Description

Gegenstand der Erfindung ist die Anordnung einer Dichtung an einem doppelwandigen Metallgefäß; der Außenmantel des Metallgefäßes ist bis an den Fuß des Spundkragens geführt, der durch Ziehen des Innenmantels gebildet ist Doppelwandige Metallgefäße, bei denen der Innenhehälter meist aus hochwertigem oder weniger widerstandsfähigem Material besteht, erhalten bekanntlich als Außenmantel oder als Abdeckung der Böden eine Stahlblechverkleidung. Bei derartigen Behältern wird der Spundverschluß im Hinblick auf das empfindliche oder aggressive Füllgut als Kappenverschluß ausgebildet, indem der Innenmantel als Spundkragen über den Spundring gezogen ist und danach die Verschluß dichtung sich auf den Gefäß mantel selbst abstützt. Der Spundring stützt sich dann auf den Außenmantel aus Stahl ab. Dies hat den Nachteil, daß bei Entnahme des Füllgutes, beispielsweise aggressive Füllstoffe, dieser zwischen Spundring und Außenmantel, insbesondere aber zwischen Stahlaußen- und Stahlinnenmantel, gelangt. Besteht beispielsweise der Innenmantel aus Aluminium, dann wird in verhältnismäßig kurzer Zeit die Korrosion so stark sein, daß eine vollständige Zerstörung des Gefäßmantels eintritt. The invention relates to the arrangement of a seal on a double-walled metal vessel; the outer jacket of the metal vessel extends to the foot out of the bung collar, which is formed by pulling the inner jacket double-walled Metal vessels, in which the inner container is usually made of high quality or less resistant Material consists, as is well known, obtained as an outer jacket or as a cover for the floors a sheet steel cladding. In such containers, the bung lock is in Designed as a cap closure with regard to the sensitive or aggressive filling material, by pulling the inner jacket over the bung ring as a bung collar and then the closure seal is supported on the vessel jacket itself. The bung ring is then based on the steel outer jacket. This has the disadvantage that at Removal of the filling material, for example aggressive fillers, this between the bung ring and outer jacket, but especially between the steel outer jacket and the steel inner jacket. If, for example, the inner jacket is made of aluminum, then it is relatively In a short time the corrosion will be so severe that the vessel jacket will be completely destroyed entry.

Diesem Nachteil begegnet die Erfindung dadurch, daß zwischen Spundring und Außenmantel eine Dichtung eingefügt wird. Damit ist der Zulauf von Füllgut zwischen Außen- und Innenmantel unterbunden. Außerdem bewirkt die zwischen Spundring und Außenmantel eingefügte Dichtung, die zweckmäßig bis an den Fuß des Spundkragens reicht, eine elastische Verbindung zwischen Spundkragen und Spundring, die den hochgezogenen und damit geschwächten Werkstoff gleichzeitig schont. The invention counteracts this disadvantage in that between the bung ring and a seal is inserted into the outer jacket. This means that the supply of filling material is between Outer and inner jacket prevented. In addition, the effect between the bung ring and Outer jacket inserted seal, which expediently to the foot of the bung collar is enough, an elastic connection between the bung collar and the bung ring that the raised and at the same time protects the weakened material.

In der Zeichnung ist ein Teilquerschnitt durch den Spundverschluß gemäß der Erfindung dargestellt. The drawing shows a partial cross-section through the bung seal shown according to the invention.

Über den Spundkragen 7 ist der Spundring 2 geschoben, und das freie Ende des Spundringes 2 ist dann auf den Spundring 2 gebördelt. Zwischen dem umgebördelten Teil des Spundkragens 7 und der Spundkappe 4 ist eine Dichtung 3 vorgesehen. Zwischen Außenmantel 5 und Spundring 2 ist die Dichtung 6 eingefügt, die den flüssigkeitsdichten Verschluß zwischen Außen- und Innenmantel gewährleistet. Die Dichtung 6 preßt sich dabei abdichtend sowohl gegen den Spundkragen7 und gegen den Außenmantel 5. The bung ring 2 is pushed over the bung collar 7, and the free one The end of the bung ring 2 is then flanged onto the bung ring 2. Between the beaded Part of the bung collar 7 and the bung cap 4, a seal 3 is provided. Between Outer jacket 5 and bung ring 2, the seal 6 is inserted, the liquid-tight Closure between the outer and inner jacket guaranteed. The seal 6 is pressed thereby sealing both against the bung collar 7 and against the outer jacket 5.

PATENTANSPROCHE: I. Spundverschluß mit einer Dichtung zwischen Mantel und Spundring und einem durch Hochziehen des Innenmantels gebildeten Spundkragen, dessen freies Ende auf den Rand des über den Spundkragen gestreiften Spundringes umgebördelt ist, dadurch gekennzeichnet, daß der Außenmantel (5) bis an den Fuß des Spundkragens (7) geführt und zwischen Spundring (2) und Außenmantel (5) eine Dichtung (6) vorgesehen ist. PATENT APPEAL: I. Bung lock with a seal between the jacket and bung ring and a bung collar formed by pulling up the inner jacket, its free end on the edge of the bung ring that is striped over the bung collar is flanged, characterized in that the outer jacket (5) up to the foot of the bung collar (7) and between the bung ring (2) and outer jacket (5) a Seal (6) is provided.
