• the trim ring 5 ' which is generally cylindrical, is not yet engaged around the skirt 33.
• the fastening system F is in the final mounting position on the neck 1 1.
• the security ring 4 ' is housed under the shoulder 13, the skirt 33 is engaged with the thread 12 and the hoop 5' is in contact with the peripheral region 15 of the neck 1 January.
• the dispenser can be used normally in this configuration by pressing the pusher (not shown) mounted on the actuating rod 24 of the dispensing member 2.
• the fastening system F has already been unscrewed from the threaded neck so as to disengage the security ring 4 ', which nevertheless remains engaged inside the skirt 33 by the abutment between the fastening means 45 and the hooking profile 35.
• the abutment element 41 abuts under the shoulder 13.
• the user has already begun tearing the tear-off strip 48 by pulling it at the level of the tongue. This has the effect of separating the strippable strip 48 from the collar 43 which remains engaged within the skirt 33 of the fixing ring.
• the stop element 41 can be released from below the shoulder 13, and thus remove the entire system of as shown in FIG. 13.
• the collar 43 always remains engaged inside the ring 3. Since the tear-off strip 48 does not extend over the entire periphery of the ring 48, it remains secured to the rest of the security ring 4 '.
• the user must proceed with two successive dismantling steps, namely a first step of unscrewing, followed by a second step of pulling and tearing the strip 48.
• a first step of unscrewing By pulling strongly on the strip 48, it is possible to remove the entire security ring 4 'of the Inside the ring 3.
• a second step of pulling and tearing the strip 48 By pulling strongly on the strip 48, it is possible to remove the entire security ring 4 'of the Inside the ring 3.
• the second step of pulling and pulling is intended to complicate the procedure of dismantling the fastening system to dissuade potential malicious users or wanting to disassemble the system inadvertently .
• the presence of a gripping tongue 49 is sufficient to make it clear to the user that it must be pulled to obtain the unlocking or unlocking of the security ring 4 '.
• the axial displacement of the ring 4 'inside the fixing ring 3 takes place over an axial distance which is greater than or equal to the axial unscrewing stroke of the fixing ring 3.
• This second embodiment has the advantage of being able to use a perfectly cylindrical conventional trim ring, without using an inner sleeve 52, as is the case in the first embodiment.
• the disadvantage of this second embodiment is that the security ring 4 'is partially destroyed after use, while the security ring 4 of the first embodiment is only momentarily deformed. It is however possible to implement the crown 4 of the first embodiment in the second embodiment instead of the crown 4 ', and vice versa.
• the conventional unscrewing of the fastening system is associated with an additional voluntary gesture that requires the user a certain degree and moment of reflection. Indeed, he must think to understand how it must act on the security ring to be able to disengage or unblock its grip or stop with the neck of the tank.
• the actuating zones 42 and the tear-off strip 48 constitute means for unlocking the safety rings 4, 4 'which facilitate the disengagement of the ring from below the shoulder.
• deblocking is optional in the present invention: the user could himself deteriorate or cut the security ring to release it from the neck.
