ROTATING APPLICATOR FOR COSMETIC PRODUCT

Description

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

[0002] It relates in particular to an applicator adapted for applying a liquid, viscous, or pasty cosmetic product to the skin, for example, around the eyes, especially under the eyes. This document generally considers the application of a cosmetic product to the skin, but does not limit the invention to this area of ​​application.

[0003] Cosmetic products, as defined in this document, include all products for applying makeup to the skin, lips, or hair and nails. The applicator described in this invention is also suitable for applying skincare products, including liquid and paste formulas, intended for application to the skin, lips, and hair and nails. For simplicity, throughout this document, any reference to a cosmetic product includes skincare products.

[0004] In the remainder of this document, the term "user" obviously refers to both a male and a female user.

[0005] Cosmetic products should be applied evenly to the skin in a thin, uniform layer. Ideally, the applicator should also allow for a light massage of the application area. A cooling sensation upon application is also desirable.

[0006] Various applicators were considered for this purpose.

[0007] The most common applicators that are suitable for applying cosmetic products are the "squeezed tube" type applicators, the "rod with applicator tip" type applicators, and the rotating ball applicators often referred to by the English expression "roll-on".

[0008] Squeeze tube applicators consist of a flexible tube containing the product. The tube must be squeezed to dispense the product through an opening located on a relatively flat, usually metallic, applicator surface, providing a cooling sensation upon application. The amount of product dispensed with this type of applicator is imprecise because it depends on the force applied to the tube. Furthermore, spreading the product using the applicator surface involves rubbing it against the skin, which does not allow for an even film of product. This rubbing during application can also be harsh or even irritating to the skin.

[0009] Applicators of the "stem with applicator tip" type consist of a metal stem with a rounded tip. The stem and tip must be dipped into the cosmetic product so that the tip becomes coated. The product is applied by rubbing the tip against the user's skin or by depositing dots of product through repeated contact of the applicator. As with a squeeze tube applicator, this does not allow for even application. The friction during application can also be harsh or even irritating to the skin. Furthermore, product tends to accumulate between the stem and the tip, forming a clump that is not applied.

[0010] Finally, roll-on applicators generally consist of a flexible tube and a nozzle with a rotating ball that picks up product on its inner surface when the tube is squeezed. The product-laden surface of the ball then faces outward, rolling over the user's skin to apply the product. This type of applicator does not allow for precise dispensing, as the tube must be squeezed to load the ball. The quality of the application depends on the applicator's orientation; the nozzle should be pointing downwards for optimal application. Furthermore, this type of applicator is prone to clogging: cosmetic product can block the passage between the tube and the ball, preventing it from rolling freely or even preventing the product from dispensing.

[0011] Document FR3013197 describes an applicator with a rotary tip featuring grooves. During product application, the applicator can be moved along the skin by gliding it, possibly with a rotational movement of the applicator itself around an axis parallel to the longitudinal axis of the stem and / or perpendicular to this longitudinal axis. Therefore, the user must perform the application correctly, using a technique that is not easy to master, which does not guarantee even application of the product.

[0012] Document EP3528660 discloses a cosmetic product applicator comprising a gripping member extending along a longitudinal axis, a stem holder within the gripping member, a stem attached to the stem holder, and a cosmetic product application member carried by the stem. The stem holder is mounted to rotate freely around the longitudinal axis relative to the gripping member. However, this applicator has some drawbacks. Firstly, the product is likely to pass between the stem and the gripping member, which can impede the stem's rotation and lead to product loss. Furthermore, the applicator's configuration makes it unsuitable for massage during application, as lateral force on the tip (application member) can bend the stem and easily damage the rotational connection between the stem holder and the application member.

[0013] Document EP1593320 discloses a cosmetic product applicator having a hollow stem and a core. The core is rotatably mounted inside the stem.

[0014] The present invention aims to provide a cosmetic product applicator, including for skincare products, whether liquid, viscous, or paste-like, allowing for the regular and continuous application of a precise dose of product to a defined application area, while also enabling massage of the entire application area. Such application should preferably be simple and ergonomic, with intuitive gestures for the user.

[0015] To this end, the invention relates to a cosmetic product applicator comprising a gripping element adapted to be grasped by a user and an application tip having a shape whose outer shell is of revolution. The applicator also comprises a rigid cylindrical core extending in a longitudinal direction, said core being rigidly fixed to the gripping element or formed as a single unit with the gripping element, and a hollow stem mounted freely for rotation but fixed against translation on the core, the hollow stem extending longitudinally from the gripping element to the application tip. The application tip is rigidly connected to the hollow stem or formed as a single unit with the hollow stem. The core extends within the hollow stem along the entire length of the hollow stem measured in the longitudinal direction, with the possible exception of a connection zone between the hollow stem and the application tip.

[0016] The invention thus proposes a cosmetic product applicator in which the application tip rotates relative to the applicator's gripping element, allowing for easy and even application of the cosmetic product. Thanks to the configuration of the applicator of the present invention, applying a tangential force to the application tip, thereby massaging the application area, does not cause significant deformation of the applicator, and in particular, no significant bending of the core and the hollow stem. Furthermore, the rotation mechanism, employing a core that extends along the entire or nearly the entire length of the hollow stem mounted to rotate on the core, allows the application of such a tangential massaging force to the tip without affecting the rotation mechanism. Finally, the risk of the rotation mechanism becoming clogged with cosmetic product is eliminated.

[0017] The core can be metallic. Any other suitable rigid material may be used alternatively. Rigidity is defined as sufficient flexural strength to withstand radial force exerted on the applicator tip during cosmetic product application, without excessive deflection that would impair the free rotation of the tip and stem. The applicator tip may be metallic or ceramic. The hollow stem may be metallic. The hollow stem and / or the applicator tip may be made of plastic with a metallic coating on one outer surface. In this case, the hollow stem may have a plastic body covered by a metallic sleeve.

[0018] Various material combinations are possible. The use of a metal or ceramic applicator tip is preferred. A metal applicator tip provides a cooling sensation to the user during application. Furthermore, an applicator with an identical applicator tip and hollow stem, preferably metallic, such as chrome-plated, is perceived as a high-quality product.

[0019] The hollow rod may have a perforated inner surface so as to limit the contact areas between said hollow rod and the core.

[0020] The applicator may include a first rotational guide element and a second rotational guide element, the first rotational guide element being interposed between the core and the hollow rod at a first end of the hollow rod, and the second rotational guide element being interposed between the core and the hollow rod at a second end of the hollow rod.

[0021] The first rotational guide element and the second rotational guide element can be bearings made of plastic material, ceramic or metal such as copper or copper alloy.

[0022] The first rotational guide element and the second rotational guide element can be bearings.

[0023] The applicator may include a single rotating guide element interposed between the core and the hollow rod. Advantageously, the rotating guide element extends along the entire length, or at least a majority of the length, of the hollow rod.

[0024] The rotational guides limit the contact area between the core and the hollow rod, thereby reducing friction that could impede the rotation of the hollow rod and the application tip. They also ensure the longitudinal alignment of the contact points between the core and the hollow rod, improving the mechanism's ability to function correctly despite the tangential force applied to the application tip. Finally, they reduce noise during the relative rotation of the core and the hollow rod, particularly when both the core and the hollow rod are metallic.

[0025] The core may include a proximal end of the gripping element and an opposite distal end, the hollow stem and the application tip being locked in translation relative to the core at said distal end of the core.

[0026] This optimizes the translational blocking of the hollow rod, which is interposed between the distal end of the core and the gripping element of the applicator.

[0027] The application tip may have raised patterns on its surface, preferably helical.

[0028] Embossed patterns can be any type of texture or raised design. Helical patterns, in particular, can be ridges or grooves. They allow for better product retention on the applicator tip and enable the applicator to gradually adhere to the user's skin as the product is applied. These patterns thus guide and support the user's movements during the application of the cosmetic product.

[0029] The gripping element can form a cap adapted to seal the neck of a corresponding bottle. The gripping element can comprise an internal structure and an external structure that covers said internal structure, the internal structure (23) comprising a longitudinal channel in which the core is inserted and fixed.

[0030] The applicator that is the subject of the present invention is thus particularly suitable for use with a bottle of which it serves as a cap.

[0031] 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 having a neck adapted to be closed by the cap formed by the gripping element, so that, when the bottle is closed by said cap, the application tip is in contact with the cosmetic product.

[0032] The bottle may include a wiper, the wiper allowing the application tip to be wiped during its passage, so that a defined quantity of product is carried by the application tip after the applicator is extracted from the bottle.

[0033] This allows the application tip to be loaded with a precise, optimal and consistent amount of product to be applied to a given area of ​​the user (for example, under an eye).

[0034] The attached drawings are given as non-exhaustive examples: there figure 1 is a schematic cross-sectional view of a cosmetic product applicator according to an embodiment of the invention; the figure 2 is a schematic cross-sectional view of an assembly comprising a cosmetic product bottle and a cosmetic product applicator according to an embodiment of the invention; the figure 3 is a schematic exploded view, in three dimensions, of an assembly comprising a cosmetic product bottle and a cosmetic product applicator according to an embodiment of the invention; the figure 4 is a schematic cross-sectional view of a cosmetic product applicator according to a second embodiment of the invention; the figure 5 is a schematic cross-sectional view of a cosmetic product applicator according to a third embodiment of the invention.

[0035] There figure 1 represents a cosmetic product applicator 1 according to an embodiment of the invention. This applicator 1 comprises a gripping element 2, here formed by a cap adapted to be screwed onto a cosmetic product bottle having a suitable neck. To this end, the cap may be provided with a thread 21. According to other embodiments, the cap could be adapted to be attached to the bottle by clipping.

[0036] The gripping element 2 is adapted to be grasped by hand by a user wishing to use the applicator.

[0037] The applicator extends in a general direction of extension, around an axis A. The general direction of extension of the applicator is said to be longitudinal.

[0038] The applicator comprises a core 3, which extends longitudinally along axis A. The core 3 is cylindrical. It can be made of metal or plastic. In a preferred embodiment, the core 3 is metallic to provide high rigidity. The core 3 thus generally resembles an elongated cylindrical rod, long relative to its diameter.

[0039] The web 3 is straight and has a proximal end 31 opposite the gripping element 2 and a distal end 32 opposite the proximal end 31. The web 3 is rigidly fixed to the gripping element 2 at its proximal end. In particular, the proximal end and a portion of the web 3 are fixed in a longitudinal channel 22 of the gripping element 2. This fixing can be achieved in various ways, by press fitting, gluing, brazing, screwing, and / or with the aid of a fixing element (not shown in the figure). figure 1 , but visible at the figure 3 ).

[0040] Alternatively, the core 3 can be formed as a single piece, in one piece, with all or part of the gripping element.

[0041] In the example shown, the gripping element 2 is formed in two parts: an internal structure 23 and an external structure 24. The external structure 24 corresponds to the visible part of the gripping element, which can be grasped by the user and may serve an aesthetic purpose. The internal structure 23 forms, in the example shown, the thread 21 and includes the longitudinal channel 22 in which the core 3 is fixed. Alternatively, the internal structure 23 and the external structure 24 can be formed as a single unit.

[0042] Applicator 1 has the distinctive feature of comprising a hollow rod 4. The hollow rod 4 is longitudinal and straight. It is mounted freely for rotation on the web 3. However, it is fixed in translation along the web 3.

[0043] An application tip 5 is rigidly fixed, without any degree of freedom, to one end of the hollow rod 4. This fixing can be achieved by press fitting, bonding, brazing, or any other suitable fastening method. Alternatively, the application tip 5 can be formed as a single unit with the hollow rod 4.

[0044] The application tip 5 is thus free to rotate, together with the hollow rod 4, around the core 3.

[0045] The applicator tip 5 is advantageously made of metal or ceramic. This provides a cooling sensation upon contact with the user's skin. A decongesting effect on the skin can also be achieved. This also gives the tip an aesthetically pleasing appearance. A metal or ceramic tip is generally perceived by the user as a high-quality item.

[0046] Alternatively, a tip made of plastic material, covered with a metallic or ceramic coating, can be used.

[0047] The hollow rod 4 can also be metallic. Alternatively, it can be made of plastic material covered with a coating, preferably metallic. The metallic coating can then be formed by a metallic deposit (for example, a vacuum deposition, a physical or chemical vapor deposition) or by a metallic sleeve covering a plastic body of the hollow rod 4.

[0048] The tip and the hollow stem advantageously have the same surface appearance, for example metallic and shiny, like a chrome look.

[0049] The applicator tip has a general shape of revolution, meaning that the outer shell of its three-dimensional form is of revolution, allowing the tip to roll smoothly over the user's skin during application of the cosmetic product, as described below. The outer shell of the applicator tip's shape therefore corresponds to the three-dimensional geometric form that approximates the tip's shape, without taking into account any local deformations or patterns on the surface. This is the general shape of the applicator tip as it is spontaneously perceived. The tip may, however, have raised features on its surface, such as ridges, grooves, ridges, or flutes. These raised features on the tip's surface can serve to improve product retention on the tip, as well as to enhance the tip's smooth rolling action on the skin.The ridges, grooves, ridges, or flutes are thus advantageously longitudinal or helical around axis A. A helical shape is preferred because it provides a gradual, smooth grip on the skin during application. Similarly, the applicator tip surface can have a texture that, by increasing surface roughness, improves the retention of the cosmetic product on the tip.

[0050] The translational locking of the hollow rod 4 relative to the core 3 is achieved, in one direction, at the distal end 32 of the core 3. This locking can be achieved by means of a flared end at the distal end of the core 3, or by an added component at said distal end of the core. This locking prevents the hollow rod 4 from being moved away from the gripping element 2. The end piece and / or the gripping element prevents translation in the opposite direction.

[0051] The core 3 extends into the hollow rod 4 along its entire length, with the possible exception of the connection area 6 between the hollow rod 4 and the application tip 5. In other words, the core 3 extends to the application tip 5, with a functional clearance if necessary.

[0052] To apply a cosmetic product, the user grasps the applicator by the gripping element 2, and, the tip having been previously loaded with cosmetic product, the user rolls it over their skin. The application is therefore carried out, intuitively, in a substantially transverse direction, that is to say perpendicular to the longitudinal direction of the axis A of the applicator.

[0053] Rolling the applicator across the skin, combined with the force applied laterally, provides a gentle massage to the application area. This lateral force also contributes to the application of a thin, even film of cosmetic product.

[0054] The application of a relatively large transverse force is possible, despite the applicator's elongated shape, for several reasons. First, the applicator's structure, with a rigid longitudinal core extending to the application tip and a hollow rod mounted on the longitudinal core, provides the applicator with high rigidity. Furthermore, the fact that the core extends along almost the entire length of the hollow rod allows the hollow rod and application tip to be guided in rotation at longitudinally distant points: rotational guidance can be achieved at both ends of the hollow rod. This limits the risk of the rotation mechanism jamming due to the transverse force applied at the application tip.

[0055] Rolling the applicator tip on the skin allows for the complete application of the product carried on the tip. The amount of product carried by the tip can be precisely calibrated by the tip's configuration.

[0056] There figure 2 represents a set comprising a bottle 7 of cosmetic product and the applicator 1 of the figure 1 The bottle 7 forms an internal volume 71 containing a cosmetic product 8, which may be liquid, viscous, or pasty, for example, semi-liquid. The bottle has a threaded neck 72. In the example shown, the threading is achieved by attaching a threaded ring 73 to the neck of the bottle 2.

[0057] When the applicator 1 is screwed onto the bottle 7 (the gripping element 2 forming a suitable cap), the application tip 5 is in contact with the cosmetic product 8. For example, the application tip 5 is immersed in the cosmetic product 8. The application tip 5 thus becomes loaded with cosmetic product, on its surface and / or in one or more cavities formed by the application tip 5.

[0058] Bottle 7 includes a wiper 9. The wiper 9 is a flexible device located near or within the neck 72. The wiper 9 provides a calibrated passage for the insertion and removal of the applicator tip 5. The wiper 9 primarily removes excess cosmetic product from the applicator tip 5 when it is removed from bottle 7. Thus, each time it is removed from bottle 7, the applicator tip 5 is loaded with a precise amount of cosmetic product. Depending on the configuration of the application nozzle 5 (in particular the area of ​​its external surface, the volumes and cavities created by the patterns it carries, etc.) and depending on the configuration of the nozzle and the physico-chemical properties of the cosmetic product 8, the application nozzle 5 is loaded after passing through the wringer 9 with a predetermined, precise, regular and optimal quantity of cosmetic product for application to a given area of ​​the user's body.For example, the applicator can be loaded with a predetermined, precise, regular and optimal dose of cosmetic product for application under or around an eye.

[0059] The term "wringer" is used because this type of device is generally used with a flexible application nozzle that it allows to be wrung out. In the context of the present invention, the application nozzle is preferably rigid and does not deform during normal use.

[0060] The wringer 9 can be of the so-called "reversing wringer." Such a wringer 9 has a truncated cone shape and tends to reverse itself as the application nozzle 5 passes over it. A reversing wringer allows for the wringing, or wiping, of items with two different diameters. In this case, the wringer 9 allows for the wringing of the outer surface of the hollow stem 4 on one hand and the application nozzle 5 on the other. Thus, the applicator stem is always perfectly clean, without any residual cosmetic product on its surface.

[0061] The wringer may also advantageously include an orifice for equalizing the pressure between the internal volume 71 of the bottle 7 and the outside of said bottle (i.e., the atmosphere, or ambient air). This avoids creating mechanical resistance when removing the applicator 1 from the bottle 7, or when inserting the applicator 1 into the bottle 7, and prevents the generation of a Venturi effect when removing the applicator 1 from the bottle 7.

[0062] It is also noteworthy that the rotating mechanism of the nozzle and the shaft is particularly well protected against clogging by cosmetic product. Indeed, the connection area 6 between the hollow shaft 4 and the application nozzle 5 is advantageously completely sealed against cosmetic product. The only possible area of ​​infiltration is therefore at the end of the hollow shaft located in the immediate vicinity of the gripping element. A seal can be provided in this area, although it is unlikely that this area will be reached by product, due to its distance from the application nozzle 5, and thanks to the wiper 9 which allows, if necessary, the hollow shaft 4 to be cleaned.

[0063] There figure 3 represents an assembly comprising a bottle 7 of cosmetic product and an applicator 1 according to an embodiment of the invention.

[0064] Thus, we find, represented on the figure 3 , in addition to the bottle 7, the gripping element 2 comprising an internal structure 23 and an external structure 24, the hollow stem 4, the core 3, and the tip 5.

[0065] The core 3 is fixed by a tight fit into the internal structure 24 of the gripping element 2. Other alternative or complementary fixing methods may be used. For example, a fixing element may be screwed or crimped onto the core 3, at its proximal end 31, in order to fix the core 3 to the gripping element 2.

[0066] The embodiment of the invention shown in the figure 3 is also remarkable in that the applicator further comprises a first rotational guide member 43 and a second rotational guide member 44. The first rotational guide member 43 is interposed between the core 3 and the hollow rod 4 at a first end 41 of the hollow rod 4. The second rotational guide member 44 is interposed between the core 3 and the hollow rod 4 at a second end 42 of the hollow rod 4.

[0067] Each of the first rotational guide members 43 and the second rotational guide members 44 can be formed from a bearing or a bushing. One of the first rotational guide members 43 and the second rotational guide members 44 can be a bearing while the other is a bushing.

[0068] Alternatively, a single rotating guide element can be used. In this case, the guide element is long enough to distribute the transverse forces exerted on the application nozzle over a sufficient length of the hollow rod 4. For example, the guide element can extend over the entire or nearly the entire length of the hollow rod 4.

[0069] Furthermore, in the absence of a rotational guide, the hollow rod 4 can have a perforated inner surface, i.e., one with hollowed-out sections. This limits the contact areas between the hollow rod 4 and the web 3. Friction is thus reduced, rotation is freer, and any noise related to rotation is limited.

[0070] In particular, a plastic bearing, ensuring low friction, can be used. The plastics used may include, but are not limited to, Polytetrafluoroethylene (PTFE), PTFE-filled plastic, Polyetheretherketone (PEEK), Polyphenylene Sulfide (PSS), nylon, acetal, and polyester.

[0071] The rotational guide elements limit the contact area between the core 3 and the hollow rod 4, which facilitates the rotation of the latter.

[0072] The rotational guide elements also ensure the longitudinal position of the contact areas between the core 3 and the hollow rod 4.

[0073] Finally, the rotational guide elements help to limit the noise during the relative rotation between the web 3 and the hollow rod 4. Indeed, a slight noise can occur when the contact surfaces are large and / or when the web 3 and the hollow rod 4 are both metallic, so that a "metal on metal" friction occurs during the rotation of the hollow rod 4.

[0074] Furthermore, although the applicator of the figure 1 and that of the figure 3 While these components are presented as assemblies of various elements formed independently, it is alternatively possible to manufacture several of these elements together using additive manufacturing. This reduces the number of assemblies required and allows for the direct production of complex, small assemblies. Specifically, the core, the hollow rod, and the application tip can be formed together using additive manufacturing. This directly produces a subassembly comprising the hollow rod and the application tip, which are free to rotate around the core but fixed in translation along it. The gripping element can also be obtained, in whole or in part (for example, only the internal structure), in conjunction with the aforementioned elements.

[0075] Numerous application tip shapes are conceivable within the scope of the invention. figures 1 à 3 show an applicator 1 having a tip in the shape of a so-called bud, that is to say an elongated revolution shape gradually widening and ending with a rounded tip.

[0076] There figure 4 and the figure 5 present alternative embodiments of applicators according to the present invention, in which the application tips 5 have other shapes.

[0077] To the figure 4 , the application tip 5 has a generally spherical shape.

[0078] To the figure 5 , the application tip 5 has a general rugby ball shape.

[0079] The cosmetic product applicator, including skincare product applicators, developed according to the invention allows for the even application of a precise amount of product in a thin, uniform film throughout its rotation on the user's skin. The rotating nature of the applicator improves the evenness of the application, prevents the formation of product buildup, and allows for a smooth and even application without requiring complex movements from the user. The application technique is thus simple and intuitive. Due to its design, the cosmetic product applicator allows for the application of a transverse force, enabling a massage of the application area, without significantly deforming the applicator or affecting or damaging the rotation mechanism.When the applicator tip has raised features, particularly helical ones, rolling it across the skin can create alternating pressure (like "ripples") that promotes microcirculation in the application area. This effect is similar to the tapping motion recommended when applying cosmetic products to the eye area. In some designs, the applicator provides a cooling sensation and can have a decongesting effect on the skin. Finally, the risk of the applicator becoming clogged with cosmetic product is reduced.
