In one aspect the present disclosure relates to an injection device. The injection device includes a housing configured to receive a container; a drive mechanism having a plunger configured to urge against a bung in the container in a distal direction to expel the dose of the medicament from the container, wherein the plunger is configured to releasably connect to the bung to form a plunger bung assembly; a container moving mechanism configured to move the container relative to the housing between a proximal replacement position and a distal injection position; at least one retainer configured to prevent a proximally directed movement of the container relative to the housing. The drive mechanism is configured to retract the plunger and the plunger bung assembly along the proximal direction relative to the tubular barrel of the container.
