Abstract

Hygienic cosmetic applicators, blenders and aids, and more particularly to a soft, resilient blender system that includes an open-cell memory foam surface component that is easily cleanable or disposable in combination with a core resilient component that is fluid impermeable. Hygienic cosmetic applicators, blenders and aids including a core component with one or more spring elements for greatly accelerating the rebound of the blender surface from a compressed state to a repose memory state.

First claim

What is claimed is:

1. A cosmetic applicator comprising:
a resilient body having a central axis adapted and shaped for gripping with the fingers of a user;
a surface portion of the body comprising a fluid permeable layer overlying a fluid impermeable layer;
an interior portion of the body including a plurality of spring elements for imparting to the body a selected rebound parameter for rebounding the body from a compressed tensioned shape to a decompressed repose shape.

2. The cosmetic applicator of claim 1 wherein the plurality of spring elements is spaced apart about the central axis.

3. The cosmetic applicator of claim 2 wherein the plurality of spring elements is asymmetrically spaced apart about the central axis.

4. The cosmetic applicator of claim 2 wherein the plurality of spring elements differ in spring strength.

5. The cosmetic applicator of claim 2 wherein the plurality of spring elements differ in orientation relative to the central axis.

6. A cosmetic applicator comprising:
a resilient body shaped for gripping with the fingers of a user;
a surface portion of the body comprising a porous memory foam having a first inherent rebound characteristic to rebound from a compressed tensioned shape to a repose memory shape; and
a core portion of the body comprising at least one helical spring element imparting to the body a second rebound characteristic that differ from the first inherent rebound characteristic.

7. The cosmetic applicator of claim 6 wherein the surface portion is detachably coupled to the core portion.

8. The cosmetic applicator of claim 6 wherein an interface between the surface portion and the core portion is fluid impermeable.

9. A cosmetic applicator comprising:
a resilient body shaped for gripping with the fingers of a user;
a surface portion of the body comprising a porous memory foam having a first inherent rebound characteristic to rebound from a compressed tensioned shape to a repose memory shape; and
a core portion of the body comprising a plurality of spring elements imparting to the body a second rebound characteristic that differ from the first inherent rebound characteristic.

10. The cosmetic applicator of claim 9 wherein the surface portion is detachably coupled to the core portion.

11. The cosmetic applicator of claim 9 wherein an interface between the surface portion and the core portion is fluid impermeable.
