Abstract

A stopper incorporates a base (1) with a pouring opening (15) and a one-piece cap (2) divided into two sections. The cap (2) is connected to the base (1) through a flexible-strip hinge (3). The part (20) of the cap (2) closer to the flexible-strip hinge (3) and the part (21) further from the hinge are connected to each other through a snap hinge (4). There is at least one opening (17) in the base (1) in which a matching catch (26) on the part (20) engages, whereas the part can still be opened and closed freely through the snap hinge (4).

Description

Die vorliegende Erfindung betrifft einen Kunststoffverschluss mit Schnappscharnier für feste und deformierbare Behältnisse, mit einem Unterteil mit Ausgussöffnung und einer dem Unterteil über ein Filmscharnier fest verbundenen Kappe.The present invention relates to a plastic closure with a snap hinge for solid and deformable containers, with a lower part with a pouring opening and a cap firmly connected to the lower part via a film hinge.

Verschlüsse der oben genannten Art sind in zahllosen Ausführungsformen bekannt. Diese lassen sich jedoch in zwei Grundformen einteilen, nämlich in Verschlüsse mit einem Scharnier, welches nur in der seitlichen Mantelfläche angeordnet ist, wie es beispielsweise aus der DE GM 8416 037 oder WO 82/02532 (Wiesinger) bekannt ist oder in Verschlüsse mit einem Scharnier, welches sich über die seitliche Mantelfläche hinaus in die Deckfläche der Kappe erstreckt. Die zweitgenannte Ausführung weist einen elastisch verformbaren Kniehebel auf, von dem ein Hebelarm in der Deckfläche der Kappe angelenkt ist und zwischen Kappe und Unterteil mindestens ein Filmscharnier angeordnet ist. (US-A 4 386 714)Closures of the type mentioned above are known in countless embodiments. However, these can be divided into two basic shapes, namely closures with a hinge, which is only arranged in the lateral lateral surface, as is known, for example, from DE GM 8416 037 or WO 82/02532 (Wiesinger), or closures with a hinge , which extends beyond the lateral lateral surface into the top surface of the cap. The second-mentioned embodiment has an elastically deformable toggle lever, one of which Lever arm is articulated in the cover surface of the cap and at least one film hinge is arranged between the cap and the lower part. (US-A 4,386,714)

Sämtliche Schnappscharnierverschlüsse der oben genannten Art werden einteilig, im vollständig geöffneten Zustand gespritzt. In einem zweiten gesonderten Arbeitsgang müssen die Verschlüsse in einer Verschliessmaschine ausgerichtet und verschlossen, auf ein Behältnis aufgesetzt werden.All snap hinge locks of the above type are injection molded in one piece, in the fully opened state. In a second separate operation, the closures have to be aligned and closed in a capping machine and placed on a container.

Verschiedene der bekannten Kunststoffverschlüsse mit Schnappscharnier lassen sich in oder unmittelbar nach der Entnahme aus der Spritzform nicht schliessen, da beim Schliessvorgang die federelastisch wirkenden Teile des Schnappscharniers sich noch plastisch verformen würden.Various of the known plastic closures with a snap hinge cannot be closed in or immediately after removal from the injection mold, since the parts of the snap hinge that act resiliently elastic would still deform plastically during the closing process.

Das Verschliessen von Behältnisse ist ein ausserordentlich komplexer Vorgang, weil viele Kunststoffverschlüsse komplizierte Formen aufweisen und daher entsprechend ausgerichtet werden müssen, beovr sie von der Verarbeitungsmaschine gefasst werden können. Dabei kommt es häufiger zu Verstopfungen in den Maschinen.Sealing containers is an extremely complex process because many plastic closures have complicated shapes and therefore have to be aligned accordingly before they can be gripped by the processing machine. Clogging occurs more frequently in the machines.

Es ist daher die Aufgabe der vorliegenden Erfindung einen Verschluss der eingangs genannten Art zu schaffen, daher der eine glatte seitliche Mantelfläche aufweist und eine einfache Weiterverarbeitung ermöglicht.It is therefore the object of the present invention to provide a closure of the type mentioned at the outset, which therefore has a smooth lateral lateral surface and enables simple further processing.

Diese Aufgabe löst ein Kunststoffverschluss mit Schnappscharnier gemäss Oberbegriff des Patentanspruches, der sich dadurch auszeichnet, dass die Kappe, parallel zur Drehachse des Filmscharniers zwischen Kappe und Unterteil, eine dieselbe unterteilendes Schnappscharnier aufweist, wobei der dem Filmscharnier zugewendete Teil der Kappe mindestens, ein Verriegelungselement zur formschlüssigen, bedingt lösbaren Verbindung mit dem Unterteil aufweist, während der dem Filmscharnier abgewendete Teil der geteilten Kappe die Ausgussöffnung im Unterteil verschliesst.This object is achieved by a plastic closure with a snap hinge according to the preamble of the claim, which is characterized in that the cap, parallel to the axis of rotation of the film hinge between the cap and the lower part, has a snap hinge dividing the same, the part of the cap facing the film hinge having at least one locking element for has positive, partially detachable connection to the lower part, while the part of the divided cap facing away from the film hinge closes the pouring opening in the lower part.

Ein derart gestalteter Verschluss lässt sich ohne Beanspruchung des Schnappscharnieres in der Form oder bei der Entnahme aus der Spritzform verschliessen. Eine Bewegung findet lediglich im Filmscharnier zwischen der Kappe und dem Unterteil statt.A closure designed in this way can be closed in the mold without stressing the snap hinge or when it is removed from the injection mold. A movement only takes place in the film hinge between the cap and the lower part.

Eine besonders flache Ausführungsform lässt sich dadurch erreichen, dass das Schnappscharnier aus zwei seitlichen Filmscharniere, die in der Kappenoberfläche liegen und einem Zugband, welches dazwischen, zur Kappenoberfläche nach unten versetzt, verläuft.A particularly flat embodiment can be achieved in that the snap hinge consists of two lateral film hinges, which lie in the cap surface and a tension band, which is offset between them downwards to the cap surface.

Ist der Verschluss relativ gross, so können auf die Kappe auch relativ grosse Kräfte wirken, wobei es dann von Vorteil ist, wenn das Verriegelungelement mindestens ein dorn- oder hakenförmigen Teil an der Kappe ist, welcher in einer den Unterteil durchsetzenden, Durchbruch formschlüssig eingreift.If the closure is relatively large, relatively large forces can also act on the cap, it being advantageous if the locking element is at least one spike or hook-shaped part on the cap which engages in a form-fitting manner in an opening penetrating the lower part.

In der Zeichnung ist eine bevorzugte Ausführungsform des Erfindungsgegenstandes dargestellt und in der nachfolgenden Beschreibung erläutert.In the drawing, a preferred embodiment of the subject matter of the invention is shown and explained in the following description.

Es zeigt:

  • Figur 1 den erfindungsgemässen Kunststoffverschluss im offenen Zustand, wobei der Unterteil von unten, die Kappe von oben sichtbar ist. In
  • Figur 2 ist derselbe Verschluss im Schnitt entlang der Linie 11-11 und in
  • Figur 3 entlang der Linie 111-111 der Figur 1 dargestellt. Derselbe Verschluss ist in
  • Figur 4 nochmals geschnitten entlang der Linie IV-IV in Figur 1 gezeigt.
  • Figur 5 zeigt den Verschluss wieder in der geöffneten Lage wie er gespritzt wird, wobei diesmal der Unterteil von oben und die Kappe von unten sichtbar ist.
It shows:
  • 1 shows the plastic closure according to the invention in the open state, the lower part being visible from below and the cap from above. In
  • Figure 2 is the same closure in section along the line 11-11 and in
  • Figure 3 shown along the line 111-111 of Figure 1. The same lock is in
  • Figure 4 shown again cut along the line IV-IV in Figure 1.
  • FIG. 5 shows the closure again in the open position as it is sprayed, this time the lower part being visible from above and the cap from below.

In Figures 6-9 the new same closure is again shown placed on a tube. In
  • Figure 6 shows the two-part cap of the closure, partially closed.
  • Figure 7 shows a section through the closed part of the closure along the section line VII-VII in Figure 6. In

  • Figure 9 shown in top view.

Der Kunststoffverschluss besteht aus den beiden Hauptteilen, Unterteil 1 und Kappe 2. Unterteil 1 und Kappe 2 sind über ein relativ schmales Filmscharnier 3 miteinander verbunden. Im Unterteil 1 verlaufen drei konzentrische Ringwände. Die innerste Ringwand 11 ist ein Dichtring, welcher im Querschnitt gegen unten konisch verläuft. Er dient dazu, das zu verschliessende Behältnis gegenüber dem Unterteil des Verschlusses zu dichten. Die mittlere Ringwand 12 dient der Befestigung des Kunststoffverschlusses auf das zu verschliessende Behältnis. Dies kann ein Klemmwulst oder wie im dargestellten Beispiel ein Innengewinde 14 sein. Die äusserste Ringwand 13 stellt zugleich die äussere Mantelfläche des Verschlusses dar und dient der ästhetischen Gestaltung des Verschlusses und optischer Anpassung an das zu verschliessende Behältnis B und gibt den Verschluss zusätzliche Festigkeit (siehe Figur 6-9). Exzentrisch innerhalb der inneren Ringwand 11 weist der Unterteil 1 eine Durchgangsöffnung auf, den Ausguss 15.The plastic closure consists of the two main parts, lower part 1 and cap 2. Lower part 1 and cap 2 are connected to one another via a relatively narrow film hinge 3. In the lower part 1 there are three concentric ring walls. The innermost ring wall 11 is a sealing ring which is conical in cross section towards the bottom. It serves to seal the container to be sealed against the lower part of the closure. The middle ring wall 12 is used to fasten the plastic closure onto the container to be closed. This can be a clamping bead or, as in the example shown, an internal thread 14. The outermost ring wall 13 also represents the outer circumferential surface of the closure and serves for the aesthetic design of the closure and optical adaptation to the container B to be closed and gives the closure additional strength (see FIGS. 6-9). Eccentrically within the inner ring wall 11, the lower part 1 has a through opening, the spout 15.

Der Unterteil 1 wird diametral von einer U-förmigen Nut 16 mit rechtwinkligem Querschnitt durchsetzt, welche zentrisch zum Filmscharnier 3 quer über den Unterteil verläuft. Die Tiefe der Nut 16 entspricht der Höhe der Kappe 2. Im Boden der Nut sind zwischen der mittleren 12 und äusseren Ringwand 13 im Bereich näher dem Filmscharnier 3 zwischen Kappe 2 und Unterteil 1, zwei Durchbrüche 17 sichtbar (Figur 1,4 und 5). Die Durchbrüche 17 verlaufen möglichst nahe an den Seitenwänden 18 der Nut 16.The lower part 1 is penetrated diametrically by a U-shaped groove 16 with a rectangular cross section, which is centered on the film hinge 3 across the lower part runs. The depth of the groove 16 corresponds to the height of the cap 2. Two openings 17 are visible in the bottom of the groove between the middle 12 and the outer ring wall 13 in the area closer to the film hinge 3 between the cap 2 and the lower part 1 (FIGS. 1, 4 and 5). . The openings 17 run as close as possible to the side walls 18 of the groove 16.

Im dargestellten Beispiel ist die zweiteilige Kappe 2,die einstückig mit dem Unterteil 1 fest verbunden ist, balkenförmig gestaltet. Die Zweiteilung der einstückigen Kappe 2 ist von oben (Figur 1 und 9) nicht ersichtlich. In Figur 1 ist lediglich die Schwenkachse A zur Erläuterung strichliniert eingezeichnet. Auf diese Art ist auch von der Oberseite klar ersichtlich, was mit dem Filmscharnier 3 zugewandten 20 und Filmscharnier 3 abgewandten Teil 21 der Kappe 2 gemeint ist. Im geschlossenen Zustand des Verschlusses liegt die Oberfläche 22 der Kappe bündig mit der Oberfläche 19 des Unterteiles und mit dieser parallelen. Der dem Filmscharnier 3 nahe Bereich 20 der Kappe 2 ist wesentlich kleiner, als der dem Filmscharnier 3 abgewandte Bereich 21. Beide Bereiche 20, 21 der Kappe sind über ein Schnappscharnier 4 miteinander einstückig verbunden.In the example shown, the two-part cap 2, which is integral with the lower part 1, is designed in the form of a bar. The bisection of the one-piece cap 2 cannot be seen from above (FIGS. 1 and 9). In Figure 1, only the pivot axis A is shown in dashed lines for explanation. In this way, it can also be clearly seen from the top what is meant by the part 21 of the cap 2 facing the film hinge 3 and the part 21 facing away from the film hinge 3. In the closed state of the closure, the surface 22 of the cap lies flush with the surface 19 of the lower part and is parallel to it. The area 20 of the cap 2 close to the film hinge 3 is considerably smaller than the area 21 facing away from the film hinge 3. Both areas 20, 21 of the cap are integrally connected to one another via a snap hinge 4.

Das Schnappscharnier 4 ist so aufgebaut, dass der Querschnitt der Kappe 2 im Bereich der Schwenkachse 17 beidseitig keilförmig bis auf je ein Filmscharnier 23 verdünnt ist. Zwischen den beiden Filmscharnieren 23, die in der Oberfläche 22 der Kappe 2 verlaufen, ist ein Zugband 24 angeordnet. Das Zugband 24 ist gegenüber der Ebene der Oberfläche 22 parallel nach unten versetzt. In der gestreckten Lage in der die Kappe gespritzt wird, ist das Zugband spannungsfrei.The snap hinge 4 is constructed such that the cross section of the cap 2 in the region of the pivot axis 17 is wedge-shaped on both sides except for one film hinge 23 each. A drawstring 24 is arranged between the two film hinges 23, which run in the surface 22 of the cap 2. The tension band 24 is offset parallel downwards relative to the plane of the surface 22. In the stretched position in which the cap is injected, the drawstring is free of tension.

Die Kappe 2 ist rundum mit einem Rand 25 umgeben, welcher in der Höhe der Tiefe der Nut 16 entspricht. Aus dem, den Filmscharnier 3, zwischen Kappe 2 und Unterteil 1, nahen Bereich der Kappe ist an dessen Rand 25 beidseitig je ein hakenförmiger Verriegelungsteil 26 angespritzt. Im geschlossenen Zustand des Verschlusses greifen die Teile 26 durch die Durchbrüche 16 im Unterteil 1 hindurch und haken an dessen Unterseite ein. Ohne besondere Manipulationen lässt sich nun dieser hintere Teil 20 der Kappe 2 nicht mehr öffnen (siehe Figur 6 und 7). Der vordere Kappenteil 21 hingegen bleibt über das Schnappscharnier 4 leicht öffenbar. Das Filmscharnier 3 hat somit lediglich eine Hilfsfunktion während des ersten Schliessvorganges des Gesamtverschlusses. Einmal geschlossen bleibt das Scharnier 3 ausser Funktion. Die eigentliche Schliessfunktion hat lediglich der Bereich 21 der Kappe, der sich über die Ausgussöffnung 15 im Unterteil hinweg erstreckt und auf ein die Ausgussöffnung 15 passendes zapfenförmiges Dichtelement 27 hat.The cap 2 is surrounded all around with an edge 25 which corresponds in height to the depth of the groove 16. From the film hinge 3, between the cap 2 and the lower part 1, near the area of the cap, a hook-shaped locking part 26 is injection-molded onto both sides of its edge 25. In the closed state of the closure, the parts 26 reach through the openings 16 in the lower part 1 and hook on the underside thereof. This rear part 20 of the cap 2 can no longer be opened without special manipulations (see FIGS. 6 and 7). The The front cap part 21, on the other hand, remains easily openable via the snap hinge 4. The film hinge 3 thus only has an auxiliary function during the first closing process of the overall closure. Once closed, hinge 3 remains inoperative. The actual closing function is only in the area 21 of the cap, which extends over the pouring opening 15 in the lower part and has a peg-shaped sealing element 27 that fits the pouring opening 15.

Zur leichteren Bedienung des Kappenteiles 21 ist im Unterteil 1 eine Nische 10 vorhanden, damit man leichter mit der Fingerkuppe unter den zu öffnenden Kappenbereich 21 kommen kann.For easier operation of the cap part 21, a niche 10 is provided in the lower part 1, so that it is easier to get under the cap area 21 with the fingertip.

Der in der Lage gemäss Figur 1 gespritzte Verschluss kann somit durch einfaches Schwenken um das Filmscharnier 3 verschlossen werden, ohne das Schnappscharnier 4 zu betätigen. Dieser Vorgang kann beispielsweise direkt beim Oeffnen der Spritzform erfolgen, so dass dann der geschlossene Verschluss aus der Form gestossen werden kann. Ein nachträgliches Ausrichten und Verschliessen der Verschlüsse in teuren Spezialmaschinen entfällt somit. Neben der bevorzugten dargestellten Lösung sind verschiedenen Varianten denkbar. So kann beispielsweise am Kappenteil 20 statt zwei seitlichen hakenförmigen Eingriffsteile 26 auch nur ein zentrischer, haken- oder dornenförmiger Teil vorgesehen sein, der dann in einen entsprechenden Durchbruch 17 eingreift.The closure injection-molded in the position according to FIG. 1 can thus be closed by simply pivoting around the film hinge 3 without actuating the snap hinge 4. This process can take place, for example, directly when the injection mold is opened, so that the closed closure can then be pushed out of the mold. A subsequent alignment and closing of the closures in expensive special machines is therefore not necessary. In addition to the preferred solution shown, various variants are conceivable. For example, instead of two lateral hook-shaped engagement parts 26, only a central, hook-shaped or thorn-shaped part can be provided on the cap part 20, which then engages in a corresponding opening 17.

Die nur bedingt lösbare Verbindung zwischen dem Kappenteil 20 und dem Unterteil 1 kann aber auch mittels kantigen Wulsten an den Seitenrändern 25 des Kappenteiles 20 erfolgen, die in entsprechenden Rillen in den Seitenwänden 18 der Nut 16 eingreifen. Diese Anordnung kann auch sinnvoll sein im vorderen Kappenbereich 21, um eine gewisse, jedoch leicht lösbare Arretierung des zu öffnenden Teiles zu erreichen.The only partially detachable connection between the cap part 20 and the lower part 1 can also take place by means of angular beads on the side edges 25 of the cap part 20, which engage in corresponding grooves in the side walls 18 of the groove 16. This arrangement can also be useful in the front cap area 21 in order to achieve a certain, but easily releasable locking of the part to be opened.

Auch das Schnappscharnier 4 kann verschieden gestaltet sein. So können, statt lediglich ein Zugband, zwei Zugbänder vorgesehen sein, die parallel verlaufen. Dadurch wird das Filmscharnier in drei Teile unterteilt die jedoch genau fluchtend verlaufen. Erfindungswesentlich ist weder die Form der Kappe oder des Unterteiles, noch die Gestaltung des Filmscharniers zwischen den beiden Teilen. So kann ohne weiteres die Kappe den gesamten Unterteil decken und auch die Aufteilung der Kappe exakt hälftig sein. Wichtig ist jedoch die Verlagerung des Schnappscharniers aus den Verbindungsbereich zwischen Kappe und Unterteil in die Kappe selber. Dies bedingt jedoch eine nur bedingt lösbare Verbindung zwischen dem zu fixierenden Kappenteil und dem Unterteil des Verschlusses.The snap hinge 4 can also be designed differently. Thus, instead of just one drawstring, two drawstrings can be provided which run in parallel. This divides the film hinge into three parts, which, however, run exactly in line. Essential to the invention is neither the shape of the cap or the lower part, nor the design of the film hinge between the two parts. So the cap can easily cover the entire lower part and the division of the cap can be exactly half. However, it is important to move the snap hinge from the connection area between the cap and the lower part into the cap itself. However, this requires an only partially detachable connection between the cap part to be fixed and the lower part of the closure.
