Description

Title of the invention: CUPULE FOR A COSMETIC PRODUCT GRAPE Technical field of the invention

[0001] The invention relates to a cup for a device for applying a cosmetic product grape, having a central axis, the cup having a receiving housing for the cosmetic product grape delimited radially by a lateral wall having an upper end edge which borders a passage for the cosmetic product grape, an inner face of the lateral wall having at least one gripping relief for the cosmetic product grape and a protrusion. Technical background

[0002] Prior art is known for application devices used for packaging a cosmetic product, such as a cosmetic product stick, particularly but not exclusively for a lipstick stick. Such a cosmetic product stick will be referred to hereafter and in the claims as a "stick".

[0003] The grape is held by its base in a cup. In most application devices, the cup slides axially between at least one retracted position and a cosmetic product application position in which at least part of the cosmetic product grape extends axially out of the device.

[0004] Several methods are known for forming the grape of cosmetic product.

[0005] One method consists of pre-forming the cosmetic product grape, then inserting, or "piercing," the grape into the cup after assembling the device. This method is particularly effective when the cosmetic product constituting the grape has sufficient mechanical strength.

[0006] Another method consists of molding the cosmetic product in liquid form by injecting it directly into the cup of the previously assembled device. This method is particularly suitable when the cosmetic product has a so-called "soft" to "very soft" formulation. The cosmetic product's liquid form, in fact, has insufficient mechanical strength to allow for injection.

[0007] Regardless of the method used, the retention of the grape in the cupule is ensured by gripping ridges present inside the cupule.

[0008] The cup is a part made of plastic material, particularly thermoplastic material, which is obtained by molding. The cup is obtained, for example, by injection molding in a mold made of several parts. For reasons of industrial efficiency, the mold is always durable and is reused very frequently. many times to quickly obtain thousands of cups. The mold, for example, is made of a metallic material.

[0009] To allow for the demolding of the cups, the mold is made of at least two parts that can be axially separated from each other along a demolding axis that coincides with the axis of the grape after it has been placed in the cup. Due to this manufacturing technique, the shape of the gripping reliefs is limited by the demolding constraints of the thermoplastic injection molding.

[0010] Thus, the gripping reliefs generally do not have faces turned axially towards the bottom of the cup because it would not be possible to separate the two parts of the mold axially to allow demolding.

[0011] For this reason, the gripping reliefs are generally in the form of radial ribs, solid and straight, extending axially inside the cupule.

[0012] However, such solid gripping ridges extending axially from the bottom of the cup do not always allow the grape to be retained effectively in the cup along the axial direction. This problem is particularly exacerbated when the grape consists of a cosmetic product with a soft to very soft formulation.

[0013] It has already been proposed to create gripping reliefs having a lower face turned towards the bottom of the cup in order to retain the grape more effectively in the cup along the axial direction. To create such gripping reliefs, it has already been proposed to provide mold passage windows in the side wall of the cup directly below said lower face or in the bottom of the cup opposite said lower face.

[0014] Such a mold is very complex and expensive to produce.

[0015] Furthermore, such a process only allows the creation of a single hook relief along the demolding axis.

[0016] There is therefore a need to easily and inexpensively produce gripping reliefs that effectively retain the grapes along the axial direction. Summary of the invention

[0059] The [Fig.12] is an axial sectional view along the section plane 12-12 of the [Fig.11]. Detailed description of the invention

[0060] By convention, the "axial" direction corresponds in the figures to that of the main axis A of the device (also called mechanism) intended to be mounted on an actuation base of a cosmetic product application receptacle, such as a cosmetic product bullet, in particular a lipstick bullet, and the "radial" direction is directed orthogonally to the axial direction by radiating from the main axis.

[0061] In the detailed description of the figures that follows, the terms "upper" and "lower" or "top" and "bottom" will be used without limitation in reference to the axial direction, the upper part of the device corresponding to that through which the cosmetic product grape exits the device for application.

[0062] 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 axis A than an inside element.

[0063] Hereafter a “circumferential direction” means along a direction rotating around the main axis “A” of the cupule.

[0064] Hereafter, the expression "at the right of" means above and at a distance along an axial direction parallel to the axis "A".

[0065] Subsequently, when two elements are made "in one piece", this means that the two elements are made of the same material and are part of the same piece produced in a single manufacturing operation, such as a molding operation or a three-dimensional printing manufacturing operation.

[0066] Figures 1 to 10 show several examples of the embodiment of a cup 10 for a device 12 for applying a cosmetic product applicator 14. The applicator 14 is shown with dashed lines.

[0067] Preferably, the cosmetic product grape 14 is a lipstick grape intended to be applied by rubbing, alternatively a lip balm.

[0068] The cup 10 is generally designed to be slidably mounted relative to a base of the application device 12. A non-limiting example of such an application device 12 will be described in more detail later with reference to Figures 11 and 12.

[0069] The cup 10 can also be fitted to an application device in which it is fixed relative to the base of the application device.

[0070] The cup 10 has a lateral wall 16 which extends along an axis "A".

[0071] The lateral wall 16 here has the shape of a right cylinder whose generatrix can to present a circular shape, or any other shape, for example prismatic with rounded corners. The lateral wall 16 therefore forms a cylindrical wall here.

[0072] An internal face 16A of the lateral wall 16 radially delimits a housing 18 for receiving a lower part of the grape 12.

[0073] The housing 18 is open upwards by a passage 20 allowing an upper part of the grape 14 to extend axially outwards from the housing 18. The lateral wall 16 has an upper end edge 22 which borders the opening 20.

[0074] The housing 18 is axially delimited downwards by a bottom 24. The bottom 24 can be fully open, as shown in Figures 1 to 4, or it can be only partially open, as shown in Figures 5 to 10. Such an open bottom 24 is for example intended to allow the injection of the cosmetic product during its molding directly into cup 10.

[0075] The internal face 16A of the lateral wall 16 has at least one 26 snagging relief for the cosmetic product grape 14 which extends radially in projection towards the interior of the housing 18.

[0076] The attachment relief 26 has at least one lower face 28 turned towards the bottom 24 of the cupule 10.

[0077] The terms "facing towards the bottom 24" mean that such a lower face 28 is visible on a view from below of the attachment relief 26 by axial projection along the direction of axis A. Thus, a lower face 28 does not necessarily extend in a strictly radial plane but it can also be inclined.

[0078] The lower face 28 is thus arranged axially at a distance from the bottom 24. Such a lower face 28 makes it possible to retain the grape 14 very effectively inside the housing 18, in particular against an axial pull-out force.

[0079] The portion 30 of the internal face 16A of the lateral wall 16 located axially directly below said lower face 28 is solid.

[0080] Furthermore, the lateral wall 16 has at least one protrusion 32. In the embodiments shown in the figures, the protrusion 32 projects radially inwards from the lateral wall 16. The protrusion 32 is preferably formed as a single piece with the wall 16.

[0081] The protuberance 32 is located axially opposite at least a portion of said lower face 28 of one of said attachment reliefs 26.

[0082] As shown in all embodiments, the lateral wall 16 delimiting the housing 18 is completely solid. This makes it possible to obtain a strong and solid cup 10.

[0083] The side wall 16 and the attachment ridges 26 are made in one piece. They are, for example, made of thermoplastic material such as resin or of metal.

[0084] In the embodiments shown in the figures, each attachment relief 26 is obtained directly in its final position during the manufacture of the side wall 16. This means, in particular, that the attachment relief 26 is not obtained by deforming the side wall 16 after its manufacture.

[0085] The contour of the first attachment relief 26 is entirely in contact with the lateral wall 16 around its entire perimeter.

[0086] In the example shown in figures 1 and 2, the internal face 16A of the lateral wall 16 has a plurality of gripping reliefs 26, at least one lower face 28 of which is turned towards the bottom 24 of the cupule 10.

[0087] The portion 30 of the lateral wall 16 located axially directly below said lower face 28 of each attachment relief 26 is solid.

[0088] Furthermore, the attachment relief 26 and the protrusion 32 are separated by a portion of the lateral wall 16. This portion of the lateral wall 16 is here devoid of any recessed or projecting elements. This portion of the lateral wall 16 is here solid.

[0089] This means that there is at least one axial cutting plane passing through axis A, along which the inner face 16A of the lateral wall 16 has a first radial projection forming the attachment relief 26 and a second radial projection forming the protrusion 32. Along said cutting plane, the attachment relief 26 is arranged at a distance above the protrusion 32. The attachment relief 26 is thus separated from the protrusion 32 by the solid portion 30 of the lateral wall 16. The inner face 16A of the lateral wall 16 extends parallel to axis A here.

[0090] The attachment features 26 are here formed by distinct projections arranged regularly around the central axis "A". The term "distinct" means that each attachment feature 26 is completely surrounded by a portion of the internal face 16A of the lateral wall 16 which is devoid of projections.

[0091] The attachment ridges 26, formed by distinct projections, are arranged in a pattern with at least two attachment ridges 26 spaced along an axial extension direction. Thus, several attachment ridges 26 extend along an axial alignment. In this way, for all the attachment ridges 26 on the same axial alignment, except for the one arranged at the lower end, the attachment ridge 26 located directly below it forms said protuberance 32 projecting radially inwards.

[0092] In this embodiment, the bottom 24 of housing 18 is completely open.

[0093] In the example shown in Figures 1 and 2, the attachment reliefs 26 present 26 attachment reliefs aligned along a helical extension direction around the axis "A".

[0094] In the example shown in figures 1 and 2, the 26 hanging reliefs are more particularly arranged in a staggered pattern.

[0095] Each gripping relief 26 is presented here in the form of a pin having a circular contour and delimited by a cylindrical face with radial axis relative to the main axis "A" of the cupule 10. The lower half of the cylindrical face forms the lower face 28 of the gripping relief 26.

[0096] Figures 3 and 4 show a second embodiment of the cupule 10 in which the cupule 10 is identical to that of the first embodiment except that the attachment reliefs 26 have a different contour and arrangement.

[0097] Indeed, in this second embodiment, the 26 attachment reliefs are distributed not in a staggered pattern but according to a square grid in which each relief 26 of attachment located at a given level is arranged directly above a relief 26 of attachment of the level located directly below.

[0098] As in the first embodiment, for all the attachment reliefs 26 of the same axial alignment, except the one arranged at the lower end, the attachment relief 26 located directly below forms said protuberance 32 projecting radially inwards.

[0099] Furthermore, each attachment relief 26 here has an oblong contour whose major axis extends in an oblique direction. Thus, several attachment reliefs 26 are aligned in a helical direction along their major axis.

[0100] Each attachment relief 26 thus has a lower face 28 of which at least a portion extends obliquely along its major axis.

[0101] Figures 5 and 6 show a third embodiment of the invention.

[0102] In this embodiment, the cup 10 has a bottom wall 34 which extends radially inwards from the internal face 16A of the lateral wall 16.

[0103] The bottom wall 34 is made in one piece with the side wall 16.

[0104] The bottom wall 34 of the housing 18 has an annular peripheral zone which extends radially from the inner face 16A of the lateral wall 16 inwards over a distance greater than the maximum radial dimension of the attachment reliefs 26. This peripheral area is entirely solid.

[0105] The bottom wall 34 of the cup 10 has a central area located inside the peripheral area which includes at least one orifice 36 for injecting the cosmetic product intended to form the grape 14.

[0106] In this embodiment, the attachment ridges 26 have the form of ribs extending upwards from the bottom wall 34 along an axis of extension inclined relative to the axial direction "A". The attachment ridge 26 thus has a helical shape. The attachment ridge 26 extends upwards here to near the upper edge 22 of the side wall 16.

[0107] Thus, the rib-shaped attachment relief 26 is delimited in a circumferential direction by an inclined lower face 28 which is turned towards the bottom 24, and by an opposite face 36 turned towards the passage 20.

[0108] In this embodiment, the bottom wall 34 forms said protuberance 32 projecting radially inwards which is arranged opposite the lower face 28 of the attachment relief 26.

[0109] The cupule 10 here has several identical attachment reliefs 26, for example eight, which are distributed regularly around the axis "A".

[0110] According to a fourth embodiment, which is shown in Figures 7 and 8, the cupule 10 is identical to that of the third embodiment; however, each rib-shaped attachment relief 26 has a notch 38 which divides the rib in at least two distinct attachment reliefs 26. The notch 38 extends in fact to the internal face 16A of the lateral wall 16.

[0111] Each rib further has a second notch at its lower end. Thus, each rib is divided into two distinct gripping reliefs 26 and the downward-facing gripping relief 26 extends a distance above the bottom wall 34.

[0112] Thus, each attachment relief 26 has, in addition to the lower face 28A which extends in an inclined manner with respect to the axis "A", a second lower face 28B which extends substantially in a radial plane.

[0113] According to a fifth embodiment of the invention shown in figures 9 and 10, the cup 10 has a gripping relief 26 formed of crossed salient lines 40, such as an embossing.

[0114] The projecting lines 40 extend here in a helical direction in one direction and then the other so that the intersecting lines delimit rectangular or square alveoli 42, the bottom of which is formed by the internal face 16A of the lateral wall 16. Thus, each alveoli 42 is delimited upwards by lower faces 28 facing towards the bottom 24 of the cupule 10 and downwards by faces which form said protuberance 32.

[0115] In each of these embodiments, the grape is advantageously injected and molded directly into the cup 10, while each gripping ridge 26 is already radially projecting inwards. Thus, the cosmetic product constituting the grape 14 envelops the gripping ridges 26 during its pouring. The cosmetic product constituting the grape 14 is advantageously poured under the lower faces 28, thereby ensuring good support and retention of the grape 14 in the cavity 18 of the cup 10.

[0116] Alternatively, the grape 14 is inserted into the cup after its molding. When the grape 14 is made of a particularly soft cosmetic product, part of the cosmetic product can thus flow under the lower faces 28 of the gripping ridges 26 after its inserting, the gripping ridges 26 being already raised before the inserting.

[0117] Regardless of the embodiment, the cup 10 is advantageously made in one piece by application of a three-dimensional printing manufacturing process, such as laser sintering or resin photopolymerization processes.

[0118] Such a process is indeed suitable for the mass production of such cupules 10.

[0119] Such a process generally involves:

[0120] - a first step in developing a digital model of the cupule

[0121] - a second conditioning step of a powdered or liquid material;

[0122] - a third solidification step of the material by defined slices from the digital model.

[0123] Said powdery or liquid material is capable of being solidified by photopolymerization, in particular by means of a light source including a laser.

[0124] Alternatively, the powdered or liquid material can be solidified by sintering, in particular by means of a heat source including a laser.

[0125] The liquid or powdery material is generally placed in a receptacle equipped with a support for the solidified material and the support is moved in steps equal to the thicknesses of the slices defined from the numerical model.

[0126] The liquid or powdered material comprises at least one component, mixed where appropriate with an additive, this component being chosen from a photopolymer resin, a sintering resin, a metal and / or a metal alloy.

[0127] Such a process is particularly suitable for producing cups 10 because the number, geometry, and arrangement of the gripping ridges 26 are all parameters that must be adapted to the composition and texture of the cosmetic product bullet, as well as to its method of insertion into the cup, whether by piercing or molding. The digital model of the cup is thus created based on these parameters.

[0128] This makes it easy to obtain a wide variety of cups without having to make a mold for each one.

[0129] Among the three-dimensional printing processes that could be used to produce the cup 10, selective laser sintering, or SLS, can be mentioned. This technology uses powdered materials, generally plastic or metal. The cup is obtained layer by layer from the powder, which is sintered or fused using the energy of a high-power laser that heats the powder beyond the glass transition point, causing the particles to agglomerate.

[0130] Another example of a three-dimensional printing process that can be used to produce the cup 10 is stereolithography, or SLA (StereoLithography Apparatus), which uses a liquid resin that hardens upon exposure to ultraviolet (UV) rays. A UV laser beam scans the surface of the resin and thus hardens the material on a section of the product to create, layer by layer, the cup 10 from bottom to top.

[0131] Another example of a three-dimensional printing process that could be used to produce the cupule 10 is DLS technology, an acronym for "Digital Light Synthesis". This technology is similar to stereolithography as described above; however, the resin hardening is achieved by projecting radiation directly onto the entire surface. the liquid resin surface, which allows a 10 cup to be made even faster.

[0132] These three three-dimensional printing technologies are given by way of non-limiting example, other already known three-dimensional printing technologies can of course be used.

[0133] According to another aspect of the invention, the cup 10, whatever its embodiment, includes at least one translational drive element in the application device 12.

[0134] In the embodiments shown in Figures 1 to 10, the drive members are formed by lugs 44 extending radially outwards from an external face 16B of the lateral wall 16. The lugs 44 are thus formed as a single piece with the lateral wall 16 defining the housing 18.

[0135] In an unrepresented variant of the invention, at least one drive member is carried by a separate part which is attached to the lateral wall 16 delimiting the housing 18. This variant is particularly interesting in that it allows the same cup 10 to be used with several types of application devices by simply changing the separate part carrying the drive members.

[0136] In an unrepresented variant of the invention, the drive element is formed by a screw.

[0137] A non-limiting example of an application device 12 is now described in which the cup 10 made according to any one of the embodiments is capable of being mounted.

[0138] Figures 11 and 12 illustrate the device 12 which is intended to be mounted on an actuation base of a cosmetic product application receptacle.

[0139] The device 12 is designed to expel the cosmetic product by at least one rotational movement.

[0140] The device 12 has a main axis which is coaxial with the axis "A" of the cup 10.

[0141] The device 12 comprises at least one first element, conventionally and hereafter called guide 46. The guide 46 mainly comprises a tubular body 48 which extends axially from a base 50 forming the lower end of the guide 46 to an upper outlet opening 52 intended to be traversed by the grape 14 of cosmetic product.

[0142] Preferably, the guide 46 has at least one slot passing radially through the wall of the body 48. Each slot forms a slide. The guide 46 here has a first slot 54 and a second slot 56 passing radially through the wall of the body 48. The slots 54, 56 are arranged diametrically opposite each other.

[0143] The slots 54, 56 extend axially within the body 48 of the guide 46; the first slot 54 is axially closed at its upper end, while the second slot 56 is open. The slots 54, 56 are closed at their lower end located on the side of the base 50.

[0144] The slots 54, 56 each have straight and parallel edges. The first slot 54 has at one of its axial ends an upper notch 58a and at the other of its ends an lower notch 60a, said notches 58a, 60b extending circumferentially.

[0145] In both embodiments, the second slot 56 also has upper and lower notches 58b, 60b.

[0146] In conventional systems, the notches 58a, 58b, 60a, 60b are intended to form means for blocking the end of the stroke of the cup 10.

[0147] The device 12 includes the cup 10 made according to the teachings of the invention which receives the grape 14 of cosmetic product.

[0148] The cup 10 is intended to be mounted sliding axially in the guide 46, between an extreme retracted position and an extreme deployed position.

[0149] The extreme retracted position corresponds to a position in which the grape 14 is inside the device 12 for its protection and storage and the cup 10 is in the lower end-of-travel position.

[0150] The extreme deployed position corresponds to a position in which the grape 14 is deployed axially upwards so that its upper part extends out of the device 12 through the opening 52 and the cup 10 is in the upper end-of-travel position.

[0151] The cup 10 can also be in intermediate positions between its two extreme retracted and deployed positions, called intermediate application positions.

[0152] Each lug 44 of the cup 10 is engaged in one of the slots 54, 56 of the guide 46 and through them to extend radially outwards beyond the external cylindrical surface of the body 48 of the guide 46.

[0153] The device 12 includes a second element, conventionally and hereafter called the sheath 62. As represented here, the sheath 62 has a cylindrical shape with principal axis A.

[0154] The sheath 62 can receive an outer sleeve (not shown) into which the sheath 62 is inserted and immobilized against rotation due to force assembly or, for example, the use of glue to fix the sheath 62 and the sleeve together.

[0155] Preferably, the sheath 62 has internally at least one groove receiving the free end of a lug 44 associated with the cup 10. The sheath 62 here has two diametrically opposed grooves 64, 66, with which the free ends of the The lugs 44 of the cup 10 cooperate during operation. The sheath 62 has an inner wall provided with the said grooves 64, 66. The grooves 64, 66, here have a helical shape.

[0156] The sheath 62 respectively comprises an upper edge 68 located at its upper axial end and a lower edge 70 located at its lower axial end.

[0157] The sheath 62 is intended to be mounted by snapping it onto the guide 46 to obtain, after assembly, the device 12.

[0158] The guide 46 is mounted for rotation in the sleeve 62 about the main axis "A". The guide 46 is thus received concentrically inside the sleeve 62. For this purpose, the body 48 of the guide 46 has an external diameter substantially equal to the internal diameter of the sleeve 62.

[0159] In such a device 12, the rotation of the guide 46 via its base 50 relative to the sheath 62 causes an axial movement of the cup 10, more precisely an upward or downward movement of the cup 10 according to the direction of rotation by cooperation between the lugs 44, the slots 54, 56 and the grooves 64, 66.

[0160] The cosmetic product grape 14 moves axially with the cup 10 between the extreme deployed position and the extreme retracted position.

[0161] In both embodiments shown, the guide 46, the cup 10 and the sheath 62 are advantageously made of plastic and / or metal.

[0162] Preferably, the guide 46, the cup 10 and the sheath 62 are made of the same plastic material.

[0163] The cupule 10 made according to the teachings of the invention can of course be applied to other types of application device.
