A fluid product dispenser includes: a fluid product tank, a dispenser part
comprising a pierced membrane connected directly to the tank, a mechanism
to vibrate the pierced membrane, and an actuator button to activate the
vibration mechanism. The tank is located above the pierced membrane such
that the fluid product is supplied to the membrane from the tank using the
force of gravity under normal operating conditions. The membrane is
connected to the tank by a passage provided with an inlet valve capable of
opening and cutting off the passage selectively.
