Fluid dispenser device
A fluid dispenser device having a fluid dispenser member, the fluid dispenser member fastened by a fastener ring ( 30 ) on a reservoir ( 1 ). An actuator head ( 20 ) is mounted on the dispenser member and is movable so as to actuate the dispenser member. A removable blocking element ( 40 ), in its blocking position, prevents the dispenser member from being actuated. At least one breakable element ( 50 ) is secured to the blocking element so as to indicate first use. The blocking element is assembled around the fastener ring ( 30 ), between the head ( 20 ) and the reservoir ( 1 ), and, in its blocking position, co-operates with the actuator head and the reservoir so as to prevent the actuator head from moving axially relative to the reservoir. The breakable element ( 50 ) surrounds the blocking element ( 40 ), at least in part, before first use.
1. 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.
2. A device according to claim 1 , wherein said breakable element is clipped on said blocking element while being assembled.
3. A device according to claim 2 , wherein said blocking element includes at least one opening that is adapted to receive at least one clip element for clipping said breakable element.
4. A device according to claim 1 , wherein the blocking element includes at least one projection that extends radially towards the inside of said blocking element.
5. A device according to claim 1 , wherein the blocking element comprises an open ring that is elastically deformable.
6. A device according to claim 5 , wherein the blocking element and said at least one breakable element form a closed ring before first use.
7. A device according to claim 1 , wherein said at least one breakable element is adapted to break when separated from the blocking element.
8. A device according to claim 5 , wherein said at least one breakable element is formed by a strip that interconnects the two sides of said open ring before first use.
9. A device according to claim 8 , wherein, before first use, said strip:
at a first end, has a solid connection to a first of said two sides of said open ring;
extends around the portion of the side wall of said fastener ring that is not encircled by said open ring; and
at a second end, co-operates with the second of said two sides of said open ring.
10. A device according to claim 8 , wherein said strip breaks at a solid connection between said strip and said open ring.
11. A device according to claim 1 , wherein the blocking element is held in its blocking position by retaining means, said retaining means being elastically deformable.
12. A device according to claim 11 , wherein said retaining means are formed by an open ring and/or by at least one projection.
13. A device according to claim 5 , wherein said blocking element includes grip means for snap-fastening and unfastening said open ring.
14. The device according to claim 1 , wherein said fluid dispenser is a manually actuated pump or valve.
15. A fluid dispenser device comprising:
a fluid dispenser member fastened by a fastener ring on a reservoir;
an actuator head mounted on the dispenser member and movable so as to actuate the dispenser member;
a blocking element that is removable and when, in a blocking position, prevents the dispenser member from being actuated; and
a breakable element secured to the blocking element so as to indicate first use;
the blocking element assembled around the fastener ring between the head and the reservoir, and, in the blocking position, co-operates with the actuator head and the reservoir to prevent the actuator head from moving relative to the reservoir, the breakable element surrounding the blocking element, at least in part, before first use; and
the 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 co-operate with the actuator head and the reservoir so as to prevent the actuator head from moving axially relative to the reservoir;
wherein the blocking element is detached and reattached by movement transverse relative to a longitudinal axis of the dispenser member, the actuator head moving along the longitudinal axis of the dispenser member to actuate the dispenser member.
