Abstract

Cosmetic applicators, blenders and aids, and more particularly to a resilient blender that includes an open-cell memory foam surface component that is easily cleanable or disposable in combination with a resilient core component. Further, the core component of the system includes a spring structure for greatly accelerating the rebound of the blender surface from a compressed state to a repose memory or de-compressed state.

First claim

What is claimed is:

1. A cosmetic applicator comprising:
a resilient body having a skin-contacting portion and a grip portion shaped for gripping by a user, where the grip portion of the resilient body is configured for finger-actuated manipulation to alter a pressure of an interior chamber to adjust compressibility and rebound characteristics of the resilient body;
a surface portion of the resilient body comprising a fluid permeable material having a first resilient characteristic; and
a core component of the resilient body including the interior chamber and having an elastomeric wall adapted to deflect away from the interior chamber and away from the grip portion upon pressurization of the interior chamber caused by deformation of the resilient body at the skin-contacting portion, where the elastomeric wall enhances rebounding of the resilient body from a compressed tensioned shape to a de-compressed repose shape.

2. The cosmetic applicator of claim 1 wherein the resilient body includes a spring structure comprising a metal material.

3. The cosmetic applicator of claim 1 wherein the resilient body includes a spring structure comprising a NiTi material.

4. The cosmetic applicator of claim 1 wherein the resilient body includes a spring structure comprising a polymer.

5. The cosmetic applicator of claim 1 further comprising a fluid impermeable layer intermediate the surface portion and the core component.

6. The cosmetic applicator of claim 5 further where the surface portion is removable from the core component.

7. The cosmetic applicator of claim 6 where the fluid impermeable layer is carried by the surface portion.

8. A cosmetic applicator comprising:
a resilient applicator body comprising a surface portion and a grip-portion adapted for gripping by a user, where the grip-portion is axially spaced from the surface portion;
the surface portion of the resilient applicator body comprising a fluid permeable resilient foam material adapted for tissue contact;
a core portion of the resilient applicator body including at least one interior chamber at least partially surrounded by an elastomeric wall; and
where the grip-portion of the resilient applicator body is configured for finger-actuated manipulation to deform an elastomeric wall adjacent to the grip-portion to alter a pressure of the at least one interior chamber to thereby adjust compressibility and rebound characteristics of the resilient applicator body.

9. The cosmetic applicator of claim 8 where the surface portion and the core portion have different resilient characteristics.

10. The cosmetic applicator of claim 8 where the surface portion has uniform properties around the surface portion of the resilient applicator body adapted for tissue contact.

11. The cosmetic applicator of claim 8 where the surface portion has non-uniform properties around the surface portion of the resilient applicator body adapted for tissue contact.

12. The cosmetic applicator of claim 8 wherein the at least one interior chamber comprises an elastomeric wall adapted to bulge away from the at least one interior chamber upon pressurization of the at least one interior chamber.

13. The cosmetic applicator of claim 12 wherein the elastomeric wall is adapted to deflect away from interior chamber upon pressurization of the interior chamber caused by deformation of the surface portion against tissue such that the elastomeric wall enhances rebounding of the surface portion.

14. The cosmetic applicator of claim 8 wherein a wall of the grip-portion is thicker than a wall of the surface portion.
