• the hinge region comprising a pair of elongate hinge elements spaced apart from each other, and a ratchet-like member disposed therebetween,
• the hinge elements being integrally formed with the shell and the top panel, and each having a lower portion and an intermediate portion having an inwardly sloping outer face, thereby providing an upper portion having, relative to a wall thickness of the lower portion, a wall of reduced thickness;
• the ratchet-like member being integrally formed with the shell and having a body with an outer contour comprising a lower, an intermediate and an upper portion, and an inner contour comprising a lower, an intermediate and an upper portion,
• wherein the intermediate portion of the outer contour comprises at least one inward curvature for guiding an end portion of the tongue during opening of the lid, and the upper portion of the outer contour comprises an outward curvature for providing an abutment for the end portion of the tongue in a final open position of the lid.
