Definitions

• the invention relates to an applicator for a cosmetic product and an associated applicator assembly.
• Cosmetic product applicator assemblies are known, in particular for a cosmetic product intended to be applied to eyelashes such as mascara, comprising a container containing the cosmetic product and an applicator adapted to be removably attached to the container.
• the container generally comprises a body, the body comprising walls defining a reservoir in which the cosmetic product is contained, and a neck defining an opening through which the cosmetic product can be extracted.
• the applicator assembly generally includes a cap adapted to be attached to the neck, a stem extending from the plug and an applicator attached to a free end of the stem.
• the applicator comprises a core and a plurality of protuberances or bristles extending from the core.
• the rod and the applicator extend inside the tank.
• the applicator is immersed in the cosmetic product contained in the reservoir.
• the user detaches the neck cap and extracts the applicator from the container.
• the container generally comprises a wiper, fixed inside the neck.
• the applicator slides inside the wiper. The wiper scrapes the cosmetic product in excess on the stem and the applicator.
• the wiper thus makes it possible to regulate the quantity of product present on the applicator and avoids an excessive application of cosmetic product on the eyelashes.
• the wiper limits, in particular, the amount of product present on the protuberances.
• Two parameters interact for this purpose.
• radial extension of a protuberance is meant the distance between the longitudinal axis of extension of the core and the free end of the protuberance.
• zones having protuberances of lower radial extension favor the loading of the applicator while the zones having protuberances of longer radial extension favor the combing of the eyelashes.
• the applicators comprising protuberances intended to reinforce the combing effect of the eyelashes are today used with large diameter cores.
• the associated wiper then has a large diameter and, consequently, the receptacle intended to receive it too. Therefore, the associated applicator assembly has an external diameter too high compared to the desired aesthetics for this type of product.
• An object of the present invention is to provide an applicator which comprises protrusions allowing a combing effect of the eyelashes, which has a sufficiently rigid core and which does not induce the use of too bulky containers.
• the invention relates to an applicator for a cosmetic product comprising a core having a first end, said proximal end, and a second free end, said distal end, and a plurality of protuberances projecting from the core, said protuberances being molded with the core.
• the core has a heart and ribs extending between its proximal end and its distal end, from the heart.
• the applicator of the invention solves the problem by proposing a soul which can be relatively thin while providing the expected rigidity for the function it has to fulfill, namely to support protrusions allowing a combing effect eyelashes without sagging when applying the cosmetic product to the eyelashes of a user.
• said protuberances are divided into different rows, oriented longitudinally,
• the core has a constant section from its proximal end to its distal end
• the ribs extend from the proximal end to the distal end of the core
• the ribs are parallel to an axis of the soul
• the ribs have a rounded section
• the core is made of plastic material
• the protuberances are made of plastic material
• the core and the protuberances are molded in the same material
• the heart is of substantially circular section
• the ribs are spaced radially around the periphery of the core at a constant angular distance
• said angular distance is in the range [0; 180 °], and preferably 90 °,
• the protuberances have a semicircular section
• the protuberances each have a flat surface
• the protuberances are positioned so that plane surfaces of two adjacent protuberances are oriented in the same direction of rotation
• the applicator forms a brush.
• the invention also relates to an applicator assembly for a cosmetic product, comprising a container comprising a body forming a reservoir intended to contain the cosmetic product, and an applicator as previously described, adapted to be fixed on the container, so that the applicator is housed inside the tank.
• FIG. 1 is a diagrammatic perspective view of an exemplary embodiment of an applicator according to the invention
• FIG. 2 is a view from above of the exemplary embodiment illustrated in FIG. 1;
• FIG. 3 is a sectional view along the axis A-A referenced in Figure 1.
• the invention relates to an applicator 10 for a cosmetic product comprising a core 12 having a first end, said proximal end 13, and a second free end, said distal end 16, and a plurality of protuberances 30 projecting from the end 12.
• the core 12 is further extended here by a sleeve 14 for fixing the applicator 10, extending from the proximal end 13 of the core 12.
• protuberances 30 are molded with the core 12.
• the protuberances 30 may be made of material with the core 12 or molded onto the core 12.
• the core 12 has a heart 1 1 and ribs 17. These ribs 17 extend from the heart 1 1 of the core 12, between the proximal end 13 and the end distal 15 of said core 12 (see Figure 1).
• the protuberances 30 preferably extend from the ribs 17 (see FIG. 2). They may also extend directly from the heart 1 1 of said core 12. In addition, the protuberances 30 are divided into different rows, oriented longitudinally.
• the protuberances 30 are arranged in a plurality of rows R1 - R12 extending in the extension direction of the core 12, marked X in Figure 1.
• the rows R1 -R12, visible in FIG. 2, are all parallel to an axis of the core 12, in particular its longitudinal extension axis X.
• the rows R1-R12 are spaced radially around the periphery of the core 12 at a constant angular distance. This angular distance may vary from one embodiment to another. In the embodiment illustrated here, the angular distance is 30 °. In other words, the rows R1-R12 are twelve in number.
• the ribs 17 are parallel to the longitudinal extension axis X of the core 12.
• Figures 2 and 3 show in detail these ribs 17.
• they have a rounded section.
• the cross section of said ribs 17 is substantially in the shape of omega ( ⁇ ).
• transverse section is meant any transverse section made in a plane orthogonal to the longitudinal axis X of the core 12.
• these ribs 17 are distributed around the core 1 1 of the core 12. More specifically, the ribs 17 are spaced radially around the periphery of the core 1 1 at a constant angular distance. In the example shown here, the angular distance is 90 °. In other words, said ribs 17 are four in number.
• the core 12 will then have a sufficient rigidity to its function thanks to the longitudinal ribs 17 regularly spaced around the core 1 1 of the core 12.
• a cross section of the core 1 1 has a substantially circular shape whose diameter d1 1 will be in the interval [0.5; 2.5mm], preferably equal to 1.5mm (see FIG. 3).
• This same cross section will have a maximum space occupied by the ribs 17 in the form of a circle of diameter d17 which will be in the range [1, 5; 3.5mm], preferably equal to 2.8mm.
• the ratio is between 0.4 and 0.7, d 1 and d 17 being measured in the same unit.
• the core has a constant section from its proximal end 13 to its distal end 16.
• the core 12 will be molded in plastic material, as the protuberances 30 which will preferably be molded with the same plastic as the core 12, or even the material of the core 12.
• the core 12 and the protuberances 30 may be molded from a material based on LDPE (low density polyethylene).
• LDPE low density polyethylene
• Other materials may still be used, namely ExxonMobil's "EXACT” material or Dupont's "HYTREL” material or a mixture of these materials. Soul 12 will be scheduled full. It is also possible, in another embodiment not illustrated, that the core 12 is hollow.
• the ribs 17 belonging to the core 12 will be molded during the same operation.
• the protuberances 30 may have a semicircular section. In this way, they preferably each have a flat surface (see FIG. 2). Said protrusions 30 are here positioned so that the flat surfaces of two adjacent protuberances are oriented in the same direction of rotation around the core 12. In addition, still to facilitate manufacturing operations, the protuberances 30 will preferably rectilinear and s Each of them will extend along a normal axis X of the core 12. It should be noted that the applicator 10 advantageously forms a brush.
• the invention also relates to an applicator assembly for a cosmetic product, comprising a container comprising a body forming a reservoir containing the cosmetic product, and an applicator as previously described, adapted to be fixed on the container, so that the applicator is housed inside the tank.
• Said applicator 10 is fixed, for example, to the end of a rod, itself attached to a cap advantageously screwed to the container.
• the sleeve 14 is located in the rod and the proximal end 13 of the core forms the visible proximal end of the applicator.
• the ribbed core according to the invention in particular cross-core, has the advantage of providing, at constant bulk, a rigidity greater than that of a cylindrical core.
• the container has a neck whose diameter, including the internal diameter, is limited. This prevents the use of large applicators and justifies the use of an applicator with a ribbed core, especially cross, because usually the stiffness is obtained by increasing the diameter of cylindrical cores, at the expense of the length of the radial extension of the protuberances. It should also be noted that alternative embodiments are of course possible.
• the applicator of the invention comprises a curved core.
