Patent ID: 7748580

Claim:
A fluid dispenser head for associating with a fluid reservoir ( 1 ), said head comprising: a stationary base ( 2 ) formed by, or for mounting on, said reservoir; a rotary actuator element ( 3 ) mounted in rotary manner on the base ( 2 ) so as to turn about an axis of rotation between two extreme abutment positions; and a dispenser orifice ( 30 ) that can be closed selectively by turning the element on the base, the dispenser orifice ( 30 ) being situated on the axis of rotation of the element on the base, the two extreme abutment positions defining two open positions of the dispenser orifice separated by at least one position in which the dispenser orifice is closed, the dispenser head comprising axial displacement means ( 221 , 321 ) for axially displacing the element ( 3 ) relative to the base ( 2 ) while turning on the base, the axial displacement means comprising at least one guide path ( 221 ) presenting two sections ( 2211 , 2212 ) that are connected together at a low point ( 2210 ), each of the two sections defining a respective extreme abutment ( 2213 , 2214 ), the two extreme abutments respectively corresponding to the two open positions, and the low point corresponding to the closed position, and the two sections having slopes presenting inclinations or lengths that are different so that the two sections are non-symmetrical with respect to the low point.
