Abstract

The application of a container (1) consisting of a deep-drawn foil (2) welded airtight to a lid of two-layer plastic foil (3) covers deep-freezing and/or storing and/or thawing-out and/or heating and/or cooking of foodstuffs (5).

Description

Die Erfindung betrifft die Verwendung eines Behältnisses aus einer Tiefziehfolie, die mittels eines Deckels aus einer zweischichtigen Kunststofffolie luftdicht verschweißt ist.The The invention relates to the use of a container made of thermoforming film, the airtight by means of a lid made of a two-layer plastic film welded is.

Derartige Behältnisse werden in der Lebensmittelindustrie zum Verpacken von im Wesentlichen Wurst- und Käsewaren verwendet. Durch ein Abreißen des verschweißten Deckels von der Tiefziehfolie, wobei sich üblicherweise die zweischichtige Kunststofffolie voneinander trennt, wird das Behältnis geöffnet. Dazu muss eine große äußere Kraft aufgewendet werden.such containers are used in the food industry for the packaging of essentially sausage and cheese goods used. By tearing off of the welded Lids from the thermoforming sheet, which is usually the two-layer Plastic film separates, the container is opened. This requires a great external force be spent.

Auf dem Tiefkühlsektor werden üblicherweise Tiefkühlbeutel verwendet, deren Wände nach Befüllung im Bereich der Öffnung der Beutel verschweißt werden. Sollen die tiefgefrorenen Lebensmittel in dem Tiefkühlbeutel aufgetaut, erhitzt oder gegart werden, entstehen bei der Erhitzung bzw. beim Garungsprozess Gase und Wasserdampf, die regelmäßig dazu führen, dass der Gefrierbeutel unkontrollierbar platzt. Bei einem Auftauen, Erhitzen bzw. Garen in einer Mikrowelle spritzen die Lebensmittel beim Platzen der Verpackung in den Mikrowelleninnenraum, welcher aufwendig zu reinigen ist.On the frozen sector become common Freezer bag used their walls after filling in the area of the opening the bag is welded become. Shall the frozen foods in the frozen bag thawed, heated or cooked, arise during heating or during the cooking process gases and water vapor, which regularly to lead, that the freezer bag bursts uncontrollably. When thawing, Heating or cooking in a microwave inject the food when bursting the packaging in the microwave interior, which is expensive to clean.

Es wurde auch schon vorgeschlagen, bevor das tiefgefrorene Lebensmittel in dem Tiefkühlbeutel in die Mikrowelle bzw. in den Backofen geschoben wird, in die Verpackungsfolie Löcher einzubringen, damit die Gase entweichen können. Derartig gegarte Lebensmittel verlieren jedoch an Geschmack.It has also been suggested before the frozen food in the frozen bag in the microwave or in the oven is pushed into the packaging film holes so that the gases can escape. Such cooked food However, they lose their taste.

Als weiterer Nachteil ergibt sich, dass sich die Kochbeutel bei größerer Hitze verformen und chemisch verändern wodurch der Geschmack des zu erhitzendes Lebensmittels bzw. Gargutes negativ beeinflusst werden kann.When Another disadvantage is that the cooking bag at greater heat deform and chemically change whereby the taste of the food or cooking food to be heated can be negatively influenced.

Der Erfindung liegt die Aufgabe zugrunde, ein Behältnis für Lebensmittel aufzuzeigen, in welchem diese tiefgefroren werden und/oder tiefgefroren gelagert werden können und/oder welches zum Auftauen und/oder Erhitzen und/oder Garen verwendet werden kann, ohne dass es zu einem unkontrollierten Platzen des Behältnisses kommt.Of the Invention has for its object to provide a container for food, in which they are frozen and / or stored frozen can be and / or which are used for thawing and / or heating and / or cooking can, without causing an uncontrolled bursting of the container comes.

Dazu wird vorgeschlagen, dass ein Behältnis aus einer Tiefziehfolie, die mittels eines Deckels aus einer zweischichtigen Kunststofffolie luftdicht verschweißt ist und zum Tieffrieren und/oder Lagern von tiefgefrorenen Lebensmitteln und/oder zum Auftauen und/oder Erhitzen und/oder Garen der Lebensmittel in einem Wasserbad oder im Backofen oder in der Mikrowelle oder in einem Konfektiomat verwendet wird.To It is suggested that a container is made a thermoforming foil, which by means of a lid of a two-layer Plastic film is airtight welded and deep freezing and / or storage of frozen food and / or thawing and / or Heating and / or cooking the food in a water bath or used in the oven or in the microwave or in a confectionery machine becomes.

Die beim Auftauen, Erhitzen bzw. Garen entstehenden Gase und Wasserdämpfe bewirken, dass der Innendruck in dem Behältnis steigt. Übersteigt der Innendruck ein gewisses Maß so löst sich der Kunststoffdeckel durch den hohen Innendruck von der Tiefziehfolie. Weder die Tiefziehfolie noch der Deckel platzen dabei. Lediglich die Schweißnaht, die bei der bekannten Verwendung durch Abreißen des Deckels geöffnet wird, wird in diesem Fall durch den hohen Innendruck geöffnet. Das Lebensmittel verbleibt weiterhin in der Tiefziehfolie und tritt aus dieser nicht aus.The cause thawing, heating or cooking of gases and water vapors, that the internal pressure in the container increases. Exceeds the Internal pressure a degree so dissolves the plastic lid due to the high internal pressure of the thermoforming foil. Neither the thermoforming film nor the lid burst. Only the weld, which is opened in the known use by tearing off the lid, is opened in this case by the high internal pressure. The Food remains in the thermoforming sheet and enters not out of this.

Es hat sich bewährt, dass die Lebensmittel vakuumverpackt sind. Auch bei einer Vakuumverpackung entstehen beim Garungsprozess Gase, die zu einem hohen Druck in dem Behältnis führen, welches letztendlich zur Öffnung der Schweißnaht zwischen der Tiefziehfolie und dem Deckel führt.It has proved its worth, that the food is vacuum-packed. Even with a vacuum packaging During the cooking process, gases that generate a high pressure in the container to lead, which ultimately leads to the opening the weld between the thermoforming sheet and the lid leads.

Von Vorteil ist, wenn es sich bei der Tiefziehfolie um eine Tiefziehkochfolie handelt, die auch noch bei Temperaturen von bis zu 180° formstabil bleibt und sich chemisch nicht verändert.From The advantage is, when the thermoforming foil is a thermoforming cooking foil which is also dimensionally stable at temperatures of up to 180 ° stays and does not change chemically.

Als Deckel haben sich Verbundfolien aus Polyamid mit einer Polyolephin-Siegelschicht bewährt. Durch diese Verbundfolie ist ein sicheres Öffnen durch den Innendruck an der Schweißnaht gewährleistet. Auch diese Deckel bleiben bis zu Temperaturen von ca. 180° form- und chemisch stabil.When Lids have proven to be polyamide composite films with a polyolefin sealant layer. By This composite foil is a safe opening by the internal pressure at the weld guaranteed. These lids also remain up to temperatures of approx. 180 ° chemically stable.

Ein Ausführungsbeispiel der Erfindung wird anhand einer Zeichnung erläutert. Die Zeichnung zeigt dabei inOne embodiment The invention will be explained with reference to a drawing. The drawing shows while in

1 ein erfindungsgemäßes Behältnis im verschlossenen Zustand, und 1 a container according to the invention in the closed state, and

2 ein erfindungsgemäßes Behältnis in teilweise geöffnetem Zustand. 2 an inventive container in a partially opened state.

1 zeigt ein Behältnis 1, bestehend aus einer Tiefziehfolie 2 in Form einer Schüssel, auf die eine zweischichtige Kunststofffolie 3 als Deckel rundum an der Position 4 verschweißt ist. In der Schüssel befindet sich ein tiefgefrorenes Lebensmittel 5. 1 shows a container 1 , consisting of a thermoforming foil 2 in the form of a bowl on which a two-ply plastic film 3 as a lid all around at the position 4 is welded. In the bowl is a frozen food 5 ,

Beim Garen des Lebensmittels 5 entstehen Gase, die zu einem großen Druck im Inneren des Behältnisses 1 führen. An der Position 6 nach 2 ist die Verbindung zwischen der zweischichtigen Kunststofffolie 2 und der Verbundfolie 3 durch diesen Innendruck gelöst. Die Gase können an dieser Stelle entweichen.When cooking the food 5 Gases that generate a large pressure inside the container 1 to lead. At the position 6 to 2 is the connection between the two-layer plastic film 2 and the composite foil 3 solved by this internal pressure. The gases can escape at this point.

Das Material der Tiefziehfolie sowie der zweischichtigen Kunststofffolie 3 wird so gewählt, dass Temperaturen von bis zu 180 ° C auftreten können, ohne dass sich die Folien verformen bzw. in ihrer Zusammensetzung verändern. Die beim Garen des Lebensmittels 5 entstehenden Gase bewirken regelmäßig, kurz bevor das Lebensmittel gar ist, ein Abreißen des Deckels von der Tiefziehfolie 2 an der Position 6, welche an beliebiger Stelle der umlaufenden Schweißnaht 4 entstehen kann.The material of thermoforming film and the two-layer plastic film 3 is chosen so that temperatures of up to 180 ° C can occur without the films deforming or changing their composition. The while cooking the food 5 Resulting gases cause regularly, just before the food is cooked, a tearing of the lid of the thermoforming sheet 2 at the position 6 , which at any point of the circumferential weld 4 can arise.

Durch komplettes Entfernen der zweischichtigen Kunststofffolie 3 von der Tiefziehfolie 2, oder ein Aufschneiden des Behältnisses 1 lässt sich das gegarte Lebensmittel 5 aus dem Behältnis 1 entnehmen.By completely removing the two-layer plastic film 3 from the thermoforming foil 2 , or a slicing of the container 1 lets the cooked food 5 from the container 1 remove.
