Patent ID: 8075534

Claim:
An injection device, comprising: a) a dose metering element, b) a mechanism holder coupled to the dose metering element, relative to which the dose metering element can be rotated to set a dose, c) a lock element on one of the mechanism holder and dose metering element, the lock element resiliently arranged in the radial direction, d) a lock complementary element on the other of the mechanism holder and dose metering element in which the lock element can resiliently engage as the dose metering element rotates, and e) a blocking element for establishing a locking engagement between the lock element and the lock complementary element, which blocks the rotation of the dose metering element relative to the mechanism holder, f) wherein, as the set dose is primed by a translational movement of a drive element along a longitudinal direction of the injection device, the blocking element is slaved by the drive element and establishes the locking engagement.
