Fluid product dispensing member and a dispenser provided therewith

1. A fluid dispenser member for associating with a fluid reservoir ( 3 ), said member comprising:

a body ( 1 );

a fastener ring ( 2 ) for holding the body in stationary manner relative to the reservoir ( 3 );

a covering hoop ( 6 ) that is engaged in stationary manner around the fastener ring ( 2 );

an actuator rod ( 15 ) that is axially movable down and up in the body ( 1 ); and

a pusher ( 4 ) that is mounted on the actuator rod ( 15 ), the pusher being provided with a dispenser orifice ( 44 ); and

blocking means ( 49 , 5 , 62 ) secured to the hoop so as to prevent the pusher from turning on the actuator rod relative to the body, and consequently relative to the reservoir, such that the pusher is movable only axially, the blocking means comprising at least one longitudinal axial guide ( 55 ) and a guide bushing that is received in stationary manner in the hoop and that is engaged around the pusher, the bushing forming the at least one longitudinal axial guide; the bushing is surrounded by the hoop and is jammed axially between an inwardly-directed shoulder of the hoop and the fastener ring.

2. A dispenser member according to claim 1 , in which said at least one guide comprises an inner axial groove ( 55 ).

3. A dispenser member according to claim 1 , in which the pusher includes at least one lug ( 49 ) that projects outwards, the lug being engaged in a respective longitudinal axial guide ( 55 ), the lug and the axial guide forming the blocking means for preventing turning.

4. A dispenser member according to claim 3 , in which the axial guide ( 55 ) is closed at its top end, such that the lug ( 49 ) butts against the guide end when an attempt is made to remove the pusher from the actuator rod, thereby preventing the pusher from being removed from the actuator rod.

5. A dispenser member according to claim 4 , in which the hoop includes a top end formed with an inwardly-directed shoulder ( 62 ) that closes the top end of the groove ( 55 ) formed in the bushing ( 5 ).

6. A dispenser member according to claim 1 , in which the hoop ( 6 ) includes fastener profiles ( 65 ) on or in its inside wall, the profiles coming into engagement with the bushing ( 5 ) so as to prevent it from turning in the hoop.

7. A dispenser member according to claim 6 , in which the profiles ( 65 ) also come into engagement with the fastener ring ( 2 ) so as to prevent the hoop from turning on the fastener ring.

8. A dispenser member according to claim 1 , in which the hoop is made of metal and the bushing is made of plastics material.

9. A dispenser member according to claim 1 , in which the blocking means are formed by the hoop.

10. A fluid dispenser comprising a reservoir ( 3 ) and a dispenser member according to claim 1 , the reservoir presenting a cross-section that is not circular.

11. The dispenser member according to claim 6 , wherein the fastener profiles are splines or grooves.

12. A fluid dispenser member for associating with a fluid reservoir ( 3 ), said member comprising:

a body;

a fastener ring that holds the body in stationary manner relative to the reservoir;

a covering hoop engaged in stationary manner around the fastener ring;

an actuator rod axially movable down and up in the body; and

a pusher that is mounted on the actuator rod, the pusher being provided with a dispenser orifice;

a blocking mechanism secured to the hoop so as to prevent the pusher from turning on the actuator rod relative to the body, and consequently relative to the reservoir, such that the pusher is movable only axially, the blocking mechanism comprising a guide bushing that is received in stationary manner in the hoop and that is engaged around the pusher, the bushing forming at least one longitudinal axial guide; the bushing is surrounded by the hoop and is jammed axially between an inwardly-directed shoulder of the hoop and the fastener ring.
