Applicator device for paste products, typically cosmetics

Abstract

Applicator device (1) for a paste product, typically a cosmetic, typically intended to cooperate with a receptacle containing the paste product, contains a longitudinal body (2) with an axial direction (20), the longitudinal body (2) including an axial rod (3) and an applicator (4) fixed to the axial rod (3). The axial rod (3) is intended to cooperate with a manual gripping means of the applicator device (1), the applicator (4) is capable of sampling a fraction of the product contained in the receptacle, typically by cooperation of the applicator with a wiper, so that it can be applied on a support, usually a part of the body or the face when the product is a cosmetic. The applicator (4) forms a single piece plastic part (4′), typically a molded part made of one or several plastic materials, has a shape factor L / D varying from 2 to 7, where L is the axial length and D is the maximum radial diameter of the applicator (4) or a surrounding volume (40) of the applicator, the axial length L is between 10 and 20 mm, the applicator includes a support (8) and a plurality (5) of radial discontinuities (5′) fixed to the support (8), the plurality of radial discontinuities (5) forming a plurality (6) of cavities and / or a plurality (7) of elements in relief (7′) such that the device offers a high contact surface area S with the product and a high retention volume V of the product.

Description

FIELD OF THE INVENTION [0001] The invention relates to the domain of fluid or paste product applicator devices, typically cosmetic applicators such as mascaras. STATE OF THE ART [0002] Many mascara applicators are already known. [0003] These applicators are designed to cooperate with a receptacle forming a reservoir for mascara, and typically comprise: [0004] a) a cap that will close off the said receptacle and act as a gripping means for the said applicator, [0005] b) an axial rod, [0006] c) and a brush, [0007] the said rod being fixed to the said cap at one of its ends, and to the said brush at the other of its ends, the said brush including a twisted metal wire fixing several bristles. [0008] Very many different brushes are already known. [0009] Thus, brushes described in French patents FR 2 505 633, FR 2,605,505, FR 2,607,372, FR 2,607,373, FR 2,627,068, FR 2,627,363, FR 2,637,471, FR 2,637,472, FR 2,650,162, FR 2,663,826, FR,2,668,905, FR,2 675,355, FR 2,685,859, FR 2,690,318, ...

AI Technical Summary

Benefits of technology

[0023] Compared with a traditional mascara brush, the applicator device according to the invention has the advantage that it includes a single piece applicator formed by a moulded part made of one or several plastic materials which makes high speed automatic production of the said applicators or the said longitudinal bodies possible.

[0024] Thus, it is no longer necessary to assemble a fibre layer with a twisted metal wire, and then to assemble the end of the said twisted metal wire to a rod, itself fixed to a cap.

Problems solved by technology

Finally, in the cosmetics field, there is an ongoing demand for new products, particularly to personalize products in terms of formulas, applicators or even packagings in general, to the extent that renewal of products becomes an absolute commercial necessity, otherwise the market may be lost.
