Definitions

• the invention relates to cosmetic product applicators comprising looped protuberances.
• Articles for the application of mascara are known. These articles include an applicator in the form of a brush brush or an injection molded plastic brush. These brushes give good makeup results. However, we are always looking for improvements in this result and comfort of use for the user. Among the improvements, one can note the search for a better separation of the eyelashes, a better effect lengthening and / or curling eyelashes, or obtaining a mascara application as regular as possible on the eyelashes. It also seeks to reduce the frequency with which the user must plunge the mascara applicator into the mascara reservoir in order to recharge it.
• An object of the invention is therefore to improve the mascara applicators.
• a mascara applicator having a generally elongated shape defining a longitudinal axis and comprising protuberances, at least one of these protuberances forming a loop defining a through opening having a main axis of opening having a angle greater than 45 ° with a radial plane to the longitudinal axis of the applicator.
• the loops of the protuberances are loaded with mascara and form mini-reservoirs that are not emptied when the applicator leaves the reservoir, even if the latter comprises a wiper .
• These loops have an orientation conducive to contacting the eyelashes with the mascara they contain.
• the eyelashes are led through the loops for good coating by mascara without generating packets.
• the application movement transmitted by the user will cause the course of one or more eyelashes in at least a portion of the opening, the eyelash or lashes being loaded with mascara during this course. It is therefore a relatively large dose of mascara which is loaded onto the applicator at the outlet of the reservoir and then applied to the eyelashes.
• the volume of the opening of a protrusion forming a loop may be chosen to correspond to a predetermined amount of mascara to be applied to one or more eyelashes. This ensures that the right amount of mascara can be applied, for example to prevent the formation of packets.
• the fact that the opening has a volume capable of receiving a small number of eyelashes, for example a single eyelash allows to participate in the separation of the eyelashes and thus improve the makeup result.
• the protuberances in loops reduce the aggressive nature that may present the brush approaching an eye, and they reduce the apprehension that can feel the user when the brush is manipulated near the cornea.
• angle is greater than 60 0 , vdre greater than 70 0 , and preferably greater than 80 °.
• the main axis of the opening extends in a plane perpendicular to the longitudinal axis of the applicator.
• the opening has a generally elliptical shape.
• the opening and the outer contour of the protuberances have a generally elliptical shape.
• This shape allows to marry that of the eyelashes and thus improve the makeup result.
• the opening has edges forming a non-planar curve.
• This particular arrangement is likely to facilitate the contact of the eyelashes with the mascara worn by the loops, particularly if the user holds the applicator in an orientation that is not horizontal, for example at an angle.
• the opening has chamfered edges.
• the protuberance forming a loop has a generally non-rectilinear shape, preferably undulating, when the applicator is observed from a free end thereof.
• the applicator further comprises rectilinear protuberances.
• Such protuberances improves the display of mascara on the eyelashes to prevent the formation of packets thereon.
• These protuberances may for example extend in a radial plane relative to the longitudinal axis of the applicator.
• At least one protuberance comprises one or more secondary protuberances extending from it, preferably from its base.
• the presence of such protuberances has several advantages. First, they improve the spread of mascara on the eyelash, which avoids packets. Then, they also improve the separation of the eyelashes before or after they have been loaded with mascara.
• the protuberances forming a loop are at least three in number and form a row.
• the advantage of such a configuration is to allow a uniform application of mascara over a row of eyelashes.
• the protuberances of the row or at least one of the rows are all included in the same radial plane to the longitudinal axis of the applicator.
• This arrangement further improves the uniformity with which the mascara will be applied on a row of eyelashes.
• the applicator comprises several rows of protuberances forming a loop, these rows having between them a symmetry of revolution about the longitudinal axis of the applicator.
• the row or at least one of the rows of protuberances comprises only protuberances forming a loop.
• each protrusion loop of a row of looped protuberances is in contact with the protrusion which precedes and / or succeeds in the row.
• the applicator further comprises flaps, each flap being composed of at least:
• At least one second panel connected to a core of the applicator by the first panel and bearing the protuberances.
• a third panel can be used to connect the first and second panels.
• the first panel makes it possible to bind the second panel to the rest of the applicator. This connection can be done or not via a soul of the applicator.
• the first panels connect together the second panels of the shutters.
• the first panels, each linked to a second panel can all be linked together by one of their inner edge.
• the connection of these first panels forms the core of the applicator.
• the first panels have a generally parallelepipedal shape and the second panels have a generally slightly concave parallelepipedal shape.
• the first and second panels can obviously have other forms than these.
• the second panels may have a generally flat or undulating shape when they are observed from the free end of the applicator.
• the number of flaps can vary. It is thus possible to provide an applicator having at least one flap, or even at least two flaps, preferably at least three flaps.
• the panels may extend over a majority of the length of the applicator, preferably over its entire length. It is also possible that the panels can extend over a small part of the length of the applicator.
• the first panels of the different shutters are all of the same dimensions.
• the second panels of the different panels are all the same size.
• the first panel extends in a radial plane to the longitudinal axis of the applicator.
• the opening of at least one loop protrusion extends in the first panel.
• first and second panels of a flap form a cavity.
• this cavity is able to contain mascara after the applicator has emerged from a mascara reservoir.
• This cavity thus also forms a reserve of mascara when the applicator is out of the reservoir and thus reduces the number of times that the user is obliged to plunge the applicator back into the reservoir.
• the volume of this cavity depends in particular on the angle formed by these two panels. Preferably, this angle is less than 90 °, especially less than 75 ° or 60 °, preferably less than 45 °.
• the section of the cavity is not constant along the longitudinal axis of the applicator. Preferably, it is constant over a larger part of the cavity. More preferably, this section is constant on a median portion of the cavity and decreases at the ends thereof.
• the protuberances all extend from a face of the second panel opposite the cavity.
• protuberances on the second panel extend from this panel in a radial plane to the longitudinal axis of the applicator.
• the second panel has at least one row of protuberances forming a loop and at least one row of protuberances lacking a loop, that is to say solid, for example rectilinear.
• the second panel may have a row of protuberances forming a loop and two rows of solid protuberances.
• it has a row of protuberances forming a loop and three rows of solid protuberances.
• a row of protuberances forming a loop prefferably, it is possible for a row of protuberances forming a loop to be located on one edge of the panel and for the remainder of the panel to be occupied by at least one row of solid protuberances, or even at least two rows of rectilinear protuberances, preferably at least three rows of full protuberances.
• the second panel bears only protuberances forming a loop or that full protuberances.
• the applicator is in one piece.

• the applicator may be composed of a single material or of several different materials.
• the applicator is made by additive synthesis.
