发明名称 Wooden air freshener with fragrance loading chamber
摘要 A wooden, refillable container having an interior fragrance loading chamber at the base is filled with air freshening oil. A closure is secured to the bottom of the container to hold the oil inside the chamber, to allow removal for charging and recharging, and to protect the surface on which the container is from contact with the oil. The oil migrates through the wood along the capillaries of the wood grain until it reaches the outside wooden surface of the container. After exposure to the open air, the oil vaporizes, thereby releasing the fragrance into the air. The wood acts as a metering device for the gradual release of the air freshening agent. As the oil evaporates, the wooden member loses its luster and lightens in appearance, signaling that more air freshening agent is needed. This change in appearance allows an observer to easily determine whether the chamber needs to be refilled.
