#$%^&*AU2013204406B220150709.pdf#####AUTOMATIC INJECTION DEVICE Abstract A syringe plunger (700') is formed of a polymeric material. The syringe plunger includes a pressurizer (754') disposed at a proximal end, and a distal end bifurcated into a first plunger arm (788a') having a first conical surface and a second conical surface, and a second plunger arm (788b') having a first conical surface and a second conical surface. The distal end includes a first contact surface defined by the first conical surface of the first plunger arm and the first conical surface of the second plunger arm, the first contact surface configured to initially contact a firing engagement mechanism, the first contact surface disposed at a first angle of between about 400 and about 800 relative to a longitudinal axis of the syringe plunger.
