Abstract: The closure cap for a container comprises an internal skirt (16) comprising a bore (16b) provided with at least one helical screw thread (19) for screwing said cap onto the container, an external skirt (18) radially surrounding said internal skirt at least partially, and a front wall (14) from which said internal and external skirts extend. The cap is produced by moulding at least one synthetic material. At least one recess (30) is formed on an outer surface (16a) of the internal skirt, remaining axially away from a front end face (16c) of said skirt.

Abstract: The closure cap for a container comprises an internal fastening skirt (16), an external skirt (18) radially surrounding said internal skirt at least partially, and a front wall (14) from which said skirts extend. The internal skirt (16) has a variable thickness in the direction of its axial length, said thickness being at a minimum at least for a proximal portion (22) of said skirt which extends from the front wall (14). The internal skirt (16) comprises the proximal portion (22) with a thickness E that is substantially constant, a distal portion (24) with a thickness E2 that is substantially constantand greater than the thickness E1, and a connecting portion (26) that connects the proximal portion and thedistal portionand has a variable thickness E3 along its length. The axial length of the proximal portion (22) of the internal skirt varies around the circumference of said skirt.
