A dispenser comprising: a housing; a reservoir positioned in the housing that contains a supply of a fluid to be dispensed; a dispense mechanism configured to dispense a discrete quantity of the fluid from the reservoir, the dispense mechanism comprising: a lever member having a first lever section accessible on an exterior side of the housing, a second lever section, and a fulcrum connected between the first lever section and the second lever section, the fulcrum pivotally supported within the housing so that the lever member is moveable between a rest position and a dispense position upon application of an input force to the first lever section; and an actuator configured to provide two contact points (215, 217) with the second lever section as the lever member is moved from the rest position to the dispense position, the actuator comprising a first contact surface that contacts the second lever section at a first one of the two contact points and a second contact surface that contacts the second lever section at the second of the two contact points, such that the mechanical advantage provided at the first contact point is greater than the mechanical advantage provided at the second contact point, such that an output force applied to the actuator at the first contact point is greater than an output force applied to the actuator at the second contact point, characterised in that the first contact point is located between the fulcrum and the distal end of the second lever section and the second contact point is located at the distal end of the second lever section. a housing;
