Description

Die Erfindung bezieht sich auf ein mehrschichtiges Kunststoffmaterial, insbesondere zur Herstellung von Behältern od. dgl. durch Tiefziehen, aus einer Grundschicht aus fabrikneuem Kunststoff, einer dickeren Kunststoff-Zwischenschicht und einer bedruckten Kunststoff-Außenschicht.The invention relates to a multilayer plastic material, in particular for the production of Containers or the like by deep drawing, from a base layer made of brand new plastic, a thicker one Plastic intermediate layer and a printed plastic outer layer.

Es ist bekannt, verschiedene Behälterarten, z. B. durch Tiefziehen, aus plattenförmigen! Kunststoffmaterial herzustellen. Obwohl man sich bisher mit ungefärbtem oder als Ganzes in einer bestimmten Farbe gefärbten Kunststoffmaterial begnügte, ist in der letzten Zeit in Zusammenhang mit der Darstellung des Produkts ein piattenförmiges, mit einem bestimmten Farbenmuster bedrucktes Ausgangsmaterial stark gefragt. Es ist jedoch technisch nicht möglich, piattenförmiges Material, dessen Dicke einen bestimmten Wert, z. B. 0,3 bis 0,4 mm, überschreitet, zu bedrucken. Aus diesem Grunde ist man denn auch dazu übergegangen, das Ausgangsmaterial, aus dem durch Tiefziehen die Behälter hergestellt werden sollen, aus einer Schicht herzustellen, die annähernd die für die Festigkeit gewünschte Stärke aufweist, auf welcher Schicht ein» dünne, bedruckte Folie befestigt wird.It is known to use various types of containers, e.g. B. by deep drawing, from plate-shaped! Plastic material to manufacture. Although one has so far dyed oneself with uncoloured or as a whole in a certain color Plastic material, has recently been associated with the appearance of the product There is a strong demand for pie-shaped base material printed with a specific color pattern. It is but technically not possible to use a plate-shaped material, the thickness of which has a certain value, e.g. B. 0.3 to 0.4 mm, to be printed. For this reason one has also gone over to that Starting material from which the containers are to be made by deep drawing, from one layer to produce approximately the strength required for strength, on which layer a » thin, printed film is attached.

Nun ist die Abfallmaterialmenge, die bei der Herstellung von Behältern, insbesondere runden Behältern, durch Tiefziehen entstehen, verhältnismäßig groß. Teilweise sind die Abfälle auf 40% des Ausgangsmaterials zu veranschlagen. Wenn man von ganz einfarbigem oder ungefärbtem Ausgangsmaterial ausgeht, bereitet dies keine Schwierigkeiten, da die Abfälle gemahlen und aufs neue zur durch Extrudieren vorgenommenen Herstellung von plattenförmigen! Ausgangsmaterial verwendet werden können. Wenn man jedoch zum Tiefziehen einen mit einer bedruckten Folie kaschierten Werkstoff verwendet, können diese Abfälle nicht aufs neue benutzt werden. Wenn die Abfälle gemahlen und, aufs neue verwendet werden, entsteht nämlich durch das Vorhandensein der beim Bedanken verwendeten Farbstoffe ein nicht gleich und gleichmäßig gefärbtes Produkt, das nicht aufs neue verwende» werden kann. Demzufolge sind die Herstellungskosten bedruckter Behälter beträchtlich höher als die von Behältern, die nichi bedruckt sind.Now the amount of waste material used in the manufacture of containers, especially round containers, arise through deep drawing, relatively large. Some of the waste is 40% of the raw material to rate. If you start from completely monochrome or undyed raw material, prepare this is not a problem, since the waste is ground and re-extruded Manufacture of plate-shaped! Starting material can be used. However, if you go to the If deep-drawing a material laminated with a printed film is used, this waste cannot be removed new ones are used. When the waste is ground up and used again, the The presence of the dyes used when giving thanks is one that is not uniformly and uniformly colored Product that cannot be used again. As a result, the manufacturing cost is more imprinted Containers considerably higher than those of containers that are not printed on.

Der Erfindung liegt die Aufgabe zugrunde, eine wirtschaftliche und billige Herstellung bedruckter Behälter zu ermöglichen, indem man ein plattenförmiges Kunststoffmaterial der eingangs genannten Gattung schafft, dessen Abfall für das Ausgangsmaterial wieder verwendet werden kann.The invention is based on the object of an economical and cheap production of printed To enable container by using a plate-shaped plastic material of the type mentioned creates whose waste can be reused for the starting material.

Die Lösung der Aufgabe besteht gemäß der Erfindung darin, daß bei dem beschriebenen Kunststoffmaterial die Zwischenschicht und die Außenschicht untet Verwendung von bei der Verarbeitung des mehrschichtigen Kunststoffmaterials entstehenden Abfalls gebildet sind.The solution to the problem is according to the invention that in the plastic material described the intermediate layer and the outer layer are used in the processing of the multilayer plastic material resulting waste are formed.

Die aus Abfällen hergestellten Schichten befinden sich zwischen dem Aufdruck und der aus Ausgangsmaterial gebildeten Grundschicht und sind somit praktisch nicht sichtbar. Die Tatsache, daß die Schichten unregelmäßig gefärbt sind, kann sich also nicht störend auswirken. Der unterschiedlich farbige Kunststoffabfall kann somit wieder verwendet werden, was eine Kostenersparnis bedeutet.The layers made from waste are located between the print and that of the raw material formed base layer and are therefore practically invisible. The fact that the layers are irregularly colored, so can not be distracting impact. The differently colored plastic waste can thus be reused, which is a Means cost saving.

Die Herstellung eines solchen mehrschichtigen Kunststoffmaterials kann derart erfolgen, daß man die Grundschicht und die Zwischenschicht durch gleichzeitige Extrusion miteinander verbindet, worauf die bedruckte Schicht durch Laminieren auf die Zwischenschicht aufgebracht wird und das Tiefziehen gegebenenfalls erfolgen kann.The production of such a multilayer plastic material can be carried out in such a way that the The base layer and the intermediate layer are connected to one another by simultaneous extrusion, whereupon the printed layer is applied to the intermediate layer by lamination and the deep drawing, if necessary can be done.

Die Erfindung wird an Hand der Zeichnung erläutert. In der Zeichnung ist der Aufbau eines beispielsweise der Herstellung eines Behälters dienenden Ausgangsmateriais dargestellt.The invention is explained with reference to the drawing. In the drawing, the structure of an example is the Production of a container serving starting material shown.

In der Zeichnung ist ein Querschnitt durch eine Materialschichl dargestellt, die unter anderem eine erste Schicht 1 mit einer Stärke von z. B. 0,5 mm aufweist, die durch Extrusion hergestellt wurde und aus ungebrauchtem, fabrikneuem Kunststoffausgangsmaterial, z. B. Polystyrol, besteht. Diese Schicht ist an eine zweite, gleichfalls aus Polystyrol bestehende und durch Extrusion gebildete Schicht 2 (z. B. mit einer Dicke von 0,4 mm) geheftet, wobei jedoch das Ausgangsmaterial ein Werkstoff ist, der nicht ausschließlich und nur zur Herstellung von Gegenständen verwendet werden könnte. Die Schichten 1 und 2 sind mittels einer an sich bekannten gleichzeitig vor sich gehenden Extrusion verbunden.In the drawing, a cross section through a material layer is shown, including a first Layer 1 with a thickness of e.g. B. 0.5 mm, which was produced by extrusion and made of unused, brand new plastic raw material, e.g. B. polystyrene. This shift is to a second, Layer 2 also consisting of polystyrene and formed by extrusion (e.g. with a thickness of 0.4 mm), but the starting material is a material that is not used exclusively and only for Manufacture of items could be used. Layers 1 and 2 are by means of a per se known at the same time going on extrusion connected.

Auf der Schicht 2 befindet sich eine Folie 3 (z. B. mit einer Dicke von 0,2 mm) aus Polystyrol, deren von der Schicht 2 abgekehrte Außenoberfläche bedruckt ist. Diese Schicht 3 ist in an sich bekannter Weise durch Laminieren auf der Schicht 2 befestigt.On the layer 2 there is a film 3 (z. B. With a thickness of 0.2 mm) made of polystyrene, whose from the Layer 2 facing away from the outer surface is printed. This layer 3 is through in a manner known per se Laminating attached to layer 2.
