An injection device for injection of a medicament from a container (10) through a needle (16) disposed at the distal end of the container (10) is disclosed. The container (10) has a container body (12) and a stopper (22) for containing the medicament in the container body (12), and the device comprises a housing (110), a plunger (300) for driving the stopper (22) of the container in a distal direction to expel the medicament through the needle (16), a drive mechanism (330) arranged to move the container (10) relative to the housing from a starting position in which the needle (16) is shrouded to an insertion position in which the needle (16) is exposed, a carrier (220) for receiving the container body (12), the carrier (220) being guided for axial movement with respect to the housing (110; 510), an interlock component (250) arranged for movement from a first position to a second position, and a carrier lock arrangement (232, 124, 256) arranged to lock the carrier (220) in an initial axial position relative to the housing (110) when the interlock component (250) is in the first position, and to release the carrier (220) from the initial axial position upon movement of the interlock component (250) towards the second position. |
