Description

Die Erfindung betrifft einen Verschluß für Flaschen gemäß dem Oberbegriff des vorstehenden Hauptanspruchs.The invention relates to a closure for bottles according to the preamble of the preceding main claim.

Verschlüsse dieser Art werden in vielen Ländern millionenfach hergestellt und für alle möglichen Flaschen, beispielsweise für Putzmittel und Kosmetika, verwendet. Bei diesen Verschlüssen wird der Deckel durch den Federstreifen in zwei möglichen stabilen Lagen festgehalten, nämlich in einer geöffneten Lage und in einer Lage .kurz vor der Verschließstellung.Closures of this type are manufactured millions of times in many countries and used for all kinds of bottles, for example for cleaning agents and cosmetics. With these closures, the cover is held in two possible stable positions by the spring strip, namely in an open position and in one position . shortly before the closed position.

Ein Nachteil dieser Verschlüsse besteht darin, daß der Deckel zwar mit einem Handgriff geöffnet werden kann, daß aber zum Schließen zwei Handgriffe erforderlich sind. Die geometrischen Verhältnisse bei den bisher bekannten Verschlüssen sind nämlich so, daß der Federstreifen beim Schließen seine Spannung bereits verliert, bevor der Deckel völlig geschlossen ist. Es ist deshalb üblich, Verschlüsse dieser Art mit einem Schnappverschluß zu versehen, der nach dem Umkippen des Deckels in die Verschlußstellung erst durch weiteres Zudrücken des Deckels zur Einrastung kommt.A disadvantage of these closures is that the lid can be opened with a handle, but that two handles are required to close. The geometrical relationships in the closures known to date are such that the spring strip loses its tension when it is closed before the lid is completely closed. It is therefore customary to provide closures of this type with a snap lock which, after the lid has tipped over into the closed position, only comes into engagement by further pressing the lid.

Der Erfindung lag die Aufgabe zugrunde, Verschlüsse der in Rede stehenden Art so weiterzubilden, daß sie diesen Nachteil nicht aufweisen und daß der Deckel nach dem Überschnappen über den Totpunkt automatisch in die Verschlußstellung gelangt und dabei gegebenenfalls auch einen Schnappverschluß zum Einrasten bringt.The invention had for its object to develop closures of the type in question so that they do not have this disadvantage and that the cover automatically comes into the closed position after snapping over the dead center and, if necessary, also brings a snap lock into place.

Die Aufgabe wird gemäß der Erfindung dadurch gelöst, daß bei einem solchen Verschluß in geöffnetem Zustand des Deckels und bei entspanntem Federstreifen der Winkel (Winkel α) zwischen der Geraden durch die Anlenkpunkte FD und DK und der Geraden G größer ist als der entsprechende Winkel im geschlossenen Zustand des Deckels (Winkel ß).The object is achieved according to the invention in that, with such a closure in the open state of the cover and with the spring strip relaxed, the angle (angle α) between the straight line through the articulation points FD and DK and the straight line G is greater than the corresponding angle in the closed position Condition of the cover (angle ß).

Damit ein solcher Deckel auch sicher zugehalten wird und damit gegebenenfalls auch ein Schnappverschluß zum Einrasten gebracht werden kann, soll der Winkel α mindestens 5°, insbesondere mindestens 10° und vorzugsweise mindestens 20° größer sein als der Winkel ß.So that such a cover is also held securely and thus a snap lock can also be snapped into place, the angle α should be at least 5 °, in particular at least 10 ° and preferably at least 20 ° larger than the angle β.

Üblicherweise werden solche Verschlüsse auf Kunststoffspritzmaschinen hergestellt, die es erforderlich machen, die Verschlüsse in der Weise herzustellen, daß sie nach dem Ausstoßen aus der Form den Deckel in einer um 180° geschwenkten Öffnungslage aufweisen, wobei natürlich dabei der Federstreifen auch in dieser Lage hergestellt ist und bei dieser Lage entspannt ist. Bei solchermaßen hergestellten Verschlüssen wird es bevorzugt, daß die Gerade G sich mit der Längsachse der Kappe über den Verschluß mit einem spitzen Winkel schneiden. Dieser spitze Winkel kann zur Erzielung einer ausreichenden Druckkraft des geschlossenen Deckels gegen die Kappe ca. 1 bis 20, insbesondere 5 bis 20 und bevorzugt 10 bis 20° betragen.Such closures are usually produced on plastic injection molding machines, which make it necessary to manufacture the closures in such a way that, after they have been ejected from the mold, they have the lid in an opening position pivoted by 180 °, the spring strip also being produced in this position, of course and is relaxed in this situation. In closures produced in this way, it is preferred that the straight line G intersect with the longitudinal axis of the cap over the closure at an acute angle. This acute angle can be approximately 1 to 20, in particular 5 to 20 and preferably 10 to 20 ° in order to achieve a sufficient compressive force of the closed cover against the cap.

Um solche geometrischen Verhältnisse zu erreichen, ist es am einfachsten, daß der Anlenkpunkt KF sich auf einem Vorsprung der Kappe befindet und von der Mittelachse der Kappe weiter entfernt ist als der Anlenkpunkt DK.In order to achieve such geometrical relationships, it is simplest that the articulation point KF is located on a projection of the cap and is further away from the central axis of the cap than the articulation point DK.

Weil bei dem erfindungsgemäßen Verschluß der Federstreifen stärker beansprucht ist und auch bei geschlossener Stellung des Deckels unter Spannung steht, wird es bevorzugt, diesen Federstreifen im mittleren Bereich mit einer Verstärkung auszubilden. Bei gebogenem Federstreifen kann die Form des Federstreifens etwa mondsichelförmig sein, während bei gewinkeltem Federstreifen die Verstärkung vorzugsweise in der Unterseite des Knies angeordnet ist.Die Verstärkungen sind deshalb im mittleren Bereich des Federstreifens angeordnet, weil dort beim Spannen des Federstreifens die stärksten Ausrichtkräfte herrschen.Because the spring strip in the closure according to the invention is subject to greater stress and is under tension even when the cover is in the closed position, it is preferred to provide this spring strip with a reinforcement in the central region. When the spring strip is bent, the shape of the spring strip can be roughly crescent-shaped, while when the spring strip is angled, the reinforcement is preferably arranged in the underside of the knee.

Bei den bekannten Verschlüssen besteht das Verschlußteil, welches die Ausgießöffnung der Kappe verschließt, üblicherweise aus einem Zapfen mit einem kleinen verdickten Köpfchen, wodurch gleichzeitig ein Schnappverschluß gebildet wird. Damit beim erfindungsgemäßen Verschluß das Zuschnappen des Deckels erleichtert wird, ist ein solcher in die Ausflußöffnung passender Zapfen vorzugsweise nicht in einer Form eines Köpfchens, sondern als leichter Konus ausgebildet. Da der Deckel beim erfindungsgemäßen Verschluß durch den Federstreifen in seiner Verschlußstellung festgehalten wird, ist es nicht nötig, daß der leicht konische Zapfen eine Hinterschneidung für die Einrastung in der Ausgießöffnung aufweist. Eine solche Hinterschneidung kann aber trotzdem gegebenenfalls vorgesehen werden.In the known closures, the closure part, which closes the pouring opening of the cap, usually consists of one Pin with a small thickened head, which also forms a snap lock. In order for the closure of the cover to be facilitated in the closure according to the invention, such a peg fitting into the outflow opening is preferably not in the form of a bowl, but rather as a light cone. Since the lid in the closure according to the invention is held in its closed position by the spring strip, it is not necessary for the slightly conical pin to have an undercut for engaging in the pouring opening. Such an undercut can still be provided if necessary.

Die Erfindung wird nun anhand der'Zeichnungen näher erläutert, in denen entsprechende Teile mit den gleichen Bezugszeichen beziffert sind.The invention will now be explained in more detail with reference to the drawings, in which corresponding parts are numbered with the same reference numerals.

  • Fig. 4 shows an embodiment of a closure according to the invention with the geometric conditions when closing the closure.

Der bekannte Verschluß wie auch der erfindungsgemäße Verschluß bestehen aus einer Kappe 1 mit einem inneren Schraubengewinde 2, das zum Aufschrauben auf eine Flasche dient. Die Kappe besitzt weiterhin eine Ausflußöffnung 3. Ein Deckel 4 ist über ein Federscharnier 5 am Anlenkpunkt DK am Rand der Kappe 1 angelenkt. Der Deckel weist in seiner Mitte eine Ausnehmung 6 auf, die auch das Federscharnier 5 unterteilt und für die Aufnahme eines gewinkelten Federstreifens 7 dient, welcher einerseits am Anlenkpunkt FD mittels eines Federscharniers 8 und andererseits am Anlenkpunkt mittels eines Federscharniers 9 angelenkt ist. Ein Verschlußteil 10 mit einem Köpfchen 11 am Deckel 4 schnappt in Verschließstellung in die Ausflußöffnung 3 ein und bildet dabei einen flüssigkeitsdichten Verschluß.The known closure as well as the closure according to the invention consist of a cap 1 with an internal screw thread 2, which is used for screwing onto a bottle. The cap also has an outflow opening 3. A cover 4 is articulated via a spring hinge 5 at the articulation point DK on the edge of the cap 1. The lid has a recess 6 in its center, which also divides the spring hinge 5 and serves to receive an angled spring strip 7, which on the one hand at the articulation point FD by means of a spring hinge 8 and on the other hand at the articulation point a spring hinge 9 is articulated. A closure part 10 with a bowl 11 on the lid 4 snaps into the outflow opening 3 in the closed position and thereby forms a liquid-tight closure.

Es ist aus Fig. 3 ersichtlich, daß bei dem bekannten Verschluß der Winkel OC zwischen der Geraden G, bei der sich der Deckel in der Umschnappstellung befindet, und der Geraden durch die Anlenkpunkte DK und FD bei geöffneter Stellung des Deckels nicht größer ist als der entsprechende Winkel ß bei geschlossener Stellung des Deckels. Dies hat zur Folge, daß der Deckel nach dem Umschnappen nur bis zur gestrichelt dargestellten Lage gelangt. Der Federstreifen hat in dieser Lage bereits seine Federkraft eingebüßt, so daß er nicht in der Lage ist, den Deckel vollständig in Verschlußstellung zu bringen.It can be seen from Fig. 3 that in the known closure the angle OC between the straight line G, in which the cover is in the snap-in position, and the straight line through the articulation points DK and FD when the cover is open is not greater than that corresponding angle ß when the cover is in the closed position. As a result, the cover only reaches the position shown in dashed lines after the snap-in. The spring strip has already lost its spring force in this position, so that it is not able to bring the lid fully into the closed position.

Die erfindungsgemäße Ausführungsform gemäß Fig. 4 unterscheidet sich von der bekannten Ausführungsform gemäß den Fig. 1 bis 3 dadurch, daß der Anlenkpunkt FK auf einem Vorsprung 12 auf der Kappe angeordnet ist, so daß die Gerade G mit der Längsachse der Kappe einen über dem Verschluß liegenden spitzen Winkel bildet. Dies hat zur Folge, daß der entsprechende Winkele wesentlich größer ist als der Winkel ß. D.h. aber, daß in Verschlußstellung des Deckels der Federstreifen 7a seine Federkraft noch nicht eingebüßt hat. Wenn der Deckel also beim Schließen sich auf seine Verschlußstellung zubewegt, so ist noch genügend Federspannung vorhanden, um den konischen Zapfen 11a in die Ausgießöffnung zu drücken und dabei auch einen Schnappwiderstand zu überwinden. Fig. 4 zeigt die theoretische Ruhelage bei entspanntem Federstreifen ebenfalls gestrichelt eingezeichnet.The embodiment according to FIG. 4 differs from the known embodiment according to FIGS. 1 to 3 in that the articulation point FK is arranged on a projection 12 on the cap, so that the straight line G with the longitudinal axis of the cap over the closure lying acute angle forms. As a result, the corresponding angle is significantly larger than the angle β. I.e. but that in the closed position of the cover the spring strip 7a has not yet lost its spring force. If the lid moves towards its closed position when closed, there is still sufficient spring tension to press the conical pin 11a into the pouring opening and also to overcome a snap resistance. Fig. 4 shows the theoretical rest position with relaxed spring strip also shown in dashed lines.

Der erfindungsgemäße Verschluß unterscheidet sich von dem bekannten Verschluß lediglich durch den Fortsatz 12, eine Verdickung im mittleren Bereich des Federstreifens 7a und einen konisch ausgeführten Zapfen lla.The closure according to the invention differs from the known closure only by the extension 12, a thickening in the central region of the spring strip 7a and a conical pin 11a.
