The sealing pin (5) is fitted at the inner end of the pouring nozzle (6) and outside the flow path (A) in such a way that, when the pouring nozzle (6) is pivoted into the second position, a region of the folding wall (10) is pressed into the inner end region of the through passage (7) by the sealing pin (5).

Description

Die Erfindung betrifft einen Verschluss für Behälter oder dgl.. Die Erfindung bezieht sich damit insbesondere auf einteilige Kipphebelverschlüsse, die zum auslaufsicheren Verschliessen von Behältern und Flaschen zur Bevorratung von Flüssigkeiten aller Art geeignet sind.The invention relates to a closure for containers or the like. The invention therefore relates in particular to one-piece rocker arm closures which are suitable for leak-proof closing of containers and bottles for storing liquids of all kinds.

Ein Verschluss dieser Art ist aus der DE-A-31 04 561 bekannt. Bei dem bekannten Verschluss wird eine schwenkbare Ausgiesstülle in der Schliesstellung durch einen in das äussere Ende einer Durchgangsöffnung in der Ausgiesstülle eingreifenden Dichtvorsprung abgedichtet, der an einer aussenliegenden Endwand einer im Kappenteil vorgesehenen Ausnehmung nach innen ragend angeformt ist, in der die Ausgiesstülle in der Schliesstellung im wesentlichen aufgenommen ist. Zwar kann der Dichtvorsprung zusätzlich die Funktion der Arretierung der Ausgiesstülle in der Schliesstellung übernehmen, so dass diesbezügliche gesonderte Massnahmen eingespart werden können, doch werden stärkere Verschmutzungen der Ausnehmung im Kappenteil nicht zu vermeiden sein, da der Dichtvorsprung dem abzudichtenden Fluid ausgesetzt ist und abtropfendes oder durch Leckverluste ausgetretenes Fluid sich in der Ausnehmung ansammeln und wegen der erforderlichen aussenliegenden Endwand nicht ohne weiteres abfliessen kann. Aus der DE-C-32 02 151 ist es ferner bekannt, die Durchgangsöffnung in der Ausgiesstülle statt am äusseren Ende an deren inneren eintrittsseitigen Ende abzudichten. Hierzu ist längs des inneren Endes der Durchgangsöffnung eine Dichtlippe vorgesehen, die bei der Schwenkung der Ausgiesstülle in die Schliesstellung gegen eine am Kappenteil vorgesehene starre Wand gedrückt wird. Die Dichtwirkung dieser Massnahme ist daher stark abhängig von der Kraft, mit der die Ausgiesstülle gegen die Wandung gedrückt wird, was eine für niedrig viskose Flüssigkeiten häufig nicht ausreichende Dichtwirkung zur Folge haben kann. Darüber hinaus sind gesonderte Mittel vorzusehen, um die Ausgiesstülle in der Schliesstellung zu halten. Demzufolge sind bei einem Verschluss ähnlicher Ausbildung, wie er aus der EP-B-0 280 142 bekannt ist, Raststege in der Ausnehmung im Kappenteil vorgesehen, die Rastleisten an der Ausgiesstülle hintergreifen können. Vorteil der bekannten innerendigen Abdichtung der Durchgangsöfffnung der Ausgiesstülle ist jedoch, dass hinsichtlich der Ausbildung der die Ausgiesstülle aufnehmenden Ausnehmung weniger Einschränkungen als bei Verschlüssen mit aussenseitiger Abdichtung der Durchgangspassage vorliegen, da grundsätzlich auf eine aussenseitige Endwand der Ausnehmung verzichtet werden kann.A closure of this type is known from DE-A-31 04 561. In the known closure, a pivotable pouring spout is sealed in the closed position by a sealing projection which engages in the outer end of a through opening in the pouring spout and which is integrally formed on an outer end wall of a recess provided in the cap part, in which the pouring spout in the closed position in the is essentially included. Although the sealing projection can also take on the function of locking the pouring spout in the closed position, so that separate measures in this regard can be dispensed with, greater contamination of the recess in the cap part cannot be avoided since the sealing projection is exposed to the fluid to be sealed and drips or through Leakage leaked fluid can accumulate in the recess and cannot easily flow away due to the required outer end wall. From DE-C-32 02 151 it is further known to seal the through opening in the pouring spout instead of at the outer end at the inner inlet end thereof. For this purpose, a sealing lip is provided along the inner end of the through opening, which is pressed against a rigid wall provided on the cap part when the pouring spout is pivoted into the closed position. The sealing effect of this measure is therefore strongly dependent on the force with which the pouring spout is pressed against the wall, which can often result in a sealing effect which is insufficient for low-viscosity liquids. In addition, separate means must be provided to keep the pouring spout in the closed position. Accordingly, with a closure of a similar design, as is known from EP-B-0 280 142, latching webs are provided in the recess in the cap part, which can engage behind latching bars on the pouring spout. An advantage of the known internal sealing of the through opening of the pouring spout is, however, that there are fewer restrictions with regard to the design of the recess receiving the pouring spout than with closures with an external sealing of the passage passage, since in principle there is no need for an outside end wall of the recess.

Der Erfindung liegt die Aufgabe zugrunde, einen Verschluss der eingangs erwähnten Gattung zu schaffen, der bei einfachem fertigungsgünstigem Aufbau und verringerter Anfälligkeit gegen Verschmutzung eine verbesserte Abdichtung der Durchgangspassage der Ausgiesstülle ermöglicht.The invention has for its object to provide a closure of the type mentioned, which allows an improved sealing of the passage passage of the pouring spout with a simple construction favorable construction and reduced susceptibility to contamination.

Der erfindungsgemässe Verschluss umfasst einen auf den Behälter aufbringbaren Kappenteil mit einer Ausgiesstülle, die zur Verschwenkung zwischen einer ersten und zweiten Stellung innerends umfänglich mit dem Kappenteil durch ein Filmscharnier und im übrigen durch eine flexible Faltwand einstückig verbunden ist und eine Durchgangspassage als Teil eines Strömungsweges zwischen dem Inneren des Kappenteiles und der Aussenseite aufweist, welche Durchgangspassage in der ersten Stellung der Ausgiesstülle geöffnet und in der zweiten Stellung durch einen in einen Endbereich der Durchgangspassage eingreifenden Dichtzapfen abgedichtet ist, der am Kappenteil in einer in Bezug auf die zweite Stellung der Ausgiesstülle im wesentlichen ausgerichteten Beziehung zur Durchgangspassage angeordnet ist, wobei der Dichtzapfen innerendseitig der Ausgiesstülle und ausserhalb des Strömungsweges vorgesehen ist, dergestalt dass bei der Schwenkung der Ausgiesstülle in die zweite Stellung ein Bereich der Faltwand durch den Dichtzapfen in den inneren Endbereich der Durchgangspassage eindrückbar ist.The closure according to the invention comprises a cap part which can be applied to the container and has a pouring spout which, for pivoting between a first and a second position, extends circumferentially with the cap part Film hinge and otherwise connected in one piece by a flexible folding wall and has a passage passage as part of a flow path between the inside of the cap part and the outside, which passage passage is opened in the first position of the pouring spout and in the second position by an engaging in an end region of the passage passage Sealing pin is sealed, which is arranged on the cap part in a relation to the passage passage that is essentially aligned with respect to the second position of the pouring spout, the sealing pin being provided on the inside of the pouring spout and outside the flow path, in such a way that when the pouring spout is pivoted into the second position an area of the folding wall can be pressed into the inner end area of the passage passage through the sealing pin.

Erfindungsgemäss übernimmt somit der Dichtzapfen nicht nur die Funktion des Abdichtens der Durchgangspassage der Ausgiesstülle, sondern auch deren Arretierung in der Schliesstellung, so dass auf zusätzliche Arretierungs- oder Rastmittel verzichtet werden kann, was den Aufbau des Verschlusses entsprechend vereinfacht. Der Dichtzapfen greift in den inneren Endbereich der Durchgangspassage ein uzw. unter Einbeziehung der Faltwand als weiteres Abdichtungsmittel, indem ein Bereich der Faltwand bei der Bewegung der Ausgiesstülle in die Schliesstellung in das innere Ende der Durchgangspassage hineingedrückt wird. Dies schafft gleichzeitig eine erhöhte Dichtwirkung und vermeidet ein Verschmutzen des Dichtzapfens, da dieser mit dem abzudichtenden Fluid nicht in Berührung kommt. Wegen der innerendigen Abdichtung der Durchgangspassage kann, wenn erwünscht, auf eine äussere Abschlusswand der Ausnehmung im Kappenteil, welche die Ausgiesstülle in der Schliesstellung aufnimmt, verzichtet werden, was ebenfalls dazu beiträgt, dass Ansammlungen von verschmutzendem Fluid in der Ausnehmung vermieden werden. Anders als bei den meisten bekannten Verschlüssen sind an das Faltverhalten der Faltwand keine speziellen Anforderungen zu stellen, so dass die Faltwand, wenn erwünscht, ohne vorgegebene Knick- oder Faltlinien als einfache Wandverdünnung ausgebildet werden kann. Der Verschluss nach der Erfindung zeichnet sich daher insgesamt durch eine verbesserte Funktionalität als auch vereinfachte Fertigungsmöglichkeit aus und ist darüber hinaus leicht an verschiedene Anwendungsfälle gestalterisch anpassbar. Bezüglich Weiterbildungen der Erfindung wird auf die Unteransprüche verwiesen.According to the invention, the sealing pin therefore not only assumes the function of sealing the passage of the pouring spout, but also locking it in the closed position, so that additional locking or latching means can be dispensed with, which correspondingly simplifies the construction of the closure. The sealing pin engages in the inner end region of the passage passage. with the inclusion of the folding wall as a further sealing means, in that a region of the folding wall is pressed into the inner end of the passage passage when the pouring spout moves into the closed position. At the same time, this creates an increased sealing effect and prevents the sealing pin from becoming dirty, since it does not come into contact with the fluid to be sealed. Because of the internal sealing of the passage passage, if desired, an outer end wall of the recess in the cap part, which receives the pouring spout in the closed position, can be dispensed with, which also contributes to that accumulations of polluting fluid in the recess are avoided. In contrast to most known closures, there are no special requirements for the folding behavior of the folding wall, so that the folding wall can, if desired, be designed as a simple wall thinning without predetermined folding or folding lines. The closure according to the invention is therefore characterized overall by an improved functionality as well as a simplified production possibility and, moreover, can be easily adapted in terms of design to various applications. With regard to developments of the invention, reference is made to the subclaims.

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

  • Fig. 2 eine geschnittene Ansicht längs der Schnittlinie II-II in Fig. 1,
  • Fig. 3 den Verschluss in einer Ansicht ähnlich Fig. 2, jedoch mit Darstellung der Ausgiesstülle in einer zweiten oder Schliesstellung, und
  • Fig. 4 eine geschnittene Ansicht längs der Schnittlinie IV-IV in Fig. 3.
The invention is explained in more detail below using an embodiment and the drawing. Show it:
  • 1 is a perspective view of a closure constructed according to the invention, showing the pouring spout in a first or open position,
  • 2 shows a sectional view along the section line II-II in FIG. 1,
  • Fig. 3 shows the closure in a view similar to Fig. 2, but showing the pouring spout in a second or closed position, and
  • 4 shows a sectional view along the section line IV-IV in FIG. 3.

Der Verschluss nach der Erfindung umfasst, wie dargestellt, einen an einem Hals eines Behälters oder einer Flasche (nicht gezeigt) in geeigneter Weise, z.B. mittels eines in Fig. 2 gezeigten Schraubgewindes 13, befestigbaren Kappenteil 1 mit einer Oberwand 2 und einem inneren Dichtkonus 11, der dichtend in die Mündungsöffnung des Behälterhalses eingreifen kann. Alternativ kann der Kappenteil 1 auch in bekannter Weise Mittel zum Aufprellen auf einen Behälterhals aufweisen. Die Oberwand 2 bildet eine nach aussen und nach oben offene Ausnehmung 3, deren längere Achse radial zur Mittellinie steht und die im übrigen auf die Abmessung und Konfiguration einer nachfolgend beschriebenen am Kappenteil 1 angebundenen Ausgiesstülle 6 angepasst ist, so dass diese in der Ausnehmung 3 aufgenommen werden kann.As shown, the closure according to the invention also includes a cap part 1 which can be fastened to a neck of a container or a bottle (not shown) in a suitable manner, for example by means of a screw thread 13 shown in FIG. 2 an upper wall 2 and an inner sealing cone 11 which can engage sealingly in the mouth of the container neck. Alternatively, the cap part 1 can also have means for impinging on a container neck in a known manner. The upper wall 2 forms a recess 3 which is open towards the outside and upwards, the longer axis of which is radial to the center line and which is moreover adapted to the dimensions and configuration of a pouring spout 6 which is connected to the cap part 1 and is described below, so that it is received in the recess 3 can be.

Die Ausgiesstülle 6 kann eine steife plattenförmige Deckwand 8 umfassen, an deren Unterseite eine röhrförmige Ausformung mit einer Durchgangspassage 7 mit einem inneren und einem äusseren Ende vorgesehen ist. Die Deckwand 8 ist längs ihrer inneren Breitseite über ein Filmscharnier 9 einstückig mit der Oberwand 2 des Kappenteiles 1 verbunden und ermöglicht somit, dass die Ausgiesstülle 6 relativ zum Kappenteil 1 zwischen zwei Endstellungen geschwenkt werden kann, worauf nachfolgend noch näher eingegangen wird.The pouring spout 6 can comprise a rigid plate-shaped cover wall 8, on the underside of which a tubular shape with a passage passage 7 with an inner and an outer end is provided. The top wall 8 is connected in one piece along its inner broad side via a film hinge 9 to the top wall 2 of the cap part 1 and thus enables the pouring spout 6 to be pivoted between two end positions relative to the cap part 1, which will be discussed in more detail below.

Eine weitere Verbindung zwischen der Ausgiesstülle 6 und dem Kappenteil 1 ist durch eine biegsame Wandverdünnung oder Faltwand 10 geschaffen, die sich einerseits zwischen einer inneren Kante 14 der Ausgiesstülle 6 und einer äusseren Kante 15 eines inneren Endwandbereiches 4 der Ausnehmung 3 im Kappenteil 1 sowie andererseits beidseitig des Filmscharnieres 9 umfänglich erstreckt. Die Faltwand 10 umgibt zusammen mit dem Filmscharnier 9 einen nach aussen hermetisch abgeschirmten Bereich, der Teil eines die Durchgangspassage 7 umfassenden Strömungsweges ist, vgl. Pfeile A in Fig. 2, der das Innere des Kappenteiles 1 bzw. des Behälters mit der Aussenumgebung verbindet, wenn sich die Ausgiesstülle 6 in der in Fig. 1 und 2 gezeigten ersten Stellung befindet. In dieser Stellung kann die Durchgangspassage 7 der Ausgiesstülle 6 auf einer Verlängerung der Mittellinie des Verschlusses liegen.A further connection between the pouring spout 6 and the cap part 1 is created by a flexible wall thinning or folding wall 10, which is on the one hand between an inner edge 14 of the pouring spout 6 and an outer edge 15 of an inner end wall area 4 of the recess 3 in the cap part 1 and on the other hand on both sides of the film hinge 9 extends circumferentially. The folding wall 10, together with the film hinge 9, surrounds an area which is hermetically shielded from the outside and which is part of a flow path comprising the passage 7, cf. Arrows A in Fig. 2, which connects the inside of the cap part 1 or the container with the outside when the pouring spout 6 in the first shown in Figs. 1 and 2 Position. In this position, the passage 7 of the pouring spout 6 can lie on an extension of the center line of the closure.

Die Faltwand 10 ist in der ersten Stellung der Ausgiesstülle 6 gestreckt und kann sich bei der Schwenkung der Ausgiesstülle 6 in die zweite in Fig. 3 und 4 gezeigte Stellung mehrfach falten. Wenn erwünscht, kann die Faltung in definierter Weise durch in der Faltwand 10 vorgegebene Knicklinien erfolgen. Da die Formung des Verschlusses in der in Fig. 1 und 2 gezeigten ersten Stellung mit gestreckter Faltwand 10 erfolgt, hat diese das Bestreben, die erste Stellung einzunehmen, wenn keine äussere Kraft auf die Ausgiesstülle 6 einwirkt.The folding wall 10 is stretched in the first position of the pouring spout 6 and can fold several times when the pouring spout 6 is pivoted into the second position shown in FIGS. 3 and 4. If desired, the folding can be carried out in a defined manner by means of folding lines predetermined in the folding wall 10. Since the closure is formed in the first position shown in FIGS. 1 and 2 with the folding wall 10 extended, the latter tends to assume the first position when no external force acts on the pouring spout 6.

Nachfolgend wird auf Fig. 3 und 4 näher Bezug genommen, die die Ausgiesstülle 6 in der zweiten oder Schliesstellung zeigen. In dieser Stellung ist die Ausgiesstülle 6 im wesentlichen in der Ausnehmung 3 des Kappenteiles 1 aufgenommen, wobei die Deckwand 8 im wesentlichen mit der Oberwand 2 des Kappenteiles 1 fluchtet. Ausserdem ist in dieser Stellung, wie vorerwähnt, der Strömungsweg A verschlossen. Hierzu ist an dem inneren Endwandbereich 4 der Ausnehmung 3 ein kugelkalottenartiger Dichtvorsprung oder - zapfen 5 angeformt, der in die Ausnehmung 3 hineinragt und in Bezug auf die Durchgangspassage 7 so ausgerichtet ist, dass er dichtend in deren inneren Endbereich eingreifen kann, wenn die Ausgiesstülle 6 von der ersten in die zweite Stellung geschwenkt wird. Am innere Endwandbereich 4 der Ausnehmung 3 ist ferner, wie bei 15 angedeutet, die Faltwand 10 am Kappenteil 1 angebunden.3 and 4, which show the pouring spout 6 in the second or closed position. In this position, the pouring spout 6 is received essentially in the recess 3 of the cap part 1, the top wall 8 being substantially flush with the top wall 2 of the cap part 1. In addition, the flow path A is closed in this position, as mentioned above. For this purpose, a spherical cap-shaped sealing projection or pin 5 is formed on the inner end wall region 4 of the recess 3, which protrudes into the recess 3 and is aligned with respect to the passage passage 7 in such a way that it can engage sealingly in its inner end region when the pouring spout 6 is pivoted from the first to the second position. On the inner end wall area 4 of the recess 3, the folding wall 10 is also connected to the cap part 1, as indicated at 15.

Aufgrund der vorbeschriebenen Anordnung des Dichtzapfens 5 kommt dieser bei der Schwenkung der Ausgiesstülle 6 von der ersten in die zweite Stellung zunächst aussenseitig mit der Faltwand 10 in Berührung, so dass sich diese am Dichtzapfen 5 anlegt und bei weiterer Schwenkung der Ausgiesstülle 6 in die zweite Stellung zusammen mit dem Dichtzapfen 5 in den inneren Endbereich der Durchgangspassage 7 hineingedrückt wird. Der Dichtzapfen 5 kommt daher nicht in unmittelbare Berührung mit dem abzudichtenden Fluid, wodurch Verschmutzungen des Dichtzapfens 5 vermieden werden, und andererseits schafft die Einbeziehung der Faltwand 10 zur Abdichtung der Durchgangspassage 7 eine erhöhte Dichtwirkung gegenüber einem dichtenden Eingreifen des Dichtzapfens alleine.Due to the above-described arrangement of the sealing pin 5, this comes from the pivoting of the pouring spout 6 first into the second position on the outside in contact with the folding wall 10, so that it rests on the sealing pin 5 and, when the pouring spout 6 is pivoted further, is pressed into the second end together with the sealing pin 5 into the inner end region of the passage passage 7. The sealing pin 5 therefore does not come into direct contact with the fluid to be sealed, as a result of which contamination of the sealing pin 5 is avoided, and on the other hand, the inclusion of the folding wall 10 for sealing the passage passage 7 creates an increased sealing effect against a sealing engagement of the sealing pin alone.

Der Dichtzapfen 5 wirkt ferner als Rastmittel, um die Ausgiesstülle 6 in der zweiten Stellung zu halten. Zusätzlich könnten auch gesonderte Rastmittel zwischen den Seitenwänden der Ausnehmung 3 des Kappenteiles 1 und der Deckwand 8 der Ausgiesstülle 6 vorgesehen werden, um diese in der zweiten Stellung zu halten.The sealing pin 5 also acts as a locking means to hold the pouring spout 6 in the second position. In addition, separate latching means could also be provided between the side walls of the recess 3 of the cap part 1 and the top wall 8 of the pouring spout 6 in order to hold them in the second position.

In der zweiten Stellung der Ausgiesstülle 6 kann ferner deren innere Verbindungskante 14, längs der die Faltwand 10 angeformt ist, an dem inneren Endwandbereich 4 der Ausnehmung 3 bündig anliegen. Bei einer kreissegmentförmigen Querschnittskonfiguration der Ausgiesstülle 6 kann daher die Verbindungskante 14 einen im wesentlichen sichelförmigen Verlauf haben und ist der Endwandbereich 4 der Ausnehmung 3 entsprechend konvex gewölbt. Es versteht sich, dass auch andere einander angepasste Konfigurationen für die Verbindungskante 14 und den inneren Endwandbereich 4 vorgesehen werden können.In the second position of the pouring spout 6, its inner connecting edge 14, along which the folding wall 10 is formed, can also lie flush against the inner end wall region 4 of the recess 3. In the case of a cross-sectional configuration of the pouring spout 6 in the form of a segment of a circle, the connecting edge 14 can therefore have an essentially crescent-shaped course and the end wall region 4 of the recess 3 is curved in a correspondingly convex manner. It goes without saying that other mutually adapted configurations can also be provided for the connecting edge 14 and the inner end wall region 4.

Zur leichteren Handhabung des Verschlusses kann die Deckwand 8 der Ausgiesstülle 6 etwas über das äussere Ende der Durchgangspassage 7 hinaus verlängert sein, so dass eine Greiflasche 12 gebildet ist, die von einem Finger einer Hand zur Schwenkung der Ausgiesstülle 6 unterfasst werden kann.For easier handling of the closure, the top wall 8 of the pouring spout 6 can be extended somewhat beyond the outer end of the passage passage 7, so that a Gripping tab 12 is formed, which can be gripped by a finger of a hand for pivoting the pouring spout 6.

Der erfindungsgemässe Verschluss ist ein im Spritzgiessverfahren einstückig geformtes Kunststoffteil, wobei die Ausformung vorzugsweise in der in Fig. 1 und 2 gezeigten ersten Stellung der Ausgiesstülle 6 mit gestreckter Faltwand 10 erfolgt.The closure according to the invention is a plastic part molded in one piece in the injection molding process, the molding preferably taking place in the first position of the pouring spout 6 shown in FIGS. 1 and 2 with the folding wall 10 extended.
