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. Containers of this type are used for example for transporting goods. Dabei werden hohe Anforderungen an die Stabilität der Behälter gestellt. High demands are placed on the stability of the container. Insbesondere sollte der Deckel sicher am Behälter befestigt werden können, so dass er sich auch bei unsorgfältiger Behandlung nicht öffnet. In particular, the lid should be safe can be secured to the container so that it does not open even with bad treatment. 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. So far, relatively expensive solutions were selected, for example on the basis of spring steel clips for fixing the cover so that awkward to use and / or were 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. In EP-A-0 168 877 container is described in which hooks are arranged on the cover, which are led through holes in a projection of the base part. Dieser Behälter ist, insbesondere was die Auskragung anbetrifft, aufwendig in seiner Herstellung. This container is, in particular as far as the projection, expensive to manufacture. Im übrigen kann er nach einmaligem Verschliessen mit normalen Mitteln praktisch nicht mehr geöffnet werden. For the rest, it can not be opened after a single closing by normal means practical.

Es stellt sich deshalb die Aufgabe, einen Behälter der eingangs genannten Art bereitzustellen, dessen Verschluss einfach aufgebaut ist und dennoch ausreichende Sicherheit gewährt. therefore it has as its object to provide a container of the type mentioned, whose 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. Thus, if the cover of the novel container of an opening force exposed, without the closure elements are brought into the open position previously, the closure elements go over into a securing position, in which they form a opposite to the opening force dimensionally stable connection. Durch die Öffnungskraft kann diese Verbindung ohne irreversible Beschädigung der Verschlussorgane nicht gelöst werden. By opening force, this connection can not be solved without irreversible damage to the closure elements.

Dabei können die Verschlussorgane so aufgebaut werden, dass sie in der Verschlussstellung nicht elastisch verformt sind. The closure elements can be constructed so that they are not elastically deformed in the closed position. Dies ist von grossem Vorteil, da Verschlussorgane aus Kunststoff unter Belastung zum Kriechen neigen. This is of great advantage, since closure elements made 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. 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. 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. Among them is not necessarily a permanent contact of the nose with the abutment surface to understand the geometry can also be selected so that the nose abuts the stop surface merely by exercising a slight opening force. Zum Öffnen des Deckels muss die Nase gegenüber der Anschlagfläche in einer ersten Richtung fortgeschoben werden. To open the lid, the nose against the stop surface must be continuously pushed in a first direction. Bei gewaltsamer Öffnung, bei der die Kräfte aus einer anderen Richtung wirken, wird die Nase in eine zweite Richtung gegenüber der Anschlagfläche versetzt. In violent opening, in which the forces act from a different direction, the nose in a second direction is offset from the abutment surface. 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. The locking devices can thereby be formed so that a displacement of the nose in the second direction, for example, causes the Verschussorgan defining a hook-like manner on the abutment 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 cover, which is technically easy to realize production.

Weitere Vorteile und wichtige Aspekte des erfindungsgemässen Behälters ergeben sich aus der nun folgenden Beschreibung anhand der Figuren. Further advantages and important aspects of the inventive container will emerge from the following description with reference to FIGS. Dabei zeigen: They show:

  • Figur 6 einen Vertikalschnitt durch den Schnappmechanismus in seiner Sicherungsstellung. 6 shows a vertical section through the snap mechanism in its securing position.
  • Der Grundaufbau eines erfindungsgemässen Behälters ist aus Fig. 1 ersichtlich. The basic structure of an inventive container can be seen in FIG. 1. Bei dem hier gezeigten Ausführungsbeispiel handelt es sich um einen im Spritzgussverfahren hergestellten Kunststoffbehälter von etwa zehn Litern Inhalt. In the example shown here is an injection molded plastic container of about ten liters.

    Der Behälter ist zweiteilig aufgebaut und umfasst einen Unterteil 1 und einen Deckel 2. Der obere Randbereich 3 des Unterteils 1 ist zweiwandig verstärkt. The container is constructed in two parts and comprises a lower part 1 and a cover 2. The upper edge portion 3 of the lower part 1 has two walls reinforced. Wie in Fig. 2 dargestellt, greift die innere Wand 4 des Randbereichs 3 in eine umlaufende Nut 5 des Deckels 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. As shown in Fig. 2, engages the inner wall 4 of the edge portion 3 in a circumferential groove 5 of the cover 2 and prevents lateral displacement of the cover 2 relative to the bottom part 1. The external wall 6 of the edge portion 3 is flush with the vertical cover 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. For releasably securing the lid 2 on the bottom part 1, two latch mechanisms are provided in this example on opposite container sides of which in Figures 1 and 2, only one can be seen. Je nach Grösse und Form des Behälters kann die Zahl der Schnappmechanismen jedoch auch grösser oder kleiner sein. Depending on the size and shape of the container, the number of snap mechanisms may, however, be larger or smaller.

    Der Aufbau des Schnappmechanismus wird im folgenden anhand der Figuren 2 bis 5 erläutert. The structure of the snap-mechanism will be explained below with reference to Figures 2 to 5th

    Der Schnappmechanismus besteht aus zwei Verschlussorganen, von denen das eine am Deckel 2 und das andere am Unterteil 1 ausgeformt ist. The snap mechanism consists of two closure members, one of which is formed on the cover 2 and the other on the lower part 1 a. Am Unterteil 1 umfasst das Verschlussorgan eine Zunge 12, 14, 15, am Deckel eine Öffnung 11 und einen Griff 9. At the lower part 1 of the closure member on the cover comprises a tongue 12, 14, 15, 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. The tongue has a neck 12, which is formed by a recessed portion of the vertical outer wall 6 of the edge line 3. Der Hals 12 ist mit zwei Stegen 13 verstärkt. The neck 12 is reinforced with two webs. 13 Im unteren Bereich des Halses 12 erstrecken sich diese Stege bis zur Innenwand 4, nach oben sind sie verjüngt. In the lower part of the neck 12, these webs extending to the inner wall 4, they are tapered upwards. An seinem oberen Ende geht der Hals 12 in einen Kopfbereich 14 über, der einen bogenförmigen Übergang zu einer Zunge 15 bildet. At its upper end, the neck 12 passes into a head portion 14 which defines an arcuate transition to a tongue 15 °. An seiner Innenseite ist der Kopf 14 durch drei Stege 16 verstärkt. On its inside the head 14 is reinforced by three webs sixteenth

    Die Nase 15 liegt bündig zur Aussenseite des Deckel-Randbereichs. The nose 15 is flush with the outer side of the cover edge region. Damit wird eine unbeabsichtigte Betätigung oder ein Verhaken mit anderen Gegenständen vermieden. Thus accidental operation or entanglement with other objects is avoided.

    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 contacts the lower edge of the opening 11. This edge, together with a web 17 has a stop surface eighteenth

    In den Figuren 1 bis 5 wird der Schnappmechanismus in seiner Verschlussstellung gezeigt. In the figures 1 to 5, the snap mechanism is shown in its closed position. In dieser Stellung wirkt er einer Öffnung des Deckels entgegen. In this position he acts against an opening of the lid. 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. Is on the lid 2 a not too large tensile force exerted K1 (see. Fig. 4), this is thus transmitted via the stop surface 18 on the nose 16 and on the lower part 1.

    In der Verschlussstellung sind alle Teile des Schnappmechanismus entspannt, dh keiner elastischen Verformung unterworfen. In the closed position, all parts of the snap mechanism are relaxed, ie not subjected to elastic deformation. Dadurch wird ein Kriechen des Kunststoffs und eine bleibende Verformung der Teile verhindert. Characterized a plastic creep and permanent deformation of the parts is prevented.

    Zum Öffnen des Deckels 2 muss der Schnappmechanismus in eine Offenstellung gebracht werden. To open the lid 2 of the snap mechanism has to be brought into an open position. Hierzu greift der Benutzer z. To this end, the user such attacks. 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. As with the index finger behind the handle 9 and pressed with the thumb on the tongue 15. In this way, it exerts lateral forces K2 and K3. Dabei verformt sich der Randbereich des Deckels 2 elastisch nach aussen. Here, the edge area of ​​the lid 2 elastically deformed outward. Gleichzeitig wird eine elastische Verformung der Nase 15, des Kopfbereichs 14 und des Halses 12 nach innen bewirkt. At the same time, elastic deformation of the nose 15, the head portion 14 and the neck 12 is effected inside. Dabei bewegt sich die Nase 15 von der Auflagefläche 18 nach innen, so dass der Deckel frei kommt und geöffnet werden kann. In this case, the nose 15 is moved from the supporting surface 18 to the inside, so that the lid comes free and can be opened.

    Zum Schliessen des Deckels 2 wird dieser einfach auf den Unterteil 1 gesetzt. For closing the cover 2, this is simply placed on the bottom part. 1 Dabei drängen der Griff 9 und der Steg 17 den abgeschrägten Kopf 14 nach innen. In this case, the handle 9 and the web 17 urging the tapered head 14 to the inside. Sobald die Nase 15 auf der Höhe der Öffnung 11 angelangt ist, federt der Kopf wieder nach aussen in die Verschlussstellung. Once the nose 15 has arrived at the height of the opening 11, the head springs outward again 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. the latch mechanism is in its closed position and a very large tensile force K1 'applied to the lid, the latching mechanism is brought into a securing position, shown in Fig. 6. Dabei verformen sich der Kopfbereich 14 und die Nase 15, und die Nase 15 rutscht nach aussen von den Anschlagfläche 18 ab. In this case, the head portion 14 and the nose 15 deform the nose 15 and slides outwardly from the abutment surface 18 from. Die Anschlagfläche wird etwas angehoben und vom Kopfbereich 14 hakenartig festgehalten. The stop surface is slightly raised and held by the head portion 14 like a hook. Dadurch wird eine weitere Aufwärtsbewegung des Deckels 2 verhindert. Thereby a further upward movement of the lid 2 is prevented. Der Deckel 2 könnte nur unter erheblicher Verformung oder gar Zerstörung des Schnappmechanismus weiter angehoben werden. The cover 2 could be further raised only with 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. Thus, the nose 15 'automatically pushes with greater force K1 to the outside, in the present embodiment, the support surface is somewhat bevelled 18 to the outside. 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 gerichtete Stellung kommt. Furthermore, the nose is already in its normal closure position near the outer edge of the support surface 18. Further, the desired deformation is assisted by the fact is that the bent head portion 14 is expanded slightly by the force K1 'inevitably and slightly tilted inward so that the nose 15 is in an outwardly directed position. Der Hals 12 ist andererseits steifer ausgeführt, so dass der Kopfbereich 14 und die Nase 15 nicht als Ganzes nach innen schwenken können. The neck 12 is the other part stiffer, so that the head portion 14 and the nose 15 can not pivot as a whole to the inside. 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. These various measures complement each other perfectly in the present example, but may also be used individually by themselves to cause the nose 15 slides with great force K1 'to the front of the support surface eighteenth

    Die in den Figuren gezeigte Ausführung der Erfindung ist in Spritzgusstechnik einfach herzustellen. The embodiments of the invention shown in the figures, is easy to produce in injection molding technique. 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. For this purpose, the neck 12 has been formed as part of the outer wall 6, so that the region is easily accessible under the head 14 and removed from the mold in one work step. Die beiden Verschlussorgane sind einstückig am Unterteil 1 bzw. am Boden 2 ausgeformt und benötigen zu ihrer Herstellung keine weiteren Arbeitsschritte. The two closure elements are integrally formed on the bottom part 1 or on the bottom 2, and require for their preparation, no further work steps.

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

    Claims (13)

    1. A plastic container with a lower part (1) and a lid (2) as well as at least one snapping mechanism (9-18) for attaching the lid (2) to the lower part (1), wherein the snapping mechanism comprises a first and a second member (12-15; 9, 11, 17, 18),
      wherein the members are snapped into each other in a closed position and resist against an opening of the lid (2) by a nose (15) of the first member abutting against a stopping surface (18) of the second member,
      wherein for opening the lid (2) the members can be brought into an opened position by urging the nose (15) in a first direction from the stopping surface (18) by elastic deformation of at least one of the members,
      and wherein by exertion of a sufficient opening force (K1') on the lid, the nose (15) can be urged from the stopping surface (18) in a different second direction and the members can be brought from the closed position into a safety position, where they form a connection positively acting against the opening force,
      characterised in that an opening (11) is arranged in an edge region of the lid (2), the lower edge of which opening forms the stopping surface (18), and that the nose (15) is connected to the lower part (1).
    2. Plastic container of claim 1, characterised in that the members are relaxed in the closed position.
    3. Plastic container of one of the preceding claims characterised in that one of the members is an integral part of the lid (2) and the other of the members is an integral part of the lower part (1).
    4. Plastic container of one of the preceding claims characterised in that the nose (15) is arranged on a hook member (14), which extends over the stopping surface (18) in the safety position.
    5. Plastic container of claim 4,
      characterised in that the hook member (14) comprises a bent head section between the nose and a neck section (12), wherein the neck section (12) is reinforced such that upon exerting the opening force it is less deformed than the head section and/or the nose (15).
    6. Plastic container of one of the preceding claims characterised in that the stopping surface (18) is beveled in the second direction.
    7. Plastic container of one of the preceding claims characterised in that the lower edge of the opening (11) is enlarged by means of a ledge (17).
    8. Plastic container of one of the preceding claims characterised in that in the closed position the nose (15) abuts against an outer region of the stopping surface (18).
    9. Plastic container of one of the preceding claims characterised in that in the closed position the nose (15) extends from an inner side into the opening (11).
    10. Plastic container of claim 9,
      characterised in that in the closed position an outer side of the nose (15) is substantially flush with an outer side of the edge region of the lid (2).
    11. Plastic container of one of the claims 9 or 10, characterised in that for bringing the members into the opened position the opening (11) can be urged elastically outwards and the nose (15) can be urged elastically inwards.
    12. Plastic container of claim 11,
      characterised in that the edge region of the lid (2) extends downwards into a gripping member (9) in the region of the opening (11).
    13. Plastic container of one of the preceding claims characterised in that the nose (15) is arranged on a hook member (14), which extends in the safety position over the stopping surface (18), wherein the hook member (14) comprises a bent head section between the nose and a neck section (12), and wherein the neck section (12) is part of an outer wall (6) of the lower part (1).
