Claims

1. The connection device between the vessel (2) and the container (2 '), and the vessel contains a neck (3), the opening of which (3a) is closed by a stopper (4), containing the base (5) mounted on the vessel (2) and having a continuation in the form of a flange (9) forming an internal bore (A), and a piston (10) made with the possibility of sliding in the internal bore in the space between its release position relative to the tube and the position of the gear, in which the hollow needle (11) is mounted on the piston passes through the cork, characterized in that it includes the edge of the hermetic tizatsii (22; 72; 122) provided on the inner surface (8d; 109a) of the bore (A) opposite the piston (10; 110) or on the surface (60d) of the piston (60), the edge being made in such a way as to provide sealing emphasis on the piston (10; 110) or on the inner surface (58e) of the bore in the piston transmission position.

2. The device according to p. 1, characterized in that the base (5) contains a wall (8) of the stop in the outer part (4e) of the plug (4), and the edge (22) is made on the surface (3d) of the wall (8) located in the direction of the piston (10).

3. The device according to claim 1, characterized in that the edge (72) is made on the front surface (60d) of the piston (60) located in the direction of the plug (4)
4. The device according to claim 1, characterized in that the edge (122) is made on the inner radial surface (109a) of the flange (109) or on the outer radial surface (110e) of the piston (110).

5. The device according to any one of the preceding paragraphs, characterized in that the edge (22; 72; 122) is in cross section an asymmetric profile (α, β) that defines the preferred direction of its deformation.

6. The device according to any one of the preceding paragraphs. characterized in that on the inner radial surface of the flange (9; 59; 109) there is a ring (24; 74; 124) that is continuous in the circumferential direction and interacts with the corresponding circular protrusion (10s; 60s; 110s) made on the outer radial surface of the piston (10; 60; 110), to enable locking of this piston in its gear position.

7. The device according to p. 6, characterized in that the ring (24; 74; 124) is positioned so that it provides a lock of the piston (10; 60; 110) in the position of the sealed edge stop (22; 72; 122) in the piston (10; 110) or into the inner surface (58e) of the bore (A).

8. The device according to claim 6 or 7, characterized in that the ring (24; 74; 124) has an asymmetric cross-section, with the surface (24a) of this ring located in the direction of the open end or mouth (9b) of the bore (A) in less inclined (δ, β) with respect to the inner radial surface (9a) of the flange (9) than its surface (24b) located in the direction of the plug.

9. The device according to any one of paragraphs. 6-8, characterized in that the ring (24; 74; 124) hermetically seals the annular volume (V ') defined in the bore (A) around the front of the piston (10; 60; 110) in its transmission position, from the outside atmosphere.

10. A system comprising a vessel (2) containing a product, this vessel containing a neck (3), the opening of which (3a) is closed with a plug (4), and a connection device (5-24; 60-76; 109-124 ), characterized in that the connection device mounted on the vessel is made according to any one of paragraphs. 1-9.
