The distributor (1) comprises a cylindrical reservoir (2) with a base (20) and a dome-shaped top (22). A small dish (40) crimped onto the dome supports a distribution valve (4) having a control rod (41) passing through a central orifice (48) in the dish. The control rod is connected to a push button (5) which has a distribution orifice (50) connected to the control rod through an angled distribution channel (51). Inside the reservoir is a piston (3) having a body (30) and a cylindrical skirt (31) which slides on the reservoir internal cylindrical wall (23). The piston forms with the wall and the bottom a first compartment (V) filled with propellant gas. A second compartment formed by the piston the wall and the dome is filled with the liquid (L).
