摘要：
A fluid distribution device (1405) for distributing a fluid product having: a distribution outlet (1411) from which the fluid product can be distributed, a fluid product supply, a distribution member (1408) mounted for the movement in an upward direction of distribution along an axis (XX) from a first position to a second position that causes a dose of the fluid product in the supply to be distributed from the distribution outlet, and an operable drive member with the finger (1420) mounted for pivot movement around a lower end of the drive member in a drive direction that is generally transverse to the axis, in which the drive member has at least one cam surface ( 1422) distanced from the lower end and the distribution member has at least one cam follower surface (1492), in which the drive member is moved so that it can pivot in the drive direction to cause the at least one cam surface to rest against the at least one cam follower surface to force the at least one cam follower surface to travel over the cam surface to moving the distribution member in the distribution direction upward from the first position to the second position, characterized in that: the at least one cam surface has a coupling section (1423a), oriented at a first angle with respect to the axis, and an adjacent unit drive section (1423b), which is oriented at a second angle with respect to the axis that is larger than the first angle, the device is configured and arranged such that, during use, the at least one surface cam follower moves successively over the coupling sections and the drive sections of the at least one cam follower surface, in the movement or pivot of the drive member in the drive direction, the distribution member is moved from the first position to the second position, the first angle is selected such that a minimum driving force is required to be applied to the driving member to cause the at least one cam follower surface to travel over the coupling section in the drive sectio
