Abstract
A dispensing device for a dental material includes a cartridge having an outlet nozzle which forms a passageway for the dental material. The dispensing device further includes a closure which is placeable on the outlet nozzle for sealing the cartridge. The closure includes a pin for extending into the passageway, and is further adapted to seal with an outer surface of the outlet nozzle. The dispensing device is further adapted such that the pin is displaceable from the passageway by dental material dispensed from the cartridge, where the displacement causes the closure to release from the outlet nozzle. The invention may provide for relatively easy operation of the dental dispensing device.
