Patent ID: 8177759

Claim:
A medicament delivery device, comprising: a generally tubular distal housing part; a generally tubular proximal housing part releasably connected to the distal housing part; a medicament container having opposite proximal and distal ends and a slidable stopper, wherein the container is partially and slidably arranged within the proximal housing part; a plunger rod having opposite proximal and distal ends and being arranged within the distal housing part, wherein the proximal end of the plunger rod abuts the stopper; a drive mechanism arranged within the distal housing part and operably connected to the plunger rod for driving the plunger rod and thereby the stopper toward a proximal end of the device; a priming device having a distal end comprising a tune engagement mechanism arranged to cooperate with a corresponding tune engagement mechanism arranged at the proximal housing part, an end wall abutting the proximal end of the container, a passage arranged on the end wall, and a proximal end comprising a delivery member engagement mechanism arranged to cooperate with a corresponding delivery member engagement mechanism arranged on a delivery member; wherein the priming device is arranged such that a tune distal displacement of the priming device in relation to the proximal housing part causes a distal displacement of the container in relation to the plunger rod, whereby the plunger rod forces the stopper to be proximally displaced, thereby priming the container; and at least one priming locking device releasably connected to both the priming device and the proximal housing part for locking the priming device to the proximal housing part.
