ABSTRACT:
A safety cap (1) particularly suited for closing containers having an essentially cylindrical shape and containing medicines or dangerous substances consists of an inner element (10) which is tightened on the container (40), an outer element (30) placed over the inner part (10) and a central push button (20) positioned between the inner element (10) and the outer element (30). When the cap is turned in the tightening direction, the cap is closed; on the other hand, in order for the container to be opened, the cap must be turned in the opposite direction while the central push button (20) is simultaneously pressed. The central push button (20) acts as a transmission element between the outer element (30) and the inner element (10). The central push button (20) can be reached through a hole (37) at the center of the flat top surface (38) of the outside element (30). The hole (37) includes a safety seal consisting of a disc (60) connected with the outside element (30) by extensions (61) which will break under pressure. The cap (1) has limited overall radial dimensions and safety properties against unwanted openings, especially by children or handicapped people.
