A multilayer dose having an axis of symmetry for the realization of multilayer objects by compression molding, constituted by a first synthetic resin and by a fine functional layer 3 imprisoned in said first resin, said layer 3 representing less than 20% of the volume of the dose, the multilayer dose being characterized in that the layer 3 forms the shell of a body of revolution about the axis of symmetry and in that the distance from the layer to the axis of symmetry is variable.
