ABSTRACT:
The invention deals with an end face (1) with tear-away lip closure (3) for a pressurized container. Upon opening the tear-away lip (3), often the contents of the container are sprayed around because of the high internal pressure and the formation of foam after shaking the container. To remedy this disadvantage of known containers, a throttle device (5) for controlled release of the excess pressure is applied over the hole which is formed on tearing open the first section of the lip closure (3). This throttle device can be applied to both lip closures which are completely removed from the end face, as well as lip closures which stay attached to the end face and which are pushed into the inner space of the container.
