Abstract

A hinge apparatus is disclosed, in which at least two flexible strips (1-3) are articulated, each via two articulation grooves (7, 8), to two parts (5, 6) that are movable relative to one another and are substantially cylindrical in embodiment, in such a manner that upon a relative movement of the two parts with respect to one another out of one stable position into the other stable position, the flexible strips are located in a substantially radial plane of the two parts (FIG. 3a).

Description

Die Erfindung bezieht sich auf einen Behälterverschluß mit zwei relativ zueinander beweglichen, im wesentlichen zylindrischen, konzentrischen Teilen, die über ein Element derart miteinander verbunden sind, daß sie bei ihrer Relativbewegung eine Totpunktlage überwinden müssen, um eine von zwei möglichen stabilen Stellungen einnehmen zu können, von denen eine die Offen- und die andere die Schließstellung des Behälterverschlusses ist.The invention relates to a container closure with two relatively cylindrical, concentric parts which are movable relative to one another and which are connected to one another via an element such that they have to overcome a dead center position in order to be able to assume one of two possible stable positions, one of which is the open and the other the closed position of the container closure.

Bei einem solchen, aus der US-A-1 959 206 bekannten Behälterverschluß für Dosen od. dgl. sind die beiden relativ zueinander beweglichen Teile kuppelförmig ausgebildet. Der innere kuppelförmige Teil ist ortsfest am Behälterverschluß bzw. der Dose befestigt. Der zu diesem ortsfesten Teil relativ bewegliche äußere kuppeiförmige Teil ist mit Hilfe einer das Element bildenden elastischen Federscheibe an dem ortsfesten Teil derart beweglich gelagert, daß der Innenumfangsrand der Federscheibe in eine an dem ortsfesten Teil vorgesehene Ringnut eingreift, während der äußere Umfangsrand in eine an einer Auskragung des äußeren Teils vorgesehene innere Ringnut eingreift. Diese Federscheibe hat dabei solche Abmessungen, daß sie sich nur dann in einer ebenen Lage befindet, wenn die beiden Ringnuten sich nicht in einer gemeinsamen horizontalen Ebene befinden, da der radiale Abstand der beiden Ringnuten in einer gemeinsamen horizontalen Ebene am geringsten ist. In der geschlossenen Stellung des Behälterverschlusses, in der das äußere kuppelförmige Teil am inneren kuppelförmigen Teil anliegt, befindet. sich die Ringnut des äußeren Teils in einer horizontalen Ebene, die niedriger als die horizontale Ebene der Ringnut des inneren Teils liegt. In der Offenstellung des Behälterverschlusses befindet sich die Ringnut des äußeren Teils dagegen in einer horizontalen Ebene, die oberhalb der der Ringnut des inneren Teils liegt. In dieser Offenstellung des Behälterverschlusses sind im inneren Teil und im äußeren Teil jeweils vorgesehene Öffnungen von zugeordneten Teilen des inneren Teils sowie des äußeren Teils nicht länger verdeckt, so daß ein in der Dose befindlicher Inhalt durch die im Behälterverschluß vorgesehenen Öffnungen hindurch austreten kann. Da sich die Federscheibe beim Übergang des Behälterverschlusses aus seiner Offenstellung in seine Schließstellung infolge des geringen Abstandes zwischen den beiden Ringnuten aufwölben muß, ist eine solche Übergangsstellung nicht stabil, so daß der Behälterverschluß je nach Kraftaufwendung immer nur eine seiner beiden stabilen Stellungen, d. h. die Schließstellung oder die Offenstellung, einnehmen kann. Bei diesem bekannten Behälterverschluß sind alle Teile, d. h. sowohl die Federscheibe als auch die inneren und äußeren kuppelförmigen Teile, aus Metallblech gefertigt. Dieser bekannte Behälterverschluß erfordert daher einen erheblichen Fertigungsaufwand. Außerdem muß das Metallblech aus einem entsprechend teuren, korrosionsfreien Material bestehen, wenn der Behälterverschluß nicht infolge von Korrosionserscheinungen bereits nach relativ kurzer Zeit unansehnlich und funktionsunfähig werden soll.In such a container closure for cans or the like, which is known from US Pat. No. 1,959,206, the two parts which are movable relative to one another are dome-shaped. The inner dome-shaped part is fixed in place on the container closure or the can. The relatively dome-shaped part which is relatively movable to this stationary part is mounted so that it can move with the aid of an elastic spring washer forming the element on the stationary part in such a way that the inner peripheral edge of the spring washer engages in an annular groove provided on the stationary part, while the outer peripheral edge engages in one on one Cantilever of the outer part engages provided inner annular groove. This spring washer has dimensions such that it is only in a flat position when the two ring grooves are not in a common horizontal plane, since the radial distance between the two ring grooves is the smallest in a common horizontal plane. In the closed position of the container closure, in which the outer dome-shaped part rests on the inner dome-shaped part. the annular groove of the outer part in a horizontal plane which is lower than the horizontal plane of the annular groove of the inner part. In the open position of the container closure, however, the annular groove of the outer part is in a horizontal plane which lies above that of the annular groove of the inner part. In this open position of the container closure, the openings provided in the inner part and in the outer part are no longer covered by associated parts of the inner part and the outer part, so that contents in the can can escape through the openings provided in the container closure. Since the spring washer must bulge out of its open position into its closed position due to the small distance between the two ring grooves during the transition of the container closure, such a transition position is not stable, so that the container closure always only one of its two stable positions, depending on the application of force. H. can take the closed position or the open position. In this known container closure, all parts, i.e. H. Both the spring washer and the inner and outer dome-shaped parts, made of sheet metal. This known container closure therefore requires considerable manufacturing effort. In addition, the metal sheet must consist of a correspondingly expensive, corrosion-free material if the container closure is not to become unsightly and inoperable after a relatively short time as a result of corrosion phenomena.

Andererseits sind Scharniergelenkanordnungen aus Kunststoff aus der DE-C-19 09 405 in Verbindung mit einem Kleiderbügel bekannt, wobei die ersten und zweiten Teile zwischen sich Klemmflächen bilden, um ein Kleidungsstück in dem Kleiderbügel festklemmen zu können. Eine vergleichbare Scharniergelenkanordnung ist auch z. B. aus der DE-A-24 59 628 in Verbindung mit einem Flaschenverschluß bekannt, wobei das erste Teil die Verschlußkappe und das zweite Teil ein über die zwei federstreifen mit der Verschlußkappe verbundener Verriegelungsring ist, der diese im verschlossenen Zustand an einer einem Scharnier diametral gegenüberliegenden Stelle gegen das Flaschenoberteil drückt.On the other hand, hinge joint arrangements made of plastic are known from DE-C-19 09 405 in connection with a clothes hanger, the first and second parts forming clamping surfaces between them in order to be able to clamp a garment in the clothes hanger. A comparable hinge arrangement is also z. B. from DE-A-24 59 628 in connection with a bottle cap known, the first part of the cap and the second part is a locking ring connected to the two spring strips with the cap, which diametrically in the closed state on a hinge opposite point presses against the bottle top.

Aufgabe der Erfindung ist es, einen Behälterverschluß der im Oberbegriff des Anspruchs 1 genannten Art so weiterzubilden, daß er in einfacher Weise vollständig aus Kunststoff herstellbar und über relativ lange Betriebsdauern funktionszuverlässig ist.The object of the invention is to develop a container closure of the type mentioned in the preamble of claim 1 in such a way that it can be produced completely from plastic in a simple manner and is functionally reliable over relatively long operating times.

Bei einem Behälterverschluß der genannten Art ist diese Aufgabe dadurch gelöst, daß der Behälterverschluß einstückig aus Kunststoff ausgebildet ist und daß mindestens zwei Federstreifen das Element bilden und an einander etwa diametral gegenüberliegenden Umfangsseiten des ersten Teils und an dem zweiten Teil jeweils über zwei Gelenkrillen derart angelenkt sind, daß in der Totpunktlage der beiden Teile die beiden Gelenkrillen eines jeden Federstreifens jeweils in einer im wesentlichen radialen gemeinsamen Schnittebene der beiden Teile liegen, wobei die Gelenkrillen im wesentlichen parallel oder schräg zur Zylinderlängsebene der beiden Teile angeordnet sind.With a container closure of the type mentioned, this object is achieved in that the container closure is formed in one piece from plastic and in that at least two spring strips form the element and are articulated in such a way on approximately diametrically opposite circumferential sides of the first part and on the second part via two joint grooves that in the dead center position of the two parts, the two joint grooves of each spring strip each lie in a substantially radial common sectional plane of the two parts, the joint grooves being arranged essentially parallel or obliquely to the longitudinal plane of the cylinder of the two parts.

Der erfindungsgemäße Behälterverschluß ist also aus Kunststoff gefertigt, so daß er in sehr einfacher Weise einstückig aus Kunststoff gespritzt werden kann. Dieser Behälterverschluß ist korrosionsbeständig und hat außerdem infolge seiner hohen Elastizität eine lange Lebensdauer auch gegenüber mechanischen Beanspruchungen, da die die Scharniere bildenden Gelenkrillen eine sehr hohe Zahl von Scharnierspielen ausführen können, ohne daß sie brechen.The container closure according to the invention is thus made of plastic, so that it can be injection molded in one piece from plastic in a very simple manner. This container closure is corrosion-resistant and, due to its high elasticity, also has a long service life, even under mechanical stress, since the hinge grooves forming the hinges can carry out a very large number of hinge games without breaking.

In den Fig.la bis 1e sind schematisch im Schnitt bzw. von oben jeweils verschiedene Ausführungsformen eines ersten Ausführungsbeispiels dargestellt, bei denen Federstreifen 1 und 2 jeweils über hier nicht näher dargestellte Gelenkrillen 7, 8 (vgl. Fig.2c und 2d) zwischen einem ersten zylindrischen Teil 5 und einem zweiten zylindrischen Teil 6 vorgesehen sind. Die Gelenkrillen verlaufen dabei jeweils im wesentlichen parallel zur Zylinderlängsachse der beiden Teile 5 und 6. Bei allen Ausführungsformen ist der jeweils erste oder innere Teil 5 in einer ersten stabilen Stellung der beiden Teile mit durchgezogenen Linien dargestellt, während der erste Teil 5 in seiner zweiten stabilen Stellung gestrichelt dargestellt ist. Wie aus den einzelnen Darstellungen leicht zu erkennen ist, durchlaufen die beiden Teile 5 und 6 bei ihrer Relativbewegung von der einen stabilen Stellung in die jeweils andere eine Totpunktlage, bei der die Gelenkrillen eines jeden Federstreifens 1 und 2 jeweils in einer gemeinsamen radialen Ebene der beiden Teile 5 und 6 liegen. Dieses ist dabei unabhängig davon, ob die Federstreifen 1 und 2, wie in den Fig. 1a und 1e gezeigt ist, z. B. 'steif oder aber, wie es in den Fig.1 gezeigt ist, beide elastisch ausgebildet sind. Sind beide Federstreifen 1 und 2 oder zumindest einer von ihnen, wie es in den Fig. 1c und 1 gezeigt ist, elastisch ausgebildet, so können die beiden Teile 5 und 6 im wesentlichen unelastisch ausgebildet sein, da dann die erforderliche Verkürzung des Abstandes zwischen den Gelenkrillen eines jeden Federstreifens durch die Federstreifen selbst bewirkt oder aufgenommen wird. Sind dagegen beide Federstreifen 1 und 2 im wesentlichen unelastisch ausgebildet, so muß mindestens eines der Teile 5 oder 6, vorzugsweise das äußere Teil 6, elastisch in Form einer Bogenfeder ausgebildet sein, um den dann unveränderten Abstand zwischen den Gelenkrillen beim Hindurchlaufen der radialen Ebene durch die Gelenkrillen aufnehmen bzw. ausgleichen zu können. Wie aus den einzelnen Figuren zu erkennen ist, führen die beiden Teile 5 und 6 eine reine Längsbewegung oder aber eine aus einer Längs- und Drehbewegung zusammengesetzte Relativbewegung aus. Bei einer solchen Relativbewegung ist es unerheblich, ob das erste oder zweite Teil jeweils als stationär oder beweglich angesehen wird oder aber beide Teile nicht nur eine Relativbewegung zueinander sondern auch gegenüber einem stationären Ort ausführen. Bei einem in den Fig. 2a bis 2d gezeigten praktischen Anwendungsbeispiel des in Fig. 1 gezeigten Ausführungsbeispiels ist das erste oder innere Teil 5 durch das Öffnungsteil einer Tube oder dgl. gebildet, während das zweite oder äußere Teil 6 als eine etwa ellipsenförmig geformte Abdeckkappe ausgebildet ist. Wie es in den Fig.2a und 2b gezeigt ist, ist die Form der Abdeckkappe dabei in weiten Grenzen beliebig, um z. B. eine manuell beaufschlagbare Angriffsfläche zu bilden, solange das erste Teil 5 innerhalb des zweiten Teils 6 eine ausreichende Bewegungsfreiheit hat, um die zwei möglichen stabilen Stellungen einnehmen zu können.In FIGS. 1 to 1e, different embodiments of a first exemplary embodiment are shown schematically in section or from above, in which spring strips 1 and 2 each have an articulated groove 7, 8 (cf. FIGS. 2c and 2d), not shown here, between one first cylindrical part 5 and a second cylindrical part 6 are provided. The joint grooves each run essentially parallel to the longitudinal axis of the two parts 5 and 6. In all embodiments, the first or inner part 5 is shown in a first stable position of the two parts with solid lines, while the first part 5 in its second stable Position is shown in dashed lines. As can easily be seen from the individual representations, the two parts 5 and 6 pass through a dead center position in their relative movement from one stable position to the other, in which the joint grooves of each spring strip 1 and 2 each in a common radial plane of the two Parts 5 and 6 lie. This is regardless of whether the spring strips 1 and 2, as shown in FIGS. 1a and 1e, z. B. 'stiff or, as shown in Fig.1, both are elastic. If both spring strips 1 and 2 or at least one of them, as shown in FIGS. 1c and 1, are designed to be elastic, then the two parts 5 and 6 can be made essentially inelastic, since then the required shortening of the distance between the Articulated grooves of each spring strip is effected or recorded by the spring strips themselves. If, on the other hand, both spring strips 1 and 2 are essentially inelastic, at least one of the parts 5 or 6, preferably the outer part 6, must be designed elastically in the form of an arc spring in order to maintain the then unchanged distance between the joint grooves when passing through the radial plane to be able to absorb or compensate for the joint grooves. As can be seen from the individual figures, the two parts 5 and 6 perform a purely longitudinal movement or a relative movement composed of a longitudinal and rotary movement. With such a relative movement, it is irrelevant whether the first or second part is in each case regarded as stationary or movable or whether both parts not only perform a relative movement to one another but also to a stationary location. In a practical application example shown in FIGS. 2a to 2d of the embodiment shown in FIG. 1, the first or inner part 5 is formed by the opening part of a tube or the like, while the second or outer part 6 is designed as an approximately elliptically shaped cover cap is. As shown in FIGS. 2a and 2b, the shape of the cover cap is arbitrary within wide limits in order, for. B. to form a manually actable attack surface, as long as the first part 5 within the second part 6 has sufficient freedom of movement to be able to assume the two possible stable positions.

Die Abdeckkappe 6 ist mit einer in den Fig. 2a und 2b gezeigten Öffnung versehen, um in der in Fig.2a gezeigten ersten stabilen Stellung den Öffnungsteil 5 einer Tube freizugeben, und bei der in Fig. 2b gezeigten Stellung den Öffnungsteil 5 der Tube dichtend zu verschließen.The cover cap 6 is provided with an opening shown in FIGS. 2a and 2b in order to expose the opening part 5 of a tube in the first stable position shown in FIG. 2a and in the position shown in FIG. 2b sealing the opening part 5 of the tube to close.

In den Fig. 2c und 2d sind wiederum schematisch jeweils die beiden stabilen Stellungen der beiden Teile 5 und 6 dargestellt, wobei die Gelenkrillen 7 und 8 eines jeden Federstreifens 1 und 2 in der zwischen diesen stabilen Stellungen liegenden Totpunktlage beider Teile wiederum jeweils gemeinsam in einer im wesentlichen radialen Ebene der Teile 5 und 6 liegen.2c and 2d, the two stable positions of the two parts 5 and 6 are again shown schematically, the articulated grooves 7 and 8 of each spring strip 1 and 2 in the dead center position between these parts lying between these stable positions again in each case together in one lie essentially in the radial plane of parts 5 and 6.

In Fig. 3a ist ein weiteres Ausführungsbeispiel der Erfindung schematisch dargestellt, wobei drei Federstreifen 1, 2 und 3 in der dort gezeigten einen stabilen Stellung der beiden Teile 5 und 6 etwa radspeichenartig zwischen diesen beiden Teilen liegen. Alle Federstreifen 1 bis 3 sind wiederum in hier nicht näher dargestellter Weise jeweils über Gelenkrillen 7 und 8 mit den ersten und zweiten Teilen 5 und 6 verbunden. Auch bei diesem Ausführungsbeispiel erstrecken sich alle Gelenkrillen 7 und 8 aller Federstreifen im wesentlichen parallel zur Zylinderlängsachse der beiden Teile 5 und 6.In Fig. 3a, another embodiment of the invention is shown schematically, wherein three spring strips 1, 2 and 3 in the one position shown there are a stable position of the two parts 5 and 6 approximately like a wheel spoke between these two parts. All spring strips 1 to 3 are in turn connected to the first and second parts 5 and 6 in a manner not shown here in each case via joint grooves 7 and 8. In this exemplary embodiment, too, all of the joint grooves 7 and 8 of all the spring strips extend substantially parallel to the longitudinal axis of the two parts 5 and 6.

Um die beiden Teile 5 und 6 in ihre jeweils andere stabile Stellung zu bringen, müssen sie relativ zueinander verdreht werden, wobei dann die Federstreifen 1 bis 3 und insbesondere ihre jeweiligen Gelenkrillen 7 und 8 die Totpunktlage durchlaufen, bei der sich die Gelenkrillen jeweils in einer radialen Ebene der beiden Teile 5 und 6 befinden.In order to bring the two parts 5 and 6 into their respective other stable positions, they must be rotated relative to one another, in which case the spring strips 1 to 3 and in particular their respective joint grooves 7 and 8 pass through the dead center position, in which the joint grooves are each in one radial plane of the two parts 5 and 6 are located.

Sind die Federstreifen 1 bis 3 in der hier angedeuteten Weise im wesentlichen steif, d. h. unelastisch, ausgebildet, so muß mindestens eines der Teile 5 und 6, vorzugsweise das zweite Tei16, elastisch ausgebildet sein, um in der Totpunktlage den steifen Federstreifen 1 bis 3 ausweichen zu können.Are the spring strips 1 to 3 in the manner indicated here essentially stiff, d. H. Inelastic, designed, at least one of the parts 5 and 6, preferably the second part 16, must be designed to be elastic in order to be able to avoid the stiff spring strips 1 to 3 in the dead center position.

In Fig. 3b ist ein ähnliches Ausführungsbeispiel der Erfindung schematisch dargestellt, bei dem jedoch vier Federstreifen 1 bis 4 zwischen den beiden Teilen 5 und 6 gleichmäßig über deren Umfang verteilt vorgesehen sind. Hier sind die Federstreifen 1 bis 4 elastisch, d. h. bogenförmig ausgebildet, so daß die beiden Teile 5 und 6 unelastisch ausgebildet sein können. In der Totpunktlage rücken daher die Gelenkrillen 7 und 8 eines jeden Federstreifens 1 bis 4 aufeinander zu, um ihren gegenseitigen Abstand auf den jeweiligen radialen Abstand zwischen den beiden Teilen 5 und 6 zu verkürzen.In Fig. 3b a similar embodiment of the invention is shown schematically, but in which four spring strips 1 to 4 are provided between the two parts 5 and 6 evenly distributed over their circumference. Here the spring strips 1 to 4 are elastic, i.e. H. arcuate, so that the two parts 5 and 6 can be inelastic. In the dead center position, the articulated grooves 7 and 8 of each spring strip 1 to 4 move towards one another in order to shorten their mutual distance to the respective radial distance between the two parts 5 and 6.

Auch bei diesem Ausführungsbeispiel findet wiederum eine Relativdrehung zwischen den beiden Teilen 5 und 6 zwischen zwei stabilen Drehstellungen statt, wobei jeweils die Totpunktlage beider Teile 5 und 6 durchlaufen werden muß. Auch diese Ausführungsbeispiele können z. B. in Form von Verschlüssen bei Behältern angewendet werden, bei denen in den unterschiedlichen stabilen Stellungen der beiden Teile 5 und 6 z. B. Öffnungsschlitze, wie z. B. bei Streubüchsen, freigegeben und abgedeckt werden.In this embodiment too, there is again a relative rotation between the two parts 5 and 6 between two stable rotational positions, the dead center position of both parts 5 and 6 having to be passed through. These embodiments can, for. B. in the form of closures for containers in which in the different stable positions of the two parts 5 and 6 z. B. opening slots such. B. with spreader boxes, released and covered.

Ein weiteres Ausführungsbeispiel ist in 4 schematisch gezeigt, bei dem die Federstreifen zwischen den beiden.Teilen 5 und 6 über Gelenkrillen 7 und 8 jeweils so an den beiden Teilen angelenkt sind, daß die Gelenkrillen 7 und 8 sowohl eine in Kreisumfangsrichtung gerichtete als auch eine im wesentlichen parallel zur Zylinderlängsachse angeordnete Richtungskomponente haben. Die einzelnen Federstreifen sind daher sowohl, wie es z. B. in Fig. 3a gezeigt ist, in den stabilen Stellungen der beiden Teile 5 und 6 in Kreisumfangsrichtung aus der Radialebene als auch in Vertikalrichtung aus einer Querebene der Zylinder herausgeneigt.A further exemplary embodiment is shown schematically in FIG. 4, in which the spring strips between the two parts 5 and 6 are articulated on the two parts via joint grooves 7 and 8 in such a way that the joint grooves 7 and 8 are directed both in the circumferential direction and in the have direction components arranged substantially parallel to the longitudinal axis of the cylinder. The individual feather strips are therefore both, as z. As shown in Fig. 3a, in the stable positions of the two parts 5 and 6 inclined in the circumferential direction from the radial plane and in the vertical direction from a transverse plane of the cylinders.

Bei der Relativbewegung der beiden Teile 5 und 6 aus ihrer einen stabilen Stellung in die jeweils andere stabile Stellung findet sowohl eine Relativdrehung als auch eine Retatiwerschiebung in einer senkrecht zum Drehradius gerichteten Richtung statt, wobei in der Totpunktlage der beiden Teile 5 und 6 die beiden Gelenkrillen 7 und 8 eines jeden Federstreifens 1 bis 4 wiederum sowohl in der Querebene als auch einer Radialebene der Zylinder liegen müssen.During the relative movement of the two parts 5 and 6 from their one stable position to the other stable position, both a relative rotation and a retinal displacement take place in a direction perpendicular to the turning radius, with the two joint grooves in the dead center position of the two parts 5 and 6 7 and 8 of each spring strip 1 to 4 must in turn lie both in the transverse plane and in a radial plane of the cylinders.

Auch dieses Ausführungsbeispiel kann z. B. bei Verschlüssen von Behältern angewendet werden, um z. B. an der Mantelfläche des zweiten Teils 6 und/oder der Stirnfläche des ersten Teils 5 vorgesehene Streuöffnungen od. dgl. in der einen stabilen Stellung zu öffnen und in der anderen stabilen Stellung jeweils zu verschließen.This embodiment can also, for. B. applied to closures of containers, for. B. on the lateral surface of the second part 6 and / or the end face of the first part 5 provided scatter openings or the like. Open in one stable position and close each in the other stable position.

Claims (7)

1. Container closure comprising two substantially cylindrical parts (5, 6), movable relative to each other, which are connected together by an element (1 to 4) in such a manner that they must overcome a dead-centre position in their relative movement, in order to adopt one of two possible stable positions, one of which is the open position and the other the closed position of the container closure, characterized in that the container closure is formed in one piece of plastics material and that at least two spring strips (1, 2, 3, 4) constitute the element and are each articulated by two hinge grooves (7, 8) to peripheral faces of the first part (5) and of the second part (6) lying generally diametrally opposite to each other, in such a manner that, in the dead-centre position of the two parts, the two hinge grooves (7, 8) of each spring strip (1 to 4) lie in a substantially radial common section plane of the two parts (5, 6), the hinge grooves (7, 8) being disposed parallel to or oblique to the cylinder longitudinal axis of the two parts (5, 6).
2. Container closure according to Claim 2, characterized in that two spring strips (1, 2) are disposed with their hinge grooves (7, 8) substantially parallel to the cylinder longitudinal axis of the two parts (5, 6), and that the first part (5) is an opening component of a tube or the like and the second part (6) is a substantially circular or elliptical cover cap, which possesses an opening (9) which is aligned with the opening component (5) in the one stable position and sealingly closes this opening component in the other stable position (Figures 2a to 2d).
3. Container closure according to Claim 1, characterized in that three or more spring strips (1 to 4) are disposed between the first part (5) and the second part (6), uniformly distributed around their circumference (Figures 3, 4).
4. Container closure according to Claim 3, characterized in that the hinge grooves (7, 8) of all the spring strips (1 to 4) have a directional component disposed parallel to the longitudinal axis and a directional component extending in the circumferential direction, with the result that the relative movement between the two parts (5, 6) consists of a relative rotational movement and of a relative longitudinal movement perpendicular to the axis of rotation (Figure 4).
5. Container closure according to one of Claims 1 to 4, characterized in that the spring strips (1 to 4) are of stiff construction and the two parts (5, 6) are of elastic construction, in order to produce the forces necessary for reaphing and maintaining the two stable positions.
