SUB-ASSEMBLIES FOR MEDICAMENT DELIVERY DEVICES AND CORRESPONDING METHODS OF ASSEMBLY

Abstract: the present disclosure provides a sub-assembly for a medicament delivery device, the sub-assembly comprising a housing and a rear cap arranged coaxially in the housing. the housing is tubular and extends from a proximal end to a distal end along a longitudinal axis in an axial direction, and the housing includes an inner surface and an outer surface. the inner surface of the housing includes a first surface facing in the distal direction and a second surface facing in the distal direction. the second surface is closer to the distal end of the housing than the first surface. the rear cap extends from a proximal end to a distal end along the longitudinal axis. the rear cap includes a flexible arm, the flexible arm comprising a first surface facing in the proximal direction, and the rear cap comprises a second surface facing in the proximal direction.
