<p>A device for closing a container, in which to contain a first component to be introduced into the container in addition to a second component, comprising a tank for the first component, a mobile thruster by means of which to determine the opening of the tank, a closing portion stably associated with the tank and provided with closing means able to cooperate with a neck of the container to determine a releasable clamping. The closing portion houses slidingly inside it at least a part of the mobile thruster and has an opening for the passage of the mobile thruster toward the tank. The mobile thruster is selectively mobile between a first raised position of non-interference with the tank and a second lowered position in which it determines the opening of the tank to allow the passage of the first component inside the container. The mobile thruster is made by molding in a single piece with the closing portion, defining a profile of preferential breakage connecting said mobile thruster and said closing portion. A safety element is also provided, made in a single piece both with respect to said mobile thruster and also with respect to the closing portion, to prevent an accidental reciprocal movement of said mobile thruster with respect to said closing portion.</p> |
