Abstract

Closures are known, which only permit the contents of the container to be squeezed out in an unsatisfactory manner and are furthermore of relatively complex design and therefore expensive to manufacture. The object of the invention, in addition to cost-effective manufacture, is also to permit the contents to be squeezed out of the container in an optimum manner. For this purpose, provision is made for the lid part (5) to consist of a material of high elasticity and to be firmly connected to a supporting body (4) which is formed from a material of less elasticity and is otherwise joined to the neck of the bottle (1) or to the closure (2). <IMAGE>

Description

Die vorliegende Erfindung betrifft einen Behälter für flüssigen oder pastenförmigen Inhalt gemäß dem Oberbegriff des Anspruches 1.The present invention relates to a container for liquid or pasty Content according to the preamble of claim 1.

Ein derartiger Verschluß ist aus der DE-A-35 31 783 bekannt.Such a closure is known from DE-A-35 31 783.

Darin sind zum selbsttätigen Rückstellen, d.h. Schließen der Klappen Blattfedern oder ein elastischer Ring vorgesehen. Letzterer umschließt den Verschluß im unteren Schlitzbereich der Klappen. Zur Funktionsfähigkeit dieses elastischen Ringes ist jedoch eine etwa zylindrische Ausbildung des Verschlusses notwendig, so daß zumindest in gestalterischer Hinsicht die Verwendung dieses Verschlusses eingeschränkt ist.In it are for automatic resetting, i.e. Closing the leaf springs flaps or an elastic ring is provided. The latter encloses the closure in the lower one Slit area of the flaps. The functionality of this elastic ring is however, an approximately cylindrical design of the closure is necessary so that at least in terms of design, the use of this closure is restricted is.

Aufgrund der gegebenen Hebelverhältnisse ist ein zuverlässiges Schließen der Klappen durch diesen elastischen Ring nicht gewährleistet. Die alternativ dazu vorgesehenen Blattfederelemente sind insbesondere in fertigungstechnischer Hinsicht nur mit einem erheblichen aufwand einzubringen, wobei zu berücksichtigen ist, daß solche Behälter als Massenartikel hergestellt werden und insofern äußerst kostengünstig kalkuliert werden müssen.Due to the given leverage conditions, the flaps must be closed reliably not guaranteed by this elastic ring. The alternatively provided Leaf spring elements are only included, particularly in terms of production technology to bring considerable effort, taking into account that such Containers are mass-produced and therefore extremely inexpensive have to be calculated.

Weiter ist ein Behälter aus der DE-A-26 09 310 bekannt, bei dem die Rückstellung der Klappen in eine Schließstellung durch die Wahl eines Elastizitätskräfte aufweisenden Werkstoffes erreicht werden soll. Furthermore, a container is known from DE-A-26 09 310, in which the provision the flaps in a closed position by choosing an elasticity Material should be achieved.

Allerdings hat sich gezeigt, daß auch hier keine zuverlässige Rückstellung erfolgt, insbesondere wenn Reste des ausgetretenen Behälterinhalts die Schließfuge verkleben.However, it has been shown that there is no reliable reset here either, especially if residues of the leaked container contents stick to the closing joint.

Der vorliegenden Erfindung liegt daher die Aufgabe zugrunde, einen Behälter der gattungsgemäßen Art so zu gestalten, daß die Klappen in jedem Fall zuverlässig selbsttätig schließen und daß der Verschluß insgesamte einfach und wirtschaftlich herstellbar ist.The present invention is therefore based on the object of a container Generic type so that the flaps are reliable in any case close automatically and that the closure overall simple and economical can be produced.

Diese Aufgabe wird durch einen Behälter gelöst, der die Merkmale des Anspruches 1 aufweist.This object is achieved by a container which has the features of claim 1 having.

Hierdurch wird eine gute Halterung der gegenständigen Klappen im geschlossenen Zustand gesichert und damit auch ein guter Verschluß des Behälterinhalts. Anderseits ist das balkenförmige Auflager nur verhältnismäßig schmal. Es bewirkt zwar eine Teilung des ausgedrückten Stranges an der Stelle, an der es angeordnet ist, diese Teilung des ausgedrückten Strangs wird jedoch sogleich wieder rückgängig gemacht aufgrund der schrägen Anstellung der beiden gegenständigen Klappen, die den ausgedrückten Strang oberhalb dieses balkenförmigen Auflagers wieder zusammendrücken, so daß ein einheitlicher kompakter Strang zwischen den beiden geöffneten Begrenzungen der Klappen austritt.As a result, the opposite flaps are held well in the closed position Condition secured and thus also a good closure of the container contents. On the other hand the beam-shaped support is only relatively narrow. It does division of the expressed strand at the point at which it is arranged, however, this division of the expressed strand is immediately reversed made due to the inclined position of the two opposite flaps, the the expressed strand above this beam-shaped support again squeeze so that a uniform compact strand between the two open limits of the flaps emerges.

Eine zum Innern des Behälters gerichtete schneidenförmige Ausbildung des balkenförmigen Auflagers wirkt dabei strömungsgünstig auf den Strang während des Ausdrückvorganges, so daß eine gleichmäßige Verteilung des ausgedrückten Stranges nach beiden Seiten hin erfolgt und damit keine der beiden gegenständig angeordneten Klappen beim Ausdrückvorgang weiter geöffnet wird, was ein Abweichen des ausgedrückten Stranges von einer geraden Ausdrucksrichtung zur Folge hätte.A blade-shaped configuration of the bar-shaped, directed towards the inside of the container The support has a streamlined effect on the strand during the squeezing process, so that an even distribution of the expressed strand takes place on both sides and thus neither of the two oppositely arranged Folding is further opened during the squeezing process, which is a deviation of the expressed strand from a straight direction of expression.

Vorteilhaft sind unter den Klappen in den Behälterhals hineinreichende Arme angeordnet, deren freie Enden mit einer Feder verbunden sind, die ihrerseits am Behälterhals festsitzt. Zweckmäßig sind diese Arme unter den beiden Seiten der Klappen mit Verbreiterungen versehen.Arms extending into the neck of the container are advantageously arranged under the flaps, whose free ends are connected to a spring, which in turn on the neck of the container stuck. These arms are conveniently located under the two sides of the flaps provided with extensions.

Durch diese Anordnung wird eine exakte Führung der Klappen beim Öffnungs- und Schließvorgang gegen die Wirkung der Schließfeder erreicht, so daß in jeder Öffnungsstellung und insbesondere in der Schließstellung die Schließfeder optimal mit den Klappen gleichmäßig zusammenwirkt. Weiterhin wird durch die Verbreiterung der an den beiden Seiten der Klappen angeordneten Arme wirksam verhindert, daß beim Öffnen der Klappen von dem Behälterinhalt Teile die Klappen seitlich umströmen - es wird praktisch ausschließlich nur der praktisch in den beiden Klappen sich öffnende Schlitz, schmaler oder breiter, zur Formung des aus dem Verschluß austretenden Stranges benutzt.With this arrangement, the flaps are guided precisely when opening and closing Closing operation against the action of the closing spring is achieved, so that in every open position and especially in the closed position, the closing spring with the flaps cooperate evenly. Furthermore, the widening of Arms arranged on both sides of the flaps effectively prevents the Parts of the flaps flow around the side of the container - es practically only the one that practically opens in the two flaps Slit, narrower or wider, to shape what emerges from the closure Stranges used.

Weitere Merkmale und Vorteile ergeben sich aus der nachstehenden Beschreibung eines Ausführungsbeispiels anhand der beiliegenden Zeichnungen. In den Zeichnungen zeigen:

Auf den Hals 51 des Behälters 52 ist ein Deckel aufgesetzt, der mit einem nach außen stehenden ringförmigen Flansch 54 auf der Oberkante des Halses 51 aufsitzt, ggf. mit einer Zwischenlage in Form einer Dichtung. Der Deckel 53 wird festgehalten von einer Überwurfkappe 55, die mit einem Schraubgewinde 56 auf das außen an dem Hals 51 angeordnete Gewinde aufgeschraubt ist, wobei die Überwurfkappe 55 mit einem nach innen ragenden kreisförmigen Vorsprung 57 versehen ist, der den Flansch 54 übergreift. Durch Aufschrauben der Überwurfkappe 55 kann also der Deckel 53 fest dichtend und sicher auf den Hals 51 des Behälters 52 aufgebracht werden.On the neck 51 of the container 52, a lid is placed, with one after external annular flange 54 is seated on the upper edge of the neck 51, if necessary with an intermediate layer in the form of a seal. The lid 53 is held from a cap 55 with a screw thread 56 on the outside the thread arranged on the neck 51 is screwed on, the cap 55 is provided with an inwardly projecting circular projection 57 which the Flange 54 overlaps. By screwing on the cap 55 so Lid 53 tightly and securely applied to the neck 51 of the container 52 will.

Diese gesamte Anordnung anstelle eines üblichen, den Behälter verschließenden Schraubdeckels und gegen diesen Schraubdeckel ausgetauscht werden, so daß jeder Behälter mit Normschraubdeckel mit diesem Verschluß versehen werden kann.This entire arrangement instead of a conventional one that seals the container Screw cap and be replaced with this screw cap, so that Every container with a standard screw cap can be fitted with this closure.

Der mittlere Bereich des Deckels 53 ist mit einer beispielsweise rechteckig begrenzten Öffnung 58 versehen, an deren Außenrändern Klappen 59 mit Scharnieren 60 angelenkt sind. Die Klappen 59 sind gegenständig, so daß sie beim Öffnen zwischen ihren gegeneinanderliegenden Kanten 61 einen Öffnungsschlitz freigeben, durch den der Behälterinhalt austreten kann. Die Öffnung 58 ist in ihrer Mitte mit einem balkenförmigen Auflager 62 versehen, auf dem die gegeneinanderstehenden Außenkanten 61 der Klappen 59 in geschlossenem Zustand dichtend aufliegen. Dazu können diese Außenkanten 61 derart ausgebildet sein, daß sie mit einem Winkelprofil 63 das balkenförmige Auflager 62 in geschlossenem Zustand auf der Oberseite und an den beiden Seitenflächen überdecken.The central area of the cover 53 is, for example, rectangularly delimited Provide opening 58, on the outer edges of flaps 59 with hinges 60th are articulated. The flaps 59 are opposite, so that they open between their opposing edges 61 release an opening slot through which the contents of the container can leak out. The opening 58 is in the middle with a bar-shaped Support 62 provided on which the opposing outer edges 61 of the flaps 59 rest sealingly in the closed state. You can do this Outer edges 61 may be formed such that they have the bar-shaped with an angle profile 63 Support 62 in the closed state on the top and on the cover both sides.

Die Gesamtanordnung ist vorzugsweise derart ausgebildet, daß sämtliche der vorbeschriebenen Einzelteile aus Kunststoff bestehen und zusammenhängend in einer Form gespritzt sind, wobei die Scharniere 60 als Filmascharniere ausgebildet sind.The overall arrangement is preferably designed such that all of the above Individual parts made of plastic and connected in one Mold injected, the hinges 60 are designed as film hinges.

Nahe der beiden Seitenkanten der Klappen 59 sind in den Behälterhals 51 hineinragende Arme angeformt und zwar zweckmäßig einstückig und aus gleichem Material bestehend wie die Klappen 59, wobei dieses Material aufgrund der Querschnittsausbildung der Arme 64 biegsam bzw. federelastisch ist. In ihrem oberen Teil sind die Arme 64 mit Verbreiterungen 65 versehen, die unter den beiden Seiten der Klappen 59 nach unten ragen und gegen die Seiten der Öffnungen 59 in dem Deckel 53 anlegen, so daß bei aufschwenkenden Klappen 59 der Behälterinhalt nicht nach den Seiten hin austreten kann, sondern zur Mitte hin ausschließlich sich durch den zwischen den beiden Klappen 59 bildenden Schlitz gelenkt wird. An ihrem unteren Ende sind die Arme 64 der Klappen 59 miteinander durch einen Quersteg verbunden.Near the two side edges of the flaps 59 protrude into the container neck 51 Molded arms and expediently in one piece and from the same material consisting of the flaps 59, this material due to the cross-sectional formation the arm 64 is flexible or resilient. In their upper part they are Arms 64 provided with extensions 65, which are under the two sides of the flaps 59 protrude downward and against the sides of the openings 59 in the cover 53 put on, so that when the flaps 59 open, the container content is not after Can emerge towards the sides, but towards the center only through the between the two flaps 59 forming slot is directed. At its bottom the arms 64 of the flaps 59 are connected to one another by a crosspiece.

Eine Blattfeder 67 ist unterhalb des Deckels 53 angeordnet. Die Blattfeder 67 ist mit ihren freien Enden 68 in einem ringförmigen Teil 69 verankert, der zwischen den Flanschen 54 an dem Deckel und der Begrenzung der Öffnung 58 in dem Deckel 53, diesen auf seiner ebenen Seite umgibt. Die Blattfeder 67 ist geformt wie ein großes W mit langen hochstehenden Außenschenkeln 70 und einem inneren kurzen Winkel 67, der im Scheitel 62 mit den beiden Armen 64 verbunden ist, und zwar in der Weise, daß er den die Arme 64 verbundenden Stab 66 übergreift.A leaf spring 67 is arranged below the cover 53. The leaf spring 67 is with their free ends 68 anchored in an annular part 69 which is between the Flanges 54 on the cover and the delimitation of the opening 58 in the cover 53, surrounds it on its flat side. The leaf spring 67 is shaped like a large one W with long upstanding outer legs 70 and an inner short angle 67, which is connected in the apex 62 to the two arms 64, namely in the Way that it engages over the rod 66 connecting the arms 64.

Bei der Darstellung in Fig. 1 ist die W-förmige Feder in weitgehend entspanntem Zustand. Auch die Arme 64 befinden sich in ihrem Normalzustand und die Klappen 59 des Verschlusses sind geschlossen. Die W-förmige Feder 67 hat jedoch noch eine Vorspannung, so daß sie insbesondere in ihrem mittleren Bereich mit dem hochstehenden inneren Winkel 72 auf die Verbindung 66 zwischen den beiden Armen 64 wirkt, diese nach unten zieht und damit die Klappen 59 in Schließstellung hält.In the illustration in Fig. 1, the W-shaped spring is largely relaxed Status. The arms 64 are also in their normal state and the flaps 59 of the closure are closed. However, the W-shaped spring 67 still has a bias, so that it is in particular in its central area with the upstanding inner angle 72 on the connection 66 between the two Arms 64 acts, this pulls down and thus the flaps 59 in the closed position holds.

Die Kraft der Feder 67 ist derart abgestimmt, daß bei einem nicht zu starken Druck auf den Behälterinhalt, also bei einem Zusammendrücken des Behälters, der dann im Behälterinnern wirkende Druck auf die Klappen 59 öffnend wirkt, indem die Rückstellkraft der Feder 67 überwunden wird. The force of the spring 67 is adjusted so that when the pressure is not too high on the contents of the container, i.e. when the container is compressed, which is then in the Pressure acting inside the container on the flaps 59 acts by the restoring force the spring 67 is overcome.

Die Klappen 59 öffnen sich und es stellt sich die Stellung entsprechend der Fig. 2 ein, in der zwischen den beiden Klappen 59 ein Öffnungsschlitz entsteht, aus dem der Behälterinhalt in einem kompakten, im wesentlichen rechteckig begrenzten Strang austritt. Abhängig von dem Druck, der auf den Behälter ausgeübt wird, wird die Rückstellkraft der Feder 67 mehr oder weniger stark überwunden, so daß sich die Klappen 59 mehr oder weniger weit öffnen und dem entsprechend dem zwischen ihnen entstehenden Schlitz größer oder kleiner ist. In dieser Weise läßt sich durch entsprechenden Druck auf den Behälter der austretende Behälterinhalt bzw. die Stärke des aus dem Behälter durch den Schlitz zwischen den Klappen 59 austretenden Inhaltes sehr genau dosieren.The flaps 59 open and the position shown in FIG. 2 is set, in which an opening slot is created between the two flaps 59, from which the Container contents in a compact, essentially rectangular strand exit. Depending on the pressure applied to the container, the Resetting force of the spring 67 more or less overcome, so that the Open flaps 59 to a greater or lesser extent and accordingly between resulting slot is larger or smaller. In this way you can appropriate pressure on the container of the emerging container content or Strength of the emerging from the container through the slot between the flaps 59 Dispense content very precisely.

Wird kein Druck mehr auf den Behälter 52 ausgeübt, schließen sich die Klappen 59 unter der Wirkung der Rückstellkraft der Feder 67. Der aus dem Behälter ausgetretene kompakte Strang des Behälterinhalts wird durch die sich schließenden Klappen sauber abgetrennt und die Klappen drücken einen letzten verbleibenden Rest des ausgetretenen Behälterinhalts wieder in den Behälter zurück aufgrund ihrer Schließbewegung gegenüber dem balkenförmigen Auflager 62 und aufgrund ihrer besonderen Ausformung mit dem nach innen eingenommenen Winkelprofil 63, das mit seinem senkrechten Schenkel gegenüber dem balkenförmigen Auflager 62 eine Abstreifbewegung nach unten erzeugt.When pressure is no longer applied to the container 52, the flaps 59 close under the action of the restoring force of the spring 67. The one emerging from the container compact strand of the container contents is due to the closing flaps neatly separated and the flaps press a last remaining remainder of the leaked container contents back into the container due to their closing movement compared to the beam-shaped support 62 and because of their special Formation with the inwardly taken angle profile 63, which with its vertical leg opposite the beam-shaped support 62 a Downward wiping movement generated.

Zum sicheren Verschließen, beispielsweise bei längerem Nichtgebrauch oder Transport, kann eine zusätzliche Sicherung verwendet werden, und zwar eine Überwurfkappe, die hier nicht dargestellt ist, die sich mit einem mittleren Teil flach auf die beiden Kappen 59 von außen und oben auflegt und mit einem nach unten stehenden Rand an der Klappe 55 fest angeklipst oder auf diese fest aufgeschraubt wird. Es ist auch möglich, anstelle dieser zusätzlichen Überwurfkappe eine Verschlußkappe zu verwenden, die ähnlich ausgebildet ist wie die Kappe 55 und gegen diese ausgestauscht wird, wobei hier ebenfalls eine nicht dargestellte Verschlußkappe zwischen den nach nach innen ragenden Vorsprüngen 57 einstückig fortgeführt ist, so daß dieser mittlere Teil sich auf die Außenseiten der beiden Klappen 59 beim Aufschrauben auf das Gewinde 56 fest dichtend und verschließend auflegt.For secure locking, for example when not in use for a long time or during transport, an additional fuse can be used, namely a cap, which is not shown here, with a central part flat on the two Place caps 59 from the outside and above and with one standing down Edge is firmly clipped onto the flap 55 or screwed onto it. It is also possible, instead of this additional cap to a cap use, which is similar to the cap 55 and replaced with this is, here also a closure cap, not shown, between the inwardly projecting projections 57 is continued in one piece, so that this middle part on the outside of the two flaps 59 at Screw on the thread 56 tightly sealing and closes.

Der Verschluß ist insbesondere hinsichtlich der Anordnung der Feder derart ausgebildet, daß er eine zusammenhängende Einheit bildet.The closure is designed in particular with regard to the arrangement of the spring in such a way that it forms a coherent unit.
