Description

Die Erfindung betrifft einen Zweikammerbehälter nach der Gattung des Oberbegriffs des Anspruchs 1.The invention relates to a two-chamber container according to the preamble of claim 1.

Ein derartiger Behälter ist zum Beispiel durch die gattungsbildende DE-U-89 00 291 der Anmelderin bekannt. Dieser Behälter dient dazu, zwei verschiedene flüssige Produkte bis zum Gebrauch getrennt aufzubewahren. Zum Gebrauch werden die Produkte zu einer Mischung zusammengeführt, die dann über einen Verschluß entnehmbar ist.Such a container is known, for example, from the generic DE-U-89 00 291 of the applicant. This container is used to store two different liquid products separately until use. For use, the products are combined into a mixture which can then be removed via a closure.

Der Erfindung liegt die Aufgabe zugrunde, einen gattungsgleichen Behälter zu schaffen, mit dem es bei einfacher Handhabung möglich ist, zusätzlich eine begrenzte Teilmenge nur des einen Produkts zu entnehmen.The invention has for its object to provide a generic container with which it is possible with simple handling to additionally remove a limited subset of only one product.

Diese Aufgabe wird gelöst nach den Merkmalen des kennzeichnenden Teils des Anspruchs 1. Vorteilhafte Weiterbildungen/Ausgestaltungen der Erfindung gehen aus den Unteransprüchen hervor.This object is achieved according to the features of the characterizing part of claim 1. Advantageous further developments / refinements of the invention emerge from the subclaims.

Dadurch, daß ein rohrartiger Stößel vorgesehen ist, der in einer Grundstellung einerseits mit seinem ersten Ende mit dem Gewinde der Drehkappe flüssigkeitsdicht verbunden ist und andererseits mit seinem anderen zweiten Ende durch den Stopfen hindurch in die untere Kammer hineinragt, wobei der Stößel mit dem Stopfen flüssigkeitsdicht verbunden ist, ist eine begrenzte Teilmenge nur des einen Produkts aus der unteren Kammer entnehmbar. Dies ist beispielsweise anwendungstechnisch im Friseurbereich vorteilhaft, um zunächst nur mit dem einen Produkt in begrenzter Menge einen ersten Haarbehandlungsschritt vorzunehmen. Für einen zweiten Haarbehandlungsschritt mit einem Produktgemisch wird eine Kappe gedreht, dann der Behälter kurz geschüttelt und anschließend appliziert.Characterized in that a tubular plunger is provided, which is connected in a basic position on the one hand with its first end to the thread of the rotary cap and on the other hand protrudes with its other second end through the plug into the lower chamber, the plunger with the plug being liquid-tight is connected, a limited subset of only one product can be removed from the lower chamber. This is advantageous, for example, in terms of application technology in the hairdressing sector, initially only with one Product in a limited amount to carry out a first hair treatment step. For a second hair treatment step with a product mixture, a cap is turned, then the container is shaken briefly and then applied.

Anhand von drei Ausführungsbeispielen wird die Erfindung näher beschrieben.The invention is described in more detail using three exemplary embodiments.

Ein erstes Ausführungsbeispiel eines Zweikammerbehälters 1 ist in der Figur 1 dargestellt. Der Behälter 1 dient für getrennt zu haltende, fließfähige Stoffe 2, 3, wobei zur Trennung einer oberen und unteren Kammer 4, 5 eine Taillenflasche 6 mit in einer Taillenebene 7 angeordneten Stopfen 8 vorgesehen ist. Zum Zusammenführen der beiden Stoffe 2, 3 innerhalb des Behälters 1 wird der Stopfen 8 durch manuelles Drehen einer Drehkappe 9 durch einen Stößel 10 aus der Taillenebene 7 in die untere Kammer 5 hineingedrückt, wobei dazu die Drehkappe 9 mit einem in die obere Kammer 4 weisenden Gewinde 11 versehen ist und ein am Stößel 10 angeordneter Gewindeabschnitt 12 in das Gewinde 11 der Drehkappe 9 spindelantriebsartig eingreift. Im Endbereich des Gewindeabschnitts 12 sind Durchtrittsöffnungen 13 vorgesehen für einen Durchtritt der Stoffmischung 2, 3. Zum Entnehmen der Stoffe 2, 3 ist die Drehkappe 9 mit einem Verschluß 14 versehen. Der Stößel 10 ist rohrartig ausgestaltet, der in einer Grundstellung einerseits mit seinem ersten Ende (30) mit dem Gewinde 11 der Drehkappe flüssigkeitsdicht verbunden ist und andererseits mit seinem anderen zweiten Ende (31) durch den Stopfen 8 hindurch in die untere Kammer 5 hineinragt, wobei der Stößel 10 mit dem Stopfen 8 flüssigkeitsdicht verbunden ist.A first exemplary embodiment of a two-chamber container 1 is shown in FIG. 1. The container 1 is used for separate, flowable substances 2, 3, a waist bottle 6 with plugs 8 arranged in a waist plane 7 being provided for separating an upper and lower chamber 4, 5. To bring the two substances 2, 3 together within the container 1, the stopper 8 is pressed into the lower chamber 5 by manually rotating a rotary cap 9 by means of a plunger 10 from the waist plane 7, the rotary cap 9 for this purpose pointing into the upper chamber 4 Thread 11 is provided and a threaded portion 12 arranged on the plunger 10 engages in the thread 11 of the rotary cap 9 like a spindle drive. In the end region of the threaded section 12, through openings 13 are provided for the material mixture 2, 3 to pass through Rotating cap 9 provided with a closure 14. The plunger 10 is of tubular design, which in a basic position is connected on the one hand with its first end (30) to the thread 11 of the rotary cap in a liquid-tight manner and on the other hand projects with its other second end (31) through the stopper 8 into the lower chamber 5, wherein the plunger 10 is connected to the plug 8 in a liquid-tight manner.

Die linke Seite der Figur 1 zeigt den Behälter 1 in einem Lagerungszustand, also vor Entnahme der Stoffe 2, 3; die rechte Seite der Figur 1 zeigt den Behälter 1 mit in die untere Kammer 5 hineingedrücktem Stopfen 8 und mit einem Stoffgemisch 2, 3, wobei ein Teil des Stoffs 3 zuvor entnommen ist durch das in die Kammer 5 hineinragende Rohr 15. An dem Rohr 15 sind vier radial angeordnete Flügel 18 angeformt, wobei die obere Kammer 4 mit zwei gegenüberliegenden Flaschenwandeinbuchtungen 20, 20 versehen ist, die im Zusammenspiel mit den Flügeln 18 ein Führungsgleitlager bzw. eine Verdrehsicherung des Stößels 10 darstellen für eine Art Spindelantrieb des Stößels 10.The left side of FIG. 1 shows the container 1 in a storage state, that is to say before the substances 2, 3 are removed; the right-hand side of FIG. 1 shows the container 1 with the plug 8 pressed into the lower chamber 5 and with a mixture of substances 2, 3, part of the substance 3 having been removed beforehand through the pipe 15 projecting into the chamber 5. On the pipe 15 Four radially arranged vanes 18 are formed, the upper chamber 4 being provided with two opposite bottle wall indentations 20, 20 which, in interaction with the vanes 18, constitute a guide sliding bearing or an anti-rotation device for the plunger 10 for a kind of spindle drive for the plunger 10.

Zum Befüllen des Behälters 1 wird zunächst die untere Kammer 5 der Taillenflasche 6 ohne Drehkappe 9 und Stößel 10/Stopfen 8 über eine Öffnung 16 mit einem flüssigen Stoff 3 befüllt. Dann wird der Stopfen 8 zusammen mit dem Stößel 10 in die Öffnung 16 gedrückt. Dazu ist der rohrartige Stößel 10 mit einem Mitnehmering 21 versehen, der so bemessen ist, daß der Stopfen 8 von der Axialkraft des Stößels 10 in den Sitz der Taillenöffnung 16 gedrückt werden kann. Nach dem Befüllen der oberen Kammer 4 mit dem Stoff 2 erfolgt ein Aufdrehen der Kappe 9 auf den Gewindeabschnitt 12 und ein Aufprellen auf den Rastring 17.To fill the container 1, the lower chamber 5 of the waist bottle 6 without the rotating cap 9 and plunger 10 / stopper 8 is first filled with a liquid substance 3 via an opening 16. Then the plug 8 is pressed together with the plunger 10 into the opening 16. For this purpose, the tubular plunger 10 is provided with a driving ring 21 which is dimensioned such that the plug 8 can be pressed into the seat of the waist opening 16 by the axial force of the plunger 10. After the upper chamber 4 has been filled with the substance 2, the cap 9 is screwed onto the threaded section 12 and bounced onto the locking ring 17.

Zum Entnehmen einer Teilmenge wird zunächst der Verschluß 14 geöffnet und eine durch die vorgegebene Länge des Rohrs 15 begrenzte Menge des Stoffs 3 entnommen. Zum weiteren Entnehmen eines Stoffgemisches 2, 3 werden diese zunächst dadurch zusammengeführt, daß durch Drehen der Kappe 9 der Mitnehmering 21 den Stopfen 8 nach unten in die untere Kammer 5 hineindrückt, wodurch der Stoff 2 aus der oberen Kammer 4 über die nun freigewordene Öffnung 16 in die untere Kammer 5 fließt und durch Schütteln des Behälters 1 eine Stoffmischung 2, 3 ergibt. Bei diesem Ausführungsbeispiel ist ein Vorteil darin zu sehen, daß der Stopfen 8 hinsichtlich seiner Dichtungseigenschaft aus einem hierzu besonders geeigneten Material bestehen kann. Das Ende des Kammertrennungsaufhebevorgangs wird dadurch signalisiert, daß das untere Ende der Flügel 18 auf einen Boden 22 der oberen Kammer 4 aufstößt und dadurch ein weiteres Drehen der Kappe 9 verhindert wird (rechte Seite der Figur 1). Es kann anwendungstechnisch vorgesehen werden, daß die Stoffe 2, 3 beim Vermischungsvorgang sich verdicken. Hierzu ist zwecks besserer Entnahme der verdickten Stoffmischung 2, 3 vorgesehen, den Verschlußteil 23 mit seiner relativ kleinen Öffnung 24 abbrechbar mittels eines Abbrechringes 25 auszubilden, wodurch eine größere Entnahmeöffnung erreicht ist.To remove a partial quantity, the closure 14 is first opened and a quantity of the substance 3 limited by the predetermined length of the tube 15 is removed. To further remove a mixture of substances 2, 3, these are first merged in that by rotating the cap 9 of the driving ring 21 pushes the stopper 8 down into the lower chamber 5, whereby the substance 2 flows from the upper chamber 4 through the now cleared opening 16 into the lower chamber 5 and by shaking the container 1 results in a mixture of substances 2, 3. In this embodiment, an advantage can be seen in the fact that the plug 8 can consist of a material that is particularly suitable for this with regard to its sealing property. The end of the chamber separation lifting process is signaled by the fact that the lower end of the wings 18 strikes a bottom 22 of the upper chamber 4 and thereby prevents the cap 9 from rotating further (right side of FIG. 1). In terms of application technology, it can be provided that the substances 2, 3 thicken during the mixing process. For this purpose, for better removal of the thickened substance mixture 2, 3, it is provided that the closure part 23 with its relatively small opening 24 is designed to be breakable by means of a break-off ring 25, as a result of which a larger removal opening is achieved.

Beim zweiten Ausführungsbeispiel eines Behälters 1A nach den Figuren 3 und 4 ist der Stößel 10A und der Stopfen 8A einteilig ausgestaltet, wodurch ein Teil reduziert ist. Die linke Seite der Figur 3 zeigt den Behälter 1A in einem Lagerungszustand bzw. vor Gebrauch; die rechte Seite der Figur 3 zeigt den Behälter 1A nach einer Aufhebung der Kammertrennung.In the second exemplary embodiment of a container 1A according to FIGS. 3 and 4, the plunger 10A and the stopper 8A are designed in one piece, as a result of which a part is reduced. The left side of FIG. 3 shows the container 1A in a storage state or before use; the right-hand side of FIG. 3 shows the container 1A after the chamber separation has been lifted.

Figur 4 zeigt den Behälter 1A nach der Figur 3 in einer Position unmittelbar nach dem Befüllen der beiden Stoffe 2, 3, wozu der Behälter 1A noch ohne Drehkappe 9 ist und der Stopfen 8A eine höherliegende Verschlußposition aufweist. Das Befüllen der unteren Kammer 5 mit einem Stoff 3 kann durch die Öffnung 16 erfolgen und nach dem Aufsetzen des Stopfens 8A das Befüllen der oberen Kammer 4 mit einem Stoff 2 durch die freistehenden Flügel 18, wie nach Pfeil 26 angedeutet. Es kann aber auch ein gleichzeitiges Befüllen nach der Figur 4 vorgesehen werden, nämlich gleichzeitiges Befüllen der unteren Kammer 5 durch das Rohr 15A und der oberen Kammer 4 durch Pfeil 26. Nach dem Befüllungsvorgang wird auf den Gewindeabschnitt 12 die Kappe 9 gedreht und abschließend auf den Rastring 17 geprellt. Dieser Prellvorgang macht einen gewissen axialen Weg des Stopfens 8A erforderlich, weswegen der Stopfen 8A eine entsprechend lange Ausgestaltung wegen der Dichtfunktion aufweist.FIG. 4 shows the container 1A according to FIG. 3 in a position immediately after the two substances 2, 3 have been filled, for which purpose the container 1A is still without a rotating cap 9 and the stopper 8A has a higher-lying closure position. The lower chamber 5 can be filled with a substance 3 through the opening 16 and after the plug 8A has been placed on it, the upper chamber 4 can be filled with a substance 2 through the free-standing wings 18, as indicated by arrow 26. But it can also be a simultaneous one Filling can be provided according to FIG. 4, namely simultaneous filling of the lower chamber 5 through the pipe 15A and the upper chamber 4 by arrow 26. After the filling process, the cap 9 is rotated on the threaded section 12 and finally chipped onto the locking ring 17. This bouncing process requires a certain axial path of the plug 8A, which is why the plug 8A has a correspondingly long configuration because of the sealing function.

Beim dritten Ausführungsbeispiel eines Behälters 1B nach den Figuren 5 und 6 ist der Stößel 10B als ein verlängerter Stopfen 8B ausgestaltet, wodurch der Stopfen 8B gleichzeitig als Rohr 15B wirkt. Ansonsten gilt die Beschreibung nach der Figuren 5 und 6.In the third exemplary embodiment of a container 1B according to FIGS. 5 and 6, the plunger 10B is designed as an elongated plug 8B, as a result of which the plug 8B simultaneously acts as a tube 15B. Otherwise, the description according to FIGS. 5 and 6 applies.
