A shutter member for a fluid dispenser member, the shutter member having a substantially rigid base body and an elastically deformable diaphragm, the body and the diaphragm being made of materials that are chemically compatible such that the material of the diaphragm adheres to the material of the body, the body defining an anchor zone and a fluid-passing zone. The diaphragm adheres to the anchor zone and extends over the fluid-passing zone, the fluid-passing zone including an interface that is secured to the fluid-passing zone but that does not adhere to the diaphragm, thereby defining an outlet channel for fluid between the interface and the diaphragm in the presence of fluid under pressure.

Stopper valve and method for making such valve

A fluid dispenser comprising: a fluid reservoir () of variable working volume, in which reservoir the fluid is protected from the air, the reservoir being provided with an actuator wall () that is axially movable down and up between a rest position and a depressed position, the movement of the wall causing the pressure in the reservoir to vary, the wall being situated at an end of the dispenser; and a dispenser orifice () via which the fluid is dispensed, the orifice being provided with an outlet valve (); the dispenser being characterized in that the orifice () is situated at an end of the dispenser other than the end at which the actuator wall () is situated.

Fluid dispenser

A fluid dispenser member () for associating with a fluid reservoir () so as to form a fluid dispenser, the member () including a body () via which the dispenser member is mounted in stationary manner on a mounting part (), the body () defining a housing () for receiving another component element () of the dispenser member. The housing () includes a movable portion () that is displaceable from an initial configuration in which the housing is open, to a final configuration in which the housing is closed on the component element () while the dispenser member () is being mounted in the mounting part ().

Fluid product dispensing member and dispenser comprising same

A dispenser head () for associating with a dispenser member, such as a pump or a valve, so as to form a fluid dispenser, the head including a connection sleeve () for connecting to an outlet () of the dispenser member, the sleeve () being connected to a fluid dispenser orifice () via an internal channel (), the head being characterized in that it further includes a fluid collection dish () for collecting the fluid at the outlet from the dispenser orifice, the dish defining a bottom () that is situated below the dispenser orifice under normal conditions of use of the head, such that the fluid drops by gravity into the dish.

Dispensing nozzle for a dispenser of fluid product

A fluid dispenser device comprising: a reservoir (R) of variable working volume comprising a sealing slide-cylinder () and a follower piston () that is in sliding sealing contact in said cylinder; dispenser means () that are suitable for putting the fluid stored in the reservoir under pressure in such a manner as to drive a fraction of the fluid through a dispenser orifice (), and under suction in such a manner as to move the follower piston in the direction that decreases the working volume of the reservoir; and non-return means that are suitable for preventing any substantial movement of the follower piston in the direction that increases the working volume of the reservoir; in which device the non-return means include at least one chamber (C) of variable volume that is filled with fluid from the reservoir during the suction stage.
