Abstract

Ein Drehverschluss zum Verschliessen von unter Innen­ druck stehenden Behältern hat eine Behältermündung (1) mit einem Aussengewinde (2) und eine Schraubkappe (3) mit Innengewinde (4). Die Schraubkappe weist eine Dichtpartie (5) auf, welche mit der Behältermündung dichtend in Eingriff bringbar ist. Um beim Aufschrauben der Schraubkappe eine Abdichtung am Schraubgewinde und damit die Gefahr eines Wegsprengens der Schraubkappe zu vermeiden, sind auf den Gewindeflanken Distanznocken (7) angeordnet, welche die Gewindeflanken derart in einer Relativlage zueinander halten, dass zwischen den Flanken ein Entlüftungskanal (11) entsteht. Dadurch wird der Innendruck im Behälter beim Aufschrauben der Schraubkappe zuverlässig über das Ge­ winde abgebaut, solange dieses noch fest im Eingriff ist. A twist lock for closing from the inside pressurized containers has a container mouth (1) an external thread (2) and a screw cap (3) Internal thread (4). The screw cap has a sealing section (5), which sealingly engages with the container mouth is feasible. To a when screwing on the screw cap Sealing on the screw thread and thus the risk of To prevent the screw cap from bursting open the thread flank spacer cams (7) which the thread flanks are in a relative position to each other keep a ventilation channel (11) between the flanks arises. This will reduce the internal pressure in the tank Screw the screw cap reliably over the Ge winch dismantled as long as it is still firmly engaged.
