Closing cap for closing a container

Abstract

A closing cap for closing a container comprises a cylindrical threaded part having an open edge and an internal screw thread, which can interact with an external screw thread of the container neck. A tamper-proof strip is configured to be retained on an annular protrusion formed on the container neck. A retaining strip has a first and a second end and a first and a second edge. The first end is fixedly connected to the open edge of the threaded part, and the second end is fixedly connected to the tamper-proof strip. The first edge is detachably connected to the open edge of the threaded part by a predetermined breaking element, and the second edge is detachably connected to the tamper-proof strip by a second predetermined breaking element. The first predetermined breaking element and the second predetermined breaking element have different tensile strengths or tear strengths.
