Abstract: In the case of over-tightening of the closure-cap on a beverage bottle (through turning in the wrong direction) there is the risk that, due to the high internal pressure, not only will the thread jump, but also that the cap will be ejected directly from the container. In order to avoid this risk, the invention proposes a screwable closure-cap with security against over-tightening. This cap possesses a ramp element (3) on the end of the thread oriented towards the cap-base, said ramp element being able to engage with the thread-start of the container mouth in the case of over-tightening of the closure-cap. As a result, the cap-wall in the area of the ramp element will be forced outwards in the case of over-tightening so that jumping of the thread in this region will be facilitated. In this way, jumping of the thread on one side only--on the ramp element side--will be achieved when over-tightening is continued, so that ejection of the closure-cap will not be possible.
