Abstract:
1. A device for closing a container, suitable for containing a first component to be introduced into the container in addition to a second component contained in said container, comprising at least a tank suitable for containing said first component, a mobile thruster for opening the tank, a stable closing portion for the tank and provided with a closure able to cooperate with a neck of the container releaseably clamping with said container, said closing portion being suitable for housing slidingly inside the closing portion at least a part of said mobile thruster and including an opening for the passage of said mobile thruster toward said tank, said mobile thruster being selectively mobile between a first raised position of non-interference with the tank and a second lowered position in which said mobile thruster opens the tank so as to allow the passage of the first component inside the container, said closing portion having an annular surface facing toward the inside of the container when the closing portion is closed on the container, which surrounds said opening extending radially from said opening to said closure, said tank being stably associated with said annular surface, wherein 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 and wherein the device comprises a safety element 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; and wherein said closing portion also comprises an annular rib that extends from the annular surface, in an intermediate position between said opening and said closing means, in order to define, on an external side, an annular interstice delimiting a first crown of the annular surface in which a part of the neck of the container is housed, for the closing cooperation with said closing means, so that an upper annular band of the neck cooperates with said annular rib, and, on an internal side, a second crown of the annular surface, for the stable positioning of the tank.
