Abstract

A self-closing valve assembly for installation in a dispensing opening of a container, a seal cap or the like, includes a first closure element having a domed wall portion of resilient material incorporating a passage-opening, said wall portion being resiliently deformable from a closed position into an open position under the influence of a first differential pressure force resulting from pressures acting on its opposite surfaces, and a second closure element having a domed wall portion for sealing the passage-opening when the first closure element is in its closed position. In order to balance the pressure prvailing in a container provided with the valve assembly when a pressure-increasing squeezing force is no longer exerted on the container, the second closure element is adapted to be brought out of its sealing relationship with the passage-opening in the first closure element under the influence of a second differential pressure force resulting from pressures acting on its opposite surfaces, said second differential pressure force being directed oppositely to said first differential pressure force.

Description

Selbstschliessende Ventilanordnung für eine Behälterspendeöffnung Self-closing valve arrangement for a container dispensing opening
Die Erfindung betrifft eine selbstschliessende Ventilanordnung zum Einbau in eine Spendeöffnung an einem Behälter, einer Verschlusskappe oder dgl ..The invention relates to a self-closing valve arrangement for installation in a dispensing opening on a container, a closure cap or the like.
Eine gattungsgemässe Ventilanordnung, integriert in einer Verschlusskappe, ist aus der DE-A-195 10 007 bekannt. Dabei ist ein membranartiges Schliesselement aus einem nachgiebigen Material mit einer zentralen, permanent offenen Durchtrittsoffnung zwischen Teilen der auf einen Behälterhals aufschraubbaren Verschlusskappe eingeklemmt. Das Schliesselement ist im Ruhezustand konkav gewölbt und liegt mit seiner Aussenseite an einem Dichtelement an, das stationär im Kappenteil gehalten ist, um die Durchtrittsoffnung zu verschliessen. Unter einem erhöhten Druck auf das Schliesselement seitens dessen dem Dichtelement zugewandten Oberfläche kann das Schliesselement vom Dichtelement abgehoben werden, so dass längs der Durchtrittsoffnung ein Medium aus einem Behälter strömen kann, auf dessen Hals die Verschlusskappe aufgeschraubt werden kann. Sobald die Druckkraft auf das Schliesselement weggenommen wird, nimmt dieses aufgrund der Elastizität des nachgiebigen Materials wieder die Ruhestellung unter Verschliessen der Durchtrittsoffnung ein. Andererseits ist das Schliesselement so im Kappenteil eingespannt, dass die Spannwirkung einen Durchtritts von Luft ermöglicht, wenn im Inneren des Behälters ein Unterdruck herrscht, um einen Druckausgleich zu bewirken. Die Druckausgleichsfunktion hängt somit von der Art ab, wie das Schliesselement im Kappenteil eingespannt ist und kann aufgrund der Elastizität des Schliesselements und der darauf wirkenden Klemmkräfte beeinträchtigt werden, so dass die Druckausgleichsfunktion nicht immer gewährleistet ist. Ausserdem können die Kanäle, längs denen die Belüftungsluft zum Druckausgleich strömen kann, bei Gebrauch leicht verstopfen, und kann dadurch die Druckausgleichsfunktion verlorengehen. Nachteilig ist ferner, dass die Abdichtung der Durchtrittsoffnung im Schliesselement durch ein starres flächiges Dichtelement erfolgt, so dass bei Ablagerungen oder Verschmutzungen der Dichtfläche die Dichtfunktion leicht beeinträchtigt werden kann.A generic valve arrangement, integrated in a closure cap, is known from DE-A-195 10 007. A membrane-like closing element made of a resilient material with a central, permanently open passage opening is clamped between parts of the closure cap that can be screwed onto a container neck. The closing element is concavely curved in the idle state and lies with its outside against a sealing element which is held stationary in the cap part in order to close the passage opening. Under increased pressure on the closing element on the part of the surface facing the sealing element, the closing element can be lifted off the sealing element, so that a medium can flow along the passage opening from a container, onto the neck of which the closure cap can be screwed. As soon as the pressure force on the closing element is removed, this resumes the rest position due to the elasticity of the resilient material, with the passage opening being closed. On the other hand, the closing element is clamped in the cap part so that the Clamping effect allows air to pass if there is a negative pressure inside the container in order to equalize the pressure. The pressure compensation function therefore depends on the manner in which the closing element is clamped in the cap part and can be impaired due to the elasticity of the closing element and the clamping forces acting on it, so that the pressure compensation function is not always guaranteed. In addition, the channels along which the ventilation air can flow to equalize the pressure can easily become blocked during use, and the pressure equalization function can be lost as a result. Another disadvantage is that the passage opening in the closing element is sealed by a rigid, flat sealing element, so that the sealing function can easily be impaired in the event of deposits or contamination of the sealing surface.
Aufgabe der Erfindung ist es, eine selbstschliessende Ventilanordnung der gattungsgemassen Art mit gewährleisteter Dicht- und Druckausgleichsfunktion bei gleichzeitig günstiger Fertigungsmöglichkeit zu schaffen.The object of the invention is to provide a self-closing valve arrangement of the generic type with a guaranteed sealing and pressure compensation function and at the same time an inexpensive production option.
Diese Aufgabe wird gelöst durch eine selbstschliessende Ventilanordnung zum Einbau in einer Spendeöffnung an einem Behälter, einer Verschlusskappe oder dgl., mit einem ersten Schliesselement mit einem, eine Durchtrittsoffnung enthaltenden Wandteil aus elastischem Material, das unter einer ersten Differenzdruckkraft aus auf seinen gegenüberliegenden Oberflächen wirkenden Drücken elastisch aus einer Schliess- in eine Freigabestellung verformbar ist, und einem zweiten Schliesselement zum Abdichten der Durchtrittsoffnung, wenn sich das erste Schliesselement in seiner Schliesstellung befindet, wobei erfindungsgemäss das zweite Schliesselement unter einer entgegen der ersten Differenzdruckkraft gerichteten zweiten Differenzdruckkraft aus auf seinen gegenüberliegenden Oberflächen wirkenden Drücken aus der abdichtenden Beziehung zur Durchtrittsoffnung des ersten Schliesselements bringbar ist. Demnach sieht die erfindungsgemässe Ventilanordnung statt eines starren zweiten Schliesselements ein solches vor, das wie das erste Schliesselement unter der Wirkung einer äusseren Differenzdruckkraft elastisch nachgeben und dadurch aus der dichtenden Beziehung zu der Durchtrittsoffnung im ersten Schliesselement gelangen kann, um zum Zwecke des Druckausgleichs Belüftungsluft aus der Umgebung in das Behälterinnere einströmen zu lassen. Sowohl das erste als auch zweite Schliesselement können membranartig gewölbte Wandteile umfassen und aus geeigneten Kunststoffmaterialien mit elastischer Eigenschaft, z.B. einem elastomeren Material, gebildet sein. Die Montage der Schliesselemente zu einer selbstschliessenden Ventilanordnung bereitet keine Schwierigkeiten, da die Druckausgleichsfunktion nicht von einer die Schliesselemente gegenseitig positionierenden Klemmkraft beeinträchtigt wird. Die Ventilanordnung nach der Erfindung lässt sich ferner leicht miniaturisieren und ausser in auf einen Behälterhals aufschraubbaren Verschlusskappen auch direkt in eine Spendeöffnung eines Behälters einfügen.This object is achieved by a self-closing valve arrangement for installation in a dispensing opening on a container, a closure cap or the like, with a first closing element with a wall part made of elastic material which contains a passage opening and which acts under a first differential pressure force from pressures acting on its opposite surfaces is elastically deformable from a closing position into a release position, and a second closing element for sealing the passage opening when the first closing element is in its closing position, the second closing element according to the invention under a second differential pressure force directed against the first differential pressure force can be brought from the sealing relationship to the passage opening of the first closing element from pressures acting on its opposite surfaces. Accordingly, the valve arrangement according to the invention provides, instead of a rigid second closing element, one which, like the first closing element, yields elastically under the action of an external differential pressure force and can thus pass from the sealing relationship to the passage opening in the first closing element in order to vent air from the for the purpose of pressure compensation Let the environment flow into the interior of the container. Both the first and the second closing element can comprise membrane-like curved wall parts and can be formed from suitable plastic materials with an elastic property, for example an elastomeric material. The assembly of the closing elements to form a self-closing valve arrangement presents no difficulties, since the pressure compensation function is not impaired by a clamping force that mutually positions the closing elements. The valve arrangement according to the invention can also be easily miniaturized and inserted directly into a dispensing opening of a container in addition to screw caps that can be screwed onto a container neck.
Die Erfindung wird nachfolgend anhand der Zeichnung und einer Ausführungsform näher erläutert. Es zeigen:The invention is explained below with reference to the drawing and an embodiment. Show it:
Fig. 1 in fragmentarischer, geschnittener Ansicht eine selbstschliessende Ventilanordnung nach der Erfindung im Ruhezustand nach Montage an einer Behälterspendeöffnung,1 is a fragmentary, sectional view of a self-closing valve arrangement according to the invention in the idle state after mounting on a container dispensing opening,

In Fig. 1 ist die das allgemeine Bezugszeichen 1 tragende selbstschliessende Ventilanordnung nach der Erfindung in einer eine Spendeöffnung 4 enthaltenen Wand 3 eines Behälters 2 oder einer Verschlusskappe oder dgl. gezeigt. Obschon andere Mittel zur Montage der Ventilanordnung 1 vorgesehen sein können, ist bei der vorliegenden Ausführungsform an der Behälterwand 3 konzentrisch zur Spendeöffnung 4 eine Rastflansch 5 mit einem Rastbund 6 an seinem freien Ende angeformt. Anstelle eines Rastflansches könnte auch eine Vielzahl umfänglich verteilt angeordneter Raststege vorgesehen sein.1 shows the self-closing valve arrangement according to the invention bearing the general reference number 1 in a wall 3 of a container 2 or a closure cap or the like which contains a dispensing opening 4. Although other means for mounting the valve arrangement 1 can be provided, in the present embodiment, a locking flange 5 is formed on the container wall 3 concentrically with the dispensing opening 4 with a locking collar 6 at its free end. Instead of a latching flange, a plurality of latching webs arranged circumferentially distributed could also be provided.
Die zwischen der Unterseite der Wand 3 und dem Rastbund 6 durch Klemmkraft gehaltene Ventilanordnung 1 umfasst ein erstes Schliesselement 7, ein zweites Schliesselement 8 sowie einen auf dem Ringbund 6 aufliegenden Stützring 13. Jedes Schliesselement 7, 8 umfasst einen äusseren verdickten ringförmigen Montagebereich 9 bzw. 10 und einen daran angeformten inneren membranartigen Wandteil 11, 12. Die membranartigen Wandteile 11, 12 haben im Ruhezustand eine aufeinander zugerichtet gewölbte Konfigurationen, wie dies in Fig. 1 gezeigt ist.The valve arrangement 1 held between the underside of the wall 3 and the locking collar 6 by clamping force comprises a first closing element 7, a second closing element 8 and a support ring 13 resting on the annular collar 6. Each closing element 7, 8 comprises an outer thickened annular assembly area 9 or 10 and an inner membrane-like wall part 11, 12 formed thereon. In the rest state, the membrane-like wall parts 11, 12 have a configuration which is curved toward one another, as shown in FIG. 1.
Eine Durchtrittsoffnung 14 ist im membranartigen Wandteil 11 des ersten, der Spendeöffnung 4 zugewandten Schliesselements 7 vorgesehen. Ein oder mehrere Durchtrittsöffnungen 15 im membranartigen Wandteil 12 des zweiten Schliesselements 8 schaffen eine Verbindung zwischen der Ober- und Unterseite des membranartigen Wandteils 12 an einer Stelle, die radial versetzt zu einem zentralen Bereich des Wandteils 12 liegt. Der zentrale Bereich des Wandteils 12 ist daher frei von Perforationen und damit geeignet, in der in Fig. 1 gezeigten Ruhestellung die zentrale Durchtrittsoffnung 14 des ersten Schliesselements 7 abzudichten, wenn die Kuppen der gewölbten Wandteile 11, 12 unter einer gewünschten Vorspannkraft in Anlage miteinander stehen.A passage opening 14 is provided in the membrane-like wall part 11 of the first closing element 7 facing the dispensing opening 4. One or more passage openings 15 in the membrane-like wall part 12 of the second closing element 8 create a connection between the top and bottom of the membrane-like wall part 12 at a point which is radially offset from a central region of the wall part 12. The central area of the wall part 12 is therefore free of Perforations and thus suitable to seal the central passage opening 14 of the first closing element 7 in the rest position shown in FIG. 1 when the domes of the curved wall parts 11, 12 are in contact with one another under a desired pretensioning force.
Die Schliesselemente 7, 8 können aus einem geeigneten elastischen Kunststoffmaterial gefertigt sein, das sich durch Spritzformen in die gewünschte Konfiguration fertigungsgünstig bringen lässt . Geeignete Materialien sind insbesondere elastomere Materialien. Die Schliesselemente 7, 8 können aus gleichem oder unterschiedlichem Material bestehen, um gleiche oder unterschiedliche elastische Eigenschaften zu erhalten.The closing elements 7, 8 can be made of a suitable elastic plastic material, which can be brought into the desired configuration in an inexpensive manner by injection molding. Suitable materials are in particular elastomeric materials. The closing elements 7, 8 can consist of the same or different material in order to obtain the same or different elastic properties.
Die Funktion der, wie vorbeschrieben, aufgebauten selbstschliessenden Ventilanordnung wird nachfolgend anhand von Fig. 2 und 3 erläutert. Fig. 2 zeigt den Zustand der Ventilanordnung, wie er vorliegt, wenn auf das erste Schliesselement 7 eine Differenzdruckkraft von unten ausgeübt wird, die bewirkt, dass sich der Wandteil 11 vom Wandteil 12 des zweiten Schliesselements 8 abhebt, und die Durchtrittsoffnung 14 dadurch freigegeben wird. Dieser Zustand kann dadurch hervorgerufen werden, dass durch Zusammendrücken der Wand eines Behälters darin ein Überdruck hervorgerufen wird. Sobald der Überdruck wegfällt, kehrt der Wandteil 11 des ersten Schliesselements 7 aufgrund seiner Elastizität wieder in die in Fig. 1 gezeigte Ausgangsposition unter Abdichtung der Druchtrittsö fnung 14 zurück. Bei einem Überdruck im Behälter erfährt der Wandteil 12 des zweiten Schliesselements 8 dagegen im wesentlichen keine Formänderung, da der Überdruck die gewölbte Konfiguration des Wandteils 12 unterstützt. Die Rückstellung der Behälterwand nach Wegnahme der Quetschkraft kann einen Unterdruck im Behälter hervorrufen, der eine vollständige Rückstellung in die ursprüngliche Konfiguration verhindern würde, wenn kein Druckausgleich zwischen dem Behälterinneren und der Umgebung stattfinden könnte. Die Stellung, die die Teile der Ventilanordnung 1 zum Druckausgleich einnehmen, ist in Fig. 3 gezeigt. Bei Unterdruck im Behälter wirkt auf den Wandteil 12 des zweiten Schliesselements 8 eine Differenzdruckkraft, die eine Verformung des Wandteils 12 weg von der Durchtrittsoffnung 14 des ersten Schliesselements 7 zur Folge hat, so dass die Durchtrittsoffnung 14 erneut freigegeben wird. Infolge davon kann Luft aus der Aussenumgebung durch die Durchtrittsöffnungen 14 und 15 der Wandteile 11, 12 der Schliesselemente 7, 8 ins Behälterinnere strömen, bis ein Druckausgleich erfolgt ist und dadurch der Wandteil 12 wieder entlastet wird und aufgrund der elastischen Eigenschaft des Materials in die in Fig. 1 gezeigte Ausgangsposition unter Verschliessen der Durchtrittsoffnung 14 zurückfedern kann.The function of the self-closing valve arrangement constructed as described above is explained below with reference to FIGS. 2 and 3. Fig. 2 shows the state of the valve arrangement as it is when a differential pressure force is exerted on the first closing element 7 from below, which causes the wall part 11 to lift off the wall part 12 of the second closing element 8 and the passage opening 14 is thereby released . This condition can be caused by the fact that compressing the wall of a container causes an overpressure therein. As soon as the excess pressure disappears, the wall part 11 of the first closing element 7 returns due to its elasticity into the starting position shown in FIG. In the event of an overpressure in the container, however, the wall part 12 of the second closing element 8 experiences essentially no change in shape, since the overpressure supports the arched configuration of the wall part 12. Resetting the container wall after the squeezing force is removed can create a negative pressure in the container which would prevent a complete return to the original configuration if there was no pressure equalization between the container interior and the surroundings. The position which the parts of the valve arrangement 1 assume for pressure equalization is shown in FIG. 3. In the event of negative pressure in the container, a differential pressure force acts on the wall part 12 of the second closing element 8, which causes the wall part 12 to deform away from the passage opening 14 of the first closing element 7, so that the passage opening 14 is released again. As a result, air from the outside environment can flow through the through openings 14 and 15 of the wall parts 11, 12 of the closing elements 7, 8 into the interior of the container until pressure equalization has taken place and the wall part 12 is relieved again and, due to the elastic property of the material, into the interior of the container Fig. 1 shown spring back by closing the passage opening 14 can spring back.
Die Erfindung wurde vorausgehend anhand einer Ausführungsform mit gewölbten membranartigen Wandteilen der Schliesselemente beschrieben. Die Erfindung ist hierauf jedoch nicht beschränkt . Insbesondere kann anstelle eines gewölbten Wandteils des zweiten Schliesselements auch ein unter den einwirkenden Kräften axial bewegliches zentrales Dichtungselement zum Abdichten der Durchtrittsoffnung im ersten Schliesselement vorgesehen sein. Dieses Dichtungselement kann z.B. durch speichenartige Streben mit dem äusseren verdickten Montagebereich des zweiten Schliesselements verbunden sein. Der Stützring, auf den sich die übereinander angeordneten Schliesselemente abstützen, ist nicht obligatorisch und kann daher, wenn erwünscht, weggelassen werden. In diesem Fall würde sich der verdickte Montagebereich des zweiten Schliesselemente direkt auf einem Ringbund oder einem ähnlichen Teil des Behälters abstützen können. The invention has been described above with reference to an embodiment with curved membrane-like wall parts of the closing elements. However, the invention is not limited to this. In particular, instead of a curved wall part of the second closing element, a central sealing element which is axially movable under the acting forces can also be provided for sealing the passage opening in the first closing element. This sealing element can be connected to the outer thickened mounting area of the second closing element, for example by spoke-like struts. The support ring on which the closing elements arranged one above the other are supported is not mandatory and can, if desired, be omitted. In this case, the thickened Can support the mounting area of the second closing element directly on a collar or a similar part of the container.
