Description

Title of the invention: REFILLABLE COSMETIC PRODUCT PACKAGING DEVICE technical field

[0001] This disclosure falls within the domain of refillable cosmetic product packaging devices. Previous technique

[0002] In the cosmetics field, in particular, users are especially sensitive to the aesthetics of packaging devices. However, the cost of aesthetically pleasing packaging devices is high and consequently increases the price of cosmetic products sold in this form commercially.

[0003] An idea emerged consisting of providing a packaging device comprising an attractive case and a refill, possibly less attractive than the case, but with less expensive packaging. The refill is advantageously removable, so that the packaging device can be refilled by replacing the single removable refill in the case.

[0004] Such a refillable packaging device may have an improved environmental footprint because only the refill is discarded when the cosmetic product is exhausted.

[0005] However, in this case, some users try to use the cosmetic product refill without the case. By doing so, the cosmetic product is less well packaged. Indeed, the refill is not designed to withstand significant impacts, since the case protects the refill within the packaging device.

[0006] There is therefore a need to limit or even prevent a cosmetic product refill from a cosmetic product packaging device from being used without the associated packaging device case. Summary

[0007] To this end, a packaging device for a cosmetic product is proposed, comprising: - a cosmetic product refill containing: — a reservoir suitable for holding cosmetic products, the reservoir having a neck fitted with a thread, — a cap with a threaded hole for screwing onto the neck of the tank, and — a sleeve mounted to rotate freely around the cap, And - a cover attached to the cap, The cap and the cover comprise complementary ridges that cooperate to make the cap and cover rotationally fixed around the axis of the thread and tapping.

[0008] Thus, advantageously, the cosmetic product refill cannot be easily opened until it is received in the cover of the packaging device. This encourages users to use the cosmetic product refill only when it is received in the cover of the cosmetic product packaging device.

[0009] According to preferred embodiments, the conditioning device may have one or more of the following characteristics, taken alone or in combination: - the plug has a generally cylindrical shape, extending along the direction of the thread axis and the tapping, - the socket has a generally cylindrical shape, extending along the direction of the thread axis and the tapping, the cylindrical surface of the socket covering the entire cylindrical surface of the cap; - the plug has at least one first relief in the vicinity of a first longitudinal end, the sleeve has at least one second relief, preferably in the vicinity of a first longitudinal end, the first and second reliefs cooperating to limit or even prevent the movement of the plug relative to the sleeve, in a first direction along the direction of the axis of the thread and the tapping; - one of the first and second reliefs is a radially projecting circular edge and the other of the first and second reliefs is a complementary circular recess; - the plug has at least a third relief in the vicinity of a second longitudinal end, the sleeve has a fourth relief, preferably in the vicinity of a second longitudinal end, the third and fourth reliefs cooperating to limit or even prevent the movement of the plug relative to the sleeve, in a second direction along the direction of the axis of the thread and the tapping, the second direction being opposite to the first direction; - one of the third and fourth reliefs is a radially projecting circular edge and the other of the third and fourth reliefs is a complementary circular recess; - the tank has at least one lug received in a notch in the cap to hold the cap in position, once screwed onto the tank; - the additional reliefs include at least one first recessed relief, on one of the two parts being the cap and the hood, and at least one second projecting relief complementing comment on the other between the cap and the hood; - the complementary reliefs consist of a single first recessed relief, on one of the cap and the hood, preferably on the cap, and a single second complementary raised relief on the other of the cap and the hood, preferably on the hood; - the first and second reliefs are generally cylindrical in shape, extending along the direction of the axis of the thread and tapping, the first and second reliefs being of non-circular cross-section; - the additional reliefs consist of at least one first recessed relief, preferably at least two first recessed reliefs, on one between the plug and the hood, preferably again on the plug, and at least one second complementary protruding relief on the other between the plug and the hood, preferably at least two second complementary protruding reliefs on the other between the plug and the hood, preferably again on the hood, the at least one first recessed relief and the at least one second protruding relief being offset with respect to the axis of the thread and the tapping; - each second relief is elastically fitted or force-fitted into a first associated relief; - the cap is attached to an applicator element; - the applicator element is connected to the cap by means of a rod so that it is received in the reservoir when the cap is screwed onto the neck; - the packaging device is devoid of any cosmetic product application device and any cosmetic product distribution device; - the conditioning device further includes a base formed by a casing defining a housing receiving the reservoir of the refilling device; - the reservoir and the casing include additional elastic interlocking reliefs to fix the reservoir in the housing in the casing, in particular to limit or even prevent movement of the reservoir in the housing along the axis of the thread and tapping; - the tank and the casing include complementary reliefs cooperating to make the tank and the casing rotationally fixed around the axis of the thread and tapping; - the additional reliefs include ribs on one between the tank and the cladding shell and additional grooves on the other between the tank and the cladding shell, the additional ribs and grooves preferably extending parallel to the axis of the thread and tapping; - the grooves have a flared opening; and - the plug includes a sleeve in which the threading is preferably made and a cap head rigidly fixed to the sleeve, for example by elastic fitting.

[0010] According to another aspect, a cosmetic product refill for a packaging device as described above is proposed, in all its combinations, comprising: - a reservoir suitable for holding cosmetic products, the reservoir having a neck fitted with a thread, - a cap with a threaded hole for screwing onto the neck of the tank, and - a sleeve mounted to rotate freely around the cap, the cap comprising a relief adapted to cooperate with a complementary relief of a hood of the packaging device to make the cap and the hood rotationally fixed around the axis of the thread and tapping.

[0011] The cap may comprise a single relief of generally cylindrical shape, extending along the direction of the thread and tapping axis, the only relief being of non-circular cross-section.

[0012] Alternatively, the plug may comprise at least one ridge, each ridge being generally cylindrical in shape, extending along an axis parallel to the direction of the thread and tap axis, the axis of each ridge being distinct from the thread and tap axis. The plug may preferably comprise at least a first and a second ridge, the first and second ridges being symmetrical to each other with respect to the thread and tap axis.

[0024] In the remainder of this description, identical elements or elements with identical functions are designated by the same reference numeral. For the sake of brevity, elements that are identical in several examples are not described in detail within the detailed description of each of those examples. Instead, the following description primarily details the differences between the various examples.

[0025] Figure 1 schematically represents, in perspective, a first example of a cosmetic product packaging device 10. According to this first example, the cosmetic product is in a form suitable for packaging in a reservoir. For example, the cosmetic product is in the form of a liquid, a gel, a cream, or a powder. The cosmetic product may, in particular, be a lipstick, a lip gloss, a skin or lip care product, especially a lip balm, a sunscreen product for the lips or skin, a cosmetic product for the eyelids or eyelashes, or a nail polish. The cosmetic product is, in particular, a mascara.

[0026] According to the example described below, the device 10 is suitable for packaging and applying the cosmetic product in that it allows the cosmetic product to be stored and applied. To this end, the packaging device 10 includes a device for applying the cosmetic product, as will be described later. Alternatively, however, the packaging device 10 may be equipped with a device for dispensing the cosmetic product, such as a pump or a pipette, for example. According to yet another alternative, the packaging device 10 is without any application or dispensing device.

[0027] As illustrated in [Fig. 1] and [Fig. 2], the conditioning device 10 essentially comprises a case 12 and a refill 14. The case 12 here consists of a base 15 and a cover 16. As illustrated, the conditioning device The conditioning and application device 10, particularly the housing 12, is generally cylindrical in shape, extending primarily along the direction of an axis A10 extending from the conditioning and application device 10. Here, the conditioning and application device 10 is generally cylindrical with a square cross-section and rounded corners. Of course, other general shapes of the conditioning and application device 10 are possible. In particular, the conditioning and application device 10 can be generally cylindrical with a circular, elliptical, or polygonal cross-section, including triangular or square.

[0028] The base 15 of the housing 12 is visible in longitudinal section in [Fig.3]. The base 15 of the housing 12 is here formed by a casing 18 which extends mainly along the direction of an axis A18 of extension of the casing 18, corresponding here to the axis A10 in the conditioning and application device 10. Here the casing 18 has a substantially square cross-section.The casing 18 can be made of any material conceivable by a person skilled in the art for forming a casing for a cosmetic product packaging and application device 10, in particular one of the following: glass, metal, in particular aluminium or an aluminium alloy, in particular zamak, ceramic, porcelain, crystal and plastic, in particular polymethyl methacrylate, polystyrene, polycarbonate, polyethylene terephthalate, ionomer resin such as ethylene vinyl copolymer known under the trade name Surlyn®, wood and urea formaldehyde.

[0029] On its radially internal surface, the casing 18 has two ribs 20. The two ribs are arranged symmetrically with respect to the axis A18 of the casing 18. Here, each rib 20 is straight, parallel to the axis A18 of the casing 18. Each rib 20 extends over only a portion of the height of the casing 18, oriented along the direction of the axis A18 of the casing 18. For example, each rib 20 extends over at least half the height of the casing 18, preferably over at least two-thirds of the height of the casing 18, and even more preferably over at least three-quarters of the height of the casing 18, from the bottom 19 of the casing. 18, opposite the outlet of the cladding hull 18.

[0030] The two ribs 20 protrude radially into a housing 22 of generally cylindrical shape, delimited by the cladding shell 18.

[0031] The casing 18 forming the base 15 of the housing 12 also includes, according to the illustrated example, two elastic snap-fit ​​tabs 24 (“elastic snap-fit” or “clip-on”) arranged symmetrically with respect to the axis A18 of the casing 18. Each elastic snap-fit ​​tab 24 extends from the bottom of the casing 18. The two elastic snap-fit ​​tabs 24 are offset an- Approximately around the axis A18 of the housing shell 18 relative to the two ribs 20. Each elastic interlocking tab 24 comprises a flexible, elastically extending tab from the bottom of the housing shell 18 and a rigid, projecting ridge at the free end of the flexible tab. Here, the elastic interlocking tabs 24 are integral with the housing shell 18. Alternatively, the elastic interlocking tabs 24 are attached to the inside of the housing shell 18.

[0032] As can be seen in [Fig. 2], the base 15 is shaped to receive a cosmetic product refill 14 as illustrated in [Fig. 4]. The cosmetic product refill 14 includes, in particular, a reservoir 28 shaped to fit into the recess 22 in the base 15. The reservoir 28, for example, has a cross-section complementary to the cross-section of the recess 22 in the base 15, but is shorter. Here, the reservoir 28 is generally cylindrical in shape.

[0033] The reservoir 28 also has, on its radially external surface, two grooves 30 extending primarily along the direction of the axis A14 of the cosmetic product refill 14. The two grooves 30 are arranged symmetrically with respect to the axis A14 of the cosmetic product refill 14. Each groove 30 extends over only a portion of the height of the reservoir 28, measured along the direction of the axis A14 of the cosmetic product refill. For example, each groove 30 extends over at least half, preferably at least two-thirds, of the length of the reservoir 28, from the bottom of the reservoir 28 intended to be received in the bottom of the housing 22 in the casing 18.

[0034] Each groove 30 has, in the vicinity of the bottom of the reservoir 28, a flared outlet 32.

[0035] The bottom of the reservoir 28 forms a nipple 34, here cylindrical, with axis A14 of the cosmetic product refill 14. On the nipple 34 is formed a circular groove 36.

[0036] Each groove 30 is adapted to receive a rib 20 inside the housing 22 in the base 15 to guide the insertion of the reservoir 28 into the housing 22 in the base 15. The flared opening 32 of the grooves 30 thus facilitates the insertion of the ribs 20 into the grooves 30. The reservoir 28 is fixed in the housing 22 by elastic engagement of the elastic engagement tabs 24 with the stud 34 on the reservoir 28. More precisely, the elastic engagement tabs 24 are deformed during the insertion of the reservoir 28 until the protruding ridges of the elastic engagement tabs 24 are received in the circular groove 36 formed on the stud 34. In this position of the reservoir 28 in the housing 22, the ribs 20 are received inside the grooves 30 allows to limit or even prevent a relative rotational movement of the reservoir 28 with respect to the base 15, around the axis A15 of the base 15.

[0037] The reservoir 28 has an outlet 38, opposite the bottom of the reservoir, at the end of a neck 40. The neck 40 has a thread 42. The thread 42 extends helix around the axis A14 of the cosmetic product refill 14. Thus, the axis of the thread 42 corresponds to the axis A14 of the cosmetic product refill 14. Two lugs 44 are on the front surface of the reservoir 28, substantially perpendicular to the direction of the axis A14 of the cosmetic product refill 14, surrounding the neck 40. The two lugs 44 protrude from the front surface of the reservoir 28 surrounding the neck 40, along the direction of the axis A14 of the cosmetic product refill 14.

[0038] The cosmetic product refill 14 also includes a cap 46 for closing the reservoir 28. Here, the cap 46 is formed of two parts fixed together: - a sleeve 48 having a threaded hole 50 for screwing onto the thread 42 of the neck 40 of the reservoir 28. Thus, the threaded hole 50 extends helically around the axis A14 of the cosmetic product refill 14. In other words, the axis of the threaded hole 50 corresponds here to the axis A14 of the cosmetic product refill 14; and - a cap head 52 closing an upper end of the sleeve 48, oriented opposite the reservoir 28. As can be seen in particular in [Fig. 6], the cap head 52 is attached to the sleeve 48 by elastic interlocking. More precisely, ridges 54 on the cap head 52 are elastically interlocked into complementary recesses 56 on the sleeve 48. Advantageously, the cap head 52 is attached to the sleeve 48 such that these two elements are rotationally fixed around the axis A14 of the cosmetic product refill 14. To achieve this, the elastic interlocking ridges of the cap head 52 and the sleeve 48 can cooperate to limit or even prevent relative rotation of the sleeve 48 with respect to the cap head 52.In particular, the recesses 56 may be of reduced dimensions in an orthoradial direction with respect to the axis A14 of the cosmetic product refill, the recesses 56 being delimited, in the orthoradial direction, by longitudinal walls extending in radial planes with respect to the axis A14, suitable for forming stops for the ridges 54 in order to limit or even prevent a relative rotation of the sleeve 48 with respect to the cap head 52, around the axis A14 of the cosmetic product refill 14.

[0039] As illustrated in [Fig. 5], the cap head 52 is integral with a cosmetic product application element 55. The application element 55 is connected to the cap head 52 by a rod 57 such that the application element 55 is immersed in the reservoir 28 when the cap 46 is screwed onto the neck 40 of the reservoir 28. The rod 57 extends along the axis A14 of the cosmetic product refill 14. The rod 57 may be formed from the material with the cap head 52. The rod 57 may then form a recess 58 for receiving the application element 55, at its end opposite the cap head 52.

[0040] The application element 55, the stem 57 and the cap 46 thus form a device for applying the cosmetic product.

[0041] The application element 55 is, for example, a brush, in particular a mascara brush, where appropriate, a paintbrush, or any other application element accessible to a person skilled in the art.

[0042] Furthermore, the cosmetic product refill 14 includes a sleeve 60 extending around the cap 46. The sleeve 60 is generally cylindrical in shape, with a circular cross-section. The sleeve 60 is mounted to rotate freely about the axis A14 of the cosmetic product refill 14 relative to the cap 46. In other words, the sleeve 60 and the cap 46 are not rotationally fixed about the axis A14 of the cosmetic product refill 14. Thus, a rotation of the sleeve 60 relative to the reservoir 28, around the axis A14 of the cosmetic product refill 14, is not transmitted to the cap 46, particularly to the sleeve 48.

[0043] Here, the cap 46 has, at each longitudinal end or in the vicinity of each longitudinal end, a radially projecting rim 62, 64. Each rim 62, 64 of the cap 46 is received in a complementary recess 66, 68 formed at a respective opening of the sleeve 60. Thus, the sleeve 60 can be slightly axially mobile along the axis A14 of the cosmetic product refill 14, relative to the cap 46. However, the displacement of the sleeve 60 relative to the cap 46, along the axis A14, is limited, or preferably prevented, by the reception of the rims 62, 64 of the cap 46 in the complementary recesses 66, 68 of the sleeve 60.

[0044] Finally, the cap 46 has a raised feature 70 on its front surface 46f, perpendicular to the axis A14 of the cosmetic product refill 14. Here, the raised feature 70 is hollow, in the form of a recess 72 in the cap head 52. The recess 72 is generally cylindrical in shape, with its axis aligned with the axis A14 of the cosmetic product refill 14. However, the recess 72 is not circular in cross-section. According to the example shown, the recess 72 has a polygonal cross-section, in particular rectangular, preferably with rounded corners, as can be seen in particular in [Fig. 7].

[0045] As can be seen in particular in [Fig. 6] or [Fig. 7], ridges 74 extending mainly perpendicularly to the axis A14 of the cosmetic product refill 14 are formed in the housing 72, specifically on at least two opposite walls 76 of the housing 72. Here, three ridges 74 are projecting into the housing 72. Two ridges 74i are on the longer walls 76i of the housing 72, offset from the midpoint of these walls 76i. The third ridge 742 is on a shorter wall 762 of the housing 72, centered at the midpoint of this shorter wall 762.

[0046] As can be seen in [Fig. 4], in particular, a decorative ring 78 can be provided between the cover 18 and the reservoir 28 of the cosmetic product refill 14. The decorative ring 78 can, in particular, be mounted at the opening of the housing 22 in the cover 18. For example, the decorative ring 78 is received, at least partially, in a shoulder supplementing the opening of the housing 22 in the cover 18. The decorative ring 78 can also be elastically fitted onto the reservoir 28 of the cosmetic product refill 14. The decorative ring 78 can, in particular, limit the opening of the cover 18. Alternatively or additionally, the decorative ring 78 facilitates or improves the attachment of the reservoir 28 of the cosmetic product refill 14 to the cover 18.

[0047] Finally, the cap 16 of the conditioning and application device 10 is shaped to be fixed onto the cap 46 of the cosmetic product refill 14, so as to allow the cosmetic product refill 14 to be opened.

[0048] To this end, the cap 16 has a raised feature 80 that complements the raised feature 70 of the cap 46 of the cosmetic product refill 14. Thus, the raised feature 80 on the cap 16 is a projecting feature, generally cylindrical in shape, here with a substantially rectangular cross-section and rounded corners. The raised feature 80 on the cap 16 extends along the axis A16 of the cap 16, which is designed to correspond to the axis A14 of the cosmetic product refill 14 when the cap 16 is attached to the cosmetic product refill 14. Bends 82 are formed on the surface of the raised feature 80 which are designed to cooperate with the ridges 74 in the housing 72, in particular by elastic interlocking, in order to attach the cap 16 to the cap 46 of the cosmetic product refill 14.

[0049] To facilitate the manufacture of the hood 16, it is made, according to the illustrated example, in two parts, fixed together. A first part 84 is here a cylindrical shell, with axis A16 of the hood 16, inside of which a wall 86 perpendicular to the axis A16 of the hood 16 delimits two recesses 88, 90: - a first unit 88 intended to be used for refilling cosmetic products 14; and - a second housing 90, opposite the first housing 88. The relief 80 thus extends, according to the illustrated example, from the wall 86, projecting into the first housing 88. The first housing 88 is shaped to receive the cap 46 and the sleeve 60 of the cosmetic product refill 14, when the cover 16 is fixed onto the cap 46 of the cosmetic product refill 14 and, preferably, when the cosmetic product refill 14 is fixed in the base 15. In this position, the shell 84 is preferably in contact with the front surface of the base 15, around the opening of the housing 22. When the cover 16 is mounted on the reservoir 28, the sleeve 60 is interposed between the cover 16 and the cap 46. Thus, the sleeve 60 circumferentially covers the cap 46 and is circumferentially covered by the cover 16. Furthermore, according to the illustrated example, the sleeve 60 does not extend, along the direction of the extension axis A10 of the conditioning and application device 10, over substantially the entire height of the cap 46 outside the neck 40. If the cap 46, when received on the reservoir 28, protrudes from the sleeve 60 along the direction of the extension axis A10 of the conditioning and application device 10, it is by a length that does not allow the cap 46 to be grasped or, at the very least, makes grasping the cap 46 difficult for a user. For example, in this position of the cap 46 closing the reservoir 28, the cap 46 protrudes from the sleeve 60 by a height of less than 5 mm, preferably less than 2 mm, and preferably even less than 1 mm. It is noted here that the cap 46 can protrude from the socket at each of the longitudinal ends of the socket 60.In this case, the values ​​indicated above refer to the projection of the plug at each longitudinal end of the sleeve 60, and, preferably, to the sum of the projections of the plug 46 at both longitudinal ends of the sleeve 60.

[0050] The first housing 88, for example, has a height, measured along the axis A16 of the cover 16, of less than 2 cm, preferably less than 1.5 cm, and preferably even less than 1 cm. The second housing 90, for example, has a height greater than 2 cm, preferably greater than 2.5 cm, and preferably even greater than 3 cm. It should be noted here that the combined height of the first and second housings 88 and 90 corresponds approximately to the length of a gripping area for a user, allowing manipulation of the application element 55. However, it is preferable to make the first housing 88 as low as possible, particularly to limit the length of the rod 57, which can impair the precision of the manipulation of the application element 55.

[0051] The second housing 90 is closed by a disc 92 attached to the first part 84 of the hood 16. For example, the disc 92 is elastically fitted onto the first part 84 of the hood 16 or is press-fitted into the second housing 90.

[0052] As can be seen in particular from [Fig. 6], the cosmetic product refill 14 can hardly be used without the housing 12 of the cosmetic product packaging and application device. Indeed, a rotation of the sleeve 60 relative to the reservoir 28 around the axis A14 of the cosmetic product refill 14 is not transmitted to the cap 46 of the cosmetic product refill 14. Furthermore, the cap 46 of the cosmetic product refill 14 is only accessible via the upper front surface of the cap 46 – here, the cap head 52. Transmitting torque to the cap 46 is therefore particularly difficult without the cover 16 and its relief 80, which complements the relief 70 of the cap 46.

[0053] However, once the cover 16 is fixed onto the plug 46, by elastically fitting the relief 80 of the hood 16 on or in the relief 70, 72 of the cap 46, a rotation of the cap 46 relative to the reservoir 28 can be controlled by pivoting the hood 16 relative to the base 15, the reservoir 28 of the cosmetic product refill 14 being rotationally secured with the base 15 by receiving the ribs 20 in the grooves 30.

[0054] As illustrated by arrow F in [Fig. 9], the cap 46, which is integral with the cover 16, can then be screwed onto the neck 40 of the reservoir 28 (in [Fig. 9], the cover 16 is not shown). As can be seen in [Fig. 9], the cap 46, here the sleeve 48 of the cap 46, has notches 94 designed to receive the lugs 44 on the front surface of the reservoir 28. The notches 94 are here adjacent to orthoradial ramps 96. The notches 94 advantageously act as stops to prevent the cap 46 from being screwed onto the reservoir 28. The ramps 96 and the lugs 44—which here have ramps 98 that complement the ramps 96 on the cap 46—work together to allow the lugs 44 to be received, each in its respective notch 94. The notches 94 also provide resistance at the beginning of the unscrewing of the cap 46 (when the cap is rotated in the opposite direction to arrow F).In practice, the notches 94 form stops for the lugs 44, which can be lifted by forcing the cap 46. The ramps 98 on the lugs 44 cooperating with the wall of the notches 94 offer a significantly reduced resistance in the direction of unscrewing the cap 46 compared to the resistance offered by cooperation of the lugs 44 with the ramps 96 on the cap 46, in the direction of screwing F of the cap 46.

[0055] Furthermore, to remove the cosmetic product refill 14 from the case 12, it is sufficient to unclip the reservoir 28 from the casing 18 and the cover 16 from the cap 46. This can be done by applying a pull in the direction of the axis A18 of the casing 18, sufficient to cause a deformation of the elastic locking tabs 24. Thus, the pulling force to be applied is not zero, to avoid an unintentional elastic disengagement of the reservoir 28 from the casing 18, but remains limited so that it can be applied by a user with bare hands, without the need for special tools.

[0056] Fig. 10 illustrates a variant of the conditioning device 10 described above.

[0057] Thus, unlike the first example described, in this second example illustrated in [Fig. 10], the cap 46 is made in one piece. In other words, here, the sleeve 48 and the cap head 52 are made from a single piece of material.

[0058] Furthermore, in the example of [Fig. 10], the cap 46 is not attached to an application element 55 via a rod 57. Here, in fact, the packaging and application device lacks any device for dispensing or applying the cosmetic product. Here, the cap 46, in particular the cap head 52, is immersed by tiellement in the neck 40 of the reservoir to seal the reservoir tightly, a sealing gasket being provided between the neck 40 and the cap 46, in particular the cap head 52. Alternatively, the cap 46, in particular the cap head 52, does not penetrate inside the neck 40 of the reservoir 28 but rests against the neck 40 to ensure the tight closure of the reservoir 28, a sealing gasket being preferably interposed between the cap 46, in particular the cap head 52, and the neck 40.

[0059] Also, in the first example described, the reliefs 70, 72, 80 of the cap 46 and the cover 48 are cylindrical, of non-circular cross-section, and extend along an axis corresponding to the axis A14 of the thread 42 on the neck 40 of the reservoir 28 and of the tapped hole 50 on the sleeve 48 of the cap 46 of the cosmetic product refill. Alternatively, however, as illustrated in [Fig.

[10] , the ridges 70, 72, 80 can extend along different axes relative to the axis of the thread 42 and the tapped hole 50, but preferably parallel to the axis of the thread 42 and the tapped hole 50, as long as the cooperation of the ridges 70, 72, 80 makes the cap 16 and the plug 46 of the cosmetic product refill 14 fixed in rotation around the axis A14 of the thread 42 and the tapped hole 50. The ridges 70, 72, 80 can in particular extend along axes offset relative to the axis of the thread 42 and the tapped hole 50.For example, the cap 16 may have two or more ridges 70, 72, offset from the axis of the thread 42 and the tapped hole 50, cooperating with two or more ridges 80 of the plug 46. For example, the ridges 70, 72 are angularly equidistant around the axis of the thread 42 and the tapped hole 50, equidistant from the axis of the thread 42 and the tapped hole 50. In the case where the ridges 70, 72, 80 do not extend along the axis of the thread 42 and the tapped hole 50, these ridges 70, 72, 80 may be cylindrical with any cross-section, even circular. The ridges 70, 72, 80 are preferably symmetrical in pairs with respect to the axis of the thread 42 and the tapped hole 50.

[0060] The present invention is not limited to the examples just described, but is on the contrary susceptible to numerous variants accessible to those skilled in the art.

[0061] Thus, in the examples described, the relief(s) 72 on the cap 46 is / are hollow and the relief(s) 80 on the cover 16 is / are protruding. A symmetrical arrangement is, however, possible, with one or more protruding relief(s) 70 on the cap 46 and one or more complementary recessed relief(s) 80 in the cover 16. In this case, however, it appears easier to operate the cosmetic product refill 24 without first mounting it in the housing 12 of the packaging device 10. For example, it appears possible in this case to grasp the protruding relief(s) 70 of the cap, for example with pliers, to rotate the cap 46 relative to the reservoir 28 around the axis A14 of the cosmetic product refill 14.

[0062] Finally, in the first illustrated example, the conditioning device 10 is also adapted to allow the application of the cosmetic product, in that it incorporates an applicator element 55 for the cosmetic product, here provided in the cosmetic product refill 14. According to a first alternative, the applicator element 55 may not be part of the cosmetic product refill 14. According to another variant, illustrated in [Fig. 10], the packaging device 10 is without an applicator element. The packaging device 10 may then include a cosmetic product dispensing device, such as a pump or a pipette, for example. Alternatively, however, as illustrated in [Fig. 10], the packaging device 10 is without any cosmetic product application or dispensing element.
