a fluid product filling valve at the bottom portion of the fluid product reservoir above the filling port, the fluid product filling valve comprising a fixed insert and a moveable member that is axial movable relative to the fixed insert between a closed position in which the moveable member is seated on the fixed insert providing a fluid tight seal and an open position in which the moveable member is unseated from the fixed insert providing a passage for fluid through the fluid product filling valve,
a fluid product chamber between the filling port and the filling valve,
the fluid product chamber comprising an anti-drip retention device for retaining the fluid product inside the fluid product chamber downstream of the filling port, the anti-drip retention device configured to prevent fluid product from leaking out of the fluid product chamber from the filling port and comprising one of:
an anti-drip valve that is normally closed and that opens during filling,
a flexible bottom wall that deforms inwardly to reduce a volume of the fluid product chamber during filling and deforms outwardly to increase the volume of the fluid product chamber after filling, or
