CLAIMS

1 . A method for making a customised crown cap, characterised in that it comprises the following steps:

making a shell (1 ) defining the body of the crown cap, having the circular upper face (2) configured with a recessed portion (3) positioned and included inside the perimeter of the upper face (2);

making a personalising element (10) having dimensions corresponding to the recessed portion (3) and having, at its upper surface (1 1 ), identification means (12);

- inserting the personalising element (10) inside the recessed portion (3) and relative stable association.

2. The method according to the preceding claim, wherein the personalising element (10) has a circular shape.

3. The method according to claim 1 or 2, wherein the step of making a personalising element (10) comprises the steps of:

preparing a sheet of plastic material having a mainly planar extension;

printing a plurality of identification elements and/or decorations on the sheet;

- cutting the sheet into a plurality of portions, at least at a part of the identification elements and/or decorations, to make a corresponding plurality of personalising elements (10).

4. The method according to any one of the preceding claims, wherein the sheet of plastic material is a sheet of thermoplastic material.

5. The method according to any one of the preceding claims, wherein the step of inserting the personalising element (10) inside the recessed portion (3) comprises a step of gluing the personalising element (10) inside the recessed portion (3).

6. The method according to any one of the preceding claims, wherein the step of making a shell (1 ) comprises the following steps:

a) making a capsule equipped with a plurality of corrugations

defining teeth of the crown cap;

b) making a recessed portion (3) on the circular upper face (2) of the capsule.

7. The method according to the preceding claim, wherein the step of making a capsule equipped with a plurality of corrugations defining teeth of the crown cap is made, in terms of time, before the step of making a recessed portion (3) on the circular upper face (2) of the capsule.

8. The method according to claim 6 or 7, wherein the making of a recessed portion (3) on the circular upper face (2) of the capsule (1 ) comprises a step of placing the capsule in contact with a die (P), and subjecting it to the pressing action of a punch (M).

9. The method according to the preceding claim, wherein the punch (M) has an axially-symmetrical shape and has on a radially outer portion (40) a prominent edge (41 ).

10. The method according to the preceding claim, wherein the prominent edge (41 ) of the punch (M) is connected to a central face (42) by an inclined surface (43), the inclined surface (43) being inclined relative to a surface (44) of the central face (42) at an angle of between 15° and 50°.

1 1 . The method according to the preceding claim, wherein the prominent edge (41 ) of the punch (M) is connected to a central face (42) by an inclined surface (43), the inclined surface (43) being inclined relative to a surface (44) of the central face (42) at an angle of between 20° and 40°.

12. The method according to any one of the preceding claims and claim 8, wherein the die (P) has on a radially outer portion a perimeter recess (45).

13. A closing capsule, comprising a shell (1 ) defining the body of the crown cap, equipped with a plurality of corrugations (46) defining the teeth of the crown cap characterised in that it has a circular upper face (2) configured with a recessed portion (3) positioned and included inside the perimeter of the upper face (2), the recessed portion (3) being a continuous portion radially inside an axis of symmetry of the shell.

14. The capsule according to the preceding claim, wherein the recessed portion (3) comprises a first central surface (46) which terminates, at a radially outer edge, with a surface (47) inclined relative to the first central surface (46).

15. The capsule according to the preceding claim, wherein the inclined surface (47) is inclined relative to the first central surface (46) at an angle of between 15° and 50°.

16. A closing cap (T), comprising a closing capsule according to any one of claims 13 to 15 and a personalising element (10) coupled to the shell (1 ) and positioned inside the recessed portion (3).
