Abstract

The invention relates to a mascara brush with bristles bound by twisting in a twin-layer wire core (2), the bristles consisting of multiple fibres (3) bound by means of a solvent-soluble binding agent. Furthermore, the invention relates to a method of manufacture of the mascara brush, wherein the bound multiple-fibre bristles (3) are bound by twisting into the wire core (2) and, subsequently, the binding agent is dissolved out of the multiple fibres with a solvent, the bristles thereby being separated into individual fibres (4). In this way it is possible to obtain a dense array of fibres at the brush surface. <IMAGE>

Description

1 :2:2:d- i-) 1 C1 CES -I- Mascara Brush The invention relates to a

mascara brush with bristles bound by twisting in a twin-layer wire core.

The majority of mascara brushes available on the market are of the construction described above. according to which a flat layer of bristles between two wires generally. in this arrangement. the=e is a single bent back wire - are bound into a spiral brush by the twisting of the wires. This construction is extremely rational and advantageous in price.

2-5 These known masacara brushes, however, with twisted wire core have this drawback that the bristles do not constitute a closed dense surface but, as already stated, are arranged substantially along a spiral helical surface. Therebetween there occur gaps of varying width which are dependent upon the bristle diameter and particularly also upon the coil turn distance of the twisted wire core, If these gaps are too great. which is always the case in terms of the distancep for example, from the eyelashes. the danger occurs that several hairs from the eyelashes will enter such a gap, and then on the application of the mascara will stick together. Thisy of course. must be avoided at all costs.

It is therefore the object of the Invention to design a mascara brush of the type first defined hereinabove in such a manner that with the same simple method of 1 2 construction the bristle ends fill up a dense closed surface.

For the achievement of this object it is provided in conformity with the invention that the bristles consist of multiple bristles bound by a releasable binding agent.

p As a result of the utilisation according to the invention of bound multiple fibres as bristles the bristles can have the normal.easy-toprocess thickness. such as found also In the mascara brushes known hitherto. it Is not till the bristles have been twisted in and the binding in of these bristles has been effected thereby that they are released as individual multiple fibres. while by dipping into a corresponding binding agent the latter is ctleated away. so that the individual thin bristles become free. They then correspondingly spring up, thereby filling the initially existing gaps between the coll turn surfaces more densely taken up by fibres, The danger of the sticking of hairs of the eyelashes jointly entering the gaps is thereby avoided.

As opposed to correspondingly fine fibres which are then seen as the end effect the use of the bound multiple fibres Is advantageous for several reasons. Firstlyt these thin fine fibres which are thus obtained as a final effect. are not bound in in the i 0 1 3 same simple manner into the wire core by twisting. Secondly. in the end, the same difficulty would then occur on twisting, i.e. that the very thin fibres, even though in a greater number. are again in the first place concentrated on the coil turn surfaces. It is not till the splitting apart after twisting in that the springing up leads to the closure of the gaps still remaining at the outset between the turns of the coil.

Furthdr advantagesq characteristics and individual parts of the invention will be found in the following description of an example of embodiment as well as in a consultation of the drawings. wherein:-

Fig. 1 is a side view of a mascara brush of the invention witb fanned out multiple fibres; Fig. 2 is a diagrammatic view intended to clarify the binding in of the multiple fibres before the actual twisting; Fig. 3 is a magnified partial view of the mascara brush to make the fanning out of the multiple fibres clearer. and Fig. 4 is a crosssection through a bound multiple fibre.

rig. 1 shows a mascara brush with a handle 1 of the usual type and a twolayer wire core 2 secured onto it which is formed (cf. Fig. 2) of a bent back single wire. In this wire core 2 the bristles 3 initially laid as a flat cluster between the bent back wire ends are 1 4 bound In by twisting. as a result of which the usual pattern of mascara brushes is obtained, the bristles being distributed in substantially flat fashion on spiral surfaces produced by the rise of the twisting of the wire core 2. There arise as a result correspondingly wide gaps between these coil planes more densely occupied by the fibres 3. with the drawbacks first defined in detail hereInabove. According to the invention the bristles 3 consist of multiple fibres as shown in cross- section in Fig. 4, these multiple fibres being. as a plurality of individual fibres 4. joined by a releasable binding agent to form a multiple fibre bristle. Naturallys in this arrangement. the special sector-shaped cross-section of the individual fibres 4 must not be provided. although this Is surely of advantage in the construction. It is decisive that one should have at the outset. for the binding in of the bristles 3, correspondingly thick fibres which are not split up into the individual fibres 4 after binding in till the brush has been dipped into a solvent which dissolves the b"d.nig. agent out. This subsequent splitting apart is also decisive becausey thereby. as will be seen in Fig. 3. the Individual fibres 4 of a bristle produce a conical spreading apart. so that. In conformity with the final pattern shown in Fig, 1. the individual fibres fill out the gaps between the levels of the turns to a varying degreeg and in any event to such an extent that a sticking of eyelashes having entered between such spiral or turn levels is avoided.

Claims

1. A mascara brush comprising a plurality of fibrous bristles bound by twisting in a twin-layer wire core, wherein the bristles consist of multiple fibres bound together by a soluble binding agent.

2. A method of making a mascara brush comprising a plurality of fibrous bristles bound by twisting in a twinlayer wire core, wherein the bristles consist of multiple fibres bound together by a soluble binding agent, said method comprising binding the bristles with a soluble binding agent, twisting said bristles between the wires of the twin-layer wire coret and dissolving the binding agent to enable separation of the individual fibres of the bristles.
