Abstract

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.

Claims

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 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 with said container, said closing portion being suitable for housing slidingly inside it 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 it determines the opening of the tank so as to allow the passage of the first component inside the container, said closing portion having an annular surface facing, during use, toward the inside of the container, which surrounds said opening extending radially from said opening to said closing means, 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 in that it 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.

2. The device as in claim 1, wherein that 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.

3. The device as in claim 2, wherein the second crown is configured to allow a disposition by gluing or heat-welding of the tank thereon, so that said tank is both in a condition of interference with the travel of the mobile thruster and also facing, during use, toward the inside of the container.

4. The device as in claim 2, wherein characterized the annular rib is tapered, having a section with an axial development that progressively narrows toward the annular surface.

5. The device as in claim 4, wherein the taper of the annular rib defines a determinate angle of inclination comprised between about 3°

and about 10°

, with respect to a reference plane substantially parallel to a central axis of said closing portion.

6. The device as in claim 2, wherein it comprises an annular packing associated with the closing portion.

7. The device as in claim 6, wherein the annular packing is disposed between the annular surface of the closing portion and the upper annular band of the neck.

8. The device as in claim 6, wherein the annular packing is disposed between said tank and an upper annular band of the neck.

9. The device as in claim 1, wherein the closing portion has internally guide ribs cooperating with the mobile thruster in the passage from the first position to the second position.

10. The device as in claim 9, wherein the mobile thruster is provided with sliding teeth able to cooperate with said guide ribs.

11. The device as in claim 9, wherein said guide ribs have an axial development mainly along a helical trajectory.

12. The device as in claim 1, wherein the safety element is connected to the mobile thruster and to the closing portion by means of relative pre-cut segments conformed to facilitate the removal of said safety element.

13. The device as in claim 1, wherein in that it comprises an anti-tampering element associated both with the closing portion and also with the container to selectively prevent the uncoupling thereof.

14. The device as in claim 1, wherein the mobile thruster comprises at least a rod mounted sliding in said closing portion and provided with a first drive end and a second pointed end for breaking the tank.

15. The device as in claim 1, wherein the mobile thruster is formed by walls which intersect orthogonally.

16. The device as in claim 1, wherein in that the mobile thruster has inclined segments.

17. The device as in claim 1, wherein it comprises clamping means configured to determine the mechanical clamping of the mobile thruster in the second position.

18. The device as in claim 1, wherein said tank is made based on a metal associated with a polymer, to guarantee a barrier against humidity and oxygen and the weldability of the closing portion.

19. The device as in claim 1, wherein said tank comprises a planar wall and a hollow protuberance for containing the first component.

20. The device as in claim 19, wherein said planar wall faces toward the mobile thruster and said protuberance faces toward the inside of the container.

21. The device as in claim 19, wherein said planar wall faces toward the inside of the container and said protuberance faces toward the mobile thruster.

22. A container comprising the closing device as in claim 1.
