The packaging is also provided with a label whose side facing the weld seam is configured as a curved tearing edge which is suited for intercepting a tear, said tear starting from the tearing aid, and for guiding the same to the edge of the packaging.

Description

Die Erfindung betrifft eine Schlauchverpackung, die insbesondere für Lebensmittel in stückiger oder portionierter Form geeignet ist und das jeweilige Produkt in einem zugeschweißten Kunststoffschlauch enthält.The invention relates to a hose packaging, in particular for Food in lumpy or portioned form is suitable and the respective Contains product in a welded plastic tube.

Schlauchverpackungen sind zur Verpackung von Lebens- und Genußmitteln weithin üblich. Dies trifft insbesondere für Lebensmittel in stückiger oder kleinteiliger Form zu, die dazu bestimmt sind, portionsweise verbraucht zu werden, sei es als Grundnahrungsmittel, Zutat zur Zubereitung von Speisen oder als Snack zum direkten Genuß. Schlauchverpackungen sind einfach herzustellen und zu befüllen, gut zu lagern und handzuhaben, ein guter Schutz für das darin verpackte Lebensmittel und erlauben die Kennzeichnung des Lebensmittels entweder unmittelbar auf dem Folienschlauch oder durch Aufkleber. Den hygienischen Anforderungen wird in vollem Umfang Rechnung getragen.Hose packaging is for packaging food and luxury food widely used. This is especially true for food in lumpy or small-part form, which are intended to be consumed in portions be it, as a staple food, ingredient for the preparation of dishes or as a snack for direct enjoyment. Hose packaging is easy to manufacture and to fill, to store well and to handle, a good protection for the food packed in it and allow the labeling of the Food either directly on the film tube or through Sticker. The hygienic requirements are fully taken into account carried.

Schlauchverpackungen bestehen in der Regel aus einem Folienschlauch, dessen beiden Enden durch Verkleben oder Verschweißen versiegelt sind. Die Ware ist auf diese Art und Weise optimal vor Umwelteinflüssen geschützt. Zum Entnehmen der Ware muß die Verpackung aufgerissen oder aufgeschnitten werden. Sofern keine Schere zur Hand ist, bleibt nur das Aufreißen, das in der Regel von einer der zugeschweißten Seiten her erfolgt. Vielfach sind dazu Aufreißhilfen vorhanden, beispielsweise in Form eines eingearbeiteten Aufreißfadens oder einer Kerbung, die als Ansatzpunkt für den Aufreißvorgang dient. Aber selbst dann ist der Aufreißvorgang häufig nicht zu steuern, so daß die Schlauchverpackung unkontrolliert über mehr als die gewünschte Länge aufreißt. Es kann davon ausgegangen werden, daß in vielen, wenn nicht in der Mehrzahl der Fälle der Aufreißvorgang nicht zu einer Öffnung führt, die die jeweils angestrebte Größe hat. Die Folgen können insbesondere bei flüssigem Inhalt unangenehm sein.Hose packaging usually consists of a film tube, both ends of which are sealed by gluing or welding. The In this way, goods are optimally protected against environmental influences. To the The packaging must be torn open or cut open to remove the goods become. If no scissors are at hand, all that remains is the tearing open in the Usually done from one of the welded sides. Often there are Rip aids are available, for example in the form of an integrated one Tear thread or a notch that serves as a starting point for the tear process serves. But even then the tearing process can often not be controlled, so that the hose packaging is uncontrolled over more than the desired length tears. It can be assumed that in many, if not the Most of the cases of tearing open do not lead to an opening that has the desired size. The consequences can be particularly with liquid Content may be uncomfortable.

Aufrißführungen in Form eines in die Verpackung integrierten Lineals sind für Kunststofftüten vorgeschlagen worden. Hierdurch wird aber ein kontrollierter Aufriß nicht ermöglicht; vielmehr wandert der Riß aus.Rip guides in the form of a ruler integrated in the packaging are for Plastic bags have been proposed. This will make it a controlled one Elevation not possible; rather the crack migrates.

Sofern der Inhalt der Verpackung zum sofortigen Verbrauch bestimmt ist, ist dies eher unproblematisch. Problematisch sind die Fälle, in denen der Verpackung nur ein Teil der Ware entnommen und verbraucht werden soll, der Rest jedoch in der Verpackung aufbewahrt und gelagert werden soll. Hier ist eine relativ kleine Öffnung gewünscht, die auf die Stückgröße des Packungsinhalts ausgerichtet ist. Eine solche Öffnung abgestimmter Größe ist auch aus hygienischen Gesichtspunkten erstrebenswert. Andererseits darf aber die Öffnung aus Handhabungsgründen nicht zu klein ausfallen.If the content of the packaging is intended for immediate consumption, this is rather unproblematic. The cases in which the Packaging only a part of the goods should be removed and consumed The rest, however, should be kept in the packaging and stored. Here is wanted a relatively small opening, based on the size of the piece Package content is aligned. Such an opening is of a coordinated size Also desirable from a hygienic point of view. On the other hand, however the opening is not too small for handling reasons.

WO-A-90/11946 beschreibt eine Verpackung mit einer Aufrißhilfe und einem dar unter angeordneten Aufkleßer in Form eines Winkels, des sich um die Seitenkante herum auf beide Seiten des Verpackung erstreckt.WO-A-90/11946 describes a package with a tear aid and one under arranged sticker in the form of a Angle, which is around the side edge on both sides of the packaging extends.

Aufgabe der Erfindung ist somit die Bereitstellung einer Schlauchverpackung, die die Herstellung einer Öffnung definierter und auf die Stückgröße der darin verpackten Lebensmittel ermöglicht. Die Öffnung soll ohne äußere Hilfsmittel durch Aufreißen mit der Hand zuverlässig hergestellt werden können und die Verpackung soweit in Takt lassen, daß die Lagerung der Restmenge darin enthaltener Produkte ohne weiteres möglich ist.The object of the invention is therefore to provide a hose packaging, which defines the creation of an opening and the size of the pieces in it packaged food. The opening should be without external aids can be reliably produced by tearing by hand and the Leave the packaging intact enough to store the remaining amount in it contained products is easily possible.

Diese Aufgabe wird mit einer Verpackung der eingangs genannten Art gelöst, die im Bereich einer Schweißnaht eine Aufreißhilfe aufweist und mit einem Aufkleber versehen ist, dessen der Schweißnaht zugewandte Seite als gekrümmte Abrißkante ausgebildet ist, die geeignet ist, einen Riß, der von der Aufreißhilfe ausgeht, aufzufangen und zum Rand der Verpackung zu führen. Die Abrißkante hat einen S-förmigen Verlauf oder wird von einem viertelkreisförmigen Ausschnitt des Aufklebers gebildet und läuft im wesentlichen senkrecht auf den Rand der Verpackung zu.This object is achieved with packaging of the type mentioned at the outset, which has a tear aid in the area of a weld seam and with a Sticker is provided, the side facing the weld as curved tear-off edge is formed, which is suitable for a tear, which of the Tear aid goes out to catch and lead to the edge of the packaging. The The tear-off edge has an S-shaped course or is of a quarter circle Cutout of the sticker formed and runs in the essentially perpendicular to the edge of the packaging.

Die erfindungsgemäße Schlauchverpackung ist besonders für Lebensmittel geeignet, die zum Verzehr unterwegs bestimmt sind. Dies sind beispielsweise Schokoladen-, Müsli-, Gemüse- oder Fruchtriegel, die als "kleine Mahlzeit" für Reisen, als Pausensnack in der Schule oder auch als "Energielieferant" bei Prüfungen, Besprechungen oder generell als Zwischenmahlzeit bei der Arbeit geschätzt sind. In Frage kommen aber auch übliche Snacks, wie Nüsse, Erdnüsse, Chips, Flips, Gebäck, Bonbons und dergleichen, die dazu bestimmt sind, in kleinen Portionen oder Stückzahlen verzehrt zu werden, wobei der Rest zuverlässig in der bereits geöffneten Verpackung zurückgehalten werden soll. Schließlich ist die Aufreißhilfe aber auch für Verpackungen mit Flüssigkeiten oder Verbrauchsartikeln geeignet. Sie ist keinesfalls nur für den Lebensmittelbereich geeignet.The hose packaging according to the invention is particularly suitable for food suitable for consumption on the go. These are, for example Chocolate, muesli, vegetable or fruit bars that serve as a "small meal" for Travel, as a snack at school or as an "energy supplier" Exams, meetings or generally as a snack at work are appreciated. Common snacks, such as nuts, Peanuts, chips, flips, pastries, candies and the like that are destined for it are to be consumed in small portions or quantities, with the rest should be reliably retained in the already opened packaging. Finally, the tear aid is also for packaging with liquids or consumables. It is by no means only for him Suitable for the food sector.

Die erfindungsgemäße Verpackung ist besonders geeignet in Zusammenwirkung für eine Verpackung gemäß DE-GM 297 15 892, welche dazu bestimmt ist, mit einem Befestigungsmittel an einem Gegenstand an oder in diesen eingeheftet zu werden.The packaging according to the invention is particularly suitable in Cooperation for a packaging according to DE-GM 297 15 892, which is intended to be attached to an object with a fastener to be pinned into these.

Bei der erfindungsgemäßen Schlauchverpackung handelt es sich um eine besonders gestaltete übliche Verpackung, bei der die beiden Schlauchenden über eine Schweiß- oder Klebenaht zugesiegelt sind. Bei einer solchen Schlauchverpackung ist nun ein Aufkleber vorgesehen, der auf einer seiner der Schweißnaht zugewandten Seiten eine gekrümmte Abrißkante aufweist. Es versteht sich, daß der Aufkleber aus einem hinreichend rißbeständigen Material, insbesondere Kunststoff oder Papier besteht. Damit diese Abrißkante ihre bestimmungsgemäße Funktion übernehmen kann, befindet sich an der Verpackung im Bereich der Schweißnaht in einem Bereich direkt angrenzend an und zulaufend auf die Abrißkante eine Aufreißhilfe, beispielsweise in Form einer Einkerbung oder eines Einschnitts. Diese Aufreißhilfe reicht naturgemäß nicht bis in das Innere der Verpackung hinein, sondern endet noch im verschweißten Bereich. Viele Schlauchverpackungen weisen im Bereich ihrer Versiegelungsnähte eine Zähnung oder Riffelung auf, die ohne weiteres als Aufrißhilfe dienen kann. In diesem Fall ist es zweckmäßig, einen geeigneten Ansatzpunkt farblich zu markieren.The hose packaging according to the invention is a specially designed custom packaging in which the two hose ends are sealed with a weld or adhesive seam. With one Hose packaging is now provided a sticker on one of its Sides facing the weld seam have a curved tear-off edge. It it goes without saying that the sticker is made of a sufficiently crack-resistant material, in particular plastic or paper. So that tear-off edge yours intended function can be found on the Packaging in the area of the weld seam in an area directly adjacent to and running towards the tear-off edge, such as a tear-open aid Indentation or incision. This tear aid is naturally not enough to the inside of the packaging, but still ends in the welded Area. Many hose packaging show in the area of their Sealing seams have a serration or corrugation that is easily considered Breakdown aid can serve. In this case it is advisable to choose a suitable one Mark the starting point in color.

Die Aufreißhilfe befindet sich, bei aufrecht gehaltener Verpackung - mit der Schweißnaht am oberen Ende - oberhalb der gekrümmten Abrißkante des Aufklebers. Der Aufkleber ist dabei in einem verhältnismäßig geringem Abstand zur Schweißnaht angeordnet, beispielsweise in einem Abstand von 0,2 bis 5 cm. Der Abstand hängt dabei von der Größe der Verpackung und des Aufklebers sowie von der Länge der Abrißkante ab und von der Größe der in der Verpackung herzustellenden Öffnung.The tear-open aid is located with the packaging upright - with the Weld seam at the top - above the curved tear-off edge of the Sticker. The sticker is at a relatively short distance arranged to the weld, for example at a distance of 0.2 to 5 cm. The distance depends on the size of the packaging and the Stickers as well as the length of the tear-off edge and the size of the opening of the packaging.

Die Abrißkante nimmt einen gekrümmten Verlauf und ist geeignet, einen von der Aufreißhilfe ausgehenden Riß aufzufangen und zum Rand der Verpackung zu führen. Insbesondere führt die Abrißkante den Riß senkrecht auf den Rand zu. Der gekrümmte Verlauf stellt dabei sicher, daß Abrißkante und Rißverlauf immer in einem günstigen spitzen Winkel zueinander stehen. Ein Auswandern des Risses aus dem vorgesehenen Verlauf tritt nicht auf.The tear-off edge takes a curved course and is suitable for one of to catch the tear opening and to the edge of the packaging respectively. In particular, the tear-off edge leads the tear perpendicular to the edge to. The curved course ensures that the tear-off edge and crack course always stand at a favorable acute angle to each other. An emigration the crack from the intended course does not occur.

Gemäß einer bevorzugten Ausführungsform kann der Aufkleber um den Rand der Verpackung herumgeführt werden, wobei es zweckmäßig ist, daß er auf deren Rückseite deckungsgleich zur Frontseite verläuft. Diese Variante ist insbesondere auch bei Verpackungen mit seitlichen Falzen zweckmäßig.According to a preferred embodiment, the sticker can be around the edge the packaging are carried around, where it is appropriate that it on the back of which is congruent with the front. This variant is Especially useful for packaging with side folds.

Ein um den Rand der Schlauchfolienverpackung herumgeführter Aufkleber, insbesondere in Streifenform, trägt in hohem Maße zur Stabilisierung der Verpackung im Öffnungsbereich bei. Dies ermöglicht die Verwendung dünnerer Folien bzw. von Folien aus anderen, weniger rißbeständigen Materialien.A sticker wrapped around the edge of the tubular film packaging, especially in strip form, contributes to a great extent to stabilize Packaging in the opening area at. This enables the use of thinner ones Films or films made from other, less crack-resistant materials.

Erfindungsgemäß weist die Abrißkante einen S-förmigen und bevorzugt einen sinuskurvenförmigen Verlauf auf, wobei sich die Kurve im oberen Bereich, d. h. im an die Schweißnaht angrenzenden Bereich an den Aufkteberrand anschmiegt und mit dem anderen Ende auf einen angrenzenden Seitenrand des Aufklebers zuläuft. Die Amplitude einer solchen sinuskurvenförmigen Gestaltung der Abrißkante entspricht dabei zweckmäßigerweise 10 bis 20% der Länge der Kurve. Die Kurve verläuft insbesondere um eine Achse, die die Ränder des Aufklebers in einem Winkel α von 120 bis 150°, insbesondere 135° schneidet. Ein Schnittwinkel von 135° mit beiden Aufkleberrändem definiert dabei, bezogen auf das von der Achse und den fortgefallenen Schenkeln des Aufklebers gebildete Dreieck, ein gleichschenkliges Dreieck.According to the tear-off edge has an S-shaped and preferred a sinusoidal curve, with the curve in the upper area, d. H. in the area adjacent to the weld seam on the edge of the overprint hugs and with the other end on an adjacent side edge of the sticker comes up. The amplitude of such a sinusoidal curve Design of the tear-off edge suitably corresponds to 10 to 20% of the Length of the curve. The curve runs in particular around an axis that the Edges of the sticker at an angle α of 120 to 150 °, in particular 135 ° cuts. A cutting angle of 135 ° defined with both sticker edges here, based on that of the axis and the dropped legs of the Sticker formed triangle, an isosceles triangle.

Die S-förmige Kurve, die sich an den oberen Rand bzw. die der Schweißnaht zugewandten Seite des Aufklebers anschmiegt, endet auf der daran angrenzenden Seite etwa im rechten Winkel zum Rand.The S-shaped curve that is at the top or that of The side of the sticker that faces the weld seam clings to the end of it adjacent page at approximately a right angle to the edge.

Gemäß einer weiteren Variante wird die Abrißkante von einem etwa viertelkreisförmigen Ausschnitt im Eckbereich des Aufklebers gebildet.According to a further variant, the tear-off edge is approximately one quarter-circular cutout formed in the corner area of the sticker.

Bei dem Aufkleber kann es sich durchaus um ein übliches Etikett handeln, daß an dem der aufzureißenden Seite zugewandten Rand die entsprechende Gestaltung aufweist. Alternativ kann es sich aber auch um einen entsprechend gekrümmten Streifen Papier oder Kunststoff handeln, der keine weiteren Funktionen erfüllt. Bei Verwendung transparenter Kunststoffolie ist der Aufkleber auf der Verpackung selbst kaum wahrnehmbar. Ein Bedrucken ist ebenfalls möglich.The sticker can be a common label that on the edge facing the tear-open side, the corresponding one Design. Alternatively, it can also be a corresponding one curved strips of paper or plastic that are no other Functions fulfilled. When using transparent plastic film is the Barely noticeable sticker on the packaging itself. There is printing also possible.

Bei der Aufreißhilfe handelt es sich beispielsweise um eine Einkerbung in der Schweißnaht. Es kann sich dabei auch um eine Vielzahl von Einkerbungen handeln, wie sie als gezackter Rand bei derartigen Folienschlauchverpackungen zu finden sind. In diesem Fall kann es sinnvoll sein, eine besonders günstig zur Abrißkante gelegene Einkerbung zu markieren, beispielsweise durch eine farbliche Gestaltung. Geeignet sind auch eingeschweißte übliche Aufreißfäden.The tear aid is, for example, a notch in the Weld. It can also involve a variety of notches act as a jagged edge in such tubular film packaging can be found. In this case, it can be useful to have one to mark a notch that is particularly favorable to the tear-off edge, for example with a color scheme. Are also suitable welded usual tear threads.

Die Erfindung betrifft schließlich einen Aufkleber bzw. ein Etikett, das für die vorstehend beschriebene Schlauchverpackung die Funktion als Aufreißkante übernehmen kann und den vorstehenden Definitionen entspricht. Schließlich betrifft die Erfindung auch derartig gestaltete Schlauchverpackungen mit darin befindlicher Ware, bei der es sich auch um solche handeln kann, die nicht für den Lebensmittelbereich bestimmt ist, beispielsweise Düngemittel-, Waschmittel- oder Spülmitteltabletten bzw. -tabs.Finally, the invention relates to a sticker or a label for the The hose packaging described above has the function of a tear-open edge can take over and corresponds to the above definitions. Finally The invention also relates to tubular packaging designed in this way goods, which can also be those that are not for the food sector is determined, for example fertilizer, Detergent or dish soap tablets or tablets.

Figur 1 zeigt eine bevorzugte Ausführungsform einer erfindungsgemäßen Schlauchverpackung mit einem darauf angeordnete Etikett. Die Schlauchverpackung 1 selbst besteht aus einem Folienschlauch, der an seinen beiden Enden über Schweißnähte oder Klebenähte 2 versiegelt ist. Es versteht sich, daß unter dem hier verwandten Begriff "Schweißnaht" auch andersartige Versiegelungen zu verstehen sind, etwa Klebenähte. Auf der Schlauchverpackung befindet sich das Etikett 3, das im Bereich der Schweißnaht 2 einen oberen Rand 5 und daran angrenzend einen seitlichen Rand 6 aufweist. Im Übergang der Ränder 5 und 6 befindet sich die Abrißkante 4, die zunächst von dem oberen Rand 5 etiketteinwärts abbiegt um dann in einer gegenläufigen Kurve auf den Rand 6 des Etiketts zuzulaufen, auf den sie im wesentlichen rechtwinklig auftrifft. Die S-förmige Abrißkante 4 hat einen im wesentlichen sinusförmigen Verlauf um die Achse 8, welche die Etikettränder 5 und 6 mit einem Winkel α von 135° schneidet und damit mit dem fortgefallenen Eckbereich des Etiketts ein gleichschenkliges Dreieck definiert.Figure 1 shows a preferred embodiment of an inventive Hose packaging with a label placed on it. The hose packaging 1 itself consists of a film tube attached to its two Ends is sealed via welds or adhesive seams 2. It goes without saying that under the term "weld seam" used here also other types Seals are to be understood, such as glued seams. On the hose packaging is the label 3 in the area of the weld 2 a has an upper edge 5 and adjacent thereto a lateral edge 6. in the Transition of the edges 5 and 6 is the tear-off edge 4, which is initially from the upper edge 5 turns inward in the label and then in an opposite direction Curve to run towards the edge 6 of the label on which it is essentially strikes at right angles. The S-shaped tear-off edge 4 has one sinusoidal course around the axis 8, which the label edges 5 and 6 with intersects an angle α of 135 ° and thus with the dropped Corner of the label defines an isosceles triangle.

Im Bereich der Schweißnaht 2 befinden sich Einkerbungen 7, die als Aufreißhilfe gedacht sind. Die Einkerbungen, die sich, bezogen auf die Längsrichtung der Schlauchverpackung, oberhalb der Abrißkante 4 befinden, führen beim Aufreißen zu einem Riß, der beim Durchlaufen der Folie auf die Abrißkante 4 trifft und von dieser in Richtung auf den Punkt D am seitlichen Rand 9 der Verpackung 1 geführt wird. Die mit der erfindungsgemäßen Schlauchverpackung erfindungsgemäß erzielte Öffnung verläuft also von dem Aufreißpunkt 7 oberhalb der Abrißkante 4 zu dieser hin und weiter zum Endpunkt D an der Verpackung 1 und von dort auf der Rückseite zum Aufreißpunkt 7 zurück, und ergibt somit eine wohl definierte Öffnung vorbestimmten Ausmaßes.In the area of the weld 2 there are notches 7, which as Tear aid are intended. The notches that are related to the Longitudinal direction of the hose packaging, located above the tear-off edge 4, lead to a tear when torn, which when passing through the film on the Tear edge 4 meets and from this towards point D on the side Edge 9 of the packaging 1 is guided.
