Definitions

  • the invention relates to a package with a closure portion having a fixedly connected to the packaging lid and a cover spanning and mounted against the lid cap, both the lid and the cap each having a spout opening, which can be brought into alignment and the closure cap has a closing region which can be brought into alignment with the pouring opening, the pouring opening being in the cover by a sealing element which can be brought into an at least partially open state of the sealing element for emptying the packaging, and the sealing element is cap-shaped relative to the packaging is curved to the outside and has at least one radially outwardly projecting flange.
  • a packaging of this kind is from the DE 197 06 112 C2 known.
  • this known packaging which is described in particular as a beverage can, there is the problem that after filling this can and after the Aufbördein the lid, the liquid filled in the can between the lid and the cap can pass, because the opening in the lid before the application of the cap is not closed.
  • Other problems of the known packaging consist in the almost impossible cleaning of soiled lid before applying the cap without contamination of the packaged goods with detergent or dirt, and the very difficult execution of an understandable for the end user originality closure - especially without additional components.
  • Such packages are particularly suitable for free-flowing or flowable products.
  • beverage cans of the type mentioned are especially in the US 5,692,633 A , of the DE 201 14 741 U1 , of the WO 02/18225 A1 , of the US 3,726,432 A , of the DE 297 12 852 U1 , of the DE 298 12 936 U1 , of the EP 0 340 835 A , of the WO 02/18225 A and the disclosing the preamble of claim 1 WO 2007/054568 A1 described.
  • the object of the invention is to design the packaging so that after filling the packaging and applying the lid and the subsequent application of the cap, the filled product can not get between the lid and cap. Further objects of the invention are a secure closing of the lid already at the time of cleaning after the filling of the packaging, as well as the production of a tamper-evident closure.
  • the sealing element is elastic. This allows deformation due to overpressure in the package or as a result of an applied bias in the connection of the cap and lid.
  • the elastic sealing element can then - if it gets under an opening in the cap - hineineruiten into this opening. This makes it easier to grip the sealing element or act with the cap on the sealing element.
  • the invention also has an advantageous effect, in particular, since no product particles are present between the lid and the closure cap which could lead to a disturbance in the mobility of the closure cap.
  • the convex configuration proves to be particularly advantageous if a handle for opening the sealing element is provided, it is advantageous if the handle is firmly connected to the sealing element or integrated in the closure cap. After twisting the cap in the open position pushes namely the outwardly curved cap through the spout opening in the cap to the outside, whereby the handle for opening the sealing element can be easily detected.
  • the lid connected to the packaging may have any shape. It is important that the shape is chosen so that a cap can be moved relative to the lid.
  • an elongated lid is provided in which the closure cap is displaced laterally relative to the lid.
  • the lid connected to the packaging is circular. This allows the cap to rotate relative to the lid to expose or seal the spout opening.
  • the cap is rotatably mounted.
  • the cap can be attached with grippers on the lid. For this purpose, individual webs are sufficient to arrange the functions of the cap there. However, it is advantageous if the closure region has a closure cap spanning the entire cover. This will give a special stability reaches the cap and there are a variety of ways to form the cap, to arrange a variety of functions there.
  • both the lid and the closure cap each have an eccentric spout opening.
  • the spout opening of the lid is associated with a sealing area surrounding the spout opening.
  • the closing area of the closure cap is assigned a sealing area which surrounds the closing area.
  • This sealing region can be arranged both on the cover and on the closure cap, it can lie between the lid and the closure cap or can also be formed in one piece with the lid and / or closure cap.
  • the sealing region has a seal.
  • seals are to be understood as a seal in the present case, but a seal is also understood to mean a specially designed region of the cover or the closure cap, which causes a special sealing effect.
  • a particular embodiment provides that an effective between the lid and the cap lifting device is provided, which causes a reversal of the sealing effect of a sealing area between the lid and cap during rotation of the cap.
  • the transfer of the sealing element in an at least partially open state is facilitated if the sealing element has a predetermined breaking point.
  • This can be designed so that the sealing element is only partially opened, or the predetermined breaking point can also allow a complete opening of the sealing element.
  • a predetermined breaking point is also advantageous if the handle is integrated in the closure cap and in particular is designed as a shape of the closure cap and engages with the sealing element during rotation thereof.
  • the sealing element can already be transferred into an at least partially open state during rotation of the closure cap.
  • the handle can also be held as a punching tool in the cap movable.
  • the punching tool is to be pressed down into the open position after the closure cap has been rotated, as a result of which the sealing element is partially or completely severed depending on the design of the cutting edge of the punching tool.
  • the sealing element may be fixable with a flange on the inside or on the outside.
  • An advantageous embodiment also results from the fact that the edge region of the opening is received in the lid between two flanges of the sealing element.
  • This embodiment is advantageous because on the one hand, the sealing element can be particularly firmly arranged on the lid and also in this embodiment, the upper of the two flanges in the closed position of the closure cap the same surround as a seal.
  • This type of seal training has the advantage that here too an intimate connection between the seal and the lid can be produced.
  • the closure cap in the closing region has a recess for at least partially receiving the sealing element, this has an advantage, in particular, when the sealing element is curved in the shape of a cap to the outside. In this at least partially received position of the sealing element in a recess of the closure cap, the sealing element can be destroyed during rotation of the cap particularly easy for opening.
  • the closure cap may be made of such a material that it is advantageous to form both the spout opening and the seal surrounding the closing area in one piece with the closure cap.
  • both the spout opening and the sealing area surrounding the seal is attached to the closure cap. It is particularly advantageous if the seals are partially embedded in recesses of the cap.
  • sealing element remains connected in the open state with the lid, because this avoids that the separated Sealing part is distributed with the contents of the package, which would be particularly disadvantageous in beverage cans when drinking directly from the can.
  • the sealing element after opening protrudes into the packaging with bias, so that it can not interfere with the emptying of the packaging.
  • the sealing element engage with grippers fastened to the closure cap.
  • the grippers may seize the sealing element or at least a portion of the sealing element prior to its separation while holding the separation and preferably even retain it after its separation.
  • sealing element is locked after opening with the closure cap.
  • the sealing element or the separated part of the sealing element firmly hangs on the closure cap, where it is lifted as far as possible captive.
  • the lifting device comprises a locking cam formed on the cover or the cap and a detent recess cooperating therewith, wherein the detent cam and the detent recess cooperating therewith determine the two positions of the closure cap by their geometric configuration, in which the two spout openings on the one hand and the closing area of the one on the other hand Cap with the spout opening in the lid aligned.
  • This configuration not only achieves the necessary lifting of the closure cap during the movement of the closure cap relative to the lid, but also the two operating positions of the closure cap are determined at the same time, so that it is ensured that the packaging is completely opened in the one position and in the one position completely closed.
  • a second opening is provided in the lid, which is closed by a second preferably elastic sealing element. This second opening serves as a vent when the sealing element is destroyed.
  • the second opening in the lid is formed in a spout opening substantially opposite sector. As a result, the air can flow in particularly low when emptying the packaging.
  • closure cap is provided with a projection which penetrates into the open position of the closure cap in the second sealing element and this opens.
  • the closure cap has a further sealing area, which seals a second sealing element in the closed position.
  • the second sealing element which usually serves as aeration when pouring liquids, is opened after its opening and thus allows leakage of liquid.
  • the further sealing region which is preferably designed as a seal, makes it possible, in particular when the can is closed, to seal the opened second sealing element.
  • sealing element There are several ways to open the sealing element. In addition to the described possibilities of a pull-out handle or a press-in punch, it is also possible to sever the sealing element horizontally. For this purpose, it is proposed that the closure cap has a cutting edge.
  • a simple embodiment provides that the cutting edge is arranged in the spout opening. If the sealing element enters the pouring opening, it can be cut off with the cutting edge. Subsequently, the cap is rotated back slightly, whereupon the contents of the package can emerge from the spout opening.
  • the cutting edge is arranged in a further opening of the closure cap. This separates the functions of cutting off part of the seal and leaking the contents of the package from the package.
  • a simple embodiment provides that the further opening is a slot. This makes it possible to enter a sealing element aligned with the oblong hole in the opening and to open the sealing element by a movement of the closure cap relative to the lid.
  • a particularly simple interaction between a blade fastened to the closure cap and a seal is achieved in that a part of a prestressed seal projects into an opening of the closure cap when the closure cap is moved relative to the lid.
  • the seal may in this case be biased by a special deformation or by the pressure of the cap against the seal as long as under bias until the seal protrudes into an opening of the cap.
  • the part of the prestressed seal audibly jumps into a position, in particular an opening of the closure cap, when the closure cap is moved relative to the lid. With a "pop” the seal jumps into the opening, where it is then cut off by moving the cap relative to the lid.
  • An acoustic signal can also be achieved by the seal jumps into a recess in the cap and thereby indicates a specific position of the lid relative to the cap - preferably audible.
  • the sealing element has a peripheral weakening for the engagement of the cutting edge.
  • the opened seal forms a sealing area between the cover and the closure cap. It is important to ensure that even after removing a portion of the seal to the opening of the seal still enough sealing material remains to allow sufficient sealing between the lid and cap.
  • the closure cap may have an opening with a cover.
  • the cover then forms a cavity for receiving at least a portion of the seal.
  • This cover may be integrally formed with the cap or be connected as an additional part with her. In this case, it can preferably be provided that the opening with the cutting edge has a cover.
  • seal and the spout opening in the closure cap are formed such that the seal can not penetrate into the spout opening.
  • the cap is movable in one direction only relative to the lid.
  • the cap is made of a multi-component material. This makes it possible to provide particularly strong materials for connecting the closure cap and lid, while other material qualities are required for the sealing regions.
  • closure cap has a metal frame with a plastic insert.
  • an elasticity of the sealing element is necessary thus the sealing element is deformable for engagement with the closure cap. This makes it possible to support the sealing element with the cap in the closed state.
  • the sealing element has a sealing against the closure cap frame.

Description

Die Erfindung bezieht sich auf eine Verpackung mit einem Verschlussbereich, der einen mit der Verpackung fest verbundenen Deckel und eine den Deckel überspannende und gegenüber dem Deckel gelagerte Verschlusskappe, wobei sowohl der Deckel als auch die Verschlusskappe jeweils eine Ausgussöffnung, die in eine fluchtende Ausrichtung bringbar sind und die Verschlusskappe einen mit der Ausgussöffnung in fluchtende Ausrichtung bringbaren Schließbereich aufweist, wobei die Ausgussöffnung im Deckel durch ein Siegelelement ist, das für das Entleeren der Verpackung in einen zumindest teilweise geöffneten Zustand des Siegelelementes bringbar ist, und das Siegelelement in Bezug auf die Verpackung kappenförmig nach außen gewölbt ist und zumindest einen radial nach außen abstehenden Flansch aufweist.The invention relates to a package with a closure portion having a fixedly connected to the packaging lid and a cover spanning and mounted against the lid cap, both the lid and the cap each having a spout opening, which can be brought into alignment and the closure cap has a closing region which can be brought into alignment with the pouring opening, the pouring opening being in the cover by a sealing element which can be brought into an at least partially open state of the sealing element for emptying the packaging, and the sealing element is cap-shaped relative to the packaging is curved to the outside and has at least one radially outwardly projecting flange.

Eine Verpackung dieser Art ist aus der DE 197 06 112 C2 bekannt. Bei dieser bekannten Verpackung, die insbesondere als Getränkedose beschrieben ist, besteht das Problem, dass nach dem Befüllen dieser Dose und nach dem Aufbördein des Deckels, die in die Dose eingefüllte Flüssigkeit zwischen den Deckel und die Verschlusskappe gelangen kann, weil die Öffnung im Deckel vor der Aufbringung der Verschlusskappe nicht geschlossen ist. Weitere Probleme der bekannten Verpackung bestehen in der nahezu unmöglichen Reinigung verschmutzter Deckel vor Aufbringen der Verschlusskappe ohne Kontaminierung des Packgutes mit Reinigungsmittel oder Schmutz, sowie der sehr schwierigen Ausführung eines für den Endkunden verständlichen Originalitätsverschlusses - insbesondere ohne zusätzliche Bauteile. Derartige Verpackungen sind insbesondere für rieselfähige oder fließfähige Produkte geeignet.A packaging of this kind is from the DE 197 06 112 C2 known. In this known packaging, which is described in particular as a beverage can, there is the problem that after filling this can and after the Aufbördein the lid, the liquid filled in the can between the lid and the cap can pass, because the opening in the lid before the application of the cap is not closed. Other problems of the known packaging consist in the almost impossible cleaning of soiled lid before applying the cap without contamination of the packaged goods with detergent or dirt, and the very difficult execution of an understandable for the end user originality closure - especially without additional components. Such packages are particularly suitable for free-flowing or flowable products.

Weitere Getränkedosen der eingangs erwähnten Art werden insbesondere auch in der US 5,692,633 A , der DE 201 14 741 U1 , der WO 02/18225 A1 , der US 3,726,432 A , der DE 297 12 852 U1 , der DE 298 12 936 U1 , der EP 0 340 835 A , der WO 02/18225 A sowie der den Oberbegriff des Anspruchs 1 offenbarenden WO 2007/054568 A1 beschrieben.Other beverage cans of the type mentioned are especially in the US 5,692,633 A , of the DE 201 14 741 U1 , of the WO 02/18225 A1 , of the US 3,726,432 A , of the DE 297 12 852 U1 , of the DE 298 12 936 U1 , of the EP 0 340 835 A , of the WO 02/18225 A and the disclosing the preamble of claim 1 WO 2007/054568 A1 described.

Aufgabe der Erfindung ist es, die Verpackung so auszugestalten, dass nach dem Befüllen der Verpackung und Aufbringen des Deckels sowie dem anschließenden Aufbringen der Verschlusskappe, das eingefüllte Produkt nicht zwischen Deckel und Verschlusskappe gelangen kann. Weitere Aufgaben der Erfindung sind ein sicheres Verschließen des Deckels bereits zum Zeitpunkt der Reinigung nach der Befüllung der Verpackung, sowie die Herstellung eines Originalitätsverschlusses.The object of the invention is to design the packaging so that after filling the packaging and applying the lid and the subsequent application of the cap, the filled product can not get between the lid and cap. Further objects of the invention are a secure closing of the lid already at the time of cleaning after the filling of the packaging, as well as the production of a tamper-evident closure.

Diese Aufgabe wird ausgehend von einer Verpackung der eingangs erläuterten Art erfindungsgemäß dadurch gelöst, dass das Siegelelement elastisch ausgebildet ist. Dies ermöglicht eine Verformung aufgrund eines Überdrucks in der Verpackung oder in Folge einer aufgebrachten Vorspannung bei der Verbindung von Verschlusskappe und Deckel. Das elastische Siegelelement kann dann - sofern es unter eine Öffnung in der Verschlusskappe gelangt - sich in diese Öffnung hineinerstrecken. Dies erleichtert es, das Siegelelement zu greifen oder mit der Verschlusskappe auf das Siegelelement einzuwirken.This object is achieved on the basis of a package of the type described above according to the invention in that the sealing element is elastic. This allows deformation due to overpressure in the package or as a result of an applied bias in the connection of the cap and lid. The elastic sealing element can then - if it gets under an opening in the cap - hineinerstrecken into this opening. This makes it easier to grip the sealing element or act with the cap on the sealing element.

Wenn also die Verpackung, wie dies beim Befüllen mit Flüssigkeiten teilweise der Fall ist, überfüllt wird, um einen Luft- bzw. Gaseinschluss beim Aufbördeln des Deckels zu vermeiden, so ist bei dieser erfindungsgemäßen Ausgestaltung sichergestellt, dass keine Flüssigkeit durch die Ausgussöffnung auf den Deckel gelangen kann, weil die Ausgussöffnung durch ein Siegelelement verschlossen ist.Thus, if the packaging, as is partially the case when filling with liquids, is overfilled in order to avoid an air or gas inclusion when flaring the lid, it is ensured in this embodiment according to the invention that no liquid flows through the pouring opening onto the lid can get, because the spout opening is closed by a sealing element.

Es kann sich somit nach dem Aufbringen der Verschlusskappe keine Flüssigkeit zwischen Deckel und Verschlusskappe befinden, wodurch sämtliche Hygieneprobleme beseitigt sind. Bei rieselfähigen Produkten wirkt sich die Erfindung auch insbesondere deshalb vorteilhaft aus, da keine Produktteilchen zwischen Deckel und Verschlusskappe vorhanden sind, die zu einer Störung in der Beweglichkeit der Verschlusskappe führen könnten.It can thus be after the application of the cap no liquid between the lid and cap, whereby all hygiene problems are eliminated. In the case of free-flowing products, the invention also has an advantageous effect, in particular, since no product particles are present between the lid and the closure cap which could lead to a disturbance in the mobility of the closure cap.

Die nach außen gewölbte Ausgestaltung erweist sich insbesondere dann als vorteilhaft, wenn eine Handhabe zum Öffnen des Siegelelementes vorgesehen ist, wobei es vorteilhaft ist, wenn die Handhabe mit dem Siegelelement fest verbunden oder in der Verschlusskappe integriert ist. Nach dem Verdrehen der Verschlusskappe in die Offenstellung drückt nämlich die nach außen gewölbte Kappe durch die Ausgussöffnung in der Verschlusskappe nach außen, wodurch die Handhabe zum Öffnen des Siegelelementes leichter erfasst werden kann.The convex configuration proves to be particularly advantageous if a handle for opening the sealing element is provided, it is advantageous if the handle is firmly connected to the sealing element or integrated in the closure cap. After twisting the cap in the open position pushes namely the outwardly curved cap through the spout opening in the cap to the outside, whereby the handle for opening the sealing element can be easily detected.

Der mit der Verpackung verbundene Deckel kann beliebige Formen aufweisen. Wichtig ist es, dass die Form so gewählt ist, dass eine Verschlusskappe relativ zum Deckel bewegt werden kann. Bei einer länglichen Verpackung bietet sich ein länglicher Deckel an, bei dem die Verschlusskappe lateral zum Deckel verschoben wird. Im Hinblick auf die Vielzahl der als Verpackung verwendeten runden Dosen ist es vorteilhaft, wenn der mit der Verpackung verbundene Deckel kreisförmig ist. Dies ermöglicht es die Verschlusskappe relativ zum Deckel zu verdrehen, um die Ausgussöffnung frei zu legen oder abzudichten.The lid connected to the packaging may have any shape. It is important that the shape is chosen so that a cap can be moved relative to the lid. In an elongated packaging, an elongated lid is provided in which the closure cap is displaced laterally relative to the lid. In view of the plurality of round cans used as packaging, it is advantageous if the lid connected to the packaging is circular. This allows the cap to rotate relative to the lid to expose or seal the spout opening.

Daher wird weiterbildend vorgeschlagen, dass die Verschlusskappe drehbar gelagert ist.Therefore, it is further proposed that the cap is rotatably mounted.

Die Verschlusskappe kann mit Greifern am Deckel befestigt sein. Hierzu reichen einzelne Stege aus, um dort die Funktionen der Verschlusskappe anzuordnen. Vorteilhaft ist es jedoch, wenn der Verschlussbereich eine den gesamten Deckel überspannende Verschlusskappe aufweist. Dadurch wird eine besondere Stabilität der Verschlusskappe erreicht und es bietet sich eine Vielzahl an Möglichkeiten zur Ausbildung der Verschlusskappe, um dort verschiedenartigste Funktionen anzuordnen.The cap can be attached with grippers on the lid. For this purpose, individual webs are sufficient to arrange the functions of the cap there. However, it is advantageous if the closure region has a closure cap spanning the entire cover. This will give a special stability reaches the cap and there are a variety of ways to form the cap, to arrange a variety of functions there.

Insbesondere bei einem runden Deckel ist es konstruktiv besonders vorteilhaft, wenn sowohl der Deckel als auch die Verschlusskappe jeweils eine außermittige Ausgussöffnung aufweisen.In particular, in the case of a round lid, it is structurally particularly advantageous if both the lid and the closure cap each have an eccentric spout opening.

Vor allem bei der Verwendung von härteren Materialien für die Verschlusskappe und den Deckel ist es vorteilhaft, wenn der Ausgussöffnung des Deckels ein Dichtbereich zugeordnet ist, der die Ausgussöffnung umgibt.Especially when using harder materials for the cap and the lid, it is advantageous if the spout opening of the lid is associated with a sealing area surrounding the spout opening.

Vorteilhaft ist es, wenn dem Schließbereich der Verschlusskappe ein Dichtbereich zugeordnet ist, der den Schließbereich umgibt. Dieser Dichtbereich kann sowohl am Deckel als auch an der Verschlusskappe angeordnet sein, er kann zwischen Deckel und Verschlusskappe liegen oder auch einstückig mit Deckel und/oder Verschlusskappe ausgebildet sein.It is advantageous if the closing area of the closure cap is assigned a sealing area which surrounds the closing area. This sealing region can be arranged both on the cover and on the closure cap, it can lie between the lid and the closure cap or can also be formed in one piece with the lid and / or closure cap.

Vorteilhaft ist es, wenn der Dichtbereich eine Dichtung aufweist. Als Dichtung sind im vorliegenden Fall nicht nur separate Dichtungen zu verstehen, sondern als Dichtung wird auch ein speziell ausgebildeter Bereich des Deckels oder der Verschlusskappe verstanden, der eine besondere Dichtwirkung hervorruft.It is advantageous if the sealing region has a seal. Not only separate seals are to be understood as a seal in the present case, but a seal is also understood to mean a specially designed region of the cover or the closure cap, which causes a special sealing effect.

Auch wenn im Rahmen der Erfindung von einem Dichtbereich gesprochen wird, so schließt dies nicht aus, dass beispielsweise auch der gesamte Deckel oder die gesamte Verschlusskappe aus einem Dichteigenschaften aufweisendem Material ausgebildet sein können, um die geforderte Abdichtung zu erzielen.Even if spoken of in the context of the invention of a sealing area, this does not exclude that, for example, the entire lid or the entire cap can be formed of a sealing properties exhibiting material to achieve the required seal.

Eine besondere Ausführungsvariante sieht vor, dass eine zwischen dem Deckel und der Verschlusskappe wirksame Hebevorrichtung vorgesehen ist, die beim Verdrehen der Verschlusskappe ein Aufheben der Dichtwirkung eines Dichtbereiches zwischen Deckel und Verschlusskappe bewirkt.A particular embodiment provides that an effective between the lid and the cap lifting device is provided, which causes a reversal of the sealing effect of a sealing area between the lid and cap during rotation of the cap.

Das Überführen des Siegelelementes in einen zumindest teilweise geöffneten Zustand wird dann erleichtert, wenn das Siegelelement eine Sollbruchstelle aufweist. Diese kann so ausgebildet sein, dass das Siegelelement nur teilweise geöffnet wird, oder die Sollbruchstelle kann auch ein vollständiges Öffnen des Siegelelementes zulassen.The transfer of the sealing element in an at least partially open state is facilitated if the sealing element has a predetermined breaking point. This can be designed so that the sealing element is only partially opened, or the predetermined breaking point can also allow a complete opening of the sealing element.

Das Vorhandensein einer Sollbruchstelle ist auch dann vorteilhaft, wenn die Handhabe in der Verschlusskappe integriert ist und insbesondere als Ausformung der Verschlusskappe ausgebildet ist und beim Verdrehen desselben mit dem Siegelelement in Eingriff kommt. Dadurch kann insbesondere in Verbindung mit der Sollbruchstelle bereits beim Verdrehen der Verschlusskappe das Siegelelement in einen zumindest teilweise geöffneten Zustand überführt werden.The presence of a predetermined breaking point is also advantageous if the handle is integrated in the closure cap and in particular is designed as a shape of the closure cap and engages with the sealing element during rotation thereof. As a result, in particular in connection with the predetermined breaking point, the sealing element can already be transferred into an at least partially open state during rotation of the closure cap.

Die Handhabe kann auch als Stanzwerkzeug in der Verschlusskappe bewegbar gehalten sein. Dabei ist zum Öffnen des Siegelelementes das Stanzwerkzeug nach dem Verdrehen der Verschlusskappe in die Offenstellung herunterzudrücken, wodurch das Siegelelement je nach Ausbildung der Schneide des Stanzwerkzeuges teilweise oder vollständig durchtrennt wird.The handle can also be held as a punching tool in the cap movable. To open the sealing element, the punching tool is to be pressed down into the open position after the closure cap has been rotated, as a result of which the sealing element is partially or completely severed depending on the design of the cutting edge of the punching tool.

Das Siegelelement kann mit einem Flansch an der Innenseite oder an der Außenseite festlegbar sein.The sealing element may be fixable with a flange on the inside or on the outside.

Eine vorteilhafte Ausgestaltung ergibt sich auch dadurch, dass der Randbereich der Öffnung im Deckel zwischen zwei Flanschen des Siegelelementes aufgenommen ist. Diese Ausgestaltung ist deshalb vorteilhaft, weil einerseits das Siegelelement besonders fest am Deckel angeordnet werden kann und außerdem kann bei dieser Ausgestaltung der obere der beiden Flansche in der Schließstellung der Verschlusskappe den Schließbereich desselben als Dichtung umgeben. Diese Art der Dichtungsausbildung hat den Vorteil, dass auch hier eine innige Verbindung zwischen Dichtung und Deckel herstellbar ist.An advantageous embodiment also results from the fact that the edge region of the opening is received in the lid between two flanges of the sealing element. This embodiment is advantageous because on the one hand, the sealing element can be particularly firmly arranged on the lid and also in this embodiment, the upper of the two flanges in the closed position of the closure cap the same surround as a seal. This type of seal training has the advantage that here too an intimate connection between the seal and the lid can be produced.

Wenn die Verschlusskappe im Schließbereich eine Aussparung zur zumindest teilweisen Aufnahme des Siegelelementes aufweist, so hat dies insbesondere dann einen Vorteil, wenn das Siegelelement kappenförmig nach außen gewölbt ist. In dieser zumindest teilweise aufgenommenen Position des Siegelelementes in einer Aussparung der Verschlusskappe kann das Siegelelement beim Verdrehen der Verschlusskappe besonders leicht für das Öffnen zerstört werden.If the closure cap in the closing region has a recess for at least partially receiving the sealing element, this has an advantage, in particular, when the sealing element is curved in the shape of a cap to the outside. In this at least partially received position of the sealing element in a recess of the closure cap, the sealing element can be destroyed during rotation of the cap particularly easy for opening.

Die Verschlusskappe kann aus einem solchen Material hergestellt sein, dass es vorteilhaft ist, sowohl die die Ausgussöffnung als auch die den Schließbereich umgebende Dichtung einstückig mit der Verschlusskappe auszubilden.The closure cap may be made of such a material that it is advantageous to form both the spout opening and the seal surrounding the closing area in one piece with the closure cap.

Es ist aber auch möglich, dass sowohl die die Ausgussöffnung als auch die den Schließbereich umgebende Dichtung an der Verschlusskappe befestigt ist. Hierbei ist es besonders vorteilhaft, wenn die Dichtungen in Aussparungen der Verschlusskappe teilweise eingelassen sind.But it is also possible that both the spout opening and the sealing area surrounding the seal is attached to the closure cap. It is particularly advantageous if the seals are partially embedded in recesses of the cap.

Es ist besonders vorteilhaft, wenn das Siegelelement im geöffneten Zustand mit dem Deckel verbunden bleibt, weil hierdurch vermieden wird, dass das abgetrennte Siegelteil mit dem Inhalt der Verpackung ausgeschüttet wird, was insbesondere bei Getränkedosen nachteilig wäre, wenn man direkt aus der Dose trinkt.It is particularly advantageous if the sealing element remains connected in the open state with the lid, because this avoids that the separated Sealing part is distributed with the contents of the package, which would be particularly disadvantageous in beverage cans when drinking directly from the can.

Bei dieser Ausgestaltung ist es vorteilhaft, wenn das Siegelelement nach dem Öffnen mit Vorspannung in die Verpackung hinein ragt, so dass es beim Entleeren der Verpackung nicht stören kann.In this embodiment, it is advantageous if the sealing element after opening protrudes into the packaging with bias, so that it can not interfere with the emptying of the packaging.

Alternativ oder kumulativ wird vorgeschlagen, dass das Siegelelement beim Bewegen der Verschlusskappe relativ zum Deckel mit an der Verschlusskappe befestigten Greifern in Eingriff gerät. Dies ermöglicht es ein abgetrenntes oder abzutrennendes Teil des Siegelelementes an der Verschlusskappe zu halten, damit es weder in die Verpackung hineinfällt noch irgendwo in die Umgebung fällt. Die Greifer können das Siegelelement oder zumindest einen Teil des Siegelelementes vor seiner Abtrennung ergreifen, während der Abtrennung halten und vorzugsweise sogar noch nach seiner Abtrennung festhalten.Alternatively or cumulatively, it is proposed that, when the closure cap is moved relative to the lid, the sealing element engage with grippers fastened to the closure cap. This makes it possible to keep a separate or separable part of the sealing element on the cap, so that it does not fall into the packaging nor fall anywhere in the area. The grippers may seize the sealing element or at least a portion of the sealing element prior to its separation while holding the separation and preferably even retain it after its separation.

Hierbei ist es vorteilhaft, wenn das Siegelelement nach dem Öffnen mit der Verschlusskappe verrastet ist. Dadurch hängt das Siegelelement bzw. das abgetrennte Teil des Siegelelementes fest an der Verschlusskappe, wo es möglichst unverlierbar aufgehoben ist.It is advantageous if the sealing element is locked after opening with the closure cap. As a result, the sealing element or the separated part of the sealing element firmly hangs on the closure cap, where it is lifted as far as possible captive.

Die Hebevorrichtung umfasst einen am Deckel oder der Verschlusskappe ausgebildeten Rastnocken und eine am jeweils zugeordneten Teil ausgebildete Rastmulde, wobei der Rastnocken und die hiermit zusammenwirkende Rastmulde durch ihre geometrische Gestaltung die beiden Lagen der Verschlusskappe bestimmen, in denen einerseits die beiden Ausgussöffnungen und andererseits der Schließbereich der Verschlusskappe mit der Ausgussöffnung im Deckel fluchtet. Durch diese Ausgestaltung ist nicht nur das notwendige Anheben der Verschlusskappe während der Bewegung der Verschlusskappe relativ zum Deckel erzielt, sondern es werden gleichzeitig auch die beiden Betriebslagen der Verschlusskappe festgelegt, so dass sichergestellt ist, dass in der einen Lage die Verpackung vollständig geöffnet und in der anderen Lage vollständig verschlossen ist.The lifting device comprises a locking cam formed on the cover or the cap and a detent recess cooperating therewith, wherein the detent cam and the detent recess cooperating therewith determine the two positions of the closure cap by their geometric configuration, in which the two spout openings on the one hand and the closing area of the one on the other hand Cap with the spout opening in the lid aligned. This configuration not only achieves the necessary lifting of the closure cap during the movement of the closure cap relative to the lid, but also the two operating positions of the closure cap are determined at the same time, so that it is ensured that the packaging is completely opened in the one position and in the one position completely closed.

Um das Entleeren der Verpackung, insbesondere wenn es sich um Flüssigkeit handelt, zu erleichtern bzw. den Entleerungsvorgang zu beschleunigen, ist in weiterer Ausgestaltung der Erfindung im Deckel eine zweite Öffnung vorgesehen, die durch ein zweites vorzugsweise elastisches Siegelelement verschlossen ist. Diese zweite Öffnung dient, wenn das Siegelelement zerstört ist, als Belüftungsöffnung.In order to facilitate the emptying of the packaging, in particular when it comes to liquid, or to accelerate the emptying process, in a further embodiment of the invention, a second opening is provided in the lid, which is closed by a second preferably elastic sealing element. This second opening serves as a vent when the sealing element is destroyed.

Für den Vorgang der Belüftung ist es vorteilhaft, wenn die zweite Öffnung im Deckel in einem der Ausgussöffnung im wesentlichen gegenüberliegenden Sektor ausgebildet ist. Hierdurch kann die Luft beim Entleeren der Verpackung besonders günstig nachströmen.For the process of ventilation, it is advantageous if the second opening in the lid is formed in a spout opening substantially opposite sector. As a result, the air can flow in particularly low when emptying the packaging.

Zum Öffnen des Siegelelementes für diese zweite Öffnung ist es vorteilhaft, wenn die Verschlusskappe mit einem Vorsprung versehen ist, der in der Offenstellung der Verschlusskappe in das zweite Siegelelement eindringt und dieses öffnet.To open the sealing element for this second opening, it is advantageous if the closure cap is provided with a projection which penetrates into the open position of the closure cap in the second sealing element and this opens.

Besonders vorteilhaft ist es, wenn die Verschlusskappe einen weiteren Dichtbereich aufweist, der in der Geschlossenstellung ein zweites Siegelelement abdichtet. Das zweite Siegelelement, das in der Regel als Belüftung beim Ausgießen von Flüssigkeiten dient, ist nach seiner Öffnung geöffnet und erlaubt somit Austreten von Flüssigkeit. Der weitere Dichtbereich, der vorzugsweise als Dichtung ausgebildet ist, erlaubt es insbesondere, wenn die Dose geschlossen ist, das geöffnete zweite Siegelelement abzudichten.It is particularly advantageous if the closure cap has a further sealing area, which seals a second sealing element in the closed position. The second sealing element, which usually serves as aeration when pouring liquids, is opened after its opening and thus allows leakage of liquid. The further sealing region, which is preferably designed as a seal, makes it possible, in particular when the can is closed, to seal the opened second sealing element.

Es gibt verschiedene Möglichkeiten, das Siegelelement zu öffnen. Neben den beschriebenen Möglichkeiten einer herausziehbaren Handhabe oder einer hineinpressbaren Stanze besteht auch die Möglichkeit, das Siegelelement waagerecht zu durchtrennen. Hierzu wird vorgeschlagen, dass die Verschlusskappe eine Schneide aufweist.There are several ways to open the sealing element. In addition to the described possibilities of a pull-out handle or a press-in punch, it is also possible to sever the sealing element horizontally. For this purpose, it is proposed that the closure cap has a cutting edge.

Eine einfache Ausführungsvariante sieht vor, dass die Schneide in der Ausgussöffnung angeordnet ist. Wenn das Siegelelement in die Ausgussöffnung eintritt, kann es mit der Schneide abgeschnitten werden. Anschließend wird die Verschlusskappe wieder etwas zurück gedreht, woraufhin der Inhalt der Verpackung aus der Ausgussöffnung heraustreten kann.A simple embodiment provides that the cutting edge is arranged in the spout opening. If the sealing element enters the pouring opening, it can be cut off with the cutting edge. Subsequently, the cap is rotated back slightly, whereupon the contents of the package can emerge from the spout opening.

Im praktischen Umgang mit der Verpackung hat es sich als vorteilhaft herausgestellt, wenn die Schneide in einer weiteren Öffnung der Verschlusskappe angeordnet ist. Dadurch werden die Funktionen des Abschneidens eines Teils des Siegels und des Austretens des Verpackungsinhaltes aus der Verpackung getrennt.In practical handling of the packaging, it has proven to be advantageous if the cutting edge is arranged in a further opening of the closure cap. This separates the functions of cutting off part of the seal and leaking the contents of the package from the package.

Eine einfache Ausführungsform sieht vor, dass die weitere Öffnung ein Langloch ist. Dies ermöglicht es, ein mit dem Langloch fluchtendes Siegelelement in die Öffnung eintreten zu lassen und durch eine Bewegung der Verschlusskappe relativ zum Deckel das Siegelelement zu öffnen.A simple embodiment provides that the further opening is a slot. This makes it possible to enter a sealing element aligned with the oblong hole in the opening and to open the sealing element by a movement of the closure cap relative to the lid.

Insbesondere, wenn in der Verpackung unter Druck stehende Flüssigkeiten wie CO2-haltige Getränke transportiert werden, entstehen häufig Drücke von mehreren bar. Wenn in der geschlossenen Position der Verschlusskappe der Schließbereich der Verschlusskappe gegen das Siegel drückt, kann auch ein weniger stabil ausgebildetes Siegel diesen Drücken stand halten.In particular, when in the packaging pressurized liquids such as CO 2 -containing drinks are transported, often pressures of several bar. When in the closed position of the closure cap the closing area the cap presses against the seal, even a less stable seal can withstand these pressures.

Ein besonders einfaches Zusammenwirken zwischen einer an der Verschlusskappe befestigten Schneide und einem Siegel wird dadurch erreicht, dass ein Teil eines vorgespannten Siegels beim Bewegen der Verschlusskappe relativ zum Deckel in eine Öffnung der Verschlusskappe hineinragt. Das Siegel kann hierbei durch eine spezielle Verformung vorgespannt sein oder durch den Druck der Verschlusskappe gegen das Siegel solange unter Vorspannung stehen, bis das Siegel in eine Öffnung der Verschlusskappe hineinragt.A particularly simple interaction between a blade fastened to the closure cap and a seal is achieved in that a part of a prestressed seal projects into an opening of the closure cap when the closure cap is moved relative to the lid. The seal may in this case be biased by a special deformation or by the pressure of the cap against the seal as long as under bias until the seal protrudes into an opening of the cap.

Besonders vorteilhaft ist es, wenn der Teil des vorgespannten Siegels beim Bewegen der Verschlusskappe relativ zum Deckel hörbar in eine Position, insbesondere eine Öffnung der Verschlusskappe, hineinspringt. Mit einem "Plopp" springt das Siegel in die Öffnung, in der es anschließend durch ein Bewegen der Verschlusskappe relativ zum Deckel abgeschnitten wird. Ein akustisches Signal kann aber auch erzielt werden, indem das Siegel in eine Vertiefung in der Verschlusskappe springt und dadurch eine spezielle Position des Deckels relativ zur Verschlusskappe - vorzugsweise hörbar - anzeigt.It is particularly advantageous if the part of the prestressed seal audibly jumps into a position, in particular an opening of the closure cap, when the closure cap is moved relative to the lid. With a "pop" the seal jumps into the opening, where it is then cut off by moving the cap relative to the lid. An acoustic signal can also be achieved by the seal jumps into a recess in the cap and thereby indicates a specific position of the lid relative to the cap - preferably audible.

Um das Schneiden des Siegels an einer vorbestimmten Stelle zu erleichtern wird vorgesehen, dass das Siegelelement eine umlaufende Schwächung für das Eingreifen der Schneide aufweist.In order to facilitate the cutting of the seal at a predetermined location, it is provided that the sealing element has a peripheral weakening for the engagement of the cutting edge.

Besonders vorteilhaft ist es weiterhin, wenn das geöffnete Siegel einen Dichtbereich zwischen Deckel und Verschlusskappe bildet. Hierbei ist darauf zu achten, dass auch nach dem Entfernen eines Teils des Siegels zur Öffnung des Siegels noch genügend Siegelmaterial verbleibt, um eine ausreichende Abdichtung zwischen Deckel und Verschlusskappe zu ermöglichen.It is furthermore particularly advantageous if the opened seal forms a sealing area between the cover and the closure cap. It is important to ensure that even after removing a portion of the seal to the opening of the seal still enough sealing material remains to allow sufficient sealing between the lid and cap.

Um ein Verlieren eines abgeschnittenen Siegelteils zu verhindern, kann die Verschlusskappe eine Öffnung mit einer Abdeckung aufweisen. Die Abdeckung bildet dann eine Kavität zur Aufnahme zumindest eines Teils des Siegels. Diese Abdeckung kann einstückig mit der Verschlusskappe ausgebildet sein oder als Zusatzteil mit ihr verbunden sein. Hierbei kann vorzugsweise vorgesehen werden, dass die Öffnung mit der Schneide eine Abdeckung aufweist. Insbesondere bei hohen Drücken in der Verpackung wird dadurch verhindert, dass ein mit einer Öffnung in der Verschlusskappe fluchtendes Siegel sich von alleine oder unkontrolliert öffnet und Flüssigkeit herausspritzt oder ein Teil des Siegels vom Druck beschleunigt weg fliegt.To prevent loss of a cut-off seal member, the closure cap may have an opening with a cover. The cover then forms a cavity for receiving at least a portion of the seal. This cover may be integrally formed with the cap or be connected as an additional part with her. In this case, it can preferably be provided that the opening with the cutting edge has a cover. In particular, at high pressures in the package is thereby prevented that a seal aligned with an opening in the closure cap opens by itself or uncontrolled and liquid squirts or part of the seal from the pressure accelerated away flies.

Insbesondere, wenn eine spezielle Öffnung zum Abschneiden des Siegels vorgesehen ist, ist es vorteilhaft, wenn das Siegel und die Ausgussöffnung in der Verschlusskappe derart ausgebildet sind, dass das Siegel nicht in die Ausgussöffnung eindringen kann.In particular, if a special opening is provided for cutting off the seal, it is advantageous if the seal and the spout opening in the closure cap are formed such that the seal can not penetrate into the spout opening.

Um sicher zu stellen, dass die Funktionen Siegel öffnen und Verpackung entleeren in der richtigen Reihenfolge durch Bewegung der Verschlusskappe relativ zum Deckel angeboten werden, wird vorgeschlagen, dass die Verschlusskappe nur in eine Richtung relativ zum Deckel bewegbar ist.In order to ensure that the functions open seal and empty packaging in the correct order by movement of the cap relative to the lid are offered, it is proposed that the cap is movable in one direction only relative to the lid.

In der Praxis hat sich herausgestellt, dass es vorteilhaft ist, wenn der Abstand zwischen der Ausgussöffnung und einer weiteren Öffnung kleiner ist als der Durchmesser des Siegels. Dies erlaubt es, die Verschlusskappe in beliebiger Position auf den Deckel aufzusetzen.In practice, it has been found that it is advantageous if the distance between the spout opening and a further opening is smaller than the diameter of the seal. This makes it possible to put the cap in any position on the lid.

Besondere Möglichkeiten der Werbung oder auch zur Information zur Bedienung des Verpackungsverschlusses erschließen sich, wenn die Verschlusskappe eine Prägung für eine Information aufweist.Special possibilities of advertising or information to operate the packaging closure open up when the cap has an embossing for information.

Herstellungstechnisch vorteilhaft ist, wenn die Verschlusskappe aus einem Mehrkomponentenmaterial hergestellt ist. Dies erlaubt es, besonders feste Materialien zur Verbindung von Verschlusskappe und Deckel bereit zu stellen, während andere Materialqualitäten für die Dichtbereiche benötigt werden.Manufacturing technology is advantageous if the cap is made of a multi-component material. This makes it possible to provide particularly strong materials for connecting the closure cap and lid, while other material qualities are required for the sealing regions.

Eine vorteilhafte Ausführungsvariante sieht daher vor, dass die Verschlusskappe einen Metallrahmen mit einem Kunststoffeinsatz aufweist.An advantageous embodiment therefore provides that the closure cap has a metal frame with a plastic insert.

Für die Ausführungsbeispiele ist eine Elastizität des Siegelelementes notwendig somit das Siegelelement zur Anlage an die Verschlusskappe verformbar ist. Dies ermöglicht es, im geschlossenen Zustand das Siegelelement mit der Verschlusskappe abzustützen.For the embodiments, an elasticity of the sealing element is necessary thus the sealing element is deformable for engagement with the closure cap. This makes it possible to support the sealing element with the cap in the closed state.

Hierbei wird bevorzugt vorgesehen, dass das Siegelelement einen gegen die Verschlusskappe abdichtenden Rahmen aufweist.Here, it is preferably provided that the sealing element has a sealing against the closure cap frame.

Vorteilhaft ist es, wenn das Siegelelement einen Faltenbalg aufweist. Dies ermöglicht es, einen Teil des Siegelelementes auf einfache Art und Weise in die Verpackung zu drücken oder auch einen Teil des Siegelelementes beispielsweise als Ausguss zu verlängern.It is advantageous if the sealing element has a bellows. This makes it possible to press a part of the sealing element in a simple manner in the packaging or to extend a part of the sealing element, for example, as a spout.

Eine andere Ausführungsform sieht vor, dass das Siegelelement ein Filmscharnier aufweist. Ein Filmscharnier oder mehrere Filmscharniere ermöglichen das Vorsehen von Sollknickstellen, mit denen ein Faltenbalg herstellbar ist oder die eine definierte Verformung des Siegelelementes ermöglichen.Another embodiment provides that the sealing element has a film hinge. A film hinge or a plurality of film hinges allow the provision of predetermined bending points with which a bellows can be produced or which allow a defined deformation of the sealing element.

Obwohl im folgenden die Erfindung an einer runden Dose erläutert ist, sind die Merkmale der Erfindung je nach Anwendungsfall auch für eine Verpackung einsetzbar, bei der die Verschlusskappe verschiebbar ist.Although in the following the invention is explained on a round box, the features of the invention, depending on the application, can also be used for packaging in which the closure cap is displaceable.

Wie aus der Darstellung in den Figuren 1 bis 6 ersichtlich, weist eine beispielsweise in Form einer Getränkedose ausgebildete Verpackung 1 in ihrem insgesamt mit 2 bezeichneten Verschlussbereich einen Deckel 3 und eine gegenüber dem Deckel 3 verdrehbare Verschlusskappe 4 auf. Der Deckel 3 weist eine außermittige Ausgussöffnung 5 zum Entleeren des Inhalts auf. Die Verschlusskappe 4, die zwar gegenüber dem Deckel 3 verdrehbar, aber im vorliegenden Ausführungsbeispiel nicht abhebbar ist, weist ebenfalls eine außermittige Ausgussöffnung 6 auf, die in der Drehlage entsprechend Fig. 3 mit der Ausgussöffnung 5 im Deckel 3 in fluchtende Ausrichtung bringbar ist.As from the presentation in the FIGS. 1 to 6 can be seen, for example, has a formed in the form of a beverage can packaging 1 in its total designated 2 closure region a lid 3 and a relative to the lid 3 rotatable cap 4. The lid 3 has an eccentric spout opening 5 for emptying the contents. The cap 4, although rotatable relative to the cover 3, but not liftable in the present embodiment, also has an off-center spout opening 6, which in the rotational position accordingly Fig. 3 can be brought in alignment with the spout opening 5 in the lid 3.

Die Verschlusskappe 4 weist außerdem noch einen außermittigen Schließbereich 7 auf, der ebenfalls wie die Ausgussöffnung 6 außermittig angeordnet ist und in fluchtende Ausrichtung mit der Ausgussöffnung 5 im Deckel bringbar ist, wie dies aus Fig. 2 hervorgeht.The cap 4 also has an off-center closing portion 7, which is also arranged like the spout opening 6 off-center and can be brought into alignment with the spout opening 5 in the lid, as can be seen from Fig. 2 evident.

Nach dem Befüllen der Verpackung 1 wird der Deckel 3 beispielsweise durch Aufbördeln auf der Verpackung 1 befestigt. Hierbei kann die Verpackung 1, wenn es sich um Flüssigkeiten handelt, die sie aufnimmt, um einen geringen Prozentsatz überfüllt werden, so dass nach dem Aufsetzen des Deckels 3 keine Lufteinschlüsse vorhanden sind. Hierauf wird dann die Verschlusskappe 4 aufgebracht. Im unbenutzten Zustand befindet sich der Schließbereich 7 der Verschlusskappe 4 in fluchtender Ausrichtung mit der Öffnung 5 im Deckel 3, wie dies aus Fig. 2 hervorgeht.After filling the package 1, the lid 3 is fixed, for example, by flanging on the package 1. In this case, the packaging 1, when it comes to liquids that it receives, are overfilled by a small percentage, so that after placing the lid 3 no air pockets are present. Then the cap 4 is applied. In the unused state, the closing area 7 of the closure cap 4 is in alignment with the opening 5 in the lid 3, as can be seen Fig. 2 evident.

Beim Aufbringen des Deckels 3 auf der Verpackung 1 ist die Ausgussöffnung 5 mittels eines Siegelelementes 8 flüssigkeitsdicht verschlossen. Dieses Siegelelement 8 hat in dem dargestellten Ausführungsbeispiel eine nach außen gewölbte Kappenform und weist einen radial nach außen abstehenden Flansch 9 auf. Mit diesem Flansch 9 ist das Siegelelement 8 an der Innenseite des Deckels 3 beispielsweise durch Festkleben befestigt.When applying the lid 3 on the packaging 1, the spout opening 5 is sealed liquid-tight by means of a sealing element 8. This sealing element 8 has in the illustrated embodiment, an outwardly curved cap shape and has a radially outwardly projecting flange 9. With this flange 9, the sealing element 8 is fixed to the inside of the lid 3, for example by gluing.

In unbenutztem Zustand reicht das Siegelelement 8 in eine Aussparung 10 der Verschlusskappe 4 hinein, die sich im Schließbereich 7 befindet. Das Siegelelement 8 ist mit einer Handhabe 11 versehen, die nach dem Verdrehen der Verschlusskappe 4 aus der in Fig. 7 gezeigten Lage in die in Fig. 9 gezeigte Lage aus der Ausgussöffnung 6 der Verschlusskappe 4 hervortritt und ein Abreißen des Siegelelementes 8 an einer Sollbruchstelle 21 ermöglicht, die in Fig. 9 zu sehen ist.In the unused state, the sealing element 8 extends into a recess 10 of the closure cap 4, which is located in the closing region 7. The sealing element 8 is provided with a handle 11, which after the rotation of the cap 4 from the in Fig. 7 shown location in the Fig. 9 shown position from the spout opening 6 of the cap 4 emerges and allows tearing of the sealing element 8 at a predetermined breaking point 21, the in Fig. 9 you can see.

Nach dem zumindest teilweisen Entfernen des Siegelelementes 8 kann der Inhalt der Verpackung 1 entleert werden. Die Figuren 7 bis 10 zeigen den vollkommen verschlossenen Zustand im Originalzustand entsprechend Fig. 7, eine Zwischenlage entsprechend Fig. 8, die Endlage entsprechend Fig. 9 vor dem Abreißen des Siegelelementes 8 und den bereits teilweise eingerissenen Zustand entsprechend Fig. 10.After the at least partial removal of the sealing element 8, the contents of the packaging 1 can be emptied. The FIGS. 7 to 10 show the completely closed state in the original state accordingly Fig. 7 , a liner corresponding Fig. 8 , the final position accordingly Fig. 9 before tearing off the sealing element 8 and the already partially torn state accordingly Fig. 10 ,

Bei den Ausführungsbeispielen nach den Figuren 1 bis 12 weist die Verschlusskappe 4 einen einzigen mit 9 bezeichneten radial abstehenden Flansch auf, der an der Unterseite des Deckels 3 befestigt ist. Bei allen Ausführungsformen gemäß den Figuren 1 bis 12 ist sowohl der Bereich um die Ausgussöffnung 6 in der Verschlusskappe 4 als auch der Schließbereich 7 von einer Dichtung 12 bzw. 13 umgeben, um sicherzustellen, dass im geöffneten Zustand entsprechend Fig. 10 kein Produkt aus der Verpackung zwischen die Verschlusskappe 4 und den Deckel 3 gelangen kann.In the embodiments of the FIGS. 1 to 12 For example, the cap 4 has a single radially projecting flange, designated 9, which is secured to the underside of the lid 3. In all embodiments according to the FIGS. 1 to 12 is both the area around the spout opening 6 in the cap 4 and the closing portion 7 surrounded by a seal 12 and 13, respectively, to ensure that in the open state accordingly Fig. 10 no product can get out of the packaging between the cap 4 and the lid 3.

Beim Wiederverschließen gelangt der Schließbereich 7 über die Ausgussöffnung 5 des Deckels 3. Auch in diesem Zustand dichtet die Dichtung 13 den Spalt zwischen der Verschlusskappe 4 und dem Deckel 3 ab, so dass keine Flüssigkeit oder sonstige Produktteilchen zwischen die Verschlusskappe 4 und den Deckel 3 gelangen können.When re-closing the closing area 7 passes through the spout opening 5 of the lid 3. Also in this state, the seal seals 13 the gap between the cap 4 and the lid 3, so that no liquid or other product particles between the cap 4 and the cover 3 arrive can.

Bei der Ausführungsform nach Fig. 11 ist der Flansch 9 des kappenförmigen Siegelelementes 8 auf der Oberseite des Deckels 3 befestigt.In the embodiment according to Fig. 11 the flange 9 of the cap-shaped sealing element 8 is fixed on the upper side of the lid 3.

Die Ausführungsform nach Fig. 12 unterscheidet sich von allen bisher dargestellten Ausführungsformen dadurch, dass das kappenförmige Siegelelement 8 zwei Flansche 9 und 9' aufweist, die zwischen sich den Öffnungsrand des Deckels 3 aufnehmen.The embodiment according to Fig. 12 differs from all embodiments shown so far in that the cap-shaped sealing element 8 has two flanges 9 and 9 ', which receive the opening edge of the lid 3 between them.

Bei der Ausführungsform nach Fig. 13 ist der obere Flansch - mit 9" bezeichnet - wesentlich breiter und dicker ausgeführt. Hierdurch kann dieser Flansch 9" als Dichtung dienen und ersetzt somit sowohl die die Ausgussöffnung 6 in der Verschlusskappe 4 umgebende Dichtung 12 als auch die den Schließbereich 7 umgebende Dichtung 13.In the embodiment according to Fig. 13 the upper flange is markedly wider and thicker, designated 9 ", so that this flange 9" can serve as a seal and thus replaces both the gasket 12 surrounding the spout opening 6 in the closure cap 4 and the gasket 13 surrounding the closing region 7.

Damit beim Entleeren von Flüssigkeiten diese auch bei einer relativ kleinen Ausgussöffnung 5 relativ schnell entweichen kann, ist eine Entlüftungsöffnung 22 vorgesehen, die durch ein Siegelelement 14 verschlossen ist, solange sich die Verpackung in einem ungeöffneten Zustand befindet. Die Entlüftungsöffnung 22 und das Siegelelement 14 sind insbesondere aus den Figuren 4 und 5 erkennbar.Thus, when emptying liquids this can escape relatively quickly even at a relatively small spout opening 5, a vent opening 22 is provided, which is closed by a sealing member 14, as long as the package is in an unopened state. The vent opening 22 and the sealing element 14 are in particular from the FIGS. 4 and 5 recognizable.

Zum Öffnen dieser Entlüftungsöffnung 22 ist ein Vorsprung 15 an der Unterseite der Verschlusskappe 4 vorgesehen, der im verschlossenen Zustand des gesamten Schließbereiches in eine Vertiefung 16 im Deckel 3 eingreift, um ein Abheben der Verschlusskappe 4 in diesem Schließzustand zu verhindern.To open this vent opening 22, a projection 15 is provided on the underside of the closure cap 4, which engages in the closed state of the entire closing area in a recess 16 in the lid 3 to prevent lifting of the cap 4 in this closed state.

Fig. 5 zeigt den Zustand, in welchem die Entlüftungsöffnung 22 durch das Siegelelement 14 verschlossen ist. Der dem Siegelelement 14 gegenüber liegende Bereich der Verschlusskappe 4 ist von einer Dichtung 17 umgeben, die dazu dient, die Entlüftungsöffnung 22 nach dem Wiederverschließen der Verpackung 1 abzudichten, so dass über die Entlüftungsöffnung 22 keine Flüssigkeit bzw. keine Produktteilchen zwischen Deckel 3 und Verschlusskappe 4 gelangen können. Nach dem Verdrehen der Verschlusskappe 4 aus der Lage gemäß Fig. 5 in die Lage gemäß Fig. 6 dringt der Vorsprung 15 in das Siegelelement 14 ein und durchsticht dieses. Fig. 5 shows the state in which the vent opening 22 is closed by the sealing element 14. The sealing element 14 opposite region of the cap 4 is surrounded by a seal 17 which serves to seal the vent opening 22 after reclosing the package 1, so that via the vent 22 no liquid or product particles between the lid 3 and cap 4 can reach. After twisting the cap 4 from the position according to Fig. 5 according to the situation Fig. 6 penetrates the projection 15 in the sealing member 14 and pierces this.

Die Figuren 14 bis 16 zeigen eine abgewandelte Ausführungsform, die eine andere Art der Öffnung des Siegelelementes 8 ermöglicht. Fig. 14 zeigt den Zustand, in welchem der Schließbereich 7 der Verschlusskappe 4 über dem Siegelelement 8 liegt. Fig. 15 zeigt die Schnittdarstellung im Bereich der Ausgussöffnung 6 der Verschlusskappe 4, in welcher sich ein Stanzwerkzeug 18 befindet, das durch Herunterdrücken in die in Fig. 16 gezeigte Lage auf einem Teilumfang des kappenförmigen Bereiches des Siegelelementes 8 dieses durchsticht.The FIGS. 14 to 16 show a modified embodiment that allows a different type of opening of the sealing element 8. Fig. 14 shows the state in which the closing portion 7 of the cap 4 is above the sealing element 8. Fig. 15 shows the sectional view in the region of the spout opening 6 of the cap 4, in which a punching tool 18 is located, which by pressing down in the in Fig. 16 shown position on a partial circumference of the cap-shaped region of the sealing element 8 pierces this.

Hierzu ist das Stanzelement 18 über einen Teilbereich des Umfangs mit einer Schneide 23 versehen, während ein anderer Teilbereich 24 stumpf ausgeführt ist, so dass keine Durchtrennung des Siegelelementes stattfindet, wie dies aus Fig. 16 hervorgeht. Der nicht durchtrennte Teil des Siegelelementes ist so gestaltet, dass er mit Vorspannung den abgetrennten Teil nach innen in die Verpackung hineindrückt und dieser Zustand ist aus Fig. 16 ersichtlich.For this purpose, the punching element 18 is provided over a portion of the circumference with a cutting edge 23, while another portion 24 is made dull, so that no severing of the sealing element takes place, as is made Fig. 16 evident. The non-severed part of the sealing element is designed so that it pushes the separated part inwardly with bias into the package and this state is off Fig. 16 seen.

Der Vorteil dieser Ausgestaltung des Siegelelementes 8 besteht darin, dass im Falle einer Getränkedose der abgestanzte Teil nicht verschluckt werden kann, sondern, ohne den Trinkvorgang zu stören, nach innen in die Verpackung 1 hineinragt.The advantage of this embodiment of the sealing element 8 is that in the case of a beverage can, the stamped part can not be swallowed, but, without disturbing the drinking process, projects inwards into the packaging 1.

Damit die Dichtungen 12, 13 beim Verdrehen der Verschlusskappe 4 nicht zerstört werden, ist eine Hebevorrichtung vorgesehen, die an der Unterseite der Verschlusskappe 4 einen Rastnocken 19 und im zugeordneten Bereich des Deckels eine Rastmulde 20 umfasst.Thus, the seals 12, 13 are not destroyed during rotation of the cap 4, a lifting device is provided which includes a locking cam 19 and in the associated region of the lid a detent 20 on the underside of the cap.

Die geometrische Gestaltung dieser beiden Teile ist so ausgeführt, dass mit Beginn einer Drehung der Verschlusskappe 4 gegenüber dem Deckel 3 die Verschlusskappe 4 angehoben wird, wobei die Dichtungen 12 und 13 vom Deckel frei kommen. Im Falle der Ausgestaltung nach Fig. 13 kommt die Verschlusskappe 4 von dem als Dichtung dienenden Flansch 9" frei.The geometric design of these two parts is designed so that at the beginning of a rotation of the cap 4 relative to the lid 3, the cap 4 is raised, the seals 12 and 13 come free from the lid. In the case of the embodiment according to Fig. 13 comes the cap 4 from the serving as a seal flange 9 "free.

Da sich die Ausgussöffnung 6 in der Verschlusskappe 4 und der Schließbereich 7 in der Verschlusskappe 4 genau einander gegenüber liegen, erfordert es eine Drehung der Verschlusskappe 4 um 180°, damit der Rastnocken 19 wieder in die Rastmulde 20 eingreift. In der einen Stellung fluchten die Ausgussöffnungen 5 und 6 des Deckels 3 und der Verschlusskappe 4 miteinander, während in der zweiten um 180° verdrehten Stellung der Schließbereich 7 über der Öffnung 5 des Deckels 3 liegt. Aus der Darstellung in den Figuren 1 und 4 ist ersichtlich, dass die Entlüftungsöffnung 22 der Ausgussöffnung 5 im Deckel 3 nahezu gegenüberliegt, was zu einer guten Entlüftung beiträgt.Since the spout opening 6 in the cap 4 and the closing portion 7 in the cap 4 are exactly opposite each other, it requires a Rotation of the cap 4 by 180 °, so that the locking cam 19 engages again in the detent recess 20. In one position, the spout openings 5 and 6 of the cover 3 and the closure cap 4 are aligned with one another, while in the second position rotated by 180 ° the closing area 7 lies above the opening 5 of the lid 3. From the representation in the FIGS. 1 and 4 It can be seen that the vent opening 22 of the spout opening 5 in the lid 3 is almost opposite, which contributes to a good ventilation.

Die Figur 17 zeigt eine Verschlusskappe 2 mit einer Ausgussöffnung 5. Die schematische Darstellung zeigt weiterhin ein Langloch 25, an dessen einem Ende eine Schneide 26 angeordnet ist. Innerhalb des Langlochs 25 ist ein Siegelelement 27 angedeutet, das in das Langloch 25 hineinragt. Das Siegelelement 27 ist mit zwei Flanschen am Deckel 28 gehalten, während die kappenförmige Abdeckung 29 des Siegelelementes 27 in die Ebene einer Verschlusskappe 30 hineinragt. Die Verschlusskappe 30 weist an dem einen Ende des Langlochs 25 die Schneide 26 auf, die durch Verdrehen der Verschlusskappe 30 relativ zum Deckel 28 mit dem Siegelelement 27 in Eingriff gebracht werden kann. Das Siegelelement 27 hat hierzu eine umlaufende Schwächung 31, die es erleichtert, mit der Schneide 26 die Kappe 29 vom Siegelelement 27 abzutrennen.The FIG. 17 shows a cap 2 with a spout opening 5. The schematic view further shows a slot 25, at one end of a cutting edge 26 is arranged. Within the slot 25, a sealing element 27 is indicated, which protrudes into the slot 25. The sealing element 27 is held with two flanges on the cover 28, while the cap-shaped cover 29 of the sealing element 27 protrudes into the plane of a closure cap 30. The cap 30 has at one end of the slot 25, the cutting edge 26, which can be brought by rotation of the cap 30 relative to the lid 28 with the sealing element 27 in engagement. The sealing element 27 has for this purpose a circumferential weakening 31, which makes it easier to separate the cap 29 from the sealing element 27 with the cutting edge 26.

Ein weiteres Ausführungsbeispiel, bei dem eine Verschlusskappe mit einem im Deckel angeordneten Siegelelement zusammenwirkt, ist in den Figuren 20 bis 31 beschrieben.A further embodiment, in which a closure cap cooperates with a sealing element arranged in the lid, is in the FIGS. 20 to 31 described.

Die Figur 20 zeigt den Deckel 40 einer Dose 41 mit einem exzentrisch in einer Öffnung 42 des Deckels 40 angebrachten Siegelelement 43. Das Siegelelement 43 hat eine Vorspannung durch seine Formgebung, die dafür sorgt, dass eine Kappe 44 deutlich über das Niveau des Deckels 40 hervorragt.The FIG. 20 shows the lid 40 of a can 41 with an eccentrically mounted in an opening 42 of the lid 40 sealing member 43. The sealing member 43 has a bias by its shape, which ensures that a cap 44 protrudes well above the level of the lid 40.

Die Figuren 22 und 23 zeigen, wie beim Aufsetzen der Verschlusskappe 45 der Deckel 44 des Siegelelementes 43 heruntergedrückt wird. Ein flexibles Filmscharnier 46 im Siegelelement 43 ermöglicht es, das Siegelement 43 nach innen in den Doseninnenraum zu drücken, so dass der Deckel 44 des Siegelelementes 43 direkt oberhalb des Deckels 40 der Dose 41 liegt. Das Siegelelement 43 bleibt derart unter Spannung, dass es weiterhin das Bestreben hat, nach außen zu springen. Da die Verschlusskappe 45 in der aufgesetzten Position oberhalb des Siegelelementes 43 jedoch keine Öffnung hat, unterstützt die Verschlusskappe 45 das Siegelelement 43 beim Halten eines Innendrucks innerhalb der Dose 40. Dies ist insbesondere für Dosen mit kohlensäurehaltigen Getränken sehr relevant. Der obere Flansch 47 des Siegelelementes 43 dient hierbei als Abdichtung zwischen dem Deckel 40 der Dose 41 und der Verschlusskappe 45.The FIGS. 22 and 23 show how 45 is pressed down the cover 44 of the sealing element 43 when placing the cap. A flexible film hinge 46 in the sealing element 43 makes it possible to press the sealing element 43 inwards into the interior of the can, so that the cover 44 of the sealing element 43 lies directly above the cover 40 of the can 41. The sealing element 43 remains under tension in such a way that it continues to attempt to jump outward. However, because the closure cap 45 has no opening in the fitted position above the sealing member 43, the closure cap 45 assists the sealing member 43 in maintaining an internal pressure within the can 40. This is particularly relevant to cans containing carbonated beverages. The upper flange 47 of the sealing element 43 serves as a seal between the cover 40 of the can 41 and the closure cap 45.

Die Figur 23 zeigt, wie die Verschlusskappe 45 das Siegelelement 43 abdeckt.The FIG. 23 shows how the closure cap 45 covers the sealing element 43.

In den Figuren 24 bis 27 ist gezeigt, wie die Verschlusskappe 45 durch Drehen in Richtung des Pfeils 48 eine langlochartige Öffnung 49 mit einer Schneide 50 über das Siegelelement 43 schiebt. Sowie das Siegelelement 43 vollständig in das Langloch 49 eindringen kann, springt es mit einem hörbaren "Plopp" in das Langloch 49 und damit in die Wirkungsebene der Schneide 50. Der Nutzer der Getränkedose erkennt hierbei akustisch und optisch die Unversehrtheit des Siegels 43 innerhalb des Langlochs.In the FIGS. 24 to 27 It is shown how the cap 45 pushes a slot-like opening 49 with a cutting edge 50 via the sealing element 43 by rotating in the direction of the arrow 48. As the sealing element 43 can completely penetrate into the slot 49, it jumps with an audible "pop" in the slot 49 and thus in the plane of action of the blade 50. The user of the beverage can recognizes acoustically and visually the integrity of the seal 43 within the slot ,

Die Figuren 28 und 29 zeigen, wie die Schneide 50 den Deckel 44 des Siegelelements 43 abtrennt, indem sie von der Verschlusskappe 45 unter den Deckel 44 geschoben wird.The FIGS. 28 and 29 show how the cutting edge 50, the cover 44 of the sealing member 43 is separated by being pushed by the cap 45 under the cover 44.

Beim Weiterdrehen der Verschlusskappe 45 relativ zum Deckel 40 der Dose 41 wird die Kappe 44 vollständig abgetrennt und das Langloch über der Öffnung 42 im Deckel 40 hinweg gedreht. Dadurch gelangt eine Ausgussöffnung 51 in den Bereich oberhalb der Ausgussöffnung 42 im Dosendeckel 40, so dass der Inhalt der Dose durch die Ausgussöffnungen 42 und 51 heraustreten kann. Auch in dieser Position dichtet der obere Flansch 47 des Siegelelementes 43 zwischen dem Deckel 40 der Dose 41 und der Verschlusskappe 54 ab.Upon further rotation of the cap 45 relative to the lid 40 of the can 41, the cap 44 is completely separated and the slot is rotated over the opening 42 in the lid 40 away. This results in a spout opening 51 in the area above the spout opening 42 in the can lid 40, so that the contents of the can through the spouts 42 and 51 can emerge. In this position too, the upper flange 47 of the sealing element 43 seals between the cover 40 of the can 41 and the closure cap 54.

Eine spezielle Ausführungsform eines Dosenverschlusses 60 ist in der Figur 32 gezeigt. Hierbei ist auf der Dose 61 ein zweiteiliger Deckel 62 angebracht. Dieser zweiteilige Deckel 62 besteht aus einem an die Dose 61 angebördelten ringförmigen Element 63 aus Metall und einem daran mit Flanschen befestigten Innenteil 64 aus Kunststoff. In dem Innenteil 64 aus Kunststoff ist ein Siegelelement 65 ausgebildet, das mit einer Ausnehmung 66 in einer Verschlusskappe 67 zusammenwirkt und bei Verdrehen der Verschlusskappe 67 zum Deckel 62 in eine Ausgussöffnung 68 hineingeraten kann.A particular embodiment of a can closure 60 is shown in FIG FIG. 32 shown. Here, a two-piece lid 62 is mounted on the can 61. This two-part cover 62 consists of an edged to the box 61 annular member 63 made of metal and an attached thereto with flanges inner part 64 made of plastic. In the inner part 64 made of plastic, a sealing element 65 is formed, which cooperates with a recess 66 in a cap 67 and can enter into a spout opening 68 upon rotation of the cap 67 to the lid 62.

Auch bei diesem Ausführungsbeispiel kann eine Öffnung des Siegels 65 mittels einer Handhabe oder eine Schneide erfolgen.Also in this embodiment, an opening of the seal 65 can be effected by means of a handle or a cutting edge.
