Abstract

The wiper (1) intended to engage with a neck of a container intended to contain a fluid or paste cosmetic product includes a body (2) intended to be anchored to the neck, and a wiping element (3) anchored to the body (2). The wiping element (3) includes a resilient wall (4) which anchors the wiping element (3) to the body (2), the resilient wall (4) being able to distort when the applicator passes through, and to resume its so-called at rest shape after it has passed. The wiping element (3) includes a plurality of N typically vertical radial tongues (5) independent of each other, with N typically being between 4 and 20, typically integral with a peripheral skirt (6) of the wiping element (3).

Claims

1. Wiper (1) intended to engage with a neck of a container intended to contain a fluid or paste cosmetic product, typically a mascara, including a typically annular body (2) intended to be anchored to said neck, said body (2) and said neck having one and the same axial direction (10), and a wiping means (3) anchored to said body (2), said wiping means (3) being intended to engage with said applicator, each time the applicator passes through, particularly each time an applicator-device fitted with an applicator, typically a brush, is withdrawn and separated from said container, so as to restrict, to a pre-set level, the quantity of said cosmetic product taken out, and is characterised in that:

a) said wiping means (3) includes a resilient wall (4) which anchors said wiping means (3) to said body (2), said resilient wall (4) being able to distort when said applicator passes, and to resume its so-called at rest shape after it has passed,

b) said wiping means (3) includes a plurality of N typically vertical radial tongues (5) independent of each other, with N typically being between 4 and 20, typically integral with a peripheral skirt (6) of said wiping means (3).

2. Wiper according to claim 1 wherein said resilient wall (4) includes a thinned part (40) able to form a hinge for tilting said wiping means (3) relative to said body (2).

3. Wiper according to claim 1 wherein said resilient wall (4), via its upper end (42), is integral with said wiping means (3) in its upper part (30), and, via its lower end (43), is integral with said body (2) in its lower part (21).

4. Wiper according to claim 1 wherein said resilient wall (4) includes a central part forming a cylindrical portion (41) centred along said axial direction (10), said cylindrical portion (41) being separated from said body (2) by an external annular channel (11) and being separated from said radial tongues (5) by an internal annular channel (12).

5. Wiper according to claim 4 wherein said external annular channel (11) forms an upturned annular trough of radial thickness Ee between 0.5 mm and 2.5 mm, and wherein said internal annular channel (12) forms a down-turned annular trough of radial thickness Ei between 0.5 mm and 2.5 mm.

6. Wiper according to claim 1 wherein said N radial tongues (5) are typically identical and spaced out angularly around said axial direction (10) by an angle equal to 360°

/N, with N preferably being between 6 and 18, so as to form a plurality of radial channels, two adjacent radial tongues forming between them a radial channel.

7. Wiper according to claim 6 wherein said radial tongue (5) is a vertical tongue (7), and wherein said radial channel is a vertical channel (70).

8. Wiper according to claim 7 wherein said vertical tongue (7) has a central edge (75) contained in a vertical plane containing said axial direction (10).

9. Wiper according to claim 7 wherein said vertical tongue (7) has a central edge (75) contained in a vertical plane located at a constant distance d from said axial direction (10).

10. Wiper according to claim 7 wherein said vertical tongue (7) has, in a horizontal plane (13) perpendicular to said axial direction (10), a section in the form of an angular sector with an apex angle α

between 0.9×

360°

/N and 1.1×

360°

/N, said vertical tongue (7) including two vertical faces (73) forming a dihedral angle with apex angle α

.

11. Wiper according to claim 7 wherein said wiping means, forming a plurality of vertical tongues (7), has an internal envelope volume, delimited by the internal profile (71) of said tongues, typically including, from top to bottom:

a) a flared upper part (710), opening upwards and typically like a truncated cone, with a maximum diameter Dh

b) a central part (711), typically cylindrical, with a diameter Dc

c) a flared lower part (712) opening downwards, including a cylindrical lower end (713), with a diameter Db.

12. Wiper according to claim 11 wherein Dc is between 3 mm and 6 mm, with Dh/Dc between 1.2 and 3.5 and Db/Dc between 1.2 and 3.5.

13. Wiper according to claim 7 wherein said vertical tongues (7) have a height H_L between 2 mm and 10 mm.

14. Wiper according to claim 6 wherein said plurality of vertical tongues (7) is integral with said typically cylindrical peripheral skirt (6), each vertical tongue (7) being integral by its base (72) with said peripheral skirt (6), said peripheral skirt (6) limiting, at their periphery, said radial channels (70).

15. Wiper according to claim 7 wherein the totality or a fraction of said vertical tongues (7) includes, typically on each of its two vertical faces (73), and over a small part of its height H_L, typically over a height between 0.1.H_L and 0.2.H_L a lateral projection forming an additional wiping platelet (74).

16. Wiper according to claim 15 wherein said additional wiping platelet (74) has a horizontal profile widening as it moves away from said axial direction, in such a way that said radial channel (70), included between two vertical tongues gets gradually smaller, said radial channel (70) being considered at the level of said wiping platelet (74).

17. Wiper according to claim 15 wherein said wiping platelet (74) has a typically horizontal lower surface (740) and an inclined upper surface (741), said lower and upper surfaces connecting through a wiping edge (742), in such a way that said lower surface (740) participates in said wiping when said applicator is withdrawn from said container, and in such a way that said upper face (741) facilitates the return of said applicator into said container.

18. Wiper according to claim 15 wherein each vertical tongue (7) has a wiping platelet (74) on each of its right-hand and left-hand vertical faces (73), said wiping platelets (74) being typically at the same height, a so-called right-hand wiping platelet (74′

) on said right-hand face and a left-hand platelet (74″

) on said left-hand surface, said right-hand wiping platelet (74′

) of a vertical tongue and said left-hand wiping platelet (74″
