Abstract

A closure cap for closing the pouring opening of a container, has a cylindrical threaded part with an open edge and an inner thread to interact with an outer thread of a container neck of the container, a security ring held on a protrusion on the container neck, a plurality of security webs releasably connecting the security ring to the open edge, a first holding strip with a first end rigidly connected to an open edge of the threaded part and a second end rigidly connected to the security ring, and a second holding strip with a third end rigidly connected to an open edge of the threaded part and a fourth end rigidly connected to the security ring. The second end on the circular path of the security ring is in a substantially diametrically opposed manner to the fourth end before the threaded part is opened for the first time.
