  • Patent number: 10175128
    Abstract: The invention deals with a measuring apparatus (1) comprising a body (11) with an interior (114) and an opening for accessing the interior (114) from outside the body (11), a rigid plunger (12) having an edge (1212) being identically shaped as an edge of a opening of a target vial, and a force sensor (13). The rigid plunger (12) extends though the opening of the body (11) into the interior (114) of the body (11). The edge (1212) of the rigid plunger (12) is arranged outside the body (11). The force sensor (13) is arranged in the interior (114) of the body (11). The rigid plunger (12) is movable relative to the body (11) and is coupled to the force sensor (13). The apparatus (1) can be used for measuring a force acting on the edge of the opening of the target vial for optimizing the adjustment of a vial closure facility.
