The threaded cap is provided with a guarantee ring (3) which is connected with the body (2) or the cap by thin rims (4) The maximum width (d) of the ring is located next to this rim, and then decreases towards the top. The height (h) of the ring (3) does not exceed half of the height of the body (2). The ring is thereby strong enough to resist crushing in the radial direction, while using a minimum amount of material. It covers a serrated portion (6) of the body (2), which is used, after its removal, for screwing the body (2). The external surface of the ring (3) and of the uncovered portion (2d) of the body (2) is smooth, which makes almost impossible the unscrewing of the caps with a view to taking away the contents of the container without breaking the thin rims (4). |
