A kit of injection devices, the kit comprising a first injection device and a second injection device,
- wherein the first injection device comprises:
- a housing of a drug delivery device, the housing comprising:
- a first housing component comprising a first connecting end provided with a fastening element, the first housing component being shaped and configured to accommodate a medicament container, the medicament container comprising a mechanical coding and an alignment element,
- a second housing component configured to accommodate a drive mechanism of the drug delivery device and comprising a second connecting end provided with a counter fastening element complementary shaped to the fastening element, the second connecting end being connectable to the first connecting end,
- a counter alignment element complementary shaped to the alignment element and provided in or on the first housing component, and
- a mechanical counter coding provided in or on the second housing component, wherein when the medicament container is arranged in the first housing component and when the mechanical coding does not match the mechanical counter coding, the mechanical coding and the mechanical counter coding are operable to prevent an engagement of the fastening element with the counter fastening element;
- the medicament container comprising:
- a barrel sized and configured for insertion into the first housing component of the housing,
- the alignment element on the barrel sized and shaped to engage with the counter alignment element of the first housing component when the barrel is inserted in a longitudinal direction into the first housing component, and
- the mechanical coding on the barrel sized and shaped to engage with the mechanical counter coding of the second housing component when the first housing component with the barrel arranged inside is connected to the second housing component, wherein the medicament container is arranged inside the first housing component;
- and
- the drive mechanism arranged inside the second housing component;
- wherein the second injection device comprises:
- a further housing of a further drug delivery device, the further housing comprising:
- a further first housing component comprising a further first connecting end provided with a further fastening element, the further first housing component being shaped and configured to accommodate a further medicament container, the further medicament container comprising a further mechanical coding and a further alignment element,
- a further second housing component configured to accommodate a further drive mechanism of the further drug delivery device and comprising a further second connecting end provided with a further counter fastening element complementary shaped to the further fastening element, the further second connecting end being connectable to the further first connecting end,
- a further counter alignment element complementary shaped to the further alignment element and provided in or on the further first housing component, and
- a further mechanical counter coding provided in or on the further second housing component, wherein when the further medicament container is arranged in the further first housing component and when the further mechanical coding does not match the further mechanical counter coding, the further mechanical coding and the further mechanical counter coding are operable to prevent an engagement of the further fastening element with the further counter fastening element;
- the further medicament container comprising:
- a further barrel sized and configured for insertion into the further first housing component of the further housing,
- the further alignment element on the further barrel sized and shaped to engage with the further counter alignment element of the further first housing component when the further barrel is inserted in a further longitudinal direction into the further first housing component, and
- the further mechanical coding on the further barrel sized and shaped to engage with the further mechanical counter coding of the further second housing component when the further first housing component with the further barrel arranged inside is connected to the further second housing component, wherein the further medicament container is arranged inside the further first housing component;
- and
- the further drive mechanism arranged inside the further second housing component;
- wherein one of the mechanical coding and the mechanical counter coding of the first injection device distinguishes from the further mechanical coding or the further mechanical counter coding of the second injection device with regard to at least one of:
- a number of coding features or counter coding features,
- a circumferential position of the coding features relative to the alignment element on the barrel,
- a circumferential position of the counter coding features relative to the counter fastening element,
- a circumferential extent of the coding features or the counter coding features,
- a radial extent of the coding features or the counter coding features, and
- a cross-sectional geometry or shape of the coding features or the counter coding features in a plane transverse to the longitudinal direction.
