When filling a container (90) of the first type, the liquid substance (99) coming out of the dispensing opening (30) is dispensed directly into the mouth (91) of the container (90) and flows onto an internal surface of a lateral wall of the container (90). When filling a container (95) of the second type, the liquid substance (99) coming out of the dispensing opening (30) flows onto the lateral wall (25) of the housing (2) and, after having entered the mouth (96) of the container (95), flows onto an internal surface of a lateral wall of the container (95).

A quick-change coupling is described for a container treatment machine, in particular a capping machine, with an outer member and an inner member engaging therewith in a positive-fit manner, between which members torques in a working direction of rotation and axial forces can be transmitted. Due to the fact that the outer member and the inner member are connectable to each other by pushing one into the other and twisting, a simple connection/separation of the quick-change coupling is possible without tools, as well as reliable and play-free transmission of unidirectional torques and contact pressure forces.
