Mehrschichtige Folie zur Wärmeversieglung eines GefäßesMulti-layer film for heat sealing a vessel
Die vorliegende Erfindung bezieht sich auf eine mehrschichtige Folie, die insbesondere zur ¥ärmeversieglung eines Gefäßes, wie eines Bechers mit Joghurt bestimmt ist,The present invention relates to a multilayer film, which is used in particular for ¥ ärmeversieglung a vessel, like a cup with yoghurt,
Es ist bekannt, daß zu diesem Zweck eine Aluminiumfolie verwendet wird, die auf der dem Gefäß zugewandten Seite mit einem Überzug bzw. einer Haut eines wärmeklebenden Firnis versehen ist, ggf. unter weiterer Einschaltung einer Schicht eines Verbindungs- bzw. Haftfirnis, der für Aluminium geeignet ist.It is known that an aluminum foil is used for this purpose is used, which is on the side facing the vessel with a coating or a skin of a heat-adhesive Varnish is provided, if necessary with the further inclusion of a layer of a connecting or adhesive varnish, the is suitable for aluminum.
Nachteilig bei einer derartigen Aluminiumfolie, die eine Dicke in der Größenordnung von 3o - ko ,U m aufweist, ist insbesondere die Verletzbarkeit durch Einstiche und Durch-A disadvantage of such an aluminum foil, which has a thickness of the order of magnitude of 3o - ko, U m, is in particular the vulnerability to punctures and punctures

Handhabung der Gefäße, mit denen sie verbunden ist, verletzt wird, was den Verlust des Inhalts des Gefäßes nach sich zieht.■ would break, and it is not uncommon for them to get through. handling the vessels to which it is connected is injured, resulting in the loss of the contents of the vessel entails.
Dieser geringe Tiiderstand der Aluminiumfolie äußert sich gleichermaßen durch ein Zerreißen in Form von Lappen beim Öffnen des Gefäßes, wodurch -■ · sich dieses langwierig gestaltet.This low resistance of the aluminum foil expresses itself equally by tearing in the form of flaps when the vessel is opened, whereby - ■ · this lengthy designed.
Um diese Nachteile zu vermeiden, wurde überlegt, die Dicke der verwendeten Aluminiumfolie zu vergrößern beispielsweise auf 5o -60 /Um. Leider erhöht ein derartiges Vorgehen den Wiederverkaufspreis der Produkte ganz beträchtlich. In order to avoid these disadvantages, consideration was given to increasing the thickness of the aluminum foil used, for example to 50 -60 / μm. Unfortunately, such an approach increases the resale price of the products quite considerably.
Die Aufgabe der vorliegenden Erfindung besteht folglich darin, einen neuen Aufbau der Abdeckungsfblie vorzuschlagen, die gleichermaßen einen großen Wiederstand gegen Durchbriiche und Zerreißen bei geringem Wiederverkauf spreis aufweist.The object of the present invention is therefore to propose a new construction of the cover sheet, which at the same time offer great resistance to breakthroughs and tearing with little resale price shows.
Durch Aufbringen eines Überzugs bzw. einer Haut von Polyester weist die erfindungsgemäße Verschlußfolie einen großen ..Widerstand gegen Zerreißen und Wegreißen auf.By applying a coating or a skin of polyester, the closure film according to the invention exhibits a great .. resistance to tearing and tearing away on.
In-dem weiterhin eine Folie aus einem zum Druck bzw. Aufprägen geeigneten Werkstoff, wie eine Aluminiumfolie oder Papierfolie, vorgesehen ist, weist die erfindungsgemäße Verschlußfolie die-selben MarkierungsmöglichkeitenIn addition, a film made of a for printing or Embossing suitable material, such as an aluminum foil or paper foil, is provided, has the inventive Sealing film the same marking options

auf wie die bekannten Verschlußfolien, die gänzlich aus Aluminium bestehen, wobei jedoch die Dicke des Aluminiums geringer ist und auf weniger als 2o M. m reduziert werden kann oder wobei das Aluminium vollständig ersetzt werden kann durch ein weniger kostspieliges Material, wie durch Papier. Die Markierung kann nun durch Farbaufprägen bzw. Farbdruck verwirklicht werden oder durch Prägen, da das die Folie bildende Material hierfür geeignet ist, wobei die Polyesterhaut die Prägemöglichkeiten aufgrund ihrer geringen Dicke nicht beeinträchtigt, die ganz allgemein kleiner als 2o Αλ. m ist.as that of the known closure films consist entirely of aluminum, but the thickness of aluminum is less and can be reduced to less than 2o M. m or wherein the aluminum can be completely replaced by a less expensive material, such as by paper. The marking can now be realized by color stamping or color printing or by stamping, since the material forming the film is suitable for this, the polyester skin not impairing the stamping options due to its small thickness, which is generally smaller than 2o Αλ. damn.
Die aus einem zum Druck geeigneten Material bestehende Folie, die formscüLüssig an allen Punkten mit der Polyesterhaut verbunden ist, erleichtert außerdem das Ausschneiden bzw. Stanzen des Aufbaues, wenn er am Gefäß aufgebracht ist. In der Tat bietet sich diese Folie mehr zum Ergreifen beim Aufschneiden mit dem Messer an, als das Polyester und ist besser geeignet als dieses beim Durchschneiden; wenn man nämlich die erfindungsgemäße Abdeckfolie mit der der Polyesterhaut entsprechenden Seite befestigt, wird die letztere einerseits zwischen die aus bedruckbarem ¥erkstoff bestehende Folie, die als nicht ausdehnungsfähig betrachtet werden kann, und andererseits eine starre Abstützung, die durch das Gefäß gebildet wird, eingeschoben; es ist nun möglich, saubere Schnitte zwischen der entsprechenden Seite der bedruckungsfähigen Folie zu erhalten, wobei die Schlitze bzw. Einschnitte, die durch das Messer erhalten werden, anfangs Einrisse für den Aufbau darstellen. The film, which is made of a material suitable for printing and is positively connected to the polyester skin at all points, also makes it easier to cut out or punch the structure when it is applied to the vessel. In fact, this film is more suitable for grasping when cutting open with a knife than polyester and is better suited than this when cutting through; namely, if you fasten the cover film according to the invention with the side corresponding to the polyester skin, the latter is inserted on the one hand between the film made of printable ¥ Erkstoff, which can be regarded as non-expandable, and on the other hand, a rigid support formed by the vessel; it is now possible to obtain a clean cut between the corresponding side of the bedruckungsfähigen film, wherein the slots or cuts obtained by the blade, initially tears for building illustrate.

Folie 1 vollkommen der Erhöhung der Temperatur, die zur ¥ärmeversiegelung des Bechers 5 vermittels des Firnis 11 notwendig ist. Sie weist den bereits angeführten Vorteil einer großen Widerstandsfähigkeit gegen Durchbrüche auf; eine evtl. Beschädigung der zum Druck geeigneten Folie 9 zieht nicht mehr die unangenehmen Folgen für den Inhalt des Bechers 5 aufgrund der Undurchdringlichkeit des Polyesters und seines Widerstands gegen Feuchtigkeit nach sich..Foil 1 completely the increase in temperature, which mediates for ¥ ärmeversiegelung the cup 5 of the varnish 11 is necessary. It has the already mentioned advantage of great resistance against breakthroughs; any damage to the foil 9 suitable for printing does not pull more the unpleasant consequences for the contents of the cup 5 due to the impermeability of the polyester and its resistance to moisture ..
Schließlich, wie dies bereits weiter oben ausgeführt wurde, zerreißt die Folie 1 nicht mehr beim Öffnen des Bechers 5 durch den Benutzer, der sie nunmehr in einem einzigen Arbeitsgang entfernen kann.Finally, as has already been stated above, the film 1 no longer tears when opening the Cup 5 by the user, who can now remove them in a single operation.
Falls zur Anfertigung der Folie 9 Aluminium verwendet wird, werden diese Ergebnisse bei einer deutlich verringerten Dicke des Aluminiums gegenüber dem gewöhnlich verwendeten erhalten, da sie um mindestens 2o Mm verringert werden kann, beispielsweise um 15 ρ m; die durch das Polyester auf die erfindungsgemäße mehrschichtige Folie aufgeprägten Qualitäten erlauben außerdem, die Folie 9 aus Papier herzustellen, beispielsweise mit einem Gewicht von ^o Gramm pro qm, was im übrigen für das Aluminium den Vorteil des Nichtoxydierens mit sich bringt; selbstverständlich können auch andere zum Druck geeignete Materialien ins Auge gefaßt werden.If 9 Aluminum is used for making the film, these results are obtained usually used at a significantly reduced thickness of the aluminum over the, as it can be reduced by at least 2o mm, for example 15 m ρ; the qualities imprinted on the multilayer film according to the invention by the polyester also allow the film 9 to be produced from paper, for example with a weight of ^ o grams per square meter, which, moreover, has the advantage of non-oxidizing for the aluminum; of course, other materials suitable for printing can also be envisaged.
Die Dicke der Polyesterhaut 1o kann gleichermaßen geringer als 2o Λ*. m sein, und beispielsweise in der Größenordnung von 12 Aim liegen.The thickness of the polyester skin 1o can also be less as 2o Λ *. m, and for example in the Of the order of 12 aim.

Diese Werte, die als Ergebnisse von Versuchen erhalten wurden, sind natürlich lediglich als Beispiel gegeben und variieren in Abhängigkeit von der Abmessung des mittels der erfindungsgemäßen Folie zu verschließenden Gefäßes und in Abhängigkeit von der Art des Inhalts. Sie stimmen im Fall einer weichen, biegsamen erfindungsgemäßen Folie überein, die insbesondere bequem im Gebrauch ist, da es möglich ist, sie in Form von Rollen aufzuwickeln und auf die Gefäße aufzubringen, die kontinuierlich vorbeigeführt werden, in-dem sie nach Bedarf abgerollt wird. These values, which were obtained as the results of tests, are of course only given as an example and vary depending on the dimensions of the vessel to be closed by means of the film according to the invention and depending on the type of content. They are the same in the case of a soft, pliable film according to the invention, which is particularly convenient to use since it is possible to wind it up in the form of rolls and to apply it to the vessels, which are continuously moved past by being unrolled as required.
