Patent ID: 8336739

Claim:
A fluid dispenser device comprising: a fluid dispenser member, said fluid dispenser member being fastened by a fastener ring on a reservoir; an actuator head that is mounted on said dispenser member, and that is movable so as to actuate said dispenser member; a removable blocking element that, in a blocking position, prevents the dispenser member from being actuated; and at least one breakable element that is secured to the blocking element so as to indicate first use; said blocking element is assembled around the fastener ring, between the head and the reservoir, and, in the blocking position, cooperates with said actuator head and said reservoir so as to prevent said actuator head from moving axially relative to said reservoir, said at least one breakable element surrounding said blocking element, at least in part, before first use; and said blocking element is structured to be detached and reattached to the dispenser device so as to be reusable without loss of the blocking element's ability to cooperate with the actuator head and the reservoir so as to prevent the actuator head from moving axially relative to the reservoir; and wherein the blocking element is detached and reattached by movement transverse relative to a longitudinal axis of the dispenser member.
