Abstract
Description
Die Erfindung betrifft einen flachgelegten Folienbeutel zum Erhitzen von Lebensmitteln.The invention relates to a flattened foil bag for heating food.
Kunststofffolienbeutel bilden eine kostengünstige, saubere und vielseitige Möglichkeit, Lebensmittel während des Garprozesses abzuschließen. Ein Beispiel hierfür sind sogenannte Bratschläuche, in denen ein Lebensmittel, vorzugsweise Fleischstücke, während eines Garprozesses abgeschlossen werden, um ein Austrocknen zu verhindern. Um den Folienbeutel zu verschließen, existieren verschiedene Ansätze. Beispielsweise kann der Beutel mit Wiederverschlüssen, wie z. B. verrastbaren Profilstreifen oder Schieberverschlüssen ausgestattet sein. Wiederverschlüsse sind allerdings aufwendig und teuer. In funktionsmäßiger Hinsicht haben sie den Nachteil, dass sie steif sind und dadurch der Folienbeutel vor seinem Gebrauch nicht platzsparend gefaltet werden kann. Ferner besteht die Möglichkeit, Folienbeutel durch Verwendung einer separaten Verschlussklemme zu verschließen. Die Benutzung von Verschlussklemmen ist erklärungsbedürftig. Ferner besteht die Gefahr, dass Verschlussklemmen als Kleinteile verloren gehen bzw. vom Benutzer nicht verwendet oder beachtet werden.Plastic film bags provide a cost effective, clean and versatile way to finish food during the cooking process. An example of this are so-called Bratschläuche in which a food, preferably pieces of meat, are completed during a cooking process to prevent drying out. To close the foil bag, there are different approaches. For example, the bag with reclosings, such. B. latchable profile strips or slide closures. Reclosures are however complicated and expensive. In terms of function, they have the disadvantage that they are stiff and thus the film bag can not be folded to save space before use. It is also possible to close foil pouches by using a separate closure clamp. The use of locking clamps is in need of explanation. Furthermore, there is a risk that locking clips are lost as small parts or are not used or observed by the user.
Beim Erhitzen eines Lebensmittels wird regelmäßig Wasserdampf freigesetzt. Ferner dehnt sich die im verschlossenen Folienbeutel eingeschlossene Luft bei Erwärmung aus. In der Folge entsteht ein Überdruck innerhalb des Folienbeutels. Wird dieser zu groß, ohne dass ein Druckausgleich stattfindet, kann der Folienbeutel platzen und seinen Inhalt unkontrolliert in den Innenraum der Erwärmungsvorrichtung entleeren. Wird der Folienbeutel jedoch nicht dicht ausgeführt, so dass erwärmte Luft und Wasserdampf ungehindert entweichen können, verliert er seine Schutzwirkung und das Lebensmittel kann während des Erwärmprozesses austrocknen. Die beschriebenen Probleme treten insbesondere bei einer Mikrowellenerhitzung des Lebensmittels auf.Heating a food regularly releases water vapor. Furthermore, the trapped air in the sealed foil bag expands when heated. As a result, an overpressure arises within the film bag. If this becomes too large without pressure equalization taking place, the film bag can burst and empty its contents uncontrollably into the interior of the heating device. However, if the film bag is not tightly designed so that heated air and water vapor can escape unhindered, it loses its protective effect and the food can during dry out of the heating process. The described problems occur in particular in the case of microwave heating of the food.
Vor diesem Hintergrund liegt der Erfindung die Aufgabe zugrunde, einen Folienbeutel zur Erhitzung von Lebensmitteln anzugeben, welcher kostengünstig produzierbar ist, besonders leicht auf kleine Abmessungen zusammenfaltbar ist und während des Erwärmungsprozesses eine stabile, kontrollierte Atmosphäre für das zu erwärmende Lebensmittel bereitstellt.Against this background, the invention has for its object to provide a film bag for heating food, which is inexpensive to produce, is particularly easy to fold to small dimensions and provides a stable, controlled atmosphere for the food to be heated during the heating process.
Gegenstand der Erfindung und Lösung dieser Aufgabe ist ein Folienbeutel nach Anspruch 1. Eine erfindungsgemäße Verwendung des Folienbeutels ist Gegenstand des Anspruches 6.The invention and solution to this problem is a film bag according to
Zum grundsätzlichen Aufbau des zum Erhitzen von Lebensmitteln bestimmten Folienbeutels gehört eine Frontwand, eine Rückwand und eine Füllöffnung an einem oberen Beutelrand. Am oberen Beutelrand sind zwei Verlängerungen vorgesehen, durch deren Verknoten der Folienbeutel luftdicht verschlossen werden kann. Der Folienbeutel weist eine Entlüftungseinrichtung zum Ausleiten von Luft und/oder Dampf auf, die bei einem beutelinnenseitigen Überdruck selbsttätig öffnet. Der Folienbeutel kann ohne zusätzliche Hilfsmittel durch Knoten sicher und luftdicht verschlossen werden. Hierdurch wird die vom Lebensmittel während des Erwärmens gebildete Dampfatmosphäre am Lebensmittel gehalten und kann ein Austrocknen verhindert werden. Die Entlüftungseinrichtung lässt Teile dieser Garatmosphäre bei einem beutelinnenseitigen Überdruck kontrolliert entweichen. Durch entsprechende Ausgestaltung der Entlüftungseinrichtung kann der Überdruck in einem vorherbestimmten Bereich begrenzt und dadurch ein unkontrolliertes Aufplatzen des Folienbeutels verhindert werden.The basic structure of the intended for heating food foil bag includes a front wall, a rear wall and a filling opening at an upper edge of the bag. At the upper edge of the bag two extensions are provided, by knotting the foil bag can be hermetically sealed. The film bag has a venting device for discharging air and / or steam, which automatically opens when the inside of the bag is pressurized. The film bag can be safely and hermetically sealed by knots without additional aids. As a result, the vapor atmosphere formed by the food during heating is held on the food and drying can be prevented. The venting device allows parts of this cooking atmosphere to escape in a controlled manner when the inside of the bag is pressurized. By appropriate design of the venting the overpressure can be limited in a predetermined range and thereby uncontrolled bursting of the film bag can be prevented.
Vorzugsweise weisen die Frontwand und die Rückwand einen den oberen Beutelrand begrenzenden bogenförmigen Ausschnitt auf. Die verbleibenden Folienabschnitte bilden dann die erfindungsgemäßen Verlängerungen des Folienbeutels.The front wall and the rear wall preferably have an arcuate cutout delimiting the upper edge of the bag. The remaining film sections then form the extensions of the film bag according to the invention.
Die Entlüftungseinrichtung besteht vorzugsweise aus einem an der Frontwand oder der Rückwand angeordneten Etikettenventil. Das Etikettenventil ist flächig ausgebildet und umfasst einen auf dem Folienbeutel befestigbaren Folienabschnitt, der eine Ventileinrichtung aufweist oder als Ventilelement auf den Folienbeutel aufgeklebt ist und eine Entlüftungsöffnung des Folienbeutels abdeckt. Etikettenventile sind aus dem Stand der Technik hinreichend bekannt. Die benötigte Fläche eines Etikettenventils ist im Vergleich zur Beuteloberfläche gering, so dass die Faltbarkeit des Folienbeutels nicht beeinträchtigt wird.The venting device preferably consists of a arranged on the front wall or the rear wall label valve. The label valve has a planar design and comprises a film section which can be fastened on the film bag and which has a valve device or is glued as a valve element onto the film bag and covers a vent opening of the film bag. Label valves are well known in the art. The required area of a label valve is small compared to the bag surface, so that the foldability of the film bag is not affected.
In einer anderen bevorzugten Ausgestaltung der Erfindung besteht die Frontwand und/oder die Rückwand aus einer zumindest zweischichtigen Verbundfolie. Dabei ist die Entlüftungseinrichtung durch eine in die Verbundfolie eingebrachte Perforation oder Schwächungslinie gebildet, welche die Verbundfolie nicht in der gesamten Dicke durchtrennt und erst bei einem beutelinnenseitigen Überdruck aufreißt und dadurch durchgängig wird. Bei dieser Form der Entlüftung sind Optik und Faltbarkeit des Folienbeutels unverändert.In another preferred embodiment of the invention, the front wall and / or the rear wall consists of an at least two-layer composite film. In this case, the venting device is formed by an introduced into the composite film perforation or weakening line, which does not cut through the composite film in the entire thickness and tears only at an inner bag pressure and thus is consistent. In this form of ventilation optics and foldability of the foil bag are unchanged.
In einer weiteren Ausgestaltungsalternative sind die Frontwand und die Rückwand durch randseitige Siegelnähte miteinander verbunden. Dabei kann zumindest eine der Siegelnähte einen Abschnitt mit einer geringeren Siegelnahtfestigkeit aufweisen, der bei einem beutelinnenseitigen Überdruck als Entlüftungseinrichtung wirksam ist. Die Siegelnahtfestigkeit ist ein Parameter, den der Fachmann besonders einfach kontrollieren und variieren kann. Vorzugsweise ist die Siegelnaht nicht über ihre gesamte Länge geschwächt, sondern weist eine oder mehrere lokale Schwächungen auf, deren Länge die Breite der Siegelnaht nicht übersteigt. Hierdurch ergibt sich eine besonders leichte Umsetzung für die Fertigung. Ein Folienbeutel mit einer solchen Entlüftungseinrichtung ist ebenfalls nicht auf den ersten Blick als solcher zu erkennen.In a further embodiment alternative, the front wall and the rear wall are connected to one another by edge sealing seams. In this case, at least one of the sealing seams may have a section with a lower sealing seam strength, which is effective as a venting device when the inside of the bag is pressurized. The seal seam strength is a parameter which the skilled person can control and vary particularly easily. Preferably, the sealing seam is not weakened over its entire length, but has one or more local weakenings whose length does not exceed the width of the sealed seam. This results in a particularly easy implementation for the production. A foil bag with such a venting device is also not recognizable at first glance as such.
Vorzugsweise weisen die Frontwand und die Rückwand jeweils eine Foliendicke zwischen 10 µm und 30 µm auf. In diesem Dickenbereich lassen sich Kunststofffolien fertigen, die nur eine geringe Permeation von Luft und Wasserdampf zulassen, jedoch trotzdem leicht und auf kleinerem Raum zusammenfaltbar bleiben.Preferably, the front wall and the rear wall each have a film thickness between 10 microns and 30 microns. In this thickness range can produce plastic films that allow only a small permeation of air and water vapor, but still fold easily and collapsible in a smaller space.
Der Folienbeutel ist bevorzugt aus einer Folie aus Polypropylen, Polyamid, Polyethylenerepthalat oder Cellulose gefertigte oder besteht aus einer mehrschichtigen Folie, die mindestens eine Schicht aus den vorgenannten Polymeren aufweist. Die genannten Materialien haben sich für Anwendungen von Lebensmitteln, insbesondere bei Temperaturen oberhalb von 200 °C, bewährt. Zweckmäßigerweise weist das Folienmaterial einen Schmelzpunkt oberhalb von 200 °C auf, damit die Stabilität und Integrität des Folienbeutels bei sachgemäßer Anwendung nicht gefährdet und eine Kontamination des Lebensmittels mit gesundheitsgefährdenden Stoffen verhindert wirdThe film bag is preferably made of a film made of polypropylene, polyamide, polyethylene repthalate or cellulose or consists of a multilayer film which has at least one layer of the aforementioned polymers. The materials mentioned have proven useful for food applications, in particular at temperatures above 200 ° C. Appropriately, the film material has a melting point above 200 ° C, so that the stability and integrity of the film bag when used properly does not endanger and contamination of the food with hazardous substances is prevented
Gegenstand der Erfindung ist auch die Verwendung eines Folienbeutels nach einer der vorstehenden Ausführungen zum Dampfgaren von Lebensmitteln in einem Mikrowellengerät. Dabei wird das Lebensmittel in den Folienbeutel eingebracht und dieser durch Verknoten der an dem oberen Beutelrand angeordneten Verlängerungen luftdicht verschlossen. Durch Mikrowellenerhitzen des Lebensmittels innerhalb des verschlossenen Folienbeutels wird eine Dampfatmosphäre erzeugt, deren Druck durch die Entlüftungseinrichtung des Folienbeutels bestimmt ist. Optional kann auch zusammen mit dem Lebensmittel eine Flüssigkeitsmenge in den Folienbeutel eingefüllt werden, welche ebenfalls durch die Wärmeeinwirkung zusätzlich verdampft. Das Lebensmittel kann in dem Folienbeutel nach dem erfindungsgemäßen Verfahren in einem Mikrowellengerät gegart werden, ohne dass zusätzliches Kochgeschirr benötigt wird.The invention also provides the use of a foil bag according to one of the preceding embodiments for the steam cooking of foods in a microwave oven. In this case, the food is introduced into the foil bag and this is hermetically sealed by knotting the arranged on the upper edge of the bag extensions. By microwave heating the food inside the sealed foil bag generates a vapor atmosphere whose pressure is determined by the venting device of the film bag. Optionally, an amount of liquid can also be filled into the foil bag together with the food, which also evaporates in addition by the heat. The food can be cooked in the foil pouch according to the method of the invention in a microwave oven, without the need for additional cookware.
Vorzugsweise wird der Folienbeutel im gefalteten Zustand zusammen mit dem zu garenden Lebensmittel in einer Lebensmittelverpackung bereitgestellt. Der Begriff "Lebensmittel" umfasst insbesondere fertig gemischte Speisen, welche auch vorgegart sein können, und Würzmischungen, die vom Benutzer mit frischen Zutaten vermengt werden müssen.Preferably, the film bag is provided in the folded state together with the food to be cooked in a food package. The term "food" includes, in particular, ready-mixed meals, which may also be pre-cooked, and seasoning mixtures which have to be mixed by the user with fresh ingredients.
