These the latter are intended to perforate the wall of the packaging on which the device according to the invention will be disposed.
• Note in Figure 1 an area of the lower end of the movable part 4 not provided with teeth. On section views, this area is not visible because it is part of the cut part of part 4.

• This device comprises a pin 30 extending axially in the center of the moving part 4 as well as three connecting rods 32 connecting the central stud 30 to the inner wall of the moving part 4.
• the outer face of the movable part has a shoulder 34 delimiting the cam-type zone of the movable part of the body of this part carrying the teeth 22.
• the base 2 and the moving part 4 are molded in a single operation.
• the part constituted by the base 2 and the movable part 4 is as shown in FIGS. 1 to 3.
• Breakable bridges 35 connect at the level of the opening 10 the base 2 to the movable part 4.
• Both the lower stops 26 that the upper stops 28 of the moving part are located outside of the base 2.
• the outside diameter of the moving part 4 is slightly greater than the diameter of the opening 10 while being however less than the inside diameter of the neck 12.
• the movable part is returned to the interior of the base 4.
• the upper stops 28 then the lower stops 26 therefore pass through the opening 10. This thus engages the movable part 4 towards the inside of the base 2. In this position, the teeth 22 are protected so that they cannot become dull before mounting the base 2 on a package.
• the plug 6 has a bottom 38, a skirt 40, a first chimney 42, a second chimney 44 and a tamper-evident belt 46.
• the skirt 40 extends at the periphery of the bottom 38. It has threads 48 on its inner face intended to cooperate with the threads 14 of the neck 12. There are therefore as many threads 48 on the skirt of the plug as there are threads 14 on the neck 12.
• the first chimney 42 is intended to seal the plug 6. Its outer surface cooperates with the inner surface of the neck 12, at the upper edge 18 to achieve, in known manner, a seal. To guarantee a perfect seal, it is possible to provide a slightly larger diameter for the outside surface of the first chimney 42 than for the inside diameter of the neck 12.

• the second chimney takes the same shape as the part of the movable part 4 located above the shoulder 34.
• this second chimney has the general shape of a cylindrical tube of circular section extending from the bottom 38 and truncated by a plane inclined relative to the bottom 38. The inclination of this plane relative to the bottom 38 corresponds to the inclination of the plane truncating the moving part 4 relative to the opening 10.

• the moving part 4 is then pushed inside the base 2.
• the assembly shown in section in FIG. 4 is thus produced by breaking the bridges 35.
• the second chimney presses on the edge of the moving part 4 which faces it.
• the ribs 20 made at the neck 12 and the grooves 24 produced at the movable part 4 the latter cannot rotate with the plug 6. It can only move in axial translation in the direction causing the teeth 22 to exit.
• the lower stops 26 hinder this translation but do not prevent it not.
• the resistance created by these lower stops 26 is low compared to the resistance exerted on the teeth 22, which, to exit, must penetrate the packaging by crossing the wall thereof in order to provide an opening therein.
• Figures 7 and 8 show a variant of the device shown in Figures 4 and 5. The same references are used here to represent the identical elements.
• the free edge of the chimney 44, opposite the bottom 38 is in the form of a helix.
• This propeller has a pitch h.
• the free end of the movable part 4 opposite the teeth 22 also has an edge in the form of a helix of pitch h.
• the operation of this device is the same as that of the device described above. The only difference lies in the fact that to achieve the complete stroke of the movable part 4 in translation, it is necessary to rotate the plug 6 through 360 ° while in the embodiment of Figures 3 and 4, 180 ° are sufficient .
• This device is also produced in two stages of molding. As before, the moving part 4 and the base 2 are molded in a single step.
• the devices described above are of a low cost price. Indeed, two molding operations are sufficient to achieve them. The investments to be made to produce such a device are therefore limited. In addition, the assembly operations required then to make this device are limited since there is no point in orienting the moving part 4 relative to the base 2. As a result, it can be industrialized at high speed because the operation d orientation is a manufacturing step that would be performed manually.
• this device is very simple. Indeed, for the user who unscrews the cap 6, everything happens as if he was unscrewing a cap from a bottle. Only the torque to be exerted to unblock the plug 6 during the first opening is greater than for unscrewing an ordinary plug.
• the screw cap described above is a cap having a tamper-evident ring with inverted lips. Another type of inviolability can be chosen. It is even possible to have a stopper here without a tamper-evident device.
• the grooves and ribs allowing guiding in translation of the moving part could have a different shape, for example triangular, from that described above.
• the number of these grooves / ribs may be different from two.
