CLAIMS

1. Opening/closing device (1 ) for a container (100) for pourable products, having at least one perforate portion (101 ), said opening/closing device comprising a collar (2) combinable with said container at said perforate portion, a cap (3) constrainedly movable by first guiding means (40), which are interposed between said cap (3) and said collar (2), on the outer surface (2a) of said collar (2), and a cutting element (5) constrainedly movable by second guiding means (60), which are interposed between said cutting element (5) and said collar (2), inside said collar (4) for severing said perforate portion, said device (1 ) further comprising pushing means (7) for said cutting element (5), which are actuated by said cap (3) during at least its first displacement on said outer surface (2a) of said collar (2), for promoting the displacement inside said collar of said at least one cutting element in the direction of said perforate portion, wherein said cap (3) is provided with at least one through hole (32) for pouring said pourable product and with at least one lid (10) integrally constrained to said cap and adapted to seal, or open, the passage of said at least one through hole (32), said first guiding means (40) only rotatably constraining said cap (3) to said collar (2), characterized further comprising means (1 1 ) for limiting the rotation of said cap with respect to the outer surface (2a) of said collar (2) between a first assembled position (P1 ) for said opening/closing device and a second locked position (P2) of said cap (3) on said collar (2).

2. Device according to claim 1 , characterized in that said limiting means (1 1 ) comprise at least two parts, which can be reciprocally engaged and are respectively integral with said cap and said collar.

3. Device according to claim 2, characterized in that said limiting means (1 ) comprise at least one locking tooth (1 1 ) which can be engaged in at least one corresponding seat (12), at least when said cap is in said second position, said at least one locking tooth protruding inside said cap and said at least one seat being defined on said outer surface of said collar, or vice-versa.

4. Device according to one or more of claims 1 to 3, characterized in that the

angular range between said first position and said second position is between 180 and 360°.

5. Device according to one or more of claims 1 to 4, characterized in that said first guiding means (40) comprise a first protruding radial portion (41 ) and a second protruding radial portion (42), wherein said first protruding portion is integral with the outer surface of said collar and said second protruding portion is integral with the inner surface (3b) of said cap (3) and adapted to brush against said first protruding portion during the rotation of said cap with respect to said collar, said first protruding portion and/or said second protruding portion being elastically deformable at least when said cap is combined with said collar during the assembly of said opening/closing device (1 ).

6. Device according to one or more of claims 1 to 5, characterized by comprising a retaining ring (80) integrally constrained at the lower end of said cap by a plurality of frangible bridges, said frangible bridges being severed at least when said cap is displaced from said first assembled position.

7. Device according to any one of the preceding claims, characterized in that said lid (10) is made in one piece with said cap.

8. Device according to any one of the preceding claims, characterized in that said cap (3) comprises a pouring spout (31 ), said through hole (32) being made at the upper final end (31 b) of said pouring spout.

9. Device according to any one of the preceding claims, characterized in that said lid is hinged to said cap by a plastic hinge combined with the side surface of said cap.

10. Device according to claim 9, characterized in that said plastic hinge is arranged on said side surface (3c) in an angular position so that at least when said cap (3) is in its second locked position, said lid (10), when open, is on the part of the container opposite the side(s) of the container closest to said collar.

11. Method for the first opening of a container for pourable products provided with an opening/closing device according to one or more of claims 1 to 10, comprising the steps of:

a) displacing said cap with respect to said collar;

b) causing, during said step a), the displacement of said cutting element in the direction of said perforate portion of said container for severing it;

said method further comprising subsequently to said step b), the step c) of raising said lid integral with said cap for pouring the product contained in said container, characterized by further comprising the step d) of limiting the displacement of said cap between a first assembled position for said opening/closing device and a second locked position (P2) of said cap to said collar.

12. Method according to claim 11 , characterized in that said step a) comprises the step a1 ) of rotating said cap with respect to the outer surface of said collar between said first position and said second position.

13. Method according to claim 11 or 12, characterized by the fact that said step (c) comprises the step of turning the lid with respect to the cap.
