Abstract
An auto-injector for dispensing a predetermined dose of medicament is disclosed. The auto-injector includes a needle cover operative to engage an injection site. The needle cover is configured to move from a retracted position prior to a medicament dispensing operation to an extended locked position after the medicament dispensing operation. Any residual activation force remaining after the medicament dispensing operation is contained within the auto-injector and is not directed to the needle cover, thus attenuating, if not eliminating, any kickback effect.
