Description

Die Erfindung betrifft eine Vorrichtung zum reversiblen Verschließen von Kunststoffbeuteln mit einem am zu öffnenden Beutelende festlegbaren Klemmelement.The invention relates to a device for reversibly closing Plastic bags with one that can be attached to the opening of the bag Clamping element.

Bei in Kunststoffbeuteln angebotenen Produkten tritt in der Praxis häufig die Schwierigkeit auf daß der Kunststoffbeutel nach dem erstmaligen Öffnen - wenn überhaupt - nur mühsam wieder so verschlossen werden kann, daß ein bestmöglicher Produktschutz trotz vorheriger Öffnung gewährleistet wird. Aus der Praxis sind zum Verschließen von Kunststoffbeuteln verschiedene Klammersysteme nach dem Prinzip der Büroklammer bekannt, mit denen der geöffnete Beutel wieder zu verschließen sein soll. Darüber hinaus sind Federklammern sowie Klammern mit Rastnocken bekannt. All diese bekannten Verschlußsysteme für Kunststoffbeutel haben den Nachteil, daß sie den Kunststoffbeutel nicht ausreichend verschließen und/oder für den Verbraucher sehr umständlich zu handhaben sind, da sie nicht am Beutel verbleiben und/oder in der Massenfertigung nicht umweltgerecht herstellbar sind.In the case of products offered in plastic bags, this often occurs in practice Difficulty that the plastic bag after opening for the first time - if at all - can only be closed with difficulty that a best possible product protection is guaranteed despite previous opening. From the There are various practices for closing plastic bags Clamp systems known according to the principle of the paper clip, with which the open bags should be closed again. Beyond that Spring clips and clips with locking cams are known. All of these familiar Closure systems for plastic bags have the disadvantage that they Do not seal the plastic bag sufficiently and / or for the consumer are very cumbersome to handle, since they do not remain on the bag and / or cannot be produced in an environmentally friendly manner in mass production.

Davon ausgehend liegt der Erfindung das technische Problem zugrunde, eine Vorrichtung zum reversiblen Verschließen von Kunststoffbeuteln bereitzustellen, die ein produktschonendes Verschließen eines einmal geöffneten Kunststoffbeutels erlaubt und darüber hinaus für den Benutzer einfach und sicher handhabbar ist.Proceeding from this, the invention is based on the technical problem of providing a device for reversibly closing plastic bags, which allows a plastic bag to be closed gently once it is opened and, moreover, is easy and safe for the user to handle.

Die technische Lösung dieser Aufgabenstellung ist dadurch gekennzeichnet, daß das Klemmelement zwei im wesentlichen rechteckige, gegeneinander klappbare Schenkel aufweist, die über ein Scharnier miteinander verbunden sind, und daß an einem Ende der Schenkel ein Befestigungselement angeordnet ist, über das einerseits die beiden Schenkel im gegeneinander geklappten Zustand fixierbar und andererseits das Klemmelement am Kunststoffbeutel festlegbar ist und das als Drehachse zum Verschränken des Klemmelements dient.The technical solution to this problem is characterized in that the clamping element has two substantially rectangular, mutually foldable legs, which are connected to one another via a hinge, and that a fastening element is arranged at one end of the legs, via which on the one hand the two legs in the other folded state fixable and on the other hand the clamping element can be fixed to the plastic bag and serves as an axis of rotation for interlocking the clamping element.

Die erfindungsgemäße Ausgestaltung des Verschlusses hat den Vorteil, daß dieser über das Befestigungselement fest an dem zu verschließenden Beutel festlegbar ist, so daß der Verschluß immer am Beutel verbleibt und eine einfache Handhabung auch bei wiederholter Einsetzbarkeit des Verschlusses gewährleistet. Gemäß einer bevorzugten Ausführungsform der Erfindung ist das Befestigungselement als auf einer Innenseite eines Schenkels angeordneter Dorn zum Durchstoßen der Folie des Kunststoffbeutels ausgebildet, der in einer in dem anderen Schenkel ausgebildeten Öffnung festlegbar ist. Durch die Ausbildung des Befestigungselementes als Dorn ist es besonders einfach, das Klemmelement dadurch am Kunststoffbeutel zu befestigen, daß der die beiden Schenkel des Klemmelements miteinander verbindende Dorn die Kunststoffolie durchstößt.The design of the closure according to the invention has the advantage that this via the fastener firmly on the bag to be closed can be fixed so that the closure always remains on the bag and a simple one Handling even with repeated use of the closure guaranteed. According to a preferred embodiment of the invention, this is Fastening element as arranged on an inside of a leg Mandrel for piercing the film of the plastic bag formed in a in the other leg formed opening can be fixed. Through the Training the fastener as a mandrel, it is particularly easy that To fix the clamping element on the plastic bag that the two Leg of the clamping element interconnecting mandrel the plastic film pierces.

Gemäß einer praktischen Ausführungsform der Erfindung wird vorgeschlagen, daß am freien Ende des Dorns ein eine Hinterschneidung bildender, den Schaft des Dorns überragender Kopf ausgebildet ist. Diese Hinterschneidung gewährleistet dadurch einen sicheren Halt der beiden gegeneinander geklappten Schenkel aneinander, indem der über die Öffnung auf den Kopf des Dorns aufgedrückte Schenkel den Kopf des Dorns hintergreift. Um das Aufschieben des Klemmelements auf das zu verschließende Beutelende zu erleichtern, sind gemäß einer bevorzugten Ausführungsform der Erfindung die freien Längskanten der beiden Schenkel des Klemmelements derart nach außen gerichtet, daß sie eine Einschuböffnung bilden.According to a practical embodiment of the invention, it is proposed that that at the free end of the mandrel an undercut forming the shaft the mandrel protruding head is formed. This undercut thereby ensures a secure hold of the two folded against each other Thighs together by placing the opening on the head of the mandrel pressed leg reaches behind the head of the thorn. To postpone the Clamping element on the bag end to be closed are easier according to a preferred embodiment of the invention, the free longitudinal edges the two legs of the clamping element so directed outwards that they form an insertion opening.

Weiterhin wird mit der Erfindung vorgeschlagen, daß das Scharnier, über das die beiden Schenkel des Klemmelements miteinander verbunden sind, als Filmscharnier ausgebildet ist. Durch die Ausbildung als Filmscharnier ist es möglich, das gesamte Klemmelement einstückig, beispielsweise als Spritzgußteil herzustellen. Schließlich wird mit der Erfindung vorgeschlagen, daß auf beiden Innenseiten der Schenkel versetzt zueinander Klemmrippen ausgebildet sind. Durch diese Klemmrippen wird im auf die Öffnung aufgesetzten Zustand des Klemmelements die verschließende Klemmkraft der beiden über den Dorn miteinander verbundenen Schenkel verstärkt, so daß ein optimaler Produktschutz gewährleistet ist.Furthermore, it is proposed with the invention that the hinge over which the two legs of the clamping element are connected together as Film hinge is formed. By training as a film hinge it is possible, the entire clamping element in one piece, for example as an injection molded part to manufacture. Finally, the invention proposes that on both Inside of the legs are offset from each other clamping ribs are formed. By means of these clamping ribs, the Clamping element the closing clamping force of the two over the mandrel interconnected legs reinforced so that an optimal Product protection is guaranteed.

Weitere Vorteile und Merkmale der Erfindung ergeben sich aus der nachfolgenden Beschreibung der zugehörigen Zeichnung, in der ein Ausführungsbeispiel einer erfindungsgemäßen Vorrichtung zum reversiblen Verschließen von Kunststoffbeuteln dargestellt ist. In der Zeichnung zeigt:

  • Fig. 1 eine perspektivische Ansicht eines Kunststoffgebindes mit einem daran festzulegenden Verschluß;
  • Fig. 2 eine schematische Seitenansicht eines noch geschlossenen Kunststoffbeutels ohne Verschluß und
  • Fig. 3 eine schematische Seitenansicht gemäß Fig. 2, jedoch mit am Kunststoffbeutel festgelegtem Verschluß.
    • Further advantages and features of the invention result from the following description of the associated drawing, in which an embodiment of a device according to the invention for the reversible closure of plastic bags is shown. The drawing shows:
  • Figure 1 is a perspective view of a plastic container with a closure to be fixed thereon.
  • Fig. 2 is a schematic side view of a still closed plastic bag without a closure and
  • Fig. 3 is a schematic side view of FIG. 2, but with the closure attached to the plastic bag.

    • Fig. 1 zeigt in einer perspektivischen Ansicht einen Kunststoffbeutel 1, an dessen zu öffnendem Beutelende ein Klemmelement 2 zum reversiblen Verschließen des Kunststoffbeutels 1 festlegbar ist. Wie aus Fig. 1 ersichtlich, besteht das Klemmteil 2 aus zwei Schenkeln 3, die über ein Filmscharnier 4 miteinander verbunden sind. Das Festlegen des Klemmelementes 2 an dem Kunststoffbeutel 1 erfolgt bei dem dargestellten Ausführungsbeispiel über einen Dorn 5, der durch die Kunststoffolie des Kunststoffbeutels 1 hindurchdrückbar ist. Neben dem Festlegen des Festklemmelements 2 am Kunststoffbeutel 1 dient der Dorn 5 dazu, die beiden Schenkel 3 des Klemmelements 2 im gegeneinander zusammengeklappten Zustand aneinander zu fixieren. Fig. 1 shows a perspective view of a plastic bag 1, on the to open the end of the bag, a clamping element 2 for reversible closing of the plastic bag 1 can be fixed. As can be seen from Fig. 1, there is Clamping part 2 from two legs 3, which are connected to one another via a film hinge 4 are connected. Fixing the clamping element 2 on the plastic bag 1 takes place in the illustrated embodiment via a mandrel 5 through the plastic film of the plastic bag 1 can be pushed through. Next to the Fixing the clamping element 2 on the plastic bag 1 serves the mandrel 5 to do this, the two legs 3 of the clamping element 2 against each other collapsed state to fix together.

    Mit einem solchermaßen ausgestalteten Verschluß läßt sich ein Kunststoffbeutel 1 wie folgt reversibel verschließen: Zunächst wird der Kunststoffbeutel 1 entlang einer Schnittlinie 6 aufgeschnitten, so daß das in dem Kunststoffbeutel 1 beinhaltete Produkt entnommen werden kann. Nach dem Öffnen des Kunststoffbeutels 1 wird das Klemmelement 2 mit Hilfe des Dorns 5 an dem Kunststoffbeutel 1 befestigt. Hierzu wird der Dorn 5 an einem am geöffneten Ende des Kunststoffbeutels 1 markierten Befestigungspunkt 7 durch die Kunststoffolie des Kunststoffbeutels hindurchgedrückt. Anschließend werden die beiden Schenkel 3 des Klemmelements 2 - wie durch den Pfeil 8 in Fig. 1 angedeutet - über das Filmscharnier 4 gegeneinander geklappt, bis eine Öffnung 9 in dem einen Schenkel 3 mit dem Dorn 5 des anderen Schenkels 3 in Eingriff tritt. Zum Fixieren des Dorns 5 in der Öffnung 9 ist an dem freien Ende des Dorns 5 ein eine Hinterschneidung bildender Kopf 10 ausgebildet, der die Ränder der Öffnung 9 übergreift und so die Schenkel 3 des Klemmelements 2 fest miteinander verbindet.With such a closure, a plastic bag can be 1 reversibly close as follows: First, the plastic bag 1 is along a cut line 6 cut open, so that in the plastic bag 1 included product can be removed. After opening the Plastic bag 1, the clamping element 2 using the mandrel 5 on the Plastic bag 1 attached. For this purpose, the mandrel 5 is opened on one End of the plastic bag 1 marked attachment point 7 by the Plastic film of the plastic bag pushed through. Then the two legs 3 of the clamping element 2 - as indicated by the arrow 8 in Fig. 1st indicated - folded over the film hinge 4 against each other until an opening 9 in one leg 3 with the mandrel 5 of the other leg 3 in engagement occurs. To fix the mandrel 5 in the opening 9 is at the free end of the mandrel 5 an undercut head 10 is formed, which the edges of the Opening 9 engages and so the legs 3 of the clamping element 2 firmly connects with each other.

    Der Dorn 5 zum Festlegen des Klemmelements 2 am Kunststoffbeutel 1 sowie zum Verbinden der beiden Schenkel 3 des Klemmelements 2 dient gleichzeitig auch als Drehachse, um die das gesamte Klemmelement 2 zum Öffnen und Verschließen des Kunststoffbeutels 1 verschwenkbar ist, wie dies durch den Pfeil 11 in Fig. 3 angedeutet ist. Die Klemmkraft des Klemmelements 2 auf dem Kunststoffbeutel 1 kann beispielsweise dadurch verstärkt werden, daß auf den einander zugewandten Innenseiten der Schenkel 3 Klemmrippen 12 ausgebildet sind, wie dies in Fig. 1 zu erkennen ist. Die Klemmkraft des Klemmelements 2 sowie die Dichtigkeit des solchermaßen ausgebildeten Verschlusses wird dabei dadurch erhöht, daß die Klemmrippen 12 versetzt zueinander angeordnet sind. Um ein einfaches Aufschieben des Klemmelements 2 auf das zu verschließende freie Ende des Kunststoffbeutels 1 zu ermöglichen, sind die freien Längskanten 13 der Schenkel 3 des Klemmelements 2 nach außen ausgestellt ausgebildet, so daß sich zwischen den gegeneinander geklappten Schenkeln 3 eine Einschuböffnung bildet, die als Führung für das zwischen den Schenkeln 3 aufzunehmende Kunststoffmaterial des Kunststoffbeutels 1 dient.The mandrel 5 for fixing the clamping element 2 on the plastic bag 1 and serves to connect the two legs 3 of the clamping element 2 simultaneously also as an axis of rotation around which the entire clamping element 2 can be opened and Closing the plastic bag 1 is pivotable, as indicated by the arrow 11 is indicated in Fig. 3. The clamping force of the clamping element 2 on the Plastic bag 1 can be reinforced, for example, that the mutually facing inner sides of the legs 3 clamping ribs 12 formed are, as can be seen in Fig. 1. The clamping force of the clamping element 2 as well as the tightness of the closure formed in this way increased in that the clamping ribs 12 are arranged offset from one another. In order to simply slide the clamping element 2 onto the one to be closed To allow the free end of the plastic bag 1 are the free longitudinal edges 13 the leg 3 of the clamping element 2 is designed to be exposed to the outside, so that between the folded legs 3 a Forms the insertion opening, which acts as a guide for the between the legs 3 plastic material of the plastic bag 1 to be used.

    Ein solchermaßen ausgebildeter reversibler Verschluß für einen Kunststoffbeutel zeichnet sich dadurch aus, daß dieser wiederholt einsetzbar und leicht handhabbar ist, da er so lange am Kunststoffbeutel 1 verbleibt, wie die beiden Schenkel 3 des Klemmelements 2 über den Dorn 5 miteinander verbunden sind. Durch den Verbleib des Verschlusses am Kunststoffbeutel 1 wird darüberhinaus eine einhändige Bedienung des Verschlusses ermöglicht, wodurch die Handhabbarkeit weiter verbessert wird. Als weiterer Vorteil eines solchermaßen ausgestalteten Verschlusses ist anzumerken, daß dieser nach dem Lösen der Verbindung der beiden Schenkel 3 miteinander sowie der Verbindung des Klemmelements 2 mit dem Kunststoffbeutel 1 über den Dorn 5 der Verschluß zum Verschließen weiterer Kunststoffbeutel 1 verwendet werden kann. Such a reversible closure designed for a plastic bag is characterized by the fact that it can be used repeatedly and easily is manageable, since it remains on the plastic bag 1 as long as the two Leg 3 of the clamping element 2 are interconnected via the mandrel 5. By remaining the seal on the plastic bag 1 is also allows one-handed operation of the closure, which makes the Manageability is further improved. Another advantage of such a way designed closure should be noted that this after loosening the Connection of the two legs 3 together and the connection of the Clamping element 2 with the plastic bag 1 over the mandrel 5 the closure for closing additional plastic bag 1 can be used.
