Abstract

The lid element (1) for closure of a container (7) consists of two layers (2, 3) joined to one another by a cold-sealable material (4) whose adhesion is weaker than the adhesion of a hot-sealable material on the other side of the inner layer.

Description

Die Erfindung betrifft ein deckelförmig ausgestanztes Element zum Verschließen von Behältern bestehend aus einer ersten äußeren Lage und einer zweiten inneren Lage, welche an ihrer dem Behälter zugewandten Seite mit einer heißsiegelbaren Schicht versehen ist.The invention relates to a lid-shaped punched-out element for closing of containers consisting of a first outer layer and a second inner layer which faces at its the container Side is provided with a heat-sealable layer.

Es ist bekannt, zweilagige Deckel zum Verschließen von Behältern einzusetzen, um beispielsweise den für Lebensmittel geforderten Aromaschutz zu ermöglichen.It is known to use two-layer lids for closing containers, for example, the flavor protection required for food to enable.

Weiters hat es sich gezeigt, dass insbesondere im Fall von verderblichen Lebensmitteln beim Konsumenten erhöhter Informationsbedarf betreffend Herkunft, Inhaltsstoffe sowie Haltbarkeit besteht. Um für diese Informationen ausreichend Raum zu schaffen, ist man dazu übergegangen, diese auf der äußeren Lage des Verschlussdeckels aufzudrucken, wogegen die innere Lage so weit als möglich unbedruckt bleibt. Dies auch deshalb, da ein möglicher Kontakt von Druckfarben mit den Lebensmitteln vermieden werden soll.Furthermore, it has been shown that, especially in the case of perishable Foods in the consumer increased information needs regarding Origin, ingredients and durability. In order for this information to create enough space, one has gone over to this aufschudrucken on the outer layer of the closure lid, whereas the inner layer remains unprinted as far as possible. This also because, a possible contact of printing inks with the food avoided shall be.

Zum Öffnen dieser Packungen wird die obere Lage des Deckels abgezogen und erst nach dem Abtrennen der inneren, zweiten Lage ist der Zugriff zum Packungsgut möglich.To open these packages, the upper layer of the lid is removed and only after the separation of the inner, second layer is the access possible for packaged goods.

Bekannte Lösungen zeigen jedoch den Nachteil, dass dieser partielle Öffnungsvorgang manchmal schwer möglich ist, da mitunter der gesamte Deckel, also beide Lagen, vom Behälter abgezogen werden. Dies ist jedoch dann unerwünscht, wenn der Aromaschutz für das Packungsgut durch die zweite innere Lage weiter erhalten bleiben soll. Dies ist beispielsweise bei größeren Packungsinhalten, welche nur in Portionen konsumiert werden können, jedoch auch bei Packungen für Mikrowellengerichte, erforderlich.However, known solutions show the disadvantage that this partial Opening process is sometimes difficult, since sometimes the entire Cover, so both layers are deducted from the container. This is however then undesirable if the aroma protection for the packaged by the second inner situation is to be maintained. This is for example for larger package contents, which are consumed only in portions may be required, but also in microwaveable packaging.

Der vorliegenden Erfindung liegt daher die Aufgabe zu Grunde, ein dekkelförmig ausgestanztes Element der eingangs genannten Art anzugeben, welches den Packungsinhalt zufriedenstellend konserviert, insbesondere was den Aromaschutz anbelangt, und welches in einem für den Konsumenten beim Öffnen leicht handhabbar ist.The present invention is therefore based on the object, a dekkelförmig To specify punched element of the type mentioned, which satisfactorily preserves the contents of the package, in particular as far as the aroma protection is concerned, and which in one for the consumer easy to handle when opening.

Erfindungsgemäß wird diese Aufgabe mit einem deckelförmig ausgestanzten Element gelöst, welches dadurch gekennzeichnet ist, dass dessen Lagen über ihre einander zugewandten Oberflächenseiten durch eine kaltsiegelnde Schicht miteinander verbunden sind, und dass die Verbundhaftung zwischen den Lagen niedriger ist als jene zwischen der inneren Lage und dem Behälterrand.According to the invention, this object is stamped with a lid-shaped Element solved, which is characterized in that its layers over their mutually facing surface sides by a cold-sealing Layer are interconnected, and that the composite adhesion between the layers is lower than that between the inner layer and the container edge.

Durch diese unterschiedliche Verbundhaftung ist es dem Konsumenten möglich, in einfacher Weise eine partielle Öffnung des Behälters derart zu bewirken, dass in einem ersten Öffnungsschritt die äußere Lage von der dem Behälter zugewandten inneren Lage abgezogen, d.h. gepeelt wird. In einem zweiten Schritt wird die innere Lage vom Behälterrand abgezogen, wobei eine erhöhte Kraft erforderlich ist, da die heißsiegelbare Beschichtung stärker am Behälterrand haftet, als die kaltsiegende Schicht zwischen den einzelnen Verbundlagen.Due to this different bond adhesion it is the consumer possible, in a simple manner, a partial opening of the container in such a way to cause, in a first opening step, the outer layer of the inner layer facing the container, i. is peeled. In a second step, the inner layer is subtracted from the edge of the container, wherein an increased force is required because the heat-sealable Coating stronger adheres to the edge of the container, as the kaltsiegende Layer between the individual composite layers.

Weitere Ausgestaltungen des erfindungsgemäßen, deckelförmig ausgestanzten Elementes sind gemäß Unteransprüche geoffenbart.Further embodiments of the invention, punched punched out Elements are disclosed in the subclaims.

Die Erfindung wird im folgenden anhand möglicher Ausführungsformen der Erfindung näher erläutert. Dabei zeigt Fig. 1 eine mögliche Ausführungsform , worin die dem Behälter zugewandte Lage des deckelförmig ausgestanzten Elementes eine in sich geschlossene Oberfläche aufweist. Gemäß Fig. 2 ist diese Oberfläche mit Sollbruchstellen, gemäß Fig. 3 mit Perforationen zur Ausbildung einer Ausgießöffnung ausgestattet. Gemäß Fig. 4 ist die innere Lage des deckelförmig ausgestanzten Elementes in Form eines Gitters ausgebildet.The invention will be described below with reference to possible embodiments of the Invention explained in more detail. 1 shows a possible embodiment in which the container facing the position of the lid-shaped stamped element has a self-contained surface. According to Fig. 2, this surface with predetermined breaking points, as shown in FIG. 3 with Perforations equipped to form a pouring opening. According to Fig. 4 is the inner layer of the lid-shaped punched element in Formed a grid.

Bei der Herstellung des erfindungsgemäßen deckelförmig ausgestanzten Elementes 1 wird vorerst die äußere Lage 2 bzw. die innere Lage 3 hergestellt.In the production of the lid-shaped punched according to the invention Element 1, the outer layer 2 or the inner layer 3 is initially produced.

Für die Herstellung der äußeren Lage 2 wird beispielsweise eine Aluminiumfolie, deren Dicke in einem Bereich von 10 bis 100 µm liegt, verwendet. Es ist jedoch auch möglich, Kunststofffolien in einem Dickenbereich von 10 bis 100 µm einzusetzen. Die Kunststoffe können dabei aus der Gruppe Polypropylen, Polyethylen, Polyester, Polyacrylat, Polyamid oder Polystyrol ausgewählt werden.For the production of the outer layer 2, for example, an aluminum foil, the thickness of which is in a range of 10 to 100 μm. However, it is also possible to use plastic films in a thickness range from 10 to 100 μm. The plastics can from the Group polypropylene, polyethylene, polyester, polyacrylate, polyamide or Polystyrene can be selected.

Die äußere Lage 2 kann weiters an ihrer dem Betrachter zugewandten Oberflächenseite mit einem Druckbild ausgestattet werden. Dieses kann in seiner Oberflächenausgestaltung sowohl glatt als auch rau sein. Die Oberflächenrauigkeit ergibt durch unregelmäßige, aber auch regelmäßige Anordnung der Druckmotive das gewünschte Druckbild. Weiters erleichtert die Oberflächenrauigkeit des Druckbildes das Entstapeln der üblicherweise in Magazinen übereinander aufbewahrten deckelförmig ausgestanzten Elemente. The outer layer 2 can further on their facing the viewer Surface side be equipped with a printed image. This can be in Its surface design can be both smooth and rough. The Surface roughness results from irregular, but also regular Arrangement of the print motifs the desired print image. Furthermore, relieved the surface roughness of the printed image destacking the usually in magazines stacked lid-shaped punched out Elements.

Das vorgenannte Druckbild kann jedoch auch jene Informationen wiedergeben, aus welchen der Konsument die Herkunft, Zusammensetzung und Dauer der Haltbarkeit des Packungsguts entnimmt.However, the aforementioned print image can also reproduce that information from which the consumer's origin, composition and duration the durability of the packaged goods takes.

Nach dem Bedrucken der äußeren Lage 2 wird diese an ihrer Oberflächenseite 2' mit einer kaltsiegelnden Schicht 4 versehen. Kaltsiegelnde Stoffe zeichnen sich dadurch aus, dass durch Anwendung von Druck, jedoch ohne zusätzliche Temperaturanwendung eine Verbundhaftung zwischen zwei Lagen hergestellt werden kann. Die kaltsiegelnde Schicht kann beispielsweise durch Auftragen einer polymerhältigen Emulsion oder Dispersion bereitgestellt werden. Als polymerhältige Emulsionen in wässriger Form können beispielsweise solche mit der Handelsbezeichnung "Crodaseal 22-055" eingesetzt werden, da diese den lebensmittelrechtlichen Bestimmungen entsprechen. Weiters ist es denkbar, eine ebenso lebensmittelverträgliche, weichmacherfreie Polymerdispersion auf Basis von Acrylsäureestercopolymeren in Wasser mit der Handelsbezeichnung "Flexbond®" AF75 einzusetzen.After printing the outer layer 2, this is on its surface side 2 'provided with a cold-sealing layer 4. cold-sealing Substances are characterized by the fact that by applying pressure, however without additional temperature application a bond between two Layers can be made. The cold-sealing layer may, for example by applying a polymer-containing emulsion or dispersion to be provided. As polymer-containing emulsions in aqueous form For example, those with the trade designation "Crodaseal 22-055" be used, since these are the food law provisions correspond. Furthermore, it is conceivable, an equally food-compatible, plasticizer-free polymer dispersion based on acrylic acid ester copolymers in water under the trade designation "Flexbond®" AF75 use.

Unabhängig vom vorgenannten Herstellungs- bzw. Kaschiervorgang der äußeren Lage 2 wird in einem weiteren Verfahrensschritt die dem Behälter zugewandte Lage 3 hergestellt bzw. vorbereitet. Diese besteht beispielsweise aus Kunststoffen in Mono- oder Verbundstruktur, wobei ein Dickenbereich von 10 bis 100 µm ausgewählt wird. Die Kunststoffe können dabei aus der Gruppe Polypropylen, Polyethylen, Polyester, Polyacrylat, Polyamid oder Polystyrol ausgewählt werden.Regardless of the aforementioned manufacturing or laminating the outer layer 2 is in a further process step, the container facing layer 3 prepared or prepared. This consists for example of plastics in mono- or composite structure, one thickness range from 10 to 100 microns is selected. The plastics can do this from the group polypropylene, polyethylene, polyester, polyacrylate, polyamide or polystyrene.

Anschließend wird die innere, dem Behälter zugewandte Lage 3 an ihrer dem Behälter zugewandten Oberflächenseite 3" mit einer heißsiegelbaren Schicht 5 versehen. Diese kann beispielsweise aus einem Heißsiegellack oder einem peelfähigen Kunststofffilm ausgebildet werden. Weiters ist es denkbar, die heißsiegelbare Schicht 5 durch Coextrusionsbeschichtung aufzubringen. Maßgeblich ist es, dass durch Auswahl der heißsiegelbaren Verbindungen, ihrer chemischen Konstitution sowie ihres Vernetzungsgrades beim Heißsiegelvorgang eine Verbundhaftung zwischen der inneren Lage 3 und dem Behälterrand 8 derart erzeugt wird, dass diese größer ist als jene Verbundhaftung, die durch Maßgabe der kaltsiegelnden Schicht 4 zwischen den Lagen 2 und 3 des Deckelelementes erzeugt wird.Subsequently, the inner, the container facing layer 3 at her the container facing surface side 3 "with a heat-sealable Layer 5 provided. This can, for example, from a heat sealing lacquer or a peelable plastic film are formed. Further it is conceivable, the heat-sealable layer 5 by co-extrusion coating applied. Decisive is that by selecting the heat-sealable Compounds, their chemical constitution and their degree of crosslinking in the heat sealing process, a bond between the inner Layer 3 and the container edge 8 is generated such that it is larger is as those composite adhesion, by the proviso of the cold sealing Layer 4 is produced between the layers 2 and 3 of the cover element.

Vorteilhaft ist es weiters, dass die heißsiegelbare Schicht 5 oberflächenrau ausgestaltet ist, da dies das Entstapeln der überlicherweise in Magazinen übereinander gelagerten Deckelelemente wesentlich erleichtert. Besonders vorteilhaft ist die Ausgestaltung der oberflächenrauen heißsiegelbaren Schicht 5 in Form geometrisch angeordneter Abstandshalter 6. Diese Abstandshalter schließen, bedingt durch ihre geometrische Anordnung, in den ebenso regelmäßig angeordneten Zwischenräumen Luft ein, sodass der vorgenannte Entstapelungsvorgang noch zusätzlich erleichtert ist. Der rasche Entstapelungsvorgang ist insbesondere dann von großem Vorteil, wenn, wie im Falle von verderblichen Lebensmitteln, diese beim Abpacken besonders sorgfältig und luftdicht verschlossen sein müssen.It is also advantageous that the heat-sealable layer 5 surface gray is designed as this is the unstacking of the usual greatly facilitated in magazines stacked lid elements. Particularly advantageous is the design of the surface gray heat-sealable layer 5 in the form of geometrically arranged spacers 6. These spacers close, due to their geometric Arrangement, in the equally regularly spaced spaces Air, so that the aforementioned Entstapelungsvorgang even more is relieved. The fast unstacking process is particularly then of great advantage if, as in the case of perishable food, These must be carefully and hermetically closed during packaging have to.

Die beispielsweise so hergestellte innere Lage 3 des Deckelelementes 1 kann nunmehr, wie in Fig. 1 gezeigt, eine in sich geschlossene Oberfläche haben.The inner layer 3 of the cover element 1, for example, thus produced can now, as shown in Fig. 1, a self-contained surface to have.

Gemäß Ausführungsformen nach Fig. 2 und 3 kann die innere Lage 3 jedoch auch Sollbruchstellen 10 oder Perforationen 11 aufweisen.According to embodiments of FIGS. 2 and 3, however, the inner layer 3 also have predetermined breaking points 10 or perforations 11.

Die Sollbruchstellen 10 werden beispielsweise durch Anstanzen erzeugt und dienen dazu, dass beispielsweise beim Erwärmen von Mikrowellengerichten gegebenenfalls entstehende Dämpfe abweichen können, ohne dass es zu einer Verschmutzung des Mikrowellenherdes kommt.The predetermined breaking points 10 are generated for example by punching and serve, for example, when heating microwave dishes possibly resulting vapors may deviate without it Pollution of the microwave oven comes.

Die innere Lage kann weiters mit Perforationen 11 versehen werden, welche beispielsweise die Form einer Ausgießöffnung 12 darstellen. Diese wird beim partiellen Öffnungsvorgang gebildet und ermöglicht bei großen Packungsinhalten auch die teilweise Entnahme von Packungsgut.The inner layer may further be provided with perforations 11, which represent, for example, the shape of a pouring opening 12. These is formed in the partial opening process and allows for large Package contents also the partial removal of packaged goods.

Eine weitere mögliche Ausführungsform des erfindungsgemäßen deckelförmig ausgestanzten Elementes ist gemäß Fig. 4 wiedergegeben. Dabei weist die dem Behälter zugewandte innere Lage 3 die Form eines durchbrochenen Gitters 14 auf. Dieses Gitter 14 besteht aus den Längsfäden 15 und den Querfäden 16, welche aus heißsieglebaren Kunststoffen, beispielsweise aus Polypropylen, Polyethylen, Polyester, Polyacrylat, Polyamid und Polystyrol gebildet werden. Die zwischen den Längs- bzw. Querfäden 15 und 16 ausgebildeten Gitterdurchbrechungen 17 ermöglichen nach partieller Öffnung die dosierte Ausgabe von streufähigem Packungsgut, wie Gewürzen, Salz oder Pfeffer, bei welchen während der Lagerung und auch nach dem Öffnen des Behälters der notwendige Aromaschutz gewährleistet sein soll.Another possible embodiment of the invention cover-shaped punched element is shown in FIG. 4. In this case, the the inner layer facing the container 3 in the form of a perforated Grid 14 on. This grid 14 consists of the longitudinal threads 15 and the Cross threads 16, which made of heat sealable plastics, for example of polypropylene, polyethylene, polyester, polyacrylate, polyamide and Polystyrene are formed. The between the longitudinal and transverse threads 15th and 16 formed grid openings 17 allow for partial Opening the metered output of spreadable packaged goods, such as Spices, salt or pepper, during which during storage and also after opening the container ensures the necessary aroma protection should be.

Nach Herstellen bzw. Vorbereiten der äußeren Lage 2 bzw. der inneren Lage 3 werden diese über ihre einander zugewandten Oberflächenseiten 2' und 3' durch die kaltsiegelnde Schicht 4 in einem Kaltkaschiervorgang miteinander verbunden. Dies erfolgt beispielsweise in einer Kaschierstation bestehend im Wesentlichen aus einem Kaschierwalzenpaar, wobei die Lagen 2 und 3 jeweils an einer Walzenoberfläche derart aneinander herangeführt werden, dass die kaltsiegelnde Schicht 4, welche beispielsweise auf der Lage 2 angebracht ist, der Oberflächenseite 3' der Lage 3, welche über die zweite Kaschierwalze geführt wird, zugewandt ist. Bedingt durch den im Walzenspalt ausgebildeten Anpressdruck erfolgt bei Raumtemperatur über die kaltsiegelnde Schicht 4 eine klebende Verbindung über die Oberflächenseiten 2' und 3' der Lagen 2 und 3. Da der Kaschiervorgang bei Raumtemperatur erfolgt, verbleibt die heißsiegelbare Schicht 5 im desaktivierten Zustand, d.h. es erfolgen noch keine wie immer gearteten Vernetzungsreaktionen, welche eine in diesem Stadium unerwünschte Verbundhaftung bewirken.After making or preparing the outer layer 2 or the inner Layer 3, these are on their mutually facing surface sides 2 ' and 3 'through the cold-sealing layer 4 in a cold-laminating process connected with each other. This takes place, for example, in a laminating station consisting essentially of a laminating roller pair, wherein the layers 2 and 3 in each case on a roll surface in such a way be introduced that the cold-sealing layer 4, which, for example is mounted on the layer 2, the surface side 3 'of the layer 3, which is guided over the second laminating, facing. conditioned by the contact pressure formed in the nip takes place at Room temperature over the cold-sealing layer 4 an adhesive bond over the surface sides 2 'and 3' of the layers 2 and 3. Since the lamination process At room temperature, the heat-sealable layer remains 5 in the deactivated state, i. there are still none as usual type of crosslinking reactions, which is undesirable at this stage Bonding effect.

Die Lagen 2 und 3 sind nunmehr über ihre Oberflächen 2' und 3' durch die kaltsiegelnde Schicht 4 verbunden. Dieser Verbund wird als Rollenware gelagert, aus welcher die Elemente zum Verschließen in der entsprechenden Deckelform ausgestanzt werden können. Dabei kann ebenso an den kleberfreien Stellen die Ausbildung einer Öffnungshilfe, beispielsweise eine Grifflasche 9, 9', vorgesehen werden. Diese üblicherweise in Magazinen gelagerten Deckelelemente 1 können nunmehr für die weitere Verwendung, d.h. für das Verschließen von Behältern 7, eingesetzt werden. Die Behälter 7, welche mit Joghurt, aber auch rieselfähigem Packungsgut, wie Gewürzen, Salz oder Pfeffer gefüllt sein können, werden kontinuierlich mit den erfindungsgemäßen deckelförmig ausgestanzten Elementen 1 in einem Heißsiegelprozess verschlossen. Durch Anwendung von Druck bei erhöhter Temperatur erfolgt die Aktivierung der chemischen Verbindungen in der heißsiegelbaren Schicht 5 derart, dass eine Verbundhaftung in einem Bereich von größer gleich (≥) 5 N/15 mm (gemessen nach DIN EN 28510-1 "Schälprüfung für flexibel/starr geklebte Proben") zwischen dem Deckelelement 1 und dem Behälterrand 8 erzeugt wird. Diese Verbundhaftung bewirkt auch nach partieller Öffnung des Behälters 7, dass dieser zumindest teilweise luftdicht verschlossen ist. Zum Öffnen selbst wird, wie in den Fig. 1 bis 4 gezeigt, die Grifflasche 9, welche sich in der äußeren Lage 2 befindet, angefasst, und in Richtung des Pfeiles F1 gezogen. Durch die erzeugte Anreißkraft wird die Verbundhaftung zwischen den Lagen 2 und 3 überwunden, sodass die äußere Lage 2 ganz oder teilweise von der darunter liegenden Lage 3 abgezogen werden kann. Damit bei diesem Öffnungsvorgang das Deckelelement 1 tatsächlich partiell abgeschält, d.h. gepeelt werden kann, liegt die Verbundhaftung zwischen der äußeren Lage 2 und der inneren Lage 3 in einem Bereich von 0,2 bis 4,5 N/15 mm (gemessen nach DIN EN 28510-1 "Schälprüfung für flexibel/starr geklebte Proben").The layers 2 and 3 are now on their surfaces 2 'and 3' by the cold-sealing layer 4 connected. This composite is called roll goods stored, from which the elements for closing in the corresponding Lid shape can be punched out. It can also on the glue-free points the formation of an opening aid, for example a gripping tab 9, 9 ', are provided. These usually in magazines stored lid elements 1 can now for further use, i.e. for closing containers 7, are used. The Container 7, which with yogurt, but also free-flowing packaged, such as spices, salt or pepper can be filled continuously with the cover-shaped punched-out elements 1 in accordance with the invention sealed a heat sealing process. By applying pressure at elevated temperature, the activation of the chemical compounds takes place in the heat-sealable layer 5 such that a composite adhesion in a range greater than or equal to (≥) 5 N / 15 mm (measured in accordance with DIN EN 28510-1 "Peel test for flexible / rigidly glued samples") between the Cover element 1 and the container edge 8 is generated. This composite adhesion causes even after partial opening of the container 7 that this at least partially hermetically sealed. To open yourself, As shown in FIGS. 1 to 4, the grip tab 9, which in the outer layer 2 is touched, and in the direction of arrow F1 drawn. Due to the generated scribing force, the adhesion between overcome the layers 2 and 3, so that the outer layer 2 in whole or in part can be deducted from the underlying layer 3. With it this opening operation, the cover element 1 actually partially peeled off, i.e. can be peeled, is the bond between the outer layer 2 and inner layer 3 in a range of 0.2 to 4.5 N / 15 mm (measured according to DIN EN 28510-1 "Peel test for flexible / rigid glued samples ").

Um die durchschnittliche Schälkraft, welche eine Kenngröße für die Verbundhaftung einerseits zwischen dem Behälterrand 8 und der inneren Lage 3 sowie anderseits zwischen der äußeren Lage 2 und der inneren Lage 3 ist, messen zu können, werden zur Durchführung der Schälprüfung Proben der Verbundpartner, nämlich Behälter-Material und innere Lage 3 einerseits sowie innere Lage 3 und äußere Lage 2 andererseits, in Form von Teilverbunden hergestellt. Somit besteht erfindungsgemäß ein Teilverbund aus dem Behälter-Material 7, der heißsiegelbaren Schicht 5 und der inneren Lage 3 und der zweite Teilverbund aus der inneren Lage 3, der kaltsiegelbaren Schicht 4 und der äußeren Lage 2. Aus diesen Teilverbunden werden für die Schälprüfung in Laufrichtung 15 mm breite und ca. 300 mm lange Streifen geschnitten. Anschließend werden die Verbundpartner an den Enden der Proben von Hand voneinander getrennt, damit die freien Enden in die Klemmeinreichtung des Zugprüfgerätes, beispelsweise eines der Fa. Zwick, eingespannt werden können. Bei einer Abzugsgeschwindigkeit von 100 mm/min, einer Einspannlänge von max. 50 mm und einem Abzugswinkel von 90° erfolgt die weitere Prüfung. Das Meßergebnis bzw. der Verlauf der Schälfestigkeit (Verbundhaftung) wird entweder am Zugprüfgerät abgelesen oder mit dem Diagrammschreiber aufgezeichnet. Aus den Ergebnissen jeder Versuchsserie werden die Mittelwerte in N/15mm errechnet.To the average peeling force, which is a parameter for the Composite adhesion on the one hand between the container edge 8 and the inner Layer 3 and on the other hand between the outer layer 2 and the inner layer 3 is to be able to measure, are to carry out the peel test samples the composite partner, namely container material and inner layer 3 on the one hand and inner layer 3 and outer layer 2 on the other hand, in the form of Partially made. Thus, according to the invention there is a partial composite from the container material 7, the heat-sealable layer 5 and the inner layer 3 and the second partial composite from the inner layer 3, the cold-sealable layer 4 and the outer layer 2. From these Teilverbunden be used for the peel test in the direction of 15 mm wide and cut about 300 mm long strips. Subsequently, the partners become partners hand-separated at the ends of the samples so that the free ends in the Klemmeinreichtung the Zugprüfgerätes, beispelsweise one of the company Zwick, can be clamped. At a take-off speed of 100 mm / min, a clamping length of max. 50 mm and a deduction angle of 90 °, the further examination. The measurement result or the course of the peel strength (bond adhesion) is either on Tensile tester read or recorded with the chart recorder. From the results of each series of experiments, the mean values in N / 15mm calculated.

Wie in Fig. 2c dargestellt, wird es erforderlich sein, die gesamte Lage 2 von der Lage 3 abzuziehen, da eine derartige Ausführungsform des erfindungsgmäßen Deckelelementes 1 zum Verschließen von Mikrowellenbehältern geeignet ist. Dabei soll die beispielsweise aus Aluminium bestehende Lage 2 vor dem Gebrauch in der Mikrowelle abgezogen werden, damit Aluminium den Durchgang der Mikrowellen nicht stört bzw. verhindert. Durch die Sollbruchstellen 10 können die beim Erwärmen entstehende Dämpfe entweichen, sodass ein Verschmutzen des Mikrowellenherdes unterbleibt.As shown in Figure 2c, it will be necessary to have the entire layer 2 deduct from the situation 3, since such an embodiment of the erfindungsgmäßen cover element 1 for closing microwave containers suitable is. It should be made of aluminum, for example Layer 2 can be stripped in the microwave before use, so that Aluminum does not disturb or prevent the passage of the microwaves. Due to the predetermined breaking points 10, the resulting during heating Vapors escape, so that contamination of the microwave oven is avoided.

Beim partiellen Öffnen eines Behälters 7, wie dies gemäß Fig. 3c gezeigt wird, wird jedoch durch Anwendung der Anreißkraft F1 gleichzeitig eine Ausgießöffnung 12 gebildet. Dies erfolgt durch Einreißen entlang der Perforationen 11, sodass an der von der Lage 3 abgezogenen äußeren Lage 2 die entsprechende Form 13 der Ausgießöffnung 12 haften bleibt. Bei dieser Ausführungsform ist es ausreichend, dass die äußere Lage 2 lediglich partiell zumindest im Bereich der Ausgießöffnung 12 abgezogen wird, um für den Konsumenten die teilweise Entnahme von Packungsgut über diese Ausgießöffnung 12 zu ermöglichen. Für die weitere Lagerung ist es möglich, durch Andrücken der äußeren Lage 2 an die Lage 3 eine Art Wiederverschließbarkeit der Packung zu gewährleisten. Dies erfolgt durch entsprechende Auswahl der kaltsiegelnden Schicht 4, welche beispielsweise in Form eines drucksensitiven Klebers, vorliegen kann.When partially opening a container 7, as shown in FIG. 3c is, however, by applying the scribe force F1 simultaneously Pouring 12 formed. This is done by tearing along the Perforations 11, so that at the deducted from the layer 3 outer layer 2, the corresponding mold 13 of the pouring 12 sticks. at In this embodiment, it is sufficient that the outer layer 2 only partially deducted at least in the region of the pouring opening 12 In order for the consumer to be partially removed from packaging to allow this pouring opening 12. It is for further storage possible, by pressing the outer layer 2 to the layer 3 a kind Reclosability of the package to ensure. This is done by corresponding selection of the cold-sealing layer 4, which for example in the form of a pressure-sensitive adhesive may be present.

Auch bei der Anwendungsform, wie sie gemäß Fig. 4 b gezeigt wird, wird durch Anreißen an der Grifflasche 9 in Richtung des Pfeiles F1 zumindest teilweise die gitterförmige Struktur 14 frei gelegt. Durch Maßgabe der Gitterdurchbrechungen 17 kann das rieselfähige Packgut, beispielsweise Gewürze, Salz oder Pfeffer, entnommen werden. Auch bei dieser Packungsform wird es ausreichend sein, dass die äußere Lage 2 lediglich partiell von der darunter liegenden Lage 3 abgezogen wird.Also in the application form, as shown in FIG. 4 b, is by tearing on the grip tab 9 in the direction of the arrow F1 at least partially exposed the lattice-shaped structure 14. By the stipulation of Gitterdurchbrechungen 17, the pourable packaged goods, for example Spices, salt or pepper, are taken. Also with this package form it will be sufficient that the outer layer 2 only partially is subtracted from the underlying layer 3.

Zusammenfassend lässt sich sagen, dass sich durch die unterschiedliche Einstellung der Verbundhaftung zwischen den Lagen 2 und 3 des erfindungsgemäßen deckelförmig ausgestanzten Elementes einerseits und jener Verbundhaftung zwischen dem Behälterrand 8 und der Deckelelementoberfläche 3, ein Öffnungsmechanismus gezielt derart einleiten läßt, dass die Lagen 2, 3 des Deckelelementes 1 ganz oder teilwiese voneinander abgezogen werden können. Wird die äußere Lage 2 zur Gänze von der Lage 3 abgezogen, so werden beispielsweise die Sollbruchstellen 10 an der inneren Lage 3 freigelegt. Wird in dem Behälter 7 nunmehr Packungsgut, welches sich zum Erwärmen in Mikrowellenöfen eignet, gelagert, so können durch die freigelegten Sollbruchstellen 10 die beim Erwärmen üblichen Dämpfe entweichen, sodass ein unerwünschtes Verschmutzen des Mikrowellenofen unterbleibt.In summary, it can be said that the different Setting the composite adhesion between the layers 2 and 3 of the invention cover-shaped punched element on the one hand and that Bonding between the container edge 8 and the lid member surface 3, an opening mechanism can specifically initiate such that the layers 2, 3 of the cover element 1 completely or partially meadow from each other can be deducted. Will the outer layer 2 entirely on the location 3 deducted, for example, the predetermined breaking points 10 at the inner layer 3 exposed. Is now in the container 7 packaged, which is suitable for heating in microwave ovens stored so can by the exposed predetermined breaking points 10, the usual during heating Vapors escape, causing unwanted fouling of the microwave oven omitted.
