(20) In particular, the manufacturing apparatus 2 comprises first and second capsules 3, 4, also called pods or packaging units, respectively containing a predetermined amount of a first formulation and a predetermined amount of a second formulation, a receiving device 5 configured to receive the first and second capsules 3, 4, and a mixing machine 6 configured to receive the receiving device 5 equipped with the first and second capsules 3, 4, and to mix the first and second formulations contained in the first and second capsules 3, 4 so as to obtain a cosmetic product. Advantageously, the mixing machine 6 is configured to mix the first and second formulations inside the receiving device 5, and preferably inside the first and second capsules 3, 4.

(21) Advantageously, the first formulation is a first phase of the cosmetic product to manufacture, such as a fatty phase of the cosmetic product, whereas the second formulation is a second phase of the cosmetic product, such as an aqueous phase of the cosmetic product. For example, the fatty phase may constitute the base of the cosmetic product to manufacture, and the aqueous phase may comprise active elements and thus constitute a complex of active ingredients of the cosmetic product to manufacture.

(22) As shown more particularly in FIGS. 2 to 6, the first and second capsules 3, 4 are distinct from each other, and are configured to be fluidly connected to each other. Furthermore, each of the first and second capsules 3, 4 is advantageously intended for a single use.

(23) The first capsule 3 includes a first deformable compartment 3.1 containing the first formulation, a first connection portion 3.2 and a first connecting passage 3.3 configured to fluidly connect the first deformable compartment 3.1 and the first connection portion 3.2. Advantageously, the first connecting passage 3.3 is formed by a first connecting channel, and the first connection portion 3.2 extends substantially perpendicular with respect to the first connecting passage 3.3. More particularly, the first connection portion 3.2 includes a male connection fitting 3.4, for example cylindrical shaped, fluidly connected to the first connecting passage 3.3.

(24) According to the embodiment represented in the figures, the first deformable compartment 3.1 includes a first frangible peripheral area 3.10 having one or several frangible portion(s), also called weakening portions, configured to break up when a sufficient mechanical pressure is exerted on the first deformable compartment 3.1.

(25) Advantageously, the first capsule 3 also includes a first buffer area 3.11 extending at least partially around the first peripheral area 3.10 of the first deformable compartment 3.1, and the frangible portion(s) of the first deformable compartment 3.1 are located such that, when the frangible portion(s) are broken, the content of the first deformable compartment 3.1 can flow into the first buffer area 3.11.

(26) More particularly, the first buffer area 3.11 is configured to fluidly connect the first deformable compartment 3.1 and the first connecting passage 3.3 when the frangible portion(s) of the first deformable compartment 3.1 are broken. Advantageously, before the breakage of the frangible portion(s) of the first deformable compartment 3.1, the two walls delimiting the first buffer area 3.11 are in contact with each other such that the volume of the first buffer area 3.11 is then substantially zero. After the breakage of the frangible portion(s) of the first deformable compartment 3.1, the flow of the content of the first deformable compartment 3.1 into the first buffer area 3.11 induces a deviation of the two walls delimiting the first buffer area 3.11, and therefore an increase of the volume of the first buffer area 3.11.

(27) The first capsule 3 further includes an outlet passage 3.5, such as an outlet channel, which is fluidly connected to the first connecting passage 3.3, and which is provided with an outlet orifice 3.6.

(29) The second capsule 4 includes a second deformable compartment 4.1 containing the second formulation, a second connection portion 4.2 configured to be connected to the first connection portion 4.1, and a second connecting passage 4.3 configured to fluidly connect the second deformable compartment 4.1 and the second connection portion 4.2. Advantageously, the second connecting passage 4.3 is formed by a second connecting channel, and the second connection portion 4.2 extends substantially perpendicular with respect to the second connecting passage 4.3. More particularly, the second connection portion 4.2 includes a female connection fitting 4.4, for example cylindrical shaped, fluidly connected to the second connecting passage 4.3 and configured to tightly receive the male connection fitting 3.4.

(30) According to the embodiment represented in the figures, the second deformable compartment 4.1 includes a second frangible peripheral area 4.10 having one or several frangible portion(s), also called weakening portions, configured to break up when a sufficient mechanical pressure is exerted on the second deformable compartment 4.1.

(31) Advantageously, the second capsule 4 also includes a second buffer area 4.11 extending at least partially around the second peripheral area 4.10 of the second deformable compartment 4.1, and the frangible portion(s) of the second deformable compartment 4.1 are located such that, when the frangible portion(s) are broken, the content of the second deformable compartment 4.1 can flow into the second buffer area 4.11.

(32) More particularly, the second buffer area 4.11 is configured to fluidly connect the second deformable compartment 4.1 and the second connecting passage 4.3 when the frangible portion(s) of the second deformable compartment 4.1 are broken. Advantageously, before the breakage of the frangible portion(s) of the second deformable compartment 4.1, the two walls delimiting the second buffer area 4.11 are in contact with each other such that the volume of the second buffer area 4.11 is then substantially zero.

(33) According to the embodiment represented in FIGS. 1 to 22, the second capsule 4 includes a thermoformed shell 4.5 and a sealing sheet 4.6 covering the thermoformed shell 4.5. Advantageously, the thermoformed shell 4.5 and the sealing sheet 4.6 of the second capsule 4 delimit the second deformable compartment 4.1 and the second connecting passage 4.3.

(34) Advantageously and for reasons set out hereinafter, each of the first and second capsules 3, 4 is configured to contain the entirety or substantially the entirety of a mixture formed by the predetermined amount of the first formulation and the predetermined amount of the second formulation.

(35) As shown more particularly in FIGS. 7 to 14, the receiving device 5 is capable of occupying an open position in which the first and second capsules 3, 4 can be introduced into the receiving device 5, and a closed position in which the receiving device 5 is capable of holding the first and second capsules 3, 4 in position.

(36) More particularly, the receiving device 5 includes a receiving case 7 configured to receive and house at least partially the first and second capsules 3, 4. In particular, the receiving case 7 includes a first protecting shell 8 and a second protecting shell 9 hingedly mounted relative to each other about a hinge axis 10 and between a first position (see FIG. 8) corresponding to an open position of the receiving device 5 and a second position (see FIG. 7) corresponding to a closed position of the receiving device 5.

(37) The receiving device 5 further includes a first support portion 11 and a second support portion 12 disposed in the receiving case 7. The first and second support portions 11, 12 respectively include a first receiving location 13 configured to receive the first capsule 3 and a second receiving location 14 configured to receive the second capsule 4. Advantageously, the first receiving location 13 includes a first receiving groove 15 configured to receive a peripheral portion of the first capsule 3, and the second receiving location 14 includes a second receiving groove (not shown in the figures) configured to receive a peripheral portion of the second capsule 4.

(38) According to the embodiment represented in FIGS. 1 to 22, the first and second support portions 11, 12 are hinged relative to each other about the hinge axis 10 and between a receiving position (see FIGS. 8 and 13) in which the first and second support portions 11, 12 are brought away from each other and the first and second capsules 3, 4 can be received respectively in the first and second receiving locations 13, 14, and a connection position (see FIG. 12) in which the first and second support portions 11, 12 are brought close to each other and the first and second capsules 3, 4 can be connected to each other. For example, the first and second support portions 11, 12 may have an angle of inclination comprised between 5 and 20°, and for example of about 10°, when they are in the receiving position, and be substantially parallel to each other when they are in the connection position.

(39) Advantageously, the first and second support portions 11, 12 are configured to be displaced in the connection position when the receiving device 5 is displaced into the closed position, and therefore to fluidly connect the first and second connection portions 3.2, 4.2 when the receiving device 5 is displaced into the closed position.

(65) In addition, the mixing machine 6 includes a drive motor 39 mounted on the support 31. The drive motor 39 is configured to make the actuation portion 35 pivot about the pivot axis 36 and within a predetermined angular range.

(66) According to the embodiment represented in FIGS. 1 to 22, the mixing machine 6 also includes a drive wheel 41 rotatably secured to an output shaft of the drive motor 39 and configured to be driven in rotation about its wheel axis and in a direction of rotation by the drive motor 39. The drive wheel 41 is equipped with a drive element 42, such as a drive pin, which is eccentric with respect to the wheel axis, and which is received in a receiving aperture 43 provided on the actuation portion 35. Advantageously, the receiving aperture 43 is elongate and extends in a direction of extension substantially parallel to the pivot axis 36. Such a configuration of the mixing machine 6 allows obtaining an alternating movement of the actuation portion 35 by making the drive motor 39 rotate always in the same direction of rotation, so that it is not necessary to resort to an expensive system for controlling the drive motor 39.

(67) According to a variant of the invention, the mixing machine 6 may be configured such that a rotation of the drive motor 39 in a first direction of rotation causes a pivoting of the actuation portion 35 in a first pivot direction and a rotation of the drive motor 39 in a second direction of rotation, opposite to the first direction of rotation, causes a pivoting of the actuation portion 35 in a second pivot direction, opposite to the first pivot direction.

(68) According to the embodiment represented in FIGS. 1 to 22, the receiving device 6 includes (see FIG. 20) two primary guide elements 44, such as guide grooves, configured to cooperate respectively with secondary guide elements 45, such as guide pins or guide legs, provided on the mixing machine 6, when the receiving device 5 is received in the mixing machine 6. The primary guide elements 44 may be provided for example on the first support portion 11, and the secondary guide elements 45 may be provided for example on the support 31. The presence of such guide elements allows facilitating the positioning of the receiving device 5 in the receiving housing 32.

(69) The manufacturing apparatus 2 further includes a heating element 46 configured to heat up at least the first capsule 3 when the receiving device 5 equipped with the first and second capsules 3, 4 is received in the mixing machine 6. For example, the heating element 46 may comprise a heating resistor element 46.1 and a heating plate 46.2 adjacent to the heating resistor element 46.1.

(70) According to an embodiment represented in the figures, the heating element 46 is disposed in the receiving device 5, and is advantageously mounted on the first support portion 11 so as to extend between the first and second capsules 3, 4 when these are received in the receiving device 5. Preferably, the heating element 46 is arranged so as to extend proximate to the first deformable compartment 3.1, and for example in contact with the first deformable compartment 3.1. However, according to another embodiment of the invention, the heating element 46 may be disposed in the mixing machine 6 and be configured to extend between the first and second capsules 3, 4 when the receiving device 5 equipped with the first and second capsules 3, 4 is received in the mixing machine 6.

(71) According to an embodiment of the invention, the mixing machine 6 also includes an electric power supply source (not represented in the figures) configured to electrically power the mixing machine 6, and in particular the drive motor 39. For example, the electric power supply source may include at least one rechargeable battery.

(72) Advantageously, when the heating element 46 is disposed in the receiving device 5, the electric power supply source is also configured to electrically power the receiving device 5, and in particular the heating element 46, when the receiving device 5 is received in the mixing machine 6. To this end, the mixing machine 6 includes a first electrical connector (not represented in the figures), and the receiving device 5 includes a second electrical connector (not represented in the figures) configured to be connected to the first electrical connector when the receiving device 5 is received in the mixing machine 6, so that the mixing machine 6 is capable of electrically powering the receiving device 5.

(73) The mixing machine 6 further includes a controller, for example provided with a microcontroller, configured to control the operation of the drive motor 39 and of the heating element 46.

(74) The manufacturing apparatus 2 further includes a closure element 47 configured to automatically close the outlet passage 3.5 of the first capsule 3 when the receiving device 5, equipped with the first and second capsules 3, 4, is received in the mixing machine 6, and to automatically clear the outlet passage 3.5 when the receiving device 5 equipped with the first and second capsules 3, 4 is removed out of the mixing machine 6. Advantageously, the closure element 47 is configured to exert a pressure on a wall of the outlet passage 3.5 so as to close the latter.

(75) For example, the closure element 47 may be movably mounted on the first protecting shell 8 between a closing position (see FIGS. 14 and 15) in which the closure element 47 is capable of closing the outlet passage 3.5, and a clearance position (see FIG. 12) in which the closure element 47 is capable of clearing the outlet passage 3.5, and the mixing machine 6 may include for example a displacement element 48 configured to displace the closure element 47 into the closing position when the receiving device 5 is inserted into the mixing machine 6.

(76) According to the embodiment represented in FIGS. 1 to 22, the displacement element 48 is fixedly mounted with respect to the support 31 and includes a displacement ramp 49 (see FIG. 14) configured to cooperate with the closure element 47 and displace the latter toward the clearance position.

(77) Advantageously, the manufacturing apparatus 2 includes a biasing member (not represented in the figures) configured to bias the closure element 47 toward the clearance position. These arrangements ensure an automatic displacement of the closure element 47 into the clearance position as soon as the receiving device 5 is removed out of the mixing machine 6.

(78) According to the embodiment represented in FIGS. 1 to 22, the manufacturing apparatus 2 further includes a counter-support element 51, such as a rib or a counter-support leg, configured to bear against the first capsule 3 and to be disposed opposite the closure element 47 when the receiving device 5 equipped with the first and second capsules 3, 4 is received in the mixing machine 6. Advantageously, the counter-support element 51 is provided on the receiving device 5, and for example on the second protecting shell 9. The presence of such a counter-support element ensures an optimum pinch of the outlet passage 3.5 when the receiving device 5 is received in the mixing machine 6.

(79) A method for manufacturing a cosmetic product using the manufacturing apparatus 2 will now be described. In particular, such a manufacturing method comprises the following steps of: providing the manufacturing apparatus 2, displacing the first and second protecting shells 8, 9 into the first position, displacing the first and second support portions 11, 12 into the receiving position, inserting the first and second capsules 3, 4 respectively into the first and second receiving locations 13, 14, displacing the first and second protecting shells 8, 9 into the second position so as to displace the first and second support portions 11, 12 into the connection position, and therefore so as to connect the first and second connection portions 3.2, 4.2, inserting the receiving device 5 equipped with the first and second capsules 3, 4 into the receiving housing 32 of the mixing machine 6, automatically displacing the closure element 47 into the closing position so as to automatically close the outlet passage 3.5 of the first capsule 3, heating up the first deformable compartment 3.1 and the first formulation contained therein, and mixing the first and second formulations inside the first and second capsules 3, 4 so as to obtain the cosmetic product.

(80) More particularly, the mixing step includes the following steps of: making the actuation portion 35 pivot in the first pivot direction so that the first actuation member 37 exerts a pressing force on the first bearing element 19 and displaces the latter into the active position; such a displacement of the first bearing element 19 inducing an overpressure at the level of the first frangible peripheral area 3.10 of the first deformable compartment 3.1 and therefore a breakage of the respective frangible portion(s), then a flow of the first formulation, contained in the first deformable compartment 3.1, into the second buffer area 4.11 via the first connecting passage 3.3 and the second connecting passage 4.3; such a flow of the first formulation inducing an overpressure at the level of the second frangible peripheral area 4.10 of the second deformable compartment 4.1, and therefore a breakage of the respective frangible portion(s) and a penetration of the first formulation into the second deformable compartment 4.1, making the actuation portion 35 pivot in the second pivot direction so that the second actuation member 38 exerts a pressing force on the second bearing element 21, so as to displace the latter into the active position and induce a flow of the mixture of the first and second formulations contained in the second deformable compartment 4.1 into the first deformable compartment 3.1, and making the actuation portion 35 pivot successively in the first pivot direction and in the second pivot direction, and repeat such a step several times, and for example 2 to 15 times, advantageously 5 to 10 times, so as to make the mixture of the first and second formulations pass successively into the first deformable compartment 3.1 and into the second deformable compartment 4.1, in order to obtain a homogeneous mixture of the first and second formulations.

(81) The manufacturing method further comprises the following steps of: removing the receiving device 5 out of mixing machine 6, automatically displacing the closure element 47 into the clearance position so as to automatically clear the outlet passage 3.5 of the first capsule 3, manually exerting a mechanical pressure on the first and second bearing elements 19, 21 so as to expel the manufactured cosmetic product out of the first and second capsules 3, 4, and retrieving, for example on the fingers of a user, the manufactured cosmetic product.

(82) FIGS. 23 and 24 represent a manufacturing apparatus 2 according to a second embodiment of the invention which differs from that represented in FIGS. 1 to 22 in particular in that the actuation portion 35 is mounted movable in translation relative to the support 31 and is capable of occupying a first position in which the first actuation member 37 can exert a pressing force on the first bearing element 19 and a second position in which the second actuation member 38 can exert a pressing force on the second bearing element 21, and in that the mixing machine 6 includes a drive cam 52 rotatably secured to the drive motor 39 and configured to displace the actuation portion 35 toward the first position, and a biasing element 53, such as a helical spring, configured to bias the actuation portion 35 toward the second position.

(83) It goes without saying that the invention is not limited to the sole embodiments of this manufacturing apparatus, described hereinabove as examples, but it comprises, on the contrary, all variants thereof. Thus, in particular, the first and second actuation members may be separate and distinct from each other.
