Description

[0001] The present invention relates to the field of cosmetic product applicators.

[0002] It relates in particular to an application tip suitable for applying a liquid, viscous or pasty cosmetic product to the skin, for example to the eye contour, in particular under the eyes. This document generally envisages an application of a cosmetic product to the skin, without however limiting the invention to this application area.

[0003] In this document, an application tip means the part of an applicator intended to be placed in contact with the skin to apply the cosmetic product.

[0004] Cosmetic products include in this document in particular all products for making up the skin, lips or superficial body appendages. The applicator which is the subject of the present invention is also suitable for the application of care products, in particular liquid and pasty care formulas, intended for application to the skin, lips and superficial body appendages. For simplicity, throughout this document, when reference is made to a cosmetic product, this also includes care products.

[0005] In the remainder of this document, the term “user” obviously refers indifferently to a male or female user.

[0006] Cosmetic products should be applied evenly to the skin, in a thin, even layer. Ideally, the applicator should also allow for a gentle massage of the area where the cosmetic product is applied. A feeling of freshness during application may also be desired.

[0007] Various applicators have been considered for this.

[0008] The most common applicators suitable for applying cosmetic products are the "squeeze tube" type applicators, the "tip applicator rod" type applicators, and the rotating ball applicators often referred to by the English term "roll-on".

[0009] Squeeze tube applicators consist of a flexible tube containing the product to be applied. The tube must be squeezed to cause the product to come out, via an orifice located on a relatively flat, usually metallic, applicator area, in order to provide a sensation of freshness during application. The quantity of product delivered with this type of applicator is imprecise because it depends on the force applied to the tube. In addition, the product is spread using the applicator surface by rubbing it on the skin, which does not allow for a regular film of product to be deposited. Friction during application can also be aggressive or even irritating to the skin.

[0010] Applicators of the "tip applicator" type have a metal rod with a rounded tip. The rod and its tip must be immersed in the cosmetic product so that the tip is covered with the product. The product is applied by rubbing the tip on the user's skin, or by depositing dots of product by repeatedly touching the applicator on the skin. Just like with a squeeze tube type applicator, this does not allow for even application of the product. The friction during application can also be aggressive or even irritating to the skin. In addition, product tends to lodge between the rod and the tip and form a clump that is not applied.

[0011] Finally, "roll-on" applicators generally consist of a flexible tube and a tip with a rotatably mounted ball that loads product onto its inner surface at the tip when the tube is squeezed. The surface of the product-loaded ball is then turned towards the outside of the tip, rolling on the user's skin, to allow the application of the product. This type of applicator does not allow for precise dosing of the applied product, as the tube must be squeezed to load the ball. The quality of the application depends on the orientation of the applicator, with the tip needing to be facing downwards to allow for proper application.

[0012] Ultimately, applicators with a smooth surface, whether used by rubbing or rolling on the skin, do not allow for precise dosing of the quantity of product applied.

[0013] Document FR3013197 presents an applicator whose tip has a revolution shape and ridges. When applying the product, the applicator can be moved into contact with the skin by sliding it over it, possibly with a rotational movement of the application member on itself around an axis parallel to the longitudinal axis of the rod and / or perpendicular to this longitudinal axis. It is therefore up to the user to ensure an adequate application movement, using gestures that are not easy to perform, which does not guarantee regular application of the product.

[0014] Document EP3528660 discloses an applicator for a cosmetic product which comprises a gripping member extending along a longitudinal axis, a rod holder arranged in the gripping member, a rod secured to the rod holder and a cosmetic product application member carried by the rod, the rod holder being mounted to rotate about the longitudinal axis relative to the gripping member. However, this applicator has certain drawbacks. In particular, the application tip is not optimized for the retention of the cosmetic product and a regular release of the cosmetic product during application. Document FR 3 014 656 discloses a cosmetic product applicator according to the preamble of claim 1.

[0015] The present invention aims to provide a tip for applying cosmetic products, including liquid, viscous or pasty care products, allowing regular and continuous application of a precise dose of product to an application area having a defined, potentially relatively large, surface area, while allowing massage of the entire application area. Such an application must preferably be carried out in a simple and ergonomic manner, with gestures that are obvious to the user.

[0016] To this end, the invention relates to a cosmetic product applicator comprising an application tip and a gripping element adapted to be grasped by a user, the application tip comprising branches which extend in a spiral, around a main axis so that they define a cavity having a general shape of revolution around the main axis, the application tip being mounted to rotate freely around the main axis with respect to the gripping element.

[0017] The presence of branches that spiral around a cavity that has a revolution shape, provides several effects and advantages. The cavity forms a space for the retention of the cosmetic product. Its volume can be adapted according to the precise quantity of product that the applicator must retain, corresponding for example to the desired dose for the application of product in a given area, for example under the eyes. Many other application areas are possible, including all areas of the face or neck.

[0018] The configuration of the applicator can, more generally, be adapted to the nature and properties of the product that the application tip is intended to apply. With regard to the nature, or type, of product, a serum must, for example, be applied in a smaller quantity than a cream. The application tip can be configured to retain the correct dose, depending on the product in question. With regard to the properties of the product, for example, an application tip with branches spaced apart is more suitable for a viscous product (in terms of retention and gradual release of the product), while an application tip with branches close together is more suitable for a fluid product.

[0019] The fact that the branches form spirals allows to accompany, to guide naturally, the movement of the user during the application of cosmetic product. The free rotation of the application tip allows it to roll on the skin during application, simply under the effect of the user's gesture. No means, for example electrical, causes the rotation of the applicator tip. In addition, the spiral shape of the branches causes a progressive grip on the skin, without jolts, as the application progresses.

[0020] More specifically, the spiral configuration of each branch means that the branch comes to bear on the skin as and when any rotational movement imposed on the application tip occurs during the application of a cosmetic product. The branches allow a certain grip of the application tip on the skin, and their configuration allows this grip to be regular, whatever the angular position of the applicator during its contact with the skin. There is no jolt caused by the branches during the rotation of the application tip around its main axis, while it is in contact with the skin. Thus, the rotation allows a progressive grip on the skin of each of the branches. The spiral configuration of the branches means that each branch "unrolls" on the skin as the application tip rotates.

[0021] However, thanks to the spiral branches, rolling the applicator tip on the skin can cause alternating pressures on the skin (like "wavelets") promoting blood microcirculation in the application area. The branches thus contribute to the massage effect, the rolling of the applicator with spiral branches, for example helical, causing a slight overpressure whose position changes longitudinally (relative to the applicator) when the application tip rolls on the skin.

[0022] The effect is thus similar to that of a tapping gesture which is recommended when applying a cosmetic product to the eye area. In particular, it is possible to configure the branches so that substantially the same branch area is in contact with the skin throughout the application of a cosmetic product.

[0023] The rotating nature of the application tip improves the consistency of application, prevents the formation of a clump of product, and allows for a regular and gentle application without requiring complex movements on the part of the user. The gestures to be carried out for the application of the product are therefore simple and logical.

[0024] The notions of "spiral" and "spiraling" refer to the fact that the branches rotate around the main axis of the applicator, which defines the longitudinal direction, progressing longitudinally. The spiral formed by the branches can therefore be, in particular, a helix, or a succession of portions of helices, the pitch and / or radius of which are fixed or variable. In practice, a branch forms a turn or a portion of a turn.

[0025] The cavity may be devoid of any internal element. On the contrary, the cavity may comprise a central element, extending along the main axis. A cavity without an internal element makes it possible to maximize the volume for the retention of cosmetic product, and may, in certain embodiments, increase the flexibility of the branches. A central, longitudinal element, passing through the cavity makes it possible to modulate its volume (and therefore modulate the quantity of product retained in the applicator), and may increase the rigidity of the application tip.

[0026] The branches of the application tip can be configured to be more or less flexible or rigid, and consequently more or less transversely deformable. This flexibility is reflected by the flexural modulus of each branch.

[0027] The flexibility of the branches can be adapted in particular by selecting the material from which they are made, and / or by selecting the cross-section of the branches. For example, the flexibility of a branch can depend on its diameter for a branch with a circular cross-section. It depends more generally on the shape and surface area of ​​the cross-section of the branch (which can be constant or change along the branch). This reflects what can generally be referred to as the "thickness" of the branch.

[0028] Adjusting the flexibility or rigidity of the branches allows for a compromise between the massaging effect of the applicator and its ability to release the product it contains. Thus, a rigid branch provides firmer, less cushioned pressure on the skin than a flexible branch. An application tip with flexible branches releases more of the product it contains when applied to the skin and rolled, than an applicator with rigid branches.

[0029] Based on these principles, the same application tip can be equipped with branches of different rigidities, for example by alternating more flexible branches, which will deform during application, and more rigid branches, which will deform less. This makes it possible to combine a significant massage effect with correct distribution of the product during application.

[0030] Similarly, the same branch can be more flexible along one portion of its length and more rigid along another portion.

[0031] The flexibility of the application tip branches can also allow for better adaptation of the applicator to the application areas for which it is intended. For example, for application on the face, this allows the applicator to adapt to the curves present in the preferred application area, or even generally to the curvature of the entire face.

[0032] The cavity may have a so-called bud shape, that is to say an elongated shape of revolution gradually widening and ending in a rounded tip. The cavity may alternatively have a general spherical, cylindrical shape of revolution, pear-shaped, ogive, or any other suitable shape of revolution.

[0033] A bud shape is particularly well suited in that it allows for efficient application of the cosmetic product by holding the applicator in various orientations relative to the application surface, in particular thanks to a wide rounded tip.

[0034] The branches may be devoid of protrusions.

[0035] A protuberance is any prominent projection on the surface of the branch. The branch is notably devoid of teeth or hairs. However, this does not exclude the presence of patterns or local deformations on the surface of the branches, or the presence of a coating, which creates a texture on the surface of the branches. For example, flocking (for example to obtain a "velvet" finish), or a coating based on microparticles, is particularly possible.

[0036] The applicator tip can have exactly three, four, five, six, seven, eight, nine or ten prongs.

[0037] A large number of branches promotes the retention of cosmetic product in the cavity, but makes it more difficult for the product to reach the cavity. A large number of branches also promotes regular rolling of the application tip on the surface of the skin. A small number of branches promotes blood microcirculation in the application area by "tapping" the application area. A small number of branches, in particular because the number of branches conditions the space between two adjacent branches of the application tip, is also associated with less retention and faster and more extensive distribution of the product.

[0038] Each branch can rotate in a spiral around the main axis at an angle of between 90° and 720°, preferably of the order of 180°. Each branch thus forms between a quarter turn and two turns around the main axis of the applicator. A suitable number of turns can be chosen in particular according to the length (longitudinal dimension) of the application tip. The angle of rotation that each branch forms around the main axis gives the branches an angle with respect to the direction of rolling of the application tip on the skin which is not too great to allow good grip on the skin, while being adapted to correctly accompany the movement of the applicator.

[0039] Throughout this document, "approximately" or "in the order of" means the stated value plus or minus 20%.

[0040] The branches of the application tip, and where applicable the other elements of the application tip, may be made of metal, ceramic, wood, glass, or plastic material.

[0041] An applicator tip with metal arms provides a cooling sensation to the user during application. A decongestant effect on the skin can also be achieved. This also gives the applicator tip an aesthetic appearance. A metal or ceramic tip is generally perceived as a high-quality object by the user. A tip made of wood, or other natural material, can be obtained in an environmentally friendly manner and does not present any recycling issues. The use of plastic facilitates manufacturing and limits the cost of the applicator tip.

[0042] Each branch may have a raised or hollow texture on the surface, which increases its roughness. This texture can be obtained by forming a pattern on the surface of the branches, which allows for better grip on the skin and better retention of the cosmetic product. Better grip on the skin limits the slippage of the application tip and facilitates the adoption of a suitable application technique. The pattern can be formed directly during the manufacture of the applicator (by additive synthesis, for example), it can be engraved, it can be obtained by applying a coating to the surface of the applicator (for example by flocking), or in any other appropriate manner.

[0043] Each temple may have a surface coating, for example a metallic coating or an elastomeric coating. A metallic coating, for example by vapor deposition, gives the temples a metallic appearance and feel. An elastomeric coating provides better grip on the skin and offers a soft feeling upon contact with the skin. Any other coating offering a particular effect in terms of interaction between the skin and the applicator can be considered. In particular, a varnish, a varnish loaded with particles, flocking, etc.

[0044] The applicator may further comprise a longitudinal rigid rod connecting the gripping element to the application tip.

[0045] In particular, the applicator may comprise a rigid cylindrical core extending along the main axis, said core being rigidly fixed to the gripping element or formed in one piece with the gripping element, the rod being hollow and mounted free to rotate but fixed in translation on the core, the application tip being rigidly connected to the rod or formed in one piece with the rod, and the core extending in the hollow rod over the entire length of the rod measured in the direction of the main axis, with the possible exception of a connection zone between the rod and the application tip.

[0046] This configuration provides good transverse rigidity to the applicator, which allows for effective massage during application. The risk of clogging the mechanism allowing the rotation of the application tip by cosmetic product is also reduced.

[0047] The rod may be made of metal or ceramic, or coated with a metal or ceramic coating. In particular, a rod made of the same material as the application tip or having the same appearance makes it possible to form a very aesthetic applicator.

[0048] The invention also relates to an assembly comprising a bottle and an applicator as defined above, in which the bottle contains the cosmetic product, the bottle comprising a neck adapted to be closed by the gripping element, so that, when the bottle is closed by said gripping element, the application tip is in contact with the cosmetic product.

[0049] In the attached drawings, given as non-limiting examples: there figure 1 is a three-dimensional schematic view of a cosmetic product applicator according to one embodiment of the invention; figure 2 is a three-dimensional schematic view of an application tip that can be used in one embodiment of the invention; figure 3 is a three-dimensional schematic view of another application tip that can be used in one embodiment of the invention; figure 4 is a three-dimensional schematic view of another application tip that can be used in one embodiment of the invention; figure 5 is a sectional view of an assembly comprising the applicator according to one embodiment of the invention and a bottle of cosmetic product.

[0050] There figure 1 represents a cosmetic product applicator 1 according to one embodiment of the invention. This applicator 1 comprises a gripping element 2 that the user grasps by hand when he wishes to apply the cosmetic product.

[0051] The applicator extends in a general direction of extension, around a main axis A. The general direction of extension of the applicator is said to be longitudinal.

[0052] The applicator 1 comprises an application tip 3. The application tip 3 corresponds to the part of the applicator intended to be loaded with cosmetic product and to be placed in contact with the skin in order to transfer the cosmetic product thereto.

[0053] In the exemplary embodiment shown here, the application tip 3 is mounted at the end of a rod 4 which extends along the main axis A and connects the gripping element 2 to the application tip 3.

[0054] According to the present invention, the application tip 3 is mounted freely rotatably, around the axis A, with respect to the gripping element 2. In the configuration shown, at least two solutions can thus be implemented: either the tip is mounted rotatably with respect to the rod 4, which can then be fixed with respect to the gripping element 2, or the application tip 3 and the rod 4 are fixed with respect to each other (for example in one piece) and the rod 4 is mounted rotatably with respect to the gripping element. An embodiment according to this second possibility is described by way of example in more detail with reference to the figure 5 .

[0055] There figure 2 shows in more detail the application tip 3 of the applicator 1 of the figure 1 .

[0056] The application tip 3 is formed around the main axis A, and has a general shape of revolution. More particularly, the application tip comprises branches 31 which spiral around the main axis A, and thus define a cavity 32 internal to the application tip. The cavity 32 has a shape of revolution around the main axis A.

[0057] The application tip 3 can thus be considered, in general, as a hollow tip.

[0058] Each branch 31 rotates, spiraling around the main axis A; at an angle of between 90° and 720°, preferably of the order of 180°. Each branch thus forms, between its ends, between a quarter turn and two turns around the main axis of the applicator.

[0059] Each branch can thus, for example, form a portion of a helix around the main axis A.

[0060] The application tip 3 advantageously comprises at least three branches 31. The application tip can thus comprise exactly three, four, five, six, seven, eight, nine, or ten branches.

[0061] The branches 31 can be made of various materials. They can be metallic, for example stainless steel. They can be ceramic. They can be plastic. They can be wood, or other suitable natural material.

[0062] The surface of the branches is advantageously free of protrusions. A protrusion is understood to mean an element that significantly projects from the surface of the branches. Thus, the branches advantageously do not have teeth or bristles. However, this does not exclude the presence of undulation or local deformations to improve the massage effect during the application of the cosmetic product. Furthermore, this does not exclude the presence of a slightly raised (or hollow) texture on the surface of the branches, to improve the retention of the cosmetic product by the application tip 3 and / or improve the grip on the skin during the application of the cosmetic product. This texture can be generated directly in the material forming the branches (by machining, or obtained directly during the manufacture of the applicator) or by applying a coating to the branches.

[0063] The branches 31 may also be covered with a coating, for example a metallic coating which improves the appearance of the application tip and, if appropriate, the sensation of freshness during application. A coating by vapor deposition may be carried out.

[0064] The temples may alternatively be covered with a coating of elastomeric material. This includes any polymer with elastic properties, including organic polymers, such as rubbers, and mineral polymers such as silicones. This coating may be overmolded onto the temples 31. An elastomeric coating is soft and supple to the touch and improves grip on the skin.

[0065] A flock coating is also possible, in particular to obtain a “velvet” effect.

[0066] The branches preferably have a rounded section. The cross-section of the branches 31 can thus be circular, oval, or even square or triangular with rounded corners.

[0067] In the embodiment shown, the application tip 3 (and the corresponding cavity 32) has a so-called “bud” shape of revolution. A bud shape designates an elongated shape of revolution which gradually widens and ends in a rounded tip 33.

[0068] Any form of revolution can nevertheless be envisaged for the application tip within the framework of the present invention.

[0069] In particular, a pear shape, an oval rugby ball shape, or a cylindrical shape are possible. Furthermore, the main body can gradually narrow, so as to present, for example, an ogive shape.

[0070] The branches 31 are advantageously distributed radially in a regular manner around the main axis A. We can speak of a distribution according to a radial symmetry. In other words in any cross section of the application tip, each branch is at the same distance from the two branches which surround it (or are diametrically opposed if there are only two branches).

[0071] In an applicator according to the present invention, the cavity 32 constitutes a volume suitable for receiving cosmetic product and retaining it. The cavity 32 thus constitutes a reserve of cosmetic product, which will be released, through the spaces present between the branches 31, during the application of the cosmetic product.

[0072] The volume of the cavity can thus be adapted to the desired volume of cosmetic product for application to a defined area of ​​the body. It may be advantageous, for example, to ensure that the application tip is loaded with a suitable quantity of cosmetic product (sufficient but not excessive) for application to the surface to be treated. For example, the applicator may be adapted to allow application to the surface under one eye, or possibly to the surface under both eyes (in this case the product may be, but is not limited to, a cream or serum for dark circles). The applicator may be adapted to apply to the surface of one cheek or both cheeks. The applicator may be adapted to allow application of a product to the entire surface of the face and / or neck.

[0073] Of course, the above examples are not exhaustive, and the applicator can be adapted to any particular skin surface.

[0074] The shape and dimensions of the application tip 3 can be adapted accordingly.

[0075] While the cavity of the application tip of the figure 2 is devoid of any internal element, the cavity 32 of the application tip of the figure 3 comprises a central element, namely an elongated central element 34, extending along the main axis A.

[0076] The elongated central element 34 is here cylindrical, but any other suitable shape can be used.

[0077] The elongated central element 34 connects a proximal tip 35 of the application tip 3 which allows its connection to the rod 4 at the end 33 of the application tip.

[0078] The elongated central element 34 may be formed from the same material as the branches 31. In particular, it may be in one piece with the branches 31.

[0079] The elongated central element 34 can have several functions. It can allow the volume of the cavity 32 to be adapted, independently of the external shape of the application tip 3.

[0080] It can make it possible to stiffen the application tip, by maintaining constant the distance between the proximal tip 35 and the end 33, or even their relative position.

[0081] There figure 4 represents another example of a tip in which the cavity 32 of the application tip of the figure 3 comprises a central element in the form of a bulb 36. The bulb 36 is connected to the proximal tip 35 of the application tip 3, without however connecting it to the end 33. The bulb 36 thus makes it possible to modulate the volume available to receive the product in the applicator, without however influencing the capacity to deform during application, and more generally on the mechanical properties that the applicator would have in the absence of this bulb 36.

[0082] There figure 5 represents, according to a schematic sectional view, an assembly comprising a bottle 5 and the applicator 1 of the figure 1 . The gripping element 2 also forms here a cap adapted to be screwed onto the bottle 5 of cosmetic product which has a suitable neck 51. For this purpose, the cap can be provided with a thread. According to other embodiments, the cap could be adapted to be attached to the bottle by clipping.

[0083] In the exemplary embodiment of the figure 5 , the application tip 3 is rigidly fixed to the rod 4. The rod 4 is hollow, and mounted freely rotatably on a rigid and longitudinal core 6, which is rigidly fixed to the gripping element 2.

[0084] The rod 4 is on the other hand fixed in translation along the core 6.

[0085] The bottle 5 forms an internal volume containing a cosmetic product, liquid, viscous, or pasty, for example semi-liquid.

[0086] When the applicator 1 is attached to the bottle 5 (the gripping element 2 forming a suitable cap), the application tip 3 is in contact with the cosmetic product. For example, the application tip 3 is immersed in the cosmetic product. The application tip 3 is thus loaded with cosmetic product, on its surface and in the cavity 32.

[0087] The bottle 5 comprises a wringer 7. The wringer 7 is a flexible device located near the neck 51 of the bottle 5 or in it. The wringer 7 provides a calibrated passage for the insertion and removal of the application tip 3. The wringer 7 makes it possible to remove excess cosmetic product from the surface of the application tip 3 when it is removed from the bottle 5. The dose of cosmetic product, essentially defined by the volume of the cavity 32, is thus perfectly respected. A predetermined, precise, regular and optimal quantity of cosmetic product, for application to a given area of ​​the user's body, is thus contained in and on the application tip 3.

[0088] The wringer 7 may be of the so-called “returning wringer” type. Such a wringer 7 has a truncated cone shape and tends to turn over when the application tip 3 passes.

[0089] The cosmetic product applicator, including a skincare product applicator proposed in the invention, comprising a hollow application tip with spiral branches mounted to rotate, allows for regular application, in a regular film, of a precise quantity of product throughout the rotation of the application tip on the user's skin. The branches of the application tip accompany the application movement, which causes the tip to rotate by rolling on the application surface (typically the skin), and provide regular, smooth grip on the user's skin. They also promote the massage effect during application of the product.
