  • Patent number: 4785642
    Abstract: A decorative clip for use as a jewelry item is disclosed which shines and glitters in the dark and emits perfume. This shining and glittering effect is achieved by placing an LED or an LCD device powered by a small battery beneath a decorative housing. When the clip is worn, the circuit between the battery and the LED or LCD is completed such that current may flow. In addition, a perfume dispenser is provided integral to the clip such that a fragrance is continuously emitted without interacting with the body chemistry of the wearer of the clip. The perfume dispenser is detachable so that the perfume may be changed or refilled as the wearer desires.
