Description

„Blisterverpackung und Verfahren zur Entnahme eines Produkts aus der Blisterverpackung"  "Blister packaging and method of removing a product from the blister package"

The invention relates to a blister pack with a blister hood and a blister card, wherein the blister hood and the blister card enclose a product chamber for receiving a product. In addition, the invention relates to a method for removing a product from the blister pack.

Für jede Geschirrspültablette ist dabei eine For example, EP 0 903 405 A2 discloses such a blister pack for a plurality of products in the form of dishwashing tablets. For each dishwasher tablet is one

Der Rand der Blisterhaube und die Blisterkarte sind dichtend miteinander verbunden, um die Produktkammer von der Umgebung zu trennen. Die Blisterverpackung weist somit eine The edge of the blister cap and the blister card are sealed together to separate the product chamber from the environment. The blister pack thus has one

Gleichzeitig muss aber auch sichergestellt werden, dass ein Konsument des Produkts die Blisterverpackung einfach öffnen lässt. Protective function to protect the product from environmental influences or the environment from the product. At the same time, however, it must also be ensured that a consumer of the product simply allows the blister packaging to be opened.
Bekannt ist eine Blisterverpackung, bei der die Blisterkarte aus einem Karton gebildet ist, der auf einer Seite mit einer siegelfähigen Beschichtung versehen ist. Der Karton stellt dabei A blister pack is known, in which the blister card is formed from a cardboard which is provided on one side with a sealable coating. The cardboard is doing
üblicherweise, aber nicht notwendigerweise das tragende Element der Blisterverpackung dar. Nach Befüllung der Produktkammer mit dem Produkt wird der Rand der Blisterhaube mit dem beschichteten Karton zwecks Verschließen der Produktkammer versiegelt. Das spätere Öffnen der Produktkammer kann durch Abreißen der Blisterhaube erfolgen. Eine andere Möglichkeit besteht darin, das Produkt durch Druck auf die Blisterhaube gegen die Blisterkarte zu drücken, bis diese einreißt. Um ein Einreißen zu vereinfachen oder zu ermöglichen, ist es bekannt, die Blisterkarte im Bereich der Produktkammer mit einer Schwächungslinie beispielsweise in Form einer Perforation zu versehen. Nachteilig ist dabei, dass durch die Perforation die Barrierewirkung der Blisterkarte stark vermindert wird. Zum Beispiel können so Wasserdampf und Sauerstoff in die Produktkammer gelangen. Auch bei einer Blisterverpackung, bei der die Perforation ein Fingerloch im Bereich der Produktkammer begrenzt, das zwecks Entnahme des Produkts einzudrücken ist, ergeben sich aufgrund der Perforation die gleichen Probleme. Usually, but not necessarily, the supporting element of the blister pack. After filling the product chamber with the product, the edge of the blister cap is sealed with the coated carton to close the product chamber. The subsequent opening of the product chamber can be done by tearing off the blister hood. Another possibility is to press the product against the blister card by pressing on the blister cap until it tears. In order to simplify or facilitate tearing, it is known to provide the blister card in the region of the product chamber with a weakening line, for example in the form of a perforation. The disadvantage here is that the barrier effect of the blister card is greatly reduced by the perforation. For example, water vapor and oxygen can enter the product chamber. Even with a blister pack in which the perforation delimits a finger hole in the area of the product chamber which is to be pushed in order to remove the product, the same problems arise due to the perforation.
Anstelle des Kartons kann für die Blisterkarte auch eine Siegelfolie verwendet werden, die zwecks Entnahme des Produkts von dem Rand der Blisterhaube abgezogen wird. Die Barrierewirkung der Siegelfolie ist gegenüber der Lösung des perforierten Karton stark verbessert, doch besteht die Gefahr, dass bei einer Blisterverpackung mit mehreren nebeneinander angeordneten Instead of the carton can be used for the blister card and a sealing film, which is deducted for the removal of the product of the edge of the blister cap. The barrier effect of the sealing film is greatly improved over the solution of the perforated cardboard, but there is a risk that in a blister pack with several juxtaposed
Blisterhauben beim Abziehen der Siegelfolie zum Öffnen einer Produktkammer eine benachbarte Produktkammer versehentlich mitgeöffnet wird. Zudem ist teils ein erheblicher Kraftaufwand notwendig, um die Siegelfolie von der Blisterhaube zu trennen. Blister hoods when removing the sealing film to open a product chamber an adjacent Product chamber is accidentally mitugsöfflich. In addition, a considerable amount of force is sometimes necessary to separate the sealing film from the blister hood.
Im pharmazeutischen Bereich ist eine Blisterverpackung mit mehreren Produktkammern und einer aluminiumbasierten Siegelfolie sehr verbreitet, die sehr gute Barriereeigenschaften und eine sehr geringe Bruch- oder Reißfestigkeit aufweist. Durch Druck auf die Blisterhaube und damit das Produkt wird die Siegelfolie zum Einreißen gebracht. Das Produkt muss dabei eine gewisse Formstabilität aufweisen, da es den Druck von der Blisterhaube auf die Siegelfolie übertragen muss. Aluminiumbasierte Folien sind vergleichsweise teuer und wegen diverser Umweltaspekte umstritten. In the pharmaceutical field, a blister pack with several product compartments and an aluminum-based sealing foil is very widespread, which has very good barrier properties and very low resistance to breakage or tearing. By pressing on the blister hood and thus the product, the sealing film is torn. The product must have a certain dimensional stability, as it must transfer the pressure from the blister cap on the sealing film. Aluminum-based films are comparatively expensive and controversial for various environmental aspects.
Der Erfindung liegt daher die Aufgabe zu Grunde, eine Blisterverpackung bereit zu stellen, die sich ressourcenschonend herstellen lässt, deren Schutzwirkung für das Produkt hoch ist und die sich einfach öffnen lässt. The invention is therefore based on the object to provide a blister, which can be produced in a resource-friendly, the protective effect of the product is high and can be opened easily.

The object underlying the invention is achieved with the feature combination according to claim 1. Preferred embodiments may be taken from the subclaims to claim 1.
Erfindungsgemäß ist vorgesehen, dass der Rand der Blisterhaube mit einer inneren Auflagefläche und mit einer äußeren Auflagefläche auf der Blisterkarte aufliegt, wobei die Schwächungslinie zwischen der inneren Auflagefläche und der äußeren Auflagefläche angeordnet ist. Alternativ kann die Schwächungslinie auch unter der inneren Auflagefläche angeordnet sein. Durch die erfindungsgemäße Anordnung der Schwächungslinie ist eine direkte Verbindung oder eine direkte Nähe zu der Produktkammer nicht gegeben, wie dies im Stand der Technik der Fall ist. Durch die innere Auflagefläche ist die Schwächungslinie von der Produktkammer zumindest räumlich getrennt. Dadurch wird die Barrierewirkung durch die Schwächungslinie nicht oder nur unwesentlich beeinträchtigt. According to the invention it is provided that the edge of the blister cap rests with an inner support surface and with an outer support surface on the blister card, wherein the line of weakness between the inner support surface and the outer support surface is arranged. Alternatively, the weakening line can also be arranged below the inner support surface. The inventive arrangement of the weakening line does not provide a direct connection or a direct proximity to the product chamber, as is the case in the prior art. Due to the inner bearing surface, the weakening line is at least spatially separated from the product chamber. As a result, the barrier effect is not or only slightly affected by the line of weakness.
Bei der Blisterkarte handelt es sich um ein im Wesentlichen flaches Element, dessen sich in einer Ebene erstreckende Ausmaße deutlich größer sind als eine Dicke der Blisterkarte, also wesentlich größer sind als eine Ausdehnung senkrecht zu besagter Ebene. Insbesondere, wird vorgesehen dass die Blisterkarte mindestens im Bereich der äußeren Auflagefläche flach ist. Dadurch wird zum Beispiel vermieden, dass aufeinander liegende Blisterverpackungen sich verkeilen, und es ergibt sich die Möglichkeit eine Blisterverpackung relativ einfach über eine weitere Blisterverpackung zu schieben. Die Blisterkarte muss dabei nicht zwangsläufig steif oder starr ausgestaltet sein. Auch kann sich die Blisterkarte in einer gekrümmten Ebene erstrecken. Die erfindungsgemäße Blisterverpackung ist eine Durchdrückpackung, in der das Produkt durch ein manuelles Eindrücken der Blisterhaube und ein Durchdrücken durch die Blisterkarte entnommen werden kann. The blister card is a substantially flat element, the dimensions of which extend in one plane being significantly greater than a thickness of the blister card, that is to say substantially larger than an extent perpendicular to said plane. In particular, it is provided that the blister card is flat at least in the region of the outer support surface. As a result, it is avoided, for example, that superimposed blister packs become wedged, and it is possible to relatively easily push a blister pack over another blister pack. The blister card does not necessarily have to be stiff or rigid. Also, the blister card may extend in a curved plane. The blister pack according to the invention is a blister pack, in which the product can be removed by manually pressing the blister hood and pushing through the blister card.
Im Folgenden wird bei der Blisterverpackung der Einfachheit halber auf die Angaben oben, unten, seitlich und sich daraus ergebender Angaben (wie Oberseite, Unterseite) Bezug genommen. Die Blisterkarte soll sich dabei in einer horizontalen Ebene erstrecken. Die Blisterhaube liegt dabei mit ihrem Rand auf einer Oberseite der Blisterkarte auf. Die Produktkammer befindet sich somit oberhalb der Blisterkarte und wird von oben durch die Blisterhaube begrenzt. For the sake of simplicity, the information on top, bottom, side and resulting information (such as top side, underside) is referred to below in the blister packaging. The blister card should extend in a horizontal plane. The blister cap rests with its edge on an upper side of the blister card. The product chamber is thus located above the blister card and is bounded from above by the blister hood.
Die erfindungsgemäße Anordnung oder Reihenfolge in der ersten Variante (innere Auflagefläche, Schwächungslinie und dann die äußere Auflagefläche) bezieht sich auf die seitliche Richtung. In der anderen Variante liegt entsprechend die Schwächungslinie unterhalb der inneren The arrangement or sequence according to the invention in the first variant (inner bearing surface, weakening line and then the outer bearing surface) refers to the lateral direction. In the other variant is correspondingly the line of weakness below the inner
Auflagefläche. Die Begriffe„innere" und„äußere" Auflagefläche beziehen sich auf die Supporting surface. The terms "inner" and "outer" contact surface refer to the
Produktkammer. Somit liegt die innere Auflagefläche immer näher zur Produktkammer als die äußere Auflagefläche. Product chamber. Thus, the inner bearing surface is always closer to the product chamber than the outer bearing surface.
Beispielsweise kann die Blisterkarte rechteckig sein (was abgerundete Ecken des Rechtecks grundsätzlich einschließen soll). Eine Länge der Blisterkarte und eine Breite der Blisterkarte sind in einem Ausführungsbeispiel mindestens um den Faktor 20 oder 40 größer als die Materialstärke der Blisterkarte. Beispielsweise ist die Dicke oder Materialstärke der Blisterkarte kleiner als 2,5 mm, vorzugsweise kleiner als 0,7 mm. For example, the blister card may be rectangular (which should basically include rounded corners of the rectangle). A length of the blister card and a width of the blister card are in one embodiment at least a factor of 20 or 40 greater than the material thickness of the blister card. For example, the thickness or material thickness of the blister card is less than 2.5 mm, preferably less than 0.7 mm.
In einem Ausführungsbeispiel sind Dichtmittel und/oder Haltemittel (im Folgenden vereinfachend zusammengefasst: Dichtmittel), durch die der Rand der Blisterhaube mit der Blisterkarte verbunden ist, ausschließlich an der äußeren Auflagefläche vorgesehen. Die Auflage der inneren In one exemplary embodiment, sealing means and / or holding means (in the following summarized for simplicity: sealing means), by means of which the edge of the blister cap is connected to the blister card, are provided exclusively on the outer bearing surface. The edition of the inner
Auflagefläche auf der Blisterkarte ist somit frei von Dichtmitteln. Bei den Dichtmitteln kann es sich beispielsweise um einen Klebstoffstreifen (Klebstoffraupe) handeln, der auf die Blisterkarte aufgetragen wird. Der Klebstoffstreifen befindet sich dann bei fertiggestellter Blisterverpackung zwischen der Blisterkarte und der äußeren Auflagefläche des Rands der Blisterhaube. In diesem Fall würde die äußere Auflagefläche nicht unmittelbar, sondern mittelbar über den Klebstoffstreifen auf der Blisterkarte aufliegen. Support surface on the blister card is thus free of sealants. The sealants may be, for example, an adhesive strip (adhesive bead) which is applied to the blister card. The adhesive strip is then in finished blister pack between the blister card and the outer bearing surface of the edge of the blister hood. In this case, the outer bearing surface would not rest directly but indirectly over the adhesive strip on the blister card.
Die Dichtmittel müssen nicht notwendigerweise ein zusätzliches Material (wie im obigen Beispiel den Klebstoffstreifen) umfassen. Es ist auch möglich, dass die Dichtmittel durch Wärme oder Druck aus den Materialen von Blisterkarte (einschließlich etwaiger Beschichtungen wie zum Beispiel Siegellack) und Blisterhaube erzeugt werden. Ein Beispiel dafür ist die thermische Versiegelung der Blisterhaube mit der Blisterkarte ohne zusätzlichen Materialeintrag. Dadurch, dass bevorzugt die innere Auflagefläche ohne Dichtmittel auf der Blisterkarte aufliegt, muss keine direkte Haltekraft zwischen Auflagefläche und Blisterkarte überwunden werden, um die Blisterkarte von dem Rand der Blisterhaube zu trennen. Ein Trennen von Blisterkarte und The sealants need not necessarily comprise an additional material (such as the adhesive strip in the above example). It is also possible that the sealants are produced by heat or pressure from the materials of the blister card (including any coatings such as sealing wax) and blister cap. An example of this is the thermal sealing of the blister hood with the blister card without additional material input. Due to the fact that preferably the inner bearing surface without sealing means rests on the blister card, no direct holding force between the bearing surface and blister card must be overcome in order to separate the blister card from the edge of the blister cap. A separation of blister card and
Blisterhaube, sieht man von der Verbindung zwischen äußerer Auflagefläche und Blisterkarte einmal ab und bezieht sich nur die innere Auflagefläche, kann so mit deutlich reduziertem Blister hood, one sees from the connection between the outer support surface and blister card once and refers only to the inner support surface, so can with significantly reduced
Kraftaufwand erfolgen, da die notwendige Kraft zur Entnahme des Produkts (Durchdrücken des Produkts) vollständig in die Verformung der Blisterhaube und in das Aufbrechen der Force, as the necessary force to remove the product (pushing the product) completely in the deformation of the blister hood and in breaking up the
Schwächungslinie fließ kann. Line of weakness can flow.
Die äußere Auflagefläche und die innere Auflagefläche des Rands der Blisterhaube können in verschiedenen Ebenen liegen. Beispielsweise kann so ein kleiner Höhenunterschied ausgeglichen werden, der durch das Vorsehen des Klebstoffstreifens bedingt ist, um die äußere Auflagefläche mit der Blisterkarte zu verkleben. So kann die Ebene, in der die äußere Auflagefläche liegt, etwas weiter von der Ebene der Blisterkarte entfernt sein als die Ebene der inneren Auflagefläche. Die äußere Auflagefläche ist somit gegenüber der inneren Auflagefläche leicht erhöht. Dabei wird es bevorzugt, dass die Blisterkarte im Wesentlichen flach ist. Auch vorgesehen, aber weniger bevorzugt, ist dass, wie auch die Ebene der Blisterkarte, auch die Ebenen der Auflageflächen gewölbt oder gekrümmt sein können und sich der Blisterkarte entsprechend anpassen. The outer bearing surface and the inner bearing surface of the edge of the blister hood can lie in different planes. For example, such a small height difference can be compensated, which is due to the provision of the adhesive strip, to glue the outer bearing surface with the blister card. Thus, the plane in which the outer bearing surface is located may be slightly further away from the plane of the blister card than the plane of the inner bearing surface. The outer bearing surface is thus slightly increased relative to the inner bearing surface. It is preferred that the blister card is substantially flat. Also provided, but less preferred, is that, like the plane of the blister card, the planes of the support surfaces may also be curved or curved and conform to the blister card accordingly.
In einem Ausführungsbeispiel ist eine Vorspannung gegeben, die die innere Auflagefläche gegen die Blisterkarte drückt. Somit liegt eine Pressung zwischen der inneren Auflagefläche und der Blisterkarte vor. Besagte Vorspannung oder besagte Pressung kann beispielsweise dadurch erzeugt werden, dass der Höhenunterschied von innerer Auflagefläche und äußere Auflagefläche so bemessen wird, dass bei der festen Verbindung von Blisterkarte und äußerer Auflagefläche die innere Auflagefläche mehr oder weniger in das Material der Blisterkarte eingedrückt wird. Dadurch entsteht eine gute Barriere zwischen Produktkammer und der Schwächungslinie. Geht man bei der inneren Auflagefläche von einer Linie bzw. einem längsgestreckten Streifen aus, so kann die Vorspannung 1 bis 10 N (2 bis 8 N) pro cm in Längsrichtung betragen. Zudem wird das Aufdrücken erleichtert, da die Kraft beim Druck auf die Blisterhaube besser über die (nicht haftende) innere Auflagefläche auf die Blisterkarte übertragen wird. In one embodiment, a bias is given which presses the inner bearing surface against the blister card. Thus, there is a pressure between the inner support surface and the blister card. Said bias or said pressure can be generated, for example, that the height difference of the inner support surface and outer support surface is dimensioned so that the inner contact surface is more or less pressed into the material of the blister card in the fixed connection of blister card and outer support surface. This creates a good barrier between the product chamber and the weakening line. Assuming the inner bearing surface of a line or an elongated strip, the bias can be 1 to 10 N (2 to 8 N) per cm in the longitudinal direction. In addition, the pressing is facilitated, since the force is better transmitted to the blister on the (non-adhesive) inner bearing surface on the blister card when printing on the blister.
Die innere Auflagefläche und die äußere Auflagefläche können voneinander beanstandet sein, sodass sich ein Hohlraum zwischen den Auflageflächen ergibt. Der Hohlraum wird somit seitlich begrenzt durch die Auflageflächen, nach unten durch die Blisterkarte und nach oben durch die Blisterhaube, deren Rand im Bereich zwischen innerer und äußerer Auflagefläche nicht auf der Blisterkarte aufliegt. Es ist aber auch möglich, dass die innere Auflagefläche und die äußere Auflagefläche ohne Abstand direkt nebeneinander liegen. So könnte die äußere Auflagefläche als der Bereich des Rands der Blisterhaube angesehen werden, der mit der Blisterkarte beispielsweise versiegelt ist. Der nicht versiegelte Bereich des auf der Blisterkarte aufliegenden Rands der Blisterhaube entspricht dann der inneren Auflagefläche, wobei dann gemäß einer Variante der Erfindung unter dieser inneren Auflagefläche die Schwächungslinie angeordnet wäre. The inner bearing surface and the outer bearing surface may be spaced apart from each other, so that there is a cavity between the bearing surfaces. The cavity is thus bounded laterally by the support surfaces, down through the blister card and up through the blister hood, the edge does not rest on the blister card in the area between the inner and outer bearing surface. But it is also possible that the inner bearing surface and the outer bearing surface are located directly next to each other without a gap. Thus, the outer bearing surface could be considered as the region of the edge of the blister cap sealed to the blister card, for example. The unsealed area of the rim of the blister card Blister cap then corresponds to the inner bearing surface, then according to a variant of the invention, the weakening line would be arranged under this inner bearing surface.
In einem Ausführungsbeispiel läuft die innere Auflagefläche vollständig um die Produktkammer herum. Weist beispielsweise in der Draufsicht die Produktkammer einen kreisrunden Querschnitt auf, bildet die innere Auflagefläche einen vorzugsweise konzentrischen Kreis, dessen In one embodiment, the inner support surface runs completely around the product chamber. If, for example, the product chamber has a circular cross section in plan view, the inner bearing surface forms a preferably concentric circle whose
Durchmesser größer ist als der Durchmesser der kreisrunden Produktkammer. Auch die äußere Auflagefläche kann vollständig um die Produktkammer umlaufen, um somit mit den vorzusehenden Dichtmitteln die Produktkammer vollständig zu verschließen. Der Kreis der äußeren Auflagefläche ist dabei im Durchmesser größer als der Kreis der inneren Auflagefläche. Diameter larger than the diameter of the circular product chamber. Also, the outer bearing surface can completely rotate around the product chamber, so as to completely close the product chamber with the sealing means to be provided. The circle of the outer bearing surface is larger in diameter than the circle of the inner bearing surface.
In einem weiteren Ausführungsbeispiel ist die innere Auflagefläche nicht vollständig frei von Dichtmitteln. Die Dichtmittel sind dabei nur punktuell oder bereichsweise vorgesehen. Zwar ergibt sich dadurch eine bei der Entnahme des Produkts zu überwindende gewisse Haltekraft zwischen innerer Auflagefläche und Blisterkarte, doch kann durch diese Maßnahme die Barrierewirkung zwischen innerer Auflagefläche und Blisterkarte eingestellt werden. In a further embodiment, the inner support surface is not completely free of sealants. The sealants are only selectively or partially provided. Although this results in a certain holding force between inner bearing surface and blister card to be overcome when removing the product, the barrier effect between the inner bearing surface and blister card can be adjusted by this measure.
Die innere Auflagefläche kann, in Abhängigkeit der Form der Blisterhaube bzw. der The inner bearing surface can, depending on the shape of the blister hood or the
Produktkammer, jede beliebige Form aufweisen (rechteckig, wobei abgerundete Kanten mit umfasst sein sollen, mehreckig, elliptisch usw.). Die Breite der inneren Auflagefläche quer zur Längserstreckung der Auflagefläche kann in Längsrichtung variieren. Auch die äußere Product chamber, have any shape (rectangular, rounded edges are to be included, polygonal, elliptical, etc.). The width of the inner support surface transversely to the longitudinal extent of the support surface may vary in the longitudinal direction. Also the outer one
Auflagefläche kann entsprechend ausgebildet sein. Support surface can be designed accordingly.
Die Schwächungslinie kann eine umlaufende Linie sein, beispielsweise ein Kreis, mehreckig oder eine Ellipse. Sie kann aber auch lediglich nur eine Gerade, ein Bogen mit Start- und Endpunkt, oder ein Winkel sein, der aus zwei Linien besteht, die eine gemeinsame Ecke bilden. The weakening line may be a circumferential line, for example a circle, polygonal or an ellipse. But it can also be just a straight line, an arc with start and end point, or an angle, which consists of two lines that form a common corner.
Beispielsweise kann die Schwächungslinie als Perforationslinie ausgebildet sein. Dabei kann die Perforationslinie Materialaussparungen aufweisen, die sich nur über einen Teil der Materialdicke der Blisterkarte erstrecken. Beispielsweise ist es möglich, dass die Materialaussparungen sich von einer Unterseite der Blisterkarte nach oben bis etwa zur Mitte der Blisterkarte erstrecken. Alternativ oder zusätzlich ist es möglich, dass die Materialaussparungen von der Oberseite der Blisterkarte ansetzen und sich dann nach unten in das Material der Blisterkarte erstrecken. Die For example, the weakening line may be formed as a perforation line. The perforation line may have material recesses which extend over only a part of the material thickness of the blister card. For example, it is possible that the material recesses extend from an underside of the blister card up to about the middle of the blister card. Alternatively or additionally, it is possible that the material recesses attach from the top of the blister card and then extend down into the material of the blister card. The
Materialaussparungen können somit 100 % der Materialdicke der Blisterkarte oder beispielsweise nur 20 bis 80 % oder 30 bis 70 % erfassen. Zusätzlich oder alternativ kann das Material angestanzt oder geritzt sein, wodurch keine Aussparung, aber eine Schwächung entsteht (Dünnstelle). Material recesses can thus cover 100% of the material thickness of the blister card or, for example, only 20 to 80% or 30 to 70%. Additionally or alternatively, the material may be punched or scratched, whereby no recess, but a weakening arises (thin spot).
Die Blisterkarte kann ein Trägermaterial aus Faserstoff umfassen, der an einer der Blisterhaube zugewandten Seite (Oberseite) mit einem Siegelmedium versehen sein kann. Das Siegelmedium kann beispielsweise ein Siegellack oder eine Kunststofffolie sein, die auf den Faserstoff wie beispielsweise Karton aufkaschiert ist. The blister card can comprise a fibrous carrier material which can be provided with a sealing medium on a side (upper side) facing the blister hood. The sealing medium For example, it may be a sealing wax or a plastic film laminated to the fibrous material such as paperboard.
Die Blisterverpackung kann eine einzige Produktkammer oder mehrere, nebeneinander angeordnete Produktkammern aufweisen. Bei der Mehrkammerlösung kann ein Rand der Blisterhaube einer ersten Produktkammer einstückig in den Rand der Blisterhaube einer zweiten, zur ersten benachbarten Produktkammer übergehen. In diesem Ausführungsbeispiel kann der Verbund der Blisterhauben auch eine tragende Funktion übernehmen. In einem The blister pack may have a single product chamber or a plurality of product chambers arranged side by side. In the multi-chamber solution, one edge of the blister hood of a first product chamber can merge integrally into the edge of the blister hood of a second, adjacent to the first product chamber. In this embodiment, the composite blister hoods can also assume a supporting function. In one
Ausführungsbeispiel sind die Blisterhauben benachbarte Produktkammern voneinander getrennt. Embodiment, the blister covers adjacent product chambers are separated.
Eine weitere Aufgabe der Erfindung, die Bereitstellung eines einfach durchzuführenden Verfahrens zur Entnahme eines Produkts aus einer Blisterverpackung gemäß der obigen Ausführungen, wird durch die Merkmalskombination gemäß Anspruch 1 1 gelöst. Erfindungsgemäß ist vorgesehen, dass bei Verwendung einer Blisterverpackung gemäß der obigen Beschreibung zumindest ein Teil einer Druckkraft, welche auf die Blisterhaube wirkt, im Wesentlichen senkrecht zur Blisterkarte gerichtet ist und dazu führt, dass die Blisterkarte an der Schwächungslinie reißt, über die innere Auflagefläche auf die Blisterkarte geleitet wird. Somit wird Druck über die innere Auflagefläche auf die Blisterkarte ausgeübt und zwar in einem Bereich, der bezogen auf die Schwächungslinie auf der Seite der Produktkammer liegt. Damit ist der Anteil der Druckkraft, der von der Blisterhaube auf das Produkt wirkt, das dann gegen die Blisterkarte drückt, entsprechend kleiner ausgebildet. Dies eröffnet die Möglichkeit, das Produkt, das vorzugsweise eine Waschmaschinentablette oder Geschirrspültablette ist, vielfältiger zu gestalten, da es weniger Druck aushalten muss. Another object of the invention, the provision of a simple method for removing a product from a blister pack according to the above statements, is achieved by the feature combination according to claim 11. According to the invention, when using a blister pack according to the above description, at least part of a compressive force acting on the blister hood is directed substantially perpendicular to the blister card and causes the blister card to tear at the line of weakness over the inner contact surface on the blister card Blister card is headed. Thus, pressure is applied to the blister card via the inner support surface in an area that is located on the side of the product chamber relative to the line of weakness. Thus, the proportion of the compressive force acting on the product from the blister cap, which then presses against the blister card, formed correspondingly smaller. This opens up the possibility of making the product, which is preferably a washing machine tablet or dishwashing tablet, more versatile, since it has to withstand less pressure.
Beispielsweise könnte so eine Geschirrspültablette verwendet werden, die aus nur locker zusammengepresstem Granulat besteht. Eine solche Tablette würde bei der Entnahme aus einer herkömmlichen Blisterverpackung, bei der zum Einreißen der Blisterkarte der Druck auf die Blisterhaube vollständig von der Tablette übertragen werden muss, möglicherweise zerbröseln. Auch könnten bei der erfindungsgemäßen Blisterverpackung nun auch Mehrkomponenten- Produkte verwendet werden, bei denen zumindest eine Komponente druckempfindlich ist. For example, such a dishwasher tablet could be used, which consists of only loosely compressed granules. Such a tablet, when removed from a conventional blister pack in which the tearing of the blister card requires the pressure on the blister cap to be completely transferred from the tablet, would possibly crumble. It would also be possible to use multicomponent products in the blister pack according to the invention in which at least one component is pressure-sensitive.
Beispielsweise ist eine Komponente ein Gel. For example, a component is a gel.
In einem Ausführungsbeispiel wird wenigstens ein Drittel oder die Hälfte der Druckkraft über die innere Auflagefläche auf die Blisterkarte geleitet. Dies bedeutet für den letzteren Fall, dass das Produkt in der Produktkammer bei der Entnahme um wenigstens 50 % gegenüber dem Fall entlastet wird, bei der die Druckkraft auf die Blisterhaube vollständig von dem Produkt auf die Blisterkarte übertragen wird. In one embodiment, at least a third or half of the compressive force is directed to the blister card via the inner support surface. In the latter case, this means that the product in the product chamber is relieved by at least 50% in the removal from the case in which the pressure force on the blister cap is completely transferred from the product to the blister card.
Anhand dem in der Zeichnung dargestellten Ausführungsbeispiel wird die Erfindung näher erläutert. Es zeigen: Figur 1 eine Blisterverpackung mit einem Produkt in der Draufsicht; und Reference to the embodiment shown in the drawing, the invention is explained in detail. Show it: Figure 1 shows a blister pack with a product in plan view; and

Die Figuren 1 und 2 zeigen eine Blisterverpackung, die in ihrer Gesamtheit mit 1 bezeichnet wird. Die Blisterverpackung 1 umfasst eine flache Blisterkarte 10 und eine Blisterhaube 20. Die Figures 1 and 2 show a blister pack, which is designated in its entirety by 1. The blister pack 1 comprises a flat blister card 10 and a blister hood 20. The
Blisterkarte 10 und die Blisterhaube 20 umschließen oder bilden eine Produktkammer 2 für ein Produkt 3, hier in Form einer quaderförmigen Tablette. Im hier dargestellten Ausführungsbeispiel sollen die Ausmaße der Tablette 3 bis 5 cm (Länge) x 2 bis 4 cm (Breite) x 1 bis 3 cm (Höhe) betragen. Blister card 10 and the blister cap 20 enclose or form a product chamber 2 for a product 3, here in the form of a cuboid tablet. In the embodiment shown here, the dimensions of the tablet should be 3 to 5 cm (length) x 2 to 4 cm (width) x 1 to 3 cm (height).
Die Blisterkarte 10 weist eine rechteckige, mit abgerundeten Ecken versehene Schwächungslinie 1 1 in Form einer Perforationslinie auf. Die Schwächungslinie 1 1 liegt unterhalb eines Rands 21 der Blisterhaube 20 (siehe insbesondere Figur 2). Der Rand 21 liegt mit einer inneren Auflagefläche 22 und einer äußeren Auflagefläche 23 auf der Blisterkarte 10 auf. Zwischen der äußeren The blister card 10 has a rectangular, provided with rounded corners weakening line 1 1 in the form of a perforation. The weakening line 1 1 lies below an edge 21 of the blister cap 20 (see in particular Figure 2). The edge 21 rests on the blister card 10 with an inner bearing surface 22 and an outer bearing surface 23. Between the outside
Auflagefläche 23 und der Blisterkarte 10 sind Dichtmittel und/oder Haltemittel 4 (im Folgenden: Dichtmittel) vorgesehen. Das heißt, die äußere Auflagefläche 23 liegt nur mittelbar auf der Blisterkarte 10 auf. Die Dichtmittel haben die Aufgabe, einerseits eine feste Verbindung zwischen Blisterhaube 20 und Blisterkarte 10 zu schaffen und andererseits die Produktkammer 2 mit dem darin befindlichen Produkt 3 vor Umgebungseinflüssen wie Feuchtigkeit zu schützen. Support surface 23 and the blister card 10 are sealing means and / or holding means 4 (hereinafter: sealant) is provided. That is, the outer support surface 23 rests only indirectly on the blister card 10. The sealing means have the task, on the one hand to provide a firm connection between blister cap 20 and blister card 10 and on the other hand to protect the product chamber 2 with the product 3 therein against environmental influences such as moisture.
Wie der Figur 2 zu entnehmen ist, liegt beim hier dargestellten Ausführungsbeispiel der äußere Rand 23 in einer Ebene, die leicht beabstandet zur Ebene der Blisterkarte 10 ist. Zwischen den Dichtmitteln 4 und der inneren Auflagefläche 22 verbleibt ein kleiner Hohlraum 5 oberhalb der Schwächungslinie bzw. der Perforationslinie 1 1. Man erkennt, dass durch die Auflage der inneren Auflagefläche 22 auf der Blisterkarte 10 eine räumliche Trennung zwischen dem Hohlraum 5 und Produktkammer 2 gegeben ist. Dies führt dazu, dass obgleich die innere Auflagefläche 22 frei von Dichtmitteln ist, die Barrierewirkung der Blisterkarte 10 durch die Schwächungslinie 1 1 nur wenig oder gar nicht beeinträchtigt wird. Ein Gas oder Feuchtigkeit, das bzw. die durch die As can be seen from FIG. 2, in the exemplary embodiment illustrated here, the outer edge 23 lies in a plane which is slightly spaced from the plane of the blister card 10. Between the sealing means 4 and the inner support surface 22, a small cavity 5 remains above the weakening line or the perforation line 1 1. It can be seen that a spatial separation between the cavity 5 and product chamber 2 by the support of the inner support surface 22 on the blister card 10 is. As a result, although the inner bearing surface 22 is free of sealing means, the barrier effect of the blister card 10 is only slightly or not impaired by the weakening line 11. A gas or moisture that flows through the
Perforationslinie 1 1 in den Hohlraum 5 gelangt, gelangt nicht oder nicht ohne weiteres in die Produktkammer 2. Dies unterscheidet sich von dem Stand der Technik, bei dem sich die Perforation line 1 1 enters the cavity 5, does not reach or not readily in the product chamber 2. This differs from the prior art, in which the
Schwächungslinie 1 1 in der Blisterkarte 10 direkt unterhalb Produktkammer 2 befindet. Gegenüber dem Stand der Technik kann so die Schwächung der Barrierewirkung durch Vorsehen der Schwächungslinie 1 1 vermieden bzw. reduziert werden. Wie der Figur 1 entnommen werden kann, laufen die Dichtmittel 4 mit der äußeren Auflagefläche auch in Form eines Rechtsecks mit einem geschlossenen Umfang um die Produktkammer 2 herum. Dies gilt sinngemäß auch für die Schwächungslinie 1 1 und der inneren Auflagefläche 22. Line of weakness 1 1 in the blister card 10 is located directly below the product chamber 2. Compared to the prior art, the weakening of the barrier effect can thus be avoided or reduced by providing the weakening line 11. As can be seen from FIG. 1, the sealing means 4 run around the product chamber 2 with the outer bearing surface, also in the form of a rectangular area with a closed circumference. This applies mutatis mutandis to the weakening line 1 1 and the inner bearing surface 22nd
Figur 3, welche auf Figur 2 aufsetzt, soll schematisch die Kräfte zeigen, die auf die FIG. 3, which is superimposed on FIG. 2, is intended to show schematically the forces which are on the
Blisterverpackung 1 wirken, wenn durch eine vertikale Druckkraft F auf die Blisterhaube 20 von oben das Produkt 3 aus der Produktkammer 2 gedrückt werden soll. Es wird dabei davon ausgegangen, dass die Blisterhaube 20 ein vergleichsweise steifes Bauteil darstellt. In diesem Fall wird die Druckkraft F über den Haubendeckel 24 vollständig auf die Seitenwände 25 der Blister 1 act when the product 3 is to be pressed from the product chamber 2 by a vertical pressure force F on the blister cover 20 from above. It is assumed that the blister cap 20 is a comparatively rigid component. In this case, the pressure force F on the hood cover 24 completely on the side walls 25 of
Blisterhaube 20 geleitet. Entsprechend teilt sich die Druckkraft F hälftig auf einen linken Abschnitt 22i der inneren Auflagefläche und einen rechten Abschnitt 22r der Auflagefläche 22 auf Blister hood 20 headed. Correspondingly, the pressure force F divides in half on a left section 22i of the inner bearing surface and a right section 22 r of the bearing surface 22
(unberücksichtigt bleiben dabei die dazu senkrechten Abschnitte der Auflagefläche 22, die in Figur 3 nicht dargestellt sind). (Disregarded remain the perpendicular sections of the support surface 22, which are not shown in Figure 3).
Man erkennt, dass die an den jeweiligen Abschnitten 22i, 22r wirkenden Kräfte F/2 in Verbindung mit entsprechenden Gegenkräften F'/2 zu einer Scherspannung an der Schwächungslinie 1 1 führt. Die Schwächungslinie 1 1 reißt entsprechend ein, wenn die Druckkraft F genügend hoch ist. It can be seen that the forces F / 2 acting on the respective sections 22i, 22 r in conjunction with corresponding opposing forces F '/ 2 lead to a shearing stress on the line of weakness 1 1. The line of weakness 1 1 breaks accordingly when the pressure force F is sufficiently high.
Danach kann das Produkt 3 durch die sich dann ergebene Öffnung in der Blisterkarte 10 entnommen werden. Im hier geschilderten Beispiel bleibt dabei das Produkt 3 praktisch völlig frei von Druckspannungen oder anderen Spannungsspitzen. Auch sei darauf hingewiesen, dass bei der Entnahme des Produkts 3 keine Haltekräfte überwunden werden müssen, um die Verbindung zwischen innerer Auflagefläche 22 und Blisterkarte 10 (es handelt sich um eine bloße Auflage ohne jegliche Dichtmittel) zu trennen. Thereafter, the product 3 can be removed through the then resulting opening in the blister card 10. In the example described here, the product 3 remains practically completely free from compressive stresses or other voltage peaks. It should also be noted that when removing the product 3 no holding forces must be overcome in order to separate the connection between the inner support surface 22 and blister card 10 (it is a mere edition without any sealant).
Wenn davon ausgegangen wird, dass die Blisterhaube 20 nur eine gewisse Steifigkeit aufweist und der Haubendeckel 24 bei Druckbeaufschlagung nachgibt, wird ein gewisser Anteil der Druckraft F über das Produkt 3 auf die Blisterkarte 10 geleitet, was dann ebenfalls zu Schwerspannungen in der Schwächungslinie 1 1 führt. Aber auch hier muss das Produkt 3 nicht die gesamte Druckkraft aufnehmen, weil - in Abhängigkeit von Haubendeckel 25 und Seitenwänden 25 - zumindest ein kleiner Anteil der Druckkraft über die Struktur der Blisterhaube 20 abfließt. If it is assumed that the blister cap 20 has only a certain rigidity and the hood cover 24 yields when pressurized, a certain proportion of the pressure force F is passed over the product 3 on the blister card 10, which then also leads to tension in the line of weakness 1 1 , But even here, the product 3 does not have to absorb the entire compressive force, because - depending on the hood lid 25 and side walls 25 - at least a small proportion of the pressure force flows through the structure of the blister cover 20.
Schließlich sei auch der Fall skizziert, dass die Blisterhaube 20, zumindest im Bereich des Haubendeckels 24 und der Seitenwände 25, nur eine sehr kleine Steifigkeit aufweist. In diesem Fall wird praktisch die gesamte Druckkraft über das Produkt 3 auf die Blisterkarte 10 geleitet. Hinsichtlich der Druckbelastung für das Produkt würde dies gegenüber dem Stand der Technik keinen Nachteil bedeuten, da auch hier die gesamte Druckkraft F zum Öffnen der Produktkammer 3 von dem Produkt 3 aufgenommen werden muss. Aber es verbleibt der Vorteil, dass durch die erfindungsgemäße Anordnung der Schwächungslinie 1 1 (separat von der Produktkammer 3, getrennt durch die innere Auflagefläche 22) die Barrierewirkung der Blisterkarte 10 wesentlich geringer oder gar nicht beeinträchtigt wird. Bezugszeichenliste Finally, the case is also sketched that the blister cap 20, at least in the region of the hood cover 24 and the side walls 25, has only a very small rigidity. In this case, almost the entire pressure force is passed over the product 3 on the blister card 10. With regard to the pressure load for the product, this would mean no disadvantage compared with the prior art, since here too the entire pressure force F must be absorbed by the product 3 to open the product chamber 3. But there remains the advantage that the barrier effect of the blister card 10 is substantially less or not affected by the inventive arrangement of the weakening line 1 1 (separately from the product chamber 3, separated by the inner support surface 22).
