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.
