Description

TECHNICAL FIELD

[0001] The present disclosure relates to the field of cosmetic packaging devices. BACKGROUND

[0002] Users are particularly sensitive to the aesthetics of cosmetic packaging devices. In any case, users are always seeking personalized products, in particular the personalizable aesthetics of the packaging devices. Users also wish to be able to adapt the personalization of their cosmetic containers to their needs over the lifetime of the cosmetic packaging device. Thus, users wish to have the possibility of removing one personalization element to replace it with another element without having to purchase a new cosmetic packaging device.

[0003] It is therefore an object of the present invention to provide an easily personalizable cover for a cosmetic device without compromising the aesthetics of the cover in question.

[0004] In the field of beverage containers, which is apparently far removed from the field of cosmetic products, it is known to attach a personalization member on the lid by means of a screw, as described in the application US 2010 / 0187196 Al.

[0005] The application US 2012 / 0138563 Al, which is also within the field of beverage containers, proposes attaching a personalization element to the lid in order to avoid confusion between containers of two different owners. The personalization element can take the form of a plate inserted into a corresponding slot at the top of the lid. According to a further embodiment provided herein, the personalization element takes the form of a flexible cover element which is deployed onto the lid.

[0064] In the rest of the description, identical or identically functioning elements bear the same reference signs. For the sake of conciseness of the description, identical elements in several instances are not described in detail within the framework of the detailed description for each of these instances. On the contrary, the following description primarily details the differences between the various instances.

[0065] Figure 1 An example of a cosmetic packaging device 10 is shown. Here, the packaging device 10 comprises a housing 12 in the form of a bottle 12a. The bottle 12a contains a liquid cosmetic, for example a perfume or eau de toilette.

[0066] The bottle 12a extends mainly in a longitudinal direction, which in this case is the direction of the axis A. In what follows, the axis A is referred to as the "axis A of the bottle 12a". The bottle 12a is for example rotationally symmetric around the axis A of the bottle 12a, or even perfectly rotationally symmetric around the axis A of the bottle 12a.

[0067] Here, the bottle 12a comprises a bottle body 14, forming a neck 16. At the end of the neck 16, the bottle 12a comprises a sleeve 17 for fixing a body 18 of a pump device 19 on the bottle body 14, in particular on the neck 16 of the bottle 12a. The sleeve 17 is for example screwed onto the neck 16 of the bottle 12a. The pump device 19 further comprises a push button 20 that is translationally mobile with respect to the pump body 18 in order to actuate the pump device 19. A covering skirt 21 covers the sleeve 17. The function of the covering skirt 21 is essentially aesthetic.

[0068] The packaging device 10 further comprises a covering piece 22. Here, the covering piece 22 takes the form of a cap 22a.

[0069] As can be seen in the figures, the cap 22a has a shape that is rotationally symmetric around an axis A1 of the cap 22a, which corresponds to the axis A of the bottle 12a when the cap 22a is fixed on the bottle 12a.

[0070] As can be seen in the figures, the cap 22a has a shape that is rotationally symmetric around an axis A1 of the cap 22a, which corresponds to the axis A of the bottle 12a when the cap 22a is fixed on the bottle 12a. Figure 2 and 3 ​​​As can be seen in particular in

[0071] In the illustrated example, the hollow body 24 comprises a shroud 30 defining the inner cavity 26, and an insert 32 fixed inside the shroud 30 in the inner cavity 26.

[0072] The shroud 30 has essentially a covering function. The shroud 30 has a general shape which is rotationally symmetrical around the axis Al of the cap 22a.

[0073] The inner cavity 26 in the shroud 30 can be divided into two parts:

[0074] - a lower part adapted to receive substantially the covering skirt 21 around the sleeve 17 fixing the pump body 18 to the neck 16 of the bottle 12a. This lower part is for example cylindrical, with a generally circular cross-section;

[0075] - an upper part forming a housing 26a open at the upper end of the hollow body 24, adapted to receive the upper end of the button 20 of the pump device 19 and the upper end of the insert 32. Here, the housing 26a has a square cross-section with bevelled corners. At each bevelled corner, a groove 29 is formed extending parallel to the axis Al of the cap 22a.

[0076] As can be seen in particular in Figure 8 and 9 As can be seen more particularly in

[0077] As can be seen in particular in Figure 9 In particular in a cross-section comprising the axis Al of the cap 22a, the upper surface S34 of each relief 34 forms a substantially right angle a34 with the axis Al of the cap 22a. For example, the angle a34 between the surface S34 of each relief 34 and the axis Al of the cap is greater than or equal to 60°, preferably greater than or equal to 70°, and / or less than or equal to 120°, preferably less than or equal to 110°. Here, the angle a34 is equal to 75°. As indicated above, the angle a34 can be obtuse.

[0078] In addition, as can be seen in particular in Figure 3 and 4As can be seen in the figures, the insert 32 has the general shape of a sleeve. In other words, the insert 32 has a generally cylindrical and hollow general shape, with an axis A2 corresponding to the axis Al of the cap 22a when the insert 32 is fixed in the cap 22a. The first end 32a of the insert 32 is empty or hollow. The second end 32b, opposite the first end 32a, is mostly solid. Here, the second end 32b is a solid face, which includes four through openings 35 in the solid face. Here, the four openings 35 have the form of a same annular angular sector, with the axis being the axis A2 of the insert 32. Here, the four openings 35 are regularly distributed around the axis A2 of the insert 32.

[0079] The insert 32 has a flange 36 at its first end 32a. Here, the flange 36 forms a shell 38 adapted to cover the flange 39 of the covering skirt 21 for the sleeve 17. In one embodiment, the flange 36 can be magnetized to ensure the fixing of the cap 22a on the neck 16 of the bottle 12a. However, here, the fixing of the cap 22a on the bottle 12a is achieved by friction of the insert 32 on the covering skirt 21 for the sleeve 17. A longitudinal flat area 46 can be provided on the inner face of the insert 32 to adjust the friction between the insert 32 and the covering skirt 21 for the sleeve 17.

[0080] Alternatively, the cap 22a can be fixed to the bottle 12a by screwing or snapping, in particular by snapping, especially clipping.

[0081] Furthermore, the insert 32 forms snapping reliefs 40 on the generally cylindrical surface of the insert 32. Here, the snapping reliefs 40 take the form of a protuberance arranged longitudinally at or near the second end 32b of the insert 32. As shown, the insert 32 comprises four such snapping reliefs 40. However, the insert 32 can comprise more or less snapping reliefs 40, in particular at least one snapping relief 40 or at least two snapping reliefs 40, preferably at least three snapping reliefs 40. The snapping reliefs 40 are preferably regularly distributed angularly around the axis A2 of the insert 32.

[0082] As Figure 4 As can be seen in particular in the figures, here, the snapping reliefs 40 have a lower face S40 oriented towards the first end of the insert 32, forming an angle a40 with the axis A2 of the insert 32 which is neither a flat angle nor a straight angle. For example, in the cross-section of the insert 32 shown in the figures, the angle a40 between the lower face S40 of the protuberance 40 and the axis A2 is greater than or equal to 30°, preferably greater than or equal to 40°, and / or less than or equal to 60°, preferably less than or equal to 50°. Here, for example, the angle a40 is substantially equal to 45°. As indicated above, the angle a40 is preferably an acute angle. Figure 4 As can be seen in particular in the figures, here, the snapping reliefs 40 have a lower face S40 oriented towards the first end of the insert 32, forming an angle a40 with the axis A2 of the insert 32 which is neither a flat angle nor a straight angle. For example, in the cross-section of the insert 32 shown in the figures, the angle a40 between the lower face S40 of the protuberance 40 and the axis A2 is greater than or equal to 30°, preferably greater than or equal to 40°, and / or less than or equal to 60°, preferably less than or equal to 50°. Here, for example, the angle a40 is substantially equal to 45°. As indicated above, the angle a40 is preferably an acute angle.

[0083] Each surface S40 also has a height h40 measured in the direction of the axis A2 of the insert 32.

[0084] The insert 32 also has a surface 41 connecting the upper end of the surface S40 to the second longitudinal end 32b of the insert 32, which is cylindrical, has a circular or even slightly tapered cross-section, such that the diameter of the surface 41 decreases from the upper end of the surface S40 towards the second longitudinal end 32b of the insert 32. In a longitudinal section including the axis A2 of the insert 32, the angle between the surface 41 and the axis A2 is thus for example greater than 0°, and / or less than or equal to 10°, preferably less than or equal to 5°. Alternatively, the axis of the surface 41 is the axis A2 of the insert 32. The upper end of the surface 41 can be rounded when viewed in cross-section.

[0085] The insert 32 also forms lugs 42 on the radially outer face. As illustrated, the insert 32 comprises four such lugs 42. However, the insert 32 can comprise more or fewer lugs 42, in particular at least one or two lugs 42, preferably at least three lugs 42. The lugs 42 are preferably regularly distributed angularly around the axis A1 of the cap 22a.

[0086] Each lug 42 projects radially outwards from the cylindrical portion of the insert 32. Each lug 42 has a shape extending mainly circumferentially above the cylindrical portion of the insert 32.

[0087] As can be seen in particular in Figure 4 here, each lug 42 has a triangular cross-section, the lower surface S42 of which forms a substantially right angle with the axis A2 of the insert 32. For example, in a section of the insert 32 including the axis A2 of the insert 32, the angle a42 between the lower surface S42 and the axis A2 of the insert 32 is greater than or equal to 60°, preferably greater than or equal to 70°, and / or less than or equal to 120°, preferably less than or equal to 110°. The angle a42 of the surface S42 is preferably substantially equal to the angle a34 of the upper surface S34 of each of the flaps 34 of the shroud 30. Here, the angle a42 is equal to 75°. As indicated above, the angle a42 can be obtuse.

[0088] Finally, here, the insert 32 has longitudinal ribs 44 on the cylindrical portion thereof, which extend longitudinally over only a portion of the radially outer surface of the insert 32. More precisely, the insert 32 has pairs of such longitudinal ribs 44. In particular, in the example illustrated, the insert 32 has four pairs of longitudinal ribs 44 regularly distributed over the radially outer surface of the cylindrical portion of the insert 32.

[0089] Notably, the opening 35 and the tab 40 are aligned along the direction of the axis A2 of the insert 32. Similarly, here, the lug 42 and the pair of longitudinal ribs 44 are aligned along the direction of the axis A2 of the insert 32. According to the particular embodiment illustrated in the figures, the opening 35, the tab 40, the lug 42 and the pair of longitudinal ribs 44 are aligned along the direction of the axis A2 of the insert 32.

[0090] As can be seen in particular in Figure 8 Here, the shroud 30 is fixed to the insert 32 by snapping the relief 34 of the shroud 30 with the lug 42 of the insert 32. To this end, the insert 32 is inserted into the shroud 30, this insertion being guided by the longitudinal ribs 44 of the insert 32 received in the complementary grooves 47 in the shroud 30. The position of the insert 32 is thus indicated with respect to the shroud 30. In other words, the insert 32 can only be inserted into a limited and restricted number of relative angular positions in the shroud 30. Here, the number of these relative angular positions is four. The insert 32 is then pushed into the shroud 30 until the relief 34 of the shroud 30 snaps with the lug 42 of the insert 32.

[0091] It is noted that here, due to the substantially right angle a34, a42 between the surfaces S34, S42 of the relief 34 and the lug 42 cooperating to ensure the fixing of the insert 32 in the shroud 30 and the direction of the insertion of the insert 32 into the shroud 30 which is parallel to the axis Al of the lid 22a, the snapping of the insert 32 in the shroud 30 is permanent. In other words, it is difficult, even impossible, to remove the insert 32 from the shroud 30 without damaging one of these two parts, in particular the relief 34 of the shroud 30 and / or the lug 42 of the insert 32. The relatively high rigidity of the relief 34 and the lug 42, if only due to their shape, makes it even more difficult to disassemble the insert 32 from the shroud 30.

[0092] The snapping of the insert 32 in the shroud 30 appears to be durable and in particular easy to implement, without additional parts.

[0093] Of course, the insert 32 can be fixed in the shroud 30 by means other than snapping. In particular, the insert 32 can be glued into the shroud 30. Additionally or alternatively, the insert 32 can be inserted into the shroud 30 with force and held there by means of friction.

[0094] In the following, the decorative part 28 is described in more detail.

[0095] As can be seen in particular in Figure 2 and 3 The decorative part 28 comprises a face F28 facing outwards from the lid 22a, which is provided with a decoration 48.

[0096] The decoration 48 of the decorative part 28 can in particular be chosen among the following:

[0097] - a color, in particular a color other than the color of the hollow body 24, in particular of the shroud 30,

[0098] - a pattern, in particular imitating a material,

[0099] - at least one disc made of a material or imitating the appearance of a material,

[0100] - a commercial brand, in particular a logo,

[0101] - a concave or convex relief.

[0102] As can be seen in particular in Figure 3 , the illustrated decorative part 28 is composed of a decorative plate 50 forming a face F28 provided with the decoration 48 and of a support plate 52. It is preferred to implement the decorative part 28 as at least two separate pieces because this allows a greater variety of decorative plates 50, the function of which is only aesthetic. In particular, in this case, the decorative plate can be made of a greater variety of materials. The support plate 52 then fixes the decorative part 28 to the insert 32, as will be described in more detail below.

[0103] Here, the decorative plate 50 is flat.

[0104] The decorative plate 50 is fixed to the support plate 52. For example, the decorative plate 50 is glued to the support plate 52. However, other means of fixing the decorative plate 50 to the support plate 52 are possible. For example, the decorative plate 50 can be tightly mounted within a frame formed by the support plate 52.

[0105] The support plate 52 is in particular illustrated in Figure 5 and 6 .

[0106] As can be seen in these figures, the support plate 52 extends substantially perpendicularly to the axis A3, which is the center line of the support plate 52, which is intended to correspond to the axis Al of the lid 22a when the decorative part 28 is fixed in the lid 22a.

[0107] The support plate 52 has a substantially flat face on which the decorative plate 50 is intended to be fixed.

[0108] The support plate 52 further comprises a tab 54, the free end of which has the shape of a hook 56. For example, in a cross section of the support plate 52 comprising an axis A3 perpendicular to the support plate 52, an angle a56 between an upper face S56 of the hook 56 and the axis A3 perpendicular to the support plate 52 is greater than or equal to 30°, preferably greater than or equal to 40°, and / or less than or equal to 60°, preferably less than or equal to 50°. Preferably, the angle a56 of the upper face S56 is equal to an angle a40 between a lower face S40 of the protrusion 40 of the insert 32 and the axis A2 of the insert 32. Here, for example, the angle a56 is substantially equal to 45°. As indicated above, the angle a56 is preferably an acute angle.

[0109] The support plate 52 further comprises a tongue 57. Here, the tongue 57 extends at an angle with respect to the support plate 52. The tongue 57 extends along a main extension direction parallel to an axis A3 perpendicular to the support plate 52. Here, the tongue 57 is substantially parallelepiped.

[0110] The support plate 52 further comprises through holes 58. Here, there are four through holes 58. Each through hole 58 has the general shape of a same annular angular sector. The through holes 58 are regularly distributed at an angle around an axis A3 perpendicular to the support plate 52. The through holes 58 are equidistant from the center of the support plate 52. The through holes 58 can notably allow the evacuation of excess adhesive from between the support plate 52 and the decorative plate 50, and / or facilitate the molding of the support plate 52, in particular of the tab 54 described below. With regard to excess glue between the support plate 52 and the decorative plate 50, at least one of these plates 50, 52, in particular the support plate 52, can comprise notches allowing to receive at least some of said excess glue.

[0111] Flanges protrude from the support plate 52 from the radially inner edge of the through holes 58 on the face of the support plate 52 opposite the face of the support plate 52 intended to receive the decorative plate 50, each flange thus forming a ridge 60. The ridges 60 have a height h60, measured for example in a direction perpendicular to the axis A3 of the support plate 52, from the surface of the support plate 52 from which they protrude, substantially equal to the height of the opening 35 in the insert 32. Thus, the ridges 60 are adapted to be received in the opening 35 to partially close the opening, without extending beyond the opening 35.

[0112] As can be seen in particular in Figs. 2 and 3, the decorative part 28 is fixed to the insert 32 by snapping the hook 56 of the tab 54 of the support plate 52 with the first snap relief 34 in the form of a protrusion of the insert 32. The tongue 57 of the support plate 52 can be received in the complementary housing 29 of the shroud 30 to guide the insertion of the decorative part 28 along a rectilinear path within the inner cavity 26 defined by the shroud 30. Figure 8 and 9 As can be seen in particular in Figs. 2 and 3, the decorative part 28 is fixed to the insert 32 by snapping the hook 56 of the tab 54 of the support plate 52 with the first snap relief 34 in the form of a protrusion of the insert 32. The tongue 57 of the support plate 52 can be received in the complementary housing 29 of the shroud 30 to guide the insertion of the decorative part 28 along a rectilinear path within the inner cavity 26 defined by the shroud 30.

[0113] Once the decorative part 28 is fixed to the insert 32, the ridge 60 of the support plate 52 extends within the opening 35 of the insert 32. However, the ridge 60 does not protrude beyond the opening 35 of the insert 32 in the direction of the first end 32a of the insert 32.

[0114] Moreover, as can be seen in particular in Figure 8 and 9 Once the decorative part 28 is fixed to the insert 32, said part is entirely received within the inner cavity 26 of the shroud 30. In other words, the surface forming the face F28 of the decorative part 28 is preferably flush with the upper end of the shroud 30 or even slightly recessed with respect to said upper end. This thus prevents the removal or attempted removal of the decorative part by gripping a portion of the edge of the decorative part 28 protruding from the shroud 30 in the direction of the axis Al of the lid 22a.

[0115] Moreover, the decorative part 28, fixed to the insert 32, extends into the inner cavity 26 of the shroud 30 with a reduced gap j. By way of example, at the upper end of the lid 22a, the gap j between the decorative part 28 and the wall delimiting the inner cavity 26 of the shroud 30 is for example less than or equal to 1 mm, preferably less than or equal to 0.5 mm, more preferentially less than or equal to 0.2 mm. It is thus difficult, if not impossible, to insert a rigid element into the gap between the decorative part 28 and the shroud 30 to achieve a lever action in order to attempt to remove the decorative part 28 from the lid 22a.

[0116] However, due to the relatively slight inclination of the angle a40, a56 formed by the surfaces S40, S56 of the tab 40 and of the hook 56 with respect to the direction of the axis Al of the lid 22a, the fastening of the demountable decorative part 28 on the lug 42 can be undone without damaging the components of the lid 22a, in particular without damaging the decorative part 28, the shroud 30 or the insert 42. The relative flexibility of the tab 54 contributes to this dismounting. Thus, the tab 40 and the tab 54 are for example shaped to allow the dismounting of the decorative part 28 from the hollow body 24 by pushing one of the decorative part 28 and of the hollow body 24 with respect to the other in the direction of the axis Al of the lid 22a. In this case, the force applied parallel to the axis Al of the lid 22a causes the elastic deformation of the tab 54, the surface S56 of the hook 56 following the slope formed by the surface S40 of the tab 40 until the fastening surfaces S40, S56 are no longer facing each other at all. The pushing force necessary for this dismounting is for example greater than or equal to 10 N, preferably greater than or equal to 15 N, and / or less than or equal to 50 N, preferably less than or equal to 30 N. This reduces the probability of damaging the components of the lid 22a. According to one particular example, said pushing force is substantially equal to 20 N.

[0117] It is noted that the movement to remove the decorative part 28 can continue from a position in which the surfaces S40, S56 are no longer facing each other at all, the hook 56 following the tapered surface 41 at the top of the insert 32, as the tab 54 tends to return to a position substantially parallel to the axis A2 of the insert 32.

[0118] However, due to the configuration of the cap 22a, it is relatively difficult to access the decorative part 28 to exert this pushing force. In particular, it is not possible to exert this force on the decorative part 28 by inserting a finger into the cap 22a. This reduces the risk of unintended disassembly of the decorative part 28.

[0119] Here, especially when the user wishes to replace the decorative part 28, it is proposed to use the tool 100 shown in Figure 10 and 11 to remove the decorative part 28 from the hollow body 24. Figure 11 An assembly 200 formed by this tool 100 and the associated cap 22a is shown.

[0120] The tool 100 as shown comprises a relief 102 adapted to be received in the hollow body 24 of the cap 22a, in particular in the insert 32, to come into contact with the decorative part 28. Here, the relief 102 takes the form of a cylindrical rod 104 protruding from a base 106 in a direction of an axis A4 intended to correspond to the axis Al of the cap 22a when the cap 22a is received on the tool 100. The cylindrical rod 104 is for example hollow to facilitate production by molding. The cylindrical rod 104 has a tab 108 at its free end shaped to be received in the opening 35 in the insert 32 and to contact the ridge 60 of the support plate 52 of the decorative part 28 when the cap 22a is received on the tool 100. To allow this reception, the tool 100 forms a housing 110 shaped to receive the cap 22a around the cylindrical rod 104. The housing 110 is delimited externally by a wall 112. In particular, the wall 112 can allow to guide the relative movement of the cap 22a with respect to the tool 100. Here, two of the relative walls 112 have a notch 114 at their top which facilitates the removal of the hollow body 24 when the decorative part 28 has been removed, as will be described below. Alternatively, a single wall 112 can have this notch 114, or more than two walls 112. In particular, each wall 112 can have this notch 114.

[0121] The base 106 of the tool 100 also has a seat 107 at the bottom of the relief 102. The seat 107 has a cross section complementary to the housing 38 at the end 32a of the insert 32. However, the seat 107 has a height h107 measured along the axis A4 of the tool which is greater than or equal to the height of the housing 38 at the end 32a of the insert 32 measured in the direction of the axis A2.

[0122] Tool 100 is made of, for example, plastic. Preferably, the tool is made of a material with a lower hardness than the material used to make the cap 28 and / or a softer material, to prevent damage to the cap 28 when using tool 100. It is also possible that the edges of tool 100 are rounded or beveled.

[0123] Easy-to-use tools 100%.

[0124] First, such as Figure 12 As shown, the cap 22a is positioned in the appropriate location on the tool 100 such that the lug 108 of the tool 100 contacts the ridge 60 of the support plate 52. The lug 108 of the tool 100 may then extend at least partially through the opening 35 in the insert 32.

[0125] The walls 112 defining the housing 110 facilitate the positioning of the cap 22a on the tool 100, making it possible to guide the cap 22a on the cylindrical rod 104. Here, the housing 110 thus has a cross-section that is rotationally symmetrical about axis A1, complementary to the cross-section of the upper portion of the shield 30. It should be noted that the cap 22a is also rotationally symmetrical about its axis A1, such that all four positions on the tool 100 (specifically within the housing 110) result in the same configuration. Conversely, a fully rotationally symmetrical cap 28 would seem less advantageous for easily positioning the cap 22a on the tool 100. In fact, it is possible that the lugs 108 of the tool 100 do not directly face the ridge 60 of the support plate 52, and therefore a relative rotation of the cap 22a relative to the tool 100 is necessary, without any visual cues to aid in achieving this positioning through relative rotation.

[0126] In particular, in the latter case, a means of indicating the angle of the cover 22a in the tool 100 can be provided, thereby making it possible to ensure that the cover 22a is correctly placed on the tool 100, such that the thrust on the cover 22a toward the tool 100 actually enables the removal of the decorative part 28.

[0127] Second, the cover 22a is further inserted into the housing 110 of the tool 100. In other words, the cover 28 is pushed in the direction of the tool 100, in the direction of the axis A1 of the cover 22a. This push is guided by the wall 112 of the housing 110. This push causes the lug 108 to advance against the ridge 60 of the hole 58 of the support plate 52. Due to the relatively large inclination of the surfaces S40, S56 of the undulations 40, 56 that allow the decorative part 28 to attach to the insert 32 and / or due to the elasticity of these undulations (especially the lug 54 that carries the hook 56), it is possible to “disengage” the undulations 56, 40 and remove the decorative part 28 from the cover 22a without damaging the decorative part 28, the cover 30, or the insert 32.

[0128] The height h108 of the tab 108 plus the height h60 of the ridge 60, when these are present, can be at least greater than or equal to the height h40 of the convexity 40. Preferably, the height h108 of the tab 108 plus the height h60 of the ridge 60, when these are present, is preferably greater than or equal to the height h40 of the convexity 40 plus the height h41 of the surface 41 connecting the upper end of the surface S40 to the second longitudinal end 32b of the insert 32. In other words, the height h108 of the tab 108 plus the height h60 of the ridge 60, when these are present, is preferably greater than or equal to the distance between the lower (or free) end of the surface S56 of the hook 56 and the second end 32b of the insert 32, measured in the direction of the axis A2 of the insert.

[0129] Preferably, a pushing force on the cap 28 is possible on a path c, the length of which, measured in the direction of the axis A4 of the tool 100, is at least greater than or equal to the height h40 of the convexity 40. Preferably, the length of the path c is greater than or equal to the height h40 of the convexity 40 plus the height h41 of the surface 41 connecting the upper end of the surface S40 to the second longitudinal end 32b of the insert 32. In other words, the path c is preferably greater than or equal to the distance between the lower (or free) end of the surface S56 of the hook 56 and the second end 32b of the insert 32, measured in the direction of the axis A2 of the insert.

[0130] The path c is slightly less than or equal to the height h108 of the tab 108, in order to prevent the bottom of the insert 32 from abutting the upper end of the cylindrical rod 104 before the insert abuts the base 107.

[0131] The decorative part 28 can thus be kept when it is removed, notably for later reassembly on the cap 22a of the bottle 12a or possibly on another cover 22 adapted to another housing 12. A new decorative part 28 can then be placed in the cap 22a, replacing the decorative part 28 that was removed. This placement is carried out by snapping, in principle without the need to use any tools.

[0132] The present disclosure is not limited to the embodiments described above by way of example only, but encompasses all variants that can be conceived by a person skilled in the art within the framework sought to be protected. In particular, the various examples described above can be combined, provided that their technical teachings are not contradictory.

[0133] For example, in the examples described above, the packaging device for cosmetics is a perfume bottle fitted with a pump. However, the bottle can be devoid of such a pump.

[0134] The attachment of the decorative part just described can also be implemented on the lid of the packaging device, for the application of lip makeup products, in particular lipsticks. The lid thus has this decorative part. The lid can be fixed to the body of the lipstick comprising the lipstick mechanism.

[0135] It is also possible to implement the lid as described above in a device for packaging and applying a liquid makeup product, in particular mascara or lip gloss. In this case, the lid can be integral with the applicator assembly for the liquid makeup product. For example, a stem connects the lid to the applicator assembly for the makeup product. The stem can be fixed to or made of the same material as the insert in the lid. In this case, the free end of the cylindrical stem of the tool 100 advantageously has a hole allowing the stem and the applicator assembly to pass therethrough when the lid is placed on the tool.

[0136] Furthermore, in the example illustrated, the tool 100 does not cooperate with the snap catches of the decorative part, but rather pushes on the decorative part. Indeed, the snap catches of the decorative part are not accessible from the inside of the insert. These snap catches are thus not visible to the user, which contributes to achieving an aesthetic appearance of the lid 22a. However, alternatively, the snap catches of the decorative part are fixed to the insert, to be accessible from the inside of the insert. For example, the snap catches of the decorative part can take the form of tabs that pass through openings in the insert, and can each be fixed to the rim of one of these openings. In this case, the tabs of the tool 100 can directly cooperate with these snap catches. This reduces the force to be applied to the decorative part to disassemble it by pushing directly on the snap tabs, which will then elastically deform while following the complementary snap catches. The risk of damaging one of the parts of the lid during disassembly of the decorative part is further reduced.

[0137] Also, according to another variant, the snap catches of the decorative part cooperate with complementary snaps formed by the lid.
