Abstract

A method for providing a desired fragrance includes securing a tacky attachment surface of a pad of an air freshener to a surface by mechanical or specific adhesion. The air freshener includes a scent material carried by and dispersable through a coherent, flexible and resilient polymer carrier material. The pad is selectively removed from the surface. The pad can be selectively re-secured at a different position on the surface.

Claims (70)

1. A method for providing a desired fragrance, comprising the steps

a) securing a tacky attachment surface of a pad of an air freshener to a surface by mechanical or specific adhesion, the air freshener including a scent material interspersed in and dispersible through a coherent, flexible and resilient polymer carrier material; and

b) selectively removing the pad from the surface the tacky attachment surface of the pad held by mechanical or specific adhesion on the surface; and

c) selectively re-securing the same tacky attachment surface of the pad at a different position on the surface or on a different surface by mechanical or specific adhesion.

2. A method in accordance with claim 1 , further comprising the step of:

deforming the polymer carrier material, the polymer carrier material being resilient and substantially returnable to an original configuration.

3. A method in accordance with claim 1 , wherein the polymer carrier material includes a polyurethane gel and the scent material includes a scented oil.

4. A method in accordance with claim 1 , wherein the polymer carrier material includes a polymeric material having a glass transition temperature greater than approximately 110° F.

6. A method in accordance with claim 1 , further comprising:

a barrier, disposed between the carrier material and the pad, being smaller than the carrier material and the pad such that a perimeter of the carrier material contacts a perimeter of the pad.

7. A method in accordance with claim 1 , further comprising:

indicia, disposed between the carrier material and the pad; and

the carrier material being light transmissive in at least a translucent manner such that the indicia is visible through the carrier material.

8. A method in accordance with claim 1 , wherein the carrier material is a member selected from the group consisting of polyurethane, polyacrylate, polybutadiene, ethylene propylene elastomer, silicone, natural rubber, synthetic rubber, styrene/butadiene block copolymer, polyvinylchloride, ethylene vinyl acetate, polypropylene, ethylene/methacrylic acid copolymer, and mixtures thereof.

9. A method in accordance with claim 8 , wherein the carrier material is a member selected from the group consisting of polyurethane, polyacrylate, polybutadiene, ethylene propylene elastomer, styrene/butadiene block copolymer, and mixtures thereof.

10. A method in accordance with claim 9 , wherein the carrier material is light transmissive in at least a translucent manner.

11. A method in accordance with claim 1 , wherein the carrier material is a thermoplastic elastomer.

12. A method in accordance with claim 11 , wherein the thermoplastic elastomer is selected from the group consisting of polyurethanes, polyamides, copolyesters, and styrene-butadiene-styrene polymers, elastomer/thermoplastic blends, and combinations thereof.

13. A method in accordance with claim 12 , wherein the scent material in the thermoplastic elastomer is dispersable at a substantially constant rate for at least a time period of between approximately two days and thirty days.

14. A method in accordance with claim 1 , wherein the carrier material includes a polymer body that is a polymerization product of at least a diisocyanate prepolymer and a scented oil.

15. A method in accordance with claim 14 , wherein the polymer body and scent material includes a polymerization product of:

a) a polyether polyol;

b) a diphenylmethane diisocyanate (MDI) prepolymer; and

c) a scented oil.

16. A method in accordance with claim 1 , wherein the carrier material is light transmissive in at least a translucent manner.

17. A method for providing a desired fragrance, comprising the steps of:

a) securing a tacky attachment surface of a pad of an air freshener to a surface by mechanical or specific adhesion, the air freshener including a scent material interspersed in and dispersible through a coherent, flexible and resilient polymer carrier material that is light transmissive in at least a translucent manner; and

b) selectively removing the pad held by mechanical or specific adhesion from the surface.

18. A method in accordance with claim 17 , further comprising the step of:

selectively re-securing the pad at a different position on the surface.

19. A method in accordance with claim 17 , further comprising the step of:

deforming the polymer carrier material, the polymer carrier material being resilient and substantially returnable to an original configuration.

20. A method in accordance with claim 17 , wherein the polymer carrier material includes a polyurethane gel and the scent material includes a scented oil.

21. A method in accordance with claim 17 , wherein the polymer carrier material includes a polymeric material having a glass transition temperature greater than approximately 110° F.

22. A method in accordance with claim 17 , wherein the scent material disperses at a substantially constant rate for at least a time period of between approximately two days and thirty days.

23. A method in accordance with claim 17 , further comprising:
