Definitions

  • the invention concerns a cosmetic applicator according to the generic term of claim 1 .
  • Cosmetic applicators are used to apply decorative and cosmetic products to the body, preferably to the face . Furthermore cosmetic applicators are often used to apply make-up such as mascara to the eyelashes , which is why this type of cosmetic applicator is often called a mascara brush due to its appearance .
  • the cosmetic applicator is usually dipped into mascara once and distributed on the lashes with a twisting motion .
  • These ef fects are usually achieved by tinting the eyelashes .
  • Such a conventional cosmetic applicator is usually designed to pick up and spread the mascara by means of its bristles and/or bristle discs . Due to the simple alignment of the bristles , the lashes are only pulled in one direction when the cosmetic applicator rotates . The lashes usually take their place in the bristleless spaces between the bristles and are guided by the rotary movement through the adj acent bristles , while at the same time the lashes are wetted with mascara . The eyelashes are thus pressed into the path created by the interaction of the bristles and the spaces between them and are pulled forward, i . e . lengthened, by the friction with the mascara .
  • the lashes are only pulled away from the eyelid orthogonally due to the arrangement of the bristles , which are usually only arranged orthogonally to the core of the applicator . This makes it - at least for non-experienced users - di f ficult to reproduce the actual growth direction of lashes , which limits the design possibilities .
  • the lashes stand out from the eyelid in only one direction in some areas , as they are pressed together in the bristle- free spaces between the bristles during the rotation . This means that the mascara is generally not ideally distributed and the result of the moistened lashes is not seldom perceived as suboptimal .
  • the obj ect of the invention is to speci fy means by which the lashes can be better separated and brought into a fan-like divergent position relative to one another .
  • the bristle trimming of the core has several bristle belts .
  • Each bristle belt consists of several bristles , which are arranged completely ( thus in whole or substantially completely) one behind the other along a belt line extending along the circumference of the core .
  • There is a completely bristle- free space between immediately adj acent belt lines which can also be called a " channel" .
  • the solution according to the invention is characteri zed by the fact that several directly adj acent belt lines have a di f ferent course . Furthermore channels are formed between these belt lines - usually obstacle- free - into which lashes can be inserted without any special ef forts . The channels also have a di f ferent course .
  • the cosmetic applicator in general is usally designed in such a way that there is at least a rolling angle range of - preferably at least 45 ° , better at least 90 ° and ideally at least approximately 180 ° - on the applicator, in which the following happens when the applicator is rolled : The channels continuously strive to the side , thus .
  • the channels are even designed in such a way that some of the channels extend to the proximal end and some of the channels extend to the distal end .
  • the lashes which are where the multiple belt lines have the smallest distance between each other, are pulled apart in the direction of the roll axis of the core when the cosmetic applicator is rotated around the roll axis of its core .
  • the roll axis lies , at least partially, preferably fully, inside the bristle-bearing core .
  • the eyelashes can thus be distributed in the channels between the respective bristle belts , j ust like with conventional cosmetic applicators .
  • the starting position for this is preferably the position in which the belt lines have the smallest distance from each other and thus in many cases form channels that are orthogonal to the roll axis when viewed in pro ection .
  • the lashes are separated during a rotational movement around the roll axis of the cosmetic applicator in such a way that the lashes are virtually pushed away from each other and are not forced onto a narrower path and thus further compressed, as is usually the case with conventional cosmetic applicators .
  • This results in an increased distance between the lashes which increases again, especially in the area of the lash tips .
  • bristle trimming describes the entirety of all bristles which are on the bristle-bearing core .
  • a “bristle belt” in the sense of the invention consists of a number of bristles which are arranged completely or substantially completely one behind the other along the circumference of the core .
  • the bristle belt can be clearly distinguished from a "bristle row” .
  • bristle row describes bristles which are located one behind the other in longitudinal direction on the outside of the core .
  • a bristle row always contains only one bristle of a bristle belt .
  • a “belt line” in the sense of the invention thus designates an imaginary line which is formed by the connecting lines of the foot points of the individual bristles of a bristle belt .
  • a belt line also runs along the circumference of the core .
  • a belt line does not necessarily have to be a circular line that lies in a single plane . Rather, there are also belt lines that are three-dimensional obj ects . Not according to the invention are j umping or unsteady, j agged lines , preferably also not those that change their direction locally with a radius of curvature of less than 0 . 4 mm .
  • the "bristle-bearing core” or j ust “ core” refers to the carrier part of the cosmetic applicator that is covered with bristles . In a broader sense , this includes the entire cosmetic applicator except the bristles . In a narrower sense , however, the " core” is only the part of the cosmetic applicator that is connected to the handle or the attachement shaft ( to which the handle is attached) of the cosmetic applicator . The core and the attachement shaft are preferably separated from each other by at least one shoulder .
  • the " roll axis" refers to the axis around which the entire cosmetic applicator rotates during the aforementioned rotational movement that must be performed for the intended use of the cosmetic applicator .
  • the roll axis is preferably the longitudinal axis of the handle or the attachement shaft of the cosmetic applicator, which is usually also the geometric center axis of the handle or the attachement shaft .
  • the core with its bristles therefore also rotates around this roll axis .
  • the roll axis does not necessarily have to be the geometric center axis of the core , which is generally referred to as the longitudinal axis L .
  • the cosmetic applicator is designed in such a way that the imaginary core cut surface , which is formed by a belt line and which is created when the core is thought to be cut by a hot wire that is guided along the belt line , along which bristles are arranged one behind the other, forms an imaginary swash plate . So a belt line running around the circumference creates a surface , which cuts the core in an individual way and is called " swash plate” . These swash plates perform a wobbling motion when the core rotates around its roll axis .
  • a " swash plate” in the sense of the invention also means , as mentioned above , an imaginary surface which is formed by a belt line . Since a belt line runs around the circumference of the core , the surface thus formed intersects the core in a way that is individual for each belt line .
  • the term “ swash plate” is chosen because this imaginary disk usually does not perform a uni form, radial rotational movement when rotating around the roll axis , but "wobbles" .
  • “Wobbling” here means the fact that the individual ( geometric ) local center axes of the respective swash plates are preferably not identical to the roll axis of the swash plates .
  • the roll axis of the swash plates is again the roll axis of the core and therefore the roll axis of the entire cosmetic applicator .
  • wobbling is thus caused by the angle and the distance of the center axis of the swash plates from the roll axis .
  • the wobbling is caused by the tilt angle of the center axes of the swash plates to the roll axis and is the dominant and decisive wobbling motion .
  • such swash plates are designed in a way that they are di f ferent and therefore individual . This of fers the possibility to individually design the course of the bristle- free spaces and above all to design them in such a way that these spaces narrow or preferably widen when the cosmetic applicator is rotated around the roll axis . This ensures that the lashes and especially their spreading to each other can be adj usted by the cosmetic applicator when used as intended, preferably so that the distance between the lashes increases .
  • the swash plates which are formed by the multiple belt lines , form two groups of swash plates .
  • One group of immediately adj acent swash plates which are tumbling in the direction of the distal end of the core when the core rotates around its roll axis and a second group of immediately adj acent swash plates , which are tumbling in the direction of the proximal end of the core when the core rotates around its roll axis .
  • the tilt angle of the swash plate ' s center axis has a di f ferent algebraic sign compared to the roll axis in the first group than in the second group of swash plates .
  • the "distal end" of the cosmetic applicator represents the end of the core facing away from the handle .
  • proximal end accordingly designates the end of the core facing the handle and thus the transition from the core to the handle or the attachment shaft .
  • these two groups of imaginary swash plates are separated by at least one imaginary disk whose belt line forms a swash plate whose center axis is parallel to the roll axis of the core or whose center axis has an angle with respect to the roll axis of the core that is at least a factor of three smaller than the tilt angle of all other center axes of the swash plates in respect to the roll axis of the core .
  • at least one swash plate is formed, whose center axis is preferably parallel and in any case less than 5 ° inclined to the roll axis .
  • at least one central swash plate is formed, while towards the distal and the proximal end, the tilt angles of the swashplates or their central axes line up at opposite tilt angles .
  • the imaginary swash plates can be characteri zed by at least one third, predominantly or all of them, that they preferably all or predominantly form a flat imaginary surface , which suits some manufacturing processes .
  • the cosmetic applicator is also designed in such a way that the imaginary swash plates all or predominantly form a curved imaginary surface .
  • center axis of the swashplate is now more di f ficult to define for a curved surface .
  • the center axis in this case represents the center axis of an equivalent flat surface .
  • a surface is preferably used, which is created when a purely flat surface intersects the core .
  • the constant tilt angle of this flat surface corresponds to the local tilt angle of the swash plate with respect to a vertical plane at the intersection of the swash plate with the roll axis .
  • Another preferred design is a cosmetic applicator with bristles whose longitudinal axis is completely straight . On the one hand, this is more appropriate for most manufacturing processes . On the other hand, straight bristles are the right shape for the maj ority of bristle rows in order to separate them .
  • a cosmetic applicator is designed in such a way that there are curved and/or kinked bristles in the area where the belt lines are the shortest apart . This ensures that the lashes can be separated and pulled apart constantly and at a constant angle - at least in intervals - when the cosmetic applicator is rotated .
  • kinked bristles are preferably designed in such a way that the bristles are kinked in the radially outer third or quarter .
  • the bristle-bearing core of the cosmetic applicator has a cambered design . This is defined by the area of a vertical cross-section through the core decreasing from the largest vertical cross-sectional area of the core towards both the distal and proximal ends of the core . This ensures that the bristles lying on the cambered side are spread even further apart due to the local curvature of the surface on which they stand .
  • the bristles used in cosmetic applicators are at least predominantly conical in shape . On the one hand, this leads to a good guidance of the lashes during the intended application and on the other hand it is advantageous for some manufacturing processes .
  • a cosmetic applicator also has at least one row of bristles composed of bristles whose longitudinal axes of the bristles are exactly or approximately parallel to each other and/or in which the distance between the longitudinal axes of the bristles is exactly or approximately identical and/or whose longitudinal axes of the bristles are exactly or approximately orthogonal to the roll axis .
  • a " row of bristles” is composed of bristles that are located one behind the other in the longitudinal direction on the outside of the core .
  • a bristle row always contains only one bristle of a bristle belt .
  • the row of bristles is lined up along an imaginary line , which runs approximately and/or exactly parallel to the roll axis .
  • a cosmetic applicator is preferably designed in such a way that the tilt angle of the center axis of the respective swash plate increases in amount relative to the roll axis with decreasing distance to both the distal and the proximal end of the core . This angle increases towards both the distal and the proximal end .
  • this increase in the angle of inclination in both directions is interrupted by a central separation disc, whose central axis is ideally parallel to the roll axis .
  • the already mentioned at least one swash plate is the best choice , i f its center axis is parallel to the roll axis of the core or i f its center axis has a tilt angle to the roll axis of the core which is smaller than the tilt angle of all other center axes of the swash plates to the roll axis of the core . From this swash plate to the distal as well as to the proximal end the tilt angle of the center axes of the respective swash plate increases preferentially .
  • a further preferred design is that with increasing vertical distance of the bristle rows to the at least one bristle row, which is composed of bristles whose longitudinal axes are parallel to each other and/or in which the distance from the longitudinal axis of the bristle is approximately identical and/or whose longitudinal axes are orthogonal to the roll axis , the distance of the bristle tips of bristles lying on a bristle row increases or at least remains the same .
  • the bristles prefer to spread further and further apart the greater the vertical distance to the row, which is preferably used as the starting position for starting the intended application . In this way a better separation of the lashes can be achieved .
  • the "vertical distance" in the sense of the invention is the distance of the imaginary connecting line of a bristle row to a reference line , whereby the imaginary line of the bristle row is proj ected onto the vertical plane in which the roll axis lies .
