Description

Beschichtete Aluminiumfolie mit verbessertem Kaltverformunosver- halten sowie Packung hergestellt unter Verwendung dieser Aluminiumfolie.Coated aluminum foil with improved cold deformation behavior and packaging made using this aluminum foil.
Technisches GebietTechnical field
Die Erfindung betrifft eine beschichtete Aluminiumfolie mit verbessertem Kaltverformungsverhalten sowie eine Packung, insbesondere eine Durchdrück- oder Blisterpackung, hergestellt unter Verwendung einer solchen Aluminiumfolie.The invention relates to a coated aluminum foil with improved cold deformation behavior and to a pack, in particular a push-through or blister pack, produced using such an aluminum foil.
Stand der TechnikState of the art
Durchdrück- oder Blisterpackungen bestehen im allgemeinen aus einem Trägerkörper aus flächigem Material, der innerhalb eines ebenen Bereichs mehrere durch Verformung dieses Materials hergestellte Vertiefungen zur Aufnahme des Verpackungsgutes insbesondere von Tabletten, Kapseln und dgl. aufweist und der in diesem ebenen Bereich flächig mit einer Aluminium-Verschlußfolie verbunden ist. Das Trägerkörpermaterial besteht dabei in vielen Fällen aus einer Kunststoffolie, z.B. aus einer PVC-Folie einer Dicke im Bereich von etwa 0,2 bis 0,3 m, bei der die Vertiefungen durch ein Heißverformungsverfahren hergestellt sind. Durch Drücken auf die Rückseite einer Vertiefung des Trägerkörpers wird diese verformt und die in ihr enthaltene Tablette oder Kapsel unter Durchstoßung der Verschlußfolie der Packung entnommen oder die Verschlußfolie wird abgezogen.Blister packs or blister packs generally consist of a carrier body made of flat material, which has a plurality of depressions made by deforming this material for receiving the packaged goods, in particular tablets, capsules and the like, within a flat area, and which is flat in this flat area with an aluminum Closure film is connected. The carrier body material in many cases consists of a plastic film, e.g. from a PVC film with a thickness in the range of approximately 0.2 to 0.3 m, in which the depressions are produced by a hot-forming process. By pressing on the back of a recess of the carrier body, the latter is deformed and the tablet or capsule contained therein is removed from the pack while piercing the sealing film, or the sealing film is pulled off.
Zur Verlängerung der Aufbrauchfrist ist es nun für manche Medikamente erforderlich, die Packung möglichst gasdicht auszubilden. Dies ist bei den üblichen Durchdrück- bzw. Blisterpackungen aber nur im beschränkten Umfang möglich: Gase bzw. Wasserdampf können infolge Diffusion durch die Wandung des Trägerkörpers treten. Das Ausmaß dieser Diffusion ist zwar abhängig von der Art des für den Trägerkörper verwendeten Kunststoffmaterials, doch ist mit einem Kunststoffträgerkörper eine absolute Gas- und Dampfsperre nicht zu erzielen. Um die Gasdichtheit zu gewährleisten, sind in den letzten Jahren Trägerkörper bekannt geworden, die aus einer Aluminiu Verbundfolie durch Kaltverformen hergestellt werden. Eine solc Verbundfolie besteht - im Hinblick auf die Packung von .auß nach innen gesehen - z.B. aus 0,025 mm OPA (orientiert Polyamid) 0,045 mm Aluminium und 0,060 mm PVC, wobei die entha tene Aluminiumfolie die Gasdichtheit gewährleistet, während d mit ihr verbundenen Kunststoffolien dem Trägerkörper ei erhöhte Festigkeit geben und - wie man annimmt - beim Kaltve formungsprozeß das Auftreten von Dehnungsspitzen in d Aluminiumfolie, die zu ihrem Einreißen führen können, verhi dern. Die Erfahrung hat jedenfalls gezeigt, daß d Kaltverformungsfähigkeit des genannten Verbundmaterials wesen lieh höher ist als die einer gleichwertigen normalen Aluminiu folie. Solche Trägerkörper für Blisterpackungen haben aber d Nachteil, daß sie den derzeitigen Entsorgungsvorschriften, gem denen Leerpackungen dieser Art nur dann als Ganzes entsor werden dürfen, wenn sie mindestens zu 90 Gew.% aus ein einheitlichen Material bestehen, nicht entsprechen. Bei d vorstehend gegebenen Beispiel beträgt der Aluminiumanteil z. nur ca. 57%. Andererseits aber wurde eine Verwendung v Reinaluminiumfolien als Trägerkörper bei Druchdrück- od Blisterpackungen bisher praktisch nicht für möglich gehalten.To extend the use-up period, it is now necessary for some drugs to make the pack as gas-tight as possible. However, this is only possible to a limited extent with the usual push-through or blister packs: gases or water vapor can pass through the wall of the carrier body as a result of diffusion. The extent of this diffusion depends on the type of plastic material used for the carrier body, but an absolute gas and vapor barrier cannot be achieved with a plastic carrier body. To ensure gas tightness, in recent years Carrier bodies have become known which are produced from an aluminum composite film by cold forming. With regard to the packing from the outside inwards, such a composite film consists, for example, of 0.025 mm OPA (oriented polyamide) 0.045 mm aluminum and 0.060 mm PVC Giving support body ei increased strength and - it is assumed - prevent the occurrence of expansion peaks in the aluminum foil in the cold forming process, which can lead to their tearing. In any case, experience has shown that the cold-forming ability of the composite material mentioned is higher than that of an equivalent normal aluminum foil. However, such carrier bodies for blister packs have the disadvantage that they do not comply with the current disposal regulations, according to which empty packs of this type may only be disposed of as a whole if they consist of at least 90% by weight of a uniform material. In the example given above, the aluminum content is z. only about 57%. On the other hand, however, the use of pure aluminum foils as carrier bodies in the case of push-through or blister packs has hitherto not been considered practically possible.
Der Erfindung liegt zunächst die Aufgabe zugrunde, Aluminiu folien mit einer relativ dünnen Beschichtung anzugeben, die ei verbesserte Kaltverformbarkeit aufweisen und die insbesonde als Material hoher Gasdichtheit für Trägerkörper in Bliste Packungen geeignet sind.The invention is based on the object of specifying aluminum foils with a relatively thin coating which have improved cold deformability and which are particularly suitable as a material with high gas tightness for carrier bodies in blister packs.
Darstellung der ErfindungPresentation of the invention
Diese Aufgabe wird anhand der erfindungsgemäß beschichtet Aluminiumfolie dadurch gelöst, daß die Aluminiumfolie eine Dic im Bereich von 0,05 bis 0,3 mm aufweist und daß d matrizenseitige Beschichtungsoberfläche einen nach Briti Standard (BS) 2782 gemessenen Reibungskoeffizienten im Berei von höchstens 0,35, vorteilhaft aber von höchstens 0,3 und/oder daß die patrizenseitige Beschichtungsoberfläche der Aluminiumfolie einen solchen von höchstens 0,45, vorteilhaft aber von höchstens 0,40, haben (hat).This object is achieved on the basis of the aluminum foil coated according to the invention in that the aluminum foil has a thickness in the range from 0.05 to 0.3 mm and in that the coating surface on the die side has a coefficient of friction in the range of at most 0.35 measured according to Briti Standard (BS) 2782 , but advantageously of at most 0.3 and / or that the coating surface on the male side of the Aluminum foil have (has) a maximum of 0.45, but advantageously a maximum of 0.40.

Gemäß einer vorteilhaften Ausgestaltung der Erfindung ist die patrizenseitige Kunststoffschicht heißsiegelfähig und weist eine Dicke im Bereich von 0,001 bis 0,030 mm auf. Gemäß einer weiteren vorteilhaften Ausgestaltung liegt diese Dicke im Bereich von 0,003 bis 0,020 mm, vorteilhaft jedoch im Bereich von 0,003 bis 0,012 mm.According to an advantageous embodiment of the invention, the plastic layer on the male side is heat-sealable and has a thickness in the range from 0.001 to 0.030 mm. According to a further advantageous embodiment, this thickness is in the range from 0.003 to 0.020 mm, but advantageously in the range from 0.003 to 0.012 mm.

Description of the drawings and a way to carry out the
Erfindunginvention
Die Erfindung wird nachstehend anhand der Figuren, die eine vor¬ teilhafte Ausführung der erfindungsgemäßen Packung illustrieren, näher erläutert.The invention is explained in more detail below with reference to the figures, which illustrate an advantageous embodiment of the pack according to the invention.
Fig. 1 zeigt die Packung in der Aufsicht.Fig. 1 shows the pack in supervision.
Fig. 2 zeigt eine schematische Schnittdarstellung gemäß den Linien II-II in Fig. 1;Fig. 2 shows a schematic sectional view along lines II-II in Fig. 1;

Der Trägerkörper 1 wird aus einem kaltverformbaren Aluminiumband mit einer Dicke im Bereich von 0,05 bis 0,3 mm und einer Qualität gemäß Aluminium Association (AA) 8079 oder 8008 hergestellt. Dieses Aluminiumband ist patrizenseitig mit einer siegelfähigen Kunststoffschicht 2, insbesondere in Form eines Heißsiegellackes, einer Stärke von 0,001 - 0,030, vorzugsweise von 0,003 - 0,012 mm, versehen und weist matrizenseitig z.B. eine Schutzlackschicht (nicht dargestellt) auf. Die Auftrags¬ menge der Schutzlackschicht beträgt beispielsweise 2g/m .The carrier body 1 is produced from a cold-formable aluminum strip with a thickness in the range from 0.05 to 0.3 mm and a quality according to the Aluminum Association (AA) 8079 or 8008. This aluminum strip is provided on the male side with a sealable plastic layer 2, in particular in the form of a heat seal lacquer, with a thickness of 0.001-0.030, preferably 0.003-0.012 mm, and has e.g. a protective lacquer layer (not shown). The application amount of the protective lacquer layer is, for example, 2 g / m.
Für die Herstellung des in den Figuren dargestellten Träger¬ körpers wird z.B. von einem Aluminiumband einer Stärke von 0,1 mm ausgegangen, das an einer. Seite einen Heißsiegellack einer Dicke von 0.009 mm aufweist. An diesem beschichteten Band werden nun gemäß dem Raster der herstellenden Packungen Näpfchen 3 durch Kaltverformen hergestellt, die eine Tiefe von 4,5 mm aufweisen. Die durch das Kaltverformen im Näpfchenbereich im Material erreichte Oberflächenvergrößerung beträgt im vorliegen¬ den Fall etwa 35%. Eine solche Oberflächenvergrößerung wäre bei einem unbeschichteten Aluminiumband dieser Stärke in reprodu¬ zierbarer Weise nicht erreichbar. An dem Band werden dann die Näpfchen 3 mit dem Packungsgut, z.B. Tabletten 4, gefüllt und mit einer Aluminium-Verschlußfolie 5 einer Stärke von 0,01 - 0,04 mm (gemäß diesem Beispiel von 0,02 mm), die an ihrer Unterseite eine Heißsiegelschicht, vorzugsweise in Form einer Heißsiegellackbeschichtung 6, die eine Stärke von 0,003 - 0,020 mm (gemäß diesem Beispiel von 0,009 mm) aufweist, an den unverformten Bereichen des Träger- körpermaterials 7, wie in Fig. 3 durch die Pfeile 8 angedeutet, durch Heißsiegelung verbunden. Danach wird der so erzeugte, bereits das Packungsgut enthaltene bandförmige Verbund an den Linien 9 punktförmig perforiert und die Packungen schließlich längs ihrer Kontur 10 durch Stanzen abgetrennt.For the manufacture of the carrier body shown in the figures, for example, an aluminum strip with a thickness of 0.1 mm is assumed, which is attached to a. Side has a heat seal lacquer with a thickness of 0.009 mm. On this coated strip, cups 3 are now produced by cold forming, which have a depth of 4.5 mm, in accordance with the grid of the packs produced. In the present case, the surface enlargement achieved in the material by cold forming in the well area is approximately 35%. Such an increase in surface area would not be achievable in a reproducible manner with an uncoated aluminum strip of this thickness. The cups 3 are then filled on the belt with the packaged goods, for example tablets 4, and with an aluminum sealing film 5 with a thickness of 0.01-0.04 mm (in this example, 0.02 mm), which is on the underside a heat seal layer, preferably in the form of a heat seal lacquer coating 6, which has a thickness of 0.003-0.020 mm (in this example, 0.009 mm), on the undeformed regions of the carrier body material 7, as indicated by the arrows 8 in FIG. 3 Heat seal connected. Thereafter, the tape-like composite thus produced, which already contains the packaged goods, is perforated in a punctiform manner at the lines 9 and the packs are finally separated along their contour 10 by punching.
In Fig. 1, in der die fertige Packung mit an einem Näpfchen 3 aufgebrochener Aluminium-Verschlußfolie 5 dargestellt ist, er¬ kennt man den Bereich der Siegelung 11 (punktiert) . An den Per¬ forationen längs den Linien 9 kann die Packung in beliebiger Weise unterteilt werden. Der Aluminiumanteil der Leerpackung (Trägerkörper plus Verschlußfolie) beträgt bei diesem Beispiel 94 Gew.%.In FIG. 1, in which the finished package is shown with an aluminum sealing film 5 broken open on a well 3, the area of the seal 11 can be seen (dotted). The pack can be subdivided in any way at the perforations along the lines 9. The aluminum content of the empty pack (carrier body plus sealing film) is 94% by weight in this example.
