Description

KunststofjNerschluß mit integrierter Ausgießhilfe Plastic closure with integrated pouring aid
Beschreibungdescription
Die Erfindung betrifft einen KunststoffVerschluß gemäß dem Oberbegriff des Patentanspruchs 1.The invention relates to a plastic closure according to the preamble of claim 1.
Bekannt sind Kunststofrverschlüsse für die unterschiedlichsten Anwendungen, z.B. für die Verpackung von Lebensmitteln oder von Chemikalien. Alle Kunststofrverschlüsse bestehen mindestens aus einem Teil mit Deckelfunktion und einem Basisteil, das mit dem Behältnis verbunden ist und im verschlossenen Zustand mit dem Deckelteil in formschlüssigem Eingriff steht. Je nach dem, ob der Deckel geschraubt oder geklappt wird, ist der Kuriststofrverschluß ein- oder mehrteilig ausgeführt.Plastic closures are known for a wide variety of applications, e.g. for packaging food or chemicals. All plastic closures consist of at least one part with a lid function and a base part which is connected to the container and is in positive engagement with the lid part in the closed state. Depending on whether the lid is screwed or folded, the Kuriststoffrloß is made of one or more parts.
Im wesentlichen gibt es Verschlüsse mit runder Grundform und Verschlüsse mit rechteckiger Grundform. Die Verschlüsse mit runder Grundform finden sich als Dreh- oder Klappverschluß vor allem an Flaschen oder kanisterartigen Behältern oder als Drehverschluß auch an den bekannten quaderförmigen Behältnissen für Milch, Säfte etc.. Verschlüsse mit runder Grundform, insbesondere als Drehverschluß, weisen immer eine nicht unerhebliche Höhe auf und sind daher z.B. für die erwähnten quaderförmigen Behältnisse ungeeignet, da dadurch deren Stapelfähigkeit gemindert wird.There are essentially closures with a round basic shape and closures with a rectangular basic shape. The closures with a round basic shape can be found as a twist-off or hinged closure, particularly on bottles or canister-like containers, or as a twist-off closure also on the known rectangular containers for milk, juices, etc. Closures with a round basic shape, in particular as a twist-off closure, always have a not inconsiderable height on and are therefore, for example unsuitable for the above-mentioned cuboid containers, since this reduces their stackability.
Insbesondere für quaderförmige Behältnisse werden daher normalerweise Verschlüsse mit rechteckiger Grundfläche verwendet. Diese sind im allgemeinen als Klapp- oder Einrastverschluß ausgebildet und können auf diese Weise sehr flach gehalten werden, so daß die quaderförmigen Behältnisse weiterhin praktisch uneingeschränkt stapelbar sind.Seals with a rectangular base are therefore normally used, in particular for rectangular containers. These are generally designed as a snap or snap lock and can be used on them Be kept very flat, so that the cuboid containers are still practically unlimited stackable.
Ein zusätzlicher Bestandteil eines Kunststoflverschlusses, der vor allem für die Verpackung von Lebensmitteln von Bedeutung ist, ist das sogenannte Garantiesiegel, das beim allerersten Öffnen des Verschlusses gebrochen wird und somit dem Verbraucher als Zeichen dafür dient, ob der Verschluß schon einmal geöffnet worden ist.An additional component of a plastic closure, which is particularly important for the packaging of food, is the so-called guarantee seal, which is broken when the closure is opened for the first time and thus serves as a sign for the consumer whether the closure has already been opened.
Diese Garantiesiegel können ganz unterschiedlich ausgeformt sein. Bei Drehverschlüssen findet sich oft ein Ring um das Basisteil, das bis zum ersten Aufdrehen mit dem Deckel verbunden ist. Eine weitere Möglichkeit besteht darin, das Garantiesiegel in der zentralen Öffnung des Verschlusses anzuordnen und mit einer Handhabe zu versehen, so daß das Garantiesiegel vor dem ersten Gießen oder Schütten durch Herausziehen entfernt werden kann, um die Öffnung freizugeben.These guarantee seals can take many different forms. In the case of twist locks, there is often a ring around the base part, which is connected to the lid until the first opening. Another possibility is to place the guarantee seal in the central opening of the closure and to provide it with a handle so that the guarantee seal can be removed by pulling out before the first pouring or pouring in order to expose the opening.
Allen diesen Kunststoffverschlüssen ist gemeinsam, daß sie gerade bei Flüssigkeiten ein bestenfalls mäßiges Gießverhalten aufweisen. Dieses ist auf die mangelnde Anpassung der Verschlußform an die Gieß- und Schüttfunktion - iriickzuführen.All these plastic closures have in common that they have a moderate pouring behavior at best, especially with liquids. This is due to the lack of adaptation of the closure shape to the pouring and pouring function.
Aus der US-Patentschrift 5 101 999 ist ein Flachdeckel bekannt, der in Spritzgußtechnik einteilig ausgeführt wurde. Er umfaßt ein Basisteil mit zentraler Öffnung, die durch einen umlaufenden Steg markiert ist, einen klappbar befestigten Deckel und ein Garantiesiegel, das in der zentralen Öffnung angeordnet ist. Dieser Flachdeckel zeichnet sich durch mehrere Besonderheiten aus. Der umlaufende Steg ist an einem Ende zu einer Ausgußtülle geformt. Das Garantiesiegel ist derart ausgeführt, daß es heruntergedrückt werden kann und somit das Behältnis öffnet. Es ist am gleichen Ende des Basisteils wie der Deckel klappbar befestigt und am anderen Ende über einen dünnen Steg gesichert, der für das erste Öffnen durchbrochen werden muß. In der Verbindung zum Basisteil ist ein Belüftungsloch angebracht, das zusätzlich zur Ausgußtülle das Gieß verhalten verbessern soll. Nachteilig wirkt sich aus, daß das Garantiesiegel nur schwer einzudrücken ist. Außerdem sind durch die komplexe Gestalt des Flachdeckels der Herstellungsaufwand und damit auch die Kosten unverhältnismäßig hoch.A flat cover is known from US Pat. No. 5,101,999, which was made in one piece using injection molding technology. It comprises a base part with a central opening, which is marked by a circumferential web, a hinged lid and a guarantee seal, which is arranged in the central opening. This flat lid is characterized by several special features. The peripheral web is shaped at one end into a pouring spout. The guarantee seal is designed in such a way that it can be pressed down and thus opens the container. It is hinged to the same end of the base part as the lid and to the other Secured at the end via a thin bridge which must be broken through for the first opening. In the connection to the base part there is a ventilation hole, which should improve the casting behavior in addition to the pouring spout. The disadvantage is that the guarantee seal is difficult to impress. In addition, due to the complex shape of the flat cover, the manufacturing effort and thus the costs are disproportionately high.
Der Erfindung liegt die Aufgabe zugrunde, einen Kunststoffverschluß zu finden, der trotz verbesserten Gießverhaltens möglichst einfach strukturiert ist, um zum Zwecke der Massenproduktion die Stückkosten minimal zu halten.The invention has for its object to find a plastic closure that is structured as simple as possible despite improved casting behavior in order to keep unit costs to a minimum for the purpose of mass production.
Erfindungsgemäß wird die Aufgabe durch einen Kunststoffverschluß mit den Merkmalen des Anspruchs 1 gelöst. Es ist bei einem gattungsgemäßen Kunststoffverschluß vorgesehen, daß das Garantiesiegel nach dem Aufklappen rückseitig als Ausgießhilfe ausgebildet ist.According to the invention the object is achieved by a plastic closure with the features of claim 1. It is provided in a generic plastic closure that the guarantee seal is formed on the back as a pouring aid after opening.
In den KunststofrVerschluß ist also über das integrierte Garantiesiegel gleichermaßen eine Ausgießhilfe integriert. Das Garantiesiegel ist im Auslieferungszustand zunächst an Reißlinien mit dem Unterteil verbunden. Nach dem erstmaligen Öffnen des Verschlusses reißt das Kunststofimaterial an diesen Reißlinien auf und die Schuttoffnung wird freigegeben. Bevorzugt ist das Garantiesiegel aber mit dem Unterteil über eine Verbindung, beispielsweise ein Filmscharnier derart verbunden, daß es durch eine Schwenkbewegung mit dem Filmscharnier zum Unterteil als Drehachse aus dem Unterteil herausgeklappt werden kann. Vorzugsweise ist die als Drehachse dienende Verbindung zwischen Garantiesiegel und Unterteil unlösbar im Gegensatz zu der oder den Verbindungen, die beim erstmaligen Öffnen des Verschlusses irreversibel gelöst werden. Diese Verbindung ist an der Seite des Unterteils angeordnet, zu der hin der Inhalt des Behältnisses ausgegossen oder ausgeschüttet werden soll. Die vor dem Aufklappen des Garantiesiegels dem Behältnis zugewandte Seite des Garantiesiegels ist als Ausgießhilfe ausgestaltet. Wird das Garantiesiegel weit genug aufgeklappt, wird der Inhalt des Behältnisses über diese rückwärtige, als Ausgießhilfe gestaltete Seite des Garantiesiegels aus dem Behältnis herausgeführt.A pouring aid is also integrated into the plastic closure via the integrated guarantee seal. In the delivery state, the guarantee seal is initially connected to the lower part on tear lines. After opening the closure for the first time, the plastic material tears at these tear lines and the rubble opening is released. However, the guarantee seal is preferably connected to the lower part via a connection, for example a film hinge, in such a way that it can be swung out of the lower part as an axis of rotation by a pivoting movement with the film hinge to the lower part. The connection between the guarantee seal and the lower part, which serves as the axis of rotation, is preferably undetachable, in contrast to the connection or connections which are irreversibly released when the closure is opened for the first time. This connection is arranged on the side of the lower part to which the contents of the container are to be poured or poured out. The side of the guarantee seal facing the container before the guarantee seal is opened is designed as a pouring aid. If the guarantee seal is opened far enough, the contents of the container are removed from the container via this rear side of the guarantee seal, which is designed as a pouring aid.
Oberteil und Unterteil des Kuriststoffverschlusses können entweder über eine Anbindung miteinander verbunden sein oder auch separate Komponenten sein, die beispielsweise über eine Rastverbindung oder Schraubverbindung montiert werden.The upper part and lower part of the curative substance fastener can either be connected to one another via a connection or they can also be separate components which are mounted, for example, via a snap-in connection or screw connection.
Das Unterteil ist auf beliebige Art und Weise mit dem Behältnis verbindbar. Die Befestigungsmethode wird unter anderem vom Material des Behältnisses bestimmt. Exemplarisch seien genannt Metall- oder Kunststoffbehältnisse, an die man den Kunststoffverschluß schweißen könnte, oder auch Glas oder Kartonbehältnisse, mit denen der Kuriststoffverschluß verklebt werden könnte. Grundsätzlich ist der erfindungsgemäße Kunststoffverschluß für Behältnisse jeglichen Materials geeignet.The lower part can be connected to the container in any way. The method of attachment is determined, among other things, by the material of the container. Examples include metal or plastic containers to which the plastic closure could be welded, or glass or cardboard containers with which the curative substance closure could be glued. In principle, the plastic closure according to the invention is suitable for containers of any material.
In einer bevorzugten Ausführungsform ist an dem Garantiesiegel eine Handhabe angebracht, die das Greifen und somit das Aufklappen des Garantiesiegels erleichtert.In a preferred embodiment, a handle is attached to the guarantee seal, which facilitates gripping and thus opening the guarantee seal.
Vorzugsweise weist das Unterteil eine Aussparung auf, in die das Garantiesiegel nach dem Aufklappen hineinpaßt, so daß es zur Stabilisierung während des Ausgießens oder Ausschüttens arretiert wird.The lower part preferably has a recess into which the guarantee seal fits after being opened, so that it is locked for stabilization during pouring or pouring.
Zur weiteren Verbesserung des Gießverhaltens weist eine Ausführungsform eine seitliche Führung auf, die auf das aufgeklappte Garantiesiegel zuführt. Sie verhindert beim Ausgießen oder Ausschütten des Behältnisinhaltes ein seitliches Entweichen und gewährleistet somit eine gezielte Entnahme des Behältnisinhaltes.To further improve the casting behavior, an embodiment has a lateral guide that leads to the opened guarantee seal. It prevents the contents of the container from being poured out or poured out lateral escape and thus ensures targeted removal of the contents of the container.
Vorzugsweise ist der Kunststoffverschluß als Flachverschluß ausgebildet, d.h., daß die Höhe des Verschlusses verglichen mit den Abmessungen der Grundfläche des Verschlusses gering ist. Dadurch wird insbesondere bei quaderförmigen Behältnissen eine gute Stapelbarkeit gewährleistet.The plastic closure is preferably designed as a flat closure, i.e. the height of the closure is small compared to the dimensions of the base area of the closure. This ensures good stackability, particularly in the case of rectangular containers.
Prinzipiell kann der Kunststoffverschluß eine beliebige Grundform aufweisen, sei es rund, sei es eckig, sei es oval. Als vorteilhaft hat sich erwiesen, eine dreieckige Grundform zu wählen, bei der die Verbindung zwischen Garantiesiegel und Unterteil, die beim Aufklappen des Garantiesiegels als Drehachse dient, an der Basis des Dreiecks angeordnet ist. Beim Ausgießen oder Ausschütten des Behältnisinhaltes tritt der Inhalt durch die relativ größere Fläche an der Dreieckbasis aus, während die relativ kleinere Fläche an der Dreieckspitze als Belüftungsöffnung wirkt, durch die Luft in den sich leerenden Behälter eindringen kann. Dies verbessert insbesondere bei Flüssigkeiten das Gießverhalten.In principle, the plastic closure can have any basic shape, be it round, square or oval. It has proven to be advantageous to choose a triangular basic shape in which the connection between the guarantee seal and the lower part, which serves as the axis of rotation when the guarantee seal is opened, is arranged at the base of the triangle. When the contents of the container are poured out or poured out, the contents emerge through the relatively larger area at the triangle base, while the relatively smaller area at the top of the triangle acts as a ventilation opening through which air can penetrate into the empty container. This improves the pouring behavior, especially with liquids.
Anhand der folgenden Figuren sollen exemplarisch bevorzugte Ausfuhrungsformen des erfindungsgemäßen Kunststoffverschlusses erläutert werden.

Nachfolgend sind gleiche Teile mit denselben Bezugszeichen versehen.In the following, identical parts are provided with the same reference symbols.
Die im folgenden dargestellten Ausführungsformen basieren auf einem Kunststoffverschluß mit dreieckiger Grundform. Er ist als Flachverschluß ausgeführt, bei dem die Höhe des Verschlusses verglichen mit den Maßen der Dreiecksseiten gering ist. Oberteil 2 und Unterteil 1 sind über eine AnbindungThe embodiments shown below are based on a plastic closure with a triangular basic shape. It is designed as a flat fastener, in which the height of the fastener is low compared to the dimensions of the triangle sides. Upper part 2 and lower part 1 are connected
3 verbunden und bilden gemeinsam einen Klappverschluß, wobei sie im geschlossenen Zustand über umlaufende Stege 8 in formschlüssigem Eingriff stehen.3 connected and together form a hinged closure, wherein they are in positive engagement in the closed state via circumferential webs 8.
In Fig. 1 ist ein dreieckiger Flachverschluß im geschlossenen Zustand dargestellt. Das mit dem Unterteil 1 über die Anbindung 3 verbundene Oberteil liegt schlüssig auf dem Unterteil 1 auf.In Fig. 1 a triangular flat fastener is shown in the closed state. The upper part connected to the lower part 1 via the connection 3 lies firmly on the lower part 1.
Das Oberteil 2 des in Fig. 2 gezeigten dreieckigen Flachverschlusses ist leicht angehoben, so daß darunter das Garantiesiegel 4 zu sehen ist, das mit einer schlaufenartigen Handhabe 5 versehen ist.The upper part 2 of the triangular flat closure shown in FIG. 2 is slightly raised so that the guarantee seal 4 can be seen underneath, which is provided with a loop-like handle 5.
Klappt man wie in Fig. 3 das Oberteil 2 vollständig auf, erkennt man inmitten des Unterteils 1 das Garantiesiegel 4, das wie der gesamte Kur-ststoffverschluß im wesentlichen eine dreieckige Form hat und völlig die darunterliegende Schüttöffnung 9 (s. Fign. 4-6) verdeckt. Auf der Oberseite des GarantiesiegelsIf, as in FIG. 3, the top part 2 is completely opened, one can see the guarantee seal 4 in the middle of the bottom part 1, which, like the entire plastic closure, has essentially a triangular shape and completely the pouring opening 9 underneath (see FIGS. 4-6 ) covered. On the top of the guarantee seal
4 ist an der Dreieckspitze eine Handhabe 5 in Form einer Schlaufe angebracht.4, a handle 5 in the form of a loop is attached to the triangle tip.
Fig. 4 zeigt den dreieckigen Flachverschluß, nachdem das Garantiesiegel 4 zum erstmaligen Öffnen gebrochen worden ist. Dazu greift man die Handhabe 5 und zieht daran. Da das Garantiesiegel 4 an den an der Dreieckspitze anliegenden Dreieckseiten leicht lösbar mit dem Unterteil 1 verbunden ist, lösen sich diese Verbindungen entlang der durch Materialschwächung erzeugten Reißlinien, während die Verbindung zwischen Garantiesiegel 4 und Unterteil 1 sich nicht löst. Dort sind Garantiesiegel 4 und Unterteil 1 über ein Filmscharnier 6 verbunden. Wegen dieser Anordnung führt das Garantiesiegel 4 eine Schwenkbewegung in Pfeilrichtung um das Filmscharnier 6 aus, wenn über die Handhabe 5 am Garantiesiegel 4 gezogen wird.Fig. 4 shows the triangular flat closure after the guarantee seal 4 has been broken for the first time opening. To do this, you grab the handle 5 and pulls on it. Since the guarantee seal 4 is easily detachably connected to the lower part 1 at the triangle tips, these connections loosen along the tear lines produced by material weakening, while the connection between the guarantee seal 4 and lower part 1 does not come loose. There guarantee seal 4 and lower part 1 are connected via a film hinge 6. Because of this arrangement, the guarantee seal 4 executes a pivoting movement in the direction of the arrow around the film hinge 6 when the guarantee seal 4 is pulled over the handle 5.
In Fig. 5 ist das Garantiesiegel 4 senkrecht herausgeklappt. Dessen Rückseite ist in Form einer Ausgußtülle als Ausgießhilfe 10 ausgeformt, über die der Inhalt das Behältnis verlassen kann, wenn man dieses neigt. Der Steg 8, der im geschlossenen Zustand des Verschlusses dem formschlüssigen Verschließen mit dem Oberteil 2 dient, hat im völlig geöffneten Zustand die Funktion einer seitlichen Führung, die ein seitliches Entweichen des Behältnisinhaltes verhindert.In Fig. 5, the guarantee seal 4 is folded out vertically. Its back is shaped in the form of a pouring spout as a pouring aid 10, via which the contents can leave the container if one tilts it. The web 8, which in the closed state of the closure is used for the positive closure with the upper part 2, has the function of a lateral guide in the fully open state, which prevents the contents of the container from escaping laterally.
Fig. 6 zeigt eine weitere Ausführungsform eines dreieckigen Flachverschlusses, der sich von der in Fig. 5 dargestellten Ausführungsform darin unterscheidet, daß das Unterteil 1 eine Aussparung 7 aufweist, die im umlaufenden Steg 8, der als seitliche Führung dient, angeordnet ist. Die ausgeklappte Ausgießhilfe 10 paßt genau in die Aussparung 7 hinein und läßt sich zwischen den Kanten der Aussparung 7 einklemmen, so daß die Ausgießhilfe 10 bewegungsstabilisiert wird und somit das Gieß verhalten des Kunststoffverschlusses erhöht wird. Fig. 6 shows a further embodiment of a triangular flat fastener, which differs from the embodiment shown in Fig. 5 in that the lower part 1 has a recess 7, which is arranged in the circumferential web 8, which serves as a lateral guide. The unfolded pouring aid 10 fits exactly into the recess 7 and can be clamped between the edges of the recess 7, so that the pouring aid 10 is stabilized in terms of movement and thus the pouring behavior of the plastic closure is increased.
