Definitions
- the invention has for its object, on the one hand to provide an applicator, which is characterized by a particularly good mass storage capacity and on the other hand, but also allows an exceptionally gentle application experience.
- an applicator consisting of clamped filaments held between at least two wires twisted together.
- a filament usually forms two bristles.
- the bristle is in each case the part of a filament which extends from the nip between the wires twisted together to the radially outer free end.
- a TPE is used for the bristle-forming filaments.
- the elastomers from the group of TPE are characterized by their particular conformability. It is ensured that within the TPE a particularly soft material is used, namely a material having a hardness of less than 60 Shore D and ideally of d 55 Shore D, ideally with max. 1% tolerance.
- the smallest Shore hardness still possible within the scope of the invention is 40 Shore D and, in exceptional cases, 35 Shore D.
- such a material would be of only limited use for the production of bristle-forming filaments because it is actually too soft to produce bristle-forming filaments which subsequently result in bristles of sufficient flexural resistance.
- ribs are provided, which protrude on all sides radially outward from the solid core cross-section of the bristle-forming filament. Grooves are formed between the ribs, which are characterized by a particularly high mass storage capacity.
- the bristles according to the invention must, as far as the specific dimensioning, each quite right on the customized individual case of use, as is gone with the choice of material and geometric design according to the invention in a range that is no longer arbitrarily tolerant with respect to each other closely interacting length and thickness parameters.
- the outer diameter of the filaments should be at least 0.7 mm in undisturbed place. In many cases, it is not favorable if the outer diameter of the filaments is more than 0.9 mm. Smaller diameters are unsuitable for the treatment of the principal hair, which is usually somewhat resistive, as they make the bristles sensitive to kinking.
- the length of the bristles formed by these filaments should not be more than 12 mm for an eyebrow applicator as measured by clamping wire core
- the bristles are at least 5 mm long.
- FIG. 4 shows an enlarged detail from FIG. 3, cut out in the 11 o'clock position.
- FIG. 5 shows a filament according to the invention with a straight end and a cross section (perpendicular to the filament longitudinal axis FL), as shown in FIGS. 2 and 3.
- FIG. 6 shows a filament according to the invention with a pent roof-like end and a cross-section (perpendicular to the filament longitudinal axis FL), as shown in FIGS. 2 and 3.
- FIG. 8 shows a filament according to the invention with a pyramidal end and a cross section (perpendicular to the filament longitudinal axis FL), as shown in FIGS. 2 and 3.
- FIG. 9 shows a section of a cross-section of a filament with flat grooves.
- FIG. 10 shows a detail of a cross-section of a filament with medium-deep grooves.
- FIG. 11 shows a detail of a cross section of a filament with deep grooves.
- FIG. 1 A first overview of an applicator 1 according to the invention in the form of a mascara applicator is given in FIG. 1.
- This mascara applicator consists of a core 2, which in turn has been made from at least two wires twisted together in a spiral.
- the core 2 specifies an applicator longitudinal axis L.
- a number of bristle-forming filaments 5 (compare Fig. 5) have been inserted between the two wires 3 and 4. These are then kept clamped by the twisting between the two wires 3 and 4.
- Each filament 5 forms two bristles 6 which protrude in different directions from the core 2.
- the quality of the mascara applicator which can not be seen in more detail with reference to FIG. 1, consists (predominantly, essentially or completely) of bristles in the form of the filaments according to the invention.
- the said, specially shaped bristle-forming filaments have a filament longitudinal axis FL. They are shown as such - in various variants - in the context of Figures 5, 6, 7 and 8 in the drawing. However, the respective image of the filament in the direction of its filament longitudinal axis FL is strongly "compressed".
- the cross section according to the invention of a bristle-forming filament 5 to be used according to the invention is shown in FIG. 2.
- bristle-forming core are at least eight and in the present case ten ribs 8 in the radial direction to the outside.
- the ribs 8 are on all sides to the outside relative to the filament longitudinal axis FL, which generally forms the center. This means that preferably at each point of the outer shell of the core there is a rib 8 which projects radially outward, as shown in FIG.
- the adjacent ribs 8 meet where the cross section merges into the said solid core 7.
- each of the ribs 8 is designed to run continuously in the direction of the longitudinal axis FL of the respective bristle-forming filament 5, ie has no or substantially no interruption.
- Head / head hair DAmax less than 0.90 and greater than 0.50 / DKmax less than 0.70
- the bristle-forming filament according to the invention preferably consists of a thermoplastic elastomer, that is to say of an elastomer from the family of TPEs.
- Thermoplastic elastomers are characterized by being particularly soft and yielding. This gives the bristles 6, through the bristle-forming between the wires 3, 4 clamped
- Filaments 5 are formed, a particularly good conformability.
- the invention provides that a comparatively large bristle outer diameter is realized, as already stated numerically above for a mascara applicator and also later defined for eyebrow applicators and main hairbrushes.
- the substance stored in these grooves 9 is released - usually stepwise - only when the bristle formed by the respective filament bends back and forth several times in contact with the surface to be treated or the hair to be treated, thereby causing the substance to escape Area of grooves 9 is pushed out.
- the storage effect according to the invention is further enhanced by the fact that the ribs 8, viewed in the circumferential direction, have a width which changes in the radial direction.
- the tip portion 11 of the ribs 8 of the invention - as far as one moves in the radial direction outwardly from the transition base portion / tip portion in the circumferential direction - far predominantly (more than 50%, better more than 75%) has a greater extent EU1 , as the transition between the base portion and the tip portion of the rib in question, whose extent in the circumferential direction is only EU2, see. Fig. 4.
- two ribs 8 which are immediately adjacent in the circumferential direction, form a groove 9 between them, the width of which progressively decreases progressively in the radial direction from the inside to the outside.
- the holding effect is enhanced, which provides the relevant groove 9 of the substance to be applied.
- Groove 9 between two circumferentially immediately adjacent ribs 8 in the direction along the filament longitudinal axis FL preferably extends completely in a straight line.
- the applicators according to the invention preferably characterized in that the number of pinched per turn of its wire core filaments is relatively low. It is predominantly or in all turns between 3 and 15 filaments per turn.
- Reconstruction assets also known as bend recovery assets. They are physically different (namely, in terms of their sub-macroscopic structure) and therefore clearly superior to sprayed bristles.
- the filaments used according to the invention for bristle formation consist of pure TPE.
- TPEs which are particularly preferably used are the subgroups TPE-A and TPE-S which, on the one hand, can be extruded particularly well with the dimensional stability required here and, on the other hand, have a superior bend-recovery capability, which is a material for the production of bristle-forming filaments an essential feature is.
- the material of the bristle-forming filaments according to the invention is always chosen so that it has a hardness which is below 60 Shore D and ideally at d 55 Shore D, plus any tolerance values, as already mentioned above.
- the bristles are usually fed for this purpose a grinding wheel.
- all or a majority of the bristles receive a simple, one-dimensional bevel, which at their free end is a pent roof-like Chamfer 13 gives, which illustrates Fig. 6 in more detail.
- the third embodiment is a main hair applicator.
- the figures also apply. The only difference is that the already specified, required for the main hair application parameters of the filament or
- the tip portion 11 of each or the majority of the ribs 8 is circular in cross-section, as will be apparent from the figures explained below.
- the depth of the groove 9 should be such that the groove 9 is carried out so deep that the circle with diameter DKmax, which forms the shell of the solid core 2 and the circles inscribed in the tip sections 11 with the radius r still affect, see.
- Fig. 9 which shows a relatively small depth for this application, in which the said circles intersect and Fig. 10, which shows the maximum depth for this application, since the said circles are only tangent.
- DKmax is the radius belonging to the maximum diameter of the core 2.
- the depth of the groove 9 should be such that the groove 9 is made at least so deep that the circle forming the shell of the solid Kerns 2 forms and the circles inscribed in the tip sections 11 still affect or the depth of the groove should be made larger, so that the said circles are no longer tangent (and certainly not cut), see. Fig. 11.
- the depth of the groove 9 should be such that that the groove 9 is always made so deep that the circle which forms the envelope of the solid core 2 and no longer affect the circles inscribed in the tip sections 11 (and certainly do not intersect), cf. again Fig. 11.
