Description

Fixing system and distributor of fluid product that uses said system

The present invention relates to a fixing system for fixing a distribution organ, such as a pump or a valve, on the neck of a container to constitute a fluid product distributor. The distribution organ is manually operable by the user with the help of one or more fingers, so as to distribute fluid product in dosed form or not. This type of portable manual distributor is frequently used in the fields of perfumery, cosmetics or pharmacy.

In the prior art, fixing systems already exist comprising a fixing ring associated with a rigid collar hooked around the fixing ring. The ring generally comprises a skirt intended to be hooked around the neck, this skirt comprises fixing legs intended to be fixedly coupled with an appropriate profile formed by the neck. For example, a threading can be provided at the level of the external wall of the neck, and the fixing legs are coupled by means of threading with the neck. You can also imagine other types of neck profile that allow, for example, a fastener or a hitch. The rigid clamp is often used to push the fixing legs against the appropriate neck profile. Document FR 2 932 783 A1 shows a fixing system according to the preamble of claim 1.

Within the framework of the present invention, the fluid product distributor is removable: the fixing system can be removed from the neck by a suitable action, such as traction, unscrewing, rotation or a combined action. Thus, the user can directly access the contents of the container, for example to receive the rest of the fluid product, specifically when it is a cream. The dismantling capacity of the distributor can also be put into use in a recycling target.

However, this ability to disassemble also allows a malicious user to alter or replace the fluid product initially contained in the container, and reassemble the fixing system to reconstitute the fluid product distributor. Due to this, the disassembly of the fixing system causes an uncertainty regarding the authenticity of the distributor's content.

The present invention aims to remedy this drawback of the prior art related to removable fluid product distributors.

To do this, the present invention provides that the skirt also comprises at least one stop leg intended to axially bump on the neck, when trying to reassemble the fixing ring on the neck after a first disassembly of the distributor. In other words, the stop leg will prevent reassembly of the distributor by interposing between the fixing legs and the neck of the container. When bumping on the neck, the stop leg prevents the attachment of the fixing legs around the neck.

Advantageously, the stop leg, after disassembly, is projected radially inwards with respect to the fixing feet, so as to bump onto the neck of the container in case of an attempt to reassemble it.

Of course, it is not necessary that the stop leg prevents the initial assembly of the distributor. To do this, the present invention provides that the stopper leg is projected radially outwardly before the collar is engaged around the skirt. During assembly, the stop leg deforms radially inwards through the neck, advantageously by rotation.

According to a practical embodiment, the stop leg comprises an upper section having an upper end attached to the rest of the ring and a lower end, and a lower section having an upper end attached to the lower end of the upper section, the two sections extend with respect to each other at an angle, the upper section widens outward before the collar hooks around the skirt. Advantageously, the stopper leg is permanently deformed inwards by the collar at the level of the upper end of the upper section attached to the rest of the ring. Preferably, the upper section extends axially and the lower section extends inwardly after the collar hitch around the skirt. Thus, the butt leg experiences at the same time a definitive deformation by deformation or rotation at the level where it joins the rest of the ring and a soft elastic reversible deformation on its length by support on the neck of the container. In this way, the stop leg is held in its turned position after disassembly, but it will relax elastically in order to regain its initial shape as soon as when it is no longer bent against the collar. This combination of definitive and reversible deformation allows the stopper leg to not obstruct the distributor assembly, allow its disassembly and prevent reassembly after disassembly. The stop leg is prevented from returning to its original orientation by the rigid clamp that surrounds it. However, it will recover its original configuration, the removal of the neck, with a modified orientation.

The invention also defines a fluid product distributor comprising a fluid product container comprising a neck, a distribution organ, such as a pump and a fixing system as defined.

previously, where the collar definitely rotates the stop leg inwards and elastically attracts it against the neck of the container. Advantageously, the neck comprises an external thread, the fixing legs are coupled to the external thread of the neck, the collar pushes the fixing legs against the neck.

The spirit of the present invention resides in the fact of using one or more stop legs that does not prevent assembly or disassembly, but prevent reassembly of the distributor. For this, the orientation of the stop legs must be modified so that it is in the path between the fixing legs and the neck when it is desired to reassemble the distributor. The rigid clamp is advantageously used to modify the orientation of the butt legs! as to deform them elastically so that they can relax elastically by removing them from the neck that is in the portion between the fixing legs and the collar.

The invention will now be more fully described with reference to the accompanying drawings by offering non-limiting examples a way of carrying out the invention.

First, reference is made to Figures 1 to 3 to describe in detail a non-limiting embodiment of a system for fixing the invention. This fixing system comprises a fixing ring 1 associated with a rigid collar 2 which is intended to engage radially around the fixing ring 1, as will be seen later. The fixing ring 1 can be manufactured by molded injection of an appropriate plastic material. With respect to the rigid clamp 2, it can also be made of plastic material, but preferably it is made of metal, so as to confer aesthetic appeal to the distributor. The fixing system formed in this way by the ring 1 and the collar 2 serves to fix a distribution organ 3, such as a pump or a valve, on the neck of a container 41 so as to constitute a product distributor fluid. The fixing system has a double function, that is, a fixing function, but also a sealing function. Thus, the fluid product stored in the container can only be extracted through the distribution organ.

The fixing ring 1 comprises receiving means 11 for receiving the distribution organ 3. The receiving means 11 can be presented, for example, in the form of an annular holding housing where a protruding collar formed by the receiver is received. distribution organ. The ring 1 also forms an axial opening 12 which extends inwardly from the fixing means 11, and which serve the passage of the drive rod of the distribution organ, which is axially movable back and forth. Outside the receiving means 11, the ring forms an annular plate 13 which is positioned on the annular edge of the neck of the container, with the possible interposition of an annular neck seal. Finally, the fixing ring 11 forms an outside skirt 14 which is carried out discontinuously in its lower part, thus forming the fixing legs 15 and stop legs 16 separated by grooves 17 and interposed alternately. A fixing leg 15 is adjacent to two stop legs 16, and vice versa. As can be seen in Figure 3, the fixing ring 1, in that particular embodiment, comprises three fixing legs 15 and three stop legs 16. The distribution organ 3 extends into the skirt 14, as is You can see in Figures 2 and 3. The distribution organ 3 forms a body 31 whose upper end is engaged in the receiving means 11. At its lower end, the body 11 forms a fluid product inlet 32 provided with a tube of embolus 33.

The fixing legs 15 extend freely downwards and internally form one or more profiles 151 intended to engage with the neck of the container, as will be seen later. Profiles 151 can be preformed so as to adapt in a complementary manner to the neck of the container. In variant, the profiles 151 are intended to deform against the neck of the container so as to print a negative print on these profiles. These profiles 151 can serve, for example, to screwing and / or unscrewing on a threaded neck. They can also be used for fastening or hooking on a suitable neck. The technique of fixing the legs 15 on the neck is not critical for the present invention, insofar as the fixing ring can be removed from the neck of the container without destroying the fixing system. The fixing legs 15 extend with a slight retraction with respect to the continuous upper part of the skirt 14. However, when one engages the fixing legs 15 on the neck of a container, they deform outwardly widening, so that be pushed in against the neck by the rigid clamp 2.

The stop legs 16 also extend freely downwards substantially similar to the fixing legs 15. The particular shape of the stop legs 16 is however very different from that of the fixing legs 15. In fact, the legs butt 16 extend, before the definitive engagement of the collar 2 around the ring, radially outward in relation to the rest of the skirt 14, and specifically in relation to the fixing legs 15. As can be seen in figure 2, the clamp Rigid 2 is pre-engaged on the fixing ring 1, with the legs 15 and 16 still protruding axially downwards. It should be noted that the stop legs 16 have an external diameter that is greater than that of the collar 2. More precisely, the stop legs 16 comprise an upper section 161 having an upper end 162 attached to the rest of the skirt 14, as! as a lower end 163, which joins a lower section 164 defining a free lower end 166. The upper end 165 of the lower section 164 is attached to the lower end 163 of the upper section 161, as can be seen very clearly in Figure 1. It should also be noted that the thickness of the wall of the upper section 161 at the level of its upper end 162 is reduced with respect to the rest of the stop leg 16. This reduced wall thickness defines an area of weakness that it allows a deformation of the leg by rotation at the level of the upper end 162, without significantly deforming the rest of the leg. Thus, it will be readily understood that the engagement of the collar 2 around the legs 15 and 16 will lead to the inward movement of the stopper legs 16 by turning around the upper end 162. It should be noted that the upper section 161 extends inclined towards outside and down, while the lower section 164 is substantially or perfectly cylindrical. Thus, an angle is formed between the upper section 161 and the lower section 164, as can be clearly seen in Figures 1 and 2. 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 collar 2 when hooked around the skirt 14. Thus, the stop legs 16 gradually deform inward as the collar 2 engages on the upper sections 161 of the three legs 16.

As can be seen in Figure 2, the rigid clamp 2 is substantially circular cylindrical at the level of its main body 21, but also comprises an inwardly leading flange 22.

Referring now to Figure 4, and observes the fixing system of Figures 2 and 3 hooked on a neck 41 of a container 4. This neck 41 is externally provided with a thread 42 that cooperates with the profiles 151 of the legs of fixing 15. In Figure 4, the assembly is not yet final: only the legs 15 and 16 are hooked around the threaded neck 41, but the rigid clamp 2 is not yet fully engaged around the ring. By exerting sufficient force on the upper end of the collar 2, it is moved downwards by pushing the fixing legs 15 strongly against the threaded neck of the container and deforming it by turning the stopper legs 16 inwards. The profiles 151 are deformed plastically against the thread 42 of the neck, while the stop legs 16 are simply pushed or elastically drawn against that neck.

With reference to Figures 5 and 6, it can be seen that the upper section 161 of the stop leg 16 now extends in the extension of the skirt 14, while the lower section 164 is oriented inwards and downwards. This is still visible in Figure 6 showing the fixing ring 1 before deformation by the rigid clamp 2. The free lower end 166 of the stop legs 16 are effectively in contact with the neck 41, with an elastic deformation not definitive, the definitive deformation puncture is that which is carried out at the level of the upper end 162. The distributor is then in its final assembled state, ready to be used.

However, in the context of the invention, the distributor is removable, so that the user can remove the fastening system from the neck of the container. This disassembly operation can be carried out by unscrewing, as in this case, but it can also be performed by any other action suitable for disassembly without destroying the fastening system.

By removing the fixing ring from the neck of the container, the stop legs 16 retain their orientation imposed by the rigid clamp 2, and their free ends 166 are released from the neck, and can be elastically relaxed to extend radially further inward. Figure 7 represents the distributor in disassembled state. It should be noted that the free end 166 of the stop leg 16 bumps over the annular edge 43 of the neck of the container. Thus, it is no longer possible to reassemble the fixing system on the neck, because the stop legs 16 prevent the attachment of the fixing legs 15 around the neck. Due to the inward and downward orientation of the lower section 164, even if it relies heavily on that fixing system, it will tend to engage or further deform the stop legs 16 inward, and even to slightly penetrate the bowl neck

Thanks to the invention, the stop legs 16 prevent the distributor from being reassembled, without preventing assembly or disassembly. This is possible by a combined deformation of the stop legs 16, namely a definitive deformation by turning around its upper ends by the hitch of the collar 2, and a reversible elastic deformation by the elastic support of its free ends 166 against the neck .
