Abstract
A drug delivery device comprises a housing adapted to receive a medicament container, a plunger and a plunger release mechanism that comprises a first plunger boss arranged on the plunger, a profiled slot arranged on the housing and adapted to be engaged by the first plunger boss so as to inhibit movement of the plunger in a distal direction. The plunger is rotatable about a longitudinal axis to release the first plunger boss from the profiled slot so as to allow movement of the plunger in the distal direction. A sleeve is coupled to the housing to permit movement of the sleeve relative to the housing. A sleeve ramp is arranged on the sleeve and adapted to engage a rib or boss on the plunger to rotate the plunger to release the first plunger boss from the profiled slot when the sleeve is moved in a proximal direction.
