The present disclosure relates to a cap assembly for a medicament delivery device, having a cap containing a tubular body provided with a distal opening, the cap being configured to be mounted to a proximal end of a medicament delivery device, a tubular remover configured to be received in the distal opening of the cap, the remover having flexible radially inwards extending grippers configured to engage with a delivery member shield, and a tubular remover insert configured to be received by the remover and configured to be fixedly attached to the cap to prevent axial displacement of the remover insert relative to the cap, wherein the remover is axially displaceable relative to the cap and relative to the remover insert, from a first position in which the grippers are pressed radially outwards by an outer surface of the remover insert, to a second position located distally relative to the first position, in which second position the grippers are arranged distally beyond the outer surface of the remover insert, enabling the grippers to flex radially inwards to allow engagement with a delivery member shield.

Sub-assembly for a medicament delivery device

A power pack assembly for a medicament delivery device, the power pack comprising a plunger rod () extending along a longitudinal axis (L) and having a proximal and an opposite distal ends, an actuator () provided with a holding element () and configured to interact with a corresponding holding element on the plunger rod (), a first force element () arranged to exert a force on the plunger rod; an actuator sleeve mechanism () arranged to releasably lock said holding element () in engagement with the corresponding holding element of said plunger rod () such as to hold said first force element () in a tensioned state. The invention is characterized in that said actuator sleeve mechanism () comprises an actuator cap () configured to hold said holding element () in engagement with the corresponding holding element of said plunger rod () and an actuator sleeve () interconnected with said actuator cap () such that in relation to the actuator (), said actuator cap () is moved a shorter distance than the actuator sleeve () when said actuator sleeve is distally displaced in relation to the distal housing part.
