Abstract
The invention relates to a package for liquid made of a coated cardboard composite, having a pierceable opening for a drinking straw, which has incisions 11 running towards one another in the form of rays or a star, and perferably a cutout 9 located at the star point of the incisions. An opening thus constructed for a drinking straw easily enables an arbitrarily concentric expansion of the star flaps located between the incisions, so that said flags rest sealingly on the drinking straw in each case. This guarantees for different drinking straws a uniform opening for the drinking straw which can be introduced into the multilayer cardboard composite both before it is coated and after it is coated.
