Closing device characterized by comprising a lid molded from a material having adequate elastic characteristics in which essentially a central cylindrical lower rim has been provided, from which emerge protruding bodies of arc-circle section concentric with the expressed flange on whose external faces fillets of the same thread have been made, these sectors being able to adapt to a cylindrical neck threaded for this purpose provided in the box on which the cover must be adapted; all in such a way that thanks to the elasticity of the constituent material of the cover the expressed adaptation can be carried out either by normal screwing of the expressed threaded sectors in the said cylindrical neck or by snap-fitting the inside thereof through the consequent elastic deformation thereof.
