METHOD FOR MANUFACTURING A CARTRIDGE FOR CONTAINING AND METERABLY DISPENSING A FLOWABLE DENTAL MATERIAL AND SUCH A CARTRIDGE

摘要

A method is for manufacturing a cartridge (10, 27, 30) for containing and meterably dispensing a reservoir (11) contained flowable dental material (36). The reservoir (11) is connected to a cannula section (14) for dispensing the dental material (36). A separate functional element (15) is connected to the cannula section (14). The cartridge (10, 27, 30) is manufactured together with the functional element (15) according to a multicomponent injection molding method. The functional element (15) is designed as a detachable closing element. The functional element (15) and the cartridge (10, 27, 30) are positioned during the manufacture such that the functional element (15) is mounted at least partially in the cannula section (14). The functional element (15) has a plug part (16) for closing the cannula section (14) and a cannula duct (24) of the cannula section (14) is filled at least partially with the plug part (16).
