Abstract

A two-part container closure, consisting of a cap part (10), which can be fixed on the container and has a passage opening, and a rocker lever which is fastened on the cap part so as to be pivotable between a first and a second position by means of a bearing arrangement and has a passage aligned with the passage opening of the cap part in the first position of the rocker lever, whereas the passage opening in the second position of the rocker lever is sealed off by the latter, the bearing arrangement comprising a pair of bearing journals which protrude on both sides of the rocker lever and engage in bearing depressions (23), aligned with said bearing journals, with tapered insertion openings (24) on the opposite side walls of a recess (11) in which the rocker lever is essentially held in the second position. The bearing arrangement furthermore comprises complementary catch projections and catch hollows (29), which are aligned with one another and can be brought into locking engagement with one another, on the bearing journals and bearing depressions (23) respectively, thus forming the axis of rotation about which the rocker lever can be pivoted. Each bearing depression (23) is formed at least along a part of its circumference by a web-shaped moulding (27), extending from the insertion opening (24), on the side wall (13) of the recess (11). <IMAGE>

Description

Die Erfindung betrifft einen Behälterverschluss gemäss Oberbegriff des Schutzanspruches 1.The invention relates to a container closure according to the preamble of claim 1.

Derartige sog. Kipphebelverschlüsse sind bekannt. Es kann z.B. auf die DE-PSen 12 04 959 sowie 16 07 904 verwiesen werden. Bei den bekannten Verschlüssen sind die Lagerzapfen des Kipphebels in Lagermulden des Kappenteiles unter Schnappsitz aufgenommen, indem die Lagerzapfen in die Lagermulden durch Einführöffnungen hindurchgeführt werden müssen, die eine geringere Weite als der Durchmesser der Zapfen haben. Für das Einführen der Lagerzapfen ist daher ein bestimmter Kraftaufwand erforderlich. Der Kraftaufwand kann erheblich sein, da die Lagermulden durch im wesentlichen starre Wandbereiche einer Ausnehmung im Kappenteil gebildet sind, was Montageschwierigkeiten bereiten kann. Es wurde ausserdem festgestellt, dass die bekannten Verschlüsse häufig nicht die gewünschte Abdichtung schaffen, was auf ein oftmals übermässiges Spiel der Lagerzapfen in den Lagermulden zurückgeführt werden kann, zumal sich ein Druck im Inneren des abzudichtenden Behälters in einer Bewegung des Kipphebels aus der abdichtenden Beziehung mit einer Durchgangsöffnung im Kappenteil äussern kann, die die Verbindung zum Behälterinneren schafft. Ein weiterer Nachteil der bekannten Verschlüsse ist, dass deren Lageranordnung, bestehend aus den Lagerzapfen und Lagermulden, in der Schliesstellung des Kipphebels von aussen sichtbar ist, so dass die Verschlüsse nicht nur ein ästhetisch wenig ansprechendes Aussehen haben, sondern dieses Aussehen zusätzlich durch Verschmutzungen der Lageranordnung infolge Leckagen beeinträchtigt werden kann.Such so-called rocker arm locks are known. For example, reference may be made to DE-PS 12 04 959 and 16 07 904. In the known closures, the journals of the rocker arm are snapped into the recesses of the cap part in that the journals have to be guided into the bearing recesses through insertion openings which have a smaller width than the diameter of the journals. A certain amount of force is therefore required to insert the trunnion. The effort can be considerable since the bearing troughs are formed by essentially rigid wall areas of a recess in the cap part, which can cause installation difficulties. It was also found that the known closures often do not provide the desired seal, which can be attributed to an often excessive play of the journals in the bearing recesses, especially since a pressure inside the container to be sealed in a movement of the rocker arm results from the sealing relationship a through opening in the cap part that creates the connection to the interior of the container. Another disadvantage of the known closures is that their bearing arrangement, consisting of the bearing journals and bearing recesses, is visible from the outside in the closed position of the rocker arm, so that the closures not only have an aesthetically unappealing appearance, but this appearance can also be affected by contamination of the bearing assembly due to leakage.

Der Erfindung liegt daher die Aufgabe zugrunde, einen Behälterverschluss der eingangs erwähnten Gattung zu schaffen, der hinsichtlich der Dichtfunktion verbessert ist und ästhetisch ansprechend ausgebildet werden kann.The invention is therefore based on the object of providing a container closure of the type mentioned at the outset which is improved with regard to the sealing function and can be designed to be aesthetically pleasing.

Die Aufgabe wird erfindungsgemäss durch die Merkmale des Schutzanspruches 1 gelöst. Danach erfolgt die drehbewegliche Fixierung des Kipphebels am Kappenteil nicht nur durch den Eingriff der Lagerzapfen in Lagermulden. Es sind vielmehr darüber hinaus Rastmittel vorgesehen, die miteinander in Eingriff treten und die Drehachse exakt definieren, um die der Kipphebel geschwenkt werden kann. Die Lage der Drehachse ist daher nicht von einem Spiel zwischen Lagerzapfen und Lagermulden abhängig. Ausserdem kann die Drehachse ohne weiteres so angeordnet werden, dass die Dichtfläche des Kipphebels unter Vorspannung gegen die Dichtfläche längs der Durchgangsöffnung des Kappenteiles gedrückt wird. Dies gewährleistet, dass auch unter einem Innendruck des Behälters die dichtende Eingriffnahme nicht verlorengeht. Die erfindungsgemässe Halterung des Kipphebels mittels der Rastmittel schafft ferner die Voraussetzung für eine vorteilhafe Ausbildung wenigstens eines Teiles des Umfanges der Lagermulden durch eine stegartige Anformung an den Seitenwänden der Ausnehmung im Kappenteil. Dieser Bereich der Lagermulde besitzt daher eine gewisse Flexibilität, was das Einführen des Lagerzapfens in die Lagermulde durch die Einführöffnung erleichtert. Die Montage von Kipphebel und Kappenteil ist daher entsprechend vereinfacht. Ferner werden geringere Anforderungen an die Passungsgenauigkeit zwischen Lagermulde und Lagerzapfen gestellt, da die Fixierung des Kipphebels im wesentlichen durch die Rastmittel schon ausreichend gesichert ist. Die stegartige Anformung schafft ferner gemäss einer Weiterbildung der Erfindung einen Freiraum in der Ausnehmung des Kappenteiles, der einen Endabschnitt einer Abdeckplatte am Kappenteil aufnehmen kann, wenn der Kipphebel in die Freigabestellung geschwenkt wird. Die Abdeckplatte kann daher ausreichend gross bemessen werden, dass sie in der Schliesstellung des Kipphebels die Ausnehmung einschliesslich der Lageranordnung weitestgehend nach aussen hin abdeckt, so dass das erwähnte beeinträchtigte Aussehen der bekannten Verschlüsse vermieden wird. Bezüglich anderer Weiterbildungen der Erfindung wird auf die Schutzansprüche verwiesen.The object is achieved according to the invention by the features of claim 1. Thereafter, the rocking lever is fixed in rotation on the cap part not only by the engagement of the bearing pins in the bearing recesses. Rather, locking means are also provided, which engage with one another and exactly define the axis of rotation about which the rocker arm can be pivoted. The position of the axis of rotation is therefore not dependent on play between the bearing journal and the bearing recesses. In addition, the axis of rotation can easily be arranged such that the sealing surface of the rocker arm is pressed against the sealing surface along the passage opening of the cap part under prestress. This ensures that the sealing engagement is not lost even when the container is under internal pressure. The inventive mounting of the rocker arm by means of the latching means also creates the prerequisite for an advantageous formation of at least a part of the circumference of the bearing troughs by means of a web-like molding on the side walls of the recess in the cap part. This area of the bearing recess therefore has a certain flexibility, which facilitates the insertion of the bearing pin into the bearing recess through the insertion opening. The assembly of rocker arm and cap part is therefore simplified accordingly. Furthermore, lower requirements are placed on the accuracy of fit between the bearing recess and the bearing journal, since the fixing of the rocker arm essentially already takes place by the latching means is adequately secured. According to a further development of the invention, the web-like formation also creates a free space in the recess of the cap part, which can accommodate an end section of a cover plate on the cap part when the rocker arm is pivoted into the release position. The cover plate can therefore be dimensioned sufficiently large that it largely covers the recess, including the bearing arrangement, to the outside in the closed position of the rocker arm, so that the aforementioned impaired appearance of the known closures is avoided. With regard to other developments of the invention, reference is made to the claims for protection.

Die Erfindung wird nachfolgend anhand einer Ausführungsform und der Zeichnung näher erläutert. Es zeigen:

  • Fig. 1 in teilweise geschnittener Ansicht einen Behälterverschluss nach der Erfindung,
  • Fig. 2 in längsgeschnittener Ansicht den Kappenteil des Verschlusses,
  • Fig. 3 und 4 in vergrösserter Seiten- bzw. Vorderansicht den Kipphebel des Verschlusses.
The invention is explained in more detail below using an embodiment and the drawing. Show it:
  • 1 is a partially sectioned view of a container closure according to the invention,
  • 2 in longitudinal section the cap part of the closure,
  • 3 and 4 in an enlarged side and front view, the rocker arm of the closure.

Wie in Fig. 1 gezeigt ist, umfasst der Verschluss für einen nicht gezeigten Behälter oder eine Flasche einen das allgemeine Bezugszeichen 10 tragenden Kappenteil und einen das allgemeine Bezugszeichen 100 tragenden Kipphebel, der relativ zum Kappenteil zwischen einer durch ausgezogene Linien in Fig. 1 gezeigten ersten oder Schliesstellung und einer durch strichpunktierte Linien in Fig. 1 gezeigten zweiten oder Freigabestellung schwenkbar ist.As shown in FIG. 1, the closure for a container or a bottle, not shown, comprises a cap part bearing the general reference number 10 and a rocker arm bearing the general reference number 100, which is relative to the cap part between a first one shown by solid lines in FIG. 1 or closed position and a second or release position shown by dash-dotted lines in Fig. 1 is pivotable.

Wie Fig. 2 zeigt, kann der Kappenteil 10 eine grundsätzlich napfförmige Konfiguration haben, doch sind auch andere geeignete Formgebungen möglich. In der Oberseite des Kappenteiles 10 ist eine dem Raumbedarf des Kipphebels 100 angepasste Ausnehmung oder Kavität 11 vorgesehen ist, in der der Kipphebel 100 in der Schliesstellung im wesentlichen aufgenommen ist. Die Ausnehmung 11 ist durch eine Bodenwand 12, gegenüberliegende Seitenwände 13 sowie äussere und innere Endwände 14 bzw. 15 definiert und im übrigen nach oben hin offen. Die Seitenwände 13 können ab einer zwischenliegenden Stelle in Richtung aufeinanderzu versetzt sein, so dass die Ausnehmung 11 in der Draufsicht eine T-förmige Konfiguration haben kann.As FIG. 2 shows, the cap part 10 can have a basically cup-shaped configuration, but other suitable shapes are also possible. Provided in the top of the cap part 10 is a recess or cavity 11 which is adapted to the space required by the rocker arm 100 and in which the rocker arm 100 is essentially accommodated in the closed position. The recess 11 is defined by a bottom wall 12, opposite side walls 13 and outer and inner end walls 14 and 15, respectively, and is otherwise open at the top. The side walls 13 can be offset towards one another from an intermediate point, so that the recess 11 can have a T-shaped configuration in plan view.

In der Bodenwand 12 der Ausnehmung 11 ist eine Durchgangsöffnung 16 vorgesehen, die von einer Dichtfläche 17 mit einer Krümmung umgeben sein kann, die der Krümmung einer komplementären Dichtfläche 101 am Kipphebel 100 angepasst ist. Wenn erwünscht, kann ferner längs der Durchgangsöffnung 16 eine ringförmige Dichtlippe vorgesehen sein.A through opening 16 is provided in the bottom wall 12 of the recess 11, which can be surrounded by a sealing surface 17 with a curvature that is adapted to the curvature of a complementary sealing surface 101 on the rocker arm 100. If desired, an annular sealing lip can also be provided along the passage opening 16.

Wie Fig. 2 weiter zeigt, ist an einer zwischenliegenden Stelle einer Kappenumfangswand 19 in radialem Abstand dazu ein Kragen 20 angeformt, an dessen Innenseite ein Gewinde 21 vorgesehen ist, dem ein Gewinde am Hals eines Behälters (nicht gezeigt) entspricht, um den Kappenteil 10 am Behälter zu befestigen. Eine untere Verlängerung 22 der Kappenumfangswand 19 kann vorgesehen sein, um einen Dichtkonus zu bilden, der bei aufgeschraubtem Kappenteil 10 dichtend in die Mündungsöffnung des Behälterhalses eingreift.As further shown in FIG. 2, a collar 20 is formed at an intermediate location of a cap peripheral wall 19 at a radial distance therefrom, on the inside of which a thread 21 is provided, which corresponds to a thread on the neck of a container (not shown) around the cap part 10 to attach to the container. A lower extension 22 of the cap circumferential wall 19 can be provided in order to form a sealing cone which, when the cap part 10 is screwed on, engages sealingly in the mouth opening of the container neck.

Es versteht sich jedoch, dass die Erfindung nicht auf die beschriebene Art der Befestigung des Kappenteiles 10 am Behälter beschränkt ist, sondern z.B. das Gewinde auch an der Innenseite der Kappenumfangswand 19 vorgesehen sein könnte. Auch könnte statt einer Schraubverbindung die Befestigung des Kappenteiles 10 am Behälter in kraftschlüssiger Weise durch Aufprellen erfolgen.However, it goes without saying that the invention is not restricted to the described manner of fastening the cap part 10 to the container, but rather, for example, also the thread on the Inside of the cap peripheral wall 19 could be provided. Also, instead of a screw connection, the cap part 10 could be attached to the container in a force-locking manner by bouncing.

An einem der inneren Endwand 15 benachbarten Bereich der Seitenwände 13 der Ausnehmung 11 sind gegenüberliegende zueinander ausgerichtete Lagermulden oder -taschen 23 vorgesehen, die so ausgebildet sind, dass darin entsprechend ausgerichtete Lagerzapfen 102, vgl. Fig. 4, die beidseitig vom Kipphebel 100 abstehen, drehbeweglich aufgenommen werden können. Jede Lagermulde 23 hat eine nach oben weisende Einführöffnung 24 mit einer Weite, die geeignet kleiner als der Durchmesser des Lagerzapfens 102 ist, so dass dieser mit einer gewissen äusseren Kraft durch die Einführöffnung 24 in die Lagermulde 23 eingedrückt werden kann und darin anschliessend gehalten ist.On a region of the side walls 13 of the recess 11 which is adjacent to the inner end wall 15, bearing troughs or pockets 23 which are opposite one another and are provided and are designed such that correspondingly aligned bearing journals 102, cf. Fig. 4, which protrude from the rocker arm 100 on both sides, can be rotatably received. Each bearing recess 23 has an upward-pointing insertion opening 24 with a width that is suitably smaller than the diameter of the bearing journal 102, so that it can be pressed into the bearing recess 23 through the insertion opening 24 with a certain external force and is subsequently held therein.

Jede Lagermulde 23 wird längs eines ersten Teiles ihres Umfanges durch einen Wandungsbereich der Seitenwand 13 der Ausnehmung 11, der damit im wesentlichen starr ist, und längs eines zweiten Teiles ihres Umfanges, der sich an den ersten Teil kontinuierlich anschliesst und bis zur Einführöffnung 24 reicht, durch eine stegartige Anformung 27 an der Seitenwand 13 gebildet, die in einem geeigneten Abstand von der inneren Endwand 15 steht und eine gewisse Flexibilität besitzt, die das Einführen des Lagerzapfens 102 in die Lagermulde 23 erleichtert.Each bearing trough 23 is along a first part of its circumference through a wall region of the side wall 13 of the recess 11, which is thus essentially rigid, and along a second part of its circumference, which continuously adjoins the first part and extends to the insertion opening 24, formed by a web-like projection 27 on the side wall 13, which is at a suitable distance from the inner end wall 15 and has a certain flexibility, which facilitates the insertion of the bearing pin 102 into the bearing recess 23.

Die stegartige Anformung 27 schafft ausserdem einen Freiraum 28 vor der inneren Endwand 15 der Ausnehmung 11, in dem ein innerer Endabschnitt 104 einer Abdeckplatte 103 des Kipphebels 100 aufgenommen werden kann, wenn dieser von der Schliess- in die Freigabestellung geschwenkt wird, worauf nachfolgend noch näher eingegangen wird.The web-like projection 27 also creates a free space 28 in front of the inner end wall 15 of the recess 11, in which an inner end portion 104 of a cover plate 103 of the rocker arm 100 can be accommodated, if this of the Closing is pivoted into the release position, which will be discussed in more detail below.

Erfindungsgemäss ist ferner an einer zentralen Stelle jeder Lagermulde 23 eine z.B. halbkugelförmige Rastvertiefung 29 in der Seitenwand 23 der Ausnehmung 11 vorgesehen. Die gegenüberliegenden Rastvertiefungen 29 sind zueinander ausgerichtet und können komplementär geformte ausgerichtete Rastvorsprünge 105 an den Stirnseiten der Lagerzapfen 102 des Kipphebels 100 aufnehmen, wenn die Lagerzapfen 102 in den Lagermulden 23 des Kappenteiles 10 aufgenommen sind. Die Rastvertiefungen 29 und Rastvorsprünge 105 definieren die Drehachse, um die der Kipphebel 100 schwenkbar ist. Die Drehachse kann in einem geeigneten Abstand von der Dichtfläche 17 der Ausnehmung 11 liegen, so dass die Dichtfläche 101 des Kipphebels 100 mit einer geigneten Vorspannkraft gegen die Dichtfläche 17 des Kappenteiles 10 gedrückt wird, ohne dass dadurch die Drehbeweglichkeit des Kipphebels 100 wesentlich eingeschränkt wird.According to the invention, a e.g. hemispherical locking recess 29 is provided in the side wall 23 of the recess 11. The opposite locking recesses 29 are aligned with one another and can receive complementarily shaped, aligned locking projections 105 on the end faces of the bearing pins 102 of the rocker arm 100 when the bearing pins 102 are received in the bearing recesses 23 of the cap part 10. The locking recesses 29 and locking projections 105 define the axis of rotation about which the rocker arm 100 is pivotable. The axis of rotation can be at a suitable distance from the sealing surface 17 of the recess 11, so that the sealing surface 101 of the rocker arm 100 is pressed with a suitable pretensioning force against the sealing surface 17 of the cap part 10, without the rotational mobility of the rocker arm 100 being significantly restricted thereby.

In Fig. 3 und 4 ist der Kipphebel 100 in vergrössertem Masstab gezeigt. Der Kipphebel 100 umfasst einen rohrförmigen, von einer Durchgangsbohrung 106 axial durchsetzten Basisteil 107, der innerends an einem zylindrischen Abschnitt 108 endet, der die Dichtfläche 101 bildet und ebenfalls von der Durchgangsbohrung 106 durchsetzt ist. An den Stirnseiten der seitlich vom zylindrischen Abschnitt 108 nach aussen ragenden Lagerzapfen 102 sind die Rastvorsprünge 105 vorgesehen, die in die Rastvertiefungen 29 des Kappenteiles 10 eingreifen können.3 and 4, the rocker arm 100 is shown on an enlarged scale. The rocker arm 100 comprises a tubular base part 107 which is axially penetrated by a through bore 106 and which ends on the inside at a cylindrical section 108 which forms the sealing surface 101 and is likewise penetrated by the through bore 106. On the end faces of the bearing pins 102 projecting laterally from the cylindrical section 108, the locking projections 105 are provided, which can engage in the locking recesses 29 of the cap part 10.

Der Kipphebel 100 trägt ferner an seiner Oberseite die Abdeckplatte 103, die sich von dem zylindrischen Abschnitt 108 bis über das freie Ende des rohrförmigen Basisteiles 107 hinaus erstreckt und eine Abmessung haben kann, dass in der Schliesstellung des Kipphebels 100 die Ausnehmung 11 des Kappenteiles 10 nach auusen hin im wesentlichen abgedeckt ist, wobei die Abdeckplatte 103 mit der Oberseite des Kappenteiles 10 fluchten kann. Insbesondere kann in der Schliesstellung des Kipphebels 100 die Lageranordnung bestehend aus den Lagerzapfen 102 und Lagermulden 23 durch die Abdeckplatte 103 nach aussen abgedeckt sein, so dass der Verschluss ein ästhetisch ansprechendes Aussehen hat und eventuell im Bereich der Lageranordnung vorhandene Verschmutzungen aus Leckagen nicht nach aussen in Erscheinung treten.The rocker arm 100 also carries on its upper side the cover plate 103, which extends from the cylindrical section 108 to the free end of the tubular base part 107 extends and can have a dimension that in the closed position of the rocker arm 100, the recess 11 of the cap part 10 is substantially covered outwards, the cover plate 103 being able to align with the top of the cap part 10. In particular, in the closed position of the rocker arm 100, the bearing arrangement consisting of the bearing pins 102 and bearing troughs 23 can be covered to the outside by the cover plate 103, so that the closure has an aesthetically pleasing appearance and any contamination from leaks in the area of the bearing arrangement cannot be covered to the outside in Appearance.

Infolge des Freiraumes 28 zwischen der inneren Endwand 15 der Ausnehmung 11 des Kappenteiles 10 und der benachbarten stegartigen Anformung 27 wird die Schwenkbewegung des Kipphebels 100 in die Freigabestellung durch die Abdeckplatte 103 nicht behindert, da der Endabschnitt 104 der Abdeckplatte 103 von dem Freiraum 28 aufgenommen werden kann, wenn der Kipphebel 100 in die Freigabestellung geschwenkt wird, vgl. Fig. 1.As a result of the free space 28 between the inner end wall 15 of the recess 11 of the cap part 10 and the adjacent web-like projection 27, the pivoting movement of the rocker arm 100 into the release position is not impeded by the cover plate 103, since the end section 104 of the cover plate 103 is received by the free space 28 can, if the rocker arm 100 is pivoted into the release position, cf. Fig. 1.

Darauf hinzuweisen ist ferner, dass eine über das freie äussere Ende des rohrförmigen Basisteiles 107 hinausragende Abschnitt 109 der Abdeckplatte 103 die Handhabung des Kipphebels erleichtert, indem daran z.B. der Daumen einer Hand angesetzt werden kann.It should also be pointed out that a section 109 of the cover plate 103 protruding beyond the free outer end of the tubular base part 107 facilitates the handling of the rocker arm, e.g. the thumb of one hand can be attached.

Die Erfindung wurde vorausgehend anhand einer bevorzugten Ausführungsform beschrieben. Sie ist jedoch hierauf nicht beschränkt. So versteht es sich, dass anstelle der halbkugelförmigen Rastvorsprünge am Kipphebel und der komplementären Rastvertiefungen am Kappenteil auch umgekehrt, die Rastvorsprünge am Kappenteil und die Rastvertiefungen am Kipphebel vorgesehen sein können. Ausserdem können die Rastvertiefungen/-vorsprünge auch eine andere geeignete Konfiguration als die halbkugelförmige haben. Ferner kann, wenn erwüncht, jede Lagermulde gesamtumfänglich durch eine stegartige Anformung ähnlich der beschriebenen gebildet sein, was eine besondere Nachgiebigkeit für die Einführung der Lagerzapfen in die Lagermulden schafft.The invention has been described above with reference to a preferred embodiment. However, it is not limited to this. So it goes without saying that instead of the hemispherical locking projections on the rocker arm and the complementary locking recesses on the cap part also vice versa, the locking projections on the cap part and the locking recesses on Rocker arms can be provided. In addition, the locking recesses / projections can also have a suitable configuration other than the hemispherical one. Furthermore, if desired, each bearing trough can be formed in its entirety by a web-like formation similar to that described, which creates a particular flexibility for the introduction of the bearing pins into the bearing troughs.
