Firma J. A.Schmalbach Blechwarenwerke A.-G., Braunachwei, Hamburger Str. 37/41 "Aufreiß für Blechdosen, insbesondere für Fisohdosen" Beschreibung Um bei Sohwarzblechdosen, die beispielsweise nur mit einer aus eingebranntem Lack bestehenden Oberflächenschutzschicht versehen sind, einen ausschußlosen und stets genau der Reißlinie folgenden Aufreiß zu erhalten, ist es gemäß der Erfindung erforderlich, die Reißlinie so tief in daß Schwarzblech einzubringen, daß die Oberflächenschutzschicht gegebenenfalls auf beiden Seiten des Blechs beschädigt wird.J. A. Schmalbach Blechwarenwerke A.-G., Braunachwei, Hamburger Str. 37/41 "Tear open for tin cans, especially for fisoh cans" Description Um in the case of black tin cans that, for example, only have one made of baked-in paint Surface protection layer are provided, a scrapless and always exactly that To obtain tear line following tear, it is necessary according to the invention, to bring the tear line so deep into the black plate that the surface protective layer possibly damaged on both sides of the sheet metal.

Dieser Nachteil wird nach der Erzeugung der Reißlinie durch Auftragen einer Abdeckschicht z.B. aus Lack, beseitigt.This disadvantage becomes apparent after the tear line has been created by application a covering layer, e.g. made of paint.

Bei Aluminiumbleohdosen ist es zur Erzeugung eines aussohußlosen, stets genau der Reißlinie folgenden Aufreiß ebenfalls erforderlich, die Reißlinie in das Blech, das meist eloxiert und gegebenenfalls auch noch lackiert ist, so tief einzuarbeiten, daß die Oberflächenschicht beschädigt und das dem Füllgut nachteilige Aluminium freigelegt wird. Auch dieser Nachteil wird nach der Erzeugung der Reißlinie durch das Auftragen einer Abdeokaohioht, s. B. aus - 0 u. hr........... In the case of leaded aluminum cans, in order to create a tear-free tear that always follows the tear line exactly, it is also necessary to work the tear line so deeply into the sheet metal, which is usually anodized and possibly also painted, that the surface layer is damaged and the aluminum, which is detrimental to the contents, is exposed . This disadvantage also becomes apparent after the tear line has been created by applying an abdeokaohioht, see for example - 0 a.m. ...........

Lack, beseitigt.Paint, eliminated.

In der Zeichnung ist als Beispiel ein Deckel a einer Fischdose dargestellt, die aus Schwarzblech bezw. aus Aluminiumblech besteht und die im Rande eine bekannte Abdichtung d enthält. Im Mittelteil der Unterseite und/oder der Oberseite dieses Deckels a ist eine durch eine gestrichelte Linie angedeutete Reißlinie b so tief eingearbeitet, daß dadurch die Oberflächenschutzschicht, die beispielsweise bei Schwarzblechdosen aus eingebranntem Lack und bei Aluminiumbleohdosen aus einer lackierten Eloxierschicht besteht, beschädigt wird, so daß das Schwarzblech bezw. das Aluminiumblech freigelegt ist. Da das freigelegte Metall für die Aufbewahrung von Nahrungs- und Genußmitteln nachteilig ist, ist das freiliegende Metall, gegebenenfalls auf beiden Seiten des Deckels, durch eine Schutzschicht c z. B. aus Lack abzudecken. In the drawing, a lid a of a fish tin is shown as an example, those made of black plate respectively. consists of aluminum sheet and the edge is a well-known one Seal d contains. In the middle part of the bottom and / or the top of this Lid a is a tear line indicated by a dashed line b so deep incorporated that thereby the surface protective layer, for example at Black tin cans made from baked-in lacquer and, in the case of bleoh aluminum cans, from a lacquered one There is anodizing layer, is damaged, so that the black plate BEZW. the aluminum sheet is exposed. Since the exposed metal is used for food and A disadvantage is the exposed metal, possibly on both Sides of the lid, through a protective layer c z. B. to cover from paint.
