Description

Die Erfindung bezieht sich auf eine Vorrichtung gemäß dem Oberbegriff des Anspruchs 1.The invention relates to a device according to the preamble of claim 1.

Vorrichtungen zum Mischen zweier Komponenten, bestehend aus einem Gefäß mit einem Schraubgewinde und einem auf das Gefäß aufschraubbaren Schraubelement sind in den verschiedensten Ausführungsformen bekannt. Es gibt zum Beispiel Aufsätze, die über eine Schraubbewegung eines Schraubelementes auf einem Gewindehals eines Gefäßes in der Lage sind, in das Gefäß eingesetzte Folien durchzutrennen.Devices for mixing two components, consisting of a vessel with a screw thread and a screw element that can be screwed onto the vessel, are known in a wide variety of embodiments. There are, for example, attachments which are able to cut films inserted into the vessel by screwing a screw element on a threaded neck of a vessel.

Bei einer aus der DE-C-39 24 152 bekannten Vorrichtung ist ein Schraubelement in Form einer Kappe mit einem in den Gewindehals eines Behälters hineinragenden Zahn versehen, der bei einer Schraubbewegung der Kappe eine Folie im Gewindehals herausschneidet. Trennt die Folie zwei verschiedene Komponenten, zum Beispiel zwei Flüssigkeiten oder eine Flüssigkeit und einen pulverförmigen Stoff, so ergibt sich nach der Durchtrennung der Folie und dem Schütteln des Behälters eine Mischung der beiden Komponenten.In a device known from DE-C-39 24 152, a screw element in the form of a cap is provided with a tooth protruding into the threaded neck of a container, which tooth cuts out a film in the threaded neck when the cap is screwed. If the film separates two different components, for example two liquids or a liquid and a powdery substance, a mixture of the two components results after the film has been cut through and the container shaken.

Sinnvoll ist die Verwendung derartiger Vorrichtungen zum Beispiel zur getrennten Aufbewahrung von Flüssigkeitskomponenten, die erst kurz vor ihrem Gebrauch vermischt werden sollen. Eine Mischung aus den Einzelkomponenten ist dann nur über eine gewisse Zeitdauer verarbeitbar, so zum Beispiel die Komponenten Dauerwellösung und Ester für eine Haarbehandlung. Derartige Vorrichtungen können sinnvoll auch zur getrennten Aufbewahrung eines staubenden Produktes und einer Flüssigkeit verwendet werden. Infolge der Auflösung des staubenden Produktes, zum Beispiel eines natürlichen Haarfärbepulvers, in der Flüssigkeit ist eine Staubentwicklung zu Lasten eines Anwenders zu keiner Zeit gegeben.It makes sense to use such devices, for example for the separate storage of liquid components which are to be mixed only shortly before they are used. A mixture of the individual components can then only be processed over a certain period of time, for example the components permanent wave solution and ester for one Hair treatment. Such devices can also be used for the separate storage of a dusting product and a liquid. As a result of the dissolution of the dusting product, for example a natural hair dye powder, in the liquid there is no dust development at the expense of a user at any time.

Nachteilig bei den bekannten Vorrichtungen ist, daß sie für eine zumindest teilweise Wiederbenutzung nicht geeignet sind. Sie sind relativ aufwendig konstruiert und damit teuer in der Herstellung. Nach der Zerstörung einer die Komponenten trennenden Folie ist eine Wiederherstellung der Funktionstüchtigkeit der Vorrichtung durch einen Anwender nicht möglich.A disadvantage of the known devices is that they are not suitable for at least partial reuse. They are relatively complex and therefore expensive to manufacture. After a film separating the components has been destroyed, it is not possible for a user to restore the functionality of the device.

Der Erfindung liegt die Aufgabe zugrunde, eine Vorrichtung zum Mischen zweier Komponenten zu schaffen, die oben genannte Nachteile nicht aufweist, und bei der die Wiederherstellung der Funktionstüchtigkeit der Vorrichtung durch einen Anwender problemlos möglich ist.The invention has for its object to provide a device for mixing two components, which does not have the disadvantages mentioned above, and in which the functionality of the device can be easily restored by a user.

Gelöst ist die Aufgabe gemäß dem kennzeichnenden Teil des Anspruchs 1. Nach Anspruch 1 ist am oberen Rand eines offenen Gefäßes mindestens ein Schneiddorn vorgesehen, in ein auf das Gefäß aufschraubbares Schraubelement ist ein lösbares Depotgefäß mit einer gefäßseitig aufschneidbaren Folie eingesetzt, und der untere Innendurchmesser des Depotgefäßes ist größer als der doppelte Abstand zwischen der Mittelachse des Gefäßes und dem Schneiddorn, so daß während des Festdrehens des Schraubelementes auf dem Schraubgewinde des Gefäßes die Folie vom Schneiddorn durchstochen und kreisförmig aufgeschnitten wird.The object is achieved according to the characterizing part of claim 1. According to claim 1, at least one cutting mandrel is provided at the top of an open vessel, a detachable depot vessel with a foil that can be cut on the vessel side is inserted into a screw element that can be screwed onto the vessel, and the lower inside diameter of the Depot vessel is greater than twice the distance between the central axis of the vessel and the cutting mandrel, so that the film is pierced by the cutting mandrel during the tightening of the screw element on the screw thread of the vessel and is cut open in a circle.

Bei der Lösung nach Anspruch 1 wird das Depotgefäß in das Schraubelement gesetzt und anschließend das Schraubelement auf dem Gefäß festgeschraubt.
Beim Aufsetzen des Schraubelementes auf das Gefäß durchsticht der auf dem oberen Rand des Gefäßes angeordnete Schneiddorn die Folie des Depotgefäßes. Während des Festdrehens des Schraubelementes auf dem Schraubgewinde des Gefäßes wird die Folie kreisförmig aufgeschnitten. Dadurch gelangt eine im Depotgefäß enthaltene Produktkomponente in das darunterliegende Gefäß zu einer dort vorhandenen zweiten Produktkomponente. Die gesamte Vorrichtung zum Mischen der Produktkomponenten ist hermetisch abgeschlossen. Die Durchmischung der beiden Produktkomponenten kann durch Schütteln der Vorrichtung verbessert werden.In the solution according to claim 1, the depot vessel is placed in the screw element and then the screw element is screwed onto the vessel.
When the screw element is placed on the vessel, the cutting mandrel arranged on the upper edge of the vessel pierces the film of the depot vessel. While the screw element is tightened on the screw thread of the vessel, the film is cut open in a circle. As a result, a product component contained in the depot vessel reaches the underlying vessel to a second product component present there. The entire device for mixing the product components is hermetically sealed. The mixing of the two product components can be improved by shaking the device.

Die erfindungsgemäße Vorrichtung ist relativ einfach konstruiert und daher kostengünstig herstellbar. Das Gefäß und das Schraubelement können im Spritzgießverfahren, das Depotgefäß kann im Tiefziehverfahren hergestellt werden. Die Folie für das Depotgefäß wird zum Beispiel durch Heißsiegelung mit dem Depotgefäß verbunden. Das Gefäß und das Schraubelement können nach ihrer Reinigung mittels eines neuen Depotgefäßes wiederverwendet werden. Die Wiederherstellung der Funktionstüchtigkeit der Vorrichtung ist durch einen Anwender insofern problemlos möglich, als anstatt eines geleerten Depotgefäßes lediglich ein neues, gefülltes Depotgefäß in das Schraubelement gesteckt werden muß.The device according to the invention is relatively simple in construction and therefore inexpensive to manufacture. The vessel and the screw element can be manufactured using the injection molding process, the depot vessel can be manufactured using the deep-drawing process. The film for the depot vessel is connected to the depot vessel, for example, by heat sealing. The vessel and the screw element can be reused after cleaning with a new depot vessel. A restoration of the functionality of the device is easily possible by a user insofar as, instead of an empty depot vessel, only a new, filled depot vessel has to be inserted into the screw element.

Weitere vorteilhafte Ausgestaltungen der erfindungsgemäßen Vorrichtung sind in den Ansprüchen 2 bis 9 beschrieben.Further advantageous configurations of the device according to the invention are described in claims 2 to 9.

Ist ein Gewindeanschlag am Gefäß für einen Schneidweg des Schneiddorns durch die Folie von etwas mehr als einem Dreiviertelkreis vorgesehen (Anspruch 2), dann wird verhindert, daß die Folie vollständig vom Depotgefäß abgetrennt wird und in das darunterliegende Gefäß fällt, wo sich die beiden Produktkomponenten vermischen.If a thread stop on the vessel for a cutting path of the cutting mandrel through the film is provided by a little more than a three-quarter circle (claim 2), then it is prevented that the film is completely separated from the depot vessel and falls into the vessel below, where the two product components mix .

Sind am Schraubelement Mitnahmenocken und am Depotgefäß Mitnahmeaussparungen vorgesehen (Anspruch 3), oder umgekehrt (Anspruch 4), so wird erreicht, daß sich beim Festschrauben des Schraubelementes in gleicher Weise das Depotgefäß mitdreht, so daß der Schneiddorn die Folie durchschneidet. Schlupf zwischen dem Schraubelement und dem Depotgefäß wird somit vermieden.If driving cams are provided on the screwing element and driving recesses are provided on the depot vessel (claim 3), or vice versa (claim 4), it is achieved that the depot vessel rotates in the same way when the screwing element is screwed on, so that the cutting mandrel cuts through the film. Slip between the screw element and the depot vessel is thus avoided.

Ist die Folie eine kunststoffbeschichtete Aluminiumfolie (Anspruch 5), so werden die beiden Komponenten von einer Folie getrennt, die auf Grund der Aluminiumschicht sehr gute Barriereeigenschaften bezüglich einer Produktdiffussion aufweist, und die auf Grund ihrer Kunststoffbeschichtung (zum Beispiel gleicher Kunststoff wie das Depotgefäß) auf den Rand des Depotgefäßes gesiegelt werden kann.If the film is a plastic-coated aluminum film (claim 5), the two components are separated from a film which has very good barrier properties with regard to product diffusion due to the aluminum layer, and which is based on its plastic coating (for example the same plastic as the depot container) the edge of the depot vessel can be sealed.

Eine besonders einfache Handhabung der erfindungsgemäßen Vorrichtung ist erreicht, wenn gemäß Anspruch 6 das Depotgefäß formschlüssig in das Schraubelement einklemmbar ist. Ein entleertes Depotgefäß wird aus dem Schraubelement herausgezogen, und ein neues Depotgefäß wird in das Schraubelement hineingesteckt.A particularly simple handling of the device according to the invention is achieved if, according to claim 6, the depot vessel can be positively clamped into the screw element. An emptied depot vessel is pulled out of the screw element and a new depot vessel is inserted into the screw element.

Ist am Rand des Gefäßes eine Dichtung vorgesehen (Anspruch 7), so wird beim Aufschrauben des Schraubelementes der Rand des Depotgefäßes gegen die Dichtung gedrückt und damit der Innenraum des Gefäßes hermetisch abgeschlossen. Auch beim Schütteln oder Drehen der zugeschraubten Vorrichtung kann keine Flüssigkeit aus der Vorrichtung austreten.If a seal is provided on the edge of the vessel (claim 7), the edge of the depot vessel is pressed against the seal when the screwing element is screwed on, thus hermetically sealing the interior of the vessel. Even when the screwed-in device is shaken or rotated, no liquid can escape from the device.

Das Depotgefäß ist besonders kostengünstig hergestellt worden, wenn es gemäß Anspruch 8 aus tiefgezogenem Kunststoff besteht.The depot vessel has been produced particularly inexpensively if it consists of thermoformed plastic.

Ist das Schraubelement als Gewindering ausgestaltet (Anspruch 9), so können wahlweise unterschiedlich hohe Depotgefäße in das Schraubelement eingesetzt werden. Die einzelnen Depotgefäße ragen dann in unterschiedlicher Höhe aus dem Gewindering heraus. Unterschiedlich hohe Depotgefäße dienen der Aufnahme unterschiedlicher Komponentenvolumina und somit unterschiedlichen Mischungsverhältnissen in der Vorrichtung.If the screw element is designed as a threaded ring (claim 9), differently high depot vessels can be inserted into the screw element. The individual depot vessels then protrude from the threaded ring at different heights. Vessels of different heights are used to hold different component volumes and thus different mixing ratios in the device.

Im folgenden wird die Erfindung anhand von Ausführungsbeispiele darstellenden Figuren näher beschrieben. Es zeigt:

Die erfindungsgemäße Vorrichtung 1 besteht aus einem offenen Gefäß 2, einem Depotgefäß 3 und einem Schraubelement 4 (Figur 1). Am oberen Rand 5 des Gefäßes 2 ist ein Schneiddorn 6 angeordnet. Das Gefäß 2 ist im oberen Bereich mit einem Außengewinde 7 versehen. Das Depotgefäß 3 ist mit einer Folie 8 verschlossen. Im Depotgefäß 3 befindet sich eine pulverförmige Komponente 9. Eine Mischung der Komponente 9 mit der flüssigen Komponente 10 im Gefäß 2 ergibt eine gebrauchsfertige Lösung. Das Schraubelement 4 ist als Gewindering 11 ausgestaltet.
Um die pulverförmige Komponente 9 in die flüssige Komponente 10 einzubringen, wird zuerst das Depotgefäß 3 in den Gewindering 11 gesteckt. Dabei verrasten drei Mitnahmenocken 12, 13, 14 des Depotgefäßes 3 in drei Mitnahmeaussparungen 15, 16, 17 des Gewinderinges 11 (Figur 1, Figur 2, Figur 3, Figur 4). Sodann wird der Gewindering 11 mittels seines Innengewindes 18 auf das Gefäß 2 aufgeschraubt. Dabei durchschneidet der Schneiddorn 6 kreisförmig die Folie 8 und die pulverförmige Komponente 9 fällt in die flüssige Komponente 10 (Figur 2).The device 1 according to the invention consists of an open vessel 2, a depot vessel 3 and a screw element 4 (FIG. 1). A cutting mandrel 6 is arranged on the upper edge 5 of the vessel 2. The vessel 2 is provided with an external thread 7 in the upper region. The depot 3 is closed with a film 8. In the depot vessel 3 there is a powdery component 9. A mixture of the component 9 with the liquid component 10 in the vessel 2 results in a ready-to-use solution. The screw element 4 is designed as a threaded ring 11.
In order to introduce the powdery component 9 into the liquid component 10, the depot vessel 3 is first inserted into the threaded ring 11. In this case, three driving cams 12, 13, 14 of the depot vessel 3 lock in three driving recesses 15, 16, 17 of the threaded ring 11 (FIG. 1, FIG. 2, FIG. 3, FIG. 4). The threaded ring 11 is then screwed onto the vessel 2 by means of its internal thread 18. The cutting mandrel 6 circularly cuts through the film 8 and the powdery component 9 falls into the liquid component 10 (FIG. 2).
