Description

MANUFACTURING APPARATUS, MIXING MACHINE AND / OR RECEIVING DEVICE FOR MANUFACTURING A COMPOSITION FROM

A MIXTURE OF FORMULATIONS

GENERAL TECHNICAL AREA

The present invention relates to a manufacturing apparatus for the manufacture of a composition, in particular a cosmetic composition, or more precisely for the preparation of a composition by mixing two formulations.

STATE OF THE ART

Document FR3026622 discloses a manufacturing device for the manufacture of a composition, and more particularly of a cosmetic product, the manufacturing device comprising:

- a first capsule comprising a first compartment containing a predetermined quantity of a first formulation, and a first connection part,

- a second capsule comprising a second compartment containing a predetermined quantity of a second formulation, and a second connection part configured to be connected to the first connection part, and

- a mixing machine configured to receive the first and second capsules, and to mix the first and second formulations directly inside the first and second capsules so as to obtain the cosmetic product.

The mixing machine notably includes:

a first support element comprising a first support surface configured to exert, on the first deformable compartment of the first capsule, a pressure force which is orthogonal to the direction of movement of the first support element,

a second support element comprising a second support surface configured to exert, on the second deformable compartment of the second capsule, a pressure force which is orthogonal to the direction of movement of the second support element, and

- a drive motor mechanically connected to the first and second support elements, and configured to allow cyclic movement of the first and second support elements between inactive and active positions. Such a manufacturing device allows the manufacture, by an end consumer, of a personalized cosmetic product from different capsules.

However, the structure of the manufacturing device described in the document FR3026622 requires the provision of a large drive motor in order to transmit, to the first and second deformable compartments, pressure forces suitable for ensuring the migration of the contents of the first compartment to the second compartment, and conversely a migration of the contents of the second compartment to the first compartment, and this in particular when the first and second deformable compartments or connecting channels associated with the first and second deformable compartments are closed by a weld zone weakened.

The provision of a large drive motor significantly increases the manufacturing costs of the manufacturing device, as well as the volume and weight of the latter.

In addition, the mixing of the capsules turns out to be more complex than expected and requires improvements both in terms of the material and the way the material is used.

PRESENTATION OF THE INVENTION

The present invention aims to remedy all or part of these drawbacks.

The technical problem underlying the invention therefore consists in providing an apparatus for manufacturing a composition which is simple, compact and easy to use, while having a simple structure and at a reduced price.

In particular, since the system is electrically powered, the presence of formulations or compositions, quasi-liquid and conductive of current, can pose problems in the event of leakage. Likewise, the location of the manufacturing device in a powder room poses potential short-circuit hazards that can damage components. In this regard, the invention provides a receiving device for forming a mixing machine when said receiving device is inserted into a manufacturing device, the receiving device comprising

- a first reception location, configured to receive a first capsule containing a first formulation,

a second reception location, configured to receive a second capsule containing a second formulation, the two capsules being able to be fluidly connected,

- a first actuation face,

- a second actuation face, opposite to the first actuation face,

- a heating element configured to heat at least one of the first and second capsules when the receiving device equipped with the first and second capsules is received in the mixing machine,

- a first electrical contact track for the electrical supply of the heating element, located on a first connection face of the receiving device,

- a second contact track for the electrical supply of the heating element, located on a second connection face of the receiving device.

In one embodiment:

the first connection face extends between, preferably connects, the first and the second actuation face of the reception device, and / or

- the second connection face extends between, preferably connects, the first and the second actuation face of the reception device.

In one embodiment, the connection faces are distinct from the actuation faces.

In one embodiment, the first and second connection faces are opposite one another. In one embodiment, the distance between the first and second connection faces is greater than the distance between the first and second actuation faces.

In one embodiment, the receiving device comprises an insertion face, through which the capsules can be inserted into their respective receiving location, and an opposite withdrawal face at the level of which the hinge is located.

In one embodiment, the electrical contact tracks are positioned in respective grooves.

In one embodiment, the first actuation face comprises a first support element and the second actuation face comprises a second support element.

In one embodiment, the reception device comprises a temperature sensor and two electrical contact tracks connected to the temperature sensor, the two electrical contact tracks being each positioned respectively on one of the connection faces.

In one embodiment, the actuation faces are opposite two by two and / or the connection faces are opposite two by two.

In one embodiment, the connection faces are distinct from the actuation faces. The invention also provides a mixing machine configured to receive a receiving device to form a manufacturing apparatus, the mixing machine comprising

a support defining a reception housing, typically capable of receiving a reception device as described above,

- an actuation system movable relative to the support inside the reception housing, comprising

^* A first actuating member positioned on one side of the receiving housing, and movable inside it, in order to transmit a pressure force on a first side of the receiving device or on the first capsule directly,

^* a second actuator, positioned on another side, preferably opposite, of the reception housing, and movable inside that, in order to transmit a pressure force on a second side of the reception device, or on the second capsule directly,

DETAILED DESCRIPTION

FIGS. 1A and 1B represent a manufacturing apparatus 2, according to a first embodiment of the invention, configured to manufacture a composition, which can for example be a cosmetic product, a hair care product, a pharmaceutical product, a phytosanitary product, a maintenance product, a cleaning product, or even an agrifood product. When the composition to be produced is a cosmetic product, the latter may for example be a homogenized emulsion, a homogenized solution or a mixture of several miscible phases.

The manufacturing apparatus 2 is intended for essentially personal use and on a small scale: it allows the preparation of a single portion ready for use.

Consequently, its dimensions must meet space constraints in a bathroom, a beauty salon, luggage (for transport), etc. Thus, the manufacturing apparatus 2 has no dimension greater than 40cm.

The manufacturing apparatus 2 comprises receiving means configured to receive first and second capsules 3, 4, also called pods or packaging units, respectively containing a predetermined amount of a first formulation and a predetermined amount of a second formulation , and a mixing machine 6 configured to mix the first and second formulations contained in the first and second capsules 3, 4 received in the manufacturing apparatus 2, so as to obtain a cosmetic product.

The mixing machine 6 comprises a receiving housing forming part of the receiving means, and which are designed to receive the first and second capsules 3, 4, directly or through a specific receiving device 5.

In a preferred embodiment and particularly visible in all of FIGS. 1A, 1B, 7A, 8A, 8B, 8C, the mixing machine 6 comprises a reception housing 32 capable of receiving a reception device 5 in a removable manner. The reception housing 32 in this case has a shape substantially complementary to that of the reception device 5.

The mixing machine 6 further comprises an actuation system 35 configured to exert a force on the first and second capsules 3, 4, via the receiving device 5 if necessary, to allow mixing and kneading of the composition to be to manufacture.

The receiving device 5, also called shuttle (because it serves as a vehicle for the first and second capsules 3, 4), preferably has a relatively symmetrical shape, either rectangular parallelepiped, or oval / ovoid. It is defined a longitudinal direction X, which corresponds to the direction in which it is inserted into the receiving housing 32. Consequently, the longitudinal direction X and the direction of insertion are merged when the receiving device 5 is inserted into the mixing machine 6.

Advantageously, the mixing machine 6 is configured to mix the first and second formulations inside the receiving device 5, and preferably inside the first and second capsules 3, 4, without any of the formulations being come into contact with the manufacturing device 2.

As indicated above, certain embodiments presented here are applicable to a manufacturing device 2 without receiving device 5, that is to say with first and second capsules 3, 4 directly positionable in the mixing machine.

Advantageously, the first formulation is a first phase of a cosmetic product to be produced, such as an oily phase of the cosmetic product, while the second formulation is a second phase of the cosmetic product, such as an aqueous phase of the cosmetic product. For example, the fatty phase can constitute the base of the cosmetic product to be produced, and the aqueous phase can comprise active elements and thus constitute a complex of active ingredients of the cosmetic product to be produced.

Capsules

The two capsules which can be used in the manufacturing apparatus 2 presented, are described in detail in the document filed under the application number FR 1755744 and the content of the description of the capsules being integrated here entirely.

The capsules as such are not the subject of the present invention. The following points will be retained for the remainder of the description.

As shown more particularly in FIGS. 2A, 2B, 3A, 3B, 4A, 4B, the first and second capsules 3, 4 are distinct from each other, and are configured to be fluidly connected to one another. other. In addition, each of the first and second capsules 3, 4 is advantageously for single use.

The first capsule 3 comprises a first deformable compartment 3.1, of domed shape, containing the first formulation, a first connection part 3.2 and a first connection passage 3.3 configured to fluidly connect the first deformable compartment 3.1 and the first connection part 3.2. Advantageously, the first connecting passage 3.3 is formed by a first connecting channel. The first connection part 3.2 more particularly comprises a female connection end piece 3.4, for example of cylindrical shape, fluidly connected to the first connection passage 3.3. The first capsule 3 comprises a flat face 3.7 through which the connection part 3.2 passes.

The first capsule 3 also comprises an outlet passage 3.5, such as an outlet channel, which is fluidly connected to the first connection passage 3.3, and which is provided with an outlet orifice 3.6. Advantageously, the outlet passage 3.5 extends in the extension of the first connection passage 3.3, and substantially parallel to the first connection passage 3.3. In the present case, the outlet passage 3.5 can be indifferently mounted on the first capsule 3 or on the second capsule 4. In fact, the outlet passage 3.5 is requested in operation only after the manufacturing device 2 has been used.

The second capsule 4 comprises a second deformable compartment 4.1, of domed shape, containing the second formulation, a second connection part 4.2 configured to be connected to the first connection part

3.2, and a second connection passage 4.3 configured to fluidly connect the second deformable compartment 4.1 and the second connection part 4.2. Advantageously, the second connection passage 4.3 is formed by a second connection channel, and the second connection part 4.2 extends substantially perpendicular to the second connection passage

4.3. The second connection part 4.2 more particularly comprises a male connection end piece 4.4, for example of cylindrical shape, fluidly connected to the second connection passage 4.3 and configured to receive the female connection end piece 3.4 in a sealed manner. The second capsule 4 comprises a flat face 4.7 through which the second connection part 4.2 passes.

The first and second capsules 3, 4 and more particularly the first and second deformable compartments 3.1, 4.1 are each closed by connection welds ensuring the tightness of the first and second capsules 3, 4, these connection welds being breakable as soon as a threshold pressure is reached. These threshold pressures can be reached in the mixing machine 6. Again, these connection welds are described in detail in the description of the document filed under the application number FR 1755744

Each of the first and second capsules 3, 4 is configured to contain all or substantially all of a mixture formed by the predetermined amount of the first formulation and the predetermined amount of the second formulation. In this respect, either the deformable compartments are flexible, or buffer zones are provided. Again, the description of the document filed under the application number FR 1755744 describes this precisely. The receiving device

As shown more particularly in FIGS. 2A, 2B, 3A, 3B, 4A, 4B and 5 the receiving device 5 is able to occupy an open position in which the first and second capsules 3, 4 are able to be introduced into the device 5, and a closed position in which the receiving device 5 is able to hold the first and second capsules 3, 4 in position.

The reception device 5 more particularly takes the form of a reception box 7 (FIGS. 2A, 2B) configured to receive and at least partially house the first and second capsules 3, 4. The reception device 5 comprises in particular a first protective shell 8 and a second protective shell 9 mounted articulated with respect to each other about a hinge pin 10 (or hinge) and between a corresponding first position (see FIGS. 2A, 2B, 5) in an open position of the receiving device 5 and a second position (see FIGS. 4A, 4B) corresponding to a closed position of the receiving device 5. The receiving device 5 further comprises a first support part 1 1 and a second part support 12 disposed in the receiving housing 7. The first and second support portions 1 1, 12 respectively have a first receiving location 13 configured to receive the first capsule 3 and a second location. receiving cement 14 configured to receive the second capsule 4. The first and second protective shells 8, 9 each have an opening 8.2, 9.2 to allow access to the first or second receiving location 13, 14. These openings 8.2, 9.2 define an insertion face of the receiving device 5. The receiving device 5 comprises a withdrawal face, opposite the insertion face.

Advantageously, the first support part 1 1 comprises receiving shims 15 configured to receive a peripheral portion of the first capsule 3, and the second support part 12 also comprises receiving shims 15 configured to receive a peripheral portion of the second capsule 4. These receiving blocks 15 partially define the first and second receiving locations 13, 14.

The first support part 1 1 comprises a first placement surface

1 1 .1, configured to guide (with contact) and receive the planar face 3.7 of the first capsule 3. The first placement surface 1 1.1 therefore partially defines the first receiving location 13.

Similarly, the second support part 12 comprises a second placement surface 12.1, configured to guide (with contact) and receive the planar face 4.7 of the second capsule. The placement surface 12.1 therefore partly defines the second receiving location 14.

When the first and second capsules 3, 4 are inserted, their respective flat faces 3.7, 4.7 are turned towards one another, with the two placement surfaces 1 1 .1, 12.1 between them.

In order to allow the passage of the first and second connection parts 3.2, 4.2 of the first and second capsules 3, 4, the first and second placement surfaces 1 1 .1, 12.1 each comprise a passage opening 1 1 .2,

12.2, in the form of a slit, open towards the outside, along an insertion axis X

(Figure 1A).

The receiving device 5 further comprises a separation wall 22, defining a separation plane (FIGS. 3A, 3B). The partition wall 22 is located between the first and second receiving locations 13, 14. It is also integral with the first support part 11. The partition wall 22 includes a passage opening 22.2 in order to allow the first and second connection parts 3.2, 4.2 to be positioned in the receiving device. The passage opening 22.2 is in the form of a through slot on the thickness and open to the outside.

The openings 1 1 .2, 22.2, 12.2 therefore form a space for receiving the connection ends 3.4, 4.4 of the first and second capsules 3, 4. A first actuating face 8.1 which comprises the first shell 8 and the first support part 11 and a second actuating face 9.1 which comprises the second shell 9 and the second support part 12 is also defined.

Each actuating face 8.1, 9.1 is involved in the transmission of the forces received by the receiving device 5 to the first and second capsules 3, 4. This will be explained in detail below.

Joint

According to the embodiment visible in FIGS. 2A, 2B, 3A, 3B, 5, the first and second shells 8, 9 are articulated relative to each other around the axis of articulation 10 and between a receiving position (see Figures 2A, 2B, 3A, 3B) in which the first and second shells 8, 9 are spaced from each other and the first and second capsules 3, 4 are adapted to be received respectively in the first and second receiving locations 13, 14, and a connection position (see FIGS. 4A, 4B) in which the first and second shells 8, 9 are brought together and the first and second capsules 3, 4 are pre-connected to each other. By pre connected to each other is meant that the male connection end piece 4.4 of the second capsule 4 is partially introduced into the female connection end piece 3.4 of the first capsule 3 without, however, a tight connection being established between these first and second capsules 3, 4.

The first and second shells 8, 9 can for example have an angle of inclination greater than or equal to 7 °, and for example of about 7 °, when they are in the receiving position, and be substantially parallel one relative to each other when in the connection position. More specifically, there are two main assemblies only articulated with respect to one another: the first shell 8, the first support part 11, the partition wall 22 and the second support part 12 on the one hand; and the second hull 9, on the other hand.

Advantageously, the first and second shells 8, 9 (or the actuating faces 8.1, 9.1) are configured to engage the first part of connection 3.2 in the second connection part 4.2 when the receiving device 5 is moved to the closed position. Indeed, when the first and second shells 8, 9 are in the closed position, the connection parts 3.2, 4.2 are partially fitted together.

The first and second support parts 1 1, 12 are more particularly configured so that the first and second capsules 3, 4 extend substantially parallel to one another, when the first and second shells 8, 9 are in the connection position. As shown in FIGS. 4A, 4B, the first capsule 3 is configured to extend partly outside the reception device 5 when it is received in the reception device 5 and when the latter is in the closed position . Advantageously, the outlet port 3.6 is configured to extend outside the receiving device 5 when the first capsule 3 is received in the receiving device 5 and the latter is in the closed position.

The heating element

The manufacturing apparatus 2 comprises a heating element 46 (also called "heating element") visible in FIGS. 3A, 3B. In the embodiment illustrated in the figures, the heating element 46 is part of the receiving device 5. However, in the absence of receiving device 5, the latter could be integrated into the mixing machine.

The heating element 46 is attached to the partition wall 22. During the design, it was chosen that the heating element 46 is on the side of the first support part 1 1, which means that the element heater 46 is mounted on the side of the partition wall 22 which is on the side of the first support part 1 1.

The heating element 46 preferably comprises one or more electric heating resistors 46.1 and a diffusion plate 46.2. The heating element 46 thus has a planar shape to better distribute the heat, if possible with an area of at least 500 mm 2 and preferably of the order of 800 mm ² . However, as between the first capsule 3 and the heating element 46 is the first support part 11, there is provided in the first support part 11 a communication opening 46.3 which places the planar face 3.7 of the first in direct communication capsule 3 with the heating element 46 (that is to say separated only by air).

The electrical contact tracks of the heating element

The heating element 46 needs to be supplied with electricity. Preferably, the receiving device 5 does not have its own battery and must be powered when it is inserted in the receiving housing 32.

Consequently, an electrical connection is provided between the receiving device 5 and the mixing machine 6. The receiving device 5 comprises the insertion face, where the openings 8.2, 9.2 are located and which is the face which enters the first in the receiving housing 32, and an opposite withdrawal face, which is the visible face when the receiving device 5 is inserted in the receiving housing 32. The receiving device 5 further comprises a first actuating face 8.1 and a second actuating face 9.1, opposite.

Finally, the connection device 5 comprises a first connection face 23 and a second connection face 24, preferably opposite. In the embodiment illustrated in FIGS. 2A, 2B, 3A, 3B, 4A, 4B, the connection faces 23 and 24 correspond to lateral faces of the heating element 46 and are therefore distinct from the first and second faces d 8.1, 9.1 and insertion / withdrawal faces.

The connection faces 23, 24 extend between the actuating faces 8.1, 9.1 of the receiving device 5. Preferably, the connecting faces 23, 24 connect the actuating faces 8.1, 9.1 of the receiving device 5 to one another. , that is, they are contiguous.

The general shape of the receiving device 5 is chosen so that the connection faces 23, 24 are more spaced apart than the actuating faces 8.1, 9.1 (and than the insertion / withdrawal faces). In other words, if we take the smallest parallelepiped in which the receiving device 5 is inserted, the faces which touch the connection faces 23, 24 are more distant than the faces which touch the actuating faces 8.1, 9.1 and are closer than the faces which touch the insertion / withdrawal faces. This results in the fact that the receiving device 5 is wider than thick (and moreover it is taller than wide).

The first connection face 23 comprises a first electrical contact track 23.1 intended to supply the heating element 46 and the second connection face 24 comprises a second electrical contact track 24.1 intended also to supply the heating element 46 (FIGS. 2A, 3A, 3B, 4A, 4B). The electrical contact tracks 23.1, 24.1 are therefore outside the receiving device 5, in order to be brought into contact with complementary tracks (FIGS. 2A, 4A, 4B).

This configuration has several advantages: first, it ensures a simple and efficient electrical connection. It also avoids the risks of short circuit. Indeed, if ever liquid were to flow into the receiving housing 32 (for example water from the shower or the sink or simply a capsule which bursts), it is unlikely that the two electrical contact tracks 23.1 , 24.1 are affected at the same time by the same volume of liquid.

The first connection face 23 comprises a portion of the first and second shells 8, 9, of the first support part 11 and of the partition wall 22.

In particular, the first connection face 23 comprises a longitudinal groove 23.2 with a bottom 23.21 and two side walls 23.22, 23.23. The first electrical contact track 23.1 is preferably positioned on the side wall 23.22 of the longitudinal groove 23.2. In the embodiment illustrated in FIGS. 3A, 3B, the bottom 23.21 and the side wall 23.23 are produced by a portion of the first support part 11. An adapted cutout 8.5 is then provided in the first shell 8 to make room for the longitudinal groove 23.2. The opposite side wall 23.22 is produced by a portion of the partition wall 22. The first electrical contact track 23.1 is then positioned on this side wall 23.22 (because the heating element 46 is mounted on the partition wall).

In the same way, a similar longitudinal groove 24.2 is provided on the second connection face 24, with a cutout 9.5 in the second shell 9 and a bottom 24.21 and two opposite side walls 24.22, 24.23. Due to the non-centering of the grooves, the cutout 9.5 in the second shell 9 is significantly less marked than the cutout 8.5 in the first shell 8.

The grooves 23.2, 24.2 are configured to engage on respective complementary rails 31 .1, 31 .2 (sliding link) provided in the receiving housing 32 on (preferably opposite) connection sides (Figures 1A, 7A). Consequently, the grooves 23.2, 24.2 form undercuts which extend over the entire height of the portion of the receiving device 5 where they are located - at least up to the insertion height. The complementary rails 31 .1, 31 .2 contribute to defining the receiving housing 32 and are positioned on opposite edges.

In an embodiment visible in FIGS. 4A, 4B in particular, the electrical contact tracks 23.1, 24.1 are not located at the same level, but are offset.

The electrical contact tracks 23.1, 24.1 can take several forms: electrical pins, metal blades (as illustrated), etc. The electrical contact tracks 23.1, 24.1 are preferably slightly deformable to ensure permanent contact when the reception device 5 is placed in the reception housing 32.

It is thus noted that the longitudinal grooves 23.2, 24.2 are not centered relative to the first and second actuation faces 8.1, 9.1 (see in particular Figures 2A, 4A, 4B). In terms of design, this results in a groove essentially formed in the first support part 11 and the first protective shell 8.

The interest in this asymmetry lies in a keying function. It is indeed impossible to put the receiving device 5 in the wrong direction (depending a 180 ° rotation around the longitudinal axis X) because the grooves 23.2, 24.2 would not fit into the rails 31 .1, 31.2 and the second shell 9 would come into abutment against these.

In order to have a polarizing effect for vertical rotation (i.e. by trying to put the withdrawal face first instead of the insertion face), the longitudinal grooves 23.2, 24.2 do not extend over the entire height of the portion of the first or second shell 8, 9 where they are located. Therefore, without necessarily providing a specific part, a stop effect is obtained simply by the part of the first or second shell 8, 9 which does not pass through the draft effect. In other words, the first or second shell 8, 9 prevents the insertion of the grooves 23.2, 24.2 on the rails 31 .1, 31.2 when the receiving device 5 is in the wrong direction.

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

In reality, it has two different types of stops, but they are located substantially in the same place: at the end of the longitudinal grooves 23.2, 24.2.

The electrical contact tracks of the temperature sensor

The first support part 1 1 is preferred to the second support part 12 for carrying a wall 23.23, 24.23 of the groove 23.2, 24.2, because of the heating element 46 which is intended to heat mainly the first capsule 3.

In fact, a temperature sensor (not visible in the figures) is attached to the rear face of the diffusion plate 46.2 to measure the temperature prevailing near the first receiving location 13 and therefore the first capsule 3. The temperature sensor is typically a NTC (Negative Temperature Coefficient thermistor).

This temperature sensor 6 must also be electrically connected to the mixing machine 6 (in particular in fine the processor, for recovering the data) and to a battery 44 equipping the mixing machine 6, to supply it. To this end, a first additional electrical contact track 46.51 is provided at the level of the first contact face 23. This first additional electrical contact track 46.51 is separate from the first electrical contact track 23.1. More specifically, the first additional electrical contact track 46.51 is provided in the first groove 23.2, on the side wall 23.23, that is to say the side wall formed by the first support part 11.

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

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

Figures 2A, 3A, 3B, 4A, 4B, 5 illustrate these tracks.

The key

The receiving device 5 includes a keying device 17 to ensure that the first and second capsules 3, 4 are correctly positioned, that is to say that the "good" capsules 3, 4 are placed in the "good" locations reception 13, 14 (clearly visible in FIGS. 2A, 5). The keying device 17 is preferably located at the end of the passage openings 1 1 .2, 12.2, to block the unwanted passage of an unwanted connection endpiece 3.2, 4.2. The key 17 comprises at least one leaf 17.1 opening towards the outside of the receiving device 5 (preferably two, on each side as illustrated in the figures; preferably, the two leaves 17.1 have a saloon configuration, that is to say - say articulated by hinges towards the outside of the receiving device 5).

In particular, the key 17 fulfills two distinct roles.

The leaf 17.1 includes an opening 17.2 of complementary shape to the female connection end piece 3.4 of the first capsule 3 in order to allow its insertion into the opening 8.2. In addition, the leaf 17.1 includes a stop 17.3, which contributes to defining the opening 17.2, in order to prevent the insertion into the opening 8.2 of the second connection part 4.2, longer transversely than the first connection part 3.2 . Indeed, if we try to insert the second capsule 4 in the first receiving location 13, the end of the second connection part 4.2, that is to say part of the male connection end piece 4.4 comes knock against the stop 17.3.

For access to the second receiving location 14, the polarizing device 17 blocks it when the receiving device 5 is in the closed position: the passage opening 12.2 is blocked, preferably by the stop 17.3 also. On the other hand, when the receiving device 5 is in the open position, that is to say that the second shell 9 has turned on its hinge, the passage opening 12.2 is released.

Finally, as the leaf 17.1 opens towards the outside, it is functionally non-blocking during the extraction of the first and second capsules 3, 4 (both at the same time because they are attached) from the reception device 5.

The key 17 can be attached to the first support part 11 or to the second support part 12 (as in the figures), depending on the design of the relative movement of the parts: if the second support part 12 is attached to the second shell 9 (and therefore movable in rotation relative to the first support part 1 1), then it is preferable to attach the polarizing element to the first support part 1 1. In other words, this is indifferent. Return springs 17.4 keep the key 17 in the default position, that is to say closed.

Supporting elements - pallets

As shown in particular in FIGS. 2B, 3A, 3B, 5 the reception device 5 also comprises a first support element 19 configured to penetrate inside the second reception location 14, that is to say for exert a pressure force on the first capsule 3, and more particularly on the first deformable compartment 3.1, and a second support element 21 configured to penetrate inside the first receiving location 13, that is to say to exert a pressure force on the second capsule 4, and more particularly on the second deformable compartment 4.1.

The first support element 19 (respectively the second support element 21) is preferably mounted on the first support part 11 (respectively the second support part 12) and is movable between an inactive position, or said deployed position, in which the first or second receiving location 13, 14 is accessible for the first or second capsule 3, 4 (see FIG. 2B, 3A, 3B) and an active position or said folded position, in which the first support element 19 (respectively the second support element 21) penetrates inside the first receiving location 13 (respectively the second receiving location 14), that is to say it is able to exert a pressure force on the first deformable compartment 3.1 of the first capsule 3 (respectively the second deformable compartment 4.1 of the second capsule 4).

The first support element 19 (respectively the second support element 21) is advantageously mounted mobile in rotation around a hinge 19.1 (respectively the hinge 21.1). The hinge 19.1 (respectively the hinge 21 .1) is located opposite the opening 8.2 (respectively the hinge 8.1) of the first shell 8 (respectively the second shell 9). The hinges 19.1, 21.1 are therefore both located near the withdrawal face of the receiving device 5. The support elements 19, 21 each have a flat internal face 19.2, 21 .2 to form pallets which are mobile in rotation. Each planar internal face 19.2, 21 .2 cooperates with its first or second capsule 3, 4 respectively. As the support elements are pressed, the volume between the pallet and the placement surface 1 1 .1, 12.1 decreases progressively and continuously. When the first or second capsule 3, 4 is installed, the outlet orifice 3.6 and the connection parts 3.2, 4.2 are located on the side opposite to the hinge 10: this makes it possible to effectively remove the cream from the first or second capsule 3 , 4 by avoiding any unwanted retention zone inside it.

To hold the support elements 19,21 in the open position by default (that is to say when the receiving device 5 is not actuated or when the second shell 9 is in the pivoted position), return means 21 .3, like springs, are provided, bearing against the first or second shell 8, 9 (FIG. 5). The return means 21 .3 may tend to push the pallet which extends slightly on the other side of the hinge 21.1.

In use, as will be described later, the two support elements 19, 21 are activated successively to allow the mixing of the cream. The cream then passes from a first or second capsule 3, 4 to the other second or first capsule 4, 3.

Preferably, to optimize the operation of the pallet, the hinge 19.1 (respectively the hinge 21.1) defines an axis of rotation included in the plane of the placement surface 1 1 .1 (respectively the placement surface 12.1) and orthogonal to the longitudinal axis of the receiving device 5. In the absence of a capsule, the internal face 19.2, 21.2 can be pressed against the placement surface 1 1 .1, 12.1.

Likewise, the hinge 19.1, 21 .1 is preferably located just at the end of the first or second receiving location 13, 14.

In order to move the support elements 19, 21, the first and second shells 8, 9 each comprise, preferably facing the extremal part of the pallet (to take advantage of the leverage and minimize the effort to be applied) , a support point 8.3, 9.3, configured to receive an external force, described in more detail below. The support point 8.3, 9.3 is attached to a flexible zone 8.4, 9.4, which can deform (into an elastomer, etc.). The flexible zone 8.4, 9.4 is itself attached to the rest of the first or second shell 8, 9, made of a more rigid plastic.

The support point 8.3, 9.3 is made of a rigid material (typically plastic). Alternatively (not shown), the first and second shells 8, 9 have two orifices, preferably facing the extremal part of the pallet, in order to allow free access to the support elements 19, 21.

A user can, with one hand, grasp the receiving device 5 and press on the support points 8.4, 9.4 simultaneously, for example with the thumb and index / middle finger. Simultaneous pressure directs the cream from the first and second capsules 3, 4 to the outlet 3.6.

In another embodiment not shown, where the receiving device 5 is integrated into the mixing machine 6, the pallets can be directly integrated into the mixing machine 6.

The retention stop

In order to prevent the receiving device 5 from being withdrawn from the receiving housing 32 when the mixing process is in progress, a retention mechanism 50, described in detail below, is provided in the manufacturing apparatus 2. For that the retention mechanism 50 has a grip on the receiving device 5, a retention stop 9.6 is provided on one of the first or second shells 8, 9 (the second shell 9 in FIGS. 2A, 2B, 3A, 3B, 4B , 5). This retention stop 9.6 essentially corresponds to a projection extending radially, that is to say in a plane orthogonal to the longitudinal direction X. It can be at any location along the height of the device. reception 5. In the illustrated embodiment, the retention stop 9.6 is arranged near the insertion face.

Another stop can be provided on the other shell, for ergonomic reasons for example. Gripping handles

In order to allow the user to grasp the receiving device 5 when it is inserted into the receiving housing 32, grip handles 8.7, 9.7 are provided on each of the first and second protective shells 8, 9 (visible in particular in FIGS. 1, 2B, 4A, 4B). These gripping handles 8.7, 9.7 are located at the level of the withdrawal face, which is the one accessible when the receiving device 5 is in place.

The gripping handle 8.7, 9.7 may simply consist of a projection extending radially, that is to say in a plane orthogonal to the longitudinal direction X, long enough for part of the phalanx of the user can shoot at it.

The coupling button

As indicated above, the actuating faces 8.1, 9.1, and more specifically the first and second protective shells 8, 9 each comprise a support point 8.3, 9.4, for transferring the force towards the support elements 19, 21 inside. These support points 8.3, 9.4 are formed in a flexible zone 8.4, 9.4.

When the receiving device 5 goes into the closed position, the connection ends 3.4, 4.4, come opposite one another and partially fit together. To create a tight and reliable fluid communication between the first and second capsules 3, 4, a coupling mechanism 52 is provided in the manufacturing apparatus 2. This coupling mechanism 52 exerts a force in the direction of the receiving device 5. This coupling mechanism 52 makes it possible both to establish the fluid connection between the first and second capsules 3, 4 under the effect of the force exerted by the coupling mechanism 52 but also to avoid any unwanted disconnection first and second capsules 3, 4 under the effect of the pressures generated by the kneading of the first and second capsules 3, 4. It will be described below. One of the first or second protective shells 8, 9 (or both), comprises a coupling button 9.8, movable in the direction of the second receiving location 14 (FIGS. 2A, 2B, 3A, 3B, 4A, 4B, 5) . More specifically, it is movable towards an area close to the opening 9.2, since the coupling button 9.8 is intended to press on the second capsule 4 near the connection portion 4.2. In this regard, the coupling button 9.8 is attached to a flexible zone, which can be the flexible zone 9.4 of the support point 9.3. We note here that the coupling button 9.8 is distinct from the support point 9.3.

The coupling button 9.8 is preferably rigid to better transmit the force of the coupling mechanism 52 to the first and second capsules 3, 4, which are therefore kept coupled.

The mixing machine

As shown more particularly in FIGS. 6, 7A, 7B, 8A, 8B, 8C, 9, 10A, 11 A, 11 B, 11 C, the mixing machine 6 comprises a support 31, and a receiving housing 32 defined in at least in part by the support 31 and configured to receive at least in part the receiving device 5. According to the embodiment shown in FIGS. 1A, 1B, the mixing machine 6 and the receiving device 5 are configured in such a way so that the reception device 5 extends at least in part outside the mixing machine 6, when the reception device 5 is received in the reception housing 32.

The support 31 behaves like a base, that is to say it defines a set of fixed elements when the mixing machine 6 is placed on a support (table, worktop, ...), little matters whether it is in use or not. The support 31 of the mixing machine 6 also includes an external shell 33 and an insertion opening 34 opening into the reception housing 32, the reception device 5 being configured to be inserted into the reception housing 32 through the insertion opening 34. Advantageously, the insertion opening 34 is formed in a central portion of an upper surface of the base 33, and is configured to be oriented upwards when the mixing machine 6 is arranged on a horizontal support surface (table, work surface, etc.).

The base 33 also acts as an outer envelope, with the desired design for the mixing machine. The base 33 may include a lower base and an upper base.

The actuation system

The mixing machine 6 furthermore comprises an actuation system 35 pivotally mounted on the support 31 around a substantially vertical pivot axis 36 when the mixing machine 6 is placed on a horizontal support surface (table, worktop , ...) (Figures 6, 8A, 8B, 8C, 9, 10A).

Preferably, the actuation system 35 performs back and forth movements around the pivot axis 36 with a maximum angular movement of 45 °. The movement is therefore composed of a rotation at + 45 ° C maximum then a rotation at -45 °, and so on. Its displacement is made according to a nominal stroke C35 (not shown in the figures), which, in the case of rotation around the pivot axis 36, is associated with the maximum angular movement. The nominal travel C35 of the actuating system 35 is defined as the travel between two extreme positions of said actuating system 35. A neutral position of the actuating system 35 is defined between these two extreme positions, the neutral position of the actuation 35 corresponding to an insertion position in which the receiving device 5 can be positioned inside the receiving housing 32 of the mixing machine 6 without being hindered by the actuating system 35.

The mixing machine 6 further comprises a drive motor 39 mounted on the support 31. The drive motor 39 is configured to pivot the actuation system 35 around the pivot axis 36 and within an angular range predetermined. Preferably, the drive motor 39 only rotates in one direction.

The actuating system 35 comprises a first actuating member 37, which may include a first actuating finger 37.1, configured to transmitting a pressure force to the first capsule 3, and a second actuating member 38, which may include a second actuating finger 38.1, opposite to the first actuating member 37 and configured to transmit a pressure force to the second capsule 4.

The first and second actuating members 37, 38 are configured to be arranged on either side of the reception housing 32 and therefore of the reception device 5 when the latter is received in the mixing machine 6, and more precisely in the reception housing 32.

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

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

An actuating stroke C37 is defined for the first actuating member 37 and an actuating stroke C38 for the second actuating member 38.

The actuating stroke C37 is defined as the stroke of the first actuating member 37 between the neutral position of the actuating system 35 and the maximum actuating position of the first actuating member 37, in which the first actuating member actuation 37 is in maximum compression on the first support element 19. Conversely, the actuating stroke C38 is defined as the stroke of the second actuating member 38 between the neutral position of the actuating system 35 and the maximum actuating position of the second actuating member 38, in which the second member actuation 38 is in maximum compression on the second support element 21.

Preferably, the movement of the actuation system 35 can be monitored using various sensors, and in particular Hall effect sensors. More specifically, each of said first actuating member 37 and second actuating member 38 may include a magnet intended to interact with a fixed Hall effect sensor. Advantageously, the Hall effect sensor can be directly placed on a control unit 45 which will be described later, as can be seen in FIG. 12. It is thus possible for the control unit 45 to follow the movement of the actuation system 35, and even of each of the first and second actuation member 37, 38. It is even conceivable, for the control unit 45, to know precisely the position of each of the first and second actuation member. actuation within their respective actuation strokes C37, C38, for example by having several Hall effect sensors.

According to the embodiment shown in FIGS. 1 to 22, the first and second actuating members 37, 38 extend substantially in the same extension plane, and converge opposite the pivot axis 36.

As illustrated in FIGS. 6, 8A, 8B, 8C, 9, the actuation system 35 has a substantially annular shape defining an opening around the reception housing 32. In one embodiment, the actuation system 35 is formed essentially in one piece, comprising an opening for receiving a shaft defining the pivot axis 36.

The first actuating member 37 and the second actuating member 38 are each disposed on opposite sides of the actuating system 35. Consequently, there is an actuating system 35 extending twice over two opposite sides two to two: the actuators 37, 38, the opening for the pivot axis 36 and the drive mechanism with groove which is described below.

The actuating members 37, 38 may each comprise a drive support 37.3, 38.3, which meet on one side at the level of the pivot axis 36. On the other side, a connection portion 36.1 is defined. , which connects the two drive supports 37.3, 38.3. The connection portion 36.1 can be attached or come in one piece with the drive supports 37.3, 38.3.

Preferably, the two actuating members 37, 38 rotate around the same pivot axis 36. In this case, we prefer two drive supports 37.3, 38.3 integral in rotation.

However, it is possible to provide a pivot axis for each of the actuating members 37, 38; however, some simple adaptations will have to be made.

Alternatively, in an embodiment not shown, the actuating members are movable in translation.

Springs

The actuation system 35 moves along a nominal stroke C35 to exert a force on the receiving device 5.

However, the games in the kinematic chain, linked to manufacturing tolerances, can disturb the transmission of forces by shifting the positioning of the actuating system 35. Thus, once the end of travel is reached, it may be missing a few millimeters or conversely that there are a few millimeters extra. This can cause insufficient compression or, conversely, break the manufacturing device 2.

To overcome this, the actuation system 35 may include a spring 37.4, 38.4 (particularly visible in Figures 8A, 8B, 8C). In particular, the spring 37.4, 38.4 is configured to compress when the actuation system 35 arrives in the vicinity of its nominal end of travel C35 and that the actuating finger 37.1, 38.1 abuts against the flat face 3.7, 4.7 of the capsule. The spring 37.4, 38.4 therefore generates a force tending to move the actuating member 37, 38 away from the receiving device 5.

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

The spring 37.4, 38.4 can be located in different places. In an embodiment not illustrated, the spring 37.4, 38.4 is located at the "free" end of the finger 37.1, 38.1.

In another embodiment, preferred because the spring is hidden, the spring 37.4, 38.4 is mounted between the finger 37.1, 38.1 and the drive support 37.3, 38.3. In this way, the user cannot access it because the spring is behind the base.

To put the spring in this location, it is convenient to provide for each actuating member 37, 38 an arm 37.2, 38.2, mounted movably relative to the drive support 37.3, 38.3. The finger 37.1, 38.1 is then mounted integrally on the arm 37.2, 38.2.

In the embodiment illustrated in particular in FIGS. 8A, 8B, 8C, 9, the arm 37.2, 38.2 is movable in rotation relative to the drive support 37.3, 38.3 by a hinge 37.5, 38.5. The spring 37.4, 38.4 is positioned between the arm 37.2, 38.2 and the drive support 37.3, 38.3.

The spring 37.3, 38.3 therefore works in compression, in the sense that its empty position, or unconstrained position, is not compressed. It is compressed in the direction of translation or rotation of the actuating member 37, 38.

The spring 37.3, 38.3 may be of the helical, leaf type, or even comprises an elastic material or an elastic assembly (elastomer, gas bubble, etc.).

Rotational training

According to the embodiment shown in Figures 6, 8A, 8B, 8C, 9, the mixing machine 6 also includes a cam 41, in the form of a wheel drive or an arm, integral in rotation with an output shaft 39.1 of the drive motor 39 and configured to be driven in rotation about its axis 41 .1 of cam rotation. The cam 41 is mounted on the support 31. To allow the back-and-forth movement with a large lever arm, it is preferable that the pivot axis 36 and the cam 41 are on either side of the receiving housing 32.

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

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

The drive finger 42 is received in a drive groove 43 provided on the actuation system 35. In particular, the drive groove 43 is constructed in the connection portion 36.1. The drive groove 43 is elongated and extends in an extension direction substantially parallel to the pivot axis 36. Such a configuration of the mixing machine 6 makes it possible to obtain an alternating movement of the actuation system 35 by rotating the drive motor 39 always in the same direction of rotation, so that it is not necessary to use an expensive control system for the drive motor 39.

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

Now, the connection between the drive groove 43 and the drive finger 42 will be described. Given the rotation of the actuation system 35, the alignment of the drive groove 43 and the drive finger 42 is variable, which means that a simple adjustment would block the system. Conversely, the presence of play, which would allow misalignment, generates noise and gives a delay time at each end of the race. To resolve this, a ball joint is provided between the drive finger

42 and the drive groove 43, which makes it possible to manage the previous misalignment.

In particular, on the drive finger 42 is mounted a ball 42.1, which is housed in a ring 43.1. The connection between the ball 42.1 and the ring 43.1 is a ball joint. The ring 43.1 is received in the drive groove

43 where it is mounted movable in translation in a direction parallel to the pivot axis 36 (therefore along the length of the drive groove 43). Finally, the ball 42.1 is mounted movable in translation along the drive finger 42. The arrangement of these different connections can be different, in the sense that the ring can also be movable in translation along the depth of the groove and the ball is then fixed on the training finger.

Consequently, the complete connection between the drive finger 42 and the actuation system 35 comprises in series a slide, a ball joint, a slide perpendicular to the other slide. Consequently, in a kinematic torsor, it is noted that the force is transmissible only on one of the six components of the torsor, namely that of the translation tangent to the rotational movement of the actuation system 35, that is to say -to say the one that allows the actuation system 35 to rotate. The kinematic equivalent is the sphere-plane connection (also called a point connection).

So that the connection described above is not unnecessarily more complex, the cam rotation axis 41.1 and the pivot axis 36 are preferably orthogonal. This makes it possible to have a drive finger 42 which describes a circular movement in a plane parallel to the pivot axis 36.

Certain planned movements of the connections can be made simply by plastic / plastic sliding, the wear of which is sufficiently slow to ensure a satisfactory service life.

According to an alternative embodiment of the invention, the mixing machine 6 could be configured so that a rotation of the drive motor 39 in a first direction of rotation causes the actuating part 35 to pivot in a first direction of rotation and that a rotation of the drive motor 39 in a second direction of rotation, opposite to the first direction of rotation, causes a rotation of the actuating part 35 in a second direction of pivoting, opposite to the first direction of pivoting.

Offset of the pivot axis

The actuating members 37, 38 each move according to an actuating stroke C37, C38.

However, in the embodiment illustrated in the figures, one of the two actuating members 37, 38 has an actuating stroke C37, C38 of length strictly greater than that of the other actuating member.

This difference in actuation stroke C37, C38 makes it possible to better manage mechanically and electrically the force to be provided to deform the first capsule 3 relative to the second capsule 4. In fact, as illustrated in FIG. 2B, the first capsule 3 has a thickness greater than the second capsule 4, which means that more space is needed on the side of the thicker capsule and that the support element 19 will be more rapidly in contact and will start to work faster than the support element 21.

To achieve this difference in travel, several solutions are possible. One solution is to have a drive groove 43 not centered in the connection portion 36.1.

Another solution, illustrated in particular in FIGS. 8A, 8B, 8C, 9 consists in decentering the pivot axis 36. In other words, the cam rotation axis 41.1 does not overlap the pivot axis 36. This induces a difference in travel between the two actuating members 37, 38 when the cam 41 completes one revolution. A distance (orthogonal, i.e. by orthogonal projection) between the cam rotation axis 41.1 and the pivot axis 36 from 1% to 5% of the distance between the driving groove 43 and l pivot axis 36 is sufficient and does not disturb the symmetrical appearance of the assembly too much. In absolute terms, a distance between 1 and 2mm is suitable. The offset can also be defined using the receiving housing 32 relative to the axis of rotation of the cam 41: thus the extreme positions of the actuating system 35 are not centered around the receiving housing 32.

The offset can also be defined relative to the first and second placement surfaces 1 1 .1, 12.1 or relative to the location of the first and second capsules 3, 4 within the receiving housing 32: using the faces planes 3.7, 4.7, which therefore define artificial planes in the receiving housing 32. The maximum distance from the first actuating member 37 to said plane of the planar face 3.7 is greater than the maximum distance from the second actuating member 38 relative to on the flat face 4.7.

In this regard, in a variant, the pivot axis 36 is included in a plane located equidistant from the two placement surfaces 1 1 .1, 12.1.

In reaction to the shift, the first actuating finger 37.1 is advantageously longer than the second actuating finger 38.1. This is in particular due to the fact that it is necessary to compensate for the extreme position of the actuating fingers 37.1, 38.1 due to the shift. More precisely, the actuator must 37.1, 38.1 which works on the first or second capsule 3, 4 thickest, has a greater length than the other actuating finger 38.1, 37.1.

Another solution, which is illustrated in FIG. 8A, consists in not defining the neutral position of the actuation system 35 during a top or bottom dead center of the cam 41. Indeed, by choosing the neutral position of the actuating system 35 at a non-zero angle Ag (typically Ag is between 5 ° and 30 °) with respect to noon (when the mixing machine 6 is placed on a horizontal support) , the distribution of the actuating strokes C37, C38 is shifted. We also note that we obtain in fact another neutral position for an angle Ag ’corresponding to Ag’ = 180 ° -Ag.

Actually, the actuating strokes C37, C38 correspond, at the level of the cam 41, to the rotation from said angle Ag to the nearest 90 ° rotation (that is to say 3h or 9h, when the mixing machine 6 is placed on a horizontal support) and then rotation from said angle Ag 'until rotation at 270 °. As Ag and Ag 'are not at 0 and 180 ° (noon and 6h), we immediately notice that the races C37 and C38 are not equal. On a complete rotation of the cam 41, the first actuation stroke C37 has therefore been traversed in a first direction, then the first actuation stroke C37 in a second direction, then the second actuation stroke C38 in a first direction and then the first actuation stroke C38 in a second direction, that is to say twice the nominal stroke C35.

Contact tracks of the mixing machine

As mentioned previously, the mixing machine 6 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 contact tracks electrical 31.51, 31.52 configured to engage with the additional electrical contact tracks 46.51, 46.52 of the longitudinal grooves 23.2, 24.2. These electrical contact tracks are mounted on the rails 31.1, 31.2 (Figures 1A, 7A), which are integral with the support 31 and which are mounted on two connection sides of the receiving housing 32. The location of the electrical contact tracks 31.11 , 31.12 (and also 31.51, 31.52) on the rails 31.1, 31.2 is complementary to the location of the electrical contact tracks 23.1, 24.1 (and also 46.51, 46.52) of the connection faces 23, 24 of the receiving device 5. The rails 31.1, 31.2 contribute to defining the receiving housing 32. They are for example located on the edge and are preferably fixed over their entire length to the support 31. The location of the electrical contact tracks 31.51, 46.51 and 31.52, 46.52 rails 31.1, 31.2 opposite, located at a distance from each other, has the advantage of limiting the risks of short-circuit if ever liquid were to flow by gravity onto one of the rails 31.1, 31.2. Shutter, coupling, withdrawal mechanism

The mixing machine 6 further includes a retention mechanism 50, a coupling mechanism 52 and a clamping mechanism 54 (Figures 10A, 10B, 10C, 10D, 10E, 10F, 11A, 11 B, 11C)

Each of these mechanisms has its own independent function. However, they can advantageously be driven simultaneously by the same auxiliary motor 40. The retention mechanism 50 has the function of preventing the removal of the receiving device 5 when the mixing is in progress.

The retention mechanism 50 is mounted movable relative to the support 31 between an insertion position and a retention position. In the insertion position, the retention mechanism 50 allows the insertion and removal of the receiving device 5 relative to the mixing machine 6. In the retention position, the retention mechanism 50 blocks the removal of the receiving device. reception 5 (and therefore would prevent its insertion).

The retention mechanism 50 comprises a movable element 50.1 between the two aforementioned positions, which extends into the receiving housing 32 in the retention position. In particular, in the retention position, the movable element 50.1 cooperates with the retention stop 9.6 to prevent a translational movement of the receiving device 5 aimed at extracting it from the mixing machine 6 (in fact, the retention stop 9.6 locks against the moving element 50.1 in the event of removal). In this regard, the movable element 50.1 and the retention stop 9.6 are provided to be located nearby in the retention position, preferably within 2mm, when the receiving device 5 is placed in the mixing machine.

In an embodiment illustrated in FIGS. 10A, 10B, 10C, the movable element 50.1 is a wheel, called the retention wheel, movable around an axis of rotation of the wheel 50.2. The wheel 50.1 has at least two different spokes, the smallest radius being configured not to extend into the receiving housing 32 in the insertion position and the largest radius being configured to extend into the receiving housing 32 in the retention position, in order to come into contact, in the event of withdrawal, against the retention stop 9.6.

The wheel 50.1 is preferably circular with a flat portion, the flat portion allowing the insertion position.

The wheel 50.1 is mounted on a shaft which extends along the axis of rotation of the wheel 50.2. This shaft comprises a pinion 51 or a pulley, connected to at least one other pinion or another pulley 51 .1.

Alternatively, the movable element 50.1 is movable in translation, for example by a rack and pinion system using the pinion 51.

The function of the coupling mechanism 52 is to establish the sealed connection between the first and second capsules 3, 4 and to ensure that the latter remain well fitted via their connection end piece 3.4, 4.4 by pressing the coupling button. 9.8 of the second protective shell 9.

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

The coupling mechanism 52 comprises a coupling element 52.1 movable between the two aforementioned positions, which extends into the receiving housing 32 in the coupling position. In particular, in the coupling position, the coupling element 52.1 cooperates with the coupling button 9.8 which moves inside the second receiving location 14. In this regard, the coupling element 52.1 and the coupling button 9.8 are located opposite, when the receiving device 5 is placed in the mixing machine 6.

In an embodiment illustrated in FIGS. 10A, 10B, 10C, the coupling element 52.1 is a wheel, known as the coupling wheel, movable around a wheel rotation axis 52.2, which is preferably confused with the wheel rotation axis 50.2. The wheel 52.1 has at least two different spokes, the smallest radius being configured not to extend in the housing of reception 32 in the insertion position and the largest radius being configured to extend into the reception housing 32 in the coupling position, in order to come into contact with the coupling button 9.8, and to press it.

The wheel 52.1 is preferably oval in shape.

The wheel 52.1 is mounted on a shaft which extends along the axis of rotation of the wheel 52.2. This shaft comprises a pinion or a pulley, connected to at least one other pinion or another pulley 51 .1. The shaft and the pinion are preferably the same as the shaft and the pinion 51. This gives a first sub-assembly integral in rotation.

Alternatively, the coupling element 52.1 is movable in translation, for example by a rack and pinion system using the pinion 51.

The coupling mechanism 52 is distinct from the actuation system 35. This results in a different position in the mixing machine 6 (for example at different heights). Similarly, the receiving device 5 includes many support points 8.3, 9.3 separate from the coupling button 9.8.

The clamping mechanism 54 has the function of blocking the outlet passage 3.5 of the first capsule 3 when the mixing process is in progress. Indeed, the pressures inside the first or second capsules 3, 4 could cause an unwanted exit of the cream. In this case, cream would spill into the mixing machine 6, which is to be avoided. It is illustrated in FIGS. 11 A, 11 B, 11C.

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

The clamping mechanism 54 comprises a clamping wheel 54.1, called the clamping wheel, which is rotatable around a clamping wheel axis 54.2.

The mixing machine 6 further comprises a fixed guide wall 54.3 (integral with the support 31, or even integral with it), against which the clamping wheel 54.1 rolls or slides, and a clamping wall against which it is clamped in the clamping position. The clamping wall is advantageously a portion of the guide wall 54.3. There are several variants: a variant in which the clamping wheel 54.1 approaches the guide wall 54.3 in the direction of the clamping position, a variant in which the distance is constant or variant in which the clamping wall has a particular concavity , to trap the clamping wheel 54.1 (this is possible thanks to a clamping wheel 54.1 movable in translation - see below).

Toothings 54.1 1 present on the clamping wheel 54.1 (in practice the wheel comprises a circular or substantially circular portion which pinches the first capsule 3 and a toothed portion, preferably under the circular portion) can cooperate in toothing 54.31 in the wall guide 54.3, so that the clamping wheel 54.1 rolls against the guide wall 54.3. In addition, thanks to the teeth 54.1 1, 54.31, the clamping wheel 54.1 has a rolling movement without sliding against the guide wall 54.3, which makes it possible to avoid slipping which would risk badly pinching the outlet passage 3.5. Finally, thanks to the teeth 54.1 1, 54.31, the distance between the clamping wheel 54.1 (except teeth, that is to say the average distance) and the guide wall 54.3 can be reduced to become almost zero under the first capsule. 3 while keeping a rolling movement against the guide wall 54.3. To allow this kinematics, the clamping wheel 54.1 is mounted, preferably mounted mobile in rotation, on an arm 54.5, which is itself mobile in rotation around an axis of rotation of arm 54.51.

The arm 54.5 is integral with a pinion (or a pulley), or with a portion of pinion 54.52, which is itself connected by various pinion or pulley to the common pinion 40.1. Consequently, the arm 54.5 is rotated by the same auxiliary motor 40.

In order to ensure a clamping in the clamping position, including when the auxiliary motor 40 is no longer under tension, the clamping wheel 54.1 is mounted movable in translation radially along the arm 54.5. Return means 54.4 disposed between the clamping wheel 54.1 and the arm 54.5 tend to separate the clamping wheel 54.1 from the arm rotation axis 54.51 and therefore to press the clamping wheel 54.1 against the guide wall 54.3. More specifically, a support intermediate, which carries the axis of rotation 54.2 of the clamping wheel 54.1 is provided. It is he who is movable in translation relative to the shaft 54.5. A sliding link with a pin 54.42 in the intermediate support which slides in a groove 54.53 of the shaft 54.5 makes it possible to guide the translation and also, advantageously, to limit the translation movement.

The return means 54.4 therefore operate in compression, insofar as by default they are not compressed (or only slightly). A coil spring, a leaf spring, or other types of springs may be suitable.

Due to the return means 54.4, the clamping wheel 54.1 can remain pressed against the guide wall 54.3 even though the distance between the guide wall 54.3 and the arm rotation axis 54.51 is variable (it can decrease towards the area where the exit passage is 3.5).

Joint training

Preferably, the retention mechanism 50, the coupling mechanism 52 and the clamping mechanism 54 are driven concomitantly, by a common drive, as described according to the exemplary embodiment below. The retention mechanism 50 is driven by a pinion 51, connected at least to another pinion 51 .1 (FIGS. 10A, 10B).

The coupling mechanism 52 is driven by a pinion, connected at least to another pinion, which are preferably the pinion 51 and the other pinion 51.1

(Figures 10A, 10B)

The clamping mechanism 54 is driven by a pinion portion 54.52. Different kinematic chains can be provided, but a common pinion 40.1 is preferably provided, which then drives the other pinion 51.1 and the pinion portion 54.52.

As illustrated in FIGS. 11 A, 11 B, 11 C, the common pinion 40.1 is located on the output shaft of the auxiliary motor 40. It directly meshes with the pinion 51 .1 which is mounted on a shaft comprising another pinion 51 .2. This pinion 51.2 in turn meshes with the pinion portion 54.52. There is thus a very simple kinematic chain, with a minimum of sprockets, and therefore a minimum of friction losses, a minimum of risk of breakage, and with little play. Thanks to this common pinion 40.1, located on the output shaft of the auxiliary motor 40, at least two of the three mechanisms 50, 52, 54 mentioned above, are simultaneously in the insertion position or in the retention, coupling position respectively , Clamping. The same auxiliary motor 40 therefore drives all three, which constitutes a major simplification of the mixing machine 6 and of its operating logic.

Visual and audible display The mixing machine 6 advantageously comprises a screen 60 and / or a loudspeaker, which make it possible to exchange information with the user (FIGS. 1A, 1B, 7).

The screen 60 is preferably tactile, to avoid having to provide physical buttons. It allows the user to indicate the start of the cycle and the time of withdrawal.

Screen 60 can also display the end of the cycle, for example with an audible warning.

Power supply and control unit

According to one embodiment of the invention, the mixing machine 6 also comprises an electric power source (not shown in the figures) configured to electrically supply the mixing machine 6, and in particular the drive motor 39 and the auxiliary motor 40. The electrical power source advantageously or even exclusively includes at least one rechargeable battery 44 (FIG. 7B). In the example illustrated, the rechargeable battery 44 is advantageously constituted by a two-cell lithium ion battery supplying a nominal output voltage of 7.4 V. As illustrated in FIG. 12, the mixing machine 6 also comprises a unit 45, comprising for example a controller such as a microcontroller or processor 45.1 such as a microprocessor, configured to control the operation of the manufacturing apparatus 2, and more particularly of the drive motor 39, of the auxiliary motor 40 , of the heating element 46, the temperature sensor and the screen 60 (for the latter a processor is preferred), as well as any sound or visual device. The control unit 45 advantageously comprises a memory 45.2, of non-volatile type, which stores the lines of instructions in the form of a program to be executed by the controller or the processor 45.1, in particular for implementing certain steps described in the method. below.

Other embodiments In a variant, the receiving device 5 is integrated into the mixing machine 6. Consequently, it suffices to insert the first or second capsule 3, 4 into the first or second receiving location 13, 14. However, a reception housing 32 is defined, which corresponds to the volume occupied by the reception device 5.

In addition, in this variant, the actuating faces 8.1, 9.1 may not be present: the actuating members 37, 38 in this case bear directly on the first or second capsules 3, 4.

Method of use

At least one method of manufacturing a composition, such as a cosmetic, using the manufacturing apparatus 2 will now be described. This manufacturing process is broken down into several sub-processes (called “processes” for reasons of clarity), one or more variants of which will be described. We distinguish in particular a preliminary process Ep, an initialization process Ei, a mixing process Em, then a removal process Er.

In particular, these methods (or their variants) are advantageously implemented using the various embodiments of the manufacturing apparatus 2 described above. Preferably, most of the steps of the methods Ei, Em and Er are stored in the memory 45.2, of non-volatile type, in the form of instructions in lines of code able to be executed by the processor 45.1.

A preliminary process Ep comprises a step Ep1 preliminary to any use of the manufacturing apparatus 2 which consists either in connecting it to the mains either to recharge the battery 44. In addition, this preliminary step Ep1 can be preceded or followed by a step Ep2 for positioning the manufacturing device 2 on a flat support, possibly with a step for energizing.

Then, an Ei initialization process is implemented. In a step Ei 1 (“reception step”), the processor of the manufacturing machine 2 receives a start instruction. This start instruction is typically generated by a user action (contact with the touch screen 60, press button, switch, etc.).

Following this step Ei1, in a step Ei2 (“verification step”), the method ensures that the actuation system 35 is in the neutral position, allowing the insertion of the receiving device 5 or the insertion of the first and second capsules 3, 4. Typically, it is necessary to ensure that the receiving housing 32 (for the insertion of the receiving device 5) or the first or second receiving location 13, 14 (for the insertion of the first or second capsules 3, 4 when there is no receiving device 5) are not obstructed by the actuating system 35. During this step Ei2, it should also be checked that the tightening mechanism 54, the mechanism coupling 52, and the retention mechanism 50 are deactivated, that is to say in their respective insertion position.

Following this step Ei2, it is possible to manually insert the reception device 5 containing the first or second capsules 3, 4, or even directly insert the first or second capsules 3, 4, into the reception housing 32.

Finally, in a next step Ei3 (“closing step”), at least one of: the clamping mechanism 54, the coupling mechanism 52, the retention mechanism 50 are activated, that is to say that they're moving. This step Ei3 consists for example of a setpoint by the processor intended for the auxiliary motor 40 to trigger it, so that it drives the three aforementioned mechanisms in the case where they are all connected to the common pinion (or pulley) 40.1. The auxiliary motor 40 moves from a first position to a second position, so that the clamping mechanism 52, the coupling mechanism 54 and the retention mechanism 50 pass from their respective insertion position to their positions. respective tightening, coupling and retention. Preferably, the auxiliary motor 40 maintains the second position at the end of step Ei3, even if it is no longer supplied.

The steps Ei1, Ei2 and Ei3 are executed in particular by the processor 45.1.

At the end of this initialization process Ei, the mixing machine 6 is ready to start work on the first and second capsules 3, 4: this is the object of the mixing processes Em and of removal Er.

The mixing process Em comprises a first step Em1 of the preparation phase (“primary step of setting in motion of the actuation system”), during which the bond weld of the capsule positioned furthest from the heating element 46 (the second capsule 4 in the figures), and this capsule is compressed so that its content is sent in part to the capsule closest to the heating element 46. According to the embodiment shown, the second member actuator 38 is set in motion to break the bonding weld in the second capsule 4 (which includes for example the fatty phase formulation). In this way, part of the content of the second capsule 4 is sent to the side of the first capsule 3, in particular in the connection passage 3.3 (because the connection weld of the first capsule 3 is not yet broken). The second actuating member 38 is preferably set in motion according to its actuating stroke C38. For reasons of simplification of design, there is not necessarily a partial stroke sensor for the second actuating member 38.

In a step Em2 of the preparation phase (“secondary step of setting the actuating system in motion” or “prestressing step”), the first actuating member 37 is set in motion according to a partial stroke strictly less than its stroke actuator C37 and keeps its position, in order to exert a prestress on the first capsule 3 (which includes for example the aqueous phase formulation) so that the flat face 3.7 is pressed against the diffusion plate 46.2. This prestressing promotes the heat exchange between the diffusion plate 46.2 and the first capsule 3 during a subsequent step Em3 (“heating step”). It should be noted that this pressurization of the first capsule 3 against the diffusion plate 46.2, thanks to the setting in motion of the first actuating member 37 over a partial stroke, takes place without causing the rupture of the connecting weld in the first capsule 3 (which would cause the formulation to be sent from the first capsule 3 to the second capsule 4).

In the preparation phase step Em3 (“heating step”), the heating element 46 is activated to generate heat intended for the first capsule 3. As the heating element 46 is positioned on the side with the flat face 3.7 of the first capsule 3, and that the prestressing step has allowed good thermal contact between the diffusion plate 46.2 and the first capsule 3, the heat supplied by the heating element 46 is well distributed over the contents of the first capsule 3. The step Em3 is therefore activated in the absence of any movement of the actuating members 37, 38.

During the step Em3 of the preparation phase, the temperature of the heating element 46 reaches a target temperature Te of between 80 ° C. and 90 ° C. The objective of this target temperature Te is that the content of the first capsule 3 reaches a target temperature Te ’also between 80 ° C and 90 ° C and preferably around 85 ° C. Indeed, it has been found that the temperature of the content of the first capsule 3 during this heating step Em3 corresponds substantially to the target temperature Te of the heating element 46, with however a slight time difference.

Then, in a step Em3 'of kneading phase ("mixing step"), the heating element 46 is deactivated and then the first actuating member 37 is set in motion according to its nominal stroke to break the bonding weld in the first capsule 3. Cutting off the electrical supply to the heating element 46 prior to activation of the first actuating member 37 makes it possible to have all of the power supplied by the electrical power source available to supply the drive motor 39. Such a characteristic is particularly advantageous in the case where the mixing machine 6 is supplied by a transformer power supply or a low power battery 44. Indeed, it makes it possible to avoid that the power supplied to the drive motor 39 is insufficient to allow the rupture of the bonding weld of the first capsule 3 (which would then lead to blockage of the device), this step of rupture of the bonding weld requiring significant motor torque. When the first actuating member 37 reaches its end of actuating travel C37, the content of the first capsule 3 is sent into the second capsule 4 and the two formulations can then circulate freely from a first or second capsule 3, 4 to the other second or first capsule 4, 3 passing through the connection parts 3.2, 4.2 with each return movement of the actuating system 35, the connection welds originally present in each of the first and second capsules 3, 4 having been broken.

Thereafter, steps Em4, Em5, Em6 are successive kneading steps, with or without heating (we speak of kneading phase).

The step Em4 of the kneading phase (“kneading step without heating”) consists in setting in motion the actuating members 37, 38 in a back-and-forth without activation of the heating element 46, that is to say ie without heating. During this step, the first and second capsules 3, 4 are deformed at least once each. According to one embodiment, the step Em4 lasts at least 1, 4 s and preferably between 2s and 4s. Such a kneading step without heating makes it possible to start the drive motor 39 at a constant speed while benefiting from all the power of the electric power source.

Steps Em1, Em2 and Em3, Em3 ', Em4 alternate setting in motion of the actuation system 35 and heating with the heating element 46. This translates concretely into a dedicated electrical supply either to the actuation system 35 or to heating element 46. This exclusive alternation makes it possible to preserve the battery 44 by distributing the moments of high power. Indeed, the engagement of the setting in motion generates a significant resistant torque which imposes a significant engine torque and the rise in temperature also requires significant power: the battery 44 is therefore in high demand. This work-study solution also makes it possible to reduce the size of components, which is a design constraint when creating a mixing machine, portable and on batteries.

On the other hand, once the temperature is close to the target temperature Te ′ and once the actuation system 35 is already in motion, the stresses on the battery 44 are reduced and allow power to be supplied to the heating element 46 and to the system. actuation 35 in parallel: this is the object of step Em5.

During the step Em5 of the kneading phase (“kneading step with heating”), the actuation system 35 remains activated and the heating element 46 is reactivated in order to maintain the mixture of the formulations at a temperature, which is preferably the target temperature Te '. Therefore, the heating element is kept at the target temperature Te. This step Em5 lasts for example between 5s and 30s, preferably between 7s and 15s. Although the battery 44 is less stressed than for an engagement or a rise in temperature, it can tend to discharge quickly in this phase which is therefore limited in duration.

However, this step Em5 is long enough for the first and second capsules 3, 4 to be deformed several times each and for the emulsion obtained by mixing the formulations to be satisfactory.

Between step Em4 and Em5, the actuation system 35 was not interrupted.

Subsequently, the step Em6 of the kneading phase (“cooling step with kneading”) is implemented. Alternatively, this step is carried out without kneading, but it is preferable to keep the actuation system 35 activated to improve or maintain the homogenization of the formulations. During step Em6, the temperature of the cream decreases to a shrinkage temperature Tr 'of between 35 ° C and 48 ° C, preferably 38 ° C and 42 ° C. In the case of the embodiment presented, the withdrawal temperature Tr 'of the cream corresponds to a withdrawal temperature Tr of the heating element 46 between 55 ° C and 60 ° C. This temperature difference between the content 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 kneading, the composition is not has only part of the time in the first capsule 3 and therefore facing the diffusion plate 46.2 at which the temperature measurement is carried out.

The simplest technique for cooling is to stop supplying the heater 46 and allow the cream to cool with air at room temperature. Consequently, the duration of step Em6 effectively depends on the ambient temperature. In this regard, a temperature sensor is advantageously positioned in the mixing machine 6, and more precisely in the receiving device 5. In order to limit the number of temperature sensors, it is the same sensor which measures the temperature of the heating element 46.

As in the illustrated embodiment, the temperature sensor measures the temperature of the heating element 46, the same sensor is used again: this means that the end of step Em6 is determined by the temperature measured by said sensor, c ' that is to say the withdrawal temperature Tr 'between 55 ° C and 60 ° C.

Once the withdrawal temperature has been reached, the actuation system 35 is stopped.

The Em6 cooling step generally lasts at least 20s and preferably 40s.

In an alternative embodiment, step Em6 could also advantageously include a minimum mixing time, for example of the order of 40 s, making it possible to guarantee a good emulsion, then an additional mixing time which only occurs when the withdrawal temperature Tr 'has not yet been reached. In other words, it is still kneaded for a certain period of time even if the temperature is below the withdrawal temperature Tr ’.

It should be noted that the mixing machine 6 could, according to an embodiment not illustrated, include a cooling system for actively cooling the cream and accelerating the process. It could for example be provided with a cooling system provided with a small fan in addition or not with a cooling element, the fan forcing air circulation in the mixing machine 6, and therefore convection cooling. forced. Once the mixing process Em has ended, the withdrawal process Er can be started. This Er removal process will now be described. As the previous steps take some time (more than a minute in general), it is likely that the user does not stay next to the mixing machine 6 but that he goes about his usual activities (breakfast, radio, television, bread and butter, dressing, ironing, etc.). Thus, it is important that the mixing machine 6 can hold the cream in a ready-to-use state for a fixed period.

To this end, in a step Er1 (“transfer step for storage”), the actuation system 35 is activated once to transfer the cream into the capsule which is located on the side of the heating element 46 (this is i.e. the first capsule 3 here). This step is optional if step Em6 has already stopped in the correct configuration.

In a step Er2 (“prestressing holding step”), the actuation system 35 is returned to the prestressed position, where the first actuating member 37 exerts a prestress on the first capsule 3 to press it against the diffusion plate 46.2 , then, in a step Er3 (“temperature maintenance step”), the heating element 46 is reactivated to keep the cream at the withdrawal temperature Tr '. The prestressing step Er2 allows better heat conduction, like the step Em2. Preferably, a mixing or movement of the actuation system 35 is implemented periodically during step Er3 to guarantee a good emulsion, the latter possibly being partially damaged by the presence of hot spots on the diffusion plate 46.2.

In an alternative embodiment, the removal process may include, in place of the step step Er2, a step Er2 '(“step of maintaining in neutral position”) in which the actuation system 35 is activated to be placed in the neutral position, that is to say without constraining the first or second capsules 3, 4, and in particular without constraining the first capsule 3 against the heating element 46. Surprisingly, such a variant makes it possible to preserve a better emulsion and avoid having to use periodic mixing during the warming phase.

Stage Er3 is carried out during a predetermined waiting time. This duration is less than 15 min, so as not to supply the heating element 46 for too long, but more than 1 min, to allow flexibility in the morning time management for the user, and preferably of the order of 5 min.

In other words, this means that the user has between 1 min and 15 min, and preferably of the order of 5 min (depending on factory settings or user settings) after the movement of the system d actuation 35 to collect the cream at the right temperature.

As soon as the user is ready to use the cream, he touches the touch screen or presses a button, which triggers a step Er4 (“step for receiving withdrawal instructions”), during which the mixing machine 6 receives a withdrawal instruction.

Then, in a step Er5 ("step to put in neutral position"), the actuation system 35 is activated to be put in neutral position.

In the case where the actuating system 35 was previously prestressed at the first actuating member 37 the latter must complete its movement, which displaces the formulation in the second capsule 4, then the actuating system 35 s' stops in neutral position which corresponds to a position suitable for extracting the receiving device 5. This position also corresponds to a starting position suitable for carrying out a next manufacturing cycle implementing the method described above. Indeed, the second actuator 38 is then ready to compress the second capsule 4 during step Em1 as soon as the drive motor 39 is started.

In the case of the alternative embodiment where the actuation system 35 was put in neutral position during step Er2 'for maintaining the temperature of step Er3, it may be necessary for the actuation system 35 have to go back and forth to position themselves in the neutral position suitable for carrying out a next manufacturing cycle implementing the process previously described, that is to say with the second actuating member 38 ready to compress the second capsule 4 during step Em1.

During this round trip of the actuating system 35, the cream present in the first capsule 3 is partially sent into the second capsule.

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

Thereafter, the user grabs the receiving device 5 and removes it from its receiving housing 32. Then he presses on the actuating faces 8.1, 9.1 to rotate the pallets in order to expel the cream present in the first and second capsule 3, 4 through the outlet passage 3.5 of the first capsule 3. Finally, it suffices to remove the first or second capsules 3, 4 from the receiving device 5 so that the latter is again ready for use. Indeed, no part of the mixing machine 6 (manufacturing device 2 or receiving device) has been in contact with the formulations.

The different stages of implementation of the method described above, which can for example be implemented successively, are therefore the following:

Ei1: step for receiving a departure instruction (implemented by the mixing machine and more precisely by the processor),

Ei2: positioning step of the actuation system (implemented by the mixing machine and more precisely by the processor which controls the drive motor),

Ei3: closing step, preferably in parallel, of the tightening, retention and coupling mechanisms (implemented by the mixing machine and more precisely by the processor which controls the auxiliary motor), Em1: primary setting step movement of the actuation system to break the bonding weld of one of the capsules (implemented by the mixing machine and more precisely by the processor which controls the drive motor), Em2: secondary step of setting in motion the actuation system to exert a prestress on the other capsule (implemented by the mixing machine and more precisely by the processor which controls the drive motor),

Em3: heating step of the prestressed capsule (implemented by the mixing machine and more precisely by the processor which controls the heating element),

Em3 ': mixing step by setting in motion the actuation system to break the bonding weld of the other capsule and allow free circulation of the formulations from one capsule to the other (implemented by the mixing machine and more precisely by the processor which controls the drive motor),

Em4: mixing step without heating to start the motor at constant speed (implemented by the mixing machine and more precisely by the processor which controls the drive motor),

Em5: mixing step with heating to produce the emulsion (implemented by the mixing machine and more precisely by the processor which controls the drive motor and the heating element),

Em6: cooling step with mixing and without heating (cooling) up to the withdrawal temperature (implemented by the mixing machine including the processor which controls the drive motor),

Er1: optional transfer step for storage with setting in motion of the actuation system (implemented by the mixing machine and more precisely by the processor which controls the drive motor),

Er2: step of placing the actuation system in pre-stressed position (implemented by the mixing machine and more precisely by the processor),

Er2 ’: step (alternative to step Er2) setting the actuation system in neutral position (implemented by the mixing machine and more precisely by the processor which controls the drive motor)

Er3: temperature maintenance step (implemented by the mixing machine and more precisely by the processor),

Er4: step for receiving a withdrawal instruction (implemented by the mixing machine and more precisely by the processor), Er5: step of putting the actuation system in neutral position (implemented by the mixing machine and more precisely by the processor which controls the drive motor)

Er6: unlocking step (implemented by the mixing machine and more precisely by the processor which controls the auxiliary motor).
