Description

  The present invention relates to a massage and beauty care device intended to be applied to the body surface of a user.

  Microneedle therapy is a treatment aimed at stimulating the skin and increasing the production of collagen and elastin fibers.

  This new generation of collagen and elastin improves skin texture and reduces skin damage.

  This procedure is performed using a device comprising a group of ultrafine needles intended to pierce the skin and penetrate the dermis layer. This can be done in conjunction with a beauty care product such as a cosmetic or therapeutic cream.

  More specifically, microneedles create microchannels, which facilitates penetration of the product into the deep skin.

  This is therefore an invasive technique.

  Such devices are described in Patent Document 1, Patent Document 2, and Patent Document 3, in particular.

  Specifically, Patent Document 3 describes a roller carrying a protruding group of needles intended to pierce the skin and penetrate the dermis layer. This roller distributes the related product well.

  However, these devices can only be used in therapeutic and invasive modes where the needle is effective and punctures the skin. Thus, the user cannot simply use this roller for product application without puncturing the skin with a needle. This is a single “all-or-nothing” mode of operation.

  These devices use very fine needles, but the use of needles is not always comfortable. In addition, particularly sensitive skin may be marked or reddish, which is temporary but unattractive.

  Furthermore, it is not always necessary to puncture the skin and the user may simply want a somewhat deeper massage effect.

  Specifically, the application of massage or stimulation elements to the skin is sufficient to activate the microcirculation locally, which promotes cell regeneration and also helps penetrate the active product.

  Specifically, activation of the skin microcirculation serves four main functions: supply of nutrients to cells of various skin layers; maintenance of arterial pressure by vasoconstriction; long-term illness due to body weight Blood-tolerant skin; and vasomotor reactivity required for thermoregulation.

Chinese Utility Model No. 2197042 Specification Korean Published Patent No. 20100005533A International Publication No. 08004818 Pamphlet

  Accordingly, there is a need for a skin stimulation device that provides the desired benefits while providing a more comfortable and comfortable use. There is also a need for multi-mode devices that allow gradual application effects.

  To achieve this, the present invention is directed to a massage and beauty care device intended to be pressed against a user's body surface with at least one rotating member carrying at least one protruding rigid pin. .

  The device is associated with at least one peripheral cushion having an outer surface intended to contact the application body surface with the pin, the cushion having a maximum thickness and the pin against the user's body surface It can be elastically deformed between a rest position that cushions the pressure to the point where it is almost undetectable and a compressed position where the thickness of the cushion is reduced and the pin can apply a pressure that can be sensed to the surface of the application body. It is characterized by that.

  Thus, a cushion associated with the pin that cushions the pin's pressure on the body surface, in particular making the pin insensitive or nearly insensitive, and the pressure that the pin can detect on the user's skin. By providing a cushion that can be elastically deformed between compression positions that can be applied, the user can determine the applied pressure by himself and obtain a somewhat deeper massage effect.

  Such an applicator makes it possible in particular to spread the cosmetic product on the skin using the surface of the cushion. When the user presses, the cushion is compressed, and the rigid pin itself is not compressed, so that the end of the rigid pin protrudes. This allows the skin to be massaged or poke, activates the microcirculation, prepares the skin, and promotes penetration of the active product.

  Such devices can be used on both the face and scalp, hands or any other part of the body, as the user himself can easily adjust the massage force.

  In addition, when applied without significant pressure or without any force other than that required to roll the rotating member, the user may use the device to simply apply a cream or any other cosmetic or cosmetic product. Can do.

  A “pin” generally has a long overall shape with a base interposed for connection to a rotating member (forming the core) and an opposite free end intended to apply pressure to the user's skin. Means an individual massage element in the shape of a scale.

  In particular, the pin may take the shape of a cone and may have a narrow pointed end. Where appropriate, the pin may be a needle.

  Alternatively, any form of end that produces a massage effect can be contemplated.

  The pin generally extends in a direction having a radial component. Preferably, the pin extends substantially radially.

  Preferably, the pin is made of a rigid plastic material, in particular a thermoplastic material. Preferably, the pin is made as an integral part of the rotating member, in particular by molding.

  “Rigid” means that it is relatively hard compared to the cushion and is preferably not deformable even when applied with pressure.

  Quite clearly, the stiffness of the pin will depend on the massage effect to be provided, and those skilled in the art will be able to adjust the stiffness of the pin accordingly. This stiffness can be adjusted in particular by changing the material and / or cross-sectional width of the pin.

  By way of example, the tip of the pin has a cross section with dimensions smaller than 0.3 mm, or even smaller than 0.1 mm. The base of the pin itself may be wide (including for example 2-3 mm) or thin (for example including 0.4-1 mm) depending on the desired stiffness.

  The height of the pin is not important. In order to facilitate the production of very elongated pins by molding, a short height may be preferred so that injection molding and release of the pins can be made easier. If the pin has a wide base, the pin can be raised without difficulty.

  The rotating member advantageously carries a number of spaced apart pins, all of which are associated with a cushion, preferably a cushion shared by the pins.

  Preferably, the rotating member is a roller attached to rotate. By using such a member, it is easy to attach this member to the apparatus, and the apparatus can be easily moved on the surface of the application body. Where appropriate, the roller also allows the correct application of the relevant cosmetic product.

  Advantageously, the rotating member is detachably attached. Therefore, it is possible to provide several types of rotating members that can be exchanged according to a desired application effect. The rotating member can also be easy to clean or wash.

  The diameter of the rotating member can typically range up to about 50 mm.

  The diameter of the rotating member may in particular be comprised between 10 and 20 mm, preferably 10 to 15 mm. Such dimensions are particularly well suited for facial applications. Such dimensions in particular make it possible optimally to trace a curved surface such as the face.

  Advantageously, the rotating member comprises a plurality of pins spaced apart and distributed around the periphery of the rotating member. The end of the pin thus defines an envelope surface on which the cushion is positioned.

  Preferably, the pins are aligned well enough to allow the user to feel them individually.

  For this purpose, the pins need to be arranged at a sufficient interval. Preferably, the distance between two adjacent pins can be greater than 3 mm, or even more preferably greater than 5 mm.

  Preferably, the pins are arranged in at least one row, preferably along the generally longitudinal axis of the rotating member.

  Advantageously, the pins are arranged in 5 rows or more and less than 10 rows. Advantageously, the pins are arranged in 6-8 rows, preferably 6 rows.

  This is because if there are fewer than 5 or 6 rows, there is a risk of “shaking” when the device is advanced along the surface of the applicator. Conversely, if there are more than 8-10 rows, the pin spacing is too tight and the spacing between the pins is no longer sufficiently apparent. The associated cushion cannot be fully compressed between the pins, resulting in a reduced massage effect.

  Alternatively or additionally, the pins are arranged in at least one ring surrounding the generally longitudinal axis of the rotating member. Preferably, the pins are arranged in four rings.

  Advantageously, the cushion is at least one elastomeric material, in particular SEBS (styrene-ethylene-butadiene-styrene), SBS (styrene-butadiene-styrene), Exact®, Santoprene®, silicone, Desmopan®. ™, Vistamaxx®, nitrile, butyl, Engage®. Such extremely compressible materials are particularly suitable for making cushions.

  According to one first embodiment, the cushion surrounds the pin without covering it, the cushion being in a rest position where the pin is flush with or retracted from the outer surface of the cushion, and the pin is It can be deformed between the compression position protruding from the cushion.

  Thus, when a compressive force is applied, the material forming the cushion is compressed between the pins and the pins come into direct contact with the user's body surface, resulting in a significant massage effect.

  Preferably, the cushion is made by overmolding around the pin on the rotating member. The device thus remains relatively simple in terms of its design and manufacture, and the cushion can be made directly on the rotating member after it has been manufactured.

  According to the second embodiment, the cushion covers one end of the pin. When compressive force is applied, the material forming the cushion is compressed onto the end of the pin. The thickness of the cushion decreases until the user feels the stiffness of the pin and its effect on the skin. The pins do not come into direct contact with the user's body surface and a minimal amount of cushioning can be provided.

  Preferably, the thickness of the cushion on the end of the pin is 1 mm or less in the uncompressed stationary state.

  Furthermore, in such an embodiment, the device can be easily cleaned after use of the product.

  Advantageously, the cushion takes the form of a sleeve arranged around a rotating member resting on the pin.

  According to an alternative embodiment, the sleeve is made of a heat shrink material. This may in particular be a polyolefin. Therefore, the sleeve may be made larger in diameter than the combined assembly of the rotating member and the pin, making the sleeve much easier to install.

  In addition, the outer peripheral surface of the cushion is not planar after the sleeve has shrunk partially over the pin. Specifically, the surface has a hollow region between the pins. This particularly emphasizes the pin area. The hollow area also becomes a product reservoir, if appropriate.

  The invention also relates to a device according to the invention, characterized in that it further comprises a reservoir intended to contain a cosmetic product.

  The present invention will be further understood by reading the following detailed description in conjunction with the accompanying drawings.

1a and 1b are schematic illustrations of a longitudinal section and a side view, respectively, of an apparatus according to a first alternative of the first embodiment. 2a and 2b are schematic diagrams according to a second alternative of the first embodiment. 3a and 3b are schematic diagrams according to a third alternative of the first embodiment. Figures 4a and 4b are schematic illustrations of a longitudinal section and a side view, respectively, of an apparatus according to a first alternative of the second embodiment. 5a and 5b are schematic diagrams according to a second alternative form of the second embodiment. FIG. 6 is a schematic diagram of a longitudinal section of a device according to any one of the preceding embodiments attached to a cosmetic product reservoir and dispensing system.

  1a and 1b show a massage and beauty care device 1 according to a first embodiment.

  The apparatus 1 includes a cylinder 2 mounted for rotation about a spindle 3. The spindle 3 comprises end pins 4 intended to allow installation between arms of a yoke (not shown) connected to a gripping member, for example a handle. The cylinder has a length of about 22 mm and an outer diameter of about 8.2 mm.

  The cylinder 2 carries a pair of radially projecting pins 5 around it. More specifically, the cylinder 2 carries a set of six longitudinal rows, each of four pins. These rows are evenly distributed around the cylinder 2.

  The pins 5 are arranged at intervals of 5.5 mm in the longitudinal direction. The height of the pin 5 is about 1.5 mm, and the total outer diameter of the cylinder 2 is 11.2 mm. The pin 5 has a base having a width of about 0.4 mm. The free end or tip of the pin 5 has a radius of 0.075 mm.

  In this way, the assembly comprising the cylinder 2 / spindle 3 and the pin 5 forms a spiked roller.

  The roller may in particular be made by injection molding of a relatively hard thermoplastic material.

  According to the present application, the flexible material is shaped to surround the pin 5 around the cylinder 2 to form the cushion 6. The flexible material is in particular a thermoplastic elastomer.

  More specifically, the flexible material is overmolded onto the cylinder to a thickness such that it is flush with the tip of the pin in an uncompressed state.

  Thus, the cushion 6 has a compressible outer surface intended to be in contact with the application body surface.

  The cushion 6 has a maximum thickness and the rest position is flush (uncompressed) with the tip of the pin 5. The cushion 6 has a reduced thickness and the tip of the pin 5. It is possible to elastically deform between the compression position protruding from the cushion 6.

  Therefore, in the rest position, the pin 5 cannot be pressed against the application surface by being blocked by the cushion 6, and the pin 5 does not give the user a perceivable feel.

  In contrast, in the compressed position, the cushion 6 is slightly retracted from the tip of the pin 5, and the pin 5 can exert its massage effect on the application body surface.

  Of course, it is quite possible to overmold the soft elastic material so that it extends beyond it rather than just flush with the tip of the pin 5 in the rest position. It simply increases the pressure required to activate the pin.

  2a and 2b show a massage and beauty care device 10 according to an alternative form of the first embodiment.

  The device 10 differs from the device 1 in that it essentially comprises a rotating member 11 made as a single piece. The diameter of the rotating member 11 (excluding the cushion and excluding the pin) is about 5 mm.

  In addition, it comprises a slightly rounded edge cushion 16. More specifically, the cushion has an oval longitudinal cross section. Therefore, the outer diameter of the device 10 is slightly larger at the center than at the end. Furthermore, the end has a rounded cross section in the form of an arc.

  It will also be noted that the device 10 comprises a pin 15 that is slightly longer and thinner than the device 1. Accordingly, the base portion of the pin 15 is widened in order to maintain good rigidity.

  3a and 3b show a device 20 that differs from device 10 only in the size of the pins 25. FIG. Specifically, the pin 25 has a wider base and is not very elongated.

  Therefore, the pin 25 has a cross section with a not so steep slope. This inclination tends to hinder cushion compression.

  Thus, it will be understood that the compression characteristics of the cushion can also be controlled by the shape of the pin. Thus, it is possible to adjust the force that the user needs to apply to activate the pin.

  4a and 4b show a device 30 according to a second embodiment. The device 30 essentially differs from the previously described devices 1, 10 and 20 in that it comprises a cushion 36 that covers the tip of the pin 35.

  According to this alternative of the illustrated embodiment, the cushion 36 is made in the form of an elastomeric sleeve that is placed around the rotating member 11 over the pin 35.

  The elastomer sleeve forming the cushion 36 is mounted by expanding the mouth of the sleeve using a pliers and sliding it on the rotating member 11 and its pin 35, such as a sock.

  Preferably, the sleeve has an elastomer wall with a thickness of 1 mm or less. Obviously, the cushioning effect also depends on the compressibility of the elastomeric material used.

  In order to hold the cushion in place and reduce the possibility of it moving in the longitudinal direction, the rotating member 11 can be fitted with end plates 37 each acting as a longitudinal end stop.

  The end plate 37 may also serve as a radial end stop and help limit cushion compression.

  In the rest position, the cushion 36, and more specifically the peripheral wall of the sleeve forming the cushion, has a maximum thickness. This thickness is defined so that the feel of the pin 35 is not given to the user or only very weakly.

  In contrast, when a higher applied pressure is applied, the elastomeric material of the cushion 36 is compressed between the user's body surface and the tip of the pin 35. The thickness of the cushion 36 is not sufficient to hide the pin, so the pin exerts its massage effect on the applied body surface.

  Figures 5a and 5b show an apparatus 40 according to an alternative of the second embodiment. The device 40 differs from the device 30 described above in that the sleeve forming the cushion 36 is made of a thermocompressible elastomeric material, in particular polyolefin.

  Accordingly, a cushion 36 having a diameter larger than the entire diameter of the rotating member 11 (that is, including the pin 35) is produced, which facilitates the mounting thereof.

  When this assembly is heated, the sleeve forming the cushion 36 contracts. The final device 40 has a non-smooth peripheral surface.

  FIG. 6 shows the massage and beauty care device 50 attached to the cosmetic product P reservoir 101 and dispensing 102 system 100.

  The massage and beauty care device 50 may in particular be a device 1, 10, 20, 30, 40 as described above.

  The dispensing system 102 can be a pump, a compressible flexible tube, an aerosol or any other known dispensing system 102.

  In general, the distribution system 102 includes at least one distribution orifice 103 connected to the reservoir 101 by at least one distribution line 104. A blocking system 108 for selectively blocking the distribution line 104 or the orifice 103 may be added to the apparatus.

  The dispensing orifice 103 opens substantially facing the peripheral surface of the massage and beauty care device 50, so that the product P can be distributed over at least the outer peripheral surface of the cushion.

  Alternatively or additionally, the product P may be applied separately, for example by hand, and housed in a separate reservoir.

  Examples of particularly suitable products P include beauty care creams, anti-cellulite creams, anti-aging creams, moisturizing creams, creams that work on the feet and veinotonic creams. Such products are beneficial for microcirculation stimulation by the device according to the present application.

  Furthermore, if appropriate, the rotating member that supports the pin can potentially be replaced with a fixed support member. At this time, the pin is supported so as to protrude from a planar or curved outer surface.
