  In the range of body or facial massage, there is a need for an end piece that enhances the sense of repose while improving blood or lymph circulation, for example, to provide a decongestant effect in the area around the eyes. It has been.

  There is a need for a massage end piece that is soft in the face cleansing or care range but that is effective to obtain clean skin that is smooth and free from dullness and redness. For this reason, the purpose of facial cleansing is P.A., especially for oily skin or skin that tends to acne. It is to avoid bacteria such as P. acnes from growing in the pores of the skin. In skin known as normal to dry skin, the main purpose of facial cleansing is to remove dead skin.

  It also has a low-cost massage end piece that can be attached to any device that has a cosmetic composition packaged, especially when those devices contain a facial cleansing active. There is a need to provide.

  Further, there is a demand for a massage end piece that can perform various levels of skin cleaning by the operation.

  There is also a need for a massage end piece suitable for facial depressions and undulations so that the cheekbone and both sides of the nose can be cleaned.

  There is also a need for a massage end piece that provides a new type of sensation while properly applying cosmetics or performing deep cleaning, and that massages to improve blood circulation and lymph circulation.

  The object of the present invention is to propose a rotating applicator with upright elements distributed at various heights on the base so that the highest element pressurization and the shortest element relaxation on the skin alternate. Is to solve all or some of the problems identified above.

The subject of the present invention is
An end piece comprising a base and at least two elements upstanding from the base;
-A body configured to receive the end piece;
-Means for rotating the end piece about the axis (X) relative to the body,
The end piece has a cross-sectional profile in a plane including the axis (X), which fluctuates during rotation;
The axis of rotation (X) is perpendicular to the base (2);
Each cross-sectional profile is a cosmetic device with a single maximum value.

  Advantageously, this end piece comprises at most one symmetrical central plane passing through the axis (X).

  According to the invention, the upright elements each terminate at a free end. This end will be in contact with the surface to be treated, especially the skin, during use of the device.

  With the device according to the invention, it is possible to alternately apply upright element pressure against the skin during rotation of the end piece so as to improve the circulation.

  With the device according to the invention it is possible to apply different pressures to successive areas of the skin during the movement of the end piece in order to perform a more active massage with a stronger influence. Various pressure levels can be applied alternately to achieve improved relaxation.

  The invention also relates to a cosmetic method comprising the use of the above device.

  According to the invention, the “center plane” is understood as meaning the plane that passes through the axis of rotation (X) of the brush and is perpendicular to the base.

  “Cross section” is understood as meaning the cross section of the base along the central plane.

  An “angular space” is understood as meaning the angle between two central planes that are offset by an angle α around the axis (X).

“Each cross-sectional outline contains a single maximum” means that each cross-sectional outline
This is the case with either the highest single point or the highest point single region. According to a first preferred embodiment of the invention, the maximum value is located at one of the two ends of the cross-sectional profile.

  The “maximum value” is the maximum height of the upright element measured from the base.

For each cross section
-A single upright element of maximum height,
-Or any of a plurality of upright elements of maximum height will be present, in the latter case the plurality of upright elements being located next to each other.

According to a second preferred embodiment of the invention, the cross-sectional profile has two regions: a first region comprising a first upstanding element, all having a first height (h1),
-Composed of a second region comprising a second upstanding element, all having a second height (h2), the first height being lower than the second height.

  The present invention also relates to a kit comprising the above device.

  The invention also relates to an end piece as defined above.

  Advantageously, the end piece has at least two different cross sections at spaced apart angles. These cross-sections are obtained by comparing two cross-sections of the brush at two different central planes.

  In one particular embodiment, the end piece does not have a symmetrical central plane through the axis (X).

  The device according to the invention is very satisfactory due to the fact that when the endpiece is viewed from the side in a direction perpendicular to the axis of rotation, the endpiece has a profile that varies when rotated around the axis (X). It is possible to obtain a good quality cleaning and massage.

  In one particular embodiment, each cross section of the base passes through at least one extreme between its two lateral ends. This extreme value may be a maximum value or a minimum value, and the cross-section of the base can pass between one maximum value and one minimum value between its two lateral ends.

Advantageously, the cross section of the end ^piece, between 0.2 cm 2 to 50 cm ^2, and more specifically with a surface area between ^{1 cm} 2 to 20 cm ^2.

  Preferably, the edge of each cross section through the free end of the upstanding element is curved.

  “Curved” is to be understood as meaning “does not form a straight line”, and thus a broken line is a curved line within the meaning of the present invention.

  Thus, the cross-sectional edge can have a greater curvature on one side and a smaller curvature on the other side, or a straight or substantially straight portion, a curved portion, Can be provided.

Preferably the surface area of the base is greater than 3 cm ² , preferably greater than 5 cm ² . This dimension is particularly suitable for facial contours. Its surface area is preferably less than 150 cm ² . The dimension between 30cm ² ~150cm ^2, conforms to the contour of the body (thigh, buttock, abdomen, back, etc.).

Advantageously, the base has a total surface area occupied by the upstanding elements (4) (S), the surface area (S) is between the measured ^{1cm 2 ~4cm} 2, preferably ^{2cm 2 ~3cm} 2 Between.

When rotating the massage and application device end piece by the drive means, the rotation speed of the end piece may be, for example, between 150 and 400 rpm, preferably between 200 and 300 rpm.

  The end piece can be rotated about a geometric rotation axis that is fixed relative to the body. As a variant, the end piece may be rotated around a geometric axis of rotation that can be moved relative to the body. If necessary, the endpiece motion may be eccentric, which spreads the composition more evenly and with less noticeable boundaries between the treated and untreated areas. Which is probably advantageous, for example in the case of artificial tanning creams.

  The end piece can be rotated about a geometric axis of rotation that forms an angle of zero or non-zero degrees with respect to the longitudinal axis of the container. Ergonomics can be improved at angles other than zero degrees.

  This end piece can be removably attached to the massage and application device, thereby cleaning the end piece and / or replacing or using another end piece selected depending on the procedure to be performed The applicator device can be separated for later disposal.

The material upright element forming the upright element can comprise an elastically deformable and / or compressible cellular material. This material may be a foam. The foams are listed below: polyurethane, polyether, polyester, polyvinyl chloride, polyethylene, EVA, latex, silicone, SIS, SEBS, silicone elastomer, latex elastomer, nitrile elastomer, butyl elastomer, Neoprene®, Although it can produce from the material selected from NBR and SBR, it is not limited to this list.

  An upright element can have multiple structures with different properties, for example a composite structure with several types of foam.

  The upright element can have any shape. Upright elements can have a circular, elliptical, or polygonal cross-section, such as a triangular, square, hexagonal cross-section.

  The upright element can have abrasive properties. “Abrasive properties” should be understood as meaning a surface that, when moved on the skin, removes at least some of the dead cells from the surface.

Such a surface can be characterized by a polishing power of 0.01 to 0.03 g / cm ² / min. The polishing power corresponds to the amount of plaster removed per minute per square centimeter of the polished surface applied to a plaster piece having a thickness of 50 mm using a 135 W Black and Decker CD400 polisher. The pressure applied to the strip is due to the weight of the polisher when restraining the motion of the polisher in the plane of the polishing surface.

  Such upright elements are obtained by considering a substantially rigid cellular material or by incorporating hard particles into the flexible cellular material.

  An example of a polishing surface is a nonwoven peel pad sold by 3M.

  The foam may be a soft and flexible foam, particularly suitable for spreading cosmetics, sometimes also known as a sponge.

The upstanding element may be, for example, a hydrophilic cross-linked polyester foam, for example having a density equal to 32 kg / m ³ .

  Sponges have traditionally been used to apply foundations, and NBRs such as Yukilon® from Penthouse Group are also conceivable.

  The upstanding element may be a hot compression foam. Thermal compression allows the foam surface to undulate and / or be combined with an elastic fabric, thereby foaming a fabric feel that is flexible but more comfortable than a plastic fabric It can be held in the body.

An example of a heat-compressed foam is a closed-cell foam made of polyolefin, for example, a heat-compressed polyethylene having a specific weight of 33 kg / m ³ combined with an elastic fiber such as Lycra (registered trademark).

  The upright element may be a file made of plastic material, metal or glass.

  The upstanding element may be made of an injection-molded flexible plastic material, such as an elastomer, and has a undulation for massage, such as a pointed end, a rounded end, and a circular, square, or triangular cross section Can have spikes with a length of, for example, between 1 mm and 40 mm, or balls with a cross-section that is circular or oval, and with a height of, for example, between 1 mm and 20 mm.

  The upright elements are made of an elastomer such as SEBS or silicone, for example.

  The upstanding element may be a brush made of synthetic or natural bristles, for example a bristle brush having a tufted bundle of polyamide or PBT having a diameter of between 0.05 and 0.2 mm, in particular having a diameter of 0.075 mm. Nylon (registered trademark) 6.12 may be used, and these bristles are polished and ground to be extremely soft when in contact with the skin.

Implanting the upright element "End of the upright element" means the tip located on the main extension axis that is farthest from the base of the upright element and extends in the direction of the free end from the attachment zone to the base Please understand as a thing.

  “Height of upright elements” is to be understood as meaning the distance measured along the main extension axis of the upright elements in the direction of their free ends. Preferably, the height of the upright element is between 0.1 and 3 cm.

  “Upright element thickness” is to be understood as meaning the maximum value of the cross-section of the upright element measured in the zone of attachment to the base of the upright element. Preferably, the thickness of the upstanding element is between 0.1 mm and 0.5 cm.

  Advantageously, the device is upright such that the height difference between two elements of extreme dimensions is greater than 0.2 cm, preferably greater than 1 cm, more preferably greater than 1.5 cm. With elements. This difference makes it possible to effectively alternate the highest element and the relaxation by the shortest element to the skin.

  The invention also relates to an assembly comprising a cosmetic container comprising a through-hole in which the end piece defined above is received.

  In particular, the container may be a tube or a bottle.

  It is understood that “two elements of extreme dimensions” are elements having a maximum height on the base and elements having a minimum height on the base.

  FIG. 1 shows a device 1 made in accordance with the present invention.

  The device 1 comprises a body 3, which can have an end piece 5 defining an application surface that will come into contact with the skin.

  The device 1 is manufactured according to Patent Document 4, for example.

  The main body 3 can accommodate means for driving the end piece 5 in a rotational motion relative to the main body 3.

  This motion is, for example, a rotational motion around the rotation axis X fixed with respect to the main body 3.

  This drive means may comprise an electric motor housed in the main body 3 and is powered by one or more batteries and rotates the end piece around the axis X by means of a gear. The motor can also be driven by a battery or a rechargeable battery.

  In the example shown in FIG. 1, the end piece 5 comprises an upstanding element 4 defining an application surface 30. These upstanding elements are fixed to the base 2 and terminate at the free end 11.

  In the example of FIG. 2, the end piece is in accordance with the present invention. The free end of the application element defines a bevel. The gradient is 10 ° with respect to the base 2. When the end piece is rotated, the shape of the surface changes. The end piece retains its tilted shape but changes direction. The end piece recovers its shape every rotation.

  The end piece has an outer shape (S) that varies when rotated about the axis (X) when viewed from the side in a direction perpendicular to the rotation axis (X).

  In the example of FIG. 3, this end piece follows the prior art. The free end of the application element defines a dome-shaped surface. The surface always maintains this dome shape as the end piece is rotated.

  The end piece has an outer shape (S) that does not vary even when rotated about the axis (X) when viewed from the side in a direction perpendicular to the rotation axis (X).

  In the example of FIG. 4, this end piece follows the prior art. The free end of the application element defines a flat shaped surface. Even when the end piece is rotated, the surface always maintains this flat shape.

  The end piece has an outer shape (S) that does not vary even when rotated about the axis (X) when viewed from the side in a direction perpendicular to the rotation axis (X).

  In the example of FIG. 5, this end piece is in accordance with the invention. This end piece is the same as the end piece of FIG. 2, except that the upstanding elements are spikes rather than bristle bundles. When the end piece is rotated, the outer shape changes.

  6 shows a cross-sectional view of the end piece of FIG. The base 2 is manufactured integrally with the plate 70, and the base 2 is provided with a hook 72 for coupling to a driving member of the coating apparatus. The transfer of motion can also be done in various other ways, for example by making the shapes complementary or by friction.

  FIG. 7 is a top view of the end piece of FIG. This figure shows the free end 11 of the application element.

  8 to 29 should be considered as the following pairs.

Each figure with an even number is a diagram showing the outer shape of the end piece before the end piece is rotated. This profile is referred to as _{S 1.}

Each Figure odd numbers, shows an outer shape _{S 1} and outer _{S 2.} Profile S ₂ represents the outline of the end piece of after a half turn.

Each end piece, we can be seen that is different from the outer shape S ₁ and outer S _2.

  Simply put, the figure shows that the shape has changed after half rotation.

  The end pieces of FIGS. 8 to 29 have an outer shape (S) that varies when rotated about the axis (X) when viewed from the side in a direction perpendicular to the axis (X). These end pieces are end pieces according to the invention.

  In order to use the device according to the invention, it is possible, for example, to apply the composition without rotating the endpiece, and this allows, for example, to spread the composition over the area to be treated. Become. The end piece is then rotated to massage the area where the composition has been applied.

  In another example, the end piece is rotated to massage the area to be treated without dispensing the composition.

  In yet another example, the end piece is rotated to massage the area to be treated without first dispensing the composition.

  The massaging action can cause local heating, for example due to friction of the end piece against the skin, and since the end piece is initially free of composition, it can increase friction and the warmth resulting from the friction.

  The endpiece can then be stopped or the endpiece can be stopped and the composition can be dispensed and spread over the already massaged area while still rotating.

  Throughout the above description, the phrase “comprising” should be considered synonymous with “comprising at least one” unless stated otherwise.
