Definitions
- the invention relates to a tilt closure for containers containing flowable material according to the preamble of patent claim 1.
- a tilt lock of this type is known from DE-A-38 29 023.
- the pretensioning device is optionally connected to the closure cap or the cap cover and can consist of at least one curved member which either protrudes downward from the underside of the closure cap and interacts with an obliquely tapering surface of the cover plate or which protrudes from the cover plate and contacts abuts a sliding surface of the cap cover.
- the known pretensioning device develops its highest pretensioning force with increasing pivoting of the cap cover into the open position, while the restoring forces of the known pretensioning device are generally not sufficient to automatically bring the cap cover back into the closed position.
- the invention has for its object to improve the tilt lock according to the preamble of claim 1 so that the biasing device acts on the cap cover in each operating position with such a high biasing force that the cap cover from its open position automatically returned to the closed position.
- the biasing device consists of a V-shaped leaf spring, it is possible to give it such a width that this alone ensures a relatively high restoring force against changes in shape. It is essential, however, that the spring legs spread outward in the shape of a bow in the relaxed state in the closed position of the cap cover keep the latter under a relatively high pretensioning force. This is due to the fact that in this closed position of the cap lid essentially flat and parallel to each other spring legs are prevented by the adjacent hinge-like articulations of the leg ends on the cap lid or at the upper edge of the cap from returning to their relaxed, curved starting position.
- the ends of the two spring legs are expediently arranged in a plane which is directed approximately perpendicular to the bisector of the angle at the leg root.
- V-shaped leaf spring can be injection molded in one piece from plastic with the tilt closure. This facilitates economical mass production of the tilt lock.
- a tilt closure 10 which consists of a cylindrical closure cap 11 and a cap cover 12, which is inserted into a recess 50 in the closure cap 11.
- the cap 11 is made with the cap cover 12 by a biasing device 13 in one piece from plastic by injection molding.
- a lower part 14 of the closure cap 11 is separated from an upper part 15 by a cover plate 16.
- the cylindrical lower part 14 is provided with an internal thread 17, by means of which the closure cap 11 can be screwed onto the neck of an unillustrated container made of plastic, glass or the like provided with an external thread. In deviation from this type of fastening, the closure cap can of course also be snapped onto a container by means of a snap fit.
- the underside of the cover plate 16 is provided with a circular sealing lip 18 which extends to form an annular groove 19 at a distance from the inner wall of the closure cap 11 and which is sealingly and elastically applied to the opening edge of the container neck. Furthermore, the cover plate 16 is provided with a passage opening 20.
- the upper cap wall 24 is provided in FIGS. 1 and 2 at the level of the closed cap cover 12 and its outlet opening 25 with a spherical cap-shaped recess 26 on the inside of the cap wall 24, the radius of which corresponds to the distance of this recess 26 from a pivot axis 27 of the cap cover 12 .
- the side surface of the cap cover 12 is formed in the area of the outlet opening 25 in a manner corresponding to a spherical cap, so that the cap wall 24 seals the outlet opening 25 with elastic prestress when the cap cover 12 is closed.
- the pivot axis 27 of the cap lid is arranged offset with respect to a central longitudinal axis 28 of the closure cap 12 on the side opposite the outlet opening 25. Coaxial to the pivot axis 27, recesses 29 are provided on approximately diametrically opposite sides of the inside of the cap wall 24, into the guide pins 30 engage approximately diametrically opposite sides of the cap lid 12.
- a plurality of support beams 31 which are arranged on the inside of the cap wall 24 and whose upper ends form an arc-shaped support surface 32, the center of curvature of which is the pivot axis 27.
- the upper edge 23 of the upper part 15 of the closure cap 11 is provided with a cutout 33 on the side opposite the recess 26.
- the cap edge is articulated via a first hinge axis 34 to a leaf spring 35 corresponding to an inverted V in FIG. 3, which extends approximately 1/3 of the diameter of the cap cover symmetrically to a diametrical axis.
- a leg root 36 of the leaf spring is accordingly directed upward in FIG. 3, while the first and second legs 37, 38 are curved downward and widely spread in the relaxed state shown in FIGS. 3 and 4.
- the spring ends lie approximately in a horizontal plane which is directed perpendicular to the bisector of the angle at the leg root 36.
- the first leg 37 is articulated with a second hinge axis 39 to the edge of an essentially cylindrical cover shell 40, which projects from the underside of the cap cover 12.
- the cover jacket 40 is provided with a pair of support cheeks 41, the radius of which corresponds essentially to that of the support surface 32 in the upper part 24 of the closure cap 11 and enables the pivoting movement of the cap cover 12 between its closed and open positions.
- a closing member 43 is provided on the underside of the head plate 42, which in the outlet opening 22 of the Outlet connector 21 engages sealingly.
- a sealing cap 44 is provided on the underside, which on the side facing away from the outlet opening 25 tightly encloses the outlet connection 21 also in the open position of the cap cover 12, wherein, as shown in FIGS. 1 and 3, the sealing cap the side facing the outlet opening lies below an outlet channel 45 which connects the outlet opening 25 to the outlet nozzle 21 and, in the open position of the cap lid 12, via the latter to the interior of the container.
- the closing member 43 In the open position, the closing member 43 is located outside the outlet opening 22, so that the container contents can escape into the open through the outlet opening 22 into the outlet channel 45 and through the outlet opening 25 then located above the upper cap edge 23.
- the V-shaped leaf spring 35 is arranged in the closed position of the cap cover 12 so that the second hinge axis 39 is adjacent to the first hinge axis 34, and the first and second legs 37, 38 largely flat and parallel to each other against their spreading force are directed in the direction of the outlet opening 25 and the cover plate 16, the leg root 36 resting on the top of the cover plate 16.
- the biasing force exerted by this deformation of the first and second legs 37, 38 curved in its relaxed starting position according to FIG. 3 is naturally absorbed by the guide pins 30 of the cap cover 12 and the outlet connection 21. If the cap cover 12 is pivoted clockwise in FIG.
- the outlet opening 25, as shown in FIG. 5, is open above the upper edge of the cap 23. This takes place with an arcuate downward movement of the second hinge axis 39 on the cap cover 12.
- the entire leaf spring 35 is pressurized in the direction of the inside of the cap wall 24 adjacent to it, whereby the first leg 37 bends inwards with increasing pretension, while the second leg 38 is bent outwards, as FIG. 5 clearly shows.
- the leaf spring 35 exerts an increasing pretensioning force on the cap lid 12 in its closing direction and tends to pivot the cap lid 12 back into the closed position according to FIG. 1 when it is released by the operator, due to the deformation of the originally curved first and second legs 37, 38 is so great that the cap cover 12 always returns to its closed position with certainty.

Description
Die Erfindung betrifft einen Kippverschluß für fließfähiges Gut enthaltende Behälter gemäß dem Oberbegriff des Patentanspruchs 1.The invention relates to a tilt closure for containers containing flowable material according to the preamble of patent claim 1.
Ein Kippverschluß dieser Bauart ist aus der DE-A-38 29 023 bekannt. Bei diesem Kippverschluß ist die Vorspannvorrichtung wahlweise mit der Verschlußkappe oder dem Kappendeckel verbunden und kann aus mindestens einem gebogenen Organ bestehen, das entweder von der Unterseite der Verschlußkappe nach unten vorsteht und mit einer schräg zulaufenden Fläche der Abdeckplatte zusammenwirkt oder das von der Abdeckplatte hochragt und an einer Gleitfläche des Kappendeckels anliegt. Die bekannte Vorspannvorrichtung entwickelt ihre höchste Vorspannkraft mit zunehmender Verschwenkung des Kappendeckels in die Öffnungsstellung, während die Rückstellkräfte der bekannten Vorspannvorrichtung in der Regel nicht ausreichen, um den Kappendeckel selbsttätig in die Schließstellung zurückzubringen.A tilt lock of this type is known from DE-A-38 29 023. In this tilt closure, the pretensioning device is optionally connected to the closure cap or the cap cover and can consist of at least one curved member which either protrudes downward from the underside of the closure cap and interacts with an obliquely tapering surface of the cover plate or which protrudes from the cover plate and contacts abuts a sliding surface of the cap cover. The known pretensioning device develops its highest pretensioning force with increasing pivoting of the cap cover into the open position, while the restoring forces of the known pretensioning device are generally not sufficient to automatically bring the cap cover back into the closed position.
Der Erfindung liegt die Aufgabe zugrunde, den Kippverschluß gemäß dem Oberbegriff des Anspruchs 1 so zu verbessern, daß die Vorspannvorrichtung den Kappendeckel in jeder Betriebsstellung desselben mit einer derart hohen Vorspannkraft beaufschlagt, daß der Kappendeckel aus seiner Offenstellung selbsttätig in die Schließstellung vollständig zurückgebracht wird.The invention has for its object to improve the tilt lock according to the preamble of claim 1 so that the biasing device acts on the cap cover in each operating position with such a high biasing force that the cap cover from its open position automatically returned to the closed position.
Die Erfindung löst diese Aufgabe durch die im Kennzeichen des Patentanspruchs 1 enthaltenen Merkmale.The invention solves this problem by the features contained in the characterizing part of patent claim 1.
Dadurch, daß die Vorspannvorrichtung aus einer V-förmigen Blattfeder besteht, ist es möglich, dieser eine solche Breite zu geben, daß allein hierdurch eine relativ hohe Rückstellkraft gegenüber Formänderungen sichergestellt wird. Wesentlich ist aber, daß die im entspannten Zustand bogenförmig nach außen gespreizten Federschenkel in der Schließstellung des Kappendeckels diesen unter einer verhältnismässig hohen Vorspannkraft halten. Dies beruht darauf, daß die in dieser Schließstellung des Kappendeckels im wesentlichen ebenflächig und parallel zueinander verlaufenden Federschenkel durch die benachbarten scharnierartigen Anlenkungen der Schenkelenden am Kappendeckel bzw. am oberen Rand der Verschlußkappe daran gehindert werden, ihre entspannte, gekrümmte Ausgangsstellung wieder einzunehmen. Infolgedessen wird auf die Unterseite der der Auslaßöffnung gegenüberliegenden Seite des Kappendeckels selbst noch in der Schließstellung desselben eine so große Vorspannkraft ausgeübt, daß der Kappendeckel beim Loslassen desselben in der Öffnungsstellung mit Sicherheit selbsttätig die Schließlage einnimmt. Soll der Kappendeckel aus der Schließstellung in die Öffnungsstellung durch Ausübung eines Fingerdrucks auf die der Auslaßöffnung gegenüberliegenden Seite des Kappendeckels verschwenkt werden, dann wird die Verbindungsstelle zwischen Kappendeckel und dem zugehörigen Schenkelende in Richtung der Schenkelwurzel der V-Feder sowie gegen den mit dem Kappenrand verbundenen anderen Schenkel bewegt, wobei der mit dem Kappendeckel verbundene Schenkel sich nach der dem anderen Schenkel entgegengesetzten Seite auswölbt, so daß die Rückstellkraft der Feder sich vergrößert.Characterized in that the biasing device consists of a V-shaped leaf spring, it is possible to give it such a width that this alone ensures a relatively high restoring force against changes in shape. It is essential, however, that the spring legs spread outward in the shape of a bow in the relaxed state in the closed position of the cap cover keep the latter under a relatively high pretensioning force. This is due to the fact that in this closed position of the cap lid essentially flat and parallel to each other spring legs are prevented by the adjacent hinge-like articulations of the leg ends on the cap lid or at the upper edge of the cap from returning to their relaxed, curved starting position. As a result, such a large pretensioning force is exerted on the underside of the side of the cap cover opposite the outlet opening even in the closed position that the cap cover assumes the closed position automatically when it is released in the open position. If the cap cover is to be pivoted from the closed position into the open position by exerting a finger pressure on the side of the cap cover opposite the outlet opening, then the connection point between the cap cover and the associated leg end is directed in the direction of the leg root of the V-spring and against the other connected to the cap edge Leg moves, the leg connected to the cap lid bulging toward the opposite side of the other leg, so that the restoring force of the spring increases.
Zweckmäßig sind in der entspannten Stellung die Enden der beiden Federschenkel in einer Ebene angeordnet, die etwa senkrecht zur Winkelhalbierenden des Winkels an der Schenkelwurzel gerichtet ist.In the relaxed position, the ends of the two spring legs are expediently arranged in a plane which is directed approximately perpendicular to the bisector of the angle at the leg root.
Ferner kann die V-förmige Blattfeder mit dem Kippverschluß einteilig aus Kunststoff spritzgegossen sein. Dies erleichtert eine wirtschaftliche Massenfertigung des Kippverschlusses.Furthermore, the V-shaped leaf spring can be injection molded in one piece from plastic with the tilt closure. This facilitates economical mass production of the tilt lock.
Die Erfindung ist nachstehend anhand der schematischen Zeichnung eines Ausführungsbeispiels näher erläutert.The invention is explained below with reference to the schematic drawing of an embodiment.

In den Figuren ist ein Kippverschluß 10 gezeigt, der aus einer zylindrischen Verschlußkappe 11 und einem Kappendekkel 12 besteht, der in eine Aussparung 50 in der Verschlußkappe 11 eingesetzt ist. Die Verschlußkappe 11 ist mit dem Kappendeckel 12 durch eine Vorspannvorrichtung 13 einteilig aus Kunststoff durch Spritzgießen hergestellt.In the figures, a
Ein Unterteil 14 der Verschlußkappe 11 ist von einem Oberteil 15 durch eine Abdeckplatte 16 getrennt.A
Der zylindrische Unterteil 14 ist mit einem Innengewinde 17 versehen, mittels welchem die Verschlußkappe 11 auf den mit einem Außengewinde versehenen Hals eines nicht dargestellten Behälters aus Kunststoff, Glas oder dgl. aufgeschraubt werden kann. In Abweichung von dieser Befestigungsart kann die Verschlußkappe naturgemäß auch auf einen Behälter mittels Schnappsitz aufgeprellt werden. Die Unterseite der Abdeckplatte 16 ist mit einer kreisförmigen Dichtlippe 18 versehen, die sich unter Bildung einer Ringnut 19 im Abstand von der Innenwandung von der Verschlußkappe 11 erstreckt und sich an den Öffnungsrand des Behälterhalses abdichtend und elastisch anlegt. Ferner ist die Abdeckplatte 16 mit einer Durchlaßöffnung 20 versehen.The cylindrical
Über der Durchlaßöffnung 20 ragt in den Oberteil 15 der Verschlußkappe 11 ein Austrittsstutzen 21 nach oben, dessen obere Austrittsöffnung 22 mit Abstand unterhalb eines oberen Randes 23 einer zylindrischen Kappenwand 24 des Oberteils 15 angeordnet ist.Extending above the passage opening 20 into the
Die obere Kappenwand 24 ist in den Fig. 1 und 2 in Höhe des geschlossenen Kappendeckels 12 und dessen Auslaßöffnung 25 mit einer kugelkalottenförmigen Vertiefung 26 an der Innenseite der Kappenwand 24 versehen, deren Radius dem Abstand dieser Vertiefung 26 von einer Schwenkachse 27 des Kappendeckels 12 entspricht. Die Seitenfläche des Kappendeckels 12 ist im Bereich der Auslaßöffnung 25 entsprechend kugelkalottenartig ausgebildet, so daß die Kappenwand 24 die Auslaßöffnung 25 mit elastischer Vorspannung abdichtet, wenn der Kappendeckel 12 geschlossen ist.The
Die Schwenkachse 27 des Kappendeckels ist gegenüber einer Mittellängsachse 28 der Verschlußkappe 12 nach der der Auslaßöffnung 25 entgegengesetzten Seite versetzt angeordnet. Koaxial zur Schwenkachse 27 sind an etwa diametral gegenüberliegenden Seiten der Innenseite der Kappenwand 24 Vertiefungen 29 vorgesehen, in die Führungszapfen 30 an etwa diametral gegenüberliegenden Seiten des Kappendeckels 12 eingreifen.The
Unterhalb dieser Vertiefungen 29 befinden sich mehrere Stützbalken 31, die an der Innenseite der Kappenwand 24 angeordnet sind und deren obere Enden eine kreisbogenförmige Stützfläche 32 bilden, deren Krümmungsmittelpunkt die Schwenkachse 27 ist.Below these
Der obere Rand 23 des Oberteils 15 der Verschlußkappe 11 ist an der der Vertiefung 26 gegenüberliegenden Seite mit einem Ausschnitt 33 versehen. Im tiefsten Bereich dieses Ausschnittes 33 ist der Kappenrand über eine erste Scharnierachse 34 an eine in Fig. 3 einem umgekehrten V entsprechende Blattfeder 35 angelenkt, die sich etwa über 1/3 des Durchmessers des Kappendeckels symmetrisch zu einer diametralen Achse erstreckt. Eine Schenkelwurzel 36 der Blattfeder ist demnach in Fig. 3 nach oben gerichtet, während der erste und zweite Schenkel 37, 38 in dem in Fig. 3 und 4 gezeigten entspannten Zustand nach unten gewölbt und weit gespreizt sind. Dabei liegen die Federenden etwa in einer horizontalen Ebene, die senkrecht zur Winkelhalbierenden des Winkels an der Schenkelwurzel 36 gerichtet ist. Der erste Schenkel 37 ist mit einer zweiten Scharnierachse 39 an den Rand eines im wesentlichen zylindrischen Deckelmantels 40 angelenkt, der von der Unterseite des Kappendeckels 12 vorsteht.The
Im Bereich der Führungszapfen 30 des Kappendeckels 12 ist der Deckelmantel 40 mit einem Paar Stützwangen 41 versehen, deren Radius demjenigen der Stützfläche 32 im Oberteil 24 der Verschlußkappe 11 im wesentlichen entspricht und die Schwenkbewegung des Kappendeckels 12 zwischen seiner Schließ- und Offenstellung ermöglicht.In the area of the
Ferner ist an der Unterseite der Kopfplatte 42 ein Schließorgan 43 vorgesehen, das in die Austrittsöffnung 22 des Austrittstutzens 21 abdichtend eingreift. In radialem Abstand von diesem Schließorgan 43 ist an der Unterseite eine Dichtkappe 44 vorgesehen, die an der der Auslaßöffnung 25 abgekehrten Seite den Austrittsstutzen 21 auch in der Öffnungsstellung des Kappendeckels 12 dicht umschließt, wobei, wie Fig. 1 und 3 zeigen, die Dichtkappe auf der der Auslaßöffnung zugekehrten Seite unterhalb eines Auslaßkanals 45 liegt, der die Auslaßöffnung 25 mit dem Austrittsstutzen 21 und in der Öffnungsstellung des Kappendeckels 12 über diesen mit dem Behälterinneren verbindet. In der Öffnungsstellung befindet sich das Schließorgan 43 außerhalb der Austrittsöffnung 22, so daß der Behälterinhalt durch die Austrittsöffnung 22 in den Auslaßkanal 45 sowie durch die dann oberhalb des oberen Kappenrandes 23 liegende Auslaßöffnung 25 ins Freie austreten kann.Furthermore, a
Wie Fig. 1 zeigt, ist die V-förmige Blattfeder 35 in der Schließstellung des Kappendeckels 12 so angeordnet, daß die zweite Scharnierachse 39 der ersten Scharnierachse 34 benachbart ist, und erster und zweiter Schenkel 37, 38 entgegen ihrer Spreizkraft weitgehend ebenflächig und parallel zueinander in Richtung der Auslaßöffnung 25 sowie der Abdeckplatte 16 gerichtet sind, wobei die Schenkelwurzel 36 auf der Oberseite der Abdeckplatte 16 aufliegt. Die durch diese Verformung der in ihrer entspannten Ausgangsstellung gemäß Fig. 3 gekrümmten ersten und zweiten Schenkel 37, 38 ausgeübte Vorspannkraft wird naturgemäß von den Führungszapfen 30 des Kappendeckels 12 und dem Austrittsstutzen 21 aufgenommen. Wird durch Ausübung eines Fingerdrucks auf die Vertiefung (Betätigungsorgan 46) einer Kopfplatte 47 der Kappendeckel 12 in Fig. 1 in Uhrzeigerrichtung verschwenkt, liegt die Auslaßöffnung 25, wie Fig. 5 zeigt, oberhalb des oberen Kappenrandes 23 offen. Dies geschieht unter einer bogenförmigen Abwärtsbewegung der zweiten Scharnierachse 39 am Kappendeckel 12. Dabei wird die gesamte Blattfeder 35 in Richtung der ihr benachbarten Innenseite der Kappenwand 24 mit Druck beaufschlagt, wobei der erste Schenkel 37 sich mit zunehmender Vorspannung nach innen ausbiegt, während der zweite Schenkel 38 nach außen weggebogen wird, wie Fig. 5 deutlich zeigt. Infolgedessen übt die Blattfeder 35 eine sich verstärkende Vorspannkraft auf den Kappendeckel 12 in dessen Schließrichtung aus und hat das Bestreben, den Kappendeckel 12, wenn dieser von der Bedienungsperson losgelassen wird, sofort wieder in die Schließstellung gemäß Fig. 1 zurückzuschwenken, wobei die durch die Verformung der ursprünglich gekrümmten ersten und zweiten Schenkel 37, 38 hervorgerufene Vorspannkraft so groß ist, daß der Kappendeckel 12 mit Sicherheit immer seine Schließstellung wieder einnimmt.As shown in Fig. 1, the V-
