Description

[Technical field]

[0001] The present invention relates to a manufacturing device for producing a formulation, in particular a cosmetic formulation, or more particularly for the production of a formulation by mixing two compositions. [Background technology]

[0002] The patent document FR 3026622 discloses a manufacturing device for producing formulations, more particularly cosmetic products, which comprises: a first capsule comprising a first compartment containing a quantity of a first composition and a first connecting part; a second capsule comprising a second compartment containing a quantity of a second composition and a second connecting part configured to be connected to the first connecting part; and a mixer configured to receive the first and second capsules and to mix the first and second compositions directly in the first and second capsules to obtain the cosmetic product.

[0003] The mixer is, in particular, a first pressure element including a first pressure surface configured to apply a pressure to a first deformable section of the first capsule perpendicular to a direction of movement of the first pressure element; a second pressure element including a second pressure surface configured to apply a pressure to a second deformable section of the second capsule perpendicular to the direction of movement of the second pressure element; and a drive motor mechanically coupled to the first and second pressing elements and configured to enable a cyclic movement of the first and second pressing elements between an inactive position and an active position. Such a manufacturing device enables the production of personalized cosmetic products from different capsules by the final consumer. [Prior art documents] [Patent documents]

[0004] [Patent Document 1] French Patent No. 3026622 Summary of the Invention [Problem to be solved by the invention]

[0005] However, the structure of the manufacturing device described in Patent Document 1 (FR 3026622) requires the provision of a drive motor of considerable size in order to transmit to the first and second deformable compartments a pressure adapted to ensure the movement of the contents from the first compartment to the second compartment and vice versa, this being especially the case when the first and second deformable compartments or the connecting channels associated with the first and second deformable compartments are closed by weakened welded areas.

[0006] The projection of a drive motor with significant size substantially increases the manufacturing costs of the manufacturing equipment as well as its volume and weight.

[0007] Furthermore, capsule mixing has proven to be more complicated than expected, requiring improvements in both the materials and the manner in which the materials are used. [Means for solving the problem]

[0008] The present invention aims to overcome all or part of these drawbacks. The technical problem underlying the present invention is therefore to provide an apparatus for producing formulations that is simple, compact and easy to use, while having a simple structure and low cost.

[0009] In particular, some designs in the form of mixers capable of receiving a receiving device intended to consolidate capsules pose additional problems regarding the management of the movement of the different elements. To avoid misuse, it is preferable to leave most of the actions to be achieved to the manufacturing device, in particular to ensure the achievement of a hermetic bond between the capsules.

[0010] In this regard, the invention proposes a mixer adapted to receive a receiving device to form a mixer, the production device comprising: a support defining a receiving housing capable of receiving a receiving device configured to receive a first and a second capsule containing a first composition and a second composition, respectively, said two capsules being fluidly connected to each other; an actuation system movable within the receiving housing for applying pressure to the receiving device and / or the first and / or second capsules; a coupling mechanism movable relative to said support, * in the insertion position, does not interfere with the insertion of the receiving device into or the withdrawal of the receiving device from the receiving housing; and a coupling mechanism configured to exert a force on an actuation surface of the receiving device in a coupling position; Equipped with.

[0012] In one embodiment, the mixer includes an auxiliary, preferably electric, motor configured to move the coupling mechanism between its two positions.

[0013] In one embodiment, at least two of the coupling mechanism, the holding mechanism, and the clamping mechanism are kinematically linked by a gear or a common pulley.

[0014] In one embodiment, the auxiliary motor drives and rotates a gear or a common pulley.

[0015] In one embodiment, the auxiliary motor is configured to be powered only when the coupling mechanism needs to move.

[0016] In one embodiment, the coupling mechanism comprises a coupling wheel rotatably moveable about a coupling wheel axis.

[0017] In one embodiment, the docking wheel has two different diameters, whereby in the insertion position, the docking wheel does not extend into the receiving housing, and in the docking position, the docking wheel extends into the receiving housing to exert a force on the working surface of the receiving device.

[0018] In one embodiment, the coupling mechanism, and therefore the coupling wheels, are distinct from the drive system.

[0019] In one embodiment, the retention mechanism comprises a retention wheel rotatably moveable about a retention wheel axis.

[0020] In one embodiment, the retaining wheel has two different diameters, whereby in the insertion position, the retaining wheel does not extend into the receiving housing, and in the blocking position, the retaining wheel extends into the receiving housing to contact the receiving device.

[0021] In one embodiment, the retaining wheel axis and the coupling wheel axis are coincident.

[0022] In one embodiment, the actuation system comprises: a first actuating member arranged on one side of the receiving housing and movable within the receiving housing for transmitting pressure to a first actuating surface of the receiving device; a second actuating member arranged on another side, preferably the opposite side, of the receiving housing and movable within the receiving housing for transmitting pressure to a second actuating surface of the receiving device.

[0023] In one embodiment, the coupling mechanism is movable and located at a location different from the location of the actuation system to exert a pressure on the receiving device other than that of the actuation system.

[0024] In one embodiment, the clamping mechanism is a clamping wheel rotatably moveable about a clamping wheel axis.

[0025] In one embodiment, the mixer includes a fixed clamping wall against which the clamping wheel clamps at the clamping position.

[0026] In one embodiment, the clamping wheel is rotatably mounted on the arm and is itself rotatably movable about the arm axis.

[0027] In one embodiment, the clamping wheel is movably mounted to the arm with a return means which tends to translate the moveable wheel away from the arm axis.

[0028] In one embodiment, the clamping wheel rolls against the guide wall, preferably via teeth, whereby the clamping wheel rotates in the opposite direction to the arm.

[0029] In one embodiment, the arms are kinematically coupled to a common gear that kinematically couples the coupling mechanism to at least one of the holding mechanism and the clamping mechanism.

[0035] 1A and 1B show a production apparatus 2 according to a first embodiment of the present invention, configured to produce a composition, which may be, for example, a cosmetic product, a hair care product, a pharmaceutical product, a phytosanitary product, a maintenance product, a cleaning product, or an agricultural food product. When the composition produced is a cosmetic product, the cosmetic product may be, for example, a homogenized emulsion, a homogenized solution, or a mixture of several miscible phases.

[0036] The manufacturing device 2 allows the preparation of single sections, mainly for personal use, small scale and ready to use. Its dimensions must therefore meet the constraints of space requirements in bathrooms, beauty salons, luggage (for transport), etc. The manufacturing device 2 therefore has no dimensions greater than 40 cm.

[0037] The manufacturing apparatus 2 includes a receiving means configured to receive first and second capsules 3, 4, also called pods or packaging units, each containing a predetermined amount of a first composition and a predetermined amount of a second composition, to obtain a cosmetic product, and a mixer 6 configured to mix the first and second compositions contained in the first and second capsules 3, 4 received in the manufacturing apparatus 2.

[0038] The mixer 6 comprises a receiving housing forming part of the receiving means, which is arranged to receive the first and second capsules 3 , 4 directly or via a specific receiving device 5 .

[0039] In one preferred embodiment, as can be seen in particular in all Figures 1A, 1B, 7A, 8A, 8B, 8C, the mixer 6 comprises a receiving housing 32 capable of receiving, in a removable manner, the receiving device 5. In this case, the receiving housing 32 has a shape substantially complementary to that of the receiving device 5. The mixer 6 further comprises an actuation system 35 configured to exert, where appropriate, a force on the first and second capsules 3, 4 via the receiving device 5, allowing mixing and kneading of the composition to be produced.

[0040] The receiving device 5, also called shuttle (as it serves as a carrier for the first and second capsules 3, 4), preferably has a relatively symmetrical shape, either rectangular or elliptical / oval. A longitudinal direction X is defined, which corresponds to the direction along which the receiving device 5 is inserted into the receiving housing 32. As a result, the longitudinal direction X and the insertion direction coincide when the receiving device 5 is inserted into the mixer 6.

[0041] Advantageously, the mixer 6 is configured to mix the first and second compositions in the receiving device 5, preferably in the first and second capsules 3, 4, without either composition coming into contact with the manufacturing device 2.

[0042] As indicated above, some embodiments presented herein are applicable to a manufacturing apparatus 2 without a receiving device 5, i.e., with first and second capsules 3, 4 that can be placed directly in the mixer.

[0043] Advantageously, the first composition is the first phase of the cosmetic product to be produced, such as the fatty phase of the cosmetic product, and the second composition is the second phase of the cosmetic product, such as the aqueous phase of the cosmetic product. For example, the fatty phase may constitute the base of the cosmetic product to be produced, and the aqueous phase may contain the active elements and thus constitute the active ingredient complex of the cosmetic product to be produced.

[0044] capsule The two capsules that can be used in the proposed manufacturing device 2 are described in detail in the document filed under French application no. 1755744, the contents of which are fully incorporated herein. The capsules themselves are not the subject of the present invention. The following points will be noted for the remainder of the description. More specifically, as shown in Figures 2A, 2B, 3A, 3B, 4A, 4B, the first and second capsules 3, 4 are separate from each other and are configured to be fluidically connected to each other. Moreover, each of the first and second capsules 3, 4 is advantageously single-use. The first capsule 3 comprises a first deformable section 3.1 with a bulging shape containing a first composition, a first connecting part 3.2, and a first connecting passage 3.3 configured to fluidly connect the first deformable section 3.1 and the first connecting part 3.2. Advantageously, the first connecting passage 3.3 is formed by a first connecting channel. The first connecting portion 3.2 more specifically comprises a female connecting end portion 3.4, e.g. cylindrical, which is fluidly connected to the first connecting passage 3.3. The first capsule 3 comprises a flat surface 3.7 through which the connecting portion 3.2 passes.

[0045] The first capsule 3 further comprises an outlet passage 3.5, such as an outlet channel, fluidly connected to the first connecting passage 3.3 and equipped with an outlet orifice 3.6. Advantageously, the outlet passage 3.5 extends in the extension of the first connecting passage 3.3 and is substantially parallel to the first connecting passage 3.3. In this case, the outlet passage 3.5 may be attached to the first capsule 3 or to the second capsule 4 as well. In fact, the outlet passage 3.5 is only operatively loaded when the manufacturing device 2 is used.

[0046] The second capsule 4 comprises a second deformable section 4.1 in an expanded shape containing a second composition, a second connecting part 4.2 configured to be connected to the first connecting part 3.2, and a second connecting passage 4.3 configured to fluidically connect the second deformable section 4.1 and the second connecting part 4.2. Advantageously, the second connecting passage 4.3 is formed by a second connecting channel, the second connecting part 4.2 extending substantially perpendicularly to the second connecting passage 4.3. The second connecting part 4.2 more specifically comprises a male connecting end part 4.4, for example cylindrical, fluidically connected to the second connecting passage 4.3 and configured to receive the female connecting end part 3.4 in a sealed manner. The second capsule 4 comprises a plane 4.7 through which the second connecting part 4.2 passes.

[0047] The first and second capsules 3, 4, and more particularly the first and second deformable compartments 3.1, 4.1, respectively, are closed by interlocking welds that ensure the sealing of the first and second capsules 3, 4, and that are breakable as soon as threshold pressures are reached, which may be reached in the mixer 6, and which are explained in detail in the description of the document filed under French application no. 1755744.

[0048] Each of the first and second capsules 3, 4 is adapted to contain the total mixture or substantially the total mixture formed by a given amount of the first composition and a given amount of the second composition. In this respect, the deformable compartment is flexible or a buffer area is provided. The written description filed under French application no. 1755744 also explains it in detail.

[0049] Receptor More specifically, as shown in Figures 2A, 2B, 3A, 3B, 4A, 4B and 5, the receiving device 5 can occupy an open position in which the first and second capsules 3, 4 can be introduced into the receiving device, and a closed position in which the receiving device 5 can hold the first and second capsules 3, 4 in place.

[0050] The receiving device 5 more specifically takes the form of a receiving case 7 (FIGS. 2A, 2B) configured to at least partially receive and house the first and second capsules 3, 4. The receiving device 5 comprises a first protective shell 8 and a second protective shell 9, which are articulated relative to each other around an articulation axis 10 (or hinge) and between a first position (see FIGS. 2A, 2B, 5) corresponding to an open position of the receiving device 5 and a second position (see FIGS. 4A, 4B) corresponding to a closed position of the receiving device 5. The receiving device 5 further comprises a first support part 11 and a second support part 12, both arranged in the receiving case 7. The first and second support parts 11, 12 each comprise a first receiving area 13 configured to receive the first capsule 3 and a second receiving area 14 configured to receive the second capsule 4. The first and second protective shells 8, 9 respectively include openings 8.2, 9.2 for allowing access to the first or second receiving sites 13, 14. These openings 8.2, 9.2 define an insertion face of the receiving device 5. Opposite the insertion face, the receiving device 5 includes a withdrawal face.

[0051] Advantageously, the first support part 11 comprises a receiving wedge 15 configured to receive a peripheral portion of the first capsule 3, and the second support part 12, for that matter, comprises a receiving wedge 15 configured to receive a peripheral portion of the second capsule 4. These receiving wedges 15 in part define the first and second receiving sites 13, 14.

[0052] The first support part 11 comprises a first locating surface 11.1 configured to guide and receive (in contact) the planar surface 3.7 of the first capsule 3. The first locating surface 11.1 thus defines, in part, a first receiving site 13. Similarly, the second support part 12 comprises a second locating surface 12.1 configured to guide and receive (in contact) the planar surface 4.7 of the second capsule. The locating surface 12.1 thus defines, in part, a second receiving site 14. When the first and second capsules 3, 4 are inserted, their respective planar surfaces 3.7, 4.7 face each other with the two locating surfaces 11.1, 12.1 between them.

[0053] To allow the passage of the first and second connecting parts 3.2, 4.2 of the first and second capsules 3, 4, the first and second arrangement faces 11.1, 12.1 respectively comprise passage openings 11.2, 12.2 in the form of slots which open outwardly along the insertion axis X (FIG. 2A).

[0054] The receiving device 5 further comprises a partition wall 22 that defines a dividing surface (FIGS. 3A, 3B). The partition wall 22 is arranged between the first and second receiving sites 13, 14. Furthermore, it is fixed to the first support part 11. The partition wall 22 comprises a passage opening 22.2 to allow the first and second connecting parts 3.2, 4.2 to be arranged in the receiving device. The passage opening 22.2 is in the form of an outwardly opening through slot that runs through the entire thickness.

[0055] The openings 11.2, 22.2, 12.2 therefore form spaces for receiving the connecting ends 3.4, 4.4 of the first and second capsules 3,4.

[0056] Furthermore, a first actuation surface 8.1 is defined, comprising a first shell 8 and a first support part 11, and a second actuation surface 9.1, comprising a second shell 9 and a second support part 12. Each actuation surface 8.1, 9.1 is involved in the transmission of forces received by the receiving device 5 towards the first and second capsules 3, 4. This will be explained in more detail below.

[0057] joint According to the embodiment seen in Figures 2A, 2B, 3A, 3B, 5, the first and second shells 8, 9 are articulated relative to one another around the articulation axis 10 and between a receiving position (see Figures 2A, 2B, 3A, 3B), in which the first and second shells 8, 9 are separated from one another and the first and second capsules 3, 4 can be received in the first and second receiving sites 13, 14, respectively, and a connecting position (see Figures 4A, 4B), in which the first and second shells 8, 9 are brought together and the first and second capsules 3, 4 are pre-connected to one another. By pre-connected to one another it is meant that the male connecting end 4.4 of the second capsule 4 is partially introduced into the female connecting end 3.4 of the first capsule 3, but no sealed connection is established between the first and second capsules 3, 4. The first and second shells 8, 9 may for example have an inclination angle of 7° or more, for example about 7°, when they are in the receiving site and are substantially parallel to each other when they are in the connecting position. More specifically, there are only two main assemblies connected to each other: on the one hand, the first shell 8, the first support part 11, the partition wall 22, and on the other hand, the second support part 12, the second shell 9.

[0058] Advantageously, the first and second shells 8, 9 (or the actuation surfaces 8.1, 9.1) are configured to engage the first connecting part 3.2 with the second connecting part 4.2 when the receiving device 5 is moved into the closed position. Indeed, when the first and second shells 8, 9 are in the closed position, the connecting parts 3.2, 4.2 are partially coupled to one another.

[0059] The first and second support parts 11, 12 are more particularly configured such that the first and second capsules 3, 4 extend substantially parallel to one another when the first and second shells 8, 9 are in the connected position. As shown in Figures 4A, 4B, the first capsule 3 is configured to extend partially outside the receiving device 5 when it is received in the receiving device 5 and when the receiving device 5 is in the closed position. Advantageously, the outlet orifice 3.6 is configured to extend outside the receiving device 5 when the first capsule 3 is received in the receiving device 5 and when the receiving device 5 is in the closed position.

[0060] heating element The manufacturing device 2 comprises a heating element 46 (also called "heater element"), which can be seen in Fig. 3A, Fig. 3B. In the embodiment shown in the figures, the heating element 46 is part of the receiving device 5. However, if there is no receiving device 5, the receiving device 5 could be integrated into the mixer. The heating element 46 is attached to the partition wall 22. During the design, it has been chosen that the heating element 46 is present on the side of the first support part 11, which means that the heating element 46 is attached to the side of the partition wall 22, which is the side of the first support part 11. The heating element 46 preferably comprises one or more electric heating resistors 46.1 and a diffusion plate 46.2. The heating element 46 therefore has a planar shape for better diffusion of heat and, if possible, has a diameter of at least 500 mm. 2 , preferably 800 mm 2 However, since the first support part 11 is between the first capsule 3 and the heating element 46, a communication opening 46.3 is provided in the first support part 11, putting the plane 3.7 of the first capsule 3 in direct communication with the heating element 46 (i.e. separated only by air).

[0061] Heating element electrical contact tracks The heating element 46 needs to be supplied with electricity. Preferably, the receiving device 5 does not itself include a battery and must be supplied with power when the receiving device 5 is inserted into the receiving housing 32. As a result, an electrical connection is provided between the receiving device 5 and the mixer 6.

[0062] The receiving device 5 comprises an insertion face, where the openings 8.2, 9.2 are located, which is the face at which the receiving device 5 first enters the receiving housing 32, and an opposing withdrawal face, which is the face that is visible when the receiving device 5 is inserted into the receiving housing 32. The receiving device 5 further comprises a first working face 8.1 and an opposing second working face 9.1. Finally, the receiving device 5 comprises a first connecting face 23 and a second connecting face 24, which are preferably opposite each other. In the embodiment shown in Figures 2A, 2B, 3A, 3B, 4A, 4B, the connecting faces 23 and 24 correspond to the sides of the heating element 46 and are therefore different from the first and second working faces 8.1, 9.1 and the insertion / removal faces. The connecting faces 23, 24 extend between the working faces 8.1, 9.1 of the receiving device 5. Preferably, the connection surfaces 23, 24 connect the working surfaces 8.1, 9.1 of the receiving device 5 to one another, ie the connection surfaces 23, 24 are adjacent.

[0063] The general shape of the receiving device 5 is selected such that the connection faces 23, 24 are further away from each other than the actuation faces 8.1, 9.1 (and than the insertion / removal faces). In other words, if the smallest parallelepiped into which the receiving device 5 is inserted is taken into account, the faces in contact with the connection faces 23, 24 are further away than the faces in contact with the actuation faces 8.1, 9.1 and closer together than the faces in contact with the insertion / removal faces. This results in the fact that the receiving device 5 is wider than it is thick (and also taller than it is wide).

[0064] The first connecting surface 23 comprises a first electrical contact track 23.1, intended to supply the heater element 46, and the second connecting surface 24 comprises a second electrical contact track 24.1, also intended to supply the heating element 46 (FIGS. 2A, 3A, 3B, 4A, 4B). The electrical contact tracks 23.1, 24.1 are therefore on the outside of the receiving device 5 so as to be brought into contact with complementary tracks (FIGS. 2A, 4A, 4B).

[0065] This configuration has several advantages, firstly it ensures a simple and efficient electrical connection, and also avoids the risk of short circuits. Indeed, in the presence of liquid flowing inside the receiving housing 32 (for example shower or sink water, or simply a capsule bursting), it is unlikely that the two electrical contact tracks 23.1, 24.1 will be simultaneously affected by the same liquid volume.

[0066] The first connecting surface 23 comprises a section of the first and second shells 8, 9, of the first support part 11 and of the partition wall 22. In particular, the first connecting surface 23 comprises a longitudinal groove 23.2 with a bottom 23.21 and two side walls 23.22, 23.23. The first electrical contact track 23.1 is preferably arranged in the side wall 23.22 of the longitudinal groove 23.2. In the embodiment shown in Fig. 3A, Fig. 3B, the bottom 23.21 and the side wall 23.23 are formed by a section of the first support part 11. Then, a suitable cutout 8.5 is provided in the first shell 8, leaving a place for the longitudinal groove 23.2. The opposing side wall 23.22 is formed by a part of the partition wall 22. The first electrical contact track 23.1 is then arranged on this side wall 23.22 (for the heater element 46 to be attached to the partition wall). Likewise, a similar longitudinal groove 24.2 is provided on the second connecting surface 24 and comprises a cut-out 9.5 in the second shell 9, a bottom 24.21 and two opposite side walls 24.22, 24.23. Due to the non-central alignment of the groove, the cut-out 9.5 in the second shell 9 is made significantly less noticeable than the cut-out 8.5 in the first shell 8.

[0067] The grooves 23.2, 24.2 are arranged to engage (slidingly couple) with respective complementary rails 31.1, 31.2 provided on the receiving housing 32 on the connecting (preferably opposite) side (FIGS. 1A, 7A). As a result, the grooves 23.2, 24.2 form clearance surfaces which extend over the entire height of the section of the receiving device 5 in which they are arranged, at least up to the insertion height. The complementary rails 31.1, 31.2 contribute to the definition of the receiving housing 32 and are arranged on opposite edges.

[0068] In one embodiment, particularly seen in Figures 4A, 4B, the electrical contact tracks 23.1, 24.1 are not located at the same height but are offset.

[0069] The electrical contact tracks 23.1, 24.1 may take several forms, such as electrical pins, metal foils (as shown), etc. The electrical contact tracks 23.1, 24.1 are preferably slightly deformable to ensure a lasting contact when the receiving device 5 is placed in the receiving housing 32.

[0070] It is therefore noted that the longitudinal grooves 23.2, 24.2 are not centered with respect to the first and second working faces 8.1, 9.1 (see in particular Figs. 2A, 4A, 4B). In terms of design, this results in grooves essentially formed in the first support part 11 and in the first protective shell 8. The interest of this asymmetry lies in the foolproof function. In fact, it is not possible to place the receiving device 5 in the wrong orientation (following a rotation of 180° about the longitudinal axis X) since the grooves 23.2, 24.2 would not fit into the rails 31.1, 31.2 and the second shell 9 would abut against them.

[0071] In order to have a foolproof effect against vertical rotation (i.e. by trying to place first on the withdrawal face instead of the insertion face), the longitudinal grooves 23.2, 24.2 do not extend over the entire height of the section of the first or second shell 8, 9 in which they are placed. As a result, without necessarily providing a specific section, the abutment effect is simply obtained by a non-penetrating part of the first or second shell 8, 9 due to the clearance action. In other words, the first or second shell 8, 9 prevents the insertion of the grooves 23.2, 24.2 into the rail 31.1, 31.2 when the receiving device 5 is in the wrong orientation.

[0072] Furthermore, the longitudinal grooves 23.2, 24.2 each include an end abutment 23.3, 24.4 arranged on the side of the release face, which acts as an insertion abutment and defines the maximum insertion position in the receiving housing 32.

[0073] In reality, the end abutments comprise two different types of abutments, but they are located at substantially the same place, at the ends of the longitudinal grooves 23.2, 24.2.

[0074] Temperature sensor electrical contact track The first support part 11 is more convenient than the second support part 12 to carry the walls 23.23, 24.23 of the grooves 23.2, 24.2 by means of a heater element 46 intended mainly to heat the first capsule 3. In fact, a temperature sensor (not visible in the figures) is adjoined to the rear side of the diffusion plate 46.2 in order to measure the temperature prevailing in the vicinity of the first receiving site 13 and therefore of the first capsule 3. The temperature sensor is usually an NTC (negative temperature coefficient) thermistor. This temperature sensor must also be electrically connected to the mixer 6 (in particular to the processor, ultimately, to obtain the data) and to a battery 44 which accompanies the mixer 6 in order to supply it with power. For this purpose, a first additional electrical contact track 46.51 is provided at the level of the first contact surface 23. This first additional electrical contact track 46.51 is different from the first electrical contact track 23.1. More specifically, a first additional electrical contact track 46.51 is provided in the side wall 23.23, i.e. in the side wall formed by the first support portion 11, in the first groove 23.2.

[0075] Similarly, a second additional electrical contact track 46.52 is provided in the second groove 24.2.

[0076] The two additional electrical contact tracks 46.51, 46.52 are also advantageously offset: in a particular example, the additional electrical contact track 46.51 and the electrical contact track 24.1 are at the same height and the additional electrical contact track 46.52 and the electrical contact track 23.1 are at the same height.

[0077] Figures 2A, 3A, 3B, 4A, 4B and 5 show these tracks.

[0078] Foolproof The receiving device 5 comprises a foolproof 17 to ensure that the first and second capsules 3, 4 are correctly positioned, i.e. that the "correct" capsules 3, 4 are placed in the "correct" receiving sites 13, 14 (see clearly in Fig. 2A, Fig. 5). The foolproof 17 is preferably arranged at the end of the passage openings 11.2, 12.2 and blocks the undesired passage of the undesired connection ends 3.2, 4.2. The foolproof 17 comprises at least one flap 17.1 that opens outwardly of the receiving device 5 (preferably two on each side, as shown in the figures, preferably the two flaps 17.1 have a saloon structure, i.e. a structure that is articulated by a hinge outwardly of the receiving device 5). In particular, the foolproof 17 fulfills two different roles. The flap 17.1 comprises an opening 17.2 of a shape complementary to the female connecting end 3.4 of the first capsule 3 in order to allow the insertion of the first capsule 3 into the opening 8.2. Furthermore, the flap 17.1 comprises an abutment 17.3 which contributes to the definition of the opening 17.2 in order to prevent the insertion of the second connecting part 4.2, which is laterally longer than the first connecting part 3.2, into the opening 8.2. In fact, if there is an attempt to insert the second capsule 4 into the first receiving site 13, the end of the second connecting part 4.2, i.e. a part of the male connecting end 4.4, hits the abutment 17.3. For access to the second receiving site 14, which the foolproof 17 blocks when the receiving device 5 is in the closed position, the passage opening 12.2 is preferably also blocked by the abutment 17.3. On the other hand, when the receiving device 5 is in the open position, ie when the second shell 9 has been rotated on its hinge, the passage opening 12.2 is freed.

[0079] Finally, the flap 17.1 opens outwardly so that during withdrawal of the first and second capsules 3, 4 from the receiving device 5 (simultaneously, since both are attached), the flap is functionally unblocked.

[0080] The foolproof 17 may be attached to the first support part 11 or to the second support part 12 (as shown) depending on the design of the relative movement of the parts, if the second support part 12 is attached to the second shell (and therefore is rotationally movable relative to the first support part 11), then it is preferred that the foolproof is attached to the first support part 11. In other words, this is not critical.

[0081] A return spring 17.4 holds the foolproof 17 in the default, ie closed, position.

[0082] Pressing element - Wing member In particular, as shown in Figures 2B, 3A and 3B, the receiving device 5 further includes a first pressing element 19 configured to penetrate into the inside of the second receiving area 14, i.e. to apply pressure to the first capsule 3, more specifically to the first deformable section 3.1, and a second pressing element 21 configured to penetrate into the inside of the first receiving area 13, i.e. to apply pressure to the second capsule 4, more specifically to the second deformable section 4.1.

[0083] The first pressing element 19 (respectively, the second pressing element 21) is preferably attached to the first support part 11 (respectively, the second support part 12) and is movable between an inoperative position or so-called deployed position (see Figures 2B, 3A, 3B) in which the first or second receiving site 13, 14 is accessible to the first or second capsule 3, 4, and an operative position or so-called folded position in which the first pressing element 19 (respectively, the second pressing element 21) penetrates into the first receiving site 13 (respectively, the second receiving site 14), i.e. it can apply pressure to the first deformable section 3.1 of the first capsule 3 (respectively the second deformable section 4.1 of the second capsule 4). The first pressing element 19 (respectively the second pressing element 21) is advantageously mounted rotatably about a hinge 19.1 (respectively the hinge 21.1). The hinge 19.1 (respectively the hinge 21.1) is arranged opposite the opening 8.2 (respectively the opening 9.2) of the first shell 8 (respectively the second shell 9). Thus, both hinges 19.1, 21.1 are arranged near the release face of the receiving device 5.

[0084] The pressing elements 19, 21 each have a flat inner surface 19.2, 21.2 for forming a rotatably movable wing member. Each flat inner surface 19.2, 21.2 cooperates with the first or second capsule 3, 4, respectively. When the pressing element is pressed, the volume between the wing member and the arrangement surface 11.1, 12.1 is gradually and continuously reduced. When the first or second capsule 3, 4 is installed, the outlet orifice 3.6 and the connecting part 3.2, 4.2 are located on the opposite side of the hinge 10, which allows for an effective discharge of the cream from the first or second capsule 3, 4, while avoiding any unnecessary retention area inside.

[0085] In order to keep the pressure elements 19, 21 in the open position by default (i.e. when the receiving device 5 is not actuated or when the second shell 9 is in the pivoted position), return means 21.3, such as a spring, are provided, pressing against the first or second shell 8, 9 (FIG. 5). The return means 21.3 may tend to press against a wing member extending slightly to the other side of the hinge 21.1.

[0086] In use, as described below, the two pressing elements 19, 21 are successively activated, allowing the kneading of the cream, which then passes from the first or second capsule 3, 4 to the other second or first capsule 4, 3.

[0087] Preferably, in order to optimize the movement of the wing members, the hinge 19.1 (respectively, hinge 21.1) defines an axis of rotation that is included in the plane of the arrangement surface 11.1 (respectively, arrangement surface 12.1) and perpendicular to the longitudinal axis of the receiving device 5. In the absence of a capsule, the inner surface 19.2, 21.2 may be pressed against the arrangement surface 11.1, 12.1. Similarly, the hinge 19.1, 21.1 is preferably located just at the end of the first or second receiving site 13, 14.

[0088] To move the pressing elements 19, 21, the first and second shells 8, 9 each include a pressing point 8.3, 9.3, preferably facing the tip portion of the wing member (to take advantage of the leverage effect and minimize the applied force), configured to receive an external force, as will be explained in more detail below. The pressing point 8.3, 9.3 is attached to a deformable flexible area 8.4, 9.4 (made of elastomer or the like), which is itself attached to the remaining part of the first or second shell 8, 9, which is made of a more rigid plastic. The pressing point 8.3, 9.3 is made of a rigid material (usually plastic). Alternatively (not shown), the first and second shells 8, 9 have two orifices, preferably facing the tip portion of the wing member, to allow free access to the pressing elements 19, 21.

[0089] The user may hold the receiving device 5 in one hand and press simultaneously on the pressure points 8.4, 9.4, for example with the thumb and index / middle finger. The simultaneous pressure allows the cream to be directed from the first and second capsules 3, 4 towards the exit orifice 3.6.

[0090] In another embodiment, not shown, where the receiving device 5 is integrated into the mixer 6 , the wing members may be integrated directly into the mixer 6 .

[0091] Holding contact part In order to prevent the receiving device 5 from being pulled out of the receiving housing 32 during the course of the mixing method, a retaining mechanism 50, which will be described in detail below, is provided on the production device 2. In order for the retaining mechanism 50 to grip the receiving device 5, a retaining abutment 9.6 is provided on one of the first or second shells 8, 9 (the second shell 9 in Figs. 2A, 2B, 3A, 3B, 4B, 5). This retaining abutment 9.6 essentially corresponds to a projection extending radially, i.e. in a plane perpendicular to the longitudinal direction X. It can be found at any position along the height of the receiving device 5. In the illustrated exemplary embodiment, the retaining abutment 9.6 is located near the insertion surface. Another abutment can be provided on the other shell, for example for ergonomic reasons.

[0092] Grasping Handle To enable a user to grasp the receiving device 5 when it is inserted into the receiving housing 32, gripping handles 8.7, 9.7 are provided on each of the first and second protective shells 8, 9 (see in particular Figures 1, 2B, 4A, 4B). These gripping handles 8.7, 9.7 are arranged at the height of the release surface, which is an accessible height when the receiving device 5 is in place.

[0093] The grip handles 8.7, 9.7 may simply consist of a protrusion extending radially, ie in a plane perpendicular to the longitudinal direction X, long enough that some of the user's phalanges can pull on it.

[0094] Combine Button As mentioned above, the actuation surfaces 8.1, 9.1, and more particularly the first and second protective shells 8, 9, respectively, comprise pressure points 8.3, 9.3 for transmitting forces inwards towards the pressure elements 19, 21. These pressure points 8.3, 9.3 are formed in flexible areas 8.4, 9.4.

[0095] When the receiving device 5 is switched to the closed position, the connecting ends 3.4, 4.4 face each other and partially interlock. In order to generate a sealed and reliable fluid communication between the first and second capsules 3, 4, a coupling mechanism 52 is provided on the manufacturing device 2. This coupling mechanism 52 exerts a force in the direction of the receiving device. This coupling mechanism 52 makes it possible both to establish a fluid connection between the first and second capsules 3, 4 under the influence of the force exerted by the coupling mechanism 52, but also to avoid any undesired detachment of the first and second capsules 3, 4 under the influence of the pressure generated by the kneading of the first and second capsules 3, 4. It will be explained below.

[0096] One (or both) of the first or second protective shells 8, 9 comprises a coupling button 9.8, which is movable in the direction of the second receptor site 14 (FIGS. 2A, 2B, 3A, 3B, 4A, 4B, 5). More specifically, the coupling button 9.8 is intended to press the second capsule 4 near the connection section 4.2, so that it is movable in the direction of the area close to the opening 9.2. In this regard, the coupling button 9.8 is attached to a flexible area, which may be the flexible area 9.4 of the pressing point 9.3. It is noted here that the coupling button 9.8 is separate from the pressure point 9.3. The coupling button 9.8 is preferably rigid in order to transfer well the force of the coupling mechanism 52 to the first and second capsules 3, 4 so that they remain coupled.

[0097] mixer More specifically, as shown in Figures 6, 7A, 7B, 8A, 8B, 8C, 9, 10A, 11A, 11B, 11C, the mixer 6 includes a support 31 and a receiving housing 32 at least partially defined by the support 31 and configured to receive at least a part of the receiving device 5. According to the embodiment shown in Figures 1A, 1B, the mixer 6 and the receiving device 5 are configured such that when the receiving device 5 is received in the receiving housing 32, the receiving device 5 at least partially extends outside the mixer 6. The support 31 behaves like a base, i.e., the support 31 defines a set of fixing elements when the mixer 6 is placed on a support (table, countertop, etc.), regardless of whether the mixer 6 is in use or not. The support 31 of the mixer 6 also includes an outer shell 33 and an insertion opening 34 that opens into the receiving housing 32, and the receiving device 5 is configured to be inserted into the receiving housing 32 through the insertion opening 34. Advantageously, the insertion opening 34 is located in a central portion of the upper surface of the outer shell 33 and configured to be oriented upwards when the mixer 6 is placed on a horizontal supporting surface (table, countertop, etc.). The outer shell 33 also serves as an outer casing with a desired design for the mixer. The outer shell 33 may include a lower base and an upper base.

[0098] Actuation system The mixer 6 further comprises an actuation system 35 pivotally mounted on the support 31 about a pivot axis 36 which is substantially vertical when the mixer 6 is placed on a horizontal support surface (table, countertop, ...) (Figs. 6, 8A, 8B, 8C, 9, 10A). Preferably, the actuation system 35 performs a reciprocating movement about the pivot axis 36 along a maximum angular displacement of 45°. The movement thus consists of a rotation at +45° maximum, then a rotation at -45°, etc. The movement takes place along a nominal stroke C35 (not shown), which is associated with a maximum angular displacement in case of a rotation about the pivot axis 36. The nominal stroke C35 of the actuation system 35 is defined as the stroke between the two farthest positions of the actuation system 35. The neutral position of the actuation system 35 is defined between these two farthest positions, and the neutral position of the actuation system 35 corresponds to the insertion position in which the receiving device 5 can be placed inside the receiving housing 32 of the mixer 6 without being obstructed by the actuation system 35.

[0099] The mixer 6 further includes a drive motor 39 mounted to the support 31. The drive motor 39 is configured to pivot the actuation system 35 about the pivot axis 36 within a predetermined angular range. Preferably, the drive motor 39 rotates in only one direction.

[0100] The actuation system 35 comprises a first actuation member 37, which may include a first actuation finger 37.1, configured to transmit a pressing force to the first capsule 3, and a second actuation member 38, which may include a second actuation finger 38.1, facing the first actuation member 37, configured to transmit a pressing force to the second capsule 4. The first and second actuation members 37, 38 are configured to be arranged on either side of the receiving housing 32, and thus on either side of the receiving device 5, when the receiving device 5 is received in the mixer 6, more specifically in the receiving housing 32. The actuation members 37, 38 have at least one position in which they are at least partially inside the receiving housing 32. In a neutral position of the actuation system 35, the actuation members 37, 38 are arranged relative to the receiving housing 32 so as to allow the receiving device 5 to be placed in the receiving housing 32 of the mixer 6, which is the insertion position.

[0101] The first and second actuating members 37, 38 are more particularly configured to apply pressure, respectively and alternately, to the first and second pressing elements 19, 21 in order to transmit pressure, respectively and alternately, to the first and second compartments 3.1, 4.1. In particular, the first and second actuating members 37, 38 are configured to cooperate with the first and second pressing points 8.3, 9.3 of the first and second protective shells 8, 9, respectively, or directly with the pressing elements 19, 21.

[0102] An actuation stroke C37 is defined for the first actuation member 37 and an actuation stroke C38 is defined for the second actuation member 38. The actuation stroke C37 is defined as the stroke of the first actuation member 37 between a neutral position of the actuation system 35 and a maximum actuation position of the first actuation member 37, in which the first actuation member 37 is in a maximum compression state relative to the first pressing element 19. Conversely, the actuation stroke C38 is defined as the stroke of the second actuation member 38 between a neutral position of the actuation system 35 and a maximum actuation position of the second actuation member 38, in which the second actuation member 38 is in a maximum compression state relative to the second pressing element 21.

[0103] Preferably, the movement of the actuation system 35 can be tracked using various sensors, in particular Hall effect sensors. More specifically, each of the first actuation member 37 and the second actuation member 38 can include a magnet intended to interact with a fixed Hall effect sensor. Advantageously, the Hall effect sensor can be arranged directly on the monitoring unit 45, which will be described later, as seen in FIG. 12. The monitoring unit 45 is thus able to track the movement of the actuation system 35 and also of each of the first and second actuation members 37, 38. It can even be envisaged that the monitoring unit 45 knows exactly the position of each of the first and second actuation members in their respective actuation strokes C37, C38, for example by arranging several Hall effect sensors.

[0104] According to the embodiment represented in FIGS. 1 to 22, the first and second actuating members 37 , 38 extend substantially in the same extension plane and converge oppositely to the pivot axis 36 .

[0105] As shown in Figures 6, 8A, 8B, 8C, 9, the actuation system 35 has a substantially annular shape that defines an opening around the receiving housing 32. In one embodiment, the actuation system 35 is essentially formed in one piece and includes an opening for receiving a shaft that defines the pivot axis 36. A first actuation member 37 and a second actuation member 38 are disposed on opposite sides of the actuation system 35. As a result, there are two actuation members 37, 38, openings for the pivot axis 36, and grooves, which will be described later, that extend over twice the two opposite sides of the actuation system 35.

[0106] The actuating members 37, 38 may each comprise a drive support 37.3, 38.3 which meet on one side at the level of the pivot axis 36. On the opposite side a connection section 36.1 is defined which connects the two drive supports 37.3, 38.3. The connection section 36.1 may be attached or formed integrally with the drive supports 37.3, 38.3.

[0107] Preferably, the two actuating members 37, 38 rotate about the same pivot axis 36. In this case, two drive supports 37.3, 38.3 fixed in rotation are advantageous.

[0108] However, it would be possible to provide each of the actuating members 37, 38 with a pivot axis, only some simple modifications would need to be made.

[0109] Alternatively, in one embodiment not shown, the actuation member is translatable.

[0110] Spring The actuation system 35 moves along a nominal stroke C35 to apply a force to the receiving device 5. Nevertheless, the clearances of the kinematic chain, which are related to manufacturing tolerances, can cause the actuation system 35 to shift its alignment and thus interfere with the transmission of the force. Thus, at the end of the stroke, it may be missing a few millimeters or, conversely, exceeding a few millimeters. This can result in insufficient compression or, conversely, destruction of the production device 2.

[0111] To overcome that, the actuation system 35 may include springs 37.4, 38.4 (see in particular in Figures 8A, 8B, 8C). In particular, the springs 37.4, 38.4 are configured to be compressed when the actuation system 35 reaches near its nominal end of the stroke C35 and when the actuation fingers 37.1, 38.1 abut against the planes 3.7, 4.7 of the capsule. The springs 37.4, 38.4 thus generate a force tending to move the actuation members 37, 38 away from the receiving device 5.

[0112] More specifically, each actuating member 37, 38 includes a spring 37.4, 38.4.

[0113] The springs 37.4, 38.4 may be located in a variety of locations. In one embodiment, not shown, the springs 37.4, 38.4 are located at the "free" ends of the fingers 37.1, 38.1.

[0114] In other embodiments, the springs are hidden, so that the springs 37.4, 38.4 are preferably mounted between the fingers 37.1, 38.1 and the drive supports 37.3, 38.3. In this way, the springs are not accessible to the user, as they are hidden in the base. To place the springs in this position, it is convenient to provide for each actuating member 37, 38 an arm 37.2, 38.2, which is movably mounted with respect to the drive supports 37.3, 38.3. The fingers 37.1, 38.1 are then fixedly attached to the arms 37.2, 38.2. In particular, in the embodiment shown in Figures 8A, 8B, 8C and 9, the arms 37.2, 38.2 are rotatably movable with respect to the drive supports 37.3, 38.3 by means of hinges 37.5, 38.5. The springs 37.4, 38.4 are arranged between the arms 37.2, 38.2 and the drive supports 37.3, 38.3.

[0115] Thus, the spring 37.4, 38.4 works in compression, in the sense that its idle or unstressed position is not compressed. It is compressed in the direction of movement or rotation of the actuating members 37, 38.

[0116] The spring 37.4, 38.4 may be a helical or leaf spring, or it may even comprise a resilient material or assembly (elastomer, foam, etc.).

[0117] Rotational drive According to the embodiment shown in Figures 6, 8A, 8B, 8C and 9, the mixer 6 also comprises a cam 41 in the form of a drive wheel or drive arm fixed in rotation to the output shaft 39.1 of the drive motor 39 and adapted to be driven in rotation about its rotating camshaft 41.1. The cam 41 is mounted on the support 31. Preferably, the pivot shaft 36 and cam 41 are on either side of the receiving housing 32 to permit reciprocating motion with a large lever arm.

[0118] The cam 41 is provided with a drive finger 42 which is eccentric with respect to the rotating camshaft 41.1.

[0119] The cam 41 is typically driven by a drive motor 39 using one or more belts. In this case the kinematic chain goes from the drive motor 39 and its output shaft 39.1 with the pulley attached to it, to the belt 39.2, to the pulley 39.3 connected by a shaft to the pulley 39.4, to the belt 39.5, to the cam 41.

[0120] The drive finger 42 is received in a drive groove 43 provided in the actuation system 35. In particular, the drive groove 43 is located in the connection 36.1. The drive groove 43 is elongated and extends along a direction of extension substantially parallel to the pivot axis 36. Such a configuration of the mixer 6 makes it possible to obtain a reciprocating movement of the actuation system 35 by rotating the drive motor 39 always in the same rotational direction, without having to resort to an expensive control system of the drive motor 39. The drive groove 43 extends along its depth in the direction of the pivot axis 36.

[0121] Next, the connection between the drive groove 43 and the drive finger 42 will be explained. By rotation of the actuating member 35, the alignment of the drive groove 43 and the drive finger 42 is variable, which means that a simple adjustment would block the system. Conversely, the presence of clearances that allow misalignment would generate noise and create lag times at each end of the stroke.

[0122] To remedy this, a ball joint is provided between the drive finger 42 and the drive groove 43, which makes it possible to manage such misalignment.

[0123] In particular, a ball 42.1 housed in a ring 43.1 is attached to the drive finger 42. The connection between the ball 42.1 and the ring 43.1 is a ball joint. The ring 43.1, for its part, is received in the drive groove 43 and is mounted there so as to be translationally movable along a direction parallel to the pivot axis 36 (and therefore along the length of the drive groove 43). Finally, the ball 42.1 is mounted so as to be translationally movable along the drive finger 42. The arrangement of these different connections may differ in that the ring is also translationally movable along the depth of the groove and the ball is then fixed to the drive finger. As a result, the complete connection between the drive finger 42 and the actuation system 35 includes in series a slide, a ball, a slide perpendicular to the other slide. It is therefore noted that in a kinematic torsor, forces can only be transmitted to one of the six components of the torsor, namely the translational component that is tangent to the rotational movement of the actuation system 35, i.e. the component that makes it possible to rotate the actuation system 35. The kinematic equivalent is the sphere-plane link (also called a point link).

[0124] In order not to make the above connection unnecessarily more complicated, the cam rotation axis 41.1 and the pivot axis 36 are preferably perpendicular. This makes it possible to have the drive finger 42 describe a circular motion in a plane parallel to the pivot axis 36.

[0125] Some planned movements of the connection can be easily carried out by means of plastic / plastic slides, the wear of which is sufficiently slow to ensure a satisfactory service life.

[0126] According to one variant of the invention, the mixer 6 could be configured such that rotation of the drive motor 39 in a first rotational direction results in pivoting of the working part 35 in a first pivot direction, and rotation of the drive motor 39 in a second rotational direction opposite to the first rotational direction results in pivoting of the working part 35 in a second pivot direction opposite to the first pivot direction.

[0127] Pivot shaft eccentricity The actuating members 37, 38 move along actuating strokes C37, C38, respectively. However, in the embodiment shown in the figures, one of the two actuating members 37, 38 has an actuating stroke C37, C38 of a length that is by far greater than that of the other actuating member. This difference in the actuating strokes C37, C38 allows a better mechanical and electrical management of the forces provided to deform the first capsule 3 compared to the second capsule 4. Indeed, as shown in FIG. 2B, the first capsule 3 has a greater thickness than the second capsule 4, which means that more space is required on the side of the thickest capsule and the push element 19 will come into contact more quickly and start to actuate faster than the push element 21.

[0128] To achieve this stroke difference, several solutions can be considered. One solution consists in having an offset drive groove 43 in the connection section 36.1. Another solution, in particular shown in Fig. 8A, 8B, 8C, 9, consists in making the pivot axis 36 eccentric. In other words, the cam rotation axis 41.1 does not intersect with the pivot axis 36. This causes a stroke difference between the two actuating members 37, 38 when the cam 41 makes a full revolution. A distance between the cam rotation axis 41.1 and the pivot axis 36 (orthogonal, i.e. by orthogonal projection) of 1% to 5% of the distance between the drive groove 43 and the pivot axis 36 is satisfactory and does not disturb too much the symmetrical appearance of the assembly. As an absolute value, a distance comprised between 1 and 2 mm is suitable. The eccentricity can also be defined with the receiving housing 32 relative to the rotation axis of the cam 41, so that the farthest position of the actuating system 35 is not centered on the receiving housing 32. The eccentricity can also be defined relative to the first and second arrangement surfaces 11.1, 12.1 or relative to the position of the first and second capsules 3, 4 in the receiving housing 32 using the planes 3.7, 4.7, which thus define a pseudo-plane in the receiving housing 32. The maximum distance from the first actuating member 37 to said plane of the plane 3.7 is greater than the maximum distance from the second actuating member 38 to the plane 4.7. In this regard, in one variant, the pivot axis 36 is included in a plane located equidistant from the two arrangement surfaces 11.1, 12.1.

[0129] Corresponding to the eccentricity, the first actuating finger 37.1 is advantageously longer than the second actuating finger 38.1. This is in particular due to the fact that it is necessary to compensate for the furthest position of the actuating fingers 37.1, 38.1 due to the eccentricity. More precisely, the actuating finger 37.1, 38.1 operating on the thickest first or second capsule 3, 4 has a greater length than the other actuating fingers 38.1, 37.1.

[0130] Another solution, shown in Fig. 8A, consists in not defining a neutral position of the actuation system 35 between the top or bottom dead center of the cam 41. In fact, by choosing a neutral position of the actuation system 35 at a non-zero angle Ag (usually Ag is comprised between 5° and 30°) relative to noon (when the mixer 6 is placed on a horizontal support), the distribution of the actuation strokes C37, C38 is offset. Moreover, it is noted that another neutral position is virtually obtained for the angle Ag', which corresponds to Ag'=180°-Ag. In fact, the actuation strokes C37, C38 correspond to a rotation, with respect to the cam 41, from said angle Ag to exactly 90° rotation (i.e. when the mixer 6 is at 3 o'clock or 9 o'clock when it is placed on a horizontal support) and then to a rotation of 270° from the angle Ag'. It is immediately recognized that the strokes C37 and C38 are not equal, since Ag and Ag' are not at 0° and 180° (noon and 6 o'clock). Thus, in a complete revolution of the cam 41, the first working stroke C37 is in the first direction, then the first working stroke C37 is in the second direction, then the second working stroke C38 is in the first direction, then the second working stroke C38 is in the second direction, i.e. it covers twice the nominal stroke C35.

[0131] Blender Contact Track As mentioned above, the mixer 6 also includes electrical contact tracks 31.11, 31.12 configured to engage with the electrical contact tracks 23.1, 24.1 of the longitudinal grooves 23.2, 24.2 of the receiving device 5, and electrical contact tracks 31.51, 31.52 configured to engage with further electrical contact tracks 46.51, 46.52 of the longitudinal grooves 23.2, 24.2.

[0132] These electrical contact tracks are mounted on rails 31.1, 31.2 (FIGS. 1A, 7A) which are fixed to the support 31 and attached to the two connection sides of the receiving housing 32. The positions of the electrical contact tracks 31.11, 31.12 (and also 31.51, 31.52) on the rails 31.1, 31.2 are complementary to the positions of the electrical contact tracks 23.1, 24.1 (and also 46.51, 46.52) on the connection faces 23, 24 of the receiving device 5. The rails 31.1, 31.2 contribute to defining the receiving housing 32. They are arranged, for example, at the ends and are preferably fixed to the support 31 over their entire length.

[0133] The position of the electrical contact tracks 31.51, 46.51 and 31.52, 46.52 on two opposing rails 31.1, 31.2 arranged at a distance from each other has the advantage of limiting the risk of short circuits in case gravity causes a liquid to flow onto one of the rails 31.1, 31.2.

[0134] Shutter, coupling, extraction mechanism The mixer 6 further includes a holding mechanism 50, a coupling mechanism 52, and a clamping mechanism 54 (FIGS. 10A, 10B, 10C, 10D, 10E, 10F, 11A, 11B, 11C). Each of these mechanisms has a specific, independent function. However, they can be advantageously driven simultaneously by the same auxiliary motor 40.

[0135] The retaining mechanism 50 has the function of preventing the removal of the receiving device 5 when mixing is in progress. The retaining mechanism 50 is movably mounted with respect to the support 31 between an insertion position and a holding position. In the insertion position, the retaining mechanism 50 allows the insertion and withdrawal of the receiving device 5 from the mixer 6. In the holding position, the retaining mechanism 50 blocks the withdrawal of the receiving device 5 (and would therefore prevent its insertion). Between the two aforementioned positions, the retaining mechanism 50 comprises a mobile element 50.1, which in the holding position extends into the receiving housing 32. In particular, in the holding position, the mobile element 50.1 cooperates with the retaining abutment 9.6 to prevent a translational movement of the receiving device 5 aimed at withdrawing it from the mixer 6 (indeed, the retaining abutment 9.6 is blocked against the mobile element 50.1 in the case of withdrawal). In this regard, the mobile element 50.1 and the retaining abutment 9.6 are arranged so that when the receiving device 5 is placed in the mixer, they are located close to the retaining position, preferably less than 2 mm. In one embodiment shown in Fig. 10A, 10B, 10C, the mobile element 50.1 is a wheel, called a retaining wheel, which is movable around the wheel rotation axis 50.2. The wheel 50.1 has at least two different diameters, the smallest diameter being configured not to extend into the receiving housing 32 in the insertion position and the largest diameter being configured to extend into the receiving housing 32 in the retention position to come into contact with the retaining abutment 9.6 in case of withdrawal. The wheel 50.1 is preferably circular with a flat section, which allows the insertion position. The wheel 50.1 is mounted on a shaft extending along the wheel rotation axis 50.2. This shaft comprises a pinion 51 or pulley connected to at least another pinion or another pulley 51.1. Alternatively, the mobile element 50.1 can be translated, for example by means of a rack and pinion system via the pinion 51.

[0136] The coupling mechanism 52 has the function of establishing a sealed connection between the first and second capsules 3, 4 and ensuring that these capsules remain coupled via their connection ends 3.4, 4.4 by pressing the coupling button 9.8 of the second protective shell 9. The coupling mechanism 52 is movably mounted with respect to the support 31 between an insertion position and a coupling position. In the insertion position, the coupling mechanism 52 allows the insertion and withdrawal of the receiving device 5. In the coupling position, the coupling mechanism 52 locks the first and second capsules 3, 4. The coupling mechanism 52 comprises a coupling element 52.1 movable between the two aforementioned positions, which in the coupling position extends into the receiving housing 32. In particular, in the coupling position, the coupling element 52.1 cooperates with the coupling button 9.8 which moves inwardly into the second receiving site 14. In this respect, the coupling element 52.1 and the coupling button 9.8 are arranged facing each other when the receiving device 5 is placed in the mixer 6.

[0137] In one embodiment shown in Figures 10A, 10B, 10C, the coupling element 52.1 is a wheel, called a coupling wheel, movable about a wheel axis of rotation 52.2, which preferably coincides with the wheel axis of rotation 50.2. The wheel 52.1 has at least two different diameters, a smallest diameter configured not to extend into the receiving housing 32 in the insertion position and a largest diameter configured to extend into the receiving housing 32 in the coupling position in order to contact and press the coupling button 9.8. The wheel 52.1 is preferably elliptical in plane.

[0138] The wheel 52.1 is mounted on a shaft extending along the wheel rotation axis 50.2. This shaft comprises a pinion or pulley coupled to at least another pinion or another pulley 51.1. The shaft and pinion are preferably identical to the shaft and pinion 51. In this way, a first subassembly fixed in rotation is obtained. Alternatively, the coupling element 52.1 can be translationally movable, for example by means of a rack-and-pinion system by the pinion 51.

[0139] The coupling mechanism 52 is different from the actuation system 35. This results in different positions (e.g. different heights) within the mixer 6. Similarly, the receiving device 5 includes a number of press points 8.3, 9.3 that are different from the coupling button 9.8.

[0140] The clamping mechanism 54 has the function of blocking the outlet passage 3.5 of the first capsule 3 when the mixing method is in progress. Indeed, pressure in the first or second capsule 3, 4 could cause an undesired release of cream. This should be avoided, since in this case the cream would spill into the mixer 6. It is shown in figures 11A, 11B, 11C. The clamping mechanism 54 is movable relative to the support 31 between an insertion position and a clamping position. In the insertion position, the clamping mechanism 54 allows the insertion and withdrawal of the receiving device 5 carrying the first capsule 3. In the clamping position, the clamping mechanism 54 clamps the outlet passage 3.5. The clamping mechanism 54 comprises a clamping wheel 54.1, called clamping wheel, which is movable in rotation about a clamping wheel axis 54.2. The mixer 6 further comprises a fixed guide wall 54.3 (fixed to the support 31 and also formed integrally with it) along which the clamping wheel 54.1 rotates or slides, and a clamping wall along which it is clamped in the clamping position. The clamping wall is advantageously part of the guide wall 54.3. There are several variants, one in which the clamping wheel 54.1 approaches the guide wall 54.3 in the direction of the clamping position, one in which the distance is constant, or one in which the clamping wall has a specific recess for capturing the clamping wheel 54.1 (this is possible with a translatable clamping wheel 54.1, see below). The teeth 54.11 present on the clamping wheel 54.1 (in practice the wheel comprises a circular or substantially circular section, which clamps the first capsule 3, and preferably a toothed section below the circular section) may cooperate with the teeth 54.31 of the guide wall 54.3, the clamping wheel 54.1 rotating relative to the guide wall 54.3. Furthermore, due to the teeth 54.11, 54.31 the clamping wheel 54.1 has a rotational movement without sliding relative to the guide wall 54.3, which makes it possible to avoid sliding which would risk clamping the outlet passage 3.5 in error.Finally, by means of the teeth 54.11, 54.31, the distance between the clamping wheel 54.1 and the guide wall 54.3 (excluding the teeth, i.e. the standard distance) can be reduced to almost zero under the first capsule 3, while retaining a rotational movement relative to the guide wall 54.3. To allow this movement, the clamping wheel 54.1 is mounted, preferably rotationally movable, on an arm 54.5, which is itself rotationally movable about its axis of rotation 54.51. The arm 54.5 is fixed to a pinion (or pulley), or pinion section 54.52, which is itself connected to the common pinion 40.1 by various pinions or pulleys. As a result, the arms 54.5 are driven in rotation by the same auxiliary motor 40. To ensure clamping in the clamping position, including when the auxiliary motor 40 is not powered on, the clamping wheel 54.1 is mounted so as to be movable in translation in the radial direction along the arm 54.5. Return means 54.4 arranged between the clamping wheel 54.1 and the arm 54.5 tend to move the clamping wheel 54.1 away from the arm rotation axis 54.51, thus pressing the clamping wheel 54.1 against the guide wall 54.3. More specifically, an intermediate support is provided which carries the rotation axis 54.2 of the clamping wheel 54.1. It is this intermediate support which is translatable relative to the shaft 54.5. The sliding connection of the intermediate support with the pin 54.42, which slides in the groove 54.53 of the shaft 54.5, makes it possible to guide the translation and also advantageously to limit it. The return means 54.4 therefore operate in compression, as long as they are not (or hardly) compressed by default. A helical spring, a leaf spring or other type of spring may be suitable. The return means 54.4 allows the clamping wheel 54.1 to remain pressed against the guide wall 54.3 even though the distance between the guide wall 54.3 and the arm rotation axis 54.51 is variable (the distance may gradually decrease towards the area where the outlet passage 3.5 is located).

[0141] Common Drive Unit Preferably, the holding mechanism 50, the coupling mechanism 52 and the clamping mechanism 54 are driven simultaneously by a common drive, as described according to the following exemplary embodiment. The holding mechanism 50 is driven by a pinion 51, which is coupled to at least another pinion 51.1 (FIGS. 10A, 10B). The coupling mechanism 52 is driven by at least another pinion, preferably a pinion coupled to the pinion 51 and the other pinion 51.1 (FIGS. 10A, 10B). The clamping mechanism 54 is driven by a pinion section 54.52. Although different kinematic chains can be provided, a common pinion 40.1 is preferably provided, which in turn drives the other pinion 51.1 and the pinion section 54.52. As shown in FIG. 11A, FIG. 11B, FIG. 11C, the common pinion 40.1 is arranged on the output shaft of the auxiliary motor 40. It meshes directly with a pinion 51.1 mounted on a shaft containing another pinion 51.2. This pinion 51.2, for its part, meshes with a pinion section 54.52. The kinematic chain is therefore very simple, with a minimum of pinions and therefore minimal friction losses, minimal risk of breakage and almost no clearances.

[0142] By means of this common pinion 40.1 arranged on the output shaft of the auxiliary motor 40, at least two of the three aforementioned mechanisms 50, 52, 54 are simultaneously in the insert position or in the holding, coupling and clamping position. The same auxiliary motor 40 thus drives all three, which constitutes a major simplification of the mixer 6 and its operating logic.

[0143] Visual and audio display devices The mixer 6 advantageously includes a screen 60 and / or a loudspeaker making it possible to exchange information with the user (FIGS. 1A, 1B, 7). The screen 60 is preferably a touch screen, to avoid having to provide physical buttons. This allows the user to specify the start of the cycle and the time of withdrawal. The screen 60 may also indicate the end of the cycle, for example accompanied by an audible warning.

[0144] Power Supply and Monitoring Unit According to one embodiment of the invention, the mixer 6 also includes a power supply (not shown) configured to power the mixer 6, in particular the drive motor 39 and the auxiliary motor 40. The power supply advantageously or in fact includes at least one rechargeable battery 44 (FIG. 7B). In the example shown, the rechargeable battery 44 is advantageously constituted by a two-cell lithium-ion battery providing a nominal output voltage of 7.4V.

[0145] As shown in Fig. 12, the mixer 6 further comprises a monitoring unit 45, comprising for example a controller such as a microcontroller or a processor such as a microprocessor 45.1, arranged to monitor the operation of the production device 2, more particularly the drive motor 39, the auxiliary motor 40, the heating element 46, the temperature sensor and the screen 60 (in the latter case a processor is preferred), as well as any audio or visual devices. The monitoring unit 45 advantageously comprises a memory 45.2 of non-volatile type, which stores a sequence of instructions, in the form of a program executed by the controller or processor 45.1, in particular to carry out some steps described in the following method.

[0146] Other embodiments In one variant, the receiving device 5 is integrated into the mixer 6. The first or second capsule 3, 4 is thus inserted into the first or second receiving site 13, 14. A receiving housing 32 is defined which corresponds to the volume occupied by the receiving device 5. Furthermore, in this variant, the actuating surfaces 8.1, 9.1 may not be present, in which case the actuating members 37, 38 press directly against the first or second capsule 3, 4.

[0147] How to use Next, at least one method for producing a composition such as a cosmetic product using the production device 2 will be described. This production method may consist of several sub-methods (called "methods" for clarity), one or more variants of which will be described. A preliminary method Ep, an initialization method Ei, a mixing method Em and a recovery method Er are particularly distinguished. In particular, these methods (or their variants) are advantageously implemented using the different embodiments of the production device 2 described above. Preferably, most of the steps of the methods Ei, Em and Er are stored in a memory 45.2 of non-volatile type in the form of instructions of a sequence of codes that can be executed by the processor 45.1.

[0148] The preliminary method Ep includes a preliminary step Ep1 to any use of the manufacturing apparatus 2, consisting of connecting the manufacturing apparatus 2 to the mains power supply or recharging the battery 44. Furthermore, this preliminary step Ep1 can be preceded or followed by a step Ep2 of placing the manufacturing apparatus 2 on a flat support, possibly accompanied by a power-on step.

[0149] Then, the initialization method Ei is executed. In step Ei1 ("receiving step"), the processor of the manufacturing device 2 receives a start command. This start command is usually generated by a user action (contact with the touch screen 60, a push button, a switch, etc.). Following this step Ei1, in step Ei2 ("verifying step"), the method ensures that the actuation system 35 is in a neutral position, allowing the insertion of the receiving device 5 or the first and second capsules 3, 4. Typically, it must be ensured that the receiving housing 32 (for the insertion of the receiving device 5) or the first or second receiving sites 13, 14 (for the insertion of the first or second capsules 3, 4, in the absence of the receiving device 5) are not obstructed by the actuation system 35. During this step Ei2, it should also be verified that the clamping mechanism 54, the coupling mechanism 52 and the holding mechanism 50 are deactivated, i.e. in their respective insertion positions. Following this step Ei2, it is possible to insert the receiving device 5 containing the first or second capsule 3, 4 manually or even to insert the first or second capsule 3, 4 directly into the receiving housing 32. Finally, in a next step Ei3 ("closing step"), at least one of the clamping mechanism 54, the coupling mechanism 52, the holding mechanism 50 is actuated, i.e. they move. This step Ei3 consists, for example, of an instruction by the processor to the auxiliary motor 40, intended to trigger it, which drives the aforementioned three mechanisms when they are all coupled to a common pinion (or pulley) 40.1. The auxiliary motor 40 switches from the first position to the second position, so that the clamping mechanism 54, the coupling mechanism 52 and the holding mechanism 50 switch from their respective insertion positions to their respective clamping, coupling and holding positions. Preferably, the auxiliary motor 40 maintains the second position at the end of step Ei3, even if it is no longer powered.

[0150] Steps Ei1, Ei2 and Ei3 are in particular executed by the processor 45.1.

[0151] At the end of this initialization method Ei, the mixer 6 is ready to start working with the first and second capsules 3, 4, which are the subject of the mixing Er and recovery Em methods.

[0152] The mixing method Em comprises a first preparatory step Em1 ("first step of actuating the actuation system"), during which the connecting weld of the capsule located furthest from the heater element 46 is broken (second capsule in the figure) and this capsule is compressed so that its contents are partially sent towards the capsule closest to the heater element 46. According to the presented exemplary embodiment, the second actuating member 38 is actuated so as to break the connecting weld in the second capsule 4 (containing, for example, a fat phase composition). In this way, part of the contents of the second capsule 4 is sent at the side of the first capsule 3, in particular to the connecting passage 3.3 (since the connecting weld of the first capsule 3 has not yet been broken). The second actuating member 38 is preferably actuated along its actuating stroke C38. Due to the simplified design, there is not necessarily a partial stroke sensor for the second actuating member 38.

[0153] In the preparatory step Em2 ("second step of starting the actuation system" or "prestressing step"), the first actuating member 37 is actuated along a partial stroke that is much smaller than its actuation stroke C37, and holds its position so that the plane 3.7 is pressed against the diffusion plate 46.2, in order to prestress the first capsule 3 (containing, for example, an aqueous phase composition). This prestress makes it possible to promote heat exchange between the diffusion plate 46.2 and the first capsule 3 during the subsequent step Em3 ("heating step"). It should be noted that this pressing of the first capsule 3 against the diffusion plate 46.2 is achieved by actuating the first actuating member 37 over a partial stroke, without causing failure of the coupling weld of the first capsule 3 (which would result in the transfer of the composition from the first capsule 3 to the second capsule 4).

[0154] In the preparatory step Em3 ("heating step"), the heater element 46 is activated to generate the heat intended for the first capsule 3. Since the heater element 46 is arranged on the side of the plane 3.7 of the first capsule 3 and the prestressing step has allowed good thermal contact between the diffusion plate 46.2 and the first capsule 3, the heat provided by the heater element 46 is well distributed throughout the contents of the first capsule 3. Step Em3 is therefore activated without any movement of the actuating members 37, 38. During the preparatory step Em3, the temperature of the heater element 46 reaches a target temperature Tc comprised between 80°C and 90°C. The aim of this target temperature Tc is that the contents of the first capsule 3 also reach a target temperature Tc' comprised between 80°C and 90°C, preferably of the order of 85°C. In fact, it was found that the temperature of the contents of the first capsule 3 during this heating step Em3 substantially corresponded to the target temperature Tc of the heater element 46, albeit with a small time offset.

[0155] Next, in the kneading phase step Em3' ("mixing step"), the heater element 46 is deactivated and then the first actuating member 37 is started along its nominal stroke to break the joint weld of the first capsule 3. Cutting off the power supply to the heater element 46 before the actuation of the first actuating member 37 makes it possible to have all the power provided by the power supply available to supply the drive motor 39. Such a property is particularly advantageous when the mixer 6 is powered by a power transformer or a low-power battery 44. In fact, it prevents the power provided to the drive motor 39 from being insufficient to allow a failure of the joint weld of the first capsule 3 (which would then lead to a blockage of the device), this joint weld failure step requiring a high motor torque. When the first actuating member 37 reaches its end of the actuating stroke C37, the contents of the first capsule 3 are sent to the second capsule 4, and the two compositions can then freely circulate with each reciprocating movement of the actuating system 35 from the first or second capsule 3, 4 to the other second or first capsule 4, 3 via the connecting parts 3.2, 4.2, the connecting weld originally present in each of the first and second capsules 3, 4 being broken.

[0156] Then, steps Em4, Em5, Em6 are successive kneading steps with or without heating (this is called the kneading stage).

[0157] The kneading phase step Em4 ("kneading without heating") consists of starting the actuating members 37, 38 back and forth without activating the heater element 46, i.e. without heating. During this step, the first and second capsules 3, 4, respectively, are deformed at least once. According to one embodiment, step Em4 lasts for at least 1.4 seconds, preferably between 2 and 4 seconds. Such a kneading step without heating makes it possible to start the drive motor 39 at a constant speed, benefiting from the full power of the power supply.

[0158] Steps Em1, Em2 and Em3, Em3', Em4 alternate between starting the actuation system 35 and heating by the heater element 46. This specifically results in the power supply being dedicated either to the actuation system 35 or to the heater element 46. This exclusive alternation makes it possible to protect the battery 44 by distributing the time of high power. Indeed, the engagement during start-up generates a significant resistance torque, which imposes a significant motor torque, and a temperature rise, which also requires a significant power, at which time the battery 44 is highly loaded. This alternative solution also makes it possible to reduce the size of the components, which is a design constraint when making a portable, battery-powered mixer. On the other hand, when the temperature approaches the target temperature Tc' and the actuation system 35 is already operating, the load on the battery 44 is reduced, allowing a parallel supply to the heater element 46 and to the actuation system 35, which is the purpose of step Em5.

[0159] During the kneading phase step Em5 ("step of kneading with heating"), the actuation system 35 remains activated and the heater element 46 is reactivated to maintain the mixture of the composition at a temperature that is preferably the target temperature Tc'. As a result, the heater element is maintained at the target temperature Tc. This step Em5 lasts, for example, between 5 and 30 seconds, preferably between 7 and 15 seconds. The battery 44, although less loaded than for engagement at or for the temperature rise, may have a tendency to be rapidly discharged at this stage and is therefore limited in duration. However, this step Em5 is long enough for the first and second capsules 3, 4, respectively, to be deformed several times and for the emulsion obtained by mixing the compositions to be satisfactory.

[0160] Between steps Em4 and Em5, the actuation system 35 is not interrupted.

[0161] Then, the kneading phase step Em6 ("cooling step with kneading") is carried out. Alternatively, this step is carried out without kneading, but it is preferable to leave the actuation system 35 activated in order to improve or maintain the homogenization of the composition. During step Em6, the temperature of the cream is reduced to a recovery temperature Tr' comprised between 35°C and 48°C, preferably between 38°C and 42°C. In the case of the presented embodiment, the recovery temperature Tr' of the cream corresponds to a recovery temperature Tr of the heater element 46 comprised between 55°C and 60°C. This temperature deviation between the contents of the first and second capsules 3, 4 and the temperature of the heater element 46 during the cooling step is explained in particular by the fact that during kneading, the composition is present only part of the time in the first capsule 3 and therefore facing the diffuser plate 46.2, at the height of the diffuser plate 46.2 where the temperature measurement is carried out. The simplest cooling technique is to stop the supply to the heater element 46, allowing the cream to cool with room temperature air. The duration of step Em6 therefore effectively depends on the room temperature. In this respect, the temperature sensor is advantageously arranged in the mixer 6, more particularly in the receiving device 5. In order to limit the number of temperature sensors, it is the same sensor that measures the temperature of the heater element 46. As in the illustrated embodiment, the temperature sensor measures the temperature of the heater element 46, and the same sensor is reused, which means that the end of step Em6 is determined by the temperature measured by said sensor, i.e. the recovery temperature Tr' comprised between 55°C and 60°C. When the recovery temperature is reached, the actuation system 35 is switched off. The cooling step Em6 generally lasts at least 20 seconds, preferably 40 seconds. In one variant, step Em6 may also advantageously include a minimum kneading period, for example of the order of 40 seconds, making it possible to guarantee a good emulsion, followed by an additional kneading period that only occurs if the recovery temperature Tr' has not yet been reached. That is to say, kneading is still done for a certain time, even if the temperature is lower than the recovery temperature Tr'. It is noted that the mixer 6, according to an embodiment not shown, could include a cooling system to actively cool the cream and speed up the process.For example, a cooling system could be provided with a small fan, in addition to or without a cooling element, which forces air circulation within the mixer 6, thus providing forced convection cooling.

[0162] Once the mixing method Em is completed, the recovery method Er can be engaged, which will now be described.

[0163] Since the previous step takes some time (usually more than a minute), the user may not remain near the mixer 6 and perform his usual activities (breakfast, radio, television, buttering bread, dressing, ironing, etc.). It is therefore important that the mixer 6 is able to keep the cream ready to use for a given period of time.

[0164] For this purpose, in step Er1 ("transport for storage"), the actuation system 35 is activated once to transfer the cream to a capsule (i.e. here the first capsule 3) that is placed to the side of the heater element 46. This step is optional if step Em6 has already stopped in the correct configuration. In step Er2 ("prestress holding step"), the actuation system 35 is returned to the prestress position, where the first actuation member 37 prestresses the first capsule 3, pressing it against the spreader plate, and then, in step Er3 ("temperature maintenance step"), the heater element 46 is reactivated to maintain the cream at the recovery temperature Tr'. The prestress holding step Er2 allows a better heat transfer, as in step Em2. Preferably, the kneading or operation of the actuation system 35 is performed periodically during step Er3 to ensure a good emulsion, which may be partially deteriorated by the presence of hot spots on the spreader plate 46.2. In one variant, the recovery method may include, instead of step Er2, a step Er2' ("neutral position holding step"), in which the actuation system 35 is actuated and placed in a neutral position, i.e. without applying pressure to the first or second capsule 3, 4, in particular without applying pressure to the first capsule 3 relative to the heater element 46. Surprisingly, such a variant allows to maintain a better emulsion and avoids the need to resort to periodic kneading during the warming phase. Step Er3 is carried out for a given waiting time. This duration is less than 15 minutes, so as not to feed the heater element 46 for a long time, but more than 1 minute, preferably of the order of 5 minutes, so as to allow the user to have flexibility in his morning time management. In other words, this means that, after the end of the operation of the actuation system 35, the user has a time between 1 and 15 minutes, preferably of the order of 5 minutes (depending on the factory or user settings), to collect the cream at the right temperature.

[0165] When the user is ready to use the cream, he touches the touch screen or presses a button, which triggers step Er4 ("receiving a withdrawal instruction"), during which the mixer 6 receives a withdrawal instruction. Then, in step Er5 ("setting to neutral position"), the actuation system 35 is actuated and set to a neutral position. If the actuation system 35 is pre-stressed at the height of the first actuation member 37, the first actuation member 37 must complete its operation, which displaces the composition in the second capsule 4, after which the actuation system 35 stops in a neutral position, which corresponds to a position adapted to withdraw the receiving device 5. This position also corresponds to a starting position, adapted to accomplish the next production cycle implementing the method described above. In fact, the second actuation member 38 is then ready to compress the second capsule 4, during step Em1, as soon as the drive motor 39 is started. In the case of the variant in which the actuation system 35 was set in a neutral position during the temperature maintenance step Er2' of step Er3, it may be necessary that the actuation system 35 must perform a reciprocation so that it is in a neutral position adapted to accomplish the next production cycle implementing the above method, i.e. in a position in which the second actuation member 38 is ready to compress the second capsule 4 during step Em1. During this reciprocation of the actuation system 35, the cream present in the first capsule 3 is partially sent to the second capsule. Finally, in the last step Er6 ("unlocking step"), the mechanisms activated in step Ei3 are placed in the insertion position. This step Er6 also involves the start-up of the auxiliary motor 40.

[0166] The user then grasps the receiving device 5 and pulls it out of its receiving housing 32. He then presses on the working surfaces 8.1, 9.1 in order to rotate the wing members, expelling the cream present in the first and second capsules 3, 4 through the outlet passage 3.5 of the first capsule 3. Finally, it is sufficient to pull the first or second capsule 3, 4 out of the receiving device 5, leaving the latter ready for use again. In fact, no part of the mixer 6 (production device 2 or receiving device) is in contact with the composition.

[0167] Thus, the different steps for carrying out the above method, which may for example be carried out in succession, are: Ei1: Receiving a start command (performed by the mixer, more specifically, by the processor); Ei2: Arranging the actuation system (performed by the processor controlling the mixer, more specifically the drive motor); Ei3: Closing the clamping, holding and coupling mechanisms, preferably in parallel (performed by the mixer, more specifically by the processor controlling the auxiliary motor), Em1: the first step of initiating the actuation system to break the joint weld of one of the capsules (performed by the processor controlling the mixer and, more specifically, the drive motor); Em2: A second step of starting the actuation system to prestress the other capsules (performed by the processor controlling the mixer and more specifically the drive motor); Em3: Heating the prestressed capsule (performed by the mixer, more specifically by the processor controlling the heater element); Em3': A mixing step (performed by the processor controlling the mixer, more specifically the drive motor) by starting the actuation system in order to break the interlocking welds of the other capsules and allow the free circulation of the composition from one capsule to another; Em4: A step of kneading without heating to start the motor at a constant speed (performed by the mixer, more specifically, the processor controlling the drive motor); Em5: Heating and kneading to achieve an emulsion (performed by the processor controlling the mixer, more specifically the drive motor and heater elements); Em6: A step of cooling without heating (cooling) to a recovery temperature with kneading (performed by a mixer including a processor controlling a drive motor); Er1: an optional step of starting the actuation system and transferring for storage (performed by the processor controlling the mixer, more specifically the drive motor); Er2: Setting the actuation system to a prestressed position (performed by the mixer, more specifically by the processor); Er2': setting the actuation system in a neutral position (alternative to step Er2) (performed by the mixer, more specifically by the processor controlling the drive motor); Er3: Temperature maintenance step (performed by the mixer, more specifically the processor); Er4: Receiving a pull command (performed by the mixer, more specifically, by the processor); Er5: Setting the actuation system in a neutral position (performed by the processor controlling the mixer and more specifically the drive motor); Er6: Unlocking step (performed by the processor controlling the mixer and more specifically the auxiliary motor).
