In the case of a can, the structure 9 would correspond, for example, only to an inwardly offset edge. As is known from many boxes.

Abstract

Le capuchon (2) est relié de manière intégrale à la partie inférieure (1) par au moins une bande de fixation (3). Les bandes de fixation (3) sont situées dans un plan (E) coupant la fermeture en plastique, c'est-à-dire le capuchon (2) et la partie inférieure (1) lorsque la fermeture est fermée. Il est possible de réaliser la fermeture avec ou sans charnière (5). La disposition des bandes de fixation selon la manière décrite ci-dessus crée une force de fermeture. De telles fermetures peuvent être utilisées ppour une pluralité de récipients différents, ou faire partie intégrante d'une boîte.The plastic closure, which can be placed over solid or deformable containers or which is an integral part of a container, has a lower part (1) and a cap (2) or cover. The cap (2) is integrally connected to the lower part (1) by at least one fastening strip (3). The fastening strips (3) are located in a plane (E) intersecting the plastic closure, i.e. the cap (2) and the lower part (1) when the closure is closed. It is possible to close with or without a hinge (5). Arranging the fastening bands in the manner described above creates a closing force. Such closures can be used for a plurality of different containers, or be an integral part of a box.

Description

Kunststoffverschluss Plastic closure
Die vorliegende Erfindung betrifft einen Kunststoffverschluss, für feste oder deformierbare Behälter, welcher Verschluss ein integraler Bestandteil des Behälters oder auf diesen aufsetzbar ist, mit einem Unterteil und einer über mindestens einem Spannband mit dem Unterteil integral verbundenen Kappe oder einem Deckel.The present invention relates to a plastic closure for solid or deformable containers, which closure is an integral part of the container or can be placed thereon, with a lower part and a cap or a cover which is integrally connected to the lower part via at least one tensioning strap.
Aus der CH-PS 619 413 ist ein Kunststoff-Verschluss der ob- genannten Art bekannt. Die Funktion des Spannbandes bzw. der Spannbänder ist dabei als Rückhalter umschrieben, der die Kappe, wenn sie einmal geöffnet ist, in der geöffneten Lage hält. Solche Vorkehrungen sind in der Verschlusstechnik seit längerer Zeit in verschiedenster Ausführung bekannt. Die Spannbänder gemäss obgenanntem Patent liegen in der Schliesstellung des Verschlusses in einer Ebene ausserhalb dem Verschluss. Weil aber die Spannbänder in der Schliess- stellung des Verschlusses gespannt sind, haben sie dieFrom CH-PS 619 413 a plastic closure of the above type is known. The function of the tightening strap or the tightening straps is described as a retainer which, when it is opened, holds the cap in the open position. Such arrangements have long been known in a variety of designs in locking technology. The straps according to the above-mentioned patent lie in the closed position of the closure in a plane outside the closure. But because the straps are tensioned in the closed position of the closure, they have it
OMPI Neigung, denselben zu öffnen und der Verschluss sollte folglich immer mit entsprechenden, den Spannbändern gegen¬ über liegenden Verriegelungsorganen versehen 'sein, die diesem Effekt entgegen wirken.OMPI The tendency to open it and the closure should consequently always be provided with corresponding locking members opposite the tensioning straps, which counteract this effect.
Eine andere, bekannte Lösung, dem ungewollten Oeffnungseffekt der Spannbänder entgegen zu wirken ist in derselben Patent¬ schrift dargestellt. Hierbei wird ein integrales Filmschar¬ nier an Unterteil und Kappe derart angeordnet, dass die Dreh¬ achse noch weiter vom Zentrum des Verschlusses ausserhalb desselben zu liegen kommt.Another known solution to counteract the unwanted opening effect of the tensioning straps is shown in the same patent. In this case, an integral film hinge is arranged on the lower part and cap in such a way that the axis of rotation is located further from the center of the closure outside of the latter.
Diese Lösung hat mehrere Nachteile:This solution has several disadvantages:
a) Beim Oeffnungs- und Schliessvorgang resultieren erheb¬ liche Kräfte die enorme Anforderungen an das Filmschar¬ nier stellen. Folglich lassen sich solche Verschlüsse nur aus hochwertigem, teurem Kunststoff realisieren, wie zum Beispiel aus Polypropylen. b) Die Anordnung des Filmscharniers relativ weit ausserhalb des eigentlichen Verschlusses, erfordert erhebliche An¬ passungen an die Verschliessmaschine einer Abfüllanlage. Nicht nur müssen die Greifer entsprechend formlich ge¬ staltet werden, sondern auch die Zuführung des Verschlus¬ ses muss exakt positioniert erfolgen.a) The opening and closing process results in considerable forces which place enormous demands on the film hinge. As a result, such closures can only be made from high-quality, expensive plastic, such as polypropylene. b) The arrangement of the film hinge relatively far outside the actual closure requires considerable adjustments to the sealing machine of a filling system. Not only must the grippers be designed in a correspondingly formal manner, but the closure must also be supplied in a precisely positioned manner.
O PI c) Die Verschliesskraft der Spannbänder ist auch bei relativ entfernter Anordnung des Filmscharniers ausserhalb des Verschlusses nur gering.O PI c) The closing force of the tensioning straps is only slight even when the film hinge is arranged relatively away from the closure.
d) Das Erfordernis, ein Filmscharnier überhaupt haben zu müssen, führt zu einem zwingenden Bewegungsmechanismus, der äusserst einschränkend auf die geometrische Gestal¬ tung von Unterteil und Kappe wirkt. Insbesondere Ver¬ schlüsse mit Aufbauten am Unterteil, wie zum Beispiel eine hochgezogene Ausgussöffnung in die ein in der Kappe angeordneter Zentrierzapfen eingreifen soll, lassen sich kaum bewerkstelligen. Auf jeden Fall erfolgt beim Schliess- beziehungsweise Oeffnungsvorgang eine erheb¬ liche Beanspruchung des Filmscharniers und der gesamte Verschluss wird dabei ständig leicht deformiert. Insbesondere werden die Kanten des Zentrierzapfens und der Ausgusslippe verletzt, wodurch sowohl der Dichteffekt wie die Ausgusseigenschaften des Verschlusses leiden.d) The requirement to have a film hinge at all leads to an imperative movement mechanism which has an extremely restrictive effect on the geometric design of the lower part and cap. In particular, closures with structures on the lower part, such as, for example, a raised pouring opening into which a centering pin arranged in the cap is to engage, can hardly be accomplished. In any case, the film hinge is subjected to considerable stress during the closing or opening process, and the entire closure is constantly slightly deformed in the process. In particular, the edges of the centering pin and the pouring lip are injured, as a result of which both the sealing effect and the pouring properties of the closure suffer.
Aufgabe der Erfindung ist es, einen Verschluss der eingangs beschriebenen Art zu schaffen, der die aufgezählten Nachteile behebt.The object of the invention is to provide a closure of the type described at the outset which overcomes the disadvantages mentioned.
OMPI Diese Aufgabe löst ein Verschluss gemäss Oberbegriff des Patentanspruches, der sich dadurch auszeichnet, dass in ge¬ schlossenem Zustand des Verschlusses das Spannband oder die Spannbänder in einer Ebene verläuft beziehungsweise verlaufen, die den Kunststoffverschluss schneidet.OMPI This object is achieved by a closure according to the preamble of the patent claim, which is characterized in that in the closed state of the closure the tensioning strap or straps runs or run in a plane that intersects the plastic closure.
Bei dieser Anordnung wirkt die resultierende Kraft der Spannbänder als Schliesskraft des Verschlusses auch in geschlossenem Zustand desselben.With this arrangement, the resulting force of the tensioning straps acts as the closing force of the closure, even when the closure is closed.
In einer bevorzugten Ausführung des Verschlusses kann die Spannbandebene parallel zu einer Senkrechten zur Trennebe¬ ne zwischen Unterteil und Kappe verlaufen. Dies bewirkt, dass auch die resultierende Kraft in der Schliesstellung exakt vertikal auf die Trennebene eingeleitet, wird.In a preferred embodiment of the closure, the tensioning band plane can run parallel to a perpendicular to the parting plane between the lower part and the cap. This has the effect that the resulting force in the closed position is also introduced exactly vertically onto the parting plane.
Weitere Ausführungsformen und ihre Vorteile gehen aus den Ansprüchen und der nachfolgenden Beschreibung hervor. In der Zeichnung sind verschiedene Ausführungsvarianten dargestellt und in der Beschreibung erläutert.Further embodiments and their advantages are evident from the claims and the description below. Various design variants are shown in the drawing and explained in the description.

Figur 7a einen Detailausschnitt der Figur 7 zeigtFigure 7a shows a detail of Figure 7
In den Figuren 8 a - d werden vier Oeffnungspositionen eines scharnier¬ losen Verschlusses dargestellt.8a-d show four opening positions of a hinge-free closure.
Der erfindungsgemasse Verschluss besteht immer aus einem Unterteil 1 und einer Kappe oder Deckel 2. Je nach Ver¬ wendung des Verschlusses wird der Unterteil 1 auf einem festen oder deformierbaren, in der Zeichnung nicht dar¬ gestellten Behälter aufgesetzt, oder stellt selber den Unterteil des Behältnisses dar.The closure according to the invention always consists of a lower part 1 and a cap or lid 2. Depending on the use of the closure, the lower part 1 is placed on a fixed or deformable container, not shown in the drawing, or it itself represents the lower part of the container represents.
OMPI In den Figuren 1 - 5 und 8a bis d sind Verschlüsse zum Aufsatz auf feste oder deformierbare Behältnisse gezeigt. Im geschlossenen Zustand des Verschlusses liegen der Un¬ terteil 1 und die Kappe 2 in direkter Berührung aufeinander. Die Berührungsfläche liegt in der sogenannten Trennebene, die in der Zeichnung mit T bezeichnet ist. Das Unterteil 1 und die Kappe oder Deckel 2 sind über mindestens einem Spannband 3 integral miteinander verbunden. Ueber Angüsse 4 sind die Spannbänder 3 vom Unterteil 1, beziehungsweise von der Kappe 2 leicht distanziert. Die Spannbänder 3 ver¬ laufen in einer Ebene E. Die Ebene E schneidet den Verschluss parallel zu dessen Rotationsachse a. In der Variante gemäss den Figuren 1 und 2 sind der Unterteil 1 und die Kappe 2 über ein Filmscharnier 5 miteinander verbunden. Die Schwenkachse des Filmscharniers 5 liegt einerseits in der Trennebene T und andererseits parallel zur Ebene E in der die Spannbänder 3 liegen.OMPI 1 to 5 and 8a to d show closures for attachment to solid or deformable containers. In the closed state of the closure, the lower part 1 and the cap 2 are in direct contact with one another. The contact surface lies in the so-called parting plane, which is designated T in the drawing. The lower part 1 and the cap or lid 2 are integrally connected to one another via at least one tension band 3. The tensioning straps 3 are slightly distanced from the lower part 1 or from the cap 2 via sprues 4. The straps 3 run in a plane E. The plane E intersects the closure parallel to its axis of rotation a. In the variant according to FIGS. 1 and 2, the lower part 1 and the cap 2 are connected to one another via a film hinge 5. The pivot axis of the film hinge 5 is on the one hand in the parting plane T and on the other hand parallel to the plane E in which the tensioning straps 3 are located.
In der geschlossenen Stellung des Verschlusses sind die Spannbänder 3 gespannt, wodurch eine resultierende Kraft vorhanden ist, die innerhalb des Grundrisses des Verschlusses der Ebene E liegt und einen Schliessdruck zwischen Unterteil 1 und Kappe 2 aufrecht erhält. Ist der Verschluss zur Ver¬ wendung auf einem Behältnis mit gashaltigem Inhalt gedacht, so sollte der Schliessdruck möglichst gross sein. Dies lässt sich durch die Dimensionierung und Positionie¬ rung der Spannbänder entsprechend einstellen. Dabei dürfen materialbedingte, physikalische Eigenschaften wie Elastizi¬ tätsmodul und Festigkeit nicht vernachlässigt werden. Eine optimale Lösung lässt sich oftmals nur empirisch finden. Die variablen Grossen bei deren Dimensionierung sind die Breite und die Dicke der Spannbänder 3, sowie der Abstand der Ebene E in der die Spannbänder 3 liegen, zur Rotations¬ achse a des Verschlusses.In the closed position of the closure, the tensioning straps 3 are tensioned, as a result of which a resulting force is present which lies within the outline of the closure of plane E and maintains a closing pressure between the lower part 1 and the cap 2. If the closure is intended for use on a container with a gas content, the closing pressure should be as large as possible. This can be adjusted accordingly by dimensioning and positioning the tensioning straps. Material-related, physical properties such as modulus of elasticity and strength must not be neglected. An optimal solution can often only be found empirically. The variable sizes in their dimensioning are the width and the thickness of the tensioning straps 3 and the distance of the plane E in which the tensioning straps 3 lie to the axis of rotation a of the closure.
Auf die möglichen Verriegelungsorgane die sich mit dem erfindungsgemässen Verschluss kombinieren lassen, wird in dieser Beschreibung nichts ausgeführt.Nothing is explained in this description of the possible locking elements that can be combined with the closure according to the invention.
Selbstverständlich kann der erfindungsgemasse Verschluss mit jeder Art von bekannten Verriegelungsorganen kombiniert wer¬ den, beispielsweise auch mit einem kindersicheren Verriege¬ lungsorgan.Of course, the closure according to the invention can be combined with any type of known locking element, for example also with a childproof locking element.
Der erfindungsgemasse Verschluss lässt sich bei entsprechen¬ der Anpassung auf jeder Gestaltungsform von Unterteil und Kappe anbringen. Die Figuren 3 und 4 zeigen einen Unterteil 1 und eine deckungsgleiche Kappe 2 mit zwölfeckigem Grund- riss. Die Spannbänder 3 die wiederum über Angüsse 4 an der Kappe 2 beziehungsweise am Unterteil 1 befestigt sind, liegen wiede¬ rum in einer Ebene E, die den Verschluss schneidet. Das Scharnier 5 sollte etwa in der der Ebene E nächst gelegenen parallelen Seitenfläche 6 verlaufen.The closure according to the invention can be attached to any design of the lower part and the cap, provided it is adapted accordingly. Figures 3 and 4 show a lower part 1 and a congruent cap 2 with a twelve-sided plan. The tensioning straps 3, which in turn are fastened to the cap 2 or to the lower part 1 via sprues 4, lie again in a plane E which cuts the closure. The hinge 5 should run approximately in the parallel side surface 6 closest to the plane E.
In den Figuren 1 - 4 verläuft die Ebene E in der die Spann¬ bänder 3 liegen parallel zu einer Vertikalen zur Trennebene T, die im vorliegenden Fall identisch der Rotationsachse a ist. Dies ist jedoch keinesfalls zwingend, wie die Ausführung gemäss Figur 5 zeigt. Auch hier verlaufen die Spannbänder 3 in einer Ebene E die wiederum den Verschluss schneidet, je¬ doch ist die Ebene E diesmal zur Vertikalen v zur Trennebene T geneigt. Im dargestellten Beispiel gemäss Figur 5 sind auch die Angüsse 4 , im Gegensatz zu den voran beschriebe¬ nen Beispielen asymetrisch zur Trennebene T angeordnet. Die schräg verlaufenden Spannbänder 3 bewirken zweierlei. Zum einen wirkt die resultierende Andruckskraft zwischen Unterteil 1 und Kappe 2 vermehrt in Richtung zum Zentrum des Verschlusses, zum anderen beeinflusst diese Anordnung eine leichte Veränderung der Schliessbewegung wodurch ein in der Kappe eventuell angeordneter Zentrierzapfen eine exaktere Einführung in einei durch den Zentrierzapfen zu dichtenden Ausguss erhält. Dies trifft insbesondere dann zu, wenn der Verschluss scharnierlos gestaltet ist, wie dies an Hand der Figuren 8 a - 8 d noch beschrieben wird.In FIGS. 1-4, the plane E in which the tensioning bands 3 lie is parallel to a vertical to the parting plane T, which in the present case is identical to the axis of rotation a. However, this is by no means mandatory, as the embodiment according to FIG. 5 shows. Here too, the tensioning straps 3 run in a plane E which in turn cuts the closure, but this time the plane E is inclined to the vertical v to the parting plane T. In the example shown in FIG. 5, the sprues 4 are also arranged asymmetrically to the parting plane T, in contrast to the examples described above. The inclined straps 3 cause two things. On the one hand, the resulting pressure force between the lower part 1 and the cap 2 acts increasingly towards the center of the closure, on the other hand, this arrangement influences a slight change in the closing movement, as a result of which a centering pin which is possibly arranged in the cap receives a more precise introduction into a spout to be sealed by the centering pin . This is particularly true if the closure is designed without a hinge, as will be described with reference to FIGS. 8a-8d.
Durch die asymetrische Anordnung der Angüsse 4 am Unterteil 1 und an der Kappe 2 kann die Position der maximalen Deh¬ nung der Spannbänder 3 entsprechend verschoben werden. Aus der Position der maximalen Dehnung 3 klappt die Kappe in Richtung Schliess- oder Oeffnungsstellung. Die gewünschte Oeffnungsstellung der Kappe 2, in der die Spannbänder 3 ent¬ spannt sind, kann je nach Art des Verschlusses, der Form des Ausgusses oder der Art des zu verschliessenden Behältnisses anders erwünscht sein.Due to the asymmetrical arrangement of the sprues 4 on the lower part 1 and on the cap 2, the position of the maximum expansion of the tensioning straps 3 can be shifted accordingly. From the position of maximum stretch 3, the cap folds in the direction of the closed or open position. The desired opening position of the cap 2, in which the tensioning straps 3 are unclamped, may be desired differently depending on the type of closure, the shape of the spout or the type of container to be closed.
In Figur 6 ist eine Dose, die mit dem erfindungsgemässen Verschluss ausgestaltet ist, dargestellt. Die Dose, und damit auch der Unterteil 1 und die Kappe 2 weisen einen etwa recht¬ eckigen Grundriss auf. Unterteil 1 und Kappe 2 sind hier über drei an derselben Seitenfläche angeordneten Spann¬ bänder 3 miteinander verbunden. Statt der hier dargestellten drei Spannbänder kann der Verschluss selbstverständlich auch aus einem einzigen, dafür etwas breiterem Spannband gebildet sein. Auch hier sind wiederum die Spannbänder 3 zu einer Vertikalen v auf der Trennebene T geneigt angeordnet. Hier¬ zu liegen die Spannbänder 3 in nischenartigen Aussparungen "• , die zur Längsseite 8 der Dose geneigt sind. In Figur 7 ist ein Schnitt entlang der Linie A - A gemäss Figur 6 gezeigt. Aus der Figur 7 a werden die Verhältnisse im Bereich der nischenartigen Aussparung 7 im'Detail ver¬ deutlicht. Die Anordnung von Spannbändern 3 in nischenarti¬ ge Aussparungen 7 lassen sich selbstverständlich auch bei anderen Verschlussformen wie jene in den voran beschriebenen Figuren, realisieren. Die Anordnung der Spannbänder _3 in nischenartige Aussparungen 7 hat den Vorteil, dass keine Teile des Verschlusses über die Kontur des Unterteiles beziehungsweise der Kappe, vorstehen. Dies ist insbesondere von Vorteil, wenn der Verschluss maschinell auf ein Behält¬ nis aufgesetzt wird, muss doch dann der Verschluss nicht mehr auf einen Greifer, entsprechend den vorstehenden Teilen ausgerichtet werden.FIG. 6 shows a can which is designed with the closure according to the invention. The can, and thus also the lower part 1 and the cap 2, have an approximately rectangular outline. The lower part 1 and cap 2 are connected to one another here via three tensioning bands 3 arranged on the same side surface. Instead of the three tightening straps shown here, the closure can of course also be formed from a single, somewhat wider tightening strap. Here again, the tensioning straps 3 are arranged inclined to a vertical v on the parting plane T. To this end, the tensioning straps 3 lie in niche-like recesses which are inclined to the longitudinal side 8 of the can. FIG. 7 shows a section along the line AA according to FIG. 6. The conditions in the area of the niche-like recess 7 are illustrated in detail in FIG. 7a. The arrangement of tensioning straps 3 in niche-like recesses 7 can of course also be realized with other types of closure such as those in the figures described above. The arrangement of the tensioning straps _3 in niche-like recesses 7 has the advantage that no parts of the closure protrude beyond the contour of the lower part or the cap. This is particularly advantageous if the closure is placed mechanically on a container, since the closure then no longer has to be aligned with a gripper in accordance with the above parts.
In den Figuren 8 a - d ist ein scharnierloser Verschluss in verschiedenen Oeffnungen dargestellt. Wiederum handelt es sich hierbei um einen Verschluss mit zylindrischem Unterteil 1 und deckungsgleicher Kappe 2. Die Angüsse 4, für die Spannbänder 3, liegen wiederum asymetrisch zur Trennebene T. Selbstverständlich schneidet auch hier wieder die Ebene E in der die Spannbänder 3 liegen den Verschluss. Das Besondere an vorliegendem Verschluss, besteht darin, dass er kein Scharnier aufweist, sodass Kappe 2 und Unter¬ teil 1 lediglich über die Spannbänder 3 miteinander verbun¬ den sind.- In der Schliesstellung gemäss Figur 8 a verhalten sich die Schliesskräfte, die von den Spannbändern 3 ausge¬ übt werden gleich wie in den voran beschriebenen Varianten. Die Schliesskräft liegt innerhalb der Ebene E und ist durch einen Pfeil F Indizes I dargestellt.FIGS. 8a-d show a hinge-less closure in various openings. Again, this is a closure with a cylindrical lower part 1 and congruent cap 2. The sprues 4, for the tensioning straps 3, are again asymmetrical to the parting plane T. Of course, here again the plane E in which the tensioning straps 3 lie cuts the closure. The special feature of the present closure is that it has no hinge, so that the cap 2 and the lower part 1 are only connected to one another via the tensioning straps 3. In the closed position according to FIG. 8 a, the closing forces behave that of the Tensioning straps 3 are exercised in the same way as in the variants described above. The closing force lies within level E and is represented by an arrow F indices I.
Figur 8 b zeigt denselben Verschluss in leicht geöffneter Zwischenstellung. Die Spannbänder 3 sind nun etwas stärker gedehnt und bewirken nun eine etwas vergrosserte resultieren¬ de Kraft F 2. Die resultierende F 2 verläuft nach wie vor in der Ebene der Spannbänder, die nun jedoch entsprechend dem Oeffnungsgrad der Kappe 2 geneigt ist. Folglich lässt sich die resultierende Kraft F 2 in eine Komponente FS, die be¬ strebt ist die Kappe 2 zu schliessen und in eine Komponente FZ , die geneigt ist die Kappe 2 zum Zentrum, beziehungs¬ weise zur Rotationsachse a , zu ziehen, zerlegen. In dieser Stellung erkennt man bereits, dass der Unterteil 1 einen Aufbau 9 aufweist, der etwa um die Wanddicke der Kappe 2 konzentrisch zur Rotationsachse a gegen innen versetzt ist. Der Aufbau 9 verläuft konisch zu einer mittigen Ausguss¬ öffnung 10.Figure 8 b shows the same closure in a slightly open intermediate position. The tensioning straps 3 are now somewhat more stretched and now produce a somewhat increased resulting force F 2. The resulting F 2 still runs in the plane of the tensioning straps, which, however, is now inclined according to the degree of opening of the cap 2. Consequently, the resulting force F 2 can be broken down into a component FS, which is intended to close the cap 2, and into a component FZ, which is inclined to pull the cap 2 towards the center, or relative to the axis of rotation a. In this position it can already be seen that the lower part 1 has a structure 9 which is offset inward about the wall thickness of the cap 2 concentrically with the axis of rotation a. The structure 9 runs conically to a central pouring opening 10.
OMPI In der Stellung gemäss Figur 8 b ist die fiktive Drehachse parallel zur Ebene E und verläuft exakt durch den Berüh¬ rungspunkt von Kappe 2 und Unterteil 1. Mit zunehmendem Oeffnungswinkel der Kappe 2 nimmt die Komponente FS ab und die Komponente FZ entsprechend zu. Dies geschieht solang, bis die Kraftkomponente FZ die Haftreibung zwischen Unterteil 1 und Kappe 2 überwindet, worauf die Kappe 2 ruckartig bis an den zurück versetzten Aufbau 9 anstösst. Dabei wird die Kappe 2 vollständig ge¬ öffnet, wie in Figur 8 c dargestellt, und die Spannbänder 3 entspannen sich weitgehend, jedoch nicht vollständig, sodass eine geringe resultierende Kraft verbleibt, die die Kappe 2 in der geöffneten Lage gemäss Figur 8 c hält. Weist der Aufbau 9 lediglich eine geringe Bauhöhe auf, wie in Figur 8 c dargestellt, so könnten die Spannbänder 3 die Kappe 2 auf den Aufbau 9 ziehen und damit ein Wieder- verschliessen der Kappe 2 erheblich erschweren. Für diesen Fall ist auf dem Aufbau 9 ein Anschlag 11 angespritzt, der sich im Bereich zwischen den beiden Angüssen 2 des Unter¬ teiles 1 befindet. Der Bewegungsablauf beim Oeffnen, und insbesondere beim Schliessen des Verschlusses wird dadurch optimiert, dass der Uebergang 12 vom Unterteil 1 zum Auf¬ bau 9 gerundet ist. Ist der Aufbau 9 relativ niedrig, wie in Figur 8 c dargestellt, so kann der gerundete Uebergang 12 direkt von der Trennebene T zum Anschlag 11 verlaufen. In der Figur 8 d ist der erfindungsgemasse Verschluss schliesslich noch in der Spritzlage dargestellt. Die Trennebene T ist hier gleichzeitig die Trennebene der Spritzform. Die Spannbänder 3 werden gewölbt gespritzt, sodass sie eine grössere Länge aufweisen, als die Distanz zwischen den beiden entsprechenden Angüssen 4 die der Spritzform entspricht.OMPI In the position according to FIG. 8 b, the fictitious axis of rotation is parallel to plane E and runs exactly through the contact point of cap 2 and lower part 1. As the opening angle of cap 2 increases, the component FS decreases and the component FZ increases accordingly. This continues until the force component FZ overcomes the static friction between the lower part 1 and the cap 2, whereupon the cap 2 abruptly abuts against the set-back structure 9. The cap 2 is completely opened, as shown in FIG. 8 c, and the tensioning straps 3 relax largely, but not completely, so that a small resulting force remains which holds the cap 2 in the open position according to FIG. 8 c. If the structure 9 has only a low overall height, as shown in FIG. 8 c, the tensioning straps 3 could pull the cap 2 onto the structure 9 and thus make it much more difficult to close the cap 2 again. In this case, a stop 11 is molded onto the structure 9, which is located in the area between the two sprues 2 of the lower part 1. The sequence of movements when opening, and in particular when closing the closure, is optimized in that the transition 12 from the lower part 1 to the structure 9 is rounded. If the structure 9 is relatively low, as shown in FIG. 8 c, the rounded transition 12 can run directly from the parting plane T to the stop 11. In FIG. 8 d, the closure according to the invention is finally shown in the spray position. The parting plane T here is also the parting plane of the injection mold. The tensioning straps 3 are injection molded so that they have a greater length than the distance between the two corresponding sprues 4 which corresponds to the injection mold.
Die scharnierlose Ausführung ist selbstverständlich nicht nur bei gerundeten Verschlüssen möglich, sondern prinzi¬ piell bei jeder Gestaltungsform des Verschlusses. Bei der Ausführung gemäss den Figuren 6 und 7 müsste man dann lediglich anstelle von einem Berührungspunkt von einer Berührungslinie sprechen. Hat der Verschluss wie in Figur 6 ersichtlich eine ungerade Anzahl Spannbänder, so müsste man, falls der Aufbau 9 eine zu geringe Bauhöhe aufweist, eine gerade Anzahl von Anschlägen 11 vorsehen. Bei einer Dose, würde der Aufbau 9, beispielsweise lediglich ein nach innen versetzter Rand entsprechen. Wie dies von vielen Schachteln bekannt ist. The hinge-free design is of course not only possible with rounded closures, but in principle with any design of the closure. In the embodiment according to FIGS. 6 and 7, one would then only have to speak of a line of contact instead of a point of contact. If the closure has an odd number of straps, as can be seen in FIG. 6, then if the structure 9 is too low in construction, an even number of stops 11 would have to be provided. In the case of a can, the structure 9 would correspond, for example, only to an inwardly offset edge. As is known from many boxes.
