Abstract

In a method for the manufacture of a cartridge, in a first step, a storage chamber for the reception of a filler material, a neck which contains an outlet passage for the filler material, and a closure stopper are manufactured in a single workstep in an injection molding process. The outlet passage has an end, wherein an outlet opening is arranged at the end of the outlet passage. The closure stopper has an arm, wherein the outlet opening is held at least partly closed by the arm of the closure stopper. The arm has a first end, wherein the first end of the arm is connected to the neck by a bridge element. A desired break point is formed by the bridge element and the closure stopper is connected to the cartridge in one piece via the bridge element. The closure stopper has a second end, wherein, in a second subsequent step, the bridge element is cut by manipulation of the second end before the filling of the cartridge with the filler material and subsequently the arm is introduced into the outlet opening to close the outlet opening. A cartridge is furthermore shown which is manufactured in accordance with this method.
