet werden können, daß der Originalitätssicherungsring 16 in axialer Richtung festgelegt ist.The tamper-evident ring 16 has in the region of its lower edge 20 a plurality of projections 21 which are designed to correspond to the undercuts 4 on the top of the container and can be snapped into the latter in such a way that the tamper-evident ring 16 is fixed in the axial direction.

Der vertikal verlaufende Wandabschnitt 22 der Schutzkappe 15 ist doppelwandig ausgebildet, wobei an der Innenseite 23 der Innenwand 24 ein Gewinde 25 korrespondierend zu dem Gewinde 8 ausgebildet ist.The vertically extending wall section 22 of the protective cap 15 is double-walled, a thread 25 corresponding to the thread 8 being formed on the inside 23 of the inner wall 24.

Die innenliegende Wand 24 ist mit der außenliegenden Wand 26 über einen sich radial erstreckenden Schulterabschnitt 27 verbunden. An der Unterkante 17 der Schutzkappe 15 ist an der Innenseite der äußeren Wand 26 ein Anlageabschnitt 28 ausgebildet.The inner wall 24 is connected to the outer wall 26 via a radially extending shoulder section 27. A contact section 28 is formed on the lower edge 17 of the protective cap 15 on the inside of the outer wall 26.

An der Oberseite 29 der Schutzkappe 15 ist eine sich nach innen erstreckende Ausbauchung 30 vorgesehen.On the top 29 of the protective cap 15, an inwardly extending bulge 30 is provided.

An einem zylinderförmigen Abschnitt 31 verminderten Durchmessers oberhalb des radialen Schulterabschnitts 27 ist im Bereich von dessen innerer Unterkante 32 ein ringförmiger Vorsprung 33 ausgebildet.An annular projection 33 is formed on a cylindrical section 31 of reduced diameter above the radial shoulder section 27 in the region of its inner lower edge 32.

Wenn die Schutzkappe 15 im Auslieferzustand der Verpackung aufgesetzt ist, liegt der ringförmige Vorsprung 33 im Bereich des Zylinderabschnitts 9 im Halsbereich des Behälters und hintergreift den Abschnitt 12 der Verschlußkappe 10. In diesem Zustand ist der Originalitätssicherungsring durch die in die Hinterschneidungen 4 am Behälterhals eingreifenden Vorsprünge 21 axial festgelegt.When the protective cap 15 is put on in the delivery state of the packaging, the annular projection 33 lies in the region of the cylinder section 9 in the neck region of the container and engages behind the section 12 of the closure cap 10. In this state the tamper-evident ring is due to the projections engaging in the undercuts 4 on the container neck 21 axially fixed.

Zum Öffnen der Verschlußkappe 10 wird die Schutzkappe 15 nach unten geschraubt, was aufgrund des relativ großen Außendurchmessers der Schutzkappe 15 einerseits und der dort zusätzlich noch angebrachten Grifflamellen 34 leicht möglich ist. Die Ausbauchung 30 der Schutzkappe 15 gelangt zur Anlage an dem flachen oberen Ende 14 der Verschlußkappe 10 und drückt diese nach unten, so daß die Verschlußkappe 10 an der Sollbruchstelle 11 von dem Grundkörper 1 des Behälters getrennt wird. Dabei ist der Reibungswiderstand beim Drehen aufgrund der punktförmigen Anlage des Pols 35 der Ausbauchung 30 an der ebenen Fläche 14 der Verschlußkappe 10 sehr gering, so daß diese Drehbewegung mühelos bewerkstelligt werden kann.To open the closure cap 10, the protective cap 15 is screwed downwards, which is due to the relatively large outer diameter of the protective cap 15 on the one hand and the handle lamellae additionally attached there 34 is easily possible. The bulge 30 of the protective cap 15 comes into contact with the flat upper end 14 of the closure cap 10 and presses it downward, so that the closure cap 10 is separated from the base body 1 of the container at the predetermined breaking point 11. The frictional resistance when rotating is very low due to the point-like contact of the pole 35 of the bulge 30 on the flat surface 14 of the closure cap 10, so that this rotary movement can be accomplished effortlessly.

Gleichzeitig werden durch diese Drehbewegung die Stege 19 zwischen dem Originalitätssicherungsring 16 und der Schutzkappe 15 abgerissen, so daß die Schutzkappe 15 in den Originalitätssicherungsring 16 hineingeschraubt werden kann. Es bedarf also keiner gesonderten Manipulation des Originalitätssicherungsringes 16, um diesen zu lösen.At the same time, the webs 19 between the tamper-evident ring 16 and the protective cap 15 are torn off by this rotary movement, so that the protective cap 15 can be screwed into the tamper-evident ring 16. No special manipulation of the tamper-evident ring 16 is therefore required in order to release it.

Bei der Aufschraubbewegung gelangt der Anlagebereich 28 mit seiner konisch verlaufenden Fläche zur Anlage an der Auflaufschulter 6 im Halsbereich des Behälters, wobei eine dichte Verbindung hergestellt wird, so daß in diesem Zustand der Behälter trotz abgerissener Verschlußkappe 15 nach wie vor hermetisch dicht und steril ist. Die Dichtheit der Verbindung kann durch das Aufbringen eines dünnen, elastischen Dichtrings 36 noch erhöht werden.During the screwing-on movement, the conical surface 28 comes to rest against the casserole shoulder 6 in the neck region of the container, a tight connection being made so that in this state the container is still hermetically sealed and sterile in spite of the cap 15 being torn off. The tightness of the connection can be increased by applying a thin, elastic sealing ring 36.

Unmittelbar anschließend oder zu einem beliebigen späteren Zeitpunkt kann nun die Schutzkappe nach oben abgeschraubt werden, wobei auch in dieser Bewegungsrichtung aufgrund des verwendeten Trapezgewindes 8 eine sichere Kraftübertragung erzielt wird. Hierbei wird die Verschlußkappe 10, welche bereits abgetrennt ist, durch den umlaufenden Vorsprung 33, welcher an dem Abschnitt 12 der Verschlußkappe 10 angreift, mit nach oben weggezogen.Immediately afterwards or at any later point in time, the protective cap can now be unscrewed, also in this direction of movement due to the trapezoidal thread 8 used a secure power transmission is achieved. Here, the closure cap 10, which has already been separated, is pulled upwards by the circumferential projection 33, which engages the section 12 of the closure cap 10.

Alternativ zu der Ausbauchung 30 kann vorgesehen sein, daß an der Innenseite der Schutzkappe 15 ein umlaufender Stegvorsprung 37 mit einer sich progressiv ändernden Höhe angeordnet ist. Dieser Stegvorsprung 37 greift an einer in Fig. 1 gestrichelt eingezeichneten Schulter 38 der Verschlußkappe 10 punktförmig asymmetrisch an, so daß die Verschlußkappe 10 zunächst einseitig und dann mit fortgesetzter Drehbewegung umlaufend abgeschert wird, wodurch ebenfalls ein besonders müheloses Abtrennen der Verschlußkappe 10 gewährleistet ist.As an alternative to the bulge 30, it can be provided that a circumferential web projection 37 with a progressively changing height is arranged on the inside of the protective cap 15. This web projection 37 engages a shoulder 38 of the closure cap 10 shown in broken lines in FIG.

Im Bereich der Stege 19 sind an dem Originalitätssicherungsring 16 eine nach innen vorspringende Dichtlippe 41 und an der Schutzkappe 15 an der Außenseite von deren Unterrand eine Dichtlippe 40 vorgesehen. Beim maschinellen Aufsetzen der Schutzkappe 15 wird diese gegen den Originalitätssicherungsring 16 angedrückt, so daß zwischen den Dichtlippen 40,41 eine dichte Verbindung hergestellt wird und nach dem Aufsetzen der Schutzkappe 15 dort kein Schmutz mehr eindringen kann. Etwa in der Mitte der Innenwand des Originalitätssicherungsrings 16 ist eine weitere Dichtlippe 42 vorgesehen, welche gegen den korrespondierenden Abschnitt des Flaschenhalses anliegt und eine zusätzliche Abdichtung gewährleistet.In the area of the webs 19, an inwardly projecting sealing lip 41 is provided on the tamper-evident ring 16 and a sealing lip 40 is provided on the protective cap 15 on the outside of its lower edge. When the protective cap 15 is put on mechanically, it is pressed against the tamper-evident locking ring 16, so that a tight connection is established between the sealing lips 40, 41 and after the protective cap 15 has been put on, no more dirt can penetrate there. Approximately in the middle of the inner wall of the tamper-evident ring 16, a further sealing lip 42 is provided, which against the corresponding Section of the bottle neck rests and ensures an additional seal.

An der Verschlußkappe ist ein etwa horizontal verlaufender Schulterabschnitt 43 vorgesehen, welcher das Aufsetzen und das Zusammenwirken mit der Schutzkappe 15 ermöglicht.An approximately horizontally extending shoulder section 43 is provided on the closure cap, which enables the attachment and interaction with the protective cap 15.

Auf der Außenseite des Originalitätssicherungsringes 16 einerseits und des Wandabschnittes 22 der Schutzkappe 15 andererseits sind achsparallel verlaufende verstärkt ausgebildete Rippen 44 bzw. 45 ausgebildet. Diese dienen dazu, beim maschinellen Verschließen der Flasche mittels eines Verschließkopfes eine gleichmäßige Mitnahme des Originalitätssicherungsringes 16 mit der Schutzkappe 15 sicherzustellen. Hiermit sollen die fein ausgebildeten Verbindungsstege 19 vor einem Abreißen gesichert werden. Wenn die Rippen 44,45, und zwar insbesondere die Rippen 44, nicht vorgesehen sein können, dann ist es von Vorteil, wenn die Verbindungsstege 19 zusätzlich unterstützt werden, wie dies im einzelnen in der DE-PS 27 04 461 dargestellt, beschrieben und geschützt ist.On the outside of the tamper-evident ring 16 on the one hand and the wall section 22 of the protective cap 15 on the other hand, axially parallel reinforced ribs 44 and 45 are formed. These serve to ensure even entrainment of the tamper-evident ring 16 with the protective cap 15 when the bottle is closed mechanically by means of a closing head. This is intended to secure the finely formed connecting webs 19 from tearing off. If the ribs 44, 45, in particular the ribs 44, cannot be provided, then it is advantageous if the connecting webs 19 are additionally supported, as is described, described and protected in detail in DE-PS 27 04 461 is.
