Es ist bekannt Bodenteile, auch Warenträger genannt, von Blisterpackungen, auch Durchdrückpackungen genannt, mit durchdrückbaren Abdeckfolien, beispielsweise aus Metall, wie Aluminium, zu verschliessen. Die Abdeckfolie kann eine Aluminiumfolie beschichtet mit einer Siegelschicht, wie einem Siegellack, sein. Die Aluminiumfolie wird über die Siegelschicht auf das Bodenteil gesiegelt. Zur Entnahme der Inhaltsstoffe werden diese durch Verformen der Vertiefung gegen die Abdeckfolie gedrückt, wobei die Abdeckfolie einreisst oder aufplatzt und den Inhaltsstoff bzw. das Füllgut freigibt. Dies bedeutet, dass die Abdeckfolie inelastisch und leicht einreissbar sein muss. So eignen sich beispielsweise mit einer Siegelschicht veredelte Aluminiumfolien für diesen Zweck besonders gut. Die beschriebenen Blisterpackungen enthalten beispielsweise Medikamente als Pillen, Tabletten, Dragees, Ampullen und dergl.It is known base parts, also called product carriers, of blister packs, also push-through packs called, with push-through cover films, for example made of metal, like aluminum. The cover film can be coated with an aluminum film with a sealing layer, like a sealing wax. The aluminum foil is over the sealing layer sealed on the bottom part. The ingredients are removed by Deformation of the depression pressed against the cover film, the cover film tearing or bursts and releases the ingredient or product. This means that the cover film must be inelastic and easily tearable. For example, with aluminum foil is especially well-suited for this purpose. The described Blister packs contain medicines such as pills, tablets, Dragees, ampoules and the like.

Die Inhaltsstoffe, insbesondere Medikamente, in ihren meist bunten und süssigkeitsähnlichen Darreichungsformen erwecken die Neugierde von Kindern. Um den Zugriff auf spezielle Medikamente zu verhindern, ist es sehr oft zweckmässig, die Öffnungshandgriffe zu erschweren. Den genannten Abdeckfolien haftet der Nachteil an, dass durch den beabsichtigten Zweck der leichten Durchstossbarkeit, eine Entnahme der Inhaltsstoffe aus der Verpackung auch für Kinder kein unüberwindbares Hindernis darstellt.The ingredients, especially medicines, in their mostly colorful and candy-like Dosage forms arouse children's curiosity. To access special To prevent medication, it is very often advisable to close the opening handles difficult. The above-mentioned cover films have the disadvantage that the intended Purpose of easy penetration, a removal of the ingredients from the packaging not an insurmountable obstacle for children either.

Aus der DE-A-29 19 713 ist eine kindergesicherte Arzneimittelverpackung aus einer Grundfolie, einer Durchdrückfolie und einer Sicherheitsfolie bekannt. Der Inhaltsstoff kann erst nach vollständigem Entfernen der Sicherheitsfolie, zum Beispiel durch abschälen der Sicherheitsfolie, mittels Durchdrücken aus der Packung entnommen werden, was jedoch auch erwachsenen Personen, insbesondere älteren Personen, Mühe bereiten kann. DE-A-29 19 713 describes a child-resistant pharmaceutical packaging made from a base film, a push-through film and a security film known. The ingredient can only after the safety film has been completely removed, for example by peeling off the safety film, can be removed from the pack by pushing through, but this is also the case adults, especially older people, can cause trouble.

Die Abdeckfolie kann auch Kunststoffe und/oder celluloseartige Materialien, wie Karton oder Papier enthalten. Als Kunststoffe können insbesondere jene, vorstehend für das Bodenteil Beschriebene, verwendet werden. Bei Abdeckfolien aus einem Kunststoff-Metall-Verbund kann die Metallschicht in Form einer Folie vorliegen oder aufgedampft sein.The cover film is expediently not or only difficult to push through by hand. she can for example from an aluminum foil, in particular from one with a sealing layer refined aluminum foil or a composite containing aluminum foil. The cover film can also be plastics and / or cellulosic materials, such as cardboard or paper contain. In particular, those described above for the base part can be used as plastics, be used. For cover foils made of a plastic-metal composite the metal layer can be in the form of a foil or can be vapor-deposited.

Im weiteren können, insbesondere für sortenreine Packungen, auch Abdeckfolien aus Kunststoffen, insbesondere aus Polypropylen, ohne Metallfolien oder -schichten eingesetzt werden, welche mit entsprechenden nachfolgend beschriebenen Öffnungshilfen durchstochen, durchschnitten oder geschwächt werden können. Die Kunststoffe können beispielsweise zur Herabsetzung der Reissfestigkeit und zur Erleichterung der Öffnung Füllstoffe enthalten. Die Abdeckfolie kann auch, z.B. im Bereich der Vertiefungsöffnung, geschwächt sein oder Schwächungslinien aufweisen, wodurch beispielsweise der Öffnungsvorgang unter Anwendung der Öffnungshilfen erleichtert wird. Die Schwächungslinien sind jedoch zweckmässig so ausgebildet, dass sich die Inhaltsstoffe ohne Anwendung der Öffnungshilfen vorteilhaft nicht von Hand durchdrücken lassen. Furthermore, especially for single-variety packs, plastic cover films, especially made of polypropylene, without metal foils or layers, which are pierced with the corresponding opening aids described below, can be cut or weakened. The plastics can for example Reduced tear strength and fillers to facilitate opening. The cover sheet can also, e.g. weakened in the area of the recess or Have lines of weakness, which, for example, the opening process using the opening aids are facilitated. However, the lines of weakness are appropriate designed so that the ingredients are beneficial without using the opening aids do not let it push through by hand.

In einer weiteren Variante kann die vorgenannte Abdeckfolie auf der Kunststofffolie eine weitere Kaschierung mit Papier enthalten.Furthermore, the cover film can also be a heat seal lacquer coated aluminum film Contain thickness of 20-50 microns, in particular 20-30 microns, preferably 20-25 microns which is an external PET (polyethylene terephthalate) film with a thickness of 10 - 30 microns, especially from 12 to 20 microns, is laminated. In a further variant, the aforementioned Cover film on the plastic film contain another lamination with paper.

Die Abdeckfolie überdeckt das Bodenteil beispielsweise teil- oder vollflächig und verschliesst wenigstens die Vertiefungsöffnungen. Sie wird zweckmässig durch Kleben oder Siegeln mit dem Bodenteil verbunden. Die Siegelschichten können beispielsweise Polyolefine, wie Polyethylene, Polypropylene oder Polyester, wie Polyethylenterephthalate oder Polyethylen-2, 6-naphtalat enthalten oder daraus bestehen und in Folien- oder Lackform vorliegen und können beispielsweise eine Dicke im Bereich von 1 bis 50 µm aufweisen. Entsprechend können auch Heisssiegellacke verwendet werden. Als Klebstoffe können beispielsweise Phenolharze, Epoxidharze, Cyanacrylate, Acrylate, modifizierte Acrylate und insbesondere Klebstoffe auf Polyurethan-Basis eingesetzt werden.The cover sheet covers the bottom part, for example, partially or over the entire area and closes at least the recess openings. It is useful by gluing or Sealing connected to the bottom part. The sealing layers can, for example, polyolefins, such as polyethylene, polypropylene or polyester, such as polyethylene terephthalate or Contain or consist of polyethylene-2, 6-naphthalate and in foil or lacquer form are present and can for example have a thickness in the range of 1 to 50 microns. Correspondingly, heat seal lacquers can also be used. As adhesives, for example Phenolic resins, epoxy resins, cyanoacrylates, acrylates, modified acrylates and in particular, adhesives based on polyurethane are used.

Die Abdeckfolie widersteht zweckmässig den üblichen Durchdrückkräften, die zur Entnahme der Inhaltsstoffe aus der Vertiefung angewendet werden müssen, insbesondere jenen Durchdrückkräften die Kinder befähigt sind auszuüben. Der Widerstand der Deckschicht kann sich aus deren Reissfestigkeit und/oder Elastizität ergeben.The cover film expediently withstands the usual push-through forces that are required for removal of the ingredients from the specialization must be used, especially those Push-through powers that children are able to exercise. The resistance of the top layer can result from their tensile strength and / or elasticity.

Die Öffnungshilfen sind oder enthalten vorteilhaft Flächenteile, die zweckmässig aus dem Schulterbereich der Blisterpackung vorstehen oder entlang von Schwächungslinien aus dem Schulterbereich gelöst werden können. Weiters können Faltlinien vorgesehen sein, an denen das Flächenteil umgebogen werden kann. Die Öffnungshilfen bzw. die dazugehörigen Flächenteile weisen vorteilhaft öffnungswirksame Kanten und/oder Spitzen auf, welche auf den zu öffnenden Flächenbereich in der Abdeckfolie gebracht werden können.The opening aids are or advantageously contain areas that are expedient from the Protrude shoulder area of the blister pack or along lines of weakness from the Shoulder area can be solved. Furthermore, folding lines can be provided on which the surface part can be bent. The opening aids and the associated surface parts advantageously have opening-effective edges and / or tips which on the can be brought to the opening surface area in the cover film.

Faltlinien sind zweckmässig derart beschaffen, dass sich an diesen Teile umbiegen lassen ohne vollständig abgetrennt zu werden. Sie sind keine Trennlinien, so dass sich Teile entlang einer Faltlinie nicht oder nur schwer von Hand abtrennen lassen.Fold lines are appropriately designed in such a way that they can be bent over on these parts without being completely separated. They are not dividing lines, so parts are along a fold line is difficult or difficult to remove by hand.

Es kann beispielsweise eine längliche Spitze vorgesehen sein, welche sich entlang von Schwächungslinien, beispielsweise perforierten Linien, aus dem Bodenteil drücken bzw. lösen lässt und soweit umgebogen werden kann, dass ihre Spitze auf den zu öffnenden Flächenbereich der Abdeckfolie stösst. For example, an elongated tip can be provided, which extends along Press lines of weakness, for example perforated lines, out of the base part or can be released and bent so far that its tip on the surface area to be opened of the cover film.

Es kann auch vorgesehen sein, dass sich die Öffnungshilfe vollständig entlang von Schwächungslinien aus dem Bodenteil herauslösen oder -trennen lässt.It can also be provided that the opening aid extends completely along lines of weakness can be loosened or separated from the bottom part.

In einer in dieser Anmeldung nicht beanspruchten weiteren Verpackungslösung kann jeweils neben einer Vertiefung in der Schulterfläche der Blisterpackung ein Flächenstück, zweckmässig ohne Vertiefung, vorgesehen sein. Das Flächenstück ist nicht mit dem vorgenannten Flächenteil als Öffnungshilfe zu verwechseln. Das Flächenstück grenzt sich durch eine oder mehrere Schwächungslinien und wenigstens durch eine Faltlinie vom restlichen Bodenteil derart ab, dass das Flächenstück entlang der Schwächungslinien aus dem Bodenteil getrennt und durch Umklappen entlang der Faltlinie über die benachbarte Vertiefungsöffnung gelegt werden kann. Die Faltlinie ist bevorzugt zwischen dem Flächenstück und der Vertiefung angeordnet.In a further packaging solution not claimed in this application, in each case, in addition to a recess in the shoulder area of the blister pack a piece of space, expediently without a depression, be provided. The area piece is not with the aforementioned area part as an opening aid to be confused. The patch is bordered by one or more lines of weakness and at least by a fold line from the rest of the bottom part such that the patch along the lines of weakness separated from the bottom part and by Fold down along the fold line over the adjacent opening can. The fold line is preferably arranged between the surface piece and the depression.

Das schwenkbare Flächenstück enthält zweckmässig eine Öffnungshilfe, beispielsweise wie vorgängig beschrieben, welche beim Umschwenken des Flächenstückes direkt über die die Vertiefungsöffnung überziehende Abdeckfolie gebracht werden kann, so dass die Öffnungshilfe direkt auf die Abdeckfolie angesetzt werden kann.The pivotable surface piece expediently contains an opening aid, for example how previously described, which when swiveling the patch directly over the Cover film covering recess opening can be brought, so that the opening aid can be attached directly to the cover film.

Die Flächenstücke lassen sich entlang der Faltlinie umbiegen. Die Faltlinie soll insbesondere nach mehrmaligem Falten immer noch eine genügende Verbindung zwischen Flächenstück und der restlichen Blisterpackung gewährleisten. Die Faltlinie ist zweckmässig derart ausgebildet sein, dass sich das Flächenstück in beide Richtungen, also beispielsweise im Uhrzeiger- und Gegenuhrzeigersinn schwenken lässt.The patches can be bent along the fold line. The fold line is intended in particular after repeated folding, there is still a sufficient connection between the patch and the rest of the blister pack. The fold line is expediently designed in this way be that the patch is in both directions, for example clockwise and swings counterclockwise.

Die Vertiefungen einer Blisterpackung können beispielsweise in Kolonnen und Reihen, vorzugsweise in zwei Kolonnen, angeordnet sein. Jeder Kolonne von Vertiefungen ist beispielsweise eine weitere Kolonne von Flächenstücken, enthaltend je eine Öffnungshilfe, zugeordnet. Die Kolonne von Flächenstücken ist vorteilhaft über eine Faltlinie mit der Kolonne der Vertiefungen verbunden. Die einzelnen Flächenstücke sind ansonsten durch Schwächungslinien gegeneinander oder gegen die angrenzenden Schulterbereiche der Vertiefungen abgegrenzt.The depressions of a blister pack can, for example, preferably be in columns and rows be arranged in two columns. Each column of wells is for example another column of patches, each containing an opening aid, assigned. The column of sheets is advantageous over a fold line with the column of the wells connected. The individual patches are otherwise through Lines of weakness against each other or against the adjacent shoulder areas of the depressions demarcated.

Die Vertiefungen einer Blisterpackung können in einer weiteren Ausführungsform gegenseitig versetzt angeordnet sein, wobei die Flächenstücke mit Öffnungshilfen, ebenfalls gegenseitig versetzt, jeweils zwischen wenigstens zwei Vertiefungen angeordnet sind. Dadurch kann die vorhandene Fläche des Bodenteils besser genutzt und Verpackungsmaterial eingespart werden, da die Flächenstücke mit den Öffnungshilfen beispielsweise weniger Platz beanspruchen als die von Schultern umgebenen Vertiefungen.In a further embodiment, the depressions of a blister pack can be mutual be staggered, the patches with opening aids, also mutually offset, are each arranged between at least two depressions. Thereby can make better use of the existing area of the base part and save packaging material because the area pieces with the opening aids, for example, take up less space claim as the recesses surrounded by shoulders.

In einer in dieser Anmeldung nicht beanspruchten weiteren Verpackungslösung ist die Öffnungshilfe in Form von einzelnen oder einer Mehrzahl von Zähnen, vorzugsweise in der Form von Spitzen oder Zakken, ausgebildet.

To open the recess opening, the shoulder area with With the help of the rolling element rolled up from the edge, the cover film when rolling expediently lies on the inside. As soon as the roll-up element covers the area the opening aid starts to roll up, this is due to the resulting bending stresses detached from the shoulder area along the lines of weakness and is preferably tangential from the rolled-up shoulder area. As the shoulder area rolls up the protruding opening aid with the shoulder area around the roll-up element wrapped and hits with its opening-effective edge or tip, preferably vertically, on the cover film, the distances between the opening aid and the recess and between the opening aid and the edge or roll-up element are selected such that the opening-effective edge or tip of the cover film preferably in the edge region of the Penetration opening penetrates at least in sections or weakens it, so that the ingredient can be pushed out of the recess. The weakening of the cover film has the function of a tear notch along which the cover film begins to tear when pressure is applied vertically to the cover film and releases the ingredient. The lines of weakness can be as described above be executed.

Die Durchdrückpackung weist an entsprechenden Stellen an ihrer Aussenseite vorteilhaft Beschriftungen und graphische Elemente auf, welche dem Anwender unter anderem die einzelnen Öffnungsschritte nahelegen.The blister pack advantageously has appropriate locations on its outside Inscriptions and graphic elements, which among other things the individual Suggest opening steps.

Eine erfindungsgemässe Blisterpackung ist herstellbar dadurch, dass aus einer planen Verbundfolie Vertiefungen geformt werden und ein Inhaltsstoff in die Vertiefungen abgefüllt wird und auf die Verbundfolie über die Vertiefungsöffnungen der Vertiefungen eine Abdeckfolie gesiegelt wird und in die Verbundfolie mit Abdeckfolie Faltlinien und/oder Schwächungslinien der Öffnungshilfen angebracht werden und Blisterpackungen mit einer oder mehreren Vertiefungen zugeschnitten werden. A blister pack according to the invention can be produced from a flat composite film Wells are formed and an ingredient is filled into the wells is and a cover film on the composite film over the recess openings of the recesses is sealed and fold lines and / or in the composite film with cover film Lines of weakness of the opening aids are attached and blister packs with a or more wells.

Weiters können bei Blisterpackungen mit mehreren Vertiefungen ebenfalls vor dem Zuschneiden die Faltlinien und/oder Schwächungslinien der Flächenstücke angebracht werden.In addition, blister packs with several wells can also be cut before the fold lines and / or lines of weakness of the patches are attached.

Die Inhaltsstoffe einer Packung nach vorliegender Erfindung können erst nach Ausführung einer geregelten Abfolge von Öffnungshandgriffen entnommen, d.h. durch die Abdeckfolie aus der Vertiefung gedrückt werden. Dies ist für Kinder eine beinahe unlösbare Aufgabe, können diese doch kaum mehrere simultane Bewegungen nacheinander ausführen. Insbesondere das Herausdrücken der Öffnungshilfen aus dem Bodenteil und das Benützen der Öffnungshilfen zum Verletzen der Abdeckfolie wird von den Kindern nicht intuitiv durchgeführt, sondern setzt gewisse Vorkenntnisse oder die Fähigkeit Packungshinweise zu lesen voraus. Für ältere Leute hingegen ist das Öffnen einer solchen Packung recht einfach.The contents of a package according to the present invention can only be carried out after execution taken from a regulated sequence of opening handles, i.e. through the cover film be pressed out of the recess. This is an almost impossible task for children they can hardly make several simultaneous movements in succession. In particular pushing the opening aids out of the bottom part and using the Children do not intuitively perform opening aids to damage the cover film, but requires certain prior knowledge or the ability to read package instructions ahead. For older people, on the other hand, opening such a package is quite easy.
