Plunger mechanism for the distribution of creams and ointments, essentially constituted by a tube whose end is coupled on the internal face of the cap of the bottle and inside which a helical spring against which a piston rests is disposed. In the lower part of the tube a ball valve is disposed and the piston also has in its center another similar valve communicating with the piston rod of said piston, which is hollow and extends through a bent branch in the landfill of exit.
