Description

Die Erfindung betrifft eine Verpackungseinrichtung mit einer Oberfolie und einer Unterfolie, die derart geformt und miteinander verbindbar sind, daß sie zwischen sich mehrere, in wenigstens einer Reihe angeordnete Aufnahmefächer für Tabletten o.dgl. bilden.The invention relates to a packaging device with an upper film and a lower film, which are shaped and can be connected to one another in such a way that they have a plurality of receiving compartments for tablets or the like arranged between them in at least one row. form.

Bei Verpackungseinrichtungen der eingangs genannten Art, die in vielfältiger Form zum Verpacken von Pharmazeutika, Kosmetika oder Lebensmittel o.dgl. eingesetzt werden, ist die Unterfolie mit den napfartigen Vertiefungen versehen, die nach Einbringen des zu verpackenden Materials mit einer ebenen Oberfolie abgedeckt werden. Das Verbinden zwischen Oberfolie und Unterfolie erfolgt mittels eines Heißsiegelklebers. Bei einer häufig verwendeten Verpackungseinrichtung wird als Unterfolie eine PVC-Folie benutzt, in der die napfförmigen Vertiefungen thermisch mit Hilfe von Druckluft oder Saugluft erzeugt werden, wobei unter Umständen noch eine Vorverformung mittels Stempeln vorgenommen wird. Als Oberfolie dient häufig eine Aluminiumfolie, die zwischen den napfförmigen Vertiefungen mittels eines Heißsiegelklebers an der Unterfolie befestigt wird. Derartige Verpackungseinrichtungen sind insbesondere als sogenannte Durchdrückpackungen bekannt, bei welchen mittels Druck auf die relativ weichen Vertiefungen der verpackte Gegenstand durch die dann aufreißende Oberfolie hindurchgedrückt werden kann. Ähnliche Verpackungseinrichtungen werden auch als Aufreißpackungen eingesetzt, bei welchen die Oberfolie mit einer nicht mit der Unterfolie verbundenen Grifflasche versehen ist, an der die Oberfolie abgezogen werden kann.In packaging devices of the type mentioned, the like in various forms for packaging pharmaceuticals, cosmetics or food. are used, the bottom film is provided with the cup-like depressions, which are covered with a flat top film after introducing the material to be packaged. The connection between the top film and the bottom film is made using a heat seal adhesive. In the case of a frequently used packaging device, a PVC film is used as the bottom film, in which the cup-shaped depressions are generated thermally with the aid of compressed air or suction air, with pre-deformation possibly also being carried out by means of stamping. An aluminum foil is often used as the top foil, which is attached to the bottom foil between the cup-shaped depressions by means of a heat seal adhesive. Such packaging devices are known in particular as so-called push-through packs, in which pressure is applied to the relative soft depressions, the packaged item can be pushed through the then opening top film. Similar packaging devices are also used as tear-open packs, in which the top film is provided with a grip tab which is not connected to the bottom film and on which the top film can be pulled off.

Wenn das zu verpackende Material oder die zu verpackenden Gegenstände absolut dicht verpackt werden müssen, beispielsweise weil sie einen flüchtigen Stoff wie Alkohol o.dgl. enthalten, so ist es auch bekannt, die Unterfolie aus mehreren Schichten herzustellen, die dann ebenfalls mit einer Aluminiumfolie als Oberfolie abgedeckt wird. Die mehrschichtige Folie enthält in der Regel als Trägermaterial Aluminium. Die zusätzlichen Schichten, insbesondere Kunststoffschichten aus PVC oder Polyamid, sind deshalb notwendig, weil bei dem Herstellen der napfförmigen Vertiefungen, die mittels Eindrücken von Stempeln gebildet werden, das Aluminium seine Dichtheit verliert und nicht mehr porenfrei geschlossen ist. Auch bei derartigen mehrschichtigen Folien mit dem Trägermaterial Aluminium sind dem Verformen mittels Stempeln Grenzen gesetzt, da die Gefahr besteht, daß das Aluminium reißt. Wenn relativ große Tabletten und insbesondere dicke Tabletten verpackt werden sollen, so ist es notwendig, eine napfförmige Vertiefung zu schaffen, deren Grundfläche wesentlich größer als die Projektion der Tablette ist. Dadurch ist es möglich, die Verformung auf relativ große Wandbereiche zu verteilen, so daß die Gefahr eines Reißens des Aluminiums beherrscht werden kann. Die Anzahl der napfförmigen Vertiefungen, die auf eine Fläche einer vorgegebenen Größe der Unterfolie unterbringbar sind, ist somit beschränkt.If the material to be packaged or the items to be packaged must be packed absolutely tight, for example because they contain a volatile substance such as alcohol or the like. contain, it is also known to produce the lower film from several layers, which is then also covered with an aluminum film as the upper film. The multilayer film usually contains aluminum as the carrier material. The additional layers, in particular plastic layers made of PVC or polyamide, are necessary because when the cup-shaped depressions are produced, which are formed by pressing in stamps, the aluminum loses its tightness and is no longer closed without pores. Even with such multilayer films with the carrier material aluminum there are limits to the deformation by means of stamping, since there is a risk that the aluminum will tear. If relatively large tablets and in particular thick tablets are to be packaged, it is necessary to create a cup-shaped depression, the base of which is considerably larger than the projection of the tablet. This makes it possible to distribute the deformation over relatively large wall areas, so that the risk of the aluminum tearing can be controlled. The number of cup-shaped depressions which can be accommodated on a surface of a predetermined size of the lower film is thus limited.

Der Erfindung liegt die Aufgabe zugrunde, eine Verpackungseinrichtung der eingangs genannten Art zu schaffen, die eine bessere Ausnutzung der Grundfläche der Unterfolie ermöglicht.The invention has for its object to provide a packaging device of the type mentioned that enables better use of the base of the bottom film.

Diese Aufgabe wird dadurch gelöst, daß die Oberfolie und die Unterfolie jeweils aus Aluminiumfolien bestehen und daß sowohl die Oberfolie als auch die Unterfolie mit napfförmigen Vertiefungen versehen sind, die sich jeweils zu eine Aufnahmefach ergänzen.This object is achieved in that the top film and the bottom film each consist of aluminum foils and that both the top film and the bottom film are provided with cup-shaped depressions, which each add to a receiving compartment.

Durch die erfindungsgemäße Ausbildung wird erreicht, daß die Tiefe einer napfartigen Vertiefung auch dann wesentlich reduziert werden kann, wenn große oder dicke Tabletten aufgenommen werden können, da das Aufnahmefach sich aus zwei derartiger napfartiger Vertiefungen zusammensetzt. Dadurch ist es möglich, die Aufnahmefächer wesentlich dichter nebeneinander anzuordnen, so daß sich eine Materialeinsparung für die Unterfolie und die Oberfolie ergeben. Diese Materialeinsparung beträgt in der Größenordnung von 40% bis 60%. Darüber hinaus ergibt sich der Vorteil, daß die entsprechend kleineren Verpackungseinrichtungen auch in den nachfolgenden Verpackungseinheiten dichter gepackt werden können, so daß es kleinere Schachteln und kleine Umkartons gibt. Damit läßt sich der Materialverbrauch wesentlich reduzieren. Da die Tiefe der Vertiefungen und damit die Stärke der Verformung beim Erzeugen der Vertiefungen wesentlich reduziert werden kann, ist es unter Umständen auch möglich, Folien aus Aluminium oder einer Aluminiumlegierung zu verwenden, die keine Stützfolien erfordern. Dadurch ergibt sich der weitere Vorteil, daß die Verpackungseinrichtung nur aus einem Material besteht und somit relativ einfach recyclebar ist.The configuration according to the invention ensures that the depth of a cup-like depression can also be significantly reduced if large or thick tablets can be accommodated, since the receiving compartment is composed of two such cup-like depressions. This makes it possible to arrange the compartments much closer together so that there is a material saving for the lower film and the upper film. This material saving is of the order of 40% to 60%. In addition, there is the advantage that the correspondingly smaller packaging devices can also be packed more densely in the subsequent packaging units, so that there are smaller boxes and small outer cartons. This can significantly reduce the material consumption. Since the depth of the depressions and thus the strength of the deformation can be significantly reduced when producing the depressions, it is also possible under certain circumstances to use foils made of aluminum or an aluminum alloy that do not require any support foils. This has the further advantage that the packaging device consists of only one material and is therefore relatively easy to recycle.

Fig. 1 zeigt eine Abgabeeinheit einer Verpackungseinrichtung (10), die beispielsweise zehn Aufnahmefächer (11) für jeweils eine Tablette (12) aufweist. Die Verpackungseinrichtung (10) wird aus einer Oberfolie (13) und einer Unterfolie (14) gebildet, die einer Verpackungsmaschine in Form von Rollen vorgelegt werden, auf die diese Folien aufgewickelt sind. Die von den Rollen abgewickelte Oberfolie (13) und die Unterfolie (14) durchlaufen bahnförmig Formstationen, in denen sowohl die Oberfolie (13) als auch die Unterfolie (14) mit napfförmigen Vertiefungen (15, 16) versehen werden, die später beim Zusammenfügen von Oberfolie (13) und Unterfolie (14) jeweils ein Aufnahmefach (11) bilden. Die Unterfolie (14) durchläuft im wesentlichen horizontal eine Abfülleinrichtung, in welcher die napfförmigen Vertiefungen (16) mit den Tabletten (12) befüllt werden. Anschließend wird die von oben zugeführte Oberfolie (13) derart über die Unterfolie (14) gelegt, daß die Vertiefungen (15, 16) miteinander fluchten. Die Oberfolie (13) und die Unterfolie (14) werden in dem Bereich außerhalb der Vertiefungen (15, 16) mit einem Heißsiegellack versehen. Nach dem Zusammenfügen werden Oberfolie (13) und Unterfolie (14) mittels des Heißsiegellackes in einer entsprechenden Station miteinander verbunden. Die bahnförmig zugeführte Oberfolie (13) und Unterfolie (14) weisen über die Breite gesehen ein Mehrfaches der in Fig. 1 dargestellten Abgabeeinheit dar. Sie werden später nach dem Verpacken auf die Größe der in Fig. 1 dargestellten Abgabeeinheit zurechtgeschnitten.1 shows a delivery unit of a packaging device (10) which has, for example, ten receiving compartments (11) for one tablet (12) each. The packaging device (10) is formed from an upper film (13) and a lower film (14), which are presented to a packaging machine in the form of rolls on which these films are wound. The upper film (13) unwound from the rolls and the lower film (14) pass through web-like forming stations, in which both the upper film (13) and the lower film (14) are provided with cup-shaped depressions (15, 16), which are later combined when The upper film (13) and lower film (14) each form a receiving compartment (11). The bottom film (14) runs essentially horizontally through a filling device in which the cup-shaped depressions (16) are filled with the tablets (12). The upper film (13) fed from above is then placed over the lower film (14) in such a way that the depressions (15, 16) are aligned with one another. The top film (13) and the bottom film (14) are provided with a heat seal lacquer in the area outside the depressions (15, 16). After the joining, the top film (13) and bottom film (14) are connected to one another in a corresponding station by means of the heat-sealing lacquer. The web-fed top film (13) and bottom film (14) are several times the width of the delivery unit shown in FIG. 1. They are cut to size later after packaging to the size of the delivery unit shown in FIG. 1.

Die Unterfolie (14) und die Oberfolie (13) sind jeweils mit einer Stützfolie versehene Aluminiumfolien, die eine Dicke von etwa 50 Mikrometer bis 60 Mikrometer aufweisen. Bei einer Ausführungsform sind zwei Aluminiumfolien vorgesehen, zwischen denen eine Stützfolie aus Kunststoff, beispielsweise PVC, angeordnet ist. Wie schon erwähnt wurde, sind sowohl in die Unterfolie (14) als auch in die Oberfolie (13) napfartige Vertiefungen (15, 16) eingearbeitet, die insbesondere durch Stempeln in der Formstation eingedrückt werden. Da sowohl die Unterfolie (14) als auch die Oberfolie (13) mit diesen napfartigen Vertiefungen (15, 16) versehen sind, lassen sich relativ große Tabletten (12) in den Aufnahmefächern (11) unterbringen, ohne daß eine der napfartigen Vertiefungen (15, 16) eine Tiefe aufweisen muß, die der Dicke der Tablette (12) entspricht. Da die Tiefe der napfartigen Vertiefungen (15, 16) mithin geringer ist, lassen sich die napfartigen Vertiefungen (15, 16) auch in ihrer Grundfläche verkleinern, ohne daß die Gefahr besteht, daß in den Aluminiumfolien Risse auftreten.The lower film (14) and the upper film (13) are each provided with a supporting film aluminum films which have a thickness of about 50 microns to 60 microns. In one embodiment, two aluminum foils are provided, between which a support foil made of plastic, for example PVC, is arranged. As already mentioned, are both in the bottom film (14) as well as in the upper film (13) cup-like depressions (15, 16), which are pressed in in particular by stamping in the forming station. Since both the lower film (14) and the upper film (13) are provided with these cup-like depressions (15, 16), relatively large tablets (12) can be accommodated in the receiving compartments (11) without one of the cup-like depressions (15 , 16) must have a depth which corresponds to the thickness of the tablet (12). Since the depth of the cup-like depressions (15, 16) is therefore less, the cup-like depressions (15, 16) can also be reduced in their base area without the risk of cracks occurring in the aluminum foils.

Bei dem dargestellten Ausführungsbeispiel dienen die Aufnahmefächer (11) zur Aufnahme einer Tablette, die im wesentlichen eine zylindrische Form aufweist und deren Enden halbkugelförmig ausgebildet sind. Die napfartigen Vertiefungen (15, 16) besitzen entsprechend eine ovale Grundfläche. Sie sind in ihrem mittleren Bereich, wie in Fig. 3 gezeigt ist, etwa halbzylindrisch geformt, an den sich jeweils ein Teil kugelförmig geformter Endbereich anschließt. Da die für die Herstellung der napfartigen Vertiefungen (15, 16) benötigte Grundfläche relativ klein ist, lassen sich die Aufnahmefächer (11) wesentlich näher als bisher aneinanderrücken. Wie Fig. 1 zeigt, haben die napfartigen Vertiefungen (15, 16) zwischen ihren Längsseiten einen gegenseitigen Abstand, der etwa der Hälfte ihrer Breite entspricht. Zwischen den Stirnenden der napfartigen Vertiefungen (15, 16) ist in etwa der gleiche Abstand belassen, der bei dem dargestellten Ausführungsbeispiel etwa einem Drittel der napfförmigen Vertiefungen entspricht.In the exemplary embodiment shown, the receiving compartments (11) serve to hold a tablet which has a substantially cylindrical shape and the ends of which are hemispherical. The cup-like depressions (15, 16) accordingly have an oval base. In their central region, as shown in FIG. 3, they are roughly semi-cylindrical, each of which is followed by a part of a spherically shaped end region. Since the base area required for the production of the cup-like depressions (15, 16) is relatively small, the receiving compartments (11) can be moved closer together than before. As shown in FIG. 1, the cup-like depressions (15, 16) have a mutual distance between their long sides, which corresponds to approximately half their width. Between the ends of the cup-like depressions (15, 16) is left approximately the same distance, which corresponds to about a third of the cup-shaped depressions in the illustrated embodiment.

In den nicht verformten Bereichen zwischen den Aufnahmefächern (11) sind Perforationsreihen (17, 18) angebracht, entlang welchen sich die Verpackungseinrichtung (10) in Einzelpackungen trennen läßt.In the non-deformed areas between the receiving compartments (11) rows of perforations (17, 18) are provided, along which the packaging device (10) can be separated into individual packs.

Wie aus Fig. 1 zu ersehen ist, ist zwischen der Unterfolie (14) und der Oberfolie (13) in dem nicht verformten Bereich ein Heißsiegellack (19) aufgetragen. Dieser Heißsiegellack (19) ist so aufgetragen, daß jeweils neben einer Reihe von Aufnahmefächern (11) ein Handstreifen (20, 21) verbleibt, der frei von Heißsiegellack (19) ist. Die Unterfolie (14) und die Oberfolie (13) lassen sich somit im Bereich dieses Randstreifens (20) leicht voneinander trennen, wonach sie im Bereich des Heißsiegellacks (19) aufgerissen werden können (peeling).As can be seen from FIG. 1, a heat seal lacquer (19) is applied between the lower film (14) and the upper film (13) in the non-deformed area. This heat seal lacquer (19) is applied in such a way that a hand strip (20, 21) remains next to a row of receiving compartments (11) and is free of heat seal lacquer (19). The bottom film (14) and the top film (13) can thus be easily separated from one another in the region of this edge strip (20), after which they can be torn open in the region of the heat-sealing lacquer (19) (peeling).

Bei dem Ausführungsbeispiel ist vorgesehen, daß die napfförmigen Vertiefungen (15) der Oberfolie (13) nicht mit den napfförmigen Vertiefungen (16) der Unterfolie (14) identisch sind. Wie aus Fig. 2 und 3 zu ersehen ist, sind die napfförmigen Vertiefungen (16) der Unterfolie (14) tiefer. Die napfförmigen Vertiefungen (15) der Oberfolie (13) besitzen einen mittleren, abgeflachten, ebenen Bereich. Dieser ebene Bereich erlaubt es, die Oberfolie (13) dort zu bedrucken. Wenn jedoch Tabletten (12) mit einem größeren Durchmesser verpackt werden sollen, so können die Vertiefungen (15) der Oberfolie (13) ebenfalls die maximale Tiefe aufweisen, die etwa die Hälfte ihrer größten Breite entspricht.In the exemplary embodiment it is provided that the cup-shaped depressions (15) of the upper film (13) are not identical to the cup-shaped depressions (16) of the lower film (14). As can be seen from FIGS. 2 and 3, the cup-shaped depressions (16) of the lower film (14) are deeper. The cup-shaped depressions (15) of the upper film (13) have a central, flattened, flat area. This flat area allows the top film (13) to be printed there. However, if tablets (12) with a larger diameter are to be packaged, the depressions (15) of the upper film (13) can also have the maximum depth, which corresponds to approximately half their greatest width.

Das anhand von Fig. 1 bis 3 erläuterte Prinzip läßt sich natürlich auch verwirklichen, wenn runde oder kugelförmige Tabletten o.dgl. verpackt werden sollen. In diesem Fall erhalten dann die napfförmigen Vertiefungen (15, 16) der Oberfolie (13) und der Unterfolie (14) eine entsprechende Grundfläche.The principle explained with reference to FIGS. 1 to 3 can of course also be realized if round or spherical tablets or the like. should be packed. In this case, the cup-shaped depressions (15, 16) of the upper film (13) and the lower film (14) are given a corresponding base area.

Da die Aufnahmefächer (11) wesentlich dichter als bisher aneinander herangerückt werden können, ergibt sich ein wesentlich geringerer Verbrauch für das Material der Oberfolie (13) und der Unterfolie (14). Die Materialersparnis beträgt zwischen 40% und 60%. Darüber hinaus ergibt sich der Vorteil, daß die Abgabeeinheiten der Verpackungseinrichtung, wie sie in Fig. 1 dargestellt sind, in kleineren Schachteln verpackt werden können.Since the receiving compartments (11) can be moved closer together than before, the material used for the upper film (13) and the lower film (14) is significantly lower. The material savings are between 40% and 60%. In addition, there is the advantage that the delivery units of the packaging device, as shown in Fig. 1, can be packed in smaller boxes.

Diese kleinere Schachteln können dann entsprechend auch in kleineren Kartons verpackt werden. Damit ergibt sich auch für die weitere Verpackung der Verpackungseinrichtung eine deutlichere Einsparung an Verpackungsmaterial.These smaller boxes can then be packed in smaller boxes accordingly. This also results in a clear saving in packaging material for the further packaging of the packaging device.

Bei einer abgewandelten Ausführungsform sind die Oberfolie (13) und die Unterfolie (14) auch im Bereich der Randstreifen (20) mit dem Heißsiegellack miteinander verbunden. Um in diesem Fall eine Trennung vornehmen zu können, wird im mittleren Bereich entlang der Perforationsreihe (18) ein heißsiegellackfreier Bereich (22) vorgesehen, der in Fig. 1 strichpunktiert eingezeichnet ist. Um eine Tablette (12) in diesem Falle entnehmen zu können, muß eine Einzelpackung durch Trennen an den zugehörigen Perforationsreihen (17, 18) freigelegt werden. Dabei wird dann auch der nicht mit einem Heißsiegellack verbundene Randbereich (22) freigelegt, so daß dann die Einzelpackung geöffnet werden kann.In a modified embodiment, the top film (13) and the bottom film (14) are also connected to one another in the region of the edge strips (20) with the heat seal lacquer. In order to be able to carry out a separation in this case, a region (22) free of heat-sealing lacquer is provided in the central region along the row of perforations (18), which is shown in dash-dot lines in FIG. 1. In order to be able to remove a tablet (12) in this case, a single pack must be exposed by separating the associated rows of perforations (17, 18). The edge area (22) which is not connected with a heat seal lacquer is then also exposed, so that the individual pack can then be opened.
