1. Closure cap for closing the pouring opening of a container, comprising:
a cylindrical threaded part having an open edge and an inner thread, configured to interact with the outer thread of a container neck of the container,
a security ring configured to be held on an annular protrusion on the container neck,
a plurality of security webs releasably connecting the security ring to the open edge,
a first holding strip having a first end and a second end and a first edge and second edge, wherein the first end is rigidly connected to the open edge of the threaded part, and the second end is rigidly connected to the security ring, and
a second holding strip having a third end and a fourth end and a third edge and fourth edge, wherein the third end is rigidly connected to the open edge of the threaded part, and the fourth end is rigidly connected to the security ring,
wherein the second end is arranged on a circular path of the security ring substantially diametrically opposite the fourth end before the threaded part is opened for a first time, and
wherein in the closed state of the threaded part, the first and the third ends enclose a first opening angle of at least 170 degrees and at most 190 degrees, or at least 175 and at most 185 degrees, with respect to the center point of the closure cap as an apex, and
