Definitions

  • the invention relates to a method for producing blister packs for medical products, in particular tablets, capsules or dragees, and a corresponding blister pack.
  • Blister packs for medical products are usually produced by molding a plurality of blister cups into a base film, which are then filled with the medical products. A cover film is then sealed onto the base film, so that a sealed blister strip is formed, and individual blister packs are finally punched out of the blister strip.
  • inserts made of active material are usually placed in a chamber connected to the blister cup before the blister cup is sealed with the cover film, see e.g. WO 96/07601 A1 .
  • the blister packs produced using the known method have an increased space requirement due to the additional insert made of active material.
  • the inserts made of active material have to be introduced into relatively complex shaped chambers of the blister cups so that they do not fall out of the blister cup when the user pushes out the blister cup and can be accidentally taken with it. This makes the manufacturing process more difficult.
  • the strips of active material are preferably provided by providing a web of active material wound into a roll and punching out the strips of active material from the unwound web. This enables the strips of active material to be provided in large numbers.
  • the strips of active material are preferably film sections. As a result, the strips of active material are particularly easy to seal with the cover film and only require a small amount of space in terms of height.
  • the strips of active material have a thickness of 0.2 mm to 2 mm, more preferably 0.3 mm to 1.2 mm.
  • the specified thickness of the strips of active material allows safe handling and reduces the space requirement.
  • the active material preferably has an intake function for absorbing at least one substance or a release function for releasing at least one substance.
  • the integrity of the medical products located in the wells can also be ensured over a longer period of time.
  • the strips of active material are deposited using a pick & place device. This ensures the required accuracy when placing the strips of active material and achieves a high throughput.
  • the strips of active material After the strips of active material have been deposited on the contact surfaces of the first recess, the strips of active material preferably protrude by 0.05 mm to 0.5 mm, more preferably by 0.08 mm to 0.2 mm, beyond the webs of the base film. This ensures that when the cover film is subsequently sealed, the cover film is also sealed to the strips of active material, while the cover film is also sealed to the strips due to the only slight protrusion of the strips of active material over the webs of the base film and the compressibility of the strips of active material Webbing of the bottom foil takes place in the same operation.
  • an upwardly protruding rib running around the second recess or at least two spaced-apart, upwardly protruding knobs are formed in a bottom area of the first recess, which the support surface or forms or forms bearing surfaces for the respective strip of active material.
  • the blister pack produced according to the invention for medical products, in particular tablets, capsules or dragees, comprises a base film into which at least one blister cup is molded, which is surrounded by webs of the base foil, the at least one blister cup having an at least two-stage shape such that it has has a first recess which defines a first step of the blister cup, and has a second recess which is arranged in a section of a surface area spanned by the first recess and is lower than the first recess.
  • the blister pack also has a cover film which covers the at least one blister cup and is sealed to the webs of the bottom film, as well as a strip of active material which is arranged in the at least one blister cup and is sealed to the cover film.
  • the medical product is received in the second recess and the strip of active material is received in the first recess, the strip of active material resting on at least one, preferably at least two, bearing surfaces in a bottom area of the first recess, which is arranged next to the second recess or are.
  • This configuration ensures that the active material and the medical products are separated from one another within each cup and, at the same time, the active material remains adhered to the cover film when the medical products are pressed out. In addition, the space requirement of each blister cup is minimized with this arrangement.
  • the blister pack 2 comprises a base film 6, in which at least one blister cup 8 is molded, which is surrounded by webs 10 of the base film 6.
  • the in Fig. 1 The section of the blister pack 2 shown here shows only one blister cup 8.
  • blister packs 2 have a plurality of blister cups 8, which are usually distributed over the blister pack 2 in a regular pattern.
  • a frequently used arrangement of the blister cups 8 in the blister pack 2 is a matrix of rows and columns.
  • a cover film 12 which covers the at least one blister cup 8, is sealed to the webs 10 of the bottom film 6 and closes the at least one blister cup 8.
  • the cover film 12 is only in Fig. 3 shown while in Fig. 1 and 2 has been omitted for the sake of clarity.
  • PVC, PVDC, Aclar, aluminum, PETG or composite films are particularly suitable as the material for the floor film.
  • Particularly suitable materials for the cover film are aluminum, polyethylene, polypropylene, paper-laminated and other composite films.
  • a strip 14 of active material is arranged in at least one blister cup 8 and sealed to the cover film 12.
  • the sealing with the cover film 12 can be over the entire surface, only over certain surface areas of the strip 14, along lines or also only selectively.
  • the active material Due to its material properties, the active material generally has an absorption function for absorbing at least one substance or a release function for delivery at least one substance. The most common use is to absorb moisture. In the case of strips 14 with an absorbing function, the strips 14 made of active material can also absorb oxygen, CO 2 , reactive contaminants or odors, for example. In the case of strips 14 with a release function, the strips 14 made of active material can release nitrogen or carbon dioxide, for example.
  • a strip 14 of active material preferably has a thickness of 0.2 mm to 2 mm, more preferably 0.3 mm to 1.2 mm.
  • the material of the strip 14 is preferably at least a little rigid in order to simplify handling.
  • the material of the strip 14 is preferably a film, more preferably a polymer, particularly preferably a three-phase polymer.
  • the film can be produced, for example, by extrusion, the active particles being added to the polymer. Channels within the polymer allow gases to move.
  • the active particles are preferably present as spheres in the strip 14 made of active material.
  • the product 4 is designed as an oblong and the strip 14 of active material has a substantially rectangular base area.
  • the strip 14 is arranged transversely to the product 4, preferably at an angle of approximately 45 °. Usual dimensions of the strip 14 in the longitudinal and transverse directions are approximately 5 mm to 50 mm.
  • each blister cup 8 comprises a two-step shape, in which a first recess 16 defines a first step of the blister cup 8.
  • a second recess 18 is arranged in a subsection of the surface area spanned by the first recess 16 and is lower than the first recess 16.
  • the medical product 4 is received in the second recess 18, while the strip 14 of active material is received in the first recess 16 is.
  • the strip 14 made of active material rests on contact surfaces 20 of the first recess 16, which are arranged next to the second recess 18.
  • the strip 14 and the product 4 are thus preferably spaced apart from one another in the vertical direction.
  • the two bearing surfaces 20 for the strip 14 made of active material are diametrically opposite one another on two sides of the second recess 18.
  • the strip 14 made of active material thus covers a large part of the second recess 18 and rests on the bearing surfaces 20 with two opposite corner regions.
  • the illustrated embodiment of the blister pack 2 according to the invention is constructed similarly to that in FIG Figs. 1 to 3 illustrated and previously described embodiment. Identical elements are provided with the same reference symbols.
  • the medical product 4 has a circular base area.
  • the strip 14 made of active material in turn has an essentially rectangular base area and rests with its two narrower edge regions on the bearing surfaces 20 which are arranged on opposite sides of the second recess 18. The strip 14 made of active material thus covers essential parts of the product 4.
  • the illustrated embodiment of the blister pack 2 according to the invention is again essentially identical to the embodiment according to FIG Figs. 1 to 3 .
  • Identical elements are provided with identical reference symbols.
  • the medical product 4 is designed as a sphere.
  • the strip 14 made of active material has a recess 22 which is arranged above the medical product 4.
  • the medical product 4 can thus pass through the recess 22 of the strip 14 made of active material when it is being squeezed out.
  • the area of the cover film 12 sealed with the strip 14 of active material is thus not broken when the product 4 is pressed out, but only the area of the cover film 12 above the cutout 22.
  • the shape of the blister cups 8 can differ from the designs described so far. Any geometric configuration is conceivable, provided that the blister cup 8 has at least a two-step shape.
  • the shape of the second recess 18 is preferably based on the shape of the product 4 to be packaged, which can have all possible geometric shapes. In addition to the oblong shape, tablet shape or spherical shape shown so far, triangular or polygonal shapes of the medical products 4 are also possible.
  • the shape of the strip 14 made of active material can also differ from the exemplary embodiments illustrated so far.
  • the strips 14 can in addition to the one shown rectangular base area, for example, also have round, oval, triangular base areas. In each of these configurations it is possible to provide a recess 22 in the strip.
  • the strips 14 are usually blanks.
  • the bearing surfaces 20 for the strips 14 made of active material can be arranged on two opposite sides of the second recess 18, as shown in the previous exemplary embodiments. However, it is also possible that more than two support surfaces 20 are arranged around the second recess 18 or that a single continuous support surface 20, which runs around the second recess 18, is provided.
  • a bottom sheet 6 in the form of a roll is provided and unwound.

Description

Die Erfindung betrifft ein Verfahren zur Herstellung von Blisterverpackungen für medizinische Produkte, insbesondere Tabletten, Kapseln oder Dragees, und eine entsprechende Blisterverpackung.The invention relates to a method for producing blister packs for medical products, in particular tablets, capsules or dragees, and a corresponding blister pack.

Üblicherweise werden Blisterverpackungen für medizinische Produkte hergestellt, indem in eine Bodenfolie eine Mehrzahl von Blisternäpfen eingeformt wird, die anschließend mit den medizinischen Produkten befüllt werden. Daraufhin wird eine Deckfolie auf die Bodenfolie aufgesiegelt, so dass eine versiegelte Blisterbahn gebildet wird, und schließlich werden einzelne Blisterverpackungen aus der Blisterbahn ausgestanzt.Blister packs for medical products are usually produced by molding a plurality of blister cups into a base film, which are then filled with the medical products. A cover film is then sealed onto the base film, so that a sealed blister strip is formed, and individual blister packs are finally punched out of the blister strip.

Bei bestimmten medizinischen Produkten kann es notwendig sein, im Bereich des Blisternapfes zusätzlich eine Einlage aus Aktivmaterial vorzusehen, die beispielsweise der Trocknung der im versiegelten Napf befindlichen Luft dient, um die Integrität des medizinischen Produkts zu gewährleisten. Üblicherweise werden dazu Einlagen aus Aktivmaterial in eine mit dem Blisternapf verbundene Kammer eingelegt, bevor der Blisternapf mit der Deckfolie versiegelt wird, siehe z.B. WO 96/07601 A1 .In the case of certain medical products, it may be necessary to additionally provide an insert made of active material in the area of the blister cup, which is used, for example, to dry the air in the sealed cup in order to ensure the integrity of the medical product. For this purpose, inserts made of active material are usually placed in a chamber connected to the blister cup before the blister cup is sealed with the cover film, see e.g. WO 96/07601 A1 .

Die mit den bekannten Verfahren hergestellten Blisterverpackungen haben allerdings aufgrund der zusätzlichen Einlage aus Aktivmaterial einen erhöhten Platzbedarf. Außerdem müssen die Einlagen aus Aktivmaterial in relativ komplex geformte Kammern der Blisternäpfe eingebracht werden, damit sie beim Ausdrücken des Blisternapfes durch den Nutzer nicht aus dem Blisternapf fallen und versehentlich mit eingenommen werden können. Dadurch wird der Herstellprozess erschwert.The blister packs produced using the known method, however, have an increased space requirement due to the additional insert made of active material. In addition, the inserts made of active material have to be introduced into relatively complex shaped chambers of the blister cups so that they do not fall out of the blister cup when the user pushes out the blister cup and can be accidentally taken with it. This makes the manufacturing process more difficult.

Es ist somit die Aufgabe der vorliegenden Erfindung, ein möglichst einfaches Verfahren zur Herstellung von Blisterverpackungen für medizinische Produkte mit einem Aktivmaterial im Bereich der Näpfe der Blisterverpackungen zu schaffen, so dass die Blisterverpackungen wenig Platz beanspruchen und sicher in der Handhabung sind, und eine entsprechende Blisterverpackung zu schaffen.It is therefore the object of the present invention to create the simplest possible method for producing blister packs for medical products with an active material in the area of the wells of the blister packs, so that the blister packs take up little space and are safe to handle, and a corresponding blister pack to accomplish.

Diese Aufgabe wird durch die Merkmale des Anspruchs 1 bzw. des Anspruchs 9 gelöst.This object is achieved by the features of claim 1 and claim 9, respectively.

Erfindungsgemäß umfasst das Verfahren zur Herstellung von Blisterverpackungen für medizinische Produkte, insbesondere Tabletten, Kapseln oder Dragees folgende Schritte:

  • Bereitstellen einer Bodenfolie und Formen einer Mehrzahl von Blisternäpfen in die Bodenfolie, wobei jeder Blisternapf eine mindestens zweistufige Form aufweist derart, dass er eine erste Ausnehmung aufweist, die eine erste Stufe des Blisternapfes definiert, und eine zweite Ausnehmung aufweist, die in einem Teilabschnitt eines von der ersten Ausnehmung überspannten Flächenbereichs angeordnet ist und tiefer liegt als die erste Ausnehmung;
  • Befüllen der zweiten Ausnehmungen der Blisternäpfe mit den medizinischen Produkten;
  • Bereitstellen von Streifen aus Aktivmaterial und Ablegen jeweils eines Streifens aus Aktivmaterial in die erste Ausnehmung jedes Blisternapfes oberhalb des medizinischen Produkts, wobei der Streifen aus Aktivmaterial auf mindestens einer, bevorzugt mindestens zwei Auflageflächen der ersten Ausnehmung aufliegt, die neben der zweiten Ausnehmung angeordnet ist oder sind;
  • Bereitstellen einer Deckfolie und gleichzeitiges Siegeln der Deckfolie an Stege der Bodenfolie, die um die Blisternäpfe herum angeordnet sind, sowie an die Streifen aus Aktivmaterial und dadurch Bilden einer versiegelten Blisterbahn; und
  • Ausstanzen einzelner Blisterverpackungen aus der Blisterbahn.
According to the invention, the method for producing blister packs for medical products, in particular tablets, capsules or dragees, comprises the following steps:
  • Providing a bottom foil and molding a plurality of blister cups into the bottom foil, each blister cup having an at least two-step shape such that it has a first recess which defines a first step of the blister cup and a second recess which, in a portion of one of the surface region spanned by the first recess is arranged and is lower than the first recess;
  • Filling the second recesses of the blister cups with the medical products;
  • Providing strips of active material and depositing one strip of active material in the first recess of each blister cup above the medical product, the strip of active material resting on at least one, preferably at least two, bearing surfaces of the first recess, which is or are arranged next to the second recess ;
  • Provision of a cover film and simultaneous sealing of the cover film on webs of the base film which are arranged around the blister cups and on the strips of active material and thereby forming a sealed blister sheet; and
  • Punching out individual blister packs from the blister strip.

Durch die gleichzeitige Versiegelung der Deckfolie an die Stege der Bodenfolie und an die Streifen aus Aktivmaterial werden auf einfache Weise Blisterverpackungen hergestellt, die einen relativ geringen Platzbedarf haben und bei denen sichergestellt ist, dass beim Ausdrücken der medizinischen Produkte das Aktivmaterial an der Deckfolie haften bleibt.The simultaneous sealing of the cover film to the webs of the base film and to the strips of active material makes it easy to produce blister packs that require relatively little space and that ensure that the active material adheres to the cover film when the medical products are pressed out.

Vorzugsweise erfolgt das Bereitstellen der Streifen aus Aktivmaterial durch Bereitstellen einer zu einer Rolle aufgewickelten Bahn aus Aktivmaterial und Ausstanzen der Streifen aus Aktivmaterial aus der abgewickelten Bahn. Hierdurch wird das Bereitstellen der Streifen aus Aktivmaterial in großen Stückzahlen ermöglicht.The strips of active material are preferably provided by providing a web of active material wound into a roll and punching out the strips of active material from the unwound web. This enables the strips of active material to be provided in large numbers.

Vorzugsweise sind die Streifen aus Aktivmaterial Folienabschnitte. Dadurch sind die Streifen aus Aktivmaterial besonders einfach mit der Deckfolie zu versiegeln und benötigen in der Höhe lediglich einen geringen Platzbedarf.The strips of active material are preferably film sections. As a result, the strips of active material are particularly easy to seal with the cover film and only require a small amount of space in terms of height.

Dabei ist es besonders bevorzugt, wenn die Streifen aus Aktivmaterial eine Dicke von 0,2 mm bis 2 mm, mehr bevorzugt 0,3 mm bis 1,2 mm aufweisen. Die angegebene Dicke der Streifen aus Aktivmaterial erlaubt eine sichere Handhabung und reduziert den Platzbedarf.It is particularly preferred if the strips of active material have a thickness of 0.2 mm to 2 mm, more preferably 0.3 mm to 1.2 mm. The specified thickness of the strips of active material allows safe handling and reduces the space requirement.

Das Aktivmaterial weist vorzugsweise aufgrund seiner Materialeigenschaften eine Aufnahmefunktion zur Aufnahme mindestens einer Substanz oder eine Abgabefunktion zur Abgabe mindestens einer Substanz auf. Dadurch kann, je nach gewünschter Anforderung, die Integrität der in den Näpfen befindlichen medizinischen Produkte auch über einen längeren Zeitraum sichergestellt werden.Due to its material properties, the active material preferably has an intake function for absorbing at least one substance or a release function for releasing at least one substance. As a result, depending on the desired requirement, the integrity of the medical products located in the wells can also be ensured over a longer period of time.

Es ist bevorzugt, dass das Ablegen der Streifen aus Aktivmaterial mittels einer Pick & Place-Vorrichtung durchgeführt wird. Hierdurch wird die erforderliche Genauigkeit bei der Ablage der Streifen aus Aktivmaterial gewährleistet und ein hoher Durchsatz erzielt.It is preferred that the strips of active material are deposited using a pick & place device. This ensures the required accuracy when placing the strips of active material and achieves a high throughput.

Vorzugsweise stehen nach dem Ablegen der Streifen aus Aktivmaterial auf den Auflageflächen der ersten Ausnehmung die Streifen aus Aktivmaterial um 0,05 mm bis 0,5 mm, mehr bevorzugt um 0,08 mm bis 0,2 mm, über die Stege der Bodenfolie vor. Dadurch wird sichergestellt, dass beim nachfolgenden Versiegeln der Deckfolie die Deckfolie auch an die Streifen aus Aktivmaterial gesiegelt wird, während aufgrund des lediglich geringen Überstands der Streifen aus Aktivmaterial über die Stege der Bodenfolie und der Komprimierbarkeit der Streifen aus Aktivmaterial auch ein Versiegeln der Deckfolie mit den Stegen der Bodenfolie im selben Arbeitsgang stattfindet.After the strips of active material have been deposited on the contact surfaces of the first recess, the strips of active material preferably protrude by 0.05 mm to 0.5 mm, more preferably by 0.08 mm to 0.2 mm, beyond the webs of the base film. This ensures that when the cover film is subsequently sealed, the cover film is also sealed to the strips of active material, while the cover film is also sealed to the strips due to the only slight protrusion of the strips of active material over the webs of the base film and the compressibility of the strips of active material Webbing of the bottom foil takes place in the same operation.

In einer bevorzugten Ausgestaltung werden beim Formen der Mehrzahl von Blisternäpfen in die Bodenfolie auch jeweils eine um die zweite Ausnehmung herum verlaufende, nach oben abragende Rippe oder jeweils mindestens zwei voneinander beabstandete, nach oben abragende Noppen in einem Bodenbereich der ersten Ausnehmung geformt, die die Auflagefläche oder Auflageflächen für den jeweiligen Streifen aus Aktivmaterial bildet oder bilden. Auf diese Weise wird zum einen ein Abstand zwischen den medizinischen Produkten und den Streifen aus Aktivmaterial hergestellt, und zum anderen wird durch den Gegendruck der Rippe oder der mindestens zwei nach oben abragenden Noppen die Siegelqualität zwischen Deckfolie und den Streifen aus Aktivmaterial an diesen Stellen erhöht.In a preferred embodiment, when the plurality of blister cups are formed in the base film, an upwardly protruding rib running around the second recess or at least two spaced-apart, upwardly protruding knobs are formed in a bottom area of the first recess, which the support surface or forms or forms bearing surfaces for the respective strip of active material. In this way, on the one hand, a distance is created between the medical products and the strips of active material, and on the other hand, the counter-pressure of the rib or the at least two upwardly protruding knobs increases the sealing quality between the cover film and the strips of active material at these points.

Die erfindungsgemäß hergestellte Blisterverpackung für medizinische Produkte, insbesondere Tabletten, Kapseln oder Dragees, umfasst eine Bodenfolie, in die mindestens ein Blisternapf eingeformt ist, der von Stegen der Bodenfolie umgeben ist, wobei der mindestens eine Blisternapf eine mindestens zweistufige Form aufweist derart, dass er eine erste Ausnehmung aufweist, die eine erste Stufe des Blisternapfes definiert, und eine zweite Ausnehmung aufweist, die in einem Teilabschnitt eines von der ersten Ausnehmung überspannten Flächenbereichs angeordnet ist und tiefer liegt als die erste Ausnehmung. Die Blisterverpackung weist außerdem eine Deckfolie auf, die den mindestens einen Blisternapf überdeckt und an die Stege der Bodenfolie gesiegelt ist, sowie einen Streifen aus Aktivmaterial, der im mindestens einen Blisternapf angeordnet ist und an die Deckfolie gesiegelt ist. Das medizinische Produkt ist in der zweiten Ausnehmung aufgenommen, und der Streifen aus Aktivmaterial ist in der ersten Ausnehmung aufgenommen, wobei der Streifen aus Aktivmaterial auf mindestens einer, bevorzugt mindestens zwei Auflageflächen in einem Bodenbereich der ersten Ausnehmung aufliegt, die neben der zweiten Ausnehmung angeordnet ist oder sind.The blister pack produced according to the invention for medical products, in particular tablets, capsules or dragees, comprises a base film into which at least one blister cup is molded, which is surrounded by webs of the base foil, the at least one blister cup having an at least two-stage shape such that it has has a first recess which defines a first step of the blister cup, and has a second recess which is arranged in a section of a surface area spanned by the first recess and is lower than the first recess. The blister pack also has a cover film which covers the at least one blister cup and is sealed to the webs of the bottom film, as well as a strip of active material which is arranged in the at least one blister cup and is sealed to the cover film. The medical product is received in the second recess and the strip of active material is received in the first recess, the strip of active material resting on at least one, preferably at least two, bearing surfaces in a bottom area of the first recess, which is arranged next to the second recess or are.

Mit dieser Ausgestaltung wird gewährleistet, dass das Aktivmaterial und die medizinischen Produkte innerhalb jedes Napfes voneinander getrennt sind und gleichzeitig das Aktivmaterial beim Ausdrücken der medizinischen Produkte an der Deckfolie haften bleibt. Außerdem ist bei dieser Anordnung der Platzbedarf jedes Blisternapfes minimiert.This configuration ensures that the active material and the medical products are separated from one another within each cup and, at the same time, the active material remains adhered to the cover film when the medical products are pressed out. In addition, the space requirement of each blister cup is minimized with this arrangement.

In Fig. 1 bis 3 ist eine erste Ausführungsform einer erfindungsgemäßen Blisterverpackung 2 für medizinische Produkte 4, insbesondere Tabletten, Kapseln oder Dragees dargestellt. Die Blisterverpackung 2 umfasst eine Bodenfolie 6, in die mindestens ein Blisternapf 8 eingeformt ist, der von Stegen 10 der Bodenfolie 6 umgeben ist. Der in Fig. 1 dargestellte Ausschnitt der Blisterverpackung 2 zeigt lediglich einen Blisternapf 8. In der Regel weisen Blisterverpackungen 2 eine Mehrzahl von Blisternäpfen 8 auf, die üblicherweise in einem regelmäßigen Muster über die Blisterverpackung 2 verteilt sind. Eine häufig verwendete Anordnung der Blisternäpfe 8 in der Blisterverpackung 2 ist eine Matrix aus Zeilen und Spalten.In Figs. 1 to 3 a first embodiment of a blister pack 2 according to the invention for medical products 4, in particular tablets, capsules or dragees, is shown. The blister pack 2 comprises a base film 6, in which at least one blister cup 8 is molded, which is surrounded by webs 10 of the base film 6. The in Fig. 1 The section of the blister pack 2 shown here shows only one blister cup 8. As a rule, blister packs 2 have a plurality of blister cups 8, which are usually distributed over the blister pack 2 in a regular pattern. A frequently used arrangement of the blister cups 8 in the blister pack 2 is a matrix of rows and columns.

Eine Deckfolie 12, die den mindestens einen Blisternapf 8 überdeckt, ist an die Stege 10 der Bodenfolie 6 gesiegelt und verschließt den mindestens einen Blisternapf 8. Die Deckfolie 12 ist lediglich in Fig. 3 dargestellt, während sie in Fig. 1 und 2 aus Gründen der besseren Übersichtlichkeit weggelassen wurde.A cover film 12, which covers the at least one blister cup 8, is sealed to the webs 10 of the bottom film 6 and closes the at least one blister cup 8. The cover film 12 is only in Fig. 3 shown while in Fig. 1 and 2 has been omitted for the sake of clarity.

Als Material der Bodenfolie kommen insbesondere PVC, PVDC, Aclar, Aluminium, PETG oder Verbundfolien in Frage. Als Material der Deckfolie kommen insbesondere Aluminium, Polyethylen, Polypropylen, papierkaschierte und weitere Verbundfolien in Frage.PVC, PVDC, Aclar, aluminum, PETG or composite films are particularly suitable as the material for the floor film. Particularly suitable materials for the cover film are aluminum, polyethylene, polypropylene, paper-laminated and other composite films.

Ein Streifen 14 aus Aktivmaterial ist im mindestens einen Blisternapf 8 angeordnet und an die Deckfolie 12 gesiegelt. Die Versiegelung mit der Deckfolie 12 kann vollflächig sein, lediglich über gewisse Flächenbereiche des Streifens 14, entlang von Linien oder auch nur punktuell.A strip 14 of active material is arranged in at least one blister cup 8 and sealed to the cover film 12. The sealing with the cover film 12 can be over the entire surface, only over certain surface areas of the strip 14, along lines or also only selectively.

Das Aktivmaterial weist allgemein aufgrund seiner Materialeigenschaften eine Aufnahmefunktion zur Aufnahme mindestens einer Substanz oder eine Abgabefunktion zur Abgabe mindestens einer Substanz auf. Der am weitesten verbreitete Einsatzzweck ist die Aufnahme von Feuchtigkeit. Bei Streifen 14 mit Aufnahmefunktion können die Streifen 14 aus Aktivmaterial aber beispielsweise auch Sauerstoff, CO2, reaktive Verunreinigungen oder Gerüche aufnehmen. Bei Streifen 14 mit Abgabefunktion können die Streifen 14 aus Aktivmaterial beispielsweise Stickstoff oder Kohlendioxid freisetzen.Due to its material properties, the active material generally has an absorption function for absorbing at least one substance or a release function for delivery at least one substance. The most common use is to absorb moisture. In the case of strips 14 with an absorbing function, the strips 14 made of active material can also absorb oxygen, CO 2 , reactive contaminants or odors, for example. In the case of strips 14 with a release function, the strips 14 made of active material can release nitrogen or carbon dioxide, for example.

Ein Streifen 14 aus Aktivmaterial weist vorzugsweise eine Dicke von 0,2 mm bis 2 mm, mehr bevorzugt von 0,3 mm bis 1,2 mm auf. Das Material des Streifens 14 ist vorzugsweise zumindest ein wenig biegesteif, um die Handhabung zu vereinfachen. Das Material des Streifens 14 ist vorzugsweise eine Folie, mehr bevorzugt ein Polymer, besonders bevorzugt ein Dreiphasen-Polymer. Die Folie kann beispielsweise durch Extrusion hergestellt werden, wobei die aktiven Partikel dem Polymer beigefügt werde. Kanäle innerhalb des Polymers ermöglichen eine Bewegung von Gasen. Vorzugsweise liegen die aktiven Partikel als Sphären im Streifen 14 aus Aktivmaterial vor.A strip 14 of active material preferably has a thickness of 0.2 mm to 2 mm, more preferably 0.3 mm to 1.2 mm. The material of the strip 14 is preferably at least a little rigid in order to simplify handling. The material of the strip 14 is preferably a film, more preferably a polymer, particularly preferably a three-phase polymer. The film can be produced, for example, by extrusion, the active particles being added to the polymer. Channels within the polymer allow gases to move. The active particles are preferably present as spheres in the strip 14 made of active material.

In der Ausführungsform gemäß Fig. 1 bis 3 ist das Produkt 4 als Oblong ausgebildet und der Streifen 14 aus Aktivmaterial weist eine im Wesentlichen rechteckige Grundfläche auf. Der Streifen 14 ist quer zum Produkt 4 angeordnet, bevorzugt unter einem Winkel von ca. 45°. Übliche Abmessungen des Streifens 14 in Längs- und Querrichtung sind ca. 5 mm bis 50 mm.In the embodiment according to Figs. 1 to 3 the product 4 is designed as an oblong and the strip 14 of active material has a substantially rectangular base area. The strip 14 is arranged transversely to the product 4, preferably at an angle of approximately 45 °. Usual dimensions of the strip 14 in the longitudinal and transverse directions are approximately 5 mm to 50 mm.

Wie aus Fig. 3 ersichtlich ist, umfasst jeder Blisternapf 8 eine zweistufige Form, bei der eine erste Ausnehmung 16 eine erste Stufe des Blisternapfes 8 definiert. Eine zweite Ausnehmung 18 ist in einem Teilabschnitt des von der ersten Ausnehmung 16 überspannten Flächenbereichs angeordnet und liegt tiefer als die erste Ausnehmung 16. Das medizinische Produkt 4 ist in der zweiten Ausnehmung 18 aufgenommen, während der Streifen 14 aus Aktivmaterial in der ersten Ausnehmung 16 aufgenommen ist. Der Streifen 14 aus Aktivmaterial liegt dabei auf Auflageflächen 20 der ersten Ausnehmung 16 auf, die neben der zweiten Ausnehmung 18 angeordnet sind. Der Streifen 14 und das Produkt 4 sind somit vorzugsweise voneinander in vertikaler Richtung beabstandet.How out Fig. 3 As can be seen, each blister cup 8 comprises a two-step shape, in which a first recess 16 defines a first step of the blister cup 8. A second recess 18 is arranged in a subsection of the surface area spanned by the first recess 16 and is lower than the first recess 16. The medical product 4 is received in the second recess 18, while the strip 14 of active material is received in the first recess 16 is. The strip 14 made of active material rests on contact surfaces 20 of the first recess 16, which are arranged next to the second recess 18. The strip 14 and the product 4 are thus preferably spaced apart from one another in the vertical direction.

Die beiden Auflageflächen 20 für den Streifen 14 aus Aktivmaterial liegen sich auf zwei Seiten der zweiten Ausnehmung 18 diametral gegenüber. Der Streifen 14 aus Aktivmaterial überdeckt somit einen Großteil der zweiten Ausnehmung 18 und liegt mit zwei gegenüberliegenden Eckbereichen auf den Auflageflächen 20 auf.The two bearing surfaces 20 for the strip 14 made of active material are diametrically opposite one another on two sides of the second recess 18. The strip 14 made of active material thus covers a large part of the second recess 18 and rests on the bearing surfaces 20 with two opposite corner regions.

Die in Fig. 4 bis 7 dargestellte Ausführungsform der erfindungsgemäßen Blisterverpackung 2 ist ähnlich aufgebaut wie die in Fig. 1 bis 3 dargestellte und zuvor beschriebene Ausführungsform. Identische Elemente sind mit denselben Bezugszeichen versehen. Im Unterschied zu der Ausführungsform aus Fig. 1 bis 3 weist das medizinische Produkt 4 eine kreisförmige Grundfläche auf. Der Streifen 14 aus Aktivmaterial besitzt wiederum eine im Wesentlichen rechteckige Grundfläche und liegt mit seinen zwei schmaleren Randbereichen auf den Auflageflächen 20 auf, die an gegenüberliegenden Seiten der zweiten Ausnehmung 18 angeordnet sind. Der Streifen 14 aus Aktivmaterial überdeckt somit wesentliche Teile des Produkts 4.In the Figures 4 to 7 The illustrated embodiment of the blister pack 2 according to the invention is constructed similarly to that in FIG Figs. 1 to 3 illustrated and previously described embodiment. Identical elements are provided with the same reference symbols. In contrast to the embodiment Figs. 1 to 3 the medical product 4 has a circular base area. The strip 14 made of active material in turn has an essentially rectangular base area and rests with its two narrower edge regions on the bearing surfaces 20 which are arranged on opposite sides of the second recess 18. The strip 14 made of active material thus covers essential parts of the product 4.

Die in Fig. 8 bis 11 dargestellte Ausführungsform der erfindungsgemäßen Blisterverpackung 2 ist wiederum im Wesentlichen identisch zur Ausführungsform gemäß Fig. 1 bis 3. Identische Elemente sind mit identischen Bezugszeichen versehen. Das medizinische Produkt 4 ist als Kugel ausgebildet. Im Gegensatz zu den zuvor beschriebenen Ausführungsformen besitzt der Streifen 14 aus Aktivmaterial eine Aussparung 22, die über dem medizinischen Produkt 4 angeordnet ist. Das medizinische Produkt 4 kann somit beim Ausdrücken durch die Aussparung 22 des Streifens 14 aus Aktivmaterial hindurchtreten. Der mit dem Streifen 14 aus Aktivmaterial versiegelte Bereich der Deckfolie 12 wird somit beim Ausdrücken des Produkts 4 nicht durchbrochen, sondern lediglich der Bereich der Deckfolie 12 oberhalb der Aussparung 22.In the Figs. 8-11 The illustrated embodiment of the blister pack 2 according to the invention is again essentially identical to the embodiment according to FIG Figs. 1 to 3 . Identical elements are provided with identical reference symbols. The medical product 4 is designed as a sphere. In contrast to the embodiments described above, the strip 14 made of active material has a recess 22 which is arranged above the medical product 4. The medical product 4 can thus pass through the recess 22 of the strip 14 made of active material when it is being squeezed out. The area of the cover film 12 sealed with the strip 14 of active material is thus not broken when the product 4 is pressed out, but only the area of the cover film 12 above the cutout 22.

Die Form der Blisternäpfe 8 kann von den bislang beschriebenen Ausgestaltungen abweichen. Denkbar ist jede geometrische Ausgestaltung, sofern der Blisternapf 8 eine mindestens zweistufige Gestalt besitzt. Die Gestalt der zweiten Ausnehmung 18 richtet sich dabei vorzugsweise nach der Form des zu verpackenden Produkts 4, das alle möglichen geometrischen Formen besitzen kann. Neben der bislang dargestellten Oblong-Form, Drageeform oder Kugelform kommen auch dreieckige oder mehreckige Formen der medizinischen Produkte 4 in Frage.The shape of the blister cups 8 can differ from the designs described so far. Any geometric configuration is conceivable, provided that the blister cup 8 has at least a two-step shape. The shape of the second recess 18 is preferably based on the shape of the product 4 to be packaged, which can have all possible geometric shapes. In addition to the oblong shape, tablet shape or spherical shape shown so far, triangular or polygonal shapes of the medical products 4 are also possible.

Schließlich kann auch die Form des Streifens 14 aus Aktivmaterial von den bislang dargestellten Ausführungsbeispielen abweichen. Die Streifen 14 können neben der dargestellten rechteckigen Grundfläche beispielsweise auch runde, ovale, dreieckige Grundflächen aufweisen. In jeder dieser Ausgestaltungen ist es möglich, eine Aussparung 22 in dem Streifen vorzusehen. Die Streifen 14 sind in der Regel Zuschnitte.Finally, the shape of the strip 14 made of active material can also differ from the exemplary embodiments illustrated so far. The strips 14 can in addition to the one shown rectangular base area, for example, also have round, oval, triangular base areas. In each of these configurations it is possible to provide a recess 22 in the strip. The strips 14 are usually blanks.

Die Auflageflächen 20 für die Streifen 14 aus Aktivmaterial können auf zwei gegenüberliegenden Seiten der zweiten Ausnehmung 18 angeordnet sein, wie in den bisherigen Ausführungsbeispielen dargestellt. Ebenso ist es aber möglich, dass mehr als zwei Auflageflächen 20 um die zweite Ausnehmung 18 herum angeordnet sind oder dass eine einzige durchgängige Auflagefläche 20, die um die zweite Ausnehmung 18 herum verläuft, vorgesehen ist.The bearing surfaces 20 for the strips 14 made of active material can be arranged on two opposite sides of the second recess 18, as shown in the previous exemplary embodiments. However, it is also possible that more than two support surfaces 20 are arranged around the second recess 18 or that a single continuous support surface 20, which runs around the second recess 18, is provided.

Bezugnehmend auf Fig. 12 wird nun ein erfindungsgemäßes Verfahren zur Herstellung von Blisterverpackungen 2 beschrieben. Zunächst wird eine Bodenfolie 6 in Form einer Rolle bereitgestellt und abgewickelt. In die abgewickelte Bodenfolie 6 werden in einer Formstation 24 die Blisternäpfe 8 geformt, wobei jeder Blisternapf 8 die zuvor beschriebene, mindestens zweistufige Form aufweist. Anschließend werden in einer Füllstation 26 die zweiten Ausnehmungen 18 der Blisternäpfe 8 mit den medizinischen Produkten 4 befüllt.Referring to Fig. 12 A method according to the invention for producing blister packs 2 will now be described. First, a bottom sheet 6 in the form of a roll is provided and unwound. The blister cups 8 are formed in the unwound base film 6 in a forming station 24, each blister cup 8 having the above-described, at least two-stage shape. The second recesses 18 of the blister cups 8 are then filled with the medical products 4 in a filling station 26.

In einer Zuführstation 28 werden anschließend Streifen 14 aus Aktivmaterial bereitgestellt und jeweils ein Streifen 14 aus Aktivmaterial wird in die erste Ausnehmung 16 jedes Blisternapfes 8 oberhalb des medizinischen Produkts 4 auf der mindestens einen Auflagefläche 20 der ersten Ausnehmung 16 abgelegt. Der Streifen 14 aus Aktivmaterial ist somit vorzugsweise oberhalb vom medizinischen Produkt 4 angeordnet, vorzugsweise in einem geringen Abstand davon. Bevorzugt erfolgt das Bereitstellen der Streifen 14 aus Aktivmaterial durch Bereitstellen einer zu einer Rolle aufgewickelten Bahn aus Aktivmaterial und Ausstanzen der Streifen 14 aus Aktivmaterial aus der abgewickelten Bahn. Das Ablegen der Streifen 14 aus Aktivmaterial erfolgt vorzugsweise mittels einer Pick & Place-Vorrichtung. Es ist aber auch möglich, andere Übergabeformen für die Streifen 14 aus Aktivmaterial vorzusehen.In a feed station 28, strips 14 of active material are then provided and in each case a strip 14 of active material is placed in the first recess 16 of each blister cup 8 above the medical product 4 on the at least one support surface 20 of the first recess 16. The strip 14 made of active material is thus preferably arranged above the medical product 4, preferably at a small distance therefrom. The strips 14 of active material are preferably provided by providing a web of active material wound into a roll and punching out the strips 14 of active material from the unwound web. The strips 14 of active material are preferably deposited by means of a pick & place device. However, it is also possible to provide other forms of transfer for the strips 14 made of active material.

In einer nachfolgenden Siegelstation 30 wird die Deckfolie 12 bereitgestellt und an Stege 10 der Bodenfolie 6 angesiegelt. Gleichzeitig wird die Deckfolie 12 auch an die Streifen 14 aus Aktivmaterial angesiegelt. Insgesamt wird auf diese Weise eine versiegelte Blisterbahn gebildet. Schließlich erfolgt in einer nachgelagerten Stanzstation 32 das Ausstanzen einzelner Blisterverpackungen 2 aus der Blisterbahn. Die einzelnen Blisterverpackungen 2 werden dann weiteren Bearbeitungsmaßnahmen zugeführt.In a subsequent sealing station 30, the cover film 12 is provided and sealed to webs 10 of the base film 6. At the same time, the cover film 12 is also sealed to the strips 14 made of active material. Overall, a sealed blister strip is formed in this way. Finally, individual punching out takes place in a downstream punching station 32 Blister packs 2 from the blister strip. The individual blister packs 2 are then fed to further processing measures.

In Fig. 13 sind ein erstes Formwerkzeug 34 und ein zweites Formwerkzeug 36 skizziert, die in der Formstation 24 zusammenwirken, um die Blisternäpfe 8 in die Bodenfolie 6 zu formen. Die beiden Formwerkzeuge 34, 36 sind zwischen einer geöffneten Position und einer geschlossenen Formposition relativ zueinander bewegbar. Hierzu muss zumindest eines der beiden Formwerkzeuge 34, 36 bewegbar sein, vorzugsweise beide. In der geschlossenen Formposition klemmen die beiden Formwerkzeuge 34, 36 die Bodenfolie 6 zum Formvorgang zwischen sich ein. Am zweiten Formwerkzeug 36 ist eine Druckluftquelle 38 angeschlossen, die für die Ausformung der Blisternäpfe 8 in der festgeklemmten Bodenfolie 6 sorgt.In Fig. 13 a first molding tool 34 and a second molding tool 36 are sketched, which cooperate in the molding station 24 in order to shape the blister cups 8 into the base film 6. The two molding tools 34, 36 are movable relative to one another between an open position and a closed molding position. For this purpose, at least one of the two forming tools 34, 36 must be movable, preferably both. In the closed molding position, the two molding tools 34, 36 clamp the base film 6 between them for the molding process. A compressed air source 38 is connected to the second molding tool 36 and ensures that the blister cups 8 are formed in the firmly clamped base film 6.

Das erste Formwerkzeug 34 umfasst mindestens eine, vorzugsweise eine Mehrzahl von Mulden 40 zur Bildung mindestens eines Blisternapfes 8 in der Bodenfolie 6. Die mindestens eine Mulde 40 weist eine mindestens zweistufige Form auf. Eine erste Ausnehmung 42 der Mulde 40 definiert eine erste Stufe der Mulde 40. Eine zweite Ausnehmung 44 der Mulde 40 ist in einem Teilabschnitt eines von der ersten Ausnehmung 42 überspannten Flächenbereichs angeordnet und liegt tiefer als die erste Ausnehmung 42. Die Form der Mulde 40 entspricht der Form der zu bildenden Blisternäpfe 8. Die in Fig. 14 dargestellte Form der Mulde 40 entspricht beispielsweise der Form der Blisternäpfe 8 der Blisterverpackung 2 aus Fig. 1 bis 3.The first molding tool 34 comprises at least one, preferably a plurality of troughs 40 for forming at least one blister cup 8 in the bottom foil 6. The at least one trough 40 has an at least two-stage shape. A first recess 42 of the trough 40 defines a first step of the trough 40. A second recess 44 of the trough 40 is arranged in a section of a surface area spanned by the first recess 42 and is lower than the first recess 42. The shape of the trough 40 corresponds the shape of the blister cups to be formed 8. The in Fig. 14 The shape of the depression 40 shown corresponds, for example, to the shape of the blister cups 8 of the blister pack 2 from Figs. 1 to 3 .

In Fig. 15 und 16 sind ein erstes Siegelwerkzeug 54 und ein zweites Siegelwerkzeug 56 skizziert, die in der Siegelstation 30 zusammenwirken, um die Deckfolie 12 an die Stege 10 der Bodenfolie 6 und an die Streifen 14 aus Aktivmaterial zu siegeln. Die beiden Siegelwerkzeuge 54, 56 sind zwischen einer geöffneten Position (Fig. 15) und einer geschlossenen Siegelposition (Fig. 16) relativ zueinander bewegbar. Hierzu muss zumindest eines der beiden Siegelwerkzeuge 54, 56 bewegbar sein, vorzugsweise beide. In der geschlossenen Siegelposition pressen die beiden Siegelwerkzeuge 54, 56 die Deckfolie 12 an die Stege 10 der Bodenfolie 6 und an die Streifen 14 aus Aktivmaterial. Das zweite Siegelwerkzeug 56 weist mindestens ein Heizmittel 58 auf. Das erste Siegelwerkzeug 54 kann ein Kühlmittel (nicht dargestellt) aufweisen.In Fig. 15 and 16 a first sealing tool 54 and a second sealing tool 56 are sketched, which cooperate in the sealing station 30 in order to seal the cover sheet 12 to the webs 10 of the base sheet 6 and to the strips 14 of active material. The two sealing tools 54, 56 are between an open position ( Fig. 15 ) and a closed seal position ( Fig. 16 ) movable relative to each other. For this purpose, at least one of the two sealing tools 54, 56 must be movable, preferably both. In the closed sealing position, the two sealing tools 54, 56 press the cover film 12 against the webs 10 of the base film 6 and against the strips 14 made of active material. The second sealing tool 56 has at least one heating means 58. The first sealing tool 54 can have a coolant (not shown).

Das erste Siegelwerkzeug 34 umfasst mindestens eine, vorzugsweise eine Mehrzahl von Mulden 60 zur Aufnahme mindestens eines Blisternapfes 8 der Bodenfolie 6. Die mindestens eine Mulde 60 weist eine mindestens zweistufige Form auf. Eine erste Ausnehmung 62 der Mulde 60 definiert eine erste Stufe der Mulde 60. Eine zweite Ausnehmung 64 der Mulde 60 ist in einem Teilabschnitt eines von der ersten Ausnehmung 62 überspannten Flächenbereichs angeordnet und liegt tiefer als die erste Ausnehmung 62. Die Form der Mulde 60 entspricht im Wesentlichen der Form der zuvor in der Formstation 24 gebildeten Blisternäpfe 8. Im konkreten Beispiel entspricht die Form der Mulde 60 der Blisterverpackung aus Fig. 1 bis 3.The first sealing tool 34 comprises at least one, preferably a plurality of troughs 60 for receiving at least one blister cup 8 of the base film 6. The at least one trough 60 has an at least two-step shape. A first recess 62 of the trough 60 defines a first step of the trough 60. A second recess 64 of the trough 60 is arranged in a section of a surface area spanned by the first recess 62 and is lower than the first recess 62. The shape of the trough 60 corresponds essentially the shape of the blister cups 8 previously formed in the forming station 24. In the specific example, the shape of the trough 60 corresponds to the blister pack Figs. 1 to 3 .

Beim Ablegen der Streifen 14 aus Aktivmaterial auf der mindestens einen Auflagefläche 20 der ersten Ausnehmung 16 ist es vorteilhaft, dass die Streifen 14 aus Aktivmaterial um 0,05 mm bis 0,5 mm, mehr bevorzugt um 0,08 mm bis 0,2 mm über die Stege 10 der Bodenfolie nach oben vorstehen. Die Geometrie der Blisternäpfe 8 sowie der ersten Ausnehmung 62 im ersten Siegelwerkzeug 54 ist dementsprechend auf die Dicke des Streifens 14 aus Aktivmaterial anzupassen, so dass dieser Überstand vor dem Siegelvorgang in der Siegelstation 30 vorliegt. Durch diesen Überstand der Streifen 14 wird sichergestellt, dass die Deckfolie 12 nicht nur an die Stege 10 der Bodenfolie 6 gesiegelt wird, sondern auch an die Streifen 14 aus Aktivmaterial.When placing the strips 14 made of active material on the at least one support surface 20 of the first recess 16, it is advantageous that the strips 14 made of active material by 0.05 mm to 0.5 mm, more preferably by 0.08 mm to 0.2 mm protrude upward over the webs 10 of the bottom sheet. The geometry of the blister cups 8 and of the first recess 62 in the first sealing tool 54 must accordingly be adapted to the thickness of the strip 14 of active material, so that this protrusion is present in the sealing station 30 before the sealing process. This protrusion of the strips 14 ensures that the cover film 12 is not only sealed to the webs 10 of the base film 6, but also to the strips 14 made of active material.

In Fig. 17 bis 19 ist eine weitere Ausführungsform der erfindungsgemäßen Blisterverpackung 2 dargestellt. Diese Ausführungsform entspricht in wesentlichen Teilen der Ausführungsform aus Fig. 1 bis 3. Fig. 17 entspricht hierbei der Darstellung aus Fig. 1, Fig. 18 entspricht der Darstellung aus Fig. 2 und Fig. 19 entspricht der Darstellung aus Fig. 3. Insofern ist für die vorliegende Ausführungsform die Beschreibung zu Fig. 1 bis 3 einschlägig, sofern nicht anders angegeben. Identische Elemente sind mit identischen Bezugszeichen versehen.In Figures 17 to 19 a further embodiment of the blister pack 2 according to the invention is shown. This embodiment corresponds in essential parts to the embodiment from FIG Figs. 1 to 3 . Fig. 17 corresponds to the illustration from Fig. 1 , Fig. 18 corresponds to the illustration from Fig. 2 and Fig. 19 corresponds to the illustration from Fig. 3 . In this respect, the description is for the present embodiment Figs. 1 to 3 relevant unless otherwise stated. Identical elements are provided with identical reference symbols.

Abweichend von der Ausführungsform aus Fig. 1 bis 3 sind die Auflageflächen 20 für den Streifen 14 aus Aktivmaterial durch zwei nach oben abragende Noppen 50 in der Bodenfolie 6 im Bereich der ersten Ausnehmung 16 gebildet. Die beiden Noppen 50 sind lediglich in der Querschnittsansicht gemäß Fig. 19 zu erkennen, weil sie in den anderen beiden Ansichten durch den Streifen 14 überdeckt sind.Deviating from the embodiment Figs. 1 to 3 the bearing surfaces 20 for the strip 14 made of active material are formed by two upwardly protruding knobs 50 in the base film 6 in the area of the first recess 16. The two knobs 50 are only shown in the cross-sectional view according to FIG Fig. 19 can be seen because they are covered by the strip 14 in the other two views.

In Fig. 26 und 27 ist eine weitere mögliche Ausgestaltung der Formwerkzeuge 34, 36 dargestellt. Diese Ausgestaltung entspricht in wesentlichen Teilen der Ausführungsform aus Fig. 13 und 14. Fig. 26 entspricht hierbei der Darstellung aus Fig. 13 und Fig. 27 entspricht der Darstellung aus Fig. 14. Insofern ist für die vorliegende Ausgestaltung die Beschreibung zu Fig. 13 und 14 einschlägig, sofern nicht anders angegeben. Identische Elemente sind mit identischen Bezugszeichen versehen.In Fig. 26 and 27 a further possible embodiment of the forming tools 34, 36 is shown. This configuration corresponds in essential parts to the embodiment from FIG Fig. 13 and 14th . Fig. 26 corresponds to the illustration from Fig. 13 and Fig. 27 corresponds to the illustration from Fig. 14 . In this respect, the description for the present embodiment is too Fig. 13 and 14th relevant unless otherwise stated. Identical elements are provided with identical reference symbols.

Abweichend von der Ausführungsform aus Fig. 13 und 14 umfasst das erste Formwerkzeug 34 im Bereich der ersten Ausnehmung 42 der Mulde 40 zwei abragende Vorsprünge 46, die neben der zweiten Ausnehmung 44 angeordnet sind. Dadurch werden beim Formen der Blisternäpfe 8 in die Bodenfolie 6 zwei nach oben abragende Noppen 50 in die Bodenfolie 6 eingeformt, die die Auflageflächen für die Streifen 14 aus Aktivmaterial bilden. In Fig. 27 sind die beiden Vorsprünge 46 nochmals in Draufsicht erkennbar. Mit dem hier dargestellten Formwerkzeug 34 wird die Blisterverpackung 2 aus Fig. 1 bis 3 geformt.Deviating from the embodiment Fig. 13 and 14th In the area of the first recess 42 of the trough 40, the first molding tool 34 comprises two protruding projections 46 which are arranged next to the second recess 44. As a result, when the blister cups 8 are formed in the base film 6, two upwardly protruding knobs 50 are formed in the base film 6, which form the contact surfaces for the strips 14 made of active material. In Fig. 27 the two projections 46 can be seen again in plan view. With the molding tool 34 shown here, the blister pack 2 is made from Figs. 1 to 3 shaped.

In Fig. 28 und 29 ist eine weitere mögliche Ausgestaltung der Siegelwerkzeuge 54, 56 dargestellt. Diese Ausgestaltung entspricht in wesentlichen Teilen der Ausführungsform aus Fig. 15 und 16. Fig. 28 entspricht hierbei der Darstellung aus Fig. 15 und Fig. 29 entspricht der Darstellung aus Fig. 16. Insofern ist für die vorliegende Ausgestaltung die Beschreibung zu Fig. 15 und 16 einschlägig, sofern nicht anders angegeben. Identische Elemente sind mit identischen Bezugszeichen versehen.In Fig. 28 and 29 a further possible embodiment of the sealing tools 54, 56 is shown. This configuration corresponds in essential parts to the embodiment from FIG Fig. 15 and 16 . Fig. 28 corresponds to the illustration from Fig. 15 and Fig. 29 corresponds to the illustration from Fig. 16 . In this respect, the description for the present embodiment is too Fig. 15 and 16 relevant unless otherwise stated. Identical elements are provided with identical reference symbols.

In Abwandlung zu den Siegelwerkzeugen aus Fig. 15 und 16 weist das erste Siegelwerkzeug 54 hier zwei nach oben abragende Vorsprünge 66 auf, die der Form der in die Bodenfolie 6 geformten Noppen 50 entsprechen und an einer solchen Stelle angeordnet sind, dass die Noppen 50 während des Siegelprozesses auf den Vorsprüngen 66 zu liegen kommen. Die Vorsprünge 66 dienen zur Stützung der Noppen 50 der Bodenfolie 6 während des Siegelvorgangs.As a modification of the sealing tools Fig. 15 and 16 the first sealing tool 54 here has two upwardly protruding projections 66 which correspond to the shape of the knobs 50 formed in the base film 6 and are arranged at such a point that the knobs 50 come to rest on the projections 66 during the sealing process. The projections 66 serve to support the knobs 50 of the base film 6 during the sealing process.

Die in Fig. 30 und 31 dargestellten Siegelwerkzeuge 54, 56 entsprechen im Wesentlichen den in Fig. 28 und 29 dargestellten Siegelwerkzeugen 54, 56. Identische Elemente sind mit identischen Bezugszeichen versehen. In Abwandlung zur Ausführungsform der Fig. 28 und 29 sind die Vorsprünge 66 im ersten Siegelwerkzeug 54 durch Stifte 68 ersetzt, die nach oben über den Bodenbereich der ersten Ausnehmung 62 der Mulde 60 vorragen. Die Stifte 68 dienen zur Stützung der Noppen 50 der Bodenfolie 6 während des Siegelvorgangs. Die Stifte 68 können wie dargestellt federgelagert sein. Die Stifte 68 können ausfahrbar im ersten Siegelwerkzeug 54 angeordnet sein.In the Fig. 30 and 31 The sealing tools 54, 56 shown essentially correspond to those in FIG Fig. 28 and 29 sealing tools 54, 56 shown. Identical elements are provided with identical reference numerals. As a modification of the embodiment of the Fig. 28 and 29 the projections 66 in the first sealing tool 54 are replaced by pins 68 which protrude upwards over the bottom region of the first recess 62 of the trough 60. The pencils 68 serve to support the knobs 50 of the base film 6 during the sealing process. The pins 68 can be spring loaded as shown. The pins 68 can be arranged in the first sealing tool 54 such that they can be extended.

Die Noppen 50 in der Bodenfolie 6 weisen vorzugsweise eine Höhe von zwischen 0,5 mm und 5 mm, bevorzugt zwischen 1 mm und 3 mm auf. Dementsprechend weisen auch die Vorsprünge 46 im ersten Formwerkzeug 34 und gegebenenfalls die Vorsprünge 66 im ersten Siegelwerkzeug 54 eine Höhe von zwischen 0,5 mm und 5 mm, bevorzugt zwischen 1 mm und 3 mm auf. Wenn Stifte 68 verwendet werden, stehen diese vorzugsweise über eine Höhe von zwischen 0,5 mm und 5 mm, bevorzugt zwischen 1 mm und 3 mm, über den Bodenbereich der ersten Ausnehmung 62 der Mulde 60 vor oder sind bis dahin ausgefahren.The knobs 50 in the base film 6 preferably have a height of between 0.5 mm and 5 mm, preferably between 1 mm and 3 mm. Correspondingly, the projections 46 in the first molding tool 34 and optionally the projections 66 in the first sealing tool 54 also have a height of between 0.5 mm and 5 mm, preferably between 1 mm and 3 mm. If pins 68 are used, they preferably protrude over a height of between 0.5 mm and 5 mm, preferably between 1 mm and 3 mm, over the bottom region of the first recess 62 of the trough 60 or have extended by then.

In den dargestellten Ausführungsformen sind die Noppen 50 als abgerundete Erhebungen dargestellt. Ebenso sind andere Formen der Noppen 50 denkbar, beispielsweise Noppen 50 mit einer dreieckigen Querschnittsform mit abgerundeter Spitze oder mit einer ebenen oberen Plateaufläche, auf der der Streifen 14 aus Aktivmaterial aufliegt. Die Noppen 50 können sich auch als längliche Objekte entlang einer Linie (gerade, gekrümmt) erstrecken. Die Form der Vorsprünge 46, 66 und/oder der Spitzen der Stifte 68 entspricht vorzugsweise jeweils der Form der Noppen 50 in der Bodenfolie 6.In the illustrated embodiments, the knobs 50 are shown as rounded elevations. Other shapes of the knobs 50 are also conceivable, for example knobs 50 with a triangular cross-sectional shape with a rounded tip or with a flat upper plateau surface on which the strip 14 of active material rests. The knobs 50 can also extend as elongated objects along a line (straight, curved). The shape of the projections 46, 66 and / or the tips of the pins 68 preferably corresponds in each case to the shape of the knobs 50 in the base film 6.

Es ist auch möglich, anstelle von mehreren Noppen 50 eine umlaufende Rippe auszubilden. Dies ist insbesondere bei der Ausführungsform gemäß Fig. 8 bis 11 denkbar. Fig. 32 zeigt diese Abwandlung in der Querschnittsansicht. Die umlaufende Rippe 70 kann in Draufsicht eine beliebige Ringform aufweisen, z.B. in Form eines Kreisrings, eines ovalen Rings, eines eckigen Rings etc.It is also possible to form a circumferential rib instead of several knobs 50. This is particularly true in the embodiment according to FIG Figs. 8-11 conceivable. Fig. 32 shows this modification in cross-sectional view. The circumferential rib 70 can have any desired ring shape in plan view, for example in the form of a circular ring, an oval ring, an angular ring, etc.

Zur Herstellung von Blisterverpackungen wie in Fig. 32 wird im ersten Formwerkzeug 34 lediglich ein umlaufender Vorsprung 76 in derselben Form wie die Rippe 70 ausgebildet sein. Fig. 33 zeigt eine Querschnittsansicht einer solchen Ausgestaltung.For the production of blister packs as in Fig. 32 In the first mold 34, only a circumferential projection 76 in the same shape as the rib 70 will be formed. Fig. 33 Figure 3 shows a cross-sectional view of such an embodiment.

Ebenso wird vorzugsweise lediglich ein ebenso geformter, umlaufender Vorsprung 86 im ersten Siegelwerkzeug 54 ausgebildet sein, wie aus der Querschnittsansicht aus Fig. 34 hervorgeht.Likewise, only one circumferential projection 86 of the same shape is preferably formed in the first sealing tool 54, as shown in the cross-sectional view from FIG Fig. 34 emerges.

Alternativ könnte im ersten Siegelwerkzeug 54 auch ein umlaufendes, ausfahrbares Stützelement 78 verwendet werden, dessen Scheitel der Form der Rippe 70 entspricht. Fig. 35 zeigt eine solche Gestaltung im Querschnitt. Das Stützelement 78 ist vorzugsweise federgelagert.Alternatively, a circumferential, extendable support element 78 could also be used in the first sealing tool 54, the apex of which corresponds to the shape of the rib 70. Fig. 35 shows such a design in cross section. The support element 78 is preferably spring-loaded.

Für die Querschnittsform der Rippe 70, des Vorsprungs 76, des Vorsprungs 86 oder des Scheitels des Stützelements 78 gilt dann Entsprechendes wie für die Querschnittsform der Noppen 50.For the cross-sectional shape of the rib 70, the protrusion 76, the protrusion 86 or the apex of the support element 78, the same applies as for the cross-sectional shape of the knobs 50.
