Patent# US 6842218, which refers to the Scent Delivery System, allows the user to pick his or her own smells, a rather dubious thrill to begin with. It works by injecting scent into an airflow created by the fan or canister, and creates scented air, which is carried to the nose by the flow of air via a nose mask or facemask. If you are wondering why anyone would want such a thing, join the club whose membership is fast disappearing from a lack of interest.
This questionably useful scent delivery system can be used with a portable system as well as a multi-media device and can deliver one scent or a plurality of scents to a user’s nose. The invention is a scented air delivery device comprised of a conduit having two open ends and at least one side opening in a side wall, a nasal interface affixed to one of the open ends and a means for creating an air flow. (If you are still wondering why, you are still not alone.)
The inventor claims that this system is both simple and inexpensive to manufacture. The question remains: Who would want to buy it? This same question can be asked after reading about the following ideas from other inventors on the topic of scents. Consider Steve Levenstein’s piece, “Japan’s Aging Population Deals with Old Man Smell” and Lisa Zyga’s article: “Can the Smell of Rotten Eggs Make You Live Longer?.
I don’t know about you, but I prefer that the smells in my life come natural sources, like the lingering scent of fine perfume and a flower garden soon after a rain.
