Abstract

The device (1) has a core (2) from which applicator structures (6) extend away. The device is produced by a primary shaping process, with the applicator structures (5) extending along a longitudinal axis (L) of the core. The central axis (M) of the applicator structure (5) is formed with corrugation whose curvature changes and spans the central axis of the applicator structure completely in a plane.

Description

The invention relates to an applicator device according to the preamble of claim 1, an applicator comprising the applicator device and an application unit comprising the applicator device.

From the DE 60 2004 000 935 T2 For example, a cosmetic applicator is known which has bristles that can have a corrugation. This document relates to both nail varnish applicators, such as nail polish brush as well as on cosmetic applicators, such as mascara applicators. It is also known to produce these bristles together with a core of the applicator by way of injection molding. The aim of such an applicator is specified to make possible cosmetic products with different viscosities in a satisfactory manner orderable.

From the WO 97/28719 For example, there is known a combing apparatus for applying eyelashes makeup having curved bristles. These curved bristles are arranged in the form of a single row on the core of the applicator or in the form of exactly two provided opposite rows of bristles or rotationally symmetric bristles.

In this device is disadvantageous that due to the limited number of applicator elements often an insufficient amount of mascara fluid on the applicator for application to the eyelashes is available. Furthermore, when using such an applicator, the operator must always ensure that the applicator is at a favorable angle to the impacting eyelash. This means that the user often has to bring the applicator undesirably by rotation about the longitudinal axis of the applicator in a suitable position for applying mascara.

The object of the invention is to provide an applicator device which is suitable for forming a cosmetic applicator, in particular for applying mascara. In particular, the mass storage capacity for cosmetic composition should be improved and, despite a stripping process usually carried out when removing the cosmetic applicator from a mascara container, sufficient mascara mass should still remain on the applicator. The mascara mass should be distributed as evenly as possible on the applicator. In particular, it should be ensured that the mascara mass after the stripping process in a radially inner region, ie in an area near the core is kept, whereas free ends of the order organs should contain as precisely dosed Mascaramenge. In other words, it is therefore an object of the invention to provide a defined mascara reservoir in the region of the core of the applicator device.

Furthermore, the applicator device should be suitable for ensuring the widest possible all-round wetting of eyelashes with mascara and a curling effect by a clamping action of the eyelashes between applicators of the applicator device.

A further object of the invention is, in particular in a particular embodiment, to provide the all-round wetting of eyelashes with mascara composition in a particularly effective manner. A further object of the invention is to produce the applicator according to the invention in a particularly cost-effective and highly reproducible manner, in which high accuracies with regard to the bristle arrangement and the bristle shape are ensured.

Not least object of the invention to provide an aesthetically appealing in the unwetted state applicator, which has a certain spectacular appearance and a striking design.

Another object of the invention is to provide different application characteristics, e.g. To provide different degrees of separation or bundling effect and different pronounced separation and combing behavior of the applicator relative to the eyelashes available.

These objects are achieved with an applicator device having the features of claim 1. Advantageous embodiments are given in the dependent claims. Furthermore, these objects are achieved by an applicator device with the features of claim 21. Furthermore, these objects are achieved with a cosmetic unit having the features of claim 22.

The abovementioned objects are achieved with an applicator device, in particular for a mascara applicator, which has a core from which application organs radiate radially away. The applicator device is produced by means of a primary molding process, in particular integrally formed as a plastic part, and characterized in that at least partially the application organs in longitudinal extent along a longitudinal axis of the core are arranged in rows and have a central axis, the central axis of the application organs with at least one corrugation having a change in curvature and the central axis of an applicator member is completely in a plane or spans a plane.

Under a primary molding process in the context of the invention is to be understood the manufacture of a solid body of formless material. In accordance with DIN 8580, primary forming processes are all production processes in which a solid body is produced from an informal material. According to the invention, this includes all production methods from the field of plastic injection molding and in particular also a production method in the form of a 3D printing method in which an applicator device is produced by means of 3D printers from a shapeless mass. In particular, it does not relate to the primary molding process to manufacture an applicator device in the form of a built, i. composite Applikatoreinrichtung with a wire core and held by this prefabricated bristles. Furthermore, according to the invention, a brush production method is also not to be understood as a primary molding method in which prefabricated bristles are subsequently used in a prefabricated core.

Among the novel molding processes according to the invention are, in particular, one-, two- or multi-component injection molding processes Also to understand using various plastic raw materials. Applicator devices produced in this manner can be joined together with conventional assembly methods with additional components, for example an applicator rod or the like. In particular, an applicator device according to the invention, in which, for example, the core is hollow and on a support mandrel, which is made of a different material, attachable, glued or otherwise mountable.

In this case, it may be advantageous for the applicator device to be subdivided into at least two regions along its longitudinal direction, the regions differing either with regard to the geometries of the core of the applicator device or with respect to the applicator elements, be it in terms of their spatial form or arrangement or otherwise. Thus, according to a preferred embodiment of the invention, the applicator device comprises a first region with applicators or with a core of a first type and a second region with applicators or a core of a second type. As a result, it is possible in a simple manner to adapt various types of applicator to the needs of the operator by varying the core geometry as well as the order organ geometry or type in a wide range.

According to a particularly preferred embodiment, the central axes of application elements of a row are arranged in a common plane, wherein optionally the plane is arranged parallel to a longitudinal axis of the applicator device, in particular contains the longitudinal axis. Such an arrangement of corrugated application organs relative to the core of the applicator facilitates, in particular in the production process of the plastic injection molding, removal from the mold substantially.

According to a particularly preferred embodiment, viewed in the circumferential direction, the application elements arranged in the manner of a beam are distributed in such a way that in each case center axes of application elements of two rows lying opposite one another lie in a common plane.

In particular, for the generation of reservoir volumes for mascara mass can be provided that the corrugation of the central axes of application elements of adjacent rows is formed opposite.

A particularly uniform mass storage and order behavior is achieved if the corrugation of the central axes of the application organs of all corrugated application organs identical, i. is identical in terms of amplitude, wavelength, orientation and / or curvature. Thus, therefore, the entire Auftragorganbesatz the applicator or at least one of the areas of the applicator is constructed of identical application elements, which in particular guarantees a uniform distribution of mass storage and application properties over the area having such application elements. This is especially true when the corrugated application organs are all identical.

To form a tapered to the free (distal) end of the applicator applicator the core is tapered and formed in this case, the bristle of the first and second area, in particular the geometric spatial shape of the applicators be identical, since the conical design of the applicator is ensured to the free end by a taper of the core.

Conversely, it may of course also be useful for the conical design of the applicator to the distal end of the core in an end region of the applicator, e.g. in a second area identical to the first area, e.g. is cylindrical or continued, wherein in the second region an Auftragorganbesatz of a second type is present, which has no corrugation and in which decreases the radial longitudinal extension of the application organs away from the core to the distal end of the applicator.

Thus, in a simple manner in a cylindrical core by varying the length of the application organs (conical configuration) a decrease in the length of the applicators a result in the end to the free end tapered applicator can be provided. Ordering organs which become shorter at the free end also have a different bending characteristic and, in particular, have a somewhat less flexible design, so that positive effects also occur here as far as the separation and combing effect of the eyelashes is concerned.

In various embodiments of the invention, the application organs in the second region may be, for example, conical bristles, discs, disc sections, teeth or the like.

In particular for the wiping result on a scraper of a cosmetic / mascara unit, it has proved to be advantageous to arrange corrugated application organs in such a way relative to the core that free ends of the corrugated application organs point to the distal end of the applicator. Such an arrangement of the application organs facilitates in particular the stripping of mascara mass in the region of the free end of the application organs, since these are easy, in particular without themselves in the stripping to catch, let it pass through and bend well to the core.

Nevertheless, a considerable reservoir volume for mascara mass is achieved in the area of the foot or in the vicinity of the core of the application organs, in particular if they are somewhat thicker there, which is then available unchanged during application as well as after stripping.

A particularly high storage capacity with regard to the mascara mass adhering to the applicator is achieved if the application members of a first row are offset in the longitudinal direction of the applicator with respect to applicator members of adjacent rows. Particularly uniformly, this property can be formed distributed over the surface of the core, if they are arranged offset in such a way that the application elements of one row are arranged approximately centrally between the free gaps of second applicators another, adjacent row.

In order to form different applicators, the applicator device can be designed such that the application organs of the first region have a corrugation and the application organs of the second region are not corrugated but simply curved.

According to a further advantageous embodiment of the invention, the application organs are made of a different, in particular softer plastic than the core. This embodiment can be produced well in particular in the two-component injection molding process.

Preferred geometric dimensions of the applicator elements are characterized in that tangents are corrugated at central axes Order organs in the foot of the applicator member include an angle α to the longitudinal axis of the applicator, in particular, an angular range of 30 ° ≤ α <90 °, in particular 50 ° ≤ α ≤ 70 ° has proven.

• 0° ≤ β ≤ 90°, insbesondere 25° ≤ β ≤ 75° oder
• 0° ≤ β' ≤ 90°, insbesondere 25° ≤β' ≤ 75° oder
• α ‡ β oder α ‡ β'
• β < α oder β' < α.

Furthermore, in the case of corrugated application organs, it can be provided that tangents T at the point of inflection W of the central longitudinal axis L enclose an angle β or β 'with respect to the longitudinal axis L of the applicator, with the following being particularly preferred:

• 0 ° ≤ β ≤ 90 °, in particular 25 ° ≤ β ≤ 75 ° or
• 0 ° ≤ β '≤ 90 °, in particular 25 ° ≤β' ≤ 75 ° or
• α ‡ β or α ‡ β '
• β <α or β '<α.

Furthermore, it is advantageous that the application organs from the foot of the application organs towards the free end of the application organs are tapered, in particular tapered. As a result, a relatively stiff Auftragselementfußbereich can be achieved, which bends slightly during stripping and thus reservoir volume for mascara mass is provided sufficiently.

Of course, the applicators of the second type may be tapered bristles, teeth, discs, washers or disc segments or grooves.

In particular, in order to improve the all-round wetting of eyelashes, it may be advantageous for convex regions of the curved applicator elements to touch adjacent rows in a side view or at most to have a spacing which is smaller than a diameter of an eyelash to be acted upon by mascara. In that regard, a clamping effect is indeed spaced apart but in a side view almost touching order organs achieved and thus the eyelash is taken on both sides by order organs, so that a nearly complete 360 ° -Wennetzung can take place. Such a clamping effect causes by clamping gripping and clamping slipping along the application organs on the eyelashes also a desired curling effect, ie a bending forms of the eyelashes when applying the mascara mass.

If applicator elements are provided with convexly facing curved applicator sections, it is advisable to arrange the applicators of adjacent rows in the longitudinal direction of the applicator closer together than the applicators of adjacent rows, which face each other with their concavely curved sections. In this way, it is achieved that in each case two applicator elements of adjacent rows form a corresponding applicator element pair, which has convexly curved, mutually facing sections for improved wetting of the eyelashes with mascara.

The corresponding applicator member pairs are preferably arranged in rows in the circumferential direction around the core of the applicator, wherein an imaginary center plane between the respective corresponding applicator member forming application organs is preferably perpendicular to the longitudinal axis of the applicator. This ensures by a collection effect of the order organs of a Auftragorganpaares that a plurality of eyelashes is caught and thus can take place optimal bundling of the eyelashes.

This is ensured, in particular, by the fact that free ends of the applicator members forming an applicator member then expediently point in different directions with respect to the longitudinal axis of the applicator. This can for example be designed such that a free end of a first application member towards the distal end, whereas the second free end of the second applicator member points towards the handle of the applicator, ie to a proximal end of the applicator.

Likewise, the object of the invention is achieved by an applicator, in particular a cosmetic applicator having an applicator device according to the invention.

Likewise, the invention includes an applicator unit, in particular a cosmetic unit, which has an applicator device according to the invention. Such cosmetic units usually have a container for cosmetics, in particular for mascara mass, and a handle, which is on the one hand with the applicator in conjunction and on the other usually serves as a screw cap for the container. Furthermore, it is of course possible to provide a stripping device in the neck region of a container.

All in all, it is particularly advantageous in the invention that, on the one hand, visually appealing and spectacular-looking, flame-like applicators can be produced, which visually differ significantly from already known applicators and have a high value. On the other hand can be achieved by skillful arrangement of the application elements of the side area variable and tunable to the particular application applicator and in particular the wiping result can be positively influenced by corrugated trained and directionally arranged application organs. Furthermore, a high mascara mass loading of the applicator can be ensured since, at least in the foot regions of the application organs of an applicator according to the invention, there is much room for mascara mass which can be reliably held in reservoir volumes or reservoir regions.

the embodiment according to FIG. 7 in a longitudinal sectional view along the line AA FIG. 7 ,

A first embodiment of an applicator device 1 according to the invention is shown in FIG FIG. 1 shown. The applicator device 1 has a core 2 and a proximal end 3 and a distal end 4. The proximal end 3 is formed in a conventional manner for arranging the applicator device 1 on an applicator handle (not shown). At this applicator handle still sits a handling unit, such as a screw cap of a cosmetic unit (not shown). The distal end 4 is a free end. The core 3, as well as the applicator device 1 as a whole has a longitudinal axis L, which at least in the embodiment according to FIG. 1 is the axis of symmetry of the applicator device.

The applicator device 1 has a first region B ₁ with applicators 5 of a first type and a second region B ₂ with applicators 6 of a second type. The application members 5 of the first type are formed as corrugated bristles 5, which are explained in more detail below. The commission organs 6 of the second type are exemplified as substantially conically from the core 2 radially outgoing bristles formed.

The applicator 1 is integrally formed by means of a primary molding process, for example as an injection molded part or as a 3D printing part of the same plastic or in a two- or multi-component process of two or more different plastics, preferably the core 2 of a harder plastic and the Application organs 5, 6 are formed of a softer plastic. The core 2 is designed to be cylindrical throughout in the areas B ₁ and B _{2 in} order to make the applicator device 1 conically tapering towards the distal end 4, the application members 6 are made shorter and shorter at the free end, so that a cladding surface spanned by the application members 6 tapered conically towards the distal end 4. The application organs 6 are formed as straight bristles.

Of course, the core 2 may also have other geometric spatial forms. For example, in a modification of this embodiment, the core 2 may also have a crowned, i. concave convex outward space shape or a constricted, for example, concave inwardly extending spatial form. Furthermore, the core 2 can also be designed to be cylindrically stepped in sections, for example, along its longitudinal extent.

The corrugated application elements 5, hereinafter called corrugated bristles 5, each have a bristle foot 7 and a free bristle end 8. The application organs 5 are in the embodiment according to the FIG. 1 such that all free bristle ends 8 point in the direction of the distal end 4. The applicators 5 and the applicators 6 are each in rows R ₁ , R ₂ , R ₃ ... R _n along a longitudinal direction 100, which is aligned parallel to the longitudinal axis L, arranged. Seen in the circumferential direction U, the applicators 5 and 6 are also arranged in rows R _I , R _II , R _II ... R _XX . The application organs 5, 6 essentially radiate radially from the core 2. In the area of the bristle feet 7, two longitudinal directions 100 of adjacent bristles have a longitudinal spacing d between the bristle feet, wherein the distance d is in each case formed as an intersection point of a center axis M of an application member described below through an outer side of the core 2. The distance d is defined between longitudinally 100 two such puncture points.

The application organs 5, 6 of two adjacent rows R ₁ , and R ₂ are offset by the distance ½ d, arranged in the longitudinal direction 100.

It goes without saying that the above-described row-like arrangement does not necessarily have to be realized for both types of order organ 5, 6 on an applicator device. Thus, for example, only the application members 5 of the type 1 can be staggered in the longitudinal direction, whereas this does not necessarily apply to the order members of the second type 6 and vice versa.

The above-described arrangements of the application organs of type 1 and type 2 in rows in the longitudinal direction 100 as well as in the circumferential direction U are mutatis mutandis - although not described in detail later - applicable to the other embodiments.

Each of the applicator elements (bristles) 5 leaves the outside of the core 2 and inclined at an angle α to the free end 4. The angle α is in the FIGS. 1 ff. Pledged for reasons of simplification relative to the longitudinal axis L. The free ends 8 The bristles 5 are inclined at an angle γ against the outer side of the core 2 and against the longitudinal axis L and also have - as already described - towards the free end 4.

An axial length in the longitudinal direction 100 of the region B1 with an application organ set of application elements 5 of the first type is more than half the total length of the regions B1 and B2, which have a bristle facing. In particular, the axial longitudinal extent l _{1 of} the region B _{1 is} 50% to 70% of the total length of the applicator device 1, which has bristle stocking.

The area B ₂ extends over an axial longitudinal extent l ₂ , which is correspondingly smaller.

The bristles 5 are corrugated, i. they have a central axis M which has the curvature 0 in at least one point or in a region and this point is an inflection point or the region is a turning region up to which there is a curvature in a first direction and from which a curvature in a second direction , Under curvature in the context of the invention is also to be understood that around a turning point a piece of straight course of the central axis M may be present (turning area). Such a bristle course would then have the curvature 0. It is essential that in a corrugated bristles 5 according to the invention along the center axis M at least once the direction of curvature of the central axis M changes.

In addition, the bristles 5 are formed so wavy that the central axis M of a bristle 5 spans a plane, or lies in a plane. This means that each bristle 5 is two-dimensionally wavy, that is, the corrugation is arranged in a plane. This level E, which in the following FIG. 2 the sectional plane AA is, it runs preferably exactly However, this plane E (sectional plane AA) can also be aligned substantially parallel to the longitudinal axis L, wherein under substantially parallel to the invention an angular deflection of the plane E by an angle δ of up to +/- 10 ° to the longitudinal axis can take place. This means as a result that the central axis M is still in a plane, but this plane E inclined to the longitudinal direction 100 may be arranged so that the free ends 8 of the applicators 5 not directly to the free end 4 show, but under the Angle δ twisted at an angle.

Alternatively or additionally, the center axes M can at least partially extend beyond the plane E (AA) and thus to a lesser extent effect a three-dimensionally curved formation of the application organs 5, if and as far as this is possible in terms of manufacturing technology. The invention is thus expressly not limited to applicators 2 curved in two planes, but also includes three-dimensional curved corrugated applicators 5 within the limits of manufacturability. The production limits are in this case in particular produced by the injection molding process, with which the applicator devices are preferred. especially as regards the tool design of the injection molding tool set. It is particularly preferred to make all application elements 5 of the type 1 as similar as possible with respect to their order geometry, so that in the applicator device according to the invention with corrugated application elements 5, a flame-like and flickering appearance is created, which looks particularly spectacular. In particular, this optical impression can be assisted by the fact that, for example, a dark plastic, for example a black plastic, is used for the core, the application organs 5 optionally also including the applicator elements 6 made of red, yellow or black oranges, at least different colored plastic are formed. This spectacular optical impression comes into play, in particular, when the applicator device 1 of a mascara set is sold with applicator device 1 located outside the container and is clearly visible to the buyer, presented in a blister pack.

Furthermore, the applicators 5 as well as the applicators 6 preferably have a greater thickness in the region of the bristle foot 7 and taper towards the bristle end 8. The application organs 5, 6, in particular the application organs 5, may have a cross-section that is circular in any cross-section perpendicular to the central axis M, oval or else triangular or polygonal. Also conceivable is a polygonal cross-section with grooves, grooves or the like along the course of an applicator member 5, 6 in the outer region.

Based on Figures 2 . 2a Now an order organ 5 having a corrugation is described in detail. The longitudinal direction 100 is shown in these figures as a double arrow direction in order to make it clear that angle specifications for the angles α, β, δ also apply accordingly to arrangements of the application members in a position rotated by 180 ° on the core 2. The applicator 5 according to the FIG. 2 is in a sectional plane E along the line AA FIG. 1 shown enlarged. The application member 5 is in the region of the bristle foot 7 at the angle α from a top 9 of the core 2 from. In the embodiment according to the FIG. 2 For simplicity's sake, a section through a single-component applicator device 1 is shown. This only serves to explain the geometric relationships. Of course, the graphic representation according to FIG. 2 With regard to the choice of materials or choice of the manufacturing process is not a restriction. Without further notice, the bristles 5 or 6, as previously described, also made of a different material than the core.

The free bristle end 8 of a bristle 5 is inclined at an angle γ to the longitudinal axis L. The application member 5 has the center axis M, which is formed by the two-dimensional focal points of cuts through the bristle 5 along its longitudinal course from the bristle foot 7 to the bristle end 8 out. At at least one location, the central axis M has a turning point W, in the vicinity of which the curvature of the central axis M changes. A tangent T through the inflection point W intersects the longitudinal axis L at an angle β. For the angle α, values of 30 ° to 90 °, in particular values of 50 ° to 70 ° have been found to be positive. For the angle β, angles in the range between 0 ° and 90 °, in particular between 25 ° and 75 °, have been found to be positive. The angle γ is preferably smaller than the angle α or equal and is in the range between 10 ° and 90 °, in particular between 40 ° and 70 °.

The course of the central axis M away from the bristle foot 7 can also run at least piecewise, so that e.g. over a distance s which, for example, goes off the bristle foot 7 a bit, the curvature 0 is present, i. the central axis M forms a straight piece. In a preferred manner, an applicator member 5 according to the applicator according to the invention has a point of inflection W, so that along the course, for example from the bristle 7 to the inflection point W is a curve with a first sign and from the inflection point W to the bristle end 8 a curvature with opposite Sign exists.

Preferably, the central axis M of the applicator member 5 in the region between the bristle 7 and the inflection point W is less curved than in the region between the inflection point W. and the free bristle end 8. The curvature may be constant in the areas between the bristle foot 7 and the inflection point W and / or in the region between the inflection point W and the free bristle end 8 or may change continuously, possibly also suddenly. It is particularly preferred if, in particular in the area around the point of inflection W, the change of the curvature from a first sign to the opposite sign is continuous, ie without bending radius jumps.

In FIG. 2a a further embodiment of an applicator member of the applicator device according to the invention is shown. In contrast to the above-described applicator 5 according to FIG. 2 is the free end 8 of the job organ according to FIG. 2a designed to the core 2 indicative and forms the applicator member 5 through a gap S ₁ . As a result, an eyelet, a loop-like loop 200 is formed, which may optionally serve as a further away from the core 2 mascara reservoir. Through the gap S ₁ , at least individual eyelashes can enter into the loop 200 when applying mascara mass, for which a particularly good all-round wetting result can then be achieved. Depending on the choice of the size of the gap S ₁ , which may preferably be a few 10-th to a few millimeters, for example 0.1 mm to 2 mm, in particular 0.1 mm to 1.0 mm, it can also be ensured that if appropriate, eyelash bundles enter the loop 200. In this case, a special bundling effect can be achieved.

FIG. 2b shows a further embodiment of an application member of the applicator device according to the invention. The tangent T through the point of inflection W encloses an angle β 'with the longitudinal axis L, wherein the angle β' may be in the range between 0 ° and 90 °, in particular between 25 ° and 75 °.

Furthermore, in the embodiment according to FIG FIG. 2b the angle γ 'the angle γ FIG. 1 and is in contrast arranged in mirror image.

Suitable and preferred values for the angle γ 'are in the range between 10 ° and 90 °, in particular between 40 ° and 70 °.

With this design, in addition to the mascara reservoir of the loop 200, it is possible to create another mascara reservoir 201 closer to the core, which is overhanging the applicator element 5 like a roof.

In the following, further embodiments of the applicator device according to the invention will be described with reference to FIGS Figures 3 to 7a explained. More specifically, however, the differences will be made only to the embodiment already described in detail FIG. 1 and 2 resorted. In that regard, what has been described above and similarities of the following embodiments applies accordingly to all embodiments.

The applicator 1 according to FIG. 3 represents a further embodiment and differs from the embodiment according to FIG. 1 in that the core 2 in the region 2 to the distal end 4 is tapered conically. The core 3 in the area B ₁ , however, is cylindrical. The Auftragorganbesatz the applicator 1 according to FIG. 3 is consistently of type 1, so that all order organs are corrugated bristles 5, which preferably have identical geometrical spatial form with each other. Characterized that the core tapers conically in the area B ₂ , the applicator 1 can be formed conically tapered as a whole to the free end 4, although the application organs 5, ie the corrugated bristles 5 all have the same spatial shape. That related to FIG. 1 and FIG. 2 to the bristle geometry said applies to according to this embodiment. Likewise the length and distance indications of the rows R ₁ , R ₂ , R ₃ and R _I , R _II , R _III as well as the lengths l ₁ , l ₂ as well as d and s.

A further embodiment of the applicator device 1 according to the invention FIGS. 4, 4a , in which FIG. 4a the applicator device according to FIG. 4 in a longitudinal sectional view shows.

In this embodiment, the core 2 is continuously formed cylindrical up to the free end 4. So that a conical tapering of the envelope is ensured towards the free end 4, the corrugated application organs 5 are conically cut to the free end 4 and thus shortened along its longitudinal axis M. Such shortening may take place following an injection molding process by cutting or grinding. However, it can also be provided that the shortened outlet of the applicator elements 5 toward the free end 4 in the injection molding tool, i. already provided in the master mold.

A further embodiment of the applicator device according to the invention is shown in FIG FIGS. 5 and 5a , This applicator device is based on a basic arrangement of the application organs 5 according to the FIGS. 4 and 4a out. Again, the order organs 5 are formed shortened towards the free end 4. It comes along over the entire length of the bristle l ₁ + l ₂ cylindrical core used. Compared to an applicator according to FIG. 4 the order organs 5 adjacent rows R ₁ , R ₂ , R _{3 are} each arranged rotated by 180 ° to each other, so that the order organs 5 a row R ₁ leave an upper side of the core 2 in the direction of the free end 4 and also their bristle ends 8 to towards the free end 4. Application organs 5 of an adjacent row R ₂ are arranged exactly the other way around and leave the upper side of the core 2 in FIG Direction to the proximal end 3 out. Their free bristle ends 8 also point towards the proximal end 3. As a result, reservoir volumes V _{R are formed} in the region of a core 2. The reservoir volumes V _R are essentially surrounded by convexly curved bristle sections B _{A1 of} adjacent bristles 5 facing away from each other, these areas B _A1 and B _A2 belonging to bristles of adjacent rows R ₁ , R ₂ , R ₃ .

Concave areas B _A3 and B ₄ B of adjacent bristles 5 which are curved towards one another are situated outside the respective turning points W or turning areas and thus form a side view according to FIG FIGS. 5, 5a a funnel-shaped, tweezer-like eyelash catching and / or bundling device. As a result, in particular a good 360 ° round wetting is achieved for the eyelashes, so that a good transfer of mascara to the eyelashes or eyelash bundles takes place.

With regard to their geometrical spatial form, the bristles of adjacent rows R ₁ and R _{2 are} preferably of identical construction and are arranged on the core 2 only offset by 180 ° with respect to the longitudinal direction 100. Of course, it is also in the field of the invention, the geometric space shape of the order organs of adjacent rows R ₁ , and R _{2 form} differently.

According to a further embodiment of the applicator device according to the invention ( Figures 6 and 6a ) such an applicator device 1 in turn has a cylindrical core 2 in the region B ₁ and a conically tapered core 2 in the region B ₂ to the free end 4. The stocking of areas B ₁ and B ₂ with order organs corresponds to that of the example described above FIGS. 5, 5a , So there are each order organs 5 adjacent rows R ₁ and R ₂ in the opposite direction Bezgl. The longitudinal direction 100 disposed on the core 2.

Another embodiment ( Figure 7, 7a ) of the applicator device 1 according to the invention combines in the area B ₁ the bristle facing according to the embodiments 5 and / or 6 with the bristle facing in the area B _{2 of} the embodiment according to FIG FIG. 1 ,

Of course, in all the above-described embodiments, the free ends 4 (distal ends), in contrast to the illustrated and described embodiments, on the free end face have a bristle trim / a trim with applicators organs. Such applicators can of course also have the above-described corrugation essential to the invention. This Auftragorganbesatz on the face of the distal end 4 can of course be accomplished with already known order organs other geometric space forms.

On the basis of the plurality of embodiments, it is clear that fundamentally different regions B ₁ and B ₂ may be present in the longitudinal direction, which have different application organ assignments. For example, it is also possible to provide, instead of cone-shaped tapered bristles 6 for type 2, application elements in the manner of discs, disc segments, grooves or the like. Likewise, it is also possible to occupy the succession of rows R _I , R _II , R _III in the circumferential direction U with different application organs 5, 6. Thus, for example, a row I of corrugated application organs 5 exist, whereas an adjacent row II, for example, consists of a serrated or otherwise comb-like web. In addition, order organs may be present in the series II, the conical, pointed-skeletal or form cylindrical bristles. These order organs can also be validated among each other.

Characteristic of the invention is that an applicator device according to the invention has at least one applicator element 5 with a corrugation, as set forth in claim 1. The stocking of the other applicator devices can be filled with order members of another type. Such types of order organs are known from the prior art in many ways. Representative of this are cylindrical, conical bristles, discs, disc segments, grooves or the like. In a particularly preferred manner, these application organs are also preferably connected as integral as possible with the core 2, so that the applicator device 1 by means of a primary molding process, in particular, e.g. can be produced by means of a plastic injection molding process (also 2- or multi-component method) as well as by means of a three-dimensional printing process.
