Abstract

In sterile bag-in-box filling and emptying systems for the storage, transportation and removal, even in stages, of liquids, such as pasteurised fruit beverages and the like, there is a risk of reinfection, with the result that not only the stored liquids frequently perish, but also the contents of the fruit yoghurt pots filled in relatively large quantities with said liquids. Additionally, great investment costs have to be raised for the equipment and high costs for cleaning and maintenance are incurred with each new filling of the current plants. In order to achieve greater safety from reinfection and to reduce the costs both for procurement and for current operation, the plastic bag (1) is hermetically sealed and produced in a sterile manner, and inserted into the valve unit (2), the opening of said bag having a circular sealing ring (3), the inside surface of which is provided with a sealing skin (4) which is removed when it is destroyed by the incoming liquid.

Description

Die Erfindung geht aus von einem Flüssigkeitsbehälter, bestehend aus einem formstabilen Außenbehälter und einem darin eingesetzten, flexiblen Kunststoffsack, wobei der Kunststoffsack einen Füll- und Entnahmestutzen mit einer an dessen freiem Ende einstückig ausgebildeten, ringförmigen Erweiterung aufweist und wobei der Füll- und Entnahmestutzen im unteren Bereich des Außenbehälters in dessen Füll- und Entnahmeöffnung fixiert ist. Ein derartiger Behälter ist bekannt aus der FR-A-2 371 355.The invention relates to a liquid container, consisting of a dimensionally stable outer container and a flexible plastic bag inserted therein, the plastic bag having a filling and removal nozzle with an annular extension formed integrally at its free end, and wherein the filling and removal nozzle in the lower Area of the outer container is fixed in the filling and removal opening. Such a container is known from FR-A-2 371 355.

Mit solchen Behältern werden Flüssigkeiten, wie pasteurisierte Fruchtzubereitungen, auch Fruchtgrundstoff genannt, oder andere Flüssigkeiten, bei denen eine sterile, aseptische oder keimarme Behandlung erforderlich ist, transportiert, gelagert sowie nach Bedarf auch in Etappen entnommen. Hierbei werden entweder im Mehrweg-Betriebssystem transportable, rostfreie Edelstahldruckbehälter verwendet, in die die Flüssigkeiten direkt eingebracht werden, meist mit einem Fassungsvermögen von etwa 100 bis 2.000 Liter, oder es werden bereits Behälter aus einem formstabilen Außenbehälter, wie aus Metall oder aus Karton, und einem darin eingesetzten flexiblen Kunststoffbeutel bzw. -sack für den Einweg- oder Mehrwegbetrieb angewendet.With such containers, liquids, such as pasteurized fruit preparations, also called fruit base, or other liquids that require sterile, aseptic or low-germ treatment, are transported, stored and, if necessary, also removed in stages. Either transportable, stainless steel pressure vessels are used in the reusable operating system, into which the liquids are introduced directly, usually with a capacity of about 100 to 2,000 liters, or containers made of a dimensionally stable outer container, such as made of metal or cardboard, and a flexible one used in it Plastic bag or sack used for one-way or reusable operation.

Es ist ein Flüssigkeitsbehälter bekannt (NL-A-8 303 120), bei dem ein in ein Faß einzusetzender leerer Beutel mit einem Anschlußstutzen ausgerüstet ist, dessen Öffnung mit einem Abdichtelement verschlossen ist, so daß das Innere des Beutels völlig nach außen abgedichtet ist. Nach festem Einsetzen des Anschlußstutzens in ein Faß wird vor dem Befüllen des Beutels ein Abfüllrohr in den Anschlußstutzen eingesetzt und damit das Abdichtelement durchstochen. Nachteilig ist hierbei, daß vor dem Einsetzen des Füllrohres in den Anschlußstutzen beide Teile innen und außen sowie die Öffnung nach dem Herausnehmen des Füllrohres und auch ein dann einzusetzender Stopfen zum Verschließen Verschmutzungen ausgesetzt ist, wodurch die Sterilität beim Einfüllen nicht gewährleistet ist. Außerdem ist hierbei sowohl die Frage der etappenweisen, sterilen Entnahme von Flüssigkeit als auch die Füllung und Entnahme bei großen Beuteln an deren Unterseite nicht gelöst.A liquid container is known (NL-A-8 303 120) in which an empty bag to be inserted into a barrel is equipped with a connecting piece, the opening of which is closed with a sealing element, so that the inside of the bag is completely sealed off from the outside. After the connection piece has been firmly inserted into a barrel, a filling tube is inserted into the connection piece before the bag is filled, and the sealing element is thus pierced. The disadvantage here is that before inserting the filling tube into the connecting piece, both parts inside and outside, as well as the opening after removing the filling tube and also a stopper to be inserted, are soiled, so that sterility when filling is not guaranteed. In addition, the question of the step-by-step, sterile removal of liquid as well as the filling and removal of large bags on their underside is not solved.

Ein ebenfalls bekanntgewordener Vorschlag dieser Art (FR-A-2 371 355) kommt einmal auch nur für kleine Behälter in Betracht, da die offene Folienhülle durch den kleinen Abflußstopfen in das Faßinnere eingesteckt werden muß, und zum anderen sind für eine sterile Einfüllung und etappenweise Entnahme keine Vorkehrungen getroffen.A proposal of this type which has also become known (FR-A-2 371 355) comes into consideration only for small containers, since the open film envelope must be inserted into the interior of the barrel through the small drain plug, and on the other hand for sterile filling and in stages No precautions have been taken.

Der Erfindung liegt die Aufgabe zugrunde, die bekannten Behälter so weiterzubilden, daß der im Inneren sterilisierte Kunststoffsack und die einzufüllende Flüssigkeit beim Befüllen und einfachen Bedienungsaufwand garantiert steril bleiben, wobei ohne zusätzliche Bauteile eine dichtende Verbindung zwischen Außen- und Innenbehälter sowie der angeschlossenen Armatur gewährleistet sein soll und zudem die Armaturanschlüsse der Außenbehälter den bisherigen entsprechen bzw. so gestaltet sind, daß die eingeführten Armaturen unverändert verwendbar sind.The invention has for its object to develop the known container so that the inside sterilized plastic bag and the liquid to be filled guaranteed to remain sterile when filling and simple operation, with a sealing connection between without additional components Outer and inner container and the connected fitting should be guaranteed and also the fitting connections of the outer container correspond to the previous ones or are designed so that the inserted fittings can be used unchanged.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß der Füll- und Entnahmestutzen als flexibles Schlauchstück abschließend mit einem flexiblen Dichtungsring versehen ist sowie die Mündung desselben durch eine verhältnismäßig dünne Membrane hermetisch verschlossen ist und daß der Dichtungsring zwischen einer Stirnfläche eines an der Füll- und Entnahmeöffnung des Außenbehälters vorhandenen Stutzens bzw. Gewindestutzens und einem daran anschließenden Füll- und Entleerungsventil eingeklemmt ist.This object is achieved in that the filling and removal nozzle as a flexible piece of hose is finally provided with a flexible sealing ring and the mouth of the same is hermetically sealed by a relatively thin membrane and that the sealing ring between an end face of one at the filling and removal opening of the Outer container existing connector or threaded connector and an adjoining filling and emptying valve is clamped.

Vorteilhafte Weiterbildungen der Erfindung ergeben sich aus den Unteransprüchen.Advantageous developments of the invention result from the subclaims.

Die mit der Erfindung erzielten Vorteile bestehen insbesondere darin, daß beim Befüllen von Flüssigkeitsbehältern - auch Getränkecontainern genannt - mit in einem formstabilen Außenbehälter eingelegten Kunststoffsack zur Aufnahme der Flüssigkeit eine Infektion des Inhalts mit Sicherheit ausgeschlossen ist und somit Reklamationen bei eingetretener Reinfektion des Inhalts nicht anerkannt werden müssen, wobei umfangreiche, die Füllpartien nach außen abschließende Automaten nicht erforderlich sind. Außerdem ist es günstig, daß besondere Vorkehrungen nicht getroffen werden müssen bzw. daß es erst durch die Erfindung ermöglicht ist, alle vorkommenden Außenbehälter, vom sperrigen Edenstahl-Großcontainer bis zum Karton mittlerer bis kleinerer Größe, unabhängig von ihrer Bauart befüllen zu können und auch die dazugehörigen vorhandenen Armaturen unverändert zu verwenden. Durch die erfindungsgemäße Ausgestaltung des Füll- und Entnahmestutzens ist auch ein Schutz desselben, insbesondere der Membrane, und eine einfache Sterilisation seiner Außenfläche bis zur Befüllung ermöglicht.The advantages achieved by the invention are, in particular, that when filling liquid containers - also called beverage containers - with a plastic bag inserted in a dimensionally stable outer container to hold the liquid, infection of the content is excluded with certainty and thus complaints are not recognized when the content is reinfected extensive automatic machines that close off the filling parts are not required. In addition, it is favorable that special precautions do not have to be taken or that it is only made possible by the invention to be able to fill all occurring outer containers, from bulky Eden steel large containers to medium-sized and small cardboard boxes, regardless of their design, and also that associated existing fittings unchanged use. The inventive design of the filling and removal nozzle also allows protection of the same, in particular the membrane, and simple sterilization of its outer surface until it is filled.

A stainless steel container 2 shown in FIG. 1 consists of an outer container 4, a support frame 6 and a filling and removal valve unit 8 and has a manhole 12 at the top through which an empty plastic bag 14 is to be introduced, the hook 20 of a lid 10 of the outer container 4 via traction means 16, which at its eyelets 18th connect differently, is hung.

An einem Ventilanschlußteil 21 des Außenbehälters 4, wie es auch Fig. 2 deutlicher zeigt, ist ein Stutzen 22 angeschweißt, wobei ihm eine Überwurfmutter 24 zugeordnet ist.A nozzle 22 is welded to a valve connecting part 21 of the outer container 4, as is also shown more clearly in FIG. 2, with a union nut 24 being associated with it.

Mittels des Stutzens 22 ist ein inneres Ventilteil 26 der Füll- und Entnahmeventileinheit 8 angeschlossen. Der am Kunststoffsack 14 befindliche Füll- und Entnahmestutzen 28 kann bequem nach Öffnen seines Loches 30 durch Entfernen eines Verschlußteils 32 erfaßt und durch das Ventilanschlußteil 21 und den Kegelstutzen 22 so eingesetzt werden, daß ein O-ringförmiger Dichtungsring 34 des Füll- und Entnahmeschlauchstückes 28 vor einer Stirnfläche 36 des Kegelstutzens 22 liegt.An inner valve part 26 of the filling and removal valve unit 8 is connected by means of the connector 22. The filling and removal nozzle 28 located on the plastic bag 14 can be conveniently grasped after opening its hole 30 by removing a closure part 32 and inserted through the valve connecting part 21 and the conical nozzle 22 such that an O-ring-shaped sealing ring 34 of the filling and removal hose piece 28 is in front an end face 36 of the conical nozzle 22.

Ein Verschlußteil 32 ist dadurch schnell abnehmbar und wieder einzusetzen, weil es von einem Haltekeil 38 fest montiert wird, der mittels außerhalb des Verschlußteils 32 vorhandener Halter 40 sein Gegenlager findet, wobei über eine Dichtschnur 42 bei Bedarf abgedichtet werden kann. Anschließend ist die Füll- und Entnahmeventileinheit 8 zu montieren, und zur Sterilisation von Innenräumen 45 derselben wird in an sich bekannter Weise vor der Befüllung des im Außenbehälter 4 einliegenden Kunststoffsackes 14 über ein Rohrstück 43 z. B. Heißdampf eingelassen, wobei wenigstens zeitweise die Überwurfmutter 24 so gelöst werden, daß der Heißdampf durch diese Gewindesitze entweichen kann.A closure part 32 is thereby quickly removable and reinsert, because it is firmly mounted by a retaining wedge 38, which finds its counter bearing by means of holder 40 present outside the closure part 32, it being possible to seal via a sealing cord 42 if necessary. Subsequently, the filling and removal valve unit 8 is to be mounted, and for sterilizing interiors 45 of the same, in a manner known per se, before filling the plastic bag 14 lying in the outer container 4 via a pipe section 43, for. B. superheated steam, the union nut 24 being loosened at least temporarily, that the hot steam can escape through these threaded seats.

Der Dichtungsring 34 bildet mit einem Schlauchteil 44 und einer Membrane 46 den Füll- und Entnahmestutzen 28, der je nach den Einbau- und Betriebsbedingungen des Anwendungsfalles und somit auch denen der Außenbehältnisse entsprechend dimensioniert ist. Der Dichtungsring 34 ersetzt den bei vorhandenen Einrichtungen dieser Art verwendeten sonstigen Dichtring, er ist deshalb zum Schlauchteil 44 an dessen Außenbereich vorgesehen. Nach den jeweiligen Betriebsbedingungen richten sich auch die Materialqualitäten und Abmessungen des Kunststoffsackes sowie ebenso die Teile des Füll- und Entnahmestutzens 28.The sealing ring 34, together with a hose part 44 and a membrane 46, forms the filling and removal nozzle 28, which is dimensioned accordingly depending on the installation and operating conditions of the application and thus also those of the outer containers. The sealing ring 34 replaces the other sealing ring used in existing devices of this type, it is therefore provided for the hose part 44 on the outside thereof. The material qualities and dimensions of the plastic bag as well as the parts of the filling and removal nozzle 28 also depend on the respective operating conditions.

Die Membrane 46 kann verdünnte oder eingekerbte Partien 100 bzw. Stellen aufweisen, durch die ein leichteres Einreißen gegeben ist, wobei zweckmäßigerweise durch eine sternförmige Ausbildung ein Aufbruch der Abdichthaut von der Mitte aus nach außen eingeleitet wird, damit die Reststücke möglichst kurz sind und nicht mit den zu verschwenkenden Ventilteilen, wie einer Platte 98, kollidieren.The membrane 46 can have thinned or indented areas 100 or places through which there is easier tearing, wherein a star-shaped configuration expediently initiates an opening of the sealing skin from the center outwards so that the remaining pieces are as short as possible and not with the valve parts to be pivoted, such as a plate 98, collide.

Das Schlauchteil 44 ist auf ein Rohrstück 47 eines Spundflansches 48, der mit Halterillen 50 zum festeren Sitz versehen ist, aufgezogen, wobei in üblicher Weise der Spundflansch 48 um ein Spundloch 52 des Kunststoffsackes 14 mit diesem verschweißt ist.The tube part 44 is drawn onto a pipe section 47 of a sheet pile flange 48, which is provided with retaining grooves 50 for a more secure fit, the sheet pile flange 48 being welded to the plastic bag 14 in a conventional manner about a sheet pile hole 52.

Eine Füll- und Entnahmeventileinheit 54 nach den Fig. 3 und 4 ist für Ein- und Mehrwegaußenbehältnisse 55 vorgesehen, die aus Karton, einer Kiste oder dergleichen bestehen können.A filling and removal valve unit 54 according to FIGS. 3 and 4 is provided for one-way and reusable outer containers 55, which can consist of cardboard, a box or the like.

Ein Gewindestutzen 60 ist in ein Loch 58 einer Kartonseitenwand 56 eingesetzt, wobei eine Außenscheibe 62 mit Gewinde auf den Gewindestutzen 60 feststehend aufgeschraubt und das Gewinde nur so lange ausgeführt ist, daß ein Freimaß 63 zur Überwurfmutter 24 erhalten bleibt. Anderseitig wird eine Nutmutter 66 aufgeschraubt, die gegen eine Innenscheibe 70, welche mit ihrem Innendurchmesser mit einem Lossitz auf dem Gewindestutzen 60 angeordnet ist, zur Wirkung kommt. Hierdurch wird die Füll- und Entnahmeventileinheit 54 um die Kartonseitenwand 56 festspannend angeordnet, wobei der solide Sitz derselben um die Kartonseitenwand 56 durch die verhältnismäßig große Ausführung der Außen- und Innenscheibe 62 bzw. 70 erreicht wird.A threaded connector 60 is inserted into a hole 58 in a cardboard side wall 56, an outer washer 62 with thread being screwed onto the threaded connector 60 and the thread being carried out only so long that a clearance 63 to the union nut 24 is retained. On the other hand, a lock nut 66 is screwed on, which comes into effect against an inner disk 70, which is arranged with its inner diameter with a loose fit on the threaded connector 60. As a result, the filling and removal valve unit 54 is arranged so as to tighten around the cardboard side wall 56, the solid fit of which around the cardboard side wall 56 is achieved by the relatively large design of the outer and inner disks 62 and 70, respectively.

Die Außen- bzw. Innenscheibe 62 bzw. 70 ist jeweils in ihrem unteren Bereich 74 verkürzt ausgeführt, so daß die Füll- und Entnahmeventileinheit 8 möglichst nah zum Boden 76 des Außenbehältnisses 55 vorgesehen werden kann, um einen fast restlosen Auslauf der Flüssigkeit zu gewährleisten, wobei die Außenscheibe 62 als Winkelstück ausgebildet sein kann, deren unterer schenkel unter dem Boden 76 zur Anlage kommt.The outer and inner disks 62 and 70 are each shortened in their lower region 74, so that the filling and removal valve unit 8 can be provided as close as possible to the bottom 76 of the outer container 55 in order to ensure an almost complete discharge of the liquid, the outer pane 62 can be designed as an angle piece, the lower leg of which comes to rest under the base 76.

Das einstückige Füll- und Entnahmeschlauchstück 68 wird aus einem O-ringartigen Dichtungsring 80, einer Membrane 82 und einem Schlauchteil 78 gebildet, wobei letzteres auf einem kurzen Rohrstück 84 eines Spundflansches 86 aufgezogen ist und wobei dasselbe über ein Klemmband 88 zusätzlich gehaltert wird.The one-piece filling and removal hose piece 68 is formed from an O-ring-like sealing ring 80, a membrane 82 and a hose part 78, the latter on a short pipe piece 84 Sheet flange 86 is mounted and the same is additionally held by a clamping band 88.

Der Spundflansch 86 ist mit einem Kunststoffsack 90 verschweißt. Das Einsetzen des Füll- und Entnahmestutzens 68 sowie das Anschließen und Sterilisieren der nur kurz angedeuteten Füll- und Entnahmeventileinheit 8 erfolgt in gleicher Weise, wie bei dem Ausführungsbeispiel der Fig. 1 und 2 bereits beschrieben.The sheet flange 86 is welded to a plastic bag 90. The filling and removal nozzle 68 is inserted and the filling and removal valve unit 8, which is only briefly indicated, is connected and sterilized in the same way as already described for the exemplary embodiment in FIGS. 1 and 2.

In den Fig. 5 bis 9 sind einige Varianten der vorderen Partie von Füll- und Entnahmeschlauchstücken 28 bzw. 68 gezeigt.5 to 9, some variants of the front section of filling and removal hose pieces 28 and 68 are shown.

Bei der Ausführung gemäß den Fig. 5 und 9 ist eine einstückige Bauweise des gesamten Füll- und Entnahmestutzens 28 gewählt, wobei vom Dichtungsring 34 des Schlauchteils 44 zunächst etwas nach innen verlaufend anschließt, damit es beispielsweise in vorhandene oder entsprechend ausgebildete Ventileinheiten eingesetzt werden kann.5 and 9, a one-piece construction of the entire filling and removal nozzle 28 is selected, with the sealing ring 34 of the hose part 44 initially running somewhat inwards so that it can be used, for example, in existing or appropriately designed valve units.

Beim Ausführungsbeispiel gemäß Fig. 6 eines Füll- und Entnahmestutzens 102 sind eine Abdichthaut 104 und ein Schlauchteil 106 mit einem Dichtungsring 108 durch Verschweißen hermetisch verbunden.In the exemplary embodiment according to FIG. 6 of a filling and removal nozzle 102, a sealing skin 104 and a hose part 106 are hermetically connected to a sealing ring 108 by welding.

Die Fig. 7 zeigt eine Ausführung eines Füll- und Entnahmestutzens 110, bei der der Dichtungsring 112 mit einer Abdichthaut 114 und einem Schlauchanschlußstück 116 einstückig hergestellt ist, wobei letzteres ebenfalls mit Halterillen 118 versehen ist, wodurch ein aufgeschobenes Schlauchteil 120 einen festen Halt erfährt.Fig. 7 shows an embodiment of a filling and removal nozzle 110, in which the sealing ring 112 is made in one piece with a sealing skin 114 and a hose connector 116, the latter also being provided with retaining grooves 118, whereby a pushed-on hose part 120 experiences a firm hold.

Die Bauart eines Füll- und Entnahmeschlauchstückes 124 nach Fig. 8 weist ein einteiliges Abdichthaut- und Schlauchanschlußstück 126 auf, das mit einem O-ringförmigen Dichtungsring 128 verschweißt ist.The construction of a filling and removal hose piece 124 according to FIG. 8 has a one-piece sealing skin and hose connection piece 126, which is welded to an O-ring-shaped sealing ring 128.

Weitere Hilfsgeräteteile sind für den störungsfreien Betrieb von Vorteil. So können, insbesondere für größere Anlagen, bei denen der Flüssigkeitsdruck in Bodennähe hoch ist, für die Halterung des Füll- und Entnahmestutzens 28 im Bereich der Innenräume der Behältnisse Halter 96 vorgesehen sein, so daß die Füll- und Entnahmestutzen 28 hier nicht zusammengedrückt werden können, wodurch Beschädigungen möglich wären und der Auslauf der Flüssigkeit gehemmt bzw. unterbunden werden könnte. Die Halter 96 können mit den Außenbehältnissen fest verbunden werden, sie können aber auch nur eingesetzt sein und/oder über geeignete, bekannte Mittel, wie Steckverbindungen oder dergleichen, lagegesichert werden.Additional auxiliary device parts are advantageous for trouble-free operation. So, especially for larger systems in which the liquid pressure near the ground is high, holder 96 can be provided for holding the filling and removal nozzle 28 in the region of the interior of the containers, so that the filling and extraction nozzle 28 cannot be compressed here , which could cause damage and prevent or prevent the liquid from escaping. The holders 96 can be firmly connected to the outer containers, but they can also only be inserted and / or secured in position by means of suitable, known means, such as plug connections or the like.
