Abstract
A fluid dispensing device for dispensing a fluid product having a dispensing member mounted for movement along an axis X-X from a first position to a second position which causes a dose of a fluid product to be dispensed, and a finger-operable actuator member movable in an actuating direction generally transverse to the axis to cause at least one cam surface thereof to cam the dispensing member from the first position to the second position. The at least one cam surface has a commitment section, oriented at a first angle to the axis selected such that a minimum actuating force is required to be applied to the actuator member to cause the at least one cam follower surface to ride over the commitment section onto the drive section. The commitment section of the cam surface is arcuate.
