Injection Device

An injection device, comprising:

• a housing having a distal end and a proximal end and an abutment surface provided near the proximal end of the housing, the abutment surface extending at least partially around a perimeter of the housing and facing away from the distal end and at least one engagement structure provided at the abutment surface;
• a cap removably attached to the proximal end of the housing and having a proximal end and a distal end with an opening at the distal end, wherein internal dimensions of the opening correspond to outer dimensions of the proximal end of the housing, thereby allowing the cap to slip onto the proximal end of the housing;
• and
• a first lifting pole pivotally arranged within the cap, the first lifting pole being pivotally connected to the cap at a proximal end of the first lifting pole by a pivotal connection and being arranged to bear against the abutment surface at a distal end of the first lifting pole when the cap is in a fully attached position on the housing;
• wherein the first lifting pole extends from the abutment surface to the pivotal connection to the cap along an axis inclined relative to a longitudinal axis of the housing when the cap is in the fully attached position;
• wherein relative rotational movement between the cap and the housing in a first direction around the longitudinal axis causes the distal end of the first lifting pole to engage with the at least one engagement structure and alignment of the first lifting pole with the longitudinal axis of the housing, thereby causing axial displacement of the cap relative to the housing toward a detached position of the cap.
