The device according to claim 1, wherein the geometric interference means (13) are obtained along the free lateral edges (14a, 14b) of the spout (8), and are constituted by at least two corresponding interference elements (15a, 15b), elastically movable from a first position of non interference during the extraction of the spout (8), to a second extreme position of geometric interference with the lid (6) of the can. 3. The device according to claim 2, wherein the free edges of the opening (9) present a flap (10) towards the exterior of the spout (8) which rounds its edges and in that the geometric interference means (13) are obtained in correspondence with the flap (10) itself. 4. The device according to claim 2, wherein the interference elements are produced by punching out a lateral wall of the lamina (4). 5. The device according to claim 3, wherein the interference elements are produced by punching out a lateral wall of the lamina (4). 6. The device according to claim 3, wherein the interference elements are produced by folding beaks of the flap outwards. 7. The device according to claim 1, wherein said free edges of the opening (9) present a flap (10) towards the exterior of the spout (8) which rounds its edges. 8. The device according to claim 1, comprising a union (11) of the central part (5) and of the lateral parts (7a, 7b) to the inner face of the lid (6) constituted by a single continuous structure. 9. The device according to claim 2, comprising a union (11) of the central part (5) and of the lateral parts (7a, 7b) to the inner face of the lid (6) constituted by a single continuous structure, wherein said geometric interference means (13) are obtained along the free lateral edges (14a, 14b) of the spout (8), and are constituted by at least two corresponding interference elements (15a, 15b), elastically movable from a first position of non-interference during the extraction of the spout(8), to a second extreme position of geometric interference with the lid (6) of the can. 10. The device according to claim 2, comprising a union (11) of the central part (5) and of the lateral parts (7a, 7b) to the inner face of the lid (6) constituted by a single structure wherein the free edges of the opening (9) present a flap (10) towards the exterior of the spout (8) which rounds its edges and in that the geometric interference means (13) are obtained in correspondence with the flap (10) itself. 11. The device according to claim 1, wherein, during the extraction of the lamina (4), the free portion of the perimeter of the lateral parts (7a, 7b) projects towards the interior of the can and in that the surfaces of said parts are inclined towards the interior of the can, until checked by the inner face of the lid (6). 12. The device according to claim 2, wherein, during the extraction of the lamina (4), the free portion of the perimeter of the lateral parts (7a, 7b) projects towards the interior of the can and in that the surfaces of said parts are inclined towards the interior of the can, until checked by the inner face of the lid (6), wherein, said geometric interference means (13) are obtained along the free lateral edges (14a,
