Embodiment Construction

[0071] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

[0072] Figure 1A shows a brush 1 of square cross-section at a high level. The application portion of the device is numbered 3 . The axis X of the tail 4 of the brush forms an acute angle β with one surface 10 of the brush, the apex of which is directed towards the tail 4 . The axis X of the tail 4 of the brush 1 forms an angle α with the surface 40 of the brush opposite the surface 10 , the apex of which is remote from the tail 4 . The included angles α and β are approximately equal, so surfaces 10 and 40 are approximately parallel. The size of the included angles α and β is about 5°. The other two longitudinal surfaces are not marked, they are parallel to each other and to the axis X of the tail 4 . In the following description, reference numerals beginning with the numeral “1” refer to the surface forming an angle of the type “β” with the axis X and the apex of the angle facing the tail 4 by convention. The numbe...

Abstract

A device for applying a product to keratinous fibers comprises a tail having a longitudinal axis X and an application element extending from an end of the tail. The application element may comprise at least a first face and a second face, each of the faces being delimited by two longitudinal edges and extending over at least part of a length of the application element. The first face may form with the axis X a first non-zero angle alpha having a vertex oriented toward a first end of the application element, and wherein the second face may form with the axis X a second non-zero angle beta having a vertex oriented toward a second end of the application element. The second end of the application element may be opposite to the first end.

Description

technical field [0001] The present invention relates to a device for applying a product to keratin fibers such as eyelashes, eyebrows, beard or hair. This device is particularly suitable for applying cosmetic and / or care products to such fibers, in particular for applying mascara to eyelashes or eyebrows. [0002] In particular, the invention relates to brushes commonly referred to as "twisted brushes" which are formed by placing a bristle sheet between two hairpin-shaped wires and twisting the two wires about their axes. be made of. In this way, the twisted wire forms a helix (actually, each strand of metal wire forms a helix), and according to the twisting direction of the wire, the helix moves from left to right (when viewed from the front of the vertical position). While looking at the brush) rises or rises from right to left. Brushes that can be made by the first type of twisting are sometimes referred to as "left-handed brushes". Such a brush is described inter alia ...
