Description

Verfahren zur Herstellung von mit Kunststoffolien ausgekleideten Konservendosen Viele Füllgüter für Konservendosen, vorwiegend solche von saurer Beschaffenheit, greifen während der Sterilisation sowie bei der Lagerung das zur Dosenherstellung verwendete Eisen an. Bei der handelsüblichen Weißblechdose ist daher das Eisenblech durch einen Überzug aus Zinn geschützt.Process for the production of tin cans lined with plastic sheeting Many fillings for cans, mainly those of an acidic nature, use during the sterilization as well as during storage to manufacture the cans used iron. The iron sheet is therefore used in the commercially available tinplate can protected by a tin coating.

Zum gleichen Zweck werden die Innenseiten der Dosen häufig mit Lacken überzogen. Auch ist es bekannt, Konservendosen aus mit Kunststoffolien kaschiertem Schwarzhlech herzustellen.The insides of the cans are often coated with varnish for the same purpose overdrawn. It is also known to make tin cans laminated with plastic films To produce black lech.

Es wurde nun gefunden, daß man in technisch besonders vorteilhafter und einfacher Weise mit Kunststoffolien, vorzugsweise Folien aus Polyvinylchlorid, ausgekleidete Konservendosen herstellen kann, wenn man geschweißte oder gelötete Schwarzblechrümpfe einzeln mit den Folien auskleidet. Das Aufbringen der vorzugsweise mit einem Klebefilm versehenen Folie kann maschinell erfolgen. Die Haftung zwischen Folie und Blech wird durch Anwendung von Druck und Wärme herbeigeführt. Die Folie wird durch eine Abschneidevorrichtung in solchen Längen abgetrennt, daß sich die Folienenden überlappen, wodurch eine sichere Innenabdichtung entsteht; die Überlappung kann. entweder versetzt zu der Schweißnaht oder vorteilhaft wegen; der durch die doppelte Folienlage an der Überlappungsstelle erhöhten Schutz wirkung über der Schweißnaht angebracht werden. It has now been found that it is technically particularly advantageous and simply with plastic films, preferably films made of polyvinyl chloride, Lined tin cans can be made if one is welded or soldered Blackplate hulls individually lined with the foils. Applying the preferably Foil provided with an adhesive film can be done by machine. The liability between Foil and sheet metal is created by applying pressure and heat. The foil is cut by a cutting device in such lengths that the Overlap the ends of the film, creating a secure internal seal; the overlap can. either offset to the weld seam or advantageous because of; that by the double Foil layer at the point of overlap increases the protective effect over the weld seam be attached.

Nach dem Kaschieren des Rumpfes niff der Folie wird der Boden, der aus mit einer gleichartigen Kunststoffolie kaschiertem Blech hergestellt ist wie -ublich eingefalzt und die Dose ist füllfertig. After covering the hull with the foil, the floor becomes the is made of sheet metal laminated with a similar plastic film as - usually folded in and the can is ready to be filled.
