Abstract: The present disclosure generally relates to medicament delivery devices such as autoinjectors, and particularly concerns a subassembly for removing a needle shield.

Abstract: The present disclosure provides a medicament delivery device configured to expel a medicament from a medicament container comprising an injection needle. The medicament delivery device is configured to assume a retracted state in which an injection needle is arranged inside a medicament delivery member and prevented from external exposure, and a protracted state in which the injection needle is configured to protrude proximally from the proximal end of the medicament delivery member. When the medicament delivery device transition from the retracted state to the protracted state, the medicament delivery member is arranged stationary relative to a housing. The syringe collar is axially locked to a surface portion of the housing when the medicament delivery device assumes the protracted state such that an axial force from the syringe collar, generated during the transition from the retracted state to the protracted state, is absorbed by the surface portion of the housing.
