Description

B E S C H R E I B U N G  DESCRIPTION
Verschluss mit einem Dorn für einen Behälter Lock with a spike for a container
Die Erfindung betrifft einen Verschluss mit einem Dorn für einen Behälter, einen Dorn sowie ein Verfahren zur Herstellung eines solchen Domes gemäß den Merkmalen der Oberbegriffe der jeweiligen unabhängigen Patentansprüche. The invention relates to a closure with a mandrel for a container, a mandrel and a method for producing such a mandrel according to the features of the preambles of the respective independent claims.
Aus der EP 1 737 743 B1 ist ein Behälterverschluss für einen Behälter mit einem sogenannten Push-Pull-Verschluss bekannt, wobei der Behälter Verschluss (dort Bezugsziffer 2) im Hüllenteil (dort Bezugsziffer 1) einen verschieblichen Dorn (dort Bezugsziffer 9) mit einer Aufreiß- und Durchstoßeinrichtung (dort Bezugsziffer 10) aufweist. From EP 1 737 743 B1 a container closure for a container with a so-called push-pull closure is known, wherein the container closure (there reference numeral 2) in the shell part (there reference numeral 1) a displaceable mandrel (there reference numeral 9) with a tear - And puncture device (there reference numeral 10).
Dieser verschieblich gelagerte Dorn muss gegen seiner äußeren Umgebung (bei der EP 1 737 74 B1) z. B. gegenüber dem Zusatzraum (dort Bezugsziffer 8) oder einem Raum, der von einer Sicherheitskappe (dort Bezugsziffer 15) gebildet wird, abgedichtet werden. This displaceably mounted mandrel must against its external environment (in EP 1 737 74 B1) z. B. against the additional space (there reference numeral 8) or a space which is formed by a safety cap (there reference numeral 15) are sealed.
Aus diesem Stand der Technik sind keine Dichtungsmaßnahmen bekannt. From this state of the art no sealing measures are known.
Der Erfindung liegt daher die Aufgabe zugrunde, einen Verschluss mit einem Dorn für einen Behälter bzw. einen Dorn selber bereitzustellen, mit dem Dichtungsmaßnahmen realisiert sind. Außerdem soll ein Herstellungsverfahren für einen solchen Dorn für einen Verschluss für einen Behälter angegeben werden, der zu Dichtzwecken ausgebildet ist. Erfindungsgemäß ist hierzu vorgesehen, dass der Dorn (auch Stechnagel genannt) in seinem axialen Verlauf betrachtet zumindest eine umlaufende Dichtung, vorzugsweise zwei in einem definierten Abstand zueinander angeordnete umlaufende Dichtungen aufweist. The invention is therefore based on the object to provide a closure with a mandrel for a container or a mandrel itself, are realized with the sealing measures. In addition, a manufacturing method for such a mandrel for a closure for a container is specified, which is designed for sealing purposes. According to the invention, it is provided for this purpose that the mandrel (also called a piercing nail) has at least one circumferential seal, preferably two circumferential seals arranged at a defined distance from one another, in its axial profile.
Die zumindest eine Dichtung, vorzugsweise die zumindest zwei Dichtungen, stützen sich an dem Gehäuse des Verschlusses für den Behälter ab. Dadurch wird es möglich, dass der Dorn verschiebbar in dem Gehäuse angeordnet ist und den Raum, in dem ein Material eingefüllt ist, in seiner ersten Position gegenüber der äußeren Umgebung abdichtet. Wird der Dorn durch manuelle Einwirkung verschoben, werden auch die zumindest eine Dichtung, vorzugsweise die beiden Dichtungen, so verschoben, dass die bis dahin von der Dichtung und dem Dorn verschlossene Öffnung in dem Gehäuse freigegeben wird. Dadurch kann beispielsweise eine Flüssigkeit, die vorher mit dem Material gemischt wurde, über den Verschluss des Behälters aus dem Behälter (zum Beispiel durch Trinken) entnommen werden. The at least one seal, preferably the at least two seals, are supported on the housing of the closure for the container. This makes it possible for the mandrel to be displaceably arranged in the housing and seals the space in which a material is filled in its first position relative to the external environment. If the mandrel is displaced by manual action, the at least one seal, preferably the two seals, are also displaced in such a way that the opening, which has hitherto been sealed by the seal and the mandrel, is released in the housing. As a result, for example, a liquid previously mixed with the material may be withdrawn via the closure of the container from the container (for example by drinking).
Weiterhin sind zwei alternative Verfahren zur Herstellung eines solchen Domes für einen Behälterverschluss angegeben. Furthermore, two alternative methods for producing such a dome for a container closure are given.
Zum einen ist erfind ungsgemäß vorgesehen, dass zunächst der Dorn selber in einem Spritzgussverfahren aus dem geeigneten Kunststoffmaterial hergestellt und separat davon zumindest eine Dichtung, vorzugsweise beide Dichtungen, hergestellt und danach auf dem Dorn festgelegt wird. On the one hand, it is provided according to the invention that firstly the mandrel itself is produced in an injection molding process from the suitable plastic material and separately at least one seal, preferably both seals, is produced and then fixed on the mandrel.
Alternativ dazu ist es denkbar, dass zunächst wiederum der Dorn in einem Spritzgussverfahren aus einem geeigneten Kunststoffmaterial in einem Spritzgusswerkzeug hergestellt und danach in dem gleichen Spritzgusswerkzeug die zumindest eine Dichtung, vorzugsweise beide Dichtungen, aus einem anderen Material als das, aus dem der Dorn besteht, ebenfalls in einem Spitzgussverfahren hergestellt wird. Die beiden Varianten zur Ausgestaltung eines Domes für einen Behälterverschiuss, die auf unterschiedliche Art und Weise hergestellt worden sind, sind in den beiden Figuren 1 und 2 gezeigt und im Folgenden erläutert. Alternatively, it is conceivable for the mandrel in turn to be produced in an injection molding process from a suitable plastic material in an injection molding tool and then in the same injection molding tool the at least one seal, preferably both seals, of a different material than that from which the mandrel is made, also produced in an injection molding process. The two variants for the design of a dome for a Behälterverschiuss, which have been produced in different ways, are shown in the two figures 1 and 2 and explained below.
Figur 1 zeigt, soweit im Einzelnen dargestellt, einen Dorn für einen Behälterverschiuss. Der Verschluss für einen Behälter weist einen Raum auf, in den ein Material eingefüllt ist, wobei der Dorn 1 verschiebbar in dem Gehäuse angeordnet ist und eine Abdeckung einer Öffnung in dem Gehäuse durchstoßen kann, damit das Material von dem Raum in dem Gehäuse in den Behälter gelangen kann. Rein beispielhaft für einen solchen Verschluss sei auf die die EP 1 737 743 B1 verwiesen. Die Anwendung des hier beschriebenen erfindungsgemäßen Verschlusses sowie des Domes sowie der Herstellungsverfahren eines solchen Domes sind jedoch in keinster Weise auf diesen Stand der Technik eingeschränkt, sodass der Dorn auch für vergleichbare Ausgestaltungen eines solchen Verschlusses für einen Behälter angewendet werden kann. FIG. 1 shows, as far as shown in detail, a mandrel for a container closure. The closure for a container has a space in which a material is filled, wherein the mandrel 1 is slidably disposed in the housing and can pierce a cover of an opening in the housing, so that the material from the space in the housing into the container can get. Purely as an example of such a closure, reference is made to EP 1 737 743 B1. However, the application of the inventive closure and the dome as well as the manufacturing method of such a dome described herein are in no way limited to this prior art, so that the mandrel can also be used for comparable embodiments of such a closure for a container.
Der Dorn 1 , der in Figur 1 dargestellt ist, ist in seinem oberen Endbereich tellerförmig ausgestaltet, wobei der untere Endbereich bei der Darstellung der Figur 1 abgeschnitten und nicht näher dargestellt oder erläutert ist. Der untere Bereich ist auf jeden Fall in einer solchen Art und Weise ausgestaltet, dass er dazu geeignet ist, die Abdeckung der Öffnung in dem Gehäuse zu durchstoßen. Zwischen dem oberen und unteren Endbereich des Domes 1 befindet sich in seinem axialen Verlauf zumindest eine Dichtung 2, wobei bei dem Ausführungsbeispiel gemäß Figur 1 zwei Dichtungen 2, 3, die voneinander beanstandend sind, angeordnet sind. Die beiden Dichtungen 2, 3 können gleiche Geometrien aufweisen und/oder aus gleichem Material bestehen. Bei dem Ausführungsbeispiel gemäß Figur 1 ist die Dichtung 2 durchmesserkleiner als die Dichtung 3, wobei auch die umgekehrte Variante denkbar ist. Wichtig ist, dass die zumindest eine Dichtung 2, insbesondere die beiden Dichtungen 2, 3, so gestaltet sind, dass sie sich den Anlagegeometrien des Domes 1 anpassen und nicht nur gegenüber dem Dorn 1 , wo sie anliegen, sondern auch gegenüber dem Gehäuse des Verschlusses des Behälters anliegen und so die gewünschte Dichtwirkung in der einen Position des Domes 1 in Bezug auf das Gehäuse des Verschlusses bewirken. In dem Ausführungsbeispiel gemäß Figur 1 ist zunächst der Dorn 1 in einem Spritzgussverfahren in einem entsprechend formgebenden Spritzgusswerkzeug hergestellt worden. In dem gleichen Spritzgusswerkzeug wurde dann ebenfalls formgebend die zumindest zweite Dichtung 2, vorzugsweise die beiden Dichtungen 2, 3 ebenfalls in einem Spritzgussverfahren hergestellt. Hierbei handelt es sich um ein Zwei-Komponenten-Werkzeug bzw. um ein Zwei-Komponenten- Spritzgussverfahren. Die Wahl des Materiales für den Dorn 1 einerseits und die zumindest eine Dichtung 2, bzw. die beiden Dichtungen 2, 3 andererseits, richtet sich nach dem Einsatzzweck. Insbesondere besteht der Dorn 1 aus einem harten Kunststoffmaterial, um die auf ihn wirkenden Druckkräfte für die axiale Verschiebung aushalten zu können. Das Material für die zumindest eine Dichtung 2 richtet sich dabei nach der Dichtfunktion. The mandrel 1, which is shown in Figure 1, is designed plate-shaped in its upper end portion, wherein the lower end portion in the illustration of Figure 1 is cut off and not shown or explained in detail. The lower portion is in any case designed in such a way that it is suitable for piercing the cover of the opening in the housing. Between the upper and lower end region of the dome 1 there is at least one seal 2 in its axial course, wherein in the exemplary embodiment according to FIG. 1 two seals 2, 3 which are objectionable to each other are arranged. The two seals 2, 3 may have the same geometries and / or consist of the same material. In the embodiment according to Figure 1, the seal 2 is smaller in diameter than the seal 3, wherein the reverse variant is conceivable. It is important that the at least one seal 2, in particular the two seals 2, 3, are designed so that they adapt to the investment geometries of the dome 1 and not only against the mandrel 1, where they rest, but also with respect to the housing of the closure abut the container and thus effect the desired sealing effect in the one position of the dome 1 with respect to the housing of the closure. In the embodiment according to FIG. 1, first of all the mandrel 1 has been produced in an injection molding process in a correspondingly shaping injection molding tool. In the same injection molding tool, the at least second seal 2, preferably the two seals 2, 3 was then likewise likewise produced in an injection molding process. This is a two-component mold or a two-component injection molding process. The choice of the material for the mandrel 1 on the one hand and the at least one seal 2, or the two seals 2, 3 on the other hand, depends on the purpose. In particular, the mandrel 1 is made of a hard plastic material in order to be able to withstand the compressive forces acting on it for the axial displacement. The material for the at least one seal 2 depends on the sealing function.
Figur 2 zeigt an sich den gleichen Aufbau des Domes 1 wie in Figur 1 , jedoch mit dem Unterschied, dass der Dorn 1 separat zu der zumindest einen Dichtung 2, insbesondere den beiden Dichtungen 2, 3, hergestellt wird. Liegen die voneinander hergestellten Teile separat voneinander vor, können diese anschließend montiert werden. Dabei sind aligemein die Anlagegeometrien der zumindest einen Dichtung 2 der Anlagegeometrie des Dornes 1 angepasst. Beispielhaft sei hier erwähnt, dass eine der beiden Dichtungen 2, 3 (oder auch beide Dichtungen 2, 3) als O-Ring ausgebildet ist (aufweisend einen runden Querschnitt) und die Anlagegeometrie in dem Dorn 1 eine umlaufende Nut mit einem in etwa halbkreisförmigen Querschnitt ausgebildet ist. Diese Anlagegeometrien sind nur beispielhaft und können selbstverständlich auch anders gestaltet sein. Figure 2 shows in itself the same structure of the dome 1 as in Figure 1, but with the difference that the mandrel 1 is made separately from the at least one seal 2, in particular the two seals 2, 3. If the parts produced from each other are separate, they can then be mounted. In this case, the system geometries of the at least one seal 2 of the system geometry of the mandrel 1 are generally adapted. By way of example, it should be mentioned here that one of the two seals 2, 3 (or both seals 2, 3) is formed as an O-ring (having a round cross-section) and the investment geometry in the mandrel 1 is a circumferential groove with an approximately semicircular cross section is trained. These investment geometries are only examples and can of course be designed differently.
Diese Dichtungen können beispielsweise als separate Bauteile ausgebildet sein und nach der Herstellung des ein- oder zweiteiligen Dornes montiert werden. Solche separaten Bauteile sind z. B. O-Ringe oder dergleichen. Hierzu weist der Dorn beispielsweise eine umlaufende Nut ein, in die das Dichtelement formschlüssig eingepasst wird. Die radial umlaufende Dichtung kann aber auch in einem Spritzgussverfahren hergestellt werden. In diesem Fall ist es denkbar, dass die radial umlaufende Dichtung im gleichen Werkzeug in einem zwei-komponentenverfahren zusammen mit der Herstellung des Domes realisiert, insbesondere gespritzt wird. Da aufgrund der Funktionen an den Dorn und das Dichtungseiement unterschiedlicher Anforderungen gestellt werden, bestehen diese vorzugsweise aus unterschiedlichen Materialien, insbesondere Kunststoffmaterialien. Der Dorn selber besteht aus einem harten Kunststoffmaterial, welches gewährleistet, dass die auf ihn wirkenden Kräfte (Durchstoßkräfte) übertragen werden können. Da das Dichtelement eine Dichtungsfunktion übernehmen muss, besteht es aus einem elastisch verformbaren Kunststoffmaterial. These seals may for example be formed as separate components and be mounted after the production of one or two-piece mandrel. Such separate components are z. B. O-rings or the like. For this purpose, the mandrel, for example, a circumferential groove, into which the sealing element is fitted positively. The radially circumferential seal can also be produced in an injection molding process. In this case, it is conceivable that the radially encircling seal is realized in the same tool in a two-component method together with the production of the dome, in particular injection molding. Since due to the functions of the mandrel and the Dichtungsseiement different requirements are made, these are preferably made of different materials, especially plastic materials. The mandrel itself consists of a hard plastic material, which ensures that the forces acting on it (puncture forces) can be transmitted. Since the sealing element must assume a sealing function, it consists of an elastically deformable plastic material.
Während es einerseits denkbar ist, dass der Dorn und das zumindest eine Dichtelement, vorzugsweise die beiden Dichtelemente, im gleichen Spritzgusswerkzeug hergestellt werden, ist es auch denkbar, dass zuerst der Dorn in einem ersten Spritzgusswerkzeug hergestellt wird und anschließend in einem weiteren Werkzeug der schon hergestellte Dorn eingelegt wird und anschließend mit dem vorzugsweisen elastisch verformbaren Kunststoffmaterial umspritzt wird. While it is conceivable on the one hand that the mandrel and the at least one sealing element, preferably the two sealing elements are produced in the same injection mold, it is also conceivable that first the mandrel is produced in a first injection molding tool and then in another tool of the already produced Mandrel is inserted and then encapsulated with the preferred elastically deformable plastic material.
Im Regelfall ist, wie in dem genannten Stand der Technik, der Dorn zweiteilig ausgebildet, wobei zumindest eines der beiden Teile des Domes das eine Dächtelement aufweist. Weiterhin ist es denkbar, dass an einem Teil des zweiteiligen Domes zwei Dichtelemente und dann im zweiten Teil kein Dichtelement vorhanden ist, wobei es ebenfalls denkbar ist, wobei es ebenfalls denkbar ist, dass jedes Teil des Domes ein eigenes Dichteiement aufweist. Alternativ dazu kann der Dorn einteilig ausgestaltet sein und das zumindest eine Dichtelement aufweisen. As a rule, as in the mentioned prior art, the mandrel is formed in two parts, wherein at least one of the two parts of the dome has the one guard element. Furthermore, it is conceivable that on one part of the two-part dome two sealing elements and then in the second part no sealing element is present, wherein it is also conceivable, wherein it is also conceivable that each part of the dome has its own density element. Alternatively, the mandrel may be configured in one piece and have at least one sealing element.
