AI Technical Summary

Problems solved by technology

This removal operation, e.g. by trimming or laser cutting, is complicated to prepare and leads to a reduction in the combing capacity of the brush due to a reduction in the number of bristles and a weakening of the resistance of the remaining bristles, resulting in a shortened service life of the applicator

example

[0077] The brush according to the invention is produced with the following technical features:

[0078] - Hollow fiber with a diameter of 4 mils and a length of 8.5 mm

[0079] - 50 fibers per circle

[0080] - Stainless steel 304L wire, diameter 0.7mm

[0081] - A cluster of 27mm turns 13 times

[0082] -1.1mm extrusion size

[0083] In order to obtain such a brush, a standard type brush is manufactured with the first 4 characteristics mentioned above. The brush was placed in the press between calibrated scales of 1.1 mm height, and the brush was squeezed until the press reached the end of its travel against the calibrated scale. The brush formed in this way comprises two symmetrical grooves relative to the central axis of the brush, said grooves extending in the axial direction, and each groove comprising a scallop angle of approximately 90° without fibers. The helical turn of the brush is elliptical and has a major (-1.6) to minor (1.1) ratio of approximately 1.45. Su...

Abstract

An applicator for a cosmetic product, typically mascara, comprising a brush consisting of fibres trapped between two twisted arms extending in an axial direction and defining turns is characterized in that at least one of the said turns is a turn that is not circular. More particularly, these turns describe noncircular ellipses. Such an applicator can be made by radially crushing a standard brush.

Description

technical field [0001] The present invention relates to the field of applicators for fluid or creamy products, in particular on keratinous fibers, generally cosmetic products such as mascara. Background technique [0002] A large number of mascara applicators are known. [0003] These applicators are designed to fit into the container that forms the container for the mascara and typically include: [0004] a) a cap, which is designed to close the container and is used as a gripping device for the applicator; [0005] b) Shaft; [0006] c) and a coating device. [0007] The applicator or applicator may consist of a brush, one end of the rod is connected to the crown and the other end is connected to the brush, the brush includes a metal strand that binds a plurality of bristles or fibers together. Wire. [0008] With regard to said brushes, a very large number of brushes are already known. [0009] The brushes described in the following French patent texts are known: FR...
