The dispenser includes a housing having a first recess for holding the cartridge, a plunger movable along the longitudinal axis of the first recess, a driver element for selectively engaging and moving the plunger in a forward direction along the longitudinal axis, and a clutch element for and selectively engaging the plunger to restrain movement of the plunger in a rearward direction.
