  • Patent number: 4952209
    Abstract: Applicator syringe for a dental compound, with a syringe body (1) tapering into a thin discharge tube (3) and with a piston (5) displaceable in it, the applicator syringe being intended for once-only use. To avoid the need for special actuating tools, but make easy use possible, the effective cross-sectional surface is very small, in particular with a ratio of the useful stroke to the diameter of the syringe piston of at least approximately 10. So that the syringe can nevertheless be filled easily, the diameter of the cylindrical space in the rear portion of the latter is larger than the piston diameter. The syringe body (1) is first produced in a straight form and only thereafter is the discharge tube (3) bent.
