Description

"Aufreiß für Weißbleohdoesen, insbesondere für Fischdosen" Beschreibung Es ist bekannt, die Reißlinien, beispielsweise in den Deckeln von Fischdosen, unter möglichst geringer Beanspruchung der Zinnschioht des Weißblech zu erzeugen, um Korrosionmöglichkeiten auszuschließen. Dieses Verfahren hat den Nachteil daß das Aufreißen der Dosen nicht immer zufriedenstellend erfolgt, so daß Büchsenijffner zu Hilfe genommen werden müssen, durch deren Benutzung aber der Spiegel des Füllgutes in der Dose meist erheblich beschädigt wird."Tear open for white tin cans, especially for fish cans" Description It is known that the tear lines, for example in the lids of fish cans, under To generate as little stress as possible on the tinplate of the tinplate in order to avoid corrosion to exclude. This method has the disadvantage that the cans do not tear open always done satisfactorily, so that Büchsenijffner are used to help have to, but through their use the level of the product in the can is usually considerable damaged.

Diese Nachteile werden gemäß der Erfindung dadurch beseitigt, daß man mit der Einbringung der Reißlinie bis in die Eisenschioht des Weißbleches unter bewußter Schädigung der Oberflächenschutzschicht hineingeht und dann das Blech im Bereich der erzeugten Reißlinie durch eine Schutzschicht gegen jede mögliche Korrosion abdeckt. These disadvantages are eliminated according to the invention in that with the introduction of the tear line into the iron layer of the tinplate deliberate damage to the surface protective layer goes in and then the sheet metal in Area of the generated tear line through a protective layer against any possible corrosion covers.

In der Zeichnung ist als Beispiel ein Deckel a einer Fischdose dargestellt, der in seinem Rand die bekannte Abdichtung d enthält. Im Mittelteil der Unterseite dieses Deckels a ist eine durch eine gestrichelte Linie angedeutete Reißlinie b b so tief eingearbeitet, daß dadurch bewußt die Oberflächenschutzschicht des Blechs beschädigt wird. Um diese Beschädi- gung wirkungslos zu machen, ist sie durch einen lackauftrag c abgedeckt.In the drawing, a lid a of a fish box is shown as an example, which contains the known seal d in its edge. In the middle part of the underside of this lid a is a tear line indicated by a dashed line b b incorporated so deep that the surface protective layer of the sheet is deliberately damaged. To avoid this damage It can be made ineffective by applying a varnish c covered.
