Description

TITLE A cap assembly of a medicament delivery device TECHNICAL FIELD The present disclosure generally relates to a cap assembly of a medicament delivery device, and particularly to a cap assembly of a medicament delivery device that comprises a delivery member shield remover. BACKGROUND Medicament delivery devices such as pen-type manual injectors or auto-injectors are generally known for the self-administration of a medicament by patients without formal medical training. For example, patients suffering from diabetes may require repeated injections of insulin, or patients may require regular injections of other types of medicaments, such as growth hormones. It is an advantage when the medicament delivery devices for self-administration comprise automatic functions so that even if users are without professional training or are in an emergency situation, the users can easily and properly use the medicament delivery devices. Even though many of the devices on the market, as well as the ones described above, have their respective advantages, there is still room for improvement. SUMMARY The invention is defined by the appended claims, to which reference should now be made. In the present disclosure, when the term “distal direction” is used, this refers to the direction pointing away from the dose delivery site during use of the medicament delivery device. When the term “distal part/end” is used, this refers to the part/end of the delivery device, or the parts/ends of the members thereof, which under use of the medicament delivery device is/are located furthest away from the dose delivery site. Correspondingly, when the term “proximal direction” is used, this refers to the direction pointing towards the dose delivery site during use of the medicament delivery device. When the term “proximal part/end” is used, this refers to the part/end of the delivery device, or the parts/ends of the members thereof, which under use of the medicament delivery device is/are located closest to the dose delivery site. Further, the term “longitudinal”, “longitudinally”, “axially” or “axial” refer to a direction extending from the proximal end to the distal end, typically along the device or components thereof in the direction of the longest extension of the device and/or component. Similarly, the terms “transverse”, “transversal” and “transversally” refer to a direction generally perpendicular to the longitudinal direction. Further, the terms “circumference”, “circumferential”, or “circumferentially” refer to a circumference or a circumferential direction relative to an axis, typically a central axis extending in the direction of the longest extension of the device and/or component. Similarly, “radial” or “radially” refer to a direction extending radially relative to the axis, and “rotation”, “rotational” and “rotationally” refer to rotation relative to the axis. There is hence provided a cap assembly of a medicament delivery device. The cap assembly comprising: a cap body extending along a longitudinal axis between a proximal end and a distal end; and a delivery member shield remover extending along the longitudinal axis between a proximal end and a distal end. The delivery member shield remover is positioned within the cap body. The delivery member shield remover comprises a grabber configured to be engaged with a delivery member shield of the medicament delivery device such that a user of the medicament delivery device can remove the delivery member shield when remove the cap assembly from a housing of the medicament delivery device. The cap body comprises a proximally directed surface adjacent to a distally directed surface of the delivery member shield remover. The cap body comprises a user-accessible surface configured to be gripped by the user of the medicament delivery device such that the user can remove the cap assembly from the housing of the medicament delivery device via gripping on the user-accessible surface. The distally directed surface of the delivery member shield remover is positioned closer to the distal end of the delivery member shield remover than the proximal end of the delivery member shield remover. Preferably, according to one embodiment, the proximally directed surface and the user-accessible surface are immovable relative to one another. For example, the proximally directed surface and the user- accessible surface are two parts of one single component such that the proximally directed surface and the user-accessible surface are neither axially movable nor rotatable relative to one another. Thus, the force from the user can be transferred to the delivery member shield remover efficiently. Preferably, according to one embodiment, the distal end of the delivery member shield remover comprises the distally directed surface of the delivery member shield remover. Preferably, according to one embodiment, the grabber of the delivery member shield remover comprises a proximally directed surface configured to b
