US Patent 6848906 Syringe for the metered delivery of dental materials

The invention relates to a syringe for delivering flowable and/or highly viscous materials with a syringe tube, which has an outlet nozzle, a material container, which is disposed therein, a handle, which is disposed at the end of the syringe tube opposite to the outlet nozzle, and a syringe piston, which can be moved through the handle into the syringe tube. A safe operation is assured, even when larger pressures are exerted, owing to the fact that the handle is connected by means of a thread to the syringe tube and the material container has a closed lateral surface around the axis.
