The device comprises a first container (1), for a first product (A), provided with an outlet orifice (2), and a second container (18), for another product (B), provided with another outlet orifice (6). The first container (1) comprises a cylindrical body (3) open at one end and closed at its other end by a lid (4) provided with a pipe (5) comprising the outlet orifice (6) of the second container. A first piston (7) delimits with the lid (4) and the body (3) a chamber (8) for the first product (A); a second piston (12) is fixed to the end of the pipe (5). The second container (18) includes a cylindrical body (19) whose concavity faces that of the first container (1). The cylindrical body (19) of the second container is engaged inside the body (3) in such a way as to be able to move in it whilst pushing the first piston. The second piston (12) is applied in a fluid-tight manner at its periphery against the inside surface of the second container (18). The pushing of the second container (18) into the first one (1) causes a separation of the two pistons, which results in the expulsion of the products in a predetermined proportion. <IMAGE>
