EP1108377B1 - Mascara brush - Google Patents

Description

The invention is directed to a mascara brush, wherein a plurality of bristles between two twisted wire sections on either side of this projecting is set, and wherein the bristles have a non-circular cross-section exhibit.

It is known in clover brushes in cross-cloverleaf fibers or fibers having at least one longitudinal capillary groove use this way to create capillary spaces to increase the uptake of and to create transfer capabilities for mascara mass. Furthermore is it has been described, round fibers of different cross-section use.

To obtain brushes with particularly fine fibers on the finished product, which are difficult to process due to their small thickness It has also become known to put together fibers from individual sectors, so that overall a round cross section during the production of the brush results. Once the fibers between the twisted wires are fixed, using a solvent of the Composite of the individual sectors dissolved, so that then this individual Sectors are obtained as bristles of very small cross-section, wherein extending these bristles in a conical way from one and the same point, at which the originally round fiber between the wire sections was squeezed (see DE 92 02 508 U1).

On this basis, the invention is based on the object, a mascara brush to design or a bristle for a mascara brush to create an optimal combing and transfer behavior to realize.

This object is achieved in that starting from initially in a conventional manner extruded fibers at least two Such fibers in the longitudinal direction linear or punctiform with each other are connected.

This makes it possible to almost any cross-sectional configurations especially if you have the option in another variant Consider pulling together fibers of different diameters. The bristles thus created have in particular a high capillarity on.

The fibers can either be continuous linear in the longitudinal direction be connected to each other. Alternatively, however, it can also be provided that the fibers are connected only punctiform, conveniently In addition, it can be provided that at least one fiber is not parallel to a respective other fiber runs, but approximately wave-shaped, wherein punctiform connections then made only in the troughs become. This ensures that between two such fibers small, elongated eyelets form, in which mascara mass retained can be.

Furthermore, it can be provided that at least a part of the fibers as Hollow fibers or is formed with a non-circular cross-section.

The inventive design is also a spreading effect and Achieved a uniform peak distribution.

The connection of the fibers with each other can with all in the plastic technology customary connection techniques are accomplished, in particular thermal, chemical, ultrasonic welding, etc.

a representation corresponding to FIG. 6 with three connected fibers.

In the embodiment illustrated in FIGS. 1 and 2, a first fiber is 1 larger diameter with a second fiber 2 smaller diameter connected along a line 3, on both sides of this line 3 capillary Troughs 4, 5 are formed.

In the embodiment of Figs. 3 and 4, a central fiber 1 is larger Diameter with three fibers 2 smaller diameter connected.

From the cross-sectional view of FIG. 5 it can be seen that a central Hollow fiber 6 larger cross-section with two diametrically opposed full fibers 2 smaller cross-section is connected.

Figs. 6 and 7 show examples where each one or two fibers 2 small Cross section with a thicker fiber 1 only at discrete welds 7 is connected, wherein the thinner fiber 2 each formed wavy is, so that between two successive welds. 7 eyelet-like spaces 8 are formed, which create a capillary reserve allow.
