FIRST EXEMPLARY EMBODIMENT

[0061] FIGS. 1 to 4 show a first exemplary embodiment. The best overview of the first exemplary embodiment is obtained by viewing the FIGS. 1 and 3 together.

The Core

[0062] The applicator 1 consists of an, as a rule, central core 2 forming an essential constituent element of the applicator. The core is preferably situated on the central longitudinal axis about which the wings, which will have to be discussed below, group.

[0063] The cross section of the core preferably is circular, as can best be seen in FIG. 4. The core 2 is followed by a coupling portion 3, which serves for coupling the applicator to a stem which is not shown here, and which as a rule is in turn connected to a handle, or directly to a handle not shown here. The core 2 and the coupling portion 3 are most frequently configured in an integral manner and are in that case preferably manufactured from a uniform material by means of injection molding.

[0064] The core 2 definesmost frequently together with the coupling portion 3a longitudinal axis L of the applicator. As is shown in FIG. 2, the core extends along the longitudinal axis with a length K.

[0065] The core preferably consists of solid material, as is shown in FIG. 3. Alternatively, however, it may also be configured as an internally hollow tube, as is explained in more detail below for a different exemplary embodiment.

[0066] The core has a rigid annular portion which is continuously closed in the circumferential direction and is directly covered with solid fingers as they will be described below.

The Wings

[0067] Preferably, the core 2 is covered all around with wings 4, wherein preferably four, and even better at least six wings 4 are distributed around the core.

[0068] Ideally, the wings 4 are spaced apart from each other at identical distances. The wings 4 are hinged to the core 2 in a pivotable manner about a preferably line-shaped pivot axis 6. This line-shaped pivot axis preferably extends parallel to the longitudinal axis L of the applicator. In the exemplary embodiment described here, each wing is directly connected to the core 2 over the entire length along the line-shaped pivot axis 6. This may be advantageous for certain exemplary embodiments but is not an absolute necessity.

[0069] Each of the inventive wings 4 does not extend over the entire length K of the core, but only over a fraction thereof, which in the present exemplary embodiment is 1/n, where n=1.25. The reason for this will be described in more detail below. Ideally, this applies to all wings provided.

[0070] In this exemplary embodiment, each of the wings 4 is configured as a rectangular strip whose width in the circumferential direction preferably corresponds to at most 2.5 times the bristle base diameter, and better only at most 1.5 times the bristle base diameter.

[0071] In this exemplary embodiment the wings pivot in an identical manner in the clockwise and the counter-clockwise direction, that is, except for the direction, they come closer to the core in the same manner if pivoted in the clockwise or counter-clockwise direction. Pivotability is provided by the rectangular strip as such, provided it is sufficiently flexible. Alternatively, it may also be provided that the rectangular strip has a local thin portion acting as a film hinge which, however, is not shown by the Figures.

[0072] The lateral main surfaces of the strip, which at the same time form the predominant part of the free surface of the strip, are oriented, substantially or even completely, radially in this exemplary embodiment. Ideally, the same applies to the fingers 7, which are to be discussed below. Due to this comparatively thin configuration, the strips are flexible in the circumferential direction, i.e. they are able to pivot back and forth in the circumferential direction.

[0073] The deflection of the strips on the core 2 is so flexible that the strips as such can be pivoted by at least +/15 in the circumferential direction under the influence of the forces arising during the course of the application.

The Fingers

[0074] The respective wing, or in this case the radially outward end face of the strip, is covered with fingers. Preferably, a row of fingers placed one behind the other in alignment along the longitudinal axis L is provided. The fingers may each have the shape of a singular rod or cone, so that then, they form a kind of comb, regardless of whether the fingers 7 are real teeth of a comb or bristles. It is particularly preferred if the length of the fingers 7 with which a wing 4 is equipped decreases from the center of the wing towards the distal end and/or proximal end, ideally by at least of the absolute value of the total length.

[0075] Equipping the wings with alternating finger rows was found to be particularly beneficial. Such an alternating finger row is characterized in that, in the direction parallel to the longitudinal axis, purely radially oriented fingers 7 are arranged alternatingly, and pairs of inclined fingers 8, which are oriented next to one another in the circumferential direction and form a V-shaped configuration. Ideally, exactly one radially oriented finger 7 and one pair of inclined fingers 8 alternate in each case. This can be seen best in FIG. 4. This finger configuration results in a particularly good mass storage capacity, because the total free surface available on the fingers is increased, so that thus, much of the compound can be discharged if the compound is relatively thin and therefore forms only a thinly adhering layer on the surface of the respective fingers.

[0076] Between two wings 4 that are directly adjacent in the circumferential direction, the central core 2 preferably carries no fingers, as is best seen in FIG. 2. This applies particularly to the case where V-shaped pairs of fingers 8 with an inclined orientation are present on the wings. It is thus ensured that the fingers may be folded down unimpededly in and opposite to the circumferential direction.

[0077] However, not only the wings 4 are equipped with fingers in the present exemplary embodiment. In addition, the core 2 in this case carries, both distally and proximally, an annular, wing-free portion 9 that is continuously closed in the circumferential direction. This portion is equipped with immovable fingers 10, preferably all around its circumference. These fingers 10 are referred to as immovable fingers because the base surface of the fingers 10 is in each case directly and therefore immovably attached to the core 2 or its rigid annular portion 9. In this case, the fingers may in actual fact be movable above their base surface, due to their inherent flexibility. Ideally, at least three collars of immovable fingers 10 disposed one behind the other in alignment in the circumferential direction are provided on the or on each of the two annular portion(s) 9, as can be seen best in FIG. 2.

[0078] Generally, the immovable fingers 10 are predominantly disposed in such a way that the majority thereof extends in the radial direction, particularly in the immediate vicinity of the end face of the wings 4 (immediate vicinity: preferably with a distance of three or four finger collars). Ideally, the immovable fingers 10 are set up as finger collars in which each finger collar is formed from solid fingers 10 placed one behind the other in alignment in the circumferential direction, see FIGS. 10 and 11. In this case, it is particularly useful if the immovable fingers of finger collars adjacent in the direction of the longitudinal axis L are placed one behind the other in alignment, also in each case as viewed in the direction of the longitudinal axis L. Ideally, the length of the immovable fingers 10 increases in each case from the distal end to the start of the wing, or from the proximal end to the start of the wing. In that case, the immovable fingers 10 can form wedge arrangements over which the wiper lips are guided towards the initial part of the wings, as is shown in FIGS. 10 and 11. In this case, it is particularly useful if the immovable fingers 10 are in each case arranged in alignment with the strips forming the wings 4 and their fingers 7. In this case, it may also be particularly useful if other ones of the immovable fingers 10 form a row in alignment in the direction of the longitudinal axis L, which at the same time is in alignment with the intermediate space between two directly adjacent wings 4 that is not covered with bristles.

[0079] In this case, a finger in the sense described here is understood to be either (completely or at least substantially) rigid teeth of a comb or bristles. Bristles are clearly preferred. The term bristles preferably refers to rod-shaped structures that are so flexible that, under the influence of the forces arising during application, their tips can be laterally deflected in a reversibly elastic manner by the amount S, which is at least 4 times the bristle base diameter BF (as defined above), as is shown in FIG. 30. The bristle base diameter BF is preferably between 0.25 mm and 0.75 mm, ideally between 0.3 mm and 0.45 mm.

[0080] Ideally, bristles situated one behind the other in alignment in the direction parallel to the longitudinal axis, provided they are situated in direct succession, are spaced apart by a minimum distance of 1.5 BF, better 1.75 BF.

[0081] Expediently, the bristles have a conical shape, with a cone angle which is normally between 0.5 and 3.5.

[0082] The length of the bristles LB between the bristle base above the rounded portion, with which the bristle may transition into the respective slotted tube, preferably is between 4 mm and 15 mm, better between 0.5 mm and 12 mm.

[0083] It is particularly beneficial if at least one, and better still, as shown here, all of the wings 4 are at least partially, better predominantly, and ideally completely, covered with bristles. In order to optimally take advantage of the particularly large application surface provided by these peculiar wings, each applicator is covered with at least 75 bristles, better with at least 100 bristles.

[0084] In order to provide the bristles with a particular application behavior, it may be useful to manufacture the bristles from a different plastic material than the core. In that case, the plastic material of the bristles is subsequently attached by injection-molding, preferably together with the entire respective wing 4. This preferably means that the wings with the bristles consist of one, and the core of another, plastic material.

The Effect

[0085] The strong point of the exemplary embodiment according to the invention is that, on the one hand, it has pivotable wings 4 that fold down laterally when passing through the wiper, thus reducing the outer diameter of the finger covering when passing through the wiper, and, on the other hand, it is equipped at the proximal end and/or at the distal end with a covering of immovable fingers 10 in the above-mentioned sense, which is at least substantially or completely closed in itself in the circumferential direction. As a result of this covering of immovable fingers 10, the wiper lip does not impact the end face of the wings 4 too abruptly, either getting caught there or laterally folding down the wings 4 in an undefined manner with great force, when the applicator is withdrawn from the cosmetics storage container or when the applicator is inserted into the cosmetics storage container. This is due to the fact that, with the design according to the invention, the wiper lip first impacts the immovable fingers and is thus lifted slightly, in order to then be able to slide into the region of the outer circumference of the wings without any problems. At the same time, another possible result is that the wiper lip does not jump off the respective wing too abruptly at the end of a wing 4, causing fine splashes of cosmetic compound to be thrown off laterally.

Other Remarks

[0086] In some cases, it may be particularly useful if the distal end is (also) provided with immovable fingers 12, whose longitudinal finger axis does not extend perpendicularly to the longitudinal axis L of the applicator, but at an angle of less than 75 to the longitudinal axis, so-called inclined immovable fingers. It is ideal if these inclined immovable fingers 12 form a rotationally symmetric hedgehog as shown by the FIGS. 9 and 10, to which reference is already made in advance. The term immovable fingers also in this case follows the definition already given above.

[0087] The hedgehog is preferably provided with inclined immovable fingers 12 extending at an angle of between 75 and 60, with further fingers 12 extending at an angle of between 60 and 45, and with further fingers 12 that assume an angle of between 45 and 30 to the longitudinal axis L. Ideally, at least one immovable finger 12 is additionally provided which is oriented parallel to the longitudinal axis.

[0088] Such a design offers a very high degree of variability in application. Because the cosmetic compound can be applied both by means of the fingers forming the hedgehog and, alternatively, by means of the radially oriented immovable fingers, and finally, again alternatively, also by means of those fingers that are supported by the wings.

SECOND EXEMPLARY EMBODIMENT

[0089] FIGS. 5 to 8 show a second exemplary embodiment. The second exemplary embodiment corresponds completely to the first exemplary embodiment, with the exception of the differences described below. For this reason, all of the previous description regarding the first exemplary embodiment also applies to the second exemplary embodiment.

Different Hinge Mounting of the Wings

[0090] In the second exemplary embodiment, the wings are basically configured in the same way as in the first exemplary embodiment. The sole difference is that the wings 4 are directly attached to the core 2 not over their entire length, but only at several spaced-apart connecting portions 11. In the present case, each of the wings 4 preferably has one connecting portion 11, respectively, in the region of its distal and its proximal end, and preferably also in the region of its center an additional third connecting portion 11. In principle, it is possible that the third connecting portion is itself divided into two parts and thus forms a total of two further connecting portions disposed to the left and the right next to the center of a wing.

Internally Hollow Core

[0091] Optionally, another difference may be that the core 2 of the applicator is formed to be hollow, preferably over its entire length, preferably just up to the coupling portion, as is shown in the present case by FIG. 7. Together with the only locally hinged wings, which for precisely this reason increase the geometrical moment of inertia only to an insubstantial extent, this provides the applicator with the capability of elastically yielding in its entirety in the direction perpendicular to its longitudinal axis and, figuratively speaking, be curved in its entirety in a banana shape.

Two-Component Injection-Molding

[0092] As can best be seen in FIG. 7, there is the option of attaching by injection-molding the rigidly attached fingers 10 and/or the wings 4 including their fingers 7 and 8 to the core 2, which consists of a first plastic. This is advantageous in that a second plastic with different properties can be used for the finger and/or wings with fingers to be attached by injection-molding, e.g. a plastic that is more elastic and/or softer, such as a TPE.

THIRD EXEMPLARY EMBODIMENT

[0093] FIGS. 9 to 12 show a third exemplary embodiment. The third exemplary embodiment corresponds to the first exemplary embodiment and/or the second exemplary embodiment, at least with respect to the covering with rigidly attached fingers 10, and with respect to the type and the pivotable hinge mounting of the wings 4 and their covering with fingers 7 and 8.

[0094] The only substantial difference to the first and second exemplary embodiments is the multi-part design of the wings. As can be seen, several wings 4 are provided here which are placed one behind the other in alignment in the direction of the longitudinal axis L of the applicator, but are nevertheless completely separated from one another. In other respects, the statements in connection with the other exemplary embodiments apply to these wings 4 and their covering of fingers 7 and 8.

[0095] The multi-part design of the wings is of vital significance. Because one of several wings placed independently of one another in the direction of an alignment along the longitudinal axis L as such puts up considerably less resistance to pivoting in the circumferential direction than a single monolithic wing, which extends across nearly the entire core 2 along the longitudinal axis L. Therefore, such a wing offers the possibility of being folded in the circumferential direction not only under the influence of the wiper. Instead, such a wing can also be pivoted in the circumferential direction under the influence of forces otherwise arising during the actual application, i.e. also during the actual work, for example, on the eyelash or the eyebrow. This offers completely novel application properties.

[0096] It is particularly beneficial if a variation is provided between the adjacent rows of wings 4 placed in alignment along the longitudinal axis Lin the sense that one row consists of two wings placed one behind the other in alignment along the longitudinal axis L, and adjacent row consists of three wings placed one behind the other in alignment along the longitudinal axis L, wherein it is also possible, as an alternative, that four such wings are being used in this case.

FOURTH EXEMPLARY EMBODIMENT

[0097] FIGS. 13 to 15 show a fourth exemplary embodiment. The fourth exemplary embodiment has a fundamentally different design from the previous three exemplary embodiments described so far. With the exemplary embodiments already described, they only have the fact in common that the core 2 may be massive or internally hollow, and that the wings 4 may be connected to the core over their entire length or only at several spaced-apart connecting portions 11. These connecting portions 11 may in that case be arranged as already described above. Also in this case, an internally hollow core, together with wings that are directly connected to the core only at several spaced-apart connecting portions 11, provides the core an advantageous elasticity or deflectability, i.e. the capability to be deflected as a whole in the direction perpendicular to the longitudinal axis L that it reflects in the state of rest. The fingers, i.e. the teeth of a comb or bristles, are designed in this exemplary embodiment as was described above in connection with the first exemplary embodiment.

The Core

[0098] The core 2 definesmost frequently together with the coupling portion 3a longitudinal axis L of the applicator. As is shown in FIG. 14, the core extends along the longitudinal axis with a length K. The core preferably consists of solid material, as is shown in FIG. 3. Alternatively, however, the core may also be configured as an internally hollow tube, as was already explained above. This is preferably accompanied by an only local hinge mounting of the wings 4.

The Wings

[0099] Preferably, the core 2 is covered all around with wings 4, wherein preferably four or at least six wings 4 are distributed around the core. Also in this case, preferably none of the wings 4 extends across the entire length K of the core. Instead, each wing 4 according to the invention extends only across a fraction of the length K of the core, which in the present exemplary embodiment is 1/n, where n<1.7.

[0100] Ideally, the wings 4 are spaced apart from each other at identical distances. The wings preferably form several wing collars which, viewed in the circumferential direction, consist of wings disposed one behind the other in alignment (if the applicator is pictured in an unreeled state). In the present exemplary embodiment, two such wing collars are provided.

[0101] The wings are hinged to the core in a pivotable manner about a preferably line-shaped pivot axis 6. This line-shaped pivot axis preferably extends parallel to the longitudinal axis L of the applicator. In the exemplary embodiment according to the invention which, however, is not shown in a Figure, each wing is directly connected to the core 2 over the entire length along its line-shaped pivot axis 6. This may be advantageous for certain exemplary embodiments but is not an absolute necessity. In order to improve pivotability, it may be provided in this case that the line-shaped pivot axis is constituted by a local thin portion forming a film hinge.

[0102] Alternatively, it may be provided, as shown by the FIGS. 13 to 15, that each wing 4 is directly connected to the core only at several spaced-apart connecting portions 11, as shown in FIGS. 13 to 15. In the present case, each of the wings preferably has one connecting portion 11, respectively, in the region of its distal and its proximal end. If required, each wing 4 could also have an additional third connecting portion in the region of its center which, however, is not necessary here due to the relatively limited length of the wings. The connecting portions 11 may each have a local thin portion forming a film hinge. As can very easily be seen in FIGS. 13 to 15, the wings 4 are in this case hinged like flaps that are pivotably disposed on the core 2 at one of their end faces forming the edge of the large main surfaces, in any case outside every one of their axes of symmetry. In this case, the deflection is such that the wings 4, if pivoted in the counter-clockwise direction, for example, first gain a greater distance from the core 2 and, if pivoted in the opposite direction, e.g. in the clockwise direction, immediately assume a smaller distance from the core 2. Thus, the wings in this fourth exemplary embodiment are preferably disposed so as to pivot all in the same direction.

[0103] In this exemplary embodiment, several wings may also be hinged to the core 2 one behind the other in alignment parallel to the longitudinal axis L, which is not shown here in a Figure. Instead, two wings 4 situated in direct succession in the direction of the longitudinal axis L may preferably have a pivot axis offset, which is configured in such a way that the pivot axes that are not in alignment in the direction along the longitudinal axis L are disposed parallel to each other and have a minimum axis offset in the circumferential direction of 0.5 mm to 1.5 mm. This can be seen rather well in FIG. 13. Because the imaginary line about which the wing 4 pivots that is disposed closer to the distal end in FIG. 13, measured in the circumferential direction, is disposed approx. 1 mm next to the imaginary line about which the wing pivots that is disposed closer to the proximal end in FIG. 13. In this manner, a variable application behavior is obtained because the fingers of two wings 4 situated in direct succession in the direction of the longitudinal axis L do not all point in the same direction, but are slightly offset relative to one another, which is very easily seen in FIG. 15.

[0104] As can best be seen in FIG. 13 and FIG. 15, the wings are in this case designed as plates whose entire inner main surface is convexly curved in order to ensure that they can be bought as close to the core 2 as possible. The entire outer main surface of the wings is preferably concavely curved (see FIGS. 13 and 15), which perceptibly improves the interaction between the respective wing 4 and the wiper lip, which is not shown here.

[0105] It is particularly beneficial if the unilaterally hinged plates forming the wings 4 are beveled on at least one of their end faces, better on both end faces (distal and proximal), by an angle of 25 to 60 and ideally by an angle of 40 to 50, measured relative to the pivot axis of the wings. Said angle is measured by projecting the edge of the beveled end face onto the longitudinal axis L and then measuring the angle. Such a limitation means that the surface of the end face is beveled over the entire surface. Such a bevel of the entire front edge offers the decisive advantage that the front edge comes into contact with the wiper lip not in its entirety, but only successively, when inserting the applicator into the cosmetics storage container or when withdrawing the applicator from the cosmetics storage container. In this manner, a run-on slope is formed which prevents the wiper lip from getting caught on the end face of the wing. Instead, it becomes possible that the wiper is pushed, by and by, onto the outer circumference of the wing during the further movement after the impact on the frontal edge of the wing.

[0106] The fact that each wing extends only over a fraction of the length K along the longitudinal axis L makes another essential contribution to this. In this manner, each individual wing can be pushed in the direction of the core 2 or in the opposite direction very easily and with little force. For this reason, an applicator can be created in which the outer diameter of the application-ready finger covering can be reduced very easily in order to have the applicator pass through the bottle neck without any problems, and without having to provide the bottle neck with an unacceptably large diameter.

The Fingers

[0107] As can be easily seen in the Figures, each of the wings is provided with a plurality of fingers on its outer main surface. Preferably, the fingers project from the outer main surface of the respective wing, inclined at an angle BETA relative to the normal to the local tangent through the finger base point. In this case, the fingers are organized in rows of fingers situated in alignment parallel to the longitudinal axis L. Ideally, they simultaneously form finger collars of fingers placed one behind the other in alignment, when viewed in the circumferential direction. This can be seen rather well in FIG. 4.

FIFTH EXEMPLARY EMBODIMENT

[0108] FIGS. 16 to 18 show a fifth exemplary embodiment. The fifth exemplary embodiment is identical to the fourth exemplary embodiment, so that the statements pertaining thereto also apply to the fifth exemplary embodiment with the exception of the differences described hereinafter.

[0109] In this fifth exemplary embodiment, two wings situated in direct succession in the direction of the longitudinal axis L are provided with a pivot axis offset.

[0110] In this exemplary embodiment, two wings 4 situated in direct succession in the direction of the longitudinal axis L have a pivot axis offset, which is configured in such a way that the pivot axes that are not in alignment in the direction along the longitudinal axis L are disposed parallel to each other and at the same time have a large axis offset in the circumferential direction of 1.5 mm to 3 mm. This can be seen rather well in FIG. 16. Because in this exemplary embodiment, the imaginary line about which the wing 4 pivots that is disposed closer to the distal end in FIG. 16, measured in the circumferential direction, is disposed approx. 2.5 mm next to the imaginary line about which the wing pivots that is disposed closer to the proximal end in FIG. 13. In this manner, a variable application behavior is obtained because the fingers of two wings 4 situated in direct succession in the direction of the longitudinal axis L do not all point in the same direction, but are offset slightly relative to one another, which is very easily seen in FIG. 15.

[0111] Furthermore, it can easily be seen in FIG. 18 that this technical issue, which is essential for the fifth exemplary embodiment, may also be expressed in slightly different words: In this fifth exemplary embodiment, two wing collars are provided that are respectively offset relative to each other in the circumferential direction that the imaginary pivot line of one wing of the front wing collar is located right in the center of the intermediate space between two wings of the rear wing collar that are directly adjacent in the circumferential direction.

SIXTH EXEMPLARY EMBODIMENT

[0112] FIGS. 19 to 21 show a sixth exemplary embodiment. The sixth exemplary embodiment is identical to the fourth and fifth exemplary embodiments, so that the statements pertaining thereto also apply to the sixth exemplary embodiment with the exception of the difference described hereinafter.

[0113] As can very easily be seen in the Figures, the wings 4 are also in this case hinged like flaps that are pivotably disposed on the core 2 on one of their sides, outside every one of their axes of symmetry.

[0114] In this case, what is essential to this exemplary embodiment is that the applicator has two wings that pivot in opposite directions. In this case, the deflection is such that one of these wings pivoting in opposite directions, if pivoted in the counter-clockwise direction, for example, first gains a greater distance from the core 2 and, if pivoted in the opposite direction, e.g. in the clockwise direction, immediately assumes a smaller distance from the core 2. The exact opposite is true for the other one of the wings pivoting in opposite directions. It immediately assumes a smaller distance from the core 2 if pivoted in the counter-clockwise direction, for example.

[0115] Advantageously, the wings 4 are configured as wing collars in the above-mentioned sense, wherein the applicator preferably exhibits at least two wing collars, as can best be seen in FIG. 19. Ideally, all wings of a wing collar pivot in the same direction, and the finger collars are in this case organized in such a way that adjacent wing collars have wings that pivot in opposite directions. This is also illustrated well in FIG. 19 and FIG. 21.

[0116] Also for this embodiment, it is of particular significance that each wing extends only over a fraction of the length K along the longitudinal axis L. Due to its extent in the direction along the longitudinal axis L being only short, each of the wings can be easily pivoted by the forces arising during application, e.g. near the eye or on the eyebrow, and therefore offers a very pleasant, yielding application behavior. In this case, the applicator offers an application behavior with a hitherto unknown variability, due to the wings 4 pivoting in opposite directions.

[0117] What must also be emphasized is that wings 4 that are situated in direct succession in the direction of the longitudinal axis have a pivot axis offset also in this exemplary embodiment, preferably in the form of the large axis offset already described in connection with the fifth exemplary embodiment, as is illustrated by the FIGS. 19 to 21.

[0118] It must also be remarked that plates that are successively arranged or are directly adjacent in the direction of the longitudinal axis L have equidirectionally beveled end faces. In this regard, reference is to be made to FIG. 20. The bevel, which the wings that belong to the distal wing collar have on their side facing towards the middle, extends in the same direction as the bevel that the end faces of the wings belonging to the proximal wing collar have on their side facing towards the middle. It is thus ensured that no interfering contact can occur between the wings, even without the wings being required to have a particularly large distance from one another.

SEVENTH EXEMPLARY EMBODIMENT

[0119] FIGS. 22 to 24 describe a seventh exemplary embodiment. The seventh exemplary embodiment corresponds to the sixth exemplary embodiment, so that the statements above pertaining to the sixth exemplary embodiment also apply to the seventh exemplary embodiment.

[0120] There is only one difference between these exemplary embodiments.

[0121] This is that the wings 4 in this exemplary embodiment have no pivot axis offset. This means that the imaginary pivot axes of two wings that are successively arranged or are directly adjacent in the direction of the longitudinal axis L are in alignment, as can best be seen in the FIGS. 22 and 24.

[0122] Possibly, another alternative is to provide this exemplary embodiment with a minimum axis offset, as was already explained above for one of the preceding exemplary embodiments. This alternative is not shown in a Figure here.

EIGHTH EXEMPLARY EMBODIMENT

[0123] FIGS. 25 to 29 show an eighth exemplary embodiment. The eighth exemplary embodiment has a fundamentally different design from the previous seven exemplary embodiments described so far. However, various technical configuration possibilities of this exemplary embodiment correspond to what was previously described with respect to the fourth to seventh exemplary embodiments, so that those descriptions also apply mutatis mutandis to the eight exemplary embodiment unless otherwise evident from the following explanation. It must also be remarked that the statements pertaining to the fingers or bristles and/or teeth of a comb in the context of the first embodiment also apply to this exemplary embodiment.

The Core

[0124] The core 2 definesmost frequently together with the preferably provided coupling portion 3a longitudinal axis L of the applicator. As is shown in FIG. 14, the core extends along the longitudinal axis with a length K. The core preferably consists of solid material, as is shown in FIG. 3. Alternatively, however, the core may also be configured as an internally hollow tube, as was already explained above. The latter is then preferably accompanied by an only local hinge mounting of the wings 4.

The Wings

[0125] Preferably, the core 2 is covered all around with wings 4, wherein preferably 12 or at least 16 wings 4 are distributed around the core in this embodiment. In this case, preferably none of the wings 4 extends across the entire length K of the core. Instead, each wing 4 according to the invention extends only across a fraction of the length K of the core, which in the present exemplary embodiment is 1/n, where n<3.

[0126] Ideally, the wings 4 are spaced apart from each other at identical distances. The wings preferably form several wing collars which, viewed in the circumferential direction, consist of wings disposed one behind the other in alignment (if the applicator is pictured in an unreeled state). In the present exemplary embodiment, five such wing collars are provided. Generally speaking, it may be remarked that an applicator is in accordance with the invention already when two such wing collars are present, but that advantageously at least three such wing collars should be present.

[0127] The wings are hinged to the core in a pivotable manner about a preferably line-shaped pivot axis 6. The salient feature of this exemplary embodiment is that the line-shaped pivot axis extends in an inclined manner relative to the longitudinal axis L of the applicator.

[0128] The line-shaped pivot axis, if mentally projected onto the longitudinal axis L, ideally includes an acute angle ALPHA therewith, which is preferably open towards the proximal end of the applicator and is most frequently in the range between 30 and 75, while ideally being in the range between 35 to 55.

[0129] In the exemplary embodiment according to the invention which, however, is not shown in a Figure, each wing is directly connected to the core 2 over the entire length along its line-shaped pivot axis 6. This may be advantageous for certain exemplary embodiments but is not an absolute necessity.

[0130] In this exemplary embodiment, the connection of the wings to the core 2 in the area of the pivot axis is of particular interest. In theory, the wings 4 may be directly connected to the core only on one corner, via a connecting portion 13. Such a connection of the wings is chosen if the wings are to be movable not only in such a way that they can be folded closer towards the core of the applicator or folded farther away from the latter, but if there is an additional demand for pivoting the wings in such a way that the angle of the lower edge of the wing facing towards to core changes relative to the longitudinal axis L.

[0131] Preferably, however, the wings 4 have, at the edge thereof facing towards the core 2, another connecting portion 14 that grasps around a part of the jacket surface of the core 2 and integrally transitions into the core 2 in this area.

[0132] Expediently, this connecting portion is so thin, in the direction perpendicular to the pivot axis, that it permits an elastic pivotability of the wings 4. In this case, it is particularly beneficial if the connecting portion 14, and preferably also the connecting portion 13, each have their own or a common local thin portion forming a film hinge 15.

[0133] It is particularly beneficial if the unilaterally hinged plates forming the wings 4 are beveled on at least one of their end faces, better on both end faces (distal and proximal), by an angle of 25 to 60 and ideally by an angle of 40 to 50. Said angle is measured also in this case by projecting the edge of the beveled end face onto the longitudinal axis L and then measuring the angle. The term bevel means that the surface of the end face is beveled over the entire surface, measured relative to the pivot axis of the wing.

[0134] Ideally, the limitation is configured such that none of the narrow sides of the wing 4 is orientated completely perpendicularly to the longitudinal axis L, if one views the narrow sides of the respective wing projected onto the longitudinal axis L.

[0135] Such a bevel of the entire front edge offers the decisive advantage that the front edge comes into contact with the wiper lip not in its entirety, but only successively, when inserting the applicator into the cosmetics storage container or when withdrawing the applicator from the cosmetics storage container. In this manner, a run-on slope is formed which prevents the wiper lip from getting caught on the end face of the wing. Instead, it becomes possible that the wiper is pushed, by and by, onto the main outer circumference of the wing during the further movement after the impact on the frontal edge of the wing.
