(54)	Mechanical Filling process of a container for cosmetic products

(57) Mechanical filling process of a container for cosmetic products, wherein:

during a first phase, a doughy, hot cosmetic product is fed, under pressure (P1), into a chamber (20) which has a volume variable between zero and the final value, the chamber (20) is also provided with a mobile wall (21a),
and during a second phase, the product, which has been fed into said chamber (20), is cooled;
the process is characterised in that:
the chamber (20), fed by the filling product, is the chamber of a forming die (17); the mobile wall (21a) of the chamber (20) is subjected to a predefined counter-pressure (P2) during the first phase, and
during a third phase, the product (28), which has been held and cooled into said chamber (20) of said die (17), is transferred into the cup (34) of a final container (33).
