Abstract

A package (1, 11) for sheathed welding electrodes (2, 12) or similar hygroscopic objects, in which a small number of welding electrodes, lying adjacently in parallel, are sealed in between two laminated films (15) excluding air to a great extent, the two laminated films having an increased sealing capacity in relation to oxygen and water vapour. <IMAGE>

Description

Die Erfindung bezieht sich auf eine Verpackung für ummantelte Schweißelektroden od.dgl. hygroskopische Gegenstände sowie auf eine Verbundfolie zum Herstellen einer solchen Verpackung.The invention relates to a packaging for covered welding electrodes or the like hygroscopic Objects as well as on a composite film for producing a such packaging.

Bei den meisten ummantelten Schweißelektroden besteht das Problem, daß die Ummantelung sehr empfindlich auf Feuchtigkeit ist. Bereits kurzzeitiges Liegen an der Luft ist durch die damit verbundene Feuchtigkeitsaufnahme so schädlich, daß die Elektroden qualitativ stark abbauen und sich das Schweißergebnis verschlechtert. Um sie wieder einsetzen zu können, müssen sie in einer speziellen Einrichtung rückgetrocknet werden.This is the case with most coated welding electrodes Problem that the sheath is very sensitive to Moisture is. Lying in the air for a short time is so through the associated moisture absorption harmful that the electrodes degrade in quality and the welding result deteriorates. To them again To be able to use them, they must be in a special Device can be dried again.

Um die Schweißelektroden wenigstens während des Versendens nicht zu beeinträchtigen, werden besonders empfindliche Elektroden bereits in luftdichte Blechgebinde verpackt. Solche Blechgebinde sind jedoch wirtschaftlich nur vertretbar, wenn eine verhältnismäßig große Stückzahl in einem Gebinde verpackt wird. Gerade dabei ist es aber nachteilig, daß nach dem Öffnen der Packung sehr viele Elektroden offen sind, die nicht innerhalb kurzer Zeit verarbeitet werden können.Around the welding electrodes at least during shipping not to be affected, become particularly sensitive Electrodes already packed in airtight metal containers. Such sheet metal containers are only economical justifiable if a relatively large number in is packed in a container. But that's exactly what it is disadvantageous that very many after opening the package Electrodes are open that are not in a short time can be processed.

Der Erfindung liegt daher die Aufgabe zugrunde, eine wirtschaftliche Verpackung für ummantelte Schweißelektroden zu schaffen, mit der auch eine geringe Anzahl von ummantelten Schweißelektroden sicher und haltbar verpackt, versendet und direkt aus der Verpackung verarbeitet werden kann.The invention is therefore based on the object economical packaging for coated welding electrodes to create with the also a small number of jacketed Welding electrodes securely packaged, shipped and can be processed directly from the packaging.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß eine geringe Anzahl von Schweißelektroden od.dgl. parallel nebeneinanderliegend zwischen zwei Verbundfolien unter weitgehendem Luftausschluß eingesiegelt ist, wobei die beiden Verbundfolien eine erhöhte Dichtigkeit gegenüber Sauerstoff und Wasserdampf aufweisen.This object is achieved in that a small number of welding electrodes or the like. parallel side by side between two composite films under extensive air exclusion is sealed, the compared to both composite foils an increased tightness Have oxygen and water vapor.

Bei höchsten Ansprüchen ist es möglich, die Schweißelektroden sogar einzeln zu verpacken. In den meisten Fällen wird es jedoch ausreichen, zwischen fünf und zehn Elektroden in eine gemeinsame Verpackung einzusiegeln.With the highest demands it is possible to use the welding electrodes even packaged individually. In most cases it will however, sufficient between five and ten electrodes in one seal common packaging.

Eine vorteilhafte Verbundfolie zum Herstellen einer solchen Verpackung ist erfindungsgemäß dadurch gekennzeichnet, daß auf eine Aluminiumfolie beiderseits ein Kaschierkleber aufgetragen ist, der wiederum eine OPA-Folie trägt.An advantageous composite film for the production of such Packaging is characterized according to the invention in that a laminating adhesive on both sides of an aluminum foil is applied, which in turn carries an OPA film.

Durch diese beiderseitige OPA-Folie mit der dazwischen eingebetteten Aluminiumfolie wird neben einer sehr guten Dichtigkeit auch eine hervorragende Durchstoßfestigkeit der Verpackung erzielt.Through this double-sided OPA film with the one in between embedded aluminum foil is next to a very good one Tightness also provides excellent puncture resistance Packaging achieved.

Sehr vorteilhaft ist es auch, wenn erfindungsgemäß auf der die Innenseite der Verpackung bildenden Seite der Verbundfolie über einen weiteren Kaschierkleber eine PE-Folie aufgebracht ist.It is also very advantageous if, according to the invention, on the the inside of the packaging forming side of the Composite film over another laminating adhesive PE film is applied.

Diese Polyäthylenfolie verbessert vor allem die Siegeleigenschaften und die Durchstoßfestigkeit der Verbundfolie ganz wesentlich; sie ist jedoch auch für deren übrige Eigenschaften vorteilhaft. This polyethylene film mainly improves the Sealing properties and the puncture resistance of the Composite film very essential; however, it is also for them other properties advantageous.  

Bei einer vorteilhaften Verbundfolie sind die beiden OPA-Folien etwa 15 Mikrometer stark, während die Aluminiumfolie eine Stärke von etwa 45 Mikrometer aufweist und die PE-Folie in einer Dicke von ca. 75 bis 100 Mikrometer vorgesehen ist, wobei der Kaschierkleber in einer Menge von 3 bis 5 g/m2 aufgetragen ist.In the case of an advantageous composite film, the two OPA films are approximately 15 micrometers thick, while the aluminum film has a thickness of approximately 45 micrometers and the PE film is provided in a thickness of approximately 75 to 100 micrometers, the laminating adhesive in an amount of 3 to 5 g / m 2 is applied.

Gerade mit diesem Aufbau haben sich sowohl bezüglich der Dichtigkeit als auch der mechanischen Festigkeit optimale Werte ergeben. Des weiteren ist die Verbundfolie in der Lage, ca. 20% gedehnt zu werden. Dies bedeutet, daß eine Schale tiefgezogen und das entsprechende Füllgut ohne Schwierigkeit eingelegt werden kann.Especially with this structure, both in terms of Tightness as well as the mechanical strength optimal Result in values. Furthermore, the composite film is in the Able to stretch about 20%. This means that a Deep-drawn shell and the corresponding filling material without Difficulty can be put.

In der Zeichnung ist die Erfindung anhand zweier Ausführungsbeispiele veranschaulicht. Dabei zeigen:In the drawing, the invention is based on two Exemplary embodiments illustrated. Show:
