The present disclosure relates to a medicament delivery device comprising a housing having a proximal end and contains a container of medicament positioned within the housing in a medicament container holder. The medicament container can be dual chambered, for example a pre-filled medicament container having a needle, a dose of medicament and one or more sliding stoppers. The medicament container holder can be configured with a recess or pocket to accommodate the loading of a dual chambered container and interact with an inside surface of the housing to rotationally fix the container holder relative to the housing and the medicament container. A tubular activation member, e.g., a needle cover, is slidably positioned within a housing of the delivery device to move from a first position to a second position, and then to a final locked position. A plunger rod can only move proximally relative to the needle cover when the needle cover is in the second position.

A medicament delivery device having a power pack that includes a rotator having an outer surface that is arranged with guide ledges, at least some of the guide ledges being longitudinal guide ledges extending axially in the longitudinal direction and at least some of the guide ledges being inclined guide ledges inclined relative to the longitudinal direction, the guide ledges defining one or more guide tracks that accept and provide a pathway for one or more protrusions located on a distal end of a delivery member guard and wherein axial travel of the delivery member guard and the one or more protrusions within the guide tracks in a distal direction results in activation of the medicament delivery device.
A transport lock assembly for a powerpack of a medicament delivery device, which transport lock is unlocked at the time of final assembly and comprises a plunger rod, an actuator for holding the plunger rod in a pre-tensioned state, a rotator for releasing the plunger rod, and a locking member configured to interact with the rotator, which locking member is movable, relative to the rotator, from a first state in which the rotator is immobilized, to a second state in which the rotator is free to move, the transport lock assembly being further characterized by a housing having a key member, which housing is configured to receive the powerpack, and wherein assembly of the powerpack with the housing causes the key member to move the locking member from the first state to the second state relative to the rotator.
A rotator for a medicament delivery device, the rotator comprising:
