Description
Die Erfindung betrifft einen Konservendosenverschluß mit einem Schraubring, der den Dosendeckel gegen einen Dichtungsring preßt und sich dabei an einem Gewindering abstützt, der an einem Flansch der Dose angreift. Bei den bekannten Dosen dieser Art ist der Dichtungsring zwischen dem Dosendeckel und dem Dosenflansch angeordnet. Da der Dosenmantel in der Regel eine Längsnaht hat, die bei Weißblechdosen gelötet ist, so ist der als Dichtrand dienende Dosenflansch an der Nahtstelle uneben und der Dichtungsring muß diese Unebenheit ausgleichen. Darin liegt bei diesen bekannten Dosen oftmals die Ursache eines nicht dichten Verschlusses. The invention relates to a can closure with a screw ring, which presses the can lid against a sealing ring and thereby attaches itself to a threaded ring supported, which engages a flange of the can. With the known doses of this The sealing ring is arranged between the can lid and the can flange. Since the can jacket usually has a longitudinal seam, which is soldered on tinplate cans is, the socket flange serving as the sealing edge is uneven at the seam and the sealing ring must compensate for this unevenness. Therein lies with these well-known Cans are often the cause of an imperfect seal.
Der Erfindung liegt nun die Aufgabe zugrunde, einen ebenen Dichtrand als Auflage für den Dichtungsring zu schaffen und dadurch die genannte Fehlerquelle auszuschließen: Dies wird gemäß der Erfindung im wesentlichen dadurch erreicht, daß der Dichtungsring zwischen dem Dosendeckel und dem mit dem Dosenflansch fest verbundenen Gewindering angeordnet ist. The invention is now based on the object of providing a flat sealing edge to create as a support for the sealing ring and thereby the aforementioned source of error to be excluded: According to the invention, this is essentially achieved by that the sealing ring is stuck between the can lid and the one with the can flange connected threaded ring is arranged.
Weitere Merkmale der Erfindung ergeben sich aus der nachfolgenden Beschreibung. Die Abbildung zeigt einen Schnitt in vergrößertem Maßstab durch einen Dosenverschluß gemäß der Erfindung. Further features of the invention emerge from the following Description. The illustration shows a section through an enlarged scale Can closure according to the invention.
Der Mantel 1 einer nur teilweise dargestellten Konservendose ist erfindungsgemäß an seinem oberen Ende zu einem Flansch 2 nach außen gebogen. Dieser Flansch ist nach einem weiteren Merkmal der Erfindung mit dem oberen, nach innen gebogenen Rand 3 eines Gewinderinges 4 durch Lötung bei 5 fest verbunden. Der Gewindering hat erfindungsgemäß ein dreigängiges Gewinde, von dem jeder Gewindegang 6 nur über ein Drittel des Ringumfanges verläuft. In der Abbildung ist deshalb nur einer der drei Gewindegänge 6 im Schnitt zu sehen. Der untere, ebenfalls erfindungsgemäß nach innen gebogene Rand 7 des Gewinderinges 4 liegt am Mantel I der Dose an. The jacket 1 is a can only partially shown according to the invention bent outwards at its upper end to form a flange 2. This According to a further feature of the invention, the flange is with the upper, inward curved edge 3 of a threaded ring 4 firmly connected by soldering at 5. The threaded ring according to the invention has a three-start thread, of which each thread turn 6 only over a third of the ring circumference runs. In the illustration there is therefore only one of three threads 6 can be seen in section. The lower one, also according to the invention inwardly curved edge 7 of the threaded ring 4 rests on the jacket I of the can.
Ein Schraubring8 stützt sich mit zweckmäßig gewindeartig ausgebildeten Einprägungen 9, von denen in der Abbildung nur eine von dreien im Schnitt zu sehen ist, an den Gewindegängen 6 des Gewinderinges ab und preßt den Dosendeckel IO gegen einen Dichtungsring II, der in bekannter Weise in den Deckelrand eingelegt ist. A screw ring8 is supported with appropriately designed thread-like Imprints 9, of which only one of three can be seen in section in the illustration is, on the threads 6 of the threaded ring and presses the can lid against IO a sealing ring II, which is inserted into the edge of the lid in a known manner.
Wie aus der Abbildung ersichtlich, ist der Dichtungsring II zwischen dem Dosendeckel 10 und dem Rand 3 des Gewinderinges 4 angeordnet. As can be seen from the figure, the sealing ring II is between the can lid 10 and the edge 3 of the threaded ring 4 are arranged.
Da der Gewindering in an sich bekannter Weise aus einem Stück hergestellt ist, liegt der Dichtungsring II auf dem ebenen Dichtrand 3 auf, so daß ein dichter Verschluß erzielt wird. Since the threaded ring is made from one piece in a manner known per se is, the sealing ring II rests on the flat sealing edge 3, so that a tight Closure is achieved.
Der Rand 3 des Gewinderinges und der Dosenflansch 2 haben erfindungsgemäß Kreisbogenform. The edge 3 of the threaded ring and the socket flange 2 have according to the invention Circular arc shape.
Diese Form ermöglicht eine einwandfreie Lötung dieser beiden Teile bei 5, die den Beanspruchungen beim Kochvorgang standhält.This shape allows these two parts to be soldered properly at 5, which withstands the stresses and strains of the cooking process.
Ein weiterer Vorteil der Kreisbogenform des Dichtrandes 3 liegt darin, daß diese das Offnen der Dose erleichtert. Das öffnen erfolgt durch Einschieben eines schraubenzieherartigen Gegenstandes zwischen dem Rand 3 und dem Dichtungsrand II. Another advantage of the circular arc shape of the sealing edge 3 is that that this makes it easier to open the can. It is opened by pushing it in a screwdriver-like object between the edge 3 and the sealing edge II.
Der Dichtrand 3 hat erfindungsgemäß einen Radius r von mindestens annähernd 2 mm. According to the invention, the sealing edge 3 has a radius r of at least approximately 2 mm.
