A functional insert including a body which is provided with at least one flexible flange on the outer surface thereof, for creating a tight connection with the neck, and a functional element. The functional insert is characterised in that: a) it includes an adhesive which is typically carried by the flange and is selected in such a way that it adheres to the neck of the recipient, and b) the adhesive is typically a permanent adhesive selected in terms of its consistency or viscosity such that it only squeezes out under stress. In this way, any axial displacement towards the top of the functional insert is prevented by fixing the body to the neck of the recipient by means of an adhesive contact region.

The invention claimed is: 1. Functional insert for insertion into the neck of a bottle through an opening, comprising: a body constructed and arranged for insertion into the neck by force fitting, the body comprising a cylindrical wall having a central axis coincident with the central axis of the neck when the body is inserted into the neck, and normal to the opening, the cylindrical wall defining an outer surface, with at least one flexible rib on the outer surface extending radially outwardly with respect to the central axis, for forming a sealed junction with an inner surface of the neck when the body is inserted into the neck, the rib including an upper surface, a functional element, and an adhesive supported on at least one of the upper surface of the rib and the outer surface of the wall above the upper surface of the rib, the adhesive selected to bond to the neck and having a consistency or viscosity such that the adhesive will only creep under a stress that compresses the adhesive between the rib and the body when, with the body inserted into the neck, the rib curls, the adhesive being present in an amount sufficient that the adhesive comes into contact with the neck so as to fix the body to the neck at an adhesive contact area and thereby prevent upward axial displacement of the body under axial stress. 2. Insert according to claim 1, wherein the cylindrical wall comprises at least two ribs, the adhesive being disposed between two ribs, or on each rib. 3. Insert according to claim 1, wherein the adhesive forms a ring, such that the contact area is circular. 4. Insert according to claim 1, wherein the adhesive forms a plurality of discontinuous deposits, so as to form a plurality of discontinuous continuous contact areas. 5. Insert as claimed in claim 1, wherein the adhesive is a permanent, hot-melt adhesive. 6. Insert as claimed in claim 1, wherein the adhesive is activatable or crosslinkable, once the insert has been placed in the said neck. 7. Insert according to claim 6, wherein the adhesive includes a setting agent or activator. 8. Insert as claimed in claim 1, wherein the adhesive is in the form of micro-balls that release the adhesive when the functional insert is placed in the neck, or is an adhesive that is activated when the functional insert is placed in the neck. 9. Insert as claimed in claim 1, wherein the adhesive is bondable to glass, and wherein the contact area of the adhesive is between 20 and 500 mm2, such that the insert remains fixed in the neck under an axial force equal to at least 0.5 daN. 10. Insert as claimed in claim 1, wherein the functional element forms a pouring spout. 11. Insert as claimed in claim 1, wherein the functional element forms an anti-refill device or an anti-fraud device. 12. Insert as claimed in claim 1, additionally comprising a reversible assembly means for temporarily fixing the functional insert to a cap or to a sealing insert of a cap, the axial stress corresponding to at least the stress necessary to separate the cap or the sealing insert from the functional insert when the cap is opened. 13. Closing cap comprising a shell provided with a skirt and a sealing insert fixed to the shell, and a functional insert according to claim 1 wherein the sealing insert or the shell and the functional insert comprises complementary reversible fixing means. 14. Closing cap according to claim 13, wherein the shell is metallic or is made of plastic. 15. Method for manufacturing a cap according to claim 13, comprising the steps of: a) supplying the functional insert, the adhesive and the closing cap, b) depositing or applying the adhesive on the functional insert, and c) fixing the functional insert to the sealing insert or to the shell, such that the adhesive is protected from any external contact by the skirt of the shell, enabling the cap to be manipulated without risk of damage. 16. Insert as claimed in claim 1, comprising a plurality of said flexible ribs, with adhesive disposed on at least one of the upper surface of at least one of the ribs and the outer surface of the wall above the upper surface of at least one of the ribs.
