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. In addition, the polymer body and the polymer gel can have a freestanding, self-supported, three-dimensional shape. The air freshener can include a tacky or clingy attachment surface to contact and cling to a support surface by mechanical or specific adhesion.
Claims59
An air freshener device, comprising:
- a) a coherent elastomeric polymer body;
- and
- b) a scent material, interspersed within the body, capable of diffusing out of the body to surrounding air.
An air freshener device, comprising:
- a) a thermoplastic elastomer having a freestanding, self-supported, three-dimensional shape;
- and
- b) a scent material, interspersed within the thermoplastic elastomer, capable of diffusing out of the thermoplastic elastomer to surrounding air.
An air freshener device, comprising:
- a) a pad with a tacky attachment surface configured to contact and cling to a support surface;
- b) a polymer carrier material, coupled to the pad, that is flexible and compressible under an applied force, and resilient and substantially returnable to an original configuration upon removal of the applied force;
- and
- c) a scent material, interspersed within the polymer carrier material, capable of diffusing out of the polymer carrier material to surrounding air.
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 carried by and dispersable through a coherent, flexible and resilient polymer carrier material;
- and
- b) selectively removing the pad from the surface.
An air freshener device, comprising:
- a) a polymer gel formed of a thermoplastic elastomer having a glass transition temperature greater than approximately 110° F.;
- and
- b) a scent material, interspersed within the polymer gel, capable of diffusing out of the polymer gel to surrounding air.
