Air freshener and method
View Patent ↗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. In addition, the polymer body and the polymer gel can have a freestanding, self-supported, three-dimensional shape. The air freshener can be light transmissive in at least a translucent manner, and can have indicia visible therethrough. In addition, the air freshener can have a light source capable of emitting light visible through the body. A vehicle accessory power plug can be coupled to the light source, and sized and shaped to be inserted into a vehicle accessory power socket.
1. An air freshener device, comprising:
a) a head with indicia;
b) a clip coupled to the head extending perpendicularly outward from the head, and sized and shaped to be inserted into a vehicle air vent and clipped to a vehicle air vent cover such that the head is adjacent the vehicle air vent, and including a pair of vent rods sized and shaped to be inserted into the vehicle air vent and having a plurality of protrusions;
c) a pair of coherent elastomeric polymer bodies having a plurality of apertures, each of the bodies coupled to a different one of the vent rods via coupling of the plurality of apertures with the plurality of protrusions, and insertable into the vehicle air vent with the vent rods; and
d) a scent material, interspersed within the bodies, capable of diffusing out of the bodies to surrounding air.
2. A device in accordance with claim 1 , wherein the elastomeric polymer is 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.
3. A device in accordance with claim 2 , wherein the elastomeric polymer is selected from the group consisting of polyurethane, polyurethane gel, polyacrylate, polybutadiene, ethylene propylene elastomer, styrene/butadiene block copolymer, and mixtures thereof.
4. A device in accordance with claim 1 , wherein the elastomeric polymer is a thermoplastic elastomer.
5. A device in accordance with claim 4 , wherein the thermoplastic elastomer is selected from the group consisting of polyurethanes, polyamides, copolyesters, styrene-butadiene-styrene polymers, elastomer/thermoplastic blends, and combinations thereof.
6. A device in accordance with claim 1 , wherein the polymer bodies include polyurethane and the scent material includes a scented oil.
7. A device in accordance with claim 1 , wherein the polymer bodies are a polymerization product of at least a diisocyanate prepolymer and a scented oil.
8. A device in accordance with claim 7 , wherein the polymer bodies and scent material include a polymerization product of:
a) a polyether polyol;
b) a diphenylmethane diisocyanate (MDI) prepolymer; and
c) a scented oil.
9. A device in accordance with claim 1 , wherein the scent material in the polymer bodies disperses at a substantially constant rate for at least a time period of between approximately two days and thirty days.
10. A device in accordance with claim 1 , wherein the polymer bodies includes a polymeric material with a glass transition temperature greater than approximately 110° F.
11. A device in accordance with claim 1 , wherein the elastomeric polymer includes a polyurethane gel.
12. A device in accordance with claim 1 , wherein the elastomeric polymer is selected from the group consisting of polyurethane, polyacrylate, polybutadiene, ethylene propylene elastomer, styrene/butadiene block copolymer, and mixtures thereof, the elastomeric polymer being a solid material.
