The invention relates to a closure for containers with evidence of first opening. Specifically, the invention is characterized by a closure comprising an inner cap and an outer cap interconnected to one another to allow spacing to be set between the two once the first opening of the closure takes place. This spacing generates a visual change in the appearance of the closure, with evidence of the first opening being shown. To ensure the evidence of the first opening of the closure, the invention combines a first groove with a helical segment with a flange that moves through said first groove until reaching a housing in which its movement is irreversibly blocked by means of a flexible prolongation. The movement of the flange in the first groove defines the transition between a first position before the first opening and a second position after the first opening of the closure.
