Abstract

The container (10) has an adapter sleeve fitting over its top end, which accommodates a cylindrical screw cap (11) with a flat closed end. The cap has an outer housing (14), an intermediate housing (15) and an inner housing (25) which engages with the nozzle (26) for application of the glue. A cylindrical portion (43) presses down on a flange (40) on the nozzle, and a sealing pin (51) penetrates the tip of the nozzle cone to prevent escape of glue when the cap is in place. The intermediate housing incorporates a curved portion (18) which acts as a spring.

Description

Die Erfindung betrifft einen Behälter gemäß dem Oberbegriff des Anspruches 1.The invention relates to a container according to the preamble of claim 1.

Bei einem derartigen Behälter schützt die die Behälteröffnung verschließende Membran den Behälterinhalt bis zum ersten Abgabevorgang zuverlässig vor einem unbeabsichtigten Austritt aus dem Behälter. Vor der ersten Abgabe des Behälterinhalts muss die Membran durchstoßen werden. Zu diesem Zweck ist beispielsweise ein Behälter der eingangs genannten Art bekannt, in dessen Schraubdeckel ein Dorn integriert ist, mit dessen Hilfe, nachdem die Kanüle vom Behälter abgeschraubt ist, die Membran durchstoßen wird, woraufhin die Kanüle bestimmungsgemäß auf den Behälter geschraubt und diese Kanüle nach dem Abgabevorgang des im Behälter enthaltenen fließfähigen Mediums durch den Schraubdeckel wieder verschlossen wird. Diese Ausbildung des herkömmlichen Behälters erfordert einen relativ komplizierten manuellen Eingriff durch einen Nutzer, bis schließlich zum ersten Mal aus dem Behälter fließfähiges Medium abgebbar ist. Beim manuellen Durchstechen der Membran ist nicht auszuschließen, dass der Behälterinhalt austritt, was z. B. im Fall von Sekundenkleber sehr unangenehm sein kann.In such a container protects the container opening occluding membrane the container contents until the first dispensing process reliable against unintentional leakage from the container. Before the first delivery of the contents of the container the membrane must be punctured. For this purpose, for example a container of the type mentioned, in the screw cap a mandrel is integrated, with its Help after the cannula is unscrewed from the container, the Membrane is pierced, whereupon the cannula as intended screwed onto the container and this cannula after the dispensing process the flowable medium contained in the container is closed again by the screw cap. This training the conventional container requires a relative complicated manual intervention by a user until finally, for the first time from the container flowable medium is deliverable. When manually piercing the membrane it can not be ruled out that the container contents will leak, what for. B. be very uncomfortable in the case of superglue can.

Die DE 198 45 686 A1 zeigt und beschreibt bereits einen Behälter der im Oberbegriff des neuen Anspruches 1 bezeichneten Art. Dabei umfasst die aus mehreren einzelnen Komponenten zusammengesetzte Schraubdeckelanordnung ein Schraubdeckelteil, welches in einem Ausgangszustand direkt mit der Kanüle drehgekoppelt ist, wobei sich die letztere jedoch gegenüber dem Schraubdeckelteil axial verschieben kann. Die Kanüle ist über erste Stellgewindemittel in einem ringförmigen Teil verdrehbar und auf diese Weise axial verstellbar angeordnet, und das Schraubdeckelteil ist über zu den ersten Stellgewindemitteln gegenläufige Stellgewindemittel ebenfalls relativ zu dem ringförmigen Teil verdrehbar und axial verstellbar. Das ringförmige Teil wird auf den Behälterhals aufgeschraubt. Bei einer Verdrehung des Schraubdeckelteils im Öffnungssinne wird die Kanüle in die Behälteröffnung hineinbewegt; das Schraubdeckelteil dreht sich in einer ersten Ausgestaltung zunächst in einem steigungslosen Stellgewindeabschnitt (Segment 20) und wird anschließend vom ringförmigen Teil abgeschraubt, oder es wird in einer anderen Ausgestaltung gleichzeitig infolge einer unterschiedlichen Steigung der Stellgewindemittel mit geringerer Axialgeschwindigkeit von dem ringförmigen Teil abgeschraubt. Die Kanüle wird nach Erreichen ihrer Betriebsstellung im ringförmigen Teil verrastet.DE 198 45 686 A1 already shows and describes a container designated in the preamble of the new claim 1 Art.

The cannula is over first adjusting thread in an annular part rotatable and arranged axially adjustable in this way, and that Screw cap part is over to the first adjusting screws Opposing adjusting thread also relative to the annular part rotatable and axially adjustable. The annular Part is screwed onto the container neck. At a Twisting of the screw cap part in the opening direction is the cannula is moved into the container opening; the screw cap part rotates in a first embodiment initially in a stepless adjusting threaded section (segment 20) and then unscrewed from the annular part, or it will result in another embodiment simultaneously a different pitch of the adjusting thread at a lower axial velocity from the annular part unscrewed. The cannula will after reaching its operating position latched in the annular part.

Ein Nachteil der bekannten Lösung wird darin gesehen, dass nach dem ersten Öffnen des Behälters das einen Teil der Stellgewindemittel zum axialen Verstellen der Kanüle bildende ringförmige Teil am Behälter verbleibt. Dadurch ist einerseits der obere Behälterbereich verhältnismäßig voluminös, was beim Klebemittelauftrag insbesondere an schwer zugänglichen Stellen nachteilig sein kann. Andererseits besteht auch die Gefahr, dass nach dem ersten Gebrauch das Schraubdeckelteil mit dem ringförmigen Teil und/oder der Kanüle verklebt, so dass beim erneuten Abschrauben des Schraubdeckelteils das ringförmige Teil mit der Kanüle mitgenommen, d. h. die gesamte Schraubdeckelanordnung abgeschraubt wird. Dieser Effekt wird noch dadurch begünstigt, dass die Kanüle im ringförmigen Teil und nicht - wie gemäß einer Ausgestaltung der vorliegenden Erfindung - am Behälter arretiert wird. A disadvantage of the known solution is seen in that after the first opening of the container that is part of the Stellgewindemittel for axial displacement of the cannula forming annular part remains on the container. This is on the one hand the upper tank area relatively bulky, which is particularly difficult to access when applying glue Digits may be disadvantageous. On the other hand, too the danger that after the first use the screw cap part glued to the annular part and / or the cannula, so that when you unscrew the screw cap part the annular part taken with the cannula, d. H. the whole Screwed lid assembly is unscrewed. This effect is still favored by the fact that the cannula in the annular Part and not - as in one embodiment of the present Invention - is locked to the container.

Aufgabe der Erfindung ist es, einen Behälter der im Oberbegriff des Anspruches 1 genannten Art zu schaffen, bei welchem einerseits nach dem ersten Öffnen die Kanüle dauerhaft ihre Stellung in der Behälteröffnung einnimmt.The object of the invention is to provide a container in the preamble of the claim 1 mentioned type, in which on the one hand, after the first opening, the cannula permanently assumes its position in the container opening.

Diese Aufgabe ist erfindungsgemäß durch die im Anspruch 1 aufgeführten Merkmale gelöst.This object is achieved by the in the claim 1 listed features solved.

Gemäß der erfindungsgemäßen Konstruktion wird die Kanüle nicht direkt durch den verdrehbaren ersten Schraubdeckelteil axial einwärts verstellt, sondern durch ein bei Verdrehung des ersten Schraubdeckelteils axial einwärts bewegtes, stets im Schraubdeckelteil verbleibendes Kanülenverschiebeteil 25 in der Einwärtsrichtung mitgenommen. Beim Öffnen des Behälters werden der erste Schraubdeckelteil, das Kanülenverschiebeteil und der zweite Schraubdeckelteil zu einer integrierten Einheit miteinander verbunden und gemeinsam vom Behälterhals abgeschraubt, und es verbleibt nur die Kanüle am Behälter. Auch ein Verkleben der Schraubdeckelanordnung etwa mit der Kanüle oder mit dem Behälterhals kann nie dazu führen, dass beim Abschrauben der Schraubdeckelanordnung die Kanüle mit abgeschraubt wird, da sie unverdrehbar in der Behälteröffnung sitzt. Das wird noch dadurch unterstützt, dass die Kanüle gemäß einer Ausgestaltung der Erfindung am Behälter verrastet wird. According to the construction according to the invention, the cannula becomes not directly through the rotatable first screw cap part axially inwardly adjusted, but by a twisting the first screw cap axially inwardly moved, always in the screw cap part remaining Kanülenverschiebeteil 25th taken in the inward direction. When opening the container become the first screw cap part, the cannula shifting part and the second screw cap part to an integrated Unit connected together and together from the container neck unscrewed, leaving only the cannula on the container. Also, a bonding of the screw cap assembly approximately with the Cannula or with the container neck can never cause when unscrewing the screw cap assembly with the cannula is unscrewed as it is non-rotatable in the container opening sitting. This is further supported by the cannula according to an embodiment of the invention locked on the container becomes.

Eine Fixierung der sich in Endstellung befindlichen Kanüle am Behälter erfolgt bevorzugt durch ein Rastmittel zum Haltern der Kanüle in dieser Stellung. Dieses Rastmittel kann beispielsweise eine Ringwulst im Bereich des unteren Endes der Kanüle sein, welche die Behälteröffnung hintergreift, sobald die Kanüle sich in ihrer Endstellung befindet, in der sie die Membran durchstoßen hat.A fixation of the cannula located in the end position takes place on the container preferably by a latching means for holding the cannula in this position. This locking means may for example a Be annular bead in the region of the lower end of the cannula, which engages behind the container opening as soon as the cannula is in its final position, in which they are the membrane has pierced.

Der erfindungsgemäße Stelltrieb für die Kanüle kann grundsätzlich in unterschiedlicher Weise realisiert werden. Gemäß einer bevorzugten Ausführungsform ist der integrierte Stelltrieb in Art eines Kulissenantriebs gebildet, der die Öffnungsdrehbewegung für den Schraubdeckel in eine axiale Betätigungsbewegung für die Kanüle umsetzt, so dass diese entgegen der axialen Aufwärtsbewegung des Schraubdeckels abwärts zur Membran bewegt wird, diese durchstößt und in ihrer Endstellung in der Behälteröffnung axial festgesetzt wird.The actuating drive according to the invention for the cannula can basically be realized in different ways. According to a preferred embodiment is the integrated actuator formed in the manner of a link drive, the opening rotational movement for the screw cap in an axial actuating movement for the cannula, so that this counter the axial upward movement of the screw down is moved to the membrane, this pierces and in its final position is fixed axially in the container opening.

Eine besonders bevorzugte Ausführungsform des Stelltriebs des erfindungsgemäßen Behälters sieht vor, dass die Kanüle in dem z.B. durch einen auf den Behälter aufgesetzten Kanülenhalter gebildeten Behälterhals im Kanülenhalter drehfest gelagert ist, und dass der Stelltrieb eine Mehrzahl koaxial angeordneter Teile umfasst. Diese Teile umfassen einen zweiten Schraubdeckelteil, der mit seinem Gewinde im Eingriff mit einem behälterfesten Gewinde steht, einen ersten Schraubdeckelteil, der mit dem zweiten Schraubdeckelteil drehbar und axial feststehend verbunden ist, und ein die Kanüle axial in Richtung auf die Membran beaufschlagendes Kanülenverschiebeteil, das sich im Gewindeeingriff mit dem ersten Schraubdeckelteil befindet und zum axialen Verschieben der Kanüle durch Umsetzen der Drehbewegung des zweiten Schraubdeckelteils in eine Hubbewegung relativ zu diesem drehfest angeordnet ist. Die Gewindeverbindung zwischen dem ersten Schraubdeckelteil und dem Kanülenverschiebeteil weist in bezug auf die Gewindeverbindung des zweiten Schraubdeckelteils mit dem gehäusefesten Gewinde entgesetzte Gangrichtung auf. Das Kanülenverschiebeteil weist eine Kupplung zur drehfesten Anbindung an den zweiten Schraubdeckelteil auf, um mit den axial aneinander festgesetzten ersten und zweiten Schraubdeckelteilen eine zusammengeschlossene Einheit zu bilden, die bei sich in Endstellung befindlicher Kanüle vom behälterfesten Gewinde abschraubbar ist. A particularly preferred embodiment of the actuator of the container according to the invention provides that the cannula in the e.g. by a patch on the container Needle holder formed container neck in the needle holder rotatably mounted, and that the actuator a plurality of coaxially arranged parts. These parts include a second screw cap part with its thread engages with a container-fixed thread, a first screw cap part, with the second screw cap part rotatably and axially fixedly connected, and a the cannula axially acting in the direction of the membrane Cannula displacement member threadedly engaged with the first screw cap part is located and for axial displacement of the Cannula by converting the rotational movement of the second screw cap part arranged in a lifting movement relative to this rotation is. The threaded connection between the first screw cap part and the cannula displacement member with respect to the Thread connection of the second screw cap part with the housing fixed Thread denuded gear direction. The cannula shifting part has a coupling for non-rotatable connection the second screw cap part on to the axially fixed to each other first and second screw cap parts a combined To form a unit which is in its final position Cannula can be unscrewed from the thread fixed to the container is.

Mit anderen Worten sieht eine bevorzugte Ausführungsform des erfindungsgemäßen Stelltriebs eine zweiteilige Ausbildung des Schraubdeckels vor, wobei ein zweiter Schraubdeckelteil die Funktion hat, den zweiteiligen Schraubdeckel so lange am Behälter zu halten, bis die Kanüle ihre Endstellung eingenommen hat, in welche sie die Membran durchstoßen hat, welche anfänglich die Behälteröffnung verschließt. Der erste Schraubdeckelteil hingegen ist frei drehbar und axial unverschieblich am zweiten Schraubdeckelteil gelagert und bildet das Antriebsmittel für ein Kanülenverschiebeteil, mit dem der Schraubdeckelteil im Gewindeeingriff steht. Diese Gewindeverbindung zwischen dem ersten Schraubdeckelteil und dem Kanülenverschiebeteil ist gegenläufig gebildet zu dem Gewinde, mit welchem der zweite Schraubdeckelteil am Behälter festgeschraubt ist, d.h. typischerweise mit einem Linksgewinde. Hierdurch wird erreicht, dass bei der normalen Aufschraubbewegung, d.h., durch Drehen des ersten Schraubdeckelteils im Gegenuhrzeigersinn (normale Deckelöffnungsdrehrichtung) der Kanülenhalter im Uhrzeigersinn unter Absenken der Kanüle angetrieben wird. Diese partiell drehmäßig festgesetzte Gewindeverbindung zum Umsetzen einer von außen angelegten Drehbewegung in eine axiale Hubbewegung des innen liegenden Kanülenverschiebeteils kann auch ersetzt sein durch eine Bajonettanordnung, die gleichzeitig Verriegelungsfunktion hat, oder durch Steilkurven, mit anderen Worten durch einen geeigneten Kulissenantrieb.In other words, a preferred embodiment of the actuator according to the invention a two-part design of the Screw cap before, with a second screw cap part the Function has the two-piece screw cap so long on the container hold until the cannula has reached its end position into which she has pierced the membrane, which initially the container opening closes. The first screw cap part however, is freely rotatable and axially immovable mounted on the second screw cap part and forms the drive means for a cannula sliding part with which the Screw cap part is in threaded engagement. This thread connection between the first screw cap part and the cannula displacement part is opposite to the thread, with which the second screw cap part screwed to the container is, i. typically with a left-hand thread. This ensures that in the normal Aufschraubbewegung, that is, by turning the first screw cap part in Counterclockwise (normal lid opening direction) of the Needle holder driven clockwise while lowering the cannula becomes. This partially rotationally fixed threaded connection for converting an externally applied rotary motion in an axial lifting movement of the inner cannula sliding part can also be replaced by a bayonet arrangement, which has simultaneous locking function, or by banked turns, in other words by a suitable one Scotch yoke.

Erst dann, wenn die Kanüle mittels des Kanülenverschiebeteils vollständig in ihre Endstellung überführt worden ist, wird ein Zusammenschluss der beiden Schraubdeckelteile mit dem Kanülenverschiebeteil bereitgestellt, so dass diese drei Teile gemeinsam wie eine einstückiger Schraubdeckel betätigt werden. D.h., diese zusammengeschlossene Schraubdeckeleinheit wird nunmehr bei einer weiteren Drehung im Gegenuhrzeigersinn wie ein herkömmlicher einteiliger Schraubdeckel durch Abschrauben vom Behälter von diesem gelöst. Nunmehr ist die fest in der Behälteröffnung sitzende Kanüle zur Abgabe des fließfähigen Mediums aus dem Behälter frei zugänglich.Only then, when the cannula by means of the cannula sliding part has been completely transferred to its final position is an association of the two screw cap parts with the cannula displacement part provided so that these three parts operated together like a one-piece screw cap. That is, this unified screw cap unit now turns counterclockwise with another turn like a conventional one-piece screw cap by unscrewing detached from the container of this. Now that is firmly seated in the container opening cannula for delivering the flowable medium freely accessible from the container.

Der Zusammenschluss der beiden Schraubdeckelteile mit dem Kanülenverschiebeteil ist bevorzugt auf Dauer ausgelegt, so dass diese insgesamt den Schraubdeckel bildenden Teile nunmehr stets wie ein normaler Schraubdeckel gehandhabt werden können.The merger of the two screw cap parts with the Kanülenverschiebeteil is preferably designed to last, so that this total the screw cap forming parts now always handled like a normal screw cap can.

Bevorzugt wird dem Nutzer des erfindungsgemäß gebildeten Deckels die Zweiteiligkeit des Schraubdeckels nicht offenbart; d.h., der Nutzer hat den Eindruck, einen normalen Schraubdeckel vor sich zu haben, da bevorzugt der erste Schraubdeckelteil den zweiten Schraubdeckelteil, der mit dem Behälter verschraubt ist, vollständig umschließt, so dass der Nutzer keine Veranlassung hat, den für ihn einzig zugänglichen ersten Schraubdeckelteil anders zu bedienen als einen normalen Schraubdeckel, nämlich durch Drehung im Gegenuhrzeigersinn, um ihn zu öffnen.The user of the lid formed according to the invention is preferred the bipartite of the screw cap not disclosed; that is, the user has the impression of a normal screw cap to have before, there preferably the first screw cap part the second screw cap part, with the container is screwed, completely enclosing, leaving the user There is no reason to have the only one accessible to him Screw cap part to operate differently than a normal one Screw cap, namely by counterclockwise rotation, to open it.

Die vorstehend erläuterte bevorzugte Ausführungsform des Stelltriebs für die Kanüle basiert auf einer drehfesten Lagerung der Kanüle im Behälterhals bzw. Kanülenhalter. Diese drehfeste Lagerung sieht bevorzugt einen Formschluss zwischen dem Kanülenhalter und der Kanüle vor. Die Kanüle weist hierzu vorteilhafterweise einen mehrkantigen Abschnitt auf, der einen entsprechend mehrkantigen Durchbruch im Kanülenhalter durchsetzt.The above-explained preferred embodiment of the Actuator for the cannula is based on a non-rotatable mounting the cannula in the container neck or cannula holder. This non-rotating bearing preferably sees a positive connection between the needle holder and the cannula in front. The cannula has this advantageously a polygonal section on which a corresponding polygonal breakthrough in the cannula holder interspersed.

Bevorzugt ist ferner vorgesehen, dass das behälterfeste Gewinde, mit welchem der zweite Schraubdeckelteil bis zum Abschrauben der zusammengeschlossenen Einheit der Deckelteile im Gewindeeingriff steht, ein am Behälterhals bzw. Kanülenhalter gebildetes Außengewinde ist.Preferably, it is further provided that the container-fixed thread, with which the second screw cap part until unscrewing the combined unit of the lid parts is in threaded engagement, an external thread formed on the container neck or cannula holder is.

Bevorzugt ist das Kanülenverschiebeteil vollständig im ersten Schraubdeckelteil enthalten und besitzt ein Außengewinde, das mit einem Innengewinde dieses Schraubdeckelteils im Eingriff steht. Zur drehfesten Lagerung des Kanülenverschiebeteils ist bevorzugt ein Formschluss zwischen diesem und der Kanüle vorgesehen. Dieser Formschluss sieht vorteilhafterweise einen mehrkantigen Kanülenabschnitt, z.B. denselben mehrkantigen Abschnitt, der auch die drehfeste Lagerung des Kanülenverschiebeteils bewirkt, vor, der mit Klemmorganen des Kanülenverschiebeteils im Eingriff steht. Da dieser Formschluss zum Abschrauben der zusammengeschlossenen Deckelteile-Kanülenverschiebeteilanordnung überwunden werden muss, nachdem die Kanüle ihre Endstellung eingenommen hat, ist vorgesehen, dass der Formschluss zum Abschrauben dieser zusammengeschlossenen Einheit vor allem durch nachgiebige Ausbildung der Klemmorgane des Kanülenverschiebeteils überwindbar gebildet ist.Preferably, the cannula shifting part is completely in the first Screw cap part included and has an external thread, with an internal thread of this Schraubdeckelteils in Intervention is. For non-rotatable mounting of the cannula sliding part is preferably a positive connection between this and the Cannula provided. This positive fit looks advantageous a polygonal cannula section, e.g. the same polygonal one Section, which is also the non-rotatable mounting of the cannula sliding part causes, before, with clamping organs of the cannula sliding part is engaged. Because this form fit for unscrewing the merged lid parts cannula slide member assembly must be overcome after the cannula has taken its end position is provided that the positive connection for unscrewing this merged Unity mainly through compliant education of Clamping elements of the cannula sliding part are made surmountable is.

Der Zusammenschluss der beiden Schraubdeckelteile mit dem Kanülenverschiebeteil erfolgt, wie vorstehend ausgeführt, über eine Kupplung zwischen dem Kanülenverschiebeteil und dem zweiten Schraubdeckelteil, die bevorzugt in Gestalt einer axial einrückbaren stirnverzahnung verwirklicht ist. Um den Zusammenschluss der zusammengeschlossenen Einheit dauerhaft zu gewährleisten, ist bevorzugt eine Einrichtung zum axialen Festsetzen des Kanülenschiebeteils am zweiten Schraubdeckelteil bei Eingriff der Kupplung zur drehfesten Verbindung dieser beiden Teile vorgesehen. Dieser Einrichtung zum axialen Festsetzen des Kanülenverschiebeteils am zweiten Schraubdeckelteil ist bevorzugt als Rastmittel gebildet. Dieses Rastmittel kann beispielsweise Haken bzw. Rastnasen am zweiten Schraubdeckelteil vorsehen, die in eine entsprechende Nut am Kanülenverschiebeteil eingreifen, um diese beiden Teile dauerhaft miteinander zu verbinden, wobei die dauerhafte Verbindung zwischen den beiden Schraubdeckelteilen durch die Drehverbindung dieser beiden Teil bereitgestellt wird, die eine Blockierungsstellung einnimmt, sobald der zweite Schraubdeckelteil dauerhaft mit dem Kanülenverschiebeteil verbunden ist; d.h., in diesem Zustand ist der erste Schraubdeckelteil nicht nur axial, sondern auch drehmäßig festgesetzt am zweiten Schraubdeckelteil.The merger of the two screw cap parts with the cannula shifting part takes place, as stated above a coupling between the cannula displacement part and the second Screw cap part, preferably in the form of an axial einrückbaren end gearing is realized. To the merger to assure the merged entity permanently, is preferably a device for axial setting the cannula pushing part on the second screw cap part upon engagement of the clutch for non-rotatable connection of this provided for both parts. This device for axial setting of the cannula sliding part on the second screw cap part is preferably formed as a locking means. This locking means can For example, hooks or latching lugs on the second screw cap part provide that in a corresponding groove on the cannula sliding part intervene to keep these two parts together permanently to connect, with the permanent connection between the two Schraubdeckelteilen by the rotary joint This two part is provided, which is a blocking position takes as soon as the second screw cap part permanently connected to the cannula shifting member; i.e., in this condition, the first screw cap part is not only axially, but also rotationally fixed on the second screw cap part.

Wie vorstehend ausgeführt, hat der erste Schraubdeckelteil bevorzugt die Gestalt eines üblichen Schraubdeckels, beispielsweise Becherform. In diesem Fall ist bevorzugt, dass das Kanülenverschiebeteil ebenfalls Becherform besitzt, und dass der allgemein zylindrische zweite Schraubdeckelteil sich an den Becherrand des Kanülenverschiebeteils anschließt. Die vorstehend genannten Klemmorgane, die mit dem mehrkantigen Kanülenabschnitt den Formschluss zwischen Kanüle und Kanülenverschiebeteil zur drehfesten Lagerung des Kanülenverschiebteils bilden, stehen vom Becherboden des Kanülenverschiebeteils in Gestalt einer Klemmbuchse vor, die mit ihren freien Enden im Eingriff mit dem mehrkantigen Kanülenabschnitt stehen. In diesem Fall ist außerdem bevorzugt vorgesehen, dass die freien Enden der Klemmbuchse einen Teller der Kanüle beaufschlagen, der in die Kanüle derart integriert ist, dass sein Ringrand radial vorsteht, um die Kanüle durch Drehbetätigung des ersten Schraubdeckelteils in ihre Endstellung in der Behälteröffnung absenken zu können. Anstelle der Klemmbuchse kann auch ein anderes Element verwendet werden, das eine drehfeste Lagerung für das Kanülenverschiebeteil gewährleistet und überdehnbar ist.As stated above, the first screw cap part has prefers the shape of a conventional screw cap, for example Cup shape. In this case, it is preferable that the cannula sliding part also has a cup shape, and that the generally cylindrical second Schraubdeckelteil itself adjoins the cup rim of the cannula sliding part. The above-mentioned clamping members, with the polygonal Cannula section the positive connection between the cannula and cannula displacement part for non-rotatable mounting of the cannula sliding part form, stand from the cup bottom of the cannula shift part in the form of a clamping bush in front, with their free Ends are engaged with the polygonal cannula portion. In this case, it is also preferred that the free ends of the clamping bush act on a plate of the cannula, which is integrated into the cannula such that its annular rim projects radially to the cannula by rotary actuation of the first screw cap part in its end position in to be able to lower the container opening. Instead of the clamping bush can also be used another element that ensures a rotationally fixed storage for the cannula sliding part and is over-stretchable.

In Fig. 1 ist der Behälter zur Aufnahme und Abgabe eines fließfähigen Mediums, vor allem von Klebstoff allgemein mit der Bezugsziffer 10 bezeichnet. Der zum Verschluss des Behälters dienende mehrteilige Schraubdeckel ist allgemein mit der Bezugsziffer 11 bezeichnet. Der Behälter 10 umfasst einen das fließfähige Medium enthaltenden Innenbehälter 12, der in nicht näher dargestellter Weise mit einem Außenbehälter 13 fest und luftdicht verbunden ist. Anstelle eines Innenbehälters und eines Außenbehälters kann auch in herkömmlicherweise ein einziger Behälter zur Aufnahme eines flüssigen Mediums vorgesehen sein. Bei der dargestellten Anordnung bildet der Innenbehälter 12, wie bereits angeführt, das Aufnahmegefäß für das fließfähige Medium, während der Außenbehälter 13 mit dem Innenbehälter 12 unter Zwischenanordnung eines Luftkissens verbunden ist, über welchen der Innenbehälter 12 zur Abgabe von fließfähigem Medium indirekt zusammengedrückt werden kann.In Fig. 1, the container for receiving and delivering a flowable medium, especially of glue in general with the reference numeral 10 denotes. The to the closure of the container serving multi-part screw cap is common with the Reference numeral 11 denotes. The container 10 comprises a flowable medium containing inner container 12, the in not shown manner with an outer container 13th firmly and airtight is connected. Instead of an inner container and an outer container can also in conventional a single container for receiving a liquid medium be provided. In the illustrated arrangement forms the Inner container 12, as already stated, the receptacle for the flowable medium, while the outer container 13 with the inner container 12 with the interposition of an air cushion is connected, over which the inner container 12 for dispensing be compressed indirectly by flowable medium can.

Der mehrteilige Schraubdeckel 11 umfasst einen zylindrischen, becherförmigen Außendeckel 14, der den eigentlichen Schraubdeckel des Behälters 10 vollständig umschließt und zusammen mit diesem eine Kindersicherung bereitstellt, die im folgenden näher erläutert ist.The multi-part screw cap 11 comprises a cylindrical, cup-shaped outer lid 14, the actual screw cap completely encloses the container 10 and together With this one provides a child safety, in the following is explained in more detail.

Der Außendeckel 14 soll einen nicht autorisierten Zugriff auf den innenliegenden Schraubdeckel durch Kinder verhindern. Zu diesem Zweck ist er mit dem innenliegenden Schraubdeckel frei drehbar verbunden und ein Zusammenschluss mit dem innenliegenden Schraubdeckel zur Betätigung desselben erfolgt in an sich bekannter Weise durch eine axiale Verschiebung des Außendeckels 14 gegen den innenliegenden Schraubdeckel unter Zusammenschluss mit diesem.The outer lid 14 is intended to unauthorized access prevent the inside screw cap by children. To For this purpose it is free with the inside screw cap rotatably connected and a merger with the inside Screw cap for operating the same takes place in known manner by an axial displacement of the outer cover 14 against the inner screw under Merger with this.

In Fig. 1 ist von dem innenliegenden Schraubdeckel ein ebenfalls becherförmig gebildeter erster Schraubdeckelteil 15 zu erkennen, dessen Außendurchmesser auf den Innendurchmesser des Außendeckels 14 derart abgestimmt ist, dass der Außendeckel 14 relativ zum ersten Schraubdeckelteil frei drehbar ist. Zur unlösbaren axialen Halterung des Außendeckels 14 am ersten Schraubdeckelteil 15 umfasst dieser eine Ringnut 16, die bei der dargestellten Ausführungsform im Bereich des Becherrands des becherförmigen Schraubdeckelteils 15 gebildet ist. Zum Eingriff in die Ringnut 16 ist an der Innenwandung des Außendeckels 14 eine umlaufende ringförmige Nocke 17 gebildet. Die Nocke 17 hat eine geringere axiale Erstreckung als die Ringnut 16, so dass der Außendeckel 14 axial verschiebbar entsprechend der Höhe der Ringnut 16 auf dem ersten Schraubdeckelteil 15 sitzt, mit diesem jedoch über den Ringnut-/Nockeneingriff untrennbar verbunden ist.In Fig. 1 of the inner screw cap is also a cup-shaped first screw cap part 15 too recognize its outer diameter on the inner diameter the outer lid 14 is tuned such that the outer lid 14 freely rotatable relative to the first screw cap part is. For permanent axial retention of the outer cover 14 on first screw cap part 15 comprises an annular groove 16, in the illustrated embodiment in the region of the cup rim the cup-shaped screw cap part 15 is formed is. To engage in the annular groove 16 is on the inner wall the outer lid 14, a circumferential annular cam 17 is formed. The cam 17 has a smaller axial extent as the annular groove 16, so that the outer cover 14 axially displaceable according to the height of the annular groove 16 on the first Screw cap 15 sits, but with this over the Ringnut- / cam engagement is inseparable.

An den Boden des ersten Schraubdeckelteils 15 ist ein Federmittel in Gestalt eines allgemein U-förmigen, auswärts vorspringenden Stegs 18 einstückig mit dem Boden gebildet. Dieser Federsteg besteht aus elastischem Material, bevorzugt aus demselben Kunststoffmaterial, aus welchem auch der erste Schraubdeckelteil 15 gebildet ist. Der allgemein bogenförmige Federsteg 18 ist derart geformt, dass er im entspannten Zustand durch Anlage gegen die Innenseite des Bodens 19 des Außendeckels 14 dessen ringförmige Nocke 17 gegen den oberen Rand der Ringnut 16 im ersten Schraubdeckelteil hält.At the bottom of the first screw cap part 15 is a spring means in the form of a generally U-shaped, outwardly projecting Bridge 18 is formed in one piece with the ground. This Spring bar is made of elastic material, preferably made of the same plastic material, from which also the first Screw cap part 15 is formed. The generally arcuate Spring bar 18 is shaped so that it is in the relaxed state by abutment against the inside of the bottom 19 of the outer cover 14 whose annular cam 17 against the upper Edge of the annular groove 16 holds in the first screw cap part.

Zwischen den Böden des Außendeckels 14 und des ersten Schraubdeckelteils 15 ist ein Kupplungsmittel in Gestalt eines schraubdeckelteilseitigen Zahnkranzes 20 und eines außendeckelseitigen Zahnkranzes 21 gebildet. Diese beiden Zahnkränze 20 und 21 besitzen dieselbe Zahnabfolge und Zahnhöhe, und die Zahnhöhe ist derart gebildet, dass die beiden Zahnkränze 20 und 21 durch Einwirkung des Federstegs 18 nicht in Eingriff gelangen, solange auf den Außendeckel 14 keine axiale Kraft angewendet wird, die ausreicht, die dem Federsteg 18 eigene Bogenform zu überwinden und die Zahnkränze 20 und 21 in Eingriff miteinander zu bringen. In dieser eingerückten Stellung der durch die Zahnkränze 20, 21 bereitgestellten Kupplung zwischen dem Außendeckel 14 und dem ersten Schraubdeckelteil 15 (s. Fig. 4) befindet sich die Nocke 17 des Außendeckels 14 im Bereich des unteren Rands der Ringnut 16. Alternativ kann anstelle der Ringnut 16 ein durchgehend durchmesserverringerter Becherrandbereich des ersten Schraubdeckelteils 15 vorgesehen sein, wobei in diesem Fall die Nocke 17 an der Schulter zwischen den beiden durchmesserunterschiedlichen Teilen des ersten Schraubdeckelteils 15 durch Federkraft zur Anlage gelangt, wenn auf den Außendeckel 15 keine axiale abwärts gerichtete Kraft ausgeübt ist.Between the bottoms of the outer cover 14 and the first Schraubdeckelteils 15 is a coupling agent in the form of a screw cover side sprocket 20 and an outer cover side Sprocket 21 formed. These two sprockets 20 and 21 have the same tooth sequence and tooth height, and the tooth height is formed such that the two sprockets 20 and 21 by the action of the spring bar 18 not in Engage as long as on the outer cover 14 no axial Force is applied, which is sufficient to the spring bar 18 own arc shape to overcome and the sprockets 20 and 21 in engagement with each other. In this indented Position of the provided by the sprockets 20, 21 Coupling between the outer cover 14 and the first Screw cap part 15 (see Fig. 4) is the cam 17th of the outer cover 14 in the region of the lower edge of the Annular groove 16. Alternatively, instead of the annular groove 16 a continuous diameter-reduced cup rim area of the be provided first screw cover 15, wherein in this Drop cam 17 at the shoulder between the two diameter-different parts of the first screw cap part 15 comes to rest by spring force when on the outer lid 15 no axial downward force exerted is.

Eine Betätigung des eigentlichen Schraubdeckels über den Außendeckel 14 ist also nur möglich, indem an den Außendeckel 14 nicht nur eine Drehbewegung sondern auch eine abwärts gerichtete axiale Kraft ausgeübt wird, wodurch in herkömmlicherweise eine Kindersicherung bereitgestellt ist.An actuation of the actual screw cap on the Outer cover 14 is thus possible only by the outer cover 14 not only a rotary motion but also a downward axial force is applied, which in conventional a child safety lock is provided.

Als weitere Sicherheitsmaßnahme ist vorgesehen, wie aus Fig. 1 hervorgeht, dass der Becherrand 22 innerhalb eines ringförmigen Kragens 23 zu liegen kommt, der in Art eines Flansches mit dem Außenbehälter 13 bzw. dem daran angeordneten Schraubdeckel adapter 36 fest verbunden ist. Die freie Höhe des Kragens 23 ist so gewählt, dass der Außendeckel 14 ungehindert niedergedrückt werden kann, ohne durch den Kragen 23 an dieser Hubbewegung behindert zu werden. Andererseits erstreckt sich der Kragen 23 vom Außenbehälter 13 soweit axial nach oben, dass der Becherrand 22 auch dann innerhalb des Kragens 23 zu liegen kommt, wenn der Außendeckel 14 axial unbelastet ist, wie in Fig. 1 gezeigt. As a further security measure is provided, as shown in FIG. 1 shows that the cup rim 22 within an annular Kragen's 23 comes to rest in the manner of a flange with the outer container 13th or arranged thereon screw cap adapter 36 is firmly connected. The free height of the collar 23 is chosen so that the outer cover 14 unhindered can be depressed without going through the collar 23 to be hindered in this lifting movement. on the other hand the collar 23 extends axially from the outer container 13 to the top, that the cup rim 22 also within the Collar 23 comes to rest when the outer cover 14 axially is unloaded, as shown in Fig. 1.

Wie aus der Schnittdarstellung von Fig. 2 hervorgeht, umschließt der becherförmige erste Schraubdeckelteil 15 einwärts liegend von seinem Becherrand einen zweiten Schraubdeckelteil 24 und einen zwischen diesem und dem Boden des ersten Schraubdeckelteils 15 angeordnetes Kanülenverschiebeteil 25 zur axialen Betätigung einer Kanüle 26, die in Fig. 4 in einer Ausgangsstellung gezeigt ist, in welcher sie mit ihrem unteren Ende unter Abstand über einer Membran 27 zu liegen kommt, welche die Behälteröffnung des Innenbehälters 12 in Gestalt eines rohrförmigen Behältereinsatzes 28 vor der ersten Nutzung des Behälters verschließt.As is apparent from the sectional view of Fig. 2, encloses the cup-shaped first screw cap part 15 inwards lying from his cup rim a second screw cap part 24 and one between this and the bottom of the first Schraubdeckelteils 15 arranged Kanülenverschiebeteil 25 for the axial actuation of a cannula 26, the in Fig. 4 in a starting position is shown, in which she with her lower end at a distance above a membrane 27 to lie comes, which the container opening of the inner container 12 in Shape of a tubular container insert 28 before the first Use of the container closes.

Wie aus Fig. 2, 3 und 4 hervorgeht, besitzt der zweite Schraubdeckelteil 24 Zylinderform und einen Außendurchmesser in etwa entsprechend dem Innendurchmesser des ersten Schraubdeckelteils 15, in welchem er drehbar und axial unverschieblich geführt ist. Zu diesem Zweck ist am Unterrandbereich des zweiten Schraubdeckelteils 24 eine Ringnut 29 gebildet, in die eine von der Innenwandung des ersten Schraubdeckelteils 15 vorstehende Wulst bzw. ringförmige Nocke 30 vorsteht. Um den Zusammenbau des zweiten Schraubdeckelteils 24 mit dem ersten Schraubdeckelteil 15 zu erleichtern, demnach der zweite Schraubdeckelteil 24 über den offenen Becherrand des ersten Schraubdeckelteils 15 in diesen eingeschoben wird, bis die ringförmigen Nocke 30 des ersten Schraubdeckelteils 15 in der Ringnut 29 des zweiten Schraubdeckelteils 24 zu liegen kommt, ist in Montagerichtung vor der Ringnut 29 eine konusförmige Wulst 31 am Außenumfang des zweiten Schraubdeckelteils 24 gebildet, die in montiertem Zustand in einer hierzu komplementär gebildeten umlaufenden ringförmigen Nut 32 zu liegen kommt, die in der Innenwandung des ersten Schraubdeckelteils 15 gebildet ist.As is apparent from Fig. 2, 3 and 4, the second has Screw cap part 24 cylindrical shape and an outer diameter approximately corresponding to the inner diameter of the first Screw cap part 15, in which he rotatable and axially immovable is guided. For this purpose is at the lower edge area the second screw cap part 24 an annular groove 29 is formed, in the one of the inner wall of the first screw cap part 15 projecting bead or annular cam 30 protrudes. To the assembly of the second screw cap part 24th to facilitate with the first screw cap 15, accordingly the second screw cap part 24 over the open cup rim of the first screw cap part 15 inserted into this is until the annular cam 30 of the first screw cap part 15 in the annular groove 29 of the second screw cap part 24 comes to rest is in the mounting direction in front of the annular groove 29th a cone-shaped bead 31 on the outer periphery of the second screw cap part 24 formed in the assembled state in one For this complementary formed circumferential annular groove 32 comes to rest in the inner wall of the first Screw cap part 15 is formed.

Wie in Fig. 4 gezeigt, steht der zweite Schraubdeckelteil 24 bei auf dem Behälter 10 aufgeschraubtem Schraubdeckel 11 mit einem Innengewinde 33, das als Rechtsgewinde gebildet ist, im Eingriff mit einem behälterfesten Außengewinde 34, das an der Außenseite eines becherförmigen Kanülenhalters 35 gebildet ist, der den zentralen Teil eines Schraubdeckeladapters 36 bildet, welcher fest mit dem Außenbehälter 13 verbunden ist und integral den vorstehend erläuterten Kragen 23 umfasst, der bei aufgeschraubtem Schraubdeckel 11 den Becherrand 22 des Außendeckels 14 übergreift. Der Kanülenhalter 35 besitzt in seinem Boden einen zentralen Vierkantdurchbruch 37, der von einem entsprechenden Vierkantabschnitt 38 der Kanüle 26 durchgriffen ist, die zu ihrem Vorderende hin konisch verjüngt ausläuft und die am anderen Ende einen messerschneidenartig gebildeten Rand 39 zum Durchstoßen der Membran 27 besitzt.As shown in FIG. 4, the second screw cap part 24 stands with screwed onto the container 10 screw 11 with an internal thread 33, which is formed as a right-hand thread, in Engagement with a container-fixed external thread 34, which at the Outside of a cup-shaped cannula holder 35 is formed is the central part of a screw cap adapter 36th forms, which is firmly connected to the outer container 13 and integrally comprises the collar 23 explained above, when screwed screw 11, the cup rim 22nd the outer lid 14 overlaps. The cannula holder 35 has in its bottom a central square breakthrough 37, that of a corresponding square section 38 of the cannula 26 is tapered, which tapers conically towards its front end runs out and at the other end a knife-edge-like formed edge 39 for piercing the membrane 27 has.

Etwa auf halber Erstreckungslänge umfasst die Kanüle 26 einen Teller 40, der mit seinem Ringrand radial von der Außenseite der Kanüle 26 vorsteht und einen axialen Anschlag für die Kanüle 26 bildet, der bei vollständig in eine Endstellung abgesenkter Kanüle 26 zur Anlage auf der Außenseite des Bodens des becherförmigen Kanülenhalters 35 gelangt. In dieser Endstellung ist die Kanüle 26 durch nicht dargestellte Rastmittel mit dem Kanülenhalter 35 dauerhaft verrastet.Approximately half the extension length, the cannula 26 includes a Plate 40, with its ring edge radially from the outside the cannula 26 protrudes and an axial stop for the cannula 26 forms, which when fully lowered into an end position Cannula 26 to rest on the outside of the floor the cup-shaped cannula holder 35 passes. In this end position is the cannula 26 by not shown locking means permanently locked with the needle holder 35.

Das Kanülenverschiebteil 25 dient zur Überführung der Kanüle 26 aus ihrer in Fig. 4 gezeigten Ausgangsstellung, in welcher sich die Kanüle 26 unter Abstand über der Membran 27 befindet, in die in Fig. 5 gezeigte Endstellung, in der die Kanüle 26 die Membran 27 durchstoßen hat und in der Behälteröffnung zu liegen kommt. Angetrieben wird das Kanülenverschiebeteil 25 über den ersten Schraubdeckelteil 15 bzw. den mit diesem zusammengeschlossenen Außendeckel 14 durch Drehung im Gegenuhrzeigersinn. Um diese Drehbewegung in eine axiale Verstellbewegung für die Kanüle 26 umzusetzen, steht das Kanülenverschiebeteil 25 im Gewindeeingriff mit dem ersten Schraubdeckelteil 15. Zu diesem Zweck besitzt das Kanülenverschiebeteil 25 auf seinem Außenumfang ein Außengewinde 41, das im Eingriff steht mit einem Innengewinde 42 auf der Innenseite des ersten Schraubdeckelteils 15. Die Anordnung aus Außengewinde 41 und Innengewinde 42 hat einen entgegengesetzten Gangverlauf zu der Anordnung aus Innengewinde 33 und Außengewinde 34; d.h., im vorliegenden Fall sind das Außengewinde 41 und das Innengewinde 42 als Linksgewinde gebildet.The cannula displacement part 25 serves to transfer the cannula 26 from its initial position shown in Fig. 4, in which the cannula 26 is at a distance above the membrane 27, in the end position shown in Fig. 5, in which the cannula 26 has pierced the membrane 27 and in the container opening to come to rest. The cannula displacement part is driven 25 on the first screw cap part 15 and with this joined outer cover 14 by rotation in the counterclockwise direction. To this rotational movement in an axial adjustment to implement for the cannula 26, is the Kanülenverschiebeteil 25 in threaded engagement with the first screw cap part 15. For this purpose has the cannula shifting part 25 on its outer circumference, an external thread 41, the in Engagement is with an internal thread 42 on the inside of the first screw cap part 15. The arrangement of external thread 41 and internal thread 42 has an opposite Gang course to the arrangement of internal thread 33 and external thread 34; that is, in the present case, the external threads 41 are and the internal thread 42 formed as a left-hand thread.

Um das Drehen des ersten Schraubdeckelteils 15 (über den Außendeckel 14) im Gegenuhrzeigersinn in eine axiale Hubbewegung zum Absenken des Kanülenverschiebeteils 25 und damit der Kanüle 26 über die Außen- und Innengewinde 41, 42 umzusetzen, ist das Kanülenverschiebeteil 25 drehfest an der Kanüle 26 gelagert. Diese drehfeste Verbindung wird bereitgestellt durch eine vierkantige Klemmbuchse 43, die an die Innenseite des Bodens des becherförmigen Kanülenverschiebeteils 25 fest angebunden ist, und in Fig. 4 als Schnittdarstellung gezeigt ist. Die Klemmbuchse 43 ist bevorzugt einstückig mit dem Kanülenverschiebeteil 25 gebildet, besitzt einen rechteckigen Querschnitt und liegt an dem Vierkantabschnitt 38 der Kanüle 26 an. Durch diesen Formschluss zwischen der Klemmbuchse 43 und dem Vierkantabschnitt 38 der Kanüle 26 ist der drehfeste Sitz des Kanülenverschiebeteils 25 gewährleistet. D.h., ein Drehen des ersten Schraubdeckelteils 25 im Gegenuhrzeigersinn (über den Außendeckel 14) wird in eine Verschiebung des Kanülenverschiebeteils 25 nach unten in Richtung auf den Behälter 10 umgesetzt. Da die Klemmbuchse 43 so lang gebildet ist, dass sie auf der Oberseite des Ringstegs 40 zu liegen kommen, wird diese abwärts gerichtete Hubbewegung des Kanülenverschiebeteils 25, ausgelöst durch ein Drehen des ersten Schraubdeckelteils 15 im Gegenuhrzeigersinn umgesetzt in eine axiale Verschiebung der Kanüle 26 aus ihrer Anfangsstellung in die Endstellung, wobei das Messerschneidenende 39 der Kanüle 26 im Lauf dieser Absenkbewegung die Membran 27 durchstößt.To turn the first screw cap part 15 (over the outer lid 14) in an anti-clockwise direction in an axial stroke movement for lowering the cannula displacement part 25 and thus the To implement cannula 26 via the external and internal threads 41, 42, the cannula displacement part 25 is rotationally fixed to the cannula 26 stored. This non-rotatable connection is provided by a four-sided clamping bush 43, which is attached to the inside the bottom of the cup-shaped cannula displacing part 25 is connected, and shown in Fig. 4 as a sectional view is. The clamping bush 43 is preferably integral with the cannula displacement part 25 formed, has a rectangular cross-section and abuts the square section 38 of the cannula 26 at. Through this positive connection between the clamping bush 43 and the square section 38 of the cannula 26 is the non-rotatable seat the cannula displacement part 25 ensures. That is, a turn of the first screw cap part 25 in the counterclockwise direction (via the outer cover 14) is in a displacement of the cannula sliding part 25 down in the direction of the container 10th implemented. Since the clamping bush 43 is formed so long that they come to rest on the top of the ring land 40 is this downward stroke movement of the cannula sliding part 25, triggered by turning the first screw cap part 15 counterclockwise converted into an axial Displacement of the cannula 26 from its initial position in the End position, wherein the knife cutting end 39 of the cannula 26th in the course of this lowering movement the membrane 27 pierces.

Wie aus Fig. 3 hervorgeht, ist am oberen Rand des zylindrischen zweiten Schraubdeckelteils 24 ein in axialer Richtung vorstehender Zahnkranz 45 gebildet, der zum Eingriff mit einem komplementär gebildeten Zahnkranz 46 bestimmt ist, der vom Becherrand des becherförmigen Kanülenverschiebeteils 25 axial vorsteht. Die Zahnkränze 45 und 46 gelangen in gegenseitigen Eingriff, wenn das Kanülenverschiebeteil 25 die Kanüle 26 in ihre Endstellung abgesenkt hat. Aufgrund dieses kupplungsartigen Eingriffs zwischen den beiden Zahnkränzen 45 und 46 führt dann eine weitere Drehung des ersten Schraubdeckelteils 15 (über den Außendeckel 14) im Gegenuhrzeigersinn zu einem Abschrauben des zweiten Schraubdeckelteils 24, das mit seinem Innengewinde 33 im Eingriff mit dem Außengewinde 34 des behälterfesten Kanülenhalters 35 steht. Auf diese Weise wird die Anordnung aus erstem Schraubdeckelteil 15 (und Außendeckel 14), zweitem Schraubdeckelteil 24 und Kanülenverschiebeteil, die nunmehr sämtlich drehfest zusammengeschlossen sind, also der gesamte Schraubdeckel 11 vom Behälter 10 abgeschraubt, wodurch, wie in Fig. 6 gezeigt, der Schraubdeckel 11 schließlich vom Behälter 10 freikommt, wodurch die Kanüle 26 zur bestimmungsgemäßen Abgabe von fließfähigem Medium aus dem Innenbehälter 12 zur Verfügung steht.As is apparent from Fig. 3, is at the upper edge of the cylindrical second screw cap part 24 in the axial direction protruding ring gear 45 is formed, which is for engagement with a Complementarily formed sprocket 46 is determined, the from the cup rim of the cup-shaped cannula displacement part 25 projects axially. The sprockets 45 and 46 arrive in mutual Intervention when the cannula shifting part 25, the cannula 26 has lowered to its final position. Because of this clutch-like engagement between the two sprockets 45th and 46 then performs another rotation of the first screw cap part 15 (over the outer cover 14) in a counterclockwise direction to unscrew the second screw cap part 24, the with its internal thread 33 in engagement with the external thread 34 of the container-fixed needle holder 35 stands. In this way the arrangement of the first screw cap part 15 (and Outer cover 14), second screw cover part 24 and cannula sliding part, now all together rotatably connected are, so the entire screw 11 from the container 10th unscrewed, whereby, as shown in Fig. 6, the screw cap 11 finally released from the container 10, whereby the Cannula 26 for the intended delivery of flowable medium from the inner container 12 is available.

Um diesen Zusammenschluss der einzelnen Deckelteile mit dem Kanülenverschiebeteil dauerhaft und unlösbar zu sichern, ist zwischen dem Kanülenverschiebeteil 24 und dem ersten Schraubdeckelteil 24 ein Rastverbindung vorgesehen.To this merger of the individual cover parts with the Securing cannula shifting part permanently and permanently is between the cannula shifting part 24 and the first screw cap part 24 provided a latching connection.

Wie insbesondere aus Fig. 3 und Fig. 4 hervorgeht, umfasst diese Rastverbindung eine Vielzahl von einander gegenüberliegenden Rasthaken (in Fig. 3 sind insgesamt drei dieser Rasthaken 47, 48, 49 zu erkennen), die axial von der Oberseite des zylindrischen zweiten Schraubdeckelteils 24 vorstehen und bei vollständig abgesenktem Kanülenverschiebeteil 25 in eine umlaufende Ringnut 50 eingreifen, die an der Innenwandung des Kanülenverschiebeteils 25 gebildet ist.As can be seen in particular from FIG. 3 and FIG. 4 this locking connection a variety of opposing Latch hook (in Fig. 3 are a total of three of these locking hooks 47, 48, 49) which are axially from the top of the cylindrical second screw cap part 24 protrude and at completely lowered cannula sliding part 25 in a circumferential annular groove 50 engage, which on the inner wall of the Cannula displacement part 25 is formed.

Sobald die Rasthaken 47 bis 49 in die Ringnut 50 eingerückt sind, ist das Kanülenverschiebeteil 25 drehfest und axial untrennbar mit dem zweiten Schraubdeckelteil 24 verbunden. Andererseits ist in diesem Zustand der erste Schraubdeckelteil 15 über die Gewindeanordnung 41, 42 drehfest mit dem Verbund aus Kanülenverschiebeteil 25 und zweitem Schraubdeckelteil 24 verbunden, so dass diese drei Teile 24, 25 und 15 nunmehr reine Deckelfunktion haben, also den Schraubdeckel 11 festlegen, der über die Kindersicherung per Außendeckel 14 betätigbar ist, dessen Schraub-Drehverstellung nun jedoch nicht mehr zu einer Betätigung des Kanülenverschiebeteils 25 führt.Once the locking hooks 47 to 49 are engaged in the annular groove 50 are, the Kanülenverschiebeteil 25 is rotationally fixed and axially inseparable connected to the second screw cap part 24. on the other hand is in this state the first screw cap part 15 via the thread assembly 41, 42 against rotation with the composite from cannula shifting part 25 and second screw cap part 24 connected so that these three parts 24, 25 and 15 now have a pure lid function, so set the screw 11, the via the child safety by outer cover 14 actuated is, whose screw-turning adjustment, however, no longer leads to an actuation of the cannula displacement part 25.

Von der Innenseite des Bodens des becherförmigen Kanülenverschiebeteils 25 steht zentral ein Verschlusszapfen 51 vor, der für die Austragöffnung der Kanüle 26 die Funktion eines Verschlussmittels hat und zwar sowohl dann, wenn sich die Kanüle 26 in ihrer Ausgangsstellung befindet, wie dann, wenn sie sich in ihrer Endstellung befindet.From the inside of the bottom of the cup-shaped cannula displacement part 25 is centrally a closure pin 51, for the discharge of the cannula 26, the function of a Closure means and that both when the cannula 26 is in its initial position, as if, when she is in her final position.

Eine bevorzugte Besonderheit des Vierkantabschnitts 38 der Kanüle 26 besteht darin, dass dieser Abschnitt dort, wo er im Eingriff mit der Klemmbuchse 43 des Kanülenverschiebeteils 25 steht, verrundete Kanten aufweist, um den zusammengeschlossenen Verbund aus den beiden Schraubdeckelteilen 15 und 24 und dem Kanülenverschiebeteil 25 ohne übermäßigen Widerstand vom Behälter abschrauben zu können, wenn die Kanüle 26 in ihre Endstellung überführt ist. In dieser Situation kommt es aufgrund des Zusammenschlusses dieser Teile zu einer Relativdrehung zwischen der dabei eine Überdrehung erfahrenden Klemmbuchse 43 und dem Vierkantabschnitt 38 der Kanüle 26, und dieser Klemmwiderstand wird dadurch verringert, dass der Vierkantabschnitt 38 oberhalb des Ringstegs 40 im Kantenbereich verrundet ist. A preferred feature of the square section 38 of the Cannula 26 is that this section where it is in Engagement with the clamping bush 43 of the cannula displacement part 25th stands, rounded edges around the merged Composite of the two screw cap parts 15 and 24 and the cannula displacement part 25 without excessive resistance from To unscrew container when the cannula 26 in her End position is transferred. In this situation it comes because of the merger of these parts to a relative rotation between the case of an over-rotation experienced clamping bush 43 and the square section 38 of the cannula 26, and This clamping resistance is reduced by the fact that Square section 38 above the annular ridge 40 in the edge region rounded.
