Dental capsule or cartridge with frangible end seal

摘要

A dental capsule or cartridge for packing, storing and dispensing a dental filling material and the like having a body portion for containing a predetermined amount of dental material having a discharge nozzle connected at one end of the body portion and having the other end opened and sealable by a displaceable piston. A sealing cap is integrally formed at the discharge end of the discharge nozzle and is connected thereto by a frangible or weakened portion whereby upon the application of a breaking force, the sealing cap is readily separated from the discharge end of the nozzle to expose or form the discharge orifice. The sealing cap may also be provided on one end thereof with a cavity or sealing spike by which the discharge orifice may be resealed, if desired. A vent is also provided adjacent the open end of the capsule to facilitate the filling of the capsule, and which is sealed by the seating of the displaceable piston in the open end.
