Method and apparatus for producing primary packaging having an integrated septum and primary packaging having an integrated septum

A method for producing primary packaging having an integrated septum comprising the steps of:

• a) providing a septum,
• b) providing an injection-molding die having two die halves able to be moved relative to one another, wherein one die half comprises a holder for the septum, and the other comprises a stamp,
• c) positioning the septum in the injection-molding die,
• d) moving the two die halves of the injection-molding die such that a cavity is formed that corresponds to the shape of the primary packaging to be produced,
• e) injecting a material into the cavity in the injection-molding die via an injection opening in one of the die halves of the injection-molding die, the two die halves of the injection-molding die pretensioningly holding the septum therebetween, and a rim of the septum being overmolded by the material, a region of the septum in contact with the two die halves remaining free of material, wherein the septum is at least partially arranged between the stamp and the holder, and the stamp and the holder are pressed against the septum when the material is injected via an injection opening such that the septum is in a pretensioned state, wherein the septum is also overmolded with material from the front thereof and only the region of the septum in which the stamp and the holder press against one another remains free of the material,
• f) cooling the injected material while maintaining a holding pressure, as a result of which the primary packaging is formed having an integrated septum,
• g) moving the two die halves of the injection-molding die such that the produced primary packaging having the integrated septum is removable from the injection-molding die, and
• h) removing the produced primary packaging having the integrated septum from the injection-molding die.
