    • A mix and triggering assembly (20) for a medicament delivery device (1), comprising: a housing structure (3) having a proximal end (3a) and a distal end (3b), a delivery member cover (5), a rotator sleeve (11), and a triggering member (13) configured to be rotatably locked with the rotator sleeve (11) and the delivery member cover (5), the triggering member (13) being configured to move axially relative to the rotator sleeve (11), wherein the delivery member cover (5), the rotator sleeve (11) and the triggering member (13) are configured to be received by the housing structure (3), the delivery member cover (5) being configured to extend from the proximal end (3a) of the housing structure (3), wherein the delivery member cover (5), the rotator sleeve (11) and the triggering member (13) are rotatably arranged relative to the housing structure (3), wherein the housing structure (3) has a thread structure and the rotator sleeve (11) and the triggering member (13) are configured to be in a threaded connection with the thread structure in a ready to mix position of the triggering member (13), preventing irrotational axial movement of the triggering member (13) relative to the housing structure (3) towards the distal end (3b) of the housing structure (3), wherein rotation of the delivery member cover (5) relative to the housing structure (3) causes the rotator sleeve (11) and the triggering member (13) to be screwed from the ready to mix position towards the distal end (3b) of the housing structure (3) until the triggering member (13) reaches a dose setting position, in which the triggering member (13) is configured to be released from engagement with the thread structure (3c), enabling irrotational axial movement of the triggering member (13) further towards the distal end (3b) of the housing structure (3).

    • The present invention relates to an actuation mechanism (40) to be used with a medicament delivery device, the actuation mechanism comprising: a plunger rod (42) arranged to act on a stopper (18) of a medicament container (16); an actuator (84) arranged slidable and connected to the plunger rod (42) for acting on the stopper (18) when said actuator (84) is operated by displacing it in a longitudinal direction of the actuation mechanism (40); an activator (104) rotatably arranged for activating said actuation mechanism and for setting a dose; said activator (104) comprising a generally tubular activator sleeve (148) provided with a spirally extending groove (152) on its outer surface, said groove (152) arranged with a length corresponding to the total amount of medicament to be delivered in a number of doses contained in said medicament container (16), said groove (152) provided with an end wall (154), a stop ring (158) arranged coaxial with said activator sleeve (148); said activator sleeve (148) arranged with a follower (156) positioned in said groove (152), wherein said follower (156) is arranged to abut said end wall (154) of said groove (152) when said total amount has been delivered.
