Description
Die Erfindung betrifft eine folienartige Materialkombination zum Verpacken von Lebensmitteln, welche im verpackten Zustand in einem Mikrowellenofen oder dergleichen erhitzt werden sollen.The invention relates to a film-like Material combination for packaging food, which packed in a microwave oven or the like to be heated.
Beim Erhitzen der meisten Lebensmittel entsteht Wasserdampf, der die ungeöffnete Verpackung aus einem derartigen Material zum Platzen bringen würde. Andererseits ist es aber auch nicht möglich, die Verpackung vor dem Erhitzen zu öffnen, da dann das Füllgut austreten würde.When heating up most foods Water vapor, which is the unopened packaging from a would burst such material. On the other hand it is also not possible to remove the packaging before Open the heating, as the contents would then escape.
Der Erfindung liegt die Aufgabe zugrunde, eine Materialkombination für den genannten Zweck zu schaffen, mit der die Lebensmittel im verpackten Zustand erhitzt werden können.The invention has for its object a To create material combinations for the stated purpose, with which the food is heated in the packaged state can be.
Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß für den Verschluß der Verpackung eine Kaltkleberbeschichtung vorgesehen ist, welche mit wenigstens einer Schwachstelle versehen ist, an der beim Erhitzen entstehender Wasserdampf unter Auftrennung der Schwachstelle entweichen kann.This object is achieved in that for sealing the packaging with a cold adhesive coating is provided which has at least one vulnerability is provided, on the water vapor generated during heating can escape by separating the weak point.
Beim Beginn der Erhitzung ist die Schwachstelle noch geschlossen, so daß das Füllgut weder verunreinigt wird, noch austreten kann. Erst bei Überschreiten eines gewissen Innendrucks geht die Schwachstelle auf und läßt den Wasserdampf entweichen.The weak point is still at the start of heating closed so that the contents are neither contaminated, can still emerge. Only when a certain amount is exceeded The weak point opens up and leaves the Water vapor escape.
Bei einer streifenförmig aufgetragenen Kaltkleberbeschichtung ist es erfindungsgemäß sehr vorteilhaft, wenn die Kaltkleberbeschichtung im Bereich der Schwachstellen mit geringerer Breite ausgebildet ist.With a stripe applied Cold adhesive coating is very much according to the invention advantageous if the cold adhesive coating in the area of Vulnerabilities with a smaller width is formed.
Diese geringere Breite der streifenförmigen Kaltkleberbeschichtung reicht zum normalen Abdichten der Verpackung völlig aus, kann aber dem erhöhten Innendruck beim Entstehen von Wasserdampf nicht standhalten.This smaller width of the stripe Cold adhesive coating is sufficient for normal sealing of the Packaging completely out, but can withstand the increased internal pressure do not withstand water vapor.
Sehr vorteilhaft ist es auch, wenn erfindungsgemäß an der Außenseite des Materialaufbaus Papier vorgesehen ist, an das sich nach innen PETP anschließt, das wiederum als Träger für die Kaltkleberbeschichtung dient.It is also very advantageous if, according to the invention, the Paper is provided on the outside of the material structure which joins PETP internally, which in turn as Carrier for the cold adhesive coating is used.
Mit einer Papieraußenschicht läßt sich die insbesondere heiße Verpackung leichter handhaben.This can be done in particular with an outer paper layer easier handling of hot packaging.
In der Zeichnung ist die Erfindung anhand eines Ausführungsbeispiels veranschaulicht. Dabei zeigen:In the drawing, the invention is based on a Exemplary embodiment illustrated. Show:
Fig. 1 eine Ansicht einerMaterialkombination mit streifenförmig aufgebrachter Kaltkleberbeschichtung und Fig. 1 is a view of a combination of materials with a cold-adhesive coating applied in strips and
Fig. 2 einen Schnitt durch die Materialkombination. Fig. 2 shows a section through the combination of materials.
Mit 1 ist in Fig. 1 eine Materialkombination bezeichnet, die zum Verpacken von Lebensmitteln dient, die in einem Mikrowellenofen erhitzbar sind. Wie insbesondere aus Fig. 2 ersichtlich ist, besteht die Materialkombination aus einer Trägerschicht 2 aus Papier, auf die mit Hilfe eines Kaschierklebers 3 eine Kunststoffolie 4 aus PETP aufgebracht ist. Auf diese PETP-Schicht 4 ist ein Kaltkleber 5 streifenförmig aufgebracht, der beim Zusammenfalten eines Zuschnittes dieses Materials zu einer Verpackung aufeinander zu liegen kommt und dabei gegen sich selbst klebt. An mehreren Stellen ist der streifenförmige Kaltkleber eingeschnürt, so daß sich Schwachstellen 6 bilden, in deren Bereich nur eine verhältnismäßig schmale Kaltkleberbrücke vorhanden ist. Beim Aufeinanderfalten kommen diese schmalen Brücken aufeinander zu liegen, so daß sie in ihrer geringen Breite erhalten bleiben. 1 in FIG. 1 denotes a combination of materials that is used to pack food that can be heated in a microwave oven. As can be seen in particular from FIG. 2, the material combination consists of a carrier layer 2 made of paper, onto which a plastic film 4 made of PETP is applied with the aid of a laminating adhesive 3 . A cold adhesive 5 is applied in strips to this PETP layer 4 , which comes to lie on top of one another when a blank of this material is folded into a package and thereby adheres to itself. The strip-shaped cold glue is constricted at several points, so that weak spots 6 form, in the area of which there is only a relatively narrow cold glue bridge. When they are unfolded, these narrow bridges come to rest on one another so that their narrow width is preserved.
Wie in Fig. 2 dargestellt kann die Papierschicht 2 auf ihrer von der Kunststoffschicht abgewandten Seite mit Farbe 7 sowie einer Lackschicht 8 versehen sein, wodurch das Papier einen zusätzlichen Schutz erhält.As shown in Fig. 2, the paper layer 2 on its side facing away from the plastic layer side with paint 7, and a resist layer 8 may be provided, thereby giving a paper additional protection.
