Description

Die Erfindung betrifft ein wiederverschließbares Ausgießelement für in Karton/Kunststoff-Verbundpackungen abgefüllte flüssige Lebensmittel, bestehend aus einem einen umlaufenden Flansch und sowohl ein stabil ausgeführtes Innengewinde als auch ein Außengewinde aufweisenden Grundkörper, einem wenigstens eine Schneide od. dgl. aufweisenden Öffnungselement und einem als Gewindekappe ausgeführten Schraubdeckel, wobei das Öffnungselement ein stabil ausgeführtes Außengewinde aufweist und im Inneren des Grundkörpers angeordnet ist und wobei das Öffnungselement so ausgebildet ist, dass es beim erstmaligen Betätigen des Schraubdeckels eine Öffnung in das unter dem Ausgießelement befindliche Packungsmaterial schneidet.The invention relates to a resealable pouring element for filled in cardboard / plastic composite packaging liquid food, consisting of a circumferential flange and both a stable running internal thread and an external thread having basic body, od at least one cutting od. Like. Opening element and a threaded cap executed screw cap, wherein the opening element has a stably executed external thread and is arranged in the interior of the base body and wherein the opening element is formed so that it intersects the first time pressing the screw an opening in the packaging material located under the spout.

Wiederverschließbare Ausgießelemente für in Karton/Kunststoff-Verbundpackungen abgefüllte flüssige Lebensmittel sind aus der Praxis in vielerlei Ausführungen bekannt. Sie dienen einerseits zum erstmaligen Öffnen der Packungen und sind in der hier interessierenden Ausbildung von außen auf die bereits gefüllte und verschlossene Verpackung aufgebracht. Häufig weist dazu das Verpackungsmaterial im Bereich der - späteren - Ausgießöffnung eine Schwächungszone auf. Diese kann entweder als eine Perforation des Materials ausgebildet sein oder aber als eine Gießöffnung im Trägermaterial (Karton), welche beim Laminieren der inneren und äußeren Kunststoffschichten mit Kunststoff, meist Polyethylen, überspannt wird.Reclosable pouring elements for liquid foodstuffs filled in cardboard / plastic composite packages are known in practice in many designs. They serve on the one hand for the first time to open the packages and are applied in the education of interest from the outside to the already filled and sealed packaging. Frequently, the packaging material has a weakening zone in the region of the - later - pouring opening. This can either be formed as a perforation of the material or as a pouring opening in Carrier material (cardboard), which is covered with plastic, usually polyethylene, during lamination of the inner and outer plastic layers.

In jedem Fall ist es notwendig, dass zum erstmaligen Öffnen eine vom Benutzer aufgebrachte Schneidkraft so in einen Öffnungsvorgang umgesetzt wird, dass ein zuverlässiges Öffnen einer ausreichend großen Gießöffnung gewährleistet ist. Neben Ausgießelementen mit schwenkbaren Öffnungselementen haben sich insbesondere solche Ausgießelemente bewährt, die mit einem Schraubverschluss als Deckel versehen sind und wobei das erstmalige Abdrehen des Schraubverschlusses ein entsprechendes Eindrehen eines ringartig ausgebildeten Öffnungselementes in das Packungsmaterial bewirkt.In any case, it is necessary that, for the first time opening, a cutting force applied by the user is converted into an opening operation in such a way that reliable opening of a sufficiently large pouring opening is ensured. In addition to pouring elements with pivotable opening elements, in particular those pouring elements have been proven which are provided with a screw cap as a lid and wherein the first-time twisting of the screw cap causes a corresponding screwing an annular opening element into the packing material.

Ein solches gattungsgemäßes Ausgießelement ist aus der EP 1 088 764 A1 vorbekannt. Es besteht aus einem einen umlaufenden Befestigungsflansch aufweisenden Grundkörper, einem darin angeordneten hohlzylinderförmigen Öffnungselement und einem Schraubdeckel, wobei die drei Einzelteile so aufeinander abgestimmt sind, dass beim erstmaligen Öffnen des Ausgießelementes mittels einer formschlüssigen Verbindung zwischen Schraubdeckel und Öffnungselement eine helixartige Bewegung des Öffnungselements und damit ein Herstellen einer Gießöffnung bewirkt. Solche dreiteiligen Ausgießelemente erfordern bei ihrer Montage teilweise einen nicht unerheblichen Aufwand. Es hat sich gezeigt, dass das bekannte Ausgießelement neben seiner aufwendigen Montage nicht beliebig klein ausgebildet werden kann, beispielsweise, um mit entsprechend kleinen Packungsgrößen wie 0,2 oder 0,25 1 verwendet zu werden. Da solche kleine Packungsformate einen relativ schmalen Kopfbereich aufweisen, ist es bei der Packungsfertigung nicht mehr möglich, mit überbeschichteten Gießöffnungen zu arbeiten. Das bekannte dreiteilige Ausgießelement ist jedoch nur zum Öffnen einer überbeschichteten Gießöffnung in der Lage.Such a generic pouring is known from EP 1 088 764 A1 previously known. It consists of a circumferential mounting flange having a base body, a hollow cylindrical opening member and a screw cap, wherein the three individual parts are coordinated so that the first time the pouring element by means of a positive connection between the screw and opening element a helical movement of the opening element and thus a Producing a pouring opening causes. Such three-part pouring elements require in their installation partially a considerable effort. It has been shown that the known pouring element can not be made arbitrarily small in addition to its complex assembly, for example, to be used with correspondingly small pack sizes such as 0.2 or 0.25 1. Because such small package formats a relatively narrow Head area, it is no longer possible in the packaging production to work with over-coated pouring openings. However, the known three-part pouring element is only capable of opening an over-coated pouring opening.

Aus der EP 1 262 412 A1 ist ein Ausgießelement bekannt, bei dem in der Wandung des Öffnungselementes Öffnungen vorgesehen sind, in deren Bereich das Außengewinde des Öffnungselementes unterbrochen ist. Hierbei handelt es sich jedoch um eine "Zwangs-Unterbrechung", die mit einer erleichterten Montage nichts gemein hat.From the EP 1 262 412 A1 a pouring element is known, in which openings are provided in the wall of the opening element, in the region of which the external thread of the opening element is interrupted. However, this is a "forced interruption", which has nothing in common with a simplified installation.

Ein anderes Ausgießelement ist aus der EP 1 571 0 95 A1 bekannt. Auch hier sind im Öffnungselement Öffnungen vorhanden, welche als Verhakungselemente für einen im Ausgießelement vorhandenen Wirkstoff dienen. Es ist klar, dass auch hier im Bereich der Öffnungen die Gewindeabschnitte unterbrochen sind, jedoch wiederum zwangsweise bedingt und nicht zur Erleichterung der Montage der Einzelteile.Another pouring element is from the EP 1 571 0 95 A1 known. Again, openings are provided in the opening element, which serve as Verhakungselemente for an active ingredient present in the pouring. It is clear that here too in the area of the openings, the threaded sections are interrupted, but again forcibly conditioned and not to facilitate the assembly of the items.

Die WO 03/101843 A1 beschreibt ein dreiteiliges Ausgießelement, bei dem jedoch das Öffnungselement nicht schraubend bewegt wird. Der eigentliche Öffnungsvorgang geschieht hier durch eine Kombination einer Stech- mit einer Drehbewegung, also einer Überlagerung von einer axialen und einer radialen Bewegung.The WO 03/101843 A1 describes a three-part pouring element, in which, however, the opening element is not moved by screwing. The actual opening process is done here by a combination of a piercing with a rotational movement, ie a superposition of an axial and a radial movement.

Der Erfindung liegt daher die Aufgabe zugrunde, das eingangs erwähnte und zuvor näher beschriebene Ausgießelement so auszugestalten und weiterzubilden, dass es bei einer möglichst einfachen Montage geeignet ist, das Verbundmaterial einer Getränkepackung auch ohne vorherige Schwächung zuverlässig zu durchtrennen und eine ausreichend große Gießöffnung herzustellen.The invention is therefore based on the object, the above-mentioned and previously described in detail pouring element and further develop that it is suitable for the simplest possible mounting, to reliably sever the composite material of a beverage pack without weakening and to produce a sufficiently large pouring opening.

Gelöst wird diese Aufgabe bei einem Ausgießelement nach dem Oberbegriff von Anspruch 1 dadurch, dass das Außengewinde des Öffnungselements im unteren Abschnitt wenigstens in einem Bereich derart reduziert oder unterbrochen ist und dass das Innengewinde des Grundkörpers wenigstens in einem entsprechenden Bereich ebenso reduziert oder unterbrochen ist, damit bei der Erstmontage das Öffnungselement ohne Einschrauben, Einpressen oder Überpressen der Gewinde axial von oben in den Grundkörper hinein bewegt werden kann.This object is achieved in a pouring element according to the preamble of claim 1, characterized in that the external thread of the opening member in the lower portion is at least reduced or interrupted in one area and that the internal thread of the body is also reduced or interrupted at least in a corresponding area, so can be moved axially from above into the main body during initial assembly, the opening element without screwing, press-fitting or over-pressing of the thread.

Die Erfindung hat erkannt, dass es möglich ist, den Zusammenbau von Öffnungselement und Grundkörper ohne Einpressen und Überpressen der Gewinde zu realisieren. Durch die entsprechenden Reduzierungen bzw. Unterbrechungen ist es nicht mehr notwendig, das Öffnungselement bei der Erstmontage in den Grundkörper einzuschrauben. Durch die aufeinander abgestimmten Gewindeabschnitte des erfindungsgemäßen Ausgießelementes ist erreicht worden, dass zunächst das Öffnungselement - entsprechend radial ausgerichtet - axial von oben in den Grundkörper hineinbewegt wird und dass gleichzeitig oder anschließend der Schraubdeckel montiert werden kann. Auf ein zeitaufwendiges Einschrauben des Öffnungselementes in den Grundkörper kann vollständig verzichtet werden. Durch das bajonetteartige Eingreifen des Gewindes beim erstmaligen Betätigen des Schraubdeckels wird das Öffnungselement gedreht und bereits nach kurzer Drehung bewirkt der Formschluss der aufeinander abgestimmten Gewinde ein helixartiges Eindringen der Schneide des Öffnungselementes in das Packungsmaterial.The invention has recognized that it is possible to realize the assembly of opening element and body without pressing in and over-pressing of the thread. Due to the corresponding reductions or interruptions, it is no longer necessary to screw the opening element in the initial assembly in the body. Due to the coordinated threaded sections of the pouring element according to the invention has been achieved that initially the opening element - radially aligned accordingly - axially moved from above into the body and that at the same time or subsequently the screw cap can be mounted. On a time-consuming screwing the opening element in the body can be completely eliminated. By the bayonet-like engagement of the thread when first operating the screw cap, the opening element is rotated and after a short rotation causes the positive connection of the coordinated Thread a helical penetration of the cutting edge of the opening element in the packing material.

Gemäß einer weiteren Lehre der Erfindung ist vorgesehen, dass das Außengewinde des Öffnungselementes an zwei gegenüberliegenden Bereichen reduziert oder unterbrochen ist. Auf diese Weise ist eine sehr gute Kräfteverteilung möglich, da das Öffnungselement im Inneren des Grundkörpers zuverlässig geführt wird. Zweckmäßigerweise weist auch der Grundkörper in seinem Inneren zwei diametral gegenüberliegende Gewindeabschnitte auf.According to a further teaching of the invention, it is provided that the external thread of the opening element is reduced or interrupted at two opposite regions. In this way, a very good distribution of forces is possible because the opening element is guided reliably inside the body. Expediently, the main body also has two diametrically opposite threaded sections in its interior.

Eine andere Ausgestaltung der Erfindung sieht vor, dass das Außengewinde des Öffnungselementes zwei ineinandergreifende Gewindegänge aufweist. Diese Ausführung erlaubt eine relativ steile Ausbildung der Gewindegänge, so dass eine ausreichend große Kraft zum erstmaligen Einschneiden in das Packungsmaterial auf die Schneide des Öffnungselementes aufgebracht werden kann. Besonders bevorzugt umspannt jeder Gewindegang das Öffnungselement wenigstens um 540° (1 ½ mal), so dass das Öffnungselement beim erstmaligen Aufschrauben des Schraubdeckels mehr als 360° gedreht werden kann.Another embodiment of the invention provides that the external thread of the opening element has two intermeshing threads. This embodiment allows a relatively steep formation of the threads, so that a sufficiently large force for the first time cutting into the packing material can be applied to the cutting edge of the opening element. Particularly preferably, each thread spans the opening element at least by 540 ° (1 ½ times), so that the opening element can be rotated more than 360 ° when first screwing the screw cap.

Nach einer weiteren Lehre der Erfindung ist das Außengewinde des Öffnungselements jeweils im unteren Gewindegang reduziert oder unterbrochen. Auf diese Weise wird erreicht, dass bereits nach einer kurzen Drehung des Schraubdeckels und damit des Öffnungselements ein Eingriff an vier unterschiedlichen Stellen der Gewinde stattfindet, so dass die notwendige Stech- und Schneidkraft aufgebracht werden kann.According to another teaching of the invention, the external thread of the opening element is reduced or interrupted respectively in the lower thread. In this way it is achieved that takes place after a short rotation of the screw and thus the opening element engagement at four different points of the thread, so that the necessary piercing and cutting force can be applied.

Darüber hinaus sieht eine weitere Ausgestaltung der Erfindung vor., dass die wenigstens eine Schneide sowohl zum Einstechen in das Karton/Kunststoff-Verbundmaterial als auch zum Aufschneiden einer Gießöffnung geeignet ist. Bevorzugt ist die Schneide so ausgebildet, dass beim Hineindrehen ins Packungsmaterial die Schnittlänge zum Bilden der Gießöffnung kleiner ist als ein Vollkreis.In addition, a further embodiment of the invention provides that the at least one cutting edge is suitable both for piercing into the cardboard / plastic composite material and for cutting a pouring opening. Preferably, the cutting edge is formed so that when screwing into the packing material, the cutting length for forming the pouring opening is smaller than a full circle.

Durch eine entsprechend ausgeformte Schneide wird das herausgetrennte Packungsverbundstück nicht vollkommen vom übrigen Verbundmaterial abgelöst, sondern seitlich nach innen geschwenkt und dort durch das tubusartig in das Packungsinnere hineinragende Öffnungselement fixiert, so dass der gesamte lichte Querschnitt des Öffnungselements als Gießöffnung zur Verfügung steht. Es lässt sich entweder durch eine axiale Länge der Schneide realisieren, welche geringer ist als die axiale Länge eines Gewindeganges oder aber durch eine entsprechend nach innen gebogene Schneide, so dass der Radius des herausgetrennten Verbundmaterialstückes nicht gleich groß ist, sondern sich langsam vergrößert.By a suitably shaped cutting the herauskommennte Packungsverbundstück is not completely detached from the rest of the composite material, but laterally pivoted inward and fixed there by the tube-like opening into the package interior opening element, so that the entire clear cross section of the opening element is available as a pouring opening. It can be realized either by an axial length of the cutting edge, which is smaller than the axial length of a thread or by a correspondingly inwardly curved cutting edge, so that the radius of the herausgeschennten composite material piece is not the same size, but slowly increases.

Nach einer anderen Ausbildung der Erfindung weist der Grundkörper im Inneren mehrere, jeweils diametral gegenüberliegende, Gewindeabschnitte auf. Die Anordnung dieser Gewindeabschnitte ist so gewählt, dass beim axialen Einsetzen des Öffnungselements die reduzierten oder unterbrochenen Bereiche der Gewindegänge des Öffnungselements an den im Inneren des Grundkörpers angeordneten Gewindeabschnitten vorbeibewegt werden können. Erst durch die Drehung des Öffnungselements mittels der Betätigung des Schraubdeckels greifen das Außengewinde des Öffnungselements und das Innengewinde des Grundkörpers ineinander.According to another embodiment of the invention, the base body in the interior a plurality of diametrically opposite, threaded portions. The arrangement of these threaded portions is chosen so that the axial insertion of the opening element, the reduced or discontinuous portions of the threads of the opening element can be moved past the arranged in the interior of the body threaded portions. Only by the rotation of the opening element by means of the actuation of the screw cap engage the external thread of the opening element and the internal thread of the main body into one another.

Eine weitere Lehre der Erfindung sieht vor, dass im unteren Bereich des Grundkörpers wenigstens ein Endanschlag für das nach unten herausgedrehte Öffnungselement vorgesehen ist. Alternativ kann auch das bzw. jedes Außengewinde des Öffnungselements wenigstens einen Endanschlag aufweisen. Durch diese Endanschläge wird zuverlässig sichergestellt, dass das Öffnungselement nicht in das Packungsinnere gelangen kann.Another teaching of the invention provides that at least one end stop for the downwardly rotated opening element is provided in the lower region of the base body. Alternatively, the or each external thread of the opening element may have at least one end stop. These end stops reliably ensure that the opening element can not get into the package interior.

Zur Bewegung des Öffnungselements im Grundkörper dienen mehrere im Inneren des Öffnungselements verteilt angeordnete Vorsprünge, welche einen hakenförmigen Querschnitt aufweisen. Entsprechend ist der Schraubdeckel so ausgebildet, dass in seinem Inneren wenigstens ein Mitnehmersteg vorgesehen ist, der sich von der Oberseite des Schraubdeckels ausgehend, konzentrisch gebogen nach unten erstreckt und auf diese Weise ratschenartig mit den Vorsprüngen im Inneren des Öffnungselements zusammenwirkt. Dadurch wird erreicht, dass das Öffnungselement jeweils nur beim Abschrauben des Schraubdeckels, also entgegen dem Uhrzeigersinn, gedreht wird. Ein erneutes Zuschrauben des Deckels bewirkt ein Abgleiten des wenigstens einen Mitnehmersteges nach innen, so dass das Öffnungselement in seiner jeweiligen Stellung verharrt.For the movement of the opening element in the base body, a plurality of projections distributed in the interior of the opening element are used, which have a hook-shaped cross section. Accordingly, the screw cap is formed so that in its interior at least one entrainment ridge is provided, starting from the top of the screw starting, concentrically bent downwards and cooperates in this way ratchet-like manner with the projections in the interior of the opening element. This ensures that the opening element in each case only when unscrewing the screw, so counterclockwise, is rotated. A renewed screwing of the cover causes the at least one entraining web to slide inwards, so that the opening element remains in its respective position.

Schließlich ist nach einer weiteren Lehre der Erfindung vorgesehen, dass der Schraubdeckel in montierter Stellung über als Sollbruchstellen dienende Materialbrücken mit dem Grundkörper verbunden ist. Dabei verlaufen die Materialbrücken bevorzugt zwischen dem Schraubdeckel und einer Montageplatte, die mit dem Flansch des Grundkörpers verbunden ist.Finally, it is provided according to a further teaching of the invention that the screw cap is connected in the mounted position via serving as predetermined breaking points material bridges with the body. In this case, the material bridges preferably extend between the screw cap and a mounting plate which is connected to the flange of the base body.

Als Material für das Öffnungselement wird ein Material mit einer ausreichenden Härte verwendet, um die Schneide so scharf ausbilden zu können, dass eine Gießöffnung in das - ungeschwächte - Verbundmaterial geschnitten werden kann.The material used for the opening element is a material having sufficient hardness to be able to form the cutting edge so sharply that a pouring opening can be cut into the non-weakened composite material.

Die Erfindung wird nachfolgend anhand einer lediglich ein bevorzugtes Ausführungsbeispiel darstellenden Zeichnung näher erläutert. In der Zeichnung zeigen:

In Fig. 1 ist das erfindungsgemäße Ausgießelement als Explosionszeichnung dargestellt. Es besteht im wesentlichen aus drei verschiedenen Teilen, nämlich einem Grundkörper 1, einem hohlzylinderförmigen Öffnungselement 2 und einem Schraubdeckel 3. Der Grundkörper 1 weist einen umlaufenden Flansch 4 und ein Innengewinde 5 auf, das später noch näher beschrieben wird.In Fig. 1 the pouring element according to the invention is shown as an exploded view. It consists essentially of three different parts, namely a base body 1, a hollow cylindrical opening element 2 and a screw cap 3. The main body 1 has a circumferential flange 4 and an internal thread 5, which will be described later in more detail.

Das Öffnungselement 2 verfügt in seinem Inneren über zwei diametral angeordnete hakenartige Vorsprünge 7, über die die zum Öffnen notwendige Drehkraft vom Schraubdeckel 3 auf das Öffnungselement 2 übertragen wird. Auf seiner äußeren Mantelfläche ist das Öffnungselement 2 mit einem Außengewinde 8 versehen, auf das gleichfalls noch näher eingegangen werden wird.The opening element 2 has in its interior two diametrically arranged hook-like projections 7, via which the rotational force necessary for opening is transmitted from the screw cap 3 to the opening element 2. On its outer surface, the opening element 2 is provided with an external thread 8, which will also be discussed in more detail.

Erfindungsgemäß ist nun das Außengewinde 8 im unteren Abschnitt reduziert, wie Fig. 1 deutlich entnommen werden kann. Bevorzugt befinden sich die reduzierten Bereiche des Außengewindes 8 an zwei diametral gegenüberliegenden Bereichen 8F des Öffnungselements 2.According to the invention, the external thread 8 is now reduced in the lower portion, as Fig. 1 can be clearly taken. The reduced regions of the external thread 8 are preferably located on two diametrically opposite regions 8F of the opening element 2.

Am oberen Ende des Außengewindes 8, das im bevorzugten Ausführungsbeispiel aus zwei jeweils 180° versetzt ineinandergreifenden Gewindegängen 8A und 8B besteht, befindet sich jeweils ein Endanschlag 9, der dafür sorgt, dass das in das Packungsinnere hineingeschraubte Öffnungselement 2 nicht aus dem Grundkörper 1 herausfallen und ins Packungsinnere gelangen kann.At the upper end of the external thread 8, which consists in the preferred embodiment of two mutually 180 ° intermeshing threads 8A and 8B, there is in each case an end stop 9, which ensures that the opening element 2 screwed into the interior of the package can not fall out of the main body 1 and enter the package interior.

Ferner weist das Öffnungselement 2 an seinem unteren Ende eine Schneide 10 auf, wie besonders deutlich aus Fig. 4 zu entnehmen ist.Furthermore, the opening element 2 has a cutting edge 10 at its lower end, as is particularly clear Fig. 4 can be seen.

In Fig. 2 ist das erfindungsgemäße Ausgießelement perspektivisch in fertig montierter Stellung dargestellt. Es ist deutlich erkennbar, dass der Schraubdeckel 3 einstückig mit einer Montageplatte 11 verbunden ist, welche mit dem Grundkörper 1 form- oder kraftschlüssig in Verbindung steht.In Fig. 2 the pouring element according to the invention is shown in perspective in the fully assembled position. It can be clearly seen that the screw cap 3 is integrally connected to a mounting plate 11 which is positively or non-positively connected to the base body 1.

Fig. 3 zeigt das Ausgießelement in gleicher Perspektive nach dem erstmaligen Abschrauben des Schraubdeckels 3. Beim Öffnen reißen Sollbruchstellen in den die Montageplatte 11 und den Schraubdeckel 3 verbindenden Materialbrücken 12, im dargestellten und insoweit bevorzugten Ausführungsbeispiel weist das Ausgießelement drei solche Materialbrücken 12 auf, wobei die zerstörten Materialbrücken 12' in Fig. 3 erkennbar sind. Fig. 3 When opening break predetermined breaking points in the mounting plate 11 and the screw 3 connecting material bridges 12, in the illustrated and insofar preferred embodiment, the pouring three such material bridges 12, wherein the destroyed material bridges 12 'in Fig. 3 are recognizable.

In Fig. 4 ist erkennbar, dass die Montageplatte 11 mit dem Flansch 4 des Grundkörpers 1 bevorzugt formschlüssig verbunden ist. Dazu sind im Flansch 4 zwei sich nach unten aufweitende Öffnungen 13 vorgesehen, in die zwei von der Montageplatte 11 nach unten ausgehende Verbindungszapfen 14 (vgl. Fig. 1) eingreifen und dort verstemmt werden, wie mit 14' angedeutet.In Fig. 4 It can be seen that the mounting plate 11 is preferably positively connected to the flange 4 of the base body 1. For this purpose, two downwardly widening openings 13 are provided in the flange 4, in the two of the mounting plate 11 downwardly outgoing connecting pin 14 (see. Fig. 1 ) and caulked there, as indicated at 14 '.

Aus Fig. 4 geht ferner hervor, dass der Schraubdeckel 3 in seinem Inneren mit zwei konzentrischen Mitnehmerstegen 15 versehen ist, welche vom Deckel des Schraubdeckels 3 nach unten ragen und durch ihre gebogene konzentrische Stegform verwindungssteif Drehkräfte übertragen können, jedoch radial nach innen ausweichen können. Durch diese Ausgestaltung im Zusammenhang mit der hakenförmigen Ausgestaltung der Vorsprünge 7 im Inneren des Öffnungselements 2 wird erreicht, dass beim erstmaligen Öffnen das Öffnungselement mit seiner Schneide 10 eine Öffnung in das unterhalb des Ausgießelementes befindliche Packungsmaterial schneidet. Jedoch werden beim Verschließen des Schraubdeckels 3 die Mitnehmerstege 15 durch die entsprechenden Schrägen der Vorsprünge 7 nach innen abgelenkt, so dass das Öffnungselement 2 nicht verdreht wird.Out Fig. 4 also shows that the screw cap 3 is provided in its interior with two concentric Mitnehmerstegen 15, which protrude from the lid of the screw 3 down and can transmit torsionally stiff rotational forces by their curved concentric web shape, but can dodge radially inward. As a result of this configuration in connection with the hook-shaped configuration of the projections 7 in the interior of the opening element 2, the opening element with its cutting edge 10 intersects an opening in the packing material located below the pouring element when it is first opened. However, when closing the screw cap 3, the driving webs 15 are deflected inwards by the corresponding bevels of the projections 7, so that the opening element 2 is not twisted.

Fig. 5 zeigt nun das Öffnungselement 2 in seiner. Endstellung, da beim abermaligen Öffnen die Mitnehmerstege 15 durch ihre Länge jedoch wiederum hinter die hakenartigen Vorsprünge 7 greifen und bewirken, dass sich das Öffnungselement 2 noch etwas weiter in das Verpackungsmaterial hineinschraubt als in der in Fig. 4 gezeigten Position nach der Erstöffnung. Hier hat das Öffnungselement 2 also noch einmal eine etwa 180°-Drehung vollzogen. Fig. 5 now shows the opening element 2 in his. End position, as the Mitnehmerigenge 15 but again engage behind the hook-like projections 7 during repeated opening and cause the opening element 2 still further screwed into the packaging material than in the in Fig. 4 shown position after the first opening. Here, the opening element 2 has therefore again made an approximately 180 ° rotation.

In den Fig. 6 und 7 ist nun die Funktionsweise des Öffnens durch Schnittdarstellungen näher erläutert. In Fig. 6 ist erkennbar, dass auch der Grundkörper 1 in seinem Inneren am Ende des unteren Gewindeabschnitts 5B ebenfalls einen Endanschlag 16 aufweist, der mit den Endanschlägen 9 des Öffnungselements zusammenwirkt, wie in Fig. 7 ersichtlich. Auf diese Weise wird zuverlässig gewährleistet, dass sich das vom Schraubdeckel 3 betätigte Öffnungselement 2 nicht vom Ausgießelement lösen und ins Packungsinnere fallen kann. Vielmehr verbleibt es in der Endstellung, wobei das von der Schneide 10 gebildete, jedoch nicht vollständig abgetrennte Verbundmaterialstück senkrecht nach unten abgewinkelt wird, so dass der vollständige lichte Querschnitt des Öffnungselements 2 zum Ausgießen zur Verfügung steht.In the Fig. 6 and 7 now the operation of the opening by sectional views is explained in more detail. In Fig. 6 It can be seen that also the base body 1 in its interior at the end of the lower threaded portion 5B also has an end stop 16 which cooperates with the end stops 9 of the opening element, as in Fig. 7 seen. That way it will be reliable ensures that the opening element 2 actuated by the screw cap 3 can not be released from the pouring element and fall into the package interior. Rather, it remains in the end position, wherein the composite material piece formed by the cutting edge 10, but not completely separated, is angled vertically downwards, so that the complete clear cross-section of the opening element 2 is available for pouring.
