Abstract
A perfected drain device, essentially characterized by the fact that it is constituted by a cup integral with a lateral drainage duct and closed by its base, from whose geometric center emerges an internal cylindrical housing provided with a rose step, capable of supporting a threaded rod integral with a cover sheet whose surface appears orified; it being provided that the body of the device itself forms, around the mouthpiece, a peripheral horizontal cornice, on which the covering sheet optionally rests upon assembly.
