A holding fixture for a fill container comprising a vial, which vial is comprising a medicament contained therein, the vial having a first longitudinal axis and a neck at a proximal end of the thereof, the neck proximally terminating at a circumferential lip, the lip defining an opening, the final fill container further comprising a stopper positioned at least partially within the vial opening and forming an air-tight seal with the vial, and a cylindrical shell including a button aligned with the first longitudinal axis and circumscribing the lip and the stopper, the holding fixture comprising: a pair of rigid support structures (20, 20a, 20b), each rigid support structure (20, 20a, 20b) comprising: a first inner support having a first inner surface with a first radius of curvature about a first inner support longitudinal axis, the first inner surface facing radially inward; and a first support arm (22, 22a) connected to the first inner support and extending in an outward direction away from the first inner surface, the first support arm (22, 22a) having a base surface at a terminal end opposite from the first inner support, the holding fixture further comprising: a first compression member attached to the first inner surface, the first compression member being configured to contact a shell of a vial when the first inner support longitudinal axis is colinear with a longitudinal axis of the vial, characterized in that the pair of rigid support structures (20, 20a, 20b) has a closed orientation when the first compression member from one of the pair of rigid support structures (20, 20a, 20b) contacts the first compression member from the other one of the pair of rigid support structures (20, 20a, 20b) forming a first annular compression member. which vial is comprising a medicament contained therein, the vial having a first longitudinal axis and a neck at a proximal end of the thereof, the neck proximally terminating at a circumferential lip, the lip defining an opening, the final fill container further comprising a stopper positioned at least partially within the vial opening and forming an air-tight seal with the vial, and a cylindrical shell including a button aligned with the first longitudinal axis and circumscribing the lip and the stopper, the holding fixture comprising: a pair of rigid support structures (20, 20a, 20b), each rigid support structure (20, 20a, 20b) comprising: a first inner support having a first inner surface with a first radius of curvature about a first inner support longitudinal axis, the first inner surface facing radially inward; and a first support arm (22, 22a) connected to the first inner support and extending in an outward direction away from the first inner surface, the first support arm (22, 22a) having a base surface at a terminal end opposite from the first inner support, the holding fixture further comprising: a first compression member attached to the first inner surface, the first compression member being configured to contact a shell of a vial when the first inner support longitudinal axis is colinear with a longitudinal axis of the vial, a first inner support having a first inner surface with a first radius of curvature about a first inner support longitudinal axis, the first inner surface facing radially inward; and a first support arm (22, 22a) connected to the first inner support and extending in an outward direction away from the first inner surface, the first support arm (22, 22a) having a base surface at a terminal end opposite from the first inner support, the holding fixture further comprising: a first compression member attached to the first inner surface, the first compression member being configured to contact a shell of a vial when the first inner support longitudinal axis is colinear with a longitudinal axis of the vial, characterized in that the pair of rigid support structures (20, 20a, 20b) has a closed orientation when the first compression member from one of the pair of rigid support structures (20, 20a, 20b) contacts the first compression member from the other one of the pair of rigid support structures (20, 20a, 20b) forming a first annular compression member.
