Sie besitzt zwei Kammern 11,13, deren Wandungen durch eine Rippe 15 miteinander verbunden sind. Die Kammern 11,13 können verschieden gross sein und auch verschiedene Formen aufweisen. Die Rippe 15 wird beim Schliessen der Blasform gebildet, indem die beiden Blasformhälften den Schlauch entlang einer praktisch vertikalen Linie zusammenpressen, so dass die beiden gegenüberliegenden Wände miteinander verbunden werden. Dabei entstehen auch die in Figur 2 sichtbaren Einbuchtungen 17. Die Kammern 11,13 besitzen im Bereich des Stutzens 19 Oeffnungen 21,23, welche innerhalb oder unterhalb dieses gemeinsamen Stutzens 19 münden. Die Oeffnung 23 ist vorteilhaft kalibriert. Dies ermöglicht eine dichte Verbindung mit dem Verschluss. Eine kreisförmige Ausbildung und koaxiale Anordnung der Oeffnung 23 zum Stutzen 19 ermöglichen die Verwendung eines mit Gewinde versehenen Verschlusses. Zu diesem Zweck kann am Stutzen ein Aussengewinde 20 vorgesehen sein. Es wäre aber auch möglich, ein Innengewinde am Stutzen 19 vorzusehen. Es sind aber auch andere Befestigungsmittel möglich, z.B. eine Schnappvorrichtung wie in Figur 5. Die Oeffnung 23 befindet sich im Stutzenboden 25. Die andere Oeffnung 21 ist praktisch halbkreisförmig. Es wäre aber auch möglich, diese Oeffnung kreisförmig, oval oder mit einer anderen Formgebung auszubilden.The multi-chamber bottle 10 shown in FIGS. 1 to 4 can be made from plastic using the blowing process. she owns two chambers 11, 13, the walls of which are separated by a rib 15 are interconnected.

Zu diesem Zweck sind am Deckel 42 Zapfen 44,46 vorgesehen, welche beim Verschliessen des Deckels 42 in die Ausgussöffnungen 39,40 eindringen. Es ist auch möglich, den Deckel 42 gewissermassen zu teilen, also für jede Ausgussöffnung 39,40 einen separaten Deckel vorzusehen, so dass jede Kammer 11,13 unabhängig von einer anderen Kammer entleert werden kann. Auch ein so ausgebildeter Verschluss kann einstückig gefertigt werden.As shown in FIG. 4, a neck 10 of the bottle 10 is on Screwed on closure 27. This is useful made in one piece from plastic. The closure 27 has a flange 33 which projects into the socket 19 and this seals. The closure also has channels 35, 37 which from the openings 21, 23 of the chambers 11, 13 to the Lead pouring openings 39.40. For fastening the lock 27 serves a thread 41, which on the thread 20 of the Nozzle 19 fits. For example with a film hinge on the closure body 28 hinged cover 42 serves the Closing the pouring openings 39.40. For this purpose on the lid 42 pins 44, 46 are provided, which when closing of the lid 42 penetrate into the pouring openings 39, 40. It is also possible to divide the cover 42 to a certain extent, that is for to provide a separate lid for each pouring opening 39, 40 that each chamber 11, 13 is independent of another chamber can be emptied. A closure designed in this way can also be made in one piece.

Der koaxial zum Stutzen 19 angeordnete Kanal 37 ist durch einen rohrförmigen Ansatz 43 gebildet. Dieser Ansatz 43 ist derart bemessen, dass er bei aufgesetztem Verschluss 27 dichtend in die zweckmässigerweise kalibrierte Oeffnung 23 eingreift.The channel 37 arranged coaxially to the connector 19 is through a tubular neck 43 formed. This approach 43 is like this dimensioned so that it seals in the appropriately calibrated opening 23 engages.

Bei der Ausführungsform gemäss den Figuren 5 und 6 ist keine der Oeffnungen 21,23 konzentrisch zum Stutzen 19 angeordnet. Dementsprechend ist auch der Verschluss 27 nicht aufschraubbar ausgebildet. Der Unterschied zum Verschluss von Figur 4 besteht somit im wesentlichen darin, dass anstelle eines Gewindes Rastnasen 41' vorgesehen sind, welche an einem ringförmigen Wulst 20' des Stutzens 19 einrasten können. Im übrigen ist der Verschluss 27 gleich wie jener von Figur 4 ausgebildet, so dass auf die dortige Beschreibung verwiesen werden kann.In the embodiment according to FIGS. 5 and 6 there is none the openings 21, 23 arranged concentrically to the nozzle 19. Accordingly, the closure 27 cannot be screwed on educated. The difference to the closure of Figure 4 is thus essentially in that instead of a thread Lugs 41 'are provided, which on an annular Bead 20 'of the socket 19 can snap into place. Otherwise, the Closure 27 is the same as that of Figure 4, so that can be referred to the description there.

Das Ausführungsbeispiel von Figur 7 zeigt eine Dreikammerflasche 10' mit den Kammern 11,13 und 14. Die Dreikammerflasche ist analog zur Zweikammerflasche gemäss den Figuren 5 und 6 ausgebildet, so dass auf die vorangegangene Beschreibung verwiesen werden kann. Statt eine Rippe sind zwei Rippen 15' vorgesehen, die ebenfalls über einen wesentlichen Teil der Flasche senkrecht verlaufen. Der Verschluss 27' ist so ausgebildet, dass alle drei Kammern 11,13,14 mit einer Ausgussöffnung 39,40 in Verbindung stehen.The embodiment of Figure 7 shows one Three-chamber bottle 10 'with the chambers 11, 13 and 14. The The three-chamber bottle is analogous to the two-chamber bottle according to the Figures 5 and 6 designed so that to the previous Description can be referenced. Instead of one rib there are two Ribs 15 'are provided, which also have an essential Part of the bottle is vertical. The closure 27 'is like this trained that all three chambers 11,13,14 with a Spout opening 39.40 are connected.

Die Mehrkammerflasche 10" gemäss dem dritten Ausführungsbeispiel nach den Figuren 8 und 9 ist mindestens im Bereich des Stutzens 19 praktisch spiegelsymmetrisch ausgebildet. Die Oeffnungen 21,23 der Kammern 11,13 haben somit praktisch die gleiche Ausbildung. Sie sind relativ gross und erleichtern so das Abfüllen der Flasche.The multi-chamber bottle 10 "according to the third Embodiment according to Figures 8 and 9 is at least in Area of the nozzle 19 practically mirror-symmetrical educated. The openings 21, 23 of the chambers 11, 13 thus have practically the same training. They are relatively large and make filling the bottle easier.

Entsprechend der Ausbildung der Flasche ist auch der Verschluss 27" weitgehend symmetrisch ausgebildet. Die Kanäle 35,37 werden durch eine Trennwand 49 voneinander getrennt, welche an der Verbindungsstelle 51 der beiden Kammern 11 und 13 aufliegt. Diese Verbindungsstelle 51 ist gewissermassen ein auf ein schmales Band verkleinerter Stutzenboden 25 gemäss Fig.6. Durch die Trennwand 49 wird zwar keine perfekte Abdichtung zwischen den beiden Kammern 11 und 13 erreicht, aber für viele Verwendungszwecke der Mehrkammerflasche dürfte dies genügen. So ist beispielsweise für pasteuse Produkte kaum eine Gefahr einer störenden Vermischung vorhanden.The closure also corresponds to the design of the bottle 27 "largely symmetrical. The channels 35,37 are separated from each other by a partition 49, which on the connection point 51 of the two chambers 11 and 13 rests. This connection point 51 is, as it were, one on one narrow band of reduced nozzle base 25 according to FIG. 6. By the partition 49 is not a perfect seal between reached the two chambers 11 and 13, but for many This should suffice for the uses of the multi-chamber bottle. So is hardly a danger for pasteuse products, for example disruptive mixing present.

Der Verschluss 27" weist einen Deckel 42 auf, der mit einem Filmscharnier 53 mit dem Verschlusskörper 28 verbunden ist. Wie bereits früher erwähnt,. kann der Verschluss auch separate Deckel für die verschiedenen Ausgussöffnungen aufweisen, aber trotzdem auch einstückig gefertigt werden.The closure 27 "has a cover 42 which is connected to a Film hinge 53 is connected to the closure body 28. How mentioned earlier. the closure can also be separate Have lids for the different pouring openings, however still be made in one piece.

Als Befestigungsmittel zum Aufsetzen auf die Flasche kann dieser Verschluss ein Gewinde 41 aufweisen. Es kann aber auch eine Schnappvorrichtung zur Anwendung gelangen.Can be used as a fastener for placement on the bottle this closure has a thread 41. But it can also a snap device are used.

Es sind verschiedene Aenderungen möglich, ohne von der Erfindung abzuweichen. So können verschiedene Merkmale der gezeigten Ausführungsformen kombiniert werden, z.B. statt einem Gewinde ein Schnappverschluss vorgesehen werden.Different changes are possible without changing the Deviate invention. So different characteristics of the shown embodiments can be combined, e.g. instead of one Thread a snap lock can be provided.
