Abstract

In the manufacture of blister packs of prescribed form and defined volume in a continuous operation using at least two webs of sheet, which are taken off a roll, of different material such as PVC and aluminium as the deformation and cover sheet, it is possible for a waste product to be produced which is suitable for recycling if the sealing of the cover-sheet web onto the deformation-sheet web carrying the goods to be packaged is limited to the region of the surface of the package to be divided and if, after the packs have been separated, the waste material from the deformation and cover sheet is collected separately for the purpose of recycling. This permits individual disposal and recycling of waste material of different consistency. A tool comprises a pair of tool parts (21, 22) in plate form which carry out the sealing process, of which a lower part (21) has recesses (211) for receiving the blisters (112) of the deformation sheet (11) and an upper, heatable part (22) has a fluted printing surface, the active surface (221) which comes into contact with the cover sheet (12) during sealing being limited to the surface boundaries of the blister package to be divided. <IMAGE>

Die Art der Herstellung von Blister-Verpackungen hat in zunehmendem Maße für Arzneimittel in Tabletten- oder Kapselform Eingang in die Praxis gefunden; so trifft man heute kaum mehr in Röhrchen verpackte Tabletten an. Das Blistern wird aber auch für Gegenstände anderer, teil­ weise recht unterschiedlicher Bereiche verwendet, so z.B. im Haushalts-, Lebensmittel- und Süßwaren-, Geschäfts­und Büro-, Do-it-yourself-Bereich usw. Man findet heute allenthalben geblisterte Tuben, Fläschchen, Werkzeuge, Werkstücke wie Nägel, Heftzwecken, Klammern, Gewürzgefäße etc. Alle diese Angaben sind rein beispielhaft zu sehen, da die Entwicklung eher auf eine Ausweitung der Einsatz­bereiche denn auf eine Beschränkung schließen läßt.The way in which blister packs are manufactured has found increasing use in medicine for tablets or capsules. you can hardly find tablets packed in tubes today. Blistering is also used for other people's items wise used quite different areas, such as in the household, food and confectionery, business and office, do-it-yourself area, etc. Today you will find blistered tubes, vials, tools, workpieces such as nails, tacks, staples, Spice jars etc. All this information is to be seen purely as an example, since the development suggests an expansion of the areas of application rather than a restriction.

Angesichts der zunehmenden Verknappung der Rohstoffe und Energiequellen und der Bestrebungen, gerade Ver­packungsmaterialien wieder zu verwenden, ist es bekannt geworden (DE-OS 31 10 254), die beim Herstellen von Blister-Verpackungen insbesondere in der Pharma-Industrie als Fehlchargen in großen Mengen anfallenden Abfälle dem Recycling zuzuführen. Infolge der Trennungsprobleme der üblichen Aluminium-PVC-Materialkombination bzw. zur Vermeidung dieser Probleme wird diese Materialkombination, also PVC und Aluminium gemeinsam, einer Zerkleinerungs­maschine zugeführt und granuliert, und das erhaltene Alu-­PVC-Granulat wird mit Kunststoffzusätzen, speziell Kunst­stoff-Rohgranulaten, zu neuen Kunststoffprodukten verar­beitet, vor allem in Preß-, Spritzguß- oder Extrudier­verfahren. Das so erhaltene Material, das eine Entsorgung der Abfälle überflüssig macht, soll im Kunststofformenbau für PU-Schäumformen, als Füllmaterial bei Klebstoffen und Vergußmassen in der Bauindustrie und als Zumischprodukt bei der Herstellung von Spanplatten verwendet werden. Es handelt sich damit sämtlich um die Verwendung eines Mischmaterials für Massenteile, bei denen es nicht auf die Qualität des Ausgangsstoffes ankommt, sondern eben Füll- und Zusatzstoffe minderer Qualität ohne für das Endprodukt abträgliche Wirkung einsetzbar sind. Damit wird aber gerade nicht der Hochwertigkeit und dem Preis der Basisstoffe Aluminium und Kunststoff wie PVC Rech­nung getragen. Vielmehr ergeben sich erkennbar Schwierig­ keiten dadurch, daß bei aus unterschiedlichem Material bestehenden Folienbahnen, die im Falle der Verblisterung von Arzneimitteln in der Regel PVC als Material für die Verformfolie und Aluminium als Abdeckfolie aufweisen - obwohl in vielen anderen Bereichen z.B. auch andere Kunststoffe als Verformfolien und Papiermaterialien als Abdeckfolie Verwendung finden - und ganzflächig durch Siegeln oder sonstiges Kleben miteinander verbunden sind, diese Materialien somit gemeinsam d.h. im Verbund anfallen. Das hat dazu geführt, daß bisher die am Ende eines Herstellungsvorganges von Blisterpackungen in Mengen von 10 bis 20% der Verpackungsfolienbahnen anfallenden, miteinander verbundenen Abfallstreifen bzw. Stanzgitter nicht dem Recycling zugeführt, sondern im Gegensatz zu dem bekannten Recycling bei FehlchargenAbfällen in der Pharmaindustrie nach wie vor als nicht verwendbarer Abfall betrachtet werden und deshalb entsorgt werden müssen.In view of the increasing scarcity of raw materials and energy sources and the efforts to reuse packaging materials in particular, it has become known (DE-OS 31 10 254) that large batches of defective batches occur in the manufacture of blister packs, particularly in the pharmaceutical industry Recycle waste. As a result of the separation problems of the usual aluminum-PVC material combination or in order to avoid these problems, this material combination, i.e. PVC and aluminum together, is fed to a comminution machine and granulated, and the aluminum PVC granulate obtained is mixed with plastic additives, especially plastic raw granules processed new plastic products, especially in pressing, injection molding or extrusion processes. The material obtained in this way, which makes waste disposal superfluous, is to be used in plastic mold construction for PU foam molds, as filler material for adhesives and casting compounds in the construction industry and as an admixture product in the production of chipboard. It is therefore all about the use of a mixed material for mass parts, where the quality of the raw material is not important, but fillers and additives of lower quality can be used without detrimental effects on the end product. However, this does not take into account the high quality and the price of the basic materials aluminum and plastic such as PVC. Rather, there are recognizably difficult due to the fact that in the case of film webs made of different materials, which in the case of blistering of medicinal products generally have PVC as the material for the deforming film and aluminum as the covering film - although in many other areas, for example, plastics other than deforming films and paper materials are also used as the covering film - and are connected to one another over the entire area by sealing or other adhesive, these materials thus occur together, that is to say in a bond. This has led to the fact that the interconnected waste strips or lead frames at the end of a manufacturing process of blister packs in quantities of 10 to 20% of the packaging film webs have not been recycled, but, in contrast to the known recycling of batch waste in the pharmaceutical industry, as before be regarded as unusable waste and therefore have to be disposed of.

Der Erfindung liegt deshalb die Aufgabe zugrunde, den Verblisterungsvorgang so zu gestalten, daß ein Recycling­gerechtes Abfallerzeugnis anfällt, das die Wiedergewinnung der teueren Rohstoffe jeweils für sich und damit beträcht­liche Kostenersparnisse an Material ermöglicht, sowie ein zu diesem Zwecke geeignete Vorrichtung vorzusehen.The invention is therefore based on the object to design the blistering process so that a recyclable waste product is obtained, which enables the recovery of the expensive raw materials and thus considerable cost savings in material, and to provide a device suitable for this purpose.

Diese Aufgabe wird bei dem Verfahren nach der Erfindung dadurch gelöst, daß das Siegeln auf den Bereich der Fläche der abzuteilenden Verpackung begrenzt und das Abfallmaterial von Verform- und Deckfolie nach dem Abteilen der Verpackungen separat zum Zwecke des Recy­clings gesammelt wird, und bei dem eingangs beschriebenen Werkzeug dadurch, daß die Begrenzung wenigstens einer der mit einer der Packungsfolien beim Siegeln in Berüh­rung gelangenden Wirkflächen der beiden Werkzeugteile den Flächengrenzen der Blister-Verpackung entspricht.This object is achieved in the method according to the invention in that the sealing is limited to the area of the area of the packaging to be divided and the waste material from the shaping and cover film is collected separately for the purpose of recycling after the packaging has been divided, and in the case described at the beginning Tool in that the delimitation of at least one of the active surfaces of the two tool parts coming into contact with one of the packaging foils during sealing corresponds to the surface boundaries of the blister packaging.

Mit erfindungsgemäßem Verfahren und Werkzeug wird somit in Lösung der Aufgabe eine Möglichkeit geschaffen, unmittelbar im Zuge des Blister-Verpackens ein nur unter geringem technischen Aufwand erzielbares Abfallprodukt anfallen zu lassen, das direkt dem Recycling jeder einzelnen Produktkomponente für sich zugeführt werden kann. Dieses Verpackungsverfahren ist damit wesentlich umwelt­freundlicher und Energie sparender, wenn man bedenkt, daß die Verschnitte der Folienbahnen bei der Herstellung solcher Blisterpackungen zwischen 10 und 20 % betragen und ohne jeglichen nachfolgenden Trennvorgang einem Recycling zugeführt werden können. Bei der erwähnten zunehmenden Neigung zum Verpacken mittels Blistern stellt dies einen wesentlichen Schritt zur Ersparnis von immer knapper werdenden Rohstoffen dar, wie natürlich auch angesichts der möglichst niedrig zu haltenden Folgekosten für die Weiterverarbeitung von Abfällen eine wirksame Kostenersparnis erzielt werden kann. Der erfindungsge­mäße Aufbau des Werkzeuges macht es in einfacher Weise möglich, nur die Fläche der eigentlichen Verpackung mit der Verformfolie zu verbinden, während alle übrigen Teile der ablaufenden Folien voneinander getrennt blei­ben. Ein solches Werkzeug ist in seinem Gesamtaufbau unaufwendig herstellbar und kann leicht in bestehenden Anlagen nachgerüstet werden, wie auch vorhandene Werk­zeuge beispielsweise durch Fräsen oder Erodieren nachge­arbeitet werden können. Das Stanzwerkzeug in einer Trenn- oder Stanzstation der Anlage ist dabei in der Größe der Verpackung ausgebildet, um exakt entlang der Wirkflächen die Verpackung aus dem laufenden Folien­strang herauszutrennen, so daß die Abfälle, die seitlich und zwischen den einzelnen Verpackungen bestehen, in einem fortlaufenden Abfallstrang abgeführt und jeweils für sich weiterverwertet werden können.With the method and tool according to the invention, a solution to the problem is thus created, in the course of blister packaging, to produce a waste product which can only be obtained with little technical effort and which can be directly recycled for each individual product component. This packaging process is therefore much more environmentally friendly and energy-saving, if one considers that the blanks of the film webs in the production of such blister packs are between 10 and 20% and can be recycled without any subsequent separation process. With the increasing tendency towards blister packaging mentioned above, this represents an important step towards saving increasingly scarce raw materials, just as, of course, effective cost savings can also be achieved in view of the subsequent costs for the further processing of waste that must be kept as low as possible. The structure of the tool according to the invention makes it possible in a simple manner to connect only the surface of the actual packaging to the deforming film, while all other parts of the running films remain separate from one another. The overall structure of such a tool is inexpensive to manufacture and can easily be retrofitted in existing systems, just as existing tools can be reworked, for example by milling or eroding. The punching tool in a separating or punching station of the system is designed in the size of the packaging in order to separate the packaging from the running film strand exactly along the active surfaces, so that the waste that exists on the side and between the individual packages is in a continuous waste strand can be dissipated and recycled for themselves.

Um das Verpackungsgut möglichst schonend zu behandeln, was insbesondere bei wärme- und/oder druckempfindlichen Materialien wie z.B. Weichgelatinekapseln von Bedeutung ist, kann in Weiterbildung des erfindungsgemäßen Ver­fahrens die Abdeckfolie beim Siegeln ausschließlich in Berührungsbereichen mit der tiefgezogenen, das Ver­packungsgut tragenden Verformfolie mit für das Versie­geln erforderlichem Druck und Wärme beaufschlagt werden.In order to treat the packaged goods as gently as possible, What is particularly important for heat- and / or pressure-sensitive materials such as soft gelatin capsules, in a further development of the method according to the invention, the sealing film can be subjected to the pressure and heat required for sealing only in contact areas with the deep-drawn deformation film carrying the packaged goods.

In besonders zweckmäßiger Anordnung des Siegelwerkzeuges kann die Wirkfläche auf die Oberflächenabmessungen der Blister-Verpackung begrenzt sein, wenn es sich bei letzteren um solche mit ebenen Deckfolien handelt. Vorzugsweise kann die Wirkfläche des zweiten, oberen Werkzeugteils gegenüber den übrigen Oberflächenabschnitten desselben erhaben sein. Im Zuge der Nachrüstung kann man dieses leicht bei vorhandenen Werkzeugteilen vorsehen, indem die bei den bisher bekannten Siegelplatten im wesent­lichen der Breite des Folienstranges entsprechende Ober­fläche abgefräst oder erodiert wird, so daß als Wirkfläche nur noch die Oberfläche der zu erzeugenden Verpackung stehen bleibt.In a particularly expedient arrangement of the sealing tool, the effective area can be limited to the surface dimensions of the blister packaging if the latter are those with flat cover foils. The active surface of the second, upper tool part can preferably be raised in relation to the other surface sections thereof. In the course of retrofitting, this can easily be provided in the case of existing tool parts by milling or eroding the surface corresponding to the width of the film strand in the known sealing plates, so that only the surface of the packaging to be produced remains as the active surface.

Um zu vermeiden, daß die beim Siegelvorgang zuzu­führende Wärme und der Druck irgendwelche negativen Einflüsse auf das in den Tiefziehnestern der Verform­folie befindliche Verpackungsgut haben, was insbesondere dann schädlich ist, wenn es sich um empfindliche Pharma­zeutika wie z.B. Weichgelatinekapseln handelt, kann zweckmäßig das obere Werkzeugteil in seiner Wirkfläche mit einer nach Zahl, Größe und Plazierung den Ausnehmungen im unteren Werkzeugteil entsprechenden erwärmungsfreien Stellen ausgebildet sein.In order to avoid that the heat and pressure to be supplied during the sealing process have any negative effects on the packaging material located in the deep-drawing nests of the deformable film, which is particularly harmful when it comes to sensitive pharmaceuticals such as e.g. Soft gelatin capsules are concerned, the upper part of the tool can expediently be formed in its active surface with a heat-free point corresponding to the number, size and placement of the recesses in the lower part of the tool.

Diese Abfallsammelstation 16 ist in ihrer separaten Ausbildung für die beiden Folien im Gegensatz zu dem Stand der Technik, in dem die Abfälle nur gemeinsam gesammelt werden können, durch die besondere Ausbildung des Siegelwerkzeuges gemäß Fig. 2 und 3 möglich. Natürlich brauchen die Abfälle nicht un­bedingt aufgerollt zu werden, sondern sie können auch, selbstverständlich bevorzugt separat, jeweils einem ersten Weiterverarbeitungsvorgang, z.B. einem Häcksel- und/­oder Granulierprozeß, zugeführt werden.A blister packaging system shown in FIG. 1, which is however only shown in principle and shows no details, comprises on a machine bed 10 for the production of blister packs for pharmaceuticals (tablets, capsules or the like) by means of a base film, as a rule designating and used deformation film 11, which runs from a supply roll 111, and a cover film 12, which runs from a supply roll 121, a deformation station 13, in which the deformation film 11 to form nests 112 (FIG. 2) for receiving Tablets 3 is deep-drawn, a sealing station 14, in which the deforming film 11 and cover film 12 are connected to one another with the application of heat and pressure, a separating or punching station 15, in which the finished blister packs are punched out of the continuous film strip, and a waste collecting station 16 , in which separate collecting rollers 161 for the waste of the deforming film 11 and 162 for the waste of the cover film 12 are provided n are. In contrast to the prior art, in which the waste can only be collected together, this waste collection station 16 is in its separate design for the two foils due to the special design of the sealing tool according to FIG. 2 and 3 possible. Of course, the waste does not necessarily have to be rolled up, but it can, of course, preferably also be fed separately, in each case to a first further processing operation, for example a chopping and / or granulating process.

Ein den wesentlichen Bestandteil der Siegelstation 14 bildendes Siegelwerkzeug 2 umfaßt, wie in Fig. 2 dar­gestellt, ein unteres Werkzeugteil 21 in Form einer Gegenhalteplatte und ein oberes Werkzeugteil 22 in Form eines Siegelstempels. Die beiden Werkzeugteile 21, 22 sind in ihrer Ruhestellung, d.h. im Abstand zueinander, abgebildet. Zwischen ihnen läuft das doppelte Folien­band, bestehend aus Verformfolie 11 mit daran bereits vorgeformten Nestern 112 und darin abgelegtem Verpackungs­gut 3, hier in Form von Tabletten, und aus Deckfolie 12, taktweise durch. In der gezeigten Position befinden sich die Nester 112 über in der Gegenhalteplatte 21 ausgeformten Ausnehmungen 211. In dieser Position kann der Siegelvorgang eingeleitet werden, indem die Gegen­halteplatte 21 in Richtung des Pfeiles A aufwärts be­wegt wird, so daß die Nester 112 von den Ausnehmungen 211 aufgenommen werden und die Gegenhalteplatte 21, die nicht erwärmt und, falls notwendig, in geeigneter Weise gekühlt ist, zunächst gegen die Unterseite der Verform­folie 11 zur Anlage kommt. Der Siegelstempel 22, der auf die erforderliche Temperatur erwärmt wird, ist üblicher­weise fest, kann aber bei manchen Vorrichtungen auch in Richtung des Pfeiles B nach unten gefahren werden. Durch diese Relativbewegung drückt die Oberfläche der Verform­folie 11 gegen die Deckfolie 12. Die Unterseite der Deckfolie 12 ist mit einer für die Verbindung erforder­lichen Kleberschicht versehen, die durch den zwischen Gegenhalteplatte 21 und Siegelstempel 22 erzeugten Druck und die von dem Stempel 22 übertragene Wärme die Verbin­dung mit der Oberfläche der Verformfolie 11 herbeiführt.A sealing tool 2 forming the essential component of the sealing station 14 comprises, as shown in FIG. 2, a lower tool part 21 in the form of a counter plate and an upper tool part 22 in the form of a sealing stamp. The two tool parts 21, 22 are shown in their rest position, ie at a distance from one another. The double film strip, consisting of deforming film 11 with nests 112 already preformed thereon and packaged goods 3 deposited therein, here in the form of tablets, and of cover film 12 runs through them in cycles. In the position shown, the nests 112 are located above recesses 211 formed in the counter-holding plate 21. In this position, the sealing process can be initiated by moving the counter-holding plate 21 upwards in the direction of arrow A, so that the nests 112 are received by the recesses 211 are and the counter plate 21, which is not heated and, if necessary, cooled in a suitable manner, first comes to rest against the underside of the deforming film 11. The sealing stamp 22, which is heated to the required temperature, is usually fixed, but can also be moved downward in the direction of the arrow B in some devices. As a result of this relative movement, the surface of the deforming film 11 presses against the cover film 12. The underside of the cover film 12 is provided with an adhesive layer required for the connection, the connection being produced by the pressure generated between the holding plate 21 and the sealing stamp 22 and the heat transmitted by the stamp 22 brings about with the surface of the deforming film 11.

Aus der Unteransicht der Fig. 3 in Verbindung der Seiten­ansicht der Fig. 2 ist erkennbar, daß der Siegelstempel 22 eine erhabene Wirkfläche 221 umfaßt, deren Oberfläche maximal exakt der Oberfläche der herzustellenden Verpackung entspricht oder kleiner als diese ist, so daß auf jeden Fall vermieden wird, daß die wie nachstehend beschriebenen Stanzabfälle/Stanzgitter irgendeinen Verbund zwischen den Materialien aufweisen, sondern daß eine einfache und schnelle separate Abführung gewährleistet ist. Die Verpackung umfaßt, rein beispielhaft, wie gezeigt, drei Tiefziehnester für Tabletten. Die Wirkfläche ist gegenüber dem übrigen Teil der Siegelplatte durch Abfräsen des letzteren erzeugt, aber es kommt für die Herstellung dieser Wirkfläche auch jedes andere geeignete Herstellungsverfahren in Betracht. Das Stanzwerkzeug der Stanzstation 15 wird in entsprechender Weise vorge­sehen sein, so daß Verpackungen entsprechend der Wirk­fläche zum Abtransport aus der Anlage 1 ausgestanzt werden, während ein Abfall-Folienstreifen jeweils der Verformfolie 11 und der Deckfolie 12 entsprechend dem aus Fig. 3 erkennbaren leiterähnlichen Raster abläuft. Mit anderen Worten bildet die Gesamtoberfläche des Siegelstempels 22 einen Rezeß 222 gegenüber der Wirk­fläche 221, die außerdem zur Verbesserung des Siegel­druckes mit einer für sich bekannten Riffelung 223 (diese ist hier nur im linken oberen Teil gezeigt, er­streckt sich aber über die gesamte Wirkfläche) sowie mit erwärmungsfreien Stellen 224 entsprechend den Aus­nehmungen 211 des unteren Werkzeugteils 21 versehen ist. Die Riffelung bildet bei plattenförmiger Ausbildung der Werkzeuge, wie im Beispiel gezeigt, kleine, pyramiden- oder pyramidenstumpfförmige Erhebungen, so daß der Siegeldruck trotz möglicherweise in den Folien bestehender Unebenheiten oder Aufwerfungen gleichmäßig ausgeübt wird und somit eine fehlerfreie Verpackung entsteht. - Werden hingegen Rollen- oder Walzenwerkzeuge verwendet, so ist deren Oberfläche üblicherweise mit einer Anordnung sich kreuzender, erhabener Linien zur Erzielung gleichmäßiger Druckverhältnisse versehen.From the bottom view of FIG. 3 in connection with the side view of FIG. 2 it can be seen that the sealing stamp 22 comprises a raised active surface 221, the surface of which corresponds exactly to the surface of the packaging to be produced or is smaller than this, so that it is avoided in any case becomes that the punching waste / punching grid as described below have any connection between the materials, but that a simple and quick separate discharge is guaranteed. The packaging comprises, by way of example only, three deep-drawn nests for tablets, as shown. The active surface is produced in relation to the remaining part of the sealing plate by milling the latter, but any other suitable manufacturing method can also be used for the production of this active surface. The punching tool of the punching station 15 will be provided in a corresponding manner, so that packaging is punched out according to the active surface for removal from the system 1, while a waste film strip of the deforming film 11 and the cover film 12 runs according to the ladder-like pattern shown in FIG. 3 . In other words, the total surface of the sealing stamp 22 forms a recess 222 with respect to the active surface 221, which also improves the sealing pressure with a corrugation 223 which is known per se (this is only shown here in the upper left part, but extends over the entire active surface) and is provided with heat-free points 224 corresponding to the recesses 211 of the lower tool part 21. The corrugation forms in the case of a plate-shaped design of the tools, as shown in the example, small, pyramid-shaped or truncated pyramids, so that the sealing pressure is exerted evenly, despite any unevenness or throwing-up that may exist in the foils, and this results in faultless packaging. - Will on the other hand, if roller or roller tools are used, their surface is usually provided with an arrangement of intersecting, raised lines in order to achieve uniform pressure conditions.

Mit dem in den Figuren gezeigten plattenförmigen Siegel­werkzeug und entsprechend ausgestalteten Stanzwerkzeugen ist ein kontinuierlich getakteter Herstellungsvorgang möglich. Will man einen ungetakteten, fortlaufenden Arbeitsfluß erzielen, so bietet sich hierfür die vorer­wähnte Ausbildung der Werkzeuge in Walzenform an, wobei dann ebenso wie beim Takten die Werkzeuge genau hinsicht­lich ihrer Relativposition zueinander gesteuert werden müssen.With the plate-shaped sealing tool shown in the figures and correspondingly designed punching tools, a continuously clocked manufacturing process is possible. If you want to achieve an unclocked, continuous workflow, the above-mentioned design of the tools in the form of a roller is suitable for this purpose, and then, just as with clocking, the tools must be controlled precisely with regard to their relative position to one another.

Die insgesamt mit der Erfindung erzielbaren Vorteile bestehen darin, daß voneinander separierte Folienabfälle definierter Konsistenz anfallen, die man einfach und schnell einem allein auf die betreffende einzelne Mate­rialkomponente abgestellten und dafür spezifischen Recyclingvorgang zuführen kann, so daß man ein hochgradig reines und damit hochwertiges Recyclingprodukt erhält. Zugleich ist es möglich, die Kosten für die Erzeugung der Riffelung, die auf die Abmessungen der jeweiligen Verpackungen zu begrenzen ist, zumindest hinsichtlich der Randbereiche zu reduzieren. Letzteres ist, berück­sichtigt man die Vielzahl der unterschiedlichen Ver­packungsgrößen und der damit verbundenen Werkzeugbereit­haltung, für die Gestehungskosten der Anlage mit Werk­zeugen von wesentlicher Bedeutung. Vor allem aber wird es durch die Erfindung völlig überflüssig, die doch beträchtlichen Abfälle aus den Folien, die speziell in der Verpackungsindustrie für pharmazeutische Produkte anfallen, entsorgen zu müssen, so daß die Erfindung einen maßgeblichen Beitrag für eine umweltfreundlichere Gestal­tung der Verpackungstechnik darstellt.The overall advantages that can be achieved with the invention are that there are separated film wastes of a defined consistency, which can be easily and quickly fed to a recycling process that is geared solely to the individual material component in question, so that a highly pure and thus high-quality recycling product is obtained. At the same time, it is possible to reduce the cost of producing the corrugation, which is to be limited to the dimensions of the respective packaging, at least with regard to the edge regions. The latter, taking into account the large number of different packaging sizes and the associated tool availability, is essential for the production costs of the system with tools. Above all, however, the invention completely eliminates the need to dispose of the considerable waste from the films, which are produced especially in the packaging industry for pharmaceutical products, so that the invention makes a significant contribution to a more environmentally friendly design of the packaging technology.

Natürlich ist die Erfindung nicht auf diesen speziellen Zweig der Verpackungstechnik beschränkt, sondern sie kann mit Erfolg auch überall dort eingesetzt werden, wo Folien oder Schichten unterschiedlicher Materialarten verarbeitet werden und zu Verbundabfällen führen, deren separate Entsorgung Schwierigkeiten bereitet. Das trifft beispielsweise für die Milchindustrie zu, speziell das Füllen von Tiefzieh-Plastikbechern mit Milch, Sahne, Joghurt, Quark, Pudding etc. auf solchen Füllanlagen, in denen der Kunststoff für die Becher als fortlaufende Bahn zugeführt, aufgeheizt und mittels Formstempel oder Vakuum in größeren, zusammenhängenden Einheiten tief­gezogen wird, worauf, im Gegensatz zu der häufig ein­gesetzten Einzelbecher-Befüllung, das Befüllen der Ein­heit und das Verschließen mit einer von einer Vorrats­rolle abgezogenen Endlos-Alufolie in einer Siegelstation erfolgt. Dabei ist es bisher so, daß das beim Ausstanzen der Einzelbecher anfallende Stanzgitter gehäckselt und so entsorgt wird. Die Erfindung ermöglicht auch hier eine separate Abführung von Plastikmaterial und Deck- (Alu-)folie zum Zwecke eines rohstoffsparenden Recyclings.Of course, the invention is not limited to this special branch of packaging technology, but can also be used successfully wherever films or layers of different types of material are processed and lead to composite waste, the separate disposal of which is difficult. This applies, for example, to the dairy industry, especially the filling of thermoformed plastic cups with milk, cream, yogurt, curd cheese, pudding etc. on filling systems in which the plastic for the cups is fed as a continuous web, heated up and stamped or vacuumed in larger, coherent units is deep-drawn, whereupon, in contrast to the frequently used single-cup filling, the unit is filled and sealed with a continuous aluminum foil removed from a supply roll in a sealing station. So far, it has been the case that the leadframe resulting from the punching out of the individual cups is chopped and thus disposed of. The invention also enables a separate removal of plastic material and cover (aluminum) foil for the purpose of raw material-saving recycling.
