• the user can directly access the contents of the tank, for example to collect the remaining fluid, especially when it is a cream.
• the disassembly capacity of the dispenser can also be used for recycling purposes.
• this disassembly ability also allows a malicious user to alter or replace the fluid product initially contained in the tank, then reassemble the fastening system to reconstitute the fluid dispenser.
• the dismantling of the fastening system creates insecurity as to the authenticity of the distributor's contents.
• the present invention aims to overcome this drawback of the prior art related to removable fluid dispensers.
• the present invention provides that the skirt further comprises at least one abutment lug intended to come into axial abutment on the neck, when attempting to raise the fixing ring on the neck after a first disassembly of the distributor. .
• the stop tab will prevent reassembly of the dispenser by interposing between the fastening lugs and the neck of the tank. By abutting on the neck, the stop tab will prevent the engagement of the fastening tabs around the neck.

• This fixing system comprises a fixing ring 1 associated with a rigid hoop 2 which is intended to engage with radial clamping around the fixing ring 1, as will be seen below.
• the fixing ring 1 can be made by injection molding of suitable plastic material.
• the rigid hoop 2 it can also be made of plastic, but preferably it is made of metal, so as to confer an aesthetic appeal to the distributor.
• the fastening system thus constituted by the ring 1 and the hoop 2 serves to fix a dispensing member 3, such as a pump or a valve, on a tank neck 41 so as to constitute a fluid dispenser .
• the fastening system has a dual function, namely a fastening function, but also a sealing function.
• the fluid product stored in the reservoir can be extracted only through the dispensing member.
• the fixing ring 1 comprises receiving means 1 1 for receiving the dispensing member 3.
• the receiving means 1 1 can for example be in the form of an annular latching housing in which is received a protruding flange formed by the dispensing member.
• the ring 1 also forms an axial opening 12 which extends inside the fastening means 1 1, and which serves for the passage of the actuating rod of the dispensing member, which is movable axially back and forth.
• the ring forms an annular plate 13 which is positioned on the annular edge of the neck of the tank, with possible interposition of an annular neck seal.
• the fixing ring 1 1 externally forms a skirt 14 which is made discontinuously in its lower part, thus forming fastening lugs 15 and abutment lugs 16 separated by slots 17 and interspersed alternately.
• a fixing lug 15 is adjacent to two stop lugs 16, and vice versa.
• the fixing ring 1, in this particular embodiment comprises three fastening lugs 15 and three abutment lugs 16.
• the dispensing member 3 extends inside the the skirt 14, as can be seen in Figures 2 and 3.
• the dispensing member 3 forms a body 31 whose upper end is engaged in the receiving means 1 January. At its lower end, the body 11 forms a fluid inlet 32 provided with a dip tube 33.
• the fixing lugs 15 extend freely downwards and form inwardly one or more profile (s) 151 intended (s) to come into engagement with the neck of the reservoir, as will be seen below.
• the profiles 151 may be preformed so as to fit in a complementary manner to the neck of the reservoir. Alternatively, the profiles 151 are intended to be deformed against the neck of the reservoir so as to print a negative impression in these profiles.
• These profiles 151 may for example be used for screwing and / or unscrewing on a threaded neck. They can also be used to snap or snap on a suitable collar.
• the fastening technique of the flaps on the neck is not critical to the present invention, since the fastener ring can be removed from the neck of the tank without destroying the fastening system.
• the fixing lugs 15 extend with a slight shrinkage with respect to the continuous upper part of the skirt 14. However, when the fastening lugs 15 are engaged on a tank neck, these are deformed outwards by flaring, so as to be pushed inward against the neck by the rigid band 2.
• the stop lugs 16 also extend freely downwards in a substantially similar manner to the fixing lugs 15.
• the particular form of the abutment lugs 16 is, however, very different from that of the attachment lugs 15. Indeed, the abutment lugs 16 extend, before definitive engagement of the hoop 2 around the ring, radially outwardly relative to the remainder of the skirt 14, and in particular with respect to the fixing lugs 15.
• the rigid hoop 2 is pre-engaged on the fixing ring 1, with the lugs 15 and 16 which are still projecting axially downwards.
• the stop lugs 16 have an outer diameter which is greater than that of the hoop 2.
• the stop lugs 16 comprise an upper section 161 having an upper end 162 connected to the remainder of the skirt 14, and a lower end 163, which is connected to a lower section 164 defining a lower free end 166.
• the upper end 165 of the lower section 164 is connected to the lower end 163 of the upper section 161, as can be seen in FIG. see very clearly in Figure 1. It may also be noted that the wall thickness of the upper section 161 at its upper end
• the inclined slope formed by the outer surface of the upper section 161 will also serve as a cam surface for the lower edge of the hoop 2 when engaged around the skirt 14.
• the stop lugs 16 will be progressively deformed inwardly as the hoop 2 engages on the upper sections 161 of the three legs 16.
• the rigid hoop 2 is essentially circular cylindrical at its main body 21, but also comprises an upper reentrant flap 22.
• FIG. 6 shows the fixing ring 1 after deformation by the rigid hoop 2.
• the free lower end 166 of the abutment lugs 16 are effectively in contact with the neck 41, with a non-definitive elastic deformation, the only final deformation being that performed at the upper end 162.
• the dispenser is then in its final mounted state, ready to be used.
• the dispenser is removable, so that the user can remove the fastening system of the neck of the tank.
• This disassembly operation can be performed by unscrewing, as in the present case, but it can also be carried out by any other appropriate action allowing disassembly without destruction of the fastening system.
• FIG. 7 shows the distributor in the disassembled state. It may be noted that the free end 166 of the abutment lug 16 abuts on the annular edge 43 of the neck of the reservoir. Thus, it is no longer possible to raise the fastening system on the neck, because the abutment lugs 16 prevent the engagement of the fastening lugs 15 around the neck. Because of the inclined inward and downward orientation of the lower section 164, even if this fastening system is strongly supported, this will tend to further engage or deform the abutment lugs 16 to inside, and even to penetrate slightly into the neck of the tank.
• the stop tabs 16 prevent the reassembly of the dispenser, without preventing either assembly or disassembly. This is made possible by a combined deformation of the abutment lugs 16, namely a final deformation by pivoting around their upper ends by the engagement of the hoop 2, and a reversible elastic deformation by elastic support of their free ends 166 against the collar.
