[0069] The device of the invention makes it possible to apply on the skin a cosmetic product specifically adapted to an application implementing a simultaneous mechanical action on the portion of the body of this application.

[0070] FIG. 1, according to an exemplary embodiment, the device of the invention is built on a basis (100) of elliptic contour. According to this embodiment, the aforementioned base is appreciably planar and made up of a rigid plastic, obtained, for example, by injection molding. It constitutes the contact face of the device of the invention, said contact face is turned towards the skin at the time of the use of the device of the invention. According to other exemplary embodiments, the shape the base is not planar and is curved according a simple or a double curvature, or its contour follows a more angular design, for example octagonal, or follows a circular form, without these examples being restrictive. The device of the invention comprises 2 rollers (101, 102), set up free to rotate around their respective axes (111, 112) extending in secant directions. According to this embodiment, each roller is assembled free to rotate in a cage (121, 122) said cage being elastically linked to the base by suspension arms (131, 132). The contact face of the device of the invention comprises one or more orifices (140) for dispensing of a cosmetic product. According to this embodiment, the contact face also includes a filling aperture (150), for the filling of a cosmetic product tank, said tank being in fluid communication with the aforementioned dispensing orifices (140). According to a specific embodiment, the aforementioned filling aperture (150) comprises a specific mechanical interface (not shown) to allow its filling only by means of containers comprising the adapted complementary mechanical interface, and thus limits the nature of the products likely to be introduced into the aforementioned tank. According to a non-restrictive example, the aforementioned tank comprises a diaphragm or a valve that only a nozzle of adapted conicity or diameter is capable to open.

[0071] The cosmetic product dispensing orifices (140) are placed so that, according to the recommended direction (190) of use of the device of the invention, the cosmetic product is delivered on the skin right before the passage of the rollers (101, 102) on the application zone. Thus, the product begins to act on the skin some time before the rollers come into contact with the treated zone, time as a function of the moving speed of the device of the invention. The position of the aforesaid orifices (140) is, according to this embodiment, appreciably aligned with the point of intersection of the rotation axes (111, 112) of the rollers. Thus, the cosmetic product is precisely dispensed on the zone subjected to the mechanical effect of the rollers. The aforementioned dispensing orifices (140) being placed on the contact face, the distributed product is protected from the washout during the use of the device under the shower. This position upstream of the product distribution orifice or orifices, combined with the rotation of the rollers according to secant axes, of which the intersection points in the moving direction of the device, makes it possible to ensure a substantially uniform distribution of the product, transported by the rollers during their rotation, over the entire width of the portion subjected to the mechanical action of the latter, although the device of the invention acts of a much wider surface, of about the width of a hand, than the devices of prior art.

[0072] According to this embodiment the shape of the rollers (101, 102) comprises a plurality of polygonal discs with rounded angles, juxtaposed according to the axis of rotation (111, 112) of the roller, and angularly shifted around this axis from one to the other. Each angle of the aforesaid polygonal discs constitutes a projecting notch with regard to the inscribed circle in the polygonal profile. The notched shape of the rollers, combined with their secant axes of rotation (111, 112), makes it possible to obtain, during the displacement of the device applied to the skin, a kneading effect, the skin located in front of the rollers, in the recommended direction (190) of progression, being compressed, whereas the skin located behind the rollers is stretched. Thus, the displacement of the device of the invention on the skin, driving the rollers in rotation, produces an effect that is similar to a palpate-roll massage. The rollers are made out of a material having a certain flexibility like an elastomer, for example out of silicone.

[0073] According to alternate embodiments, the dispensing of the cosmetic product by the orifices (140), is carried out either by gravity or by pumping means.

[0074] FIG. 6, in a case as in the other, according to a specific embodiment, the cosmetic product dispensing orifices are equipped with obturators making it possible to prevent the leak of the product by the aforementioned orifices when the device of the invention is not applied on the skin. Thus, according to an embodiment, the aforementioned obturators consist of flexible nipples (640), made of an elastomer, crimped in the dispensing orifices. FIG. 6A, each nipple (640) comprises one or more side slits (641), the edges of the said slits being jointed when the nipple (640) is not compressed, i.e. when the device of the invention is not applied on the skin. The viscosity of the cosmetic product is in generally high enough for the product not to flow through a slit (641) with jointing edges. FIG. 6B, in a situation of use, the pressure (690) exerted on the skin tends to crush the nipple (640) and to draw aside the edges of the slit (641), enabling the cosmetic product to flow through the slit. When the pressure (690) is released, the nipple (640) returns to its initial shape by elasticity, the edges of the slit (641) are again jointed and prevent the flow of the product,

[0075] According to another embodiment (not shown) the obturators of the dispensing orifices are valves, whose opening is triggered by the displacement, under the effect of the application pressure, of the suspension arms of the rollers. This last embodiment of the obturators makes it possible to contain a very fluid cosmetic product,

[0076] FIG. 2, the device of the invention comprises a handling face (200) in the shape of a cap covering the whole contour of the base. According to this embodiment, the cap is of semi-ellipsoidal shape. The dimensions of the cap constituting the handling face (200) are adapted to a catch in full hand of the device of the invention, with, according to this exemplary embodiment, a length, measured along the major axis of the ellipse, ranging between 120 mm and 170 mm, a width, according to the minor axis of the ellipse, ranging between 70 mm and 100 mm, and a height measured from the base to the top of the cap, ranging between 30 mm and 50 mm.

[0077] Thus, as shown on FIG. 4, the hand (490) of the user fits the shape of the handling face (200) of the massager device (400), in a configuration comparable with what the hand would take when making a caress on the region where the product is applied, leading to a natural gesture with a better control of the exerted pressure.

[0078] The contact face of the device of the invention thus covers over a surface of about 100 cm.sup.2, by applying a substantially uniform pressure on this surface, due to its method of prehension, while the devices of prior art, described for example in documents EP 1 472 953 and US 2005/020948, are applied on a surface of about 10 cm.sup.2 in light of their design and with regards to their method of prehension.

[0079] The handling face (200) is made of a rigid plastic, and, FIG. 9, according to an embodiment, advantageously comprises, locally or over its whole surface, one or more zones with a higher flexibility (211) or in relief (911) in order to ease and to secure gripping thereof. Advantageously, the zones in relief (911) are also comprised of a more flexible material.

[0080] Going back to FIG. 2, this figure shows the device of the invention in a free configuration i.e. before the application thereof on the skin. During the application of the device on the skin, the rollers (101, 102), mounted on the suspension arms thereof, are displaced towards the inside of the base in the direction of the cap (200) for handling until a skirt (210), mounted at the periphery on the contour of the base, comes into contact with the skin. According to this embodiment, the skirt (210) is made up of a more flexible material, for example of silicone.

[0081] FIG. 8, the skirt (210) thus mounted projects under the base (100) in such a way that it comes into contact with the skin at the time of the application of the device by exerting sufficient pressure. It thus participates mechanically and passively in the control of the pressure applied.

[0082] Going back to FIG. 2, according to this embodiment, a part (211) of the skirt is prolonged as flush on a portion of the cap, said portion falling under the thumb of the user during the use of the device of the invention. This part of the skirt thus provides a certain flexibility in the aforementioned cap so as to improve gripping.

[0083] FIG. 2 and FIG. 9, according to an embodiment, in which the cosmetic product is dispensed by the implementation of pumping means, a knob (240) slightly projects from the cap, for example in an area located under the thumb during the use of the device of the invention. The aforementioned knob (240) actuates the pumping means, making it possible to dispense the cosmetic product contained in the tank.

[0084] When free from pressure, the rollers (101, 102) are projecting under the base and the skirt (210). At the time of the application of the product on the skin, said rollers are applied to the skin and the pressure of the hand on the cap making the handling face (200), makes it possible to deform the suspension arms and to lift up the rollers in the base, until the skirt (210) comes into contact with the skin. Thus, the applied pressure by the rollers on the skin, is set precisely by the way of the stiffness of the suspension arms, and their relative position with regard to the contact face and the skirt (210), according to this embodiment. The aforementioned pressure remains thus appreciably constant as long as that the skirt (210) remains in contact with the skin. Each roller being suspended independently, the device adapts itself to the shapeliness of the region, whereon, the device is applied, and the contact of the contact face with the skin, via the skirt ensures a perfect positioning of the rollers with regard to the application region, and during the displacement of the device, thus ensuring an optimal effectiveness of the mechanical effect of the aforesaid rollers on the skin. The shape and the constitution of the skirt (210) are designed so that it glides easily on the wet skin or on a skin on which a cosmetic product was applied. Thus, the user of the device of the invention easily keeps an adapted pressure while moving the device on the application region, by keeping the skirt (210) in contact with the skin, without experiencing an unpleasant rubbing of the aforesaid skirt on the skin. According to a particular embodiment, the inside surface (212) of the skirt coming into contact with the skin, comprises dissymmetrical reliefs (not shown) which make the gliding of the aforesaid skirt on the skin, easier in the appropriate massage direction (190, FIG. 1), and more resistant in another direction of use. Thus, the user instinctively uses the device in the right direction.

[0085] FIG. 3, the base (100) and the cap making the handling face (200) are assembled by clipping, the skirt (210) being inserted between the two during the assembly. This embodiment provides an easy assembly of the device of the invention in the framework of a mass production. The rigid base (100) is used as a support for modules conferring on the device of the invention additional functionalities, said modules being hidden and protected by the cap making the handling face (200). Thus, the tank (340) of cosmetic product is fixed to the aforementioned base. According to this embodiment, the aforementioned tank (340) comprises a flexible membrane (341), projecting, after assembly, on the surface of the cap, said membrane constituting the actuation knob for the pumping means. According to this purely mechanical embodiment, a pressure exerted on the aforementioned membrane modifies the interior volume of the tank (340) and produces the pumping effect for expelling the product contained in the tank through the dedicated orifices. This embodiment of the pump also makes it possible to dispense the appropriate quantity of product, the expelled volume being defined by the projecting volume of the membrane (341). Typically, the tank has a capacity between 5 ml and 10 ml of product.

[0086] According to another embodiment, the pump is an electric pump, and the knob, on the gripping face drives the actuation of the pump. Advantageously, the start of the electric pump is conditioned with the closing of a contact actuated by the suspension arms of the rollers, so that the cosmetic product can be dispensed only if the aforementioned rollers are applied to the skin.

[0087] According to a specific embodiment (not shown), the tank is a removable tank. In this case, the opening (311) of the cap accommodating the prolongation (211) of the skirt, is used to introduce said removable tank. In such an embodiment, the skirt does not include such a prolongation (211) towards the cap, this part being integrated into the removable tank.

[0088] According to an embodiment, the base (100) comprises housings (391, 392) receiving electronic means, making it possible to measure and to analyze the product application conditions and the mechanical effect generated by the rollers, as well as batteries for supplying these means with energy.

[0089] FIG. 7, as a non-limiting example, the aforementioned electronic means comprise individually or in combination: [0090] a clock for measuring the duration of the massage and its date of performance; [0091] an accelerometer (711) for assessing the direction and the velocity of the device during the massage; [0092] a strain gauge (712) or a position sensor of the rollers suspension arms, to determine the pressure exerted during the massage; [0093] a temperature gauge (713), for example an infrared sensor, for measuring the temperature of the skin; and [0094] means suitable for reading an identification code of the cosmetic product contained in the tank.

[0095] In an embodiment of the device of the invention, where the tank is a removable interchangeable tank, said tank comprises means suitable to cooperate with the means for reading the identification of the product.

[0096] In an embodiment of the device of the invention comprising a fixed tank and a filling aperture, said aperture is equipped with means cooperating with complementary means carried by the container used for the filling of the tank, so as to identify the product.

[0097] In both of these embodiments, the means of identification, carried by the container of the refill of product, comprise, according to nonrestrictive examples: [0098] a microchip, or [0099] a zone comprising electrically conductive and electrically isolating areas, laid out according to a specific pattern, or [0100] pins or wedges laid out according to a specific pattern.

[0101] The reading means carried by the massager device comprise: [0102] means for reading the microchip of the refill, or [0103] a set of electrical contacts interacting with the conductive and isolated areas of the refill, or [0104] knobs actuated by the pins or wedges of the refill.

[0105] An electronic module (790) comprising an input port (795) and an outlet port (796) makes it possible to collect the data issued by ail the sensors of the device of the invention and to combine them for their analysis implementing a microprogram (792) recorded in the electronic module.

[0106] The surface of the base and the volume available under the handling cap of the device of the invention make it possible to easily integrate all of these means.

[0107] FIGS. 8 and 9, according to an embodiment, the device of the invention, in its version known as electronic, advantageously comprises a sensory means of communication with the user. As examples, the aforementioned sensory means comprise, individually or in combination: [0108] a visual means, like one or more colored light emitting diodes (950) installed on the cap, or a liquid crystal display; [0109] sound emitting means, straight or modulated; [0110] tactile means (850), like a vibrator, for example fixed on the cap inside the latter.

[0111] The activation of said sensory means is controlled by the electronic module.

[0112] The sensors (711, 712, 713, 714), the sensory means (950, 850) of communication, the electronic module (790), the battery (710) and all connections between these elements are protected with respect to water jets and an immersion up to 1 meter in depth, and are IP 67 compliant according to IEC 60529 standard. Thus, the device of the invention, in its electronic version, can be used under the shower or in the bath. The electronic components are also selected and protected so that they can withstand, under operation and without any damage, an exposure to a wet temperature of 70 C., for at least 5 minutes.

[0113] According to this electronic version of the device of the invention, the electronic module (790) comprises, in the memory means (791), the ranges of values relating to the parameters characterizing the product application conditions and mechanical action on the skin, and which are assessed by the processing of the data issued from the various sensors. For example, if to be effective the application of the product must be carried out during displacements from bottom to top of the device on the treated region, with a given minimal pressure and a given maximum speed, the electronic module detects the beginning of the application by the simultaneous change of the values of the pressure on the rollers and of the displacement of the device. The speed and the direction of displacement are assessed by analyzing the information issued from the accelerometer. Alternatively or in a complementary way, information concerning the displacement of the device is obtained by a sensor (714) measuring the rotation of the rollers. As long as the parameters related to the speed, the pressure and the direction of application are each kept inside a permissible value range recorded in the memory means (791) of the electronic module, a LED (950), located for example in a visible area on the handling face of the massager device, lights up in green. If the pressure drops or if the displacement speed becomes too important, or too low, then the LED lights up in red, or, if the sensory means of communication comprise a vibrator (850), the latter vibrates. Thus, the user is informed instantaneously that he is drifting from the ideal conditions of application of the product and corrects itself his gesture. For example, if the effectiveness is optimal when repeating several times, for example 3 times, a passage of the device on the same part of the body, according to strokes of a length ranging between 30 cm and 50 cm, from bottom to top in the standing position, and with a speed ranging between 5 cm.Math.s.sup.1 and 10 cm.Math.s.sup.1, the 3 strokes being made in a 45 seconds maximum time lapse. According to an embodiment, the device of the invention includes an init button (960) on the handling face. Before carrying out the strokes on a given part of the body, the user pushes the init button thus starting a timing of the 45 seconds open time by the clock, and the lighting of an orange LED, informing the user that the system awaits an action. The orange LED blinks after a 30 seconds time if the 3 strokes were not carried out. The microprogram of the electronic module interprets the data from the sensors in order to detect the performance of each stroke. The detection of a massage stroke is, for example, carried out by the detection of the application of the pressure and the displacement of the device followed by the detection of a stop of the displacement and a release of the pressure. The microprogram counts the strokes and lights a green LED if the three strokes were carried out according to the appropriate time lapse and the planned massage conditions.

[0114] Advantageously, the electronic module comprises in memory several ranges of values corresponding to the various phases of a care program, implementing various cosmetic products according to its various phases. The nature of the product contained in the tank being detected, the range of value used for the monitoring of the massage conditions is selected accordingly by the microprogram.

[0115] According to a simplified embodiment of the electronic version of the device of the invention, the LED (950) lights up in green when the adapted applied pressure is reached, and shuts off if this pressure leaves the recommended range.

[0116] Advantageously, the LED (950) is also used to inform the user about the state of the battery.

[0117] Thus, the implementation of sensors and of an electronic module brings a technical assistance about the adequate use of the device and in the performance of the application of a cosmetic product under optimal conditions.

[0118] FIG. 5, according to a specific embodiment, the electronic module of the device of the invention (400) includes means of radio communication (793), suitable to set up a short distance communication with one or more connected objects, for example with a smartphone (500), according to a wireless personal area network, or WPAN. As nonrestrictive examples, the WPAN is established according to a BLUETOOTH protocol (registered trademark of Bluetooth Sig, Inc., preferentially Bluetooth 4.0 or low energy, for a lesser power consumption, or according to the ZIGBEE protocol. The range of said short distance radio signals lies between 5 meters and 10 meters and thus allows the data exchange between the device (400) of the invention and the connected object, whereas the user is under the shower and that the aforementioned connected object stays in a dry place.

[0119] As nonrestrictive examples, the connected object is a smartphone, a tablet PC, a laptop computer, the computer of a house automation system, a connected watch or a connected wristband, or a simplified connected device, specifically dedicated to the device of the invention. The connected object comprises memory means, a processor, a display and an input device, like a touch screen or a keyboard.

[0120] The connected object, for example a smartphone (500), exchanges data with the electronic module once paired with it, thus creating a WPAN. According to an embodiment, the smartphone (500) is set as master on the network thus created, the electronic module of the device (400) of the invention being slave.

[0121] According to an advantageous embodiment, the aforementioned connected object is connected to Internet (550) by a connection separate from the one that connects it with the device (400) of the invention. According to the nature of the connected object, this connection with Internet is a wireless connection, for example via a WiFi connection or via a cell phone network, or a wire connection.

[0122] According to this embodiment of the device of the invention, known as the connected version, the technical functions for the monitoring of the conditions of use of said device are shared between the microprogram of the electronic module and a software application, setup in the smartphone (500), or in a wider sense, in the connected object.

[0123] According to a first aspect, the connected version of the device of the invention enhances the possibilities of interpretation of the data compared to the electronic version, by offering extended calculation capabilities and more memory, and by offering the opportunity of a post treatment of the data, after the performance of the application of the product, notably in order to take these data into account in a cosmetic care program, the data in the course of the application remaining treated by the microprogram. For this purpose, the parameters characterizing the application conditions are stored and timestamped in the memory of the electronic module of the massager device (400) of the invention, and uploaded to the smartphone (500) when both are paired. Thus, the monitoring of the application conditions is performed even if the smartphone (500) was shut down or was out of range at the time of application of the product on the skin.

[0124] According to a second aspect, the connected version of the device of the invention, opens the possibility to update of the microprogram of the electronic module. For this purpose, according to an update proceeding, the smartphone (500) connects to an application server (591) via Internet (550), downloads an update of the microprogram, and when paired with the electronic module, transfers the updated microprogram in the memory of the electronic module. According to another embodiment, the information downloaded from the smartphone (500) towards the electronic module of the device (400) of the invention is limited to the admissible ranges of values of the application parameter, corresponding to the conditions adapted to the phase of the cosmetic care program in progress.

[0125] According to a third aspect, the device of the invention, in its connected version, makes it possible to build a cosmetic care program adapted to the result aimed by the user. For this purpose, the smartphone (500) comprises a software expert system, capable of building the personalized cosmetic care program, according to the information indicated by the user in the aforementioned application, such as his age, his weight, his size, his body measurements and the body regions where he aims an improvement of the skin aspect. Starting from these data, the expert system proposes a cosmetic care program, in terms of the number of sessions and the conditions of each session: the application region, the number of strokes . . . but also defines the corresponding parameters and the nature of the cosmetic products to apply at said sessions. The data exchange between the device (400) of the invention and the smartphone (500) makes it possible to ensure the monitoring of the cosmetic care program, but also to guide and encourage the user, by the display of messages on the screen of the smartphone (500).

[0126] According to a fourth aspect, the smartphone is connected with other connected objects via the WPAN. Said connected objects are, for instance, related to lifestyle and to well-being, for example, a connected scale (510), a connected fitness apparatus, or a connected wristband measuring the physical activity. The expert system of the smartphone recommends an evolutionary cosmetic care program adapted to the lifestyle of the user and its follow-up of the program, and displays encouragement messages prompting him to persevere in the aforementioned program.

[0127] According to a fifth aspect, the smartphone (500) is connected via Internet (550) to a social network server (592) and connects the user to other users of the device, also connected via their smartphones (501), in order to share their experience and their results, thus creating a community of users, supporting each other in the observance of the proposed cosmetic care programs that are proposed to them.

[0128] Advantageously, the application installed on the smartphone (500) allows the user to order on line the cosmetic products adapted to its program, so that they are timely delivered in accordance with its needs in the course of the aforesaid cosmetic care program.

[0129] FIG. 10, thus, according to an exemplary implementation of the method of the invention, during a step of comparing (1040) the microprogram comprised in the electronic module compares the ranges of permissible values (1020) of a parameter concerning the application of the cosmetic product by means of the device of the invention and recorded in the memory means of the electronic module, with the value of this parameter (1030) measured by means of the at least one of the sensors of the device of the invention or using a combination of the data from the various sensors. If during a test step (1045) the measured parameter is within the permissible range of values, the microprogram informs (1050) the user using sensory means, LED or vibrator for example, arranged on the device of the invention, according to a certain configuration of these sensory means, for example by lighting a LED in green, or by not vibrating the vibrator. If the parameter measured is not within the permissible range, then the microprogram informs the user (1060) via the sensory means of the device of the invention by placing the latter in a suitable configuration, for example, by lighting the LED in red or by vibrating the vibrator. According to embodiments, the permissible ranges of parameters are initially listed in the memory means of the electronic module, or the latter are obtained by a downloading (1010) of said ranges, for example, from a connected object paired with said electronic module. According to an improved embodiment, the values of the parameter or parameters measured during the use of the device of the invention are also sent (1070) by the microprogram of the electronic module to the paired connected device.
