Abstract

A syringe made of plastic serves as a metering part for a bottle-top dispenser. It includes a piston-cylinder unit, which has a cylinder sleeve with an installation opening for the piston, and a retainer ring for the piston which lies in front of the installation opening and which is clipped onto the cylinder sleeve in such a way that the piston cannot be pulled out of the cylinder.
