专利说明:

[0001] The present invention relates to methods and dispensing systems, especially a makeup product. Many people want to wear makeup to beautify their appearance, including their faces.
[0002] The motivations of these people can fall into two categories: - mask some imperfections, such as spots, wrinkles or pores, - beautify the rendering of the face by color changes. In both cases, the operation is to bring a colored material and to cover the skin or skin area. To obtain an aesthetic effect, the person must succeed in choosing the colored material. In the first case above, the operation can be complex because the face has a range of colors.
[0003] Thus, if the person wants to cover only a few areas of the face, trying to match the color added to the natural color of the surrounding skin, it is necessary to find the appropriate color for each area of the face, which is all the more difficult as the coverage of the product and the thickness deposited, as well as the color and the surface condition of the underlying skin or its more or less greasy nature, can influence the result. Given these difficulties, people who want to hide the imperfections of their face, usually cover the entire face. We then bypass the problem of choosing the colored material according to the area of the face. However, the result is removed from the natural appearance of the face by the homogeneity provided.
[0004] In the second case, the operation is not easy either because it is difficult to find the colored material that best suits the appearance of the face. In particular, it is difficult to find the color of his complexion, especially if one wants to choose a marked color, different from its natural color. Some people would like to choose tan colors or different shades of complexion, but they do not do it for fear that the color does not match them well. And if they do, they often give up, disappointed. When they are not disappointed with the result, they dare not change their color.
[0005] It is the same for the makeup of the lips and that of the cheeks and eyelids. To solve these problems, there are few solutions. A first approach is to buy many products and to try them all. This approach is expensive and often generates losses in that only a small number of the colored materials tested are retained. A second approach is to test, in store, different products. It does not always fit, because it is very difficult to imagine the result in a few moments and in a place devoid of usual benchmarks. In particular, to fully appreciate the effect of makeup in a store, it should be able to illuminate in the same way as in future conditions of use, which is rarely possible. In general, it is only by testing a makeup during the day, that one realizes whether it is appropriate or not. In addition, although some stores have advisors and allow testing, this is not the case for many other outlets and purchases made on the internet. Another approach has been tested but not developed. It consists in manually producing its products by mixing several color products. This can be relatively difficult to implement because it is difficult to reproduce exactly the same mixture exactly several times, and it is difficult to quickly achieve the mixtures that are needed at the time of makeup. Distributors are also known for delivering a cosmetic composition of variable color. US2003069667 relates to methods and apparatus for personalizing cosmetic products used by a consumer. The latter provides choice criteria and a cosmetic product formula is derived from it. The basic ingredients are mixed according to the formula and a personalized cosmetic product is dispensed on an intermediate surface for later application. US Pat. No. 5,785,960 discloses a process for obtaining foundations that are suitable for covering the imperfections of human skin. The steps of the method include spectrophotometrically measuring a normal skin of a client to obtain shine, red, and yellow skin color values respectively denoted as L, a, and b units. Then these values are converted by calculation into modified values determined by a program for correcting the values L, a and b. According to these modified values, a foundation is formulated. A remote formulation machine converts received instructions and dose and mix a series of commodities. The mixture delivered by the machine is packaged and shipped to the customer.
[0006] The application FR2970403 discloses a device for dispensing a cosmetic product, in particular a perfume, comprising at least one reservoir containing a product to be dispensed, in particular several reservoirs, and a rinsing device. The device can be controlled using a microcomputer or the like. A human-machine interface, for example a keyboard or a screen, in particular tactile, allows the user to order the distribution of a formula of his choice. The device can be arranged to communicate with a server or other similar devices to exchange recipes or allow the user to be advised. A memory of an electronic circuit of the device can record the best formulas, in order to reproduce them on demand and to exchange them. The device can also be used to make mixtures of colored cosmetics. A certain amount, for example a drop, of colored composition is then produced by the device and is used to make up or is to be mixed with a cream of complexion or any other colored base or not. The device makes it easy to generate the color desired by the user, who can for example perform in a few moments several mixtures of different colors.
[0007] The patent application FR2818101 relates to a device for spraying a cosmetic product, especially a foundation. It is possible to make an extemporaneous mixture on the treated substrate. The application FR 2877819 describes a distributor for varying the relative proportion of different basic products that are distributed. It is thus possible to adjust the color. Commodities come from different tanks and are distributed through separate channels that open side by side at one end of the dispenser. A disadvantage that results is that the user must perform the mixture on the skin or on an intermediate support. Moreover, if the quantity distributed is excessive, it is lost.
[0008] US 5,622,692 and U55903465 describe other examples of dispensers for dispensing a personalized cosmetic composition.
[0009] Among the attempts to automate the manufacture of a personalized cosmetic composition that have been attempted, many are those in which the proposed solutions allow mixtures to be made in amounts of about 100 g or sometimes less, but not in the very small proportions that the person who wears makeup usually needs, that is to say in the order of a gram or much less. To illustrate this problem, one can imagine the case of a person who wants to hide two imperfections of the order of cm2 on his face. For the first zone, it needs to find the corresponding mixture, then to deliver a very small amount, for example about 10 mg. For the second, she needs to change the setting of the dispenser, then deliver a very small amount as well. Therefore, the choice of the best performing colored materials remains difficult for a large number of people. There is therefore a need to facilitate the search for a makeup product meeting the expectations of a consumer, and allowing it to make mixtures in reliable conditions and in very small quantities. The invention thus aims, according to some of its aspects, to facilitate the makeup of the face and in particular the search for the most suitable products in the different areas of it. There is still a need to improve distribution systems for delivering products of varying color, including to facilitate their use and improve the quality of makeup. According to certain aspects of the invention, the invention relies on a distribution system that makes it possible to generate mixtures from basic products. These basic products may have different colors, so that the color of the mixture can be varied. The base products can still make it possible to vary the coverage of the mixture, so that the color which results from the application of the mixture to human keratin materials varies, being more or less close to that of said materials. Thus, the notion of color must be understood with wide acceptance and includes mixtures whose color varies after application because of their higher or lower coverage and the color of the underlying skin.
[0010] The invention makes it possible to treat one or more areas of the face. Subsequently, the term "zone" denotes a part of the face defined and rather reduced in area, with an extent of between 1 cm 2 and 100 cm 2, better ranging from 2 cm 2 to 50 cm 2. Dispensing System The dispensing system can consist of a single device operating autonomously, preferably manipulable with one hand, or by a device that operates by interacting with other parts or devices. It may be for example different output interfaces that are mounted on the dispenser depending on the type of makeup to achieve, as will be explained below. It may also be a computer system that exchanges information with the distributor to control it, this computer system comprising for example a portable terminal such as a smartphone, a photophone, a tablet, a personal computer, or a computer. dedicated terminal. Preferably, the dispenser is arranged to pressurize one or more compartments containing the base product or products, by means of volumetric dosing devices, preferably a motor displacing a piston in the corresponding compartment. The dispenser may be formed of a housing and at least two or three compartments, and preferably as many engines. For example, the rotation of the motors drives worms, which push the pistons of each compartment. The advance of the pistons is for example controlled by the number of control pulses sent to the motors and / or by the operating time of the latter. The motors can be fed sequentially, or preferably simultaneously. For example, the motors are fed during a short operating cycle for a short time one after another, or at the same time as the others, so as to distribute corresponding microdoses. The elementary cycles are repeated, possibly with a pause between them, which allows time for the commodities to flow out of the compartments. Compartments can be defined by cartridges that retract when empty. Alternatively, the compartments are permanently present and filled again once empty. Each cartridge can be closed with a removable cap to allow cleaning of the cartridge.
[0011] Preferably, the dispenser housing is of elongated shape along a longitudinal axis, which can facilitate its handling, and the cartridges are arranged around this axis in the housing. Preferably, the cartridges are put in place from the rear, and the mixture is delivered from the front. The introduction of the cartridges can be carried out individually, or alternatively the cartridges constitute a one-piece assembly when they are put in place. The cartridges may each have a volumetric dosing mechanism, having a piston driven by a dispenser drive mechanism, in a direction accompanied by a decrease in the interior volume containing the base product and an expulsion of the product. It may be interesting that the cartridges have at least one region of their wall that is transparent, to allow to see the color of the product contained inside. The drive mechanism may comprise a motorization system formed of motors coupled to gearboxes, of elongate shape parallel to the longitudinal axis of the distributor, and arranged between the cartridges. This positioning of the motors and cartridges makes the dispenser particularly compact. The base product can leak tightly from the corresponding cartridge and then circulate in a channel provided for this purpose in the distributor housing, before leaving it.
[0012] The cartridges are advantageously terminated by a nozzle made so that, once the cartridge inserted into the dispenser housing, the end of the nozzle opens flush with the housing. Alternatively, the tip is long enough to protrude from the housing and thus connect different output interfaces may be reported on the valve housing.
[0013] Thanks to the drive mechanism with motors for advancing pistons, it is possible to accurately deliver mixtures in very small quantities. Thus, it is possible to deliver the basic products with flow rates as low as 101 l / s, and preferably with flow rates ranging from 20 to 100 l / s. It is therefore possible to easily make a mixture of about 10 mg. Such a dispensing system is then ideal for making small touches of makeup, to cover for example a small area of 1 cm2 or less.
[0014] It is also possible to make larger amounts of mixture such as those needed to make up a cheek, or a face. These quantities remain nevertheless relatively low, for example from 100 to 500 mg. The invention thus has, according to one of its aspects, a dispensing system comprising a dispenser having a housing, and at least one cartridge received in the housing of the ditributeur, this cartridge comprising a body and a movable piston in the body, the housing having a motorized drive mechanism for moving the piston of the cartridge. Preferably, the cartridge comprises a dispensing nozzle through which the product is dispensed, and this dispensing nozzle is rotated by the drive mechanism to move the piston. The tip may comprise at least one anti-rotation relief, better two anti-rotation pins diametrically opposed The tip may carry a seal, including an O-ring. Thus, at the cartridge change, the seal is also changed, which makes it possible to overcome the wear of the seal. The dispenser may include an electronic control board of the motorized drive mechanism, this electronic board being traversed by the end or ends. This can make it possible to make a card extending substantially over the entire section of the dispenser, so to consolidate on a single card all the electronic components of the dispenser, and thus to gain in compactness and reliability. The card may extend substantially perpendicular to the longitudinal axis of the housing. The card can carry a switch controlling the operation of the dispenser. The dispensing system can be arranged to operate in at least two modes of distribution.
[0015] In a first mode, called "continuous", the mixture is distributed as long as pressure is exerted on the control switch. In a second mode, called "dose", a predefined quantity of the mixture is dispensed with each pressure on the switch. The tip or ends can lead to one end of the housing. This can reduce the dead volume, as will be detailed later. The tip or ends may have at their end a closure system to prevent drying of the products in the conduit, for example a healing membrane The cartridge may comprise a hollow screw on which the piston is screwed, the piston being able to move axially on the screw when it turns; the piston is prevented from turning in the body of the cartridge. For example, piston friction on the cartridge body may be sufficient to prevent it from rotating as the screw rotates.
[0016] Preferably, the rotation is made impossible with a cartridge body of non-circular section and a non-deformable piston. The torque of the motors can be determined electronically according to the current absorbed, and serve for example to detect a limit of the piston stroke. Information about the torque can be transmitted remotely to a computer system having a human machine interface, to allow monitoring the proper operation of the dispenser. In order to adjust the hue, the dispensing system according to the invention must allow the user to vary the delivered volume from each compartment.
[0017] Preferably, the dispenser is controlled by a computer system, which is integrated in the dispenser, or external to it, the dispenser then being able to exchange information with the computer system by wireless or wired protocol. The dispenser can thus be controlled to allow the adjustment of the color by simultaneous or sequential distribution, and controlled, of several commodities of different colors. The distribution of commodities can be continuous; if in this case, the volumes of each of the basic products are distributed in one go, simultaneously or successively. In the case of a simultaneous distribution, it is useful to be able to adjust the respective flow rates of the different basic products so that the mixture distributed corresponds to that desired at each moment. Such a mode of distribution may be particularly suitable when dispensing the mixture by spraying, using an airbrush. To adjust the flow rates it is possible for example to play on the speed of movement of the pistons, for example, in the case of driving the pistons by a worm by varying the speed of rotation of the motors that drive the screw. The products can also be impulse distributed with a dispensing time and a stopping time at each cycle. By playing on the duty cycle, it is possible to act on the flow.
[0018] All products can be delivered simultaneously during the distribution time; alternatively, the cycles of the different products are out of phase, so that a product is distributed during a downtime of the other products.
[0019] In a particular embodiment of the invention, the mixture is delivered into a cavity of a container, which can be closed hermetically or otherwise, for example in the form of a cup, into which an applicator can be slid, in particular a stylet or a brush. Such dispensing system is specially adapted for liners, glosses and other formulas applied without direct contact with the hands. This container can be removable.
[0020] For example, it serves as a distributor of lipstick and has a dispensing system, screw for example. When not removable, the container can be made with the body of the dispenser. When removable, it can be an output interface among others that can be mounted on the distributor. The compartments, and in particular the cartridges, may contain all or part of the drive mechanism, and for example the motorization system, or better, a part of the motorization system, and this, in order to reduce the number of moving parts in the dispenser body on the outside of the cartridges. For example, the cartridges include the motor rotor. Once the cartridges are installed in the distributor body, the rotors are brought into interaction with the stators.
[0021] The dispensing system is advantageously arranged to allow to start preprogrammed sequences in which the mixture delivered by it is changed continuously or discontinuously. A "degraded" mode makes it possible, for example, to progressively change from a mixture A to a mixture B. In the case of an application by spraying, in particular using an airbrush, this makes it possible to simply perform the gradients. An "Alternate" mode makes it possible, for example, to quickly switch from a mixture A to a mixture B several times in succession. In the case of a spray application, it is thus possible to produce a multilayer deposit, with different formulations for two superposed adjacent layers. Another mode makes it possible, for example, to propose several successive preprogrammed mixtures, the computer system indicating each time the use to be made of it by the user, for example by display on a screen. In the case of a manual application, the mixtures are distributed for example in a cup. The person wears makeup in the recommended place with a corresponding mixture taken from the cup, then cleans the cup and orders the delivery of a new mixture; the operation is repeated as many times as necessary to make up completely. The homogenization of the distributed mixtures can be done in different ways depending on the use case. In the case of a manual application, it can be done directly on the application area at the time of application or in the cup before sampling; in the case of an airbrush application, it is the nozzle of the airbrush which serves as a mixing chamber; in the case where the mixture is dispensed into a container for later use, the homogenization can be done by hand or by passing the products distributed in a mixing chamber, located between the dispenser and the container or directly included in the container, as detailed below. The product can be delivered by the distribution system and used extemporaneously. As a variant, the product delivered by the dispensing system is packaged and used subsequently, for example several times, with for example an interval day at least between two uses. Use for the make-up of one or more specific areas of skin The dispensing system makes it possible to apply makeup day after day, by treating only the areas to be masked. To do this, we deliver small doses of makeup, which is applied precisely and sequentially on the corresponding areas. Each small dose is made according to the mix that suits the area. In a preferred embodiment of the invention, the dispensing system waits for information on an area to be treated and delivers the corresponding mixture. It may use a correspondence table preprogrammed for this, this table resulting for example from a learning method as defined below. Alternatively, the dispensing system informs the person, while delivering a mixture, on the area on which it must apply the mixture. Thus, the dispensing system can follow an application program where it delivers in a given order, the different mixtures to be applied. In a particular embodiment of the invention, the distribution system is informed about the quantities to be delivered. For this, it memorizes the correspondence between the color, the area of the face and the necessary quantity, which makes it possible to reduce the costs and the losses of product, and to cover only weakly the skin, thus avoiding effects of occlusion. In doing so, it is possible to use very covering products and too covering to be applied on the whole face. Thus, it is possible to obtain makeup natural aspects, even undetectable. The distribution system can also, by facilitating the distribution of small quantities and their rapid use, reduce the shelf life of products, thus reducing the risk of change and / or the amount of preservatives to use. The dispensing system is adapted to treat the areas you want to hide, without having to hide the entire face.
[0022] When the user searches for the color to be applied to an area of the face, it is interesting to memorize the color that goes well for each zone, and the dispensing system is thus advantageously arranged to memorize this color and the corresponding zone. Thus, using the stored information, with each use, it is possible to obtain the delivery of the same mixture for each zone, or, if one treats several zones, the same series of mixtures for the same series of zones. The dispensing system can also be arranged to allow a zone to be treated by varying the application colors after application. Thus, the person can make up the lips with different colors, which she chooses day by day according to her tastes. This approach is also suitable for eyelids or eyelashes, as well as face makeup because the person may want to change the color of complexion. For example, the days of the week, the person carries out a light-colored foundation, and the weekend, a foundation of tinted color, or an eye makeup of a color one day, and another color a other day. The dispensing system can be arranged to allow the user to change color according to his tastes of the day, the moment, his outfits, the climate. Thus, it is advantageous to provide a decision support system to guide the user in his color choices. We can also provide a help system to balance the colors on the same face and participate in achieving a successful overall makeup.
[0023] It may be desirable for several people from the same group, such as a family, to be able to use the distribution system, thus reducing costs and minimizing the space occupied. This solution is especially adapted to travel or hotels, campsites, planes, motor homes, shops, schools ... To do this, we can predict that the distribution system can be informed about the person who uses it, in order to access to previously stored personal data. Continuous use for gradient makeup In this application, the dispensing system, while delivering the product, changes the formulation of the mixture. In addition, the output of the commodities or mixture is moved relative to a container or carrier defining an application surface. In a particular embodiment of the invention, the distribution system is arranged to calculate the evolution of the mixture as a function of the color C1 of an area to be treated and the color C2 of another area to be treated. For example, knowing that the chin requires a color C1 and that the cheek requires a color C2, the dispensing system can vary the formulation of the mixture while it delivers to color a gradient between these two colors. This allows, for example, to better hide the imperfections of the face by making the final result realistic, or to make color gradients for embellishment purposes. The dispensing system can be further arranged so that the user can control a color variation of the dispensed mixture without the starting and / or arrival colors being previously fixed. To do this, the distribution system can have a location system, or self-location, and deduce from a correspondence table the colors C1 and C2 that it must achieve, and therefore the changes in mixing that he must realize. The dispensing system may include an exit head, particularly in the case of an airbrush, which is mobile and driven. This option then allows, without moving the rest of the distribution system, to make gradients. For example, it locates the distribution system near the cheek, then triggers a control system that will automatically control the variation of the formulation of the mixture and the movement of the output head, so for example to have the center of the cheek is more red than its periphery, with a gradient between the two. The distribution system can still be used to produce customized products, which are kept for several applications.
[0024] It is also possible to produce solid or semi-solid products.
[0025] Manufacture of compact "toll" or other solid or semi-solid products The dispensing system can be arranged to allow to choose a mixture and deliver it in a container such as a cup. The mixture preferably comprises compounds which are such that the mixture can set in bulk.
[0026] More preferably, compounds are used which make the setting in mass especially fast. These compounds are either deposited in the container before or after filling with the other constituents, or are provided in the dispenser compartments with the other constituents of the basic products, or are included in the dispenser in a compartment specifically designed to contain them.
[0027] It is thus possible to dispense specific compositions which can, by chemical, biochemical or physicochemical reaction, harden in an accelerated manner after evacuation. These compositions are especially adapted to the production of compacts, that is to say: - Take in mass, - give a material which can disintegrate in case of friction, and are - preferentially colored. Preferably, these compositions are very rich in solid particles, with for example more than 30% by weight of solid particles relative to the total weight of the composition. These compositions may contain absorbent particles, or reactive compounds, such as those which react in contact with air, for example cyanoacrylate or alphasilanes, or which react with light, especially UV. The container in which the mixture is dispensed may comprise a compound A and the compositions distributed a compound B, A and B being chosen to react with each other and solidify the mixture.
[0028] In a particular embodiment of the invention, the dispensing system incorporates a heating means, for example electrical resistance, for producing lipsticks or other waxy products. In this case, the basic products are heated before being delivered. The dispensing system may also include a means for supplying energy, thermal and / or light, after distribution of the mixture in a container, for example an electrical resistance or an LED diode, especially UV. This energy can accelerate the setting in mass of the distributed mixture.
[0029] Preferably, the mixture is homogenized before caking. Realization of color palettes The dispensing system can comprise a support, having several regions, and be arranged to automatically generate several mixtures deposited in said regions, for example a series of colors adapted to different parts of the face. The support may define several cavities to receive the mixtures or to carry several containers, for example in the form of cups, possibly separable from the support. In a particular case, the support takes the form of a face with regions to receive the mixtures for targeted application areas. The support is mobile, in particular rotatable, relative to the body of the dispenser, and for example driven on the move by the dispenser, to successively fill different housings or containers. Cup dispenser There is an interest in benefiting from a dispensing system capable of delivering a mixture that can be easily removed by the user. On the other hand, in the case where the basic products delivered by the dispensing system are not already mixed, there is a need to allow the user to easily mix. According to one of its aspects, independently or in combination with the other aspects thereof, and in particular with the foregoing, the subject of the invention is a system for dispensing at least one make-up product, comprising a cup , and a dispenser for filling the cup with at least one product, the cup being secured to the dispenser at least during its filling. The cup is sometimes called "crucible" and this term must be understood with broad acceptance. By "integral cup of the dispenser" it is to be understood that the cup is retained, in particular immobilized, at least temporarily on the dispenser, for example being fastened to it by screws, by magnetization, by snapping, by locking bayonet, by clamping , or made with a part of the body of the dispenser by molding of material. The cup when it is secured to the dispenser allows to manipulate it with one hand, the cup remaining in place on the dispenser during the movements of the latter.
[0030] The dispenser can be offered to the user with the cup already in place. Alternatively, it is installed by the user at the first use of the dispensing system. Preferably the cup is shallower than wide, which facilitates access to it, and allows to take the product, including mixing with an applicator or finger. Preferably, the cup is separable from the dispenser, and constitutes an output interface which can be chosen from among a set of output interfaces that can be mounted on the dispenser, at the user's choice according to the make-up to be produced, as detailed further. Preferably, the dispensing system comprises several filling holes in different basic products, opening into the cup. Thus, the mixture of these products can take place in the cup. The cup preferably has a bottom of concave shape to the outside, which can facilitate cleaning by the user between two uses. In addition, this can facilitate user sampling of the product, and the mixing of commodities. Preferably, the dispenser makes it possible to deliver at least two basic products into the cup, in adjustable proportions, and better at least three products.
[0031] In an exemplary implementation, the dispensing system comprises at least two cups that can be selectively fed by the dispenser. This can allow the user to quickly fill these two cups with mixtures whose characteristics are different. This can facilitate the testing of colored materials, and / or allow to prepare several mixtures of different colors for the makeup of respective areas of the face. The cups can be associated with identifiers reminding the user to which area of the face a mixture contained in a given cup is intended. The cups may be movable relative to the dispenser, for example being carried by a movable support, such as a turret movable in rotation relative to the dispenser, or by a spool movable in translation relative to the dispenser.
[0032] The dispensing system may include a closure lid of the cup. This closure lid is preferably transparent to allow the user to view the color of the mixture contained therein. When the cup is separable from the dispenser, it can be introduced if necessary into a housing for transporting it more easily, this housing possibly comprising a mirror and / or an applicator. The housing cover can in this case serve as a cover for the cup. The volume of the cup may be between 2 and 1000 mm3. The basic product or products delivered in the cup are preferably foundations, but alternatively they are makeup products for the lips or eyelids. The cup is preferably of symmetrical shape of revolution. Alternatively, it is polygonal or other contour. Its largest inside diameter, or that of the circle inscribed in the case of a non-circular contour, is preferably between 2 and 100 mm, preferably 5 to 40 mm. Its depth is preferably between 1 and 10 mm. Preferably, the size and shape of the cup allow either a direct application of the mixture on the skin, or a finger grip or with an applicator. The cup may be made of an elastically deformable material, which allows for example to invert the concavity of the bottom of the cup and empty it more easily or use it to apply the product. The cup may be devoid of mixer; in this case, the basic products may arrive from the dispenser into the cup in the unmixed state, through respective separate dispensing orifices. Alternatively, the dispenser incorporates a mixer and the basic products arrive already mixed in the cup.
[0033] The cup may also incorporate a static mixer, as detailed below, which is fed by separate filling ports of the dispenser, and which preferably delivers the mixture into a cavity of the cup located above the mixer. The invention further relates to a method for preparing a makeup product, comprising the step of filling a cup of a dispensing system as defined above with at least one base product from the dispenser.
[0034] Several products can be delivered in the bottom of the cup, then mixed with the finger or an applicator, or a static mixer built into the cup. The cup is preferably filled from below.
[0035] It has been proposed in the past distribution systems using a sonotrode. The cup according to the invention is not intended to vibrate to distribute the product or products brought by the supply channel or channels thereof. It is different from a sonotrode. Preferably, the cup is made of plastic.
[0036] Mixer integrated in the exit interface There is an interest in benefiting from a distribution system capable of delivering a mixture which can be easily used, in particular taken by the user, without requiring an additional mixing action on the part of the user. this. According to one of its aspects, independently or in combination with the other aspects thereof, and in particular the foregoing, the subject of the invention is a distribution system comprising a distributor having commodity output channels and a separable outlet interface of the distributor, this interface having a static mixer, preferably delivering the mixture into a cavity where it can be taken. The static mixer may be located under the aforementioned cavity. The dispensing system is then particularly suitable for creating compacts, using as output interfaces cups with integrated static mixer. In this case, the cavity of the cup is filled with product from below. After passing through the static mixer, the mixed base products cover the mixer. According to this aspect of the invention, it is possible to use a plurality of output interfaces and fill them with respective different mixtures, without having to purge the mixer, which reduces product losses. The output interface may be single-use, if applicable. Preferably, the static mixer comprises a central chamber communicating with intake channels of the basic products. This central chamber 30 may communicate with a peripheral chamber having a series of partitions which act as baffles for mixing, and create shear thereof.
[0037] The peripheral chamber may comprise a perforated annular partition defining openings through which the mixture passes while circulating in the peripheral chamber. The central and peripheral chambers can be closed superiorly by a wall which defines the bottom of the cavity receiving the mixture.
[0038] The bottom of the peripheral chamber may be helically shaped around the axis of the cup and decreasing in height as one progresses towards the exit. The latter may lead forward a connecting ramp between the bottom of the peripheral chamber and the upper wall of the mixer, this connection ramp being preferably a helical portion extending the helix formed by the bottom wall of the peripheral chamber. Preferably the peripheral chamber comprises the aforementioned annular partition and radial partitions which force the mixture to circulate alternately between upper and lower regions of the peripheral chamber and between radially inner and outer regions, the mixture circulating for example from an upper region. and radially external to a lower and radially outer region passing through the aforementioned annular partition. The mixer may comprise an outer body in which is received a part forming the core of the mixer, the outer body radially closing on the outside of the peripheral chamber and having an amount which separates the central and peripheral chambers. The outer body of the mixer and the core of the mixer can each be made in one piece by injection molding. Reduced dead volume There is an interest in reducing product losses during changes in the formulation of the mixture, as well as in making it possible to vary the color of the mixture as rapidly as possible during the application, especially in case of coupling of the mixture. distributor with an airbrush. According to one of its aspects, independently or in combination with the other aspects thereof, especially the foregoing, the subject of the invention is a dispensing system for a makeup product, comprising a dispenser receiving at least one two cartridges each having a reservoir containing a base product, the latter leaving the cartridge by an outlet channel of the cartridge, the outlet channel opening out of the dispenser or near its outer surface. The outlet channel can in particular result in a sampling zone of the mixture or in the vicinity thereof, in particular less than 5 mm, more preferably less than 3 mm, more preferably less than 1 mm, better flush. The cross section of the outlet channel is for example between 1 and 3 mm 2. Thus, each basic product from a cartridge can leave the dispenser without mixing with a base product of another cartridge and the dead volume can be minimized which can not be withdrawn and may increase the inertia of the system. The product is more readily available without having to flow through specific channels of the dispenser housing, avoiding a tedious purge step if cartridge change. The outside of the dispenser may be the sampling zone of the product, especially when the dispenser is made with a dish not intended to be removed, in which the mixture is dispensed, or an area of the dispenser for mounting a dispensing interface. removable output, which defines the sampling area. This output interface may include a cup as defined above. This mounting zone corresponds for example to the end of the distributor housing in the absence of the output interface. The mounting area may be substantially flat and perpendicular to the longitudinal axis of the dispenser housing. The dispenser may have three commodity cartridges. The dispenser may have housings for receiving the cartridges, which are preferably removably received in the dispenser. The latter may include passages for cartridges conduits defining the output channels. The length of these ducts is preferably such that the ducts are slightly recessed from the bottom or flush with the cavity for sampling the product, or alternatively slightly recessed or flush with the end face of the distributor housing. defining the mounting area. These cartridge ducts may be tips for driving pistons into displacement within the cartoculars, as detailed above.
[0039] Multiple exit interfaces There is a need to be able, with the aid of the same dispensing system, to easily make up different make-ups, and to be able, if desired, to make up areas as different as the skin, the lips or the eyelashes or eyebrows.
[0040] According to one of its aspects, independently or in combination with the other aspects thereof, and in particular the foregoing, the subject of the invention is a dispensing system comprising an assembly comprising a dispenser of at least one cosmetic product. , in particular makeup, and at least two output interfaces that can each mount removably on the distributor, these output interfaces for receiving the product or products delivered by the distributor, preferably being chosen from the following: - interface of outlet comprising a container, in particular a cup for sampling the product from the finger or with the aid of an applicator, - exit interface for delivering the product to a spraying system, in particular an airbrush, - exit interface comprising several receiving regions of the product, movable relative to the dispenser, - output interface for delivering the product to a nozzle e distribution.
[0041] Preferably, the assembly comprises at least three of said output interfaces, better the four output interfaces. The dispenser may comprise at least two different basic products and allow them to be dispensed in variable proportions, and preferably the dispenser has three different basic products and can deliver them in varying proportions. Each output interface may include a base for attachment to the distributor. This attachment can be made using screws for example, but preferably the base is arranged to allow disassembly and replacement of an output interface without the need for tools. This is for example a quarter turn fastener or with an external locking ring. The exit interface and / or the dispenser housing may include seals for sealing communication between the manifold housing and the exit interface. If necessary, the distributor is arranged to recognize the output interface which is mounted on it, for example by means of an identifier of the output interface in the form of specific reliefs, which are detected by the distributor, or of an electronic chip recognized by the distributor. This can make it possible to adapt the operation of the distributor to the output interface mounted on it. The distributor can communicate to a computer system information on the output interface that it carries, and the computer system can display according to this information a specific screen and / or launch a specific program for controlling the operating parameters of the distributor. , for example to adapt the dispensed dose and / or the flow rate to the nature of the output interface. Several output interfaces may initially be proposed to the user with a common distributor within the same package, for example a box or a carton box. The invention further relates to a makeup process, comprising the step of selecting an output interface, to mount it on the dispenser, and to deliver the product or products contained in the dispenser therein. Mapping and Learning The term "mapping" is understood here as a process of indexing a color and a zone, with registration.
[0042] Mapping may involve applications on areas smaller than one cm2. However, the naked eye then has difficulty in discerning whether the result obtained is adequate, and it is preferable to substitute the evaluation with the naked eye by an instrumented evaluation, with magnification. The application of small amounts of colored material can be done with the finger, with conventional tools such as brushes, or with specialized applicators.
[0043] Mapping can be generated during a learning period, during which the user performs tests with mixtures on different areas of the face; Once informed, mapping can then be used for everyday makeup. Specific graphical interfaces can be used during the learning period and during the period of use of the map. In particular, the distribution system can be used with a graphic interface where the operator sees the face, which is for example diagrammatic, figurative or precise as a photograph or a 3D simulation. In this case, the operator can point a part of the face on the screen to see appear and / or deliver the appropriate color. The graphic interface can also reveal other areas of the face where the use of the same color is adequate.
[0044] To carry out the mapping, the operator applies a color and then carries out the evaluation. The areas of the face can be treated one after the other; for example, the exercise is performed on part of the cheek, then on the nose, etc. .... Another possibility is to achieve a given mixture, and apply the same mixture to several areas. The operator must then look for the area of the face for which the color is suitable. The mixture is then indexed in the computer system by assigning it to the area or areas of the face for which it is appropriate. According to one of its aspects, independently or in combination with the other aspects thereof, and in particular the foregoing, the subject of the invention is a method of learning a distribution system comprising a dispenser making it possible to distribute a variable color mixture, and a computer system for selecting a color and storing data, comprising the steps of: a) selecting at least one color using an interface of the computer system, b) delivering to using the dispenser at least one mixture of the selected color, c) evaluating the mixture or mixtures distributed after application on at least one area of the face, d) storing the characteristics of at least one mixture, in particular a mixture that the user wishes to recall, and at least one area on which it has been tested. This memorization can be carried out especially with a view to subsequent distribution of this mixture to make up said zone. Preferably, the computer system is arranged to allow the user to signal whether the test result is satisfactory or not, or to provide information on the comparison to a test performed previously.
[0045] One can also make a given mixture, and look for the area of the face for which it is adapted. The mixture is then recorded by attributing it to the zone or zones of the face for which it is adapted, in a correspondence table which will be used thereafter, for, starting from an area of the skin, to deduce the mixture to be used. .
[0046] One can proceed in the same way with other mixtures to map the whole face and thus have a complete correspondence table of the face. It is also possible to make a given mixture, to apply it to a given area, then to vary the mixture until the most suitable mixture is obtained. The mixture is then recorded by attributing it to the zone or zones of the face for which it is appropriate, in a correspondence table which will be used thereafter, to, starting from an area of the skin, to deduce the mixture to be used. Preferably, the computer system evaluates and stores the quantities used zone by zone.
[0047] Such a method, by "test keys", identifies the product or products needed by the person who wants to wear makeup. Thus, the distribution system can be used at points of sale to advise people who want to wear makeup or at home to properly define the products to order. The interface of the computer system preferably comprises a touch screen displaying the color of the mixture during its selection. The interface can display a face and allow to inform the computer system by selecting the area on the displayed face. The computer system is preferably arranged to allow associating a zone, reconstitution parameters of the mixture, and the date of the test and / or any other identifier of the mixture. The computer system is preferably also arranged to allow to associate in addition to said zone, the reconstitution parameters of the mixture, and the date or the identifier of the mixture, at least one of the following data: the name of the the zone, the time of year, the name of an event, an identifier of the user, the age of the user. Steps a) to c) can be repeated at least once before storing the characteristics of the mixture in step d).
[0048] The computer system can be arranged to search a database for a commercial product reference, based on the characteristics of the mixture identified as being suitable for at least one given area, and to communicate it to the user. The selection in step a) can be done with the help of an expert system, external or not to the computer system. The expert system may analyze an image of the user to provide a blend color at least based on the scanned image. Step a) may be preceded by the proposal of a color and a test area with a mixture of this color, by the computer system to the user.
[0049] The computer system may be arranged to allow the user to inform him about the evaluation of the test result of step c) and to generate a proposed modification of the mixture to be selected when returning to step a). The computer system can be arranged to propose at least one color of mixture in step a) according to an application area entered by the user.
[0050] The computer system can be arranged to provide at least one application area in step a), according to a color filled in by the user. The dispenser can deliver in step b) at least two mixtures of different colors, preferably separate, for simultaneous application to the test area. This can save time and facilitate comparison of results.
[0051] The invention also relates to a makeup method using a dispensing system according to this aspect of the invention, wherein: a) The user sends a request concerning a makeup need to the computer system, b ) the latter generates a color proposal for the makeup of an associated area, on the basis of the previous learning, and c) the computer system controls the distributor for producing the mixture of the proposed color, especially if it is validated by the user. Such a method can use a mapping previously established with the user.
[0052] The invention further relates to a computer program product comprising code instructions which, when executed in a computer system, cause the computer system to: - Allow the user to select at least one color and / or an application area, in particular using an interface such as a touch screen, - controlling a dispenser so as to deliver a mixture of the color selected by the user, - allowing the user to trigger the storing the color of the mixture and an associated application zone, especially for subsequent distribution of the same mixture, especially on the same area. The computer program product may comprise code instructions which, when executed in a computer system, cause the computer system to: - Receive a request from the user concerning a need for make-up, in particular with the help of an interface such as a touch screen, - proposing on the basis of at least data generated by the learning method as defined above, at least one color and / or a zone of application, - controlling a distributor for the production of the mixture of the proposed color, especially if it is validated by the user. Remote assistance It is desirable to be able to help the user make-up, especially to choose the right colors. The invention, according to one of its aspects, independently or in combination with its other aspects, especially the foregoing, thus relates to a makeup process comprising the steps of: - enabling the establishment of a video link , for example via the internet, between a camera from a first site and a second site, - allow the second site to directly or indirectly control a distributor present on the first site, this distributor allowing to vary the color of a distributed mixture - Allow a person present at the first site to apply the distributed mixture and send to the second site a corresponding image, to receive in return information on the makeup result.
[0053] The second site may include a display screen that allows a counselor present in front of this screen to see the result of makeup with the product distributed by the distributor and to advise the person who has made up. This advisor can act in return on the distributor to change the color of the mixture and adapt it best to the face of the person on the first site. Thus, this person governs the mixture delivered by the distributor. The first person can wear makeup under the eyes of the second. The second person sees on his screen the result of the test, and thus can correct the mixture that it will control remotely, until the ideal makeup.
[0054] If necessary, the video acquisition can be calibrated using a test pattern, or with the mixture dispensed by the distributor on a reference surface. This allows a more faithful visualization of the make-up performed on the first site. Preferably, the video link between the two sites is a duplex link. The first site may receive a tutorial from the second site, if applicable.
[0055] Commodity identifiers may be provided at the second site; this can make it possible to know precisely the color of each of the basic products. The method may include storing the dispenser adjustment parameters once a given mixture is deemed satisfactory. Preferably, this storage can be controlled from the second site. The storage can take place in the computer system present on the first site and / or on an external server. An alternative may be to have a person work to help make up several people. This mode of implementation allows the development of "Make-Up Artists" and their work either within an institute or via the Internet. This also allows the makeup of people with limited means, such as the visually impaired, or poorly discerning colors, or elderly, or lacking self-confidence. Control by touch interface There is a need to facilitate the control of the distribution system and in particular the choice of the color of the mixture distributed. According to another of its aspects, independently or in combination with its other aspects, and in particular with the foregoing, the subject of the invention is thus a distribution system comprising a distributor and a computer system for controlling the dispenser, this computer system comprising a touch screen on which the color of the mixture can be displayed and a selection means movable on the screen, to vary the color of the mixture distributed. Preferably, the screen displays extreme colors between which the color of the mixture can be selected, by moving the selection means between these extreme colors. The screen can display a color scale between at least two colors, or a surface, in particular of triangular outline, within which the selection means can move. This surface may locally show the color of the mixture depending for example on the distance to each of the vertices, each materializing a pure basic product. The informative system can perform part of the calculations necessary to determine the fractions of each of the basic products leading to a mixture of the desired color.
[0056] The computer system can be a smart phone, a photophone, a tablet, a personal computer. Alternatively, it is integrated in the distributor housing. The computer system may have a camera. The latter can be used in particular for acquiring an image of the user and / or the mixture. The computer system can be arranged to display an image of a face, to facilitate the identification of the areas on which the mixture is to be applied. Coupling the dispensing system to a spraying means The dispensing system may comprise or be connected to a spraying means of the mixture, preferably an airbrush. The invention aims, in another of its aspects, to further improve the distribution systems comprising a spray system, preferably an airbrush, and has for its object, in one of its aspects, independently or in combination with the others aspects, and in particular the above, an assembly comprising: - Spraying means, preferably an airbrush comprising a sampling chamber subjected to a driving air stream, - a dispenser comprising at least two compartments containing products of different products, the products being delivered by means of spraying preferably through separate dispensing orifices.
[0057] The dispenser may have three cartridges containing makeup products of different colors. The airbrush may include a stylet defining the sample chamber, the stylet attaching to the dispenser or an output interface attached to the dispenser, or integral to this output interface. The dispensing system may comprise a circuit for controlling the operation of the dispenser, making it possible to vary the proportion of the basic products dispensed in the sampling chamber, during the operation of the airbrush. Proportions can be modified depending on the movement of the airbrush relative to the surface on which the mixture is sprayed. This displacement can be mechanized, if necessary. This control circuit may comprise or consist of a computer system as defined above. The dispenser housing can be used as a handle when handling the assembly to dispense the mixture. The dispenser may include a camera and / or one or more sensors such as accelerometers to automatically locate the area on which the mixture is applied, and to be able to automatically adjust the color according to the position, if any.
[0058] The invention also relates to a makeup process using an assembly as defined above, in which a mixture is sprayed on the skin using the spraying means, in particular the airbrush. The composition of the mixture may be modified during movement of the airbrush relative to the skin. A gradient can be realized.
[0059] This aspect of the invention is based on the observation that the dispenser can be used to supply the spray system, in particular the airbrush, while allowing the dispensing system to be sufficiently reactive to allow a change in the color of the dispensed mixture. during facial makeup, especially when the makeup area changes.
[0060] It may be advantageous for the distribution of the products to be iterative, in particular with non-out-of-phase distribution times between the different products.
[0061] This may make it easier to vary the composition of the mixture dispensed over time. The mixture can be made directly in the airbrush, with virtually no annoying dead volume, thus changing the pulverized mixture in real time.
[0062] The depression created in the sampling chamber is sufficient to drive the basic products without interfering with the dosage. The depression prevailing in the sampling chamber is for example between 10 mbar and 200 mbar. The viscosity of the base products measured at 1 atm and 25 ° C with a CONTRAVES TV rotary viscometer equipped with a mobile MS-r3 or MS-r4 at the frequency of 60 Hz, after 10 minutes of rotation of the mobile, is for example between 0.05 Pa. S and 50 Pa.S The section of the arrival channels of the basic products in the chamber is, for example, between 1 and 3 mm 2. The supply of product is preferably carried out continuously. It is still possible to simultaneously apply immiscible or reactive base products, such as an aqueous gel and an oily gel, which will be deposited in a pixellated manner directly on the skin, producing a kind of gel / gel in situ, silicones reactive, or coloring products that react together. Commodity ratios can be adjusted according to the particular desired result. For example, in the case of aqueous gels and oily gels, the ratio of 10/1 to 1/10 can be varied. Location or self-location system The distribution system according to the invention may have a location or self-location system. Locating system is a means of grasping, on the part of the person, the area that he is going to treat. This can be achieved in particular by systems leaving free at least one hand. Thus, it is possible to use an interface of a computer system such as a touch screen, a joystick, or a voice recognition system. A self-locating system is a means of grasping, without the person intervening, the area to be treated. This can be achieved by one or more accelerometers which, by virtue of the movements, deduce the directions that the person is aiming for or by a camera and an image recognition system.

The dispensing system 10, according to the invention, shown in FIGS. 1 and 2, comprises a distributor 11 which is provided in the upper part with an exit interface 110 through which the dispensing of a cosmetic formulation product takes place. customized. The dispenser 11 can be manipulated with one hand. Its length, excluding output interface, is for example between 140 and 160 mm and its diameter between 40 and 60 5 mm. The dispensing system 10 may comprise, as illustrated, an actuating means for controlling the dispensing, for example a push-button 12. When the user presses the push-button 12, the dispenser 11 delivers the product from information that was previously communicated to him by a computer system, for example using a wireless transmission, as will be detailed below. The operation of the push button 12 can be programmed from an interface of the computer system, so as to continuously deliver the mixture as long as pressure is exerted, or to deliver only a predefined dose, regardless of the duration during which the user supports on the push button. As can be seen in particular in FIG. 4, the dispenser 11 houses several cartridges 30 each containing a base product, the dispenser 11 making it possible to determine the quantity of each of the basic products which is dispensed so as to obtain, after mixing the distributed doses. a product with the desired properties. Each of the cartridges 30 can be introduced into the housing of the distributor 11 from the rear, as illustrated in FIG. 2. In the example considered, the dispenser 11 receives three cartridges 30, but the invention also extends to the case where the number of cartridges 30 is different. In particular, certain aspects of the invention also apply to the case of a single cartridge received in the dispenser housing. FIG. 5 shows a cartridge 30. It comprises a body 31 in which a piston 32 can be displaced along the longitudinal axis X of the cartridge so as to reduce the volume of a reservoir 33 located under the piston 32, containing the corresponding basic product. The volume of the reservoir is preferably between 2 and 5 mL, being for example of the order of 3 mL. The piston 32 is driven in X-axis displacement by an externally threaded hollow rod 34, engaging a corresponding thread through the piston 32.
[0064] The rod 34 defines a channel through which the product contained in the reservoir 33 can circulate when the piston 32 moves in the body 31 in the direction of a decrease in the volume of the reservoir 33. The rod 34 is driven in rotation around the X axis by a head 36 which can rotate relative to the body 31, and communicates with a cannula 37. Each cartridge 30 is mounted in the distributor 11 with a support piece 40, which is shown separately in Figure 8, which comprises an axially slotted clamping sleeve 41 on which a locking ring 43 can slide, as can be seen in FIG. 4. When a cartridge 30 is put in place, the support piece 40 is engaged thereon, the opposite side to the cannula 37, and the locking ring 43 moved on the sleeve 41 to clamp the support member 40 on the body 31. The support member 40 immobilizes the cartridge 30 in the housing of the distributor 11. The head 36 of the cartridge 30, presenting the cannula 37, is capped by a drive part 50, shown in isolation in FIG. 7, which tightens the head 36 so as to be able to turn about the axis X with it. When the drive part 50 is rotated about the X axis, its rotation is transmitted to the head 36, which can rotate relative to the body 31 and drive with it in rotation the rod 34. The friction force of the piston 30 on the inner surface of the body 31 is sufficient so that the piston 32 does not rotate relative to the body 31, so that the relative rotation of the rod 34 and the piston 32 causes the displacement of the latter along the axis X. This displacement is accompanied by a decrease in the volume of the reservoir 33 and a rise of the base product contained in the cartridge 30 by the rod 34, then in the cannula 37.
[0065] The drive part 50 comprises an internal channel 52 fed by the cannula 37 and which opens out through a dispensing orifice 53. This channel 52 is formed by a nozzle 36. The drive piece 50 has a skirt mounting 54 which axially covers the head 36 of the cartridge 30. This mounting skirt 54 is connected by a transverse wall 55 to the endpiece 56.
[0066] The tip 56 has reliefs 57 allowing its coupling in rotation with a toothed wheel 60, visible in particular in Figure 9, belonging to a drive mechanism of the distributor housing 11.
[0067] In the example under consideration, the reliefs 57 are in the form of two diametrically opposed lugs protruding on the endpiece 56 at its base, which engage in corresponding notches of the toothed wheel 60. The endpiece 56 has a narrowed portion which has a groove hosting an O-ring 58. The narrowed portion is connected by a shoulder 59 to the rest of the tip. The head 36 of the cartridge 30 may carry an O-ring which provides a tight coupling between the cannula 37 and the drive part 50. The drive mechanism comprises electric motors 70, equipped with reducers 71, visible in particular in FIG. 10. The output shaft of these gearboxes is coupled to a driving wheel 72 which meshes with the toothed wheel 60. In the example in question, the longitudinal X axes of each of the cartridges 30 are arranged at 120 ° relative to each other. other, around the longitudinal axis Y of the distributor housing 11. The motors 70 are arranged between the cartridges 30, the axes of rotation of the motors being also arranged at 120 ° from each other about the Y axis of the distributor 11 In this way, a compact construction of the distributor 11 is obtained. The geared motors advantageously have a torque greater than 70nN.m. For example, a Maxon 118392 reference motor is used, associated with the Maxon 218418 planetary gearbox. Such a motor has a diameter of 10 mm, a power of 1.5 W, a nominal voltage of 3 V, an idle speed of 1300 rpm and a maximum torque. 1.5 mNm. The gearbox has a diameter of 10 mm, an absolute reduction of 256/1 and a torque of 0.2 Nm. An electronic circuit 81, shown in isolation in FIG. 11, is present in the vicinity of the upper end of the distributor housing 11. This electronic circuit 81 comprises a card 80 which is traversed by passages 83 for the output axes of the gearboxes 71, as well as openings 82 for the narrowed portions 55 of the drive endpieces 56. Sleeves 82a can be fixed on the card 80 to barrier against possible product leaks to the card 80. The end pieces 56 pass through the sleeves 82a, preferably with a small clearance. The card 80 carries the pushbutton 12 above and supports a number output pins 86 for powering the motors 70.
[0068] The electronic circuit 81 comprises a microcontroller or the like making it possible to control the various motors 70, in order to distribute the desired quantity of each of the basic products. The delivery resolution of the base products is for example between 0.001 and 0.003 ml, being for example of the order of 0.0025 ml.
[0069] The distributor housing 11 also houses a battery whose accumulators 89 are advantageously located as can be seen in FIG. 4, each in the extension of a motor 70. Preferably, as shown in FIG. It is performed using a computer system 100 such as a portable terminal, for example a smartphone, a tablet for example brand "Ipad" or a personal computer. The transmission of the control information of the distributor 11 by the terminal 100 is preferably wireless, for example by a Bluetooth connection. In a particular example, the electronic card 81 makes it possible to manage the following points: calculation of the volume of each product to be delivered according to the volume fraction instruction of each product, the operating mode (continuous, dose or purge), the value of the flow rate or the volume, - measurement of the power supply currents of the motors 70, - Bluetooth communication with the computer system 100, - management of the button 12 for delivering the products, - management of the on / off switch, - management the LED display (s), - battery charge.
[0070] The card 80 comprises, for example, the following components: - Texas Instrument CC2541 microcontroller, - Blue CMS led to give status information to the user, - Protective thermal fuse, - 32 MHz quartz, - On / Off switch The Texas Instruments CC2541 microcontroller incorporates a 256 kB RAM programmable flash memory as well as many features. This microcontroller can be programmed in C, in the JAR Embedded Workbench environment. The outlet ports 53 of the cartridges 30 open substantially at the upper end of the distributor housing 11, as can be seen in Figure 13 in particular. The upper face 14 of the distributor housing 11 defines a receiving surface for mounting an output interface which channels the products from the cartridges to a sampling or dispensing area. In the example of Figure 1, this output interface 110 is in the form of an insert, which is shown in isolation in Figure 14, which has at its periphery as illustrated passages 111 for screws The output interface 110 defines in this example a cup 115 in the bottom of which open out feed ports 116, each communicating via an internal channel to the output interface. 110 with a respective output port 53.
[0071] Thus, in the example considered, the basic products contained in the cartridges 30 can be distributed to the cup 115 without mixing. When using the dispenser 11, the user can fill the cup 115 with predefined proportions of each of the basic products, as illustrated in FIG. 3, then can take the product present in the cup 115 in order to apply it. . This sampling can be performed for example on the finger, as illustrated, or with any suitable cosmetic applicator. The cup 115 is preferably shallow, which facilitates cleaning, and diameter sufficiently large not to hinder access to the product. The depth p of the cup 115 is thus preferably between 1 and 5 mm and its diameter d or that of the circumscribed circle when the crucible contour is not circular, is preferably between 20 and 50 mm. It is preferably 4 dlp 50. The feed orifices 116 are preferably of less than 3mm diameter for example of the order of 1 mm. The output interface 110 can receive a closure cover 118 of the cup 115, to prevent the product from drying or being exposed to soiling in the absence of use. This cover 118 is preferably made of transparent plastic material and can be fixed by friction, screwing or snapping on the upright of the cup 115, or more generally at any suitable place on the output interface 110.
[0072] The maximum capacity of the cup 115 is preferably between 0.02 and 0.25 ml. Preferably, the volume defined by the volumes of the internal channels of the output interface 110 between the input therein from the supply ports 53 to the supply ports 116 is less than or equal to 0.4m1. . The housing of the distributor 11, in its configuration illustrated in FIG. 13, that is to say without the output interface 110 described above, has the advantage of being able to be coupled to various forms of other interfaces of FIG. output, depending on the makeup that is desired and / or the area to be treated.
[0073] Thus, there is shown in Figure 15 an alternative output interface 110 having a dispensing nozzle 150, oriented generally along an axis Z which extends obliquely with respect to the longitudinal axis Y of the distributor 11. Three internal channels respectively communicate with the outlets 53 of the different cartridges 30 and open at the end of the tip 150. The output interface 110 can be mounted at one end of the housing of the distributor 11, as shown in Figure 15A. In the variant of Figure 16, the output interface 110 comprises three cannulas 160 which communicate respectively with the outlet ports 53. These cannulas 160 are grouped in the center of the output interface 110, which allows mounting on those for example a tip 170 for applying the product on the eyelashes, as shown in FIG. 25, with a porous tip 180 for application to the lips, as illustrated in FIG. 27, or a flocked tip 190 such as a felt tip, as shown in Figure 28. In the case of the tip 170 of Figure 25, it comprises for example, as shown, striations 171 transverse, between which open out product feed ports. The mixture of the different basic products can take place inside the nozzle 170, thanks to an integrated static mixer, for example. The tip 180 comprises for example an open cell foam part, having the shape of the lips. The mixture of the basic products can be made within an internal conduit of the nozzle 180. The nozzle 190 may comprise a porous application member 191, the end of a rod 192, connecting to a base 193 for mounting on the rest of the output interface of Figure 16.
[0074] FIG. 16A schematically illustrates the possibility of having as outlet interface 110 a cup 115 having passages 115a for outlet ducts 30a of the cartridges, including when these ducts are used for rotational driving. Threaded rods for moving the pistons. The length of the conduits 30a is such that they open into the bottom 115b of the cup or near its bottom, without projecting therein. Preferably, the internal section of the conduits 30a is small, to minimize the dead volume. In the example of FIGS. 22 to 24, the output interface 110 comprises a tip 200 which is oriented generally obliquely with respect to the longitudinal axis Y of the distributor. This tip 200 is traversed by internal channels 210, respectively communicating with the outlet ports 53 of the base products from the cartridges 30. The output interface 110 has a mounting portion 215 which allows the attachment on the output interface 110 of an airbrush 220, as shown in Figure 24. The tip 200 is fixed in place of the usual tank of the airbrush and the channels 210 open into the nozzle of the airbrush where they are subject to the depression created by the speed of the drive airflow. A clamp is formed by two uprights 216, to receive the body of the stylet of the airbrush 220, and ensure its maintenance snap. Preferably, the orientation of the tip 200 is such that it allows the spraying axis to be oriented substantially perpendicular to the longitudinal axis of the dispenser housing 11. It can then be used as a handle to manipulate the airbrush.
[0075] The outlet orifices 210 are advantageously very close together, being separated by thin internal partitions of the end piece 200. Preferably, the section of each of the outlet orifices is less than or equal to 3 mm 2 over a length of at least 5 mm. . It is also possible to provide the distributor housing 11 at the top with a support movable relative to the housing, for example in the form of a turret 250, as shown in FIG.
[0076] This turret 250 rotates for example around an axis of rotation which coincides with the longitudinal axis Y of the distributor. The turret 250 may comprise a plurality of housings 255 which can each accommodate the products delivered by the distributor 11 in a corresponding filling position. To successively fill the different housings, the turret 250 is rotated, for example by a quarter turn, each time. The presence of several housings 255 can make it possible to distribute products of different formulations, from different basic products, for example to vary the shade of the products present in the different housing 255.
[0077] FIG. 29C illustrates a support having housings disposed thereon substantially like the different zones of a face; each housing may contain a mixture whose color is adapted to the corresponding part of the face. Thus, it is easy for the user to know where to apply the mixture taken from a given dwelling. The dispenser 11 can be used to deliver a mixture whose formulation changes over time and collect the mixture in a container movable with respect to the dispenser, so that the mixture is deposited at a location of the container which varies with time, to make a gradient. For example, as illustrated in FIGS. 29A and 29B, the dispensing system includes an exit interface 110 having a stationary portion relative to the dispenser and a movable portion 252 having a housing 253 for receiving the mixture. For example, the dispenser 11 is disposed in this case with the cartridge outlets downwards, and equipped with a mixer, so that the mixture falls under the effect of its weight in the housing 253. An engine can move the movable portion of the output interface relative to the dispenser, in a manner synchronized with the variation of the characteristics of the mixture, so that a gradient is obtained along the housing 253, as shown in Figure 29B. The dispensing system may include a pedestal 254 that holds the dispenser upside down. The output interface 110, especially when it comprises a cup, may comprise a static mixer which ensures the mixing of the basic products. FIGS. 17 to 21 show an output interface 110 comprising such a static mixer.
[0078] This output interface 110 may comprise an outer body 260 which is fixed on the housing of the distributor 11 and which has an outer tubular upright 270. The body 260 comprises channels 261 for the admission of the different basic products. These channels 261 open into a central chamber 262, delimited by an inner tubular upright 263. This upright 263 is traversed by an opening 264 which opens into an annular space 265, between the inner upright 263 and the outer upright 270. A mixer core static 280, shown in isolation in Figure 20, is disposed in this space 265.
[0079] The central chamber 262 can communicate with a peripheral chamber having a series of partitions formed by the core of the mixer and which act as baffles for mixing, and create a shear thereof. The peripheral chamber may comprise a perforated annular partition 284 defining openings 285, one of which is visible in FIG. 21, through which the mixture passes while circulating in the peripheral chamber. The central and peripheral chambers can be closed superiorly by a wall 286 which defines the bottom of the cavity receiving the mixture. The bottom 287 of the peripheral chamber may be helical in shape and decreasing in height as one progresses towards the exit. The latter can lead forward a ramp 288 connecting the bottom 287 of the peripheral chamber and the upper wall 286 of the mixer, this connecting ramp being preferably a helical portion extending the helix formed by the wall of bottom of the peripheral chamber. Preferably the peripheral chamber comprises the aforementioned annular partition and radial partitions 281 which force the mixture to circulate alternately between upper and lower regions of the peripheral chamber and between radially inner and outer regions, the mixture circulating for example from a region upper and radially outer to a lower and radially outer region passing through the aforementioned annular partition.
[0080] The body 260 radially closes the peripheral chamber. The outer body 260 of the mixer and the core 280 of the mixer can each be made in one piece by injection molding.
[0081] The product gains the core 280 of the static mixer through the passage 264, then flows between the uprights 263 and 270 over substantially a complete circumference, to the exit 282. The numerous baffles imposed by the partitions 281 cause an intimate mixing of the components introduced. in the output interface 110. The resulting mixture can be picked up by the user in the housing 283, above the static mixer. As indicated above, the distribution system 10 according to the invention preferably comprises a human-machine interface which enables the user to drive the dispenser 11 easily and intuitively. This interface can belong to a computer system 100 which communicates with the computer. Distributor 11. FIGS. 31 to 37 show various examples of tactile interfaces that can enable the user to choose the color of the mixture resulting from the metered distribution of the various basic products.
[0082] This interface may have, as illustrated in Figure 31, a color selection area, for example in the form of a triangle whose vertices correspond to the colors of each of the basic products contained in the cartridges. The user can move a cursor 300, for example in the form of a ball, relative to the vertices A, B and C of the triangle.
[0083] The closer it gets the cursor 300 to one of the vertices, the larger the fraction of the corresponding basic product in relation to the total quantity of the different products distributed. The fraction of each product in relation to the total amount can be indicated at 301 by a numerical value on the interface.
[0084] The interface may allow the user to increment or decrease the quantity of each of the products, for example by acting on control buttons 302, which allow a precise adjustment of the quantity of each of the basic products. The surface of the triangle 310 may have a color that varies locally so as to be representative at each point of the color of the mixture resulting from the weighting of the different basic products in proportions corresponding to the relative coordinates at this point.
[0085] The interface may include a button 305 for accessing a specific product volume adjustment menu that is dispensed to purge the dispenser. The interface can also advantageously allow an adjustment of the product flow through buttons 304 and 306 to a specific menu for setting the flow. In the example considered, the interface offers the choice between a continuous distribution mode, through the button 304, where the products are distributed as the user presses the control button 12. The corresponding dose can be transmitted to the user. interface and displayed.
[0086] The button 306 makes it possible to select an operation in dose mode, in which a very brief press on the button 12 triggers the dispensing of a predefined dose. To vary the flow, the distributor acts for example on the duty cycle of motors.
[0087] The interface can be arranged to allow the user to program or memorize the settings that are his preference, through a menu 307 access to favorites. The touch interface illustrated in FIG. 32 shows on the screen three colored zones 400, each corresponding to the color of one of the basic products contained in the dispenser 10, and a central zone 410 showing the color of the mixture. resulting. The relative quantity of each of the basic products can be adjusted by means of sliders 415 which move for example on lines joining each of the zones 400 to the central zone 410.
[0088] During the use of the interface, it can memorize a given setting and display on the screen a button 420 of the color of the mixture. The user can then, by simply pressing this button 420, distribute a mixture of the corresponding color. In the example of FIG. 34, the interface displays in a zone 500 a given hue, and proposes to the user, by means of control buttons 510 each of the color of the corresponding basic product, to increase or reduce the proportion of this base product in the final mixture. The color of the area 500 is recalculated according to the actions on the control buttons 510. In the variant of Figure 35, the interface shows a color chart having several areas 530 each corresponding to a particular proportion of different commodities. The user can select one of these areas, for example by pressing on it with his finger. The interface may be arranged to display the selected color at a larger scale in area 535. The programming of the dispenser 11 to distribute this color is for example triggered by pressing the zone. In the example of Figure 36, the user can move on a continuous color chart 550 a cursor 555, which shows in a zone 558 the selected color. The user can then, by pressing for example in the area 556, trigger the sending to the distributor 11 of the instructions necessary for it to distribute a product of the selected color. It can be seen in FIG. 37 that the interface can memorize the various selected shades, and then make them appear on the screen so as to allow the user, by pressing corresponding buttons 560, to select again very easily a shade previously chosen.
[0089] FIG. 38 shows an example of a user interface 1000 of a distribution system comprising a distributor, preferably as described above, and a computer system 100 to which the interface belongs. The computer system here comprises for example a device such as a laptop, a tablet or a smartphone, operating independently or connected to a remote server. In the example considered, the interface 1000 is defined by the touch screen of such a device. In a variant not shown, the dispenser incorporates a touch screen or any other type of human machine interface, and can be used without connection to another device.
[0090] The device executes an application, which has for example been downloaded beforehand, and which displays on the screen a face 1035 and a series of buttons allowing the user to enter information.
[0091] The face may have multiple zones Z1 to Z6 that can be touched, for example the forehead, the nose, the cheeks, the eyelids, the chin, and the lips. The buttons on the screen may allow for example to enter the name of the makeup or the user, to display the selected area, to choose the color, and inform the computer system of the acceptable or unacceptable result of the test performed or even as illustrated to give information concerning the evaluation of the result relative to a test performed previously, namely for example better or "less well". The screen can also display a button to memorize the choice of a color and a zone, after having made a test with this color on the zone in question. The choice of the color is carried out for example with a color scale similar to that described with reference to FIG. 36. The computer system is arranged to store the data in the form of a correspondence table for example, so as to associate with a facial area parameters allowing to reproduce the mixture distributed during the test. These parameters comprise, for example, the relative contents of each of the distributor's basic products in the mixture, the quantity Q distributed, as well as additional data such as, for example, the name of the zone, the date of distribution of the mixture and / or any other identifier of the mixture, the identifiers of the basic products, the period of the year, in particular the season, the age of the user, his sex, his name or surname, the name of an event associated with makeup, by example a birthday, among other data, the amount of product adequate for the area. The ancillary data may allow the user to reproduce more easily makeup that he considered adequate for a period of the year, or recalling a life event, or to give a rejuvenating effect. This data may be stored in the computer system 100, for example in the aforementioned apparatus and / or on a remote server with which the apparatus communicates, or in an integrated electronic memory to the distributor 11. Thus, according to the invention, the user can cause the dispenser to deliver a first colored material, to apply it to a first zone of the face, then to judge it adequate or not. If the result is satisfactory, the user can register it by indexing it to the zone; if the result is unsatisfactory, the user can order a new color to repeat the above operations. The computer system can be used in this context in a variety of ways. For example, as illustrated in FIG. 40, the user selected at a step 1010 a color to be tested, for example by using the color scale 1011 appearing on the screen, by moving the adjustment knob 1012. The choice of color is transmitted to the distributor 11 in step 1015. For example, the apparatus transmits the quantities to be dispensed from each of the basic products, and the electronic circuit 81 is responsible for controlling the motors accordingly.
[0092] In step 1016, the user presses the control button 12 of the dispenser 11, which causes for example the dispensing of a dose of the mixture, the color selected by the user. For example, the mixture is dispensed into the cup 115, then removed and applied by the user to the cheeks or any other zone indicated on the interface, at step 1020. In variants, the product is applied using an airbrush or by any other means as described above. The user then enters at step 1022 the computer system using the buttons 1021, on the result.
[0093] If the user indicates that the result is satisfactory, the system proposes for example to validate with a button the parameters of the test to store them in step 1031. If the result is not satisfactory to the user and indicated as such with the aid of the button 1032, the result can nevertheless be automatically saved in step 1034. It is thus possible to index to each zone not only the appropriate color or colors but also the one or more colors that do not go at all to this area. The user can then retest on the same area by returning to step 1010.
[0094] If the user was satisfied with the result, he may also wish to retest, for example on a different area of the face.
[0095] If this is the case, if the user is not satisfied, the interface may suggest to him whether the result is better or worse than the previous test, using corresponding buttons 1040 and 1041. In In this case, the computer system can be arranged to determine whether, in view of the information entered by the user, a proposal can be automatically made as to the choice of the new color to be tested. If necessary, a questionnaire can be displayed to help the computer system to propose a color based on the tests performed and the evaluation made by the user or by a professional who assists him.
[0096] For example, if the color is judged as "unsuitable", the system may receive additional information from the user, for example "too light", which will help him to propose a new color more in line with what is expected the user. It may be interesting for the computer system to be able to receive comparison information of the result compared to the previous tests, for example "it's better" or "it's not so good" and from there, the system is able to deduce the new color to propose. Another option is that the computer system can receive comparison information relative to a target, for example "it's almost ideal" and from there, the system is able to automatically adjust its color changes.
[0097] In this case, if it receives the information that the desired result is nearly achieved, the system can adopt small levels of color change and review the color scale accordingly. In the case where the distribution system itself proposes the colored mixtures to be tested, it can be based on pre-programmed test scenarios and modify the follow-up of the scenario according to the successes or failures of the evaluation. Thus, for example, if from the third product application, it receives information that the color is almost ideal for the user, the dispensing system can leave the program and then be guided by the instructions of the operator . In general, the user can be helped by an expert system in the choice of colors to try. This expert system is for example a program executed on the device with which the distributor communicates or on the distributor itself, which is based on answers to a questionnaire and / or on measurements, for example of the color of the skin , performed by a specific sensor or a camera. The user can thus be assisted by an instrumented evaluation, for example a color sensor. The expert system can still be implemented on a remote server with which the device or the distributor exchanges information. The operator can still send an image of his face to a specialist who can preprogram the choice of starting colors. In another example of implementation, the user presents the computer system with a picture of his face, and the computer system is arranged to analyze it and create a program defining the areas to be tested and the first products to be delivered, to the times in color and quantity. For example, the computer system may be arranged to automatically select makeup colors to be offered to the user by acquiring a photograph at step 1070, as shown in FIG. 42. For example, the apparatus who communicates with the distributor 11 is equipped with a camera, and the user takes a photograph of his face. The image is then analyzed at step 1071, and colors are provided for each face area at step 1072, according to, for example, predefined color matching rules. The dispensing system can be user oriented to decide the color but also the quantity of product to be delivered. For example, the user may indicate "nose" or "stain" and the dispensing system is arranged to adapt the dispensed dose according to a mapping in memory of the doses to be dispensed according to the areas to be treated. The computer system can guide the user in the choice of the colors of the mixture to be tried, in order to limit the number of necessary tests until obtaining a pleasant result for the user. It is thus possible, as illustrated in FIG. 41, that after the application of a mixture delivered by the dispenser on a given area of the face at step 1060, the computer system asks the user whether the result is satisfactory or not, and performs itself, if the result is considered unsatisfactory, a change 1061 of the parameters of the distributor so as to modify the mixture distributed. The user then only has to make a new test with the modified mixture.
[0098] When a mixture is reported to be satisfactory, the computer system can memorize the corresponding parameters to allow the mixture to be recreated later.
[0099] The system can then repeat the previous steps for a new application area. In successive trials, the operator does not need to treat the entire face. It can for example choose between 3 and 8 areas of small areas, for example 5 areas. The distribution system is then advantageously provided for interpolating and / or extrapolating the data concerning the colors considered to be adequate, in order to calculate the colors which should be considered as adequate on areas on which the exercise has not been done. At the end of the training, the system can generate a visualization of the appropriate colors on the different zones, tested or calculated. The distribution system can be arranged to signal whether certain colors appear aberrant, relying on this to compare against typical maps in memory. Thus, he can propose to the user to redo all or part of the mapping exercise.
[0100] Once the computer system has been learned, that is to say that colors of mixtures have been identified as being suitable for the user to make up certain areas, the user who wishes to wear makeup has only to recall the zone to be made up, in step 1080 of FIG. 43, and the system can automatically propose to the user at step 1081 a suitable mixing color.
[0101] In the variant illustrated in FIG. 44, the user selects a color at step 1090 and the computer system proposes at step 1091 an area to apply a mixture of this color, based on previously collected information on the color. basis of the tests carried out. The proposed area is for example the one where an identical or similar color has already been applied and the result deemed acceptable by the user. FIG. 46 illustrates an exemplary implementation of the invention, where after having carried out tests on different zones at the step 2010, the user indicates to the system the mixture or mixtures which he estimates to obtain the best result, which allows the system to know the corresponding parameters in step 2012. Then, in step 2014, the system can offer the user references of commercial products having the same properties or similar properties.
[0102] In an alternative, the system sends to a remote manufacturing center the parameters for producing a composition of the same formulation or having the same properties as the mixture that the user has tested and found satisfactory. FIG. 45 illustrates the possibility of dispensing with the distributor several doses 2020a to 2020d of different mixtures, juxtaposed on a support 2021, so as to allow their application to distinct regions adjacent to the same zone. The user can at once apply a series of colors to quickly identify the appropriate color. The colored materials present on the support 2021 may have been chosen by the operator himself or proposed by the distribution system.
[0103] The support 2021 is for example movable relative to the dispenser housing and moved sequentially to deposit the corresponding mixtures in the different zones 2020a to 2020d, being for example similar to the supports described with reference to FIGS. 29 or 29A. The user can then easily compare the results between the different regions, and report to the system the mixture producing the best effect.
[0104] FIG. 47 illustrates a system that makes it possible to help the user to make up, in particular to choose the right colors. This system makes it possible to establish a video link, for example via the Internet, between a camera 2060 of a first site 2061 and a second site 2062. The camera 2060 is for example integrated with a tablet or smartphone which constitutes the computer system 100. The second site 2062 is allowed to drive directly or indirectly the distributor 11 present on the first site 2061. Thus, the person present at the first site can apply the distributed mixture and send to the second site 2062 a corresponding image, for receive feedback on the makeup result. The second site 2062 may include a display screen 2064 which allows a counselor present in front of this screen to see the result of makeup with the mixture dispensed by the distributor and to advise the person who has made up. This advisor can act in return on the distributor 11 to change the color of the mixture and adapt it to the face of the person on the first site. The protocol for exchanging data between the two sites thus makes it possible to send command instructions to the distributor 11, either directly or via the computer system 100 present on the first site. Thus, the person on the second site governs the mixture delivered by the distributor 11. The first person can wear makeup under the eyes of the second. The second person sees on his screen the result of the test, and thus can correct the mixture that it will control remotely, until the ideal makeup. Preferably, the video link between the two sites is a duplex link, so that the user on the first site can see the image of the advisor on the computer system screen. The latter can send the user present on the first site a tutorial, if necessary.
[0105] The memorization of the control parameters of the distributor 11, once a given mixture is deemed satisfactory, can be controlled from the second site. Advantageously, the dispensing system 10 is arranged to be able to aesthetically modify the set of colors for each zone if the person wishes to change the color of his face. The dispensing system can be arranged in such a way that it is sufficient for the user to change a single color in one area to modify all others. The distribution system can use for this translations, for example by raising the color saturation or shifting the hue. The distribution system can be arranged to receive the mapping of someone else, real or virtual. It can also combine the mapping of the person 20 with the cartography of another, to sublimate the makeup without losing the characteristics. The interface can be used to define makeup programs where the order of the areas to be made up or the order of the colors to be proposed are defined. EXAMPLES A dispenser 11 such as that illustrated in FIG. 3 is made. The dispenser is arranged to communicate with a tablet 100 such as an Ipad. This computer system runs an application called "p.Mix" developed in the specific environment of Apple (XCode 4 and Simulator i0S) in Objective C language. It uses basic frameworks Foundation, UIKit and CoreGraphics, providing the 30 tools of manipulation of data structures, calculation tools and features related to the graphical user interface.
[0106] The application also uses the CoreBluetooth framework providing access to Bluetoth 4 Low Energy devices with the following main tasks: - Search for Bluetooth 4.0 Low Energy devices, - Connection / disconnection and management of connection parameters, - Communication in read mode and / or writing based on the GATT (Generic Attribute Profile) architecture. The application proposes the following functionalities: - Definition of the fractions of basic products, - Choice of the mode of operation when the pressing on the control button 12, namely continuous, purge or dose, - Display of a triangle of volume fraction as shown in figure 30 with volume fraction management by tactile touch on the triangle or by the + / associated buttons for each product, - Bluetooth connection / disconnection and real-time transfer of the instructions to the distributor, - Settings of the flow rates in continuous mode, and quantity in dose mode, - Calculation, display and transfer to the distributor of the volume fractions of the products in real time, according to the set point, with the sum of the fractions always equal to 100%, - Recovery and displaying the couples of the three motors in real time, and - Saving the main parameters in a configuration file. Continuous mode is a distribution mode where the mixture of the three basic products is dispensed as long as the user presses the dispense button 12. The product is delivered with a rate of which an estimate is displayed above the button 304 Continued ". The choice of flow is made in a "Settings" menu. The "dose" mode is a mode of distribution of the mixture per dose, where the dose is delivered following a user pulse on the dispensing button 12. A pulse is sufficient and the user can then release the button. The overall dose of the product dispensed is that indicated above the button 306 "Dose", 0.1 ml for example. This volume can be changed in the "Settings" menu. The "purge" mode is a dispensing mode where a dose of mixture with equal volume fractions (33%) is delivered as soon as the user has pressed the dispensing button 12, as in the "Dose" mode. One pulse is enough and the user can then release the button. When the dose has been fully distributed, the button can be released. If you release before the end, the distribution stops, even if the specified volume is not reached. The overall dose of dispensed product is that indicated above a 305 "Purge" button, for example 3 ml. This volume can be changed in the Settings menu. The user determines the desired color with the application that runs on the tablet and calculates the fractions of different products. The tablet communicates this value to the distributor via Bluetooth connection.
[0107] The electronics integrated in the dispenser 11 retrieves the information and automatically adjusts the flow rates of the three cartridges so as to obtain a mixture of the desired color. When the user wants to use the product, he presses the button 12 of the dispenser to get the product out. He presses as long as he wants the product, in "continuous" mode. In "dose" mode, the user presses button 12 once and the preset dose is delivered. The distribution can be continuous, that is to say, the motors operate continuously, the entire volume being distributed in one go, or iteratively, the motors then operating in a pulsating manner; in this case, the time interval between two pulses makes it possible to vary the flow rate. Small volumes are delivered one after another in several steps. The pulses can be separated for example by intervals of 50 ms, 100 ms or 200 ms. The duration of a pulse during which the motor rotates is for example 50 to 150 ms.
[0108] The main page of the application "[iMix" includes in this example the following elements, as can be seen in particular in Figure 31: - Status bar at the top of the screen: indicates the status of the Bluetooth connection or [iMix s there is no Bluetooth connection; - Tab bar at the bottom of the screen: to select the active page: main page, Settings, Bluetooth, Products and Favorites; - Continuous button 304 to select the product distribution mode continuously; - Purge button 305 to select purge mode; - Dose 306 button to select the dose distribution mode with the dose volume associated with the Dose button; - Blue ball 300 that the user can move in the volume triangle by dragging or with a double tap; - Buttons "-" 302 for each product A, B and C: decreases the selected product fraction by moving along the line connecting the point to the vertex of the selected product; - "+" buttons 302 for each product A, B and C: increases the selected product fraction by moving along the line connecting the point to the vertex of the selected product; - Percent volume fraction of each product: modifiable by the user and updated in real time according to the instruction of the buttons 302 + and - and the position of the ball 300.
[0109] When changing the volume fractions by moving the bale or the + and - buttons, the volume fraction values of products A, B and C are automatically updated. When the volume fractions are changed with the + and - buttons, the ball 300 is automatically moved to the corresponding position on the triangle.
[0110] When starting the application executed on the tablet, it automatically connects to the distributor 11 if it is detected. When the dispenser turns off or the Bluetooth connection is cut off, the tablet disconnects. When the user acts on the sliders for adjusting the proportions of the products A and B, the values are transmitted in real time to the distributor 11.
[0111] The Application Setup page contains the following: - Status bar at the top of the screen: Indicates the status of the Bluetooth connection or [tMix if there is no Bluetooth connection; - Tab bar at the bottom of the screen: to select the active page: main page, Settings, Bluetooth or Info; - Part "Volumes" with a field of text to fill by the user to define the volume of the dose, in ml (2 ml for example) and a field for the volume of the purge, in ml (3 ml for example) . The minimum doses in this example are 0.023 ml and the maximum doses 9.90 ml (3 x 3.3 ml); - Part "Flow" with flow selection: fast ("0.03 ml / s), medium (" 0.02 ml / s) or slow ("0.01 ml / s); - Part "Dose" with the choice of the iterative mixture, to dispense a mixture of products with small volumes delivered one after the other in several steps; Otherwise, the total volume of each product is distributed in one go; - Part "Image Triangle" to choose the image of the triangle that will be displayed on the main page in order to be able to display a triangle with the colors delivered by the distributor 11. By using a button "Choice image" of the page "Settings" one access to an album. The "Products" page of the application includes the following elements in the example considered: - Choice of the value of each product in units of encoder steps, from 0 to 1414.
[0112] Each unit corresponds to a delivered product volume of 2.33 μl, which is the smallest quantity that the dispenser in this example can deliver; when this sheet is displayed, it is the product values of this sheet that are transmitted in real time to the distributor. As soon as the sheet is no longer displayed, the values sent to the distributor are those of the main sheet with the triangle; - Display of motor torque A, B and C in real time with refresh every 45 values. The delivery mode of products is the direct or iterative dose mode, depending on the option chosen in the Adjustment sheet. The "Favorites" page allows you to save configurations as a file. It gives access in the example to 10 files, namely "Configuration 1" to "Configuration10" in addition to the default file. These files record, for example, the following parameters - fractions of products A, B and C - volume of Purge - volume of Dose, - fast, medium or slow flow, - Dose, Purge or Continuous mode, - continuous or iterative distribution. Several tests were carried out with the distribution system according to the example given above. Test 1 The system was tested with ten women with the output interface 110 having cup 115. The system was set to continuous mode. All women have managed to wear makeup with the system, obtaining for the vast majority a makeup they consider more aesthetic than usual. In particular, they can find a better shade and play with the possibilities of the dispenser to optimize the color in several places of their face. They have easily been able to: 1) Look for shades that match their faces and this by iteration of tests. 2) Store one or more colors, 3) Use the dispensing system to deliver the color (s). Test 2 The system was tested with two people (male and female) to mask a particular area (spots in the neck for the man and a spot on the forehead for the woman). The system has been set to dose mode.
[0113] The same procedure as for test 1 was used. Test 3 The dispensing system was used with an airbrush, as illustrated in FIG. 24, using the exit interface 110 provided for this purpose. We could make up the entire face.
[0114] In one case we made makeup with a single color. In a second case, makeup was done by making keys with one color and then finishing with another color, thus changing the color setting between two. In a third case, makeup was done by varying the color during the spray, creating a gradient.
[0115] Test 4 To evaluate the feasibility of remote assistance, the following two experiments are carried out: Firstly, a consumer looks for its hue itself by iterating, as described above with regard to the process of mapping and mapping. 'learning. Thus, she chooses a color, controls the dispenser to deliver a corresponding mixture, makeup with, evaluates the result, and eventually corrects the hue, until finding the appropriate color. Then it is a makeup artist who looks for the hue by proceeding as above, performing all operations, excluding possibly makeup. Finally, we redo the exercise by entrusting the tasks of choice color / assessment hue / correction to a makeup artist operating remotely. The makeup artist is able to choose a suitable shade, but doing the exercise remotely assumes that the makeup artist is able to evaluate the adequacy of the hue via a digital image capture / transmission / playback system. In one embodiment, the consumer and makeup artist both have a tablet, for example an iPad, which are configured to establish a remote communication. The consumer owns the dispenser according to the invention and the make-up artist the application that makes it possible to select the color and to remotely control it, for example via the Bluetooth connection of the consumer's tablet. The latter is installed in a bright place and puts his tablet on a suitable support so that you can film with the integrated camera screen without holding it. Advantageously, the support has additional lighting means, for example ramps of LEDs disposed all around its periphery or on two or three of its sides. The consumer and the makeup artist establish the video communication so that he can see her putting on makeup. The consumer turns on and connects the dispenser to her tablet. The consumer informs the makeup artist of the cartridges inserted in the dispenser. Alternatively, the information is automatically transmitted to the application 30 running on the makeup artist's tablet. After observing the carnation of the consumer, the makeup artist selects a first shade and remotely triggers the delivery of a test dose. The consumer wears makeup on an area recommended by the makeup artist. After application, the makeup artist evaluates the adequacy of the hue. If the hue seems appropriate, he can order the delivery of a larger dose to make up the face. If the hue does not seem appropriate to him, then he chooses another hue and starts again the operation until obtaining the good result.
[0116] The successive tests carried out with the three cartridges are recorded in the form of ratio triplets (% a;% b;% c) such that% a +% b +% c = 100%. An example of a test carried out on the same consumer by the three processes is described below. In the case of the research of the color adapted by the consumer herself, the successive tests were as follows: Essail: 22% to + 38% b + 40% c Test2: 17.3% to + 39.8% b + 42.9% c Test3: 22% to + 39.4% b + 38.6% c In the case of looking for the color matched by a makeup artist in the presence of the consumer, the tests were as follows: Essail: 23.6% a + 52.2% b + 24.2% c Test2: 28.4% to + 40.5% b + 31.1% c Test3: 23% to + 38.5% b + 38.5% c In the case of looking for the hue by a makeup artist remotely via a video link, the essias were the following: Essail: 17.4% a + 41.0% b + 41.6% c Test2: 23% to + 45.5% b + 31.5% c Test3: 19% to + 40.1% b + 40.9% c Color paths to reach the right shade are not the same but the final results are quite close and in all cases satisfactory for the consumer. The consumer can also help validate the adequacy of the hue, so that the role of the advisor is mainly through his expertise to choose in which direction to change the hue.
[0117] In a variant, the consumer makes up her face virtually with the aid of appropriate software, for example that known under the reference Makeup genius. In this case, the counselor sees the makeup result that she wishes and then helps to obtain it by proceeding as described above. Conversely, the hue found by the remote assistance method can be recorded and used as data for virtually makeup the consumer with a simulator, such as the Makeup genius software. Test 5 The dispensing system was used to make custom compacts. A multi-compartment support was filled as illustrated in FIG. 47 with a plurality of different color mixtures successively delivered by the distributor 11.
[0118] The invention is not limited to the examples described. One can for example change the way the pistons are moved in the cartridges. The expression "comprising one" must be understood as being synonymous with "comprising at least one".
