An independent claim is also included for a film material used for producing the packaging. Preferred Features: Recesses extend from edge to edge of the packaging, preferably only in defined regions of the packaging. A protective seal is provided around the recesses. Intermediate layers, preferably barrier layers, absorber layers or browning layers, are arranged between the inner and outer layers.

Description

  • Die Erfindung betrifft eine Verpackung für Lebensmittel, Fertiggerichte, Non Food - Produkte, wie Cold-Hot-Packs, verpackte Erfrischungstücher und dergleichen, die zur Verwendung in der Mikrowelle, im Ofen oder im Wasserbad geeignet ist. The invention relates to a packaging for food products, ready meals, non - food products such as cold-hot packs, packaged refreshing towels and the like, which is suitable for use in the microwave, in the oven or in a double boiler.
  • Lebensmittel oder Fertiggerichte, die in einer Verpackung erwärmt werden, insbesondere in einem Mikrowellenofen oder einem Ofen oder einem Wasserbad, sind bekannt. Food or ready-made meals which are warmed in a packaging, in particular in a microwave oven or an oven or a water bath are known.
    Unter Verpackungen werden starre, halbstarre oder flexible Verpackungen verstanden. Subpackages rigid, semi-rigid or flexible packaging are understood.
    Derartige Verpackungen neigen aufgrund der mit der Erwärmung einhergehenden Ausdehnung des Inhalts und der Ausdehnung von Luft und Gasen zum Aufplatzen oder Bersten. Such packages tend due to the accompanying with the heating expansion of the contents and the expansion of air and gases to burst or burst.
    In beschränktem Maße kann diese Gefahr durch Verwendung von Verpackungen, die deutlich größer dimensioniert sind als das Volumen des Füllguts, vermindert werden. To a limited degree this risk, by using packaging that is dimensioned substantially greater than the volume of the filling material can be reduced.
    Ferner wird das im Füllgut vorhandene Wasser bei der Erwärmung in Dampf umgewandelt. Further, the filling material present in the water is converted upon heating into steam. Dieser Dampf kann durch die üblichen versiegelten Verpackungen nicht oder nur schwer entweichen, es ist daher kein knuspriges Erwärmen von Fertiggerichten möglich. This steam can not or not easily escape through the usual sealed packages, it is therefore no crunchy heating of ready meals possible.
  • Aus der From the EP 661 219 B1 EP 661 219 B1 ist eine Verpackung bekannt, die einen mehrlagigen Aufbau aufweist. discloses a package having a multilayer structure. Dabei sind die Außenlage und die Innenlage wärmefrei miteinander verschmelzbar. The outer layer and the inner layer are heat-fused to each other freely. Ferner ist ein Verbindungsteil vorgesehen, durch den die Außenschicht mit einer Innenschicht durch ein Verbindungsmittel miteinander verbunden ist und ein Bereich, in dem die Außenschicht nicht mit der Innenschicht verbunden ist, sodass ein kommunizierender Durchgang gebildet wird, der eine Ausgangsöffnung zum Außenraum aufweist. Further, a connection part is provided, through which the outer layer having an inner layer by a connecting means is connected to each other and a region in which the outer layer is not bonded to the inner layer so that a communicating passage is formed, which has an output opening to the exterior.
    An der Innenseite sind Mittel vorgesehen, die den Innenraum mit dem kommunizierenden Durchgang verbinden. On the inner side means are provided which connect the interior space with the communicating passage. Die Ausgangsöffnung ist mit einer Klebeschicht versehen, die bei Überschreiten eines bestimmten Drucks im Innenraum der Verpackung aufbricht. The exit orifice is provided with an adhesive layer, which breaks when exceeding a certain pressure in the interior of the package.
    Dadurch wird ein bestimmter Überdruck in der Verpackung bei der Erwärmung in der Mikrowelle gewährleistet, ferner wird ein kontrolliertes Entweichen des Überdrucks ab einem bestimmten Wert gewährleistet. Thereby, a certain excess pressure in the package upon heating in a microwave oven is ensured, further comprising a controlled escape of overpressure from a certain value is ensured.
  • Aus der From the WO 03/051745 A WO 03/051745 A ist eine Verpackung eines ungeöffnet erwärmbaren, insbesondere mikrowellenerhitzbaren Gutes bekannt, die mindestens einen Versiegelungsbereich aufweist, der bei Überschreitung eines bestimmten Innendrucks lokal durchlässig wird, wobei dieser Versiegelungsbereich mindestens einen Solldurchlassabschnitt aufweist, der eine Drossel für den Verpackungsinhalt bildet, und der in Form eines kanalartigen Durchlasses ausgebildet ist, und eine dem Verpackungsinnenraum zugewandte Spitze umfasst, die vorzugsweise umsiegelt ist. is a packaging unopened heatable a particular microwavable material is known which comprises at least one sealing area that is locally permeable if it exceeds a certain internal pressure, said sealing portion having at least one target passage section, forming a choke for the package contents, and a channel-like in shape passage is formed, and a surface facing the package interior tip comprises, preferably umsiegelt.
  • Nachteil dieser Ventilkonstruktion ist, dass das Ventil nicht nur bei durch Erwärmung induziertem Überdruck von innen, sondern auch bei mechanischem Druck leicht öffnet. The disadvantage of this valve design is that the valve easily opens not only induced by heating excess pressure from the inside, but also in mechanical pressure. Ferner ist der Durchgangskanal nicht exakt dimensionierbar. Further, the passageway is not precisely dimensioned. Außerdem besteht die Möglichkeit, dass während der Herstellung, Autoklavierung, Sterilisation, Lagerung oder Erwärmung Füllgut aus der Verpackung ins Ventil migriert, das Füllgut drückt das Ventil dann vorzeitig auf und kann in den umgebenden Raum des Mikrowellenofens austreten. It is also possible that migrated during manufacture, autoclaving, sterilization, storage or heating contents from the packaging into the valve, the filling then depresses the valve to prematurely and may escape into the surrounding space of the microwave oven. Es besteht aber auch die Möglichkeit, dass das Ventil durch das eingedrungene Füllgut verstopft wird und der Dampf nicht im notwendigen Ausmaß entweichen kann. There is also the possibility that the valve is blocked by the penetrated the filling material and the steam can not escape to the extent necessary.
  • Aus der From the WO 04/13015 A WO 04/13015 A ist eine Verpackung bekannt, die einen Absorber für die beim Erwärmen entweichende Feuchtigkeit aufweist, wodurch eine knusprigere Zubereitung möglich ist. discloses a package comprising an absorber for the escaping moisture upon heating, whereby a crisper preparation is possible. Ohne Ventil, durch das überschüssiger Dampf entweichen kann, wird der Absorber aber zu schnell aufgebraucht. can escape without valve through which excess steam, the absorber but is used up too quickly.
  • Aufgabe der Erfindung war es, eine für die Erwärmung in der Mikrowelle, im Ofen oder im Wasserbad geeignete Verpackung bereitzustellen, in der einerseits der Aufbau eines definierten Überdrucks und ein kontrolliertes Entweichen des Dampfes möglich ist, andererseits auch je nach eine knusprige bräunende Zubereitung oder eine Dampfgarung des Füllgutes gewährleistet ist. The object of the invention to provide a provide suitable packaging for heating in a microwave oven, in an oven or in a water bath, in the one hand, the structure of a defined positive pressure and a controlled escape of the vapor is possible, on the other hand, depending on a crispy tanning preparation or a steam cooking of the filling is guaranteed.
  • Gegenstand der Erfindung ist daher eine zur Erwärmung im Mikrowellenofen, im Ofen oder im Wasserbad geeignete Verpackung, bestehend aus einem mehrlagigen Folienmaterial, die mindestens einen Bereich aufweist, der bei Überschreiten eines durch die Mikrowellenerhitzung erzeugten Innendrucks durchlässig wird, wobei die Folie eine äußere Schicht 1 und eine innere Schicht 2, aufweist, wobei die innere Schicht eine sich durch die gesamte Dicke der inneren Schicht erstreckende Ausnehmung 3 aufweist, und die innere Schicht mit der äußeren Schicht mittels eines Klebemittels, wie Kaschierkleber oder Heißsiegelkleber mit einander verbunden ist, dadurch gekennzeichnet, dass die äußere Schicht zumindest in dem durch die Ausnehmung der inneren Schicht definierten Bereich und/oder im die Ausnehmung umgebenden Bereich eine energieabsorbierende Beschichtung oder Bedruckung aufweist, wodurch durch die Siegelschicht erwärmt wird und die Siegelhaftung vermindert bzw. gelöst wird. The invention is therefore suitable for heating in a microwave oven, in an oven or in a water bath packaging, consisting of a multilayer film material having at least one area which is permeable when exceeding an internal pressure generated by microwave heating, said film having an outer layer 1 and an inner layer 2, wherein the inner layer has a through the entire thickness of the inner layer extending recess 3, and the inner layer with the outer layer by an adhesive, such as laminating adhesive or heat-sealing adhesives is connected to each other, characterized in that that the outer layer surrounding at least in the space defined by the recess of the inner layer portion and / or in the recess portion includes an energy-absorbing coating or printing, which is heated by the sealing layer and will reduce the seal adhesion or dissolved.
  • Dadurch kann das Ventil nur bei Erwärmung der Verpackung in der Mikrowelle geöffnet werden. The valve can be opened only with heating of the packaging in the microwave.
  • Die äußere Schicht 1 besteht vorzugsweise aus einer Folie aus Kunststoff, beispielsweise Polyester, wie orientiertes PET amorphes PET, Polyolefine wie Polypropylen, Cast-PP, geblasenen, gereckte, biaxial gereckte PP-Folien, oder Polyethylen, Polystyrol, Polycarbonat, Zellglas, Polyamid, Polyvinylchlorid oder deren Copolymere. The outer layer 1 is preferably made of a sheet of plastic, for example polyester, such as oriented PET, amorphous PET, polyolefins such as polypropylene, cast PP, blown, stretched, biaxially oriented PP films, or polyethylene, polystyrene, polycarbonate, cellophane, polyamide, polyvinyl chloride or copolymers thereof. Es können aber coextrudierte oder laminierte Kunststoffverbundfolien oder Verbunde mit Papier verwendet werden. However, it is co-extruded or laminated plastic composite films or composites are used with paper. Ferner ist es möglich beschichtete Folien, biologisch abbaubare Folien, Aluminiumfolien und dergleichen zu verwenden. Further, it is possible to coated films to use biodegradable films, aluminum foils and the like. Die Dicke der äußeren Schicht beträgt vorzugsweise 8 - 200 µm. The outer layer thickness is preferably 8-200 microns.
  • Die innere Schicht 2 besteht vorzugsweise aus einem siegetfähigen Medium, beispielsweise aus Kunststofffolien aus Polyolefinen, wie Polyethylen, Polypropylen, aus EVOH, EVA, und/oder dessen Copolymeren oder Terpolymeren, Polystyrol, Polycarbonat, Zellglas, Polyamid, Polyvinylchlorid. The inner layer 2 preferably consists of a siegetfähigen medium, for example, plastic films made of polyolefins such as polyethylene, polypropylene, EVOH, EVA, and / or its copolymers or terpolymers, polystyrene, polycarbonate, cellophane, polyamide, polyvinyl chloride. Die innere Schicht kann aber auch durch eine Extrusionsbeschichtung oder Lackierung der äußeren Folie mit einem der genannten Kunststoffe gebildet werden. However, the inner layer may also be formed by an extrusion coating or painting of the outer film to one of said plastics.
    Die Dicke der inneren Schicht beträgt vorzugsweise 0,5 - 100 µm. The thickness of the inner layer is preferably 0.5 to 100 microns.
  • Die Ausnehmung kann sich von Kante zu Kante der Verpackung erstrecken oder nur über einen bestimmten Bereich. The recess may extend from edge to edge of the packaging, or only over a certain range. In diesem Fall können auch mehrere derartiger Ausnehmungen über die Fläche verteilt vorhanden sein. In this case, a plurality of such recesses may be present distributed over the surface.
    Die Ausnehmungen können dabei beispielsweise in Form eines Schlitzes, Kreises, Rechtecks, Trapezes, Dreiecks etc. ausgebildet sein. The recesses may be designed etc., for example in the form of a slot, circle, rectangle, trapezium, triangle.
    Im Bereich des Ventils ist eine Schutzsiegelung zum Schutz vor unbeabsichtigtem und/oder vorzeitigem Öffnen vorgesehen. In the area of ​​the valve, a protective seal for the protection is provided against accidental and / or premature opening. Durch die Haftung der Schutzsiegelung wird der Öffnungsdruck des Ventils bei Erwärmung eingestellt. By the adhesion of the protective sealing the opening pressure of the valve during heating is set. Je nach Erfordernis kann dabei je nach Haftkraft der Schutzsiegelung der erforderliche Öffnungsdruck in einem weiten Bereich variiert werden. Depending on requirements, while the required opening pressure can be varied over a wide range depending on the adhesive force of the protective seal. Dabei wird die Haftkraft in erster Linie durch die Form der Schutzsiegelung und das Haftmittel bestimmt. The adhesive force is determined primarily by the shape of the protective seal and the adhesive.
  • Gegebenenfalls kann in der Schutzsiegelung eine Schwachstelle eingebaut werden, um ein verlässliches Öffnen des Ventils sicherzustellen. Optionally, in the protective sealing a vulnerability can be installed to ensure a reliable opening of the valve. Dies kann beispielsweise durch eine definierte begrenzte Unterbrechung der Siegelschicht oder durch Einbringen von definierten Vorsiegelbereichen oder -punkten erfolgen. This can be done for example by a defined limited interruption of the sealing layer or by introducing defined temporary-or points.
    Die das Ventil umgebende Schutzsiegelung kann dabei unterschiedliche Formen aufweisen. The valve surrounding protective seal can have different shapes. Sie kann in Form des Ventils ausgeführt sein, oder auch unabhängig von der Form des Ventils beispielsweise in Form einer Spitze, eines Trapezes, in Form von Linienstrukturen, in Form eines Rasters, in Form eines Doppelspitzes und dergleichen. It can be in the form of the valve, or even irrespective of the shape of the valve, for example in the form of a tip, a trapezoid, like in the form of linear structures, in the form of a grid, in the form of a double lace and.
  • Zwischen der äußeren und der inneren Schicht können gegebenenfalls Zwischenschichten situiert sein. Between the outer and the inner layer between layers may be situated, if necessary.
