Description

Title of the invention: DEVICE FOR APPLYING A COSMETIC PRODUCT, IN PARTICULAR A COSMETIC PRODUCT STICK Technical field of the invention

[0001] The invention relates to a cosmetic product application device, in particular a cosmetic product stick, comprising a cup carrying the cosmetic product and intended to be inserted into a guide of an application device. Technical background

[0002] Prior art is known for application devices used for packaging a cosmetic product, such as a cosmetic stick, particularly but not exclusively for a lipstick or deodorant stick. Such a cosmetic stick may also be referred to as a "stick".

[0003] The stick 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 stick extends axially out of the device.

[0004] The assembly and disassembly of all the parts constituting the application device can be complex in particular because of lugs protruding radially outwards present on the cup and allowing axial sliding of the latter causing the exit and entry of the cosmetic product.

[0005] There are also cups which are mounted in a removable manner, with or without the sliding mechanism, in the device and form a refill intended to equip a cosmetic product application device and to be able to be removed when the user wishes.

[0006] The use of a removable system makes it possible to retain certain parts of the application device.

[0007] This could be, for example, a cap and a base for the application device. The guide, the sheath, and the cup must then be replaced along with the cosmetic product stick. This is particularly advantageous when the cap and / or the base are made of precious and / or decorated materials, for example, covered with a protective coating, which makes them comparatively more expensive to manufacture.

[0008] In other types of application devices, only the cup is a replaceable component. The cup is then designed to allow the cosmetic product stick to be replaced when it is empty. Here again, the gesture for Replacing the cup remains complex and is not always easy, particularly because of the lugs present on it.

[0009] Furthermore, depending on the height differences between the old cosmetic product stick and the new cosmetic product stick, the user may have to make several rotations of the mechanism to move the cosmetic product stick carried by the new cup from the low position to the high position of use, or vice versa, to have the stick in the appropriate position.

[0010] Thus, there is a need for a solution that resolves at least some of the disadvantages of the prior art. Summary of the invention

[0057] By convention, the "axial" or "longitudinal" direction corresponds in the figures to that of the main axis A of the cosmetic product application device 10, such as a cosmetic product stick 12, in particular a lipstick or deodorant stick, and the "radial" or "transverse" direction is directed orthogonally to the axial direction by radiating from the main axis (A).

[0058] 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 application device 10 corresponding to that through which the stick 12 of cosmetic product comes out of the application device 10 for application.

[0059] 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.

[0060] Subsequently, elements having an identical structure or analogous functions will be designated by the same reference.

[0061] Figures 1 to 4 illustrate a cosmetic product application device 10 in the form of a cosmetic product stick 12.

[0062] Preferably, the cosmetic product stick 12 (visible in figures 1 and 2) is a lipstick stick or a deodorant intended to be applied by rubbing, alternatively a lip balm.

[0063] The device 10 is designed to expel the cosmetic product by at least one rotational movement.

[0064] The device 10 has an axis A, called the principal axis.

[0065] Device 10 comprises:

[0066] - a cup 14 intended to receive the rod 12,

[0067] - at least one guide 16, and

[0068] - a tubular sheath 18.

[0069] The guide 16 is particularly visible in figures 6 and 7.

[0070] The guide 16 mainly comprises a tubular body 20 which extends axially from a lower opening 22 for insertion of the cup 14 to an upper outlet opening 24 intended to be traversed by the stick 12 of cosmetic product.

[0071] Advantageously, the guide 16 further comprises a base 26 in the extension of the lower opening 22 of the tubular body 20.

[0072] The guide 16 has at least one axial slot 28 radially passing through the wall of the body 20. Each axial slot 28 forms a slide.

[0073] Here, the guide 16 comprises two axial slots 28. The axial slots 28 are arranged diametrically opposite each other.

[0074] The axial slots 28 extend axially into the body 20 of the guide 16 from the bottom of the guide 16.

[0075] Each of the axial slots 28 opens at the upper opening 24. In other words, each axial slot 28 is axially open at its upper end 28a. The axial slots 28 are closed at their lower end 28b located on the side of the base 26.

[0076] The axial slots 28 each have straight and parallel edges.

[0077] Each of the axial slots 28 of the guide 16 is extended at the bottom of the guide 16 by at least one lower guide ramp 30 visible in [Fig.7].

[0078] Each of the lower guide ramps 30 has a shoulder 30a extending from a low point located at the bottom of the base 26 to a high point located at the lower end 28b of an axial slot 28. Each of the shoulders 30a extends into one of the straight edges forming the axial slots 28.

[0079] Each of the axial slots 28 of the guide 16 is extended at the top of the guide 16 by at least one upper guide ramp 32.

[0080] Each of the upper guide ramps 32 is in the extension of one of the straight edges forming the axial slot 28 and extends to a high point forming an upper edge 34 delimiting the upper opening 24 exiting the rod 12.

[0081] Here, each axial slot 28 comprises two upper guide ramps 32 and two lower guide ramps 30. The guide 16 therefore comprises four upper guide ramps 32 and four lower guide ramps 30.

[0082] The cup 14 is intended to be mounted sliding axially in the guide 16, between a retracted extreme position, as shown in [Fig.1], and a deployed extreme position, not shown.

[0083] The extreme retracted position corresponds to a position in which the rod 12 is inside the device 10 for its protection and storage and the cup 14 is in the lower end-of-stroke position as illustrated in [Fig.1].

[0084] The extreme deployed position corresponds to a position in which the rod 12 is deployed axially upwards so that its free end extends out of the device 10 through the opening and the cup 14 is in the upper end-of-travel position.

[0085] The cup 14 can also occupy intermediate positions between its two extreme retracted and deployed positions, called intermediate application positions.

[0086] With reference to [Fig.5], the cup 14 has at least one lug 36, preferably two lugs 36. Each lug 36 protrudes radially outwards, said lugs 36 being each engaged in one of the axial slots 28 of the guide 16 and passing through them to extend radially outwards beyond the external cylindrical surface of the body 20 of the guide 16.

[0087] Preferably, the lugs 36 are diametrically opposed.

[0088] The cup 14 has a housing 38 for receiving the cosmetic product stick 12, radially delimited by a cylindrical lateral wall 40. The housing 38 is open upwards.

[0089] Housing 38 is axially delimited downwards by a base which extends radially inwards from the side wall. The base is pierced by an orifice.

[0090] The cupule 14 has at least one leg 42 formed in the lateral wall and having a connecting end 42a to the lateral wall and a free end 42b, the at least one lug 36 being located on a leg 42. Each leg 42 extends axially downwards from its connecting end 42a to its free end 42b.

[0091] In the embodiment illustrated in [Fig.5], the cup 14 comprises two diametrically opposed legs 42 distributed regularly around the main axis A, the two legs 42 each comprising one of the two lugs 36.

[0092] Preferably, each leg 42 is made from a single piece of material with the side wall 40. They are formed by a notch made in the side wall of the cupule 14, for example, as here by a notch having a "U" shape.

[0093] In an alternative embodiment of the cup 14 shown in figures 15 and 16, the cup 14 differs in that it does not have openwork legs 42 but only lugs 36. The flexibility of movement of the lugs 36 can be achieved through the choice of material, for example.

[0094] Advantageously, the cup 14 includes an internal skirt 44 for attaching the stick 12 which protrudes axially into the housing 38 from the bottom.

[0095] The inner skirt 44 includes lights 46 to improve the grip of the stick 12.

[0096] With reference to [Fig. 8], the sheath 18 has a tubular wall 48 with axis A main.

[0097] The sheath 18 has internally at least one helical groove 50 for receiving at least one associated lug 36 of the cup 14. Each of the helical grooves 50 is open at the upper end of its stroke.

[0098] The sheath 18 here has two helical grooves 50, diametrically opposed, with which the free ends of the lugs 36 of the cup 14 cooperate in operation.

[0099] In addition, as illustrated in [Fig. 14], the helical groove 50 of the sheath 18 may include a starter 51 allowing the lugs 36 of the cup 14 to position themselves more easily in the helical groove 50 when inserting the cup 14 into the device 10.

[0100] The wall 48 of the sheath 18 has an internal cylindrical face provided with said helical grooves 50.

[0101] The wall 48 of the sheath 18 also has an external cylindrical face comprising a screw thread 52 extending over an upper portion of the sheath 18. The rest of the external face is smooth.

[0102] Rotating the guide 16 relative to the sheath 18 causes an axial movement of the cup 14 between the extreme deployed position and the extreme position retracted, and vice versa, that is to say the entry and / or exit of stick 12 of cosmetic product.

[0103] In the illustrated embodiment, the rotation is advantageously carried out by the user by gripping the base 26 and rotating the guide 16 relative to the sheath 18.

[0104] The axial slots 28 of the guide 16 opening at the level of the upper opening 24 thereof, as well as the helical groove 50 open at the end of the upper stroke, allow the total removal of the cup 14.

[0105] Indeed, classically the axial slots are closed axially at their upper end, or even include a notch, so as to block the cup at the end of the upper stroke.

[0106] In the application device 10 according to the invention, nothing blocks the cup 14 at the end of its upper stroke; it can then be easily removed by a simple gesture, without requiring any tools and without damaging the other elements, in particular the sheath 18 and the guide 16.

[0107] This removal method is also particularly advantageous because it eliminates the need for the user to push the cup 14 all the way down to remove it, as is required in other known devices. Removal does not require any additional steps from the user, who can quickly remove the cup 14 and thus avoid wasting time on tedious movements.

[0108] Removing the cup 14 can be useful, for example, when recycling the device 10 where each element may need to be disassembled to be recycled in its own stream depending on the material it is made of.

[0109] Removing the cup 14 can also allow it to be replaced, for example, when the cosmetic product stick 12 is finished or if the user wishes to change it.

[0110] Advantageously, the upper guide ramps 32 allow the lugs 36 of the cup 14 to be guided to the end of its travel, in particular in relation to the sheath 18 when the lugs 36 come out of the axial slots 28 of the guide 16.

[0111] The cup 14 can thus reach its end of travel, in particular the upper end of travel of the helical groove 50 of the sheath 18 by means of its lugs 36 which are guided by the upper guide ramps 32. The cup 14 is then held in position until the end without risk of it coming loose or getting stuck sideways.

[0112] On the other hand, the lower opening 22 of the guide 16 allows the cup 14 to be inserted from the bottom of the device 10.

[0113] Thus, the upper end of the cosmetic product stick 12 is inserted first into the device 10 through the lower opening 22 of the guide 16 so that the stick 12 is immediately inside the device 10 and thus protected from any deterioration or contamination that could occur during the assembly of cup 14.

[0114] Furthermore, by inserting the cup 14 from the bottom of the device 10, it is directly in the fully retracted position. The user therefore does not need to perform any additional steps, for example, lowering the cup 14, to place it in the position where the cosmetic product stick 12 is inside the device 10.

[0115] Inserting the cup 14 can be useful, for example, when assembling the device 10 or when changing the cosmetic product stick 12 after its removal when it is completely consumed or if the user wishes to change it.

[0116] Advantageously, the lower guide ramps 30 allow the lugs 36 of the cup 14 to be guided to the axial slots 28 of the guide 16. Thus, when the user inserts the cup 14 through the lower opening 22 of the guide 16, the lugs 36 cooperate with the lower guide ramps 30 until they are positioned in one of the two axial slots 28. The guide ramps thus facilitate the insertion of the cup 14 into the guide 16, thereby preventing damage to the cosmetic product stick 12, which can occur if the user has difficulty aligning the lugs 36 of the cup 14 with the axial slots 28 of the guide 16.

[0117] Advantageously, to facilitate the insertion of the cup 14 into the guide 16 and also to ensure its retention therein, each tab 42 is flexible between:

[0118] - an unconstrained position in which each lug 36 is radially projecting outwards relative to the lateral wall 40 of the cupule 14;

[0119] - an insertion position of the cup 14 in the device 10 in which each The tab 42 is intended to be pushed by contact between a lug 36 and the guide 16 and to penetrate radially into the housing 38 so that each lug 36 is in alignment with the lateral wall 40.

[0120] Preferably, the legs 42 extending axially downwards from its connecting end 42a to its free end 42b.

[0121] Moreover, each lug 36 advantageously has a front surface 36a inclined relative to the side wall 40, a lower portion 36b of the lug 36 having a wider thickness than an upper portion 36c of the lug 36 (see figures 1 and 3).

[0122] Thus, the tabs 42 are radially moved into the device 10 when the user inserts the cup 14 and return to their original position when the cup 14 is correctly inserted.

[0123] Advantageously, the movement of the legs 42 is facilitated by the particular shape of the lugs 36. Indeed, the upper portion 36c of the lug 36, having a low thickness, fits more easily into the corresponding axial slot 28.

[0124] On the contrary, the wider lower portion 36b of the lug 36 comes into contact with the guide 16 when the cup 14 is lowered, blocking its descent and exit from the guide 16 through the lower opening 22.

[0125] Advantageously, the cup 14 is mounted removably in the device 10. The cup 14 can be easily inserted into the device 10 through the lower insertion opening 22 of the guide 16 and / or removed from the device 10 through the upper opening 24 of the guide 16 as explained above.

[0126] Advantageously, the cosmetic product stick 12 mounted on the cup 14 has a lower portion that is flexible in a similar way to the legs 42. Insertion of the cup 14 is facilitated and movement of the legs 42 into the device 10 is not hindered.

[0127] Preferably, the device 10 includes a lower cap 54 for closing the lower opening 22 for inserting the guide 16. The lower cap 54 is in particular a removable cap.

[0128] With reference to [Fig. 9], the lower cap 54 is clipped to the guide 16. Its axial retention on the lower opening 22 of the guide 16 is ensured by the cooperation of two external annular ridges 56 of the lower cap 54 with two internal annular grooves 58 located in the bottom of the guide 16 (visible in [Fig. 7]). The ridges 56 and the grooves 58 are diametrically opposed, respectively.

[0129] The lower cap 54 has a first annular housing 60 delimited by two internal circular axial skirts 62 into which a lower edge 64 of the cylindrical lateral wall 40 of the cup 14 is inserted when it is in the extreme retracted position (visible in figures 3 and 4).

[0130] The lower cap 54 also includes a circular axial outer skirt 66 having an external surface on which the ridges 56 mentioned above are located. This outer skirt 66 is inserted inside the guide 16 at the lower opening 22.

[0131] The internal skirts 62 and external skirts 66 extend from a closed transverse lower bottom 68 towards respective upper edges.

[0132] The upper edge 70 of the outer skirt 66 has a shape complementary to the shape delimited by the lower ramps 30 of the guide 16 against which it comes to rest when inserted.

[0133] This complementarity of form is visible, for example, by comparison of figures 7 and 11 illustrating two variant embodiments of the guide 16 according to the design of the upper edge 70 of the lower cap 54, the guide 16 of [Fig.7] being the associated guide of the lower cap 54 of [Fig.9] and the guide 16 of [Fig.11] being the associated guide of the lower cap 54 of [Fig.10].

[0134] As illustrated in figures 1 to 4, the device 10 can finally include a top cap 72 intended to close a top exit opening of the rod 12 of the sheath 18.

[0135] The upper cap 72 is in particular a removable cap.

[0136] The upper cap 72 has a tubular skirt closed at its end upper by a solid transverse wall.

[0137] It is preferable to be able to close the device 10 using the upper cap 72 in order to avoid contaminating or damaging the cosmetic product stick 12. In this regard, the upper cap 72 is intended to be fixed directly to the outer wall of the sleeve 18 when the device 10 is not in use, covering at least an upper portion of the outer face of the sleeve 18.

[0138] Advantageously, the upper cap 72 is screwed to the sheath 18. Thus, the upper portion of the external face of the sheath 18 cooperates with an internal screw thread 74 disposed on the internal face of the tubular skirt of the upper cap 72.

[0139] Advantageously, at least one of the cup 14, guide 16, sheath 18, lower cap 54 and upper cap 72 is made of plastic material, such as recycled or non-recycled polypropylene (PP) or polyethylene terephthalate (PET), or of metallic material, such as aluminium.

[0140] Advantageously, at least one of the cup 14, the guide 16, the sheath 18, the lower cap 54 and the upper cap 72 are advantageously made of the same material, for example of plastic.

[0141] Furthermore, the use of plastics, in particular similar plastics, for the entire device 10 facilitates recycling. In particular, polypropylene and polyethylene terephthalate are two plastics whose recycling cycle is well known.

[0142] Preferably, at least one of the cup 14, guide 16, sheath 18, lower cap 54 and upper cap 72 is made by molding.

[0143] The invention is not limited to the description just given; other embodiments may fall within the scope of the invention.

[0144] For example, figures 10 and 12 illustrate a second and a third embodiment of the lower cap 54 comprising, alternatively, different connecting means.

[0145] By way of illustration and as shown in [Fig. 10], in a second embodiment, the lower cap 54 has two locking clips 75 in the form of elastically deformable hooks. The two clips 75 cooperate with the recesses 58 located in the bottom of the guide 16 illustrated in [Fig. 11]. Thus, insertion is facilitated by the shape and elasticity of the hooks, and removal of the cap is also facilitated. lower 54, voluntary or untimely, is limited since it is necessary to exert simultaneous pressure on the area of ​​the hooks to disengage them and therefore release them.

[0146] Another alternative to the technical realization of the lower cap 54, shown in [Fig. 12], consists of a bayonet locking mechanism, a design well known to those skilled in the art. The lower cap 54 comprises two diametrically opposed L-shaped recesses 76, each of which cooperates with a rib 78 located in the bottom of the guide 16 as illustrated in [Fig. 13].
