The dispensing device serves for discharging a free-flowing medium from a container. An insert arranged in the container neck and filling the clear cross-section of the latter has a design suitable for discharging the free-flowing medium. The insert resting on the container neck is held firm by a catch having a bead on the container neck and a groove on the insert. In the case of a container intended for refilling, this catch can be overcome and the insert can be pulled out from the container neck by a cam projecting radially on the inside of the screw cap and engaging behind the end flange. If reuse of the container is to be ruled out, the cam on the cap is absent. In the case of a modified embodiment, the bead extending into the groove and the groove itself are dimensioned to be of different sizes in the radial direction. If the bead is dimensioned to be larger, the catch cannot be overcome. |
