Description

technical field

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

[0002] In the cosmetics industry, a packaging device typically consists of a container and a lid to close it. The lid may have an external metal casing. Such a metal casing is particularly appreciated by users. Applications FR 2 565 559 A1 and EP 4 014 786 A1 disclose such packaging devices.

[0003] However, the hood usually has a plastic insert. The insert may contain magnets to cooperate with other magnets attached to the casing, to close the packaging device.

[0004] However, this design of the packaging devices, particularly the packaging device cover, presents an environmental drawback. Indeed, to recycle the cover, it is necessary to disassemble the plastic insert from the rest of the metal cover. Consequently, many covers are not recycled at all.

[0005] Furthermore, all-metal covers are known. However, these are generally screwed or press-fitted onto the case they close.

[0006] Users consider such methods of closing the container via the lid to be impractical. They prefer a snap-fit ​​closure, the characteristic "click" of which allows the user to ensure that the packaging device is properly closed. Summary

[0007] This disclosure improves the situation.

[0008] The present disclosure proposes a conditioning device according to claim 1.

[0009] Advantageously, it is possible to create a cosmetic product packaging device incorporating at least one elastic grip element made of metal. This metal elastic grip element can be formed by the cap, a cap insert, the casing, or a flange attached to the casing. In all cases, this allows for the recycling of a larger portion of the packaging device compared to cases where the element bearing this elastic grip element is made of another material, particularly plastic.

Description of the implementation methods

[0012] In the following description, identical elements or elements with identical functions are designated by the same reference symbol. For the sake of brevity, elements that are identical in multiple examples are not described in detail within the detailed description of each individual example. Instead, the description below primarily details the differences between the various examples.

[0013] There figure 1 illustrates a detail of an initial device 10 packaging of a cosmetic product. The first packaging device 10 includes a case 12, here in the form of a bottle 12. The bottle 12 contains a liquid cosmetic product, for example a perfume or eau de toilette.

[0014] The bottle 12 extends mainly along one direction, in this case the direction of an axis X. In what follows, we call the axis X, "the axisX of the bottle 12 The bottle 12 is, for example, symmetrical by rotation around the axis X of the bottle 12, or even, as here, with rotational symmetry around the axis X of the bottle 12.

[0015] The bottle 12 includes here a bottle body 14, forming a neck 16. At the end of the collar 16, the bottle 12 includes a fret 18, fixed to the bottle body 14, in this case on the neck 16 of the bottle body 14. The fret 18 extends the pass here 16 of the bottle 12.

[0016] The fret 18 is here with rotational symmetry around the axis X of the bottle 12. As is particularly evident on the figures 3 And 4 the fret 18 consists of two portions 18 1 , 18 2 adjacent, each generally cylindrical in shape, and a portion 18 3 substantially annular, in this case generally disc-shaped. The two cylindrical portions 18 1 , 18 2 are superimposed here in the direction of the axis X of the bottle 12. The annular portion 18 3 defines the free end of the fret 18, away from the bottle 12. The annular portion 18 3 of the fret 18 defines here an opening 20 of the bottle 12, in fluid communication with the inside of the bottle body 14. The cylindrical portion 18 1 the upper portion is adjacent to the annular portion 18 3 the cylindrical portion 18 1 upper and annular portions 18 3 forming a shoulder. The cylindrical portion 18 2 lower fret 18, facing the bottle 12, is fixed to the neck 16 of the bottle body 14.Here, the cylindrical portion 18 2 lower fret 18 has an outer diameter greater than the outer diameter of the cylindrical portion 18 1 upper fret 18, which is approximately equal to the outer diameter of the annular portion 18 3 According to the illustrated example, the cylindrical portion 18 2 lower fret 18 has an inner diameter equal to the inner diameter of the cylindrical portion 18 1 upper fret 18, but greater than the inner diameter of the annular section 18 3 .

[0017] The cylindrical portion 18 1 upper fret 18 present, in the vicinity of the opening 20, a first elastic interlocking relief 22, here in the form of a groove 22. The groove 22 is circular here. According to the illustrated example, the groove 22is continuous here all around the cylindrical portion 18 1 The upper groove. 22 is here contained in a plane perpendicular to the axis X of the bottle 12.

[0018] The fret 18, in particular the cylindrical portion 18 1 upper portion and, where applicable, the annular portion 18 3 may have a thickness greater than or equal to 0.3 mm and / or less than or equal to 5 mm. The fret 18 is thus rigid, in particular rigid enough that it is difficult or even impossible to deform the fret 18 with bare hands.

[0019] To close the opening 20 and, thus, close the case 12, the conditioning device 10 includes a hood 24. Here, the hood takes the form of a cap. 24. The cork 24 is more clearly visible on the figures 2 And 4 .

[0020] As can be seen in the figures, the cap 24 has a shape with rotational symmetry around an axis X 1 the cork 24, corresponding to the axis X of the bottle 12 when the cap 24 is attached to the bottle 12.

[0021] As can be seen in these figures, the cap 24 includes a headdress 26, defining an internal cavity 28, and an insert 30, fixed in the internal cavity 28 of the headdress 26. The headdress 26 It thus has a socket shape with a circular cross-section, open at only one end.

[0022] The headdress 26 includes here a first part 26 1 approximately cylindrical with axis the axis X 1 the cork 24, one end of which is blocked by a second part 26 2 of the headdress 26. Part Two 26 2 It is roughly disc-shaped here. The second part 26 2 here it rests upon and is fixed to an annular surface 32 internal part of the first part of the headgear 26 1 Part Two 26 2 of the headdress 26 can notably be glued or welded onto the first part 26 1 of the headdress 26. Other means of attaching the second part 26 2 of the headdress 26 on the first part 26 1 of the headdress 26 are also accessible to the expert.

[0023] The insert 30 also has a socket shape in the illustrated example, with the axis X 1 the cork 24. A first extremity 30 1 longitudinal of the insert 30 is thus full, while a second end 30 5 longitudinal, opposite to the first end 30 1 longitudinal of the insert 30,is openwork. In the vicinity of the first end 30 1 longitudinal, the insert 30 forms a first portion 30 2 cylindrical extending longitudinally along the axis X 1 the cork 26, up to a shoulder 30 3 The insert 30 includes here a second portion 30 4 roughly cylindrical extending from the shoulder 30 3 , up to the second end 30 5 longitudinal of the insert 30. The second portion 30 4 The cylindrical section here has internal and external diameters greater than the internal and external diameters of the first portion. 30 2 cylindrical, respectively. The inner diameter of the second portion 30 4 cylindrical insert 30 is here approximately equal to the outer diameter of the upper portion 18 1 cylindrical fret 18.

[0024] In the illustrated example, the second portion 30 4 cylindrical insert 30 is slightly flared near the second end 30 5 longitudinal of the insert 30.

[0025] The insert 30 has a thickness that can, for example, be greater than or equal to 0.1 mm and / or less than or equal to 5 mm, or even less than 1 mm. Thus, the insert 30 is also rigid, so the insert is difficult to deform by hand, or even impossible to deform. 30 with bare hands.

[0026] Here on the second portion 30 4 cylindrical, the insert 30 comprises a plurality of pairs of slots 34. Here, the pairs of slots 34 are regularly distributed angularly around the axis X 1 the cork 24, on the surface of the second portion 30 4 cylindrical. The slots 34are all identical here. By slot, we mean an opening, here radial in the insert 30. Thus, each slot 34 it passes through the thickness of the body in which it is formed, here the thickness of the insert 30. Each slot 34 can be achieved by removing material from the body in which it is created, in this case from the insert 30. Alternatively, however, each slot 34 can be achieved by cutting out the body in which it is created, here in the insert 30, substantially without any material being removed from this body, or from the insert respectively 30. In all cases, each slot 34 separates, along a radial and / or orthoradial direction, two edges of material of the body in which it is made, here two edges of the insert 30. Each slot 34 extends longitudinally here, parallel to the axis X 1 the cork 24. As seen on the figure 2in particular, each slot 34 is not through-hole, in that each slot 34 extends between two longitudinal ends formed in the insert 30, more specifically in the second portion 30 4 cylindrical insert 30 in the example illustrated on the figure 2 Each slot 34 passes through the thickness of the insert 30, in particular the second portion 30 4 cylindrical insert 30. The insert 30 for example, it includes at least two pairs of slots 34, preferably at least three pairs of slots 34, Ideally, at least four pairs of slots. 34. The slots 34 allow the insert material to become significantly more flexible 30 extending between the two slits 34.

[0027] Between two slits 34 of a pair of slots 34, the second portion 30 4 cylindrical insert 30 forms a tongue 35 elastic interlocking system, featuring a convex shape 36 (or boss) oriented radially towards the inside of the insert 30. Each bulge 36 is achieved here by embossing.

[0028] As illustrated on the figure 2 each tab 35 material came from each of its ends, along with the rest of the insert 30, particularly with the rest of the second portion 30 4 cylindrical insert 30. Each tab 35 is separated from the rest of the insert 30, along the lateral sides of the tongue 35, extending parallel to the axis X 1 through the slots in the cork 34 each extending along one lateral side of the tongue 35.

[0029] Each tab 35 can extend, with the exception of the bulge 36if applicable, in the cylindrical extension of the rest of the insert 30 (that is, the insert) 30 lacking tabs 3 5) or more generally of the body in which the slits are formed 34 delimiting the tabs 35. Alternatively, however, each tab 35 does not extend in the cylindrical continuation of the rest of the insert 30.

[0030] Each tab 35 - and therefore each slot 34 - has a length, measured here along the direction of the axis X 1 the cork 24, greater than or equal to 2 mm, preferably greater than or equal to 4 mm, and less than or equal to 15 mm, preferably less than or equal to 10 mm.

[0031] Each bulge 36 extends longitudinally in a direction perpendicular to the axis X 1 the cork 24, here along an orthoradial direction relative to the axis X 1 the cork 24. Each bulge 36 maybe across the entire width of the tongue 35 corresponding. Alternatively, however, each bulge 36 is on only part of the width of the tongue 35. In particular, each bulge 36 maybe on at least half the width of the tongue 35, preferably over at least three-quarters of the width of the tongue 35.

[0032] Each bulge 36 can be formed approximately in the middle of the tongue's height 35 corresponding. The deformation of the tongue 35 is indeed significantly greater in the middle of its height than at its longitudinal ends, in particular.

[0033] The bulge 36 presents a height, measured along the direction of the axis X 1 the cork 24, which is less than the height of the slits 34,measured along the same axis direction X 1 the cork 24. For example, the height of the bulge 36 is greater than or equal to 0.1 mm, preferably greater than or equal to 0.5 mm, and / or less than or equal to 3 mm, preferably less than or equal to 2 mm. The width of the bulge 36, measured along a circumferential or orthoradial direction, may be greater than or equal to 1 mm, preferably greater than or equal to 2 mm, and / or less than or equal to 20 mm, preferably less than or equal to 10 mm. The distance between the apex of the bulge 36 and the cylindrical casing of the insert 34, measured along a radial direction relative to the axis X 1 the cork 24, can be less than 2 mm, preferably less than 1 mm. The tab 35 It thus offers good flexibility, while maintaining satisfactory mechanical resistance.

[0034] Each tab 35 equipped with a bulge36, extending between two slits 34, thus forms a second elastic interlocking relief 37, on the insert 30. Preferably, every second elastic interlocking relief 37 consists of such a tongue 35 extending between two slits 34 and equipped with a bulge 36. Also remarkably, such a second elastic interlocking relief 37 is formed by a metal part, in this case by the insert 30 made of metal. In other words, it is thus possible to create a second elastic interlocking relief. 37 exhibiting sufficient elasticity to deform in order to allow the cap to be fixed 24 on the bottle 12 by elastic interlocking, even if this second elastic interlocking relief 37 is formed by a metal part, in this case the insert 30 which is here made of metal.

[0035] As seen on the figure 4 in particular, the insert 30 is sandwiched longitudinally, between the first part 26 1 of the headdress 26 and the second part 26 2 of the headdress 26, in the vicinity of the first extremity 30 1 of the insert 30. In particular, the second cylindrical portion 30 4 of the insert 30 is at its limit, at the level of the second longitudinal end 30 5 against an annular surface 38 formed by a shoulder inside the first part 26 1 of the headdress 26. The first longitudinal end 30 1 of the insert 30 can also be butted against and / or fixed to the second part 26 2 of the headdress 26.

[0036] Each among the fret 18, the headdress 26 and the insert 30It can be made of metal, particularly an aluminum alloy, more specifically ZAMAC, an alloy of zinc, aluminum, magnesium, and copper where zinc is the predominant component. Advantageously, the cap 26 and the insert 30 are made of the same material. Alternatively, or in addition, the fret 18 and the insert 30 are made of the same material. It appears particularly advantageous that the fret 18, the headdress 26 and the insert 30 all three be made of the same material.

[0037] To close the bottle 12, we're pushing the envelope 24 along the direction of the axis X of the bottle 12, towards the bottle 12. The tabs 35 between two slits 34 neighbors, bearing the bombé 36, are then elastically deformed by contact with the fret 18, particularly with the cylindrical portion 18 1 upper fret 18. More specifically, each bulge 36 is flattened radially and / or locally pushes back the tabs 35 between two slits 34 neighbors. When the bulges 36 arrive opposite the groove 22, each bulge 36 and / or each tab 35 It expands elastically. Each bulge 36 is then received in the groove 22. This reception of the bombs 36 in the groove 22 may be accompanied by a characteristic "click" indicating that the cap is secured by an elastic snap-fit ​​(or "clip-on") 24 on the fret 18 of the bottle 12. This type of fastening is particularly appreciated by users because it ensures that the cap is securely attached. 24 on the bottle 12. This elastic interlocking system thus utilizes the tabs 35 elastic interlocking fittings with a convex shape36, which extend between two adjacent slits 34.

[0038] THE Figures 5 And 6 illustrate a second example of a conditioning device 100 of cosmetic product.

[0039] According to this second example, the bottle 12 is equipped with a pump 40. To do this, here, the pass 16 of the bottle body 14 features a thread 42 extending to the vicinity of the opening 44 of the pass 16 of the bottle body 14. Here, the fret 18 allows the pump body to be fixed 40 on the pass 16 of the bottle body 14.

[0040] The first elastic interlocking relief 22 here it takes the form of a circular rib extending all around the neck 16. The first elastic interlocking relief 22 is arranged in such a way that the thread 42extends between the first elastic interlocking relief 22 and the opening 44 of the pass 16, This is to allow the pump to be fixed. 40 on the pass 16, and, on top of the pump 40, the cork 24 on the bottle 12.

[0041] As illustrated on the right half of the figure 6 Here, the cork 24 is elastically fitted onto the bottle 12, especially on the pass 16 of the bottle 12, by cooperation of the first elastic interlocking relief 22 on the bottle 12, with secondary elastic interlocking reliefs 37 on the insert 30, as described in the first example.

[0042] It should be noted here that the bottle 12 can be made of any material accessible to a skilled craftsman. The bottle 12 may, in particular, not be made of metal, so that the cap's attachment 24on the bottle 12 This is then achieved by elastic interlocking of reliefs, only one of which is made of metal; here, the second elastic interlocking relief. 37.

[0043] THE figures 7 And 8 illustrate a third example of a conditioning device 200 of cosmetic product. This third example of a packaging device 200 East a priori particularly suitable for packaging cosmetic products in solid form, including powder, paste or gel.

[0044] This third example of a cosmetic product packaging device 200 thus includes a case 12 which is wider and longer than it is tall. The case 12 can notably define compartments, each compartment being filled with a different cosmetic product.

[0045] In this case, the hood 24 takes the form of a lid.

[0046] Here, the insert 30, metallic, essentially has a crown shape 30c, on which the tabs are made 35, the slits 34 and the bulges 36 second elastic interlocking reliefs 37 as described previously in relation to the first two examples. The second set of elastic interlocking reliefs 37 are, for example, on each side of the crown 30c of the insert 30, in the vicinity of each corner of the crown 30c Two opposite sides of the crown 30c are joined here by an arch 30a formed by the insert 30. The hoop 30a also forms reinforcing tabs 30I. These reinforcing tabs 30I can, in particular, strengthen the attachment of the insert 30 in the internal cavity 28 delimited by the lid 24, for example when the reinforcing tabs 30Iare glued to the lid 24.

[0047] To cooperate with the bombings 36 second elastic interlocking reliefs 37 of the insert 30 and allow for a flexible fit of the lid 24 on the case 12, the edge of the case 12 here forms a first elastic interlocking relief 22 protruding. For example, the edge of the case 12 is folded in such a way as to form a rib 22 extending around the entire circumference of the case 12.

[0048] Alternatively, the lid 24 can be mounted to rotate relative to the case 12, on one side of the case 12, by means of at least one hinge. In this case, the insert 30 of the lid 24 may exhibit fewer secondary elastic interlocking reliefs 37 in the form of sets of tabs 35 extending between two slits 34neighboring and each equipped with a bulge 36 extending between the two slits 34 neighboring. For example, the insert 30 may include a single such second elastic interlocking relief 37, on one side of the lid 12, opposite the hinge side.

[0049] There figure 9 illustrates a fourth example of a cosmetic product packaging device 300. This refers more specifically to a device for packaging a lipstick or a lip care product.

[0050] In this case, the casing 12 receives a lipstick mechanism 46, receiving a lipstick tube (not shown). Such a lipstick mechanism is known to 46 allows you to move the lipstick tube along its length. X of the conditioning device 300, by rotating a ring 48 of the case12.

[0051] Here again, the cork 24 of the conditioning device 300 and the lipstick body 14 may be similar to what has been described with regard to the figures 1 to 4 , so that the cap 24 is fixed to the body of the lipstick 14 by elastic interlocking of first and second elastic interlocking reliefs 22, 37 as described previously.

[0052] There Figure 10 illustrates a fifth example of a conditioning device 400 in which the cork 24 is attached to an applicator element 50 A cosmetic product, for example, a brush. The cosmetic product is then more specifically suited for application to eyelashes, eyebrows, or lips. The cosmetic product could be, for example, mascara or lip gloss.

[0053] Here, the applicator element 50 is attached to a rod52, itself attached to the insert 30. The stem 52 is long enough to allow the applicator element 50 to be immersed in the cosmetic product, when the cap 24 is attached to the bottle 12. In this closed position of the conditioning device 400, the stem 42 passes through a spin-drying device 54 allowing the removal of excess cosmetic product picked up by the applicator element 50, when the latter is removed from the bottle 12.

[0054] In this fifth example of a conditioning device 400 also, the cap 24 can be attached to the bottle 12 by elastic interlocking of first and second elastic interlocking reliefs 22, 37 as described previously.

[0055] This disclosure is not limited to the examples described above, which are merely illustrative, but encompasses all the variations that a person skilled in the art might consider in the context of the protection sought. In particular, the various examples described above may be combined as long as their lessons are not contradictory.

[0056] Furthermore, the positions of the first and second elastic interlocking reliefs 22, 37 are susceptible to numerous variations accessible to those skilled in the art. figures 11 to 13 illustrate with examples.

[0057] Thus, on the figure 11 the first elastic interlocking reliefs 22 are on a first frontal face 56 of the case 12, perpendicular to the longitudinal direction X. The first front face 56 is here formed by an annular surface of a shoulder formed on the outer face of the casing 12,particularly the pass 16 of the case 12. The second elastic interlocking reliefs 37 are on a second front face 58 hood 24, perpendicular to the longitudinal direction X. Here, the second front face 58 corresponds to the annular rim of a cavity 60 in the hood 24. In this case, it is interesting that the external cylindrical surface 62 of the case 12 and the internal cylindrical surface 64 hood 24 Each has a thread that complements the other. This is how the hood is attached. 24 on the case 12 by screwing it until the first and second elastic interlocking ridges fit together 22, 37.

[0058] In the case of the example of the figure 11 each clip tab 35 and the slits 34which define it, can then extend substantially in a plane normal to the axis X 1 hood 24. Specifically, each clip tab 35 and the slits 34 which delimit it extend longitudinally in a radial or orthoradial direction relative to the axis X 1 hood 24. To do this, the slots 34 and the clip tabs 35 corresponding can be formed on an annular portion of an insert fixed inside a cap delimiting the cavity 60, the annular portion forming the second frontal face 58 hood 24. Each bulge can then extend equally in a plane normal to the axis X 1 Specifically, each bulge extends longitudinally in a direction perpendicular to the direction of the slots defining the clip tab on which the bulge is formed. The distance between the apex of the bulge36 and the annular base surface, in which the slots delimiting the clip tabs are made, measured along the axis direction X 1 the cork 24, can be less than 2 mm, preferably less than 1 mm.

[0059] Alternatively, the clip tabs can be formed on the first front surface 56 of the case 12. In particular, the clip tabs can be formed by a ring fixed to the housing 12, comprising an annular surface forming the first frontal surface 56. The orientations of the tongues, slots and bulges can be identical to those indicated previously, taking the axis as a reference. X of the case 12 instead of the axis X 1 hood 24.

[0060] Following the example of the figure 12 the first elastic interlocking reliefs 22are formed on an annular edge 66 forming the longitudinal end of the case 12, the annular edge 66 being perpendicular to the direction of the axis X of the case 12. The annular edge 66 extends around an opening of the housing in the casing 12. The annular edge 66 is sometimes called drinking, especially when the case 12 is a bottle.

[0061] In the case of the figure 12 the second elastic interlocking reliefs 37 can then be at the bottom 68 hood 24 socket-shaped.

[0062] In the case of the figure 12 also, the hood 24 can be screwed onto the case 12 up to the elastic interlocking of the first and second elastic interlocking reliefs 22, 37.

[0063] In the case of the example of the figure 12Clipping tabs can be made in much the same way as just described for the example of the figure 11 , in particular on an insert fixed inside the hood 24 or on a fret fixed to the case 12. In particular, the orientation of the clip tabs, the slots delimiting these clip tabs, and the bulges on these clip tabs may be identical to those indicated in the description of the example of the figure 11 .

[0064] Following the example of the figure 13 the first and second elastic interlocking reliefs 22, 37 are on cylindrical surfaces 62, 64, respectively in the vicinity of the drinking hole 66 and from the bottom 68. In this case, the hood 24 can be fixed by elastic interlocking of the first and second elastic interlocking ridges 22, 37 by moving the hood 24 compared to the case 12along the direction of the axis X of the conditioning device.

[0065] Here, the second elastic interlocking reliefs can be made as described opposite the figure 2 In particular, the orientations of the clip tabs, slots, and bulges can be identical to those indicated in the description of this embodiment. For example, the position of the second elastic interlocking ridges could be moved along the axis. X 1 hood 24, on the insert 30, compared to the position illustrated in the figure 2 .

[0066] Alternatively, the clip tabs could form the first clip ridges. 22.In this case, the clip tabs, slots and corresponding bulges can be made near an opening in the housing 12, particularly on a cylindrical surface whose axis corresponds to the axis X of the case 12. The orientations of the clip tabs, slots, and corresponding bulges can then be identical to those described opposite the example of the figure 2 taking the axis as the reference axis X of the case 12, instead of the axis X 1 of the hood 24.

[0067] Also, as mentioned above and unlike the illustrated examples, in which each time the second elastic interlocking reliefs 37 carried by the hood 24 take the form of a tongue 35 metallic space delimited by two slots 34 and wearing a bulge 36, Alternatively, the first elastic interlocking reliefs 22can take such a form. In this case, it is interesting that the first reliefs of elastic interlocking 22 These components are formed by a metal housing, particularly a metal housing body, or by a metal collar fixed to such a housing body, especially if the housing body is not metallic. This method effectively creates elastic interlocking reliefs on metal parts where it is normally very difficult to achieve such elastic interlocking reliefs.

[0068] Furthermore, in the examples described, tabs are used 35 elastic interlocking system with convex shapes 36, particularly formed by embossing. However, other forms of the tabs 35 Elastic interlocking systems can be considered.

[0069] Finally, the relief(s) with which these elastic interlocking tabs cooperate can take different forms, including one among a groove, a rib and at least one lug, preferably a plurality of lugs.
