1. Field of the Invention
The invention relates to a mascara brush comprising a plurality of bristles which stand out radially and are held between two intertwisted wires, the tips of the bristles having varying lengths in such a way that envelope sections formed by the bristle tips are put into practice which, seen in the circumferential direction, lie radially further outwards and radially further inwards.
2. Background Art
EP 1 050 236 teaches a brush of the generic type, comprising sections of longer bristles that are wider in the circumferential direction and sections of shorter bristles that are distinctly shorter in the circumferential direction, both forming a convex envelope.
DE 37 35 963 C2 also describes a mascara brush, the trimming of which includes concavely cut depressions so that a kind of comb of short length in the circumferential direction is produced between two such adjacent cuts.
Mascara brushes of the generic type are required to offer excellent properties of transfer from the reservoir to lashes on the one hand and optimal application and separation of the lashes on the other, which is what the two above documents proceed from.
It is an object of the invention to obtain a solution, complying optimally with those requirements that are fundamentally known.
According to the invention, this object is attained by the envelope sections of longer bristles being shorter in the circumferential direction than the envelope sections formed by shorter bristles; by the envelopes being convex; and by the length of the shorter bristles growing progressively in the circumferential direction, corresponding to the radius of curvature of the associated envelope.
The bristles of varying length and the resulting, varying effective rigidity help attain uniform application on to the lashes on the one hand and a combing and separating effect on the other, which to this extent has been known per se.
The progressive increase in length, according to the invention, of the shorter bristles will optimize the procedure of application, with a user turning the brush upon application, which simultaneously works in favor of the so-called curl effect, bending the lashes attractively.
In keeping with the invention, provision is made for transition by steps between the envelope sections of longer and shorter bristles.
In particular provision is made for a plurality of preferably three envelope sections of longer and shorter bristles.
By advantage, the free end of the trimming of bristles may taper conically in the axial direction.
Details of the invention will become apparent from the ensuing description of an exemplary embodiment, taken in conjunction with the drawing.
A mascara brush seen in the drawing comprises a core 1 of wire bent in the shape of a U, the two legs of which on either side of the bight of the U being intertwisted, fixing the bristles 2. In this way a trimming is formed over a length L, the free part 3 of the core 1 constituting a handle.
As seen in
The envelope sections 5 of longer bristles 2a are shorter in the circumferential direction, covering a smaller angular area than the envelope sections 6 of shorter bristles 2b. The envelope sections 5 pass by steps 7 into the envelope sections 6. In the exemplary embodiment, three envelope sections 5 are formed by longer bristles 2a and three envelope sections 6 are formed by shorter bristles 2b. One envelope section 5 and one envelope section 6 at a time make 120°, the width of the envelope sections 5 of longer bristles 2a being for example in the range of approximately 3 mm.
Proceeding from a first step 7, the length of the shorter bristles 2b or, respectively, the radius of curvature of the envelope sections 6 increases progressively towards the next step 7 in the direction of the arrow P.
