Abstract: Syringe carriers for medicament delivery devices are described where a medicament delivery device sub-assembly extending along a longitudinal axis from a proximal end to a distal end is described having a tubular housing, a tubular syringe carrier inside the housing and a syringe inside the syringe carrier. The syringe includes a needle shield and a medicament container comprising a shoulder. The housing includes a flexible arm extending in the axial direction relative to the longitudinal axis, the flexible arm having an inwardly extending protrusion arranged in a gap between the shoulder and the needle shield. The syringe carrier has a proximal portion and a distal portion, and the proximal portion is arranged adjacent to the flexible arm of the housing so that movement of the flexible arm of the housing in a radial direction relative to the longitudinal axis is restricted by the proximal portion of the syringe carrier.

Abstract: The present disclosure provides a medicament container carrier of a medicament delivery device, the medicament container carrier including a tubular body for receiving a medicament container, the tubular body extending along a longitudinal axis between a proximal open end and a distal open end, the tubular body including a fastener. The medicament container further includes a proximal cap with a tubular cap body. The tubular cap body extends along the longitudinal axis between a proximal end and a distal end. A slot extends on the tubular cap body from the proximal end to the distal end. The tubular cap body includes a ledge extending from an inner surface of the tubular cap body. The ledge is radial relative to the longitudinal axis, and the ledge is configured to support a shoulder part of the medicament container of the medicament delivery device. The proximal cap includes a counter fastener offset relative to the ledge in the direction of the longitudinal axis. The proximal cap is attached to the proximal end of the tubular body through an engagement between the fastener and the counter fastener.
