A mechanical twist-dispenser (1) having a plurality of product compartments (6) within a housing, a rotatable screw member (9) axially disposed within each product compartment, and a piston (13) axially slidably disposed within each product compartment. The piston (13) has a central threaded aperture which cooperates with the screw member to move the piston axially within its product compartment with the relative rotation of its associated screw member. A master gear (15) is positioned between and contacts each screw member gear (12) such that the rotation of the master gear causes the screw member to rotate and subsequently move the piston axially within the product compartment so as to dispense the product within each compartment.
