Abstract
An applicator in the axial direction is designed to cooperate with a receptacle provided with a threaded neck and containing a cosmetic product. The applicator comprises: a) a manual gripping means, b) an application means, and c) an axial rod fixing the manual gripping means to the application means, the axial rod being an articulated rod with an upper arm and a lower arm forming a hinge by cooperation of a male element with a female element. The male element includes two lateral walls comprising a solid part between them, forming the axle. The female part includes a central wall, the central wall comprising two projections facing each other forming a central recess such that the female element forms a hub. The solid part has an external section forming a complete or partial order N regular polygon and the central recess has a homothetic internal section, such that angle α formed by the arms is equal to discrete predetermined and stable angular values. The applicator provides predetermined and stable angular values and easy assembly of the applicator.
Claims
exact text as granted — not AI-modified1 . Applicator of a cosmetic product, wherein the applicator cooperates in the axial direction with a receptacle having a threaded neck and containing the cosmetic product, the applicator and receptacle together forming a dispenser of the cosmetic product, the applicator comprising:
a) a manual gripping means, b) a means of application of the cosmetic product, c) an axial rod fixing the manual gripping means to the application means, the axial rod being articulated in an axial plane, including an upper arm fixed at its upper end to the manual gripping means, and a lower arm fixed at its lower end to the application means, the upper arm cooperating at its lower end with the upper end of the lower arm and forming a hinge having an axis radially perpendicular to the axial direction by cooperation of a male element forming an axle at one end of the two arms, with a female element forming a hub at one end of the other arm so as to enable rotation of the arms, the lower arm being rotated manually around a direction forming an angle α with the upper arm equal to 0° or not equal to 0°, wherein: 1) the male element includes two lateral walls oriented in the axial direction and facing each other, with a recessed part between the two lateral walls with a radial width L R and a non-recessed part or solid part forming the axle, 2) the female part includes a central wall oriented in the axial direction with a thickness less than the radial width L R such that the central wall can slide between the two lateral walls, the central wall comprising two projections facing each other forming a central recess and a peripheral recess such that the female element forms an open hub that can be assembled to the male element forming the axle by click fitting, the facing projections having a resilient elasticity and thus being capable of being temporarily separated under stress, during the click fitting or the rotation, 3) the non-recessed or solid part forming the axle has an external section forming a complete or partial order N regular polygon and the central recess has a homothetic internal section forming the regular polygon, such that the angle ox may be equal to at least two discrete adjacent angular values α 0 and α 1 , where α 0 <α 1 such that |α 1 −α 0 | is equal to 360°/N, where N is an integer number varying from 3 to 12.
2 . Applicator according to claim 1 wherein the solid part forming the axle includes a central axle connecting the lateral walls.
3 . Applicator according to claim 1 wherein the solid part forming the axle is composed of two lateral axle portions, each of the lateral axles being fixed to a lateral wall such that if necessary the lateral walls can be elastically separated during the click fitting of the arms or when the arms change from an angular position with angle α 0 to a neighboring angular position with angle αl, and more generally when the arms change from an angular position with angle αi to a neighboring angular position with angle α j .
4 . Applicator according to claim 1 wherein the upper arm and lower arm have the same generally circular cross section, the cross section being perpendicular to the axial direction.
5 . Applicator according to claim 4 wherein the lateral walls of the male element and the central wall of the female element cooperate in the hinge, such that the hinge has the generally circular cross section, particularly when the upper arm and lower arm are in line and the angle ox formed between them is equal to 0°.
6 . Applicator according to claim 1 wherein the upper arm carries the male element at its lower end and the lower arm carrying the female element at its upper end.
7 . Applicator according to claim 1 wherein the upper arm carries the female element at its lower end and the lower arm carrying the male element at its upper end.
8 . Applicator according to claim 1 wherein the peripheral recess of the female element is an axial peripheral recess so that click fitting of the arms is an axial click fitting.
9 . Applicator according to claim 1 wherein the peripheral recess of the female element is a lateral or radial peripheral recess, such that the click fitting of the arms is a lateral or radial click fitting.
10 . Applicator according to claim 1 wherein the lengths of the upper arm and lower arm denoted L s and L I respectively are such that L s +L I varies from 20 mm to 100 mm, and L s /L I varies from 0.1 to 10.
11 . Applicator according to claim 1 wherein the lower end of the lower arm is a tapered end.
12 . Applicator according to claim 1 wherein the lower end of the lower arm includes an attachment means of the application means.
13 . Applicator according to claim 12 wherein the attachment means is an axial recess forming a blind hole capable of cooperating with a portion of the support of the application means.
14 . Applicator according to claim 1 wherein the angle α 0 is equal to 0° to 15°.
15 . Applicator according to claim 1 wherein N is an integer number varying from 3 to 12 and α 0 is equal to 0°, and the discrete angular values are as follows for each value of N:
