Abstract

The invention relates to a container seal with a sealing body which can be punctured for supplying or removing liquids to or from a container (3) by means of a blunt hollow needle (10), this sealing body consisting at least partially of a highly elastic material in which a cut is made at the puncture point (23) through at least 75% of its thickness. The seal can in this case be designed independently in the form of a stopper or as a small insert plate for a seal.
