This at least one connection zone is adapted to cooperate with another closure element, such as the ring and the cap, by elastic deformation to removably join the two closure elements together. A closure assembly for a cosmetic product container is also shown.

Description

technical field

[0001] The invention relates to the field of containers for cosmetic products, and more particularly to closures for such containers. Previous technique

[0002] Millions of cosmetic products (perfumes, lipsticks, mascaras, etc.) of all kinds are sold every second worldwide each year. The containers are traditionally made entirely or partially of plastic, and represent a significant source of waste that can pollute the environment.

[0003] Plastic is used not only for its low cost but also for its elastic properties. It is common practice to attach the cap to the cosmetic container using an elastic interlocking mechanism, also known as snap-fit. This involves temporarily deforming one piece of plastic locally to insert it into another, thus attaching, for example, a cap to its container.

[0004] In the perfume industry, the ring may be metallic, but the stopper, which features the elastic protrusion for a secure fit, is typically made of plastic. While metal stoppers do exist, they are traditionally stamped and seal the perfume bottle simply by friction against the ring, without any resistance or click, giving the user the impression of a lower-quality product.

[0005] Document EP3736227A1 shows an example of cosmetic product closure. Summary

[0006] A closure element for cosmetic product containers is proposed, the closure element being intended to be assembled with another closure element to form a closure assembly consisting of a cap and a ring, the closure element comprising: a metallic wall having at least one metallic and elastically deformable connection zone, said at least one connection zone being partially detached from the rest of the wall, and said at least one connection zone being adapted to cooperate with the other closure element by elastic deformation to removably assemble the two closure elements together, where said at least one connection zone is fully formed to the wall.

[0007] Thanks to the elastically deformable connection zone (i.e., elastic deformation), an elastic fit can be achieved between two closing elements, i.e., between a ring and a cover.

[0008] Not only does the metal construction avoid potentially polluting plastic, but it also gives the container a luxurious look by producing a deep, satisfying closing sound.

[0009] The features described in the following paragraphs may optionally be implemented. They may be implemented independently or in combination with each other: The connection zone includes a tab. The tab includes a protrusion adapted to cooperate with the other closure element to removably assemble the elements together. The protrusion is integrally formed with the tab, preferably by stamping. The tab is parallelepiped-shaped and connected to the rest of the wall by at least one side. The tab is connected to the rest of the wall by only two sides, either adjacent or opposite sides. The tab includes a flat surface and transition surfaces, preferably inclined, extending respectively between said two sides and the flat surface. The wall is made of aluminum or aluminum alloy, preferably anodized. The closure element is a cap, the wall is an inner wall of the cap, and the other closure element is a ring of the container.The closure element comprises an outer cap and an inner cap mounted inside the outer cap, and the inner wall is an inner wall of the inner cap. The inner cap has a lower portion that fits against the inner wall of the outer cap, and an upper portion that is detached from the inner wall of the outer cap. The closure element is a ring adapted to be fixed to the container.

[0010] A complete set of closures for cosmetic product containers is also offered, including: the closing element defined according to one or more of the above characteristics; and the other closing element, the closing element cooperating with the other closing element between a closed position and an open position, either of the closing element and the other closing element being suitable to be associated with the cosmetic product container.

Description of the implementation methods

[0012] The drawings and description below contain, for the most part, elements of a definite nature. They can therefore not only serve to better explain the present invention, but also contribute to its definition, if necessary.

[0013] Reference is now being made to the Figure 1 which shows a closure set 9 of a containing 10 for cosmetic products. The closure assembly 9 includes a closure element in the form of a hood 14, and another closing element in the form of a ring 12 of container 10. The two closing elements are adapted to cooperate with each other. The ring 12 cooperates with the cap 14 between a closed position and an open position (illustrated in the figure 1 The ring and the cap 14 are two independent items that can be assembled together or not, depending on whether access to the cosmetic product is desired. The ring 12 can be a part attached to the container 10, such as a collar on a perfume bottle, or it can be entirely formed from the container, such as a section (plastic or otherwise) of a lipstick-type container.

[0014] A cosmetic product container can be any container that holds a liquid, semi-liquid, or solid cosmetic product. For example, perfume, lipstick, cream jar, mascara, lip gloss, or nail polish—the list is not exhaustive. It can be made of various materials: glass, metal, or plastic, for example. In the example of the Figure 1 Container 10 is a lipstick (illustrated with dotted lines) and the cosmetic product is a lipstick grape 16. In the example of the Figure 2 Container 10 is a perfume bottle 110 (shown in dotted lines). A closure assembly 109 for container 110 is similar to assembly 9, and includes a hood 114 and one ring 112 associated. The cover 114 protects a mechanism of exemption mechanism 118The perfume bottle, in this case a spray diffuser, is a container. The ring 112 is a collar arranged around the neck 113 of the perfume bottle. The cap 114 and ring 112 can have any of the embodiments discussed below for the cap 14 and ring 12 (and vice versa). In what follows, the example of the lipstick 10 or the example of the perfume bottle 110 will be used alternately to illustrate different embodiments of the closure assembly, without the described cap and / or ring and / or closure assembly being related to the type of container. The word "ring" is used in this description to indicate a part of the container (attached or not) with which the cap cooperates, without implying that this part has a particular shape, such as, for example, a ring. The cap can be any means of closing a cosmetic product container, for example, a cap, a stopper, or a lid.

[0015] Container 10 shown in dotted line at the Figure 1 is a lipstick case. The cap 14 serves to protect the lipstick bullet 16 from the container 10. When the cap 14 is in a closed position, i.e., assembled with the container 10, the lipstick bullet 16 is protected from the external environment. When the cap 14 is in the open position (as illustrated in the figure 1 ), grape 16 is exposed and accessible for application by a user.

[0016] Container 10 also includes part of a mechanism 18 of exemptionof lipstick. The dispensing mechanism 18 is a traditional lipstick dispensing mechanism and will not be discussed in detail here. The lipstick bullet 16 can be fixed to the rest of the container 10, so that when the lipstick is finished, the entire container 10 can be discarded. In another embodiment, the lipstick bullet 16 (and possibly part of the dispensing mechanism 18) can be removable from the container 10, so that the bullet, when finished, can be replaced with another bullet compatible with the container 10, without discarding the container 10. The ring 12 is arranged around a base 13 lipstick, which is used to put the dispensing mechanism 18 into action.

[0017] The assembly of the lid 14 onto the container 10 is typically done by sliding one towards the other. (direction of movement D1),This results in friction between the two parts until the cover 14 is engaged on the ring 12. The cover 14 is reversibly fitted onto the ring 12 by friction. It can be disassembled from the ring 12 by sliding it in a direction of travel D2 inverse to D1. As will be discussed below, the assembly, according to certain embodiments, can also be done by elastic interlocking between the ring 12 and the cover 14, i.e. by clipping.

[0018] The cover 14 and the associated ring 12 are shown here as having a circular cross-section. However, the cover 10 and the ring 12 could be of different shapes, such as elliptical, square, or hexagonal cross-section.

[0019] With reference to the Figure 3The cap 14 and its interaction with the ring 12 to ensure the reversible closure of the container 10 will be discussed in greater detail. As mentioned above, the characteristics of the cap 14 of the lipstick container 10 are applicable to the cap 114 for the perfume bottle container 110. To avoid making the text cumbersome, similar numerical references, but in hundreds of different categories, will be used to describe different embodiments of the cap (applicable to any cosmetic product container) without describing the same elements in detail again.

[0020] The assembly of the lid 14 onto the container 10 is carried out between a inner wall 20 The cap 14 and the ring 12 of the container 10 are translated by one upon the other along the directions of movement D1, D2. The ring 12, with which the inner wall cooperates, can be made of various materials. It can be, for example, metallic, plastic, or glass.

[0021] According to one embodiment, the internal wall 20 is an internal wall of a internal hood 32, and the hood 14 is then the assembly of the internal hood 32 and a external cover 34 serving as a trim piece mounted on the outside of the inner cover 32. The two can be fixed together, for example with glue, or simply held firmly together by friction. The outer cover 34 can be made of any material and have any desired shape. The outer cover 34 allows the inner cover 32 to be hidden from the user's view.

[0022] The inner wall 20 has one or more 24 connection zones metallic and elastically deformable. The connection areas 24, by deforming elastically when they meet the ring 12, allow multiple interlocking and dislocking of the cover 14 on the ring 12 between the closed and open positions.

[0023] According to an embodiment of the present invention, the connection zones 24 are integrally formed with the inner wall 20 such that the inner wall and the connection zones 24 are made of the same metallic material. In an embodiment not included in the present invention, the connection zones 24 are attached to the inner wall 20, for example, by welding if the inner wall 20 is metallic, or by gluing or by a fixed interlocking mechanism (for example, clipped or captive connection). In these latter embodiments, the inner wall 20 may be metallic or plastic.

[0024] In the implementation of the figure 3The inner wall 20 of the cover 14 has three connection zones 24 equidistant from each other (one visible and another partially visible). However, the inner wall 20 may have just one, two, or more than three connection zones 24. The number and positions of the connection zones 24 may depend on the shape of the cover 14 and the desired degree of resistance to opening. For example, if the cover 14 has a square cross-section, the connection zones 24 may be located on two opposite sides of the inner wall 20 of the cover 14.

[0025] In what follows, a single connection zone 24 will be described as an example of an elastically deformable connection zone. The connection zones 24 of the same hood 14 may be identical to each other, or may be different from each other, for example by adopting one or more of the embodiments described below.

[0026] The shape and construction of the connection zone 24 are specifically chosen to allow reversible fitting of the cover 14 onto the ring 12, even though the inner wall 20 of the cover is metallic. For this purpose, the elastic deformation zone of the metal in the connection zone 24 is exploited. In one embodiment, each of the connection zones 24 comprises a connection tab 26 The tab 26 is elastically deformable and partially detached from the rest of the inner wall 20. It is adapted to cooperate elastically with the ring 12 to repeatedly assemble the cover 14 to the ring 12. The tab 26 deforms during the assembly and disassembly actions of the cover 14 on the ring 12 without losing its original shape once at rest (i.e., when the cover 14 is disengaged from the ring 12).

[0027] Metal is known to be a plastic material, meaning that when deformed, it retains a non-initial, deformed shape even after the deforming force is removed. However, under certain low deforming forces, metal has a zone of elastic deformation within which, when deformed, it returns to its original shape after the deforming force is removed. The connection area 24, particularly the tab 26, has sizes and shapes chosen so that the tab 26 remains within the elastic deformation zone of the metal constituting it when the cover 14 is assembled to the ring 12.

[0028] According to one embodiment, the internal cover 32 comprises a cylindrical body and has a closed end 33. According to one embodiment, the internal cover 32 fits a inner wall 36 of the external cover 34. In the example of the figure 3, the internal hood 32 has its closed end 33 at a distance of one closed end 37 of the external cover 34. One space 35 The space between the closed ends of the inner hood 32 and the outer hood 34 could, for example, be used to weight the hood 14. The inner hood 32 could, however, at its closed end 33, touch the outer hood 34. In the example of the Figures 4 and 5 The covers 114, 214 are formed of internal covers 132, 232 whose closed end touches that of the external cover 134, 234. According to another embodiment, the internal cover can be detached in places from the internal wall of the external cover. Figures 5 , 6 and 7 show examples of internal hoods 232, 332 having a lower part 231, 331 which fits snugly against the inner wall of the outer cover, and a upper part 235, 335 which is detached from the inner wall of the outer cover. In the example of cover 214 of the figure 5 And 6, the entire upper part 235 of the inner cover 232 is detached from the inner wall 220 of the outer cover 234, so as to form a crown 239 reinforced compared to the lower part 231. In the example of the figure 7 , only discrete portions of the upper part 335 of the inner cover 332 are detached from the inner wall of the outer cover, such as for example the three portions 339. The choice between different internal hood shapes can also be made based on the areas where the hood should rest against the container. For example, in the example of the figure 4 , a lower end 113 The cap 114 contacts the perfume bottle 110, whereas in the example of the figure 5 , a lip created by the crown 239 allows the cover 214 to be supported on the ring 112, so as to create a distance between a lower end 213of the hood 214 (the open end of the hood) and the container 110. According to another embodiment, the inner hood 32 is a sheath, open at each end.

[0029] With further reference to the figure 3 The connection area 24 (and therefore the tab 26) is preferably made of aluminum or an aluminum alloy, preferably anodized. The connection area 24 could also be made of steel, or even stainless steel.

[0030] According to one embodiment, the inner cap 32 and the connection area 24 (and therefore the tab) are formed entirely from metal as discussed above. In this case, the inner cap 32 is formed by stamping from a sheet of the metal material. The tab 26 can be formed in the extruded inner cap 32 by cutting and stamping. For this, one or more 30 incisionsare made in the inner wall 20 and the cut shape is deformed by stamping to move away and be partially detached from the rest of the inner wall 20, thus forming the tongue. In the example of the figure 3 Two opposing straight incisions 30 are made to form the tongue 26. Several tongue shapes and incisions are possible. Various examples will be given below.

[0031] Several factors influence the design of a tongue to make it elastically deformable despite being made of metal. These factors include, but are not limited to: the size of the tongue, the size of the incisions relative to the size of the sides to which the tongue is attached, the thickness of the tongue, the surface area of ​​the tongue relative to the size of the sides to which it is attached, and the material. Thus, a tongue with large incisions will be more adaptable to deformation than a tongue with small incisions (all other factors being equal). For example, a rectangular tongue with incised long sides will be more flexible than a tongue of the same shape and size with incised short sides. If the tongue is subjected to excessive deformation, the deformation can become plastic, meaning irreversible. In this case, the elastic interlocking connection will no longer be possible.If, on the other hand, the tongue is subject to too little or no deformation, elastic interlocking will also not be possible. Thus, the tongue is designed to be neither too deformable nor too rigid, so as to remain within the elastic deformation range of the material.

[0032] According to one embodiment, the tab 26 further comprises a protuberance 27adapted to cooperate with the ring 12 to assemble the cover 14 to the ring 12. The protrusion 27 provides additional frictional engagement for the ring 12. Each tab 26 could have more than one protrusion 27, such as two adjacent protrusions, or no protrusion at all. If the cover 14 includes several tabs, only some of the tabs might have the protrusion. The protrusion 27 can be integrally formed with the tab 26, for example by stamping. In another embodiment, the protrusion 27 is an added part to the tab 26, for example by bonding, or a spot weld to the tab 26.

[0033] The protuberance 27 illustrated in Figure 3 is shaped like a grain of rice. However, the protrusion could have various shapes, such as a disc or a bar. The protrusion 27 may be located in the middle of the tongue, as illustrated in the figure 3, or at the edge of the tongue as illustrated in the figure 8 .

[0034] According to another embodiment, the tongue could have a recess instead of or in addition to the protrusion 27 which would cooperate with a protrusion of the ring.

[0035] To ensure reversible interlocking and elastic deformation of the tab 26, an internal diameter D1 of the inner cap 32 can be significantly larger than a diameter D2 of the ring 12 to ensure friction between the two. For example, the interference between the ring 12 and the inner wall 20 of the inner cap 32 is approximately 0.3 mm. The internal diameter D1 of the inner cap 32 is calculated as the smallest distance between two opposite points on the inner wall 20. This is, for example, a tab-to-tab distance or a protrusion-to-protrusion distance if the tab has a protrusion.

[0036] The ring 12 can have several shapes chosen to cooperate with the cap 14. The ring 12 can be smooth (like the ring 12 illustrated in the Figures 1 , 2 or ring 112 of the Figures 4 and 5 ) and the connection between the cap 14 and the ring 12 is then ensured by simple friction of the tab on the ring. According to another embodiment, the ring 12 may have indentations or protrusions (ring or groove) adapted to cooperate with the tab, to provide friction by elastic interlocking. For example, the figure 8 illustrates a ring 412 having a protuberance 442.The protrusion 442 can be discrete, so that, for example, the ring 412 has a series of circumferentially arranged protrusions. This protrusion 442 can also be annular on the ring 412. There could also be several annular protrusions. The protrusion 442 can cooperate with a groove in a tab of a cover. The ring protrusion can also cooperate with a protrusion on the tab, as in the example of the figure 8 where the protrusion 442 of the ring 412 cooperates with a protuberance 427 of a tab 426. According to another example, as illustrated in the figure 9 , a ring 512 presents a gorge 542. The 542 groove, for example, is annular and adapted to cooperate with a protuberance 527 of a tongue 526 of a hood 514.

[0037] The tongue can have several shapes. In the example of the Figure 3The tongue 26 is rectangular. It is connected to the rest of the internal wall 20 by only two of its sides. two short opposite sides 52, and detached from the inner wall 20 by two opposite long sides 54. The sides by which the tab 26 is connected to the rest of the inner wall 20 are preferably sides transverse to the directions of movement D1, D2 of the cover 14. In the example of the figure 3 The opposite long sides 54 of the tongue 26 are arranged parallel to the directions of movement D1, D2 and are also the incised sides, and therefore detached from the inner wall 20. According to one embodiment, the tongue 26 has two transition surfaces 58 extending from the short sides 52 and one flat surface 59.The flat surface 29 accommodates the protrusion 27. When the tab has no protrusion, the flat surface corresponds to a contact area with the ring. When the tab has a protrusion, the protrusion is a contact area with the ring. The transition surfaces 58 ensure a gradual transition between the largest diameter of the inner wall 20, i.e., diameter D3, and the smallest diameter of the inner wall 20, i.e., diameter D4, corresponding to the diameter at the tab 26, and more precisely at the protrusion 27 if the tab 26 has such a protrusion. In this embodiment, the transition surfaces 58 are inclined surfaces. However, it is possible that the transition surfaces 58 are curved surfaces allowing a gradual transition between the inner wall 20 and the flat surface 59.The tongue 26 might not have the inclined surfaces 58, so that the transition between the inner wall 20 and the flat surface 59 is like a step. The tongue 26 might also not have a flat surface and be convex.

[0038] The tongue 26 could alternatively be connected by the opposite long sides 54. In this case, the tongue 26 would preferably be arranged on the inner wall 20 so that the long sides 54 are transverse to the directions of movement D1, D2. The Figure 10 shows a tongue 626 with such a configuration. The 626 tongue is rectangular and has two short odds 654 arranged in a direction parallel to the displacement directions D1, D2 (the short sides are disconnected from the inner wall), and two long sides 652(the long sides are connected to the rest of the inner wall) in a direction transverse to the displacement directions D1, D2. Similar to tongue 26, tongue 626 has a flat surface 659 and two inclined surfaces 658 extending between each of the short sides 654 and the flat surface 659. Similar to the tongue 26, the inclined surfaces 658 could be omitted. The tongue 626 includes a protuberance 627 on the flat surface 629. The protuberance 627 similar to that described below and its alternatives, could be omitted.

[0039] The parallelepiped-shaped tongue could alternatively be connected to the inner wall by adjacent sides rather than opposite sides. Such tab 726 of cap 714 is illustrated at the figure 11 The 726 tongue is connected to the rest of the inner wall by two adjacent sides 752 and detached from the inner wall by the other two adjacent sides 754. Preferably, and as illustrated in the figure 11 , the side of the tongue 726 which is connected to the inner wall and which is transverse to the directions of movement D1, D2 is a proximal side to a open end 713 of cap 714.

[0040] According to another embodiment, the parallelepiped-shaped tab can also be connected on three sides. Such a tongue 826 of cap 814 is illustrated at the figure 12 The 826 tongue is connected to the rest of the inner wall by three adjacent sides 852 and detached from the inner wall by a side 854. Preferably, and as illustrated in the figure 12 , the side 854 of the tongue 826 which is disconnected from the inner wall is a side parallel to the directions of displacement D1, D2.

[0041] According to another embodiment, the parallelepiped-shaped tab can also be connected on only one side.

[0042] According to another embodiment, the parallelepiped-shaped tab can be positioned so that one or more of its sides are at a non-zero, non-perpendicular angle with the displacement directions D1, D2. Such tongue 926 of 914 cap is illustrated at the figure 13 Preferably, and as illustrated in the figure 13 , the sides of the 926 tongue which are disconnected from the inner wall 920 are distal sides 954 has the open end 913 of the 914 cap, and the sides of the 926 tab which are connected to the inner wall 920 are proximal sides 954 has the open end 913 of cap 914. It is possible that the tab is disconnected by only one of the two distal sides 954. Although this is not the case for tab 926 shown in the figure 13 , tongue 926 could have characteristics of the other tongues discussed above, such as transition surfaces.

[0043] The tabs described above and illustrated in the figures 3 to 13 are positioned at a distance from the open end of the cap. However, it is possible that the tab has one side positioned at the level of the open end of the cap. Such a tongue 1026 of cap 1014 is illustrated at the figure 14 The tongue 1026 is formed by two incisions 1030 in the inner wall 1020 who communicate with a open end 1013 (i.e., the proximal end to the container 10) of the cap 1014. The tab 1026 is connected to the rest of the inner wall 1020 by a single side 1054, distal to the open end 1013 of the cap 1014. Although not the case for the illustrated tab 1026, according to one embodiment, the tab 1026 could include an inclined or transitional surface similar to those described above, between the side 1054 and a flat surface of the tab 1026.

[0044] In another embodiment, the tongue is not parallelepiped-shaped. An example of such a tongue 1126 of hood 1124 is illustrated at the Figure 15 The tongue 1126 is circular in shape and connected to the rest of the inner wall by an arc. For example, the arc is a semicircle or three-quarters of a circle. In another example, the tongue 1026 is detached from the rest of the inner wall 1120 at several points on the circle. It may, for example, be connected to the rest of the inner wall at three points or zones equidistant from the circle. The circular shape is not necessarily a circle. The circular shape could be an oval or any other curved shape. Preferably, and as illustrated in the figure 15 The tongue 1126 is connected to the rest of the inner wall 1120 by a portion 1154 proximal to the open end 1113 of the cap 1114. The disconnected portion could have a rim as illustrated in the figure 15 .

[0045] The connecting tab could have a shape comprising curved parts and straight parts, forming in a way a mixture of the above embodiments.

[0046] Throughout the preceding discussion, a closure assembly has been illustrated in which the closing element that includes the elastic deformation zone (and thus the tab) is the hood. However, it is possible that the closing element that includes the elastic deformation zone is the ring, so that the closing capacities of the hood and the ring are reversed compared to what has been described so far. Thus, without repeating the above, the ring would have an outer wall similar to the inner wall described below and one or more elastically deformable connection zones as discussed above. The inner hood cooperating with such a ring having elastic deformation zones would then have the characteristics described above for the ring, such as a protrusion or groove, or a smooth wall.It is also possible that each of the closing elements (hood and ring) has elastic deformation zones so as to cooperate with each other.
