Summary of the Invention
Problems to be Solved by the Invention
[0004] Therefore, one object of the present invention is to provide such a cover for a cosmetic device that can be easily personalized without impairing the aesthetics of the problematic cover.
[0005] In the field of beverage containers, although this field is quite different from the field of cosmetics, it is known that personalization means can be attached to the cap using screws, as described in Patent Document 1.
[0006] Patent Document 2, also within the field of beverage containers, proposes attaching a personalization element to the cap to avoid confusion between containers owned by two different people. The personalization element can take the form of a plate inserted into a corresponding slot at the top of the cap. According to another embodiment provided in that document, the personalization element takes the form of a flexible covering element spread over the cap.
[0007] These solutions do not provide a degree of aesthetic appeal suitable for the technology field of cosmetic packaging devices.
[0008] This disclosure aims to improve the situation. [Means for solving the problem]

[Figure 13]This is the same cross-sectional view as in Figure 12, illustrating the subsequent steps in removing the decorative portion from the cap in Figure 3 using the tool in Figure 10. [Modes for carrying out the invention]
[0020] In the remainder of this description, elements that are identical or have the same function share the same reference number. For the sake of brevity in this description, elements that are identical in multiple examples are not described in detail for each of these examples within the framework of the detailed description. In contrast, the description first and foremost details the differences between the various examples below.
[0021] Figure 1 illustrates an example of a cosmetic packaging device 10. Here, the packaging device 10 comprises a casing 12 in the form of a bottle 12a. The bottle 12a contains a liquid cosmetic, such as perfume or eau de toilette.
[0022] Bottle 12a extends primarily in the longitudinal direction, in this case in the direction of axis A. Hereafter, axis A will be referred to as "axis A of bottle 12a". Bottle 12a is, for example, rotationally symmetric about axis A of bottle 12a, or even perfectly rotationally symmetric about axis A of bottle 12a.
[0023] Bottle 12a here comprises a bottle body 14 that forms a neck 16. At the end of the neck 16, bottle 12a includes a ferrule 17 for securing the body 18 of the pump device 19 onto the bottle body 14, and in particular onto the neck 16 of bottle 12a. The ferrule 17 is screwed onto the neck 16 of bottle 12a, for example. The pump device 19 also includes a button 20 that is movable in translation relative to the pump body 18 in order to operate the pump device 19. A covering skirt 21 covers the ferrule 17. The function of the covering skirt 21 is basically related to aesthetics.
[0024] The packaging device 10 also includes a cover 22, which takes the form of a cap 22a.
[0025] As can be seen in the drawing, the cap 22a has a shape that is rotationally symmetric about its axis A1, which coincides with the axis A of the bottle 12a when the cap 22a is fixed on the bottle 12a.
[0026] As can be seen in Figures 2 and 3, for example, the cap 22a here comprises a hollow body 24 that defines an internal cavity 26 that opens at the upper end of the hollow body, and a decorative portion 28 that at least partially closes the internal cavity 26.
[0027] In the example shown, the hollow body 24 comprises a shroud 30 defining an internal cavity 26 and an insert 32 fixed inside the shroud 30 within the internal cavity 26.
[0028] The function of the shroud 30 is basically a covering function. The shroud 30 has an overall shape that is rotationally symmetrical about the axis A1 of the cap 22a.
[0029] The internal cavity 26 within the shroud 30 can be divided into two parts, namely - The lower portion is essentially suitable for receiving the covering skirt 21 that surrounds the ferrule 17 that secures the pump body 18 to the neck 16 of the bottle 12a. This lower portion has a substantially circular cross-section, and is, for example, cylindrical. - The upper portion forms a housing 26a that opens at the upper end of the hollow body 24, suitable for receiving 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 chamfered corners. A groove 29 is formed at each chamfered corner, extending parallel to the axis A1 of the cap 22a.
[0030] As can be seen in detail in Figures 8 and 9, the shroud 30 has a projecting relief 34 within the internal cavity 26. Here, the projecting relief 34 is substantially located at the boundary between the lower and upper portions 26a of the internal cavity 26. The projecting relief 34 extends substantially perpendicular to the direction of the axis A1 of the cap 22a. Here, the projecting relief 34 extends substantially radially with respect to the axis A1 of the cap 22a.
[0031] In particular, as can be seen in Figure 9, in the cross-section with the axis A1 of the cap 22a, the upper surface S34 of each relief 34 forms an angle a34 approximately right with the axis A1 of the cap 22a. For example, the angle a34 between the surface S34 of each relief 34 and the axis A1 of the cap 22a 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, angle a34 is equal to 75°. As noted above, angle a34 may be obtuse.
[0032] Furthermore, as can be seen particularly in Figures 3 and 4, the insert 32 has a substantially sleeve shape. In other words, the insert 32 has an overall shape that is substantially cylindrical and hollow, and has an axis A2 that coincides with the axis A1 of the cap 22a when the insert 32 is fixed inside 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 almost solid. Here, the second end 32b is a solid surface having four through-openings 35 within the solid surface. The four through-openings 35 here have the form of angled segments of the same ring, the axis of which is the axis A2 of the insert 32. The four through-openings 35 here are regularly distributed around the axis A2 of the insert 32.
[0033] The insert 32 has a flange 36 at its first end 32a. The flange 36 here forms a housing 38 suitable for covering the flange 36 of the covering skirt 21 for the ferrule 17. In one embodiment, the flange 36 can be magnetized to ensure that the cap 22a is secured to the neck 16 of the bottle 12a. Here, however, the securing of the cap 22a on the bottle 12a is achieved by friction of the insert 32 on the covering skirt 21 for the ferrule 17. To adjust the friction between the insert 32 and the covering skirt 21 for the ferrule 17, a longitudinally flat region 46 may be provided on the inner surface of the insert 32.
[0034] Alternatively, the cap 22a can be secured to the bottle 12a by screwing or snap fitting, in particular by snap fitting, and in particular by clipping.
[0035] Furthermore, the insert 32 has snap-fit reliefs 40 formed on its substantially cylindrical surface. Here, the snap-fit reliefs 40 take the form of beads positioned longitudinally on or near the second end 32b of the insert 32. The insert 32 has four such snap-fit reliefs 40, as illustrated. However, the insert 32 may have more or fewer snap-fit reliefs 40, in particular at least one snap-fit relief 40, or at least two snap-fit reliefs 40, preferably at least three snap-fit reliefs 40. The snap-fit reliefs 40 are preferably regularly distributed at angles around the axis A2 of the insert 32.
[0036] As can be seen in particular in Figure 4, each snap-fit relief 40 here has a lower surface S40 oriented toward the first end of the insert 32, and this surface forms an angle a40 with the axis A2 of the insert 32, which is neither flat nor right. For example, in the cross-section of the insert 32 with the axis A2 of the insert 32 illustrated in Figure 4, the angle a40 between the lower surface S40 of the bead 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 approximately equal to 45°. As noted above, the angle a40 is preferably acute.
[0037] Each surface S40 also has a height h40 measured in the direction of axis A2 of the insert 32.
[0038] The insert 32 also has a surface 41 connecting the upper end of surface S40 to the second longitudinal end 32b of the insert 32, which is cylindrical with a circular or even slightly tapered cross-section, so that the diameter of surface 41 decreases from the upper end of surface S40 toward the second longitudinal end 32b of the insert 32. In a longitudinal cross-section having axis A2 of the insert 32, the angle between surface 41 and 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 surface 41 is axis A2 of the insert 32. The upper end of surface 41 may be rounded when viewed in cross-sectional view.
[0039] The insert 32 also forms protrusions 42 on its radially outer surface. An example insert 32 has four such protrusions 42. The insert 32 may have more or fewer protrusions 42, in particular at least one or two protrusions 42, preferably at least three protrusions 42. The protrusions 42 are preferably regularly distributed at angles around the axis A1 of the cap 22a.
[0040] Each protrusion 42 projects radially outward from the cylindrical portion of the insert 32. Each protrusion 42 has a shape that extends mainly circumferentially over the cylindrical portion of the insert 32.
[0041] In particular, as can be seen in Figure 4, each protrusion 42 here has a triangular cross-section, and its lower surface S42 forms approximately a right angle with the axis A2 of the insert 32. For example, in the cross-section of the insert 32 with 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 surface S42 is preferably approximately equal to the angle a34 of the upper surface S34 of each relief 34 of the shroud 30, where angle a42 is equal to 75°. As noted above, angle a42 may be obtuse.
[0042] Finally, here, the insert 32 has longitudinal ribs 44 on its cylindrical portion that extend longitudinally only on a portion of the radially outer surface of the insert 32. More specifically, the insert 32 has pairs of such longitudinal ribs 44. In detail, in the exemplary example, the insert 32 has four pairs of longitudinal ribs 44, which are regularly distributed on the radially outer surface of the cylindrical portion of the insert 32.
[0043] It should be noted that the opening 35 and the bead 40 are aligned along the direction of the axis A2 of the insert 32. Similarly, the protrusion 42 and the pair of longitudinal ribs 44 are also aligned along the direction of the axis A2 of the insert 32. According to the particular embodiment shown in the drawings, the opening 35, the bead 40, the protrusion 42, and the pair of longitudinal ribs 44 are aligned along the direction of the axis A2 of the insert 32.
[0044] In particular, as can be seen in Figure 8, the shroud 30 is secured to the insert 32 by a protruding relief 34 of the shroud 30, which snaps into a protrusion 42 of the insert 34. To achieve this, the insert 32 is inserted into the shroud 30, and this insertion is guided by a longitudinal rib 44 of the insert 32, which is received into a complementary groove 47 in the shroud 30. The position of the insert 32 is thus indexed relative to the shroud 30. In other words, the insert 32 can only be inserted into the shroud 30 at a finite and limited number of relative angular positions. Here, there are four such relative angular positions. The insert 32 is then pushed into the shroud 30 until the protruding relief 34 of the shroud 30 snaps into the protrusion 42 of the insert 32.
[0045] It should be noted here that the snap fit of the insert 32 in the shroud 30 is permanent because the surfaces S34 of the protruding relief 34 and S42 of the protrusion 42 are nearly perpendicular a34, a42, working together to ensure the fixation of the insert 32 in the shroud 30 and the direction of insertion of the insert 32 into the shroud 30, which is parallel to the axis A1 of the cap 22a. In other words, it is extremely difficult, or even impossible, to remove the insert 32 from the shroud 30 without damaging one of the two parts, in particular the protruding relief 34 of the shroud 30 and / or the protrusion 42 of the insert 32, etc. Such disassembly of the insert 32 from the shroud 30 is increasingly difficult due to their relatively high rigidity, as well as due to the shapes of the protruding relief 34 and the protrusion 42.
[0046] Securing the insert 32 into the shroud 30 by snap fitting appears to be durable, easy to achieve, and, above all, easy to implement, without requiring any additional parts.
[0047] Naturally, the insert 32 can be secured inside the shroud 30 by means other than snap fitting. Specifically, the insert 32 can be secured inside the shroud 30 with adhesive. Additionally, or alternatively, the insert 32 can also be forcibly inserted into the shroud 30 and held there by friction.
[0048] The decorative part 28 is described in more detail below.
[0049] As can be seen in Figures 2 and 3, the decorative portion 28 has a surface F28 facing outward from the cap 22a, which is fitted with the decoration 48.
[0050] The decorations 48 of the decorative part 28 are as follows: -Regarding the colors, aside from the 24 colors of the hollow body, the most noteworthy are the colors other than the 30 colors of the shroud. - Patterns, especially patterns that mimic specific materials. - At least one disc made of a specific material, or that mimics the appearance of a specific material, - Commercial brands, especially logos, -A selection can be made from recessed or protruding reliefs.
[0051] As can be seen particularly in Figure 3, the exemplary decorative portion 28 consists of a decorative plate 50, a forming surface F28 with decoration 48, and a support plate 52. It is preferable to implement the decorative portion 28 as at least two separate parts, because this allows for greater variation in the decorative plate 50, the function of which these plates is purely aesthetic. In particular, the decorative plate can be made from a wider variety of materials in this case. The support plate 52 then secures the decorative portion 28 to the insert 32, as will be described in more detail below.
[0052] Here, the decorative plate 50 is flat.
[0053] The decorative plate 50 is fixed to the support plate 52. For example, the decorative plate 50 is fixed to the support plate with adhesive. However, other means of fixing the decorative plate 50 to the support plate 52 are also possible. For example, the decorative plate 50 can be securely mounted within the frame formed by the support plate 52.
[0054] The support plate 52 is illustrated in particular in Figures 5 and 6.
[0055] As can be seen in these drawings, the support plate 52 extends essentially perpendicular to axis A3, which is the centerline of the support plate 52, and is intended to coincide with axis A1 of the cap 22a when the decorative portion 28 is fixed inside the cap 22a.
[0056] The support plate 52 has a substantially flat surface to which the decorative plate 50 is intended to be fixed.
[0057] The support plate 52 also includes a tab 54 whose free end has the shape of a hook 56. For example, in a cross-section of the support plate 52 having an axis A3 perpendicular to the support plate 52, the angle a56 between the upper surface 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 surface S56 is greater than or equal to the lower surface S40 of the bead 40 of the insert 32. This is equal to the angle a40 between the axis A2 of the insert 32. Here, for example, angle a56 is approximately equal to 45°. As noted above, angle a56 is preferably acute.
[0058] The support plate 52 also includes a tongue-shaped portion 57. Here, the tongue-shaped portion 57 extends at a specific angle relative to the support plate 52. The tongue-shaped portion 57 extends along the principal direction of the extension parallel to axis A3 perpendicular to the support plate 52. Here, the tongue-shaped portion 57 is substantially a parallelepiped.
[0059] The support plate 52 further comprises through holes 58. Here, there are four through holes 58. Each through hole 58 has an overall angled sector shape of the same ring. The through holes 58 are regularly distributed at angles 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, among other things, allow for the release 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 the molding of the tab 54 described below. With respect to the excess adhesive between the support plate 52 and the decorative plate 50, at least one of these plates 50, 52, in particular the support plate 52, may be provided with a recess capable of receiving at least a portion of the excess adhesive.
[0060] The flanges protrude from the support plate 52 from the radially inner edge of the through hole 58 on the side opposite to the side intended to receive the decorative plate 50, and each flange thus forms a ridge 60. The ridges 60 have a height h60 measured, for example, from the surface of the support plate 52 from which they protrude, in the direction of axis A3 perpendicular to the support plate 52, which is substantially equal to the height of the opening 35 in the insert 32. Thus, the ridges 60 are suitable to be received within the opening 35 in order to partially close them without extending beyond the opening 35.
[0061] As can be seen in particular in Figures 8 and 9, the decorative portion 28 is secured to the insert 32 by snap-fitting the tabs 54 of the support plate 52 with the first snap-fit relief 34 in the form of a bead of the insert 32. The tongue-shaped portion 57 of the support plate 52 is received within the complementary housing 26a of the shroud 30 and can guide the insertion of the decorative portion 28 along a straight path in the internal cavity 26 defined by the shroud 30.
[0062] Once the decorative portion 28 is fixed to the insert 32, the protrusion 60 of the support plate 52 extends inside the opening 35 of the insert 32. However, the protrusion 60 does not protrude beyond the opening 35 of the insert 32 in the direction of the first end 32a of the insert 32.
[0063] Furthermore, as can be seen particularly in Figures 8 and 9, once the decorative portion 28 is fixed to the insert 32, the portion is completely housed within the internal cavity 26 of the shroud 30. In other words, the surface forming surface F28 of the decorative portion 28 is preferably coplanar with the upper end of the shroud 30, or even slightly recessed relative to the upper end. This thus prevents removal, or attempts to remove, of the decorative portion by grasping a portion of the edge of the decorative portion 28 protruding from the shroud 30 in the direction of the axis A1 of the cap 22a.
[0064] Furthermore, the decorative portion 28 fixed to the insert 32 extends into the internal cavity 26 of the shroud 30 with a reduced gap j. For example, the gap j between the decorative portion 28 and the wall defining the internal cavity 26 of the shroud 30 at the upper end of the cap 22a is, for example, less than or equal to 1 mm, preferably less than or equal to 0.5 mm, and more preferably less than or equal to 0.2 mm. In an attempt to remove the decorative portion 28 from the cap 22a, it is thus difficult, or even impossible, to insert a rigid element into the gap between the decorative portion 28 and the shroud 30 to achieve leverage.
[0065] However, due to the angles a40, a56 formed by the surfaces S40, S56 of the bead 40 and hook 56, which are slightly inclined relative to the direction of the axis A1 of the cap 22a, the snap fitting of the decorative portion 28 on the protrusion 42 can be disassembled without damaging the components of the cap 22a, and in particular without damaging the decorative portion 28, the shroud 30, or the insert 32. This disassembly is facilitated by the relative flexibility of the tab 54. Thus, the bead 40 and tab 54 are molded to allow, for example, the disassembly of the decorative portion 28 from the hollow body 24 by pushing one of the decorative portion 28 and the hollow body 24 toward the other in the direction of the axis A1 of the cap 22a. In this case, a force applied parallel to the axis A1 of the cap 22a causes elastic deformation of the tab 54, and the surface S56 of the hook 56 follows the inclined path formed by the surface S40 of the bead 40 until the snap-fitting surfaces S40, S56 no longer face each other at all. The pushing force required for this disassembly is, for example, greater than or equal to 10N, preferably greater than or equal to 15N and / or less than or equal to 50N, preferably less than or equal to 30N. This reduces the chance of damaging the component parts of the cap 22a. The pushing force in one particular example is approximately equal to 20N.
[0066] The movement to remove the decorative portion 28 can be continued from a position where surfaces S40 and S56 are no longer facing each other at all, and the hook 56 follows the tapering surface 41 at the top of the insert 32, note that this is because the tab 54 tends to return to a position substantially parallel to the axis A2 of the insert 32.
[0067] However, due to the structure of the cap 22a, accessing the decorative part 28 to apply force, such as pressing, is relatively difficult. Specifically, it is impossible to apply such force to the decorative part 28 by inserting a finger into the cap 22a. This reduces the risk of unintended disassembly of the decorative part 28.
[0068] In order to remove the decorative part 28 from the hollow body 24, it is hereby proposed that, in detail, when the user wishes to replace the decorative part 28, the tool 100 illustrated in Figures 10 and 11 be used. Figure 11 illustrates an assembly 200 formed by such a tool 100 and the corresponding cap 22a.
[0069] The fixture 100 includes a relief 102 suitable for receiving the cap 22a, more specifically, into the insert 32, within the hollow body 24 of the cap 22a, so as to contact the decorative portion 28, as illustrated. Here, the relief 102 takes the form of a cylindrical rod 104 projecting from the base 106 in the direction of axis A4, which is intended to coincide with axis A1 of the cap 22a when the cap 22a is received on the fixture 100. The cylindrical rod 104 is hollow, for example, to facilitate manufacturing by molding. The cylindrical rod 104 has a tab 108 at its free end, which is molded so as to be received into the opening 35 in the insert 32 and to contact the ridge 60 of the support plate 52 of the decorative portion 28 when the cap 22a is received on the fixture 100. To enable such receiving, the fixture 100 forms a housing 110 around the cylindrical rod 104, molded to receive the cap 22a. The housing 110 is externally bounded by a wall 112. The wall 112 may, in particular, be capable of guiding the relative movement of the cap 22a with respect to the fixture 100. Here, two of the opposing walls 112 have recesses 114 at their tops to facilitate the removal of the hollow body 24 when the decorative portion 28 is removed, as described below. Alternatively, a single wall 112 may have such recesses 114, or three or more walls 112 may have such recesses 114. In detail, each wall 112 may have such recesses 114.
[0070] The base 106 of the fixture 100 also has a pedestal 107 at the base of the relief 102. The cross section of the pedestal 107 is complementary to the housing 38 at the end 32a of the insert 32. However, the pedestal 107 has a height h107 measured along the axis A4 of the fixture, which is greater than or equal to the height of the housing 38 at the end 32a of the insert 32 measured along the direction of axis A2.
[0071] The utensil 100 is made of, for example, plastic. Preferably, the utensil is made of a material that has a lower hardness than the material from which the cap 22a is made, and / or a flexible material to avoid damage to the cap 22a when the utensil 100 is used. The edges of the utensil 100 are also preferably rounded or chamfered.
[0072] Using device 100 is easy.
[0073] First, as illustrated in Figure 12, the cap 22a is placed in a predetermined location on the fixture 100, so that the tab 108 of the fixture 100 comes into contact with the protrusion 60 of the support plate 52. The tab 108 of the fixture 100 can then extend at least partially through the opening 35 in the insert 32.
[0074] The positioning of the cap 22a on the fixture 100 can be facilitated by the walls 112 defining the housing 110, which can guide the cap 22a on the cylindrical rod 104. The housing 110 here is rotationally symmetric about axis A1 and has a cross-section complementary to the cross-section of the upper part of the shroud 30. It should be noted here that the positioning is also facilitated by the fact that the cap 22a is rotationally symmetric about its axis A1, and therefore the four positions allow the cap 22a to be received on the fixture 100, more specifically, within the housing 110, all leading to the same configuration. Conversely, a cap 28 that is perfectly rotationally symmetric does not seem very favorable for the easy positioning of the cap 22a on the fixture 100. It is certainly possible that the tab 108 of the fixture 100 is not in direct contact with the protrusion 60 of the support plate 52, and in this case, relative rotation of the cap 22a with respect to the fixture 100 is essential, given the complete lack of visual cues to facilitate such positioning through relative rotation.
[0075] In the latter case in particular, the fixture 100 may be provided with an angled indexing mechanism for the cap 22a, which ensures that the cap 22a is precisely positioned on the fixture 100, thereby allowing the force pushing the cap 22a toward the fixture 100 to be removed, as well as the decorative part 28.
[0076] Next, the cap 22a is further inserted into the housing 110 of the fixture 100. In other words, the cap 28 is pushed in the direction of the axis A1 of the cap 22a, toward the fixture 100. This pushing action is guided by the wall 112 of the housing 110. This pushing action results in the tab 108 being pressed against the ridge 60 of the hole 58 in the support plate 52. The relatively large inclination of the surfaces S40, S56 of the reliefs 40, 56 allows the decorative part 28 to be mounted onto the insert 32, and / or due to the elasticity of these reliefs, in particular the elasticity of the tab 54 that carries the hook 56, it is now possible to "release the snap fit" of the reliefs 56, 40 and remove the decorative part 28 from the cap 22a without damaging the decorative part 28, the shroud 30, or the insert 32.
[0077] The height h108 of the tab 108 added to the height h60 of the ridge 60 may, in such cases, be at least greater than or equal to the height h40 of the bead 40. Preferably, the height h108 of the tab 108 added to the height h60 of the ridge 60 may, in such cases, be greater than or equal to the height h40 of the bead 40 when added to the height h41 of the surface 41 connecting the upper end of surface S40 to the second longitudinal end 32b of the insert 32. In other words, the height h108 of the tab 108 added to the height h60 of the ridge 60 may, in such cases, be greater than or equal to the distance measured in the direction of the axis A2 of the insert between the lower (or free) end of surface S56 of the hook 56 and the second end 32b of the insert 32.
[0078] Preferably, the pressing action on the cap 28 is possible over a path c whose length, as measured in the direction of axis A4 of the instrument 100, is at least greater than or equal to the height h40 of the bead 40. Preferably, the path c has a length greater than or equal to the height S41 of the surface 41 connecting the upper end of the bead 40 plus 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 measured along the direction of axis A2 of the insert 32 between the lower (or free) end of surface S56 of the hook 56 and the second end 32b of the insert 32.
[0079] Path c is slightly less than or equal to the height h108 of tab 108, so that the bottom of insert 32 does not come into contact with the upper end of the cylindrical rod 104 before insert 32 comes into contact with the base 107.
[0080] Once removed, the decorative part 28 can be stored, in particular for later reassembly on the cap 22a of the bottle 12a, or, in some cases, on another cover 22 suitable for a different casing 12. A new decorative part 28 can then be placed inside the cap 22a and replace the removed decorative part 28. This placement is performed by snap fitting, in principle, without the need for the use of any tools.
[0081] This disclosure is not limited to the embodiments described above merely as examples, but encompasses all variations that are foreseeable to those skilled in the art within the scope of the required protection. In particular, the various examples described above can be combined, provided that their teachings do not contradict each other.
[0082] For example, in the example above, the packaging device for cosmetics is a perfume bottle with a built-in pump. However, bottles may not always have such a pump.
[0083] The attachment of decorative elements as described above can also be performed on the caps of packaging devices for lipsticks, particularly for the use of cosmetics for the lips. The cap then displays such decorative elements. The cap can be fixed to a lipstick body that includes a lipstick mechanism.
[0084] Caps may also be implemented as described above in devices for packaging and dispensing liquid cosmetics, particularly mascara or lip gloss. In this case, the cap may be integrated with an applicator component for the liquid cosmetic. For example, a rod connects the cap to the applicator component for the cosmetic. The rod can be fixed to an insert in the cap, or may be made of the same material as the insert. In this case, the free end of the cylindrical rod of the device 100 advantageously has a hole that allows the rod and applicator component to pass through when the cap is placed on the device.
[0085] Furthermore, in the example shown, the fixture 100 does not cooperate with the snap-fit relief of the decorative part, but rather pushes the decorative part. Naturally, it is impossible to access the snap-fit relief of the decorative part from the inside of the insert. These snap-fit reliefs are therefore not visible to the user, which contributes to the aesthetic appearance of the cap 22a. However, alternatively, the snap-fit relief of the decorative part may be fixed to the insert so that it can be accessed from the inside of the insert. For example, the snap-fit relief of the decorative part may take the form of a tab that crosses an opening in the insert and can be fixed to each edge of one of these openings. In this case, the tab of the fixture 100 can cooperate directly with these snap-fit reliefs. This reduces the force applied to the snap-fit tab to directly push the decorative part, causing the snap-fit tab to deform elastically while following the complementary snap-fit relief, thereby disassembling the decorative part. The risk of damaging one of the cap's components during the disassembly of the decorative part is therefore further reduced.
[0086] In another variant, the snap-fit relief of the decorative part works in conjunction with the complementary snap-fit formed by the cap. [Explanation of Symbols]
