Abstract

A plastic wide-neck drum produced by the blow-moulding process with a clamping ring lid closure and with a blow-moulded flange ring extending radially outwards and lid with an inserted elastic sealing ring which is pressed against the upper edge of the opening neck with a plastic clamping ring. In contrast to the metal clamping ring, the elastic plastic clamping ring can be restored to its original shape after deformation. If a full drum is dropped and lands on the edge of the drum lid, the metal clamping ring springs off and the lid edge region is deformed. The elastic plastic clamping ring adapts to the temporary deformation and is restored with the drum lid edge region. This results in greater resistance to dropping. Figure 1 shows an inserted and welded inner ring (11) in a plastic construction, which closes the hollow groove (15). <IMAGE>

Description

Die Erfindung bezieht sich auf ein Kunststoff-Faß, das mit einem Deckel und einem Spannring verschließ­ bar ist; entsprechend den Merkmalen des Patentanspruchs.The invention relates to a plastic barrel, that closes with a lid and a tension ring is cash; according to the features of the claim.

Bei derartigen, zumeist aus Kunststoff geblasenen Fässern, wie sie z. B. aus der DE-AS 22 58 096 und der DE-25 44 491 bekannt sind, besteht das Problem, die Dichtigkeit des Verschlusses zwischen Faß und Deckel auch dann zu gewährleisten, wenn ungewöhnliche Belastungen auftreten, wie dies z. B. beim Umstürzen oder Fallen des Fasses aus größerer Höhe der Fall ist. Dieses Problem stellt sich für die in Rede stehenden Kunststoff-Fässer vor allem deshalb, weil sie häufig zum Transport von flüssigen Chemikalien Verwendung finden, deren Austritt z. B. bei Fahrzeugunfällen gefährlich wäre, besonders wenn es um Gefahrgüter geht. In such, mostly blown from plastic Barrels such as B. from DE-AS 22 58 096 and known from DE-25 44 491, there is the problem the tightness of the closure between the barrel and Ensure lid even when unusual Loads occur, such as this. B. when falling or the barrel falls from a greater height. This problem arises for those in question Plastic barrels mainly because they are common for transporting liquid chemicals find whose exit z. B. in vehicle accidents would be dangerous, especially when it comes to dangerous goods goes.  

Man hat sich mit diesem Problem schon mehrfach beschäftigt, ohne allerdings eine den gestellten hohen Anforderungen, vor allem in bezug auf Fall­ festigkeit, restlos zufriedenstellende Lösung ge­ funden zu haben.This problem has been dealt with several times busy, but without the one posed high demands, especially in relation to case strength, completely satisfactory solution to have found.

So hat man vorgeschlagen, die Faßbordur aus einem von der Behälterwand radial nach außen vorstehenden Mantelflansch auszubilden, und der Deckel einen am unteren Rand angeformten Außenflansch aufweist; der den Spannring übergreift.So it has been suggested that the barrel border be made from one projecting radially outward from the container wall Form flange, and the lid one on has formed on the lower edge of the outer flange; the engages over the clamping ring.

Beim Absturz eines gefüllten Fasses und beim Auftreffen auf die Randkante des Deckels wird der Metall-Spann­ ring abgesprengt, auch bleibend verformt, so daß der Dichtungssitz des Deckels zerstört wird.When a filled barrel falls and when it hits it the metal clamp is on the edge of the lid ring blasted off, also permanently deformed, so that the sealing seat of the cover is destroyed.

Aufgabe der Erfindung ist es daher, für ein Kunst­ stoff-Faß der angegebenen Art einen Verschluß zu finden, der auch bei hohen Belastungen die geforderte Dichtigkeit zwischen Faß und Deckel aufrecht erhält.The object of the invention is therefore for an art cloth barrel of the specified type to a closure find the one that is required even under high loads Maintains tightness between barrel and lid.

Hierzu sieht die Erfindung die im Kennzeichen des Patentanspruchs angegebene Ausbildung des Kunststoff- Spannrings vor.To this end, the invention provides the characteristics of Training specified the plastic Clamping ring in front.

Wie sich bei Versuchen gezeigt hat, läßt sich mit dem erfindungsgemäßen Spannring aus Kunststoff ein wesent­ lich besseres Abfangen der auftretenden Stoßbelastungen erreichen. Diese Erkenntnis wird vor allem durch das dem Kunststoff eigene Rückstellvermögen unter­ strichen. Außerdem entfallen die bleibenden Defor­ mierungen am Faßhals und Deckel, die ansonsten durch den Metall-Spannring eingefroren werden; wodurch im Extremfall der Deckel auch ganz vom Faß abspringen kann.As has been shown in experiments, the Clamping ring made of plastic according to the invention an essential better interception of the shock loads that occur  to reach. This knowledge is mainly through the resilience inherent in plastic deleted. In addition, the permanent Defor are eliminated Gems on the barrel neck and lid, otherwise be frozen by the metal clamping ring; in extreme cases, the lid is also completely Barrel can jump off.

Der erfindungsgemäße "weiche" Kunststoff-Spann­ ring ermöglicht bei einer vorrübergehenden Deformation des Fasses oder Deckels ein Mitvoll­ ziehen dieser Deformation und gewährleistet eine stets formschlüssige Verbindung zwischen Faß und Deckel.The "soft" plastic instep according to the invention ring allows for a temporary Deformation of the barrel or lid a full pull this deformation and ensures a always positive connection between barrel and Cover.

Der Gegenstand der Erfindung wird nachstehend anhand einer Zeichnung noch näher erläutert; in der Zeichnung zeigtThe subject of the invention is as follows explained in more detail with reference to a drawing; shows in the drawing

Fig. 1 einen Teilquerschnitt von Faßhals mit auf­ gesetzten Deckel, Spannringprofil und ein­ geschweißten Kunststoffring. Fig. 1 shows a partial cross section of the barrel neck with a lid, clamping ring profile and a welded plastic ring.

In der Zeichnung bezeichnet 1 den am oberen Ende eines Faßkörpers befindlichen und die Faßöffnung bildenden Faßhals, während der Deckel, zum Ver­ schließen der Faßöffnung, mit 2 bezeichnet ist.In the drawing, 1 denotes the barrel neck located at the upper end of a barrel body and forming the barrel opening, while the lid, for closing the barrel opening, is designated 2 .

Der Faßkörper mit dem Hals 1 ist vorzugsweise einstückig aus Kunststoff geblasen, und auch der Deckel 2 besteht vorzugsweise aus Kunststoff. Zweckmäßig haben Faßkörper und Faßdeckel die gleichen physikalischen und mechanischen Eigen­ schaften.The barrel body with the neck 1 is preferably blown in one piece from plastic, and the cover 2 is also preferably made of plastic. Conveniently, barrel body and barrel lid have the same physical and mechanical properties.

Der zur Verwendung kommende Kunststoff für den Spannring 12 hat höhere Kristallinität, höhere Dichte und ist härter als der Faß- und Deckel- Kunststoff.The plastic used for the clamping ring 12 has higher crystallinity, higher density and is harder than the barrel and lid plastic.

Zwischen der Dicke des radialen Ringmantels und den beiden Enden der parallelen Spannringschenkel besteht eine Maßabhängigkeit.Between the thickness of the radial ring jacket and the two ends of the parallel clamping ring legs there is a dimensional dependency.
