Closing cap for a container

A closing cap (1) for a container (2) comprising:

• an outer shell (3) which extends along a longitudinal axis (X) and comprises a lateral wall (301), which extends about the axis (X), in particular having a shape which is tubular and coaxial with the axis (X), and an end wall (302;
• 317), which closes the lateral wall (301) at one end for delimiting a concavity;
• wherein the lateral wall (301) is internally provided with a coupling structure (303), configured for removably coupling the cap (1) to a neck (201) of the container (1) in such a way that the cap (1) is movable from a closing position, in which the cap (1) closes a mouth (202) of the container (2), to an opening position;
• an inner component (4;
• 4′) positioned for closing the mouth (202) of the container (2), when the cap (1) is in the closing position, comprising a closing element (401, 401′, 402) provided with an inner portion (401;
• 401′), which is configured, in use, for facing the mouth (202), and an outer flange (402), extending externally relative to the inner portion (401;
• 401′), which is configured for fixing to the outer shell (3);
• a chamber (5), suitable for containing a product (P) intended to be supplied into the container (2) through the mouth (202), which is at least partly delimited by the inner portion (401;
• 401′);
• wherein the cap (1) comprises an opening promoting assembly (6) and the inner portion (401;
• 401′) comprises a breakable portion (403), the opening promoting assembly (6) being configured for axially stressing the breakable portion (403) in such a way as to create a supplying outlet (7) in the inner portion (401;
• 401′) and to make the product (P) come out of the chamber (5), supplying the product (P) into the container (2) through the mouth (202).
