Description

Die Erfindung betrifft ein Ausgiesselement für eine Verpackung, insbesondere eine Verbundverpackung für flüssige Lebensmittel, mit einem Grundkörper, einem polyederförmigen Flansch, dessen Flanschinnenflächen in Flächenanstössen zusammenlaufen, zur Verbindung mit einem Verpackungsmantel und wenigstens einem an der Flanschinnenseite auskragenden Halteelement zur Wirkverbindung mit einem Dorn einer Verpackungsmaschine sowie eine Verbundverpackung für flüssige Lebensmittel mit polyederförmigen Giebelflächen.The invention relates to a pouring element for a packaging, in particular a composite packaging for liquid food, comprising a main body, a polyhedron-shaped flange, the flange inner surfaces converge in Flächenanstössen for connection to a packaging casing and at least one projecting on the flange inside holding element for operative connection with a mandrel of a packaging machine and a composite packaging for liquid foods with polyhedral gable surfaces.

Im Bereich der Verpackungstechnik gehören Verbundverpackungen seit langem zum gängigen Stand der Technik. So bestehen beispielsweise Getränkekartons aus verschiedenen Packstoffen wie Papier und Kunststoffen, die, vollflächig gefügt und bedruckt, ein Packungslaminat bilden. Der Schichtaufbau kann je nach Anforderungen variieren, so wird beispielsweise für aseptische Füllgüter zusätzlich eine Aluminiumschicht eingelegt, um eine gute Barrierewirkung gegen Gase und Licht zu erzielen. Oft - aber nicht immer - wird das Laminat noch während seiner Herstellung auf Verpackungsgrösse zugeschnitten und auf diese Weise sogenannte Verpackungsmäntel gebildet. Alternativ wird oft auch das Packungslaminat als Rollenware ausgeliefert und erst später zugeschnitten.In the field of packaging technology, composite packaging has long been part of the state of the art. For example, beverage cartons consist of various packaging materials, such as paper and plastics, which form a package laminate over the entire surface and printed. The layer structure can vary depending on the requirements, for example, for aseptic filling materials additionally an aluminum layer is inserted in order to achieve a good barrier effect against gases and light. Often - but not always - the laminate is cut to size during packaging and thus formed so-called packaging coats. Alternatively, often the package laminate is delivered as a roll and cut later.

Das eigentliche Formen und Befüllen der Verpackung und das Verschliessen zu einer Packung geschieht in einer Verpackungsmaschine, die nicht selten in Anlehnung an ihre Hauptfunktionen auch als Form-/Fill-/Seal-Maschine bezeichnet wird. Als Füllgüter kommen vorwiegend flüssige Lebensmittel wie beispielsweise Getränke, Suppen, Joghurt oder dergleichen in Frage.The actual forming and filling of the packaging and the closure into a package takes place in a packaging machine, which is often referred to as a form - / fill / seal machine based on its main functions. The contents are mainly liquid foods such as drinks, soups, yogurt or the like in question.

Solche Verpackungen werden zuweilen auch mit Ausgiesselementen versehen. Diese ermöglichen dem Verbraucher neben einem kontrollierten Ausgiessen in der Regel auch eine Wiederverschlussmöglichkeit. Nicht selten und vorwiegend bei aseptischer Anwendung ist zudem eine Erstöffnungsfunktion für die Packung vorgesehen. Dabei wird die zuvor gasdicht verschlossene Packung erstmalig aufgetrennt. Dies kann beispielsweise mittels Zug-Ring ("Ring-Pull") oder -Lasche oder auch durch eine Stech- und/oder Schneidvorrichtung geschehen. Solche Stech- und/oder Schneidvorrichtungen sind oft als Schneidringe ausgeführt, die über Antriebsmittel mit beispielsweise der Schraubkappe gekoppelt sind, so dass - mittels der Drehbetätigung der Schraubkappe - die Packung gleichzeitig aufgeschnitten wird.Such packages are sometimes also provided with Ausgiesselementen. These allow the consumer in addition to a controlled pouring usually also a reclosure option. Not uncommon and predominantly aseptic Application is also provided a Erstöffnungsfunktion for the pack. The previously gas-tight sealed package is first separated. This can be done for example by means of pull-ring ("ring-pull") or -Lasche or by a piercing and / or cutting device. Such piercing and / or cutting devices are often designed as cutting rings, which are coupled via drive means with, for example, the screw cap, so that - by means of the rotary actuation of the screw cap - the package is cut simultaneously.

Ein Ausgiesselement genannter Art zeigt beispielsweise die auf den Anmelder zurückgehende WO 2012/048935 A1 . Dieses besteht im Wesentlichen aus einem mit einer Schraubkappe verschlossenen Grundkörper, welcher neben dem eigentlichen Ausgiesstubus auch einen Flansch zur Verbindung mit übrigen Verpackungsteilen (hier einem Verpackungsmantel) aufweist. Die Ausgiesselemente werden während des Formprozesses der Verpackung und vor der eigentlichen Befüllung in diese eingearbeitet und bilden so einen Teil der Verpackung. Je nach Verpackungsform und -art wird das Ausgiesselement von innen durch ein vorgestanztes Loch im Flachgiebel der Verpackung appliziert. Der Flansch des Ausgiessers erstreckt sich dann parallel zur Ebene des Flachgiebels der Verpackung, wie dies im ersten dort gezeigten Ausführungsbeispiel offenbart ist. Es ist aber auch möglich, dass das Ausgiesselement selbst den Kopfbereich der Verpackung bildet, wie dies im weiter dargestellten Ausführungsbeispiel gezeigt ist. Der Verbindungsflansch ragt dabei gewinkelt vom eigentlichen Ausgiesselement ab und bildet einen polyederförmigen Flansch, der hier im Wesentlichen einem Pyramidenstumpf entspricht.A pouring element of the type mentioned, for example, the originating from the applicant WO 2012/048935 A1 , This consists essentially of a sealed with a screw cap body, which in addition to the actual Ausgiesstubus also has a flange for connection with other packaging parts (here a packaging casing). The Ausgiesselemente be incorporated during the molding process of the package and before the actual filling in this and thus form part of the packaging. Depending on the form and type of packaging, the pouring element is applied from the inside through a pre-punched hole in the flat gable of the packaging. The flange of the spout then extends parallel to the plane of the flat gable of the package, as disclosed in the first embodiment shown there. But it is also possible that the Ausgiesselement itself forms the top portion of the package, as shown in the further illustrated embodiment. The connecting flange protrudes angled from the actual pouring element and forms a polyhedron-shaped flange, which essentially corresponds here to a truncated pyramid.

Das Einarbeiten und Verbinden findet meist in einer bereits eingangs erwähnten Verpackungsmaschine statt. Eine solche ist in der auf den Anmelder zurückgehenden WO 2012/062565 A1 offenbart. Dort zeigt Figur 5 im linken Bereich ein Dornrad mit neun, über seinen Umfang angeordneten Arbeitsdornen (kurz: Dorne). Im rechten Abschnitt ist die hier nicht weiter interessierende Befüllanlage angeordnet. In Betrieb dreht das Dornrad zyklisch, so dass die Dorne zwischen einzelnen Arbeitspositionen (I bis IX) verdrehen und für die zu vollziehenden Arbeitsschritte in diesen Positionen verharren, um das Ausgiesselement mit dem Mantel zu verbinden und im Wesentlichen den Kopfbereich der Verpackung zu bilden. In der Arbeitsposition I wird das Ausgiesselement von einer Zuführeinrichtung auf den noch leeren Dorn verbracht. Darauf rotiert das Dornrad, um den mit dem Ausgiesselement beschickten Dorn in Arbeitsposition II zu bringen, in dem ein Verpackungsmantel auf den Dorn übergeschoben wird. In den Arbeitspositionen III und IV erfahren Ausgiesselement und Verpackungsmantel in den Bereichen der späteren Verbindungsstellen eine thermische Heissluftaktivierung, d. h. der Kunststoff wird örtlich aufgeschmolzen. In Arbeitsposition V werden dann die aktivierten Flächen aufeinandergepresst, so dass eine feste und dauerhafte Verbindung geschaffen wird. Die nachfolgenden Arbeitspositionen VI und VII legen die durch die Herstellung des pyramidenstumpfförmigen Verpackungsgiebels entstehenden, überstehenden Verpackungsmantelabschnitte (die sogenannten "Ohren"), an die Giebelabschnitte an. Auf Position VIII wird dann die einseitig im Giebelbereich fertiggestellte Verpackung einer Zellenkette der Befüllanlage übergeben, wo sie durch den noch offenen Bodenbereich befüllt, sodann verschlossen und der Bodenbereich endgefertigt wird. Der Position IX ist kein Arbeitsschritt zugeordnet.The incorporation and bonding usually takes place in a packaging machine already mentioned above. Such is in the case of the applicant WO 2012/062565 A1 disclosed. There, FIG. 5 shows in the left-hand region a mandrel wheel with nine working mandrels arranged over its circumference (in short: mandrels). In the right section of the here not interesting filling system is arranged. In operation, the mandrel wheel rotates cyclically, allowing the mandrels between individual working positions (I to IX) twist and remain for the steps to be performed in these positions in order to connect the pouring element with the shell and to form substantially the head portion of the package. In the working position I, the pouring element is moved from a feeder to the still empty mandrel. Then, the mandrel wheel rotates to bring the mandrel loaded with the spout into working position II, in which a packaging casing is pushed onto the mandrel. In the working positions III and IV, the pouring element and the packaging casing experience thermal hot-air activation in the areas of the later connection points, ie the plastic is locally melted. In working position V then the activated surfaces are pressed together, so that a solid and permanent connection is created. The following working positions VI and VII apply to the gable sections the projecting packaging casing sections (the so-called "ears") resulting from the production of the truncated pyramidal packing gable. At position VIII, the packaging, completed on one side in the gable area, of a cell chain is then transferred to the filling installation, where it is filled through the still open floor area, then closed and the floor area is finished. Position IX is not assigned a work step.

Das Ausgiesselement erfährt bei seiner Verbindung mit dem Verpackungsmantel erhebliche thermische und mechanische Belastungen. Es muss vorerst über die einzelnen Arbeitspositionen des Dornrades lösungssicher und in gewünschter Lage arretiert bleiben, dann wieder zusammen mit dem Verpackungsmantel freigegeben werden. Bei der Heissluftaktivierung wird das Material im Bereich des Flansches erst örtlich aufgeschmolzen, um dann im darauffolgenden Schritt mit dem Verpackungsmantel verpresst zu werden. Neben dem Halten zeitigen die Arbeitsschritte zusätzliche mechanische und thermische Belastungen für das Ausgiesselement.The pouring element experiences considerable thermal and mechanical loads when it is connected to the packaging casing. For the time being, it must remain securely locked in the desired position over the individual working positions of the mandrel wheel, then released again together with the packaging casing. In the hot air activation, the material in the region of the flange is first melted locally, in order then to be pressed in the next step with the packaging sheath. In addition to holding the work steps, additional mechanical and thermal loads for the pouring element.

Alternativ sind beispielsweise auch Ultraschall-Verbindungstechniken gängiger Stand der Technik. Auch hierbei bedingen die hochfrequenten Schwingungen und statischen Fügekräfte erhebliche weitere Belastungen für das Ausgiesselement.Alternatively, for example, ultrasonic bonding techniques are common prior art. Here too, the high-frequency vibrations and static joining forces cause considerable additional loads for the pouring element.

Für die temporäre Verbindung zwischen Ausgiesselement und Dorn sind in der Vergangenheit verschiedene Lösungen vorgeschlagen worden. Mit Vakuum arbeitende Lösungen, wie beispielsweise solchen, wie in der WO 9739958 A1 gezeigten, sind technisch aufwändig und lassen hohe Investitions- und Betriebskosten der Verpackungsmaschine entstehen. Mechanische Halterungen sind technisch einfacher und preiswerter zu realisieren, bedeuten aber durch die form- und/oder reibschlüssige Verbindung eine zusätzliche mechanische Belastungen für das Ausgiesselement.Various solutions have been proposed for the temporary connection between pouring element and mandrel in the past. With vacuum working solutions, such as those, as in the WO 9739958 A1 shown, are technically complex and can be high investment and operating costs of the packaging machine arise. Mechanical brackets are technically easier and cheaper to implement, but mean by the positive and / or frictional connection an additional mechanical loads on the Ausgiesselement.

Eine reibschlüssige Verbindung zwischen Ausgiesselement und Dorn offenbart JP 2009039980 A . Der Anmelder führte eine Untersuchung hinsichtlich Eingriffs- und Lösekräften in Abhängigkeit verschiedener Haltedornausbildungen (im Wesentlichen deren Geometrie) durch. Die Versuchsergebnisse der Versuchsreihe (inklusive schadhafter Ausgiesselemente) sind in der wiedergegebenen Tabelle ausgewiesen.A frictional connection between pouring element and mandrel is disclosed JP 2009039980 A , The Applicant conducted a study regarding engagement and release forces depending on various retaining mandrel designs (essentially their geometry). The experimental results of the test series (including faulty pouring elements) are shown in the table.

Formschlüssige Verbindungen zwischen Ausgiesselement und Dorn definieren die Lage des Ausgiessers am Dorn abschliessend hinsichtlich aller Freiheitsgrade. Eine solche Lösung ist in der auf den Anmelder zurückgehenden WO 2014060133 A1 offenbart. Ein umlaufendes Halteelement am Flansch des Ausgiessers mit einem dazu korrespondierenden Dorn gewährleisten eine zuverlässige Verbindung und ein einfaches Entfernen. Im dort gezeigten Ausführungsbeispiel ist das Halteelement als Auskragung ausgeführt.Positive connections between Ausgiesselement and mandrel define the position of the spout on the mandrel final with respect to all degrees of freedom. Such a solution is in the name of the applicant WO 2014060133 A1 disclosed. A circumferential retaining element on the flange of the spout with a corresponding mandrel ensure a reliable connection and easy removal. In the embodiment shown there, the holding element is designed as a projection.

Den verschiedenartigen Belastungen, denen ein Ausgiesselement während seiner Fertigung in der Verpackungsmaschine ausgesetzt ist, haben dieselben nicht immer standgehalten. In nicht wenigen Fällen führten versagende Ausgiesselemente zu schadhaften und/oder undichten Packungen. Die Schadensbilder reichen von gebrochenen oder gerissenen Flanschen bis hin zu fehlerhaften Verbindungsbereichen. Oft versagen die Ausgiesselemente und/oder Packungen auch erst unter ihrer Stapelung bei ihrer anschliessenden Distribution.The various loads that a pouring element is exposed to during its manufacture in the packaging machine, the same have not always withstood. In quite a few cases, failing spouts led to damaged and / or leaky packs. The damage pictures range from broken or cracked flanges to faulty connection areas. Often the Ausgiesselemente and / or packs fail only under their stacking in their subsequent distribution.

Es ist deshalb Aufgabe der vorliegenden Erfindung, ein Ausgiesselement und eine Verbundpackung der eingangs genannten und zuvor näher beschriebenen Art so auszugestalten und weiterzubilden, dass die beschriebenen Nachteile überwunden werden. Insbesondere sollen Schäden am Ausgiesselement und der Verbundverpackung vermieden und gleichzeitig ein sicherer Halt zwischen Ausgiesselement und Dorn garantiert werden.It is therefore an object of the present invention, a Ausgiesselement and a composite package of the type mentioned above and described in more detail above and further, that the disadvantages described are overcome. In particular, damage to the pouring element and the composite packaging are to be avoided and at the same time a secure hold between the pouring element and the mandrel is guaranteed.

Gelöst wird diese Aufgabe bei einem Ausgiesselement nach dem Oberbegriff von Patentanspruch 1 dadurch, dass das Halteelement im Bereich der flanschinnenseitigen Flächenanstösse als Verrundung ausgeführt ist. Eine runde Geometrie des Halteelements lässt grundsätzlich geschmeidigere mechanische Vorgänge zu als eckige. So wird ein leichtgängiges Aufsetzen und Entfernen des Ausgiesselements vom Dorn erreicht. Überdies gewährleistet die Verrundung des Halteelements in den "Eckbereichen" während sämtlichen Arbeitsschritten einen sicheren und genauen Halt auf dem Dorn. Die Verbindungsschritte können so mit einer hohen Präzision ausgeführt werden. Zudem bewirken die Rundungen, dass das Halteelement gegenüber unerwünschten Kerbwirkungen strukturmechanisch toleranter ist und so eine höhere Festigkeit aufweist. Im Ergebnis werden so thermisch oder mechanisch bedingte Spannungen im Ausgiesselement weitgehend vermieden, so dass die Struktur nicht geschwächt oder gar beschädigt wird.This object is achieved with a pouring element according to the preamble of claim 1, characterized in that the holding element is designed in the region of the flange inside surface lugs as rounding. A round geometry of the holding element allows in principle smoother mechanical processes than angular. Thus, a smooth touchdown and removal of the pouring element is achieved by the mandrel. Moreover, the rounding of the retaining element in the "corner regions" ensures a secure and accurate grip on the mandrel during all working steps. The connection steps can thus be carried out with high precision. In addition, the curves cause the retaining element to be structurally more tolerant of undesired notch effects and thus has a higher strength. As a result, so thermally or mechanically induced stresses in the pouring element are largely avoided, so that the structure is not weakened or even damaged.

Gelöst wird die der Erfindung zugrunde liegende Aufgabe ebenfalls durch eine Verbundverpackung für flüssige Lebensmittel mit polyederförmigen Giebelflächen, bei welcher diese Giebelflächen mit dem polyederförmigen Flansch eines solchen Ausgiesselements korrespondierend verbunden sind.The problem underlying the invention is also solved by a composite packaging for liquid food with polyhedron-shaped gable surfaces, in which these gable surfaces are connected to the polyhedron-shaped flange of such Ausgiesselements corresponding.

Eine weitere Lehre der Erfindung sieht vor, dass das Halteelement umlaufend ausgeführt ist. Durch den vergrösserten Kontaktbereich der Wirkverbindung zwischen Halteelement und Dorn lässt sich bei gleich bleibender Haltekraft das Halteelement in seiner Höhe reduzieren. So wird ein leichtgängigeres Aufschieben und Abziehen ermöglicht. Zudem weist ein in seiner Höhe reduziertes Halteelement eine höhere Festigkeit auf.Another teaching of the invention provides that the holding element is designed to be circumferential. Due to the enlarged contact area of the operative connection between the holding element and the mandrel, the holding element can be reduced in its height while keeping the holding force constant. So a smoother pushing on and off is possible. In addition, a reduced in height holding member has a higher strength.

Nach einer weiteren Ausgestaltung der Erfindung verläuft das Halteelement im Bereich der Unterkante des Flansches. Je weiter unten das Halteelement am polyederförmigen Flansch angeordnet ist, desto länger ist der Bereich, in dem sich der Flansch während des Aufsetzens und Entfernens elastisch verformen kann. Eine elastische Verformbarkeit ist aber unbedingt gewünscht, damit keine schadhafte plastische Verformung auftritt.According to a further embodiment of the invention, the holding element extends in the region of the lower edge of the flange. The further down the retaining element is arranged on the polyhedral flange, the longer is the area in which the flange can deform elastically during placement and removal. An elastic deformability is absolutely desired, so that no defective plastic deformation occurs.

In weiterer vorteilhafter Ausführung ist die Wirkverbindung zwischen Halteelement und Dorn formschlüssig ausgeführt. Somit ist das Ausgiesselement hinsichtlich sämtlicher Freiheitsgrade abschliessend in seiner Lage fixiert. So wird während der Arbeitsprozesse eine hohe Genauigkeit erreicht, so dass die Gefahr von schadhaften Ausgiesselementen beziehungsweise Packungen stark reduziert ist.In a further advantageous embodiment, the operative connection between the retaining element and the mandrel is executed positively. Thus, the pouring element is finally fixed in its position with respect to all degrees of freedom. Thus, a high accuracy is achieved during the work processes, so that the risk of defective Ausgiesselementen or packages is greatly reduced.

Es ist im Rahmen der Erfindung jedoch alternativ auch möglich, dass die Wirkverbindung zwischen Halteelement und Dorn reibschlüssig ausgeführt ist. Reibschlüssige Wirkverbindungen können je nach spezieller Ausgestaltung des Ausgiesselements immer dann wünschenswert sein, wenn kein "Einrasten" des Halteelements in den Dorn gewünscht ist.However, in the context of the invention, it is alternatively also possible for the operative connection between the holding element and the mandrel to be frictionally engaged. Depending on the particular design of the pouring element, frictionally engaged active connections can always be desirable if no "latching" of the holding element into the mandrel is desired.

Nach einer weiteren Lehre der Erfindung sind die flanschinnenseitigen Flächenanstösse als Hohlkehlen ausgeführt. Scharfe Übergänge der Flächen sind strukturmechanisch unvorteilhaft, so dass die negativen Ausrundungen dem Ausgiesselement eine höhere Festigkeit geben und zudem Risswachstum verhindert wird.According to another teaching of the invention, the flange inside surface lugs are designed as flutes. Sharp transitions of the surfaces are structurally unfavorable, so that the negative rounding off the Pouring element give a higher strength and also crack growth is prevented.

Eine weitere zweckmässige Ausgestaltung der Erfindung sieht vor, dass über die flanschinnenseitigen Flächenanstösse Verstärkungsrippen ausgebildet sind. Diese Strukturelemente verleihen dem Ausgiesselement besonders in den kritischen "Eckbereichen" des Flansches zusätzliche Festigkeit.A further expedient embodiment of the invention provides that reinforcing ribs are formed via the flange-side surface abutments. These structural elements give the pouring element extra strength, especially in the critical "corner areas" of the flange.

Eine andere Lehre der Erfindung sieht vor, dass der Flansch des Grundkörpers pyramidenstumpfförmig ausgebildet ist. Hierdurch lässt sich eine besonders gleichmässige Verteilung der Kräfte zwischen Ausgiesselement und Verpackungsmantel erreichen.Another teaching of the invention provides that the flange of the base body is designed in the shape of a truncated pyramid. This makes it possible to achieve a particularly even distribution of the forces between the pouring element and the packaging casing.

Eine weitere Ausführung der Erfindung sieht vor, dass der Grundkörper eine rechteckige Grundplatte aufweist, speziell kann die Grundplatte quadratisch ausgeführt sein. So wird ein verbesserter Kraftlinienverlauf im Grundkörper erreicht, ohne dass Schäden am Ausgiesselement entstehen.A further embodiment of the invention provides that the base body has a rectangular base plate, in particular, the base plate can be made square. This achieves an improved line of force in the main body without causing damage to the pouring element.

Eine weitere Art der erfindungsgemässen Ausführung sieht vor, dass die Übergänge zwischen Grundplatte und Flansch als Hohlkehlen ausgeführt sind. Die ausgekehlten Flächenübergänge sind somit fester gegenüber Spannungen und minimieren das Risiko von Schäden.Another type of inventive embodiment provides that the transitions between base plate and flange are designed as flutes. The fluted surface transitions are thus stronger against stresses and minimize the risk of damage.

Nach einer weiteren zweckmässigen Ausführungsform sind die durch die flanschinnenseitigen Flächenanstösse und der Grundplatte gebildeten Ecken als sphärische Verrundungen ausgeführt. Diese "heiklen" Eckbereiche werden so zusätzlich in ihrer Festigkeit erhöht und ermöglichen einen nicht zu Schäden führenden Kräfteverlauf zwischen den anstossenden Ebenen.According to a further expedient embodiment, the corners formed by the flange inside surface lugs and the base plate are designed as spherical fillets. These "tricky" corner areas are thus additionally increased in their strength and allow a non-damaging forces flow between the abutting levels.

Eine weitere Lehre der Erfindung sieht vor, dass der Grundkörper einen Ausgiesstubus aufweist, wobei dieser zunächst mit einem Schraubdeckel verschlossen ist. Dies ist eine besonders zweckmässige Alternative des Ausgiesselements.A further teaching of the invention provides that the base body has a pouring stub, this being initially closed with a screw cap. This is a particularly expedient alternative to the pouring element.

Nach einer weiteren Ausgestaltung der Erfindung ist der Grundkörper unterhalb des Ausgiesstubus mittels einer Stützwand geschlossen und weist eine umlaufende Schwächungszone auf. Eine solche Stützwand festigt das Ausgiesselement insbesondere im Bereich der Grundplatte und dem Ausgiesstubus zusätzlich.According to a further embodiment of the invention, the base body is closed below the Ausgiesstubus means of a support wall and has a circumferential weakening zone. Such a supporting wall additionally strengthens the pouring element, in particular in the area of the base plate and the pouring tube.

Weitere zweckmässige Ausgestaltungen sehen vor, dass eine Barrierefolie an der Stützwand anliegt, wahlweise auch, dass eine Handhabe an die Stützwand angeformt ist, um diese durch ein manuelles Ziehen entfernen zu können oder dass ein Schneidelement im Ausgiesstubus angeordnet ist, um die Stützwand im Bereich der Schwächungszone zumindest teilweise aufzuschneiden. Dies sind besonders zweckmässige Alternativen des Ausgiesselements.Further expedient embodiments provide that a barrier film rests against the support wall, optionally also that a handle is formed on the support wall in order to remove it by a manual pulling or that a cutting element is arranged in Ausgiesstubus to the support wall in the region At least partially cut open weakening zone. These are particularly useful alternatives of Ausgiesselements.

Die Erfindung ist nachfolgend anhand der ein Ausführungsbeispiel zeigenden Zeichnungen näher erläutert.The invention is explained in more detail with reference to the drawings showing an embodiment.

Fig. 1 zeigt ein bevorzugtes Ausführungsbeispiel eines erfindungsgemässen Ausgiesselementes in perspektivischer Darstellung von schräg oben. Das Ausgiesselement weist im dargestellten und insoweit bevorzugten Ausführungsbeispiel einen Grundkörper 1 und einen Schraubdeckel 2 auf. Der Schraubdeckel 2 sitzt auf einem (gut in Fig. 2 und 3 erkennbaren) Ausgiesstubus 3, der einen Teil des Grundkörpers 1 bildet. Fig. 1 shows a preferred embodiment of an inventive Ausgiesselementes in a perspective view obliquely from above. The pouring element has in the illustrated preferred embodiment a base body 1 and a screw cap 2. The screw cap 2 sits on a (well in Fig. 2 and 3 recognizable) Ausgiesstubus 3, which forms part of the base body 1.

Der Grundkörper 1 weist einen polyederförmigen - genauer pyramidenstumpfförmigen - Flansch 4 auf. Flansch 4 und Ausgiesstubus 3 ragen in entgegengesetzten Richtungen von einer quadratischen Grundplatte 5 ab und bilden gemeinsam den eigentlichen Grundkörper 1. Die Form des polyederförmigen Flansches 4 ist an die Form und insbesondere an den Neigungswinkel des Giebelbereichs eines (nicht dargestellten) Verpackungsmantels angepasst. Der Giebelbereich der Verpackung ist also mindestens in dem an den Flansch 4 anschliessenden Bereich ebenfalls pyramidenstumpfförmig ausgebildet.The main body 1 has a polyhedron-shaped - more precisely truncated pyramid - flange 4. Flange 4 and pouring tube 3 protrude in opposite directions from a square base plate 5 and together form the actual base body 1. The shape of the polyhedral flange 4 is adapted to the shape and in particular to the angle of inclination of the gable region of a (not shown) packaging casing. The gable region of the packaging is thus also formed in the shape of a truncated pyramid, at least in the region adjoining the flange 4.

Die abgewinkelten Aussenflächen des Flansches 4 weisen Aussenrippen 6 auf, die einerseits den Flansch 4 mechanisch verstärken und andererseits eine bessere Anbindung der Giebelflächen des Packungsmantels beim Versiegeln mit dem Flansch 4 ermöglichen. In jedem Eckbereich ist ein flügelartiger Ansatz an den Flansch 4 angeformt. Auch die Ansätze dienen dazu, die Verbindung zwischen dem Giebelbereich des Packungsmantels und dem Flansch 4 des Ausgiesselements zu verbessern.The angled outer surfaces of the flange 4 have outer ribs 6, on the one hand strengthen the flange 4 mechanically and on the other hand allow a better connection of the gable surfaces of the packing jacket when sealing with the flange 4. In each corner a wing-like approach to the flange 4 is formed. The lugs also serve to improve the connection between the gable area of the packing jacket and the flange 4 of the pouring element.

Bei dem in Fig. 1 dargestellten Ausgiesselement verbindet ein Originalitätssiegel 7 mit als Sollbruchstellen ausgebildeten Materialbrücken (nicht näher bezeichnet) den Grundkörper 1 mit dem Schraubdeckel 2. Beim erstmaligen Öffnen werden die Materialbrücken zerstört, so dass ein Konsument leicht erkennen kann, ob eine mit diesem Ausgiesselement versehene Packung zuvor schon einmal geöffnet worden ist.At the in Fig. 1 illustrated Ausgiesselement connects a tamper-evident seal 7 with material bridges designed as predetermined breaking points (unspecified) the base body 1 with the screw 2. At the first opening the material bridges are destroyed, so that a consumer can easily recognize whether a pack provided with this Ausgiesselement before ever has been opened.

Fig. 2 zeigt das erfindungsgemässe Ausgiesselement in einer perspektivischen Darstellung von schräg unten. Der polyederförmige Flansch 4 weist auf seiner Innenseite entsprechende Flanschinnenflächen 8 auf, die im Bereich, in welchem sie zusammenlaufen, Flächenanstösse 9 bilden. Der Flansch 4 endet in einer Unterkante 10. Im Bereich dieser Unterkante 10 verläuft ein auskragendes, umlaufendes Halteelement 11, das sich kontinuierlich über sämtliche Flanschinnenflächen 8 erstreckt. Das Halteelement 11 schafft während der Bildung des Packungskopfs und Giebelbereichs eine mechanische Verbindung mit einem freien Ende eines Dornes einer Verpackungsmaschine (nicht dargestellt). Im Bereich der flanschinnenseitigen Flächenanstösse 9 ist das Halteelement 11 als Verrundung 12 ausgeführt, so dass ein leichtgängiges Aufsetzen und Entfernen ermöglicht wird. Während sämtlicher Arbeitsschritte bleibt das Ausgiesselement sicher und präzise gehalten. Fig. 2 shows the inventive pouring element in a perspective view obliquely from below. The polyhedron-shaped flange 4 has on its inside corresponding flange inner surfaces 8, which form in the area in which they converge, surface lugs 9. The flange 4 terminates in a lower edge 10. In the region of this lower edge 10 extends a projecting, circumferential retaining element 11, which extends continuously over all Flanschinnenflächen 8. The support member 11 provides a mechanical connection with a free end of a mandrel of a packaging machine (not shown) during formation of the package head and gable area. In the area of the flange inside surface lugs 9, the holding member 11 is designed as a rounding 12, so that a smooth placement and removal is possible. During all work steps, the pouring element remains safe and precise.

Im dargestellten und insofern bevorzugten Ausführungsbeispiel sind zudem die Flächenanstösse 9 als Hohlkehlen 13 ausgeführt. Flanschinnenseitig sind zudem im Bereich der Flächenanstösse 9 Verstärkungsrippen 14 angeformt, die die Festigkeit in den Eckbereichen zusätzlich erhöht. Die Bereiche der Flächenübergänge zwischen den Flanschinnenflächen 8 des Flansches 4 und der Innenfläche der Grundplatte 5 sind ebenfalls als negative Ausrundungen, also als Hohlkehlen 15, ausgeführt. Die zwischen den flanschinnenseitigen Flächenanstössen 9 und der Grundplatte 5 gebildeten Ecken sind als sphärische Verrundungen 16 ausgeführt.In the illustrated and therefore preferred embodiment, the surface lugs 9 are also designed as flutes 13. Flange inside, 9 reinforcing ribs 14 are also formed in the area of the surface abutments, which additionally increases the strength in the corner regions. The regions of the surface transitions between the flange inner surfaces 8 of the flange 4 and the inner surface of the base plate 5 are also designed as negative fillets, that is, as fillets 15. The corners formed between the flange inside surface abutments 9 and the base plate 5 are designed as spherical fillets 16.

In der vertikal geschnittenen Darstellung von Fig. 3 erkennt man ferner, dass die Unterseite des Ausgiesstubus 3 im Originalitätszustand von einer Stützwand 17 verschlossen ist. Diese ist über eine Schwächungszone 18 mit dem Grundkörper 1 verbunden. Ein (nicht dargestelltes) Schneidelement schneidet beim erstmaligen Abdrehen des Schraubdeckels 2 die Schwächungszone 18 durch und legt so den Durchgang des Ausgiesstubus 3 zum Ausgiessen frei. Um eine ausreichende Haltbarkeit und Aromaschutz des abgefüllten Produkts zu garantieren, ist an die Innenseite der Grundplatte 5 und Stützwand 17 eine Barrierefolie 19 angelegt.In the vertical section of Fig. 3 can be seen further that the bottom of Ausgiesstubus 3 is closed in the originality state of a support wall 17. This is connected via a weakening zone 18 with the base body 1. A cutting element (not shown) cuts the weakened zone 18 when the screw cap 2 is turned off for the first time, thereby exposing the passage of the pouring tube 3 for pouring. To get a sufficient To guarantee durability and aroma protection of the filled product, a barrier film 19 is applied to the inside of the base plate 5 and support wall 17.
