Description

Technical Field

[0001] This invention relates to a manufacturing apparatus for producing compositions, particularly cosmetic compositions, or more precisely, to a manufacturing apparatus for preparing compositions by mixing two formulations. Background Technology

[0002] Document FR3026622 discloses a manufacturing apparatus for producing compositions, more specifically cosmetic products, the apparatus comprising:

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

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

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

[0006] Mixers include, in particular:

[0007] A first pressing element includes a first pressing surface configured to apply pressure to a deformable first compartment of a first capsule, the pressure being perpendicular to the direction of movement of the first pressing element.

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

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

[0010] This manufacturing equipment allows end consumers to create personalized beauty products using different capsules.

[0011] However, the structure of the manufacturing equipment described in document FR3026622 requires a large-sized drive motor to transmit pressure to the deformable first and second compartments, which is suitable for ensuring that the contents move from the first compartment toward the second compartment and vice versa, especially when the deformable first and second compartments or the connecting channels connected to the deformable first and second compartments are closed by weakly connected areas.

[0012] The use of large-sized drive motors significantly increases the manufacturing cost, size, and weight of the equipment.

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

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

[0015] Therefore, the technical problem upon which this invention is based is to provide an apparatus for manufacturing compositions that is simple, compact, and easy to use, while having a simple and cost-effective structure.

[0016] In particular, certain designs in the form of mixers that can house storage devices for integrated capsules raise additional issues of accessibility and function, especially regarding the displacement of capsules, particularly in formulations or compositions between capsules. Furthermore, the storage device should obviously be as compact as possible.

[0017] In this regard, the present invention provides a storage device for forming a manufacturing apparatus when the storage device is inserted into a mixer, the storage device comprising:

[0022] At least one support element is a tray that can rotate about a hinge, the movable tray being configured to enter one of the first and second storage positions.

[0023] In one embodiment, the storage device includes an insertion surface and an opposing exit surface, through which the capsule can be inserted into its respective storage position, and the hinge is located on the side of the exit surface.

[0024] In one embodiment, the hinge is located at the end of the storage position.

[0025] In one embodiment, the first or second support element includes a flat inner surface.

[0026] In one embodiment, the first or second support element is movable between an unfolded position and a folded position, wherein the retracted position can receive the insertion of the capsule, and the support element is configured to compress the capsule positioned at the retracted position to expel the contents of the capsule.

[0027] In one embodiment, the storage device includes a first support element and a second support element, both of which are rotatable about a hinge and configured to enter their respective storage positions.

[0028] In one embodiment, the two hinges are located on the same side.

[0029] In one implementation method

[0030] - The first actuating surface includes a first support portion, the first support portion includes a first support element, and the first support element is rotatable relative to the first support portion;

[0031] - The second actuating surface includes a second housing and a second support portion, the second support portion including a second support element, the second support element being rotatable relative to the second support portion.

[0032] In one embodiment, the storage device includes:

[0033] - A first housing, the first housing facing the first support element including an opening or a flexible material; and

[0034] - A second housing, the second housing facing the second support element including an opening or a flexible material.

[0035] The present invention also relates to an apparatus for manufacturing cosmetics, comprising a mixer including a storage device as described above.

[0036] The present invention also relates to an apparatus for manufacturing cosmetics, comprising a mixer including a support member defining a receiving portion, wherein the receiving portion removably houses the receiving device as described above.

[0037] The present invention also relates to a mixer comprising:

[0038] - A support member defining a receiving portion, the receiving portion including a first receiving position and a second receiving position, the first receiving position being configured to receive a deformable first capsule, the second receiving position being configured to receive a deformable second capsule, the first capsule and the second capsule being fluidly connected to each other and respectively containing a first formulation and a second formulation;

[0039] - An actuation system, which is movable relative to the support member within the receiving portion.

[0068] Figure 1A and Figure 1B A manufacturing apparatus 2 according to a first embodiment of the present invention is shown. This apparatus is configured to manufacture a composition, which may be, for example, a beauty product, hair care product, pharmaceutical product, antibacterial product, skincare product, cleaning product, or agricultural product. When the composition to be manufactured is a beauty product, the beauty product may be, for example, a homogeneous emulsion, a homogeneous solution, or a mixture of multiple soluble phases.

[0069] Manufacturing device 2 is intended for primary personal use and is designed for small sizes: Manufacturing device 2 allows for the manufacture of a single, usable piece. Therefore, the dimensions of this manufacturing device must meet volume restrictions in applications such as bathrooms, beauty salons, and luggage (for transport). Thus, manufacturing device 2 must not have a size greater than 40cm.

[0070] Manufacturing equipment 2 includes a receiving mechanism and a mixer 6. The receiving mechanism is configured to receive first and second capsules 3, 4, which are also referred to as tablets or packaging units. The first and second capsules respectively contain a predetermined amount of a first formulation and a predetermined amount of a second formulation. The mixer is configured to mix the first and second formulations contained in the first and second capsules 3, 4 contained in manufacturing equipment 2 to obtain a beauty product.

[0071] The mixer 6 includes a receiving section that is part of a storage mechanism and is configured to receive the first and second capsules 3,4 directly or via a specific storage device 5.

[0072] In preferred and especially in the appendix Figure 1A In all embodiments visible in the accompanying drawings 1B, 7A, 8A, 8B, and 8C, the mixer 6 includes a receiving portion 32 capable of removably accommodating the storage device 5. In this case, the receiving portion 32 has a shape that is substantially complementary to the shape of the storage device 5.

[0073] The mixer 6 also includes an actuation system 35 configured to apply force to the first and second capsules 3,4, and, if necessary, via the receiving device 5, to allow mixing and stirring of the composition to be manufactured.

[0074] The receiving device 5 is also referred to as a shuttle (because it serves as a carrier for the first and second capsules 3, 4) and preferably has a relatively symmetrical shape, such as a parallel rectangle or an elliptical / oval shape. A longitudinal direction X can be defined for the receiving device, which corresponds to a direction along which the receiving device is inserted into the receiving portion 32. Therefore, when the receiving device 5 is inserted into the mixer 6, the longitudinal direction X coincides with the insertion direction.

[0075] Advantageously, the mixer 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 formulation coming into contact with the manufacturing equipment 2.

[0076] As noted above, some of the embodiments present herein can be used in manufacturing equipment 2 without the receiving device 5, i.e., in which the first and second capsules 3,4 can be directly positioned in the mixer.

[0077] Advantageously, the first formulation is the first phase of the cosmetic product to be manufactured, such as the oil phase of the cosmetic product, while the second formulation is the second phase of the cosmetic product, such as the aqueous phase of the cosmetic product. For example, the oil phase may constitute the matrix of the cosmetic product to be manufactured, and the aqueous phase may include active ingredients and thus constitute the active complex of the cosmetic product to be manufactured.

[0078] capsule

[0079] The two capsules can be used in the given manufacturing apparatus 2, as described in detail in the document filed with application number FR1755744, and the description of the capsules is contained herein.

[0080] Capsules are therefore not the subject of this invention. For the purposes of the following description, the following key points will be revisited.

[0081] More specifically, such as Figure 2A As shown in 2B, 3A, 3B, 4A, and 4B, the first and second capsules 3 and 4 are different from each other and are configured to be fluidly connected to each other. Furthermore, each of the first and second capsules 3 and 4 is advantageously disposable.

[0082] The first capsule 3 includes a first deformable compartment 3.1 having a convex shape, a first connecting portion 3.2, and a first connecting channel 3.3. The first deformable compartment contains a first formulation, and the first connecting channel is configured to fluidly connect the first deformable compartment 3.1 and the first connecting portion 3.2. Advantageously, the first connecting channel 3.3 is formed by a first connecting conduit. The first connecting portion 3.2 more specifically includes a female connector 3.4, for example, in a cylindrical shape, which is fluidly connected to the first connecting channel 3.3. The first capsule 3 includes a flat surface 3.7 through which the first connecting portion 3.2 passes.

[0083] The first capsule 3 also includes an output channel 3.5, such as an output pipe, which is fluidly connected to the first connecting channel 3.3 and is equipped with an output port 3.6. Advantageously, the output channel 3.5 extends in an extension of the first connecting channel 3.3 and is substantially parallel to the first connecting channel 3.3. In this case, the output channel 3.5 can be installed on either the first capsule 3 or the second capsule 4 without distinction. In fact, the output channel 3.5 is only required to operate when the manufacturing equipment 2 is used.

[0084] The second capsule 4 includes a second deformable compartment 4.1 having a convex shape, a second connecting portion 4.2, and a second connecting channel 4.3. The second deformable compartment contains a second formulation. The second connecting portion 4.2 is configured to connect to a first connecting portion 3.2, and the second connecting channel is configured to fluidly connect the second deformable compartment 4.1 and the second connecting portion 4.2. Advantageously, the second connecting channel 4.3 is formed by a second connecting conduit, and the second connecting portion 4.2 extends substantially perpendicularly to the second connecting channel 4.3. More specifically, the second connecting portion 4.2 includes, for example, a cylindrical male connector 4.4, which is fluidly connected to the second connecting channel 4.3 and configured to sealably receive the female connector 3.4. The second capsule 4 includes a flat surface 4.7 through which the second connecting portion 4.2 passes.

[0085] The first and second capsules 3,4, and more specifically the first and second deformable compartments 3.1,4.1, each independently ensure the sealing of the first and second capsules 3,4 with a bonding solder seal, which is brittle as long as a pressure threshold is reached. These pressure thresholds can be reached in the mixer 6. Furthermore, these bonding solders are described in detail in the document filed with application number FR1755744.

[0086] Each of the first and second capsules 3, 4 is configured to contain a whole or near-whole mixture of a predetermined amount of a first formulation and a predetermined amount of a second formulation. For this purpose, the deformable compartment is flexible and has a buffer area. Furthermore, this is precisely described in the description of the document filed with application number FR1755744.

[0087] Storage device

[0088] More specifically, such as Figure 2A As shown in 2B, 3A, 3B, 4A, 4B and 5, the storage device 5 is capable of occupying an open position and a closed position. In the open position, the first and second capsules 3,4 can be inserted into the storage device 5, and in the closed position, the storage device 5 can hold the first and second capsules 3,4 in place.

[0089] The storage device 5 more specifically adopts the storage box 7 ( Figure 2A In the form of 2B), the storage box is configured to at least partially store and accommodate the first and second capsules 3,4. The storage device 5 specifically includes a first protective shell 8 and a second protective shell 9, which are positioned around a hinge axis 10 (or hinge) in a first position (see...). Figure 2A , 2B, 5) and the second position ( Figure 4AThe storage device 5 is hinged to each other between the two components 4B, with the first position corresponding to the open position and the second position corresponding to the closed position. The storage device 5 also includes a first support portion 11 and a second support portion 12 disposed within the storage box 7. The first and second support portions 11 and 12 respectively include a first storage position 13 and a second storage position 14, the first storage position being configured to store the first capsule 3 and the second storage position being configured to store the second capsule 4. The first and second protective shells 8 and 9 each include openings 8.2 and 9.2 for allowing access to the first or second storage position 13 or 14. These openings 8.2 and 9.2 define an insertion surface of the storage device 5. The storage device 5 includes a removal surface opposite the insertion surface.

[0090] Advantageously, the first support portion 11 includes a storage pad 15 configured to receive the peripheral portion of the capsule 3, and the second support portion 12 also includes a storage pad 15 configured to receive the peripheral portion of the second capsule 4. These storage pads 15 partially define the first and second storage locations 13, 14.

[0091] The first support portion 11 includes a first mounting surface 11.1, which is configured to guide (have contact with) and receive the flat surface 3.7 of the first capsule 3. The first mounting surface 11.1 thus partially defines the first receiving position 13.

[0092] In the same manner, the second support 12 includes a second mounting surface 12.1, which is configured to guide (have contact with) and receive the flat surface 4.7 of the second capsule. The second mounting surface 12.1 thus partially defines the second receiving position 14.

[0093] When the first and second capsules 3, 4 are inserted, their respective flat surfaces 3.7, 4.7 turn toward each other and have two mounting surfaces 11.1, 12.1 between the flat surfaces.

[0094] To allow passage of the first and second connecting portions 3.2, 4.2 of the first and second capsules 3, 4, the first and second mounting surfaces 11.1, 12.1 each include a passage opening 11.2, 12.2, which has a slit shape and is located along the insertion axis X. Figure 1A It opens outwards.

[0095] The storage device 5 also includes a partition wall 22, which defines a partition surface. Figure 3A(3B). The partition wall 22 is located between the first and second storage positions 13, 14. The partition wall is also integrally connected to the first support portion 11. The partition wall 22 includes an opening 22.2 to allow the first and second connecting portions 3.2, 4.2 to be positioned in the storage device. The opening 22.2 has the form of a through cut in thickness and is open to the outside.

[0096] Openings 11.2, 22.2, and 12.2 thus form spaces for receiving the connecting joints 3.4 and 4.4 of the first and second capsules 3 and 4.

[0097] In addition, a first actuating surface 8.1 and a second actuating surface 9.1 are defined. The first actuating surface includes a first shell 8 and a first support portion 11, and the second actuating surface includes a second shell 9 and a second support portion 12.

[0098] Each actuating surface 8.1, 9.1 participates in the transmission of the force received by the receiving device 5 toward the first and second capsules 3, 4. This will be explained in detail below.

[0099] Hinged

[0100] According to Figure 2A In the embodiments visible in 2B, 3A, 3B, and 5, the first and second housings 8 and 9 surround the hinge axis 10 and are in the retracted position (see...). Figure 2A 2B, 3A, 3B) and connection locations (see Figure 4A The first and second capsules 8 and 9 are hinged to each other in the following positions: 1) the first and second shells 8 and 9 are far apart from each other, and 2) the first and second capsules 3 and 4 can be stored in the first and second storage positions 13 and 14 respectively. In the following connection positions, the first and second shells 8 and 9 are close to each other, and 2) the first and second capsules 3 and 4 are pre-connected to each other. Pre-connection means that the male connector 4.4 of the second capsule 4 is partially inserted into the female connector 3.4 of the first capsule 3, without establishing a sealed connection between the first and second capsules 3 and 4.

[0101] When the first and second shells 8, 9 are in the retracted position, they may have an inclination angle of greater than or equal to 7°, and for example, about 7°. When the first and second shells 8, 9 are in the connected position, they are generally parallel to each other. More precisely, there are two main integral parts that are hinged to each other only: on one side is the first shell 8, the first support 11, the partition wall 22 and the second support 12; on the other side is the second shell 9.

[0102] Advantageously, the first and second housings 8, 9 (or actuating surfaces 8.1, 9.1) are configured such that when the storage device 5 is moved to the closed position, the first connecting portion 3.2 is inserted into the second connecting portion 4.2. In fact, when the first and second housings 8, 9 are in the closed position, the connecting portions 3.2, 4.2 are partially nested within each other.

[0103] The first and second supports 11, 12 are more specifically configured such that when the first and second shells 8, 9 are in the connected position, the first and second capsules 3, 4 extend substantially parallel to each other. For example... Figure 4A As shown in 4B, when the first capsule is housed in the housing device 5 and the housing device 5 is in the closed position, the first capsule 3 is configured to extend partially outside the housing device 5. Advantageously, when the first capsule 3 is housed in the housing device 5 and the housing device 5 is in the closed position, the output port 3.6 is configured to extend outside the housing device 5.

[0104] heating element

[0105] Manufacturing equipment 2 includes Figure 3A Heating element 46 is visible in 3B. In the embodiment shown in the figure, heating element 46 is part of the housing 5. However, in the absence of the housing 5, the heating element can be integrated with the mixer.

[0106] Heating element 46 is fixed to partition wall 22. In the design, heating element 46 has been selected on the side of the first support 11, which means that heating element 46 is installed on the side of partition wall 22 on the side of the first support 11.

[0107] The heating element 46 preferably includes one or more heating resistors 46.1 and a diffuser plate 46.2. The heating element 46 therefore has a flat shape for better heat dissipation, and if possible, the heating element has a diameter of at least 500 mm. 2 And preferably about 800mm 2 The area.

[0108] However, since the first support portion 11 is located between the first capsule 3 and the heating element 46, a communication opening 46.3 is provided in the first support portion 11, which directly connects the flat surface 3.7 of the first capsule 3 with the heating element 46 (i.e., separated only by air).

[0109] Electrical contact rails of heating element

[0110] The heating element 46 needs to be powered. Preferably, the storage device 5 does not include its own battery and should be powered when the storage device is inserted into the receiving part 32.

[0111] Therefore, an electrical connection is provided between the storage device 5 and the mixer 6.

[0112] The storage device 5 includes an insertion surface and a removal surface. Openings 8.2 and 9.2 are located on the insertion surface, which is the surface that first enters the receiving portion 32. The removal surface is opposite to the insertion surface and is visible when the storage device 5 is inserted into the receiving portion 32. The storage device 5 also includes opposing first actuation surfaces 8.1 and 9.1.

[0113] Finally, the storage device 5 includes a first connecting surface 23 and a second connecting surface 24 that are preferably opposite each other. Figure 2A In the embodiments shown in 2B, 3A, 3B, 4A, and 4B, the connecting surfaces 23 and 24 correspond to the sides of the heating element 46 and are therefore different from the first and second actuation surfaces 8.1, 9.1 and the insertion / removal surfaces.

[0114] The connecting surfaces 23 and 24 extend between the actuating surfaces 8.1 and 9.1 of the storage device 5. Preferably, the connecting surfaces 23 and 24 connect the actuating surfaces 8.1 and 9.1 of the storage device 5, that is, they are adjacent to each other.

[0115] The typical shape of the storage device 5 is chosen such that the connecting surfaces 23 and 24 are spaced further apart than the actuating surfaces 8.1 and 9.1 (and more apart than the insertion / removal surfaces). On the other hand, if a smallest parallelepiped in which the storage device 5 is inserted is used, the surfaces contacting the connecting surfaces 23 and 24 are further apart than the surfaces contacting the actuating surfaces 8.1 and 9.1 and closer together than the surfaces contacting the insertion / removal surfaces. This is due to the fact that the width of the storage device is greater than its thickness (and, moreover, its height is greater than its width).

[0116] The first connecting surface 23 includes a first electrical contact rail 23.1 for supplying power to the heating element 46, and the second connecting surface 24 includes a second electrical contact rail 24.1 for supplying power to the heating element 46. Figure 2A 3A, 3B, 4A, 4B). Electrical contact rails 23.1, 24.1 are therefore located outside the housing 5 so as to contact the complementary rails ( Figure 2A , 4A, 4B).

[0117] This configuration offers several advantages: First, it ensures a simple and efficient electrical connection. It also avoids the risk of short circuits. In fact, once liquid flows in the container 32 (e.g., water in a shower or sink, or a simply ruptured capsule), it is impossible for both electrical contact tracks 23.1, 24.1 to simultaneously contact the same amount of liquid.

[0118] The first connecting surface 23 includes a portion of the first and second shells 8 and 9, the first support portion 11, and the partition wall 22.

[0119] Specifically, the first connecting surface 23 includes a longitudinal groove 23.2, which has a bottom 23.21 and two sidewalls 23.22, 23.23. The first electrical contact track 23.1 is preferably positioned on the sidewall 23.22 of the longitudinal groove 23.2. Figure 3A In the embodiment shown in 3B, the bottom 23.21 and the sidewall 23.23 are achieved by a portion of the first support 11. A suitable cutout 8.5 is thus provided in the first housing 8 to provide space for the longitudinal groove 23.2. The opposing sidewall 23.22 is achieved by a portion of the partition wall 22. The first electrical contact track 23.1 is thus positioned on this sidewall 23.22 (because the heating element 46 is mounted on the partition wall).

[0120] Similarly, a similar longitudinal groove 24.2 is provided on the second connecting surface 24. This longitudinal groove has a cutout 9.5 in the second shell 9 and has a bottom 24.21 and two opposing sidewalls 24.22, 24.23. Due to the non-fixed center of the groove, the cutout 9.5 in the second shell 9 is significantly less prominent than the cutout 8.5 in the first shell 8.

[0121] The grooves 23.2 and 24.2 are configured to engage with respective complementary guides 31.1 and 31.2 (sliding connection) disposed in the receiving portion 32 and on the (preferably opposite) connecting sides. Figure 1A (7A). Therefore, the grooves 23.2 and 24.2 form a cutting portion that extends over the entire height of the portion of the receiving device 5 where the groove is located, extending at least to the insertion height. The complementary guides 31.1 and 31.2 help to define the receiving portion 32 and position it on the opposite edges.

[0122] In particular Figure 4A In the embodiment visible in 4B, the electrical contact tracks 23.1 and 24.1 are not located on the same horizontal plane, but are staggered.

[0123] The electrical contact rails 23.1 and 24.1 can take various forms, such as electric needles or metal sheets (as shown). Preferably, the electrical contact rails 23.1 and 24.1 can be slightly deformed to ensure sustained contact when the receiving device 5 is placed in the receiving portion 32.

[0124] Therefore, it is noted that the longitudinal grooves 23.2 and 24.2 are not centered relative to the first and second actuating surfaces 8.1 and 9.1 (see especially). Figure 2A (4A, 4B). In terms of design, this is mainly due to the grooves formed in the first support 11 and the first protective shell 8.

[0125] The benefit of this asymmetry lies in its positioning function. In fact, it is impossible to place the storage device 5 in the wrong direction (rotated 180° around the longitudinal axis X) because the grooves 23.2 and 24.2 cannot be inserted into the guide rails 31.1 and 31.2, and the second shell 9 abuts against the guide rails 31.1 and 31.2.

[0126] To provide a positioning effect for vertical rotation (i.e., attempting to insert the take-out surface first instead of the insertion surface), the longitudinal grooves 23.2, 24.2 do not extend over the entire height of the portion of the first or second housing 8, 9 in which they are located. Therefore, without the need for special parts, the stopping effect is simply achieved through the portion of the first or second housing 8, 9 that is not penetrated by the cutting effect. On the other hand, when the receiving device 5 is in the wrong orientation, the first or second housing 8, 9 prevents the grooves 23.2, 24.2 from being inserted into the guide rails 31.1, 31.2.

[0127] Furthermore, the longitudinal grooves 23.2 and 24.2 each include end stops 23.3 and 24.4 located on one side of the take-out surface. These end stops 23.3 and 24.4 function as insertion stops to limit the maximum insertion position in the receiving portion 32.

[0128] In fact, there are two different types of stops, and they are located in roughly the same position: at the ends of the longitudinal grooves 23.2 and 24.2.

[0129] Electrical contact rail of temperature sensor

[0130] Because the heating element 46 is used to primarily heat the first capsule 3, the first support 11 is preferably the second support 12 in order to support the walls 23.23, 24.23 of the grooves 23.2, 24.2.

[0131] In fact, a temperature sensor (not shown) is connected to the back of the diffuser plate 46.2 to measure the temperature near the first storage location 13 and therefore the first capsule 3.

[0132] Temperature sensors are typically CTN (negative temperature coefficient thermistors).

[0133] The temperature sensor should also be electrically connected to the mixer 6 (especially ultimately to the processor for data collection) and the battery 44 provided with the mixer 6 to power the temperature sensor. For this purpose, a first supplementary electrical contact track 46.51 is provided at the first contact surface 23. This first supplementary electrical contact track 46.51 differs from the first electrical contact track 23.1. More precisely, the first supplementary electrical contact track 46.41 is provided in the first recess 23.2, on the sidewall 23.23, i.e., on the sidewall formed by the first support portion 11.

[0134] Similarly, a second supplementary electrical contact track 46.52 is disposed in the second groove 24.2.

[0135] The two supplementary electrical contact tracks 46.51 and 46.52 are also advantageously offset. In a specific example, supplementary electrical contact track 46.51 and electrical contact track 24.1 are on the same horizontal plane, and supplementary electrical contact track 46.52 and electrical contact track 23.1 are on the same horizontal plane.

[0136] Figure 2A 3A, 3B, 4A, 4B, and 5 show these orbitals.

[0137] Positioning Department

[0138] The storage device 5 includes a positioning part 17, which is used to ensure the correct positioning of the first and second capsules 3,4, that is, the "correct" capsules 3,4 are placed in the "correct" storage positions 13,14. Figure 2A (See in different forms 5). The positioning part 17 is preferably located at the end of the openings 11.2, 12.2 to prevent unwanted passage of unwanted connectors 3.2, 4.2.

[0139] The positioning part 17 includes at least one door leaf 17.1 that opens toward the outside of the storage device 5 (preferably two door leaves on each side, as shown in the figure; preferably, the two door leaves 17.1 have a bar-style configuration, i.e., they are hinged toward the outside of the storage device via hinges).

[0140] Specifically, the positioning part 17 fulfills two different functions.

[0141] Door leaf 17.1 includes an opening 17.2 having a shape complementary to the female connector 3.4 of the first capsule 3, allowing insertion into the opening 8.2. Furthermore, door leaf 17.1 includes a stop 17.3 that helps to define the opening 17.2 to prevent a second connector 4.2, which is laterally longer than the first connector 3.2, from being inserted into the opening 8.2. In fact, if an attempt is made to insert the second capsule 4 into the first storage position 13, the end of the second connector 4.2, i.e., a portion of the male connector 4.4, abuts against the stop 17.3.

[0142] When the storage device 5 is in the closed position, the positioning part 17 blocks the second storage position: preferably through the opening 12.2 and also through the stop 17.3. Conversely, when the storage device 5 is in the open position, that is, when the second housing 9 rotates on its hinge, it is released through the opening 12.2.

[0143] Finally, since the door 17.1 opens outward, it is not functionally obstructed when the first and second capsules 3,4 are removed from the storage device 5 (both simultaneously, as they are fixed together).

[0144] Depending on the design of the relative movement of the parts, the positioning part 17 can be fixed to either the first support part 11 or the second support part 12 (as shown in the figures): if the second support part 12 is fixed to the second housing 9 (and therefore rotatably movable relative to the first support part 11), then it is preferable to fix the positioning part to the first support part 11. In other words, there is no difference.

[0145] The return spring 17.4 keeps the positioning part 17 in the default position, i.e., the closed position.

[0146] Pressing element - blade

[0147] Especially Figure 2B As shown in 3A, 3B, and 5, the storage device 5 also includes a first pressing element 19 and a second pressing element 21. The first pressing element 19 is configured to enter the interior of the second storage position 14, i.e., to apply pressure to the first capsule 3 and more specifically to the first deformable compartment 3.1. The second pressing element 21 is configured to enter the interior of the first storage position 13, i.e., to apply pressure to the second capsule 4 and more specifically to the second deformable compartment 4.1.

[0148] The first pressing element 19 (or the second pressing element 21) is preferably mounted on the first support 11 (or the second support 12) and is movable between an ineffective position, i.e., an unfolded position, and an effective position, i.e., a folded position, in which the first or second storage position 13, 14 can be easily accessed for the first or second capsule 3, 4 (see...). Figure 2B In the effective position, the first pressing element 19 (or the second pressing element 21) enters the interior of the first storage position 13 (or the second storage position 14), that is, the first pressing element (or the second pressing element) can apply pressure on the first deformable compartment 3.1 of the first capsule 3 (or the second deformable compartment 4.1 of the second capsule 4).

[0149] The first pressing element 19 (or the second pressing element 21) is advantageously rotatably mounted about the hinge 19.1 (or hinge 21.1). The hinge 19.1 (or hinge 21.1) is located opposite the opening 8.2 (or opening 8.1) of the first housing 8 (or second housing 9). Hinges 19.1 and 21.1 are therefore both located near the removal surface of the storage device 5.

[0150] Pressing elements 19, 21 each have flat inner surfaces 19.2, 21.2 to form rotating blades. Each flat inner surface 19.2, 21.2 mates with its first or second capsule 3, 4. As pressure is applied to the pressing element, the space between the blades and the mounting surfaces 11.1, 12.1 gradually and continuously decreases. When the first or second capsule 3, 4 is installed, the outlet hole 3.6 and the connecting portions 3.2, 4.2 are located on opposite sides of the hinge 10: this allows for efficient expulsion of cream from the first or second capsule 3, 4 while avoiding any unwanted retention areas inside the first or second capsule.

[0151] In order to keep the pressing elements 19, 21 in the default open position (i.e., when the storage device 5 is not driven or when the second housing 9 is in the pivot position), the return mechanism 21.3, such as when the spring is set to abut against the first or second housing 8, 9, Figure 5 The recovery mechanism 21.3 may tend to push against the blade that extends slightly on the other side of the hinge 21.1.

[0152] In use, as will be described later, the two pressing elements 19, 21 are sequentially actuated to allow the cream to be stirred. Thus, the cream is transferred from the first or second capsule 3, 4 to another second or first capsule 4, 3.

[0153] Preferably, to optimize the operation of the blades, hinge 19.1 (or hinge 21.1) defines a rotation axis that is contained in the plane of mounting surface 11.1 (or mounting surface 12.1) and perpendicular to the longitudinal axis of the receiving device 5. When the capsule is not in use, the inner surfaces 19.2, 21.2 can rest against mounting surfaces 11.1, 12.1.

[0154] Similarly, hinges 19.1, 21.1 are preferably located at the end of the first or second storage position 13, 14.

[0155] To move the pressing elements 19, 21, the first and second housings 8, 9 preferably each include pressing points 8.3, 9.3 opposite the ends of the blades (to utilize a lever effect and minimize the force to be applied). These pressing points are configured to receive external forces, as will be described in more detail later. The pressing points 8.3, 9.3 are fixed to flexible regions 8.4, 9.4, which are deformable (made of an elastomer or the like). The flexible regions 8.4, 9.4 are themselves fixed to the remaining portion of the first or second housing 8, 9, which is made of a more rigid plastic.

[0156] The pressing points 8.3 and 9.3 are achieved by rigid materials (typically plastic).

[0157] Alternatively (not shown), the first and second housings 8, 9 have two holes, preferably opposite the ends of the blades, to allow free access to the pressing elements 19, 21.

[0158] The user can grasp the storage device 5 with their hand and simultaneously press the pressure points 8.4 and 9.4, for example, with their thumb and index / middle finger. The simultaneous pressure allows the cream in the first and second capsules 3 and 4 to be guided toward the output port 3.6.

[0159] In another embodiment not shown, the housing 5 is integrated with the mixer 6, and the blades can be directly integrated into the mixer 6.

[0160] Keep the stop

[0161] To prevent the receiving device 5 from being removed from the receiving portion 32 during the stirring process, a retaining mechanism 50, which will be described in detail later, is provided in the manufacturing equipment 2. To ensure that the retaining mechanism 50 has a support point on the receiving device 5, a retaining stop 9.6 is provided in one of the first or second housings 8, 9 (in... Figure 2A 2B, 3A, 3B, 4B, and 5 are on the second shell 9). The retaining stop 9.6 mainly corresponds to the radially extending protrusion, that is, the protrusion extending in a plane perpendicular to the longitudinal direction X. The retaining stop can be located at any position along the height of the receiving device 5. In the illustrated embodiment, the retaining stop 9.6 is located near the insertion surface.

[0162] For example, for ergonomic reasons, another stop can be installed on another housing.

[0163] Hold the handle

[0164] To allow the user to hold the storage device 5 when it is inserted into the receiving portion 32, grip handles 8.7, 9.7 are provided on each of the first and second protective shells 8, 9 (especially visible in Figures 1, 2B, 4A, 4B). These grip handles 8.7, 9.7 are located at the extraction surface, which is the surface that can be accessed when the storage device 5 is placed.

[0165] The grip handle 8.7, 9.7 can be simply formed by a radially extending protrusion, that is, a protrusion extending in a plane perpendicular to the longitudinal direction X, and long enough that a portion of the user's knuckles can be lifted from above.

[0166] Connect button

[0167] As noted above, the actuating surfaces 8.1, 9.1, and more specifically the first and second protective housings 8, 9, each include pressing points 8.3, 9.4 to transmit force toward the inward pressing elements 19, 21. These pressing points 8.3, 9.4 are formed in the flexible regions 8.4, 9.4.

[0168] When the receiving device 5 is moved to the closed position, the connecting joints 3.4, 4.4 are opposite each other and partially nested. To establish a sealed and reliable fluid connection between the first and second capsules 3, 4, a connecting mechanism 52 is provided in the manufacturing apparatus 2. This connecting mechanism 52 applies a force toward the receiving device 5. This connecting mechanism 52 simultaneously allows the establishment of a fluid connection between the first and second capsules 3, 4 under the force applied by the connecting mechanism 52, and also prevents any undesirable disconnection of the first and second capsules 3, 4 under the pressure generated by the stirring of the first and second capsules 3, 4. This will be described later.

[0169] One (or even both) of the first or second protective shells 8, 9 includes a connecting button 9.8 that is active toward the second storage position 14. Figure 2A (2B, 3A, 3B, 4A, 4B, 5). More precisely, the connecting button moves toward the area near the opening 9.2 because the connecting button 9.8 is used to press the second capsule 4 near the connecting portion 4.2. For this purpose, the connecting button 9.8 is fixed to a flexible area, which may be the flexible area 9.4 of the pressing point 9.3. It should be noted here that the connecting button 9.8 is different from the pressing point 9.3.

[0170] The connecting button 9.8 is preferably rigid in order to better transmit the force of the connecting mechanism 52 to the first and second capsules 3,4, so that the first and second capsules are kept connected.

[0171] mixer

[0172] More specifically, such as Figure 6 As shown in 7A, 7B, 8A, 8B, 8C, 9, 10A, 11A, 11B, and 11C, the mixer 6 includes a support portion 31 and a receiving portion 32, the receiving portion being at least partially defined by the support portion 31 and configured to at least partially house the receiving device 5. Figure 1AIn the embodiment shown in 1B, the mixer 6 and the storage device 5 are configured such that when the storage device 5 is housed in the receiving portion 32, the storage device 5 extends at least partially outside the mixer 6. The support portion 31 serves as a base, defining the entirety of the fixing element when the mixer 6 is placed on a support (table, work surface, etc.), regardless of whether the mixer is used or not. The support portion 31 of the mixer 6 also includes a housing 33 and an insertion opening 34 leading into the receiving portion 32, through which the storage device 5 is configured to be inserted into the receiving portion 32. Advantageously, the insertion opening 34 is arranged in the central portion of the upper surface of the base 33 and is configured to be oriented upwards when the mixer 6 is placed on a horizontal support surface (table, work surface, etc.).

[0173] The base 33 also serves as the housing, which is a desirable design for the mixer. The base 33 may include a lower base and an upper base.

[0174] Actuation system

[0175] The mixer 6 also includes an actuation system 35, which is pivotally mounted on the support 31 about a generally vertical pivot axis 36 when the mixer 6 is set on a horizontal support surface (table, work surface, etc.). Figure 6 8A, 8B, 8C, 9, 10A).

[0176] Preferably, the actuation system 35 performs a reciprocating motion about the pivot axis 36 along a maximum angular travel of 45°. The motion thus consists of a maximum rotation +45°, then -45°, and so on. The movement of the actuation system is along a rated travel C35 (not shown), which, when rotating about the pivot axis 36, combines with the maximum angular travel. The rated travel C35 of the actuation system 35 is defined as the travel between the two extreme positions of the actuation system 35. The intermediate position of the actuation system 35 is defined between these two extreme positions, corresponding to the insertion position, in which the receiving device 5 can be positioned inside the receiving portion 32 of the mixer 6 without being disturbed by the actuation system 35.

[0177] The mixer 6 further includes a drive motor 39 mounted on the support 31. The drive motor 39 is configured such that the actuation system 35 pivots about a pivot axis 36 and within a predetermined angle range. Preferably, the drive motor 39 rotates only in a single direction.

[0178] The actuation system 35 includes a first actuation member 37 and a second actuation member 38. The first actuation member may include a first actuation finger 37.1 configured to transmit pressure to a first capsule 3. The second actuation member may include a second actuation finger 38.1 opposite to the first actuation member 37 and configured to transmit pressure to a second capsule 4.

[0179] When the storage device 5 is stored in the mixer 6, and more precisely in the receiving portion 32, the first and second actuating members 37, 38 are configured to be disposed on both sides of the receiving portion 32 and thus on both sides of the storage device 5.

[0180] Actuating members 37 and 38 have at least one position in which the actuating members are at least partially inside the receiving portion 32. In an intermediate position of the actuation system 35, the actuating members 37 and 38 are arranged relative to the receiving portion 32 to allow the receiving device 5 to be positioned inside the receiving portion 32 of the mixer 6; this is the insertion position.

[0181] More specifically, the first and second actuating members 37, 38 are configured to apply pressure, respectively and alternately, to the first and second pressing elements 19, 21, so as to transmit pressure, respectively and alternately, to the first and second compartments 3.1, 4.1. In particular, the first and second actuating members 37, 38 are configured to engage with the first and second pressing points 8.3, 9.3 of the first and second protective housings 8, 9, respectively, or directly with the pressing elements 19, 21.

[0182] The actuation stroke C37 for the first actuating member 37 and the actuation stroke C38 for the second actuating member 38 are defined.

[0183] The actuation stroke C37 is defined as the stroke of the first actuating member 37 between the intermediate position of the actuation system 35 and the maximum actuation position of the first actuating member 37, in which the first actuating member 37 presses the first pressing element 19 to the maximum.

[0184] Conversely, the actuation stroke C38 is defined as the stroke of the second actuating member 38 between the intermediate position of the actuation system 35 and the maximum actuation position of the second actuating member 38, in which the second actuating member 38 presses the second pressing element 21 to the maximum.

[0185] Preferably, the motion of the actuation system 35 can be tracked using various sensors, particularly Hall effect sensors. More specifically, each of the first actuation member 37 and the second actuation member 38 may include a magnet for interacting with the stationary Hall effect sensor. Advantageously, the Hall effect sensor may be directly mounted on the control unit 45, as will be described later. Figure 12Therefore, the control unit 45 can track the motion of the actuation system 35, and similarly can track the motion of each of the first and second actuation members 37, 38. The control unit 45 can also, for example, determine the position of each of the first and second actuation members within its respective actuation stroke C37, C38 precisely by using multiple Hall effect sensors.

[0186] According to the embodiment shown in Figures 1 to 12, the first and second actuating members 37, 38 extend in substantially the same extending plane and converge relative to the pivot shaft 36.

[0187] like Figure 6 As shown in 8A, 8B, 8C, and 9, the actuation system 35 has a generally annular shape that defines an opening around the receiving portion 32. In this embodiment, the actuation system 35 is primarily formed from a single component that includes an opening for receiving a shaft defining a pivot shaft 36.

[0188] The first actuating member 37 and the second actuating member 38 are each disposed on opposite sides of the actuation system 35. Thus, the actuation system 35 has two surfaces extending on opposite sides: actuating members 37 and 38, an opening for the pivot shaft 36, and a drive mechanism with grooves, which will be described later.

[0189] Actuating members 37 and 38 may each include drive supports 37.3 and 38.3, which are engaged on one side at the pivot 36. On the other side, a connecting portion 36.1 is defined, which connects the two drive supports 37.3 and 38.3. The connecting portion 36.1 may be fixed to the drive supports 37.3 and 38.3 or made of the same material.

[0190] Preferably, the two actuating members 37, 38 rotate about the same pivot axis 36. In this case, it is preferable to rotate two drive supports 37.3, 38.3 that are integrally connected.

[0191] However, a pivot axis may be provided for each actuating component 37, 38; however, some simple adaptation should be provided.

[0192] Alternatively, in embodiments not shown, the actuating member translates.

[0193] spring

[0194] The actuation system 35 moves along the rated stroke C35 to apply force to the storage device 5.

[0195] However, clearances related to manufacturing tolerances in the drive train can interfere with force transmission by varying the position of the actuation system 35. Therefore, once the stroke ends, a few micrometers may be missing or conversely, a few micrometers may be added. This can cause insufficient compression of the manufacturing equipment 2 or, conversely, damage to the manufacturing equipment 2.

[0196] To overcome this problem, the actuation system 35 may include springs 37.4, 38.4 (specifically in...) Figure 8A (See 8B, 8C). Specifically, springs 37.4, 38.4 are configured to compress when the actuation system 35 reaches near the end of its rated stroke C35 and the actuation fingers 37.1, 38.1 abut against the flat surfaces 3.7, 4.7 of the capsule. Springs 37.4, 38.4 thus generate a force that tends to separate the actuation members 37, 38 of the receiving device 5.

[0197] More precisely, each actuating component 37, 38 includes springs 37.4, 38.4.

[0198] Springs 37.4 and 38.4 can be located in different positions. In an embodiment not shown, springs 37.4 and 38.4 are located at the "free" ends of fingers 37.1 and 38.1.

[0199] In another embodiment, preferably, because the springs are concealed, the springs 37.4, 38.4 are mounted between the fingers 37.1, 38.1 and the drive supports 37.3, 38.3. Thus, because the springs are behind the base, they are not accessible to the user.

[0200] To accommodate the spring in this position, for each actuating member 37, 38, an arm 37.2, 38.2 is simply provided that is movably mounted relative to the drive supports 37.3, 38.3. This means that 37.1, 38.1 are thus integrally mounted with the arms 37.2, 38.2.

[0201] In particular, Figure 8A In the embodiments shown in 8B, 8C, and 9, arms 37.2 and 38.2 are rotatably movable relative to drive supports 37.3 and 38.3 via hinges 37.5 and 38.5. Springs 37.4 and 38.4 are positioned between arms 37.2 and 38.2 and drive supports 37.3 and 38.3.

[0202] Springs 37.4 and 38.4 are therefore compressed, meaning that the springs are not compressed in their uncompressed or non-stressed positions. The springs are compressed in the translational or rotational directions of the actuating members 37 and 38.

[0203] Springs 37.4 and 38.4 can be helical, leaf springs, or even springs made of elastic materials or elastic assemblies (elastomers, bubbles, etc.).

[0204] Rotary drive

[0205] according to Figure 6 In the embodiments shown in 8A, 8B, 8C, and 9, the mixer 6 further includes a cam 41 in the form of a drive wheel or arm, which is rotatably connected to the output shaft 39.1 of the drive motor 39 and configured to be rotatably driven about a rotation axis 41.1 of the cam. The cam 41 is mounted on the support 31. To allow reciprocating motion with a large lever arm, preferably, the pivot 36 and the cam 41 are on opposite sides of the receiving portion 32.

[0206] The cam 41 is equipped with a drive finger 42, which is eccentric relative to the rotation axis 41.1 of the cam.

[0207] Cam 41 is typically driven by drive motor 39 via one or more belts. In this case, starting from drive motor 39 and output shaft 39.1 with pulleys mounted, the transmission chain is as follows: belt 39.2, pulley 39.3 connected to pulley 39.4 via a shaft, belt 39.5, cam 41.

[0208] The drive finger 42 is housed in a drive recess 43 provided on the actuation system 35. Specifically, the drive recess 43 is constructed in the connection portion 36.1. The drive recess 43 is elongated and extends in a direction substantially parallel to the pivot axis 36. This configuration of the mixer 6 allows for reciprocating motion of the actuation system 35 while ensuring that the drive motor 39 always rotates in the same direction of rotation, thus eliminating the need for an expensive control system for the drive motor 39.

[0209] The drive groove 43 extends along its depth toward the pivot shaft 36.

[0210] The connection between the drive groove 43 and the drive finger 42 will now be described. Given the rotation of the actuation system 35, the alignment of the drive groove 43 and the drive finger 42 is variable, meaning that simple adjustments could jam the system. Conversely, misalignment would result in gaps that generate noise and introduce a delay at the end of each stroke.

[0211] To address this issue, a ball-and-socket joint is provided between the drive finger 42 and the drive groove 43, which allows for the aforementioned misalignment.

[0212] Specifically, ball 42.1 is mounted on drive finger 42, and the ball is housed in ring 43.1. The connection between ball 42.1 and ring 43.1 is a ball-and-socket joint. Ring 43.1 itself is housed in drive groove 43, and the ring is movably mounted in drive groove along a direction parallel to pivot axis 36 (and thus along the length of drive groove 43). Finally, ball 42.1 is movably mounted along drive finger 42. The arrangement of these different connections can be different, meaning that the ring can also move movably along the depth of the groove and the ball is thus fixed on drive finger.

[0213] Therefore, the complete connection between the drive finger 42 and the actuation system 35 sequentially includes a guide rail, a ball joint, and a guide rail perpendicular to the other guide rail. Thus, in the motion torque, note that force is transmitted only in one of the six torque components, namely the translational component tangential to the rotational motion of the actuation system 35, i.e., the component that allows the actuation system 35 to rotate. The motion equivalent is the spherical-surface connection (also known as a point connection).

[0214] To avoid making the above connection more complicated and useless, the rotation axis 41.1 of the cam and the pivot axis 36 are preferably orthogonal. This allows for a drive finger 42 that performs circular motion in a plane parallel to the pivot axis 36.

[0215] The movement of some of the connected settings can be easily achieved using plastic slide rails / plastic that wear out slowly enough to ensure a satisfactory lifespan.

[0216] According to an embodiment of the invention, the mixer 6 can be configured such that the rotational drive actuation portion 35 of the drive motor 39 in the first rotational direction pivots in the first pivotal direction, and the rotational drive actuation portion 35 of the drive motor 39 in the second rotational direction opposite to the first pivotal direction pivots in the second pivotal direction opposite to the first pivotal direction.

[0217] Eccentricity of pivot axis

[0218] Actuating components 37 and 38 move along actuation strokes C37 and C38, respectively.

[0219] However, in the embodiment shown in the figure, one of the two actuating members 37, 38 has a consistent actuation stroke C37, C38, the length of which is significantly greater than the actuation stroke length of the other actuating member. This difference in actuation strokes C37, C38 allows for better mechanical and electrical management of the applied force to deform the first capsule 3 relative to the second capsule 4. In fact, as Figure 2BAs shown, the first capsule 3 has a greater thickness than the second capsule 4, which means that more space is needed on the side of the thickest capsule, and the pressing element 19 will contact and work faster than the pressing element 21.

[0220] To achieve this difference in stroke, several solutions can be considered. One solution involves having a drive groove 43, which is uncentered in the connecting portion 36.1.

[0221] especially Figure 8A Another solution shown in 8B, 8C, and 9 aims to make the pivot axis 36 eccentric. On the other hand, the rotation axis 41.1 of the cam does not intersect the pivot axis 36. This results in a difference in stroke between the two actuating members 37 and 38 when the cam 41 completes one full revolution. A distance (orthogonal, i.e., by orthogonal projection) between the rotation axis 41.1 of the cam and the pivot axis 36 of 1% to 5% of the distance between the drive recess 43 and the pivot axis 36 is sufficient and does not significantly affect the overall symmetrical appearance. In absolute terms, a distance between 1 mm and 2 mm is suitable.

[0222] The eccentricity can also be defined by the rotation axis of the receiving part 32 relative to the cam 41: therefore, the end position of the actuation system 35 is not centered around the receiving part 32.

[0223] The eccentricity can also be defined relative to the first and second mounting surfaces 11.1, 12.1 or relative to the positions of the first and second capsules 3, 4 in the receiving portion 32: by means of the flat surfaces 3.7, 4.7, which thus define the dummy surfaces in the receiving portion 32. The maximum distance from the first actuating member 37 to the surface of the flat surface 3.7 is greater than the maximum distance of the second actuating member 38 relative to the flat surface 4.7.

[0224] Therefore, in a variant example, the pivot axis 36 is contained in a plane equidistant from the two mounting surfaces 11.1, 12.1.

[0225] Under the influence of eccentricity, the first actuating finger 37.1 is advantageously longer than the second actuating finger 38.1. This is particularly due to the fact that the eccentricity compensates for the end positions of the actuating fingers 37.1 and 38.1. More precisely, the actuating fingers 37.1 and 38.1 operating on the thicker first or second capsules 3 and 4 have a greater length than the other actuating fingers 37.1 and 38.1.

[0226] Figure 8AAnother solution shown aims to avoid limiting the intermediate position of the actuation system 35 at either the high or low dead center of the cam 41. In fact, by selecting the intermediate position of the actuation system 35 at a non-zero angle Ag (typically between 5° and 30°) relative to the 12 o'clock direction (when the mixer 6 is placed on a horizontal support), the distribution of the actuation strokes C37 and C38 is staggered. Furthermore, it should be noted that another intermediate position is thus obtained for the angle Ag' corresponding to Ag' = 180° - Ag.

[0227] In fact, the actuation strokes C37 and C38 at cam 41 correspond to a rotation from angle Ag to the nearest 90° (i.e., the 3 o'clock or 9 o'clock direction, when the mixer 6 is placed on the horizontal support), and then correspond to a rotation from angle Ag' to 270°. Since Ag and Ag' are not at 0° and 180° (12 o'clock and 6 o'clock directions), it is immediately noticeable that the strokes C37 and C38 are not equal. Regarding the complete rotation of cam 41, the first actuation stroke C37 is passed in the first direction, then in the second direction, then in the first direction, then in the second direction, then in the second direction, then in the second direction, i.e., two rated strokes C35.

[0228] Contact rail of the mixer

[0229] As mentioned above, the mixer 6 itself also includes electrical contact tracks 31.11, 31.12 and electrical contact tracks 31.51, 31.52. The electrical contact tracks 31.11, 31.12 are configured to engage with the electrical contact tracks 23.1, 24.1 of the longitudinal grooves 23.2, 24.2 of the storage device 5. The electrical contact tracks 31.51, 31.52 are configured to engage with the supplementary electrical contact tracks 46.51, 46.52 of the longitudinal grooves 23.2, 24.2.

[0230] These electrical contact rails are mounted on guide rails 31.1 and 31.2. Figure 1A The guide rails 31.1 and 31.2 are integrally connected to the support 31 and mounted on the two connecting sides of the receiving portion 32. The positions of the electrical contact rails 31.11 and 31.12 (and 31.51 and 31.52) on the guide rails 31.1 and 31.2 are complementary to the positions of the electrical contact rails 23.1 and 24.1 (and 46.5 and 46.52) on the connecting surfaces 23 and 24 of the receiving device 5. The guide rails 31.1 and 31.2 help to define the receiving portion 32. The guide rails are located, for example, on the edge and are preferably fixed to the support 31 along their entire length.

[0231] The position of the electrical contact rails 31.51, 46.51, and 31.52, 46.52 on two opposing and spaced-apart rails 31.1, 31.2 has the advantage that once liquid flows onto one of the rails 31.1, 31.2 by gravity, the risk of short circuit is limited.

[0232] Blocking mechanism, connecting mechanism, and extraction mechanism

[0233] The mixer 6 also includes a holding mechanism 50, a connecting mechanism 52, and a clamping mechanism 54. Figure 10A , 10B, 10C, 10D, 10E, 10F, 11A, 11B, 11C).

[0234] Each of these mechanisms has its own and independent function. However, these mechanisms can advantageously be driven simultaneously by the same auxiliary motor 40.

[0235] The function of the retaining mechanism 50 is to prevent the storage device 5 from being removed during stirring.

[0236] The retaining mechanism 50 is movably mounted between the insertion position and the retaining position relative to the support portion 31. In the insertion position, the retaining mechanism 50 allows the receiving device 5 to be inserted into and removed from the mixer 6. In the retaining position, the retaining mechanism 50 prevents the receiving device 5 from being removed (and thus prevents the receiving device from being inserted).

[0237] The retaining mechanism 50 includes a movable element 50.1 that moves between the two positions described above, extending within the receiving portion 32 in the retaining position. Specifically, in the retaining position, the movable element 50.1 engages with a retaining stop 9.6 to prevent translational movement of the receiving device 5 intended for removal from the mixer 6 (in fact, in the case of removal, the retaining stop 9.6 abuts against the movable element 50.1 and locks). For this purpose, when the receiving device 5 is placed in the mixer, the movable element 50.1 and the retaining stop 9.6 are positioned near the retaining position, preferably less than 2 mm.

[0238] exist Figure 10A In the embodiments shown in 10B and 10C, the movable element 50.1 is a wheel, namely a retaining wheel, which moves about a wheel rotation axis 50.2. The wheel 50.1 has at least two different radii, the smaller radius being configured not to extend into the receiving portion 32 in the insertion position, and the larger radius being configured to extend into the receiving portion 32 in the retaining position so as to contact the retaining stop 9.6 in the case of removal.

[0239] Wheel 50.1 is preferably circular with a flat portion that allows for insertion position.

[0240] Wheel 50.1 is mounted on a shaft extending along the wheel's axis of rotation 50.2. The shaft includes a gear 51 or pulley, which is connected to at least one additional gear or additional pulley 51.1.

[0241] Alternatively, the movable element 50.1 may be translated by means of a gear 51, for example, via a gear-rack system.

[0242] The function of the connecting mechanism 52 is to establish a sealed connection between the first and second capsules 3, 4 by pressing the connecting button 9.8 on the second protective shell 9 and to ensure that the first and second capsules are well nested through their connecting joints 3.4, 4.4.

[0243] The connecting mechanism 52 is movably mounted relative to the support portion 31 between an insertion position and a connection position. In the insertion position, the connecting mechanism 52 allows the insertion and removal of the receiving device 5. In the connection position, the connecting mechanism 52 locks the first and second capsules 3,4.

[0244] The connecting mechanism 52 includes a connecting element 52.1 that moves between the two positions described above, extending within the receiving portion 32 in the connecting position. Specifically, in the connecting position, the connecting element 52.1 engages with a connecting button 9.8, which moves within the second storage position 14. Therefore, when the storage device 5 is installed in the mixer 6, the connecting element 52.1 and the connecting button 9.8 are opposite each other.

[0245] exist Figure 10A In the embodiments shown in 10B and 10C, the connecting element 52.1 is a wheel, i.e., a connecting wheel, which moves about a wheel rotation axis 52.2, which preferably coincides with a wheel rotation axis 50.2. The wheel 52.1 has at least two different radii, with the smaller radius configured not to extend into the receiving portion 32 in the insertion position, and the larger radius configured to extend into the receiving portion 32 in the connection position so as to contact and press the connection button 9.8.

[0246] Wheel 52.1 preferably has an elliptical shape in a plane.

[0247] Wheel 52.1 is mounted on a shaft extending along the wheel's axis of rotation 52.2. This shaft includes a gear or pulley connected to at least one additional gear or pulley 51.1. The shaft and gear are preferably identical to shaft and gear 51. Thus, a first sub-unit of rotatable connection is obtained.

[0248] Alternatively, the connecting element 52.1 may be moved by means of gear 51 via a gear-rack system, for example.

[0249] The connecting mechanism 52 differs from the actuation system 35. This is due to its different position (e.g., different height) within the mixer 6. Similarly, the storage device 5 includes press points 8.3 and 9.3, which differ from the connecting button 9.8.

[0250] The function of the clamping mechanism 54 is to clamp the output channel 3.5 of the first capsule 3 during the mixing process. In fact, the pressure inside the first or second capsules 3,4 can cause undesirable output of the cream. In this case, the cream diffuses within the mixer 6, which is to be prevented. This is in Figure 11A As shown in 11B and 11C.

[0251] The clamping mechanism 54 moves relative to the support portion 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 output channel 3.5.

[0252] The clamping mechanism 54 includes a clamping wheel 54.1 that rotates about a clamping wheel axis 54.2.

[0253] The mixer 6 also includes a fixed guide wall 54.3 (integrated with the support 31, or even made of the same material as the support) and a clamping wall against which a clamping wheel 54.1 rolls or slides, and which is clamped in the clamping position. The clamping wall is advantageously part of the guide wall 54.3. Several variations are distinguished: one variation in which the clamping wheel 54.1 is positioned close to the guide wall 54.3 toward the clamping position; another variation in which the distance is constant or variable; and a variation in which the clamping wall has a special recess to capture the clamping wheel 54.1 (this is possible due to the translational movement of the clamping wheel 54.1, as will be seen below).

[0254] The teeth 54.11 present on the clamping wheel 54.1 (in practice, the wheel includes a circular or generally circular portion and teeth, the circular or generally circular portion clamping the first capsule 3, the teeth preferably being below the circular portion) can engage with the teeth 54.31 in the guide wall 54.3, causing the clamping wheel 54.1 to roll against the guide wall 54.3. Furthermore, due to the teeth 54.11 and 54.31, the clamping wheel 54.1 against the clamping wall 54.3 has rolling motion without slippage, which allows for the avoidance of dangerous slippage with a poor clamping output channel 3.5. Finally, due to the teeth 54.11 and 54.31, the distance between the clamping wheel 54.1 and the guide wall 54.3 (excluding the teeth, i.e., the average distance) can be reduced to almost zero below the first capsule 3 while maintaining rolling motion against the guide wall 54.3.

[0255] To allow this transmission, clamping wheel 54.1 is mounted on arm 54.5 and preferably rotatably mounted, the arm itself rotating about arm rotation axis 54.51.

[0256] Arm 54.5 is integrated with a gear (or pulley) or gear section 54.52, which itself is connected to a common gear 40.1 via various gears or pulleys. Therefore, arm 54.5 is driven to rotate by the same auxiliary motor 40.

[0257] To ensure clamping in the clamping position, including when the auxiliary motor 40 is no longer energized, the clamping wheel 54.1 is radially movably mounted along the arm 54.5. A resetting mechanism 54.4, located between the clamping wheel 54.1 and the arm 54.5, tends to separate the clamping wheel 54.1 from the arm's rotation axis 54.51, and therefore tends to bring the clamping wheel 54.1 against the guide wall 54.3. More specifically, an intermediate support is provided containing the rotation axis 54.2 of the clamping wheel 54.1. This support is movably translated relative to the axis 54.5. In the intermediate support, a sliding connection with a pin 54.42 that slides in a groove 54.53 on the axis 54.5 allows for guiding translation and also advantageously allows for limiting translational movement.

[0258] The recovery mechanism 54.4 therefore compresses, wherein, by default, the recovery mechanism is not compressed (or very little compressed). A coil spring, leaf spring, or other type of spring may be suitable.

[0259] Thanks to the recovery mechanism 54.4, the clamping wheel 54.1 can remain 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 (the distance can gradually decrease toward the area where the output channel 3.5 is located).

[0260] Shared driver

[0261] Preferably, the retaining mechanism 50, the connecting mechanism 52, and the clamping mechanism 54 are simultaneously driven by a common drive, as described in the following embodiment. The retaining mechanism 50 is driven by a gear 51 that is connected to at least another gear 51.1. Figure 10A ,10B).

[0262] The connecting mechanism 52 is driven by at least one gear connected to another gear, preferably gear 51 and another gear 51.1. Figure 10A ,10B).

[0263] The clamping mechanism 54 is driven by the gear part 54.52.

[0264] Different drive chains can be configured, while a common gear 40.1 is preferably configured to drive another gear 51.1 and gear section 54.52.

[0265] like Figure 11A As shown in 11B and 11C, a common gear 40.1 is located on the output shaft of the auxiliary motor 40. This common gear meshes directly with gear 51.1, which is mounted on a shaft including another gear 51.2. Gear 51.2 itself meshes with gear portion 54.52. Therefore, a very simple drive train is achieved, with a minimum number of gears, and thus minimal frictional loss, minimal risk of damage, and very small backlash.

[0266] Due to the common gear 40.1 located on the output shaft of the auxiliary motor 40, at least two of the three mechanisms 50, 52, and 54 are simultaneously in the insertion, holding, connection, or clamping position. The same auxiliary motor 40 thus drives all three mechanisms, which constitutes a major simplification of the mixer 6 and its operating principle.

[0267] Visual and audio displays

[0268] The mixer 6 advantageously includes a screen 60 that allows for the exchange of information with the user and / or a speaker (Figures 1A, 1B, 7).

[0269] The screen 60 is preferably touch-sensitive to avoid the need for physical buttons. The screen allows the user to indicate the start and end of the cycle. The screen 60 can also display the end of the cycle, accompanied by, for example, an audible alert.

[0270] Power supply and control unit

[0271] According to an embodiment of the invention, the mixer 6 further includes a power supply (not shown) configured to power the mixer 6, particularly the drive motor 39 and the auxiliary motor 40. The power supply advantageously, and even exclusively, includes at least one rechargeable battery 44. Figure 7B In the example shown, the rechargeable battery 44 is advantageously composed of a lithium-ion battery having two battery cells, which provides a rated output voltage of 7.4V.

[0272] like Figure 12As shown, the mixer 6 also includes a control unit 45, which includes, for example, a controller such as a microcontroller or processor 45.1, configured to control the operation of the manufacturing equipment 2, more specifically controlling the operation of the drive motor 39, auxiliary motor 40, heating element 46, temperature sensor, and screen 60 (preferably the processor for the screen), as well as all sound or visual devices. The control unit 45 advantageously includes a non-volatile type of memory 45.2 storing instruction lines in the form of a program to be executed by the controller or processor 45.1, particularly for implementing some of the steps described in the following methods.

[0273] Other implementation methods

[0274] In a variant, the holding device 5 is integrated with the mixer 6. Therefore, it is only necessary to insert the first or second capsule 3,4 into the first or second storage position 13,14. The receiving portion 32 is still defined, corresponding to the space occupied by the storage device 5.

[0275] Furthermore, in this variant, the actuating surfaces 8.1 and 9.1 may be absent: in this case, the actuating members 37 and 38 are pressed directly onto the first or second capsule 3 and 4.

[0276] How to use

[0277] At least one manufacturing method for producing a composition such as a cosmetic product using manufacturing equipment 2 will now be described. This manufacturing method is broken down into several sub-methods (referred to as "methods" for clarity), and one or more variations of this method will be described. Specifically, it is divided into a preparation method Ep, an initial method Ei, a mixing method Em, and a removal method Er.

[0278] Specifically, these methods (or variations thereof) are advantageously implemented using different embodiments of the manufacturing apparatus 2 described above. Preferably, most steps of methods Ei, Em, and Er are stored in a non-volatile type of memory 45.2 in the form of line-of-code instructions executable by processor 45.1.

[0279] The preparation method Ep includes a preparation step Ep1 for the entire use of the manufacturing equipment 2, which is designed to connect the manufacturing equipment to the power grid or charge the battery 44. Furthermore, this preparation step Ep1 can be performed before or after step Ep2, which involves placing the manufacturing equipment 2 on a flat support, and may include a power-on step if necessary.

[0280] Then the initial method Ei is implemented. In step Ei1 (“receiving step”), the processor of manufacturing equipment 2 receives a start command. This start command is typically generated by a user action (contact with touchscreen 60, buttons, switches, etc.).

[0281] Following step Ei1, in step Ei2 (“Inspection Step”), the method ensures that the actuation system 35 is in an intermediate position that allows insertion of the receiving device 5 or the first and second capsules 3,4. Typically, it should be ensured that the receiving portion 32 (for insertion of the receiving device 5) or the first or second receiving positions 13,14 (for insertion of the first or second capsules 3,4 without the receiving device 5) is not obstructed by the actuation system 35. During step Ei2, it is also appropriate to check that the clamping mechanism 54, the connecting mechanism 52, and the retaining mechanism 50 are not activated, i.e., in their respective insertion positions.

[0282] After step Ei2, the storage device 5, including the first or second capsule 3,4, can be manually inserted into the receiving part 32, or the first or second capsule 3,4 can be directly inserted.

[0283] Finally, in the subsequent step Ei3 (closing step), at least one of the clamping mechanism 54, the connecting mechanism 52, and the holding mechanism 50 is activated, i.e., they move. Step Ei3 includes, for example, a command issued by the processor to the auxiliary motor 40 to start the auxiliary motor, such that the auxiliary motor drives the three mechanisms when all three are connected to a common gear (or pulley) 40.1. The auxiliary motor 40 moves from a first position to a second position so that the clamping mechanism 52, the connecting mechanism 54, and the holding mechanism 50 move from their respective insertion positions to their respective clamping, connecting, and holding positions. Preferably, the auxiliary motor 40 remains in the second position at the end of step Ei3, even if the auxiliary motor is no longer powered.

[0284] Steps Ei1, Ei2, and Ei3 are specifically executed by processor 45.1.

[0285] Following the initial method Ei, the mixer 6 is ready to begin operating on the first and second capsules 3,4: this is the purpose of the mixing method Em and the extraction method Er.

[0286] The mixing method Em includes a first step Em1 (“initial step to move the actuation system”) in the preparation stage, during which the bonding solder of a capsule located further away from the heating element 46 (second capsule 4 in the figure) is broken up, and the capsule is compressed such that its contents are partially sent toward the capsule closer to the heating element 46. According to the given embodiment, the second actuating member 38 moves to break up the bonding solder in the second capsule 4 (the second capsule, for example, comprises an oil phase formulation). Thus, a portion of the contents of the second capsule 4 is sent toward one side of the first capsule 3, particularly into the connection channel 3.3 (because the bonding solder of the first capsule 3 has not yet been broken up). The second actuating member 38 preferably moves along its actuation stroke C38. For design simplification, a partial stroke sensor for the second actuating member 38 is not required.

[0287] In step Em2 (“the second step of moving the actuation system” or “the prestressing step”) of the preparation phase, the first actuating member 37 moves and holds its position along a portion of its actuation stroke C37, which is strictly less than this, to apply prestress to the first capsule 3 (which, for example, comprises an aqueous formulation) so that its flat surface 3.7 presses against the diffuser plate 46.2. This prestress allows for heat exchange between the diffuser plate 46.2 and the first capsule 3 during the subsequent step Em3 (“the heating step”). It should be noted that the pressing of the first capsule 3 against the diffuser plate 46.2 is performed due to the movement of the first actuating member 37 along its partial stroke without causing breakage of the bonding solder in the first capsule 3 (which would cause the formulation in the first capsule 3 to be sent toward the second capsule 4).

[0288] In step Em3 (“Heating Step”) of the preparation phase, heating element 46 is activated to generate heat toward the first capsule 3. Since heating element 46 is positioned on one side of the flat surface 3.7 of the first capsule 3 and the prestressing step has already allowed good thermal contact between the diffuser plate 46.2 and the first capsule 3, the heat provided by heating element 46 is well distributed on the contents of the first capsule 3. Step Em3 is thus activated without the need for the entire movement of actuating members 37, 38.

[0289] During step Em3 of the preparation stage, the temperature of the heating element 46 reaches a target temperature Tc between 80°C and 90°C. The purpose of this target temperature Tc is to bring the contents of the first capsule 3 to a target temperature Tc' that is also between 80°C and 90°C, and preferably about 85°C. In fact, it was observed that during this heating step Em3, the temperature of the contents of the first capsule 3 roughly corresponds to the target temperature Tc of the heating element 46, however with a slight time difference.

[0290] Then, in step Em3' (“mixing step”) of the stirring phase, the heating element 46 is deactivated, and the first actuating member 37 moves along its rated stroke to break up the bonding solder in the first capsule 3. The interruption of power supply to the heating element 46 prior to the activation of the first actuating member 37 allows for the integrity of the power supplied by the power source, which can be used to power the drive motor 39. This feature is particularly advantageous when the mixer 6 is powered by a low-power power converter or battery 44. In fact, this feature allows for the avoidance of insufficient power supplied to the drive motor 39 to allow the bonding solder in the first capsule 3 to break up (which would cause the device to jam), a step requiring a large motor torque. When the first actuating member 37 reaches the end of its actuation stroke C37, the contents of the first capsule 3 are sent into the second capsule 4, and the two formulations can thus circulate freely from the first or second capsule 3,4 toward the second or first capsule 4,3 via the connecting portions 3.2,4.2 in each reciprocating motion of the actuation system 35, and the original connecting solder present in each of the first and second capsules 3,4 has been broken.

[0291] Subsequently, steps Em4, Em5, and Em6 are continuous stirring steps, which may or may not involve heating (referred to as the stirring stage).

[0292] Step Em4 of the stirring phase (“unheated stirring step”) is designed to cause the actuating members 37, 38 to reciprocate without activating the heating element 46, i.e., without heating. During this step, the first and second capsules 3, 4 each deform at least once. According to an embodiment, step Em4 lasts for at least 1.4 seconds, preferably between 2 and 4 seconds. This unheated stirring step allows the drive motor 39 to start at a constant speed while also benefiting the overall power of the power supply.

[0293] Steps Em1, Em2, and Em3, Em3', Em4 alternate between actuating the actuation system 35 and heating the heating element 46. This is specifically caused by a power supply dedicated to either the actuation system 35 or the heating element 46. This unique alternation allows for the protection of the battery 44 by allocating high power moments. Indeed, the initiation of motion generates a large resistive torque, which requires a large motor torque, and the temperature rise also requires a large power: the battery 44 is therefore under heavy load. This alternation solution also allows for a reduction in component size, which is inherent in the manufacture of the mixer and is a design constraint on the battery.

[0294] Conversely, once the temperature is near the target temperature Tc' and once the actuation system 35 has arrived, the demand for battery 44 is reduced and allows for parallel power supply to heating element 46 and actuation system 35: this is the purpose of step Em5.

[0295] During step Em5 (“stirring step with heating”) of the stirring phase, the actuation system 35 remains active and the heating element 46 is activated to keep the formulation mixed at a temperature, preferably a target temperature Tc'. Therefore, the heating element is maintained at the target temperature Tc. This step Em5 lasts, for example, between 5 and 30 seconds, and preferably between 7 and 15 seconds. Although the battery 44 is required less for startup or temperature rise, the battery may tend to discharge rapidly during this duration-limited phase.

[0296] However, step Em5 is long enough so that the first and second capsules 3 and 4 can each deform multiple times and the emulsion obtained by mixing the formulation is satisfactory.

[0297] Between steps Em4 and Em5, the actuation system 35 is not stopped.

[0298] Subsequently, step Em6 (“cooling step with stirring”) of the stirring phase is performed. Alternatively, this step can be performed without stirring, but preferably the actuation system 35 is kept active to improve or maintain the homogenization of the formulation. During step Em6, the temperature of the cream decreases to a removal temperature Tr', which is between 35°C and 48°C, and preferably between 38°C and 42°C. In the illustrated embodiment, the removal temperature Tr' of the cream corresponds to the removal temperature Tr of the heating element 46, which is between 55°C and 60°C. During the cooling step, this temperature difference between the contents of the first and second capsules 3,4 and the temperature of the heating element 46 is explained in particular by the fact that, during stirring, the composition is only present in the first capsule 3 for a portion of the time, and therefore only relative to the diffuser plate 46.2 for a portion of the time, at which temperature measurement is performed.

[0299] The simplest technique for cooling is to stop the power supply to the heating element 46 and allow the cream to be cooled by air at ambient temperature. Therefore, the duration of step Em6 is practically dependent on the ambient temperature. For this purpose, a temperature sensor is advantageously positioned in the mixer 6, and more precisely, in the receiving device 5. To limit the number of temperature sensors, the same sensor measures the temperature of the heating element 46.

[0300] As shown in the embodiment, the temperature sensor measures the temperature of the heating element 46, and the same sensor is used again: this means that the end of step Em6 is determined by the temperature measured by the sensor, i.e., by the take-off temperature Tr' which is between 55°C and 60°C.

[0301] Once the temperature is reached, the actuation system 35 is stopped.

[0302] The cooling step Em6 typically lasts for at least 20 seconds, and preferably 40 seconds.

[0303] In a variant implementation, step Em6 may advantageously include, for example, a minimum stirring duration of about 40 seconds, followed by a supplementary stirring duration, which allows for ensuring good emulsification, and this supplementary stirring duration is only present before the removal temperature Tr' has been reached. Alternatively, stirring may continue for a certain duration even if the temperature is below the removal temperature Tr'.

[0304] It should be noted that, according to the embodiment not shown, the mixer 6 may include a cooling system for effectively cooling the cream and accelerating the process. For example, a cooling system equipped with a small fan may be provided, with or without supplemental cooling elements, the fan forcing air to circulate within the mixer 6, thus forcing cooling through strong convection.

[0305] Once the mixing method Em ends, the retrieval method Er can be initiated. The retrieval method Er will now be described.

[0306] Since the above steps take a certain amount of time (usually more than a minute), the user may not be near the mixer 6, but rather busy with their daily tasks (eating breakfast, listening to the radio, watching TV, buttering bread, getting dressed, ironing clothes, etc.). Therefore, it is important that the mixer 6 can keep the cream ready for use for the predetermined duration.

[0307] Therefore, in step Er1 (“Transfer step for storage”), the actuation system 35 is activated once to transfer the cream into the capsule (i.e., the first capsule 3 here) located on one side of the heating element 45. Once in a properly configured state, step Em6 has been stopped; this step is non-mandatory.

[0308] In step Er2 (“Prestress Holding Step”), the actuation system 35 is returned to the prestressed position, wherein the first actuation member 37 applies prestress to the first capsule 3 to bring the first capsule abutment against the diffuser plate 46.2. Then, in step Er3 (“Heating Step”), the heating element 46 is activated to maintain the cream at the removal temperature Tr'. Step Er2, for maintaining prestress, allows for better thermal conductivity, as in step Em2. Preferably, the stirring or movement of the actuation system 35 is performed periodically in step Er3 to ensure good emulsification, which can be partially disrupted by the presence of hot spots on the diffuser plate 46.2.

[0309] In a variant implementation, the removal method may replace step Er2 with step Er2' (“holding step in intermediate position”), in which the actuation system 35 is activated to position the capsules in an intermediate position, i.e., without forcing the first or second capsules 3,4, and specifically without forcing the first capsule 3 against the heating element 46. Surprisingly, this variant allows for better emulsification and avoids the use of cyclic stirring during the holding phase.

[0310] Step Er3 is performed during a predetermined waiting period. This period is less than 15 minutes to avoid supplying power to the heating element 46 for too long, and the duration is greater than 1 minute, preferably about 5 minutes, to allow for flexibility in morning time management for the user.

[0311] On the other hand, this means that after the movement of the actuation system 35 ends, the user has time between 1 minute and 15 minutes, preferably about 5 minutes (depending on the factory settings or user settings), to allow the cream to return to a suitable temperature.

[0312] When a user is ready to use the cream, they touch the touchscreen or press a button, which initiates step Er4 (“receiving the removal command”), during which the mixer 6 receives the removal command.

[0313] Then, in step Er5 (“the step of placing in the intermediate position”), the actuation system 35 is activated so that it is placed in the intermediate position.

[0314] With the actuation system 35 prestressed at the first actuation member 37, the first actuation member should cease its movement, moving the formulation to the second capsule 4. The actuation system 35 then stops at an intermediate position, corresponding to a position suitable for removing the receiving device 5. This position also corresponds to the starting position suitable for implementing the next manufacturing cycle of the described method. In fact, from the start of the drive motor 39, the second actuation member 38 is prepared to compress the second capsule 4 in step Em1.

[0315] In the implementation of the variant, the actuation system 35 is already in the intermediate position in step Er2' so that the heat preservation in step Er3 may require the actuation system 35 to perform reciprocating motion in order to position itself in the intermediate position suitable for implementing the next manufacturing cycle of the above method, that is, the second actuation member 38 is ready to compress the second capsule 4 in step Em1.

[0316] During the reciprocating motion of the actuation system 35, the cream present in the first capsule 3 is partially delivered into the second capsule.

[0317] Finally, in the final step Er6 (unlocking step), each mechanism activated in step Ei3 is placed in the insertion position. Similarly, step Er6 signifies the activation of the auxiliary motor 40.

[0318] The user then grasps the storage device 5 and removes it from its receiving portion 32. The user then presses the actuating surfaces 8.1, 9.1 to pivot the blades, thereby expelling the cream present in the first and second capsules 3,4 through the output channel 3.5 of the first capsule 3. Finally, the first or second capsule 3,4 is removed from the storage device 5, making the storage device ready for use again. In fact, no part of the mixer 6 (manufacturing equipment 2 or storage device) comes into contact with the formulation.

[0320] Ei1: The receiving steps for receiving the start command (implemented by the mixer and more precisely by the processor);

[0321] Ei2: Positioning steps of the actuation system (implemented by the mixer and more precisely by the processor that controls the drive motor);

[0329] Em6: Features a cooling step with stirring but without heating (cooling) until the removal temperature (implemented by a mixer, whose processor controls the drive motor);
