Description

Die Erfindung betrifft eine Verpackung für Gegenstände, insbesondere von Quaderform, bestehend aus Folienmaterial das als eine im wesentlichen geschlossene Folienhülle den einzelnen und/oder mehrere Gegenstände relativ eng umschließt, wobei die Folienhülle mit Mitteln zur Aufreißhilfe versehen ist und die Folienhülle teilweise bedruckt ausgebildet und durch Verbinden von unbedruckten Flächen des Folienmaterials mittels Heißsiegelverfahrens hergestellt ist, sowie ein Folienzuschnittband für eine solche Verpackung und einen Gegenstand, insbesondere eine Bandkassette mit einer solchen Verpackung.The invention relates to a packaging for objects, in particular cuboid, consisting of film material which, as an essentially closed film envelope, surrounds the individual and / or several objects relatively closely, the film envelope being provided with means for tearing open and the film envelope being partially printed and formed by Connecting unprinted areas of the film material by means of the heat sealing process, and a film cutting tape for such packaging and an object, in particular a tape cassette with such packaging.

Mit dem DE-U-8715168 ist eine Folienverpackung mit aus einem Aufreißfaden bestehender Aufreißhilfe bekannt, wobei zusätzlich eine Perforation im Winkel zur und nahe der Trennlinie des Aufreißfadens vorgesehen ist, die ein Ein- und Aufreißen der Resthülle erleichtern soll. Aufwendig ist die Notwendigkeit eine Folie mit Aufreißfaden verwenden zu müssen sowie die zusätzliche Anbringung der Perforation. Bei dieser bekannten Verpackung handelt es sich um eine unbedruckte Klarsicht-Folienhülle z.B. aus Polypropylen.With DE-U-8715168 a film packaging with a tear-off aid consisting of a tear-off thread is known, wherein additionally a perforation at an angle to and near the dividing line of the tear-off thread is provided, which is intended to facilitate tearing and tearing open the remaining casing. The need to use a film with tear thread and the additional attachment of the perforation are complex. This known packaging is an unprinted transparent film cover, e.g. made of polypropylene.

Es sind aus bedrucktem Folienmaterial bestehende Folienhüllen für Magnetbandkassetten bekannt, die am Umriß mit nicht bedruckten (Siegel-)Randstreifen zum Heißsiegeln ausgebildet sind. Zum Erfassen des Aufreißfadens kann der Siegel-Randstreifen mit einer Aussparung versehen sein. Das Erfassen ist dennoch schwierig, da die Aussparung in der Regel sehr klein ist, um das optische Erscheinungsbild der verpackten Kassette möglichst wenig zu verändern, und da beim Siegelvorgang die Grifflasche des Aufreißfadens häufig mit festgesiegelt wird.There are known film covers for magnetic tape cassettes made of printed film material, which are formed on the outline with unprinted (sealing) edge strips for heat sealing. The sealing edge strip can be provided with a cutout for gripping the tear thread. It is nevertheless difficult to grasp, since the recess is generally very small in order to change the optical appearance of the packaged cassette as little as possible, and because the grip tab of the tear thread is often also sealed during the sealing process.

Die vorliegende Erfindung hat sich die Aufgabe gestellt, eine wirksame und kostengünstige Aufreißhilfe bereitzustellen, die es gestattet, auch die Resthülle bei, insbesondere mittels Polypropylenfolie, verschweißten Gegenständen, insbesondere Magnetbandkassetten, ohne Aufwand zu entfernen.The object of the present invention is to provide an effective and inexpensive tear-open aid which also makes it possible to remove the residual casing from objects, in particular magnetic tape cassettes, which are welded, in particular by means of polypropylene film, without any effort.

Die Aufgabe wird mit einer Verpackung für Gegenstände, insbesondere von Quaderform, bestehend aus Folienmaterial das als eine im wesentlichen geschlossene Folienhülle den einzelnen und/oder mehrere Gegenstände relativ eng umschließt, wobei die Folienhülle mit Mitteln zur Aufreißhilfe versehen ist, und die Folienhülle wenigstens teilweise bedruckt ausgebildet und durch Verbinden von unbedruckten Flächen des Folienmaterials mittels Heißsiegelverfahrens hergestellt ist, damit gelöst, daß die Mittel zur Aufreißhilfe als mindestens ein aus einem Teil der Folie bestehender Aufreißteil ausgebildet sind, der als Unterbrechung einer rahmenartigen, heißzuversiegelnden Folienfläche einen Aufdruck trägt und wenigstens in dessen Nähe mindestens eine Einreißlinie vorgesehen ist.The object is achieved with a packaging for objects, in particular cuboid, consisting of film material which, as an essentially closed film envelope, relatively closely encloses the individual and / or several objects, the film envelope being provided with means for tearing open, and at least partially printed on the film envelope formed and by connecting unprinted areas of the film material by means of Heat sealing process is produced, so that the means for the tear-open aid are designed as at least one tear-off part consisting of part of the film, which carries an imprint as an interruption of a frame-like, heat-sealable film surface and at least one tear line is provided in the vicinity thereof.

Damit wird das Auspackproblem bei wenigstens teilweise bedruckten, heißversiegelten Folienhüllen, das außer zu Beschädigungen des verpackten Gegenstandes auch zum Ärger des Auspackwilligen führen kann, auf überraschend einfache und sehr wirtschaftliche Weise gelöst. Insbesondere kann auf die Verwendung von Aufreißfäden oder -streifen völlig verzichtet werden. Außerdem besitzt die Verpackung vor dem Aufreißvorgang ein ordentliches Erscheinungsbild ohne Aufrollen von Folienteilen usw..This solves the unpacking problem in at least partially printed, heat-sealed film sleeves, which in addition to damage to the packaged item can also lead to the annoyance of the person unwilling to unpack, in a surprisingly simple and very economical manner. In particular, the use of tear threads or strips can be dispensed with entirely. In addition, the packaging has a neat appearance before the tearing process without rolling up film parts, etc.

In weiterer Ausbildung der Erfindung kann zweckmäßig neben dem Aufreißteil eine im Winkel zu einer Einreißlinie verlaufende Grenzlinie einer Bedruckung vorgesehen und die Folienfläche hinter der Grenzlinie unbedruckt sein.In a further embodiment of the invention, in addition to the tear-open part, a border line of printing that runs at an angle to a tear line can expediently be provided and the film surface behind the border line can be unprinted.

Dadurch wird es einfach möglich, ohne weitere Maßnahmen eine gewünschte und wirksame Aufreißrichtung vorzugeben, ohne daß ein spezieller Aufreiß- oder Öffnungshinweis an der Verpackung erforderlich ist.This makes it easy to specify a desired and effective tear direction without further measures, without the need for a special tear or opening instruction on the packaging.

In zweckmäßiger Ausführung der Erfindung können zwei Aufreißteile an der Folienhülle im wesentlichen übereinander angeordnet sein, so daß es möglch ist, einem ersten Aufreißversuch einen zweiten, erfolgreicheren folgen zu lassen.In an expedient embodiment of the invention, two tear-open parts on the film envelope can be arranged essentially one above the other, so that it is possible to have a second, more successful attempt to follow a first tear open.

In weiterer Ausgestaltung kann der Aufdruck und/oder die Bedruckung auf beiden Aufreißteilen vorgesehen sein.In a further embodiment, the printing and / or the printing can be provided on both tear-open parts.

Besonders vorteilhaft ist die erfindungsgemäße Lösung im Falle, daß das Folienmaterial Polypropylen-Folie ist, die besonders fest und zäh geartet ist und die üblicherweise nur nach Einschneiden oder -ritzen einreißbar und damit entfernbar ist, was wiederum das Vorhandensein eines Werkzeugs voraussetzt.The solution according to the invention is particularly advantageous in the case that the film material is polypropylene film, which is particularly strong and tough and which can usually only be torn or cut after cutting or scratching, which in turn presupposes the presence of a tool.

Der Winkel der Grenzlinie sollte im Bereich von β etwa 80° bis ca. 10° zur Einreißlinie angeordnet sein.The angle of the boundary line should be in the range of about 80 ° to about 10 ° to the tear line.

Zweckmäßig kommt die Verpackungsart für ein Folienmaterial zur Verwendung, dessen Zugfestigkeit oder Reißfestigkeit der Folie im Bereich von etwa 120 bis 180 N/mm² in Längsrichtung und von ca. 140 N/mm² bis ca. 240 N/mm² in Querrichtung beträgt.The type of packaging is expediently used for a film material whose tensile strength or tear strength of the film is in the range from approximately 120 to 180 N / mm² in the longitudinal direction and from approximately 140 N / mm² to approximately 240 N / mm² in the transverse direction.

Ein Folienzuschnittband für eine erfindungsgemäße Verpackung ist zweckmäßig so ausgebildet, daß der Aufdruck des Aufreißteils jeweils zwischen zwei zusammenhängenden Folienzuschnitten, die jeweilige Trennlinie zwischen den zwei Folienzuschnitten übergreifend, angeordnet ist.A film cutting tape for a packaging according to the invention is expediently designed such that the imprint of the tear-open part is arranged between two contiguous film cuts, spanning the respective dividing line between the two film cuts.

Der Gegenstand mit der erfindungsgemäße Verpackung, z.B. eine oder mehrere Bandkassetten gewinnen durch die Erfindung deutlich an Gebrauchswert. Vorteilhaft ist eine Bandkassette mit einer Verpackung, deren Folienmaterial aus einer Polypropylenfolie mit einer Stärke von 15 bis 40 µm, vorzugsweise von 30 µm besteht.The article with the packaging according to the invention, e.g. one or more tape cassettes gain significantly in use value by the invention. A tape cassette with a packaging is advantageous, the film material of which consists of a polypropylene film with a thickness of 15 to 40 μm, preferably of 30 μm.

Figur 1 zeigt zwei Verbindungsstellen (7, 8) zwischen drei Folienzuschnitten 5' für Bandkassetten. Mit 11 sind die Trennlinien zwischen den Einzelzuschnitten 5' bezeichnet, die üblicherweise beim oder nach dem Verpackungsvorgang mittels einer Trennvorrichtung durchgetrennt werden. Jeder Zuschnitt 5' besteht aus dem zwischen den Trennlinien (11) liegenden äußeren Umrißlinien, er setzt sich somit zusammen aus einer bedruckten Fläche 5 und Heißsiegelzonen 10, die rahmenartig, bis auf eine Stelle (7, 8), die bedruckte Fläche 5 umgeben. An besagter Stelle im Bereich jeder Trennlinie 11 sind für die noch aneinanderhängendenh Zuschnitte 5' die Aufreißhilfen in Form von Aufreißteilen 7 (7A und 7B sind die oberen und unteren Aufreißteile) vorgesehen, die zu einem Zuschnitt 5' gehören. Gebildet sind diese Aufreißteile 7 durch je einen Aufdruck 8 auf eben der Folienfläche, die zum Heißsiegeln mittels eines Siegelstempels vorgesehen ist.Figure 1 shows two connection points (7, 8) between three film blanks 5 'for tape cassettes. With 11 the dividing lines between the individual blanks 5 'are designated, which are usually severed during or after the packaging process by means of a separating device. Each blank 5 'consists of the outer contour lines between the dividing lines (11), it is therefore composed of a printed one Surface 5 and heat-sealing zones 10, which frame-like, except for one place (7, 8), surround the printed surface 5. At the said point in the area of each dividing line 11, the tear-open aids in the form of tear-open parts 7 (7A and 7B are the upper and lower tear-off parts), which belong to a blank 5 ', are provided for the blanks 5' which are still attached to one another. These tear-open parts 7 are each formed by an imprint 8 on the surface of the film which is intended for heat sealing by means of a sealing stamp.

In diesem Beispiel einer Bandkassettenverpackung liegt die Bedruckung auf der Innenseite der Folie, die der Kassette zugewandt ist.In this example of a tape cassette packaging, the printing is on the inside of the film facing the cassette.

Wie die Beispiele der Figur 1 und der Einzelheit "A" zeigen, besteht der Aufdruck 8, 8' aus einem Aufreißhinweis mit je einem Pfeil, der die empfohlene Aufreißrichtung angibt. In beiden Darstellungen ist auch erkennbar, daß neben dem Rechteck-Aufreißhinweis (Aufdruck 8, 8') eine weitere Bedruckung vorhanden ist, die mit einer schrägen Grenzlinie 12 (Winkel β etwa im Bereich von ca. 10 bis 80°) gegenüber der unbedruckten Siegelzone 10 endet. Diese Bedruckung, deren Art völlig beliebig ist, bewirkt, daß nach Heißsiegeln die Schräglinie 12 gleichzeitig die Verbindungsgrenze zwischen den verschmolzenen Folienflächen darstellt. Mit 9 ist einseitig insbesondere gerade innerhalb des Aufdrucks 8 in der Längsrichtung eine Einreißlinie vorgesehen, die zum Einleiten des Aufreißvorganges dient. In weiterer Ausführung könnte in Richtung der Grenzlinie 12 ebenfalls im wesentlichen innerhalb des Aufdrucks 8 eine weitere Einreißlinie vorgesehen werden.As the examples in FIG. 1 and the detail "A" show, the print 8, 8 'consists of a tear-open notice with an arrow each, which indicates the recommended tear-open direction. In both representations it can also be seen that, in addition to the rectangular tear-open notice (imprint 8, 8 '), there is further printing which has an oblique border line 12 (angle β approximately in the range of approximately 10 to 80 °) with respect to the unprinted sealing zone 10 ends. This printing, the type of which is completely arbitrary, has the effect that after heat sealing, the oblique line 12 simultaneously represents the connection boundary between the fused film surfaces. With 9, a tear line is provided on one side, especially within the imprint 8 in the longitudinal direction, which serves to initiate the tear process. In a further embodiment, a further tear line could also be provided in the direction of the boundary line 12, essentially within the imprint 8.

In den weiteren Ausführungsbeispielen wird von einer einzigen senkrechten Einreißlinie 9 ausgegangen.In the further exemplary embodiments, a single vertical tear line 9 is assumed.

Figur 2 zeigt beispielsweise eine Kompaktkassette in einer üblichen Kassettenbox mit einer bedruckten Kassettenverpackung, die auf der langen Schmalseite den (oberen) Aufreißteil 7A sowie die Schägbedruckung (Grenzlinie 12) mit einem Winkel β von etwa 45° erkennen läßt.FIG. 2 shows, for example, a compact cassette in a conventional cassette box with a printed cassette packaging, which shows the (upper) tear-open part 7A and the oblique printing (boundary line 12) with an angle β of approximately 45 ° on the long narrow side.

Einzelheit "B" zeigt eine teilweise aufgerissene Lasche 22, die durch die Einrißlinie 9 und die Grenzlinie 12 (Figur 2) in ihrer Form bestimmt ist. Die Aufreißrichtung ist mit Pfeil 21 bezeichnet und außer dem oberen Aufreißteil 7a ist der untere, nunmehr freigelegte Aufreißteil 7B sichtbar. Figur 2A zeigt nun den Fall, daß der Aufreißvorgang zwar weitergeführt wurde, aber nur ein Folienabriß erfolgte, was als Abriß-Aussparung 16 erkennbar ist. Der untere Aufreißhinweis 7B wurde dabei vollständig freigelegt, so daß mittels des unteren Aufreißzipfels 19 jetzt ein Abreißen, wie in Figur 2B anhand der Kassettenverpackung 15 dargestellt, in Abreißrichtung 23 erfolgen kann, wodurch die Restverpackung nunmehr völlig entfernbar ist.Detail "B" shows a partially torn tab 22, the shape of which is determined by the tear line 9 and the border line 12 (FIG. 2). The direction of tear-open is indicated by arrow 21 and, apart from the upper tear-open part 7a, the lower, now exposed tear-open part 7B is visible. FIG. 2A now shows the case in which the tearing process was continued, but only a film tear occurred, which can be seen as a tear-out cutout 16. The lower tear-open indication 7B was completely exposed, so that a tear-off, such as shown in FIG. 2B using the cassette packaging 15, can take place in the tear-off direction 23, as a result of which the remaining packaging can now be removed completely.

Figur 3 zeigt die Mehrkassettenverpackung 15 mit oberem Aufreißteil 7A und Heißsiegelzone 10, die sich beispielsweise auf der Schmalseite 20 fortsetzen kann. Mit 17 ist ein Sichtfeld innerhalb der bedruckten Folienhülle bezeichnet.FIG. 3 shows the multi-cassette packaging 15 with an upper tear-open part 7A and a heat-sealing zone 10, which can continue, for example, on the narrow side 20. With 17 a field of view is designated within the printed film envelope.

Beim Aufreißvorgang-Einreißen am nicht angesiegelten oberen Aufreißzipfel 18 (der auch als Lasche ähnlich 22 in Figur 2, Einzelheit "B" ausgebildet ist, und Aufreißen in Richtung des Pfeils 21 - kann die gesamte Folienhülle ohne Rest von der oder den Kassetten abgelöst werden, so daß diese dem Benutzer zugänglich werden. Im Falle eines Folienabrisses kann die dann notwendige, vollständige Entfernung der Restverpackung auch gemäß Figur 3B wie bereits oben beschrieben mittels des Reserve-Aufreißteils 7B (am unteren Aufreißzipfel 19) erfolgen.When tearing open the unsealed upper tear-off tab 18 (which is also designed as a tab similar to 22 in FIG. 2, detail "B", and tearing open in the direction of arrow 21), the entire film cover can be detached from the cassette or cassettes without any residue, In the event of a film tear, the then necessary, complete removal of the residual packaging can also take place according to FIG. 3B, as already described above, by means of the reserve tear-open part 7B (on the lower tear-off tip 19).

Die Breite der Lasche 22 bzw. des Aufreißzipfels 18 ist vorteilhaft einer normalen Fingerbreite (ca. 1 cm) angepaßt.The width of the tab 22 or the tear-open tip 18 is advantageously adapted to a normal finger width (approx. 1 cm).

Die darin beschriebene biaxial gestreckte Folie besitzt eine relativ hohe Reiß- bzw. Zugfestigkeit von 150 N/mm² in Längs- und 220 N/mm² in Querrichtung. Die Folien, bei denen eine Verwendung der vorliegenden Erfindung notwendig ist, sind jedoch generell durch eine Zugfestigkeit von etwa 120 bis etwa 180 N/mm² längs und von ca. 140 bis 240 N/mm2 charakterisiert. Es ist als weitere physikalische Eigenschaft die Kanteneinreißkraft (z.B. im Einreißversuch nach DIN 7734 (Okt. 1958) bestimmt) und in der DIN 40 334 für Isolierfolien angegeben, maßgebend. Die Kanteneinreißkraft soll bei der Folie, womit die Erfindung verwendbar ist, mindestens 150 N betragen und vorzugsweise im Bereich von ca. 150 N bis 250 N liegen.The film material of the packaging examples described is e.g. Polypropylene film, e.g. Bicor® MB400 (® is a registered trademark of Mobil Oil Corporation), technical data sheet 6 404/4/86 of Mobil Plastics Europe. The biaxially stretched film described therein has a relatively high tear or tensile strength of 150 N / mm² in the longitudinal direction and 220 N / mm² in the transverse direction. However, the films in which use of the present invention is necessary are generally characterized by a tensile strength of about 120 to about 180 N / mm² lengthways and of about 140 to 240 N / mm2. As a further physical property, the edge tear force (e.g. determined in the tear test according to DIN 7734 (October 1958)) and specified in DIN 40 334 for insulating films is decisive. The edge tear force in the film, with which the invention can be used, should be at least 150 N and preferably be in the range from approximately 150 N to 250 N.

Die für die Verpackung von Bandkassetten verwandte Polypropylenfolie hatte eine Stärke zwischen ca. 15 µm und 40 µm, vorzugsweise 30 µm.The polypropylene film used for the packaging of tape cassettes had a thickness between approx. 15 µm and 40 µm, preferably 30 µm.

Die Verpackung kann gleichermaßen für einen oder mehrere Körper verwendet werden, die dann gemeinsam Quader- oder Rollenform haben können.The packaging can equally be used for one or more bodies, which can then have a cuboid or roll shape.

Die Verwendung der Erfindung ist nicht auf Verpackungen aus Polypropylenfolien beschränkt. Andere für Verpackungen dieser Art geeignete Folien aus anderem Material, z.B. PVC, Polyethylen, mit ähnlichen Festigkeits- und Zähigkeitscharakteristiken kommen für die Verwendung der erfindungsgemäßen Verpackungen mit doppelter Aufreißeinrichtung ebenfalls in Frage.The use of the invention is not limited to packaging made of polypropylene films. Other films of other material suitable for packaging of this type, e.g. PVC, polyethylene, with similar strength and toughness characteristics can also be used for the packaging according to the invention with a double tear-open device.

Die Vorzüge der Erfindung wurden durch zehn Personen anhand gleicher Anzahlen von mittels Polypropylenfolie verpackten Bandkassetten (Kompaktkassetten) getestet, ohne daß die Personen vorher über die Maßnahme der Erfindung informiert wurden. Im Ergebnis konnten nur die mit der Perforation versehenen Kompaktkassetten geöffnet werden trotz vielfältiger Bemühungen. Werkzeuge waren dabei nicht erlaubt.The advantages of the invention were tested by ten people using the same number of tape cassettes (compact cassettes) packed by means of polypropylene film, without the people having been informed beforehand about the measure of the invention. As a result, only the compact cassettes provided with the perforation could be opened despite various efforts. Tools were not allowed.
