A separation line is provided on the side wall for defining: a retaining ring intended to remain anchored to a neck of the container, and a closure element which can removably engage the neck, so as to open or close the container. The separation line extends about the axis and is circumferentially interrupted so as to leave a joining portion between the retaining ring and the closing element. The cap further has an incision line which extends transversally to the axis between the separation line and a free edge of the retaining ring, so that between the separation line and the incision line two connecting bands are defined, the connecting bands joining the retaining ring to the joining portion. The connecting bands have a radial thickness measured in a radial direction and a height measured parallel to the axis. The ratio between the height and the radial thickness of the connecting bands is greater than, or equal to, 1.4 and is less than, or equal to, 6.5. ## Claims ### Claim 1 A cap for a container, comprising a side wall extending about an axis and a transversal wall arranged at an end of the side wall, a separation line being provided on the side wall for defining: a retaining ring intended to remain anchored to a neck of the container, and a closure element which can removably engage the neck, so as to open or close the container; wherein the separation line extends about the axis and is circumferentially interrupted so as to leave a joining portion between the retaining ring and the closure element, the cap further having an incision line which extends transversally to the axis between the separation line and a free edge of the retaining ring, so that two connecting bands are defined between the separation line and the incision line, the connecting bands joining the retaining ring to the joining portion, the connecting bands having a radial thickness measured in a radial direction, the connecting bands further having a height measured parallel to the axis, and wherein the ratio between the height and the radial thickness of the connecting bands is greater than, or equal to, 1.4, said ratio being less than, or equal to, 6.5. ### Claim 2 (depends on 1) A cap according to claim 1, wherein the height of the connecting bands is greater than, or equal to, 1 mm and is less than, or equal to, 5.5 mm. ### Claim 3 (depends on 1) A cap according to claim 1, wherein the radial thickness of the connecting bands is greater than, or equal to, 0.35 mm and is less than, or equal to, 1.8 mm. ### Claim 4 (depends on 1) A cap according to claim 1, wherein the radial thickness is greater than, or equal to, 1.1 mm and less than, or equal to, 1.8 mm, the height being greater than, or equal to, 1 mm and less than, or equal to, 3.2 mm. ### Claim 5 (depends on 1) A cap according to claim 1, wherein the radial thickness is greater than, or equal to, 0.35 mm and less than, or equal to, 1.1 mm, the height being greater than, or equal to, 3.2 mm and less than, or equal to, 5.5 mm. ### Claim 6 (depends on 1) A cap according to claim 1, wherein the separation line and the incision line are cut lines. ### Claim 7 (depends on 1) A cap according to claim 1, wherein along the separation line a plurality of breakable bridges is provided, along the incision line a plurality of breakable elements being provided, the breakable bridges and the breakable elements being intended to break the first time the cap is opened. ### Claim 8 (depends on 7) A cap according to claim 7, wherein the breakable elements are arranged in positions angularly offset about the axis relative to the breakable bridges. ### Claim 9 (depends on 1) A cap according to claim 1, wherein the incision line lies in a plane arranged perpendicularly to said axis, when the closure element is in a closed position. ### Claim 10 (depends on 1) A cap according to claim 1, wherein the joining portion has an angular dimension, measured about the axis, greater than, or equal to, 30° and less than, or equal to, 110°. ### Claim 11 (depends on 1) A cap according to claim 1, wherein the incision line has an angular extension, measured about the axis, greater than, or equal to, 120° and less than, or equal to, 250°. ### Claim 12 (depends on 1) A cap according to claim 1, wherein the separation line is positioned at a distance from the free edge of the retaining ring which is greater than, or equal to, 2 mm and less than, or equal to, 6.5 mm. ### Claim 13 (depends on 1) A cap according to claim 1, wherein the incision line is arranged at a distance from the free edge of the retaining ring which is greater than, or equal to, 1 mm and less than or equal to, 5 mm.
