Abstract
A resettable dosing mechanism comprises a dose button and a dial grip operatively coupled to the dose button. A spindle acts on a bung of a cartridge and a driver is operatively coupled between the dose button and the spindle. During an injection of the dose, the dose button moves in an axial direction to cause the spindle to administer the dose. During resetting of the dose setting mechanism, the spindle is retracted back into the dose setting mechanism. An advantageous resetting mechanism is described.
