Description

Technical Field

[0001] The present invention relates to a manufacturing device for manufacturing a composition, in particular a cosmetic composition, or more precisely to a manufacturing device for preparing a composition by mixing two preparations. Background Art

[0002] Document FR3026622 discloses a manufacturing device for manufacturing a composition, more specifically a cosmetic product, comprising:

[0003] a first capsule comprising a first compartment and a first connection portion, the first compartment comprising a predetermined amount of a first formulation;

[0004] a second capsule comprising a second compartment comprising a predetermined amount of a second agent and a second connection portion configured to connect to the first connection portion; and

[0005] A mixer is configured to receive the first and second capsules and mix the first and second preparations directly inside the first and second capsules to obtain a cosmetic product.

[0006] The mixer includes in particular:

[0007] a first pressing element comprising a first pressing surface configured to exert a pressure on the deformable first compartment of the first capsule, the pressure being perpendicular to a direction of movement of the first pressing element;

[0008] a second pressing element comprising a second pressing surface configured to exert a pressure on the deformable second compartment of the second capsule, the pressure being perpendicular to a movement direction of the second pressing element; and

[0009] A driving motor is mechanically connected to the first and second pressing elements and is configured to allow the first and second pressing elements to cyclically move between an inactive position and an active position.

[0010] This manufacturing device allows the manufacture of personalized beauty products by the end consumer using different capsules.

[0011] However, the structure of the manufacturing device described in document FR3026622 requires the provision of a large-sized drive motor in order to transmit a pressure to the deformable first and second compartments, which pressure is suitable for ensuring that the contents move from the first compartment toward the second compartment and conversely from the second compartment toward the first compartment, especially when the deformable first and second compartments or the connecting channel connecting the deformable first and second compartments are closed by a weak connection area.

[0012] The provision of a large-sized drive motor significantly increases the manufacturing cost of the manufacturing equipment as well as the volume and weight of the manufacturing equipment.

[0013] Furthermore, the mixing of capsules appears to be more complex than expected and both the materials and the way they are used need improvement. Summary of the invention

[0014] The present invention aims to overcome all or part of these disadvantages.

[0015] The technical problem underlying the present invention is therefore to provide a device for producing a composition which is simple, compact and easy to use and which at the same time has a simple and reduced-price structure.

[0016] In particular, certain designs in the form of mixers that can accommodate a receiving device for integrating capsules present additional problems of accessibility, especially when the capsules have different sizes. Furthermore, the overall dimensions of the device should be limited to the greatest extent possible.

[0017] In this aspect, the present invention provides a mixer configured to receive a receiving device to form a manufacturing device, the mixer comprising:

[0018] - a support member, the support member defining a receiving portion, the receiving portion comprising a first receiving portion and a second receiving portion, the first receiving portion being configured to receive a first deformable capsule, the second receiving portion being configured to receive a second deformable capsule, the first and second capsules being configured to be fluidically connected to each other and contain a first formulation and a second formulation, respectively;

[0019] - an actuation system, the actuation system being movable relative to the support member in the housing portion, the actuation system comprising:

[0020] a first actuation member positioned at one side of the accommodation portion and movable within the accommodation portion so as to transmit pressure to the first capsule according to a first actuation stroke;

[0021] a second actuation member, which is positioned on the other, preferably opposite, side of the housing and is movable within the housing in order to transmit pressure to the second capsule according to a second actuation stroke,

[0022] Wherein, the first actuation stroke has a different length from the second actuation stroke.

[0023] In one embodiment, the actuation system is movable in reciprocating rotation about a pivot axis.

[0024] In one embodiment, the pivot axis is offset relative to a longitudinal separation line of the receiving portions.

[0025] In one embodiment, the actuation system is driven to rotate by a cam, the cam is rotationally movable about a cam rotation axis orthogonal to the pivot axis, and the cam rotation axis does not intersect the pivot axis.

[0026] In one embodiment, the first receiving site comprises a first placement surface configured to receive a flat surface of the first capsule, and the second receiving site comprises a second placement surface configured to receive a flat surface of the second capsule, the two surfaces are parallel, and wherein a maximum distance from the first actuation member to the first support surface is different from a maximum distance from the second actuation member to the second support surface.

[0027] In one embodiment, the two actuation members are symmetrical to each other on either side of a symmetry plane, and wherein the symmetry plane is not equidistant from the two resting surfaces when the plane is parallel to the first and second resting surfaces.

[0028] In one embodiment, each actuation member comprises an actuation finger, the actuation finger of the first member being longer than the actuation finger of the second member.

[0029] In one embodiment, each actuation member comprises a spring adapted to be compressed when the actuation member reaches the end of its actuation stroke.

[0030] In one embodiment, the two springs have identical properties.

[0031] In one embodiment, the actuation system is driven to rotate by a cam, which can be rotated and moved around an axis orthogonal to the pivot axis, and a neutral position is defined for the actuation system, which is obtained for a position offset by a non-zero angle relative to the top dead center or the bottom dead center of the cam, so that one of the two actuation strokes is shorter than the other.

[0032] Preferably, the actuation stroke of the actuation member is defined between a neutral position of the actuation system and a maximum actuation position of the actuation member.

[0033] Preferably, the maximum position is a position in which the actuation member is in maximum compression on a support element arranged to exert a force on the respective capsule. BRIEF DESCRIPTION OF THE DRAWINGS

[0061] Figure 1A and Figure 1B A manufacturing device 2 according to a first embodiment of the present invention is shown, which is configured to manufacture a composition, which composition may be, for example, a beauty product, a hair care product, a medicinal product, a sterilization product, a maintenance product, a cleaning product or an agricultural product. When the composition to be manufactured is a beauty product, the beauty product may be, for example, a homogeneous emulsion, a homogeneous solution or a mixture of multiple soluble phases.

[0062] The manufacturing device 2 is intended for primarily personal use and for small dimensions: it allows the manufacturing of a single portion ready for use. Therefore, the dimensions of the manufacturing device should meet volume constraints in bathrooms, beauty salons, luggage (for transport), etc. Therefore, the manufacturing device 2 does not have a dimension greater than 40 cm.

[0063] The manufacturing device 2 includes a receiving mechanism configured to receive first and second capsules 3, 4, also referred to as tablets or packaging units, the first and second capsules comprising a predetermined amount of a first preparation and a predetermined amount of a second preparation, respectively, and a mixer 6 configured to mix the first and second preparations contained in the first and second capsules 3, 4 received in the manufacturing device 2 in order to obtain a cosmetic product.

[0064] The mixer 6 comprises a housing which is part of the receiving mechanism and is arranged to receive the first and second capsules 3 , 4 directly or through specific receiving means 5 .

[0065] In the preferred and especially in the attached Figure 1A , 1B, 7A, 8A, 8B, 8C, in all the figures, the mixer 6 comprises a housing 32 which can removably receive the receiving device 5. In this case, the housing 32 has a shape which is substantially complementary to that of the receiving device 5.

[0066] The mixer 6 also comprises an actuation system 35 configured to exert a force on the first and second capsules 3 , 4 , if necessary via the containment means 5 , so as to allow mixing and stirring of the composition to be manufactured.

[0067] The receiving device 5 is also called a shuttle (because it is used as a carrier for the first and second capsules 3, 4) and preferably has a relatively symmetrical shape, such as a parallelepipedal or an elliptical / oval shape. A longitudinal direction X may be defined for the receiving device, which corresponds to a direction along which the receiving device is inserted into the receiving portion 32. Thus, when the receiving device 5 is inserted into the mixer 6, the longitudinal direction X coincides with the insertion direction.

[0068] Advantageously, the mixer 6 is configured to mix the first and second formulations inside the containment device 5 and preferably inside the first and second capsules 3 , 4 , without any formulation coming into contact with the manufacturing device 2 .

[0069] As indicated further above, some of the embodiments presented here can be used in a production apparatus 2 without a receiving device 5 , ie wherein the first and second capsules 3 , 4 can be positioned directly in the mixer.

[0070] Advantageously, the first formulation is the first phase of the cosmetic product to be manufactured, such as the oil phase of the cosmetic product, and the second formulation is the second phase of the cosmetic product, such as the aqueous phase of the cosmetic product. For example, the oil phase may constitute the matrix of the cosmetic product to be manufactured, and the aqueous phase may include active ingredients and thus constitute the active complex of the cosmetic product to be manufactured.

[0071] capsule

[0072] Two capsules can be used in the present manufacturing device 2 , which is described in detail in the document filed under application number FR 1 755 744 and whose description is incorporated herein.

[0073] Capsules are therefore not an object of the present invention.For the purpose of the following description, the following points will be reviewed.

[0074] More specifically, if Figure 2A , 2B, 3A, 3B, 4A, 4B, the first and second capsules 3, 4 are different from each other and are configured to be fluidically connected to each other. In addition, each of the first and second capsules 3, 4 is advantageously disposable.

[0075] The first capsule 3 comprises a first deformable compartment 3.1 having a convex shape, a first connecting portion 3.2 and a first connecting channel 3.3, the first deformable compartment containing a first preparation, the first connecting channel being configured to fluidically connect the first deformable compartment 3.1 and the first connecting portion 3.2. Advantageously, the first connecting channel 3.3 is formed by a first connecting conduit. The first connecting portion 3.2 more specifically comprises a female connecting connector 3.4, for example of a cylindrical shape, which is fluidically connected to the first connecting channel 3.3. The first capsule 3 comprises a flat surface 3.7 through which the first connecting portion 3.2 passes.

[0076] The first capsule 3 further comprises an output channel 3.5, such as an output duct, which is fluidically connected to the first connection channel 3.3 and is equipped with an output hole 3.6. Advantageously, the output channel 3.5 is in the extension of the first connection channel 3.3 and extends substantially parallel to the first connection channel 3.3. In this case, the output channel 3.5 can be mounted indifferently on the first capsule 3 or on the second capsule 4. In fact, the output channel 3.5 is only required to work when the manufacturing device 2 is used.

[0077] The second capsule 4 comprises a second deformable compartment 4.1 having a convex shape, a second connecting portion 4.2 and a second connecting channel 4.3, the second deformable compartment containing a second preparation, the second connecting portion 4.2 being configured to be connected to the first connecting portion 3.2, the second connecting channel being configured to fluidically connect the second deformable compartment 4.1 and the second connecting portion 4.2. Advantageously, the second connecting channel 4.3 is formed by a second connecting conduit, and the second connecting portion 4.2 extends substantially vertically relative to the second connecting channel 4.3. The second connecting portion 4.2 more specifically comprises a male connecting connector 4.4, for example, of a cylindrical shape, which is fluidically connected to the second connecting channel 4.3 and is configured to receive the female connecting connector 3.4 in a sealed manner. The second capsule 4 comprises a flat surface 4.7, through which the second connecting portion 4.2 passes.

[0078] The first and second capsules 3, 4 and more specifically the first and second deformable compartments 3.1, 4.1 are each closed by a connecting solder which ensures the leaktightness of the first and second capsules 3, 4, these connecting solders being brittle as soon as pressure thresholds are reached. These pressure thresholds can be reached in the mixer 6. Again, these connecting solders are described in detail in the description of the document filed under application number FR1755744.

[0079] Each of the first and second capsules 3, 4 is configured as a whole or nearly a whole containing a mixture formed by a predetermined amount of the first agent and a predetermined amount of the second agent. To this end, the deformable compartment is flexible and a buffer area is provided. Again, this is precisely described in the description of the document filed under application number FR1755744.

[0080] Storage device

[0081] More specifically, if Figure 2A , 2B, 3A, 3B, 4A, 4B and 5, the receiving device 5 can occupy an open position and a closed position, in which the first and second capsules 3, 4 can be introduced into the receiving device 5, and in which the closed position the receiving device 5 can hold the first and second capsules 3, 4 in place.

[0082] The storage device 5 is more specifically a storage box 7 ( Figure 2A , 2B), the storage box is configured to at least partially store and accommodate the first and second capsules 3, 4. The storage device 5 particularly includes a first protective shell 8 and a second protective shell 9, which are arranged around a hinge axis 10 (or hinge) in a first position (see Figure 2A , 2B, 5) and the second position ( Figure 4A , 4B) are hingedly mounted relative to each other, the first position corresponds to the open position of the storage device 5, and the second position corresponds to the closed position of the storage device 5. The storage device 5 also includes a first support portion 11 and a second support portion 12 arranged in the storage box 7. The first and second support portions 11, 12 respectively include a first storage position 13 and a second storage position 14, the first storage position is configured to store the first capsule 3, and the second storage position is configured to store the second capsule 4. The first and second protective shells 8, 9 each include an opening 8.2, 9.2 for allowing access to the first or second storage position 13, 14. These openings 8.2, 9.2 define an insertion surface of the storage device 5. The storage device 5 includes a removal surface opposite to the insertion surface.

[0083] Advantageously, the first support 11 comprises a receiving pad 15 configured to receive a peripheral portion of the first capsule 3, and the second support 12 also comprises a receiving pad 15 configured to receive a peripheral portion of the second capsule 4. These receiving pads 15 partially define the first and second receiving locations 13,14.

[0084] The first supporting portion 11 comprises a first resting surface 11.1 which is configured to guide (have contact with) and receive the flat face 3.7 of the first capsule 3. The first resting surface 11.1 thus partially defines the first receiving location 13.

[0085] In the same way, the second supporting portion 12 comprises a second resting surface 12 . 1 configured to guide (have contact with) and receive the flat face 4 . 7 of the second capsule. The second resting surface 12 . 1 thus partially defines the second receiving location 14 .

[0086] When the first and second capsule 3, 4 are inserted, their respective flat faces 3.7, 4.7 are turned towards each other and have two resting surfaces 11.1, 12.1 between them.

[0087] In order to allow the passage of the first and second connecting portions 3.2, 4.2 of the first and second capsules 3, 4, the first and second seating surfaces 11.1, 12.1 each comprise a through opening 11.2, 12.2 in the form of a cutout and extending along the insertion axis X( Figure 1A ) opens outwards.

[0088] The storage device 5 further comprises a partition wall 22 which defines a partition surface ( Figure 3A , 3B). The partition wall 22 is located between the first and second storage locations 13, 14. The partition wall is also integral with the first support portion 11. The partition wall 22 comprises a through opening 22.2 to allow the first and second connection parts 3.2, 4.2 to be positioned in the storage device. The through opening 22.2 has the form of a through cut in thickness and is open to the outside.

[0089] The openings 11 . 2 , 22 . 2 , 12 . 2 thus form a space for receiving the connecting joints 3 . 4 , 4 . 4 of the first and second capsules 3 , 4 .

[0090] Furthermore, a first actuation surface 8 . 1 comprising the first shell 8 and the first support portion 11 and a second actuation surface 9 . 1 comprising the second shell 9 and the second support portion 12 are defined.

[0091] Each actuation surface 8.1, 9.1 participates in the transmission of the force received by the receiving means 5 towards the first and second capsules 3, 4. This will be explained in detail below.

[0092] Articulation

[0093] According to Figure 2A , 2B, 3A, 3B, 5, the first and second shells 8, 9 surround the hinge axis 10 and are in the storage position (see Figure 2A , 2B, 3A, 3B) and connection locations (see Figure 4A , 4B) are hinged relative to each other, in the storage position, the first and second shells 8, 9 are away from each other, and the first and second capsules 3, 4 can be stored in the first and second storage positions 13, 14 respectively, in the connection position, the first and second shells 8, 9 are close to each other, and the first and second capsules 3, 4 are pre-connected with each other. Pre-connection means that the male connection connector 4.4 of the second capsule 4 is partially inserted into the female connection connector 3.4 of the first capsule 3, and no sealing connection is established between the first and second capsules 3, 4.

[0094] When the first and second shells 8, 9 are in the storage position, the first and second shells 8, 9 may have, for example, an inclination angle greater than or equal to 7° and, for example, about 7°, and when the first and second shells 8, 9 are in the connection position, the first and second shells 8, 9 are substantially parallel to each other. More precisely, there are two main integral parts that are only hinged relative to each other: on the one hand, the first shell 8, the first support portion 11, the partition wall 22 and the second support portion 12; on the other hand, the second shell 9.

[0095] Advantageously, the first and second shells 8,9 (or actuation surfaces 8.1,9.1) are configured to insert the first connection part 3.2 into the second connection part 4.2 when the receiving device 5 is moved to the closed position. In fact, when the first and second shells 8,9 are in the closed position, the connection parts 3.2,4.2 partially nest with each other.

[0096] The first and second support portions 11, 12 are more particularly configured such that when the first and second shells 8, 9 are in the connected position, the first and second capsules 3, 4 extend substantially parallel to each other. Figure 4A 4B, when the first capsule is received in the receiving device 5 and the receiving device 5 is in the closed position, the first capsule 3 is configured to partially extend outside the receiving device 5. Advantageously, when the first capsule 3 is received in the receiving device 5 and the receiving device 5 is in the closed position, the output hole 3.6 is configured to extend outside the receiving device 5.

[0097] Heating elements

[0098] Manufacturing equipment 2 includes Figure 3A , the heating element 46 visible in 3B. In the embodiment depicted in the figures, the heating element 46 is part of the receiving device 5. However, in the absence of a receiving device 5, the heating element can be integrated with the mixer.

[0099] The heating element 46 is fixed to the partition wall 22. At the time of design, the heating element 46 has been selected to be on the first support portion 11 side, which means that the heating element 46 is installed on one side of the partition wall 22 on the first support portion 11 side.

[0100] The heating element 46 preferably comprises one or more heating resistors 46.1 and a diffusion plate 46.2. The heating element 46 thus has a flat shape in order to better diffuse the heat and, if possible, has a width of at least 500 mm. 2 and preferably about 800 mm 2 area.

[0101] However, since the first support portion 11 is located between the first capsule 3 and the heating element 46, a communication opening 46.3 is provided in the first support portion 11, which directly connects the flat surface 3.7 of the first capsule 3 with the heating element 46 (ie, separated only by air).

[0102] Electrical contact tracks for heating elements

[0103] The heating element 46 needs to be powered. Preferably, the receiving device 5 does not comprise its own battery and should be powered when the receiving device is inserted into the receiving portion 32.

[0104] Therefore, an electrical connection is provided between the container 5 and the mixer 6 .

[0105] The receiving device 5 comprises an insertion surface and a removal surface, the openings 8.2, 9.2 are located on the insertion surface, and the insertion surface is the surface that first enters the receiving portion 32, and the removal surface is opposite to the insertion surface and is the surface that is visible when the receiving device 5 is inserted into the receiving portion 32. The receiving device 5 also comprises a first actuation surface 8.1 and a second actuation surface 9.1 that are opposite.

[0106] Finally, the receiving device 5 comprises a first connection surface 23 and a second connection surface 24, which are preferably opposite. Figure 2A In the embodiments shown in FIGS. 2B, 3A, 3B, 4A, 4B, the connection surfaces 23 and 24 correspond to the side surfaces of the heating element 46 and are therefore different from the first and second actuation surfaces 8.1, 9.1 and the insertion / removal surface.

[0107] The connecting surfaces 23, 24 extend between the actuating surfaces 8.1, 9.1 of the receiving device 5. Preferably, the connecting surfaces 23, 24 connect the actuating surfaces 8.1, 9.1 of the receiving device 5, ie, they are adjacent.

[0108] The general shape of the receiving device 5 is chosen so that the connection surfaces 23, 24 are spaced further apart than the actuation surfaces 8.1, 9.1 (and than the insertion / removal surface). On the other hand, if a smallest parallelepiped is used in which the receiving device 5 is inserted, the surfaces contacting the connection surfaces 23, 24 are further apart than the surfaces contacting the actuation surfaces 8.1, 9.1 and closer than the surfaces contacting the insertion / removal surface. This is caused by the fact that the receiving device is wider than it is thick (and, moreover, taller than it is wide).

[0109] The first connection surface 23 comprises a first electrical contact track 23.1 for supplying power to the heating element 46, and the second connection surface 24 comprises a second electrical contact track 24.1 also for supplying power to the heating element 46 ( Figure 2A , 3A, 3B, 4A, 4B). The electrical contact tracks 23.1, 24.1 are therefore outside the receiving device 5 in order to make contact with the complementary tracks ( Figure 2A , 4A, 4B).

[0110] This configuration has several advantages: firstly, it ensures a simple and effective electrical connection. It also avoids the risk of short circuits. In fact, once liquid flows in the housing 32 (for example water from a shower or a sink or a simply ruptured capsule), it is impossible for the two electrical contact tracks 23.1, 24.1 to contact the same amount of liquid at the same time.

[0111] The first connection surface 23 includes the first and second shells 8 , 9 , the first support portion 11 and a portion of the partition wall 22 .

[0112] In particular, the first connection face 23 comprises a longitudinal groove 23.2 having a bottom 23.21 and two side walls 23.22, 23.23. The first electrical contact track 23.1 is preferably positioned on the side walls 23.22 of the longitudinal groove 23.2. Figure 3A 3B, the bottom 23.21 and the side wall 23.23 are realized by a part of the first support part 11. Suitable cutouts 8.5 are therefore provided in the first shell 8 to leave a position for the longitudinal groove 23.2. The opposite side wall 23.22 is realized by a part of the partition wall 22. The first electrical contact track 23.1 is therefore positioned on this side wall 23.22 (because the heating element 46 is mounted on the partition wall).

[0113] Likewise, a similar longitudinal groove 24.2 is provided on the second connection surface 24, which has a cutout 9.5 in the second shell 9 and has a bottom 24.21 and two opposite side walls 24.22, 24.23. Due to the non-centering of the groove, the cutout 9.5 in the second shell 9 is less obvious than the cutout 8.5 in the first shell 8.

[0114] The grooves 23.2, 24.2 are configured to engage on respective complementary guide rails 31.1, 31.2 (sliding connection) provided in the housing 32 and on the (preferably opposite) connection sides. Figure 1A , 7A). Thus, the grooves 23.2, 24.2 form a cutout extending over the entire height of the portion of the receiving device 5 in which the grooves are located, at least to the insertion height. The complementary guides 31.1, 31.2 contribute to defining the housing 32 and are positioned on opposite edges.

[0115] In particular Figure 4A In the embodiment shown in FIG. 4B , the electrical contact tracks 23 . 1 , 24 . 1 are not located in the same horizontal plane, but are offset.

[0116] The electrical contact tracks 23 . 1 , 24 . 1 may take various forms: electrical pins, metal sheets (as shown), etc. The electrical contact tracks 23 . 1 , 24 . 1 are preferably slightly deformable in order to ensure permanent contact when the receiving device 5 is placed in the housing 32 .

[0117] Therefore, it is noted that the longitudinal grooves 23.2, 24.2 are not centered relative to the first and second actuation surfaces 8.1, 9.1 (see in particular Figure 2A , 4A, 4B). In terms of design, this is caused by the grooves mainly formed in the first support portion 11 and the first protective shell 8.

[0118] The benefit of this asymmetry lies in the positioning function. In fact, it is impossible to place the receiving device 5 in the wrong orientation (rotated 180° around the longitudinal axis X) because the grooves 23.2, 24.2 cannot be inserted into the guides 31.1, 31.2 and the second shell 9 abuts against the guides 31.1, 31.2.

[0119] In order to have a positioning effect for vertical rotation (i.e. trying to put the removal face first instead of the insertion face), the longitudinal groove 23.2, 24.2 does not extend over the entire height of the part of the first or second shell 8, 9 in which it is located. Therefore, no special parts need to be provided, and the stop effect is simply obtained by the part of the first or second shell 8, 9 that is not penetrated by the cutting effect. On the other hand, when the receiving device 5 is in the wrong direction, the first or second shell 8, 9 prevents the insertion of the groove 23.2, 24.2 on the guide rail 31.1, 31.2.

[0120] In addition, the longitudinal grooves 23.2, 24.2 each include an end stop 23.3, 24.4 located on the side of the removal surface. These end stops 23.3, 24.4 have the function of insertion stops so as to define the maximum insertion position in the receiving portion 32.

[0121] In fact, there are two different types of stops, which are located approximately at the same place: at the ends of the longitudinal grooves 23.2, 24.2.

[0122] Electrical contact tracks for temperature sensors

[0123] Because of the heating element 46 for mainly heating the first capsule 3, the first support portion 11 is preferred over the second support portion 12 in order to support the walls 23.23, 24.23 of the recesses 23.2, 24.2.

[0124] In fact, a temperature sensor (not shown in the figures) is connected to the rear of the diffuser plate 46 . 2 in order to measure the temperature in the vicinity of the first housing location 13 and therefore of the first capsule 3 .

[0125] The temperature sensor is typically a CTN (negative temperature coefficient thermistor).

[0126] The temperature sensor should also be electrically connected to the mixer 6 (in particular ultimately to the processor in order to collect data) and to the battery 44 with which the mixer 6 is equipped in order to power the temperature sensor. For this purpose, a first complementary electrical contact track 46.51 is provided at the first contact surface 23. This first complementary electrical contact track 46.51 is different from the first electrical contact track 23.1. More precisely, the first complementary electrical contact track 46.41 is provided in the first recess 23.2, on the side wall 23.23, i.e. on the side wall formed by the first support 11.

[0127] Similarly, a second supplementary electrical contact track 46.52 is arranged in the second recess 24.2.

[0128] The two supplementary electrical contact tracks 46.51, 46.52 are also advantageously offset. In the specific example, the supplementary electrical contact track 46.51 and the electrical contact track 24.1 are at the same level, and the supplementary electrical contact track 46.52 and the electrical contact track 23.1 are at the same level.

[0129] Figure 2A , 3A, 3B, 4A, 4B, 5 show these tracks.

[0130] Positioning Department

[0131] The storage device 5 comprises a positioning portion 17, which is used to ensure that the first and second capsules 3, 4 are correctly positioned, that is, the "correct" capsule 3, 4 is placed in the "correct" storage position 13, 14 (in Figure 2A , 5 ). The positioning portion 17 is preferably located at the end of the through opening 11 . 2 , 12 . 2 in order to prevent an unwanted passage of the connection joint 3 . 2 , 4 . 2 .

[0132] The positioning portion 17 includes at least one door leaf 17.1, which opens toward the outside of the storage device 5 (preferably two door leaves on each side, as shown in the figure; preferably, the two door leaves 17.1 have a bar-style configuration, i.e., are hinged toward the outside of the storage device by hinges).

[0133] Specifically, the positioning portion 17 fulfills two different roles.

[0134] The door leaf 17.1 comprises an opening 17.2 having a shape complementary to the female connection joint 3.4 of the first capsule 3 so as to permit its insertion into the opening 8.2. Furthermore, the door leaf 17.1 comprises a stop 17.3 which contributes to defining the opening 17.2 so as to prevent the insertion of the second connection part 4.2, which is laterally longer than the first connection part 3.2, into the opening 8.2. Indeed, if an attempt is made to insert the second capsule 4 into the first housing position 13, the end of the second connection part 4.2, i.e. a portion of the male connection joint 4.4, abuts against the stop 17.3.

[0135] For entering the second storage position 14, when the storage device 5 is in the closed position, the positioning portion 17 blocks the second storage position: the through opening 12.2 is preferably also blocked by the stop 17.3. On the contrary, when the storage device 5 is in the open position, that is, when the second shell 9 is rotated on its hinge, the through opening 12.2 is released.

[0136] Finally, since the door leaf 17 . 1 is opened towards the outside, the first and second capsules 3 , 4 are not functionally blocked when they are taken out of the receiving device 5 (both at the same time, since they are fixed together).

[0137] Depending on the design of the relative movement of the parts, the positioning part 17 can be fixed to the first support part 11 or to the second support part 12 (as shown in the drawings): if the second support part 12 is fixed to the second shell 9 (and is therefore rotationally movable relative to the first support part 11), then the positioning part is preferably fixed to the first support part 11. In other words, it is indistinguishable.

[0138] The restoring spring 17 . 4 keeps the positioning portion 17 in the default position, ie the closed position.

[0139] Pressing element - blade

[0140] Especially Figure 2B As shown in Figures 3A, 3B, and 5, the storage device 5 also includes a first pressing element 19 and a second pressing element 21, the first pressing element 19 being configured to enter the interior of the second storage position 14, i.e., for applying pressure on the first capsule 3 and more specifically on the first deformable compartment 3.1, and the second pressing element 21 being configured to enter the interior of the first storage position 13, i.e., for applying pressure on the second capsule 4 and more specifically on the second deformable compartment 4.1.

[0141] The first pressing element 19 (or the second pressing element 21) is preferably mounted on the first supporting portion 11 (or the second supporting portion 12) and is movable between an inactive position, i.e., an unfolded position, and an active position, i.e., a folded position, in which the first or second storage position 13, 14 is easily accessible to the first or second capsule 3, 4 (see Figure 2B , 3A, 3B), in this effective position, the first pressing element 19 (or the second pressing element 21) enters the interior of the first storage position 13 (or the second storage position 14), that is, the first pressing element (or the second pressing element) can exert pressure on the first deformable compartment 3.1 of the first capsule 3 (or the second deformable compartment 4.1 of the second capsule 4).

[0142] The first pressing element 19 (or the second pressing element 21) is advantageously mounted so as to be rotatable around a hinge 19.1 (or hinge 21.1). The hinge 19.1 (or hinge 21.1) is located opposite the opening 8.2 (or opening 8.1) of the first shell 8 (or second shell 9). The hinges 19.1, 21.1 are therefore both located near the removal surface of the storage device 5.

[0143] The pressing elements 19, 21 each have a flat inner face 19.2, 21.2 so as to form a blade that is movable in rotation. Each flat inner face 19.2, 21.2 cooperates with its first or second capsule 3, 4, respectively. With the pressing on the pressing element, the space between the blade and the resting surface 11.1, 12.1 gradually and continuously decreases. When the first or second capsule 3, 4 is installed, the output hole 3.6 and the connection part 3.2, 4.2 are located on opposite sides of the hinge 10: this allows to effectively expel the cream of the first or second capsule 3, 4, while avoiding any undesirable retention area inside the first or second capsule.

[0144] In order to keep the pressing element 19, 21 in the default open position (ie when the receiving device 5 is not driven or when the second shell 9 is in the pivoted position), a restoring mechanism 21.3, such as a spring, is arranged to abut against the first or second shell 8, 9 ( Figure 5 ). The restoring mechanism 21.3 may tend to push the blade slightly extended on the other side of the hinge 21.1.

[0145] In use, as will be described later, the two pressing elements 19, 21 are driven in sequence so as to allow the cream to be stirred. Thus, the cream is transferred from a first or second capsule 3, 4 to another second or first capsule 4, 3.

[0146] Preferably, to optimize the operation of the blades, the hinge 19.1 (or hinge 21.1) defines an axis of rotation contained in the plane of the resting surface 11.1 (or resting surface 12.1) and perpendicular to the longitudinal axis of the receiving device 5. In the absence of a capsule, the inner face 19.2, 21.2 can rest against the resting surface 11.1, 12.1.

[0147] Likewise, the hinge 19 . 1 , 21 . 1 is preferably located exactly at the end of the first or second storage position 13 , 14 .

[0148] In order to move the pressing element 19, 21, the first and second shells 8, 9 preferably comprise, opposite the end of the blade (in order to exploit the lever effect and minimize the forces to be applied), each a pressing point 8.3, 9.3, configured to receive an external force, as will be described in more detail later. The pressing point 8.3, 9.3 is fixed to a flexible area 8.4, 9.4, which is deformable (made of an elastomer or the like). The flexible area 8.4, 9.4 itself is fixed to the remaining part of the first or second shell 8, 9, which is made of a more rigid plastic.

[0149] The pressure points 8.3, 9.3 are realized from a rigid material, typically plastic.

[0150] Alternatively (not shown), the first and second shells 8 , 9 have two holes, preferably opposite the ends of the blades, so as to allow free access to the pressing elements 19 , 21 .

[0151] The user can grasp the receiving device 5 with his hand and simultaneously press the pressure points 8.4, 9.4, for example by the thumb and the index / middle finger. The simultaneous pressure allows the cream of the first and second capsules 3, 4 to be guided towards the output opening 3.6.

[0152] In another embodiment not shown, the receiving device 5 is integrated with the mixer 6 , and the blades can be directly integrated into the mixer 6 .

[0153] Keep stop

[0154] In order to prevent the receiving device 5 from being removed from the receiving portion 32 during the stirring process, a holding mechanism 50, which will be described in detail later, is provided in the manufacturing device 2. In order to provide a support point for the holding mechanism 50 on the receiving device 5, a holding stop 9.6 is provided on one of the first or second shells 8, 9 (in Figure 2A , 2B, 3A, 3B, 4B, 5 are on the second shell 9). The retaining stop 9.6 corresponds mainly to a radially extending protrusion, i.e. a protrusion extending in a plane perpendicular to the longitudinal direction X. The retaining stop can be located at any position along the height of the receiving device 5. In the embodiment shown, the retaining stop 9.6 is arranged in the vicinity of the insertion surface.

[0155] For example, for ergonomic reasons, a further stop may be provided on the other shell.

[0156] Grip handle

[0157] In order to allow the user to hold the storage device 5 when the storage device 5 is inserted into the receiving portion 32, a gripping handle 8.7, 9.7 is provided on each of the first and second protective shells 8, 9 (particularly visible in Figures 1, 2B, 4A, 4B). These gripping handles 8.7, 9.7 are located at the removal surface, which is the surface that can be touched when the storage device 5 is placed.

[0158] The gripping handles 8.7, 9.7 can simply consist of radially extending projections, ie projections extending in a plane perpendicular to the longitudinal direction X, and are long enough to allow a part of the user's knuckle to lift over them.

[0159] Connect Button

[0160] As indicated above, the actuation surfaces 8.1, 9.1 and more particularly the first and second protective shells 8, 9 each comprise a pressure point 8.3, 9.4 in order to transmit a force towards the inner pressure element 19, 21. These pressure points 8.3, 9.4 are formed in the flexible areas 8.4, 9.4.

[0161] When the receiving device 5 is moved to the closed position, the connection joints 3.4, 4.4 are opposite to each other and partially nested. In order to establish a sealed and reliable fluid connection between the first and second capsules 3, 4, a connection mechanism 52 is provided in the manufacturing device 2. The connection mechanism 52 applies a force toward the receiving device 5. The connection mechanism 52 simultaneously allows the establishment of a fluid connection between the first and second capsules 3, 4 under the action of the force applied by the connection mechanism 52, and also allows avoiding any undesirable disconnection of the first and second capsules 3, 4 under the action of the pressure generated by the agitation of the first and second capsules 3, 4. It will be described later.

[0162] One (or even both) of the first or second protective shells 8, 9 comprises a connection button 9.8, which moves toward the second storage position 14 ( Figure 2A , 2B, 3A, 3B, 4A, 4B, 5). More precisely, the connection button moves towards the area close to the opening 9.2, because the connection button 9.8 is used to press the second capsule 4 near the connection part 4.2. For this purpose, the connection button 9.8 is fixed to the flexible area, which can be the flexible area 9.4 of the pressing point 9.3. It should be noted here that the connection button 9.8 is different from the pressing point 9.3.

[0163] The connection button 9.8 is preferably rigid in order to better transmit the force of the connection mechanism 52 to the first and second capsules 3, 4, so that the first and second capsules are kept connected.

[0164] Mixer

[0165] More specifically, if Figure 6 , 7A, 7B, 8A, 8B, 8C, 9, 10A, 11A, 11B, 11C, the mixer 6 includes a support portion 31 and a receiving portion 32, the receiving portion is at least partially defined by the support portion 31 and is configured to at least partially receive the receiving device 5. Figure 1A, 1B, the mixer 6 and the receiving device 5 are configured so that when the receiving device 5 is received in the receiving portion 32, the receiving device 5 at least partially extends outside the mixer 6. The support portion 31 serves as a base, i.e., when the mixer 6 is placed on a support (table, work plane...), the support portion defines the entirety of the fixing element, whether the mixer is used or not. The support portion 31 of the mixer 6 also includes a housing 33 and an insertion opening 34 leading to the receiving portion 32, and the receiving device 5 is configured to be inserted into the receiving portion 32 through the insertion opening 34. Advantageously, the insertion opening 34 is arranged in a central portion of the upper surface of the base 33 and is configured to be oriented upward when the mixer 6 is placed on a horizontal support surface (table, work plane...).

[0166] The base 33 also serves as an outer shell, which has a desired design for the mixer. The base 33 may include a lower base and an upper base.

[0167] Actuation system

[0168] The mixer 6 further comprises an actuation system 35 which is pivotally mounted on the support 31 about a substantially vertical pivot axis 36 when the mixer 6 is arranged on a horizontal support surface (table, work plane . . . ). Figure 6 , 8A, 8B, 8C, 9, 10A).

[0169] Preferably, the actuation system 35 performs a reciprocating movement about the pivot axis 36 along a maximum angular travel of 45°. The movement thus consists of a maximum rotation of +45° then -45°, etc. The movement of the actuation system is carried out along a nominal travel C35 (not shown in the figures) which is combined with the maximum angular travel in the case of a rotation about the pivot axis 36. The nominal travel C35 of the actuation system 35 is defined as the travel between the two extreme positions of the actuation system 35. An intermediate position of the actuation system 35 is defined between these two extreme positions, the intermediate position of the actuation system 35 corresponding to an insertion position in which the receiving device 5 can be positioned inside the housing 32 of the mixer 6 without being disturbed by the actuation system 35.

[0170] The mixer 6 further comprises a drive motor 39 mounted on the support 31. The drive motor 39 is configured to pivot the actuation system 35 about the pivot axis 36 and within a predetermined angular range. Preferably, the drive motor 39 rotates in only a single direction.

[0171] The actuation system 35 includes a first actuation member 37 and a second actuation member 38, wherein the first actuation member may include a first actuation finger 37.1, which is configured to transfer pressure to the first capsule 3, and the second actuation member may include a second actuation finger 38.1, which is opposite to the first actuation member 37 and is configured to transfer pressure to the second capsule 4.

[0172] When the receiving device 5 is received in the mixer 6 and more precisely in the housing 32 , the first and second actuating members 37 , 38 are configured to be arranged on both sides of the housing 32 and thus on both sides of the receiving device 5 .

[0173] The actuating members 37, 38 have at least one position in which they are at least partially inside the housing 32. In an intermediate position of the actuating system 35, the actuating members 37, 38 are arranged relative to the housing 32 so as to allow the receiving device 5 to be positioned inside the housing 32 of the mixer 6; this is the insertion position.

[0174] The first and second actuating members 37, 38 are more specifically configured to exert pressure on the first and second pressing elements 19, 21, respectively and alternately, so as to transmit pressure to the first and second compartments 3.1, 4.1, respectively and alternately. 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 cooperate with the pressing elements 19, 21.

[0175] An actuation stroke C37 for the first actuation member 37 and an actuation stroke C38 for the second actuation member 38 are defined.

[0176] The actuation stroke C37 is defined as the stroke of the first actuation member 37 between the middle position of the actuation system 35 and the maximum actuation position of the first actuation member 37 , in which the first actuation member 37 maximally presses the first pressing element 19 .

[0177] Conversely, the actuation stroke C38 is defined as the stroke of the second actuation member 38 between the middle position of the actuation system 35 and the maximum actuation position of the second actuation member 38 , in which the second actuation member 38 maximally presses the second pressing element 21 .

[0178] Preferably, the movement of the actuation system 35 can be tracked by means of different sensors, in particular Hall effect sensors. More precisely, each of the first actuation member 37 and the second actuation member 38 can comprise a magnet for interacting with a fixed Hall effect sensor. Advantageously, the Hall effect sensor can be arranged directly on the control unit 45 to be described later, such as Fig.12Therefore, for the control unit 45, the movement of the actuation system 35 can be tracked, and the movement of each of the first and second actuation members 37, 38 can also be tracked. For the control unit 45, it is also conceivable to accurately know the position of each of the first and second actuation members in their respective actuation strokes C37, C38, for example, by providing a plurality of Hall effect sensors.

[0179] According to the embodiment shown in FIGS. 1 to 12 , the first and second actuating members 37 , 38 extend substantially in the same plane of extension and converge opposite the pivot axis 36 .

[0180] like Figure 6 , 8A, 8B, 8C, 9, the actuation system 35 has a generally annular shape defining an opening around the housing 32. In an embodiment, the actuation system 35 is mainly formed by a single part, which includes an opening for receiving a shaft defining the pivot axis 36.

[0181] The first and second actuating members 37, 38 are each arranged on opposite sides of the actuating system 35. Thus, there is an actuating system 35 extending on two faces two by two opposite each other: the actuating members 37, 38, the opening for the pivot shaft 36 and the drive mechanism with the groove to be described later.

[0182] The actuating members 37, 38 may each comprise a drive support 37.3, 38.3 which is joined on one side at the pivot axis 36. On the other side, a connection 36.1 is defined which connects the two drive supports 37.3, 38.3. The connection 36.1 may be fixed to the drive supports 37.3, 38.3 or be from the same material.

[0183] Preferably, the two actuating members 37, 38 rotate about the same pivot axis 36. In this case, the two drive supports 37.3, 38.3 are preferably rotationally connected in one piece.

[0184] However, a pivot axis may be provided for each actuating member 37 , 38 ; however some simple adaptation should be provided.

[0185] Alternatively, in an embodiment not shown, the actuating member is movable in translation.

[0186] spring

[0187] The actuation system 35 moves along a nominal travel C35 in order to exert a force on the receiving device 5 .

[0188] However, play in the transmission chain related to manufacturing tolerances can disrupt the transmission of force by varying the position of the actuation system 35. Thus, at the end of the stroke, a few microns may be missing or, conversely, a few microns may be more. This can lead to insufficient compression of the manufacturing device 2 or, conversely, damage to the manufacturing device 2.

[0189] To overcome this problem, the actuation system 35 may include springs 37.4, 38.4 (particularly visible in Figures 8A, 8B, 8C). Specifically, the springs 37.4, 38.4 are configured to compress when the actuation system 35 reaches near the end of its rated travel C35 and the actuation fingers 37.1, 38.1 abut against the flat faces 3.7, 4.7 of the capsule. The springs 37.4, 38.4 thus generate a force tending to separate the actuation members 37, 38 of the receiving device 5.

[0190] More precisely, each actuating member 37 , 38 comprises a spring 37 . 4 , 38 . 4 .

[0191] The springs 37.4, 38.4 may be located at different positions. In an embodiment not shown, the springs 37.4, 38.4 are located at the "free" ends of the fingers 37.1, 38.1.

[0192] In another embodiment, the spring 37.4, 38.4 is mounted between the finger 37.1, 38.1 and the drive support 37.3, 38.3, preferably because the spring is covered. Thus, the user cannot touch it because the spring is behind the base.

[0193] In order to place the spring in this position, for each actuating member 37, 38, an arm 37.2, 38.2 is simply provided which is movably mounted relative to the drive support 37.3, 38.3. The finger 37.1, 38.1 is thus mounted integrally with the arm 37.2, 38.2.

[0194] In particular Fig. 8A In the embodiments shown in FIGS. 8B, 8C and 9, the arms 37.2 and 38.2 are rotatable relative to the drive supports 37.3 and 38.3 via hinges 37.5 and 38.5. The springs 37.4 and 38.4 are positioned between the arms 37.2 and 38.2 and the drive supports 37.3 and 38.3.

[0195] The springs 37.4, 38.4 therefore work in compression, meaning that the empty or unstressed position of the springs is not compressed. The springs are compressed in the translational or rotational direction of the actuating members 37, 38.

[0196] The springs 37.4, 38.4 can be spiral, sheet-type springs, or even comprise elastic materials or elastic assemblies (elastomers, bubbles, etc.).

[0197] Rotary drive

[0198] according to Figure 6 , 8A, 8B, 8C, 9, the mixer 6 further comprises a cam 41 in the form of a drive wheel or arm, which is rotationally connected to the output shaft 39.1 of the drive motor 39 and is configured to be rotationally driven around the rotation axis 41.1 of the cam. The cam 41 is mounted on the support 31. In order to allow a reciprocating motion with a large lever arm, preferably, the pivot shaft 36 and the cam 41 are on both sides of the housing 32.

[0199] The cam 41 is equipped with a drive finger 42 which is eccentric with respect to the axis of rotation 41 . 1 of the cam.

[0200] Cam 41 is typically driven by drive motor 39 via one or more belts. In this case, starting from drive motor 39 and output shaft 39.1 with pulley mounted, the transmission chain is as follows: belt 39.2, pulley 39.3 connected by shaft to pulley 39.4, belt 39.5, cam 41.

[0201] The drive finger 42 is received in a drive groove 43 provided on the actuation system 35. Specifically, the drive groove 43 is configured in the connection portion 36.1. The drive groove 43 is elongated and extends along an extension direction substantially parallel to the pivot axis 36. This configuration of the mixer 6 allows obtaining a reciprocating motion of the actuation system 35 while causing the drive motor 39 to always rotate in the same rotation direction, so that there is no need to use an expensive control system for the drive motor 39.

[0202] The driving groove 43 extends along its depth toward the pivot axis 36 .

[0203] The connection between the drive groove 43 and the drive finger 42 will now be described. The alignment of the drive groove 43 and the drive finger 42 is variable in view of the rotation of the actuation system 35, which means that a simple adjustment will jam the system. On the contrary, the presence of a gap that causes misalignment generates noise and gives a delay time to each end of stroke.

[0204] In order to solve this problem, a ball and socket connection is provided between the drive finger 42 and the drive groove 43, which allows the above-mentioned misalignment to occur.

[0205] In particular, a ball 42.1 is mounted on the drive finger 42, which ball is accommodated in a ring 43.1. The connection between the ball 42.1 and the ring 43.1 is a ball-and-socket joint connection. The ring 43.1 itself is housed in the drive groove 43, in which the ring is mounted so as to be movable in translation 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 movable in translation along the drive finger 42. The arrangement of these different connections can be different, meaning that the ring can also be movable in translation along the depth of the groove and the ball is thus fixed to the drive finger.

[0206] Thus, the complete connection between the drive finger 42 and the actuation system 35 comprises, in sequence, a guide rail, a ball joint, a guide rail perpendicular to another guide rail. Thus, in the kinematic torque, it is noted that the force is transmitted only on one of the six torque components, namely the component that translates tangentially to the rotational movement of the actuation system 35, i.e. the component that allows the rotation of the actuation system 35. The kinematic equivalent is a spherical-surface connection (also called a point connection).

[0207] In order that the connection is not unnecessarily complicated, the rotation axis 41 . 1 of the cam and the pivot axis 36 are preferably orthogonal. This allows having a drive finger 42 which performs a circular movement in a plane parallel to the pivot axis 36 .

[0208] The movement of some arrangements of the connection can be easily realized by means of plastic slides / plastic, which wear slowly enough to ensure a satisfactory lifespan.

[0209] According to a variant embodiment of the present invention, the mixer 6 can be configured so that the rotation of the drive motor 39 in a first rotation direction drives the actuating part 35 to pivot in a first pivot direction, and the rotation of the drive motor 39 in a second rotation direction opposite to the first rotation direction drives the actuating part 35 to pivot in a second pivot direction opposite to the first pivot direction.

[0210] Eccentricity of the pivot axis

[0211] The actuation members 37 , 38 each move along an actuation stroke C37 , C38 .

[0212] However, in the embodiment shown in the figures, one of the two actuation members 37, 38 has an actuation stroke C37, C38 whose length is strictly greater than that of the other actuation member. This difference in actuation strokes C37, C38 allows better mechanical and electrical management of the forces to be provided in order to deform the first capsule 3 relative to the second capsule 4. In fact, as Figure 2BAs shown, the first capsule 3 has a greater thickness than the second capsule 4 , which means that more space is needed on the side of the thickest capsule and the pressing element 19 will come into contact faster and work faster than the pressing element 21 .

[0213] In order to achieve this difference in stroke, several solutions are conceivable. One solution consists in having a drive groove 43 which is not centered in the connecting part 36.1.

[0214] especially Fig. 8A , 8B, 8C, 9, another solution is to eccentric the pivot axis 36. On the other hand, the rotation axis 41.1 of the cam does not intersect the pivot axis 36. When the cam 41 moves a complete circle, this leads to a difference in the stroke between the two actuating members 37, 38. A distance between the rotation axis 41.1 of the cam 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 sufficient and does not affect the overall symmetrical appearance too much. In absolute values, a distance between 1 mm and 2 mm is suitable.

[0215] The eccentricity can also be defined by means of the axis of rotation of the housing 32 relative to the cam 41 : the end positions of the actuation system 35 are therefore not centered around the housing 32 .

[0216] The eccentricity may also be defined relative to the first and second seating surfaces 11.1, 12.1 or relative to the position of the first and second capsules 3, 4 in the housing 32: by means of the flat surfaces 3.7, 4.7 which thus define an imaginary surface in the housing 32. The maximum distance of the first actuation member 37 to the surface of the flat surface 3.7 is greater than the maximum distance of the second actuation member 38 relative to the flat surface 4.7.

[0217] To this end, in a variant, the pivot axis 36 is contained in a plane equidistant from the two rest surfaces 11 . 1 , 12 . 1 .

[0218] Under the effect of the eccentricity, the first actuation finger 37.1 is advantageously longer than the second actuation finger 38.1. This is caused in particular by the fact that, due to the eccentricity, the end position of the actuation fingers 37.1, 38.1 is compensated. More precisely, the actuation finger 37.1, 38.1 that works on the thicker first or second capsule 3, 4 has a greater length than the other actuation finger 37.1, 38.1.

[0219] Fig. 8AAnother solution shown aims at not defining an intermediate position of the actuation system 35 at the high or low dead point of the cam 41. In fact, the distribution of the actuation strokes C37, C38 is staggered by choosing the intermediate position of the actuation system 35 at a non-zero angle Ag (typically Ag is between 5° and 30°) relative to the 12 o'clock direction (when the mixer 6 is placed on a horizontal support). Moreover, it should be noted that another intermediate position is thus obtained for an angle Ag' corresponding to Ag'=180°-Ag.

[0220] In fact, the actuation strokes C37, C38 correspond at the cam 41 to a rotation from said angle Ag to the nearest 90° (i.e. at 3 o'clock or 9 o'clock, when the mixer 6 is placed on a horizontal support), and then to a rotation from said angle Ag' to 270°. Since Ag and Ag' are not at 0° and 180° (12 o'clock and 6 o'clock), it is immediately noted that the strokes C37 and C38 are not equal. With respect to a complete rotation of the cam 41, a first actuation stroke C37 is thus passed in the first direction, then a first actuation stroke C37 is passed in the second direction, then a second actuation stroke C38 is passed in the first direction, then a second actuation stroke C38 is passed in the second direction, i.e. twice the nominal stroke C35.

[0221] Contact rails for mixers

[0222] As mentioned above, the mixer 6 itself also comprises 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 the complementary electrical contact tracks 46.51, 46.52 of the longitudinal grooves 23.2, 24.2.

[0223] These electrical contact rails are mounted on the guide rails 31.1, 31.2 ( Figure 1A , 7A), the guide rails 31.1, 31.2 are integral with the support part 31 and are mounted on the two connecting sides of the receiving part 32. The position of the electrical contact rails 31.11, 31.12 (and 31.51, 31.52) on the guide rails 31.1, 31.2 is complementary to the position of the electrical contact rails 23.1, 24.1 (and 46.5, 46.52) of the connecting faces 23, 24 of the receiving device 5. The guide rails 31.1, 31.2 contribute to defining the receiving part 32. The guide rails are, for example, located on the edge and are preferably fixed to the support part 31 over their entire length.

[0224] The location of the electrical contact tracks 31.51, 46.51 and 31.52, 46.52 on two opposing and mutually spaced guide rails 31.1, 31.2 has the advantage of limiting the risk of short circuits as soon as liquid flows by gravity onto one of the guide rails 31.1, 31.2.

[0225] Blocking mechanism, connecting mechanism, taking-out mechanism

[0226] The mixer 6 further includes a holding mechanism 50, a connecting mechanism 52 and a clamping mechanism 54 ( Fig. 10A , 10B, 10C, 10D, 10E, 10F, 11A, 11B, 11C).

[0227] Each of these mechanisms has its own and independent function. However, these mechanisms can advantageously be driven simultaneously by the same auxiliary motor 40.

[0228] The function of the holding mechanism 50 is to prevent the storage device 5 from being taken out during stirring.

[0229] The holding mechanism 50 is movably mounted between an insertion position and a holding position relative to the support 31. In the insertion position, the holding mechanism 50 allows the insertion and removal of the receiving device 5 relative to the mixer 6. In the holding position, the holding mechanism 50 prevents the removal of the receiving device 5 (and thus the insertion of the receiving device).

[0230] The retaining mechanism 50 comprises a mobile element 50.1 movable between the two positions mentioned above, which in the retaining position extends in the housing 32. In particular, in the retaining position, the mobile element 50.1 cooperates with the retaining stop 9.6 so as to prevent the translational movement of the receiving device 5 intended to be removed from the mixer 6 (in fact, in the case of removal, the retaining stop 9.6 is stuck against the mobile element 50.1). To this end, when the receiving device 5 is placed in the mixer, the mobile element 50.1 and the retaining stop 9.6 are arranged to be located near the retaining position, preferably less than 2 mm.

[0231] exist Fig. 10A , 10B, 10C, the movable element 50.1 is a wheel, i.e. a retaining wheel, which moves about a wheel rotation axis 50.2. The wheel 50.1 has at least two different radii, a smaller radius being configured not to extend into the receiving portion 32 in the insertion position, and a larger radius being configured to extend in the receiving portion 32 in the retaining position so as to contact against the retaining stop 9.6 in the case of removal.

[0232] The wheel 50.1 is preferably circular with a flat portion which allows for insertion into position.

[0233] The wheel 50.1 is mounted on a shaft extending along the wheel rotation axis 50.2. The shaft comprises a gear 51 or pulley connected to at least one further gear or further pulley 51.1.

[0234] Alternatively, the movable element 50 . 1 is movable in translation by means of a gear 51 , for example by means of a rack and pinion system.

[0235] The function of the connection mechanism 52 is to establish a sealed connection between the first and second capsules 3, 4 by pressing on the connection button 9.8 of the second protective shell 9 and to ensure that the first and second capsules are well kept nested by their connection joints 3.4, 4.4.

[0236] The connection mechanism 52 is movably mounted between an insertion position and a connection position relative to the support 31. In the insertion position, the connection mechanism 52 allows insertion and removal of the receiving device 5. In the connection position, the connection mechanism 52 locks the first and second capsules 3,4.

[0237] The connection mechanism 52 comprises a connection element 52.1 movable between the two positions, which in the connection position extends in the housing 32. Specifically, in the connection position, the connection element 52.1 cooperates with a connection button 9.8, which moves inside the second storage position 14. For this purpose, when the storage device 5 is installed in the mixer 6, the connection element 52.1 and the connection button 9.8 are opposite to each other.

[0238] exist Fig. 10A , 10B, 10C, the connecting element 52.1 is a wheel, i.e., a connecting wheel, which moves around a wheel rotation axis 52.2, which preferably coincides with the wheel rotation axis 50.2. The wheel 52.1 has at least two different radii, a smaller radius being configured not to extend into the receiving portion 32 in the inserted position, and a larger radius being configured to extend in the receiving portion 32 in the connected position so as to contact and press the connection button 9.8.

[0239] The wheel 52 . 1 preferably has an oval shape in the plane.

[0240] The wheel 52.1 is mounted on a shaft extending along the wheel rotation axis 52.2. The shaft comprises a gear or pulley connected to at least one further gear or further pulley 51.1. The shaft and gear are preferably identical to the shaft and gear 51. Thus a first sub-integral of rotational connection is obtained.

[0241] Alternatively, the connecting element 52 . 1 is movable in translation by means of the gear wheel 51 , for example by means of a rack and pinion system.

[0242] The connection mechanism 52 is different from the actuation system 35. This is caused by the different position (eg different height) in the mixer 6. Similarly, the receiving device 5 comprises a different pressing point 8.3, 9.3 than the connection button 9.8.

[0243] The function of the clamping mechanism 54 is to clamp the outlet channel 3.5 of the first capsule 3 while the mixing process is ongoing. In fact, the pressure inside the first or second capsule 3, 4 can cause an undesired outlet of the cream. In this case, the cream spreads in the mixer 6, which is to be prohibited. This is Fig.11A , as shown in 11B, 11C.

[0244] The clamping mechanism 54 is movable between an insertion position and a clamping position relative to the support 31. In the insertion position, the clamping mechanism 54 allows insertion and removal of the receiving device 5 carrying the first capsule 3. In the clamping position, the clamping mechanism 54 clamps the output channel 3.5.

[0245] The clamping mechanism 54 comprises a clamping wheel 54.1 which is rotatable about a clamping wheel axis 54.2.

[0246] The mixer 6 also comprises a fixed guide wall 54.3 (integrally connected to the support 31, even from the same material as the support), and a clamping wall against which the clamping wheel 54.1 rolls or slides, against which the clamping wheel is clamped in the clamping position. The clamping wall is advantageously part of the guide wall 54.3. Several variants are distinguished: a variant in which the clamping wheel 54.1 approaches the guide wall 54.3 towards the clamping position, a variant in which the distance is constant or variable, in which the clamping wall has a special recess in order to catch the clamping wheel 54.1 (this is possible due to the translationally movable clamping wheel 54.1, as will be seen below).

[0247] The teeth 54.11 present on the clamping wheel 54.1 (in practice, the wheel comprises a circular or substantially circular portion and a toothed portion, which circular or substantially circular portion clamps the first capsule 3, the toothed portion preferably being below the circular portion) can cooperate in the teeth 54.31 in the guide wall 54.3, so that the clamping wheel 54.1 rolls against the guide wall 54.3. Moreover, due to the teeth 54.11, 54.31, the clamping wheel 54.1 has a rolling movement against the clamping wall 54.3 without a sliding movement, which allows to avoid dangerous slippage with a poor clamping of the output channel 3.5. Finally, due to the teeth 54.11, 54.31, the distance between the clamping wheel 54.1 and the guide wall 54.3 (except for the teeth, i.e. the average distance) can be reduced to almost zero below the first capsule 3, while maintaining a rolling movement against the guide wall 54.3.

[0248] In order to permit this transmission, the clamping wheel 54.1 is mounted, preferably rotatably mounted, on an arm 54.5 which is itself rotatably movable about an arm rotation axis 54.51.

[0249] The arm 54.5 is integrally connected to a gear (or pulley) or gear portion 54.52, which itself is connected to the common gear 40.1 through various gears or pulleys. Thus, the arm 54.5 is rotationally driven by the same auxiliary motor 40.

[0250] In order to ensure clamping in the clamping position, including when the auxiliary motor 40 is no longer energized, the clamping wheel 54.1 is mounted movable in radial translation along the arm 54.5. A restoring mechanism 54.4 arranged between the clamping wheel 54.1 and the arm 54.5 tends to separate the clamping wheel 54.1 from the arm rotation axis 54.51 and thus tends to bring the clamping wheel 54.1 against the guide wall 54.3. More precisely, an intermediate support is provided which contains the rotation axis 54.2 of the clamping wheel 54.1. This support is movable in translation relative to the shaft 54.5. In the intermediate support, a sliding connection with a pin 54.42 sliding in a groove 54.53 of the shaft 54.5 allows guiding the translation and also advantageously allows limiting the translational movement.

[0251] The restoring mechanism 54.4 thus works in compression, wherein, by default, the restoring mechanism is not compressed (or is very little compressed). A helical spring, a leaf spring or other types of springs may be suitable.

[0252] Due to the restoring mechanism 54.4, the clamping wheel 54.1 can remain against the guide wall 54.3 even if 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 channel 3.5 is located).

[0253] Shared drive

[0254] Preferably, the holding mechanism 50, the connecting mechanism 52 and the clamping mechanism 54 are driven simultaneously by a common drive, as described according to the following embodiments. The holding mechanism 50 is driven by a gear 51 connected to at least another gear 51.1 ( Fig. 10A , 10B).

[0255] The connecting mechanism 52 is driven by a gear connected to at least one other gear, preferably the gear 51 and another gear 51.1 ( Fig. 10A , 10B).

[0256] The clamping mechanism 54 is driven by the gear portion 54 , 52 .

[0257] Different drive chains may be provided, but preferably a common gear 40.1 is provided, which then drives the further gear 51.1 and the gear section 54.52.

[0258] like Fig.11A , 11B, 11C, a common gear 40.1 is located on the output shaft of the auxiliary motor 40. This common gear meshes directly with a gear 51.1, which is mounted on a shaft including another gear 51.2. This gear 51.2 itself meshes with a gear section 54.52. Thus, there is a very simple transmission chain, which has a minimum number of gears and therefore a minimum friction loss, a minimum risk of damage, and a very small gap.

[0259] Due to this common gear 40.1 located on the output shaft of the auxiliary motor 40, at least two of the three mechanisms 50, 52, 54 are simultaneously in the insertion position or the holding position, the connection position or the clamping position. The same auxiliary motor 40 thus drives the three mechanisms, which constitutes a major simplification of the mixer 6 and its operating principle.

[0260] Visual and sound display

[0261] The mixer 6 advantageously comprises a screen 60 and / or a speaker ( FIGS. 1A , 1B, 7 ) allowing the exchange of information with the user.

[0262] The screen 60 is preferably touch-sensitive so as to avoid physical buttons. The screen allows the user to indicate the start of a cycle and the moment of removal. The screen 60 can also display the end of a cycle, for example with an audio reminder.

[0263] Power supply and control unit

[0264] According to an embodiment of the present invention, the mixer 6 further comprises a power supply (not shown in the figure), which is configured to supply power to the mixer 6, in particular to the drive motor 39 and the auxiliary motor 40. The power supply advantageously or even exclusively comprises at least one rechargeable battery 44 ( Figure 7B ). In the example shown, the rechargeable battery 44 is advantageously formed by a lithium-ion battery having two cells, which provides a nominal output voltage of 7.4V.

[0265] like Fig.12As shown, the mixer 6 also comprises a control unit 45, for example comprising a controller such as a microcontroller or processor 45.1, which is configured to control the operation of the manufacturing device 2, more specifically the operation of the drive motor 39, the auxiliary motor 40, the heating element 46, the temperature sensor and the screen 60 (preferably a processor for the screen), as well as all the sound or visual means. The control unit 45 advantageously comprises a memory 45.2 of non-volatile type, which stores instruction lines in the form of a program to be executed by the controller or processor 45.1, in particular in order to implement some of the steps described in the following method.

[0266] Other Implementations

[0267] In a variant, the holding means 5 are integrated with the mixer 6. It is therefore only necessary to insert the first or second capsule 3, 4 into the first or second receiving position 13, 14. A housing 32 is still defined which corresponds to the space occupied by the receiving means 5.

[0268] Furthermore, in this variant, the actuation surfaces 8 . 1 , 9 . 1 may not be present: the actuation members 37 , 38 in this case press directly on the first or second capsule 3 , 4 .

[0269] How to use

[0270] At least one manufacturing method for manufacturing a composition such as a cosmetic product by means of a manufacturing device 2 will now be described. The manufacturing method is broken down into a plurality of sub-methods (referred to as "methods" for reasons of clarity), and one or more variations of the method will be described. Specifically, it is divided into a preparatory method Ep, an initial method Ei, a mixing method Em, and a removal method Er.

[0271] In particular, these methods (or their variants) are advantageously implemented by means of the different embodiments of the above-described manufacturing device 2. Preferably, most of the steps of methods Ei, Em and Er are stored in a memory 45.2 of non-volatile type in the form of code line instructions executable by the processor 45.1.

[0272] The preparation method Ep comprises a preparation step Ep1 for preparing the entire use of the manufacturing device 2, which is intended to connect the manufacturing device to the grid or to charge the battery 44. Moreover, this preparation step Ep1 may be preceded or followed by a step Ep2 of placing the manufacturing device 2 on a flat support and, if necessary, having a power-on step.

[0273] The initial method Ei is then implemented. In a step Ei1 ("receiving step"), the processor of the manufacturing device 2 receives a start command. This start command is typically generated by an action of the user (contact with the touch screen 60, a button, a switch, etc.).

[0274] After this step Ei1, in a step Ei2 ("verification step"), the method ensures that the actuation system 35 is in an intermediate position that allows the insertion of the receiving means 5 or the insertion of the first and second capsules 3, 4. Typically, it should be ensured that the housing 32 (for the insertion of the receiving means 5) or the first or second receiving position 13, 14 (for the insertion of the first or second capsule 3, 4 in the absence of the receiving means 5) is not blocked by the actuation system 35. During this step Ei2, it is also suitable to check that the clamping mechanism 54, the connecting mechanism 52 and the retaining mechanism 50 are not activated, i.e. in their respective insertion positions.

[0275] After this step Ei2 , in the housing portion 32 , the receiving device 5 comprising the first or second capsule 3 , 4 may be inserted manually, or even directly.

[0276] Finally, in a subsequent step Ei3 (closing step), at least one of the clamping mechanism 54, the connecting mechanism 52 and the retaining mechanism 50 is activated, i.e. they move. This step Ei3 comprises, for example, a command from the processor to the auxiliary motor 40 in order to start the auxiliary motor so that it drives the three mechanisms, all of which are connected to a common gear (or pulley) 40.1. The auxiliary motor 40 moves from the first position to the second position so that the clamping mechanism 52, the connecting mechanism 54 and the retaining mechanism 50 move from their respective insertion positions to their respective clamping, connecting and retaining positions. Preferably, the auxiliary motor 40 remains in the second position at the end of step Ei3, even if the auxiliary motor is no longer powered.

[0277] Steps Ei1 , Ei2 , Ei3 are executed in particular by the processor 45 . 1 .

[0278] After this initial process Ei, the mixer 6 is ready to start working on the first and second capsules 3 , 4 : this is the purpose of the mixing process Em and the removal process Er.

[0279] The mixing method Em comprises a first step Em1 of the preparation phase ("initial step of moving the actuation system"), during which the connection solder of the capsule located further away from the heating element 46 (in the figure, the second capsule 4) is broken and the capsule is compressed so that the content of the capsule is partially sent towards the capsule closer to the heating element 46. According to the embodiment given, the second actuation member 38 moves in order to break the connection solder in the second capsule 4 (the second capsule, for example, comprises a formulation of an oil phase). Thus, part of the content of the second capsule 4 is sent towards one side of the first capsule 3, in particular into the connection channel 3.3 (because the connection solder of the first capsule 3 has not yet been broken). The second actuation member 38 preferably moves along its actuation stroke C38. For reasons of design simplicity, a partial stroke sensor for the second actuation member 38 is not required.

[0280] In a step Em2 of the preparation phase ("second step of moving the actuation system" or "prestressing step"), the first actuation member 37 is moved along a partial stroke strictly less than its actuation stroke C37 and maintains its position so as to exert a prestress on the first capsule 3 (which, for example, comprises an aqueous formulation) so that the flat surface 3.7 is pressed against the diffuser plate 46.2. This prestressing allows to facilitate the heat exchange between the diffuser plate 46.2 and the first capsule 3 during the subsequent step Em3 ("heating step"). It should be noted that, due to the movement of the first actuation member 37 over a partial stroke, this pressing of the first capsule 3 against the diffuser plate 46.2 is performed without causing a break in the connecting solder in the first capsule 3 (which would cause the formulation of the first capsule 3 to be sent towards the second capsule 4).

[0281] In step Em3 ("heating step") of the preparation phase, the heating element 46 is activated in order to generate heat towards the first capsule 3. Since the heating element 46 is positioned on the side of the flat face 3.7 of the first capsule 3 and the prestressing step has allowed a good thermal contact between the diffuser plate 46.2 and the first capsule 3, the heat provided by the heating element 46 is well distributed over the content of the first capsule 3. Step Em3 is therefore activated in the absence of a full movement of the actuating members 37, 38.

[0282] During a step Em3 of the preparation phase, the temperature of the heating element 46 reaches a target temperature Tc comprised between 80° C. and 90° C. The purpose of this target temperature Tc is to bring the contents of the first capsule 3 to a target temperature Tc′ also comprised between 80° C. and 90° C. and preferably of the order of 85° C. In fact, it is observed that the temperature of the contents of the first capsule 3 during this heating step Em3 corresponds approximately to the target temperature Tc of the heating element 46, however with a slight time difference.

[0283] Then, in step Em3' of the stirring phase ("mixing step"), the heating element 46 is deactivated and the first actuating member 37 is then moved along its rated stroke so as to break up the connecting solder in the first capsule 3. The interruption of the power supply to the heating element 46 before the activation of the first actuating member 37 allows to have the integrity of the power provided by the power supply source, which can be used to power the drive motor 39. This feature is particularly advantageous in the case where the mixer 6 is powered by a power converter or a battery 44 of low power. In fact, this feature allows to avoid that the power supplied to the drive motor 39 is insufficient to allow the connecting solder of the first capsule 3 to break (which causes the device to be stuck), this breaking step of the connecting solder requiring a large motor torque. When the first actuation member 37 reaches the end of its actuation stroke C37, the contents of the first capsule 3 are sent into the second capsule 4 and the two formulations can therefore circulate freely from the first or second capsule 3,4 towards the second or first capsule 4,3 via the connecting portion 3.2, 4.2 during each reciprocating movement of the actuation system 35, the connecting solder originally present in each of the first and second capsules 3,4 having been broken.

[0284] Subsequently, steps Em4, Em5, Em6 are successive steps of stirring, with or without heating (referred to as stirring phases).

[0285] The step Em4 of the stirring phase ("stirring step without heating") is intended to reciprocate the actuating members 37, 38 without activating the heating element 46, i.e. without heating. During this step, the first and second capsules 3, 4 are each deformed at least once. According to an embodiment, step Em4 lasts at least 1.4 seconds and preferably between 2 and 4 seconds. This stirring step without heating allows the drive motor 39 to be started at a constant speed, while benefiting the overall power of the power supply.

[0286] Steps Em1, Em2 and Em3, Em3', Em4 alternate the movement of the actuation system 35 and the heating by the heating element 46. This is caused in particular by the power supply dedicated to the actuation system 35 or the heating element 46. This exclusive alternation allows the battery 44 to be protected by allocating high power moments. In fact, the start of the movement causes a large resisting torque, which requires a large motor torque, and the temperature rise also requires a large power: the battery 44 is therefore strongly demanded. This alternating solution also allows the size of the components to be reduced, which is inherent in the manufacture of the mixer and the design constraints on the battery.

[0287] Conversely, once the temperature is around the target temperature Tc′ and once the actuation system 35 has arrived, the demand on the battery 44 is reduced and it is permitted to power the heating element 46 and the actuation system 35 in parallel: this is the purpose of step Em5 .

[0288] During step Em5 of the stirring phase ("stirring step with heating"), the actuation system 35 remains activated and the heating element 46 is activated in order to keep the formulation mixed at a temperature, which is preferably the target temperature Tc'. The heating element is thus kept at the target temperature Tc. This step Em5 lasts, for example, between 5 and 30 seconds and preferably between 7 and 15 seconds. Although the battery 44 is less demanded than for start-up or temperature rise, the battery may tend to discharge rapidly during this phase of limited duration.

[0289] However, this step Em5 is long enough so that the first and second capsules 3, 4 are each deformed multiple times and the emulsion obtained by mixing the preparations is satisfactory.

[0290] Between steps Em4 and Em5 , the actuation system 35 is not stopped.

[0291] Subsequently, a step Em6 of the stirring phase ("cooling step with stirring") is implemented. Alternatively, this step can be carried out without stirring, but preferably keeping the actuation system 35 activated in order to improve or maintain the homogenization of the preparation. During step Em6, the temperature of the cream decreases to a withdrawal temperature Tr', which is between 35°C and 48°C and preferably between 38°C and 42°C. In the case of the embodiment shown, the withdrawal temperature Tr' of the cream corresponds to the withdrawal temperature Tr of the heating element 46, which is between 55°C and 60°C. This temperature difference between the contents of the first and second capsules 3, 4 and the temperature of the heating element 46 during the cooling step is explained in particular by the fact that, during stirring, the composition is present only for a portion of the time in the first capsule 3 and therefore only for a portion of the time relative to the diffuser plate 46.2, where the temperature measurement is performed.

[0292] The simplest technique for cooling is to stop the power supply to the heating element 46 and let the cream cool by air at ambient temperature. Therefore, the duration of step Em6 actually depends on the ambient temperature. For this purpose, the temperature sensor is advantageously located in the mixer 6 and more precisely in the containment device 5. In order to limit the number of temperature sensors, the same sensor measures the temperature of the heating element 46.

[0293] As in the embodiment shown, a temperature sensor measures the temperature of the heating element 46, again the same sensor is used: this means that the end of step Em6 is determined by the temperature measured by said sensor, ie by a take-off temperature Tr' comprised between 55°C and 60°C.

[0294] Once the removal temperature is reached, the actuation system 35 is deactivated.

[0295] The cooling step Em6 generally lasts at least 20 seconds and preferably 40 seconds.

[0296] In a variant embodiment, step Em6 may also advantageously include a minimum stirring duration of, for example, about 40 seconds, followed by a supplementary stirring duration, which allows ensuring good emulsification, the supplementary stirring duration being only when the removal temperature Tr' has not yet been reached. On the other hand, even if the temperature is less than the removal temperature Tr', stirring is still carried out during a certain duration.

[0297] It should be noted that, according to an embodiment not shown, the mixer 6 may include a cooling system for cooling the cream in an effective manner and accelerating the process. For example, a cooling system equipped with a small-sized fan may be provided, with or without the addition of a cooling element, which forces air to circulate in the mixer 6, thus forcing cooling by intensive convection.

[0298] Once the mixing method Em is finished, the removal method Er can be started. This removal method Er will now be described.

[0299] Since the above steps take some time (usually more than one minute), the user may not be near the mixer 6 but busy with his daily affairs (eating breakfast, listening to the radio, watching TV, buttering bread, getting dressed, ironing clothes, etc.). Therefore, it is important that the mixer 6 can keep the cream in a ready-to-use state for a predetermined duration.

[0300] To this end, in step Er1 ("transfer step for storage"), the actuation system 35 is activated once to transfer the cream into the capsule (ie here the first capsule 3) situated on the side of the heating element 45. This step is optional once step Em6 has been stopped in a good configuration.

[0301] In step Er2 ("prestress maintenance step"), the actuation system 35 is again in the prestressed position, wherein the first actuation member 37 exerts a prestress on the first capsule 3 so as to bring it against the diffuser plate 46.2, and then, in step Er3 ("warming step"), the heating element 46 is activated so as to keep the cream at the removal temperature Tr'. Step Er2 for maintaining the prestress allows better heat conduction, as in step Em2. Preferably, the stirring or movement of the actuation system 35 is periodically implemented during step Er3 in order to ensure good emulsification, which can be partially impaired by the presence of hot spots on the diffuser plate 46.2.

[0302] In a variant implementation, the removal method may comprise, instead of step Er2, a step Er2' ("maintenance step of the intermediate position"), in which the actuation system 35 is activated so as to be placed in an intermediate position, i.e. without forcing the first or second capsules 3, 4 and in particular the first capsule 3 against the heating element 46. Surprisingly, this variant allows to maintain a better emulsification and avoids agitation of the use cycle during the holding phase.

[0303] Step Er3 is implemented during a predetermined waiting duration, which is less than 15 minutes so as not to power the heating element 46 for too long, and which is greater than 1 minute and preferably about 5 minutes so as to allow flexibility for the user in the morning time management.

[0304] On the other hand, this means that after the movement of the actuation system 35 has ended, the user has between 1 minute and 15 minutes and preferably about 5 minutes (depending on the factory parameter selection or the user's parameter selection) to restore the cream to a good temperature.

[0305] As soon as the user is ready to use the cream, he touches the touch screen or presses a button, which starts step Er4 ("step of receiving the removal instruction"), during which the mixer 6 receives the removal command.

[0306] Then, in step Er5 (“step of placing in the intermediate position”), the actuation system 35 is activated so as to be placed in the intermediate position.

[0307] In the case where the actuation system 35 is prestressed at the first actuation member 37, the first actuation member should end its movement, which moves the formulation to the second capsule 4, and then the actuation system 35 stops in an intermediate position corresponding to a position suitable for removing the receiving device 5. This position also corresponds to a starting position suitable for implementing the next manufacturing cycle implementing the above method. In fact, starting from the start of the drive motor 39, the second actuation member 38 is ready to compress the second capsule 4 at step Em1.

[0308] In the case of implementing a variant example, the actuation system 35 is already in an intermediate position at step Er2', so as to keep warm at step Er3, it may be necessary for the actuation system 35 to perform a reciprocating motion so as to be positioned in an intermediate position suitable for implementing the next manufacturing cycle of the above-mentioned method, that is, the second actuation member 38 is ready to compress the second capsule 4 at step Em1.

[0309] During this reciprocating movement of the actuation system 35 , the cream present in the first capsule 3 is partly sent into the second capsule.

[0310] Finally, in a final step Er6 (unlocking step), each mechanism activated in step Ei3 is placed in the insertion position. Likewise, this step Er6 implies the activation of the auxiliary motor 40 .

[0311] Subsequently, the user grabs the receiving device 5 and removes it from its housing 32. Then, the user presses the actuation surfaces 8.1, 9.1 in order to pivot the blades in order to expel the cream present in the first and second capsules 3, 4 through the outlet channel 3.5 of the first capsule 3. Finally, what has to be done is to remove the first or second capsule 3, 4 from the receiving device 5 so that the receiving device is ready for use again. In fact, no part of the mixer 6 (the manufacturing device 2 or the receiving device) comes into contact with the preparation.

[0313] Ei1: a receiving step (implemented by the mixer and more precisely by the processor) of receiving a start command;

[0314] Ei2: positioning step of the actuation system (implemented by the mixer and more precisely by the processor controlling the drive motor);

[0320] Em4: a non-heating stirring step for starting the motor at a constant speed (implemented by the mixer and more precisely by the processor controlling the drive motor);

[0321] Em5: stirring step with heating for achieving emulsification (implemented by the mixer and more precisely by the processor controlling the drive motor and the heating element);

[0322] Em6: cooling step with stirring and without heating (cooling) to the take-out temperature (implemented by a mixer, the processor of the mixer controlling the drive motor);

[0323] Er1: optional step for transfer of storage by movement of the actuation system (implemented by the mixer and more precisely by the processor controlling the drive motor);

[0324] Er2: a step of placing the actuation system in a prestressed position (implemented by the mixer and more precisely by the processor);

[0325] Er2': a step (which may replace step Er2) of placing the actuation system in an intermediate position (implemented by the mixer and more precisely by the processor controlling the drive motor);
