1. A cap assembly for a drug delivery device, comprising:
a cap body adapted to receive a needle assembly to be releasably interconnected with a housing of the drug delivery device, and an ejector unit movably arranged on the cap body at least along the body's long axis and comprising a mechanical transmission means adapted to transfer at least an axial displacement of the ejector unit to the needle assembly for ejecting the needle assembly from the cap body, wherein the ejector unit is slidably arranged on an outer circumference of a proximal end section of the cap body, wherein the ejector unit is at least displaceable into an ejecting position to eject the needle assembly from the cap body, wherein, in the ejecting position, the ejector unit at least partially protrudes in a proximal direction beyond a proximal end of the cap body, wherein the cap body comprises an annular groove at an inside facing portion of its sidewall to releasably engage with the housing of the drug delivery device, and wherein the cap body comprises a cupped receptacle for selectively receiving at least a portion of a cartridge holder or body of the drug delivery device.
