Abstract

The snap connection incorporates two elements (9-17). One of the two elements forms part of the lid (2) and the other forms part of the bottom part (1). In a closed position, a lug (15) of one element abuts against a thrust surface of the second element. At least one of the elements presses the lug into a first direction by the thrust surface in order to open the container by elastic deformation. The lug is positioned on a holder (14) which has a curved top part between the lug and a reinforced neck part (12).

Description

Die Erfindung betrifft einen Kunststoffbehälter gemäss dem Oberbegriff von Anspruch 1.The invention relates to a plastic container according to the preamble of claim 1.

Behälter dieser Art werden zum Beispiel zum Transport von Gütern eingesetzt. Dabei werden hohe Anforderungen an die Stabilität der Behälter gestellt. Insbesondere sollte der Deckel sicher am Behälter befestigt werden können, so dass er sich auch bei unsorgfältiger Behandlung nicht öffnet. Bisher wurden zur Befestigung des Deckels deshalb relativ aufwendige Lösungen zum Beispiel auf der Basis von Federstahlklemmen gewählt, die umständlich zu bedienen und/oder teuer waren.Containers of this type are used, for example, for the transport of goods. There are high demands on the stability of the container. In particular, the lid should be securely attached to the container so that it does not open even with careless treatment. So far, therefore, relatively complex solutions have been selected for fastening the lid, for example on the basis of spring steel clips that were cumbersome to use and / or expensive.

In EP-A-0 168 877 wird ein Behälter beschrieben, bei welchem am Deckel Haken angeordnet sind, die durch Löcher in einer Auskragung des Bodenteils geführt werden. Dieser Behälter ist, insbesondere was die Auskragung anbetrifft, aufwendig in seiner Herstellung. Im übrigen kann er nach einmaligem Verschliessen mit normalen Mitteln praktisch nicht mehr geöffnet werden.In EP-A-0 168 877 a container is described in which hooks are arranged on the lid, which are guided through holes in a projection of the bottom part. This container is, especially as far as the projection, consuming in its production. Moreover, it can not be opened after one-time closure with normal means virtually no more.

Es stellt sich deshalb die Aufgabe, einen Behälter der eingangs genannten Art bereitzustellen, dessen Verschluss einfach aufgebaut ist und dennoch ausreichende Sicherheit gewährt.It is therefore the object to provide a container of the type mentioned, the closure is simple and yet provides sufficient security.

Diese Aufgabe wird vom Behälter gemäss Anspruch 1 erfüllt.This object is achieved by the container according to claim 1.

Wird also der Deckel des erfindungsgemässen Behälters einer Öffnungskraft ausgesetzt, ohne dass die Verschlussorgane vorher in die Offenstellung gebracht werden, so gehen die Verschlussorgane in eine Sicherungsstellung über, in der sie eine gegenüber der Öffnungskraft formfeste Verbindung bilden. Durch die Öffnungskraft kann diese Verbindung ohne irreversible Beschädigung der Verschlussorgane nicht gelöst werden.Thus, if the lid of the container according to the invention is subjected to an opening force without the closure members being brought into the open position beforehand, then the closure members move into a securing position, in which they form a connection that is dimensionally stable with respect to the opening force. By opening force, this compound can not be solved without irreversible damage to the closing organs.

Dabei können die Verschlussorgane so aufgebaut werden, dass sie in der Verschlussstellung nicht elastisch verformt sind. Dies ist von grossem Vorteil, da Verschlussorgane aus Kunststoff unter Belastung zum Kriechen neigen.In this case, the closure members can be constructed so that they are not deformed elastically in the closed position. This is of great advantage, since closure organs of plastic tend to creep under load.

Eine mechanisch sehr einfache Konstruktion wird dadurch erreicht, dass das eine Verschlussorgan eine Nase aufweist, die in der Verschlussstellung gegen eine Anschlagfläche des zweiten Organs stösst. Darunter ist nicht notwendigerweise ein dauernder Kontakt der Nase mit der Anschlagfläche zu verstehen, die Geometrie kann auch so gewählt werden, dass die Nase lediglich bei Ausübung einer leichten Öffnungskraft an die Anschlagfläche stösst. Zum Öffnen des Deckels muss die Nase gegenüber der Anschlagfläche in einer ersten Richtung fortgeschoben werden. Bei gewaltsamer Öffnung, bei der die Kräfte aus einer anderen Richtung wirken, wird die Nase in eine zweite Richtung gegenüber der Anschlagfläche versetzt. Die Verschlussorgane können dabei so ausgeformt werden, dass eine Verschiebung der Nase in die zweite Richtung zum Beispiel dazu führt, dass sich das eine Verschussorgan hakenartig über die Anschlagfläche legt.A mechanically very simple construction is achieved in that the one closure member has a nose which abuts in the closed position against a stop surface of the second member. This is not necessarily to be understood as a permanent contact of the nose with the stop surface, the geometry can also be chosen so that the nose abuts the stop surface only when exerting a slight opening force. To open the lid, the nose must be pushed away from the stop surface in a first direction. In violent opening, in which the forces act from another direction, the nose is offset in a second direction relative to the stop surface. The closure members can be formed so that a displacement of the nose in the second direction, for example, causes the one Verschussorgan lays like a hook over the stop surface.

Die Anschlagfläche wird von einem unteren Rand einer im Deckel angeordneten Öffnung gebildet, was herstellungstechnisch einfach zu realisieren ist.The stop surface is formed by a lower edge of an opening arranged in the lid, which is easy to manufacture.

Der Grundaufbau eines erfindungsgemässen Behälters ist aus Fig. 1 ersichtlich. Bei dem hier gezeigten Ausführungsbeispiel handelt es sich um einen im Spritzgussverfahren hergestellten Kunststoffbehälter von etwa zehn Litern Inhalt.The basic structure of a container according to the invention is made Fig. 1 seen. In the embodiment shown here is an injection-molded plastic container of about ten liters content.

Der Behälter ist zweiteilig aufgebaut und umfasst einen Unterteil 1 und einen Deckel 2. Der obere Randbereich 3 des Unterteils 1 ist zweiwandig verstärkt. Wie in Fig. 2 dargestellt, greift die innere Wand 4 des Randbereichs 3 in eine umlaufende Nut 5 des Dekkels 2 und verhindert eine seitliche Verschiebung des Deckels 2 gegenüber dem Unterteil 1. Die Aussenwand 6 des Randbereichs 3 ist bündig zum vertikalen Deckelrand 7.The container is constructed in two parts and comprises a lower part 1 and a cover 2. The upper edge region 3 of the lower part 1 is reinforced two-walled. As in Fig. 2 shown, engages the inner wall 4 of the edge portion 3 in a circumferential groove 5 of the lid 2 and prevents lateral displacement of the lid 2 relative to the lower part 1. The outer wall 6 of the edge portion 3 is flush with the vertical lid edge. 7

Zur lösbaren Befestigung des Deckels 2 am Unterteil 1 sind im vorliegenden Beispiel an gegenüberliegenden Behälterseiten zwei Schnappmechanismen vorgesehen, von denen in den Figuren 1 und 2 nur einer zu sehen ist. Je nach Grösse und Form des Behälters kann die Zahl der Schnappmechanismen jedoch auch grösser oder kleiner sein.For releasably securing the cover 2 on the lower part 1, two snap mechanisms are provided in the present example on opposite sides of the container, of which in the Figures 1 and 2 only one can be seen. However, depending on the size and shape of the container, the number of snap mechanisms may be larger or smaller.

Der Aufbau des Schnappmechanismus wird im folgenden anhand der Figuren 2 bis 5 erläutert.The structure of the snap mechanism is described below with reference to FIGS. 2 to 5 explained.

Der Schnappmechanismus besteht aus zwei Verschlussorganen, von denen das eine am Deckel 2 und das andere am Unterteil 1 ausgeformt ist. Am Unterteil 1 umfasst das Verschlussorgan eine Zunge 12, 14, 15, am Deckel eine Öffnung 11 und einen Griff 9.The snap mechanism consists of two closure members, one of which is formed on the lid 2 and the other on the lower part 1. On the lower part 1, the closure member comprises a tongue 12, 14, 15, on the lid an opening 11 and a handle. 9

Die Zunge besitzt einen Hals 12, der von einen zurückversetzten Bereich der vertikalen Aussenwand 6 des Randbereichs 3 gebildet wird. Der Hals 12 ist mit zwei Stegen 13 verstärkt. Im unteren Bereich des Halses 12 erstrecken sich diese Stege bis zur Innenwand 4, nach oben sind sie verjüngt. An seinem oberen Ende geht der Hals 12 in einen Kopfbereich 14 über, der einen bogenförmigen Übergang zu einer Zunge 15 bildet. An seiner Innenseite ist der Kopf 14 durch drei Stege 16 verstärkt.The tongue has a neck 12 which is formed by a recessed area of the vertical outer wall 6 of the edge region 3. The neck 12 is reinforced with two webs 13. In the lower region of the neck 12, these webs extend to the inner wall 4, they are tapered upwards. At its upper end, the neck 12 merges into a head region 14, which forms an arcuate transition to a tongue 15. On its inside, the head 14 is reinforced by three webs 16.

Die Nase 15 liegt bündig zur Aussenseite des Deckel-Randbereichs. Damit wird eine unbeabsichtigte Betätigung oder ein Verhaken mit anderen Gegenständen vermieden.The nose 15 is flush with the outside of the lid edge area. This avoids accidental operation or snagging with other objects.

Das untere Ende der Nase 15 berührt den unteren Rand der Öffnung 11. Dieser Rand bildet zusammen mit einem Steg 17 eine Anschlagfläche 18.The lower end of the nose 15 touches the lower edge of the opening 11. This edge, together with a web 17, a stop surface 18th

In den Figuren 1 bis 5 wird der Schnappmechanismus in seiner Verschlussstellung gezeigt. In dieser Stellung wirkt er einer Öffnung des Deckels entgegen. Wird auf den Deckel 2 eine nicht allzu grosse Zugkraft K1 ausgeübt (vgl. Fig. 4), so wird diese über die Anschlagfläche 18 auf die Nase 16 und somit auf den Unterteil 1 übertragen.In the FIGS. 1 to 5 the snap mechanism is shown in its closed position. In this position he opposes an opening of the lid. If a not very great tensile force K1 is exerted on the cover 2 (cf. Fig. 4 ), this is transmitted via the stop surface 18 on the nose 16 and thus on the lower part 1.

In der Verschlussstellung sind alle Teile des Schnappmechanismus entspannt, d.h. keiner elastischen Verformung unterworfen. Dadurch wird ein Kriechen des Kunststoffs und eine bleibende Verformung der Teile verhindert.In the closed position, all parts of the snap mechanism are relaxed, i. not subject to elastic deformation. This prevents creeping of the plastic and permanent deformation of the parts.

Zum Öffnen des Deckels 2 muss der Schnappmechanismus in eine Offenstellung gebracht werden. Hierzu greift der Benutzer z. B. mit dem Zeigefinger hinter den Griff 9 und drückt mit dem Daumen auf die Zunge 15. Auf diese Weise übt er seitliche Kräfte K2 und K3 aus. Dabei verformt sich der Randbereich des Deckels 2 elastisch nach aussen. Gleichzeitig wird eine elastische Verformung der Nase 15, des Kopfbereichs 14 und des Halses 12 nach innen bewirkt. Dabei bewegt sich die Nase 15 von der Auflagerfläche 18 nach innen, so dass der Deckel frei kommt und geöffnet werden kann.To open the lid 2, the snap mechanism must be brought into an open position. For this purpose, the user z. B. with the index finger behind the handle 9 and presses with the thumb on the tongue 15. In this way it exerts lateral forces K2 and K3. In this case, the edge region of the lid 2 deforms elastically outward. At the same time an elastic deformation of the nose 15, the head portion 14 and the neck 12 is effected inwardly. In this case, the nose 15 moves from the support surface 18 inwards, so that the lid comes free and can be opened.

Zum Schliessen des Deckels 2 wird dieser einfach auf den Unterteil 1 gesetzt. Dabei drängen der Griff 9 und der Steg 17 den abgeschrägten Kopf 14 nach innen. Sobald die Nase 15 auf der Höhe der Öffnung 11 angelangt ist, federt der Kopf wieder nach aussen in die Verschlussstellung.To close the lid 2, this is simply placed on the lower part 1. In doing so, the handle 9 and the web 17 urge the bevelled head 14 inwards. Once the nose 15 has reached the height of the opening 11, the head springs back outward in the closed position.

Befindet sich der Schnappmechanismus in seiner Verschlussstellung und wird eine sehr grosse Zugkraft K1' auf den Deckel ausgeübt, so wird der Schnappmechanismus in eine Sicherungsstellung gebracht, die in Fig. 6 dargestellt ist. Dabei verformen sich der Kopfbereich 14 und die Nase 15, und die Nase 15 rutscht nach aussen von den Anschlagfläche 18 ab. Die Anschlagfläche wird etwas angehoben und vom Kopfbereich 14 hakenartig festgehalten. Dadurch wird eine weitere Aufwärtsbewegung des Deckels 2 verhindert. Der Deckel 2 könnte nur unter erheblicher Verformung oder gar Zerstörung des Schnappmechanismus weiter angehoben werden.The snap mechanism is in its closed position and a very large tensile force K1 'is exerted on the lid, the snap mechanism is brought into a securing position, the in Fig. 6 is shown. In this case, the head portion 14 and the nose 15 deform, and the nose 15 slips outwardly from the stop surface 18 from. The stop surface is raised slightly and held in a hook-like manner by the head region 14. As a result, a further upward movement of the lid 2 is prevented. The lid 2 could be raised only under considerable deformation or even destruction of the snap mechanism.

Damit sich die Nase 15 bei grösserer Kraft K1' automatisch nach aussen schiebt, ist im vorliegenden Ausführungsbeispiel die Auflagefläche 18 nach aussen etwas abgeschrägt. Ausserdem steht die Nase bereits in ihrer normalen Verschlussposition nahe der äusseren Kante der Auflagefläche 18. Weiter wird die gewünschte Verformung dadurch unterstützt, dass der gebogene Kopfbereich 14 durch die Kraft K1' zwangsläufig etwas aufgeweitet und leicht nach innen geneigt wird, so dass die Nase 15 in eine nach aussen gerichtet Stellung kommt. Der Hals 12 ist andererseits steifer ausgeführt, so dass der Kopfbereich 14 und die Nase 15 nicht als Ganzes nach innen schwenken können. Diese verschiedenen Massnahmen ergänzen sich im vorliegenden Beispiel ideal, können jedoch auch einzeln für sich eingesetzt werden, um zu bewirken, dass die Nase 15 bei grosser Kraft K1' nach vorne von der Auflagefläche 18 rutscht.So that the nose 15 automatically pushes outward with a greater force K1 ', in the present exemplary embodiment the support surface 18 is somewhat bevelled outwards. In addition, the nose is already in its normal closed position near the outer edge of the support surface 18. Further, the desired deformation is supported by the fact that the curved head portion 14 by the force K1 'inevitably slightly widened and slightly inclined inwards, so that the nose 15th comes in a directed outward position. On the other hand, the neck 12 is made stiffer so that the head portion 14 and the nose 15 can not pivot inwardly as a whole. These various measures complement each other ideally in the present example, but can also be used individually for themselves, to cause the nose 15 slips forward from the support surface 18 at great force K1 '.

Die in den Figuren gezeigte Ausführung der Erfindung ist in Spritzgusstechnik einfach herzustellen. Hierzu wurde der Hals 12 als Teil der Aussenwand 6 geformt, so dass der Bereich unter dem Kopf 14 gut zugänglich und in einem Arbeitsschritt entformbar ist. Die beiden Verschlussorgane sind einstückig am Unterteil 1 bzw. am Boden 2 ausgeformt und benötigen zu ihrer Herstellung keine weiteren Arbeitsschritte.The embodiment of the invention shown in the figures is easy to manufacture by injection molding. For this purpose, the neck 12 was formed as part of the outer wall 6, so that the area under the head 14 is easily accessible and can be demoulded in one operation. The two closure members are integrally formed on the lower part 1 and the bottom 2 and require for their production no further steps.

Durch seinen hier beschriebenen Aufbau ist der Behälter äusserst stabil. Selbst wenn er aus grösserer Höhe auf den Boden fällt, springt der Deckel nicht ab. Seitliche Deckelkräfte werden durch die Nut 5 bzw. geeignete Verstärkungsrippen auf den Unterteil 1 übertragen, während Zugkräfte sicher durch den Schnappmechanismus aufgefangen werden.By its construction described here, the container is extremely stable. Even if it falls from a greater height on the ground, the lid does not jump off. Lateral cover forces are transmitted through the groove 5 or suitable reinforcing ribs on the lower part 1, while tensile forces are reliably absorbed by the snap mechanism.
