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.

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.
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
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.
- 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.
