Abstract:
An air freshener has a rigidifying core defining a central axis, and an outer portion or sleeve contacting the core that is formed from one or more fragrance loaded polymers. Together, the core and outer portion are shaped to surround a first axis perpendicular to the central axis. The air freshener is made by injection molding a first shot of at least one polymer material to form the core, and injection molding a second shot of at least one polymer material incorporating one or more fragrance materials over or onto or into at least a portion of the core. The second shot of polymer material may be stretched about the portion of the core during injection molding, and may flow into a first hole formed in the core at or near the core distal end, and fills a second hole formed in the core at or near the core proximal end.
