Description

Technical Field

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

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

[0003] - a first capsule comprising a first compartment and a first connection portion, the first compartment containing a predetermined amount of a first agent,

[0004] - a second capsule comprising a second compartment containing a predetermined amount of a second agent and a second connection portion configured to be connected to the first connection portion, and

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

[0006] The mixer comprises in particular:

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

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

[0009] - a drive motor mechanically coupled to the first and second pressing elements and configured to enable cyclic movement of the first and second pressing elements between an inactive position and an active position.Such a manufacturing device allows the end consumer to manufacture personalized beauty products using different capsules.

[0010] 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 first and second deformable compartments suitable for ensuring the migration of the contents from the first compartment toward the second compartment and conversely the migration of the contents from the second compartment toward the first compartment, and in particular when the first and second deformable compartments or the connecting channels associated with the first and second deformable compartments are closed by a weak connection area.

[0011] Providing a large-sized drive motor significantly increases the manufacturing cost of the manufacturing equipment as well as its volume and weight.

[0012] Furthermore, the mixing of capsules is more complex than expected and requires improvements in both the materials and the way they are used. Summary of the invention

[0013] The present invention aims to overcome all or part of these disadvantages.

[0014] The technical problem underlying the present invention therefore consists in providing a device for manufacturing a composition which is simple, compact and easy to use, while having a simple structure and a reduced price.

[0015] In particular, in the process of preparing a composition by mixing two formulations, the management of preparation time, heating and stirring is complicated, especially because of the brittleness of the formulations. In addition, it is important to know when to end the mixing process.

[0016] In this regard, the invention proposes a mixing method in a manufacturing device comprising a mixer comprising a support defining a receiving housing comprising a first receiving position configured to receive a first deformable capsule and a second receiving position configured to receive a second deformable capsule, the first capsule and the second capsule being intended to be fluidically coupled to each other and to contain a first preparation and a second preparation, respectively,

[0017] The manufacturing apparatus includes an actuation system configured to transmit pressure to the first capsule and the second capsule to move the contents of the first capsule in the second capsule, and vice versa,

[0018] The mixer includes a heater element configured to heat at least one of the first capsule and the second capsule when the first capsule and the second capsule are received in the mixer,

[0019] The method comprises the following steps:

[0020] - a heating step (Em3) and / or a stirring step (Em4, Em5) comprising, alternately or simultaneously, setting the movement of the actuation system and heating to a target temperature (Tc) by means of a heater element, and then

[0021] - A stirring cooling step (Em6) performed by setting the movement of the actuation system, cooling to the take-out temperature (Tr) at which stirring stops.

[0022] In one embodiment, the cooling step (Em6) is performed for a predetermined period of time, such as at least 20 s, preferably at least 30 s.

[0023] In one embodiment, the removal temperature (Tr) corresponds to a temperature of the heater element between 55°C and 60°C, or a temperature of the contents of the first and / or second capsules between 35°C and 50°C, preferably between 38°C and 42°C.

[0024] In one embodiment, the target temperature (Tc) is at least 20° C. greater than the removal temperature (Tr).

[0025] In one embodiment, the heating step (Em3) and / or the stirring step (Em4, Em5) continuously comprises:

[0026] - a heating step (Em3),

[0027] - Heating and stirring step (Em5) using the actuation system to maintain the temperature at the target temperature (Tc).

[0028] In one embodiment, the stirring step (Em4, Em5, Em6) includes a non-heating stirring step (Em4) by means of an actuation system between the heating step (Em3) and the heating stirring step (Em5).

[0029] In one embodiment, a manufacturing apparatus includes a receiving device configured to receive a first capsule and a second capsule.

[0030] In one embodiment, the cooling step (Em6) is followed by at least one removal method step (Er), during which the actuation system can be actuated to enter the neutral position.

[0031] The invention also proposes a manufacturing device for manufacturing a composition, the manufacturing device comprising a mixer, the mixer comprising a support defining a receiving housing, the receiving housing comprising a first receiving position configured to receive a first deformable capsule and a second receiving position configured to receive a second deformable capsule, the first capsule and the second capsule being intended to be fluidically connected to each other and containing a first preparation and a second preparation, respectively,

[0032] The mixer comprises at least one actuation system configured to transmit pressure to the first capsule and the second capsule to move the contents of the first capsule in the second capsule, and vice versa,

[0033] The manufacturing apparatus includes a heater element configured to heat at least one of the first capsule and the second capsule when the first capsule and the second capsule are received in the mixer,

[0034] Characterized in that the manufacturing equipment is configured to implement the hybrid method as described above.

[0063] Figure 1A and 1B A manufacturing device 2 according to a first embodiment of the invention is shown, which is configured to manufacture a composition, which may be, for example, a cosmetic product, a hair care product, a medicinal product, a sterilizing product, a maintenance product, a cleaning product or an agricultural product. When the composition to be prepared is a cosmetic product, the latter may be, for example, a homogeneous emulsion, a homogeneous solution or a mixture of several miscible phases.

[0064] The manufacturing device 2 is mainly intended for personal and small-scale use: it allows the preparation of a single part for use. Therefore, its size must meet the size restrictions in bathrooms, beauty salons, luggage (for transportation), etc. Therefore, the size of the manufacturing device 2 is not greater than 40 cm.

[0065] The manufacturing device 2 includes a receiving device and a mixer 6, wherein the receiving device is configured to receive first and second capsules 3, 4, also referred to as independent packages or packaging units, which contain a predetermined amount of a first preparation and a predetermined amount of a second preparation, respectively, and the mixer is configured to mix the first and second preparations contained in the first and second capsules 3, 4 received in the manufacturing device 2 to obtain a cosmetic product.

[0066] The mixer 6 comprises a receiving housing forming part of the receiving means, which is arranged to receive the first and second capsules 3 , 4 directly or via specific receiving means 5 .

[0067] In a preferred embodiment, and Figure 1A , 1B , 7A, 8A, 8B, 8C, the mixer 6 comprises a receiving housing 32 capable of removably receiving the receiving device 5. In this case, the receiving housing 32 has a shape that is substantially complementary to the shape of the receiving device 5.

[0068] The mixer 6 also comprises an actuation system 35 configured to exert a force on the first capsule 3 and the second capsule 4 , if necessary via the receiving device 5 , so as to allow mixing and stirring of the composition to be manufactured.

[0069] The receiving device 5, also called a reciprocating member (because it serves as a carrier for the first and second capsules 3, 4), preferably has a relatively symmetrical shape, such as a rectangular or elliptical / oval shape. A longitudinal direction X is defined, which corresponds to the direction in which the receiving device is inserted into the receiving housing 32. Therefore, when the receiving device 5 is inserted into the mixer 6, the longitudinal direction X coincides with the insertion direction.

[0070] Advantageously, the mixer 6 is configured to mix the first and second agents inside the receiving device 5 , preferably inside the first capsule 3 and the second capsule 4 , without any of the agents coming into contact with the manufacturing device 2 .

[0071] As mentioned above, some of the embodiments described here can be applied to a production device 2 without a receiving device 5, ie the first and second capsules 3, 4 can be positioned directly in the mixer.

[0072] Advantageously, the first formulation is the first phase of the cosmetic product to be manufactured, for example the oil phase of the cosmetic product, and the second formulation is the second phase of the cosmetic product, for example the aqueous phase of the cosmetic product. For example, the oil phase may constitute the basis of the cosmetic product to be manufactured, and the aqueous phase may contain active ingredients and thus constitute a complex of active ingredients of the cosmetic product to be manufactured.

[0073] Cyst

[0074] The two capsules that can be used in the manufacturing device 2 shown are described in detail in document FR 1 755 744, and its description of the capsules is fully incorporated herein.

[0075] Such capsules are not the object of the present invention. The following points will be retained for the rest of the specification.

[0076] More specifically, if Figure 2A , 2B As shown in Figures 3A, 3B, 4A, and 4B, the first and second capsules 3 and 4 are different from each other and are configured to be fluidically coupled to each other. In addition, each of the first and second capsules 3 and 4 is advantageously for single use.

[0077] The first capsule 3 comprises a first deformable compartment 3.1 having a convex shape for accommodating a first agent, a first connection portion 3.2 and a first connection channel 3.3 configured to fluidically connect the first deformable compartment 3.1 and the first connection portion 3.2. Advantageously, the first connection channel 3.3 is formed by a first connection groove. Advantageously, the first connection portion 3.2 comprises a female connection end piece 3.4, for example cylindrical, which is fluidically connected to the first connection channel 3.3. The first capsule 3 comprises a plane 3.7 through which the connection portion 3.2 passes.

[0078] The first capsule 3 further comprises an outlet channel 3.5, for example an outlet slot, which is fluidically coupled to the first coupling channel 3.3 and is provided with an outlet orifice 3.6. Advantageously, the outlet channel 3.5 extends in the extension of the first coupling channel 3.3 and substantially parallel to the first coupling channel 3.3. In the present case, the outlet channel 3.5 can equally be mounted on the first capsule 3 or on the second capsule 4. In practice, the outlet channel 3.5 is only operatively loaded after the manufacturing device 2 has been used.

[0079] The second capsule 4 comprises a second deformable compartment 4.1 having a convex shape for accommodating a second agent, a second connection portion 4.2 configured to be connected to the first connection portion 3.2, and a second connection channel 4.3 configured to fluidically connect the second deformable compartment 4.1 and the second connection portion 4.2. Advantageously, the second connection channel 4.3 is formed by a second connection groove, and the second connection portion 4.2 extends substantially perpendicular to the second connection channel 4.3. More specifically, the second connection portion 4.2 comprises a male connection end piece 4.4, for example cylindrical, which is fluidically connected to the second connection channel 4.3 and is configured to receive the female connection end piece 3.4 in a sealed manner. The second capsule 4 comprises a plane 4.7 through which the second connection portion 4.2 passes.

[0080] The first and second capsules 3, 4, more specifically the first and second deformable compartments 3.1, 4.1, are each closed by a connecting weld ensuring the sealing of the first and second capsules 3, 4, these connecting welds being breakable when threshold pressures are reached. These threshold pressures can be reached in the mixer 6. Again, these connecting welds are described in detail in the description of document FR 1755744.

[0081] Each of the first and second capsules 3, 4 is configured to contain all or substantially all of a mixture formed by a predetermined amount of a first agent and a predetermined amount of a second agent. In this regard, the deformable compartment is flexible or provides a cushioning area. Again, the description of the document filed with application number FR 1755744 specifically describes this.

[0082] Receiving device

[0083] like Figure 2A , 2B , 3A, 3B, 4A, 4B and 5 more specifically show that the receiving device 5 can adopt 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, and in the closed position, the receiving device 5 can hold the first and second capsules 3, 4 in place.

[0084] The receiving device 5 is more specifically in the form of a receiving box 7 ( Figure 2A , 2B), the receiving box is configured to at least partially receive and accommodate the first and second capsules 3, 4. The receiving device 5 specifically comprises a first protective shell 8 and a second protective shell 9, which are arranged around a hinge axis 10 (or hinge) in a first position (see Figure 2A , 2B , 5) and the second position (see Figure 4A , 4B ) are hingedly mounted relative to each other, the first position corresponding to the open position of the receiving device 5, and the second position corresponding to the closed position of the receiving device 5. The receiving device 5 also includes a first support portion 11 and a second support portion 12, both of which are arranged in the receiving box body 7. The first and second support portions 11, 12 respectively include a first receiving position 13 configured to receive the first capsule 3 and a second receiving position 14 configured to receive the second capsule 4. The first and second protective shells 8, 9 each include a hole 8.2, 9.2 to allow access to the first or second receiving position 13, 14. These holes 8.2, 9.2 define an insertion surface of the receiving device 5. The receiving device 5 includes a removal surface opposite to the insertion surface.

[0085] Advantageously, the first support portion 11 comprises a receiving wedge 15 configured to receive a peripheral portion of the first capsule 3, and the second support portion 12 comprises a receiving wedge 15 configured to receive a peripheral portion of the second capsule 4. These receiving wedges 15 partially define the first and second receiving locations 13,14.

[0086] The first supporting portion 11 comprises a first resting surface 11.1 which is configured to guide (have contact with) and receive the flat face 3.7 of the first capsule 3. The first resting surface 11.1 thus partially defines the first receiving location 13.

[0087] Likewise, the second support portion 12 comprises a second resting surface 12.1 configured to guide (have contact with) and receive the flat face 4.7 of the second capsule. Thus, the second resting surface 12.1 partially defines the second receiving location 14.

[0088] When the first and second capsules 3, 4 are inserted, their respective planes 3.7, 4.7 face each other, with the two resting surfaces 11.1, 12.1 being located between the planes.

[0089] In order to allow the first and second connection portions 3.2, 4.2 of the first and second capsules 3, 4 to pass through, the first and second placement surfaces 11.1, 12.1 each include a portion along the insertion axis X( Figure 1A ) channel holes 11.2, 12.2 in the form of narrow slots open to the outside.

[0090] The receiving device 5 further comprises a partition wall 22 ( Figure 3A , 3B). The partition wall 22 is located between the first and second receiving positions 13, 14. Moreover, the partition wall is fixed to the first support portion 11. The partition wall 22 includes a passage hole 22.2 to allow the first and second connecting parts 3.2, 4.2 to be positioned in the receiving device. The passage hole 22.2 is in the form of a through groove in thickness and open to the outside.

[0091] Thus, the holes 11.2, 22.2, 12.2 form a space for accommodating the connecting end pieces 3.4, 4.4 of the first and second capsules 3,4.

[0092] A first actuation surface 8 . 1 comprising the first shell 8 and the first support portion 11 and a second actuation surface 9 . 1 comprising the second shell 9 and the second support portion 12 are also defined.

[0093] Each actuation surface 8.1, 9.1 participates in transmitting the force received by the receiving device 5 towards the first and second capsule 3, 4. This will be explained in detail below.

[0094] Articulation

[0095] according to Figure 2A , 2B , 3A, 3B, 5, the first shell 8 and the second shell 9 are in a receiving position relative to each other around the hinge axis 10 (see Figure 2A , 2B , 3A, 3B) and connection position (see Figure 4A , 4B ), in the receiving position, the first shell 8 and the second shell 9 are away from each other, and the first capsule 3 and the second capsule 4 can be received in the first receiving position 13 and the second receiving position 14 respectively, and in the connecting position, the first shell 8 and the second shell 9 are close to each other, and the first capsule 3 and the second capsule 4 are pre-connected with each other. Pre-connecting with each other means that the male connecting end piece 4.4 of the second capsule 4 is partially introduced into the female connecting end piece 3.4 of the first capsule 3, however, no sealing connection is established between these first capsule 3 and the second capsule 4.

[0096] The first and second shells 8, 9 may, for example, have an inclination angle greater than or equal to 7° and, for example, about 7° when they are in the receiving position, and may be substantially parallel relative to each other when they are in the connected position. More specifically, there are two main components 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.

[0097] Advantageously, the first and second shells 8,9 (or actuation surfaces 8.1,9.1) are configured to engage the first connection part 3.2 in the second connection part 4.2 when the receiving device 5 is moved to the closed position. In fact, when the first and second shells 8,9 are in the closed position, the connections 3.2,4.2 partially nest in each other.

[0098] More specifically, the first support portion 11 and the second support portion 12 are configured such that when the first shell 8 and the second shell 9 are in the connected position, the first capsule 3 and the second capsule 4 extend substantially parallel to each other. Figure 4A , 4B As shown, when the first capsule 3 is received in the receiving device 5 and when the receiving device is in the closed position, the first capsule 3 is configured to partially extend to the outside of the receiving device 5. Advantageously, when the first capsule 3 is received in the receiving device 5 and when the receiving device 5 is in the closed position, the outlet hole 3.6 is configured to extend to the outside of the receiving device 5.

[0099] Heating elements

[0100] Manufacturing equipment 2 includes Figure 3A , 3B A heating element 46 (also referred to as a "heater element") is visible in the drawing. In the embodiment shown in the figures, the heating element 46 is part of the receiving device 5. However, in the absence of a receiving device 5, the heating element can be integrated into the mixer.

[0101] The heating element 46 is connected to the partition wall 22. When designing, the heating element 46 is selected on one side of the first support portion 11, which means that the heating element 46 is installed on one side of the partition wall 22 on the first support portion 11.

[0102] The heating element 46 preferably comprises one or more electrical heating resistors 46.1 and a diffusion plate 46.2. The heating element 46 thus has a planar shape to better diffuse the heat, if possible with a minimum of 500 mm 2 , and preferably about 800mm 2 surface area.

[0103] However, since the first support portion 11 is located between the first bladder 3 and the heater element 46, a communication hole 46.3 is provided in the first support portion 11 so that the plane 3.7 of the first bladder 3 is directly connected to the heater element 46 (ie, separated only by air).

[0104] Electrical contact rails for heating elements

[0105] The heating element 46 needs to be powered. Preferably, the receiving device 5 does not comprise its own battery and must be powered when it is inserted into the receiving housing 32.

[0106] Thus, an electrical connection is provided between the receiving device 5 and the mixer 6 .

[0107] The receiving device 5 comprises an insertion face, where the holes 8.2, 9.2 are located, which is the face that first enters the receiving housing 32, and an opposite withdrawal face, which is the visible face when the receiving device 5 is inserted into the receiving housing 32. The receiving device 5 also comprises a first actuation face 8.1 and an opposite second actuation face 9.1.

[0108] Finally, the receiving device 5 comprises a first connection face 23 and a second connection face 24, preferably opposite each other. Figure 2A , 2B In the embodiments shown in FIGS. 3A, 3B, 4A, 4B, the connection surfaces 23 and 24 correspond to the side surfaces of the heating element 46 and are therefore different from the first and second actuation surfaces 8.1, 9.1 and the insertion / removal surface.

[0109] The connecting surfaces 23, 24 extend between the actuating surfaces 8.1, 9.1 of the receiving device 5. Preferably, the connecting surfaces 23, 24 couple the actuating surfaces 8.1, 9.1 of the receiving device 5 together, ie they are abutting.

[0110] The overall shape of the receiving device 5 is selected so that the connection surfaces 23, 24 are spaced further apart from each other than the actuation surfaces 8.1, 9.1 (and than the insertion / removal surface). In other words, if one considers the smallest parallelepiped into which the receiving device 5 is inserted, the surface that contacts the connection surfaces 23, 24 is further away than the surface that contacts the actuation surfaces 8.1, 9.1 and closer than the surface that contacts the insertion / removal surface. This results in the receiving device 5 being wider than it is thick (and, moreover, taller than it is wide).

[0111] The first connection face 23 comprises a first electrical contact track 23.1 for supplying power to the heater element 46, and the second connection face 24 comprises a second electrical contact track 24.1 (Figs. 2A, 3A, 3B, 4A, 4B) also for supplying power to the heater element 46. Thus, the electrical contact tracks 23.1, 24.1 are outside the receiving device 5 in order to make contact with the complementary tracks ( Figure 2A , 4A , 4B).

[0112] This configuration has several advantages: firstly, it ensures a simple and effective electrical connection. It also avoids the risk of short circuits. In fact, in the event of a liquid flowing in the receiving housing 32 (e.g. shower or sink water or just a burst capsule), it is unlikely that the two electrical contact rails 23.1, 24.1 will be affected by the same liquid at the same time.

[0113] The first connection surface 23 includes the first shell 8 and the second shell 9 , the first support portion 11 , and a portion of the partition wall 22 .

[0114] In particular, the first connection surface 23 comprises a longitudinal groove 23.2 having a bottom 23.21 and two side walls 23.22, 23.23. The first electrical contact rail 23.1 is preferably positioned on the side walls 23.22 of the longitudinal groove 23.2. Figure 3A , 3B In the embodiment shown, the bottom 23.21 and the side wall 23.23 are made from a portion of the first support portion 11. Appropriate cutouts 8.5 are then provided in the first shell 8 to leave room for the longitudinal groove 23.2. The opposite side wall 23.22 is made from a portion of the partition wall 22. The first electrical contact rail 23.1 is then positioned on this side wall 23.22 (because the heater element 46 is mounted on the partition wall).

[0115] Likewise, a similar longitudinal groove 24.2 is provided on the second connection face 24, with the cutout 9.5 in the second shell 9, as well as a bottom 24.21 and two opposite side walls 24.22, 24.23. Due to the non-centering of the groove, the cutout 9.5 in the second shell 9 is significantly less noticeable than the cutout 8.5 in the first shell 8.

[0116] The grooves 23.2, 24.2 are configured to engage corresponding complementary guide rails 31.1, 31.2 (sliding links) provided on the (preferably opposite) connection sides in the receiving housing 32 ( Figure 1A , 7A ). Thus, the grooves 23.2, 24.2 form a relief extending over the entire height of the portion where the receiving device 5 is located, at least up to the insertion height. The complementary guides 31.1, 31.2 contribute to defining the receiving housing 32 and are located on opposite edges.

[0117] exist Figure 4A , 4B In one embodiment, which can be seen particularly in FIG. , the electrical contact rails 23 . 1 , 24 . 1 are not located at the same level, but are offset.

[0118] The electrical contact rails 23 . 1 , 24 . 1 may take several forms: electrical pins, metal sheets (as shown), etc. The electrical contact rails 23 . 1 , 24 . 1 are preferably slightly deformable to ensure permanent contact when the receiving device 5 is placed in the receiving housing 32 .

[0119] Therefore, it is noted that the longitudinal grooves 23.2, 24.2 are not centered relative to the first and second actuation surfaces 8.1, 9.1 (see in particular Figure 2A , 4A , 4B). In terms of design, this is represented by a groove formed essentially in the first support portion 11 and the first protective shell 8.

[0120] The benefit of this asymmetry is the error-proofing function. In fact, it is impossible to place the receiving device 5 in the wrong orientation (according to a 180° rotation about the longitudinal axis X) because the grooves 23.2, 24.2 will not be inserted into the guides 31.1, 31.2 and the second shell 9 will abut against the guides.

[0121] In order to have a foolproofing effect for vertical rotation (i.e. by first trying to place the removal face instead of the insertion face), the longitudinal grooves 23.2, 24.2 do not extend over the entire height of the portion of the first shell 8 or the second shell 9 in which they are located. Thus, without having to provide specific components, the stop effect is simply obtained by the undulation effect through the non-through portion of the first shell 8 or the second shell 9. In other words, when the receiving device 5 is in the wrong orientation, the first shell 8 or the second shell 9 prevents the grooves 23.2, 24.2 from being inserted onto the guide rails 31.1, 31.2.

[0122] In addition, the longitudinal grooves 23.2, 24.2 each include an end stop 23.3, 24.4 located on the side of the removal face. These end stops 23.3, 24.4 serve as insertion stops to define a maximum insertion position in the receiving housing 32.

[0123] In fact, it has two different types of stops, but they are located substantially in the same position: at the ends of the longitudinal grooves 23.2, 24.2.

[0124] Electrical contact rails for temperature sensors

[0125] Since the heater element 46 is mainly used to heat the first capsule 3, the first support portion 11 is more conducive to supporting the walls 23.23, 24.23 of the grooves 23.2, 24.2 than the second support portion 12.

[0126] In practice, a temperature sensor (not visible in the figure) adjoins the back side of the diffuser plate 46.2 to measure the temperature in the vicinity of the first receiving location 13 and therefore the temperature of the first capsule 3. The temperature sensor is therefore preferably arranged in the receiving device 5, but it can also be integrated directly into the mixer 6, in particular when no receiving device 5 is provided.

[0127] The temperature sensor is usually an NTC (negative temperature coefficient) thermistor, but can also be an infrared temperature sensor or a thermocouple.

[0128] The temperature sensor must also be electrically connected to the mixer 6 (in particular, ultimately to a processor, in order to collect data) and to a battery 44 with which the mixer 6 is equipped, in order to power the temperature sensor. For this purpose, a first additional electrical contact track 46.51 is provided at the level of the first contact surface 23. This first additional electrical contact track 46.51 is different from the first electrical contact track 23.1. More specifically, the first additional electrical contact track 46.51 is provided in the first recess 23.2, on the side wall 23.23, i.e. on the side wall formed by the first support portion 11.

[0129] Similarly, a second additional electrical contact track 46 . 52 is arranged in the second recess 24 . 2 .

[0130] The two additional electrical contact rails 46.51, 46.52 are also advantageously offset. In the specific example, the additional electrical contact rail 46.51 and the electrical contact rail 24.1 are at the same level, and the additional electrical contact rail 46.52 and the electrical contact rail 23.1 are at the same level.

[0131] Figure 2A , 3A , 3B, 4A, 4B, 5 show these tracks.

[0132] An additional temperature sensor (not shown) may be provided in the receiving device 5, or directly in the mixer 2, to measure, preferably continuously, the room temperature. This additional temperature sensor may thus allow adjusting the measurement threshold of the above-mentioned temperature sensor, in particular in order to have a more reliable measurement of the temperature of the contents of the capsule.

[0133] Error proofing structure

[0134] The receiving device 5 includes an error-proofing structure 17 to ensure that the first and second capsules 3, 4 are correctly positioned, that is, the "correct" capsule 3, 4 is placed in the "correct" receiving position 13, 14 (in Figure 2A , 5 The error-proofing structure 17 is preferably located at the ends of the passage holes 11.2, 12.2 to block the unwanted passage of the connection end pieces 3.2, 4.2.

[0135] The error-proofing structure 17 comprises at least one flap 17 . 1 opening outwardly from the receiving device 5 (preferably, as shown, there are two flaps on each side; preferably, the two flaps 17 . 1 have a barroom configuration, ie, are hinged outwardly from the receiving device 5 by hinges).

[0136] In particular, the error-proofing structure 17 achieves two different functions.

[0137] The flap 17.1 comprises a hole 17.2 of a shape complementary to the female connection end piece 3.4 of the first capsule 3, to allow its insertion into the hole 8.2. Furthermore, the flap 17.1 comprises a stopper 17.3 which helps to define the hole 17.2, to prevent the second connection part 4.2, which is transversely longer than the first connection part 3.2, from being inserted into the hole 8.2. In fact, attempting to insert the second capsule 4 into the first receiving position 13, the end of the second connection part 4.2, i.e. a part of the male connection end piece 4.4, comes into contact with the stopper 17.3.

[0138] In order to access the second receiving position 14, when the receiving device 5 is in the closed position, the error-proofing structure 17 blocks it: the passage hole 12.2 is preferably also blocked by the stopper 17.3. On the other hand, when the receiving device 5 is in the open position, that is, when the second shell 9 has been rotated about its hinge, the passage hole 12.2 is released.

[0139] Finally, since the flap 17 . 1 opens outwards, it does not functionally block during the extraction of the first and second capsules 3 , 4 (and both simultaneously when they are attached) from the receiving device 5 .

[0140] Depending on the design of the relative movement of the components, the error-proofing structure 17 can be attached to the first support part 11 or to the second support part 12 (as shown in the figure): if the second support part 12 is attached to the second housing 9 (and is therefore rotationally movable relative to the first support part 11), it is preferred to attach the error-proofing structure to the first support part 11. In other words, it does not matter.

[0141] The return spring 17.4 keeps the error-proofing structure 17 in the default position, ie the closed position.

[0142] Pressing element - blade

[0143] like Figure 2B , 3A 3B, the receiving device 5 also includes a first pressing element 19 and a second pressing element 21, the first pressing element being configured to penetrate into the interior of the second receiving position 14, that is, to apply pressure to the first capsule 3, more specifically, to apply pressure to the first deformable compartment 3.1, and the second pressing element being configured to penetrate into the interior of the first receiving position 13, that is, to apply pressure to the second capsule 4, more specifically, to apply pressure to the second deformable compartment 4.1.

[0144] The first pressing element 19 (or the second pressing element 21) is preferably mounted on the first supporting portion 11 (or the second supporting portion 12) and is movable between an inactive position (or an unfolded position) and an active position (or a folded position), in which the first or second receiving position 13, 14 can be approached by the first or second capsule 3, 4 (see Figure 2B , 3A, 3B), in the active position or the folded position, the first pressing element 19 (or the second pressing element 21) penetrates into the interior of the first receiving position 13 (or the second receiving position 14), that is, it is able to exert pressure on the first deformable compartment 3.1 of the first capsule 3 (or the second deformable compartment 4.1 of the second capsule 4).

[0145] The first pressing element 19 (or the second pressing element 21) is advantageously mounted movably to rotate about a hinge 19.1 (or hinge 21.1). The hinge 19.1 (or hinge 21.1) is positioned opposite the hole 8.2 (or hinge) of the first shell 8 (or second shell 9). Therefore, both hinges 19.1, 21.1 are located near the removal surface of the receiving device 5.

[0146] The pressing elements 19, 21 have flat inner surfaces 19.2, 21.2, respectively, to form blades capable of rotational movement. Each flat inner surface 19.2, 21.2 cooperates with its corresponding first or second capsule 3, 4. When the pressing element is pressed, the space between the blade and the placement surface 11.1, 12.1 is gradually and continuously reduced. When the first capsule 3 or the second capsule 4 is installed, the outlet hole 3.6 and the connection part 3.2, 4.2 are located on the side opposite to the hinge 10: this allows the cream to be effectively discharged from the first capsule 3 or the second capsule 4, while avoiding any unwanted stagnation area inside it.

[0147] In order to keep the pressing elements 19, 21 in the open position by default (ie when the receiving device 5 is not actuated or when the second shell 9 is in the pivoted position), a reset device 21.3 (such as a spring) is arranged to abut against the first shell 8 or the second shell 9 ( Figure 5 ). The resetting means 21.3 may tend to push the leaf which extends slightly on the other side of the hinge 21.1.

[0148] In use, as will be described below, the two pressing elements 19, 21 are actuated successively to allow the cream to be stirred.The cream then flows from the first or second capsule 3, 4 to the other second or first capsule 4, 3.

[0149] Preferably, to optimize the operation of the blade, the hinge 19.1 (or hinge 21.1) defines an axis of rotation included in the plane of the placement surface 11.1 (or placement surface 12.1) and orthogonal to the longitudinal axis of the receiving device 5. Without a capsule, the inner surface 19.2, 21.2 can be pressed against the placement surface 11.1, 12.1.

[0150] Likewise, the hinge 19 . 1 , 21 . 1 is preferably located exactly at the end of the first or second receiving location 13 , 14 .

[0151] In order to move the pressing elements 19, 21, the first and second shells 8, 9 each preferably include a pressing point 8.3, 9.3 facing the tip portion of the blade (to take advantage of the leverage and minimize the applied force), which is configured to receive an external force, which will be described in more detail later. The pressing point 8.3, 9.3 is attached to a deformable flexible area 8.4, 9.4 (made of an elastomer or the like). The flexible area 8.4, 9.4 itself is attached to the rest of the first shell 8 or the second shell 9 made of a more rigid plastic.

[0152] The pressure points 8.3, 9.3 are made of a rigid material, usually plastic.

[0153] Alternatively (not shown), the first and second shells 8 , 9 have two holes, preferably facing the end portion of the blade, to allow free access to the pressing elements 19 , 21 .

[0154] The user can grasp the receiving device 5 with one hand and simultaneously press the pressure points 8.4, 9.4, for example with the thumb and index / middle finger. The simultaneous pressure allows the cream to be directed from the first and second capsules 3, 4 to the outlet opening 3.6.

[0155] In another embodiment not shown, the receiving device 5 is integrated into the mixer 6 and the blades can be directly integrated into the mixer 6 .

[0156] Keep the stopper

[0157] In order to prevent the receiving device 5 from being removed from the receiving housing 32 during the mixing process, a holding mechanism 50, which will be described in detail later, is provided in the manufacturing device 2. In order to enable the holding mechanism 50 to have a clamping force on the receiving device 5, a holding stopper 9.6 is provided in one of the first or second housings 8, 9 (in Figure 2A , 2B , 3A, 3B, 4B, 5 on the second housing 9). This retaining stop 9.6 corresponds essentially to a radially extending protrusion, i.e. in a plane orthogonal to the longitudinal direction X. It may be present at any position along the height of the receiving device 5. In the exemplary embodiment shown, the retaining stop 9.6 is arranged near the insertion face.

[0158] A further stop may be provided on the further shell, for example for ergonomic reasons.

[0159] Grab handle

[0160] In order to allow the user to grasp the receiving device 5 when it is inserted into the receiving housing 32, gripping handles 8.7, 9.7 are provided on each of the first and second protective shells 8, 9 (particularly visible in Figures 1, 2B, 4A, 4B). These gripping handles 8.7, 9.7 are located at the level of the extraction surface, which is accessible when the receiving device 5 is in place.

[0161] The gripping handle 8.7, 9.7 may simply consist of a radially extending protrusion, ie extending in a plane orthogonal to the longitudinal direction X long enough that a part of a user's knuckle can pull it.

[0162] Connect Button

[0163] As mentioned above, the actuation surfaces 8.1, 9.1, more specifically the first and second protective shells 8, 9 each comprise a pressure point 8.3, 9.4 to transmit the force towards the inner pressure element 19, 21. These pressure points 8.3, 9.4 are formed in the flexible areas 8.4, 9.4.

[0164] When the receiving device 5 is switched to the closed position, the connecting end pieces 3.4, 4.4 face each other and are partially nested. In order to form a sealed and reliable fluid connection between the first and second capsules 3, 4, a coupling mechanism 52 is provided in the manufacturing device 2. The coupling mechanism 52 applies a force to the receiving device 5. The coupling mechanism 52 allows both the establishment of a fluid connection between the first and second capsules 3, 4 under the effect of the force applied by the coupling mechanism 52 and the avoidance of any undesired disconnection of the first and second capsules 3, 4 under the effect of the pressure generated by the agitation of the first and second capsules 3, 4. This will be described below.

[0165] One of the first or second protective shells 8, 9 (or even both) comprises a coupling button 9.8 (movable in the direction of the second receiving position 14) Figure 2A , 2B , 3A, 3B, 4A, 4B, 5). More specifically, since the coupling button 9.8 is used to press the second capsule 4 near the connecting portion 4.2, it can be moved in the direction of the area close to the orifice 9.2. Here, the coupling button 9.8 is attached to a flexible area, which can be the flexible area 9.4 of the pressing point 9.3. It is noted here that the coupling button 9.8 is different from the pressing point 9.3.

[0166] The coupling button 9.8 is preferably rigid to better transmit the force of the coupling mechanism 52 to the first capsule 3 and the second capsule 4, thus maintaining the coupling.

[0167] Mixer

[0168] like Figure 6 , 7A , 7B, 8A, 8B, 8C, 9, 10A, 11A, 11B, 11C, the mixer 6 comprises a support 31 and a receiving housing 32, which is at least partially defined by the support 31 and is configured to receive at least a portion of the receiving device 5. Figure 1A 1B, the mixer 6 and the receiving device 5 are configured such that when the receiving device 5 is received in the receiving housing 32, the receiving device 5 at least partially extends out of the mixer 6.

[0169] The support 31 is similar to a base, ie it defines the entirety of the fixing element when the mixer 6 is placed on a support (table, worktop, etc.), whether the mixer is in use or not.

[0170] The support 31 of the mixer 6 further comprises a housing 33 and an insertion hole 34 opening outwardly into the receiving housing 32, and the receiving device 5 is configured to be inserted into the receiving housing 32 through the insertion hole 34. Advantageously, the insertion hole 34 is arranged in a central part of the upper surface of the base 33 and is configured to be oriented upward when the mixer 6 is arranged on a horizontal support surface (table, work surface, etc.).

[0171] The base 33 also serves as an outer housing having a desired design for the mixer. The base 33 may include a lower base and an upper base.

[0172] Actuation system

[0173] The mixer 6 further comprises an actuation system 35 which is pivotally mounted on the support 31 about a substantially vertical pivot axis 36 when the mixer 6 is arranged on a horizontal support surface (table, worktop, etc.). Figure 6 , 8A , 8B, 8C, 9, 10A).

[0174] Preferably, the actuation system 35 performs a reciprocating movement about the pivot axis 36 along a maximum angular displacement of 45°. The movement thus consists of a rotation of a maximum of +45° then -45°, etc. The movement is performed along a nominal stroke C35 (not shown in the figures) which is associated with the maximum angular displacement in the case of a rotation about the pivot axis 36. The nominal stroke C35 of the actuation system 35 is defined as the stroke between the two extreme positions of said actuation system 35. The neutral position of the actuation system 35 is defined between these two extreme positions, the neutral position of the actuation system 35 corresponding to the insertion position in which the receiving device 5 can be positioned in the receiving housing 32 of the mixer 6 without being disturbed by the actuation system 35.

[0175] The mixer 6 further comprises a drive motor 39 mounted on the support 31. The drive motor 39 is configured to pivot the actuation system 35 about the pivot axis 36 within a predetermined angular range. Preferably, the drive motor 39 rotates in a single direction only.

[0176] 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, and the second actuation member may include a second actuation finger 38.1 opposite to the first actuation member 37 and configured to transmit pressure to the second capsule 4.

[0177] The first and second actuating members 37 , 38 are configured to be arranged on either side of the receiving housing 32 and thus on either side of the receiving device 5 when the receiving device is received in the mixer 6 , and more specifically in the receiving housing 32 .

[0178] The actuating members 37, 38 have at least one position in which they are at least partially located inside the receiving housing 32. In the neutral position of the actuating system 35, the actuating members 37, 38 are arranged relative to the receiving housing 32 to allow the receiving device 5 to be positioned inside the receiving housing 32 of the mixer 6; it is the insertion position.

[0179] The first actuating member 37 and the second actuating member 38 are more specifically configured to apply pressure on the first pressing element 19 and the second pressing element 21 respectively and alternately to transfer the pressure to the first compartment 3.1 and the second compartment 4.1 respectively and alternately. In particular, the first actuating member 37 and the second actuating member 38 are configured to cooperate with the first pressing point 8.3 and the second pressing point 9.3 of the first protective shell 8 and the second protective shell 9 respectively, or directly cooperate with the pressing elements 19, 21.

[0180] An actuation stroke C37 is defined for the first actuation member 37 , and an actuation stroke C38 is defined for the second actuation member 38 .

[0181] The actuation stroke C37 is defined as the stroke of the first actuation member 37 between the neutral position of the actuation system 35 and the maximum actuation position of the first actuation member 37 , in which the first actuation member 37 is at maximum compression on the first pressing element 19 .

[0182] In contrast, the actuation travel C38 is defined as the travel of the second actuation member 38 between the neutral position of the actuation system 35 and the maximum actuation position of the second actuation member 38 , in which the second actuation member 38 is at maximum compression on the second pressing element 21 .

[0183] Preferably, the movement of the actuation system 35 can be followed using various sensors, in particular Hall effect sensors. More specifically, each of the first actuation member 37 and the second actuation member 38 can include a magnet for interacting with a fixed Hall effect sensor. Advantageously, the Hall effect sensor can be directly arranged on the monitoring unit 45, which will be described later, such as Fig.12 As shown. The monitoring unit 45 can thus follow the movement of the actuation system 35, and even the movement of each of the first actuation member 37 and the second actuation member 38. It is even conceivable that the monitoring unit 45 can accurately know the position of each of the first actuation member and the second actuation member within their respective actuation strokes C37, C38, for example by arranging a plurality of Hall effect sensors.

[0184] According to the embodiment shown in FIGS. 1 to 12 , the first actuation member 37 and the second actuation member 38 extend substantially in the same plane of extension and converge opposite the pivot axis 36 .

[0185] like Figure 6 , 8A , 8B, 8C, 9, the actuation system 35 has a substantially annular shape defining a hole around the receiving housing 32. In one embodiment, the actuation system 35 is substantially formed as a single component including a hole for receiving a shaft defining the pivot axis 36.

[0186] The first and second actuating members 37, 38 are arranged respectively on opposite sides of the actuating system 35. Thus, the actuating system 35 extends twice, two by two, on two opposite faces: the actuating members 37, 38, the hole for the pivot shaft 36 and the drive mechanism with grooves (which will be described later).

[0187] The actuating members 37, 38 may each comprise a drive support 37.3, 38.3 which meet on one side at the level of the pivot axis 36. On the other side, a connecting section 36.1 is defined which connects the two drive supports 37.3, 38.3. The connecting section 36.1 may be connected to or from the same material as the drive supports 37.3, 38.3.

[0188] Preferably, the two actuating members 37, 38 rotate about the same pivot axis 36. In this case, preferably, the two drive supports 37.3, 38.3 are rotationally fixed.

[0189] However, it is possible to provide a pivot axis for each of the actuating members 37 , 38 ; however, some simple adjustments would have to be made.

[0190] Alternatively, in an embodiment not shown, the actuating member is movable in translation.

[0191] spring

[0192] The actuation system 35 moves along a nominal travel C35 to exert a force on the receiving device 5 .

[0193] However, play in the kinematic chain related to manufacturing tolerances can disturb the transmission of force by offsetting the positioning of the actuation system 35. Thus, once at the end of the stroke, there may be a lack of a few millimeters or, conversely, an excess of a few millimeters. This can lead to insufficient compression or, conversely, damage to the manufacturing device 2.

[0194] To overcome this, the actuation system 35 may include springs 37.4, 38.4 (at Fig. 8A , 8B, 8C). In particular, the springs 37.4, 38.4 are configured to compress when the actuation system 35 reaches the vicinity of the nominal end of its stroke C35 and when the actuation fingers 37.1, 38.1 abut against the planes 3.7, 4.7 of the capsule. Thus, the springs 37.4, 38.4 generate a force tending to move the actuation members 37, 38 away from the receiving device 5.

[0195] More specifically, each actuating member 37, 38 comprises a spring 37.4, 38.4.

[0196] The springs 37.4, 38.4 may be located at different positions. In an embodiment not shown, the springs 37.4, 38.4 are located at the "free" ends of the fingers 37.1, 38.1.

[0197] In another preferred embodiment, because the spring is hidden, the spring 37.4, 38.4 is installed between the finger-shaped member 37.1, 38.1 and the drive support member 37.3, 38.3. Like this, because the spring is located behind the base, the user cannot approach it.

[0198] In order to place the spring in this position, it is convenient to provide, for each actuating member 37, 38, an arm 37.2, 38.2 movably mounted relative to the drive support 37.3, 38.3. The finger 37.1, 38.1 is then fixedly mounted to the arm 37.2, 38.2.

[0199] exist Fig. 8A , 8B In the embodiment specifically shown in FIGS. 8C and 9, the arms 37.2 and 38.2 are rotatably movable relative to the drive supports 37.3 and 38.3 via hinges 37.5 and 38.5. Springs 37.4 and 38.4 are positioned between the arms 37.2 and 38.2 and the drive supports 37.3 and 38.3.

[0200] Therefore, the spring 37.3, 38.3 works in a compressed state, in the sense that its rest position or unstressed position is not compressed. It is compressed in the translation or rotation direction of the actuating member 37, 38.

[0201] The springs 37.3, 38.3 may be of the helical type or leaf springs, or even comprise an elastic material or elastic component (elastomer, gas bubble, etc.).

[0202] Rotary drive

[0203] according to Figure 6 , 8A In the embodiments shown in FIGS. 8B, 8C and 9, the mixer 6 further comprises a cam 41 in the form of a drive wheel or arm, rotatably fixed to the output shaft 39.1 of the drive motor 39 and configured to be driven to rotate around its cam rotation axis 41.1. The cam 41 is mounted on the support 31.

[0204] In order to achieve a reciprocating motion with a large lever arm, it is preferred that the pivot shaft 36 and the cam 41 are located on both sides of the receiving housing 32 .

[0205] The cam 41 is equipped with a drive finger 42 which is eccentric with respect to the cam rotation axis 41 . 1 .

[0206] The cam 41 is usually driven by the drive motor 39 using one or more belts. In this case, starting from the drive motor 39 and the output shaft 39.1 on which the pulley is mounted, the kinematic chain is as follows: belt 39.2, pulley 39.3 coupled to pulley 39.4 by a shaft, belt 39.5, cam 41.

[0207] The drive finger 42 is received in a drive recess 43 provided on the actuation system 35. In particular, the drive recess 43 is configured in the connecting section 36.1. The drive recess 43 is elongated and extends in a direction of extension substantially parallel to the pivot axis 36. This configuration of the mixer 6 allows the reciprocating movement of the actuation system 35 to be obtained by rotating the drive motor 39 always in the same direction of rotation, thereby eliminating the need for an expensive control system with the aid of the drive motor 39.

[0208] The drive groove 43 extends along its depth in the direction of the pivot axis 36 .

[0209] The coupling between the drive groove 43 and the drive finger 42 will now be described. The alignment of the drive groove 43 and the drive finger 42 is variable due to the rotation of the actuating member 35, which means that a simple adjustment will hinder the system. Instead, the presence of a gap that causes misalignment generates noise and gives a delay time at each end of travel.

[0210] To solve this problem, a ball joint is provided between the drive finger 42 and the drive groove 43, which allows previous misalignments to be addressed.

[0211] In particular, a ball 42.1 housed in a ring 43.1 is mounted on the drive finger 42. The connection between the ball 42.1 and the ring 43.1 is a ball-and-socket joint. The ring 43.1 is partially received in the drive groove 43, in which it is movably mounted to translate in a direction parallel to the pivot axis 36 (and therefore along the length of the drive groove 43). Finally, the ball 42.1 is movably mounted to translate along the drive finger 42.

[0212] The arrangement of these various couplings may be different, in the sense that the ring may also be moved in translation along the depth of the groove and the ball may then be fixed on the drive finger.

[0213] The complete connection between the drive finger 42 and the actuation system 35 thus comprises, in sequence, a slide, a ball joint, a slide perpendicular to the other slide. Thus, in a kinematic torsor, it is noted that the force is transmittable only in one of the six components of the torsor, namely the component of the translation tangential to the rotational movement of the actuation system 35, i.e. the component that allows the rotation of the actuation system 35. The kinematic equivalent is a ball-plane connection (also called a point connection).

[0214] In order to make the above-mentioned coupling unnecessary more complicated, the cam rotation axis 41.1 and the pivot axis 36 are preferably orthogonal. This allows to have a drive finger 42 that moves in a circular motion in a plane parallel to the pivot axis 36.

[0215] The movement of some arrangements of the coupling may be accomplished simply by means of plastic / plastic slides, which wear slowly enough to ensure a satisfactory service life.

[0216] According to one variation of the invention, the mixer 6 may be configured such that rotation of the drive motor 39 in a first rotational direction causes the actuating portion 35 to pivot in a first pivot direction, and such that rotation of the drive motor 39 in a second rotational direction opposite to the first rotational direction causes the actuating portion 35 to pivot in a second pivot direction opposite to the first pivot direction.

[0217] Eccentricity of the pivot axis

[0218] The actuation members 37 , 38 move along an actuation stroke C37 , C38 , respectively.

[0219] However, in the embodiment shown in the figures, one of the two actuating members 37 , 38 has an actuating stroke C37 , C38 of a strictly greater length than the other actuating member.

[0220] This difference in the actuation strokes C37, C38 allows better mechanical and electrical management of the forces to be provided in order to deform the first capsule 3 relative to the second capsule 4. Figure 2B As shown, the first capsule 3 has a greater thickness than the second capsule 4 , which means that more space is needed on the side of the thickest capsule and the pressing element 19 will come into contact sooner and will start working sooner than the pressing element 21 .

[0221] In order to achieve this travel difference, several solutions can be envisaged. One solution consists in having a non-central drive groove 43 in the connecting part 36.1.

[0222] In particular Fig. 8A , 8B Another solution shown in , 8C, 9 consists in making the pivot axis 36 eccentric. In other words, the cam rotation axis 41.1 does not intersect the pivot axis 36. This results in a difference in travel between the two actuating members 37, 38 when the cam 41 rotates a full circle. A distance between the cam rotation axis 41.1 and the pivot axis 36 (orthogonal, i.e. by orthogonal projection) of 1% to 5% of the distance between the drive groove 43 and the pivot axis 36 is sufficient and does not interfere too much with the symmetrical appearance of the assembly. In absolute terms, a distance comprised between 1 and 2 mm is suitable.

[0223] The eccentricity may also be defined using the axis of rotation of the receiving housing 32 relative to the cam 41 : the extreme positions of the actuation system 35 are therefore not centered on the receiving housing 32 .

[0224] The eccentricity can also be defined relative to the first and second resting surfaces 11.1, 12.1 or relative to the position of the first and second capsules 3, 4 in the receiving housing 32: using planes 3.7, 4.7, an artificial plane is thus defined in the receiving housing 32. The maximum distance from the first actuation member 37 to said plane 3.7 is greater than the maximum distance from the second actuation member 38 to the plane 4.7.

[0225] In this respect, in a variant, the pivot axis 36 is comprised in a plane situated equidistant from the two resting surfaces 11 . 1 , 12 . 1 .

[0226] Under the effect of the eccentricity, the first actuating finger 37.1 is advantageously longer than the second actuating finger 38.1. This is due in particular to the fact that the extreme positions of the actuating fingers 37.1, 38.1 due to the eccentricity must be compensated. More precisely, the actuating finger 37.1, 38.1 acting on the thickest first capsule 3 or second capsule 4 has a greater length than the other actuating finger 38.1, 37.1.

[0227] Fig. 8A Another solution shown consists in not defining a neutral position of the actuation system 35 during top or bottom dead center of the cam 41. In fact, by choosing a neutral position of the actuation system 35 at a non-zero angle Ag (typically Ag comprised between 5° and 30°) relative to the 12 o'clock direction (when the mixer 6 is placed on a horizontal support), the distribution of the actuation strokes C37, C38 is offset. It should also be noted that another neutral position corresponding to an angle Ag'=180°-Ag is in fact obtained.

[0228] In practice, the actuation strokes C37 , C38 correspond, at the level of the cam 41 , to a rotation from said angle Ag up to the nearest 90° rotation (ie 3 o'clock or 9 o'clock when the mixer 6 is placed on a horizontal support) and then to a rotation from said angle Ag′ up to 270° rotation.

[0229] Since Ag and Ag' are not at 0 and 180° (12 o'clock and 6 o'clock), it is immediately noted that the strokes C37 and C38 are not equal. Therefore, when the cam 41 rotates one full circle, the first actuation stroke C37 is passed in the first direction, then the first actuation stroke C37 is passed in the second direction, then the second actuation stroke C38 is passed in the first direction, and then the first actuation stroke C38 is passed in the second direction, that is, twice the rated stroke C35.

[0230] Contact rail for mixer

[0231] As previously mentioned, the mixer 6 itself also includes electrical contact rails 31.11, 31.12 configured to engage with the electrical contact rails 23.1, 24.1 of the longitudinal grooves 23.2, 24.2 of the receiving device 5, and electrical contact rails 31.51, 31.52 configured to engage with the additional electrical contact rails 46.51, 46.52 of the longitudinal grooves 23.2, 24.2.

[0232] These electrical contact rails are mounted on the guide rails 31.1, 31.2 ( Figure 1A , 7A), which are fixed to the support 31 and mounted on the two connection sides of the receiving housing 32. The position of the electrical contact rails 31.11, 31.12 (and 31.51, 31.52) on the guide rails 31.1, 31.2 is complementary to the position of the electrical contact rails 23.1, 24.1 (and 46.51, 46.52) of the connection faces 23, 24 of the receiving device 5. The guide rails 31.1, 31.2 contribute to defining the receiving housing 32. They are, for example, located on the edge and preferably fixed to the support 31 over their entire length.

[0233] The location of the electrical contact rails 31.51, 46.51 and 31.52, 46.52 on two opposing rails 31.1, 31.2 at a distance from one another has the advantage of limiting the risk of short circuits in the event of a liquid flowing on one of the rails 31.1, 31.2 due to gravity.

[0234] Opener, connector, take-out mechanism

[0235] The mixer 6 further includes a holding mechanism 50, a coupling mechanism 52 and a clamping mechanism 54 ( Fig. 10A , 10B, 10C, 10D, 10E, 10F, 11A, 11B, 11C).

[0236] Each of these mechanisms has its own independent function. However, they can advantageously be driven simultaneously by the same auxiliary motor 40.

[0237] The holding mechanism 50 has a function of preventing the receiving device 5 from being removed while mixing is in progress.

[0238] The retaining mechanism 50 is movably mounted between an insertion position and a retaining position relative to the support 31. In the insertion position, the retaining mechanism 50 allows the insertion and removal of the receiving device 5 relative to the mixer 6. In the retaining position, the retaining mechanism 50 prevents the removal of the receiving device 5 (and thus its insertion).

[0239] The holding mechanism 50 comprises a movable element 50.1 between the two aforementioned positions, which in the holding position extends into the receiving housing 32. In particular, in the holding position, the movable element 50.1 cooperates with the holding stop 9.6 to prevent a translational movement of the receiving device 5 intended to remove the receiving device from the mixer 6 (in fact, in the case of removal, the holding stop 9.6 is blocked against the movable element 50.1). In this respect, 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 in the holding position in the vicinity, preferably less than 2 mm.

[0240] exist Fig. 10A , 10BIn one embodiment shown in FIG. 10C, the movable element 50.1 is a wheel movable about a wheel rotation axis 50.2, referred to as a retaining wheel. The wheel 50.1 has at least two different radii, wherein the smallest radius is configured not to extend into the receiving housing 32 in the insertion position, and the largest radius is configured to extend into the receiving housing 32 in the retaining position to abut against the retaining stop 9.6 during removal.

[0241] Preferably, the wheel 50.1 is circular with a flat portion that allows for insertion into position.

[0242] The wheel 50.1 is mounted on a shaft extending along the wheel rotation axis 50.2. The shaft comprises a gear 51 or pulley connected to at least another gear or another pulley 51.1.

[0243] Alternatively, the movable element 50 . 1 is movable in translation, for example by a rack and pinion system by means of the gear 51 .

[0244] The coupling mechanism 52 has the function of establishing a sealed connection between the first and second capsules 3 , 4 and ensures that these capsules remain nested via their connection end pieces 3 . 4 , 4 . 4 by pressing the coupling button 9 . 8 of the second protective shell 9 .

[0245] The coupling mechanism 52 is movably mounted relative to the support 31 between an insertion position and a coupling position. In the insertion position, the coupling mechanism 52 allows insertion and removal of the receiving device 5. In the coupling position, the coupling mechanism 52 locks the first and second capsules 3,4.

[0246] The coupling mechanism 52 comprises a coupling element 52.1 movable between the two aforementioned positions, which in the coupling position extends into the receiving housing 32. In particular, in the coupling position, the coupling element 52.1 cooperates with a coupling button 9.8 movable in the second receiving portion 14. In this respect, when the receiving device 5 is placed in the mixer 6, the coupling element 52.1 and the coupling button 9.8 are positioned facing each other.

[0247] exist Fig. 10A , 10B In one embodiment shown in FIG. 10C, the coupling element 52.1 is a wheel movable about a wheel rotation axis 52.2, referred to as a coupling wheel, which preferably coincides with the wheel rotation axis 50.2. The wheel 52.1 has at least two different radii, wherein the smallest radius is configured not to extend into the receiving housing 32 in the inserted position, and the largest radius is configured to extend into the receiving housing 32 in the coupled position to contact and press the coupling button 9.8.

[0248] The wheel 52.1 is preferably oval in shape in plane.

[0249] The wheel 52.1 is mounted on a shaft extending along the wheel rotation axis 52.2. The shaft comprises a gear or pulley connected to at least another gear or another pulley 51.1. The shaft and gear are preferably identical to the shaft and gear 51. In this way, a first subassembly fixed in rotation is obtained.

[0250] Alternatively, the coupling element 52 . 1 is translationally movable, for example by a rack and pinion system by means of the gear wheel 51 .

[0251] The coupling mechanism 52 is different from the actuation system 35. This results in a different position (eg at a different height) in the mixer 6. Similarly, the receiving device 5 comprises a number of pressing points 8.3, 9.3 which are different from the coupling button 9.8.

[0252] The clamping mechanism 54 has the function of blocking the outlet channel 3.5 of the first capsule 3 while the mixing method is in progress. In fact, the pressure inside the first capsule 3 or the second capsule 4 may lead to an undesired release of the cream. In this case, the cream would overflow into the mixer 6, which is to be avoided. Fig.11A , 11B , as shown in 11C.

[0253] The clamping mechanism 54 is movable between an insertion position and a clamping position relative to the support 31. In the insertion position, the clamping mechanism 54 allows insertion and removal of the receiving device 5 carrying the first capsule 3. In the clamping position, the clamping mechanism 54 clamps the outlet channel 3.5.

[0254] The clamping mechanism 54 comprises a clamping wheel 54 . 1 , referred to as a clamping wheel, which is rotatably movable about a clamping wheel axis 54 . 2 .

[0255] The mixer 6 also comprises a fixed guide wall 54.3 (fixed to the support 31 or even formed integrally therewith) against which the clamping wheel 54.1 rolls or slides, and a clamping wall against which the clamping wheel is clamped in the clamping position. The clamping wall is advantageously part of the guide wall 54.3. There are several variants: one in which the clamping wheel 54.1 approaches the guide wall 54.3 in the direction of the clamping position, one in which the distance is constant or one in which the clamping wall has a specific recess to catch the clamping wheel 54.1 (this may be due to a clamping wheel 54.1 that is movable in translation, see below).

[0256] The teeth 54.11 present on the clamping wheel 54.1 (in fact, the wheel comprises a circular or substantially circular portion that clamps the first capsule 3, and preferably a toothed portion below the circular portion) can cooperate with the teeth 54.31 of the guide wall 54.3, so that the clamping wheel 54.1 rolls against the guide wall 54.3. Moreover, thanks to the teeth 54.11, 54.31, the clamping wheel 54.1 has a rolling movement without sliding against the guide wall 54.3, which allows to avoid sliding that risks erroneously clamping the outlet channel 3.5. Finally, thanks to the teeth 54.11, 54.31, the distance between the clamping wheel 54.1 (except for the teeth, i.e. the average distance) and the guide wall 54.3 can be reduced to almost zero below the first capsule 3, while maintaining a rolling movement against the guide wall 54.3.

[0257] In order to achieve this movement, the clamping wheel 54.1 is mounted, preferably movably rotatably mounted, on an arm 54.5, which itself is rotatably movable about an arm rotation axis 54.51.

[0258] The arm 54.5 is fixed to a gear (or pulley) or gear portion 54.52, which itself is connected to the common gear 40.1 through various gears or pulleys. Therefore, the arm 54.5 is driven in rotation by the same auxiliary motor 40.

[0259] In order to ensure clamping in the clamping position, including when the auxiliary motor 40 is no longer energized, the clamping wheel 54.1 is movably mounted to translate radially along the arm 54.5. A reset device 54.4 arranged between the clamping wheel 54.1 and the arm 54.5 tends to move the clamping wheel 54.1 away from the arm rotation axis 54.51 and thus presses the clamping wheel 54.1 against the guide wall 54.3. More specifically, an intermediate support is provided, which carries the rotation axis 54.2 of the clamping wheel 54.1. The intermediate support is movable in translation relative to the shaft 54.5. A sliding connection with a pin 54.42 in the intermediate support, which slides in a groove 54.53 of the shaft 54.5, allows guiding the translation and also advantageously limits the translational movement.

[0260] Therefore, the reset device 54.4 works under compression, and they are not compressed (or compressed very little) by default. Helical springs, leaf springs or other types of springs are also suitable.

[0261] Due to the resetting device 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 (it can gradually decrease towards the area where the outlet channel 3.5 is located).

[0262] Public Drive

[0263] Preferably, the holding mechanism 50 , the coupling mechanism 52 , and the clamping mechanism 54 are concomitantly driven by a common drive, as described according to the following exemplary embodiment.

[0264] The holding mechanism 50 is driven by a gear 51 coupled to at least another gear 51.1 ( Fig. 10A , 10B ).

[0265] The coupling mechanism 52 is driven by a gear coupled to at least one other gear, preferably the gear 51 and another gear 51.1 ( Fig. 10A , 10B ).

[0266] The clamping mechanism 54 is driven by the gear portion 54 , 52 .

[0267] Different kinematic chains can be provided, but preferably a common pinion 40.1 is provided, which then drives the further gear 51.1 and the gear section 54.52.

[0268] like Fig.11A , 11B , 11C, the common gear 40.1 is located on the output shaft of the auxiliary motor 40. It meshes directly with a gear 51.1 mounted on a shaft including another gear 51.2. A portion of this gear 51.2 meshes with a gear portion 54.52. Thus, the kinematic chain is very simple, with a minimum of gears, and therefore with minimum friction losses, minimum risk of breakage, and with very little play.

[0269] At least two of the three aforementioned mechanisms 50, 52, 54 are simultaneously in the insertion position or the holding, coupling and clamping position, respectively, due to this common gear 40.1 located on the output shaft of the auxiliary motor 40. Thus, the same auxiliary motor 40 drives all three mechanisms, which constitutes a major simplification of the mixer 6 and its operating logic.

[0270] Audio-visual display

[0271] The mixer 6 advantageously comprises a screen 60 and / or a loudspeaker which allows the exchange of information with the user ( Figure 1A , 1B , 7).

[0272] The screen 60 is preferably a touch screen to avoid providing physical buttons. It allows the user to indicate the start and removal time of the cycle. The screen 60 can also display the end of the cycle, for example by being accompanied by an audible warning.

[0273] Power supply and monitoring unit

[0274] According to one embodiment of the present invention, the mixer 6 further comprises a power source (not shown in the figure), which is configured to supply power to the mixer 6, in particular to the drive motor 39 and the auxiliary motor 40. The power source advantageously or even exclusively comprises at least one rechargeable battery 44 ( Figure 7B ). In the example shown, the rechargeable battery 44 advantageously consists of a two-cell lithium-ion battery providing a nominal output voltage of 7.4V.

[0275] like Fig.12 As shown, the mixer 6 also comprises a monitoring unit 45, which comprises, for example, a controller such as a microcontroller or a processor 45.1 such as a microprocessor, which is configured to monitor the operation of the manufacturing device 2, and more specifically the operation of the drive motor 39, the auxiliary motor 40, the heating element 46, the temperature sensor and the screen 60 (for which the processor is preferred) and any audio or video devices. The monitoring unit 45 advantageously comprises a memory 45.2 of non-volatile type, which stores instruction lines in the form of a program to be executed by the controller or processor 45.1, in particular to implement some of the steps described in the following method.

[0276] Other embodiments

[0277] In a variant, the receiving device 5 is integrated into the mixer 6. It is therefore sufficient to insert the first or second capsule 3, 4 into the first or second receiving location 13, 14. A receiving housing 32 is defined, which corresponds to the volume occupied by the receiving device 5.

[0278] Furthermore, in this variant, the actuation surface 8 . 1 , 9 . 1 may not be present: in this case, the actuation member 37 , 38 presses directly on the first or second capsule 3 , 4 .

[0279] How to use

[0280] At least one manufacturing method for manufacturing a composition such as a cosmetic product using the manufacturing device 2 will now be described. The manufacturing method may consist of several sub-methods (referred to as "methods" for clarity), one or more of which will be described. In particular, it is divided into a preparatory method Ep, an initial method Ei, a mixing method Em, and then a removal method Er.

[0281] In particular, these methods (or their variants) are advantageously implemented using the different embodiments of the above-described manufacturing device 2. Preferably, most of the steps of methods Ei, Em and Er are stored in a memory 45.2 of non-volatile type in the form of instructions in lines of code executable by the processor 45.1.

[0282] The preparation method Ep comprises a preparation step Ep1 for any use of the manufacturing device 2, which consists in plugging it into the mains or recharging the battery 44. In addition, this preparation step Ep1 may be preceded or followed by a step Ep2 of positioning the manufacturing device 2 on a flat support, possibly with a power-on step.

[0283] Then, the initialization method Ei is executed. In a step Ei1 ("receiving step"), the processor of the manufacturing machine 2 receives a start instruction. This start instruction is usually generated by a user action (contact with the touch screen 60, a button, a switch, etc.).

[0284] After this step Ei1, in a step Ei2 ("verification step"), the method ensures that the actuation system 35 is in a neutral position, allowing the insertion of the receiving device 5 or of the first and second capsules 3, 4. Generally, it must be ensured that the actuation system 35 does not obstruct the receiving housing 32 (for the insertion of the receiving device 5) or the first or second receiving position 13, 14 (for the insertion of the first or second capsule 3, 4 in the absence of the receiving device 5). In this step Ei2, it should also be verified that the clamping mechanism 54, the coupling mechanism 52 and the retaining mechanism 50 are deactivated, i.e. in their respective insertion positions.

[0285] After this step Ei2 , the receiving means 5 housing the first or second capsule 3 , 4 can be inserted manually into the receiving housing 32 , or even directly into the receiving housing.

[0286] Finally, in the following step Ei3 ("closing step"), at least one of the following is activated: the clamping mechanism 54, the connecting mechanism 52, the retaining mechanism 50, i.e. they are moved. This step Ei3 comprises, for example, instructions for the processor for the auxiliary motor 40 to trigger it so that it drives the three aforementioned mechanisms, all of which are coupled to a common gear (or pulley) 40.1. The auxiliary motor 40 switches from a first position to a second position, so that the clamping mechanism 52, the connecting mechanism 54 and the retaining mechanism 50 switch from their respective insertion positions to their respective clamping, coupling and retaining positions. Preferably, the auxiliary motor 40 remains in the second position at the end of step Ei3, even if it is no longer powered.

[0287] Steps Ei1, Ei2 and Ei3 are specifically performed by the processor 45.1.

[0288] At the end of this initialization method Ei, the mixer 6 is ready to start working on the first and second capsules 3 , 4 : it is the purpose of the mixing method EmEr and the removal method Er.

[0289] The hybrid method Em comprises a first preparatory stage step Em1 ("preparatory step for setting the movement of the actuation system"), in which the connection weld of the capsule farthest from the heating element 46 (the second capsule 4 in the figure) is broken, and the capsule is compressed so that its content is partially transferred toward the capsule closest to the heating element 46. According to the exemplary embodiment shown, the movement of the second actuation member 38 is set to break the connection weld of the second capsule 4 (which contains, for example, an oil phase preparation). In this way, a part of the content of the second capsule 4 is sent to one side of the first capsule 3, in particular to the connection channel 3.3 (because the connection weld of the first capsule 3 has not yet been broken). The second actuation member 38 is preferably set to move along its actuation stroke C38. In order to simplify the design, the second actuation member 38 does not have to have a partial stroke sensor.

[0290] In the preparatory stage step Em2 ("second step of setting the movement of the actuation system" or "prestressing step"), the first actuation member 37 is set to move along a partial stroke strictly below its actuation stroke C37 and to maintain its position, so as to exert a prestress on the first capsule 3 (which comprises, for example, an aqueous formulation) so that the plane 3.7 is pressed against the diffuser plate 46.2. This prestressing allows to promote the heat exchange between the diffuser plate 46.2 and the first capsule 3 during the subsequent step Em3 ("heating step"). It should be noted that, by setting the first actuation member 37 to move over a partial stroke, the pressurization of the diffuser plate 46.2 by the first capsule 3 is achieved without causing failure of the connecting weld in the first capsule 3 (which would cause the formulation to be sent from the first capsule 3 to the second capsule 4).

[0291] In the preparatory phase step Em3 ("heating step"), the heater element 46 is activated to generate heat for the first capsule 3. Since the heater element 46 is located on one side of the plane 3.7 of the first capsule 3 and the prestressing step has allowed good thermal contact between the diffuser plate 46.2 and the first capsule 3, the heat provided by the heater element 46 is well distributed over the contents of the first capsule 3. Step Em3 is therefore activated without any movement of the actuating members 37, 38. This stirring-free heating step is particularly advantageous because it does not degrade the quality of the preparation. Stirring during this heating step would in particular risk degrading the properties of the emulsion obtained by mixing the preparation. During the preparatory phase step Em3, the temperature of the heater element 46 reaches a target temperature Tc comprised between 80°C and 90°C. The purpose of this target temperature Tc is that the contents of the first capsule 3 reach a target temperature Tc' also comprised between 80°C and 90°C, and preferably of the order of 85°C. In practice, it was found that the temperature of the contents of the first capsule 3 during this heating step Em3 corresponds substantially to the target temperature Tc of the heater element 46, but with a slight time offset.

[0292] Then, in the stirring phase step Em3' ("mixing step"), the heater element 46 is deactivated and the first actuating member 37 is then moved along its rated stroke to break the connecting weld in the first capsule 3. Cutting off the power supply to the heater element 46 before the activation of the first actuating member 37 allows all the power provided by the power supply to be available for powering the drive motor 39. This characteristic is particularly advantageous in the case where the mixer 6 is powered by an electric transformer or a low-power battery 44. In fact, this allows preventing the power supplied to the drive motor 39 from being insufficient to allow the failure of the connecting weld of the first capsule 3 (which would then lead to a blockage of the device), the connecting weld failure step requiring a high motor torque. When the first actuating member 37 reaches the end of its actuation stroke C37, the content of the first capsule 3 is delivered to the second capsule 4, and then the two formulations can circulate freely from the first or second capsule 3, 4 to the other second or first capsule 4, 3 via the connection 3.2, 4.2 in each reciprocating movement of the actuating system 35, the connecting weld initially present in each of the first and second capsules 3, 4 having been broken.

[0293] Subsequently, steps Em4, Em5, Em6 are successive stirring steps, with or without heating (this is called the stirring phase).

[0294] The stirring phase step Em4 ("stirring step without heating") consists in setting the actuating members 37, 38 to reciprocate without activating the heater element 46, i.e. without heating. In this step, the first and second capsules 3, 4 are each deformed at least once. According to one embodiment, step Em4 lasts at least 1.4 s, preferably between 2 s and 4 s. This stirring step without heating allows the drive motor 39 to be started at a constant speed while benefiting from the full power of the power supply.

[0295] Steps Em1, Em2 and Em3, Em3', Em4 alternate between setting the actuation system 35 in motion and heating with the heater element 46. This results in the power being dedicated to the actuation system 35 or to the heater element 46. This exclusive alternation allows the battery 44 to be saved by dispersing the high-power moments. In fact, the engagement of the setting motion generates a significant resisting torque, which exerts a significant motor torque, and the temperature rise also requires significant power: the battery 44 is then highly loaded. This alternative also allows the size of the components to be reduced, which is a design constraint during the manufacture of portable and battery-powered mixers.

[0296] On the other hand, once the temperature approaches the target temperature Tc′ and once the actuation system 35 is already in motion, the load on the battery 44 decreases and the heater element 46 and the actuation system 35 are powered in parallel: this is the objective of step Em5 .

[0297] In the stirring phase step Em5 ("stirring and heating step"), the drive system 35 remains enabled and the heater element 46 is reactivated to keep the mixture of the formulation at a temperature preferably at the target temperature Tc'. The heater element is thus maintained at the target temperature Tc. This step Em5 lasts, for example, from 5s to 30s, preferably from 7s to 15s. Although the load on the battery 44 is less than that of engagement or temperature rise, it may have a tendency to discharge rapidly during this phase, so the duration of this phase is limited.

[0298] However, this step Em5 is long enough to allow the first and second capsules 3, 4 to deform several times each and to allow the emulsion obtained by mixing the formulation to be satisfactory.

[0299] Between steps Em4 and Em5 , the actuation system 35 is not interrupted.

[0300] Then, a stirring phase step Em6 is carried out ("cooling stirring step"). Alternatively, this step is carried out without stirring, but preferably keeping the actuation system 35 enabled to improve or maintain the homogenization of the preparation. During step Em6, the temperature of the cream is reduced to a take-off temperature Tr' comprised between 35°C and 48°C, preferably between 38°C and 42°C. In the case of the embodiment shown, the take-off temperature Tr' of the cream corresponds to the take-off temperature Tr of the heater element 46 comprised between 55°C and 60°C. This temperature deviation between the contents of the first and second capsules 3, 4 and the temperature of the heater element 46 during the cooling step is explained in particular by the fact that, during stirring, the composition is present in the first capsule 3 only part of the time and is therefore facing the diffuser plate 46.2 at the level at which the temperature measurement is carried out.

[0301] The simplest cooling technique is to stop the power supply to the heater element 46 and allow the cream to cool with room temperature air. Therefore, the duration of step Em6 actually depends on the room temperature. In this regard, the temperature sensor is advantageously located in the mixer 6, more specifically in the receiving device 5. In order to limit the number of temperature sensors, it is the same sensor that measures the temperature of the heater element 46.

[0302] As in the embodiment shown, the temperature sensor measures the temperature of the heater element 46 , the same sensor being repeatedly used: this means that the end of step Em6 is determined by the temperature measured by said sensor, ie a take-off temperature Tr′ comprised between 55°C and 60°C.

[0303] Once the removal temperature is reached, the actuation system 35 is deactivated.

[0304] The cooling step Em6 usually lasts at least 20 s, preferably 40 s.

[0305] In a variant, step Em6 may also advantageously include a minimum stirring duration, for example of about 40 s, to ensure a good emulsion, followed by an additional stirring duration that occurs only when the removal temperature Tr' has not yet been reached. In other words, stirring is performed for a certain period of time even below the removal temperature Tr'.

[0306] It should be noted that according to one embodiment, the mixer 6 (not shown) may include a cooling system for actively cooling the cream and accelerating the process. For example, in addition to the cooling element, the cooling system may be provided with a small fan that forces air to circulate in the mixer 6, thus forcing convection cooling.

[0307] Once the mixing method Em is completed, the removal method Er can be used. This removal method Er will now be described.

[0308] Since the preceding steps take some time (usually more than a minute), the user may not be near the mixer 6 but may be carrying out his usual activities (eating breakfast, listening to the radio, watching TV, buttering bread, getting dressed, ironing clothes, etc.). It is therefore important that the mixer 6 is able to keep the cream ready for use for a predetermined period of time.

[0309] To this end, in step Er1 ("transfer to storage step"), the actuation system 35 is activated once to transfer the cream into the capsule (ie here the first capsule 3) situated on the side of the heating element 46. This step is optional if step Em6 has already stopped in the correct configuration.

[0310] In step Er2 ("prestress maintenance step"), the actuation system 35 returns to the prestressed position, wherein the first actuation member 37 exerts a prestress on the first capsule 3 to press it against the diffuser plate 46.2, and then, in step Er3 ("temperature maintenance step"), the heater element 46 is restarted to maintain the cream at the removal temperature Tr'. The prestress maintenance step Er2 allows better heat conduction, similar to step Em2. Preferably, stirring or movement of the drive system 35 is performed periodically during step Er3 to ensure a good emulsion, which may be partially deteriorated by the presence of hot spots on the diffuser plate 46.2.

[0311] In a variant, the removal method may comprise, instead of step Er2, a step Er2' ("neutral position maintenance step"), in which the actuation system 35 is activated to place in an intermediate position, i.e. without stressing the first capsule 3 or the second capsule 4, and in particular without stressing the first capsule 3 against the heating element 46. Surprisingly, this variant allows a better emulsion to be maintained and avoids having to resort to periodic stirring during the holding phase.

[0312] Step Er3 is performed during a predetermined waiting time, which is less than 15 minutes so as not to power the heater element 46 for too long, but greater than 1 minute and preferably about 5 minutes so as to allow the user flexibility in time management in the morning.

[0313] In other words, this means that after the movement of the actuation system 35 is ended, the user has between 1 minute and 15 minutes, and preferably about 5 minutes (depending on the factory setting or the user setting), to collect the cream at the right temperature.

[0314] Once the user is ready to use the cream, he touches the touch screen or presses a button, which triggers step Er4 (“step of receiving a removal instruction”), during which the mixer 6 receives a removal instruction.

[0315] Then, in step Er5 (“step of setting the neutral position”), the actuation system 35 is activated to be set in the neutral position.

[0316] In the case of the actuation system 35 being prestressed at the level of the first actuation member 37, the first actuation member must complete its movement, which causes the displacement of the formulation in the second capsule 4, and then the actuation system 35 stops in a neutral position corresponding to a position suitable for removing the receiving device 5. This position also corresponds to a starting position suitable for implementing the next manufacturing cycle implementing the above-described method. In fact, once the drive motor 39 is started, the second actuation member 38 is ready to compress the second capsule 4 during step Em1.

[0317] In a variant where the actuation system 35 has been set in an intermediate position during the temperature maintenance step Er2' of step Er3, it may be necessary that the actuation system 35 must reciprocate to be positioned in a neutral position to implement the next manufacturing cycle of the above method, i.e., the second actuation member 38 is ready to compress the second capsule 4 during step Em1.

[0318] During this reciprocating movement of the actuation system 35 , the cream present in the first capsule 3 is partly conveyed into the second capsule.

[0319] Finally, in a final step Er6 (“unlocking step”), each mechanism activated in step Ei3 is placed in the insertion position. Likewise, this step Er6 comprises the activation of the auxiliary motor 40 .

[0320] Subsequently, the user grabs the receiving device 5 and removes it from its receiving housing 32. The user then presses the actuation surfaces 8.1, 9.1 to pivot the blades in order to discharge the cream present in the first capsule 3 and the second capsule 4 via the outlet channel 3.5 of the first capsule 3. Finally, it is sufficient to remove the first capsule 3 or the second capsule 4 from the receiving device 5 so that the latter is ready for use again. In fact, no part of the mixer 6 (production device 2 or receiving device) comes into contact with the preparation.

[0321] As can be seen from the above description, all or part of the steps of the method are controlled relative to a reference temperature. This reference temperature is usually monitored using the above-mentioned temperature sensor, which allows the temperature prevailing inside the capsule to be determined. In particular for a basic recipe where all characteristics are known in advance and a specific composition to be achieved, it is also conceivable to have a timed cycle, i.e. where only the cycle time is followed, rather than the temperature evolution.

[0322] Therefore, the different steps for implementing the above method are as follows, which steps can be performed continuously, for example:

[0332] Em6: a step of stirring and cooling and not heating (cooling) to a take-out temperature (implemented by a mixer including a processor for controlling a drive motor),
