A closure cap for closing the pouring opening of a container includes a cylindrical threaded part which has an open rim, a first cylindrical shell, and an internal thread, which is formed on the interior of the shell and can interact with an external thread of a container neck delimiting the pouring opening; a security ring, which is designed to be held on a projection formed on the container neck. The closure cap includes a first retaining strip having a first and a second end, wherein the first end is rigidly connected to the open rim of the threaded part and the second end is rigidly connected to the security ring; and a second retaining strip, having a third and a fourth end, wherein the third end is rigidly connected to the open rim of the threaded part and the fourth end is rigidly connected to the security ring.

Closure cap

A plastic container closure has a screw cap with a cylindrical casing having an internal screw thread and a lid disc adjoining the casing, a security ring connected by first break-off webs to a free edge of the casing and a holding ring in the region of the container neck. The security ring has slots distributed over its circumference and each have a top edge and a bottom edge, wherein the top edge is formed by a section of the security ring that extends in the shape of a circular arc. The bottom edge is formed by a wall section that is inclined inwards in a radial direction. The bottom edge of each slot engages in a form-fitting manner with the holding ring.
