Abstract

A dose setting mechanism is provided that includes a dose knob, a dose selector, a radial projecting rib and a snap element. The radial projecting rib is positioned circumferentially on an inside surface of the dose selector. The snap element includes a protrusion. The protruding rib has a reduced section that allows the protruding rib to move axially relative to the protrusion to initiate dose delivery.
