Abstract

The invention concerns an applicator for pasty, liquid or semi-liquid cosmetics materials such as mascara. Known applicators, in which an elongate applicator member formed integrally with a closure for a container of the material, may comprise a twisted wire brush carried at the end of a support shaft, have the disadvantage that the geometry of the brush is fixed. Thus a brush ideal for one type of application will be generally unsuitable for another. Other known applicators having fine end bristles suffer the problem that the bristles become damaged upon insertion through a narrow wiper opening of the material container. The arrangement of the invention avoids these problems by providing a cover for the material retaining part of the elongate member, relative movement between this cover and elongate member being permitted to provide selective and/or adjustable covering of the material retaining part. Thus, the amount of this part which is exposed for use can be varied. The configuration of the exposed part may also change.

Claims

1. An applicator for the application of a pasty, liquid or semi liquid cosmetic product comprising:

an elongate member having a product-retaining portion comprising elements or material for retaining the cosmetic product; and

a cover member for at least partially covering said elements or material of said product-retaining portion;

said elongate member and said cover member being relatively movable to vary the covering of said elements or material of said product-retaining portion by said cover member.

2. An applicator according to claim 1 wherein said elongate member and said cover member are relatively movable so as to permit varying amounts of the product-retaining portion to be exposed for use.

3. An applicator according to claim 1 wherein said elongate member and said cover member are relatively movable between a first relative position in which the product retaining portion is fully exposed for use and a second relative position in which it is fully covered.

4. An applicator according to claim 1 wherein said elongate member and said cover member are relatively movable so as to alter the configuration of the product-retaining portion.

5. An applicator according to claim 1 wherein said cover member comprises a sleeve disposed over said elongate member.

6. An applicator according to claim 5 wherein said product-retaining portion is an end portion of said elongate member and wherein said sleeve and said elongate member are relatively axially movable to vary the amount of the material retaining portion which projects from an open end of said sleeve.

7. An applicator according to claim 5, wherein said product retaining portion is an end portion of said elongate member, and wherein a corresponding end portion of the sleeve is adapted so that relative rotation between the sleeve and the elongate member causes said end portion of the sleeve variably to cover said product retaining portion.

8. An applicator according to claim 5, further comprising manually operable means for producing relative movement between said sleeve and said elongate member.

9. An applicator according to claim 8 wherein said manually operable means comprises a handle having a first part to which one of said sleeve and elongate member is fixedly attached and a second part which is movable relative to the first part;

and

means coupling said second part to the other of said sleeve and elongate member, said coupling means causing the relative movement between said sleeve and elongate member in response to the relative movement between said first and second parts.

10. An applicator according to claim 9 wherein said one of said sleeve and elongate member which is fixedly attached to said first part of the handle is said sleeve.

11. An applicator according to claim 9 wherein said handle is a closure cap adapted to be secured to the neck of a container for the cosmetic material with the sleeve and elongate member projecting into said container.

12. An applicator according to claim 4 wherein said product retaining portion comprises a central support stem a forward end of which carries a multiplicity of flexible, circumferentially spaced radially projecting filaments, such as bristles or teeth, constituting paid elements, and wherein said cover member comprises a sleeve disposed over said elongate member, said sleeve having a forward end opening which, when the sleeve moves forwardly or the elongate member moves rearwardly, engages behind said filaments and causes them to flex to an axially forwardly projecting orientation to form an axial end brush projecting forwardly of said end of said stem.

13. An applicator according to claim 12 wherein said forward end opening of said sleeve has an inwardly inclined frusto-conical surface to engage said filaments.

14. An applicator according to claim 13 wherein said filaments are adapted to be flexed forwardly by engagement by said frusto-conical surface, the forward flexing causing the filament tips to meet on the axis so that the filaments form a circumferential curtain enclosing a central reservoir for the cosmetic material.

15. An applicator according to claim 6 wherein said product-retaining portion comprises a central stem with said product-retaining elements or material projecting radially therefrom, and wherein said open end of said sleeve comprises an opening through which the stem can project, and which is smaller than the internal cross-sectional area of the sleeve so that as the product-retaining elements or material enter the sleeve through said opening a radially inner part of said elements or material is wiped, and thereby cleaned, by said opening.

16. An applicator according to claim 3 wherein said elongate member comprises a shaft, and wherein said product-retaining portion comprises a plurality of flexible filaments extending substantially axially from one end of the shaft to form a brush, said cover member comprising a sleeve within which said shaft is disposed, said elongate member and said sleeve being relatively axially displaceable so that in said first relative position said brush projects from said sleeve and in said second relative position said brush lies wholly within said sleeve.

17. An applicator according to claim 1 wherein said cover member includes on an outer surface thereof surface formations constituting a further product retaining portion which can be used for product retention and application

18. An applicator according to claim 1 wherein said product-retaining portion is a brush comprising a multiplicity of bristles.

19. An applicator according to claim 18 wherein said brush comprises a support stem from which said bristles project laterally.

20. A cosmetic applicator for a pasty, liquid or semi liquid cosmetic product, comprising:

a central elongate member having a portion including a stem and a plurality of elements projecting laterally from said stem; and

a cover member for at least partially covering said portion of said elongate member;

wherein the cover member and elongate member are relatively movable to vary the covering of said portion of said elongate member by said cover member, and wherein an outer part of said cover is provided with means for retaining the cosmetics product thereon.
