Abstract:
1. A fluid dispenser comprising a first fluid pump dispenser member ( 1 ) associated with a first fluid reservoir ( 15 ), said first member comprising a first actuating rod ( 11 ) mounted to move along a first rod axis between a rest position and an actuated position, and a second fluid pump dispenser member ( 2 ) associated with a second fluid reservoir ( 25 ), said second member comprising a second actuating rod ( 21 ) mounted to move along a second rod axis between a rest position and an actuated position, the first rod ( 11 ) having a free end ( 111 ) pointing in a first direction and the second rod ( 21 ) having a second free end ( 211 ) pointing in a second direction, the two members being disposed one relative to the other with the first and second rod axes extending parallel and with the first direction being opposite to the second direction, so that one dispenser member is disposed upside down relative to the other dispenser member, at least one of the reservoirs being an airless reservoir, with its volume decreasing as fluid is extracted therefrom, said fluid dispenser being characterized in that one of the dispenser members has an internal return spring that urges the actuating rod towards its rest position, said fluid dispenser being provided with a load adjustment spring ( 215 ) suitable for modifying the actuation load of said member so that the stiffness of the adjustment spring is added to the stiffness of the internal return spring.
