Description

BACKGROUND OF THE INVENTION The invention relates to a system for manufacturing a cosmetic product, as well as to a system for manufacturing a cosmetic product and a method for producing a cosmetic product from such a manufacturing system. method of manufacture, by the final consumer, of a cosmetic product directly consumable by the final consumer, from such a manufacturing system. BACKGROUND OF THE INVENTION The invention relates to a system for manufacturing a cosmetic product, comprising at least two capsules, as well as a method of manufacturing, by the final consumer, of a cosmetic product directly consumable by the final consumer and allows the manufacture of a limited dose of cosmetic product whose composition is then easily customizable based on the starting ingredients. To use a separate cosmetic product for the next application, the end consumer only needs to change one and / or the other capsule of the manufacturing system. In addition, the cosmetic product obtained is immediately consumable by the end consumer, which on the one hand allows a better freshness of the cosmetic product and on the other hand exempts most or all of the usual preservatives used. The invention relates to a system for manufacturing a cosmetic product, as well as to a method for manufacturing, by the final consumer, a cosmetic product which can be consumed directly by the final consumer, from such a manufacturing system, without the use of a machine 3031092 2 responsible for carrying out the transfer from one capsule to another. This transfer from one capsule to the other of the mixture is carried out by the final consumer of the cosmetic product, by simple hand pressure. The pressure of a hand is substantially lower than the pressure exerted by the elements of such a machine. The manufacture of the cosmetic product, not requiring a machine, that is to say no active device using a power source, but only the manual energy of the final consumer, is then much simpler and less expensive. According to a first prior art, for example described in patent US4458811, it is known a capsule with two compartments for manufacturing a cosmetic product by mixing the contents of one compartment in the other compartment. A communication between the two compartments allows mixing. The setting in communication once carried out, the passage between the compartments is very broad. The mixture is made by shaking the entire capsule. The use of a two compartment capsule has the disadvantage of imposing on the end consumer the pair of phases to be mixed as soon as the two compartment capsule is purchased. To provide for all the interesting combinations of phases to mix a large number of two-compartment capsules must be manufactured and offered for sale. According to a second prior art, for example described in the patent DE3724921, it is known a capsule with three compartments for manufacturing a cosmetic product by mixing the contents of two compartments in a third compartment acting as a mixing chamber. Communicating the different compartments allows mixing. The use of a two compartment capsule has the disadvantage of imposing on the end consumer the pair of phases to be mixed as soon as the two compartment capsule is purchased. To provide for all the interesting combinations of phases to mix a large number of two-compartment capsules must be manufactured and offered for sale.

SUMMARY OF THE INVENTION The object of the present invention is to provide a manufacturing system at least partially overcoming the aforementioned drawbacks.

More particularly, the invention aims to provide a manufacturing system which, while maintaining the great simplicity of the absence of use of a machine for effecting phase mixing, however offers a great wealth of phase combinations, and this, without requiring the manufacture and offer for sale of a large number of capsules two compartments. For this, the invention provides a manufacturing system comprising two capsules completely separated from one another, and which will be assembled together manually to achieve the mixing of the two phases.

The provision of capsules separated from each other, each comprising one of the phases to be mixed, greatly reduces the number of combinations to be manufactured. Indeed, if for example ten types of first phase must be able to mix with ten types of second phase, it suffices to manufacture twenty different capsules, each containing one of the types of first phase or one of the types of second phase. , whereas if the two phases had been integrated in the two compartments of a capsule, it would have been necessary to manufacture one hundred different capsules with two compartments. Moreover, this solution of a manufacturing system with two separate capsules that will be manually assembled may appear as a deterrent since, unlike the capsule with two compartments pre-interconnected, it will be necessary to create manually a tight connection vis-à-vis the outside and a calibrated passage between the capsules that have been assembled together. In fact, given the small volumes and low pressures involved, the realization, even manual, of such a link and such a passage, has finally proved relatively easy.

To this end, the present invention proposes a system for manufacturing a cosmetic product comprising: at least one first disposable deformable capsule comprising a predetermined quantity of a first phase of a cosmetic product, at least one second capsule Disposable deformable syringe comprising a predetermined quantity of a second phase of a cosmetic product, said first and second phases being different from each other, said second capsule being completely separate from said first capsule, said capsules being structured so as to be able to be assembled together so as to be communicably connected to one another by a constriction, in a sealed manner with respect to the outside of said capsules, said capsules being sufficiently flexible and said narrowing being sufficiently narrow that a mechanical pressure exerted by a hand can transfer the e content of one of said capsules to the other of said capsules so as to homogenize, by passing through said narrowing, the mixture of said first phase and said second phase, said homogenized mixture being a cosmetic product directly consumable by the final consumer . To this end, the present invention further provides a first disposable deformable capsule 20 comprising a predetermined amount of a first phase of a cosmetic product: being completely separated from a second capsule of a product manufacturing system wherein said second disposable deformable capsule comprises a predetermined amount of a second phase of a cosmetic product, said first and second phases being different from each other, said capsules being structured so as to be able to being assembled together so as to be connected to one another in a communicating manner, by a narrowing, in a sealed manner with respect to the outside of said capsules, said capsules being sufficiently flexible and said narrowing being sufficiently narrow for mechanical pressure to be exerted by one hand can transfer the con holding one of said capsules to the other of said capsules so as to homogenize, by passing through said narrowing, the mixture of said first phase and said second phase, said homogenized mixture being a cosmetic product directly consumable by the final consumer .

Preferably, said narrowing between said capsules is sufficiently narrow and sufficiently long that a mechanical pressure exerted by one hand can transfer the contents of one of said capsules to the other of said capsules, so as to shear said contents. exiting said narrowing, said shear homogenizing said mixture of said first phase and said second phase. The manufacturing system then also has, as regards the final cosmetic product directly consumable by the final consumer, a homogenization which is much better than that of the final cosmetic product of the two prior arts previously presented. More particularly, in this preferred case, the embodiments of the invention aim to provide a system for manufacturing a cosmetic product, directly consumable by the end consumer, for which the mixture obtained is better homogenized. For this, the shrinkage between the assembled capsules of the system is sufficiently narrow to effect shear of the mixture exiting this shrinkage upon its transfer from one capsule of the system into the other capsule of the system. Advantageously, the capsules of the manufacturing system are of simple or simplified structure and their use to obtain the cosmetic product directly consumable by the final consumer is easy or facilitated. The essential parts of this manufacturing system are then advantageously the two capsules assembled together by a narrowing effecting the shear of the mixture passing through this narrowing.

3031092 6 The separation of the components or phases of the personalized cosmetic product, prior to their mixing, allows of course a greater flexibility and a greater richness in the possibilities of mixing to realize, that is to say a greater choice possible for the final consumer. The separation of the components or phases of the personalized cosmetic product, prior to their mixing, also allows on the one hand a better and a longer preservation before mixing, and on the other hand makes it possible to limit or even eliminate the preservatives that would be 10 required for a conventional product already mixed when sold to the final consumer. The health of the end consumer is then better preserved. The cosmetic product manufacturing system customized from pre-dosed capsules for single use is simultaneously simple and effective to use and secondly its cleaning is practically non-existent or at least very simple and quick to perform. In fact, preferably, this mixture does not come out of the medium consisting, on the one hand, of said capsules and, on the other hand, by the narrowing formed between said capsules, at all or at least not before the homogenization of said mixture has been completed. .

Thus, the mixing will take place inside the medium consisting of the two capsules connected together, without leaving this medium, and therefore without the risk of coming into contact with the outside of the manufacturing system, thus avoiding to dirty the outside environment. This is a simple and effective way for the contents of the capsules not to come into contact with the outside, without requiring other additional elements to achieve the mixing, the only capsules sufficient to achieve the mixing, another element. additional possible to be used to receive the mixture once it is made.

3031092 7 The lack of use of any machine responsible for performing the transfer from one compartment to another, does not prevent a possible preheating of one or the other of the capsules. According to preferred embodiments, the invention comprises one or more of the following features which may be used separately or in partial combination with each other or in full combination with one another. Preferably, said narrowing is in the form of a channel, at least over part of its length. Preferably, said channel is of constant section over most of its length, preferably over its entire length. Thus, the coupling of the acceleration of the mixture during the crossing of the channel with the pressure drop that accompanies it on the one hand, and the deceleration of the mixture after crossing the channel with the rise in pressure that accompanies it. on the other hand, promotes the shearing of the mixture after this crossing, and consequently improves the homogenization of this mixture. Preferably, said constant-section channel portion has a section of between 0.5 and 3 mm 2, preferably between 1 and 2 mm 2.

Thus, this low channel section value accelerates the mixing through the channel and lowers its pressure, the mixture then undergoing deceleration and pressure build-up at the outlet of the channel, thereby improving the shear of the mixture exiting the channel, shearing. which, becoming more important, improves the homogenization of the mixture.

Preferably, said constant section channel portion has a length of between 0.5 and 10 mm, preferably between 1 and 5 mm, more preferably between 2 and 4 mm. Thus, this combined effect of acceleration and pressure drop, favoring the shear of the mixture exiting the channel and improving its homogenization, occurs for a longer time, during the passage time of the channel.

Preferably, said channel opens into the capsules without entering the capsules. Thus, when the mixture returns to the capsule from which it came for a new crossing of the channel, it is avoided that a significant part of the mixture does not come jam in the cul-de-sac formed by the perimeter of the channel opening in the capsule. At each crossing of the channel, a blocked portion of the mixture would be less well homogenized, and the overall homogenization of the mixture would be less extensive for a given number of channel crossings.

Preferably, said capsules are each sufficiently large to contain all of said mixture, preferably sufficiently large to contain one and a quarter times all said mixture, still more preferably sufficiently large to contain one and one-half times all said mixture. Advantageously, the capsules are deformable but not extensible. Thus, with each transfer of the mixture from one of the capsules to the other capsule, the entire mixture passes through the narrowing, and not only the majority or a portion, thereby reducing the number of transfers required to achieve a level of homogenization given.

Preferably, said narrowing has a size or diameter which is at most 20% of the size or diameter of the capsule (s) which carry said narrowing, preferably at most 15%, more preferably at most 12%. Preferably, said narrowing has a size or diameter which is at least 2% of the size or diameter of the capsule (s) which carry said narrowing, preferably at least 4%, more preferably at least 8%. These ratio values between, on the one hand, the size of the shrinkage and, on the other hand, the size of the capsule or capsules, on the one hand, ensure a preferential maximum value of the relative shrinkage threshold, making it possible to obtain a particularly advantageous threshold of shearing. and therefore homogenization and secondly a preferred minimum value of the relative shrinkage threshold to maintain a passage time advantageously short to effect the transfer of the mixture from one capsule to another. Preferably, said first phase is a fatty phase, said second phase is an aqueous phase. Thus, being able to keep separated until the moment of consumption of the cosmetic product, the two phases, fatty and aqueous, the constituent, allow an optimal freshness of the cosmetic product as well as a good long-term preservation of the two separate phases in spite of the absence total or near total of preservatives in these two phases. Preferably, at least one of said capsules comprises one or more emulsifiers for stabilizing the homogeneity of the emulsified mixture and preventing the coalescence of said phases. Thus, once the emulsion has been produced by effective shearing and homogenization, this emulsion is easier to preserve without its constituent phases separating again by coalescence of droplets. Preferably, said capsules are structured so that they can be directly assembled together without an intermediate part.

Thus, the manufacturing system is very simple in its entirety. Preferably, at least one assembly base comprising at least two moving parts relative to each other, said capsules being structured so as to be assembled together, on said assembly base or not, said moving parts relative to each other being arranged so that their relative movement exerts a mechanical pressure on said narrowing so as to seal said narrowing relative to the outside of said capsules. Thus, this assembly base makes it possible to easily obtain the sealing vis-à-vis the outside for the narrowing at the assembly of the 3031092 10 capsules, at the price of a purely mechanical additional part and passive. Preferably, said assembly base is kept in contact with said capsules during said transfer or during said transfers.

Thus, this seal is preserved throughout the manufacturing process, that is to say throughout the process of homogenization of the mixture of phases, which mixture will, once well homogenized, the final cosmetic product directly consumable by the final consumer who manufactured it.

Preferably, said first capsule has a first narrowed exit tip, said second capsule has a second narrowed exit tip, said exit tips being narrowed differently with respect to each other so that, during said assembly, one end is inserted into the other at least partially.

Thus, the assembly of the capsules together is facilitated and all or part of the sealing vis-à-vis the outside of the manufacturing system and the capsules that compose it can be directly obtained in this way. Preferably, each of said capsules comprises a closed portion of said narrowing, the closure of said narrowing portions is located within said narrowing and is not located at the end portion of said narrowing. Thus, the assembly will be made easier by using a simple connector.

Preferably, a connector structured so that, when disposed between said two portions of said narrowing, and when the two capsules are interconnectedly connected to each other, said connector enters said portions of said narrowing so as to cause opening said portions of said narrowing.

3031092 11 Thus, this connector provides easy sealing vis-à-vis the outside for shrinkage at the assembly of the capsules, at the cost of an additional piece purely mechanical and passive. Preferably, said connector is pre-mounted on one of said capsules. Thus, the number of assembly steps to be performed manually by the end user is reduced. In a preferred embodiment, said first capsule comprises only one compartment, said second capsule comprises only one compartment. Thus, the overall structure of the manufacturing system and capsules that compose it is much simpler. In another preferred embodiment, said first capsule comprises two compartments respectively containing the first phase and a third phase different from each other and intended to be mixed together, a closed passage connecting said compartments to each other, said passage being sealed relative to outside said compartments, said compartments being sufficiently flexible, the outer wall of said passage being sufficiently solid and the closure of said passage being sufficiently fragile, so that a mechanical pressure exerted by a hand can open said passage while maintaining the tightness said passage relative to the outside of said conditioning compartments, said second capsule comprises two compartments respectively containing the second phase and a fourth phase different from each other and intended to be mixed together, a closed passage connecting said compartments between them, said passage being sealed with respect to the outside of said compartments, said compartments being sufficiently flexible, the outer wall of said passage being sufficiently solid and the closing of said passage being sufficiently fragile, so that a mechanical pressure exerted by a hand can open said passage by maintaining the seal of said passage relative to the outside of said packaging compartments.

Thus, two-phase two-phase complex mixtures can be made relatively simply by the sole consumer of the cosmetic product. First the first and third phases are mixed together to give a first mixture. Then the second and fourth phases are mixed together to give a second mixture. Finally, the first and second mixtures are mixed together to give the final cosmetic product. In one embodiment, the contents of the capsules are under vacuum. The deformable nature of the capsules of the manufacturing system 10 then facilitates the increase in volume required to effect the transfer of the mixture from one capsule to the other of the manufacturing system. In an alternative embodiment, the capsules are aseptic air bags only partially filled with one or more cosmetic product components.

The compressible nature of the air, in contrast to the constituents of the cosmetic product, in liquid form, then facilitates the increase in volume required to effect the transfer of the mixture from one capsule to the other of the manufacturing system. Preferably, the thickness of the capsules is between 5% and 30% of their length, preferably between 10% and 20% of their length. Preferably, the thickness of the capsules is between 20% and 60% of their width, preferably between 30% and 50% of their width. These size ratios facilitate the deformation of the capsules of the manufacturing system. This deformation then temporarily increases the volume-to-surface ratio of one or the other of the capsules, which is useful for easily accommodating the entire mixture passing through the constriction. The invention also relates to a method of manufacturing, by the end consumer, a cosmetic product directly consumable by the end consumer, from a system for manufacturing a cosmetic product according to the invention, characterized in that the transfer of said mixture from one capsule to another is carried out at least once, preferably at least twice, more preferably between two and seven times, more preferably between three and five times . Thus, by some traverses of the shrinkage, the mixture is well homogenized and can then be directly consumed by the final consumer. Other features and advantages of the invention will appear on reading the following description of a preferred embodiment of the invention, given by way of example and with reference to the accompanying drawings.

DETAILED DESCRIPTION OF THE INVENTION FIGS. 1A and 1B show schematically, respectively in plan view and in profile view, an example of a manufacturing system 20 according to one embodiment of the invention, shown in a corresponding state. at a first phase of a manufacturing method according to one embodiment of the invention. The manufacturing process will now be described in connection with a manufacturing system 3 containing a first phase which is a fat phase and a second phase which is an aqueous phase. The fatty phase constitutes the base of the cosmetic product to be manufactured whereas the aqueous phase comprising active elements constitutes the complex of active ingredients of the cosmetic product to be manufactured. The manufacturing process will function similarly with a fatty phase and an aqueous phase both containing active elements, or with two aqueous phases, or with another combination of phases, the mixture of which will give the directly consumable cosmetic product. by the end consumer. The final consumer is a generic term that refers to both a female final consumer and a male final consumer. A manufacturing system 3 comprises two capsules 1 and 2. In the capsule 1 is a first fatty phase of a cosmetic product. In the capsule 2 is a second aqueous phase of a cosmetic product. Capsules 1 and 2 are, for example, pre-filled and sealed flexible tubes. The capsules 1 and 2 each have the same dimensions, a length L, a width 1, a thickness e.

The capsule 1 has a frustoconical portion 11 which is terminated by a closed tip 5. The capsule 2 has a frustoconical portion 12 which is terminated by a closed end 6. On the closed end 5 is mounted a connector 4. The end piece 5 is inserted into one end of the connector 4. The end piece 6 will also be introduced into the other end of the connector 4.

It can also be the connector 4 whose ends are introduced respectively into the end pieces 5 and 6. The connector 4 is structured so as to open the closed ends 5 and 6 while constituting with these end pieces 5 and 6 a channel. This channel is of virtually constant section. The more detailed structure and operation of this connector 4 will be described in FIGS. 6A and 6B. The capsules 1 and 2, as well as the channel, will be sealed with respect to the medium outside the manufacturing system 3. FIGS. 2A and 2B show schematically, respectively in plan view and in profile view, an example of a control system. manufacture 25 according to an embodiment of the invention, shown in a state corresponding to a second phase of a manufacturing method according to one embodiment of the invention. The horizontal straight arrows symbolize the approach of the capsules 1 and 2 towards each other along the axis of the connector 4, made by the final consumer. The star 8 symbolizes the opening of the closed ends 5 and 6 by the connector 4 when the final consumer continues to bring the capsules 1 and 2 towards each other, bringing them into abutment against the ends of the connector 4 In a first step, at the level of FIG. 2A, the end consumer introduces the tip 6 closed in the connector 4, pushes the capsules 1 5 and 2 towards each other until the connector 4 opens the tips 5 and 6 and until the capsules 1 and 2 come into abutment against the ends of the connector 4. At this time, the transfer of the contents of a capsule to another capsule can be made through the channel 10 located inside the connector 4.

The vertical straight arrows symbolize the manual pressure exerted by the end consumer. The horizontal curved arrow symbolizes the transfer of the contents of a capsule to another capsule of the manufacturing system. In a second step, in FIG. 2B, when the final consumer exerts a manual pressure on the capsule 1, this capsule 1 flattens out, which has the consequence of expelling the first fatty phase out of the capsule 1. The first fatty phase expelled out of the capsule 1 passes through the channel 10 located inside the connector 4. The first fatty phase, after passing through the channel 10 located inside the connector 4, is found in the capsule 2 where it can mix with the second aqueous phase contained in the capsule 2, to give the mixture 7 which is at this stage not at all homogenized. FIG. 3 schematically shows, in profile view, an example of a manufacturing system according to one embodiment of the invention, shown in a state corresponding to a third phase of a manufacturing method according to an embodiment of the invention. When the final consumer exerts a manual pressure on the capsule 2, this capsule 2 flattens which has the effect of expelling the mixture 7 out of the capsule 2. The mixture 7 expelled out of the capsule 2 30 through the channel 10 located inside the connector 4 which is of constant section. The mixture 7, after passing through this channel 10, is found in the capsule 1, more homogenized, thanks to its crossing of this channel 10 which has a reduced passage section relative to the section of the capsules 1 and 2. indeed, the section restriction at the channel 10 located inside the connector 4, creates, for the mixture 7 which passes through this channel, an acceleration of flow and a decrease of pressure, which contribute, with the reduction of section shearing the fatty and aqueous phases contained in the mixture 7 not at all homogenized at the outlet of the channel 10. The mixture 7, after having passed through this channel 10, arrives in the capsule 1.

This channel 10 is of substantially constant section. The channel 10 is advantageously completely free of any obstacle or toasting. The mixture 7 then undergoes a strong turbulence when it pours into the capsule 1, because it undergoes both a deceleration and a rise in pressure, which contributes to the shear of the fatty and aqueous phases contained in the mixture. at all homogenized. The shearing of the mixture 7 after crossing the channel 10, created by this strong turbulence, homogenizes the mixture 7 which begins to become an emulsion. FIG. 4 shows schematically, in profile view, an example of a manufacturing system according to an embodiment of the invention, shown in a state corresponding to a fourth phase of a manufacturing method according to an embodiment of the invention. When the final consumer exerts a manual pressure on the capsule 1, this capsule 1 flattens which has the effect of expelling the mixture 7 out of the capsule 1. The mixture 7 25 expelled out of the capsule 1 passes through the channel 10. The mixture 7, after passing through the channel 10, is found in the capsule 2, even more homogenized, thanks to its new crossing of the channel 10 which has a reduced passage section relative to the section of the capsules 1 and 2 Indeed, the section restriction at the channel 10 creates, for the mixture 7 which passes through the channel 10, at each passage of the mixture 7, a flow acceleration and a pressure decrease. The mixture 7, after having passed through the channel 10, arrives in the capsule 2. The mixture 7 undergoes, when it pours into the capsule 2, both a deceleration and a rise in pressure. The successive combination on the one hand of the acceleration and the pressure drop on the other hand followed by the deceleration and the rise in pressure homogenizes the mixture 7 and promotes its emulsion. The cycle of passage of the channel 10 by the mixture 7 going from one capsule to another, can be repeated several times until the desired emulsion is obtained. The mixture 7 passes alternately from the capsule 2 into the capsule 1 and then from the capsule 1 into the capsule 2, each time passing through the channel 10. The number of passages of the channel 10 made by the mixture 7 may vary according to the composition specifies phases of the cosmetic product. A number of crossings between 3 and 5 is suitable for most cosmetic products. The number of passages of the channel 15 to be made to the mixture 7 may be indicated on the packaging of the manufacturing system 3 for the final consumer or on the packaging of one or the other of the capsules; a variable number of crossings may be indicated on the package of a capsule according to the other capsule to which it will be associated.

FIG. 5 diagrammatically, in profile view, an example of a manufacturing system according to an embodiment of the invention, represented in a state corresponding to a fifth phase of a manufacturing method according to an embodiment. of the invention. Once the desired number of crossings have been made, the mixture 7, well homogenized and, if appropriate, well emulsified, is found in the capsule 1. The capsules 1 and 2 are separated from each other. The capsule 2, empty of cosmetic product, can be crushed and discarded. The capsule 1, the tip 5 is still in the connector 4, contains the well-homogenized cosmetic product, the directly applicable emulsion. Normal manual pressure on the part of the final consumer causes the mixture to be expelled 7 which can then be poured into a cup 9 and then directly consumed by the end consumer who can apply it directly to the face at the end of the day. help from his fingers. FIG. 6A schematically represents an example of a detail of the cooperation between a connector and the caps of capsules in a manufacturing system 5 according to one embodiment of the invention, in a state corresponding to a first stage of the second phase of FIG. a manufacturing method according to one embodiment of the invention. The connector 4 comprises a stop 13 on each side of which are disposed two pipes 14 and 15, in fact two portions of the same pipe, the stop 13 being in fact a tight ring on this pipe. Each endpiece, 5 and 6, is respectively closed by a closure 16 and 17, for example of the cap type to be pierced. The closures 16 and 17 are respectively located in the end pieces 5 and 6, but not at the respective ends 18 and 19 of these end pieces 5 and 6.

The connector 4 is pre-mounted on the nozzle 5, the pipe 14 already being introduced into the nozzle 5. The outer diameter of the pipe 14 is equal to or slightly greater than the inner diameter of the nozzle 5 to be able to be fitted into it without leaving a radial gap between pipe 14 and nozzle 5 and without allowing leakage of liquid between pipe 14 and nozzle 5 when the mixture will be transferred from one capsule to another. The connector 4 is mounted on the end-piece 6 by the final consumer who introduces the pipe 15 into this end-piece 6. The outside diameter of the pipe 15 is equal to or slightly greater than the inside diameter of the end-piece 6 in order to be able to be fitted in without leaving radial space between pipe 15 and 25 tip 6 and without allowing leakage of liquid between pipe 15 and tip 6 when the mixture will be transferred from one capsule to another. FIG. 6B shows schematically an example of the detail of the cooperation between a connector and the caps of capsules in a manufacturing system according to one embodiment of the invention, in a state corresponding to a second stage of the second phase of FIG. a manufacturing method according to one embodiment of the invention.

When the final consumer brings the two end pieces 5 and 6 closer to each other until these ends 5 and 6 abut against the abutment 13, the ends of the pipes 14 and 15 respectively pierce the closures 16. and 17, for example of the operculum type. A channel 10 of substantially constant section 5 has been created inside the connector 4, it extends inside the nozzle 5, then inside the pipe 14, then inside the pipe 15, then inside the tip 6. This channel 10 connects the capsules 1 and 2 between them. Of course, the present invention is not limited to the examples and embodiments described and shown, but it is capable of many variations accessible to those skilled in the art.
