Description

Title of the invention: Device for applying a solid cosmetic product Technical field of the invention

[0001] The invention relates to a device for applying a solid cosmetic product, in particular a cosmetic product grape. For example, the grape consists of a solid perfume.

[0002] This device mainly comprises a product storage case and a product application assembly, which is separate from the storage case, and which is mounted inside the storage case. Technical background

[0003] The prior art of application devices used for packaging a cosmetic product, such as a cosmetic product stick, particularly but not exclusively for a lipstick stick, or a solid perfume stick, is known. Such a cosmetic product stick is sometimes referred to as a "grape".

[0004] Application devices generally include a case that encloses a product application kit. The case and the application kit are two separate sub-assemblies, removable from one another. They can be nested together when the user wishes to close the device for easy transport or storage in a toiletry bag, and they can be separated so that the user can use the application kit to apply the cosmetic product to their body.

[0005] This application assembly includes a mechanism that can be controlled to slide the grape between a retracted position in which it is protected by the mechanism, and a deployed position in which at least one section of the grape protrudes from the mechanism to allow its application.

[0006] The packaging plays a major aesthetic role. Cosmetic product packaging is perceived by the user as an indicator of the product's market value, so a case of a certain weight and aesthetic appeal will be associated with a perceived value. The same applies to the application unit, at least the part visible from the outside when the application device is closed. More generally, all parts of the application device visible from the outside must have a pleasing aesthetic.

[0007] For this purpose, to guarantee their aesthetic appeal, it is customary to provide them with a galvanized outer coating increasing the perceived value.

[0008] However, such a galvanized outer coating is expensive.

[0009] It is alternatively or cumulatively possible to add one or more decorative coverings, such as fabric that wraps around the case, or rhinestones, or the like. To ensure that such a decorative covering is securely attached, for example by gluing or clipping, the covering must be pressed against the case body with considerable force, thus creating a risk of deformation of the case body, which is undesirable. Summary of the invention

[0010] The present invention aims to overcome the various disadvantages stated above, by means of a device for applying a solid cosmetic product, the external parts of which are visible to the user and are coated to give the device a certain aesthetic appeal, all at a lower cost and without risk of deformation.

[0011] According to the invention, the application device for a solid cosmetic product, in particular a cosmetic product applicator, extends along a central axis X and comprises:

[0012] - a product storage case comprising: • a hollow body formed by a peripheral wall delimiting a cavity opening on one side into an open upper end and on the other side into an open lower end; • a head insert located at the upper end of the body; • a bottom insert located at the lower end of the body; • at least one decorative covering fixed to the peripheral wall of the body;

[0013] - a product application assembly, which is separate from the storage case, and which is mounted inside the body cavity in a removable manner.

[0014] This device is characterized primarily in that the storage case comprises a structure developing inside the cavity and made of the same material as the body, said structure having means for receiving the application assembly as well as means for mechanically reinforcing the body.

[0015] The main idea of ​​this invention is to provide a structure within the case body to stiffen the body and prevent any deformation of the body when the decorative coating is attached. This structure also accommodates the application assembly when the user closes the device, ensuring that it is correctly positioned and held securely. The structure thus performs several functions. Furthermore, it is made of the same material as the body, which reduces the number of parts required for assembly.

[0016] According to the different embodiments of the invention, which may be considered together or separately: - said receiving means consist of a central sleeve developing along the extension direction of the body corresponding to the X axis, and into which the application assembly is inserted. - said mechanical reinforcement means consist of a plurality of ribs connecting the receiving means to the peripheral wall of the body. - the ribs extend over at least part of the length of the sleeve. - the ribs extend radially from the sleeve. - each rib is attached to a corner of the body when the body section is polygonal. - the head insert has a top wall with a galvanized coating, visible from outside the device. - the head insert has an opening for the passage of the application assembly. - the device includes means for elastically fitting the application assembly into the receiving means ensuring axial locking between them. - said elastic interlocking means consist of an annular bead extending over the external perimeter of the application assembly and being able to fit under at least one protrusion protruding from an internal wall of the body, the protrusion acting as a hard point during the axial interlocking of the application assembly in the storage case. - the decorative coating is fixed to the peripheral wall of the body by exerting a pressure whose force is oriented perpendicularly to the central axis X. - the structure develops in the central part of the body, the upper and lower ends being free to accommodate the head and bottom inserts. - the body is molded in one piece. - The application assembly includes a gripping head that extends from the storage case through the head insert, and which has a galvanized coating. - the body is made of PP. - the head insert and the bottom insert are made of PP.

[0026] In the following description, elements having an identical structure or analogous functions will be designated by the same references.

[0027] By convention, the "axial" direction corresponds to the main extension direction of the device, illustrated by the X axis in [Fig.1], and the "radial" direction is directed orthogonally to the axial direction by radiating from the X axis.

[0028] In the detailed description of the figures that follows, the terms "upper" and "lower" or "top" and "bottom" shall be used without limitation with reference to the axial direction. The upper part of the device corresponds to the part of the application assembly that protrudes from the storage case.

[0029] Similarly, the terms "outside or external" and "inside or internal" are used with reference to the radial direction, an outside element being radially further away from the X axis than an inside element.

[0030] Figures 1 to 4 show an application device 1 for a solid cosmetic product. Preferably, the cosmetic product is a solid perfume intended to be applied by rubbing, as an alternative to a liquid perfume applied by spraying.

[0031] It mainly comprises an application assembly 3 and a tubular storage case 2. The application assembly 3 carries the cosmetic product, in this case a grape 12 of cosmetic product.

[0032] The application device 1 extends along the principal X-axis shown vertically in the figures. The application assembly 3 and the storage case 2 are centered on this X-axis.

[0033] As illustrated in [Fig. 1], the application assembly 3 is mounted inside the storage case 2. Part of the application assembly 3 protrudes from the storage case 2 and forms a gripping area for the user.

[0034] Thus, when the user wishes to use the device, he holds the storage case 2 in one hand, and with the other hand he grasps the gripping area of ​​the application assembly 3 and pulls it so as to separate it from the storage case 2 as shown in [Fig.2].

[0035] Fig. 3 shows the different parts composing the storage case 2 as well as the application assembly 3.

[0036] By means of a rotating mechanism 10, he can then bring out the grape 12 and apply it to his skin.

[0037] The application assembly 3 mainly comprises a gripping head 11 which cooperates with a mechanism 10 inside which the grape 12 is located. By rotating the gripping head relative to the mechanism 10, the grape 12 moves from an extended position (as illustrated in [Fig. 3]) to a retracted position (as illustrated in [Fig. 2]), and vice versa. The mechanism 10 transforms the rotational movement of the gripping head into a translational movement of the grape 12. This is a conventional mechanism 10, and is not the subject of the present invention.

[0038] Any mechanism 10 allowing a grape 12 of cosmetic product to be pushed out and pushed back in can be used within the framework of the present invention.

[0039] The present invention focuses on the design of the storage case 2, as well as on the overall aesthetics of the application device 1. Indeed, the entire device must be aesthetic, which implies that the case 2 must be aesthetic as well as the protruding part of the gripping head of the application assembly 3.

[0040] The aesthetics of the case 2 will be explained in the description below. As for the aesthetics of the gripping head, it is made of a plastic material, such as polypropylene, and has a galvanized outer coating providing an attractive aesthetic effect.

[0041] The storage case 2 consists mainly of a hollow body 4 extending along an extension direction of central axis X.

[0042] This body 4 gives the general external shape of the storage case 2.

[0043] This body 4 is formed by a peripheral wall 43 which delimits a cavity 21 interior.

[0044] The body 4 has a lower end 23 located near a bottom of the application device 1, and an upper end 22 located near the gripping head of the application assembly 3. These lower ends 23 and upper ends 22 are open, the cavity 21 being open on both sides.

[0045] The storage case 2 also includes a head insert 5 which is mounted on the body 4 at the upper end 22, and a bottom insert 6 which is mounted on the body 4 at the lower end 23. These inserts 5, 6 allow the open ends of the body 4 to be closed at least partially.

[0046] Each insert 5, 6 has a wall extending perpendicularly to the X-axis and visible from the outside. Each insert 5, 6 also has a peripheral skirt extending from the wall and having means for interlocking with the body 4.

[0047] Thus, the head insert 5 has an upper wall visible from the outside, and a peripheral skirt 54 hidden inside the body 4. As illustrated in detail A of [Fig. 4], the skirt 54 has a projection 52 adapted to fit inside a window 42 or a recess provided on the body 4 for this purpose, thus providing an elastic fit of the head insert 5 into the body 4. Preferably, the skirt 54 has two diametrically opposed projections 52 adapted to fit inside two equally opposed windows 42 on the body 4.

[0048] The bottom insert 6 has a lower wall 61 visible from the outside when viewing the device 1, and a peripheral skirt 63 hidden inside the body 4. As illustrated in detail C of [Fig. 4], the skirt 63 has a projection 62 adapted to fit inside a window 41 or a recess provided on the body 4 for this purpose, thus providing an elastic fit of the bottom insert 6 into the body 4. Preferably, the skirt 63 has two diametrically opposed projections 62 adapted to fit inside two equally opposed windows 42 on the body 4.

[0049] Preferably, the head insert 5 and the bottom insert 6 are both galvanized in order to give a certain aesthetic appeal to the storage case 2.

[0050] Preferably, at least the upper wall 51 of the head insert 5 and at least the lower wall 61 of the bottom insert 6 have a galvanized coating.

[0051] The body 4, the head insert 5 and the bottom insert 6 are all 3 made of a plastic material, therefore at low cost in terms of material.

[0052] The plastic material used is preferably recyclable. For example, it is polypropylene (PP), or polyethylene terephthalate (PET), or a composition involving one or both of PP and PET.

[0053] It is customary to place the case 2 vertically on a work surface. The base insert 6 is then in contact with the work surface.

[0054] To ensure that the case 2 remains upright, it is preferable to house a weight 13 at the level of the base insert 6, i.e., in the lower part of the case 2, in order to provide greater stability to the case 2 when it is upright. In this case, this weight 13 is positioned inside the peripheral skirt 62 of the base insert 6, and is therefore held radially by this skirt. The lower wall 61 of the bottom insert 6 axially supports this ballast 13.

[0055] The ballast 13 is made of a heavy material, such as sintered steel, or zamak.

[0056] In the embodiment shown in the figures, the body 4 has a section rectangular. Preferably, it has a square cross-section.

[0057] However, any other cross-sectional shape would also fall within the scope of the present invention. For example, the body 4 could have a round, oval, or carbide cross-section, etc.

[0058] To obtain a case 2 with a beautiful aesthetic, the body 4 is fitted with a decorative coating 7.

[0059] In the present case, this decorative covering 7 consists of a fabric that wraps around the body 4. It is a strip of fabric that is affixed all around the peripheral wall 43 of the body 4.

[0060] There is then a joining line of the fabric ends, which is preferably located on the back face of the case 2. This line should be as discreet as possible. It is illustrated in Figures 1 and 2 for example.

[0061] Any other material for the decorative coating 7 falls within the scope of the present invention. For example, it could be made of leather, or cardboard, or plastic, or stone veneer, etc.

[0062] Various techniques can be used to attach the decorative coating to the body 4 of the case 2. In particular, bonding or welding are preferred. In all cases, it is necessary to apply pressure to the coating on the body 4 until it adheres properly to the peripheral wall 43 and does not detach in the long term. However, applying such a force causes deformation of the peripheral wall 43 of the body 4. Since the force is directed perpendicular to the X-axis, a dent may form in the body 4 at the point where the force is applied. There may even be a risk of cracking of the body 4 if the force is too great.

[0063] To remedy this problem, the body 4 is provided with a structure 40 developing inside its cavity 21. The body 4 with its structure 40 are illustrated more particularly in figures 5 to 8.

[0064] This structure 40 allows for the mechanical reinforcement of the peripheral wall 43 of the body 4. This structure 40 is also made of plastic material, the same material as that of the peripheral wall 43.

[0065] Preferably the structure 40 is formed from the material with the peripheral wall 43. Thus the structure 40 and the peripheral wall 43 form only one piece, namely the body 4. For example the body 4 is made by molding, or by a known process of deposition by addition of material or additive deposition.

[0066] This structure 40 not only mechanically reinforces the body 4 but also provides a means of reception for the application assembly 3. Indeed, the application assembly 3 is partially disposed inside the body 4, as seen previously, and only a part of the gripping head protrudes from the body 4, and therefore a fortiori from the case 2. The structure 40, extending inside the body 4, is designed to optimally accommodate the application assembly 3, and to hold it in position when the device 1 is closed.

[0067] More specifically, this structure 40 consists of a central sleeve 44 extending along the direction of the body 4 corresponding to the X-axis, and into which the application assembly 3 is inserted. This sleeve 44 thus acts as a receiving means. This sleeve 44 is more clearly visible in [Fig. 6], for example.

[0068] In addition, this structure 40 has ribs 45 connecting this sleeve 44 to the peripheral wall 43 of the body 4. These ribs 45 are more clearly visible on [Fig.8] for example.

[0069] These ribs 45 extend radially from the sleeve 44. These ribs 45 therefore act as mechanical reinforcement. Thus, when a force is applied to the peripheral wall 43 during the fixing of the decorative coating 7, the ribs 45 are there to distribute, or even counteract, this force and ensure that the peripheral wall 43 does not deform.

[0070] More precisely, the central sleeve 44 extends in the central part of the body 4.

[0071] It extends over at least half the height of the body 4.

[0072] It does not extend in the lower part or in the upper part in order to leave room for the bottom insert 6 and the top insert 5, as well as the ballast 13.

[0073] The sleeve 44 is cylindrical in shape and hollow, to accommodate the application assembly 3.

[0074] This sleeve 44 has a neck 28 delimited from a main part 29 by a shoulder 47. When the application assembly 3 is mounted on the body 4, the gripping head 11 penetrates inside the body 4 until it comes to rest against this shoulder 47, as illustrated in the detail view B of [Fig.4].

[0075] Preferably, elastic interlocking means are provided between the neck of the sleeve 44 and the gripping head 11 to achieve axial locking.

[0076] These elastic interlocking means consist concretely of an annular bead 13 extending around the lower perimeter of the gripping head 11, capable of cooperating with at least one protrusion 46 projecting from the inner surface of the neck of the sleeve 44.

[0077] Preferably, the body 4 has at least two diametrically opposed protrusions 46. Even more preferably, the body 4 has four protrusions 46 arranged at 90° to each other, as can be seen in Figures 7.

[0078] This interaction between the annular bead 13 and the protrusions 46 allows for an elastic fit, the protrusions acting as passages for the hard points. With sufficient force, the user can remove the application assembly 3 from the body 4 by pulling on it and repositioning the hard points in the opposite direction.

[0079] Preferably, as illustrated in Figures 6, 7 and 8, the sleeve 44 has a base 48. This base 48 retains the ballast 13 in the lower part of the body 4 when the device 1 is handled and turned over, for example. Thus, the ballast 13 is held stationary between the lower wall 61 of the base insert 6 and the base 48 of the sleeve 44.

[0080] This sleeve 44 is attached to the peripheral wall 43 of the body 4 by means of the ribs 45 mentioned above. These ribs 45 thus connect the sleeve 44 to the peripheral wall 43.

[0081] Preferably, the structure 40 has at least two ribs 45 extending between the sleeve 44 and the peripheral wall 43 of the body 4. Preferably, they are diametrically opposed on the sleeve 44.

[0082] With a body 4 of polygonal section, here with four sides and four right angles, there are four ribs 45 connecting the sleeve 44 to each of the four angles.

[0083] With a body 4 of circular section, there could also be four ribs 45 connecting the sleeve 44 to the peripheral wall 43.

[0084] Preferably, each rib 45 is arranged at 90° with respect to the adjacent ribs 45.

[0085] The number of ribs 45 is not limited within the scope of the present invention.

[0086] Preferably, the ribs 45 are regularly distributed angularly around the sleeve 44, and have a radial length equivalent to the distance separating the sleeve 44 from the peripheral wall 43.

[0087] Preferably, the ribs 45 extend over the entire height of the sleeve 44.

[0088] Preferably, the ribs 45 extend over at least part of the height of the sleeve 44, in this case from the bottom 48 of sleeve 44 to the shoulder 47.

[0089] As illustrated in figures 7, this sleeve 44 is also attached to the peripheral wall 43 of the body 4 by means of a platform 27 oriented perpendicularly to the extension direction X,.

[0090] Preferably this platform 27 is located at the height of the shoulder 47 of the sleeve 44.

[0091] Preferably, the ribs 45 are also connected to the platform 27.

[0092] Preferably, as illustrated in Figures 6 and 7, the sleeve 44 has a plurality of bosses 49 inside in the vicinity of the bottom 48. These bosses 49 allow the application assembly 3 to be centered when it is introduced into the body 4.

[0093] In the present case, there are three bosses 49 distributed angularly and regularly on the lower periphery of the sleeve 44, on the inner side.

[0094] Each boss 49 has a ramp oriented towards the central axis X so as to progressively decrease the diameter of the sleeve 44. Thus, when the application assembly 3 is introduced into the case 2, the free end of the mechanism 10 comes into contact with these bosses 49 and slides on these ramps, so as to be progressively centered with respect to the sleeve 44, and then totally centered at the end of the stroke.

[0095] Optionally, the storage case 2 can be decorated with individual decorative elements 9 fitted into the body 4. For example, the peripheral wall 43 of the body 4 has a reception area 24 for these decorative elements 9. This reception area 24 is perforated to allow the decorative elements 9 to be fixed.

[0096] Preferably, means for reinforcing the receiving area 24 are provided. For example, these means for reinforcing consist of a reinforcing metal plate 8 affixed to the receiving area 24. More specifically, the receiving area 24 consists of a recess in the peripheral wall 43, allowing the metal plate 8 to be accommodated so that it is flush with the rest of the peripheral wall 43.

[0097] This metal plate 8 has a plurality of holes 81 to accommodate the decorative elements 9.

[0098] Similarly, the decorative coating 7 has a plurality of holes 72 to accommodate the decorative elements 9.

[0099] In the configuration shown in [Fig.3], the reception area 24 has two large openwork areas 26, while the metal plate 8 and the decorative coating 7 have small holes 81, 72 coinciding with the locations of the decorative elements 9.

[0100] The holes 81 of the metal plate 8 are arranged in the same locations as the holes 72 of the decorative coating 7 so that there is a correspondence between the holes 81, 72, these holes 81, 72 opening onto the openwork areas 26 of the reception area 24.

[0101] Each decorative element 9 has a pin 91 suitable for being inserted successively into the hole 72 of the decorative coating 7, then into the hole 81 of the metal plate 8, then into an openwork area 26 of the receiving face 24.

[0102] Alternatively, as illustrated in figures 5, 7 and 8, the reception area 24 also has small holes 25 aligned with those 81 of the metal plate 8 and those 72 of the decorative coating 7, instead of the openwork areas 26.

[0103] The ribs 45 make it possible to stiffen the peripheral wall 43 and thus make it possible to fix all these numerous decorative elements 9, without risking damage to the body 4 of the case 2.

[0104] The configurations shown in the cited figures are only possible examples, by no means limiting, of the invention which on the contrary encompasses variants of forms and designs within the reach of a person skilled in the art.
