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, the manufacturing device comprising:

[0003] a first capsule, which includes a first compartment and a first connection part, the first compartment including a predetermined amount of a first preparation;

[0004] a second capsule, which includes a second compartment and a second connection part, the second compartment including a predetermined amount of a second preparation, the second connection part being configured to be connected to the first connection part; and

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

[0006] The mixer particularly includes:

[0007] a first pressing element, which includes a first pressing surface configured to apply a pressure on the deformable first compartment of the first capsule, the pressure being perpendicular to the moving direction of the first pressing element;

[0008] a second pressing element, which includes a second pressing surface configured to apply a pressure on the deformable second compartment of the second capsule, the pressure being perpendicular to the moving direction of the second pressing element; and

[0009] a drive motor, which 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 end consumers to manufacture personalized cosmetic products 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, the pressure being suitable for ensuring the movement of the content from the first compartment towards the second compartment and conversely the movement of the content from the second compartment towards the first compartment, especially when the deformable first and second compartments or the connection channels connected to the deformable first and second compartments are closed by weak connection areas.

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

[0013] In addition, the mixing of the capsules appears to be more complex than expected and both the materials and the way they are used need to be improved. Summary of the Invention

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

[0015] Therefore, the technical problem underlying the present invention is to provide a device for manufacturing a composition, which is simple, compact and easy to use, while having a simple and cost-reduced structure.

[0016] In particular, it is difficult to obtain an actuation system that transmits a regular movement without generating undesirable noise and does not give the impression of a fragile system. In addition, considering the compactness of the device and the conditions of use (the device is transported in a bag, dropped, misused), the kinematic chain for transmitting the movement from the electric motor to the actuation system should meet the above requirements.

[0017] To this end, the present invention proposes a mixer configured to receive a receiving device to form a manufacturing device, the mixer comprising:

[0018] - a support member defining a receiving portion adapted to receive a first capsule and a second capsule, the first capsule and the second capsule being deformable and adapted for fluid connection with each other, the first and second capsules containing a first preparation and a second preparation respectively;

[0019] - an actuation system that can reciprocally rotate about a pivot axis;

[0020] - a cam that can rotate and move along a cam rotation axis that is not parallel to the actuation rotation axis, the cam including a drive finger;

[0021] wherein the actuation system includes a drive groove configured to receive the drive finger such that rotation of the cam causes reciprocating movement of the actuation system,

[0022] wherein the connection between the drive finger and the drive groove includes a ball-and-socket connection.

[0023] In one embodiment, the connection between the drive finger and the drive groove further includes a sliding connection.

[0024] In one embodiment, the connection between the drive finger and the groove further includes another sliding connection in another direction.

[0025] In one embodiment, the two sliding connections are made along the length direction of the groove and along the direction of the sliding finger.

[0026] In one embodiment, the connection includes a ring that is translatably movable in the drive groove, and a ball-and-socket connection is defined between the ring and the drive finger.

[0027] In one embodiment, the connection includes a ball that is translatably mounted on the drive finger.

[0028] In one embodiment, the ball-and-socket connection is achieved by the ball and the ring.

[0029] In one embodiment, the pivot axis is located on one side of the receiving portion, and the cam is located on the other side of the receiving portion.

[0030] In one embodiment, the pivot axis is orthogonal to the cam rotation axis.

[0031] In one embodiment, the maximum angular stroke of the rotation of each actuating member is less than 45°, preferably equal to 30°.

[0032] In one embodiment, the cam is driven by a drive motor that is configured to rotate only in a single direction.

[0033] In one embodiment, the actuating members share the same pivot rotation axis.

[0034] In one embodiment, each actuating member has its own pivot axis, and two rotating members are rotatably movably mounted using a connecting member, preferably by a hinge.

[0035] In one embodiment, the actuating system surrounds the receiving portion.

[0036] In one embodiment, the actuating system includes:

[0037] - A first actuating member that is positioned on one side of the receiving portion and is movable within the receiving portion to transfer pressure to the first side of the receiving device;

[0038] - A second actuating member that is positioned on the preferably opposite other side of the receiving portion and is movable within the receiving portion to transfer pressure to the second side of the receiving device;

[0039] wherein the two actuating members are reciprocally rotatably movable about an actuating rotation axis and are rotationally connected as a unit through a connecting portion,

[0040] Wherein, the driving groove is positioned in the connecting portion.

[0041] The present invention also provides a manufacturing device, comprising:

[0042] - a mixer as described above, and

[0043] - a storage device configured to store a first capsule and a second capsule, the first capsule and the second capsule being deformable and adapted for fluid connection with each other, the first and second capsules respectively containing a first preparation and a second preparation;

[0044] Wherein, the storage device is configured to be placed in the receiving portion of the mixer. BRIEF DESCRIPTION OF THE DRAWINGS

[0072] Figure 1A And Figure 1B Shows a manufacturing device 2 according to a first embodiment of the present invention, which is configured to manufacture a composition, which can be, for example, a beauty product, a hair care product, a pharmaceutical product, a sterilizing product, a maintenance product, a cleaning product or an agricultural and food product. When the composition to be manufactured is a beauty product, the beauty product can be, for example, a homogeneous emulsion, a homogeneous solution or a mixture of multiple soluble phases.

[0073] The manufacturing device 2 is for mainly personal use and for small size: the manufacturing device 2 allows the manufacture of a single ready-to-use portion. Therefore, the size of the manufacturing device should meet the volume limitations in bathrooms, beauty salons, luggage (for transportation), etc. Therefore, the manufacturing device 2 does not have a size greater than 40 cm.

[0074] The manufacturing device 2 includes a storage mechanism and a mixer 6. The storage mechanism is configured to store first and second capsules 3, 4, which are also referred to as tablets or encapsulation units. The first and second capsules respectively include a predetermined amount of a first preparation and a predetermined amount of a second preparation. The mixer is configured to mix the first and second preparations contained in the first and second capsules 3, 4 stored in the manufacturing device 2 in order to obtain a beauty product.

[0075] The mixer 6 includes a receiving portion which is part of the storage mechanism and is arranged to receive the first and second capsules 3, 4 directly or via a specific storage device 5.

[0076] In a preferred embodiment, especially visible in all of the attached Figure 1A , Figures 1B, 7A, 8A, 8B, 8C, the mixer 6 includes a receiving portion 32 which is capable of removably receiving the storage device 5. In this case, the receiving portion 32 has a shape that is generally complementary to the shape of the storage device 5.

[0077] The mixer 6 further includes an actuating system 35 which is configured to apply a force on the first and second capsules 3, 4, if necessary via the storage device 5, in order to allow the mixing and stirring of the composition to be manufactured.

[0078] The storage device 5 is also referred to as a shuttle (since this storage device serves as a carrier for the first and second capsules 3, 4), and preferably has a relatively symmetric shape, such as a parallelogram or an elliptical / oval shape. A longitudinal direction X can be defined for the storage device, which corresponds to a direction along which the storage device is inserted into the receiving portion 32. Thus, when the storage device 5 is inserted into the mixer 6, the longitudinal direction X and the insertion direction coincide.

[0079] Advantageously, the mixer 6 is configured to mix the first and second preparations inside the storage device 5 and preferably inside the first and second capsules 3, 4, without any preparation coming into contact with the manufacturing device 2.

[0080] As pointed out above, some of the embodiments present here can be used for a manufacturing device 2 without a storage device 5, that is, where the first and second capsules 3, 4 can be directly positioned in the mixer.

[0081] Advantageously, the first preparation is the first phase of the beauty product to be manufactured, such as the oil phase of the beauty product, while the second preparation is the second phase of the beauty product, such as the water phase of the beauty product. For example, the oil phase can constitute the matrix of the beauty product to be manufactured, and the water phase can include active ingredients and thus constitute the active complex of the beauty product to be manufactured.

[0082] Capsule

[0083] Two capsules can be used in the manufacturing device 2 given, which is described in detail in the document submitted under application number FR1755744, and the description content about the capsules is included herein.

[0084] The capsules are thus not the object of the present invention. For the following description, the following key points will be reviewed.

[0085] More specifically, as Figure 2A , shown in 2B, 3A, 3B, 4A, 4B, the first and second capsules 3, 4 are different from each other and are configured to be fluidly connected to each other. In addition, each of the first and second capsules 3, 4 is advantageously disposable.

[0086] The first capsule 3 includes a first deformable compartment 3.1 having a raised shape, a first connecting portion 3.2 and a first connecting channel 3.3. The first deformable compartment contains a first preparation. The first connecting channel is configured to fluidly 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 pipe. The first connecting portion 3.2 more specifically includes, for example, a female connecting joint 3.4 having a cylindrical shape, and the female connecting joint is fluidly connected to the first connecting channel 3.3. The first capsule 3 includes a flat surface 3.7, and the first connecting portion 3.2 passes through the flat surface.

[0087] The first capsule 3 further includes an output channel 3.5, such as an output pipe, which is fluidly connected to the first connecting 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 connecting channel 3.3 and extends substantially parallel to the first connecting channel 3.3. In this case, the output channel 3.5 can be installed on the first capsule 3 or the second capsule 4 indifferently. In fact, the output channel 3.5 is only required to work when the manufacturing device 2 is used.

[0088] The second capsule 4 includes a second deformable compartment 4.1 having a raised shape, a second connecting portion 4.2, and a second connecting channel 4.3. The second deformable compartment contains a second preparation. The second connecting portion 4.2 is configured to be connected to the first connecting portion 3.2, and the second connecting channel is configured to fluidly 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 pipe, and the second connecting portion 4.2 extends substantially perpendicular to the second connecting channel 4.3. The second connecting portion 4.2 more particularly includes, for example, a male connecting joint 4.4 having a cylindrical shape. The male connecting joint is fluidly connected to the second connecting channel 4.3 and is configured to receive the female connecting joint 3.4 in a sealed manner. The second capsule 4 includes a flat surface 4.7, and the second connecting portion 4.2 passes through the flat surface.

[0089] The first and second capsules 3, 4 and more particularly the first and second deformable compartments 3.1, 4.1 are each closed by a connecting solder ensuring the hermeticity of the first and second capsules 3, 4. These connecting solders are fragile as long as a pressure threshold is reached. These pressure thresholds can be reached in the mixer 6. Moreover, these connecting solders are described in detail in the description of the document filed under application number FR1755744.

[0090] Each of the first and second capsules 3, 4 is configured to contain the whole or an approximation of the whole of a mixture formed by a predetermined quantity of a first preparation and a predetermined quantity of a second preparation. To this end, the deformable compartments are flexible and are provided with buffer zones. Moreover, the description of the document filed under application number FR1755744 describes this precisely.

[0091] Storage device

[0092] More particularly, as Figure 2A , shown in 2B, 3A, 3B, 4A, 4B and 5, the receiving device 5 is capable of occupying an open position and a closed position. In the open position, the first and second capsules 3, 4 can be introduced into the receiving device 5. In the closed position, the receiving device 5 is capable of holding the first and second capsules 3, 4 in place.

[0093] The receiving device 5 more particularly takes the form of a receiving box 7 ( Figure 2A , 2B), which is configured to at least partially receive and accommodate the first and second capsules 3, 4. The receiving device 5 particularly includes a first protective shell 8 and a second protective shell 9, which rotate about a hinge axis 10 (or hinge) between a first position (see Figure 2A , 2B, 5) and a second position ( Figure 4A, are pivotally mounted relative to each other between (4B), the first position corresponding to the open position of the storage device 5, and the second position corresponding to the closed position of the storage device 5. The storage device 5 further includes a first support portion 11 and a second support portion 12 disposed 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 being configured to store the first capsule 3, and the second storage position being configured to store the second capsule 4. Each of the first and second protective shells 8, 9 includes 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 the insertion surface of the storage device 5. The storage device 5 includes a removal surface opposite to the insertion surface.

[0094] Advantageously, the first support portion 11 includes a storage gasket 15 configured to receive the peripheral portion of the capsule 3, and the second support portion 12 also includes a storage gasket 15 configured to receive the peripheral portion of the second capsule 4. These storage gaskets 15 partially define the first and second storage positions 13, 14.

[0095] The first support portion 11 includes a first placement surface 11.1 configured to guide (with contact) and receive the flat surface 3.7 of the first capsule 3. The first placement surface 11.1 thus partially defines the first storage position 13.

[0096] In the same manner, the second support portion 12 includes a second placement surface 12.1 configured to guide (with contact) and receive the flat surface 4.7 of the second capsule 4. The second placement surface 12.1 thus partially defines the second storage position 14.

[0097] When the first and second capsules 3, 4 are inserted, their respective flat surfaces 3.7, 4.7 face each other, and there are two placement surfaces 11.1, 12.1 between the flat surfaces.

[0098] To allow the first and second connection portions 3.2, 4.2 of the first and second capsules 3, 4 to pass through, each of the first and second placement surfaces 11.1, 12.1 includes a through-opening 11.2, 12.2, the through-opening having a notch form and opening towards the outside along the insertion axis X ( Figure 1A )

[0099] The storage device 5 further includes a partition wall 22 that defines a partition surface ( Figure 3A, 3B). The partition wall 22 is located between the first and second receiving positions 13, 14. The partition wall is also integral with the first support portion 11. The partition wall 22 includes an opening 22.2 to allow the first and second connecting portions 3.2, 4.2 to be positioned in the receiving device. The opening 22.2 has the form of a through-cut in thickness and is open on the outside.

[0100] 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.

[0101] In addition, a first actuating surface 8.1 and a second actuating surface 9.1 are defined. The first actuating surface includes the first shell 8 and the first support portion 11, and the second actuating surface includes the second shell 9 and the second support portion 12.

[0102] Each actuating surface 8.1, 9.1 participates in the transmission of the force received by the receiving device 5 towards the first and second capsules 3, 4. This will be explained in detail below.

[0103] Hinged

[0104] According to the embodiment visible in Figure 2A , 2B, 3A, 3B, 5, the first and second shells 8, 9 are hinged relative to each other about a hinge axis 10 and between a receiving position (see Figure 2A , 2B, 3A, 3B) and a connecting position (see Figure 4A , 4B). In the receiving position, the first and second shells 8, 9 are away from each other, and the first and second capsules 3, 4 can be respectively received in the first and second receiving positions 13, 14. In the connecting position, the first and second shells 8, 9 are close to each other, and the first and second capsules 3, 4 are pre-connected to each other. Being pre-connected to each other means that the male connecting joint 4.4 of the second capsule 4 is partially inserted into the female connecting joint 3.4 of the first capsule 3, without establishing a sealed connection between the first and second capsules 3, 4.

[0105] When the first and second shells 8, 9 are in the receiving position, the first and second shells 8, 9 can have an inclination angle greater than or equal to 7° and for example about 7°. When the first and second shells 8, 9 are in the connecting position, the first and second shells 8, 9 are substantially parallel to each other. More precisely, there are two main wholes 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.

[0106] Advantageously, the first and second housings 8, 9 (or the actuating surfaces 8.1, 9.1) are configured such that when the receiving device 5 is moved to the closed position, the first connecting portion 3.2 is inserted into the second connecting portion 4.2. In fact, when the first and second housings 8, 9 are in the closed position, the connecting portions 3.2, 4.2 are partially nested with each other.

[0107] The first and second support portions 11, 12 are more specifically configured such that when the first and second housings 8, 9 are in the connected position, the first and second capsules 3, 4 extend substantially parallel to each other. As Figure 4A , as shown in FIG. 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.

[0108] Heating element

[0109] The manufacturing device 2 includes a heating element 46 visible in Figure 3A , FIG. 3B. In the embodiment described in the figure, the heating element 46 belongs to a part of the receiving device 5. However, in the absence of the receiving device 5, this heating element can be integrated with the mixer.

[0110] The heating element 46 is fixed to the partition wall 22. In the design, it has been selected that the heating element 46 is on the side of the first support portion 11, which means that the heating element 46 is mounted on the side of the partition wall 22 on the side of the first support portion 11.

[0111] The heating element 46 preferably includes 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 heat. If possible, the heating element has an area of at least 500 mm 2 and preferably about 800 mm 2 .

[0112] 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 communicates the flat surface 3.7 of the first capsule 3 with the heating element 46 (i.e., separated only by air).

[0113] Electric contact track of the heating element

[0114] The heating element 46 needs to be powered. Preferably, the receiving device 5 does not include its own battery and should be powered when the receiving device is inserted into the receiving portion 32.

[0115] Therefore, the electrical connection is provided between the storage device 5 and the mixer 6.

[0116] The storage device 5 includes an insertion face and a removal face. The openings 8.2, 9.2 are located on the insertion face, and this insertion face is the face that first enters the receiving part 32. The removal face is opposite to the insertion face and is the face visible when the storage device 5 is inserted into the receiving part 32. The storage device 5 also includes opposite first actuation faces 8.1 and second actuation faces 9.1.

[0117] Finally, the storage device 5 includes preferably opposite first connection faces 23 and second connection faces 24. In the embodiments shown in Figure 2A , 2B, 3A, 3B, 4A, 4B, the connection faces 23 and 24 correspond to the sides of the heating element 46 and are thus different from the first and second actuation faces 8.1, 9.1 and the insertion / removal faces.

[0118] The connection faces 23, 24 extend between the actuation faces 8.1, 9.1 of the storage device 5. Preferably, the actuation faces 8.1, 9.1 of the storage device 5 are connected between the connection faces 23, 24, that is, they are adjacent.

[0119] The general shape of the storage device 5 is chosen such that the connection faces 23, 24 are spaced more than the actuation faces 8.1, 9.1 (and more than the insertion / removal faces). On the other hand, if the smallest parallelepiped into which the storage device 5 is inserted is considered, the face in contact with the connection faces 23, 24 is farther away than the face in contact with the actuation faces 8.1, 9.1 and closer than the face in contact with the insertion / removal faces. This results from the fact that the width of the storage device is greater than its thickness (moreover, the height is greater than the width).

[0120] The first connection face 23 includes a first electrical contact track 23.1 for powering the heating element 46, and the second connection face 24 includes a second electrical contact track 24.1 also for powering the heating element 46 ( Figure 2A , 3A, 3B, 4A, 4B). The electrical contact tracks 23.1, 24.1 are thus outside the storage device 5 in order to come into contact with complementary tracks ( Figure 2A , 4A, 4B).

[0121] This configuration has several advantages: First, this configuration ensures a simple and effective electrical connection. This configuration also avoids the risk of short - circuit. In fact, once a liquid flows in the receiving part 32 (for example, the water in a shower or sink or simply a broken capsule), it is impossible for the two electrical contact tracks 23.1, 24.1 to come into contact with the same amount of liquid simultaneously.

[0122] The first connection face 23 includes a first and a second shell 8, 9, a first support part 11 and a part of the partition wall 22.

[0123] Specifically, the first connection surface 23 includes 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 wall 23.22 of the longitudinal groove 23.2. In Figure 3A the embodiment shown in FIGS. 3A and 3B, the bottom 23.21 and the side wall 23.23 are formed by a part of the first support portion 11. A suitable cutout 8.5 is thus provided in the first housing 8 to make room for the longitudinal groove 23.2. The opposite side wall 23.22 is formed by a part of the partition wall 22. The first electrical contact track 23.1 is thus positioned on this side wall 23.22 (since the heating element 46 is mounted on the partition wall).

[0124] Similarly, a similar longitudinal groove 24.2 is provided on the second connection surface 24, which has a cutout 9.5 in the second housing 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 housing 9 is significantly less obvious than the cutout 8.5 in the first housing 8.

[0125] The grooves 23.2, 24.2 are configured to engage on respective complementary guide rails 31.1, 31.2 (sliding connection) provided in the receiving portion 32 and on the (preferably opposite) connection sides ( Figure 1A , FIGS. 7A). Thus, the grooves 23.2, 24.2 form a cutting portion that extends over the entire height of the part of the receiving device 5 in which the grooves are located, at least up to the insertion height. The complementary guide rails 31.1, 31.2 help to define the receiving portion 32 and are positioned on opposite edges.

[0126] In the embodiment especially visible in Figure 4A , FIGS. 4B, the electrical contact tracks 23.1, 24.1 are not in the same horizontal plane but are offset.

[0127] The electrical contact tracks 23.1, 24.1 can take various forms: electric pins, metal sheets (as shown), etc. The electrical contact tracks 23.1, 24.1 are preferably slightly deformable to ensure a lasting contact when the receiving device 5 is placed in the receiving portion 32.

[0128] Thus, it is noted that the longitudinal grooves 23.2, 24.2 are not centered with respect to the first and second actuating surfaces 8.1, 9.1 (especially see Figure 2A , FIGS. 4A, 4B). In terms of the design, this is caused by the grooves mainly formed in the first support portion 11 and the first protective housing 8.

[0129] The benefit of this asymmetry lies in the positioning function. In fact, it is impossible to place the receiving device 5 in the wrong direction (rotated 180° around the longitudinal axis X) because the grooves 23.2, 24.2 cannot be inserted into the guide rails 31.1, 31.2, and the second housing 9 abuts against the guide rails 31.1, 31.2.

[0130] For there to be a positioning effect for vertical rotation (i.e., trying to place the removal face first instead of the insertion face), the longitudinal grooves 23.2, 24.2 do not extend over the entire height of the part of the first or second housing 8, 9 in which they are located. Thus, there is no need to provide a dedicated part, and the stop effect is simply obtained by the part of the first or second housing 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 housing 8, 9 prevents the insertion of the grooves 23.2, 24.2 onto the guide rails 31.1, 31.2.

[0131] In addition, the longitudinal grooves 23.2, 24.2 each include end stops 23.3, 24.4 located on the side of the removal face. These end stops 23.3, 24.4 act as insertion stops in order to define the maximum insertion position in the receiving part 32.

[0132] In fact, there are two different types of stops, and they are roughly located in the same position: at the ends of the longitudinal grooves 23.2, 24.2.

[0133] Electric contact track of the temperature sensor

[0134] Because of the heating element 46 for primarily heating the first capsule 3, the first support part 11 is preferably over the second support part 12 in order to support the walls 23.23, 24.23 of the grooves 23.2, 24.2.

[0135] In fact, a temperature sensor (not shown in the figure) is connected to the back of the diffusion plate 46.2 in order to measure the temperature near the first receiving position 13 and thus near the first capsule 3.

[0136] The temperature sensor is typically a CTN (negative temperature coefficient thermistor).

[0137] This temperature sensor should also be electrically connected to the mixer 6 (especially ultimately connected to a processor in order to collect data) and to the battery 44 provided in the mixer 6 in order to power this temperature sensor. For this purpose, a first supplementary electrical contact track 46.51 is provided at the first contact surface 23. This first supplementary electrical contact track 46.51 is different from the first electrical contact track 23.1. More precisely, the first supplementary electrical contact track 46.41 is provided in the first groove 23.2, on the side wall 23.23, i.e., on the side wall formed by the first support part 11.

[0138] Similarly, a second supplementary electrical contact track 46.52 is provided in the second groove 24.2.

[0139] The two supplementary electrical contact tracks 46.51, 46.52 are also advantageously offset. In a particular example, the supplementary electrical contact track 46.51 and the electrical contact track 24.1 are in the same horizontal plane, and the supplementary electrical contact track 46.52 and the electrical contact track 23.1 are in the same horizontal plane.

[0140] Figure 2A , 3A, 3B, 4A, 4B, 5 show these tracks.

[0141] Positioning part

[0142] The receiving device 5 includes a positioning part 17 which is used to ensure the correct positioning of the first and second capsules 3, 4, that is, the "correct" capsules 3, 4 are placed in the "correct" receiving positions 13, 14 (differently visible in Figure 2A , 5). The positioning part 17 is preferably located at the end of the openings 11.2, 12.2 so as to prevent the unwanted passage of the unwanted connecting joints 3.2, 4.2.

[0143] The positioning part 17 includes at least one door leaf 17.1 which opens towards the outside of the receiving device 5 (preferably two door leaves on each side, as shown in the figure; preferably, the two door leaves 17.1 have a bar configuration, that is, they are hinged towards the outside of the receiving device).

[0144] Specifically, the positioning part 17 serves two different functions.

[0145] The door leaf 17.1 includes an opening 17.2 which has a shape complementary to the female connecting joint 3.4 of the first capsule 3 so as to allow it to be inserted into the opening 8.2. In addition, the door leaf 17.1 includes a stop 17.3 which helps to define the opening 17.2 so as to prevent the second connecting part 4.2 which is laterally longer than the first connecting part 3.2 from being inserted into the opening 8.2. In fact, if an attempt is made to insert the second capsule 4 into the first receiving position 13, the end of the second connecting part 4.2, that is, a part of the male connecting joint 4.4 abuts against the stop 17.3.

[0146] For entry into the second receiving position 14, when the receiving device 5 is in the closed position, the positioning part 17 blocks the second receiving position: it is blocked by the opening 12.2 and preferably also by the stop 17.3. Conversely, when the receiving device 5 is in the open position, that is, when the second shell 9 rotates on its hinge, it is released through the opening 12.2.

[0147] Finally, since the door leaf 17.1 opens towards the outside, when the first and second capsules 3, 4 are removed from the storage device 5 (both at the same time since they are fixed together), they are not functionally obstructed.

[0148] According to the design of the relative movement of the parts, the positioning part 17 can be fixed to the first support part 11 or the second support part 12 (as shown in the drawings): if the second support part 12 is fixed to the second housing 9 (and thus rotatable relative to the first support part 11), then preferably the positioning part is fixed to the first support part 11. In other words, it makes no difference.

[0149] The return spring 17.4 holds the positioning part 17 in the default position, i.e., the closed position.

[0150] Pressing element - vane

[0151] Especially as Figure 2B , 3A, 3B, 5 show, the storage device 5 further 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, 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.

[0152] The first pressing element 19 (or the second pressing element 21) is preferably mounted on the first support part 11 (or the second support part 12), and is movable between an ineffective position, i.e., the deployed position and an effective position, i.e., the folded position, in which ineffective position the first or second storage position 13, 14 is easily accessible for the first or second capsule 3, 4 (see Figure 2B , 3A, 3B), and in which 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), i.e., the first pressing element (or the second pressing element) is able to apply 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).

[0153] The first pressing element 19 (or the second pressing element 21) is advantageously mounted rotatably about a hinge 19.1 (or a hinge 21.1). The hinge 19.1 (or the hinge 21.1) is located opposite the opening 8.2 (or the opening 8.1) of the first housing 8 (or the second housing 9). The hinges 19.1, 21.1 are thus both located near the extraction face of the storage device 5.

[0154] The pressing elements 19, 21 each have a flat inner surface 19.2, 21.2 so as to form a rotatable blade. Each flat inner surface 19.2, 21.2 cooperates with its first or second capsule 3, 4 respectively. As pressure is applied to the pressing element, the space between the blade and the placement surfaces 11.1, 12.1 gradually and continuously decreases. When the first or second capsule 3, 4 is installed, the outlet hole 3.6 and the connection parts 3.2, 4.2 are located on opposite sides of the hinge 10: This allows the cream in the first or second capsule 3, 4 to be effectively expelled while avoiding any unwanted retention areas inside the first or second capsule.

[0155] To hold the pressing elements 19, 21 in the default open position (i.e., when the dispensing device 5 is not actuated or when the second housing 9 is in the pivoted position), a restoring mechanism 21.3, such as a spring, is provided against the first or second housing 8, 9 ( Figure 5 ). The restoring mechanism 21.3 can tend to push the blade that extends slightly on the other side of the hinge 21.1.

[0156] In use, as will be described subsequently, the two pressing elements 19, 21 are actuated in sequence to allow the cream to be agitated. Accordingly, the cream is transferred from the first or second capsule 3, 4 to the other second or first capsule 4, 3.

[0157] Preferably, to optimize the operation of the blade, the hinge 19.1 (or hinge 21.1) defines a rotational axis that is contained in the plane of the placement surface 11.1 (or placement surface 12.1) and perpendicular to the longitudinal axis of the dispensing device 5. In the absence of a capsule, the inner surfaces 19.2, 21.2 can abut against the placement surfaces 11.1, 12.1.

[0158] Similarly, the hinges 19.1, 21.1 are preferably located just at the ends of the first or second receiving positions 13, 14.

[0159] To move the pressing elements 19, 21, the first and second housings 8, 9 preferably each include a pressing point 8.3, 9.3 on the opposite side of the end of the blade (to utilize the lever effect and minimize the force to be applied), and the pressing points are configured to receive an external force, which will be described in more detail later. The pressing points 8.3, 9.3 are fixed to flexible areas 8.4, 9.4, which are deformable (made of an elastomer, etc.). The flexible areas 8.4, 9.4 are themselves fixed to the remaining parts of the first or second housing 8, 9 made of a more rigid plastic.

[0160] The pressing points 8.3, 9.3 are made of a rigid material (typically plastic).

[0161] Alternatively (not shown), the first and second housings 8, 9 have two holes, preferably opposite the ends of the blades, to allow free access to the pressing elements 19, 21.

[0162] The user can grasp the receiving device 5 with the hand and simultaneously press the pressing points 8.4, 9.4, for example, with the thumb and index finger / middle finger. The simultaneous pressure allows the cream of the first and second capsules 3, 4 to be directed towards the outlet hole 3.6.

[0163] In another embodiment (not shown), the receiving device 5 is integrated with the mixer 6, and the blades can be directly integrated in the mixer 6.

[0164] Retention stop

[0165] 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 more detail later, is provided in the manufacturing device 2. In order for the holding mechanism 50 to have a support point on the receiving device 5, a holding stop 9.6 is provided on one of the first or second housings 8, 9 (on Figure 2A , 2B, 3A, 3B, 4B, 5 it is the second housing 9). The holding stop 9.6 mainly corresponds to a radially extending protrusion, i.e., a protrusion extending in a plane perpendicular to the longitudinal direction X. The holding stop can be located at any position along the height of the receiving device 5. In the illustrated embodiment, the holding stop 9.6 is provided near the insertion surface.

[0166] For example, for ergonomic reasons, another stop can be provided on the other housing.

[0167] Grip handle

[0168] To allow the user to hold the receiving device 5 when it is inserted into the receiving portion 32, gripping handles 8.7, 9.7 are provided on each of the first and second protective housings 8, 9 (visible especially in FIGS. 1, 2B, 4A, 4B). These gripping handles 8.7, 9.7 are located at the removal surface, which is the surface that can be accessed when the receiving device 5 is placed.

[0169] The gripping handles 8.7, 9.7 can simply be formed by radially extending protrusions, i.e., protrusions extending in a plane perpendicular to the longitudinal direction X, and are long enough for a part of the user's finger joint to be lifted above.

[0170] Connection button

[0171] As pointed out above, the actuating surfaces 8.1, 9.1 and more particularly the first and second protective shells 8, 9 each include pressing points 8.3, 9.4 for transmitting a force towards the internal pressing elements 19, 21. These pressing points 8.3, 9.4 are formed in the flexible regions 8.4, 9.4.

[0172] When the receiving device 5 is moved to the closed position, the connection joints 3.4, 4.4 face each other and are 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 towards the receiving device 5. The connection mechanism 52 simultaneously allows a fluid connection to be established between the first and second capsules 3, 4 under the action of the force applied by the connection mechanism 52, and also allows any undesired disconnection between the first and second capsules 3, 4 under the pressure generated by the agitation of the first and second capsules 3, 4 to be avoided. This will be described later.

[0173] One (or even both) of the first or second protective shells 8, 9 includes a connection button 9.8 that moves towards the second receiving position 14 ( Figure 2A , 2B, 3A, 3B, 4A, 4B, 5). More precisely, the connection button moves towards the region near the opening 9.2 because the connection button 9.8 is used to press the second capsule 4 near the connection portion 4.2. For this purpose, the connection button 9.8 is fixed to the flexible region, which may be the flexible region 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.

[0174] 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, and thus the first and second capsules are kept connected.

[0175] Mixer

[0176] More specifically, as Figure 6 , 7A, 7B, 8A, 8B, 8C, 9, 10A, 11A, 11B, 11C shows, the mixer 6 includes a support portion 31 and a receiving portion 32, the receiving portion being at least partially defined by the support portion 31 and configured to at least partially receive the receiving device 5. According to Figure 1A, in the embodiment shown in 1B, the mixer 6 and the storage device 5 are configured such that when the storage device 5 is received in the receiving portion 32, the storage device 5 at least partially extends outside the mixer 6. The support portion 31 serves as a base, that is, when the mixer 6 is placed on a support (table, working plane, etc.), the support portion defines the whole of the fixing element, whether the mixer is in use or not. The support portion 31 of the mixer 6 further includes a housing 33 and an insertion opening 34 leading to the receiving portion 32, and the storage 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 the central portion of the upper surface of the base 33 and is configured to be directed upward when the mixer 6 is disposed on a horizontal support surface (table, working plane, etc.).

[0177] The base 33 also serves as an outer housing, which has a desired design for the mixer. The base 33 may include a lower base and an upper base.

[0178] Actuation system

[0179] The mixer 6 further includes an actuating system 35, which is pivotally mounted on the support portion 31 about a substantially vertical pivot axis 36 when the mixer 6 is disposed on a horizontal support surface (table, working plane, etc.) ( Figure 6 , 8A, 8B, 8C, 9, 10A).

[0180] Preferably, the actuating system 35 performs a reciprocating motion about the pivot axis 36 along a maximum angular stroke of 45°. The motion thus consists of a maximum rotation of +45° then -45° and so on. The movement of the actuating system is along a rated stroke C35 (not shown in the figure), which is combined with the maximum angular stroke in the case of rotation about the pivot axis 36. The rated stroke C35 of the actuating system 35 is defined as the stroke between the two end positions of the actuating system 35. The intermediate position of the actuating system 35 is defined between these two end positions, and the intermediate position of the actuating system 35 corresponds to the insertion position, at which the storage device 5 can be positioned inside the receiving portion 32 of the mixer 6 without being interfered with by the actuating system 35.

[0181] The mixer 6 further includes a drive motor 39 mounted on the support portion 31. The drive motor 39 is configured such that the actuating system 35 pivots about the pivot axis 36 and within a predetermined angular range. Preferably, the drive motor 39 rotates only in a single direction.

[0182] The actuation system 35 includes a first actuation member 37 and a second actuation member 38. The first actuation member may include a first actuation finger 37.1 configured to transmit pressure to the first capsule 3. The second actuation member may include a second actuation finger 38.1 opposite the first actuation member 37 and configured to transmit pressure to the second capsule 4.

[0183] When the receiving device 5 is received in the mixer 6 and more precisely in the receiving portion 32, the first and second actuation members 37, 38 are configured to be disposed on both sides of the receiving portion 32 and thus on both sides of the receiving device 5.

[0184] The actuation members 37, 38 have at least one position in which the actuation members are at least partially inside the receiving portion 32. In an intermediate position of the actuation system 35, the actuation members 37, 38 are arranged relative to the receiving portion 32 to allow the receiving device 5 to be positioned inside the receiving portion 32 of the mixer 6; this is the insertion position.

[0185] The first and second actuation members 37, 38 are more specifically configured to apply 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 actuation members 37, 38 are configured to cooperate with the first and second pressing points 8.3, 9.3 of the first and second protective shells 8, 9 respectively or directly with the pressing elements 19, 21.

[0186] Define an actuation stroke C37 for the first actuation member 37 and an actuation stroke C38 for the second actuation member 38.

[0187] The actuation stroke C37 is defined as the stroke between the intermediate position of the first actuation member 37 in the actuation system 35 and the maximum actuation position of the first actuation member 37, in which the first actuation member 37 presses the first pressing element 19 maximally.

[0188] Conversely, the actuation stroke C38 is defined as the stroke between the intermediate position of the second actuation member 38 in the actuation system 35 and the maximum actuation position of the second actuation member 38, in which the second actuation member 38 presses the second pressing element 21 maximally.

[0189] Preferably, the movement of the actuation system 35 can be tracked by means of different sensors, especially Hall effect sensors. More precisely, each of the first actuation member 37 and the second actuation member 38 may include a magnet for interacting with a fixed Hall effect sensor. Advantageously, the Hall effect sensor can be directly provided on the control unit 45 which will be described later, as Figure 12It can be seen. Therefore, 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 possible 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.

[0190] According to the embodiment shown in FIGS. 1 to 12, the first and second actuation members 37, 38 extend substantially in the same extension plane and converge relative to the pivot axis 36.

[0191] As Figure 6 , 8A, 8B, 8C, 9 show, the actuation system 35 has a substantially annular shape defining an opening around the receiving portion 32. In the embodiment, the actuation system 35 is mainly formed by a single part, and the single part includes an opening for receiving the shaft defining the pivot axis 36.

[0192] The first actuation member 37 and the second actuation member 38 are each disposed on opposite sides of the actuation system 35. Therefore, the actuation system 35 has two faces that are pairwise opposite: the actuation members 37, 38, the opening for the pivot axis 36, and the drive mechanism with grooves to be described later.

[0193] The actuation members 37, 38 can each include drive support portions 37.3, 38.3, which are joined at the pivot axis 36 on one side. On the other side, a connecting portion 36.1 is defined, which connects the two drive support portions 37.3, 38.3. The connecting portion 36.1 can be fixed to the drive support portions 37.3, 38.3 or made of the same material.

[0194] Preferably, the two actuation members 37, 38 rotate around the same pivot axis 36. In this case, it is preferred to rotate the two drive support portions 37.3, 38.3 that are integrally connected.

[0195] However, a pivot axis can be provided for each actuation member 37, 38; however, some simple adaptations should be provided.

[0196] Alternatively, in an embodiment not shown, the actuation members move translationally.

[0197] Spring

[0198] The actuation system 35 moves along the rated stroke C35 to apply a force to the receiving device 5.

[0199] However, the clearances associated with manufacturing tolerances in the transmission chain can interfere with the transmission of force by varying the position of the actuation system 35. Thus, once the stroke is completed, there may be a few micrometers missing or, conversely, a few micrometers more. This can cause insufficient compression of the manufacturing device 2 or, conversely, damage to the manufacturing device 2.

[0200] To overcome this problem, the actuation system 35 can include springs 37.4, 38.4 (specifically visible in FIGS. 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 stroke C35 and the actuation fingers 37.1, 38.1 abut against the flat surfaces 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.

[0201] More precisely, each actuation member 37, 38 includes a spring 37.4, 38.4.

[0202] The springs 37.4, 38.4 can be located in 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.

[0203] In another embodiment, preferably because the springs are covered, the springs 37.4, 38.4 are mounted between the fingers 37.1, 38.1 and the drive supports 37.3, 38.3. Thus, since the springs are behind the base, they are not accessible to the user.

[0204] To position the springs in this location, for each actuation member 37, 38, arms 37.2, 38.2 are simply provided that are movably mounted relative to the drive supports 37.3, 38.3. The fingers 37.1, 38.1 are thus integrally mounted with the arms 37.2, 38.2.

[0205] In embodiments such as Figure 8A , 8B, 8C, 9, the arms 37.2, 38.2 are rotatably movable relative to the drive supports 37.3, 38.3 by hinges 37.5, 38.5. The springs 37.4, 38.4 are positioned between the arms 37.2, 38.2 and the drive supports 37.3, 38.3.

[0206] The springs 37.4, 38.4 thus operate in compression, meaning that the empty or non-stressed position of the spring is not compressed. The spring is compressed in the translational or rotational direction of the actuation member 37, 38.

[0207] The springs 37.4, 38.4 can be helical, leaf-type springs, or even include elastic materials or elastic assemblies (elastomers, air bubbles, etc.).

[0208] Rotary drive

[0209] According to Figure 6 , the embodiment shown in FIGS. 8A, 8B, 8C, and 9, the mixer 6 further includes a cam 41 in the form of a drive wheel or arm, which is rotatably connected to the output shaft 39.1 of the drive motor 39 and is configured to be rotationally driven about the rotational axis 41.1 of the cam. The cam 41 is mounted on the support portion 31. In order to permit a reciprocating motion with a large lever arm, preferably, the pivot shaft 36 and the cam 41 are on both sides of the receiving portion 32.

[0210] The cam 41 is provided with a drive finger 42 that is eccentric with respect to the rotational axis 41.1 of the cam.

[0211] The cam 41 is typically driven by the drive motor 39 by means of one or more belts. In this case, starting from the drive motor 39 and the output shaft 39.1 equipped with a pulley, the transmission chain is as follows: belt 39.2, pulley 39.3 connected to the pulley 39.4 by a shaft, belt 39.5, cam 41.

[0212] The drive finger 42 is received in a drive groove 43 provided in the actuating system 35. Specifically, the drive groove 43 is formed in the connecting portion 36.1. The drive groove 43 is elongated and extends along a direction substantially parallel to the extension direction of the pivot shaft 36. This configuration of the mixer 6 allows a reciprocating motion of the actuating system 35 to be obtained while causing the drive motor 39 to always rotate in the same rotational direction, such that an expensive control system for the drive motor 39 is not required.

[0213] The drive groove 43 extends along its depth towards the pivot shaft 36.

[0214] Now the connection between the drive groove 43 and the drive finger 42 will be described. Given the situation where the actuating system 35 rotates, the alignment of the drive groove 43 and the drive finger 42 is variable, which means that a simple adjustment will jam the system. Conversely, the presence of a clearance that causes misalignment generates noise and delays the end of each stroke.

[0215] To solve this problem, a ball-and-socket joint is provided between the drive finger 42 and the drive groove 43, which allows the above-mentioned misalignment to occur.

[0216] Specifically, the ball 42.1 is mounted on the drive finger 42, and the ball is received in the ring 43.1. The connection between the ball 42.1 and the ring 43.1 is a ball-and-socket joint. The ring 43.1 itself is received in the drive groove 43, and the ring is translationally movably mounted in the drive groove along a direction parallel to the pivot axis 36 (thus along the length of the drive groove 43). Finally, the ball 42.1 is translationally movably mounted along the drive finger 42. The arrangement of these different connections can be different, meaning that the ring can also be translationally movable along the depth of the groove and the ball is thus fixed to the drive finger.

[0217] Therefore, the complete connection between the drive finger 42 and the actuation system 35 sequentially includes a guide rail, a ball-and-socket joint, and a guide rail perpendicular to the other guide rail. Therefore, in the movement torque, it is noted that the force is transmitted only on one of the six torque components, that is, the translational component tangent to the rotational movement of the actuation system 35, that is, the component that allows the actuation system 35 to rotate. The kinematic equivalent is a ball-spherical connection (also called a point connection).

[0218] In order for the above connection not to be more complex and useless, the rotational axis 41.1 of the cam and the pivot axis 36 are preferably orthogonal. This allows for a drive finger 42 that performs a circular motion in a plane parallel to the pivot axis 36.

[0219] The movement of some settings of the connection can be simply achieved by a plastic slide rail / plastic, and the wear of the plastic slide rail is slow enough to ensure a satisfactory service life.

[0220] According to an implementation variant of the present invention, the mixer 6 can be configured such that the rotation of the drive motor 39 in the first rotation direction drives the actuation part 35 to pivot in the first pivot direction, and the rotation of the drive motor 39 in the second rotation direction opposite to the first rotation direction drives the actuation part 35 to pivot in the second pivot direction opposite to the first pivot direction.

[0221] Eccentricity of the pivot shaft

[0222] The actuating members 37, 38 each move along the actuating strokes C37, C38.

[0223] However, in the embodiment shown in the figure, one of the two actuating members 37, 38 has an actuating stroke C37, C38, and the length of this actuating stroke is strictly greater than the length of the actuating stroke of the other actuating member. This difference in the actuating strokes C37, C38 allows for better mechanical and electrical management of the force 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 required on the side of the thickest capsule, and the pressing element 19 will contact and operate more quickly than the pressing element 21.

[0224] To achieve this difference in stroke, several solutions can be considered. One solution consists in having a drive groove 43 that is not centered in the connection part 36.1.

[0225] In particular Figure 8A , another solution as shown in 8B, 8C, 9 aims to make the pivot axis 36 eccentric. On the other hand, the rotational axis 41.1 of the cam does not intersect the pivot axis 36. When the cam 41 makes a complete rotation, this results in a difference in stroke between the two actuating members 37, 38. The distance (orthogonal, i.e., by orthogonal projection) between the rotational axis 41.1 of the cam and the pivot axis 36 being 1% to 5% of the distance between the drive groove 43 and the pivot axis 36 is sufficient and does not much affect the overall symmetrical appearance. In absolute terms, a distance between 1 mm and 2 mm is suitable.

[0226] The eccentricity can also be defined by means of the receiving part 32 relative to the rotational axis of the cam 41: thus the end position of the actuating system 35 is not centered around the receiving part 32.

[0227] The eccentricity can also be defined relative to the first and second mounting surfaces 11.1, 12.1 or relative to the position of the first and second capsules 3, 4 in the receiving part 32: by means of the flat surfaces 3.7, 4.7, which thus define a virtual surface in the receiving part 32. The maximum distance of the first actuating member 37 to the surface of the flat surface 3.7 is greater than the maximum distance of the second actuating member 38 relative to the flat surface 4.7.

[0228] For this purpose, in a variant, the pivot axis 36 is contained in a plane equidistant from the two mounting surfaces 11.1, 12.1.

[0229] Under the effect of the eccentricity, the first actuating finger 37.1 is advantageously longer than the second actuating finger 38.1. This is especially due to the fact that, due to the eccentricity, the end positions of the compensating actuating fingers 37.1, 38.1 are compensated. More precisely, the actuating fingers 37.1, 38.1 working on the thicker first or second capsule 3, 4 have a greater length than the other actuating finger 37.1, 38.1.

[0230] Figure 8AAnother solution shown aims not to define an intermediate position of the actuation system 35 at the high or low dead points of the cam 41. In fact, by choosing the intermediate position of the actuation system 35 at a non-zero angle Ag (typically between 5° and 30°) relative to the 12 o'clock direction (when the mixer 6 is placed on the horizontal support), the distribution of the actuation strokes C37, C38 is staggered. Also, it should be noted that for an angle Ag' = 180° - Ag, another intermediate position is thus obtained.

[0231] In fact, the actuation strokes C37, C38 at the cam 41 correspond to a rotation from said angle Ag to the nearest 90° (i.e., the 3 o'clock direction or the 9 o'clock direction, when the mixer 6 is placed on the horizontal support), and then to a rotation from said angle Ag' to 270°. Since Ag and Ag' are not at 0° and 180° (the 12 o'clock direction and the 6 o'clock direction), it is immediately noted that the strokes C37 and C38 are not equal. Regarding a complete rotation of the cam 41, thus in the first direction, the first actuation stroke C37 is passed, then in the second direction, the first actuation stroke C37 is passed, then in the first direction, the second actuation stroke C38 is passed, and then in the second direction, the second actuation stroke C38 is passed, i.e., two rated strokes C35.

[0232] Contact track of the mixer

[0233] As mentioned above, the mixer 6 itself further includes electrical contact tracks 31.11, 31.12 and electrical contact tracks 31.51, 31.52, which are 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 the electrical contact tracks 31.51, 31.52 are configured to engage with the supplementary electrical contact tracks 46.51, 46.52 of the longitudinal grooves 23.2, 24.2.

[0234] These electrical contact tracks are mounted on guide rails 31.1, 31.2 ( Figure 1A , 7A), which are integral with the support 31 and mounted on two connecting sides of the receiving portion 32. The positions of the electrical contact tracks 31.11, 31.12 (and 31.51, 31.52) on the guide rails 31.1, 31.2 are complementary to the positions of the electrical contact tracks 23.1, 24.1 (and 46.5, 46.52) of the connecting surfaces 23, 24 of the receiving device 5. The guide rails 31.1, 31.2 help to define the receiving portion 32. The guide rails are located, for example, at the edges and are preferably fixed to the support 31 over their entire length.

[0235] The positions of the electrical contact tracks 31.51, 46.51, and 31.52, 46.52 on the two opposite and spaced-apart guide rails 31.1, 31.2 have the advantage that once the liquid flows by gravity onto one of the guide rails 31.1, 31.2, the risk of short circuit is restricted.

[0236] Blocking mechanism, connecting mechanism, taking-out mechanism

[0237] The mixer 6 further includes a holding mechanism 50, a connecting mechanism 52, and a clamping mechanism 54( Figure 10A , 10B, 10C, 10D, 10E, 10F, 11A, 11B, 11C).

[0238] Each of these mechanisms has its own and independent function. However, these mechanisms can advantageously be driven simultaneously by the same auxiliary motor 40.

[0239] The function of the holding mechanism 50 is to prevent the removal of the receiving device 5 during stirring.

[0240] The holding mechanism 50 is movably mounted relative to the support portion 31 between an insertion position and a holding position. 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 prevents the insertion of the receiving device).

[0241] The holding mechanism 50 includes a movable element 50.1 that moves between the above two positions, and the movable element extends in the receiving portion 32 in the holding position. Specifically, in the holding position, the movable element 50.1 cooperates with the holding stop 9.6 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 holding stop 9.6 abuts against the movable element 50.1 and gets stuck). For this purpose, when the receiving device 5 is placed in the mixer, the movable element 50.1 and the holding stop 9.6 are arranged to be located near the holding position, preferably less than 2 mm.

[0242] In Figure 10A , 10B, 10C shown in the embodiment, the movable element 50.1 is a wheel, that is, a holding wheel, which moves around the wheel rotation axis 50.2. The wheel 50.1 has at least two different radii, the smaller radius is configured not to extend into the receiving portion 32 in the insertion position, and the larger radius is configured to extend into the receiving portion 32 in the holding position so as to contact and abut against the holding stop 9.6 in the case of removal.

[0243] The wheel 50.1 is preferably circular with a flat portion that allows the insertion position.

[0244] The wheel 50.1 is mounted on a shaft extending along the wheel rotation axis 50.2. The shaft includes a gear 51 or a pulley, which is connected to at least one other gear or another pulley 51.1.

[0245] Alternatively, the movable element 50.1 is translationally movable, for example, by means of a rack and pinion system via the gear 51.

[0246] The function of the connecting 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 held in nested engagement through their connection joints 3.4, 4.4.

[0247] The connecting mechanism 52 is movably mounted relative to the support 31 between an insertion position and a connection position. In the insertion position, the connecting structure 52 allows the insertion and removal of the receiving device 5. In the connection position, the connecting mechanism 52 locks the first and second capsules 3, 4.

[0248] The connecting mechanism 52 includes a connecting element 52.1 that is movable between the above two positions, and the connecting element extends in the receiving portion 32 in the connection position. Specifically, in the connection position, the connecting element 52.1 cooperates with the connection button 9.8, which moves inside the second receiving position 14. For this purpose, when the receiving device 5 is installed in the mixer 6, the connecting element 52.1 and the connection button 9.8 are opposite to each other.

[0249] In Figure 10A , 10B, 10C of the illustrated embodiment, the connecting element 52.1 is a wheel, i.e., a connecting wheel, which is movable about the wheel rotation axis 52.2, and the wheel rotation axis preferably coincides with the wheel rotation axis 50.2. The wheel 52.1 has at least two different radii, with the smaller radius configured not to extend into the receiving portion 32 in the insertion position, and the larger radius configured to extend into the receiving portion 32 in the connection position in order to contact and press the connection button 9.8.

[0250] The wheel 52.1 preferably has an elliptical shape in a plane.

[0251] The wheel 52.1 is mounted on a shaft extending along the wheel rotation axis 52.2. The shaft includes a gear or a pulley, which is connected to at least one other gear or another pulley 51.1. The shaft and the gear are preferably the same as the shaft and the gear 51. Thus, a first sub-assembly with a rotational connection is obtained.

[0252] Alternatively, the connecting element 52.1 is translationally movable, for example, by means of a rack and pinion system via the gear 51.

[0253] The connecting mechanism 52 is different from the actuation system 35. This is caused by different positions (e.g., different heights) in the mixer 6. Similarly, the receiving device 5 includes pressing points 8.3, 9.3 that are different from the connecting button 9.8.

[0254] The function of the clamping mechanism 54 is to clamp the output channel 3.5 of the first capsule 3 during the mixing process. In fact, the pressure inside the first or second capsule 3, 4 can cause an unwanted output of the cream. In this case, the cream spreads in the mixer 6, which is to be prohibited. This is shown in Figure 11A , 11B, 11C.

[0255] 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 the insertion and removal of the receiving device 5 that carries the first capsule 3. In the clamping position, the clamping mechanism 54 clamps the output channel 3.5.

[0256] The clamping mechanism 54 includes a clamping wheel 54.1 that rotates movably about a clamping wheel axis 54.2.

[0257] The mixer 6 also includes a fixed guide wall 54.3 (integrated with the support 31 and even made of the same material as the support) and a clamping wall against which the clamping wheel 54.1 rolls or slides, and the clamping wheel is clamped in the clamping position against this clamping wall. The clamping wall is advantageously part of the guide wall 54.3. Multiple variants are distinguished: one variant in which the clamping wheel 54.1 approaches the guide wall 54.3 towards the clamping position, one variant in which the distance is constant or variable, and in which the clamping wall has a special recess to capture the clamping wheel 54.1 (which is possible due to the translatory movement of the clamping wheel 54.1, as can be seen below).

[0258] The teeth 54.11 present on the clamping wheel 54.1 (in practice, the wheel includes a circular or substantially circular part that clamps the first capsule 3 and a toothed part that is preferably below the circular part) can engage in the teeth 54.31 in the guide wall 54.3 such that the clamping wheel 54.1 rolls against the guide wall 54.3. Furthermore, due to the teeth 54.11, 54.31, the clamping wheel 54.1 has a rolling motion against the clamping wall 54.3 without a sliding motion, which allows avoiding the dangerous sliding that would result in a poor clamping of the output channel 3.5. Finally, due to the teeth 54.11, 54.31, the distance (except for the teeth, i.e., the average distance) between the clamping wheel 54.1 and the guide wall 54.3 can be reduced to almost zero below the first capsule 3 while maintaining the rolling motion against the guide wall 54.3.

[0259] To permit this transmission, the clamping wheel 54.1 is mounted on the arm 54.5 and preferably mounted rotatably movably, and the arm itself is rotatably movable about the arm rotation axis 54.51.

[0260] The arm 54.5 is integral with a gear (or pulley) or gear part 54.52 which is itself connected to the common gear 40.1 by various gears or pulleys. Thus, the arm 54.5 is rotationally driven by the same auxiliary motor 40.

[0261] To ensure clamping in the clamping position, including when the auxiliary motor 40 is no longer energized, the clamping wheel 54.1 is mounted radially translatably movably along the arm 54.5. A restoring mechanism 54.4 provided 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 press the clamping wheel 54.1 against the guide wall 54.3. More precisely, an intermediate support portion including the rotation axis 54.2 of the clamping wheel 54.1 is provided. This support portion is translatably movable relative to the shaft 54.5. In the intermediate support portion, the sliding connection with the pin 54.42 sliding in the groove 54.53 of the shaft 54.5 allows guided translation and also advantageously allows limiting the translational movement.

[0262] The restoring mechanism 54.4 thus works in compression, where, by default, the restoring mechanism is not compressed (or is rarely compressed). A helical spring, leaf spring or other type of spring may be suitable.

[0263] Due to the restoring mechanism 54.4, the clamping wheel 54.1 can remain pressed 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 can gradually decrease towards the region where the output channel 3.5 is located).

[0264] Common drive

[0265] Preferably, the holding mechanism 50, the connecting mechanism 52 and the clamping mechanism 54 are simultaneously driven by a common drive, as described according to the following embodiments. The holding mechanism 50 is driven by a gear 51 which is at least connected to another gear 51.1 ( Figure 10A , 10B).

[0266] The connecting mechanism 52 is driven by a gear which is at least connected to another gear, preferably the gear 51 and another gear 51.1 ( Figure 10A , 10B).

[0267] The clamping mechanism 54 is driven by the gear part 54.52.

[0268] Different drive chains can be provided, and a common gear 40.1 is preferably provided, which then drives another gear 51.1 and a gear section 54.52.

[0269] As Figure 11A , as shown in 11B, 11C, the common gear 40.1 is located on the output shaft of the auxiliary motor 40. The common gear meshes directly with the gear 51.1, which is mounted on a shaft including another gear 51.2. This gear 51.2 itself meshes with the gear section 54.52. Thus, there is a very simple drive chain, which has a minimal amount of gears and thus has minimal frictional losses, has a minimal risk of damage, and has very small clearances.

[0270] Due to the 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 connecting position or the clamping position. The same auxiliary motor 40 thus drives three mechanisms, which constitutes a major simplification of the mixer 6 and its operating principle.

[0271] Visual and sound display

[0272] The mixer 6 advantageously includes a screen 60 and / or a loudspeaker (Figs. 1A, 1B, 7) that allows for the exchange of information with the user.

[0273] The screen 60 is preferably touch-sensitive in order to avoid the setting of physical buttons. The screen allows the user to indicate the start of the cycle and the moment of removal. The screen 60 can also display the end of the cycle, for example, accompanied by an audible reminder.

[0274] Power supply and control unit

[0275] According to an embodiment of the invention, the mixer 6 further includes a power supply (not shown in the figures), 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 even uniquely includes at least one rechargeable battery 44 ( Figure 7B ). In the example shown, the rechargeable battery 44 advantageously consists of a lithium-ion battery having two battery cells, which provides a rated output voltage of 7.4V.

[0276] As Figure 12As shown, the mixer 6 further includes a control unit 45, which for example includes a controller such as a microcontroller or a processor 45.1, and this controller is configured to control the operation of the manufacturing device 2, and more specifically to control the operation of the drive motor 39, the auxiliary motor 40, the heating element 46, the temperature sensor and the screen 60 (for the screen, preferably the processor), as well as all sound or visual devices. The control unit 45 advantageously includes a non-volatile type of memory 45.2, which stores instruction lines in the form of a program to be executed by the controller or the processor 45.1, in particular in order to implement some of the steps described in the following methods.

[0277] Other embodiments

[0278] In a variant, the holding device 5 is integrated with the mixer 6. Therefore, it is only necessary to insert the first or second capsule 3, 4 into the first or second receiving positions 13, 14. The receiving portion 32 is still defined, and this receiving portion corresponds to the space occupied by the receiving device 5.

[0279] Furthermore, in this variant, the actuating surfaces 8.1, 9.1 may be absent: in this case, the actuating members 37, 38 press directly on the first or second capsule 3, 4.

[0280] Usage method

[0281] Now, at least one manufacturing method for manufacturing a composition such as a beauty product by means of the manufacturing device 2 will be described. This manufacturing method is broken down into a plurality of sub-methods (for the sake of clarity, called "methods"), and one or more variants of this 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.

[0282] Specifically, these methods (or their variants) are advantageously implemented by means of different embodiments of the above-mentioned manufacturing device 2. Preferably, most of the steps of the methods Ei, Em and Er are stored in the non-volatile type of memory 45.2 in the form of code line instructions that can be executed by the processor 45.1.

[0283] The preparatory method Ep includes a preparatory step Ep1 for preparing the entire use of the manufacturing device 2, and this preparatory step is intended to connect the manufacturing device to the power grid or charge the battery 44. In addition, this preparatory step Ep1 can be before or after the step Ep2 of placing the manufacturing device 2 on a flat support, and if necessary, it can have a power-on step.

[0284] Then the initial method Ei is implemented. In step Ei1 (“receiving step”), the processor of the manufacturing device 2 receives a start command. This start command is typically generated by the user's action (contact with the touch screen 60, button, switch, etc.).

[0285] After this step Ei1, in step Ei2 (“checking step”), the method ensures that the actuation system 35 is in an intermediate position that allows the insertion of the receiving device 5 or the first and second capsules 3, 4. Typically, it should be ensured that the receiving portion 32 (for the insertion of the receiving device 5) or the first or second receiving positions 13, 14 (for the insertion of the first or second capsule 3, 4 without the receiving device 5) are not blocked by the actuation system 35. During this step Ei2, it is also appropriate to check that the clamping mechanism 54, the connecting mechanism 52, and the holding mechanism 50 are not activated, i.e., in their respective insertion positions.

[0286] After this step Ei2, in the receiving portion 32, the receiving device 5 including the first or second capsule 3, 4 can be manually inserted, or even the first or second capsule 3, 4 can be directly inserted.

[0287] Finally, in the subsequent step Ei3 (“closing step”), at least one of the clamping mechanism 54, the connecting mechanism 52, and the holding mechanism 50 is activated, i.e., they move. This step Ei3 includes, for example, the processor sending a command to the auxiliary motor 40 to start the auxiliary motor so that, in the case where the above three mechanisms are all connected to a common gear (or pulley) 40.1, the auxiliary motor drives these three mechanisms. The auxiliary motor 40 moves from a first position to a second position so that the clamping mechanism 52, the connecting mechanism 54, and the holding mechanism 50 move from their respective insertion positions to their respective clamping, connecting, and holding 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.

[0288] Steps Ei1, Ei2, Ei3 are particularly executed by the processor 45.1.

[0289] After this initial method Ei, the mixer 6 is ready to start working on the first and second capsules 3, 4: this is the purpose of the mixing method Em and the removal method Er.

[0290] The mixing method Em includes a first step Em1 in the preparation stage (“initial step of moving the actuation system”). During this first step, the connecting solder of the capsule positioned farther from the heating element 46 (the second capsule 4 in the figure) is broken, and the capsule is compressed so that part of the content of the capsule is sent towards the capsule closer to the heating element 46. According to the given embodiment, the second actuating member 38 moves to break the connecting solder in the second capsule 4 (the second capsule includes, for example, a preparation of the oil phase). Thus, part of the content of the second capsule 4 is sent towards one side of the first capsule 3, especially into the connecting channel 3.3 (because the connecting solder of the first capsule 3 has not been broken yet). The second actuating member 38 preferably moves along its actuating stroke C38. For reasons of design simplicity, a partial stroke sensor for the second actuating member 38 is not required.

[0291] In the step Em2 of the preparation stage (“second step of moving the actuation system” or “prestress step”), the first actuating member 37 moves along a partial stroke strictly less than its actuating stroke C37 and holds its position to apply a prestress on the first capsule 3 (which includes, for example, a preparation of the aqueous phase) so that the flat surface 3.7 presses against the diffusion plate 46.2. This prestress allows for better heat exchange between the diffusion plate 46.2 and the first capsule 3 during the subsequent step Em3 (“heating step”). It should be noted that due to the movement of the first actuating member 37 along the partial stroke, the pressing of the first capsule 3 against the diffusion plate 46.2 is carried out without causing the breaking of the connecting solder in the first capsule 3 (which would cause the preparation in the first capsule 3 to be sent towards the second capsule 4).

[0292] In the step Em3 of the preparation stage (“heating step”), the heating element 46 is activated to generate heat towards the first capsule 3. Since the heating element 46 is positioned on the side of the flat surface 3.7 of the first capsule 3 and the prestress step has allowed for good thermal contact between the diffusion 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 thus activated in the absence of the entire movement of the actuating members 37, 38.

[0293] During the step Em3 of the preparation stage, the temperature of the heating element 46 reaches a target temperature Tc between 80°C and 90°C. The purpose of this target temperature Tc is to bring the content of the first capsule 3 to a target temperature Tc' that is also between 80°C and 90°C and preferably about 85°C. In fact, it is observed that during this heating step Em3, the temperature of the content of the first capsule 3 roughly corresponds to the target temperature Tc of the heating element 46, but with a slight time difference.

[0294] Then, in step Em3’ (“mixing step”) of the stirring phase, the heating element 46 is deactivated and then the first actuating member 37 moves along its rated stroke in order to break the connecting solder in the first capsule 3. The interruption of the power supply to the heating element 46 before activating the first actuating member 37 allows the integrity of the power provided by the power supply, which can be used to power the drive motor 39. This feature is particularly advantageous when the mixer 6 is powered by a low-power power converter or battery 44. In fact, this feature allows to avoid that the power supplied to the drive motor 39 is insufficient to allow the breaking of the connecting solder of the first capsule 3 (which causes jamming of the device), this breaking step of the connecting solder requiring a large motor torque. When the first actuating member 37 reaches the end of its actuating stroke C37, the content of the first capsule 3 is sent into the second capsule 4, and the two preparations can thus freely circulate from the first or second capsule 3, 4 towards the second or first capsule 4, 3 via the connecting parts 3.2, 4.2 during each reciprocating movement of the actuating system 35, the connecting solder originally present in each of the first and second capsules 3, 4 having been broken.

[0295] Subsequently, steps Em4, Em5, Em6 are successive steps of stirring, with or without heating (referred to as the stirring phase).

[0296] Step Em4 (“stirring step without heating”) of the stirring phase is intended to make the actuating members 37, 38 perform reciprocating movements without activating the heating element 46, i.e. without heating. During this step, the first and second capsules 3, 4 each deform at least once. According to an embodiment, step Em4 lasts at least 1.4 s and preferably between 2 s and 4 s. This stirring step without heating allows to start the drive motor 39 at a constant speed while favoring the entire power of the power supply.

[0297] Steps Em1, Em2 and Em3, Em3’, Em4 alternate the movement of the actuating system 35 and the heating by the heating element 46. This is specifically caused by the power supply dedicated to the actuating system 35 or the heating element 46. This unique alternation allows to protect the battery 44 by distributing the high-power moments. In fact, the start of the movement causes a large resistance torque, which requires a large motor torque, and the temperature rise also requires a large power: the battery 44 is thus strongly demanded. This alternative solution also allows to reduce the size of the components, which is inherent in the manufacture of the mixer and in the design limitations on the battery.

[0298] Conversely, once the temperature is near the target temperature Tc’ and once the actuating system 35 has moved, the demand on the battery 44 is reduced and it is allowed to supply power to the heating element 46 and the actuating system 35 in parallel: this is the purpose of step Em5.

[0299] During step Em5 of the agitation phase (“agitation step with heating”), the actuation system 35 remains activated and the heating element 46 is activated in order to keep the preparation mixed at a temperature which is preferably the target temperature Tc’. Thus, the heating element is maintained at the target temperature Tc. This step Em5 lasts for example between 5 seconds and 30 seconds and preferably between 7 seconds and 15 seconds. Although the battery 44 is less demanded than for starting or for temperature rise, the battery may tend to discharge rapidly during this phase with limited duration.

[0300] However, in order for the first and second capsules 3, 4 to each deform several times and for the emulsion obtained from the preparation mixture to be satisfactory, this step Em5 is long enough.

[0301] Between steps Em4 and Em5, the actuation system 35 is not stopped.

[0302] Subsequently, step Em6 of the agitation phase (“cooling step with agitation”) is implemented. Alternatively, this step can be achieved without agitation, but preferably the actuation system 35 remains activated in order to improve or maintain the homogenization of the preparation. During step Em6, the temperature of the cream decreases to the withdrawal temperature Tr’ which is between 35 °C and 48 °C and preferably between 38 °C and 42 °C. In the case of the illustrated embodiment, 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. During the cooling step, this temperature difference between the contents of the first and second capsules 3, 4 and the temperature of the heating element 46 is especially explained by the fact that during agitation, the composition is present only for a part of the time in the first capsule 3 and thus is opposite the diffusion plate 46.2 only for a part of the time, while the temperature measurement is performed at this diffusion plate.

[0303] The simplest technique for cooling is to stop the power supply to the heating element 46 and to cool the cream by air at ambient temperature. Thus, the duration of step Em6 actually depends on the ambient temperature. For this purpose, the temperature sensor is advantageously positioned in the mixer 6 and more precisely in the receiving device 5. In order to limit the number of temperature sensors, the same sensor measures the temperature of the heating element 46.

[0304] As in the illustrated embodiment, the temperature sensor measures the temperature of the heating element 46 and the same sensor is reused: this means that the end of step Em6 is determined by the temperature measured by said sensor, i.e. by the withdrawal temperature Tr’ which is between 55 °C and 60 °C.

[0305] Once the withdrawal temperature is reached, the actuation system 35 is stopped.

[0306] The cooling step Em6 typically lasts at least 20 seconds and preferably 40 seconds.

[0307] In an implementation variant, step Em6 may also advantageously include, for example, a minimum stirring duration of about 40 seconds, followed by a supplementary stirring duration, the minimum stirring duration allowing good emulsification to be ensured, the supplementary stirring duration intervening only if the withdrawal temperature Tr’ has not been reached. On the other hand, even if the temperature is less than the withdrawal temperature Tr’, stirring continues for a certain duration.

[0308] 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 efficient manner and accelerating the process. For example, a cooling system equipped with a small-sized fan may be provided, with or without supplementary cooling elements, the fan forcing air to circulate in the mixer 6 and thus forcing cooling by forced convection.

[0309] Once the mixing method Em has ended, the withdrawal method Er can be initiated. The withdrawal method Er will now be described.

[0310] Since the above steps take a certain amount of time (usually more than one minute), the user may not be next to the mixer 6 but be busy with their daily tasks (having 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.

[0311] To this end, in step Er1 (“transfer step for storage”), the actuation system 35 is activated once to transfer the cream into a capsule (i.e., here the first capsule 3) located on the side of the heating element 45. This step is non-compulsory once step Em6 has been stopped in a good configuration.

[0312] In step Er2 (“prestress maintenance step”), the actuation system 35 returns to the prestress position, in which the first actuation member 37 exerts a prestress on the first capsule 3 so as to bring the first capsule into contact with the diffusion plate 46.2. Then, in step Er3 (“thermal insulation step”), the heating element 46 is activated to keep the cream at the withdrawal temperature Tr’. The 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 to ensure good emulsification, which may be partially damaged by the presence of hot spots on the diffusion plate 46.2.

[0313] In the case of implementing the variant example, the extraction method may include, instead of step Er2, step Er2' ("holding step in the intermediate position"), in which the actuation system 35 is activated to be placed in the intermediate position, i.e., without forcing the first or second capsule 3, 4 and specifically without forcing the first capsule 3 against the heating element 46. Surprisingly, this variant example allows for better emulsification to be maintained and avoids the use of periodic stirring during the insulation phase.

[0314] Step Er3 is implemented during a predetermined waiting duration. This duration is less than 15 minutes so as not to supply power to the heating element 46 for too long, and this duration is greater than 1 minute and preferably about 5 minutes so as to allow flexibility for the user in the morning time management.

[0315] On the other hand, this means that after the movement of the actuation system 35 ends, the user has a time between 1 minute and 15 minutes and preferably about 5 minutes (selected according to factory parameters or user parameters) to restore the cream to a good temperature.

[0316] As soon as the user is ready to use the cream, the user touches the touch screen or presses a button, which starts step Er4 ("step of receiving the extraction instruction"), during which the mixer 6 receives the extraction command.

[0317] Then, in step Er5 ("step of placing in the intermediate position"), the actuation system 35 is activated to be placed in the intermediate position.

[0318] In the case where the actuation system 35 is pre-stressed at the first actuation member 37, this first actuation member should end its movement, which moves the preparation to the second capsule 4, and then the actuation system 35 stops at the intermediate position, which corresponds to a position suitable for extracting the receiving device 5. This position also corresponds to the starting position suitable for implementing the next manufacturing cycle of the above-described 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.

[0319] In the case of implementing the variant example, the actuation system 35 is already in the intermediate position at step Er2', for the insulation of step Er3. It may be necessary for the actuation system 35 to perform a reciprocating movement in order to be positioned in the intermediate position suitable for implementing the next manufacturing cycle of the above-described method, i.e., the second actuation member 38 is ready to compress the second capsule 4 at step Em1.

[0320] During this reciprocating movement of the actuation system 35, the cream present in the first capsule 3 is partially sent into the second capsule.

[0321] Finally, in the last step Er6 (unlocking step), each mechanism activated in step Ei3 is placed in the insertion position. Similarly, this step Er6 means the activation of the auxiliary motor 40.

[0322] Subsequently, the user grasps the receiving device 5 and removes the receiving device from its receiving portion 32. Then, the user presses the actuation surfaces 8.1, 9.1 to pivot the blades so as to drive out the cream present in the first and second capsules 3, 4 through the output channel 3.5 of the first capsule 3. Finally, it is necessary 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 (manufacturing device 2 or receiving device) comes into contact with the preparation.

[0324] Ei1: The receiving step of receiving the start command (implemented by the mixer and more precisely by the processor);
