Technisches GebietTechnical field

Die Erfindung betrifft ein Verfahren zur Herstellung einer Packung mit einem Trägerkörper aus flächigem Material, der innerhalb eines ebenen Bereichs mehrere durch Verformung dieses Materials hergestellte Vertiefungen zur Aufnahme des Packungsgutes insbesondere von Tabletten, Kapseln und dergleichen aufweist und der in diesem ebenen Bereich flächig mit einer Aluminium-Verschlußfolie verbunden ist, wobei als Trägerkörper ein Stück einer Aluminiumfolie mit einer Dicke im Bereich von 0,05 bis 0,30 mm eingesetzt wird, welche an beiden Oberflächenseiten Kunststoffschichten aufweist, wobei der Aluminiumgehalt der Leerpackung mehr als 80 Gew.-% beträgt und wobei die Vertiefungen im Trägerkörper durch Kaltverformungsverfahren unter Anwendung von Matrizen- und Patrizenwerkzeugen ausgebildet und zumindestens an ihrer konkaven Seite mit einer siegelfähigen Kunststoffschicht versehen werden.The invention relates to a method for producing a pack with a support body made of sheet material, which within a flat area several by deforming this material prepared recesses for receiving the packaged goods in particular of tablets, capsules and the like and the flat in this flat area with an aluminum sealing film is connected, with a piece as the carrier body an aluminum foil with a thickness in the range of 0.05 to 0.30 mm is used, which has plastic layers on both surface sides has, the aluminum content of the empty pack is more than 80 wt .-% and wherein the depressions in Support body by cold forming process using Matrices and male tools trained and at least on its concave side with a sealable plastic layer be provided.

Stand der TechnikState of the art

Die eingangs genannten Packungen werden als Durchdrück- oder Blisterpackungen bezeichnet und 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 mm, bei der die Vertiefungen durch ein Heißverformungsverfahren hergestellt sind. Diese Formgebungsverfahren finden in vielen technischen Gebieten Anwendung. The packs mentioned above are called push-through or Designated blister packs and generally consist of one Carrier body made of flat material, which is within a flat Area several produced by deformation of this material Wells for receiving the packaging goods, in particular from Has tablets, capsules and the like. And in this plane Area is connected flat with an aluminum sealing film. In many cases, the carrier body material consists of a Plastic film, e.g. from a PVC film with a thickness in the range from about 0.2 to 0.3 mm, in which the depressions are replaced by a Hot forming processes are made. This molding process are used in many technical fields.

Es wird in diesem Zusammenhang auf die EP-A2-0593 034 auf dem Gebiet der Automobil-Bauteil-Herstellung und auf die US-A-5,249,446 auf dem Gebiet der technischen Bauteil-Herstellung, nämlich der Herstellung von Wärmeaustauschern hingewiesen.In this context, reference is made to EP-A2-0593 034 on the Field of automotive component manufacturing and to US-A-5,249,446 in the field of technical component production, namely the manufacture of heat exchangers pointed out.

Im vorliegenden Fall werden jedoch relativ dünne Materialien eingesetzt und auch verformt, wobei durch Drücken auf die Rückseite der vorgenannten Vertiefung des Trägerkörpers diese verformt und die in ihr enthaltene Tablette oder Kapsel unter Durchstoßung der Verschlußfolie der Packung entnommen oder die Verschlußfolie abgezogen werden kann.In the present case, however, relatively thin materials used and also deformed, by pressing on the Back of the aforementioned recess of the carrier body this deformed and the tablet or capsule contained in it Penetration of the sealing film removed from the pack or the Closure film can be removed.

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 Aluminium-Verbundfolie durch Kaltverformen hergestellt werden. Eine solche Verbundfolie besteht - im Hinblick auf die Packung von außen nach innen gesehen - z.B. aus 0,025 mm OPA (orientiertes Polyamid) 0,045 mm Aluminium und 0,060 mm PVC, wobei die enthaltene Aluminiumfolie die Gasdichtheit gewährleistet, während die mit ihr verbundenen Kunststoffolien dem Trägerkörper eine erhöhte Festigkeit geben und - wie man annimmt - beim Kaltverformungsprozeß das Auftreten von Dehnungsspitzen in der Aluminiumfolie, die zu ihrem Einreißen führen können, verhindern. It is now for some to extend the use-up period Medications required, the packaging as gastight as possible to train. With the usual push-through or Blister packs only possible to a limited extent: gases or water vapor can be due to diffusion through the wall of the Kick body. The extent of this diffusion is true depending on the type of used for the support body Plastic material, but is with a plastic carrier body an absolute gas and vapor barrier cannot be achieved. To the Ensuring gas tightness have been in recent years Carrier body made known from an aluminum composite film can be produced by cold forming. Such Composite film exists - with regard to the packaging from the outside seen inside - e.g. made of 0.025 mm OPA (oriented polyamide) 0.045 mm aluminum and 0.060 mm PVC, the included Aluminum foil ensures the gas tightness while using it connected plastic films the carrier body an increased Giving strength and - as one assumes - in the cold forming process the appearance of elongation peaks in the Prevent aluminum foil that can tear them.

Die Erfahrung hat jedenfalls gezeigt, daß die Kaltverformungsfähigkeit des genannten Verbundmaterials wesentlich höher ist als die einer gleichwertigen normalen Aluminiumfolie. Solche Trägerkörper für Blisterpackungen haben aber den Nachteil, daß sie den derzeitigen Entsorgungsvorschriften, gemäß denen Leerpackungen dieser Art nur dann als Ganzes entsorgt werden dürfen, wenn sie mindestens zu 90 Gew.% aus einem einheitlichen Material bestehen, nicht entsprechen. Bei dem vorstehend gegebenen Beispiel beträgt der Aluminiumanteil z.B. nur ca. 57%. Andererseits aber wurde eine Verwendung von Reinaluminiumfolien als Trägerkörper bei Druchdrück- oder Blisterpackungen bisher praktisch nicht für möglich gehalten.Experience has shown that the Cold deformability of the composite material mentioned essential is higher than that of an equivalent normal aluminum foil. Such carrier bodies for blister packs have the Disadvantage that they comply with the current waste disposal regulations which empty packs of this type can only be disposed of as a whole if they are at least 90% by weight from a uniform Material exist, do not correspond. Given the above For example, the aluminum content is e.g. only about 57%. On the other hand, however, the use of pure aluminum foils So far as a carrier body in push-through or blister packs practically not thought possible.

Ferner ist es aus der WO-A1-94/25364 vorbekannt, Blisterpackungen aus mit Kunststoff beschichteten Aluminiumfolien herzustellen. Dabei werden unter erhöhter Temperatur durch Tiefziehen die entsprechenden Vertiefungen ausgebildet, wobei die Kunststoffschicht eine Art Schmiereffekt bewirkt. Dieses Verfahren ist jedoch Energie-aufwendig, wodurch auch die Aluminiumfolie materialmäßig belastet und demgemäß leicht einreißen kann.Furthermore, it is known from WO-A1-94 / 25364, blister packs made of plastic-coated aluminum foils. Thereby, the deep-drawing is carried out under elevated temperature corresponding recesses formed, the plastic layer causes a kind of smear effect. This procedure is however, energy-consuming, which also causes the aluminum foil material stressed and can therefore tear easily.

Aufgabe der vorliegenden Erfindung ist es daher, das Verfahren der eingangs genannten Art besonders energiesparend bei gleichzeitiger Erfüllung der gültigen Entsorgungsvorschriften zu führen. Erfindungsgemäß ist dieses Verfahren dadurch gekennzeichnet, daß in das Kaltverformungsverfahren unter Anwendung von Matrizen- und Patrizenwerkzeugen mit Kunststoffen beschichtete Aluminiumfolien eingesetzt werden, deren matrizenseitige Beschichichtungsoberfläche aus einer Kunststoffschicht in einer Dicke im Bereich von 0,0005 bis 0,020 mm und deren patrizenseitige Beschichtungsoberfläche aus einer heißsiegelfähigen Kunststoffschicht mit einer Dicke im Bereich 0,001 bis 0,030 mm besteht und daß die matrizenseitige Beschichtungsoberfläche der Aluminiumfolie einen nach British Standard (BS) 2782 gemessenen statischen und dynamischen Reibungskoeffizienten von höchstens 0,35 und/oder daß die patrizenseitige Beschichtungsoberfläche der Aluminiumfolie einen solchen von höchstens 0,45 haben (hat).The object of the present invention is therefore the method of type mentioned above particularly energy-saving with simultaneous Compliance with the applicable disposal regulations. According to the invention, this method is characterized in that into the cold forming process using die and Male tools with aluminum foils coated with plastics are used, their coating surface on the die side from a plastic layer in a thickness in the range from 0.0005 to 0.020 mm and their coating surface on the male side from a heat sealable plastic layer a thickness in the range 0.001 to 0.030 mm and that a coating surface of the aluminum foil on the die side static and measured according to British Standard (BS) 2782 dynamic coefficient of friction of at most 0.35 and / or that the coating surface of the aluminum foil on the male side have a maximum of 0.45.

Die vorteilhafte Ausgestaltung des erfindungsgemäßen Verfahrens sind in den Unteransprüchen 2 bis 7 wiedergegeben. The advantageous embodiment of the method according to the invention are given in the subclaims 2 to 7.

    • 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 Auftragsmenge der Schutzlackschicht beträgt beispielsweise 2g/m2.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, for example, a protective lacquer layer (not shown) on the female side. The amount of protective lacquer applied is, for example, 2 g / m 2 .

    Für die Herstellung des in den Figuren dargestellten Trägerkörpers 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 vorliegenden Fall etwa 35%. Eine solche Oberflächenvergrößerung wäre bei einem unbeschichteten Aluminiumband dieser Stärke in reproduzierbarer Weise nicht erreichbar. For the production of the carrier body shown in the figures e.g. from an aluminum strip with a thickness of 0.1 mm assumed that at a. Side of a heat seal lacquer Has a thickness of 0.009 mm. Be on this coated tape now according to the grid of the packs 3 produced by cold working, which is a depth of 4.5 mm exhibit. The cold deformation in the well area in the Material enlargement achieved in the present is Case about 35%. Such an increase in surface area would be an uncoated aluminum tape of this strength in reproducible Way unreachable.

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 Trägerkörpermaterials 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.The cups 3 with the packaged goods, e.g. Tablets 4, filled and with an aluminum sealing film 5 a thickness of 0.01 - 0.04 mm (according to this example from 0.02 mm), which has a heat seal layer on its underside, preferably in the form of a heat seal lacquer coating 6, the a thickness of 0.003 - 0.020 mm (according to this example from 0.009 mm), on the undeformed areas of the carrier body material 7, as indicated by the arrows 8 in FIG. 3, connected by heat sealing. Then the generated band-shaped composite already contained in the packaged goods to the Lines 9 perforated punctiform and the packs finally cut along its contour 10 by punching.

    In Fig. 1, in der die fertige Packung mit an einem Näpfchen 3 aufgebrochener Aluminium-Verschlußfolie 5 dargestellt ist, erkennt man den Bereich der Siegelung 11 (punktiert). An den Perforationen 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 with a well 3rd broken aluminum sealing film 5 is shown recognizes the area of the seal 11 (dotted). On the perforations along the lines 9, the pack can be in any Way. The aluminum content of the empty pack (Carrier body plus sealing film) is in this example 94% by weight.
