Description

Die Erfindung bezieht sich auf ein Verfahren zur Herstellung von Verpackungen gemäß des Oberbegriffes von Patentanspruch 1 sowie auf eine Verpackung zur Aufbewahrung von Lebensmitteln nach dem Oberbegriff des Patentanspruches 4.The invention relates to a method for the production of packaging according to the preamble of patent claim 1 and to a packaging for storing food according to the preamble of claim 4.

Derartige Verpackungen sind seit Jahrzehnten bekannt und erfolgreich in Gebrauch. Beispielsweise verwendet die Fa. Uncle Ben's Beutel aus Folien, in denen Reis eingefüllt ist. Diese Beutel sind in einer Pappschachtel untergebracht, um den Reis vor Feuchtigkeit zu schützen. Um den in dem Folien-Beutel eingefüllten Reis in einem Warmwasserbad für den menschlichen Genuss zu kochen, sind die einzelnen perforierten Beutel nach dem Aufreißen der Pappschachtel aus dieser zu entnehmen.Such packaging has been known and successfully used for decades. For example, Uncle Ben's uses pouches made of films filled with rice. These bags are stored in a cardboard box to protect the rice from moisture. In order to cook the rice filled in the foil bag in a warm water bath for human consumption, the individual perforated bags are to be taken out of this after the cardboard box has been torn open.

Als nachteilig bei derartigen Verpackungen hat sich herausgestellt, dass die Verpackung zunächst zu öffnen ist, um einen oder mehrere in dieser eingesteckten Beutel entnehmen zu können. Nach dem Erhitzen des Reises in einem Heißwasserbad ist darüber hinaus der Beutel aufzureißen. Dieser ist jedoch nach dem Erhitzungsvorgang umständlich zu handhaben, denn die aufgeheizten Reiskörner strahlen die aufgenommene Hitze ab, so dass der Beutel nicht mit der bloßen Hand angefasst werden kann.A disadvantage of such packaging has been found that the package is first to open to remove one or more inserted in this bag can. In addition, after heating the rice in a hot water bath, the bag should be ruptured. However, this is cumbersome to handle after the heating process, because the heated rice grains radiate the heat absorbed, so that the bag can not be touched with the bare hand.

Außerdem ist diese Verpackungsart nicht geeignet, um sauerstoffempflindliche Lebensmittel unter Begasung zu verpacken, da die Schutzgasatmosphäre aus den Öffnungen in den Kochbeuteln entweichen würde und die äußere Kartonverpackung ihrerseits keine Barriere gegen Gase darstellt.In addition, this type of packaging is not suitable for packaging oxygen-sensitive foods with fumigation, since the protective gas atmosphere from the openings would escape in the cooking bags and the outer cardboard packaging in turn is no barrier to gases.

Des Weiteren ist es bekannt, Lebensmittel, die zur Haltbarmachung zu sterilisieren oder zu pasteurisieren sind und später vom Endverbraucher z.B. im Wasserbad erwärmt werden sollen, in Dosen oder Plastikbeutel einzufüllen, die einer solchen Behandlung standhalten und die eingefüllten Lebensmittel von der Umgebung zuverlässig schützen.Furthermore, it is known to sterilize or pasteurize foods to be preserved and later on by the end user, e.g. To be heated in a water bath, to be filled in cans or plastic bags, which withstand such a treatment and reliably protect the filled food from the environment.

Bei der Handhabung solcher Verpackungen hat sich als nachteilig herausgestellt, dass die Verpackungen zu öffnen sind und die eingefüllten Lebensmittel, beispielsweise Würstchen, einzeln in ein Warmwasserbad zur Erhitzung eingefüllt werden müssen. Nachdem die Würstchen fertig gegart sind, schwimmen diese vereinzelt in dem Warmwasserbad, so dass diese umständlich aus dem Wasserbad entnommen werden müssen. Insbesondere in größeren Garküchen hat sich herausgestellt, dass eine solche Handhabung äußerst unhygienisch ist, denn eine Vielzahl von Personen greifen oftmals mit der bloßen Hand in das Warmwasserbad, um die einzelnen Würstchen herauszuholen. Durch eine solche Kontaktaufnahme werden Bakterien und Viren übertragen die zu gesundheitlichen Schäden oder Beeinträchtigungen beim Verzehr der Würstchen führen können.In the handling of such packaging has been found to be disadvantageous that the packaging must be opened and the filled food, such as sausages, must be individually filled in a hot water bath for heating. After the sausages are cooked, they swim in the warm water bath, so they have to be removed from the water bath. In particular, in larger food stalls has been found that such handling is extremely unhygienic, because a variety of people often grab with his bare hand in the hot water bath to extract the individual sausages. By such contact bacteria and viruses are transmitted which can lead to damage to health or impairment in the consumption of sausages.

Es ist daher Aufgabe der Erfindung, ein Verfahren zur Herstellung von Verpackungen sowie Verpackungen der eingangs genannten Gattung zur Verfügung zu stellen, durch die zum Einen die in die Verpackung eingefüllten Lebensmittel zuverlässig vor Verderb durch Sauerstoff und unhygienischen Kontaminationen während der Lagerzeiten und beim Gebrauch geschützt sind und die zum Anderen gleichzeitig wahlweise eine einfache Entnahme der Lebensmittel für den kalten Verzehr oder die hygienische heiße Zubereitung in der Verpackung mit anschließender einfacher Handhabung der erwärmten Lebensmittel erlauben.It is therefore an object of the invention to provide a method for the production of packaging and packaging of the type mentioned by the one hand, the filled into the packaging food is reliably protected from spoilage by oxygen and unhygienic contaminants during storage and during use and the other at the same time either allow easy removal of the food for cold consumption or hygienic hot preparation in the package with subsequent easy handling of the heated food.

Diese Aufgaben werden erfindungsgemäß durch die Merkmale des kennzeichnenden Teils von Patentanspruch 1 sowie von Patentanspruch 4 gelöst.These objects are achieved by the features of the characterizing part of claim 1 and of claim 4.

Weitere vorteilhafte Weiterbildungen der Erfindung ergeben sich aus den Unteransprüchen.Further advantageous developments of the invention will become apparent from the dependent claims.

Dadurch, dass der innere Beutel an der Innenseite des äußeren Beutels mittels einer Verbindungs-Siegelnaht fest verbunden ist, wird der innere Beutel von dem äußeren Beutel zuverlässig nach außen umschlossen, so dass die eingelagerten Lebensmittel aufgrund des Materialschichtaufbaus des äußeren Beutels vor Kontaminationen mit Bakterien, Viren oder sonstigen Schadstoffen geschützt sind. Eine Begasung des gesamten Beutelinhalts mit Schutzgasatmosphäre ist möglich. Darüber hinaus kann der äußere Beutel von dem inneren Beutel auf einfache und unkomplizierte Weise getrennt werden, indem nämlich die unterhalb der Verbindungs-Siegelnaht angeordnete Perforation in der Wand des äußeren Beutels aufgerissen wird, so dass der innere Beutel und somit die dort eingelagerten Lebensmittel in ein Heißwasserbad oder in eine Mikrowelle zur Erhitzung eingebracht werden können.The fact that the inner bag is firmly connected to the inside of the outer bag by means of a connecting sealing seam, the inner bag is reliably enclosed by the outer bag to the outside, so that the stored food due to the material layer structure of the outer bag from contamination with bacteria, Viruses or other pollutants are protected. A gassing of the entire bag contents with inert gas atmosphere is possible. In addition, the outer bag can be separated from the inner bag in a simple and uncomplicated way, namely by the arranged below the connecting seam perforation in the wall of the outer bag is torn so that the inner bag and thus the food stored there in a Hot water bath or in a microwave for heating can be introduced.

Sollten die Lebensmittel ohne Erhitzung konsumiert werden, kann die obere Perforation des Außenbeutels aufgerissen werden, so dass der unverschlossene innere Beutel frei zugänglich ist oder aber die eine oder andere Siegelnaht, durch die die Seiten des inneren Beutels miteinander verbunden sind, ist peelfähig oder lediglich punktuell ausgebildet, so dass diese aufgerissen werden kann.If the food is consumed without heating, the upper perforation of the outer bag may be torn so that the unlocked inner bag is freely accessible or one or the other sealing seam by which the sides of the inner bag are connected together is peelable or only punctiform trained so that it can be torn open.

Um die Öffnung des inneren Beutel, insbesondere wenn dieser einem Erhitzungsvorgang ausgesetzt gewesen ist, für die Benutzer zu vereinfachen und Verbrennungen zu vermeiden, ist an einer der Außenwände des inneren Beutels eine Lasche angebracht, in die eine Grifföffnung oder Öse eingearbeitet ist. Folglich kann der Benutzer, beispielsweise mittels eines Fingers, in die Öse eingreifen und die Lasche betätigen, die fest mit der Wand des inneren Beutels verbunden ist, um diese von dem inneren Beutel zu trennen.To facilitate the opening of the inner bag, especially when subjected to a heating process, for the user and to prevent burns, a tab is attached to one of the outer walls of the inner bag, in which a handle opening or eyelet is incorporated. Consequently, the user may, for example, by means of a finger, engage in the eyelet and actuate the tab which is fixedly connected to the wall of the inner bag to separate it from the inner bag.

In Figur 1 ist schematisch dargestellt wie eine Verpackung 1 aus einer Folienbahn 3a zur Aufnahme von Lebensmitteln 2 hergestellt wird. Die Folienbahn 3a ist dabei auf einer Rolle 4 aufgewickelt und kann von dieser bei Bedarf abgerollt werden. Die Folienbahn 3a besteht aus mindestens zwei und höchstens sechs unterschiedlichen Materialschichten. Dabei bestehen mindestens die die innere und die äussere Begrenzung des Beutels 11 bildenden Schichten aus Polyolefinen, deren Copolymeren oder einem Blend aus Polyolefinen und deren Copolymeren. Die innerste Polyolefinschicht ist peelfähig ausgerüstet. Die äußerste Polyolefinschicht weist einen um mindestens 5°C höheren Schmelzpunkt auf, als die inneren Schichten.In FIG. 1 schematically shows how a package 1 is made of a film web 3a for receiving food 2. The film web 3a is wound on a roll 4 and can be unwound from this if necessary. The film web 3a consists of at least two and at most six different material layers. In this case, at least the inner and the outer boundary of the bag 11 forming layers of polyolefins, their copolymers or a blend of polyolefins and their copolymers. The innermost polyolefin layer is peelable. The outermost polyolefin layer has a melting point at least 5 ° C higher than the inner layers.

Zur Bildung eines ersten Beutels 11 wird die Folienbahn 3a von der Rolle 4 abgewickelt und zu einer einzelnen Folie 5 geschnitten. Nachfolgend wird die Folie 5 um eine Faltkante 7 gefaltet, so dass eine doppellagige Folie 6 entsteht. Die Folie 6 wird an zwei offenen Stirnseiten mittels einer festen Siegelnaht 8 oder einer peelfähigen Siegelnaht 9 verschweißt.To form a first bag 11, the film web 3a is unwound from the roll 4 and cut into a single film 5. Subsequently, the film 5 is folded around a folding edge 7, so that a double-layered film 6 is formed. The film 6 is welded at two open end faces by means of a solid sealing seam 8 or a peelable sealing seam 9.

Nach dem Versiegeln der beiden senkrecht zueinander verlaufenden Stirnseiten der Folie 6 entsteht der erste Beutel 11.After sealing the two mutually perpendicular end faces of the film 6, the first bag 11 is formed.

Eine der drei Stirnseiten wird nicht verschlossen; diese offene Stirnseite ist mit der Bezugsziffer 13 bezeichnet. Folglich kann durch die offene Stirnseite 13 durch eine Einfüllvorrichtung 10 das Lebensmittel 2 in Form von Würstchen eingefüllt werden. Es ist auch denkbar Gemüse, beispielsweise Spargel, Karottenstücke, Erbsen sowie Saucen, Fleischstücke oder dgl. in den Beutel 11 einzufüllen, die eine aus mehreren Lebensmittel 2 zusammengesetzte Speise ergeben. Zu diesem Zweck können zwei oder mehrere Bereiche innerhalb des Beutels 11 mittels Siegelnähten 8 oder 9 erzeugt werden, in die unterschiedliche Lebensmittel 2 eingefüllt sind, die nach einem Gar- oder Erhitzungsvorgang in dem Beutel 11 oder auf einem Teller für den Konsum zusammengeführt werden können.One of the three faces is not closed; This open end is designated by the reference numeral 13. Consequently, through the open end face 13 through a filling device 10, the food 2 can be filled in the form of sausages. It is also conceivable vegetables, such as asparagus, carrot pieces, peas and sauces, pieces of meat or the like. To fill in the bag 11, which result in a compound of several food 2 food. For this purpose, two or more areas within the bag 11 can be produced by means of sealing seams 8 or 9 into which different foodstuffs 2 are filled, which can be brought together in the bag 11 or on a plate for consumption after a cooking or heating process.

In die beiden gegenüberliegenden Wände des Beutels 11 sind Öffnungen 12 in Form von Kreisen eingearbeitet. Die Querschnittsform der Öffnungen 12 können auch elyptisch, schlitzförmig oder mehreckig sein. Die Durchmesser oder Längenabmessungen der Öffnungen 12 sind an die Größe der eingefüllten Lebensmittel 2 angepasst oder werden bei flüssigen Lebensmitteln 2 nicht eingearbeitet, so dass die Lebensmittel 2 aus den Öffnungen 12 nicht herausrutschen können. Gleichzeitig gewährleisten die Größe, Form und Anzahl der Öffnungen eine gute Durchströmung des Beutels 11 mit dem Schutzgas bei der Begasung bzw. mit Wasser bei der Zubereitung des Lebensmittels 2 im Warmwasserbad.In the two opposite walls of the bag 11 openings 12 are incorporated in the form of circles. The cross-sectional shape of the openings 12 may also be elliptical, slit-shaped or polygonal. The diameter or length dimensions of the openings 12 are adapted to the size of the filled food 2 or are not incorporated in liquid foods 2, so that the food 2 from the openings 12 can not slip out. At the same time ensure the size, shape and number of openings good flow through the bag 11 with the inert gas in the fumigation or with water in the preparation of the food 2 in a hot water bath.

In Figur 2a ist nunmehr gezeigt, dass der erste Beutel 11 mittels einer peelfähigen Siegelnaht 9 an der offenen Stirnseite 13 verschlossen ist und dass dieser in einem zweiten Beutel 14 eingeschoben ist. Die Herstellung des zweiten Beutels 14 erfolgt nachdem in Figur 1 aufgezeigten Verfahrensablauf; allerdings wird zur Erzeugung des Beutels 14 eine Folienbahn 3b verwendet, deren Schichtaufbau nachfolgend erläutert ist.In FIG. 2a is now shown that the first bag 11 is closed by means of a peelable sealing seam 9 at the open end face 13 and that this is inserted in a second bag 14. The production of the second bag 14 takes place after in FIG. 1 demonstrated procedure; However, to produce the bag 14, a film web 3b is used, the layer structure is explained below.

Die zur Herstellung des zweiten Beutels 14 notwendige Folienbahn 3b besteht aus einem mindestens zweilagigen Laminat, wobei mindestens eine der Lagen, vorzugsweise die die Beutelaußenseite bildende, aus einem einreißorientierten, bedruckbarem Material gebildet ist. Die innere Lage des Laminats dient vornehmlich der Versiegelung. Sie besteht aus mindestens einer von Polyolefinen, deren Copolymeren oder einem Blend von Polyolefinen und deren Copolymeren gebildeten Schicht und kann weitere funktionelle Schichten enthalten.The necessary for the production of the second bag 14 film web 3b consists of a least two-ply laminate, wherein at least one of the layers, preferably forming the bag outside, from a tear-oriented, printable Material is formed. The inner layer of the laminate is primarily used for sealing. It consists of at least one layer formed by polyolefins, their copolymers or a blend of polyolefins and their copolymers and may contain further functional layers.

Des Weiteren enthält die Folienbahn 3b mindestens eine gasdichte Barriereschicht, damit im Doppel-Beutel 14 eine Schutzgasatmosphäre aufgebaut und über die vorgesehene Haltbarkeitsdauer des Lebensmittels 2 aufrechterhalten ist.
Diese Barriereschicht ist vorzugsweise als Metallisierung oder glasartige Beschichtung der äußeren Lage des Laminats oder als polymere Barriereschicht in der inneren Lage des Laminats ausgebildet. In diesem Fall wird die Barriereschicht aus der Gruppe der Polyamide, Ethylenvinylalkohole, Polyesterterephtalate oder deren Copolymere gebildet.Furthermore, the film web 3b contains at least one gas-tight barrier layer, so that a protective gas atmosphere is built up in the double bag 14 and maintained over the intended shelf-life of the food 2.
This barrier layer is preferably formed as a metallization or glassy coating of the outer layer of the laminate or as a polymeric barrier layer in the inner layer of the laminate. In this case, the barrier layer is formed from the group of polyamides, ethylene vinyl alcohols, polyester terephthalates or their copolymers.

Die äußere und/oder die innere Lage des äußeren Beutels 14 ist dabei bedruckbar, um das eingefüllte Lebensmittel 2 entsprechend werbewirksam herauszustellen. Des Weiteren können dort die Betriebsanleitung zur Handhabung der Verpackung 1 sowie die Inhaltsstoffe des eingelagerten Lebensmittel 2 erläutert werden.The outer and / or the inner layer of the outer bag 14 is printable to bring out the filled food 2 advertising effective. Furthermore, the operating instructions for handling the packaging 1 and the ingredients of the stored food 2 can be explained there.

Die beiden senkrecht zueinander verlaufenden Siegelnähte 8 sind derart fest miteinander verbunden, dass ein Aufreißen entlang dieser Siegelnaht 8 nicht erfolgen soll.The two mutually perpendicular sealing seams 8 are so firmly connected to each other that a rupture along this seal seam 8 should not take place.

Nachdem der innere Beutel 11 in den äußeren Beutel 14 eingeschoben ist, wird die offene Stirnseite 15 des äußeren Beutels 14 mittels der festen Siegelnaht 8 verschlossen. Dabei kann auch die Begasung des Beutels 14 mit einer Schutzgasatmosphäre vorgenommen werden, wenn die Art des Lebensmittels 2 dies erfordert. Folglich umgibt der äußere Beutel 14 den inneren Beutel 11 vollständig und die in den inneren Beutel 11 eingelagerten Lebensmittel 2 sind vor Sauerstoff, Feuchtigkeit und Schadstoffen aus der Umgebung durch den Aufbau des Beutels 14 geschützt, so dass Schadstoffe, Bakterien, Vieren oder dgl. an die Lebensmittel 2 nicht gelangen können.After the inner bag 11 is inserted into the outer bag 14, the open end face 15 of the outer bag 14 is closed by means of the solid sealing seam 8. In this case, the fumigation of the bag 14 can be made with a protective gas atmosphere, if the nature of the food 2 requires it. Consequently, the outer bag 14 completely surrounds the inner bag 11 and the food 2 stored in the inner bag 11 is protected from oxygen, moisture and pollutants from the environment by the structure of the bag 14, so that pollutants, bacteria, viruses or the like the food 2 can not get.

Aus Figur 2b ist die fertig gestellte Verpackung 1 zu entnehmen. Der innere Beutel 11 ist in dem äußeren Beutel 14 eingesteckt. Um die Konturen der Verpackung 1 ästhetisch zu verbessern, ist sowohl bei dem inneren als auch bei dem äußeren Beutel 11 bzw. 14 eine weitere Folie 16 vorgesehen, durch die ein Boden für den jeweiligen inneren bzw. äußeren Beutel 11, 14 geschaffen ist. Dies vergrößert zudem das Volumen der Verpackung 1.Out FIG. 2b is the finished packaging 1 to remove. The inner bag 11 is inserted in the outer bag 14. To the contours of the packaging 1 To improve aesthetically, a further film 16 is provided both in the inner and in the outer bag 11 or 14, through which a bottom for the respective inner or outer bag 11, 14 is provided. This also increases the volume of the package 1.

Insbesondere der Figur 3 ist zu entnehmen, dass an dem Boden 16 eine Lasche 17 fest angebracht ist, in die eine Öse 18 eingearbeitet ist. Die Öse 18 dient beispielsweise als Aufreißhilfe, um den Boden 16 von dem inneren Beutel 11 zu trennen und den Inhalt des Beutels 11 frei zugänglich zu geben.In particular the FIG. 3 It can be seen that at the bottom 16 a tab 17 is fixedly mounted, in which an eyelet 18 is incorporated. The eyelet 18 serves for example as a tear-open to separate the bottom 16 of the inner bag 11 and to give the contents of the bag 11 freely accessible.

Des Weiteren kann Figur 3 entnommen werden, dass der innere Beutel 11 mittels einer festen Verbindungs-Siegelnaht 20 an der Innenseite des äußeren Beutels 14 angeschweißt ist, so dass die Position des inneren Beutels 11 bezüglich des äußeren Beutels 14 lageorientiert und ein Verrutschen des inneren Beutels 11 nicht möglich ist.Furthermore, can FIG. 3 it can be seen that the inner bag 11 is welded to the inside of the outer bag 14 by means of a firm connection sealing seam 20, so that the position of the inner bag 11 with respect to the outer bag 14 is position-oriented and slippage of the inner bag 11 is not possible.

Wenn nunmehr der Benutzer an die in der Verpackung 1 eingelagerten Lebensmittels 2 gelangen möchte, ist von diesem zunächst zu entscheiden, ob die Lebensmittel 2 kalt oder aufgewärmt konsumiert werden.
Sollte der Benutzer sich entschließen, die Lebensmittel 2 kalt verzehren zu wollen, kann der äußere Beutel 14 über eine oberhalb der Verbindungs-Siegelnaht 20 eingearbeitete Perforationsnaht 19' aufgerissen werden. Zwischen den beiden freien Enden der ursprünglichen Folie 6 ist eine peelfähige Siegelnaht 9 vorgesehen, durch die der innere Beutel 11 in diesem Bereich verschlossen ist. Nach dem Abreißen des oberen Teils des äußeren Beutels 14 kann der innere Beutel 11 in diesem Bereich auseinander gezogen werden, so dass die in dem inneren Beutel 11 eingebrachten Lebensmittel 2 frei zugänglich sind.Now, if the user wants to get to the stored in the package 1 food 2, this is first to decide whether the food 2 are consumed cold or warmed up.
If the user decides to eat the food 2 cold, the outer bag 14 can be torn open by means of a perforation seam 19 'incorporated above the connecting seam 20. Between the two free ends of the original film 6, a peelable sealing seam 9 is provided, through which the inner bag 11 is closed in this area. After the upper part of the outer bag 14 has been torn off, the inner bag 11 can be pulled apart in this area so that the foodstuffs 2 introduced into the inner bag 11 are freely accessible.

Sollte sich der Benutzer dazu entschließen, die eingelagerten Lebensmittel 2 beispielsweise in einem Heißwasserbad zu garen, ist es erforderlich, einen Teil des äußeren Beutels 14 von dem inneren Beutel 11 zu lösen. Zu diesem Zweck ist unterhalb der Verbindungs-Siegelnaht 20 in die Wand des äußeren Beutels 14 eine Perforation 19" eingearbeitet.Should the user decide to cook the stored food 2, for example, in a hot water bath, it is necessary to detach part of the outer bag 14 from the inner bag 11. For this purpose, a perforation 19 "is incorporated below the connecting sealing seam 20 in the wall of the outer bag 14.

Die Perforationen 19' und 19" sind beispielsweise mittels Laserstrahlen punktuell oder als durchgehende Naht eingearbeitet. Darüber hinaus können die Perforationen 19' und 19" linear oder wellenförmig verlaufen oder aber diese sind horizontal, vertikal oder geneigt verlaufend ausgerichtet. Dies hängt im Wesentlichen davon ab, welche Lebensmittel 2 durch die Verpackung 1 aufbewahrt werden.The perforations 19 'and 19 "are incorporated, for example, by means of laser beams selectively or as a continuous seam Moreover, the perforations 19' and 19" can extend in a linear or wavy manner or they can be aligned horizontally, vertically or inclined. This essentially depends on which foods 2 are stored by the package 1.

Wird der äußere Beutel 14 durch Auftrennen der Perforationsnaht 19" von dem inneren Beutel 11 abgetrennt, ist dieser frei zugänglich. Ein Teil des äußeren Beutels 14 ist jedoch über die Verbindungs-Siegelnaht 20 nach wie vor fest mit dem inneren Beutel 11 verbunden. Dieser nach oben abstehende Teilbereich des vormaligen äußeren Beutels 14 dient als Handhabungshilfe, um den inneren Beutel 11 und die darin eingelagerten Lebensmittel 2 in ein Heißwasserbad oder in eine Mikrowelle abzustellen. Nach dem Kochen, Garen oder Erhitzen der Lebensmittel 2 sind diese problemlos transportierbar, da die Wärmestrahlen der Lebensmittel 2 weit entfernt von der Haltetasche des äußeren Beutels 14 verlaufen.If the outer bag 14 is separated from the inner bag 11 by separating the perforation seam 19 ", it is freely accessible, but a part of the outer bag 14 is still firmly connected to the inner bag 11 via the connecting seam 20 The above-protruding portion of the former outer bag 14 serves as a handling aid for placing the inner bag 11 and the food 2 stored therein in a hot water bath or in a microwave oven the food 2 far away from the retaining pocket of the outer bag 14.

Sobald der Erhitzungsvorgang für das Lebensmittel 2 abgeschlossen ist, kann nämlich der Benutzer den inneren Beutel 11 über die nach oben abstehende Lasche des äußeren Beutels 14 aus dem Heißwasserbad entnehmen. Der innere Beutel 11 kann dann durch Ziehen an der Lasche 17 geöffnet werden, so dass die Lebensmittel 2 frei zugänglich sind und nicht vereinzelt aus dem Heißwasserbad entnommen werden müssen. Alternativ kann die Handhabungshilfe an der Perforationsnaht 19' abgetrennt werden und die peelfähige Siegelnaht 9 des Innenbeutels geöffnet werden, wie bereits für die Entnahme des Labensmittels 2 in kaltem Zustand beschrieben.Namely, once the heating operation for the food 2 is completed, the user can take out the inner bag 11 from the hot water bath via the upwardly protruding tab of the outer bag 14. The inner bag 11 can then be opened by pulling on the tab 17, so that the food 2 are freely accessible and do not have to be removed from the hot water bath sporadically. Alternatively, the handling aid can be separated at the perforation seam 19 'and the peelable sealed seam 9 of the inner bag can be opened, as already described for the removal of the rinsing agent 2 in the cold state.

In Figur 4 ist gezeigt, dass der innere Beutel 11 unverschlossen und ohne die Folie 16, die den Boden bildet, ausgestaltet ist. Bei einer solchen Ausgestaltung des inneren Beutels 11 hat sich als besonders vorteilhaft herausgestellt, dass der Benutzer entweder die Perforationsnaht 19' aufzureißen hat, um unmittelbar an die eingefüllten Lebensmittel 2 zu gelangen oder aber die Perforationsnaht 19" aufreißt, um den äußeren Beutel 14 von dem inneren Beutel teilweise abzutrennen, so dass die eingelagerten Lebensmittel 2 in ein Warmwasserbad gemeinsam mit dem inneren Beutel 11 eingefüllt werden können.In FIG. 4 It is shown that the inner bag 11 is designed unlocked and without the film 16 forming the bottom. In such an embodiment of the inner bag 11 has been found to be particularly advantageous that the user has either the perforation 19 'tear open to get directly to the filled food 2 or the perforation 19 "ruptures to the outer bag 14 of the Partial separation of the inner bag, so that the stored food 2 can be filled in a hot water bath together with the inner bag 11.

Auch der zweite Beutel 14 kann ohne weitere Vorkehrung zur Aufbewahrung von Lebensmittel 2 verwendet werden, die demnach zwischen dem ersten und dem zweiten Beutel 11, 14 eingefüllt sind.Also, the second bag 14 can be used without further provision for the storage of food 2, which are thus filled between the first and the second bag 11, 14.
