Description

Technical Field

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

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

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

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

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

[0006] The mixer includes in particular:

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

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

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

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

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

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

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

[0014] The present invention aims to solve some or all of these problems. The technical problem underlying the present invention is therefore to provide a device for producing a composite that is simple, compact and easy to manufacture, while having a simple and cost-reduced structure.

[0082] Figure 1A and Figure 1B A manufacturing apparatus 2 according to a first embodiment of the present invention is shown. The manufacturing apparatus is configured to manufacture a composition, such as a beauty product, a hair care product, a medicinal product, a disinfectant product, a maintenance product, a cleaning product, or an agricultural product. When the composition to be manufactured is a beauty product, the beauty product may be, for example, a homogeneous emulsion, a homogeneous solution, or a mixture of multiple soluble phases.

[0083] The manufacturing device 2 is intended for primarily personal use and is small in size: it allows the manufacturing of a single portion ready for use. Therefore, its dimensions should meet the volume constraints of bathrooms, beauty salons, luggage (for transport), etc. Therefore, the manufacturing device 2 does not have a dimension greater than 40 cm.

[0084] The manufacturing device 2 includes a receiving mechanism configured to receive first and second capsules 3, 4, also referred to as tablets or packaging units, each comprising a predetermined amount of a first preparation and a predetermined amount of a second preparation, and a mixer 6 configured to mix the first and second preparations contained in the first and second capsules 3, 4 received in the manufacturing device 2 in order to obtain a cosmetic product.

[0085] The mixer 6 comprises a housing which is part of the receiving mechanism and is arranged to receive the first and second capsules 3 , 4 directly or via specific receiving means 5 .

[0086] In the preferred and especially in the attached Figure 1A , 1B, 7A, 8A, 8B, 8C, the mixer 6 comprises a housing 32 capable of removably receiving the receiving device 5. In this case, the housing 32 has a shape that is substantially complementary to that of the receiving device 5.

[0087] The mixer 6 also comprises an actuation system 35 configured to exert a force on the first and second capsules 3 , 4 , if necessary via the containment device 5 , so as to allow mixing and stirring of the composition to be manufactured.

[0088] The receiving device 5 is also referred to as a shuttle (because it serves as a carrier for the first and second capsules 3, 4) and preferably has a relatively symmetrical shape, such as a parallelepipedal or an elliptical / oval shape. A longitudinal direction X can be defined for the receiving device, corresponding to the direction along which the receiving device is inserted into the receiving portion 32. Thus, when the receiving device 5 is inserted into the mixer 6, the longitudinal direction X coincides with the insertion direction.

[0089] Advantageously, the mixer 6 is configured to mix the first and second formulations inside the containment device 5 and preferably inside the first and second capsules 3 , 4 , without any formulation coming into contact with the manufacturing device 2 .

[0090] As indicated further above, some of the embodiments presented here can be used in a production apparatus 2 without a receiving device 5 , ie wherein the first and second capsules 3 , 4 can be positioned directly in the mixer.

[0091] Advantageously, the first formulation is the first phase of the cosmetic product to be manufactured, such as the oil phase of the cosmetic product, and the second formulation is the second phase of the cosmetic product, such as the aqueous phase of the cosmetic product. For example, the oil phase may constitute the matrix of the cosmetic product to be manufactured, and the aqueous phase may include the active ingredient and thus constitute the active complex of the cosmetic product to be manufactured.

[0092] capsule

[0093] Two capsules can be used in the present manufacturing device 2 , which is described in detail in the document filed under application number FR 1 755 744 and whose description of the capsules is incorporated herein.

[0094] Capsules are therefore not the object of the present invention.For the purpose of the following description, the following points will be reviewed.

[0095] More specifically, if Figure 2A , 2B, 3A, 3B, 4A, 4B, the first and second capsules 3, 4 are different from each other and are configured to be fluidically connected to each other. In addition, each of the first and second capsules 3, 4 is advantageously disposable.

[0096] The first capsule 3 includes a first deformable compartment 3.1 having a convex shape, a first connecting portion 3.2, and a first connecting channel 3.3. The first deformable compartment contains a first agent, and the first connecting channel is configured to fluidically connect the first deformable compartment 3.1 and the first connecting portion 3.2. Advantageously, the first connecting channel 3.3 is formed by a first connecting pipe. The first connecting portion 3.2 more specifically includes a female connecting connector 3.4, for example, having a cylindrical shape, which is fluidically connected to the first connecting channel 3.3. The first capsule 3 includes a flat surface 3.7, through which the first connecting portion 3.2 extends.

[0097] The first capsule 3 further includes an output channel 3.5, such as an output conduit, which is fluidically connected to the first connecting channel 3.3 and is equipped with an output hole 3.6. Advantageously, the output channel 3.5 extends in an extension of the first connecting channel 3.3 and is substantially parallel to the first connecting channel 3.3. In this case, the output channel 3.5 can be mounted indiscriminately on either the first capsule 3 or the second capsule 4. In fact, the output channel 3.5 is only required to operate when the manufacturing device 2 is in use.

[0098] The second capsule 4 includes a second deformable compartment 4.1 having a convex shape, a second connecting portion 4.2, which contains a second agent, and a second connecting channel 4.3, the second deformable compartment being configured to be connected to the first connecting portion 3.2, the second connecting channel being configured to fluidically connect the second deformable compartment 4.1 and the second connecting portion 4.2. Advantageously, the second connecting channel 4.3 is formed by a second connecting conduit, and the second connecting portion 4.2 extends approximately perpendicularly relative to the second connecting channel 4.3. The second connecting portion 4.2 more specifically includes a male connecting connector 4.4, for example, of cylindrical shape, which is fluidically connected to the second connecting channel 4.3 and is configured to receive the female connecting connector 3.4 in a sealed manner. The second capsule 4 includes a flat surface 4.7, through which the second connecting portion 4.2 passes.

[0099] The first and second capsules 3, 4, and more specifically the first and second deformable compartments 3.1, 4.1, are each closed by a connecting solder that ensures the leak-tightness of the first and second capsules 3, 4, and that is brittle upon reaching a pressure threshold. These pressure thresholds can be reached in the mixer 6. These connecting solders are further described in detail in the document filed under application number FR1755744.

[0100] Each of the first and second capsules 3, 4 is configured to contain a mixture of a predetermined amount of the first agent and a predetermined amount of the second agent in its entirety or substantially in its entirety. To this end, the deformable compartment is flexible and may be provided with a cushioning area. This is more precisely described in the document filed under application number FR1755744.

[0101] Storage device

[0102] More specifically, if Figure 2A , 2B, 3A, 3B, 4A, 4B and 5, the receiving device 5 can occupy an open position and a closed position, in which the first and second capsules 3, 4 can be introduced into the receiving device 5, and in which the closed position the receiving device 5 can hold the first and second capsules 3, 4 in place.

[0103] The storage device 5 is more specifically a storage box 7 ( Figure 2A , 2B), the storage box is configured to at least partially store and accommodate the first and second capsules 3, 4. The storage device 5 particularly includes a first protective shell 8 and a second protective shell 9, which are arranged in a first position (see Figure 2A , 2B, 5) and the second position ( Figure 4A , 4B) are hingedly mounted relative to each other, the first position corresponding to the open position of the storage device 5, and the second position corresponding to the closed position of the storage device 5. The storage device 5 also includes a first support portion 11 and a second support portion 12 arranged in the storage box 7. The first and second support portions 11, 12 respectively include a first storage position 13 and a second storage position 14, the first storage position being configured to store the first capsule 3, and the second storage position being configured to store the second capsule 4. The first and second protective shells 8, 9 each include an opening 8.2, 9.2 for allowing access to the first or second storage position 13, 14. These openings 8.2, 9.2 define an insertion surface of the storage device 5. The storage device 5 includes a removal surface opposite to the insertion surface.

[0104] Advantageously, the first support portion 11 comprises a receiving pad 15 configured to receive the peripheral portion of the capsule 3, and the second support portion 12 also comprises a receiving pad 15 configured to receive the peripheral portion of the second capsule 4. These receiving pads 15 partially define the first and second receiving locations 13,14.

[0105] The first supporting portion 11 comprises a first resting surface 11 . 1 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 .

[0106] In the same way, 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. The second resting surface 12 . 1 thus partially defines the second receiving location 14 .

[0107] When the first and second capsules 3, 4 are inserted, their respective flat faces 3.7, 4.7 are turned towards each other and have two resting surfaces 11.1, 12.1 between them.

[0108] In order to allow the passage of the first and second connecting portions 3.2, 4.2 of the first and second capsules 3, 4, the first and second seating surfaces 11.1, 12.1 each comprise a through opening 11.2, 12.2 in the form of a cutout and extending along the insertion axis X( Figure 1A ) opens outward.

[0109] The storage device 5 further comprises a partition wall 22 defining a partition surface ( Figure 3A , 3B). A partition wall 22 is located between the first and second storage locations 13, 14. Furthermore, the partition wall is integrally connected to the first support portion 11. The partition wall 22 includes a through-opening 22.2 to allow the first and second connecting portions 3.2, 4.2 to be positioned within the storage device. The through-opening 22.2 is in the form of a through-cut in the thickness and is open to the outside.

[0110] The openings 11 . 2 , 22 . 2 , 12 . 2 thus form a space for receiving the connecting joints 3 . 4 , 4 . 4 of the first and second capsules 3 , 4 .

[0111] Furthermore, a first actuation surface 8 . 1 comprising the first shell 8 and the first support portion 11 and a second actuation surface 9 . 1 comprising the second shell 9 and the second support portion 12 are defined.

[0112] Each actuation surface 8.1, 9.1 participates in the transmission of the force received by the receiving means 5 towards the first and second capsules 3, 4. This will be explained in detail below.

[0113] Articulated

[0114] According to Figure 2A , 2B, 3A, 3B, 5 can be seen in the embodiment, the first and second shells 8, 9 around the hinge axis 10 and in the storage position (see Figure 2A , 2B, 3A, 3B) and connection position (see Figure 4A, 4B) are hinged relative to each other. In the stored position, the first and second shells 8, 9 are separated from each other, and the first and second capsules 3, 4 can be stored in the first and second stored positions 13, 14, respectively. In the connected position, the first and second shells 8, 9 are close to each other, and the first and second capsules 3, 4 are pre-connected to each other. Pre-connected to each other means that the male connection connector 4.4 of the second capsule 4 is partially inserted into the female connection connector 3.4 of the first capsule 3, without establishing a sealed connection between the first and second capsules 3, 4.

[0115] When the first and second shells 8, 9 are in the stowed position, the first and second shells 8, 9 may have an inclination angle of, for example, greater than or equal to 7°, and for example, approximately 7°. When the first and second shells 8, 9 are in the connected position, the first and second shells 8, 9 are substantially parallel to each other. More specifically, there are two main components that are 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.

[0116] Advantageously, the first and second shells 8, 9 (or the actuating surfaces 8.1, 9.1) are configured to insert the first connection portion 3.2 into the second connection portion 4.2 when the receiving device 5 is moved to the closed position. In fact, when the first and second shells 8, 9 are in the closed position, the connection portions 3.2, 4.2 partially nest in each other.

[0117] The first and second support portions 11, 12 are more particularly configured such that when the first and second shells 8, 9 are in the connected position, the first and second capsules 3, 4 extend substantially parallel to each other. Figure 4A 4B , when the first capsule 3 is received in the receiving device 5 and the receiving device 5 is in the closed position, the first capsule 3 is configured to partially extend outside the receiving device 5. Advantageously, when the first capsule 3 is received in the receiving device 5 and the receiving device 5 is in the closed position, the output hole 3.6 is configured to extend outside the receiving device 5.

[0118] Heating element

[0119] Manufacturing equipment 2 includes Figure 3A , the heating element 46 visible in 3B. In the embodiment depicted in the figures, the heating element 46 is part of the receiving device 5. However, in the absence of a receiving device 5, the heating element can be integrated with the mixer.

[0120] The heating element 46 is fixed to the partition wall 22. In the design, the heating element 46 has been selected to be on the first support portion 11 side, which means that the heating element 46 is installed on the side of the partition wall 22 on the first support portion 11 side.

[0121] The heating element 46 preferably comprises one or more heating resistors 46.1 and a diffusion plate 46.2. The heating element 46 therefore has a flat shape in order to better diffuse the heat and, if possible, has a width of at least 500 mm. 2 and preferably about 800 mm 2 area.

[0122] However, since the first support portion 11 is located between the first capsule 3 and the heating element 46 , a communication opening 46 . 3 is provided in the first support portion 11 , which directly connects the flat surface 3 . 7 of the first capsule 3 with the heating element 46 (ie, separated only by air).

[0123] Electrical contact tracks for heating elements

[0124] The heating element 46 needs to be powered. Preferably, the container 5 does not comprise its own battery and should be powered when the container is inserted into the receptacle 32.

[0125] Thus, an electrical connection is provided between the container 5 and the mixer 6 .

[0126] The receiving device 5 includes an insertion surface and a removal surface, wherein the openings 8.2, 9.2 are located on the insertion surface and are the surface that first enters the receiving portion 32, and the removal surface is opposite to the insertion surface and is the surface that is visible when the receiving device 5 is inserted into the receiving portion 32. The receiving device 5 also includes a first actuation surface 8.1 and a second actuation surface 9.1 that are opposite to each other.

[0127] Finally, the receiving device 5 comprises a first connection surface 23 and a second connection surface 24, which are preferably opposite to each other. Figure 2A In the embodiments shown in Figures 2B, 3A, 3B, 4A, 4B, the connection faces 23 and 24 correspond to the side faces of the heating element 46 and are therefore distinct from the first and second actuation faces 8.1, 9.1 and the insertion / removal face.

[0128] The connecting surfaces 23, 24 extend between the actuating surfaces 8.1, 9.1 of the receiving device 5. Preferably, the connecting surfaces 23, 24 connect the actuating surfaces 8.1, 9.1 of the receiving device 5, ie they are adjacent.

[0129] The general shape of the receiving device 5 is chosen so that the connection surfaces 23, 24 are further apart than the actuation surfaces 8.1, 9.1 (and thus the insertion / removal surface). On the other hand, if a minimal parallelepiped were used into which the receiving device 5 could be inserted, the surfaces contacting the connection surfaces 23, 24 would be further apart than the surfaces contacting the actuation surfaces 8.1, 9.1 and closer together than the surfaces contacting the insertion / removal surface. This is due to the fact that the receiving device is wider than it is thick (and, in addition, taller than it is wide).

[0130] The first connection surface 23 comprises a first electrical contact track 23.1 for supplying power to the heating element 46, and the second connection surface 24 comprises a second electrical contact track 24.1 also for supplying power to the heating element 46 ( Figure 2A , 3A, 3B, 4A, 4B). The electrical contact rails 23.1, 24.1 are therefore outside the receiving device 5 in order to make contact with the complementary rails ( Figure 2A , 4A, 4B).

[0131] This configuration has several advantages: First, it ensures a simple and effective electrical connection. It also avoids the risk of short circuits. In fact, once liquid flows in the receptacle 32 (for example, water from a shower or sink, or a simply ruptured capsule), it is impossible for both electrical contact rails 23.1, 24.1 to contact the same amount of liquid at the same time.

[0132] The first connecting surface 23 includes the first and second shells 8 , 9 , the first support portion 11 and a portion of the partition wall 22 .

[0133] Specifically, 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 track 23.1 is preferably positioned on the side walls 23.22 of the longitudinal groove 23.2. Figure 3A In the embodiment shown in FIG3B , the bottom 23.21 and the side wall 23.23 are formed by a portion of the first support portion 11. Suitable cutouts 8.5 are therefore provided in the first shell 8 to allow for the longitudinal groove 23.2. The opposing side wall 23.22 is formed by a portion of the partition wall 22. The first electrical contact track 23.1 is therefore positioned on this side wall 23.22 (because the heating element 46 is mounted on the partition wall).

[0134] Likewise, a similar longitudinal groove 24.2 is provided on the second connecting surface 24, which has a cutout 9.5 in the second shell 9 and has a bottom 24.21 and two opposing side walls 24.22, 24.23. Due to the non-centering of the groove, the cutout 9.5 in the second shell 9 is less pronounced than the cutout 8.5 in the first shell 8.

[0135] The grooves 23.2, 24.2 are configured to engage on respective complementary guide rails 31.1, 31.2 (sliding connection) provided in the housing 32 and on the (preferably opposite) connection sides ( Figure 1A , 7A). Thus, the grooves 23.2, 24.2 form a cutout that extends over the entire height of the portion of the receiving device 5 in which the grooves are located, at least to the insertion height. The complementary guide rails 31.1, 31.2 contribute to defining the housing 32 and are positioned on opposite edges.

[0136] In particular Figure 4A In the embodiment shown in FIG. 4B , the electrical contact tracks 23 . 1 , 24 . 1 are not located in the same horizontal plane, but are offset.

[0137] The electrical contact tracks 23 . 1 , 24 . 1 may take various forms: electrical pins, metal sheets (as shown), etc. The electrical contact tracks 23 . 1 , 24 . 1 are preferably slightly deformable in order to ensure permanent contact when the receiving device 5 is placed in the receptacle 32 .

[0138] Therefore, it is noted that the longitudinal grooves 23.2, 24.2 are not centered relative to the first and second actuation surfaces 8.1, 9.1 (see in particular Figure 2A , 4A, 4B). In terms of design, this is caused by the grooves mainly formed in the first support part 11 and the first protective shell 8.

[0139] The benefit of this asymmetry lies in the positioning function. In fact, it is impossible to place the receiving device 5 in the wrong orientation (rotated 180° around the longitudinal axis X) because the grooves 23.2, 24.2 cannot be inserted into the guide rails 31.1, 31.2 and the second shell 9 abuts against the guide rails 31.1, 31.2.

[0140] To ensure a detent effect during vertical rotation (i.e., when attempting to insert the removal surface first instead of the insertion surface), longitudinal grooves 23.2, 24.2 do not extend over the entire height of the portion of the first or second shell 8, 9 in which they are located. Consequently, no dedicated parts are required; the stop effect is simply achieved by the portion of the first or second shell 8, 9 that is not penetrated by the cutting effect. On the other hand, when the receiving device 5 is in the wrong orientation, the first or second shell 8, 9 prevents the grooves 23.2, 24.2 from being inserted into the guide rails 31.1, 31.2.

[0141] Furthermore, the longitudinal grooves 23.2, 24.2 each comprise an end stop 23.3, 24.4 on the side of the removal surface. These end stops 23.3, 24.4 function as insertion stops in order to define a maximum insertion position in the receiving portion 32.

[0142] In fact, there are two different types of stops, which are located approximately at the same place: at the ends of the longitudinal grooves 23.2, 24.2.

[0143] Electrical contact tracks for temperature sensors

[0144] Because of the heating element 46 for mainly heating the first capsule 3, the first support portion 11 is preferred over the second support portion 12 in order to support the walls 23.23, 24.23 of the recesses 23.2, 24.2.

[0145] In fact, a temperature sensor (not shown in the figures) is connected to the rear face of the diffuser plate 46 . 2 in order to measure the temperature in the vicinity of the first housing location 13 and therefore of the first capsule 3 .

[0146] The temperature sensor is typically a CTN (negative temperature coefficient thermistor).

[0147] The temperature sensor should also be electrically connected to the mixer 6 (and in particular, ultimately to the processor for data collection) and to the battery 44 provided with the mixer 6 to power the temperature sensor. To this end, a first supplementary electrical contact track 46.51 is provided on the first contact surface 23. This first supplementary electrical contact track 46.51 is distinct from the first electrical contact track 23.1. More precisely, the first supplementary electrical contact track 46.41 is provided in the first recess 23.2, on the side wall 23.23, i.e., on the side wall formed by the first support portion 11.

[0148] Similarly, a second supplementary electrical contact track 46 . 52 is arranged in the second groove 24 . 2 .

[0149] The two supplementary electrical contact tracks 46.51, 46.52 are also advantageously offset. In the specific example, the supplementary electrical contact track 46.51 and the electrical contact track 24.1 are on the same level, and the supplementary electrical contact track 46.52 and the electrical contact track 23.1 are on the same level.

[0150] Figure 2A , 3A, 3B, 4A, 4B, 5 show these tracks.

[0151] Positioning unit

[0152] The receiving device 5 comprises a positioning portion 17 for ensuring that the first and second capsules 3, 4 are correctly positioned, that is, the "correct" capsules 3, 4 are placed in the "correct" receiving positions 13, 14 (in the Figure 2A , 5 .) The positioning means 17 are preferably located at the ends of the through openings 11 . 2 , 12 . 2 in order to prevent an unwanted passage of the connection joints 3 . 2 , 4 . 2 .

[0153] The positioning portion 17 comprises at least one door leaf 17.1 which opens towards the outside of the storage device 5 (preferably two door leaves on each side, as shown in the figure; preferably, the two door leaves 17.1 have a bar-like configuration, i.e. are hinged towards the outside of the storage device).

[0154] Specifically, the positioning portion 17 fulfills two different roles.

[0155] The door leaf 17.1 includes an opening 17.2 having a shape complementary to the female connector 3.4 of the first capsule 3, thereby permitting its insertion into the opening 8.2. Furthermore, the door leaf 17.1 includes a stop 17.3 that helps define the opening 17.2, thereby preventing the second connector 4.2, which is laterally longer than the first connector 3.2, from being inserted into the opening 8.2. Indeed, if an attempt is made to insert the second capsule 4 into the first receiving position 13, the end of the second connector 4.2, i.e., a portion of the male connector 4.4, abuts against the stop 17.3.

[0156] For access to the second storage position 14, when the storage device 5 is in the closed position, the detent 17 blocks the second storage position: the passage opening 12.2 is preferably also blocked by the stop 17.3. Conversely, when the storage device 5 is in the open position, that is, when the second shell 9 is rotated on its hinge, the passage opening 12.2 is released.

[0157] Finally, since the door leaf 17 . 1 is open towards the outside, the first and second capsules 3 , 4 are not functionally blocked when they are removed from the receiving device 5 (both at the same time, since they are fixed together).

[0158] Depending on the design of the relative movement of the parts, the positioning portion 17 can be fixed to the first support portion 11 or to the second support portion 12 (as shown in the figures): if the second support portion 12 is fixed to the second shell 9 (and is therefore rotationally movable relative to the first support portion 11), then the positioning portion is preferably fixed to the first support portion 11. In other words, it is indifferent.

[0159] The restoring spring 17 . 4 keeps the positioning portion 17 in the default position, ie the closed position.

[0160] Pressing element-blade

[0161] Especially Figure 2B , 3A, 3B, 5, the storage device 5 also includes a first pressing element 19 and a second pressing element 21, the first pressing element 19 is configured to enter the interior of the second storage position 14, that is, for applying pressure on the first capsule 3 and more specifically on the first deformable compartment 3.1, and the second pressing element 21 is configured to enter the interior of the first storage position 13, that is, for applying pressure on the second capsule 4 and more specifically on the second deformable compartment 4.1.

[0162] The first pressing element 19 (or the second pressing element 21) is preferably mounted on the first supporting portion 11 (or the second supporting portion 12) and is movable between an inactive position, i.e., an unfolded position, and an active position, i.e., a folded position, in which the first or second receiving position 13, 14 is easily accessible to the first or second capsule 3, 4 (see FIG. Figure 2B , 3A, 3B), in this effective position, the first pressing element 19 (or the second pressing element 21) enters the interior of the first storage position 13 (or the second storage position 14), that is, the first pressing element (or the second pressing element) can exert pressure on the first deformable compartment 3.1 of the first capsule 3 (or the second deformable compartment 4.1 of the second capsule 4).

[0163] First pressing element 19 (or second pressing element 21) is advantageously mounted so as to be rotatable about hinge 19.1 (or hinge 21.1). Hinge 19.1 (or hinge 21.1) is located opposite opening 8.2 (or opening 8.1) of first shell 8 (or second shell 9). Hinges 19.1, 21.1 are therefore both located near the removal surface of receiving device 5.

[0164] Each pressing element 19, 21 has a flat inner surface 19.2, 21.2, forming a rotating blade. Each flat inner surface 19.2, 21.2 engages its respective first or second capsule 3, 4. As pressure is applied to the pressing element, the space between the blade and the seating surface 11.1, 12.1 gradually and continuously decreases. When the first or second capsule 3, 4 is installed, the outlet opening 3.6 and the connecting portion 3.2, 4.2 are located on opposite sides of the hinge 10. This allows for efficient expulsion of the cream from the first or second capsule 3, 4, while avoiding any undesirable retention areas within the first or second capsule.

[0165] In order to keep the pressing elements 19, 21 in the default open position (ie when the receiving device 5 is not driven or when the second shell 9 is in the pivoted position), a restoring mechanism 21.3, such as a spring, is arranged to abut against the first or second shell 8, 9 ( Figure 5 ). The restoring mechanism 21.3 may tend to push the blade slightly extended on the other side of the hinge 21.1.

[0166] In use, as will be described later, the two pressing elements 19, 21 are actuated in sequence to allow the cream to be stirred. Thus, the cream is transferred from the first or second capsule 3, 4 to the other second or first capsule 4, 3.

[0167] Preferably, in order to optimize the operation of the blades, the hinge 19.1 (or hinge 21.1) defines an axis of rotation contained in the plane of the resting surface 11.1 (or resting surface 12.1) and perpendicular to the longitudinal axis of the receiving device 5. In the absence of a capsule, the inner faces 19.2, 21.2 can rest against the resting surfaces 11.1, 12.1.

[0168] Likewise, the hinges 19 . 1 , 21 . 1 are preferably located exactly at the end of the first or second storage position 13 , 14 .

[0169] To move the pressing elements 19, 21, the first and second shells 8, 9 each include a pressing point 8.3, 9.3, preferably on opposite sides of the blade ends (in order to exploit a lever effect and minimize the forces to be applied). The pressing point is configured to receive an external force, as will be described in more detail later. The pressing point 8.3, 9.3 is fixed to a flexible region 8.4, 9.4 that is deformable (made of an elastomer, etc.). The flexible region 8.4, 9.4 is itself fixed to the remaining portion of the first or second shell 8, 9, which is made of a more rigid plastic.

[0170] The pressure points 8.3, 9.3 are realized from a rigid material, typically plastic.

[0171] Alternatively (not shown), the first and second shells 8 , 9 have two holes, preferably opposite the ends of the blades, so as to allow free access to the pressing elements 19 , 21 .

[0172] The user can grasp the receiving device 5 with his 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 of the first and second capsules 3, 4 to be guided towards the output opening 3.6.

[0173] In another embodiment not shown, the receiving device 5 is integrated with the mixer 6 , and the blades can be directly integrated into the mixer 6 .

[0174] Keep stop

[0175] In order to prevent the receiving device 5 from being removed from the receiving portion 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 provide a support point for the holding mechanism 50 on the receiving device 5, a holding stop 9.6 is provided on one of the first or second shells 8, 9 (in the Figure 2A , 2B, 3A, 3B, 4B, 5 are on the second shell 9). The retaining stop 9.6 corresponds primarily to a radially extending protrusion, i.e., a protrusion extending in a plane perpendicular to the longitudinal direction X. The retaining stop 9.6 can be located anywhere along the height of the receiving device 5. In the illustrated embodiment, the retaining stop 9.6 is provided near the insertion surface.

[0176] For example, for ergonomic reasons, a further stop can be provided on the other shell.

[0177] Grip handle

[0178] To allow the user to grip the storage device 5 when it is inserted into the receptacle 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 on the removal surface, which is the surface that is accessible when the storage device 5 is placed.

[0179] The gripping handles 8.7, 9.7 can simply consist of radially extending projections, ie projections extending in a plane perpendicular to the longitudinal direction X, and are long enough to allow a part of the user's knuckle to lift over them.

[0180] Connect Button

[0181] As indicated above, the actuation surfaces 8.1, 9.1 and more particularly the first and second protective shells 8, 9 each comprise a pressure point 8.3, 9.4 in order to transmit a force towards the inner pressure element 19, 21. These pressure points 8.3, 9.4 are formed in the flexible areas 8.4, 9.4.

[0182] When the receiving device 5 is moved to the closed position, the connectors 3, 4, 4, 4 are positioned relative to each other and partially nested. To establish a sealed and reliable fluid connection between the first and second capsules 3, 4, a connecting mechanism 52 is provided in the manufacturing apparatus 2. This connecting mechanism 52 applies a force toward the receiving device 5. This connecting mechanism 52 simultaneously allows the fluid connection between the first and second capsules 3, 4 to be established under the force exerted by the connecting mechanism 52, while also preventing any undesirable disconnection of the first and second capsules 3, 4 due to pressure generated by agitation of the first and second capsules 3, 4. This will be described later.

[0183] One (or even both) of the first or second protective shells 8, 9 comprises a connection button 9.8 which moves towards the second storage position 14 ( Figure 2A , 2B, 3A, 3B, 4A, 4B, 5). More specifically, the connection button is oriented toward the area near the opening 9.2, because the connection button 9.8 is used to press the second capsule 4 near the connection portion 4.2. To this end, the connection button 9.8 is fixed to a flexible area, which can be the flexible area 9.4 of the pressing point 9.3. It should be noted here that the connection button 9.8 is different from the pressing point 9.3.

[0184] The connection button 9.8 is preferably rigid in order to better transmit the force of the connection mechanism 52 to the first and second capsules 3, 4, so that the first and second capsules are kept connected.

[0185] Mixer

[0186] More specifically, if Figure 6 , 7A, 7B, 8A, 8B, 8C, 9, 10A, 11A, 11B, 11C, the mixer 6 includes a support portion 31 and a receiving portion 32, the receiving portion is at least partially defined by the support portion 31 and is configured to at least partially receive the receiving device 5. Figure 1A , in the embodiment shown in FIG1B , the mixer 6 and the receiving device 5 are configured so that when the receiving device 5 is received in the housing 32, the receiving device 5 extends at least partially outside the mixer 6. The support 31 serves as a base, i.e., when the mixer 6 is placed on a support (a table, a work surface . . . ), the support defines the entirety of the fixing element, whether the mixer is in use or not. The support 31 of the mixer 6 further comprises a housing 33 and an insertion opening 34 leading into the housing 32, the receiving device 5 being configured to be inserted into the housing 32 through the insertion opening 34. Advantageously, the insertion opening 34 is arranged in a central portion of the upper surface of the base 33 and is configured to be oriented upwards when the mixer 6 is placed on a horizontal support surface (a table, a work surface . . . ).

[0187] The base 33 also serves as an outer shell, which has a desired design for the mixer. The base 33 may include a lower base and an upper base.

[0188] Actuation system

[0189] 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 placed on a horizontal support surface (table, work surface . . . ). Figure 6 , 8A, 8B, 8C, 9, 10A).

[0190] Preferably, the actuating system 35 performs a reciprocating motion about the pivot axis 36 along a maximum angular travel of 45°. The motion thus consists of a maximum rotation of +45°, then -45°, and so on. The actuating system moves along a nominal travel C35 (not shown in the figures), which is combined with the maximum angular travel when rotating about the pivot axis 36. The nominal travel C35 of the actuating system 35 is defined as the travel between the two extreme positions of the actuating system 35. An intermediate position of the actuating system 35 is defined between these two extreme positions, corresponding to an inserted position in which the receiving device 5 can be positioned inside the housing 32 of the mixer 6 without being disturbed by the actuating system 35.

[0191] The mixer 6 further comprises a drive motor 39 mounted on the support 31. The drive motor 39 is configured to pivot the actuation system 35 about the pivot axis 36 and within a predetermined angular range. Preferably, the drive motor 39 rotates in only one direction.

[0192] The actuation system 35 includes a first actuation member 37 and a second actuation member 38, wherein the first actuation member may include a first actuation finger 37.1, which is configured to transmit pressure to the first capsule 3, and the second actuation member may include a second actuation finger 38.1, which is opposite to the first actuation member 37 and is configured to transmit pressure to the second capsule 4.

[0193] When the receiving device 5 is received in the mixer 6 and more precisely in the housing 32 , the first and second actuating members 37 , 38 are configured to be arranged on both sides of the housing 32 and thus on both sides of the receiving device 5 .

[0194] The actuating members 37, 38 have at least one position in which they are at least partially inside the housing 32. In an intermediate position of the actuating system 35, the actuating members 37, 38 are arranged relative to the housing 32 so as to allow the receiving device 5 to be positioned inside the housing 32 of the mixer 6; this is the insertion position.

[0195] The first and second actuating members 37, 38 are more specifically configured to exert pressure on the first and second pressing elements 19, 21, respectively and alternately, so as to transmit pressure to the first and second compartments 3.1, 4.1, respectively and alternately. In particular, the first and second actuating members 37, 38 are configured to cooperate with the first and second pressing points 8.3, 9.3 of the first and second protective shells 8, 9, respectively, or directly with the pressing elements 19, 21.

[0196] An actuation stroke C37 for the first actuation member 37 and an actuation stroke C38 for the second actuation member 38 are defined.

[0197] The actuation stroke C37 is defined as the stroke of the first actuation member 37 between the middle position of the actuation system 35 and a maximum actuation position of the first actuation member 37 , in which the first actuation member 37 maximally presses the first pressing element 19 .

[0198] Conversely, the actuation stroke C38 is defined as the stroke of the second actuating member 38 between the middle position of the actuation system 35 and the maximum actuation position of the second actuating member 38 , in which the second actuating member 38 maximally presses the second pressing element 21 .

[0199] Preferably, the movement of the actuation system 35 can be tracked by means of various sensors, in particular Hall effect sensors. More precisely, each of the first actuation member 37 and the second actuation member 38 can comprise a magnet for interacting with a fixed Hall effect sensor. Advantageously, the Hall effect sensor can be arranged directly on the control unit 45 to be described later, such as Figure 12 As can be seen, the control unit 45 can thus track the movement of the actuation system 35 and, likewise, the movement of each of the first and second actuation members 37 , 38 . It is also conceivable that the control unit 45 can precisely know the position of each of the first and second actuation members within their respective actuation travels C37 , C38 , for example, by providing a plurality of Hall effect sensors.

[0200] According to the embodiment shown in FIGS. 1 to 12 , the first and second actuating members 37 , 38 extend substantially in the same plane of extension and converge opposite the pivot axis 36 .

[0201] like Figure 6 8A, 8B, 8C, 9, the actuation system 35 has a generally annular shape defining an opening around the housing 32. In an embodiment, the actuation system 35 is primarily formed from a single part that includes an opening for receiving a shaft defining the pivot axis 36.

[0202] The first and second actuating members 37, 38 are each arranged on opposite sides of the actuating system 35. Thus, there is an actuating system 35 extending on two faces facing each other twice: the actuating members 37, 38, the opening for the pivot shaft 36 and the drive mechanism with the groove to be described later.

[0203] The actuating members 37, 38 can each comprise a drive support 37.3, 38.3 which is joined on one side at the pivot axis 36. On the other side, a connecting portion 36.1 is defined which connects the two drive supports 37.3, 38.3. The connecting portion 36.1 can be fixed to the drive supports 37.3, 38.3 or be made of the same material.

[0204] Preferably, the two actuating members 37, 38 rotate about the same pivot axis 36. In this case, the two drive supports 37.3, 38.3 are preferably rotated in one piece.

[0205] However, a pivot axis may be provided for each actuating member 37 , 38 ; however some simple adaptation should be provided.

[0206] Alternatively, in an embodiment not shown, the actuating member is movable in translation.

[0207] spring

[0208] The actuating system 35 moves along a nominal stroke C35 in order to exert a force on the receiving device 5 .

[0209] However, play in the transmission chain, which is related to manufacturing tolerances, can disrupt the transmission of force by varying the position of the actuator system 35. Thus, at the end of the stroke, a few microns may be missing or, conversely, a few microns may be added. This can lead to insufficient compression of the manufacturing device 2 or, conversely, damage to the manufacturing device 2.

[0210] To overcome this problem, the actuation system 35 may include springs 37.4, 38.4 (particularly visible in Figures 8A, 8B, 8C). Specifically, the springs 37.4, 38.4 are configured to compress when the actuation system 35 reaches near the end of its rated travel C35 and the actuation fingers 37.1, 38.1 abut against the flat surfaces 3.7, 4.7 of the capsule. The springs 37.4, 38.4 thus generate a force tending to separate the actuation members 37, 38 of the receiving device 5.

[0211] More precisely, each actuating member 37 , 38 comprises a spring 37 . 4 , 38 . 4 .

[0212] The springs 37.4, 38.4 may be located in different positions. In an embodiment not shown, the springs 37.4, 38.4 are located at the "free" ends of the fingers 37.1, 38.1.

[0213] In another embodiment, the springs 37.4, 38.4 are mounted between the fingers 37.1, 38.1 and the drive supports 37.3, 38.3, preferably because the springs are covered. Thus, the springs are not accessible to the user because they are behind the base.

[0214] In order to place the spring in this position, for each actuating member 37, 38, an arm 37.2, 38.2 is simply provided which is movably mounted relative to the drive support 37.3, 38.3. The fingers 37.1, 38.1 are thus mounted integrally with the arms 37.2, 38.2.

[0215] In particular, Figure 8A In the embodiments shown in Figures 8B, 8C and 9, the arms 37.2 and 38.2 are rotatable relative to the drive supports 37.3 and 38.3 via hinges 37.5 and 38.5. 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.

[0216] The springs 37.4, 38.4 therefore work in compression, meaning that the idle or unstressed position of the springs is not compressed. The springs are compressed in the translational or rotational direction of the actuating members 37, 38.

[0217] The springs 37.4, 38.4 can be of the spiral, leaf type or even comprise elastic material or elastic assembly (elastomer, bubble, etc.).

[0218] Rotary drive

[0219] according to Figure 6 8A, 8B, 8C, and 9, the mixer 6 further includes a cam 41 in the form of a drive wheel or arm, which is rotationally connected to the output shaft 39.1 of the drive motor 39 and is configured to be rotationally driven about the cam's rotation axis 41.1. The cam 41 is mounted on the support portion 31. To allow for reciprocating motion with a large lever arm, the pivot shaft 36 and the cam 41 are preferably located on both sides of the receiving portion 32.

[0220] The cam 41 is equipped with a drive finger 42 which is eccentric with respect to the axis of rotation 41 . 1 of the cam.

[0221] The cam 41 is typically driven by the drive motor 39 via 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 drive chain is as follows: belt 39.2, pulley 39.3 connected to pulley 39.4 via a shaft, belt 39.5, cam 41.

[0222] The drive finger 42 is received in a drive recess 43 provided on the actuation system 35. Specifically, the drive recess 43 is formed in the connecting portion 36.1. The drive recess 43 is elongated and extends in a direction generally parallel to the extension of the pivot axis 36. This configuration of the mixer 6 allows the actuation system 35 to be reciprocated while the drive motor 39 always rotates in the same direction of rotation, eliminating the need for an expensive control system for the drive motor 39.

[0223] The driving groove 43 extends along its depth toward the pivot axis 36 .

[0224] The connection between the drive groove 43 and the drive finger 42 will now be described. The alignment of the drive groove 43 and the drive finger 42 is variable as the actuation system 35 rotates, meaning that a simple adjustment can cause the system to become jammed. Conversely, the presence of a gap that causes misalignment can produce noise and add a delay to the end of each stroke.

[0225] In order to solve this problem, a ball-and-socket connection is provided between the drive finger 42 and the drive groove 43 , which allows the aforementioned misalignment to occur.

[0226] Specifically, a ball 42.1 is mounted on the drive finger 42 and accommodated in a ring 43.1. The connection between the ball 42.1 and the ring 43.1 is a ball-and-socket joint. The ring 43.1 itself is housed in the drive groove 43, where it is mounted for translational movement parallel to the pivot axis 36 (and therefore along the length of the drive groove 43). Finally, the ball 42.1 is mounted for translational movement along the drive finger 42. The arrangement of these various connections can be varied, meaning that the ring can also be translationally movable along the depth of the groove, while the ball is thus fixed to the drive finger.

[0227] Thus, the complete connection between the drive finger 42 and the actuation system 35 comprises, in sequence, a guide rail, a ball joint, and a guide rail perpendicular to another guide rail. Thus, in the kinematic torque, it is noted that the force is transmitted only on one of the six torque components, namely the component that translates tangentially to the rotational motion of the actuation system 35, i.e., the component that allows the rotation of the actuation system 35. The kinematic equivalent is a spherical joint (also called a point joint).

[0228] In order that the connection is not unnecessarily complicated, the axis of rotation 41 . 1 of the cam and the pivot axis 36 are preferably orthogonal. This allows for a drive finger 42 that performs a circular movement in a plane parallel to the pivot axis 36 .

[0229] The movement of some arrangements of the connection can be easily achieved by means of plastic slides / plastic, which wear slowly enough to ensure a satisfactory lifespan.

[0230] According to an embodiment of the present invention, the mixer 6 can be configured so that the rotation of the drive motor 39 in a first rotational direction drives the actuating part 35 to pivot in a first pivoting direction, and the rotation of the drive motor 39 in a second rotational direction opposite to the first rotational direction drives the actuating part 35 to pivot in a second pivoting direction opposite to the first pivoting direction.

[0231] Eccentricity of the pivot axis

[0232] The actuating members 37 , 38 each move along an actuating stroke C37 , C38 .

[0233] However, in the embodiment shown in the figures, one of the two actuating members 37, 38 has an actuation stroke C37, C38 whose length is strictly greater than that of the other actuating member. This difference in actuation strokes C37, C38 allows for better mechanical and electrical management of the forces to be applied in order to deform the first capsule 3 relative to the second capsule 4. In fact, as Figure 2BAs shown, the first capsule 3 has a greater thickness than the second capsule 4 , which means that more space is needed on the side of the thickest capsule and the pressing element 19 will come into contact faster and work faster than the pressing element 21 .

[0234] In order to achieve this difference in stroke, several solutions are conceivable. One solution consists in having a drive groove 43 which is not centered in the connecting part 36.1.

[0235] especially Figure 8A Another solution, shown in Figures 8B, 8C, and 9, is to offset the pivot axis 36. On the other hand, the cam's rotation axis 41.1 does not intersect the pivot axis 36. This results in a difference in the travel of the two actuating members 37 and 38 when the cam 41 completes a full revolution. A distance between the cam's rotation axis 41.1 and the pivot axis 36 (orthogonally, 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 significantly affect the overall symmetrical appearance. In absolute terms, a distance between 1 mm and 2 mm is suitable.

[0236] The eccentricity can also be defined by means of the axis of rotation of the housing 32 relative to the cam 41 : the end positions of the actuating system 35 are therefore not centered around the housing 32 .

[0237] The eccentricity can also be defined relative to the first and second seating surfaces 11.1, 12.1 or relative to the position of the first and second capsules 3, 4 in the housing 32: by means of the flat surfaces 3.7, 4.7, which thus define an imaginary surface in the housing 32. The maximum distance of the first actuating member 37 from the surface of the flat surface 3.7 is greater than the maximum distance of the second actuating member 38 from the flat surface 4.7.

[0238] To this end, in a variant, the pivot axis 36 is contained in a plane equidistant from the two rest surfaces 11 . 1 , 12 . 1 .

[0239] Due to 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 eccentricity compensates for the extreme positions of the actuating fingers 37.1, 38.1. More precisely, the actuating finger 37.1, 38.1 operating on the thicker first or second capsule 3, 4 has a greater length than the other actuating finger 37.1, 38.1.

[0240] Figure 8AAnother solution shown aims to delimit the intermediate position of the actuation system 35 when the cam 41 is at its upper or lower dead center. In fact, the distribution of the actuation strokes C37, C38 is staggered by selecting the intermediate position of the actuation system 35 at a non-zero angle Ag (typically Ag between 5° and 30°) relative to the 12 o'clock position (when the mixer 6 is placed on a horizontal support). Furthermore, it should be noted that another intermediate position is thus obtained for an angle Ag' corresponding to Ag'=180°-Ag.

[0241] In fact, the actuation strokes C37 and C38 at the cam 41 correspond to a rotation from the angle Ag to the nearest 90° (i.e., at 3 o'clock or 9 o'clock, when the mixer 6 is placed on a horizontal support), and then to a rotation from the angle Ag' to 270°. Since Ag and Ag' are not at 0° and 180° (12 o'clock and 6 o'clock), it is immediately noticeable that the strokes C37 and C38 are not equal. For a complete rotation of the cam 41, the first actuation stroke C37 is traversed in the first direction, then the first actuation stroke C37 is traversed in the second direction, then the second actuation stroke C38 is traversed in the first direction, and then the second actuation stroke C38 is traversed in the second direction, i.e., twice the nominal stroke C35.

[0242] Contact rails for mixers

[0243] As mentioned above, the mixer 6 itself also comprises electrical contact tracks 31.11, 31.12 configured to engage with the electrical contact tracks 23.1, 24.1 of the longitudinal grooves 23.2, 24.2 of the receiving device 5 and electrical contact tracks 31.51, 31.52 configured to engage with the complementary electrical contact tracks 46.51, 46.52 of the longitudinal grooves 23.2, 24.2.

[0244] These electrical contact rails are mounted on the guide rails 31.1, 31.2 ( Figure 1A , 7A), the guide rails 31.1, 31.2 are integral with the support portion 31 and mounted on both connecting sides of the receiving portion 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 complements the position of the electrical contact rails 23.1, 24.1 (and 46.5, 46.52) on the connecting surfaces 23, 24 of the receiving device 5. The guide rails 31.1, 31.2 help define the receiving portion 32. The guide rails are, for example, located at the edge and preferably fixed to the support portion 31 along their entire length.

[0245] The location of the electrical contact tracks 31.51, 46.51 and 31.52, 46.52 on two opposite and spaced-apart guide rails 31.1, 31.2 has the advantage of limiting the risk of short circuits if liquid flows by gravity onto one of the guide rails 31.1, 31.2.

[0246] Blocking mechanism, connecting mechanism, removal mechanism

[0247] The mixer 6 further includes a holding mechanism 50, a connecting mechanism 52 and a clamping mechanism 54 ( Figure 10A , 10B, 10C, 10D, 10E, 10F, 11A, 11B, 11C).

[0248] Each of these mechanisms has its own and independent function. However, these mechanisms can advantageously be driven simultaneously by the same auxiliary motor 40.

[0249] The function of the holding mechanism 50 is to prevent the storage device 5 from being taken out during stirring.

[0250] The retaining mechanism 50 is movably mounted between an insertion position and a retaining position relative to the support portion 31. In the insertion position, the retaining mechanism 50 allows the insertion and removal of the container 5 relative to the mixer 6. In the retaining position, the retaining mechanism 50 prevents the removal of the container 5 (and thus the insertion of the container).

[0251] The retaining mechanism 50 comprises a movable element 50.1 movable between the two aforementioned positions, which extends in the housing 32 in the retaining position. Specifically, in the retaining position, the movable element 50.1 cooperates with the retaining stop 9.6 to prevent translational movement of the receiving device 5 intended for removal from the mixer 6 (in fact, in the event of removal, the retaining stop 9.6 snaps against the movable element 50.1). To this end, when the receiving device 5 is placed in the mixer, the movable element 50.1 and the retaining stop 9.6 are arranged to be located near the retaining position, preferably less than 2 mm.

[0252] exist Figure 10A In the embodiment shown in Figures 10B and 10C, the movable element 50.1 is a wheel, i.e., a retaining wheel, which is movable about a wheel rotation axis 50.2. The wheel 50.1 has at least two different radii, a smaller radius configured not to extend into the receptacle 32 in the insertion position, and a larger radius configured to extend into the receptacle 32 in the retaining position so as to contact against the retaining stop 9.6 in the case of removal.

[0253] The wheel 50.1 is preferably circular with a flat portion that allows for insertion into position.

[0254] The wheel 50.1 is mounted on a shaft extending along the wheel rotation axis 50.2. The shaft comprises a gear 51 or pulley connected to at least one further gear or further pulley 51.1.

[0255] Alternatively, the movable element 50 . 1 is movable in translation, for example by means of a rack and pinion system via a gear wheel 51 .

[0256] The function of the connection mechanism 52 is to establish a sealed connection between the first and second capsules 3 , 4 by pressing on the connection button 9 . 8 of the second protective shell 9 and to ensure that the first and second capsules remain well nested via their connection joints 3 . 4 , 4 .

[0257] The connection mechanism 52 is movably mounted relative to the support portion 31 between an insertion position and a connection position. In the insertion position, the connection mechanism 52 allows insertion and removal of the receiving device 5. In the connection position, the connection mechanism 52 locks the first and second capsules 3,4.

[0258] The connecting mechanism 52 includes a connecting element 52.1 that is movable between the two aforementioned positions. In the connected position, the connecting element 52.1 extends within the receptacle 32. Specifically, in the connected position, the connecting element 52.1 cooperates with a connecting button 9.8 that moves within the second storage location 14. Therefore, when the storage device 5 is installed in the mixer 6, the connecting element 52.1 and the connecting button 9.8 are opposite each other.

[0259] exist Figure 10A In the embodiment shown in Figures 10B and 10C, the connecting element 52.1 is a wheel, i.e., a connecting wheel, which moves about a wheel rotation axis 52.2, which preferably coincides with the wheel rotation axis 50.2. The wheel 52.1 has at least two different radii, a smaller radius configured not to extend into the receiving portion 32 in the inserted position, and a larger radius configured to extend into the receiving portion 32 in the connected position so as to contact and press the connecting button 9.8.

[0260] The wheel 52 . 1 preferably has an oval shape in the plane.

[0261] Wheel 52.1 is mounted on a shaft extending along wheel axis of rotation 52.2. The shaft comprises a gear or pulley connected to at least one further gear or pulley 51.1. The shaft and gear are preferably identical to shaft and gear 51. This results in a first rotationally connected sub-integral.

[0262] Alternatively, the connecting element 52 . 1 is movable in translation by means of the gear wheel 51 , for example via a rack and pinion system.

[0263] The connection mechanism 52 is different from the actuation system 35. This is caused by the different position (eg different height) in the mixer 6. Similarly, the receiving device 5 comprises different pressing points 8.3, 9.3 than the connection button 9.8.

[0264] The function of the clamping mechanism 54 is to clamp the outlet channel 3.5 of the first capsule 3 while the mixing process is in progress. In fact, the pressure inside the first or second capsule 3, 4 can cause an undesired discharge of the cream. In this case, the cream spreads in the mixer 6, which is to be avoided. This is Figure 11A , shown in 11B, 11C.

[0265] The clamping mechanism 54 is movable relative to the support portion 31 between an insertion position and a clamping position. In the insertion position, the clamping mechanism 54 allows insertion and removal of the receiving device 5 carrying the first capsule 3. In the clamping position, the clamping mechanism 54 clamps the output channel 3.5.

[0266] The clamping mechanism 54 comprises a clamping wheel 54 . 1 which is rotatable about a clamping wheel axis 54 . 2 .

[0267] The mixer 6 also includes a fixed guide wall 54.3 (integrally connected to the support 31, or even made of the same material as the support), and a clamping wall against which the clamping wheel 54.1 rolls or slides, and against which the clamping wheel is clamped in the clamping position. The clamping wall is advantageously part of the guide wall 54.3. Several variants are distinguished: a variant in which the clamping wheel 54.1 approaches the guide wall 54.3 towards the clamping position, a variant in which the distance is constant or variable, and a clamping wall having a special recess for catching the clamping wheel 54.1 (this is possible due to the translationally movable clamping wheel 54.1, as will be seen below).

[0268] The teeth 54.11 present on the clamping wheel 54.1 (in practice, the wheel comprises a circular or substantially circular portion and a toothed portion, the circular or substantially circular portion gripping the first capsule 3, the toothed portion preferably being located below the circular portion) can engage in the teeth 54.31 in the guide wall 54.3, causing the clamping wheel 54.1 to roll against the guide wall 54.3. Furthermore, thanks to the teeth 54.11, 54.31, the clamping wheel 54.1 has a rolling motion against the clamping wall 54.3 without a sliding motion, which avoids the risk of slippage that would result in a poor grip on the delivery channel 3.5. Finally, thanks to the teeth 54.11, 54.31, the distance between the clamping wheel 54.1 and the guide wall 54.3 (excluding the teeth, i.e., the average distance) can be reduced to almost zero below the first capsule 3, while maintaining the rolling motion against the guide wall 54.3.

[0269] In order to allow this transmission, the clamping wheel 54.1 is mounted, preferably rotationally movable, on an arm 54.5, which itself is rotationally movable about an arm axis of rotation 54.51.

[0270] The arm 54.5 is integral with a gear (or pulley) or gear portion 54.52, which itself is connected to the common gear 40.1 via various gears or pulleys. Thus, the arm 54.5 is rotationally driven by the same auxiliary motor 40.

[0271] To ensure clamping in the clamped position, including when the auxiliary motor 40 is no longer energized, the clamping wheel 54.1 is mounted so as to be movable in radial translation along the arm 54.5. A restoring mechanism 54.4, disposed between the clamping wheel 54.1 and the arm 54.5, tends to separate the clamping wheel 54.1 from the arm's axis of rotation 54.51 and, therefore, tends to force the clamping wheel 54.1 against the guide wall 54.3. More precisely, an intermediate support is provided, encompassing the axis of rotation 54.2 of the clamping wheel 54.1. This support is movable in translation relative to the shaft 54.5. In the intermediate support, a sliding connection with a pin 54.42, which slides in a groove 54.53 in the shaft 54.5, allows for guided translation and, advantageously, also for limiting translational movement.

[0272] The restoring mechanism 54.4 thus works in compression, wherein, by default, the restoring mechanism is not compressed (or very little compressed). A coil spring, a leaf spring or other types of springs may be suitable.

[0273] Due to the restoring mechanism 54.4, the clamping wheel 54.1 can remain against the guide wall 54.3 even if the distance between the guide wall 54.3 and the arm rotation axis 54.51 is variable (the distance may gradually decrease towards the area where the outlet channel 3.5 is located).

[0274] Shared drive

[0275] Preferably, the holding mechanism 50, the connecting mechanism 52 and the clamping mechanism 54 are driven simultaneously by a common drive, as described according to the following embodiments. The holding mechanism 50 is driven by a gear 51 connected to at least another gear 51.1 ( Figure 10A , 10B).

[0276] The connecting mechanism 52 is driven by a gear connected to at least one other gear, preferably the gear 51 and another gear 51.1 ( Figure 10A , 10B).

[0277] The clamping mechanism 54 is driven by the gear parts 54 , 52 .

[0278] Different drive chains may be provided, but preferably a common gear 40.1 is provided which then drives the further gear 51.1 and the gear section 54.52.

[0279] like Figure 11A , 11B, 11C, a common gear 40.1 is located on the output shaft of the auxiliary motor 40. This common gear meshes directly with a gear 51.1, which is mounted on a shaft containing another gear 51.2. This gear 51.2 itself meshes with gear sections 54.52. This results in a very simple transmission chain with a minimum number of gears, and therefore minimal friction losses, minimal risk of damage, and very little backlash.

[0280] Due to this common gear 40.1 located on the output shaft of the auxiliary motor 40, at least two of the three mechanisms 50, 52, 54 are simultaneously in the insertion position, the holding position, the connection position or the clamping position. The same auxiliary motor 40 thus drives the three mechanisms, which constitutes a major simplification of the mixer 6 and its operating principle.

[0281] Visual and sound display

[0282] The mixer 6 advantageously comprises a screen 60 and / or a speaker ( FIGS. 1A , 1B , 7 ) allowing the exchange of information with the user.

[0283] The screen 60 is preferably touch-sensitive so as to avoid physical buttons. The screen allows the user to indicate the start of a cycle and the moment of removal. The screen 60 can also display the end of a cycle, for example accompanied by a sound reminder.

[0284] Power supply and control unit

[0285] According to an embodiment of the present invention, the mixer 6 further comprises a power supply (not shown in the figure), which is configured to power the mixer 6, in particular the drive motor 39 and the auxiliary motor 40. The power supply advantageously or even exclusively comprises at least one rechargeable battery 44 ( Figure 7B ). In the example shown, the rechargeable battery 44 is advantageously formed by a lithium-ion battery having two cells, which provides a nominal output voltage of 7.4V.

[0286] like Figure 12As shown, the mixer 6 also includes a control unit 45, which includes, for example, a controller such as a microcontroller or processor 45.1, configured to control the operation of the production device 2, more specifically the operation of the drive motor 39, the auxiliary motor 40, the heating element 46, the temperature sensor, and the screen 60 (preferably a processor in the case of the screen), as well as any audio or visual devices. The control unit 45 advantageously includes a non-volatile memory 45.2 that stores instruction lines in the form of a program to be executed by the control unit or processor 45.1, in particular to implement some of the steps described in the following method.

[0287] Other Implementations

[0288] In a variant, the holding device 5 is integrated with the mixer 6. It is therefore only necessary to insert the first or second capsule 3, 4 into the first or second receiving location 13, 14. A housing 32 is still defined, which corresponds to the space occupied by the receiving device 5.

[0289] Furthermore, in this variant, the actuation surfaces 8 . 1 , 9 . 1 may not be present: the actuation members 37 , 38 in this case press directly on the first or second capsule 3 , 4 .

[0290] How to use

[0291] At least one manufacturing method for manufacturing a composition, such as a cosmetic product, using manufacturing apparatus 2 will now be described. This manufacturing method is broken down into a number of sub-methods (referred to as "methods" for clarity), and one or more variations of this method will be described. Specifically, a preparatory method Ep, an initial method Ei, a mixing method Em, and a removal method Er are described.

[0292] In particular, these methods (or their variants) are advantageously implemented by means of the different embodiments of the above-described manufacturing device 2. Preferably, most of the steps of methods Ei, Em and Er are stored in a non-volatile memory 45.2 in the form of code lines executable by the processor 45.1.

[0293] The preparation method Ep comprises a preparation step Ep1 for preparing the entire use of the manufacturing device 2, which is intended to connect the manufacturing device to the grid or charge the battery 44. Furthermore, this preparation step Ep1 may be preceded or followed by a step Ep2 of placing the manufacturing device 2 on a flat support and, if necessary, by a power-on step.

[0294] The initial method Ei is then implemented. In step Ei1 ("receiving step"), the processor of the manufacturing device 2 receives a start command. This start command is typically generated by a user action (contact with the touch screen 60, a button, a switch, etc.).

[0295] After this step Ei1, in step Ei2 ("verification step"), the method ensures that the actuation system 35 is in an intermediate position that allows the insertion of the receiving device 5 or the first and second capsules 3, 4. Typically, it should be ensured that the 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) is not blocked by the actuation system 35. During this step Ei2, it is also appropriate to check that the clamping mechanism 54, the connecting mechanism 52, and the retaining mechanism 50 are not activated, i.e., are in their respective insertion positions.

[0296] After this step Ei2 , the receiving device 5 comprising the first or second capsule 3 , 4 can be inserted manually into the housing 32 , or even directly.

[0297] Finally, in the subsequent step Ei3 (closing step), at least one of the clamping mechanism 54, the connecting mechanism 52, and the retaining mechanism 50 is activated, i.e., they move. This step Ei3, for example, involves the processor issuing a command to the auxiliary motor 40 to activate the auxiliary motor, causing it to drive all three mechanisms, while they are all connected to a common gear (or pulley) 40.1. The auxiliary motor 40 moves from a first position to a second position, causing the clamping mechanism 52, the connecting mechanism 54, and the retaining mechanism 50 to move from their respective insertion positions to their respective clamping, connecting, and retaining positions. Preferably, the auxiliary motor 40 maintains the second position at the end of step Ei3, even if the auxiliary motor is no longer powered.

[0298] Steps Ei1 , Ei2 , Ei3 are executed in particular by the processor 45 . 1 .

[0299] After this initial process Ei, the mixer 6 is ready to start working on the first and second capsules 3 , 4 : this is the purpose of the mixing process Em and the removal process Er.

[0300] The mixing method Em comprises a first step Em1 ("initial step of setting the actuation system in motion") during which the connecting solder of the capsule located further from the heating element 46 (in the figure, the second capsule 4) is broken up and the capsule is compressed so that its contents are partially directed toward the capsules closer to the heating element 46. According to the embodiment shown, the second actuation member 38 is moved to break up the connecting solder in the second capsule 4 (which, for example, contains an oil-phase formulation). As a result, a portion of the contents of the second capsule 4 is directed toward one side of the first capsule 3, in particular into the connecting channel 3.3 (because the connecting solder of the first capsule 3 has not yet been broken up). The second actuation member 38 preferably moves along its actuation stroke C38. For reasons of design simplicity, a partial stroke sensor for the second actuation member 38 is not required.

[0301] During step Em2 of the preparation phase ("second step of moving the actuation system" or "prestressing step"), the first actuating member 37 is moved along a partial stroke, strictly less than its actuation stroke C37, and maintained in position, in order to exert a prestress on the first capsule 3 (which, for example, contains the aqueous formulation) so that the flat surface 3.7 is pressed against the diffuser plate 46.2. This prestressing facilitates heat exchange between the diffuser plate 46.2 and the first capsule 3 during the subsequent step Em3 ("heating step"). It should be noted that, due to the partial movement of the first actuating member 37, this pressing of the first capsule 3 against the diffuser plate 46.2 is performed without causing a break in the connecting solder in the first capsule 3 (which would cause the formulation of the first capsule 3 to be released toward the second capsule 4).

[0302] In step Em3 ("heating step") of the preparation phase, the heating element 46 is activated to generate heat toward the first capsule 3. Since the heating element 46 is positioned on the side of the flat surface 3.7 of the first capsule 3 and the prestressing step has already allowed good thermal contact between the diffuser plate 46.2 and the first capsule 3, the heat provided by the heating element 46 is well distributed over the contents of the first capsule 3. Step Em3 is therefore activated without any significant movement of the actuating members 37, 38.

[0303] During step Em3 of the preparation phase, the temperature of the heating element 46 reaches a target temperature Tc between 80° C. and 90° C. The purpose of this target temperature Tc is to bring the contents of the first capsule 3 to a target temperature Tc′ also between 80° C. and 90° C., preferably approximately 85° C. In fact, it is observed that the temperature of the contents of the first capsule 3 during this heating step Em3 corresponds approximately to the target temperature Tc of the heating element 46, albeit with a slight time difference.

[0304] Then, in step Em3 ' ("mixing step") of the stirring phase, the heating element 46 is deactivated, and the first actuating member 37 is then moved along its rated stroke in order to break up the connecting solder in the first capsule 3. The interruption of the power supply to the heating element 46 before the activation of the first actuating member 37 allows the integrity of the power provided by the power supply source, which can be used to power the drive motor 39. This feature is particularly advantageous in the case where the mixer 6 is powered by a low-power power converter or battery 44. In fact, this feature avoids the situation where the power supplied to the drive motor 39 is insufficient to allow the connecting solder of the first capsule 3 to break (which would cause the device to jam), and this breaking step of the connecting solder requires a large motor torque. When the first actuation member 37 reaches the end of its actuation stroke C37, the content of the first capsule 3 is sent into the second capsule 4 and both formulations can thus circulate freely during each reciprocating movement of the actuation system 35 from the first or second capsule 3,4 towards the second or first capsule 4,3 via the connecting portion 3.2,4.2, the connecting solder originally present in each of the first and second capsules 3,4 having been broken.

[0305] Subsequently, steps Em4, Em5, Em6 are successive steps of stirring, with or without heating (called stirring phases).

[0306] Step Em4 of the stirring phase ("non-heating stirring step") is designed to reciprocate the actuating members 37, 38 without activating the heating element 46, i.e., without heating. During this step, the first and second capsules 3, 4 are each deformed at least once. According to embodiments, step Em4 lasts for at least 1.4 seconds, and preferably between 2 and 4 seconds. This non-heating stirring step allows the drive motor 39 to be operated at a constant speed, while also maximizing the overall power consumption of the power supply.

[0307] Steps Em1, Em2 and Em3, Em3', Em4 alternate between the movement of the actuation system 35 and the heating by the heating element 46. This is achieved by dedicating power to either the actuation system 35 or the heating element 46. This unique alternation allows the battery 44 to be protected by allocating high-power moments. The initiation of movement generates a high resistive torque, which requires a high motor torque, and the temperature rise also requires a high power level: the battery 44 is therefore subject to high demands. This alternating solution also allows for a reduction in the size of the components, which is inherent in the manufacture of the mixer and is a design constraint on the battery.

[0308] Conversely, once the temperature is around the target temperature Tc′ and once the actuation system 35 has arrived, the demand on the battery 44 is reduced and it is permitted to power the heating element 46 and the actuation system 35 in parallel: this is the purpose of step Em5 .

[0309] During step Em5 of the stirring phase ("stirring step with heating"), the actuation system 35 remains activated and the heating element 46 is activated to keep the formulation mixed at a temperature, preferably the target temperature Tc'. The heating element is thus maintained at the target temperature Tc. This step Em5 lasts, for example, between 5 and 30 seconds, and preferably between 7 and 15 seconds. Although the battery 44 is less frequently required than for startup or temperature rise, it may tend to discharge rapidly during this phase, which is of limited duration.

[0310] However, this step Em5 is long enough so that the first and second capsules 3 , 4 are each deformed multiple times and the emulsion obtained by mixing the preparations is satisfactory.

[0311] Between steps Em4 and Em5 , the actuation system 35 is not stopped.

[0312] Subsequently, step Em6 ("cooling step with stirring") is carried out, which is a stirring phase. Alternatively, this step can be carried out without stirring, but preferably the activation system 35 remains activated in order to improve or maintain the homogenization of the preparation. During step Em6, the temperature of the cream decreases to a removal temperature Tr', which is between 35°C and 48°C, and preferably between 38°C and 42°C. In the case of the embodiment shown, the removal temperature Tr' of the cream corresponds to the removal temperature Tr of the heating element 46, which is between 55°C and 60°C. This temperature difference between the contents of the first and second capsules 3, 4 and the temperature of the heating element 46 during the cooling step is explained in particular by the fact that, during stirring, the composition is only present in the first capsule 3 for a portion of the time and is therefore only facing the diffuser plate 46.2 for a portion of the time, where the temperature measurement is performed.

[0313] The simplest cooling technique is to de-energize the heating element 46 and allow the cream to cool by passing air at ambient temperature. Therefore, the duration of step Em6 effectively depends on the ambient temperature. For this purpose, the temperature sensor is advantageously located in the mixer 6 and, more specifically, in the container 5. To limit the number of temperature sensors, a single sensor measures the temperature of the heating element 46.

[0314] As in the embodiment shown, a temperature sensor measures the temperature of the heating element 46 , again the same sensor is used: this means that the end of step Em6 is determined by the temperature measured by said sensor, ie by a take-off temperature Tr′ comprised between 55°C and 60°C.

[0315] Once the removal temperature is reached, the actuation system 35 is deactivated.

[0316] The cooling step Em6 generally lasts at least 20 seconds and preferably 40 seconds.

[0317] In a variant embodiment, step Em6 may also advantageously include a minimum stirring duration of, for example, approximately 40 seconds, which allows for good emulsification to be ensured, followed by a supplementary stirring duration, which is only applied if the removal temperature Tr' has not yet been reached. Alternatively, stirring is continued for a certain duration even when the temperature is below the removal temperature Tr'.

[0318] It should be noted that, according to an embodiment not shown, the mixer 6 can include a cooling system for cooling the cream in an efficient manner and accelerating the process. For example, a cooling system can be provided equipped with a small-sized fan, with or without a cooling element, which forces air to circulate in the mixer 6, thus forcing cooling by strong convection.

[0319] Once the mixing method Em is finished, the removal method Er can be started. This removal method Er will now be described.

[0320] Since the above steps take a certain amount of time (usually more than one minute), the user may not be near the blender 6 but may be busy with his or her daily routine (eating breakfast, listening to the radio, watching TV, buttering bread, getting dressed, ironing clothes, etc.). Therefore, it is important that the blender 6 can keep the cream in a ready-to-use state for a predetermined duration.

[0321] To this end, in step Er1 ("transfer step for storage"), the actuation system 35 is activated once to transfer the cream into the capsule (ie here the first capsule 3) situated on the side of the heating element 45. This step is optional once step Em6 has been stopped in a good configuration.

[0322] In step Er2 ("prestress maintenance step"), the actuator system 35 is reset to the prestressed position, wherein the first actuating member 37 applies prestress to the first capsule 3 to force it against the diffuser plate 46.2. Then, in step Er3 ("maintain temperature step"), the heating element 46 is activated to maintain the cream at the removal temperature Tr'. Step Er2 for maintaining the prestress allows for better heat conduction, as does step Em2. Preferably, agitation or movement of the actuator system 35 is periodically applied during step Er3 to ensure good emulsification, which could be partially impaired by the presence of hot spots on the diffuser plate 46.2.

[0323] In a variant embodiment, the removal method may comprise, instead of step Er2, a step Er2' ("maintenance step in an intermediate position"), in which the actuation system 35 is activated so as to be placed in an intermediate position, i.e. without forcing the first or second capsules 3, 4 and in particular without forcing the first capsule 3 against the heating element 46. Surprisingly, this variant allows better emulsification to be maintained and avoids agitation during the use cycle during the holding phase.

[0324] Step Er3 is performed during a predetermined waiting duration, which is less than 15 minutes so as not to energize the heating element 46 for too long, and greater than 1 minute and preferably about 5 minutes so as to allow the user flexibility in morning time management.

[0325] On the other hand, this means that after the movement of the actuation system 35 has ended, the user has between 1 minute and 15 minutes and preferably about 5 minutes (depending on factory or user parameter selection) to return the cream to a good temperature.

[0326] As soon as the user is ready to use the cream, he touches the touch screen or presses a button, which initiates step Er4 (“step of receiving the removal instruction”), during which the mixer 6 receives the removal command.

[0327] Then, in step Er5 (“step of placing in the intermediate position”), the actuation system 35 is activated so as to be placed in the intermediate position.

[0328] In the case where the actuation system 35 is prestressed at the first actuation member 37, the first actuation member should complete its movement, which has transferred the formulation to the second capsule 4, and then the actuation system 35 stops in an intermediate position, which corresponds 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, from the start of the drive motor 39, the second actuation member 38 is ready to compress the second capsule 4 in step Em1.

[0329] In the case of a variant embodiment, the actuation system 35 is already in an intermediate position at step Er2', and for the insulation at step Er3, it may be necessary for the actuation system 35 to perform a reciprocating movement so as to be positioned in an intermediate position suitable for implementing the next manufacturing cycle of the above-mentioned method, i.e., the second actuation member 38 is ready to compress the second capsule 4 at step Em1.

[0330] Upon this reciprocating movement of the actuation system 35 , the cream present in the first capsule 3 is partially sent into the second capsule.

[0331] Finally, in a final step Er6 (unlocking step), each mechanism activated in step Ei3 is placed in the insertion position. Likewise, this step Er6 means activation of the auxiliary motor 40.

[0332] The user then grasps the container 5 and removes it from its housing 32. The user then presses the actuation surfaces 8.1, 9.1 to pivot the blades, thereby expelling the cream present in the first and second capsules 3, 4 through the outlet channel 3.5 of the first capsule 3. Finally, the user removes the first or second capsule 3, 4 from the container 5, making it ready for use again. In fact, no part of the mixer 6 (the production device 2 or the container) comes into contact with the formulation.

[0333] The different steps of carrying out the above-described method can, for example, be carried out in succession, thus being the following steps:

[0334] Ei1: a receiving step (implemented by the mixer and more precisely by the processor) of receiving a start command;

[0335] Ei2: Positioning step of the actuation system (implemented by the mixer and more precisely by the processor controlling the drive motor);

[0340] Em3′: mixing step by the movement of the actuation system (implemented by the mixer and more precisely by the processor controlling the drive motor) for breaking the connecting solder of the other capsule and allowing free circulation of the formulation between the capsules;

[0341] Em4: stirring step without heating for starting the motor at a constant speed (implemented by the mixer and more precisely by the processor controlling the drive motor);

[0342] Em5: stirring step with heating for achieving emulsification (implemented by the mixer and more precisely by the processor controlling the drive motor and the heating element);

[0343] Em6: cooling step with stirring and without heating (cooling) to the take-out temperature (implemented by a mixer whose processor controls the drive motor);

[0344] Er1: optional step for transfer of storage by movement of the actuation system (implemented by the mixer and more precisely by the processor controlling the drive motor);

[0345] Er2: a step of placing the actuation system in a prestressed position (implemented by the mixer and more precisely by the processor);

[0346] Er2′: a step of placing the actuation system in an intermediate position (which may replace step Er2) (implemented by the mixer and more precisely by the processor controlling the drive motor);

[0347] Er3: holding step (implemented by a mixer and more precisely by a processor);

[0348] Er4: a receiving step of receiving a fetch command (implemented by the mixer and more precisely by the processor);
