  • Plunger sub-assembly for a prefilled medicament injector, a prefilled medicament injector and method for assembling a prefilled medical injector
    Patent number: 11628256
    Abstract: A plunger sub-assembly (40, 60, 70; 80) for a pre-filled medicament injector for expelling a dose of a medicament, comprising: a) a container (60) holding a medicament, the container (60) comprising a body (61) with a proximally facing rim surface (64), and a distally slideable piston (63); b) a plunger (40); and c) a tolerance compensating element (70; 80) configured to cooperate with the plunger (40) and to cooperate with either the proximally facing rim surface (64) or the piston (63), the tolerance compensating element (70; 80) being rotatable relative to the plunger (40) to adjust the piston (63) end of dose position. The plunger sub-assembly (40, 60, 70; 80) is formed so that end of dose state occurs by the plunger (40) cooperating with the proximally facing rim surface (64). Pre-filled medicament injectors and methods of assembling a pre-filled medicament injector are further described.

The plunger sub-assembly (40, 60, 70; 8) is formed so that end of dose state occurs by the plunger (40) cooperating with the proximally facing rim surface (64). Pre-filled medicament injectors and methods of assembling a pre-filled medicament injector are further described.
