  • the cross-sectional area Q which is stressed by a core, is understood to mean the area which encloses the imaginary rope line of a rope, which is wound around the core, bypassing the bristles.
  • the central body 8 in this first embodiment consists of a tube 12, which is shown in black colored in the cross section shown in FIG.
  • the tube 12 is made of a first plastic material and it is initially hollow in the course of the preparation of the applicator.
  • the tube 12 is filled by the second plastic material that has been injected into the tube during manufacture.
  • the two plastic materials are welded where they meet.
  • the second plastic material is more flexible, or more elastic, than the first plastic material.
  • the production is preferably carried out so that first the tube 12 is made with a completely self-contained tube shell.
  • the tube 12 is in an injection mold. This forms on the outer circumference of the tube 12 a plurality of first mold cavities and for each trainees leg a second, the respective tavern 13 a, and 3b and its bristles 6 forming mold cavity.
  • the tube 12 is thus provided with first openings through which the bristles are in communication with the plastic body, which fills the interior of the tube 12.
  • the tube 12 is provided per leg with at least one second opening, through which the legs 3a, 3b is in communication with the plastic body, which fills the interior of the tube 12.
  • the tube 12 can also be provided from the outset with the second opening (s), so that the second plastic mass does not depend on itself for the purpose of shooting into the cavity forming the wing Path through the wall of the pipe.
  • the tube 12 of the first, stronger plastic very easily gives the applicator the necessary resistance to bending moments acting around the applicator longitudinal axis and trying to bend the central body 8 of the core like a rod.
  • the second, less rigid plastic gives the bristles 6 and the at least one leg their required flexibility.
  • the legs 3a, 3b preferably each have a strip-like shape, which usually has two large side surfaces, two small side surfaces and two smaller end surfaces each, wherein the attachment of the respective leg to the central body 8 along one of the two small side surfaces of the leg or along an edge between a small and a large side surface of the leg takes place. It can therefore be said that each leg protrudes in the manner of a wing from the central portion, wherein the wing and the central portion extend parallel to each other.
  • the cross section of a leg 3a, or 3b perpendicular to the longitudinal axis L of the applicator is preferably rectangular or wedge-shaped, so that the leg tapers towards its narrow side facing away from the central portion.
  • the legs 3a, 3b outside of their thin spot 11 are preferably substantially rigid in itself.
  • the legs 3a, 3b extend in the direction of the longitudinal axis L of the applicator, preferably over the entire applicator region, d. H. over the entire bristle-occupied area.
  • the bristles are arranged on the side facing away from the central body 8 side of the leg so that their bristle axes diverge in a plane perpendicular to the longitudinal axis L of the applicator.
  • the bristle tips of adjacent bristles are farther apart than the bristle roots.
  • the legs 3a, 3b themselves have no direct connection with the coupling portion 5, since such a direct connection would hinder their mobility.
  • the legs 3a, 3b form with the central body 8 preferably a V-shaped or acute-angled gap 9, can be stored in the cosmetic mass, the withdrawal of the applicator by the scraper and / or the bottleneck partially to the outside is pushed out and then available in the vicinity of the bristle trim.
  • the central body 8 carries on its outer side preferably at least 80 bristles 6.
  • Each of the legs carries on its outside a bristle stocking of a plurality of bristles 6, namely ideally at least 40 bristles.
  • the central portion may have a round or, better, a polygonal cross-section perpendicular to the longitudinal axis of the applicator. Most effective is its interaction with the legs, however, if it gives him a lemon-like cross-section, ideally so that each leg can create when high forces against a only slightly curved or even straight peripheral portion of the central body 8, the rule itself no bristles having.
  • FIGS. 21 and 22 show a further embodiment of the applicator according to the invention.
  • This further embodiment of the invention differs from the embodiment just described only in that it is a so-called 1-K applicator, which is made of a single plastic, and usually in a single shot, by injection molding.
  • FIG. 22 once again illustrates the mobility of the legs 3a, 3b, which has already been mentioned in the context of the description of the preceding exemplary embodiment.
  • Figs. 23 to 27 show another embodiment of the invention. Also applies to this further embodiment, the above for the vorvorherige embodiment said mutatis mutandis, as far as not otherwise results from the differences described below.
  • a tube 12 is produced in a first step, the i. d. R. integrally into a coupling section 5, which also serves the already described purpose.
  • This tube looks like Fig. 23 illustrates.
  • the tube 12 used for this embodiment preferably has a diamond-shaped cross-section. It is expediently made of a first plastic.
  • this tube 12 differs from the tube 12 used for the above embodiment in that it has from the outset of the material of the tube existing prongs 10 ', which form a comb (comb teeth). If the tube 12 is diamond-shaped, the comb teeth are preferably formed at one or both acute-angled ends of the tube 12.
  • the procedure is preferably such that the initially hollow inner region of the tube 12 is sprayed with a second plastic.
  • the second plastic breaks through in the manner already described, the wall of the tube, at least locally, at one or more locations. He can thereby einsch manen in the mold cavity, which lies behind the outer circumference of the tube and which forms the respective wing and its bristle row, or its bristle field, which preferably consists of several parallel in the direction of the Applikatorl horrsachse rows of bristles 6. It is particularly preferred if a wing at its end remote from the central body 8 forms a number of further comb teeth 10 ', as can be seen with reference to FIG.
  • the wall of the tube from the outset with one or more holes, or openings are provided through which the second plastic material can enter into each of the wing and its bristles forming cavity, as already described in connection with the first use a tube 12 using embodiment.
  • the second plastic is a plastic that is more elastic than the first plastic, as already described above.
  • each of the legs 3a, 3b is provided with a thin spot 11 which forms a kind of hinge around each of the legs, under the influence of the application occurring during the application Forces, towards the central body 8 can shift.
  • the thin spot 11 extends, in the direction parallel to the longitudinal axis L of the applicator, along the entire respective legs 3a, 3b.
  • a cosmetic applicator with a core and bristles protruding outwards which is characterized in that the core is at least partially flexurally elastic such that the cross-sectional area claimed by the core passes through the scraper and / or the neck the cosmetics reservoir associated with the cosmetic applicator is reversibly reduced under the influence of the forces exerted by the scraper and / or the neck of the cosmetic reservoir on the core forces.
  • an applicator is provided which has a core which as such (not only its bristles) at least partially yields, so that its overall diameter decreases, while the core is pulled through the wiper and or the neck of the cosmetic reservoir.
  • the core is folded when passing the scraper and / or the neck of the bottle, and immediately after passing through the Scraper and / or the bottleneck unfolds again to its original size.
  • independent protection is claimed, regardless of the original claims.
  • the core is designed so that it folds, even before the force applied by the scraper and / or bottleneck when pulling / pushing back on the applicator forces are so large that the bristles threaten to take damage.
  • applicators can be built with a core having an enlarged diameter, without at the same time also a new reservoir and / or a new scraper must be provided, both of which have an equally enlarged diameter.
  • a cosmetic applicator consisting of a slotted tube, as shown in Figs. 1-4, and having one or more design details as described above for this type of applicator and which is only intended to be understood by those skilled in the art Applicators of this type heretofore described differ that its slotted tube does not deform or substantially deform under the influence of the forces involved in the application, including withdrawal from the reservoir.
  • a cosmetic applicator consisting of a central body 9 with legs (3a, 3b, 3c, 3d) projecting therefrom, as shown in Figs. 7 to 27 and having one or more construction details as above have been described for this type of applicator and that only differs from the applicators of this type described so far, that its legs under the influence of the forces occurring in the application including the withdrawal from the reservoir not or not substantially move (ie apart from the each body inherent certain elastic deformation under load of less than 5/10 mm).
