Description

[Technical Field]

[0001] The present invention relates to the field of fluid or paste cosmetic application devices, such as application devices for mascara-type products.

[0002] The present invention more particularly has the object of enabling a method for manufacturing a cosmetic application device, a cosmetic application device, and a cosmetic dispensing device. [Background technology]

[0003] Mascara-type fluid or paste cosmetic dispensing devices are typically used until the entire cosmetic contained in the cosmetic dispensing device is used up. Once emptied, the dispensing device set is typically discarded, potentially clogging disposal systems. It would be of interest to support the reuse of these devices and the application apparatuses they contain for more durable applications.

[0004] In practice, modern dispensing devices comprise many different components, generally five components (bottle, cap, rod, applicator, wiper), made of different materials, such as elastomers and thermoplastics, in order to obtain the expected properties of these components, in particular with regard to stiffness and elasticity. For this reason, when it is desired to reuse these dispensing devices, this becomes particularly complicated, since the different materials used must be separated in order to be reused separately.

[0005] Although there are manufacturing methods that allow reducing the number of elements constituting the application device or the number of materials used, such as those taught by documents FR3003736A1, US Patent Application No. 2016 / 051032(A1) and US Patent Application No. 2021030487(A1), these methods are not entirely satisfactory because the use of various materials to manufacture the application device makes it difficult to reuse the discharge devices described in these documents. [Prior art documents] [Patent documents]

[0006] [Patent Document 1] FR3003736A1 [Patent Document 2] U.S. Patent Application No. 2016 / 051032(A1) [Patent Document 3] U.S. Patent Application No. 2021030487(A1) [Patent Document 4] U.S. Patent Application No. 2019014895(A1) Summary of the Invention [Problem to be solved by the invention]

[0007] The object of the present invention is to ameliorate at least some of the problems mentioned hereinabove, and therefore the present invention has the object of making it possible to provide an applicator assembly that makes it possible to support reuse.

[0008] The present invention also has the object of aiding in the manufacture of applicator assemblies with the aim of limiting the number of assembly steps typically employed in prior art methods. [Means for solving the problem]

[0009] To this end, the present invention relates to a method for manufacturing a cosmetic application device assembly, comprising the following steps: - forming a rod / cap element and a brush using two material manufacturing techniques, the rod / cap element comprising a skirt adapted to cooperate with a neck of a bottle and a rod extending from the skirt and having a second end opposite the skirt, the second end and the brush being integrally formed, the brush comprising a core and at least one first row of bristles extending from the core; the rod / cap element and the brush are made respectively of first and second polymeric materials that are different from each other and compatible with each other for reuse, said rod / cap element and brush together forming a cosmetic application device assembly;

[0010] By using such a manufacturing method, the applicator assembly is manufactured in a single step without the need to employ an assembly step. This therefore aids in the manufacture of the applicator assembly. Furthermore, by having the brush and cap / rod element made of a material compatible for reuse, handling (reuse) of the applicator assembly is aided because no disassembly step is necessary. Such disassembly, which is precluded to enable such handling, is further prevented by the fact that the cap / rod element and the brush are integrally formed. For this reason, reusing an applicator assembly made by such a method is particularly advantageous over prior art applicator assemblies.

[0011] Two-material manufacturing techniques are understood to mean techniques that allow the manufacture in one step of one or more elements from at least two different materials. These manufacturing techniques include, in particular, co-molding, over-molding in one step, and co-extrusion. It will be noted that, according to the present invention, the materials can be different materials obtained from the same resin with different hardness or color, or resins of the same class of material that can be recycled.

[0012] Compatible with respect to recycling means that the presence of these materials in the same object does not interfere with recycling the materials. Thus, according to one embodiment of the present invention, each of the first and second materials may be selected from one of a class of materials known to not interfere with recycling, including polyethylene terephthalate and polypropylene.

[0013] The second end of the rod may include a tensioner, with the core extending at least partially around the tensioner.

[0014] Such a tensioner makes it possible to increase and adjust the stiffness of the brush depending on the characteristics required for the application of the cosmetic product.

[0015] The present invention further relates to a cosmetic applicator assembly including a rod / cap element and a brush, wherein the rod / cap element includes a skirt adapted to cooperate with a neck of a bottle and a rod extending from the skirt and having a second end, the second end and the brush being integrally formed such that the second end is at least partially housed within the brush, and the brush includes a core and at least one first row of bristles extending from the core;

[0016] The rod / cap element and the brush are constructed from first and second polymeric materials, respectively, that are different from one another and compatible with one another for reuse.

[0017] Such an applicator assembly according to the invention has the advantage of supporting reuse since the rod / cap element can be reused together with the brush, and any risk of the rod / cap element and the brush becoming separated is prevented since they are formed in one piece with the applicator assembly.

[0018] The second end may include at least one recess in the brush, said recess preferably being a through opening.

[0019] The use of such recesses improves securing the brush and second end together because the brush has a portion that is directly received within the second end. The second end can include a tensioner, with the core extending at least partially around the tensioner.

[0020] Such a tensioner makes it possible to increase the stiffness of the brush and to adjust the stiffness of the brush by adapting the geometry of the tensioner.

[0021] A tensioner may extend along the longitudinal axis of the rod and may have a reinforcing portion extending in at least one direction relative to the longitudinal axis and over at least a portion of its length.

[0022] Such a reinforcing portion makes it possible to increase the stiffness of the brush in the direction of interest and therefore to mechanically adapt the brush depending on the cosmetic product to be applied and the geometry of the brush.

[0023] The reinforcing portion may have a cross section that varies along the longitudinal axis.

[0024] Such a varying cross section makes it possible to vary the mechanical properties of the brush and its bristles along the brush, thus enabling precise modification of the mechanical properties of the brush over its entire length.

[0025] The tensioner may further include at least one second reinforcing portion extending in at least one other radial direction relative to the longitudinal axis, and the tensioner preferably includes a third reinforcing portion extending in a radial direction different from the radial direction and the other radial direction.

[0026] Such reinforcements make it possible to fine-tune the mechanical behavior of the brush during application of the cosmetic product.

[0027] The tensioner may include at least one central portion extending along the longitudinal axis of the rod and at least one second row of bristles projecting from the central portion.

[0028] Such bristles in the second row have mechanical properties that are distinctly different from the mechanical properties of the bristles disposed directly on the brush because the bristles in the second row are made of a separate material (the first material), thus making it possible to provide two or more types of bristles on the brush in order to obtain the properties required for cosmetic application.

[0029] It will be noted that such central portion forms the tensioner body, and the bristles of the second row may of course extend directly from the central portion or body, or may extend indirectly from the central portion by extending from reinforcing portions which themselves extend from the central portion.

[0030] At least some of the bristles of the second row protrude through the core.

[0031] At least some of the bristles of the second row are extended by respective bristles of the brush, said bristles being either included or not included in the bristles of the first row.

[0032] These two distinct configurations of the bristles of the second row provide distinct brush properties, and therefore a particularly wide range of bristle mechanical properties is possible with the applicator assembly according to the invention.

[0033] The present invention further relates to a cosmetic dispensing device, comprising: - a cosmetic application device assembly according to the present invention; a bottle including a neck portion, the skirt of the rod / cap element being adapted to cooperate with the neck portion of the bottle; - The wiper inside the bottle; Includes.

[0034] Such devices benefit from the advantages associated with the cosmetic applicator assembly they contain.

[0035] The cosmetic dispensing device may further include a cap adapted to close the skirt of the rod / cap element on the opposite side of the rod.

[0036] Apart from possibly closing the skirt, such a cap makes it possible to enclose the cosmetic applicator assembly if the skirt does not have a sealing wall.

[0037] The invention will be better understood on reading the description of an embodiment given purely by way of non-limiting indication and with reference to the accompanying drawings, in which: [Brief explanation of the drawings]

[0039] For purposes of facilitating transition from one figure to another, equal, similar or equivalent parts of the various figures will bear the same reference numerals.

[0040] In order to improve the legibility of these figures, the various parts shown in the figures are not necessarily drawn to uniform scale.

[0041] These various possibilities (variants and embodiments) are to be understood as not being mutually exclusive and can be combined with one another.

[0042] FIG. 1 depicts a cosmetic dispensing device 1 including an applicator assembly 100 according to a first embodiment of the present invention.

[0043] As shown in Figures 1 and 2A to 2D, such a dispensing device 1 comprises: an applicator assembly 10; a bottle 20 intended to contain a cosmetic product not bearing a reference number, adapted to cooperate with the application device assembly 100; a cap 30 adapted to plug the skirt 111 of the applicator assembly 100; - Wiper 40 and Includes.

[0044] The applicator assembly 10 according to the present invention includes a rod / cap element 110 and a brush 120. The rod / cap element 110 comprises: a skirt 111 adapted to cooperate with the neck 210 of the bottle 20; a rod 112 extending from the skirt 111 and having a second end 114 opposite the skirt 111; Includes.

[0045] In accordance with the present invention, the brush 120 and second end 114 are integrally formed.

[0046] 2D shows that the skirt 111 has a cylindrical shape with an open base. The skirt has a central wall from which the rod 112 extends, said central wall therefore coinciding with the first end of the rod 112. The central wall separates the skirt 111 into a first part 111A, through which the rod 112 extends, and a second part 111B, which is opposite the first part 111A and thus the rod 112. The first part 111A of the skirt 111 is configured to cooperate with the neck 210 of the bottle 20 and therefore includes two radial ribs 113 intended to cooperate with the threaded portion 23 of the neck to provide a bayonet closure in this first embodiment. Thus, as shown in Figure 2C, the bottle has two threaded portions 23 (or guides) for guiding and preventing movement of the rib 113 of the skirt 111 when the applicator assembly 10 is attached onto the bottle according to the bayonet closure principle.

[0047] The second part 111B of the skirt 111 includes a groove intended to allow a cap 30 to be fixed in order to close the second part of the skirt 111. In this variant of the first embodiment, the dispensing device 1 does not need to include a cap 30, since closure of the bottle 20 is achieved by the central wall 115.

[0048] Thus, if the dispensing device 1 according to the invention comprises only four elements, according to one possibility of the invention, the dispensing device 1 may comprise only three elements. Such a possibility is made possible by the applicator assembly 10 according to the invention, which makes it possible to create an integrally formed single component comprising the cap (skirt 111), the rod 112 and the brush 120. Furthermore, it is to be noted that the cap 30 may provide an enclosure for the applicator assembly 10 and may therefore carry a logo, a pattern or a decorative element.

[0049] 3A and 3B specifically depict applicator assembly 10 according to this first embodiment. Rod 112 extends from central wall 115 and is coaxial with skirt 111. Central wall 115 is therefore coincident with first end 114 of rod 112. Second end 114 of rod 112 and brush 120 are integrally formed.

[0050] To provide continuity between the brush 120 and the rod 112, the second end 114 can have a smaller cross section than the remainder of the rod 112, as shown in FIG. 4A , here taking the form of a flat at the second end 114. Similarly, to advantageously secure the brush 120 and the second end 114 together, the second end 114 can include an opening 114A, which is preferably a through opening; this opening or recess can be seen in particular in FIG. 5. Complementary to the flat at the level of the second end, the brush 120 itself has an end 121A with a complementary flat and an extension that passes through the opening 114A. The applicator assembly is therefore characterized by continuity between the rod 112 and the brush 120.

[0051] 4B, brush 120 extends from second end 114 and includes a core 121 and multiple rows of bristles 122 extending from core 121. Core 121 has an end 121A that is complementary in shape to second end 114. It will be noted that in this first example configuration, the brush includes an arcuate portion 123 and an extended portion 124, with each of arcuate portion 123 and extended portion 124 including a row of bristles 122. Of course, this configuration of brush 120 is provided merely as a non-limiting example.

[0052] In the context of the present invention, the rod / cap element 110 and the brush 120 are made of a first and a second polymeric material, respectively, that are compatible with recycling. Thus, according to one embodiment of the present invention, each of the first and second materials can be selected from one of the classes of materials that can be recycled from polyethylene terephthalate and polypropylene. Similarly, according to one embodiment of the present invention, at least the first and / or second material can be a polymeric material at least partially made from biomass or from a material obtained from a source of post-consumer recycled plastic (PCR), or even from a hybrid material made in part from biomass and in part from a source of post-consumer recycled plastic. It should be noted that, if both the first and second materials are composed of only one polymer, it is possible, without departing from the scope of the present invention, to envisage one or more minor components, such as a charge, that complement one or more major polymers. This or these minor components may preferably be selected in such a way that they do not interfere with the recycling of the first and second materials.

[0053] Of course, in the context of the present invention, if the rod / cap element 110 and the brush 120 have to be made of a polymer material that is compatible for recycling, the other elements of the dispensing device 1 are preferably made of a material having the same compatibility, so that separation of these elements is not necessary when the dispensing device 1 is to be reused. Thus, according to one possibility of the present invention, the rod / cap element 110, the bottle 20, and the cap 30 can all three be made of a first material or of the same type of material as the first material (in the case of the bottle 20 and the cap 30), and the brush 120 and the wiper 40 can be made of a second material or of the same type of second material (in the case of the wiper 40).

[0054] In accordance with the principles of the present invention, applicator assembly 10, as specifically depicted in FIGS. 3A and 3B, may be made by a method of manufacture including the following steps: - Formation of a rod / cap element 110 and a brush 120 using a two-material manufacturing technique, wherein the rod / cap element 110 comprises a skirt 111 adapted to cooperate with a neck 210 of a bottle 20, and a rod 112 extending from the skirt 111 and having a second end opposite the skirt 111, the second end 114 and the brush 120 being integrally formed, and the brush 20 comprises a core 121 and at least one first row of bristles 122 extending from the core 121.

[0055] 6A and 6B, particularly in the case of FIG. 6B, in cross-section, depict a second embodiment of applicator assembly 10 in which rod 112 includes an extended portion 116 at its second end 114 that extends in line with the remainder of rod 112 and includes a row of bristles 118. This second embodiment of applicator assembly 10 therefore differs from the first embodiment of applicator assembly 10 in that rod 112 includes extended portion 116 at its second end 114.

[0056] 6A to 6C, in this second embodiment, the second end 114 includes an extension 116 that extends over most of the length of the brush 120. Except for the part of its bristles that protrude from the core 121, the extension 116 is contained within the core 121. The comb formed by the rows of bristles 118 is responsible for applying the cosmetic product, thereby providing greater rigidity to the bristles 122 of the brush. This allows the user of the cosmetic dispensing device 1 to have two types of comb available, depending on the type of cosmetic application required.

[0057] Likewise, the extension 116 provides a significant stiffening of the brush 120, since a large portion of the core volume is occupied by the extension 116. In order to advantageously secure the brush to the second end 114 well, while at the same time enabling this stiffening of the brush 120, the second end 114 has, starting from the remainder of the rod 112 in the direction away from the skirt 111, a smaller first section including the opening 114A, and a flat portion extended by a rounded second section forming the extension 116 and including a row of bristles 118, as shown in Figure 7A. This rounded shape of the second section, shown in Figure 7B, allows good stiffness despite the tapered shape of the combination of the brush 120 and the second end in the direction away from the skirt 111.

[0058] The method of manufacturing the applicator assembly 10 according to this second embodiment differs from the method of manufacturing the applicator assembly 10 according to the first embodiment in that during the step of forming the rod / cap 110 and the brush 120, the formed rod / cap element 110 includes an extension portion 116.

[0059] 8A-8C depict a third embodiment of applicator assembly 10 that includes a tensioner 117 housed within core 121 of brush 120 at the second end of rod / cap element 110. This third embodiment of applicator assembly 10 differs from the first embodiment of applicator assembly 10 in that it includes a tensioner 117 housed within core 121 of brush 120 at the second end of rod / cap element 110.

[0060] Above and in the rest of this document, tensioner means an element of the rod 110 that is configured to allow control of the flexibility / stiffness of the brush, i.e. to create tension / stiffness in the brush. Such a tensioner is therefore intended to be housed in the core 121 of the brush 120 with the aim of providing a framework for the brush 120 without occupying a large part of the core's volume, as is the case with the extension 116 according to the second embodiment. Thus, as can be seen in Figure 8C, the tensioner 117 according to the invention generally has an area in the cross section of the brush 120 that is less than half or even less than one-third of the area of ​​the core 121.

[0061] In this third embodiment, as depicted in Figures 9A and 9B, rod 112 is extended at its second end 114 by tensioner 117. Apart from the presence of tensioner 117, second end 114 has a configuration similar to second end 114 of the applicator assembly according to the first embodiment. Figure 8B shows that tensioner 117 extends over most of the length of brush 120, here approximately three-quarters of the length of brush 120. As can be seen and discussed in the context of the variation of this embodiment depicted in Figures 10A and 10B, this extension of tensioner 117 is shown by way of example and can vary depending on the required stiffness characteristics of brush 120.

[0062] The tensioner 117 has a rounded cross section having a substantially semicircular shape. In this embodiment, the semicircular cross section of the tensioner 117 has a diameter that is less than half the diameter of the rod 111 between its two ends 114. With such a diameter, the tensioner 117 has a height that is less than one-quarter the diameter of the rod 111 between its two ends 114, as shown in FIG. 9A. Of course, these values ​​are given merely as an example. Generally speaking, the lateral dimension of the tensioner 117, excluding all reinforcement portions, is between 5% and 60% of the maximum lateral dimension of the remainder of the rod, and even more specifically, between 10% and 50% or between 20% and 40% of the maximum lateral dimension of the remainder of the rod.

[0063] Similarly, while the tensioner 117 can advantageously have a cross section that is substantially semicircular or rounded, as in this embodiment, it is also possible to envision the tensioner 117 having some other cross section without departing from the scope of the invention. Furthermore, even if in this embodiment the tensioner 117 has a constant cross section over its entire length, subsequent embodiments will show that it is entirely feasible to envision the tensioner 117 having a cross section that varies over its length depending on the required stiffness characteristics of the brush 120.

[0064] The method for manufacturing the applicator assembly 10 according to this third embodiment differs from the method for manufacturing the applicator assembly 10 according to the first embodiment in that during the step of forming the rod / cap element 110 and the brush 120, the formed rod / cap element 110 includes a tensioner 117.

[0065] 10A and 10B depict applicator assembly 10 according to a variant of the third embodiment, in which tensioner 117 has a shortened length. Thus, in this variant, tensioner extends over a length substantially equal to one-third of the length of brush 120. Thus, in the context of the present invention, brush 120 has a lower stiffness than brush 120 according to the third embodiment.

[0066] According to the present invention, the tensioner 117 can have a length between the length of the brush 120 and zero length, that is, the tensioner 117 can also have the configuration of the first embodiment in which the tensioner 117 is not provided.

[0067] For this reason, it is entirely feasible to envisage using in this embodiment a method for designing and manufacturing an applicator assembly, which comprises the following steps: - Determining the required stiffness of the brush, - determining the length of the tensioner 117 corresponding to the required stiffness; - manufacturing an applicator assembly 10 including a tensioner 117 having the tensioner length thus determined using a method for manufacturing applicator elements conforming to the third embodiment.

[0068] This makes it possible to adapt the stiffness of the brush 120 according to the properties required for an optimized application of the cosmetic product.

[0069] 11A and 11B, such a tensioner 117 may include a reinforcing portion 117A for the purpose of providing increased stiffness in a particular direction, such as in the direction of a brush containing a single row of bristles. Thus, the applicator assembly 10 according to such an embodiment differs from the applicator assembly 10 according to the third embodiment in that the tensioner includes a reinforcing portion 117A.

[0070] 11B, it can be seen that the tensioner 117 has, in its lower part, a reinforcing portion 117A in the form of a wall extending from the remainder of the tensioner 117, i.e., the semicircular cross-section body of the tensioner. In this embodiment, such a reinforcing portion 117A allows for increased stiffness in the direction of extension of the wall while maintaining relative flexibility in a direction perpendicular to this extension. In this embodiment, the reinforcing portion 117A extends from the body of the tensioner 117 over a height substantially equal to one-third of the diameter of the tensioner 117, i.e., the diameter of the semicircle forming its cross-section. This value is given purely by way of example; the reinforcing portion 117A can have a different extension height without departing from the scope of the invention. This extension height can therefore be, for example, between 10% and 50% of the tensioner 117, or even between 20% and 40% of this diameter. In the present embodiment, the width of said reinforcement portion 117A is substantially equal to one-sixth of the diameter of the tensioner 117, i.e. the diameter of the semicircle forming its cross section. It is entirely feasible to envisage other values ​​without departing from the scope of the invention.

[0071] Similarly, even though in this embodiment reinforcing portion 117A extends over the entire length of tensioner 117, it is equally conceivable that reinforcing portion 117A extends over only a portion of the length of tensioner 117 without departing from the scope of the present invention.

[0072] It should also be noted that such a reinforcing section makes it possible to reduce the thickness of the core 121 at the height of said reinforcing section 117A, and thus to limit the influence of the core 121 on the row of bristles 122 formed opposite the reinforcing section 117A. The row of bristles 122 formed opposite the reinforcing section 117A in this way has an increased stiffness compared to the row of bristles when the core has an unreduced thickness.

[0073] The applicator assembly 10 according to this fourth embodiment can be manufactured by a manufacturing method that differs from the method for manufacturing the applicator assembly 10 according to the third embodiment in that the tensioner 117 includes a reinforcing portion 117A during the steps of forming the rod / cap element 110 and the brush 120.

[0074] 12A and 12B depict rod / cap element 110 of a fifth embodiment applicator assembly 10 in which tensioner 117 includes two reinforcing portions 117A, 117B that extend radially away from one another. Thus, this fifth embodiment applicator assembly 10 differs from the fourth embodiment applicator assembly 10 in that tensioner 117 includes a second reinforcing portion 117B that extends radially away from reinforcing portion 117A, which becomes first reinforcing portion 117A.

[0075] Thus, in particular with the aim of providing asymmetric stiffness, in this fifth embodiment it is possible to provide the first reinforcing portion 117A and the second reinforcing portion 117B so as to be aligned with one another around the body of the tensioner 117. In this fifth embodiment, the second reinforcing portion 117B extends over a height that is substantially twice the height of the first portion 117A. This double extension height is made possible in this fifth embodiment in particular by the fact that the second reinforcing portion extends from a semicircular cut-out surface of the tensioner 117 in cross section. Of course, depending on the geometry of the tensioner 117 and the orientation of the first reinforcing portion 117A and the second reinforcing portion 117B, the ratio of the heights of the first and second reinforcing portions may also be different, and therefore the second reinforcing portion 117B may also have the following extension heights without departing from the scope of the invention: in the range from the extension height of the first portion 117A to 3 times the extension height of the first portion 117A, or even in the range between 1.5 and 2.5 times the extension height of the first portion 117A; Alternatively, in the range from the extension height of the first portion 117A to one-quarter of the extension height of the first portion 117A, or even in the range between one-third and two-thirds of the extension height of the first portion 117A.

[0076] The applicator assembly 10 according to this fifth embodiment can be manufactured by a method of manufacturing the applicator assembly 10 that differs from the method of manufacturing the fourth embodiment in that the tensioner 117 includes a first reinforcing portion 117A and a second reinforcing portion 117B during the steps of forming the rod / cap element 110 and the brush 120.

[0077] 13A-13C depict the cap / rod element 110 of a sixth embodiment applicator assembly 10, in which the tensioner 117 includes a first reinforcing portion 117A and a second reinforcing portion 117B that extend radially at 120° from each other. This sixth embodiment applicator assembly 10 differs from the fifth embodiment applicator assembly 10 in that the first reinforcing portion 117A and the second reinforcing portion 117B extend radially at 120° from the circular portion of the tensioner 117, and the first reinforcing portion 117A and the second reinforcing portion 117B have the same dimensions.

[0078] The arrangement of the first reinforcing portion 117A and the second reinforcing portion 117B with the tensioner 117 of this configuration provides good rigidity in the two extension directions of the first reinforcing portion 117A and the second reinforcing portion 117B.

[0079] The applicator assembly 10 according to this sixth embodiment can be manufactured using a manufacturing method that differs from the method for manufacturing the applicator assembly 10 according to the fifth embodiment in that during the forming steps of the rod / cap element 110 and the brush 120, the first reinforcing portion 117A and the second reinforcing portion 117B extend radially at 120° from the circular portion of the tensioner 117.

[0080] 14A-14C depict a seventh embodiment of applicator assembly 10 in which tensioner 117 includes three reinforcing portions 117A, 117B, and 117C at 120° from one another, with one of these reinforcing portions, reinforcing portion 117C, having an extended height that varies along the length of rod / cap element 110. This seventh embodiment of applicator assembly 10 differs from the sixth embodiment of applicator assembly 10 in that there is a third reinforcing portion 117C at 120° from the first and second reinforcing portions, and this third reinforcing portion 117C has an extended height that varies along the tensioner 117.

[0081] 15A to 15D, it can be seen that the third reinforcing portion 117C has a varying extension height along the tensioner, transitioning from a height of zero to a maximum height substantially equal to the height of the first reinforcing portion 117A and the second reinforcing portion 117B. This varying extension height of the reinforcing portion 117C makes it possible to vary the thickness of the core 121 of the brush 120 at the height of a row of bristles 122 opposite this reinforcing portion 117C. This results in a sense of stiffness of the bristles 122 that varies along the row, with the cores 121 of the bristles 122 having a small thickness (maximum extension height) with reduced freedom of depression and therefore an increased sense of stiffness than bristles with a larger core 121 thickness (and therefore core 121 with maximal freedom of depression).

[0082] The first reinforcing portion 117A and the second reinforcing portion 117B have the greatest height along the entire tensioner 117, and for the same reason, the row of bristles 122 facing these two reinforcing portions 117A, 117B creates a feeling of greater stiffness compared to the bristles 122 of the brush that are offset from the reinforcing portions 117A, 117B, 117C.

[0083] The applicator assembly 10 according to this seventh embodiment can be manufactured by a manufacturing method that differs from the method for manufacturing the applicator assembly 10 according to the sixth embodiment in that during the forming step of the rod / cap element 110 and the brush 120, the tensioner 117 includes a first reinforcing portion 117A, a second reinforcing portion 117B, and a third reinforcing portion 117C associated with the seventh embodiment described above.

[0084] 16A and 16B depict rod / cap element 10 of applicator assembly 110 according to a variant of the seventh embodiment, in which first portion 117A and second portion 117B each include three through orifices that do not have reference numerals. Applicator assembly 10 according to this variant of the seventh embodiment therefore differs from applicator assembly 110 according to the seventh embodiment only in that first reinforcing portion 117A and second reinforcing portion 117B include the through orifices.

[0085] Such through orifices make it possible to advantageously fasten brushes 122 onto the first and second parts 114 of the rod / cap element 110. It will of course be noted that in the context of the present invention, and in all the described embodiments comprising a tensioner 117 comprising one or more reinforcing parts 117, 117A, 117B, 117C, it is entirely feasible to envisage that some or all of these reinforcing parts 117, 117A, 117B, 117C comprise one or more through orifices.

[0086] The applicator assembly 10 according to this variation of the seventh embodiment can be manufactured using a manufacturing method that differs from the method for manufacturing the applicator assembly 10 according to the seventh embodiment in that during the forming steps of the rod / cap element 110 and the brush 120, each of the first reinforcing portion 117A and the second reinforcing portion 117B includes three through orifices.

[0087] 17A-17D depict an eighth embodiment of applicator assembly 10, in which tensioner 117 includes three reinforcing sections 117A, 117B, and 117C at 120° angles to one another, with reinforcing section 117C including a row of bristles that are extended by the individual bristles of the brush. This eighth embodiment of applicator assembly 10 differs from the seventh embodiment of applicator assembly 10 in that third reinforcing section 117C has a fixed extended height and includes a row of bristles 122 that form a comb.

[0088] Thus, in a configuration similar to that of the extension portion 116 described in the context of the second embodiment, at least one reinforcing portion 117C can include a single row of bristles 118. As shown in Figure 17D, in this ninth embodiment, the brush 120 itself includes a single row of bristles 122 extending from the bristles of the third reinforcing portion. Thus, the brush 120 includes a type of "hybrid bristles" having a core reinforced by the bristles 118 of the third reinforcing portion 117C.

[0089] Similarly, as shown in FIG. 17D, the brush 120 further includes two rows of bristles having an increased stiffness feel opposite the first reinforcement portion 117A and the second reinforcement portion 117B.

[0090] The applicator assembly 10 according to this ninth embodiment may be manufactured using a different manufacturing method than the method for manufacturing the applicator 10 according to the eighth embodiment in that during the steps of forming the rod / cap element 110 and the brush 120, the third portion has a fixed extended height and includes the brush 118, which includes a row of bristles 122 including the "hybrid" bristles described hereinabove.

[0091] 19 depicts an applicator assembly 10 according to a variant of the ninth embodiment in an enlarged cross-section at the level of the brush 120, where the brush 120 includes alternating conventional bristles 122 at the level of a row of bristles 122 extending the bristles of the third reinforcing portion 117C. Thus, the applicator assembly 10 according to this variant embodiment differs from the applicator assembly 10 according to the ninth embodiment only in the presence of such alternating conventional bristles 122 in the row.

[0092] FIG. 19 shows that one row of bristles 122 of the brush includes alternating hybrid bristles 122 at the height of the third extended portion 117C, i.e., bristles having cores reinforced by the bristles 118 of the third extended portion 117C, and conventional bristles 122, i.e., bristles that do not receive the bristles 118 of the third reinforcing portion 117C.

[0093] The applicator assembly 10 according to this variation of the ninth embodiment may be manufactured using a manufacturing method that differs from the method for manufacturing the applicator assembly 10 according to the ninth embodiment in that during the steps of forming the rod / cap element 110 and the brush 120, the brush 120 includes alternating conventional bristles 122 at the height of a row of bristles 122 that extend the bristles of the third reinforcing portion 117C.

[0094] 20A and 20B depict a tenth embodiment of applicator assembly 10 in which tensioner 117 includes three reinforcing sections 117A, 117B, and 117C that are at 120° relative to one another, and each of these three reinforcing sections 117A, 117B, and 117C includes a row of bristles 118 extending therethrough. Applicator assembly 10 of the tenth embodiment further differs from applicator assembly 10 of the ninth embodiment in that first reinforcing section 117A and second reinforcing section 117B include separate rows of bristles 118 extending therethrough.

[0095] Indeed, it can be seen in Figure 20B that in this tenth embodiment, the bristles 118 of the first and second reinforcing portions 117A, 117B have a configuration similar to the configuration of the bristles 118 of the third reinforcing portion 117C described in the context of the ninth embodiment. Thus, in accordance with what has been described herein above with reference to the ninth embodiment, the brush 120 includes individual rows of bristles 122 extending from the rows of bristles of the first, second, and third reinforcing portions 117A, 117B, and 117C. The brush 120 therefore includes "hybrid bristles" in each of the reinforcing portions 117A, 117B, and 117C, having a core reinforced by the bristles 118 of those reinforcing portions 117A, 117B, and 117C.

[0096] The applicator assembly 10 according to this tenth embodiment may be manufactured using a manufacturing method that differs from that according to the ninth embodiment in that during the steps of forming the rod / cap element 110 and the brush 120, the first reinforcing portion 117A, the second reinforcing portion 117B, and the third reinforcing portion 117C each include bristles 118, and the brush 120 includes "hybrid bristles" in each of the reinforcing portions 117A, 117B, 117C having a core that is reinforced by the bristles 118 of those reinforcing portions 117A, 117B, 117C.

[0097] 22A-22D depict an eleventh embodiment of applicator assembly 10, in which tensioner 117 includes a row of bristles extending through the brush core. Thus, applicator assembly 10 of this eleventh embodiment differs from applicator assembly 10 of the ninth embodiment in that first reinforcing portion 117A and second reinforcing portion 117B have a smaller extended height, brush 120 does not include a row of bristles 122 opposite third reinforcing portion 117C, and the reinforcing row of bristles protrudes from core 121.

[0098] Thus, in this eleventh embodiment, according to possibilities similar to those of the extension portion 11 described in the context of the second embodiment, it is intended that the bristles 118 protrude from the core 121 and thus directly participate in dispensing the cosmetic. Thus, as already explained in the context of the second embodiment, the applicator assembly includes two types of bristles 118, 122: high-stiffness bristles associated with a first material and flexible bristles due to the use of a second material. The configuration of the bristles 118 at the height of the third reinforcing portion 117C is shown in Figures 23A to 23C.

[0099] The applicator assembly 10 according to this eleventh embodiment can be manufactured using a manufacturing method different from that according to the ninth embodiment in that during the steps of forming the rod / cap element 110 and the brush 120, the first reinforcing portion 117A and the second reinforcing portion 117B each have a smaller extended height, the brush 120 does not include bristles 122 at the height of the third reinforcing portion 117C, and the bristles 118 of the third reinforcing portion 117C protrude through the core 121 of the brush 120.

[0100] 24A through 24D depict a twelfth embodiment of applicator assembly 10, in which one end of tensioner 117 includes bristles 118E. Applicator assembly 10 according to the twelfth embodiment differs from applicator assembly 10 according to the fifth embodiment in that one end of the tensioner includes bristles 118E.

[0101] 25A to 25D, in this twelfth embodiment, the tensioner 117 has bristles 118E extending through it at its end opposite the skirt 111. It will be noted that in this twelfth embodiment, the bristles 118E are disposed in a plane defined by the semicircular truncation of the transverse cross section of the tensioner 117. There are five bristles 118E distributed at regular angular intervals.

[0102] The applicator assembly 10 according to this twelfth embodiment can be manufactured using a manufacturing method that differs from that according to the fifth embodiment in that the tensioner 117 includes bristles 118E at its end during the steps of forming the rod / cap element 110 and brush 120.

[0103] 26A through 26D depict a thirteenth embodiment of applicator assembly 10 in which tensioner 117 has bristles 118E extending through tensioner 117 in a three-dimensional distribution at its end opposite skirt 111. Applicator assembly 10 of the thirteenth embodiment differs from applicator assembly 10 of the twelfth embodiment in that bristles 118E at the end of the tensioner have a three-dimensional distribution.

[0104] Indeed, in Figures 27A to 27D, and particularly in Figure 27C, it can be seen that the bristles extend in line with the rest of the tensioner, so as to have an expansive or three-dimensional distribution.

[0105] The applicator assembly 10 according to this thirteenth embodiment can be manufactured using a manufacturing method that differs from that according to the twelfth embodiment in that during the steps of forming the rod / cap element 110 and the brush 120, the tensioner 117 has bristles 118E in a three-dimensional distribution at its end.

[0106] Of course, if the tensioner 117 is able to provide support for the bristles 118, 118E as well as for the reinforcing bristles associated with the bristles 122 of the brush 120 as complementary bristles for applying cosmetic products, as shown in various embodiments from the eighth embodiment onwards, the tensioner 117 according to the invention can likewise provide support for other elements of the brush 120, such as the arcuate portion 119, or the comb provided by the secondary reinforcing portion 117B, as will be described later in this specification with reference to Figures 28 to 31C.

[0107] 28A-28C thus depict a fourteenth embodiment of applicator assembly 10 according to the present invention, in which tensioner 117 includes an arcuate portion 119 containing a row of bristles 118. This fourteenth embodiment of applicator assembly 10 differs from the fifth embodiment of applicator assembly 10 in that tensioner 117 includes arcuate portion 119 in addition to first reinforcing portion 117A and second reinforcing portion 117B.

[0108] As shown in Figures 28B and 28C, the arcuate portion 119 begins at the remainder of the tensioner 117, i.e., the body of the tensioner 117, which is made of the first material, and extends along a curve between the two unlabeled ends of the brush 120. Thus, in Figures 28C and 29C, it can be seen that the arcuate portion 119 extends opposite the second reinforcing portion 117B. As shown in Figures 29A and 29B, the arcuate portion includes a row of bristles 118 on the opposite side of the remainder of the tensioner 117, i.e., the body of the tensioner 117. Because the row of bristles 118 is made of the first material, the bristles 118 in this row on the arcuate portion generally have a higher stiffness than the bristles 122 of the brush. It will be noted that the arcuate portions 119 and the bristles 118 they contain have a configuration similar to that taught in U.S. Patent Application No. 2019014895(A1).

[0109] The applicator assembly 10 according to this 14th embodiment can be manufactured using a manufacturing method that differs from the method for manufacturing the applicator assembly 10 according to the fifth embodiment in that the tensioner 117 includes the arcuate portion 119 according to the 14th embodiment during the forming steps of the rod / cap element 110 and the brush 120.

[0110] 30A-30C depict an applicator assembly 10 according to a fifteenth embodiment of the present invention, in which a tensioner 117 includes a non-referenced comb in a second reinforcing portion 117B that is provided by a non-referenced cutout in the second reinforcing portion 117B. The applicator assembly 10 according to the fifteenth embodiment differs from the assembly according to the fifth embodiment in that the second reinforcing portion 117B protrudes from the core 121 of the brush 120 and includes a cutout over at least a portion of its height that protrudes from the core 121, resulting in the second reinforcing portion 117B including the comb that protrudes from the core 121.

[0111] 31A to 31C, it can be seen that the second reinforcing portion 117B has an extension height relative to the rest of the tensioner 117, i.e., relative to the tensioner body, that decreases in the direction from the skirt 111 to the second end 114. The cutouts are uniformly distributed over the entire length of the second reinforcing portion 117B and are formed to a certain depth in said reinforcing portion 117B. The part of the second reinforcing portion 117B that protrudes from the core 121 therefore forms a comb that adopts the general frustoconical shape of the brush 120 according to this fifteenth embodiment.

[0112] Of course, this shape of the second reinforcing portion 117B and the cutouts is shown by way of example, and it is therefore entirely feasible to envisage that the second reinforcing portion 117B has a constant extension height over the entire length of the tensioner or that the cutouts have alternating first and second depths without departing from the scope of the invention.
