Definitions
- the invention is directed to a cosmetic applicator, in particular in the form of a mascara applicator, with a core which carries a trimming of fingers protruding therefrom, preferably in the form of bristles.
- a cosmetic applicator in particular mascara mass can be applied to the eyelashes.
- the invention is directed to a method for producing such a cosmetic applicator.
- Such applicators are known in many forms.
- such applicators pose the problem that, on the one hand, optimal loading of cosmetic mass is to be achieved in order to spare the user from having to even interrupt the application several times in order to re-apply the required amount of cosmetic mass to the applicator to load and then continue the application.
- the cosmetic mass taken up by the applicator must be held securely by the applicator and must not drip off unintentionally. This plays a major role, especially in the liquid cosmetic masses.
- the default requirement is that the order organs must have sufficient flexibility.
- the invention is based on the object to provide a Kosmetikapplikator, the increased Mass storage capacity shows without significantly worsening the other relevant order properties.
- the object is achieved in that the trimming has adjacent fingers that are interconnected by a surface element, each integrally connected to the circumferential surface of both fingers and integrally connected to the core and in the direction perpendicular to its two major surfaces have a thickness which is smaller than the maximum diameter of each of the bristles thus interconnected.
- a method for producing a cosmetic applicator according to one of claims 1 - 12 with a trim of molded on a core fingers in which together with the fingers in each case a surface element is injected in the form of a film, each between extends two fingers immediately adjacent and is held spanned by the fingers, wherein the respective surface element is formed integrally with the fingers and the core, preferably injected, is.
- a cosmetic applicator having a core having a trim of fingers extending therefrom, which are preferably bristles.
- immediately adjacent fingers of the trimming are connected to each other by a surface element, which connects in each case locally and in one piece to the circumferential surface area of both fingers.
- the surface element also integrally connects to the core, so it is held not only spanned laterally by the two adjacent fingers to which it is connected, but also from the core.
- the bottom line is that this surface element in the direction perpendicular to its two major surfaces has a thickness which is smaller than the maximum diameter of each of the two fingers thus connected.
- the fingers which are usually executed in the form of bristles, the task is on the one hand to be flexible, but on the other hand, a certain
- the surface element according to the invention is designed so that, at least in the circumferential direction, it does not lead to an increase in the flexural stiffness that causes disturbance.
- the imaginary center longitudinal plane of the surface element is a plane in which the applicator longitudinal axis lies, so that the surface element then protrudes purely radially. Such a positioning of the surface element has proven to be in tests as the most appropriate.
- the invention is therefore characterized in an embodiment further characterized in that the central longitudinal plane of the surface element, in particular of all surface elements, is a plane in which the applicator longitudinal axis is located.
- the said thickness of the surface element may preferably not exceed 55% and better at most 40% of the maximum finger diameter. Since the fingers or bristles and the surface element are made together from plastic, the surface element then behaves like a membrane or a plastic film, which is spanned between the two adjacent fingers or bristles.
- the invention thus also provides, in a further development, for the said thickness of the surface element to be at most 50% of the surface area maximum finger diameter.
- the thickness of the surface element from the core to the radially outward end of the surface element is constant.
- the invention provides that the thickness of the surface element decreases starting from the core towards the radially outward end of the surface element. It is particularly favorable if the surface element has a maximum extent in the radial direction which is smaller than the maximum extent of the two fingers connecting it.
- the maximum radial extent of the surface element is at most 3/4 of the maximum radial extent of each of the two fingers.
- the minimum radial extent of a surface element should be at least 1/3, more preferably at least 1/2 of the maximum radial extent of the two fingers.
- the invention is further distinguished by the fact that the respective surface element in the radial direction has a maximum extent which is smaller than the maximum extent of the two fingers, which it connects, the maximum radial extent of the respective surface element, in particular of all surface elements, preferably between ⁇ and ⁇ the maximum radial extent of the two fingers is. It is particularly advantageous to configure the radially outward, free end face of the surface element curved, preferably concave, which the invention also provides. This causes the individual eyelashes to slip into the middle of the free end face of the surface element, where its concave end face has the lowest point.
- the surface element is a membrane which is deformed by forces acting in the circumferential direction more than slightly insignificant.
- more than insignificant deformation is that deformation above 50/10 mm, or ideally even 10/10 mm, beyond that deformation of one or a few hundredths of a millimeter that virtually every rigid body exhibits under load due to its inevitable elasticity.
- a person skilled in the art understands a membrane that can not transmit a bending moment in the direction parallel to its two major major surfaces.
- a membrane resembles, so to speak, a jumping sheet, which is also able to transmit no bending moment in the direction perpendicular to its large main surface.
- An alternative embodiment of the invention provides that at least one row of zig-zags on the left and right of a parallel to the Applikatorlijnsachse running alignment line behind successively positioned finger belongs to the stocking, which are mainly or preferably all interconnected by surface elements of the said type.
- Such a setup results in a pattern reminiscent of a zig-zag set up, appropriately covered fence. It is furthermore advantageous if the fingers have a gradually decreasing radial extent towards the distal end of the cosmetic applicator, wherein the radial extent of the surface elements preferably likewise decreases, as the invention likewise provides.
- the invention is also characterized in an embodiment in that the surface elements have a sloping free end side towards the distal end of the cosmetic applicator.
- FIG. 1 shows a perspective view of a first embodiment obliquely from above.
- FIG. 2 shows a side view according to FIG. 1.
- FIG. 3 shows the applicator according to FIG. 1 seen frontally from the front.
- FIG. 4 shows a second embodiment, which is closely related to the first embodiment, in side view.
- FIG. 5 shows the embodiment according to FIG. 4 frontally from the front.
- FIG. 6 shows a third embodiment in a perspective view obliquely from above.
- FIG. 7 shows the exemplary embodiment according to FIG. 6 frontally from the front.
- FIG. 8 shows the embodiment according to FIG. 6 in side view.
- FIG. 9 shows a fourth exemplary embodiment in side view.
- FIG. 10 shows the embodiment according to FIG. 9 from the front.
- proximal end the proximal end 9 facing a handle / stem or the distal end 10 of the cosmetic applicator 1 facing away from the handle / stem are referred to.
- the entire or at least the major part of the fingers 4 is in the form of bristles.
- a bristle is understood to mean a rod-like structure whose length Lg is at least 5 times greater than its maximum diameter Dmax above the possibly pronounced rounded region with which the bristle merges into the core 2 of the composite applicator 1. In that regard, reference may be made to FIG. 11.
- a bristle or a finger 4 preferably has a circular or, except for tolerance deviations, at least substantially circular cross-section.
- An oval or elliptical and plum-like cross-section is also conceivable.
- a bristle or finger 4 is characterized by being tapered from its foot to its extreme free end. Therefore, the jacket forming the circumference of a bristle or a finger 4 is particularly preferably conical, with a conical jacket angle of preferably between 1 ° and 3 °.
- a bristle or a finger 4 is typically characterized by its high flexibility in the direction perpendicular to the bristle longitudinal axis BL. In most cases, it is expedient if a bristle or a finger 4 is so flexible that its / its free end elastically reversibly displaces by an amount AL in the direction perpendicular to the longitudinal axis of the bristle BL under the influence of the forces that occur during the application can be at least three times, better at least four times the maximum finger diameter Dmax, like this Fig. 1 can be seen.
- the cosmetic applicator 1 has a core 2.
- the core 2 preferably has a coupling section 3, which is used for coupling
- Cosmetic i kapplikators 1 to a handle, not shown here or a handle, not shown, is used.
- the major part of the core 2 acts as a figure carrier, that is, it is occupied with generally projecting in the radial direction of him fingers 4 or bristles.
- the fingers 4 or bristles are usually made in one piece with the core by injection molding.
- the injection molding gives the fingers 4 or bristles microscopically special properties, because the injection molding is a certain orientation of the plastic molecules in the direction parallel to the longitudinal axis BL of the fingers 4 or bristles, which can be achieved only by injection molding.
- the injection molding leads to the fact that the fingers 4 or bristles pass without a gap in the core 2, which is extremely advantageous for longer-term use of the Ko sme t i kapplikators 1 from a hygienic point of view.
- the fingers 4 or bristles are preferably arranged in rows, at least in the direction parallel to the applicator longitudinal axis L of the cosmetic applicator 1. Adjacent fingers 4 standing in such a row preferably keep a distance from each other which is 2 to 3.5 times times the maximum finger diameter Dmax.
- Kosmet i kapplikatoren 1 is now that the stocking has immediately adjacent fingers 4, the are connected to each other by a surface element 5, which in each case locally and integrally connected to the peripheral surface of the respective mutually adjacent and connected by means of a surface element 5 fingers 4 connected.
- This surface element 5 has, in the direction perpendicular to its two main surfaces 6, a thickness D which is smaller than the maximum diameter of each of the two fingers 4 connected to one another. What is meant by this can be seen very well with reference to FIG. 1. As a rule it is such that the diameter of the fingers 4 is greater everywhere than the thickness D of the surface elements 5. In this way, a closed finger edge is formed in the longitudinal direction.
- the contour of the individual fingers 4 is clearly everywhere, which is why the finger room is pronounced of the dorsal fin of a fish or to a fence, between the fence post clothing is provided.
- the surface elements 5 merge integrally into the core 2 at their radially inward end and are thus connected in one piece to the core 2.
- the radially outward end of the surface elements 5 in each case forms a free end face 8.
- This free end face 8 is preferably concavely curved in this embodiment. Alternatively, however, for example, a V-shaped design of this free end face 8 is conceivable.
- each surface element 5 has a maximum extent in the radial direction, which is less than the maximum extent of the two fingers 4, which connects it. This means that the fingers 4 continue radially above the surface elements 5 and form a free part on all sides, which is freely flexible in all directions. What can be seen only partially with reference to the figures is that each of the surface elements 5 is a membrane, ie an element which can transmit no appreciable bending moments and only tensile forces or at least higher tensile forces than compressive forces.
- Such a membrane is thus a flexible element, which can be deformed more than insignificantly, in particular by forces acting in the circumferential direction, ie a deformation in the range of 1 mm and learn more, rather than just every deformation in the 1/100 mm range, the virtually every rigid body under the influence of external forces shows.
- the flexible surface elements 5 in the form of a plastic film, with a thickness of not more than 3/10 mm and better of not more than 2/10 millimeters.
- the surface elements 5 are produced by being usually injection-molded in one shot together with the core 2 and the fingers 4. Alternatively, it is possible to proceed in such a way that the fingers 4 and the surface elements 5 are subsequently sprayed onto a first injection-molded core 2 in a second step.
- the fingers 4 have a stepwise decreasing radial extent toward the distal end of the cosmetic applicator 1, ie H. towards the distal end the fingers become shorter and shorter.
- the radial extension of the surface elements preferably also decreases.
- the surface elements 5 have a free end face sloping towards the distal end 10 of the composite applicator 1 (notwithstanding their, for example, concave arc), ie. h., A surface element 5 extends on the side where it is connected to a longer finger 4, further radially outward than on the other side, with which it is connected to a shorter finger 4.
- Figures 4 and 5 show a second embodiment, which is a modification of the first embodiment and therefore very similar to this. Because of this, what has just been said for the first embodiment applies equally to this second embodiment, unless clearly different from the differences described below.
- a further preferred difference to be realized here is that the fingers 4 do not have a circular cross section here, but an elliptical or even a substantially rectangular cross section. In this case, the cross section is aligned so that the long semiaxis of the ellipse is oriented parallel to the applicator longitudinal axis L or the long side edge of the rectangle is oriented parallel to the applicator longitudinal axis L.
- the bristle or finger seam sets a deflection of the bristles or fingers 4 in the direction parallel to the longitudinal axis L to a much greater resistance than in the first embodiment.
- the rigidity of the bristles or fingers 4 in this direction and their connection to each other by the surface elements 5 thus add up in their effect.
- the finger stump here is barrel-shaped overall. That is, each row of fingers parallel in the direction parallel to the applicator longitudinal axis L starts at the proximal end 9 of the cosmetic applicator 1 with a short finger 4, then the finger length increases step by step until it reaches a maximum, later it drops again step by step towards the distal end 10 of the cosmetic applicator 1.
- the radial extension of the surface elements 5 between two adjacent fingers 4 increases or decreases correspondingly with the length of the fingers 4, as can be seen in FIG.
- the surface elements 5 are usually designed as a membrane or plastic film and also behave as described above for the first embodiment.
- the maximum extent of each finger 4 in the circumferential direction is greater than the maximum thickness of the membrane or of the surface element 5, the extension of each finger 4 preferably being larger than the thickness of the membrane or of the surface element 5 in the circumferential direction , so that the fingers 4 clear here.
- FIGS. 5 to 8 A further, alternative third exemplary embodiment is shown in FIGS. 5 to 8.
- the fingers 4 are designed as preferably radially outwardly tapering lobes, d. H. as structures which have a greater extension by at least a factor of three in their foot region in the direction of the applicator longitudinal axis L than in the circumferential direction of the co ⁇ sme ti kapplikators 1. Moreover, it is advantageously so that all lobes in the direction of the applicator longitudinal axis L in succession in standing in a row, have a common foot area, the strip-like projecting from the core 2 of the cosmetics 1 kapplikators. While these lobes are still quite flexible in the circumferential direction, they are clearly more rigid in the direction parallel to the applicator longitudinal axis L on their own than the fingers 4 or bristles of the two previously described
- Embodiments For the surface elements 5, which connect these tabs as well as the fingers 4 in the two embodiments described above, but as above, the above applies.
- the surface elements 5 are usually designed as a membrane or plastic film, which in turn behaves as has already been described above for the first embodiment.
- the stocking not only consists of such fingers 4, but in addition also usually arranged in rows more Fingers 4 * in the form of bristles in the sense defined above.
- this modification also applies to the two embodiments described above. It is merely that such a modification is of little less use (but not useless) in those embodiments.
- the fingers 4 which follow one another in alignment along the longitudinal axis of the applicator L are varied in their length so that they become shorter and longer in alternation, so that a wave results.
- the local loading is varied with cosmetics, in particular mascara.
- the wave troughs are stripped off more strongly and thus more freed from the cosmetics mass initially being charged, in particular mascara mass, than the wave peaks, that is to say the areas in which the fingers 4 have a greater length, in particular a relatively large length.
- flap-like fingers 4 are used as here, which are additionally stabilized by surface elements 5, which connect them with each other.
- a last, alternative fourth embodiment show the figures 9 and 10.
- the fingers 4 are again designed as preferably radially outwardly tapering lobes, but now even more extreme than in the preceding third embodiment. Because here it is so that the lobes in their foot in the direction of the Applikatorlfitsachse L at least by a factor of 5 greater extent than in the circumferential direction of the Ko sme ti kapplikators 1.
- the surface elements 5 are also carried out here as a rule as a membrane or plastic film, which behaves as described.
