Concave-convex roller assembly
First Claim
1. An applicator for applying a cosmetic to a skin surface, comprising:
- a handle having a longitudinal axis and opposite ends;
a first rolling member having a concave application surface and a first axial dimension, the first rolling member mounted at one end of the handle for rotation about a fixed axis extending laterally of the longitudinal axis of the handle;
not more than one second rolling member having a convex application surface and a second axial dimension, wherein the second rolling member is a wheel enabled for biaxial rotation or wherein the second rolling member is a ball, the second rolling member rotatably mounted at the opposite end of the handle; and
means for mounting the first and second rolling members to respective opposite ends of the handle;
wherein a ratio of the first axial dimension to the second axial dimension is in the range of from about 5;
1 to about 2;
1, and wherein the respective application surfaces of the first and second rolling members are configured to uniformly apply, distribute and blend the cosmetic on the skin surface of a user'"'"'s face and neck.

Abstract
A dual-ended applicator is provided. The applicator includes a handle, a first roller having a broad concave surface at one end of the handle, and a second, ball-like roller having a convex surface, at the opposite end of the handle. The first roller, having a greater axial length and surface area than does the second roller is intended for applying a cosmetic to broader convex areas of the skin. The second roller, having a lesser axial dimension and surface area as compared with the first roller is intended for distributing a cosmetic to the narrower, concave areas of the skin. The first roller is mounted on the applicator so as to rotate about a fixed axis lateral to the longitudinal axis of the applicator, and will move in straight paths along the skin, in line with the longitudinal axis of the applicator. The second, ball-like roller is mounted on the applicator so as to travel along both straight and curved paths, automatically adjusting between positions as the applicator is moved along the skin surface.
