Description

Title of the invention: Cosmetic product case comprising a lid and an intermediate plate lockable by rotation Technical field of the invention

[0001] The present invention relates to the field of cases for cosmetic products, in particular flat cases containing a cream, a balm, a solid powder makeup roller or a wax. Prior art

[0002] There are a significant number of cosmetic product boxes on the market today that can contain all types of products with different textures for multiple uses.

[0003] In the particular field of cosmetic products for the face (lips, cheeks, eyes), such as creams, balms or even more specifically compacted powders in the form of solid pebbles, the usual boxes are often very flat and typically comprise a base and a cover which can be moved between an open position giving access to the product and a closed position hiding said product so as to protect it and make it inaccessible.

[0004] Some of these boxes more specifically comprise a base on which a completely removable cover is mounted, generally screwed, or hinged around a hinge secured to the base, and between which an intermediate plate receiving the cosmetic product is placed.

[0005] A major problem lies in maintaining the lid on the base to prevent the product from spilling into a bag or being soiled. For this purpose, there are many boxes with a lid hinged around a hinge but which is not removable. In the field of boxes with a removable lid, a screwing system is commonly used which makes the closure rather secure so that the risk of accidental opening is low. But this type of closure is most often more complex to produce and leads to increasing the thickness of the boxes.

[0006] It follows from the above that current cases for cosmetic products with a completely removable or hinged lid are not optimized in terms of compactness, security of closure, ergonomics of use, ease of manufacture and recycling of its components.

[0007] Securing the cover in its closed position, preferably carried out in a reduced space requirement, therefore remains a complex problem that the invention aims to resolve. Presentation of the invention

[0008] The present invention aims to remedy these drawbacks with a completely innovative approach.

[0009] To this end, according to a first aspect, the present invention relates to a cosmetic product case comprising at least the following elements, extending successively along a longitudinal axis of rotation when they are assembled: - a lower base comprising at least one bottom, a first insert having a first circular wall erected axially opposite the bottom to form a first central housing adapted to receive a cosmetic product, - a cover separable from the base or hinged relative to the latter and comprising an upper plate from which a skirt is erected axially towards the bottom, - an intermediate plate inserted between the base and the cover and comprising at least one second insert having a second circular wall erected axially in the direction of the bottom to form a second central housing, said second circular wall being adapted to be mounted in a removable and coaxial manner around the first circular wall of the first insert of the base, and a covering mounted on the second insert and having for this purpose a peripheral skirt erected axially in the direction of the bottom and a second central opening arranged opposite the second central housing, said covering being adapted to be connected to the second insert of the intermediate plate using mechanical connection means, - the cover can take at least: * a first position, called closing, in which said cover closes the intermediate plate so that the interior of the case is concealed, making the product inaccessible, * a second position, called the use position, in which said cover is released from the intermediate plate so that the interior of the case is visible, making the product accessible, and * a third position, called locking, in which, from the first position, said cover and said intermediate plate are pivoted together axially relative to the base in a first direction of rotation by a number of degrees such that at least part of the connecting means move radially and come to bear against the inside of the skirt of the cover, preventing the latter from detaching from the intermediate plate and the base.

[0010] The invention is implemented according to the embodiments and variants set out below, which are to be considered individually or in any technically effective combination.

[0011] This solution allows the cover to be easily, quickly and intuitively locked onto the base using the intermediate plate. The cover can also take an open position so that the user can have access to makeup, or a simply closed but not locked position in cases where this latter function is not necessary (box placed on a bathroom shelf, a desk, a dressing table, etc.).

[0012] Preferably, the cover being of the detachable type - in the first position, the cover is hooked around the covering of the intermediate plate, - in the second position, the cover is detached and axially moved away from said covering of the intermediate plate and said base, and, - in the third position, the assembly composed of the cover and the intermediate plate is pivoted axially by at least 45° relative to the base (10), and preferably by approximately 90°

[0013] This solution, which more specifically concerns fully detachable covers and not covers articulated around a hinge, makes it possible to lock or detach said cover and the intermediate plate as a single unit with a natural and low-amplitude movement in order to be able to have access to the cosmetic product or to prevent unexpected access (involuntary opening of the cover).

[0014] Advantageously, the connecting means comprise on the one hand at least two diametrically opposite through slots formed in the thickness of the skirt of the covering of the intermediate plate and on the other hand at least two corresponding notches projecting from radially elastically deformable tabs belonging to the second circular wall of the second insert of the intermediate plate, said notches being permanently housed inside said through slots and moving away against the inside of the skirt of the cover in the third position, after execution of the rotation in the first direction of rotation to pass from the first position to the third position, under the effect of a radial force exerted to deform said tabs.

[0015] This solution highlights the simplicity of use of the locking means since they use few parts, few movements but very good security to prevent the cover from opening unexpectedly.

[0016] According to a preferred embodiment of the present invention, the skirt of the cover internally comprises four grooves distributed regularly over a common circumference and in which the notches are housed in the first position to connect the cover to the intermediate plate and come apart in the third position to lock said cover relative to the base.

[0017] This solution ensures quality anchoring to prevent the cover from unlocking by itself, using very few parts in a very small volume (low amplitude movements).

[0018] Preferably, the first circular wall of the base locally comprises at least two diametrically opposed support portions each provided with an inclined face exerting a radial force of separation of the legs as the latter pass during the axial rotation movement from the first position to the third position.

[0019] According to an additional characteristic, each tab internally comprises at least one attack ramp adapted to slide against the corresponding support portion of the first circular wall of the base in order to guide the assembly composed of the cover and the intermediate plate relative to the base during axial rotation from the first position to the third position.

[0020] This solution makes it possible to very easily transform an axial rotation movement into a radial translation movement in a very compact space.

[0021] More specifically, the second insert ) comprises, near each tab, a rear tooth cooperating with a front stop of the corresponding support portion to block the axial rotation of the assembly composed of the cover and the intermediate plate relative to the base once the third position is reached.

[0022] This solution allows the user to know, thanks to the rotation lock, that the cover is correctly and completely locked on the base without having to look at the gesture she is making to execute it. This contributes to offering intuitive and unconstrained use which could, for example, be done in the dark or without visibility (including, for example, for a person with a visual impairment and / or having motor difficulties in the hands).

[0023] According to a particular embodiment of the present invention,

[0024] Preferably, the first insert of the base also locally comprises at least two axially erected secondary walls trapping the second circular wall of the second insert of the intermediate plate against the first circular wall of the first insert in order to serve as a guide track during axial rotation from the first position to the third position, and vice versa.

[0025] This solution allows in particular to have very smooth (no jolts) and reliable kinematics when the parts rotate between them.

[0026] According to a complementary aspect, the first insert of the base comprises two secondary guide walls diametrically opposed and arranged angularly upstream of the support portions, in the first direction of rotation, said secondary guide walls exerting a centripetal pressure force on radial protuberances projecting internally from the second circular wall of the second insert of the intermediate plate.

[0027] More precisely, the first circular wall of the first insert of the base further comprises two local grooves cooperating with the radial protuberances of the second insert to axially hold the latter on said first insert once the third position reached

[0028] This solution allows the use of very few parts to perform different functions and ensure good locking of the cover and the intermediate plate on the base.

[0029] Advantageously, each secondary guide wall has two attack ramps with opposite slopes guiding the assembly composed of the cover and the intermediate plate relative to the base during axial rotation from the first position to the third position, and vice versa, in particular when each radially elastically deformable tab passes against a corresponding secondary guide wall.

[0030] Preferably, each radially elastically deformable tab is constituted by a central portion of material surrounded by two axial slots.

[0031] According to an advantageous characteristic, the first insert of the base further comprises radial ribs intended to return the radially elastically deformable tabs to their rest position during rotation from the third position to the first position of the assembly constituted by the cover and the intermediate plate.

[0032] This solution ensures that the cover will not remain locked in the first position.

[0033] In particular, the first insert of the base comprises two pairs of three diametrically opposed radial ribs angularly offset relative to the support portions and / or the secondary guide walls.

[0034] According to a particular characteristic of the present invention, the first peripheral wall of the first insert of the base comprises at least one bridge of radially elastically deformable material intended to exert a centripetal friction force on the cosmetic product in order to prevent its axial rotation.

[0035] This solution prevents the cosmetic product from rotating on itself during use, for example with a brush.

[0036] More precisely, the first peripheral wall of the first insert of the base comprises two bridges of material diametrically opposed and angularly offset relative to the support portions and / or to the secondary guide walls and / or to the radial ribs.

[0037] In this way, each function is independent of the others from a geometric point of view to avoid some of them interacting and disturbing each other.

[0038] Advantageously, the radial spacing of the notches when moving from the first position to the third position is between approximately a few tenths of a millimeter to a few millimeters, preferably between approximately 0.3 and 0.8 millimeters and advantageously approximately 0.5 millimeters.

[0039] This solution is particularly compact and can therefore be implemented in small boxes while remaining efficient.

[0040] According to a particularly interesting aspect of the present invention, the first insert is equipped with at least one pair of diametrically opposed bottom lugs, preferably four distributed regularly on the same circumference, to support the cosmetic product or a cup closing it.

[0041] In addition, the lugs provide a space, equivalent to their axial height, under the cosmetic product.

[0042] According to a preferred embodiment of the present invention, the base comprises a first set of magnets cooperating with a second set of magnets of the cover to hold the latter in the first position

[0043] This solution makes it easy to hold the cover on the base in a discreet and efficient manner.

[0044] Preferably, the general external contour of the base, the cover and the intermediate plate is substantially square, preferably with rounded edges of the “squircle” type.

[0045] Similarly, the general external contour of the first insert, of the covering of the first insert of the base, of the second insert, of the covering of the second insert of the intermediate plate, and of the cover is substantially square, preferably with rounded edges of the “squircle” type.

[0057] The present description is given without limitation, each characteristic of an embodiment being able to be combined with any other characteristic of any other embodiment.

[0058] It should be noted, from now on, that the figures are not necessarily to scale, without this hindering their understanding.

[0059] Figures 1 to 10 represent a case 1 in accordance with the present invention of a cosmetic product P, for example a solid roller of compacted makeup powder which can be contained in an intermediate rigid cup G acting as a receptacle.

[0060] This housing 1 mainly comprises three sub-assemblies extending successively along a longitudinal axis of rotation XX' when they are assembled, namely a base base 10 (also called lower base 10), a cover 20 movable relative to the base base 10 to close the housing 1 or give access to the interior of the base 10 of the latter, a mirror 25 fixed to the interior of said cover 25 and an intermediate plate 30 making it possible to receive the product roller P or the cup G.

[0061] At least some of these elements are made of molded or 3D printed plastic, preferably bio-sourced and recyclable such as polyethylene. Other elements can be made of aluminum or zamac, preferably also from the circular economy for better recyclability and preservation of nature.

[0062] According to the present invention, the cover 20 can take at least a first position ([Fig. 2]), called closing, in which said cover 20 closes the intermediate plate 30 so that the interior of the housing 1 is concealed, making the product P / the cup G inaccessible, a second position, called use, in which said cover 20 is released from the intermediate plate 30 so that the interior of the housing 1 is visible, making the product P / the cup G accessible, and a third position, called locking, in which, from the first position, the assembly composed of said cover 20 and said intermediate plate 30 is pivoted axially relative to the base 10 in a first direction of rotation (for example the clockwise direction, see [Fig.10]) by a number of degrees such that this assembly can no longer detach axially from the base 10, which makes it possible on the one hand to block access to the product P / bucket G but above all to secure the cover 20 in its closed position. on the base in order to avoid any unforeseen and untimely opening of the latter.

[0063] Thus, the base 10 typically comprises a flat bottom plate 10a measuring a few tenths of a millimeter to a few millimeters in thickness, for example between approximately 0.5 mm and 3 mm. This bottom plate 10a is in the present case attached (glued) to a first insert 12, but it could be integrated into the first insert 12 and directly form its bottom.

[0064] This first insert 12 of the base 10 has a bottom 11a, a peripheral belt 13 and is covered by a first covering 14 (aesthetic cover) having a first peripheral skirt 14a erected axially in the direction of the bottom 11a and a first central opening 14b arranged opposite the first central housing 12b of the first insert 12. The shape (section perpendicular to the axis XX') of the first skirt 14a of the first covering 14 and of the peripheral wall 13 of the first insert 12 are identical, the internal dimensions of the first peripheral skirt 14a being very slightly greater than the external dimensions of the peripheral wall 13 so that the first skirt 14a surrounds said peripheral wall 13 before being fixed, for example by gluing or clipping). In the present case, the peripheral wall 13 and the skirt 14a of the first covering 14 have, in cross section (i.e.perpendicular to the XX' axis), a square shape with rounded edges, also called a "squircle".

[0065] The first insert 12 firstly comprises a first internal circular wall 12a erected axially and directed away from the bottom 11a to form a first central housing 12b arranged opposite the first central opening 14b of the first covering 14 and adapted to receive the cosmetic product P or the cup G. It is on this circular wall 12a that the majority of the functionalities are implanted.

[0066] The intermediate plate 30, inserted between the base 10 and the cover 20 when the elements are assembled axially (at least in a first so-called closed position) comprises at least one second insert 32 having a second circular wall 32a erected axially in the direction of the bottom 11a to form a second central housing 32b coaxial with the first central housing 12b of the first insert 12 and with the first central opening 14b of the first covering 14. This second insert 32 also has a peripheral belt 33 having the same “squircle” shape as the peripheral belt 13 of the first insert 12 and as the first skirt 14a of the first covering 14.

[0067] This second circular wall 32a is adapted to be mounted in a removable and coaxial manner around the first circular wall 12a of the first insert 12 of the base 10 in the various positions mentioned above.

[0068] The intermediate plate 30 also includes a second covering 34 (aesthetic cover) mounted on the second insert 32 and having for this purpose a second peri-skirt spherical 34a axially erected in the direction of the bottom 11a and a second central opening 34b arranged opposite the second central housing 32b, said second covering 34 being adapted to be connected to the second insert 32 of the intermediate plate 30 using mechanical connection means 40 described later.

[0069] The first circular wall 12a of the first insert 12 also locally comprises at least two diametrically opposed support portions 15 each provided with a horizontally inclined face 15a, the slope and direction of these two inclined faces 15a being identical.

[0070] The second circular wall 32a of the second insert 32 comprises two radially elastically deformable tabs 43 which can thus move apart and return to their original position when moving from one position to another and vice versa (see below). These tabs 43 are geometrically identical and diametrically opposed. Each tab 43 comprises a central portion of material surrounded by two axial slots 45 allowing its radial elasticity. Each tab 43 also carries a notch 42 of oblong shape projecting radially outwards. Finally, each tab 43 is provided internally, in the immediate vicinity of the two axial slots 45, with two upstream and downstream attack ramps 44 with opposite horizontal slopes but of the same inclination, these attack ramps 44 (in particular the upstream ramps) being intended to cooperate by rotary sliding with the horizontal inclined sides 15a of the first circular wall 12a of the first insert 12.

[0071] The first insert 12 of the base 10 also locally comprises at least two secondary walls 16 erected axially trapping the second circular wall 32a of the second insert 32 of the intermediate plate 30 against the first circular wall 12a of the first insert 12 in order to serve as a “guide track” during axial rotation from the first position to the third position, and vice versa.

[0072] These two secondary guide walls 16 are identical and diametrically opposed and arranged angularly upstream of the support portions 15, in the first direction F of rotation (clockwise). These secondary guide walls 16 are designed to exert a centripetal pressure force on radial protrusions 32c projecting internally from the second circular wall 32a of the second insert 32 of the intermediate plate 30 and comprising two sliding planes 35 inclined vertically with identical slope. These two sliding planes 35 are adapted to cooperate with two inclined clearance ramps 19 arranged diametrically opposite on the first circular wall 12a of the first insert 12 of the base 10 and whose respective ascending slopes are oriented identically.

[0073] The first circular wall 12a of the first insert 12 of the base 10 further comprises two local grooves 12c cooperating with the radial protuberances 32c of the second insert 32 to axially hold the latter on said first insert 12, in particular once the third position is reached, when the secondary guide walls 16 press radially on said protuberances.

[0074] Each secondary guide wall 16 also has two upstream 16a and downstream 16b attack ramps (in the clockwise direction of rotation) with opposite slopes. These attack ramps serve to guide the assembly composed of the cover 20 and the intermediate plate 30 relative to the base 10 during axial rotation from the first position to the third position, and vice versa, in particular when each radially elastically deformable tab 43 passes against the corresponding secondary guide wall 16.

[0075] The first insert 12 of the base 10 further comprises two opposite pairs of radial ribs 18 intended to return the radially elastically deformable tabs 43 to their rest position during rotation from the third position to the first position (counterclockwise) of the assembly composed of the cover 20 and the intermediate plate 30. These pairs of three radial ribs 18 connect the first circular wall 12a and the peripheral belt 13 and are diametrically opposite and angularly offset relative to the support portions 15 and / or to the secondary guide walls 16.

[0076] The first peripheral wall 12a of the first insert 12 of the base 10 also comprises two bridges of radially elastically deformable material 17 intended to exert a centripetal friction force on the cosmetic product P or the cup G in order to prevent its axial rotation when it is used with a brush or the finger. These two bridges of material 17 are diametrically opposed and angularly offset relative to the support portions 15 and / or to the secondary guide walls 16 and / or to the radial ribs 18 to avoid any harmful interaction of the respective functions of each of these means.

[0077] The second insert 32 of the intermediate plate 30 further comprises, near each tab 43, beyond one of the axial slots 45, a rear tooth 47 cooperating with a front stop 15b of the corresponding support portion 15 of the first insert 12 to block the axial rotation of the assembly composed of the cover 20 and the intermediate plate 30 relative to the base 10 once the third locking position has been reached, which indicates to the user that the cover 20 is well held and cannot be turned further.

[0078] The cover 20 has on its side an upper wall 22, which can take a flat shape as shown or a more or less pronounced dome, from which a third skirt 24a is erected axially in the direction of the bottom 11a. The cover 20 is entirely separable from the base 10 but it could be articulated relative to the latter around a hinge. This cover 20 is held around the second skirt 34a of the second covering 34 of the intermediate plate using a lot 80 of four magnets 81 inserted in housings 82 provided for this purpose at the four corners of the cover 20 cooperating (from the point of view of their respective polarities) with a batch 70 of two magnets 71 inserted in housings 48 provided for this purpose in two opposite corners of the second 32 of the intermediate plate 30. The cover 20 can be removed (passing from the first closed position to the second position of use) by exerting a sufficient axial tensile force, or possibly even by tilting it.

[0079] The second insert 32 also comprises four housings 48 positioned in these corners which can receive two or four magnets 71 of a batch 70 of magnets which can cooperate with the magnets 71 and 81 of the batches 70 and 80 in order to improve the axial retention of the cover 20 on the base 10 in the first position.

[0080] As regards the mechanical connection means 40, the latter comprise on the one hand at least two diametrically opposed through slots 41 formed in the thickness of the second skirt 34a of the second covering 34 of the intermediate plate 30 and on the other hand at least two corresponding notches 42 projecting from the two radially elastically deformable tabs 43 belonging to the second circular wall 32a of the second insert 32 of the intermediate plate 30.

[0081] These prominent notches 42 are permanently housed inside the through slots 41 and move away against the inside 23 of the skirt 24a of the cover 20 after execution of the rotation in the first clockwise direction F to pass from the first position to the third position, under the effect of a radial force exerted by the inclined sides 15a on the attack ramps 44 to radially deform said tabs 43 in a centripetal manner. As can be seen in [Fig.5], the third skirt 24a of the cover 20 has internally for this purpose four grooves 24 distributed regularly on a common circumference and in which the notches 42 can be housed in the first position to connect the cover 20 to the intermediate plate 30 (by forming a mechanical clip, in particular in the hypothesis where the batches of magnets 60 and 80 are not present) and above all come to move apart radially in the third position in order to locally exert a thrust force against the wall 23 of said third skirt 24a when the tabs 43 move apart in order to lock the assembly composed of said cover 20 and said intermediate plate 30 relative to the base 10. The radial displacement of the notches 42 during the passage from the first position to the third position is between approximately a few tenths of a millimeter to a few millimeters, preferably between approximately 0.3 and 0.8 millimeters and advantageously approximately 0.5 millimeter. .

[0082] The rotation around the axis XX' to move from the first position to the third position is, in the end (when the tooth 47 rests against the stop 15b), approximately 90°, knowing that the deformation of the tabs 43 / the spacing of the notches 42 begins at approximately 45° of rotation.

[0083] Once the notches 42 are in the grooves 24, the assembly composed of the cover 20 and the intermediate plate 30 is in the locked position and can therefore no longer be detached from the base 10, except by performing the reverse rotation movement to return the tabs 43 to their initial position and release the notches 41 from the grooves 24 of the cover 20.

[0084] The first insert 12 is equipped with at least one pair of diametrically opposed bottom lugs 12d, preferably four distributed regularly on the same circumference, to support the cosmetic product P or a cup G closing it. These lugs 12d thus provide a space under the cosmetic product equivalent to their axial height. In the event that the cup G (or the cosmetic product P itself) is provided with four slots opposite said lugs 12d, the cup G (or the cosmetic product P) rests directly on the bottom of the first insert 12, which makes it possible to have a larger quantity of product because there is no longer the empty zone underneath. The cooperation of these slots with the lugs 12d can also serve as an indexing guide to position the cup G / product P in the central opening 12b of the first insert 12 and prevent axial rotation of said cup / product.

[0085] Finally, the bottom of the first insert 12 comprises, beyond the first circular wall 12a, two axially elastically deformable tabs 50 arranged diametrically opposite each other and each provided with an axial protuberance 52 and an upstream void 51. This space 51 and this protuberance 52 cooperate with a tooth 39 projecting axially under the second circular wall 32a of the second insert 32 and allows a slight blocking preventing too easy axial rotation of the assembly composed of the cover 20 in the counterclockwise direction from the first position.

[0086] It will be noted that it is mainly the cooperation of the substantially square shapes ("squircle") of the different elements, in particular the third skirt 24a of the cover and the second skirt 34 of the intermediate plate 30, which allows the axial rotation of this assembly relative to the base 10 in a direction F (clockwise) or in the opposite direction (anticlockwise) to pass respectively from the first position to the third position, and vice versa. These similar shapes fit into each other and create this drive allowing the rotation of the assembly composed of the cover and the intermediate plate 30 while contributing to the overall aesthetics of the housing 1.

[0087] In the event that the housing 1, in particular the assembly composed of the cover 20 and the intermediate plate 30, would have a round section and no longer a polygonal one, it would be necessary to provide small lugs of material on the outside of the second skirt 34a of the second covering 34 and corresponding slots inside the third skirt 24a of the cover 20 so that these two parts mesh like a drive shaft. Four lugs distributed at 90° to each other and thirty-six slots would allow for example an engagement every 10 degrees, which seems sufficient to serve as a de misleading so that the user avoids fumbling to reposition the cover 20 on the second covering 34 of the intermediate plate 30 when moving from the second position of use (cover completely removed) to the first closed position, and which would make it possible to provide sufficient rotational driving force to move from the first closed position to the third locking position, and vice versa.

[0088] It should be clearly understood that the detailed description of the subject of the Invention, given solely by way of illustration, does not constitute in any way a limitation, the technical equivalents also being included in the scope of the present invention.

[0089] Thus, the number, position, slopes (their inclination and length in particular) of the various functional elements such as the tabs 43, the notches 42, the through slots 41, the grooves 24, the inclined sides 15a, the attack ramps 44, the rear teeth 47, the front support stops 15a, the axial teeth 39, the axial protuberances 52, the sliding planes 35, the inclined clearance ramps 19, the attack ramps 16a and 16b, the radial ribs 18, the material bridges 17 or even the lugs 12d may be different.
