Die Erfindung betrifft einen Mehrkammerbehälter für schüttbare Substanzen, insbesondere Flüssigkeiten, bei welchem die Innenräume eines ersten und eines zweiten Behälterteils durch mindestens eine Folie voneinander getrennt sind und eine Vorrichtung zum Durchtrennen der Folie vorgesehen ist.The invention relates to a multi-chamber container for pourable substances, in particular liquids, in which the interiors of a first and a second container part are separated from one another by at least one film and a device is provided for severing the film.

Für Flüssigkeiten, jedoch auch andere schüttbare Substanzen wie Pulver und Granulate, sind Behälter bekannt, die eine getrennte Aufbewahrung mehrerer Substanzen ermöglichen und bei denen die Substanzen kurz vor der Verwendung gemischt werden können.For liquids, but also other pourable substances such as powders and granules, containers are known which allow separate storage of several substances and in which the substances can be mixed shortly before use.

Einer der bekannten Mehrkammerbehälter (DE-U 77 07 618) besteht aus zwei übereinander angeordneten, miteinander lösbar verbundenen Dosen, die gegeneinander verschiebbar geführt und so auf Abstand voneinander gehalten sind, daß eine ihre Innenräume voneinder trennende Folie durch Verringern des Abstandes zwischen den Dosen trennbar ist. Dabei kann der Abstand durch Drehen verringert werden, wenn gemäß einer Weiterbildung des bekannten Mehrkammerbehälters die Dosen mit einem Gewinde versehen sind. Dieser bekannte Mehrkammerbehälter ist jedoch recht aufwendig in der Herstellung.One of the known multi-chamber containers (DE-U 77 07 618) consists of two superposed, releasably connected cans, which are guided against one another and are kept at a distance from one another so that a film separating their interiors can be separated by reducing the distance between the cans is. The distance can be reduced by turning if, according to a development of the known multi-chamber container, the cans are provided with a thread. However, this known multi-chamber container is quite complex to manufacture.

Ein anderer bekannter Mehrkammerbehälter (EP-A 0 101 594) besteht aus jeweils einem einteiligen Bodenbehälter und einem einteiligen Kopfbehälter, welche durch eine Trennfolie voneinander getrennt sind. In dem deformierbaren Bodenbehälter ist ein an den Querschnitt des Behälters angepaßtes Stanzwerkzeug vorgesehen, welches bei Deformierung des Bodenbehälters die Trennfolie durchstößt. Bei diesem bekannten Mehrkammerbehälter ist ein relativ großer Kraftaufwand zum Durchstoßen der Trennfolie erforderlich.Another known multi-chamber container (EP-A 0 101 594) consists of a one-part bottom container and a one-part head container, which are separated from one another by a separating film. In the deformable bottom container, a punching tool is provided which is adapted to the cross section of the container and which pierces the separating film when the bottom container is deformed. In this known multi-chamber container, a relatively large amount of force is required to pierce the separating film.

Aufgabe der vorliegenden Erfindung ist es, einen Mehrkammerbehälter anzugeben, der mit geringem Aufwand herstellbar ist und der einfach zu befüllen und bei der Mischung und Anwendung der Substanzen leicht zu handhaben ist.The object of the present invention is to provide a multi-chamber container which can be produced with little effort and which is easy to fill and easy to handle when mixing and using the substances.

Der erfindungsgemäße Mehrkammerbehälter ist dadurch gekennzeichnet, daß im ersten Behälterteil eine Spindel vorgesehen ist, auf welcher die Vorrichtung zum Durchtrennen drehbar gelagert ist, und daß eine drehbare Betätigungsvorrichtung verdrehfest mit der Vorrichtung zum Durchtrennen verbunden ist.The multi-chamber container according to the invention is characterized in that a spindle is provided in the first container part, on which the device for severing is rotatably mounted, and that a rotatable actuating device is connected in a rotationally fixed manner to the device for severing.

Der erfindungsgemäße Mehrkammerbehälter ist zur Aufnahme verschiedener schüttbarer Substanzen geeignet. Eine bevorzugte Anwendung besteht in der Verpackung von Haarfärbemitteln, wobei im ersten Behälterteil eine Peroxid-Lösung und im zweiten Behälterteil die Farbmasse aufbewahrt wird.The multi-chamber container according to the invention is suitable for holding various pourable substances. A preferred application is in the packaging of hair dyes, with the first container part a peroxide solution and the paint is stored in the second part of the container.

Eine Weiterbildung des erfindungsgemäßen Mehrkammerbehälters besteht darin, daß die Betätigungsvorrichtung und die Vorrichtung zum Durchtrennen zueinander axial verschiebbar sind und daß die Betätigungsvorrichtung gegen axiale Verschiebung gesichert ist. Hierdurch wird die Handhabbarkeit des erfindungsgemäßen Mehrkammerbehälters weiter verbessert.A further development of the multi-chamber container according to the invention is that the actuating device and the device for severing are axially displaceable relative to one another and that the actuating device is secured against axial displacement. This further improves the manageability of the multi-chamber container according to the invention.

Vorteilhafte Ausgestaltungen des erfindungsgemäßen Mehrkammerbehälters bestehen darin, daß die Betätigungsvorrichtung einen ringförmigen Teil aufweist und daß der ringförmige Teil das erste Behälterteil teilweise umschließt und als Standring ausgebildet ist.Advantageous embodiments of the multi-chamber container according to the invention consist in that the actuating device has an annular part and that the annular part partially surrounds the first container part and is designed as a standing ring.

Weitere vorteilhafte Ausgestaltungen betreffen die Lagerung und die Verbindung der Betätigungsvorrichtung mit der Vorrichtung zum Durchtrennen. So kann vorgesehen sein, daß die Betätigungsvorrichtung ferner einen Drehzapfen aufweist, welcher in einer axial verlaufenden Bohrung der Spindel gelagert ist und dessen in den Innenraum des ersten Behälterteils weisendes Ende als Mitnehmer für die Vorrichtung zum Durchtrennen ausgebildet ist. Dabei ist vorteilhaft, daß der Drehzapfen mit einem umlaufenden Wulst versehen ist, der zusammen mit einer in der Bohrung umlaufenden Nut eine axiale Sicherung der Betätigungsvorrichtung darstellt.Further advantageous refinements relate to the mounting and the connection of the actuating device to the severing device. Thus, it can be provided that the actuating device further has a pivot which is mounted in an axially running bore of the spindle and whose end pointing into the interior of the first container part is designed as a driver for the device for severing. It is advantageous that the pivot is provided with a circumferential bead, which together with a circumferential groove in the bore represents an axial securing of the actuating device.

Zur Abdichtung des Innenraums des ersten Behälterteils kann an der Spindel mindestens ein Dichtring vorgesehen sein.To seal the interior of the first container part, at least one sealing ring can be provided on the spindle.

Um ein Durchtrennen der Folie durch eine relativ kurze Drehung zu erzielen, ist gemäß einer anderen Weiterbildung der Erfindung vorgesehen, daß die Spindel ein Steilgewinde aufweist.In order to cut through the film by a relatively short rotation, it is provided according to another development of the invention that the spindle has a steep thread.

Andere Weiterbildungen betreffen vorteilhafte Ausgestaltungen der Vorrichtung zum Durchtrennen. So kann beispielsweise vorgesehen sein, daß die Vorrichtung zum Durchtrennen eine Spindelmutter und mindestens einen, sich in radialer und axialer Richtung erstrekkenden Arm aufweist, dessen von der Spindelmutter abgewandtes Ende als Schneide ausgebildet ist. Dabei können mehrere Arme vorgesehen sein, die im Bereich der Schneiden ringförmig miteinander verbunden sind.Other developments relate to advantageous refinements of the severing device. For example, it can be provided that the device for severing has a spindle nut and at least one arm, which extends in the radial and axial directions and whose end facing away from the spindle nut is designed as a cutting edge. A plurality of arms can be provided, which are connected to one another in a ring shape in the area of the cutting edges.

Zur Verbesserung des Mischvorgangs kann gemäß einer anderen Weiterbildung die Vorrichtung zum Durchtrennen Einrichtungen zur Verbesserung des Durchmischens der Substanzen, insbesondere Leitschaufeln, aufweisen.To improve the mixing process, according to another development, the device for severing can have devices for improving the mixing of the substances, in particular guide vanes.

Eine weitere vorteilhafte Ausgestaltung des erfindungsgemäßen Mehrkammerbehälters besteht darin, daß die Behälterteile an jeweils der dem anderen Behäl-terteil zugewandten Fläche mit einer Folie verschlossen sind, daß eines der Behälterteile eine umlaufen de Kante aufweist und daß das andere Behälterteil mit einem die umlaufende Kante umfassenden Schnappring versehen ist. Hierdurch ist einerseits ein einfaches Zusammenfügen der Behälterteile nach deren Füllung gewährleistet. Andererseits ergibt sich eine sichere Abdichtung der Behälter gegeneinander und nach außen.A further advantageous embodiment of the multi-chamber container according to the invention is that the container parts are sealed with a film on the surface facing the other container part, that one of the container parts has a circumferential edge and that the other container part has a snap ring encompassing the circumferential edge is provided. On the one hand, this ensures simple assembly of the container parts after they have been filled. On the other hand, there is one secure sealing of the containers against each other and to the outside.

Die Entnahme der gemischten Substanzen wird gemäß einer anderen Weiterbildung dadurch erleichtert, daß das erste Behälterteil knautschbar ist.According to another further development, the removal of the mixed substances is facilitated in that the first container part can be crushed.

Schließlich besteht eine vorteilhafte Ausgestaltung darin, daß das zweite Behälterteil eine Entnahmeöffnung aufweist und daß die Innenwand des zweiten Behälterteils mindestens im Bereich der Entnahmeöffnung mit Rippen versehen ist.Finally, an advantageous embodiment is that the second container part has a removal opening and that the inner wall of the second container part is provided with ribs at least in the region of the removal opening.

Die Erfindung läßt zahlreiche Ausführungsformen zu. Zwei davon sind schematisch in der Zeichnung an Hand mehrerer Figuren dargestellt und nachfolgend beschrieben. Es zeigt jeweils als Längsschnitt

  • Fig. 1 ein erstes Ausführungsbeispiel und
  • Fig. 2 ein zweites Ausführungsbeispiel.
The invention allows numerous embodiments. Two of these are shown schematically in the drawing using several figures and described below. It shows a longitudinal section
  • Fig. 1 shows a first embodiment and
  • Fig. 2 shows a second embodiment.

Gleiche Teile sind in den Figuren mit gleichen Bezugszeichen versehen.Identical parts are provided with the same reference symbols in the figures.

Der in Fig. 1 dargestellte Mehrkammerbehälter besteht aus einem ersten Behälterteil 1 - im folgenden Unterteil genannt - und einem zweiten Behälterteil 2 - im folgenden Oberteil genannt. Beide Teile sind in an sich bekannter Weise aus Kunststoff hergestellt. Die Innenräume der Behälterteile sind durch Folien 3, 4 voneinander getrennt, so daß jeweils ein Behälterteil eine Substanz aufnimmt. Das Oberteil 2 umfaßt eine Entnahmeöffnung 5, welche mit einem Drehverschluß 6 verschließbar ist. Zur Verbindung der beiden Behälterteile miteinander ist am Oberteil 2 eine umlaufende Kante 7 vorgesehen, während das Unterteil mit einem Schnappring 8 versehen ist, der beim Zusammenfügen der Behälterteile über die umlaufende Kante 7 des Oberteils 2 gleitet, dabei radial verformt wird und sich wieder zusammenzieht, sobald der ringförmige Absatz 9 die umlaufende Kante 7 überschritten hat.The multi-chamber container shown in Fig. 1 consists of a first container part 1 - hereinafter called the lower part - and a second container part 2 - hereinafter called the upper part. Both parts are made of plastic in a manner known per se. The interiors of the container parts are separated from one another by foils 3, 4, so that one container part each holds a substance. The upper part 2 comprises a removal opening 5 which can be closed with a rotary closure 6. To connect the two container parts with each other, a circumferential edge 7 is provided on the upper part 2, while the lower part is provided with a snap ring 8 which slides over the circumferential edge 7 of the upper part 2 when the container parts are joined, is radially deformed and contracts again as soon as the annular Paragraph 9 has exceeded the circumferential edge 7.

Am Boden des Unterteils befindet sich eine, einstückig mit dem Unterteil verbundene Spindel 10, welche ein Steilgewinde 11 aufweist. Im Eingriff mit der Spindel 10 befindet sich eine Spindelmutter 12, die ebenfalls aus Kunststoff besteht und Arme 13, 14 aufweist, deren Enden einen Ring 15 tragen, der mit zwei Schneiden 16, 17 versehen ist.At the bottom of the lower part there is a spindle 10, which is connected in one piece to the lower part and has a steep thread 11. In engagement with the spindle 10 there is a spindle nut 12, which is also made of plastic and has arms 13, 14, the ends of which bear a ring 15 which is provided with two cutting edges 16, 17.

Zur Drehung der Spindelmutter und damit zum gleichzeitigen Drehen und Heben der Schneiden 16, 17 ist eine Betätigungsvorrichtung 18 vorgesehen, die einen Zapfen 19 aufweist, der in einer axialen Bohrung der Spindel 10 gelagert ist. Des weiteren ist die Betätigungsvorrichtung als Ring 20 ausgebildet, der zur Drehung leicht mit einer Hand ergriffen werden kann, während die andere Hand den Mehrkammerbehälter festhält. Der Ring 20 umschließt einen Teil des Unterteils, der mit kleinerem Radius ausgebildet ist. Dadurch entsteht ein umlaufender Absatz 21, auf den sich der Ring 20 abstützt. Dadurch und durch eine entsprechende Ausbildung des unteren Randes des Ringes 20 wird ein sicherer Stand des Mehrkammerbehälters gewährleistet.For the rotation of the spindle nut and thus for the simultaneous rotation and lifting of the cutting edges 16, 17, an actuating device 18 is provided which has a pin 19 which is mounted in an axial bore of the spindle 10. Furthermore, the actuating device is designed as a ring 20, which can be easily gripped for rotation with one hand while the other hand holds the multi-chamber container. The ring 20 encloses a part of the lower part which is designed with a smaller radius. This creates a circumferential shoulder 21 on which the ring 20 is supported. This and a corresponding design of the lower edge of the ring 20 ensures a secure stand of the multi-chamber container.

Um zu vermeiden, daß bei der Drehung des Ringes 20 dieser eine axiale Bewegung vollführt, ist die verdrehfeste Verbindung (beispielsweise in Form eines Vier- oder Sechskants) zwischen dem Zapfen 19 und der Spindelmutter 12 axial verschiebbar ausgeführt. Ferner ist durch einen umlaufenden Wulst 22, der in eine umlaufende Nut 23 eingreift, die Betätigungsvorrichtung 18 gegen eine axiale Verschiebung bzw. Herausfallen gesichert. Eine Dichtlippe 24 dichtet den Innenraum des Unterteils 1 gegenüber der Bohrung in der Spindel ab.In order to avoid that when the ring 20 rotates axially, the non-rotatable connection (for example in the form of a square or hexagon) between the pin 19 and the spindle nut 12 is made axially displaceable. Furthermore, the actuating device 18 is secured against axial displacement or falling out by a circumferential bead 22 which engages in a circumferential groove 23. A sealing lip 24 seals the interior of the lower part 1 from the bore in the spindle.

Das Montieren und Befüllen des erfindungsgemäßen Mehrkammerbehälters läuft wie folgt ab: In das Unterteil 1 wird die Vorrichtung zum Durchtrennen der Folie eingesetzt, wobei die Spindelmutter 12 auf die Spindel 10 aufgeschraubt wird. Danach wird die Betätigungsvorrichtung 18 in die Bohrung der Spindel 10 bis zum Einschnappen eingeführt. Das Unterteil kann dann befüllt und mit einer Folie 3 verschweißt werden. Die Verschlußkappe 6 wird auf das Oberteil 2 aufgeschraubt, worauf das Oberteil 2 kopfstehend befüllt und mit der Folie 4 verschweißt wird. Die beiden Behälterteile werden dann gegeneinander gepreßt, so daß der Schnappring 8 über die umlaufende Kante 7 schnappt.The assembly and filling of the multi-chamber container according to the invention takes place as follows: The device for cutting through the film is inserted into the lower part 1, the spindle nut 12 being screwed onto the spindle 10. Then the actuator 18 is inserted into the bore of the spindle 10 until it snaps into place. The lower part can then be filled and welded with a film 3. The closure cap 6 is screwed onto the upper part 2, whereupon the upper part 2 is filled upside down and welded to the film 4. The two container parts are then pressed against each other so that the snap ring 8 snaps over the peripheral edge 7.

Zum Mischen der beiden Substanzen wird der Ring 20 gegenüber dem Unterteil 1 um etwas mehr als eine Umdrehung gedreht, wobei sich die Schneiden 16, 17 entlang der Außenwand des Unterteils 1 nach oben bewegt. Dabei taucht die Schneide in die Folien ein und schneidet diese kreisförmig durch. Durch kräftiges Schütteln werden die beiden Substanzen vermischt. Es erfolgt eine Unterstützung des Mischvorgangs durch die entsprechend ausgebildeten Arme 13, 14. Der Vier- bzw. Sechskant ist kürzer als das Gewinde 11, so daß die Spindelmutter 12 auf der Spindel verbleibt, wenn die Folien 3, 4 durchtrennt sind. Die Vorrichtung zum Durchtrennen der Folie bleibt also beim Schütteln des Behälters an ihrer Stelle. Nach dem Lösen der Verschlußkappe 6 kann die Mischung durch leichtes Knautschen des kopfstehenden Behälters entnommen werden.To mix the two substances, the ring 20 is rotated by a little more than one turn relative to the lower part 1, the cutters 16, 17 moving upward along the outer wall of the lower part 1. The cutting edge dips into the foils and cuts them in a circle. The two substances are mixed by shaking vigorously. The mixing process is supported by the appropriately designed arms 13, 14. The square or hexagon is shorter than the thread 11, so that the spindle nut 12 remains on the spindle when the foils 3, 4 are severed. The device for severing the film thus remains in its place when the container is shaken. After loosening the cap 6, the mixture can be removed by gently crumpling the upside down container.

Als Werkstoff für das Oberteil 2 und die Betätigungsvorrichtung 18 eignet sich Polypropylen oder Polystyrol. Das knautschbare Unterteil 1 kann aus Polyethylen hergestellt werden. Eine andere, an den jeweiligen Verwendungszweck angepaßte Werkstoffauswahl bleibt dem Fachmann überlassen.Polypropylene or polystyrene is suitable as the material for the upper part 2 and the actuating device 18. The crushable lower part 1 can be made of polyethylene. Another selection of materials adapted to the respective intended use is left to the person skilled in the art.

Bei der in Fig. 2 dargestellten Ausführungsform sind die Behälterteile und die Betätigungsvorrichtung an sich ähnlich wie bei der Ausführungsform nach Fig. 1 ausgebildet. Es ist jedoch das Oberteil 2 knautschbar ausgeführt. Auch die Vorrichtung zum Durchtrennen der Folie weicht gegenüber der Ausführungsform nach Fig. 1 ab. Und zwar sind die Schneiden 25, 26 an einem Schneidringkörper 27 angeordnet, welcher aus einem Ring 28 und vier Armen, von denen drei Arme 29, 30, 31 dargestellt sind, besteht. Zur Verbesserung des Mischvorgangs sind die Arme mit Leitschaufeln 32, 33 versehen. Außerdem ist in einer umlaufenden Nut 34 des Zapfens 35 eine weitere Dichtung 36 angeordnet.In the embodiment shown in FIG. 2, the container parts and the actuating device per se are designed similarly to the embodiment according to FIG. 1. However, the upper part 2 is designed to be crushable. The device for severing the film also differs from the embodiment according to FIG. 1. Namely, the cutting edges 25, 26 are arranged on a cutting ring body 27, which consists of a ring 28 and four arms, of which three arms 29, 30, 31 are shown. The arms are provided with guide vanes 32, 33 to improve the mixing process. In addition, a further seal 36 is arranged in a circumferential groove 34 of the pin 35.

Gegenüber den entsprechenden Teilen beim Ausführungsbeispiel nach Fig. 1 sind das Unterteil 37 und der Ring 38 etwas anders gestaltet, was jedoch im wesentlichen nur einen ästhetischen Effekt hat.Compared to the corresponding parts in the exemplary embodiment according to FIG. 1, the lower part 37 and the ring 38 are designed somewhat differently, but this has essentially only an aesthetic effect.

Ferner sind bei dem Ausführungsbeispiel nach Fig. 2 mehrere Rippen 39, 40 an der Innenwand des Oberteils 2 vorgesehen. Damit wird verhindert, daß die ausgeschnittene Folie die Entnahmeöffnung 5 verdeckt und somit eine Entleerung des Behälters beeinträchtigt. In Fig. 2 sind lediglich zwei Rippen dargestellt; die Anzahl und die Form der Rippen im einzelnen kann im Rahmen des Fachmännischen gewählt werden.2, a plurality of ribs 39, 40 are provided on the inner wall of the upper part 2. This prevents the cut-out film from covering the removal opening 5 and thus impairing the emptying of the container. In Fig. 2 only two ribs are shown; the number and shape of the ribs in detail can be selected within the scope of the expert.
