Abstract

A cosmetic container and applicator assembly is provided wherein the applicator head and a wiper within the container both have non-circular configurations such that the wiping effect achieved by the wiper can be varied by altering the rotational position of the applicator relative to the wiper.

Claims

1. A cosmetic container and applicator assembly comprising:

a container for cosmetic material having a container opening between the inside and outside thereof, a wiper in or aligned with said container opening, the wiper having a non-circular wiper aperture at least part of which is smaller in cross-section than said container opening, no portion of said container opening between said wiper aperture and the outside of the container having a cross-section as small as the cross-section of said wiper aperture; and

an applicator comprising a shaft with radially extending projections to hold cosmetic material, the applicator being adapted for insertion into the container through said container opening so that at least the part on which said projections are formed passes through said wiper aperture, the size and circumferential distribution of said projections being such that the amount of material wiped from the applicator as it is withdrawn from the container can be varied by rotation of the applicator about its axis relative to the wiper.

2. An assembly according to claim 1 wherein the applicator has at least one longitudinal row of said projections.

3. An assembly according to claim 2 wherein the applicator has first and second said rows of projections, the projections of said first row being longer than the projections of said second said row.

4. An assembly according to claim 2 wherein said projections include a longitudinal row of flexible bristles.

5. An assembly according to claim 4 wherein said bristles are integrally molded with the shaft.

6. An assembly according to claim 1 wherein the wiper has a central aperture with at least one slot extending radially therefrom.

7. An assembly according to claim 6, wherein the shaft has a portion extending between the wiper and the projections when the applicator is fully inserted into the container and that portion of the wiper which forms the central aperture engages the shaft to wipe said portion of the shaft upon withdrawal of the applicator from the container.

8. An assembly according to claim 6 wherein the wiper has at least two said radial slots of different sizes.

9. An assembly according to claim 6 wherein the applicator has a plurality of circumferentially spaced axially extending rows of projections, and the wiper has a plurality of circumferentially spaced slots extending radially from said aperture, the spacing of the slots corresponding with the spacing of the rows of projections.

10. An assembly according to claim 9 wherein the number of rows of projections corresponds with the number of slots.

11. An assembly according to claim 9 wherein the projections and the radial slots are in register in only one rotational position of the applicator relative to the wiper.

12. An assembly according to claim 6 or claim 9 wherein said radial slot or slots is or are formed in a conical portion of the wiper.

13. An assembly according to claim 1 wherein the aperture in the wiper is located within the container, axially spaced from the container opening.

14. An assembly according to claim 1 wherein the wiper is resiliently deformable.

15. An assembly according to claim 1 wherein the applicator projects from the inside of a cap for the container, and extends into the container through the wiper when the cap is fitted to the container.

16. As assembly according to claim 15 wherein the cap and the container carry markings to indicate the rotational position of the applicator to the wiper.

17. An assembly according to claim 15 wherein the cap is fitted to the container by means of a screwthread.

18. An assembly according to claim 17 wherein the screwthread is such that the cap is released from the container at a position in which the radial projections on the applicator nearest the cap are immediately below the wiper aperture.
