1. An activation mechanism for a medicament delivery device comprising:
a housing having a proximal end terminating in a proximally directed surface; and
a guard axially moveable relative to the housing and comprising:
a blocking element having a blocking position and a release position; and
a radial extending flange configured to engage a dose delivery site,
wherein when the guard is in an initial position, the blocking element is not in contact with the proximally directed surface of the housing,
wherein when the flange is pressed against the dose delivery site, the blocking element, when in the release position, will move distally and axially past the proximally directed surface of the housing, and
wherein when the blocking element is in the blocking position, the guard is free to move distally and axially relative to the housing until the blocking element engages the proximally directed surface of the housing such that the engagement of the blocking element with the proximally directed surface of the housing will prevent further axial movement of the guard in the distal direction.
