Abstract

An air freshener device includes a scent material interspersed within a polymer body or a polymer gel, and capable of dispersing out of the polymer gel. The polymer body and a polymer gel can be flexible and compressible, and also resilient and returnable to its original configuration. The air freshener can have at least one vent rod configured to engage an air vent, a head pivotally coupled to the at least one vent rod and a polymer body associated with the head and at least one vent rod and containing scent material. The air freshener also may be combined with a packaging system to present the air freshener for purchase, and have a pivotal head pivoted to display the head in the packaging.

Claims

1. An air freshener device, comprising:

at least one vent rod configured to engage an air vent;

a scent material, associated with the at least one vent rod, capable of diffusing out of the clip to surrounding air; and

a head pivotally coupled to the at least one vent rod, with a face and indicia thereon.

2. A device in accordance with claim 1, further comprising at least two vent rods forming a clip.

3. A device in accordance with claim 1, further comprising a hinge between the head and the at least one vent rod configured to allow the head to pivot with respect to the at least one vent rod.

4. A device in accordance with claim 1, wherein the at least one vent rod has a longitudinal axis and the head and the at least one vent rod have at least two configurations, including:

a storage configuration wherein a surface of the face is substantially parallel with the longitudinal axis of the at least one vent rod; and

a use configuration wherein the surface of the face is transverse to the longitudinal axis of the at least one vent rod.

5. A device in accordance with claim 1, wherein the head is removably coupled to the at least one vent rod.

6. A device in accordance with claim 1, wherein the at least one vent rod includes a coherent elastomeric polymer body.

7. A device in accordance with claim 6, the polymer body further comprising a recess, configured to increase an exposed surface area of the polymer body.

8. A device in accordance with claim 6, wherein the elastomeric polymer is a thermoplastic elastomer.

9. A device in accordance with claim 6, wherein the polymer body is a polymerization product of at least a diisocyanate prepolymer and a scented oil.

10. An air freshener device, comprising:

at least one vent rod configured to engage an air vent;

a head pivotally coupled to the at least one vent rod;

a coherent elastomeric polymer body associated with the at least one vent rod and the head; and

a scent material, interspersed within the polymer body, capable of diffusing out of the polymer body to surrounding air.

11. A device in accordance with claim 10, further comprising at least two vent rods forming a clip.

12. A device in accordance with claim 10, wherein the polymer body is coupled to the at least one vent rod.

13. A device in accordance with claim 12, wherein the at least one vent rod comprises a projection extending through the polymer body to couple the polymer body to the at least one vent rod.

14. A device in accordance with claim 10, wherein the polymer body is coupled to the head.

15. A device in accordance with claim 10, the polymer body further comprising a recess, configured to increase an exposed surface area of the polymer body.

16. A device in accordance with claim 10, wherein the head is removably coupled to the at least one vent rod.

17. An air freshener device in combination with a packaging system configured to present the air freshener device for purchase, comprising:

the air freshener device comprising a head pivotally coupled to at least one vent rod containing a scent material; and

a container, containing the air freshener device;

wherein the container is configured to display a face of the head in a position substantially parallel with a longitudinal axis of the at least one vent rod, and

wherein the head is capable of pivoting to a different position for use, with the face transverse to the longitudinal axis of the at least one vent rod.

18. A system in accordance with claim 17, wherein the scent material is interspersed within the at least one vent rod and capable of diffusing out of the at least one vent rod to the surrounding air.

19. A system in accordance with claim 17, wherein the at least one vent rod further comprises a coherent elastomeric polymer body coupled to the clip, and the scent material is interspersed within the coherent elastomeric polymer body and capable of diffusing out of the coherent elastomeric polymer body to the surrounding air.

20. A device in accordance with claim 17, wherein the head is removably coupled to the at least one vent rod.
