First Claim
1. A medicament delivery device comprising an activating mechanism, the activating mechanism comprising:
- a hollow injection needle;
a cartridge containing a dosage of a medicament;
a cartridge carrier comprising at least one resilient arm configured to hold the cartridge;
a removable needle cap configured to cover the injection needle; and
a drive element adapted to couple with the cartridge;
wherein the cartridge is retained in a position spaced apart from the injection needle in a proximal direction by the at least one resilient arm when the medicament delivery device is in an initial position,wherein by removing the needle cap, the cartridge is releasable and configured to be pushed into a distal direction by the drive element with respect to the cartridge carrier,wherein an inner surface of a proximal end of the removable needle cap is configured to bear against an outer surface of the at least one resilient arm, andwherein an outer surface of the proximal end of the removable needle cap is configured to bear against an inner surface of the cartridge carrier.
