Safety closure for containers

A safety closure for containers comprising a cover and an internal element, the internal element being formed by a constraining portion and by a covering portion, that after use may be positioned again on the container, the covering portion and the constraining portion being interconnected by means of at least a first preferential breakage zone which, when intact, joins them to each other, the constraining portion being provided with blocking means at the neck of a container with which the closure is intended to be associated, and first removable constraining means associated with the cover, the internal element having sealing means which, at least when the seal is intact, preserve the container content integrity;

• wherein the covering portion has an annular groove adapted to cooperate with a free edge of the container for the reciprocal centering between the covering portion and the container, when the covering portion is on the container, and/or wherein the covering portion has removable anchoring means with said container and/or with said constraining portion, and/or wherein said removable anchoring means comprises at least one edge adapted to cooperate in an undercut with a flange suitably located on said container and/or on said constraining portion.
