Description

Die Erfindung betrifft einen Behälter für fließfähige Medien, insbesondere einen im Wege der Blasformgebung geformten Behälter aus Kunststoff, - mit einer in bezug auf das fließfähige Medium geschlossenen Belüftungseinrichtung in einer runden Kragenöffnung der Behälterdecke. Bei dem fließfähigen Medium kann es sich um eine Flüssigkeit mit hoher oder niedriger Viskosität handeln, es kann sich aber auch um ein fließfähiges feinkörniges oder pulverförmiges Medium handeln. Belüftungseinrichtung meint eine Einrichtung, die einen Druckaufbau in dem Behälter ebenso verhindert wie die Entstehung eines Unterdrucks. Ein Drukkaufbau oder ein Unterdruck können beispielsweise entstehen, weil das in den Behälter eingefüllte fließfähige Medium sich unter dem Einfluß der Temperatur volumenmäßig verändert, also gleichsam "atmet". Behälter mit einer derartigen Belüftungseinrichtung werden auch für Klebstoffe eingesetzt.The invention relates to a container for flowable media, in particular a blow molded plastic container, - with a closed with respect to the flowable medium ventilation device in a round collar opening of the container ceiling. The flowable medium can be a liquid with a high or low viscosity, but it can also be a flowable fine-grained or powdery medium. Aeration device means a device that prevents pressure build-up in the container as well as the creation of a negative pressure. A pressure purchase structure or a vacuum can arise, for example, because the flowable medium filled into the container changes in volume under the influence of the temperature, that is to say "breathes". Containers with such a ventilation device are also used for adhesives.

Es sind Behälter des vorstehend beschriebenen grundsätzlichen Aufbaus bekannt, die im unteren Bereich einer Seitenfläche eine Entnahmeöffnung und in der Deckfläche eine Belüftungseinrichtung aufweisen. Im einfachsten Fall besteht eine solche Belüftungseinrichtung aus einer Bohrung geringen Durchmessers in einem Deckel, der auf den Kragen einer entsprechenden Öffnung aufgeschraubt ist. Dabei kann nicht verhindert werden, daß beim "Atmen" des Behälterinhaltes Schadstoffe oder Wasser in den Behälterinnenraum eindringen.Containers of the basic structure described above are known which have a removal opening in the lower region of a side surface and a ventilation device in the top surface. In the simplest case, such a ventilation device consists of a small diameter bore in a cover which is screwed onto the collar of a corresponding opening. It cannot be prevented that pollutants or water penetrate into the interior of the container when the container is "breathing".

Der Erfindung liegt die Aufgabe zugrunde, einen aus Kunststoff bestehenden Behälter für fließfähige Medien zu schaffen, der mit einer Belüftungseinrichtung versehen ist, die gleichzeitig sicherstellt, daß mit der Luft feinteilige Schadstoffe oder Wasser in den Behälter nicht eindringen können.The invention has for its object to provide a plastic container for flowable media, which is provided with a ventilation device, which at the same time ensures that finely divided pollutants or water can not penetrate into the container.

Zur Lösung dieser Aufgabe ist Gegenstand der Erfindung ein Behälter für fließfähige Medien, insbes. im Wege der Blasformgebung geformte Behälter aus Kunststoff, mit einer in bezug auf das fließfähige Medium geschlossenen Belüftungseinrichtung in einer runden Kragenöffnung der Behälterdecke, mitTo achieve this object, the subject of the invention is a container for flowable media, in particular by plastic blow molding, with a ventilation device closed with respect to the flowable medium in a round collar opening of the container top with

wobei der zylindrische Zentralkörper, die Schutzkappe und der Flachdeckel miteinander vereinigt sind und der Flachdeckel mit Hilfe einer Öffnungsschutzeinrichtung, die beim Öffnen des Flachdekkels bricht, befestigt ist. Dabei können der zylindrische Zentralkörper, die Schutzkappe und der Flachdeckel aus Kunststoff geformt sein. Die Vereinigung kann stoffschlüssig oder formschlüssig, z.B. durch Schweißen oder Verrasten, erfolgen. Der Boden weist zumindest eine Filteröffnung auf. Der Durchlaß kann eine Ausnehmung oder eine Bohrung sein.a flat cover which, with collar elements, encompasses and is united with the ring flange of the central body and has slot spaces for ventilation in the region between the collar elements,
wherein the cylindrical central body, the protective cap and the flat cover are combined with one another and the flat cover is fastened with the aid of an opening protection device which breaks when the flat cover is opened. The cylindrical central body, the protective cap and the flat cover can be molded from plastic. The union can take place cohesively or positively, for example by welding or locking. The bottom has at least one filter opening. The passage can be a recess or a bore.

Die Erfindung geht von der Erkenntnis aus, daß bei einer Belüftungseinrichtung, die aus den beschriebenen Bauteilen Zentralkörper, Schutzkappe und Flachdeckel aufgebaut ist, einerseits ein Raum entsteht, in dem Filterstoffe untergebracht werden können, beispielsweise auch in Form einer Patrone eingesetzt werden können, was das Eindringen von feinteiligen Verunreinigungen in den Behälterinnenraum beim "Atmen" des eingefüllten fließfähigen Mediums verhindert. Der Flachdeckel schützt die Belüftungseinrichtung insgesamt und funktioniert gleichzeitig als eine Sicherheitsvorrichtung gegen unkontrolliertes Öffnen.The invention is based on the finding that, in the case of a ventilation device which is constructed from the described central body, protective cap and flat cover, on the one hand a space is created in which filter materials can be accommodated, for example in the form of a cartridge, which can be used Prevention of fine-particle contamination into the interior of the container when the filled flowable medium "breathes" is prevented. The flat lid protects the ventilation device as a whole and at the same time functions as a safety device against uncontrolled opening.

Im einzelnen bestehen im Rahmen der Erfindung mehrere Möglichkeiten der weiteren Ausbildung und Gestaltung. So kann der ebene Flachdeckel oberseitig Vertiefungen zum Einsetzen eines Betätigungswerkzeuges aufweisen.There are several options for further training and design within the scope of the invention. For example, the flat flat cover can have depressions on the upper side for inserting an actuating tool.

Bei einem erfindungsgemäßen Behälter kann die Belüftungseinrichtung unschwer so gestaltet werden, daß im Innern des Behälters ein geringfügiger und kontrollierter Druckaufbau bzw. ein geringfügiger und kontrollierter Unterdruck sich einstellen. Dazu empfiehlt die Erfindung, daß der Boden des Zentralkörpers Öffnungen aufweist, auf die ein Strömungswiderstandsvlies aufgesetzt ist. Es kann aber auch der Zentralkörper oben von einem solchen Strömungswiderstandsvlies abgedeckt sein.In the case of a container according to the invention, the ventilation device can easily be designed such that a slight and controlled pressure build-up or a slight and controlled negative pressure occur in the interior of the container. For this purpose, the invention recommends that the bottom of the central body has openings on which a flow resistance fleece is placed. However, the top of the central body can also be covered by such a flow resistance fleece.

Bei einem erfindungsgemäßen Behälter erfüllt die Belüftungseinrichtung die angegebene Funktion. Besitzt der Behälter eine untere Entleeröffnung mit einem Verschlußkörper, z. B. in Form eines Hahns, so kann die Belüftungseinrichtung für eine Luftzufuhr beim Auslaufen des Mediums über die Entleeröffnung eingerichtet sein. Es empfiehlt sich in diesem Fall, die beschriebenen Öffnungen mit ausreichend großem Durchmesser zu versehen und die Filtersubstanz in dem Zentralkörper fortzulassen bzw. zu entfernen.In a container according to the invention, the ventilation device fulfills the stated function. The container has a lower emptying opening with a closure body, e.g. B. in the form of a tap, the ventilation device can be set up for an air supply when the medium runs out through the discharge opening. In this case it is advisable to provide the openings described with a sufficiently large diameter and to remove or remove the filter substance in the central body.

Der in den Figuren dargestellte Behälter 1 ist für fließfähige Medien bestimmt und besteht aus Kunststoff. Er ist vorzugsweise im Wege der Blasformgebung geformt. Er ist mit einer in bezug auf das fließfähige Medium geschlossenen Belüftungseinrichtung 2 versehen, die unmittelbar oder mit Hilfe eines Schraubendeckels in einer runden Kragenöffnung 3 des Behälters 1 untergebracht ist. Zunächst wird auf die Fig. 2 und 3 verwiesen. Man erkennt einen zylindrischen Zentralkörper 4, der in die Kragenöffnung 3 eingesetzt ist, einen Boden 5 mit zumindest einer Filteröffnung 6 aufweist und unter Zwischenschaltung eines Dichtungsringes 7 mit einem angeformten Ringflansch 8 auf den Kragen 9 der Kragenöffnung 3 aufgesetzt ist. In dem Zentralkörper 4 ist eine Filtersubstanz 10, beispielsweise in Form einer Filterpatrone, untergebracht. Unter dem Zentralkörper 4 befindet sich, zum Behälterinnenraum hin konvex, eine kugelkalottenförmige oder kegelförmige Schutzkappe 11. Im Ausführungsbeispiel ist sie kegelförmig ausgeführt. Sie ist am Boden 5 des Zentralkörpers 4 befestigt. Zumindest in ihrem tiefsten Punkt besitzt diese Schutzkappe 11 als Durchlaß 12 eine Bohrung. Außerdem ist ein ebener Flachdeckel 13 vorgesehen, der mit Bundelementen 14 den Ringflansch 8 des Zentralkörpers 4 umfaßt und im Bereich zwischen den Bundelementen 14 Schlitzräume 15 für die Belüftung aufweist.The container 1 shown in the figures is intended for flowable media and consists of plastic. It is preferably shaped by blow molding. It is provided with a ventilation device 2 which is closed with respect to the flowable medium and which is accommodated directly or with the aid of a screw cap in a round collar opening 3 of the container 1. First, reference is made to FIGS. 2 and 3. A cylindrical central body 4 can be seen, which is inserted into the collar opening 3, has a bottom 5 with at least one filter opening 6 and is placed on the collar 9 of the collar opening 3 with the interposition of a sealing ring 7 with an integrally formed ring flange 8. A filter substance 10, for example in the form of a filter cartridge, is accommodated in the central body 4. Under the central body 4 there is a spherical cap or conical protective cap 11, convex towards the interior of the container. In the exemplary embodiment, it is designed conical. It is attached to the bottom 5 of the central body 4. At least at its lowest point, this protective cap 11 has a bore as a passage 12. In addition, a flat flat cover 13 is provided which, with collar elements 14, encompasses the ring flange 8 of the central body 4 and in the region between the collar elements 14 has slot spaces 15 for ventilation.

Der zylindrische Zentralkörper 4, die Schutzkappe 11 und der Flachdeckel 13 sind durch Schweißen miteinander vereinigt. Der Flachdeckel 13 ist mit Hilfe von Öffnungsschutzelementen 16, die beim Öffnen des Flachdeckels 13 brechen, an dem Kragen 9 der Kragenöffnung 3 befestigt. Der zylindrische Zentralkörper 4, die Schutzkappe 11 und der Flachdeckel 13 bestehen aus Kunststoff. Der Flachdeckel 13 besitzt oberseitig Vertiefungen 17 zum Einsetzen eines Werkzeuges. Angedeutet wurde in der Fig. 2 rechts, daß man die Filtersubstanz weglassen und auf den Zentralkörper 4 eine Abdeckung 18 aufsetzen kann. Entsprechend könnte man auf den Zentralkörper 4 ein Strömungswiderstandsvlies aufsetzen. Ein Strömungswiderstandsvlies könnte aber auch auf die Filteröffnung 6 aufgesetzt sein. Auf diese Weise kann erreicht werden, daß ein zulässiger Innendruck im Behälter sich aufbaut oder ein zulässiger Unterdruck sich einstellt. Vergrößert man die beschriebenen Öffnungen und läßt man die Filtersubstanz weg, so kann die Belüftungseinrichtung 2 auch für die Luftzufuhr bei einem Auslaufen des Mediums aus dem Behälter 1 über eine untere Entleeröffnung 19 funktionieren.The cylindrical central body 4, the protective cap 11 and the flat cover 13 are joined together by welding. The flat cover 13 is fastened to the collar 9 of the collar opening 3 by means of opening protection elements 16 which break when the flat cover 13 is opened. The cylindrical central body 4, the protective cap 11 and the flat cover 13 are made of plastic. The flat cover 13 has recesses 17 on the upper side for inserting a tool. It was indicated in FIG. 2 on the right that the filter substance can be omitted and a cover 18 can be placed on the central body 4. Correspondingly, a flow resistance fleece could be placed on the central body 4. A flow resistance fleece could also be placed on the filter opening 6. In this way it can be achieved that a permissible internal pressure builds up in the container or that a permissible negative pressure is established. If the openings described are enlarged and the filter substance is left out, the ventilation device 2 can also function for the air supply when the medium runs out of the container 1 via a lower emptying opening 19.

Bei der Ausführungsform nach den Fig. 4 und 5 ist die Belüftungseinrichtung in einen Schraubdeckel 21 eingesetzt, der auf den Kragen der Kragenöffnung aufgeschraubt ist. Die Öffnungsschutzeinrichtung 16 ist eine aus Blech oder Folie geformte Kappe, die an dem Flachdeckel 13 befestigt ist. In die Fig. 4 und 5 sind die bereits erläuterten Bezugszeichen eingetragen worden, weil die Ausführungsform nach den Fig. 4 und 5 insoweit mit der Ausführungsform nach den Fig. 2 und 3 übereinstimmt. Als Durchlaß 12 sind besondere Ausnehmungen vorgesehen. Die Anordnung ist jedoch im übrigen in den Fig. 4 und 5 so getroffen, daß der Zentralkörper 4 zum Behälterinnenraum hin über den Boden 5 vorsteht, so daß der Zentralkörper 4 eine obere Zentralkörperkammer 4a aufweist, in der die Filtersubstanz 10 angeordnet ist, sowie eine untere Zentralkörperkammer 4b aufweist, die über ein Rückschlagventil 20 mit der oberen Zentralkörperkammer verbunden ist. Die Schutzkappe 11 ist im Bereich unterhalb des Rückschlagventils 20 angeordnet und mit dem Zentralkörper verschweißt.In the embodiment according to FIGS. 4 and 5, the ventilation device is inserted into a screw cap 21 which is screwed onto the collar of the collar opening. The opening protection device 16 is a cap which is formed from sheet metal or film and is fastened to the flat cover 13. The reference numerals already explained have been entered in FIGS. 4 and 5 because the embodiment according to FIGS. 4 and 5 in this respect corresponds to the embodiment according to FIGS. 2 and 3. Special recesses are provided as the passage 12. However, the arrangement is otherwise made in FIGS. 4 and 5 so that the central body 4 protrudes toward the container interior over the bottom 5, so that the central body 4 has an upper central body chamber 4a, in which the filter substance 10 is arranged, and a has lower central body chamber 4b, which is connected to the upper central body chamber via a check valve 20. The protective cap 11 is arranged in the area below the check valve 20 and welded to the central body.
