Definitions
- the present invention relates to a bag or a container for the storage and preparation of food, with a bag body formed from at least two layers.
- bags made of plastic film in particular made of heat-set PET or a special polyamide, which are used as Brat zucchini use and are smooth and not adhesive on its inside.
- a separate closure such as a clip or clamp.
- Conventional biaxially oriented and heat-set PET films can not be sealed by heated bars, but an additional sealing layer must be provided for this purpose. Therefore, such bags are usually produced by the separation welding process, which is why no production of the bag on a roll is possible, since the webs must always be severed.
- the GB 1 503 913 discloses a packaging made of a composite material, wherein on one side of the packaging an aluminum foil is connected via an adhesive layer to a layer of polyethylene. On a second side, a paper is glued to an aluminum foil, which in turn is bonded to a layer of polyethylene. Due to the air-permeable design of the composite material, this can be used as packaging for materials with odors.
- the US 4 571 337 discloses a pouch having an outer layer of paper and an inner layer of a polyester film. A coating is applied to the inner film which can be activated by heat and pressure to seal two inner layers together.
- the use of paper is, however at higher temperatures because of the flammability of the paper problematic.
- Made of polyamide bags are also relatively stiff and are softer by water absorption and are therefore less suitable for freezing, since they can adhere to the frozen food.
- the bags When used as a roasting bag, the bags must then be perforated by the user, for example by cutting with a pair of scissors to prevent accidental bursting by the forming internal pressure when heated.
- the layers of the bag body are formed of a composite material with an inner layer of plastic suitable for food contact and an outer layer of a metal foil.
- the inside is acid and corrosion resistant, in contrast to pure aluminum foil.
- the composite material is malleable by the outer layer of metal foil, i. the user can deform the material so that it remains largely in the deformed position. This can be used to close the bag opening by screwing, folding or flanging tightly and to use the bag as a frying bag.
- the composite material can be processed in a simple manner, since it has surprisingly been found that the composite material, for example made of aluminum and biaxially oriented PET, is heat-sealable. Accordingly, on conventional bag machines, sealing edge bags with as many seams as desired can be produced on a roll or as a single bag.
- the inner layer is glued to the outer layer. As a result, detachment of the inner layer from the outer layer is reliably avoided.
- the composite material has a heat resistance up to 200 ° C, in particular up to 220 ° C, on. This allows the bag to be used to cook food in the oven.
- the layers of the bag are glued or welded together at the edge at least partially at seams and on one side a bag opening is formed. This allows the bag to be made from two superimposed layers.
- the outer layer used is preferably aluminum foil, which is easily foldable and has good formability.
- the thickness of the outer layer can be between 2 ⁇ m to 20 ⁇ m, in particular 5 to 10 ⁇ m.
- the inner layer of the composite material consists of plastic film, preferably of PTFE, PET, PSU, PMP, PEEK and / or PA. Other, suitable for food contact plastic materials can be used.
- the inner layer preferably has a thickness of 2 ⁇ m to 15 ⁇ m, in particular 3 to 7 ⁇ m. In this case, the inner layer may be thinner than the outer layer.
- the seams of the bag preferably have a seam strength of more than 4 N / cm. This produces a tear-resistant bag that can be easily used in the home.
- the composite material is preferably foldable.
- Foldable in this context means that the ductility is such that after folding of the composite material, the material substantially remains in a folded position and is not elastically moved back to a starting position.
- the inner layer is coated on the side facing inwards with an anti-adhesive agent, in particular silicone.
- an anti-adhesive agent in particular silicone.
- the bag is formed as a closed package in which the bag opening is closed, optionally by a seam or a separate Closure element, for example an adhesive label.
- a material to be heated in particular a food, is preferably arranged. This allows the bag to be placed directly on a hotplate to heat the material.
- a use of a bag as a cooking vessel for storage on a stove top, in particular an induction cooker provided.
- the advantage can be used that the bag is used as a cooking vessel and has only a small mass. In comparison with commercial cooking pots, it takes a relatively long time until the bottom has warmed up and then the filled food is heated. By heating the material contained in the bag, the warm-up process is significantly shortened and also the bag can be used as an industrially fillable packaging. It is of course also possible that a bag is filled by the user himself for the subsequent preparation of food.
- FIG. 1 a bag 1 or a container is shown, which is formed from a bag body of two superimposed layers, which are connected to each other at opposite longitudinal sides by a strip-shaped sealing layer 5. At a front edge a bottom fold 4 is provided, which connects the two layers together. At the opposite side of the bottom fold 4 a bag opening 3 is formed for filling the bag 1.

- Two adjacent bag bodies 2 are held together in the region of a longitudinal sealing edge layer 5 via a perforation and can be released by severing the perforation 6.
- the bags 1 can be coiled up on a roll and then torn off by the user.
- the bags 1, 1 'and 1 each consist of two layers of a composite material, wherein a plastic film is provided as the inner layer, which is permanently connected to an outer layer, for example by gluing has a thickness of between 2 ⁇ m to 20 ⁇ m, in particular 5 to 10 ⁇ m, and the layer of composite material may also have more than two layers.
- any adhesive suitable for bonding the plastic film to the backsheet may be used to provide a stable bond between the backsheet and the backsheet under the expected thermal and mechanical conditions.
- two- or multi-component systems or hot melt adhesives are used.
- a polyurethane adhesive can be used, which is applied, for example, in an amount of 2 to 5 g / m 2 .
- the inner layer of plastic material is suitable for food contact and preferably heat resistant up to a range of 220 ° C.
- the inner layer may have a thickness between 2 microns to 15 microns, in particular 3 to 7 microns, and thus be thinner than the outer layer.

Description
Die vorliegende Erfindung betrifft einen Beutel oder einen Behälter für die Aufbewahrung und Zubereitung von Lebensmitteln, mit einem aus mindestens zwei Lagen gebildeten Beutelkörper.The present invention relates to a bag or a container for the storage and preparation of food, with a bag body formed from at least two layers.
Es gibt Beutel aus Kunststofffolie, insbesondere aus thermofixiertem PET oder einem speziellen Polyamid, die als Bratbeutel Verwendung finden und an ihrer Innenseite glatt und nicht klebend ausgebildet sind. Um diese Beutel zu verschließen, ist es notwendig, die Beutelöffnung mit einem separaten Verschluss zu versehen, beispielsweise einem Clip oder einer Klemme. Herkömmlich biaxial orientierte und thermofixierte PET-Folien lassen sich nicht durch beheizte Balken siegeln, sondern es muss dazu eine zusätzliche Siegelschicht vorgesehen sein. Daher werden solche Beutel meist im Trennschweißverfahren hergestellt, weshalb keine Fertigung der Beutel auf einer Rolle möglich ist, da die Bahnen immer durchtrennt werden müssen.There are bags made of plastic film, in particular made of heat-set PET or a special polyamide, which are used as Bratbeutel use and are smooth and not adhesive on its inside. To close these pouches, it is necessary to provide the pouch opening with a separate closure, such as a clip or clamp. Conventional biaxially oriented and heat-set PET films can not be sealed by heated bars, but an additional sealing layer must be provided for this purpose. Therefore, such bags are usually produced by the separation welding process, which is why no production of the bag on a roll is possible, since the webs must always be severed.
Die
Die
Aus Polyamid hergestellte Beutel sind zudem relativ steif und werden durch Wasseraufnahme weicher und eignen sich daher weniger gut zum Einfrieren, da sie an dem Gefriergut anhaften können. Beim Einsatz als Bratbeutel müssen die Beutel dann durch den Anwender perforiert werden, beispielsweise durch Einschneiden mit einer Schere, um ein versehentliches Platzen durch den sich bildenden Innendruck beim Erhitzen zu verhindern.Made of polyamide bags are also relatively stiff and are softer by water absorption and are therefore less suitable for freezing, since they can adhere to the frozen food. When used as a roasting bag, the bags must then be perforated by the user, for example by cutting with a pair of scissors to prevent accidental bursting by the forming internal pressure when heated.
Es ist daher Aufgabe der vorliegenden Erfindung, einen Beutel für die Aufbewahrung und Zubereitung von Lebensmitteln zu schaffen, der einfach herstellbar ist und eine optimierte Handhabung gewährleistet, sowie zum Erhitzen von Lebensmitteln eingesetzt werden kann.It is therefore an object of the present invention to provide a bag for the storage and preparation of food, which is easy to prepare and ensures optimized handling, and can be used for heating food.
Zur Lösung dieser Aufgabe wird ein Beutel oder ein Behälter mit den Merkmalen des Anspruches 1 geschaffen.To solve this problem, a bag or container with the features of
Erfindungsgemäß sind die Lagen des Beutelkörpers aus einem Verbundmaterial mit einer für den Lebensmittelkontakt geeigneten Innenlage aus Kunststoff und einer Außenlage aus einer Metallfolie gebildet. Dadurch ist die Innenseite im Gegensatz zu reinen Aluminiumfolien säure- und korrosionsbeständig. Das Verbundmaterial ist jedoch durch die Außenlage aus einer Metallfolie formbar, d.h. der Benutzer kann das Material so verformen, dass dieses weitgehend in der verformten Lage verbleibt. Dies kann dazu genutzt werden, die Beutelöffnung durch ein Eindrehen, Falten oder Um- bördeln weitgehend dicht zu verschließen und den Beutel als Bratbeutel einzusetzen. Zudem lässt sich das Verbundmaterial auf einfache Weise verarbeiten, da sich überraschend herausgestellt hat, dass das Verbundmaterial, beispielsweise aus Aluminium und biaxial orientiertem PET heißsiegelfähig ist. Dementsprechend können auf herkömmlichen Beutelmaschinen Siegelrandbeutel mit beliebig vielen Nähten auf einer Rolle oder als Einzelbeutel hergestellt werden.According to the invention, the layers of the bag body are formed of a composite material with an inner layer of plastic suitable for food contact and an outer layer of a metal foil. As a result, the inside is acid and corrosion resistant, in contrast to pure aluminum foil. However, the composite material is malleable by the outer layer of metal foil, i. the user can deform the material so that it remains largely in the deformed position. This can be used to close the bag opening by screwing, folding or flanging tightly and to use the bag as a frying bag. In addition, the composite material can be processed in a simple manner, since it has surprisingly been found that the composite material, for example made of aluminum and biaxially oriented PET, is heat-sealable. Accordingly, on conventional bag machines, sealing edge bags with as many seams as desired can be produced on a roll or as a single bag.
Gemäß der Erfindung ist die Innenlage mit der Außenlage verklebt. Dadurch wird ein Ablösen der Innenlage von der Außenlage sicher vermieden.According to the invention, the inner layer is glued to the outer layer. As a result, detachment of the inner layer from the outer layer is reliably avoided.
Ferner ist auch die direkte Aufbringung eines temperaturfesten Kunststoffes als Innenlage aus der Schmelze heraus möglich, beispielsweise durch Extrusionsbeschichtung. Auf diese Weise ist der Einsatz eines Klebers nicht mehr erforderlich.Furthermore, the direct application of a temperature-resistant plastic as an inner layer of the melt out is possible, for example by extrusion coating. In this way, the use of an adhesive is no longer necessary.
Um den Beutel auch als Bratbeutel einsetzen zu können, weist das Verbundmaterial eine Hitzebeständigkeit bis 200° C, insbesondere bis 220° C, auf. Dadurch kann der Beutel zum Garen von Lebensmitteln im Backofen verwendet werden.In order to use the bag as a frying bag, the composite material has a heat resistance up to 200 ° C, in particular up to 220 ° C, on. This allows the bag to be used to cook food in the oven.
Vorzugsweise sind die Lagen des Beutels randseitig zumindest teilweise an Nähten miteinander verklebt oder verschweißt und an einer Seite ist eine Beutelöffnung ausgebildet. Dadurch kann der Beutel aus zwei übereinander gelegten Lagen hergestellt werden.Preferably, the layers of the bag are glued or welded together at the edge at least partially at seams and on one side a bag opening is formed. This allows the bag to be made from two superimposed layers.
Als Außenlage wird vorzugsweise Aluminiumfolie eingesetzt, die leicht faltbar ist und eine gute Formbarkeit besitzt. Die Dicke der Außenlage kann dabei zwischen 2 µm bis 20 µm, insbesondere 5 bis 10 µm, betragen.The outer layer used is preferably aluminum foil, which is easily foldable and has good formability. The thickness of the outer layer can be between 2 μm to 20 μm, in particular 5 to 10 μm.
Die Innenlage des Verbundmaterials besteht aus Kunststofffolie, vorzugsweise aus PTFE, PET, PSU, PMP, PEEK und/oder PA. Auch andere, für den Lebensmittelkontakt geeignete Kunststoffmaterialien können eingesetzt werden. Die Innenlage weist vorzugsweise eine Dicke von 2 µm bis 15 µm, insbesondere 3 bis 7 µm, auf. Dabei kann die Innenlage dünner als die Außenlage ausgebildet sein.The inner layer of the composite material consists of plastic film, preferably of PTFE, PET, PSU, PMP, PEEK and / or PA. Other, suitable for food contact plastic materials can be used. The inner layer preferably has a thickness of 2 μm to 15 μm, in particular 3 to 7 μm. In this case, the inner layer may be thinner than the outer layer.
Die Nähte des Beutels weisen vorzugsweise eine Nahtfestigkeit von mehr als 4 N/cm auf. Dadurch wird ein reißfester Beutel hergestellt, der im Haushalt einfach eingesetzt werden kann.The seams of the bag preferably have a seam strength of more than 4 N / cm. This produces a tear-resistant bag that can be easily used in the home.
Das Verbundmaterial ist vorzugsweise faltbar ausgebildet. Mit faltbar ist in diesem Zusammenhang gemeint, dass die Duktilität so ausgebildet ist, dass nach einem Falten des Verbundmaterials das Material im Wesentlichen in einer gefalteten Position verbleibt und nicht elastisch in eine Ausgangslage zurückbewegt wird.The composite material is preferably foldable. Foldable in this context means that the ductility is such that after folding of the composite material, the material substantially remains in a folded position and is not elastically moved back to a starting position.
Gemäß einer weiteren Ausgestaltung der Erfindung ist die Innenlage auf der nach innen gewandten Seite mit einem Antihaftmittel, insbesondere Silikon, beschichtet. Dadurch wird ein Anhaften des Verbundmaterials an dem Lebensmittel beim Einfrieren oder beim Garen vermieden.According to a further embodiment of the invention, the inner layer is coated on the side facing inwards with an anti-adhesive agent, in particular silicone. As a result, adhesion of the composite material to the food during freezing or cooking is avoided.
Vorzugsweise ist der Beutel als geschlossene Verpackung ausgebildet, bei der die Beutelöffnung verschlossen ist, wahlweise durch eine Naht oder ein gesondertes Verschlusselement, beispielsweise ein Klebeetikett. In der geschlossenen Verpackung ist vorzugsweise ein zu erwärmendes Material, insbesondere ein Lebensmittel, angeordnet. Dadurch kann der Beutel zum Erwärmen des Materials direkt auf eine Herdplatte gelegt werden.Preferably, the bag is formed as a closed package in which the bag opening is closed, optionally by a seam or a separate Closure element, for example an adhesive label. In the closed packaging, a material to be heated, in particular a food, is preferably arranged. This allows the bag to be placed directly on a hotplate to heat the material.
Erfindungsgemäß wird auch eine Verwendung eines Beutels als Kochgefäß zur Ablage auf einer Herdplatte, insbesondere einer Induktionsherdplatte, bereitgestellt. Dadurch kann der Vorteil genutzt werden, dass der Beutel als Kochgefäß eingesetzt wird und nur eine geringe Masse aufweist. Im Vergleich mit handelsüblichen Kochtöpfen dauert es zunächst relativ lange, bis sich der Boden erwärmt hat und dann die eingefüllten Speisen erwärmt werden. Durch die Erwärmung des in dem Beutel enthaltenen Materials wird der Aufwärmvorgang deutlich verkürzt und zudem kann der Beutel auch als industriell befüllbare Verpackung eingesetzt werden. Es ist natürlich auch möglich, dass ein Beutel vom Anwender selbst zur anschließenden Zubereitung von Speisen gefüllt wird.According to the invention, a use of a bag as a cooking vessel for storage on a stove top, in particular an induction cooker, provided. As a result, the advantage can be used that the bag is used as a cooking vessel and has only a small mass. In comparison with commercial cooking pots, it takes a relatively long time until the bottom has warmed up and then the filled food is heated. By heating the material contained in the bag, the warm-up process is significantly shortened and also the bag can be used as an industrially fillable packaging. It is of course also possible that a bag is filled by the user himself for the subsequent preparation of food.

Die Beutel 1, 1' und 1" bestehen jeweils aus zwei Lagen aus einem Verbundmaterial, wobei als Innenlage eine Kunststofffolie vorgesehen ist, die mit einer Außenlage unlösbar verbunden ist, beispielsweise durch Verkleben. Die Außenlage besteht aus einer Metallfolie, insbesondere einer Aluminiumfolie, und weist eine Dicke zwischen 2 µm bis 20 µm, insbesondere 5 bis 10 µm, auf. Zudem kann die Lage aus Verbundmaterial auch mehr als zwei Schichten aufweisen.The
Als Kleber kann jedes Klebemittel eingesetzt werden, das zum Verbinden der Kunststofffolie mit der Außenlage geeignet ist, damit eine stabile Verbindung zwischen der Innenlage und der Außenlage unter den zu erwartenden thermischen und mechanischen Bedingungen erhalten wird. Vorzugsweise werden Zwei-oder Mehrkomponentensysteme oder Schmelzkleber eingesetzt. Insbesondere kann ein Polyurethankleber eingesetzt werden, der beispielsweise in einer Menge von 2 bis 5 g/m2 aufgetragen wird.As the adhesive, any adhesive suitable for bonding the plastic film to the backsheet may be used to provide a stable bond between the backsheet and the backsheet under the expected thermal and mechanical conditions. Preferably, two- or multi-component systems or hot melt adhesives are used. In particular, a polyurethane adhesive can be used, which is applied, for example, in an amount of 2 to 5 g / m 2 .
Die Innenlage aus Kunststoffmaterial ist für den Lebensmittelkontakt geeignet und vorzugsweise bis zu einem Bereich von 220° C hitzebeständig. Die Innenlage kann dabei eine Dicke zwischen 2 µm bis 15 µm, insbesondere 3 bis 7 µm, aufweisen und somit dünner ausgebildet sein als die Außenlage. Die Kunststofffolie kann insbesondere aus PTFE (Polytetrafluorethylen), PET (Polyethylenterephthalat), PSU (Polysulfon), PEEK (Polyetheretherketon), PMP (Polymethylpenten), PA (Polyamid) oder einem anderen geeigneten Kunststoff oder einer Mischung dieser Materialien bestehen. Zudem ist es möglich, die Innenlage an der Innenseite antihaftend zu beschichten, beispielsweise mit Silikon, um ein Anhaften von Lebensmitteln zu vermeiden.The inner layer of plastic material is suitable for food contact and preferably heat resistant up to a range of 220 ° C. The inner layer may have a thickness between 2 microns to 15 microns, in particular 3 to 7 microns, and thus be thinner than the outer layer. In particular, the plastic film may consist of PTFE (polytetrafluoroethylene), PET (polyethylene terephthalate), PSU (polysulfone), PEEK (polyether ether ketone), PMP (polymethylpentene), PA (polyamide) or any other suitable plastic or mixture of these materials. In addition, it is possible to coat the inner layer on the inside non-stick, for example, with silicone, in order to avoid sticking of food.
Durch die dünne Ausbildung der Innenlage lässt sich das Verbundmaterial gut verformen und falten, so dass sich das Verbundmaterial gut an das Füllgut im Beutel 1, 1', 1" anschmiegen kann. Ferner kann der Anwender den Beutel 1, 1', 1" leicht durch Falten, Einwickeln oder Umbördeln der Beutelöffnung 3 verschließen.Due to the thin formation of the inner layer, the composite material can be deformed and folded well, so that the composite material can cling well to the contents in the
Das Verbundmaterial weist zudem eine ausreichende mechanische Stabilität bei Einfriertemperaturen bis etwa -20° C auf und die Beutel 1, 1', 1" können mit den Lebensmitteln unmittelbar aus dem Gefrierfach in einen Backofen gelegt werden, damit der Beutel 1, 1', 1" dort erhitzt werden kann.The composite material also has sufficient mechanical stability at freezing temperatures up to about -20 ° C and the
In den dargestellten Ausführungsbeispielen ist der Beutel 1, 1', 1" mit einer glatten Beutelöffnung 3 gezeigt, bei der die beiden Lagen baugleich aufeinander gelegt sind. Es ist natürlich auch möglich, eine Lage des Beutelkörpers 2 länger auszubilden, die dann als Lasche um die andere Lage gefaltet werden kann.In the exemplary embodiments shown, the
Zudem kann der Beutel aus dem Verbundmaterial weitgehend frei in der Form und in der Größe gestaltet werden, um ihn für unterschiedliche Anwendungsfälle einsetzen zu können.In addition, the bag can be made of the composite material largely free in shape and in size to use it for different applications can.

Optional kann der erfindungsgemäße Beutel auch in einem nichtleitenden Behältnis, beispielsweise einer Glas- oder Keramikschale, auf das Induktionsfeld gestellt werden, da das Magnetfeld des Induktionsofens die Materialien im Wesentlichen ohne Verluste durchdringt.The bag according to the invention is preferably used for heating materials, in particular foods. In this case, the bag can be placed on a
Das erfindungsgemäße Verbundmaterial besteht vorzugsweise aus einer Aluminiumfolie, die eine Schichtdicke zwischen 6 und 10 µm aufweist, die über einen Polyurethankleber mit einer Kunststofffolie aus PET verklebt ist. Die Kunststofffolie weist eine Dicke zwischen 4 und 8 µm, insbesondere zwischen 5 bis 7 µm, auf. Es ist für das Verkleben der Kunststofffolie nur ein geringer Klebemitteleinsatz erforderlich, beispielsweise im Bereich zwischen 2 bis 4 g/m2.The composite material according to the invention preferably consists of an aluminum foil which has a layer thickness of between 6 and 10 μm, which is glued over a polyurethane adhesive to a plastic film of PET. The plastic film has a thickness between 4 and 8 microns, in particular between 5 to 7 microns, on. Only a small amount of adhesive is required for bonding the plastic film, for example in the range between 2 to 4 g / m 2 .
Soll der Beutel als halbstarrer Behälter ausgebildet sein, ist eine größere Schichtdicke vorteilhaft, wobei der Gesamtverbund vorzugsweise eine Dicke zwischen 40 bis 80 µm aufweist.If the bag is to be designed as a semi-rigid container, a larger layer thickness is advantageous, the overall composite preferably having a thickness of between 40 and 80 μm.
