Description

The The invention relates to a Macara applicator with a handle part, the connected via a support member with a brush is. Moreover, the invention relates to a sales unit for a corresponding mascara applicator.

to Application of mascara, so-called mascara, on the eyelashes of a human, a mascara applicator is known, which has a reservoir, in which the mascara is located, and one provided with a handle part Brush has. The brush is common designed as a so-called wired brush, d. H. between two thin, parallel metal wires Become a variety of commonly made of plastic Filament segments arranged, which are substantially perpendicular extend to the longitudinal direction of the wires. Subsequently The wires are twisted so that the filament segments between the wires are clamped and held and simultaneously be distributed in the circumferential direction, so that a bristle field results in which each filament segment forms two bristles and the Bristles are distributed around the circumference and the twisted ones Wires the rod-shaped core of the brush form. When using the mascara applicator, the user grabs the handle and dips the brush in the reservoir present mascara, these on and between the individual Bristle of the brush gets stuck. When pulling out the brush from the reservoir becomes excessive Mascara stripped and the brush is subsequently brought to the eyelashes and in a combing motion in the longitudinal direction of the eyelashes, whereby the mascara is transferred to the eyelashes becomes.

It is known that it is for the proper Applying the mascara is essential to the eyelashes when applying by means of the brush to separate, about every eyelash over to provide their entire circumference with the mascara. This separation of eyelashes is done with a wired brush not or only in exceptional cases, as a wired Brush due to the uneven over The bristles distributed over the circumference do not have a precisely defined combing effect brings with it. However, can be wired with a Brush a relatively large amount of mascara take up the reservoir and apply to the eyelashes, so that the eyelashes given a so-called large volume can be.

As an alternative to a wired brush, brushes produced using the plastic injection molding process are also known (US Pat. DE 101 02 219 A1 ), the radially protruding fingers made of a soft-elastic plastic, in particular an elastomer, having the fingers are arranged in a predetermined arrangement on the outside of a usually rod-shaped carrier. The dimensions of the individual fingers and their mutual arrangement can be set so that there is a good combing effect and separation of the eyelashes when applying the mascara. The production by injection molding also ensures that the desired geometry is achieved with high accuracy. However, the disadvantage associated with an injection-molded brush is that only a relatively small amount of mascara can be taken up from the storage container and transferred to the eyelashes.

It It has been shown to be consistent Order of the mascara is necessary that the brush as possible exactly to the geometric and structural properties of the eyelashes of the user to whom the mascara is to be applied, and in particular also to the individual order behavior of the user is adjusted. However, since people have different eyelash lengths, Own eyelashes and eyelashes and the mascara also apply in different ways, can with the brush a conventional mascara applicator usually no optimal separation of eyelashes and no optimal mascara application can be achieved because the brush is designed so that they with as many types of eyelashes and user-specific as possible Behavior brings an acceptable result.

Of the Invention is based on the object, a mascara applicator of called type to create different types of eyelashes and / or different order behavior of the user can. In addition, a sales unit for to create a corresponding mascara applicator.

These Task is with respect to the mascara applicator by the features of claim 1. It is envisaged that the Brush is interchangeable held on the support member. by virtue of The interchangeability of the brush allows the user choose the brush from a range of brushes the for his eyelash type and his order behavior at best suited so that each user has one according to individual Wish and needs adapted mascara applicator has available.

Preferably, each brush has a protruding approach, for example, stalk or stiftar tig may be formed and with which the brush in a detachable manner to the support member can be fixed. This can for example be achieved in that the brush is used with the approach in a receptacle of the support member, wherein the receptacle may be formed, for example, tubular or sleeve-shaped. Alternatively, it is also possible to design the approach tubular or sleeve-shaped and set up on a stalk or pin-like projection of the support member.

The mutual fixation between the support member and the brush can be achieved by a catch or a screw connection.

Regarding the sales unit achieves the above-mentioned object by that the sales unit has a mascara applicator of the one described above Kind and additionally a assortment of several brushes has, which are each replaceable attachable to the support member. The user can choose from the variety of brushes for choose the brush type best suited to him and attach in the manner mentioned on the support member or the handle part.

The Brushes can be loose and individual to the sales unit be enclosed, but preferably a holder is provided, the has a plurality of receptacles, wherein in each shot a brush can be inserted or used, so that the brushes in the sales unit has a predetermined mutual orientation and Occupy relative position, which has the advantage that the buyer of the sales unit through a transparent Packing through the individual brushes examine and Accordingly, he can make his purchase decision.

The brushes attached to the sales unit a different structure and / or a different geometry exhibit. Regarding the different structure should at least one of the brushes is a wired brush. If several wired brushes are provided, these can with respect to the bristles per wire turn and / or in terms of their outer diameter and / or in terms of a straight or curved orientation may be different.

Furthermore At least one of the brushes should be injection molded Be a brush. If several in the brush assortment injection molded brushes are present these vary in the number of fingers and / or in terms of the mutual distance of the fingers and / or in terms of Length of the fingers and / or the outer diameter the brush and / or in terms of a straight or curved Differentiate brush orientation.

Around the mascara regardless of the type, the structure and the Geometry of the brush evenly and in Apply enough amount to the eyelashes can, has a special recipe of mascara as made sense, regardless of the in this Registration called mascara applicator can be used.

For The mascara it is essential that they brush with each The brush assortment harmonizes, since only a single Mascara preparation for all contained in the sales unit Brushes is available. For this it is necessary that the Mascara preparation has a thixotropic behavior and - ever on the type of penetrating brush - a different Viscosity sets. A wired brush provides a relatively low resistance to penetration into the mascara there, because the bristles due to the resistance of the mascara to the so-called wire core to be bent. This can be experimentally simulate by measuring the penetration depth into the mascara preparation and characterize. A brush is doing by a Zylin the simulated with an area X, with a low penetration rate pressed into the mascara preparation.

in the In contrast, injection molded brushes provide a relative great resistance there, because the core of the injection molded Brush relatively thick and the fingers are relatively stiff. This corresponds to a relatively high penetration rate in the experimental model of the cylinder with the area X.

at Macara preparations which are in accordance with the application Sales unit are interesting, are at relatively high penetration speeds relatively small forces necessary and at relatively low Penetration speeds higher forces. A high penetration rate simulates a very dense brush, which exerts a great repression when immersed, z. B. an injection molded brush with a compared to Overall diameter relatively thick core. A low penetration rate simulates a brush with a relatively low displacement, z. B. a wire brush with 5 to 15 filaments per wire turn.

In 6 is a diagram of the penetration depth on the penetration or experimental speed shown. A suitable mascara formulation should have a maximum penetration depth at a test or penetration speed in the range of 0 to 0.2 mm / s for a wired brush and a minimum of penetration depth in the range of 0.6 to 1.0 mm / s as it is in 6 is shown. The minimum depth of penetration should be less than or equal to 60% of the maximum depth of penetration.

The Measurements are taken with a device from the company Texture Analyzer TAXT plus, where the measuring cylinder has a diameter of 0.25 inches has and the limit force at which the measurement or penetration in the mascara preparation is finished, at 23 g.

Of the cylindrical gauge penetrates at a rate of 0.10 mm / s in the mascara preparation and the respective reaction force is detected, the measurement being at a reaction force of 23 g is terminated. The penetration depth results from the difference the position at a reaction force of 23 g and the position at a reaction force of 1.5 g and is expressed in mm.

An example of the composition of the mascara for the sales unit according to the application is shown in the following table: Phase A in% by weight Acrylate-octylacrylamide copolymer + water 3.0000 biotin 0.0100 butylene 1.0000 iron oxides 10.0000 Magnesium aluminum silicate 2.0000 panthenol 1.0000 talc 2.0000 triethanolamine 2.4800 water 54.7600 Phase B in% by weight methylparaben 0.3000 stearic acid 6.0000 simethicone 2.0000 cetyl alcohol 1.0000 BHT 0.0500 Phenoxyethanol + methylparaben + ethylparaben + butylparaben + isobutylparaben + propylparaben 0.5000 lanolin 0.4000 carnauba 2.5000 beeswax 5.0000 microcrystalline wax 2.0000 VP-eicosene copolymer 1.0000 candelilla 3.0000

The both phases A and B are prepared independently and then combined with stirring and homogenized.
