Description

Technical Field

[0001] The present invention relates to a coating device for coating cosmetics, in particular a cosmetic stick, the coating device comprising:

[0002] an application assembly extending along the main axis and comprising at least one application element for applying the cosmetic product and at least one base for manipulating the application element, the application element having a free application end, the base carrying the application element by an end opposite to the free end;

[0003] a tubular storage housing extending along the main axis and spaced apart from the applicator assembly, the housing having an upper end edge defining an opening and a lower end closed by a bottom, the housing being intended to coaxially receive the applicator assembly via its free applicator end;

[0004] - a sliding portion, the sliding portion being axially slidably mounted in the housing and the coating assembly being intended to be held in a storage position in the sliding portion, the sliding portion being slidable between an extreme retraction position and an extreme use position, in which the base is axially pushed into the housing to prevent the base from being gripped, and in which the base protrudes axially relative to the upper end edge to enable the base to be gripped to remove the coating assembly from the housing;

[0005] - A control mechanism for controlling the sliding of the sliding part between the two positions of the sliding part. Background Art

[0006] Typically, an application device for applying cosmetics, in particular cosmetic sticks, comprises an application portion attached to a base so that it can be manipulated by a user. In the case of lipstick or equivalent lip cosmetics, the application portion is directly formed by the cosmetic stick.

[0007] The application assembly formed by the base and the application part effectively protects the application part (in this case, the cosmetic stick) by a cover or a shell that cooperates with the base. Usually, the application part is inserted into the cover or the shell so that only the base is visible. Therefore, the application part is protected by the shell or the cover. This enables the device to be stored in a bag without the risk of damaging the application part.

[0008] Typically, the base portion remains accessible because the housing only covers the applicator portion.

[0009] Although this configuration is generally satisfactory, it has been found that in some circumstances the applicator assembly may be accidentally removed from its storage housing, for example when searching for a bag containing the device.

[0010] Furthermore, in the case of an applicator for applying cosmetics in the form of a stick, the applicator assembly typically includes a mechanism for retracting the stick into a sheath. The mechanism typically operates by rotating the base relative to the sheath. When the mechanism is activated, the stick extends from its sheath during use. When the applicator assembly is stored in the housing, the cosmetic stick is retracted into its sheath so that the cosmetic stick is not crushed by the bottom of the housing.

[0011] However, when the base is inadvertently rotated while the applicator assembly is stored in its housing, the cosmetic stick is damaged due to contact with the bottom of the housing.

[0012] In order to solve these problems, housings have been proposed in which the entire applicator assembly including the base can be inserted. In order to access the applicator assembly, it is necessary to equip the housing with a mechanism enabling the applicator assembly to slide between a storage position, in which the base is pushed into the housing and is therefore inaccessible, and a use position, in which the base protrudes sufficiently from the housing to be gripped by the user.

[0013] The existing housing includes a sliding mechanism equipped with an elastic member, which enables energy to be stored when the applicator assembly is pushed into the storage position of the applicator assembly. The applicator assembly is held in its storage position by a cam locking member similar to the cam locking member of a retractable ballpoint pen against the elastic return force of the elastic member. In order to release the applicator assembly, the user must push the base back slightly into the housing. The applicator assembly thus released is then pushed by the elastic member to the use position of the applicator assembly.

[0014] However, the structure of such a housing is complicated and requires a large number of components. Therefore, the housing obtained thereby is expensive to manufacture.

[0015] Furthermore, many of these components are made from materials that cannot be recycled in the same process. The individual components need to be separated to effectively recycle the device. This is particularly the case with springs that are made from metal. Summary of the invention

[0057] By convention, the "axial" direction in the drawings corresponds to the direction of the main axis "A" of the application assembly of the cosmetic application device or the main axis "B" of the shell, and the "radial" direction is oriented orthogonal to the axial direction and extends from each main axis "A", "B", the cosmetic being, for example, a cosmetic stick, in particular a lipstick stick.

[0058] In the following detailed description of the drawings, the terms “upper” and “lower” or “top” and “bottom” will not be limitedly used to indicate the positions of elements in the drawings being described.

[0059] Similarly, the terms "outer or outer" and "inner or inner" are used to refer to radial directions, with outer elements being radially farther from the axis "A" or "B" than inner elements.

[0060] Figures 1 to 3 An application device 10 for applying cosmetics is shown. Preferably, the cosmetics (e.g. Figure 6 and Figure 7 ) is a lipstick, or lip balm, intended to be applied by rubbing on.

[0061] The coating device mainly includes a coating assembly 14 and a tubular storage housing 16 .

[0062] The application assembly 14 extends along a main axis "A" shown vertically in the figures. The application assembly comprises at least one cosmetic application element 18 having a free application end 18A and an opposite base end 18B. As a non-limiting example, the application element 18 is here formed by a cosmetic stick.

[0063] like Figures 4 to 7 , the application assembly 14 comprises at least one manipulation base 20 for manipulating the application element, the manipulation base carrying the application element 18 by its base end 18B. The base 20 is intended to be held by a user to be able to manipulate the application assembly 14 and to apply cosmetics by applying the free application end 18A of the application element 18.

[0064] The base 20 has a tubular axial wall 21 which is closed towards the bottom by a radial bottom 23 .

[0065] As a non-limiting example, the applicator assembly 14 comprises a control mechanism 22 for controlling the sliding of the applicator element 18 formed by a cosmetic stick. The base 20 carries the applicator element 18 via the mechanism 22 .

[0066] The mechanism 22 is designed to extend the application element 18 by at least one rotational movement.

[0067] The mechanism 22 extends along an axis "A".

[0068] Now describe as Figure 4 and Figure 5 An example of an embodiment of such a mechanism 22 is shown.

[0069] The mechanism 22 comprises at least one guide 24. The guide 24 comprises essentially a tubular body 26 extending axially from a hub 28, the hub forming an end at the bottom of the guide 24, to an outlet opening 30 (see Figures 4 to 7 ), outlet opening (such as in Figures 4 to 7 ) is intended to be passed through by the application element 18 .

[0070] The hub 28 is attached inside the base 20, for example by force interlocking into a housing in the base 20, which is delimited by the axial wall 21 and the bottom 23. To this end, the axial base 20 is open at its axial end opposite the bottom 23.

[0071] Here, the guide 24 comprises a first groove 32 and a second groove 34, which pass radially through the wall of the body 26. The grooves 32, 34 are arranged diametrically opposite one another and extend axially.

[0072] The member 22 comprises a cup 40 which receives the base end 18B of the cosmetic stick forming the applicator element 18 .

[0073] The cup 40 is intended to be mounted so that it can be positioned in the guide 24 as shown in FIG. Figure 6 The extreme retracted position shown is similar to Figure 7 The spring 18a and 18b are axially slidable between the shown extreme extended positions, in which the spring is retracted, and in which the free end 18A of the spring projects through the opening 30 .

[0074] The cup 40 comprises two lugs 42 projecting radially outwards. Each lug 42 engages in one of the grooves 32, 34 in the guide 24.

[0075] The cup 40 comprises an axial cylindrical wall 44 . The wall 44 delimits a receiving housing 46 for receiving the base end 18B of the rod forming the applicator element 18 .

[0076] The mechanism 22 includes a sheath 50. As shown therein, the sheath 50 includes a tubular wall 51 having an axis "A".

[0077] The interior of the sheath 50 comprises two diametrically opposed grooves 52 , 54 with which the free ends of the lugs 42 on the cup 40 cooperate during operation.

[0078] The guide 24 is mounted to rotate in the sheath 50 about the main axis “A”. The guide 24 is therefore received concentrically within the sheath 50 .

[0079] exist Figure 4 and Figure 5 In the illustrated embodiment, the collar portion 66 on the body 26 is designed to resiliently snap onto the protrusion 64 on the sheath 50 to axially attach the sheath 50 and the guide 24 .

[0080] In this mechanism 22, the rotation of the guide 24 relative to the sheath 50 by means of its hub 28 results in an axial movement of the cup 40, more precisely, in an upward or downward movement of the cup 40, depending on the direction of rotation. When the cup 40 occupies its extreme extended position, the upper part of the cup 40 here extends axially beyond the sheath 50.

[0081] The cosmetic stick and the cup-shaped portion 40 move axially between an extreme extended position and an extreme retracted position.

[0082] This is a non-limiting example of an applicator assembly 14. The housing 16 may also be used in combination with other types of applicator assemblies 14, including cosmetic sticks (eg, non-guided mechanisms).

[0083] The coating device 10 further includes a tubular storage housing 16 that is separate from the coating assembly 14 .

[0084] The following reference Figures 8 to 11 The housing 16 is described. The housing 16 has a tubular shape extending along a main axis "B". The housing 16 has an end edge 70 defining an opening 72 and an opposite end closed by a bottom 74. The housing 16 is intended to coaxially receive the coating assembly 14 via the free coating end 18A of the coating assembly 14. Thus, when the coating assembly 14 is stored in the housing 16, the axis "A" and the axis "B" coincide.

[0085] The inner shape of the opening 72 is adapted to receive the base 20 with a radial clearance that enables the base 20 to slide axially.

[0086] like Figures 8 to 11 As shown, the slide 76 is axially slidably mounted in the storage housing 16. The slide 76 has an upwardly open receiving portion 78. The receiving portion 78 is intended to receive the free end of the coating assembly 16. The slide includes means for holding the coating assembly 16 in the storage position. For example, the components of the coating assembly 16 are held frictionally interlocked with the slide 18.

[0087] The housing 78 is radially delimited by a cylindrical wall 80 having an axis “B” and by a bottom 81 .

[0088] In the example shown in the figures, when the applicator element 18 is in its extreme retracted position, the sheath 50 is frictionally interlocked in the sliding portion 76 . To this end, the inner surface of the cylindrical wall of the housing 78 has a shape complementary to that of the sheath 50 .

[0089] The inner surface of the cylindrical wall 80 is also provided with a buffer 79 which enables friction against the sheath 50 with a friction force sufficient to hold the applicator assembly 14 and low enough to allow the user to remove the applicator assembly 14 from the slide 76 with his fingers. The buffer 79 is mounted on a portion of the wall 80 that is elastically deformable in the radial direction so that the friction is not too high. The buffer 79 is provided on both sides with two grooves which enable the wall 80 to be given the desired elasticity.

[0090] The sliding portion 76 can be Fig.10 The extreme retracted position shown is Fig.11 The housing 16 is mounted in a sliding manner between the extreme use positions shown.

[0091] When the applicator assembly 14 is in its storage position and the slide 76 is in its extreme retracted position, the base 20 is pushed axially into the housing 20 to prevent the base from being grasped, such as Figure 1 shown.

[0092] Moreover, in this position, the housing 16 makes it possible to protect the cosmetic product by blocking the opening 30 of the mechanism. This makes it possible to prevent contaminant particles from coming into contact with the cosmetic product.

[0093] exist Figure 1 In the example shown, the bottom 23 of the base 20 protrudes slightly axially relative to the end edge 22 of the housing 16 , but not enough to be gripped by fingers.

[0094] Alternatively, not shown, the bottom 23 of the base 20 is flush with the edge 22 of the housing 16 .

[0095] In another variant that is not shown, the base 20 is pushed completely into the housing 16 , below the edge 22 .

[0096] When the applicator assembly 14 is in its storage position and the slide 76 occupies its extreme use position, the base 20 protrudes axially from the lower end edge 22 so that the base can be grasped with the fingers to remove the applicator assembly from the housing 16, as shown in FIG. Figure 2 shown.

[0097] The housing 16 includes a control mechanism for controlling the sliding of the sliding portion between the extreme retracted position and the extreme use position of the sliding portion. To this end, the housing 16 includes at least two tubular extensions 16A, 16B. In particular, the housing 16 is axially divided into two tubular extensions 16A, 16B.

[0098] The upper extension 16A forms an annular portion, which includes an upper opening 72 and is open toward the bottom. The lower extension 16B includes a bottom 74 and is open toward the top. The axial length of the upper extension 16A is shorter than the axial length of the lower extension 16B.

[0099] The extensions 16A, 16B are mounted such that they can rotate relative to each other about a main axis "B". The extensions 16A, 16B are axially fixed relative to each other.

[0100] The upper extension 16A includes a cylindrical wall 80 having an axis "B" radially bounded by an outer surface 80A and an inner surface 80B.

[0101] Lower extension 16B also includes a cylindrical wall 82 having an axis "B" radially bounded by an outer surface 82A and an inner surface 82B.

[0102] For aesthetic reasons, the outer surfaces 80A, 82A of the extensions 16A, 16B are arranged in axial alignment with each other when the extensions 16A, 16B are assembled. As a result, the housing 16 has a smooth outer surface despite the presence of two extensions 16A, 16B.

[0103] The upper extension 16A is mounted on the lower extension 16B by elastic interlocking of complementary shaped elements. Thus, the lower extension 16B has an upper skirt 84 extending from the upper end of the lower extension 16B. The radial thickness of the skirt 84 is less than the radial thickness of the cylindrical wall 82, and therefore the outer diameter of the skirt 84 is less than the outer diameter of the cylindrical wall 82. The skirt 84 is delimited axially downward by a shoulder 86 on the cylindrical wall 82 and axially upward by a free edge 88.

[0104] This skirt 84 is intended to be inserted axially into an annular recess 90 formed in the inner surface 80B of the upper extension 16A to assemble the lower extension 16B with the upper extension 16A. Thus, the lower end edge 92 of the wall 80 of the upper extension 16A abuts against the shoulder 86 of the lower extension 16B.

[0105] To enable attachment by elastic interlocking, the outer surface of the skirt 84 of the lower extension 16B and the inner surface of the recess 90 of the upper extension 16A are provided with at least one other annular valley 94 receiving at least one complementary protrusion 96. This type of interlocking enables the upper extension 16A to be axially attached to the lower extension 16B while enabling the upper and lower extensions to rotate relative to each other about the main axis "B".

[0106] The control mechanism for controlling the sliding movement of the sliding portion 76 includes a member for converting the relative rotational movement of the extending portions 16A, 16B into the sliding movement of the sliding portion 76 .

[0107] To this end, the slide 76 is guided so that it slides axially relative to one of the extensions 16A, 16B, while the slide 76 is guided so that it can be screwed relative to the other of the extensions 16B, 16A.

[0108] In the embodiment shown in the drawings, the sliding portion 76 is guided to slide axially relative to the extension 16A including the upper end edge 70 of the housing 16 .

[0109] The axial sliding guidance is achieved here by engaging at least one axial projection 98 carried by one of the sliding portion 76 or the associated extension 16A in an axial groove 100 carried by the other of the sliding portion 76 or the associated extension 16A.

[0110] Each projection 98 is carried by the slide 76 .

[0111] The slide 76 has at least one protrusion 98 protruding radially from the outer surface of the cylindrical wall 80. Each protrusion 98 is formed by an axial rib extending radially from the outer surface of the cylindrical wall 80 of the slide 76. The protrusion 98 is integral with the slide 76.

[0112] The sliding portion 76 has a plurality of (eg, four) identical protrusions 98 evenly distributed around the axis “B”. Each protrusion 98 extends along a main axial direction. The protrusion 98 is arranged near the upper end of the sliding portion 76.

[0113] The projections 98 are intended to be received in complementary axial guide grooves 100 formed in the inner surface 80B of the cylindrical wall 80 of the upper extension 16A. Each groove 100 is closed at the top and opens axially downwards into the recess 90.

[0114] In a variant of the invention that is not shown, the projection is carried by the upper extension and the groove is carried by the sliding portion.

[0115] In this case, the slide 76 is screw-guided relative to the lower extension 16B. The screw-guiding is achieved by engaging at least one radial lug 102 carried by one of the slide 76 or the associated extension 16B in a helical groove 104 carried by the other of the slide 76 or the associated extension 16B.

[0116] In the embodiment shown in the drawings, at least one lug 102 is carried by the sliding portion 76. The sliding portion 76 is equipped with a plurality of lugs 102. The lugs 102 are evenly spaced about the axis "B". As a non-limiting example, the sliding portion 76 includes two lugs 102 that are diametrically opposed relative to the axis "B".

[0117] The associated helical grooves 104 are carried by the lower extension 16B. The lower extension 16B is provided with at least as many helical grooves 104 as lugs 102 carried by the sliding part 76.

[0118] To facilitate assembly of the housing 16, the lower extension 16B is provided with a plurality of spiral grooves 104, the number of which is a multiple of the number of lugs 102. The lower extension 16B has four spiral grooves 104, and only two of the four spiral grooves actually cooperate with the lugs 102.

[0119] Each screw guide lug 102 is spaced apart from the axial guide protrusion 98 .

[0120] The helical groove 104 and the associated lug are axially arranged in the housing 16 between the bottom 74 of the housing 16 and the bottom 81 of the slide 76. Thus, when the applicator assembly 14 is stored in the housing 16, the helical groove 104 is axially inserted between the applicator assembly 14 and the bottom 74 of the housing 16, regardless of the position of the slide 76.

[0121] To this end, the lower extension 16B includes an insert 106 that extends concentrically upward from the bottom 74 within the housing 16. A spiral groove is formed in the inner surface 108 of the insert 106. The insert 106 is located below the bottom 81 of the sliding portion 76, and each lug 102 is carried by a rod 110 located at the axial end of the sliding portion 76 regardless of the axial position of the sliding portion. The rod 110 extends axially downward from the bottom 81 of the sliding portion 76. The rod 110 extends along the axis "B" of the housing 16.

[0122] When assembling the housing 16, the rod-shaped portion 110 of the slide 76 is screwed into the insert 106. The wall 80 of the slide 76 is equipped with elastically flexible legs 112A, 112B, which have free ends 114A, 114B protruding radially outward. Each flexible leg 112A, 112B is preloaded so that the free protruding ends 114A, 114B permanently rub against the inner surface of the lower extension 16B.

[0123] In this manner, the slide 76 is held in the center of the lower extension 16B. In this position, the upper portion of the slide 76 including the protrusion 98 projects axially upward relative to the upper edge 88 of the lower extension 16B.

[0124] Legs 112A, 112B also make it easier to use by creating a braking force that prevents sliding of slider 76 in two orientations. This braking force is of course much less than the sliding force generated by rotating extensions 16A, 16B relative to each other by hand.

[0125] Furthermore, the slide 76 comprises at least two legs 112A, 112B, the free ends 114A, 114B of which are arranged at two different heights. The first inner surface 82B of the lower extension comprises an annular valley 116. The legs 112A, 112B and the valley 116 are arranged so that when the slide 76 occupies the extreme retracted position of the slide, the free protruding end 114A of the upper leg 112A snaps elastically into the valley 116, as shown in FIG. Fig.10 When the slide 76 occupies the extreme use position of the slide, the free protruding end 114B of the lower leg 112B is elastically snapped into the valley 116, as shown in FIG. Fig.11 Thus, the tactile and / or auditory perception of the snap enables the user to feel that the slide 76 has reached one of the slide's limit positions.

[0126] Thus, the upper extension 16A interlocks with the lower extension 16B to surround the protruding portion of the slider 76. At the same time, the protrusion 98 is axially inserted into the axial groove 100. The upper extension 16A elastically interlocks with the skirt 84 of the lower extension 16B. Thus, the axial travel of the slider 76 is limited toward the top in one orientation by the contact of the lug 98 with the closed upper end of the groove 100, and is limited toward the bottom by the contact of the lug 98 with the free edge 88 of the skirt 84.

[0127] Advantageously, all components of the housing 16 are made of the same material, for example a plastic material such as polypropylene (PP) or polyethylene terephthalate (PET). This makes it easier to recycle the housing 16.

[0128] Advantageously, all components of the applicator assembly 14, except the cosmetic, are made of the same material, for example a plastic material such as polypropylene (PP) or polyethylene terephthalate (PET). This makes it easier to recycle the applicator assembly 14.

[0129] Advantageously, all components of the applicator assembly 14 and the housing 16, except the cosmetic, are made of the same material. For example, a plastic material such as polypropylene (PP) or polyethylene terephthalate (PET). This makes it easier to recycle the entire device 10 formed by the housing 16 and the applicator assembly 14.

[0130] Alternatively, the components of the housing 16 may be made of different thermoplastic materials, provided that the materials can be recycled together in the same recycling channel. Examples include polypropylene (PP) and polyethylene terephthalate (PET). For example, some components may be made of PP while other components are made of PET.

[0131] Reference Figure 1 , Figure 2 , Figure 3 , Fig.12 and Fig.13 The use of the coating device 10 is described. When using the coating device 10, the user holds the housing 16 storing the coating assembly 14, such as Figure 1 The user rotates the lower extension 16B relative to the upper extension 16A. This causes the slide 76 to rotate from Figure 1 and Fig.12 The sliding portion shown in FIG. 1 is slid to the limit retracted position as shown in FIG. Figure 2 and Fig.13 The slide portion 76 then abuts against the upper end of the axial groove 100 .

[0132] The user can then access the base 20. The user pulls the base 20 with one hand while holding the housing 16 with the other hand to overcome the friction provided by the buffer portion 79 of the sliding portion 76 to remove the coating assembly 14. Once the coating assembly 14 is completely removed, as shown in FIG. Figure 3 As shown, the user can apply cosmetics freely.

[0133] After use, the coating assembly 14 is inserted into the slide 76 again by the coating end of the coating assembly 14. Then, the extensions 16A, 16B of the housing 16 are rotated relative to each other to lower the slide 76 to the extreme retracted position of the slide. The buffer 79 enables the coating assembly 14 to be held in the slide 76 during sliding. The base 20 is thus protected by the housing 16 to prevent any unintentional manipulation of the coating assembly 14.
