Abstract

This invention relates to an operationally reliable two-compartment container designed to prevent unintended use before application. The invention comprises a one-piece container having two compartments assembled one upon another, which are interlinked by a transfer opening into which a stopper is mounted to keep the contents of the two compartments separate during storage. The stopper is linked by supporting devices to the lower end of a pouring spout which seals the upper part of the container with a covering cap. The pouring spout is connected as a one-piece unit to an elastic membrane, which is turned inside of the container when closed, and outside when the container is opened, by which the pouring spout extends with an encompassing sealing cap into the collar region of the upper part of the compartment, is linked by a screw thread. The sealing cap is fitted with a safeguard against rotation at its junction point to the upper compartment to prevent premature removal of the covering cap, prior to admixture of the contents of the two compartments. The sealing cap includes a serration on the inside of the rim encompassing the covering cap under the sealing cap, and at least one corresponding cross-bar at the covering cap.

Description

Die vorliegende Erfindung betrifft eine neue Zweikammer-Verpackung mit gegenüber bekannten Zweikammerpackungen vereinfachtem Aufbau und verbessertem Schutz gegen mißbräuchliche oder unbeabsichtigte Betätigung.The present invention relates to a new two-chamber packaging with a simplified structure compared to known two-chamber packaging and improved protection against misuse or unintentional operation.

Zweikammer-Behälter, die insbesondere zur Konfektionierung kosmetischer Mittel, die Bestandteile enthalten, die bis zu ihrer Anwendung getrennt gehalten werden müssen, da sie sonst miteinander reagieren, vorgesehen sind, sind bereits in mannigfaltigen Erscheinungsformen bekannt geworden.Two-chamber containers, which are intended in particular for the packaging of cosmetic compositions which contain components which must be kept separate until they are used, since they otherwise react with one another, have already become known in a variety of forms.

Hinzuweisen ist beispielsweise auf den Doppelkammer-Behälter nach der DE-A 35 28 525, der aus zwei getrennt befüllbaren, übereinander liegenden, zusammensetzbaren Behälterkammern besteht, welche durch ein wenigstens einen Teil der Bodenwand der oberen Behälterkammer bildendes und die untere Behälterkammer verschließendes Trennelement gegeneinander abgeschlossen sind, das durch ein von außen betätigbares Stößelelement geöffnet werden kann, so daß die Komponenten zusammenfließen können und miteinander vermischbar sind, wobei das Trennelement als dicht in einen Durchlaßkanal zwischen der oberen und der unteren Behälterkammer eingesetzter Verschlußstopfen, der durch senkrechte Verschiebung des an ihn angreifenden Stößelelements aus dem Durchlaßkanal in eine der Behälterkammern verdrängbar ist, ausgebildet ist.Reference should be made, for example, to the double-chamber container according to DE-A 35 28 525, which consists of two separately fillable, stackable, stackable container chambers, which are sealed off from one another by a separating element forming at least part of the bottom wall of the upper container chamber and closing the lower container chamber are, which can be opened by an externally actuated plunger element, so that the components can flow together and can be mixed with one another, the separating element being inserted as a sealing plug into a passage channel between the upper and the lower container chamber, which is activated by vertical displacement of the attacking element Tappet element is displaceable from the passage into one of the container chambers.

Eine Weiterentwicklung dieser Zweikammer-Verpackung stellt der in der DE-A 38 12 343 beschriebene Doppelkammer-Behälter dar, dessen Durchlaßkanal zwischen zwei übereinander angeordneten Behälterkammern mittels eines Trennstopfens verschlossen ist, der mit einem Stößelelement verbunden ist, das als langgestreckte und sich durch die obere Behälterkammer bis in deren offene Mündung erstreckende hohle Auftragsdüse ausgebildet ist, wobei das Stößelelement auf seiner Außenseite mit einem Außengewinde versehen ist, welches mit einem komplementären Gegengewinde in Eingriff steht, das in einem von der Stirnwand eine die obere Behälterkammer zumindest teilweise übergreifenden, drehbar auf ihr gehaltenen und sie abdichtenden Drehkappe in die offene Oberseite der oberen Behälterkammer vorstehenden zylindrischen Ringvorsprung ausgebildet ist. Durch Drehen der Drehkappe im Sinne eines Hineinschraubens der Auftragsdüse in diesen Ringvorsprung ist das freie Ende der Auftragsdüse aus der Stirnwand herausdrückbar.A further development of this two-chamber packaging is the double-chamber container described in DE-A 38 12 343, the passage of which between two container chambers arranged one above the other is closed by means of a separating plug which is connected to a tappet element which is elongated and extends through the upper one Container chamber is formed into the open mouth extending hollow application nozzle, the plunger element is provided on its outside with an external thread which is in engagement with a complementary mating thread which rotates on it in an from the end wall at least partially overlapping the upper container chamber held and sealing rotary cap is formed in the open top of the upper container chamber projecting cylindrical ring projection. The free end of the application nozzle can be pushed out of the end wall by rotating the rotary cap in the sense of screwing the application nozzle into this annular projection.

Aus der DE-A 36 11 925 ist eine Taillenflasche mit in der Taillenebene angeordnetem Stopfen zur Aufteilung des Flaschenvolumens in zwei voneinander getrennte Räume, die durch Herausdrücken des Stopfens aus der Taillenebene in den der Flaschenverschlußkappe abgekehrt liegenden Raum miteinander verbindbar sind, bekannt, die so ausgestaltet ist, daß beide Räume ein relativ großes Volumen aufweisen, wobei für das Mischverhältnis beliebige Füllstände vorliegen können, aber trotzdem die zu vermischenden Komponenten sicher zusammengeführt werden. Dies wird dadurch bewerkstelligt, daß zwischen dem Stopfen und der mit dem Schraubgewinde aufsitzenden Flaschenverschlußkappe eine Stangenverbindung derart hergestellt ist, daß die Verschlußkappe eine Stoßschulter besitzt, welche auf dem Stirnende der Verbindungsstange aufliegt.From DE-A 36 11 925 a waist bottle with a stopper arranged in the waist level for dividing the bottle volume into two separate spaces, which can be connected to one another by pushing the stopper out of the waist level into the space facing away from the bottle cap, is known is designed that both rooms have a relatively large volume, and there may be any fill levels for the mixing ratio, but the components to be mixed are nevertheless safely brought together. This is accomplished in that a rod connection is made between the stopper and the bottle cap with the screw thread so that the cap has a butt shoulder which rests on the front end of the connecting rod.

Alle diese beschriebenen Zweikammer-Behälter stellen einsetzbare Verpackungssysteme dar, von denen in der Praxis auch Gebrauch gemacht wird. Sie sind jedoch relativ kompliziert aufgebaut, da sie aus vielen Einzelteilen bestehen, was ihre Fertigung und Konfektionierung verhältnismäßig teuer gestaltet.All of these two-chamber containers described are usable packaging systems, which are also used in practice. However, they are relatively complicated because they consist of many individual parts, which makes their manufacture and assembly relatively expensive.

Die vorliegende Erfindung geht daher von der Aufgabenstellung aus, einen mit einem Trennstopfen zum Verschließen von übereinander angeordneten, bis zur Anwendung getrennt gehaltenen einzelnen Abteilungen ausgestatteten Zweikammer-Behälter zu schaffen, der einfach herstellbar und konfektionierbar ist, wenig Einzelbauteile aufweist, jedoch eine sichere Trennung der bis zur Anwendung voneinander getrennt zu haltenden Produkte und, im Anwendungsfall, ein zuverlässiges Vermischen dieser Bestandteile und die Abgabe des Gemisches gestattet.The present invention is therefore based on the task of providing a two-chamber container equipped with a separating plug for closing individual departments arranged one above the other and kept separate for use, which is simple to produce and assemble, has few individual components, but does reliably separate the products to be kept separate from each other until use and, in the application, a reliable mixing of these components and the release of the mixture.

Insbesondere soll auch vermieden werden, daß durch ein versehentliches Abschrauben der Verschlußkappe ein vorzeitiges Austreten des Inhalts des oberen Behälterteils erfolgen kann.In particular, it should also be avoided that the contents of the upper container part can escape prematurely if the cap is unscrewed accidentally.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß eine Zweikammer-Verpackung geschaffen wird, die einstückig aus einem Ober- und einem Unterteil besteht, die an der Verbindungsstelle zwischen beiden durch einen Stopfen getrennt sind, welche die Merkmale des Hauptanspruchs aufweist.This object is achieved in that a two-chamber packaging is created, which consists in one piece of an upper and a lower part, which are separated at the connection point between the two by a plug, which has the features of the main claim.

Die Figuren illustrieren die erfindungsgemäße Verpackung. Figur 1 zeigt beispielhaft eine erfindungsgemäße Verpackung im geschlossenen, Figur 6 dieselbe im geöffneten Zustand.The figures illustrate the packaging according to the invention. Figure 1 shows an example of a packaging according to the invention in the closed, Figure 6 the same in the open state.

Figur 2 gibt einen Schnitt längs der Linie A-A in Figur 1, Figur 3 längs der Linie B-B, und Figur 4 längs der Linie C-C wieder; Figur 5 zeigt den Ausschnitt X aus Figur 4; Figur 7 bezieht sich auf eine äquivalente Variante der Figur 1.Figure 2 shows a section along line A-A in Figure 1, Figure 3 along line B-B, and Figure 4 along line C-C; FIG. 5 shows section X from FIG. 4; Figure 7 relates to an equivalent variant of Figure 1.

Im einzelnen besteht eine einstückig ausgebildete, vorzugsweise blasgeformte Zweikammer-Verpackung (1) aus zwei übereinander angeordneten Abteilungen (2) und (3), die durch eine Durchlaßöffnung (4), vorzugsweise mit gegenüber dem Gesamtumfang des Behältnisses reduziertem Durchmesser, miteinander verbunden sind. Diese Durchlaßöffnung ist durch einen Stopfen (5) verschlossen, der mit einem in den oberen Behälterteil (3) hineinreichenden Verbindungsglied (6) verbunden ist, das an seinem Ende ein tellerartiges Teil (7) aufweist.Specifically, a one-piece, preferably blow-molded two-chamber packaging (1) consists of two superposed compartments (2) and (3) which are connected to one another by a passage opening (4), preferably with a reduced diameter compared to the overall circumference of the container. This passage opening is closed by a stopper (5) which is connected to a connecting member (6) which extends into the upper container part (3) and which has a plate-like part (7) at its end.

Unter diesem Teil (7) rasten zwei klauen- bzw. hakenartige Halterungen (8) ein, die das untere Ende einer Ausgußtülle (9) bilden, die mit einer Abdeckkappe (10), die den oberen Behälterteil (3) abschließt, durch eine im geschlossenen Zustand zum Behälter hin gestülpte elastische Membran (11) einteilig verbunden ist. Diese Ausgußtülle (9), die an ihrem oberen Ende eine Abgabeöffnung aufweist, reicht mit einer sie umgebenden Verschlußkappe (12) bis in den oberen Behälterteil (3) hinein und ist mit dieser über ein Schraubgewinde (13) verbunden.Under this part (7) two claw-like or hook-like brackets (8) engage, which form the lower end of a pouring spout (9) with a cover cap (10) which closes the upper container part (3) by a in closed state to the container turned elastic membrane (11) is integrally connected. This pouring spout (9), which has a dispensing opening at its upper end, extends with a sealing cap (12) surrounding it into the upper container part (3) and is connected to it via a screw thread (13).

Die Verschlußkappe (12) ist an ihrer Verbindungsstelle zum oberen Behälterteil (3) mit einer Drehsicherung (14) ausgestattet, die die vorzeitige Entfernung der Verschlußkappe (12) vor dem Vermischen der Behälterinhalte (2) und (3) verhindert, und aus einer Zahnung (14 A) auf der Innenseite des über die Abdeckkappe (10) greifenden Randes der Verschlußkappe (12) und mindestens einem korrespondierenden Steg (14 B) an der Abdeckkappe (10) besteht.The closure cap (12) is equipped at its junction with the upper container part (3) with a rotation lock (14), which prevents the premature removal of the closure cap (12) before the container contents (2) and (3) are mixed, and from a set of teeth (14 A) on the inside of the edge of the closure cap (12) which extends over the cover cap (10) and at least one corresponding web (14 B) on the cover cap (10).

Durch das Ineinandergreifen der Zahnung (14 A) und der Stege (14 B) ist es nicht möglich, die Verschlußkappe (12) abzuschrauben, bevor die Inhalte der Behälterteile (2) und (3) tatsächlich vereinigt sind.Due to the interlocking of the teeth (14 A) and the webs (14 B), it is not possible to unscrew the cap (12) before the contents of the container parts (2) and (3) are actually combined.

Die Figur 2 zeigt einen Schnitt längs der Linie A-A in Figur 1 und stellt das Verbindungsglied (6) dar.Figure 2 shows a section along the line AA in Figure 1 and represents the connecting member (6).

Die Figur 3 zeigt einen Schnitt längs der Linie B-B in Figur 1 und stellt das untere Ende (8) der Ausgießtülle (9) dar, das vorzugsweise in Form von mindestens zwei Klauen oder Haken ausgestaltet ist, die sich beim Montageprozeß über das vorzugsweise tellerartig ausgebildete obere Ende (7) des Verbindungsgliedes (6) schieben, sich aufspreizen und sich so irreversibel mit dem oberen Ende des Verbindungsgliedes (6) verbinden.FIG. 3 shows a section along the line BB in FIG. 1 and represents the lower end (8) of the pouring spout (9), which is preferably designed in the form of at least two claws or hooks, which are formed during the assembly process by the preferably plate-shaped one Push the upper end (7) of the connecting member (6), spread apart and thus irreversibly connect to the upper end of the connecting member (6).

Die Figur 4 zeigt die Zahnung (14 A) in ihrer Verbindung mit den Stegen (14 B) analog der Schnittlinie C-C nach Figur 1.FIG. 4 shows the toothing (14 A) in connection with the webs (14 B) analogous to the section line C-C according to FIG. 1.

Dabei ist die Abdeckkappe (10) mit der Behälterwandung durch eine Prellverbindung (15), wie sie in Figur 1 dargestellt ist, fest verbunden, wobei vorzugsweise noch eine umlaufende Dichtlippe (16) vorhanden ist.The cover cap (10) is firmly connected to the container wall by a bump connection (15), as shown in FIG. 1, a circumferential sealing lip (16) preferably also being present.

Figur 5 gibt die Anordnung der Zahnung (14 A) und der Stege (14 B) entsprechend dem Ausschnitt X aus Figur 4 nochmals im vergrößerten Detail wieder.Figure 5 shows the arrangement of the teeth (14 A) and the webs (14 B) according to the detail X of Figure 4 again in enlarged detail.

Figur 6 zeigt eine erfindungsgemäße Zweikammer-Verpackung in gebrauchsfertigem, d.h., geöffneten Zustand.Figure 6 shows a two-chamber packaging according to the invention in a ready-to-use, i.e. opened state.

Dieser Prozeß erfolgt in zwei Schritten:
Die Verschlußkappe (12) wird mit Hilfe der an ihrer Spitze befindlichen Handhabe (17) nach oben gezogen, wodurch der Stopfen (5) über die Verbindung zwischen unterem Ende (8) der Ausgußtülle (9) und dem Verbindungsglied (6) aus der Durchlaßöffnung (4) entfernt, und dadurch der Inhalt des unteren Behälterteils (2) und des oberen Behälterteils (3) miteinander vermischt wird. Dabei wird die elastische Membran (11) nach außen gestülpt.This process takes place in two steps:
The closure cap (12) is pulled up with the aid of the handle (17) located at its tip, as a result of which the stopper (5) via the connection between the lower end (8) of the pouring spout (9) and the connecting member (6) from the passage opening (4) removed, and thereby the contents of the lower container part (2) and the upper container part (3) are mixed together. The elastic membrane (11) is turned outwards.

Durch die Bewegung der Verschlußkappe (12) wird auch die Verbindung zwischen der Zahnung (14 A) und den Stegen (14 B) an der Abdeckkappe (10) aufgehoben. Dadurch wird ein Abschrauben der im Ruhezustand blockierten Verschlußkappe (12) ermöglicht.The movement of the closure cap (12) also removes the connection between the teeth (14 A) and the webs (14 B) on the cover cap (10). This makes it possible to unscrew the closure cap (12) which is blocked in the idle state.

Durch das Umstülpen der Membran (11) nach außen kommt es im Behältnis (1) zwangsläufig zu einem Volumenzuwachs und, dadurch bedingt, zum Aufbau eines Vakuums.By turning the membrane (11) inside out, there is inevitably an increase in volume in the container (1) and, as a result, a vacuum is built up.

Andererseits entsteht durch die Reaktion der Behälterinhalte durch Gasbildung (CO₂) ein Überdruck. Es ist daher anzustreben, durch entsprechende Dosierung der Behälterinhalte die Einstellung eines Gleichgewichts im Sinne eines Druckausgleichs zu bewirken.On the other hand, the reaction of the container contents through gas formation (CO₂) creates an overpressure. It is therefore desirable to achieve an equilibrium in the sense of pressure equalization by appropriately dosing the container contents.

Noch zweckmäßiger ist es jedoch, das entstandene Vakuum nicht komplett zu egalisieren, sondern einen schwachen Unterdruck im Behältnis aufrechtzuerhalten.However, it is even more expedient not to completely equalize the vacuum that has arisen, but to maintain a weak negative pressure in the container.

Dies hat zur Folge, daß erst beim Abschrauben der Verschlußkappe (12) der Unterdruck durch die einströmende Luft kompensiert und dadurch eventuell bereits in der Ausgußtülle (9) befindliche Flüssigkeit in den Behälter zurückgesaugt wird.The consequence of this is that the vacuum is only compensated for by the inflowing air when the closure cap (12) is unscrewed, and any liquid that is already in the pouring spout (9) is sucked back into the container.

Figur 6 zeigt eine zu Figur 1 äquivalente Ausführungsform, wobei die Halterungen (7) zwischen Verbindungsglied (6) und dem unteren Ende (8) der Ausgußtülle (9) als komplementär ineinander eingreifende Haken gestaltet sind.Figure 6 shows an embodiment equivalent to Figure 1, wherein the brackets (7) between the connecting member (6) and the lower end (8) of the pouring spout (9) are designed as complementary interlocking hooks.

Es sind natürlich noch weitere äquivalente Abwandlungen denkbar.Of course, other equivalent modifications are also conceivable.

Die Füllung und Konfektionierung der erfindungsgemäßen Zweikammer-Verpackung erfolgt auf denkbar einfache Weise: Zunächst wird das untere Behälterteil (2) mit einer Lösung, Emulsion, Dispersion, etc. gefüllt, dann die Durchlaßöffnung (4) durch den Stopfen (5) verschlossen, das obere Behälterteil (3) gefüllt, und anschließend die Verschlußkappe (12) mit ihren integrierten Teilen aufgebracht und das Gesamtbehältnis (1) verschlossen.The two-chamber packaging according to the invention is filled and packaged in a very simple manner: first, the lower container part (2) is filled with a solution, emulsion, dispersion, etc., then the passage opening (4) is closed by the stopper (5), which filled the upper container part (3), and then applied the closure cap (12) with its integrated parts and closed the entire container (1).

Gemäß einer in den Figuren 8a und 8b dargestellten weiteren bevorzugten Ausführungsform der Erfindung wird die Verschlußkappe (12) mit der Schulter der Abdeckkappe (10) durch Schweißen, z. B. im Ultraschallverfahren, mittels entsprechender Verschweißzapfen (19) bzw. -punkten verbunden.According to a further preferred embodiment of the invention shown in Figures 8a and 8b, the closure cap (12) with the shoulder of the cover cap (10) by welding, for. B. in the ultrasonic process, connected by means of appropriate welding spigot (19) or points.

Figur 8a zeigt dabei einen Schnitt durch die Verschlußkappe (12); Figur 8b stellt eine Draufsicht auf die Abdeckkappe (10) dar.Figure 8a shows a section through the cap (12); Figure 8b shows a top view of the cover cap (10).

Durch die Verschweißung werden die Membran (11) und die Halterungen (7, 8) mit definierter Kraft in ihrer Position fixiert, der Stopfen (5) wird gegen ein unbeabsichtigtes vorzeitiges Öffnen, z.
