Description

The present invention relates to a fluid dispenser comprising a fluid reservoir for containing fluid and a dispensing member such as a pump or a valve. The reservoir includes an opening, generally in the form of a neck, defining an outer upper edge and an inner lower edge. The pump or the valve is fixed in the opening, generally bearing on the upper outer edge, possibly via a neck seal. The pump or the valve is of the manually operated type, for example with the aid of a finger. Such dispensers are frequently used in the field of perfumery, cosmetics or even pharmacy to distribute various fluid products of varying consistency.

The counterfeiting of such distributors is a major scourge, especially in the field of perfumery. In addition to outright forgery, forgery is another form of infringement of the rights of the manufacturer or the original creator. A type of forgery now common is to disassemble the dispenser to recover either the reservoir and / or the dispensing member, or the fluid, in this case the perfume. Then, the tank can be filled with another fluid that does not match that of the tank, or similarly, the real fluid can be packaged in another tank optionally with another dispensing member. In both cases, this requires the disassembly of the dispenser, and in particular the withdrawal of the pump or the valve, that is to say its separation from the reservoir.

Generally, the pump or valve is fixed on or in a neck formed by the reservoir by means of fixing means, for example in the form of a fixing ring.

The documents US 3,129,854 A , US 6,189,741 B and FR 2 756 546 A disclose dispensers having anti-manufacturing means.

The present invention thus aims to prevent, or at least to make it more difficult, the falsification of such fluid dispensers. For this purpose, an object of the invention is to destroy or render unusable the fluid contained in the tank in case of an attempt to remove the pump or the valve of the tank, in particular after removal of the fastening means. Another object of the invention is to make the pump or the valve indémontable or very difficult to dismount, even in case of withdrawal or destruction of the fastening means.

To achieve these objects, the present invention provides anti-forgery means distinct from the fastening means and secured to the dispensing member, the anti-forgery means coming into contact with the inner edge in case of attempted withdrawal. the dispensing member out of the opening, the anti-forgery means being integral with a support member engaged around the dispenser member and provided with identification means, preferably of the type RFiD. Advantageously, the reservoir comprises a collar that protrudes from a shoulder, the neck defining the opening with the inner edge formed at the junction of the neck and the shoulder inside the reservoir, the inner edge having a diameter greater than that of the opening, the neck defining an inner wall connecting the two edges together. Advantageously, the anti-forgery means comprise abutment means capable of coming into abutting contact against the inner edge, said abutment means being deployable between an insertion position in which they are insertable through the opening and a deployed position in which they extend in the tank below the inner edge so as to come into contact with said inner edge in case of withdrawal of the dispenser member out of the opening. The abutment means are not necessarily in contact with the inner edge in the deployed position. They can indeed stay at a distance, while defining an outer diameter greater than that of the opening.

A principle of the present invention is to use the abutment of abutment means against the inner edge of the reservoir to generate or generate one or more reactions that will make the dispenser more difficult to forge. The abutment means may come into pressed contact against the internal edge, in particular when the fastening means have previously been removed.

According to one embodiment, the abutment means are elastically deformable so as to return to a rest position which corresponds to the deployed position. Advantageously, the abutment means comprise an elastically deformable corolla which points, in the rest position, radially outward towards the inner edge. The elasticity of the corolla allows it to pass through elastic deformation through the restricted opening of the reservoir, so that the corolla can then deploy radially outwardly as soon as it has passed the passage of the opening. This deployment of course results in an increase in the outer diameter of the corolla which is then housed just below the inner edge, without necessarily being in contact with the latter.

According to another embodiment, the abutment means comprise an expandable material in contact with the fluid product. Thus, the expandable material can be introduced through the reservoir opening in its reduced or unexpanded form. On the other hand, as soon as it comes into contact with the fluid product, a chemical reaction will cause the material to expand or expand so as to increase its outer diameter beyond that of the opening. Expansion can also be achieved by other means, including radiation.

According to another embodiment of the invention, the anti-falsification means comprise a removable part in the event of contact with the inner edge which exceeds a predetermined threshold so that the removable part separates from the dispensing member. . Advantageously, the removable portion falls freely into the tank. Advantageously, the separation of the removable part releases a substance capable of reacting with the fluid product. Advantageously, the separation of the removable part reveals a visual indication. The removable part may be all the anti-forgery means. The removable part can even integrate other elements providing other functions. However, it is the separation of the removable part of the dispensing member which constitutes means of indication or triggering which will make it possible to remark very quickly the falsification of the distributors.

According to another aspect of the invention, the anti-forgery means block the dispensing member in the opening. In this case, the anti-forgery means prohibit withdrawal or extraction of the dispenser member from the opening, without at the same time ensuring the attachment of the dispenser member in the opening.

According to the invention, the anti-forgery means are integral with a support member engaged around the dispensing member. This support element is provided with identification means, advantageously of the RFID type. Thus, the anti-forgery means are combined with identification means in the form of a unitary piece which is advantageously engaged or fixed around the dispensing member, or alternatively fixed or locked inside the unit. the opening between the upper edge and the lower edge. Another principle of the invention is to provide an internal stop within the reservoir which is independent of the mounting or fixing of the dispensing member, so that the stop is active when one wants to remove the dispensing member of the opening. In other words, the dispensing member does not participate advantageously in the realization of the abutment under the inner edge of the reservoir. On the other hand, as soon as it is desired to remove the dispensing member from the opening, the anti-forgery means abuts against the internal edge, which either prevents the withdrawal of the dispensing member or causes some or all of the forgery means to separate from the dispensing member to generate various reactions to identify very easily the forgery of the dispenser.

The invention will be more fully described with reference to the accompanying drawings giving by way of non-limiting examples several embodiments of the invention.

In the various figures used to illustrate the present invention, the anti-forgery means according to the invention have been implemented in a conventional fluid dispenser in the fields of perfumery, cosmetics or even pharmacy. In a completely conventional manner, a dispenser comprises a reservoir 2 and a dispenser member 3.

The tank 2 comprises a tank body 21 defining a bottom (not shown) and a side wall. At its upper end, the body 21 forms a shoulder 22 which is advantageously extended by a projecting neck 23. This neck 23 defines an opening 230 through which the interior of the tank can communicate with the outside. The interior of the tank defines a useful volume for containing fluid. This useful volume can be constant or variable, depending on the nature of the body 21. Indeed, the body 21 can be made of a rigid material which leads to a constant useful volume. Alternatively, the body 21 may be made of a flexible material in the form of a flexible bag, or a deformable container, and in this case the useful volume of the reservoir is variable. In general, that the tank body 21 is rigid or deformable, the neck 23 is rigid, that is to say made of a dimensionally stable material. In the embodiment shown in the figures, the tank 2 can be made of glass, rigid or substantially rigid plastic or metal. Other materials are not excluded, however. The neck 23 comprises an upper annular edge 25, an inner wall 27 and an inner lower edge 26 which is located substantially at the junction of the neck with the shoulder 22. This inner edge 26 is already located inside the volume useful 20 defined by the tank. The inner wall 27 connects the upper edge 25 to the inner edge 26. The inner wall 27 has a generally cylindrical shape. The neck 23 also defines an external reinforcement 24 which is in the form of a peripheral bead which protrudes outwards and which thus defines a recess oriented downwards. This is a quite conventional design for a conventional tank in the field of perfumery, cosmetics or pharmacy.

The dispensing member 3 comprises dispensing means 30 which may be in the form of a pump, a valve or any closure system. The dispensing means 30 may be manual, electric or electronic. It can be used various technologies such as piezoelectric or ultrasonic. In the figures, the distribution means 30 are shown very schematically, and it may be a manual pump. This pump 30 comprises a pump body 300 of substantially cylindrical or stepped shape. At its upper end, the body 300 can form a retaining flange 302, while at its lower end, the body 300 can be extended by a dip tube 301 which extends inside the reservoir 2. Whatever is the nature of the dispensing means, they must allow the removal of fluid from the reservoir and the distribution of this fluid taken outwardly so that the user can apply it on an application surface or distribute it in the air.

The pump 30 is provided with various associated members, such as for example a pusher 31 on which can be pressed with one or more finger (s) to actuate the pump 30, and fixing means for fixing the pump 30 on the tank. These fixing means here comprise several parts, namely a cup 32, a fixing ring 33 and a trim band 34. The flange 302 of the pump body 300 is fixedly engaged in a housing formed by the cup 32. The cup 32 on its outer periphery is engaged within the ring 33. This ring 33 comprises one or more attachment profile (s) 331 intended (s) to cooperate with the neck 23 of the tank for fixing on the neck of the tank. Finally, the band 34 comes to lock the ring 33 engaged around the neck. These are quite conventional fastening means, and other fastening means can be used without departing from the scope of the invention. For example, fastening means can be used to screw or crimp. The purpose of the fastening means is to achieve a solid and sealed attachment of the dispensing means 30 on the reservoir. For this purpose, to guarantee the seal at the neck, there is provided a neck seal 35 interposed between the cup 32 and the upper edge 25 of the neck 23. When the dispensing member 3 is mounted on the reservoir as shown in the various figures, the pump body 300 extends inside the neck 23 in the opening 230. The attachment profiles 331 of the ring 33 are engaged below the reinforcement 24 formed on the outside of the neck 23. The ferrule 34 extends around the ring and is advantageously supported on the shoulder 22. The neck seal 35 is compressed between the cup 32 and the upper edge 25. The dip tube 301 extends inside the tank until 'near its bottom. By pressing on the pusher 31, the dispensing means 30 are actuated, which has the effect of dispensing fluid through a dispensing orifice (not shown), but which is very often provided in the pusher 31. All this mechanism is quite conventional for a fluid dispenser in the field of perfumery, cosmetics or pharmacy.

According to the invention, the dispenser is provided with anti-forgery or inviolability means which have been designated in the figures by the reference numeral 1, although they are in various embodiments. Moreover, in these various embodiments, elements or parts that are identical or that fulfill the same function have been designated by the same reference numerals, although they may differ in their shape.

We will first refer to the figure 1 to explain in detail a first embodiment of anti-forgery means which does not form part of the invention. The anti-falsification means 1 comprise a generally cylindrical body defining a lower part 10 and an upper part 12. The upper part 12 serves as a fixing sleeve on the body 300 of the distribution means 30. As for the lower part 10, it serves as an extension and base sleeve to abutment means 11 which are here in the form of a frustoconical corolla whose free annular end 111 points outwardly and upwardly towards the shoulder 22, and more specifically the inner edge 26. Alternatively, the corolla 11 may be continuous or formed by a plurality of tabs (or sectors) elastically deformable which are oriented in the same way as the corolla. It may be noted that the lower part 10 forms an inward recess 105 with respect to the outer wall of the fixing sleeve 12. This inward recess 105 makes it possible to provide a free space for the stop means 11 when they are forced elastically inwards so as to press the corolla or the lugs against the portion 10. This inward recess 105 is particularly useful for accommodating the abutment means 11 when the anti-forgery means 1 are inserted into the tank 2 through the opening 230. Indeed, the opening 230 defines a restricted passage relative to the useful volume 20. It is still possible to insert the anti-forgery means 1 through this opening 230 because the abutment means 11 can be deformed elastically inwards in the recess 105. As soon as the anti-forgery means have reached the end position as shown in FIG. figure 1 , the abutment means 11 can again return to their initial position of rest in which they point with their free end towards the inner edge 26. It is not essential that the free end 111 is in contact with the edge 26. On the contrary, there may be a small gap between the end 111 and the edge 26.

The anti-falsification means 1 can be maintained on the pump body 300 using various techniques, such as gluing, welding, or snapping into force. The fixing of the anti-forgery means 1 on the pump body 300 may be definitive or defeasable. In other words, it is possible to secure the anti-forgery means 1 and the dispensing means 30 so as to form an indefinable unitary piece. Alternatively, it is possible to separate the anti-forgery means 1 or at least a part thereof from the distribution means 30.

When a falsifier wants to disassemble the dispenser, it usually starts by removing the band 34 to access the ring 33. By removing the ring, the dispensing means (pump or valve) are also removed. This has the effect of moving the dispensing means 30 inside the neck 23 of the reservoir. It is then easily understood that a slight upward displacement of the distribution means has the effect of putting the free end 111 of the means of stop 11 bearing against the inner edge 26 of the tank. If the anti-forgery means 1 are permanently connected to the distribution means 30, the abutment of the abutment means against the edge 26 has the effect of preventing the extraction or withdrawal of the dispensing means 30 As a variant, when the anti-forgery means, or part of them, are separable from the dispensing means 30, the extraction of the dispensing means will have the effect of separating the anti-forgery means. , or a part thereof, so that the anti-forgery means, or a part thereof, will remain in place in the neck 23, or fall freely inside the tank. Even in case of significant deformation of the corolla, which can lead to a curl of the corolla with the free end going down, the corolla still fulfills its role of stop means preventing the extraction of the means of anti-forgery out of the tank. In any case, the anti-falsification means 1, thanks to their stop means, can not be extracted from the tank. In the mode of carrying out the figure 1 , the anti-forgery means are made integrally with the upper part 12 integrally connected to the lower part 10. These anti-forgery means 1 are either permanently attached to the body 300 of the pump 30, or separable in their entirety of the pump body 300. In case of separation, the anti-falsification means 1 will fall freely inside the tank, which will then make it unsuitable for further use. Indeed, the abutment means, because of their size, prohibit, or at least complicate, the extraction of anti-forgery means out of the tank through the neck. The anti-falsification means freely floating in the tank is a clear visual indication that the dispenser has been forced.

The means of anti-falsification of the figure 2 constitute an embodiment of the invention. The anti-falsification means 1 also comprise an upper part 12 providing a fixing sleeve on the body of the dispensing means 30 and a lower part 10 serving as a base for abutment means 11 intended to abut against the inner edge. 23 in case of an attempt to extract the organs of the distribution means 30. The abutment means 11 are made identically or similarly to those of the figure 1 , that is to say with a peripheral corolla or tabs which point outwards and upwards towards the edge 26. The free ends of the abutment means can be separated from the edge 26 by a small gap. However, the ends of the abutment means may also come into contact with the edge 26. In this second embodiment, the lower part 10 is separable from the upper part 12 which is permanently attached to the body of the distribution means 30 and / or 23. It may be noted in particular that figure 2 that the upper part 12 is in tight contact around the body of the distribution means 30: the attachment can be carried out by any technique, such as for example welding, gluing or snapping in force. In addition, the upper portion 12 comprises a support flange 123 which bears on the neck 23 near its upper edge 25. More specifically, the neck forms an inlet chamfer which extends annularly on the periphery In this embodiment, it is quite possible that the upper part 12 is not permanently fixed to the body of the distribution means 30 and that the retention in place of the upper part 12 is entirely achieved by the support flange 123. Still according to this embodiment, the upper part 12 serves as a support element for an identification unit which comprises for example an electronic chip 13 and an antenna 14 which is wound around the body of the means. of distribution. These means of identification may for example use RFID technology (radio frequency identification). This identification unit can remotely deliver distributor information. The chip 13 allows the storage of information while the antenna 14 is used for receiving and transmitting signals that also allow to energize the identification unit.

As mentioned above, the portion 12 is separable from the portion 10 at a junction that can be made by snapping or snapping into force. The upper part 12 can form latching means 100, in the form of a crown or discrete studs, which are engaged in a housing 101, not definitively or defeasable. Alternatively, the junction that can be made for example in the form of a brittle material bridge or a weak weld. The housing 101, which serves as a latching or plugging housing, also contains a substance 102 which is for example likely to react with the fluid stored inside the tank. It is also possible to envisage a substance 102 that reacts with any radiation such as daylight. The housing 101 is open upwards, and after separation of the portion 10 of the portion 12, this housing is accessible, and the substance 102 can then come into contact with the fluid. As in the previous embodiment, the lower part 10 serves as a base for the abutment means 11 which point towards the edge 26. The latching means 100, (and more generally the junction between the parts 10 and 12) serve here means for closing the housing 101 which contains the substance 102. The anti-forgery means also form a peripheral clearance for housing the abutment means 11 during passage through the neck 23. Advantageously, this release s' extends on both the upper part and the lower part 10. On the upper part 12, the clearance can be provided with an inscription or an indication 125 which will be visible once the part 10 is separated from the part 12 Indeed, when a falsifier wants to remove the distribution means 30, it will exert an upward pull which has the effect of bringing the free end of the abutment means 11 in contact pressed against the edge 26. By exerting a force greater than a predetermined threshold, the portion 10 will separate from the portion 12 and fall freely inside the tank. By separating, the abutment means 11 will reveal or unmask the lower part of the part 12, more particularly at the clearance so that the inscription or the indication 125 will then be visible through the reservoir, when the latter is transparent. Thus, even in the case of a simple attempt to extract the dispensing means, the lower part 10 will separate from the upper part 12 and fall inside the tank. The reactive material 102 will then "pollute" the fluid product by denaturing it in various ways. For example, it can be imagined that the material 102 colors the fluid, modifies its odor, changes its viscosity, etc. Anyway he is necessary that the portion 12 is integral with the distribution means 30, because it will serve as a traction transmission element to the lower part 10.

We will now refer to Figures 3a and 3b which show a third embodiment in which the anti-falsification means 1 also comprise an upper portion 12 serving as a fixing sleeve to the pump body and a lower portion 10 which will make the abutment against the edge 26 in case of attempt extraction or extraction of the dispensing means out of the neck of the tank. In this embodiment, the upper part 12 is also provided with an identification unit which may be identical to that of the figure 2 . The upper portion 12 is permanently attached to the body of the dispensing means by any suitable technique. The upper part 12 can also form a support flange identical to that of the figure 2 . However, this feature is optional. According to the invention, the upper part 12 is provided with anchoring means 124 which may be in the form of a continuous annular bead or discrete studs distributed peripherally. These anchoring means 124 are located at the lower end of the upper portion 12. The lower portion 10 is here made from an expandable or expandable material which is for example overmolded on the anchoring means 124. A initial state, the lower part 10 has an outer diameter which is substantially equal to that of the upper part 12, so that the anti-forgery means can be inserted through the opening of the tank without friction at all or without exaggerated friction. According to the invention, the constituent material of the lower part 10 is able to react with the fluid product in the reservoir so as to expand or expand, which has the effect of increasing its external diameter, as can be see him on the figure 3b . It is also possible to provide a material that reacts with radiation or with heat. In all cases, the expansion of the lower portion 10 has the effect of increasing the size and thus create a stop profile 11 which is located near the inner edge 26. This profile 11 will serve as abutment means, as well as the corolla or the legs of the first and second embodiments. When a falsifier wants to withdraw the means of distribution, the abutment profile 11 will come into contact pressed against the edge 26. Two situations are then possible. First, the lower part 10 is fixedly connected to the upper part 12, and in this case it is not possible to remove the distribution means. Second, the lower part 10 is separable from the upper part 12 by breaking anchoring means 124 and in this case it is possible to remove the distribution means, but the lower part 10 will then fall freely inside the tank . Again, the anti-forgery means comprise abutment means capable of coming into abutting contact against the inner edge 26 of the neck of the reservoir.

Referring now to the figure 4 , we see an alternative embodiment that can be considered as a hybrid between the first and second embodiments. Indeed, the anti-falsification means 1 are here made integrally, that is to say, with the upper part made integrally with the lower part. The lower part serves as support for the abutment means which point towards the lower edge of the neck. The anti-forgery means 1 are devoid of support flange adapted to bear on the neck. The anti-forgery means 1 may be permanently connected to the dispensing means 30 so that they permanently block the dispensing means 30 in the neck. In a variant, the anti-falsification means 1 can be separable from the dispensing means 30 so that an attempt to extract or completely extract the dispensing means 30 has the effect of separating the anti-tampering means. falsification 1 which will then fall inside the tank.

On the figure 5 which represents an embodiment which does not form part of the present invention, one sees anti-falsification means 1 which are devoid of upper part. The anti-falsification means are summarized here in the lower part 10 which is directly fixed permanently or detachably to the body of the distribution means 30. Alternatively, it is conceivable to realize the anti-forgery means in a monobloc manner with the body of the means of distribution. In case of attempted withdrawal, the body will be damaged, or even broken into several fragments.

In the last embodiment of the figure 6 which constitutes an alternative embodiment of the third embodiment of the Figures 3a and 3b , the lower part 10 of the anti-forgery means 1 are also made of an expandable or expandable material. However, the lower part once expanded comes into contact against the collar at its lower edge. This has the effect of stably fixing the anti-falsification means 1 inside the neck. This is all the more feasible that the upper portion 12 comprises a bearing flange 125 resting on the input chamfer of the neck. By definitively fixing the anti-forgery means to the dispensing means, the stable fastening of the dispensing means 30 inside the neck can be achieved solely by means of anti-forgery means. In this case, we can do without the cup and the fixing ring and the hoop. One can even imagine distribution means 30, such as a pump or a valve whose body is provided in the lower part of a ring of expandable material which will achieve the final fixing of the pump or the valve in the neck of the tank. In this case, the anti-forgery means fulfill a real definitive and indémontable fixing function of the pump.

The anti-falsification means, in all the embodiments, may be considered as comprising abutment means able to come into pressed contact against the internal edge of the neck of the reservoir, these abutment means being fixed on a support element which engages either with the body of the dispensing means, or with the neck, or both at once. In addition, this support member may be made integrally or divisible into two parts, one remaining attached to the body of the dispensing means or the neck and the other falling freely in the tank.

A principle of the invention is to introduce an element into the tank together with the dispensing member (pump, valve, cap, etc.), this element can no longer be extracted from the tank, even in case of withdrawal or attempt to withdraw the distribution organ. Of course, withdrawal or attempted withdrawal can only be done in most cases after previously removed or destroyed the fastening means which firmly held the dispensing member on or in the neck of the reservoir, these fastening means being generally distinct anti-forgery means.
