Description

Die Erfindung betrifft ein streifenförmiges Verschlußelement, insbesondere zum Verschließen tütenförmiger Verpackungen, das um die Verpackung wickelbar und durch mindestens einen eingearbeiteten Draht gegen selbsttätiges öffnen gesichert ist.The invention relates to a strip-shaped closure element, in particular for closing bag-shaped packaging, which can be wound around the packaging and is secured against automatic opening by at least one incorporated wire.

Solche Verschlußelemente sind als Verschlußklips insbesondere aus dem Lebensmittelbereich vielfach bekannt. So werden beispielsweise Nudeln, Haferflocken, Gewürze, Tee und andere streufähige Lebensmittel häufig in mit solchen Elementen verschlossenen Tüten angeboten. Diese Verschlußelemente haben dabei den Vorteil, daß sie nach Anbruch der Verpackung zu ihrem Verschließen wiederverwendet werden können. Auch können solche Verschlußklips nach Ausbrauch der Packung aufbewahrt und im Haushalt zum Verschließen anderer, in Plastiktüten verpackter Lebensmittel verwendet werden. Nachteilig an den bekannten Verschlußelementen ist jedoch, daß bei Verpackungen mit solchen Verschlußelementen nicht ersichtlich ist, ob die Verpackung bereits schon einmal geöffnet worden ist. Gerade im Lebensmittelbereich ist eine solche Kontrollmöglichkeit jedoch wünschenswert und vielerorts auch schon Vorschrift, um Gesundheitsgefährdungen der Bevölkerung durch Einbringen von Fremdkörpern oder dergleichen in die Verpackungen ausschließen zu können.Such closure elements are widely known as closure clips, in particular from the food sector. For example, pasta, oatmeal, spices, tea and other scatterable foods are often offered in bags sealed with such elements. These closure elements have the advantage that they can be reused to close them after the packaging has been opened. Such closure clips can also be stored after the pack has been used up and used in the household to close other foods packaged in plastic bags. A disadvantage of the known closure elements, however, is that in the case of packaging with such closure elements it is not evident whether the packaging has already been opened. In the food sector in particular, however, such a control option is desirable and in many places it is already a requirement to be able to rule out health risks to the population by introducing foreign bodies or the like into the packaging.

Zur Lösung dieses Problems wird daher ein Verschlußelement der eingangs genannten Art vorgeschlagen, das erfindungsgemäß dadurch gekennzeichnet ist, daß das freie Ende des Verschlußelements durch Aufbringen eines thermoplastischen Materials an einem anderen Teil des Verschlußelements und/oder an der Verpackung befestigt ist, wobei das thermoplastische Material eine innige Verbindung mit dem Material des Verschlußelementes und/oder der Verpackung eingeht. Durch diese Fixierung des Endes des Verschlußelements mit Hilfe eines thermoplastischen Materials vereinigt das erfindungsgemäße Verschlußelement die Vorteile der seitherigen Verschlußelemente - nämlich Wiederverwendbarkeit zum Verschluß der gleichen oder anderer Verpackungen - mit einem versiegelbaren Verschluß, der anzeigt, ob die Verpackung schon einmal geöffnet worden ist. Durch die innige Materialverbindung zwischen thermoplastischem Material und Verschlußelement bzw. Verpackung ist gewährleistet, daß nach einem öffnen der Verpackung ein Teil des Materials des Verschlußelements am Siegelpunkt hängenbleibt. Dadurch ist auch bei einem Wiederverschließen der Verpackung ein einmal erfolgtes öffnen stets nachweisbar. Das thermoplastische Material kann zwischen das freie Ende des Verschlußelements und den darunterliegenden Teil des Verschlußelements und/oder der Verpackung aufgebracht sein und dadurch das freie Ende mit einem anderen Teil des Verschlußelements oder der Verpackung verkleben. Die Versiegelung des Verschlußelements ist damit von außen nicht sichtbar. Bei einer anderen Variante kann das thermoplastische Material auf der Außenseite des freien Endes des Verschlußelements aufgebracht sein und sich bis auf den an das freie Ende angrenzenden Bereich des unter dem freien Ende liegenden Teils des Verschlußelements und/oder der Verpackung erstrecken. Hier bildet das thermoplastische Material eine Art Verschlußlasche, die das freie Ende des Verschlußelements von außen mit einem anderen Teil des Verschlußelements oder der Verpackung verbindet. Das thermoplastische Material kann dabei ein heißschmelzender Kleber oder aber auch Siegellack sein. Als Echtheitsgarantie kann zudem in das thermoplastische Material ein Stempel- oder Siegelabdruck eingeprägt sein. Hierdurch ist zusätzlich sichergestellt, daß nicht ein unbefugtes öffnen der Verpackung durch erneutes Anschmelzen und Verschließen der Verpackung kaschiert werden kann. Für das Verschlußelement können hierbei verschiedene Materialien verwendet werden. Besonders kostengünstig und umweltfreundlich ist hierbei seine Herstellung aus Papier.To solve this problem, a closure element of the type mentioned is therefore proposed, which is characterized according to the invention in that the free end of the closure element is attached to another part of the closure element and / or to the packaging by applying a thermoplastic material, the thermoplastic material an intimate connection with the material of the closure element and / or the packaging. By fixing the end of the closure element with the aid of a thermoplastic material, the closure element according to the invention combines the advantages of the closure elements since then - namely reusability for sealing the same or different packaging - with a sealable closure which indicates whether the packaging has been opened before. The intimate material connection between the thermoplastic material and the closure element or packaging ensures that after opening the packaging part of the material of the closure element remains at the sealing point. As a result, once the packaging has been reclosed, it can always be verified that it has been opened. The thermoplastic material can be applied between the free end of the closure element and the underlying part of the closure element and / or the packaging and thereby glue the free end to another part of the closure element or the packaging. The sealing of the closure element is therefore not visible from the outside. In another variant, the thermoplastic material can be applied to the outside of the free end of the closure element and extend to the region of the part of the closure element and / or the packaging lying below the free end and adjoining the free end. Here, the thermoplastic material forms a type of sealing tab which connects the free end of the sealing element from the outside to another part of the sealing element or the packaging. The thermoplastic material can be a hot-melt adhesive or sealing wax. A guarantee of authenticity can also be found in the thermoplastic material a stamp or seal impression can be embossed. This additionally ensures that unauthorized opening of the packaging cannot be concealed by melting and closing the packaging again. Various materials can be used for the closure element. Its production from paper is particularly economical and environmentally friendly.

Nachfolgend werden bevorzugte Ausführungsbeispiele eines erfindungsgemäßen Verschlußelements anhand der Zeichnung näher erläutert.Preferred exemplary embodiments of a closure element according to the invention are explained in more detail below with reference to the drawing.

In detail show:
Fig. 1
a partial view of a package with a closure device according to the invention;
Fig. 2
a section through a second embodiment of a closure device;
Fig. 3
a section through a third embodiment of a closure device.

Fig. 1 zeigt eine tütenförmige Verpackung 10, um deren oberes zusammengefaßtes Ende 10.1 ein streifenförmiges Verschlußelement 11 gewickelt ist. Das Verschlußelement 11 ist aus Papier gefertigt und weist beidseitig eingearbeitete Drähte 12 und 13 auf, die dafür sorgen, daß das Verschlußelement 11 in seiner Lage bleibt und sich nicht selbsttätig öffnen kann. Das freie Ende 14 des Verschlußelements 11 ist mit Hilfe eines Tropfens 15 aus einem thermoplastischen Material mit der darunterliegenden Verpackung 10 verklebt. Eine öffnung der Verpackung 10 ist ohne Verletzung des als Siegel wirkenden Tropfens 15 aus thermoplastischem Material nicht möglich. Beim öffnen bleibt außerdem Material des Verschlußelementes am Tropfen hängen und zeigt ebenfalls ein erfolgtes öffnen an. Das dargestellte Verschlußelement 11 erlaubt somit eine wirksame Kontrolle, ob eine Verpackung vor Verkauf schon angebrochen worden ist.Fig. 1 shows a bag-shaped package 10, around the upper summarized end 10.1 a strip-shaped closure element 11 is wound. The closure element 11 is made of paper and has wires 12 and 13 incorporated on both sides, which ensure that the closure element 11 remains in its position and cannot open automatically. The free end 14 of the closure element 11 is glued to the underlying packaging 10 by means of a drop 15 made of a thermoplastic material. It is not possible to open the packaging 10 without damaging the drop 15 made of thermoplastic material which acts as a seal. When opening, material of the closure element also sticks to the drop and also indicates a successful opening. The illustrated closure element 11 thus allows an effective control as to whether a package has already been opened before it is sold.

Die Fig. 2 und 3 zeigen weitere Ausführungsbeispiele eines erfindungsgemäßen Verschlußelements, wobei hier das freie Ende des Verschlußelements nicht an der Verpackung, sondern an einem anderen Teil des Verschlußelements befestigt ist. So zeigt Fig. 2 ein in Schließstellung gebogenes Verschlußelement 20, dessen freies Ende 21 durch ein zwischen ihm und dem darunterliegenden Teil 22 des Verschlußelementes angeordneten Tropfen 23 aus einem thermoplastischen Material befestigt ist. Auch hier ist ein öffnen des Verschlußelements 20 ohne Zerstörung des Tropfens 23 nicht möglich. Im Gegensatz zum in Fig. 2 dargestellten Verschlußelement 20 ist beim Verschlußelement 30 aus Fig. 3 das freie Ende 31 mit dem darunterliegenden Teil 32 des Verschlußelements 30 durch einen Tropfen 33 aus thermoplastischem Material verbunden, der sich auf der Außenseite des freien Endes 31 bis über den angrenzenden Bereich des darunterliegenden Teils 32 des Verschlußelements 30 erstreckt und somit eine Art Verschlußlasche bildet, die beim öffnen des Verschlußelements 30 ebenfalls zerstört wird.2 and 3 show further exemplary embodiments of a closure element according to the invention, in which case the free end of the closure element is not fastened to the packaging but to another part of the closure element. 2 shows a closure element 20 bent in the closed position, the free end 21 of which is fastened by a drop 23 made of a thermoplastic material arranged between it and the part 22 of the closure element located underneath it. Here, too, it is not possible to open the closure element 20 without destroying the drop 23. In contrast to the closure element 20 shown in FIG. 2, in the closure element 30 from FIG. 3 the free end 31 is connected to the underlying part 32 of the closure element 30 by a drop 33 made of thermoplastic material which extends on the outside of the free end 31 to extends the adjacent area of the underlying part 32 of the closure element 30 and thus forms a type of closure flap which is also destroyed when the closure element 30 is opened.
