The device for packaging and dispensing a product comprises a container provided with at least one variable volume compartment, and a dispensing head fastened to the container. The dispensing head comprises a mounting base, an internal piston that is movable in translation along a displacement axis Y-Y′ and delimits, inside said base, first and second pumping chambers, and at least one actuating rod that extends through the pumping chambers and the piston and projects from either side of the mounting base. The actuating rod internally delimits a first feed duct in communication with a first outlet orifice of the dispensing head and a second feed duct separate from said first duct and in communication with a second outlet orifice of said head.
