17. A method of removing an inner injection needle cap from an injection needle in a medicament delivery device, the method comprising:
moving a cap assembly of the medicament delivery device a predetermined distance in a proximal direction to remove the cap assembly and the inner injection needle cap from the medicament delivery device, wherein an outer injection needle cap is located over the inner injection needle cap, the outer injection needle cap comprising a proximal section and a distal section, wherein the proximal section is relatively closer to a site of injection than the distal section, and wherein the cap assembly comprises a stop member configured to engage a distal section of the outer injection needle cap at a location distal of a proximal end of the injection needle to remove the outer injection needle cap from the inner injection needle cap prior to the removal of the inner injection needle cap from an injection needle holder when the cap assembly is moved in the proximal direction.
