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.
