Abstract

A one-piece plastic closure comprises a lower part (1), a lid (3) and a snap hinge (6). In order to connect the lower part directly to the lid (3), the snap hinge comprises one or more film hinges (8) aligned in the main axis of rotation (10). The snap hinge comprises at least one elastic element (14) which, in the closed position, does not project beyond the external profile of the adjacent sections of the lower part and of the lid, but is as flush as possible with them. The elastic element is connected to the lid and the lower part by linear articulations (16) parallel to the main axis of rotation, at a certain distance from the latter. At least one film hinge is located with the necessary play on the outer faces of the lower part and of the lid. The sections of the lower part and of the lid immediately adjacent to the film hinge have marginal surfaces (22, 24) inclined to their outer face (bevelled edges) which in the closed position are adjacent and in the open position swivel apart. In the closed position of such a closure, the film hinges do not project outward. Instead, they are located in the outer wall of the lower part and in one edge or outer wall of the lid. The lid and the lower part can also be connected by a small strip (30) or several aligned small strips. In this case, the small strip is fully retracted inside the outer profile when the closure is closed.

Description

Die Erfindung bezieht sich auf einen Verschluß mit einem Schnappschar­nier, das den Unterteil und den Deckel des Verschlusses miteinander ver­bindet, im übrigen mit den im Oberbegriff von Anspruch 1 genannten Merk­malen.The invention relates to a closure with a snap hinge that connects the lower part and the lid of the closure to each other, otherwise with the features mentioned in the preamble of claim 1.

Verschlüsse dieser Art sind bekannt. So zeigt z.B. die US-PS 4 487 324 - OSTROWSKY / SEAQUIST einen Verschluß mit Schnappscharnier, bei dem zwei in die Hauptdrehachse fallende Filmscharniere beiderseits eines einzigen Federelements angeordnet sind. Dagegen zeigt die DE-GMS 87 05 035 - WEE­NER PLASTIK an einem Verschluß die umgekehrte Anordnung des Schnapp­scharniers, nämlich zwei Federelemente, die beiderseits eines einzigen Filmscharniers angeordnet sind.Closures of this type are known. For example, US Pat. No. 4,487,324 - OSTROWSKY / SEAQUIST discloses a snap hinge closure in which two film hinges falling in the main axis of rotation are arranged on either side of a single spring element. In contrast, DE-GMS 87 05 035 - WEENER PLASTIK shows the reverse arrangement of the snap hinge on a closure, namely two spring elements which are arranged on both sides of a single film hinge.

Wie es beide Schriften zeigen, besonders deutlich aber die US-PS, stehen Teile von Unterteil und Deckel, die durch die Filmscharniere miteinander verbunden sind, relativ weit in den Raum vor. Dies ist eine Folge der Tatsache, daß Unterteil und Deckel in einer Lage nach Figur 5 der US-PS im Spritzguß hergestellt werden. Da nun die Form für den Unterteil und die für den Deckel rundherum, also auch zwischen beiden, eine bestimmte Wandstärke haben muß, blieb nach dem Stand der Technik nichts anderes übrig, als diese Formwandstärken durch die Abschnitte zu überbrücken, die von Unterteil und Deckel zum Filmscharnier führen.As both documents show, but particularly clearly the US-PS, parts of the lower part and lid, which are connected by the film hinges, protrude relatively far into the room. This is a consequence of the fact that the lower part and cover are injection molded in a position according to FIG. 5 of the US patent. Since the shape for the lower part and that for the cover all around, that is to say between the two, must have a certain wall thickness, there was no other option in the prior art than to bridge these shape wall thicknesses through the sections from the lower part and cover to Guide film hinge.

Die vorliegende Erfindung soll sich auf Verschlüsse von besonders gutem Aussehen beziehen. Hierzu gehört unter anderem, daß die Außenform des Federelements im Schließzustand der Außenform der benachbarten Abschnit­te von Unterteil und Deckel entspricht, so daß sich im Idealfall eine glatte, ununterbrochene Außenhaut ergibt, im Gegensatz z.B. zur US-PS 3 628 215 - EVERBURG / AMERICAN OPTICAL CORP., wo das Federelement im Schließzustand im Innern eineg Behälters liegt, so daß sich eine von au­ßen gut erkennbare Rinne ergibt, die unschön wirkt.The present invention is said to relate to closures of particularly good appearance. This includes, inter alia, that the outer shape of the spring element in the closed state corresponds to the outer shape of the adjacent sections of the lower part and lid, so that ideally there is a smooth, uninterrupted outer skin, in contrast, for example, to the US-PS 3 628 215 - EVERBURG / AMERICAN OPTICAL CORP., Where the spring element lies inside a narrow container in the closed state, so that there is a gutter which is clearly visible from the outside and has an unsightly effect.

Anspruch 2, für den selbständiger Schutz geltend gemacht wird, bezieht sich auf einen Verschluß dieser Art, bei dem jedoch gemäß Merkmal c) seines Oberbegriffs als Filmscharnier ein Bändchen oder zwei oder mehr miteinander fluchtende Filmscharnier-Bändchen dienen.Claim 2, for which independent protection is asserted, relates to a closure of this type, in which, however, according to feature c) of its preamble a ribbon hinge or two or more aligned film hinge ribbons serve as a film hinge.

Durch die vorliegende Erfindung soll ein Verschluß der im Oberbegriff von Anspruch 1 genannten Art so ausgestaltet werden, daß das in die Hauptdrehachse fallende Filmscharnier in Schließstellung nicht nach au­ßen vorsteht. Entsprechendes gilt für zwei oder mehr in die Hauptdre­hachse fallende Filmscharniere. Ein Verschluß nach dem Oberbegriff von Anspruch 2 soll durch die Erfindung so ausgestaltet werden, daß in Schließstellung kein Teil des Bändchens nach außen vorsteht. Trotzdem soll aber der aus Deckel, Unterteil und Scharnier bestehende Verschluß in einem einzigen Spritzvorgang herstellbar sein.The present invention is intended to design a closure of the type mentioned in the preamble of claim 1 in such a way that the film hinge falling into the main axis of rotation does not protrude outwards in the closed position. The same applies to two or more film hinges falling in the main axis of rotation. A closure according to the preamble of claim 2 is to be designed by the invention so that no part of the ribbon protrudes outwards in the closed position. Nevertheless, the closure consisting of cover, lower part and hinge should be able to be produced in a single injection molding process.

Diese Aufgabe wird durch die Merkmale der Ansprüche 1 oder 2 gelöst. (In den folgenden Ausführungen werden auch die in den Ansprüchen definierten Begriffe verwendet.)This object is solved by the features of claims 1 or 2. (The terms defined in the claims are also used in the following explanations.)

Nach dem kennzeichnenden Teil von Anspruch 1 liegt das eine Filmschar­nier oder liegen die miteinander fluchtenden Filmscharniere in den Au­ßenflächen von Unterteil und Deckel. Nach dem kennzeichnenden Teil von Anspruch 2 liegen die Ränder des Bändchens oder der miteinander fluch­tenden Bändchen in den Außenflächen von Unterteil und Deckel. Dienen zur direkten Verbindung von Unterteil und Deckel zwei oder in Sonderfällen mehrere auch als Bändchen ausgestaltete Filmscharniere, die alle mitein­ander fluchten und in der Hauptdrehachse liegen, so müssen die Außenwand des Unterteils und die benachbarte aüßerste Kante des Deckels im Bereich dieser Filmscharniere gerade sein.According to the characterizing part of claim 1, there is a film hinge or the film hinges are aligned with one another in the outer surfaces of the lower part and cover. According to the characterizing part of claim 2, the edges of the ribbon or the aligned ribbons lie in the outer surfaces of the lower part and lid. If two or, in special cases, several film hinges designed as tapes are used for the direct connection of the lower part and lid, all aligned with one another and lying in the main axis of rotation, the outer wall of the lower part and the adjacent outermost edge of the lid must be straight in the area of these film hinges.

Nach der Erfindung stehen keine zu dem oder den Filmscharnier(en) füh­renden Bestandteile oder Teile des oder der Bändchen nach außen vor. Dies wird dadurch ermöglicht, daß die an das Filmscharnier oder die Filmscharniere unmittelbar anschließenden Abschnitte von Unterteil und Deckel schräggestellte Ränder (Schrägränder) haben. Die Schrägränder müssen in einem solchen Sinne schräggestellt sein, daß sie in Schließ­stellung einander benachbart und in Offenstellung auseinander geschwenkt sind.According to the invention, no components or parts of the ribbon or ribbons leading to the film hinge (s) project outwards. This is made possible by the fact that the sections of the lower part and lid immediately adjoining the film hinge or the film hinges have inclined edges (inclined edges). The sloping edges must be inclined in such a way that they are adjacent to each other in the closed position and pivoted apart in the open position.

Hierdurch liegt im Gegensatz zu Figur 5 von OSTROWSKY / SEAQUIST in Of­fenstellung der angelenkte Boden des Deckels, sofern er eben oder einge­buchtet ist, oberhalb des Filscharniers oder der Filmscharniere. Unter­teil und Deckel lassen sich infolgedessen in einer Form herstellen, die keine Trennwand oder Trennwände zwischen beiden besitzt, wie es sich aus der folgenden Figurenbeschreibung ergibt.In contrast to FIG. 5 by OSTROWSKY / SEAQUIST, in the open position the hinged bottom of the lid, if it is flat or indented, lies above the film hinge or the film hinges. As a result, the lower part and cover can be produced in a form which has no partition or partitions between the two, as is evident from the following description of the figures.

Weiterbildungen der ErfindungDevelopments of the invention

ergeben sich aus den Unteransprüchen.result from the subclaims.

Liegen die Schrägränder nach Anspruch 3 in Schließstellung aufeinander, so wird hierdurch für eine exakt richtige Lage des oder der Filmschar­niere, auch in Form von Bändchen, in Schließstellung gesorgt. Trotz un­vermeidbarer Toleranzen wird dann durch Aneinanderdrücken der Schrägrän­der eine Lage des Filmscharniers oder der Filmscharniere an der Ecke zwischen den Außenflächen von Unterteil und Deckel erzielt. Bändchen werden beim Schließvorgang vollständig einwärts gezogen, so daß von ih­nen kein Abschnitt nach außen vorsteht.If the sloping edges lie on top of one another in the closed position, this ensures that the film hinge or hinges are in the correct position, also in the form of tapes, in the closed position. Despite unavoidable tolerances, a position of the film hinge or the film hinges on the corner between the outer surfaces of the lower part and the lid is then achieved by pressing the inclined edges together. Wristbands are pulled fully inwards during the closing process so that no section protrudes outwards.

Nach Anspruch 4 können die Schrägränder eben sein, nach Anspruch 5 dage­gen zueinander passende Krümmungen haben.According to claim 4, the inclined edges can be flat, according to claim 5, however, have matching curvatures.

Nach Anspruch 6 lassen sich innerhalb der Schrägränder Stufen anordnen, durch die der eine Teil (Unterteil oder Deckel) beim Schließvorgang den anderen in seine richtige Lage zieht. Die Stufen werden hierbei so an­geordnet, daß der formstabilere Teil den anderen hereinzieht.According to claim 6, steps can be arranged within the inclined edges, through which one part (lower part or cover) pulls the other into its correct position during the closing process. The steps are arranged so that the more dimensionally stable part pulls the other in.

Nach Anspruch 7 können die Stufen durch einen vorspringenden Abschnitt am Schrägrand des Deckels und einen zurückspringenden Abschnitt am Schrägrand des Unterteils gebildet werden, so daß beim Zuklappen der Deckel gegenüber der Rückwand des Unterteils nach innen gezogen wird.According to claim 7, the steps can be formed by a projecting section on the inclined edge of the cover and a recessed section on the inclined edge of the lower part, so that when the cover is closed, it is pulled inwards relative to the rear wall of the lower part.

Wird das Filmscharnier nach Anspruch 2 als Bändchen ausgebildet, was für einige Ausführungsformen zweckmäßig ist, so läßt sich nach Anspruch 9 zuverlässig dafür sorgen, daß das Bändchen in seiner vollen Breite beim Zuklappen einwärts gezogen wird, so daß keine Bändchenabschnitte in Schließstellung nach außen vorstehen.If the film hinge according to claim 2 is designed as a ribbon, which is useful for some embodiments, it can be ensured according to claim 9 that the ribbon is pulled in its full width when folded, so that no ribbon sections protrude outwards in the closed position.

Verschlüsse nach der Erfindung werden aus elastischem Kunststoff herge­stellt, der die nötige Festigkeit für Scharniere hat, vorzugsweise aus Polypropylen.Closures according to the invention are made of elastic plastic, which has the necessary strength for hinges, preferably of polypropylene.

Der Begriff "Schnappscharnier" soll besagen, daß der Deckel beim Öffnen und Schließen über einen Totpunkt bewegt werden muß und daß der Deckel aus der Totpunktlage, die sich irgendwo innerhalb des Schwenkweges be­findet, von selbst entweder in Offenstellung oder in Schließstellung schnappt und dort verharrt.The term "snap hinge" is intended to mean that the lid has to be moved over a dead center when opening and closing and that the lid snaps from the dead center position, which is located somewhere within the swivel path, either in the open position or in the closed position and remains there.

Der Verschluß nach Figur 1 und 2 hat einen Unterteil 1 und einen Deckel 3. Der Boden 4 des Deckels ist mit der Rückwand 2 des Unterteils durch ein Schnappscharnier 6 verbunden. Das Schnappscharnier hat zwei außen liegende Filmscharniere 8, die miteinander fluchten und gemeinsam in die Hauptdrehachse 10 fallen. Zwischen den beiden Filmscharnieren 8 haben Unterteil und Deckel je einen Ausschnitt, in dem ein Federelement 14 un­tergebracht ist. Das Federelement ist durch linienförmige Gelenkstellen 16 und 18 mit dem Boden 4 des Deckels und der Rückwand 2 des Unterteils verbunden.The closure according to FIGS. 1 and 2 has a lower part 1 and a lid 3. The bottom 4 of the lid is connected to the rear wall 2 of the lower part by a snap hinge 6. The snap hinge has two outer film hinges 8, which are aligned with one another and together fall into the main axis of rotation 10. Between the two film hinges 8, the lower part and cover each have a cutout in which a spring element 14 is accommodated. The spring element is connected by linear articulation points 16 and 18 to the bottom 4 of the cover and the rear wall 2 of the lower part.

Der Unterteil 1 hat eine ebene Rückwand 2 mit einer Außenfläche 2a, in die die beiden Filmscharniere 8 fallen. Der Boden 4 des Deckels 3 hat eine ebene Außenfläche 4a, in die die beiden Filmscharniere ebenfalls fallen. Die Außenflächen 2a und 4a von Rückwand und Deckel nehmen außer­dem die linienförmigen, geraden Gelenkstellen 16 und 18 auf. Diese Gelenkstellen sind ebenso ausgebildet wie Filmscharniere, werden aber hier zur Unterscheidung von den in die Hauptdrehachse fallenden Film­scharnieren "linienförmige Gelenkstellen" genannt.The lower part 1 has a flat rear wall 2 with an outer surface 2a, into which the two film hinges 8 fall. The bottom 4 of the lid 3 has a flat outer surface 4a, in which the two film hinges also fall. The outer surfaces 2a and 4a of the rear wall and cover also receive the linear, straight articulation points 16 and 18. These articulation points are designed in the same way as film hinges, but are here called "linear articulation points" to distinguish them from the film hinges falling in the main axis of rotation.

Die Rückwand 2 des Unterteils steht zu beiden Seiten des Federelements 6 über den Boden 20 des Unterteils nach oben vor. Sie endet oben in Schrägrändern 22, die so angeordnet sind, daß ihre obere, in der Außen­fläche 2a liegende Kante mit dem Filmscharnier 8 zusammenfällt. Der Schrägrand 24 des Bodens 4 des Deckels ist so angeordnet, daß seine am meisten vorstehende Kante (links in Figur 2) in der Außenfläche 4a des Deckelbodens liegt und mit dem Filmscharnier 8 zusammenfällt.The rear wall 2 of the lower part protrudes upwards on both sides of the spring element 6 via the bottom 20 of the lower part. It ends at the top in oblique edges 22 which are arranged such that their upper edge lying in the outer surface 2a coincides with the film hinge 8. The sloping edge 24 of the base 4 of the cover is arranged such that its most protruding edge (on the left in FIG. 2) lies in the outer surface 4a of the cover base and coincides with the film hinge 8.

Für das Filmscharnier oder die Filmscharniere 8 sind verschiedene be­kannte Ausführungsformen möglich. Sie können eine Knickstelle minimaler Breite sein oder ein schmales Band. Ihre innere und/oder äußere Fläche können gekrümmt sein, so daß die konvexe Seite der Krümmung in Figur 2 oder 3 nach links oben weist. Die in Figur 3 schräge Fläche, die aus den beiden Schrägrändern 22 und 24 gebildet wird, kann zwischen diesen Schrägrändern eine Rinne aufweisen, wodurch sich eine Schwachstelle er­gibt.Various known embodiments are possible for the film hinge or the film hinges 8. It can be a kink of minimal width or a narrow band. Their inner and / or outer surface can be curved, so that the convex side of the curvature in Figure 2 or 3 points to the top left. The inclined surface in FIG. 3, which is formed from the two inclined edges 22 and 24, can have a groove between these inclined edges, which results in a weak point.

Das Federelement 14 kann, je nach der Außenform des Verschusses, ge­krümmt sein (Figur 2) oder gewinkelt (Figur 3). Der Winkel kann in einem Bereich von etwa 60o bis etwa 120o liegen. Wesentlich ist in jedem Fal­le, daß Unterteil, Deckel und Federelement so ausgebildet sind, daß die Spritzform keine Trennwand oder Trennwände zwischen Unterteil 1 und Deckel 3 hat und daß der fertige Verschluß im Anschluß an den Spritzvor­gang ohne Schwierigkeiten in einer Richtung etwa lotrecht in Figur 2 entformt werden kann.Depending on the external shape of the closure, the spring element 14 can be curved (FIG. 2) or angled (FIG. 3). The angle can range from about 60 o to about 120 o . It is essential in any case that the lower part, cover and spring element are designed so that the injection mold has no partition or partitions between the lower part 1 and cover 3 and that the finished closure following the spraying process without difficulties in one direction approximately perpendicular in FIG. 2 can be demolded.

Dies wird insbesondere dadurch erreicht, daß Deckel und Unterteil Schrägränder der beschriebenen Anordnung haben. Eine Folge davon ist z.B., daß ein Deckel mit ebenem Boden 4 nach Figur 1 und 2, ebenso wie ein Deckel mit einwärts gewölbtem Boden, in Offenstellung oberhalb der Hauptdrehachse 10 liegt, während derartige Deckel nach dem Stand der Technik zumindest teilweise unterhalb der Filmscharniere liegen müssen.This is achieved in particular in that the cover and lower part have sloping edges of the arrangement described. One consequence of this is, for example, that a lid with a flat bottom 4 according to FIGS. 1 and 2, like a lid with an inwardly curved bottom, lies in the open position above the main axis of rotation 10, while such lids according to the prior art are at least partially below the film hinges have to.

Figur 4 zeigt eine spezielle Ausbildung der beiden Schrägflächen. Sie enthalten nämlich zueinander passende Stufen in der Rückwand 2 und im Boden 4 des Deckels. Am Deckel ist ein vorspringender Abschnitt 26 vor­gesehen. Er erhebt sich in Form einer Stufe mit stumpfwinkligen Kanten aus dem Schrägrand 24. Am Unterteil 2 ist ein zurückspringender Ab­schnitt 28 vorgesehen, der ebenfalls stumpfwinklig in den Schrägrand 22 übergeht und zum vorspringenden Abschnitt 26 paßt.Figure 4 shows a special design of the two inclined surfaces. Namely, they contain matching steps in the rear wall 2 and in the bottom 4 of the lid. A projecting section 26 is provided on the cover. It rises in the form of a step with obtuse-angled edges from the oblique edge 24. A recessed section 28 is provided on the lower part 2, which also transitions into the oblique edge 22 at an obtuse angle and fits the protruding section 26.

Beim Schließen des Deckels greift der vorspringende Abschnitt 26 in den zurückspringenden 28 ein, so daß die Stufen, mit denen beide in die Schrägränder übergehen, und die in Figur 5 lotrecht verlaufen, sich an­einander legen. Der Deckel wird hierdurch einwärts gezogen, so daß kein Abschnitt des Filmscharniers 8 mehr nach außen vorsteht.When the lid is closed, the projecting section 26 engages in the recessed 28, so that the steps with which both pass into the sloping edges and which run perpendicularly in FIG. 5 lie against one another. This pulls the lid inwards so that no section of the film hinge 8 protrudes outward.

Wie Figur 6 und 7 zeigen, kann das Filmscharnier auch als Bändchen 30 ausgebildet sein. Es soll dafür gesorgt werden, daß die Hauptschwenkach­se 10 an der durch ein Kreuz gekennzeichnenden Stelle liegt, also, bis auf Toleranzen, mit dem einen Rand des Bändchens zusammenfällt. Dies wird dadurch erreicht, daß der Deckel, ebenso wie in Figur 2 und 3, praktisch über seine volle Dicke (genauer gesagt über seine Dicke abzüg­lich der Dicke des Bändchens) einen Schrägrand 24a hat. Dagegen hat die Rückwand 2 des Unterteils nur einen verkürzten Schrägrand 22a, der sich an der Innenseite der Rückwand befindet, sowie eine quer zur Rückwand verlaufende Randfläche 32. Das Bändchen setzt mit seinem linken Rand an der Ecke zwischen Randfläche 32 und Außenfläche 2a der Rückwand an. Der in Figur 6 rechte Rand des Bändchens setzt an der Außenfläche 4a des Deckelbodens und am unteren Rande des Schrägrandes 24a an. Beim Schlie­ßen des Deckels legen sich die Schrägränder 22a und 24a aneinander (Fig. 7), wodurch das Bändchen 30 vollständig einwärts gezogen wird. Es steht also dann kein Abschnitt des Bändchens in Schließstellung nach au­ßen vor.As FIGS. 6 and 7 show, the film hinge can also be designed as a ribbon 30. It should be ensured that the main pivot axis 10 lies at the point marked by a cross, that is, with the exception of tolerances, coincides with one edge of the ribbon. This is achieved in that the lid, as in FIGS. 2 and 3, has a sloping edge 24a practically over its full thickness (more precisely over its thickness minus the thickness of the ribbon). In contrast, the rear wall 2 of the lower part has only a shortened inclined edge 22a, which is located on the inside of the rear wall, and an edge surface 32 running transversely to the rear wall . The right edge of the ribbon in FIG. 6 attaches to the outer surface 4a of the lid base and to the lower edge of the inclined edge 24a. When the lid is closed, the inclined edges 22a and 24a lie against one another (FIG. 7), as a result of which the ribbon 30 is pulled completely inwards. No section of the ribbon then protrudes outwards in the closed position.

Wie die Figuren 8 und 9 zeigen, ist die Erfindung auch auf Verschlüsse mit gekrümmten Außenwandungen anwendbar. Dort handelt es sich um Kegel mit elliptischen Querschnitten. Wichtig ist lediglich, daß der Unterteil im Bereich des Scharniers einen ebenen Abschnitt 34 hat, dessen Breite mindestens so groß ist wie die Gesamtlänge des Scharniers in Richtung der Hauptdrehachse 10. Vom Boden 20 des Unterteils ragen zwei Vorsprünge 36 nach oben, die je einen Schrägrand 22b der beschriebenen Art haben und durch je ein in die Hauptdrehachse 10 fallendens Filmscharnier 8 mit einem Schrägrand 24b des Deckels verbunden sind. Diese Schrägränder 24b verlaufen über die gesamte Dicke des Deckelbodens 4b, ähnlich wie es in Figur 3 dargestellt ist. Der Boden 4b des Deckels hat, bis auf die Länge des Scharniers, eine umlaufende Einfassung 38. In Schließstellung nach Figur 8 legt sich der untere Rand der Einfassung 38 auf den Boden 20 des Unterteils, während die Schrägränder 22b und 24b aufeinander liegen.As FIGS. 8 and 9 show, the invention is also applicable to closures with curved outer walls. There are cones with elliptical cross sections. It is only important that the lower part in the area of the hinge has a flat section 34, the width of which is at least as large as the total length of the hinge in the direction of the main axis of rotation 10. Two projections 36 protrude from the bottom 20 of the lower part, each of which has a sloping edge 22b of the type described and are each connected to a sloping edge 24b of the cover by a film hinge 8 falling into the main axis of rotation 10. These inclined edges 24b run over the entire thickness of the lid base 4b, similar to that shown in FIG. 3. The bottom 4b of the lid has up to the length of the hinge, a circumferential border 38. In the closed position according to FIG. 8, the lower edge of the border 38 lies on the bottom 20 of the lower part, while the oblique edges 22b and 24b lie on one another.

Die Schrägflächen 22 und 24 können, wie besonders gut in Figur 3 darge­stellt, eben sein. Sie können aber auch gekrümmt sein, nämlich Mantel­flächen parallel zur Hauptdrehachse haben. Die Krümmungen sollten dann vorzugsweise in Schließstellung ineinander passen.As particularly well shown in FIG. 3, the inclined surfaces 22 and 24 can be flat. But they can also be curved, namely have lateral surfaces parallel to the main axis of rotation. The curvatures should then preferably fit into one another in the closed position.

Die Erfindung ist auch anwendbar auf Verschlüsse, bei denen nur ein ein­ziges Filmscharnier in der Mitte angeordnet ist, das von zwei Federele­menten flankiert wird.The invention is also applicable to closures in which only a single film hinge is arranged in the middle, which is flanked by two spring elements.

Die Erfindung ist auch auf Anordnungen anwendbar, bei denen mehr als zwei Federelemente und/oder Filmscharniere in der Hauptdrehachse neben­einander angeordnet sind, was z.B. bei Schachteln erforderlich sein kann.The invention is also applicable to arrangements in which more than two spring elements and / or film hinges are arranged side by side in the main axis of rotation, which e.g. may be necessary for boxes.

Falls notwendig können die Verschlüsse auch nach herkömmlicher Art in Formen mit Backen oder Schiebern gespritzt und dann entsprechend ent­formt werden.If necessary, the closures can also be molded in a conventional manner into molds with jaws or sliders and then demolded accordingly.
