Abstract

A primary packaging for laminar objects is disclosed, comprising an upper (3) and a lower strip (2). The fusion of the strips (2, 3) encloses an inner region, suitable for accepting a laminar object and comprises, in the outer areas of said strips, regions where both packaging strips are not joined to each other and where said strips are not congruently arranged one on the other.

Description

Verpackung flächenförmiger Gegenstände mit verbesserter Aufreisseigenschaft.Packaging of sheet-like objects with improved tear properties.
Die Erfindung betrifft die Verpackung flächenförmiger Gegenstände wie zum Beispiel film- oder oblatenartige Arzneimittel, die auch als Wafer bezeichnet werden.The invention relates to the packaging of sheet-like objects such as, for example, film-like or wafer-like pharmaceuticals, which are also referred to as wafers.
Film- oder oblatenartige Arzneimittel zur oralen Verabreichung sind zum Beispiel aus der Offenlegungsschrift DE 24 32 925 A1 und dem Patent EP 219 762 B1 bekannt. Sie unterscheiden sich von konventionellen festen Darreichungsformen wie Tabletten oder Kapseln insbesondere durch ihre geometrische Form und ihre Flexibilität. So besitzen diese Wafer im allgemeinen eine Fläche zwischen etwa 2 und etwa 20 cm2 und sind nur zwischen 50 und 500 μm dick. Aufgrund dieser geringen Dicke sind diese Wafer im allgemeinen auch sehr flexibel. Viele sind zudem mukoadhäsiv ausgestattet, was bei oraler Einnahme zu einem Anhaften dieser Darreichungsform am Gaumen führt.Film-like or wafer-like drugs for oral administration are known, for example, from published patent application DE 24 32 925 A1 and patent EP 219 762 B1. They differ from conventional solid dosage forms, such as tablets or capsules, particularly in their geometric shape and flexibility. These wafers generally have an area between approximately 2 and approximately 20 cm 2 and are only between 50 and 500 μm thick. Because of this small thickness, these wafers are generally also very flexible. Many are also mucoadhesive, which leads to the adherence of this dosage form to the palate when taken orally.
Verpackt werden solche Wafer in Plastikcontainer, wie sie zum Beispiel aus dem US-Design 371 ,723 bekannt sind. Auch ist es möglich, derartige Wafer in eine Blisterpackung (sog. Tiefziehverpackung) abzulegen. Solche sind zum Beispiel aus der britischen Offenlegungsschrift GB 2,311 ,760 A bekannt. Schliesslich kann man diese Wafer auch in einen aus zwei identischen Schichten bestehenden Siegelbeutel einpacken. Vom Gesichtspunkt des benötigen Materials und der Einfachheit der Herstellung ist diese Lösung in den meisten Fällen am vorteilhaftesten. Eine entsprechende Primärverpackung ist im amerikanischen Patent US 3,007,848 beschrieben.Such wafers are packaged in plastic containers, as are known, for example, from US design 371, 723. It is also possible to place such wafers in a blister pack (so-called thermoformed packaging). Such are known, for example, from British Laid-Open GB 2,311,760 A. Finally, these wafers can also be packed in a sealing bag consisting of two identical layers. From the point of view of the material required and the simplicity of manufacture, this solution is most advantageous in most cases. A corresponding primary packaging is described in US Pat. No. 3,007,848.
Allerdings können Schwierigkeiten beim Öffnen dieser Verpackungen auftreten, da sie aufgrund der geringen Fläche und der geringen Höhe nur schwer anzufassen sind. Daher wurde eine Verpackung entwickelt, welche den Wafer zwischen zwei Folien einschliesst, wobei Ober- und Unterbahn übereinander liegen und derart miteinander verbunden werden, dass einerseits durch einen Verbund der Bahnen der Wafer ausreichend geschützt ist, andererseits an den Rändern Stellen existieren, an welche beide Bahnen nicht miteinander verbunden sind. Hier können die einzelnen Bahnen angefasst werden, um die Verpackung durch Aufreissen leichter zu öffnen. Diese Lösung ist in der deutschen Offenlegungsschrift DE 198 00 692 A1 beschrieben.However, difficulties can arise when opening this packaging because it is only due to the small area and the low height are difficult to handle. A packaging was therefore developed that encloses the wafer between two foils, the top and bottom webs lying one above the other and being connected to one another in such a way that the wafer is adequately protected by a bond between the webs, and on the other hand there are locations at the edges, both of which Lanes are not interconnected. The individual strips can be gripped here to make it easier to open the packaging by tearing it open. This solution is described in German Offenlegungsschrift DE 198 00 692 A1.
Ein weiterer Nachteil, den Primärverpackungen besitzen, die aus zwei gleichen bzw. zwei unterschiedlichen Packstoffbahnen hergestellt werden, besteht darin, dass die Kraft, die zum Öffnen dieser Verpackungen angewandt werden muss, dazu führen kann, dass Beschädigungen an dem empfindlichen Wafer auftreten können.Another disadvantage that primary packaging has, which is produced from two identical or two different packaging material webs, is that the force that has to be used to open these packaging can lead to damage to the sensitive wafer.
Da die Packstoffbahnen allerdings in der Regel äusserst dünn und zum Teil transparent sind, kann es insbesondere für ältere Menschen sehr umständlich sein, die Ober- bzw. Unterbahn einzeln zu greifen um die Primärverpackung aufzureissen.However, since the packaging material webs are usually extremely thin and partly transparent, it can be very cumbersome for older people in particular to grip the top and bottom web individually in order to tear open the primary packaging.
Aufgabe der Erfindung ist es daher, eine Primärverpackung für flächenförmige Gegenstände zur Verfügung zu stellen, die ein besonders einfaches, getrenntes Anfassen von Packstoffoberbahn und Packstoffunterbahn ermöglicht und dadurch ein bequemes Öffnen der Primärverpackung gewährleistet.The object of the invention is therefore to provide a primary packaging for sheet-like objects, which enables a particularly simple, separate handling of the packaging material upper and lower packaging material and thereby ensures a convenient opening of the primary packaging.
Gelöst wird die Aufgabe durch eine Primärverpackung für flächenförmige Gegenstände, die aus einer Oberbahn und einer Unterbahn besteht, wobei die Oberbahn und die Unterbahn der Primärverpacküng nicht kongruent übereinander liegen. Durch einen Verbund der Bahnen ist einerseits der flächenförmige Gegenstand (Wafer) ausreichend geschützt, vorzugsweise luftdicht eingesiegelt, andererseits besitzt die Primärverpackung mindestens an einem Aussenbereich einer Bahn des Verbunds der Bahnen Stellen, an welchen die beiden Packstoffbahnen nicht miteinander verbunden sind und an denen die Bahnen nicht kongruent übereinander liegen. Es existieren dort also Bereiche, in denen nur eine dieser Packstoffbahnen vorliegt.The object is achieved by a primary packaging for sheet-like objects, which consists of an upper web and a lower web, the upper web and the lower web of the primary packaging not lying congruently one above the other. The sheet-like object (wafer) is adequately protected, preferably, by combining the webs sealed airtight, on the other hand, the primary packaging has at least on one outer region of a web of the network of webs, where the two packaging material webs are not connected to each other and where the webs are not congruently one above the other. There are areas in which there is only one of these packaging material webs.
Auf diese Weise kann es erreicht werden, dass jede einzelne Packstoffbahn des Verbunds der Bahnen in der Primärverpackung an ihrem Aussenbereich mit Daumen und Zeigefinger von je einer Hand angefasst werden kann. Der Vorteil der erfindungsgemässen Prümärverpackung liegt nun darin, dass Daumen und Zeigefinger der einen Hand, mit der der Anwender eine Packstoffbahn anfasst, nicht in unmittelbarer Nähe zu dem Daumen und dem Zeigefinger der anderen Hand liegt. Statt dessen befinden sich Daumen und Zeigefinger der einen Hand beim Öffnen der erfindungsgemässen Primärverpackung räumlich versetzt (nach hinten und / oder seitlich) zu dem Daumen und dem Zeigefinger der anderen Hand. Dies führt zu einer deutlichen Reduktion der räumlichen Beanspruchung im Aussenbereich der Packstoffbahnen während des Öffnens der Primärverpackung, was letztlich zu einem wesentlich bequemeren Offen der Primärverpackung führt.In this way, it can be achieved that each individual packaging material web of the composite of webs in the primary packaging can be gripped by one hand on its outer region with the thumb and forefinger. The advantage of the test packaging according to the invention is that the thumb and index finger of one hand, with which the user touches a packaging material web, is not in close proximity to the thumb and index finger of the other hand. Instead, the thumb and index finger of one hand are spatially offset (to the rear and / or to the side) from the thumb and the index finger of the other hand when the primary packaging according to the invention is opened. This leads to a significant reduction in the spatial stress in the outer region of the packaging material webs during the opening of the primary packaging, which ultimately leads to a much more convenient opening of the primary packaging.
So kann schliesslich das gestellte Problem der vereinfachten Trennung von Ober- und Unterbahn einer durch Siegelung verbundenen Primärverpackung für flächenförmige Gegenstände (Wafer) gelöst werden.In this way, the problem of simplifying the separation of the top and bottom web of a primary packaging connected by sealing for sheet-like objects (wafers) can finally be solved.
Die folgenden Definitionen dienen der Erläuterung des erfindungsgemässen Gegenstands und seiner Anwendung.The following definitions serve to explain the object according to the invention and its application.
Unter flächenförmiger Gegenstand (1) im Sinne der vorliegenden Erfindung ist ein dreidimensionaler Gegenstand zu verstehen, der in einer Dimension nur eine sehr geringe Ausdehnung besitzt, relativ zu den beiden anderen Dimensionen. Die tatsächlichen Ausmasse dieses flächenförmigen Gegenstands sind nicht besonders bedeutungsvoll für diese Erfindung, bevorzugt sind jedoch flächenförmige Gegenstände, die eine Länge zwischen etwa 1 und 20 cm, eine Breite zwischen etwa 0,5 und 10 cm und eine Dicke von etwa 50 μm bis 1 cm besitzen. So kann ein flächenförmiger Gegenstand im Sinne der vorliegenden Erfindung quadratisch, rechteckig, rund oder oval sein, aber auch die Form und die Dimension einer im pharmazeutischen Bereich üblichen Tablette oder Kapsel annehmen. Besonders bevorzugt sind jedoch flächenförmige Gegenstände, deren Ausmasse an der Untergrenze der genannten Dimensionen liegen, weil deren Handhabung generell immer schwieriger wird, so dass die Vorteile der Erfindung hier besonders effektiv eingesetzt werden können. Solche besonders bevorzugten flächigen Gegenstände besitzen eine Länge zwischen etwa 1 und 3 cm, eine Breite zwischen etwa 0,5 und 2 cm und eine Dicke von etwa 50 μm bis 500 μm.Sheet-like object (1) in the sense of the present invention is to be understood as a three-dimensional object which has only a very small dimension in one dimension, relative to the other two dimensions. The actual dimensions of this sheet-like object are not particularly important for this invention, however, sheet-like objects are preferred which have a length between approximately 1 and 20 cm, a width between approximately 0.5 and 10 cm and a thickness of approximately 50 μm to 1 cm. In the sense of the present invention, a sheet-like object can be square, rectangular, round or oval, but can also take the form and the dimension of a tablet or capsule customary in the pharmaceutical field. However, particularly preferred are flat objects whose dimensions are at the lower limit of the dimensions mentioned, because their handling is generally becoming increasingly difficult, so that the advantages of the invention can be used particularly effectively here. Such particularly preferred flat objects have a length between approximately 1 and 3 cm, a width between approximately 0.5 and 2 cm and a thickness of approximately 50 μm to 500 μm.
Die Art des flächenförmigen Gegenstands ist nicht entscheidend für die Erfindung. Bevorzugt handelt es sich um Gegenstände, die aus unterschiedlichen Gründen luftdicht und / oder einzeln verpackt werden müssen. Hierbei kann es sich um Lebensmittel, Arzneimittel, Erfrischungstücher, Plastikkarten, biologisch aktives Material, (Klebe)Etiketten, TTS etc. handeln. Bevorzugt sind Darreichungsformen zur oralen Applikation, die auch physiologische Aktivstoffe oder pharmazeutische Wirkstoffe enthalten können.The type of sheet-like object is not critical to the invention. They are preferably objects which, for various reasons, have to be packed airtight and / or individually. This can be food, pharmaceuticals, refreshing towels, plastic cards, biologically active material, (adhesive) labels, TTS etc. Dosage forms for oral administration are preferred, which may also contain physiological active ingredients or pharmaceutical active ingredients.
Die Primärverpackung umfasst eine Packstoffoberbahn (3) und eine Packstoffunterbahn (2), die Bereiche (5) besitzen, die in innigem Kontakt zueinander vorliegen. Dadurch, dass hier die Packstoffunterbahn (2) und die Packstoffoberbahn (3) miteinander verbunden sind, ergibt sich ein Verbund von Packstoffoberbahn und Packstoffunterbahn, der einen inneren Bereich (4) umschliesst, der zur Aufnahme des flächenförmigen Gegenstands befähigt ist. Der innere Bereich (4) kann luftdicht sein^ sofern der Bereich (5) eine geschlossene Linie (Schweissnaht) bildet. Der innere Bereich (4) kann aber auch offen sein, wenn z. B. der Bereich (5) nur punktuell ausgebildet ist.The primary packaging comprises an upper packaging material web (3) and a lower packaging material web (2) which have areas (5) which are in intimate contact with one another. The fact that the packaging material bottom web (2) and the packaging material top web (3) are connected to one another results in a composite of the packaging material top web and the packaging material bottom web, which encloses an inner region (4) which is capable of receiving the sheet-like object. The inner area (4) can be airtight ^ as long as the area (5) forms a closed line (weld seam). The inner area (4) can but also be open if e.g. B. the area (5) is formed only selectively.
Der innige Kontakt in dem Bereich (5) wird vorzugsweise durch Heiss- oder Kaltsiegeln hergestellt. Die Stärke des Kontakts kann auf die Erfordernisse des flächenförmigen Gegenstands (1) und des benötigten Kraftaufwandes zum Öffnen eingestellt werden. Bevorzugt ist die Stärke dieses Kontakts so, dass eine Aufhebung dieses innigen Kontakts bei Anwendung einer von einer erwachsenen Person leicht aufzubringenden Zugkraft erfolgt, ohne dass dabei die einzelnen Packstoffbahnen zerstört werden. Der Fachmann bezeichnet diese Eigenschaft als peelfähig.The intimate contact in the area (5) is preferably made by heat or cold sealing. The strength of the contact can be adjusted to the requirements of the sheet-like object (1) and the effort required to open it. The strength of this contact is preferably such that this intimate contact is eliminated when a tensile force that can easily be applied by an adult is removed without the individual packaging material webs being destroyed in the process. The person skilled in the art describes this property as peelable.
Die Ausmasse des inneren Bereichs (4), der zur Aufnahme von mindestens einem flächenförmigen Gegenstand (1) befähigt ist, sind an die Ausmasse und die Form des zu verpackenden flächenförmigen Gebildes angepasst und im allgemeinen nur geringfügig grösser. Im inneren Bereich (4) besitzen die Packstoffbahnen keinen Kontakt zueinander. Auf der Packstoffbahn (2) entsteht somit im inneren Bereich (4) eine der Form des zu verpackenden flächenförmigen Gebildes angepasste Fläche ohne Kontakt zur Packstoffbahn (3), die in bevorzugten Ausführungsformen quadratisch, rechteckig, rund oder oval ist.The dimensions of the inner area (4), which is capable of receiving at least one sheet-like object (1), are adapted to the size and shape of the sheet-like structure to be packaged and are generally only slightly larger. In the inner area (4), the packaging material webs have no contact with one another. Thus, on the packaging material web (2), in the inner region (4), a surface is created which is adapted to the shape of the sheet-like structure to be packaged, without contact with the packaging material web (3), which in preferred embodiments is square, rectangular, round or oval.
Die Materialien der Packstoffbahnen (2, 3), welche im Rahmen der Herstellung einer erfindungsgemässen Primärverpackung zum Einsatz kommen können, sind die üblichen, zur Herstellung von Siegelbeuteln und Blisterverpackungen bekannten Stoffe. Hierzu zählen zum Beispiel Polyethylen (PE), Polyethylenterephthalat (PET), Polypropylen (PP), OPA, Polyacrylat (PA), EVOH, Ethylen-Vinylacetat-Copolymere (EVA), EC, Barex, Surlyn, Papier, Aluminium und Kombinationen dieser Stoffe.The materials of the packaging material webs (2, 3) which can be used in the production of a primary packaging according to the invention are the usual substances known for the production of sealing bags and blister packs. These include, for example, polyethylene (PE), polyethylene terephthalate (PET), polypropylene (PP), OPA, polyacrylate (PA), EVOH, ethylene-vinyl acetate copolymers (EVA), EC, Barex, Surlyn, paper, aluminum and combinations of these substances ,
Die Ober- bzw. Unterbahn können aber jeweils auch als Verbundwerkstoffe aus zwei oder mehreren Schichten der genannten Stoffe und ggf. weiterer Materialien aufgebaut sein. Auch können eine oder beide Bahnen als tiefgezogene Blisterbasis ausgelegt sein.However, the top and bottom webs can also each be used as composite materials made up of two or more layers of the materials mentioned and, if appropriate, more Materials. One or both webs can also be designed as a deep-drawn blister base.
Gekennzeichnet ist die erfindungsgemässe Primärverpackung dadurch, dass die Packstoffoberbahn (3) und die Packstoffunterbahn (2) jeweils mindestens einen Aussenbereich besitzen, der sich am Rande des Bereichs (5) befindet, in dem die Packstoffoberbahn und die Packstoffunterbahn in innigem Kontakt zueinander vorliegen. In diesen beiden Aussenbereichen besitzen die Packstoffoberbahn (3) und die Packstoffunterbahn (2) keinen Kontakt zueinander. Weiterhin sind sie so geformt, dass sie in der Primärverpackung nicht kongruent übereinanderliegen. Diese Tatsache ermöglicht es, dass man gleichzeitig mit einer Hand den Aussenbereich der Packstoffunterbahn (2) und mit der anderen Hand den Aussenbereich der Packstoffoberbahn (3) anfassen kann. Durch Anwendung einer entsprechenden Zugkraft kann so schliesslich die Verpackung bequem aufgerissen werden.The primary packaging according to the invention is characterized in that the packaging material top web (3) and the packaging material bottom web (2) each have at least one outer area which is located on the edge of the area (5) in which the packaging material top web and the packaging material bottom web are in intimate contact with one another. In these two outer areas, the upper packaging material (3) and the lower packaging material (2) have no contact with one another. Furthermore, they are shaped in such a way that they do not lie congruently one above the other in the primary packaging. This fact makes it possible to grasp the outer area of the lower packaging material (2) with one hand and the outer area of the upper packaging material (3) with the other hand. By using the appropriate pulling force, the packaging can finally be torn open.
In einer weiteren Ausführungsform kann die Primärverpackung mehrnutzig ausgestattet sein, z. B. mit 2, 5, 6 oder 10 parallel angeordneten einzelnen Primärverpackungen, die durch Sollbruchlinien (6), z. B. einer eingekerbten Linie oder einer Perforation, voneinander getrennt sind.In a further embodiment, the primary packaging can be equipped with multiple uses, e.g. B. with 2, 5, 6 or 10 arranged in parallel individual primary packaging, which by predetermined lines (6), z. B. a notched line or perforation are separated.
In einer weiteren Ausführungsform sind die Packstoffoberbahn (3) und die Packstoffunterbahn (2) unterschiedlich eingefärbt oder bedruckt.In a further embodiment, the packaging material top web (3) and the packaging material bottom web (2) are colored or printed differently.
Eine erfindungsgemässe Primärverpackung kann wie folgt hergestellt werden:A primary packaging according to the invention can be produced as follows:
Beispiel 1 : Herstellung einer PrimärverpackungExample 1: Production of a primary packaging
Zunächst wird eine Bahn, die als Packstoffunterbahn" dient, bereitgestellt und gegebenenfalls mit einer Kontur versehen. Diese wird vorzugsweise mittels rotativer Schneidewalze im Aussenbereich der Packstoffunterbahn eingestanzt. Anschliessend werden einzelne Wafer auf die Packstoffunterbahn gelegt. In einem darauf folgenden Schritt wird von einer Vorratsrolle die Packstoffoberbahn abgerollt und auf die mit den einzelnen Wafern versehenen Packstoffunterbahn geführt. Diese übereinander liegenden Bahnen werden in eine Konturpresse geführt, in der vorzugsweise eine geschlossene Kontur gestanzt wird. Hierdurch wird ein geschlossener innerer Bereich geschaffen, in dem sich der Wafer befindet. Nach Abgittern eines eventuell vorhandenen überstehenden Rands wird gegebenenfalls eine Perforation in den zwischen zwei einzelnen Primärverpackungen befindlichen Bereich eingeprägt. Schliesslich kann ein Vereinzeln der Primärverpackungen erfolgen.First of all, a web that serves as the “ lower packaging material ” is provided and optionally provided with a contour. This is preferably done by means of a rotating cutting roller in the outer region of the lower packaging material stamped. Subsequently, individual wafers are placed on the packaging base. In a subsequent step, the packaging material upper web is rolled off a supply roll and guided onto the packaging material lower web provided with the individual wafers. These superimposed webs are fed into a contour press, in which a closed contour is preferably punched. This creates a closed inner area in which the wafer is located. After a protruding edge that may be present has been trimmed off, a perforation may be embossed into the area between two individual primary packagings. Finally, the primary packaging can be separated.

Anhand der Figuren 1 bis 8 werden Ausführungsformen der erfindungsgemässen Primärverpackung für flächenförmige Gegenstände beschrieben.Embodiments of the primary packaging according to the invention for sheet-like objects are described with reference to FIGS. 1 to 8.
Figur 1 zeigt die Seitenansicht einer Primärverpackung nach dem Stand der Technik dar, bei der die Packstoffoberbahn (3) und die Packstoffunterbahn (2) kongruent übereinander liegen.FIG. 1 shows the side view of a primary packaging according to the prior art, in which the upper packaging material (3) and the lower packaging material (2) lie congruently one above the other.
Figur 2 zeigt drei unterschiedliche Ausführungsformen der erfindungsgemässen Primärverpackung in der Aufsicht, bei der die Packstoffoberbahn (3) und die Packstoffunterbahn (2) nicht kongruent übereinander liegen. Die Aussenbereiche der Packstoffunterbahn (2) ragen über den Aussenbereich der Packstoffoberbahn (3) hinaus. Die seitliche Aussenbegrenzung kann gerade oder oder als Bogen geschnitten sein.Figure 2 shows three different embodiments of the primary packaging according to the invention in supervision, in which the The upper packaging material (3) and the lower packaging material (2) are not congruently one above the other. The outer areas of the packaging material lower web (2) protrude beyond the outer area of the packaging material upper web (3). The lateral outer boundary can be cut straight or or as an arc.
Figur 3 zeigt eine Primärverpackung in fünfnutziger Ausführungsform. Die nicht-kongruente Überdeckung der Packstoffunterbahn (2) durch die Packstoffoberbahn (3) ist durch einen wellenförmigen Schnitt bedingt, der hinsichtlich Frequenz und Phase an die Breite der einzelnen Primärverpackung angepasst wurde. Die einzelnen Primärverpackungen sind durch Sollbruchlinien (6) voneinander getrennt.Figure 3 shows a primary packaging in five-use embodiment. The non-congruent coverage of the packaging material lower web (2) by the packaging material upper web (3) is due to a wavy cut, which was adjusted in frequency and phase to the width of the individual primary packaging. The individual primary packaging is separated from one another by predetermined breaking lines (6).
Figur 4 zeigt eine Primärverpackung in fünfnutziger Ausführungsform. Die nicht-kongruente Überdeckung der Packstoffunterbahn (2) durch die Packstoffoberbahn (3) ist durch einen wellenförmigen Schnitt bedingt, der hinsichtlich Frequenz an die Breite der einzelnen Primärverpackung angepasst, jedoch um eine halbe Wellenlänge verschoben ist.Figure 4 shows a primary packaging in five-use embodiment. The non-congruent coverage of the lower packaging material (2) by the upper packaging material (3) is due to a wavy cut, which is adjusted in frequency to the width of the individual primary packaging, but is shifted by half a wavelength.
Figur 5 zeigt eine Primärverpackung in fünfnutziger Ausführungsform. Die nicht-kongruente Überdeckung der Packstoffunterbahn (2) durch die Packstoffoberbahn (3) ist durch einen wellenförmigen Schnitt bedingt, dessen Wellenlänge der Breite von zwei einzelnen Primärverpackungen entspricht.Figure 5 shows a primary packaging in five-use embodiment. The non-congruent coverage of the lower packaging material (2) by the upper packaging material (3) is due to a wavy cut, the wavelength of which corresponds to the width of two individual primary packagings.
Figur 6 zeigt eine Primärverpackung in sechsnutziger Ausführungsform. Die nicht-kongruente Überdeckung der Packstoffunterbahn (2) durch die Packstoffoberbahn (3) ist durch einen geraden Schnitt bedingt, der am Bereich innigen Kontakts zwischen Packstoffoberbahn und Packstoffunterbahn einer ersten Primärverpackung beginnt und bis zum diagonal gegenüberliegenden Ende des Aussenbereichs verläuft. Figur 7 zeigt eine Primärverpackung wie in Fig. 6, jedoch mit einer nur einseitigen nicht-kongruenten Überdeckung der Packstoffunterbahn (2) durch die Packstoffoberbahn (3).Figure 6 shows a primary packaging in six-use embodiment. The non-congruent coverage of the lower packaging material (2) by the upper packaging material (3) is due to a straight cut that begins at the area of intimate contact between the upper packaging material and the lower packaging material of a first primary packaging and extends to the diagonally opposite end of the outer area. FIG. 7 shows a primary packaging as in FIG. 6, but with only one-sided non-congruent coverage of the packaging material lower web (2) by the packaging material upper web (3).
Figur 8 zeigt eine Primärverpackung mit einer einseitigen nicht-kongruenten Überdeckung der Packstoffunterbahn (2) durch die Packstoffoberbahn (3). Die seitliche Aussenbegrenzuπg beider Bahnen entspricht hier einem wellenförmigen Schnitt mit gleicher Frequenz. Die Versetzung um eine Phase der Packstoffoberbahn (3) gegenüber der Packstoffunterbahn (2) bewirkt die nicht-kongruente Überdeckung der beiden Bahnen. FIG. 8 shows a primary packaging with a one-sided, non-congruent covering of the lower packaging material (2) by the upper packaging material (3). The lateral outer boundary of both tracks corresponds to a wavy cut with the same frequency. The offset by one phase of the packaging material upper web (3) compared to the packaging material lower web (2) causes the non-congruent overlap of the two webs.
