ABSTRACT:
A closure arrangement of a container has fill socket with an inner thread and a closure cap with a cylindrical base body having an outer thread matching the inner thread of the fill socket of the container. The cylindrical base body has an annular flange adjacent to the outer thread. An annular seal, connected to one side of the annular flange facing the outer thread, is provided for sealingly resting on the rim of the fill socket when the closure cap is threaded into the fill socket. The outer thread has a resilient tongue extending in the circumferential direction of the cylindrical body and has a radial projection cooperating with the abutment of the matching inner thread. The radial projection, when the closure cap is threaded into the fill socket, catches in a catch position behind the abutment before a fully closed position of the closure cap in the fill socket is reached.
