Description

Selbstschliessender Behälterverschluss Self-closing container closure
Die Erfindung betrifft einen selbstschliessenden Verschluss zum Einbau in eine Spendeöffnung in einem Behälter, Kappenteil oder dgl ..The invention relates to a self-closing closure for installation in a dispensing opening in a container, cap part or the like.
Ein bekannter gattungsgemässer Verschluss (DE-A-42 14 153) umfasst ein steifes Oberteil, das über eine membranartige nachgiebige Verbindungswand mit einem steifen Innenteil verbunden ist, das einerseits auf einen Behälterhals aufgeschraubt werden kann und von dem andererseits ein stationärer Dichtzapfen absteht. Der Dichtzapfen kann in eine Durchtrittsöffnung im Oberteil dichtend eingreifen, wenn auf diesen keine äussere Kraft einwirkt. Dagegen bewirkt eine Hebekraft auf den Oberteil, dass der Dichtzapfen aus dem dichtenden Eingriff mit der Durchtrittsöffnung herausgebracht wird. Der bekannte Verschluss hat einen vergleichsweise komplizierten, fertigungsungünstigen Aufbau. Insbesondere nachteilig ist, dass er nicht geeignet ist, um an eine vorgegebene Konfiguration, z.B. der Rundung eines Behälters ohne wesentliche Beeinträchtigung dessen Aussehens angepasst werden zu können. Ein selbstschliessender Verschluss mit einem ähnlichen Aufbau ist auch aus der DE-A-23 40 319 bekannt . Das Aussehen dieses Verschlusses ist durch eine aussen freiliegende Verbindungswand wesentlich zusätzlich beeinträchtigt . Der Erfindung liegt die Aufgabe zugrunde, einen selbstschliessenden Verschluss der eingangs erwähnten Art zu schaffen, der bei vereinfachtem, fertigungsgünstigen und bedienungsfreundlichen Aufbau die Möglichkeit für eine weitestgehende Integration und Anpassung an die Konfiguration des Teiles bietet, dessen Spendeöffnung verschlossen werden soll .A known generic closure (DE-A-42 14 153) comprises a rigid upper part which is connected via a membrane-like flexible connecting wall to a rigid inner part, which on the one hand can be screwed onto a container neck and on the other hand from which a stationary sealing pin protrudes. The sealing pin can engage in a passage opening in the upper part if there is no external force acting on it. In contrast, a lifting force on the upper part causes the sealing pin to be brought out of the sealing engagement with the passage opening. The known closure has a comparatively complicated, manufacturing-unfavorable structure. A particular disadvantage is that it is not suitable for being able to be adapted to a given configuration, for example the rounding of a container, without significantly impairing its appearance. A self-closing closure with a similar structure is also known from DE-A-23 40 319. The appearance of this closure is significantly impaired by an exposed connection wall. The invention has for its object to provide a self-closing closure of the type mentioned, which with a simplified, inexpensive and user-friendly structure offers the possibility for the greatest possible integration and adaptation to the configuration of the part whose donation opening is to be closed.
Diese Aufgabe wird erfindungsgemäss durch einene selbstschliessenden Verschluss zum Einbau in einer Spendeöffnung in einem Behälter, Kappenteil oder dgl., mit einem eine Durchtrittsöffnung enthaltenden Oberwandteil und einem von unterseitig des Oberwandteils aus in die Durchtrittsöffnung eingreifenden, von einem Verschlussinnenteil abstehenden Dichtzapfen, der unter der Wirkung einer auf den Oberwandteil ausgeübten Kraft gegen eine Vorspannkraft aus der dichtenden Eingriffnahme mit der Durchtrittsöffnung bringbar ist, wobei erfindungsgemäss der Oberwandteil wenigstens oberseitig eine an die Oberflächenkontur des Behälters bündig anpassbare Konfiguration hat und wenigstens an einem Betätigungsbereich elastisch nachgiebig ausgebildet ist, so dass der Betätigungsbereich unter einer darauf von aussen ausgeübten Handkraft elastisch konkav verformbar ist, und wobei Mittel vorgesehen sind, um die konkave Verformung des Betätigungsbereichs in eine Relativbewegung zwischen dem Dichtzapfen und der Durchtrittsöffnung umzusetzen. Der Verschluss zeichnet sich durch einen Oberwandteil aus, der ganz oder teilweise nachgiebig ausgebildet sein kann, so dass eine darauf ausgeübte Kraft eines Fingers oder Daumens einer Bedienungsperson eine konkave Einbeulung bewirken kann. Ohne eine derartige Karft schafft der Oberwandteil dagegen eine im wesentlichen glatte äussere Ooberflache, die eine Fortsetzung der benachbarten Oberfläche eines Behälters oder anderen Bauteils darstellen kann, an dem der Verschluss montiert ist. Der Verschluss beeinträchtigt daher die äussere Konfiguration des Bauteiles praktisch nicht. Die durch die Einbeulung des Oberwandteils unter der besagten Kraft geschaffene Bewegung wird mit einfachen Mitteln ausgenutzt, um zwischen einer Durchtrittsöffnung im Oberwandteil und einem damit zusammenwirkenden Dichtzapfen eine Relativbewegung zu erzeugen, so dass der Dichtzapfen ausser Eingriff mit der Durchtrittsöffnung gebracht werden kann. Eine besonders bevorzugte, da fertigungstechnisch günstige Ausführung der Erfindung, sieht zu diesem Zweck vor, dass der Dichtzapfen schwenkbar am Verschlussinnenteil gehalten ist und die Einbeulung des Oberwandteils über ein einfaches Übertragungsglied auf den Dichtzapfen übertragen werden kann. Bei dieser Ausführungsform könnte das Verschlussinnenteil mit dem Dichtzapfen auch integraler Bestandteil des Bauteiles sein, so dass lediglich der Oberwandteil hinzugefügt werden müsste. Der Oberwandteil und der Verschlussinnenteil können jedoch auch separate Teile darstellen, die nachträglich in eine Spendeöffnung des betreffenden Bauteils eingesetzt werden. In jedem Fall wird eine ästhetisch ansprechende glatte äussere Oberfläche im Bereich der Spendeöffnung erhalten, die weitestgehend der Konfiguration des Bauteils angepasst ist und z.B. mit Werbehinweisen wie die benachbarten Wandbereiche des Bauteils bedruckt werden kann, ohne dass das Druckbild beeinträchtigt wird.This object is achieved according to the invention by means of a self-closing closure for installation in a dispensing opening in a container, cap part or the like, with an upper wall part containing a passage opening and a sealing pin which engages in the passage opening from the underside of the upper wall part and protrudes from an inner closure part and under the action a force exerted on the top wall part against a prestressing force can be brought from the sealing engagement with the passage opening, the top wall part according to the invention at least on the top side having a configuration which can be adapted flush to the surface contour of the container and being designed to be elastically flexible at least in one actuation area, so that the actuation area below a hand force exerted thereon is elastically concavely deformable, and means are provided to convert the concave deformation of the actuation area into a relative movement between the di chaps and the passage opening. The closure is characterized by an upper wall part, which can be designed to be completely or partially flexible, so that a force exerted on it by an operator's finger or thumb can cause a concave indentation. Without such a carpet, on the other hand, the top wall part creates an essentially smooth outer surface, which is a continuation of the adjacent surface of a container or other Can represent component on which the closure is mounted. The closure therefore practically does not affect the external configuration of the component. The movement created by the indentation of the upper wall part under the said force is used with simple means in order to generate a relative movement between a through opening in the upper wall part and a sealing pin interacting therewith, so that the sealing pin can be disengaged from the through opening. A particularly preferred embodiment of the invention which is favorable in terms of production technology provides for this purpose that the sealing pin is pivotally held on the inner part of the closure and the bulge of the upper wall part can be transferred to the sealing pin via a simple transmission member. In this embodiment, the inner closure part with the sealing pin could also be an integral part of the component, so that only the top wall part would have to be added. The upper wall part and the inner part of the closure can, however, also represent separate parts which are subsequently inserted into a dispensing opening of the component in question. In any case, an aesthetically pleasing smooth outer surface is obtained in the area of the dispensing opening, which is largely adapted to the configuration of the component and can be printed, for example, with advertising information such as the adjacent wall areas of the component, without the print image being impaired.

Obschon die Erfindung nachfolgend in Verbindung mit dem Verschliessen einer in einer Behälterwand vorgesehenen Spendeöffnung beschrieben wird, versteht es sich, dass die Erfindung auch zum Verschliessen anderer Öffnungen oder Ausnehmungen, z.B. in Verschlusskappen, eingesetzt werden kann und daher auf das beschriebene Anwendungsgebiet nicht begrenzt ist.Although the invention is described below in connection with the closure of a dispensing opening provided in a container wall, it is understood that the invention also for closing other openings or recesses, e.g. in caps, can be used and is therefore not limited to the described field of application.
Wie in Fig. 1 gezeigt ist, ist der selbstschliessende Verschluss nach der Erfindung in einer Spendeöffnung (nicht bezeichnet) in der Wand 3 eines Behälters 2 angeordnet. Der Verschluss umfasst ein Oberwandteil 6, das, wie dargestellt, oberseitig bündig mit der Behälterwand 3 fluchtend übereinstimmen kann und sich auf am Behälter 2 angeformten Auflagern 7, 8 abstützt.As shown in FIG. 1, the self-closing closure according to the invention is arranged in a dispensing opening (not designated) in the wall 3 of a container 2. The closure comprises an upper wall part 6 which, as shown, can align flush with the container wall 3 on the upper side and is supported on supports 7, 8 formed on the container 2.
Der Oberwandteil 6 kann irgendeine der Umrisskonfiguration der Spendeöffnung angepasste Umfangskonfiguration haben, um eine bündige Fortsetzung der gewölbten Behälterwand 3 zu schaffen.The top wall part 6 can have any circumferential configuration adapted to the outline configuration of the dispensing opening in order to create a flush continuation of the curved container wall 3.
Eine Duchtrittsöffnung 9 ist im Oberwandteil 6 an einer Stelle nahe einem radial versetzten Umfangsbereich vorgesehen, in die ein Dichtzapfen 11 dichtend eingreifen kann. Der Dichtzapfen 11 ist an einem Verschlussinnenteil 10 angeformt, und insbesondere an einem federnden Verknüpfungsglied 12 in Gestalt eines z.B. U-förmigen Ausschnittes aus dem Verschlussinnenteil 10, so dass das Verknüpfungsglied 12, welches an seinem einen Ende den Dichtzapfen 11 trägt, an seinem anderen Ende mit dem Verschlussinnenteil 10 in Verbindung steht. Das Verknüpfungsglied 12 kann daher zusammen mit dem Dichtzapfen 11 aus der Ebene des Verschlussinnenteiles 10 herausgeschwenkt werden, wobei es in die in Fig. 1 gezeigte Ausgangsstellung in der Ebene des Verschlussinnenteils 10 aufgrund der natürlichen Elastizität des Materials zurückfedert, wenn auf das Verknüpfungsglied 12 keine äussere Kraft einwirkt . Die äussere Kraft kann vom Daumen oder Finger einer Bedienungsperson ausgeübt werden, wie dies in Fig. 1A gezeigt ist.A passage opening 9 is provided in the upper wall part 6 at a location near a radially offset circumferential area, into which a sealing pin 11 can engage in a sealing manner. The sealing pin 11 is on a closure inner part 10 integrally formed, and in particular on a resilient connecting member 12 in the form of, for example, a U-shaped cutout from the inner closure part 10, so that the connecting member 12, which carries the sealing pin 11 at one end, is connected to the inner closure part 10 at its other end. The link 12 can therefore be pivoted together with the sealing pin 11 out of the plane of the inner closure part 10, whereby it springs back into the starting position shown in FIG. 1 in the plane of the inner closure part 10 due to the natural elasticity of the material if there is no outer surface on the link 12 Acts force. The external force can be exerted by an operator's thumb or finger, as shown in Fig. 1A.
Der Oberwandteil 6 ist wenigstens bereichsweise strukturell elastisch ausgebildet und/oder besteht aus einem elastischen Material, z.B. einem elastomeren Material, welches unter der Einwirkung einer äusseren Kraft unter Bildung einer Einbeulung nachgibt, wie dies in Fig. 1A bei 6', im folgenden auch Betätigungsbereich genannt, gezeigt ist. Am Verknüpfungsglied 12 ist ferner ein Wegübertragungsglied 13 in Gestalt einer Zunge angeformt, die mit ihrem freien Ende an der Unterseite des Oberwandteils 6 anliegt oder damit in anderer geeigneter Weise in Eingriff steht, damit eine Bewegung des Oberwandteiles 6 an dessen Betätigungsbereich 6' zu einer gleichgerichteten Bewegung des Verknüpfungsglieds 12 führen kann. Aufgrund der elastischen Eigenschaft des Oberwandteils 6 einerseits und des Verknüpfungsglieds 12 andererseits werden beide Teile in die in Fig. 1 gezeigte Ausgangsstellung zurückfedern, sobald die auf den Oberwandteil 1 ausgeübte Kraft weggenommen wird. Bei der dann wieder eingenommenen Ausgangsstellung der Teile greift der Dichtzapfen 11 in die Durchtrittsöffnung 9 im Oberwandteil 6 ein, um diese zu verschliessen. Bei einwirkender Kraft kommt dagegen der Dichtzapfen 11 ausser Eingriff mit der Durchtrittsöffnung 9, so dass ein im Behälter befindliches Medium längs des Dichtzapfens 11 und durch die Durchtrittsöffnung 9 nach aussen strömen kann, wie dies durch den Pfeil in Fig. 1A angedeutet ist.The top wall part 6 is structurally elastic at least in some areas and / or consists of an elastic material, for example an elastomeric material, which yields under the action of an external force with the formation of a dent, as shown in FIG. 1A at 6 ', in the following also the actuating area called, is shown. On the link 12, a path transmission member 13 is also formed in the form of a tongue, which abuts with its free end on the underside of the upper wall part 6 or is in other suitable engagement, so that a movement of the upper wall part 6 at its actuating region 6 'to a rectified Movement of the link 12 can lead. Due to the elastic properties of the upper wall part 6 on the one hand and the connecting member 12 on the other hand, both parts will spring back into the starting position shown in FIG. 1 as soon as the force exerted on the upper wall part 1 is removed. When the parts are returned to the starting position, the grips Sealing pin 11 into the passage opening 9 in the upper wall part 6 in order to close it. When the force acts, on the other hand, the sealing pin 11 disengages from the passage opening 9, so that a medium in the container can flow outwards along the sealing pin 11 and through the passage opening 9, as indicated by the arrow in FIG. 1A.
Der Oberwandteil 6 kann, wenn erwünscht, insgesamt oder nur an seinem Betätigungsbereich 6' elastisch ausgebildet sein. Ferner kann zur Montage des Verschlussinnenteils 10 an der Behälterwand 3 eine durchgehende oder unterteilte Rasthülse 4 mit einem Rastbund 5 am freien Ende angeformt sein, der den Verschlussinnenteil 10 untergreifen kann.If desired, the top wall part 6 can be elastic in its entirety or only at its actuation area 6 '. Furthermore, for the assembly of the inner closure part 10 on the container wall 3, a continuous or subdivided locking sleeve 4 can be formed with a locking collar 5 at the free end, which can engage under the inner closure part 10.
In Fig. 2 und 2A ist eine zweite Ausführungsform der Erfindung gezeigt, bei der gleiche oder ähnliche Teile wie bei der ersten Ausführungsform die gleichen Bezugszeichen tragen und nicht erneut beschrieben werden müssen. Die zweite Ausführungsform hat einen Verschlussinnenteil 100, der den Dichtzapfen 11 trägt und im wesentlichen starr ausgebildet ist, so dass der Dichtzapfen 11 stationär gehalten ist. Dagegen ist vorgesehen, dass der Oberwandteil 6 unter einer darauf ausgeübten Kraft eine Verformung nicht nur am Betätigungsbereich 6' sondern auch im Bereich der Durchtrittsöffnung 9 erfährt, um diese ausser Eingriff mit dem Dichtzapfen 11 anzuheben. Insbesondere ist am Verschlussinnenteil 100 ein Bock oder Auflagerteil 120 angeformt, auf dem ein in Berührung mit dem Oberwandteil 6 an dessen Betätigungsbereich 6' stehender Wippenteil 121 aufliegt, der um das Auflager 120 nach unten geschwenkt werden kann, wenn auf den Oberwandteil 6 infolge der vom Finger oder Daumen einer Bedienungsperson ausgeübten Kraft eine Einbeulung hervorgerufen wird. Diese Bewegung des Wippenteils 121 äussert sich in einer Bewegung in entgegengesetzter Richtung am anderen Ende des Wippenteils 121, die auf den Oberwandteil 6 im Bereich der Durchtrittsöffnung 9 übertragen wird und eine konvexe Verformung des Oberwandteils 6 an der Durchtrittsöffnung 9 hervorruft, so dass diese weg vom Dichtzapfen 11 bewegt wird, wie es in Fig. 2A gezeigt ist. In dieser Stellung kann, wie durch die Pfeile in Fig. 2A angedeutet ist, ein Medium im Behälter 2 über ein oder mehrere im Verschlussinnenteil 100 vorgesehene Öffnungen 122 in den Bereich zwischen Verschlussinnenteil und Oberwandteil und von dort durch die Durchtrittsöffnung 9 nach aussen strömen. Wie dargestellt, ist der Wippenteil 121 an einem die Durchtrittsöffnung 9 untergreifenden Ringelement 123 angelenkt, um die Hebebewegung des Oberwandteils 6 nahe der Durchtrittsöffnung 9 zu steuern.2 and 2A show a second embodiment of the invention, in which the same or similar parts as in the first embodiment have the same reference numerals and need not be described again. The second embodiment has an inner closure part 100 which carries the sealing pin 11 and is essentially rigid, so that the sealing pin 11 is held stationary. In contrast, it is provided that the top wall part 6 undergoes deformation not only at the actuation area 6 ′ but also in the area of the passage opening 9 under a force exerted thereon, in order to lift it out of engagement with the sealing pin 11. In particular, a trestle or support part 120 is formed on the inner closure part 100, on which a rocker part 121 which is in contact with the upper wall part 6 at its actuating region 6 'rests and which can be pivoted downward around the support 120 if the upper wall part 6 is moved as a result of the The force exerted on the fingers or thumb of an operator causes a dent. This movement of the The rocker part 121 is expressed in a movement in the opposite direction at the other end of the rocker part 121, which is transmitted to the upper wall part 6 in the area of the passage opening 9 and causes a convex deformation of the upper wall part 6 at the passage opening 9, so that the latter moves away from the sealing pin 11 as shown in Fig. 2A. In this position, as indicated by the arrows in FIG. 2A, a medium in the container 2 can flow through one or more openings 122 provided in the inner closure part 100 into the area between the inner closure part and the upper wall part and from there through the passage opening 9 to the outside. As shown, the rocker part 121 is articulated on an annular element 123 which grips under the passage opening 9 in order to control the lifting movement of the upper wall part 6 near the passage opening 9.
Fig. 3 und 3A zeigen eine dritte Ausführungsform der Erfindung, bei der gleiche oder ähnliche Teile, wie bei der zweiten in Fig. 2 und 2A gezeigten Ausführungsform, die gleichen Bezugszeichen tragen und deshalb nicht nochmals beschrieben werden brauchen. Die Ausführungsform nach Fig. 3, 3A unterscheidet sich von derjenigen nach Fig. 2, 2A im wesentlichen dadurch, dass der Wippenteil 121 einerends an einem Hülsenteil 212 angelenkt ist, welches nach Art einer Kolbenzylinderanordnung in einem Zylinderteil 213 axial geführt ist, das am Verschlussinnenteil 100 konzentrisch zum umfänglich perforierten Dichtzapfen 11 angeformt ist. Der Hülsenteil 212 untergreift den Oberwandteil 6 umfänglich der Durchtrittsöffnung 9 ähnlich wie das Ringelement 123 der zweiten Ausführungsform. Eine auf den Wippenteil 121 an einem Ende des Auflagers 120 ausgeübte Kraft bewirkt daher eine Bewegung des Hülsenteils 212 in entgegengesetzter Richtung und damit eine konvexe Ausstülpung des Oberwandteils 6 umfänglich der Durchtrittsöffnung 9. Die Bewegung des Hülsenteils 212 wird durch die Eingriffnahme mit dem Zylinderteil 213 gesteuert.3 and 3A show a third embodiment of the invention, in which the same or similar parts as in the second embodiment shown in FIGS. 2 and 2A bear the same reference numerals and therefore do not need to be described again. The embodiment according to FIGS. 3, 3A differs from that according to FIGS. 2, 2A essentially in that the rocker part 121 is articulated at one end to a sleeve part 212, which is axially guided in the manner of a piston-cylinder arrangement in a cylinder part 213, which is on the inner closure part 100 is formed concentrically to the circumferentially perforated sealing pin 11. The sleeve part 212 engages under the top wall part 6 circumferentially of the passage opening 9 similarly to the ring element 123 of the second embodiment. A force exerted on the rocker part 121 at one end of the support 120 therefore causes the sleeve part 212 to move in the opposite direction and thus a convex protuberance of the upper wall part 6 circumferentially of the passage opening 9. The movement of the sleeve part 212 is controlled by the engagement with the cylinder part 213.
In der in Fig. 3A gezeigten Position des Oberwandteils 6 nahe der Durchtrittsδffnung 9 kann ein Medium aus dem Inneren des Behälters 2 längs der Pfeile durch Durchbrechungen 214 im Dichtzapfen 11 ins Innere des Zylinderteils 213 und von dort durch den Hülsenteil 212 über die Durchtrittsδffnung 9 nach aussen gelangen. In the position of the upper wall part 6 near the passage opening 9 shown in FIG. 3A, a medium can flow from the inside of the container 2 along the arrows through openings 214 in the sealing pin 11 into the interior of the cylinder part 213 and from there through the sleeve part 212 via the passage opening 9 get outside.
