Abstract

Obturator for a pouch made of a flexible material, in particular for domestic pouches made from plastic for the storage of frozen products, made from a cylindrical rod or cylindrical tube (1) as an inner profile member together with a similarly elongate three-quarter tubular member (2) made from an elastically rigid material, preferably plastic, as an outer profile member, having an internal diameter (y) corresponding to the external diameter (x) of the cylindrical rod or cylindrical tube (1). The internal diameter (y) of the outer profile member (2) slightly exceeds the external diameter (x) of the inner profile member (1), the inner profile member (1) and/or the outer profile member (2) being provided on the mutually facing surfaces with a clamping web (3) or with a plurality of such clamping webs. The outer profile member (2) is provided on its outer surface with a gripping strip (4) or with a plurality of such gripping strips, the inner profile member (1) having a greater length than the outer three-quarter tubular member (2).

Description

Die Erfindung betrifft einen Verschluß für Beutel aus einem flexiblen Material, insbesondere für Haushaltsbeutel aus Kunststoff zur Aufbewahrung von Gefriergut.The invention relates to a closure for bags made of a flexible material, in particular for household plastic bags for storing frozen goods.

Im Haushalt treten eine Vielzahl von Anwendungszwecken auf, in denen Beutel aus einem flexiblen Material vorübergehend flüssigkeitsdicht und gegebenenfalls soweit wie möglich auch luftdicht verschlossen werden müs­sen. Aufgrund der heute weit verbreiteten Tiekühltechnik ergeben sich eine Unzahl derartiger Bedarfsfälle, sie beschränken sich jedoch keines­wegs auf diesen Bereich. Die bisherigen Hilfsmittel für diesen Zweck kön­nen jedoch nur bedingt befriedigen.In the household there are a multitude of applications in which bags made of a flexible material have to be temporarily sealed liquid-tight and, if possible, also air-tight. Due to the widespread use of freezing technology today, there are a myriad of such needs, but they are by no means limited to this area. However, the previous tools for this purpose can only satisfy to a limited extent.

Die sicherste und derzeit - soweit erkennbar - am weitesten verbrei­tete Methode de Verschlusses von Kunststoffbeuteln ist das Verschweißen, das jedoch einerseits eine besondere Schweißeinrichtung erforder und einen im Ganzen doch beachtlichen Zeitaufwand erfordert und andererseits nur auf Beutel aus einem schweißbaren Material beschränkt bleiben muß. Der weiterhin verbreitete Verschluß mittels Gummiring oder ummanteltem Gummi­draht erfreut sich demgegenüber keiner großenn Beliebtheit, weil sie einerseits zu einem ungleichmäßigen und daher - etwa in der Tiefkühltruhe - schwer stapelbaren Gebinde führen. Darüberhinaus handelt es sich hierbei um sogenannte verlorene Verschlüsse, die in der Regel bereits nach einma­ ligem Gebrauch soweit beschädigt oder zerstört sind, so daß sie unmittel­bar verworfen werden.The safest and currently - as far as can be seen - the most widespread method of closing plastic bags is welding, which, however, on the one hand requires a special welding device and on the whole requires a considerable amount of time and on the other hand only has to be limited to bags made of a weldable material. The widespread closure by means of a rubber ring or sheathed rubber wire, on the other hand, is not very popular because on the one hand they lead to an uneven and therefore - for example in the freezer - difficult to stack containers. In addition, these are so-called lost closures, which usually already after one current use are damaged or destroyed so that they are immediately discarded.

Der vorliegenden Erfindung liegt als Aufgabe die Schaffung eines Ver­schlusses für Beutel aus flexiblem Material zugrunde, der einfacher Hand­habbarkeit und Gewährleistung eines sicheren Verschlusses beliebig wieder­verwendbar ist. Diese Aufgabe wird mit einem Verschluß mit den im Patent­anspruch 1 wiedergegebenen Merkmalen gelöst.The present invention has for its object to provide a closure for bags made of flexible material that is easy to use and ensure a secure closure reusable. This object is achieved with a closure having the features set out in claim 1.

Weitere Ausführungsformen und Vorteile ergeben sich aus der nachfol­genden Beschreibung, in der die Erfindung anhand der einen Verschluß in offener Stellung wiedergebenden Zeichnung beispielsweise erläutert ist.Further embodiments and advantages emerge from the following description, in which the invention is explained, for example, with reference to the drawing which shows a closure in the open position.

Der in der Zeichnung wiedergegebene Verschluß besteht aus einem Rohr­profil 1 beliebiger Länge als Innenprofilkörper, an dessen Stelle auch ein Vollprofil vorgesehen sein kann, sowie einem ebenfalls langgestreckten Dreiviertel-Rohrkörper 2 aus einem elastisch-steifen Material, vorzugs­weise Kunststoff, als Außenprofilkörper, der einen derart auf den Außen­durchmesser (x) des Rohrprofils 1 abgestimmten Innendurchmesser (y) auf­weist, daß sich die Teile - leer - in loser Anlage aneinander ineinander geclipst werden können. Im dargestellten Beispiel ist die Anordnung so ge­troffen, daß Innendurchmesser (y) des Dreiviertel-Rohrkörpers 2 den Außen­durchmesser (x) des Rundstabes bezw. Rundrohres 1 geringfügig übersteigt und der Rundstab bezw. das Rundrohr 1 und der Dreiviertel-Rohrkörper 2 auf den gegeneinander weisenden Flächen mit in der beschriebenen Weise abge­stimmten Klemmstegen 3 versehen sind. Der Dreiviertel-Rohrkörper 2 ist auf seiner Außenfläche mit einer Griffleiste 4 oder mehreren solcher Grifflei­sten versehen.The closure shown in the drawing consists of a tubular profile 1 of any length as an inner profile body, in its place a full profile can also be provided, and an also elongated three-quarter tubular body 2 made of an elastically rigid material, preferably plastic, as an outer profile body, which one such has the inner diameter (y) matched to the outer diameter (x) of the tubular profile 1, so that the parts - empty - can be clipped together in a loose system. In the example shown, the arrangement is such that the inner diameter (y) of the three-quarter tubular body 2 or the outer diameter (x) of the round rod. Round tube 1 slightly exceeds and the round rod. the round tube 1 and the three-quarter tubular body 2 are provided on the mutually facing surfaces with clamping webs 3 coordinated in the manner described. The three-quarter tubular body 2 is on provide its outer surface with a handle bar 4 or more such handle bars.

Zum Verschluß eines Beutels wird der obere Beutelrand fest um das Innenrohrprofil 1 geschlungen und anschließend der Dreiviertel-Rohrkörper 2 über das Innenrohrprofil geclipst, wobei aufgrund der abgestimmten Dimensionierung durch die Stärke des eingeclipsten Beutels eine feste Klemmspannung erzeugt wird. Hierbei wird aufgrund des durch die Klemmstege erzeugten linenförmigen Klemmdruckes ein absolut flüssigkeitsdichter Ver­schluß erzielt, wobei durch Aufclipten des Dreivietelrohres auf das Innen­profilrohr in der Weise, daß die Klemmstege möglichst nicht nebeneinander liegen, die Dichtwirkung noch bis auf eine dem Verschweißen nahekommende Dicht erhöht werden kann. Das Lösen erfolgt entsprechend umgekehrt durch Ausclipsen des Innenprofilrohres aus dem Dreiviertelrohr unter Nutzung der Griffleisten 4. Eine Beschädigung oder gar Zerstörung der Verschlußteile tritt hierbei nicht ein, so daß sie praktisch unbegrenzt wiederverwendbar sind.To close a bag, the upper edge of the bag is wrapped tightly around the inner tube profile 1 and then the three-quarter tube body 2 is clipped over the inner tube profile, a fixed clamping tension being generated due to the coordinated dimensioning by the thickness of the clipped-in bag. In this case, an absolutely liquid-tight seal is achieved due to the linen-like clamping pressure generated by the clamping webs, and by clipping the three-quarter pipe onto the inner profile tube in such a way that the clamping webs are not next to one another as far as possible, the sealing effect can be increased to a seal that is close to welding. The loosening is reversed accordingly by clipping the inner profile tube out of the three-quarter tube using the handle strips 4. Damage or even destruction of the closure parts does not occur, so that they can be reused practically indefinitely.
