Description

UNSTSTOFFVERSCHLUSS MIT GARANTIEELEMENT PLASTIC LOCK WITH GUARANTEE ELEMENT
Die vorliegende Erfindung betrifft einen Kunststoffver- schluss bestehend aus einem auf einem Behälter befestig¬ baren Unterteil und einem damit über ein Scharnrer ein¬ stückig verbundenen Deckel, mit einem dem Scharnier diame¬ tral gegenüberliegend angebrachten Griffberei ch , der von einem am Unterteil angeordneten Garantieelement mindestens teilweise abgedeckt wird; wobei zusätzlich an einem Ver¬ schlussteil und am Garantieelement Sicherungsmittel vorge¬ sehen sind, die vor der Erstöffnung des Verschlusses in formschlüssiger Verbindung zueinander stehen. Aus der ES-UM-212 ' 300 ist bereits ein Kunststoffver- schluss, der obgenannten Art bekannt. Am Unterteil des Verschlusses ist ein nach aussen vorstehender Haken ange¬ spritzt, der im geschlossenen Zustand des Verschlusses in einen Durchbruch im Deckel eingreift. Ein über Stege am Unterteil angespritztes Garantieband verhindert den Zu- griff, so dass erst nach dessen Entfernung die Sicherungs¬ mittel auseinander gedrückt werden können.The present invention relates to a plastic closure consisting of a lower part which can be fastened to a container and a cover connected to it in one piece via a hinge, with a handle area attached diametrically opposite the hinge, which has at least one guarantee element arranged on the lower part is partially covered; safety means are additionally provided on a closure part and on the guarantee element, which are in a form-fitting connection to one another before the first opening of the closure. A plastic closure of the above-mentioned type is already known from the ES-UM-212 '300. A hook projecting outwards is injection molded onto the lower part of the closure and engages in an opening in the cover when the closure is closed. A guarantee tape molded onto the lower part of webs prevents the gripped so that the securing means can only be pressed apart after its removal.
Eine andere Anordnung der Sicherungselemente zeigt die EP-A-0 ' 141 '591. Hier ist der Haken am Deckel angeordnet und untergreift im geschlossenen Zustand ein Garantieband, welches distanziert von der beckfläche des Unterteiles an diesem über Stege, die wiederum als Sollbruchstel 1en dienen, angespritzt ist. Ferner ist hier auch eine Va¬ riante gezeigt, bei der statt einem Haken mehrere nach aussen vorstehende Vorsprünge am Deckel angebracht sind, die unter das beschriebene Garantieband greifen. Völlig identische Lösungen sind allerdings auch schon aus der US-A-4'487,324 und der DE-A-34 ' 42 ' 152 bekannt.Another arrangement of the securing elements is shown in EP-A-0 '141' 591. Here, the hook is arranged on the cover and, in the closed state, engages under a guarantee band, which is injected at a distance from the surface of the lower part of the lower part, by means of webs which in turn serve as predetermined breaking points. Furthermore, a variant is also shown here, in which instead of a hook, several outwardly projecting projections are attached to the cover, which engage under the described guarantee band. Completely identical solutions are, however, also already known from US-A-4'487 324 and DE-A-34 '42' 152nd
All diese Verschlüsse haben die unangenehme Eigenart, dass entweder am Deckel oder am Unterteil nach aussen vor¬ stehende Teile auch nach der erstmaligen Oeffnung und Ent¬ fernung des Garantieelementes verbleiben. Dies ist einer¬ seits un.schön und andererseits auch unnütz. Wesentlich ist jedoch, dass gerade 'diese verbleibenden hakenförmigen Vor¬ sprünge eine latente Verletzungsgefahr bilden, weil beim sprunghaften Oeffnen oder Schliessen sich der Benutzer die Haut an den Fingern aufschürft. Eine andere Lösung, bei der das obige Problem nicht auf¬ tritt, ist in der US-A-4 ' 696 ' 408 dargestellt. Hier bildet das Garantieelement nur eine Abdeckung der Griffnische, so dass der Deckel nicht gefasst werden kann. Dies bildet jedoch nur teilweise eine Lösung des Problemes, das ein solcher Verschluss zwar ein Garantieelement aufweist, jedoch keine Sicherungsmittel hat. Folglich ist ein sol¬ cher Verschluss nicht geeignet für Behälter, in denen sich ein Innendruck bilden kann. Mangels Sicherungsmittel, die formschlüssig Unterteil und Kappe zusammenhalten, kann der Verschluss sich durch bildende Gase oder durch Unterdruck der Umgebung öffnen, beispielsweise beim Transport von in Flaschen gefüllten Getränke über ein Gebirge. Auch lassen sich die meisten garantiegesicherten Ver¬ schlüsse durch Manipulation öffnen.All of these closures have the unpleasant peculiarity that parts protruding outwards either on the cover or on the lower part remain after the first opening and removal of the guarantee element. On the one hand, this is unattractive and on the other hand it is also useless. However, it is essential that just 'these remaining hooked Vor¬ jumps form a latent risk of injury because the sudden opening or closing the user aufschürft the skin on the fingers. Another solution in which the above problem does not occur is shown in US Pat. No. 4,696,408. Here the guarantee element only covers the handle niche so that the lid cannot be gripped. However, this only partially solves the problem that such a closure has a guarantee element, but has no securing means. Consequently, such a closure is not suitable for containers in which an internal pressure can form. In the absence of securing means that hold the bottom part and cap together in a form-fitting manner, the closure can open due to the formation of gases or due to negative pressure in the environment, for example when transporting bottled drinks over a mountain. Most of the seals secured by guarantee can also be opened by manipulation.
Es ist folglich die Aufgabe der vorliegenden Erfindung, einen- Kunststoffverschl uss , der eingangs genannten Art derart zu verbessern, dass er trotz formschlüssigen Siche¬ rungsmittel nach der Entfernung des Garantieelementes keine Gefahr einer 'Verletzung mehr bietet, aber trotzdem vandalensicher ist. Diese Aufgabe löst ein Kunststoffverschl uss mit den Merk¬ malen des Patentanspruches 1.It is therefore the object of the present invention to improve a plastic closure of the type mentioned at the outset in such a way that, despite positive locking means, after removal of the guarantee element there is no longer any risk of injury, but is nevertheless vandal-proof. This object is achieved by a plastic closure with the features of claim 1.
Die genial einfache Lösung besteht somit darin, dass am Garantieelement mindestens ein zum Zentrum des Ver¬ schlusses • hin gerichtetes vorstehendes Sicherungsmittel angebracht ist, welches for-mschl üssig in eine einsprin¬ gende Oeffnung am Unterteil des Verschlusses eingreift. Mit der Entfernung des Garantieelementes werden gleich¬ zeitig die vorstehenden Teile der Sicherungsmittel ent¬ fernt, womit die Verletzungsgefahr bei späteren Be¬ tätigungen des Verschlusses verunmögl icht ist.The ingeniously simple solution thus consists in that at least one protruding securing means, directed towards the center of the closure, is attached to the guarantee element and positively engages in a recessed opening on the lower part of the closure. When the guarantee element is removed, the protruding parts of the securing means are removed at the same time, which means that the risk of injury when the lock is actuated later is impossible.
Weitere vorteilhafte Ausführungsformen sind in den abhän¬ gigen Patentansprüchen erwähnt und in der nachfolgenden Beschreibung erläutert. In den angefügten Zeichnungen sind zwei Ausführungsbeispiele des Erfindungsgegenstandes dar¬ gestellt. Es zeigt:Further advantageous embodiments are mentioned in the dependent claims and explained in the following description. Two exemplary embodiments of the subject matter of the invention are shown in the attached drawings. It shows:

In der Zeichnung sind zwei Ausführungsformen des Erfin¬ dungsgegenstandes an zwei unterschiedlich gestalteten Kunststoffverschl üssen dargestellt. Der Kunststoffver- schluss gemäss den Figuren 1 und 2 ist für Behälter kon¬ zipiert, die ein dickflüssiges Medium enthalten. Solche Behälter, die beispielswe se Ketchup enthalten, stehen in der Gebrauchslage üblicherweise auf dem Kopf. Aus diesem Grund erweitert sich der Unterteil 1 vom Anschluss mit den Haltemitteln 9 zur Befestigung auf einem Behälter, nach oben zum Deckel 2 hin. Unterteil 1 und Deckel 2 sind einstückig über ein Scharnier 4 miteinander verbunden. Die Ausgestaltung des Scharnieres ist für die Erfindung un¬ wesentlich. Der Unterteil 1 hat somit einen inneren zy¬ lindrischen Teil 10, der durch eine Deckfläche 11 ge¬ schlossen ist, in den eine Ausgusstülle 7 mündet. Am unteren Rand des zylindrischen Teiles 10 des Unterteiles 1 schliesst eine konisch sich von unten nach oben erwei¬ ternde Mantelwand 13 an, die sich bis kurz oberhalb der Deckfläche 11 des zylindrischen Teiles 10 erstreckt. Hier¬ durch ergibt sich ein ringförmiger Hohlraum 14, der durch eine"im Bereich des Scharnieres 4 angelenkte Abdeckfläche 12 verschl iessen lässt.In the drawing, two embodiments of the object of the invention are shown on two differently designed plastic closures. The plastic packaging conclusion according to Figures 1 and 2 is designed for containers containing a viscous medium. Such containers, for example se ketchup, are usually upside down in the use position. For this reason, the lower part 1 widens from the connection with the holding means 9 for attachment to a container, upwards to the cover 2. Lower part 1 and cover 2 are integrally connected to one another via a hinge 4. The design of the hinge is not essential for the invention. The lower part 1 thus has an inner cylindrical part 10, which is closed by a cover surface 11, into which a pouring spout 7 opens. At the lower edge of the cylindrical part 10 of the lower part 1, there is a jacket wall 13 which widens conically from bottom to top and extends to just above the top surface 11 of the cylindrical part 10. Hier¬ by results in an annular cavity 14, the hinged by a "in the area of the hinge 4 covering surface 12 can encrypt ow.
Der über das Scharnier 4 mit dem Unterteil 1 verbundene Deckel 2 hat auf seiner Innenfläche eine Ringwand 8, die als klemmende Ausgussdichtung ausgestaltet ist. Die Ring¬ wand 8 ist genau auf die Ausgusstülle 7 ausgerichtet. Eine zweite, konzentrische Wand 15 ist so gestaltet, dass sie im geschlossenen Zustand des Verschlusses auf die Ab¬ deckfläche 12 drückt. Dem Scharnier 4 diametral gegenüber ist in der vertikalen Wand eine Vertiefung eingelassen, die den Griffbereich 3 bildet. Hier appliziert der Be¬ nutzer mit seinem Daumen eine in Oeffnungsri chtung wir¬ kende Kraft. Um ein Abrutschen zu vermeiden, ist der Griffbereich 3 mit einer Riffelung 16 versehen. Im untersten Teil des Griffberei ches 3 erkennt man eine Ein¬ rastnische 17, die einen eckigen Querschnitt aufweist. Vor der erstmaligen Oeffnung durch den Gebraucher ist am Unterteil 1 ein Garantieelement 5 angebracht. Die Ver¬ bindung zwischen Garantieelement 5 und Unterteil 1 erfolgt über mehrere zerstörbare Verbindungsstellen 18. Die Ver¬ bindungsstellen 18 können beispielsweise als Stege aus¬ gebildet sein, die als So! 1 bruchstel 1en dienen. Beim erstmaligen Schliessen gleitet der Deckel 2 mit seinem Griffbereich 3 hinter das Garantieelement 5. Das Ga¬ rantieelement 5 weist Einrasthaken 19 auf, die einen sägezahnförmi gen Querschnitt haben. Vorzugsweise wird man mehrere Ei nrasthaketi vorsehen, doch genügt im Prinzip ein einziger Einrasthaken 19. Die Einrasthaken 19 greifen in der Garantielage des Verschlusses in die Einrastnische 17 des Deckels 2. Die Einrastnische 17 mit eckigem Quer- schnitt bildet zusammen mit den Einrasthaken 19 die Siche¬ rungsmittel 6. Ein Ausklinken dieser Sicherungsmittel 6, auch mit Werkzeuge, ist nicht möglich, ohne dass dabei die zerstörbaren Verbindungsstellen 18 zwischen dem Unterteil 1 und dem Garantieelement 5 zerstört werden.The lid 2 connected to the lower part 1 via the hinge 4 has on its inner surface an annular wall 8 which is designed as a clamping pouring seal. The ring wall 8 is precisely aligned with the pouring spout 7. A The second, concentric wall 15 is designed such that it presses on the cover surface 12 when the closure is in the closed state. Diametrically opposite the hinge 4 is a recess in the vertical wall, which forms the grip area 3. Here the user applies a force acting in the opening direction with his thumb. To avoid slipping, the grip area 3 is provided with a corrugation 16. In the lowest part of the grip area 3 one can see a latching recess 17 which has an angular cross section. Before the first opening by the user, a guarantee element 5 is attached to the lower part 1. The connection between the guarantee element 5 and the lower part 1 takes place via a plurality of destructible connection points 18. The connection points 18 can be designed, for example, as webs, which are configured as So! Serve 1 fraction. When it is closed for the first time, the cover 2 slides with its grip area 3 behind the guarantee element 5. The guarantee element 5 has latching hooks 19 which have a sawtooth-shaped cross section. Preferably, several egg nrasthaketi will be provided, but in principle a single snap hook 19 is sufficient. In the guaranteed position of the closure, the snap hooks 19 engage in the snap-in niche 17 of the cover 2. The snap-in niche 17 with a square cross Cut forms the securing means 6 together with the snap-in hooks 19. It is not possible to release these securing means 6, even with tools, without destroying the destructible connecting points 18 between the lower part 1 and the guarantee element 5.
Das Garantieelement 5 wird in den meisten Fällen als ab- reissbares Garantieband ausgestaltet sein. Prinzipiell wäre es jedoch ohne weiteres möglich, dieses dickwandig zu gestalten, so dass es genügend Steifigkeit erhält, um unter einem gewissen Kraftaufwand abgedrückt zu werden. Auf jeden Fall bildet das Garantieelement durch sein Vor¬ handensein die sichtbare Unversehrtheitskontron e . Solange das Garantielement vorhanden ist, können die Sicherungs¬ mittel 6 nicht aus dem Eingriff gebracht werden. Die Eiπ- rastnische 17 bildet kein Hinderniss, an dem der Verwender sich verletzen könnte. Die vorstehenden Teile der Siche¬ rung nämlich die Einrasthaken 19 werden gleichzeitig mit der Zerstörung der Verbindungsstellen 18 entfernt. Die Möglichkeit sich an den Einrasthaken somit zu verletzen, ist nicht gegeben.The guarantee element 5 will in most cases be designed as a tear-off guarantee band. In principle, however, it would be easily possible to make this thick-walled, so that it receives sufficient rigidity to be pressed off with a certain amount of force. In any case, the guarantee element, through its presence, forms the visible integrity check. As long as the guarantee element is present, the securing means 6 cannot be disengaged. The corner niche 17 does not form an obstacle against which the user could injure himself. The protruding parts of the fuse, namely the snap-in hooks 19, are removed simultaneously with the destruction of the connection points 18. There is therefore no possibility of injuring yourself on the snap-in hooks.
In den Figuren 3 bis 8 ist ein einteiliger Kunststoffver¬ schluss mit Schnappscharnier dargestellt. Die Bezugszahlen für gleiche Elemente wurden beigehalten. Der Verschluss ist im montierten Zustand auf einem Behälter B darge¬ stellt. Der Behälter kann beispielsweise eine deformier¬ bare Kunststoffflasche sein. Der hier gezeigte Verschluss ist eher für dünnflüssige Medien geeignet. Auch hier er¬ kennt man wiederum den Unterteil 1, der über ein Schnapp¬ scharnier 4 mit dem Deckel 2 verbunden ist. Die Hauptachse zwischen Unterteil 1 und Deckel 2 bildet ein Filmscharnier 20. Ein S-förmiges Federelement 21 bewirkt die Schnapp¬ wirkung des Verschlusses. Das Federelement 21 ist über ein Filmscharnier 22 mit dem Unterteil 1 und über ein Film¬ scharnier 23 mit dem Deckel 2 verbunden. Der Unterteil 1 weist diesmal eine zylindrische Mantelwand 13 und eine innere Ringwand 15 auf. Die innere Ringwand 15 hat wieder¬ um ein Haltemittel 9 zur Befestigung auf dem Behälter B. Während im ersten Ausführungsbeispiel das Haltemittel ein Gewinde ist, ist es in diesem Fall eine Ringnut, in die eine -passende Ringwulst am Behälterhals Aufnahme findet. Ein derartiger Verschluss lässt sich einfach aufdrücken. Im Deckel selber ist wiederum eine Ringwand 8 mit ent¬ sprechender Dichtwulst angespritzt. Die Ringwand 8 passt wiederum klemmend auf die Ausgusstülle 7, welche die Deck¬ fläche 11 des Unterteiles 1 durchsetzt. Die Mantelwand 13 verläuft vom Punkt, der diametral dem Scharnier 4 gegen- überliegt, schräg nach oben bis zum höchsten Punkt, der beim Filmscharnier 20 liegt.FIGS. 3 to 8 show a one-piece plastic closure with a snap hinge. The reference numbers for the same elements were retained. The closure is shown on a container B in the assembled state. The container can be, for example, a deformable plastic bottle. The closure shown here is more suitable for thin media. Here, too, the lower part 1 can be seen, which is connected to the cover 2 by a snap hinge 4. The main axis between lower part 1 and cover 2 forms a film hinge 20. An S-shaped spring element 21 effects the snap action of the closure. The spring element 21 is connected to the lower part 1 via a film hinge 22 and to the cover 2 via a film hinge 23. This time, the lower part 1 has a cylindrical jacket wall 13 and an inner ring wall 15. The inner ring wall 15 again has a holding means 9 for attachment to the container B. While in the first exemplary embodiment the holding means is a thread, in this case it is an annular groove into which a suitable annular bead is received on the container neck. Such a closure can be easily pressed on. An annular wall 8 with a corresponding sealing bead is in turn molded on in the cover itself. The ring wall 8 in turn fits onto the pouring spout 7, which passes through the cover surface 11 of the lower part 1. The jacket wall 13 runs from the point diametrically opposite the hinge 4. overlaps, diagonally up to the highest point, which lies at the film hinge 20.
In den Figuren 3 und 4 ist der Verschluss in seiner Her- stellungslage, das heisst in der Lage, in der er gespritzt wird, dargestellt. In dieser Lage ist das Garantieelement 5 noch über die zerstörbaren Verbindungsstellen 18 fest mit dem Unterteil 1 verbunden. Im Bereich der oberen Kante des Garantielementes 5 ist eine schwenkbare Sperre 27, die in der Herstellungsl age schräg nach oben gerichtet ist, angebracht. Die schwenkbare Sperre 27 ist mit dem Garan¬ tieelement 5 über ein Filmscharnier 28 angelascht. Beim Entformen des Verschlusses kann die Sperre 27 problemlos wegschwenken, so dass keine Gefahr besteht, dass dieses Element beim Entformen des Verschlusses versehrt wird. Die schwenkbare Sperre 27 wirkt mit einer Sperrkante 29 zu¬ sammen, die die untere Begrenzung des Griffberei ches 3 b ldet.FIGS. 3 and 4 show the closure in its production position, that is to say in the position in which it is injected. In this position, the guarantee element 5 is still firmly connected to the lower part 1 via the destructible connection points 18. In the area of the upper edge of the guarantee element 5, a pivotable lock 27, which is directed obliquely upwards in the production position, is attached. The pivotable lock 27 is attached to the guarantee element 5 via a film hinge 28. When the closure is removed from the mold, the lock 27 can pivot away without any problems, so that there is no danger that this element will be damaged when the closure is removed from the mold. The pivotable lock 27 cooperates with a locking edge 29 which forms the lower limit of the grip area 3 b.
Die Figuren 5 und 6 zeigen den erfindungsgemässen Kunst¬ stoffverschluss nach der erstmaligen Schliessung in der Garantielage. Beim erstmaligen Schliessen stösst die Unterkante des Deckels 2 die schwenkbare Sperre 27 nach unten und gleitet an sie vorbei. Die schwenkbare Sperre 27 liegt nun innerhalb des Griffbereiches 3 und steht auf der Sperrkante 29 auf. Die schwenkbare Sperre 27 zusammen mit der Sperrkante 29 bilden wiederum die Sicherungsmittel 6. Das Garanti el eement ist in diesem Fall wiederum als ab- reissbares Garantieband dargestellt, welches endseitig verdickte Grifflaschen 25 aufweist. Das Garantieelement 5 bildet wiederum eine Sichtkontrolle für die Unversehrthei des Produktes. Auch wenn man von oben mit einem dünnen Werkzeug im verbleibenden kleinen Spalt zwischen dem Garantieelement und dem Deckel 2 hineingreifen würde, liesse sich die schwenkbare Sperre 27 wegen seiner Dicke nicht soweit zum Garantieelement 5 hin drücken, dass es nicht mehr von der Sperrkante 29 erfasst werden würde. Somit ist der Garantieverschl uss absolut vandal ensi eher . Das weitgehend den Deckel 2 umgreifende Garantieband 5 erlaubt es auch nicht den Deckel 2 überhaupt zu erfassen. Somit ist eine doppelte Sicherheit gewährleistet.FIGS. 5 and 6 show the plastic closure according to the invention after the initial closure in the guarantee position. When it is closed for the first time, the lower edge of the cover 2 pushes down the pivotable lock 27 and slides past it. The swiveling lock 27 now lies within the grip area 3 and stands on the locking edge 29. The pivotable lock 27 together with the locking edge 29 in turn form the securing means 6. The guarantee element in this case is again shown as a tear-off guarantee strip which has grip tabs 25 that are thickened at the ends. The guarantee element 5 in turn forms a visual inspection for the integrity of the product. Even if one would reach into the remaining small gap between the guarantee element and the cover 2 from above with a thin tool, the pivotable lock 27 could not be pressed so far towards the guarantee element 5 due to its thickness that it would no longer be caught by the locking edge 29 would. So the guarantee is absolutely vandal ensi rather. The guarantee band 5 largely encompassing the cover 2 also does not allow the cover 2 to be gripped at all. This ensures double security.
Ist das Garantieelement 5 einmal entfernt, wie dies in den Figuren 7 und 8 dargestellt ist, so lässt sich der Ver¬ schluss, wie ein gewöhnlicher Schnappverschi uss bedienen, ohne dass dabei irgendwelche vorstehenden Teile am Unter¬ teil oder am Deckel verbleiben, womit wiederum jegliche Verletzungsgefahr definitiv vermieden ist. Sei bstverständ- lieh kann hier das Garantieelement nicht nur, wie darge¬ stellt als Garantieband ausgestaltet sein, sondern wieder¬ um auch als abdrückbares Teil. Ein solches Teil würde man lediglich etwas grösser als den Griffbereich 3 ausge¬ stalten. Die zerstörbare Verbindung zwischen Garantieele¬ ment und Unterteil lässt sich nicht nur als zerstörbare Stege, sondern auch als aufreissbare durchgehende Dünn¬ stelle ausbilden.Once the guarantee element 5 has been removed, as shown in FIGS. 7 and 8, the closure can be operated like an ordinary snap closure without any protruding parts remaining on the lower part or on the cover, which in turn any risk of injury is definitely avoided. Be understood The guarantee element can not only be configured as a guarantee band, as shown, but also as a push-off part. Such a part would only be made somewhat larger than the grip area 3. The destructible connection between the guarantee element and the lower part can be formed not only as a destructible web, but also as a tear-open, continuous thin section.
Es ist erstaunlich, dass die einfache Idee, die Siche¬ rungsmittel 6 am Deckel und Garantieleement änderst anzu¬ ordnen, bisher nie realisiert wurde. Dies ist um so er¬ staunlicher, da dadurch erstmals ein wirklich vandalen- sicherer Garantieverschiuss realisiert werden kann. Die bisher bekannten Garantieverschlüsse liessen sich mit et¬ was Geschick und einem kleinen Schraubenzieher bisher immer öffnen, ohne das Garantieelement, beziehungsweise die Verbindung zwischen Garantieelement und Unterteil zu zerstören. It is surprising that the simple idea of arranging the securing means 6 on the cover and the guarantee element in a different manner has never been realized. This is all the more astonishing since it is the first time that a really vandal-proof guarantee lock can be realized. The previously known guarantee closures could always be opened with some skill and a small screwdriver without destroying the guarantee element or the connection between the guarantee element and the lower part.
