Definitions
- the invention relates to a resealable pouring element for cardboard/plastic composite packs, in particular beverage packs, with a base element having a circumferential fastening flange and an external thread, with opening means arranged inside the base element at least in the unopened state of the pouring element and a screw cap with an internal thread, underneath the screw cap an anchor ring is arranged which is non-rotatably connected to the base element and is freely rotatable radially around the base element and is connected to the base element in a tension-resistant manner in the axial direction, so that for secure connection of the screw cap to the base element even in the unscrewed state, the anchor ring is connected via a hinge element, the pivot axis of which is tangential to the base element Outer circumference of the screw cap is aligned, is articulated to the screw cap.
- a pouring element is from the applicant DE 10 2006 016 113 B3 known.
- the screw cap is moved over the cutting element protruding from the pouring element and, together with it, pressed (bounced) onto the base element.
- a plate is integrally molded onto the screw cap and is connected to the screw cap via connecting bridges.
- the plate has pins on its underside, which engage in corresponding recesses in the flange of the base element and are caulked from below after assembly. The connecting bridges break when the pouring element is opened for the first time, so that the screw cap is then only loosely attached to the pouring element and the composite pack.
- the US 2012/0181281 A1 shows a pouring element in which the screw cap is connected in the unopened state via connecting bridges to a plate attached to the circumferential flange of the base element. When opened for the first time, the connecting bridges are separated so that the screw cap is no longer connected to the base element.
- EP 1 124 734 B1 is a closure device for a PET bottle with a ring arranged under the screw cap, which is connected to the screw cap via a film hinge and prevents the screw cap from being pulled off even in the open state.
- the US 5,215,204 A shows a closure cap for a bottle with a ring arranged under the screw cap, which is materially connected to the screw cap via two connecting bridges.
- the ring and the bottle are designed in such a way that the ring cannot be removed from the bottle.
- the screw cap for a conventional bottle.
- the screw cap consists of one Screw lid and a ring connected via a film hinge.
- the ring ensures that the screw cap is securely connected to the bottle in the axial direction.
- a generic pouring element in which an anchor ring which is connected to it in a rotationally fixed manner is arranged below the screw lid.
- the anchor ring and the screw cap are connected to one another via a connecting element, which has two elements in the middle that form a hinge axis.
- a pouring element in which a closure cap is connected to the base element of the pouring element via an anchor ring connected to the closure cap, even in the open state.
- the anchor ring is connected to the base element in such a way that it cannot move upwards in the axial direction when the pouring element is opened.
- the present invention is based on the object of designing and developing a resealable pouring element for cardboard/plastic composite packs of the type mentioned in such a way that a connection of the screw cap to the pouring element is ensured even when unscrewed.
- a tensile connection is provided between the screw cap and the pouring element, in which the screw cap cannot be detached from the pouring element in the axial direction with a force of at least 10 to 30 N, which is usually necessary for opening a commercially available screw cap for the first time.
- a radial adjustment of the screw cap in the locked open position is particularly advantageous in order to allow pouring out to enable any direction of the pouring element, since composite packs are not essentially rotationally symmetrical like commercially available PET bottles or have a substantially square cross-section and can be poured equally well from every side. Furthermore, it is desirable that in the locked open position there is as much free space as possible in front of the pouring opening, despite the opening means that are often present in the screw cap of cardboard/plastic composite packages and are necessary for producing a pouring opening.
- the opening means are designed such that when the composite pack is first opened when the screw cap is screwed on, a pouring opening is created within the pack by breaking open the composite material of the pack or a barrier layer located in the base element
- Pouring element is created that the base element has an outwardly projecting and essentially circumferential collar on its outside, that the anchor ring has at its lower end a substantially circumferential web directed towards the base element, which is arranged below the collar in order to prevent the Anchor ring over the collar to prevent the collar from being arranged in the axial direction in the upper region of the anchor ring in the unopened state, so that when the screw cover is unscrewed, movement of the hinge element in the axial direction is possible until the web comes into contact with the collar, and that the pivot axis of the hinge element is arranged in the axial direction in the upper half of the base element when the screw cover is pivoted away.
- the axially tensile connection of the screw cap to the base element ensures that the screw cap does not represent a loose plastic part even when the pouring element is open and that it cannot enter the environment as a loose plastic part.
- the invention thus makes a valuable contribution to reducing environmental pollution.
- the film hinges that are usually used to connect a screw cap to a base element often tear off after just a small number of opening processes and therefore cannot ensure a secure connection of a screw cap to its base element.
- the special design of the hinge element ensures that the screw cap does not become detached from the rest of the base element even after the pouring element has been opened several times.
- the anchor ring By providing a substantially circumferential web directed towards the base element at the lower end of the anchor ring, which is arranged below the collar, the anchor ring is reliably prevented from being pulled off over the collar.
- At least either the collar or the web can also be interrupted at one or more points, provided that it is ensured that the anchor ring, with its web directed towards the base element, cannot slip over the collar provided on the base element.
- the anchor ring including the hinge element can cover the greatest possible distance upwards when the screw cap is screwed on and pivoted open, so that the pivot axis of the hinge element is offset upwards.
- a pivot axis arranged as high as possible is desirable in order to enable the largest possible opening angle of the screw cap for comfortable pouring despite the bottle neck that is not present on composite packs.
- the anchor ring has a slot running in the circumferential direction, which separates the anchor ring in a section into upper parts and a lower part, the upper parts and the lower part being arranged at a distance from one another in the axial direction. It is advantageous if the slot is in the circumferential direction in the area of the hinge element is arranged.
- the hinge element can be connected to the upper parts of the anchor ring in such a way that the end of the upper parts facing the hinge element is twisted after the screw cap has been swiveled open.
- the hinge element is arranged centrally to the slot in the circumferential direction. This ensures that the two sides of the upper parts of the anchor ring are loaded evenly when the screw cap is swiveled open.
- a preferred embodiment of the invention provides that the lower end of the hinge element, in the unopened state of the pouring element, projects downwards over the lower end of the upper parts of the anchor ring in the direction of the fastening flange. If the screw cap is swung open after it has been unscrewed, the hinge element folds over with its lower end in the direction of the slot, so that at an opening angle of 120° to 150° the screw cap is locked in its open position with respect to its swiveling open. In this state, the screw cap can no longer swing back without applying external force. This has the great advantage that the screw cap does not automatically swing back when pouring and does not come into contact with the product during the pouring process.
- the screw cap can be freely rotated radially in its locked open position. This has the great advantage that the screw cap can be turned into a position desired by the user. In the locked position, a slight force must still be applied from the outside in order to enable rotation, since the fixation of the screw cap with respect to its swinging open creates an increased frictional resistance between the hinge element and the base element. However, the increased frictional resistance is also desirable so that the screw cap does not easily move in the direction of the pouring jet when pouring, caused by the gravitational force.
- a further teaching of the invention provides that the hinge element is arranged above the lower third of the base element with respect to its pivot axis in the unopened state. Arranging the hinge element above the lower third ensures that the screw cap can achieve an open position with an opening angle of 120° to 150° before the screw cap hits the composite pack. Since composite packs typically do not have a bottle neck like PET bottles, the swing-open movement of the screw cap is significantly more limited than with PET bottles. In order to achieve a sufficiently large opening angle for a pleasant pouring process, it is desirable to arrange the hinge element as high as possible.
- the pivot axis of the hinge element is arranged in the axial direction in the upper third of the base element when the screw cover is pivoted away.
- the opening means comprise a cutting element arranged in the interior of the base element and at least one driver web arranged in the interior of the screw cap and connected to it in a form-fitting or material-locking manner, which is preferably attached as close as possible to the hinge element in the circumferential direction.
- the hinge element can be locked in the external thread of the flange in order to keep the screw cap open.
- the driving bar is also possible to arrange the driving bar as far away from the hinge element as possible in the circumferential direction. This is useful if the hinge elements should not be in the way when the screw cap is opened/tilted away. This enables clean opening/tilting away without the hinge element and the upper edge of the pouring spout getting caught.
- a plurality of driver webs arranged evenly distributed over the circumference are provided.
- This driving bar can at least partially protrude from the inside of the screw cap when swiveled open. It is therefore particularly important that a sufficiently large opening angle of the screw cap can be achieved.
- the pouring element according to the invention preferably has at least one originality seal between the fastening flange and the anchor ring or the screw cap.
- This can consist of a band, one end of which is firmly connected to the anchor ring and in which the other end is connected to the anchor ring by means of a predetermined breaking point in such a way that the predetermined breaking point of at least one mandrel element arranged on the fastening flange When the screw cap is unscrewed, it is broken open and the consumer is informed that the first opening has already taken place.
- a further ring is arranged below the anchor ring, which is connected to the anchor ring via a plurality of material bridges and serves as a seal of originality.
- the screw cap, the anchor ring and the additional ring that serves as a seal of authenticity are made in one piece.
- the ring can only be rotated to a limited extent by blocking webs projecting inwards from the ring with locking elements arranged over the circumference of the base element, so that when the screw cap is unscrewed for the first time, it is detached from the anchor ring by tearing off the material bridges and remains in its position on the base element.
- a further embodiment of the invention provides that the base element has an outwardly projecting and essentially circumferential collar on its outside, the clear inside diameter of the collar being smaller as the clear distance between the oppositely arranged webs of the ring.
- a further advantageous teaching of the invention provides that the fastening flange of the pouring element is connected to the inside of the composite pack.
- a corresponding composite pack has a material recess at the location of the later pouring opening.
- the pouring element is guided through the interior of the composite pack, positioned in the area of the material recess and then connected to the inside of the composite pack.
- the interior of the base element is closed on the pack side in the unopened state, so that the product in the composite pack cannot flow into the pouring element in the unopened state.
- opening means include an opening element which is arranged in the interior of the base element in the unopened state and is materially connected to it, and at least one force transmission element which is arranged inside the screw cap and is materially connected to it.
- the opening element is positively connected to the at least one force transmission element and is separated from the base element at predetermined breaking points when the pouring element is opened for the first time, triggered by the rotation of the at least one force transmission element, so that there is no longer a material connection between the base element and the opening element. From this point on, the opening element is only positively connected to the at least one force transmission element, so that it cannot get into the composite pack present under the pouring element. When swiveled open, the opening element can at least partially protrude from the interior of the screw cap. Corresponding opening means are already available JP 5857668 B2 known.
- the drawing shows a preferred embodiment of a pouring element according to the invention to show its functionality when opening a Composite packaging to make it clear.
- Fig. 1 A pouring element according to the invention without a composite pack is shown in a perspective view.
- the pouring element has a base element 2 having a circumferential fastening flange 1 (which in Fig. 1 is not visible) and a screw cap 3, which is used for the initial opening and re-closing of a composite pack, not shown.
- an anchor ring 4 connected to it in a rotationally fixed manner in order to reliably exclude removal of the screw cap 3 from the base element 2 or a composite pack provided with it.
- the screw cap 3 and the anchor ring 4 are connected to one another in an articulated manner via a hinge element 5, the pivot axis of which is aligned tangentially to the outer circumference of the screw cap 3.
- the anchor ring 4 has a circumferentially extending slot 6, which separates the anchor ring 4 in a section into upper parts 4A and a lower part 4B, the upper parts 4A and the lower part 4B being arranged at a distance from one another in the axial direction.
- the hinge element 5 can be designed with a greater, the same or even smaller wall thickness compared to the rest of the screw cap 2.
- Fig. 2 It can be clearly seen that the slot 6 is arranged centrally in the circumferential direction of the hinge element 5.
- the hinge element 5 is connected to the upper parts 4A of the anchor ring 4 and is arranged above the lower third of the base element 2 with respect to its pivot axis in the unopened state.
- Fig. 2 shows that the lower end of the hinge element 5 in the unopened state of the pouring element protrudes downwards over the lower end of the upper parts 4A of the anchor ring 4 in the direction of the fastening flange 1.
- ribs 7 which project outwards in the direction of the anchor ring 4 and extend perpendicular to the fastening flange 1 are provided on the lower region of the base element 2. These center the anchor ring 4 with respect to the base element 2 and ensure uniform friction when turning the anchor ring 4.
- Fig. 3 shows the base element 2 of the in Fig. 1 Pouring element shown. It can be seen that the base element 2 has an external thread 8, by means of which the in Fig. 3 Screw cap 3, not shown, can be screwed onto the base element 2.
- the base element 2 also has an outwardly projecting and radially circumferential collar 9 on its outside above the ribs 7.
- a cutting element 10 can be seen inside the base element 2, which creates a pouring opening within the pouring element when the composite pack is opened for the first time by screwing on the screw cap 3.
- Fig. 4 The pouring element is now shown in a vertical section in the unopened state.
- the collar 9 touches the inner surface of the anchor ring 4 with its outer peripheral surface in the upper region of the anchor ring 4.
- the anchor ring 4 has at its lower end a radially circumferential web 11 directed towards the base element 2, which is arranged below the collar 9 provided on the base element 2. This prevents the anchor ring 4 from being pulled off beyond the collar 9.
- the collar 9 is arranged in the unopened state of the pouring element in the upper region of the anchor ring 4, so that when the screw cap 3 is screwed on, the movement of the anchor ring 4 and thus also that of the hinge element 5 in the axial direction is made possible upwards until the web 11 with the collar 9 comes into contact.
- an opening means can be seen, consisting of the cutting element 10 arranged inside the base element 2 and driver webs 12 arranged inside the screw cap 3, which are cohesively connected to it.
- the cutting element 10 which has an external thread 13

- Composite pack conveyed so that a pouring opening is created within the pouring element.
- the driver webs 12 protrude downwards in comparison to the outer peripheral surface of the screw cap 3, so that they protrude from the inside of the screw cap 3 in the swung-open state.
- Fig. 5 to 8 finally illustrate the function of the pouring element according to the invention during the opening process of the screw cap 3.
- Fig. 5 the pouring element is shown at the beginning of the screwing-on process of the screw cap 3.
- the anchor ring 4 is connected to the base element 2 in a radially freely rotatable manner, so that the anchor ring 4 moves with the rotational movement of the screw cap 3.
- Fig. 6 the pouring element is shown with the screw cap 3 already screwed on but still closed.
- the pouring element is shown in a side view, while the right side of the Fig. 6 represents a vertical section.
- the anchor ring 4 and, along with it, the hinge element 5 have also moved upward due to the upward movement of the screw cap 3.
- the collar 9 provided on the base element 2 and the web 11 arranged on the anchor ring touch each other.
- the slot 6 has increased at least in the middle in the axial direction due to the upward movement of the screw cap 3, so that the pivot axis of the hinge element 5 increases in the axial direction Direction has shifted further upwards.
- Fig. 7 the pouring element is shown in an open state and with a screw cap 3 pivoted away with a composite pack.
- the anchor ring 4 cannot slip over the collar 9, so that despite its rotatability with respect to the base element 2 it is connected to the base element 2 in a tensile manner in the axial direction. Consequently, the anchor ring 4 and thus also the screw cap 3 are reliably prevented from being pulled off.
- FIG. 7 shows that by swinging open the screw cover 3, the upper parts 4A of the anchor ring 4 at one end, which establish a connection to the hinge element 5, twist, but do not tear off.
- the hinge element 5 rotates by pivoting the screw cap 3 in the direction of the slot 6 until it is as shown in Fig. 8 shown folds over so that it is locked in its open position at an opening angle of 120 ° to 150 ° with respect to its swing open.
- the screw cap 3 can still be freely rotated radially in its locked open position, although due to increased frictional resistance a certain force must be applied from the outside in order to enable rotation.
- driver webs 12 of the opening means protrude from the inside of the screw cap 3 in the swung-open state.
- a band 15 serving as an originality seal is attached to the anchor ring 4, one end of which is firmly connected to the anchor ring 4 and in which the other end is connected to the anchor ring 4 by means of a predetermined breaking point in such a way that the predetermined breaking point is of one on the Fastening flange 1 arranged mandrel element 16 is broken when the screw cap 3 is screwed on for the first time.

Um sicherzustellen, dass die Schraubdeckel von Verbundpackungen nicht ungewollt in die Umwelt gelangen, ist es erwünscht, Schraubdeckel an ihre jeweilige Verbundpackung sicher anzubinden, so dass lose Plastikteile auch bei geöffneter Packung zuverlässig vermieden werden.In order to ensure that the screw caps of composite packs do not accidentally end up in the environment, it is desirable to securely attach screw caps to their respective composite packs so that loose plastic parts are reliably avoided even when the pack is opened.
Elemente, die eine sichere Anbindung von Schraubdeckeln an ihre jeweilige Packung auch im geöffneten Zustand sicherstellen, sind bereits aus dem Stand der Technik seit längerem im Bereich der Verschlüsse für handelsübliche PET-Flaschen bekannt. Die bekannten PET-Flaschen haben dabei gemein, dass der zylindrische Grundkörper einen Flaschenhals aufweist, der deutlich schmaler als der Grundkörper ist, so dass ein mit einem Anbindungselement versehener Schraubdeckel deutlich über 90° weggeschwenkt werden kann.Elements that ensure a secure connection of screw caps to their respective packaging, even when opened, have been known from the prior art for a long time in the field of closures for commercially available PET bottles. The known PET bottles have in common that the cylindrical base body has a bottle neck that is significantly narrower than the base body, so that a screw cap provided with a connecting element can be pivoted away by well over 90°.

Davon ausgehend liegt der vorliegenden Erfindung die Aufgabe zu Grunde, ein wiederverschließbares Ausgießelement für Karton/Kunststoff-Verbundpackungen der eingangs genannten Art so auszugestalten und weiterzubilden, dass eine Anbindung des Schraubdeckels auch im abgeschraubten Zustand an das Ausgießelement sichergestellt ist. Dazu ist eine zugfeste Verbindung zwischen Schraubdeckel und Ausgießelement vorgesehen, bei der sich der Schraubdeckel mit einer Kraft von mindestens 10 bis 30 N, die üblicherweise für das erstmalige Öffnen eines handelsüblichen Schraubdeckels notwendig ist, in axialer Richtung nicht vom Ausgießelement lösen lässt.Proceeding from this, the present invention is based on the object of designing and developing a resealable pouring element for cardboard/plastic composite packs of the type mentioned in such a way that a connection of the screw cap to the pouring element is ensured even when unscrewed. For this purpose, a tensile connection is provided between the screw cap and the pouring element, in which the screw cap cannot be detached from the pouring element in the axial direction with a force of at least 10 to 30 N, which is usually necessary for opening a commercially available screw cap for the first time.
Ferner ist wünschenswert, dass eine zuverlässige Arretierung des Schraubdeckels in einer Öffnungsstellung mit Bezug auf das Aufschwenken gewährleistet wird, um ein Ausgießen aus der Verbundpackung ohne unerwünschtes Zuschwenken des Schraubdeckels zu ermöglichen. Eine radiale Verstellung des Schraubdeckels in der arretierten Öffnungsstellung ist dabei von besonderem Vorteil, um ein Ausgießen aus jeder Richtung des Ausgießelements zu ermöglichen, da Verbundpackungen nicht wie handelsübliche PET-Flaschen im Wesentlichen rotationssymmetrisch sind oder einen im Wesentlichen quadratischen Querschnitt haben und von jeder Seite aus gleich gut ausgegossen werden können. Weiterhin ist erwünscht, dass in der arretierten Öffnungsstellung trotz der bei Karton/Kunststoff-Verbundpackungen im Schraubdeckel oft vorhandenen Öffnungsmittel, die für das Herstellen einer Gießöffnung notwendig sind, möglichst viel Freiraum vor der Gießöffnung vorhanden ist.Furthermore, it is desirable that a reliable locking of the screw cap in an open position with respect to the swinging open is ensured in order to enable pouring from the composite pack without undesirable pivoting of the screw cap. A radial adjustment of the screw cap in the locked open position is particularly advantageous in order to allow pouring out to enable any direction of the pouring element, since composite packs are not essentially rotationally symmetrical like commercially available PET bottles or have a substantially square cross-section and can be poured equally well from every side. Furthermore, it is desirable that in the locked open position there is as much free space as possible in front of the pouring opening, despite the opening means that are often present in the screw cap of cardboard/plastic composite packages and are necessary for producing a pouring opening.
Diese Aufgabe wird bei einem wiederverschließbaren Ausgießelement mit den Merkmalen des Oberbegriffs von Anspruch 1 dadurch gelöst, dass die Öffnungsmittel so ausgebildet sind, dass bei Erstöffnung der Verbundpackung beim Aufschrauben des Schraubdeckels durch Aufbrechen des Verbundmaterials der Packung oder einer im Basiselement befindlichen Barriereschicht eine Gießöffnung innerhalb des Ausgießelements geschaffen wird, dass das Basiselement auf seiner Außenseite einen nach außen abstehenden und im Wesentlichen umlaufenden Kragen aufweist, dass der Ankerring an seinem unteren Ende einen im Wesentlichen umlaufenden, zum Basiselement gerichteten Steg aufweist, der unterhalb des Kragens angeordnet ist, um ein Abziehen des Ankerrings über den Kragen zu verhindern, dass der Kragen im ungeöffneten Zustand in axialer Richtung im oberen Bereich des Ankerrings angeordnet ist, so dass bei abgeschraubtem Schraubdeckel eine Bewegung des Scharnierelements in axialer Richtung möglich ist, bis der Steg mit dem Kragen in Kontakt tritt, und dass die Schwenkachse des Scharnierelements bei weggeschwenktem Schraubdeckel in axialer Richtung in der oberen Hälfte des Basiselements angeordnet ist.This object is achieved in a resealable pouring element with the features of the preamble of
Durch die in axialer Richtung zugfeste Anbindung des Schraubdeckels an das Basiselement wird sichergestellt, dass der Schraubdeckel auch im geöffneten Zustand des Ausgießelements kein loses Plastikteil darstellt und dieses nicht als loses Plastikteil in die Umwelt gelangen kann. Die Erfindung leistet so einen wertvollen Beitrag zur Reduzierung der Umweltverschmutzung.The axially tensile connection of the screw cap to the base element ensures that the screw cap does not represent a loose plastic part even when the pouring element is open and that it cannot enter the environment as a loose plastic part. The invention thus makes a valuable contribution to reducing environmental pollution.
Die für die Anbindung eines Schraubdeckels an ein Basiselement üblicherweise eingesetzten Filmscharniere reißen oftmals bereits schon nach einer geringen Anzahl von Öffnungsvorgängen ab und können daher keine sichere Anbindung eines Schraubdeckels an sein Basiselement gewährleisten. Durch die besondere Ausgestaltung des Scharnierelements wird sichergestellt, dass auch nach mehrmaligem Öffnen des Ausgießelements der Schraubdeckel sich nicht von dem Rest des Basiselements löst.The film hinges that are usually used to connect a screw cap to a base element often tear off after just a small number of opening processes and therefore cannot ensure a secure connection of a screw cap to its base element. The special design of the hinge element ensures that the screw cap does not become detached from the rest of the base element even after the pouring element has been opened several times.
Durch Vorsehen eines im Wesentlichen umlaufenden, zum Basiselement gerichteten Stegs am unteren Ende des Ankerrings, der unterhalb des Kragens angeordnet ist, wird ein Abziehen des Ankerrings über den Kragen zuverlässig verhindert. Auch kann zumindest entweder der Kragen oder der Steg an einer oder mehreren Stellen unterbrochen sein, sofern gesichert ist, dass der Ankerring mit seinem zum Basiselement gerichteten Steg nicht über den am Basiselement vorgesehenen Kragen rutschen kann.By providing a substantially circumferential web directed towards the base element at the lower end of the anchor ring, which is arranged below the collar, the anchor ring is reliably prevented from being pulled off over the collar. At least either the collar or the web can also be interrupted at one or more points, provided that it is ensured that the anchor ring, with its web directed towards the base element, cannot slip over the collar provided on the base element.
Durch einen möglichst großen Abstand in axialer Richtung zwischen dem Steg und dem Kragen im ungeöffneten Zustand des Ausgießelements kann der Ankerring einschließlich des Scharnierelements beim Aufschrauben und Aufschwenken des Schraubdeckels eine möglichst große Strecke nach oben zurücklegen, so dass die Schwenkachse des Scharnierelements nach oben versetzt wird. Eine möglichst weit oben angeordnete Schwenkachse ist wünschenswert, um trotz des an Verbundpackungen nicht vorhandenen Flaschenhalses einen möglichst großen Öffnungswinkel des Schraubdeckels für ein angenehmes Ausgießen zu ermöglichen.By having the largest possible distance in the axial direction between the web and the collar when the pouring element is in the unopened state, the anchor ring including the hinge element can cover the greatest possible distance upwards when the screw cap is screwed on and pivoted open, so that the pivot axis of the hinge element is offset upwards. A pivot axis arranged as high as possible is desirable in order to enable the largest possible opening angle of the screw cap for comfortable pouring despite the bottle neck that is not present on composite packs.
Eine weitere Lehre der Erfindung sieht vor, dass der Ankerring einen in Umfangsrichtung verlaufenden Schlitz aufweist, der den Ankerring in einem Abschnitt in obere Teile und einen unteren Teil trennt, wobei die oberen Teile und der untere Teil in axialer Richtung beabstandet zueinander angeordnet sind. Dabei ist es vorteilhaft, wenn der Schlitz in Umfangsrichtung im Bereich des Scharnierelements angeordnet ist. So kann das Scharnierelement derart mit den oberen Teilen des Ankerrings verbunden werden, dass jeweils das dem Scharnierelement zugewandte Ende der oberen Teile nach dem Aufschwenken des Schraubdeckels tordiert ist.A further teaching of the invention provides that the anchor ring has a slot running in the circumferential direction, which separates the anchor ring in a section into upper parts and a lower part, the upper parts and the lower part being arranged at a distance from one another in the axial direction. It is advantageous if the slot is in the circumferential direction in the area of the hinge element is arranged. The hinge element can be connected to the upper parts of the anchor ring in such a way that the end of the upper parts facing the hinge element is twisted after the screw cap has been swiveled open.
In einer besonders bevorzugten Ausgestaltung der Erfindung ist das Scharnierelement in Umfangsrichtung mittig zum Schlitz angeordnet. Dies stellt sicher, dass die beiden Seiten der oberen Teile des Ankerrings gleichmäßig bei Aufschwenken des Schraubdeckels belastet werden.In a particularly preferred embodiment of the invention, the hinge element is arranged centrally to the slot in the circumferential direction. This ensures that the two sides of the upper parts of the anchor ring are loaded evenly when the screw cap is swiveled open.
Eine bevorzugte Ausbildung der Erfindung sieht vor, dass das untere Ende des Scharnierelements im ungeöffneten Zustand des Ausgießelements über das untere Ende der oberen Teile des Ankerrings nach unten in Richtung des Befestigungsflansches vorsteht. Wird der Schraubdeckel nachdem er abgeschraubt wurde aufgeschwenkt, klappt das Scharnierelement mit seinem unteren Ende in Richtung des Schlitzes um, so dass bei einem Öffnungswinkel von 120° bis 150° der Schraubdeckel in seiner Öffnungsstellung mit Bezug auf sein Aufschwenken arretiert ist. In diesem Zustand kann der Schraubdeckel ohne Aufbringung einer Kraft von außen nicht mehr zurückschwenken. Dies hat den großen Vorteil, dass der Schraubdeckel nicht automatisch beim Ausgießen zurückschwenkt und beim Ausgießvorgang nicht mit dem Produkt in Berührung kommt.A preferred embodiment of the invention provides that the lower end of the hinge element, in the unopened state of the pouring element, projects downwards over the lower end of the upper parts of the anchor ring in the direction of the fastening flange. If the screw cap is swung open after it has been unscrewed, the hinge element folds over with its lower end in the direction of the slot, so that at an opening angle of 120° to 150° the screw cap is locked in its open position with respect to its swiveling open. In this state, the screw cap can no longer swing back without applying external force. This has the great advantage that the screw cap does not automatically swing back when pouring and does not come into contact with the product during the pouring process.
In einer besonders bevorzugten Ausgestaltung ist der Schraubdeckel in seiner arretierten Öffnungsstellung radial frei drehbar. Dies hat den großen Vorteil, dass der Schraubdeckel in eine vom Nutzer gewünschte Position gedreht werden kann. In der arretierten Stellung muss dennoch eine leichte Kraft von außen aufgebracht werden, um eine Drehung zu ermöglichen, da durch die Fixierung des Schraubdeckels mit Bezug auf sein Aufschwenken ein erhöhter Reibwiderstand zwischen dem Scharnierelement und dem Basiselement entsteht. Der erhöhte Reibwiderstand ist jedoch auch erwünscht, damit sich der Schraubdeckel beim Ausgießen, hervorgerufen durch die Gravitationskraft, nicht ohne Weiteres in Richtung des Ausgießstrahls bewegt.In a particularly preferred embodiment, the screw cap can be freely rotated radially in its locked open position. This has the great advantage that the screw cap can be turned into a position desired by the user. In the locked position, a slight force must still be applied from the outside in order to enable rotation, since the fixation of the screw cap with respect to its swinging open creates an increased frictional resistance between the hinge element and the base element. However, the increased frictional resistance is also desirable so that the screw cap does not easily move in the direction of the pouring jet when pouring, caused by the gravitational force.
Eine weitere Lehre der Erfindung sieht vor, dass das Scharnierelement mit Bezug auf seine Schwenkachse im ungeöffneten Zustand oberhalb des unteren Drittels des Basiselements angeordnet ist. Durch die Anordnung des Scharnierelements oberhalb des unteren Drittels, wird sichergestellt, dass der Schraubdeckel eine Öffnungsstellung mit einem Öffnungswinkel von 120° bis 150° realisieren kann, bevor der Schraubdeckel auf die Verbundpackung trifft. Da Verbundpackungen typischer Weise keinen wie bei PET-Flaschen vorhandenen Flaschenhals aufweisen, ist die Aufschwenkbewegung des Schraubdeckels deutlich stärker begrenzt als bei PET-Flaschen. Um dennoch für einen angenehmen Ausgießvorgang ausreichend großen Öffnungswinkel zu realisieren, ist eine Anordnung des Scharnierelements möglichst weit oben wünschenswert.A further teaching of the invention provides that the hinge element is arranged above the lower third of the base element with respect to its pivot axis in the unopened state. Arranging the hinge element above the lower third ensures that the screw cap can achieve an open position with an opening angle of 120° to 150° before the screw cap hits the composite pack. Since composite packs typically do not have a bottle neck like PET bottles, the swing-open movement of the screw cap is significantly more limited than with PET bottles. In order to achieve a sufficiently large opening angle for a pleasant pouring process, it is desirable to arrange the hinge element as high as possible.
In einer besonders bevorzugten Ausbildung der Erfindung ist die Schwenkachse des Scharnierelements bei weggeschwenktem Schraubdeckel in axialer Richtung in dem oberen Drittel des Basiselements angeordnet.In a particularly preferred embodiment of the invention, the pivot axis of the hinge element is arranged in the axial direction in the upper third of the base element when the screw cover is pivoted away.
Nach einer bevorzugten Weiterbildung der Erfindung ist vorgesehen, dass am Basiselement unterhalb des Kragens in Richtung des Ankerrings nach außen hervorstehende und sich senkrecht zum Befestigungsflansch erstreckende Rippen vorgesehen sind. Diese Rippen stellen sicher, dass der Ankerring in radialer Richtung immer einen gewissen Abstand zum Basiselement aufweist. Als Folge ist der Ankerring mit Bezug auf das Basiselement in jedem Zustand zentriert.According to a preferred development of the invention it is provided that on the base element below the collar in the direction of the anchor ring outwards protruding ribs which extend perpendicular to the fastening flange are provided. These ribs ensure that the anchor ring is always at a certain distance from the base element in the radial direction. As a result, the anchor ring is centered with respect to the base element in every condition.
Gemäß einer bevorzugten Ausbildung der Erfindung umfassen die Öffnungsmittel ein im Inneren des Basiselements angeordnetes Schneidelement und wenigstens einen im Inneren des Schraubdeckels angeordneten und mit diesem form- oder stoffschlüssig verbundenen Mitnehmersteg, welcher bevorzugt in Umfangsrichtung möglichst nahe am Scharnierelement angebracht ist. Dabei kann das Scharnierelement im Außengewinde des Flansches arretiert werden, um den Schraubdeckel offen zu halten.According to a preferred embodiment of the invention, the opening means comprise a cutting element arranged in the interior of the base element and at least one driver web arranged in the interior of the screw cap and connected to it in a form-fitting or material-locking manner, which is preferably attached as close as possible to the hinge element in the circumferential direction. The hinge element can be locked in the external thread of the flange in order to keep the screw cap open.
Es ist jedoch auch möglich, den Mitnehmersteg jeweils in Umfangsrichtung möglichst weit vom Scharnierelement entfernt anzuordnen. Dies ist dann zweckmäßig, wenn die Scharnierelemente beim Öffnen/Wegkippen des Schraubdeckels nicht im Wege sein sollen. Dies ermöglicht ein sauberes Öffnen/Wegkippen ohne Verhaken von Scharnierelement und oberem Rand der Ausgießtülle.However, it is also possible to arrange the driving bar as far away from the hinge element as possible in the circumferential direction. This is useful if the hinge elements should not be in the way when the screw cap is opened/tilted away. This enables clean opening/tilting away without the hinge element and the upper edge of the pouring spout getting caught.
In bevorzugter Ausgestaltung der Erfindung ist eine Mehrzahl von gleichmäßig über den Umfang verteilt angeordneter Mitnehmerstege vorgesehen.In a preferred embodiment of the invention, a plurality of driver webs arranged evenly distributed over the circumference are provided.
Dieser Mitnehmersteg kann im aufgeschwenkten Zustand zumindest teilweise aus dem Inneren des Schraubdeckels herausragen. Daher ist es besonders wichtig, dass ein ausreichend großer Öffnungswinkel des Schraubdeckels erreicht werden kann.This driving bar can at least partially protrude from the inside of the screw cap when swiveled open. It is therefore particularly important that a sufficiently large opening angle of the screw cap can be achieved.
Das erfindungsgemäße Ausgießelement weist bevorzugt zwischen dem Befestigungsflansch und dem Ankerring oder dem Schraubdeckel wenigstens ein Originalitätssiegel auf. Dieses kann aus einem Band bestehen, dessen eine Ende fest mit dem Ankerring verbunden ist und bei dem das andere Ende mittels einer Sollbruchstelle mit dem Ankerring derart verbunden ist, dass die Sollbruchstelle von wenigstens einem auf dem Befestigungsflansch angeordneten Dornelement beim Aufschrauben des Schraubdeckels aufgebrochen wird und so den Verbraucher auf eine bereits erfolgte Erstöffnung hinweist.The pouring element according to the invention preferably has at least one originality seal between the fastening flange and the anchor ring or the screw cap. This can consist of a band, one end of which is firmly connected to the anchor ring and in which the other end is connected to the anchor ring by means of a predetermined breaking point in such a way that the predetermined breaking point of at least one mandrel element arranged on the fastening flange When the screw cap is unscrewed, it is broken open and the consumer is informed that the first opening has already taken place.
Gemäß einer alternativen Ausführungsform des erfindungsgemäßen Ausgießelements ist unterhalb des Ankerrings ein weiterer Ring angeordnet, der über eine Mehrzahl von Materialbrücken mit dem Ankerring verbunden ist und als Originalitätssiegel dient. Hierbei werden der Schraubdeckel, der Ankerring und der als Originalitätssiegel dienende weitere Ring einteilig hergestellt.According to an alternative embodiment of the pouring element according to the invention, a further ring is arranged below the anchor ring, which is connected to the anchor ring via a plurality of material bridges and serves as a seal of originality. The screw cap, the anchor ring and the additional ring that serves as a seal of authenticity are made in one piece.
Bevorzugt ist der Ring durch ein Blockieren von vom Ring nach innen abstehenden Stegen mit über den Umfang des Basiselements angeordneten Sperrelementen nur begrenzt verdrehbar, so dass er beim ersten Abschrauben des Schraubdeckels durch Abreißen der Materialbrücken vom Ankerring gelöst wird und in seiner Lage am Basiselement verbleibt.Preferably, the ring can only be rotated to a limited extent by blocking webs projecting inwards from the ring with locking elements arranged over the circumference of the base element, so that when the screw cap is unscrewed for the first time, it is detached from the anchor ring by tearing off the material bridges and remains in its position on the base element.
Um sicherzustellen, dass sich der Ring auch bei geöffnetem Schraubdeckel nicht vom Basiselement entfernen lässt, sieht eine weitere Ausgestaltung der Erfindung vor, dass das Basiselement auf seiner Außenseite einen nach außen abstehenden und im Wesentlichen umlaufenden Kragen aufweist, wobei der lichte Innendurchmesser des Kragens kleiner ist als der lichte Abstand zwischen den jeweils gegenüberliegend angeordneten Stegen des Rings.In order to ensure that the ring cannot be removed from the base element even when the screw cap is open, a further embodiment of the invention provides that the base element has an outwardly projecting and essentially circumferential collar on its outside, the clear inside diameter of the collar being smaller as the clear distance between the oppositely arranged webs of the ring.
Eine weitere vorteilhafte Lehre der Erfindung sieht vor, dass der Befestigungsflansch des Ausgießelements mit der Innenseite der Verbundpackung verbunden ist. Eine entsprechende Verbundpackung weist an der Stelle der späteren Ausgießöffnung eine Materialaussparung auf. Zur Montage wird das Ausgießelement durch das Innere der Verbundpackung geführt, in dem Bereich der Materialaussparung positioniert und anschließend mit der Innenseite der Verbundpackung verbunden. Das Basiselement ist bei dieser Ausgestaltung der Erfindung in seinem Inneren im ungeöffneten Zustand packungsseitig verschlossen, so dass das in der Verbundpackung befindliche Produkt im ungeöffneten Zustand nicht in das Ausgießelement fließen kann. Die Öffnungsmittel umfassen bei dieser Ausbildung der Erfindung ein im ungeöffneten Zustand im Inneren des Basiselements angeordnetes und mit diesem stoffschlüssig verbundenes Öffnungselement und wenigstens ein Kraftübertragungselement, das im Inneren des Schraubdeckels angeordnet und mit diesem stoffschlüssig verbunden ist. Das Öffnungselement ist mit dem wenigstens einen Kraftübertragungselement formschlüssig verbunden und wird beim erstmaligen Öffnen des Ausgießelements, ausgelöst durch die Drehung des wenigstens einen Kraftübertragungselements, von dem Basiselement an vorgesehenen Sollbruchstellen abgetrennt, so dass keine stoffschlüssige Verbindung mehr zwischen dem Basiselement und dem Öffnungselement besteht. Das Öffnungselement ist von diesem Zeitpunkt an nur noch mit dem wenigstens einen Kraftübertragungselement formschlüssig verbunden, so dass es nicht in die unter dem Ausgießelement vorhandene Verbundpackung gelangen kann. Das Öffnungselement kann im aufgeschwenkten Zustand zumindest teilweise aus dem Inneren des Schraubdeckels herausragen. Entsprechende Öffnungsmittel sind für sich bereits aus der
