A container having a screw cap and a lower closure member to be connected to the container opening by a base member with a pouring spout connected thereto by an extendible bellows. The screw cap is adapted to be screwed onto and off the pouring spout. In order to render the closure childproof the pouring spout of the lower closure member, beyond its external thread, in a transitional region directed towards the bellows, carries a catch projection, which in the screwing-on direction comprises a gradually rising flank and merges into a steep flank. The cap side wall in the fully screwed-on position is in positive engagement with the catch projection and prevents unscrewing of the screw cap. By pressing inwardly the bellows in the region of the catch projection, the positive engagement between the screw cap and the pouring spout is cancelled and the screw cap is released for being unscrewed.
