Description
Bei den bekannten Deckelabdichtungen wird vielfach als Abdichtung eine in die Nut des Deckelrandes eingelegte Schnur mit rechteckigem, trapezförmigem oder rundem Querschnitt,, welche fest zwischen Deckelrand und Kastenwand gepreßt wird, verwandt. Bei einer andern Ausführung hat diese Schnur U-förmigen Querschnitt, wobei die Schenkel nach unten zeigen. Das Einführen dieser Art Deckel in das Gefäß ist nur dann möglich, wenn die Schnur am ganzen Umfang entlang so weit zusammengedrückt worden ist, was mit Hilfe einer besonderen Vorrichtung geschehen müßte, daß der Umfang des Deckels einschließlich Schnur kleiner ist als die Gefäßöffnung. Das Einbringen aller dieser Deckel bis auf die Auflageflächen in der Zelle ist schwierig, da infolge der an der Wandung des Gefäßes auftretenden Reibung der Deckel wieder zurückfedert, nachdem er bereits aufgelegen hat.In the known cover seals is often used as a seal in the Groove of the lid edge inserted cord with a rectangular, trapezoidal or round cross-section, which firmly between Lid edge and box wall is pressed, related. In another version has this cord U-shaped cross-section, with the legs pointing downwards. Introducing This type of lid in the vessel is only possible if the cord is compressed so far along the entire circumference has been what would have to be done with the help of a special device that includes the scope of the lid Cord is smaller than the opening of the vessel. Bringing in all of these lids except for the bearing surfaces in the cell is difficult because of the on the wall of the vessel Occurring friction springs back the lid after it has already been placed Has.
Nach der Erfindung wird diesen Übelständen dadurch abgeholfen, daß als Dichtungsring ein Gummiband mit einem zungenartig ausgebildeten Kranz verwendet wird. Der Umfang der Außenkante der Schnur einschließlich Deckel ist größer als der Umfang der Kastenöffnung. Das Einsetzen des Deckels geht ohne Schwierigkeit vor sich. Der verhältnismäßig dünne ausgebildete Rand des Gummiringes biegt sich dabei um und legt sich leicht gegen die Innenwand des Kastens, wo er abdichtet und den Deckel nicht zurückfedern läßt, sondern festhält.According to the invention, these inconveniences are remedied in that as a sealing ring a rubber band with a tongue-like ring is used. The circumference of the outside edge of the cord including Lid is larger than the circumference of the box opening. The insertion of the lid goes on without difficulty. The relatively thin formed edge of the rubber ring bends over and easily lies against the inner wall of the Box, where it seals and does not let the lid spring back, but holds it tight.
Im Bedarfsfall kann der Deckel über dem Dichtungsring mit einem vorstehenden Rand, der auf dem Kastenrand aufliegt, versehen sein. Statt eines geschlossenen Randes genügen natürlich auch einzelne Ansätze an dem Deckel, die ebenfalls eine sichere Auflage bewirken können.If necessary, the cover can be fitted over the sealing ring with a protruding edge, which rests on the edge of the box, be provided. Instead of a closed edge, it suffices Of course, there are also individual approaches to the lid, which also provide a secure support can cause.
Die Zeichnung zeigt als Beispiel vier Ausführungsformen der Dichtung nach der Erfindung im senkrechten Schnitt. 4SThe drawing shows as an example four embodiments of the seal according to the invention in vertical section. 4S
