Dispenser for fluid cosmetic products

An assembly for packaging and dispensing of fluid cosmetic products, comprising:

• a tubular body forming a longitudinal container intended to contain said products, said tubular body comprising a side wall, an open upper end, and an opposite lower end closed by a bottom;
• a dispensing head sealing said upper opening and having at least one outlet orifice for the products;
• a threaded axial rod cooperating with a first piston able to be moved in axial translation inside said body under the effect of a rotation of said rod, said rod being a hollow rod forming at least part of an axial conduit between the bottom of said container and the at least one outlet orifice of the dispensing head, said axial rod cooperating in rotation with said dispensing head in such a way that a relative manual rotation of said application head with respect to the container drives a movement of said first piston toward the bottom of the container,
• the assembly wherein the threaded axial rod cooperates with a second piston arranged above the first piston and able to be moved in axial translation inside said body under the effect of the rotation of the rod toward the dispensing head in a direction counter to that of the first piston, at least one second conduit ensuring fluidic communication between the opening of the container and the at least one outlet orifice of the dispensing head.
