Fluid product dispenser comprising an actuating part for a storage subassembly

A fluid product dispenser comprising:

• a dispensing head for dispensing the fluid product,
• a container for the fluid product,
• a dispensing pump attached to the dispensing head by an upper part of the dispensing pump,
• an actuating part attached to said container and capable of being displaced according to an axial displacement from a rest position towards a product dispensing position, and
• a cam ring movable in rotation relative to the actuating part,
• the actuating part comprising first cam means cooperating with second cam means of the cam ring so that the axial displacement is obtained by a transformation of a rotational movement of the actuating part with respect to the cam ring, the axial displacement allowing an actuation of the dispensing pump,
• the cam ring further comprising at least one first locking means cooperating with at least one second locking means of the dispenser so as to block the rotational movement of the actuating part with respect to the cam ring when the actuating part is in a low rest position.
