Kunststoffbehälter bekannt, welche in einer Behälterkammer eine integrierte Abgabeeinrichtung zur Abgabe von in der Behälterkammer aufgenommenen Substraten in einen Mischbehälter aufweist. Der Kunststoffbehälter ist häufig als Behälterverschluss ausgebildet oder wird bei Verwendung auf eine Mischbehälteröffnung aufgesetzt. Bei Betätigung der Abgabeeinrichtung wird der Behälter geöffnet und das Substrat aus der Behälterkammer in den Mischbehälter abgegeben. Plastic container known, which has an integrated dispensing device for dispensing received in the container chamber substrates in a mixing container in a container chamber. The plastic container is often designed as a container closure or is placed in use on a mixing container opening. Upon actuation of the dispenser, the container is opened and the substrate is dispensed from the container chamber into the mixing container.
Die Kunstoffbehälter umfassen jeweils einen Behälterkörper, einen Durchstosser und eine Siegelfolie. Dabei bildet der Behälterkörper den Behälterinnenraum resp. die Behälterkammer zur Aufnahme von festen oder flüssigen Substraten, wie beispielsweise feste, rieselförmige oder flüssige Wirkstoffe, Getränkezusätze, Reagenzien, etc., aus, welcher durch die Siegelfolie verschlossen ist. Im Behälterinnenraum ist der Durchstosser derart bewegbar aufgenommen, das eine Betätigung des Durchstosser, diesen in Richtung Siegelfolie bewegt und dabei die Siegelfolie durchtrennt. Das im Behälterinnenraum aufgenommen Substrat kann aus dem Behälter austreten. Die Betätigung des Durchstosser kann mittels einer flexiblen, gewölbten Membran erfolgen oder ein Teil des Durchstosser ist dichtend durch die Behälterwand geführt und direkt betätigbar.  The plastic containers each comprise a container body, a piercer and a sealing foil. In this case, the container body forms the container interior respectively. the container chamber for receiving solid or liquid substrates, such as solid, free-flowing or liquid agents, beverage additives, reagents, etc., which is closed by the sealing film. In the container interior of the piercing is so movably received, which moves an actuation of the piercing, this in the direction of sealing film and thereby severing the sealing film. The substrate received in the container interior can escape from the container. The operation of the piercing can be done by means of a flexible, curved membrane or a part of the piercing is sealingly guided by the container wall and directly operable.
US6003728 zeigt eine Alternative zur Siegelfolie. Dabei ist die Behälterkammer mit einem aufstossbaren, unteren Verschlussdeckel anstelle der Siegelfolie verschlossen, welcher mittels einer umlaufenden Wulst in einer Nut der Behälterwand kraftschlüssig aufgenommen ist. Der Verschlussdeckel kann über eine schmale Scharnierbrücke mit der Behälterwand verbunden sein und ragt in der Offenstellung im wesentliche senkrecht in den Mischbehälter. Der Durchstosser wirkt mittig auf den Verschlussdeckel. Zur Abgabe muss der Verschlussdeckel mit relativ grossem Kraftaufwand aus der Rastverbindung gedrückt werden und „springt" dann in die Offenstellung. Dabei kann es Vorkommen, dass auch die Scharnierbrücke bricht und der Verschlussdeckel in den Mischbehälter fällt. US6003728 shows an alternative to the sealing film. In this case, the container chamber with a push-up, lower cap instead sealed the sealing film, which is received non-positively by means of a circumferential bead in a groove of the container wall. The closure lid can be connected via a narrow hinge bridge with the container wall and protrudes in the open position essentially vertically into the mixing container. The piercer acts centrally on the cap. To discharge the cap must be pressed with relatively great force from the latching connection and then "jumps" in the open position, there may be occurrence that also breaks the hinge bridge and the cap falls into the mixing container.
Nachteilig an den bekannten Kunststoffbehältern ist, dass sie aus mehreren Teilen zusammengesetzt sind, welche separat gefertigt und anschliessen in einem weiteren Verfahrensschritt zusammengesetzt werden. Dies kostet Zeit und Geld. A disadvantage of the known plastic containers is that they are composed of several parts, which are manufactured separately and subsequently assembled in a further method step. This costs time and money.
Ein weiterer Nachteil bei den bekannten Behältervorrichtungen ist, dass die durchtrennte Folie oder der ausgeschwenkte Verschlussdeckel häufig in die Flüssigkeit des Mischbehälters eintauchen und in dieser Offenstellung verbleiben. Anschliessend ist es kaum möglich, den Kunststoffbehälter sauber vom Mischbehälter zu entfernen. Auch ist die Bauweise der bekannten Behälter mit integrierter Abgabeeinrichtung meist komplex und aufwendig. Zudem ist ein Aufreissen oder Aufschneiden der Siegelfolie nicht kontrollierbar und die Handhabe des Kunststoffbehälters wird daher fehleranfällig.

Der Behälterkörper umfasst eine Behälterwand und einen in einem unteren Bereich angeordneten Behälterboden, wobei an einem oberen dem Behälterboden gegenüberliegenden Ende des Behälterkörpers eine Behälteröffnung ausgebildet ist. Im oberen Bereich umfasst der Behälterkörper eine umlaufende obere Umrandung. Die Behälterabdeckung zum Abdecken der Behälteröffnung ist an der oberen Umrandung des Behälterkörpers befestigbar. Die obere Umrandung ist von einer oberen Kante der Behälterwand in Bezug auf eine Behälterachse radial nach aussen beabstandet. Die obere Umrandung ist über einen gelenkigen Verbindungsabschnitt mit der Behälterwand verbunden, wobei der gelenkige Verbindungsabschnitt eine Verschiebung der oberen Umrandung relativ zur Behälterwand und zum Öffnungsmittel erlaubt, so dass der Kunststoffbehälter von einer Geschlossenstellung in eine Offenstellung bringbar ist.  The container body comprises a container wall and a container bottom arranged in a lower region, wherein a container opening is formed at an upper end of the container body opposite the container bottom. In the upper area of the container body comprises a circumferential upper border. The container cover for covering the container opening is attachable to the upper border of the container body. The upper rim is spaced radially outwardly from an upper edge of the container wall with respect to a container axis. The upper border is connected via an articulated connecting portion with the container wall, wherein the articulated connecting portion allows a displacement of the upper edge relative to the container wall and the opening means, so that the plastic container can be brought from a closed position to an open position.
Durch die relative Verschiebung wird das mit der Behälterwand wirkverbundene Öffnungsmittel zur Öffnung der Behälterabdeckung gegen die mit der oberen Umrandung ortsfest wirkverbundene Behälterabdeckung gedrückt.  As a result of the relative displacement, the opening means, which is operatively connected to the container wall, is pressed against the opening of the container cover against the container cover which is fixedly connected to the upper border.
Das gelenkige Verbindungselement ermöglicht dabei eine einfache Herstellung eines Kunststoffbehälters mit integrierter Abgabe- oder Öffnungseinrichtung für ein im Kunststoffbehälter aufgenommenes Substrat, wobei Behälterkörper und Behälterabdeckung einen Behälterinnenraum für das Substrat definieren. Dabei kann eine obere Kante der Behälterwand als Öffnungsmittel für die Behälterabdeckung ausgebildet sein, wie weiter unten noch ausgeführt wird. Alternativ ist es auch möglich ein separates Öffnungsmittel, z.B. einen Durchstosser im Behälterinnenraum anzuordnen. The articulated connection element allows a simple production of a plastic container with integrated dispensing or opening device for a recorded in the plastic container substrate, wherein container body and container cover define a container interior for the substrate. In this case, an upper edge of the container wall may be formed as an opening means for the container cover, as will be explained below. Alternatively, it is also possible to arrange a separate opening means, for example a piercer in the container interior.
Die Behälterachse ist mittig durch den Behälterboden und die Behälteröffnung definiert, wobei die Behälterwand nicht kreiszylindrisch um die Behälterachse ausgebildet sein muss, sondern auch andere Formen aufweisen kann.  The container axis is defined centrally through the container bottom and the container opening, wherein the container wall does not have to be circular cylindrical formed around the container axis, but may also have other shapes.
Weitere Ausführungsarten der Erfindung sind in den abhängigen Ansprüchen angegeben.  Further embodiments of the invention are specified in the dependent claims.
In einigen Ausführungsformen kann das Öffnungsmittel in der Geschlossenstellung unterhalb der Behälterabdeckung resp. innerhalb des Behälters liegen und in der Offenstellung derart nach oben versetzt sein, dass die Behälterabdeckung durchschnitten, durchstossen oder aufgedrückt wird. In some embodiments, the opening means in the closed position below the container cover resp. lie within the container and be offset in the open position so that the container cover is cut, pierced or pushed.
In einigen Ausführungsformen kann der gelenkige Verbindungsabschnitt in der Geschlossenstellung im Querschnitt gesehen im Wesentlichen Schlaufen- oder U-förmig ausgebildet ist. Bei einer Verschiebung der oberen Umrandung in die Offenstellung wird der gelenkige, Schlaufen- oder U-förmige Verbindungsabschnitt gestreckt. Dabei kann er eine Rückstellkraft erzeugen, um eine Rückverschiebung der oberen Umrandung in die Geschlossenstellung zu begünstigen. Die maximale Verschiebung kann in etwa der Länge des Verbindungsabschnitts entsprechen, d.h. in etwa der zweifachen Länge eines Schenkels des Schlaufen- oder U-förmigen Verbindungsabschnitts. In some embodiments, in the closed position, the hinged connection portion may be substantially loop-shaped or U-shaped when viewed in cross-section. With a displacement of the upper border in the open position of the articulated, loop or U-shaped connecting portion is stretched. He can generate a restoring force to favor a return shift of the upper border in the closed position. The maximum displacement may be approximately equal to the length of the connection portion, i. in about twice the length of a leg of the loop or U-shaped connecting portion.
In einigen Ausführungsformen kann der gelenkige Verbindungsabschnitt als flexible und/oder elastische Dünnstelle ausgebildet sein. In der Regel ist der gelenkige Verbindungsabschnitt dünner ausgestaltet als eine Normwandstärke der Behälterwand. Behälterwand und obere Umrandung können im Wesentlichen die gleiche Wandstärke aufweisen.  In some embodiments, the articulated connection portion may be formed as a flexible and / or elastic thin point. In general, the articulated connection portion is made thinner than a standard wall thickness of the container wall. Container wall and upper border can have substantially the same wall thickness.
In einigen Ausführungsformen kann die obere Umrandung eine Wand ausbilden, welche im Wesentliche parallel zur Behälterwand verläuft. Das untere Ende der Wand kann mit dem gelenkigen Verbindungsabschnitt verbunden sein. An der oberen Umrandung resp. am oberen Ende der Wand kann ein umlaufender nach aussen gerichteter Flansch ausgebildet sein. In einigen Ausführungsformen kann die obere Umrandung über den Verbindungsabschnitt integral an der Behälterwand angeformt sein. Der Behälterkörper kann einstückig z.B. mittels Spritzguss gefertigt sein. In some embodiments, the upper border may form a wall that is substantially parallel to the vessel wall. The lower end of the wall may be connected to the articulated connection portion. At the upper border resp. At the upper end of the wall may be formed a circumferential outwardly directed flange. In some embodiments, the upper border may be integrally formed with the container wall via the connecting portion. The container body may be manufactured in one piece, for example by means of injection molding.
In einigen Ausführungsformen kann die Behälterabdeckung ein Behälterdeckel mit mehreren Klappen sein und die obere Kante der Behälterwand das Öffnungsmittel ausbilden. Diese kann beispielsweise derart angeordnet und ausgestaltet sein, dass es den mehrere Klappen aufweisenden Behälterdeckel aufstossen kann. In der Regel steht das Öffnungsmittel in Bezug auf einen Ansatzbereich des gelenkigen Verbindungsabschnitts nach oben, d.h. in Richtung Behälterdeckel, über.  In some embodiments, the container cover may be a multi-flap container lid and the upper edge of the container wall may form the opening means. This can for example be arranged and configured such that it can burst the multi-flap container lid. As a rule, the opening means projects upwards with respect to a shoulder region of the articulated connection section, i. in the direction of the container lid, over.
Ein solcher Behälterdeckel kann einen peripheren Befestigungsrand und mehrere über jeweils ein Scharnier mit dem Befestigungsrand verbundene Klappen aufweisen, wobei die Verschiebung des Öffnungsmittels in Richtung Behälterdeckel eine Auslenkung der Kappen um das jeweilige Scharnier bewirkt.  Such a container lid may have a peripheral fastening edge and a plurality of flaps connected to the fastening edge via a respective hinge, the displacement of the opening means in the direction of the container lid causing a deflection of the caps around the respective hinge.
Eine Betätigung des Kunststoffbehälters bewirkt ein Ausschwenken der Klappen, wobei sich der Behälterdeckel mittig zu öffnen beginnt. Die Klappen selber wirken dabei wie Rampen, welche das Substrat mittig in den Mischbehälter abgeben.  An actuation of the plastic container causes a swinging out of the flaps, wherein the container lid begins to open in the middle. The flaps themselves act as ramps, which deliver the substrate in the center of the mixing container.
Ein solcher Behälterdeckel mit Klappen ist in der Schweizer Patentanmeldung mit Titel „Kapsel mit integrierter Abgabeeinrichtung" vom selben Anmelder und mit demselben Anmeldedatum beschrieben, deren Inhalt hiermit in diese Anmeldung aufgenommen wird.  Such a container lid with flaps is described in the Swiss patent application entitled "capsule with integrated dispenser" by the same applicant and with the same filing date, the content of which is hereby incorporated into this application.
In einigen Ausführungsformen können die mehreren Klappen durch Schlitze im Behälterdeckel resp. Schlitze in der Deckfläche des Behälterdeckels ausgebildet sein, welche mehrere Sektoren des Behälterdeckels ausbilden. Die Sektoren können spitz zulaufende Sektoren sein, deren Spitzen sich an der Längsachse des Kunststoffbehälters treffen. Bevorzugt sind es gleichmässige resp. gleichförmige Kreissektoren, so dass eine plane Kreisfläche des Behälterdeckels in mindestens drei gleiche Kreissektoren aufgeteilt ist. Dabei öffnet sich der Behälterdeckel von der Mitte her und garantiert so eine kontrollierte Abgabe des Substrats. Zwischen den Klappen können die Schlitze überbrückende Stege vorhanden sein, welche Sollbruchstellen ausbilden. In some embodiments, the plurality of flaps through slots in the container lid, respectively. Slots may be formed in the top surface of the container lid, which form a plurality of sectors of the container lid. The sectors may be tapered sectors whose tips meet at the longitudinal axis of the plastic container. Preferably, it is uniform resp. uniform circular sectors, so that a flat circular surface of the container lid is divided into at least three equal circular sectors. This opens the container lid from the middle, thus guaranteeing a controlled release of the substrate. Between the flaps, the bridges bridging webs may be present, which form predetermined breaking points.
In einigen Ausführungsformen kann das Scharnier derart ausgebildet sein, dass im offenen Zustand des Behälterdeckels eine Rückstellkraft auf die Klappe wirkt. Das Scharnier kann beispielsweise in der Form eines Bogens, insbesondere eines Kreisbogens, ausgebildet sein. Dabei wirkt eine Rückstellkraft auf die ausgeschwenkte, offene Klappe und nach dem Zurückziehen des Öffnungsmittels bewegt sich die Klappe in die Geschlossenstellung zurück. Die Kapsel kann nun sauber vom Mischbehälter entfernt werden.  In some embodiments, the hinge may be configured such that in the open state of the container lid, a restoring force acts on the flap. The hinge may for example be in the form of an arc, in particular a circular arc. In this case, a restoring force acts on the pivoted, open flap and after retraction of the opening means, the flap moves back into the closed position. The capsule can now be removed cleanly from the mixing container.
In einigen Ausführungsformen kann das Öffnungmittel, welches bevorzugt durch die obere Kante der Behälterwand ausgebildet ist, eine vordere Anschlagsfläche aufweisen, welche bei Betätigung des Kunststoffbehälters gegen die mehreren Klappen drückt und ein Ausschwenken dieser Klappen bewirkt.  In some embodiments, the opening means, which is preferably formed by the upper edge of the container wall, having a front stop surface, which presses upon actuation of the plastic container against the plurality of flaps and causes swinging of these valves.
Dabei kann die Anschlagsfläche auch aus mehreren (Teil-)Anschlagsflächen ausgebildet sein. Bevorzugt ist die Anschlagsfläche ringförmig ausgestaltet oder die mehrere (Teil-)Anschlagsflächen sind ringförmig angeordnet. Dabei ist in der Regel jede Anschlagsfläche in Bezug auf ein jeweiliges Scharnier radial nach innen versetzt angeordnet.  In this case, the stop surface may also be formed from a plurality of (partial) stop surfaces. Preferably, the abutment surface is configured annular or the plurality of (partial) abutment surfaces are arranged in a ring. As a rule, each abutment surface is arranged offset radially inwards relative to a respective hinge.
D.h. eine ringförmige Anschlagsfläche ist in Bezug auf die mehreren Filmscharniere radial nach innen versetzt angeordnet oder die mehreren ringförmig angeordneten Anschlagsflächen sind in Bezug auf die mehreren Filmscharniere jeweils radial nach innen versetzt angeordnet.  That an annular abutment surface is offset radially inwardly with respect to the plurality of film hinges, or the plurality of annularly disposed abutment surfaces are offset radially inwardly with respect to the plurality of film hinges, respectively.
Mit anderen Worten ist der Durchmesser einer ringförmigen Anschlagsfläche oder mehrere ringförmig angeordneter Anschlagsflächen geringer als der Abstand der Scharniere vom Mittelpunkt der Ringform. Bevorzugt nur geringfügig, so dass die Anschlagsfläche möglichst nahe am Filmscharnier auf die Klappe auftrifft, aber noch genügend weit davon entfernt, damit eine genügend grosse Hebelwirkung zum Aufdrücken der Klappen vorhanden ist. Auf diese Weise können die Klappen auch mittels einer geringen Bewegung des Öffnungsmittels fast vollständig, d.h. bis nahezu 90° in Bezug auf die plane Ausgangsposition ausgeschwenkt werden. Idealerweise beträgt die Ausschwenkung mindestens 60° bei einem vollständig nach vorne bewegten Öffnungsmittel. In other words, the diameter of an annular abutment surface or a plurality of annularly arranged stop surfaces is less than the distance of the hinges from the center of the ring shape. Preferably only slightly so that the stop surface as close to the hinge on the flap hits, but still sufficiently far away, so that a sufficiently large leverage for pressing the flaps is present. In this way, the flaps can also almost completely by means of a small movement of the opening means, that is, to almost 90 ° with respect to the plane starting position are swung. Ideally, the swinging is at least 60 ° with a fully forward moving opening means.
In einigen Ausführungsformen kann die Behälterabdeckung eine Siegelfolie sein und das Öffnungsmittel als Schneidkante ausgebildet sein. Die Siegelfolie kann dabei an einem nach aussen gerichteten Flansch der oberen Umrandung befestigt sein. Die obere Umrandung oder der Flansch kann eine Abstützfläche aufweisen, mit welcher der Kunststoffbehälter zur Bewirkung der Verschiebung über eine Mischbehälteröffnung eines Mischbehälters abgestützt wird.  In some embodiments, the container cover may be a sealing foil and the opening means may be formed as a cutting edge. The sealing film can be attached to an outwardly directed flange of the upper border. The upper rim or flange may have a support surface with which the plastic container is supported for effecting the displacement via a mixing container opening of a mixing container.
In einigen Ausführungsformen kann die obere Umrandung eine peripher Schürze mit einem Gewinde, bevorzugt eine Innengewinde, aufweisen, mit welchem der Kunststoffbehälter auf einen Mischbehälter festschraubbar ist. In some embodiments, the upper border may have a peripheral apron with a thread, preferably an internal thread, with which the plastic container is festschraubbar on a mixing container.
In einigen Ausführungsformen kann das Öffnungsmittel ein im Innenraum angeordneter Durchstosser sein, welcher gegenüber der Behälterwand oder dem Behälterboden abgestützt ist. In some embodiments, the opening means may be an internally located piercer which is supported against the container wall or the container bottom.

Der Kunststoffbehälter umfasst eine Behälterkörper 1 und eine Behälterabdeckung 2 (in Fig. 1 und 2 teilweise geschnitten dargestellt). Der Behälterkörper 1 umfasst eine Behälterwand 3 mit einem Behälterboden 4 am unteren Ende und einer Behälteröffnung 5 am oberen Ende. Die Behälterwand 3 weist eine im Wesentlichen konische Form auf. Am oberen Ende umfasst die Behälterwand weiter eine peripher umlaufende, obere Umrandung 6. In der gezeigt Ausführungsform ist die Umrandung 6 als eine sich parallel zur Behälterwand 3 erstreckende Wand 61 ausgebildet, welche beispielsweise eine Höhe von 5 bis 15 mm aufweist. Die Umrandung 6 umfasst am oberen Ende der Wand 61 einen radial nach aussen gerichteten Flansch 62 mit einer peripheren, nach unten gerichteten Schürze 63 zur Verstärkung auf. Figures 1 to 3 show a plastic container with integrated opening mechanism. Fig. 4 shows a section of the plastic container in an open position and a closed position. The plastic container comprises a container body 1 and a container cover 2 (shown partially cut in Figs. 1 and 2). The container body 1 comprises a container wall 3 with a container bottom 4 at the lower end and a container opening 5 at the upper end. The container wall 3 has a substantially conical shape. At the upper end, the container wall further comprises a peripherally encircling, upper border 6. In the embodiment shown, the border 6 is formed as a wall 61 extending parallel to the container wall 3, which for example has a height of 5 to 15 mm. The skirt 6 comprises at the upper end of the wall 61 a radially outwardly directed flange 62 with a peripheral, downwardly directed skirt 63 for reinforcement.
Am unteren Ende der Wand 61 ist die Umrandung 6 über einen gelenkigen Verbindungsabschnitt 8 mit der Behälterwand 3 verbunden. Der gelenkige Verbindungsabschnitt 8 weist in der gezeigten Ausführungsform einen Schlaufen- oder U-förmigen Querschnitt auf. Die Behälterwand 3 und die Umrandung 6 weisen im Wesentlichen dieselbe Wandstärke auf. Der Verbindungsabschnitt 8 ist dünner als die Behälterwand 3 resp. die Umrandung 6 ausgestaltet. Der Verbindungsabschnitt 8 ist derart flexibel, dass die Umrandung 6 relative zur Behälterwand 3 von einer Geschlossenstellung (Fig. 4(a)) in eine Offenstellung (Fig. 4(b)) bewegbar ist. Oberhalb der Ansatzstelle 81 der gelenkigen Verbindung 8 an der Behälterwand 3 erstreckt sich die Behälterwand 3 weiter nach oben und bildet an deren oberen Kante 7 die Öffnungsmittel 9 aus. Die obere Kante 7 liegt unterhalb einer durch den Flansch 62 definierten Ebene. At the lower end of the wall 61, the border 6 is connected to the container wall 3 via an articulated connection section 8. The articulated connecting portion 8 has in the embodiment shown on a loop or U-shaped cross-section. The container wall 3 and the border 6 have substantially the same wall thickness. The connecting portion 8 is thinner than the container wall 3, respectively. designed the border 6. The connecting section 8 is so flexible that the border 6 is movable relative to the container wall 3 from a closed position (FIG. 4 (a)) into an open position (FIG. 4 (b)). Above the attachment point 81 of the articulated connection 8 on the container wall 3, the container wall 3 further extends upwards and forms at its upper edge 7 the opening means 9 off. The upper edge 7 lies below a plane defined by the flange 62.
Der Schlaufen- oder U-förmige, gelenkige Verbindungsabschnitt 8 ist mit den beiden Endbereichen an der Behälterwand 3 resp. der oberen Umrandung 6 verbunden. In der Geschlossenstellung befinden sich die beiden Enden im Wesentliche auf derselben Höhe. In der Offenstellung sind sie voneinander wegbewegt und der gelenkige Verbindungsabschnitt 87 ist gestreckt.  The loop or U-shaped, articulated connection portion 8 is with the two end portions of the container wall 3, respectively. the upper border 6 connected. In the closed position, the two ends are essentially at the same height. In the open position, they are moved away from each other and the articulated connection portion 87 is stretched.
In der gezeigten Ausführungsform ist die Behälterabdeckung 2 ein Behälterdeckel 2' mit mehreren Klappen 24 zum Abdecken der Behälteröffnung 5 und weist eine peripheren Befestigungsrand 21 auf. Ein solcher Behälterdeckel 2' ist in der Schweizer Patentanmeldung mit Titel „Kapsel mit integrierter Abgabeeinrichtung" vom selben Anmelder und mit demselben Anmeldedatum beschrieben, deren Inhalt hiermit in diese Anmeldung aufgenommen wird. Der Behälterdeckel 2' kann mit dem Befestigungsrand 21 direkt der Umrandung 6 befestigt sein, oder - wie in der gezeigten Ausführungsform - am peripheren Befestigungsrand 21 eine umlaufende, nach unten gerichtete Schürze 22 mit einer an deren Aussenfläche angeordneten, umlaufenden Wulst 23 aufweisen. Zur Befestigung des Behälterdeckels 2' rastet die umlaufende Wulst 23 in einer an der Innenfläche der Wand 61 der Umrandung 6 angeordneten, komplementären Nut 64 ein.  In the illustrated embodiment, the container cover 2 is a container lid 2 'with a plurality of flaps 24 for covering the container opening 5 and has a peripheral attachment edge 21. Such a container lid 2 'is described in the Swiss patent application entitled "Capsule with integrated dispensing device" by the same applicant and with the same filing date, the contents of which are hereby incorporated into this application The container lid 2' can be fastened directly to the border 6 with the fastening edge 21 be, or - as in the embodiment shown - on the peripheral mounting edge 21 has a circumferential, downwardly directed skirt 22 with a circumferential bead 23 disposed on its outer surface the wall 61 of the border 6 arranged, complementary groove 64 a.
In der gezeigten Ausführungsform des Behälterdeckels 2' sind mittels durchgehenden Schlitzen 25 in der Deckelfläche vier Klappen 24 in der Form von gleichförmigen Kreissektoren ausgebildet. Diese Klappen 24 sind jeweils über ein Scharnier 26, vorzugsweise ein Filmscharnier, mit dem Befestigungsrand 21 des Behälterdeckels 2' verbunden. Zwischen den Klappen 24 können die Schlitze 25 überbrückende Haltestege vorhanden sein, welche Sollbruchstellen ausbilden. Anstelle der Schlitze sind auch Sollbruchstellen in Form von Dünnstellen möglich.  In the illustrated embodiment of the container lid 2 'are formed by means of through slots 25 in the lid surface four flaps 24 in the form of uniform circular sectors. These flaps 24 are each connected via a hinge 26, preferably a film hinge, with the fastening edge 21 of the container lid 2 '. Between the flaps 24, the slots 25 bridging retaining webs may be present, which form predetermined breaking points. Instead of the slots and predetermined breaking points in the form of thin bodies are possible.
Fig. 4 ist eine Detailansicht des gelenkigen Verbindungabschnitts 7 unter (a) in einer Geschlossenstellung und unter (b) in einer Offenstellung gezeigt. In der Geschlossenstellung befindet sich die Umrandung 6 in Bezug auf die Behälterwand 3 resp. die Öffnungsmittel 9 in einer oberen Position, in welcher der gelenkige Verbindungsabschnitt 8 einen Schlaufen- oder U-förmigen Querschnitt aufweist und die obere Kante 7 der Behälterwand 3 resp. der Öffnungsmittel 9 sich unterhalb einer durch den Flansch definierten Fläche befindet. Dabei ist das Öffnungsmittel 9 vom Behälterdeckel 2' überdeckt. Fig. 4 is a detail view of the articulated connection portion 7 under (a) shown in a closed position and under (b) in an open position. In the closed position, the border 6 is in relation to the Container wall 3 resp. the opening means 9 in an upper position in which the articulated connecting portion 8 has a loop or U-shaped cross-section and the upper edge 7 of the container wall 3, respectively. the opening means 9 is located below a surface defined by the flange. In this case, the opening means 9 is covered by the container lid 2 '.
Um den Behälterdeckel 2' zu öffnen, wird die Umrandung 6, an welcher der Behälterdeckel 2' befestigt ist, nach unten entlang der Behälterachse A in Richtung Behälterboden 4 geschoben. Dies kann beispielsweise geschehen, indem der Kunststoffbehälter mit dem Flansch 62, welcher gleichzeitig eine Abstützfläche 65 ausbildet, auf den Hals eines Mischbehälters gedrückt. Dabei Verschieben sich die Öffnungsmittel 9 relativ zum Behälterdeckel 2' und drücken mit der oberen Kante 7 dessen Klappen 24 auf. In der Offenstellung stehen die Öffnungsmittel 9 über den Flansch 62 der Umrandung 6 vor. Der gelenkige Verbindungsabschnitt 8, welcher flexibel ausgestaltet ist, wird dabei gestreckt (vgl. Fig. 4(b)). Die maximale Verschiebung entspricht dabei in etwa der Länge des Verbindungsabschnitts 8 resp. zweimal der Länge eines Schenkels der U-Form.  In order to open the container lid 2 ', the border 6, to which the container lid 2' is fastened, is pushed downwards along the container axis A in the direction of the container bottom 4. This can be done, for example, by pressing the plastic container with the flange 62, which simultaneously forms a support surface 65, onto the neck of a mixing container. In this case, the opening means 9 move relative to the container lid 2 'and press with the upper edge 7 of the flaps 24. In the open position, the opening means 9 project beyond the flange 62 of the border 6. The articulated connection section 8, which is designed to be flexible, is thereby stretched (compare Fig. 4 (b)). The maximum displacement corresponds approximately to the length of the connecting portion 8, respectively. twice the length of a leg of the U-shape.
Die Filmscharniere 26 am Behälterdeckel 2', welche jeweils die Klappen 24 am Behälterdeckel 2' halten, können bogenförmig ausgestaltet sein (vgl. Fig. 1). Dies führt dazu, dass auf die ausgeschwenkte Klappe 24, d.h. in der Offenstellung, eine Rückstellkraft auf die Klappe 24 wirkt. Wird das Öffnungsmittel 9 wieder zurückgezogen, schliessen sich auch die Klappen 24 zumindest teilweise.  The film hinges 26 on the container lid 2 ', which each hold the flaps 24 on the container lid 2', can be configured arcuate (see Fig. 1). This results in that the swung-flap 24, i. in the open position, a restoring force acts on the flap 24. If the opening means 9 withdrawn again, the flaps 24 close at least partially.
Der Behälterboden 4 ist in der gezeigten Ausführungsform nach aussen gewölbt. Am unteren Ende der Behälterwand 3 ist eine den Behälterboden 4 überragende Schürze 31 ausgebildet.  The container bottom 4 is curved in the embodiment shown to the outside. At the lower end of the container wall 3 a the container bottom 4 protruding apron 31 is formed.
In Fig. 5 ist der Kunststoffbehälter aus Fig. 1 mit teilweise geöffnetem Behälterdeckel 2' dargestellt. Dabei sind die Klappen 24 um die Filmscharniere 26 nach aussen geschwenkt.  In Fig. 5, the plastic container of Fig. 1 with partially opened container lid 2 'is shown. The flaps 24 are pivoted outwardly about the film hinges 26.
Fig. 6 zeigt eine Detailansicht eines Kunststoffbehälters mit einer Siegelfolie 2" als Behälterabdeckung 2. Die Siegelfolie 2" ist an der oberen Umrandung 6 befestigt, z.B. indem sie auf den Flansch der Umrandung 6 geschweisst ist. Das Öffnungsmittel 9 kann als Schneidkante ausgebildet sein, z.B. indem die obere Kante 7 des Behälterkörpers 1 resp. der Behälterwand 3 die Schneidkante ausbildet. Eine relative Verschiebung der Schneidkante von der Geschlossenstellung des Kunststoffbehälters in seine Offenstellung bewirkt ein Durchschneiden der Siegelfolie 2". 6 shows a detailed view of a plastic container with a sealing film 2 "as a container cover 2. The sealing film 2" is fastened to the upper border 6, for example by being welded to the flange of the border 6. The opening means 9 may be formed as a cutting edge, for example by the upper edge 7 of the container body 1, respectively. the container wall 3 forms the cutting edge. A relative displacement of the cutting edge of the closed position of the plastic container in its open position causes a cutting through the sealing film 2 ".
Fig. 7 und Fig. 8 zeigen ebenfalls einen Kunststoffbehälter mit einer Siegelfolie 2" in einer perspektivischen Ansicht und in einer Detailansicht, wobei in Fig. 7 die Siegelfolie 2" nicht dargestellt ist. Im Unterschied zum Kunststoffbehälter aus Fig. 6 ist das Öffnungsmittel 9 mit mindestens einem Durchstechmittel 10 versehen. Das Öffnungsmittel 9 ist derart ausgebildet, dass es mit der Behälterwand 3 wirkverbunden ist. Eine relative Verschiebung der der Durchstechmittel 10 von der Geschlossenstellung des Kunststoffbehälters in seine Offenstellung bewirkt ein Durchstechen der Siegelfolie 2".  FIGS. 7 and 8 likewise show a plastic container with a sealing film 2 "in a perspective view and in a detailed view, wherein in FIG. 7 the sealing film 2" is not shown. In contrast to the plastic container from FIG. 6, the opening means 9 is provided with at least one piercing means 10. The opening means 9 is formed such that it is operatively connected to the container wall 3. A relative displacement of the puncture means 10 from the closed position of the plastic container into its open position causes puncture of the sealing foil 2 ".
In der gezeigten Ausführungsform liegt das Öffnungmittel 9 auf der oberen Kante 7 der Behälterwand 3 auf. Es kann auch an der Behälterwand 3 z.B. mittels Rastmittel befestigt sein.  In the embodiment shown, the opening means 9 rests on the upper edge 7 of the container wall 3. It may also be attached to the container wall 3 e.g. be fastened by means of locking means.
Das Öffnungmittel 9 kann beispielsweise in Form einer Filterplatte mit Filteröffnungen 11 ausgebildet sein. Die Filteröffnungen können mit einem Filterpapier abgedeckt sein.  The opening means 9 may be formed, for example in the form of a filter plate with filter openings 11. The filter openings can be covered with a filter paper.
