Abstract: A drug delivery device includes a housing having proximal and distal ends and a longitudinal axis extending therebetween, an injection assembly at least partially disposed within the housing at or near the proximal end, a shield slidably coupled with the housing, a drive assembly operably coupled with the injection assembly and the shield, and a cap. The injection assembly includes a needle or a cannula. The shield is positionable in an extended position in which at least a proximal end thereof extends a distance beyond the proximal end of the housing. The drive assembly is engageable to deliver a medicament via the injection assembly. The cap is removably coupled with at least one of the shield or the housing and is adapted to limit movement of the shield when coupled with the shield and/or the housing such that the drive assembly is restricted from delivering the medicament via the injection assembly.

Abstract: A drug delivery device includes a housing having proximal and distal ends and a longitudinal axis extending therebetween, an injection assembly at least partially disposed within the housing including a needle or a cannula, a drive assembly operably coupled with the injection assembly, a shield slidably coupled with the housing and operably coupled with the drive assembly, and a retention mechanism. The drive assembly is engageable to deliver a medicament via the injection assembly. The shield is positionable in an extended position in which at least a proximal end extends a distance beyond the proximal end of the housing and a retracted position where the proximal end of the housing protrudes a distance beyond the proximal end of the shield. Moving the shield to the retracted position engages the drive assembly to deliver the medicament via the injection assembly. The retention mechanism limits movement of the drive assembly to restrict engagement thereof such that the drive assembly is restricted from delivering the medicament via the injection assembly.

Abstract: A drug delivery device including a housing, a drug storage container, and a removable cap is provided. The removable cap may be configured to be removably coupled with the housing such that the removable cap has a storage position where the removable cap is coupled with the housing and at least partially covering an opening in the housing and a removed position where the removable cap is not coupled with the housing. The removable cap may include an outer portion, an inner portion, and a gap separating at least a portion of the inner portion and at least a portion of the outer portion such that the at least a portion of the outer portion is allowed to bend with respect to the at least a portion of the inner portion if the at least a portion of the outer portion is subjected to an external force. Additionally or alternatively, the removable cap may be configured such that an external force applied to the removable cap induces at least one bending moment in a proximal end and/or a distal end of the removable cap.
