Dieser bekannte Arzneimittelbehälter stellt eine Arzneimittelverpackung, die der Fachwelt auch als Blisterpackung bekannt ist dar.This known medicament container represents a medicament packaging which is also known to the experts as a blister pack.

In der Deckelfolie dieses bekannten Arzneimittelbehälters sind die Impulsleitungen angebracht. Arzneimittelverpackung dieser Art, d.h. Blisterpackungen ganz allgemein, werden auf Verpackungsmaschinen kontinuierlich in grosser Zahl erzeugt. Dabei wird in der Regel eine Kunststoffmonofolie oder Kunststoffverbundfolie durch Tiefen mit Vertiefungen oder Näpfchen versehen. Der Füllstoff, wie die Dragees oder auch Tabletten, Kapseln, Ampullen und dergleichen werden in die Vertiefungen eingefüllt und anschliessend wird die Deckelfolie aufgesiegelt. Die Blisterpackungen werden in der Regel kontinuierlich aus bandförmigen Folien erzeugt und erst nach dem Einfüllen des Inhaltes und Bedeckeln, auf Konfektionsgrösse zugeschnitten und gegebenenfalls in eine Umverpackung abgefüllt.The impulse lines are attached in the cover film of this known pharmaceutical container. Pharmaceutical packaging of this type, i.e. Blister packs in general are continuously produced in large numbers on packaging machines. As a rule, a plastic monofoil or plastic composite film is provided with recesses or cells by means of depths. The filler, such as the coated tablets or tablets, capsules, ampoules and the like, are filled into the depressions and the cover film is then sealed. The blister packs are generally produced continuously from tape-like foils and only cut to size after filling in the contents and covering, and if necessary, filled into an outer packaging.

Aufgabe vorliegender Erfindung ist es, eine Deckelfolie mit verbesserten Leiterbahnen vorzuschlagen. Die Leiterbahnen sollen in industriellen Fertigungsverfahren auf einfache Weise auf die Deckelfolien aufgebracht werden können und danach eine zuverlässige Stromführung gewährleisten.The object of the present invention is to propose a cover film with improved conductor tracks. The conductor tracks should be able to be applied to the cover foils in a simple manner in industrial production processes and then ensure reliable current guidance.

Erfindungsgemäss wird dies dadurch erreicht, dass die Leiterbahnen eine SnO2/Sb2O3-Hydroxid-Mischung auf einem Mica-Substrat enthalten.This is achieved according to the invention in that the conductor tracks contain a SnO 2 / Sb 2 O 3 hydroxide mixture on a mica substrate.

In einer vorzugsweisen Ausführungsform enthält die Leiterbahnen eine SnO2/Sb2O3-Hydroxid-Mischung auf einem Mica-Substrat und die Deckelfolie besteht aus wenigstens zwei Lagen, wobei die eine Lage das auf dem Arzneimittelverpackung festgelegte Deckelmaterial ist und die zweite Lage eine die Leiterbahnen enthaltende Etikette ist.In a preferred embodiment, the conductor tracks contain a SnO 2 / Sb 2 O 3 hydroxide mixture on a mica substrate and the cover film consists of at least two Layers, the one layer being the lid material fixed on the pharmaceutical packaging and the second layer being a label containing the conductor tracks.

Die erfindungsgemässe Deckelfolie kann beispielsweise ein Trägermaterial und, auf dem Trägermaterial aufgebracht, die Leiterbahnen aufweisen. Damit die Leiterbahnen vor mechanischen Beschädigungen geschützt sind, kann ein wenigstens ein weiteres Material auf dem Trägermaterial und über den Leiterbahnen liegend, aufgebracht sein.The cover film according to the invention can, for example, have a carrier material and, applied to the carrier material, the conductor tracks. In order that the conductor tracks are protected from mechanical damage, at least one additional material can be applied to the carrier material and lying over the conductor tracks.

Als Trägermaterial der Deckelfolie kann eine Tragertotie, beispielsweise eine Kunststoff-Folie hoher Sprödigkeit, wie z.B. eine Polyolefinfolie, eine Polyethylenfolie oder eine Polyvinylchloridfolie, Anwendung finden. Die Sprödigkeit kann beispielsweise durch die Zugabe von Füllstoffen, wie z.B. Talk, Glimmer usw., erreicht werden. Andere Kunststoff-Folien können Acrylnitril-Styrol-haltige Folien sein.A carrier film, for example a plastic film of high brittleness, such as e.g. a polyolefin film, a polyethylene film or a polyvinyl chloride film can be used. The brittleness can be increased, for example, by the addition of fillers, e.g. Talk, mica, etc. can be achieved. Other plastic films can be acrylonitrile-styrene-containing films.

Als Trägermaterialien können beispielsweise auch Papiere oder Halbkarton, kaschierte Papiere oder Halbkarton oder metallisierte Papiere oder Halbkarton Anwendung finden.Papers or half-cardboard, laminated papers or half-cardboard or metallized papers or half-cardboard can also be used as carrier materials.

Weitere Trägermaterialien sind Metallfolien, die ein- oder beidseitig mit weiteren Schichten, wie Lackschichten oder Kunststoff-Folien und dergl., beschichtet sind.Further carrier materials are metal foils which are coated on one or both sides with further layers, such as lacquer layers or plastic foils and the like.

Als weiteres Material, zum Schutze der Leiterbahnen, können die als Trägermaterialien genannten Folien und Papiere verwendet werden. Diese Schutzmaterialien können auf dem Trägermaterial, die Leiterbahnen überdeckend, beispielsweise durch kleben, kaschieren usw. festgelegt werden.The films and papers mentioned as carrier materials can be used as a further material for protecting the conductor tracks. These protective materials can be fixed on the carrier material, covering the conductor tracks, for example by gluing, laminating, etc.

Wird eine Etikette auf der Deckelfolie eingesetzt, so ist es vorteilhaft, die Etikette, aus Gründen der Sortenreinheit, aus jeweils den gleichen Materialien wie die Deckelfolie zu gestalten.If a label is used on the cover film, it is advantageous to design the label from the same materials as the cover film for reasons of purity.

Das Material zum Schutze der Leiterbahnen kann auch eine in Form eines Schutzlackes aufgespritzte, aufgesprühte, aufgerollte oder aufgestrichene Schutzschicht darstellen oder dies können aufgedampfte, im Vakuum aufgedampfte oder aufgesputterte Schichten sein.The material for protecting the conductor tracks can also be a protective layer sprayed on, sprayed on, rolled up or spread on in the form of a protective lacquer or these can be vapor-deposited, vacuum-vapor-deposited or sputtered-on layers.

Als Leiterbahnen im Rahmen vorliegender Erfindung werden Leiterbahnen enthaltend eine SnO2/Sb2O3-Hydroxid-Mischung auf einem Mica-Substrat eingesetzt. Vorteilhaft weist die SnO2/Sb2O3-Hydroxid-Mischung eine Schichtdicke auf den Mica-Partikeln von 8 bis 20, vorteilhaft von 16 bis 20 Nanometern, auf. Die SnO2/Sb2O3-Hydroxid-Mischung auf dem Mica-Partikeln stellt ein leitfähiges Pigment dar. Das Verhältnis Sn:Sb beträgt zweckmassig 95:5 bis 75:25, wobei ein Verhältnis von 85:15 bevorzugt ist. Die Korngrösse des Mica kann beispielsweise von 10 bis 100 µm betragen und zweckmässig ist die Korngrösse des Mica kleiner als 15 µm. Damit aus dem leitfähigen Pigment die gewünschten Leiterbahnen erzeugt werden können, muss zweckmassig das leitfähige Pigment in die Form eines Lackes gebracht werden. Ein Lack kann das leitfähige Pigment, die SnO2/Sb2O3-Hydroxid-Mischung auf dem Mica-Substrat, und einen Binder enthalten. Als Binder in solchen Lacken werden beispielsweise Melaminharze, Acrylmelaminharze, Polyurethanlacke, Nitrocellulose-Lacke, Acrylnitrocellulose-Lacke usw. angewendet. Der Binder-Anteil im Lack kann z.B. von 10 bis 60 Gew.-% und vorteilhaft von 10 bis 25 Gew.-% betragen. Entsprechend kann der Anteil an leitfähigem Pigment 40 bis 90 Gew.-% und vorteilhaft von 75 bis 90 Gew.-%, im Lack betragen. Neben dem leitfähigen Pigment kann ein Füllstoff, wie TiO2, beispielsweise in einer Korngrösse von gleich oder Kleiner als 15 µm und in einem Verhältnis von leitfähigem Pigment zu Füllstoff von 1:1 angewendet werden oder es können Füllstoffe in Form von porösen kugelförmigen Teilchen einer Korngrösse von grösser als 30 µm und bekannt unter dem Markennamen LiChrospher der Firma Merck, in einem Verhältnis von leitfähigem Pigment zu Füllstoff von 1:1, angewendet werden.In the context of the present invention, conductor tracks containing an SnO 2 / Sb 2 O 3 hydroxide mixture on a mica substrate are used as conductor tracks. The SnO 2 / Sb 2 O 3 hydroxide mixture advantageously has a layer thickness on the mica particles of 8 to 20, advantageously 16 to 20 nanometers. The SnO 2 / Sb 2 O 3 hydroxide mixture on the mica particles represents a conductive pigment. The ratio Sn: Sb is expedient 95: 5 to 75:25, with a ratio of 85:15 being preferred. The grain size of the mica can be, for example, from 10 to 100 μm and the grain size of the mica is expediently less than 15 μm. So that the desired conductor tracks can be produced from the conductive pigment, the conductive pigment must be appropriately brought into the form of a lacquer. A lacquer can contain the conductive pigment, the SnO 2 / Sb 2 O 3 hydroxide mixture on the mica substrate, and a binder. Melamine resins, acrylic melamine resins, polyurethane lacquers, nitrocellulose lacquers, acrylonitrocellulose lacquers, etc., are used as binders in such lacquers. The proportion of binder in the lacquer can be, for example, from 10 to 60% by weight and advantageously from 10 to 25% by weight. Correspondingly, the proportion of conductive pigment can be 40 to 90% by weight and advantageously 75 to 90% by weight in the lacquer. In addition to the conductive pigment, a filler such as TiO 2 can be used , for example, in a grain size equal to or less than 15 μm and in a ratio of conductive pigment to filler of 1: 1, or fillers in the form of porous spherical particles of a grain size of larger than 30 µm and known under the brand name LiChrospher from Merck, in a ratio of conductive pigment to filler of 1: 1.

Die SnO2/Sb2O3-Hydroxid-Mischung kann beispielsweise durch Fällung mittels Zugabe einer Base zu einer wässrigen Zinn- und Antimonsalz-Lösung erzeugt werden. Dabei wird eine kompakte haftende Schicht um das zugegebene Mica gebildet Diese Verfahrensprodukt in Form eines Pigmentes ist noch nicht elektrisch leitend. Die verlangten elektrischen Eigenschaften werden dem Pigment durch einen anschliessenden Wärmebehandlungsprozess verliehen. Dabei verliert die Metalloxidschicht ihr gebundenes Wasser und das Antimon wird in ein höherwertiges Oxid übergeführt. Somit wird ein Antimon gedoptes Zinndioxid auf Mica erhalten.The SnO 2 / Sb 2 O 3 hydroxide mixture can be produced, for example, by precipitation by adding a base to an aqueous tin and antimony salt solution. A compact adhesive layer is formed around the added mica. This process product in the form of a pigment is not yet electrically conductive. The required electrical properties are imparted to the pigment by a subsequent heat treatment process. The metal oxide layer loses its bound water and the antimony is converted into a higher quality oxide. An antimony-doped tin dioxide on mica is thus obtained.

Die Lacke können auf das Trägermaterial durch aufpinseln, aufstreichen, aufrollen, aufspritzen oder aufsprühen, gegebenenfalls mit Schablone, durch aufdrucken durch Offset-, Tief-, Hoch- oder Siebdruck etc. erfolgen. Andere Verfahren zur Erzeugung von Leiterbahnen auf einem Träger sind das Aufbringen der Leiterbahnen auf den Träger durch ein Abziehbildprinzip oder durch photochemische Reproduktionsverfahren oder photochemische Druckverfahren, wie u.a. durch aufbringen eines vollflächigen Lackfilmes, fixieren des Leiterbahnmusters und ablösen der nicht benötigten Lackflächen.The lacquers can be applied to the carrier material by brushing, brushing, rolling up, spraying on or spraying on, if necessary using a stencil, by printing by means of offset, gravure, letterpress or screen printing, etc. Other methods for producing conductor tracks on a carrier are the application of the conductor tracks to the carrier by a decal principle or by photochemical reproduction processes or photochemical printing processes, such as i.a. by applying a full-surface paint film, fixing the conductor pattern and removing the paint surfaces that are not required.

Die erfindungsgemässen Leiterbahnen können transparent sein oder können auch eingefärbt werden. Die Leiterbahnen oder die Lacke zur Erzeugung der Leiterbahnen können auch weitere leitende oder nichtleitende Stoffe, wie Metallpulver, Pigmente oder Hilfsstoffe, wie Stabilisatoren, Verdicker, Lösungsmittel, Suspensionshilfsmittel, Emulgatoren usw. enthalten.The conductor tracks according to the invention can be transparent or can also be colored. The conductor tracks or the lacquers for producing the conductor tracks can also contain other conductive or non-conductive substances, such as metal powder, pigments or auxiliaries Stabilizers, thickeners, solvents, suspension aids, emulsifiers, etc. contain.

Neben dem gewünschten Muster der Leiterbahn oder der Leiterbahnen auf der Deckelfolie oder dem Etikett, können Erkennungs- und Distanzmarken oder Schaltkreise zum maschinellen Aufbringen der Deckelfolien oder der Etiketten auf eine Blisterpackung vorgesehen werden. Es können neben den Leiterbahnen auch Schaltkreise aufgebracht werden, welche für den Rechner auswertbare Informationen enthalten, wie z.B. über den Inhalt der Packung, die Zusammensetzung, die Dosierung des Produktes, den Einnahmezyklus, das Verfalldatum usw.In addition to the desired pattern of the conductor track or the conductor tracks on the cover film or the label, detection and spacing marks or circuits for mechanically applying the cover films or the labels to a blister pack can be provided. In addition to the conductor tracks, circuits can also be applied which contain information that can be evaluated by the computer, such as about the contents of the pack, the composition, the dosage of the product, the intake cycle, the expiry date, etc.

Die Leiterbahnen können in Serie oder parallel über die Vertiefungen geführt werden und entsprechend kann eine Leiterbahn über alle Vertiefungen gelegt oder es kann je eine Leiterbahn über eine von mehreren Serien von Vertiefungen gelegt werden oder jede Vertiefung kann von einer einzelnen Leiterbahn überdeckt sein und jede Leiterbahn weist einen eigenen Anschluss zum Rechner auf. Diese Leiterbahnen können ihre Information über einen Anschluss zum Rechner leiten.The conductor tracks can be run in series or in parallel over the depressions and accordingly a conductor track can be placed over all depressions or one conductor track can be placed over one of several series of depressions or each depression can be covered by a single conductor track and each conductor track has its own connection to the computer. These conductor tracks can convey their information via a connection to the computer.

Der Rechner kann aufgrund der Information einer unterbrochenen Leiterbahn ein im Rechner vorgegebenes oder durch einen Schaltkreis auf der Deckelfolie oder der Etikette ausgelöstes Zeitintervallprogramm mit der Anzeige der richtigen Einnahmezeit für die nächste Tablette beginnen und die Einnahmezeiten entsprechend dem Programm anzeigen. Es kann auch der Entnahmezeitpunkt durch den Rechner registriert werden und darauf basierend kann der Rechner den nächstfälligen Einnahmezeitpunkt ermitteln und angeben. die Angabe des Entnahmezeitpunktes kann durch verschiedene Kontrollbefehle, wie einen Display mit Zeitangabe, durch farbige Leuchtdioden, akustisch durch einen Warnton und dergl.oder durch eine Kombination der Kontrollbefehle, erfolgen.On the basis of the information of an interrupted conductor track, the computer can start a time interval program, which is predetermined in the computer or triggered by a circuit on the cover film or the label, with the display of the correct intake time for the next tablet and display the intake times according to the program. The time of withdrawal can also be registered by the computer and based on this the computer can determine and indicate the next due time of taking. The time of removal can be specified by various control commands, such as a display with time, by colored light-emitting diodes, acoustically by a warning tone and the like, or by a combination of the control commands.

Ist jede Vertiefung von einer Leiterbahn überdeckt, kann der Rechner feststellen, ob die Packung noch unangebrochen ist oder aufgrund von teilweise durch Medikamententhahme unterbrochenen Leiterbahnen den Medikationsstand errechnen und mit dem geeigneten Einnahmeintervall fortfahren.If each well is covered by a conductor track, the computer can determine whether the package has not yet been opened or whether the medication level is being broken due to conductor tracks partially interrupted by medication and continue with the appropriate intake interval.

Die Leiterbahnen können an einer Seite der Deckelfolie oder der Etikette zusammengeführt und so angeordnet werden, dass der Rechner dort an der Arzneimittelverpackung und/oder and der Etikette festgelegt werden kann und die Leiterbahnen und die Rechneranschlüsse in Kontakt treten können.The conductor tracks can be brought together on one side of the cover film or the label and arranged in such a way that the computer can be fixed there on the pharmaceutical packaging and / or on the label and the conductor tracks and the computer connections can come into contact.

Wird eine Etikette verwendet, kann beispielsweise die Etikette eine Kleberschicht enthalten und mittels der Kleberschicht auf dem Deckelmaterial angebracht sein.If a label is used, the label can, for example, contain an adhesive layer and be attached to the lid material by means of the adhesive layer.

In der Regel können als Bodenteilmaterialien die von Blisterpackungen bekannten Bodenteil- und zur Anwendung gelangen.As a rule, the bottom part materials and blister packs known can be used as bottom part materials.

Vorliegende Deckelfolie kann auch zum Verschliessen oder Überdecken von anderem Stückgut in Einzelabteilen verwendet werden. Beispielsweise können Kleinteile in Blisterpackungen untergebracht sein und Etiketten können die Blisterpackungen abdecken. Durch die Entnahme einzelner Kleinteile wird die Leiterbahn unterbrochen und es kann z.B. ein Sicherheitssystem gegen unbefugte Entnahme aktiviert werden oder der Impuls kann einem Rechner zur Lagerhaltungskontrolle oder dergleichen zugeführt werden.The present cover film can also be used to close or cover other piece goods in individual compartments. For example, small parts can be accommodated in blister packs and labels can cover the blister packs. The trace is interrupted by the removal of individual small parts and e.g. a security system against unauthorized removal can be activated or the pulse can be fed to a computer for inventory control or the like.

Vorliegende Erfindung betrifft auch die Verwendung einer eine SnO2/Sb2O3-Hydroxid-Mischung auf einem Mica-Substrat für Leiterbahnen auf Deckelfolien von Arzneimittelverpackungen.The present invention also relates to the use of an SnO 2 / Sb 2 O 3 hydroxide mixture on a mica substrate for conductor tracks on cover films of pharmaceutical packaging.

Die Figuren 1 und 2 erläutern vorliegende Erfindung beispielhaft näher. Die Figur 1 zeigt eine Draufsicht auf eine Arzneimittelverpackung, wie eine Blisterpackung 1 mit ihren Vertiefungen 2. Ein Rechner 5 ist mittels einer Klemm-, Einrast-, Einschnapp- oder einer anderen Kontaktverbindung mit der Blisterpackung 1 verbunden. Mittels eines Schiebers 4 kann beispielsweise die Klemmverbindung aktiviert werden und die an der Seitenkante 9 der Blisterpackung 1 endenden Leiterbahnen 3 (siehe Figur 2) werden mit Gegenkontakten am Rechner in Verbindung gebracht Der Rechner 5 weist beispielsweise eine Zeitanzeige 6 und/oder eine Anzeige für den Zeitpunkt der nächsten Medikamenteneinnahme und/oder einen Tonerzeuger auf. Durch Leuchtdioden 7 kann der Erinnerungsvorgang für den Patienten erkennbar gemacht oder optisch noch verstärkt werden. Der Rechner ist mehrfach verwendbar und kann beispielsweise durch eine Taste 8 wieder auf Null gesetzt werden. Die Figur 2 zeigt die Rückseite der Blisterverpackung 1. Über den Vertiefungen 2 ist ein Muster von Leiterbahnen 3 gelegt. Jede Vertiefung ist von einer Leiterbahn 3 überdeckt, damit bei erfolgter Medikamentenentnahme und damit Bruch der Leiterbahn 3, ein Impuls an den Rechner 3 gesandt werden kann, resp. dass der Rechner 3 aufgrund ausgesendeter Impulse erkennt, dass die Medikamentenentnahme erfolgt ist oder fällig oder überfällig ist. Der Rechner 5 ist so ausgelegt, dass die Kontakte entlang der Seitenkante 9 der Blisterpackung 1 abgenommen werden können.FIGS. 1 and 2 explain the present invention in more detail by way of example. FIG. 1 shows a top view of a pharmaceutical packaging, such as a blister pack 1 with its depressions 2. A computer 5 is connected to the blister pack 1 by means of a clamp, snap-in, snap-in or other contact connection. By means of a slide 4, for example, the clamp connection can be activated and the conductor tracks 3 (see FIG. 2) ending on the side edge 9 of the blister pack 1 are connected to counter contacts on the computer. The computer 5 has, for example, a time display 6 and / or a display for the Time of next medication and / or a sound generator. The memory process for the patient can be made recognizable or optically enhanced by light-emitting diodes 7. The computer can be used several times and can be reset to zero, for example, using a key 8. FIG. 2 shows the back of the blister pack 1. A pattern of conductor tracks 3 is placed over the depressions 2. Each depression is covered by a conductor track 3, so that when medication has been taken and the conductor track 3 has broken, a pulse can be sent to the computer 3, respectively. that the computer 3 recognizes on the basis of emitted pulses that the medication has been withdrawn or is due or overdue. The computer 5 is designed such that the contacts can be removed along the side edge 9 of the blister pack 1.
