Description

Die Erfindung betrifft eine aus Kunststoff oder Metall gefertigte Tube, deren Tubenhals mündungsseitig mit einer Membrane verschlossen ist und die zum Aufschrauben einer aus Kunststoff gefertigten Verschlußkappe ein Gewinde aufweist, wobei in der äußeren oder inneren Verschlußkappen-Stirnfläche ein Dorn zum Durchdrücken dieser Membrane vorgesehen ist.The invention relates to a tube made of plastic or metal, the tube neck is closed on the mouth side with a membrane and which has a thread for screwing on a plastic closure cap, a mandrel being provided in the outer or inner end face of the cap for pushing through this membrane.

Die den Tubenhals verschließende Membrane soll dazu dienen, den Tubeninhalt bis zum Öffnen der Tube keimfrei zu verschließen. Damit können sowohl bei Luftzutritt schnell verderbliche Füllungen über einen längeren Zeitraum aufbewahrt, wie auch beispielsweise Arzneimittel steril gehalten werden. Das Öffnen der Tube erfolgt im allgemeinen durch einen im Schraubverschluß vorgesehenen Dorn, mit dem die Membrane in das Tubeninnere hinein durchgedrückt werden kann. Dieser Dorn ist üblicherweise im Kopf des Schraubverschlusses untergebracht, um den Schraubverschluß fest auf den Tubenhals aufschrauben, die empfindliche Membrane damit also auch gegen mechanischen Angriff schützen zu können. Es besteht jedoch auch die Möglichkeit, den Dorn im Inneren des Schraubverschlusses unterzubringen, wobei jedoch Maßnahmen vorzusehen sind, um ein ungewolltes Eindrücken der Membrane beim Aufschrauben des Schraubverschlusses zu verhindern.The membrane closing the tube neck is intended to do this serve to seal the tube contents until they open the tube. This means that both perishable fillings can be stored over a longer period of time, as well as medicinal products can be kept sterile, for example, when air enters. The tube is generally opened by means of a mandrel provided in the screw closure, with which the membrane can be pushed into the interior of the tube. This mandrel is usually housed in the head of the screw cap in order to screw the screw cap firmly onto the tube neck, so that it can also protect the sensitive membrane against mechanical attack. However, there is also the possibility of accommodating the mandrel in the interior of the screw cap, although measures must be taken to prevent the membrane from being pressed in unintentionally when the screw cap is screwed on.

Bei diesen bekannten Tubenausführungen wird es als nachteilig empfunden, daß die Membrane in das Innere der Tube hineingedrückt wird, da dadurch Teile dieser durchgedrückten Membrane mit dem Tubeninhalt wieder austreten oder sich zumindest zurückstellen und damit zu Unannehmlichkeiten führen können.In these known tube designs, it is felt to be disadvantageous that the membrane is pressed into the interior of the tube, since parts of this pressed membrane with the tube contents emerge again or at least reset and can thus lead to inconvenience.

Aufgabe der Erfindung ist es daher, eine Tube mit Schraubverschluß zu schaffen, deren Tubenhals zwar in bekannter und bewährter Weise durch eine Membrane verschlossen ist, die jedoch so zu öffnen ist, daß die Membrane nicht in das Innere der Tube hineingedrückt wird.The object of the invention is therefore to provide a tube with a screw closure, the tube neck of which is closed in a known and proven manner by a membrane, but which can be opened such that the membrane is not pressed into the interior of the tube.

Erreicht wird dies nach der Erfindung dadurch, daß der Dorn ein Hohldorn ist, dessen Außendurchmesser etwa der Tubenhalsweite entspricht und daß die ringförmige Stirnkante dieses Hohldorns als Schneidkante ausgebildet ist, die auch kronenförmig ausgezackt sein kann. Die Membrane kann, je nach Tubenausführung, aus Kunststoff oder aus Metall gebildet sein. Diese Membrane wird nun durch den Hohldorn nach der Erfindung von der Tubenhalswandung abgedrängt, wobei sich eine Stauchung des Membranmaterials ergibt, was zu einer Aufbauchung der Membranplatte in das Innere des Hohldorns hinein führt. Die dadurch im Membranmaterial erzeugte Spannung drückt das abgetrennte Membranplättchen an die Innenwandung des Hohldorns, so daß es dort fest gehalten ist. Da außerdem der Außendurchmesser des Hohldorns mit dem-Innendurchmesser des Tubenhalses erfindungsgemäß übereinstimmen soll, wird die Membrane so sauber abgeschnitten, daß zum einen die volle lichte Weite der Tubenaustrittsöffnung zum Ausdrücken der in der Tube eingefüllten Masse zur Verfügung steht und zum anderen keine weggedrückten oder abgerissenen Membranteile mehr mit der Masse austreten können. Hiermit ist nicht nur die gestellte Aufgabe, wonach die Membrane nicht mehr in das Innere der Tube hineingedrückt werden soll, gelöst, sondern es ist auch.dafür gesorgt, daß das Ausdrücken der in der Tube eingefüllten Masse über den vollen lichten Querschnitt der Tubenaustrittsöffnung erfolgen kann und auch, daß sich am Tubenhals durch in den Tubenhals hineinstehende Membranteile . keine "toten Ecken", hinter denen sich erhärtender Tubeninhalt festsetzen könnte bilden.This is achieved according to the invention in that the mandrel is a hollow mandrel, the outer diameter of which corresponds approximately to the tube neck width and in that the annular end edge of this hollow mandrel is designed as a cutting edge, which can also be serrated in a crown shape. Depending on the tube version, the membrane can be made of plastic or metal. This membrane is now pushed away from the tube neck wall by the hollow mandrel according to the invention, resulting in compression of the membrane material, which leads to a bulging of the membrane plate into the interior of the hollow mandrel. The resulting tension in the membrane material presses the separated membrane plate against the inner wall of the hollow mandrel, so that it is firmly held there. Since the outside diameter of the hollow mandrel should also correspond to the inside diameter of the tube neck according to the invention, the membrane is cut so cleanly that on the one hand the full inside diameter of the tube outlet opening is available for expressing the mass filled in the tube and on the other hand no pushed or torn off Membrane parts can leak more with the mass. This not only solves the task, according to which the membrane should no longer be pressed into the interior of the tube, but also ensures that the mass filled into the tube can be squeezed out over the full open cross-section of the tube outlet opening and also that on the tube neck due to membrane portions protruding into the tube neck. no "dead corners", behind which hardening contents of the tube could stick.

.Gerade um solche Vorsprünge beziehungsweise "toten Ecken" zu vermeiden, empfiehlt es sich, daß die Schneidkante beziehungsweise die Dornzackenkanten ins Innere des Hohldorns hinein abgeschrägt sind, daß also die Außenfläche des. Hohldorns bis zur Schneidkante hin zylindrisch verläuft.Especially to avoid such projections or "dead corners", it is recommended that the cutting edge or the spike edges are bevelled into the interior of the hollow mandrel, so that the outer surface of the hollow mandrel is cylindrical to the cutting edge.

Um ein leichtes Abscheren der Membrane zu erreichen, kann die Schneidkante auch schraubengangförmig verlaufen, wodurch nach und nach, gleichzeitig mit dem Aufschrauben der Verschlußkappe, die Membrane eingeschnitten beziehungsweise abgetrennt wird.To achieve easy shearing of the membrane, the cutting edge can also be screw-shaped run, whereby little by little, at the same time as the cap is screwed on, the membrane is cut or separated.

Um mit Sicherheit das losgetrennte Membranplättchen festzuhalten, kann im Inneren des Hohldorns mit Abstand von der Schneidkante eine ringförmige Vertiefung oder eine Ringwulst vorgesehen sein, es kann ein Gewinde im Inneren des Hohldorns vorgesehen oder es kann auch die Innenseite des Hohldorns aufgerauht oder quer geriffelt sein.In order to securely hold the separated membrane plate, an annular recess or an annular bead can be provided in the interior of the hollow mandrel at a distance from the cutting edge, a thread can be provided in the interior of the hollow mandrel or the inside of the hollow mandrel can also be roughened or corrugated transversely.

Insbesondere für verhältnismäßig dicke Membranen empfiehlt es sich, daß senkrecht im Hohldorn ein Führungsdorn angeordnet ist, der auch bei geringer Elastizität der Membrane für ein sicheres Anpressen des Materials im Hohldorn und damit für den sicheren Halt des losgetrennten Membranplättchens sorgt. Wird der Führungsdorn einem weiteren Erfindungsmerkmal nach über die Zacken hinausgeführt, und ist er außerdem aufgerauht oder quer geriffelt, oder weist er, mit Abstand von seiner Spitze, vorzugsweise der Ringwulst oder der ringförmigen Vertiefung im Hohldorn gegenüberliegend eine ringförmige Aussparung auf, so wird sich auch das losgetrennte Membranplättchen bereits auf diesem Führungsdorn so festklemmen, daß es keinesfalls mehr in das Innere der Tube gelangen kann. Eine besonders zweckmäßige Ausführung sieht ein Gewinde auf dem Führungsdorn vor, wobei dieses Gewinde steigungsgleich oder auch mit höherer Steigung ausgeführt werden kann als das Verschlußkappen-Aufschraubgewinde. Der Führungsdorn schraubt sich bei dieser Ausführungsform in die Membrane ein, die, wird sie anschließend von dem Hohldorn losgeschnitten, sicher auf dem Gewinde dieses Führungsdorns gehalten ist.In particular for relatively thick membranes, it is recommended that a guide mandrel be arranged vertically in the hollow mandrel, which ensures that the material in the hollow mandrel is securely pressed on, even with low elasticity of the membrane, and thus that the detached membrane plate is held securely. If, according to another feature of the invention, the guide mandrel extends beyond the prongs, and if it is also roughened or grooved transversely, or if it preferably has an annular recess opposite it at a distance from its tip, the annular bead or the annular recess in the hollow mandrel, this will also result Clamp the separated membrane plate on this guide mandrel so that it can no longer get inside the tube. A particularly expedient embodiment provides for a thread on the guide mandrel, this thread being able to be made with the same pitch or with a higher pitch than the screw-on screw cap. In this embodiment, the guide mandrel screws into the membrane, which, when it is subsequently cut free from the hollow mandrel, is held securely on the thread of this guide mandrel.

Eine weitere Möglichkeit besteht darin, daß die Membrane einen senkrecht nach außen stehenden Zapfen aufweist, dessen Außendurchmesser mit der lichten Weite des Hohldorns übereinstimmt. Bei dieser erfindungsgemäßen Ausführung der Tube wird bei deren erstmaligem Öffnen erst der Hohldorn über den Zapfen übergeführt, beim Weiterführen der Verschlußkappe sodann die Membrane abgeschert und die Membrane damit wiederum.sicher in der Verschlußkappe gehalten. Hierzu kann beitragen, daß der Zapfen hohl ist, sich also elastisch nachgebend an die Innenwandung des Hohldorns anlegen kann. Selbstverständlich kann hier auch wiederum der Zapfen aufgerauht, quer geriffelt oder mit einer ringförmigen Vertiefung beziehungsweise einer Ringwulst versehen sein, oder es kann auch auf der Zapfenaußenfläche und/oder der Hohldorninnenfläche ein,-gegebenenfalls dem Schraubverschlußgewinde entsprechendes Gewinde vorgesehen sein.Another possibility is that the membrane has a pin which is perpendicular to the outside and the outside diameter of which corresponds to the inside diameter of the hollow mandrel. In this embodiment of the tube according to the invention, the hollow mandrel is first transferred over the pin when it is opened for the first time, then the membrane is sheared off when the closure cap is continued and the membrane is in turn securely held in the closure cap. This can be helped by the fact that the peg is hollow, that is to say it resiliently rests against the inner wall of the hollow mandrel. Of course, the pin can also be roughened, grooved transversely or provided with an annular recess or an annular bead, or it can also be provided on the outer surface of the pin and / or the hollow mandrel inner surface, if appropriate a thread corresponding to the screw closure thread.

Als ganz besonderer Vorteil ist noch hervorzuheben, daß der Hohldorn nicht nur die Membrane sauber abschert und sicher hält, sondern daß sich, durch das Einfügen des Hohldorns, wenn er im Innern der Verschlußkappe angeordnet.ist, ein außerordentliche dichter Verschluß, zusätzlich zu der Abdichtung, die durch das Aufliegen der Verschlußkappe auf der Stirnkante des Tubenhalses gegeben ist, ergibt. Da hierzu eine möglichst genaue Passung zwischen der Außenseite des Hohldorns und dem lichten Durchmesser des Tubenhalses erwünscht ist und dadurch das Einführen des Hohldorns erschwert werden könnte, empfiehlt es sich, daß der Tubenhalsmund trichterförmig ausgeführt wird.As a very special advantage, it should be emphasized that the hollow mandrel not only shears off the membrane cleanly and holds it securely, but that by inserting the hollow mandrel, when it is arranged inside the sealing cap, an extraordinarily tight closure, in addition to the seal , which is given by the resting of the closure cap on the front edge of the tube neck. Since the best possible fit between the outside of the hollow mandrel and the inside diameter of the tube neck is desired and the insertion of the hollow mandrel could thereby be made more difficult, it is recommended that the tube neck mouth be made funnel-shaped.

Zum leichteren Abscheren der Membrane kann diese auch mit einer, bei der Tubenhalswandung angeordneten kreisförmigen Einkerbung versehen sein.To facilitate shearing of the membrane, it can also be provided with a circular indentation arranged at the tube neck wall.

Exemplary embodiments of the subject matter of the invention are shown schematically in the drawing, namely:
  • Fig. 1 shows a first embodiment of a tube longitudinal section with the cap and
  • 2 in the same representation, a screwed cap,
  • Fig. 3, the top of a cap with hollow mandrel!
  • 4 an embodiment with a guide mandrel with thread,
  • Fig. 5 in the same representation as Fig. 1, a membrane with pin and
  • Fig. 6 this version with screwed cap.

Eine Tube 1 ist mündungsseitig mit einem Kunststoffgewinde 2 versehen, auf das eine Verschlußkappe 6 aufgeschraubt werden kann. Der Tubenhals der Tube 1 ist durch eine Membrane 3 verschlossen, die randständig mit einer Einkerbung 5 versehen ist.A tube 1 is provided on the mouth side with a plastic thread 2 onto which a closure cap 6 can be screwed. The tube neck of the tube 1 is closed by a membrane 3, which is provided with a notch 5 at the edges.

Im Inneren der Verschlußkappe 1 ist ein Hohldorn 7 angeordnet, dessen ringförmige Stirnkante als zackenförmige Schneidkante 8 ausgebildet ist. Zentrisch im Inneren dieses Hohldorns 7 ist ein Führungsdorn 9 angeordnet, dessen Spitze über die Schneidkante 8 hinausragt.A hollow mandrel 7 is arranged in the interior of the closure cap 1, the annular end edge of which is designed as a serrated cutting edge 8. A guide mandrel 9 is arranged centrally in the interior of this hollow mandrel 7, the tip of which projects beyond the cutting edge 8.

Fig. 2 zeigt den Zustand nach dem Aufschrauben der Verschlußkappe 6 auf das-Kunststoffgewinde 2. Bei diesem Aufschrauben durchbohrt zuerst der Führungsdorn 9 die Membrane 3, wodurch sich, das Membranmaterial 3 bereits elastisch an den Führungsdorn 9 anklammert. Im weiteren Verlauf der Eindrehbewegung trennt die Schneidkante 8 die Membrane 3 vom Tubenhals 10 ab, so daß sie etwa in die Lage wie in Fig. 2 dargestellt gedrückt wird.FIG. 2 shows the state after the closure cap 6 has been screwed onto the plastic thread 2. During this screwing, the guide mandrel 9 first pierces the membrane 3, as a result of which the membrane material 3 already clings elastically to the guide mandrel 9. The cutting separates as the screwing movement continues edge 8 of the membrane 3 from the tube neck 10, so that it is pressed approximately into the position as shown in Fig. 2.

Deutlicher ist dies nochmals in Fig. 3 gezeigt, wo auch dargestellt ist, wie der Hohldorn in den Kopf der Verschlußkappe 7 eingesetzt werden kann. In Fig. 3 ist sowohl der Führungsdorn 9, wie auch der Hohldorn 7 quer geriffelt 11, um einen sicheren Halt des abgescherten Membranplättchens 3 zu erreichen.This is shown more clearly in FIG. 3, where it is also shown how the hollow mandrel can be inserted into the head of the closure cap 7. In Fig. 3, both the guide mandrel 9 and the hollow mandrel 7 are corrugated 11 to achieve a secure hold of the sheared membrane plate 3.

Fig. 4 zeigt eine Ausführung mit einem Führungsdorn 9, der mit einem Gewinde 12 versehen ist. Beim Aufschrauben dieser Verschlußkappe 6 trifft zuerst der spitze FÜhrungsdorn 9 auf die Membrane 3 auf, durchbohrt sie und schraubt sich in das Material der Membrane 3 ein. Erst danach trifft die Schneidkante 8 des Hohldorns 7 auf das Membranmaterial und schneidet das Membranplättchen von der Tubenhalswandung ab. Dieses Membranplättchen 3 wird nun jedoch sicher auf dem Gewinde 12 des Führungsdorns 9 gehalten, abgesehen davon, daß es ja auch noch in das Innere des Hohldorns 7 eingepreßt ist.Fig. 4 shows an embodiment with a guide mandrel 9, which is provided with a thread 12. When this cap 6 is screwed on, the pointed guide pin 9 first hits the membrane 3, drills it and screws into the material of the membrane 3. Only then does the cutting edge 8 of the hollow mandrel 7 hit the membrane material and cut the membrane plate from the tube neck wall. However, this membrane plate 3 is now securely held on the thread 12 of the guide mandrel 9, apart from the fact that it is also pressed into the interior of the hollow mandrel 7.

In den Fig. 5 und 6 ist schließlich eine Ausführung gezeigt, bei der auf der Membrane 3 ein Zapfen 4 angebracht ist. Über diesen Zapfen 4 schiebt sich beim Aufschrauben der Verschlußkappe 6 auf das Kunststoffgewinde 2 der Hohldorn 7, der im weiteren Verlauf der Aufdrehbewegung die Membrane 3 abschert. Dieser Zustand ist in Fig. 6 gezeigt, woraus auch ersichtlich ist, daß diese abgescherte Membrane.nun sicher in der Verschlußkappe 6 gehalten ist.5 and 6, finally, an embodiment is shown in which a pin 4 is attached to the membrane 3. About this pin 4 pushes the cap 6 on the plastic thread 2 of the hollow mandrel 7, which shears the membrane 3 in the further course of the unscrewing. This state is shown in Fig. 6, from which it can also be seen that this sheared Membrane.nun is now securely held in the cap 6.
