Abstract: A fluid dispenser member, including a chamber and an outlet valve having an actuator rod that is axially movable down and up, and on which a sleeve slides, under the effect of a pre-compression spring and the pressure of the fluid, over a maximum axial stroke. The effective axial stroke of the sleeve is dependent on the force of the spring and the pressure of the fluid in the chamber. The actuator rod includes side outlet mechanism that is suitable for being closed and uncovered selectively by the sleeve, the side outlet mechanism extending over an axial height that is greater than their radial width.

Abstract: A fastener device for fastening a dispenser member on a neck of a reservoir, the device including a fastener ring. The fastener ring having reception mechanism for receiving, in stationary manner, the dispenser member; an annular plate for exerting axial pressure on the neck; and a fastener skirt that extends downwards from the plate, the skirt including a fastener mechanism for fastening around the neck. The ring is made of two different plastics materials, a substantially-hard first material and a flexible second material that is more flexible than the first material. The device also includes a hoop that, in the final assembled position, extends around the skirt of the ring with radial clamping. The flexible second material comes into contact with the hoop.

Abstract: A fluid dispenser including a reservoir forming a neck presenting a thread, a dispenser member, and a fastener system including a fastener ring provided with assembly means for assembling on the thread of the neck in such a manner that the ring is unscrewable from the neck over an axial unscrewing stroke. The outer wall of the neck is provided with a shoulder, and the fastener system includes a security band engaged on the fastener ring. The band axially abuts the shoulder and is secured to the fastener ring at the end of the unscrewing stroke, so as to prevent the fastener system from being removed from the neck immediately after the fastener ring has been unscrewed. The security band includes an unblocking mechanism for disengaging the band from its axial abutment with the shoulder of the neck.
