• Figure 5 is a perspective view of the inner cap with particular demonstrate the means of one ratchet (14) placed on the outer surface of the upper end wall of the inner cap type toothed crown.
• the eight teeth (17) forming the crown are spaced from each other, so that the teeth the crown of the outer cap can be embedded between the teeth of the crown of the inner cap when the outer cap is soi ⁇ mis at an axial pressure and then a primer rotation.
• Each tooth (17) has a vertical plane (18), which corresponds to a plane of radial section of the inner cap, and an oblique opposite plane (19).
• the vertical plane (18) allows the latching with the corresponding vertical plane of the tooth of the toothed ring located on the inside of the outer cap, during unscrewing while the oblique plane instead raises the corresponding plane of the tooth which it is opposed during the screwing operation.
• This particular shape of the teeth is designed so that the outer plug, when not subjected to axial pressure, but only subjected to a rotational movement, can rotate without causing the internal plug, the teeth of the crown of the outer cap can slide on the teeth of the ring of the inner cap, if they are in contact with them, without snapping into each other.
• FIG. 6 is a section along a plane at the junction between the upper part of the first opening control ring and the lower part of the external plug of the closure device, showing the three notches (9) and the 8 links or scored bridges ⁇ 8 ⁇ connecting the upper circumference of the first opening control ring to the lower circumference of the outer cap skirt.
• a safety closure device of a container whose mouth is provided with an external screw thread a device that is child-proof and also includes a first-opening indicator and a desiccant element.
