Description

Die vorliegende Erfindung betrifft eine Öffnungsvorrichtung für Verpackungsbehälter, insbesondere für eine aus einer Materialbahn oder einem Materialbogen hergestellte Flüssigkeitsverpackung nach dem Oberbegriff des Patentanspruchs 1 und ein Abdeckelement für eine solche Vorrichtung nach Patentanspruch 21.The present invention relates to an opening device for packaging containers, in particular for a liquid packaging produced from a material web or a material sheet according to the preamble of patent claim 1 and a covering element for such a device according to claim 21.

Derartige Öffnungsvorrichtungen für Verpackungsbehälter sind beispielsweise aus der EP 0 658 480 A1 oder der EP 95 920 224.3 bekannt, wonach an einer insbesondere aus einer Materialbahn oder einem Materialbogen hergestellten Verpackung, die eine Öffnung beispielsweise in Form eines Loches oder einer Lochanzeige aufweist, mindestens ein Grundelement im Bereich dieser Öffnung des Behälters angebracht ist. Weiterhin weisen diese bekannten Öffnungsvorrichtungen mindestens ein Abdeckelement zum Verschließen der Öffnung auf, wobei das Abdeckelement derart am Grundelement anbringbar ist, daß die Öffnung sowohl verschlossen, als auch geöffnet werden kann.Such opening devices for packaging containers are known, for example, from EP 0 658 480 A1 or EP 95 920 224.3, according to which at least one basic element is produced on a packaging produced in particular from a material web or a material sheet which has an opening, for example in the form of a hole or a hole display is mounted in the region of this opening of the container. Furthermore, these known opening devices have at least one cover member for closing the opening, wherein the cover member is attachable to the base member such that the opening can be both closed, as well as opened.

Der bevorzugte Verpackungstyp, der aus einem Laminat hergestellt wird, das aus einem Pappe- oder Papierkern mit Thermoplastschichten und ggf. Aluminiumfolie hergestellt wird, kann aus einer kontinuierlichen Materialbahn oder aus einzelnen Rohlingen hergestellt werden. Dieser Verpackungstyp ist häufig mit einer Öffnungsvorrichtung versehen, die aus einem sogenannten Aufreißstreifen besteht, der beim Öffnen der Packung abgerissen wird. Aus der EP-A-0 558 946 ist auch bekannt, diesen Verpackungstyp mit einer äußeren Thermoplaststruktur zu versehen, die diesen Streifen umgibt. Diese Thermoplaststruktur kann mit einem Gießelement und einem Abdeckelement versehen sein, die mittels einer Scharnierfunktion übereinandergefaltet werden und gestaltungsmäßig starr ineinandergreifen können. Der meist unter dieser Thermoplaststruktur liegende Streifen besitzt häufig einen Teil, der unversiegelt und über den versiegelten Abschnitt des Streifens gefaltet ist. Dadurch ist es auf einfache Weise möglich, beim Öffnen der Packung den Streifen zu greifen und diesen zur Öffnung des Lochs oder der Lochanzeige abzureißen.The preferred type of packaging made from a laminate made from a paperboard or paper core with thermoplastic layers and optionally aluminum foil is produced, can be made of a continuous web or of individual blanks. This type of packaging is often provided with an opening device which consists of a so-called tear-strip, which is torn off when the package is opened. From EP-A-0 558 946 it is also known to provide this type of packaging with an outer thermoplastic structure surrounding this strip. This thermoplastic structure may be provided with a casting element and a cover element, which are folded over one another by means of a hinge function and can rigidly mesh in terms of design. The strip, most commonly under this thermoplastic structure, often has a portion which is unsealed and folded over the sealed portion of the strip. This makes it possible in a simple manner, when opening the pack to grab the strip and tear it off to open the hole or the hole display.

Weiterhin ist es bsp. aus der DE 44 09 946 A1 oder der DE 199 04 837 C1 bekannt, die Öffnung eines Verpackungsbehälters, der aus einer Bahn aus Verpackungsmaterial gebildet ist, die hauptsächlich aus Papier oder Kunststoffmaterial besteht, mit einer filmförmigen Folie bzw. einer aus Kunstharz bestehenden Aufreißlasche oder einer Kunststofflasche dicht zu verschließen. Zum Öffnen der Abdichtung der Öffnung wird die Folie bzw. die Aufreißlasche abgerissen bzw. wird die Folie mit einem Trinkhalm durchstochen. Die Aufreisslasche kann dabei mit der innersten Schicht des Laminats des Behälters verbunden sein, um die aseptischen Anforderungen während der Befüllung des Behälters zu erfüllen. Diese Schicht wird beim Öffnen eingerissen und dann mit der Lasche im Öffnungsbereich entfernt.Furthermore, it is bsp. DE 44 09 946 A1 or DE 199 04 837 C1 discloses the opening of a packaging container, which is formed from a web of packaging material, which consists mainly of paper or plastic material, with a film-shaped film or a tear-open tab made of synthetic resin or Close a plastic bottle tightly. To open the seal of the opening, the film or tear tab is torn off or the film is pierced with a drinking straw. The tear tab can be connected to the innermost layer of the laminate of the container to meet the aseptic requirements during the filling of the container. This layer is torn when opened and then removed with the tab in the opening area.

Schließlich ist es aus der WO 00/47480 bekannt, eine Öffnungsvorrichtung zum Öffnen der Abdichtung eines Verpackungsbehälters an einer Position für die Öffnung derart vorzusehen, daß ein Öffnungsabschnitt zum Öffnen der Abdichtung eines Abdichtteils vorgesehen ist, ein Betätigungsabschnitt zum Betätigen des Öffnungsabschnitts und ein Abstützabschnitt zum Abstützen des Betätigungsabschnitts in der Weise, daß die Vorrichtung zum Öffnen der Abdichtung an dem Verpackungsbehälter sicher befestigt ist. Der Öffnungsabschnitt kann bsp. scharnierartig nach innen zum Durchstossen der ggf. vorperforierten Öffnung verwendet werden.Finally, it is known from WO 00/47480 to provide an opening device for opening the seal of a packaging container at a position for the opening such that an opening portion for opening the seal of a sealing member is provided, an actuating portion for actuating the opening portion and a support portion for Supporting the operating portion in such a manner that the device for opening the seal is securely fastened to the packaging container. The opening section can bsp. are used inwardly to pierce the possibly pre-perforated opening.

Die vorgenannten Öffnungsvorrichtungen weisen allesamt eine an der Öffnung des Verpackungsbehälters angebrachte Thermoplaststruktur auf, die mittels eines Hot-Melt-Klebers an der Oberfläche des Behälters im Öffnungsbereich befestigt wird. Der Nachteil dieser herkömmlichen Öffnungsvorrichtungen besteht insbesondere darin, daß das Aufbringen dieser Thermoplaststrukturen meistens durch aufwendige Positioniervorrichtungen erschwert und ein Ablösen der Thermoplaststruktur während des Transports nicht immer zuverlässig vermieden werden kann.The aforesaid opening devices all have a thermoplastic structure attached to the opening of the packaging container, which is attached to the surface of the container in the opening area by means of a hot-melt adhesive. The disadvantage of these conventional opening devices is, in particular, that the application of these thermoplastic structures is often complicated by complicated positioning devices and detachment of the thermoplastic structure during transport can not always be reliably avoided.

Auch werden die Materialkanten der Öffnung des Verpackungsbehälters durch eine an der Oberfläche des Verpackungsbehälters aufgebrachten Thermoplaststruktur nicht versiegelt, so daß beim Ausgießen des Verpackungsinhaltes das Verpackungsmaterial an den Rändern der Öffnung aufweicht. Auch ist es schwierig, derartige Öffnungsanordnungen zuverlässig zu desinfizieren bzw. zu sterilisieren, bevor die Verpackung geformt und befüllt wird.Also, the material edges of the opening of the packaging container are not sealed by a thermoplastic structure applied to the surface of the packaging container, so that when the contents of the package are poured out, the packaging material softens at the edges of the opening. Also, it is difficult to reliably disinfect or sterilize such opening arrangements before the package is molded and filled.

Auch ergeben sich beim Greifen des die Öffnung verschließenden Streifens oder beim Einreißen bzw. Durchstechen des Streifens Schwierigkeiten, wenn beispiesweise der unversiegelte, umgefaltete Abschnitt aufgrund des Herstellungsvorgangs und der Behandlung in der Füllmaschine derart gegen den versiegelten Abschnitt gedrückt wird, daß er dicht dagegen anliegt und somit nicht gegriffen werden kann, oder wenn die Thermoplaststruktur aufgrund von Positionierfehlern auf den zum Abreißen gedachten Streifen geklebt wird. Auch verbleiben bei den bekannten Öffnungsvorrichtungen oftmals Streifenteile innerhalb der Ausgießöffnung, die ein ungehindertes Ausgießen des Verpackungsinhalts erschweren.Also arise when gripping the opening occlusive strip or when tearing or piercing of the strip difficulties, if, for example, the unsealed, folded Section is pressed against the sealed portion due to the manufacturing process and the treatment in the filling machine so that it is tight against it and thus can not be grasped, or if the thermoplastic structure is stuck due to positioning errors on the intended for tearing strip. Also remain in the known opening devices often strip parts within the pouring opening, which hinder unimpeded pouring the contents of the package.

Die JP 09 254 967 offenbart eine Öffnungsvorrichtung, die mit dem Basisteil an der Innenseite der Verpackung im Bereich der Öffnung verklebt ist.JP 09 254 967 discloses an opening device, which is glued to the base part on the inside of the package in the region of the opening.

Die Erfindung löst die Aufgabe durch die kennzeichnenden Merkmale des Patentanspruches 1. Vorteilhafte Ausführungsformen der Erfindung sind in den Unteransprüchen gekennzeichnet und näher erläutert. Ein Abdeckelement für eine erfindungsgemässe Vorrichtung ist im Anspruch 21 gekennzeichnet.The invention solves the problem by the characterizing features of claim 1. Advantageous embodiments of the invention are characterized in the subclaims and explained in more detail. A cover for a device according to the invention is characterized in claim 21.

Die erfindungsgemäße Öffnungsvorrichtung für Verpackungsbehälter, die insbesondere aus einem Laminat mit einem Kern aus Papier oder Pappe hergestellt sind, an den Thermoplastschichten und ggf. Aluminium laminiert sind und die meist aus einer kontinuierlichen Materialbahn hergestellt sind, aber auch aus einzelnen Materialbögen bestehen können, weist mindestens ein Grundelement auf, das an einer Öffnung des Verpackungsbehälters angebracht ist, wobei die Öffnung in der Materialbahn oder dem Materialbogen beispielsweise durch Stanzen vorgefertigt wurde.The opening device according to the invention for packaging containers, which are in particular made of a laminate with a core of paper or cardboard, laminated to the thermoplastic layers and possibly aluminum and which are usually made of a continuous material web, but may also consist of individual sheets of material, has at least a base element which is attached to an opening of the packaging container, wherein the opening in the material web or the material sheet was prefabricated, for example by punching.

Ein Abdeckelement, das zum Verschließen oder Abdecken der Öffnung verwendbar ist, ist derart am Grundelement anbringbar, daß die Öffnung abgedeckt oder verschlossen wird. Dabei erfüllt das Abdeckelement nach der Erfindung eine Doppelfunktion: Das Abdeckelement weist einerseits Verbindungsmittel zur Verbindung des Abdeckelements mit dem Grundelement nach dem Anbringen des Grundelements am Behälter und andererseits Funktionsmittel zur Ausübung einer vorbestimmbaren Funktion auf. Insbesondere weist das Abdeckelement Schnapp-, Rast-, Klemm-, Scharnier- oder Schraubverbindungsmittel zur Verbindung mit dem Grundelement auf.A cover member, which is usable for closing or covering the opening, is attachable to the base member so that the opening is covered or closed. In this case, the cover according to the invention fulfills a dual function: the cover has on the one hand connecting means for connecting the cover with the base element after attaching the base member to the container and on the other hand functional means for performing a predeterminable function. In particular, the cover member has snap, detent, clamp, hinge or screw connection means for connection to the base member.

Das Abdeckelement hat einen Basisteil, wobei das Basisteil mit Vorteil mittels einer Schnapp-, Rast-, Klemm- oder Schraubverbindung mit dem Grundelement (1) verbindbar ist. Als Funktionsmittel hat das Abdeckelement einen Verschlußteil, das zum Verschliessen der Verpackung dient und das bsp. mittels einer Schnapp-, Rast-, Klemm-, Scharnier- oder Schraubverbindung mit dem Basisteil des Abdeckelements verbindbar ist.The cover has a base part, wherein the base part with advantage by means of a snap, latching, clamping or screw connection with the base element (1) is connectable. As a functional means, the cover has a closure part, which serves to seal the packaging and the bsp. is connectable by means of a snap, latching, clamping, hinge or screw connection with the base part of the cover.

Das Abdeckelement kann separat hergestellt und montiert werden und kann, je nach Anwendungswunsch, unterschiedlich geformt sein und unterschiedliche Aufgaben erfüllen. Während die Verpackung mit dem Grundelement vollständig gefüllt, gefaltet und verpackungs- bzw. distributionsfertig hergestellt werden kann, wird das Abdeckelement mit Vorteil erst in einem zweiten Herstellungsschritt angebracht.The cover can be manufactured and assembled separately and can, depending on the application, be shaped differently and fulfill different tasks. While the packaging with the basic element are completely filled, folded and ready for packaging or distribution can, the cover is advantageously mounted only in a second manufacturing step.

Das Abdeckelement kann als Funktionsmittel einen Verschlußteil zum Wiederverschließen der Öffnung, einen Schutzteil zum Schützen des Grundelements vor Beschädigungen durch den Transport der Verpackung oder bsp. auch ein Garantiesiegel aufweisen, das beim erstmaligen Öffnen des Verpackungsbehälters irreversibel veränderbar ist, bzw. zerstört wird, so dass eineindeutig feststellbar ist, ob Dritte die Verpackung zuvor schon geöffnet haben. Es sind aber auch andere Funktionen realisierbar, wie z.B. die Anbringung von Verbraucherinformationen auf Papier unterhalb des Verschlußteils, Aufkleber, Figuren für Kinder eine Kombination der vorerwähnten Funktionen.The cover may function as a closure member for reclosing the opening, a protective part for protecting the base member from damage caused by the transport of the package or bsp. also have a warranty seal that is irreversibly changed when you first open the packaging container, or is destroyed, so that it is uniquely determined whether third parties have already opened the package before. But there are also other functions feasible, such. the attachment of consumer information on paper below the closure, stickers, children's figures a combination of the aforementioned functions.

Statt den herkömmlichen Streifen oder Membranen zum Versiegeln der Öffnung des Verpackungsbehälters weist das Grundelement der erfindungsgemäßen Öffnungsvorrichtung mit Vorteil ein Öffnungselement auf, das zum Öffnen des Behälters entfernbar ist und das vor dem Öffnen des Behälters mit dem Grundelement verbunden ist. Mit Vorteil wird sowohl das Grundelement als auch das Öffnungselement aus einer gemeinsamen Thermoplaststruktur geformt oder gespritzt, so daß eine Trennung zwischen Grundelement und Öffnungselement erst beim erstmaligen Öffnen des Behälters durch die Entfernung des Öffnungselements vom Grundelement stattfindet.Instead of the conventional strips or membranes for sealing the opening of the packaging container, the base element of the opening device according to the invention advantageously has an opening element, which is removable for opening the container and which is connected to the base element before opening the container. Advantageously, both the base element and the opening element is molded or sprayed from a common thermoplastic structure, so that a separation between the base element and opening element only takes place when first opening the container by the removal of the opening element from the base element.

Das Grundelement ist dabei nach einer bevorzugten Ausführungsform der Erfindung derart am Randbereich der Öffnung des Verpackungsbehälters befestigt, daß es diesen Randbereich außerhalb und/oder innerhalb des Behälters vollständig umgibt und somit die Verpackungsmaterialkanten im Öffnungsbereich, insbesondere auf der Innenseite des Behälters, versiegelt.The basic element is attached according to a preferred embodiment of the invention in such a way at the edge region of the opening of the packaging container, that it completely surrounds this edge region outside and / or inside the container and thus seals the packaging material edges in the opening region, in particular on the inside of the container.

Durch die mit Vorteil vorgesehene vollständige Einfassung der Laminatkanten des Verpackungsbehälters wird ein Eindringen von beispielsweise einer sich im Behälter befindlichen Flüssigkeit in das Laminat und somit ein Aufweichen der Materialkanten im Bereich der Öffnung verhindert. Gleichzeitig kann das Grundelement der erfindungsgemäßen Öffnungsvorrichtung sicher und fest an dem Verpackungsbehälter befestigt werden, so daß ein Abreißen der Öffnungsvorrichtung während des Formens, Faltens und Befüllens des Behälters sowie während des Vertriebs und beim Endverbraucher vermieden wird.The advantageously provided complete enclosure of the laminate edges of the packaging container prevents penetration of, for example, a liquid in the container into the laminate and thus softening of the material edges in the region of the opening. At the same time the basic element of the opening device according to the invention can be securely and firmly attached to the packaging container, so that tearing of the opening device during molding, folding and filling of the container and during distribution and the end user is avoided.

Das Grundelement besteht dabei beispielsweise aus einem spritzfähigen Kunststoff, der im Spritzverfahren um den Randbereich der Öffnung zur Versiegelung der Kanten des Behältermaterials herum spritzbar ist. Diese sogenannte DIM-Technologie (Direct Injection Molded) ermöglicht die schnelle und kostengünstige Herstellung des Grundelements, das dadurch fest und unverrückbar um die Öffnung des Verpackungsbehälters herum gespritzt und mit Vorteil in einem Arbeitsvorgang auch gleich mit dem Öffnungselement sowie ggf. weiteren Teilen des Grundelements hergestellt wird.The basic element consists, for example, of a sprayable plastic which can be sprayed around the edge area of the opening in order to seal the edges of the container material. This so-called DIM technology (Direct Injection Molded) allows the fast and cost-effective production of the basic element, which thereby firmly and immovably injected around the opening of the packaging container around and made with advantage in a single operation even with the opening element and possibly other parts of the base element becomes.

Die erfindungsgemäße Öffnungsvorrichtung weist weiterhin ein Abdeckelement auf, welches separat herstellbar ist. Durch die Trennung von Grundelement und Abdeckelement wird gleichzeitig auch eine Funktionstrennung der Öffnungsvorrichtung erreicht. So lassen sich sowohl für das Grundelement als auch für das Abdeckelement verschiedene Materialien verwenden, die dem jeweiligen Einsatzzweck besonders angepaßt werden.The opening device according to the invention further comprises a cover, which can be produced separately. Due to the separation of the base element and the cover element, a functional separation of the opening device is simultaneously achieved. Thus, different materials can be used for both the base element and the cover element, which are particularly adapted to the particular application.

Das Abdeckelement ist nach einer ersten vorteilhaften Variante der vorliegenden Erfindung beispielsweise einteilig ausgeführt und wird mittels einer Schnapp-, Rast-, Klemm-, Scharnier- oder Schraubverbindung mit dem Grundelement verbunden. Nach einer weiteren vorteilhaften Ausführungsform der vorliegenden Erfindung wird das Abdeckelement zweiteilig mit einem Verschlußteil und einem Basisteil ausgebildet, wobei das Basisteil mittels einer Schnapp-, Rast-, Klemm- oder Schraubverbindung mit dem Grundelement verbindbar ist und das Schließen bzw. Öffnen durch das Verschlußteil durchgeführt wird, welches als Deckel-, Schraub- oder Bayonettverschlußteil ausführbar ist. Auch kann das Verschlußteil je nach Ausführungsform mittels einer Schnapp-, Rast-, Klemm-, Scharnier- oder Schraubverbindung mit dem Basisteil des Abdeckelements verbunden werden.The cover is designed according to a first advantageous variant of the present invention, for example, in one piece and is connected by means of a snap, latching, clamping, hinge or screw with the base element. To According to a further advantageous embodiment of the present invention, the cover is formed in two parts with a closure member and a base member, wherein the base member is connected by means of a snap, latching, clamping or screw connection with the base member and the closing or opening is performed by the closure member , which is executable as a lid, screw or Bayonettverschlußteil. Also, the closure member may be connected depending on the embodiment by means of a snap, detent, clamp, hinge or screw with the base part of the cover.

Die Erfindung offenbart somit in vorteilhafter Weise ein Abdeckelement bzw. ein Verschlußteil des Abdeckelements, welches austauschbar, d.h. insbesondere vom Grundelement bzw. vom Basisteil des Grundelements abnehmbar gestaltet ist. Somit lassen sich Öffnungsvorrichtungen herstellen, die mit einem einheitlichen Grundelement ausgestattet sind, während sich je nach Ausführungsform der Verpackung bzw. Anwendungsbereich beim Abnehmer der Verpackung verschiedene Abdeckelemente ausführen lassen, die mittels einer genormten Verbindung mit ein- und demselben Grundelement verbindbar sind. Der Behälter ist somit durch das Grundelement verschlossen und versiegelt und kann mit Hilfe des Öffnungselements des Grundelements erstmals geöffnet werden. Das Wiederverschließen der Verpackung kann dann je nach Anwendungsform mittels eines als Schraubverschluss, mittels eines als Deckel, mittels eines als Bayonettverschluss oder beispielsweise auch mittels eines als Klappverschluss gestaltetes Abdeckelement ausgeführt werden.The invention thus advantageously discloses a cover element or a closure part of the cover element which is exchangeable, i. is designed in particular removable from the base element or from the base part of the base element. Thus, opening devices can be produced, which are equipped with a uniform base element, while depending on the embodiment of the packaging or field of application at the customer of the package various cover elements can be performed, which can be connected by means of a standardized connection with one and the same basic element. The container is thus closed and sealed by the base element and can be opened by means of the opening element of the base element for the first time. The resealing of the packaging can then be carried out depending on the application form by means of a screw cap, by means of a lid, by means of a Bayonettverschluss or for example by means of a designed as a flap cover.

Durch die Zweiteilung des Abdeckelements lassen sich je nach verwendetem Grundelement genormte Basisteile als Verbindungsmittel herstellen, die fest mit dem Grundelement verbindbar sind, während die Funktionsmittel unterschiedlich ausgestaltet, geformt oder farblich gestaltet werden können.Due to the division of the cover, it is possible, depending on the basic element used, to produce standardized base parts as connection means, which can be firmly connected to the base element are, while the functional means can be designed differently, shaped or colored.

Nach einer anderen Ausführungsform der Erfindung kann auch auf den Basisteil verzichtet werden, wenn das Verschlußteil beispielsweise mittels einer Schraubverbindung oder eines Scharniers direkt mit einer entsprechenden Aufnahme wie beispielsweise einem Gewinde oder einer Scharnierhalterung des Grundelements verbunden wird.According to another embodiment of the invention can also be dispensed with the base part, when the closure member is connected for example by means of a screw or a hinge directly to a corresponding receptacle such as a thread or a hinge bracket of the base member.

Nach einer vorteilhaften Variante der Erfindung weist das Öffnungselement einen Öffnungsabschnitt auf, der mit dem Öffnungselement verbunden ist, wobei das Öffnungselement mittels des Öffnungsabschnitts zum Öffnen des Behälters entfernbar ist und wobei das Öffnungselement insbesondere an den Verbindungsstellen zum Grundelement mit Schwächungen bzw. Sollbruchstellen versehen ist. Der Öffnungsabschnitt kann dabei aus einer Zuglasche bestehen, mit Hilfe derer das beispielsweise als Membran ausgeführte Öffnungselement abgezogen bzw. abgerissen werden kann.According to an advantageous variant of the invention, the opening element has an opening portion which is connected to the opening element, wherein the opening element is removable by means of the opening portion for opening the container and wherein the opening element is provided in particular at the connection points to the base element with weakenings or predetermined breaking points. The opening portion may consist of a pull tab, with the aid of which, for example, designed as a membrane opening element can be deducted or demolished.

Mit Vorteil ist der Öffnungsabschnitt zusätzlich mit einem Verbindungssteg mit einer Belüftungsstelle des Öffnungselements verbunden, wobei der Verbindungssteg die Belüftungsstelle beim Betätigen des Öffnungsabschnitts und noch vor dem Entfernen des Öffnungselements selbst öffnet. Durch die Öffnung der Belüftungsstelle kann vor dem eigentlichen Öffnen der Öffnung des Verpackungsbehälters Luft in den Verpackungsbehälter eindringen, so daß der Produktlevel des Verpackungsinhalts sinkt und ein ungewolltes Ausschütten oder Überschütten des Verpackungsinhalts beim Öffnen des Öffnungselements verhindert wird. Die Belüftungsstelle ist beispielsweise eine Materialschwächung oder dünne Membran des Öffnungselements und im Bereich des Verbindungsstegs mit dem Verbindungssteg verbunden, so daß beim Betätigen des Öffnungsabschnitts die dünne Membran oder das an dieser Stelle geschwächte Material des Öffnungselements aufgerissen wird, so daß Luft in den Verpackungsbehälter eindringen kann.Advantageously, the opening portion is additionally connected to a connecting web with a venting point of the opening element, wherein the connecting web opens the venting point upon actuation of the opening portion and before the removal of the opening element itself. Through the opening of the ventilation point can penetrate into the packaging container prior to the actual opening of the opening of the packaging container, so that the product level of the packaging contents decreases and accidental dumping or overflowing of the contents of the package when opening the opening element is prevented. The ventilation point is, for example, a material weakening or thin membrane of the opening element and in the region of the connecting web with the connecting web connected so that upon actuation of the opening portion, the thin membrane or weakened at this point material of the opening element is torn so that air can penetrate into the packaging container.

Beim Anbringen des Abdeckelements auf dem Grundelement sind verschiedene Mittel zum Abdichten des Abdeckelements bzw. des Basisteils des Abdeckelements, im Falle einer zweiteiligen Ausführung des Abdeckelements, vorgesehen. Diese Dichtelemente können im Falle einer Schraubverbindung beispielsweise Dichtlippen am unteren Ende des mit einem Innengewinde versehenen Zylinders des Abdeckelements sein, die beim Aufdrehen des Abdeckelements auf das Grundelement gegen die Grundfläche des Grundelements stoßen, die den Randbereich der Öffnung umgibt, um so die Öffnung abzudichten. Im Falle der Ausführung des Abdeckelements als Deckel kann dieser Deckel ebenfalls an entsprechenden in Richtung des Grundelements hervorstehenden Stegen oder Rändern mit Dichtmitteln versehen sein, die beim Anklappen des Deckels mit entsprechenden Flächen bzw. Teilen des Grundelements die Öffnung abdichten.When attaching the cover on the base element, various means for sealing the cover or the base part of the cover, in the case of a two-part design of the cover, are provided. In the case of a screw connection, these sealing elements may, for example, be sealing lips at the lower end of the internally threaded cylinder of the covering element which, when the covering element is screwed onto the base element, abuts against the base surface of the base element which surrounds the edge region of the opening so as to seal the opening. In the case of the execution of the cover as a lid, this cover may also be provided on corresponding projecting in the direction of the base webs or edges with sealing means which seal the mouth when folding the lid with corresponding surfaces or parts of the base element.

Mit Vorteil ist das Abdeckelement bzw. das Basisteil des Abdeckelements mit einem Gießelement als weiteres Funktionsmittel zum Ausgießen von gießfähigen Verpackungsinhalten an der Randseite der Verpackung, an welcher sich die Öffnung vorteilhafterweise befindet, ausgestattet. Auch kann das Abdeckelement mit einem Ansatz an dieser Seite versehen sein, um das Abdeckelement greifen und öffnen zu können.Advantageously, the cover or the base part of the cover is equipped with a casting element as a further functional means for pouring pourable packaging contents on the edge side of the package, on which the opening is advantageously located. Also, the cover may be provided with a lug on this side to grab the cover and open.

Das Abdeckelement bzw. das Verschlußteil und das Basisteil ist mit Vorteil aus einem härteren Kunststoff, wie beispielsweise Polypropylen, hergestellt, während das Grundelement bzw. das Öffnungselement aus einem weicheren ggf. spritzfähigen Kunststoff, wie beispielsweise Polyethylen, besteht.The cover element or the closure part and the base part is advantageously made of a harder plastic, such as polypropylene, while the base element or the opening element of a softer possibly sprayable plastic, such as polyethylene.

Figur 6 zeigt eine bevorzugte Ausführungsform des Abdeckelements 2, welches zweiteilig mit Verschlußteil 3a und Basisteil 3b ausgeführt ist. Sowohl Verschlußteil 3a als auch Basisteil 3b sind mittels eines scharnierartigen Abschnitts 8 miteinander verbunden, während das Basisteil 3b das als nach innen abstehender und als umlaufender Rand ausgebildete Rastelement 15 zum Einrasten am Grundelement 1 aufweist.Figure 6 shows a preferred embodiment of the cover 2, which is designed in two parts with closure part 3a and base 3b. Both closure part 3a and base part 3b are connected to one another by means of a hinge-like section 8, while the base part 3b has the detent element 15 which projects as an inwardly projecting and peripheral edge for latching onto the base element 1.

Aufgrund der erfindungsgemäßen Öffnungsvorrichtung kann auf Heißkleber zum Aufbringen des Grundelements 1 verzichtet werden. Auch ist das Herstellungsverfahren sehr einfach auszugestalten, da das Abdeckelement 2 mittels eines einfachen Applikators auf das Grundelement 1 "aufklickbar" ist. Auch die Positionierung des Abdeckelements 2 ist mit Hilfe der Schnappverbindung einfach realisierbar.Due to the opening device according to the invention can be dispensed with hot glue for applying the base member 1. Also, the manufacturing process is very simple to design, since the cover 2 by means of a simple applicator on the base element 1 "clickable" is. The positioning of the cover 2 can be easily realized with the help of the snap connection.

Durch die eingearbeiteten Sollbruchstellen bzw. Schwächungen 19 im Öffnungselement 1a sind die zum Öffnen der Öffnungsvorrichtung notwendigen Kräfte sehr gering, so daß die Verpackung kaum belastet wird und ein Ausschütten des Verpackungsinhalts beim Öffnen vermieden wird. Auch weist die erfindungsgemäße Vorrichtung ein günstiges geometrisches Verhältnis zwischen den äußeren geometrischen Abmessungen des Grundelements 1 und des Abdeckelements 2 und der Nettofläche der Ausgießöffnung auf, da nahezu die gesamte Grundfläche des Grundelements 1 als Ausgießöffnung realisierbar ist. Eine geringe Gesamthöhe der Öffnungsvorrichtung von zwischen 3,5 mm bis 7,5 mm, im gezeigten Ausführungsbeispiel etwa 5,8 mm, ist realisierbar, so daß die Herstellung, der Transport und die Logistik entsprechender Verpackungen einfach gestaltbar ist.Due to the incorporated predetermined breaking points or weakening 19 in the opening element 1a, the forces required to open the opening device are very low, so that the packaging is hardly loaded and a pouring the contents of the package is avoided when opening. Also, the device according to the invention has a favorable geometric relationship between the outer geometric dimensions of the base member 1 and the cover 2 and the net surface of the pouring, since almost the entire base surface of the base member 1 can be realized as a pouring opening. A small overall height of the opening device of between 3.5 mm to 7.5 mm, shown Embodiment about 5.8 mm, is feasible, so that the production, transportation and logistics of appropriate packaging is easy to design.

Durch die funktionelle, technische und marketingstrategische Funktionstrennung zwischen Grundelement 1 und Abdeckelement 2 kann das Grundelement 1 als Öffnungslösung beispielsweise mit einem technisch bestimmten Design flach und einfach ausgeführt werden, wodurch sich gut spritzfähige geometrische Formen herstellen lassen, die für die DIM-Technologie geeignet sind.Due to the functional, technical and marketing strategic separation of functions between primitive 1 and cover 2, the primitive element 1 can be designed as opening solution, for example, with a technically specific design flat and simple, which can be produced good sprayable geometric shapes that are suitable for DIM technology.

Auf der anderen Seite kann das Abdeckelement 2 eine komplexere, ästhetisch bestimmte geometrische Form bzw. Design aufweisen und es können verschiedene Schraub-, Schnapp-, Klick- oder Bayonettverschlüsse realisiert werden, die sich durch unterschiedliche Farben gestalten lassen. Dadurch ist ein und dasselbe Grundelement für die unterschiedlichsten Anwendungsfälle, je nach verwendetem Abdeckelement, einsetzbar.On the other hand, the cover member 2 may have a more complex, aesthetically determined geometric shape or design, and various screw, snap, click or Bayonettverschlüsse can be realized, which can be designed by different colors. As a result, one and the same basic element for a variety of applications, depending on the cover used, can be used.
