Ein solcher Doppelbehälter mit einem Drehscheibenverschluß ist aus der DE-A 24 44 227 bekannt, wobei dieser für die Entnahme von vorgegebenen Mischungsverhältnissen mittels einer entsprechenden Lochscheibe vorgesehen ist und kompliziert im Aufbau und daher störanfällig ist und umständlich in der Handhabung.Such a double container with a turntable closure is known from DE-A 24 44 227, which is provided for the removal of predetermined mixing ratios by means of a corresponding perforated disk and is complicated in structure and therefore prone to failure and cumbersome to handle.

Aufgabe der Erfindung ist es daher, den bekannten Doppelbehälter so zu verbessern, daß eine hohe Betriebssicherheit durch wenige und einfach gestaltete, leicht zusammenbare Einzelteile bei kostengünstigere Massenfertigung erreicht wird, leicht zu bedienen ist und ein stufenloses Entnahmemischungsverhältnis ermöglicht.The object of the invention is therefore to improve the known double container so that a high level of operational safety is achieved by a few and simply designed, easily assembled individual parts with less expensive mass production, is easy to use and enables a continuous removal mixture ratio.

Gelöst wird diese Aufgabe dadurch, daß die Verschlußstücke als nach innen gerichtete Fortsätze der Austrittsdüse ausgebildet sind, die in im Ansatz des inneren Verschlußteils befindliche Nuten eingreifen, deren äußere und innere Wände jeweils die Austrittsöffnungen aufweisen, wobei die Verschlußstücke und Austrittsöffnungen jeweils paarweise einander gegenüberliegen, und daß das Volumenverhältnis vom Innenbehälter zum Außenbehälter den Wert 1: 2 nicht überschreitet:This object is achieved in that the closure pieces are designed as inwardly directed extensions of the outlet nozzle, which engage in grooves located in the attachment of the inner closure part, the outer and inner walls of which each have the outlet openings, the closure pieces and outlet openings lying opposite one another in pairs, and that the volume ratio of the inner container to the outer container does not exceed the value 1: 2:

Der erfindungsgemäße Behälter hat den Vorteil, daß er einfach und platzsparend aufgebaut ist. Er besitzt nur wenige und einfach gestaltete Einzelteile, die sich leicht zusammensetzen lassen, so daß eine kostengünstige Massenfertigung möglich und eine höhe Betriebssicherheit gewährleistet ist sowie ein stufenloses Entnahmemischungsverhältnis ermöglicht.The container according to the invention has the advantage that it is simple and space-saving. It has only a few and simply designed individual parts that are easy to assemble, so that cost-effective mass production is possible, high operational reliability is ensured and a continuous removal mixture ratio is made possible.

Der Doppelbehälter besteht aus dem lnnenbehälter 1, dem Außenbehälter 2 und dem Drehverechluß 3 mit Austrittsdüse 4. Der Drehverschluß 3 besitzt ein kappenförmiges äußeres Verschlußteil 5, das auf einem kappenförmigen inneren Verschlußteil 6 drehbar gelagert ist. Beide Verschlußteile 5 und 6 sind durch eine Schnappverbindung 7 miteinander verbunden. Das äußere Verschlußteil 5 weist einen kreissektorförmigen Schlitz 8 auf, in den ein am inneren Verschlußteil 6 befestigter Anschlag 9 hineinragt. Die Austrittsdüse 4 ist am äußeren Verschlußteil 5 befestigt und hat an ihrem unteren Teil zwei gegenüberliegende Verschlußstücke 10 und 11, zwischen denen sich freie Zwischenräume 12 und 13 befinden, und einen ringförmigen Ansatz 14. Die freien Zwischenräume 12 und 13 bilden die Eintrittsöffnungen für die Flüssigkeit in die Austrittsdüse 4. Das innere Verschlußteil 6 ist anseinem Rand mit einem Innengewinde zum Aufschrauben auf das Außengewinde 16 am Hals des Außenbehälters 2 versehen und besitzt einen nach innen ragenden hohlen Ansatz 17, der ebenfalls ein Innengewinde 18 zum Aufschrauben auf das Außengewinde am Hals des Innenbehälters 1 aufweist. Eine kreisförmige Dichtungslippe 19, die in den Hals des Außenbehälters 2 hineinragt, sorgt für eine Abdichtung dieses Behälters nach außen, während eine weitere Dichtungslippe 20 in den Ansatz 14 an der Austrittsdüse 4 hineinragt und äußeres und inneres Verschlußteil 5 und 6 gegeneinander abdichtet. Im Ansatz 17 befinden sich zwei gegenüberliegende Austrittsöffnungen 21 und 22 für die Flüssigkeit im Außenbehälter 2 und zwei einander gegenüberliegende Austrittsöffnungen 23 und 24 für die Flüssigkeit im Innenbehälter 1. Am Rand des äußeren Verschlußteils 5 befinden sich drei Durchbrüche 25, die aus fertigungstechnischen Gründen wegen der drei darunterliegenden Nocken der Schnappverbindung 7 vorgesehen sind, um nach dem Spritzen das äußere Verschlußteil aus der Spritzgießform entfernen zu können. Zum Verschluß der Austrittsdüse 4 kann eine Steckverschlußkappe 4a Verwendung finden. Es kann aber auch ein Abbrech- oder Schraubverschluß vorgesehen sein.The double container consists of the inner container 1, the outer container 2 and the rotary lock 3 with an outlet nozzle 4. The rotary lock 3 has a cap-shaped outer closure part 5 which is rotatably mounted on a cap-shaped inner closure part 6. Both closure parts 5 and 6 are connected to one another by a snap connection 7. The outer closure part 5 has a circular sector-shaped slot 8, into which a stop 9 attached to the inner closure part 6 projects. The outlet nozzle 4 is fastened to the outer closure part 5 and has at its lower part two opposing closure pieces 10 and 11, between which there are free spaces 12 and 13, and an annular extension 14. The free spaces 12 and 13 form the inlet openings for the liquid into the outlet nozzle 4. The inner closure part 6 is provided at its edge with an internal thread for screwing onto the external thread 16 on the neck of the outer container 2 and has an inwardly projecting hollow extension 17 which also has an internal thread 18 for screwing onto the external thread at the neck of the Has inner container 1. A circular sealing lip 19, which protrudes into the neck of the outer container 2, seals this container to the outside, while a further sealing lip 20 protrudes into the extension 14 on the outlet nozzle 4 and seals the outer and inner closure parts 5 and 6 against one another. In the approach 17 there are two opposite outlet openings 21 and 22 for the liquid in the outer container 2 and two opposite outlet openings 23 and 24 for the liquid in the inner container 1. At the edge of the outer closure part 5 there are three openings 25, which for manufacturing reasons because of three underlying cams of the snap connection 7 are provided in order to be able to remove the outer closure part from the injection mold after injection molding. A plug cap 4a can be used to close the outlet nozzle 4. But it can also be a cancel or Screw closure may be provided.

In der Stellung des äußeren Verschlußteils 5 nach Fig. und 2 verschließen die Verschlußstücke 10 und 11 die Austrittsöffnungen 21 und 22, so daß beim Knautschen des Außenbehälters 2 mit der Hand Flüssigkeit vom Innenbehälter 1 durch die Öffnungen 23 und 24 aus der Austrittsdüse 4 austritt, wenn sich der Doppelbehälter in der Gebrauchsstellung befindet, wie dies aus Fig. 6 ersichtlich ist. Wird das äußere Verschlußteil 5 um 90° gedreht, so daß der Anschlag 9 am anderen Ende des Schlitzes 8 anliegt und das Verschlußteil 5 in der Stellung nach Fig. 3 bis 5 ist, dann sind die Austrittsöffnungen 21 und 22 offen und die Austrittsöffnungen 23 und 24 durch die Verschlußstücke 10 und 11 geschlossen. In diesem Fall tritt Flüssigkeit des Außenbehälters 2 aus der Austrittsdüse 4 aus, wie dies Fig. 7 zeigt. In den beiden Endstellungen des äußeren Verschlußteils 5 ist entweder der Außenbehälter 2 oder der Innenbehälter 1 verschlossen, so daß also nur der Innenbehälter oder nur der Außenbehälter entleert werden kann, wie dies in den Figuren durch Pfeile angedeutet ist. Nimmt dagegen das äußere Verschlußteil 5 Zwischenstellungen zwischen den Stellungen nach Fig. 2 und 4 ein, dann können beide Flüssigkeiten der Behälter-1 und 2 in einem von der Stellung des Verschlußteils 5 abhängigen Verhältnis miteinander gemischt werden.In the position of the outer closure part 5 according to FIGS. 2 and 2, the closure pieces 10 and 11 close the outlet openings 21 and 22, so that when the outer container 2 is crimped, liquid from the inner container 1 emerges from the outlet nozzle 4 through the openings 23 and 24, when the double container is in the position of use, as can be seen from FIG. 6. If the outer closure part 5 is rotated by 90 °, so that the stop 9 bears against the other end of the slot 8 and the closure part 5 is in the position according to FIGS. 3 to 5, then the outlet openings 21 and 22 are open and the outlet openings 23 and 24 closed by the closure pieces 10 and 11. In this case, liquid of the outer container 2 emerges from the outlet nozzle 4, as shown in FIG. 7. In the two end positions of the outer closure part 5, either the outer container 2 or the inner container 1 is closed, so that only the inner container or only the outer container can be emptied, as is indicated in the figures by arrows. If, on the other hand, the outer closure part 5 assumes intermediate positions between the positions according to FIGS. 2 and 4, then both liquids of the containers 1 and 2 can be mixed with one another in a ratio dependent on the position of the closure part 5.

Um die Funktion des Doppelbehälters zu gewährleisten, müssen Innen- und Außenbehälter in ihrem Volumen so aufeinander abgestimmt sein, daß der Außenbehälter 2 zum Entleeren der beiden Flüssigkeiten geknautscht werden kann, ohne daß dessen Wandinnenfläche die Wandaußenfläche des Innenbehälters 1 berührt, da dieser sich infolge der verschlossenen Austrittsöffnungen 23 und 24 nicht oder nur wenig verformen läßt. Aus diesem Grund ist es zweckmäßig, wenn das Volumenverhältnis der beiden Behälter den Wert von 1: 2 nicht überschreitet. Günstige Werte sind 1: 3, 1: 4 und 1: 5. nen aus Kunststoff gespritzt sein. In den Innenbehälter 1 kann beispielsweise ein Shampoo und in den Außenbehälter 2 ein Kurmittel für die Haarbehandlung eingefüllt scin, so daß zuerst Shampoo und anschließend Kurmittel ausgegeben wird.In order to ensure the function of the double container, the volume of the inner and outer containers must be matched to one another so that the outer container 2 can be crumpled to empty the two liquids without the inner wall surface of the outer container touching the outer container surface 1, since this is due to the closed outlet openings 23 and 24 can not or only slightly deform. For this reason, it is useful if the volume ratio of the two containers does not exceed 1: 2. Favorable values are 1: 3, 1: 4 and 1: 5. In the inner container 1, for example, a shampoo and in the outer container 2 a treatment for the hair treatment can be scin, so that first shampoo and then treatment is dispensed.
