A combination of a cap (1), a container (2) and a neck (201) of the container (2), wherein the cap (1) comprises a lateral wall (3) extending about an axis (Z) and a transversal wall (4) positioned at an end of the lateral wall (3), a separation line (5′) being provided on the lateral wall (3) for defining:
- a retaining ring (301′), which is configured to remain anchored to the neck (201);
- a closing element (302) removably engageable with the neck (201), so as to open or close the container (2);
- the separation line (5′) extending about the axis (Z) and being circumferentially interrupted so as to leave the retaining ring (301′) and the closing element (302) joined together;
- the retaining ring (301′) comprising:
- a retaining portion (303), which is configured to internally engage with a locking ring (202) of the neck (201) and extends as far as a free edge (304) of the retaining ring (301′);
- a joining portion (305) at which the retaining ring (301′) is joined to the closing element (302);
- a first connecting band (306) and a second connecting band (307), which extend from the joining portion (305) to the retaining portion (303);
- a tab (308), circumferentially interposed between the first connecting band (306) and the second connecting band (307), which protrudes towards the free edge (304);
- wherein the locking ring (202) projects from an outer surface of the neck (201) and extends in a direction parallel to the axis (Z) between an upper end (202c), nearer a dispensing opening (203) of the neck (201) and a lower end (202b);
- and wherein the first and the second connecting bands (306;
- 307) are made of an incision line (7′) which extends between the separation line (5′) and the free edge (304) and comprises a first lateral stretch (702′) and a second lateral stretch (703′) which partially define respectively the first connecting band (306) and the second connecting band (307), wherein, when the closing element (302) is in a closed condition, the first lateral stretch (702′) and the second lateral stretch (703′) are positioned at or above the lower end (202b) of the locking ring (202) towards the dispensing opening (203), so that when the closing element (302) is in an open condition and the first and the second connecting bands (306, 307) keep the closing element (302) connected to the retaining ring (301′), the tab (308) rests on the neck (201) above the upper end (202c) of the locking ring (202) towards the dispensing opening (203);
- and
- wherein the tab (308) is connected to the lateral wall (3) by a hinge band which is transversal to the axis (Z), wherein each of the first and second connecting bands (306, 307) has a first or top portion and a second or bottom portion, wherein the closing element (302) is rotatable about the hinge band from the closed condition to the open condition without the second portion of each of the connecting bands (306, 307) twisting to pass under the respective first portion and be interposed between the first portion and the outer surface of the neck (201) when the tab (308) is resting on the neck (201) and a bottom edge (309) of the tab (308) faces towards the dispensing opening (203) of the container (2).
