A fluid dispenser having: a fluid reservoir, a fluid dispenser member having actuator rod (23) that is displaceable down and up along an axis X, a pusher (4; 4; 4″) that displaces the actuator rod (23), a dispenser endpiece (50) defining a dispenser orifice (51), and a displacement mechanism
A fluid dispenser having: a fluid reservoir, a fluid dispenser member having actuator rod (23) that is displaceable down and up along an axis X, a pusher (4; 4; 4″) that displaces the actuator rod (23), a dispenser endpiece (50) defining a dispenser orifice (51), and a displacement mechanism (6, 4; 6′, 7; 6″, 7, 4″) that displaces the endpiece (50) both in turning about the axis X and in radial translation, the radial distance between the endpiece and the axis X varying as the endpiece turns about the axis X, such that the endpiece is displaceable between an extended position remote from the axis X and a retracted position close to the axis X.

The invention claimed is: 1. A fluid dispenser comprising: a fluid reservoir (1) provided with an opening (11); a fluid dispenser member (2) comprising a body (21) and an actuator rod (23) that is displaceable down and up along an axis X; a fastener ring (3) for fastening the dispenser member on th
The invention claimed is: 1. A fluid dispenser comprising: a fluid reservoir (1) provided with an opening (11); a fluid dispenser member (2) comprising a body (21) and an actuator rod (23) that is displaceable down and up along an axis X; a fastener ring (3) for fastening the dispenser member on the opening of the reservoir; a pusher (4; 4; 4″) that is axially displaceable down and up so as to displace the actuator rod (23); and a dispenser endpiece (50) defining a dispenser orifice (51); displacement means (6, 4; 6′, 7; 6″, 7, 4″) that are suitable for displacing the endpiece (50) both in turning about the axis X and in radial translation, the radial distance between the endpiece and the axis X varying as the endpiece turns about said axis X, such that the endpiece is displaceable between an extended position remote from the axis X and a retracted position close to the axis X, the displacement means comprising a rotary actuator member (4; 7) that turns about the axis X, the endpiece (50) being constrained to turn with said actuator member, and a cam path (62) that is prevented from turning relative to the reservoir (1), the radial distance between the path (62) and the axis X varying along the path, the endpiece (50) being engaged with the cam path in such a manner that it the endpiece follows the cam path while the endpiece is being turned by the actuator member (4; 7), the cam path (62) is formed by a cam element (6″) that is mounted on a ferrule (8) that is mounted in stationary manner relative to the reservoir (1), the cam element (6″) being prevented from turning relative to the ferrule (8), but being capable of being displaced axially, the pusher (4″) being in engagement with the ferrule (8) via a second threaded cam path (84), the pusher (4″) being turned by the actuator member (7), the pusher (4″) being displaced axially relative to the ferrule (8) and to the actuator member (7) by following the second threaded cam path (84) while said pusher is being turned by the actuator member, such that turning the actuator member simultaneously causes the rotary axial displacement of the pusher and the rotary radial displacement of the endpiece. 2. A dispenser according to claim 1, in which the endpiece (50) is connected to the actuator rod (23) via a flexible hose (53). 3. A dispenser according to claim 1, in which the cam path (62) is axially displaceable down and up with the pusher (4; 4″). 4. A dispenser according to claim 1, in which the cam path (62) is stationary relative to the reservoir (1). 5. A dispenser according to claim 1, in which the pusher (4) forms the rotary actuator member, the endpiece (50) being constrained to turn with the pusher. 6. A dispenser according to claim 1, in which the endpiece (50) is constrained to turn with the pusher (4″), the pusher being turned by the rotary actuator member (7) which is a part that is distinct from the pusher, the actuator member being prevented from moving in axial translation. 7. A dispenser according to claim 1, in which the endpiece (50) is disposed in a rotary housing (45; 75) in which it is displaceable radially. 8. A dispenser according to claim 1, in which the cam path (62) is formed by a cam element (6; 6″) that is mounted on the fastener ring. 9. A dispenser according to claim 1, in which the pusher (4″) is axially displaceable in such a manner as to be housed entirely in the actuator member (7) with the endpiece (50) in its retracted position, that is masked by the actuator member. 10. A dispenser according to claim 1, in which the pusher (4″) comprises a body (40) and a cover (49), the body (40) forming a rotary housing (45) for the endpiece (50), the cam path (62) being disposed between the body and the cover. 11. A dispenser according to claim 1, in which the cam path (62) is formed by a cam element (6; 6; 6″) comprising a plate (61) provided with a rib defining the cam path, the endpiece (50) including a groove (52) in which the rib is slidably housed. 12. A dispenser according to claim 1, in which the pusher (4) includes a window (42) through which the cam element (6) is visible. 13. A dispenser according to claim 1, in which fluid dispenser member is a pump or a valve.
