An injection mold with a centering device includes a die-holding plate with a cavity-forming die unit, a core-holding plate with a core unit, and a stripping plate between the core-holding and die-holding plates. The centering device has a insert and a mount with a clearance, which is rotationally symmetrical about a center axis and is for receiving the insert. The insert has an opening for receiving the core unit and the insert and the clearance of the mount are insertable in a torsion-free manner in the clearance of the mount in at least three positions rotatable about a center axis of the insert, and the center axis of the clearance and the center axis of the insert overlie one another. A center axis of the opening of the insert is arranged eccentrically in relation to the center axis of the insert by an offset. The centering unit is arranged in the stripping plate.

A cartridge for a medium to be dispensed includes a head part having a dispensing outlet and a film forming a cartridge wall, with the film surrounding a cartridge chamber for the medium to be dispensed, extending at least partially (along an axial extension) in a longitudinal direction of the cartridge and having a front end being connected to the head part. The film is preferably a multilayer film having at least two layers formed from different materials, and the front end of the film is sealingly and non-releasably embedded in the head part of the cartridge, so that an end face of the front end of the film is covered, in particular completely covered, by the head part.

The invention relates to a method for producing a syringe with an integrated closure element, which method comprises the following method steps: a) making available an injection moulding tool which comprises a first, a second and a third tool portion, wherein the first tool portion has a mould cavity open at both sides and extending along an axial direction (X), and wherein the second tool portion has a first injection moulding core and the third tool portion has a second injection moulding core; b) closing the injection moulding tool such that the first tool portion contacts the second and third tool portion, and the first and second injection moulding core each enter the mould cavity of the first tool portion through an opening and finally contact each other, as a result of which these tool portions form a first structural cavity; c) injecting a first plastic material into the first structural cavity, as a result of which a hollow cylindrical syringe body is formed with an end region at its distal end, wherein the end region has an attachment element, provided with an inner thread, and a hollow cylindrical endpiece which is at least partially bounded by the attachment element; d) cooling the tool portions, as a result of which the syringe body cools and hardens; e) bringing the first tool portion into contact with a fourth tool portion provided with a mould cavity closed at one end, as a result of which a second structural cavity is formed at the distal end of the syringe body; f) injecting a second plastic material into the second structural cavity, as a result of which the closure element is integrally formed on the attachment element, wherein the first and the second plastic material do not enter into a cohesive connection.

A mold adapted to manufacture a first molding element and a second molding element in different shapes or sizes is provided. The mold includes a first mold core, a second mold core and a filling component. The second mold core is capable of being arranged at the first mold core or separated from the first mold core. When the second mold core is arranged at the first mold core, a first mold cavity is formed between the first and second mold cores, and the shape of the first mold cavity corresponds to that of the first molding element. The filling component is detachably arranged in a local region of the first mold cavity. When the second mold core is arranged at the first mold core and the filling component is arranged in the first mold cavity, a second cavity is formed between the first mold core, the second mold core and the filling component, and the shape of the second mold cavity corresponds to that of the second molding element. In addition, a method of using a mold is also provided.
