Abstract
A syringe, in particular for viscous or liquid dental materials, provided with a syringe housing 12, in which a plunger 22 is guided for displacement in a manner known, wherein the plunger 22 can be removed from the syringe housing 12 and introduced into the syringe housing 12, and with an outlet cannula 20, which is fitted on the syringe housing 12. A region of the syringe housing 12 which is adjacent to the outlet cannula 20 is of deformable design and a region of the syringe housing 12 which is remote from the outlet cannula 20 is of dimensionally stable design.

Syringe for viscous or liquid dental materials comprising
- a syringe housing (12),
- a plunger (22) disposed in the syringe housing and guided in the syringe housing for displacement,
- wherein the plunger (22) can be removed from the syringe housing (12) and introduced into the housing, and
- an outlet cannula (20) fitted on the syringe housing (12),
- wherein the syringe housing (12) comprises an outer housing and an inner compressible housing,
- wherein the outer housing comprises a dimensionally stable region which is remote from the outlet cannula (20) and a deformable region which is adjacent to the outlet cannula (20),
- wherein the dimensionally stable region is not capable of being deformed,
- wherein the outer housing extends outside and around the inner compressible housing,
- wherein the inner compressible housing extends the complete length of the syringe housing (12) in which the plunger (22) is guided in the syringe housing 12, and
- wherein the inner compressible housing is insertable into the outer housing.
