Description

Technical Field

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

[0002] The present invention more particularly relates to a method of manufacturing a cosmetic product applicator, a cosmetic product applicator, and a cosmetic product dispensing device. Background Art

[0003] Mascara-like fluid or paste-like cosmetic product dispensing devices are typically used until the cosmetic product they contain is completely consumed. Once used, the entire dispensing device is typically discarded, potentially clogging the disposal system. To ensure longer-term use of these devices and the applicators they contain, it would be beneficial to facilitate their recycling.

[0004] In reality, existing dispensing devices consist of several different components, typically five (bottle, cap, stem, applicator, wiper), made from different materials, such as elastomers and thermoplastics, to achieve the required properties for these elements, particularly in terms of stiffness and elasticity. Therefore, recycling these dispensing devices is particularly complex, as the different materials used must be separated for separate recycling.

[0005] Although there are some manufacturing methods that can reduce the number of elements constituting the applicator or the variety of materials used, such as the methods taught in documents FR3003736A1, US2016 / 051032A1 and US2021 / 030487A1, these methods are not entirely satisfactory because the use of different materials to manufacture the applicator makes it difficult to recycle the dispensing device described there. Summary of the Invention

[0006] The present invention aims to solve at least some of the problems mentioned above and therefore has as its object to provide an applicator assembly that allows for convenient recycling.

[0007] Another object of the present invention is to simplify the manufacture of the applicator assembly to reduce the number of assembly steps typically employed in prior art methods.

[0008] To this end, the present invention relates to a method for manufacturing a cosmetic product applicator assembly, comprising the following steps: - forming a stem / cap element and a brush portion using a dual-material manufacturing technique, the stem / cap element comprising a skirt adapted to engage the neck of the bottle, and a stem extending from the skirt and having a second end opposite the skirt, the second end being integrally formed with the brush portion, the brush portion comprising a core and at least one first row of bristles extending from the core; The stem / cap element and the brush are made of a first polymer material and a second polymer material, respectively, which are different from each other and compatible with each other in terms of recycling, and together form a cosmetic product applicator assembly.

[0009] This manufacturing method allows the applicator assembly to be manufactured in a single step, eliminating the need for assembly. This simplifies the manufacture of the applicator assembly. Furthermore, the brush and cap / stem element are made of recyclable materials, facilitating the disposal (recycling) of the applicator assembly by eliminating the need for disassembly. Furthermore, the integral formation of the cap / stem element and brush eliminates the need for disassembly that would prohibit such disposal. Consequently, applicator assemblies manufactured using this method are significantly more recyclable than prior art applicator assemblies.

[0010] Dual-material manufacturing techniques are technologies that enable one or more components to be manufactured in a single step from at least two different materials. These manufacturing techniques include, in particular, co-molding, single-step overmolding, and co-extrusion. It should 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 different materials obtained from resins of the same type that are recyclable.

[0011] Compatible with respect to recycling means that the presence of these materials in the same object does not affect their recycling. According to one embodiment of the invention, each of the first and second materials can thus be selected from one of the categories comprising polyethylene terephthalate and polypropylene, which are known not to affect recycling.

[0012] The second end of the rod body may include a tensioner, And the core extends at least partially around the tensioner.

[0013] Such a tensioner makes it possible to increase and adjust the stiffness of the brush according to the characteristics required for applying the cosmetic product.

[0014] The present invention also relates to a cosmetic product applicator assembly comprising a stem / cap element and a brush, wherein the stem / cap element comprises a skirt adapted to engage with a neck of a bottle, and a stem extending from the skirt and having a second end, the second end being integrally formed with the brush and at least partially received in the brush, the brush comprising a core and at least one first row of bristles extending from the core, The shaft / cap element and the brush are respectively composed of a first polymer material and a second polymer material that are different from each other and are compatible with each other in terms of recycling.

[0015] The applicator assembly according to the invention has the advantage of being easily recyclable, since the stem / cap element can be recycled together with the brush, and any risk of separation of the stem / cap element and the brush is avoided due to the integral structure of the applicator assembly.

[0016] The second end may comprise at least one recess in the brush portion, the recess preferably being a through hole.

[0017] By means of such a recess, the locking of the brush and the second end is improved, since the brush has a portion which is received directly in the second end.

[0018] The second end may include a tensioner, The core extends at least partially around the tensioner.

[0019] Such a tensioner makes it possible to increase the stiffness of the brush and to adjust the stiffness by adjusting the geometry of the tensioner.

[0020] The tensioner may extend along a longitudinal axis of the shank and have a reinforcement extending in at least one direction relative to the longitudinal axis and over at least a portion of its length.

[0021] Such a reinforcement makes it possible to increase the rigidity of the brush in the direction of interest, thus enabling a mechanical adjustment of the brush according to the cosmetic product applied and the geometry of the brush.

[0022] The reinforcement may have a cross-section that varies along the longitudinal axis.

[0023] This varying cross-section enables the mechanical properties of the brush portion and its bristles to be varied along the brush portion.Thus, the mechanical properties of the brush portion can be precisely refined over its entire length.

[0024] The tensioner may further comprise at least one second reinforcement extending in at least one other radial direction relative to the longitudinal axis, and preferably comprises a third reinforcement extending in a radial direction different from the radial direction and the other radial direction.

[0025] Such a reinforcement makes it possible to fine-tune the mechanical behavior of the brush during application of the cosmetic product.

[0026] The tensioner may include at least one central portion extending along the longitudinal axis of the shaft and at least one second row of bristles protruding from the central portion.

[0027] This second row of bristles has different mechanical properties than the bristles provided directly on the brush portion because they are made of a different material (the first material). Thus, more than one type of bristle can be provided on the brush portion to obtain the properties required for applying the cosmetic product.

[0028] It should be noted that such central portion forms the tensioner body and that the second bristle row may of course extend directly from said central portion (ie the body) or indirectly from said central portion, from a reinforcement which itself extends from said central portion.

[0029] At least a portion of the second bristle row protrudes through the core.

[0030] At least a portion of the second bristle row is extended by corresponding bristles of the brush portion, which bristles may or may not be included in the first bristle row.

[0031] These two different configurations of the second bristle rows provide the brush portion with different properties.Thus, the applicator assembly according to the invention allows a particularly wide range of mechanical properties of the bristles.

[0032] The present invention also relates to a cosmetic product dispensing device comprising: - a cosmetic product applicator assembly according to the invention, - a bottle comprising a neck, the skirt of the stem / cap element being configured to cooperate with said neck of the bottle, - A scraper located in the bottle.

[0033] Such a device benefits from the advantages provided by the cosmetic product applicator assembly it includes.

[0034] The cosmetic product dispensing device may further comprise a cap adapted to close the skirt of the stem / cap element on a side opposite the stem.

[0035] In addition to being able to close the skirt when the skirt lacks a sealing wall, such a cap is also able to close the cosmetic product applicator assembly. BRIEF DESCRIPTION OF THE DRAWINGS

[0069] Figure 1 A cosmetic product dispensing device 1 comprising an applicator assembly 100 according to a first embodiment of the present invention is depicted.

[0070] like Figure 1 and Figures 2A to 2D As shown, the dispensing device 1 comprises: - an applicator assembly 10; - a bottle 20 configured to cooperate with the applicator assembly 100 and to contain a cosmetic product (not marked with a reference number); - a cover portion 30 adapted to block the skirt portion 111 of the applicator assembly 100 ; and - Scraper 40.

[0071] The applicator assembly 10 according to the present invention comprises a stem / cap element 110 and a brush 120. The stem / cap element 110 comprises:

[0072] - a skirt 111 adapted to cooperate with the neck 210 of the bottle 20 ; and A stem 112 extending from the skirt 111 and having a second end 114 opposite the skirt 111 .

[0073] According to the present invention, the brush portion 120 and the second end 114 are integrally formed.

[0074] Figure 2D The skirt 111 is shown to have a cylindrical shape with an open bottom. The skirt comprises a central wall from which the stem 112 extends, so that the central wall coincides with a first end of the stem 112. The central wall divides the skirt 111 into a first portion 111A, in which the stem 112 extends, and a second portion 111B, opposite the first portion 111A of the skirt 111 and therefore also opposite the stem 112. The first portion 111A of the skirt 111 is configured to cooperate with the neck 210 of the bottle 20 and therefore comprises, in this first embodiment, two radial ribs 113 for cooperating with the threads 23 of the neck to provide a bayonet closure. Figure 2C As shown, the bottle thus comprises two threads 23 (or guides) for guiding and securing the ribs 113 of the skirt 111 when the applicator assembly 10 is mounted on the bottle according to the bayonet closure principle.

[0075] The second portion 111B of the skirt 111 comprises a groove for fixing the cap 30 to close the second portion of the skirt 111. In a variant of this first embodiment, the dispensing device 1 may not comprise the cap 30, since the closure of the bottle 20 is achieved by the central wall 115.

[0076] Thus, if the dispensing device 1 according to the present invention comprises only four elements, it can, according to one embodiment of the present invention, comprise only three elements. This possibility is enabled by the applicator assembly 10 according to the present invention, which makes it possible to produce a single, integrally formed component comprising the cap (skirt 111), the stem 112, and the brush 120. Furthermore, it should be noted that the cap 30 can provide the housing of the applicator assembly 10 and can therefore carry a logo, pattern, or decorative element.

[0077] Figure 3A and Figure 3B The applicator assembly 10 according to this first embodiment is specifically depicted. The stem 112 extends from a central wall 115 and is coaxial with the skirt 111. Thus, the central wall 115 coincides with a first end of the stem 112. The second end 114 of the stem 112 and the brush portion 120 are integrally formed.

[0078] To provide continuity between the brush portion 120 and the rod body 112, as Figure 4A As shown, the cross section of the second end 114 can be smaller than the rest of the rod body 112, and here it is in the form of a flat portion at the second end 114. Similarly, in order to facilitate locking the brush portion 120 and the second end 114 together, the second end 114 can include an opening 114A, preferably a through hole, and the opening or recess is particularly Figure 5 Complementary to the flat portion at the second end, the brush portion 120 itself has an end portion 121A comprising a complementary flat portion and an extension extending through the opening 114A. The applicator assembly is thus characterized by continuity between the stem 112 and the brush portion 120.

[0079] like Figure 4B As shown, the brush portion 120 extends from the second end 114 and includes a core 121 and a plurality of rows of bristles 122 extending from the core 121. The core 121 has an end 121A that is complementary in shape to the second end 114. It should be noted that in the configuration of this first embodiment, the brush portion includes an arcuate portion 123 and an extended portion 124, each of which includes a row of bristles 122. Of course, this configuration of the brush portion 120 is shown merely as a non-limiting example.

[0080] In the context of the present invention, the shaft / cap element 110 and the brush portion 120 are respectively made of a first polymer material and a second polymer material 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 the class 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 materials can be polymer materials at least partially produced from biomass or from a post-consumer recycled plastic (PCR) source, or even a blend of materials made partially from biomass and partially from a PCR source. It should also be noted that if both the first and second materials are composed of only one polymer, it is of course contemplated that one or both of the first and second materials may include one or more minor components, such as fillers, to supplement the primary polymer or polymers, without departing from the scope of the present invention. Such minor component(s) can be preferably selected so as not to interfere with the recycling of the first and second materials.

[0081] Of course, in the context of the present invention, if the stem / cap element 110 and the brush 120 must be made of a polymer material that is compatible with recycling, then the other elements of the dispensing device 1 are preferably made of materials with the same compatibility. This eliminates the need to separate these elements when recycling the dispensing device 1. Thus, according to one possibility of the present invention, the stem / cap element 110, the bottle 20, and the cap 30 can all be made of a first material, or a material of the same type as the first material (in the case of the bottle 20 and the cap 30), and the brush 120 and the scraper 40 can be made of a second material, or a material of the same type as the second material (in the case of the scraper 40).

[0082] According to the principles of the present invention, in particular Figure 3A and Figure 3B The applicator assembly 10 depicted in FIG. 1 can be manufactured by a manufacturing method comprising the following steps: - The stem / cap element 110 and the brush portion 120 are formed using a dual-material manufacturing technology. The stem / cap element 110 includes a skirt 111 adapted to cooperate with the neck 210 of the bottle 20 and a stem 112 extending from the skirt 111 and having a second end opposite to the skirt 111. The second end 114 and the brush portion 120 are integrally formed. The brush portion 20 includes a core 21 and at least one first row of bristles 122 extending from the core 112.

[0083] Figure 6A and Figure 6B (especially Figure 6B ) depicts an applicator assembly 10 according to a second embodiment, wherein the stem 112 includes an extension 116 at its second end 114, the extension 116 extending in line with the remainder of the stem 112 and including a row of bristles 118. Thus, the applicator assembly 10 according to this second embodiment differs from the applicator assembly 10 according to the first embodiment in that the stem 112 includes the extension 116 at its second end 114.

[0084] like Figures 6A to 6C As shown, in this second embodiment, second end 114 includes an extension 116 that extends over most of the length of brush portion 120. Extension 116 is housed within core 121, except for the portion where its bristles protrude from core 121. The comb portion formed by rows of bristles 118 assists in the application of cosmetic product and provides greater rigidity than the bristles 122 of the brush portion. This allows a user of cosmetic product dispensing device 1 to utilize both types of comb portions, depending on the type of cosmetic product application desired.

[0085] Likewise, the extension 116 provides significant stiffness to the brush portion 120 because a majority of the volume of the core is occupied by the extension 116. Figure 7A As shown, in order to provide the brush portion 120 with such rigidity while facilitating good locking of the brush portion and the second end 114, the second end 114 has a first cross-section that is smaller from the rest of the rod body 112 in a direction away from the skirt 111. The first cross-section includes an opening 114A and a flat portion. The flat portion is extended by a circular second cross-section forming the extension portion 116. The second cross-section includes a row of bristles 118. Figure 7B As shown, this rounded shape of the second cross-section provides good rigidity despite the combination of the wiper portion 120 and the second end being tapered in a direction away from the skirt portion 118 .

[0086] The manufacturing method of the applicator assembly 10 according to the second embodiment differs from the manufacturing method of the applicator assembly 10 according to the first embodiment in that, in the step of forming the stem / cap element 110 and the brush portion 120 , the formed stem / cap element 110 includes an extension portion 116 .

[0087] Figures 8A to 8C An applicator assembly 10 according to a third embodiment is depicted, which comprises a tensioner 117 housed in a core 121 of a brush portion 120 at the second end of the stem / cap element 110. The applicator assembly 10 according to this third embodiment differs from the applicator assembly 10 according to the first embodiment in that it comprises a tensioner 117 housed in a core 121 of the brush portion 120 at the second end of the stem / cap element 110.

[0088] In the above and the rest of this document, the tensioner refers to an element of the rod 110 that is configured to control the flexibility / rigidity of the brush portion, i.e., to generate tension / rigidity of the brush portion. Thus, such a tensioner is intended to be housed in the core 121 of the brush portion 120 to provide a frame for the brush portion 120, rather than occupying most of the volume of the core as in the case of the extension 116 according to the second embodiment. Figure 8C As shown, the tensioner 117 according to the present invention generally has an area in the transverse cross section of the brush portion 120 that is less than half or even one third of the area of ​​the core 121 .

[0089] In this third embodiment, if Figure 9A and Figure 9B As depicted, the stem 112 is extended at its second end 114 by a tensioner 117. Aside from the presence of the tensioner 117, the second end 114 has a similar configuration to the second end 114 of the applicator assembly according to the first embodiment. Figure 8B As shown, the tensioner 117 extends over most of the length of the brush portion 120, here approximately three quarters of its length. Figure 10A and Figure 10BThis extension of the tensioner 117 , as seen and discussed in the context of the depicted variations of the present embodiment, is shown by way of example only and may vary depending on the desired stiffness characteristics of the brush portion 120 .

[0090] The tensioner 117 has a substantially semicircular cross-section. In this embodiment, the diameter of the semicircular cross-section of the tensioner 117 is less than half the diameter of the rod 111 between the two ends 114. With this diameter, the tensioner 117 is Figure 9A The height shown is less than one-quarter of the diameter of the shaft 111 between the two ends 114. These values ​​are, of course, given only as examples. Generally speaking, the transverse dimension of the tensioner 117, excluding any reinforcement, is between 5% and 60% of the maximum transverse dimension of the rest of the shaft, or even between 10% and 50% or 20% and 40%.

[0091] Likewise, while the tensioner 117 advantageously has a circular cross-section, such as a substantially semicircular shape, as in the present embodiment, it is also conceivable that the tensioner 117 has some other cross-section without departing from the scope of the present invention. It is also shown in subsequent embodiments that while the tensioner 117 in the present embodiment has a constant transverse cross-section over its entire length, it is entirely conceivable that the tensioner 117 has a cross-section that varies along its length depending on the stiffness characteristics required of the brush portion 120.

[0092] The manufacturing method of the applicator assembly 10 according to the third embodiment differs from the manufacturing method of the applicator assembly 10 according to the first embodiment in that, in the step of forming the stem / cap element 110 and the brush 120 , the formed stem / cap element 110 includes a tensioner 117 .

[0093] Figure 10A and Figure 10B An applicator assembly 10 according to a variation of the third embodiment is depicted, in which the tensioner 117 has a shortened length. Thus, in this variation, the tensioner extends over a length that is approximately one-third the length of the brush portion 120. In the context of the present invention, the brush portion 120 thus has a lower stiffness than the brush portion 120 according to the third embodiment.

[0094] According to the present invention, the tensioner 117 may have a length between the length of the brush portion 120 and zero length, ie, it may have the configuration of the first embodiment in which the tensioner 117 is not provided.

[0095] Therefore, in this embodiment, it is entirely conceivable to use a design and manufacturing method of an applicator assembly comprising the following steps: - determine the required stiffness of the brush, - determining the length of the tensioner 117 corresponding to said desired stiffness, - Manufacturing an applicator assembly 10 comprising a tensioner 117 having a tensioner length thus determined, using the manufacturing method of an applicator element according to the third embodiment.

[0096] In this way, the stiffness of the brush portion 120 may be adjusted according to the characteristics desired to optimize the application of the cosmetic product.

[0097] according to Figure 11A and Figure 11B In the fourth embodiment shown, the tensioner 117 may include a reinforcement 117A to provide increased rigidity in a particular direction, such as the direction of the brush portion including the rows of bristles. Thus, the applicator assembly 10 according to this embodiment differs from the applicator assembly 10 according to the third embodiment in that the tensioner includes the reinforcement 117A.

[0098] Therefore, in Figure 11B As can be seen in the figure, tensioner 117 has a reinforcement 117A at its lower portion, in the form of a wall extending from the remainder of tensioner 117 (i.e., the semicircular cross-sectional body of the tensioner). In this embodiment, reinforcement 117A provides increased rigidity in the direction of wall extension while maintaining relative flexibility in directions perpendicular to this extension. In this embodiment, reinforcement 117A extends from the body of tensioner 117 to a height approximately equal to one-third of the diameter of tensioner 117 (i.e., the diameter of the semicircle forming its transverse cross-section). This value is provided merely as an example, and reinforcement 117A may extend to a different height without departing from the scope of the present invention. Thus, for example, this height may range from 10% to 50% of the diameter of tensioner 117, or even from 20% to 40% of this diameter. In this embodiment, the width of reinforcement 117A is approximately equal to one-sixth of the diameter of tensioner 117 (i.e., the diameter of the semicircle forming its transverse cross-section). Of course, other values ​​are conceivable without departing from the scope of the invention.

[0099] Likewise, while the reinforcement 117A extends the entire length of the tensioner 117 in this embodiment, it is likewise contemplated that the reinforcement 117A extends only a portion of the length of the tensioner 117 without departing from the scope of the present invention.

[0100] Note also that this reinforcement can reduce the thickness of the core 121 at the reinforcement 117A, thereby limiting the influence of the core 121 on the row of bristles 122 formed facing the reinforcement 117A. The row of bristles 122 formed in this way facing the reinforcement 117A has a higher hardness than the row of bristles in which the core thickness is not reduced.

[0101] The applicator assembly 10 according to this fourth embodiment can be manufactured by a manufacturing method different from that of the applicator assembly 10 according to the third embodiment, except that, in the step of forming the stem / cap element 110 and the brush portion 120 , the tensioner 117 includes a reinforcing portion 117A.

[0102] Figure 12A and Figure 12B The stem / cap element 110 of the applicator assembly 10 according to the fifth embodiment is depicted, wherein the tensioner 117 includes two reinforcing portions 117A, 117B extending radially away from each other. Thus, the applicator assembly 10 according to this fifth embodiment differs from the applicator assembly 10 according to the fourth embodiment in that the tensioner 117 includes a second reinforcing portion 117B extending radially away from the reinforcing portion 117A (which becomes the first reinforcing portion 117A).

[0103] Thus, in this fifth embodiment, to provide particularly asymmetric stiffness, first and second reinforcements 117A, 117B can be positioned in line with one another around the body of the tensioner 117. In this fifth embodiment, the second reinforcement 117B extends to a height that is approximately twice the height of the first portion 117A. This dual extension height is particularly permissible in this fifth embodiment because the second reinforcement extends from a transverse cross-section of a semicircle of the tensioner 117. Of course, depending on the geometry of the tensioner 117 and the orientation of the first and second reinforcements 117A, 117B, the height ratio of the first and second reinforcements can vary, so the second reinforcement 117B can have the following extension heights without departing from the scope of the present invention:

[0104] - between the extended height of the first portion 117A and three times that height, or even between 1.5 times or 2.5 times the extended height of the first portion 117A, - or between starting from and reaching a quarter of the extended height of the first portion 117A, or even between a third and two thirds of the extended height of the first portion 117A.

[0105] The application assembly 10 according to the fifth embodiment can be manufactured by a manufacturing method of the applicator assembly 10 different from the manufacturing method of the fourth embodiment, the difference being that, in the step of forming the rod body / cap element 110 and the brush portion 120, the tensioner 117 includes first and second reinforcement portions 117A, 117B.

[0106] 13A to 13CThe cap / stem element 110 of the applicator assembly 10 according to the sixth embodiment is depicted, wherein the tensioner 117 comprises first and second reinforcing portions 117A, 117B extending radially at 120° to each other. The applicator assembly 10 according to this sixth embodiment differs from the applicator assembly 10 according to the fifth embodiment in that the first and second reinforcing portions 117A, 117B extend radially at 120° from the circular portion of the tensioner 117 and have the same dimensions.

[0107] The arrangement of the first and second reinforcement portions 110 with such a tensioner 117 configuration provides good rigidity in both extension directions of the first and second reinforcement portions 117A, 117B.

[0108] The applicator assembly 10 according to this sixth embodiment can be manufactured using a manufacturing method different from the manufacturing method of the applicator assembly 10 according to the fifth embodiment, the difference being that, in the step of forming the stem / cap element 110 and the brush portion 120, the first and second reinforcement portions 117A, 117B extend radially at 120° from the circular portion of the tensioner 117.

[0109] 14A to 14C An applicator assembly 10 according to a seventh embodiment is depicted, in which the tensioner 117 comprises three reinforcements 117A, 117B, 117C arranged at 120° to one another, wherein the extension height of one reinforcement 117C varies along the longitudinal direction of the stem / cap element 110. The applicator assembly 10 according to this seventh embodiment differs from the applicator assembly 10 according to the sixth embodiment in that a third reinforcement 117C is present, arranged at 120° to the first and second reinforcements, and has an extension height that varies along the tensioner 117.

[0110] In fact, in 15A to 15D As can be seen in the figure, the extended height of the third reinforcement 117C varies along the tensioner from zero height to a maximum height that is approximately equal to the height of the first and second reinforcements 117A and 117B. This varying extended height of the reinforcement 117C allows the thickness of the core 121 of the brush portion 120 to vary at the row of bristles 122 facing the reinforcement 117C. This results in the perceived stiffness of the bristles 122 varying along that row, with bristles 122 with a smaller core 121 thickness (maximum extended height) having less freedom to press down and thus feeling more stiff than bristles with a thicker core 121 thickness (and therefore the greatest freedom to press down).

[0111] It should be noted that the first and second reinforcements 117A, 117B have a maximum height over the entire length of the tensioner 117, and the rows of bristles 122 facing these two reinforcements 117A, 117B produce a feeling of increased hardness for the same reason as the bristles 122 of the brush portion offset from the reinforcements 117A, 117B, 117C.

[0112] The applicator assembly 10 according to this seventh embodiment can be manufactured by a manufacturing method different from the manufacturing method of the applicator assembly 10 according to the sixth embodiment, except that, in the step of forming the stem / cap element 110 and the brush portion 120, the tensioner 117 includes the first, second and third reinforcement portions 117A, 117B, 117C associated with the seventh embodiment.

[0113] Figure 16A and Figure 16B The stem / cap element 10 of an applicator assembly 110 according to a variation of the seventh embodiment is depicted, wherein the first and second portions 117A, 117B each include three through-holes (not labeled with reference numerals). Thus, the applicator assembly 110 according to this variation of the seventh embodiment differs from the applicator assembly 110 according to the seventh embodiment only in that the first and second reinforcement portions 117A, 117B include the through-holes.

[0114] Such through-holes make it possible to facilitate the locking of the brush portion 122 on the first and second parts 114 of the shaft / cover element 110. Of course, it should be noted that in the context of the present invention and in all described embodiments comprising a tensioner 117 comprising one or more reinforcements 117, 117A, 117B, 117C, it is entirely conceivable that some or all of these reinforcements 117, 117A, 117B, 117C comprise one or more through-holes.

[0115] The applicator assembly 10 according to the variation of the seventh embodiment can be manufactured using a manufacturing method different from the manufacturing method of the applicator assembly 10 according to the seventh embodiment, the difference being that, in the step of forming the stem / cap element 110 and the brush portion 120, the first and second reinforcement portions 117A, 117B each include three through holes.

[0116] 17A to 17D An applicator assembly 10 according to an eighth embodiment is depicted, wherein the tensioner 117 includes three reinforcements 117A, 117B, 117C arranged at 120° relative to one another, one reinforcement 117C including a row of bristles extending from corresponding bristles of the brush portion. The applicator assembly 10 according to this eighth embodiment differs from the applicator assembly 10 according to the seventh embodiment in that the third reinforcement 117C has a constant extension height and includes a row of bristles 122 forming a comb portion.

[0117] In a configuration similar to that of the extension 116 described in the context of the second embodiment, at least one reinforcement 117C may thus comprise a row of bristles 118. Figure 17D As shown, in this ninth embodiment, the brush portion 120 itself comprises a row of bristles 122 extending from the bristles of the third reinforcement portion. Thus, the brush portion 120 comprises some "mixed bristles" whose core is reinforced by the bristles 118 of the third reinforcement portion 117C.

[0118] Likewise, Figure 17D As shown, the brush portion 120 further includes two rows of bristles having an increased sense of hardness at locations facing the first and second reinforcement portions 117A, 117B.

[0119] The applicator assembly 10 according to this ninth embodiment can be manufactured using a manufacturing method that is different from the manufacturing method of the applicator 10 according to the eighth embodiment, the difference being that, in the steps of forming the stem / cap element 110 and the brush portion 120, the third portion has a constant extension height and includes bristles 118, and the brush portion includes a row of bristles 122 that includes "mixed" bristles as described above.

[0120] Figure 19 The applicator assembly 10 according to a variation of the ninth embodiment is depicted in an enlarged cross-sectional view of the brush portion 120, wherein the brush portion 120 includes alternating conventional bristles 122 in the rows of bristles 122 from which the bristles of the third reinforcing portion 117C extend. Therefore, the applicator assembly 10 according to this variation differs from the applicator assembly 10 according to the ninth embodiment only in the presence of such alternating conventional bristles 122 in the rows.

[0121] like Figure 19 As shown, the rows of bristles 122 of the brush portion at the third extension 117C include alternating hybrid bristles 122 (i.e., bristles whose cores are reinforced by the bristles 118 of the third extension 117C) and traditional bristles 122 (i.e., bristles that do not receive the bristles 118 of the third reinforcement 117C).

[0122] The applicator assembly 10 according to the variation of the ninth embodiment can be manufactured using a manufacturing method different from the manufacturing method of the applicator assembly 10 according to the ninth embodiment, except that, in the step of forming the stem / cap element 110 and the brush portion 120, the brush portion 120 includes alternating conventional bristles 122 at the rows of bristles 122 from which the bristles of the third reinforcement portion 117C extend.

[0123] Figure 20A and Figure 20BThe applicator assembly 10 according to the tenth embodiment is depicted, wherein the tensioner 117 includes three reinforcements 117A, 117B, 117C that are 120° apart from each other, and each of the three reinforcements 117A, 117B, 117C includes a row of bristles 118 extending therefrom. The applicator assembly 10 according to the tenth embodiment differs from the applicator assembly 10 according to the ninth embodiment in that the first and second reinforcements 117A, 117B also include respective rows of bristles 118 extending therefrom.

[0124] In fact, in Figure 20B As can be seen in the figure, in this tenth embodiment, the bristles 118 of the first and second reinforcing portions 117A, 117B have a configuration similar to the bristles 118 of the third reinforcing portion 117C described in the context of the ninth embodiment. Thus, as described above with reference to the ninth embodiment, the brush portion 120 includes a corresponding row of bristles 122 for each row of bristles of the first, second, and third reinforcing portions 117A, 117B, 117C, from which the bristles extend. Thus, the brush portion 120 includes "mixed bristles" for each reinforcing portion 117A, 177B, 117C, the core of which is reinforced by the bristles 118 of these reinforcing portions 117A, 177B, 117C.

[0125] The applicator assembly 10 according to this tenth embodiment can be manufactured using a manufacturing method different from the manufacturing method according to the ninth embodiment, the difference being that, in the steps of forming the stem / cap element 110 and the brush portion 120, each of the first, second and third reinforcements 117A, 117B, 117C includes bristles 118, and the brush portion 120 includes "mixed bristles" whose core is reinforced by the bristles 118 of these reinforcements 117A, 177B, 117C due to each reinforcement 117A, 177B, 117C.

[0126] 22A to 22D An applicator assembly 10 according to an eleventh embodiment is depicted, in which the tensioner 117 includes a row of bristles extending through the brush core. Thus, the applicator assembly 10 according to this eleventh embodiment differs from the applicator assembly 10 according to the ninth embodiment in that the first and second reinforcements 117A, 117B have a reduced extension height, and the brush portion 120 does not include a row of bristles 122 facing the third reinforcement 117C, the bristles of the reinforcement row protruding from the core 121.

[0127] In this eleventh embodiment, according to a possibility similar to that of the extension 11 described in the context of the second embodiment, the bristles 118 thus protrude from the core 121 and are therefore intended to participate directly in dispensing the cosmetic product. As already described in the context of the second embodiment, the applicator assembly thus comprises two types of bristles 118, 122, bristles of high hardness associated with the first material and bristles that are flexible due to the use of the second material. The arrangement of the bristles 118 at the third reinforcement 117C is Figures 23A to 23C Shown in.

[0128] The applicator assembly 10 according to this eleventh embodiment can be manufactured using a manufacturing method different from the manufacturing method according to the ninth embodiment, the difference being that, in the steps of forming the stem / cap element 110 and the brush portion 120, each of the first and second reinforcements 117A, 117B has a reduced extension height, and the brush portion 120 does not include bristles 122 at the third reinforcement 117C, and the bristles 118 of the third reinforcement 117C protrude through the core 121 of the brush portion 120.

[0129] 24A to 24D The applicator assembly 10 according to the twelfth embodiment is depicted, wherein one end of the tensioner 117 includes bristles 118E. The applicator assembly 10 according to the twelfth embodiment differs from the applicator assembly 10 according to the fifth embodiment in that one end of the tensioner includes bristles 118E.

[0130] like 25A to 25D As shown, in this twelfth embodiment, the tensioner 117 has bristles 118E extending therefrom at its end opposite the skirt 111. It should be noted that in this twelfth embodiment, the bristles 118E are arranged in a plane defined by a truncation of a semicircle in the transverse cross-section of the tensioner 117. Five bristles 118E are distributed at regular angular intervals.

[0131] The applicator assembly 10 according to this twelfth embodiment can be manufactured using a manufacturing method different from that according to the fifth embodiment, in that, in the step of forming the stem / cap element 110 and the brush 120 , the tensioner 117 includes bristles 118E at its end.

[0132] 26A to 26D The applicator assembly 10 according to the thirteenth embodiment is depicted, in which the tensioner 116 has bristles 118E extending in a three-dimensional distribution at its end opposite the skirt 111. The applicator assembly 10 according to the thirteenth embodiment differs from the applicator assembly 10 according to the twelfth embodiment in that the bristles 118E at the end of the tensioner have a three-dimensional distribution.

[0133] In fact, in 27A to 27D In, especially in Figure 27C As can be seen in FIG, the bristles are aligned with the rest of the tensioner and extend in an extended manner, ie in a three-dimensional distribution.

[0134] The applicator assembly 10 according to the thirteenth embodiment can be manufactured using a manufacturing method different from the manufacturing method according to the twelfth embodiment, the difference being that, in the step of forming the stem / cap element 110 and the brush portion 120, the tensioner 117 has bristles 118E distributed in three dimensions at its end.

[0135] Of course, as shown in the various embodiments starting from the eighth embodiment, if the tensioner 117 can equally well provide support for the bristles 118, 118E and for the rigid bristles associated with the bristles 122 of the brush portion 120 as supplementary bristles for applying cosmetic products, then the tensioner 117 according to the present invention can also provide support for other elements of the brush portion 120, such as the arcuate portion 119 or the comb portion provided by the second reinforcement portion 117B, as described below with reference to Figures 28 to 29. Figure 31C described.

[0136] therefore, Figures 28A to 28C An applicator assembly 10 according to a fourteenth embodiment of the present invention is depicted, wherein the tensioner 117 includes an arcuate portion 119 having a row of bristles 118. The applicator assembly 10 according to this fourteenth embodiment differs from the applicator assembly 10 according to the fifth embodiment in that the tensioner 117 includes the arcuate portion 119 in addition to the first and second reinforcing portions 117A, 117B.

[0137] like Figure 28B and Figure 28C As shown, the arcuate portion 119 extends along a curve between the two ends (not labeled with reference numerals) of the brush portion 120, starting from the rest of the tensioner 117 (i.e., the main body of the tensioner 117), which is made of the first material. Figure 28C and Figure 29C As can be seen in FIG, the arc portion 119 extends toward the second reinforcement portion 117B. Figure 29A and Figure 29B As shown, the arcuate portion includes a row of bristles 118 that is opposite the rest of the tensioner 117 (i.e., the main body of the tensioner 117). Because they are made of the first material, the row of bristles 118 on the arcuate portion generally has a higher stiffness than the bristles 122 of the brush portion. It should be noted that the arcuate portion 119 and the bristles 118 included therein have a configuration similar to that taught in US2019014895A1.

[0138] The applicator assembly 10 according to the fourteenth embodiment can be manufactured using a manufacturing method different from the manufacturing method of the applicator assembly 10 according to the fifth embodiment, the difference being that, in the step of forming the stem / cap element 110 and the brush portion 120, the tensioner 117 includes the arcuate portion 119 according to the fourteenth embodiment.

[0139] Figures 30A to 30C The applicator assembly 10 according to the fifteenth embodiment of the present invention is depicted, in which the tensioner 117 includes a comb portion (not designated by a reference numeral) in the second reinforcing portion 117B provided by a recess (not designated by a reference numeral) in the second reinforcing portion 117B. The applicator assembly 10 according to this 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 portion 120 and includes a recess at least at the height portion thereof protruding from the core 121, such that the second reinforcing portion 117B includes the comb portion protruding from the core 121.

[0140] exist Figures 31A to 31C As can be seen in the figure, the height of the second reinforcement 117B relative to the rest of the tensioner 117 (i.e., the tensioner body) decreases in the direction from the skirt 111 to the second end 114. The recesses are regularly distributed throughout the length of the second reinforcement 117B and form a constant depth in the reinforcement 117B. Thus, the portion of the second reinforcement 117B that protrudes from the core 121 forms a comb portion that conforms to the overall frustoconical shape of the brush portion 120 according to this fifteenth embodiment.

[0141] Of course, this shape and recess of the second reinforcement 117B are shown only as examples, and therefore it is entirely conceivable that the second reinforcement 117B has a constant extension height over the entire length of the tensioner, or that the recess has alternating first and second depths, without departing from the scope of the present invention.
