Abstract: A fluid product dispenser comprising a tank and a metering device mounted on the tank, the metering device having a chamber defining an inlet, an abutment, an outlet and a sealing seat, the abutment separated from the sealing seat by a stroke distance; a valve movable inside the chamber over the stroke defined between a rest position, in which the valve is biased by a return force towards the abutment, and an end position, in which the valve is selectively urged onto the sealing seat against the return force by the fluid flowing in the chamber from the inlet to the outlet; and a mechanism for adjusting the stroke of the valve capable of adjusting the stroke distance separating the abutment from the sealing seat. The adjustment mechanism is located in the fluid tank, so that they are inaccessible and cannot be actuated from outside the fluid product dispenser.

Abstract: Fluid product dispenser (D) having a reservoir (R) defining a bottom (R1) and an opening (R2), and a dispensing head (T) integrating a dispensing member (P) defining a vent path through which outside air can penetrate into the reservoir (R). The dispensing member (P) has a dip tube (TP) that extends into the reservoir (R), the dip tube (TP) having an inlet (Ti) close to the bottom (R1) of the reservoir (R). The inlet (Ti) of the dip tube (TP) is provided with a shut-off valve (V) having a movable member (V6) and a seat (V5), the movable member (V6) is urged into sealed contact with the seat (V5) by the fluid product when the dispenser (D) is upside down, while the movable member (V6) is urged away from the seat (V5) by the fluid product when the dispenser (D) is upright.

Abstract: A reservoir for a fluid product having a container defining a neck and a mounting part mounted on the neck, the mounting part forming a basket arranged at the neck and a plunger tube, which extends from the basket into the container, the plunger tube being initially sealed by a sealing member. The reservoir further has an insert located in the basket and having a piercing element capable of moving between an initial position, in which the sealing member forms a seal, and a final position, in which the sealing member is displaced by the piercing element to an open state.

Abstract: Lipstick refill having a cup, a stick of lipstick received in the cup so as to jointly form a refill entity, and a case in which the refill entity is fixedly and removably received, the case forming a longitudinal indentation. The cup is provided with a push-button radially projecting on the outside of the case and passing through said longitudinal indentation.
