Abstract: A safety arrangement for being used in a medicament delivery device, comprising a container holder with a body section and a flange seat and a shell. The container holder is arranged to receive a container with a longitudinal body at one end passing over into a distal flange and at an opposite end passing over into a proximal orifice via a shoulder, such that the distal flanges of the container contacts the flange seat of the container holder. Moreover, the container holder is arranged in the shell such that the container holder is movable in a proximal direction in relation to the shell. A blocking element is arranged between the shell and the container holder. A blocking initiating structure is arranged to reposition the blocking element when the container holder is moved in the proximal direction in relation to the shell from a first position to a second position.

Abstract: The present invention relates to a safety arrangement for being used in a medicament delivery device (1), comprising a container holder (2) with a body section (21) and a flange seat (22), and a shell (3). The container holder (2) is arranged to receive a container (4) with a longitudinal body (41) at one end passing over into a distal flange (42) and at an opposite end passing over into a proximal orifice (43) via a shoulder (44), such that the distal flange (42) of the container (4) contacts the flange seat (22) of the container holder (2). Moreover, the container holder (2) is arranged in the shell (3) such that the container holder (2) is movable in a proximal direction in relation to the shell (3). A blocking element (5) is arranged between the shell (3) and the container holder (2).
