Assembly of frontal faces defines a tapered envelope. The bases are arranged along radial assembly lines (L1-L4). Receiving spaces (34-12, 34-23, 34-34, 34-41) are unequipped with reliefs and are extended angularly above 20 degree, around the axis.

Description

The invention relates to a massage member for kneading-twisting of human skin, a device and an assembly comprising such a massage member, and a method using such a massage member. The kneading-twisting is a massage maneuver that combines vigorous pinching and kneading, the kneading consisting of strongly palpating the muscles or the different layers of the skin, depending on the desired effect. The kneading-twisting is usually done with the fingers and relaxes the muscles and strengthen their tone. To simulate the action of the fingers, there is known, for example from EP 0 135 946, a massage device comprising a plurality of connecting rods mounted on the crank pinions driven in rotation. The movement of the crankshafts gives the ends of the rods a back and forth movement supposed to reproduce the movement of the fingers of a hand during a kneading. Such a device is technically complex and does not allow a large-scale torsion.

Furthermore, there are known electrical devices for rotating massage and gumming trays provided with fins, as described for example in US 3,906,940 or FR 2 072 609. To perform a homogeneous exfoliation, the tray is applied flat against the skin and rotated so that the friction of the fins cleans the skin. This action on the skin is different from that of a kneading-twisting maneuver, since, in the latter case, the main objective is not to rub on the skin, but on the contrary to drag the latter so as to folds. There is therefore a need for a kneading-twisting device capable of effectively pinching the skin and which is technically simple and of a modest cost. The object of the invention is to satisfy this need by providing a massage member for kneading-twisting of human skin, this massage member comprising: a support provided to be rotated about an axis X; a plurality of kneading reliefs, each of the kneading reliefs extending, preferably substantially axially, from a base rigidly secured to the support to a front face, all of said end faces delimiting a flared envelope, preferably substantially X-axis, the bases of the kneading reliefs being arranged along at least two substantially radial positioning lines, the angular spacing between two adjacent positioning lines and the shape of the kneading reliefs being determined to provide, between said two lines of adjacent positioning, a skin-ply-receiving space devoid of kneading reliefs and extending angularly over more than 20 degrees, preferably more than 30 degrees, or even more than 40 degrees, preferably greater than 50 degrees, about said axis X. As will be seen in more detail in the following description, a rotation of the massage member is In the invention around the X axis while the front faces of the kneading reliefs are in contact with the skin allows the kneading reliefs to hang on the surface of the skin, and thus wrinkle. The flared envelope and the reception spaces between the various lines of kneading reliefs receive the folds thus formed, which prevents these folds from pushing the body away from the skin. This results in remarkable efficiency to knead the skin in torsion.

Positioning Lines Positioning lines extend substantially radially from the X axis. They may be rectilinear or curved, for example along an arc of a circle. At least one positioning line, and even all the positioning lines, may extend in a normal plane. A single kneading relief, substantially elongated, may be arranged on a positioning line. Alternatively, several kneading reliefs, which may be identical or different, may be arranged along the same positioning line. The number of kneading reliefs along a positioning line can be identical regardless of the positioning line, or be different depending on the positioning line considered. The number of positioning lines is preferably greater than or equal to 3 and / or less than or equal to 8, or even less than or equal to 6. The presence of four positioning lines is particularly well suited. The positioning lines are preferably distributed substantially equiangularly about the X axis.

Kneading reliefs The shape of the kneading reliefs is not limiting provided that their front faces belong to a virtual envelope surface of generally flared shape (flared envelope) and that their widths are limited to allow said reception spaces to be made. Unlike fins used to erase the skin, the kneading reliefs must not sag when the massage member according to the invention is pressed against the skin. They must therefore have an intrinsic rigidity allowing them to substantially retain their shape in use, that is to say under normal pressure during a massage operation. In an exemplary implementation, under the action of the thumb of the user, the front face of a kneading relief does not tilt more than 45 °, preferably more than 30 °, compared to support. For this purpose, the kneading reliefs may be made of a relatively rigid plastic, for example of the PE, PP, ABS, POM or PA type. To avoid, however, too harsh contact with the skin, the front face of the kneading reliefs, or even the entire outer surface of the kneading reliefs, or even the support, and in particular the portion of the support that can come into contact with the skin on contact with the skin. use, may be coated with a softer material, for example in the form of an elastic film, preferably less than one millimeter thick. The kneading reliefs may also be made of a flexible plastic material of the elastomer type, SEBS, HYTREL or silicone, for example. If necessary, additional stiffening means may be provided, for example stiffening ribs or a core of a more rigid material. To ensure the rigidity of a kneading relief, the greatest width of its base, measured perpendicular to the corresponding positioning line, is preferably greater than or equal to 3 mm, more preferably greater than or equal to 5 mm and / or less than or equal to 15 mm, or even less than 10 mm. A width of 7 mm is well suited. The maximum height of a kneading relief may be greater than 5 mm, even greater than 7 mm, or even greater than 9 mm and / or less than 15 mm, 13 mm or even 12 mm. A maximum height of 10 mm is well suited.

To further reinforce the rigidity of the kneading reliefs, it is preferable that these knitting reliefs are integral with the support. The method of manufacturing the massage device may further be advantageously simplified. Preferably, the Shore hardness of the material constituting the kneading reliefs and / or the support is greater than 40 Shore A, preferably greater than 60 Shore A.

The width of the front face of a kneading relief may be greater or less than the width of its base, the widths being measured in the same transverse plane. These widths of the base and the front face of a kneading relief can also be substantially identical. In a particular embodiment, the width of a kneading relief gradually decreases from its base to its front face, preferably regardless of the distance between the transverse measurement plane and the X axis. kneading relief may have a tapered shape from its base to its front face. The cross section of a kneading relief can be substantially constant regardless of the transverse plane considered, or variable. In one embodiment, the surface of the cross-section decreases progressively from the peripheral end of a kneading relief, that is, furthest from the X axis, to the central end of this kneading relief, that is to say the closest to the X axis. In particular, the kneading relief may have a tapered shape from its peripheral end to its central end. Preferably, regardless of the cross section considered, the height of a kneading relief is greater than or equal to the width of its base. The cross sections of the reliefs may be in particular square, rectangular, triangular, trapezoidal, all the edges of this section being rectilinear.

One or more edges may however be curved, in particular concave or convex. In one embodiment, as shown for example in FIG. 9g, over at least a part of its length, or even over its entire length, a kneading relief is inclined at an angle 13 with respect to its base plane. angle 13 may be greater than 45 °, or even greater than 60 ° and / or less than 80 °.

The cross section of a kneading relief may have axes of symmetry. In particular, a kneading relief may have a symmetry with respect to a surface passing through its positioning line and extending parallel to the axis X. Advantageously, if the positioning line is radial, the effectiveness of the kneading relief is the same whatever the direction of rotation of the support around the X axis.

The front face of a kneading relief may be in the form of a ramp, plane or not, generally inclined at an angle a with respect to a normal plane, the angle a being for example greater than at 5 °, or at 10 ° and / or lower than 45 ° or at 30 °. In one embodiment, the ramp extends over more than 50%, even more than 70% or more than 90%, or even substantially 100% of the length of the front face of the relief. The ramp can start from the central end face or the peripheral end face of the relief, or from a point between these two faces. In one embodiment where several kneading reliefs are arranged along the same positioning line (FIG. 1b for example), the ramp extends over more than 50%, or even more than 70% or more than 90%, or on substantially 100% of the distance between the central end face of the most central relief (radially innermost) and the peripheral end face of the most peripheral (radially outermost) kneading relief. The ramp can begin at any of these two faces or from a point between these two faces.

Whatever the embodiment, the local slope a 'of the ramp at a point M of the ramp (see Figure 10c) may be the same or different depending on the kneading relief considered and / or the positioning line considered. The local slope a 'can be constant (and then equal to a) or variable as a function of the distance to the axis X. In particular, it can increase with this distance, as represented for example in FIG. 10c. The variation of the local slope a 'may itself be variable or constant. For example, the slope may increase exponentially with the distance to the X axis, thus forming a springboard. The local slope a 'may be constant over a part of the length of the ramp, for example over more than 50%, more than 70%, or even more than 80% of the length of the ramp, and then be variable, especially at near the periphery of the support. The ramp can thus form a protuberance in the form of a tooth or tip at the periphery of the support, facilitating quick attachment of the skin and effective pleating (FIG. 10k). The shape of the front face of a kneading relief can be any and in particular be square, rectangular, trapezoidal, circular, triangular, symmetrical or not, with straight edges and / or curves. In one embodiment, this shape is identical to the shape of the corresponding base, the front face being superposable or offset, in a view along the direction of the axis X, with respect to the base. The width of the front face of a kneading relief can be variable from its peripheral end to its central end. For example, this width can progressively increase to mid-length of the kneading relief, and then gradually decrease. It can thus for example have the shape of a crescent. All the forms envisaged for the end faces are also possible for the bases or for the radial sections between the end faces and the bases, and in particular a triangular shape, the point being close to the axis X. As a variant, the front face of a kneading relief can take the form of an edge. Preferably, at least the leading edge of the front face, that is to say the front edge in the direction of rotation of the support, or even one or more of the other edges, is or are slightly rounded to limit the aggressiveness of contact with the skin.

For a given kneading relief, the maximum height may be more than twice and / or less than five times, or even four times, greater than the minimum height. The maximum height may be at the peripheral end face. The minimum height may be at the central end face.

Preferably, the maximum height of the most peripheral kneading relief of a set of kneading reliefs of a positioning line is at least twice and / or less than five times, or even less than four times, greater than the height. minimum of the most central kneading relief of this set. This maximum height may be at the peripheral end face of the most peripheral kneading relief.

The reliefs may have an elongated shape. They can extend over the positioning lines along their length. In particular a kneading relief, or even each kneading relief can extend over more than 50%, more than 70%, more than 80% or more than 90%, or substantially 100% of the length of the line positioning on which it is arranged. In the case of a circular perimeter support, for example disk-shaped, each kneading relief can extend over a radius and have a length greater than 50%, 70%, 80%, even 90% or 100% the length of this ray. This kneading relief can, for example, extend to the periphery of the support. All the aforementioned characteristics can be applied to all the knitting reliefs of a positioning line, or even to all the reliefs of kneading of the support. In one embodiment, all the kneading reliefs have substantially identical shapes. Preferably, the shape and arrangement of the kneading reliefs along a positioning line are identical regardless of the positioning line considered. All the knitting reliefs spaced apart by a determined distance from the X axis are then identical.

Support 30 The shape of the support is not limiting. In a first embodiment, this support may take the form of a substantially flat plate and perpendicular to the X axis. The flared envelope can then be obtained by adjusting the height of the kneading reliefs along the various positioning lines. so that this height decreases, progressively or not, from the periphery of the plate to the X axis. The height of the same kneading relief can decrease from its peripheral end towards its central end. When several kneading reliefs are arranged successively along a positioning line, it is also possible that the height of a kneading relief, or even all these knitting reliefs, is constant, provided that the constant height of a kneading relief is less than the maximum height of the adjacent kneading relief on the side of its peripheral end, that is to say its radially outer end, and greater than the minimum height of the kneading relief adjacent to its side; central end, that is to say its radially inner end. Alternatively, or in addition, the tray may also have a concave shape. The kneading reliefs on the same positioning line may then have variable heights, as described above, or have constant heights, the flared envelope may result from the heights of kneading reliefs, but also the shape of the support. To generalize the various embodiments, it is possible to define the axial position of a point on the front face of a kneading relief as the distance, measured along the X axis, between this point and a normal plane of reference PR passing through. by the point of intersection between the front face of the support (on which the kneading reliefs are connected) and the X axis (see FIGS. 10b and 10f). When the front face extends in a normal plane, the axial position of a point of the front face of a kneading relief is equal to its altitude, or height, measured from this front face. In general, along an intersection line D (see FIGS. 1, 10d) between the axial surface including a positioning line and the front faces of the kneading reliefs arranged along this positioning line, the axial position increases generally, continuously or discontinuously, possibly with one or more bearings, from the X axis to the periphery of the support. By general increases, it is meant that local decreases in the axial position, forming depressions along the line of intersection, are acceptable provided that their amplitude, i.e. the height of these depressions, less than 20%, preferably 10%, more preferably 5% or even 2% of the height difference between the maximum axial position point and the minimum axial position point on said intersection line D.

Preferably, the axial position shows no local decrease, or even no bearing, along said line of intersection D from the X axis to the periphery of the support. The support may be made of a material identical to or different from that of kneading reliefs. In particular, a transparent material can be envisaged so that the user can visualize the effect of the massage on his skin. The support may extend to the peripheral ends of the most peripheral kneading reliefs, or even beyond. It can also be interrupted without having reached said peripheral ends.

In one embodiment, the support has a certain flexibility so as to be elastically deformable during use. This flexibility makes it possible, during application to the skin, to improve the quality of the contact between the front faces of the kneading reliefs and the skin. Preferably, the support has, around the axis X, a central portion devoid of kneading reliefs. This central part makes it possible to increase the volume available for the folds of the skin. It also makes it possible to open one or more dispensing orifices, preferably substantially radial, and more preferably oriented along the median lines between the various positioning lines. The massage member according to the invention therefore makes it possible to spread out and effectively distribute a composition, in particular a cosmetic composition, including a care composition. In one embodiment, the support is traversed by a distribution channel for the passage of a composition to be applied. This distribution channel can in particular pass through the support from a front face carrying the reliefs of kneading to a rear face.

In one embodiment, the support comprises, on the opposite side to the kneading reliefs, a fixing end piece intended to be mechanically coupled to rotating drive means. This fastening tip may in particular extend along the axis X and have the shape of a hollow shaft traversed by a distribution channel opening itself, via one or more dispensing orifices, in the central part devoid of reliefs of kneading, in particular by means of a jetbreaker capable of preventing axial ejection of the product. So that the product delivered in this central part is not evacuated too quickly towards the periphery of the support, one or more ribs, for example cylindrical of axis X, can be arranged between the positioning lines, in the receiving spaces. Unlike the kneading reliefs, these ribs must not hinder the penetration of the folds of the skin in the reception spaces. These ribs may for example be flexible. The height of a rib is preferably less than the height of the kneading reliefs arranged at the same distance from the axis X, and preferably less than two-thirds, or even less than half that height. Preferably, the height of the ribs is determined so that they do not come into contact with the skin during use of the massage member. The ribs may extend to come into contact with the kneading reliefs or not. They can be continuous or discontinuous. Finally, they may constitute a peripheral skirt, for example substantially cylindrical X-axis, encircling the most peripheral kneading reliefs, and for example in contact with their peripheral ends. The support can have a circular perimeter to limit the risk of injury. In particular, it can have the shape of a flat and circular plate.

Application element The receiving spaces between the positioning lines may be empty or may be filled, at least in part, by an application element made of a deformable and / or compressible material. It is the same for the central part devoid of kneading reliefs. The applicator element may be a foam, in particular an abrasive foam allowing skin scrubbing, an open cell foam or having a slot or distribution channels allowing the flow of a composition, for example from an orifice dispensing, to an application surface, a sponge, a tuft of bristles, in particular flocked or stapled, or a combination of these application elements. The foam may be made of a material selected from the following list: Polyurethane, Polyether, Polyester, Polyvinyl Chloride, Polyethylene, EVA, Latex, Silicone, SIS, SEBS, Silicone Elastomer, Latex Elastomer, Nitrile Elastomer, Butyl Elastomer , Neoprene, NBR, SBR, this list not being limiting. The application element may have a composite structure with several layers of different natures, for example several types of foams.

The invention also relates to a massage member intended for kneading-twisting of human skin, this massage member comprising: a support provided to be rotated about an axis X; a plurality of kneading reliefs, preferably all identical, extending on a front face of the support along radial positioning lines angularly spaced apart at an angle of at least 20 °, or even at least 30 °; °, or at least 40 °, or even at least 500, the height of each kneading relief being decreasing from its peripheral end towards its central end, especially if the front face of the support extends in a normal plane to the X axis, or, more generally, along a line of intersection between, on the one hand, an axial surface including a positioning line and, on the other hand, the front faces of the reliefs of kneading arranged along said positioning line, the axial position 15 increasing generally, continuously or discontinuously, from the X axis to the periphery of the support, any local decreases of said axial position being always infé less than 20% of the difference in height between the maximum axial position point and the minimum axial position point on the said intersection line, the axial position at a point on the front surface of a kneading relief being defined as the Distance, measured along the X axis, between this point and a normal reference plane passing through a point of intersection between the support and the X axis. In particular, a single kneading relief, preferably of elongated shape, can be arranged along each determined positioning line. Rows of kneading reliefs may also be arranged along the positioning lines. Preferably, the positioning lines are equiangularly distributed around the X axis. All the optional features mentioned above can be applied.

In case of alternative rotation, the angular travel in rotation in one direction is preferably greater than or equal to 90 degrees. In general, a no-load rotation speed greater than 150 rpm, or even 200 rpm, and less than 400 rpm, or even 300 rpm, is well suited. In contact with the skin, the speed of rotation can be reduced, for example by being divided by a factor of at least two. In a variant of the invention, the device comprises means for fixing it to a shower head, said rotary drive means being configured to rotate the support around the X axis under the effect of the flow. water out of said pommel. The device according to the invention may comprise a motor, in particular an electric motor, capable of ensuring rotation of the support. The device may also comprise means for injecting a composition through the massage member by one or more distribution channels, in particular by at least one distribution channel opening into the central portion devoid of kneading reliefs of the support. and, preferably, means for controlling said injection allowing a continuous or temporary injection of said composition. It is then advantageous that the device further comprises a body configured to receive a container capable of containing or containing a composition to be applied. The massage member may be rotated about a geometric axis X of rotation which makes a zero or non-zero angle with the longitudinal axis of the container. A non-zero angle can improve ergonomics.

The device may comprise a control member of the distribution of the composition contained in a container, allowing the user to selectively distribute the composition. The control member may for example act on a valve stem of the opening container by tilting or depression.

The massage member may be removably mounted, which may allow to separate it for cleaning and / or replace it with another massage member selected according to the treatment to be performed. The device may also comprise means capable of vibrating the massage member axially, which, advantageously, allows percussion of the skin simultaneously with the kneading. The device may also comprise means for ensuring, simultaneously or not, a rotation and an axial vibration of the support. The device may also comprise suction means, preferably by a suction port disposed in the central portion free of kneading reliefs of the support.

The shape of the massage member according to the invention can be adapted, by routine tests, to the regions of the skin to be treated.

Container The container may be a pressurized container. The container may comprise a propellant, which may be mixed with the composition in the container. Alternatively, the propellant and the composition can be stored separately inside the container. The use of a propellant gas is advantageous in that it can make it possible to generate cold by expansion of the propellant gas and / or evaporation thereof. Cooling of the composition can create a pleasant sensation to the application, stimulate the microcirculation of the blood and promote the action of the composition. Cooling may also reduce the warming effect of the treated region related to the friction of the massage member thereon, if any. The composition and the propellant may be contained in the same chamber of the container or alternatively in separate enclosures. The composition may for example be contained in a flexible bag inside the container, this bag being subjected to the pressure of the propellant. The composition may also be contained in a compartment of the container which is separated from that containing the propellant by a piston which can move in the container as the emptying of the compartment containing the composition. The composition may optionally be mixed with a first propellant gas and the mixture constituted by the composition and this first propellant gas may be distributed through the pressure of a second propellant gas. All the possibilities disclosed in the application US 2006/0276731 A1, the applications FR 2 886 543 and FR 2 886 542 are applicable to the present invention. The propellant may be chosen for example from fluorinated or non-fluorinated hydrocarbons, dimethyl ether, propane, butane, isobutane, compressed nitrogen and compressed air.

The invention finally relates to a kneading-twisting process comprising the following steps: a) application to the surface of the skin of a massage member according to the invention; b) axial pressure and, simultaneously, rotating said massage member; In one embodiment, this method also includes the application of a cosmetic composition. In one example, the composition is applied without the massage member being rotated, which may allow for example to spread the composition on the region to be treated. The massage member is then rotated to knead the region on which the composition has been applied. In another example, the massage member is rotated in order to massage the region to be treated, without the composition being dispensed at first. Then, while the massage member is still rotated or alternatively while the massage member is stationary, the composition may be dispensed and spread over the previously massaged region. The composition can be dispensed with an expansion of a propellant gas that produces a cold action, which allows to create a hot / cold that can stimulate the treated region.

The distribution of the composition can be effected with an expansion of an expander gas which produces a foam at the exit of the applicator, which makes it possible to better spread the composition on the treated region for the purpose of cleaning or care. The region to be treated may be chosen in particular from the skin of the belly, back, thighs, buttocks, calves, hips, arms, neck or lower face.

Definitions Known relief is a protuberance protruding from the support so as to come into contact with the skin when the massage member is pressed on the latter, and having a rigidity enabling it to substantially retain its shape during use to drive the skin when the massage member is rotated about the axis X. This definition excludes in particular the aforementioned ribs. A flared envelope is a surface bearing on the front faces of the kneading reliefs of a massage member and diverging. In other words, this surface moves away from the normal plane PR when one deviates from the axis X. The flared envelope can diverge continuously or discontinuously, that is to say with possibly local variations contrary to a flare, including depressions allowing the surface to approach the normal plane PR when deviating from the X axis. The flared envelope can be concave. The amplitude of these depressions is however limited.

The flared envelope may diverge regularly or irregularly, for example because of the presence of bearings or a variable slope depending on the distance from the axis X. The flared envelope may in particular have an axial symmetry around of the X axis, or even be of revolution around this axis X, and in particular be of conical shape. It can be quadratic, and in particular ellipsoidal or paraboloidal.

The receiving space between two adjacent positioning lines is the X-axis disk sector, disposed between the kneading reliefs extending along these two positioning lines, which has the largest possible angular amplitude 0 (see FIG. Figures 4, 5, 11, 13a-c), this sector having a thickness equal to the maximum height of these relief kneading. This sector is delimited laterally by two plane portions intersecting along the X axis, referenced Q1 and Q2, angularly spaced from the angle O. It is also delimited by the front face of the support, by the flared envelope (surface Q3 ), and by a cylindrical dummy surface of axis X, Q4, passing through the peripheral end of the most peripheral kneading relief of said kneading reliefs.

In other words, when a plane is rotated about the X axis from the first positioning line to the second positioning line, the reception space starts at the angular position where the rotating plane ceases to be in contact. with any one of the kneading reliefs arranged along the first positioning line (angular position defined by Q1) and ends at the angular position where the rotating plane comes into contact, for the first time, with one of the reliefs of kneading arranged along the second positioning line (angular position defined by Q2). The angular extent of a receiving space is defined as the angle O. A plane perpendicular to the X axis is called a normal plane. A plane perpendicularly intersecting a positioning line is called a transverse plane. Axial surface, respectively axial plane, is a surface, respectively a plane, extending parallel to the axis X. A radial section of a kneading relief is called a section in a radial plane of section. The cross section of a kneading relief is a section in a transverse sectional plane. Longitudinal section of a kneading relief is defined as a section 20 along an axial surface and including the positioning line of this kneading relief. The basic plan of a kneading relief is the general plan according to which its base is fixed on the support. In the various figures, identical references have been used to designate identical or similar parts or members. Other features and advantages of the invention will become apparent on reading the following description and on examining the appended drawing in which: FIG. 1 represents, in perspective, a massage member according to the invention according to a first embodiment of the invention; - Figure 2 shows the massage member in section along the plane P1 visible in Figure 1; - Figures 3 to 6 show different variants of this massage member; - Figure 7 shows, in perspective, a massage member according to a second embodiment of the invention; FIGS. 8a to 8g show examples of radial sections of possible kneading reliefs for a massage member according to the invention, these sections being able in particular to be the sections at the level of the base or at the level of the front face of these reliefs. kneading; FIGS. 9a to 9h show examples of cross-sections of possible kneading reliefs for a massage member according to the invention; FIGS. 10a to 11b show examples of longitudinal sections of possible kneading reliefs for a massage member according to the invention; FIGS. 11 and 12 show a massage member according to a third embodiment of the invention; in perspective and in section along plane P1 of FIG. 11, respectively; - Figures 13a to 13c show, in top view, examples of massage member according to the invention; FIG. 14 is a diagrammatic elevational view partially broken away of an exemplary device according to the invention; - Figure 15 is a schematic and partial longitudinal section of the device of Figure 14; - Figure 16 shows, in a sectional plane including the X axis, a massage member according to the invention adapted to the device shown in Figures 14 to 15; FIGS. 17 and 18 show schematically, in front view and in perspective, examples of assemblies according to the invention; FIG. 19 represents a detail of a device according to the invention; - Figure 20 shows a massage member according to the invention to be implemented manually; and FIG. 21 illustrates the use of the massage member of FIG. 20. The massage member 10 shown in FIG. 1 comprises a support 12 and four kneading reliefs 141, 142, 143 and 144. The support 12 comprises a substantially flat plate 16 having the shape of an X-axis disk and having two main faces, namely a substantially planar front face 18 and a rear face 20. The four kneading reliefs 141, 142, 143 and 144 are of identical shape and arranged symmetrically about the axis X. For the sake of clarity, only the shape and arrangement of kneading relief 141 are described in detail below.

For an identical or similar characteristic, the references given in the figures relating to the various kneading reliefs are the same, but assigned an index 1, 2, 3 or 4 depending on whether they refer to the kneading relief 141, 142, 143 or 144, respectively.

The kneading relief 141 is fixed rigidly by its base 221 on the front face 18 of the plate 16. For this purpose, as shown in FIG. 2, it may comprise pins 19 which are housed in complementary housings of the plate 16. kneading reliefs may however be fixed by any means on the plate 16, and in particular be integral with this plate or be overmoulded on this plate.

The base 221 has a substantially rectangular shape extending longitudinally along a radial positioning line L1. The width of the base 22 may for example be greater than 5 mm, or 6 mm, and / or be less than 15 mm, or 10 mm, or even 8 mm. Axially, the kneading relief 141 extends from the base 221 to a front face 241. It further has two side faces 261 and 281 extending from the base 221 to the front face 241 and, at its central ends 301 and peripheral 311, central end faces 321 and peripheral 331. The front face 241 has the shape of a ramp. This ramp extends along a plane P24 from the central end 301 to the peripheral end 311 of the kneading relief 141. Its inclination relative to the front face 18 of the plate 16 is substantially constant and preferably greater than 10 ° and / or less than 20 °. An inclination of 15 ° is well adapted. The maximum height H1 of the kneading relief 141, at the peripheral end 311, is at least two times greater than its minimum height h1, measured at the central end 301. The maximum height H1 may be greater than 5 mm, or even 6 mm, and / or less than 20 mm, or even 15 mm, a height H1 of about 10 mm being well adapted. The front face 241 is substantially rectangular and has a width less than the width of the base 221. Its longitudinal axis R1, the axis X and the positioning line L1, constituting the longitudinal axis of the base 221, belong to the same axial plane P1. The axial plane P1 constitutes a plane of symmetry for the kneading relief 141. The lateral faces 261 and 281 being substantially planar, all the cross sections of the kneading relief 141 thus have the same regular pyramid shape with a truncated crown.

The set of front faces of the kneading reliefs extends in a concave flared envelope E, of axis X (see FIG. 12). The kneading reliefs are distributed substantially equiangularly about the X axis, their respective positioning lines thus forming two by two angles of 90 °. The limited width of the kneading reliefs makes it possible, between the various kneading reliefs, to accommodate reception spaces 3412 between the kneading reliefs 141 and 142, 3423 between the kneading reliefs 142 and 143, 3434 between the knitting reliefs 143 and 144, and 3441 between the kneading reliefs 144 and 141.

The limited width of the kneading reliefs allows the receiving spaces to extend angularly over more than 30 ° around the X axis. Along the positioning lines, the kneading reliefs do not extend to the X axis, but are interrupted so as to provide a central portion C without kneading reliefs. In the middle of this central part C, the support 12 comprises a X-axis baffle 40 in which are provided four distribution orifices 4212, 4223, 4234 and 4241 opening, substantially radially, into the receiving spaces 3412, 3423, 3434 and 3441, respectively, substantially along the bisectors between the positioning lines L1 and L2, L2 and L3, L3 and L4, and L4 and L1, respectively. As can be seen in FIG. 2, these dispensing orifices communicate with a dispensing channel 44 opening on the side opposite to the kneading reliefs with respect to the plate 16. The dispensing channel 44 passes right through a fastening nozzle 50 intended to attaching the massage member 10 to an electrical apparatus capable of rotating it about the axis X. The dispensing channel 44 and the dispensing orifices are intended for the injection of a composition, and in particular a draining or slimming or relaxing or treating product. To facilitate the application of this composition, the receiving spaces may be filled, partially or completely, by an application element 45 into a compressible material, as shown in FIG. 3, that is to say not substantially opposing the penetration of the folds of the skin during use of the massage member according to the invention. The application element 45 may in particular be constituted by a foam, in particular a sponge, an open-cell or closed-cell foam, or comprising distribution channels allowing the composition to be conducted to the surface of the skin. , abrasive or not, a tuft of hair, or a combination of these elements.

To further improve the efficiency of the injected product, obstacles can be arranged in the receiving spaces. In particular, as shown in FIG. 4, ribs extending along an imaginary cylinder of X axis, referenced 52, may be provided. These ribs may be continuous or discontinuous, extend to come into contact with the knitting reliefs between which they are arranged, or even form a continuous skirt at the periphery of the plate. The height of the ribs and the nature of their constituent materials must, however, be adapted so as not to hinder the penetration of the folds of the skin between the kneading reliefs when the organ according to the invention is used.

As shown in FIG. 5, the plate 16 does not necessarily extend up to the peripheral end of the kneading reliefs. As shown in Figure 6, the plate 16 may also be perforated, having for example, as shown, windows 53 in the form of ring sectors. The flared envelope E of axis X may result, as shown in FIG. 1, in an inclination of the end faces of the kneading reliefs with respect to the plane of the front face 18 of the plate 16. In a variant, as shown in FIG. 7, the kneading reliefs may have a substantially constant height, the flared envelope resulting from the substantially concave shape of the front face 18 of the plate 16. Thus, in this figure, the positioning lines, substantially rectilinear, form an angle y with the X axis, being less than 90 °. In general, the shape and arrangement of kneading reliefs are not limited. For example, the base and the front face of a kneading relief, which may be the same or different, may be not only rectangular, as in the embodiments of FIGS. 1 to 7, 8a and 8b, but may also be any other form. FIGS. 8a-g provide examples of possible shapes, in particular a trapezoidal shape as in FIG. 8c, a triangular shape as in FIG. 8e, a crescent shape as in FIG. 8g, with one or more non-rectilinear sides and in particular concave or convex (Figures 8d, 8f). The number of kneading reliefs extending along a positioning line is not limited and may in particular be equal to 1, 2, 3, 4 or 5. The spacing e between two adjacent kneading reliefs s' extending along a positioning line may be constant regardless of the two kneading reliefs considered, as in Figure 8c, or be variable according to the considered kneading reliefs, such as the spacings el and e2 in Figure 8a.

The cross sections of the kneading reliefs may be arbitrary or non-symmetrical, and may in particular have the shapes shown in FIGS. 9a-h. They may for example be rectangular, as shown in FIG. 9a, trapezoidal for example as in FIG. 9h, possibly with a side extending perpendicular to the base, as represented in FIG. 9b, with possibly one or more convex edges, as in Figure 9c or concave, as in Figure 9d. The cross-sections may also be triangular and symmetrical, as in FIG. 9e, with a side perpendicular to the base, as in FIG. 9f, or inclined with respect to this base, as represented in FIG. 9g, one of the sides of the cross section forming an angle less than 90 ° with the base plane. However, it may be preferable that the cross section is not inclined toward the support, as in Fig. 9g, to facilitate cleaning of the massage member. When one of the sides of the cross section of a first kneading relief is inclined towards the base plane, that is to say forms with it an angle β less than 90 °, the angle of inclination and the the shape of the kneading relief, and in particular its height, should preferably make it possible to prevent this first kneading relief from being superimposed on a second kneading relief of an adjacent positioning line, and, more preferably, that this first kneading relief does not come into contact with this second kneading relief. The cross-section of the kneading reliefs may have a plane of symmetry P'1, as shown in FIGS. 9a, 9e and 9h, the plane P '1 being able in particular to merge with an axial plane P1. The longitudinal sections of the kneading reliefs can also be varied as illustrated in Figures 10a-10j. The longitudinal sections may in particular be trapezoidal (FIGS. 1-6), rectangular (FIG. 7) and parallelepipedal (FIGS. 10e, 10f). An edge, and in particular the upper edge of the longitudinal section, may also be non-rectilinear and in particular concave, as shown in FIG. 10c. It may also have local irregularities 60, for example so that the front surface has pins, streaks or balls, as in Figure 10i. The local irregularities do not, however, call into question the overall concave shape of the flared envelope E. The local irregularities 60 may extend the entire length of a kneading relief or only a part thereof. Similarly, they may extend over the entire width of the kneading relief or only part of this width. Their number is not limiting.

Preferably, the height of the local irregularities, measured along the X axis, is less than 20%, preferably 10% or even 5%, or even 2%, of the local height of the kneading relief considered.
