Title: Mixing system for producing a cosmetic product and cosmetic capsule

Description:
TECHNICAL FIELD 
     The disclosure relates to a mixing system for producing a cosmetic product. The disclosure also relates to a capsule containing a cosmetic compound and intended to be used with the mixing system. 
     BACKGROUND 
     In a manner known in itself, cosmetic products, for example hydrating and/or antiwrinkle creams, are in particular made from an oily material forming the oil phase and in particular containing plant oils, butters, emulsifying waxes for cosmetic use, an aqueous phase generally containing pure or floral water, or any agent soluble in water and at least one additive, called active ingredient, giving the cosmetic product the desired efficacy. As an example, this active ingredient may be an antiaging active ingredient such as hyaluronic acid. Furthermore, the cosmetic product may comprise a natural or synthetic perfume, which makes the application and use of the cosmetic product more pleasant. 
     However, the available cosmetic products in emulsion form do not offer the possibility of freely choosing their composition in terms of oil, active ingredients and perfumes, the oil phase in particular influencing the texture of the cream, its viscosity, its spreading power, its sensation upon application. Furthermore, the consumer cannot always find the desired combination of oil-active ingredient-perfume.

     DETAILED DESCRIPTION 
     In reference to the figures and according to the disclosure, a mixing system for producing a cosmetic product will now be described. 
     The mixing system comprises a liquid reservoir  1 . This liquid reservoir  1  comprises an inner wall separating the reservoir  1  into a first liquid compartment and a second liquid compartment, the respective functions of which will be specified below. The first liquid compartment comprises the aqueous phase entering the composition of the cosmetic product, and which is preferably demineralized water or floral water (i.e., a hydrolat), but it may also be a more complex aqueous liquid made up of water and additives such as glycerin or a polymer allowing the creation of a three-dimensional network. The second liquid compartment in turn comprises pure or demineralized water, or simply tap water. In the remainder of the description, the first and second liquid compartments will be called first and second water compartments. 
     The mixing system comprises a liquid pump  2  controlled by a control means of the mixing system and the inlet of which is connected to the outlet of the first water compartment of the reservoir  1 . The control means is for example an electronic circuit supplied with electricity by means of a transformer comprised in the mixing system and connected to the home electrical system. For greater simplicity in the remainder of the description, this liquid pump  2  will be called water pump  2 . The water pump  2  is suitable for guaranteeing the circulation of water from the first water compartment of the reservoir  1  toward a liquid intake pipe  3 , which will be called water intake pipe  3  in the remainder of the description for greater simplicity. This intake pipe  3  guarantees the flow of liquid used to produce the cosmetic product in a mixing device of the mixing system, as will be explained later. 
     The mixing system further comprises a cylindrical moving plate  4 , resting on a first support  26  secured to the casing of the mixing system and able to be controlled in rotation about a vertical axis  14   a  connected to a motor  14  secured to the casing of the mixing system, for example an electric motor. This moving plate  4  comprises at least two compartments  5 ,  6 , preferably three compartments  5 ,  6 ,  10 , formed in the body of the moving plate  4 . Furthermore, the bottom wall of each compartment  5 ,  6 ,  10  comprises, in its center, a circular through orifice  5   a ,  6   a ,  10   a , the function of which will be explained later. 
     The compartments  5 ,  6 ,  10  of the moving plate  4  are intended to house capsules  7 ,  8  containing various compounds for developing the final cosmetic product. The first compartment  5  of the moving plate is suitable for housing a capsule  7  containing a cosmetic texturizing agent. This texturizing agent is preferably a cosmetic oil, optionally doped with an emulsifier with a base of amphiphilic molecules. Alternatively, this texturizing agent is a polymer for cosmetic use, for example a polyoside such as xanthan gum or an acrylic acid polymer of the carbomer type. For greater simplicity in the remainder of the description, this cosmetic texturizing agent capsule  7  will be called cosmetic oil capsule  7 . 
     The second compartment  6  of the moving plate is suitable for housing a capsule  8  containing a cosmetic active ingredient, i.e., a compound known for its cosmetic properties, for example antiwrinkle or hydrating properties. Furthermore, this capsule  8  may comprise a preservative product mixed with the cosmetic active ingredient. The third compartment  10  of the moving plate is in turn suitable for housing a capsule containing a cosmetic perfume, to scent the final cosmetic product. 
     Each capsule  7 ,  8  comprises a cylindrical wall  30 , a bottom wall  31  with a central orifice  33  and a piston-forming wall  32  housed in the cylindrical wall  30 . Thus, the cosmetic compound contained in the capsule  7 ,  8 , whether it involves the cosmetic oil, the cosmetic active ingredient or the cosmetic perfume, is found in the cylindrical wall  30  between the bottom wall  31  and the piston-forming wall  32 . Preferably, in order to avoid any contamination of the compound contained in the capsule, the central orifice  33  is sealed by a frangible membrane seal  35 . 
     Furthermore, the moving plate  4  comprises a funnel-shaped compartment  13  able to be brought above the mixing device, to place the outlet of the water intake pipe  3  in fluid communication with the mixing device. Alternatively (not shown), the outlet of the water intake pipe  3  is positioned directly in fluid communication with the mixing device. 
     The mixing system further comprises means for pressurized expulsion  9  of the content of each capsule  7 ,  8  outside its corresponding compartment  5 ,  6 ,  10  in which it is housed. The expulsion means  9  comprise a motor  9   a , preferably electric, secured to a second support  27 , in turn secured to the casing of the mixing system and positioned opposite the moving plate  4  at a distance from the latter, such that the moving plate  4  is arranged between the first and second supports  26 ,  27 . The expulsion means  9  also comprise a rod  9   b  that is translatable via this motor  9   a . This rod  9   b  is thus able to exert pressure on the piston-forming wall  32  of each capsule  7 ,  8  housed in its corresponding compartment  5 ,  6 ,  10  of the moving plate  4 , which causes the piercing of the frangible membrane seal  35  closing the central orifice  33  of the capsule  7 ,  8  and the forced flow outside the capsule of its content. The products contained in the capsules  7 ,  8  will successively flow through the respective through orifices  5   a ,  6   a ,  10   a  of the compartments  5 ,  6 ,  10  of the open plate  4 , as will be seen later in the description. 
     Preferably, in order to optimize the expulsion of the content of the capsule  7 ,  8 , the bottom wall  31  of the capsule and the surface of the piston-forming wall  32  situated opposite the bottom wall  31  have substantially frustoconical complementary shapes. Furthermore, the bottom wall  31  of the capsule may comprise a tubular ring  34  with a circular section protruding coaxially to the orifice  33  of the bottom wall  31  of the capsule. Thus, when the capsule  7 ,  8  is housed in its compartment  5 ,  6 ,  10  of the moving plate  4 , the tubular ring  34  is housed in the circular through orifice  5   a ,  6   a ,  10   a  of the corresponding compartment  5 ,  6 ,  10 . In this way, the content expelled from the corresponding capsule does not come into contact with the cylindrical surface delimiting the through orifice  5   a ,  6   a ,  10   a  of the corresponding compartment  5 ,  6 ,  10 . In the presence of the tubular ring  34 , the frangible membrane seal is glued on the free end of the ring  34  so as to seal the central orifice  33 . 
     The mixing device includes a container  11  positioned below the moving plate  4  controlled to successively position, above the container  11 , the outlet  5   a ,  6   a ,  10   a  of each of the compartments  5 ,  6 ,  10  and the outlet  13   a  of the funnel-shaped compartment  13  of the moving plate  4 , so that the container  11  can successively receive the water, the cosmetic oil, the active ingredient and, if applicable, the cosmetic perfume expelled from their respective compartments  13 ,  5 ,  6 ,  10 . The mixing device also comprises a mixing member  12  housed in the container  11  and able to create the cosmetic product in this container  11  from a mixture of water, cosmetic oil and cosmetic active ingredient, and if applicable cosmetic perfume. 
     According to one preferred embodiment shown in the figures, the container  11  of the mixing device is a removable cylindrical tube closed by a bottom wall to allow the storage of the produced cosmetic product. The mixing member  12  in this embodiment comprises a piston  12   a  forming the bottom wall of the container  11  and a plurality of radial fins  22   a  secured to the piston  12   a  and protruding from the upper face of the piston  12   a . The piston  12   a  is able to be rotated with the fins  22   a , when the removable container  11  is mounted on the mixing system, by a toothed crown  23  mounted in a support base  25  of the container  11  coaxially to the latter. The axial teeth  24   a  of the crown  23  are all situated on a same side of the crown  23  and are able to be coupled to the piston  12   a . Furthermore, the toothed crown  23  comprises an axle portion  24   b  protruding perpendicularly to the crown  23  and also intended to be coupled by clipping to the piston  12   a  in order to facilitate the centering of the piston  12   a  on the toothed crown  23  and to prevent any translational movement of the piston  12   a  in the container  11  when the piston  12   a  is rotated. The crown  23  can in turn be rotated by an electric motor secured to the base  25  and controlled by the control means of the mixing system. Furthermore, the support base  25  is translatable to make it possible to bring the opening of the container  11  further from or closer to the moving plate  4 . 
     Alternatively, the mixing member  12  forming the bottom wall of the container is made in two parts. The first part is the piston  12   b  in itself, which is the bottom wall of the container  11 , the piston  12   b  in this alternative being immobile in rotation. The second part comprises a rod  39  axially passing through the piston  12   b  at its center, the opposite ends of this rod  39  respectively comprising a mixing disc  28  comprising fins  22   b  circumferentially secured to this mixing disc  28 , and the disc  29  for driving the rotation of the rod  39 , the discs  28 ,  29  being arranged on either side of the body of the piston  12   b . The rotational driving disc  29  is able to be rotated with the rod  39  and the mixing disc  28  with fins  22   b , when the removable container  11  is mounted on the mixing system, by a toothed crown  37  mounted in the support base  25  of the container  11  coaxially to the latter. The teeth  37   a  of the crown  37  extend radially on a face of the latter and are able to be coupled by clipping to the rotational driving disc  29 , in oblong orifices  29   a  provided to that end. The crown  37  can in turn be rotated by an electric motor of the mixing system controlled by the control means of the mixing system. The length of the rod  39  is greater than the thickness of the piston  12   b . Thus, when the driving disc  29  is clipped on the crown  37 , the mixing disc  28  is moved away from the upper surface of the piston  12   b  in order on the one hand to prevent any rubbing of this mixing disc  28  on the upper surface of the piston  12   b , and on the other hand to improve the effectiveness of the mixing in the container  11 , the mixture being suctioned through the mixing disc  28 . Conversely, when the user removes the container  11  from the base  25  of the mixing system, the teeth  37   a  of the wheel  37  first retain the rotational driving disc  29 , which causes the movement of the rod  39  relative to the piston  12   b , such that the disc  28  with fins  22   b  comes into contact with the corresponding surface of the piston  12   b  just before the unclipping of the rotational driving disc  29 . Preferably, the mixing disc  28  with fins  22   b  can be housed in a housing made in the wall of the piston  12   b  at the upper surface thereof. 
     Furthermore, irrespective of the alternative embodiment of the piston, the bottom of the container  11  includes notches  11   a  for embedding in corresponding stops on the base  25 , which prevents the container  11  from rotating during the rotation of the piston  12   a  or the mixing disc  28 , so that only the latter or the piston  12   a  rotate. Lastly, the shape and the position of the fins  22   a  of the piston  12   a  or alternatively of the fins  22   b  of the mixing disc  28  make it possible, preferably, to produce an emulsion from the oil phase coming from the oil capsule  7  and the water coming from the corresponding water compartment. In the remainder of the description, reference will preferably made to an emulsion, but any other type of cosmetic product that is easier to produce, for example a gel or a lotion, can be made with the mixing system. 
     The cosmetic oil contained in the corresponding capsule  7  is in the solid state. It is therefore necessary, in order to produce the mixture of water and cosmetic oil, to melt this oil and bring it to a temperature of around 75° C. A heating resistance  19  is incorporated into the compartment  5  of the moving plate  4  of the cosmetic oil capsule  7 . This heating resistance  19  is in the form of a tubular ring and is provided to surround the cylindrical wall of the cosmetic oil capsule. Preferably, this electrical resistance  19  comprises a resilient material such that the resistance  19  exerts pressure on the cylindrical wall  30  of the capsule  7  when the latter is housed in its corresponding compartment  5 . Furthermore, as shown in particular in  FIG.  1   , a heating means  20  for the water controlled by the control means of the mixing system is incorporated into the mixing system and connected to the water pump  2  of the mixing system and the water intake pipe  3 . This heating means  20  is preferably an internal electrical resistance heating block. 
     It is preferable first to produce, in the container  11 , an emulsion of hot water and cosmetic oil, then to cool this emulsion. To that end, the mixing system comprises a hollow cooling water circulation block  17  partially surrounding the container  11 . The water inlet and outlet of this block  17  are connected to the second water compartment of the reservoir  1  by another pump  18  to guarantee the cooling of the emulsion in the container  11 . The quantity of emulsion to be cooled being negligible compared to the quantity of water in the compartment  28 , the circulation of the cooling water in a closed loop is sufficient without risking this water heating up too much. At the end of this cooling, the active ingredient and the cosmetic perfume are added into the emulsion to form the cosmetic product, by successive forced expulsion of the content of these capsules through orifices of the corresponding compartments of the moving plate in the container. 
     The mixing system comprises a solenoid valve  15  controlled by the control means and arranged between the water pump  2  and the internal electrical resistance heating block  20  in order to control the circulation of water in the container  11 . To make the connections possible, the inlet and the outlet of the solenoid valve are respectively connected to the outlet of the water pump  2  of the mixing system and to the inlet of the heating block  20  by means of flexible or rigid lines  16 . It is also possible to place the solenoid valve elsewhere in the system, in particular between the heating block  20  and the inlet of the water intake pipe. Furthermore, all of the connections are done by means of such flexible or rigid lines  16 , for example made from polyvinyl chloride. 
     The mixing system also comprises a flowmeter  21  connected to the outlet of the water pump  2  of the mixing system. As will be seen hereinafter, the data from the flowmeter  21  are used by the control means to deliver the necessary and sufficient volume of water through the water intake pipe  3  to produce the cosmetic product. 
     A method for manufacturing a cosmetic product using a mixing system according to the disclosure will now be described. 
     First, the user places the base  25  in the low position, if it is not already there, and clips the mixing member  12  on the teeth of the toothed crown  23 ,  37 ; next he clips the container  11  above the piston  12   a ,  12   b , the piston  12   a ,  12   b  then being inside the container  11 . He can then mount the base  25  in the high position, the top of the bottle then being just below the moving plate  4 . It is also possible to clip the container  11  while the base  25  is in the high position, if the height of the container  11  allows it. The user then powers on the mixing system and initiates, for example by pressing a button provided to that end, a program for producing cosmetic products stored in a memory space of the control means of the mixing system, this program being executed by the control means to allow the implementation of the method for producing the cosmetic product. 
     During the first step of the method, the control means steers the rotation of the moving plate  4  so that the compartment  5  of the moving plate  4 , intended to receive the cosmetic oil capsule  7 , is accessible to the user so that the latter can house a cosmetic oil capsule  7  therein. Indeed, the second support  27  includes a notched opening  38  in the wall of the second support  27  from the edge of this wall and allowing the successive access to each compartment  5 ,  6 ,  10  of the moving plate  4 . After a determined time, or alternatively when detection means  40  of the mixing system secured to the second support  27  detect the presence of the cosmetic oil capsule  7 , the control means steers the rotation of the moving plate  4  so that the compartment  6  of the moving plate  4 , intended to receive the cosmetic active ingredient capsule  8 , is opposite the opening  38  of the second support  27  in order to be accessible to the user so that the latter can house a cosmetic active ingredient capsule  8  therein. If applicable, after detection of this capsule  8  or after a determined length of time has elapsed, the control means steer the rotation of the moving plate  4  so that the compartment  10  of the moving plate  4 , intended to receive the cosmetic perfume capsule, is accessible to the user so that the latter can house a cosmetic perfume capsule therein. Alternatively, it is the user who can control the rotation of the moving plate  4 , for example by pressing on a button of the mixing system provided to that end, in order successively to introduce the capsules  7 ,  8  into their corresponding compartment  5 ,  6 ,  10 . 
     Preferably, the cosmetic capsules  7 ,  8  comprise a circular frangible membrane  36  sealing the opening of the cylindrical wall  30  of the capsule situated opposite the orifice  33  of the bottom wall  31  of the capsule  7 ,  8 . Each frangible membrane  36  can comprise a bar code or any other identification means able to be read by the detection means  40  of the mixing system, in order in particular to determine the type of oil, the type of active ingredient or the type of cosmetic perfume. In order to facilitate the adhesion of this frangible membrane  36 , the cylindrical wall  30  of the capsule  7 ,  8  may comprise, at its opening opposite the orifice  33  of the bottom wall  31 , a flange on which the membrane  36  is adhered. 
     After reading the barcode printed on the frangible membrane  36  of the cosmetic oil capsule  7  and during the second step of the method, the mixing system commands the supply of energy of the heating means  19  arranged in the compartment  5  in which the cosmetic oil capsule  7  is housed, so as to melt the cosmetic oil. In parallel, the control means steers the supply of power to the electrical resistance of the heating block  20  in order to subsequently heat the water that will be brought into the block  20  to a temperature of about 90° C. The barcode of the capsule  7 ,  8  also allows the mixing system to calculate the necessary volume of water that will be included in the production of the final product in the container  11 . 
     Alternatively, if the detection means detects that the capsule  7  comprises a texturizing agent that does not require heating, then neither the water nor the capsule  7  are heated, since the control means will not supply energy to the electrical resistance of the heating block  20  and the heating means  19  of the capsule  7 . Thus, the second step of the method is avoided. 
     The control means steers, during the third step of the method, the rotation of the moving plate  4  such that the outlet  13   a  of the funnel-shaped compartment  13  is respectively opposite the container  11  and the outlet of the water intake pipe  3 . The control means next steers the opening of the solenoid valve  15  and starts up the water pump  2  such that a determined volume of hot water calculated from data from the flowmeter  21  passes through the heating block  20  to be heated to 90° C. Once the temperature of the water in the heating block reaches 90° C., the water flows into the container  11 , via the water intake pipe  3 . Once this volume of hot water has flowed into the container  11 , the control means steers the closing of the solenoid valve  15  and the water pump  2 , and stops the supply of energy to the resistance of the water heating block  20 . 
     In the alternative where the capsules  7 ,  8  do not comprise barcodes, it is the user who chooses, via an interface means comprised in the mixing system, on the one hand whether the heating of the texturizing agent capsule  7  and water is necessary, and on the other hand the volume of water needed to produce the cosmetic product. For example, the mixing system may comprise a means for selecting a so-called “hot” production method, a means for selecting a so-called “cold” production method, and a cursor making it possible to adjust the necessary volume of water. 
     During the fourth step of the method, the control means steers the rotation of the moving plate  4  such that the outlet  5   a  of the compartment  5  in which the oil capsule  7  is housed is opposite the container  11 , and the piston-forming wall  32  of the capsule  7 , or more specifically the frangible membrane  36  covering the opening of the cylindrical wall  30  of the capsule  7 , is opposite the moving rod  9   b  of the pressurized expulsion means  9 . Then, the motor  9   a  of the pressurized expulsion means  9  is turned on by the control means in order to move the moving rod  9   b  vertically toward the piston-forming wall  32  of the capsule  7 . The moving rod  9   b  then tears the frangible membrane  36 , then bears against the piston  32 , exerting pressure on the latter to cause the piercing of the frangible membrane seal  35  in the bottom wall  31  and the forced flow of the cosmetic oil from the capsule  7  into the container  11 . Once the piston-forming wall  32  touches the bottom wall  31  of the capsule  7 , the control means steers the rising of the moving rod  9   b  via the corresponding motor  9   a . Concomitantly, or preferably just after the expulsion of the cosmetic oil from the corresponding capsule  7 , the control means powers on the motor connected to the toothed wheel  23 ,  37  in order to rotate the latter and consequently to rotate the piston  12   a  and/or the fins  22   a ,  22   b  of the mixing device  12  in order to produce the emulsion from the melted cosmetic oil and hot water contained in the container  11 . 
     After a given time, the water pump  18  connected to the second water compartment of the reservoir  1  and the cooling water circulation block  17  is turned on for a given time to cool the emulsion in the container  11  during the fifth step of the method. 
     Once the cooling time has elapsed and the emulsion has reached a temperature of about 40° C., the sixth step of the method is carried out: the control means optionally stops the water pump  18  connected to the cooling water circulation block  17  and commands the rotation of the moving plate  4  such that the outlet  6   a  of the compartment  6  in which the active ingredient capsule  8  is housed is opposite the container  11 , and the piston-forming wall  32  of the capsule  8 , or more specifically the frangible membrane  36  covering the opening of the cylindrical wall  30  of the capsule  8 , is opposite the moving rod  9   b  of the pressurized expulsion means  9 . Then, the motor  9   a  of the pressurized expulsion means  9  is turned on by the control means in order to move the moving rod  9   b  vertically toward the piston-forming wall  32  of the capsule  8 . The moving rod  9   b  then tears the frangible membrane  36 , then bears against the piston  32 , exerting pressure on the latter to cause the piercing of the frangible membrane  35  of the bottom wall  31  and the forced flow of the cosmetic active ingredient from the capsule  8  into the container  11 . Once the piston-forming wall  32  touches the bottom wall  31  of the capsule  8 , the control means steers the rising of the moving rod  9   b  via the corresponding motor  9   a . The electric motor then rotates the piston  12   a  and the fins  22   a  or alternatively the mixing disc  28  and the fins  23   b  of the mixing member  12  remains supplied with power, allowing the incorporation of the cosmetic active ingredient into the emulsion. 
     Optionally, if the user initially chose an advanced program of the mixing system, the rotation of the moving plate is steered by the corresponding motor so as to make the compartment  6  intended to house an active ingredient capsule  8  accessible to the user. The latter can then remove the used active ingredient capsule  8  and install a new one. The sixth step is then repeated, such that the final cosmetic product comprises two cosmetic active ingredients with different and/or complementary virtues. Alternatively, the sixth step is repeated after the seventh step that will be described hereinafter, i.e., after introducing cosmetic perfume into the container  11 . 
     During the seventh step of the method, the control means steers the rotation of the moving plate  4  such that the outlet of the compartment  11  in which the perfume capsule is housed is opposite the container  11 , and the piston-forming wall  32  of the capsule, or more specifically the frangible membrane  36  covering the opening of the cylindrical wall  30  of the capsule, is opposite the moving rod  9   b  of the pressurized expulsion means  9 . Then, the motor of the pressurized expulsion means  9  is turned on by the control means in order to move the moving rod  9   b  vertically toward the piston-forming wall  32  of the capsule. The moving rod  9   b  then tears the frangible membrane  36 , then bears against the piston  32 , exerting pressure on the latter to cause the piercing of the frangible membrane  35  of the bottom wall  31  and the forced flow of the cosmetic perfume from the capsule into the container  11 . Once the piston-forming wall  32  touches the bottom wall  31  of the capsule, the control means controls the rising of the moving rod  9   b  via the corresponding motor  9   a . The electric motor that rotates the piston  12   a  and the fins  22   a  or alternatively the mixing disc  28  and the fins  23   b  of the mixing member  12  remains supplied with power, allowing the incorporation of the cosmetic perfume into the emulsion. 
     Alternatively, if no perfume capsule is detected in the corresponding compartment  10 , the seventh step of the method does not take place. 
     During the eighth step of the method, the control means powers off the motor intended to drive the toothed crown  23 ,  37 , which stops the piston  12   a  and/or the fins  22   a ,  22   b  of the mixing member  12 , when the cosmetic product reaches a temperature below 35° C., or even 30° C., or after a determined length of time. The user can then recover the container  11  with the piston  12   a ,  12   b  that serves as bottom wall. A lid can then be placed on the opening of the container  11  to shelter the cosmetic product from air and preserve it. More specifically, the user lowers the base  25 , clips the lid on the container  11  and unclips the container  11  from the toothed crown  23 ,  37 . 
     Advantageously, the user can use the container  11  removed from the mixing system and filled with the cosmetic product made using the mixing system as bottle for storing and dispensing the cosmetic product. To that end, a head closes the opening of the container  11  opposite the piston  12   a ,  12   b , said head including a pump for dispensing the cosmetic product provided with a trigger able to be actuated manually. Furthermore, the head comprises a rigid tube plunged into the cosmetic product. This head with dispensing pump and trigger is well known by one skilled in the art, and is for example found on certain bottles of cosmetic creams. Thus, when the user presses on the trigger, a volume of cosmetic product is dispensed at the outlet of the head. When the user releases the trigger, a vacuum is created in the container  11 , which causes the piston  12   a ,  12   b  to move in the container  11  toward the head, to offset the dispensed volume of cosmetic product. The free end of the rigid tube secured to the head will therefore always be submerged in the cosmetic product. 
     The configuration of the mixing system of the disclosure is not limited to the embodiment previously described and shown in the figures. It has been provided solely as a non-limiting example. Multiple changes can be made without going beyond the scope of the disclosure. In particular, the container  11  of the mixing device may not be removable and the mixing member  12  then comprises a helix mounted at the bottom of the container  11  on an axle coaxial to the latter. This axle is mounted in the bottom wall of the container  11  and can be driven by an electric motor mounted in the mixing system and controlled by the control means of the mixing system. Furthermore, in order to recover the cosmetic product produced in a storage bottle, the container  11  comprises a timed valve in its bottom wall to allow the flow of the emulsion by gravity. Alternatively, this valve can be actuated manually, and the cosmetic product flows by gravity if the bottle of the latter is relatively fluid, or by overpressure applied in the container  11  by an appropriate hydraulic or pneumatic system if the product is too thick or viscous. Lastly, it is possible to conceive a cooling block  17  without water circulation, this block  17 , comprising a cold accumulator liquid, being placed in the freezer before use of the mixer system. In this case, the liquid reservoir  1  has a single compartment and the second water pump  18  is not necessary. Lastly, it is possible to conceive of replacing the heating block  20  for the water with a heating means of the electrical resistance type housed in the funnel-shaped compartment  13 , so as to heat the water flowing in the funnel-shaped compartment  13  directly in the latter.
