The invention relates to the domain of fluid or paste product applicator devices, typically cosmetic applicators such as mascaras.
Many mascara applicators are already known.
These applicators are designed to cooperate with a receptacle forming a reservoir for mascara, and typically comprise:
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.
Very many different brushes are already known.
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, FR 2,701,198, FR 2,706,749, FR 2,715,038, FR 2,745,481, FR 2,748,913, FR 2,749,489, FR 2,749,490, FR 2,753,614, FR 2,755,693, FR 2,774,269, FR 2,796,531, FR 2,796,532, FR 2,800,586 are known.

Problems That Arise
Firstly, to satisfy continuing changes to mascara formulas, it has been necessary to develop new applicators for application of these formulas, typically adapted to each new formula.
Secondly, there is also a need for users to have a wide range of applicators to obtain different effects, for example different filling ratios of the product to be applied in the applicator, and/or different eyelash curving effects.
It is also becoming increasingly necessary to obtain economic and preferably recyclable products, otherwise the corresponding production facilities may be delocalized in countries with low labour costs.
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.
According to the invention, the applicator device (1) for a paste product, typically a cosmetic, and typically intended to cooperate with a receptacle containing the said paste product, contains a longitudinal body with an axial direction, the said longitudinal body including an axial rod and an applicator fixed to the said axial rod, the said rod being intended to cooperate with a manual gripping means of the said applicator device, the said applicator being capable of sampling a fraction of the said product contained in the said receptacle, typically by cooperation of the said applicator with a wiper, so that it can be applied on a support, usually consisting of a part of the body or the face when the said product is a cosmetic, and is characterized in that:
In general, the L/D shape factor will vary from to 3 to 6.
This combination of means provides a means of solving all problems that arise.
The applicator device according to the invention can be adapted to any type of mascara formulation or any other product sampled by dipping then wiping, particularly by varying the geometry of the said radial discontinuities.
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.
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.

In this case, the said plurality of elements may be formed by an axial sequence of elements in relief (7′), typically spheres (77), the said spheres (77) typically adjacent and having a variable diameter in the case in which the said applicator forms a spindle.
As illustrated in
The said strip (83, 83′) may act as a support for a plurality of elements in relief (830) and for the cavities (831), the said cavities (831) opening up on the said inner space (84).
The said applicator (4) may comprise a central axial arm (85) designed to partially fill the said axial space (82) so as to limit the quantity of the said product that cannot be transferred onto the said support during the said application.
As illustrated in
The said plurality (7) of elements in relief (7′) may be formed by at least a plurality of transverse projections (76), typically arranged symmetrically on each side of the said axial rod portion (86) and aligned along the same axial plane containing the said axial direction (20), the said transverse projections (76) forming a plurality of transverse recesses (65) combining to form the said contact surface S with the said product and the said retention volume V of the said product, each transverse recess (65) being formed by a spacing between two adjacent projections (76).
As illustrated particularly in FIG, 11g, the said plurality (7) of elements in relief (7′) may be formed by two pluralities P1 and P2 of transverse projections (76), the said transverse projections (76) of each plurality P1 and P2 typically being arranged symmetrically on each side of the said axial rod portion (86) and aligned along the same axial plane containing the said axial direction (20), the said pluralities P1 and P2 forming an acute angle a typically less than 70°, and possibly a complementary acute angle β typically greater than 110°, such that the said adjacent portions forming the said acute angle α between them form a dihedron retaining the said product, such that the said adjacent projections forming the said complementary acute angle β between them form a comb for eye lashes during the said application.
The said pluralities P1 and P2 may form a plurality of four concurrent projections or “X”-shaped teeth in a plane perpendicular to the said axial direction (20), two successive teeth of a said plurality having a transverse recess (65) contributing to forming the said contact surface S with the said product and the said retention volume V of the said product, two concurrent teeth forming the said angle α between them thus also contributing to forming the said contact surface S with the said product and the said retention volume V of the said product.
As shown in
According to the invention, the said single piece part (4′) made of a plastic material forming the said applicator (4) may be a molded part made of only one plastic material.

As illustrated on all the figures, the said axial rod (3) and the said applicator (4) form a longitudinal body (2′) made of a molded single piece part (2′) formed of only one or several plastic materials.
As illustrated in
Typically, the axial length of the said axial rod (3) may vary from 20 mm to 70 mm so as to cooperate directly or indirectly with the said cap by means of the said head (21).
According to one variant of the invention, the said axial rod (3) may include a rigid part and a flexible part, the said flexible part typically having a section at least half the size of the said rigid part, so that the said axial rod (3) bends during the said application.
All figures form example embodiments.
The eleven different embodiments were molded, each embodiment corresponding to one of plates 1 to 11 in the figures.
Firstly, a single piece parts (2″) were molded forming the said longitudinal bodies made of a single plastic material. The tests were carried out using PP and POM.
Single piece parts (2″) in which the central part forming the support (8) was made of modified PP were also fabricated, with the said plurality (7) of elements in relief (7′) being made of an elastomer.
Some single piece parts (2″) made entirely of elastomer were also made.
The applicator devices (1), after dipping in a cosmetic formula, could be used for application on the body (eye lashes, lips or any other part of the body depending on the product considered).
Bodies (2) were made with axial rods (3) with a cylindrical, oval, square or twisted section, and applicators (4) with a length L varying from 14 mm to 26 mm and a width or largest transverse dimension D varying from 3 mm to 6 mm.
Results Obtained
The applicators (4) and applicator devices (1) according to the invention offer a very wide variety of embodiments such that they can be adapted to different types of supports, eye lashes being the support for mascara formulas, and to different types of formulas in which the viscosity and concentration of the solid product can vary, and that can be adapted to achieve the required effect (increased volume, curving or increasing the length of eye lashes in the case of mascara), and several effects can be obtained with applicators according to the invention, and particularly with applicators according to
