A dosing device is provided and comprises a withdrawal container and a dosing means comprising at least one dosing unit which is a piston-cylinder unit designed as a disposable member. The piston-cylinder unit discharges into a receiving container and valve means is provided to control flow into and out of the piston-cylinder unit.

Metering device and method for operating a metering device

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.

Syringe metering unit for bottle top dispenser

The bottle top dispenser has a valve housing and a piston-cylinder unit, which can be releasably affixed to the housing, the piston and cylinder of which can be activated in an axial stroke movement relative to one another, in order to draw liquid from a bottle on which the dispenser is set, and eject it. The intake process takes place in a spring-activated extension movement, and the ejection process takes place in a manually activated compression movement of the piston-cylinder unit. The dispenser has an activation unit, where a releasable activation connection can be produced between the former and the piston-cylinder unit. The activation unit is provided with the spring element for the intake process, and preferably designed for the manual action for ejection.
